[0002] With the explosive growth in the number of motor vehicles, parking difficulties have become one of the most troublesome problems for residents when driving. Multi-level parking garages are mechanical or equipment systems used to store and retrieve vehicles in large quantities. They are an effective tool for parking lot management companies to increase parking capacity, revenue, and parking fee income. Multi-level parking garages are characterized by convenient access, economical operation, easy maintenance, and small footprint, making them a current solution to the problem of a large number of vehicles and limited parking space.

[0003] However, when a vehicle enters the car of a multi-level parking garage, the driver cannot determine whether the vehicle is parked in the correct position inside the car. Furthermore, some drivers may forget to engage the handbrake or leave without putting the car in park after parking, causing the vehicle to roll away from the parking space. Utility Model Content

[0004] The main purpose of this utility model is to provide a vehicle positioning device inside the car to solve the problem in the prior art that drivers cannot determine whether the vehicle is parked in the correct position inside the car, and that some drivers may forget to engage the handbrake or leave without putting the car in parking gear after parking, causing the vehicle to roll away from the parking space.

[0005] To solve the above problems, the present invention adopts the following technical solution: a vehicle positioning device in a car, including a car for parking a vehicle, the front side of the car having an opening for the vehicle to enter, the bottom surface of the car being provided with a sensing component for sensing the position of the wheels and a first stop component for limiting the wheels of the vehicle, an alarm device being provided on the side of the car away from the opening, when the sensing component senses that the wheels have traveled to a preset position, the alarm device emits an audible and visual alarm, and a controller is fixedly installed on one side of the car, the controller being electrically connected to the stop component, the sensing component and the alarm device respectively.

[0006] Furthermore, the first stop assembly includes a first baffle and a second baffle, which are spaced apart along the length of the car. The first baffle and the second baffle are slidably disposed inside the bottom surface of the car. When the vehicle is parked in a designated position, one of the wheels on the side away from the opening direction is located between the first baffle and the second baffle. The bottom surface of the car is fixed with a power unit for driving the first baffle and the second baffle to rise and fall.

[0007] Furthermore, the power unit is a telescopic cylinder, and the output end of the telescopic cylinder is fixedly connected to the bottom surfaces of the first baffle and the second baffle, respectively.

[0008] Furthermore, a second stopping component is provided. The second stopping component has the same structure as the first stopping component and is electrically connected to the controller. When the vehicle stops at a designated position, one of the wheels on the side away from the opening direction is located between the first baffle and the second baffle of the first stopping component, and one of the wheels on the side closer to the opening direction is located between the first baffle and the second baffle of the second stopping component.

[0009] Furthermore, the first stop component and the second stop component are located on both sides of the car width direction, respectively.

[0010] Furthermore, the bottom surface of the car is provided with a first sliding groove and a second sliding groove spaced apart.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 3 As shown, a vehicle positioning device inside a car includes a car 1, a sensing component 2, a first stop component 3, an audible and visual alarm device 5, and a controller 6. The car 1 is a prior art device used for parking vehicles. The front side of the car 1 has an opening 11 for facilitating vehicle entry. The sensing component 2 is disposed on the bottom surface of the car 1 to sense the position of the wheels. The alarm device 5 is a prior art audible and visual alarm device disposed inside the car 1. In this embodiment, the alarm device 5 is fixed on the side of the car 1 away from the opening 11, but this is not a limitation. The alarm device 5 can be disposed at any position inside the car 1, i.e., a position convenient for reminding the driver. When the sensing component 2 senses that the vehicle's wheels have moved to a preset position, the alarm device 5 emits an audible and visual alarm. The first stop component 3 is used to limit the vehicle's wheels. Specifically, when the vehicle is parked in a designated position, the first stop component 3 can limit the vehicle to prevent the vehicle from rolling away from the parking space if the handbrake is not engaged or the parking gear is not engaged. The controller 6 is a PLC controller 6 in the prior art. The controller 6 is electrically connected to the stop component, the sensing component 2 and the alarm device 5 respectively.

[0023] During implementation, the vehicle enters the car 1 from the opening 11 direction of the car 1. When the sensing component 2 senses that the wheels have reached the preset position, it activates the alarm to remind the driver. When the vehicle stops at the designated position, the first stop component 3 is activated to limit the vehicle and prevent it from rolling away.

[0024] In this embodiment, the first stop assembly 3 includes a first baffle 31, a second baffle 32, and two power units 33. The first baffle 31 and the second baffle 32 are spaced apart along the length of the car body 1. The first baffle 31 and the second baffle 32 are slidably disposed inside the bottom surface of the car body 1. When the vehicle is parked in the designated position, one of the wheels on the side away from the opening 11 is located between the first baffle 31 and the second baffle 32. The two power units 33 are fixedly disposed inside the bottom surface of the car body 1 and are used to drive the first baffle 31 and the second baffle 32 to rise and fall respectively. Preferably, the power unit 33 is a telescopic cylinder in the prior art. The output end of the telescopic cylinder is fixedly connected to the bottom surface of the two baffles, thereby driving the first baffle 31 and the second baffle 32 to rise and fall respectively through the two power units 33.

[0025] It should be noted that the first baffle 31 is located on the side of the car 1 away from the opening 11, and the second baffle 32 is located on the side of the car 1 closer to the opening 11. In practice, when the vehicle enters the car 1, the sensing component 2 senses that the wheels have reached a preset position. One of the power units 33 then lifts the first baffle 31 (at this time, the top of the first baffle 31 protrudes from the bottom surface of the car 1) to initially limit the vehicle and prevent collision with the side of the car 1 away from the opening 11. In other words, after the first baffle 31 is lifted, when the wheels touch the first baffle 31, the driver will feel the wheels being obstructed, thus reminding the driver that the vehicle has reached the designated position. When the sensing component 2 senses that the wheels have reached the designated position (between the first baffle 31 and the second baffle 32), another power unit 33 lifts the second baffle 32. Thus, the first baffle 31 and the second baffle 32 can limit the wheels' rolling direction on both sides, preventing the vehicle from rolling away.

[0026] Preferably, a guardrail 7 is fixed to the side wall of the car 1 on the side away from the opening 11. The guardrail 7 is made of flexible plastic. This is to prevent the vehicle from colliding with the side of the car 1 away from the opening 11 due to driver error during the vehicle's entry, and to minimize damage by installing the guardrail 7.

[0027] In this embodiment, the car 1 is further provided with a second stopping component 4. The second stopping component 4 has the same structure as the first stopping component 3. When the vehicle stops at a designated position, one of the wheels on the side away from the opening 11 is located between the first baffle 31 and the second baffle 32 of the first stopping component 3, and one of the wheels on the side closer to the opening 11 is located between the first baffle 31 and the second baffle 32 of the second stopping component 4. Preferably, the first stopping component 3 and the second stopping component 4 are located on both sides of the width direction of the car 1, so as to simultaneously limit one of the front wheels and one of the rear wheels of the vehicle.

[0028] In this embodiment, the bottom surface of the car 1 is provided with a first sliding groove 12 and a second sliding groove 13 spaced apart. The first sliding groove 12 is located on the side of the first baffle 31 near the opening 11, and the second sliding groove 13 is located between the first baffle 31 and the second baffle 32. The sensing component 2 includes two pressure sensors 21 and two sliders 22. The two pressure sensors 21 are respectively fixed on the bottom surface of the first sliding groove 12 and the second sliding groove 13. The bottom ends of the two sliders 22 are respectively located above the two pressure sensors 21 and are slidably connected to the first sliding groove 12 and the second sliding groove 13. The interior of the first sliding groove 12 and the second sliding groove 13 is provided with elastic parts 23 for pushing the corresponding sliders 22 to move away from the pressure sensors 21. Under normal conditions, the top ends of the two sliders 22 protrude from the bottom surface of the car 1 through the corresponding elastic parts 23. Specifically, each slider 22 has an annular plate 221 fixed on its outer edge, and the elastic part 23 is a compression spring. The two ends of the compression spring abut against the bottom surface of the annular plate 221 and the bottom surface of the corresponding first groove 12 or second groove 13, respectively.

[0029] In a specific implementation of this utility model, when the driver drives the vehicle into the car 1 (including driving forward or reversing), when the wheels are above the slider 22 in the direction of the opening 11, the weight of the vehicle will move the slider 22 in the first groove 12 towards the pressure sensor 21, so that the bottom of the slider 22 abuts against the pressure sensor 21. At this time, the alarm device 5 will issue an audible and visual alarm (at this time, a yellow light can be emitted) to remind the driver that the vehicle is about to drive to the designated position. At the same time, the first baffle 31 of the first stop assembly 3 and the second stop assembly 4 will be raised to avoid the driver's operation error, driving past the designated position and colliding with the guardrail 7.

[0030] It should be noted that the first chute 12 is located between the first stop assembly 3 and the second stop assembly 4. This way, when both wheels on the side closest to the guardrail 7 have passed through the first chute 12, the first baffles 31 of the first stop assembly 3 and the second stop assembly 4 will lift up.

[0031] Next, when the vehicle's wheels are between the first baffle 31 and the second baffle 32, the vehicle's weight moves the slider 22 in the second slide groove 13 towards the pressure sensor 21, causing the bottom of the slider 22 to contact the pressure sensor 21. This triggers an audible and visual alarm (a red light may be emitted at this time) to alert the driver that the vehicle has reached the designated position. Simultaneously, the second baffle 32 of the first stop assembly 3 and the second stop assembly 4 lifts, limiting one of the front wheels and one of the rear wheels of the vehicle to prevent it from rolling away. When the driver needs to drive the vehicle out, they can reset the first stop assembly 3 and the second stop assembly 4 via the human-machine interface of the controller 6, allowing the vehicle to be driven out.

[0032] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
