[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] In the embodiments of this invention, please refer to Figures 1 to 10 The waterproof device for the charging pile includes a charging pile housing 1, wherein an installation window is provided on the side wall of the charging pile housing 1, and further includes:

[0058] The heat dissipation plate 2 is located inside the installation window and is connected to the charging pile housing 1 via a hinge. The heat dissipation plate 2 has several sets of heat dissipation holes.

[0059] Drainage channel 3 is provided on the side wall of the charging pile housing 1 and located below the heat dissipation plate 2. The drainage channel 3 is connected to the installation window.

[0060] The fixing plate 4 is connected to the heat dissipation plate 2 on one side. There are two sets of fixing plates 4, which are arranged symmetrically.

[0061] The heat dissipation mechanism 5 is connected to the fixing plate 4. The heat dissipation mechanism 5 is provided with several sets for dissipating heat from the charging pile housing 1.

[0062] Waterproof mechanism 6 is used to prevent external rainwater from entering the interior of the charging pile housing 1. The waterproof mechanism 6 includes:

[0063] The sealing component 61 is connected to the charging pile housing 1 and to the fixing plate 4, and is used to seal the installation window in conjunction with the fixing plate 4;

[0064] The water-absorbing component 62 is connected to the fixing plate 4. The water-absorbing component 62 is located on the side of the sealing component 61 away from the heat dissipation plate 2, and is used to absorb moisture in the air.

[0065] The water-vibrating component 63 is connected to the heat dissipation mechanism 5 and is used to tap the heat dissipation perforated plate 2 to shake off the water droplets remaining on the heat dissipation perforated plate 2.

[0066] In the initial state, the heat inside the charging pile housing 1 is dissipated through the heat dissipation plate 2. When it rains, if the amount of rainwater is small, the sealing component 61 works with the heat dissipation plate 2 to waterproof the area. A small amount of rainwater enters the installation window through the heat dissipation plate 2 and flows downwards along the heat dissipation plate 2. Since the installation window is connected to the drainage channel 3, the small amount of rainwater entering the installation window is directly discharged through the drainage channel 3. The water absorption component 62 absorbs the moisture in the air. When the amount of rainwater is large, the sealing component 61 moves to seal the space between the heat dissipation plate 2 and the charging pile housing 1, preventing rainwater from entering the interior of the charging pile housing 1. At this time, the heat dissipation inside the charging pile housing 1 is slower, and the temperature rises. The heat dissipation mechanism 5 works to dissipate heat from the charging pile housing 1, and the water vibration component 63 works to tap the heat dissipation plate 2, shaking off the rainwater and dust remaining on the heat dissipation plate 2.

[0067] As one embodiment of the present invention, please refer to Figures 3 to 5 , Figures 8 to 10 The heat dissipation mechanism 5 includes:

[0068] Telescopic frame plate 51, the telescopic frame plate 51 is composed of several groups of square frames that are slidably fitted together, the outermost square frame outer wall is connected to the fixing plate 4, and the innermost square frame is closed at the end away from the side wall of the mounting window.

[0069] The telescopic component 52 is connected at one end to the fixed plate 4 and at the other end to the innermost square frame.

[0070] The cooling fan 53 is connected to the outermost side of the telescopic frame plate 51.

[0071] When it rains, after the sealing component 61 seals the space between the charging pile housing 1 and the heat dissipation plate 2, the heat inside the charging pile housing 1 is difficult to dissipate through the heat dissipation holes on the heat dissipation plate 2. The heat inside the charging pile housing 1 rises, and the temperature detection element in the detection controller (not shown in the figure) detects this increase. The control element in the detection controller receives the electrical signal from the temperature detection element and controls the telescopic component 52 to work, causing the telescopic frame plate 51 to move and extend. Simultaneously, the control element controls the cooling fan 53 to work, allowing hot air from inside the charging pile housing 1 to enter the telescopic frame plate 51 and exchange heat with the outside air, thus cooling the inside of the charging pile housing 1. The telescopic frame plate 51 is composed of several sets of square frames that slide together, increasing the contact area between the hot air and the cold air, thus ensuring heat dissipation even on rainy days. The telescopic component 52 can be a cylinder, an electric telescopic rod, etc.

[0072] In this embodiment, the telescopic frame plate 51 is made of a material with good thermal conductivity. The hot airflow inside the charging pile housing 1 enters the telescopic frame plate 51 under the action of the cooling fan 53, and the airflow speed is accelerated. The hot airflow transfers heat to the telescopic frame plate 51, and then exchanges heat with the outside cold airflow, so as to dissipate heat inside the charging pile housing 1. Since the airflow inside the charging pile housing 1 is in a continuous flow state under the action of the cooling fan 53, hot airflow continuously enters the telescopic frame plate 51. After the heat exchange is completed, it flows out from the telescopic frame plate 51 into the charging pile housing 1.

[0073] As one embodiment of the present invention, please refer to Figures 2 to 7 The sealing component 61 includes:

[0074] The sealing piece 611 is rotatably connected to the fixing plate 4. The sealing piece 611 is provided in several groups and is arranged in a straight line along the fixing plate 4 at equal intervals.

[0075] The power component 612 is connected to the charging pile housing 1 and to the sealing plate 611, and is used to drive the sealing plate 611 to rotate;

[0076] The magnetic component 613 is connected to the power component 612 and is used to connect the power components 612 together.

[0077] When the heat dissipation plate 2 is closed, the heat dissipation plate 2 drives the fixing plate 4 and the sealing piece 611 to move, so that the sealing piece 611 is located inside the installation window. The magnetic suction assembly 613 is connected together, so that the power assembly 612 is connected to the sealing piece 611. When it rains, the power assembly 612 drives the sealing piece 611 to rotate, so that several sets of longitudinally arranged sealing pieces 611 rotate to the downward sealing state, sealing the space between the heat dissipation plate 2 and the inside of the charging pile housing 1, preventing rainwater from entering the inside of the charging pile housing 1.

[0078] As one embodiment of the present invention, please refer to Figures 1 to 7 The power assembly 612 includes:

[0079] The water storage frame 6121 is connected to the charging pile housing 1;

[0080] The water outlet pipe 6122 is connected to the bottom of the charging pile housing 1 and communicates with its interior;

[0081] The float plate 6123 is located inside the water storage frame 6121;

[0082] The sliding folding rod 6124 is connected at its top to the float plate 6123. The sliding folding rod 6124 passes through the bottom of the water storage frame 6121 and is slidably connected to it.

[0083] The toothed plate 6125 is slidably connected to the fixed plate 4;

[0084] Gear 6126 is connected to sealing plate 611 and meshes with toothed plate 6125;

[0085] The magnetic attraction component 613 includes:

[0086] Magnetic block 6131 is connected to the bottom end of sliding lever 6124;

[0087] Magnetic block 2 6132 is connected to the top of toothed plate 6125 and has the opposite magnetism to magnetic block 1 6131 on the opposite side.

[0088] When the heat dissipation plate 2 is closed, magnetic block 6131 and magnetic block 6132 are magnetically connected together. When it rains, rainwater enters the water storage frame 6121 and flows out from the outlet pipe 6122. When the rainfall is light, the sealing plate 611 works with the heat dissipation plate 2 to waterproof the water. A small amount of rainwater is discharged through the drainage channel 3. When the rainfall is heavy, the flow rate of the outlet pipe 6122 is less than the inflow rate, and rainwater accumulates in the water storage frame 6121, causing the float plate 6123 to move upward, which drives the sliding folding rod 6124 to move upward. The sliding folding rod 6124 drives the toothed plate 6125 to move, the toothed plate 6125 drives the gear 6126 to rotate, and the gear 6126 drives the sealing plate 611 to rotate, which reduces the gap between several sets of sealing plates 611 to waterproof the water. When the sealing plate 611 rotates to the downward sealing state, it seals the space between the heat dissipation plate 2 and the inside of the charging pile housing 1 to prevent rainwater from entering the inside of the charging pile housing 1.

[0089] In this embodiment, the sealing plate 611 is lightweight, much lighter than the toothed plate 6125. When the sealing plate 611 is in the open state, its light weight prevents it from rotating under its own weight. The buoyancy generated by the float plate 6123 is much greater than the weight of the toothed plate 6125, ensuring that the toothed plate 6125 can move upward synchronously under the buoyancy of the float plate 6123. The magnetic attraction between the first magnetic block 6131 and the second magnetic block 6132 is much greater than the weight of the toothed plate 6125, preventing the toothed plate 6125 from falling under its own weight during longitudinal movement.

[0090] As one embodiment of the present invention, please refer to Figures 2 to 5 The water-absorbing component 62 includes:

[0091] The limiting rod 621 is connected to the side of the fixing plate 4 away from the heat dissipation plate 2, and the limiting rod 621 is provided in several sets;

[0092] The absorbent and dustproof cotton cloth 622 is engaged with the limit lever 621;

[0093] The fixing strip 623 is engaged with the limiting rod 621, and the fixing strip 623 is detachably connected to the fixing plate 4.

[0094] The absorbent and dustproof cotton cloth 622 is engaged with the limiting rod 621, and the absorbent and dustproof cotton cloth 622 abuts against the fixing plate 4. The fixing strip 623 is engaged with the limiting rod 621 to fix the absorbent and dustproof cotton cloth 622, which absorbs moisture from the air.

[0095] In this embodiment, the fixing strip 623 and the fixing plate 4 can be fixed together by bolts.

[0096] As one embodiment of the present invention, please refer to Figure 5 , Figures 8 to 10 The water-vibrating assembly 63 includes:

[0097] Rotate the fan blade 631, pass through the innermost square frame, and rotate to connect with it;

[0098] The fixed bending rod 632 is connected to the rotating fan blade 631;

[0099] The sliding rod 633 is slidably connected to the fixed folding rod 632;

[0100] The vibrating block 634 is connected to one end of the sliding rod 633;

[0101] The elastic element 635 is located inside the fixed folding rod 632, with one end connected to the other end of the sliding rod 633 and the other end connected to the fixed folding rod 632.

[0102] In the initial state, the elastic element 635 does not deform and the vibration block 634 does not contact the heat dissipation plate 2;

[0103] Hot airflow from inside the charging pile housing 1 enters the telescopic frame plate 51, causing the rotating fan blade 631 to rotate. The rotating fan blade 631 drives the fixed bending rod 632 to rotate. Under the action of centrifugal force, the sliding rod 633 moves along the fixed bending rod 632, thereby causing the vibrating block 634 to move. During the rotation, the vibrating block 634 collides with the heat dissipation plate 2. Under the action of the impact force, water and dust adhering to the heat dissipation plate 2 are shaken off, preventing rainwater from entering the charging pile housing 1. The elastic element 635 can be a spring, sheet metal, etc.

[0104] The working principle of this invention is as follows: when the heat dissipation plate 2 is closed, magnetic block 6131 and magnetic block 6132 are magnetically connected together. In the initial state, the sealing piece 611 is in the open state, and the heat inside the charging pile housing 1 is dissipated through the heat dissipation plate 2.

[0105] When it rains, rainwater enters the water storage frame 6121 and flows out from the outlet pipe 6122. When the amount of rainwater is small, the sealing plate 611 remains in its initial state and works with the heat dissipation plate 2 to waterproof. A small amount of rainwater enters the installation window through the heat dissipation plate 2 and is discharged directly through the drainage channel 3. The water-absorbing and dustproof cotton cloth 622 absorbs the moisture in the air.

[0106] When the rainfall is heavy, the water flow rate of the outlet pipe 6122 is less than the inlet water flow rate, and rainwater accumulates in the water storage frame 6121. This causes the float plate 6123 to move upward, which in turn drives the sliding folding rod 6124 to move upward. The sliding folding rod 6124 drives the toothed plate 6125 to move, and the toothed plate 6125 drives the gear 6126 to rotate. The gear 6126 drives the sealing plate 611 to rotate, which reduces the gap between several sets of sealing plates 611 to waterproof the system. When the sealing plate 611 rotates to the downward sealing state, it seals the space between the heat dissipation plate 2 and the inside of the charging pile housing 1 to prevent rainwater from entering the inside of the charging pile housing 1.

[0107] The heat inside the charging pile housing 1 is difficult to dissipate through the heat dissipation holes on the heat dissipation plate 2. As the heat inside the charging pile housing 1 rises, the detection controller detects the rise in the internal temperature of the charging pile housing 1 and controls the telescopic component 52 to work, which drives the telescopic frame plate 51 to move and extend. At the same time, the detection controller controls the cooling fan 53 to work, so that the hot air inside the charging pile housing 1 enters the telescopic frame plate 51 and exchanges heat with the outside air, thereby cooling the inside of the charging pile housing 1. The telescopic frame plate 51 is composed of several sets of square frames that slide together, which increases the contact area between the hot air and the outside cold air, thus ensuring the heat dissipation effect even on rainy days.

[0108] Hot airflow enters the telescopic frame plate 51 inside the charging pile housing 1, causing the rotating fan blade 631 to rotate. The rotating fan blade 631 drives the fixed bending rod 632 to rotate. Under the action of centrifugal force, the vibrating block 634 moves. During the rotation, the vibrating block 634 collides with the heat dissipation plate 2. Under the action of the impact force, the water and dust adhering to the heat dissipation plate 2 are shaken off.

[0109] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
