Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, and particularly relates to a wire winding disc for a charging pile. Background Art

[0002] An electric vehicle refers to a vehicle that uses an on-vehicle power source and drives the wheels with an electric motor, meeting the requirements of road traffic and safety regulations. Since electric vehicles have relatively less impact on the environment than traditional vehicles, their prospects are widely optimistic. In recent years, the popularity rate of electric vehicles has been increasing, and the problem of how to charge electric vehicles in a timely and effective manner has also emerged, and a suspended-rail charging pile has emerged as the times require.

[0003] Currently, for existing charging piles, generally, the rotation of a wire winding disc driven by a motor is used to achieve the winding of a cable. However, when the cable is led out or wound in, due to the inertia of the rotation of the wire winding disc, the led-out or wound-in cable will become loose, thus affecting the smoothness of the cable during operation.

[0004] The above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is the closest prior art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above deficiencies and provide a wire winding disc for a charging pile.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme: A wire winding disc for a charging pile includes a first end plate and a second end plate that are spaced front and rear and are equipped with a wire winding disc. Between the first end plate and the second end plate and on one side of the wire winding disc, there is a guiding frame for the cable to pass through, and further includes:

[0007] A fixing mechanism for limiting the position of the cable wound around the outer peripheral surface of the wire winding disc.

[0008] Further, the fixing mechanism includes:

[0009] An upper limiting mechanism for limiting the upper part of the cable wound around the outer peripheral surface of the wire winding disc;

[0011] Further, the upper limiting mechanism and the lower limiting mechanism have the same structure, and both include:

[0012] A cross plate detachably arranged between the first end plate and the second end plate;

[0013] An arc plate spaced inside the cross plate and used for closely adhering to the surface of the cable on the outer peripheral surface of the wire winding disc;

[0014] Extrusion components, multiple and arranged adjacent to each other on the frame formed by the combination of the horizontal plate and the arc plate, for tightly fitting the cables bundled on the winding disc.

[0015] Furthermore, several adjacent groove plates are detachably arranged on the winding disc.

[0016] Furthermore, the extrusion component includes:

[0017] Arc blocks, arranged in any one of the adjacent grooves opened on the arc plate, for enabling the cables bundled on the groove plate to pass through the inner arc surface of the arc block and closely adhere to prevent the cables from loosening;

[0018] Support blocks, arranged in any one of the adjacent grooves opened on the horizontal plate and corresponding to the arc blocks, for supporting and connecting each corresponding arc block;

[0019] Vertical plates, arranged on the outer arc surface of the arc block and slidably arranged through the corresponding support blocks;

[0020] Side plates, arranged on the part of the side surface of the vertical plate protruding from the horizontal plate;

[0021] Springs, arranged between the side plates and the support blocks and evenly provided with multiple, for elastically supporting the arc blocks on the support blocks through the combined side plates and vertical plates;

[0022] Guide rods, correspondingly arranged in the springs and slidably arranged with the upper ends penetrating the end surfaces of the side plates, for providing stable axial support for the springs connected between the side plates and the support blocks.

[0023] Furthermore, several limiting rollers for restricting the movement of the cables are rotatably arranged between the first end plate and the second end plate.

[0024] Compared with the prior art, the present utility model has the following beneficial effects: Through the fixed mechanism provided in the present utility model, when the cables are led out or wound up, the frictional force between the arc plate and the cables can effectively eliminate the rotational inertia of the winding disc, thereby effectively preventing the cables from becoming loose when being led out or wound up, and further ensuring the smoothness of the cables when being led out or wound up; and through the extrusion components corresponding to the groove plates one by one, the cables placed in the groove plates can be separated and pressed, solving the problem of cable loosening caused by the height difference of the cables bundled between adjacent groove plates.

[0034] As Figures 1-4 shown, a cable winding disc of the present utility model is applied to a suspension rail type charging pile, and includes a first end plate 1 and a second end plate 2 which are spaced front and rear and are assembled with a winding disc 3. A guide frame 4 for the cable to pass through is arranged between the first end plate 1 and the second end plate 2 and on one side of the winding disc 3. It further includes:

[0035] A fixing mechanism 5 for position-limiting the cable wound around the outer peripheral surface of the winding disc 3.

[0036] In specific implementation, through the fixing mechanism 5, when the cable is paying out or taking up, the frictional force between the structure formed on the fixing mechanism 5 and the cable can eliminate the rotational inertia of the winding disc 3, thereby effectively preventing the cable from becoming loose when paying out or taking up, and further ensuring the smoothness of the cable when paying out or taking up. Moreover, the pressing components 53 formed on the fixing mechanism 5 correspond to the groove plates 31 formed on the winding disc 3 one by one, solving the problem of cable looseness caused by the height difference of the cables wound between adjacent groove plates 31, and further ensuring the smoothness of the cable when paying out or taking up.

[0037] In one embodiment, the fixing mechanism 5 includes:

[0038] An upper limiting mechanism for limiting the upper part of the cable wound around the outer peripheral surface of the winding disc 3;

[0039] A lower limiting mechanism for limiting the lower part of the cable wound around the outer peripheral surface of the winding disc 3. With such a design, through the upper limiting mechanism and the lower limiting mechanism which are symmetrically arranged up and down and assembled with bolts between the first end plate 1 and the second end plate 2, the upper and lower parts of the cable wound around the outer peripheral surface of the winding disc 3 can be synchronously limited, and the cable wound around the winding disc 3 can be pressed tightly.

[0040] In one embodiment, the upper limit mechanism and the lower limit mechanism have the same structure, and both include:

[0041] A cross plate 51 detachably arranged between the first end plate 1 and the second end plate 2;

[0042] An arc plate 52 spaced inside the cross plate 51 for closely adhering to the surface of the cable on the outer peripheral surface of the winding disc 3;

[0043] A plurality of extrusion assemblies 53 are adjacently arranged on the frame body formed by the combination of the cross plate 51 and the arc plate 52 for tightly fitting the cables bundled on the winding disc 3. With this design, by using the cross plate 51 assembled with bolts between the first end plate 1 and the second end plate 2, the arc plate 52 adhered to the cable inside the cross plate 51, and the extrusion assemblies 53 combined in a plurality of grooves machined adjacent to each other on the cross plate 51 and the arc plate 52, it is possible to not only limit the cables at the same arc height as a whole, but also perform independent regional limiting on the cables bundled on the winding disc 3 without being restricted by the whole.

[0044] In one embodiment, a plurality of adjacent groove plates 31 are detachably arranged on the winding disc 3. With this design, it is convenient to bundle the cables in separate areas on the winding disc 3, so that the cables can perform outgoing or incoming operations corresponding to the groove plates 31.

[0045] In one embodiment, the extrusion assembly 53 includes:

[0046] An arc block 531 arranged in any one of the adjacent grooves opened on the arc plate 52 for enabling the cables bundled on the groove plate 31 to closely adhere through the inner arc surface of the arc block 531 and preventing the cables from loosening;

[0047] A support block 532 arranged in any one of the adjacent grooves opened on the cross plate 51 and corresponding to the arc block 531 for supporting and connecting each corresponding arc block 531;

[0048] A vertical plate 533 arranged on the outer arc surface of the arc block 531 and slidably arranged through the corresponding support block 532;

[0049] A side plate 534 arranged on a part of the side surface of the vertical plate 533 protruding from the cross plate 51;

[0050] A spring 535 is arranged between the side plate 534 and the support block 532 and a plurality of springs are evenly arranged, for enabling the arc block 531 to be elastically supported on the support block 532 through the combined side plate 534 and vertical plate 533;

[0051] The guide rod 536 is correspondingly arranged inside the spring 535 and its upper end is slidably arranged through the end face of the side plate 534, and is used to provide stable axial support for the spring 535 connected between the side plate 534 and the support block 532. With such a design, during the operation of wire outlet or wire winding, due to the length problem of the cable, the arc height of the cable wound on the winding disc 3 is inconsistent. At this time, the arc block 531 assembled in the groove machined on the arc plate 52, the vertical plate 533 and the side plate 534 sequentially welded on the arc block 531, and the plurality of springs 535 welded between the support blocks 532 assembled in the grooves machined on the side plate 534 and the cross plate 51 and the guide rod 536 sleeved inside the spring 535 and welded on the end face of the support block 532 can axially support and individually limit and press the cable wound in the corresponding groove plate 31, effectively preventing the cable from becoming loose during wire outlet or wire winding, and thus ensuring the smoothness of the cable during wire outlet or wire winding.

[0052] In one embodiment, several limiting rollers 6 for restricting the movement of the cable are rotatably arranged between the first end plate 1 and the second end plate 2. With such a design, by using bearings to rotatably connect several limiting rollers 6 evenly distributed on the outer periphery of the winding disc 3 between the first end plate 1 and the second end plate 2, the cable can be restricted to a limited movement area during the operation of wire outlet or wire winding of the cable, effectively avoiding the problem of the cable breaking away.

[0053] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
