Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle chargers, in particular to a rainproof structure for an electric vehicle charger. Background Technique

[0002] An electric vehicle charger is a charging device specifically configured for the battery of an electric bicycle! Classification of chargers: It can be divided into two categories according to whether there is a power frequency (50 Hz) transformer. Freight tricycle chargers generally use chargers with power frequency transformers, which are large in volume, heavy in weight, and power-consuming, but reliable and inexpensive; electric bicycles and electric motorcycles use so-called switching power supply chargers, which are power-saving and efficient, but prone to damage.

[0003] The prior art discloses a new type of electric vehicle charger (authorized announcement number CN215705721U). This patented technology can freely control the extended length of the power cord within a certain range (controlled by a brake block), saving space to a certain extent and avoiding entanglement between power cords. When the charger is stored, the power cord automatically retracts without the need for winding, making the storage of the charger more convenient and fast, and ensuring that the power cord is not damaged. It can bring an excellent experience to users and at the same time bring economic benefits to the company.

[0004] Although the above prior art can save space and prevent entanglement between power cords by controlling the extended length of the power cord, the existing electric vehicle charger lacks a rainproof structure. Some vehicle owners will use a plastic bag sleeved outside the charger to achieve the rainproof effect, and the sleeving of the plastic bag undoubtedly increases the fire risk, so it is not convenient for people to use. To solve the above problems, we make improvements and propose a rainproof structure for an electric vehicle charger. Content of the Utility Model

[0026] A rainproof mechanism 3 is installed on the top of the upper housing 11. The rainproof mechanism 3 includes a rainproof plate 31, a vertical seat 34, an insertion seat 35 and an insertion sleeve 36. Baffles 33 are fixedly connected to the front side and the back side of the rainproof plate 31. Anti-seepage plates 32 are fixedly connected to both sides of the bottom of the rainproof plate 31. The top of the vertical seat 34 is fixedly connected to the bottom of the rainproof plate 31, the bottom of the vertical seat 34 is fixedly connected to the top of the insertion seat 35, and the inside of the insertion seat 35 is fixedly connected to the surface of the insertion sleeve 36.

[0027] Specifically, heat dissipation holes 16 are provided in the inner cavities of the upper housing 11 and the lower housing 15. The heat dissipation holes 16 are arranged in equal columns inside the upper housing 11 and the lower housing 15. Through the above technical solution, through the arrangement of the heat dissipation holes 16, the effect of discharging the heat inside the upper housing 11 and the lower housing 15 is achieved, avoiding damage to the internal components due to excessive heat inside the upper housing 11 and the lower housing 15. Slots 17 are provided in the inner cavities of the upper connecting seat 12 and the lower connecting seat 13. Guide posts 18 are fixedly connected inside the slots 17. The surface of the guide posts 18 is movably connected to the inside of the insertion sleeve 36. The inside of the slots 17 is movably connected to the surface of the insertion seat 35. Through the above technical solution, through the arrangement of the slots 17, the insertion seat 35 can be smoothly inserted onto the surfaces of the upper connecting seat 12 and the lower connecting seat 13. At the same time, the arrangement of the guide posts 18 enables the insertion sleeve 36 to be sleeved on its surface, further guiding the movement position of the insertion sleeve 36.

[0028] Specifically, the top surface of the rainproof plate 31 is arranged in an inclined structure, and the anti-seepage plate 32 is arranged in a curved structure, and the anti-seepage plate 32 is located on both sides of the lower housing 15. Through the above technical solution, through the inclined arrangement of the top of the rainproof plate 31, the effect of draining water can be achieved when encountering water. At the same time, the anti-seepage plate 32 is arranged in a curved structure to prevent rainwater from seeping back to the inside of the rainproof plate 31.

[0029] Please refer to Figure 1 、 2, 3, and 4, a rainproof structure for an electric vehicle charger. Fixing mechanisms 2 are installed on the front and back sides of both sides of the upper housing 11 and the front and back sides of both sides of the lower housing 15. The fixing mechanism 2 includes a support shaft 22 and a connecting plate 26. The support shaft 22 is fixed to the front and back sides of the insertion seat 35. The surface of the support shaft 22 is movably connected to a fixing plate 21. A clamping groove 24 is formed on one side of the inner cavity of the fixing plate 21. Through the above technical solution, through the arrangement of the support shaft 22, the position of the fixing plate 21 is supported, and then the fixing plate 21 can rotate on the surface of the support shaft 22 to adjust its position.

[0030] Specifically, a limiting plate 23 is fixedly connected to the outside of the support shaft 22. The limiting plate 23 is located outside the fixing plate 21, and the diameter of the limiting plate 23 is larger than that of the support shaft 22.

Through the above technical solution, through the arrangement of the positioning post 25, a groove is formed inside the positioning post 25, and the groove is adapted to the clamping groove 24. Then, the fixing plate 21 can be snapped into the groove inside the positioning post 25 through the clamping groove 24 to position the position of the fixing plate 21.

[0031] The working principle of the present utility model is as follows: First, the upper connecting seat 12 and the lower connecting seat 13 are connected and fixed by bolts. Then, hold the rainproof plate 31 by hand and put the insertion seat 35 on the surfaces of the upper connecting seat 12 and the lower connecting seat 13. At this time, the insertion seat 35 drives the insertion sleeve 36 to insert onto the surface of the guiding column 18, and the rainproof plate 31 is located on the surface of the upper housing 11 until the insertion sleeve 36 inserts to the end of the guiding column 18. Subsequently, rotate the fixing plate 21. The fixing plate 21 rotates on the surface of the support shaft 22, and the limiting plate 23 limits the rotation position of the fixing plate 21. By rotating the fixing plate 21, the clamping groove 24 is driven to snap onto the surface of the positioning post 25, so as to fix the position of the insertion seat 35, and then the rainproof plate 31 can be installed on the surface of the upper housing 11. When rainwater falls on the surface of the rainproof plate 31, it is drained to the outside of the upper housing 11. At this time, the baffle 33 blocks the rainwater in the front and back directions, and when the rainwater falls on the surface of the anti-seepage plate 32, it is drained to the ground. The anti-seepage plate 32 is bent to prevent rainwater from seeping back.
