Description

Vertical hydraulic brake assembly attachment structure

This invention belongs to the field of hydraulic brake assembly technology. Specifically, it is a vertical hydraulic brake assembly attachment structure, which can increase the assembly overlap distance and effectively improve the joint strength to avoid breakage and damage due to improper collision. At the same time, it can simplify the configuration and reduce its occupancy on the handlebar tube.

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. For the brake system of the above-mentioned vehicles, it has developed from the traditional cable-driven operation method of the caliper to the operation method of using a pressure handle to push the hydraulic oil, so that the hydraulic oil in the oil circuit pushes 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 clamp device installed on the frame. The brake group is mainly a horizontal structure slightly parallel to the handlebar tube. The hydraulic pump body of the existing brake group locked on the handlebar tube includes a piston group, an oil replenishing group and a pressure handle. Therefore, it has a certain volume ratio and invisibly occupies a large space on the handlebar tube. Although some oil pipes can be designed to be routed inside the handlebar tube, when connecting the oil pressure pump body, the oil pipe connector still needs to be passed through the outside of the handlebar tube and connected to the end of the oil pressure pump body. Therefore, the aforementioned exposed oil pressure pump body 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 get caught by foreign objects during riding, causing danger.

To this end, the industry has currently developed a vertical brake assembly, which simplifies the accessories on the handlebar tube and reduces the size by setting a vertical pump body at the end of the handlebar tube, such as Taiwan Patent I796209 and China Patent CN219790430U. However, they have problems such as insufficient assembly strength and excessive protrusion of the vertical pump. When the vehicle body accidentally overturns, it is easy to break at the joint due to collision.

In other words, the existing vertical hydraulic brake assembly has insufficient joint strength or the vertical pump is too protruding due to its imperfect design, causing unnecessary losses and safety concerns in use. Therefore, the existing ones do need further improvement, which is also the topic that this creation wants to explore.

Due to the above-mentioned shortcomings and needs, the creator has used his many years of experience in related technologies and product design and manufacturing to study the above shortcomings and needs, and actively seek solutions. After continuous efforts in research and trial production, he finally successfully developed a vertical hydraulic brake assembly attachment structure to overcome the inconvenience and trouble caused by the existing hydraulic brake assembly being assembled on the handlebar tube.

Therefore, the main purpose of this invention is to provide a vertical hydraulic brake assembly attachment structure, so as to increase the assembly overlap distance and diameter, effectively improve the joint strength, avoid breakage and damage due to improper collision, and effectively extend its service life.

In addition, the second main purpose of the present invention is to provide a vertical hydraulic brake brake group attachment structure, which can reduce the volume of the hydraulic brake group without affecting the hydraulic brake stroke, can effectively reduce the protrusion of the handlebar tube surface, avoid danger caused by hooking foreign objects during riding, and improve its practicality.

Based on this, this invention mainly realizes the aforementioned purpose and its effect through the following technical means, which is applied to a handlebar tube and connected to an oil pipe inserted into the handlebar tube. The vertical hydraulic brake assembly attachment structure includes:

A hydraulic pump body, which has a piston chamber inside, and a piston supported by an elastic member is slidably disposed inside the piston chamber, the hydraulic pump body having an inner surface corresponding to the handlebar tube and an outer surface corresponding to the outside, wherein the inner surface is formed with an overlapping inner concave portion corresponding to the handlebar tube, so that an overlapping end portion of the handlebar tube can be locked in the overlapping inner concave portion of the hydraulic pump body;

A pressure handle is pivotally arranged at one end of the hydraulic pump body different from the handlebar tube, and the pressure handle extends in the same direction as the handlebar tube. A push rod capable of pushing the piston in the piston chamber is pivotally arranged on the pressure handle.

Thus, the vertical hydraulic brake assembly attachment structure of the invention can utilize the overlapping inner concave portion formed on the inner surface of the hydraulic pump body, and cooperate with the equal-diameter overlapping end design of the handlebar tube, so that the handlebar tube can be connected to the overlapping inner concave portion of the hydraulic pump body without changing the outer diameter to ensure its stress resistance strength, thereby increasing the assembly overlapping distance and diameter, effectively improving the joint strength, avoiding breakage and damage due to improper collision, effectively extending its service life, greatly improving its practicality, and realizing its economic benefits.

As shown in the second, third and fourth figures, the hydraulic pump body (10) has an inner surface (101) corresponding to the overlapping end (51) of the handlebar tube (50) and an outer surface (102) corresponding to the outside. The hydraulic pump body (10) has a piston chamber (11) inside [as shown in the third figure], and a piston (13) supported by an elastic member (12) is slidably provided inside the piston chamber (11) for using the piston (13) to push the hydraulic oil in the piston chamber (11). The hydraulic pump body (10) has a corresponding handlebar tube (50) formed on the inner surface (101). A stacking inner recess (14) of the stacking end (51) enables the handlebar tube (50) to be connected to the stacking inner recess (14) of the hydraulic pump body (10) without changing its outer diameter, so as to ensure its stress resistance strength. In addition, the hydraulic pump body (10) is provided with an oil pipe joint seat (15) corresponding to the interior of the handlebar tube (50) and connected to the piston chamber (11) within the range of the stacking inner recess (14). The oil pipe joint seat (15) can be selectively connected to a locking joint (65) of the oil pipe (60), so that the oil pipe (60) can be completely hidden and arranged inside the handlebar tube (50);

Furthermore, the hydraulic pump body (10) is formed with a semicircular mounting groove (16) at the side edge of the opening of the overlapping inner concave portion (14) for cooperating with a corresponding semicircular tube cover (17) to jointly lock the handlebar tube (50), wherein the semicircular mounting groove (16) of the hydraulic pump body (10) and the semicircular tube cover (17) are formed with an axis at one end opposite to the semicircular tube cover (17). A first pivot (161) and a second pivot (171) are parallel to the axis of the handlebar tube (50) and can be mutually pivoted, so that the semicircular tube cover (17) can be pivoted at the opposite semicircular mounting groove (16) of the hydraulic pump body (10) by using a pivot rod (173). 6) A first locking hole (162) and a first countersunk hole (172) are formed at the other opposite end of the semicircular tube cover (17), the axis of which is perpendicular to the axis of the handlebar tube (50) and can be fitted with each other, so that the semicircular tube cover (17) can be locked to the opposite semicircular mounting groove (16) of the hydraulic pump body (10) by a locking piece (174), so that the hydraulic pump body (10) can be selectively and effectively tightened to the overlapping end (51) of the handlebar tube (50) (as shown in the third and fourth figures), and the hydraulic pump body (10) has a hinge part (18) at one end different from the oil pipe joint seat (15), so that the pressing handle member (30) can be pivoted by a main pivot (19);

The end of the pressure handle (30) has a pivot portion (31) that can be clamped on the pivot ear portion (18) of the hydraulic pump body (10), so that the pressure handle (30) can be pivoted to the end of the hydraulic pump body (10) by using the main pivot (19), and at the same time, the free end of the pressure handle (30) and the handlebar tube (50) extend in the same direction, so that the pressure handle (30) can be freely moved. The end of the pressure handle (30) can be pivoted between a braking position and a release position. The pressure handle (30) has a core shaft hole (32) corresponding to the piston chamber (11) of the hydraulic pump body (10), and a push rod core shaft (33) is pivotally arranged on the pressure handle (30). The push rod core shaft (33) is provided with a push rod extending toward the piston chamber (11) of the hydraulic pump body (10). The push rod (35) can push against the piston (13) in the piston chamber (11), so that when the pressure handle (30) is pressed to the braking position, the pressure handle (30) can push the piston (13) of the hydraulic pump body (10) through the push rod (35) to compress the elastic member (12), and press the hydraulic oil in the hydraulic pump body (10) into the brake. A braking action is generated in the oil pipe (60), and when the pressure handle (30) is released to the release position, the piston (13) can be pushed by the elastic member (12) to push the push rod (35) to actuate the pressure handle (30) to reset, and allow the hydraulic oil to enter the piston chamber (11) again for the next braking application, thereby completing the action of releasing the brake.

According to certain embodiments, a further feature of the invention is that the axis of the handlebar tube (50) is defined as a tube body long axis (L1), and the long axis of the hydraulic pump body (10) passing through the axis of the main pivot (19) and perpendicular to the tube body long axis (L1) is defined as a pump body long axis (L2), and the axis in the piston chamber (11) for the piston (13) to actuate is defined as a chamber long axis (L3), wherein the The pump body long axis (L2) is located outside the overlapped end portion (51) of the handlebar tube (50), and the chamber long axis (L3) is located between the pump body long axis (L2) and the tube body long axis (L1), and the chamber long axis (L3) and the tube body long axis (L1) are in an acute angle, wherein the acute angle between the chamber long axis (L3) and the tube body long axis (L1) is 65 degrees to 85 degrees, and the preferred angle is 75 degrees to 80 degrees. The piston chamber (11) of the hydraulic pump body (10) is tilted so that a longer braking stroke of the piston chamber (11) can be obtained under the same length of the hydraulic pump body (10), or the volume of the hydraulic pump body (10) can be reduced under the same braking stroke of the piston chamber (11), and the overlapping inner concave portion (14) of the hydraulic pump body (10) can be formed inwardly with a deeper concave surface (141 ) and a shallower concave surface (142), and at the same time, the overlapping end portion (51) of the handlebar tube (50) forms a corresponding higher end surface (511) and a lower end surface (512), so as to increase the connection length between the overlapping inner concave portion (14) of the hydraulic pump body (10) and the overlapping end portion (51) of the handlebar tube (50), further increase the locking area of the semicircular tube cover (17), and thus improve the locking strength.

Furthermore, according to certain embodiments, as shown in FIG. 5 , the semicircular mounting groove (16) of the hydraulic pump body (10) and the semicircular tube cover (17) are respectively formed with a second locking hole (165) and a second countersunk hole (175) whose axes are perpendicular to the axis of the handlebar tube (50) and can fit together, so that the semicircular tube cover (17) can be respectively covered and locked to the corresponding semicircular mounting groove (16) of the hydraulic pump body (10) by a locking piece (174), so as to selectively and effectively tighten the hydraulic pump body (10) to the overlapping end (51) of the handlebar tube (50).

Through the above-mentioned design and description, the present invention uses the inner surface (101) of the hydraulic pump body (10) to form the overlapping inner concave portion (14), and cooperates with the design of the equal-diameter overlapping end portion (51) of the handlebar tube (50), so that the handlebar tube (50) can be connected to the overlapping inner concave portion (14) of the hydraulic pump body (10) without changing the outer diameter, so as to ensure its stress resistance strength, thereby increasing the assembly overlapping distance and diameter, effectively improving the joint strength, avoiding fracture and damage due to improper collision, and effectively extending its service life. At the same time, the piston chamber (11) of the hydraulic pump body (10) is formed at a sharp angle to the handlebar tube (50). The inclined arrangement of the hydraulic pump body (10) can not only free up space for the overlapping inner recess (14), but also reduce the volume of the hydraulic pump body (10) without affecting the braking stroke of the piston (13) in the piston chamber (11) activated by the pressure handle (30), and optimize the configuration space of the hydraulic pump body (10). At the same time, it can effectively reduce the protrusion of the handlebar tube (50) surface to avoid the danger caused by hooking foreign objects during riding, thereby improving its safety. At the same time, the oil pipe (60) can be directly placed on the handlebar tube (50), not only will it not be bent, but it can also be directly and completely hidden inside the handlebar tube (50), further facilitating installation and assembly, thereby improving its practicality.
