[0042] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0043] It should be noted that the terms "initial", "second", etc. in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0044] The intelligent level of vehicles is improved, and the number of various electronic devices in vehicles is increased. For example, electric vehicle doors and other electrical devices related to safety are all electronic devices. Therefore, the stability and reliability of power supply of vehicles are also correspondingly improved.

[0045] The application provides a vehicle, which comprises a motor integrated device.

[0046] As shown in Figure 1 , Figure 1 a partial structure diagram of a power supply mounting structure 100 is provided for an embodiment of the application;

[0047] The application provides a motor integrated device, which comprises a motor, a motor controller and a power supply mounting structure 100, wherein the motor controller is connected with the motor, and the power supply mounting structure 100 is connected with the motor controller.

[0048] The application also provides a power supply mounting structure 100, which comprises a shell 1, a first sealing member 2 and a second sealing member 3. The shell 1 comprises a first side surface 11, and the shell 1 is provided with a containing cavity 12 and a cooling channel 13, the opening of the containing cavity 12 and the opening of the cooling channel 13 are both located on the first side surface 11, the first sealing member 2 is arranged along the circumferential side of the opening of the containing cavity 12 and is connected with the first side surface 11, the second sealing member 3 is arranged along the circumferential side of the opening of the cooling channel 13 and is connected with the first side surface 11, and the second sealing member 3 is arranged in a spaced manner with the first sealing member 2.

[0049] The containing cavity 12 is used for accommodating the devices required by the power supply. The first sealing member 2 seals the containing cavity 12 when the shell 1 is installed, which can reduce the impurities entering the containing cavity 12, reduce the damage of the impurities to the devices in the containing cavity 12, improve the stability of the devices in the containing cavity 12, thereby reducing the frequency of maintenance and repair and saving the cost.

[0050] The cooling channel 13 is filled with cooling liquid, which is used for cooling and heat dissipation of the containing cavity 12. The second sealing member 3 seals the cooling channel 13 when the shell 1 is installed. The second sealing member 3 can seal the cooling channel 13, reduce the risk of leakage of the cooling liquid in the cooling channel 13, and reduce the performance decline or environmental pollution caused by the leakage of the cooling liquid.

[0051] Because there is a temperature difference between the cooling liquid in the cooling channel 13 in the working state and the non-working state, repeated temperature changes will cause fatigue of the sealing member material, and in serious cases, the second sealing member 3 will be damaged.

[0052] When the second sealing member 3 is damaged due to aging, the cooling channel 13 leaks, and the cooling liquid flows out of the cooling channel 13, but is blocked by the first sealing member 2 and cannot flow into the containing cavity 12, so that the first sealing member 2 protects the devices in the containing cavity 12. In this way, the sealing performance of the power supply mounting structure 100 can be improved, and the first sealing member 2 and the second sealing member 3 are provided for protecting the devices in the containing cavity 12, a redundant protection structure is provided, the protection reliability is improved, and the safety of the power supply system of the vehicle is improved.

[0053] It should be noted that the accommodation cavity 12 and the cooling channel 13 are arranged side by side or spaced apart.

[0054] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, and before the embodiments of the present application are described in detail, the application scenarios of the embodiments of the present application are first introduced.

[0055] The power installation structure 100 provided by the present application is used for a motor integrated device, and the motor integrated device at least includes a motor, a motor controller and the power installation structure 100, wherein the motor controller is connected with the motor, and the power installation structure 100 is connected with the motor controller.

[0056] The motor integrated device provided by the present application is used for a vehicle. The vehicle can be one of a sedan, a truck, a commercial vehicle or a special vehicle. The vehicle provided by the present application is an electric vehicle or a hybrid vehicle of electricity and other energy.

[0057] In a possible implementation, the motor controller includes a shell and a cooling loop, and the shell of the motor controller covers the opening and is connected with the housing 1, which can save materials and reduce waste.

[0058] For example, the housing 1 is connected with the shell of the motor controller through bolts, and at the same time, the housing 1 and the shell of the motor controller provide the required pressure for sealing of the first sealing member 2 and the second sealing member 3, which can reduce additional compression structures, simplify the complexity of the device and facilitate production.

[0059] The cooling loop is in communication with the cooling channel 13, and thus arranged, the same cooling source can be used to realize recycling of the cooling liquid, simplify the pipeline layout and installation, and reduce the production and maintenance costs. The communication of the cooling loop and the cooling channel 13 can help to realize more uniform temperature distribution in the whole system, avoiding local overheating or overcooling phenomenon.

[0060] In a possible implementation, the cooling channel 13 can be connected with a cooling source alone, and thus arranged, when the cooling system where the cooling channel 13 is located and the cooling system where the cooling loop is located are separated, fault isolation is realized, and the reliability of the whole system is improved.

[0061] In a possible implementation, the power installation structure 100 includes a cover plate, and the cover plate is used to cover the opening and connect with the housing 1. The cover plate is arranged to facilitate the maintenance of the arrangement in the accommodation cavity 12.

[0062] Referring to Figure 1 and Figure 2 , it is shown that Figure 2 the A-A cross-sectional view in Figure 1 one embodiment provided by the present application.

[0063] In one possible implementation, the housing 1 includes a fixing groove 14 located on the first side 11 and surrounding the opening of the receiving cavity 12. A first seal 2 is located in the fixing groove 14, with at least a portion of the first seal 2 located on the side of the first side 11 opposite to the fixing groove 14. The fixing groove 14 provides an installation position for the first seal 2, facilitating its installation. Simultaneously, the fixing groove 14 limits the movement of the first seal 2 under external forces, reducing its displacement and improving the sealing effect.

[0064] For example, the cross-sectional shape of the fixing groove 14 can be semi-circular, arc-shaped, triangular or rectangular, and the first sealing member 2 located in the fixing groove 14 partially matches the shape of the fixing groove 14, so that the first sealing member 2 can be installed stably when it is located in the fixing groove 14.

[0065] In one possible implementation, the fixing groove 14 penetrates the inner wall surface 121 of the receiving cavity 12. This allows the first sealing member 2 to move towards the receiving cavity 12 under the action of external force when sealing the receiving cavity 12, thereby improving the sealing effect.

[0066] The first seal 2 of the housing 1 located on the side of the fixed groove 14 away from the receiving cavity 12 has a limiting function, which restricts the first seal 2 from moving in the direction away from the receiving cavity 12, thereby reducing the possibility of the seal coming off.

[0067] It should be noted that the first seal 2 is arranged around the opening of the accommodating cavity 12, and the first seal 2 is located in the middle position of the first side 11, which can improve the sealing effect of the first seal 2 and reduce the situation where the first seal 2 is displaced by compression.

[0068] In one possible implementation, the first seal 2 is an elastic soft material. Under the pressure of the housing 1 and the component covering the opening, the first seal 2 can undergo elastic deformation, improving the fit between the first seal 2 and the first side 11, thereby improving the sealing effect.

[0069] In one possible implementation, the first seal 2 on the side of the first side 11 facing away from the fixing groove 14 is a flexible soft material. This ensures that the first seal 2 can simultaneously maintain installation stability and improve the fit between the first seal 2 and the first side 11.

[0070] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 Provided for one embodiment of this application Figure 1 Schematic diagram of the cross section in the middle BB direction.

[0071] In a possible implementation, the shell 1 comprises a mounting groove 15 located on the first side surface 11 and surrounding the opening of the cooling channel 13, the second sealing member 3 is located in the mounting groove 15, and at least a part of the second sealing member 3 is located on the side of the first side surface 11 away from the mounting groove 15. The mounting groove 15 provides a mounting position for the second sealing member 3, facilitates positioning of the second sealing member 3 during installation, limits the second sealing member 3, reduces movement of the second sealing member 3 caused by external force, and improves the sealing effect.

[0072] For example, the cross-sectional shape of the mounting groove 15 can be semicircular, arc-shaped, triangular, or rectangular, and the part of the second sealing member 3 located in the mounting groove 15 matches the shape of the mounting groove 15, so that the second sealing member 3 can be stably mounted in the mounting groove 15.

[0073] In a possible implementation, the second sealing member 3 is connected to the mounting groove 15 in interference fit. In this way, the stability of the installation of the second sealing member 3 can be improved.

[0074] For example, the size of the second sealing member 3 is slightly larger than the size of the mounting groove 15, and external force needs to be applied to connect the second sealing member 3 to the mounting groove 15 in interference fit. In this way, the second sealing member 3 can be fixed more stably.

[0075] For example, the second sealing member 3 is provided with a protruding part on the wall surface of the side wall of the mounting groove 15, the second sealing member 3 matches the mounting groove 15, and the protruding part needs to be connected to the mounting groove 15 in interference fit under the action of external force. In this way, the second sealing member 3 can be fixed more stably.

[0076] In a possible implementation, the second sealing member 3 is a flexible soft member. The second sealing member 3 can be elastically deformed under pressure, improve the adhesion of the second sealing member 3 and the first side surface 11, and further improve the sealing effect.

[0077] In a possible implementation, the second sealing member 3 on the side of the first side surface 11 away from the mounting groove 15 is a flexible soft member. In this way, the second sealing member 3 can simultaneously consider installation stability and improve the adhesion of the second sealing member 3 and the first side surface 11.

[0078] It should be noted that the power supply mounting structure 100 comprises a vehicle charger, a direct current converter, and an inverter, and the vehicle charger, the direct current converter, and the inverter are installed in the accommodating cavity 12. The vehicle charger, the direct current converter, and the inverter provide a basis for stable operation of low-voltage power supply.

[0079] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
