Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to an auxiliary suspension bracket assembly and a vehicle. Background Art

[0002] With the recent rise in popularity of new energy vehicles, more and more vehicles are replacing traditional fuel engines with electric drive motors in their powertrains, and are equipped with main mount bracket assemblies. The main mount bracket assembly not only secures the drive motor to the vehicle's designated location, but also reduces vibration transmitted to the vehicle body during operation and limits the motor's range of motion under high torque output. Because drive motors often output greater torque than traditional fuel engines, the main rubber components within the main mount bracket assembly can displace significantly under the high torque of the drive motor, making them susceptible to breakage or detachment.

[0003] In the prior art, the rigidity of the main rubber is usually designed to be larger to improve the reliability and strength of the main rubber and prevent it from breaking or falling off.

[0004] However, the above technical means will increase the vibration of the entire vehicle and affect driving comfort. Utility Model Content

[0005] In view of this, the embodiments of the present application provide an auxiliary suspension bracket assembly and a vehicle, which can effectively solve the problem that the main rubber inside the main suspension bracket assembly is easily broken or detached under the action of the high torque of the driving motor.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0007] In one aspect, an embodiment of the present application provides an auxiliary suspension bracket assembly for connecting a vehicle body and a powertrain, the auxiliary suspension bracket assembly comprising:

[0008] The vehicle body connection mechanism includes: a first bracket and a first buffer device, wherein the first bracket is connected to the vehicle body, and the first buffer device is fixed to the first bracket;

[0009] A powertrain connection mechanism, comprising: a second bracket and a second buffer device, the second bracket being connected to the powertrain, the second bracket being opposite to and spaced from the first bracket along a first direction, and the second buffer device being fixed to the second bracket;

[0010] The first buffer device and the second buffer device have a first mating state and a second mating state, wherein in the first mating state, the first buffer device is separated from the second buffer device, and in the second mating state, the first buffer device is in contact with the second buffer device to limit the second buffer device.

[0011] According to the auxiliary suspension bracket assembly of the embodiment of the present application, when the vehicle's powertrain output torque is small, that is, the displacement of the powertrain is small, the displacement of the second bracket connected to the powertrain is small, at this time the first buffer device and the second buffer device are in a separated state, and the auxiliary suspension bracket assembly does not participate in the work; when the vehicle's powertrain output torque is large, that is, the displacement of the powertrain is large, the displacement of the second bracket connected to the powertrain is large, the second buffer device follows the second bracket to move toward the direction close to the first buffer device, and squeezes each other with the first buffer device. At this time, the mutual squeezing of the first buffer device and the second buffer device will generate a reaction force, which hinders the further displacement of the powertrain, thereby ensuring that the displacement range of the main rubber of the main suspension bracket assembly is controllable, avoiding excessive displacement of the main rubber, which is easy to break or fall off.

[0012] In a possible implementation, the first buffer device has a buffer cavity on its inner side;

[0013] The second buffer device includes: a first buffer portion and a second buffer portion, the first buffer portion is fixedly connected to the second bracket, the first buffer portion and the first buffer device are opposite and spaced apart along the first direction, one end of the second buffer portion is fixedly connected to the first buffer portion, and the other end extends into the inner side of the buffer cavity and is spaced apart from the inner wall of the buffer cavity.

[0014] In the second fitting state, the first buffer portion is press-fitted with the end portion of the first buffer device, and / or the second buffer portion is press-fitted with the inner wall of the buffer cavity.

[0015] In this way, the contact area between the first buffer device and the second buffer device is increased, which not only effectively disperses the abutting pressure between the first buffer device and the second buffer device, but also improves the abutting strength between the first buffer device and the second buffer device, ensuring that further displacement of the powertrain can be hindered.

[0016] In a possible implementation, the first buffer device includes:

[0017] a first frame fixedly disposed on the first bracket, wherein the inner side of the first frame defines the buffer cavity;

[0018] The first buffer pad covers and is fixed to the inner surface of the buffer cavity.

[0019] In this way, the overall strength of the first buffer device can be effectively improved, thereby preventing the first buffer device from being damaged during the operation of the auxiliary suspension bracket assembly.

[0020] In a possible implementation, a mounting cavity is provided on a side of the first bracket facing the second bracket, the mounting cavity is adapted to the first frame, and the first frame is fixed in the mounting cavity; and / or,

[0021] The first buffer pad is a rubber member; and / or,

[0022] The first buffer pad is connected to the first skeleton by vulcanization.

[0023] In this way, there is no need to reserve installation space for the first frame, making the overall structure of the first buffer device more compact; the first buffer pad is made into a rubber part, and the rigid collision between the first buffer device and the second buffer device is transformed into an elastic collision, thereby extending the service life of the first buffer device and the second buffer device; and the first buffer pad is vulcanized and then connected to the first frame. Since vulcanization can increase the adhesion of the first buffer pad, it is more firmly connected to the first frame.

[0024] In a possible implementation, the second buffer device includes:

[0025] a second frame, comprising a first supporting portion and a second supporting portion, the first supporting portion being opposite to and spaced from the first buffer device along the first direction, the second supporting portion being columnar, one end of the second supporting portion being fixedly connected to the first supporting portion, and the other end of the second supporting portion extending into the inner side of the buffer cavity and spaced from the inner wall of the buffer cavity;

[0026] A second buffer pad at least covers an outer surface of the second supporting portion.

[0027] Similarly, the overall strength of the second buffer device can be effectively improved to avoid damage to the second buffer device during operation of the auxiliary suspension bracket assembly; the second skeleton is composed of a first support part and a second support part, and the first support part can increase the contact area between the second skeleton and the second bracket, that is, the contact area between the second buffer device and the second bracket, effectively dispersing the abutting pressure between the second buffer device and the second bracket while improving the abutting strength between the second buffer device and the second bracket. The shape of the second support part is adapted to the buffer cavity to ensure that the first buffer device and the second buffer device can fit tightly in the second matching state; and the first support part and the second support part cooperate with each other to limit the second buffer device in the X, Y and Z directions.

[0028] In a possible implementation, the second buffer pad further covers a side surface of the first support portion facing the first buffer device.

[0029] In this way, the coverage area of the second buffer pad on the second frame is expanded, so that the first buffer device and the second buffer device can always be in contact through the second buffer pad, thereby avoiding direct collision between the first buffer device and the second buffer device, which may cause damage to both.

[0030] In a possible implementation, the second buffer pad is provided with a plurality of buffer protrusions; and / or,

[0031] The second buffer pad is a rubber member; and / or,

[0032] The second buffer pad is connected to the second skeleton by vulcanization.

[0033] Multiple buffer protrusions can form a buffer zone between the contact surfaces of the first buffer device and the second buffer device, preventing abnormal noise and a sense of frustration due to excessive impact at the moment when the first buffer device contacts the second buffer device; similarly, the second buffer pad is made into a rubber part, and the rigid connection between the first buffer device and the second buffer device is changed to an elastic connection, thereby extending the service life of the first buffer device and the second buffer device.

[0034] In a possible implementation, the second skeleton is provided with a first connection hole, and the second bracket is provided with a second connection hole.

[0035] The powertrain connection mechanism further includes a fastening connector, and the second buffer device and the second bracket are connected through the fastening connector through the first connection hole and the second connection hole.

[0036] The fastening connector is passed through the first connection hole and the second connection hole to achieve the connection and fixation between the second buffer device and the second bracket.

[0037] In a possible implementation, a positioning groove is provided on the periphery of the first connecting hole, and a positioning protrusion is provided on the periphery of the second connecting hole. The positioning protrusion is suitable for being embedded in the positioning groove to position and cooperate the second buffer device with the second bracket.

[0038] Before the fastening connector is passed through the first connecting hole and the second connecting hole, the positioning groove and the positioning protrusion cooperate with each other and position the relative positions of the second buffer device and the second bracket to prevent the second buffer device from being offset or misplaced during subsequent connection or even use.

[0039] On the other hand, an embodiment of the present application further provides a vehicle, comprising:

[0040] body;

[0041] Powertrain;

[0042] a main suspension bracket assembly, wherein the main suspension bracket assembly is connected to the vehicle body and the powertrain respectively;

[0043] The auxiliary suspension bracket assembly described in any one of the possible implementations above is connected to the vehicle body and the powertrain, respectively, and is constructed so that when the powertrain is displaced, the first buffer device contacts the second buffer device to limit the second buffer device.

[0044] By providing an auxiliary suspension bracket assembly, the pressure on the main suspension bracket assembly is shared, thereby preventing the main rubber inside the main suspension bracket assembly from breaking or falling off due to excessive displacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] 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.

[0074] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0075] 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.

[0077] 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.

[0078] 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.

[0079] With the recent rise in popularity of new energy vehicles, more and more vehicles are replacing traditional fuel engines with electric drive motors in their powertrains, and are equipped with main mount bracket assemblies. The main mount bracket assembly not only secures the drive motor to the vehicle's designated location, but also reduces vibration transmitted to the vehicle body during operation and limits the motor's range of motion under high torque output. Because drive motors often output greater torque than traditional fuel engines, the main rubber components within the main mount bracket assembly can displace significantly under the high torque of the drive motor, making them susceptible to breakage or detachment.

[0080] In the prior art, the rigidity of the main rubber is usually designed to be larger to improve the reliability and strength of the main rubber and prevent it from breaking or falling off.

[0081] However, the above technical means will increase the vibration of the entire vehicle and affect driving comfort.

[0082] Based on this, embodiments of the present application provide an auxiliary suspension bracket assembly and a vehicle. When the vehicle's powertrain output torque is low, i.e., the powertrain displacement is small, and the second bracket connected to the powertrain is also displaced. At this time, the first and second buffer devices are separated, and the auxiliary suspension bracket assembly does not participate in operation. When the vehicle's powertrain output torque is high, i.e., the powertrain displacement is large, and the second bracket connected to the powertrain is also displaced, the second buffer device follows the second bracket and moves toward the first buffer device, squeezing against the first buffer device. At this time, the squeezing between the first and second buffer devices generates a reaction force, hindering further displacement of the powertrain, thereby ensuring that the displacement range of the main rubber of the main suspension bracket assembly is controllable, preventing the main rubber from excessively displacing and easily breaking or falling off.

[0083] The following detailed description of the technical solution of the present application is provided with reference to the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0084] Reference Figures 1 to 6 An embodiment of the present application provides an auxiliary suspension bracket assembly for connecting a vehicle body and a powertrain. The auxiliary suspension bracket assembly includes a body connection mechanism and a powertrain connection mechanism.

[0085] Among them, the body connection mechanism may include a first bracket 100 and a first buffer device 200. The first bracket 100 is connected to the body. The first bracket 100 can be directly connected to the body or connected through an intermediate adapter. The first bracket 100 can provide installation support for the buffer device on the body side, namely the first buffer device 200, so that the first buffer device 200 is fixed to the first bracket 100.

[0086] The powertrain connection mechanism can include a second bracket 300 and a second buffer device 400. The second bracket 300 is connected to the powertrain, which can be an engine or an electric motor. The second bracket 300 is spaced apart from and opposite to the first bracket 100 along a first direction. The second bracket 300 provides mounting support for the powertrain-side buffer device, namely the second buffer device 400, thereby facilitating the securing of the second buffer device 400 to the second bracket 300.

[0087] The first buffer device 200 and the second buffer device 400 have a first mating state and a second mating state. In the first mating state, the first buffer device 200 and the second buffer device 400 are separated. In the second mating state, the first buffer device 200 and the second buffer device 400 are in contact to limit the second buffer device 400.

[0088] It can be understood that in the present application, there is no restriction on the connection method between the first bracket 100 and the vehicle body, and the connection method between the second bracket 300 and the powertrain. It can be a fixed connection such as welding, or a detachable connection such as bolt connection. The operator can choose according to the actual situation to ensure that the first bracket 100 is fixed on the vehicle body and the second bracket 300 is fixed on the powertrain.

[0089] In specific implementation, when the vehicle is in a working condition where the powertrain output torque is small or the bump is small, that is, the displacement of the powertrain is small, the displacement of the second bracket 300 connected to the powertrain is small, at this time the first buffer device 200 and the second buffer device 400 are in a separated state, the auxiliary suspension bracket assembly does not participate in the work, and the buffering between the vehicle body and the powertrain is mainly undertaken by the main suspension bracket assembly, which is beneficial to reducing the noise of the whole vehicle; when the vehicle is in a working condition where the powertrain output torque is large or the bump is large, such as climbing or accelerating, that is, the displacement of the powertrain is large, the displacement of the second bracket 300 connected to the powertrain is large, the second buffer device 40 0 moves along with the second bracket 300 toward the first buffer device 200 and squeezes against the first buffer device 200. At this time, the mutual squeezing of the first buffer device 200 and the second buffer device 400 generates a reaction force, which hinders the further displacement of the powertrain. This process is equivalent to increasing the stiffness of the suspension cushion assembly (i.e., the main rubber) of the main suspension bracket assembly. The greater the stiffness of the suspension cushion assembly, the smaller the displacement of the powertrain under the same torque output. After reducing the displacement of the powertrain, the displacement range of the main rubber of the main suspension bracket assembly can be ensured to be controllable, avoiding excessive displacement of the main rubber, which is prone to breakage or falling off.

[0090] Compared with the prior art, the auxiliary suspension bracket assembly provided in the embodiment of the present application adjusts the stiffness of the main rubber, while reducing the vibration of the entire vehicle and ensuring driving comfort, it also shares the pressure on the main suspension bracket assembly and effectively protects the main rubber of the main suspension bracket assembly.

[0091] In some embodiments of the present application, reference is made to Figures 1 to 6 The first buffer device 200 has a buffer cavity 211 on its inner side; the second buffer device 400 may include: a first buffer portion and a second buffer portion, wherein the first buffer portion is fixedly connected to the second bracket 300, the first buffer portion and the first buffer device are opposite and spaced apart along the first direction, one end of the second buffer portion is fixedly connected to the first buffer portion, and the other end extends into the inner side of the buffer cavity 211 and is spaced apart from the inner wall of the buffer cavity 211. In the second mating state, the first buffer portion is press-fitted with the end of the first buffer device 200, and / or the second buffer portion is press-fitted with the inner wall of the buffer cavity 211.

[0092] This increases the contact area between the first and second shock absorbers 200 and 400, effectively dispersing the abutment pressure between the two devices while also increasing the abutment strength between them, ensuring that further displacement of the powertrain is prevented. It can be understood that the contact between the first shock absorber 200 and the first shock absorber 200 limits the freedom and displacement of the powertrain in the first direction, while the contact between the second shock absorber 200 and the first shock absorber 200 limits the radial displacement of the powertrain in the buffer cavity 211.

[0093] In some embodiments of the present application, reference is made to Figures 1 to 6 The first cushioning device 200 includes a first frame 210 and a first cushioning pad 220. The first frame 210 can be fixedly mounted on the first bracket 100. The inner side of the first frame 210 defines a cushioning cavity 211, which provides mounting support for the first cushioning pad 220. The first cushioning pad 220 covers and is fixed to the inner surface of the cushioning cavity 211, primarily providing a cushioning function.

[0094] The provision of the first frame 210 can effectively improve the overall strength of the first buffer device 200 and prevent the first buffer device 200 from being damaged during the operation of the auxiliary suspension bracket assembly.

[0095] In the specific implementation, an interference fit is adopted between the first skeleton 210 and the first bracket 100 to improve the connection strength between the first skeleton 210 and the first bracket 100, to prevent the first skeleton 210 from falling off from the first bracket 100 during the operation of the auxiliary suspension bracket assembly, and to prevent the first skeleton 210 from being displaced axially or circumferentially relative to the first bracket 100.

[0096] In some embodiments of the present application, reference is made to Figures 1 to 6 A mounting cavity 110 is provided on the side of the first bracket 100 facing the second bracket 300. The mounting cavity 110 is adapted to the first skeleton 210. The first skeleton 210 is fixed in the mounting cavity 110. For example, the cross-sectional shape of the mounting cavity 110 can be circular, square or any other shape. Correspondingly, the first skeleton 210 can be cylindrical, square cylindrical or other shapes. The first skeleton 210 and the cavity wall of the mounting cavity 110 can be interference fit.

[0097] Optionally, the first buffer pad 220 is a rubber member, so that the first buffer pad 220 can be guaranteed to have sufficient elasticity to better play a buffering role and ensure its own service life.

[0098] Optionally, the first buffer pad 220 is connected to the first skeleton 210 by vulcanization.

[0099] In this way, there is no need to reserve installation space for the first frame 210 , making the overall structure of the first buffer device 200 more compact.

[0100] It should also be understood that, in this application, there are no restrictions on the material of the first cushion 220 or the method of connection between the first cushion 220 and the first frame 210. Specifically, in the above embodiment, the first cushion 220 is configured as a rubber member to absorb the impact of the moment when the first cushioning device 200 and the second cushioning device 400 come into contact, ensuring the stability of the connection and extending the service life of the first cushioning device 200 and the second cushioning device 400. The first cushion 220 is vulcanized before being connected to the first frame 210. Vulcanization can increase the adhesion of the first cushion 220, making its connection to the first frame 210 more secure.

[0101] In some embodiments of the present application, reference is made to Figures 1 to 6 as well as Figure 8 The second buffer device 400 includes: a second frame 410 and a second buffer pad 420. The second frame 410 can provide installation support for the second buffer pad 420. The second frame 410 can include a first support portion 411 and a second support portion 412. The first support portion 411 is opposite to and spaced from the first buffer device 200 along a first direction. Exemplarily, the first support portion 411 can be disc-shaped or trumpet-shaped, with an outer diameter greater than the inner diameter of the buffer cavity 211. The second support portion 412 is columnar, with one end of the second support portion 412 fixedly connected to the first support portion 411 and the other end extending into the inner side of the buffer cavity 211 and spaced from the inner wall of the buffer cavity 211. The second buffer pad 420 at least covers the outer surface of the second support portion 412.

[0102] The provision of the second frame 410 effectively improves the overall strength of the second cushioning device 400, preventing damage to the second cushioning device 400 during operation of the auxiliary suspension bracket assembly. Furthermore, in a specific implementation, a plurality of ribs are provided on the contact surface between the second frame 410 and the second bracket 300 (i.e., the surface of the first support portion 411 facing the second bracket 300). The ribs may be spaced apart circumferentially around the second frame 410, and each rib may extend radially from the first support portion 411 to enhance the strength of the second frame 410.

[0103] The second skeleton 410 is composed of a first support portion 411 and a second support portion 412. The first support portion 411 can increase the contact area between the second skeleton 410 and the second bracket 300, that is, the contact area between the second buffer device 400 and the second bracket 300, effectively dispersing the abutting pressure between the second buffer device 400 and the second bracket 300, while improving the abutting strength between the second buffer device 400 and the second bracket 300. The shape of the second support portion 412 is adapted to the buffer cavity 211 to ensure that the first buffer device 200 and the second buffer device 400 can fit tightly in the second matching state; the first support portion 411 and the second support portion 412 cooperate with each other to realize the second buffer device 400 in X (reference Figure 2 X direction), Y (reference Figure 2 Y direction), Z (reference Figure 2 Limit in three directions (Z direction).

[0104] In some embodiments of the present application, reference is made to Figure 1 、 Figure 2 and Figure 5 The second buffer pad 420 also covers a side surface of the first support portion 411 facing the first buffer device 200 .

[0105] In this way, the coverage area of the second cushion 420 on the second frame 410 is expanded, so that the first cushioning device 200 and the second cushioning device 400 can always contact each other through the second cushion 420, thereby avoiding direct collision between the first cushioning device 200 and the second cushioning device 400, which may cause damage to both.

[0106] In some embodiments of the present application, reference is made to Figures 1 to 6 as well as Figure 9 and Figure 10 The second cushioning pad 420 is provided with a plurality of cushioning protrusions 421. The plurality of cushioning protrusions 421 can form a buffer zone between the contact surfaces of the first cushioning device 200 and the second cushioning device 400, thereby preventing abnormal noise and jerking caused by excessive impact at the moment of contact between the first cushioning device 200 and the second cushioning device 400.

[0107] Optionally, the second cushion 420 is a rubber member. It is also understood that, in this application, there are no restrictions on the material of the second cushion 420 or the connection method between the second cushion 420 and the second frame 410. Specifically, in the above embodiment, the second cushion 420 is configured as a rubber member to absorb the impact of the first cushioning device 200 and the second cushioning device 400 at the moment of contact, ensuring the stability of the connection and extending the service life of the first cushioning device 200 and the second cushioning device 400.

[0108] Optionally, the second cushion pad 420 is vulcanized and connected to the second frame 410. After the second cushion pad 420 is vulcanized, it is connected to the second frame 410. Since vulcanization can increase the adhesion of the second cushion pad 420, it is more firmly connected to the second frame 410.

[0109] In some embodiments of the present application, reference is made to Figures 1 to 8 A first connecting hole 413 is provided on the second skeleton 410, and a second connecting hole 310 is provided on the second bracket 300. The powertrain connection mechanism may further include: a fastening connector 500, and the second buffer device 400 and the second bracket 300 are connected through the fastening connector 500 through the first connecting hole 413 and the second connecting hole 310.

[0110] The fastening connector 500 is passed through the first connecting hole 413 and the second connecting hole 310 to achieve the connection and fixation between the second buffer device 400 and the second bracket 300. For example, the fastening connector 500 can be a bolt, and the first connecting hole 413 and the second connecting hole 310 can be screw holes. The connection and fixation between the second buffer device 400 and the second bracket 300 can be achieved by screwing the bolt into the screw hole. In addition, the connection method between the second buffer device 400 and the second bracket 300 includes but is not limited to threaded connection, snap connection, welding or other forms of mechanical connection. The specific connection method can be adaptively selected according to actual conditions and is not limited here.

[0111] In some embodiments of the present application, reference is made to Figures 1 to 8 A positioning groove 411a is provided around the periphery of the first connecting hole 413. The cross-section of the positioning groove 411a can be U-shaped, semicircular or other shapes. A positioning protrusion 320 is provided around the periphery of the second connecting hole 310. The positioning protrusion 320 is suitable for embedding in the positioning groove 411a to position and cooperate with the second bracket 300.
