[0002] With the popularity of electric vehicles, the construction of charging facilities has become an important part of promoting the development of the electric vehicle industry. However, charging facilities often need to operate under various complex environmental conditions, including rainy days, humidity and other harsh environments. Therefore, waterproof performance has become an important consideration in the design of charging piles.

[0003] In terms of materials, existing waterproof charging piles use materials with high waterproof grades, such as rubber and plastic with excellent waterproof performance, to ensure the waterproof effect of the charging pile shell and internal electrical components.

[0033] A pair of sliders 3 69 slidably arranged on the flip-up cabinet door 4, a pair of driven gears 2 6a rotatably arranged on the two side walls inside the waterproof cabinet 2, a pair of connecting rods 2 6b with one end respectively movably hinged to the two sliders 3 69 and the other end fixedly connected to the two driven gears 2 6a, a pair of transmission gears 2 6c rotatably arranged on the two side walls inside the waterproof cabinet 2 and respectively meshing with the two driven gears 2 6a, a pair of driving gears 2 6d rotatably arranged on the two side walls inside the waterproof cabinet 2 and respectively meshing with the two transmission gears 2 6c, a pair of sliders 4 6e slidably arranged on the top wall inside the waterproof cabinet 2, a pair of connecting pieces 4 6f respectively fixed to one side of the two sliders 4 6e and respectively connected to the two chains 2 39, and a pair of racks 2 6g fixed on the sliders 4 6e and respectively meshing with the two driving gears 2 6d;

[0034] The two driven gears 1 62, the two transmission gears 1 64, the two driving gears 1 65 and the two racks 1 68 are arranged in sequence from high to low, and are symmetrically located on both sides of the waterproof cabinet 2 with the two sliders 1 61, the two sliders 2 66 and the two connecting rods 1 63; the two driven gears 2 6a, the two transmission gears 2 6c, the two driving gears 2 6d and the two racks 2 6g are arranged in sequence from low to high, and are symmetrically located on both sides of the waterproof cabinet 2 with the two sliders 3 69, the two sliders 4 6e and the two connecting rods 2 6b; the connecting piece 3 67 connects the lower half of the chain 1 38, and the connecting piece 4 6f connects the upper half of the chain 2 39; when the driving gear 1 65 is engaged with the rack 1 68 or the driving gear 2 6d is engaged with the rack 2 6g, the charging pile body 1 only moves inside the waterproof cabinet 2.

[0035] like Figure 4As shown, the rotating assembly 33 includes a rotating shaft 331 that rotates vertically inside the waterproof cabinet 2, a three-phase motor 332 that drives the rotating shaft 331 to rotate, a pair of worm 1 333 and worm 2 334 fixed on the rotating shaft 331 and with opposite rotation directions, and a pair of worm gear 1 335 and worm gear 2 336 respectively fixed on the rotating shaft 1 31 and the rotating shaft 2 32. The three-phase motor 332 is fixed to the outer top of the waterproof cabinet 2, and the upper end of the rotating shaft 331 rotates to pass through the top of the waterproof cabinet 2 and is fixedly connected to the output end of the three-phase motor 332. The worm 1 333 and the worm 2 334 are respectively meshed with the worm gear 1 335 and the worm gear 2 336.

[0036] like Figure 4 As shown, an inverted support box body 11 is fixedly provided at the bottom of the charging pile body 1, and the length and width of the support box body 11 are smaller than the length and width of the bottom of the charging pile body 1, and a plurality of parallel and spaced rollers 12 are rotatably arranged in the support box body 11, and the inner bottom wall of the waterproof cabinet body 2 and one side of the lower flip cabinet door 5 are jointly provided with a positioning groove 21 for the roller 12 to roll along the straight line thereof, and a pair of supporting feet 52 are fixedly provided on the downward side of the lower flip cabinet door 5 when it is horizontal, and the bottom of the supporting feet 52 is flush with the bottom of the waterproof cabinet body 2. By adopting the above-mentioned support box body 11 and roller 12, not only can the friction of the charging pile body 1 moving on the bottom of the waterproof cabinet 2 and above the lower flip cabinet door 5 be reduced, so as to cooperate with the moving mechanism 3 to more easily and quickly push and pull the charging pile body 1 in and out of the waterproof cabinet 2, but also, in conjunction with the positioning groove 21, the charging pile body 1 can also move in a straight line, thereby ensuring that the charging pile body 1 can safely and stably enter and exit the waterproof cabinet 2. At the same time, the supporting feet 52 arranged at the bottom of the lower flip cabinet door 5 can also support the suspended part of the lower flip cabinet door 5 to ensure that the charging pile body 1 safely stays on the lower flip cabinet door 5 for charging.

[0037] like Figure 1 , Figure 2As shown, the waterproof cabinet body 2 is vertically fixed with water baffles 22 on both sides of its inlet and outlet, and both sides of the upper flip cabinet door 4 and the lower flip cabinet door 5 overlap with the opposite side of the two water baffles 22. The upper flip cabinet door 4 is fixed with a hinge shaft 41 that rotates through the two water baffles 22 on both sides, and the hinge shaft 41 is located above the inlet and outlet of the waterproof cabinet body 2. The lower flip cabinet door 5 is fixed with a hinge shaft 2 51 that rotates through the two water baffles 22 on both sides, and the hinge shaft 2 51 is located below the inlet and outlet of the waterproof cabinet body 2. One end of the upper flip cabinet door 4 and the lower flip cabinet door 5 is a semicircular contour surface, and the semicircular contour surface frictionally contacts the inlet and outlet side walls of the waterproof cabinet body 2, and the hinge shaft 1 41 and the hinge shaft 2 51 are respectively coaxial with the semicircular contour surface. By adopting the above-mentioned water baffle 22, not only can the infiltration of external accumulated water be further blocked, but also, in combination with the hinge axis 1 41 and the hinge axis 2 51, as well as the relationship of position, the upper flip cabinet door 4 and the lower flip cabinet door 5 can stably and flexibly hinge the waterproof cabinet body 2, and ensure that the upper flip cabinet door 4 and the lower flip cabinet door 5 fully close the entrance and exit of the waterproof cabinet body 2.

[0038] like Figure 2 , Figure 3 As shown, the other end of the upper flip cabinet door 4 and the lower flip cabinet door 5 is an angled surface, a U-shaped support plate 13 is fixedly provided in the middle of the charging pile body 1, and a water retaining strip 14 with an isosceles trapezoidal cross section is fixedly provided on one side of the U-shaped support plate 13. When the upper flip cabinet door 4 and the lower flip cabinet door 5 are vertically flush, the slopes on both sides of the water retaining strip 14 coincide with the angled surfaces of the upper flip cabinet door 4 and the lower flip cabinet door 5. By adopting the above-mentioned U-shaped support plate 13 and isosceles trapezoidal water retaining strip 14, when the upper flip cabinet door 4 and the lower flip cabinet door 5 close the waterproof cabinet body 2, the gap between the ends of the upper flip cabinet door 4 and the lower flip cabinet door 5 can be tightly closed, thereby further preventing the infiltration of accumulated water.

[0039] like Figure 2 , Figure 5 As shown, grooves 53 for sliding blocks 3 69 and 1 61 are respectively provided on one side of the upper cabinet door 4 and the lower cabinet door 5, and guide rods 54 are fixedly arranged in the grooves 53 to movably pass through the slider 1 61 or the slider 3 69. By adopting the above grooves 53 and guide rods 54, not only can the sliding connection between the slider 1 61 and the lower cabinet door 5, the slider 3 69 and the upper cabinet door 4 be realized, but also the sliding stability of the slider 1 61 and the slider 3 69 on the lower cabinet door 5 and the upper cabinet door 4 can be guaranteed.

[0040] like Figure 3 , Figure 6As shown, a pair of T-shaped guide rails 23 are fixedly arranged on the top wall and the bottom wall inside the waterproof cabinet 2, and a T-shaped slide groove 6e1 for sliding connection with the T-shaped guide rails 23 is respectively provided on the slider 2 66 and the slider 4 6e. By adopting the above-mentioned T-shaped guide rails 23 and T-shaped slide groove 6e1, not only can the slider 2 66 and the slider 4 6e be slidably connected to the upper and lower inner walls of the waterproof cabinet 2, but also the sliding stability of the slider 2 66 and the slider 4 6e on the upper and lower inner walls of the waterproof cabinet 2 can be guaranteed.

[0041] like Figure 4 As shown, a U-shaped protective cover 24 covering the rotating shaft 3 331, the worm 1 333, the worm 2 334, the worm wheel 2 336 and the worm 2 334 is fixedly arranged on the inner side wall of the waterproof cabinet 2, and a notch 3b1 for accommodating the U-shaped protective cover 24 is respectively opened in the middle of the upper connecting plate 3a and the lower connecting plate 3b, and the rotating shaft 1 31 and the rotating shaft 2 32 rotate through the side wall of the U-shaped protective cover 24 respectively, and a protective box 25 covering the three-phase motor 332 is fixedly arranged on the top of the waterproof cabinet 2. By adopting the above-mentioned U-shaped protective cover and protective box 25, the safety of each component in the rotating assembly 33 can be effectively protected to avoid water accumulation or other emergencies, which affect the normal operation of the mobile assembly and cause the charging pile body 1 to be unable to smoothly enter the waterproof cabinet 2 for protection.

[0042] The working principle of this embodiment:

[0043] When the charging pile needs to be protected, first, the three-phase motor 332 drives the rotating shaft 331 to rotate, so that the worm 1 333 and the worm 2 334 on the rotating shaft 331 respectively mesh with the worm gear 1 335 and the worm gear 2 336 to rotate. Since the worm 1 333 and the worm gear 2 334 rotate in opposite directions, the worm gear 1 335 and the worm gear 2 336 will respectively drive the rotating shaft 1 31 and the rotating shaft 2 32 to rotate in opposite directions; then the sprocket on the rotating shaft 1 31 The sprocket 35 on the first 34 and the second rotating shaft 32 will respectively drive the chain 38 and the chain 39 to move. Since the upper connecting plate 3a on the back of the charging pile is connected to the lower half of the chain 39 through the connecting piece 3d, and the lower connecting plate 3b is connected to the upper half of the chain 38 through the connecting piece 3c, the upper connecting plate 3a and the lower connecting plate 3b will simultaneously pull the charging pile body 1 and move toward the inside of the waterproof cabinet 2 under the drive of the sprocket 1 and the second chain 39;

[0044] Then, after the charging pile body 1 has completely entered the waterproof cabinet 2, the above-mentioned chain 1 38 and chain 2 39 will continue to pull the charging pile body 1 to move slowly toward the deep inside of the waterproof cabinet 2. At the same time, the slider 1 61 connected to the lower half of the chain 1 38 through the connecting piece 3 67 and the slider 3 69 connected to the upper half of the chain 2 39 through the connecting piece 4 6f will respectively drive the rack 1 68 and rack 2 6g on their upper parts to respectively mesh with the driving gear 1 65 and the driving gear 2 6d to rotate. Since the driving gear 1 65, the transmission gear 1 64 and the driven gear 1 62 are meshed in sequence from bottom to top, and the driving gear 2 6d, the transmission gear 2 6c and the driven gear 2 6a are meshed from top to bottom, the driving gear 2 6d, the transmission gear 2 6c and the driven gear 2 6a are meshed in sequence from top to bottom. The driven gear 1 62 and the driven gear 2 6a will respectively rotate with the driving gear 1 65 and the driving gear 2 6d, and respectively drive the connecting rod 1 63 and the connecting rod 2 6b to flip around with their centers. Moreover, because the slider 2 66 and the slider 4 6e, which slide on the upper flip cabinet door 4 and the lower flip cabinet door 5 respectively, are respectively movably hinged with the ends of the connecting rod 1 63 and the connecting rod 2 6b away from their flipping centers, when the connecting rod 1 63 and the connecting rod 2 6b flip, the slider 2 66 and the slider 4 6e will not only slide along the upper flip cabinet door 4 and the lower flip cabinet door 5 respectively, but also drive the upper flip cabinet door 4 and the lower flip cabinet door 5 to flip in the direction of closing the inlet and outlet of the waterproof cabinet body 2 while sliding.

[0045] Finally, after the upper and lower doors 4, 5 completely close the entrance and exit of the waterproof cabinet 2, the three-phase motor 332 stops working, and the charging pile body 1 stops moving. Because the transmission of the worm gear and the worm has a self-locking function, the upper and lower doors 4, 5 will firmly maintain a close fit with the entrance and exit of the waterproof cabinet 2. In this way, the charging pile body 1 is completely protected inside the waterproof cabinet 2, so as to safely face various emergencies.
