[0048] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described below with the drawings in the embodiments of the present application. The following embodiments are used to explain the present application, but are not used to limit the scope of the present application.

[0049] In the embodiments of the present application, the terms "first", "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0050] In addition, in the embodiments of the present application, the orientation terms such as "upper", "lower", "left" and "right" are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0051] In the embodiments of the present application, unless otherwise specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0052] In the embodiments of the present application, the term "include", "contain" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "including a …" does not exclude the existence of other same elements in the process, method, article or device including the element.

[0053] In the embodiments of the present application, the word "exemplary" or "for example" is used to mean serving as an example or illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of "exemplary" or "for example" is intended to present concepts in a concrete manner.

[0054] The bushing in the suspension device in the related art is prone to be detached from the support arm, resulting in failure of the suspension device. The reason for this problem is that the suspension device can be used for connection and vibration isolation between the internal combustion engine and the subframe in the fuel vehicle, and the suspension device can also be used for connection and vibration isolation between the motor and the subframe in the electric drive vehicle. However, in the electric drive vehicle, the working mechanism of the electric drive is quite different from that of the fuel vehicle, and the motor generates a large torque fluctuation in the processes of sudden acceleration, sudden deceleration, gear shifting, and electric flameout, and receives a much larger transient impact than the internal combustion engine. Therefore, the existing suspension device cannot withstand the large torque fluctuation, and the suspension device is prone to cause the bushing to be detached from the support arm during use. In addition, the motor generates a large howling during operation, which affects the driving experience of the vehicle.

[0055] To solve the above problem, the embodiments of the present application provide a suspension device and a vehicle. The suspension device can connect the motor and the support arm through the first bushing by comprising the support arm and at least one first bushing arranged on the support arm. Since the motor and the support arm are both metal parts, the first bushing can avoid hard contact between the motor and the support arm, reduce the probability of damage between the motor and the support arm due to hard contact, and avoid noise generated by hard contact between the motor and the support arm. In addition, the first bushing can have a damping effect, so the first bushing can absorb the vibration generated by the motor during operation, reduce the probability of transmission of the vibration of the motor to the vehicle, and reduce the howling of the motor.

[0056] If the first bushing has a plurality of first bushings, the motor and the support arm are connected through the plurality of first bushings, which can further reduce the probability of transmission of the vibration generated by the motor during operation to the vehicle, and the plurality of first bushings can further reduce the howling of the motor and improve the use experience of the vehicle.

[0057] In addition, by arranging the limiting cover at at least one end in the axial extension direction of the first bushing and enabling the limiting cover to cover the mounting port for mounting the first bushing in the axial extension direction of the first bushing, when the first bushing is moved in the axial extension direction under the action of external force, the limiting cover can abut against the supporting arm near the mounting port to prevent the first bushing from being pulled out of the mounting port, thereby reducing the probability of the first bushing being pulled out of the mounting port of the supporting arm, improving the connection stability between the first bushing and the supporting arm, and improving the structural stability of the suspension device.

[0058] In addition, by arranging a plurality of first bushings to connect the motor to the supporting arm through the plurality of first bushings, the number of connection points between the motor and the supporting arm can be increased. When the motor applies the same external force to the suspension device, the suspension device can disperse the received force through the plurality of first bushings, and since the external force received by each first bushing is reduced, the probability of the first bushing being pulled out of the supporting arm due to the force of the motor can be reduced, and the structural stability of the suspension device can be improved.

[0059] The injection mold provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0060] With reference to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a suspension device, which can include a supporting arm 100, at least one first bushing 200, a second bushing 300, and a limiting cover 400.

[0061] The supporting arm 100 has at least one mounting port (not shown in the figure), and the mounting port can have one or more. The supporting arm 100 can be a metal piece to improve the structural strength of the supporting arm 100, for example, the supporting arm 100 can be an aluminum alloy structural piece. The mounting port can be used to mount the first bushing 200, and the number of mounting ports is the same as the number of first bushings 200.

[0062] The first bushing 200 can have one or more, and the first bushing 200 is arranged in the mounting port. The first bushing 200 is arranged one-to-one with the number of mounting ports, the first bushing 200 is arranged in intervals with the second bushing 300, and the first bushing 200 is used to be connected to the motor. The first bushing 200 can be pressed into the mounting port by interference fit to improve the connection stability between the first bushing 200 and the supporting arm 100.

[0063] When there are a plurality of first bushings 200, the plurality of first bushings 200 can be arranged in intervals on the supporting arm 100 to disperse the force of the motor received by each first bushing 200.

[0064] The application provides a suspension device, which can connect a motor and a support arm 100 through a first bushing 200 arranged on the support arm 100. Since the motor and the support arm 100 are both metal parts, the first bushing 200 can avoid hard contact between the motor and the support arm 100, reduce the probability of damage between the motor and the support arm 100 due to hard contact, and avoid noise caused by hard contact between the motor and the support arm 100. In addition, the first bushing 200 can have a damping effect, so that the first bushing 200 can absorb the vibration generated when the motor works, reduce the probability of transmission of the vibration of the motor to the whole vehicle, and reduce the howling of the motor.

[0065] If the first bushing 200 has a plurality of first bushings 200, the motor and the support arm 100 are connected through the plurality of first bushings 200, which can further reduce the probability of transmission of the vibration generated when the motor works to the whole vehicle, and the plurality of first bushings 200 can further reduce the howling of the motor and improve the use experience of the vehicle.

[0066] In addition, the plurality of first bushings 200 are arranged to connect the motor and the support arm 100 through the plurality of first bushings 200, which can increase the connection points between the motor and the support arm 100. When the motor applies the same external force to the suspension device, the suspension device can disperse the received force through the plurality of first bushings 200. Since the external force received by each first bushing 200 is reduced, the probability of the first bushing 200 being detached from the support arm 100 due to the force of the motor is reduced, and the structural stability of the suspension device is improved.

[0067] Referring to Figure 1 , the second bushing 300 is arranged on the support arm 100, and the second bushing 300 is used to be connected with a subframe. The extending direction of the axis (such as the axis P in Figure 1 ) of the first bushing 200 is perpendicular to the extending direction of the axis (such as the axis M in Figure 1 ) of the second bushing 300.

[0068] The subframe can have a mounting hole, so that the second bushing 300 on the suspension device is pressed into the mounting hole on the subframe in a interference fit mode, so as to realize the connection of the support arm 100 and the subframe through the interference fit of the second bushing 300 and the mounting hole. In this way, the connection stability between the second bushing 300 and the subframe can be improved.

[0069] In this way, the suspension device connects the support arm 100 and the subframe by using the second bushing 300. Since the subframe and the support arm 100 are both metal parts, the support arm 100 and the subframe are connected through the second bushing 300, which can avoid direct hard contact between the support arm 100 and the subframe, reduce the probability of collision or friction damage of the support arm 100 or the subframe, and reduce noise and other problems caused by hard contact, thereby improving the service life of the suspension device and the subframe and the noise reduction effect. In addition, the second bushing 300 can absorb the vibration caused by the relative movement between the support arm 100 and the subframe, thereby reducing the transmission of vibration between the support arm 100 and the subframe and improving the damping effect of the suspension device.

[0070] With reference to Figures 1 to 4 The limiting cover 400 is arranged at one end of the first bushing 200 in the axial extension direction, and covers the mounting port. In this way, when the first bushing 200 moves relative to the support arm 100 in the axial extension direction, the limiting cover 400 can abut against the surface of the support arm 100 near the mounting port. For example, taking the orientation of the suspension device in Figure 1 The limiting cover 400 can be arranged above the first bushing 200, and when the first bushing 200 moves downward relative to the support arm 100, the limiting cover 400 above the first bushing 200 can abut against the surface of the support arm 100 near the mounting port, thereby preventing the first bushing 200 from moving further downward and avoiding the first bushing 200 from being pulled out of the support arm 100.

[0071] By arranging the limiting cover 400 at at least one end of the first bushing 200 in the axial extension direction and allowing the limiting cover 400 to cover the mounting port for mounting the first bushing 200 in the axial extension direction, when the first bushing 200 is subjected to external force and moves in the axial extension direction, the limiting cover 400 can abut against the support arm 100 near the mounting port to limit the further movement of the first bushing 200 in the axial direction, thereby avoiding the first bushing 200 from being pulled out of the mounting port, improving the connection stability between the first bushing 200 and the support arm 100, and improving the structural stability of the suspension device.

[0072] In some embodiments, the limiting cover 400 can have two, one limiting cover 400 is arranged at each end of the first bushing 200 in the axial extension direction. In this way, the displacement of the first bushing 200 can be limited by the limiting cover 400 when the first bushing 200 moves up and down relative to the support arm 100 in the axial direction, thereby further avoiding the first bushing 200 from being pulled out of the support arm 100.

[0073] In some embodiments of the present application, with reference to Figures 1 to 4The first bushing 200 can include an inner tube 210, a damping body 220, and an outer tube 230. The inner tube 210, the damping body 220, and the outer tube 230 are all arranged in the mounting hole.

[0074] The inner tube 210 is used to be connected with the limiting cover 400. The inner tube 210 can be a metal piece. The inner tube 210 and the limiting cover 400 can be connected by riveting. In this way, the connection stability between the inner tube 210 and the limiting cover 400 can be increased.

[0075] In some embodiments, the inner tube 210 can be used to be connected with the motor, so as to realize the connection between the motor and the suspension device. For example, the inner tube 210 can be connected with the motor by bolts. In this way, the detachable connection between the motor and the suspension device can be realized.

[0076] In some embodiments, the limiting cover 400 has a through hole in communication with the inner tube 210, so as to facilitate the bolts to pass through the inner tube 210 and the limiting cover 400 and to be detachably connected with the motor.

[0077] The damping body 220 is arranged outside the inner tube 210. The damping body 220 can be made of rubber. The damping body 220 can be made of rubber by using a vulcanization process. In this way, the damping performance of the damping body 220 can be ensured, and the corrosion resistance of the rubber can be improved.

[0078] The outer tube 230 is arranged outside the damping body 220. The outer tube 230 is arranged in the mounting hole. The outer wall of the outer tube 230 abuts against the inner wall of the mounting hole. In some embodiments, the outer tube 230 can be a metal piece, so as to increase the structural strength of the first bushing 200.

[0079] In some embodiments, the inner tube 210, the outer tube 230, and the damping body 220 can be an integrated structure. For example, the inner tube 210, the outer tube 230, and the damping body 220 can be made by an integrated injection molding process.

[0080] In some embodiments of the present application, referring to Figures 1 to 4 The limiting cover 400 can be a flat plate structure. The limiting plate is connected with the inner tube 210 by riveting.

[0081] In some embodiments of the present application, referring to Figures 1 to 4 The limiting cover 400 has a convex portion 410. The convex portion 410 protrudes from the side of the limiting cover 400 facing the first bushing 200 to the side of the limiting cover 400 facing away from the first bushing 200.

[0082] In this way, by arranging the protrusion 410 on the limiting cover 400, compared with the limiting cover 400 of the flat plate structure, since the protrusion 410 can increase the cross-sectional height of the cover plate in the thickness direction, the moment of inertia can be improved, and the limiting cover 400 can have higher rigidity under bending load. In addition, by arranging the protrusion 410, the height of the limiting cover 400 in the thickness direction can be increased, and the deformation resistance of the limiting cover 400 can be further improved.

[0083] In some embodiments, the protrusion 410 on the limiting cover 400 can be a stamping protrusion, for example, the protrusion 410 can be obtained by stamping the limiting cover 400. The limiting cover 400 can have at least one protrusion 410, for example, the limiting cover 400 can have one protrusion 410 or a plurality of protrusions 410.

[0084] In some embodiments, the protrusion 410 on the limiting cover 400 can also protrude towards the first bushing 200.

[0085] In some embodiments of the present application, with reference to Figures 1 to 4 The first bushing 200 can further include a buffer pad 240. The buffer pad 240 is arranged between the limiting cover 400 and the support arm 100, and the buffer pad 240 is used to indirectly contact the limiting cover 400 and the support arm 100. The buffer pad 240 can be a circular ring and is connected to the shock-absorbing body 220 of the first bushing 200.

[0086] When the first bushing 200 moves along the axial extension direction and the limiting cover 400 abuts against the surface of the support arm 100, direct contact occurs between the limiting cover 400 and the surface of the support arm 100. Since the support arm 100 and the limiting cover 400 are both metal parts, direct contact between the support arm 100 and the limiting cover 400 can easily damage the support arm 100 and the limiting cover 400, and can also generate a large noise and vibration.

[0087] In this way, by arranging the buffer pad 240 between the limiting cover 400 and the support arm 100, direct contact between the limiting cover 400 and the surface of the support arm 100 can be avoided, and the limiting cover 400 abuts against the surface of the support arm 100 through the buffer pad 240. The buffer pad 240 can absorb the impact force between the limiting cover 400 and the support arm 100, and can reduce the probability of damage of the limiting cover 400 and the support arm 100 due to direct contact.

[0088] In some embodiments, the buffer pad 240 can be a rubber pad. Compared with the direct contact between the limiting cap 400 and the support arm 100, the rubber pad has a deformation capacity and can absorb impact force by deformation. The contact between the limiting cap 400 and the rubber pad can reduce the wear and damage of the limiting cap 400, and the contact between the support arm 100 and the rubber pad can also reduce the wear and damage of the support arm 100, thereby improving the service life of the limiting cap 400 and the support arm 100 and improving the service life of the suspension device.

[0089] In some embodiments, if the first bushing 200 is provided with one limiting cap 400 at each end in the axial extension direction, the buffer pad 240 can also have two, and each buffer pad 240 can be arranged between the limiting cap 400 and the support arm 100.

[0090] In some embodiments, if the first bushing 200 can include a damping body 220 and the first bushing 200 is provided with a buffer pad 240 at each end, one of the buffer pads 240 can be in an integral structure with the damping body 220. For example, when the buffer pad 240 and the damping body 220 are both rubber parts, the buffer pad 240 and the damping body 220 can be prepared by injection molding.

[0091] In some embodiments of the present application, referring to Figures 1 to 4 The buffer pad 240 can include a first protrusion 241 arranged on the side of the buffer pad 240 facing the limiting cap 400.

[0092] In this way, by arranging the first protrusion 241 on the side of the buffer pad 240 facing the limiting cap 400, the thickness of the buffer pad 240 can be increased, the compression deformation space of the buffer pad 240 in the thickness direction can be increased, and the buffering effect of the buffer pad 240 can be improved on the basis of saving the material cost of the buffer pad 240.

[0093] In some embodiments, the first protrusion 241 can have a plurality of first protrusions 241 arranged at intervals in the circumferential direction of the buffer pad 240.

[0094] In some embodiments of the present application, referring to Figures 1 to 4 The buffer pad 240 can further include a second protrusion 242 arranged on the side of the buffer pad 240 facing the support arm 100.

[0095] In this way, by arranging the second protrusion 242 on the side of the buffer pad 240 facing the support arm 100, the thickness of the buffer pad 240 can be increased, the compression deformation space of the buffer pad 240 in the thickness direction can be increased, and the buffering effect of the buffer pad 240 can be improved on the basis of saving the material cost of the buffer pad 240.

[0096] In some embodiments, the second protrusion 242 can be provided in plurality, and the plurality of second protrusions 242 can be arranged at intervals along the circumference of the cushion pad 240.

[0097] In some embodiments, the cushion pad 240 can be provided with the first protrusion 241 on the surface facing the limiting cover 400, in addition to being provided with the second protrusion 242 on the surface facing the support arm 100, so as to further improve the cushioning effect of the cushion pad 240.

[0098] In some embodiments of the present application, referring to Figures 1 to 4 , the first bushing 200 can be provided in plurality, for example, the first bushing 200 can be provided in two, three, four or even more.

[0099] In an example, the plurality of first bushings 200 can include four, of which two first bushings 200 are symmetrically arranged with the other two first bushings 200 about a first axis (as shown by the symmetry axis M in Figure 1 ).

[0100] It should be noted that the first axis is not a physical structure, and the first axis is used to define the positional relationship between the four first bushings 200.

[0101] By providing the plurality of first bushings 200, the vibration isolation effect between the motor and the support arm 100 can be improved, and thus the vibration isolation effect of the suspension device can be improved. In addition, by providing the plurality of first bushings 200, the vibration generated by the motor can be dispersed to each first bushing 200, so as to reduce the load of a single first bushing 200, reduce the probability of damage to the first bushing 200, and improve the service life of the suspension device.

[0102] The layout of the two-by-two symmetrically arranged first bushings 200 can also keep the motor balanced during operation, and reduce the shaking and noise of the motor caused by imbalance.

[0103] In addition, by symmetrically arranging the two first bushings 200 with the other two first bushings 200 about the first axis, the uniformity of the distribution of the first bushings 200 on the support arm 100 can be improved, so that the force transmitted by the motor to the support arm 100 can be uniformly distributed to each first bushing 200, avoiding uneven stress on each first bushing 200.

[0104] In some embodiments of the present application, referring to Figures 1 to 4 , the axis of the second bushing 300 is parallel to the first axis. When there are four first bushings 200, and the other two first bushings 200 are symmetrically arranged with the other two first bushings 200 about the first axis, the axis of the second bushing 300 can be parallel to the first axis.

[0105] In this way, the force of the motor acting on the four first bushings 200 can be evenly transmitted to the second bushing 300 through the support arm 100 and then evenly transmitted to the subframe through the second bushing 300, which helps to reduce the local stress concentration on the suspension device, thereby reducing the risk of material fatigue and damage.

[0106] The embodiments of the present application also provide a vehicle, referring to Figures 1 to 4 , the vehicle can include a motor, a subframe and the suspension device as above. The suspension device can include a support arm 100, a first bushing 200, a limiting cover 400 and a second bushing 300.
