Description

Technical Field

[0001] This utility model relates to the technical field of copper busbar flexible connection, and in particular to a safe charging pile battery flexible connection device with adjustable length. Background Technology

[0002] Copper busbar flexible connectors are conductive structures mainly used for flexible connections in various high-voltage electrical appliances, vacuum electrical appliances, mining explosion-proof switches, and related products such as automobiles and locomotives. They are made of bare copper wire or tinned copper braided wire (stranded wire) using a cold pressing method. Currently, in the field of new energy vehicle charging piles, they can be used as conductive structures for the internal batteries of charging piles, providing better heat dissipation and conductivity for the batteries.

[0003] Most existing flexible connections are integrated structures, which means that when installing different models of charging pile batteries, the length of the integrated flexible connection is the same, making it difficult to flexibly adapt to different models of charging pile batteries. This results in poor universality and room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-length, safe charging pile battery flexible connection device to solve the problem mentioned in the background art that most existing copper busbar flexible connections are integrated structures, which makes them difficult to adapt to different models of charging pile batteries and result in poor installation flexibility.

The left and right sides of the protective frame are provided with strip-shaped holes adapted to the first copper busbar and the second copper busbar. The opposite sides of the first copper busbar and the second copper busbar are fixedly connected with connection terminals. An adjustment component is fixedly connected to the inner bottom wall of the protective frame. A driving component is fixedly connected to the front of the protective frame. A locking component is fixedly connected to the front of the driving component. The adjustment component is used to change the length between the first copper busbar and the second copper busbar, the drive component is used to manually change the distance, and the locking component is used to lock the drive component to ensure that the position of the adjustment component does not shift.

A right-angle bracket is slidably connected to the inner bottom wall of the strip frame. A locking hole is provided on the front of the right-angle bracket. The right-angle bracket is slidably connected to the inner walls of the two strip grooves respectively. A driving rod is fixedly connected to the back of the right-angle bracket. The rear end of the driving rod extends into the interior of the protective frame and is fixedly connected to the front of the movable copper busbar.

[0009] Preferably, a cover plate is attached to the upper surface of the strip frame at the position corresponding to the strip groove. Mounting plates are fixedly connected to both sides of the cover plate. Two locking bolts are threaded to the upper surface of each mounting plate, and four threaded grooves that are compatible with the locking bolts are opened on the upper surface of the strip frame.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an adjustable length safety charging pile battery soft connection device, including a protective frame 1, a first copper busbar 2 and a second copper busbar 3. The left and right sides of the protective frame 1 are provided with strip-shaped holes adapted to the first copper busbar 2 and the second copper busbar 3. The back sides of the first copper busbar 2 and the second copper busbar 3 are fixedly connected with connecting terminals 4. The inner bottom wall of the protective frame 1 is fixedly connected with an adjustment component 5. The front side of the protective frame 1 is fixedly connected with a driving component 6. The front side of the driving component 6 is fixedly connected with a locking component 7. Adjustment component 5 is used to change the length between the first copper busbar 2 and the second copper busbar 3, drive component 6 is used to manually change the distance, and locking component 7 is used to lock drive component 6 to ensure that the position of adjustment component 5 does not shift.

[0017] Furthermore, the adjustment component 5 includes a positioning copper busbar 501, the right side of which is fixedly connected to the left side of the second copper busbar 3. A movable copper busbar 502 is slidably connected to the inner bottom wall of the protective frame 1, the left side of which is fixedly connected to the right side of the first copper busbar 2. The positioning copper busbar 501 and the movable copper busbar 502 are provided with meshing grooves on their opposite surfaces. The positioning copper busbar 501 and the movable copper busbar 502 mesh with each other through the meshing grooves. The movable copper busbar 502 can move relative to the positioning copper busbar 501 through the meshing grooves, thereby increasing the length of the first copper busbar 2.

[0018] Furthermore, the drive assembly 6 includes a strip frame 601, with strip grooves on both its upper and back surfaces. A right-angle bracket 602 is slidably connected to the inner bottom wall of the strip frame 601. A locking hole is provided on the front of the right-angle bracket 602. The right-angle bracket 602 is slidably connected to the inner walls of the two strip grooves respectively. A drive rod 603 is fixedly connected to the back of the right-angle bracket 602. The rear end of the drive rod 603 extends into the interior of the protective frame 1 and is fixedly connected to the front of the movable copper busbar 502. A cover plate 604 overlaps on the upper surface of the strip frame 601 at a position corresponding to the strip groove. Mounting plates 605 are fixedly connected to both sides of the cover plate 604. The upper surface of the frame 601 is threaded with two locking bolts 606, and the upper surface of the frame 601 has four threaded grooves that are compatible with the locking bolts 606. After the cover plate 604 is removed by the two mounting plates 605 and the four locking bolts 606, the lateral position of the movable copper busbar 502 can be changed by the right angle bracket 602 and the drive rod 603. During the movement of the movable copper busbar 502, it will never disengage from the engagement groove on the left side of the positioning copper busbar 501, thus ensuring that the current can pass through normally. After the movable copper busbar 502 moves to the left, the length of the first copper busbar 2 can be increased, so that it can be used for different models of charging pile batteries, which is highly flexible.

[0019] Furthermore, the locking assembly 7 includes a locking frame 701, which is fixedly connected to the front of the strip frame 601. The back of the locking frame 701 extends into the interior of the strip frame 601. Two positioning rods 702 are fixedly connected to the inner wall of the locking frame 701, and springs 703 are fitted onto the surfaces of both positioning rods 702. A locking plate 704 is slidably connected to the inner wall of the locking frame 701. A pull rod 705 is fixedly connected to the front of the locking plate 704, with the front end of the pull rod 705 extending into the front of the locking frame 701. Several locking blocks 706 are fixedly connected to the back of the locking plate 704, and the locking blocks 706 are adapted to the locking holes. The locking plate 704 is slidably connected to the surfaces of the two positioning rods 702 respectively. The front ends of both springs 703 overlap with the inner front wall of the locking frame 701, and the rear ends of both springs 703 overlap with the front of the locking plate 704. Pulling the lever 705 forward can move the locking plate 704 forward, causing the locking block 706 to disengage from the inside of the strip frame 601. At the same time, it can also compress the two springs 703 to deform them. At this time, the right-angle bracket 602 can move. After the position of the right-angle bracket 602 is confirmed, the lever 705 is released. Through the reaction force generated by the springs 703, the locking plate 704 is moved back to its original position. The locking plate 704 then causes the locking block 706 to insert into the locking hole on the front of the right-angle bracket 602, thereby locking the position of the right-angle bracket 602 and the movable copper busbar 502.

[0020] Working principle: First, based on the distance and position of the charging pile battery, after confirming the appropriate length, remove the four locking bolts 606 and the cover plate 604, exposing the right-angle bracket 602. Pulling the lever 705 forward moves the locking plate 704 forward, causing the locking block 706 to disengage from the locking hole. This causes the two springs 703 to lose their deformation, and the right-angle bracket 602 is no longer restricted. Pushing the right-angle bracket 602 to the left on the strip frame 601 moves the movable copper busbar 502 to the left within the engagement groove on the left side of the positioning copper busbar 501, thereby extending the length of the first copper busbar 2 and increasing the overall length of the flexible connection. The design offers high flexibility and can be adapted to different models of charging pile batteries. After adjustment, the right-angle bracket 602 and the pull rod are released. At this time, the two springs 703 lose their restraint and generate a reaction force, which drives the locking block 706 to move backward through the locking plate 704 until the locking block 706 is engaged in the locking hole on the front of the right-angle bracket 602, locking the position of the movable copper busbar 502. At this time, the cover plate 604 is fixed by the mounting plate 605 and the locking bolt 606 to protect the inside of the protective frame 1. The locking block 706 can ensure that the position of the movable copper busbar 502 will not move, making it safer when the copper busbar carries current.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
