Technical Field
[0001] The utility model relates to the technical field of chargers, in particular to a charger for electric vehicles. Background Art
[0002] As the use of electric bicycles becomes more and more widespread, in order to ensure the normal use of electric bicycles, it is necessary to charge the electric bicycles in time when they lack power, that is, to use a charger to connect to an external power source to charge the battery in the electric bicycle.
[0003] Existing electric vehicle chargers have connecting wires at both ends for connecting the socket to the battery in the electric vehicle. Since the connecting wires are long, when the charger is stored, the connecting wires are usually wrapped around the charger housing. However, after wrapping, there is no limiting device and the connecting wires usually come loose due to the force. Therefore, a charger for electric vehicles is proposed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.
[0021] Example 1:
[0022] Please refer to Figures 1-4The utility model provides a technical solution: a charger for an electric vehicle, comprising a charger housing 1, a top outer surface of the charger housing 1 is fixedly connected to a fixed block 2 and a limit seat 4, a soft rod 3 is provided on one side of the fixed block 2, and an inserting block 5 is rotatably connected to the other side of the soft rod 3, the left and right inner surfaces of the limit seat 4 are fixedly connected to a first spring 6, the other end of the first spring 6 is fixedly connected to a connecting plate 7, the top outer surface of the connecting plate 7 is fixedly connected to a limit block 8, the rear outer surface of the connecting plate 7 is fixedly connected to a pull plate 10, the inner surface of the inserting block 5 is hollow, and the left and right outer surfaces of the inserting block 5 are provided with limit holes 9. Specifically, when it is necessary to store the connecting wire of the charger, The two pull plates 10 are squeezed toward the middle, and the pull plate 10 drives the connecting plate 7 to deform the first spring 6, so that the limit block 8 is disengaged from the inside of the limit hole 9, and the limit of the plug block 5 is released. By applying force to the soft rod 3, the plug block 5 is disengaged from the inside of the limit seat 4, and the connecting wire is wrapped around the outside of the charger housing 1, and then the plug block 5 is inserted into the inside of the limit seat 4. When the plug block 5 contacts the limit block 8, as the plug block 5 is inserted, the plug block 5 squeezes the limit block 8, causing the first spring 6 to deform until the limit block 8 contacts the limit hole 9. The first spring 6 drives the limit block 8 to insert into the inside of the limit hole 9, and the plug block 5 is limited by the limit block 8, so that the charger connecting wire is pressed and limited by the soft rod 3.
[0023] In this embodiment, two fixing seats 11 are fixedly connected to the outer surfaces of the left and right sides of the charger housing 1. The outer surfaces of the fixing seats 11 are provided with accommodating grooves 12. The inner walls of the fixing seats 11 are located on the upper and lower sides of the accommodating grooves 12 and are provided with cylindrical grooves 13. The interiors of the two cylindrical grooves 13 are fixedly connected with second springs 14, and the other ends of the second springs 14 are fixedly connected with blocks 15. Specifically, after the connecting wires are stored, the plugs at both ends are respectively inserted into the corresponding fixing seats 11. When the connecting wires squeeze the block 15, the second spring 14 is compressed, causing one end of the connecting wire to enter the accommodating groove 12. When the connecting wires are detached from the block 15, the second spring 14 drives the block 15 to reset, so that the block 15 clamps the connecting wire in the accommodating groove 12, thereby clamping the plug inside the fixing seat 11, thereby protecting the plug and preventing it from being wetted by rain.
[0024] In this embodiment, heat dissipation holes 16 are provided on both the front and rear outer surfaces of the charger housing 1. Specifically, the heat dissipation holes 16 are provided to increase the heat dissipation capacity of the charger during use.
[0025] In this embodiment, a sliding groove is provided on the rear outer surface of the limit seat 4, and the two pull plates 10 are both slidably connected to the inside of the sliding groove. Specifically, the sliding groove provides a channel for the movement of the pull plates 10, and the pull plates 10 slide inside the sliding groove when moving.
[0026] In this embodiment, the interior of the limit seat 4 is fixedly connected to a sliding rod, and the two connecting plates 7 are movably mounted on the outer surface of the sliding rod, and the two first springs 6 are mounted on the outer surface of the sliding rod. Specifically, when the connecting plate 7 moves, it slides on the outer surface of the sliding rod, so that the connecting plate 7 moves stably in a straight line, and the first spring 6 is limited by the sliding rod to avoid tilting deformation of the first spring 6.
[0027] In this embodiment, the outer surface of the opposite side of the two limit blocks 8 is an inclined smooth outer surface. Specifically, using the above technical solution, when the insert block 5 is inserted into the interior of the limit seat 4, the insert block 5 squeezes the limit block 8, causing the two limit blocks 8 to move toward each other, causing the first spring 6 to deform.
[0028] In this embodiment, the block 15 has inclined and smooth outer surfaces on both sides. Specifically, by adopting the above technical solution, when the connecting line squeezes the block 15, the second spring 14 can be deformed, so that the block 15 can be retracted under the squeezing force.
[0029] Working principle: When the utility model is in use, when it is necessary to store the connecting wire of the charger, the two pull plates 10 are squeezed toward the middle, and the pull plate 10 drives the connecting plate 7 to deform the first spring 6, so that the limit block 8 is disengaged from the inside of the limit hole 9, and the limit of the plug block 5 is released. By applying force to the soft rod 3, the plug block 5 is disengaged from the inside of the limit seat 4, the connecting wire is wrapped around the outside of the charger shell 1, and then the plug block 5 is inserted into the inside of the limit seat 4. When the plug block 5 contacts the limit block 8, as the plug block 5 is inserted, the plug block 5 squeezes the limit block 8, causing the first spring 6 to deform until the limit block 8 contacts the limit hole 9. The first spring 6 drives the limit block 8 to insert into the inside of the limit hole 9, and the plug block 5 is limited by the limit block 8, so that the charger connecting wire is pressed and limited by the soft rod 3.
[0030] After the connecting wire is stored, the plugs at both ends are respectively inserted into the corresponding fixing seats 11. When the connecting wire squeezes the block 15, the second spring 14 is compressed, so that one end of the connecting wire enters the receiving groove 12. When the connecting wire is separated from the block 15, the second spring 14 drives the block 15 to return, so that the block 15 clamps the connecting wire in the receiving groove 12, thereby clamping the plug inside the fixing seat 11, thereby protecting the plug and preventing it from being wetted by rain.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
