Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle and motorcycle parts, specifically to a hydraulic rotary brake handle. Background Technology

[0002] Hydraulic disc brakes typically consist of a hydraulic upper cylinder, hydraulic lines, and a lower cylinder. The hydraulic upper cylinder is mounted on the handlebars of bicycles, electric two-wheelers, and motorcycles, while the lower cylinder is mounted on the discs on the frame corresponding to the front and rear wheels. The hydraulic upper cylinder and the lower cylinder are connected by hydraulic lines.

[0003] The existing hydraulic brake pump mainly includes a brake lever, a hydraulic cylinder, and a piston. When braking is required, there are two scenarios: Scenario 1: Before braking, the hand grips the lever. When braking, the fingers (usually the four fingers excluding the thumb) extend forward to touch the brake lever. This process takes a certain amount of time, delaying the braking opportunity. Moreover, during this process, only a small part of the palm and the thumb grip the lever, posing a risk of slipping off. Scenario 2: Before braking, the fingers (usually the four fingers excluding the thumb) rest on the brake lever. Although braking can be timely, this also only involves a small part of the palm and the thumb gripping the lever, posing a risk of slipping off during driving.

[0004] Therefore, this utility model proposes a hydraulic rotary brake handle. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic rotary brake handle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic rotary brake handle, including a grip, a plug blocking the outer opening of the grip, the plug being fixedly connected to the handlebar by threads, a force-saving pressure plate being connected to the outer side of the grip, the inner opening of the grip being connected to a connecting pipe, a bearing being installed inside the connecting pipe, the bearing being mounted on the handlebar, an end face cam being installed outside the connecting pipe, the push-stroke inclined surface of the end face cam contacting the main ball with a screw universal joint, and the screw universal joint being fixedly connected to the upper pump piston with a screw hole by threads.

[0007] The grip, handlebar, connecting tube, and end face cam are all tubular structures. The handlebar and the force-saving pressure plate are integrally connected or detachably connected. The starting and ending points of the push stroke slope of the end face cam are limited by limit posts.

[0008] The main ball with screw universal ball reciprocates on the inclined plane of the push stroke.

[0009] The piston of the upper pump with a screw hole is fixed to the upper pump and is part of the upper pump. The upper pump does not have a brake lever. The upper pump and the handlebar are both fixed to the handlebar. The upper pump cannot rotate, but the handlebar can rotate.

[0010] The end face cam and the connecting pipe are fixed by a locking screw through a thread. A bearing is installed inside the connecting pipe, and the locking screw passes through the connecting pipe and abuts against the bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When braking, the hand can grip the handle without having to extend the fingers to touch the brake lever, preventing slippage. The handle can be rotated immediately for braking, optimizing the operating posture, simplifying the operating process, shortening the operating time, and thus shortening the braking distance.

[0013] 2. When riding, your fingers do not need to rest on the brake lever, but rather grip the handlebars. This prevents your hands from slipping off, especially on bumpy roads and in emergency situations, thus improving riding safety.

[0014] 3. The elimination of the upper pump brake lever saves some space, which is beneficial for folding and storing the folding bike. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1-4As shown, this utility model discloses a hydraulic rotary brake lever, including a handlebar 5 with a force-saving pressure plate 4 connected to the outside of the handlebar 5. A plug 61 is blocked at the outer opening of the handlebar 5. The plug 61 is fixedly connected to the handlebar 6 by threads. The inner opening of the handlebar 5 is fixedly connected to a connecting pipe 51. A bearing 52 is installed inside the connecting pipe 51 and is mounted on the handlebar 6. An end face cam 1 is installed outside the connecting pipe 51. The push slope 13 of the end face cam 1 contacts the main ball 21 with a screw universal ball 2. The screw universal ball 2 is fixedly connected to the upper pump piston 31 with a screw hole by threads. The upper pump piston 31 with a screw hole is part of the upper pump 3. The upper pump 3 does not have a brake lever.

[0022] The handle 5 and the pressure plate 4 are either fixedly connected or detachably connected. The fixed connection can be integrally molded or welded for greater reliability; the detachable connection can be threaded or snap-fit, making it easy to replace the pressure plate 4.

[0023] The handle 5 and the connecting tube 51 are fixedly connected, which can be integrally formed or welded. The connecting tube 51 and the end face cam 1 are fixedly connected by a locking screw 14 via threads, which facilitates the replacement of the end face cam 1. The locking screw 14 passes through the connecting tube 51 and abuts against the bearing 52. The end face cam 1 has a low point limiting post 11 at the starting point and a high point limiting post 12 at the ending point of the push stroke ramp 13, which are used to limit the rotation stroke of the end face cam 1 and at the same time limit the main ball 21 with screw universal ball 2 to roll only on the push stroke ramp 13.

[0024] The upper pump 3 and the handlebar 5 are both fixed to the handlebar 6. The upper pump 3 cannot rotate, but there is a gap between the handlebar 5 and the handlebar 6, and the handlebar 5 can rotate.

[0025] In summary, the working principle of this utility model is as follows: when holding the handle 5, rotate the handle 5 when braking is needed. Users with less strength can also press the pressure plate 4 with part of their palm at the same time. The handle 5 drives the end face cam 1 to rotate synchronously. The main ball 21 with screw universal ball 2 rolls on the push stroke slope 13 from near the low point limit post 11 to the high point limit post 12. At this time, the push stroke gradually increases. The screw universal ball 2 presses the upper pump piston 31 with screw hole to move, so as to squeeze the oil through the oil pipe into the lower pump to achieve the purpose of braking. After braking is completed, the force is released, and the piston 31 with the threaded hole in the upper pump begins to return to its original position. This causes the universal ball joint 2 with the threaded rod to return to its original position. The main ball 21 of the universal ball joint 2 applies a pushing force to the inclined plane 13. Under the action of the component of the pushing force parallel to the inclined plane, the end face cam 1 begins to return to its original position, causing the handle 5 to return to its original position. As the main ball 21 returns from near the high point limit post 12 to near the low point limit post 11, all related components return to their original positions. This rotary braking method optimizes the operating posture, simplifies the operating process, and shortens the operating time, thereby shortening the braking distance and improving driving safety.

[0026] The above are all preferred embodiments of this application, used to help understand the present utility model and its core ideas. They should not be used to limit the scope of protection of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present utility model without departing from the principle of the present utility model, and these improvements and modifications also fall within the scope of protection of the claims of the present utility model.
