According to the utility model, the motor mounting point is transferred to the reduction gearbox body from the reduction gearbox cover, and the stress point of the motor is transferred to the reduction gearbox body from the reduction gearbox cover, so that the bearing capacity and the tensile strength of the motor can be effectively increased, and the use requirements of more passenger vehicles can be met.

Description

Technical Field

[0001] The utility model relates to the technical field of headrest motors, in particular to a high-strength speed reduction headrest motor. Background Art

[0002] See also Figure 1 The conventional headrest motors are fixedly connected to the frame through three screw mounting holes 2 on the reduction box cover 1. Since the reduction box body 3 and the reduction box cover 1 are both plastic parts, there is a risk of the screws loosening or slipping during assembly or use. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a high-strength reduction headrest motor in response to the above-mentioned deficiencies in the prior art, which transfers the motor's slot force point from the reduction box cover to the reduction box body, which can effectively increase the tensile strength of the motor and increase the service life of the motor.

[0004] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0005] A high-strength reduction headrest motor comprises a motor and a reduction box, wherein the reduction box comprises a reduction box body and a reduction box cover, and is characterized in that at least two clamping blocks of the reduction box cover extend from the reduction box body and a screw mounting hole protruding from the reduction box cover is provided on the reduction box body; during installation, each clamping block is inserted into each clamping slot on a skeleton mounting plate, and a screw passes through the screw mounting hole on the reduction box body and is screwed into the bolt hole of the skeleton mounting plate.

[0006] In a preferred embodiment of the present invention, the cross section of the clamping block is V-shaped.

[0007] Due to the adoption of the above technical solution, the installation and fixing point of the motor of the utility model adopts a block structure. By hanging the block in the slot of the frame mounting plate, the motor can be prevented from being separated or loosened during operation. The reduction box body and the frame are locked and fixed by a screw, which can prevent the motor from being displaced during durability and operation. The motor installation point of the utility model is transferred from the reduction box cover to the reduction box body, and the force point of the motor is transferred from the reduction box cover to the reduction box body, which can effectively increase the bearing capacity and tensile strength of the motor and meet the use requirements of more passenger cars.

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.

[0014] See also Figure 2 and Figure 5 A high-strength reduction headrest motor shown in the figure includes a motor 10 and a reduction box 20. The reduction box 20 includes a reduction box body 21 and a reduction box cover 22. Two blocks 21a (of course not limited to two) of the reduction box cover 22 extend from the reduction box body 21, and a screw mounting hole 21b protruding from the reduction box cover 22 is provided on the reduction box body 21; the cross-section of the block 21a is V-shaped, which can reduce the gap between the high-strength reduction headrest motor and the frame after assembly and reduce axial stringing.

[0015] During installation, each clamping block 21 a is inserted into each clamping slot 31 on the frame mounting plate 30 , and a screw passes through the screw mounting hole 21 b on the reduction box body 21 and is screwed into the bolt hole 32 of the frame mounting plate 30 .

Claims
