[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-5An integrated hydraulic power-off brake handle shown in the figure includes a handbrake 1 and an oil brake component 2, an annular hole is opened inside the oil brake component 2, a piston rod 201 is installed in the annular hole, the end of the piston rod 201 away from the annular hole is threadedly sleeved with one end of the handbrake 1, a hydraulic device 202 is arranged at the top of the oil brake component 2, and a cover-tube integrated part 3 is arranged on the top of the hydraulic device 202, and the cover-tube integrated part 3 includes: an oil sealing cover 301, the bottom of the oil sealing cover 301 is sleeved with the top of the oil pressure device 202; a power supply tube 302, the power supply tube 302 is integrally arranged at the bottom of the oil sealing cover 301, and the power supply tube 302 is used for vehicle power on-off control.

[0025] It should be noted that the end of the handbrake 1 close to the piston rod 201 is hinged to the inner wall of one end of the oil brake component 2, a fixing clamp 4 for connecting to the handlebar is provided on one side of the oil brake component 2, and a line system 5 is provided at the bottom of the oil brake component 2.

[0026] Specifically, the bottoms of both sides of the handbrake 1 are rotatably connected to one side of the oil brake component 2 , and a fixing clip 4 is provided on the other side of the oil brake component 2 .

[0027] It should be noted that the design of the fixing clamp 4 is based on the clamp body of model automatic 75522943837. It is tough, strong and durable, and is installed separately up and down. It is wrapped with a rubber ring at the fixed position to increase the sliding friction of the surface. The fixing clamp 4 is attached to the surface of the rubber ring and installed with screws. Since the rubber ring is added inside, the rubber ring will fit the handle more closely when the fixing clamp 4 is tightened. The corresponding friction force increases with the increase in stress, which plays a role of anti-slip and stability. It can be adjusted appropriately according to the position of the handle.

[0028] Specifically, the line system 5 includes:

[0029] A piston cover 501, the top of the piston cover 501 is sleeved with the bottom of the oil brake component 2;

[0030] Brake line 502, one end of the brake line 502 is inserted and connected to the middle of the piston cover 501, and is connected to the bottom of the oil pressure device 202. The line system 5 also includes a power line 503, one end of the power line 503 is inserted and connected to the middle of the power tube 302, and the power line 503 is electrically connected to the inserted end of the power tube 302. A connecting groove is opened on the top of the oil pressure device 202, and the end of the piston rod 201 away from the handbrake 1 is rotated and inserted and connected in the connecting groove.

[0031] It should be noted that the piston cover 501 is sleeved on the bottom of the oil brake component 2. The bottom of the piston cover 501 is a hole that is connected to the oil brake component 2. A brake line 502 is arranged in the hole, which can well seal the oil brake component 2 to the oil pressure device 202. At the same time, it also protects the head of the brake line 502 from damage. When the handbrake 1 is squeezed, the handbrake 1 drives the piston rod 201 to advance in the hole. When the piston rod 201 is pushed, the oil pressure is increased, and the brake line 502 starts to operate, increasing the oil pressure for braking. The design of the power cord 503 refers to the model JL-F-Z209AG wire. The use of this model of waterproof wire has sensitive power-on effect and stable performance.

[0032] Working principle of this utility model:

[0033] During actual assembly, the handbrake 1 and the oil brake component 2 are completely connected, the top of the piston rod 201 is connected to the bottom of the handbrake 1 through a threaded sleeve, and the position of the handbrake 1 and the handle is adjusted to a comfortable position according to the length of the finger. The oil brake component 2 is placed above the handle and tightly fixed to the lower fixing frame through threads. An appropriate amount of oil is added to the oil pressure device 202, and the cover tube integral part 3 is aligned with the upper sleeve connection of the oil pressure device 202. The two components are firmly installed through threads, and then the brake line 502 at the bottom is connected to the power line 503. The handbrake 1 is squeezed, and the handbrake 1 pushes the piston rod 201 to push forward, generating a pressure difference. The brake line 502 is pulled and contracted under the action of pressure, so that the brake line 502 pulls the brake block to rub against the tire, thereby utilizing friction to decelerate, and the power tube 302 starts to cut off the power while the handbrake 1 is squeezed.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
