Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, specifically referring to a lifting charging pile. Background Technology

[0002] Amid the booming development of the new energy vehicle industry, charging piles serve as an indispensable infrastructure, providing power replenishment for vehicles.

[0003] Traditional charging stations are mostly fixed structures, making them difficult to adapt to complex usage environments. In cramped old residential areas and underground parking lots, charging stations are prone to collisions and scrapes with vehicles, leading to equipment damage or even safety accidents. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing charging piles have relatively fixed structures, making them susceptible to collision damage when used in confined spaces, thus affecting equipment operation.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A liftable charging pile includes a shell buried in the ground with an open top, and a charging pile that moves and rises within the shell. The top of the charging pile is provided with a top sealing plate for sealing the top opening of the shell. It also includes drive grooves opened on the inner sidewalls of both sides of the shell. A rack is provided on one sidewall of the drive groove. A support plate is movably arranged inside the shell. The charging pile is installed on the top wall of the support plate. A drive shaft rotates at the bottom of the support plate. Gears that mesh with the rack are fixed at both ends of the drive shaft. A drive assembly is installed on the bottom wall of the support plate for driving and locking the drive shaft. A pull cable groove is opened on the sidewall of the drive groove. A safety component is provided in the pull cable groove for safely locking the support plate.

[0006] Furthermore, a fixing plate is mounted opposite to the bottom wall of the support plate, and the drive shaft is rotatably mounted on the two sets of fixing plates.

[0007] Preferably, the bottom wall of the top sealing plate is provided with a sealing groove and a side guide frame with inclined side walls, and the top wall of the housing is provided with a sealing gasket that cooperates with the sealing groove.

[0008] Furthermore, the drive assembly includes a worm gear and a connecting plate. The worm gear passes through the drive shaft, and the connecting plate is disposed opposite to the bottom wall of the support plate. A worm gear meshing with the worm gear is rotatably disposed between the two sets of connecting plates, and a motor shaft connected to the worm gear is mounted on one set of connecting plates.

[0009] Furthermore, the safety component includes a storage tube and a safety rope. The storage tube is located at the top of the cable groove, one end of the safety rope is elastically wound inside the storage tube, and the other end of the safety rope is connected to the side wall of the support plate.

[0010] Preferably, the inner wall of the housing is provided with a sliding groove parallel to the drive groove, and a damping slider fixed to the side wall of the support plate slides within the sliding groove.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. By setting a rack and pinion and driving the drive shaft in conjunction with gears, the height of the support plate can be adjusted, which facilitates the lifting and storage of the charging pile and avoids the charging pile occupying ground space and being damaged by collision.

[0013] 2. By setting up a worm and a worm wheel, the drive shaft can be driven. At the same time, due to the self-locking characteristics of the worm wheel and the worm, the worm wheel cannot drive the worm, so the drive shaft can be locked, ensuring the stability of the support plate after the position is adjusted.

[0014] 3. By setting up a storage tube and a safety rope, the support plate can be locked and pulled in the event of a fall. At the same time, in conjunction with the sliding groove and damping slider, it can provide safety for the charging pile. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, the present invention proposes a liftable charging pile, including a housing 1 buried in the ground with an open top, and a charging pile 2 that moves and rises within the housing 1. The top of the charging pile 2 is provided with a top sealing plate 3 for sealing the top opening of the housing 1. By burying the housing 1 underground, the charging pile 2 can be raised when in use and stored back in the housing 1 when not in use, and sealed with the top sealing plate 3. This can greatly save ground space and also prevent the charging pile 2 from being damaged by external impact.

[0024] like Figure 2-4As shown, it also includes drive grooves 4 opened on the inner sidewalls of both sides of the housing 1. A rack 5 is provided on one sidewall of the drive groove 4. A support plate 6 is movably arranged inside the housing 1. The charging pile 2 is installed on the top wall of the support plate 6. A drive shaft 7 is rotatably arranged at the bottom of the support plate 6. Fixed plates 12 are installed opposite to each other on the bottom wall of the support plate 6. The drive shaft 7 is rotatably arranged on the two sets of fixed plates 12. Gears 8 that mesh with the rack 5 are fixedly connected to both ends of the drive shaft 7. A drive assembly 9 is installed on the bottom wall of the support plate 6 for driving and locking the drive shaft 7. The drive assembly 9 includes a worm gear 16 and a connecting plate 17. The worm gear 16 passes through the drive shaft 7. The connecting plate 17 is opposite to each other on the bottom wall of the support plate 6. A worm 18 that meshes with the worm gear 16 is rotatably arranged between the two sets of connecting plates 17. A motor 19 that is shaft-connected to the worm 18 is installed on one set of connecting plates 17.

[0025] When the charging pile 2 is raised for use, the motor 19 is started through the external control system, which drives the worm gear 18 to rotate. The worm gear 18 drives the worm wheel 16 to rotate, and the worm wheel 16 drives the drive shaft 7 to rotate, which in turn drives the gear 8 to rotate. Through the meshing of the gear 8 and the rack 5, and the drive shaft 7 being connected to the support plate 6 through the fixing plate 12, the support plate 6 can be raised, thus raising the charging pile 2. At the same time, after being raised, the stability of the support plate 6 can be ensured by the locking between the worm gear 18 and the worm wheel 16. After use, the motor 19 is reversed, so that the charging pile 2 can be put back into the housing 1.

[0026] like Figure 2 As shown, a pull cable groove 10 is provided on the side wall of the drive groove 4. A safety component 11 is provided in the pull cable groove 10 for locking the support plate 6. The safety component 11 includes a storage cylinder 20 and a safety rope 21. The storage cylinder 20 is located at the top of the pull cable groove 10. One end of the safety rope 21 is elastically wound into the storage cylinder 20, and the other end of the safety rope 21 is connected to the side wall of the support plate 6. In extreme cases, if the structure of the gear 8 and rack 5 is damaged or the structure of the worm gear 16 and worm 18 cannot effectively mesh, the support plate 6 will fall, and the safety rope 21 will be pulled quickly. The safety rope 21 and the storage cylinder 20 utilize the structural principle of a car seat belt. The braking mechanism uses a centrifugal brake. When the safety rope 21 is pulled out quickly, the centrifugal brake's swing block opens outward under inertia and rubs against the brake disc, generating a braking torque that quickly brakes the drum and prevents the safety rope 21 from continuing to be released. This technology is existing technology and will not be described in detail in this solution. The safety rope 21 is locked, which can effectively prevent the charging pile 2 from falling. During normal use, the safety rope 21 will extend and retract normally and will not affect the normal lifting and lowering of the support plate 6.

[0027] like Figure 2As shown, the bottom wall of the top sealing plate 3 is provided with a sealing groove 13 and a side guide frame 14 with an inclined side wall. The top wall of the housing 1 is provided with a sealing gasket 15 that cooperates with the sealing groove 13, which increases the seal between the top sealing plate 3 and the housing 1 and prevents water from entering and getting damp inside.

[0028] like Figure 3 As shown, a sliding groove 22 parallel to the drive groove 4 is provided on the inner side wall of the housing 1. A damping slider 23 fixed to the side wall of the support plate 6 slides in the sliding groove 22. It is used in conjunction with the safety rope 21 to increase the safety of the support plate 6 and limit the position of the support plate 6, thereby improving the stability of the lifting and lowering of the support plate 6.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
