Description

Handle switch with gap control function

Technical Field

The invention belongs to the technical field of motorcycle handlebar switches, and particularly relates to a handlebar switch with a gap control function.

Background

Due to the characteristics of motorcycle driving modes, functional switches for realizing vehicle control are usually designed and installed on a steering handle so as to facilitate the operation of a driver. The existing motorcycle handle switch is divided into an upper shell 1 and a lower shell 2 as shown in figures 1-3, wherein the opposite surfaces of the upper shell 1 and the lower shell 2 are provided with arc-shaped grooves, and the arc-shaped grooves and the lower shell are folded to form an assembly hole for a direction handle to pass through. During assembly, the upper shell 1 and the lower shell 2 are respectively buckled on the direction handle pipe and are tightly embraced, and then the upper shell and the lower shell are connected through the fastening bolt 4 and simultaneously the direction handle pipe is tightly embraced. The direction is really held tightly by the direction is realized by two partition plates 5 with semicircular grooves which are arranged inside the shell and are perpendicular to the direction and respectively fix the central axis of the direction handle tube on the upper shell and the lower shell, wherein the partition plates 5 of the lower shell 2 divide the lower shell 2 into an inner cavity and an outer cavity, the cavity on one side of the tail end of the handle is used for clamping a handle rubber sleeve, the cavity on the other side is used for placing a circuit board, a wire harness and the like of a switch, the circuit board and the wire harness are covered by a concave cover plate 8 which is adaptive to the direction and is used for covering the circuit board, the wire harness and the direction handle tube are separated by the cover plate 8 and the partition plates 5. When the upper and lower shells are folded, the upper and lower partition plates are also folded, and the two partition plates hold the direction handle pipe tightly through the opposite grooves. In order to better prevent the handlebar switch from rotating on the steering handle pipe after being installed, a positioning pin 3 used for positioning the handlebar switch and preventing the handlebar switch from rotating is further arranged on the arc-shaped concave surface of the lower shell of the handlebar switch, a corresponding positioning hole is formed in the steering handle pipe, the positioning pin 3 enters the positioning hole during assembly, and after the upper shell 1 and the lower shell 2 are locked with the steering handle pipe through a fastening bolt 4, the handlebar switch cannot rotate due to the positioning effect of the positioning pin.

In actual design, if the round hole formed by folding the partition plate is smaller than the direction handle pipe, although the handle switch and the direction handle pipe can be tightly held after the upper shell and the lower shell are fastened through the bolts, and the positioning pin is used for assisting, the handle switch can be well prevented from rotating, but a gap exists between the upper shell and the lower shell of the handle switch. The appearance of the gap influences the appearance, and on the other hand, dust and water possibly enter the handle switch through the gap to cause circuit short circuit and other adverse effects. If the round hole formed by folding the partition board is larger than the direction handle pipe, the upper shell and the lower shell can not hold the direction handle pipe tightly, namely the handle switch can rotate, although the gap between the upper shell and the lower shell is not formed after folding. Although the positioning pin is provided, if the positioning pin is slightly smaller than the positioning hole, namely the positioning pin and the positioning hole are in clearance fit, the clearance between the positioning pin and the positioning hole provides a space for the rotation of the handle switch. Under the condition, if the positioning pin is in interference fit with the positioning hole, the raised positioning pin can tightly abut against the direction handle pipe in the assembling process, so that the upper shell and the lower shell are difficult to be really pressed when the handle switch is installed, and a larger gap still exists; if the upper and lower shells are forcibly pressed, the structure of the handle switch may be damaged. It can be seen from the above analysis that the existing handle switch can not achieve the optimal effect on preventing rotation and controlling the gap between the upper and lower shells, and the two problems of preventing rotation and controlling the gap are difficult to be considered.
