Abstract

An apparatus capable of automatically pulling a parking brake fully comprises a sensing module (1), a control module (2), and an execution module (3). The sensing module (1) is used to determine, by means of sensing, whether a driver has exited a vehicle. The execution module (3) is connected to a parking brake lever, and is used to drive the parking brake lever to rotate so as to perform braking. An initial position of the execution module (3) is a position in which the parking brake is not fully pulled.

An automatic tensioning handbrake device, combined with FIG. 1 and FIG. 2, includes: an induction module 1, a control module 2 and an execution module 3.

The sensing module 1 is used to sense whether the main driver gets off the vehicle, and its sensing mode can be set to sense the driver's position, the main driver's seat belt plugging or unplugging, or whether the main driver's door is open.

Execution module 3 is connected with the handbrake lever to drive the handbrake lever to rotate and brake. The initial position of the execution module 3 is the unbrake position of the handbrake. When the execution module 3 is running, the handbrake lever is rotated to achieve braking. In the execution module 3, the handbrake is pushed to When the brake is in the locked position, the automatic locking device of the car's handbrake can lock the handbrake to the locked state. After the brake is completed, the execution module 3 will automatically detach from the handbrake lever and return to the starting position. The driver can manually loosen the handbrake when driving the car again. Convenience.

The control module 2 is connected to the induction module 1, and controls the start and stop of the execution module 3 according to the signal of the induction module 1. The control module 2 includes a controller 21 and a delay disconnection relay 22 connected to the controller 21. The delay disconnection relay The normally open switch in 22 is connected between the power supply terminal and the execution module 3. The controller 21 sends a power-on command to the delayed disconnection relay 22 after receiving the main driving position returned by the sensor module 1 after getting off the vehicle. At this time, the execution module 3 starts the operation of tightening the handbrake, and the delay time of the delayed disconnection relay 22 is set to the time of one cycle from the starting position of the execution module 3 to the restoration starting position, that is, the delay disconnection The relay 22 disconnects the power supply of the execution module 3 after the execution module 3 completes a braking action and returns to the initial position, so as to avoid the execution module 3 from performing multiple meaningless operations.

The execution module 3 includes a driving rod 32 and an electric push rod 31. The driving rod 32 is fixedly connected with the handbrake rod and is located on the extension line of the handbrake rod near the hinge shaft of the handbrake rod.

Example two

The difference between this embodiment and the first embodiment is that the installation position of the sensing module 1 is different.

Sensing module 1 uses a pressure sensor and is installed inside the main driving seat belt socket. When the pressure inside the main driving seat belt socket is zero, it can be confirmed that the main driving seat belt has been pulled out. At this time, the controller 21 sends an operation instruction to the execution module 3 to achieve Automatically tighten the handbrake function.

The automatic tensioning handbrake device in the embodiment of the present invention can not only automatically tension the handbrake and improve parking safety, but also remind the driver to wear a seat belt before driving, so as to improve driving safety.

Example three

The difference between this embodiment and the first embodiment is that the sensing module 1 and its installation position are different.

In this embodiment, the sensing module 1 adopts a displacement sensor, which is set at the door lock position of the main driving door and is used to detect whether the main driving door lock is open or whether the main driving door is open;

As a detection method, the sensor module 1 detects whether the door lock of the car door is opened. When the door lock of the car door is opened, it can be determined that the driver is about to get off or the driver is not ready to drive the vehicle. At this time, the controller 21 controls the execution Module 3 tightens the handbrake to improve parking safety.

As another detection method, the sensor module 1 detects whether the car door is open. When the car door is opened, it can be determined that the driver is getting on and off the car. At this time, the controller 21 can also control the execution module 3 to tighten the hand brake to improve parking safety.

Example four

The sensing module 1 is a through-beam photoelectric sensor. The emitter and receiver of the through-beam photoelectric sensor are respectively installed on the backrest of the main driver’s seat and on the console in front of the main driver to detect whether there is a person in the main driving position. When there is no person in the driving position, the controller 21 controls the execution module 3 to perform the operation of applying the hand brake.

Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made on the basis of the present invention, which is obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention belong to the scope of the present invention.
