BRIEF DESCRIPTION OF DRAWINGS

[0015] The disclosure of the present application will be described with reference to the accompanying drawings. It should be understood that the drawings are only intended for illustrative purposes, and are not intended to limit the scope of protection of the present application. Among them:

[0016] Figure 1 The compressor assembly according to one embodiment of the present application is schematically shown. DETAILED DESCRIPTION

[0017] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive, exemplary, and should not be interpreted as limiting the scope of protection of the present application.

[0018] It should be noted that the orientation terms mentioned herein are defined with respect to the direction in the respective drawings. These orientations are relative concepts and will therefore vary according to the position and state in which they are located. Therefore, these or other orientation terms should not be understood as limiting.

[0019] Figure 1 The compressor assembly 200 according to one embodiment of the present application is schematically shown, wherein a fixing flange 1 is provided at the vehicle-mounted compressor 100 of the compressor assembly 200, the fixing flange 1 is used to fix the vehicle-mounted compressor 100, and the fixing flange 1 extends in a substantially vertical direction. The "vertical direction" coincides with the Z-axis in the automobile coordinate system. The vehicle-mounted compressor 100 is, for example, an electric scroll compressor.

[0020] The fixing flange 1 is, for example, provided at the outer periphery of the housing of the vehicle-mounted compressor 100, and serves to connect the vehicle-mounted compressor 100 and the automobile. The automobile is, for example, an electric commercial vehicle.

[0021] In the compressor assembly 200, a mounting bracket 4 is connected below the vehicle-mounted compressor 100, the vehicle-mounted compressor 100 is connected with the automobile through the mounting bracket 4, and the fixing flange 1 is connected with the mounting bracket 4 through a threaded connection part. The threaded connection part is composed of, for example, a bolt and a nut. For example, a fixing hole is provided in the mounting bracket 4, and the bolt passes through the fixing hole to fix the fixing flange 1 to the mounting bracket 4. A mounting hole can be provided at the mounting bracket 4 for connection to the vehicle frame.

[0022] Through the mounting bracket 4 provided, the vehicle-mounted compressor 100 can be conveniently connected with the vehicle frame, and the mounting bracket 4 can be made of a material with high rigidity. The mounting bracket 4 can be part of the vehicle frame or an independent component relative to the vehicle frame. Here, the vehicle frame should not be interpreted restrictively, and it can also include the vehicle body, the subframe, or other parts fixedly connected with the automobile.

[0023] In the technical solution according to the present application, by extending the fixing flange 1 in the vertical direction, compared with the technical solution of extending the fixing flange 1 in other directions, the vehicle-mounted compressor 100 can be directly fixed below the mounting bracket 4 through the fixing flange 1, thereby simplifying the structure of the mounting bracket 4 and thus facilitating the fixation of the vehicle-mounted compressor 100. Additionally, through such a solution, the intermediate bracket that plays a connecting role between the vehicle-mounted compressor and the mounting bracket is omitted, thereby reducing the number of parts, lowering the system complexity, and shortening the installation time. Furthermore, the connection area between the vehicle-mounted compressor and the mounting bracket is increased through the fixing flange, which can reduce the risk of vibration noise and cracks.

[0024] On the contrary, in the case where the fixing flange extends, for example, in the horizontal direction, the vehicle-mounted compressor cannot be directly fixed below the mounting bracket, and the mounting bracket needs to have a vertically extending section to be connected with the fixing flange, resulting in a complex structure of the mounting bracket and inconvenience in fixing the vehicle-mounted compressor.

[0025] For example, at least two fixing flanges 1 are provided around the center of gravity of the vehicle-mounted compressor 100, for example, a total of 2, 3, 4, 5, or 6 fixing flanges are provided, and the fixing flanges are parallel to each other, thereby providing reliable support for the vehicle-mounted compressor 100. In the case where multiple fixing flanges are provided, in a plane perpendicular to the extension direction of the fixing flanges and passing through the center of gravity of the vehicle-mounted compressor, the center of gravity of the vehicle-mounted compressor is located in the area surrounded by the multiple fixing flanges.

[0026] A feasible solution is to provide two fixing flanges 1 on both sides of the vehicle-mounted compressor 100, for example on both sides relative to the axis of the motor housing of the vehicle-mounted compressor 100. The fixing flanges 1 can also be arranged in other ways, for example one fixing flange 1 on one side of the vehicle-mounted compressor 100 and two fixing flanges 1 on the other side of the vehicle-mounted compressor 100, or a plurality of fixing flanges 1 on each side of the vehicle-mounted compressor 100, or more than three fixing flanges 1 in total provided at each side of the vehicle-mounted compressor 100.

[0027] The fixing flanges 1 can be at least partially integrally formed with the vehicle-mounted compressor 100. Exemplarily, the fixing flanges 1 are integrally formed with the housing of the vehicle-mounted compressor 100, for example integrally cast.

[0028] Further, the vehicle-mounted compressor 100 can comprise a motor housing 2 and an end cover 3. The motor housing 2 is used to accommodate a motor, and the end cover 3 is used to close the end side of the vehicle-mounted compressor 100. A compression module can also be provided between the motor and the end cover 3, which for example comprises a static scroll on which a static scroll ring is provided, and a dynamic scroll on which a dynamic scroll ring is provided, the static scroll ring and the dynamic scroll ring cooperating to form a compression chamber. It can be provided that different fixing flanges 1 are integrally cast with the motor housing 2 and the end cover 3, for example two fixing flanges are integrally cast with the motor housing 2 and two fixing flanges are integrally cast with the end cover 3. "Different fixing flanges" here means that they are not the same fixing flange, rather than being used to define that their shapes and / or structures are different. For example, two fixing flanges 1 are symmetrically arranged about the axis in the circumferential direction of the motor housing 2, and two fixing flanges 1 are symmetrically arranged about the axis in the circumferential direction of the end cover 3, as shown in Figure 1

[0029] The fixing flanges 1 can be made of an aluminum alloy, for example a high-pressure die-cast aluminum alloy. High-pressure die casting can form high-quality parts. After high-pressure die casting, specific areas can be machined to further improve dimensional accuracy and provide better assembly performance. In addition, high-pressure die casting ensures high elongation of the parts, meeting the needs of connections.

[0030] A shock-absorbing pad 5 can be provided between the fixing flanges 1 and the mounting bracket 4. The shock-absorbing pad 5 can be made of rubber or other materials with good shock-absorbing properties. Figure 1 ​In the shown embodiment, a damping pad 5 is provided between one side, in particular the upper side, of the mounting bracket 4 and the fixing flange 1, and another damping pad 5 is provided between the other side, in particular the lower side, of the mounting bracket 4 and the threaded connection, for example the nut 6. It is also possible that a damping pad is provided between the fixing flange 1 and the mounting bracket 4, which damping pad passes through a fixing hole in the mounting bracket 4, one part of the damping pad being between the one side, in particular the upper side, of the mounting bracket 4 and the fixing flange 1 and the other part of the damping pad being between the other side, in particular the lower side, of the mounting bracket 4 and the threaded connection.

[0031] The damping pad 5 can effectively absorb the vibration of the vehicle-mounted compressor 100, reduce the vibration transmitted to the vehicle frame, and thus improve the ride comfort, the NVH performance and the running durability of the vehicle. The damping pad 5 is made of, for example, rubber material, which has good vibration absorption and energy absorption. The stiffness of the damping pad 5 is matched with the vibration energy of the vehicle-mounted compressor 100. In general, the softness and hardness of the material of the damping pad 5 need to be selected considering the vibration absorption capacity and the durability.

[0032] In addition, a weight-reducing groove 11 can be provided in the fixing flange 1 for reducing the weight of the fixing flange 1.

[0033] The present application also includes a vehicle with the vehicle-mounted compressor of any one or more of the preceding embodiments or with the compressor assembly of any one or more of the preceding embodiments, which thus has the technical features and the technical effects corresponding to the foregoing description, and therefore the details are not repeated here.
