Description

A lithium battery pack with a quick-connection structure Technical Field

[0001] This invention relates to the field of lithium battery installation technology, and more specifically, to a lithium battery pack with a quick-connection structure. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Therefore, these batteries are also called lithium metal batteries. A lithium battery pack consists of three parts: the cell, the protection board, and the casing. A lithium battery pack is assembled by adding a protection board or other battery accessories to one or more lithium cells. With the rapid expansion of the application fields of lithium-ion batteries, a large number of individual lithium batteries are connected in series and parallel to form lithium battery packs, which provide power for electric vehicles, energy storage power stations, communication base stations, and other systems. A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable batteries, lithium-ion batteries, and lithium-ion polymer batteries. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries were not used for a long time.

[0003] With the development of microelectronics technology at the end of the 20th century, miniaturized devices have become increasingly common, placing high demands on power supplies. Lithium-ion batteries subsequently entered a stage of large-scale practical application. Lithium-ion batteries possess advantages such as high voltage, large capacity, small size, light weight, and a wide operating temperature range. They have been widely used in various fields, including solar streetlights. Lithium-ion batteries operate by the movement of lithium ions between the positive and negative electrodes. During charging and discharging, lithium ions repeatedly insert and extract between the two electrodes, representing modern high-performance batteries that are energy-saving and environmentally friendly, leading to their widespread application.

[0004] The existing conductive connectors between overlapping modules can be divided into three types according to the connection method between the battery cell and the conductive busbar: welding, screwing, and mechanical crimping. In most cases, workers use bolts to fix the busbar to the sub-busbar of the battery module when connecting the wiring wires of the lithium battery pack. When there are many lithium battery packs, workers need to use bolts to connect the busbar and the sub-busbar one by one, which greatly increases the workload of workers and makes their work efficiency low. Summary of the Invention

[0005] The purpose of this invention is to provide a lithium battery pack with a quick-connection structure. By setting up a fixing component and a connecting component, it solves the problem that when workers use bolts to fix the busbars to the daughter busbars of the battery modules, the wiring wires of the lithium battery pack are fixed. When there are many lithium battery packs, workers need to use bolts to connect the busbars and daughter busbars one by one, which greatly increases the workload of workers and makes their work inefficient.

[0014] As a preferred technical solution of this application, slide rails are fixedly installed on both sides of the upper surface of the placement frame, and the sliding connectors on both sides are slidably connected to the inside of the slide rails.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In the scheme of this application:

[0019] 1. By setting up fixed and connecting components, operators can connect multiple lithium battery packs simultaneously, improving the device's ability to quickly connect lithium battery packs. During the connection process, the arc-shaped blocks on both sides slide downwards and slide inside the arc-shaped groove of the docking sleeve, causing the docking sleeve to rotate. The rotation of the docking sleeve opens the sealing baffles on both sides, releasing the elasticity of the elastic conductive sheet and allowing it to contact the lower surface of the conductive rod, thus energizing the device. When not in use, the sealing baffles on both sides seal the internal elastic conductive sheet inside the wire seat, preventing external water from contacting the elastic conductive sheet, increasing the safety of the device during conductive wiring, and solving the problem of low work efficiency caused by the operator's operation of connecting wires sequentially with bolts in the existing technology.

[0020] 2. By designing a sealing component, during wiring, the internal clamping plate, limited by the wire seat, drives the top column to compress the sealing airbag above through the compression ring. This causes the sealing airbag to contract under pressure, and the inner wall of the sealing airbag seals the connection between the conductive connector, the conductive rod, and the protective sleeve, preventing external dust from entering the wiring area. This avoids damage to the device due to dust and extends the service life of the lithium battery pack during wiring. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0041] Therefore, the following detailed description of embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figures 1 to 9. The present invention provides a technical solution: a lithium battery pack with a quick-connection structure, a placement frame 1, a closed door connected to one side surface of the placement frame 1 by a hinge, a support plate slidably connected inside the placement frame 1, a plurality of placement slots opened on the upper surface of the support plate, the lithium battery pack body 2 placed inside the placement slots, fixing components 3 fixedly installed on both sides of the upper surface of the placement frame 1, a horizontal plate 4 fixedly installed inside the fixing components 3, a connecting rod fixedly installed on the lower surface of the horizontal plate 4, an insulating sleeve fixedly installed on the lower surface of the connecting rod, a conductive connector 5 placed inside the insulating sleeve, a connecting component 6 fixedly installed on both sides of the lower surface of the conductive connector 5, a sealing component 7 fixedly installed inside the connecting component 6, a conductive wire 8 fixedly installed on the upper surface of the conductive connector 5, the conductive wire 8 passing through the interior of the horizontal plate 4, the connecting rod and the insulating sleeve, a conduit 9 fixedly installed on the upper surface of the horizontal plate 4, and an annular flexible block fixedly installed on the upper surface of the conduit 9.

[0043] The operator opens the closed door on one side of the placement frame 1, then pulls the support plate outward to place several lithium battery pack bodies 2 on the surface of the support plate. Then, the operator pushes the support plate inward to close the closed door, then presses down on the horizontal plate 4. The height of the horizontal plate 4 is then fixed by the fixing component 3, allowing the horizontal plate 4 to drive the connecting component 6 below for rapid wiring. At the same time, the internal sealing component 7 seals the connecting component 6, allowing the operator to simultaneously wire all the lithium battery pack bodies 2 inside the placement frame 1, greatly improving the wiring speed. At the same time, the fixing component 3 ensures that the device can stably maintain the state after wiring, preventing disconnection.

[0044] Example 2: The solution in Example 1 will be further described below with reference to the specific working method. As shown in Figures 1 to 9, as a preferred embodiment, based on the above method, the fixing component 3 further includes vertical rods fixedly installed at the four corners of the upper surface of the placement frame 1. A connecting plate 301 is slidably connected to one side surface of the vertical rod. Two connecting plates 301 are fixedly installed on both sides of the horizontal plate 4. A sliding rod 302 is rotatably connected to the lower surface of each of the two connecting plates 301. A sliding connector 303 is rotatably connected to the other end of the sliding rod 302. Slide rails 304 are fixedly installed on both sides of the upper surface of the placement frame 1. All connectors 303 are slidably connected to the inside of slide rail 304. Limiting grooves are provided on both sides of one side surface of slide rail 304. Connecting posts 305 are slidably connected inside the limiting grooves. One end of the connecting post 305 is fixedly installed on one side surface of the sliding connector 303. The same telescopic rod 306 is fixedly installed on one end of both connecting posts 305. A buckle is fixedly installed on the upper surface of telescopic rod 306. A limiting rod 307 is slidably connected inside the buckle. The limiting rod 307 slides through the surface of the outer rod of telescopic rod 306. Limiting grooves 308 are provided on both sides of the surface of the inner rod of telescopic rod 306. The limiting grooves 308 are adapted to the limiting rod 307.

[0045] The operator first pulls the limiting rods 307 on both sides upwards, causing one end of the limiting rod 307 to be pulled out of the limiting groove 308. By pressing the horizontal plate 4, the protective sleeve 601 is inserted into the docking sleeve 604. At the same time, the horizontal plate 4 drives the connecting plates 301 on both sides to slide downwards. The downward sliding of the connecting plates 301 causes the sliding connector 303 at one end of the sliding rod 302 to slide inside the slide rail 304. The sliding connector 303 causes the connecting post 305 to move. The connecting post 305 causes the telescopic rod 306 on one side to extend, so that the limiting rod 307, under the action of the return spring, is inserted into the limiting groove 308 on the other side of the telescopic rod 306, thus extending the telescopic rod. Rod 306 is in a fixed state, which allows the protective sleeve 601 to be stably connected to the docking sleeve 604. By pressing the horizontal plate 4, the conductive connector 5 below is driven to engage with the wiring connection on the upper part of the lithium battery pack body 2. Pressing the horizontal plate 4 can drive all the conductive connectors 5 below to quickly and synchronously wire all the lithium battery pack bodies 2, replacing the traditional manual wiring operation method, greatly improving the wiring efficiency, and avoiding the situation where the wiring cannot be successfully completed due to the negligence of the staff during wiring, and avoiding the situation of connection failure, so that the lithium battery pack body 2 can be stably and quickly wired and conductive.

[0046] Example 3: The following describes the solution in Example 2 in further detail with reference to the specific working method. As shown in Figures 1 to 9, as a preferred embodiment, based on the above method, the connecting component 6 further includes a protective sleeve 601 fixedly installed on both sides of the lower surface of the conductive connector 5. Arc-shaped blocks 602 are fixedly installed on both sides of the surface of the protective sleeve 601. Through holes are opened at both ends of the conductive connector 5. A conductive rod 603 is fixedly installed inside the through holes. A part of the conductive rod 603 is located inside the protective sleeve 601. A docking sleeve 604 is rotatably connected to the connection points on both sides of the upper surface of each lithium battery pack body 2. Arc-shaped grooves 605 are opened on both sides of the inner sidewall of the docking sleeve 604. 5. Adapted to the arc-shaped block 602, the mating sleeve 604 is provided with a wire seat 606 inside. The wire seat 606 has a groove inside, and an elastic conductive sheet 607 is placed inside the groove. Both sides of the upper surface of the wire seat 606 are rotatably connected to a sealing baffle 608. Both sides of the inner wall of the mating sleeve 604 are fixedly installed with a first ball joint. The surface of the first ball joint is fixedly connected to a diagonal rod 609. One end of the diagonal rod 609 is fixedly installed with a second ball joint. One end of the second ball joint is fixedly connected to a sliding column 610. The sliding column 610 slides through the inside of the wire seat 606. The other end of the sliding column 610 is rotatably connected to a pulling rod 611. One end of the pulling rod 611 is rotatably connected to the upper surface of the sealing baffle 608.

[0047] As the horizontal plate 4 moves downward, it drives the conductive connector 5 below to move as well. The conductive connector 5 drives the protective sleeve 601 below to insert into the inside of the docking sleeve 604. The arc-shaped blocks 602 on both sides of the protective sleeve 601 are inserted into the inside of the arc-shaped groove 605, so that the docking sleeve 604 rotates above the lithium battery pack body 2 under the action of the arc-shaped groove 605. During the rotation, the docking sleeve 604 drives the inclined rod 609 to move through the first ball joint. The inclined rod 609 drives the sliding column 610 to slide on the surface of the lead wire seat 606 through the second ball joint. The sliding column 610 slides and is opened by rotating the sealing baffle 608 at one end of the pulling rod 611. The elastic conductive sheet 607 has a certain degree of elasticity. After the sealing baffle 608 is rotated open, the elasticity of the elastic conductive sheet 607 causes it to pop outwards. The outwardly popped end always abuts against the bottom of the conductive rod 603. The top of the conductive rod 603 is connected to the conductive connector 5. The conductive connector 5 is connected to the conductive wire 8, so that the wiring of the device is in a working state. When the conductive rod 603 enters the wire seat 606, the sealing baffle 608 compresses the internal elastic conductive sheet 607 into the inside of the wire seat 606. When the elastic conductive sheet 607 is compressed inside, it is in a sealed state, and external debris cannot cause damage to the elastic conductive sheet 607. Interference, when disassembly is required, first contact the limiting position of the fixing component 3, then pull the horizontal plate 4 upward, causing the lower protective sleeve 601 to disengage from the interior of the docking sleeve 604. Under the action of the arc groove 605, the docking sleeve 604 rotates in the opposite direction to the initial position, thereby causing the internal sealing baffle 608 to move to the initial closed state, thus pressing the elastic conductive sheet 607 inside the wire seat 606 into the groove inside the wire seat 606, thereby disconnecting the electrical connection between the elastic conductive sheet 607 and the conductive rod 606. When the conductive rod 603 disengages from the interior of the wire seat 606, the sealing baffles 608 on both sides rotate in opposite directions, through the lower surface of the sealing baffle 608 One side is installed from the top of the elastic conductive sheet 607 downwards, causing the elastic conductive sheet 607 to retract into a sealed state and providing sealing protection for the elastic conductive sheet 607, thereby extending the life of the conductive connection of the elastic conductive sheet 607. At this time, the sealing baffle 608 prevents external dust or other substances from contacting the surface of the elastic conductive sheet 607, thereby avoiding the occurrence of poor wiring conductivity of the device, improving the conductivity of the device, and ensuring the safety of the device. When power cannot be supplied after wiring is completed, the operator can determine that the problem is caused by a fault in the elastic conductive sheet 607, reducing the occurrence of wiring problems in the device.

[0048] Example 4: The solution in Example 2 will be further described below with reference to the specific working method. As shown in Figures 1 to 9, as a preferred embodiment, based on the above method, the sealing component 7 further includes sealing grooves 701 formed on both sides of the inner wall of the protective sleeve 601. A fixing post 702 is fixedly installed inside the sealing groove 701. A clamping plate 703 is slidably connected to the surface of the fixing post 702. A top post is fixedly installed on the upper surface of the clamping plate 703. A compression ring 704 is fixedly installed on the upper surface of the top post. A sealing airbag 705 is fixedly installed on the upper surface of the compression ring 704. The sealing airbag 705 is fixedly installed on the inner wall of the protective sleeve 601. A conductive rod 603 is fixedly installed inside the sealing airbag 705. The sealing airbag 705 is fixedly installed at the connection between the protective sleeve 601 and the conductive connector 5.

[0049] As the protective sleeve 601 slides downwards, the sliding clamp 703 on the surface of the fixed post 702 abuts against the surface of the wire seat 606, causing the clamp 703 to slide upwards. The clamp 703 drives the compression ring 704 above the top post to move, causing the compression ring 704 to compress the sealing airbag 705 above. The compression force on the sealing airbag 705 causes its inner wall to press tightly against the gap between the conductive post 603, the protective sleeve 601, and the conductive connector 5, thus sealing the connection. After sealing, the connectivity of the device is improved, and the occurrence of damage to internal components is reduced, wiring costs are reduced, and the service life of each component is extended. At the same time, when the device vibrates, it can reduce the damage caused by vibration. After wiring is completed, it prevents external debris from entering the groove of the wire seat 606 through the gap, thereby affecting the conductive connection between the conductive rod 603 and the elastic conductive sheet 607, thus improving the stability of the conductive connection of the device.

[0050] Specifically, this quick-connection lithium battery pack operates / is used as follows:

[0051] The operator first pulls the limiting rods 307 on both sides upwards, causing one end of the limiting rod 307 to be pulled out of the limiting groove 308. By pressing the horizontal plate 4, the protective sleeve 601 is inserted into the docking sleeve 604. At the same time, the horizontal plate 4 causes the connecting plates 301 on both sides to slide downwards. The downward sliding of the connecting plates 301 causes the sliding connector 303 at one end of the sliding rod 302 to slide inside the slide rail 304. The sliding connector 303 causes the connecting post 305 to move. The connecting post 305 causes the telescopic rod 306 on one side to extend, so that the limiting rod 307 is inserted into the limiting groove 308 on the other side of the telescopic rod 306 under the action of the return spring, so that the telescopic rod 306 is fixed in a fixed state. As plate 4 moves downward, it drives the conductive connector 5 below to move as well. The conductive connector 5 drives the protective sleeve 601 below to insert into the docking sleeve 604. The arc-shaped blocks 602 on both sides of the protective sleeve 601 are inserted into the arc-shaped groove 605, causing the docking sleeve 604 to rotate above the lithium battery pack body 2 under the action of the arc-shaped groove 605. During the rotation, the docking sleeve 604 drives the inclined rod 609 to move through the first ball joint. The inclined rod 609 drives the sliding column 610 to slide on the surface of the lead seat 606 through the second ball joint. The sliding column 610 slides and is opened by rotating the sealing baffle 608 at one end of the pull rod 611. Due to the certain elastic conductive sheet 607 Due to the elasticity of the sealing baffle 608, after it is rotated open, the elastic conductive sheet 607 pops outward, with the outward end always contacting the bottom of the conductive rod 603. The top of the conductive rod 603 is connected to the conductive connector 5, and the surface of the conductive connector 5 is connected to the conductive wire 8, making the wiring of the device operational. As the protective sleeve 601 slides downward, the sliding clamp 703 on the surface of the fixed column 702 contacts the surface of the wire seat 606, causing the clamp 703 to slide upward. The clamp 703 drives the compression ring 704 above the top column to move, causing the compression ring 704 to compress the sealing airbag 705 above. The sealing airbag 705 is subjected to compression force. This allows the inner wall of the sealing airbag 705 to be tightly pressed against the gap between the conductive post 603, the protective sleeve 601, and the conductive connector 5, thus sealing the connection between the sealing airbag 705 and the connection. When disassembly is required, first, the fixing component 3 is contacted and limited, and then the horizontal plate 4 is pulled upward, causing the lower protective sleeve 601 to disengage from the inside of the docking sleeve 604. Under the action of the arc groove 605, the docking sleeve 604 rotates in the opposite direction to the initial position, thereby causing the internal sealing baffle 608 to move to the initial closed state, thereby pressing the elastic conductive sheet 607 inside the wire seat 606 into the groove inside the wire seat 606, thereby disconnecting the electrical connection between the elastic conductive sheet 607 and the conductive rod 606.

[0052] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above.
