The invention discloses a parking mechanism of an electric sightseeing vehicle. The parking mechanism comprises a pedal, a brake, a ratchet wheel, a pawl, a front brake pull rope, a balance frame, a first rear brake pull rope and a second rear brake pull rope. One end of the first rear brake pull rope and one end of the second rear brake pull rope are in transmission connection with the brake. Thepedal drives the ratchet wheel to rotate; when the pedal is located at the parking position, the ratchet wheel is self-locked by the pawl; when the pedal is lower than the parking position, the ratchet wheel is automatically unlocked by the pawl; according to the invention, the foot brake is used for replacing the traditional hand brake; the input force of the parking brake system can be increased to 500-600N from 100-150N of a hand brake; moreover, the occupied space is not obviously increased on the vehicle, and the lever ratio of the parking system can be correspondingly reduced a lot dueto the increase of input force nowadays so that the requirement of the parking system on the travel space is reduced, the rigidity of the parking system is obviously improved, and the working reliability of the parking system is improved.

    本发明公开了一种电动观光车的驻车机构,其包括踏板、制动器、棘轮、棘爪、前制动拉绳、平衡架、第一后制动拉绳和第二后制动拉绳;第一后制动拉绳和第二后制动拉绳的一端分别与制动器传动连接,所述踏板带动棘轮作旋转运动,所述踏板位于驻车位置时棘爪对棘轮进行自锁,所述踏板低于驻车位置时棘爪对棘轮自动解锁,本发明通过使用脚刹代替传统的手刹,驻车制动系统的输入力可以由手刹的100~150N增加到500~600N,而且本发明在车辆上并没有明显增加占用空间,而由于如今输入力的增加,驻车系统杠杆比可以相应地减小很多,减少了驻车系统对行程空间的要求,从而明显增加了驻车系统的刚度,提高了驻车系统工作的可靠性。
