Description

Technical Field

[0001] The utility model relates to the field of motorcycle brake system parts, in particular to a motorcycle direct-push upper pump structure. Background Art

[0002] The motorcycle brake handle includes a pump body and a handle. A piston is provided at one end of the pump body facing the handle. A piston push rod is provided between the pump body and the handle, with one end abutting against the piston and the other end connected to the handle. During assembly, it is necessary to ensure that the piston push rod is always kept in a vertical state with the piston during the braking operation to ensure a good braking effect and the service life of the piston. If there is a deviation in the precision of the piston push rod during processing or there is a deviation in the drilling of the connection hole reserved for the piston push rod on the handle, it is difficult to ensure the verticality between the piston push rod and the piston, resulting in a decrease in the service life of the piston push rod and the piston. Therefore, if the patent number is CN 208715399 U's utility model patent discloses a motorcycle direct push upper pump piston push rod connection structure, which adopts a pump body including a handle and one end hinged to the handle, the pump body is provided with a piston accommodating cavity with one end open at one end facing the handle, and a piston is arranged in the piston accommodating cavity, the handle includes a gripping portion and an operating portion connected to the gripping portion, and is characterized in that: a joint portion is provided at one end of the operating portion close to the pump body, the handle is hinged to the pump body through the joint portion, and an adaptive piston push rod mechanism is arranged between the pump body and the handle;

[0003] The invention solves such problems by using an adaptive piston push rod mechanism. However, the position design of the adaptive piston push rod structure requires that the grip adjustment device (the specific structure of the grip adjustment device can be referred to in the patent number: CN 214729423 U disclosed grip-adjustable brake handle) provided on the existing brake handle needs to be designed to another place, which makes the design inconvenient and easily leads to the problem of complex structure. The brake handle in the prior art generally has a power-off switch (the reason for setting the power-off switch is " The existing brake handle includes a thrust block, which is matched with the oil pump plunger. When the vehicle needs to stop, the external force gives the brake handle a gripping force, and the brake handle rotates along the fixed installation position of the handle. At this time, the normally closed pressure block of the power switch is separated from the power switch, and the power circuit of the vehicle is cut off, and the power is cut off to complete the first step of braking; at the same time, the gripping force is converted into a thrust block to give an inward clamping force to the upper pump plunger, and the hydraulic oil in the upper pump is transported to the lower pump through the oil pipe. The piston in the lower pump is subjected to the pressure of the hydraulic oil, moves and drives the brake pad to give the wheel braking force to complete the braking operation. "Reference patent number: CN 104494770A a brake handle), after the brake handle has more and more functions, its design and the rationality of the arrangement of parts become very important, and the difficulty of assembly must also be considered. It is necessary to improve such situations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

The relay block is coaxially arranged with the hinge axis of the handle and the pump body. When the handle performs braking operation along the hinge, it can also drive the relay block to move without affecting the braking operation. When a certain area of ​​the relay block is worn, only the relay block needs to be replaced without replacing other parts.

[0011] By adopting the above technical solution, the connection hole of the pressure push block can be set as a countersunk hole. After the relay block is connected by a fastener, the fastener can be locked into the countersunk hole to improve the aesthetics. On the other hand, pressure push blocks of different models and specifications can be connected to improve the versatility of the relay block.

The adjustment knob is connected to the operating part through a threaded connection hole set on the operating part. The grip distance can be adjusted by changing the length of one end of the adjustment knob exposed through the threaded connection hole, which is convenient for adjustment.

[0018] The above-mentioned motorcycle direct-push upper pump structure can be further configured as follows: a mounting ring groove coaxially arranged with the mounting hole is provided in the middle part of the relay block, a reset torsion spring is installed in the mounting ring groove, one end of the reset torsion spring passes through the mounting ring groove and extends outward to form a first reset end, and the other end extends outward to form a second reset end, a first reset end accommodating groove connected to the mounting ring groove is provided on one side of the mounting ring groove, the first reset end is arranged in the first reset end accommodating groove, the operating part is provided with a second reset end clamping hole, and the second reset end is clamped in the second reset end clamping hole.

[0032] By adopting the above technical scheme, in order to realize the three functions on one handle at the same time in the prior art, many complicated structures need to be designed. The utility model installs a relay structure in the operating part of the handle, and the grip distance is adjusted by the relay structure and the grip distance adjustment device.
