Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mechanical garages, and more specifically, to a device for detecting whether a vehicle is parked in place and whether there is a vehicle on a vehicle loading plate in a mechanical garage. Background Art
[0002] The common vehicle presence detection device in mechanical garages on the market is a pair of diagonal photoelectric switches installed on the diagonal of the vehicle loading plate. The device is a photoelectric detection device with a high probability of false triggering. For example, if a person stands in the middle of the vehicle plate or the vehicle has not fully entered the vehicle loading plate, the detection device will be triggered as long as the diagonal line is blocked. The common vehicle arrival detection device on the market is 2 to 3 sets of photoelectric switches to detect the wheel position. They are installed close to the ground. The mirror of the photoelectric switch is easily dusty and causes false triggering. The detection is not accurate, the circuit is complex, and the cost is high.
[0003] In view of this, we propose a device for detecting whether a vehicle is parked in place and whether there is a vehicle on a vehicle loading plate in a mechanical garage. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] The purpose of the present application is to provide a device for detecting whether a car is parked in place and whether there is a car on a loading plate in a mechanical garage, which solves the technical problems in the above-mentioned background technology and achieves the technical effects of not being easily triggered by mistake, accurate detection, simple circuit and low cost.
[0006] 2. Technical solution
[0007] The technical solution of the present application provides a device for detecting whether a car is parked in place and whether there is a car on a loading plate in a mechanical garage, comprising a rear wheel stopper rod and a front wheel stopper fixed on the loading plate, wherein the rear wheel stopper rod is fixed to the end of the loading plate, and the front wheel stopper is rotatably connected to a side of the rear wheel stopper close to the rear wheel stopper rod, and the L-shaped pressure plate is also elastically connected to the front wheel stopper, and a proximity switch is fixedly installed on the side of the loading plate close to the L-shaped pressure plate.
[0008] By adopting the above technical solution, the right end of the vehicle loading plate is the entrance and exit end, and the left end is the terminal end. When a car drives into the vehicle loading plate, the wheels pass the front wheel stop and roll over the L-shaped pressure plate. The L-shaped pressure plate rotates downward, and the left end of the L-shaped pressure plate is pressed down and close to the proximity switch. The proximity switch sends a signal to the mechanical garage control system, indicating that there is a vehicle on the vehicle loading plate and it has been parked in place; when the car drives out of the vehicle loading plate, the L-shaped pressure plate rebounds to the upper limit position of the lower edge of the rear wheel stop rod under the action of the elastic rebound force, and the proximity switch is reset, indicating that there is no vehicle on the vehicle loading plate.
[0009] As an optional solution of the technical solution of this application document, a plurality of spring hinges are fixedly installed between the L-shaped pressure plate and the front wheel stop.
[0010] By adopting the above technical solution, the right end of the L-shaped pressure plate is fixed to the left side of the front wheel stop by a spring hinge, and when the L-shaped pressure plate is not crushed by the wheel, the spring hinge causes the L-shaped pressure plate to tilt up.
[0011] As an optional solution of the technical solution of this application document, the rear wheel stopper is fixed to the upper edge of the vehicle loading plate, and the front wheel stopper is a V-shaped steel.
[0012] By adopting the above technical solution, the rear wheel stopper is fixed to the upper edge of the vehicle loading plate. Firstly, it can prevent the wheel from rolling over the proximity switch after running over the rear wheel stopper. Secondly, the L-shaped pressure plate rebounds to the upper limit position of the lower edge of the rear wheel stopper under the action of elastic rebound force to limit the position. The V-shaped structure of the front wheel stop is conducive to the passing of the wheel.
[0013] As an optional solution of the technical solution of the present application document, the proximity switch is electrically connected to an audible and visual alarm placed at the entrance and exit of the vehicle loading plate.
[0014] By adopting the above technical solution, when the left end of the L-shaped pressure plate is pressed down and close to the proximity switch, the proximity switch sends a signal to the mechanical garage control system, so that the sound and light alarm is energized, prompting the driver that the vehicle has stopped and is in place.

[0021] The present application is further described in detail below in conjunction with the accompanying drawings.
[0022] A device for detecting whether a vehicle is parked in place and whether there is a vehicle on a vehicle loading plate in a mechanical garage, comprising a rear wheel stopper rod 6 and a front wheel stopper 5 fixed on the vehicle loading plate 4, the rear wheel stopper rod 6 being fixed to the end of the vehicle loading plate 4, the front wheel stopper 5 being rotatably connected to a side of the rear wheel stopper rod 6 close to the rear wheel stopper rod 6, the L-shaped pressure plate 1 being also elastically connected to the front wheel stopper 5, and a proximity switch 3 being fixedly installed to a side of the vehicle loading plate 4 close to the L-shaped pressure plate 1.
[0023] Reference Figure 1 and Figure 2 The right end of the loading plate 4 is the entrance and exit end, and the left end is the end end. The car enters the loading plate 4, the wheel 7 passes the front wheel stop 5, and rolls on the L-shaped pressure plate 1. The L-shaped pressure plate 1 rotates downward, and the left end of the L-shaped pressure plate 1 is pressed down and close to the proximity switch 3. The proximity switch 3 sends a signal to the mechanical garage control system, indicating that there is a vehicle on the loading plate 4 and it has been parked in place; when the car drives out of the loading plate 4, the L-shaped pressure plate 1 rebounds to the upper limit position of the lower edge of the rear wheel stop rod 6 under the action of the elastic rebound force, and the proximity switch 3 is reset, indicating that there is no car on the loading plate 4.
[0024] A plurality of spring hinges 2 are fixedly installed between the L-shaped pressure plate 1 and the front wheel stop 5 .
[0025] Reference Figure 1 and Figure 2 The right end of the L-shaped pressure plate 1 is fixed to the left side of the front wheel stop 5 by a spring hinge 2, and when the L-shaped pressure plate 1 is not rolled by the wheel 7, the spring hinge 2 causes the L-shaped pressure plate 1 to tilt (refer to Figure 1 ).
[0026] The rear wheel stopper rod 6 is fixed to the upper edge of the vehicle loading plate 4, and the front wheel stopper 5 is a V-shaped steel.
[0027] Reference Figure 1 The rear wheel stopper 6 is fixed to the upper edge of the vehicle loading plate 4. First, it prevents the wheel 7 from rolling over the rear wheel stopper 6 and then rolling over the proximity switch 3. Second, the L-shaped pressure plate 1 rebounds to the upper limit position of the lower edge of the rear wheel stopper 6 under the action of the elastic rebound force to limit the position. The V-shaped structure of the front wheel stopper 5 is conducive to the passing of the wheel 7.
[0028] The proximity switch 3 is electrically connected to an audible and visual alarm 8 placed at the entrance and exit of the vehicle loading plate 4 .
[0029] Reference Figure 1 When the left end of the L-shaped pressing plate 1 is pressed down and close to the proximity switch 3, the proximity switch 3 sends a signal to the mechanical garage control system, so that the sound and light alarm 8 is powered on, prompting the driver that the vehicle has stopped in place.
[0030] Working principle: when there is no vehicle on the vehicle loading plate 4, the elastic rebound of the spring hinge 2 causes the L-shaped pressure plate 1 to rebound to the upper limit position of the lower edge of the rear wheel stop bar 6, and the vehicle enters through the right entrance and exit side of the vehicle loading plate 4, and when the wheel 7 passes the front wheel stop 5, it rolls on the L-shaped pressure plate 1, and the L-shaped pressure plate 1 rotates downward, and the left end of the L-shaped pressure plate 1 is pressed down and close to the proximity switch 3. The proximity switch 3 sends a signal to the mechanical garage control system, so that the sound and light alarm 8 is energized, prompting the driver that the vehicle has stopped in place. When the car drives out of the vehicle loading plate 4, the L-shaped pressure plate 1 rebounds to the upper limit position of the lower edge of the rear wheel stop bar 6 under the action of the rebound force of the spring in the spring hinge 2, and the proximity switch 3 is reset, indicating that there is no vehicle on the vehicle loading plate 4.
