[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0025] like Figure 1-6The spring 3 is sleeved on the connecting post 2, and the lower end of the connecting post 2 is connected to the base 4. The spring 3 elastically abuts between the mounting plate 1 and the base 4, and the elastic protective member 5 is fixed to the lower end of the mounting plate 1, and the base 4 can abut the elastic protective member 5 upward. After the spring 3 is sleeved into the connecting post 2, the elastic expansion structure of the spring 3 passes through the mounting hole 101 upward and then bounces off, preventing the connecting post 2 from escaping from the mounting hole 101 when sliding downward. When the remote control car is driving normally, the bumps of the road are transmitted to the chassis of the remote control car, and then transmitted to the spring 3. Under the elastic action of the spring 3, the remote control car Filtering the vibration of bumpy roads can not only protect the stability of core components such as circuit boards and wires in the remote control car, but also simulate real driving conditions, adding a lot of fun to players; in the process of continuous compression and rebound of spring 3, if the road is bumpy, or the remote control car jumps from a high place, the spring 3 is extremely compressed, and the shock absorber will bottom out. At this time, the elastic protective part 5 abuts against the base 4 before the shock absorber bottoms out, and the deformation of the elastic protective part 5 provides a buffer for the base 4 to prevent the impact force of the base 4 from forming a collision when the shock absorber bottoms out, causing impact on core components such as circuit boards and wires in the remote control car, and also avoiding the reaction force of the large impact force when the shock absorber bottoms out directly bouncing the remote control car, thereby causing the remote control car to overturn; the elastic protective part 5 used in this device is made of metal, which has deformability and a certain rigidity, thereby avoiding the occurrence of shock absorber bottoming out.
[0026] In the above embodiment, there are two mounting holes 101 and two connecting columns 2, and the two connecting columns 2 are slidably connected to the two mounting holes 101 respectively. The lower ends of the two connecting columns 2 are respectively connected to the base 4, and the elastic protective member 5 is located between the two connecting columns 2. The two connecting columns 2 are sufficiently stable with the base 4, and can also provide better guidance and auxiliary force-bearing functions, preventing the deformation of a single connecting column 2 when the base 4 is subjected to lateral force, resulting in its sliding obstruction in the mounting hole 101, thereby affecting the shock absorption effect and the service life of the connecting column 2. The outer diameter of the upper end surface of the elastic expansion structure is less than or equal to the aperture of the mounting hole 101, ensuring that the elastic expansion structure can smoothly pass through the mounting hole 101, and the outer diameter of the middle part of the elastic expansion structure is greater than the aperture of the mounting hole 101, ensuring that the elastic expansion structure can expand and press against the upper end surface of the mounting plate 1 after shrinking through the mounting hole 101. The elastic support structure includes a plurality of support plates 6 arranged in a circumferential array on the upper end surface of the connecting column 2, the outer side of the support plate 6 is an arc surface 601, and the upper and lower ends of the arc surface 601 are respectively an upper arc edge and a lower arc edge. The outer diameter of the circle where the upper arc edge is located is less than or equal to the aperture of the mounting hole 101, and the outer diameter of the circle where the lower arc edge is located is larger than the aperture of the mounting hole 101. There is a horizontal support surface 602 between the lower arc edge and the support plate 6, and the support surface 602 can be abutted against the mounting plate 1 up and down; when the elastic support structure passes through the mounting hole 101 upward, the side of the mounting hole 101 is slidably connected to the arc surface 601, and at this time the support plate 6 yields and deforms toward the middle of the elastic support structure, allowing the circle where the lower arc edge is located to shrink and pass through the mounting hole 101 smoothly, and after passing through the mounting hole 101, the support plate 6 rebounds to realize the limiting function.
[0027] The device also includes a gasket 7, the aperture of which is consistent with the mounting hole 101, and the gasket 7 is sleeved on the connecting column 2, and the gasket 7 is located between the supporting surface 602 and the mounting plate 1; the gasket 7 can raise the elastic support structure, thereby shortening the distance between the base 4 and the mounting plate 1, and at the same time compressing the spring 3 to a certain extent to change the shock absorption effect; after the spring 3 is preloaded and compressed by the gasket 7, the base 4 is closer to the elastic protective member 5, and at the same time, under the reaction force of the spring 3, the resistance of the spring 3 is stronger, and it is less likely to bottom out under the impact of road bumps and the inertia of the remote control car's own weight, thereby avoiding excessive up and down shaking of the remote control car during driving.
[0028] In the above embodiment, the elastic protective member 5 includes a first U-shaped rod 501, a second U-shaped rod 502 and an arc-shaped rod 503. The two ends of the first U-shaped rod 501 and the second U-shaped rod 502 are respectively connected by two arc-shaped rods 503. There is an angle of 25-35° between the first U-shaped rod 501 and the second U-shaped rod 502. The first U-shaped rod 501 is fixed to the lower end of the mounting plate 1, and the base 4 can abut the second U-shaped rod 502 upward; in actual application, the angle between the first U-shaped rod 501 and the second U-shaped rod 502 is 30°. After the second U-shaped rod 502 abuts the base 4, the sliding distance of the second U-shaped rod 502 at the upper end of the base 4 is short, which will not affect the normal use of the connecting column 2. The mounting plate 1 is provided with three clips 10 at the lower end, and the three clips 10 are distributed in a triangular position. The first U-shaped rod 501 can be embedded in the three clips 10 at the same time; the clips 10 can cover three-quarters of the circumference of the first U-shaped rod 501, which not only reserves a quarter of the space for embedding, but also ensures that the first U-shaped rod 501 can be firmly locked after being embedded in the clips 10 and is not easy to fall off.
[0029] The base 4 is provided with a raised platform 12 at its upper end, which abuts against the second U-shaped rod 502. This increases the thickness of the abutment area and prevents the elastic protective member 5 from repeatedly abutting against the base 4 and causing permanent deformation. The connecting post 2 is provided with a threaded post 8 at its lower end. The base 4 has a through hole through which the threaded post 8 passes. A nut 9 is threadedly connected to the threaded post 8, with the base 4 positioned between the connecting post 2 and the nut 9. The nut 9 secures the base 4, similar to the quick-release mechanism of the buckle 10. Both facilitate component assembly, making assembly of the remote-controlled car easier and more enjoyable for players. The base 4 is provided with a symmetrical clamping plate 13 at its lower end, which has a hinge hole 1301 therein for convenient attachment of the remote-controlled car's wheels. A limit plate 11 is provided at the upper end of the mounting plate 1, and the elastic support structure can abut against the limit plate 11 upward to prevent the elastic protective member 5 from being deformed too much under the action of a large external force, and provide auxiliary support by abutting against the limit plate 11 by the elastic support structure; in actual application, the limit plate 11 is the shell of the remote control car.
[0030] Description of the working method of this utility model:
[0031] The first U-shaped rod 501 of the elastic protective member 5 is simultaneously embedded in the three buckles 10 at the lower end of the mounting plate 1, and the two springs 3 are respectively inserted into the two connecting columns 2, and then the elastic expansion structures at the upper ends of the two connecting columns 2 are respectively passed through the two mounting holes 101, and the two through holes on the base 4 are respectively inserted into the threaded columns 8, and the two nuts 9 are used to lock and press the base 4 against the lower ends of the connecting columns 2; according to the different scenarios adapted by different remote control cars, appropriate gaskets 7 are inserted into the elastic expansion structure. For example, for off-road remote control cars, which face a bumpy road, three gaskets 7 can be inserted to shorten the distance between the raising platform 12 and the second U-shaped rod 502, while providing pre-tensioning for the spring 3. The load makes the shock absorber system of the remote control car stiffer when it travels on bumpy roads, preventing the remote control car from shaking too much and easily turning over; when the remote control car returns to the ground after passing a high place, the remote control car's own gravity and inertia are transmitted to the spring 3 through the mounting plate 1, compressing the spring 3 and then releasing it. Since the spring 3 has been preloaded, the spring 3 has a certain ability to resist compression deformation, which reduces the possibility of the shock absorber bottoming out, making the body of the remote control car more stable. Moreover, under the protection of the elastic protective member 5, the shock absorber provides a relatively linear supporting force from small to large, and there will be no rapid bottoming out rebound that causes the remote control car to bounce up, thereby reducing the possibility of the remote control car turning over and also reducing the frequency of players picking up the remote control car.
[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
