Description

Technical Field

[0001] This utility model relates to the field of vehicle limiters, and in particular to a vehicle limiter for use in smart parking lots. Background Technology

[0002] With the advancement of smart parking system construction, efficient and safe parking experiences have become core requirements. Currently, traditional parking spaces often lack precise guidance devices, leading to driver misalignment and increased risk of collisions, especially at night when visibility is poor. Existing parking limit devices are mostly simple in structure, only providing physical obstruction and lacking real-time feedback, making it difficult for drivers to judge parking opportunities in time, thus affecting parking efficiency. Therefore, there is an urgent need for an intelligent parking limit device that integrates sensing, warning, and auxiliary guidance functions to improve parking accuracy and safety, and meet the automation and user-friendliness requirements of smart parking systems.

[0003] Existing technology patent announcement number CN221073693U discloses a vehicle limiter for smart parking lots, relating to the field of smart parking technology. It includes a base plate, with an alarm mechanism and a protective mechanism respectively installed on top of the base plate. The alarm mechanism includes two support columns, the bottom surface of which is fixedly connected to the upper surface of the base plate. A connecting frame is fixedly connected to the back of the two support columns. Three buffer springs are fixedly connected to the inner wall of the connecting frame. A rubber plate is fixedly connected to the end of the three buffer springs away from the connecting frame. Four pressure sensors are fixedly connected to the front of the rubber plate. Alarm lights are fixedly connected to the sides of the two support columns that are away from each other. It can promptly remind the driver to stop the vehicle, increasing the functionality of the vehicle limiter, improving its safety, preventing damage from collisions when parking, and extending the service life of the smart parking lot vehicle limiter.

[0004] Existing technology reduces the risk of collision damage to vehicle limiters by using three buffer springs, four pressure sensors, a rubber plate, and warning lights. However, in actual use, this vehicle limiter has a relatively complex structure, is difficult to install, and its components, such as the buffer springs, are exposed to the elements, making them susceptible to aging and failure due to environmental factors, increasing maintenance costs. Furthermore, this vehicle limiter lacks nighttime reflective recognition measures, making it difficult for drivers to accurately identify parking spaces in low-light conditions, increasing the risk of collision. Therefore, we propose a vehicle limiter for smart parking lots that solves the problems of complex structure, inconvenient installation, high maintenance costs, and lack of nighttime parking assistance measures. This new technology improves parking convenience while ensuring parking safety, and also reduces the manufacturing and maintenance costs of the parking limiter. Utility Model Content

[0005] The purpose of the present utility model is to provide a vehicle limiter for a smart parking lot, which solves the problems of the complex structure and inconvenient installation of the existing parking limiters, the high later maintenance cost, and the lack of night auxiliary parking measures mentioned in the above background technology.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A vehicle limiter for a smart parking lot includes a parking space body. A limit baffle is fixedly installed on the outside of the parking space body. A first fixing block is fixedly welded to the left front end of the limit baffle. A first upright post is fixedly installed on the top of the first fixing block. A warning light is fixedly installed on the top of the first upright post. A second fixing block is fixedly welded to the left rear end of the limit baffle. A second upright post is fixedly installed on the top of the second fixing block. An infrared occlusion sensor is fixedly installed on the side of the second upright post close to the parking space body. The infrared occlusion sensor realizes the transmission and control of electrical signals through a relay. After the infrared occlusion sensor detects occlusion, it outputs an electrical signal to trigger the relay to control the warning light to light up.

[0007] Among them, a first reflective strip is fixedly pasted on the inner wall of the rear end of the limit baffle, and a second reflective strip is fixedly pasted on the front surface of the limit baffle.

[0008] Among them, a front-wheel deceleration strip, a rear-wheel deceleration strip and a rear-wheel limit strip are fixedly installed on the top surface of the parking space body. The rear-wheel limit strip is located on the top surface of the parking space body at one end close to the infrared occlusion sensor. The cross-section of the rear-wheel limit strip is a trapezoidal structure. The rear-wheel deceleration strip is located on the side of the rear-wheel limit strip close to the warning light. The rear-wheel limit strip and the rear-wheel deceleration strip are spaced 40 - 60 centimeters apart.

[0009] Among them, a guiding cushion block is fixedly installed at the front end of the parking space body. A number of anti-slip grooves are formed on the surface of the guiding cushion block. The front-wheel deceleration strip is located on the top surface of the parking space body at one end close to the guiding cushion block.

[0010] Among them, a limit rib tube is fixedly welded to the inner wall of the rear end of the limit baffle. The limit rib tube is located 5 - 10 centimeters behind and above the rear-wheel limit strip.

[0011] Among them, reserved installation holes are formed on both sides of the limit baffle. Fixing bolts are provided for the reserved installation holes. The limit baffle is fixedly connected to the parking space body through the fixing bolts.

[0012] The vehicle limiter for a smart parking lot of the present utility model can accurately guide the driver to control the parking timing through the hierarchical reminder of the front-wheel deceleration strip and the rear-wheel deceleration strip, combined with the linkage feedback of the infrared occlusion sensor and the warning light, greatly reducing the position deviation and the risk of vehicle scratching. By enhancing the recognition of the night parking space contour with the first reflective strip and the second reflective strip, and配合 the double limit of the limit rib tube, it provides multiple safety guarantees for night parking.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a vehicle limiter for a smart parking lot, including a parking space body 1, a limit baffle 2 fixedly installed on the outside of the parking space body 1, a first fixing block 3 fixedly welded to the left front end of the limit baffle 2, a first column 4 fixedly installed at the top of the first fixing block 3, a warning light 5 fixedly installed at the top of the first column 4, a second fixing block 6 fixedly welded to the left rear end of the limit baffle 2, a second column 7 fixedly installed at the top of the second fixing block 6, and an infrared obstruction sensor 8 fixedly installed on the upper end of the second column 7 near the side of the parking space body 1. The infrared obstruction sensor 8 realizes the transmission and control of electrical signals through a relay 14. After detecting obstruction, the infrared obstruction sensor 8 outputs an electrical signal to trigger the relay 14 to control the warning light 5 to light up.

[0021] As the vehicle enters the parking space body 1 and gradually approaches the rear of the limit barrier 2, the infrared obstruction sensor 8 on the second pillar 7 detects the vehicle obstruction and outputs an electrical signal to trigger the relay 14. The relay 14 then controls the warning light 5 at the top of the first pillar 4 to illuminate, indicating to the driver that the vehicle has reached a suitable parking position, avoiding collisions or improper parking, realizing intelligent limit reminders, and improving parking standardization and safety.

[0022] A first reflective strip 9 is fixedly affixed to the inner wall of the rear end of the limit baffle 2, and a second reflective strip 10 is fixedly affixed to the front surface of the limit baffle 2. A front wheel speed bump 11, a rear wheel speed bump 12, and a rear wheel limiting strip 13 are fixedly installed on the top surface of the parking space body 1. The rear wheel limiting strip 13 is located on the top surface of the parking space body 1 near the infrared obstruction sensor 8, and has a trapezoidal cross-section. The rear wheel speed bump 12 is located on the side of the rear wheel limiting strip 13 near the warning light 5, with a distance of 40-60 cm between the rear wheel limiting strip 13 and the rear wheel speed bump 12. A guide pad 15 is fixedly installed at the front end of the parking space body 1. Several anti-slip grooves 16 are opened on the surface of the guide pad 15. The front wheel speed bump 11 is located on the top surface of the parking space body 1 near the guide pad 15. The inner wall of the rear end of the limiting baffle 2 is fixedly welded with a limiting rib tube 17. The limiting rib tube 17 is located 5 to 10 centimeters behind the rear wheel limiting band 13. The limiting baffle 2 has reserved installation holes 18 on both sides. The reserved installation holes 18 are equipped with fixing bolts 19. The limiting baffle 2 is fixedly connected to the parking space body 1 through the fixing bolts 19.

[0023] The vehicle enters the parking space via guide blocks 15, with the rear wheels first slowing down over the front wheel speed bump 11. Continuing to enter, the rear wheels further slow down over the rear wheel speed bump 12. Upon reaching the rear wheel limit strip 13, the vehicle body obstructs the infrared obstruction sensor 8, triggering the relay 14 to illuminate the warning light 5, indicating that the vehicle has reached its designated position. The limit baffle 2 and limit rib 17 provide physical restraint, while the first reflective strips 9 and 10 enhance nighttime parking space recognition. The entire system, through the coordinated use of mechanical buffering, sensor-based warnings, and physical restraints, achieves safe and standardized parking.

[0024] Working principle: When parking, the rear wheels of the vehicle first pass through the guide pad 15 onto the parking space body 1, then pass over the front wheel speed bump 11, and then over the rear wheel speed bump 12. The front wheel speed bump 11 and the rear wheel speed bump 12 are both relatively low, primarily serving to remind the driver of the vehicle's current position. After the rear wheels pass over the rear wheel speed bump 12, the driver can apply the brakes to slow down and then slowly approach the rear of the limiting baffle 2. As the rear of the vehicle approaches the rear wheel limiting baffle 13, the infrared obstruction sensor 8 is blocked, which in turn triggers the warning light 5 to illuminate via the relay 14. The warning light 5 is located on the left front of the driver's cab, making it easy for the driver to see and respond promptly to parking maneuvers. A first reflective strip 9 and a second reflective strip 10 are fixedly attached to the inner walls of the front and rear ends of the limiting baffle 2, respectively, so that the driver can see the outline of the parking space in the rearview mirror when reversing at night, reducing the risk of vehicle collision and improving parking safety.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
