Description
Technical Field
[0001] The utility model belongs to the technical field related to batteries, and particularly relates to a pouch battery with a strengthened shaping structure. Background Art
[0002] A pouch battery is a battery that uses a flexible plastic film as a packaging material. It is usually used in lithium-ion batteries and is widely used in fields such as electric vehicles and portable electronic devices due to its light weight, flexibility, and high energy density. The design of the pouch battery helps reduce the risk of internal short circuits and can be made into various shapes and sizes to meet different application requirements. However, it still has the following drawbacks in actual use:
[0003] After the pouch battery is produced, it needs to be installed in an electrical device. During the operation of the electrical device, when the battery is subjected to extrusion, twisting, etc., it will deform with the deformation of the electrical device. When the battery is repeatedly deformed, it is easy to cause damage to the internal structure, affecting the durability of the battery;
[0004] During the application of the pouch battery, when the battery is rapidly charged and discharged, heat is generated rapidly inside. The passive heat dissipation on the battery surface is not fast enough, and the battery gets hot. When the battery gets hot, the loss of its service life is accelerated, reducing the service life of the battery and shortening the replacement cycle of the battery. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a pouch battery with a strengthened shaping structure. By setting a battery body, a strengthening component, mounting ears, and a strengthening frame, the problems that the pouch battery is prone to deformation during use, resulting in damage to the internal structure, and that the heat generated during the use of the pouch battery causes a large loss to the service life are solved.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model is a pouch battery with a strengthened shaping structure, including a battery body, a strengthening component, mounting ears, and a strengthening frame. The battery body is fixed inside the strengthening component. The upper and lower parts of the outer peripheral surface of the battery body are both fixed with strengthening frames. Four corners of the mutually approaching surfaces of the two strengthening frames are all commonly fixed with support rods. Mounting ears are symmetrically fixed at the lower edges of both ends of the battery body. During operation, the battery body provides the charging and discharging function, the strengthening component increases the anti-twisting strength of the battery body, the mounting ears provide the installation function of the battery body in the electrical device, and the strengthening frame increases the strength of the edge of the battery body.
[0008] Further, the top surface of the upper reinforcing frame is lower than the top surface of the battery body, and the bottom surface of the lower reinforcing frame is higher than the bottom surface of the battery body. The reinforcing frame cooperates with the reinforcing component to maintain the shape of the battery body after plastic deformation.
[0009] Further, two electrodes are fixed at one end of the battery body, and the positions of the two electrodes are symmetric to each other. The battery body provides a circuit connection function with the electrical device through the electrodes.
[0010] Further, the reinforcing component includes a protection frame and reinforcing ribs. The protection frames are fixed on the outer surface of the battery body at equal intervals along its length direction. Reinforcing ribs are equally spaced and fixed on the top of the battery body between adjacent protection frames. Both ends of the reinforcing rib are respectively fixed on two protection frames. The reinforcing component protects the surface of the battery body through the protection frame and increases the anti-twisting strength of the battery body along the length direction through the cooperation of the reinforcing ribs.
[0011] Further, two ribbed bars II are fixed at both edge positions on the surface of the protection frame, and a ribbed bar I is fixed between the two ribbed bars II on the surface of the same protection frame. The protection frame increases its strength through the ribbed bar I and the ribbed bar II.
[0012] Further, the mounting ear is arranged below the lower reinforcing frame on the outer peripheral surface of the battery body. The end of the mounting ear away from the battery body is arc-shaped. A fixing rod is fixed at the arc-shaped position at the bottom of the mounting ear. The fixing rod is provided with a vertical jack along the central axis. The mounting ear is also vertically provided with the above-mentioned vertical jack. The vertical jack in the mounting ear corresponds to the vertical jack in the fixing rod. The mounting ear and the fixing rod are movably connected with a mounting screw through the vertical jack.
[0013] Further, three reinforcing plates are fixed at both short side edges at the bottom of the reinforcing frame. The reinforcing plates at both short sides at the bottom of the reinforcing frame are respectively fixed at both ends of the battery body. The distances between adjacent support rods at the same end of the battery body are equal. All the protection frames, ribbed bars I and ribbed bars II are fixed within the two reinforcing frames. The reinforcing frame increases the anti-deformation effect at the end of the battery body through the reinforcing plates.
[0014] The utility model has the following beneficial effects:
[0015] The utility model solves the problem that the pouch battery is prone to deformation during use, resulting in damage to the internal structure, by setting a battery body, a strengthening component and a strengthening frame. When the battery body works, the shape of the battery body along the length direction is determined by the first rib and the second rib on the protection frame, and the strength of the battery body against torsion along the length direction is assisted and enhanced by the first rib, the second rib and the auxiliary strengthening ribs on the surface of the protection frame, and the bending strength of the battery body against the direction parallel to the top surface of the battery body is increased by the strengthening frame, so as to better maintain the shape of the battery body and better prevent damage to the internal structure of the battery body.
[0016] The utility model solves the problem that the heat generated during the use of the pouch battery causes great loss to the service life by setting a battery body, a strengthening component, an installation ear and a strengthening frame. After the heat is generated on the battery body, the heat is transferred to the protection frame, the first rib, the second rib, the strengthening rib, the strengthening plate frame and the strengthening plate, and the passive heat dissipation of the battery body is greatly increased through the protection frame, the first rib, the second rib, the strengthening rib, the strengthening plate frame and the strengthening plate, so as to reduce the service life loss of the battery body due to heat generation during operation.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific Embodiment 1
[0028] Please refer to Figure 1-7 , the present invention is a bag-type battery with a strengthening and shaping structure, including a battery body 1, a reinforcement component 2, a mounting ear 3, and a reinforcing frame 4. The battery body 1 is fixed inside the reinforcement component 2. The reinforcement component 2 enhances the anti-twisting strength of the battery body 1 along the length direction. The battery body 1 performs charging and discharging operations. Reinforcing frames 4 are fixed to both the upper and lower parts of the outer peripheral surface of the battery body 1. The reinforcing frames 4 increase the strength of the battery body 1 against deformation in the horizontal direction. Support rods 401 are commonly fixed at the four corners of the mutually approaching sides of the two reinforcing frames 4. The support rods 401 increase the compressive strength of the battery body 1 in the vertical direction. Mounting ears 3 are symmetrically fixed to the lower edges at both ends of the battery body 1. The mounting ears 3 provide a mounting function between the battery body 1 and the electrical equipment.
[0029] Specifically, the top surface of the upper reinforcing frame 4 is lower than the top surface of the battery body 1, and the bottom surface of the lower reinforcing frame 4 is higher than the bottom surface of the battery body 1, so that the reinforcing frame 4 only strengthens the edge of the battery body 1.
[0030] Furthermore, two electrodes 101 are fixed to one end of the battery body 1. The positions of the two electrodes 101 are symmetrical to each other. The battery body 1 is electrically connected to the circuit of the electrical equipment through the electrodes 101.
[0031] Furthermore, the reinforcement component 2 includes a protection frame 201 and a reinforcing rib 202. The protection frame 201 is fixed to the outer surface of the battery body 1 at equal intervals along its length direction. Reinforcing ribs 202 are equally spaced and fixed to the top of the battery body 1 between adjacent protection frames 201. Both ends of the reinforcing rib 202 are respectively fixed to the two protection frames 201. The reinforcement component 2 connects the reinforcing rib 202 through the protection frame 201. The reinforcing rib 202 increases the anti-bending performance of the battery body 1.
[0032] Furthermore, rib reinforcements two 2012 are fixed at both edges of the surface of the protection frame 201. Between the two rib reinforcements two 2012 on the same surface of the protection frame 201, rib reinforcement one 2011 is fixed. The protection frame 201 cooperates with rib reinforcement one 2011 and rib reinforcement two 2012, and with the assistance and reinforcement of the reinforcing rib 202, the strength of the battery against torsional deformation along the length direction is increased.
[0033] The operation process of this embodiment is as follows: During operation, the charging and discharging function is provided by the battery main body 1. When the battery main body 1 is working, the shape of the battery main body 1 along the length direction is determined by rib reinforcement one 2011 and rib reinforcement two 2012 on the protection frame 201. The rib reinforcement one 2011 and rib reinforcement two 2012 on the surface of the protection frame 201 assist the reinforcing rib 202 to increase the strength of the battery main body 1 against torsion along the length direction, and the strengthening frame 4 increases the bending strength of the battery main body 1 against the direction parallel to the top surface of the battery main body 1. Specific Embodiment Two
[0034] Please refer to Figure 1 、 2 Figures 6 and 7. On the basis of Specific Embodiment One, the mounting ear 3 is arranged below the strengthening frame 4 on the outer peripheral surface of the battery main body 1 at the lower part. One end of the mounting ear 3 far from the battery main body 1 is arc-shaped. A fixing rod 301 is fixed at the position where the bottom of the mounting ear 3 is arc-shaped. The fixing rod 301 is vertically provided with a vertical jack 302 through its central axis. The mounting ear 3 is also vertically provided with the above-mentioned vertical jack 302. The vertical jack 302 in the mounting ear 3 corresponds to the position of the vertical jack 302 in the fixing rod 301. The mounting ear 3 and the fixing rod 301 are movably connected and installed with screws through the vertical jacks 302. The screws installed are inserted into the vertical jack 302 on the mounting ear 3, then inserted into the vertical jack 302 on the fixing rod 301, and then screwed into the mounting structure of the electrical device, so that the battery main body 1 is installed in the electrical structure and the bottom does not contact the electrical device.
[0035] Specifically, three reinforcing plates 402 are fixed at both short-edge edges of the bottom of the strengthening frame 4. The reinforcing plates 402 at both short sides of the bottom of the strengthening frame 4 are respectively fixed at both ends of the battery main body 1. The distances between the adjacent support rods 401 at the same end of the battery main body 1 are equal. All the protection frames 201, rib reinforcements one 2011 and rib reinforcements two 2012 are fixed within the two strengthening frames 4. The strengthening frame 4 increases the compressive strength at the ends of the battery main body 1 through the reinforcing plates 402 and the support rods 401. At the same time, through the arrangement of the strengthening frame 4, the support rods 401 and the reinforcing plates 402, the shape of the battery main body 1 is maintained.
[0036] The operation process of this embodiment is as follows: during operation, the screw installed is inserted into the vertical jack 302 on the mounting ear 3, and then into the vertical jack 302 on the fixing rod 301, and then screwed into the mounting structure of the electrical device, so that the battery body 1 is well installed in the electrical structure and does not contact the electrical device at the bottom. After heat is generated on the battery body 1, the heat is transferred to the protection frame 201, the first rib 2011, the second rib 2012, the reinforcing rib 202, the frame of the reinforcing plate 402 and the reinforcing plate 402. Through the protection frame 201, the first rib 2011, the second rib 2012, the reinforcing rib 202, the frame of the reinforcing plate 402 and the reinforcing plate 402, the passive heat dissipation of the battery body 1 is greatly increased, and the service life of the battery body 1 consumed due to heat generation during operation is reduced.
