[0001] The present invention relates to the technical field of shock-absorbing bridges, and particularly to a shock-absorbing bridge for a four-wheel skateboard. Background Art

[0002] Skateboarding is one of the board sports. Athletes step on sliding equipment and perform various complex sliding, jumping, rotating, flipping and other difficult tricks on different terrains, grounds and specific facilities under the rhythm of music.

[0003] A skateboard mainly consists of a board surface and sandpaper, brackets (also known as skateboard bridges), shock-absorbing rubber, pulleys and bearings. After long-term use, the traditional four-wheel skateboard bridge will cause foot discomfort due to the vibration generated by the contact between the wheels and the ground.

[0004] Therefore, how to deal with the shock-absorbing bridge is a technical problem that needs to be solved by those skilled in the art at present. Summary of the Invention

[0005] The purpose of the present invention is to propose a shock-absorbing bridge for a four-wheel skateboard in view of the problems in the background art.

[0006] The technical solution of the present invention: A shock-absorbing bridge for a four-wheel skateboard, including a shock-absorbing bridge main body composed of a bridge component, a swing arm component, a fixing component, a shock absorber and a wheel group. The shock-absorbing bridge main body and the board body symmetrically together form a four-wheel skateboard structure. The bridge component includes a bridge. Kits are symmetrically arranged up and down in the middle of the bridge. A main bridge screw for connecting the swing arm component is penetrated between multiple kits. The swing arm component includes a bridge base installed on the main bridge screw. Swing arm bodies are symmetrically arranged on the left and right sides of the bridge base. A fixing component is arranged between the symmetric swing arm bodies. The fixing component includes a base fixing piece. A base is arranged above the base fixing piece. The base fixing piece and the base are assembled and fixed by multiple base screws. The shock absorber is connected to the base through a set screw.

[0007] Preferably, the kit includes a cylindrical PU and a gasket. The gasket is arranged on the end face of the cylindrical PU to enhance the stability of the connection of the main bridge screw.

[0008] Preferably, the wheel group includes two wheel bodies, and the two wheel bodies are respectively installed at both ends of the bridge.

[0009] Preferably, a wooden board is arranged between the base fixing piece and the base. The base fixing piece is installed at the bottom of the wooden board, and the base is arranged at the top of the wooden board.

[0010] Preferably, the output end of the shock absorber is connected to the symmetric swing arm bodies in the swing arm component through a mm lock.

[0011] Preferably, the base and the swing arm body are fixedly connected by a lock nut.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] 1. By providing the swing arm assembly and the shock absorber, when the swing arm assembly rotates upward, the shock absorber is stretched, thereby absorbing vibrations.

[0014] 2. By providing the swing arm assembly, the turning radius is changed and the driving stability is increased. For example, when the vehicle body is driving and the road surface is uneven, causing the wheels to be impacted, the swing arm assembly will rotate upward when absorbing vibrations. In this way, the turning radius of the vehicle body will become larger, the steering sensitivity will decrease, and the driving stability will increase. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] As Figure 2 shown, the four-wheel skateboard shock bridge proposed by the present invention includes a shock bridge main body composed of a bridge assembly 1, a swing arm assembly 2, a fixing assembly 3, a shock absorber 4 and a wheel set 5. The symmetrical shock bridge main body and the board body together form a four-wheel skateboard structure. The bridge assembly 1 includes a bridge 11. Kits are symmetrically arranged up and down in the middle of the bridge 11. A main bridge screw 14 for connecting the swing arm assembly 2 is arranged through the kits. The swing arm assembly 2 includes a bridge base 21 installed on the main bridge screw 14. Swing arm bodies 22 are symmetrically arranged on the left and right sides of the bridge base 21. A fixing assembly 3 is arranged between the symmetrical swing arm bodies 22. The fixing assembly 3 includes a base fixing member 31. A base 32 is arranged above the base fixing member 31. The base fixing member 31 and the base 32 are assembled and fixed by a plurality of base screws 33. The shock absorber 4 is connected to the base 32 by a set screw.

[0021] In this embodiment, the number of base screws 33 is set to be six to ten, and six are used in this embodiment.

[0022] Based on the working principle of the four-wheel skateboard shock-absorbing bridge in Embodiment 1: When the product is assembled and in use, when the wheel set 5 is stressed, it transfers the force to the bridge assembly 1. The bridge assembly 1 transfers the force to the bridge base 21 in the swing arm assembly 2 through the bridge main screw 14. The bridge base 21 is connected to the swing arm main body 22 through the swing arm screw. Then, as the bridge base 21 is stressed, the swing arm main body 22 is stressed synchronously and rotates upward. Then, it drives the fixing assembly 3 to move, and the movement of the fixing assembly 3 causes the shock absorber 4 to be stretched. Thus, the turning radius is changed and the driving stability is increased. For example, when the vehicle body is driving and the road surface is uneven, causing the wheel set 5 to be impacted, the swing arm assembly 2 will rotate upward when absorbing the vibration. In this way, the turning radius of the vehicle body will become larger, the steering sensitivity will decrease, and the driving stability will increase.

The gasket 13 is arranged on the end face of the cylindrical PU 12 to strengthen the stability of the connection of the bridge main screw 14. The wheel set 5 includes two wheel bodies, and the two wheel bodies are respectively installed at both ends of the bridge 11.

[0025] In this embodiment, a bridge main nut that is threadedly connected to the bridge main screw 14 is provided at the bottom of the gasket 13 in the bottom kit. Then, the installation and fixation of the bridge main screw 14 on the bridge assembly 1 are realized through the bridge main nut.

[0026] Embodiment 3

[0027] As Figure 1 shown, based on the above Embodiment 1 or 2, this embodiment further includes: A wooden board is provided between the base fixing member 31 and the base 32. The base fixing member 31 is installed at the bottom of the wooden board, and the base 32 is arranged on the top of the wooden board. The output end of the shock absorber 4 is connected to the symmetric swing arm main body 22 in the swing arm assembly 2 through 8mm counter-locking, and the base 32 and the symmetric swing arm main body 22 are fixedly connected through a counter-locking nut.

[0028] In this embodiment, the models of the shock absorber 4 are diverse, and SHR90A is used in this embodiment.
