Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a rubber shock-absorbing front fork for scooters. Background Technology

[0002] A scooter is a vehicle that combines multiple functions such as short-distance transportation and leisure entertainment. Its main features include small size, light weight, flexibility, environmental protection and energy saving. To improve the comfort of riding a scooter, shock absorption devices are usually installed near the front fork of the scooter frame.

[0003] In the current technology, the shock absorption device of scooters is usually a spring structure or hydraulic shock absorption. Traditional spring shock absorption is not comfortable, and abnormal noise will occur over time. In addition, the spring will age and lose its elasticity, affecting the shock absorption effect. Hydraulic shock absorption is quite expensive. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a scooter rubber shock-absorbing front fork that features good shock absorption, low noise, reliable connection, and long service life.

[0005] This utility model is achieved through the following technical solution: a scooter rubber shock-absorbing front fork, including a front fork assembly and two sets of rubber shock-absorbing assemblies. The front fork assembly includes a vertical rod and a shock-absorbing connecting bracket. The shock-absorbing connecting bracket is U-shaped and has two support arms. The two sets of rubber shock-absorbing assemblies are symmetrically connected to the ends of the two support arms.

[0006] Furthermore, the shock-absorbing connecting bracket is an integral stamped part, and the bracket arm is stamped with reinforcing ribs to improve strength.

[0007] To improve shock absorption and reduce noise, thereby enhancing the riding comfort of the scooter, the rubber shock absorption assembly includes a shock absorption block seat, a rubber shock absorption block, a limiting connecting plate, and a transition connecting plate. The shock absorption block seat and the rubber shock absorption block are disposed on the outer side of the support arm, while the limiting connecting plate and the transition connecting plate are sequentially disposed on the inner side of the support arm. The shock absorption block seat has a shock absorption block cavity. The rubber shock absorption block consists of an outer shell, a shock absorption part, and a connecting shaft part, arranged sequentially from the outer circle to the center. The rubber shock absorption block is disposed within the shock absorption block cavity of the shock absorption block seat through the outer shell part. The end of the support arm, the limiting connecting plate, and the transition connecting plate are respectively provided with holes that match the connecting shaft part. The connecting shaft part passes through the end of the support arm, the limiting connecting plate, and the transition connecting plate in sequence and is then locked by washers and nuts.

[0008] Furthermore, the outer shell and connecting shaft of the rubber shock absorber are made of metal, the shock absorber is made of rubber, and the connecting shaft is threaded.

[0009] To improve connection reliability, the outer shell of the rubber damping block is interference-fitted with the damping block cavity of the damping block seat.

[0010] To improve the torsional resistance of the rubber damping block and enhance the positioning accuracy and convenience of installation, the damping block cavity has a positioning post at its center, and the rubber damping block has a positioning countersunk hole along its axis. The rubber damping block is fitted onto the positioning post of the damping block through the positioning countersunk hole.

[0011] To prevent abnormal wear caused by relative rotation of adjacent connecting parts during use, and to improve service life while reducing noise, a bushing is provided between the limiting connecting plate and the transition connecting plate. The bushing extends towards the transition connecting plate with a positioning boss whose outer diameter matches a hole on the transition connecting plate. A spacer is provided between the rubber damping block and the support arm of the damping connecting bracket.

[0012] Preferably, the bushing is made of nylon and the spacer is made of Q235B. However, bushings and spacers made of other materials may also be selected depending on the actual situation.

[0013] In order to limit the connecting shaft of the rubber shock absorber and strengthen the support of the shock absorber connecting bracket to improve the overall strength, the shape of the limiting connecting plate matches the inner groove of the bracket arm of the shock absorber connecting bracket. The limiting connecting plate is set in the inner groove of the bracket arm of the shock absorber connecting bracket. One end of the limiting connecting plate is sleeved on the connecting shaft of the rubber shock absorber, and the other end is fixedly connected to the bracket arm of the shock absorber connecting bracket.

[0014] In order to balance the unilateral rotational force on the rubber damping block, further improve the damping effect and service life, and improve the connection reliability, the end of the damping block seat away from the damping block cavity has a connecting boss. One end of the transition connecting plate is sleeved on the connecting shaft of the rubber damping block, and the other end is fixedly connected to the connecting boss.

[0015] To improve connection reliability and prevent relative rotation between the connecting shaft and the shock-absorbing connecting bracket, the limiting connecting plate, and the transition connecting plate, it is preferable that the connecting shaft of the rubber shock absorber is in the shape of a flat wire.

[0016] The beneficial effects of this utility model are as follows: This scooter rubber shock-absorbing front fork improves the shock absorption effect and reduces noise by designing a rubber shock-absorbing component with a rubber layer on the scooter frame front fork, thereby improving the riding comfort of the scooter; by designing connecting parts such as limiting connecting plates and transition connecting plates that cooperate with the rubber shock-absorbing component, the torsional resistance of the rubber shock-absorbing block is improved, further enhancing the shock absorption effect and service life; by designing parts such as bushings and spacers, the connection reliability is further improved, and the service life is extended; in addition, this scooter rubber shock-absorbing front fork has a compact structure.
