Description

Technical Field

[0001] The utility model relates to the technical field of limiters, in particular to a parking lot limiter. Background Technique

[0002] As is well known, a parking lot limiter is a device for restricting the position of parked vehicles. By setting a limiter on one side of a parking space, when a vehicle drives to the limiter, the limiter will stop the vehicle, thus achieving the effect of restricting the parking position of the vehicle. By setting limiters in the parking lot, it can effectively avoid phenomena such as misalignment and overlap when vehicles are parked, ensure the orderliness of vehicle parking, and improve the utilization efficiency of parking spaces.

[0003] In real life, when some drivers park their cars, they generally hit the side wall of the limiter with the wheels to judge whether the vehicle is parked in place, and then turn off the vehicle. At this time, the wheels and the limiter are in a squeezed state. And some limiters are made of rubber materials. When the rubber limiter is squeezed by the wheels for a long time, it shrinks by itself and is always in a tense state, and will deform and harden, reducing its elasticity and service life. And this device does not have a device to adjust the position of the limiter itself, so its practicability is not very good and there is still room for improvement. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a parking lot limiter, which has the characteristics of improving practicability.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A parking lot limiter, including a parking lot, several chutes are arranged on the upper part of the parking lot, and sliders are all slidably connected thereto. Hydraulic cylinders are installed on the right parts of several sliders and are all connected to one end of the corresponding chutes. A limiter is arranged on the upper parts of several sliders. Several dampers are arranged on the left part of the limiter. A protective plate is arranged on the left parts of several dampers. A first switch is installed in the middle of the protective plate. A groove is arranged on the right part of the limiter, and a first time relay is arranged. The first time relay is electrically connected to the hydraulic cylinder through a wire and the first switch. A second switch is installed in the middle of the limiter. A second time relay is arranged in the groove and is electrically connected to the hydraulic cylinder through a wire and the second switch.

[0008] Further, a battery is arranged in the middle of the groove and is electrically connected to the wire, the first switch, the second switch, the first time relay, the second time relay and the hydraulic cylinder.

[0009] Further, a shielding cover is hinged to the right part of the groove, and there is a gap between the shielding cover, the battery, the first time relay and the second time relay.

[0010] Further, a trigger block is arranged in the middle of the protection plate, and the trigger block is made of an elastic material.

[0011] Preferably, there is a gap between the lower part of the protection plate and the upper part of the parking lot, and the protection plate is made of a metal material.

[0012] Preferably, the left end face of the protection plate is arranged in an arc shape.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a parking limiter, which has the following beneficial effects:

[0015] When the wheel presses on the pressing plate and drives the pressing plate to move, the shock absorber contracts to buffer part of the impact force received by the limiter. Then, through the triggering of the second switch, the second time relay is powered, and finally the hydraulic cylinder contracts, driving the limiter and the pressing plate to move to the right, stretching the shock absorber, and finally returning to the original state. At this time, one end of the protection plate leaves the vehicle, and the protection plate no longer receives the extrusion force of the wheel. Therefore, the limiter will not be squeezed by the extrusion force and be in a contracted state, which reduces the deformation and hardening of the limiter to a certain extent, thereby improving the practicality to a certain extent.

Specific implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3, a parking limiter of the present utility model includes a parking lot 1. Several chutes 2 are provided on the upper part of the parking lot 1, and sliders 3 are all slidably connected thereto. Hydraulic cylinders 4 are installed on the right parts of several sliders 3 and are all connected to one end of the corresponding chute 2. When the hydraulic cylinder 4 is started and contracts, it drives the slider 3 to slide in the chute 2, thereby adjusting the position of the slider 3. A limiter 5 is provided on the upper parts of several sliders 3. When the slider 3 slides in the chute 2, it drives the limiter 5 to move on the parking lot 1. Several dampers 6 are provided on the left part of the limiter 5, and a protection plate 7 is provided on the left parts of several dampers 6. The rear wheel of the vehicle presses on the protection plate 7, generating a squeezing force on the protection plate 7, thereby compressing the damper 6 to contract and buffering the impact force, providing a reaction force to the wheel, so that the driver can sense the touch of the rear wheel and then stop the vehicle. The left end face of the protection plate 7 is arranged in an arc shape, which is convenient for full contact with the arc end face of the wheel. A first switch 8 is installed in the middle of the protection plate 7. After one end of the wheel touches the protection plate 7, it presses the first switch 8, making the first switch 8 in an off state. A groove 9 is provided on the right part of the limiter 5, and a first time relay 10 is provided. The first time relay 10 is electrically connected to the hydraulic cylinder 4 through wires and the first switch 8. When the vehicle drives away from the parking lot 1 and the wheel leaves the protection plate 7, the first switch 8 is no longer subjected to the squeezing force and automatically pops up to be in a power-on state, and then powers the first time relay 10. When the time set by the first time relay 10 is reached, the hydraulic cylinder 4 is powered on, and the hydraulic cylinder 4 extends, driving the slider 3, the limiter 5, and the protection plate 7 to move to the left until the hydraulic cylinder 4 extends to the maximum state and reaches the time set by the first time relay 10, and then the power supply to the hydraulic cylinder 4 is cut off, and the hydraulic cylinder 4 stops working. A second switch 11 is installed in the middle of the limiter 5. A second time relay 12 is provided in the groove 9 and is electrically connected to the hydraulic cylinder 4 through wires and the second switch 11. A trigger block 15 is provided in the middle of the protection plate 7. When the vehicle touches the protection plate 7, it drives the protection plate 7 and the trigger block 15 to move. When the damper 6 contracts to the final position, the trigger block 15 touches the second switch 11, and the second switch 11 is in a power-on state, powering the second time relay 12. When the time set by the second time relay 12 is reached, the hydraulic cylinder 4 is powered on, and the hydraulic cylinder 4 contracts, driving the slider 3, the limiter 5, and the protection plate 7 to move to the right until the hydraulic cylinder 4 contracts to the minimum state and reaches the time set by the second time relay 12, and then the power supply to the hydraulic cylinder 4 is cut off, and the hydraulic cylinder 4 stops working. Before the second time relay 12 starts to power the hydraulic cylinder 4, the vehicle is in a parked state. The trigger block 15 is made of an elastic material to reduce the impact force generated by the trigger block 15 on the second switch 11. A battery 13 is provided in the middle of the groove 9 and is electrically connected to the first switch 8, the second switch 11, the first time relay 10, the second time relay 12, and the hydraulic cylinder 4 through wires. The battery 13 provides power,On the right side of the groove 9, a shielding cover 14 is hinged. The shielding cover 14 shields the first time relay 10, the second time relay 12 and the battery 13. There is a gap between the shielding cover 14 and the battery 13, the first time relay 10 and the second time relay 12, which is convenient for the installation of the battery 13, the first time relay 10 and the second time relay 12. There is a gap between the lower part of the protection plate 7 and the upper part of the parking lot 1 to prevent friction between the protection plate 7 and the parking lot 1 when the protection plate 7 moves. The protection plate 7 is made of metal material, and the quality of the metal material is good.

[0022] In summary, when the parking lot limiter is in use, when a vehicle enters the parking space, the wheel touches the protection plate 7, driving the protection plate 7 to move to the right, compressing the shock absorber 6 to contract, buffering the impact force. When it contracts to the final state, it stops contracting. At the same time, the trigger block 15 moving with the protection plate 7 touches the second switch 11. The second switch 11 is in the power-on state, supplying power to the second time relay 12 to start timing. At this time, the driver can park the vehicle. When the time set by the second time relay 12 is reached, power is supplied to the hydraulic cylinder 4. The hydraulic cylinder 4 contracts, driving the slider 3, the limiter 5 and the protection plate 7 to move to the right until the hydraulic cylinder 4 contracts to the minimum state, reaching the time set by the second time relay 12, and power supply to the hydraulic cylinder 4 stops, and the hydraulic cylinder 4 stops working. When the driver drives the vehicle out of the parking space, the first switch 8 automatically pops up and is in the power-on state, then power is supplied to the first time relay 10. When the time set by the first time relay 10 is reached, power is supplied to the hydraulic cylinder 4. The hydraulic cylinder 4 extends, driving the slider 3, the limiter 5 and the protection plate 7 to move to the left until the hydraulic cylinder 4 extends to the maximum state, reaching the time set by the first time relay 10, and power supply to the hydraulic cylinder 4 stops, and the hydraulic cylinder 4 stops working. This process repeats to carry out the parking work.
