Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setup" and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] A ground lock device with fire detection function according to an embodiment of the present invention includes: a housing assembly 100 disposed below the ground; a lock body assembly 200, one side of which is rotatably connected to the housing assembly 100; a drive assembly 300, rotatably connected to the other side of both the housing assembly 100 and the lock body assembly 200, to drive the lock body assembly 200 to switch between an inclined state and a horizontal state; a camera assembly 400, used to acquire license plate information, vehicle status, and battery status, and connected to the upper surface of the lock body assembly 200; a fire extinguishing assembly 500, used to extinguish battery fires, and connected to the upper surface of the lock body assembly 200; and a controller 600, electrically connected to the drive assembly 300, the camera assembly 400, and the fire extinguishing assembly 500, and connected to the housing assembly 100.

[0032] For example, such as Figure 1 As shown, the housing assembly 100 is located below the ground and together with the lock body assembly 200, forms a sunken ground lock structure, which can be completely hidden below the ground when descending to prevent vehicles from being scratched.

[0033] When there is no vehicle in the charging parking space, the camera component 400 is generally aimed at the entrance of the parking space to capture the license plate image of the vehicle. The license plate image is transmitted to the controller 600, which can identify the license plate image. If the identified license plate number is an authorized license plate number, the controller 600 sends a descent signal to the drive component 300 to cause the drive component 300 to retract, thereby driving the other side of the lock body component 200 to descend. During the descent, one side of the lock body component 200 rotates with the housing component 100, the other side of the lock body component 200 rotates with the drive component 300, and the drive component 300 rotates with the housing component 100. This causes the lock body component 200 to change from an inclined state to a horizontal state, thus completing the descent movement of the lock body component 200, allowing the vehicle to smoothly drive into the charging parking space.

[0034] After a vehicle parks in the charging bay, the camera component 400 rotates its camera direction from the bay entrance to the battery area under the vehicle chassis to monitor the battery status. The monitoring process is as follows: The camera component 400 transmits the captured image of the battery area to the controller 600. The controller 600, combined with a background fire image recognition algorithm, identifies the battery area image. If an anomaly is detected in the battery area image, it is determined that the battery is on fire. At this time, the controller 600 sends a fire extinguishing signal to the fire extinguishing component 500, causing the fire extinguishing component 500 to target the battery area for close-range localized fire extinguishing, thereby greatly improving fire extinguishing efficiency. It is evident that, with the combined action of the camera component 400, controller 600, and fire extinguishing component 500, fires can be detected promptly, and effective fire extinguishing measures can be automatically implemented, thereby reducing the extent of vehicle damage and preventing large-scale fires. Furthermore, after the fire extinguishing component 500 extinguishes the fire, the controller 600 can send a message to the management personnel to notify them to replace or replenish the fire extinguishing materials in a timely manner. In addition, the controller 600 can also record the fire extinguishing process and upload it to the cloud platform to facilitate the management personnel to perform subsequent data analysis and troubleshooting.

[0035] The camera component 400 can also be used to acquire vehicle status. When a vehicle is parked in a charging space, the camera component 400 is aimed at the battery area of ​​the vehicle chassis. The controller 600 can also identify the vehicle status based on the battery area image. That is, if the controller 600 can identify whether a vehicle is parked in the charging space based on the battery area image, and if the vehicle has left the charging space, the controller 600 sends a rising signal to the lock body component 200 to cause the drive component 300 to extend, thereby driving the other side of the lock body component 200 to rise. During the rising process, one side of the lock body component 200 rotates with the housing component 100, the other side of the lock body component 200 rotates with the drive component 300, and the drive component 300 rotates with the housing component 100, thereby causing the lock body component 200 to change from a horizontal state to an inclined state to complete the rising movement of the lock body component 200, thus forming a physical barrier in the charging space and preventing other unauthorized vehicles from entering.

[0036] Therefore, with the help of the camera assembly 400, lock body assembly 200, drive assembly 300 and controller 600, the lock body assembly 200 can be automatically raised and lowered, thus facilitating the parking of authorized vehicles; with the help of the camera assembly 400, fire extinguishing assembly 500 and controller 600, the battery status can be monitored, thus automatically extinguishing the fire when the battery catches fire, effectively reducing the property loss of the vehicle owner.

[0037] In some specific embodiments of this utility model, the lock body assembly 200 includes an upper baffle 210 and a side baffle 220. A connecting arm 221 is provided on the side baffle 220. One side of the upper baffle 210 is rotatably connected to the box assembly 100, and the other side of the upper baffle 210 is connected to the side baffle 220. The upper surface of the upper baffle 210 is respectively connected to the camera assembly 400 and the fire extinguishing assembly 500. The connecting arm 221 is rotatably connected to the drive assembly 300.

[0038] For example, such as Figure 1 , Figure 4 and Figure 5 As shown, when the lock body assembly 200 is in a horizontal state, the upper baffle 210 is located on the upper surface of the housing assembly 100, and the side baffle 220 is located inside the housing assembly 100. At the same time, the upper baffle 210 is flush with the ground, which facilitates the parking of vehicles and prevents scratches and other situations.

[0039] When the lock body assembly 200 needs to change from a horizontal state to an inclined state, the drive assembly 300 extends. During the extension process, the drive assembly 300 rotates relative to the housing assembly 100 and the connecting arm 221, allowing the connecting arm 221 to rise smoothly. The connecting arm 221 can drive the side baffle 220 to rise, thereby driving one side of the upper baffle 210 to rotate relative to the housing assembly 100, thus causing the upper baffle 210 to change to an inclined state to prevent other unauthorized vehicles from entering the charging space.

[0040] It can be seen that the upper baffle 210 can smoothly change from a horizontal state to an inclined state only under the combined action of the driving component 300, the rotational relationship between the driving component 300 and the housing component 100 and the connecting arm 221, and the rotational relationship between the upper baffle 210 and the housing component 100. It can be seen that the connection relationship between the components is relatively simple, thereby greatly improving the driving efficiency of the upper baffle 210.

[0041] In some specific embodiments of this utility model, the upper baffle 210 is provided with a through hole, and the fire extinguishing component 500 is connected to the upper baffle 210 through the through hole.

[0042] Specifically, the through hole is generally located below the battery area of ​​the vehicle chassis. Therefore, by fixing the spray position of the fire extinguishing component 500 through the through hole, precise fire extinguishing of the battery can be achieved, greatly improving the fire extinguishing speed.

[0043] In some specific embodiments of this utility model, the fire extinguishing assembly 500 includes a fire extinguisher 510, a switching valve 520, a hose 530, and a nozzle 540. The switching valve 520 is connected to the fire extinguisher 510 and the hose 530 respectively. The switching valve 520 is electrically connected to the controller 600. The hose 530 is detachably connected to the nozzle 540. The fire extinguisher 510 is located inside the housing assembly 100. The nozzle 540 is connected to the upper baffle 210 through a through hole.

[0044] For example, such as Figure 1 and Figure 6 As shown, the fire extinguisher 510 and the housing assembly 100 can be connected in a detachable manner, and the housing assembly 100 can be provided with an inspection window on the side or a pull-out slide groove on the housing assembly 100, so as to facilitate the replacement or maintenance of the fire extinguisher 510.

[0045] When the battery catches fire, the controller 600 sends a fire extinguishing signal to the switching valve 520, causing the switching valve 520 to change from the closed state to the open state. This drives the extinguishing material in the fire extinguisher 510 to pass through the switching valve 520 and the hose 530 in sequence, and spray it from the nozzle 540 towards the battery area, thereby achieving automatic fire extinguishing. The extinguishing material in the fire extinguisher 510 can be set as dry powder or gaseous extinguishing agent.

[0046] Multiple nozzles 540 can be configured, with all nozzles 540 spraying towards the battery area, which helps to improve the extinguishing speed. The nozzles 540 can be conical in shape, with a micro-pore array at their ends, facilitating the directional atomization of the extinguishing material. Furthermore, the nozzles 540 and the hose 530 can be connected by threads, achieving a detachable, sealed connection for easy maintenance, replacement, or cleaning. The hose 530 can be made of a highly flexible, flame-retardant material with excellent high-temperature resistance and corrosion resistance, significantly extending its service life.

[0047] In some specific embodiments of this utility model, the switching valve 520 includes a solenoid valve or a pneumatic valve.

[0048] Specifically, the working principle of a solenoid valve is as follows: an electromagnetic coil is energized to generate a magnetic field, which magnetizes the iron core and attracts the armature, causing the valve core to move and change the state of the fluid channel; the working principle of a pneumatic valve is as follows: compressed air is used as a power source to drive the piston in the cylinder to move, which indirectly drives the valve core to move through the connecting rod.

[0049] It is evident that the working principle of solenoid valves and pneumatic valves is simple and their driving efficiency is high, thereby improving the fire extinguishing efficiency of fire extinguisher 510.

[0050] In some specific embodiments of this utility model, the housing assembly 100 includes an upper frame 110 and a lower housing 120 that are interconnected. The upper frame 110 and the lower housing 120 are connected. The upper frame 110 is rotatably connected to the drive assembly 300 and the upper baffle 210, respectively. The side baffle 220 is disposed inside the upper frame 110, and the fire extinguisher 510 and the controller 600 are disposed inside the lower housing 120.

[0051] For example, such as Figure 3 As shown, the upper frame 110 facilitates the storage of the upper baffle 210 and the side baffle 220, allowing the vehicle to smoothly drive into the charging parking space; the lower box 120 is used to store the fire extinguisher 510 and the controller 600, which helps to separate them from other components, thus providing a relatively safe storage space for the fire extinguisher 510 and the controller 600, making each component independent and not interfering with each other, and improving the working efficiency of each component.

[0052] Since the upper frame 110 and the lower housing 120 are interconnected, the hose 530 can enter the upper frame 110 from the lower housing 120, thus facilitating the connection between the hose 530 and the switch valve 520 and the nozzle 540.

[0053] In some specific embodiments of this utility model, the drive assembly 300 includes a fixing member 310, an electric push rod 320 and a rotating member 330. The fixing member 310 is connected to the housing assembly 100, the electric push rod 320 is rotatably connected to the fixing member 310, the electric push rod 320 is connected to the rotating member 330, and the rotating member 330 is rotatably connected to the connecting arm 221.

[0054] For example, such as Figure 2 As shown, the fixing member 310 can fix the electric push rod 320 on the housing assembly 100. The electric push rod 320 can drive the rotating member 330 to rise and fall. The rotating member 330 can drive the side baffle 220 to rise and fall, thereby driving the upper baffle 210 to switch between a horizontal state and an inclined state.

[0055] It is evident that the change in the state of the upper baffle 210 is achieved through the combined action of the extension and retraction of the electric push rod 320, the rotational relationship between the rotating component 330 and the connecting arm 221, the rotational relationship between the fixed component 310 and the electric push rod 320, and the rotational relationship between the upper baffle 210 and the housing assembly 100. This demonstrates that the connection between the components is relatively simple, thereby greatly improving the driving efficiency of the upper baffle 210.

[0056] In some specific embodiments of this utility model, the camera assembly 400 includes a directional camera 410 and a searchlight 420. The directional camera 410 is connected to the upper surface of the lock body assembly 200, and the searchlight 420 is fastened to the upper surface of the lock body assembly 200. The controller 600 is electrically connected to the directional camera 410 and the searchlight 420 respectively.

[0057] For example, such as Figure 1 As shown, the directional camera 410 has a multi-angle rotation function, which makes it easier for the directional camera 410 to obtain license plate information, vehicle status and battery status.

[0058] Since the environment of underground parking garages and the undercarriage of vehicles is generally dark, to prevent image distortion, blurring, or feature loss during photography by the turnaround camera 410 in dim lighting conditions, which could lead to low recognition rates and delays in authorized vehicle and fire detection by the controller 600, a spotlight 420 is installed. This provides a bright illumination environment for the turnaround camera 410, improving the clarity of the images captured by the camera and thus enhancing the efficiency of license plate recognition, battery status recognition, and vehicle status recognition. Therefore, the combined effect of the turnaround camera 410 and the spotlight 420 significantly improves the accuracy of authorized vehicle and fire detection. The spotlight 420 is fixed to the upper surface of the lock body assembly 200 using a snap-fit ​​method, facilitating its installation and maintenance.

[0059] In some specific embodiments of this utility model, a buzzer 700 for alarm is also included. The buzzer 700 is connected to the upper surface of the lock body assembly 200 and is electrically connected to the controller 600.

[0060] For example, such as Figure 1 As shown, the controller 600 can control the buzzer 700 to emit warning sounds in the following scenarios: before the fire extinguishing component 500 is activated, the buzzer 700 emits a warning sound to prompt personnel to stay away; when the battery is on fire, the buzzer 700 emits a high-frequency alarm sound to inform the outside world of a fire; when an unauthorized vehicle approaches or attempts to occupy a charging parking space, the buzzer 700 emits a warning sound; during the lifting and lowering of the lock body component 200, the buzzer 700 emits a prompt sound to alert surrounding personnel and enhance operational safety.

[0061] In some specific embodiments of this utility model, a charging pile 800 for power supply is also included, which is connected to the lock body assembly 200, the camera assembly 400, the fire extinguishing assembly 500 and the controller 600 respectively.

[0062] For example, such as Figure 7 As shown, the charging pile 800 can charge the lock body assembly 200, the camera assembly 400, the fire extinguishing assembly 500 and the controller 600, so that the above components can operate normally, so as to realize the automatic lifting and lowering of the lock body assembly 200 and the real-time monitoring of the battery.

[0063] Other components and operations of a ground lock device with fire detection function according to an embodiment of the present utility model are known to those skilled in the art and will not be described in detail here.

[0064] The present invention provides a detailed description of a floor lock device with fire detection function according to a specific embodiment. It is worth understanding that the following description is merely illustrative and not a specific limitation of the present invention.

[0065] like Figures 1-7 As shown, a ground lock device with fire detection function includes: an upper frame 110, a lower housing 120, an upper baffle 210, a side baffle 220, a fixing component 310, an electric push rod 320, a rotating component 330, a directional camera 410, a searchlight 420, a fire extinguisher 510, a switch valve 520, a hose 530, a nozzle 540, a controller 600, a buzzer 700, and a charging pile 800; the housing assembly 100 is located below the ground, the side baffle 220 is provided with a connecting arm 221, the upper baffle 210 is provided with a through hole, and the upper frame 110 and the lower housing 120 are interconnected.

[0066] The upper frame 110 is connected to the lower housing 120 and the fixing member 310. The upper frame 110 is rotatably connected to one side of the upper baffle 210, and the other side of the upper baffle 210 is connected to the side baffle 220. The connecting arm 221 is rotatably connected to the rotating member 330, the rotating member 330 is connected to the electric push rod 320, and the electric push rod 320 is rotatably connected to the fixing member 310. The upper surface of the upper baffle 210 is connected to the directional camera 410, the searchlight 420, and the buzzer 700. The switch valve 520 is connected to the fire extinguisher 510 and the hose 530. The hose 530 is detachably connected to the nozzle 540. The fire extinguisher 510 and the controller 600 are located inside the housing assembly 100. The nozzle 540 is connected to the upper baffle 210 through a through hole. The controller 600 is electrically connected to the electric push rod 320, the directional camera 410, the searchlight 420, the switch valve 520, and the buzzer 700, respectively. The charging pile 800 is connected to the controller 600, the electric push rod 320, the directional camera 410, the searchlight 420, the switch valve 520, and the buzzer 700, respectively.

[0067] According to an embodiment of this utility model, a ground lock device with fire detection function can achieve at least the following effects: When there is no vehicle in the charging parking space, the deflecting camera 410 captures the license plate image of the vehicle. When the controller 600 recognizes the license plate number as an authorized license plate number, the electric push rod 320 drives the upper baffle 210 from an inclined state to a horizontal state to complete the descent movement of the upper baffle 210, so that the vehicle can smoothly drive into the charging parking space. After the vehicle is parked in the charging parking space, the camera direction of the deflecting camera 410 rotates to the battery area of ​​the vehicle chassis to monitor the battery status. When the controller 600 detects an abnormality in the battery area image, it activates the fire extinguisher 510 through the switch valve 520 to extinguish the fire. When the controller 600 identifies that a vehicle has left the charging space based on the battery area image, the electric push rod 320 drives the upper baffle 210 from a horizontal state to an inclined state to complete the upward movement of the lock body assembly 200, thereby forming a physical barrier in the charging space and preventing other unauthorized vehicles from entering.

[0068] As can be seen, the upper baffle 210 can be automatically raised and lowered through the combined action of various components, thus facilitating the parking of authorized vehicles; it can also monitor the battery status, thereby automatically extinguishing the fire when the battery catches fire, effectively reducing the property loss of the vehicle owner.
