Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically to a snap-fit ​​charging docking rigid chain. Background Technology

[0002] In the prior art, the patentee has previously applied for a non-destructive traction docking device for electric vehicle charging cables (authorization announcement number CN215418789U), which includes a chassis, a charging plug, and a telescopic drive device installed on the chassis and driving the charging plug to move horizontally. The telescopic drive device includes a telescopic drive chain, a gear for driving the telescopic drive chain to move in and out of the chassis and to turn, and a drive motor. A telescopic guide assembly is provided between the charging plug and the chassis. The charging plug is connected to the end of the telescopic drive chain. A cable connected to the charging plug is provided in the cavity of the telescopic drive chain.

[0003] In the above technical solution, the rigid chain has poor stability after the cable extends outward, and it needs to be used in conjunction with the telescopic guide component. After a period of use, the telescopic guide component will deform due to the gravity of the rigid chain. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a snap-fit ​​charging docking rigid chain, in which the two chains snap into each other after being removed from the chain storage box, resulting in good stability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a biting charging docking rigid chain, including a first chain, a second chain, gears that drive the first chain and the second chain to move out of the chain storage box and mesh with each other, and a matching drive motor. The key is that a charging cable receiving cavity is provided in the second chain.

[0006] Furthermore, the first chain includes a plurality of first link units and two connecting plates for connecting two adjacent first link units. The first link unit includes two parallel first chain plates and two first pins connecting the two first chain plates. The two connecting plates are connected to two adjacent first pins in the two adjacent first link units and are located inside the first chain plates.

[0007] Furthermore, first rollers that mesh with the gear are provided at both ends of the first pin.

[0008] Furthermore, the second chain includes a plurality of second link units and two inner link plates for connecting two adjacent second link units. The second link unit includes two parallel second link plates and two second pins connecting the two second link plates. The two inner link plates are connected to two adjacent second pins in the two adjacent second link units and are located inside the second link plates.

[0009] Furthermore, the second chain also includes an outer chain plate connecting shaft connecting the free ends of the two second chain plates in the second chain link unit and an inner chain plate connecting shaft connecting the free ends of the two inner chain plates. The outer chain plate connecting shaft and the inner chain plate connecting shaft in the second chain cooperate with the second pin to form a charging cable receiving cavity.

[0010] Furthermore, second rollers are provided at both ends of the second pin.

[0011] Furthermore, the free end of the first chain plate in the first chain is dovetail-shaped, and the second chain has an engagement cavity between adjacent second chain plates that matches the dovetail-shaped free end.

[0012] Furthermore, the tops of both the first chain and the second chain are connected to the connecting seat.

[0013] Furthermore, the first chain and the second chain are disposed in the same chain storage box or in their respective chain storage boxes.

[0014] The advantages of this utility model are as follows: it adopts an interlocking rigid chain and sets a charging cable receiving cavity in the second chain. During the process of the rigid chain driving the charging cable to move outward, it has good load-bearing capacity and stability, which can avoid the deformation of the matching telescopic guide component and extend the service life; after the interlocking rigid chain, the charging cable receiving cavity is located between the two chains, which can prevent other components from affecting the charging cable.

Detailed Implementation

[0019] See appendix Figure 1-3 This utility model provides an interlocking charging docking rigid chain, including a first chain, a second chain, a gear 1 that drives the first chain and the second chain to move synchronously out of the chain storage box and interlock with each other, and a matching drive motor.

[0020] The first chain and the second chain can be housed in the same chain storage box or in separate chain storage boxes. In this embodiment, gear 1 and its matching drive motor are located on one side of the first chain, driving the second chain to move simultaneously while driving the first chain to move.

[0021] See appendix Figure 1 and 2 The first chain includes multiple first chain link units and two connecting plates 2 for connecting two adjacent first chain link units. Each first chain link unit includes two parallel first chain plates 3 and two first pins 4 connecting the two first chain plates 3. The two connecting plates 2 are each connected to two adjacent first pins 4 in two adjacent first chain link units and are located inside the first chain plates 3. At both ends of each first pin 4 are first rollers 5 that mesh with gears 1. In addition to meshing with gears, the first rollers 5 also cooperate with guide rails in the chain storage box for orderly storage within the chain storage box.

[0022] See appendix Figure 1 and 3 The second chain includes multiple second chain link units, two inner chain plates 6 for connecting two adjacent second chain link units, and a charging cable receiving cavity 12 disposed within the second chain. The inner chain plates 6 have the same shape as the second chain plates 7. Each second chain link unit includes two parallel second chain plates 7 and two second pins 8 connecting the two second chain plates 7. Each inner chain plate 6 is connected to two adjacent second pins 8 in two adjacent second chain link units and is located inside the second chain plates 7. The second chain also includes an outer chain plate connecting shaft 10 connecting the free ends of the two second chain plates 7 in the second chain link unit, and an inner chain plate connecting shaft 11 connecting the free ends of the two inner chain plates 6. The outer chain plate connecting shaft 10 and the inner chain plate connecting shaft 11 cooperate with the second pins 8 to form the charging cable receiving cavity 12. The charging cable receiving cavity 12 contains a charging cable, which moves with the second chain, enabling the charging cable to be removed from and retrieved from the chain storage box. Second rollers 9 are provided at both ends of the second pins 8. The second roller 9 works in conjunction with the guide rail in the chain storage box to store items in an orderly manner.

[0023] The free end of the first chain plate 3 in the first chain is dovetail-shaped, and the second chain has a meshing cavity 13 between adjacent second chain plates 7 that matches the dovetail-shaped free end.

[0024] The tops of both the first and second chains are connected to the connector 14. The connector 14 is fixed with a charging plug, and the charging cable located in the charging cable receiving cavity 12 is connected to the charging plug.

[0025] The working process of the rigid chain of this utility model is as follows:

[0026] The drive motor drives the gear 1 to rotate, causing the first chain and the second chain to move out of the chain storage box synchronously and engage after being moved out. During the movement out, the charging cable located in the second chain will follow and move out until it reaches the preset position.

[0027] During the process of the rigid chain retracting into the storage box, the drive motor drives the gear 1 to rotate, causing the meshing rigid chains to separate and enter their respective storage compartments. During this process, the charging cable in the second chain will move to the initial position.

[0028] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the scope of protection of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention are all within the scope of protection claimed by the present invention.
