Technical Field

[0001] The utility model relates to the technical field of vehicle auxiliary parking, in particular to an auxiliary parking device for a loader. Background Art

[0002] A loader is a special vehicle widely used in earthwork construction projects. It has the advantages of fast operating speed, high efficiency, good maneuverability, and easy operation. It is mainly used for shoveling soil, sand and gravel, and can also be used for light snow shoveling. It is an indispensable engineering machinery in projects such as water conservancy, national defense, road construction and infrastructure. After the vehicle is moving, it is necessary to park the vehicle. In the existing loader, during the parking process, usually when the vehicle is parked, the driver of the vehicle needs to tighten the parking brake valve. Under the action of the brake spring, the vehicle parking brake is achieved. When the vehicle driver forgets to pull the handbrake valve or the brake valve is not pulled in place, it is easy to cause the vehicle parking brake to be not in place, resulting in the vehicle slipping and an accident. Therefore, we have proposed a loader auxiliary parking device to solve the above-mentioned problems. Utility Model Content

When the driver is in the driving seat of the vehicle and the person is detected by the infrared human body sensor, the electromagnetic air valve is energized and the original vehicle parking brake pipeline is connected. The driver can operate the vehicle's driving or braking according to needs without affecting the normal use of the vehicle. The structure is simple, the cost is low, and it is easy to implement.
