Mechanical vehicle cruise control device

Abstract

The invention discloses a mechanical vehicle cruise control device. The mechanical vehicle cruise control device comprises an execution mechanism, a locking mechanism, unlocking mechanism, an emergency unlocking mechanism; the execution mechanism is connected with an accelerator pedal rod by use of a rotating shaft; the locking mechanism is connected with the execution mechanism by use of a locking pull wire, and used for controlling the locking action of the execution mechanism by tightening the locking pull wire; the unlocking mechanism is fixed on a brake pedal arm and connected with the locking mechanism by use of an unlocking pull wire, and the unlocking mechanism is used for controlling the locking mechanism to release the locking pull wire so that the execution mechanism is enabled to execute an unlocking action; the emergency unlocking mechanism is arranged on the locking pull wire and used for releasing the locking pull wire in case of the failure of the unlocking mechanism. The mechanical vehicle cruise control device is capable of realizing the vehicle cruise control function by use of the simple mechanism structure; the problems of complex structure and relatively high cost of an electronic cruise control system are solved, and as a result, the cruise control of ordinary level vehicles also can be realized without increasing the cost greatly.

Description

technical field [0001] The invention relates to a vehicle constant speed cruise device, in particular to a mechanical vehicle constant speed cruise device. Background technique [0002] At present, the cruise control system used by vehicles is generally electronic. Its principle is to control acceleration, braking, clutch, gear, etc. through the actuator according to the vehicle speed feedback signal, so that the vehicle can run at a constant speed at a given speed. The electronic cruise control system reduces the driver's driving fatigue under certain road conditions to a certain extent. But because the structure of the electronic cruise control system is complex and the cost is high, it is usually only used in high-end cars, and the low-cost mechanical vehicle cruise control device has not yet been seen in relevant reports. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical vehicle cruise control device with simple structu...
