Abstract

Description

Technical Field

[0001] The present invention relates to the technical field of chargers, and in particular to a charger with adaptive adjustment. Background Art

[0002] Battery chargers are devices used to charge various batteries, primarily in cars, electric bicycles, and other battery-powered devices. Existing smart battery chargers can automatically identify the connected battery type (such as lead-acid, lithium, or nickel-metal hydride) and automatically adjust charging parameters to suit the needs of different batteries, offering the benefit of adaptive regulation.

[0003] The smart battery charger is connected to a copper clamp via two wires. Simply clamp the two clamps onto the positive and negative battery terminals to charge the battery. The clamping section of the copper clamp features an arc-shaped groove to adapt to the shape of the battery terminals. This increases the contact area between the clamp and the battery terminals, thereby improving conductivity and charging efficiency. Furthermore, this arc-shaped groove ensures the clamps are securely clamped to the terminals, reducing the possibility of loosening and enhancing charging stability and safety.

[0004] However, the arc groove on the copper clip can only fit with the pole when the copper clip is placed horizontally to clamp the pole. When the space around the upper end face of the battery installed inside the device is limited, the copper clip has to be placed vertically to the upper end face of the battery to clamp the pole. At this time, the arc groove on the copper clip is rotated 90 degrees compared to when the copper clip is placed horizontally, making it difficult to fit with the outer wall of the pole. The contact area between the copper clip and the pole will be reduced, resulting in a decrease in conductivity and affecting charging efficiency. The copper clip will also easily loosen, affecting normal charging. At the same time, since the space around the upper end face of the battery installed inside the device is limited, the heat dissipation space will also be limited. When the battery charger is charging the battery, the copper clip and the pole will generate heat. If the heat is not dissipated in time, it will affect the reliability of charging. To this end, we propose a charger with adaptive adjustment. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 8 The figure shows an adaptive charger, comprising a body 5 and two wires 4 connected to the body 5. A battery 2 is placed on the side of the body 5. The upper end of the battery 2 is symmetrically fixedly connected to a pole 1. A power transmission mechanism is provided between one end of the two wires 4 and the outer wall of the two poles 1.

[0029] The power transmission mechanism includes a connecting column 19 and a cylinder 20. One end of the connecting column 19 and the cylinder 20 is fixedly connected to the block 18 and the slider 21 respectively. The other end of the connecting column 19 is fixedly connected to the end of the wire 4. One end of the block 18 and the slider 21 is fixedly connected to the L-shaped plate 13 and the L-shaped plate 7 respectively. An elastic sliding mechanism is provided between the L-shaped plate 13 and the L-shaped plate 7. An arc plate 8 is installed between the L-shaped plate 13 and the L-shaped plate 7 through an adjustment mechanism. The inner arc surfaces of the two arc plates 8 are both fitted on the outer wall of the pole 1, and the two arc plates 8 are provided with a liquid distribution mechanism.

[0030] The outer walls of the connecting column 19 and the cylinder 20 are both fixedly covered with a rubber sleeve 3, and the wire 4 is movable through the rubber sleeve 3; specifically, by providing the rubber sleeve 3, it is convenient and safe to hold the connecting column 19 and the cylinder 20.

[0031] The elastic sliding mechanism includes a slide 10, a block 12, a slot 6 and a square groove 11. The slide 10 is opened on the side wall of the L-shaped plate 13, and the slide 10 and the slider 21 are slidably matched. A spring 9 is fixedly connected symmetrically between the inner rear end surface of the slide 10 and the rear end of the slider 21. The block 12 is fixedly connected to the upper end of the slider 21. The slot 6 is opened at the upper end of the L-shaped plate 13, and the slot 6 and the block 12 are slidably matched. The square groove 11 is opened at the front end of the L-shaped plate 13 corresponding to one end of the L-shaped plate 7.

[0032] The adjustment mechanism includes two hole slots 27, which are respectively opened on the outer walls of the L-shaped plate 13 and the L-shaped plate 7 away from the wire 4. The inner walls of the two hole slots 27 are rotatably connected with a rotating column 22, and the corresponding ends of the two rotating columns 22 are respectively fixedly connected to the outer arc surfaces of the two arc-shaped plates 8. The ends away from the two rotating columns 22 are fixedly connected to the rotating block 14, and a limiting mechanism is provided between the two rotating columns 22 and the two hole slots 27.

[0033] The limiting mechanism includes a cylindrical groove 23 and four arc grooves 26. The cylindrical groove 23 is opened on the outer wall of the rotating column 22 corresponding to the hole groove 27. The four arc grooves 26 are opened on the inner wall of the hole groove 27 in a ring array around the center of the hole groove 27. A spherical pin 25 is attached to the inner wall of the cylindrical groove 23. A spring three 24 is fixedly connected between the planar end of the spherical pin 25 and the inner wall of the cylindrical groove 23. The spherical end of the spherical pin 25 is slidably fitted with one of the arc grooves 26.

[0034] In this embodiment, first, one hand pinches the rubber sleeve 3 outside the connecting column 19 and the cylinder 20, and the cylinder 20 drives the slider 21 to slide in the slide groove 10 on the side wall of the L-shaped plate 13 toward the connecting column 19, and the slider 21 also drives the card block 12 connected to its upper end to slide in the card groove 6 opened at the upper end of the L-shaped plate 13 toward the connecting column 19, and the slider 21 also squeezes the two springs 9 connected between the slide groove 10, and the slider 21 can also drive the L-shaped plate 7 to move together, the L-shaped plate 7 will move away from the L-shaped plate 13, and the L-shaped plate 7 will drive the rotating column 22 connected to it and the arc As the curved plate 8 moves together, the curved plate 8 moves away from the curved plate 8 connected to the L-shaped plate 13, and the distance between the two curved plates 8 increases until the distance between the two curved plates 8 is greater than the distance between the pole 1. At this time, the connecting column 19 and the cylinder 20 are kept horizontal, and the two curved plates 8 are placed outside one pole 1. Then, the connecting column 19 and the cylinder 20 are released. At this time, under the action of the two springs 19, the cylinder 20 moves away from the connecting column 19, and the slider 21, L-shaped plate 7, and the curved plate 8 connected to the L-shaped plate 7 are reset, so that the two curved plates 8 can clamp one pole 1. The connecting column 19, cylinder 20, block 18, slider 21, L-shaped plate 13, L-shaped plate 7, rotating column 22 and curved plates 8 are all made of copper. Then, in the same way, another two curved plates 8 are clamped around another pole 1, and the body 5 is turned on to charge the battery 2.

[0035] When the battery 2 is installed inside the equipment and there is no space around its upper end to accommodate the horizontally placed connecting column 19 and cylinder 20, when clamping the pole 1, the connecting column 19 and cylinder 20 need to be rotated upward by ninety degrees and perpendicular to the upper end of the battery 2 to clamp the pole 1 with the two arc plates 8. The two arc plates 8 will also be rotated upward by ninety degrees. At this time, a rotating block 14 is rotated downward by ninety degrees. The rotating block 14 can drive the rotating column 22 to rotate in the corresponding hole groove 27. The rotating column 22 can drive the cylindrical groove 23, the spherical pin 25 and the spring three 24 to rotate together. The spherical end of the spherical pin 25 will squeeze the corresponding arc groove 26 in the hole groove 27, and the spherical pin 25 will slide into the cylindrical groove 23 and squeeze the spring three 24. Finally, the spherical end of the spherical pin 25 will be hidden in the cylindrical groove 23 and the spherical end of the spherical pin 25 will continue to fit with the inner wall of the hole groove 27 until the spherical pin 25 rotates to the hole groove When another arc groove 26 in 27 corresponds, under the action of spring three 24, the spherical pin 25 will be pushed out of the cylindrical groove 23 and the spherical end of the spherical pin 25 will fit in another arc groove 26. At this time, the rotating block 14 stops rotating downward by ninety degrees. After releasing the rotating block 14, under the action of spring three 24, the friction between the spherical pin 25 and the arc groove 26 can limit the rotation of the rotating column 22 to a certain extent. Then, the arc plate 8 connected to the rotating column 22 can maintain a certain fixed state after rotating downward by ninety degrees. Subsequently, the other arc plates 8 are rotated downward by ninety degrees in the same way. When the connecting column 19 and the cylinder 20 are placed vertically, the inner arc surface of the arc plate 8 is still convenient to fit with the outer wall of the pole 1, thereby avoiding the reduction of contact area leading to a decrease in conductive performance, improving charging efficiency, and improving the firmness of clamping to avoid affecting normal charging.

[0036] Example 2: Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 , this embodiment further explains Example 1. The liquid distribution mechanism in the figure includes an arc-shaped shell 15 and a plurality of liquid guide grooves 17. The arc-shaped shell 15 is fixedly connected to the upper end of the arc-shaped plate 8. The plurality of liquid guide grooves 17 are arranged on the inner arc-shaped surface of the arc-shaped plate 8 along the inner arc-shaped surface of the arc-shaped plate 8. The inner arc-shaped surface of the arc-shaped shell 15 is respectively provided with leakage holes 28 near the plurality of liquid guide grooves 17. The upper end of the arc-shaped shell 15 is slidably interspersed with an arc-shaped block 33. The lower end of the arc-shaped block 33 is fixedly connected to an arc-shaped rubber block 34. The arc-shaped block 33 and the arc-shaped rubber block 34 are both in contact with the inner wall of the arc-shaped shell 15. The upper end of the arc-shaped block 33 is fixedly connected to an arc-shaped rubber plate 16. An elastic component is provided between the arc-shaped rubber plate 16 and the arc-shaped shell 15.

[0037] The elastic component includes two splicing blocks 30, which are symmetrically fixedly connected to the outer curved surface of the arc-shaped shell 15. The inner walls of the two splicing blocks 30 are slidably interspersed with guide pillars 31, and the upper ends of the two guide pillars 31 are fixedly connected to the lower end of the arc-shaped rubber plate 16. The outer walls of the two guide pillars 31 are slidably sleeved with springs 29, and the two springs 29 are respectively fixedly connected between the upper ends of the two splicing blocks 30 and the lower end of the arc-shaped rubber plate 16.

[0038] A rubber plug 32 is slidably inserted into one end of the arc-shaped shell 15 ; specifically, the conductive liquid can be added to the interior of the arc-shaped shell 15 by pulling out the rubber plug 32 , and then the rubber plug 32 is tightly inserted into the inner wall of the arc-shaped shell 15 to seal the arc-shaped shell 15 .

[0039] In this embodiment, when the two curved plates 8 clamp the corresponding pole 1, the two curved rubber plates 16 are pushed upward in sequence, and the curved rubber plates 16 drive the two guide posts 31 to slide upward in the two splicing blocks 30 respectively, and the curved rubber plates 16 stretch the spring 29 connected to the splicing blocks 30, and the curved rubber plates 16 drive the curved block 33 to slide upward in the curved shell 15, and the curved block 33 drives the curved rubber block 34 to move upward. At this time, the curved rubber block 34 no longer Once the leakage holes 28 are sealed, the conductive liquid in the arc-shaped shell 15 will leak out along the multiple leakage holes 28 and flow into the multiple liquid guide grooves 17. The liquid guide grooves 17 are located between the inner curved surface of the arc-shaped plate 8 and the outer wall of the pole 1. The arc-shaped rubber plate 16 is then released. Under the force of the second spring 29, the arc-shaped rubber plate 16, the two guide pillars 31, the arc block 33, and the arc-shaped rubber block 34 all move downward and return to their original position. The arc-shaped rubber block 34 will continue to seal the multiple leakage holes 28 to prevent leakage. The connecting column 19 and the cylinder 20 are then rotated back and forth, causing the two arc-shaped plates 8 to rotate back and forth, thereby evenly applying the conductive liquid to the inner curved surfaces of the two arc-shaped plates 8 and the outer wall of the pole 1.

[0040] It should be noted that the conductive liquid can improve the quality of the contact surface and reduce the contact resistance. Lower contact resistance means less heat generated when current passes through, which indirectly reduces the heat generated at the contact point, thereby reducing heat accumulation and improving charging reliability.
