Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an engine suspension pad and a vehicle. Background Technology

[0002] Engine mounts are crucial components of a vehicle's powertrain, primarily used to support the engine and reduce the transmission of its vibrations to the vehicle body, thereby improving vehicle comfort and the lifespan of other parts. Engine mounts typically incorporate rubber to absorb and isolate vibrations generated by the engine.

[0003] In the existing technology, when encountering bumpy roads, the engine vibrates significantly, which can easily cause deformation of the upper and lower skeletons of the suspension pads, leading to stress concentration and tearing of the rubber material. This can affect the vibration isolation effect of the engine suspension. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an engine mount pad with a more stable structure and more reliable vibration reduction.

The second limiting part further includes an inclined portion, one end of which is connected to the end of the second sub-limiting part away from the second connector in a second direction. The other end of which is inclined relative to the second sub-limiting part towards the first connector in a first direction. The outer side of the arc portion and the inner side of the inclined portion selectively limit and cooperate.

[0012] According to some embodiments of the present invention, the second limiting part, the first limiting part, the elastic member and the third limiting part are arranged sequentially at intervals in a first direction.

[0013] According to some embodiments of the present invention, the engine suspension pad further includes a buffer member, which is connected to the elastic member. The buffer member includes a first buffer member and a second buffer member. The first buffer member is at least partially disposed on the side of the first connector facing the second connector, and the second buffer member is at least partially disposed on the side of the second connector facing the first connector.

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figure 1 The engine mount pad 100 according to an embodiment of the present invention can be applied to a vehicle.

[0022] Combination Figure 1 As shown, the engine suspension pad 100 according to an embodiment of the present utility model may mainly include: a first connector 10, a second connector 20 and an elastic member 30. The first connector 10 is connected to the engine bracket, so that vibration can be transmitted between the engine bracket and the first connector 10. The first connector 10 extends in a first direction, so that the size of the first connector 10 in the first direction can be increased to increase the area of ​​the first connector 10.

[0023] Furthermore, the first connector 10 is provided with a first limiting part 11 at at least one end in the first direction, so that the first connector 10 can provide a setting position for the first limiting part 11 to ensure the reliability of the setting of the first limiting part 11 on the first connector 10.

[0024] Furthermore, the second connector 20 is connected to the frame, which allows vibration to be transmitted between the frame and the second connector 20. The second connector 20 extends in the first direction, which increases the size of the second connector 20 in the first direction and thus increases the area of ​​the second connector 20.

[0025] Furthermore, the second connector 20 is provided with a second limiting part 21 at at least one end in the first direction, so that the second connector 20 can provide a setting position for the second limiting part 21 to ensure the reliability of the setting of the second limiting part 21 on the second connector 20.

[0026] In an embodiment of this utility model, the second connector 20 and the first connector 10 are arranged opposite to each other in the second direction. This allows an elastic member 30 to be provided between the second connector 20 and the first connector 10, with both ends of the elastic member 30 connected to the first connector 10 and the second connector 20, respectively. This not only allows vibration to be transmitted between the first connector 10 and the second connector 20, but also allows the elastic member 30 to absorb vibration and noise, thereby reducing the transmission of vibration from the engine to the vehicle frame.

[0027] Furthermore, the second limiting part 21 selectively limits and engages with the first limiting part 11 in the first direction at least partially, and selectively limits and engages with the first limiting part 11 in the second direction at least partially, wherein the first direction and the second direction are perpendicular to each other. With this arrangement, when the vehicle is traveling on a bumpy road surface, the displacement of the first connecting member 10 relative to the second connecting member 20 in the first and second directions can be reduced, thereby preventing the engine mount pad 100 from deforming due to impact after the first connecting member 10 falls relative to the second connecting member 20. This can solve the problem of structural tearing caused by stress concentration on the first connecting member 10 and the second connecting member 20, thereby improving the structural stability and vibration reduction reliability of the engine mount pad 100.

[0028] Combination Figure 1 As shown, the first limiting part 11 includes a first sub-limiting part 111, which bends toward the second connecting member 20 relative to the first connecting member 10. The second limiting part 21 includes a second sub-limiting part 211, which bends toward the first connecting member 10 relative to the second connecting member 20. Both the first sub-limiting part 111 and the second sub-limiting part 211 extend along a second direction. The first sub-limiting part 111 and the second sub-limiting part 211 are spaced apart in a first direction and selectively limit and cooperate with each other.

[0029] Specifically, one end of the first sub-limiting portion 111 is connected to one end of the first connecting member 10 in the first direction, and the other end is bent relative to the first connecting member 10 toward the second connecting member 20. This allows the first sub-limiting portion 111 to extend along the second direction, thereby increasing the size and area of ​​the first sub-limiting portion 111 in the second direction. One end of the second sub-limiting portion 211 is connected to one end of the second connecting member 20 in the first direction, and the other end is bent relative to the second connecting member 20 toward the first connecting member 10. This allows the second sub-limiting portion 211 to extend along the second direction, thereby increasing the size and area of ​​the second sub-limiting portion 211 in the second direction.

[0030] Furthermore, the second sub-limiting part 211 is located on the second connector 20 at one end of the second connector 20 adjacent to the first sub-limiting part 111 in the first direction, and the second sub-limiting part 211 and the first sub-limiting part 111 are spaced apart in the first direction. This allows the second sub-limiting part 211 and the first sub-limiting part 111 to be arranged adjacent to each other in the first direction, so that the second connector 20 can selectively limit the first connector 10 in the first direction through the selective limiting cooperation of the second sub-limiting part 211 and the first sub-limiting part 111.

[0031] This configuration reduces the displacement of the first connector 10 relative to the second connector 20 in the first direction. This reduces the impact force generated when the first connector 10 returns and collides with the second connector 20, thus reducing the possibility of deformation of the first connector 10 and the second connector 20. This solves the problem of structural tearing caused by stress concentration on the first connector 10 and the second connector 20, thereby improving the structural reliability of the engine mount pad 100 and ensuring the vibration reduction reliability of the engine mount pad 100.

[0032] Combination Figure 1 As shown, the first limiting part 11 also includes an arc part 112, which is connected between the first connector 10 and the first sub-limiting part 111. The second limiting part 21 also includes an inclined part 212, one end of which is connected to the end of the second sub-limiting part 211 that is away from the second connector 20 in the second direction. The other end of the inclined part 212 is inclined relative to the second sub-limiting part 211 towards the first connector 10 in the first direction. The outer side of the arc part 112 and the inner side of the inclined part 212 selectively limit and cooperate with each other.

[0033] This arrangement allows the inclined portion 212 and the arc portion 112 to be at least partially spaced apart in the second direction. In this way, during engine operation, the inclined portion 212 and the arc portion 112 can selectively limit the engagement of the second connector 20 with respect to the first connector 10 in the second direction.

[0034] This configuration reduces the displacement of the first connector 10 relative to the second connector 20 in the second direction. This reduces the impact force generated when the first connector 10 returns and collides with the second connector 20, thus reducing the possibility of deformation of the first connector 10 and the second connector 20. This solves the problem of structural tearing caused by stress concentration on the first connector 10 and the second connector 20, thereby improving the structural reliability of the engine mount pad 100 and ensuring the vibration reduction reliability of the engine mount pad 100.

[0035] Combination Figure 1 As shown, a third limiting part 22 is provided at one end of the second connector 20 away from the second limiting part 21 in the first direction. The third limiting part 22 extends toward the first connector 10 in the second direction. The third limiting part 22 and the first limiting part 11 are spaced apart and selectively limit each other in the first direction.

[0036] Specifically, the third limiting part 22 is disposed at the end of the second connector 20 away from the second limiting part 21 in the first direction. Both ends of the first connector 10 in the first direction are provided with first limiting parts 11. The third limiting part 22 and the first limiting part 11 at the adjacent end of the first connector 10 selectively limit and cooperate in the first direction, which can prevent the first connector 10 from having excessive displacement relative to the second connector 20 in the first direction toward the side away from the second limiting part 21, thereby enhancing the reliability of the mutual limiting between the second connector 20 and the first connector 10 in the first direction.

[0037] Combination Figure 1 As shown, the length of the second connector 20 in the first direction is set to L1, and the total length of the first connector 10 and the first limiting part 11 in the first direction is set to L2. L1 and L2 satisfy the relationship: L1 > L2.

[0038] Specifically, in the embodiments of this utility model, the length of the second connector 20 in the first direction is greater than the total length of the first connector 10 and the first limiting part 11 in the first direction. This not only ensures that the first limiting part 11 adjacent to the second limiting part 21 at both ends of the first connector 10 in the first direction is spaced apart from the second limiting part 21 in the first direction, but also ensures that the first limiting part 11 adjacent to the third limiting part 22 at both ends of the first connector 10 in the first direction is spaced apart from the third limiting part 22 in the first direction.

[0039] Combination Figure 1As shown, the second limiting part 21, the first limiting part 11, the elastic member 30, and the third limiting part 22 are arranged sequentially at intervals in the first direction. This arrangement allows the first connecting member 10 to have a certain movable space relative to the second connecting member 20 in the first direction. This allows the elastic member 30 between the first connecting member 10 and the second connecting member 20 to have a certain deformable deformation in the first direction. Thus, the deformation capability of the elastic member 30 can absorb at least part of the vibration between the first connecting member 10 and the second connecting member 20, thereby achieving the vibration reduction effect of the engine suspension pad 100.

[0040] Combination Figure 1 As shown, the engine suspension pad 100 in this utility model also includes a buffer 40, which is connected to the elastic member 30. The buffer 40 includes a first buffer 41 and a second buffer 42. The first buffer 41 is at least partially disposed on the side of the first connector 10 facing the second connector 20, and the second buffer 42 is at least partially disposed on the side of the second connector 20 facing the first connector 10.

[0041] Specifically, both the buffer 40 and the elastic element 30 have a certain function of absorbing and isolating vibration. A first buffer 41 is provided on the side of the first connector 10 facing the second connector 20, and a second buffer 42 is provided on the side of the second connector 20 facing the first connector 10. This can buffer the collision caused by the relative movement and fall of the first connector 10 and the second connector 20. This can effectively prevent the deformation of the first connector 10 and the second connector 20 caused by the transmission of vibration in the engine mount pad 100 when the vehicle is driving on bumpy roads. It can solve the problem of structural tearing caused by stress concentration on the first connector 10 and the second connector 20, thereby improving the structural reliability of the first connector 10 and the second connector 20, and further improving the structural reliability and vibration reduction reliability of the engine mount pad 100.

[0042] Combination Figure 1 As shown, the buffer 40 also includes a third buffer 43 and a fourth buffer 44. The third buffer 43 is at least partially disposed on the side of the second limiting portion 21 facing the first limiting portion 11, and the fourth buffer 44 is at least partially disposed on the side of the first limiting portion 11 facing the second limiting portion 21 and the third limiting portion 22.

[0043] Specifically, a third buffer 43 is provided on the side of the second limiting part 21 facing the first limiting part 11, and a fourth buffer 44 is provided on the side of the first limiting part 11 facing the second limiting part 21. This can buffer the collision between the first limiting part 11 and the second limiting part 21 caused by relative movement and falling. This can effectively prevent the deformation of the first limiting part 11 and the second limiting part 21 caused by the transmission of vibration in the engine suspension pad 100 when the vehicle is traveling on bumpy roads. It can solve the problem of structural tearing caused by stress concentration on the first connecting member 10 and the second connecting member 20, thereby improving the structural reliability of the first limiting part 11 and the second limiting part 21, and further improving the structural reliability and vibration reduction reliability of the engine suspension pad 100.

[0044] Combination Figure 1 As shown, the buffer 40 also includes a fifth buffer 45, which is disposed at the end of the inclined portion 212 that is away from the second sub-limiting portion 211 in the second direction. With this configuration, when the first sub-limiting portion 111 and the second sub-limiting portion 211 are displaced relative to each other in the second direction, the fifth buffer 45 can buffer the collision between the end of the second sub-limiting portion 211 that is away from the second connecting member 20 in the second direction and the engine bracket. This can effectively prevent the deformation of the end of the second sub-limiting portion 211 that is away from the second connecting member 20 in the second direction due to the transmission of vibration in the engine suspension pad 100 when the vehicle is traveling on a bumpy road. This can improve the structural reliability of the second sub-limiting portion 211 and the engine bracket, and further improve the structural reliability and vibration reduction reliability of the engine suspension pad 100.

[0045] According to an embodiment of this utility model, the engine suspension pad 100 can be applied in a vehicle. By setting the first limiting part 11 on the first connecting member 10 and the second limiting part 21 on the second connecting member 20 to selectively limit and cooperate in both the first and second directions, the displacement of the first connecting member 10 relative to the second connecting member 20 in the first and second directions can be reduced when the vehicle is traveling on a bumpy road. This can prevent the engine suspension pad 100 from deforming due to impact after the first connecting member 10 falls back relative to the second connecting member 20. It can solve the problem of structural tearing caused by stress concentration on the first connecting member 10 and the second connecting member 20, thereby improving the structural stability and vibration reduction reliability of the engine suspension pad 100.

[0046] Furthermore, by providing an elastic element 30 and a buffer element 40 between the first connector 10 and the second connector 20, the vibration isolation capability of the engine mount pad 100 is improved, and the deformation of the structure in the engine mount pad 100 due to stress concentration can be effectively prevented. This arrangement can improve the reliability of the engine mount pad 100.
