Description

Technical Field

[0001] The invention relates to the field of battery wiring, in particular to a battery capable of rapid wiring. Background Art

[0002] Batteries, as energy storage and power supply devices, are widely used in automobiles, power tools, energy storage systems, and uninterruptible power supplies (UPS). Traditional battery wiring methods usually use bolt fixing, clamping connection or welding. These connection methods have certain limitations. For example, the bolt fixing method requires the use of tools for disassembly and assembly, which is cumbersome to operate. After long-term use, the bolts may become loose due to vibration, affecting the stability of power transmission. Although the clamping connection improves the disassembly and assembly efficiency, it may cause poor contact under high current loads or long-term use. In addition, although the welding connection method is reliable, it is not removable and is not suitable for scenarios where frequent battery replacement is required.

[0003] With the diversification of battery application requirements, especially in electric vehicles, renewable energy storage systems and portable power devices, users have put forward higher requirements for the installation and replacement efficiency of batteries. Therefore, the development of a battery connection method that can quickly, safely and reliably connect batteries has important practical value and market prospects.

[0004] After searching, it was found that the prior art publication number is CN115693274A, which discloses a battery terminal connector device and a connector method, including a conductive connector body for installing a conductive threaded sleeve and a quick plug; a conductive threaded sleeve for connecting the terminal; the conductive threaded sleeve is sleeved on the terminal and can be detachably installed on the conductive connector body; a quick plug for connecting the conductive connector body and the battery connection line; the quick plug is connected to the conductive connector body and the battery connection line, and can be detachably installed on the conductive connector body. The scheme provides a battery terminal connector device and a connector method, which adopts the method of screwing the internal thread of the conductive threaded sleeve into the battery terminal to firmly fasten the battery terminal; at the same time, the battery connection line is firmly connected to the conductive connector body through the quick plug, replacing the original bolt and nut connection method, which can effectively prevent loosening and false connection between the battery terminal connector and the battery connection line. It is easy to operate, fast to install, and improves work efficiency.

[0005] Therefore, based on the above search and in combination with existing technologies, the existing battery terminal connector device and connector method cannot automatically cut off the power to deal with the fire risk caused by a circuit short circuit, is insufficient in safety, and has low application prospects and practical value.

[0039] 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.

[0040] Example 1: Please refer to Figures 1 to 6 A battery with quick wiring includes a battery body 1, with two mounting components 2 respectively installed on the left and right ends of the top surface of the battery body 1. Specifically, two mounting openings 11 are symmetrically opened on the top surface of the battery body 1, and the positive and negative electrodes of the battery body 1 are fixedly installed on the bottom surfaces of the two mounting openings 11 respectively. The mounting component 2 includes a mounting cylinder 21, and a downward pressure rebound component 3 is installed on the inner wall of the mounting cylinder 21. The bottom surface of the downward pressure rebound component 3 is installed with a power connection component 4. The power connection component 4 is electrically connected to the electrodes of the battery body 1 under the action of the downward pressure rebound component 3. A fuse component 5 is installed on the top surface of the downward pressure rebound component 3, and a wiring component 6 is fixedly installed on the top surface of the fuse component 5.

[0041] The downward-pressing rebound component 3 includes a fixed cylinder 31, which is fixedly mounted on the inner wall of the mounting cylinder 21. The inner wall of the fixed cylinder 31 is slidably connected to the sliding cylinder 32. Specifically, a plurality of sliding grooves 311 are equidistantly provided on the inner wall of the fixed cylinder 31. A plurality of ridges 321 are equidistantly provided on the outer wall of the sliding cylinder 32. The number of ridges 321 is equal to the number of sliding grooves 311. The ridges 321 are slidably connected to the sliding grooves 311 respectively. The sliding grooves 311 have a limiting and guiding effect on the ridges 321, so that the sliding cylinder 32 cannot rotate when sliding up and down in the fixed cylinder 31. The inner wall of the sliding cylinder 32 is slidably connected to the sliding cylinder 32. The driven rod 33 has four card strips 332 equidistantly arranged on the outer wall of the bottom end of the driven rod 33, and the outer wall of the fixed cylinder 31 is provided with four limiting slide rails 312. The four card strips 332 are slidably connected to the four limiting slide rails 312 respectively. Specifically, the inner wall size of the limiting slide rail 312 is adapted to the outer wall size of the card strip 332. The limiting slide rail 312 has a limiting guiding effect on the card strip 332, so that the driven rod 33 cannot rotate. The bottom surface of the fixed cylinder 31 is equidistantly provided with eight first inclined surfaces 313, and the bottom surface of the sliding cylinder 32 is equidistantly provided with eight groups of second inclined surfaces 322. The tops of the four card strips 332 are provided with The third inclined surface 333 is in sliding contact with the second inclined surface 322. Specifically, the inclination angles of the first inclined surface 313, the second inclined surface 322 and the third inclined surface 333 are equal. Each group of second inclined surfaces 322 is composed of two mutually symmetrical second inclined surfaces 322. The second inclined surface 322 and the third inclined surface 333 are equal in length. The length of the first inclined surface 313 is twice the length of the third inclined surface 333. When the clamping strip 332 is slidably clamped in the limiting slide rail 312, only half of the area of ​​the second inclined surface 322 and the third inclined surface 333 are in contact. The second inclined surface 322 is the same as the second inclined surface 333. 322 has a driving force for the third inclined surface 333 to rotate, but the snap-in strip 332 is restricted by the limiting slide rail 312, and the driven rod 33 cannot rotate. When the sliding cylinder 32 drives the driven rod 33 to move downward, the snap-in strip 332 disengages from the limiting slide rail 312, and the second inclined surface 322 releases the driving force on the third inclined surface 333, causing the driven rod 33 to rotate, and the third inclined surface 333 disengages from the sliding contact with the second inclined surface 322 and slides into contact with the first inclined surface 313 until the top end of the snap-in strip 332 is fixedly abutted against the top end of the first inclined surface 313, thereby changing the position of the driven rod 33 and fixing it.

[0042] Example 2: Please refer to Figures 1 to 7 、 Figure 10 、 Figure 11A battery with quick wiring is different from Example 1 in that the power connection component 4 includes a mounting plate 41, and a slide bar 411 is provided at both ends of the mounting plate 41. The two slide bars 411 are respectively slidably inserted into the bottom end of the driven rod 33. Specifically, the bottom surface of the driven rod 33 is symmetrically provided with two insertion grooves, and the two slide bars 411 are respectively slidably inserted into the two insertion grooves. A spring 43 is sandwiched between the top surface of the mounting plate 41 and the bottom surface of the driven rod 33. A contact electrode 42 is installed at the center of the bottom surface of the mounting plate 41. For details, please refer to Figure 11 The top surface of the contact electrode 42 is soldered to a wire, and the wire extends through the hole opened at the center of the top surface of the mounting plate 41 and extends into the wiring groove 334 inside the driven rod 33. A mounting ring 331 is provided at the bottom end of the outer wall of the driven rod 33, and a spring 2 44 is rotatably installed at the bottom end of the mounting ring 331. Specifically, a rotation groove is provided on the bottom surface of the mounting ring 331, and the top end of the spring 2 44 is slidably installed in the rotation groove, and the top end of the spring 2 44 can rotate in the rotation groove. The end of the spring 2 44 away from the mounting ring 331 is fixedly installed on the inner bottom surface of the mounting cylinder 21. Specifically, a connecting hole 214 is provided at the center of the bottom surface of the mounting cylinder 21, and the electrode of the battery body 1 extends into the interior of the mounting cylinder 21 after passing through the connecting hole 214. By pressing down the driven rod 33 to compress the spring 1 43 and the spring 2 44, the contact electrode 42 can be electrically connected to the electrode of the battery body 1.

[0043] Example 3: Please refer to Figures 5 to 12, a battery with quick wiring, which differs from Example 1 in that the insurance component 5 includes a storage box 51, specifically, the storage box 51 stores expansion oil, and an annular oil cylinder 511 is extended from the bottom surface of the storage box 51, and an annular piston 52 is slidably installed on the top of the inner wall of the annular oil cylinder 511. Specifically, the outer wall size of the annular piston 52 is adapted to the inner wall size of the annular oil cylinder 511, and the inner and outer walls of the annular piston 52 are both installed with sealing rings 521, which are used to enhance the sealing between the annular piston 52 and the annular oil cylinder 511. The annular oil cylinder 511 and the storage box 51 are both made of aluminum oxide, which has the advantages of moderate thermal conductivity, high melting point, and good insulation. The annular oil cylinder 511 is connected to the internal space of the storage box 51, and the capacity of the annular oil cylinder 511 is approximately one-fifth of the capacity of the storage box 51. According to the physical properties of the expansion oil, the volume of the expansion oil will expand at high temperatures. For every 1°C increase in temperature, the volume of the expansion oil will increase by about 0.07% to 0.1%. After calculation, at 300°C, the volume of the expansion oil will usually expand by about 20% to 25%. A support ring 522 is provided on the bottom surface of the annular piston 52. The support ring 522 is equal to the height of the annular cylinder 511. Specifically, a blocking ring is provided at the bottom end of the annular cylinder 511.

A mounting hole 512 that passes through the top and bottom is provided at the center of the top surface of the storage box 51. The connecting cylinder 53 is fixedly connected to the inner thread of the mounting hole 512.

[0044] See also Figure 8 、 Figure 9The wiring assembly 6 includes a power copper post 61, which is fixedly installed in the connecting tube 53. Specifically, the connecting tube 53 and the power copper post 61 are made of copper. Copper has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. The melting point of copper is 1085°C. The bottom end of the power copper post 61 is soldered to the wire in the connection groove 334. The contact electrode 42 is connected to the power copper post 61 through a wire. The wire has a certain margin in the connection groove 334 to prevent the wire from being pulled and falling off. The outer wall of the power copper post 61 is slidably connected to a plurality of clamping plates 62. A spring 63 is clamped between each of the plurality of clamping plates 62. Specifically, the clamping plate 62 is made of copper. The clamping disk 62 is electrically connected to the power copper column 61. Several clamping disks 62 are used to clamp external wires. Several protrusions are provided on both the top and bottom surfaces of the clamping disk 62.

[0045] See also Figure 5 、 Figures 9 to 12 , two support frames 211 are symmetrically provided on the top surface of the installation cylinder 21, and the ends of the two support frames 211 are connected to the outer wall of the clamping plate 62 at the bottom. Specifically, the ends of the two support frames 211 are respectively fixedly connected to the outer wall of the clamping plate 62 at the bottom. Specifically, the ends of the two support frames 211 are provided with pulleys 22, and the outer walls of the two elastic ropes 23 are respectively in contact with the outer walls of the two pulleys 22. The pulleys 22 have a guiding function and can reduce the wear of the elastic ropes 23 and extend the service life of the elastic ropes 23. The material of the elastic ropes 23 is natural rubber or synthetic rubber, which has a softening temperature of about 60°C to 80°C and a decomposition temperature of about 200°C to 300°C. The top surface of the installation cylinder 21 is symmetrically provided with two support frames 211. A fixing frame 212 is provided, and the outer walls of the two fixing frames 212 are both provided with a through L-shaped rail 213. The outer wall of the pressing plate 65 is provided with two fixing blocks 651. The outer wall size of the fixing block 651 is adapted to the inner wall size of the L-shaped rail 213. Specifically, by pressing down the pressing plate 65, the two fixing blocks 651 are respectively entered into the two L-shaped rails 213. The top surface of the pressing plate 65 is provided with a torsion plate 652. The rotating disk 64 is rotated by the torsion plate 652 to fix the fixing block 651 in the L-shaped rail 213, thereby fixing the pressing plate 65. During this process, the two elastic ropes 23 pull the clamping plate 62 at the bottom to slide upward on the outer wall of the power-connecting copper column 61, compressing the spring three 63, so that the multiple clamping plates 62 are close to each other.

[0046] The working principle of the present invention is as follows: when the device is in use, the external wire is first wound around the outer wall of the power copper column 61. When the battery body 1 needs to connect multiple wires, it should be noted that the multiple external wires are required to be connected in phase and installed on the outer wall of the power copper column 61. A plurality of clamping plates 62 are used to clamp the external wires between each other. The clamping plates 62 are made of copper and are electrically connected to the power copper column 61. After the winding of the external wires is completed, the pressing plate 65 is pushed downward. During this process, the two elastic ropes 23 pull the clamping plate 62 at the bottom end to slide upward on the outer wall of the power copper column 61 to compress the spring three 63, so that the clamping plates 62 are close to each other until the external wires are clamped and fixed between each other. A plurality of protrusions are provided on both the top and bottom surfaces of the clamping plates 62. The protrusions are used to enhance the friction between the clamping plates 62 and the external wires, thereby enhancing the stability of the clamping connection.

[0047] When the pressing plate 65 moves downward, the pressing plate 65 drives the safety assembly 5 to move downward through the electrical copper column 61, and the safety assembly 5 drives the sliding cylinder 32 to slide downward in the fixed cylinder 31, and the sliding cylinder 32 drives the driven rod 33 to move downward, and the driven rod 33 compresses the spring 2 44 and the spring 1 43, so that the contact electrode 42 is electrically connected to the electrode of the battery body 1. At this time, the clamping strip 332 slides and is clamped in the limiting slide rail 312, and the second inclined surface 322 and the third inclined surface 333 are only half in contact with each other. The second inclined surface 322 has a driving force for rotating the third inclined surface 333, but the clamping strip 332 is restricted by the limiting slide rail 312, and the driven rod 33 cannot rotate. When the sliding cylinder 32 continues to drive the driven rod 33 to move downward, the clamping strip 332 is separated from the limiting slide rail 312, and the second inclined surface 322 releases the driving force on the third inclined surface 333, causing the driven rod 33 to rotate. The third inclined surface 333 is disengaged from the sliding contact with the second inclined surface 322 and slides into contact with the first inclined surface 313 until the top of the clamping strip 332 is fixedly abutted against the top of the first inclined surface 313, thereby changing the height of the driven rod 33 and fixing it. At this time, the spring 1 43 and the spring 2 44 are both compressed and transmit upward elastic force to the driven rod 33, and the rotating disk 64 is rotated by the torsion plate 652 to make the two fixing blocks 651 enter the two L-shaped rails 213 respectively. Since the pressing plate 65 is also subjected to the upward pulling force of the two elastic ropes 23, the two fixing blocks 651 are moved upward and fixed in the L-shaped rails 213, thereby fixing the pressing plate 65. At this time, the contact electrode 42 is electrically connected to the electrode of the battery body 1, and the contact electrode 42 is connected to the electrical copper column 61 through a wire, thereby electrically connecting the external wire to the electrode of the battery body 1, thereby realizing quick wiring of the external wire.

[0048] When the external circuit at the wiring assembly 6 is short-circuited, the temperature range during a short circuit is typically 300°C to 1000°C. If the conductor temperature exceeds 1000°C, a fire may occur. The present device is equipped with an automatic power-off protection measure. First, the elastic cord 23 is made of natural or synthetic rubber, which has a softening temperature of approximately 60°C to 80°C and a decomposition temperature of approximately 200°C to 300°C. The clamping disk 62 is made of copper, which has excellent thermal conductivity. When the temperature of the clamping disk 62 exceeds 300°C, the two elastic cords 23 connected to the clamping disk 62 will directly melt, and the plurality of springs 63 will release their elastic force to separate the plurality of clamping disks 62 and cancel the clamping of the external conductor, thereby performing a preliminary power-off operation.

[0049] If the initial power-off is unsuccessful, the temperature of the copper post 61 will continue to rise. The connecting tube 53 and the copper post 61 are both made of copper. Copper has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. The melting point of copper is 1085°C. The connecting tube 53 transmits the temperature of the copper post 61 to the storage box 51. The annular oil cylinder 511 and the storage box 51 are both made of alumina. Alumina has the advantages of moderate thermal conductivity, high melting point and good insulation. The expansion oil in the storage box 51 absorbs heat and expands. The annular oil cylinder 51 The capacity of the expansion oil is about one-fifth of the capacity of the storage tank 51. According to the physical properties of the expansion oil, the volume of the expansion oil will expand at high temperatures. For every 1°C increase in temperature, the volume of the expansion oil will increase by about 0.07% to 0.1%. According to calculations, at 300°C, the volume of the expansion oil will usually expand by about 20% to 25%. The expansion of the expansion oil pushes the annular piston 52 to move downward in the annular cylinder 511. The annular piston 52 pushes the sliding cylinder 32 downward through the support ring 522, and the sliding cylinder 32 drives the driven The rod 33 moves downward, compressing the spring 1 43 and the spring 2 44. At this time, only half of the area of ​​the second inclined surface 322 and the third inclined surface 333 abuts. The second inclined surface 322 has a driving force to rotate the third inclined surface 333. However, the third inclined surface 333 of the clamping strip 332 is restricted by the vertical surface on the side of the first inclined surface 313, and the driven rod 33 cannot rotate. When the sliding cylinder 32 continues to drive the driven rod 33 to move downward, the clamping strip 332 is freed from the vertical surface restriction on the side of the first inclined surface 313. The second inclined surface 322 releases the driving force on the third inclined surface 333, causing the driven rod 33 to rotate. The third inclined surface 333 breaks away from the sliding contact with the second inclined surface 322 and slides into the limiting slide rail 312. The spring 2 44 releases the elastic force and continues to lift the driven rod 33 until the contact electrode 42 breaks away from the electrode of the battery body 1. In this way, the power-off operation is completed, and the electrical connection between the external wire and the battery body 1 is disconnected, thereby preventing the temperature from continuing to rise and causing a fire.
