[0002] The golf cart realizes driving through the rolling of the wheels. When the golf cart bag encounters an uneven potholed road surface during driving, it will generate a large sense of shock, which not only has low comfort, but also easily causes damage to the golf cart itself or the items in the golf cart, greatly affecting the use experience.

[0003] At present, for golf carts on the market, in order to reduce the vibration during driving, a shock-absorbing mechanism is usually arranged on the frame for installing the wheels or between the wheels and the frame. Although this shock-absorbing mechanism can reduce the vibration during the driving of the golf cart, it will cause the volume of the golf cart to increase significantly, which is not convenient for storage. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a shock-absorbing wheel for a golf cart that can reduce the vibration during the driving of the golf cart without causing the volume of the golf cart to increase, making the golf cart convenient for storage.

[0005] The technical solution adopted by the utility model to solve the above technical problem is as follows: A shock-absorbing wheel for a golf cart includes a hub and a tire. The tire is located outside the hub and is installed on the hub. A bearing seat for connecting with the frame of the golf cart is arranged inside the hub. A cavity is formed between the hub and the bearing seat. n connectors and n springs are arranged in the cavity, where n is an integer greater than or equal to 3. The n connectors are evenly spaced along a circle. Both ends of each connector are respectively installed on the bearing seat and the hub, and the connector can rotate relative to the bearing seat and move in and out relative to the hub, or can rotate relative to the hub and move in and out relative to the bearing seat. n gaps are formed between the n connectors. The n springs are respectively located at the n gaps. The n springs are evenly spaced along a circle. The n connectors and the n springs correspond one by one. Among a corresponding connector and a spring, the connector and the spring are adjacent, and one end of the spring is fixed on the connector, and the other end of the spring is fixed on the bearing seat.

[0006] n moving chutes evenly spaced along a circle are arranged on the hub. The n connectors correspond to the n moving chutes one by one. One end of each connector is installed on the hub through a riveting part, and the riveting part is located in the corresponding moving chute, and the other end is installed on the bearing seat through a riveting part.

[0007] The bearing seat is provided with n movable sliding grooves evenly distributed at intervals along a circle. The n connecting pieces correspond to the n movable sliding grooves one by one. One end of each connecting piece is installed on the hub through a riveting piece, and the other end is installed on the bearing seat through a riveting piece. And the riveting piece is located in the corresponding movable sliding groove.

[0008] Compared with the prior art, the advantages of the present utility model are that a bearing seat for connecting with the frame of a golf cart is arranged inside the hub. A cavity is formed between the hub and the bearing seat. There are n connecting pieces and n springs arranged in the cavity, where n is an integer greater than or equal to 3. The n connecting pieces are evenly distributed at intervals along a circle. Both ends of each connecting piece are respectively installed on the bearing seat and the hub. And the connecting piece can rotate relative to the bearing seat and move in and out relative to the hub, or can rotate relative to the hub and move in and out relative to the bearing seat. n gaps are formed between the n connecting pieces. The n springs are respectively located at the n gaps. The n springs are evenly distributed at intervals along a circle. The n connecting pieces and the n springs correspond to each other one by one. In a corresponding connecting piece and a spring, the connecting piece and the spring are adjacent, and one end of the spring is fixed on the connecting piece, and the other end of the spring is fixed on the bearing seat. When the shock-absorbing wheel of the present utility model is installed on a golf cart, during the driving process of the golf cart, if the road surface is uneven and vibrations occur, at this time, the impact force generated by the vibrations is transmitted to the hub through the outer tire, and then transmitted to the n connecting pieces through the hub. Since the n connecting pieces can rotate relative to the bearing seat and move in and out relative to the hub, or can rotate relative to the hub and move in and out relative to the bearing seat, at this time, some of the n connecting pieces will compress the springs connected to them under the action of the impact force, and some will stretch the springs connected to them. The n springs buffer the impact force, thereby effectively reducing the impact force transmitted to the frame and achieving shock absorption. And because the bearing seat, the n connecting pieces and the n springs are all installed in the inner area of the outer tire, it will not additionally increase the volume of the wheel. Therefore, while reducing the vibrations during the driving process of the golf cart, the present utility model will not cause the volume of the golf cart to increase, making the golf cart convenient for storage.
