[0032] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
[0033] Embodiment 1:
[0034] This embodiment introduces a specific structure of an electric vehicle charging port protection device for an electric vehicle body 1. Figure 1-Figure 8 As shown, it includes a protective plate 5 and a charging port cover 2 arranged on one side of the protective plate 5, and the top of which is hingedly connected to the electric vehicle body 1, the bottom of the protective plate 5 is processed with a storage notch 14 and a mounting groove 13, the interior of the mounting groove 13 is provided with a water-absorbing cotton ring 6, and the interior of both sides of the protective plate 5 is processed with a plurality of heat dissipation grooves 10;
[0035] Among them, the cross-section of the water-absorbing cotton ring 6 is U-shaped, and the installation groove 13 is located on one side of the receiving groove 14, and the two are connected to each other. When the water-absorbing cotton ring 6 is pasted to the installation groove 13, because the coverage area of the installation groove 13 is larger than the coverage area of the receiving groove 14, it can be ensured that the water-absorbing cotton ring 6 is received inside the installation groove 13, and the coverage area of the inner side of the water-absorbing cotton ring 6 is smaller than the coverage area of the receiving groove 14, so that the inner side of the water-absorbing cotton ring 6 can protrude from the inside of the installation groove 13. When the charging gun is plugged into the plug 4, the water-absorbing cotton ring 6 can wrap the outer side of the charging gun. When it rains, the rainwater is blocked by the protective plate 5, and when the rainwater enters the charging socket 12 close to the plug 4 from the protective plate 5 and the charging gun, the water can be absorbed by the water-absorbing cotton ring 6 to form a water seal for blocking;
[0036] At the same time, if Figure 5 As shown, multiple heat dissipation slots 10 are arranged obliquely, and their cross-section is a parallelogram. When exposed to high temperature, the protective plate 5 blocks the sunlight on one side of the plug 4, and the high-temperature air generated in the connection area between the charging gun and the plug 4 is discharged to the outside through the space between the bottom of the protective plate 5 and the inner wall of the bottom of the charging socket 12 and the inside of the multiple heat dissipation slots 10;
[0037] like Figure 3 As shown, a charging socket 12 and a storage cavity 7 are processed inside the body 1 of the electric vehicle, a plug 4 is arranged inside the charging socket 12, and slide grooves 8 are processed on the inner walls on both sides of the storage cavity 7;
[0038] The receiving cavity 7 is located at the top of the charging socket 12 and communicated with the charging socket 12, and the protective plate 5 is retractably connected to the inside of the charging socket 12. When the protective plate 5 is controlled to move from the inside of the charging socket 12 to the inside of the receiving cavity 7, the plug 4 can be completely exposed to the inside of the charging socket 12, so that the corresponding components can be disassembled and repaired without affecting the design of the existing structure of the plug 4.
[0039] Secondly, in order to prevent the protective plate 5 from being placed inside the charging socket 12 under the influence of gravity without external force, affecting its stability during use, such as Figures 3 to 5 As shown, both sides of the top of the protective plate 5 are processed with a sliding cavity 18, and a slider 11 is slidably connected inside the sliding cavity 18. Two first springs 15 are arranged between one end of the slider 11 and the inner wall of one side of the sliding cavity 18. By making the slider 11 extend from the inside of the sliding cavity 18 under the support of the first spring 15 and located inside the sliding groove 8, pressure can be applied to the inner wall of one side of the sliding groove 8 by means of one end of the slider 11, so as to limit the movement of the protective plate 5 inside the storage cavity 7 without external force. When it is necessary to control the protective plate 5 to move from the inside of the charging socket 12 to the inside of the storage cavity 7, it is only necessary to push the protective plate 5 toward the top, so that the two sliders 11 can be slidably connected to the inside of the two sliding grooves 8 respectively.
[0040] At the same time, in order to prevent the first spring 15 from bending when it is stretched and expanded inside the slide groove 8, as shown in FIG. Figure 6 As shown, two positioning rods 16 are processed on the inner wall of one side of the sliding cavity 18, and the two first springs 15 are respectively connected to the outside of the two positioning rods 16 in a sleeve-type manner, and the slider 11 is slidably connected to the outside of the two positioning rods 16, so that the two positioning rods 16 can be used to position the two first springs 15 for movement;
[0041] Furthermore, in order to facilitate the removal of the protective plate 5 from the storage chamber 7, Figure 3 and Figure 4 As shown, a slope 17 is processed at the bottom of one side of the slider 11. By making the width of the slope 17 larger than the thickness of the slide groove 8, when the bottom of the slope 17 is supported at the edge of one side of the bottom of the slide groove 8, the protective plate 5 can be controlled to move toward the bottom, and the edge of the bottom of the slide groove 8 can be pressed by the slope 17, so that the reverse force can be used to make the slider 11 move toward the inside of the slide cavity 18, and finally the first spring 15 is compressed, so that the two sliders 11 are respectively disengaged from the inside of the two slide grooves 8 to eliminate the obstruction.
[0042] By adopting the above technical solution:
[0043] The above design sets a protective plate 5 on one side of the plug 4 on the electric vehicle body 1, and processes a mounting groove 13 and a storage groove 14 at the center of the bottom of the protective plate 5, so that the water-absorbing cotton ring 6 is pasted to the inside of the mounting groove 13, and multiple inclined heat dissipation grooves 10 are processed on both sides of the bottom of the protective plate 5. When the charging gun on the charging pile is plugged into the inside of the plug 4, the inner side of the water-absorbing cotton ring 6 fits with the surface of the charging gun, so that when it rains, rainwater is blocked by the protective plate 5, and the barrier from the protective plate 5 and the charging gun to the charging socket 12 close to the plug 4 is formed by the water-absorbing cotton ring 6 absorbing water to form a water seal;
[0044] At the same time, when encountering high temperature exposure, the protective plate 5 blocks the sunlight on one side of the plug 4, and the high-temperature air generated in the connection area between the charging gun and the plug 4 can be discharged to the outside through the space between the bottom of the protective plate 5 and the inner wall of the bottom of the charging socket 12 and the inside of multiple heat dissipation grooves 10, which is conducive to ensuring a good shading effect.
[0045] Embodiment 2:
[0046] Based on Example 1, this example introduces the specific structure of the charging port cover 2. Figure 1 , Figure 5 , Figure 7 and Figure 8 As shown, a locking structure 3 is provided at the top of one side of the charging port cover 2, and the locking structure 3 includes a sleeve 302, one end of the sleeve 302 is integrally formed with a ball head 301, and a ball groove 9 is processed at the center of the top surface of the protective plate 5;
[0047] Among them, by making the ball head 301 fit and connect inside the ball groove 9, when the charging port cover 2 is controlled to flip down to the bottom and buckle inside the charging socket 12 on the electric vehicle body 1, the ball head 301 on the locking structure 3 can be driven to extend into the ball groove 9 to position the protective plate 5, so as to prevent the protective plate 5 from shaking inside the charging socket 12 due to the bumpy driving of the car, thereby affecting the service life of various components;
[0048] Secondly, in order to make the ball head 301 stably fall into the ball groove 9, the connection gap is eliminated, such as Figure 5 and Figure 7 As shown, the second spring 305 is sleeve-connected inside the sleeve 302, and a support column 303 is provided at one end of the second spring 305. After one end of the support column 303 is connected and fixed to the charging port cover 2, the sleeve 302 can be slidably connected to the outside of the support column 303 when the ball head 301 applies pressure to the surface of the protective plate 5, and the expansion and contraction amount of the second spring 305 can be controlled, and finally the surface of the ball head 301 is completely fitted with the inner wall of the ball groove 9, so that the ball head 301 limits the protective plate 5;
[0049] Furthermore, in order to prevent the sleeve 302 from being separated from the outside of the support column 303, the second spring 305 can be replaced. Figure 8 As shown, a groove 304 is machined inside the sleeve 302, and a limiting rod 306 is internally pinned at one end of the support column 303. When the limiting rod 306 is pinned from the inside of the sleeve 302 to the inside of the support column 303, the limiting rod 306 can be slidably connected to the inside of the groove 304. With the cooperation between the groove 304 and the limiting rod 306, the range of movement of the groove 304 outside the support column 303 is limited.
[0050] By adopting the above technical solution:
[0051] The above design arranges a support column 303 and a groove 304 with a second spring 305 between them on one side of the charging port cover 2, and forms a ball head 301 at one end of the groove 304. When the charging port cover 2 is controlled to flip down to the bottom and buckle inside the charging socket 12 on the electric vehicle body 1, the ball head 301 on the locking structure 3 can be driven to extend into the ball groove 9, and the second spring 305 is used to support between the support column 303 and the groove 304, so that the surface of the ball head 301 is completely in contact with the inner wall of the ball groove 9, so as to position the protective plate 5 and prevent the protective plate 5 from shaking inside the charging socket 12 due to the bumpy driving of the car.
[0052] Specifically, when using the electric vehicle charging port protection device:
[0053] When charging, remove the charging gun from the charging pile and insert it into the inside of the plug 4 through the storage slot 14 at the bottom of the protective plate 5, so that its surface fits the inner wall of the absorbent cotton ring 6, and use the existing anti-dropping means to ensure a stable connection between the charging gun and the plug 4;
[0054] When encountering heavy rain, rainwater enters the interior of the charging socket 12 from the outside of the electric vehicle body 1, and is first blocked by the protective plate 5. Most of the rainwater, while the water that penetrates from the connection area between the charging gun and the protective plate 5 is absorbed by the absorbent cotton ring 6, thereby forming a water seal, ensuring that the protective plate 5 blocks rainwater from entering the connection area between the charging gun and the plug 4.
[0055] When it is sunny and the electric vehicle body 1 is exposed to the sun, the protective plate 5 blocks the sunlight on one side of the plug 4, and the heat generated in the connection area between the charging gun and the plug 4 is discharged to the outside through the space between the bottom of the protective plate 5 and the inner wall of the bottom of the charging socket 12 and the inside of the multiple heat dissipation grooves 10;
[0056] When charging is completed, remove the charging gun from the inside of the plug 4, flip the charging port cover 2 to the bottom and buckle it into the charging socket 12 on the electric car body 1, drive the ball head 301 on the locking structure 3 to extend into the inside of the ball groove 9, so that the ball head 301 drives the ball head 301 to apply pressure to the second spring 305 between the support column 303 and the second spring 305, so that it is compressed, ensuring that the ball head 301 is supported by the second spring 305 and is stably located in the ball groove 9, limiting the movement of the protective plate 5 inside the charging socket 12 and the storage cavity 7, and ensuring the stability of the protective plate 5 during the driving of the car.
[0057] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
