Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, and in particular relates to a vibration reduction mechanism and an automobile. Background Art

[0002] In the car modification market, car enthusiasts hope to be able to manually adjust the vehicle's posture to adapt to different car usage needs. For example, when racing on a flat road, car enthusiasts will manually lower the vehicle's posture to make the car look better. When it is necessary to drive on an uneven road, the user will correspondingly raise the vehicle's posture to adapt to the relevant road conditions. Since the front shock absorber is generally installed above the wheel and the rear shock absorber is installed on the side of the wheel, when adjusting the vehicle's posture, most of the time, the vehicle needs to be raised first, and then the wheel is removed and adjusted with tools. At the same time, the tire needs to be installed and the vehicle lowered before the vehicle posture can be measured to confirm whether it is correct. This method of adjusting the height of the car has the problem of difficult operation. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in view of the problem that the method of adjusting the height of a car in the prior art is difficult to operate, a vibration reduction mechanism and a car are provided.

[0004] In order to solve the above technical problems, on the one hand, an embodiment of the present invention provides a shock absorbing mechanism, including a mounting frame, a shock absorbing spring, a shock absorber and a posture adjustment assembly for adjusting the height of a vehicle body, wherein the mounting frame is installed on an external vehicle body, the shock absorber includes an outer cylinder and a piston rod installed in the outer cylinder; the shock absorbing spring is sleeved on the outer cylinder and abuts between the outer cylinder and the posture adjustment assembly; the posture adjustment assembly is installed in the mounting frame and can move relative to the mounting frame along the axial direction of the shock absorber; the upper end of the piston rod is slidably installed on the posture adjustment assembly along the axial direction of the shock absorber.

[0005] According to the damping mechanism of the present invention, the mounting frame is mounted on the external vehicle body, and one end of the damper away from the damping spring is connected to the external steering knuckle or other structure. The damping spring can drive the vehicle body to move up and down relative to the wheel by the posture adjustment component moving along the axial direction of the damper in the mounting frame, thereby realizing the adjustment of the height of the vehicle. Most of the conventional dampers are mounted on the bottom of the vehicle body, which is inconvenient to debug. The setting of the posture adjustment component in the device can make the structure of the device used for adjusting the height of the vehicle body extend one end distance in the direction away from the bottom of the vehicle, thereby facilitating the operator to debug the height of the vehicle body. For example, when the device acts on the front wheel, the mounting frame is mounted on the vehicle body near the front wheel, the posture adjustment component is mounted on the mounting frame, and the upper part of the posture adjustment component is exposed through the mounting frame. In this way, the top position of the posture adjustment component can be located near the engine. In this way, when the operator is debugging the height of the vehicle body near the front wheel, the operator only needs to open the front hood to find the posture adjustment component, and then the corresponding position of the vehicle posture can be adjusted by controlling the position of the posture adjustment component in the through hole. Similarly, through this device, the operator can adjust the corresponding position of the vehicle posture by opening the rear trunk. At the same time, most traditional shock absorbers adjust the height of the vehicle body by adjusting the bottom of the shock absorber spring to move it up and down. This device adjusts the height of the vehicle body by adjusting the top of the shock absorber spring to move up and down. Through this device, there is no need to lift the vehicle body or remove the tires, and the vehicle posture can be measured in real time. This device is simple to operate, accurate, and has a fast adjustment time.

[0006] Optionally, the posture adjustment assembly includes a first hollow structure, and the piston rod is installed in the first hollow structure and can move along the axial direction of the shock absorber. When the car encounters uneven ground during driving, this can effectively reduce vibration.

[0007] Optionally, it also includes a stroke adjustment component for adjusting the piston rod jump stroke, the stroke adjustment component is installed in the first hollow structure and can move along the axial direction of the shock absorber; the stroke adjustment component is provided with a channel corresponding to the piston rod, the upper end of the piston rod can be slidably installed in the channel, and the outer cylinder can abut against the stroke adjustment component.

[0008] Optionally, the first hollow structure is provided with a first internal thread, and the stroke adjustment component is provided with a first external thread matching the first internal thread. In this embodiment, the stroke adjustment component is threadedly connected to the posture adjustment component, and the stroke adjustment component is moved up and down in the posture adjustment component by twisting the stroke adjustment component.

[0009] Optionally, a buffer block for limiting the stroke of the piston rod is provided at the bottom of the stroke adjustment assembly, a gap is left between the buffer block and the outer tube, and the buffer block can abut against the outer tube. In this embodiment, the abutment between the buffer block and the outer tube can prevent the piston rod and the suspension from further jumping upward. In this embodiment, by twisting the stroke adjustment assembly, the stroke adjustment assembly drives the buffer block to move in the up and down direction relative to the posture adjustment assembly, the size of the gap distance between the buffer block and the outer tube can be adjusted, and then the stroke of the piston rod and the suspension jumping up and down can be adjusted.

[0010] Optionally, a bearing for preventing the piston rod from rotating is provided at the bottom of the posture adjustment assembly, the piston rod is installed in the inner ring of the bearing, and the first hollow structure is fixed to the outer ring of the bearing. In this embodiment, the shock absorber has the function of a common shock absorber of the suspension, and the bearing has the function of a common bearing on the suspension. The setting of the bearing ensures that the posture adjustment assembly will not drive the piston rod to rotate when it rotates relative to the mounting frame, thereby ensuring the feasibility of the implementation of the posture adjustment assembly in this solution to drive the outer cylinder of the shock absorber and the stroke adjustment assembly to drive the piston rod of the shock absorber to move in the up and down directions, but will not drive them to rotate.

[0011] Optionally, a locking assembly for locking the position of the stroke adjustment assembly is further included, the locking assembly is arranged at the top of the stroke adjustment assembly, and a notch for twisting the locking assembly is provided on the locking assembly. In this embodiment, the limiter assembly includes a limiter and a fixed cover, the limiter is a hollow cylindrical structure, and there is a hexagonal space in the upper plane, and the limiter can cooperate with the stroke adjustment assembly. The fixed cover is a flat plate structure, the edge is a threaded structure, and the notch (hexagonal hole) described above is provided in the middle.

[0012] Optionally, the mounting frame is provided with a through hole, the through hole is provided with a second internal thread, and the posture adjustment component is provided with a second external thread matching the second internal thread.

[0013] Optionally, a hinge ring for locking the posture adjustment component is further included, the hinge ring being threadedly connected to the posture adjustment component and being able to abut against the mounting frame. In this embodiment, when the hinge ring is screwed onto the posture adjustment component and abuts against the mounting frame, under the action of the friction force between the hinge ring and the mounting frame, the posture adjustment component cannot be screwed out of the mounting frame by directly twisting it. The provision of the hinge ring can increase the stability of the connection between the posture adjustment component and the mounting frame.

[0014] On the other hand, an embodiment of the present invention provides a car, comprising the above-mentioned vibration reduction mechanism.

[0015] In this embodiment, the mounting frame is mounted on the vehicle body by bolts, and one end of the shock absorber away from the shock absorber spring is connected to the steering knuckle. The operator can adjust the posture of the whole vehicle by twisting the posture adjustment component to move the bearing and the shock absorber spring up and down. For example, by twisting the posture adjustment component clockwise to move the bearing and the shock absorber spring downward, the shock absorber, the steering knuckle and the wheel connected to the shock absorber spring will move downward relative to the vehicle body. When the vehicle is not raised, because the vehicle is parked on the ground and the wheels are not moving, the reaction force applied by the wheels will move the vehicle body upward, thereby raising the vehicle body. In this embodiment, the up and down movement of the vehicle body will bring the mounting frame up and down, but because the posture adjustment component moves up and down relative to the mounting frame, the vehicle body will rise or fall one end relative to the wheel to balance the up and down movement of the posture adjustment component in the mounting frame. At the same time, in this embodiment, by twisting the stroke adjustment component, the buffer block can be driven to move up and down, thereby adjusting the stroke of the piston rod and the up and down jumping of the suspension.

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figures 1 to 4As shown, an embodiment of the present invention provides a vibration reduction mechanism, including a mounting frame 1, a vibration reduction spring 2, a shock absorber 3 and a posture adjustment component 4 for adjusting the height of a vehicle body, wherein the mounting frame 1 is mounted on an external vehicle body, the shock absorber includes an outer cylinder 31 and a piston rod 32 installed in the outer cylinder 31; the vibration reduction spring 2 is sleeved on the outer cylinder 31 and abuts between the outer cylinder and the posture adjustment component; the posture adjustment component 4 is installed in the mounting frame 1 and can move relative to the mounting frame 1 along the axial direction of the shock absorber; the upper end of the piston rod 32 is slidably installed on the posture adjustment component 4 along the axial direction of the shock absorber 3.

[0024] In this embodiment, the mounting frame 1 is mounted on the external vehicle body, and the end of the shock absorber 3 away from the shock absorbing spring 2 is connected to the external steering knuckle or other structure. The posture adjustment component 4 moves along the axial direction of the shock absorber 3 in the mounting frame 1, so that the shock absorbing spring 2 can drive the vehicle body to move up and down relative to the wheel, thereby realizing the adjustment of the height of the vehicle. Most of the traditional shock absorbers are installed at the bottom of the vehicle body, which is not convenient for debugging. The setting of the posture adjustment component 4 in the present device can make the structure of the present device for adjusting the height of the vehicle body extend a distance away from the bottom of the vehicle, thereby facilitating the operator to debug the height of the vehicle body. For example, when the present device acts on the front wheel, the mounting frame 1 is mounted on the vehicle body near the front wheel, the posture adjustment component 4 is mounted on the mounting frame 1, and the upper part of the posture adjustment component 4 is exposed through the mounting frame 1. In this way, the top position of the posture adjustment component 4 can be located near the engine. In this way, when the operator is adjusting the height of the vehicle body near the front wheel, the operator only needs to open the front hood to find the posture adjustment component 4, and then the corresponding position of the vehicle posture can be adjusted by controlling the position of the posture adjustment component 4 in the through hole 11. Similarly, through this device, the operator can adjust the corresponding position of the vehicle posture by opening the rear trunk. At the same time, most traditional shock absorbers adjust the height of the vehicle body by adjusting the bottom of the shock-absorbing spring 2 to move it up and down, and this device adjusts the height of the vehicle body by adjusting the top of the shock-absorbing spring 2 to move up and down. Through this device, there is no need to lift the vehicle body or remove the tire, and the vehicle posture can be measured in real time to see if it is correct. It is accurate and the adjustment time is fast.

[0025] In one embodiment, the posture adjustment assembly 4 includes a first hollow structure 41, and the piston rod 32 is installed in the first hollow structure 41 and can move along the axial direction of the shock absorber. When the car encounters uneven ground during driving, this can effectively reduce vibration.

[0026] In one embodiment, it also includes a stroke adjustment component 5 for adjusting the jumping stroke of the piston rod 32. The stroke adjustment component 5 is installed in the first hollow structure 41 and can move along the axial direction of the shock absorber 3; the stroke adjustment component 5 is provided with a channel 51 corresponding to the piston rod 32, the piston rod 32 of the shock absorber 3 can be slidably installed in the channel 51, and the outer cylinder 31 can abut against the stroke adjustment component 5.

[0027] In one embodiment, the first hollow structure 41 is provided with a first internal thread, and the stroke adjustment component 5 is provided with a first external thread matching the first internal thread. In this embodiment, the stroke adjustment component 5 is threadedly connected to the posture adjustment component 4, and the stroke adjustment component 5 is moved up and down in the posture adjustment component 4 by twisting the stroke adjustment component 5.

[0028] In one embodiment, a buffer block 6 for limiting the stroke of the piston rod 32 is provided at the bottom of the stroke adjustment component 5, and a gap 7 is left between the buffer block 6 and the outer tube 31, and the buffer block 6 can abut against the outer tube 31. In this embodiment, the abutment between the buffer block 6 and the outer tube 31 can prevent the piston rod 32 and the suspension from further jumping upward. In this embodiment, by twisting the stroke adjustment component 5, the stroke adjustment component 5 drives the buffer block 6 to move in the up and down direction relative to the posture adjustment component 4, the size of the gap 7 between the buffer block 6 and the outer tube 31 can be adjusted, and then the stroke of the piston rod 32 and the suspension jumping up and down can be adjusted.

[0029] In one embodiment, the bottom of the posture adjustment component 4 is provided with a bearing 8 for preventing the piston rod 32 from rotating, the piston rod 32 is installed in the inner ring of the bearing 8, and the first hollow structure 41 is fixed to the outer ring of the bearing 8. In this embodiment, the shock absorber 3 has the function of a common shock absorber of the suspension, and the bearing 8 has the function of a common bearing on the suspension. The setting of the bearing 8 ensures that the posture adjustment component 4 will not drive the piston rod 32 to rotate when it rotates relative to the mounting frame 1, thereby ensuring the feasibility of the implementation of the posture adjustment component 4 in this solution to drive the outer cylinder 31 of the shock absorber 3 and the stroke adjustment component 5 to drive the piston rod 32 of the shock absorber 3 to move in the up and down directions, but will not drive them to rotate.

[0030] In one embodiment, a locking assembly 9 for locking the position of the stroke adjustment assembly 5 is further included. The locking assembly 9 is arranged at the top of the stroke adjustment assembly 5, and a notch 91 for twisting the locking assembly 9 is provided on the locking assembly 9. In this embodiment, the limiter assembly includes a limiter 92 and a fixed cover 93. The limiter 92 is a hollow cylindrical structure with a hexagonal space in the upper plane, and the limiter 92 can cooperate with the stroke adjustment assembly 5. The fixed cover 93 is a flat plate structure with a threaded edge and a notch 91 (hexagonal hole) in the middle.

[0031] In one embodiment, the mounting frame 1 is provided with a through hole 11, the through hole 11 is provided with a second internal thread, and the posture adjustment component 4 is provided with a second external thread matching the second internal thread.

[0032] In one embodiment, a hinge tooth ring 10 for locking the posture adjustment component 4 is further included, and the hinge tooth ring 10 is threadedly connected to the posture adjustment component 4 and can abut against the mounting frame 1. In this embodiment, when the hinge tooth ring 10 is screwed on the posture adjustment component 4 and abuts against the mounting frame 1, under the action of the friction force between the hinge tooth ring 10 and the mounting frame 1, the posture adjustment component 4 cannot be screwed out of the mounting frame 1 by directly twisting the posture adjustment component 4. The provision of the hinge tooth ring 10 can increase the stability of the connection between the posture adjustment component 4 and the mounting frame 1.

[0033] In one embodiment, the damping spring 2 is a threaded spring. The damping mechanism also includes a dust cover 12 for dust prevention, one end of the dust cover 12 is sleeved on the buffer block 6, and the other end is sleeved on the outer cylinder 31. At the same time, the outer cylinder 31 is also provided with an abutment member, and the abutment member is provided with a mounting groove for facilitating the installation of the threaded spring; the bearing 8 is also provided with an arc groove for facilitating the abutment of the spiral spring. The threaded spring is sleeved on the damper 3, and the two ends of the threaded spring are respectively installed in the arc groove and the mounting groove. At the same time, the portion where the threaded spring is connected to the arc groove and the mounting groove is provided with a rubber pad.

[0034] In another embodiment, the vibration damping mechanism also includes a fixing nut and a bushing; the bushing is arranged in the stroke adjustment energy group, and the bushing is used to install the piston rod 32. At the same time, the piston rod 32 is fixed to the bushing by the fixing nut, so that the piston rod 32 installed with the bushing cannot jump out of the stroke adjustment assembly 5 when jumping up and down.

[0035] It should be noted that appropriate deformations made according to this solution are also within the protection scope of the present invention. For example, when installed on an elastic mechanism without a shock absorber, the stroke adjustment component, the limit component and other structures in the present invention can be cancelled. When installed on a mechanism with only a shock absorber but no shock-absorbing spring (such as a rear shock absorber), the tooth ring, the mounting frame and the posture adjustment component are only preferred and do not need to reflect the posture adjustment function, but only need to achieve stroke adjustment.

[0036] On the other hand, an embodiment of the present invention provides a car, comprising the above-mentioned vibration reduction mechanism.

[0037] In this embodiment, the mounting frame 1 is mounted on the vehicle body by bolts, and the end of the shock absorber 3 away from the shock absorbing spring 2 is connected to the steering knuckle. The operator can adjust the posture of the whole vehicle by twisting the posture adjustment component 4 to move the bearing 8 and the shock absorbing spring 2 up and down. For example, by twisting the posture adjustment component 4 clockwise to move the bearing 8 and the shock absorbing spring 2 downward, the shock absorber, the steering knuckle and the wheel connected to the shock absorbing spring 2 will move downward relative to the vehicle body. When the vehicle is not raised, because the vehicle is parked on the ground and the wheels are not moving, the reaction force applied by the wheels will cause the vehicle body to move upward, thereby raising the vehicle body. In this embodiment, the up and down movement of the vehicle body will bring the mounting frame 1 up and down, but because the posture adjustment component 4 moves up and down relative to the mounting frame 1, the vehicle body will rise or fall one end distance relative to the wheel to balance the up and down movement of the posture adjustment component 4 in the mounting frame 1. At the same time, in this embodiment, by twisting the stroke adjustment component 5, the buffer block 6 can be driven to move up and down, thereby adjusting the stroke of the piston rod 32 and the up and down jumping of the suspension. Preferably, in the present invention, the posture adjustment component 4 is turned clockwise to raise the vehicle body, and the posture adjustment component 4 is turned counterclockwise to lower the vehicle body. At the same time, the stroke adjustment component 5 is turned clockwise to reduce the stroke, and the stroke adjustment component 5 is turned counterclockwise to increase the stroke.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
