Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbing equipment, and in particular relates to a shock absorber for a vehicle. Background Art

[0002] In order to quickly attenuate the vibration of the frame and body and improve the smoothness and comfort of the car, the car suspension system is generally equipped with shock absorbers. However, for some vehicles transporting large mechanical equipment, even if the car shock absorbers are installed, the shock absorption effect is not ideal when encountering poor road conditions. Since the transport vehicle has a large load and the inertia of the goods is also large, the vibration impact generated by the car body when encountering road bumps is also relatively large. Especially when transporting precision instruments or fragile items, the vibration impact generated by the car body on the goods is easy to cause damage to the goods, resulting in huge losses.

[0003] In the prior art, a spring base is usually used to reduce the above vibration. However, when the spring base is subjected to excessive vibration impact force due to a large load, the spring may be over-compressed, which not only reduces the service life of the spring base, but also seriously affects the shock absorption effect.

[0026] Please also read Figure 1 and Figure 5Now, the vehicle shock absorber provided by the utility model is described. The vehicle shock absorber comprises a base 1, a pressure plate 2, a telescopic mechanism 3 and a shock absorbing mechanism 4. The pressure plate 2 is slidably connected to the top of the base 1 along the up-down direction, and the pressure plate 2 is connected with an upwardly extending mounting screw 21; the telescopic mechanism 3 is connected between the base 1 and the pressure plate 2, and the telescopic mechanism 3 comprises a plurality of groups of scissor support assemblies 31 arranged along the up-down direction and connected in sequence; the shock absorbing mechanism 4 comprises a damping kit 41 and a shock absorbing spring 42 sleeved on the outer periphery of the damping kit 41, one end of the damping kit 41 is hinged to the base 1, and the other end is hinged to any scissor support assembly 31, and the main axis of the damping kit 41 is arranged at an angle to the horizontal plane.

[0027] Compared with the prior art, the vehicle shock absorber provided in this embodiment is connected to the transported goods 30 above the vehicle shock absorber by installing a screw rod 21. When the goods 30 are subjected to vibration and impact the pressure plate 2 downward during transportation, the multiple sets of scissor brace assemblies 31 are compressed and receive the downward movement of the pressure plate 2. In this process, the damping kit 41 hinged between the base 1 and the scissor brace assembly 31 and the shock absorbing spring 42 sleeved on the outer periphery of the damping kit 41 are compressed at the same time and generate a thrust force to resist the pressure of the scissor brace assembly 31 moving downward, thereby effectively buffering the vibration impact; the damping kit 41 can also absorb the bounce of the shock absorbing spring 42 when it rebounds, so that the pressure plate 2 and the goods 30 above it can be stably reset. Due to the angle between the main axis of the shock absorbing mechanism 4 and the horizontal plane, and the impact force on the pressure plate 2 is transmitted to the shock absorbing mechanism 4 after passing through the multiple sets of scissor brace assemblies 31, the shock absorbing spring 42 is prevented from being over-compressed, which helps to extend the service life of the vehicle shock absorber and improve the shock absorption effect.

[0028] In this embodiment, see Figure 5 The number of vehicle shock absorbers to be used and the installation position are determined according to the loading requirements of the cargo 30. For larger cargo 30, at least four vehicle shock absorbers in this embodiment are arranged at the bottom thereof to support the four corners of the cargo 30 respectively. Bolt holes are arranged on the base 1, which can be connected to the carriage 20 by bolts. When loading the cargo 30, a connecting plate 10 can be arranged at the bottom of the cargo 30. By connecting the mounting screw 21 with the connecting plate 10, the cargo 30 is supported on the top of the pressure plate 2, so as to achieve shock absorption during the loading and transportation of the cargo 30. Furthermore, a connecting plate 10 can also be arranged at the front of the cargo 30, and the vehicle shock absorber in this embodiment is arranged between the connecting plate 10 and the front baffle of the carriage 20 to prevent the cargo 30 from colliding with the carriage 20 in the direction of travel.

[0029] The telescopic mechanism 3 adopts a scissor brace structure and is configured as two groups of scissor brace components 31 connected up and down, which can make the buffering process smoother and more stable. The scissor brace structure is a prior art and will not be described in detail here.

[0030] It should be noted that the shock absorbing mechanism 4 is hinged between the base 1 and the scissors strut assembly 31, and the inclination angle of its axis changes with the extension and retraction of the telescopic mechanism 3. At the same time, the telescopic mechanism 3 decomposes the downward vibration impact of the cargo 30 into oblique pressure and applies it to the shock absorbing mechanism 4, avoiding the vibration impact force directly impacting the shock absorbing spring 42, which helps to extend the service life of the shock absorbing spring 42.

[0031] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 1 and Figure 3 The damping kit 41 includes a damping cylinder 411 hinged on the base 1 and a damping rod 412 slidably connected to the damping cylinder 411. The upper end of the damping rod 412 is hinged to the scissors support assembly 31. The shock-absorbing spring 42 is sleeved on the outer periphery of the damping cylinder 411, and the two ends of the shock-absorbing spring 42 are respectively connected to the outer peripheral walls of the damping cylinder 411 and the damping rod 412. The shock-absorbing spring 42 can be stretched or compressed under the drive of the damping rod 412.

[0032] In this embodiment, when the pressure plate 2 is subjected to a downward vibration impact, the scissors strut assembly 31 contracts and moves downward, driving the damping kit 41 to swing downward around the hinge point with the base 1, while the damping rod 412 slides inward and contracts along the damping cylinder 411, and the shock-absorbing spring 42 is synchronously compressed to generate a thrust force. At the same time, the damping kit 41 generates a damping force due to the throttling characteristics of its internal structure, so that the contraction process of the damping rod 412 is effectively buffered, thereby achieving the effect of buffering the vibration impact force; when the vibration impact force disappears, the scissors strut assembly 31 drives the pressure plate 2 to move upward under the action of the thrust of the shock-absorbing spring 42, and the damping kit 41 swings upward around the hinge point with the base 1, while the damping rod 412 slides outward along the damping cylinder 411, and the damping kit 41 generates a damping force to slow down the extension process of the damping rod 412, so that the pressure plate 2 is stably reset, avoiding the bouncing phenomenon caused by the rebound of the shock-absorbing spring 42.

[0033] The throttling characteristics of the damping kit 41 are prior art and will not be described in detail here. However, the technical solution of the damping kit 41 cooperating with the shock absorbing spring 42 and connecting with the telescopic mechanism 3 to achieve vibration shock buffering belongs to the protection scope of the present utility model.

[0034] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 3 A circumferentially extending annular baffle 413 is provided on the outer peripheral wall of the damping rod 412, and a sleeve 414 extending toward one side of the damping cylinder 411 and coaxially arranged with the damping rod 412 is provided on the side wall of the annular baffle 413. The upper end of the shock absorbing spring 42 is sleeved on the outer periphery of the sleeve 414 and fixedly connected to the annular baffle 413.

[0035] In this embodiment, the upper end of the shock absorbing spring 42 is fixedly connected to the annular baffle 413, so that the shock absorbing spring 42 can be stretched or compressed synchronously with the sliding of the damping rod 412, and the synchronous action of the two optimizes the buffering effect. The sleeve 414 extends along the axial direction of the damping rod 412 to guide the action of the shock absorbing spring 42 to a certain extent, preventing the axis of the shock absorbing spring 42 from shifting during action to form a deflection torque, causing the shock absorbing spring 42 to twist and deform, thereby reducing its service life.

[0036] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 3 An elastic buffer block 415 is provided in the sleeve 414 and is sleeved on the outer periphery of the damping rod 412 . The axial height of the elastic buffer block 415 is greater than the axial height of the sleeve 414 .

[0037] In this embodiment, the elastic buffer block 415 is a rubber elastic member, and the elastic buffer block 415 is arranged inside the sleeve 414 to prevent the shock absorbing spring 42 from instantly deforming and causing shear damage to the elastic buffer block 415 when the vehicle shock absorber is subjected to a large vibration impact.

[0038] The elastic buffer block 415 is fixed inside the sleeve 414, and its axial height is greater than the axial height of the sleeve 414, that is, the elastic buffer block 415 is axially protruding from the sleeve 414. When the damping rod 412 slides and contracts into the damping cylinder 411, the elastic buffer block 415 first contacts the damping cylinder 411 and withstands impact deformation, thereby avoiding excessive contraction of the damping rod 412 and helping to improve the buffering effect.

[0039] Furthermore, the elastic buffer block 415 is a conical structure, that is, the outer diameter of the elastic buffer block 415 is smaller than the inner diameter of the sleeve 414, so that the elastic buffer block 415 has sufficient deformation space inside the sleeve 414 when impacted, thereby avoiding shear damage to the elastic buffer block 415 by the end wall of the sleeve 414.

[0040] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 3 A plurality of grooves 4151 arranged axially at intervals are provided on the inner circumferential wall of the elastic buffer block 415 , and the grooves 4151 extend along the circumferential direction of the elastic buffer block 415 .

[0041] In this embodiment, the setting of the groove 4151 provides a certain deformation space for the thermal expansion and contraction of the elastic buffer block 415, while reducing the contact area between the elastic buffer block 415 and the damping rod 412, thereby avoiding the formation of extrusion friction between the elastic buffer block 415 and the damping rod 412, resulting in a reduction in the service life of the elastic buffer block 415.

[0042] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 3An adjusting seat 416 is provided on the outer thread sleeve of the damping cylinder 411 , and the lower end of the shock absorbing spring 42 is pressed against the side wall of the adjusting seat 416 .

[0043] In this embodiment, by rotating the adjustment seat 416 to slide along the axis of the damping cylinder 411 , the compression degree, ie, the hardness or softness, of the shock absorbing spring 42 can be adjusted to adapt to vibration impact forces in different ranges.

[0044] It should be noted that the shock-absorbing spring 42 can only expand and contract axially with the sliding of the adjustment seat 416 , and cannot rotate synchronously with the adjustment seat 416 , so as to avoid the shock-absorbing spring 42 from twisting and deforming to form a deflection torque, thereby affecting the buffering effect of the shock-absorbing spring 42 .

[0045] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 1 and Figure 2 Each set of scissor support assemblies 31 includes two scissor groups correspondingly arranged in the front and rear and a top support rod 313 connected between the two scissor groups. The upper end of the damping rod 412 is hinged to the top support rod 313. The scissor group includes a first scissor arm 311 and a second scissor arm 312 hinged to each other. The lower end of the first scissor arm 311 located at the bottom is slidably connected to the base 1, and the upper end of the second scissor arm 312 located at the top is slidably connected to the pressure plate 2.

[0046] In this embodiment, each group of scissors support assemblies 31 includes two scissor groups correspondingly arranged front and back, and each scissor group includes a first scissor arm 311 and a second scissor arm 312 hinged to each other. The front and rear corresponding arrangement of the scissor groups increases the supporting stability of the pressure plate 2. The hinged structure of the scissor group is a prior art and will not be elaborated here.

[0047] The top support rod 313 is connected between the two corresponding front and rear scissor groups, and can be connected between the two corresponding front and rear first scissor arms 311, or can be connected between the two corresponding front and rear second scissor arms 312, which is not specifically limited here. The upper end of the damping rod 412 is hinged on the top support rod 313, so that the scissor support assembly 31 can press the damping rod 412 downward to retract, and vice versa, the damping spring 42 can push the scissor support assembly 31 to reset, thereby realizing the buffer connection between the telescopic mechanism 3 and the damping mechanism 4.

[0048] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 1 and Figure 2 A sliding rod 11 extending in the horizontal direction is respectively provided on the base 1 and the pressure plate 2, and a sliding ring 314 slidably sleeved with the sliding rod 11 is respectively provided at the lower end of the first scissor arm 311 located at the bottom and the upper end of the second scissor arm 312 located at the top, and a buffer spring 13 abutting against the side of the sliding ring 314 is provided on the outer periphery of the sliding rod 11.

[0049] In this embodiment, a mounting seat 12 is respectively provided on the base 1 and the pressure plate 2, the sliding rod 11 is fixed on the mounting seat 12, and the sliding ring 314 is fixedly connected to the side wall of the first scissor arm 311 or the second scissor arm 312. Through the sliding cooperation between the sliding ring 314 and the sliding rod 11, a sliding connection is realized between the first scissor arm 311 and the base 1 and between the second scissor arm 312 and the pressure plate 2, so as to realize the telescopic function of the telescopic mechanism 3.

[0050] The buffer spring 13 is sleeved on the sliding rod 11 and abuts between the sliding ring 314 and the mounting seat 12 to buffer the sliding process of the sliding ring 314 and further buffer the telescopic process of the telescopic mechanism 3, which helps to improve the shock absorption effect.

[0051] In some possible implementations, the sliding rod 11 is threadedly connected with an adjusting nut 15, and the buffer spring 13 abuts between the sliding ring 314 and the adjusting nut 15. The adjustment of the telescopic length of the buffer spring 13 is achieved by rotating the adjusting nut 15 to adjust the buffering force of the buffer spring 13. The specific adjustment principle is the same as the above-mentioned adjustment seat 416, which will not be repeated here.

[0052] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 2 The base 1 has two side upright plates 14 extending upward, and the adjacent side walls of the two side upright plates 14 are respectively provided with limit grooves 141 extending in the up-down direction, and the two end surfaces of the pressure plate 2 are respectively provided with extended bosses 22 corresponding to and slidingly matched with the limit grooves 141.

[0053] In this embodiment, when the pressure plate 2 slides downward due to vibration impact and slides upward to return to its original position under the pushing action of the shock-absorbing spring 42, the extended boss 22 slides in the corresponding limit groove 141, guiding the pressure plate 2 and preventing the pressure plate 2 from shaking back and forth when sliding up and down.

[0054] Furthermore, a rubber pad is provided on the groove wall of the limiting groove 141 to prevent the extended boss 22 from colliding with the groove wall of the limiting groove 141 and generating vibration, thereby ensuring a shock-absorbing effect.

[0055] As a specific implementation of the vehicle shock absorber provided by the utility model, see Figure 1 and Figure 4 A horizontally extending T-slot slideway 23 is provided on the top surface of the pressure plate 2, and a T-shaped downturn 211 that slides with the T-slot slideway 23 is connected to the bottom end of the mounting screw 21.

[0056] In this embodiment, a T-slot slide 23 is provided on the pressure plate 2, so that the mounting screw 21 can move horizontally along the T-slot slide 23 to adjust the installation position of the vehicle shock absorber and the cargo 30 above the pressure plate 2, thereby improving the applicability of the vehicle shock absorber.

[0057] It should be noted here that the width of the connecting plate 10 needs to be adapted to the width of the pressure plate 2 , so that the pressure plate 2 can support the cargo 30 and move downward to cushion vibration without being blocked by the two side plates 14 .

[0058] 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.
