DETAILED DESCRIPTION

[0031] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0032] Reference Figures 1-4The easy-to-install automobile seat gear box provided by the embodiment of the application comprises a box body 100, a box cover 200, and a worm wheel 320 and a worm gear 310 installed in the box body 100, wherein the worm wheel 320 and the worm gear 310 are connected, and it is to be noted that a slide rail is arranged below the seat of the automobile, and a lead screw 900 is installed on the bottom plate below the seat in the moving direction of the automobile seat. For the gear box provided by the embodiment of the application, the worm gear 310 needs to be driven by an external motor, and the worm wheel 320 is threadedly connected with the lead screw 900. In addition, the gear box provided by the embodiment of the application further comprises a plurality of bolts 400, a plurality of threaded holes 110 are formed in the box body 100, a plurality of through holes 210 corresponding to the threaded holes 110 are formed in the box cover 200, the bolts 400 are threadedly connected in the threaded holes 110 of the box body 100 after passing through the through holes 210 of the box cover 200; an adjusting member 500 for synchronously tightening or loosening all the bolts 400 is installed on the box cover 200; the adjusting member 500 comprises a mounting column 510 fixed on the side of the box cover 200 away from the box body 100, a connecting ring 520 rotatably connected to the outer periphery of the mounting column 510, a driving gear ring 530 coaxially fixed to the outer periphery of the connecting ring 520, and a driven gear 540 fixedly connected to the nut part of the bolt 400, and the driven gear 540 is in meshing connection with the driving gear.

[0033] Further, referring to Figure 3 , in order to make the force of the driven gear 540 on the driving gear ring 530 more uniform, all the bolts 400 are distributed in a circumferential array about the axis of the mounting column 510.

[0034] Further, referring to Figure 3 , a plurality of control rods 550 are fixed to the connecting ring 520.

[0035] Further introduction is made in combination with a specific use scenario as follows. During installation, the bolts 400 on the box cover 200 are aligned with the threaded holes 110 of the box body 100, then the connecting ring 520 is rotated about the axis of the mounting column 510 by rotating the control rod 550, and all the bolts 400 are synchronously rotated by the meshing between the driving gear ring 530 and the driven gear 540, so as to be screwed into the threaded holes 110 synchronously, until the box cover 200 and the box body 100 are completely attached. Similarly, when the gear box needs to be disassembled, the connecting ring 520 is reversely rotated by the control rod 550, and all the bolts 400 are synchronously unscrewed from the threaded holes 110 under the meshing between the driving gear and the driven gear 540, so as to realize the disassembly of the box cover 200 and the box body 100, and no other tools are needed, which improves the disassembly convenience and efficiency of the gear box.

[0036] The application sets the adjusting piece 500 on the box cover 200, controls the rotation of the driving gear ring 530 by controlling the rotation of the connecting ring 520, and then drives all the bolts 400 to rotate synchronously by the cooperation of the driving gear ring 530 and the driven gear 540, so that the tightening or loosening operation of all the bolts 400 can be quickly realized, and the multiple connecting bolts 400 between the box body 100 and the box cover 200 can be tightened or loosened at one time without tools, which improves the disassembly convenience and efficiency of the gear box.

[0037] With reference to Figure 3 and Figure 4 The bearing 700 is installed at the through hole 210 of the box cover 200, and the inner ring of the bearing 700 is fixedly connected with the bolt 400.

[0038] In combination with a specific use scenario, the bearing 700 can ensure that the bolt 400 and the box cover 200 can be synchronously close to the box body 100 during installation, so that when the bolt 400 is completely separated from the box body 100 during disassembly, the box cover 200 is just disassembled, and the box cover 200 and the box body 100 do not need to be separated again (i.e., the step of taking the box cover 200 off the box body 100), which improves the separation speed of the box body 100 and the box cover 200 to a certain extent.

[0039] With reference to Figure 4 As a specific embodiment of the application, a plurality of blind holes 120 are formed on the side of the box body 100 close to the box cover 200, and springs 610 are installed in the blind holes 120.

[0040] Further, the abutting column 620 is fixedly connected to the end of the spring 610.

[0041] In combination with a specific use scenario, the spring 610 can exert a force away from the box body 100 on the box cover 200 when the gear box is disassembled, which facilitates the separation of the box body 100 and the box cover 200.

[0042] With reference to Figure 2 and Figure 3 As a specific embodiment of the application, a dust cover 800 is installed on the side of the box cover 200 away from the box body 100.

[0043] In combination with a specific use scenario, the dust cover 800 can be installed to reduce dust or debris under the seat from entering the meshing surface of the driving gear ring 530 and the driven gear 540, reduce the friction of the tooth surface, avoid affecting the meshing of the driving gear ring 530 and the driven gear 540, improve the stability of the meshing of the driving gear ring 530 and the driven gear 540, and further improve the stability of the seat adjustment. It should be understood that various forms of processes shown above can be used to reorder, add or delete steps. For example, each step described in the present application can be executed in parallel, sequentially or in a different order, as long as the desired results of the technical solutions of the present application can be achieved, and the present application is not limited herein.

[0044] In addition, the terms "first", "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features.
