Brake armrest and assembly method for power-assisted tricycle

Abstract

The invention discloses a motor tricycle brake handrail and an assembling method thereof. The motor tricycle brake handrail comprises a handrail body of the structure of a cover body composed of an inner side cover and an outer side cover. The inner side cover and the outer side cover are assembled through a positioning mechanism and a connecting mechanism. A hollow handle window is arranged at the front end of the cover body. A handle track groove is formed in the position, at the handle window and the handle portion, of the inner side cover and the outer side cover. A handle mechanism and a control mechanism used in cooperation with the handle mechanism are arranged inside the cover body. Brake cables led from the handle mechanisms of the left handrail and the right handrail are connected with a brake and a gearbox lifting lever respectively. The handrail is connected with a seat through a handrail fixing tube. The motor tricycle brake handrail is simple in structure and reasonable in structure, hand brake braking and high-low-speed gear conversion and the handrail are arranged into a whole, and the using function of the seat handrails is added; during operation, the corresponding functions can be achieved only by lifting the handle portion by the left hand or the right hand and moving a safety catch back and forth, no bending operation is needed, operation is quite convenient, using is safe, the manufacturing cost is low, and application and popularization are convenient.

[0002] Braking and shifting systems are essential equipment for vehicles. At present, hand brakes are commonly used in vehicles on the market, such as: patent number 201310088370.X, electric tricycle hand brake device, patent number 201410200013.9, a hand brake for automobiles The device, the patent number is 201410379292.8, a kind of automobile hand brake assembly, the patent number is 201410378932.8, a kind of automobile hand brake, the patent number is 201120406553.7, it is used for the hand brake control mechanism of the forklift, its structure principle is similar, and its pawls are all It is set on the handle part, and the ratchets are all external teeth, set with the brake line guide part, and together with the handle as a combined part of relative movement, its structure and process are complicated, and the production cost is high. There is also a patent number 201220439786.1, The single gear shifter of the vehicle, and the manual brakes of electric and motorized tricycles are mostly set on the left and right side beams of the tricycle. The operation requires a large bending action, and a small part is placed above the sides of the bucket, which not only costs a lot , it is also very inconvenient to use and operate, and it is very dangerous
