Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a beach vehicle shifting device. Background Art

[0002] Beach buggies are also known as "all-terrain four-wheel off-road vehicles". Beach buggies are vehicles that can travel on any terrain and can travel freely on terrain that is difficult for ordinary vehicles to maneuver. The vehicle is simple and practical, and has good off-road performance. On soft sand, the wide tires of beach buggies increase the contact area with the ground to generate greater friction, and the unique tread pattern makes it difficult for the tires to spin and slip, making it easy to travel on sand. Beach buggies with good quality and excellent performance can not only travel on beaches; they can also easily overcome riverbeds, forest roads, streams, and even more severe deserts. Carrying people or transporting goods makes the functions of beach buggies fully utilized, and it can be called an all-round action tool.

[0003] As people's demand for ATVs grows, the requirements for driving comfort are also getting higher and higher. Usually, the gearboxes of ATVs on the market are set at the bottom of the frame, so the control lever connected to the gearbox can only be set at the bottom, resulting in the need to bend down to shift gears during operation, which is very inconvenient when switching gears, especially for operators with smaller bodies. It is very laborious to control the gear shift, and they need to bend over or stretch their bodies to operate. Utility Model Content

[0037] like Figures 1 to 5As shown, this embodiment proposes a beach buggy shifting device, including a steering column 1, a shell 2, a handle 3, and a cable 4. The shell 2 is sleeved on the steering column 1 through a bushing, and the shell 2 rotates relative to the bushing 11. The handle 3 is movably arranged on the shell 2, and the handle 3 can be used to drive the shell 2 to rotate. One end of the cable 3 is connected to the shell 2, and the other end of the cable 3 is connected to an external shifter. In addition, the bushing 11 is provided with a plurality of gear limit grooves 11 at intervals along its radial direction, and a clamping platform 31 is provided at one end of the handle 3 close to the shell 2. A through hole is provided on the shell 2, and the through hole can allow the clamping platform 31 to pass through and cooperate with each gear limit groove 11. In this way, by operating the handle 3, the handle 3 drives the shell 2 to rotate, and the shell 2 then drives the cable 4 to move. Since the other end of the cable 4 is connected to the external gear shifter, the gear switching can be realized. When the card platform 31 of the handle 3 is inserted into different gear limit grooves 11, the switching of different gears can be realized. By arranging the handle 3 on the steering column 1, the handle 3 is within reach and can be operated by stretching out the hand. Even for a smaller driver, it is very convenient and labor-saving to operate the gear change, and it also indirectly avoids the accidental risks caused by bending or stretching the body during driving.

[0038] In the present application, when in the initial position, the card platform 31 on the handle 3 is inserted into one of the gear limit slots 11; when the gear switch is required, the handle 3 is lifted upward to separate the handle 3 from the gear limit slot 11, so that the handle 3 can be rotated, and the handle 3 drives the shell 2 to rotate, and the shell 2 then pulls the cable 4 to move to achieve gear switching. When the card platform 31 of the handle 3 is inserted into different gear limit slots 11, different gear switches can be achieved, which is simple and convenient.

[0039] For further information, see Figure 1 As shown, the bushing 11 is also fixedly provided with a limit column 5, and the housing 2 is provided with a slideway opening 21, and the limit column 5 can pass through the slideway opening 21 and be fixedly installed on the bushing 11. In this way, by providing the limit column 5 and the slideway opening 21, the sliding stroke of the housing 2 can be limited, that is, the sliding stroke of the housing 2 moves from one end of the slideway opening 21 to the other end of the slideway opening 21.

[0040] For further information, see Figure 2 and Figure 3 As shown, the housing 2 is further provided with a support 6 and a pin 61, and the pin 61 can be used to install the handle 3 on the support 6. Specifically, the support 6 is provided with a positioning through hole, and the handle 3 is provided with a through hole, and the pin 61 is inserted into the positioning hole and the through hole. In this way, the handle 3 can be hinged on the support 6 through the cooperation of the pin 61, the positioning through hole, and the through hole.

[0041] For further information, see Figure 3 As shown, the pin shaft 61 is also sleeved with a torsion spring 7. By providing the torsion spring 7, the handle 3 can be elastically pushed to return to its original position, that is, the clamping platform 31 of the elastically pushed handle 3 is clamped into the gear limiting groove 11.

[0042] For further information, see Figure 2 As shown, the housing 2 is further provided with a connecting plate 21, and the connecting plate 21 is connected to the cable 4. Preferably, the housing 2 and the connecting plate 21 are integrally formed. Through the integral connection, the bonding strength between the connecting plate 21 and the housing 2 can be enhanced, the subsequent machining is reduced, and the processing cost is reduced. Of course, in this embodiment, the housing 2 can also be detachably connected to the connecting plate 22 by means of a buckle or the like, which is not the only limitation here.

[0043] For further information, see Figure 2 As shown, the shifting device further includes a bolt 22 and a nut 23, which can be used to fix the connection plate 21 with the cable 4. Specifically, a connection through hole is provided on the connection plate 21, and a locking ring 41 is provided on the cable 4. The bolt 22 can pass through the connection through hole and the locking ring 41 and be fastened with the nut 23. In this way, the connection plate 21 is fixedly connected with the cable 4 by the bolt 22 passing through the connection through hole and the locking ring 41 in sequence, and then being connected with the nut 23 by matching.

[0044] For further information, see Figure 3 As shown, the steering column 1 is also provided with a positioning plate 8, and a limiting hole 81 is provided on the positioning plate 8. By providing the positioning plate 8, it is possible to prevent the cable 4 from being wound around the steering column 1 as the housing 2 rotates during movement; by providing the limiting hole 81, on the one hand, the cable 4 can pass through the limiting hole 81 and connect with the connecting plate 22, and on the other hand, the cable 4 is limited to move in a specified direction.

[0045] Preferably, see Figure 3 As shown, the positioning plate 8 is provided with a limiting opening 82, which is connected to the limiting hole 81. By providing the limiting opening 82, the cable 4 can be easily slid into the limiting hole 81 through the limiting opening 82, thereby improving the installation efficiency.

[0046] Preferably, the spacing between the limiting openings 82 is smaller than the diameter of the cable 4. Thus, by setting the spacing between the limiting openings 82 to be smaller, the cable 4 can be restricted from sliding out of the limiting hole 81, so that the cable 4 moves in a specified direction.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
