The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0035] In order to describe the present invention in detail, the vehicle engine suspension mounting bracket of the present invention is specifically described below:

[0036] Please combine Figures 1 to 3As shown, the utility model provides a vehicle engine suspension mounting support, including: a base 1, a cover 2, a first vibration reduction assembly and a second vibration reduction assembly. The base 1 is mounted on a suspension bracket 3, and the suspension bracket 3 is used to connect with the vehicle frame; the cover 2 is connected to the top of the base 1 and can move in the vertical direction and the horizontal direction, and the cover 2 is used to connect with the engine body; the first vibration reduction assembly includes an annular vibration reduction body 11 arranged on the base 1 and an annular support body 21 arranged on the inner side of the cover 2, and the annular support body 21 abuts against the annular vibration reduction body 11 to dissipate the vibration energy in the vertical direction; the second vibration reduction assembly includes a central axis 4 arranged on the base 1 and an energy dissipation mechanism 5 matched with the central axis 4, and the central axis 4 can move in the vertical direction under the driving action of the cover 2, and the energy dissipation mechanism 5 is horizontally arranged in multiple groups along the circumference of the central axis 4 to dissipate the vibration energy in the vertical direction and the horizontal direction.

[0037] Specifically, the base 1 is fixedly mounted on the suspension bracket 3, and the suspension bracket 3 is connected to the frame by bolts; the cover body 2 is provided with a stud 24 for connecting the cover body 2 with the engine body, so as to support the engine body through the cover body 2. When the engine body vibrates, the vehicle engine suspension mounting bracket will dissipate the energy of the vibration to isolate the transmission of the vibration to the vehicle body. Among them, the first vibration reduction component forms a primary vibration reduction, and the first vibration reduction component and the second vibration reduction component together form a secondary vibration reduction. When the vibration generated by the engine body is small, the first vibration reduction component works to dissipate the vibration energy in the vertical direction; when the vibration generated by the engine body is large, the first vibration reduction component and the second vibration reduction component work together to dissipate the vibration energy in the vertical direction. In addition, the second vibration reduction component can also dissipate the vibration energy in the horizontal direction.

[0038] The first vibration damping assembly includes an annular vibration damper 11 and an annular support 21. Both the annular vibration damper 11 and the annular support 21 are annularly arranged. The annular vibration damper 11 is arranged on the base 1, and can support the cover 2 in the initial state, and can be squeezed by the cover 2 when the cover 2 has a vertical displacement, so as to dissipate the vertical vibration energy. Correspondingly, an annular support 21 is arranged at the inner side of the cover 2 corresponding to the annular vibration damper 11, and the bottom of the annular support 21 is in contact with the annular vibration damper 11, so as to compress the annular vibration damper 11 when the cover 2 is subjected to a vertical load, thereby playing a role in dissipating the vibration energy in the vertical direction.

[0039] The second vibration reduction assembly includes a central axis 4 and an energy dissipation mechanism 5. The central axis 4 is movably located in the middle of the base 1 and can move in the vertical direction. The energy dissipation mechanism 5 is evenly distributed in multiple groups along the circumference of the central axis 4. In this embodiment, four groups can be arranged to dissipate vertical and horizontal vibration energy.

[0040] In some embodiments, the annular vibration damper 11 includes a spring group 111 and a first elastic ring 112, wherein the spring group 111 is located inside the first elastic ring 112; the annular support body 21 includes a first support portion 211 and a second support portion 212 extending in a direction away from the cover body 2, wherein the first support portion 211 is located inside the second support portion 212, and the first support portion 211 abuts against the spring group 111, and the second support portion 212 abuts against the first elastic ring 112. Specifically, the spring group 111 is arranged in an annular manner around the central axis 4, and the first elastic ring 112 surrounds the periphery of the spring group 111. This double-layer structure design enables the annular vibration damper 11 to more effectively absorb and disperse the vibration energy in the vertical direction. The spring group 111 bears the load acting in the axial direction, stores energy by being compressed and deformed, and gradually releases it during the vibration process, thereby achieving a vibration reduction effect; at the same time, the first elastic ring 112 serves as a peripheral protective layer, further enhancing the stability of the overall structure and the ability to absorb vibration energy. The first support portion 211 and the second support portion 212 on the cover body 2 are also arranged in a ring shape. The first support portion 211 corresponds to the spring group 111 and abuts against the spring group 111, ensuring that the engine body transmits vibration to the spring group 111 through the cover body 2, and the spring group 111 can respond quickly and play a vibration reduction role when subjected to vibration pressure; the second support portion 212 corresponds to the first elastic ring 112 and abuts against the first elastic ring 112, which further enhances the vibration dissipation performance.

[0041] It can be understood that the top of the base 1 is provided with an annular receiving groove 12, and the annular vibration damper 11 is located in the annular receiving groove 12; the annular receiving groove 12 includes a first annular groove 121 and a second annular groove 122 which are coaxially arranged, the first annular groove 121 is located inside the second annular groove 122, the spring group 111 is located in the first annular groove 121, and the first elastic ring 112 is located in the second annular groove 122. In this way, the first annular groove 121 can play a role of installation limit for the spring group 111, and the second annular groove 122 can play a role of installation limit for the first elastic ring 112.

[0042] Preferably, the spring group 111 is coaxially arranged with the first elastic ring 112, and the first support portion 211 is coaxially arranged with the second support portion 212; the spring group 111 includes a plurality of coaxial disc springs stacked back to back. Specifically, the spring group 111 and the first elastic ring 112 have the same center line, and correspondingly, the first support portion 211 and the second support portion 212 have the same center line. This coaxially arranged structure ensures that the force line of the spring group 111 is evenly distributed along the center line when it is compressed or released, avoiding vibration or instability caused by eccentric torque; the coaxial configuration also helps to reduce the additional stress caused by non-axial force, thereby extending the service life of the spring group 111. The spring group 111 uses a plurality of coaxial disc springs stacked back to back. The back-to-back stacking allows each disc spring to fully exert its elastic potential energy, and the mutual forces offset part of the vibration, thereby improving the efficiency of energy conversion. In addition, the first elastic ring 112 can be made of rubber material or other elastic compressible materials.

[0043] In some embodiments, the middle of the base 1 is provided with a central receiving groove 13 with an upper opening, the central shaft 4 is located in the central receiving groove 13, and the middle of the central shaft 4 is provided with a through hole 41 along the axial direction; the inner side of the cover 2 is provided with a protrusion 22 extending in a direction away from the cover 2, and the front end of the protrusion 22 extends into the through hole 41. Specifically, the through hole 41 is penetrated along the axial direction of the central shaft 4, and the protrusion 22 is provided at the middle of the inner side of the cover 2 corresponding to the central shaft 4, and the protrusion 22 extends into the through hole 41, so as to push the central shaft 4 to move synchronously when it abuts against the through hole 41 of the central shaft 4.

[0044] In the above embodiment, the front end of the protrusion 22 has a first step surface 221, and the through hole 41 is provided with a second step surface 411 that matches the first step surface 221. Specifically, the protrusion 22 has an initial position and a working position. In the initial position, there is a first vertical gap 61 between the first step surface 221 of the protrusion 22 and the second step surface 411 of the through hole 41; in the working position, that is, the cover body 2 is vibrated and pressed down, so that the first step surface 221 of the protrusion 22 is in contact with the second step surface 411 of the through hole 41, and can continue to compress the central axis 4 to produce displacement in the vertical direction. In this way, when the load is small, the first vibration reduction component is relied on to reduce vibration and dissipate the vertical vibration energy.

[0045] In the above embodiment, a limiting shaft 14 is arranged in the central receiving groove 13 of the base 1 along the vertical direction, the central shaft 4 is slidably sleeved on the limiting shaft 14 through the through hole 41, and a supporting elastic member 15 is connected between the limiting shaft 14 and the protruding portion 22; a second elastic ring 16 is sleeved on the outer side of the limiting shaft 14, and the two ends of the second elastic ring 16 are respectively in contact with the bottom of the central receiving groove 13 and the central shaft 4. Specifically, the limiting shaft 14 is inserted into the through hole 41 of the central shaft 4 from bottom to top, so that the limiting shaft 14 can guide the vertical displacement of the central shaft 4 and limit the displacement of the central shaft 4 in the horizontal direction. Through the setting of the limiting shaft 14, the central shaft 4 can only move in the vertical direction, but will not move in the horizontal direction. In this embodiment, the annular support body 21 and the protrusion 22 are integrally formed with the cover body 2, and the limiting shaft 14 is integrally formed with the base 1. The movement of the central axis 4 is restricted by the limiting shaft 14, so that the central axis 4 can produce vertical displacement under the pressure of the protrusion 22, but the central axis 4 cannot produce horizontal displacement.

[0046] Furthermore, a supporting elastic member 15 is connected between the limiting shaft 14 and the protruding portion 22. The supporting elastic member 15 is located in the through hole 41 of the central shaft 4. The bottom end of the supporting elastic member 15 abuts against the top end of the limiting shaft 14, and the top end of the supporting elastic member 15 abuts against the protruding portion 22 of the cover body 2. This structure is conducive to the supporting elastic member 15 maintaining the first vertical gap 61 between the protruding portion 22 and the central shaft 4 in the natural state; when the cover body 2 is in a compressed state, the protruding portion 22 compresses the central shaft 4 to move, and can also dissipate the vertical vibration energy.

[0047] In addition, a second elastic ring 16 is sleeved on the outer side of the limiting shaft 14, and the two ends of the second elastic ring 16 are respectively in contact with the bottom of the central receiving groove 13 and the central shaft 4. Specifically, the second elastic ring 16 is sleeved on the limiting shaft 14 and is located at the bottom of the central receiving groove 13 to support the central shaft 4. For the vibration energy in the vertical direction, the second elastic ring 16 can work together with the second vibration reduction assembly to further improve the dissipation of the vertical vibration energy. The second elastic ring 16 can be made of rubber material or other elastic and compressible material.

[0048] In the initial state, the annular vibration damping body 11 of the first vibration damping assembly forms a floating support for the cover body 2. When subjected to a load, the first vibration damping assembly and the second vibration damping assembly dissipate the vibration energy in the vertical direction. Specifically, the first vibration damping assembly forms a first-level vibration damping, that is, when the load is small, the first vibration damping assembly works. When the load is large, when the vertical displacement of the cover body 2 is greater than the first vertical gap 61 between the protrusion 22 and the central axis 4, the protrusion 22 contacts the central axis 4 and drives the central axis 4 to move. At this time, the first vibration damping assembly and the second vibration damping assembly work together to dissipate the vibration energy in the vertical direction.

[0049] In some embodiments, the base 1 is horizontally provided with a plurality of horizontal receiving holes 17 along the circumferential direction of the central axis 4, the horizontal receiving holes 17 are in communication with the central receiving groove 13, and the energy dissipation mechanism 5 is located in the horizontal receiving holes 17. Specifically, in this embodiment, four horizontal receiving holes 17 are provided to respectively accommodate four groups of energy dissipation mechanisms 5, and each group of energy dissipation mechanisms 5 is arranged along the horizontal receiving holes 17 corresponding thereto, for dissipating the vertical vibration energy transmitted from the central axis 4.

[0050] When the load is too large, due to the presence of the second vibration damping assembly, the vibration energy in the vertical direction can be dissipated through the energy dissipation mechanism 5 arranged in the horizontal direction, thereby changing the limitation of the vibration energy direction, which is significantly different from the method of dissipating the vertical vibration energy by vertically arranging the energy dissipation mechanism 5 in the prior art. Moreover, by arranging the dissipation mechanism that can dissipate the vertical vibration energy in the horizontal direction, the overall layout of the vibration damping device is more reasonable, and the space in the horizontal direction can be fully utilized, and at the same time, the volume or size of the vibration damping device in the vertical direction can be reduced, so that the structure of the vibration damping device is more compact and can be better adapted to the cramped space for engine installation. In addition, the energy dissipation mechanism 5 can be arranged in multiple numbers along the circumference of the base 1 in the horizontal direction, and no additional installation space or size is required on the premise of meeting the vibration isolation strength requirements.

[0051] In some embodiments, the energy dissipation mechanism 5 includes a movable shaft 51, a pressure elastic member 52, and an external pressure rod 53 which are coaxially arranged in sequence, the front end of the movable shaft 51 abuts against the peripheral side surface of the central shaft 4, the rear end of the movable shaft 51 abuts against the front end of the external pressure rod 53 through the pressure elastic member 52, and the rear end of the external pressure rod 53 is connected to the peripheral side wall of the cover body 2. Specifically, the front end of the movable shaft 51 extends from the horizontal receiving hole 17 into the central receiving groove 13 and abuts against the peripheral side surface of the central shaft 4, and the rear end of the movable shaft is located in the horizontal receiving hole 17 and abuts against the pressure elastic member 52; when the central shaft 4 produces a vertical displacement, the movable shaft 51 can be forced to produce a horizontal movement in the horizontal receiving hole 17 and compress the pressure elastic member 52, thereby further dissipating the vertical vibration energy.

[0052] In addition, the outer pressure rod 53 is located in the horizontal receiving hole 17, and the front end of the outer pressure rod 53 is in contact with the pressure elastic member 52, and the rear end of the outer pressure rod 53 extends out of the horizontal receiving hole 17 and is connected to the peripheral side wall of the cover body 2. When the cover body 2 is vertically displaced, the peripheral side wall of the cover body 2 can move relative to the outer pressure rod 53, and can limit the displacement of the outer pressure rod 53 relative to the cover body 2 in the horizontal direction, so that the pressure elastic member 52 can be compressed by the movable shaft 51; when the cover body 2 is horizontally displaced, the movable shaft 51 remains stationary by means of contact with the central axis 4, and the outer pressure rod 53 can be horizontally displaced with the cover body 2, so that the pressure elastic member 52 can be compressed by the outer pressure rod 53 to dissipate the horizontal and lateral vibration energy. In this design, there is a lateral gap 62 between the peripheral side wall of the cover body 2 and the base 1 to allow the lateral displacement of the cover body 2.

[0053] When the cover body 2 is vertically displaced due to vibration energy, the center axis 4 can only move in the vertical direction along the limiting axis 14 due to the horizontal restriction of the limiting axis 14 on the center axis 4; at the same time, since the peripheral side wall of the cover body 2 can limit the horizontal displacement of the external pressure rod 53 relative to the cover body 2, when the cover body 2 is vertically displaced due to vibration energy, the external pressure rod 53 is fixed. At this time, since the center axis 4 can move vertically along the limiting axis 14, the movable axis 51 can be pushed to make a linear motion in the horizontal accommodating hole 17, so that the pressure elastic member 52 is pressed by the movable axis 51, and the vibration energy in the vertical direction is dissipated.

[0054] When the cover body 2 generates horizontal lateral displacement due to vibration energy, the central axis 4 is limited by the limiting axis 14 to remain stationary, and the movable axis 51 also remains stationary due to the contact with the central axis 4. Since the external pressure rod 53 can move synchronously with the cover body 2 to generate horizontal lateral displacement, the pressure elastic member 52 can be compressed by the external pressure rod 53 to dissipate the vibration energy in the horizontal direction.

[0055] That is to say, in this design, the energy dissipation mechanism 5 can not only dissipate the vibration energy in the vertical direction, but also dissipate the vibration energy in the horizontal direction. Specifically, when the cover body 2 is vertically displaced due to the vibration energy, the outer pressure rod 53 of the energy dissipation mechanism 5 remains stationary, and at this time, the movable shaft 51 compresses the pressure elastic member 52 under the drive of the central shaft 4, thereby dissipating the vibration energy in the vertical direction; and when the cover body 2 is horizontally displaced due to the vibration energy, the movable shaft 51 remains stationary due to the contact with the central shaft 4, and at this time, the outer pressure rod 53 compresses the pressure elastic member 52 under the driving action of the horizontal and lateral movement of the cover body 2, thereby dissipating the vibration energy in the horizontal direction.

[0056] It should be noted that, in this embodiment, the peripheral side surface of the central shaft 4 has a working section 42 for cooperating with the movable shaft 51, and the radial cross section of the working section 42 gradually increases from the middle part to the two ends in the vertical direction, so that the surface or line where the working section 42 contacts each movable shaft 51 is an arc structure. This structure can more effectively disperse and absorb vibration energy by using the arc contact surface. Due to the increase in the contact area, the vibration energy can be more evenly distributed on the contact surface, and then the energy is gradually dissipated through the deformation of the pressure elastic member 52, thereby improving the energy absorption and buffering capacity of the entire mechanism. Since the arc structure enhances the stability and uniformity of the contact and optimizes the energy transfer and dissipation process, it can significantly reduce the damage of components caused by factors such as excessive wear and stress concentration, which helps to extend the service life of the entire energy dissipation mechanism 5.

[0057] In the above embodiment, the peripheral side wall of the cover body 2 is provided with a strip hole 23 corresponding to the external pressure rod 53 in the vertical direction, and the rear end of the external pressure rod 53 extends out of the strip hole 23; the peripheral side wall of the cover body 2 is also provided with a locking member 54 and a blocking member 55, the locking member 54 is screwed with the rear end of the external pressure rod 53, and the blocking member 55 blocks the outer side of the locking member 54. Specifically, by providing the strip hole 23 extending in the vertical direction on the peripheral side wall of the cover body 2, the rear end of the external pressure rod 53 passes through the strip hole 23, and the provision of the strip hole 23 allows a gap between the external pressure rod 53 and the peripheral side wall of the cover body 2 in the vertical direction, so that when the cover body 2 is vertically displaced, the peripheral side wall of the cover body 2 can be vertically displaced relative to the external pressure rod 53. In addition, a mounting groove is provided on the peripheral side wall of the cover body 2 at the mounting position corresponding to the external pressure rod 53, and a locking member 54 is provided in the mounting groove and is threadedly connected to the external pressure rod 53, and the locking member 54 can be a gasket; the blocking member 55 blocks the locking member 54 in the mounting groove from the outside to limit the horizontal displacement of the external pressure rod 53 relative to the cover body 2; the groove wall of the mounting groove and the locking member 54 have a second vertical gap 63 in the vertical direction, so that when the cover body 2 produces a vertical displacement, the peripheral side wall of the cover body 2 can move vertically relative to the external pressure rod 53.

[0058] It should be noted that the locking member 54 is arranged in the installation groove of the side wall of the cover body 2. Since there is a gap in the vertical direction between the locking member 54 and the installation groove, and there is a strip hole 23 on the side wall of the cover body 2 for the external pressure rod 53 to pass through, when the cover body 2 is vertically displaced, there will be no interference with the locking member 54 and the external pressure rod 53; in addition, due to the setting of the blocking member 55, the locking member 54 is located between the blocking member 55 and the bottom of the installation groove in the horizontal direction, so that when the cover body 2 is horizontally displaced, the locking member 54 and the external pressure rod 53 can be driven to produce a basically synchronous horizontal displacement.

[0059] In the above embodiment, the rotation of the locking member 54 around its own axis is restricted in the installation groove, so that the external pressure rod 53 can be screwed to adjust the depth of its insertion into the horizontal receiving hole 17, thereby facilitating the adjustment of the pre-pressure of the pressure elastic member 52. Specifically, the groove wall of the installation groove forms a restriction on the rotation of the locking member 54, so that the locking member 54 cannot be rotated in the installation groove, which can be restricted by the lateral side wall of the installation groove, that is, the gap between the lateral side wall of the installation groove and the locking member 54 is not enough to allow the locking member 54 to rotate. Due to this restriction, when the external pressure rod 53 is screwed by means of the threaded connection with the locking member 54, the locking member 54 remains stationary, while the external pressure rod 53 can be screwed in or out relative to the locking member 54, thereby achieving the purpose of adjusting the depth of the external pressure rod 53 inserted into the horizontal receiving hole 17. By adjusting the depth of the external pressure rod 53 extending into the horizontal receiving hole 17, the pre-pressure of the external pressure rod 53 on the pressure elastic member 52 can be adjusted, thereby adjusting the damping force of the entire device.

[0060] It can be understood that a vibration isolation groove 18 coaxially connected to the horizontal receiving hole 17 is provided on the side wall of the base 1, and a horizontal elastic member 56 is sleeved on the external pressure rod 53, and the two ends of the horizontal elastic member 56 respectively abut against the inner side wall of the cover body 2 and the bottom of the vibration isolation groove 18. Specifically, a horizontal elastic member 56 is also sleeved on the external pressure rod 53, and the horizontal elastic member 56 is located in the vibration isolation groove 18, and the rear end of the horizontal elastic member 56 abuts against the inner side wall of the cover body 2, and the front end of the horizontal elastic member 56 abuts against the bottom of the vibration isolation groove 18. When the cover body 2 generates a horizontal lateral displacement, the horizontal elastic member 56 can be compressed, so that the horizontal vibration energy can be further dissipated with the help of the horizontal elastic member 56.

[0061] Based on the same concept, the present application also provides a vehicle, comprising the vehicle engine suspension mounting bracket as described above.

[0062] In summary, the vehicle engine suspension mounting bracket and the vehicle provided by the utility model form two-stage vibration reduction by means of the first vibration reduction component and the second vibration reduction component. The vehicle engine suspension mounting bracket will dissipate energy for the vibration generated by the engine to isolate the transmission of the vibration to the vehicle body, thereby meeting the occasions with higher vibration isolation requirements; and, due to the presence of the second vibration reduction component, the vibration energy in the vertical direction can be dissipated by means of the energy dissipation mechanism 5 arranged in the horizontal direction, thereby changing the limitation in the direction of the vibration energy. Compared with the method of dissipating the vertical vibration energy by vertically arranging the energy dissipation mechanism 5 in the prior art, the overall layout of the vibration reduction device is more reasonable, and can make full use of the space in the horizontal direction, while reducing the volume or size of the vibration reduction device in the vertical direction, so that the structure of the vibration reduction device is more compact and can be better adapted to the cramped space for engine installation.

[0063] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
