Description

Technical Field

[0001] The utility model relates to the technical field of charging guns for new energy vehicles, and in particular to a protective device for charging guns. Background Art

[0002] With the rapid development of the new energy vehicle industry, the safety and convenience of charging facilities have become the focus of users. Although the traditional charging gun design can meet basic charging needs in terms of function, in actual use, especially in the DC fast charging scenario, there are some safety hazards and inconveniences that cannot be ignored.

[0003] First, since the plug and cable of the DC charging gun are relatively heavy, users often need to hold it firmly during operation, which not only increases the labor intensity during use, but also poses safety risks during operation. If the user accidentally lets go at this time, the charging gun may cause its plug to collide with the ground or other hard objects under the gravity of the cable, thereby damaging the structure of the plug and even damaging the charging terminal, affecting charging safety. Secondly, the charging gun may come into contact with the surface of the vehicle during use. If it is not operated properly, it is easy to cause scratches or dents on the vehicle's paint, bringing additional economic burden and psychological pressure to the owner. In addition, when the charging gun is used outdoors, it must also face the test of various environmental factors, such as rain, dust, etc. These factors may cause corrosion or short circuit to the plug of the charging gun, shortening the service life of the charging gun.

[0004] Therefore, the charging guns in the prior art still have a lot of room for improvement in terms of safety, convenience and durability. Based on this background, the utility model proposes a new type of protection device for charging guns, aiming to solve the problems existing in the prior art and provide a safer, more convenient and durable solution for charging new energy vehicles.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1 - Figure 5 In this embodiment, a protective device for a charging gun is provided, which is specifically used to provide additional safety protection and operational convenience, and specifically includes: a shell 1, wherein the shell 1 is symmetrically hinged with two cover bodies 2, and the two cover bodies 2 form a cavity for accommodating the plug when closed, and the two cover bodies 2 are each provided with a pull ring 21, and the two pull rings 21 are connected by a pulling belt 3.

[0024] Specifically, in this embodiment, the shell 1 is integrated on the charging gun, and the charging gun is located in the charging pile before use. At this time, the plug of the charging gun is protected by the charging pile socket, and the two shells 1 are in an open state and are respectively located on both sides of the charging gun. When the charging gun needs to be used, the user first unplugs the charging gun from the charging pile, and needs to hold the lifting belt 3 tightly with his hand to lift the charging gun through the lifting belt 3. Since the cable 8 is located at the lower end of the charging gun, under the action of gravity, the plug of the charging gun faces upward, and the lifting belt 3 pulls the pull ring 21, so that the two covers 2 are closed, and the plug of the charging gun is kept in the cavity between the two covers 2. If the charging gun accidentally falls at this time, the cover 2 can effectively protect the plug of the charging gun. Pull the lifting ring 21 in the opposite direction, drive the pulling ring 21 so that the two covers 2 open to expose the plug, and then insert the plug of the charging gun into the charging port of the vehicle or other energy storage device. Because the charging ports of different devices have different depths, in order to avoid the collision between the cover 2 and the device shell 1, which leads to the inability to insert normally, the hinge position of the shell 1 and the cover 2 should be as far back as possible, away from the plug of the charging gun. When charging is completed, the charging gun can be easily unplugged with the help of the lifting belt 3 through the handle of the charging gun, and the charging gun is lifted again by the lifting belt 3, and finally returned to the charging pile socket. In the whole process of using the above-mentioned charging gun, except for being inserted into the socket of the charging pile and the charging port of the device, the protection of the charging port of the charging gun is achieved by closing the two covers 2. In addition, during the use of the charging gun, the cover 2 can also play a dust and rain protection effect to a certain extent, so that the circuit inside the plug of the charging gun is protected from the invasion of rain and dust, thereby increasing the service life of the charging gun.

[0025] See also Figure 2, the cover 2 is hinged to the housing 1 through a gear shaft 4, the gear shaft 4 is rotatably arranged on the housing 1, a guide rod 5 is arranged in the housing 1, a rack 6 is slidably arranged on the guide rod 5, the left and right sides of the rack 6 are respectively meshed with the gear shaft 4 of one cover 2, a return spring 7 is arranged on the guide rail, one end of the return spring 7 is connected to one end of the rack 6, and the other end of the return spring 7 is fixed on the guide rod 5. In this embodiment, in the absence of external force (when no force is applied to the pull ring 21 or the force applied is to the plug side), the rack 6 slides to one side along the guide rod 5 by the elastic restoring force of the return spring 7, and the rack 6 is meshed with the gear on the gear shaft 4, thereby driving the gear shaft 4 to rotate, and the gear shaft 4 is fixed on the cover 2, and finally the two covers 2 are rotated and closed. When the lifting belt 3 is subjected to traction (away from the plug), a torque is formed through the pull ring 21 and the hinged part, and the torque overcomes the elastic restoring force of the return spring 7, so that the two covers 2 are opened.

[0026] The pull ring 21 is arranged at the edge of the cover body 2 away from the axis of the gear shaft 4. Since the charging gun itself and its cable 8 are heavy, a large force needs to be applied to maintain it when it is held. By designing the pull ring 21 away from the hinge point, the distance between the pull ring 21 and the hinge point is increased. When the lifting belt 3 applies a pulling force at the pull ring 21, the force arm of the pulling force can be effectively increased to form a large torque, so that only a small traction force is required to overcome the restoring force of the reset spring 7 and finally open the two covers 2, which basically has no effect on the use of the charging gun.

[0027] A notch 22 is provided on one side of the cover 2 near the hinge, which is adapted to the charging gun housing 1. The notch 22 is provided on the cover 2 to avoid the housing 1 when it is opened. By enlarging the notch 22, the opening and closing angle of the cover 2 can be increased. In this embodiment, the maximum opening and closing angle of the two covers 2 is 180°. At this time, the plane sides of the two covers 2 are coplanar, and the plug of the charging gun is completely exposed.

[0028] The outer side of the cover body 2 is also provided with an airbag structure 24, and the airbag structure 24 is concentrated at one end close to the plug when the two covers 2 are closed. In this embodiment, by arranging the airbag structure 24 on the outer side of the cover body 2, it can play a buffering role when the charging gun accidentally falls, and reduce the occurrence of desoldering of its internal circuit due to collision. At the same time, since the cable 8 is heavy, some users find it difficult to grasp the charging gun when using it (lack of hand strength, difficulty in dragging). At this time, the falling of the charging gun will easily cause it to collide with foreign objects (it may cause scratches or dents on the paint surface when colliding with the vehicle, and cause pain and injury when colliding with the human body). By setting the airbag structure 24, the corresponding losses can be reduced. Therefore, in order to further reduce damage to vehicles, humans, etc., the outer contour of the cover body 2 should also adopt a full curved surface without edges and corners design, which is a protective effect other than the charging gun.

[0029] See also Figure 5 The contact plane of the cover 2 is embedded with multiple groups of magnets 25, and the magnets 25 arranged at the corresponding positions of the two covers 2 attract each other. The two covers 2 can be closed by the restoring force of the reset spring 7, and magnets 25 that can attract each other (opposite magnetic poles, attracting each other) are arranged on the contact side of the two covers 2, as a supplement to the spring restoring force, so that the contact surface of the two covers 2 is more tightly fitted when closed.

[0030] The housing 1 is symmetrically provided with two buckles 11, and the two covers 2 are both provided with notches 23 that are adapted to be engaged with the buckles 11, and the buckles 11 are made of a flexible material. Since the reset spring 7 is elastic, the two covers 2 may shake, and it is difficult to maintain the closed state. By engaging and adapting the buckles 11 with the notches 23, the covers 2 do not shake in the closed state, and the cavity space of the protective plug is better maintained.

[0031] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
