[0029] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are well known to those skilled in the art. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0030] As shown in Figures 1 to 7 The present application provides a motor suspension assembly, which is connected between a motor device, a compressor 4 and a sub-frame, and includes a suspension bracket 1 having a compressor mounting portion 11, a sub-frame mounting portion 12 and a motor device mounting portion 13 arranged at intervals, the motor device mounting portion 13 being used to connect the motor device; a compressor vibration isolation member 2 mounted on the compressor mounting portion 11, the compressor 4 being flexibly connected to the suspension bracket 1 through the compressor vibration isolation member 2; and a sub-frame vibration isolation member 3 mounted on the sub-frame mounting portion 12, the suspension bracket 1 being flexibly connected to the sub-frame through the sub-frame vibration isolation member 3.

[0031] In particular embodiments, the motor suspension assembly of the present application includes the suspension bracket 1, the compressor vibration isolation member 2 and the sub-frame vibration isolation member 3, the motor device is mounted on the motor device mounting portion 13 of the suspension bracket 1, the sub-frame is flexibly connected to the sub-frame mounting portion 12 of the suspension bracket 1 through the sub-frame vibration isolation member 3, and the compressor 4 is flexibly connected to the compressor mounting portion 11 of the suspension bracket 1 through the compressor vibration isolation member 2, so that the motor device, the compressor 4 and the sub-frame are integrally arranged, and the installation space in the vehicle is reasonably utilized after the compressor 4 is mounted on the motor suspension assembly.

[0032] The vibration generated by the operation of the compressor 4 is transmitted to the compressor vibration isolation member 2. Since the compressor vibration isolation member 2 and the compressor mounting portion 11 are flexibly connected, the compressor vibration isolation member 2 buffers the vibration, so that only a small part of the vibration is transmitted to the suspension bracket 1. Since the auxiliary frame vibration isolation member 3 and the auxiliary frame mounting portion 12 of the suspension bracket 1 are flexibly connected, the vibration of the suspension bracket 1 is further weakened under the buffering action of the auxiliary frame vibration isolation member 3, thereby achieving a two-stage vibration isolation effect for the compressor 4, avoiding excessive vibration of the auxiliary frame, and ensuring the use experience of the vehicle.

[0033] As shown in Figures 4 to 6 The motor suspension assembly of the embodiment of the application, wherein the compressor vibration isolation member 2 comprises a first inner core 21, a rubber bushing 22 and a first outer tube 23 which are sequentially connected in a cylindrical structure. The first inner core 21 has a first connecting hole 211 which is arranged through the first inner core 21 along the extension direction of the first inner core 21. The compressor 4 is connected to the compressor vibration isolation member 2 through the first connecting hole 211.

[0034] In specific implementation, the rubber bushing 22 is sleeved on the outer circumferential surface of the first inner core 21, and the first outer tube 23 is sleeved on the outer circumferential surface of the rubber bushing 22, so that the first inner core 21 and the first outer tube 23 are arranged at intervals and are flexibly connected through the rubber bushing 22 made of flexible material. When the compressor 4 is connected in the first connecting hole 211 of the first inner core 21, and the compressor mounting portion 11 of the suspension bracket 1 is connected to the first outer tube 23, the vibration generated by the compressor 4 cannot be transmitted to the first outer tube 23 under the buffering action of the rubber bushing 22, so that the suspension bracket 1 connected to the first outer tube 23 is less affected by the vibration, and the vibration isolation effect of the compressor vibration isolation member 2 between the compressor 4 and the suspension bracket 1 is achieved.

[0035] Specifically, the compressor vibration isolation member 2 is a shaft sleeve structure, and the first connecting hole 211 is a threaded hole. The compressor 4 is connected to the first connecting hole 211 through a threaded connecting piece, so as to realize the fixed connection between the compressor 4 and the first inner core 21. The threaded connection ensures the connection strength between the compressor 4 and the suspension bracket 1.

[0036] In some optional embodiments, the compressor 4 can be connected through clamping or interference fit between the connecting piece and the first connecting hole 211, which can also realize the fixed connection between the compressor 4 and the first inner core 21.

[0037] As shown in Figures 4 to 6As shown in the embodiment of this application, the motor suspension assembly includes a first inner core 21 comprising a tubular portion 212 and a limiting portion 213 connected sequentially along its own extending direction. The diameter of the limiting portion 213 is larger than the diameter of the tubular portion 212. A first connecting hole 211 passes through the tubular portion 212 and the limiting portion 213 sequentially. A rubber bushing 22 is sleeved on the outer peripheral surface of the tubular portion 212, and the limiting portion 213 abuts against the end face of the rubber bushing 22.

[0038] In specific implementation, the limiting part 213 is located at the end of the first inner core 21 and abuts against the end face of the rubber bushing 22. When the compressor 4 causes its connecting parts to drive the first inner core 21 to move axially due to its own vibration, the axial force generated by the limiting part 213 is applied to the end face of the rubber bushing 22. The rubber bushing 22 prevents the limiting part 213 from directly hitting the end face of the first outer tube 23, thereby avoiding vibration caused by the impact of rigid materials and avoiding direct contact between the first inner core 21 and the first outer tube 23, blocking the transmission of vibration, and further improving the vibration isolation effect of the compressor vibration isolation component 2 between the compressor 4 and the suspension bracket 1.

[0039] Specifically, the limiting part 213 has a disc structure and is coaxially arranged with the tubular part 212 of the cylindrical structure. This shape arrangement allows the vibration of the first inner core 21 to be evenly transmitted to the rubber bushing 22 when it vibrates together with the compressor 4, so that the rubber bushing 22 can evenly buffer the vibration and improve the vibration damping effect between the first inner core 21 and the rubber bushing 22.

[0040] like Figures 4 to 6 As shown in the embodiment of this application, in the motor suspension assembly, at least a portion of the end of the rubber bushing 22 protrudes from the end face of the first outer tube 23, and the limiting portion 213 is provided at a distance from the end of the rubber bushing 22 to the end face of the first outer tube 23.

[0041] In specific implementation, at least a portion of the end of the rubber bushing 22 protrudes from the end face of the first outer tube 23, so that when the limiting part 213 is subjected to axial force and moves, it can only abut against the end of the rubber bushing 22, thereby keeping the limiting part 213 and the end face of the first outer tube 23 always separated, and there is no direct contact between the two, which blocks the transmission of vibration and further improves the vibration isolation effect of the compressor vibration isolation component 2 between the compressor 4 and the suspension bracket 1.

[0042] Specifically, the area of ​​the limiting part 213 is smaller than the cross-sectional area of ​​the rubber bushing 22, and the projection of the limiting part 213 on the end face of the rubber bushing 22 is within the end face range of the rubber bushing 22. This arrangement ensures that when the limiting part 213 undergoes axial movement to compress the rubber bushing 22, it will never exceed the coverage range of the rubber bushing 22, further avoiding direct contact between the limiting part 213 and the first outer tube 23.

[0043] In an alternative embodiment, the rubber bushing 22 comprises a blocking portion and a damping portion connected along the extension direction thereof, the blocking portion is in a disc structure, and is arranged between the limiting portion 213 and the end face of the first outer tube 23, for blocking the limiting portion 213 from directly contacting the end face of the first outer tube 23; the damping portion is in a cylindrical structure, and is sleeved on the outer circumferential surface of the tubular portion 212, and can damp the vibration between the tubular portion 212 and the inner surface of the first outer tube 23, and the cross-sectional diameter of the damping portion is smaller than the diameter of the blocking portion, so that when the rubber bushing 22 axially moves, the damping portion can abut against the end face of the first outer tube 23, to avoid the axial movement of the rubber bushing 22 being too large to cause the first inner core 21 to contact the first outer tube 23, thereby further ensuring the blocking effect of the rubber bushing 22 on the first inner core 21 and the first outer tube 23.

[0044] As shown in FIG. 1, the motor suspension assembly of the embodiment of the present application, wherein the sub-frame vibration isolation piece 3 comprises a second inner core 31, a flexible connecting piece 32 and a second outer tube 33 which are sequentially and sleevedly connected in a cylindrical structure, the second inner core 31 has a second connecting hole 311 penetratingly arranged along the extension direction thereof, and the sub-frame is connected to both ends of the sub-frame vibration isolation piece 3 through the second connecting hole 311, and the flexible connecting piece 32 is made of flexible material. Figure 7 As shown in FIG. 1, the motor suspension assembly of the embodiment of the present application, wherein the sub-frame vibration isolation piece 3 comprises a second inner core 31, a flexible connecting piece 32 and a second outer tube 33 which are sequentially and sleevedly connected in a cylindrical structure, the second inner core 31 has a second connecting hole 311 penetratingly arranged along the extension direction thereof, and the sub-frame is connected to both ends of the sub-frame vibration isolation piece 3 through the second connecting hole 311, and the flexible connecting piece 32 is made of flexible material.

[0045] In specific implementation, the flexible connecting piece 32 is sleeved on the outer circumferential surface of the second inner core 31, and the second outer tube 33 is sleeved on the outer circumferential surface of the flexible connecting piece 32, so as to form the interval arrangement between the second inner core 31 and the second outer tube 33, and the flexible connecting piece 32 made of flexible material is used for flexible connection therebetween. When the sub-frame is connected in the second connecting hole 311 of the second inner core 31, and the sub-frame mounting portion 12 of the suspension bracket 1 is connected with the second outer tube 33, the vibration transmitted from the suspension bracket 1 to the second outer tube 33 cannot be transmitted to the second inner core 31 under the damping effect of the flexible connecting piece 32, so that the sub-frame connected with the second inner core 31 is less affected by the vibration, and the vibration isolation effect of the sub-frame vibration isolation piece 3 on the suspension bracket 1 and the sub-frame is realized.

[0046] Since the second connecting hole 311 is a hole structure penetratingly arranged in the second inner core 31, both ends of the sub-frame vibration isolation piece 3 can be connected with the connecting piece and connected in cooperation, and the sub-frame can be connected with the connecting piece to both ends of the sub-frame vibration isolation piece 3, i.e. both sides of the suspension bracket 1, so that the connecting mode increases the connecting points between the sub-frame and the suspension bracket 1, thereby improving the connecting strength therebetween, and the connecting mode can be adapted to the shape of the sub-frame, so that the sub-frame is uniformly stressed at each connecting point.

[0047] In the embodiment of the present application, the auxiliary frame can be connected at both ends by a connecting piece penetrating through the second connecting hole 311. The length of the independent connecting piece is greater than the extension length of the second connecting hole 311, both ends of the connecting piece extend out of both ends of the second connecting hole 311 to connect with the partial auxiliary frames on both sides. The independent connecting piece has high overall strength, which ensures the connection strength between the auxiliary frame and the suspension bracket 1. Alternatively, two connecting pieces on both sides can be connected with the second connecting hole 311. The two connecting pieces can be penetrated into the second connecting hole 311 at both ends of the second connecting hole 311, thereby achieving the connection of both ends. The two connecting pieces have high flexibility and can be independently disassembled with the auxiliary frames on both sides of the suspension bracket 1, which facilitates disassembly and assembly operations.

[0048] Specifically, the auxiliary frame vibration isolation piece 3 is a shaft sleeve structure, the second connecting hole 311 is a threaded hole, and the auxiliary frame is connected to the second connecting hole 311 through a threaded connecting piece, thereby achieving the fixed connection between the auxiliary frame and the second inner core 31. The threaded connection ensures the connection strength between the auxiliary frame and the second inner core 31.

[0049] In some optional embodiments, the auxiliary frame can be connected by a clamping fit or interference fit between the connecting piece and the second connecting hole 311, which can also achieve the fixed connection between the auxiliary frame and the second inner core 31.

[0050] As shown in Figure 1 and Figure 7 , the motor suspension assembly of the embodiment of the present application, wherein the extension length of the flexible connecting piece 32 and the extension length of the second outer tube 33 are both less than the extension length of the second inner core 31, and both ends of the second inner core 31 protrude from the two side surfaces of the suspension bracket 1. The protruding arrangement of the end of the second inner core 31 relative to the side surface of the suspension bracket 1 facilitates the installation of the connecting piece. The operator does not need to insert the operating tool into the auxiliary frame mounting portion 12 for installation operation. The external installation operation has sufficient operating space, which reduces the installation difficulty of the connecting piece. Moreover, both ends of the second inner core 31 protrude from the two side surfaces of the suspension bracket 1. The operator can install the connecting piece from either side or from both sides at the same time, without any operational hindrance.

[0051] As shown in Figures 1 to 3 , the motor suspension assembly of the embodiment of the present application, wherein the compressor mounting portion 11 includes a plurality of first mounting holes 111 arranged at intervals, and the plurality of first mounting holes 111 collectively enclose a polygonal structure. The compressor vibration isolation piece 2 is connected with the first mounting hole 111 through an interference fit. The auxiliary frame mounting portion 12 includes at least one second mounting hole 121. The auxiliary frame vibration isolation piece 3 is connected with the second mounting hole 121 through an interference fit.

[0052] In specific implementation, the plurality of first mounting holes 111 of the compressor mounting portion 11 collectively enclose a polygonal structure, and when the compressor 4 is fixedly connected to the plurality of first mounting holes 111 through the plurality of connecting members, the plurality of connecting members can fix the compressor 4 in the polygonal structure, so that the fixed mounting of the compressor 4 has higher stability.

[0053] The compressor vibration isolation member 2 and the first mounting hole 111, and the auxiliary frame vibration isolation member 3 and the second mounting hole 121 are connected through interference fit, and when connected, the compressor vibration isolation member 2 only needs to be inserted into the first mounting hole 111, and the auxiliary frame vibration isolation member 3 only needs to be inserted into the second mounting hole 121, which is relatively simple to operate and reduces the installation difficulty of the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3.

[0054] The motor suspension assembly of the embodiment of the application, wherein the first mounting hole 111 and the second mounting hole 121 each have a plurality of protrusions protruding from the inner surface, the plurality of protrusions in the first mounting hole 111 abut against the outer circumferential surface of the compressor vibration isolation member 2, and the plurality of protrusions in the second mounting hole 121 abut against the outer circumferential surface of the auxiliary frame vibration isolation member 3.

[0055] In specific implementation, the plurality of protrusions inside the first mounting hole 111 and the second mounting hole 121 can further improve the effect of interference fit, so that the fixing effect between the compressor vibration isolation member 2 and the first mounting hole 111 and between the auxiliary frame vibration isolation member 3 and the second mounting hole 121 is better, and the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3 are less likely to come out of the respective mounting holes, thereby ensuring the installation stability of the compressor 4, the auxiliary frame, and the suspension bracket 1.

[0056] Specifically, in the first mounting hole 111 and the second mounting hole 121, the plurality of protrusions are arranged in the axial direction of the corresponding mounting hole, and when the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3 axially move, each protrusion arranged in sequence can generate a friction force, thereby ensuring the fixing effect of the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3; and each protrusion is in an annular structure and surrounds the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3, so that the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3 can be subjected to a larger friction force at each position in the circumferential direction, and the force is uniformly distributed at each position in the circumferential direction, thereby further improving the fixing effect of the compressor vibration isolation member 2 and the auxiliary frame vibration isolation member 3.

[0057] As Figures 1 to 3As shown, the motor suspension assembly of the embodiment of the present application, wherein the motor device mounting portion 13 comprises a plurality of mounting structures 131, the plurality of mounting structures 131 collectively enclose a polygonal structure, each mounting structure 131 comprises a first mounting section 1311 and a second mounting section 1312 arranged in sequence along the thickness direction of the suspension bracket 1, the first mounting section 1311 is in the form of a circular-arc-shaped groove structure, the second mounting section 1312 is in the form of a cylindrical structure, and the second mounting section 1312 has a third connecting hole 1313 arranged therethrough for mounting a connecting member connected to the motor device.

[0058] In specific implementation, the plurality of mounting structures 131 of the motor device mounting portion 13 collectively enclose a polygonal structure, and when the motor device is fixedly connected to the plurality of mounting structures 131 through the plurality of connecting members, the plurality of connecting members can fix the motor device in the polygonal structure, thereby making the fixed installation of the motor device have higher stability.

[0059] The first mounting section 1311 is in the form of a circular-arc-shaped groove structure, the second mounting section 1312 is in the form of a cylindrical structure, and the cylindrical structure of the second mounting section 1312 has a third connecting hole 1313 arranged therethrough, so that the motor device can be connected to the third connecting hole 1313 through the connecting member, thereby realizing fixed connection with the second mounting section 1312. When the connecting member is installed, it can be inserted into the third connecting hole 1313 from one side of the first mounting section 1311, and the groove structure of the first mounting section 1311 facilitates the insertion of the connecting member, thereby reducing the installation difficulty between the connecting member and the mounting structure 131. Moreover, the structure of the first mounting section 1311 improves the overall strength of the mounting structure 131, thereby avoiding the situation that the mounting structure 131 is broken due to excessive stress after the connecting member is installed.

[0060] The extension length of the first mounting section 1311 can be set according to the actual connection stress, and the mounting structure 131 can only have the second mounting section 1312 for corresponding connection with the connecting member.

[0061] Specifically, the third connecting hole 1313 is a threaded hole, and the connecting member is a bolt. The threaded portion of the bolt can be threadedly connected to the third connecting hole 1313, and the head portion of the bolt abuts against the step between the first mounting section 1311 and the second mounting section 1312. Therefore, the first mounting section 1311 provides sufficient installation space for the connecting member. In an alternative embodiment, the first mounting section 1311 is provided with a vibration isolator having the same structure as the compressor vibration isolator 2 and the auxiliary frame vibration isolator 3. The vibration isolator can isolate the vibration between the motor device and the suspension bracket 1, thereby avoiding the transmission of the vibration of the motor device to the suspension bracket 1, and further avoiding the excessive vibration of the auxiliary frame connected to the suspension bracket 1, which affects the use experience of the vehicle.

[0062] In an alternative embodiment, the mounting structure 131 can be a hole structure same as the first mounting hole 111 and the second mounting hole 121, to internally mount a vibration isolator same as the compressor vibration isolator 2 and the subframe vibration isolator 3 structure, which is simple in structure and can isolate the vibration of the motor device from the suspension bracket 1.

[0063] Specifically, the plurality of mounting structures 131 of the motor device mounting portion 13 are centrally arranged at one side edge of the suspension bracket 1, the second mounting hole 121 of the subframe mounting portion 12 is arranged at the other side edge of the suspension bracket 1, and the plurality of first mounting holes 111 of the compressor mounting portion 11 are centrally arranged between the motor device mounting portion 13 and the subframe mounting portion 12, which can disperse the motor device, the compressor 4 and the subframe to the suspension bracket 1, so that each of them has sufficient mounting space and does not interfere with each other. Moreover, the motor device and the subframe are large in size and are respectively mounted at the two side edges of the suspension bracket 1, which does not affect the installation of the compressor 4 in the middle of the suspension bracket 1, and the motor device and the compressor 4 are respectively mounted on the two side surfaces of the suspension bracket 1, which further avoids the interference between them.

[0064] The vehicle provided by the embodiment of the present application also includes the motor suspension assembly, the motor device, the compressor 4 and the subframe, the compressor 4 is mounted on one side of the suspension bracket 1 through the compressor vibration isolator 2 of the motor suspension assembly, the motor device is mounted on the other side of the suspension bracket 1, and the subframe is mounted on the suspension bracket 1 through the subframe vibration isolator 3 of the motor suspension assembly.

[0065] In the specific implementation, the vehicle provided by the present application includes the motor suspension assembly, the motor suspension assembly includes the suspension bracket 1, the compressor vibration isolator 2 and the subframe vibration isolator 3, the motor device is mounted on the motor device mounting portion 13 of the suspension bracket 1, the subframe is connected to the subframe mounting portion 12 of the suspension bracket 1 in a flexible manner through the subframe vibration isolator 3, and the compressor 4 is connected to the compressor mounting portion 11 of the suspension bracket 1 in a flexible manner through the compressor vibration isolator 2, so as to realize the integrated arrangement of the motor device, the compressor 4 and the subframe, and the installation space in the vehicle is reasonably utilized after the compressor 4 is mounted on the motor suspension assembly.

[0066] The vibration generated by the operation of the compressor 4 is buffered by the compressor vibration isolation member 2 after being transmitted to the compressor vibration isolation member 2, and only a small part of the vibration is transmitted to the suspension bracket 1 because of the flexible connection between the compressor vibration isolation member 2 and the compressor mounting portion 11, and the vibration of the suspension bracket 1 is further weakened under the buffering effect of the subframe vibration isolation member 3 because of the flexible connection between the subframe vibration isolation member 3 and the subframe mounting portion 12 of the suspension bracket 1, thereby realizing the secondary vibration isolation effect of the compressor 4, avoiding the excessive vibration of the subframe, and ensuring the use experience of the vehicle.

[0067] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one entity or action from another, without necessarily requiring or implying any such actual relationship or order between such entities or actions.
