[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:
At first please refer to shown in Fig. 1-2, old man of the present utility model helps the embodiment of step car brake control structure, allows user remove brake with one-handed performance.This utility model comprises and helps step vehicle frame 10, a brake device 2, a drive rod 3, a moving part 4 and a keeper 5 to connect and compose.
Wherein help step vehicle frame 10, include a deployed condition (shown in the 1st, 2 figure) and a folding state (figure does not show), this helps step vehicle frame 10 to include wheels 11, these wheels 11 devices are in foot pipe 12 lower ends, to provide user to promote, help step vehicle frame 10 further to comprise hand push frame 13, grip promotion for user and help step vehicle frame 10, these hand push frame 13 its both sides are fixed with pin joint seat 14 respectively.
Brake device 2, be device wheels 11 or foot pipe 12 lower ends, include a handbrake lever 21 and an elastic parts 22, in the middle of present embodiment, this handbrake lever 21 is rotating wheels 11 or foot pipe 12 lower ends of being articulated in, and this handbrake lever 21 includes a brake portion 211, relies on the rotation of handbrake lever 21 to press wheel 15 tyre surfaces by this brake portion 211, in order to do wheel 15 can't be rotated again, reach the effect of brake by this; In addition, also can make wheel 15 extend the brake tooth, rely on the clip of 21 pairs of brakes of handbrake lever tooth, rotate, with the effect (figure does not show) that reaches brake to stop wheel 15; In addition, in the middle of this enforcement, this elastic parts 22 is an extension spring, this elastic parts 22 is that device is between the wheels 11 or foot pipe 12 of handbrake lever 21, this elastic parts 22 can be when handbrake lever 21 be rotated, and auxiliary brake portion 211 separating wheels, 15 tyre surfaces are to remove the brake state.
