Description

Technical Field

[0001] The utility model relates to the technical field of vehicle management, in particular to a wheel positioning device for a parking lot. Background Art

[0002] Wheel aligners are also called wheel stoppers, reversing pads, blockers, and car blockers. They have good pressure resistance and can prevent vehicles from going offside when reversing into a garage, avoiding collisions with other vehicles. They are the best facilities to define the correct parking position of vehicles. When reversing into a garage, the correct way is to put the vehicle in neutral gear or drive the vehicle forward a short distance from the aligner after the rear wheels of the vehicle are against the aligner. Since many drivers have bad driving habits, they often press the rear wheels in whole or in part against the wheel aligner, and the edges or corners of the wheel aligner against the tires, which will generate greater pressure on the tires, thereby affecting the life of the tires. In the case of nails or cracks in the tires, it will accelerate the occurrence of tire blowouts, posing a major hidden danger to the safety of people and vehicles. Utility Model Content

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-4As shown, a wheel alignment device for a parking lot includes a base plate 1, a shell 2, a spring 3, an airbag 4 and a sound-generating tube 5. One end of the shell 2 is hinged to one end of the base plate 1, the spring 3 is elastically connected between the shell 2 and the base plate 1, the airbag 4 is installed on the base plate 1, and the sound-generating tube 5 is connected to the airbag 4. When the shell 2 is pressed down, the shell 2 can rotate to squeeze the airbag 4 and compress the spring 3; the airbag 4 and the sound-generating tube 5 are telescopic tubes made of plastic, which are commonly used as built-in accessories of vinyl toys. A sound can be made by squeezing them. They are transplanted into the present device to make sounds and remind the driver of the wheel status.

[0024] In the above embodiment, the cross-sections of the bottom plate 1 and the shell 2 are both fan-shaped, which adapts to the movement trajectory of the shell 2 when rotating. When the shell 2 squeezes the airbag 4, the shell 2 and the bottom plate 1 can be staggered and do not interfere with each other. The bottom plate 1 is provided with a groove 6, and the shell 2 is slidably connected in the groove 6 to provide guidance for the shell 2. At the same time, a cavity with a certain sealing property is formed between the shell 2 and the bottom plate 1, so that when the shell 2 is pressed downward by an external force, the air in the cavity slowly flows out from the gap between the shell 2 and the bottom plate 1, so that the shell 2 can slowly rotate and press downward, which can provide roadblock feedback to the driver in the car and maintain the continuous sounding of the generating tube. The side of the bottom plate 1 is provided with an arc groove 7 connected to the groove 6, and the sound generating tube 5 leads to the groove 6, providing a channel for the gas in the airbag 4 to be discharged and also providing a channel for sound transmission; the side of the shell 2 is provided with a limit block 8, and the limit block 8 slides in the arc groove 7 to prevent the shell 2 and the bottom plate 1 from being separated from each other, and also provide a space for the limit block 8 to move.

[0025] In the above embodiment, the bottom plate 1 is provided with a position sensor 9, and the detection end of the position sensor 9 is located on the side of the arc groove 7. After the wheel abuts against and presses down the shell 2, the position sensor 9 will be triggered, thereby feeding back the parking space status to the parking lot intelligent system; different information can be conveyed according to the different position sensors 9 triggered. The bottom plate 1 is provided with a battery pack 10 and a communication component 11. The battery pack 10, the communication component 11 and the position sensor 9 are electrically connected. The battery pack 10 supplies power to the communication component 11 and the position sensor 9. After the position sensor 9 is triggered, the signal can be wirelessly transmitted through the communication component 11. The corresponding positions of the bottom plate 1 and the shell 2 are provided with a cylinder 12, and the spring 3 is located in the cylinder 12, providing an installation position for the spring 3, while preventing the spring 3 from making a sound and deforming laterally under the clamping of the shell 2 and the bottom plate 1, affecting the normal use of the spring 3. The bottom plate 1 is provided with a mounting hole 13 for mounting and locking the ground. The airbag 4 is provided with a partition 14 on both sides to prevent the airbag 4 from interfering with the spring 3 when being squeezed. The lower end of the housing 2 is provided with a boss 15, which can squeeze the airbag 4. The boss 15 is close to the lower end surface of the housing 2, and there is a gap between the boss 15 and the airbag 4, so that the boss 15 can quickly abut against the airbag 4 when the housing 2 is pressed down. The upper end of the housing 2 is provided with a reflective sticker 16 to provide a warning to the driver.

[0026] Description of the working method of this utility model:

[0027] To install the device in a parking space, you must first drill holes in the ground at the corresponding positions, then fix it with expansion screws and the mounting holes 13 on the bottom plate 1, and then hinge the shell 2. When the vehicle reverses into the parking space, the wheels first abut against the shell 2. As the vehicle continues to reverse, the shell 2 rotates around the hinge and presses down. At this time, the gas in the cavity slowly leaks out from between the shell 2 and the bottom plate 1. Supported by the air pressure, the shell 2 slowly rotates to provide the driver with roadblock feedback, reminding the driver to reverse into place; at the same time, when the shell 2 slowly descends, it will also compress the spring 3 and squeeze the airbag 4. The gas in the airbag 4 will make a sharp sound in the sound tube 5, reminding the driver of the compressed state of the shell 2; when the wheel runs over the shell 2 in whole or in part, the wheel continues to Continue to apply pressure to the shell 2, the sound of the sound tube 5 will continue for a period of time, and the sound will not stop until the shell 2 rotates and drops to the lower limit. The height of the synchronous wheel position will also drop accordingly, approaching or returning to the ground, so that the situation where the wheel is locally subjected to a large pressure is alleviated; after the vehicle moves forward slightly away from the device, the external force on the shell 2 is removed, and the shell 2 tends to return to its original position under the action of the spring 3. At the same time, under the action of the cavity pressure, the gas slowly enters the cavity from the gap between the shell 2 and the bottom plate 1, so that the shell 2 gradually rotates and lifts and finally completes the return.

[0028] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
