Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly relates to a multifunctional outdoor charging pile. Background Art

[0002] An outdoor charging pile is a device for supplying power to electric vehicles, usually installed in outdoor public places, such as open and unobstructed places like outdoor parking lots, road shoulders, and beside green belts in communities. It can also be installed in areas such as airports, parks, squares, subway entrances, and commercial streets.

[0003] For existing outdoor multifunctional sunshade charging piles (i.e., there is a sunshade plate at the upper end of the charging pile, and the sunshade plate is usually fixed), to improve the heat dissipation effect of the device, heat dissipation holes are generally provided on the shell of the charging pile. At the same time, to prevent moisture from entering the interior of the shell and condensing into small water droplets that adhere to the electrical equipment inside the charging pile for a long time and affect the service life of the equipment, desiccants (granular) are usually placed at the heat dissipation holes to absorb moisture. However, due to the setting of the sunshade plate, sunlight is blocked on sunny days, weakening the light intensity acting on the charging pile. The moisture evaporation rate in the desiccant after absorbing moisture is slow, easily leading to the humidity inside the shell remaining close to the critical value for a long time, forming a "stuffy steaming" environment and accelerating the deterioration of electrical equipment. Therefore, this application provides a multifunctional outdoor charging pile to meet the requirements. Summary of the Invention

[0004] The purpose of this application is to provide a multifunctional outdoor charging pile to solve the technical problem in the prior art that the sunshade plate will form a light block for the moisture-absorbing desiccant, reducing the moisture evaporation rate, and ultimately accelerating the aging of the electrical equipment inside the charging pile.

[0017] Embodiment: Refer to Figures 1-9 A multifunctional outdoor charging pile shown in the figure, including a charging pile 1.

The opposite ends of the two groups of screw rods 6 are both fixed with first bevel gears 7; Two second bevel gears 9 and a driving gear 10 are respectively installed at both ends of the transmission shaft 8. The second bevel gear 9 is meshed and connected with the two groups of first bevel gears 7.

The gravity touch locking unit locks the automatic shielding unit by relying on the gravity effect after the desiccant absorbs moisture. After the moisture in the desiccant evaporates, the locking of the automatic shielding unit is automatically released; The gravity locking unit includes a loading frame 16 slidably arranged in the inner cavity of the housing through a U-shaped frame 15, a movable rod 22 with a first iron block 25 fixed at one end and a locking column 26 slidably arranged at the other end, and a second iron block 20 movably arranged on the outer wall of the housing; The U-shaped frame 15 is fixedly arranged in the inner cavity of the housing. The lower end of the loading frame 16 is connected to the U-shaped frame 15 through a first linear spring 18. A magnetic isolation block is arranged at the upper end of the loading frame 16, and a first magnetic block 17 is arranged in the groove of the magnetic isolation block. The first magnetic block 17 is arranged opposite to the second iron block 20. A magnetic isolation rod 19 is fixed at the outer end of the second iron block 20, and the magnetic isolation rod 19 slidably penetrates through a limiting plate on the outer wall of the housing. A second magnetic block 21 is arranged in the groove at the upper end of the magnetic isolation rod 19, and a baffle 33 is fixedly sleeved on the magnetic isolation rod 19; An opening is provided on the housing, and a plastic plate 31 is hermetically installed in the inner cavity of the opening, and the plastic plate 31 is located between the first magnet 17 and the second iron block 20; The movable rod 22 is slidably penetrated by a limiting rod 23 fixed to the upper end of the housing. A jacking spring 24 is arranged on the periphery of the movable rod 22, and both ends of the jacking spring 24 are connected to the movable rod 22 and the housing respectively; The upper end of the locking column 26 is provided with a right-angled triangle structure and is located directly below the driving gear 10; The charging frame 16 is in a loop structure and intercepting nets are fixed to both side ends. Desiccant is filled in the accommodation air cavity between the two intercepting nets; It further includes a dust scraping unit to prevent dust from accumulating on the upper end of the second magnet 21 and affecting the magnetic force with the first iron block 25. The dust scraping unit includes a rotating rod 34 rotatably arranged on the magnetic isolation rod 19 and an L-shaped abutting rod 37 fixedly arranged on the outer wall of the first iron block 25. A damping ring is arranged at the connection between the rotating rod 34 and the magnetic isolation rod 19. A cylinder 35 with an arc-shaped groove 38 is fixedly sleeved on the rotating rod 34, and a scraping rod 36 is fixed on the cylinder 35.

[0018] At the beginning, the automatic shielding unit can move automatically. That is, when the temperature is too high, it can automatically unfold to shade the charging pile and extend the aging of the charging pile. When the temperature is low, it returns to its original position; Generally, when the humidity is high, the ambient temperature is generally low. At this time, the automatic shielding unit is in its original position and does not unfold. The desiccant will continuously absorb moisture in this humid environment, thus increasing the overall weight of the desiccant. When it reaches a certain weight, it will automatically lock the automatic shielding unit, making it unable to unfold or contract according to the temperature change. When it is sunny, without the shielding of the automatic shielding unit, more sunlight can directly irradiate on the charging pile, which can accelerate the evaporation of moisture in the desiccant and shorten the overall cycle of the desiccant from "moisture absorption saturation" to "regeneration available". At the same time, in the unshielded state, the temperature inside the housing can rise rapidly, the moisture-carrying capacity of the air is enhanced, water vapor is more easily discharged quickly, the humidity peak value inside the housing is lower, and the risk of condensation is significantly reduced, which is beneficial to reducing the deterioration speed of electrical equipment; Initial state: The baffle 33 on the magnetic isolation rod 19 abuts against the lower end of the limiting plate, and the second magnet 21 makes the movable rod 22 move downward by compressing the jacking spring 24 through magnetic force, and finally makes the upper end of the magnetic isolation rod 19 contact with the lower end of the first iron block 25. At this time, the locking column 26 is located below the toothed plate 12. At the same time, the two movable plates 3 are completely below the top plate 4, that is, in the contracted state; When in a humid environment (usually in a humid environment, due to the change in weight after the desiccant absorbs water, the magnetic isolation rod 19 contacts and separates from the first iron block 25, and the environmental temperature is low, and at this time, the two sets of movable plates 3 are in a contracted state), as the desiccant absorbs more water and becomes heavier, when the weights of the loading frame 16, the magnetic isolation rod 19, and the second iron block 20 are greater than the magnetic force between the second magnet 21 and the first iron block 25, the magnetic isolation rod 19 and the second iron block 20 contact and separate, and its loading frame 16 will quickly move downward a certain distance and then stop. Under the elastic force of the jacking spring 24, the movable rod 22 will drive the locking column 26 to move upward, and the upper end of the locking column 26 will pass through the rectangular through hole 13 and be inserted between the two rectangular locking parts 101 to lock the driving gear 10. When the weather clears, due to the blockage of the locking column 26, its movable plate 3 cannot be unfolded outward for sunshading, and the sunlight can directly irradiate on the housing, which is beneficial to accelerating the evaporation of the moisture in the desiccant. When the desiccant finishes dehumidifying, under the magnetic force of the first magnet 17, the magnetic isolation rod 19 moves upward. When the baffle 33 is about to contact the limiting plate, through the magnetic force, the movable rod 22 will move downward and make the upper end of the magnetic isolation rod 19 contact the lower end of the second iron block 20. At this time, the locking column 26 will move downward and return to its original position, releasing the lock on the driving gear 10. At the same time, through the vaporization and expansion of the internal boiling point liquid filled in the telescopic rod 11, the toothed plate 12 can drive the driving gear 10 to rotate, and through the cooperation of the bevel gears, the two sets of screw rods 6 rotate, and finally the two sets of movable plates 3 move outward and unfold. At night or in a low-temperature environment, the two sets of movable plates 3 return to their original positions; A dust scraping unit is provided. When the second magnet 21 is magnetically fixed to the first iron block 25 (i.e., the initial state), the lower end of the L-shaped contact rod 37 is located in the arc-shaped groove 38, and the scraper 36 is located on one side of the magnetic isolation rod 19; When the second magnet 21 contacts and separates from the first iron block 25, the cylinder 35 moves downward, and the L-shaped contact rod 37 moves upward, thereby causing the scraping rod 36 to rotate clockwise (viewed from above), and finally moving to the other side of the magnetic isolation rod 19; During the process of the magnetic isolation rod 19 moving upward and forming magnetic pull adsorption and fixation with the first iron block 25, the lower end of the L-shaped contact rod 37 moves into the arc-shaped groove 38 and sweeps across the surfaces of the magnetic isolation rod 19 and the second magnet 21 before the magnetic isolation rod 19 contacts the first iron block 25, scraping off the dust on them to prevent the dust from accumulating too thickly and affecting the subsequent magnetic fixation between the second magnet 21 and the first iron block 25.

[0019] It should be noted that: First, the selection of the low-boiling-point liquid can be adaptively selected according to the temperature change of the charging pile installation environment; Second, after the loading frame 16 moves rapidly downward and stops, at this time, the part of the desiccant that absorbs moisture corresponding to the heat dissipation holes 2 moves to the lower part of the heat dissipation holes 2, and the desiccant with less serious moisture absorption (silica gel particles can be selected) will be aligned with the heat dissipation holes, and the subsequent loading frame will continue to move slowly downward; Third, the design of this structure is beneficial to dehumidifying the desiccant in the first time, and the dehumidified desiccant can be reused; Fourth, balls are arranged on the end face where the second iron block 20 contacts the plastic plate 31 to reduce friction; Fifth, when the driving gear 10 is locked, its locking part 101 can contact the plane of the locking column 26 to block the rotation of the driving gear 10; Sixth, waterproof coatings are provided on the outer surfaces of the first iron block 25 and the second iron block 20 to prevent the iron blocks from rusting; Seventh, balls can be arranged at the place where the movable rod 22 is penetrated by the limiting rod 23 to reduce friction, and the limiting rod 23 is arranged close to the first iron block 25, which is beneficial to the downward movement of the movable rod 22 under the action of magnetic force.

[0020] As a preferred implementation manner in this embodiment, a delay locking unit is further provided to prevent the movable plate 3 from not being able to fully retract below the top plate 4 when the locking column 26 is inserted and locked with the driving gear 10, so as to avoid forming light occlusion.

[0021] There are some special situations. When the locking column 26 moves upward, the movable plate 3 may perform a contraction movement (at this time, it is a low-temperature weather). If the locking column 26 is directly inserted and locked with the driving gear 10 at this time, due to the occlusion of part of the movable plate 3, the movable plate 3 can only move after the desiccant is completely dried, which will lead to an extension of the dehumidification time of the desiccant.

[0022] As a preferred implementation manner in this embodiment, as Figure 6 and Figure 8 shown, the delay locking unit includes an L-shaped rod 28 fixed at the upper end to the lower end of the left movable plate 3 and located below the toothed plate 12; A rectangular through hole 29 is provided on the L-shaped rod 28. When the movable plate 3 returns to its original position, the locking column 26 can pass through the rectangular through hole 29 and be inserted and locked with the driving gear 10.

[0023] When the locking column 26 moves upward and the movable plate 3 contracts, the upper end of the locking column 26 will be in pressing contact with the lower end of the L-shaped rod 28. When the movable plate 3 contracts to its original position, the locking column 26 can move upward under the elastic force of the jacking spring 24 and complete the plug-in locking with the driving gear 10, so that the movable plate 3 cannot block the charging pile. When the weather clears, the sunlight can shine on the housing without obstruction, shortening the dehumidification time of the desiccant, which is beneficial to slowing down the deterioration of the electrical equipment inside the housing. After the desiccant finishes dehumidifying, the magnetic force will cause the locking column 26 to move downward, release the locking of the driving gear 10 and return to its original position.

[0024] It should be noted that the outer surface of the L-shaped rod 28 is set as a smooth surface to reduce friction.

[0025] As a preferred implementation manner in this embodiment, an anti-unfolding unit for preventing the movable plate 3 from moving outward and unfolding is further provided. When the locking column 26 moves upward, the movable plate 3 can be locked by the anti-unfolding unit, and at the same time, it does not affect the contraction and reset of the movable plate 3.

[0026] There are some special situations. When the locking column 26 moves upward and the movable plate 3 is unfolding (it is sunny at this time), if the locking column 26 is directly plugged into the driving gear 10 at this time, due to the blocking of part of the movable plate 3, the movable plate 3 can only move after the desiccant is completely dry, which will cause the dehumidification time of the desiccant to be prolonged.

[0027] As a preferred implementation manner in this embodiment, as Figure 8 shown, the anti-unfolding unit includes a positioning groove 30 arranged in rows at the bottom of the L-shaped rod 28 and having a right-angled triangle structure, and a buffer spring 27 with two ends respectively connected to the movable rod 22 and the locking column 26; The positioning groove 30 is located on the right side of the rectangular through hole 29.

[0028] When the locking column 26 moves upward and the movable plate 3 performs an unfolding movement, the upper end of the locking column 26 will be in pressing contact with the lower end of the L-shaped rod 28. As the movable plate 3 continues to unfold outward, and finally, due to the elastic force of the buffer spring 27, the upper end of the right-angled triangle structure of the locking column 26 is inserted into the positioning groove 30. At this time, the outward movement of the movable plate 3 will be blocked, thereby reducing the shading area of the charging pile. When evening comes, the environmental temperature drops, the low-boiling liquid liquefies, and the movable plate 3 performs a contraction movement, which will drive the L-shaped rod 18 to move horizontally, and the inclined surface in the positioning groove 30 is in pressing contact with the upper inclined surface of the locking column 26, and finally the upper end of the locking column 26 moves out of the positioning and enters the next positioning groove 30. As the L-shaped rod 28 continues to move, finally the locking column 26 passes through the rectangular through-hole 13 and is inserted into the driving gear 10, fixing the movable plate 3 in a contracted state and preventing it from blocking the charging pile. When it is sunny, the sunlight can directly shine on the housing, shortening the dehumidification time of the desiccant, which is beneficial to slowing down the deterioration of the electrical equipment inside the housing. After the desiccant finishes dehumidifying, the magnetic force will cause the locking column 26 to move downward, releasing the locking of the driving gear 10 and returning to its original position.

[0029] As a preferred implementation manner in this embodiment, as Figure 2 shown, a shielding cover 32 is provided on the periphery of the housing 1 and near the heat dissipation holes 2, and a waterproof and breathable film layer is provided inside the shielding cover 32.

[0030] The setting of the shielding cover 32 can prevent rainwater from entering the interior of the housing through the heat dissipation holes 2. At the same time, a waterproof and breathable film layer is provided for preliminary waterproofing to avoid large gas water molecules from entering the housing. The desiccant removes the tiny water molecules in the gas, extending the circulation period of the desiccant.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
