Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a ground-mounted DC charging pile. Background Technology

[0002] Ground-mounted DC charging stations are installed directly on the ground and quickly charge the power batteries of electric vehicles by outputting DC power.

[0003] Because floor-mounted DC charging stations are installed directly on the ground, the cable is close to the ground, and the charging cable is relatively long, with a portion of the cable dangling and in direct contact with the ground. The ground is prone to water, oil, or other corrosive chemicals, which can corrode the cable. Furthermore, when retrieving the charging gun, the cable needs to be dragged, inevitably causing mechanical friction with the ground. Over time, this leads to wear and tear on the cable, reducing its lifespan and safety. Therefore, those skilled in the art have developed floor-mounted DC charging stations to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to provide a ground-mounted DC charging pile to solve the following technical problems:

[0005] How to prevent the charging cables of ground-mounted charging piles from being worn and corroded, and to improve their service life.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A ground-mounted DC charging pile includes a charging pile body, which has two gun supports, each of which is connected to a charging gun. The charging guns are electrically connected to the charging pile body via cables. A mounting base is fixed to the upper end of the charging pile body, and hanging arms are symmetrically connected to both sides of the mounting base. The hanging arms are used to suspend cables.

[0008] The suspension arm includes a rotating base, with a first swing arm rotatably connected to the outer end of the rotating base, a second swing arm rotatably connected to the end of the first swing arm, and a connecting sleeve rotatably connected to the lower side of the end of the second swing arm. The connecting sleeve is fixedly sleeved on the outer end near the connection between the cable and the charging pile body.

[0009] Furthermore, the mounting base includes a base body, which is fixedly connected to the upper end face of the charging pile body. Grooves are provided on both sides of the base body, and the swing arm can be retracted into the groove.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figures 1 to 3 As shown, the ground-mounted DC charging pile in this embodiment of the present invention includes a charging pile body 1, which has two gun supports 6, each of which is connected to a charging gun 2. The charging gun 2 is electrically connected to the charging pile body 1 via a cable 3. A mounting base 4 is fixed at the upper end of the charging pile body 1, and hanging arms 5 are symmetrically connected to both sides of the mounting base 4. The hanging arms 5 are used to hang the cable 3.

[0023] Specifically, the suspension arm 5 includes a rotating base 51, with a first swing arm 52 rotatably connected to the outer end of the rotating base 51, a second swing arm 53 rotatably connected to the end of the first swing arm 52, and a connecting sleeve 54 rotatably connected to the lower side of the end of the second swing arm 53. The connecting sleeve 54 is fixedly sleeved on the outer end near the connection between the cable 3 and the charging pile body 1. By setting up the suspension arm 5, the cable 3 can be suspended, so that the cable 3 is kept at a certain distance from the ground and does not directly contact the ground, thereby preventing the cable 3 from contacting water, oil or other chemicals that may be present on the ground, reducing the possibility of corrosion of the cable 3. At the same time, it can also prevent the cable 3 from mechanically rubbing against the ground, protecting the cable 3 from wear and increasing the service life of the cable.

[0024] The swing arms 52 and 53, as well as the connecting sleeve 54, are all rotatable and highly flexible. When using the charging gun 2, the user can freely pull the cable 3 for charging. There are few restrictions on the freedom of the cable 3. The connecting sleeve 54 can always follow the movement of the cable 3 to ensure that the cable 3 is suspended and does not come into contact with the ground.

[0025] In this embodiment, the connecting sleeve 54 is arc-shaped. Since the cable 3 will bend into an arc shape after bending, setting the connecting sleeve 54 to an arc shape can better fit the shape of the cable 3 after bending, thereby preventing creases from appearing at the edge of the cable and the connecting sleeve 54, which would cause the cable 3 to break.

[0026] In this embodiment, the mounting base 4 includes a base body 41, which is fixedly connected to the upper end face of the charging pile body 1. Both sides of the base body 41 are provided with grooves, and the swing arm 52 can be retracted into the groove. The rotating base 51 is fixedly connected to the front side of the groove. The rear side of both grooves is fixedly connected with a buffer component 7. The grooves facilitate the retraction of the swing arm 52 after use. The buffer component 7 can play a buffering role when the swing arm 52 is retracted, preventing direct mechanical collision.

[0027] Specifically, the buffer assembly 7 includes a mounting sleeve 71 fixed by bolts and a groove. A contact head 72 extending out of the mounting sleeve 71 is slidably sleeved inside the mounting sleeve 71. The outer end of the contact head 72 contacts the swing arm 52. A spring 73 is provided inside the mounting sleeve 71, and the spring 73 abuts against the contact head 72. A limit rod 74 is fixedly connected to the middle of the interior of the mounting sleeve 71. The contact head 72 is slidably sleeved with the limit rod 74. When the swing arm 52 returns to its original position, it will first contact the contact head 72, pressing down the contact head 72, causing the spring 73 to deform and absorb a certain impact force. The outer end of the limit rod 74 is an outwardly expanding disc shape, which can limit the contact head 72 and prevent the contact head 72 from coming out.

[0028] As one embodiment of this utility model, a cavity is provided in the middle of the seat body 41, and a crossbeam 42 is fixedly connected inside the cavity. Two lifting rings 43 are fixedly connected to the upper end face of the crossbeam 42. A top cover 44 is fixedly connected to the upper end face of the seat body 41. An opening is provided in the middle of the top cover 44. The crossbeam 42 and lifting rings 43 facilitate the hoisting of the charging pile using lifting equipment.

[0029] Additionally, it should be noted that the internal structure of the charging pile body 1 adopts the existing DC charging pile structure, which will not be elaborated here.

[0030] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
