Description

Technical Field

[0001] This application relates to the field of battery technology, and more particularly to a battery connection mechanism. Background Technology

[0002] In modern society, batteries are widely used in various fields as an important energy storage device. The performance and reliability of batteries directly affect the normal operation of related equipment. As a key connection component between batteries and external equipment, the design and performance of battery connection mechanisms play a crucial role in the effectiveness of battery use.

[0003] In the existing technology, the traditional battery pack connection usually involves first fixing two batteries to the support frame, and then connecting the two batteries in series and energizing them through electrical wires. However, in this connection method, it is quite troublesome to disassemble and reassemble the battery pack and the series wires. In addition, the two series wires do not have a self-locking function. During use, shaking or repeated disassembly and reassembly of the wires can easily cause the connection to loosen and make poor contact.

[0004] Alternatively, complex fixing devices can be used to connect the two batteries. For example, CN222507877U discloses a battery fixing device, battery assembly, and operating machinery. The battery fixing device is suitable for fixing a first and a second battery that are spaced apart vertically. It includes: a chassis suitable for placing the first battery; multiple support rods, one end of which is mounted on the chassis and suitable for surrounding the first battery; a tray mounted on the other end of the support rods and leaving a gap with the upper surface of the first battery, suitable for placing the second battery; and a limiting component mounted on the tray and suitable for surrounding the second battery and its upper surface. In this technical solution, the limiting component may experience irreversible wear at the contact points when used in vibration environments such as vehicles. Once the limiting structure is severely worn, it will affect the accuracy and reliability of the limiting, making the connection between the battery clip and the terminal unstable, and may even lead to the battery clip accidentally falling off, thereby reducing the stability and safety of the battery connection.

[0005] Based on the above-mentioned existing technology, there are technical problems that urgently need to be solved, such as unstable connection or loosening of the connection structure during the connection of two batteries, which leads to poor battery contact and reduced stability and safety. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a battery connection mechanism, including a main body box for accommodating two battery packs;

[0007] The main body box has a mounting groove on its side wall. Multiple connecting holes are provided on both sides of the inner wall of the mounting groove. A connecting component is provided on the inner wall of the mounting groove. The connecting component is set in the mounting groove through the connecting holes. The connecting component is used to connect the lines of the two battery blocks and realize the connection and disconnection of the connecting line between the two battery blocks.

[0008] The side wall of the main box is provided with an adjustment groove, which is used to prevent the two battery blocks from shaking during use and to improve the stability of the connection between the two battery blocks.

[0009] Furthermore, the connection component includes:

[0010] Multiple support frames are fixedly connected to the inner wall of the mounting slot;

[0011] The connecting pipe is installed on the inner wall of the support frame, and its surface is fixedly connected to a limit ring and slidably connected to a sliding ring;

[0012] The first spring is sleeved on the surface of the connecting pipe, and its two ends are fixed to the sliding ring and the limiting ring, respectively.

[0013] Multiple tapered holes are formed on the surface of the connecting pipe, and sliding balls are provided on the inner wall;

[0014] The first clearance groove is formed on the inner wall of the sliding ring;

[0015] The first connector is slidably connected to the inner wall of the connecting tube and connected to the support ring via the second spring;

[0016] An insertion tube is installed on the inner wall of the support frame, and a second connector is fixed on its inner wall. A second clearance groove matching the sliding ball is opened on its surface.

[0017] The insertion tube and the connecting tube are movably connected to achieve self-locking and connection or disconnection of the line;

[0018] Specifically, the connecting assembly includes multiple support frames, which are fixedly connected to the inner wall of the mounting groove. A connecting tube is provided on the inner wall of each support frame. A limiting ring is fixedly connected to the surface of the connecting tube, and a sliding ring is slidably connected to the surface of the connecting tube. A first spring is sleeved on the surface of the connecting tube, with one end of the first spring fixedly connected to the inner wall of the sliding ring and the other end of the first spring fixedly connected to one end of the limiting ring. Multiple tapered holes are formed on the surface of the connecting tube, and sliding balls are provided on the inner walls of the tapered holes. A first clearance groove is formed on the inner wall of the sliding ring. A first connector is slidably connected to the inner wall of the connecting tube. A support ring is fixedly connected to the inner wall of the connecting tube. A second spring is fixedly connected to one end of the first connector, and the other end of the second spring is fixedly connected to one end of the support ring. An insertion tube is provided on the inner wall of the support frame, and a second connector is fixedly connected to the inner wall of the insertion tube. A second clearance groove is formed on the surface of the insertion tube, and the inner wall size of the second clearance groove matches the surface size of the sliding ball. The surface of the insertion tube is movably sleeved with the inner wall of the connecting tube.

[0019] This causes the sliding ring to push the insertion tube into the interior of the connecting tube, that is, to connect the circuits of the two battery blocks through the connecting wire, the first connector and the second connector, thereby realizing the connection and disconnection of the connecting wire between the two battery blocks, and realizing the self-locking of the connecting tube to the insertion tube, thereby preventing poor contact between the two battery blocks due to prolonged use or shaking during use.

[0020] Furthermore, the adjusting groove is provided on and / or inside with:

[0021] A baffle plate is fixed to the inner wall of the adjustment groove;

[0022] Two first limiting plates are fixedly connected to the inner top surface of the adjusting groove;

[0023] A threaded column is rotatably connected to a baffle plate, its surface is threaded to the inner wall of the first limiting plate and slidably connected to a spur gear;

[0024] The first sliding groove is located on the inner top surface of the adjusting groove;

[0025] The L-shaped strip is slidably connected to the first limiting plate and the first sliding groove, and meshes with the spur gear through the tooth groove;

[0026] Two second limiting plates are located on the inner wall of the main body box and are fixedly connected to the top surface of the L-shaped strip for clamping the battery block;

[0027] Bolts, threaded connections to threaded posts, with their sidewalls abutting against the sidewalls of the baffle plate;

[0028] Specifically, a baffle plate is fixedly connected to the inner wall of the adjusting groove, and a threaded column is rotatably connected to the inner wall of the baffle plate. A first sliding groove is formed on the inner top surface of the adjusting groove. Two first limiting plates are fixedly connected to the inner top surface of the adjusting groove. An L-shaped strip is slidably connected to the surface of the first limiting plate, and the L-shaped strip is slidably connected to the inner wall of the first sliding groove. Two second limiting plates are provided on the inner wall of the main body box. The bottom surface of the second limiting plate is fixedly connected to the top surface of the L-shaped strip. The surface of the threaded column is threadedly connected to the inner wall of the first limiting plate. A spur gear is slidably connected to the surface of the threaded column. A toothed groove is formed on the surface of the L-shaped strip. The surface of the spur gear meshes with the surface of the L-shaped strip. A bolt is threadedly connected to the surface of the threaded column, and the side wall of the bolt abuts against the side wall of the baffle plate.

[0029] Rotating the threaded column can drive the limiting block to rotate, and the rotation of the limiting block can drive the two L-shaped strips to move in opposite directions, thereby driving the two second limiting plates to clamp the two battery blocks, thus preventing the two battery blocks from shaking during use, which would affect the poor contact of the connection lines between the two battery blocks, thereby improving the stability of the connection between the two battery blocks.

[0030] Rotating the threaded post can also drive the spur gear to rotate, thereby causing the second limiting plate to clamp the two battery blocks. The bolts provided make it easy to fix the threaded post, thereby preventing the second limiting plate from moving on its own.

[0031] Furthermore, a limit block is fixed to the inner wall of the spur gear, which slides in conjunction with the second sliding groove of the threaded column to achieve linkage;

[0032] Specifically, the surface of the threaded column has two second sliding grooves, and the inner wall of the spur gear is fixedly connected to two limiting blocks. The limiting blocks are slidably connected to the inner wall of the second sliding grooves. The second sliding grooves and the limiting blocks cooperate with each other to make the threaded column rotate, which in turn drives the spur gear to rotate.

[0033] Furthermore, the top surface of the main body box is provided with a sliding hole, and the inner wall is slidably connected with a sliding plate with a pull hole for easy removal;

[0034] Specifically, the top surface of the main body box is provided with a sliding hole, the inner wall of the sliding hole is slidably connected to a sliding plate, and the side wall of the sliding plate is provided with a pull hole. The sliding hole facilitates the removal of the sliding plate.

[0035] Furthermore, the inner wall of the battery block is fixed with multiple connecting wires, one end of which is connected to the second connector and the other end of which is connected to the first connector;

[0036] Specifically, the inner wall of the battery block is fixedly connected with multiple connecting wires. One end of the connecting wire located at one end of the connecting assembly is fixedly connected to the inner wall of the second connector, and one end of the connecting wire located at the other end of the connecting assembly is fixedly connected to the inner wall of the first connector. The multiple connecting wires facilitate the circuit connection between the two battery blocks.

[0037] Furthermore, multiple heat dissipation holes of matching size are provided on both sides of the main body box;

[0038] Specifically, the heat dissipation holes facilitate heat dissipation for the two battery packs located inside the main casing.

[0039] Furthermore, rotating the threaded column can drive the L-shaped bar to move in the opposite direction, thereby causing the second limiting plate to clamp and fix the battery block.

[0040] Furthermore, the sliding ball enters the first clearance groove when the insertion tube is inserted, and after reaching its position, it locks into the second clearance groove to achieve self-locking.

[0041] Furthermore, the bolt secures the threaded post by abutting against the side wall of the baffle plate.

[0042] Furthermore, during the use of the battery connection mechanism, the insertion tube is inserted into the inner wall of the connecting tube by pushing the sliding ring through the connecting tube. When the sliding ring slides to the right, it pushes the first spring, causing the first spring to contract. When the insertion tube enters the interior of the connecting tube, the surface of the insertion tube pushes the sliding ball, causing the sliding ball to enter the inner wall of the first clearance groove. After the insertion tube is in place, the sliding ring is released, allowing the sliding ball to enter the inner wall of the second clearance groove, thereby achieving self-locking of the connecting tube to the insertion tube. At the same time, it also facilitates the quick connection and disconnection of the second connector and the first connector, avoiding poor contact between the two batteries due to prolonged use or shaking during use. Through the first limiting plate, rotating the threaded column causes the limiting block to rotate. The rotation of the limiting block causes the two L-shaped bars to move in opposite directions, thereby causing the two second limiting plates to clamp the battery block, thus preventing the battery block from shaking during use and affecting the poor contact of the connection line between the two battery blocks, thereby improving the stability of the connection between the two battery blocks.

[0043] The beneficial effects of this utility model are as follows:

[0044] This application provides a battery connection mechanism, including a main housing for accommodating two battery packs;

[0045] The main body box has a mounting groove on its side wall. Multiple connecting holes are provided on both sides of the inner wall of the mounting groove. A connecting component is provided on the inner wall of the mounting groove. The connecting component is set in the mounting groove through the connecting holes. The connecting component is used to connect the lines of the two battery blocks and realize the connection and disconnection of the connecting line between the two battery blocks.

[0046] The side wall of the main box is provided with an adjustment groove, which is used to prevent the two battery blocks from shaking during use and to improve the stability of the connection between the two battery blocks.

[0047] By using self-locking connection components and adjustable adjustment slots, the problem of loosening and poor contact in traditional battery connection methods is effectively solved. At the same time, heat dissipation and maintenance convenience are optimized, improving the stability and service life of the battery pack. Attached Figure Description

[0077] Two first limiting plates 23 are fixedly connected to the inner top surface of the adjusting groove 19;

[0078] The threaded column 21 is rotatably connected to the baffle plate 20, and its surface is threadedly connected to the inner wall of the first limiting plate 23 and slidably connected to the spur gear 27.

[0079] The first sliding groove 22 is located on the inner top surface of the adjusting groove 19;

[0080] The L-shaped strip 24 is slidably connected to the first limiting plate 23 and the first sliding groove 22, and meshes with the spur gear 27 through the toothed groove 25;

[0082] Bolt 35 is threaded to threaded post 21, and its sidewall abuts against the sidewall of baffle plate 20;

[0083] Specifically, in this embodiment, a baffle plate 20 is fixedly connected to the inner wall of the adjusting groove 19, and a threaded column 21 is rotatably connected to the inner wall of the baffle plate 20.

[0084] Rotating the threaded post 21 can drive the limiting block 34 to rotate. The rotation of the limiting block 34 can drive the two L-shaped bars 24 to move in opposite directions, thereby driving the two second limiting plates 26 to clamp the two battery blocks 2, thus preventing the two battery blocks 2 from shaking during use, which would affect the poor contact of the connection lines between the two battery blocks 2, thereby improving the stability of the connection between the two battery blocks 2.

[0085] Rotating the threaded post 21 can also drive the spur gear 27 to rotate, thereby causing the second limiting plate 26 to clamp the two battery blocks 2. The bolts 35 make it easy to fix the threaded post 21, thereby preventing the second limiting plate 26 from moving on its own.

[0086] The inner wall of the spur gear 27 is fixed with a limit block 34, which slides with the second sliding groove 33 of the threaded column 21 to achieve linkage.

[0087] Specifically, in this embodiment, two second sliding grooves 33 are formed on the surface of the threaded column 21, and two limiting blocks 34 are fixedly connected to the inner wall of the spur gear 27. The limiting blocks 34 are slidably connected to the inner wall of the second sliding grooves 33. By using the second sliding grooves 33 and the limiting blocks 34 in cooperation with each other, the threaded column 21 can rotate to drive the spur gear 27 to rotate.

[0088] The top surface of the main body box 1 is provided with a sliding hole 28, and the inner wall is slidably connected with a sliding plate 29 with a hand pull hole for easy removal;

[0089] Specifically, in this embodiment, a sliding hole 28 is provided on the top surface of the main body box 1, and a sliding plate 29 is slidably connected to the inner wall of the sliding hole 28.

One end of the left connecting wire 31 is fixedly connected to the inner wall of the second connector 17, and one end of the right connecting wire 31 is fixedly connected to the inner wall of the first connector 13. The connecting wires 31 facilitate the circuit connection between the two battery blocks 2.

[0092] The main body box 1 has multiple heat dissipation holes 23 of matching size on both sides;

[0093] Specifically, in this embodiment, the heat dissipation holes 23 and multiple heat dissipation holes 32 are matched in size, which facilitates heat dissipation for the two battery blocks 2 located inside the main body box 1.

[0094] Rotating the threaded post 21 can drive the L-shaped bar 24 to move in the opposite direction, thereby causing the second limiting plate 26 to clamp and fix the battery block 2.

[0095] The sliding ball 11 enters the first clearance groove 12 when the insertion tube 16 is inserted, and after it is in place, it is locked into the second clearance groove 18 to achieve self-locking.

[0096] The bolt 35 secures the threaded post 21 by abutting against the side wall of the baffle plate 20.

[0097] During the use of the battery connection mechanism, the insertion tube 16 is inserted into the inner wall of the connecting tube 6 by pushing the sliding ring 8 through the connecting tube 6. When the sliding ring 8 slides to the right, it pushes the first spring 9, causing the first spring 9 to contract. When the insertion tube 16 enters the interior of the connecting tube 6, the surface of the insertion tube 16 pushes the sliding ball 11, causing the sliding ball 11 to enter the inner wall of the first clearance groove 12. After the insertion tube 16 is in place, the sliding ring 8 is released, allowing the sliding ball 11 to enter the inner wall of the second clearance groove 18, thereby achieving self-locking of the connecting tube 6 to the insertion tube 16. This also facilitates the implementation of the second clearance groove 18. The quick connection and disconnection of connector 17 and first connector 13 prevents poor contact between the two battery cells due to prolonged use or shaking during use. By rotating the threaded post 21 through the first limiting plate 23, the limiting block 34 can be rotated. The rotation of the limiting block 34 can drive the two L-shaped bars 24 to move in the opposite direction, thereby driving the two second limiting plates 26 to clamp the battery cell 2. This prevents the shaking of the battery cell 2 during use from affecting the poor contact of the connection line between the two battery cells 2, thereby improving the stability of the connection between the two battery cells 2.
