The box body and the upper cover are bonded by glue and the sealing portion is locked by screws to achieve sealing of the motor.

[0004] However, since the above solution requires an additional process of gluing in the production line when assembling the motor, the production and processing efficiency of the motor seal assembly is low. Utility Model Content

[0005] The purpose of the present application is to provide a motor and a vehicle, which are used to solve the problem of low production and processing efficiency during motor seal assembly caused by the motor seal assembly process.

[0006] In order to achieve the above purpose, the technical solution adopted in this application is as follows:

The sealing member is located between the box cover and the motor housing, and is arranged around the circumference of the box cover, and is located at the periphery of the terminal box opening. The sealing member is connected to the box cover.

[0008] According to the above technical means, the seal can seal the motor housing and the box cover. Since the seal and the box cover are directly connected as a whole during production and processing, there is no need to add an additional process of installing the seal during the sealing assembly of the production line, thereby improving the production and processing efficiency of the motor sealing assembly.

[0009] In a possible implementation manner, the motor further comprises an adhesive member, which is located between the sealing member and the box cover and is bonded to the sealing member and the box cover, wherein the box cover and the sealing member are connected via the adhesive member.

[0044] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0046] In recent years, with the development of vehicle electrification, the market share of new energy electric vehicles has continued to increase. The motor is an important component of new energy electric vehicles, so there are high requirements for the protection of the motor. On the one hand, the motor may be intruded by water and cause failure, and this water may come from rainwater, road water or car wash water. On the other hand, the motor may be intruded by oil and cause failure, and this oil may come from the lubricating oil of other parts in the vehicle. Therefore, the motor is often provided with a sealing structure at the cover of the motor to isolate the intrusion of water and oil. In addition, the sealing structure needs to be installed reliably, efficiently, and at a low cost.

[0047] The traditional sealing structure is to set a separate sealing ring at the sealing position, or apply sealant at the cover position of the cover. The above scheme can be installed or glued manually, or installed or glued by machine. However, the above schemes all require a separate process on the production line for installing the sealing ring or glueing. This slows down the production rhythm of the production line and leads to low production and processing efficiency during motor seal assembly.

[0048] To solve the problem of low production and processing efficiency during motor seal assembly caused by the seal assembly process. The embodiment of the present application provides a vehicle, which is an electric vehicle. To achieve the basic functions of the vehicle, the vehicle may include components such as a body, a chassis, a power system, and an electrical system.

[0049] The vehicle body may include a vehicle frame, vehicle doors, and vehicle windows. The vehicle frame may form the overall shape of the vehicle exterior and form a seating space for accommodating passengers. The vehicle doors may be rotatably connected to the vehicle frame and may open or close the interior passenger space. The vehicle windows may be installed on the vehicle doors or the vehicle frame to facilitate passengers to observe the external environment.

[0050] The chassis may include components such as a transmission system and a drive system. The drive system can drive the wheels to rotate. Depending on the drive mode of the drive system, the drive system can be divided into front-wheel drive, rear-wheel drive, and four-wheel drive arrangements. The transmission system can transmit the power generated by the power system to the wheels.

[0051] The power system can provide power for the vehicle so that the vehicle can complete basic driving functions. The power system includes a motor.

[0052] In order to supply power to electrical components such as motors, the vehicle provided in the embodiment of the present application further includes a battery system. The battery system may include a battery pack, which may be used to provide electrical energy. The battery pack may be electrically connected to the electrical components of the vehicle. In this way, the electrical energy of the battery pack may be transferred to the electrical components of the vehicle for power supply.

[0053] like Figure 1 As shown, Figure 1 A schematic diagram of the structure of a motor 100 provided in an embodiment of the present application, the motor 100 includes a motor housing 3. The motor housing 3 is used to place a drive assembly, and the drive assembly is used to drive a vehicle. In addition, the motor housing 3 can also protect the drive assembly. In order to facilitate technicians to install or repair the electrical circuits in the motor 100, the motor housing 3 has a junction box opening 31. The connection harness interface end inside the drive assembly in the motor 100 is placed in the junction box opening 31.

[0054] The motor 100 further includes a box cover 1 and a sealing member 12. The box cover 1 is connected to the motor housing 3, and is disposed at the junction box opening 31 and covers the junction box opening 31. The sealing member 12 is located between the box cover 1 and the motor housing 3, and is disposed around the circumference of the box cover 1, and is located at the periphery of the junction box opening 31. The sealing member 12 is connected to the box cover 1.

[0055] In this way, the seal 12 can seal the motor housing 3 and the box cover 1. Figure 2 As shown, Figure 2 A partial structural schematic diagram of a motor 100 provided in an embodiment of the present application, since the seal 12 and the box cover 1 are directly connected as a whole during production and processing, and there is no need to add an additional step of installing the seal 12 during the sealing assembly on the production line, the production and processing efficiency of the motor sealing assembly is improved.

[0056] It is understandable that the connection between the sealing member 12 and the box cover 1 can be in various forms, as long as the sealing member 12 and the box cover 1 can be connected as a whole through this connection form.

[0057] In some possible implementations, such as Figure 3 As shown, Figure 3 The diagram is a partial structural diagram of a motor 100 provided in an embodiment of the present application. The connection between the seal 12 and the box cover 1 is a detachable connection. In this way, the seal 12 and the box cover 1 can be disassembled and assembled, which facilitates the maintenance and replacement of the seal 12 or the box cover 1 separately.

[0058] In some embodiments, the sealing member 12 and the box cover 1 can be snap-fitted, so that the sealing member 12 and the box cover 1 can be assembled and disassembled more quickly and conveniently.

[0059] In a possible implementation, Figure 4 As shown, Figure 4 This is a partial cross-sectional view of a motor 100 provided in an embodiment of the present application, wherein a first clamping portion 4 is formed on the seal 12. A second clamping portion 5 is formed on the side of the box cover 1 close to the seal 12. The first clamping portion 4 is clamped with the second clamping portion 5. In this way, a detachable connection between the seal 12 and the box cover 1 can be achieved, and no tools are required during the disassembly process, making the disassembly and assembly simple and quick.

[0060] In a possible implementation, Figure 5 As shown, Figure 5This is a partial cross-sectional view of a motor 100 provided in an embodiment of the present application, wherein the first clamping portion 4 is a clamping groove, and the second clamping portion 5 is a clamping protrusion. The clamping protrusion is located in the clamping groove and is clamped with the clamping groove. In this way, the clamping protrusion can be restricted in the clamping groove by designing the shape of the clamping groove, and the degree of freedom of the clamping protrusion is restricted by the clamping groove, so that the clamping protrusion is not easy to fall out, thereby ensuring the stability of the connection, so that the seal 12 and the box cover 1 are connected as a whole, and can transmit force to each other.

[0061] In a possible implementation, Figure 6 As shown, Figure 6 A partial cross-sectional view of a motor 100 provided in an embodiment of the present application. The second clamping portion 5 is a clamping groove, and the first clamping portion 4 is a clamping protrusion. The clamping protrusion is located in the clamping groove and is clamped with the clamping groove. In this way, by changing the setting positions of the clamping groove and the clamping protrusion, the diversity of the connection method is increased, and the sealing member 12 and the box cover 1 can also be connected as a whole, and can transmit force to each other.

[0062] In a possible implementation, Figure 5 As shown, the groove wall of the clamping groove forms a limiting groove 121. The clamping protrusion includes a first clamping protrusion 122 and a second clamping protrusion 123. The first clamping protrusion 122 is located in the clamping groove. The second clamping protrusion 123 is located on the peripheral wall of the first clamping protrusion 122 and is connected to the first clamping protrusion 122. The second clamping protrusion 123 is located in the limiting groove 121. In this way, the freedom of the second clamping protrusion 123 located in the limiting groove 121 along the installation direction is limited by the limiting groove 121, so that the sealing member 12 and the box cover 1 are connected as a whole, and can transmit force to each other.

[0063] In a possible implementation, Figure 5 As shown, the surface of the second clamping protrusion 123 on the side close to the bottom of the clamping groove is an inclined surface 1221. The inclined surface 1221 has a first end 12211 and a second end 12212. The first end 12211 is connected to the first clamping protrusion 122, and the second end 12212 is away from the first clamping protrusion 122 and is located on the side of the first end 12211 away from the bottom of the clamping groove. In this way, the inclined surface 1221 can guide the installation of the clamping protrusion into the clamping groove, so that the clamping protrusion can be installed in the clamping groove more easily.

[0064] In some other possible implementations, the surface of the second engaging protrusion 123 on one side close to the bottom of the engaging groove may not be an inclined surface, so as to reduce the difficulty of processing the engaging protrusion.

[0065] In some possible implementations, the seal 12 can be made of a material with a certain degree of deformation ability, such as rubber, silicone, etc. In this way, the seal 12 can fill the small gap between the box cover 1 and the motor housing 3, achieving a better sealing effect.

[0066] Based on the above embodiments, the above clamping method can add an interference fit at the corresponding clamping position on the basis of the clamping, so as to obtain better sealing between the sealing member 12 and the box cover 1.

[0067] In a possible implementation, the connection between the sealing member 12 and the box cover 1 is a fixed connection, such as bonding, so that the connection can withstand greater forces and torques, making the connection more stable and having better sealing properties.

[0068] In a possible implementation, the motor 100 further includes an adhesive member, which is located between the seal 12 and the box cover 1 and is bonded to the seal 12 and the box cover 1. The box cover 1 and the seal 12 are connected via the adhesive member. In this way, a fixed connection between the seal 12 and the box cover 1 can be achieved, and a more stable connection can be obtained.

[0069] In a possible implementation, the adhesive member is arranged around the circumference of the sealing member 12. In this way, it can be ensured that the sealing member 12 can be completely bonded to the box cover 1.

[0070] In a possible implementation, the adhesive is a pressure-sensitive adhesive, such as a polyurethane pressure-sensitive adhesive. Thus, the sealing member 12 and the box cover 1 are bonded together by applying pressure to the adhesive, so that the sealing member 12 and the box cover 1 form a whole.

[0071] In a possible implementation, the adhesive is a heat-sensitive adhesive, such as epoxy resin adhesive. Thus, the sealing member 12 and the box cover 1 are bonded together by heating the adhesive, so that the sealing member 12 and the box cover 1 form a whole.

[0072] In a possible implementation, no adhesive member may be provided, but the seal member 12 may serve as the adhesive member. Figure 2 As shown, the seal 12 is made of molding glue, which is applied to the box cover 1, and then cured by curing means, so that the seal 12 is directly bonded to the box cover 1. Since the molding glue has elasticity after curing, this elasticity can maintain the tightness of the seal.

[0073] In addition, since the uncured molding adhesive can be applied to the box cover 1 by machine or manually, and then the molding adhesive is bonded to the box cover 1 by curing, the mold opening cost of the special-shaped sealing member 12 is omitted.

[0074] In order to make the seal between the box cover 1 and the motor housing 3 tighter, in a possible implementation manner, as Figure 7 As shown, Figure 7 The schematic diagram of a part of the structure of a motor 100 provided in an embodiment of the present application. The motor 100 also includes a fastener 2, which passes through the box cover 1 and is threadedly connected to the motor housing 3. By screwing in the fastener 2, the box cover 1 can be pressed in a direction close to the motor housing 3, so that the seal is tighter by pressing.

[0075] In a possible implementation, Figure 7 As shown, the number of fasteners 2 is multiple, and the multiple fasteners 2 are arranged along the junction box opening 31 ( Figure 1 ) are arranged at circumferential intervals, around the terminal box opening 31 ( Figure 1 ) is arranged around one circle. In this way, the box cover 1 can be subjected to uniform pressing force without warping.

[0076] In addition, the fastener 2 can be in various forms in order to compress the box cover 1, and other forms will not be described in detail here.

[0077] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
