DETAILED DESCRIPTION

[0025] The following is a detailed description of an electric vehicle charger with temperature compensation function provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, an embodiment of the utility model provides an electric vehicle charger with a temperature compensation function, comprising: a charger body 1, in which a temperature compensation chip is provided, so that the battery can be properly charged at different ambient temperatures; a vent 6, which is arranged on the left and right sides of the charger body 1, for heat dissipation of the charger body 1; a slide 4, which is arranged on the left and right sides of the charger body 1 and is located at the bottom of the vent 6, for draining accumulated water; a dustproof net 5, which is detachably arranged in the vent 6, for blocking dust and moisture; an inclined block 11, which is arranged in the vent 6 and is located at the bottom of the dustproof net 5, and a placement groove used in conjunction with the dustproof net 5 is provided on the top of the inclined block 11 for sliding off moisture in the humid air.

[0027] By setting the inclined block 11, the dust net 5 can be placed. At the same time, the moisture attached to the surface of the dust net 5 forms water droplets, which slide down to the inclined block 11, and then slide into the chute 4 through the inclined block 11 for discharge, so as to prevent the water droplets attached to the surface of the dust net 5 from penetrating the dust net 5 after long-term accumulation; by setting the vent 6, the position is symmetrical to form natural convection and promote air circulation. At the same time, the position of the vent 6 is located at the top of the charger body 1 to reduce the blockage of the vent 6 due to external factors; the main function of the temperature compensation chip is to automatically adjust the charging parameters according to the change of the ambient temperature to protect the battery from damage. When the temperature is high, the chip will reduce the maximum charging voltage value to avoid overcharging and causing battery damage; when the temperature is low, the chip will increase the maximum charging voltage value to increase the activity of the electrolyte, thereby improving the battery's ability to store electricity.

[0028] like Figure 1 As shown, it also includes: a temperature probe 2 for monitoring the internal and external temperatures of the charger body 1.

[0029] The temperature probe 2 is provided to detect the actual temperature of the external environment when the charger body 1 is working, so as to adjust the charging efficiency of the battery at different temperatures.

[0030] like Figure 2 As shown, grooves are provided on both the left and right sides of the charger body 1 , and the grooves are located at the top of the vent 6 .

[0031] By providing the groove, the connecting bar 8 can be placed to prevent the connecting bar 8 from protruding during use, thereby affecting the normal use and appearance of the charger body 1.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes: a connecting strip 8, which is arranged in the groove, and a plurality of connecting blocks are provided at the bottom of the connecting strip 8, which are connected to the dustproof net 5 and are used for moving the dustproof net 5.

[0033] By setting the connecting strip 8, the bottom of the connecting strip 8 is connected to the dustproof net 5. The connecting strip 8 moves forward and backward under the influence of external force, thereby driving the dustproof net 5 to move synchronously, avoiding the inconvenience of operation due to the small size of the dustproof net 5.

[0034] like Figure 2 and Figure 6 As shown, it also includes: a fixing part 7, which is embedded in the charger body 1 and is symmetrically arranged on the left and right sides for fixing the connecting strip 8; it also includes: a card slot 9, which is arranged on the connecting strip 8 and is symmetrically distributed on the left and right sides for fixing the fixing part 7.

[0035] By providing the fixing portion 7, the connecting strip 8 can be fixed to prevent the connecting strip 8 from falling off during normal use, thereby causing the dustproof net 5 to fall off and affecting its function of blocking dust and moisture.

[0036] like Figure 3 and Figure 6 As shown, the fixing part 7 includes: a placement frame 71, which is embedded in the charger body 1 and is used to provide a placement space; a clamping block 72, which is slidably arranged in the placement frame 71, and the clamping block 72 matches the clamping slot 9 and is used to fix the connecting strip 8; a tension spring 73, which is arranged in the placement frame 71, and one side of the tension spring 73 is connected to the clamping block 72 for resetting the clamping block 72.

[0037] By setting a tension spring 73, one side of the tension spring 73 is connected to the inner cavity of the placement frame 71, and the other side is connected to the clamping block 72, so that when the tension spring 73 is compressed, after the clamping block 72 has no force, the elasticity generated by the tension spring 73 drives the clamping block 72 to reset.

[0038] like Figure 4 As shown, it also includes: an elastic hemisphere 10, which is arranged in the inner cavity of the charger body 1, and the elastic hemisphere 10 is distributed up and down to transfer the pressure on the charger body 1; it also includes: an electric wire 3, which is arranged on the charger body 1 and is used for charging the charger body 1.

[0039] The purpose of providing the elastic hemisphere 10 is to enhance the structural strength of the charger body 1 and prevent the charger body 1 from being deformed or damaged by external factors such as squeezing or hitting. When the charger body 1 is subjected to a force, the upper elastic hemisphere 10 squeezes the lower elastic hemisphere 10, thereby alleviating the pressure on it. At the same time, the elastic hemispheres 10 can be arranged in a staggered manner, which can more effectively disperse and absorb the impact force and reduce the direct impact on the sensitive components inside the charger body 1, thereby protecting the circuit board and components from damage.

[0040] The utility model provides a technical solution in which the charger body 1 works through the electric wire 3, and the charger body 1 is cooled through the vent 6. At the same time, external moisture is blocked on the dustproof net 5, and the water formed by the moisture slides outward through the inclined block 11, and falls to the ground with the cooperation of the slide groove 4; when the dustproof net 5 needs to be cleaned, the block 72 is pulled outward, and the tension spring 73 is deformed during this process, so that the block 72 is separated from the connecting strip 8, and the connecting strip 8 is taken out forward to clean the dustproof net 5. After completion, the connecting strip 8 is pushed backward to reset the block 72.

[0041] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
