    [0001] This patent application claims priority from Italian patent application no. 102019000001797 filed on February 7, 2019 . Technical background of the invention
    [0002] The present invention relates to a motion transmission device between a first and a second component with a force limiter function, in particular applicable to a lighting device for vehicles, where the first component is an electric motor and the second component is a reflector or lighting element of the lighting device, which must be moved, for example to direct a light beam generated by the lighting device while going round a bend and/or to adjust the direction of the light beam according to the load (passengers/baggage) weighing on the vehicle. Prior Art
    [0003] As known, a vehicle lighting device comprises a cup-shaped body or housing, generally made by moulding a synthetic plastic material, at least one lighting element housed in the cup-shaped body, fitted with a reflector or not, and a transparent element placed to close a front opening of the cup-shaped body, in use facing the direction of travel of the vehicle.
    [0004] In order to prevent the accidental glare of other vehicles, it must be possible to adjust the vertical output direction of the light beam generated by the lighting device in relation to the respective weight of the vehicle, in particular in the presence of luggage and/or passengers in the rear seat. For this purpose, an electro-mechanical device is used which moves the reflector or lighting element appropriately (at the user's or sensor's command) and which consists of an electric motor or linear actuator which acts on the reflector or lighting element via a mechanical transmission device.
    [0005] However, particularly after repeated and frequent use, the mechanical transmission device may accidentally jam, causing an overload of the electric motor or actuator, and consequent premature wear or damage to the same.
    [0006] This problem is all the more present in adaptive lighting devices, where the reflector or lighting element is, for example, rotated routinely, for example to direct the light beam according to the curves performed by the vehicle.
    [0007] Lastly, it should be noted that there are also projectors without an external lens, in which the adjustment mechanism could be stressed not only by accidental jamming thereof but also by external events such as vandalism or in any other case of excessive force applied to the lighting elements. Summary of the invention
    [0008] The purpose of the present invention is to provide a motion transmission device between a first and a second component, in particular applicable to a lighting device for vehicles, which is free of the drawbacks of the prior art, in particular having a force limiter function, and which is also simple and economical to make, highly reliable and small in size.
    [0009] According to the invention, a motion transmission device between a first and a second component with a force limiter function, in particular applicable to a lighting device for vehicles, is therefore provided, as defined in the appended claims.
    [0010] In particular, the motion transmission device according to the invention comprises a support for fixedly receiving the first component, an output shaft of the first component, axially mobile with respect to the support, a first shaft configured to be constrained in use to the second component, and a mechanical connection device between the axially mobile output shaft and the first shaft.
    [0011] According to the invention, the mechanical connection device comprises in turn: a cup-shaped body fixed to the first shaft and slidably coupled to the support parallel to the output shaft and coaxially thereto by means of at least one pair of lateral guides fixed to the support; a bushing, mounted inside the cup-shaped body, which is coaxial and slidable with respect thereto, the bushing being axially constrained in a fixed way to the output shaft so as to move integrally therewith; at least one pair of radial holes, made in a radially inner lateral surface of the cup-shaped body, said lateral surface cooperating with the bushing; at least one pair of opposed pegs, housed so that they can slide within respective radial seats of the bushing, which are provided within said bushing and until they pass through a radially outer lateral wall of the bushing, the radial seats further housing first springs which cooperate with the pegs, the first springs and the radial seats being configured to cause the pegs to selectively assume an extracted position, in which a first end of the pegs radially projects in a cantilever fashion from the bushing to engage the radial holes of the cup-shaped body and fix the cup-shaped body to the bushing, and a retracted position, in which the first end of the pegs is at least partially housed in a concealed fashion in the radial seats against the action of the first springs so as not to engage the radial holes of the cup-shaped body; and second springs, packed between the support and the cup-shaped body and between the support and respective shoulder elements, which are fixed with respect to the cup-shaped body and are arranged, with respect to the support, on the side opposite the cup-shaped body.
    [0012] Furthermore, the first ends of the pegs are delimited by respective surfaces, arranged obliquely with respect to an axis of symmetry of the output shaft and of the bushing and configured to cooperate with a perimetral edge of the radial holes so as to push the pegs towards the retracted position, against the action of the first springs, as a result of any axial load applied in use to the first shaft that exceeds a threshold value.
    [0013] In this way, when an axial stress greater than a threshold value chosen in the design phase is applied to the first shaft, the pegs are brought by the radial component of the axial stress, resulting from the presence of the oblique surfaces of the ends of the pegs, into the retracted position.
    [0014] In this retracted position of the pegs, the bushing is no longer axially constrained to the cup-shaped body and is therefore free to move axially with respect to the same, as is the support, to which it is connected by means of the output shaft, against the action of the second springs.
    [0015] As a result, the output shaft, even if it continues to move under the action of the first component, which is generally an electric motor or actuator, never receives axial stress higher than the established threshold value, preserving the first component.
    [0016] The established threshold value is determined in the design phase by appropriately sizing the first and second springs and the angle of inclination of the oblique surfaces with respect to the axis of movement of the output shaft.
    [0017] According to a preferred embodiment of the invention, the mechanical connection device further comprises a second shaft configured to fixedly couple, on one side, to the output shaft of the first component and, on the opposite side, to the bushing; in addition, the second shaft connects to the bushing by means of a ball joint and, preferably, by snap action.
    [0018] The bushing preferably comprises an annular or cup-shaped drum, preferably cylindrical, which has a first end facing the first shaft and provided with the radial seats for the pegs and for the first springs; a cover for closing a second end of the drum, which is opposite to the first end and is open towards the support, the cover being provided with a hole for receiving the output shaft through it as far as into the drum; and a spherical joint, which fixedly receives the output shaft and cooperates in contact with a first inner lateral surface of the drum, the spherical joint being axially blocked inside the drum by the cover.
    [0019] Finally, to facilitate the assembly of the transmission device, the cup-shaped body is divided into two elements consisting of an annular element coupled frontally to a cup-shaped element and integrally connected to each other by means of detachable connection members, preferably screws; the cup-shaped element being provided with the radial holes and both the annular and cup-shaped elements being coaxial and configured to slidingly receive inside them the bushing.

Detailed description
    [0021] With reference to Figure 1, reference numeral 1 globally denotes a front headlamp for motor vehicles, configured to be fixed in a known manner, not illustrated for the sake of simplicity, to the chassis of a vehicle (also known and not illustrated).
    [0022] The lighting device 1 comprises a housing 2, generally cup-shaped, a light source 3, a reflector 4 and a lens 5, either clear (i.e. not altering a light beam L produced by the light source 3) or optically active, which closes the housing 2 at the front.
    [0023] In order to direct the light beam L, simply to compensate for changes in the payload (passengers and/or luggage) of the vehicle (trim adjustment) or/and for example, to make the light beam L follow the bends made by the vehicle (adaptive lighting function), the reflector 4 or, if absent, directly the light source 3, can be rotated vertically and/or horizontally by means of an adjustment device 6, known in its general structure, comprising an electric motor or actuator 7, a linear motion transmission device 8 from the motor/actuator 7 to the reflector 4 (or directly to the light source 3) and a manual trim adjuster 9, known and illustrated only schematically by dotted lines by a block, for simplicity.
    [0024] More generally, the motion transmission device 8 is used to transmit a linear motion between a first component (in the example shown, consisting of the motor/actuator 7) and a second component, the orientation/trim of which must be varied, in the example shown, consisting of the reflector 4, but more generally also consisting of light source 3 alone.
    [0025] According to the invention, the transmission device 8 is designed with a force limiter function to protect the first component or motor/actuator 7 from any overloads that could damage it.
    [0026] For this purpose, the transmission device 8 (Figure 2) comprises a support 10 for fixedly receiving the first component 7, an output shaft 11 of the first component, such output shaft 11 being axially mobile with respect to the support 10, a first shaft 12, configured to be constrained in use to the second component 4 (or 3), and a mechanical connection device 13 between the axially mobile output shaft 11 and the first shaft 12.
    [0027] According to the invention, the mechanical connection device 13 comprises a cup-shaped body 14, in the example shown, delimited by a cylindrical side wall 15 and coupled relatively slidingly to the support 10, parallel to the output shaft 11 and coaxially thereto, by means of at least a pair of lateral guides 16 attached to the support 10 and from which they protrude axially in a cantilever manner towards the cup-shaped body 14 which, according to one aspect of the invention, is fixed to the first shaft 12.
    [0028] The mechanical connection device 13 further comprises a bushing 18 mounted inside the cup-shaped body 14, arranged coaxial to the cup-shaped body 14 and housed relatively slidingly with respect thereto, said bushing 18 being axially integral, in any known manner, to the output shaft 11, so as to move integrally therewith.
    [0029] The side wall 15 of the cup-shaped body 14 is provided at one of its radially internal lateral surfaces 19 (Figure 4), with at least one pair of opposite radial holes 20 (which in the example shown are through holes, but which may also be blind), said radial holes 20 being preferably conical in shape.
    [0030] The lateral surface 19 also cooperates with the bushing 18, in the example shown in contact therewith, and is preferably cylindrically symmetrical.
    [0031] The mechanical connection device 13 further comprises at least one pair of opposite pegs 21 housed so as to slide in respective radial seats 22 of the bushing 18 (Figures 4 and 5) made therein as far as through a radially external lateral wall 23 of the bushing 18.
    [0032] The radial seats 22 also house first springs 24 cooperating with the pegs 21.
    [0033] The springs 24 and the radial seats 22 are configured to make the pegs 21 selectively assume an extracted position (Figure 3) and a retracted position (Figures 6 and 7).
    [0034] In the extracted position of the pegs 21, a first end 25 of the pegs 21 protrudes radially cantilevered from the bushing 18 to engage the radial holes 20 of the cup-shaped body 14 and thus fix the cup-shaped body 14 to the bushing 18.
    [0035] In the retracted position, the first end 25 of the pegs is at least partially housed in a concealed fashion in the radial seats 20 against the action of the first springs 24 so as not to engage the radial holes 20 of the cup-shaped body 14.
    [0036] In order to facilitate the introduction of the pegs 21 into the seats 22 and to prevent their accidental release, the pegs 21 (Figure 5) and seats 20 have bayonet couplings.
    [0037] The mechanical connection device 13 lastly comprises second springs 26, packed between the support 10 and the cup-shaped body 14 and between the support 10 and respective shoulder elements 27 (Figure 5), which are fixed to the cup-shaped body 14 and are arranged, with respect to the support 10, on the side opposite to the cup-shaped body 14.
    [0038] According to another important aspect of the invention, the first ends 25 of the pegs 21 are delimited by respective surfaces 28 (Figure 4) arranged obliquely with respect to an axis of symmetry A of the output shaft 11 and the bushing 18, in the non-limiting example illustrated defined by conical surfaces coaxial with the pegs 21.
    [0039] The oblique (conical) surfaces 28 are configured to cooperate with a perimeter edge 29 (Figure 4), also conical in the non-limiting example shown, of the radial holes 20 to push the pegs 21 towards the retracted position, against the action of the first springs 24, as a result of any axial stress F (Figures 6 and 7) applied in use to the first shaft 12 and exceeding a pre-set threshold value, for example calculated during the design phase, so that in the retracted position of the pegs 21 the bushing 18 is no longer axially constrained to the cup-shaped body 14 and is consequently free to move axially with respect to the cup-shaped body 14. For the same reason, the support 10 is also free to move in relation to the cup-shaped body 14 against the action of the springs 26, together (but not necessarily of the same magnitude) with the bushing 18.
    [0040] The mechanical connection device 13 further comprises a second shaft 29 configured to couple integrally, on one side, with the output shaft 11 of the first component 7 and, on the other side, with the bushing 18.
    [0041] According to one aspect of the invention, the shaft 29 is connected to the bushing 18 by a ball joint 30, preferably designed to allow a snap connection with the shaft 29.
    [0042] According to a preferred embodiment of the invention, the bushing 18 comprises: an annular or cup-shaped drum 31, preferably cylindrical, which has a first end 32 facing the first shaft 12 and provided with radial seats 22 for the pegs 21 and the springs 24; a cover 33 for closing a second end 34 of the drum 31, opposite the end 32 and open towards the support 10; and a spherical joint 35 (Figure 5), which fixedly receives the output shaft 11 and cooperates in contact with a first inner lateral surface 36 of the drum 31.
    [0043] The cover 33 is provided with a hole 37 for receiving the output shaft 11 through it as far as into the drum 31 and the spherical joint 35 is axially blocked inside the drum 31 by the cover 33.
    [0044] The output shaft 11 is coupled, according to the preferred embodiment shown by way of a non-limiting example, integral with the second shaft 29, which is arranged coaxial with it and also housed inside the drum 31.
    [0045] The shaft 29 in turn couples to the spherical joint 35 radially inside thereof by means of the ball joint 30, which comprises a spherical head 38 made in one piece with the shaft 29 at a first end thereof opposite the output shaft 11, and a spherical receiving element 39 for the spherical head 38, made in one piece with the spherical joint 35 and extending axially cantilevered towards the first end 32 of the drum 31, with which it couples in contact with a second inner lateral surface 40 of the drum 31 by means of an outer lateral surface thereof, of a spherical shape.
    [0046] The shaft 12 is preferably made in one piece with the cup-shaped body 14, coaxially with the output shaft 11, and extends axially cantilevered from a bottom wall 41 of the cup-shaped body 14, externally thereto and on the opposite side of the bushing 18.
    [0047] In addition, the shaft 12 is preferably provided at one free end with a spherical joint coupling element 42 to the second component 4 or 3 for receiving stresses from the same.
    [0048] In order to allow an easy, simple and effective assembly and a reliable operation of the springs 26, the support 10 is provided radially cantilevered and radially externally with at least one pair of opposite first lugs 43, each of which is delimited (shown only in Figure 5) by a first face 44 facing the cup-shaped body 14 and by a second face 45 facing the side opposite to the cup-shaped body 14.
    [0049] The faces 44, 45 are provided in an axially cantilevered manner, respectively, with a first pin 46 and a second pin 47, opposite and coaxial.
    [0050] The pins 46, 47 are arranged parallel to the axis of symmetry A of the output shaft 11 and of the bushing 18 and partially supporting cantilevered springs 26, which are helical springs each fitted on a respective first or second pin 46 and 47 and coupled in contact against the first and second faces 44, 45 of the lugs 43.
    [0051] The cup-shaped body 14 is provided at the first lugs 43 of the support 10 with second lugs 48 facing the lugs 43.
    [0052] Respective pairs of straight longerons 49 protrude cantilevered from the lugs 48, parallel to the pins 46, 47 and towards the support 10 (Figure 5).
    [0053] Between each pair of longerons 49 a respective radially outer end 50 of a lug 43 provided with a respective first pin 46 and second pin 47 is axially slidingly inserted, which are also arranged between the pair of longerons 49 together with a pair of second springs 26, each fitted on a first or second pin 46 and 47, respectively.
    [0054] The shoulder elements 27 preferably consist of plates, each snap-coupled to respective free ends 51 of a pair of longerons 50 (Figure 5).
    [0055] The plates 27 and the lugs 48 are preferably provided one towards the other with cantilevered sleeves 52 coaxial with the pins 46, 47 inside which the respective ends of the springs 26 opposite the first lugs 43 are inserted.
    [0056] The sleeves 52 are also configured to cooperate with the radially outer ends 50 of the lugs 43 to serve as axial end stop elements for the support 10 when the pegs 21 are in the retracted position.
    [0057] Preferably, to facilitate assembly, the cup-shaped body 14 is made up of two elements consisting of an annular element 53 coupled frontally to a cup-shaped element 54 and connected integrally together by means of detachable connection members, preferably screws 55.
    [0058] The cup-shaped element 54 is the one with the radial holes 20 and both the annular element 53 and cup-shaped element 54 are coaxial to each other and configured to slidingly receive the bushing 18 inside them.
    [0059] From the description above it is clear that the transmission device 13 is specifically configured to be housed inside a vehicle lighting device 1 to connect an electric motor or actuator 7 with a reflector 4 or light source 3, to vary its orientation.
    [0060] For this purpose, the support 10 is also provided, on the side opposite the lateral guides 16, with a pair of lateral pads 56, configured to support the entire transmission device 13 inside the lighting device 1 and specifically to couple with elements 57, illustrated merely schematically and by dashed lines in Figure 1, of the manual trim adjuster 9.
    [0061] The invention therefore lastly also relates to a vehicle comprising a lighting device 1, headlamp or rear light provided with a transmission device 13 as described, for connecting together an electric motor or actuator 7 with a reflector 4 or light source 3 in order to vary the orientation thereof.
    [0062] Owing to the transmission device 13 as described, it is clear that the lighting device equipped with it is protected from damage not only in the case of jamming of the lighting element, but also in the case of projectors without an external lens as a result of vandalism or in any other case of excessive force applied to the lighting elements.
    [0063] Consequently, all the purposes of the invention are achieved.
