Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a self-sealing concealed charging pile. Background Technology

[0002] As an important supporting equipment for electric vehicles, the charging pile of new energy electric vehicles functions similarly to the gas pump in a traditional gas station. It is mainly used to provide electric energy to electric vehicles. The charging pile is usually installed in a fixed manner and is mainly distributed in commercial buildings, such as public buildings, large shopping malls, public parking lots, as well as underground parking lots in residential areas or dedicated electric vehicle charging stations. Its design has broad compatibility and can provide charging services for different models of electric vehicles. From the perspective of electrical connection, the input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a standardized charging plug to achieve reliable connection with electric vehicles and power transmission.

[0003] However, regarding the operating environment, most outdoor charging stations are currently installed directly on the ground. This installation method exposes the charging stations to the natural environment for extended periods, subjecting them to continuous erosion from wind, sun, and other climatic factors. This exposed installation not only accelerates the aging process of the charging station's casing and internal components but may also affect its long-term stable operation, thereby shortening its lifespan. Existing solutions include designing the charging stations as liftable models and incorporating protective shielding structures, but these methods still have certain shortcomings.

[0004] First, additional sensors or control programs are needed to control the shielding structure to provide protection for the charging pile, which increases the equipment cost.

[0005] Secondly, the synchronous closing of the shielding structure is prone to creating gaps, which cannot provide good sealing and affect the environmental adaptability of the equipment;

[0006] Therefore, it is necessary to design a self-sealing, concealed charging station. Utility Model Content

[0007] The purpose of this invention is to provide a self-sealing concealed charging pile to solve the problems of existing solutions, such as designing the charging pile as a lift-up type and designing a shielding structure for protection, which requires additional sensors or control programs to control the shielding structure to provide protection for the charging pile, increasing equipment costs, and the synchronous closing of the shielding structure is prone to creating gaps, failing to provide good sealing performance, and affecting the environmental adaptability of the equipment.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a self-sealing concealed charging pile, including an installation box with an opening at the top, a vertically sliding lifting platform inside the box, a power mechanism for driving the lifting platform to rise and fall, and a charging pile body fixedly installed on the lifting platform. The top of the installation box is symmetrically provided with two shielding components, each shielding component including: a vertical plate, a rotating shaft, a baffle and a winding roller, which provide protection for the charging pile body when it is not in use.

[0009] The upright plate is mounted on the mounting box, the rotating shaft is rotatably connected to the upright plate, the baffle is fixedly connected to the rotating shaft, and a winding roller is fixedly connected to the rotating shaft through the upright plate. The rotation of the winding roller can synchronously drive the rotating shaft and the baffle to rotate.

[0010] The rotating shaft is provided with a torsion spring that provides rotational elasticity. When the charging pile body and the lifting platform rise, the torsion spring releases the elasticity to make the rotating shaft rotate, thereby opening the baffle.

[0011] The bottom of the lifting platform is equipped with a linkage control mechanism. The winding roller is wound with a steel wire rope. The steel wire rope passes downward through the mounting box, the lifting platform and the linkage control mechanism and is connected to a control board. When the control board descends, it can drive the winding roller to rotate with the help of the steel wire rope.

[0012] When the lifting platform descends, the linkage control mechanism presses the control plate to pull the wire rope, driving the baffle to rotate and close the opening; when the lifting platform rises, the torsion spring drives the baffle to rotate and open the opening.

[0013] As a further technical solution of this utility model, a water-blocking frame is provided at the opening on the top of the installation box, and the water-blocking frame provides a certain height to prevent water from flowing directly into the box;

[0014] The baffle is provided with a U-shaped frame at its edge. A first U-shaped rubber sheet is provided inside the U-shaped frame to seal with the water-blocking frame. A second U-shaped rubber sheet is provided outside the U-shaped frame to seal with the top surface of the mounting box.

[0015] As a further technical solution of this utility model, the linkage control mechanism includes: an installation tube, a sliding tube, a first push ring, a compression spring, a fixed tube, and a second push ring;

[0016] Both the mounting pipe and the fixing pipe are fixedly connected to the lifting platform, and the mounting pipe and the fixing pipe are located above the control panel.

[0017] The sliding tube and the mounting tube are in sliding fit. A first push ring is installed at the lower end of the sliding tube, and a compression spring is sleeved between the sliding tube and the mounting tube.

[0018] A second push ring is installed at the lower end of the fixed tube;

[0019] When the lifting platform descends, the first push ring contacts the control board to drive a baffle to close, and after the compression spring is compressed, the second push ring contacts the control board to drive another baffle to close.

[0020] As a further technical solution of this utility model, a slot is provided at the free end of the baffle corresponding to the first push ring, and a rubber strip is embedded in the slot;

[0021] The free end of the baffle corresponding to the second push ring is provided with a retaining strip. When the two baffles are closed, the retaining strip is embedded in the retaining groove and fits tightly with the rubber strip to form a seal.

[0022] As a further technical solution of this utility model, the power mechanism includes: a threaded rod, a connecting block, a worm gear, a worm, a drive motor, a sprocket, and a chain;

[0023] The threaded rods are two sets of vertically rotatably mounted in the mounting box, the sprockets are fixedly connected to the two threaded rods, and the chain is wound around the sprockets;

[0024] The worm gear is fixedly connected to the lower end of the threaded rod;

[0025] The worm gear is rotatably mounted inside the mounting box and meshes with the worm wheel;

[0026] The drive motor is installed inside the mounting box, and the drive motor drives the worm gear;

[0027] The connecting block is fixedly connected to the lifting platform and is screwed onto the threaded rod.

[0028] As a further technical solution of this utility model, the inner wall of the mounting box is provided with a first sliding groove, and the control plate slides in cooperation with the first sliding groove.

[0029] As a further technical solution of this utility model, a column is provided at the bottom of the installation box, and a rubber block is installed at the top of the column;

[0030] The inner wall of the mounting box is provided with a second sliding groove, and a sliding block is fixedly connected to the lifting platform. The sliding block slides in cooperation with the second sliding groove.

[0031] As a further technical solution of this utility model, a rain cover is provided on the outside of the winding roller to provide protection for the winding roller.

[0032] The self-sealing concealed charging station provided by this utility model has the following advantages:

[0033] The motor starts the engine and drives the double threaded rod to rotate synchronously through the worm gear, worm wheel, sprocket and chain. The threaded rod drives the connecting block to raise the lifting platform. The lifting platform is separated from the control board. The torsion spring releases its elastic force and drives the rotating shaft to reverse. The baffle rotates away from the opening and opens. The lifting platform is raised to the highest position and the charging pile extends out from the opening for use.

[0034] When the lifting platform descends, the first push ring at the bottom of the mounting tube contacts the control plate first, pulls the corresponding steel wire rope, and drives the first baffle to close. This baffle has a slot. The sliding tube moves upward inside the mounting tube, and the compression spring stores energy. The lifting platform continues to descend, and the compression spring is fully compressed. The second push ring at the bottom of the fixed tube contacts the control plate, pulls the steel wire rope, and drives the second baffle to close. This baffle has a locking strip, which is embedded in the slot to complete the baffle interlocking seal.

[0035] It can open the cover when the charging pile is raised and seal it when it is lowered, without the need for additional sensors or control programs. This reduces costs while providing protection for the charging pile. At the same time, by closing the baffle in stages, it avoids the problem of gaps that can easily occur when closing synchronously and ensures good sealing performance, significantly improving environmental adaptability.

[0053] Please see the appendix Figure 1 - Appendix Figure 8This utility model provides an embodiment of a self-sealing concealed charging pile, comprising a mounting box 10 with an opening 11 at the top, a vertically sliding lifting platform 20 inside the box, a power mechanism 3 for driving the lifting platform 20 to rise and fall, and a charging pile body 21 fixedly mounted on the lifting platform 20. Two shielding components 40 are symmetrically arranged at the top of the mounting box 10. Each shielding component 40 includes a vertical plate 41, a rotating shaft 42, a baffle 43, and a winding roller 44. The shielding components 40 provide protection for the charging pile body 21 when it is not in use. The vertical plate 41 is mounted on the mounting box 10, the rotating shaft 42 is rotatably connected to the vertical plate 41, the baffle 43 is fixedly connected to the rotating shaft 42, and the rotating shaft 42 passes through the vertical plate 41 and is fixedly connected to the winding roller 44.

[0054] A torsion spring is provided at the rotating shaft 42 to provide rotational elasticity. When the charging pile body 21 and the lifting platform 20 are raised, the torsion spring releases the elasticity to make the rotating shaft 42 rotate, thereby opening the baffle 43.

[0055] The bottom of the lifting platform 20 is equipped with a linkage control mechanism 6. A winding roller 44 winds a steel wire rope 47. The steel wire rope 47 passes downward through the mounting box 10, the lifting platform 20, and the linkage control mechanism 6, and is connected to a control plate 46. When the control plate 46 descends, it can drive the winding roller 44 to rotate with the help of the steel wire rope 47. The linkage control mechanism 6 includes: a mounting tube 60, a sliding tube 61, a first push ring 62, a compression spring 63, a fixed tube 64, and a second push ring 65. The mounting tube 60 and the fixed tube 64 are both fixedly connected to the lifting platform 20. The mounting tube 60 and the fixed tube 64 are located above the control plate 46. The sliding tube 61 is in sliding fit with the mounting tube 60. A first push ring 62 is installed at the lower end of the sliding tube 61. A compression spring 63 is sleeved between the sliding tube 61 and the mounting tube 60. A second push ring 65 is installed at the lower end of the fixed tube 64. When the lifting platform 20 descends, the first push ring 62 first contacts the control plate 46 to drive a baffle 43 to close. After the compression spring 63 is compressed, the second push ring 65 contacts the control plate 46 to drive another baffle 43 to close. A slot 66 is provided at the free end of the baffle 43 corresponding to the first push ring 62. A rubber strip 67 is embedded in the slot 66. A retaining strip 68 is provided at the free end of the baffle 43 corresponding to the second push ring 65. When the two baffles 43 are closed, the retaining strip 68 is embedded in the slot 66 and fits tightly with the rubber strip 67 to form a seal.

[0056] When the lifting platform 20 descends, the linkage control mechanism 6 presses the control plate 46 to pull the steel wire rope 47, driving the baffle 43 to rotate and close the opening 11; when the lifting platform 20 rises, the torsion spring drives the baffle 43 to rotate and open the opening 11. The inner wall of the mounting box 10 is provided with a first slide groove 12, and the control plate 46 slides with the first slide groove 12. The inner wall of the mounting box 10 is provided with a second slide groove 15. A sliding block 16 is fixedly connected to the lifting platform 20, and the sliding block 16 slides with the second slide groove 15.

[0057] The top of the mounting box 10 is provided with a water-blocking frame 50 at the opening 11. The water-blocking frame 50 provides a certain height to prevent water from flowing directly into the box. The edge of the baffle 43 is provided with a U-shaped frame 51. A first U-shaped rubber sheet 52 is provided inside the U-shaped frame 51 to seal with the water-blocking frame 50. A second U-shaped rubber sheet 53 is provided outside the U-shaped frame 51 to seal with the top surface of the mounting box 10. A column 13 is provided at the bottom inside the mounting box 10. A rubber block 14 is installed at the top of the column 13.

[0058] Specifically, when the charging pile is not in use, the lifting platform 20 descends to the bottom of the installation box 10, and the charging pile is completely hidden inside the box. The closing mechanism of the baffle 43 is as follows: when the lifting platform 20 descends, the linkage control mechanism 6 at its bottom presses the control plate 46 to move downward. The control plate 46 pulls the wire rope 47, forcing the winding roller 44 to rotate. The winding roller 44 drives the rotating shaft 42 to rotate, driving the baffle 43 to close the opening 11. The torsion spring is compressed and stores energy during this process. At the same time, the first U-shaped rubber sheet 52 inside the U-shaped frame 51 of the baffle 43 presses the top of the water-blocking frame 50 to form a seal on the water-blocking frame 50. The second U-shaped rubber sheet 53 outside the U-shaped frame 51 presses the top surface of the installation box 10 to form a seal on the top of the box. The rubber strip 67 embedded in the slot 66 of the clip 68 completely seals the gap between the two baffles 43 to form an interlocking seal between the baffles 43.

[0059] When charging is enabled: the drive motor 35 starts and drives the double threaded rod 31 to rotate synchronously through the worm 34, worm wheel 33, sprocket 36 and chain 37. The threaded rod 31 drives the connecting block 32 to raise the lifting platform 20. The lifting platform 20 disengages from the control board 46, the torsion spring releases its elastic force, and the torsion spring drives the rotating shaft 42 to reverse. The baffle 43 rotates and opens away from the opening 11. The lifting platform 20 rises to the highest position, and the charging pile extends out from the opening 11 for use.

[0060] The distribution and closure of the baffle 43 are as follows: When the lifting platform 20 descends, the first push ring 62 at the bottom of the mounting tube 60 first contacts the control plate 46, pulls the corresponding steel wire rope 47, and drives the first baffle 43 to close. The baffle 43 has a slot 66. The sliding tube 61 moves upward in the mounting tube 60, and the compression spring 63 stores energy. The lifting platform 20 continues to descend, and the compression spring 63 is fully compressed. The second push ring 65 at the bottom of the fixed tube 64 contacts the control plate 46, pulls the steel wire rope 47, and drives the second baffle 43 to close. The baffle 43 has a locking strip 68, which is embedded in the slot 66 to complete the interlocking seal of the baffle 43.

[0061] This invention enables the charging pile to open when it is raised and seal when it is lowered, without the need for additional sensors or control programs. It reduces costs while providing protection for the charging pile. At the same time, the step-closing baffle 43 avoids the problem of gaps that are easily generated when closing synchronously and ensures good sealing performance, significantly improving environmental adaptability.
