Description

Technical Field

[0001] This utility model relates to the field of shock absorber simulation exhibition technology, specifically a shock absorber simulation exhibition device. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of the spring after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride smoothness of the car. When driving over uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself will still have reciprocating motion. The shock absorber is used to suppress this spring bounce. Currently, it is not convenient for manufacturers selling shock absorbers to visually demonstrate their damping effect. Some manufacturers even take customers into the car to experience them. However, since the differences between different shock absorbers may not be significant, it is difficult to perceive the differences between them by physical sensation alone. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please refer to Figures 1-6. This utility model provides a shock absorber simulation exhibition device, including a first conveyor belt 1. The surface of the first conveyor belt 1 is provided with a vibration simulation structure. A pair of supports 2 are symmetrically installed at the bottom of the first conveyor belt 1. A vertical plate 4 and a second conveyor belt (3) are fixedly installed on one of the supports 2. A shock absorber body 5 is vertically arranged on the vertical plate 4. A groove 6 is vertically opened on the surface of the vertical plate 4. A rotating shaft 7 is slidably connected inside the groove 6. A wheel 8 is rotatably connected to one end of the rotating shaft 7. A display structure is provided at the other end of the rotating shaft 7. The end of the shock absorber body 5 is connected to the surface of the rotating shaft 7.

[0022] Please see Figure 1 In this embodiment, the vibration simulation structure can be driven to move synchronously by the first conveyor belt 1. At this time, the vibration simulation structure can move horizontally directly below the wheel 8 and generate rolling friction with the wheel 8, thereby driving the wheel 8 to rotate at one end of the shaft 7. During this process, the vibration simulation structure can also drive the wheel 8 to generate vibration in the vertical direction, thereby transmitting the vibration to the shock absorber body 5 through the shaft 7 to drive the shock absorber body 5 to work. The shock absorber body 5 can simultaneously dampen the shaft 7 and the wheel 8. Finally, the shaft 7 after damping can be displayed on the surface of the second conveyor belt 3 through the display structure for customers to observe.

[0023] The vibration simulation structure includes a T-shaped track 9, a T-shaped slot 10, a splicing plate 11, and an arc-shaped protrusion 12. The arc-shaped protrusion 12 is fixedly connected to the top of the splicing plate 11. Several T-shaped tracks 9 are fixedly installed at equal intervals on the surface of the first conveyor belt 1. The T-shaped slot 10 is set at the bottom of the splicing plate 11. Each splicing plate 11 is slidably connected to the surface of the T-shaped track 9 through the T-shaped slot 10, and the sides of two adjacent splicing plates 11 are in contact with each other. The bottom of the wheel 8 is in contact with the surface of the splicing plate 11.

[0024] Please refer to Figure 2. Initially, the wheel 8 is located on top of the two splicing plates 11, and the wheel 8 is not in contact with the arc-shaped protrusion 12. When the first conveyor belt 1 starts, the splicing plate 11 will move horizontally below the wheel 8, thereby causing the arc-shaped protrusion 12 to contact the wheel 8 and lift the wheel 8. When the arc-shaped protrusion 12 moves horizontally to separate from the wheel 8, the wheel 8 will fall back onto the surface of the rear splicing plate 11 under the action of gravity. Repeating the above process can simulate the bumpy road conditions that cause the wheel 8 to vibrate, thereby simulating the working process of the shock absorber body 5.

[0025] It should be noted that the splicing plate 11 is installed on the belt of the first conveyor belt 1 via the T-shaped rail 9 and the T-shaped slot 10. This means that the splicing plate 11 can be removed from the surface of the first conveyor belt 1 to replace the arc protrusions 12 of different heights, thereby simulating different road conditions. Alternatively, the arc protrusions 12 of different heights can be installed alternately to simulate more realistic road conditions.

[0026] The display structure includes a swing arm 13, an end cap 14, a sleeve 15, a piece of chalk 16, and a groove 17. One end of the swing arm 13 is rotatably connected to one end of the rotating shaft 7. The sleeve 15 passes through and is fixed to the other end of the swing arm 13. The end cap 14 is threaded to the surface of the sleeve 15. The groove 17 is provided on the inner wall of the end cap 14. One end of the chalk 16 passes through the sleeve 15 and is inserted into the inside of the groove 17. The other end of the chalk 16 abuts against the surface of the second conveyor belt 3.

[0027] Please refer to Figures 1 and 5. When the shock absorber body 5 dampens the wheel 8, it acts directly on the axle 7. Therefore, the axle 7 is also damped at this time. In this embodiment, when the axle 7 vibrates vertically, it can drive the chalk 16 to vibrate synchronously through the swing arm 13, sleeve 15 and end cap 14. Then the second conveyor belt 3 is started. Since the chalk 16 is fixed in the horizontal position, when the belt of the second conveyor belt 3 moves, the chalk 16 can draw the path of the vertical vibration of the axle 7 on the surface of the belt, so that the customer can intuitively observe the damping of the wheel 8 by the shock absorber body 5.

[0028] It should be noted that after replacing the shock absorber body 5, rotating the swing arm 13 at one end of the rotating shaft 7 can cause the other end of the swing arm 13 to drive the chalk 16 to revolve. This allows the chalk 16 to redraw the motion trajectory of the replaced shock absorber body 5 on the wheel 8 in another area of ​​the second conveyor belt 3, so as to facilitate the comparison and observation of different shock absorber bodies 5. Furthermore, if the chalk 16 cannot contact the surface of the second conveyor belt 3 after a period of use, in this embodiment, the end cap 14 can be rotated to make the end cap 14 move horizontally on the surface of the sleeve 15, thereby allowing the end cap 14 to drive the end of the chalk 16 to continuously approach the belt of the second conveyor belt 3.

[0029] It should be understood that the method of drawing the movement trajectory of the wheel 8 with chalk 16 in this embodiment is only a rough reference and is only used for demonstration purposes so that customers can observe the damping effect of different shock absorber bodies 5. It is not used as a precise instrument for measuring the damping effect of the shock absorber body 5.

[0030] A limiting sleeve 18 is vertically fixed to the surface of the rotating shaft 7, and the bottom of the shock absorber body 5 is inserted into the inside of the limiting sleeve 18.

[0031] Please refer to Figures 3 and 4. The connection between the limiting sleeve 18 and the shock absorber body 5 can limit the rotation shaft 7 to prevent relative rotation between the rotation shaft 7 and the vertical plate 4 from affecting the position of the swing arm 13.

[0032] It should be noted that, since the bottom structures of different types of shock absorber bodies 5 are different, the bottom end of the shock absorber body 5 is first wrapped by the limiting sleeve 18, and then different clamps are set inside the limiting sleeve 18. The purpose is to achieve the connection between the bottom end of the shock absorber body 5 and the rotating shaft 7. In this embodiment, the bottom end of the shock absorber body 5 is an annular joint, and a crossbar is set inside the limiting sleeve 18. After the annular joint extends into the limiting sleeve 18, it is connected to the crossbar by horizontal movement, so as to achieve the connection between the shock absorber body 5 and the rotating shaft 7.

[0033] A fisheye connector 19 is fixedly connected to the top of the shock absorber body 5. An electric guide rail 20 is vertically fixedly installed on the surface of the upright plate 4. A support seat 21 is fixedly installed on the slider surface of the electric guide rail 20. A connecting rod 22 is slidably connected to the surface of the support seat 21. One end of the connecting rod 22 extends into the fisheye connector 19. A limit plate 23 is concentrically fixedly connected to one end of the connecting rod 22. The surface of the limit plate 23 is in contact with the surface of the support seat 21.

[0034] Please refer to Figures 1, 4, and 6. By pulling the connecting rod 22 laterally, it can be separated from the inside of the fisheye joint 19. Then, the shock absorber body 5 can be moved laterally so that the annular joint at its bottom end is detached from the surface of the crossbar, allowing the shock absorber body 5 to be replaced. After replacement, first connect the bottom annular joint to the rotating shaft 7, and then adjust the vertical height of the connecting rod 22 through the electric guide rail 20 so that the connecting rod 22 can adapt to the fisheye joint 19 at the top of the new shock absorber body 5. The limiting plate 23 is to prevent the connecting rod 22 from falling out of the fisheye joint 19 during vibration.

[0035] It should be noted that there is static friction between the connecting rod 22, the fisheye joint 19, and the support 21, which can further prevent the connecting rod 22 from falling out of the fisheye joint 19 during vibration. Moreover, when demonstrating the shock absorption effect, it is not necessary to start the first conveyor belt 1 for a long time; simply drawing a section of the movement path of the wheel 8 is sufficient. Therefore, the connecting rod 22 will not separate from the fisheye joint 19 under the drive of vibration.

[0036] A pair of limiting rings 24 are fixedly installed on the surface of the rotating shaft 7. The vertical distance between the two limiting rings 24 is equal to the thickness of the vertical plate 4, and the surfaces of the two limiting rings 24 are in contact with the surface of the vertical plate 4.

[0037] Please refer to Figure 3. The limiting ring 24 is set to restrict the rotating shaft 7 within the slide groove 6, thereby restricting the position of the wheel 8 and the chalk 16, and also restricting the position of the shock absorber body 5.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that...

[0039] For those familiar with this invention, it will be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this invention, the scope of which is defined by the appended claims and their equivalents.
