[0002] In the field of mechanical transmission, the motor drive structure is a key device for transmitting the rotational power of the motor to various working components. Traditional motor drive structures often adopt a single transmission method, such as using multi-stage cylindrical spur gears to achieve the transmission of motor power. This power transmission method generates relatively high noise during operation. In addition, the multi-stage reduction cylindrical spur gears also occupy a relatively large space.

[0003] Based on this, this application aims to reduce the noise generated by motor transmission.

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of the present application.

[0026] In the embodiments of the present application, please refer to Figures 1-4 As shown, a motor drive structure mainly includes: a motor 1, a motor shaft 2, a first transmission shaft 3, a second transmission shaft 4, and a reduction gear set 5; a worm 6 is provided on the motor shaft 2, a worm gear 7 and a first bevel gear 8 are installed on the first transmission shaft 3, the first transmission shaft 3 is substantially perpendicular to the motor shaft 2, and the worm 6 is engaged with the worm gear 7; the second transmission shaft 4 is arranged parallel to one side of the motor shaft 2, a second bevel gear 9 and a transmission gear 10 are installed on the second transmission shaft 4, the second bevel gear 9 is engaged with the first bevel gear 8, and the transmission gear 10 is connected to the reduction gear set 5.

[0027] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0028] As Figures 2-3 shown, the motor drive structure is installed in a gearbox, the gearbox includes a cover plate 11 and a box body 12, two support plates arranged at intervals are provided on the cover plate 11, the first transmission shaft 3 is installed on the two support plates, the worm gear 7 and the first bevel gear 8 are placed between the two support plates, and the two support plates are respectively a first support plate 13 and a second support plate 14, realizing the installation of the worm gear 7 and the first bevel gear 8, and making the drive structure relatively compact.

[0029] Specifically, the first support plate 13 and the second support plate 14 are arranged on both sides of the worm 6, which can make the arranged structure relatively compact.

[0030] As Figure 4 shown, the second support plate 14 is detachably connected to the cover plate 11. A first fixing position 1301 for pre-fixing the first transmission shaft 3 is provided on the first support plate 13. Specifically, two support columns 16 are provided on the cover plate 11, and the second support plate 14 is detachably fixed to the support columns 16 by two screws. With this arrangement, after the first transmission shaft 3 is pre-fixed at the first fixing position 1301 on the first support plate 13, the second support plate 14 can be installed to realize the limit of both ends of the first transmission shaft 3. The detachable design of the second support plate 14 facilitates the disassembly, assembly and maintenance of the first transmission shaft 3, the worm wheel 7 and the first bevel gear 8.

[0031] Furthermore, a second fixing position (not shown in the figure) is provided on the inner wall of the box body 12 relative to the cover plate 11 for pre-fixing one end of the second transmission shaft 4. The purpose of this arrangement is that due to the presence of the second support plate 14, there is already a lack of good space on the cover plate 11 to realize the pre-pressing of the second transmission shaft 4. In order to maintain the overall compactness of the structure, the pre-pressing second fixing position is set at the corresponding position of the box body 12.

[0032] As Figure 1 shown, taking the cover plate 11 as the horizontal reference, the second bevel gear 9 is higher than the height of the second support plate 14 close to the second transmission shaft 4, so as to make the structure more compact.

[0033] Furthermore, the reduction gear set 5 includes a first reduction gear 501 and a second reduction gear 502 that mesh with each other. The first reduction gear 501 is arranged in parallel with and remains meshed with the transmission gear 10. The second reduction gear 502 drives the output end 15 to rotate. In the above embodiment, the reduction gear set 5 is a two-stage reduction. In some other implementation cases, the reduction gear set 5 can also be a single-stage reduction or a multi-stage reduction, and can be adaptively modified according to actual use, which will not be limited in this application.

[0034] In one embodiment, the worm wheel 7 and the first bevel gear 8 are of an integral structure or a split structure; and the second bevel gear 9 and the transmission gear 10 are of an integral structure or a split structure.

[0035] In one embodiment, the worm wheel 7 and the first bevel gear 8 are a composite gear of an integral structure, so that the overall transmission structure is good.

[0036] In one embodiment, the second bevel gear 9 and the transmission gear 10 are a composite gear of an integral structure, so that the overall transmission structure is good.

To avoid obscuring the concept of the present application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present application. The foregoing embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
