[0015] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1-5 As shown, the embodiment of the utility model includes:

[0017] A motor axial fixing structure of an automobile shift actuator 100 includes a housing 1, a spacer 2, a positioning groove 3, a motor 4, a positioning journal 5, and an axial spring 6. The housing 1 has a pair of spacers 2 built in, the spacers 2 are provided with positioning grooves 3, the motor 4 is accommodated between the spacers 2, positioning journals 5 are provided at both ends of the motor 4, the positioning journals 5 are matched on the positioning grooves 3, and an axial spring 6 is inserted between the rear end face of the motor 4 and the spacer 2.

[0018] The axial spring 6 is composed of an integrally formed insert 7 and a spring 8. The insert 7 is provided with a U-shaped notch 9 matching the positioning journal 5. A plurality of outwardly folded springs 8 are cut on both sides of the U-shaped notch 9. The spring 8 elastically abuts against the spacer 2.

[0019] Furthermore, the positioning groove 3 is supported on the lower part of the positioning journal 5 , and the U-shaped notch 9 is pressed on the upper part of the positioning journal 5 . The positioning groove 3 and the U-shaped notch 9 surround the positioning journal 5 .

[0020] Furthermore, the insert 7 covers the entire rear end surface of the motor 4 .

[0021] When the motor 4 vibrates during operation, the reed 8 absorbs the vibration from the motor 4 through elastic deformation. On the other hand, the reed 8 elastically abuts against the spacer 2 obliquely upward, and the spacer 2 generates an oblique downward force on the reed 8, thereby suppressing radial and axial vibrations. In addition, the positioning groove 3 and the U-shaped notch 9 press the two end journals of the motor 4, further improving the stability of the motor 4.

[0022] In summary, the utility model provides an axial fixing structure of the motor 4 of the automobile shift actuator 100. The motor 4 is fixed by the axial spring 6 to provide elastic holding force. It can still provide sufficient holding force under high temperature and high vibration conditions, so that the motor 4 can work smoothly, reduce noise and increase service life.

[0023] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
