Description

Technical Field

[0001] This invention relates to a gear shift cable mounting structure and a combined gear shift and brake controller. Background Technology

[0002] Many devices can transmit power by changing the ratio between input and output forces through a speed-changing mechanism, thereby achieving the effects of saving effort and changing speed.

[0003] For example, variable-speed bicycles are popular with consumers because their gears can be switched according to different driving conditions (flat surfaces, uphill, downhill, etc.). The controller for controlling the gears on such a bicycle is fixed to a part of the bicycle (e.g., the handlebars) via a clamp, allowing for convenient operation near the hand. Switching the controller actuates a gear cable to change the gear position.

[0004] In existing technologies, when manufacturing and installing integrated transmission and braking controllers, manufacturers must first thread the transmission cable through the controller, which is not fully enclosed in the housing, and then fully assemble the housing. In other words, the installation and removal of existing transmission cables requires the separation of a portion of the housing; otherwise, installation cannot be completed. Therefore, the manufacturing, production, and installation / removal steps are cumbersome, inconvenient, time-consuming, and labor-intensive.

[0005] In another existing technology, when producing a controller that combines shifting and braking, the gear cable mounting hole is opened between the controller housing and the brake lever and the bicycle handlebar. Since the brake lever will block the opening of the mounting hole, if the mounting hole is to be opened on this side, the cable winding structure must be avoided from the brake lever, which increases the overall thickness of the controller, increases transportation costs and product weight, and fails to achieve lightweighting.

[0006] Therefore, it is necessary to provide a novel and progressive gear cable mounting structure and a combined gear and brake controller to solve the above problems. Summary of the Invention

[0007] The main objective of this invention is to provide a gear cable installation structure and a combined gear and brake controller, which allows for direct installation of the gear cable without separating the housing of the combined gear and brake controller, making the process simple, convenient, time-saving, and labor-saving.

[0008] To achieve the above objectives, the present invention provides a gear cable mounting structure and a combined gear and brake controller.

[0013] As a preferred embodiment of the above technical solution, the winding structure includes a mounting hole for positioning and installing the speed change cable, and an extension of the cable through the mounting hole passes through the clamp.

[0014] As a preferred embodiment of the above technical solution, preferably, the extension line passes through the two opposite ends of the through hole of the clamp.

[0015] As a preferred embodiment of the above technical solution, preferably, the mounting hole can be viewed from the outside through the wire hole when viewed from the direction of the extension line.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please refer to Figures 1 to 10 This shows a preferred embodiment of the present invention, wherein the gear cable mounting structure 1 of the present invention is provided in a gear and brake combined controller 100, the gear cable mounting structure 1 includes a housing 10, a brake operating lever 20, a gear structure 30, a mounting part 40 and a wire hole 50.

[0029] The housing 10 includes at least one first wall portion 11; the brake operating lever 20 is disposed in the housing 10 for operating the brake; the transmission structure 30 is disposed inside the housing 10, the transmission structure 30 includes a winding structure 31 and a spindle 32, the winding structure 31 is rotatable around the spindle 32, the spindle 32 has a first axis 321; the mounting portion 40 includes a clamp 41 for mounting on a handlebar 200, the clamp 41 is connected to the first wall portion 11, and the clamp 41 A through hole 411 is provided, and the through hole 411 has a through hole axis 412. A first reference plane P1 is defined through the through hole axis 412 and perpendicular to the first reference plane 321, and a second reference plane P2 is defined through the through hole axis 412 and perpendicular to the first reference plane P1. A wire hole 50 is provided in the first wall portion 11 and is configured to face the second reference plane P2. A gear cable 300 passes through the wire hole 50 and connects to the winding structure 31. In this way, without separating the housing 10 of the gear and brake integrated controller 100, the gear cable 300 can be directly inserted into the gear and brake integrated controller 100 through the wire hole 50 to complete the installation. The steps are simple, convenient, time-saving, and labor-saving.

[0030] Preferably, the clamp 41 and the cable hole 50 are configured to face the handlebar 200, so that the cable hole 50 is shielded by the handlebar 200, preventing foreign objects from entering and providing protection, and is also more aesthetically pleasing. The brake lever 20 is preferably located on the first reference plane P1, in a position that is easy to operate.

[0031] Preferably, the threading hole 50 is located within a 20mm range above and below the first reference plane P1, a portion of the threading hole 50 is located within the extension range of the clamp 41, the threading hole 50 is located on the side of the second reference plane P2 near the winding structure 31, and the threading hole 50 is located on the side of the clamp 41 near the winding structure 31 (see reference). Figure 2The winding structure 31 includes a mounting hole 311 for positioning and mounting the transmission cable 300. An extension L1 of the cable passing through the through hole 50 passes through the clamp 41, and the extension L1 passes through the two opposite ends of the through hole 411 of the clamp 41 (e.g., ...). Figure 6 Viewed from the direction of the extension line L1, the mounting hole 311 can be viewed from the outside through the wire hole 50. In this way, the gear cable 300 can pass through the through hole 411 and into the wire hole 50 relatively straight without interference, and can be accurately aligned with the mounting hole 311, so the installation of the gear cable 300 is quick and accurate.

[0032] The present invention also provides a combined speed and brake controller 100, including a speed cable mounting structure 1 as described above, and at least one speed operation lever 60. The at least one speed operation lever 60 is movably (rotatably, by pressing or other possible actuation) disposed in the housing 10. The at least one speed operation lever 60 extends inside the housing 10 (for direct or indirect connection to the cable winding structure 31) and extends outside the housing 10 (for external operation). The at least one speed operation lever 60 is operated to actuate the speed cable 300.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
