Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with intelligent avoidance and anti-collision functions and an operating method thereof. Background Art

[0002] As we all know, with the promotion of electric vehicles, the demand for charging is increasing, and a large number of charging piles have been built. In order to improve charging safety, we propose a charging pile and operation method with intelligent avoidance and collision avoidance functions.

[0003] After searching, the invention patent with Chinese patent application number CN202311503600.5 discloses a charging pile with anti-collision function, which is roughly described as including a charging pile, a base fixedly connected to the bottom of the charging pile, an alarm component for reminding the vehicle when it reaches the charging position, a protective component for protecting the charging pile when the vehicle is too close to the charging pile, and a lifting component for preventing the vehicle from retreating when the vehicle collides with the protective component and continues to retreat on the base. When in use, the protective plate is continuously extended upward by sliding the sliding rod 1 upward, thereby achieving that when the distance between the vehicle and the charging pile is too close, the protective component is first triggered to protect the charging pile to avoid damage to the charging pile caused by direct collision.

[0004] Although the above-mentioned existing technical solution can have the effect of warning and hindering vehicles approaching the charging pile, the method it adopts is to lift the rear wheels of the vehicle through a lifting component, thereby achieving limited parking of the vehicle. However, considering the actual situation of the vehicle, the driving forms include front-wheel drive, rear-wheel drive and four-wheel synchronous drive. Therefore, this rear wheel lifting method only has a practical effect on rear-wheel drive vehicles, and the effect on front-wheel drive and four-wheel synchronous drive vehicles is relatively weak.

[0012] Preferably, rainwater grates are provided on the plurality of communicating grooves.

[0013] A method for operating a charging pile with an intelligent collision avoidance function comprises the following steps: S1. Under normal operation, under the action of the linkage assembly, the central diagonal frame, central flat frame, side diagonal frame and side flat frame are in a state of gradual elevation. When a vehicle that needs to be charged enters the parking space, the wheels of the vehicle that enters the parking space first will first contact the limit rod, and the limit rod will form a limit position for the vehicle; S2. After the vehicle reaches a designated charging position within the parking space, the vehicle is positioned at the charging pile corresponding to the parking space. The charging cable on the charging pile is inserted into the vehicle, thereby achieving charging for the vehicle. S3. When the vehicle's parking limit bar fails to effectively stop the vehicle in the parking space due to the driver's driving error, the wheels of the vehicle that first enter the parking space will pass over the limit bar and enter the central diagonal rack, central flat rack, side diagonal rack, and side flat rack in sequence. The extent to which the wheels enter the central diagonal rack, central flat rack, side diagonal rack, and side flat rack is determined by the vehicle operator and the vehicle's condition. S4. When the vehicle's approach speed is too fast, due to inertia, the wheels will enter the central diagonal frame, central flat frame, side diagonal frame, and side flat frame to a greater extent. Conversely, the degree of entry will be less. Since the central diagonal frame, central flat frame, side diagonal frame, and side flat frame are in a state of rising in sequence, the energy required for the wheels to enter the central diagonal frame, central flat frame, side diagonal frame, and side flat frame also increases in sequence. S5. When the wheels enter the central inclined frame, central flat frame, side inclined frame, and side flat frame, due to the downward pressure of the wheels on the central inclined frame, central flat frame, side inclined frame, and side flat frame, the central inclined frame, central flat frame, side inclined frame, and side flat frame will synchronously lower their height in conjunction with the wheels that press down on them. Under the action of the linkage assembly, the lowered central inclined frame, central flat frame, side inclined frame, and side flat frame will push the charging pile relative to the parking space to ensure a safe distance between the charging pile and the vehicle.

[0014] Compared with the prior art, the present invention provides a charging pile and operation method with intelligent collision avoidance function, which has the following beneficial effects: (1) In the present invention, a parking assistance system adapted to the vehicle is formed by cooperating the central diagonal frame, the central flat frame, the side diagonal frame and the side flat frame, and the vehicle's auxiliary parking is achieved in the form of energy consumption.

[0015] (2) In the present invention, the charging pile can be adjusted relative to the parking space by sliding the charging pile on the parking space, so as to facilitate the avoidance adjustment of the charging pile relative to the vehicle.

[0016] (3) In the present invention, by designing the linkage components, the wheels enter the central inclined frame, central flat frame, side inclined frame and side flat frame, and the corresponding displacement is formed with the charging pile, so that a safe distance between the charging pile and the vehicle is maintained, thereby improving the operating safety of the charging pile.

[0022] In summary, the operation method of the charging pile with intelligent avoidance and anti-collision function includes the following steps: during construction, the top surface of the parking space 2 is flush with the ground surface. Under normal operation, under the action of the first elastic spring 17 and the second elastic spring 18 in the linkage assembly, the central inclined frame 5, the central flat frame 6, the side inclined frame 7 and the side flat frame 8 are in a state of gradually rising in sequence. When a vehicle that needs to be charged enters the parking space 2, the wheels of the vehicle that enters the parking space 2 first will first contact the limit rod 4, and the vehicle will be limited under the action of the limit rod 4. After the vehicle is limited in the parking space 2, it will reach the position where the charging pile 1 corresponding to the parking space 2 is adapted for charging. The charging line on the charging pile 1 and the charging pile 1 are connected The vehicle is adaptively inserted, thereby achieving adaptive charging for the vehicle. When the limit rod 4 does not form an effective stop limit for the vehicle in the parking space 2 due to the driving reasons of the driver, the wheels of the vehicle that first enters the parking space 2 will pass the limit rod 4 and enter the central inclined frame 5, the central flat frame 6, the side inclined frame 7 and the side flat frame 8 in sequence, and the degree to which the wheels enter the central inclined frame 5, the central flat frame 6, the side inclined frame 7 and the side flat frame 8 will be determined by the vehicle operator and the state of the vehicle. When the vehicle enters too fast, under the action of inertia, the degree to which the wheels enter the central inclined frame 5, the central flat frame 6, the side inclined frame 7 and the side flat frame 8 will be greater, otherwise the degree of entry will be smaller. , the central connecting flat frame 6, the side connecting oblique frame 7 and the side connecting flat frame 8 are in a state of rising in sequence, so the energy required for the wheels to enter the central connecting oblique frame 5, the central connecting flat frame 6, the side connecting oblique frame 7 and the side connecting flat frame 8 also increases in sequence. When the wheels enter the central connecting oblique frame 5, the central connecting flat frame 6, the side connecting oblique frame 7 and the side connecting flat frame 8, due to the downward pressure of the wheels on the central connecting oblique frame 5, the central connecting flat frame 6, the side connecting oblique frame 7 and the side connecting flat frame 8, the central connecting oblique frame 5, the central connecting flat frame 6, the side connecting oblique frame 7 and the side connecting flat frame will form a synchronous height reduction with the pressed wheels.
