Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle charging technology, specifically to an electric vehicle charger with automatic power-off function. Background Art
[0002] Electric bicycles, also known as "electric vehicles," are purely electric vehicles powered by batteries and driven by an electric motor. Electric bicycles require an electric bicycle charger to be charged.
[0003] An electric vehicle charger is a charging device specifically designed for the batteries of electric bicycles. Chargers can be divided into two main categories: those with a power frequency transformer and those without. Chargers for freight tricycles generally use chargers with a power frequency transformer; these are large, heavy, and consume more electricity, but they are reliable and inexpensive. Electric bicycles and electric motorcycles use so-called switching power supply chargers, which are energy-saving and efficient, but prone to failure. Electric vehicle chargers usually have an automatic power-off function.
[0004] Existing electric vehicle chargers with automatic power-off functionality are susceptible to damage from rainwater entering the charger during rainy weather. Therefore, they do not meet current requirements. To address this, we have proposed an electric vehicle charger with automatic power-off functionality. Utility Model Content
[0005] The purpose of this utility model is to provide an electric vehicle charger with automatic power-off capability, in order to solve the problems mentioned in the background art, such as rainwater easily entering the charger when used in rainy weather, leading to charger damage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle charger with automatic power-off capability, comprising a charger body, a fixed bracket fixedly mounted on the outer surface of the charger body, lifting grooves provided on both sides of the bottom end of the fixed bracket, a support rod slidably mounted inside the lifting groove, a support plate fixedly mounted at the bottom end of the support rod, a limit plate fixedly mounted on the outer surface of the support rod, a compression spring movably mounted between the limit plate and the inside of the lifting groove, and the support rod movably passing through the inside of the compression spring.
[0007] Preferably, inclined baffles are fixedly installed on both the front and rear sides of the top of the fixed bracket, and vertical baffles are fixedly installed on the outer ends of the inclined baffles. The inclined baffles and vertical baffles are both made of acrylic sheets.
[0008] Preferably, a plug rod is rotatably mounted on the top of the support rod, a limit buckle is fixedly mounted on the top of the plug rod, and plug holes are provided on both sides of the top of the fixed bracket. The plug rod and the limit buckle extend through the interior of the plug holes to the outside of the top of the fixed bracket.
[0009] Preferably, the charger body has wires on both the front and rear sides, heat dissipation holes on both the front and rear sides, an indicator light on the top surface of the charger body, and an automatic safety cut-off protector inside the charger body. The automatic safety cut-off protector is electrically connected to the wires, and the indicator light is electrically connected to the automatic safety cut-off protector.
[0010] Preferably, the elastic force of the compression spring is greater than the weight of the charger body and the fixed bracket.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the cooperation of the support rod and the support plate, allows the device to be raised by pulling out the support rod when used in rainy weather, thereby creating a height difference between the charger body and the ground, thus preventing rainwater from accumulating on the ground and entering the charger body.
[0013] 2. By combining the inclined baffle and the vertical baffle, this utility model can shield the front and rear sides of the charger body when the device is used in rainy weather, preventing rainwater from entering the charger body. At the same time, the indicator lights can be observed through the transparent inclined baffle and the vertical baffle, so that the charging level can be quickly identified.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Please see Figures 1 to 4This utility model provides an embodiment of an electric vehicle charger with automatic power-off capability, comprising a charger body 1. A fixed bracket 4 is fixedly installed on the outer surface of the charger body 1. Lifting grooves 13 are provided on both sides of the bottom end of the fixed bracket 4. A support rod 10 is slidably installed inside the lifting groove 13. A support plate 9 is fixedly installed at the bottom end of the support rod 10. A limiting plate 11 is fixedly installed on the outer surface of the support rod 10. A compression spring 12 is movably installed between the limiting plate 11 and the inside of the lifting groove 13. The support rod 10 movably passes through the inside of the compression spring 12. Through the cooperation of the support rod 10 and the support plate 9, when the device is used in rainy weather, the support rod 10 can be pulled out to raise the device, thereby creating a height difference between the charger body 1 and the ground, thus preventing rainwater from accumulating on the ground and entering the charger body 1.
[0021] Slanted baffles 5 are fixedly installed on both the front and rear sides of the top of the fixed bracket 4, and vertical baffles 6 are fixedly installed on the outer ends of the slanted baffles 5. Both the slanted baffles 5 and the vertical baffles 6 are made of acrylic sheets. With the cooperation of the slanted baffles 5 and the vertical baffles 6, when the device is used in rainy weather, the front and rear sides of the charger body 1 can be shielded by the slanted baffles 5 and the vertical baffles 6 to prevent rainwater from entering the charger body 1. At the same time, the indicator lights 3 can be observed through the transparent slanted baffles 5 and the vertical baffles 6, so that the charging level can be quickly identified.
[0022] A plug rod 8 is rotatably mounted on the top of the support rod 10. A limit buckle 15 is fixedly mounted on the top of the plug rod 8. Both sides of the top of the fixed bracket 4 are provided with plug holes 7. The plug rod 8 and the limit buckle 15 extend through the interior of the plug hole 7 to the outside of the top of the fixed bracket 4.
[0023] The charger body 1 has wires 2 on both the front and rear sides, and heat dissipation holes 14 on both sides. An indicator light 3 is located on the top surface of the charger body 1. An automatic safety cut-off protector is installed inside the charger body 1, electrically connected to the wires 2. The indicator light 3 is also electrically connected to the automatic safety cut-off protector. The elastic force of the compression spring 12 is greater than the weight of the charger body 1 and the mounting bracket 4.
[0024] When using this automatic power-off electric vehicle charger in rainy weather, first rotate the limit buckle 15. This causes the limit buckle 15 to rotate the plug rod 8 at the top of the support rod 10. When the limit buckle 15 rotates to the direction of the plug hole 7, the limit plate 11 will be reduced by the elastic potential energy of the compression spring 12, causing the support rod 10 to lower the support plate 9. At this time, the limit buckle 15 will retract into the lifting groove 13, maintaining a distance between the charger body 1 and the ground to prevent rainwater from accumulating and seeping into the charger body 1. At the same time, the inclined baffle 5 and the vertical baffle 6 further prevent rainwater from entering. Meanwhile, ventilation is provided through the sides of the inclined baffle 5 and the vertical baffle 6 to maintain good heat dissipation efficiency and prevent the charger body 1 from overheating during charging.
[0025] When used on a sunny day, pressing the support plate 9 will retract the support rod 10 into the lifting groove 13. At this time, the limit buckle 15 and the insertion rod 8 will slide out of the insertion hole 7. Then, rotating the limit buckle 15 will turn it to a position other than the insertion hole 7, thereby limiting the position of the support rod 10 and preventing it from falling, allowing the device to be placed on the ground for use.
[0026] When charging, the automatic safety cut-off protector will automatically cut off the power supply to wire 2 when it detects that the electric vehicle battery is fully charged, thereby achieving automatic power cut-off. The charging status of the electric vehicle battery can also be displayed through indicator light 3, making it convenient for personnel to judge the charging status.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
