Description

Technical Field

[0001] The invention belongs to the field of bicycle accessories, and in particular relates to a bicycle control device. Background Art

[0002] The existing bicycle control device is described in Chinese patent CN 205632877 U: single handle operation mode, pushing the handle at a large angle is for shifting, and pushing the handle at a small angle is for shifting, which is easy to cause misoperation in emergency situations; and if the shifting is on the side of the handle, the whole product will look bulky, and since the shifting handle is set on the windward side, it will also increase the wind resistance when riding. Therefore, it can be seen from the above two structures that the position of the shifting handle in the existing structure is unreasonable, which will not only cause misoperation in the tense state of high-speed riding, but also increase wind resistance and affect the riding speed. Therefore, it is necessary to improve the existing bicycle control device to reduce misoperation and reduce wind resistance. Summary of the invention

[0003] In view of the problem that the existing bicycle control devices are prone to misoperation, the present invention provides a bicycle control device that is easy to operate. The shifting handle and the shifting handle are arranged to move in different directions to quickly distinguish between shifting and shifting, thereby effectively avoiding misoperation. At the same time, the shifting handle is arranged at the lower part of the shell, which can effectively reduce wind resistance.

[0004] The technical solution adopted by the present invention is as follows: a bicycle control device includes a shell and a speed change unit arranged in the shell, a push-type shift down handle is provided at the lower part of the shell, the working direction of the push-type shift down handle is a first direction, and the first direction is perpendicular to the speed change unit, and a toggle-type shift forward handle is provided on the front side of the shell, the working direction of the toggle-type shift forward handle is a second direction, and the second direction is parallel to the speed change unit.

[0005] In the present application, a push-type shift down handle is arranged at the lower part of the shell and a toggle shift up handle is arranged at the front side of the shell. This structure can distinguish between shifting and shifting by performing different actions of the two handles, effectively reducing the possibility of misoperation. The shift down handle is arranged at the lower part of the shell, which can effectively reduce wind resistance and improve the riding experience.

[0006] Furthermore, the speed change unit comprises:

[0007] A cable pull disk is connected to the speed change cable; the cable pull disk is returned by a first return spring;

[0008] A ratchet disc, which is provided with internal ratchets; the ratchet disc rotates synchronously with the wire pulling disc;

[0009] A gear shifting assembly, which is linked with the ratchet plate and the toggle gear shifting handle;

[0010] A retraction claw, which is arranged on one side of the ratchet plate and is linked with the push-type retraction handle;

[0011] A returnable paddle is provided between the gear-advancing assembly and the ratchet plate, the paddle abuts against the inner ratchet, and the gear-reversing claw is close to the paddle;

[0012] When the toggle-type gear-advancing handle is in operation, the paddle is driven to slide along the inner ratchet surface, thereby driving the ratchet disk to rotate in the positive direction to achieve gear-advancing;

[0013] When the push-type gear-reversing handle is in operation, the gear-reversing claw is driven to contact the surface of the paddle, so that the paddle is disengaged from the inner ratchet, and then the ratchet plate rotates in the opposite direction under the action of the first return spring to achieve gear reversal.

[0014] In the speed change unit, both shifting and retarding are accomplished by a paddle disposed between the shift assembly and the ratchet plate, and the paddle is surrounded by the shift assembly and the ratchet plate and will not fall out easily, thus ensuring structural stability.

[0015] As an improvement, the gear shifting assembly comprises a rotating disk coaxially arranged with the ratchet disk, an extension handle is rotatably connected to one side of the rotating disk, and the toggle type gear shifting handle abuts against a side surface of the extension handle.

[0016] The preferred solution is that the extension handle, the shift plate and the ratchet plate are arranged on the same connecting shaft.

[0017] As another improvement, the gear-advancing assembly includes a rotating disk and an extension part used in conjunction with each other, the rotating disk is coaxially arranged with the ratchet disk, the extension part is rotatably connected to the housing, a first beveled tooth is arranged on the periphery of the rotating disk, a second beveled tooth that can cooperate with the first beveled tooth is arranged on the periphery of the extension part, and the extension part contacts the toggle-type gear-advancing handle. When the toggle-type gear-advancing handle drives the extension part to rotate, the extension part drives the rotating disk to rotate, thereby causing the ratchet disk and the wire pull disk to rotate synchronously to achieve gear-advancing.

[0018] Furthermore, the push-type shift-back handle includes a handle portion and a connecting rod portion connected to the handle portion, the handle portion is arranged on the outside of the shell, and the connecting rod portion is located inside the shell, the connecting rod portion extends toward and contacts the shift-back claw, and when the handle portion is subjected to external force, the connecting rod portion is driven to apply force to the shift-back claw.

[0019] Furthermore, a rotating shaft is provided at the connection between the connecting rod part and the handle part, and a spring is provided on the rotating shaft to enable the push-type gear retraction to return to the original position.

[0020] Furthermore, the ratchet plate is provided with an outer ratchet, and a back-stop pawl is used in conjunction with the outer ratchet to achieve back-stopping, ensuring that only one gear is advanced or retracted each time.

[0021] Furthermore, the anti-retraction pawl abuts against the retraction pawl. When the retraction pawl is driven by the push-type retraction drive, the retraction pawl pushes the anti-retraction pawl outwards to release the limit on the ratchet disk.

[0022] Furthermore, a positioning plate is provided between the gear advancement assembly and the ratchet plate, and the back-stop pawl is provided on the positioning plate.

[0023] Furthermore, a brake handle is provided on the housing, the toggle-type gear shift handle is arranged on the brake handle, and the limiting is achieved through the brake handle.

[0024] The beneficial effects of the present invention are as follows: the present application is a bicycle control device, which adopts a push-type shift down handle arranged at the lower part of the shell and a toggle-type shift up handle arranged at the front side of the shell. This structure can distinguish between shifting down and shifting gears by performing different actions of the two handles, effectively reducing the possibility of misoperation. The shift down handle is arranged at the lower part of the shell, which can effectively reduce wind resistance and improve the riding experience. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0035] Example 1

[0036] like Figures 1 to 5 As shown, this embodiment is a bicycle control device, including a housing 1 and a shift unit 3 arranged in the housing 1, a push-type shift down handle 2 is provided at the lower part of the housing 1, and the working direction of the push-type shift down handle 2 is a first direction, and the first direction is perpendicular to the shift unit 3, and a toggle type shift forward handle 4 is provided on the front side of the housing 1, and the working direction of the toggle type shift forward handle 4 is a second direction, and the second direction is parallel to the shift unit 3.

[0037] In the present application, a push-type shift down handle 2 is arranged at the lower part of the shell 1 and a toggle shift up handle 4 is arranged at the front side of the shell 1. This structure can distinguish between shifting and shifting by performing different actions of the two handles, effectively reducing the possibility of misoperation. The shift down handle is arranged at the lower part of the shell 1, which can effectively reduce wind resistance and improve the riding experience.

[0038] The speed change unit 3 comprises:

[0039] A connecting shaft 11, which plays a fixing role;

[0040] The cable pull drum 31 is connected to the speed change cable 5 and is arranged on the connecting shaft 11; the cable pull drum 31 is returned by a first return spring;

[0041] A ratchet disc 32, which is provided with inner ratchet teeth 321 and outer ratchet teeth 322; the ratchet disc 32 rotates synchronously with the wire pulling disc 31;

[0042] The anti-retraction claw 38 is used in conjunction with the outer ratchet 322 to achieve anti-retraction, ensuring that only one gear is advanced or retracted each time;

[0043] A gear shift assembly, which is linked with the ratchet plate 32 and the toggle gear shift handle 4; the gear shift assembly includes a rotating plate 35 arranged on the connecting shaft 11, an extension handle 36 is rotatably connected to one side of the rotating plate 35, and the toggle gear shift handle 4 abuts against the side of the extension handle 36;

[0044] A retraction claw 33, which is arranged on one side of the ratchet plate 32 and is linked with the push-type retraction handle 2;

[0045] The paddle 34 is disposed between the rotating disk 35 and the ratchet disk 32; the paddle 34 abuts against the inner ratchet 321, and the retraction claw 33 is close to the paddle 34; the paddle 34 is returned by a first return torsion spring 341;

[0046] The push-type gear-reversing handle 2 comprises a handle portion 21 and a connecting rod portion 22 connected to the handle portion 21. The handle portion 21 is arranged on the outside of the housing 1. The windward surface of the handle portion 21 is streamlined to effectively reduce wind resistance. The connecting rod portion 22 is located inside the housing 1. The connecting rod portion 22 extends toward and contacts the gear-reversing claw 33. When the handle portion 21 is subjected to an external force, the connecting rod portion 22 is driven to apply force to the gear-reversing claw 33. A rotating shaft 23 is provided at the connection between the connecting rod portion 22 and the handle portion 21. A spring 231 is provided on the rotating shaft 23, so that the push-type gear-reversing is returned to its original position.

[0047] In this embodiment, the back-stop pawl 38 and the back-shift pawl 33 are coaxially arranged, and the back-shift pawl 33 is provided with an extension portion, which can abut against the side of the back-stop pawl 38, so that when the back-shift pawl 33 is driven by the push-type back-shifting, the back-shift pawl 33 pushes the back-stop pawl 38 outward to release the limit on the ratchet plate 32;

[0048] When the shift-type gear-advancing handle 4 is in operation, the shifting piece 34 is driven to slide along the surface of the inner ratchet 321, thereby driving the ratchet plate 32 to rotate in the positive direction to achieve gear-advancing;

[0049] When the push-type gear-reversing handle 2 is working, the gear-reversing claw 33 is driven to contact the surface of the paddle 34, so that the paddle 34 disengages from the inner ratchet 321 and the gear-reversing claw 38 disengages from the outer ratchet 322, thereby releasing the limit on the ratchet plate 32, and then the ratchet plate 32 rotates in the opposite direction under the action of the first return spring 311 to achieve gear reversal.

[0050] In the speed change unit 3, both shifting and retarding are accomplished by a paddle 34 disposed between the shift assembly and the ratchet plate 32, and the paddle 34 is surrounded by the shift assembly and the ratchet plate 32 and will not fall out easily, thereby ensuring structural stability.

[0051] A positioning plate 39 is provided between the rotating disk 35 and the ratchet plate 32. The retracting claw 33 and the stop claw 38 are coaxially arranged on the positioning plate 39 (the shaft connecting the two is not shown in the figure), and return to their original positions through the second return torsion spring 381. The positioning plate 39 plays a fixing role, which can not only facilitate the arrangement of the retracting claw 33 and the stop claw 38, but also facilitate the connection of the entire speed change unit into a whole. The rotating disk 35 can return to its original position through the second return spring 352. In this embodiment, the second return spring 352 is provided on the connecting shaft 11 and is located between the rotating disk 35 and the extension handle 36. The extension handle 36 can also return to its original position through the second spring 231.

[0052] The housing 1 is also provided with a brake handle 6, one end of a brake line 61 is connected to the brake handle 6, and the other end extends through the housing 1, the toggle-type shift handle 4 is arranged on the brake handle 6, and the position is limited by the brake handle 6. In this embodiment, the brake handle 6 and the shift handle have different movement directions, and will not affect each other when working separately.

[0053] Example 2

[0054] like Figure 6 , Figure 7 and Figure 8 As shown, the difference between this embodiment and the embodiment 1 is that: the gear-advancing assembly includes a rotating disk 35 and an extension 37 used in conjunction with each other, the rotating disk 35 is coaxially arranged with the ratchet disk 32, the extension 37 is rotatably connected to the housing 1, the periphery of the rotating disk 35 is provided with a first beveled tooth 351, the periphery of the extension 37 is provided with a second beveled tooth 371 that can cooperate with the first beveled tooth 351, and the extension 37 is in conflict with the toggle-type gear-advancing handle 4. When the toggle-type gear-advancing handle 4 drives the extension 37 to rotate, the extension 37 drives the rotating disk 35 to rotate, thereby causing the ratchet disk 32 and the wire pull disk 31 to rotate synchronously to achieve gear-advancing. This embodiment uses the first beveled tooth 351 and the second beveled tooth 371 to convert the swinging action of the gear-advancing assembly into a rotational action, with a compact structure, ingenious design, no jamming, and a relatively stable structure.

[0055] The push-type gear-reversing handle 2 includes a handle portion 21 and a connecting rod portion 22 connected to the handle portion 21. The handle portion 21 is arranged on the outside of the housing 1. The windward surface of the handle portion 21 is streamlined to effectively reduce wind resistance. The connecting rod portion 22 is located inside the housing 1. The connecting rod portion 22 extends toward and contacts the gear-reversing claw 33. When the handle portion 21 is subjected to an external force, the connecting rod portion 22 is driven to apply force to the gear-reversing claw 33. A rotating shaft 23 is provided at the connection between the connecting rod portion 22 and the handle portion 21. A spring 231 is provided on the rotating shaft 23 to return the push-type gear-reversing handle 2 to its original position. The retraction claw 33 and the stop claw 38 are connected by the connecting piece 221, and the connecting rod portion 22 abuts against the surface of the connecting piece 221. Through the force applied by the connecting piece 221, the retraction claw 33 and the stop claw 38 are pushed apart and rotated in the opposite direction at the same time, and then the retraction claw 33 pushes the paddle 34, so that the paddle 34 disengages from the inner ratchet 321 and the stop claw 38 disengages from the outer ratchet 322, and only one gear is retracted each time.
