Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle brake devices, in particular to a brake power-off switch housing structure. Background Art

[0002] Electric vehicles are currently a common means of transportation. Electric vehicles generally use hand brakes. Among the brake components, the power-off switch is the most important component. It is installed on the bracket of the handle. The bracket is provided with a mounting hole. The power-off switch is fixed after passing through the mounting hole. The traditional housing includes a block body for accommodating the switch at the front section and a wire rod for passing the brake line at the rear section. The fixing method is to tighten the locking sleeve on the wire rod with a thread. Since the locking sleeve needs to be inserted from one end of the brake line, the operation is difficult. For this reason, a snap-on opening fixing piece is designed. The inner wall of the opening fixing piece is provided with a row of snap teeth. Due to the opening design and the use of elastic parts, the opening can be expanded, and the wire can be directly passed through, or even directly buckled on the wire rod, which can avoid being inserted from one end of the brake line, simplifying the operation. Figure 1 As shown, the existing conductor rod cannot cooperate with it, and a shell that cooperates with it is urgently needed. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a brake power-off switch housing structure, which can be fixed in cooperation with an opening fixing piece.

[0004] The technical solution is as follows: a brake power-off switch housing structure, which includes a front block body for accommodating the switch and a rear conductor rod for passing the brake line, characterized in that a row of slots arranged at intervals are provided on the conductor rod.

[0005] It is further characterized in that the clamping slot is arranged at the top of the conductor rod, and the bottom of the conductor rod is provided with a notch for clamping the opening fixing piece;

[0006] A transition disc is arranged between the conductor rod and the block body.

[0007] After adopting the utility model, the traditional external thread is cancelled, and a slot is set instead, which cooperates with the teeth on the opening fixing piece to ensure axial stability. In addition, after the opening fixing piece is buckled, radial falling off and free rotation will not occur, so it can cooperate with the opening fixing piece to achieve fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the structure of the existing opening fixing part;

[0009] Figure 2 It is a schematic diagram of the structure of the utility model;

[0010] Figure 3 It is a schematic diagram of the opening fixing piece used in conjunction with the utility model. DETAILED DESCRIPTION

[0011] See Figure 2 As shown, a brake power-off switch housing structure includes a block body 1 for accommodating the switch at the front section and a conductor rod 2 for passing the brake line at the rear section. The conductor rod 2 is provided with a row of slots 3 arranged at intervals. The slots 3 are provided at the top of the conductor rod 2. The bottom of the conductor rod 2 is provided with a notch 4 for the opening fixing part to be clamped. The cross section of the conductor rod 2 is generally non-circular, which can effectively prevent the opening fixing part from rotating. A transition disc 5 is provided between the conductor rod 2 and the block body 1. The diameter of the transition disc 5 is consistent with the through hole on the bracket on the electric vehicle, and the thickness is generally not greater than the bracket.

[0012] The use of the opening fixing member 6 is as follows Figure 3 As shown, the distance between the opening fixing piece 6 and the block body 1 is the thickness of the bracket, and the two ends are against the two sides of the bracket, so that the power-off switch housing is reliably fixed. The axial position of the opening fixing piece 6 can be adjusted according to the thickness of the bracket.
