Description

Press handle grip adjustment structure

This invention belongs to the technical field of hydraulic brakes. Specifically, it is a lever grip adjustment structure applied to a hidden hydraulic brake set, so that the lever grip distance can be adjusted conveniently and quickly without using tools to meet the different braking force requirements of riders and further enhance driving safety.

According to the law, bicycles can not only be used as a means of transportation, but also can be used for sports and leisure. With the improvement of manufacturing technology and road surface, the performance and quality of various bicycles have been continuously improved, and the driving speed has also been increased invisibly. The brake system of the above-mentioned vehicles has gradually developed from the traditional brake system using rubber to brake pads to a disc brake system. At the same time, the braking action of the disc brake system has also developed from the action method of the handle driving the caliper through the pull wire to the action method of the handle pushing the hydraulic oil, so as to prompt the hydraulic oil in the oil circuit to push the brake caliper to achieve the braking effect;

The existing hydraulic brake system is composed of a brake group installed on the handlebar tube and a caliper group installed on the frame, wherein the brake group is provided with an oil pump base connected to the oil pipe on the handlebar tube, and a selectively pressurized handle is centrally provided on the oil pump base, and a spindle is provided on the handle, and a spindle push rod passing through the spindle is used to push a piston installed in the oil pump base, so that the reciprocating motion of the piston is used to activate the caliper group to produce a braking effect relative to the wheel. Therefore, the movement stroke of the piston directly affects the speed, sensitivity and effect of the brake. Therefore, when the grip distance of the handle needs to be adjusted, the starting position of the piston needs to be changed by adjusting the spindle push rod. In order to prevent the spindle push rod from moving arbitrarily due to vibration during riding, a locking nut is usually provided. Since the locking nut is located in the rotating actuation area of the handle, it is not easy to operate during adjustment and tools are needed to release and re-tighten it, making it impossible to quickly and conveniently adjust the grip distance.

Furthermore, in the existing brake assembly locked on the handlebar tube, the oil pump base includes a piston group, an oil filling group and a handle, so it has a certain volume ratio and many protruding parts, which invisibly occupies a large space of the handlebar. Moreover, although the existing oil pipe can be designed to be routed inside the handlebar tube, when connecting the oil pump base, it is still necessary to pass the oil pipe connector through the outside of the handlebar tube and connect it to the end of the oil pump base. Therefore, the aforementioned exposed oil pump base and oil pipe connector not only take up space, but also the protruding components will not only affect the smoothness of installation, but also easily hook foreign objects during riding, causing danger.

In other words, the brake group installed on the handlebar tube in the existing hydraulic brake system is large and exposed, which not only takes up a lot of space and destroys the aesthetics, but also makes it inconvenient to adjust the grip distance, which in turn causes safety concerns in use. Therefore, the existing system does need to be further improved, which is also the topic that this creation wants to explore.

Due to the above shortcomings and needs, the creator of this invention has studied the above shortcomings and needs with his many years of experience in related technologies and product design and manufacturing, and actively sought solutions. After continuous efforts in research and trial production, he finally successfully developed a grip adjustment structure for the pressure handle to overcome the troubles caused by the exposed brake group and the inconvenience of grip adjustment in the existing hydraulic brake system.

Therefore, the main purpose of this invention is to provide a brake lever grip distance adjustment structure, so as to conveniently and quickly adjust the brake lever grip distance to meet the different braking force requirements of riders and further enhance driving safety.

In addition, the handle has a corresponding The adjusting screw hole of the extension piece of the adjusting block, and the handle can be supported on the extension piece of the adjusting block by an adjusting bolt screwed on the adjusting screw hole, and the pressing block is pivoted between the handle and the bundle part of the mounting part, and the pressing block is formed with a pull part opposite to the handle and a push part opposite to the piston rod at two ends of the pivot.

Thus, the grip distance adjustment structure of the pressure handle of the invention can utilize the oil pump tube body to be arranged in the handlebar tube, and the pressure block is rotated by the handle to push the piston rod of the oil pump tube body to achieve the braking action. At the same time, the handle has an adjusting bolt that supports the adjusting block, so that the rider can rotate the adjusting bolt clockwise or counterclockwise to press the adjusting block, and can drive the handle away from or close to the handlebar tube to change the different grip distance requirements of the rider. Moreover, the grip distance can be adjusted while riding without using tools, which greatly improves the convenience of grip distance adjustment, effectively improves its practicality, and realizes its economic benefits.

Thereby, a grip distance adjustment structure of the pressure handle which can adjust the grip distance and is easy to operate is formed.

As for the actual operation of the grip distance adjustment structure of the present invention, it is as shown in the first and fourth figures. In operation, when the rider presses the handle (51) of the grip member (50) from the grip release position to the grip brake position close to the handlebar tube (10), the handle (51) can simultaneously actuate the grip block (58) through the adjustment block (55), so that the grip block (58) can push the piston rod (25) of the oil pump tube body (20) from the piston release position to the piston brake position, and the hydraulic oil is transported through the oil pipe (30) to produce a deceleration or braking effect;

As shown in the fifth and sixth figures, since the handle (51) of the pressing handle member (50) uses the adjusting bolt (515) to support the extension piece (551) of the adjusting block (55), when the rider turns the adjusting bolt (515) on the handle (51) of the pressing handle member (50) to press the extension piece (551) of the adjusting block (55), the handle (51) can be driven away from the handlebar tube (10) (as shown in the fifth figure), thereby increasing the handle (51). ), and vice versa, when the rider rotates the adjusting bolt (515) on the handle (51) of the pressure handle member (50) counterclockwise to press the extension piece (551) of the adjusting block (55), the handle (51) can be brought closer to the handlebar tube (10) (as shown in FIG. 6), thereby reducing the grip distance of the handle (51) to meet the rider's different grip distance requirements when braking. Moreover, the grip distance can be adjusted while the rider is riding without using tools, thereby greatly improving the convenience of grip distance adjustment.

Furthermore, when it is necessary to reduce the braking stroke and improve the braking sensitivity, as shown in FIGS. 7 to 10, the variable distance mechanism (60) between the adjusting block (55) of the pressure handle (50) and the pressure block (58) can be used for adjustment;

In a normal state, the first scale (661) of the shifting sleeve (66) of the pitch-changing mechanism (60) corresponds to the reference scale (559) of the braking portion (552) of the adjusting block (55), so that the shifting sleeve (66) can drive the eccentric section (65) of the braking shaft (61) to contact the bearing groove (583) of the lever portion (581) of the pressure block (58) with the lower first contact point (651). At this time, the axis of the pressure block shaft (59) of the pressure block (58) is aligned with the first contact point (651) of the braking shaft (61). ) is 12.1 mm, and the distance from the first contact point (651) of the brake shaft (61) to the axis of the handle shaft (52) of the handle (51) is 19.8 mm (as shown in FIG. 7). When the rider presses the handle (51) by 15 degrees, the adjustment block (55) can drive the pressure block (58) to swing and rotate 27 degrees around the pressure block shaft (59) as the axis, and the push portion (582) of the pressure block (58) pushes the piston rod (25) in the oil pump tube body (20) to move 7.53 mm (as shown in FIG. 8).

During the pitch change operation, the second scale (662) of the shifting sleeve (66) of the pitch change mechanism (60) is made to correspond to the reference scale (559) of the braking portion (552) of the adjustment block (55), so that the shifting sleeve (66) can drive the eccentric section (65) of the braking shaft (61) to contact the bearing groove (583) of the lever portion (581) of the pressure block (58) with the higher second contact point (652). At this time, the distance from the axis of the pressure block shaft (59) of the pressure block (58) to the second contact point (652) of the braking shaft (61) is 11.5 mm, and the second contact point (652) of the braking shaft (61) is 11.5 mm. The distance between the second contact point (652) and the axis of the handle shaft (52) of the handle (51) is 20.8 mm (as shown in FIG. 9). Thus, when the rider presses the handle (51) by 15 degrees, the adjustment block (55) can drive the pressure block (58) to swing and rotate 29.5 degrees around the pressure block shaft (59), and the push portion (582) of the pressure block (58) pushes the piston rod (25) in the oil pump tube (20) to move 8.23 mm (as shown in FIG. 10). This achieves the purpose of changing the braking force of the handle (51), making the braking action more labor-saving and sensitive, and effectively improving the braking effect.

Through the above-mentioned design and description, the invention is applied to the grip adjustment structure of the hidden hydraulic brake group. The oil pump tube (20) can be arranged in the handlebar tube (10), and the pressure handle (50) rotates the pressure block (58) through the handle (51) to push the piston rod (25) of the oil pump tube (20) to achieve the braking action. At the same time, the handle (51) has a function of supporting the adjustment. The adjusting bolt (515) of the block (55) allows the rider to rotate the adjusting bolt (515) clockwise or counterclockwise to press the adjusting block (55), thereby driving the handle (51) away from or close to the handlebar tube (10) to change the different grip distance requirements of the rider. The grip distance can be adjusted while the rider is on the move without using tools, thereby greatly improving the convenience of grip distance adjustment and effectively enhancing its practicality.

From this, we can understand that this creation is a creation with excellent creativity. In addition to effectively solving the problems faced by practitioners, it also greatly improves the efficacy. In the same technical field, there are no identical or similar products created or publicly used. At the same time, it has improved efficacy. Therefore, this creation has met the requirements of "novelty" and "progressiveness" for new patents, and an application for a new patent is filed in accordance with the law.
