    Please refer to FIG. 1 and FIG. 2, which are a perspective explosion view and a perspective assembly view according to the present invention, respectively. The present invention provides a linear transmission cylinder and its driving motor. The linear transmission cylinder comprises a case 1. The driving motor includes a stator 2 and a rotor 3.
    The case 1 constitutes an enclosure of the linear transmission cylinder. The case! includes a lower component 10 and an upper component 11. The lower component 10 covers the upper component 11 such that the case 1 is hollow. The lower component 10 includes a telescopic rod housing 12 extending therefrom to carry other components of the linear transmission cylinder (such as, a lead screw, a worm gear a worm wheel and a deceleration gear set linked to the lead screw). The detailed structure of the telescopic rod housing 12 is not described herein.
    The stator 2 and the rotor 3 are disposed inside the lower component 10 and the upper component 11, and the stator 2 is disposed outside the rotor 3. In the embodiment of the present invention, the stator 2 includes a hollow sleeve 20 and a plurality. of magnetic elements 21 disposed on an internal wall of the sleeve 20. The rotor 3 includes a rotary shaft 30 and an induction coil 31 disposed on the rotary shaft 30. The induction coil 31 is located inside the sleeve 20 of the stator 2 and generates electromagnetic induction with respect to the magnetic element 21. Two brush holders 13 are disposed on two sides of the lower component 10 so as to correspond to two sides of the rotary shaft 30. A brush 130 is disposed inside the brush holder 13 so as to electrically contact the rotary 'shaft 30, such that the driving motor is constructed.
    Please also refer to FIG. 3. In the present invention, structures for positioning and limiting the stator 10 and the rotor 11 are disposed on internal walls of the lower component over the upper component 11 of the case 1, such that in the condition of the elimination of an enclosure material. of the driving motor, the lower component 10 and the upper component 11 of the case 1 can be shrunk. Specifically, a plurality of lower ribs 100 in an interval arrangement protrudes from the internal wall of the lower component 10, so as to abut an external wall of the stator 10. A plurality of upper ribs 110 in interval arrangement protrudes from the internal wall of the upper component 11, so as to abut the external wall of the stator 10. Accordingly, the upper rib 110 and the lower rib 100 can render the upper component 11 and the lower component 10 closely abutted to the stator 10 so as to position or limit the driving motor. A concave lower shaft nest 101 is formed on a rear interior wall of the lower component 10, and a concave upper shaft nest 111 is formed on a rear interior wall of the upper component 11. A rear end of the rotary shaft 30 of the rotor 3 is supported inside the upper shaft nest 111 and the lower shaft nest 101. A lower shaft base 102 is formed on a front interior wall of the lower component 10, and an upper shaft base 112 is formed on a front interior wall of the upper component 11. A front end of the rotary shaft 30 of the rotor 3 is pivoted on the upper shaft base 112 and the lower shaft base 102. Accordingly, after the enclosure material of the driving motor is eliminated, the upper component 11 and the lower component 10 of the case 1 can directly position and limit the stator 2 and the rotary shaft 30 of the rotor 3 of the driving motor, such that the case l can be further shrunk. The present invention can achieve advantages of fewer parts, lower cost and simpler assembly.
    In addition, as illustrated in FIG. 4, in the present invention, a resilient element 131 is disposed within the brush holder 13. The resilient element 131 biases the brush 130 to abut toward the rotary shaft 30, such as to maintain electrical contact between the brush 130 and the rotary shaft 30 Further, the lower shaft nest 101 and the lower shaft base 102 of the lower component 10 can be assembled on the internal wall of the lower component 10 in a detachable method. The detachable method can, for instance, be a concave and convex interference fit method.
    Accordingly, the above-mentioned construction achieves the linear transmission cylinder and its driving engine of the present invention.
    Specifically, in the linear transmission cylinder and its driving motor of the present invention, the driving motor is covered by and directly disposed within the case of the linear transmission cylinder which can provide positioning and limiting, so as to eliminate the enclosure material of the driving motor, thus shrinking the entire structure.
