Abstract
Description
Technical Field
[0001] This application relates to the field of automotive shock absorber technology, and more particularly to a desktop automotive shock absorber. Background Technology
[0002] The shock absorber is a major suspension component that connects the air suspension to the vehicle frame. Its function is to provide damping characteristics for the suspension, absorb the energy of vertical vibration of the suspension, and convert it into heat energy for dissipation, thereby attenuating the vibration generated by the impact load during vehicle operation and improving the ride smoothness and comfort of the vehicle.
[0003] Existing desktop car shock absorbers use dust covers for protection during use. However, the dust covers are installed using limit screws, and parts are easily lost when the dust covers are disassembled for cleaning, which affects the installation of the dust covers. Therefore, a desktop car shock absorber is needed. Utility Model Content
[0004] The purpose of this application is to solve the problem that parts are easily lost during the installation and removal of dust covers.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a desktop car shock absorber, including an oil reservoir, a piston rod slidably connected inside the oil reservoir, a spring tray fixedly connected outside the oil reservoir, a second connector fixedly connected to the top of the piston rod, a first connector fixedly connected to the bottom of the oil reservoir, and an air spring installed between the second connector and the spring tray;
[0006] The bottom of the second connector has a limiting groove, and a dust cover is snapped into the limiting groove. The top of the dust cover has a first mounting groove, and a protrusion is provided inside the first mounting groove. A limiting post is fixedly connected inside the protrusion, and a limiting frame is slidably connected to the outside of the limiting post. A fixing plate is fixedly connected to the end of the limiting frame away from the protrusion. A circular groove is provided inside the fixing plate, and a connecting post is fixedly connected to the inner side wall of the fixing plate. A sliding shaft is slidably connected inside the connecting post, and an operating hole is provided inside the sliding shaft. A threaded post is fixedly connected to the end of the sliding shaft. A threaded groove is provided on the circumferential surface of the second connector, and the threaded post is threadedly connected to the inside of the threaded groove. When the device is in use, the fixed plate drives the limiting frame to slide outside the limiting column, so that the connecting column drives the threaded column away from the second connecting head through the sliding shaft. Then, the dust cover is put into the limiting groove at the bottom of the second connecting head. Then, the sliding shaft is rotated by the operating hole, so that the threaded column is threadedly connected to the threaded groove, thereby realizing the installation of the dust cover. Moreover, there is no need to disassemble the parts during the installation process, which helps to avoid the loss of parts.
[0007] Furthermore, multiple protrusions and limiting posts are provided, and each of the multiple limiting posts is fitted with a compression spring. The limiting frame is fitted outside the compression spring. When the limiting frame is displaced outward, it can compress the compression spring, causing the compression spring to generate a reaction force on the limiting frame, ensuring that the fixing plate remains inside the first mounting groove.
[0008] Furthermore, the dust cover includes a first outer cover, the interior of which has a sliding groove. A second outer cover is slidably connected inside the sliding groove, and the bottom of the second outer cover is in contact with the top of the spring tray. In use, the first and second outer covers provide overall protection for the device. The second outer cover can slide within the first outer cover via the sliding groove, facilitating movement in conjunction with the air spring and improving the dust cover's dust-proof efficiency.
[0009] Furthermore, the inner wall of the first outer cover is provided with a protruding ring, which engages with the inside of the limiting groove. The protruding ring can engage well with the limiting groove.
[0010] Furthermore, a displacement groove is formed inside the connecting column, and the sliding shaft fits against the inner wall of the displacement groove. The sliding shaft slides along the inner wall of the displacement groove, and can also rotate within it.
[0011] Furthermore, the operating hole is cross-shaped, and its position corresponds to the circular groove. The cross-shaped operating hole facilitates the rotation of the sliding shaft, thereby connecting the threaded column with the threaded groove.
[0012] Compared with the prior art, the beneficial effects of this application are as follows:
[0013] (1) Compared with the prior art, this kind of desktop car shock absorber is equipped with a limit post, a limit frame, a fixed plate, a connecting post, a sliding shaft and a threaded post. When the device is in use, the fixed plate drives the limit frame to slide outside the limit post, so that the connecting post drives the threaded post away from the second connector through the sliding shaft. Then the dust cover is fitted into the limit groove at the bottom of the second connector. Then the sliding shaft is rotated by the operating hole, so that the threaded post is threadedly connected to the threaded groove, thereby realizing the installation of the dust cover. Moreover, there is no need to disassemble the parts during the installation process, which helps to avoid the loss of parts.
[0014] (2) Compared with the prior art, the tabletop car shock absorber is equipped with a first outer cover and a second outer cover. When the device is in use, the first outer cover and the second outer cover are used to cover the device as a whole. The second outer cover can slide inside the first outer cover through a groove, which is convenient to move in conjunction with the air spring and helps to improve the dustproof efficiency of the dust cover.

[0019] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] like Figure 1-3 The tabletop car shock absorber shown includes an oil reservoir 1, a piston rod 3 is slidably connected inside the oil reservoir 1, a spring tray 2 is fixedly connected to the outside of the oil reservoir 1, a second connector 5 is fixedly connected to the top of the piston rod 3, a first connector 4 is fixedly connected to the bottom of the oil reservoir 1, and an air spring 20 is installed between the second connector 5 and the spring tray 2.
[0021] The bottom of the second connector 5 has a limiting groove 7, and a dust cover 8 is snapped into the inside of the limiting groove 7. The top of the dust cover 8 has a first mounting groove 9, and a protrusion 10 is provided inside the first mounting groove 9. A limiting post 11 is fixedly connected inside the protrusion 10, and a limiting frame 13 is slidably connected to the outside of the limiting post 11. A fixing plate 14 is fixedly connected to the end of the limiting frame 13 away from the protrusion 10. A circular groove 15 is provided inside the fixing plate 14, and a connecting post 16 is fixedly connected to the inner side wall of the fixing plate 14. A sliding shaft 17 is slidably connected inside the connecting post 16, and an operating hole 19 is provided inside the sliding shaft 17. A threaded post 18 is fixedly connected to the end of the sliding shaft 17. A threaded groove 6 is provided on the circumferential surface of the second connector 5, and the threaded post 18 is threadedly connected to the inside of the threaded groove 6. When the device is in use, the fixed plate 14 drives the limiting frame 13 to slide outside the limiting post 11, so that the connecting post 16 drives the threaded post 18 away from the second connecting head 5 through the sliding shaft 17. Then, the dust cover 8 is fitted into the limiting groove 7 at the bottom of the second connecting head 5. Then, the sliding shaft 17 is rotated by the operating hole 19, so that the threaded post 18 is threadedly connected to the threaded groove 6, thereby realizing the installation of the dust cover 8. Moreover, there is no need to disassemble the parts during the installation process, which helps to avoid the loss of parts.
[0022] Multiple protrusions 10 and limiting posts 11 are provided. Each limiting post 11 is fitted with a compression spring 12, and a limiting frame 13 is fitted on the outside of the compression spring 12. When the limiting frame 13 is fitted on the outside of the compression spring 12, it can compress the compression spring 12, so that the compression spring 12 generates a reaction force on the limiting frame 13, which makes it easy for the fixing plate 14 to always be located inside the first mounting groove 9.
[0023] The dust cover 8 includes a first outer cover 801, with a groove 802 inside the first outer cover 801. A second outer cover 803 is slidably connected inside the groove 802, and the bottom of the second outer cover 803 is in contact with the top of the spring tray 2. In use, the first outer cover 801 and the second outer cover 803 completely cover the device. The second outer cover 803 can slide within the first outer cover 801 via the groove 802, facilitating movement in conjunction with the air spring 20 and improving the dust cover 8's dust-proof efficiency.
[0024] The inner wall of the first outer cover 801 is provided with a protruding ring, which engages with the inside of the limiting groove 7. The protruding ring can be used to engage well with the limiting groove 7.
[0025] The connecting column 16 has a displacement groove inside, and the sliding shaft 17 is in contact with the inner wall of the displacement groove. The sliding shaft 17 can slide along the inner wall of the displacement groove, and can also rotate inside it.
[0026] The operating hole 19 is cross-shaped, and the position of the operating hole 19 corresponds to that of the circular groove 15. The cross-shaped operating hole 19 facilitates the rotation of the sliding shaft 17, thereby driving the threaded column 18 to connect with the threaded groove 6.
[0027] Working principle: When in use, the device is installed inside the vehicle using the first connector 4 and the second connector 5. During vehicle operation, the piston rod 3 slides inside the oil reservoir 1, and the air spring 25 helps to dampen the vehicle's vibration. When installing the dust cover 8, the fixing plate 14 drives the limiting bracket 13 to slide outside the limiting post 11, so that the connecting post 16 drives the threaded post 18 away from the second connector 5 through the sliding shaft 17. Then, the dust cover 8 is fitted into the limiting groove 7 at the bottom of the second connector 5. Next, the sliding shaft 17 is rotated using the operating hole 19, so that the threaded post 18 is threadedly connected to the threaded groove 6, thereby realizing the installation of the dust cover 8. The installation process does not require disassembling parts, which helps to avoid the loss of parts.
[0028] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
