Utility Model Content

[0005] In order to reduce the possibility of the plug of an electric vehicle charger becoming loose during charging, the present application provides an electric vehicle charger with a plug anti-loosening function.

[0006] The electric vehicle charger provided in this application has a plug anti-loosening function and adopts the following technical solution:

The driving member is used to drive the sliding of the several anti-slide blocks. When the plug is inserted into the socket, the sliding plate slides to abut the plug, and the several anti-slide blocks can slide to abut the socket.

[0008] By adopting the above technical solution, when the plug is inserted into the socket, the sliding plate is slid to one side of the plug, and the driving member is used to slide several anti-sliding blocks to abut against the socket, thereby limiting the position of the plug, reducing the possibility of the plug loosening, and reducing the possibility of the plug loosening during the charging process of the electric vehicle charger.

[0009] Preferably, the driving member includes a plurality of connecting rods and a plurality of elastic members, a plurality of the connecting rods correspond to a plurality of anti-sliding blocks and a plurality of elastic members, one end of a plurality of the connecting rods are respectively slidably connected in the sliding plate, a plurality of the anti-sliding blocks are respectively arranged on the corresponding connecting rods, and a plurality of the elastic members always drive the corresponding connecting rods to slide toward one side of the sliding plate.

[0010] By adopting the above technical solution, several anti-sliding blocks are pulled toward the side away from the sliding plate, and are made to abut against the side surfaces around the socket. At this time, several elastic members respectively drive the corresponding connecting rods to slide toward the side of the sliding plate, thereby increasing the friction between the anti-sliding blocks and the side surfaces of the socket, reducing the possibility of the anti-sliding blocks falling off, and thus reducing the possibility of the plug of the electric vehicle charger loosening during charging.

[0015] Preferably, the sliding plate is provided with a through-hole, the power cord passes through the through-hole, and the through-hole can cooperate with the plug. When the sliding plate slides toward the plug to an extreme position, the through-hole cooperates with the plug.

[0019] Preferably, a plurality of protective shells are rotatably connected to the charger body. When the plurality of protective shells are rotated toward opposite sides to abut against each other, the plurality of protective shells and the charger body together form a protective compartment, and the plurality of matching grooves are simultaneously located in the protective compartment.

[0020] By adopting the above technical solution, the anti-detachment component is placed in the protective compartment, which makes it easy to store and protect the anti-detachment component. At the same time, when not in the charging process, the plug and the power cord can also be placed in the protective compartment, which makes it easy to store and protect the plug and the power cord.

[0031] The following is combined with Figure 1-5 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0032] The embodiment of the present application discloses an electric vehicle charger with a plug anti-loosening function.

[0033] Reference Figure 1 , an electric vehicle charger with a plug anti-loosening function of this embodiment includes a charger body 1, a power cord 2 is fixedly connected to the charger body 1, a plug 3 is fixedly connected to the side of the power cord 2 away from the charger body 1, and also includes an anti-dropping component 4, which is used to prevent the plug 3 from falling off, and the anti-dropping component 4 includes a sliding plate 41, four anti-slide blocks 42 and a driving member 43. The sliding plate 41 is slidably connected to the power cord 2 along the central axis of the power cord 2, and the four anti-slide blocks 42 are respectively slidably connected to the sliding plate 41 along a sliding direction perpendicular to the sliding direction of the sliding plate 41. The driving member 43 is used to drive the sliding of the four anti-slide blocks 42 respectively. When the plug 3 is inserted into the socket, the sliding plate 41 slides to abut against the plug 3, and the four anti-slide blocks 42 can slide to abut against the socket.

[0034] Reference Figure 1-Figure 5 When the plug 3 is inserted into the socket, the sliding plate 41 is slid to one side of the plug 3, and the driving member 43 is used to slide the anti-sliding blocks 42 to abut against the socket, thereby limiting the position of the plug 3 and reducing the possibility of the plug 3 loosening during the charging process of the electric vehicle charger.

[0035] Reference Figure 5The driving member 43 includes four connecting rods 431 and four elastic members 432. The four connecting rods 431 correspond to the four anti-sliding blocks 42 and the four elastic members 432. One end of the four connecting rods 431 is respectively slidably connected to the sliding plate 41. The four anti-sliding blocks 42 are respectively rotatably connected to the corresponding connecting rods 431. The four elastic members 432 always drive the corresponding connecting rods 431 to slide toward one side of the sliding plate 41. The four elastic members 432 are four groups of springs 4321. The two ends of the four groups of springs 4321 are respectively fixedly connected to the connecting rods 431 and the sliding plate 41. The four groups of springs 4321 always drive the corresponding connecting rods 431 to slide toward one side of the sliding plate 41. Pull the four anti-slide blocks 42 toward the side away from the sliding plate 41 and make the four anti-slide blocks 42 abut against the side surfaces around the socket. At this time, the elastic members 432 respectively drive the corresponding connecting rods 431 to slide toward the side of the sliding plate 41, thereby increasing the friction between the anti-slide blocks 42 and the side surface of the socket, reducing the possibility of the anti-slide blocks 42 falling off, and thus reducing the possibility of the plug 3 loosening during charging of the electric vehicle charger.

[0036] Reference Figure 1-Figure 5 The four anti-slip blocks 42 are each pivotally connected to the end of the corresponding connecting rod 431 away from the sliding plate 41, along the sliding direction of the corresponding connecting rod 431. Rubber anti-slip portions 421 are fixedly connected to each end of the anti-slip block 42 along its length. These rubber anti-slip portions 421 are positioned at different distances from the rotation axis of the anti-slip block 42. As needed, the four anti-slip blocks 42 can be pivoted individually to contact the socket with the rubber anti-slip portions 421 at different ends, making the anti-slip assembly 4 adaptable to sockets of various sizes.

[0037] Reference Figure 1 and Figure 2 The sliding plate 41 is provided with a through-hole 411 through which the power cord 2 passes. The sliding plate 41 is slidably connected to the power cord 2 through the through-hole 411, and the through-hole 411 can mate with the plug 3. When the sliding plate 41 slides toward the plug 3 to the extreme position, the through-hole 411 mates with the plug 3. When the plug 3 is inserted into the socket, the through-hole 411 mates with the plug 3, and the anti-sliding block 42 abuts against the socket, thereby improving the stability of the plug 3 and further reducing the possibility of the plug 3 loosening during charging of the electric vehicle charger.

[0038] Reference Figure 3 and Figure 4The charger body 1 has four mating slots 11 on the side near the power cord 2 that are mated with the anti-slip block 42. The four anti-slip blocks 42 correspond to the four mating slots 11. When the plug 3 is not plugged into the socket, the four anti-slip blocks 42 can be mated with the corresponding mating slots 11. When the anti-slip blocks 42 are not needed, the sliding plate 41 can be slid toward the side of the charger body 1 and the four anti-slip blocks 42 can be placed in the corresponding mating slots 11, reducing the possibility of damage to the anti-slip assembly 4 when not in use. Two protective shells 12 are rotatably connected to the charger body 1. When the two protective shells 12 are rotated toward opposite sides and abut each other, the two protective shells 12 and the charger body together form a protective compartment 13, and the four mating slots 11 are simultaneously located in the protective compartment 13. By placing the anti-slip assembly 4 in the protective compartment 13, it is convenient to store and protect the anti-slip assembly 4. At the same time, when charging is not in progress, the plug 3 and the power cord 2 can also be placed in the protective compartment 13, conveniently storing and protecting the plug 3 and the power cord 2.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
