[0032] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0036] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0037] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0038] An embodiment of the present application provides a suspension cushion assembly and a vehicle, wherein the suspension cushion assembly is used to connect the vehicle body and the motor. It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle model, the vehicle in the present application may be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models, as long as it has a motor.

[0039] When the motor is operating, it is prone to whistling due to its own high speed and the coupling between the structure. Severe whistling can cause a noticeable harsh noise inside the vehicle, affecting the driving experience. Therefore, the motor and the vehicle body are connected through a suspension cushion assembly. The suspension cushion assembly mainly has the following three functions:

[0040] 1.Fix the drive motor in the designed position to ensure the normal operation of the motor on the vehicle body;

[0041] 2. Reduce the vibration and noise transmitted from the motor to the vehicle body, and improve the driving comfort of the whole vehicle;

[0042] 3. Limit the large displacement of the motor to prevent the motor from colliding with other components in the cabin due to excessive displacement.

[0043] In related technologies, the suspension cushion assembly generally includes a suspension bracket and an electric drive suspension. The electric drive suspension is connected to the suspension bracket. The electric drive suspension mainly includes an exoskeleton, an inner skeleton and a main rubber. The exoskeleton is sleeved on the outside of the inner skeleton. The main rubber is located between the exoskeleton and the inner skeleton, and is vulcanized and connected to both the exoskeleton and the inner skeleton. Among them, the bracket is used to connect the motor, the electric drive suspension is used to connect the car body, and the main rubber is the main component for vibration reduction.

[0044] For some vehicles with high motor torque, the suspension cushion assembly is subject to heavy loads when the motor is operating, which can easily cause the main rubber component in the suspension cushion assembly to break due to excessive load. If the main rubber component breaks, the suspension cushion assembly will not be able to perform the three main functions mentioned above, resulting in the vehicle being unable to operate normally.

[0045] Currently, in order to avoid this situation, the common method is to increase the stiffness of the main rubber. However, due to the limitations of the process and the rubber material itself, the stiffness of the main rubber has an upper limit. At the same time, after the stiffness of the main rubber increases to a certain range, the improvement in reliability is not obvious. Increasing the stiffness of the main rubber will also reduce the vibration isolation capability of the suspension cushion assembly.

[0046] In this regard, embodiments of the present application provide a suspension cushion assembly and a vehicle. The suspension cushion assembly comprises a suspension bracket and at least two first vibration isolation assemblies. The suspension bracket is used to connect to a motor. The first vibration isolation assembly includes a first exoskeleton, a first elastic member, and a first endoskeleton, arranged sequentially from the outside to the inside. The first elastic member connects the first exoskeleton and the first endoskeleton, and the first endoskeleton is connected to the suspension bracket. The first exoskeleton is used to connect to the vehicle body, thereby providing vibration isolation through the first elastic member. Furthermore, at least two first vibration isolation assemblies are provided on a single suspension bracket, thereby reducing the load transmitted from the motor to a single first vibration isolation assembly via the suspension bracket by at least half. This effectively reduces the strength requirements of a single first vibration isolation assembly for a high-torque output motor. This reduces the stiffness of the first elastic member and allows it to be maintained within an appropriate vibration isolation range, thereby effectively improving the vibration isolation effect of the suspension cushion assembly. Furthermore, the at least two first vibration isolation assemblies share a single suspension bracket. This effectively reduces costs compared to separately adding existing suspension cushion assemblies to reduce the risk of main rubber fracture, and also facilitates assembly with the vehicle body and motor.

[0047] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the suspension cushion assembly includes a suspension bracket 100 and at least two first vibration isolation assemblies 200 .

[0049] The first vibration isolation component 200 is arranged on the suspension bracket 100. The first vibration isolation component 200 includes a first external skeleton 210, a first elastic member 220 and a first internal skeleton 230. The first internal skeleton 230 is provided with a first connecting hole. The first internal skeleton 230 is inserted into the first connecting hole. The first elastic member 220 is used to connect the first external skeleton 210 and the first internal skeleton 230. The first internal skeleton 230 is used to connect with the suspension bracket 100, and the suspension bracket 100 is used to connect the motor.

[0050] It is understandable that the first elastic member 220 may be a common rubber or other material having elasticity that can reduce vibration, and this embodiment does not limit this.

[0051] For example, the first elastic member 220 is made of NR (natural rubber), which has good tear strength and elongation, and can effectively isolate and reduce noise and vibration on the powertrain side.

[0052] Among them, the first elastic member 220 can be set as a sleeve-like structure, directly sleeved on the outside of the first inner skeleton 230, and then the inner surface is vulcanized and connected to the first inner skeleton 230, and the outer surface is vulcanized and connected to the first outer skeleton 210, thereby effectively reducing the vibration energy transmitted from the side of the suspension bracket 100.

[0053] Of course, the first elastic member 220 may also be configured in other shapes, as long as it can be stably connected to the first inner frame 230 and the first outer frame 210 to effectively isolate vibrations therebetween. This embodiment does not limit this.

[0054] In this embodiment, at least two first vibration isolation assemblies 200 are arranged on the same suspension bracket 100. During the operation of the motor, the electric drive load can be shared by the first vibration isolation assembly 200, so that the force applied to a single first vibration isolation assembly 200 is reduced by at least half compared with a conventional suspension cushion assembly. Therefore, the suspension cushion assembly can adapt to high-torque motors without increasing the stiffness of the first elastic member 220, that is, the vibration isolation performance of the suspension cushion assembly will not be reduced, and it can adapt to the use requirements of high-torque motors. At the same time, at least two first vibration isolation assemblies 200 share one suspension bracket 100, which can reduce the number of suspension brackets 100 set, which is beneficial to reducing costs and facilitating installation.

[0055] In some embodiments of the present application, two first vibration isolation assemblies 200 are provided, and are symmetrically arranged at both ends of the suspension bracket 100. Of course, the suspension bracket 100 is preferably also symmetrically arranged along its midline. This allows the two first vibration isolation assemblies 200 to better evenly distribute the electric drive load, avoiding the situation where one first vibration isolation assembly 200 is subjected to excessive force while the other first vibration isolation assembly 200 is subjected to less force and cannot fully utilize its strength, thereby avoiding the situation where the performance of the suspension cushion assembly is over-performing. At the same time, this method also makes the two first vibration isolation assemblies 200 more evenly stressed. When stimulated by the motor, the response consistency of the two first vibration isolation assemblies 200 will be better, which can significantly improve the vibration isolation effect of the suspension cushion assembly.

[0056] During the use of the suspension cushion assembly, the problem of motor howling is generally improved by reducing the stiffness of the main rubber of the suspension cushion assembly. However, reducing the stiffness of the main rubber of the suspension cushion assembly has limited effect on improving this problem. At the same time, reducing the stiffness of the main rubber of the suspension cushion assembly will also reduce the reliability strength of the main rubber, causing the main rubber to be more likely to break under large loads.

[0057] In this regard, in some embodiments of this application, see Figure 1 As shown, the suspension cushion assembly further includes at least two second vibration isolation components 300 , which are used to connect the motor and the suspension bracket 100 so as to consume the vibration energy transmitted from the motor side through the second vibration isolation components 300 .

[0058] Specifically, the second vibration isolation component 300 is located between the motor and the suspension bracket 100. The vibration energy generated when the motor is running is first transmitted to the second vibration isolation component 300, and part of the vibration energy is consumed by the second vibration isolation component 300. The remaining vibration energy is transmitted to the first vibration isolation component 200 through the suspension bracket 100 and consumed by the first vibration isolation component 200, thereby achieving a double vibration isolation effect through the first vibration isolation component 200 and the second vibration isolation component 300, thereby effectively improving the vibration isolation capability of the suspension cushion assembly.

[0059] In some embodiments of the present application, the second vibration isolation assembly 300 includes a second exoskeleton 310, a second endoskeleton 330 and a second elastic member 320. The second exoskeleton 310 is provided with a second connecting hole, and the second endoskeleton 330 is inserted into the second connecting hole. It can also be understood that the second exoskeleton 310 is sleeved on the outside of the second endoskeleton 330. The second elastic member 320 is used to connect the second endoskeleton 330 and the second exoskeleton 310. The second exoskeleton 310 is used to connect the suspension bracket 100, and the second endoskeleton 330 is used to connect the motor. Of course, corresponding threaded holes can be opened on the second endoskeleton 330 to rigidly connect it to the motor through bolts.

[0060] It is understandable that the second elastic member 320 may be a common rubber or other material having elasticity that can reduce vibration, and this embodiment does not limit this.

[0061] For example, the second elastic member 320 is made of NR (natural rubber), which has good tear strength and elongation, and can effectively isolate and reduce noise and vibration on the powertrain side.

[0062] Among them, the second elastic member 320 can be set as a sleeve-like structure, directly sleeved on the outside of the second inner skeleton 330, and then the inner surface is vulcanized and connected to the second inner skeleton 330, and the outer surface is vulcanized and connected to the second outer skeleton 310, thereby effectively reducing the vibration energy transmitted from the side of the suspension bracket 100.

[0063] Of course, the second elastic member 320 may also be configured in other shapes, as long as it can be stably connected to the second inner frame 330 and the second outer frame 310 to effectively isolate vibrations therebetween. This embodiment does not limit this.

[0064] Furthermore, the first inner frame 230 and the second inner frame 330 can be manufactured using a drawn aluminum process, which offers lower production costs while still meeting practical requirements. The first outer frame 210 can be made of plastic, reducing costs while also meeting practical requirements, while the second outer frame 310 can be made of sheet metal. The suspension bracket 100 can be manufactured using a high-pressure, integrated aluminum casting process to effectively connect with the other components.

[0065] Further, see Figure 7 As shown, in order to facilitate the connection between the second vibration isolation assembly 300 and the suspension bracket 100 , the suspension bracket 100 is provided with at least one first mounting hole 150 , and the second exoskeleton 310 is correspondingly inserted into the first mounting hole 150 .

[0066] The second exoskeleton 310 can be connected to the first mounting hole 150 by interference fit. During assembly, the second exoskeleton 310 only needs to be pressed into the first mounting hole 150, which can reduce the difficulty of installation.

[0067] At the same time, the first mounting hole 150 is preferably a through hole, and a through hole is provided on the second inner frame 330 so that bolts can be screwed into the through holes on the second inner frame 330 to connect the second inner frame 330 and the motor.

[0068] In some embodiments of this application, see Figure 7 、 Figure 8 and Figure 9As shown, the suspension bracket 100 includes a triangular bracket body 110 , and the bracket body 110 is provided with a mounting portion 120 at each corner of the triangle, and each mounting portion 120 is provided with a second vibration isolation assembly 300 .

[0069] Specifically, configuring the bracket body 110 in a triangular shape effectively improves its stability, allowing it to better bear the load. Currently, commonly used motors are typically cast aluminum motors. Connecting them via only two first vibration isolation assemblies 200 can easily damage the motor. Providing three first vibration isolation assemblies 200 reduces the number of connection points and significantly reduces the probability of motor damage.

[0070] In addition, in order to avoid stress concentration, the bracket body 110 can be made to have smooth transitions at all locations to avoid sharp points, thereby avoiding stress concentration and further improving the strength of the suspension bracket 100.

[0071] In some embodiments of the present application, the bracket body 110 is an isosceles triangle, and a connecting portion 160 is provided on the mounting portion 120 located at the two bottom corners of the bracket body 110. The connecting portion 160 extends at least partially along the height direction of the bracket body 110 to the outside of the mounting portion 120, and the connecting portion 160 is correspondingly connected to a first vibration isolation assembly 200.

[0072] Specifically, a connecting portion 160 is added and made to protrude to the outside of the mounting portion 120, so that the connection point between the first vibration isolation component 200 and the connecting portion 160 is higher than the mounting portion 120, which facilitates the processing of the connecting portion 160. With lower processing costs and time costs, the connection points of the two first vibration isolation components 200 with the connecting portion 160 are ensured to be at the same vertical height, so that the two first vibration isolation components 200 can better share the load. When the first vibration isolation component 200 and the suspension bracket 100 are axially symmetrically arranged relative to the central axis of the suspension bracket 100, it is also more convenient to perform mechanical testing, which can further reduce production costs.

[0073] Further, see Figure 7 As shown, the connecting portion 160 is provided with a second mounting hole 140 , and the first inner frame 230 is connected to the second mounting hole 140 correspondingly through bolts.

[0074] Specifically, a mounting hole can be provided in the middle of the first inner frame 230 for inserting a bolt, thereby locking the first inner frame 230 to the connecting portion 160. At the same time, to facilitate positioning of the first vibration isolation assembly 200 during assembly and prevent it from rotating, two retaining grooves can be provided opposite each other above the mounting hole on the first inner frame 230. The tooling used during assembly cooperates with the retaining grooves to position the first vibration isolation assembly 200, preventing it from rotating, thereby limiting the positional relationship between the first vibration isolation assembly 200 and the suspension bracket 100.

[0075] In some embodiments of this application, see Figure 10 and Figure 11 As shown, a limiting pad 211 is provided at one end of the first exoskeleton 210 adjacent to the suspension bracket 100, and the limiting pad 211 at least partially extends between the first exoskeleton 210 and the suspension bracket 100 to limit the distance between the first exoskeleton 210 and the suspension bracket 100 through the limiting pad 211.

[0076] Among them, the limiting pad 211 can be set on one side or both sides of the first exoskeleton 210, extending toward one end of the first exoskeleton 210 toward the suspension bracket 100, and at least part of the projection of the limiting pad 211 can extend into the gap between the first exoskeleton 210 and the suspension bracket 100, so that the first exoskeleton 210 can be limited by the limiting pad 211 to avoid contact between the first exoskeleton 210 bracket and the suspension bracket 100.

[0077] Furthermore, a limiting portion 130 is provided on the suspension bracket 100 , the limiting cushion 211 is arranged opposite to the limiting portion 130 , and a projection of the limiting cushion 211 in the extension direction of the first exoskeleton 210 is located within the limiting portion 130 .

[0078] Specifically, in order to reduce the weight of the suspension bracket 100, the bracket body 110 is only formed into a triangular structure as a whole, but the thickness of each part thereof is not too large, and is smaller than the diameter of the first outer skeleton 210. In order to enable the limiting pad 211 to effectively limit the position, the limiting pad 211 has a certain length in the thickness direction of the bracket body 110. In order to ensure that the limiting pad 211 can fully contact the suspension bracket 100, a limiting portion 130 extending to the outside of the bracket body 110 can be set only at the position where the bracket body 110 and the limiting pad 211 are relative to each other, and the length of the limiting portion 130 in the thickness direction of the bracket body 110 is greater than the length of the limiting pad 211 to avoid the limiting pad 211 extending outside the limiting portion 130.

[0079] An embodiment of the present application also provides a vehicle, comprising a vehicle body, a motor, and the suspension cushion assembly of the above embodiment, wherein the suspension cushion assembly is used to connect the motor and the vehicle body.
