Abstract

The invention relates to a hand brake device of an electric car. A right brake handle of the electric car is substituted by a double-handle hand brake; two wire cables maintain in connection with a front brake and a rear brake, and another wire cable is connected with balance wheels on both sides; an elevating wheel handle is additionally arranged on the right side of a holding handle and is also connected with the balance wheels on both sides; and a middle supporting tube of the car is additionally provided with a sliding bracket through which two upgoing wire cables and four downgoing branched wire cables are together connected with the balance wheels on both sides. The hand brake device assembly also comprises two sets of bilaterally symmetrical pulling devices and driving devices which are installed on rear wheel axles on both sides of the electric car. When the right brake handle and the elevating wheel handle are operated, the sliding bracket is connected with the wire cables, an upper pressure spring pull rod and a lower pressure spring pull rod of each pulling device are connected through the branched wire cables so as to link an upper wing swing handle and a lower wing swing handle, and a moving swing in each driving device rotates to drive the balance wheels to rise and fall.

Description

Technical field [0001] The invention relates to a handbrake device for an electric vehicle, in particular to a handbrake type balancing device which uses a handle to control the lifting and lowering of two small wheels to achieve balance. Background technique [0002] Under the prior art, there is a kind of automatic wheel-changing vehicle, and a kind of bicycle fixed wheel, the former kind of structure is complex and heavy, and the wheel conversion is limited, and the latter kind of structure is simple but inconvenient to use. Contents of the invention [0003] The present invention aims at the above disadvantages, and designs a handbrake device for an electric vehicle, which can overcome the above disadvantages. It can freely adjust the small wheels, is particularly convenient to use, and can maintain the original functions of the electric vehicle. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] 1. The right ...
