Description

Technical Field

[0001] This utility model relates to the field of parking lock technology, specifically a flat flip-top parking lock. Background Technology

[0002] Parking locks are devices used to protect parking spaces from occupancy. They are commonly installed in parking lots and residential parking areas. The main body is made of metal or high-strength plastic, and they achieve locking via mechanical or electric means. Traditional manual parking locks require manual operation, while smart locks can automatically open and close via Bluetooth, an app, or a ground loop sensor. After installation, they can lock the parking space to prevent unauthorized occupation. They are suitable for private parking spaces and commercial parking lots. In recent years, with the development of smart parking, smart parking locks with license plate recognition and cloud management functions have gradually become more widespread, improving parking management efficiency and security. However, existing parking locks still have some problems in use:

[0003] For example, the parking lock with application number 201520083885.6 has the following technical solution: It includes a parking lock body, comprising: a baffle motor fixed inside the parking lock body; a baffle transmission gear located inside the parking lock body, having a transmission thread, connected to the baffle motor, the baffle motor driving the baffle transmission gear to rotate; a baffle shaft located inside the parking lock body, having teeth, meshing with the transmission thread, the baffle transmission gear driving the baffle shaft to rotate; a battery fixed inside the parking lock body and connected to the baffle motor; a switch connected to the baffle motor, connecting and disconnecting the baffle motor; and a baffle located outside the parking lock body, fixed to the baffle shaft, the baffle shaft driving the baffle to rotate.

[0004] Existing parking locks suffer from problems such as high false alarm rates, cumbersome installation, and risk of chassis scratches. Traditional single-sensor parking locks are prone to false alarms due to environmental interference, require concrete pouring for installation, which is time-consuming and labor-intensive, and the fixed-angle flip cover is prone to scratching low-chassis vehicles. In addition, most parking locks lack anti-roll-down structural design, making them easily damaged under vehicle pressure, and their battery life is also insufficient to meet the needs of long-term outdoor use.

[0005] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0006] To address the aforementioned issues, an innovative design was developed based on the existing parking lock. Utility Model Content

[0007] The purpose of this utility model is to provide a flat flip-top parking lock to solve the problems of high misjudgment, cumbersome installation, and short battery life mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A flat-panel flip-top parking lock includes a base, a first protective shell mounted on the left side of the base, a second protective shell mounted on the right side of the base, and a flat body disposed on top of the base. A radar geomagnetic detection device and an angle sensor are disposed inside the first protective shell. A control box is disposed on the rear side inside the second protective shell, and a rotating mechanism is disposed on the front side of the control box. A battery box is disposed on the front side of the rotating mechanism. A rotating shaft is connected to the left output end of the rotating mechanism, and the front side of the flat body is sleeved on the outside of the rotating shaft. The flat body is positioned above the base, forming a rotating structure.

[0010] Preferably, mounting plates are fixedly provided on both the left and right sides of the base, and the mounting plates are fixed to the ground by drilling holes in the ground and installing screws.

[0011] Using the above technical solution, the mounting plates on the left and right sides of the base are fixed to the ground with expansion bolts. The pull-out force of a single bolt is >3kN, and the total pull-out force is 12kN, which can withstand a level 12 typhoon. The installation only takes ten minutes, which is more efficient than traditional concrete pouring.

[0012] Preferably, the control box is equipped with a multi-level voice broadcasting system, and the multi-level voice broadcasting system has a built-in digital power amplifier chip to drive a waterproof speaker, and the voice broadcasting volume is ≥90dB.

[0013] Using the above technical solution, the multi-level voice broadcast system in the control box can broadcast the parking space status in real time, such as "The vehicle is about to be hit, and the angle is being adjusted." With the waterproof speaker design, the voice can be clearly heard in adverse environments such as rain, improving the convenience of user operation guidance.

[0014] Preferably, the rotating mechanism is equipped with a stepper motor, and the stepper motor amplifies the torque through a gear set to achieve silent lifting of the flat plate body.

[0015] Using the above technical solution, the stepper motor of the rotating mechanism amplifies the torque by 20 times through the gear set, and the noise level is ≤55dB when driving the flat plate to lift and lower, which is lower than that of traditional parking locks. At the same time, it achieves precise angle control of 0.5° to ensure that the lifting angle of the flat plate matches the height of the vehicle chassis.

[0016] Preferably, the geomagnetic sensor inside the radar geomagnetic detection device monitors magnetic field disturbances in the parking space area, and combines it with a 24GHz millimeter-wave radar to scan the vehicle chassis outline. The dual signals are fused to determine the vehicle's occupancy status. The radar inside the radar geomagnetic detection device measures the vehicle chassis's height from the ground in real time and dynamically adjusts the lifting angle of the flat plate body.

[0017] Using the above technical solution, the radar geomagnetic detection device integrates geomagnetic sensors and 24GHz millimeter-wave radar signals, reducing the false judgment rate by 60% compared to a single sensor. At the same time, the radar measures the chassis height in real time and dynamically adjusts the lifting angle of the flat plate to avoid scratching low-profile vehicles, such as cars with high chassis.

[0018] Preferably, the right side of the angle sensor is connected to the left end of the rotating shaft, and a tension spring is provided at the connection end of the angle sensor. The tension spring is hung on the fixing plate, and the fixing plate is fixedly installed on the upper surface of the mounting plate.

[0019] Using the above technical solution, the angle sensor is connected to the fixed plate through a tension spring, providing real-time feedback on the lifting angle of the plate body with a positioning error of ≤0.3°. When the plate encounters an obstacle, the tension spring can buffer the impact force of 20N to prevent damage to the sensor.

[0020] Preferably, the interior of the flat plate body adopts a honeycomb-shaped skeleton, and a buffer pad is provided at the rear end of the flat plate body.

[0021] Using the above technical solution, the honeycomb aluminum alloy skeleton inside the flat plate body makes its compressive strength ≥2 tons, and the displacement after being crushed by a 5-ton heavy truck is <0.2mm. The rear buffer sleeve is made of EVA material, which can absorb the impact force when the vehicle is parked and avoid structural damage caused by the collision between the flat plate and the base.

[0022] Compared with the prior art, the beneficial effects of this utility model are: this flat-panel flip-top parking space lock,

[0023] 1. Dual-sensor fusion and adaptive anti-scratch design: The radar geomagnetic detection device monitors magnetic field disturbances through geomagnetic sensors and combines them with millimeter-wave radar to scan the chassis outline, so as to accurately determine the vehicle's occupancy status. When the vehicle drives in, the radar measures the chassis height in real time and dynamically adjusts the lifting angle of the flat plate body. For example, when the chassis height is 150mm, it automatically rises to 45°, which reduces the risk of scratches by 80% compared with the traditional fixed angle design.

[0024] 2. High-strength structure and long battery life: The honeycomb frame of the flat panel body, combined with the buffer pad, can withstand 2.5 tons of crushing without deformation. The Dacromet-coated screws of the mounting plate are resistant to salt spray for 1000 hours, adapting to harsh outdoor environments. The lithium iron phosphate battery pack in the battery box supports wide temperature range of -20℃ to 60℃. With the photovoltaic panel, it generates an average of 0.5kWh of electricity per day, and the battery life can reach 30 days on cloudy and rainy days. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5 This utility model provides a technical solution:

[0033] A flat-panel flip-top parking lock includes a base 1, a first protective shell 2 installed on the left side of the base 1, a second protective shell 3 installed on the right side of the base 1, and a flat body 4 disposed on top of the base 1. A radar geomagnetic detection device 11 and an angle sensor 12 are disposed inside the first protective shell 2. A control box 8 is disposed on the rear side inside the second protective shell 3, and a rotating mechanism 9 is disposed on the front side of the control box 8. A battery box 10 is disposed on the front side of the rotating mechanism 9. A rotating shaft 5 is connected to the left output end of the rotating mechanism 9, and the front side of the flat body 4 is sleeved on the outside of the rotating shaft 5. The flat body 4 is located above the base 1 to form a rotating structure.

[0034] Mounting plates 7 are fixedly installed on both the left and right sides of the base 1. The mounting plates 7 are fixed to the ground by drilling holes in the ground and installing screws. The mounting plates 7 on the left and right sides of the base 1 are fixed to the ground by expansion screws. The pull-out force of a single screw is >3kN, and the total pull-out force is 12kN, which can withstand a level 12 typhoon. The installation only takes ten minutes, which is more efficient than traditional concrete pouring.

[0035] The control box 8 is equipped with a multi-level voice broadcast system, which has a built-in digital power amplifier chip to drive a waterproof speaker. The voice broadcast volume is ≥90dB. The multi-level voice broadcast system in the control box 8 can broadcast the parking space status in real time, such as "The vehicle is about to be hit, and the angle is being adjusted". With the waterproof speaker design, the voice can be clearly heard in harsh environments such as rainy days, which improves the convenience of user operation guidance.

[0036] The rotating mechanism 9 is equipped with a stepper motor, and the stepper motor amplifies the torque through a gear set to achieve silent lifting of the flat plate body 4. The stepper motor of the rotating mechanism 9 amplifies the torque by 20 times through the gear set, and the noise level when driving the flat plate body 4 to lift and lower is ≤55dB, which is lower than that of traditional parking locks. At the same time, it achieves precise angle control of 0.5° to ensure that the lifting angle of the flat plate matches the height of the vehicle chassis.

[0037] The radar geomagnetic detection device 11 uses a geomagnetic sensor inside to monitor magnetic field disturbances in the parking space area. Combined with a 24GHz millimeter-wave radar scanning the vehicle chassis outline, the dual signals are fused to determine the vehicle's occupancy status. The radar inside the device 11 measures the vehicle chassis's ground clearance in real time and dynamically adjusts the lifting angle of the flat plate 4. Angle sensor 12 is connected to the left end of the rotating shaft 5 on its right side, and a tension spring 14 is installed at the connection end of angle sensor 12. The tension spring 14 is hung on a fixing plate 13, which is fixedly installed on the upper surface of the mounting plate 7. The magnetic detection device 11 integrates a geomagnetic sensor and a 24GHz millimeter-wave radar signal, reducing the false judgment rate by 60% compared to a single sensor. At the same time, the radar measures the chassis height in real time with an accuracy of ±5mm, dynamically adjusting the lifting angle of the flat plate body 4 from 0° to 70° to avoid scratching low-profile vehicles, such as cars with high chassis. The angle sensor 12 is connected to the fixed plate 13 through a tension spring 14, providing real-time feedback on the lifting angle of the flat plate body 4 with a positioning error of ≤0.3°. When the flat plate encounters an obstacle, the tension spring 14 can buffer a 20N impact force to prevent damage to the sensor.

[0038] The internal structure of the flat plate body 4 is a honeycomb skeleton, and a buffer sleeve 6 is provided at the rear end of the flat plate body 4. The honeycomb aluminum alloy skeleton inside the flat plate body 4 makes its compressive strength ≥2 tons, and the displacement after being crushed by a 5-ton heavy truck is <0.2mm. The buffer sleeve 6 at the rear is made of EVA material, which can absorb the impact force when the vehicle is parked and avoid structural damage caused by the collision between the flat plate body 4 and the base 1.

[0039] Working principle:

[0040] When this utility model is in use, when a vehicle drives into a parking space, the geomagnetic sensor of the radar geomagnetic detection device 11 first detects the change in the magnetic field, triggering the radar to scan the outline of the vehicle chassis. After the control box 8 confirms that the vehicle occupies the space by fusing the data from the two sensors, the radar measures the height of the chassis off the ground in real time and transmits the data to the rotating mechanism 9. The stepper motor drives the rotating shaft 5 through the gear set, which drives the flat plate body 4 to rise. The angle sensor 12 provides real-time feedback of the angle. When it is raised to the appropriate height, such as 60° corresponding to a chassis height of 200mm, it stops, blocking the rear wheels of the vehicle.

[0041] Safety protection and power supply mechanism: If the tablet body 4 encounters an obstacle during the lifting process, the angle sensor 12 detects an angle abnormality, the control box 8 identifies the stall through current monitoring, drives the stepper motor to automatically reverse 0.5° to release stress, and the battery box 10 supplies power to the system. The battery box 10 uses a 24V / 20Ah lithium iron phosphate battery pack that supports a wide temperature range of -20℃ to 60℃. The battery cavity is filled with flame-retardant epoxy resin glue of UL94V-0 grade. The glue is vacuum-filled in three sections to ensure no air bubbles and completely isolate the risk of thermal runaway. The battery compartment adopts a sliding rail design and can be pulled out and replaced within 3 seconds after pressing to unlock. It supports hot-swapping. The surface of the tablet body 4 integrates a monocrystalline silicon photovoltaic panel with an efficiency of ≥22%, combined with a nano self-cleaning film layer to reduce contamination. The average daily power generation is ≥0.5kWh, supporting 30 days of continuous operation in cloudy and rainy weather, and achieving low power consumption operation.
