Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and more specifically, to a large-angle charging pile anti-collision device and method. Background Technology

[0002] With the promotion of electric vehicles, many areas have set up charging stations for electric vehicles. When users are charging, there are often many vehicles. When parking and charging, due to obstructed vision and other reasons, cars are prone to bumping into charging stations. This can easily damage the charging stations and the car's exterior, causing unnecessary trouble for users.

[0003] Currently, there are several common methods for preventing collisions with charging piles: 1. Reinforcing the charging pile itself by installing protective covers, buffer barriers, etc.; 2. Making the charging pile movable to avoid impacts; 3. Simultaneously setting up obstacles to directly impact the vehicle body or wheels to withstand the impact. The first method is effective for minor impacts but has limited practical significance. The second method, which involves moving the charging pile to avoid collisions, increases the difficulty of wiring and significantly reduces its stability. Moreover, the avoidance is mostly directional and difficult to cope with real-world scenarios involving large-angle (multiple-angle) impacts. The third method, which involves simply blocking the impact, can easily damage the vehicle and pose safety risks to the occupants. A more reasonable and safer anti-collision device and method for charging piles at large angles is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a large-angle charging pile anti-collision device and method, which addresses the above-mentioned deficiencies of the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A large-angle charging pile anti-collision device is constructed, comprising an anti-collision box buried in the ground in front of the charging pile and a vehicle sensor installed on the front surface of the charging pile. The upper surface of the anti-collision box is flush with the ground. Multiple support columns are arranged in a matrix inside the anti-collision box, and the top surfaces of the multiple support columns are combined to form the upper surface of the anti-collision box. Pressure sensors are installed on the top surfaces of the support columns. The anti-collision box also contains multiple support components that provide support force to the support columns one-to-one, as well as a drive controller. When the support components release their support on the support columns, the support columns can sink to a set height. The anti-collision box also contains an elastic reset component to reset the support columns after sinking. The vehicle sensor detects the vehicle. When the vehicle reaches the set safe parking and charging area, it sends a first warning sound. When the vehicle crosses the set safe parking and charging area, it sends a second warning sound and sends an anti-collision blocking signal to the drive controller. The drive controller collects data from the multiple pressure sensors to determine the current position of the four tires of the vehicle and sends commands to control the support components corresponding to the areas behind the four tires. After receiving the commands, the support components release their support on the corresponding support columns.

[0007] The large-angle charging pile anti-collision device of the present invention includes a support assembly comprising a plurality of positioning sleeves fixedly disposed within the anti-collision housing and correspondingly fitted onto the support column; the upper end of the support column extends beyond the positioning sleeves; a hydraulic buffer is provided at the inner bottom of the positioning sleeve to provide cushioning for the support column; the elastic reset assembly is a reset spring fitted onto the hydraulic buffer, the lower end of the reset spring being connected to the inner bottom of the positioning sleeve and the upper end being connected to the support column; a pin hole is provided on the outer surface of the positioning sleeve, and a slot corresponding to the pin hole is provided on the support column; the support assembly further includes a pin inserted into the pin hole and a lateral movement unit for driving the pin to move laterally; the support and release states of the support column are changed by inserting and withdrawing the pin into and out of the slot.

[0008] The large-angle charging pile anti-collision device of the present invention includes a lateral movement unit comprising a drive motor and a sliding plate laterally connected to the drive motor, the sliding plate being fixedly connected to the positioning sleeve; the movable end of the drive motor being coaxially fixedly connected to the pin; the inner surface of the pin hole being provided with an internal thread, and the outer surface of the pin being provided with an external thread that mates with the internal thread.

[0009] The large-angle charging pile anti-collision device of the present invention includes a sealed protective cover on the sliding plate covering the drive motor.

[0010] The large-angle charging pile anti-collision device of the present invention includes a blower cleaning unit on one side of the bottom of the anti-collision box and a garbage collection trough on the other side.

[0011] The large-angle charging pile anti-collision device of the present invention includes a power supply cable for supplying power to multiple support components and a drive controller embedded in the inner bottom of the anti-collision box.

[0012] A method for preventing collisions at large angle charging piles, applied to the aforementioned anti-collision device for large angle charging piles, is implemented as follows:

[0013] The vehicle sensor monitors vehicles approaching the charging station. When the vehicle reaches the designated safe parking and charging area, it sends a first alert sound to remind the driver that the safe charging location has been reached.

[0014] When the vehicle crosses the designated safe parking and charging area, the vehicle sensors emit a second warning sound and send a collision avoidance signal to the drive controller. The drive controller collects data from multiple pressure sensors to determine the current position of the vehicle's four tires and sends a command to control the support components corresponding to the areas behind the four tires. After receiving the command, the support components release the support force on the corresponding support columns, forming a recessable area corresponding to each of the four tires.

[0015] When the vehicle leaves the charging area of ​​the charging station, the vehicle sensor sends a reset signal to the drive controller; the drive controller sends a command to the support assembly, and the support assembly restores its support to the support column.

[0016] The beneficial effects of this invention are as follows: The vehicle sensor monitors vehicles approaching the charging station. When the vehicle reaches the designated safe charging area, it sends a first alert sound to remind the driver that the vehicle has reached a safe charging position. When the vehicle crosses the designated safe charging area, the vehicle sensor sends a second alert sound and a collision avoidance signal to the drive controller. The drive controller collects data from multiple pressure sensors to determine the current position of the vehicle's four tires and sends commands to control the support components corresponding to the areas behind the four tires. Upon receiving the commands, the support components release the support force on the corresponding support columns, forming indentable areas corresponding to each of the four tires. When the vehicle leaves the charging area of ​​the charging station, the vehicle sensor sends a reset signal to the drive controller. The drive controller then sends commands to control the support components. The component, which supports the support column, is triggered by vehicle sensing. After the vehicle's position is accurately located by multiple matrix-distributed pressure sensors, a recessable area is formed behind each wheel. When the vehicle continues to approach the charging station, all four wheels simultaneously enter the corresponding recessable area, thus preventing the vehicle from approaching further. When no vehicle enters the charging station, the support component will not sink, and people can pass normally. By applying the method of this application, safe parking and charging areas can be flexibly set according to actual needs (different vehicle models, sites, etc.). At the same time, it can accurately block four-wheel collisions for charging vehicles parked at multiple angles without damaging the vehicles, thus reasonably solving the problems that current anti-collision devices cannot solve.

[0019] Figure 2 This is a preferred embodiment of the large-angle charging pile anti-collision device of the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] The preferred embodiment of the large-angle charging pile anti-collision device of the present invention, such as Figure 1 As shown, see also Figure 2 The system includes a crash box 2 buried in the ground in front of the charging pile 1 and a vehicle sensor 3 installed on the front surface of the charging pile 1. The upper surface of the crash box 2 is flush with the ground. Multiple support columns 4 are arranged in a matrix inside the crash box 2. The top surfaces of the multiple support columns 4 are combined to form the upper surface of the crash box 2. Pressure sensors 40 are installed on the top surfaces of the support columns 4. Multiple support components 5 that provide support force to the support columns 4 are also installed inside the crash box 2. When the support components 5 release the support of the support columns 3, the support columns 3 can sink to a set height. An elastic reset component 6 is also installed inside the crash box 2 to reset the support columns 3 after sinking.

[0022] The vehicle sensor 3 senses the vehicle. When the vehicle reaches the set safe parking and charging area, it sends a first reminder sound. When the vehicle crosses the set safe parking and charging area, it sends a second reminder sound and sends a collision prevention signal to the drive controller. The drive controller collects data from multiple pressure sensors 40 to determine the current position of the four tires of the vehicle and sends a command to control the support components 5 corresponding to the area behind the four tires. After receiving the command, the support components 5 release the support of the corresponding support column 4.

[0023] The vehicle sensors monitor vehicles approaching the charging station. When the vehicle reaches the designated safe charging area, a first warning sound is emitted to alert the driver that the vehicle has reached a safe charging location. When the vehicle crosses the designated safe charging area, the vehicle sensors emit a second warning sound and send a collision avoidance signal to the drive controller. The drive controller collects data from multiple pressure sensors to determine the current position of the vehicle's four tires and sends commands to control the support components corresponding to the areas behind the four tires. Upon receiving the commands, the support components release the support force on the corresponding support columns, forming indentable areas corresponding to each of the four tires. When the vehicle leaves the charging area, the vehicle sensors send a reset signal to the drive controller. The drive controller then sends commands to the support components, which restore support to the support columns.

[0024] Triggered by vehicle sensing and with the precise location of the vehicle by multiple matrix-distributed pressure sensors, a concave area is formed behind each wheel. When the vehicle continues to approach the charging station, all four wheels will simultaneously enter the corresponding concave area, thus preventing the vehicle from getting closer. When no vehicle enters the charging station, the support will not sink, and people can pass through normally without being concave.

[0025] By applying the methods and approaches of this application, safe parking and charging areas can be flexibly set up according to actual needs (different vehicle models, sites, etc.). At the same time, it can accurately block four-wheel collisions for charging vehicles parked at multiple angles without causing damage to the vehicles, thus reasonably solving the problems that current collision avoidance devices cannot solve.

[0026] Preferably, the support assembly 5 includes multiple positioning sleeves 50 fixedly installed inside the anti-collision box 2, each corresponding to a support column 4; the upper end of the support column 4 extends beyond the positioning sleeves 50; the inner bottom of the positioning sleeves 50 is provided with a hydraulic buffer 51 to provide cushioning for the support column 4 (used to reduce the descent speed when the vehicle is squeezed, and to avoid danger caused by excessive falling speed when the vehicle contacts it); the elastic reset assembly 6 is a reset spring sleeved on the hydraulic buffer 51, the lower end of the reset spring is connected to the inner bottom of the positioning sleeves 50, and the upper end is connected to the support column 4; the outer surface of the positioning sleeves 50 is provided with pin holes 52, and the support column 4 is provided with slots 41 corresponding to the pin holes 52; the support assembly 5 also includes a pin 53 inserted into the pin holes 52 and a lateral movement unit 54 that drives the pin to move laterally; the support and release states of the support column 4 are changed by inserting and withdrawing the pin 53 into and out of the slot 41;

[0027] When pin 53 is inserted into slot 41, support column 4 is in a non-lowering state. A person passing over it will not trigger support column 4 to sink. When pin 53 is removed from slot 41, support column 4 is in a lowering state. If the vehicle continues to move towards the charging station, the vehicle will accurately contact the support column and trigger it to sink, forming a depression. For a vehicle slowly entering the charging position, the depression of the four wheels is enough to make the vehicle stop quickly and reverse, achieving the purpose of collision prevention without damaging the vehicle. When the vehicle needs to move out of the depression, it can drive forward with increased power to climb out of the depression. The overall structure is simple, low in cost, fast in locking and unlocking, reliable, and the support column has good operational stability.

[0028] Preferably, the lateral movement unit 54 includes a drive motor 540 and a sliding plate 541 that is laterally slidably connected to the drive motor. The sliding plate 541 is fixedly connected to the positioning sleeve 50. The movable end of the drive motor 540 is coaxially fixedly connected to the pin 53. The inner surface of the pin hole 52 is provided with an internal thread, and the outer surface of the pin 53 is provided with an external thread that mates with the internal thread. A sealing protective cover 542 is provided on the sliding plate 541, covering the drive motor 540. The drive motor drives the pin to rotate, and the threaded engagement between the pin and the pin hole drives the drive motor and the pin as a whole to move, thereby realizing the insertion and withdrawal of the pin 53 into and out of the slot 41. The overall structure is very compact and occupies little space. The external protective cover can provide good waterproof and dustproof protection for the motor. Preferably, the bottom of the anti-collision box 2 is embedded with a power supply cable for powering multiple support components and the drive controller.

[0029] Preferably, a blower cleaning unit 20 (which can be a blower, with the blower's air inlet 200 extending to the ground via a pipe) is provided on one side of the inner bottom of the anti-collision box 2, and a garbage collection trough 21 (which can be equipped with a movable cover 210 to open and close the collection trough) is provided on the other side. When cleaning is required, the blower cleaning unit is turned on to blow the dust and other debris inside to the garbage collection trough 21 at the other end, and then the garbage collection trough 21 can be cleaned manually.

[0030] A method for preventing collisions at large angle charging piles, applied to the aforementioned anti-collision device for large angle charging piles, is implemented as follows:

[0031] The vehicle sensor monitors vehicles approaching the charging station. When the vehicle reaches the designated safe parking and charging area, it sends a first alert sound to remind the driver that the safe charging location has been reached.

[0032] When the vehicle crosses the designated safe parking and charging area, the vehicle sensors emit a second warning sound and send a collision avoidance signal to the drive controller. The drive controller collects data from multiple pressure sensors to determine the current position of the vehicle's four tires and sends a command to control the support components corresponding to the areas behind the four tires. After receiving the command, the support components release the support force on the corresponding support columns, forming a recessable area corresponding to each of the four tires.

[0033] When the vehicle leaves the charging area of ​​the charging station, the vehicle's sensors send a reset signal to the drive controller; the drive controller sends a command to the support assembly, and the support assembly restores its support to the support column;

[0034] By applying the methods and approaches of this application, safe parking and charging areas can be flexibly set up according to actual needs (different vehicle models, sites, etc.). At the same time, it can accurately block four-wheel collisions for charging vehicles parked at multiple angles without causing damage to the vehicles, thus reasonably solving the problems that current collision avoidance devices cannot solve.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
