Description

Technical Field

[0001] The utility model relates to the technical field of shifting mechanisms, and more particularly to a hard-wired shift lever assembly for a tricycle. Background Art

[0002] The hard-wired shift lever assembly of a tricycle is an important component of the tricycle transmission system. It allows the driver to change the gear of the tricycle by operating the shift lever, thereby controlling the speed and power output of the tricycle.

[0003] Existing rigid-wire shift lever assemblies for tricycles use a self-sensing method for gear adjustment. When the rigid-wire gear position changes, the shift lever's tilt angle changes, and the internal mechanical linkage latches adapt to the corresponding gear position. This adjustment method results in unclear shifting, which can easily affect shifting accuracy. Furthermore, the shift lever lacks an effective stop structure, which can affect usability. The existing lever is hollow and easily damaged, and the lever is easily affected by rocker arm deflection. In light of these issues, we propose a rigid-wire shift lever assembly for tricycles. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a hard-line shift lever assembly for a tricycle to solve the technical problems that the current hollow lever is easily damaged, the lever is eccentric relative to the rocker arm, and is easily affected.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a hard-wired shift lever assembly for a tricycle, comprising a shift lever body, an outer shell and an assembly piece, a bottom plate being fixed to the lower end of the outer shell, and a hard wire being provided on the rear side of the bottom plate, side grooves being provided on both sides of the outer shell, the assembly piece being installed in the side grooves, a handle being provided at the upper end of the shift lever body, a shaft sleeve being provided at the lower end of the shift lever body, and the shaft sleeve being rotatably installed in the outer shell by a rotating shaft, a linkage block being provided on the outer side of the shaft sleeve, and the linkage block being connected to the upper end of the hard wire by a hinge, and the shift lever body being installed on the outer shell.

[0006] When the utility model is used, the operator pulls the shift lever body by the handle to deflect the shift lever body, and the shift lever body completes the deflection through the shaft sleeve and the rotating shaft, and the gear shifting operation is completed by pulling the hard wire through the linkage block. The solid shift lever body structure design makes it difficult to weld and deform, thereby ensuring its service life. The bottom drag is used to complete the detachable assembly through the fixing bolts, which is convenient for later disassembly and replacement. When the shift lever body drives the bottom drag to deflect, the clamping column on the side of the bottom drag slides inside the clamping bar group. The clamping bar group has an empty groove corresponding to the gear position. The outer end of the clamping column is provided with a blocking rubber sleeve. When the clamping column moves inside the clamping bar group, the rubber sleeve structure improves the blocking feeling of the clamping column displacement, which is convenient for the operator to judge by hand feeling. When the clamping column enters the corresponding empty groove of the clamping bar group, the blocking feeling disappears, and the gear shifting operation is judged to be completed. The shaft sleeve and the rotating shaft are used as rotation support points, and the clamping column cooperates with the clamping bar group to realize the outer fulcrum of the lever, which reduces the difficulty of operation and is convenient for the operator to judge whether the gear shifting operation is completed by hand feeling.

[0007] Preferably, edge strips are distributed in an array on the outer side of the assembly piece, and a clamping strip group is fixed on the inner side of the assembly piece. The clamping strip group is designed to be arc-shaped, and the clamping strip group and the shaft sleeve are concentric circles.

[0008] Preferably, an array of slots are provided at the outer openings of the side grooves, and the side strips are snap-fitted and fixed in the corresponding slots.

[0009] Preferably, the shift lever body is designed in an L-shaped structure, and the shift lever body is adapted to the front opening of the housing.

[0010] Preferably, a bottom drag is installed on the lower side of the lower end of the shift lever body, and both ends of the bottom drag are provided with clamping columns, and the clamping columns are slidably inserted in the corresponding clamping strip group.

[0011] Preferably, both ends of the clamping column are provided with rubber sleeves, and empty slots are equidistantly provided in the clamping strip group, and the rubber sleeves are adapted to the empty slots.

[0012] Preferably, a fixing bolt is installed through the upper thread of the lower end of the shift lever body, and the lower end thread of the fixing bolt is installed on the bottom drag.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model designs a shift lever body. The operator pulls the shift lever body through the handle to deflect the shift lever body. The shift lever body completes the deflection through the shaft sleeve and the rotating shaft. The hard wire is pulled by the linkage block to complete the shifting operation. The solid shift lever body structure design makes it difficult to weld and deform, ensuring its service life. The detachable assembly is completed by the bottom drag and the fixing bolts, which is convenient for later disassembly and replacement.

[0015] 2. The utility model also designs an assembly piece. When the shift lever body drives the bottom drag to deflect, the card column on the side of the bottom drag slides inside the card strip group. There is an empty slot corresponding to the gear position in the card strip group. The outer end of the card column is provided with a blocking rubber sleeve. When the card column is displaced inside the card strip group, the blocking feeling of the card column displacement is improved by the rubber sleeve structure, which is convenient for the operator to judge by feel. When the card column enters the empty slot corresponding to the card strip group, the blocking feeling disappears, and the gear shifting operation is judged to be completed. The shaft sleeve and the rotating shaft are used as the rotation support points, and the outer fulcrum of the lever is realized by the card column and the card strip group, which reduces the difficulty of operation and makes it convenient for the operator to judge whether the gear shifting operation is completed by feel.

[0024] like Figures 2 to 6 As shown, the utility model relates to a hard-wired shift lever assembly for a tricycle, comprising a shift lever body 1, a housing 2 and an assembly piece 4. The shift lever body 1 is mounted on the housing 2. The shift lever body 1 is designed in an L-shaped structure, and the shift lever body 1 is adapted to the front opening of the housing 2. A bottom drag 5 is mounted on the lower side of the lower end of the shift lever body 1.

Both ends of the card column 501 are provided with a rubber sleeve.
