Description
Technical Field
[0001] This utility model relates to the field of vehicle parts technology, and in particular to a shock absorption device and a vehicle. Background Technology
[0002] The wire displacement sensor is an ingenious structural design that combines the advantages of angle sensors and linear displacement sensors. It is a sensor with small installation size, compact structure, large measurement stroke, and high accuracy, with a stroke ranging from hundreds of millimeters to tens of meters.
[0003] Cable displacement sensors are typically mounted on vehicle shock absorbers via brackets, pulleys, and other components. The cable of the sensor is connected to the shock absorber strut mount at the top of the shock absorber. Because the shock absorber strut mount is connected to the vehicle body, when the cable displacement sensor rotates with the shock absorber body, the shock absorber strut mount remains stationary, causing the cable of the sensor to become misaligned, resulting in inaccurate data measured by the cable displacement sensor. Utility Model Content
[0004] This application addresses the shortcomings of existing methods by providing a shock absorption device and vehicle to solve the technical problem in the prior art where, when the cable displacement sensor rotates with the shock absorber body, the shock absorber support remains stationary, causing the cable of the cable displacement sensor to become skewed, resulting in inaccurate data measured by the cable displacement sensor.
[0005] In a first aspect, embodiments of this application provide a shock absorption device installed in a vehicle, which mainly includes a shock absorber, a cable connecting ring, a sensor, and a cable.

[0006] As an optional implementation, the vibration damping device further includes a bearing and a vibration isolation pad; the bearing, the pull wire connecting ring, and the vibration isolation pad are stacked on top of each other, moving away from the vibration damping support along the axial direction of the pull wire connecting ring.
[0007] As an optional implementation, both the bearing and the vibration isolation pad are annular; the bearing, the pull wire connecting ring, and the vibration isolation pad are coaxial; a limiting post protruding axially is formed on the side of the bearing facing the pull wire connecting ring; the pull wire connecting ring and the vibration isolation pad are both sleeved on the outside of the limiting post.

[0030] like Figure 1-2As shown, this application embodiment provides a shock absorption device installed in a vehicle, which mainly includes a shock absorber 1, a cable connecting ring 2, a sensor 3, and a cable 4. The shock absorber 1 includes a shock absorber strut seat 11 connected to the vehicle body, and a shock absorber body 12 connected to the shock absorber strut seat 11 and in a columnar shape; the shock absorber body 12 can rotate relative to the shock absorber strut seat 11 around the axis of the shock absorber body 12; the cable connecting ring 2 is coaxially sleeved on part of the outer side of the shock absorber body 12 and close to the shock absorber strut seat 11; the sensor 3 is fixed to the shock absorber body 12 and spaced apart from the cable connecting ring 2; the cable 4 connects the cable connecting ring 2 and the sensor 3, and the cable 4 is parallel to the axis of the shock absorber body 12; the cable 4, the sensor 3, the cable connecting ring 2, and the shock absorber body 12 remain relatively stationary.
[0031] Based on the aforementioned embodiments, in this embodiment, the damping body 12 is the non-dampening support 11 portion of the shock absorber 1. The damping body 12 includes existing structures such as springs, buffer blocks, dust covers, and piston rods. The damping body is vertically arranged, and the damping support 11 is located at the top of the damping body 12. The bottom end of the damping body 12 is used to connect to the steering knuckle. The damping body 12 can rotate relative to the damping support 11 about its own axial direction.
[0032] The two ends of the pull wire 4 are connected to the sensor 3 body and the pull wire connecting ring 2, respectively, and the pull wire 4 is parallel to the axis of the damping body 12. During the rotation of the damping body 12 around its axis, the pull wire 4, sensor 3, and pull wire connecting ring 2 rotate synchronously with the damping body 12. The pull wire 4, sensor 3, pull wire connecting ring 2, and damping body 12 remain relatively stationary, and the pull wire 4 remains parallel to the axis of the damping body 12. This avoids inaccurate measurements by the sensor 3 caused by the skewness of the pull wire 4.
[0033] As an optional implementation, the vibration damping device also includes a bearing 5 and a vibration isolation pad 6; the bearing 5, the wire connecting ring 2 and the vibration isolation pad 6 are stacked together, moving away from the vibration damping support seat 11 along the axial direction of the wire connecting ring 2.
[0034] Based on the aforementioned embodiments, in this embodiment, the bearing 5, the wire connecting ring 2, and the vibration isolation pad 6 are arranged sequentially from top to bottom to ensure that the wire connecting ring 2 can rotate synchronously with the vibration damping body 12.
[0035] As an optional implementation, both the bearing 5 and the vibration isolation pad 6 are annular; the bearing 5, the wire connecting ring 2 and the vibration isolation pad 6 are coaxial; a limiting post protruding axially is formed on the side of the bearing 5 facing the wire connecting ring 2; the wire connecting ring 2 and the vibration isolation pad 6 are both sleeved on the outside of the limiting post.
[0036] Based on the aforementioned embodiments, in this embodiment, the limiting post of the bearing 5 extends downward and has a hollow structure. The pull wire connecting ring 2 and the vibration isolation pad 6 are both sleeved on the outside of the limiting post to ensure that the bearing 5, the pull wire connecting ring 2, and the vibration isolation pad 6 rotate synchronously.
[0037] As an optional implementation, the pull wire connecting ring 2 includes an annular body 21 and a connecting arm 22. The connecting arm 22 is connected to the annular body 21; the connecting arm 22 extends outward from the annular body 21, and the end of the connecting arm 22 away from the annular body 21 is connected to the pull wire 4.
[0038] Based on the aforementioned embodiments, in this embodiment, the annular body 21 and the connecting arm 22 are integrally formed. Both the annular body 21 and the connecting arm 22 are sheet-like and can have the same thickness. The connecting arm 22 extends outward from the annular body 21, moving the pull wire 4 away from the shock-absorbing body 12 and providing space for the pull wire 4 to remain taut.
[0039] As an alternative implementation, the connecting arm 22 is strip-shaped and extends radially along the annular body 21.
[0040] The above solution facilitates the processing and manufacturing of the wire connecting ring 2.
[0041] As an optional implementation, the vibration damping pad 6 includes an inner convex ring portion 61 protruding toward the bearing 5 and an outer concave ring portion 62 recessed in the opposite direction to the bearing 5. The outer concave ring portion 62 surrounds the outer side of the inner convex ring portion 61, and the inner convex ring portion 61 is in contact with the annular body 21 of the pull wire connecting ring 2.
[0042] Based on the aforementioned embodiments, in this embodiment, the vibration isolation pad 6 has a certain thickness, a through hole in the middle, and is horizontally positioned. The vibration isolation pad 6 is supported and connected to the pull wire connecting ring 2. The middle of the vibration isolation pad 6 is higher than its surroundings, meaning the inner convex ring portion 61 protrudes upwards from the outer concave ring portion 62, and the inner convex ring portion 61 and the outer concave ring portion 62 are integrally formed. The inner convex ring portion 61 is adapted to the annular body 21 of the pull wire connecting ring 2, and the inner convex ring portion 61 and the annular body 21 of the pull wire connecting ring 2 are supported and connected to achieve synchronous rotation of both.
[0043] As an alternative implementation, the inner convex ring 61 has an anti-slip structure on the side facing the pull wire connecting ring 2.
[0044] By adopting the above solution, the friction between the inner convex ring 61 and the pull wire connecting ring 2 is increased, which can prevent the pull wire 4 from being skewed due to the relative rotation of the vibration isolation pad 6 and the pull wire connecting ring 2.
[0045] As an alternative implementation, the inner convex ring 61 has a plurality of radially extending grooves 63 formed on the side facing the wire connecting ring 2 to form an anti-slip structure.
[0046] Based on the aforementioned embodiments, in this embodiment, the radially extending groove 63 is perpendicular to the circumferential direction. The uneven structure caused by the groove 63 forms sufficient friction on the pull wire connecting ring 2, which can prevent the pull wire 4 from being skewed due to relative rotation between the vibration isolation pad 6 and the pull wire connecting ring 2.
[0047] In some embodiments, the inner convex ring portion 61 has a plurality of radially extending protrusions on the side facing the pull wire connecting ring 2 to form an anti-slip structure.
[0048] As an optional implementation, bearing 5 is a planar bearing.
[0049] A thrust bearing, also known as a planar thrust bearing, is characterized by its ability to achieve high axial load and high rigidity within a very small space. A thrust bearing consists of a planar cage assembly with needle rollers, cylindrical rollers, or steel balls, and planar washers.
