Description

Technical Field

[0001] The utility model relates to the technical field of speed reduction mechanisms, in particular to an installation structure of a motor and a speed reduction box. Background Art

[0002] See also Figure 1 The reduction mechanism shown in the figure includes a motor 1 and a reduction box body 2. The housing of the motor 1 is connected and installed with screws to the screw mounting holes of the reduction box body 2. This will result in a larger motor volume, affect the size design of the reduction box body 2, and cause unnecessary interference to the installation of the seat frame. Utility Model Content

[0003] The technical problem to be solved by the present utility model is to provide a motor and reduction box installation structure with a compact structure, which reduces the size of the motor and effectively reduces the interference problem of the original protruding screw holes during the installation process, in order to address the problem that the use of screws to install the motor and the reduction box in the existing reduction mechanism will affect the size design of the reduction box 2 and cause unnecessary interference with the installation of the seat frame.

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

[0005] A motor and reduction box installation structure comprises a motor and a reduction box body, wherein a plurality of protruding rivet claws are punched out at positions of the motor casing for installing the reduction box body, the reduction box body is formed by plastic injection molding, and a slot is arranged at a position of the reduction box body corresponding to each protruding rivet claw, and the protruding rivet claws are bent and riveted to the reduction box body after passing through the slots.

[0006] In a preferred embodiment of the present invention, a flattening position is added at the bending portion of the raised rivet claw to facilitate assembly and riveting during production.

[0007] In a preferred embodiment of the utility model, the number of the raised rivet claws is four or more, which are circumferentially arranged on the housing of the motor for installing the reduction gear box, and the number of the slots is also four or more, which are circumferentially arranged on the reduction gear box.

[0008] Due to the adoption of the above technical solution, the utility model eliminates the mounting screw holes of the motor casing and the reduction box body through structural optimization, and adds four (or more) raised rivet claws for fixing the single motor and the reduction box body, so as to make the structure compact, reduce the volume of the motor, and effectively reduce the possibility of interference of the original protruding screw holes during the installation process. At the same time, the elimination of the screws reduces the production cost of the reduction mechanism to a certain extent, simplifies the motor installation steps, and directly improves the production capacity of the reduction mechanism.

[0012] See also Figures 2 to 3 The motor and reduction box installation structure shown in the figure includes a motor 10 and a reduction box body 20. A plurality of protruding rivet claws 12 (four or more) are punched at the position of the housing 11 of the motor 10 for installing the reduction box body 20. The plurality of protruding rivet claws 12 are circumferentially arranged on the housing 11 of the motor 10. The reduction box body 20 is formed by plastic injection molding. A slot 21 is provided at the position of the reduction box body 20 corresponding to each protruding rivet claw 12. The number of the slots 21 is also four or more and circumferentially arranged on the reduction box body 20. The protruding rivet claws 12 pass through the slots 21 and are bent and riveted to the reduction box body 20. A flattening position 13 is added at the bending part of each protruding rivet claw 12 to facilitate assembly and riveting in production. During assembly, a matching slot 21 is injection-molded on the reduction box body 20 to ensure the concentricity of the raised rivet claw 12 of the casing 11 and the slot 21 on the reduction box body 20. After aligning the center, the raised rivet claw 12 on the casing 11 of the motor 10 is inserted into the slot 21 of the reduction box body 20, and then the reduction box body 20 is rotated to align the raised rivet claw 12 on the casing 11 of the motor 10 with the slot 21 on the reduction box body 20. A riveting machine is used to rivet the raised rivet claw 12 in turn to fix the motor 10 and the reduction box body 20. While achieving the same effect as screw connection, it reduces some installation components, simplifies the installation steps, and improves the efficiency of motor assembly.

[0013] The motor casing of the utility model is formed by stamping, and the cumbersome flanging and punching processes of metal parts are reduced, and four (or more) raised rivet claws 12 are replaced, which are aligned and installed with the connection of the slot 21 of the reduction box body 20. The four (or more) raised rivet claws 12 are respectively riveted to the slot 21 of the reduction box body 20 and fixed to the reduction box body 20, thereby ensuring the strength of the connection while better controlling the size of the motor and reducing the cost.
