[0010] Since the rear cover in the prior art has no structure for supporting the rotor, additional parts need to be added to realize support, so as to support the bearing and further realize high integration and reduce the number of parts, the center of the inner side wall of the rear cover body is provided with an integrally formed bearing seat.

[0011] In order to reinforce and strengthen the bearing seat, a plurality of integrally formed ribs are uniformly distributed in the circumferential direction of the outer side wall of the bearing seat. Among them, a plurality of ribs are used to increase the strength of the bearing seat, and the height of the ribs is lower than the mounting surface of the PCBA plate.

Using the same or similar material for both the motor body and the back cover allows welding to replace traditional sealing and riveting / gluing processes, achieving effective fixation and sealing. This simplifies the structure of the back cover and the housing, avoids the use of sealing rings / sealing adhesives, reduces costs, and also reduces radial space, enabling product miniaturization.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0033] Example:

[0034] In existing technologies, such as Figure 1 As shown, when assembling the motor with the rear cover, components such as the rear cover sealing film 7 and the rear cover sealing ring 8 need to be installed at the rear cover, and the position of the connector 2 is fixed. Furthermore, the rear cover does not have a structure to support the rotor and fix the PCBAA, so additional parts need to be added to achieve support. The rear cover and the housing are fixed by bolts, resulting in a large number of parts, a more complex assembly process, and higher costs. In addition, the fixed position of the connector 2 means that the interface position cannot be adjusted according to the position of the external control equipment.

[0035] In contrast to the problems in the prior art, this embodiment provides a highly integrated motor rear cover structure, such as...Figures 2-5 As shown, it includes:

[0036] The rear cover body 1 has a connector 2 on its outer side wall, which is used to connect to an external control device through an interface.

[0037] The back cover body 1 and the connector 2 are integrally formed.

[0038] Compared to existing technologies where the back cover and connector 2 are separate structures requiring sealing rings or adhesives, along with bolts for sealing and fixing during installation, resulting in a large number of parts, complex assembly processes, and high costs; furthermore, the fixed position of connector 2 prevents adjustment of the interface position based on the location of external control equipment and increases the issue of radial dimensions. This invention provides a highly integrated motor back cover structure. This solution combines connector 2 and the back cover through integrated molding, improving assembly efficiency and effectively reducing costs. Moreover, thanks to the integrated injection molding process, the extension direction of connector 2 can be flexibly adjusted to meet different interface requirements. Specifically, the back cover body 1 and connector 2 are integrated using a combination of stamping and injection molding processes. This eliminates the need for sealing rings or adhesives during installation, improving motor assembly efficiency. Additionally, during the actual stamping and injection molding process, the exit direction of connector 2 terminals can be flexibly adjusted according to interface requirements. Connector 2 can be positioned at any location on the outer wall of the back cover body 1, enabling product miniaturization.

[0039] Since the existing technology does not support the rotor structure of the rear cover, additional parts are needed to achieve support. Therefore, in order to support the bearing and further achieve high integration and reduce the number of parts, an integrally formed bearing seat 3 is provided at the center of the inner side wall of the rear cover body 1.

[0040] To reinforce the bearing housing 3, several integrally formed ribs 301 are evenly distributed in the circumferential direction on the outer side wall of the bearing housing 3. Some of these ribs are used to increase the strength of the bearing housing, and their height is lower than the mounting surface of the PCBA board.

[0041] During installation, to position and guide the PCBA board 5, several integrally formed guide fixing posts 4 are provided on the inner side wall of the rear cover body 1. The guide fixing posts 4 are used to pass through the mounting holes on the PCBA board 5. The guide fixing posts 4 can pass through the mounting holes on the PCBA board 5 and can then be fixed by welding.

[0042] As a redundancy scheme, several of the guide fixing posts 4 are distributed in the circumferential position of the bearing seat 3.

[0043] To support the PCBA board 5 and further achieve high integration and reduce the number of parts, an integrally formed support strip 6 is also provided on the inner side wall of the back cover body 1. The height of the support strip 6 is flush with the installation height of the PCBA board 5.

[0044] As a redundancy solution, there are several support bars 6, which are located on one side of the bearing seat 3 or distributed on both sides.

[0045] Furthermore, this solution also provides a motor, including a motor body and a rear cover mounted on the motor body, wherein the motor body and the rear cover are both made of the same material.

[0046] In existing technologies, the connection between the back cover and the motor body is typically achieved through sealing and riveting / gluing processes, which are complex and costly. Therefore, to achieve effective fixation and sealing, both the motor body and the back cover are made of the same material; the motor body and the back cover are connected by welding. Using the same or similar material for both the motor body and the back cover allows welding to replace traditional sealing and riveting / gluing processes, achieving effective fixation and sealing. This simplifies the structure of the back cover and the housing, avoids the use of sealing rings / sealing adhesives, reduces costs, and also reduces radial space, enabling product miniaturization.

[0047] Since the existing technology does not have a structure for fixing the PCBA board 5 in the back cover, a PCBA board 5 is also included to support the PCBA board 5 and further achieve high integration and reduce the number of parts. The PCBA board 5 is used to install on the inner side wall of the back cover. The inner side wall of the back cover has several integrally formed support structures, each with a flush support surface for supporting the PCBA board 5. The support structure includes several support strips 6.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
