Description

Technical Field

[0001] This utility model relates to the field of brake lever technology, specifically to a brake lever seat. Background Technology

[0002] The brake lever holder is a core control component installed at both ends of the locomotive handlebars. It is mainly used to support the brake lever and realize the mechanical transmission and safety control of braking action. Its main body is usually made of high-strength plastic or metal and includes a fixed base, handle shaft and other structures. Some models also integrate a brake power cut-off switch inside the handlebar holder. The handlebar presses the power cut-off switch contact inside the handlebar holder through the shaft to cut off the motor power immediately and avoid power resistance during braking. After the handlebar is released, the return spring drives the handlebar back to its original position, the power cut-off switch contact closes, and the power is automatically restored.

[0003] The announcement number CN209521817U discloses an installation structure for a combination switch and brake lever for electric vehicles, including a combination switch and brake lever for mounting on the handlebars; the brake lever includes a brake seat, a brake lever, and a power-off switch, the brake seat and the combination switch are detachably connected, and the brake seat or combination switch is fastened to the handlebars by a fastener; the power-off switch is located on the combination switch, and the housing of the combination switch has a wire outlet, in which the cable connected to the power-off switch and the combination switch is laid; integrating the two together and unifying the wiring increases aesthetics, but this technology installs the power-off switch and other switches inside the housing of the combination switch, resulting in messy wiring inside the housing, and repairing the power-off switch requires disassembling the combination switch, making repairs complex and cumbersome, so this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a brake lever seat to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake lever holder, including a handlebar and a combination switch disposed on one side of the handlebar. The handlebar is hinged to one side of the combination switch. The combination switch includes a housing. The housing surface is provided with a toggle switch, and the bottom of the housing is provided with a power-off switch. The power-off switch is linked to the handlebar. The power-off switch includes a linkage end linked to the brake lever and a switch base. The linkage end is capable of reciprocating within the switch base. The linkage end has a moving contact. The switch base has a stationary contact that connects to the moving contact when braking. Moving the handlebar can drive the linkage end to reciprocate.

[0006] Using the above technical solution, an independent power-off switch is installed at the bottom of the combination switch housing. This power-off switch is linked to the handlebar via a linkage terminal. When the handlebar is moved, the linkage terminal reciprocates within the switch holder. The moving contact on the linkage terminal moves with the linkage terminal and connects with the stationary contact on the switch holder when braking occurs, thus triggering the power-off switch. The toggle switch on the housing surface and the power-off switch at the bottom are spatially separated. Because the power-off switch is independently located at the bottom of the housing, it is in a different position from the toggle switch on the surface, and their wires can be arranged separately. This avoids the wire concentration problem caused by the centralized installation of all switches inside the housing in the prior art, and reduces the tangled and messy wires inside the housing. Regarding the problem of complex and cumbersome maintenance, since the power-off switch is independently located at the bottom of the housing, when the power-off switch needs to be maintained, it is not necessary to disassemble the entire combination switch housing. The power-off switch at the bottom can be operated directly, simplifying the maintenance process.

[0007] The aforementioned brake lever holder can be further configured as follows: the handlebar includes a grip end and a hinge end hinged to the housing; the linkage end includes a linkage handle and a movable plate disposed at the bottom of the linkage handle; the movable plate can reciprocate axially within the switch holder; the hinge end has an embedded groove for the linkage handle to be embedded in; the rotation of the hinge end can drive the movable plate to reciprocate axially within the switch holder; and the moving contact is installed at the bottom of the movable plate.

[0008] Using the above technical solution, the hinge end of the handlebar is provided with an embedded groove, and the linkage handle of the linkage end is embedded in the embedded groove to realize the fixed connection between the handlebar and the linkage end; the movable plate of the linkage end is set at the bottom of the linkage handle, and the movable plate is located in the switch seat and can move axially. When the grip end of the handlebar is operated, it drives the hinge end that is hinged to the housing to rotate around the hinge point. Since the linkage handle is embedded in the embedded groove of the hinge end, the rotation of the hinge end will synchronously drive the linkage handle to move. The linkage handle then drives the movable plate at its bottom to reciprocate axially in the switch seat, realizing the axial reciprocating motion of the movable plate with the rotation of the hinge end.

[0009] The aforementioned brake lever holder can be further configured as follows: the switch holder has movable grooves on both sides, the movable plate has abutting protrusions at both ends that abut against the movable grooves, the movable plate has a through groove for the moving contact to pass through, the movable plate and the through groove have a limiting structure that limits the maximum moving distance of the moving contact, the bottom of the movable plate has an embedded mounting groove for the moving contact to be embedded, the bottom of the embedded mounting groove has a spring groove for the spring to be installed, one end of the spring abuts against the spring groove and the other end abuts against the moving contact.

[0010] Using the above technical solution, the switch base has movable slots on both sides, and the movable plate has abutting protrusions at both ends. The abutting protrusions abut against the movable slots, allowing the movable plate to move axially back and forth within the movable slots of the switch base via the abutting protrusions. The movable slots guide the abutting protrusions, restricting the movable plate to move only axially and preventing lateral displacement. The movable plate has a through slot, through which the moving contact passes. The bottom of the movable plate has an embedded mounting slot, in which the moving contact is embedded. The bottom of the embedded mounting slot has a spring slot, in which a spring is installed. One end of the spring abuts against the bottom of the spring slot, and the other end abuts against the moving contact. The spring force presses the moving contact firmly into the embedded mounting slot, achieving elastic installation of the moving contact.

[0011] The aforementioned brake lever seat can be further configured such that: the limiting structure includes limiting grooves opened at both ends of the moving contact, and a limiting protrusion is provided in the through groove; the limiting protrusion is placed in the limiting groove to limit the maximum movement distance of the moving contact.

[0012] Using the above technical solution, when the moving contact reciprocates axially within the switch holder along with the moving plate, the limiting groove moves synchronously with the moving contact. Since the limiting protrusion is fixed within the through groove and located within the limiting groove, the movement range of the limiting groove is limited by the position of the limiting protrusion. When the moving contact moves in a certain direction to the end of the limiting groove and abuts against the limiting protrusion, the limiting protrusion blocks the limiting groove from continuing to move, thereby limiting the further movement of the moving contact in that direction. Similarly, when the moving contact moves in the opposite direction to the other end of the limiting groove and abuts against the limiting protrusion, it is also blocked by the limiting protrusion. Thus, through the cooperation of the limiting groove and the limiting protrusion, the maximum axial movement distance of the moving contact is limited.

[0013] The aforementioned brake lever holder can be further configured as follows: the housing includes an upper housing and a lower housing, the toggle switch is disposed at the upper end of the upper housing, an installation groove for mounting on a locomotive is formed between the upper housing and the lower housing, the upper housing includes a hinge plate hinged to the hinge end, and the linkage end and switch seat are disposed at the lower end of the hinge plate.

[0014] Using the above technical solution, the toggle switch is located at the upper end of the upper housing; the upper housing is provided with a hinge plate for hinged with the handlebar hinge end; the linkage end and the switch seat are located at the lower end of the hinge plate; the mounting groove formed between the upper housing and the lower housing is used to realize the installation connection between the entire housing and the locomotive.

[0015] The beneficial effects of this utility model are as follows: The bottom of the housing of the combination switch is equipped with an independent power-off switch, which is located in a different position from the toggle switch on the surface. The wires of the two can be arranged separately, which avoids the phenomenon of wire concentration caused by the concentration of all switches inside the housing in the prior art.

Detailed Implementation

[0017] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0018] like Figure 1-4The present invention provides the following technical solution: a brake lever holder, including a handlebar 1 and a combination switch 2 disposed on one side of the handlebar 1. The handlebar 1 is hinged to one side of the combination switch 2. The combination switch 2 includes a housing 3, a toggle switch 4 on the surface of the housing 3, and a power-off switch 5 at the bottom of the housing 3. The power-off switch 5 is linked to the handlebar 1. The power-off switch 5 includes a linkage end 6 connected to the brake lever 1 and a switch base 7. The linkage end 6 can reciprocate within the switch base 7. The linkage end 6 has a moving contact 8. The switch base 7 has a stationary contact 9 connected to the moving contact 8 when braking. Moving the handlebar 1 can drive the linkage end 6 to reciprocate. The bottom of the housing 3 of the combination switch 2 is provided with an independent power-off switch 5. This power-off switch 5 is linked to the handlebar 1 through the linkage end 6. When the handlebar 1 is moved, it will drive the linkage end 6 to reciprocate. The switch base 7 reciprocates within the switch, and the moving contact 8 on the linkage end 6 moves with the linkage end 6. When the braking action occurs, it connects with the stationary contact 9 on the switch base 7, thereby completing the triggering action of the power-off switch 5. The toggle switch 4 on the surface of the housing 3 and the power-off switch 5 at the bottom are spatially separated. Since the power-off switch 5 is independently set at the bottom of the housing 3, and is located in a different position from the toggle switch 4 on the surface, the wires of the two can be arranged separately, avoiding the phenomenon of wire concentration caused by the centralized installation of all switches inside the housing 3 in the prior art, and reducing the cross-contamination and mess of wires inside the housing 3. To address the problem of complex and cumbersome maintenance, since the power-off switch 5 is independently set at the bottom of the housing 3, when it is necessary to maintain the power-off switch 5, it is not necessary to disassemble the entire combination switch 2 housing 3. The power-off switch 5 at the bottom can be operated directly, simplifying the maintenance process.

[0019] like Figure 1-4The present invention provides the following technical solution: a brake lever seat, the handlebar 1 includes a grip end 10 and a hinge end 11 hinged to the housing 3, the linkage end 6 includes a linkage handle 12 and a movable plate 13 disposed at the bottom of the linkage handle 12, the movable plate 13 can move axially back and forth within the switch seat 7, the hinge end 11 has an embedded groove 14 for the linkage handle 12 to be embedded in, the rotation of the hinge end 11 can drive the movable plate 13 to move axially back and forth within the switch seat 7, the moving contact 8 is installed at the bottom of the movable plate 13, the hinge end 11 of the handlebar 1 has an embedded groove 14, the linkage handle 12 of the linkage end 6 is embedded in the embedded groove 14, realizing the fixed connection between the handlebar 1 and the linkage end 6;The movable plate 13 of the linkage end 6 is located at the bottom of the linkage handle 12, and the movable plate 13 is located inside the switch base 7 and can move axially. When the grip end 10 of the handlebar 1 is operated, it drives the hinge end 11, which is hinged to the housing 3, to rotate around the hinge point. Since the linkage handle 12 is embedded in the inner groove 14 of the hinge end 11, the rotation of the hinge end 11 will synchronously drive the linkage handle 12 to move. The linkage handle 12 then drives the movable plate 13 at its bottom to reciprocate axially inside the switch base 7, realizing the axial reciprocating motion of the movable plate 13 with the rotation of the hinge end 11. The switch base 7 has movable grooves 15 on both sides, and the movable plate 13 has abutting protrusions at both ends that abut against the movable grooves 15. Block 16, the movable plate 13 has a through groove 17 for the moving contact 8 to pass through, and a limiting structure between the movable plate 13 and the through groove 17 to limit the maximum movement distance of the moving contact 8. The bottom of the movable plate 13 has an embedded mounting groove 2318 for the moving contact 8 to be embedded in, and the bottom of the embedded mounting groove 2318 has a spring groove 20 for the spring 19 to be installed. One end of the spring 19 abuts against the spring groove 20 and the other end abuts against the moving contact 8. The switch base 7 has moving grooves 15 on both sides, and the movable plate 13 has abutting protrusions 16 at both ends. The abutting protrusions 16 abut against the moving grooves 15, so that the movable plate 13 can move axially back and forth in the moving grooves 15 of the switch base 7 through the abutting protrusions 16. The movable groove 15 guides the abutment protrusion 16, restricting the movable plate 13 to move only axially and preventing lateral displacement. A through groove 17 is provided within the movable plate 13, through which the movable contact 8 passes. An embedded mounting groove 2318 is provided at the bottom of the movable plate 13, in which the movable contact 8 is embedded. A spring groove 20 is provided at the bottom of the embedded mounting groove 2318, and a spring 19 is installed within it. One end of the spring 19 abuts against the bottom of the spring groove 20, and the other end abuts against the movable contact 8. The spring force of the spring 19 presses the movable contact 8 firmly within the embedded mounting groove 2318, achieving elastic installation of the movable contact 8. The limiting structure includes... Limiting grooves 21 are opened at both ends of the moving contact 8. Limiting protrusions 22 are provided in the through groove 17. The limiting protrusions 22 are placed in the limiting grooves 21 to limit the maximum movement distance of the moving contact 8. When the moving contact 8 moves axially back and forth in the switch base 7 with the moving plate 13, the limiting grooves 21 move synchronously with the moving contact 8. Since the limiting protrusions 22 are fixed in the through groove 17 and located in the limiting grooves 21, the movement range of the limiting grooves 21 is limited by the position of the limiting protrusions 22. When the moving contact 8 moves in a certain direction to the end of the limiting grooves 21 and abuts against the limiting protrusions 22, the limiting protrusions 22 block the limiting grooves 21 from continuing to move, thereby limiting the further movement of the moving contact 8 in that direction.Similarly, when the moving contact 8 moves in the opposite direction to the other end of the limiting groove 21 and abuts against the limiting protrusion 22, it is also blocked by the limiting protrusion 22. Thus, through the cooperation of the limiting groove 21 and the limiting protrusion 22, the maximum axial movement distance of the moving contact 8 is limited. The housing 3 includes an upper housing 301 and a lower housing 302. The toggle switch is located at the upper end of the upper housing 301. A mounting groove 23 for installation on the locomotive is formed between the upper housing 301 and the lower housing 302. The upper housing 301 includes... A hinge plate 301a hinged to the hinge end 11, a linkage end 6, and a switch base 7 are disposed at the lower end of the hinge plate 301a. A toggle switch 4 is disposed at the upper end of the upper housing 301. The upper housing 301 has a hinge plate 301a for hinged to the hinge end 11 of the handlebar 1. The linkage end 6 and the switch base 7 are disposed at the lower end of the hinge plate 301a. The mounting groove 23 formed between the upper housing 301 and the lower housing 302 is used to achieve the installation connection between the entire housing 3 and the locomotive.

[0020] The beneficial effects of this utility model are as follows: The bottom of the housing 3 of the combination switch 2 is provided with an independent power-off switch 5, which is located in a different position from the toggle switch 4 on the surface. The wires of the two can be arranged separately, which avoids the phenomenon of wire concentration caused by the concentration of all switches inside the housing 3 in the prior art.
