Description

Technical Field

[0001] This application relates to the field of vehicle air conditioning technology, and more particularly to a bracket. Background Technology

[0002] The vehicle's air conditioning compressor drives the cooling system's cooling pipes to circulate, achieving cooling or heating through a reverse Carnot cycle. During operation, the compressor generates vibrations, which are transmitted to the vehicle frame, producing noise that can affect passenger comfort. Related technologies use vibration-damping brackets between the compressor and the subframe for vibration reduction; however, these brackets are often heavy or ineffective, impacting the vehicle's driving range. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a bracket that achieves good vibration reduction while being lightweight.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] This application discloses a bracket for a vehicle air conditioning compressor, comprising:

[0006] A flat support plate is used to support the vehicle air conditioning compressor, and the support plate has mounting holes;

[0007] A bushing assembly includes an inner tube and a buffer member. The buffer member includes a first sleeve portion, a second sleeve portion, and a transition portion. The first sleeve portion is disposed around the outside of the second sleeve portion. The transition portion connects the first sleeve portion and the second sleeve portion. The first sleeve portion is disposed in the mounting hole. The second sleeve portion is sleeved on the outside of the inner tube. A portion of the inner tube extends out of the mounting hole for connection with the subframe of the vehicle.

[0008] In one embodiment, there are multiple transition portions, which are spaced apart circumferentially along the mounting hole.

[0009] In one embodiment, the buffer includes an abutment portion disposed within the first sleeve portion, and the abutment portion and the second sleeve portion have a gap between them along the radial direction of the mounting hole.

[0010] In one embodiment, there are multiple abutting portions and multiple transition portions, with the multiple transition portions spaced circumferentially along the mounting hole, and at least one abutting portion between two adjacent transition portions; and / or,

[0011] The outer circumferential surface of the inner tube is connected to the interior of the second sleeve portion. A portion of the second sleeve portion protrudes outward to form a protrusion, and the protrusion and the abutment portion are arranged radially spaced along the mounting hole.

[0012] In one embodiment, the bushing assembly includes an outer tube that is sleeved on the outside of the first sleeve portion and located within the mounting hole, the outer tube being interference-fitted with the mounting hole.

[0013] In one embodiment, a limiting rib is formed on the outer peripheral surface of the outer tube, and the limiting rib abuts against the wall of the mounting hole when the outer tube is located in the mounting hole.

[0014] In one embodiment, the bushing assembly includes a limiting member disposed at the other end of the inner tube relative to the subframe, the limiting member having a dimension in the radial direction of the mounting hole larger than the diameter of the mounting hole.

[0015] In one embodiment, the limiting member and one of the inner tubes form a buckle, and the limiting member and one of the inner tubes form a groove, with the buckle engaging with the groove.

[0016] In one embodiment, the support plate has a first side and a second side opposite to each other along a first direction, and at least one bushing assembly is provided on both the first side and the second side, wherein the first direction is perpendicular to the thickness direction of the support plate.

[0017] In one embodiment, the support plate has opposing third and fourth sides along a second direction, and at least one of the bushing assemblies is disposed on the third side and / or the fourth side, wherein the second direction is perpendicular to the thickness direction of the support plate and intersects the first direction.

[0018] In one embodiment, the bracket includes at least one support member, and at least one bushing assembly is provided as a connecting side on the first side, the second side, the third side, and the fourth side. The support member is connected to at least one bushing assembly on the connecting side and is connected to the subframe.

[0019] In one embodiment, the transition portion has a first end and a second end opposite to each other along the thickness direction of the support plate. The first end is connected to the side of the first sleeve portion near the vehicle air conditioning compressor along the thickness direction of the support plate, and the second end is bent and connected to the side of the second sleeve portion away from the vehicle air conditioning compressor along the thickness direction of the support plate; or,

[0020] The transition portion connects the first sleeve portion and the second sleeve portion at the middle along the thickness direction of the bearing plate; or,

[0021] The transition portion is connected to one end of the first sleeve portion and the second sleeve portion along the thickness direction of the bearing plate.

[0022] In one embodiment, the support plate has a support surface, which is a plane, and the vehicle air conditioning compressor is disposed on the support surface; or,

[0023] The support plate has a support surface, and the support surface is recessed along the thickness direction of the support plate to form a receiving groove. The shape of the receiving groove is adapted to the shape of the bottom of the vehicle air conditioning compressor. When the vehicle air conditioning compressor is located in the receiving groove, the dimension between the bottom of the vehicle air conditioning compressor and the peripheral wall of the receiving groove is less than a preset threshold.

[0024] This application discloses a bracket that uses a flat support plate to support a vehicle air conditioning compressor. Compared to the U-shaped or L-shaped support structure in the cradle-type brackets of the prior art, it eliminates the need for side wall supports on the side of the vehicle air conditioning compressor. In other words, the support plate provided in this application can achieve lightweighting by eliminating the side wall supports in the related art, thereby reducing the weight of the vehicle and increasing the vehicle's driving range.

[0025] By incorporating an inner tube and a buffer, the portion of the inner tube extending through the mounting hole can connect to the vehicle's subframe. A second sleeve is fitted onto the outside of the inner tube, while a first sleeve is positioned inside the mounting hole and surrounds the outside of the second sleeve. A transition section connects the first and second sleeves. In this way, the load-bearing force transmitted from the vehicle's air conditioning compressor to the load-bearing plate can be transferred to the inner tube through the first sleeve, the transition section, and the second sleeve, and then to the subframe through the inner tube. During vibration transmission, the relative movement between the mounting hole wall and the inner tube can be converted into the internal energy of the buffer by the deformation of the first sleeve (contacting the mounting hole wall), the second sleeve (contacting the inner tube), and the transition section between the first and second sleeves. This absorption and dispersion of vibration reduces the noise generated by the vehicle's air conditioning compressor, providing users with a quieter and more comfortable riding environment and a better user experience.

[0043] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0044] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] This application provides a bracket; please refer to [the relevant documentation]. Figures 1 to 15 The bracket 100 includes a flat support plate 1 and a bushing assembly 2. The support plate 1 supports the vehicle's air conditioning compressor and has mounting holes. The bushing assembly 2 includes an inner tube 21 and a buffer member 22. The buffer member 22 includes a first sleeve portion 221, a second sleeve portion 222, and a transition portion 223. The first sleeve portion 221 is disposed around the outside of the second sleeve portion 222. The transition portion 223 connects the first sleeve portion 221 and the second sleeve portion 222. The first sleeve portion 221 is disposed within the mounting hole, and the second sleeve portion 222 is sleeved on the outside of the inner tube 21. A portion of the inner tube 21 protrudes from the mounting hole for connection with the vehicle's subframe.

[0046] For example, bracket 100 can be applied to any type of vehicle, such as pure electric vehicles, hybrid electric vehicles, range-extended vehicles, and gasoline vehicles. Bracket 100 can also be applied to any type of air conditioning compressor. Depending on the power source of the vehicle's air conditioning compressor, the compressor can be a compressor with a drive unit, which obtains power from the vehicle's battery, power battery, or directly from the engine; the compressor can also be a compressor without a drive unit, which obtains kinetic energy from the vehicle's crankshaft or electric motor.

[0047] The bracket 100 provided in this application, by setting a flat support plate 1, is used to support the vehicle air conditioning compressor. Compared with the U-shaped or L-shaped support structure in the cradle-type bracket in the prior art, it is not necessary to set a side wall bracket on the side of the vehicle air conditioning compressor. In other words, the support plate 1 provided in this application embodiment can achieve the weight reduction of the bracket 100 by eliminating the side wall bracket in the related technology, thereby reducing the weight of the vehicle and increasing the vehicle's driving range.

[0048] By setting the inner tube 21 and the buffer 22, the portion of the inner tube 21 that extends out of the mounting hole can be connected to the vehicle's subframe. The second sleeve 222 is fitted onto the outside of the inner tube 21. The first sleeve 221 is disposed within the mounting hole and surrounds the outside of the second sleeve 222. The transition portion 223 connects the first sleeve 221 and the second sleeve 222. In this way, the load-bearing force transmitted from the vehicle's air conditioning compressor to the load-bearing plate 1 can be transmitted to the inner tube 21 through the first sleeve 221, the transition portion 223, and the second sleeve 222, and then transmitted to the load-bearing plate 1 through the inner tube 21. In the subframe, during the transmission of vibration, the relative movement between the wall of the mounting hole and the inner tube 21 can be converted into the internal energy of the buffer 22 through the deformation of the first socket 221 that contacts the wall of the mounting hole, the second socket 222 that contacts the inner tube 21, and the transition portion 223 located between the first socket 221 and the second socket 222. In this way, the vibration can be absorbed and dispersed to reduce the noise generated when the vehicle's air conditioning compressor vibrates, providing users with a quieter and more comfortable riding environment and a better user experience.

[0049] It should be noted that the vehicle air conditioning compressor has greater vibration intensity in the vertical direction, and the buffer 22 of the bushing assembly 2 has greater stiffness in the axial direction and less stiffness in the direction perpendicular to the axial direction, thereby giving the bushing assembly 2 a longer service life and better vibration isolation performance. In related technologies, the cradle-type bracket is connected to the vehicle air conditioning compressor through the horizontal part of the L-shaped or U-shaped bracket, and the vertical part of the cradle-type bracket is connected to the subframe through the bushing assembly, so that the axis of the bushing assembly is perpendicular to the vertical direction. That is, the direction with less stiffness of the bushing assembly is used to bear the vertical vibration of the vehicle air conditioning compressor, which has greater vibration intensity. The cradle-type bracket requires a side wall bracket located on the side of the vehicle air conditioning compressor. This application replaces the L-shaped or U-shaped bracket with a flat plate bearing plate 1, and By using the bushing assembly 2 with its high axial stiffness to support the weight of the vehicle's air conditioning compressor, the bracket 100 has sufficient axial stiffness. This allows the bracket 100 to eliminate the side wall bracket located on the side of the air conditioning compressor while maintaining good vibration damping performance, thereby reducing the spatial dimensions of the bracket 100 and making it lighter. This achieves a lightweight design for the bracket 100. Furthermore, when the bracket 100 is applied to electric vehicles or hybrid vehicles, the lightweight bracket 100 can also extend the driving range of the electric vehicles or hybrid vehicles.

[0050] For example, in one embodiment, the vertical direction can be the thickness direction of the support plate 1, the first direction can be the length direction of the support plate 1, and the second direction can be the width direction of the support plate 1.

[0051] In one exemplary embodiment, Figure 1 In this context, R1 can be the thickness direction of the bearing plate 1, R2 can be the first direction, and R3 can be the second direction.

[0052] For example, in one embodiment, the vehicle air conditioning compressor can be supported above the support plate 1, so that the weight of the vehicle air conditioning compressor and the vibration generated during operation can be transmitted vertically to the support plate 1, and then transmitted to the subframe through the bushing assembly 2.

[0053] In some embodiments, the support plate 1 can also be indirectly connected to the bracket 100 through other connection structures, so that the vibration of the vehicle air conditioning compressor during operation can also be transmitted to the support plate 1.

[0054] In one embodiment, please refer to Figures 1 to 3 There are multiple mounting holes and bushing assemblies 2. Multiple mounting holes are arranged at intervals around the support plate 1. Each mounting hole is equipped with a bushing assembly 2. The geometric center points of at least three bushing assemblies 2 on the horizontal plane are not collinear, and the central axis of each bushing assembly 2 is parallel to the vertical direction. The horizontal plane is a plane perpendicular to the vertical direction.

[0055] For example, the number of mounting holes and bushing assemblies 2 can be three. The three bushing assemblies 2, whose geometric centers are not collinear, form a support surface parallel to the horizontal plane. This support surface restricts the pitch and rotation of the vehicle's air conditioning compressor along its horizontal axis in all directions. This horizontal axis is a central axis perpendicular to the vertical direction, and the horizontal plane is a plane perpendicular to the vertical plane. Simultaneously, the central axis of each bushing assembly 2 is parallel to the vertical direction, and the axial support of the bushing assembly 2 bears the weight of the vehicle's air conditioning compressor as well as vertical vibrations.

[0056] In one embodiment, the buffer 22 can be made of rubber, which can improve the vibration damping effect.

[0057] In one embodiment, please refer to Figure 7 The transition portion 223 has a first end 223a and a second end 223b opposite to each other along the thickness direction of the support plate 1. The first end 223a is connected to the side of the first sleeve portion 221 near the vehicle air conditioning compressor along the thickness direction of the support plate 1, and the second end 223b is bent and connected to the side of the second sleeve portion 222 away from the vehicle air conditioning compressor along the thickness direction of the support plate 1.

[0058] In this way, the transition part 223 can not only improve the connection strength between the first socket part 221 and the second socket part 222, but also, due to the bending of the second end 223b, there is a larger gap between the first end 223a and the second socket part 222, which can provide a larger movement space between the inner tube 21 and the support plate 1 to disperse the vibration generated by the vehicle air conditioning compressor.

[0059] In one embodiment, please refer to Figure 7 The transition portion 223 is connected to the middle of the first socket portion 221 and the second socket portion 222 along the thickness direction of the bearing plate 1.

[0060] This can improve the connection strength between the first socket 221 and the second socket 222, as well as the overall rigidity of the buffer 22.

[0061] In one embodiment, please refer to Figure 11 The transition portion 223 is connected to one end of the first socket portion 221 and the second socket portion 222 along the thickness direction of the bearing plate 1.

[0062] In this way, the first socket 221 and the second socket 222 form a larger space relative to the other end of the transition portion 223 along the thickness direction of the support plate 1, so as to provide a larger movement space between the inner tube 21 and the support plate 1 to disperse the vibration generated by the vehicle air conditioning compressor.

[0063] In one embodiment, the support plate 1 is made of plastic. Compared with metal materials, the support plate 1 made of plastic further reduces the weight of the vehicle air conditioning bracket 100. When the bracket 100 is applied to electric vehicles or hybrid vehicles, it further increases the driving range of electric vehicles and hybrid vehicles. At the same time, compared with metal materials, plastic can also produce a certain degree of elastic deformation when subjected to vertical external forces. Thus, the elastic deformation of the support plate 1 can further buffer the vertical vibration of the vehicle air conditioning compressor, thereby improving the vibration reduction performance of the bracket 100.

[0064] In one embodiment, please refer to Figure 7 and Figure 9 The number of transition portions 223 is multiple, and the multiple transition portions 223 are arranged at intervals along the circumference of the mounting hole.

[0065] For example, the number of transition portions 223 can be four, and the four transition portions 223 are arranged at 90° intervals along the circumference of the mounting hole.

[0066] Here, by providing multiple transition portions 223 at axial intervals along the mounting hole, that is, by having a gap between adjacent transition portions 223, on the one hand, a larger movement space can be provided between the inner tube 21 and the support plate 1 to disperse the vibration generated by the vehicle air conditioning compressor, avoid vibration stress concentration, and thus extend the service life of the buffer 22 and related components; on the other hand, by providing multiple transition portions 223, the connection strength between the first socket 221 and the second socket 222 can be improved, so that the positioning accuracy of the inner tube 21 can be improved and the working stability during the vibration reduction process can be improved.

[0067] In one embodiment, please refer to Figure 4 , Figure 7 and Figure 9 The buffer 22 includes an abutment portion 224, which is disposed within the first socket portion 221. The abutment portion 224 and the second socket portion 222 have a gap between them along the radial direction of the mounting hole.

[0068] Here, by forming a gap between the abutment portion 224 and the second socket portion 222, when the inner tube 21 is installed into the second socket portion 222, the outward expansion deformation of the second socket portion 222 can be stopped by the abutment portion 224. In this way, by buffering the deformation of the transition portion 223, the fatigue life of the bushing assembly 2 can be improved.

[0069] In one embodiment, please refer to Figure 4 , Figure 7 and Figure 9 There are multiple abutting portions 224 and multiple transition portions 223. Multiple transition portions 223 are arranged at intervals along the circumference of the mounting hole, and at least one abutting portion 224 is provided between two adjacent transition portions 223.

[0070] For example, the number of abutting portions 224 and transition portions 223 can both be four. The four transition portions 223 can be arranged at 90° intervals along the circumference of the mounting hole, and an abutting portion 224 can be provided between each two adjacent transition portions 223.

[0071] In this way, while the transition section 223 improves the connection strength between the first socket section 221 and the second socket section 222 and reduces vibration, the multiple abutment sections 224 can further improve the service life of the entire support vibration reduction system.

[0072] In one embodiment, please refer to Figure 4 , Figure 10 , Figure 12 and Figure 13 The bushing assembly 2 includes an outer tube 23, which is sleeved on the outside of the first sleeve portion 221 and located inside the mounting hole. The outer tube 23 is interference-fitted with the mounting hole.

[0073] In this way, on the one hand, the bearing plate 1 can transfer the bearing force to the outer tube 23 through the interference fit between the hole wall of the mounting hole and the outer wall of the outer tube 23. Then, the outer tube 23 can transfer it to the inner tube 21 through the buffer 22, and finally to the subframe connected to the inner tube 21. On the other hand, the vibration generated by the vehicle air conditioning compressor will cause relative movement between the inner tube 21 and the outer tube 23, so as to squeeze the buffer 22 located between them. The first socket 221, the second socket 222 and the transition part 223 located between them can be deformed to convert the kinetic energy of the vibration into the internal energy of the buffer 22, thereby completing the absorption and dispersion of vibration. Furthermore, the interference fit between the outer tube 23 and the mounting hole can improve the connection strength between the bushing assembly 2 and the bearing plate 1, so that the bushing assembly 2 can stably restrict the vertical movement of the bearing plate 1 and the vehicle air conditioning compressor, and extend the service life of the bracket 100.

[0074] In one embodiment, the bushing assembly 2 includes a limiting member 24 disposed at the other end of the inner tube 21 relative to the subframe, and the dimension of the limiting member 24 in the radial direction of the mounting hole is larger than the diameter of the mounting hole.

[0075] For example, the subframe and the limiting member 24 can be located on both sides of the inner tube 21 along its thickness direction. In this way, the inner tube 21 can be limited along the thickness direction of the support plate 1, and the support plate 1 and the vehicle air conditioning compressor can be limited along the thickness direction of the support plate 1. This can reduce the possibility of damage or noise to the support plate 1 and the vehicle air conditioning compressor due to collisions with other components. At the same time, it can also reduce the entry of debris, dust and other objects into the bushing assembly 2, thereby extending the service life of the bushing assembly 2.

[0076] In one embodiment, please refer to Figure 5 and Figure 6 One of the limiting member 24 and the inner tube 21 forms a buckle 24a, and one of the limiting member 24 and the inner tube 21 forms a groove 21a, and the buckle 24a and the groove 21a engage with each other.

[0077] For example, a buckle 24a can be formed in the middle of the limiting member 24, and a groove 21a can be formed inside the inner tube 21. In this way, by the cooperation of the buckle 24a and the groove 21a, the connection strength between the limiting member 24 and the inner tube 21 can be improved, the detachment of the limiting member 24 during transportation can be reduced, and the stability of the limiting function of the limiting member 24 can be improved.

[0078] In some embodiments, please refer to Figure 15 The limiting member 24 can be connected to the inner tube 21 by other means such as adhesive bonding or interference fit with the periphery of the mounting hole.

[0079] In one embodiment, please refer to Figure 3 The support plate 1 has a support surface 1a, which is a plane, and the vehicle air conditioning compressor is disposed on the support surface 1a. For example, the fastener can be a screw or bolt, etc. In this way, by directly mounting the vehicle air conditioning compressor onto the support plate 1 using fasteners, the installation steps can be reduced and the processing difficulty of the support plate 1 can be decreased, resulting in high assembly efficiency.

[0080] In one embodiment, please refer to Figure 1 and Figure 2 The support plate 1 has a support surface 1a, and the support surface 1a is recessed along the thickness direction of the support plate 1 to form a receiving groove 1b. The shape of the receiving groove 1b is adapted to the shape of the bottom of the vehicle air conditioning compressor. When the vehicle air conditioning compressor is located in the receiving groove 1b, the dimension between the bottom of the vehicle air conditioning compressor and the peripheral wall of the receiving groove 1b is less than a preset threshold. In this way, the setting of the receiving groove 1b not only facilitates the positioning and installation of the vehicle air conditioning compressor.

[0081] In one embodiment, please refer to Figures 1 to 3 The bracket 100 also includes a metal insert ring 3 and fasteners. The metal insert ring 3 is embedded in the support plate 1 and extends through the support plate 1 along the thickness direction of the support plate 1. The metal insert ring 3 has a threaded hole for connecting the vehicle air conditioning compressor. The vehicle air conditioning compressor has a mounting port. The fasteners pass through the mounting port and are threaded into the threaded hole.

[0082] For example, the fasteners can be screws or bolts. This further enhances the connection strength between the vehicle air conditioning compressor and the support plate 1, enabling the vehicle air conditioning compressor to be connected to the support plate 1 more reliably. Optionally, the axes of each threaded hole are parallel to the vertical direction, so that during the installation of the vehicle air conditioning compressor, each bolt can achieve the connection between the vehicle air conditioning compressor and the support plate 1 through longitudinal movement, which facilitates the installation of the vehicle air conditioning and improves the ease of installation.

[0083] In one embodiment, please refer to Figure 7 and Figure 8 The outer peripheral surface of the inner tube 21 is connected to the interior of the second sleeve 222. A portion of the second sleeve 222 protrudes outward to form a protrusion 222a. The protrusion 222a and the abutment portion 224 are arranged radially apart along the mounting hole.

[0084] For example, the inner tube 21 and the second socket 222 can be a vulcanized integral structure, or the inner tube 21 and the second socket 222 can be connected by an interference fit, so that the outer peripheral surface of the inner tube 21 and the interior of the second socket 222 are connected. A portion of the second socket 222 can protrude outward to form a protrusion 222a, and the corresponding portion of the inner tube 21 can also protrude outward to form a ridge 21b. The ridge 21b is located on the inner surface of the protrusion 222a, and the protrusion 222a and the abutment portion 224 are arranged radially apart along the mounting hole.

[0085] In this way, by protruding outward in part of the second socket 222 to form a protrusion 222a, the abutment 224 can be limited to a certain extent, thereby reducing the relative movement gap between the second socket 222 and the abutment 224. This not only satisfies the vibration reduction requirement, but also improves the fatigue performance of the bushing assembly 2, thereby increasing the overall service life of the bracket.

[0086] In one embodiment, please refer to Figures 1 to 3 The support plate 1 has a first side 1c and a second side 1d along a first direction, and each of the first side 1c and the second side 1d is provided with at least one bushing assembly 2, wherein the first direction is perpendicular to the thickness direction of the support plate 1.

[0087] For example, the first side 1c may be provided with two bushing components 2, and the second side 1d may be provided with one bushing component 2; or, the first side 1c may be provided with one bushing component 2, and the second side 1d may also be provided with one bushing component 2; or, the first side 1c may be provided with two bushing components 2, and the second side 1d may also be provided with two bushing components 2.

[0088] This can limit the swaying and rotation of the vehicle air conditioning compressor relative to the bracket 100 to a certain extent, thereby further enhancing the reliability of the bracket 100 in supporting the vehicle air conditioning compressor.

[0089] In one embodiment, please refer to Figures 1 to 3 The support plate 1 has a third side 1e and a fourth side 1f opposite each other along the second direction, and at least one bushing assembly 2 is provided on the third side 1e and / or the fourth side 1f, wherein the second direction is perpendicular to the thickness direction of the support plate 1 and intersects the first direction.

[0090] For example, a bushing assembly 2 may be provided on the third side 1e, and the bushing assembly 2 may not be provided on the fourth side 1f; or, the bushing assembly 2 may not be provided on the third side 1e, and the bushing assembly 2 may be provided on the fourth side 1f; or, the bushing assembly 2 may be provided on the third side 1e, and the bushing assembly 2 may be provided on the fourth side 1f.

[0091] In this way, by providing at least one bushing assembly 2 on the third side 1e and / or the fourth side 1f, the line connecting the geometric centers of the bushing assembly 2 in the horizontal inner area can form a stable shape such as a triangle, thereby limiting the swaying and rotation of the vehicle air conditioning compressor relative to the bracket 100 through a more stable shape, so as to further enhance the support reliability of the bracket 100 for the vehicle air conditioning compressor.

[0092] In one embodiment, please refer to Figure 2 and Figure 3 The bracket 100 includes at least one support member 4. At least one bushing assembly 2 is provided on the first side 1c, the second side 1d, the third side 1e and the fourth side 1f as a connecting side. The support member 4 is connected to at least one bushing assembly 2 on the connecting side and is connected to the subframe.

[0093] For example, the number of support members 4 can be one. The first side 1c can have two bushing assemblies 2, the second side 1d can have one bushing assembly 2, and the third side 1e and the fourth side 1f can be without bushing assemblies 2. One end of the support member 4 along the thickness direction of the support plate 1 is connected to the two bushing assemblies 2 of the first side 1c, and the other end of the support member 4 along the thickness direction of the support plate 1 can be connected to the subframe via fasteners. In other embodiments, the number of support members 4 can be two. The first side 1c and the second side 1d can each have two bushing assemblies 2, and the third side 1e and the fourth side 1f can be without bushing assemblies 2. One of the two support members 4 can be connected to the two bushing assemblies 2 of the first side 1c, and the other of the two support members 4 can be connected to the two bushing assemblies 2 of the second side 1d.

[0094] Here, by setting the support member 4, the gravity and vibration borne by the bushing assembly 2 can be transferred to the subframe. Furthermore, by adjusting the design position of the bushing assembly, the support member 4 can meet the frequency avoidance requirements and improve the vibration isolation performance of the support system.

[0095] For example, in one embodiment, the support member 4 can be made of metal, such as aluminum. By making the support member 4 a metal, the good strength and rigidity of metal can be utilized to withstand the vibration of the air conditioner compressor.

[0096] In one embodiment, please refer to Figure 10 The outer tube 23 has an outwardly protruding flange 23a on one side along the thickness direction of the bearing plate 1. The flange 23a is used to abut and limit the movement against the periphery of the mounting hole. This reduces the possibility of the outer tube 23 falling out of the mounting hole, resulting in good installation stability.

[0097] In one embodiment, please refer to Figure 7The first socket 221 has an outward protrusion 221b on one side along the thickness direction of the bearing plate 1. When the outer tube 23 is sleeved on the outside of the first socket 221, the protrusion 221b can abut and limit the outer tube 23 along the thickness direction of the bearing plate 1, and can abut and limit the peripheral edge of the mounting hole, reducing the possibility of the outer tube 23 falling off the mounting hole, and improving installation stability.

[0098] In one embodiment, please refer to Figure 1 and Figure 3 The bracket 100 includes a conductive element 5, which is embedded in the support plate 1 and connected to at least one metal ring 3, thereby forming an integral conductive structure through the conductive element 5 and the metal ring 3 connected to the conductive element 5. The metal casing of the vehicle air conditioning compressor transfers electrical energy to the conductive structure through contact with the metal ring 3.

[0099] In one embodiment, the grounding conductivity of the metal casing of the vehicle air conditioning compressor can also be achieved by transferring electrical energy through a conductive element 5 installed on the top of the vehicle air conditioning compressor. In other words, the conductive element 5 does not need to be installed on the bracket 100. This reduces the amount of metal material used in the bracket 100 and achieves a lightweight design.

[0100] In one embodiment, please refer to Figure 10 The outer circumferential surface of the outer tube 23 forms a limiting rib 23b, which abuts against the wall of the mounting hole when the outer tube 23 is located inside the mounting hole.

[0101] This improves the connection strength between the outer tube 23 and the wall of the mounting hole, reduces the possibility of the outer tube 23 coming out of the mounting hole, and ensures good operational stability.

[0102] In one embodiment, please refer to Figure 9 , Figure 11 and Figure 14 The inner tube 21 can be press-fitted with the second socket 222 to improve the connection strength between the two.

[0103] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
