Description

Technical Field

[0001] This utility model relates to the technical field of charging pile bases, specifically a waterproof base structure for an electric vehicle charging pile cabinet. Background Technology

[0002] The charging pile cabinet provides physical protection for the core electrical components of the charging pile, such as charging modules, controllers, power switches, and metering devices, so as to protect them from the influence of external environmental factors, ensure the normal operation of the equipment, and extend its service life.

[0003] In existing technologies, charging pile cabinets are generally placed in various areas. In urban core areas where land resources are scarce, charging pile cabinets need to be compactly laid out so that they can be reasonably installed and arranged in a limited space to meet high-density charging needs.

[0004] However, in areas where charging pile cabinets are placed, if the surrounding drainage channels are not smooth enough, rainwater cannot be effectively and quickly drained during heavy rain. As a result, the water level will rise around the charging pile cabinet. The rising water level may soak parts such as the bottom wiring of the charging pile, leading to a decrease in insulation performance and a risk of leakage accidents. To address this, we propose a waterproof base structure for electric vehicle charging pile cabinets. Utility Model Content

[0005] One of the technical problems this application aims to solve is to reduce the chance of water coming into contact with the charging pile cabinet by designing a height adjustment mechanism on the base of the charging pile cabinet.

[0006] To address the aforementioned technical problems, this application provides a waterproof immersion base structure for an electric vehicle charging station cabinet, comprising: an adjustment mechanism, a guide mechanism on the inner wall of the adjustment mechanism, a base support, an inner rod on the inner wall of the base support, a sliding connection between the inner wall of the base support and one end of the inner rod, a movable arm on the inner wall of the inner rod, a rotatable connection between the inner wall of the inner rod and the bottom end of the movable arm, a base body on the top of the movable arm, a rotatable connection between the top of the movable arm and the bottom side of the base body, a connecting rod on the inner wall of the base body, a sliding connection between the inner wall of the base body and the outer side of the connecting rod, a steel wire rope on the outer side of the connecting rod, contact between the outer side of the connecting rod and the outer side of the steel wire rope, a fixed connection between one end of the steel wire rope and the top side of the base body, and a counterweight on the other end of the steel wire rope, the other end of the steel wire rope being fixedly connected to the top side of one end of the counterweight.

[0007] In some embodiments, the guiding mechanism includes a guide rod, the inner wall of which is provided with a roller, the inner wall of which is rotatably connected to the center of the roller, the outer side of which is perpendicularly rotatably in contact with the inner wall of the counterweight, and the bottom end of the guide rod is fixedly connected to the inner side of the base.

[0008] In some embodiments, one end of the counterweight is slidably connected to one side of the connecting rod, and the bottom end of the connecting rod is fixedly connected to the top side of the base.

[0009] In some embodiments, a protective shell is provided on the top side of the base, the top side of the base is fixedly connected to the bottom end of the protective shell, and the inner side of the protective shell is slidably in contact with the outer side of the base body.

[0010] In some embodiments, a mother tube is provided on the bottom side of the base body, and the bottom side of the base body is fixedly connected to the top end of the mother tube. A daughter tube is provided on the outside of the mother tube, and the outside of the mother tube is vertically slidably connected to the inside of the daughter tube. The bottom end of the daughter tube is fixedly connected to the top side of the base support.

[0011] In some embodiments, a crossbar is provided on one side of the sub-tube, and one side of the sub-tube is fixedly connected to one end of the crossbar. A lead screw is provided on the inner wall of the crossbar, and the inner wall of the crossbar is rotatably connected to the outer side of the lead screw. The outer side of the lead screw is threadedly connected to the inner wall of the middle end of the inner rod.

[0012] In some embodiments, a motor is provided at one end of the lead screw, and the one end of the lead screw is fixedly connected to the output end of the motor. A sleeve is provided on the outside of the motor, and the outside of the motor is fixedly connected to the inside of the sleeve.

[0013] In some embodiments, one end of the sleeve is fixedly connected to one side of the protective shell.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. Starting the motor causes the lead screw to rotate. The lead screw is connected to an inner rod on its outer side. There are two inner rods, and the lead screw is a double-threaded lead screw. Naturally, the two inner rods begin to move in different directions. Since the inner rods are rotatably connected to the bottom of the movable arm, the tilt angle of the movable arm will increase. The maximum angle supplied by the lead screw to the movable arm is 90 degrees. During this process, the base body will be raised from its original height to prevent water from contacting the base body as much as possible. Therefore, this method can automatically raise the height of the base body according to the actual rise in water level, ensuring that the charging pile cabinet is always at a relatively safe height.

[0016] 2. A connecting rod is installed on the inner wall of the base body, and a steel wire rope is installed in the connecting rod. One end of the steel wire rope is fixedly connected to the top side of the base body, and the other end is equipped with a counterweight. The counterweight is located below the base body. In this way, when the base body moves upward, the steel wire rope will move downward under the action of the counterweight. The counterweight moves in the opposite direction below, and the resulting counterforce can effectively counteract the instability caused by the upward shift of the center of gravity.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-6This utility model provides a technical solution: a waterproof base structure for an electric vehicle charging pile cabinet, comprising: an adjustment mechanism 1, a guide mechanism 2 provided on the inner wall of the adjustment mechanism 1, the adjustment mechanism 1 including a base 11, an inner rod 12 provided on the inner wall of the base 11, the inner wall of the base 11 being slidably connected to one end of the inner rod 12, a movable arm 13 provided on the inner wall of the inner rod 12, the inner wall of the inner rod 12 being rotatably connected to the bottom end of the movable arm 13, a base body 14 provided on the top end of the movable arm 13, and the top end of the movable arm 13 being rotatably connected to the bottom side of the base body 14. The base body 14 has a connecting rod 19 on its inner wall. The inner wall of the base body 14 is slidably connected to the outer side of the connecting rod 19. A steel wire rope 110 is attached to the outer side of the connecting rod 19, and the outer side of the connecting rod 19 contacts the outer side of the steel wire rope 110. One end of the steel wire rope 110 is fixedly connected to the top side of the base body 14, and the other end of the steel wire rope 110 is attached to a counterweight 111. The other end of the steel wire rope 110 is fixedly connected to the top side of one end of the counterweight 111, and one end of the counterweight 111 is slidably connected to one side of the connecting rod 19. The bottom end of 9 is fixedly connected to the top side of the base 11. A protective shell 112 is provided on the top side of the base 11. The top side of the base 11 is fixedly connected to the bottom end of the protective shell 112. The inner side of the protective shell 112 is slidably in contact with the outer side of the base body 14. A mother tube 18 is provided on the bottom side of the base body 14. The bottom side of the base body 14 is fixedly connected to the top end of the mother tube 18. A daughter tube 17 is provided on the outer side of the mother tube 18. The outer side of the mother tube 18 is vertically slidably connected to the inside of the daughter tube 17. The bottom end of the daughter tube 17 is fixedly connected to the top side of the base 11. A side of the daughter tube 17 is provided with... One side of the crossbar 16 and the sub-tube 17 are fixedly connected to one end of the crossbar 16. A lead screw 15 is provided on the inner wall of the crossbar 16. The inner wall of the crossbar 16 and the outer side of the lead screw 15 are rotatably connected through it. The outer side of the lead screw 15 is threadedly connected to the inner wall of the middle end of the inner rod 12. A motor 114 is provided on one end of the lead screw 15. One end of the lead screw 15 is fixedly connected to the output end of the motor 114. A sleeve 113 is provided on the outer side of the motor 114. The outer side of the motor 114 is fixedly connected to the inside of the sleeve 113. One end of the sleeve 113 is fixedly connected to one side of the protective shell 112.

[0027] In use, the waterproof base body 14 of this type of electric vehicle charging pile cabinet operates as follows: First, a base support 11 is designed, with sub-tubes 17 installed at each of the four corners. A main tube 18 is vertically slidably connected to each sub-tube 17. The top of the main tube 18 is fixedly connected to the bottom side of the base body 14. Then, the base body 14 is mounted on the main tube 18, creating a certain distance from the ground. If the surrounding water cannot be drained and gradually increases, a movable arm 13 is connected to the bottom side of the base body 14. When not driven, the movable arm 13 is angled at a 40-degree angle. By starting the motor 114, the lead screw 15 rotates, and the outer side of the lead screw 15 is connected to... There are two inner rods 12, and the lead screw 15 is a double-threaded lead screw 15. Naturally, the two inner rods 12 start to move in different directions. Since the inner rods 12 are rotatably connected to the bottom of the movable arm 13, the tilt angle of the movable arm 13 will increase. The maximum angle of the movable arm 13 directly supplied by the lead screw 15 is ninety degrees. During this process, the base body 14 will be raised on the original basis to prevent water from contacting the base body 14 as much as possible. Therefore, this method can automatically raise the height of the base body 14 according to the actual rise of the water level, ensuring that the charging pile cabinet is always at a relatively safe height, effectively avoiding the problem of the charging pile being affected by excessive water accumulation.

[0028] During the process of the base body 14 moving upward, the mother tube 18 will slide vertically within the daughter tube 17, ensuring that the entire structure can always maintain a vertical state during the process of the base body 14 rising or falling, which greatly avoids the instability of the center of gravity that may be caused by tilting. This means that even in a waterlogged environment with rapid water flow and complex ground conditions, the charging pile cabinet can remain upright as the height of the base body 14 is adjusted.

[0029] Secondly, as the base body 14 raises the height of the charging pile, the position of the center of gravity will naturally change. Therefore, a connecting rod 19 is provided on the inner wall of the base body 14, and a steel wire rope 110 is provided in the connecting rod 19. One end of the steel wire rope 110 is fixedly connected to the top side of the base body 14, and the other end is provided with a counterweight 111. The counterweight 111 is located below the base body 14. In this way, when the base body 14 moves upward, the steel wire rope 110 will move downward under the action of the counterweight 111. The counterweight 111 moves in the opposite direction below, and the reverse force it generates can effectively counteract the instability caused by the upward shift of the center of gravity, such as the tilting force caused by strong winds, uneven ground, or the lateral force generated by water flow. The counterweight 111 can help the base body 14 and the charging pile maintain a stable upright state.

[0030] Example 2: Please refer to Figures 2-5The guide mechanism 2 includes a guide rod 21, and a roller 22 is provided on the inner wall of the guide rod 21. The inner wall of the guide rod 21 is rotatably connected to the center of the roller 22. The outer side of the roller 22 is perpendicularly rotatably contacted with the inner wall of the counterweight 111. The bottom end of the guide rod 21 is fixedly connected to the inner side of the base 11.

[0031] A guide rod 21 is installed on the inner side of the base 11, and a roller 22 is designed in the guide rod 21. The guide rod 21 is located inside the counterweight 111. In this way, during the downward movement of the counterweight 111, the counterweight 111 slides along the roller 22 on the guide rod 21, which greatly reduces the resistance and unevenness of friction during the movement. This allows the counterweight 111 to always maintain a vertical and stable downward trajectory. The structure of the guide rod 21 and the roller 22 can effectively buffer these external forces, ensuring that the counterweight 111 moves down stably, thereby ensuring the stability of the entire base body 14 and the charging pile during the height adjustment process, and avoiding the center of gravity imbalance caused by the shaking of the counterweight 111.

[0032] Please see Figures 1-5 The motor 114 is started, causing the lead screw 15 to rotate. The lead screw 15 is connected to two inner rods 12, and the lead screw 15 is a double-threaded lead screw. Naturally, the two inner rods 12 begin to move in different directions. Since the inner rods 12 are rotatably connected to the bottom of the movable arm 13, the tilt angle of the movable arm 13 increases. The maximum angle supplied by the lead screw 15 to the movable arm 13 is ninety degrees. During this process, the base body 14 is raised to a higher position, preventing water from contacting the base body 14 as much as possible. A connecting rod 19 is installed on the inner wall of the base body 14, and the connecting rod 19 contains a steel wire rope 110. One end of the wire rope 110 is fixedly connected to the top side of the base body 14, and the other end is provided with a counterweight 111. The counterweight 111 is located below the base body 14. When the base body 14 moves upward, the wire rope 110 will move downward under the action of the counterweight 111. The counterweight 111 moves in the opposite direction below, and the reverse force it generates can effectively counteract the instability caused by the upward movement of the center of gravity. During the process of the base body 14 moving upward, the main tube 18 will slide vertically in the sub-tube 17, ensuring that the entire structure can always maintain a vertical state during the rise or fall of the base body 14, which greatly avoids the instability of the center of gravity that may be caused by tilting.

[0033] During the downward movement of the counterweight 111, it slides vertically along the roller 22 on the guide rod 21, which greatly reduces the resistance and unevenness of friction during the movement. This allows the counterweight 111 to maintain a vertical and stable downward trajectory. The structure of the guide rod 21 and roller 22 can effectively buffer these external forces and ensure that the counterweight 111 moves down stably.
