[0002] Traditional gear levers and the tubes below them are fixed by traditional connection methods, such as bolts or rivets. At the same time, existing gear levers are often made of non-metallic materials. This has the advantage of being skin-friendly and easy to grip, but it also has high wear and tear and requires frequent replacement. This makes the traditional connection method cumbersome and not quick enough. In addition, slight wobbling between the gear lever and the tubes can also affect the shifting experience.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-7 A beach buggy shifting mechanism includes an adjusting pipe 1, a gear lever 2, and a connecting unit, wherein the adjusting pipe 1 is connected to the engine, that is, the engine is in different gears by adjusting the position of the adjusting pipe 1.

[0024] Meanwhile, the gear lever 2 has a hollow structure, and is air-sleeved outside the regulating tube 1. It can slide along the axial direction of the regulating tube 1 and is fixed on the regulating tube 1. Specifically, the gear lever 2 and the regulating tube 1 are quickly connected by a connecting unit.

[0025] In this embodiment, two sets of connecting units are provided and symmetrically arranged on both sides of the regulating tube 1. The connecting unit includes a housing 4 and a locking block 7. The housing 4 can pass through the connecting hole 5 of the regulating tube 1 and be connected therein. The outer side of the housing 4 can be threadedly fixed to the connecting hole 5 to realize the quick installation of the connecting unit in the regulating tube 1.

[0026] Meanwhile, the locking block 7 is slidably disposed within the housing 4. A first spring 6 is provided between the locking block 7 and the housing 4. Under normal static conditions, the elastic force of the first spring 6 pushes the locking block 7 to protrude outward. Furthermore, the locking block 7 is designed to include two parts: an arc-shaped protrusion 8 near the outer end and a locking hole for embedding into the side wall of the gear lever 2, and a cylindrical sliding part 9 that cooperates with the housing 4. The arc-shaped protrusion 8 is used to engage with the locking hole of the gear lever 2, thereby fixing the position of the gear lever 2, and the cylindrical sliding part 9 is used to slide within the housing 4.

[0027] The gear lever 2 is provided with a first groove 11 that matches the locking block 7. When the gear lever 2 moves downward, under the action of the arc-shaped protrusion 8, the gear lever 2 can drive the protrusion 8 to overcome the first spring 6 and move into the housing 4 until the gear lever 2 continues to move, thereby locking the locking block 7 into the first groove 11 of the gear lever 2, thus fixing the gear lever 2.

[0028] In further optimization, to address the issue of the locking block 7 wobbling when connected to the gear lever 2, a fixing strip 10 is provided at the connection between the sliding part 9 and the protrusion 8. The fixing strip 10 is embedded in the groove 11 at the front end of the sliding part 9.

[0029] Meanwhile, the gear lever 2 is equipped with a first placement groove 12 matching the locking block 7. A second placement groove 13 is provided on one side of the first placement groove 12. The second placement groove 13 is used to cooperate with the fixing strip 10. During the movement of the gear lever 2, the inner wall of the gear lever 2 first moves the locking block 7 into the adjusting tube 1 until it is flush. When the first groove 11 approaches the first placement groove 12, the locking block 7 and the fixing strip 10 quickly enter the groove 11 of the gear lever 2 under the action of the first spring 6 to form a lock.

[0030] Furthermore, the fixing strips 10 are all made of flexible rubber material. Therefore, under the compression of the first spring 6, they can fill the gap between the locking block 7 and the gear lever 2 to achieve a stable connection between the gear lever 2 and the adjusting tube 1, preventing shaking. When the gear lever 2 is pulled out, due to the strong friction between the fixing strips 10 and the gear lever 2, it is difficult to pull out the gear lever 2 to achieve a strong connection.

[0031] When the gear shifting mechanism is installed on the vehicle body 14, a shift plate 15 is fixed on the vehicle body 14. The surface of the shift plate 15 has multiple gear slots 16 corresponding to different gear positions. The end of the adjusting tube 1 is connected to the vehicle body 14 via a torsion spring 18. The restoring force of the torsion spring 18 causes the adjusting tube 1 to automatically return to its initial position in the gear slot 16 when no external force is applied. Each gear slot 16 on the shift plate 15 is accompanied by a gear position indicator 17, and the corresponding position on the gear lever 2 is also marked with the same indicator. In this embodiment, the gear position indicator 17 is "F", "N", and "R", facilitating quick gear selection for the user. During operation, the user grips the gear lever 2 and applies a lateral force. The gear lever 2 drives the adjusting tube 1 to move against the elastic force of the torsion spring 18 to the target gear slot 16, thus changing the gear position.

[0032] A through hole is provided on the gear lever 2. The through hole is normally blocked by a rubber sealing block 19. After the sealing block 19 is removed, a magnet is inserted into it. A corresponding metal piece can be provided on the inner side of the locking block 7. The locking block 7 moves into the adjusting tube 1 to unlock the gear lever 2, thereby removing it.

[0033] At this time, the locking block 7 is squeezed by the inner wall of the gear lever 2, and the sliding part 9 compresses the first spring 6 and retracts inward; when the gear lever 2 moves into place, the protrusion 8 of the locking block 7 pops out under the action of the spring and is embedded in the locking hole of the gear lever 2 to complete the gear shifting lock.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
