Description

Technical Field

[0001] The invention belongs to the technical field of batteries, and in particular relates to a lithium battery with strong impact resistance. Background Art

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have now become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The safety, specific capacity, self-discharge rate, and performance-price ratio of rechargeable batteries are better than those of lithium-ion batteries. Lithium batteries are generally used in electric vehicles or new energy vehicles.

[0003] During the use of current lithium batteries, a protective box is installed on the outside. However, during the use of lithium batteries, there is a possibility of being damaged by bumps and collisions, causing damage to the lithium batteries inside. This will lead to dangerous situations. There is no good anti-collision processing ability, so a lithium battery with strong impact resistance is proposed. Summary of the invention

[0006] By adopting the above technical solution, a compensation unit is installed in the compensation box. When the compensation box is bumped, the bump transferred to the lithium battery is weakened by the compensation unit, so that the lithium battery can be more secure.

[0007] Furthermore, the compensation unit includes a compensation part, the compression plate is arranged at a distance from the inner wall of the compensation box, the compensation part is arranged between the compression plate and the inner wall of the compensation box to connect the compression plate and the compensation box, the compensation part is used to drive the compression plate to be connected to the top contact of the lithium battery, and a polyurethane layer is arranged on the side of the compression plate closer to the lithium battery to offset and weaken the impact force released on the lithium battery.

[0008] By adopting the above technical solution, when the compensation box encounters a bump, the compensation box is displaced based on the lithium battery, and the compensation part is lengthened or shortened to offset the bump and reduce the damage to the lithium battery.

[0010] By adopting the above technical solution, during the period when the compensation box is placed on the side of the lithium battery, the rotating column is rotated, and the rotating column pulls and drives the winding disk to rotate. The winding disk rotates to wind the connecting wire body around the winding disk, and the connecting wire body drives the linkage rod to move, thereby changing the orientation of the compression plate, so that the distance between the compression plate and the lithium battery is increased during the assembly of the compensation box.

[0011] Furthermore, a storage cavity is reserved in the side outer edge area of ​​the compensation box, and the storage cavity is arranged adjacent to the rotating column at the end farther from the winding disk.

[0016] By adopting the above technical solution, when the connecting wire pulls the pressure plate to move, the pressure plate is driven to rotate, so that the pressure plate is in an angle shape, and the distance between the side of the pressure plate closer to the base and the lithium battery is increased, which is conducive to placing the compensation box and the pressure plate on the side of the lithium battery.

[0021] Furthermore, a pressing piece is arranged on one end of the driving column close to the screw connection of the driving column.

[0022] By adopting the above technical solution and installing a pressing piece, when the orientation of the rotating column needs to be changed by the driving column, one end of the driving column can be swung open by squeezing the pressing piece, which is beneficial to subsequent actions.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1-7 An embodiment of the present invention provides a lithium battery with strong impact resistance, including a lithium battery 12 mounted on a base 112, a compensation box 13 is mounted around the lithium battery 12, there is a distance between the compensation box 13 and the lithium battery 12, a compensation unit 14 is mounted on the compensation box 13, the compensation box 13 is connected to the lithium battery 12 via the compensation unit 14, and the lithium battery 12 is protected by the compensation box 13 and the compensation unit 14 when it is subjected to surrounding collisions.

[0039] The compensation box 13 is a square structure, and the side of the compensation box 13 closer to the base 112 is open and installed. The compensation box 13 is installed on the lithium battery 12 through the open part. A plurality of compensation units 14 are installed, and each of the plurality of compensation units 14 is adapted and installed with a plurality of inner walls of the compensation box 13. The compensation unit 14 includes a compression sheet 142 and a compensation part 143. The compensation part 143 can be made of a spiral beryllium copper wire. One end of the spiral beryllium copper wire is connected to the inner wall of the compensation box 13, and the other end of the spiral beryllium copper wire is connected to the compression sheet 142. There is a distance between the compression sheet 142 and the inner wall of the compensation box 13, and the end of the compression sheet 142 farther from the compensation part 143 is connected to the wall of the lithium battery 12 in contact with the top. In the initial stage, the spiral beryllium copper wire is in a compressed and shortened state, and the compression plate 142 contacts the wall of the lithium battery 12 due to the spiral beryllium copper wire. During the period of collision around the load, a compression impulse is generated and released on the compensation box 13. The compensation box 13 moves due to the collision, and through the change of the spiral beryllium copper wire, the force transferred to the lithium battery 12 is weakened, and the impulse borne by the lithium battery 12 is weakened, so that the lithium battery 12 is protected.

[0040] A polyurethane layer is disposed on the side of the compression sheet 142 closer to the lithium battery 12 , and the compression sheet 142 is connected to the lithium battery 12 via the polyurethane layer, which can further weaken the force transmitted to the lithium battery 12 during collision. The compression sheet 142 is arranged in a direction and at a distance from the inner wall of the adjacent compensation box 13. A linkage rod 15 is arranged on the compression sheet 142, and the linkage rod 15 is arranged at a 90-degree angle to the compression sheet 142. A displacement groove 132 is reserved on the compensation box 13. The end of the linkage rod 15 farther from the compression sheet 142 extends into the displacement groove 132, and is slidably arranged in the displacement groove 132 along the direction of 90 degrees to the compression sheet 142. A fixing piece 153 is reserved on the linkage rod 15. A spiral beryllium copper wire is arranged on the side of the linkage rod 15. One end of the spiral beryllium copper wire is connected to the inner wall of the compensation box 13, and the other end of the spiral beryllium copper wire is connected to the fixing piece 153. A placement cavity 133 is reserved in the compensation box 13, and a change unit 16 for changing the orientation of the linkage rod 15 is arranged in the placement cavity 133. The position of the linkage rod 15 is changed by the changing unit 16, thereby changing the position of the compression plate 142, so that the span between the compression plate 142 and the lithium battery 12 becomes larger, which is conducive to installing the compensation box 13 and the compression plate 142 on the side of the lithium battery 12.

[0041] The side of the offset box 13 that is farther from the base 112 is the upper part, and the other side walls are the side parts. The changing unit 16 includes a connecting wire body 162, a winding disk 163 and a rotating column 164. The winding disk 163 is arranged in the central area close to the upper part and is rotatingly arranged in the placement chamber 133. The rotation center line of the winding disk 163 is arranged at 90 degrees to the upper part. One end of the connecting wire body 162 is connected to the end of the linkage rod 15 that is farther from the compression plate 142. The other end of the connecting wire body 162 extends to the upper part through the placement chamber 133 and is connected to the winding disk 163. One end of the rotating column 164 is connected to the head of the winding disk 163. The other end of the rotating column 164 is arranged in a direction farther from the winding disk 163, and the winding disk 163 can be rotated by rotating the rotating column 164, so that the connecting wire body 162 is wound on the winding disk 163, and the connecting wire body 162 drives the linkage rod 15 to move, and the linkage rod 15 moves to drive the pressing piece 142 to move in the direction toward the inner wall of the compensation box 13, so that during the placement of the compensation box 13, the pressing piece 142 is placed on the side of the lithium battery 12, and then the rotating column 164 can be released, and the pressing piece 142 is restored to the original position due to the compensation part 143 to constrain the compensation box 13. A wire reel is arranged in the corner area of ​​the connecting wire body 162, and the installation position of the connecting wire body 162 in the placement cavity 133 is changed through the wire reel, so as to reduce the contact resistance between the connecting wire body 162 and the inner wall of the placement cavity 133.

[0042] The ends of the connecting wires 162 that are farther from the linkage rod 15 are connected to the winding drum 163, and the connecting wires 162 are connected to the linkage rod 15 in the side wall. The areas where the connecting wires 162 are connected on the winding drum 163 are arranged at the same distance. During the rotation of the winding drum 163, the connecting wires 162 are surrounded together on the winding drum 163, thereby changing the orientations of the compression plates 142 together.

[0043] In order to facilitate the rotation of the rotating column 164, a storage chamber 134 is reserved in the side outer edge area of ​​the offset box 13, the storage chamber 134 is communicated with the placement chamber 133, the storage chamber 134 is arranged adjacent to the rotating column 164 at the end farther from the winding disk 163, the driving column 17 is rotatably arranged in the storage chamber 134, one end of the driving column 17 is rotatably arranged in the storage chamber 134, a driving bar 1342 is arranged at the end of the storage chamber 134 closer to the driving column 17, a driving wire body 172 is arranged in the storage chamber 134 and the placement chamber 133, one end of the driving wire body 172 is connected to the end of the rotating column 164 farther from the winding disk 163, and the other end of the driving wire body 172 is connected to one end of the driving column 17 via the driving bar 1342. In the initial stage, the compression piece 142 contacts the surface wall of the lithium battery 12, and the driving column 17 contacts the inner wall of the storage chamber 134. When the position of the compression piece 142 needs to be changed, the driving column 17 is rotated, and the driving column 17 drives the rotating column 164 to rotate through the driving line 172, thereby changing the position of the compression piece 142. A compression member 173 is installed on the driving column 17. By driving the compression member 173 into the storage chamber 134, the end of the driving column 17 farther from the rotating position can be swung open, which is conducive to rotating the driving column 17.

[0044] The side of the compensation box 13 that is closer to the base 112 is installed at a distance from the base 112, and the side of the lithium battery 12 that is closer to the base 112 is installed with a blocking piece 120. The blocking piece 120 is slidably installed on the outside of the lithium battery 12, and the side of the blocking piece 120 that is farther from the compensation box 13 is in contact with the base 112.

[0045] The end of the linkage rod 15 closer to the compression plate 142 is screwed to the rotating bead 152, and the linkage rod 15 is connected to the compression plate 142 via the rotating bead 152. A compression ring 18 is installed on the side of the compression plate 142 closer to the linkage rod 15. A plurality of correcting parts 182 are installed on the side wall of the linkage rod 15. The correcting parts 182 are spiral beryllium copper wires, one end of the spiral beryllium copper wire is connected to the linkage rod 15, and the other end of the spiral beryllium copper wire is connected to the compression ring 18. A plurality of spiral beryllium copper wires are installed around the linkage rod 15 at the same distance, that is, a plurality of spiral beryllium copper wires and the linkage rod 15 are installed at ninety degrees. By installing a plurality of spiral beryllium copper wires and rotating beads 152, when the upper side of the compensation box 13 is hit by the base 112, the offset part 143 installed on the upper part is tightened and shortened, which can offset and weaken the hit. The side linkage rod 15 is displaced based on the compression plate 142 due to the rotating beads 152. When hit in any direction, the linkage rods 15 close to each other can be displaced based on the compression plate 142, which reduces the situation where the side linkage rods 15 and the compression plate 142 hinder the displacement of the compensation box 13, and makes the offset collision action more stable.

[0046] The central area of ​​the compression ring 18 and the central area of ​​the compression plate 142 are overlapped, that is, in the initial stage, a number of spiral beryllium copper wires are arranged around the compression plate 142 and the central area of ​​the driving column 17 at the same distance, the rotating bead 152 is adapted to be arranged in the central area of ​​the compression plate 142, and one end of the connecting wire 162 connected to the compression plate 142 is arranged on the side of the compression ring 18 farther from the linkage rod 15, and the connection between the connecting wire 162 and the compression plate 142 is arranged between the compression ring 18 and the base 112. When the orientation of the compression plate 142 is changed by the connecting wire 162, because the connecting wire 162 is at the force-generating point of the compression plate 142, that is, the driving point is not in the central area of ​​the compression plate 142, during the displacement of the compression plate 142, the side of the compression plate 142 closer to the base 112 can be driven to be installed at an angle along the side farther from the lithium battery 12, thereby making the distance between the side compression plate 142 and the lithium battery 12 larger from the side of the base 112, which is beneficial for installing the compensation box 13 on the surrounding side of the lithium battery 12 during assembly.

[0047] A swing module 19 is installed on the side of the pressure plate 142 closer to the base 112. The swing module 19 is rotatably installed on the pressure plate 142. A return member 192 is installed on the pin of the swing module 19. A spiral beryllium copper wire X is installed on the return member 192. The spiral beryllium copper wire X can generate opposite torsion when the rotational deformation is restored. One end of the spiral beryllium copper wire X is connected to the pressure plate 142, and the other end of the pressure plate 142 is connected to the pin of the swing module 19. One end of the connecting wire body 162 is connected to the side of the swing module 19 farther from the lithium battery 12. A constraint piece 193 is installed on the swing module 19, and a constraint piece 194 is installed on the pressure piece 142. The constraint piece 193 and the constraint piece 194 are respectively installed on both sides of the swing module 19, and the constraint piece 194 is installed on the pressure piece 142 at a position closer to the swing module 19. When the swing module 19 rotates to various positions, it is connected with the pressure piece 142. In the initial stage, the constraint piece 193 is connected with the pressure piece 142, and the swing module 19 and the pressure piece 142 are on the same plane. When the swing module 19 rotates a specific angle, the constraint piece 194 is connected with the swing module 19. During the period when the connecting wire body 162 drives the compression plate 142 to rotate, the swing module 19 is first driven to rotate until the constraint plate 2 194 is in contact with the swing module 19 and connected, and then the connecting wire body 162 is driven to drive the compression plate 142 to rotate and change the position of the compression plate 142. During the period when the connecting wire body 162 is driven, the swing module 19 is driven to rotate. After the rotation, the swing module 19 forms a guide wall, which can facilitate the installation of the compensation box 13 on the surrounding side of the lithium battery 12.

[0048] The specific implementation method is as follows: by installing a compression plate 142 and a compensation part 143 in the compensation box 13, when it is hit by the surroundings, the collision is released on the compensation box 13, and the compensation part 143 in each area becomes longer or shorter during the displacement of the compensation box 13, thereby offsetting and weakening the collision released on the lithium battery 12, weakening the damage to the lithium battery 12, protecting the lithium battery 12, and reducing the probability of dangerous situations.
