Therefore, it should not be construed as a limitation to the present application. In addition, terms such as "horizontal", "vertical", "hanging" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined. In the description of the embodiments of the present application, "a plurality" means at least two.

[0031] Please refer to Figures 1 to 3 , this application provides a charging pile, which includes a charging gun 10, a housing 20, an inner support plate 30 and a movable door 40. The charging gun 10 is responsible for charging the battery of an electric vehicle, and includes a charging cable 11 and a charging head 12. The charging head 12 is used to insert into the charging interface of the electric vehicle to charge the battery. The charging cable 11 connects the charging head 12 to the main body of the charging pile and is used to transmit electric power.

[0032] The housing 20 is the outer shell of the entire charging pile, which plays a role in protecting the internal structure and beautifying the appearance. An opening 21 is provided on the housing 20, and a cavity is formed inside the opening 21, and this cavity will be used to accommodate the charging gun 10. The charging head 12 and part of the charging cable 11 of the charging gun 10 can extend into the cavity from the opening 21 to be placed inside the cavity. A card slot 22 is also provided at the lower end of the opening 21, and this card slot can be used to hold the charging cable 11 of the charging gun 10 to prevent it from falling. The material and structural design of the housing 20 need to consider factors such as durability, waterproof and dustproof, and anti-ultraviolet, to ensure that the charging pile can operate stably for a long time in various environments.

[0033] The inner support plate 30 is arranged inside the cavity and is used to hold the connection part of the charging head 12 and the charging cable 11 of the charging gun 10. When the charging gun 10 is inserted into the cavity from the opening 21, due to the relatively large self-weight of the charging cable 11 and the irregular shape of the charging head 12, there is a tendency to slide out of the opening under the action of gravity inside the cavity. In order to eliminate this tendency, the inner support plate 30 is provided. Since the diameter of the end of the charging head 12 connected to the charging cable 11 is larger than that of the charging cable 11, the setting of the inner support plate 30 can hold the charging head 12 when the charging gun 10 has a tendency to slide, eliminate its movement tendency, and keep the charging gun 10 stable in the cavity.

[0034] When the charging gun 10 is placed inside the cavity, in order to ensure that the charging gun 10 is isolated from the outside and avoid being eroded by direct sunlight, rainwater, etc., in this embodiment, a movable door 40 is further provided, and its function is to open or close the opening 21.

[0035] Specifically, when the charging gun 10 is not in use, the movable door 40 can be opened first, and the charging gun 10 is inserted into the cavity from the opening 21, and the charging gun 10 is fixed inside the cavity by using the card slot 22 at the opening 21 and the inner support plate 30 inside the cavity. At this time, as Figure 2 shown, then close the movable door 40 to play the roles of dust prevention, rain prevention, sun protection, etc. When the charging gun 10 needs to be used, as Figure 3 shown, open the movable door 40, and the charging gun 10 leaves the cavity from the opening 21, and the user can operate the charging gun 10 to charge the electric vehicle.

[0036] It is worth mentioning that an arc-shaped structure can also be set at the position of the lower end of the movable door 40 corresponding to the card slot 22. When the movable door 40 is closed, the arc-shaped structure will cooperate with the card slot 22 to form a hole allowing the charging cable 11 to extend out, maximizing the sealing effect of the movable door 40. In order to fit the shape of the cable, the card slot 22 can be a U-shaped groove. In addition, the movable door 40 can be opened and closed up and down as shown in the figure, or can be opened and closed left and right or in other ways. The movable door 40 can be manually opened or electrically driven to open.

[0037] In this embodiment of the charging pile, an opening is provided on the housing to form a cavity inside, and the cavity can be used to insert the charging gun. A card slot is provided at the opening, which cooperates with the inner support plate inside the cavity to fix the charging gun inside the cavity. An activity door is also provided at the opening, which can open or close the opening as needed, so that the charging gun can be flexibly taken out of the cavity and can also be isolated from the outside, playing the roles of sun protection, waterproofing, and dustproofing. The charging pile in this embodiment can greatly extend the service life of the charging gun, reduce the maintenance cost, and also avoid the occurrence of short circuits or damages in the internal circuit of the charging gun, thereby generating the risk of electric shock.

[0038] In one of the embodiments, please refer to Figures 1 to 4 , the charging pile further includes a driving module 50, and the driving module 50 is mechanically connected to the movable door 40 and is used to drive the movable door 40 to open the opening 21 when receiving an opening signal, and drive the movable door 40 to close the opening 21 when receiving a closing signal.

[0039] It can be understood that the movable door 40 in this embodiment is electrically driven, and its power source is the driving module 50. When the driving module 50 receives the opening signal, it generates power and transmits it to the movable door 40 through mechanical connection, prompting the movable door 40 to open the opening 21. When the closing signal is received, the driving module 50 acts again to drive the movable door 40 to close the opening 21. This process is like an automated door control system. The opening signal is like an instruction telling the driving module 50 to perform the opening action, while the closing signal instructs the driving module 50 to perform the closing operation.

[0040] In one embodiment, please refer to Figures 1 to 4 , when a user needs to use the charging pile to charge an electric vehicle, identity verification needs to be carried out first. Therefore, the charging pile further includes an identity verification module 60. The identity verification module 60 is electrically connected to the driving module 50 and is used to verify the customer's identity and send an opening signal when the verification is passed.

[0041] It can be understood that the main function of the identity verification module 60 in the charging pile system is to verify the customer's identity. When a user needs to use the charging pile, they will provide identity information to the identity verification module 60 in a certain way, such as swiping a card, entering an account password, using a mobile phone APP to scan a code, scanning the user's face information, etc. The specific form of the identity verification module 60 corresponding to different verification methods is different. The identity verification module 60 corresponding to swiping a card includes a card reader. The identity verification module 60 corresponding to using a mobile phone APP to scan a code and entering an account password includes a touch screen 61. The identity verification module 60 corresponding to scanning the user's face information includes a camera 62. These identity information can be transmitted to the background server for verification to determine whether the user has the permission to use the charging pile. But after the verification is passed, the identity verification module 60 will send an opening signal to the driving module 50. After receiving this signal, the driving module 50 drives the movable door 40 to open the opening 21, allowing the user to take out the charging gun 10 for charging operations.

[0042] In one embodiment, please refer to Figures 1 to 4 , the charging pile further includes a locking module 70. The locking module 70 is arranged at the opening 21 and is electrically connected to the identity verification module 60. It is used to lock the position of the movable door 40 when the movable door 40 closes the opening 21 and is used to unlock when receiving the opening signal.

[0043] It can be understood that, in order to prevent unauthorized opening, the embodiment of the present application further provides a locking module 70. When the movable door 40 closes the opening 21, the locking module 70 locks the position of the movable door 40, so that the movable door 40 cannot be opened, ensuring that the charging gun 10 and other devices inside the charging pile are properly protected. However, when the authentication module 60 passes the authentication, it will send an opening signal. On the one hand, the opening signal can instruct the driving module 50 to drive the movable door 40 to open. On the other hand, it instructs the locking module 70 to unlock, so that the movable door 40 can be opened normally. The locking module 70 generally includes an electromagnet and a power supply unit. The power supply unit supplies power to the electromagnet to generate magnetic force, which attracts the iron parts arranged on the movable door 40, thereby realizing locking. The electromagnet of the locking module 70 is generally in an energized state, attracting the iron parts on the movable door 40 to prevent the movable door 40 from being accidentally opened. When the user needs to use the charging pile, the user conducts identity authentication through the authentication module 60. If the authentication is passed, the authentication module 60 sends an opening signal to the locking module 70 and the driving module 50. The power supply unit of the locking module 70 stops supplying power, the electromagnet loses magnetic force, and the locking of the movable door 40 is released. At the same time, the driving module 50 drives the movable door 40 to open the opening 21, and the user can take out the charging gun 10 to charge. This locking mechanism can effectively prevent malicious damage and unauthorized use, improving the safety and reliability of the charging pile.

[0044] In one embodiment, please refer to Figures 1 to 4 , the charging pile further includes an in-position detection module 80 and a timing module 81. The in-position detection module 80 is arranged in the cavity and is electrically connected to the timing module 81, and is used for sending an in-position signal when the charging gun 10 is not pulled out, and sending an out-of-position signal when the charging gun 10 is pulled out. The timing module 81 is electrically connected to the driving module 50 and the authentication module 60, and is used for starting timing when receiving the opening signal, stopping timing when receiving the out-of-position signal, and outputting a closing signal when the timing reaches a preset time threshold.

[0045] It can be understood that the in-place detection module 80 plays an important role in the charging pile. It is arranged in the cavity of the charging pile and can detect in real time whether the charging gun 10 is pulled out. When the charging gun 10 is not pulled out, the in-place detection module 80 sends an in-place signal; when the charging gun 10 is pulled out, it sends a not-in-place signal. The timing module 81 is electrically connected to the in-place detection module 80 and starts timing when it receives the start signal. This means that when the user passes the authentication through the authentication module 60 and the access door 40 is opened, the timing module 81 starts timing. The timing will continue until the in-place detection module 80 detects that the charging gun 10 is pulled out and sends a not-in-place signal to the timing module 81, then the timing module 81 stops timing. If the timing of the timing module 81 reaches the preset time threshold, it means that after the access door 40 is opened, the user has not taken out the charging gun 10 for a long time. At this time, the timing module 81 outputs a closing signal to the driving module 50. After receiving the closing signal, the driving module 50 drives the access door 40 to close the opening 21 to protect the internal structure of the charging pile. The user must re-authenticate to continue taking the gun at this time.

[0046] In one embodiment, the timing module 81 may be composed of a microprocessor and a clock circuit. When receiving the start signal, the microprocessor starts the clock circuit to start timing and stores the timing result in the internal memory. During the timing process, the microprocessor continuously monitors the signal from the in-place detection module 80. If it receives a not-in-place signal, the microprocessor stops the timing of the clock circuit and compares the timing result with the preset time threshold. If the timing reaches the preset time threshold, the microprocessor outputs a closing signal to the driving module 50 to drive the access door to close the opening. If the timing does not reach the preset time threshold, the microprocessor continues to wait for the input of other signals.

[0047] In one embodiment, please refer to Figures 1 to 3 , the in-place detection module 80 includes a pressure sensor, and the pressure sensor is arranged at the position on the inner support plate 30 in contact with the charging gun 10. It can be understood that the pressure sensor is arranged at the position on the inner support plate 30 in contact with the charging gun 10, so that when the charging gun 10 is placed on the inner support plate 30, it will exert a certain pressure on the pressure sensor. The pressure sensor generates a corresponding electrical signal according to the magnitude of the pressure received. If the charging gun 10 is in the correct position, the pressure sensor continuously outputs a signal indicating that the charging gun 10 is in place. When the charging gun 10 is pulled out, the pressure received by the pressure sensor disappears, and at this time it sends a not-in-place signal. The method of in-place detection through the pressure sensor is accurate and reliable and can timely reflect the state change of the charging gun 10.

[0048] In one embodiment, please refer to Figures 1 to 4, the charging pile further includes a prompting module 90. The prompting module 90 is electrically connected to the in-position detection module 80 and is configured to issue a prompt when receiving an out-of-position signal in case of charging completion. The prompting module 90 plays a role of reminding the user in the charging pile system. When the charging is completed, the in-position detection module 80 will send a signal according to the state of the charging gun 10. If an out-of-position signal is received, it indicates that the charging gun 10 may be forgotten by the user and not put back in place. At this time, the prompting module 90 will issue a prompt to remind the user to pay attention to putting the charging gun 10 back into the cavity. The prompting module 90 can adopt various forms. For example, it can use sound prompting to emit a specific alarm sound to remind the user that the charging gun 10 is not put back; or it can use light prompting to attract the user's attention through a flashing indicator light. The setting of the prompting module 90 can effectively prevent the user from forgetting to put the charging gun 10 back due to negligence, improving the convenience and safety of using the charging pile.

[0049] Finally, it should also be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
