Description

Technical Field

[0001] This utility model relates to the field of throttle structure for vehicles, and particularly to a double-wire throttle. Background Technology

[0002] The practice of controlling vehicle power via a throttle has become quite common. In addition to the widely used Hall effect technology for accurate acquisition of power output commands, there is another method that directly acquires power output commands through purely mechanical means.

[0003] Specifically, a control cable is typically securely mounted on the throttle, and this cable connects to the power control mechanism. When the operator rotates the throttle, the power output is precisely controlled via the control cable. In certain application scenarios, to further enhance structural strength and increase system redundancy, the control cable is designed with a dual-wire configuration. This ensures that if one wire fails, the other continues to function normally, thereby guaranteeing the stability and reliability of the power control.

[0004] While the introduction of dual control cables offers the aforementioned advantages, it also results in greater rotational resistance of the throttle and makes the control cables prone to interference. Utility Model Content

[0005] The main purpose of this utility model is to provide a dual-line throttle, which aims to solve the problem that while the introduction of dual control lines into the vehicle throttle has advantages, it also results in greater rotational resistance and the control lines are prone to mutual interference.

[0006] To achieve the above objectives, this utility model provides a dual-wire throttle, comprising:

[0007] A handle base includes a base body, on which a rotating base and a cable inlet are respectively provided. The cable inlet includes two cable inlet channels, and the central axis of the rotating base is arranged parallel to or perpendicular to the cable inlet channels.

[0008] A rotating body is rotatably mounted on the rotating base, and the rotating body is provided with two wire-locking ports;

[0009] A handle is attached to the rotating body;

[0010] The first wheel axle is rotatably disposed inside the seat body, and a first groove ring is provided circumferentially on the outer wall of the first wheel axle;

[0011] The second wheel axle is rotatably disposed within the seat body. A second groove ring is provided circumferentially on the outer wall of the second wheel axle. The planes where the second wheel axle and the first groove ring are located respectively correspond to one of the cable inlet channels.

[0012] The two external control lines enter the handle base through the two inlet channels and are then connected to the two cable clamps by the reversal of the first and second groove rings.

[0013] Furthermore, the diameter of the second groove ring is 1.3 to 2 times the diameter of the first groove ring.

[0014] Furthermore, the second axle and the first axle are rotatably arranged relative to each other.

[0015] Furthermore, a wheel axle seat is provided inside the seat body, a first lubricating ring is provided on the outer sleeve of the wheel axle seat, the first wheel axle is sleeved and fixed outside the first lubricating ring, and the second wheel axle and the first wheel axle are sleeved on each other and a second lubricating ring is provided between the sleeve interfaces.

[0016] Furthermore, the materials of the first lubricating ring and the second lubricating ring are selected from polytetrafluoroethylene and graphite.

[0017] Furthermore, the handle seat also includes a retaining bolt assembly, which is connected to the wheel axle seat and presses the second lubrication ring in place.

[0018] Furthermore, the handle seat also includes a side cover, which is connected to the seat body to fix the combination formed by the second wheel axle and the first wheel axle, and the fixing bolt assembly fixes the side cover to the handle seat.

[0019] Furthermore, the second axle and the first axle are an integral structure.

[0020] Furthermore, the rotating body and the handle are integrally formed.

[0021] Furthermore, both the second axle and the first axle are made of polymer material.

[0022] The dual-wire throttle provided by this utility model has a first groove and a second groove on the outer circumferential surface of the first and second axles, respectively. The two control wires enter from an inlet channel and are connected to the cable clamping port through the transition of the first and second grooves. Since both the second and first axles are rotatable, the two control wires on the second and first axles can operate smoothly. The tightening and releasing of the handle are smoother and safer.

[0031] Reference Figures 1 to 5 In one embodiment of this utility model, a dual-wire throttle includes:

[0032] The handle base 100 includes a base body 110, on which a rotating base 111 and a cable inlet 112 are respectively provided. The cable inlet 112 includes two cable inlet channels 113. The central axis of the rotating base 111 is arranged parallel to or perpendicular to the cable inlet channels 113.

[0033] A rotating body 200 is rotatably mounted on the rotating base 111, and the rotating body 200 is provided with two wire-locking ports 210;

[0034] Handle 300 is connected to the rotating body 200;

[0035] The first wheel axle 400 is rotatably disposed within the seat body 110, and a first groove ring 410 is provided circumferentially on the outer wall of the first wheel axle 400;

[0036] The second wheel shaft 500 is rotatably disposed within the seat body 110. A second groove ring 510 is provided circumferentially on the outer wall of the second wheel shaft 500. The planes where the second wheel shaft 500 and the first groove ring 410 are located correspond to one of the cable inlet channels 113.

[0037] The two external control lines enter the handle base 100 through the two inlet channels 113, and are then connected to the two cable clamps 210 by the reversal of the first groove ring 410 and the second groove ring 510.

[0038] In the existing technology, while the introduction of dual control lines has the above advantages, it also results in greater rotational resistance of the throttle and the control lines are prone to mutual interference.

[0039] The dual-wire throttle provided by this utility model includes a handle base 100 comprising a base body 110. The base body 110 is respectively provided with a rotating base 111 and a cable inlet 112. The cable inlet 112 includes two cable inlet channels 113. The two cable inlet channels 113 can be separate or interconnected. The central axis of the rotating base 111 is arranged parallel or perpendicular to the cable inlet channels 113; the specific positional relationship is selected according to the actual design structure.

[0040] The rotating body 200 is rotatably mounted on the rotating base 111. The mounting and fixing methods of the rotating body 200 and the rotating base 111 can be varied; specific methods are not the focus here, but can be referenced from various forms in the prior art. The rotating body 200 is provided with two wire-locking ports 210, through which the control wire is fixed.

[0041] The handle 300 is connected to the rotating body 200, and the rotation of the handle 300 drives the rotation of the rotating body 200. The rotating body 200 and the handle 300 can be a separate connection structure or an integral connection structure, depending on the actual situation.

[0042] The first axle 400 is disposed within the base body 110. A first groove ring 410 is circumferentially provided on the outer wall of the first axle 400. The second axle 500 is disposed within the base body 110. A second groove ring 510 is circumferentially provided on the outer wall of the second axle 500. The planes containing the second axle 500 and the first groove ring 410 each correspond to an inlet channel 113. After entering from one inlet channel 113, the two control lines are connected to the cable clamping port 210 through the transition of the first groove ring 410 and the second groove ring 510, respectively. By making both the second axle 500 and the first axle 400 rotatable, the two control lines on the second axle 500 and the first axle 400 can operate smoothly. For example, a fixed shaft can be provided on the handle base 100, and the second axle 500 and the first axle 400 can be sleeved on the fixed shaft, thereby enabling the second axle 500 and the first axle 400 to perform rotational movements.

[0043] In summary, the outer circumferential surfaces of the first wheel shaft 400 and the second wheel shaft 500 are respectively provided with a first groove ring 410 and a second groove ring 510. After the two control lines enter from an inlet channel 113, they are connected to the cable clamping port 210 through the transition of the first groove ring 410 and the second groove ring 510. By making both the second wheel shaft 500 and the first wheel shaft 400 rotatable, the two control lines on the second wheel shaft 500 and the first wheel shaft 400 can operate smoothly. The tightening and releasing of the handle 300 are smoother and safer.

[0044] Reference Figures 3 to 4 In one embodiment, the diameter of the second groove ring 510 is 1.3 to 2 times the diameter of the first groove ring 410.

[0045] In this embodiment, the diameter of the second groove ring 510 is differentiated from the diameter of the first groove ring 410, thereby providing a spatial basis for the layout of the two control lines.

[0046] Reference Figures 3 to 4 In one embodiment, the second axle 500 and the first axle 400 are rotatably disposed relative to each other.

[0047] In this embodiment, considering that the diameters of the second axle 500 and the first axle 400 are not the same, when the two control lines are pulled by the rotation of the rotating body 200, the rotation angles of the second axle 500 and the first axle 400 should be different. Therefore, the second axle 500 and the first axle 400 are configured to rotate relative to each other, so that the movement of the two control lines on both axles can be smooth. The relative rotation between the second axle 500 and the first axle 400 can be achieved in various ways, such as setting the second axle 500 and the first axle 400 as separate parts and restricting their connection in the circumferential direction.

[0048] Reference Figures 3 to 4 In one embodiment, a wheel axle seat 114 is provided inside the seat body 110. A first lubricating ring 600 is sleeved on the wheel axle seat 114. The first wheel axle 400 is sleeved and fixed outside the first lubricating ring 600. The second wheel axle 500 and the first wheel axle 400 are sleeved on each other and a second lubricating ring 700 is provided between the sleeve interfaces.

[0049] In this embodiment, the first axle 400 is fixed on the axle seat 114, and a first lubricating ring 600 is provided between the first axle 400 and the axle seat 114. A ring-shaped platform extends from the end face of the first axle 400, and the second axle 500 is fitted onto the ring-shaped platform, with a second lubricating ring 700 provided between them. With this structural arrangement, the second axle 500 and the first axle 400 can rotate relative to each other, and the first axle 400 can rotate independently. The first lubricating ring 600 and the second lubricating ring 700 can be made of self-lubricating materials, such as polytetrafluoroethylene or graphite.

[0050] In one embodiment, the materials of the first lubricating ring 600 and the second lubricating ring 700 are selected from polytetrafluoroethylene and graphite.

[0051] In this embodiment, two material options are provided for the first lubrication ring 600 and the second lubrication ring 700 to meet the lubrication and strength requirements.

[0052] Reference Figures 3 to 4 In one embodiment, the handle seat 100 further includes a retaining bolt assembly 800, which is connected to the wheel axle seat 114 and presses and fixes the second lubrication ring 700.

[0053] In this embodiment, a retaining bolt assembly 800 is provided to provide a basis for fixing the combination formed by the second wheel axle 500 and the first wheel axle 400. The retaining bolt assembly 800 can be threaded to the wheel axle seat 114 and fix the second lubricating ring 700, at which time the rotation of the first lubricating ring 600 and the second lubricating ring 700 is not restricted.

[0054] In one embodiment, the handle seat 100 further includes a side cover connected to the seat body 110 to fix the combination formed by the second wheel axle 500 and the first wheel axle 400, and the fixing bolt assembly 800 fixes the side cover to the handle seat 100.

[0055] In this embodiment, a side cover is provided to form a closure, and the side cover is fixed by a fixing bolt assembly 800, which reduces the difficulty of maintenance.

[0056] In one embodiment, the second axle 500 and the first axle 400 are an integral structure.

[0057] In this embodiment, the second wheel axle 500 and the first wheel axle 400 are constrained to form an integral structure, thereby reducing the difficulty of installation and disassembly.

[0058] In one embodiment, the rotating body 200 and the handle 300 are integrally formed.

[0059] In this embodiment, the rotating body 200 and the handle 300 are restricted to a single molded structure, thereby reducing the difficulty of installation and disassembly, and also eliminating the possibility of failure of the connection between the rotating body 200 and the handle 300.

[0060] In one embodiment, the second axle 500 and the first axle 400 are made of polymer material.

[0061] In this embodiment, the materials of the second wheel axle 500 and the first wheel axle 400 are limited to polymers, PVC, or polyurethane, thereby reducing the risk of damage to the control line by the second wheel axle 500 and the first wheel axle 400.

[0062] In summary, the dual-wire throttle provided by this utility model has a first groove ring 410 and a second groove ring 510 respectively arranged on the outer circumferential direction of the first wheel shaft 400 and the second wheel shaft 500. After the two control wires enter from a wire inlet channel 113, they are connected to the wire clamping port 210 through the transition of the first groove ring 410 and the second groove ring 510. By making both the second wheel shaft 500 and the first wheel shaft 400 rotatable, the two control wires on the second wheel shaft 500 and the first wheel shaft 400 can operate smoothly. The tightening and releasing of the handle 300 are smoother and safer.
