Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging piles, specifically an intelligent charging device. Background Technology
[0002] Charging stations are infrastructure that provides electric power to electric vehicles, similar to gas stations for traditional gasoline vehicles, but they transmit electrical energy. According to the charging method, they are divided into AC charging stations and DC charging stations. According to the installation method, they are mainly divided into vertical charging stations and wall-mounted charging stations. Vertical charging stations do not need to be against a wall and are suitable for outdoor parking spaces and community parking spaces; wall-mounted charging stations must be fixed to a wall and are suitable for indoor and underground parking spaces.
[0003] However, because the charging gun cable for cars is quite long, it is prone to wear and tear when frequently plugged in and unplugged, as the cable tends to pile up on the ground. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides an intelligent charging device that solves the problems mentioned in the background.
[0005] This utility model provides the following technical solution: an intelligent charging device, including a charging pile, a charging gun is provided on one side of the charging pile, a movable sleeve hole is opened on the side surface of the charging pile, a storage mechanism is provided inside the charging pile, the storage mechanism includes: a swing rod and an upper connecting rod, a magnetic sleeve is installed on the outer side of the upper connecting rod, an electromagnet is installed on the inner side wall of the charging pile corresponding to the position of the magnetic sleeve, a rotating ear plate is provided below the end of the swing rod away from the upper connecting rod inside the charging pile, and a movable rotating shaft is installed between the swing rod and the rotating ear plate.
[0006] As a further embodiment of this utility model: a power socket is installed on the side surface of the charging pile at one end of the charging gun, and a hanging plug is installed above the movable sleeve hole on the side surface of the charging pile.
[0007] As a further improvement of this utility model: the lower end of the electromagnet is connected to a power line, and a control panel is installed on the front surface of the charging pile.
[0008] As a further improvement of this utility model: the swing rod is rotatably connected to the rotating ear plate through the movable shaft, and the inner diameter of the movable sleeve hole is greater than the outer diameter of the charging gun.
[0009] As a further improvement of this utility model, the length of the swing rod is greater than the width of the charging pile.
[0010] As a further improvement of this utility model, the movable sleeve hole is engaged with the hook-and-connection hole.
[0011] As a further improvement of this utility model, the magnetic sleeve is fixedly connected to the upper connecting rod.
[0012] As a further improvement of this utility model, both the control panel and the power supply line are connected to an external power source.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] Once charging is complete, the entire swing arm will swing inside the rotating ear plate via the movable pivot. The end of the swing arm with the magnetic sleeve will swing towards the electromagnet, pulling the charging gun inwards towards the charging station. The magnetic sleeve will then be attracted and locked by the electromagnet, preventing excessive cable exposure on the outside. Attached Figure Description

[0020] 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.
[0021] like Figure 1-4As shown, this embodiment provides an intelligent charging device, including a charging pile 1. A charging gun 4 is provided on one side of the charging pile 1. A movable sleeve hole 5 is opened on the side surface of the charging pile 1. A storage mechanism 7 is provided inside the charging pile 1. The storage mechanism 7 includes: a swing rod 701 and an upper connecting rod 704. The length of the swing rod 701 is greater than the width of the charging pile 1. A magnetic sleeve 705 is installed on the outer side of the upper connecting rod 704. The magnetic sleeve 705 is fixedly connected to the upper connecting rod 704. An electromagnet 101 is installed on the inner side wall of the charging pile 1 at the position corresponding to the position of the magnetic sleeve 705. A rotating ear plate 702 is provided below the end of the swing rod 701 away from the upper connecting rod 704 inside the charging pile 1. The swing rod 701 is rotatably connected to the rotating ear plate 702 through a movable shaft 703. The inner diameter of the movable sleeve hole 5 is greater than the outer diameter of the charging gun 4. A movable shaft 703 is installed between the swing rod 701 and the rotating ear plate 702.
[0022] like Figure 2-3 As shown, in this embodiment, a power socket 6 is installed on the side surface of the charging pile 1 at one end of the charging gun 4. A hanging socket 3 is installed above the movable sleeve hole 5 on the side surface of the charging pile 1. The movable sleeve hole 5 is engaged with the hanging socket 3. The lower end of the electromagnet 101 is connected to a power line 102. When the circuit of the charging gun 4 is connected, the power supply circuit of the power line 102 will be automatically cut off. Similarly, when the circuit to the charging gun 4 is cut off, the circuit of the power line 102 will be automatically connected. A control panel 2 is installed on the front surface of the charging pile 1. Both the control panel 2 and the power line 102 are externally powered.
[0023] The working principle of this utility model is as follows: During installation, the power supply line 102 and the power socket 6 are connected to the power supply circuit. Simultaneously, the charging gun 4 is inserted from the inside of the movable sleeve hole 5 into the charging pile 1, passes around the upper connecting rod 704, and then exits through the movable sleeve hole 5. When the movable sleeve hole 5 is inserted into the hanging socket 3, it is locked, and the charging gun 4 is not powered. When charging is required, the user unlocks the hanging socket 3's restriction on the charging gun 4 via the control screen 2, thus connecting the circuit of the charging gun 4. After the circuit of the charging gun 4 is connected, the power supply circuit of the power supply line 102 is automatically cut off. When the power supply line 102 is de-energized, the electromagnet 101 loses its magnetic effect, thus releasing the electromagnet 101 from the magnetic sleeve 705. After the charging gun 4 is attracted and locked, the user can start charging by pulling the charging gun 4. When charging is completed, the circuit of the charging gun 4 is cut off and the circuit of the power line 102 is automatically connected. The electromagnet 101 is energized and generates magnetism. The length of the swing rod 701 is set to be greater than the width of the charging pile 1. Therefore, the swing rod 701 will swing inside the rotating ear plate 702 through the movable shaft 703. The end of the swing rod 701 with the magnetic sleeve 705 swings towards the position of the electromagnet 101, pulling the charging gun 4 into the charging pile 1 and retracting it. The magnetic sleeve 705 is attracted and locked by the electromagnet 101.
