Description

Technical Field

[0001] This utility model belongs to the technical field of electric vehicle charging equipment, and specifically relates to a reusable automatic power-off charging system. Background Technology

[0002] Existing electric vehicle charging systems suffer from significant drawbacks, including fixed charging sockets, limited charging cable length, and the presence of large vehicles occupying charging spots, impacting charging flexibility and efficiency. Firstly, charging sockets are typically fixed in specific locations, and the charging cables are short, forcing vehicles to park near the sockets to charge. When large tricycles or electric vehicles occupy charging spots, their size often blocks or occupies multiple charging sockets, making it difficult for subsequent vehicles to find suitable charging locations, thus reducing charging resource utilization. Furthermore, if a charging socket is damaged, vehicles parked at that location cannot easily move to other available sockets due to limited charging cable length, causing charging interruptions or delays and affecting the user experience.

[0003] The root of these problems lies in the lack of flexibility and redundancy in the design of the charging system, which fails to adequately consider the parking needs of different vehicle models and the fault tolerance of the charging infrastructure. Conventional solutions include increasing the number of charging outlets. However, these methods also have drawbacks: increasing the number of charging outlets requires more space and financial investment, which is difficult to implement in situations with limited space. Therefore, we aim to design a charging system with a novel structure to address this issue. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reusable automatic power-off charging system to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a reusable automatic power-off charging system, comprising: a charging rack, wherein multiple movable sockets for charging electric vehicles are slidably installed on the front side of the upper end of the charging rack, the charging rack includes support legs and a charging pile, multiple support legs for support are welded to the lower end of the charging pile, a main power supply line for power supply is installed inside the charging pile, and a controller for controlling automatic power-off and power supply for card swiping and code scanning is fixed in the middle of the upper end of the charging pile;

[0006] The movable socket includes a housing, with the socket body located at the rear center of the housing and a five-hole socket at the front. In actual use, the controller controls a single movable socket through a solid-state relay and a current detection module, thereby automatically realizing power outage, power supply interruption, and power failure protection.

[0007] In a preferred embodiment, the front surface of the charging pile is recessed in the middle to form a sliding groove, and the rear surface of the sliding groove extends backward to form multiple through grooves of equal length and spacing. The rear end of the charging pile is provided with an inner cavity for installing the main power supply line.

[0008] In a preferred embodiment, the through groove is connected to the front end of the inner cavity, and the cross-sectional dimensions and structure of the socket body are matched with the cross-sectional dimensions and structure of the sliding groove and the through groove. The rear end of the socket body is slidably connected to the inside of the through groove.

[0009] In a preferred embodiment, the main power supply line is provided with a plurality of equally spaced spring-type branch lines on the side near the through slot, and the number and distribution position of the spring-type branch lines match the number and distribution position of the socket body. The spring-type branch lines are electrically connected to the rear end of the socket body, and a baffle is provided between every two spring-type branch lines to fix the main power supply line and to shield the spring-type branch lines to prevent them from tangling.

[0010] In a preferred embodiment, the upper and lower sides of the front surface of the charging pile are recessed to form a second groove. The left and right ends of the charging pile are respectively fixed with an end plate by bolts. A guide rod is fixed inside each second groove. Multiple limiting blocks for limiting the movement of the movable socket are equally spaced inside each second groove.

[0011] In a preferred embodiment, the rear side of each limiting block is recessed forward to form a U-shaped relief groove for fixing the guide rod. Each limiting block is fixedly connected to the charging pile with screws. In actual use, the distance of the limiting block can be set according to the requirements. The limiting block can limit the movement of the socket to prevent it from being broken and damaged due to excessive pulling of the spring-type branch line.

[0012] In a preferred embodiment, the distance between two adjacent movable sockets is 50cm, the length of the through slot is 25cm, and a movable socket is slidably installed on the front middle side of each through slot.

[0013] In a preferred embodiment, a guide block is provided on the upper and lower sides of the rear end of the cover, and each guide block forms a through hole from left to right. The cross-sectional structure and size of the guide block are matched with the cross-sectional structure and size of the slide groove. The two guide blocks are slidably connected to the guide rod inside the slide groove through the through hole.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting up a new type of charging pile and movable socket, and adding limit blocks and spring-type branch lines, the traditional fixed socket design is broken, which solves the problem that large-volume tricycles or electric vehicles occupy the charging position, making it difficult for subsequent vehicles to find a suitable charging position, thus reducing the utilization rate of charging resources. This allows users to charge flexibly according to their needs, which helps to improve the charging utilization rate of multiple movable sockets. The movable socket enables the entire charging system to achieve a revolving charging mode, no longer limited to the fixed socket fixed-point charging method.

[0015] The guide block on the cover slides on the guide rod through the through hole. Under the combined action of the guide rod and the slide groove, it slides stably, avoiding damage caused by unstable movement of the movable socket when it moves. The limit block can limit the movable socket and prevent the spring-type branch wire from being pulled and broken due to excessive movement of the movable socket by the user.

[0023] 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.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a reusable automatic power-off charging system, including: a charging rack 100, with multiple movable sockets 200 for charging electric vehicles slidably installed on the front side of the upper end of the charging rack 100, the charging rack 100 including support legs 110 and charging piles 120, with multiple support legs 110 welded to the lower end of the charging piles 120, a main power supply line 130 for power supply installed inside the charging piles 120, and a controller for controlling automatic power-off and power supply for card swiping and code scanning fixed in the middle of the upper end of the charging piles 120;

[0025] The movable socket 200 includes a housing 210, with a socket body 230 located at the rear center of the housing 210 and a five-hole socket at the front. In actual use, the controller controls a single movable socket 200 through a solid-state relay and a current detection module, thereby automatically realizing power outage, power supply interruption, and power failure protection.

[0026] Please see Figures 1 to 4 The front surface of the charging pile 120 is recessed in the middle to form a groove 123. The rear surface of the groove 123 extends backward to form multiple through grooves 122 of equal length and spacing. The rear end of the charging pile 120 is provided with an inner cavity 121 for installing the main power supply line 130.

[0027] The through groove 122 is connected to the front end of the inner cavity 121. The cross-sectional dimensions and structure of the socket body 230 are matched with the cross-sectional dimensions and structure of the slide groove 123 and the through groove 122. The rear end of the socket body 230 is slidably connected to the inside of the through groove 122.

[0028] On the side of the main power supply line 130 near the through groove 122, there are multiple spring-type branch lines 140 distributed at equal intervals. The number and distribution of the spring-type branch lines 140 match the number and distribution of the socket body 230. The spring-type branch lines 140 are electrically connected to the rear end of the socket body 230. A baffle is provided between every two spring-type branch lines 140 to fix the main power supply line 130 and to shield the spring-type branch lines 140 to prevent them from getting tangled.

[0029] As the first embodiment of this utility model, by setting up a new type of charging pile 120 and a movable socket 200, and adding a limiting block 150 and a spring-type branch line 140, in actual use, if it is necessary to move the movable socket 200, the user only needs to move the movable socket 200 located in front of the charging pile 120, and the movable socket 200 in that position will follow the movement until it reaches the desired position (this position cannot exceed the upper limit of the length of the through groove 122). The movable socket 200, together with the new structure of the charging pile 120, can realize the need for flexible charging, breaking the traditional fixed socket design, and solving the problem that large tricycles or electric vehicles occupy the charging position, making it difficult for subsequent vehicles to find a suitable charging position, thus reducing the utilization rate of charging resources. This allows users to charge flexibly according to their needs, which helps to improve the charging utilization rate of multiple movable sockets 200. The movable socket 200 enables the entire charging system to realize a revolving charging mode, no longer limited to the fixed socket fixed-point charging method.

[0030] Please see Figures 2 to 4 The upper and lower sides of the front surface of the charging pile 120 are recessed to form a second groove. The left and right ends of the charging pile 120 are respectively fixed with an end plate by bolts. A guide rod 160 is fixed inside each second groove. Multiple limit blocks 150 for limiting the movement of the movable socket 200 are equally spaced inside each second groove.

[0031] Each limiting block 150 has a forward-recessed rear side forming a U-shaped relief groove 151 for fixing the guide rod 160. Each limiting block 150 is fixedly connected to the charging pile 120 with screws 124. In actual use, the limiting block 150 can be set at a distance according to requirements. The limiting block 150 can limit the movable socket 200 to prevent it from being broken and damaged due to excessive pulling of the spring-type branch line 140.

[0032] The distance between two adjacent movable sockets 200 is 50cm, the length of the through groove 122 is 25cm, and a movable socket 200 is slidably installed on the front side of the middle of each through groove 122.

[0033] A guide block 220 is provided on the upper and lower sides of the rear end of the cover 210. Each guide block 220 forms a through hole 221 from left to right. The cross-sectional structure and size of the guide block 220 are matched with the cross-sectional structure and size of the slide groove 2. The two guide blocks 220 are slidably connected to the guide rod 160 inside the slide groove 2 through the through hole 221.

[0034] As a second embodiment of this utility model, based on the first embodiment described above, during the movement of the movable socket 200, the guide block 220 on the cover 210 slides on the guide rod 160 through the through hole 221. Under the combined action of the guide rod 160 and the slide groove, the movable socket 200 slides stably, avoiding damage caused by unstable movement during movement, which helps to improve the service life of the movable socket 200. The limiting block 150 can limit the movable socket 200, preventing the user from excessively moving the movable socket 200, which could cause the spring-type branch wire 140 to be pulled and broken.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
