Description

Technical Field

[0002] Multi-story parking garages are a major means of solving the parking problem in cities. In recent years, the number of new energy vehicles has increased rapidly, and multi-story parking garages with charging functions have gradually become popular. To facilitate parking on the upper level of a multi-story parking garage, at least one transverse parking space will be set up on the first floor of the multi-story parking garage, and a car loading tray will be set on the transverse parking space. When a vehicle is parked / picked up on the upper or lower floor, the car loading tray will move to the first floor to avoid the parking space directly above or below, and it needs to move left and right frequently to avoid it.

[0003] This requires that the car tray located on the first floor for charging needs to move the charging gun frequently left and right. When the car tray is far away from the charging pile, the charging gun moves a long distance, causing the charging gun wire to frequently drag on the ground and cause friction, which is very easy to be damaged and cause leakage, increasing the cost of use while increasing safety hazards; at the same time, even if a protective shell is set on the outside of the charging gun wire, the charging gun wire is easy to bend during the dragging process. After long-term use, the internal cable of the charging gun wire is further damaged, reducing the overall service life, increasing maintenance and repair costs, and cannot meet the needs of safe and reliable charging.

DETAILED DESCRIPTION

[0019] refer to Figure 1, although there is currently a use of a drag chain 710 to protect the charging gun line, and at the same time cooperate with the extension and contraction of the rocker arm 700 to drive the charging gun line to move with the vehicle loading tray 600; however, due to the complex parking environment, vehicles driving in will carry more dust and gravel, which will increase the wear of the drag chain 710 and reduce its service life, thereby making the movement of the charging gun line unstable and reliable, and it is easy to be damaged in the process of following the movement of the vehicle loading tray 600; and after the drag chain 710 is set, it needs to be located on one side of the transverse parking space to facilitate the movement of the drag chain 710, so the length of the charging gun line needs to exceed the maximum length of the vehicle loading tray 600 The lateral movement distance increases with the increase of charging power, and the diameter and cost of the charging gun line also increase accordingly. The use of an overly long charging gun line increases the investment cost and the cost of subsequent maintenance and replacement. Moreover, as the diameter of the charging gun line increases, the bending radius of the drag chain also increases, which increases the vertical height of the drag chain 710. At the same time, since the rocker arm 700 is located at the rear of the vehicle loading pallet 600, this increases the risk of scratches, collisions and crushing of the drag chain 710 and the rocker arm 700 when the vehicle is parked on the vehicle loading pallet 600, which increases the difficulty of parking and easily makes the lateral movement parking space vacant, resulting in a waste of resources.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] refer to Figure 2 The present invention provides a charging pile gun line protection device, which is arranged between a vehicle loading tray 600 and a charging pile 500, and includes a first swing arm 100 and a second swing arm 200; wherein, one end of the first swing arm 100 is close to the charging pile 500 and is rotatably connected to the ground, the other end of the first swing arm 100 is rotatably connected to one end of the second swing arm 200, and the other end of the second swing arm 200 is close to the vehicle loading tray 600 and is rotatably connected to the vehicle loading tray 600; the charging gun line is arranged in the first swing arm 100 and the second swing arm 200, so as to protect the charging gun line.

[0022] At this time, the charging pile gun line protection device is horizontally arranged on the ground, and its height is less than the chassis height of the vehicle, which can avoid scratches or collisions with the vehicle when parking. Even when the vehicle is reversed to the rear of the vehicle loading tray 600, the first swing arm 100 and the second swing arm 200 can still protect the charging gun line from being crushed, further ensuring stable and reliable use, reducing the failure rate, and also reducing the difficulty of vehicle parking and improving the utilization rate of lateral parking spaces.

[0023] A bending space for the charging cable is provided at the connection position of the first swing arm 100 and the second swing arm 200. When the vehicle tray 600 moves left and right, the distance between the charging pile 500 and the vehicle tray 600 changes, while the total length of the charging gun cable outside the charging pile 500 is fixed. When the vehicle tray 600 is closest to the charging pile 500, the charging gun cable is bent in the bending space and close to the outer wall of the bending space. The radius of the bending space is greater than the minimum bending radius of the charging gun cable to avoid damage to the charging gun cable and reduce its service life. When the vehicle tray 600 is farthest from the charging pile 500, the charging gun cable is laid smoothly in the bending space. Therefore, in the actual process, the first swing arm 100 and the second swing arm 200 are used to protect the charging gun cable. By providing a bending space at the connection position between the two, the damage caused by the bending of the charging gun cable is reduced, thereby increasing its service life. The overall structure is simple, fits the ground, is easy to install and has low cost. It can avoid car collisions and also protect against car crushing, thus meeting actual use needs and ensuring safe and reliable use.

[0030] During operation, when the vehicle loading tray 600 moves left and right, the second swing arm 200 drives the first swing arm 100 to move, so that the two are folded or unfolded. During the folding and unfolding process, the charging gun wire is bent in the folding space to ensure the service life of the charging gun wire; the first protective cover 150 and the second protective cover 250 can prevent external debris from corroding the charging gun wire, further improving its service life.

[0031] When the vehicle is parked, if it exceeds the rear end of the vehicle loading tray 600, it will not be scratched or collided with the charging pile gun line protection device, and it can also effectively protect the charging gun line when the vehicle is rolled over.

The second arc segment 221 is coaxially rotatable with the first arc segment 121 through the swing arm pin 130. The second arc segment 221 is located on the outside of the first arc segment 121. When the second arc segment 221 rotates relative to the first arc segment 121, the second arc segment 221 does not interfere with the first transition segment 122, and the first arc segment 121 also does not interfere with the second transition segment 222, thereby ensuring stable and reliable folding.

[0036] In order to improve the strength of the overall structure and ensure that the connection between the first arc segment 121 and the second arc segment 221 is stable and reliable, a universal wheel 400 is preferably provided at the bottom of the second arc segment 221, which can not only support the connection between the two but also avoid friction with the ground, reduce wear and tear, increase service life and reduce noise.

[0037] At the same time, in order to ensure that the first arc segment 121 and the second arc segment 221 are stable and reliable when they rotate relative to each other, it is preferred to set a guide member 301 at the bottom of the first arc segment 121, and open an arc groove 230 matching the guide member 301 at the bottom of the second arc segment 221, and the universal wheel 400 is located on the inner side of the arc groove 230; the guide member 301 can be selected as a bull's eye wheel to reduce the friction generated during rotation and further reduce noise.
