Description

Technical Field

[0001] This application belongs to the field of air-conditioning compressors, and particularly relates to an air-conditioning compressor bracket assembly. Background Art

[0002] In order to meet the comfort needs of passengers and the battery thermal management needs, most existing new energy vehicles are equipped with heating and cooling air conditioners, which makes the electric air-conditioning compressor a key component of the whole vehicle.

[0003] Since the engine of a fuel vehicle has relatively large vibration and noise, the vibration and noise problems of the air-conditioning compressor during driving are not obvious. However, there is no other noise source in an electric vehicle to cover up the vibration and noise of the air-conditioning compressor. Moreover, in the existing technology, the installation points of electric compressors generally adopt the side-mounted form, which is suitable for fixing the air-conditioning compressor unilaterally. However, for some vehicle models, due to installation space limitations, good side-mounted conditions cannot be provided. During the operation of the air-conditioning compressor, due to its high rotational speed, the vibration of the air-conditioning compressor itself will be transmitted to the cab through the frame and the body, affecting the driving experience. Utility Model Content

[0004] This application provides an air-conditioning compressor bracket assembly, which can effectively reduce the noise transmitted from the air-conditioning compressor to the frame and then to the cab, and improve the user's driving experience.

[0005] The technical solution adopted in this application is as follows:

[0006] An air-conditioning compressor bracket assembly includes a bracket main body. The bracket main body includes a first positioning part connected to the air-conditioning compressor and a second positioning part connected to the bottom end of the first positioning part. The air-conditioning compressor is fixed to the top end of the first positioning part. A damping component connected to the frame is provided below the bracket main body. The bottom end of the second positioning part is fixedly connected to the damping component. The damping component includes a damping pad and a magnetic levitation damping structure, and the magnetic levitation damping structure is located inside the damping pad.

[0007] The air-conditioning compressor is connected to the first positioning part of the bracket, and the second positioning part is indirectly connected to the frame through the damping pad. The bracket is located at the top end of the first positioning part, and the first positioning part, the second positioning part, and the damping component are connected in sequence vertically. Thus, the air-conditioning compressor is fixed in a sitting position, avoiding the limitation of installation space in the side-mounted fixing method. At the same time, the damping component is located between the air-conditioning compressor, the air-conditioning compressor bracket, and the frame, weakening the vibration transmitted from the air-conditioning compressor to the frame, and thus reducing the noise transmitted from the air-conditioning compressor to the cab.

[0008] The first positioning part includes an ear, and the second positioning part includes a connecting block. The top end of the ear is fixedly connected to the air-conditioning compressor, and the bottom end of the ear is connected to the connecting block.

[0009] When connecting and fixing the air-conditioning compressor to the vertical ear, since the fixing position of the air-conditioning compressor and the vertical ear is at the top of the vertical ear, and the fixing position of the vertical ear and the connecting block is within the bottom area of the vertical ear, the height of the vertical ear itself is beneficial to extending the vibration transmission path, further weakening the vibration transmitted to the vehicle frame, and thus further reducing the noise.

[0010] A plurality of the vertical ears and the connecting blocks are provided, and the vertical ears and the connecting blocks are arranged in one-to-one correspondence.

[0011] Increase the installation points of the bracket between the compressor and the installation points between the vertical ear and the connecting block, and ensure the structural strength and support strength at each vertical ear, that is, at each connection position with the air-conditioning compressor.

[0012] The first positioning portion further includes a first reinforcing beam located between adjacent vertical ears.

[0013] And / or, the second positioning portion further includes a second reinforcing beam located between adjacent damping pads.

[0014] Four vertical ears and four connecting blocks are provided respectively, and the vertical ears and the connecting blocks are distributed in a rectangular shape.

[0015] Assembly holes are provided in a counterpoint manner at the bottom of the connecting block and the top of the damping pad, and the two assembly holes are connected by fasteners so that the bottom wall of the connecting block abuts against the top wall of the damping pad.

[0016] Bolts can be selected as fasteners for connection, which have low cost, simple forming of the assembly holes, and low connection difficulty. The bottom wall of the connecting block abuts against the top wall of the damping pad, improving the structural compactness between the damping pad and the bracket, and thus realizing the damping effect of the damping pad.

[0017] A cavity is provided inside the damping pad, and the magnetic levitation damping structure includes two mutually repulsive permanent magnets located in the cavity.

[0018] The damping assembly includes the damping solution located in the cavity.

[0019] Two mutually repulsive permanent magnets are arranged inside the damping pad, and the vibration of the air-conditioning compressor is further absorbed through the magnetic levitation structure. Moreover, the cavity filled with the damping solution is beneficial to further weakening the vibration, thus realizing noise reduction.

[0020] Positioning holes are provided at the bottom of the damping pad, and fasteners connecting to the vehicle frame are installed in the positioning holes. Bolts can also be used as fasteners for connection, so that the same mold can be used for processing the assembly holes and the positioning holes, reducing the processing difficulty and the processing cost.

[0021] The assembly holes and the positioning holes are coaxially arranged.

[0022] The assembly hole and the positioning hole are respectively located at the top and bottom of the shock absorber pad, and the coaxial arrangement of the two is beneficial to maintaining the overall stability of the shock absorber pad during connection.

[0023] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

[0024] The first positioning part of the bracket is connected to the air-conditioning compressor, and the second positioning part is indirectly connected to the vehicle frame through the shock absorber pad. The bracket is located at the top of the first positioning part, and the first positioning part, the second positioning part and the shock absorption assembly are connected in sequence vertically. Then the air-conditioning compressor is fixedly installed in a sitting manner, avoiding the limitation of the installation space in the side-mounted fixing method. At the same time, the shock absorption assembly is located between the air-conditioning compressor and the vehicle frame of the air-conditioning compressor bracket, weakening the vibration transmitted from the air-conditioning compressor to the vehicle frame, thereby weakening the noise transmitted from the air-conditioning compressor to the cab.

[0036] The solution of the present application provides an air-conditioning compressor bracket assembly, as Figures 1 to 3 shown, including a bracket main body 2. The bracket main body 2 includes a first positioning portion 21 connected to the air-conditioning compressor 1 and a second positioning portion 22 connected to the bottom end of the first positioning portion 21. The air-conditioning compressor 1 is fixed to the top end of the first positioning portion 21. A vibration damping assembly 3 connected to the vehicle frame is provided below the bracket main body 2. The bottom end of the second positioning portion 22 is fixedly connected to the vibration damping assembly 3. The vibration damping assembly 3 includes a vibration damping pad 31 and a magnetic levitation vibration damping structure, and the magnetic levitation vibration damping structure is located inside the vibration damping pad 31.

[0037] It is connected to the air-conditioning compressor 1 through the first positioning portion 21 of the bracket 2, and the second positioning portion 22 is indirectly connected to the vehicle frame through the vibration damping pad 31. The bracket 2 is located at the top of the first positioning portion 21, and the first positioning portion 21, the second positioning portion 22 and the vibration damping assembly 3 are connected in sequence vertically. Then, the air-conditioning compressor 1 is fixedly installed in a sitting manner, avoiding the limitation of the installation space in the side-mounted fixing method. At the same time, the vibration damping assembly 3 is located between the air-conditioning compressor 1, the bracket 2 of the air-conditioning compressor 1 and the vehicle frame, weakening the vibration transmitted from the air-conditioning compressor 1 to the vehicle frame, thereby weakening the noise transmitted from the air-conditioning compressor 1 into the cab.

[0038] In one embodiment, as Figure 2 shown, the first positioning portion 21 includes an ear 211, and the second positioning portion 22 includes a connecting block 221. The top end of the ear 211 is fixedly connected to the air-conditioning compressor 1, and the bottom end of the ear 211 is connected to the connecting block 221.

[0039] When the air-conditioning compressor 1 is connected and fixed to the ear 211, since the fixing position of the air-conditioning compressor 1 and the ear 211 is at the top end of the ear 211, and the fixing position of the ear 211 and the connecting block 221 is within the bottom end area of the ear 211, the height of the ear 211 itself is conducive to extending the vibration transmission path, further weakening the vibration transmitted to the vehicle frame, and thus further weakening the noise. An installation hole 213 adapted to the air-conditioning compressor 1 is provided at the top end of the ear 211. The bottom end of the ear 211 can be welded to the connecting block 221 or integrally formed with the connecting block 221 to ensure the stability between the two.

[0045] Preferably, the bottom end of the upright ear 211 is bent so that the upright ear 211 is connected to both the top wall and the side wall of the connecting block 221 simultaneously, strengthening the stability of the upright ear 211. At the same time, a first reinforcing beam 212 and a second reinforcing beam 222 are provided. For example, two opposite first reinforcing beams 212 and two opposite second reinforcing beams 222 are provided, and the projections of the first reinforcing beam 212 and the second reinforcing beam 222 in the horizontal plane are perpendicular to each other to enhance the overall connection strength of the bracket 2, thereby enhancing the support connection effect of the bracket 2 on the air-conditioning compressor 1. Moreover, by setting the first reinforcing beam 212 and the second reinforcing beam 222 in this way, it is not necessary to set the first reinforcing beam 212 or the second reinforcing beam 222 at each adjacent upright ear 211 and connecting block 221, which is beneficial to reducing the overall weight of the bracket 2.

[0046] In one embodiment, as Figure 2 、 Figure 3 shown, assembly holes 34 are provided in a position corresponding to the top of the damping pad 31 at the bottom of the connecting block 221, and the two assembly holes 34 are connected by fasteners so that the bottom wall of the connecting block 221 abuts against the top wall of the damping pad 31.

[0047] Bolts 4 can be selected as the fasteners for connection, which have low cost, simple forming of the assembly holes 34, and low connection difficulty. The bottom wall of the connecting block 221 abuts against the top wall of the damping pad 31, enhancing the structural compactness between the damping pad 31 and the bracket 2, thereby realizing the damping effect of the damping pad 31.

[0048] It should be noted that the specific shapes of the connecting block 221 and the damping pad 31 are not limited. Preferably, the connecting surface of the damping pad 31 and the connecting block 221 is set to be circular.

[0049] Furthermore, positioning holes 35 are provided at the bottom of the damping pad 31, and fasteners connected to the vehicle frame are installed in the positioning holes 35. Bolts 4 can also be used as the fasteners for connection, so that the same mold can be used for machining the assembly holes 34 and the positioning holes 35, reducing the machining difficulty and the machining cost.

[0050] Preferably, the assembly holes 34 and the positioning holes 35 are coaxially arranged.

[0051] The assembly holes 34 and the positioning holes 35 are respectively located at the top and the bottom of the damping pad 31, and their coaxial arrangement is beneficial to maintaining the overall stability of the damping pad 31 during connection.

[0052] Preferably, an avoidance cavity is provided inside the damping pad 31, and the magnetic levitation damping structure includes two mutually repulsive permanent magnets 32 located in the avoidance cavity.

[0053] Preferably, the damping assembly 3 includes a damping solution 33 located in the avoidance cavity.

Moreover, the inside of the cavity is filled with a vibration damping solution 33. Preferably, the vibration damping solution 33 is a mixture of ethylene glycol and water, which also absorbs the vibration of the air-conditioning compressor 1 to further reduce the vibration transmitted to the vehicle frame.

[0055] Preferably, the bracket 2 is made of a lightweight material PA66 and glass fiber to reduce the overall weight of the bracket 2.
