Description

Technical Field

[0001] The utility model relates to the technical field of tricycles, and more specifically, to a high-low speed shifter for tricycles. Background Art

[0002] A tricycle is a vehicle with three wheels, usually consisting of a carriage, two rear wheels, and a steerable front wheel. Some electric tricycles are also equipped with a high-low speed shift switch, and the driver can operate this switch to switch the high-low speed mode of the vehicle.

[0003] The existing shifting structure of electric tricycles is relatively large and not flexible enough to use. Moreover, the hard-wired shifting of existing electric tricycles does not have a matching shift lever, making it inconvenient to operate. In view of this, we propose a high-low speed shifter for tricycles. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a high-low speed shifter for tricycles to solve the technical problem that the hard-wired shifting of current electric tricycles does not have a matching shift lever and is inconvenient to operate.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A high-low speed shifter for tricycles, including a side frame plate and an assembly mechanism. A cup cover is inserted into the rear opening of the side frame plate. The assembly mechanism is installed at the front end of the side frame plate, and a shifting mechanism is arranged inside the assembly mechanism. The assembly mechanism consists of a frame body and a bottom plate. The upper end of the frame body is embedded and installed on the side frame plate. The bottom plate is fixed to the lower side of the frame body, and an installation groove is opened at the outer end of the bottom plate. An internal mechanism is fixed inside the upper opening of the frame body.

[0006] When the utility model is in use, the operator sits on the seat and pulls the handle with the right hand to drive the shift lever to deflect. The shift lever turns through the rotating part to synchronously deflect the connecting piece. The connecting piece pulls the hard wire through the linkage head, and the other end of the hard wire drives the gearbox to complete the shifting operation. This device uses the shift lever structure of an airplane for shifting, with a small size, assembled at the corresponding fitting position of the tricycle, convenient to operate, high flexibility in use, reducing the shifting difficulty. When the shift lever deflects, the shift lever drives the limit frame to slide inside the internal frame. When the deflection distance increases, the collar slides on the surface of the shift lever. At the same time, the collar rotates in the adjustment groove through the side cylinder to adapt the inclination angle of the shift lever. When pushed to the corresponding gear, the inner end of the positioning post is inserted into the corresponding positioning hole to complete physical positioning and produce a sound for the operator to judge. This device facilitates the operator to judge different gears during the shifting process through limit and adaptability adjustment, reducing the operation difficulty of the device.

[0007] Preferably, the built-in mechanism consists of a built-in frame and a limiting mechanism, and sliding grooves are formed on both inner sides of the built-in frame.

[0008] Preferably, the limiting mechanism consists of a limiting frame and a collar. The limiting frame is located inside the built-in frame. An adjustment groove is formed inside the limiting frame, and a collar is rotatably installed in the adjustment groove.

[0009] Preferably, side cylinders are embedded on both sides of the collar, and positioning columns are elastically and slidably installed in the inner openings of the side cylinders through springs. The outer ends of the side cylinders are rotatably installed in the side openings of the limiting frame.

[0010] Preferably, the outer ends of the side cylinders pass through the side openings of the limiting frame and are slidably installed in the sliding grooves. The adjustment groove is designed in a scissor structure.

[0011] Preferably, the gear shifting mechanism consists of a wire sleeve, a linkage head, a connecting piece, and a shift lever. The connecting piece and the shift lever form an L shape, and the connection part is rotatably installed in the frame body through a rotating part. The linkage head is rotatably connected to the connecting piece.

[0012] Preferably, a handle is fixed to the upper end of the shift lever. The middle part of the shift lever is slidably inserted into the collar. Positioning holes are equidistantly formed in the middle of both sides of the shift lever, and the positioning columns are adapted to the positioning holes.

[0013] Preferably, a stud is fixed to the front end of the wire sleeve, and the stud is fixed in the installation groove through a nut. A rigid wire is arranged inside the wire sleeve, and the rigid wire is fixed to the linkage head.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By designing the gear shifting mechanism, when the operator sits on the seat and pulls the handle with the right hand to drive the shift lever to deflect, the shift lever turns through the rotating part to synchronously deflect the connecting piece. The connecting piece pulls the rigid wire through the linkage head, and the other end of the rigid wire drives the gearbox to complete the gear shifting operation. This device uses the shift lever structure of an airplane for gear shifting, which is small in size, assembled at the corresponding fitting position of the tricycle, convenient to operate, highly flexible in use, and reduces the difficulty of gear shifting.

[0016] 2. The present utility model also designs the built-in mechanism and the limiting mechanism. When the shift lever deflects, the shift lever drives the limiting frame to slide inside the built-in frame. When the deflection distance increases, the collar slides on the surface of the shift lever. At the same time, the collar rotates in the adjustment groove through the side cylinder, so that the collar adapts to the inclination angle of the shift lever. When pushed to the corresponding gear position, the inner end of the positioning column is inserted into the corresponding positioning hole to complete physical positioning and generate a sound for the operator to judge. Through limiting and adaptability adjustment, this device facilitates the operator to judge different gears during the gear shifting process and reduces the operation difficulty of the device.
