Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a portable charging pile with retractable cable. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform operations such as selecting the charging method, charging time, and printing cost data. The charging pile display screen can display data such as charging amount, cost, and charging time.

[0003] Existing charging devices have a winding mechanism inside the charging station to facilitate the winding of the charging cable. However, in actual operation, the charging cable is taken out of the charging station and then connected to the device that needs to be charged. During this process, the charging cable is exposed to the outside world and is easily pulled by external objects or human force. After long-term use, the connection between the charging cable and the charging station body is prone to breakage. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a portable charging station that clamps the charging cable during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable charging pile with cable retraction includes a charging pile body, several cable retraction mechanisms disposed within the charging pile body, and multiple sets of limiting mechanisms that pass through one side of the charging pile body and cooperate with the corresponding cable retraction mechanisms to limit the charging cable. Each set of limiting mechanisms consists of two sets of mutually interlocking limiting components. Each set of limiting mechanisms includes a protective half-shell affixed to the outer wall of the charging pile body and having a window in the middle, a circumferentially rotatable rotating rod horizontally installed in the middle of the window, a rotating clamping plate vertically fixed to the outside of the rotating rod with its upper part inside the window and its lower part extending to the outside of the window, and an elastic member fixed between the lower part of the rotating clamping plate and the side wall of the charging pile body.

[0007] More preferably, each set of the cable take-up mechanism includes a mounting base fixed inside the charging pile body, a circumferentially rotatable rotating shaft located inside the mounting base, a drive motor fixed to one side of the mounting base with its drive end passing through the side wall of the mounting base and fixed to the shaft end of the rotating shaft, and a fixing sleeve fixed outside the rotating shaft and fixedly connected to the charging cable.

[0008] More preferably, each protective half-shell has a guide half-sleeve that gradually slopes inward from front to back on its inner front side; the guide half-rings of the two protective half-shells are spliced ​​together to form a complete guide sleeve.

[0009] More preferably, a wiper half-ring is fixedly provided on the inner side of the rear end of each of the guide half-shells; the two protective half-shells are spliced ​​together to form a complete wiper ring.

[0010] Even better, the inner side of each rotating clamping plate is covered with an anti-wear layer.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, the charging cable is clamped by the front end of the two rotating clamping plates, which can minimize the possibility of the charging cable breaking between the charging cable and the charging pile body when the charging cable is exposed to the outside world and is pulled by external objects or human force, thus extending the service life of the device.

[0013] 2. In this utility model, it is only necessary to press and rotate the tail end of the clamping plate, and the charging cable can be clamped or released by the elastic force of the elastic element, which is simple to operate. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] A portable charging station with cable retraction includes a charging station body 1, several cable retraction mechanisms 2 disposed within the charging station body 1, and multiple sets of limiting mechanisms 3 that pass through one side of the charging station body 1 and cooperate with the corresponding cable retraction mechanism 2 to limit the charging cable. Each set of limiting mechanisms 3 consists of two sets of limiting components 4 that are interlocked with each other. Each set of limiting mechanisms 3 includes a protective half-shell 41 attached to the outer wall of the charging station body 1 and having a window 413 in the middle, a rotating rod 42 that is rotatable in the circumference and horizontally installed in the middle of the window 413, a rotating clamping plate 43 that is vertically fixed to the outside of the rotating rod 42 and has its upper part located inside the window 413 and its lower part extending to the outside of the window 413, and an elastic member 44 fixed between the lower part of the rotating clamping plate 43 and the side wall of the charging station body 1.

[0024] By pressing the tail end of the rotating clamping plate 43, the rotating clamping plate 43 drives the rotating rod 42 to rotate, so that the inner side of the front end of the rotating clamping plate 43 is flush with the inner side of the protective half shell 41. This facilitates the sliding of the charging cable located in the two protective half shells 41 within the protective shell formed after the two protective half shells 41 are joined together, thereby realizing the release and retraction of the charging cable. When the charging cable is pulled out for use, the pressure of the tail end of the rotating clamping plate 43 is released, causing the upper end of the rotating clamping plate 43 to rotate towards the charging cable side, and the charging cable is clamped by the two rotating clamping plates.

[0025] As a possible implementation of this solution, preferably, each set of winding mechanisms 2 includes a mounting base 21 fixed inside the charging pile body 1, a circumferentially rotatable rotating shaft 22 disposed inside the mounting base 21, a drive motor 23 fixed to one side of the mounting base 21 with its drive end passing through the side wall of the mounting base 21 and fixed to the shaft end of the rotating shaft 22, and a fixing sleeve 24 fixed outside the rotating shaft 22 and fixedly connected to the charging cable; the drive motor 23 drives the rotating shaft 22 to rotate forward, thereby driving the charging cable to wind onto the rotating shaft 22, so as to realize the rapid winding of the charging cable. When it is necessary to unwind the charging cable, the drive motor 23 only needs to be reversed.

[0026] As a possible implementation of this solution, preferably, each protective half-shell 41 has a guide half-sleeve 411 that gradually slopes inward from front to back on its inner front side; the guide half-rings of the two protective half-shells 41 are spliced ​​together to form a complete guide sleeve; the guide sleeve can guide the charging cable and at the same time minimize the wear of the charging cable during the charging and discharging process.

[0027] As a possible implementation of this solution, preferably, a wiper half-ring 412 is fixedly provided on the inner side of the rear end of each of the guide half-shells 411; the two protective half-shells 41 are spliced ​​together to form a complete wiper ring; the wiper ring can be used to wipe away debris and rainwater attached to the charging cable in rainy weather.

[0028] As a possible implementation of this solution, preferably, each rotating clamping plate 43 has an anti-wear layer 431 on its inner side; the anti-wear layer 13 minimizes the wear of the rotating clamping plate 43 during clamping.

[0029] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
