[0011] By adopting the above technical solution, the installation and disassembly between the anti-fall-off block and the waterproof cover are facilitated.

[0012] Preferably, the waterproof cover is provided with a dovetail groove 2 on an end surface of one end outside the charger body, and the scraper is provided with a T-shaped block 2, and the T-shaped block 2 is plugged into the dovetail groove 2.

[0013] By adopting the above technical solution, the waterproof cover and the scraper can be easily disassembled and connected.

[0014] Preferably, a card slot is provided on the end surface of the charger body, the card slot is located above the mounting slot and is connected to the mounting slot, and the scraper is engaged with the card slot.

[0015] By adopting the above technical solution, the scraper can be conveniently stored when the charger is not in use.

[0016] Preferably, one end of the scraper away from the waterproof cover extends out of the slot, and a pressing slope is provided on the end of the scraper extending out of the slot.

[0017] By adopting the above technical solution, when the charger body is to be used, the waterproof cover can be conveniently pulled out from the charger body by moving the scraper so as to cover the multiple heat dissipation slots.

[0018] Preferably, a magnetic block 1 is provided on the anti-slip block, and a magnetic block 2 is provided in the charger body. The magnetic block 2 is located above a plurality of heat dissipation slots, and the magnetic block 1 and the magnetic block 2 are magnetically coupled with each other.

[0019] By adopting the above technical solution, when the waterproof cover blocks multiple heat sinks, magnetic block one and magnetic block two are attracted to each other to prevent the wind from blowing the waterproof cover back into the charger body, thereby ensuring the waterproof effect of the waterproof cover in blocking multiple heat sinks.

[0020] Preferably, a hemispherical guide block is provided on the bottom surface of the installation groove, and a guide groove is provided along the length direction of the waterproof cover on the side facing the multiple heat dissipation grooves, and the guide block is slidably connected in the guide groove.

[0021] By adopting the above technical solution, the waterproof cover is prevented from being skewed when being pulled out of the charger body or being pushed into the charger body.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The utility model can prevent rainwater from entering the electric vehicle charger through the heat dissipation groove when the electric vehicle charger is in use by providing a waterproof cover;

[0024] 2. The utility model is provided with an anti-falling block to prevent the waterproof cover from falling out of the charger body;

[0025] 3. The present invention prevents the waterproof cover from tilting when being pulled out of the charger body or pushed into the charger body through the cooperation of the guide block and the guide groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is a further detailed description of the present application in conjunction with the accompanying drawings to make the technical solution of the present application easier to understand and grasp.

[0033] Reference Figure 1-Figure 3 A waterproof electric vehicle charger of this embodiment includes a charger body 1, a plurality of heat dissipation grooves 11 are opened on one end surface of the charger body 1, a heat dissipation fan 12 is provided inside the charger body 1, and the heat dissipation fan 12 faces the plurality of heat dissipation grooves 11, and an installation groove 13 is opened on the end surface of the charger body 1, and the installation groove 13 is located above the plurality of heat dissipation grooves 11.

[0034] Reference Figure 1-Figure 3 An arc-shaped waterproof cover 2 is slidably connected in the mounting groove 13, a hemispherical guide block 16 is provided on the bottom surface of the mounting groove 13, and a guide groove 23 is provided along its length direction on one side of the waterproof cover 2 facing the multiple heat dissipation grooves 11, and the guide block 16 is slidably connected in the guide groove 23.

[0035] Reference Figure 2 and Figure 4The end of the waterproof cover 2 away from the charger body 1 is detachably connected to a scraper 3 with a scraping pad 31. The scraper 3 is larger than the mounting slot 13. A dovetail groove 22 is defined along the width of the charger body 1 on the end surface of the waterproof cover 2 located outside the charger body 1. The scraper 3 is also provided with a T-shaped block 32 that plugs into the dovetail groove 22.

[0036] Reference Figure 2 and Figure 3 A slot 14 is formed on the end surface of the charger body 1. The slot 14 is located above and connected to the mounting slot 13. The scraper 3 engages with the slot 14. The end of the scraper 3 that is away from the waterproof cover 2 extends out of the slot 14. A pressing slope 33 is formed on the end of the scraper 3 that extends out of the slot 14.

[0037] Reference Figure 2 and Figure 4 The waterproof cover 2 is provided with an anti-slip block 4 on one end located within the charger body 1. The anti-slip block 4 is larger than the mounting slot 13. A dovetail groove 21 is provided on the end surface of the waterproof cover 2 located within the charger body 1, along the width of the charger body 1. The anti-slip block 4 is provided with a T-shaped block 41, which plugs into the dovetail groove 21. The anti-slip block 4 is provided with a magnetic block 42. A magnetic block 15 is provided within the charger body 1. The magnetic block 15 is located above the plurality of heat dissipation slots 11, and the magnetic block 42 and the magnetic block 15 are magnetically engaged with each other.

[0038] Reference Figure 1 and Figure 2 The anti-slip block 4 prevents the waterproof cover 2 from slipping out of the mounting slot 13, and the scraper 3 prevents the waterproof cover 2 from completely entering the charger body 1.
