Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a vibration-resistant battery and a battery tank. Background Art

[0002] Commercial vehicle batteries are used in harsh environments. The batteries themselves are heavy. During vehicle driving, bumpy road conditions will cause certain vibrations in the battery compartment. The battery will experience certain accelerations in all directions on the vehicle. This will cause internal connectors to shake and displace, which in turn will lead to failure modes such as broken plate ears, broken grid bars, and busbars, reducing the battery's service life. In order to improve the battery's vibration resistance, hot melt glue is usually added to the bottom of the battery slot to fix the pole group. At the same time, in order to improve the tight assembly of the pole group, a liner will be used to wrap the pole group for insertion into the slot. In order to save production costs, hot melt adhesive is generally only applied in a layer at the bottom of the tank body, while the existing lining is designed with a connecting strip at the bottom. After the pole group enters the tank, the lining strip has a thickness. After the connecting strip contacts the bottom of the tank, the pole group is lifted, resulting in the pole group being unable to be effectively implemented and unable to effectively contact the hot melt adhesive, resulting in only the connecting strip and the hot melt adhesive being bonded. In addition, after the hot melt adhesive is added in winter, it cools down quickly, and the adhesion between the lining strip and the hot melt adhesive is poor, resulting in shaking at the bottom of the pole group, reducing the vibration resistance of the battery, thereby increasing the probability of failure modes such as plate ear breakage, grid rib breakage, and bus breakage, and reducing the service life of the battery.

[0003] In addition, since there are welding holes between battery cells, the adjacent pole groups are filled with melted lead by the welding machine and then become a whole after cooling. After the pole groups are cast-welded, the positive and negative poles will fluctuate due to the positioning accuracy of the fixture, and there will be a certain height difference, which will be reflected in the offset of the welding lead parts. If the pole group is raised, this offset will increase. When the lead liquid is filled to the welding hole, it will overflow, causing the welding lead to pierce. Summary of the invention

[0004] The utility model aims to solve the above-mentioned deficiencies of the prior art, thereby providing a vibration-resistant storage battery and a battery tank, which can improve the strength of the tank body and reduce the displacement of the pole group inside the tank cell due to external vibration.

[0005] A vibration-resistant storage battery comprises a battery tank body, a battery upper cover, a pole group installed in the battery tank body and a liner assembly;

When the pole group is placed in each single cell of the battery slot body through the liner assembly, the two connecting belts on the bottom surface of the receiving groove are placed in the sedimentation grooves at both ends of the single cell, and the outer side surfaces of the front and rear groove walls of the receiving groove are against the ribs on the opposite inner wall of the single cell.

[0017] The utility model has a continuous concave sedimentation groove at the bottom of the battery slot, and the sedimentation grooves on both sides provide accommodating space for the liner connecting belt, so as to avoid the connecting belt padding the pole group after entering the slot, so that the pole group can be effectively implemented on the upper surface of the boss formed between the sedimentation grooves, and bonded with the hot melt adhesive added on the upper surface of the boss formed between the sedimentation grooves, so that the bottom of the pole group is bonded to the slot body as a whole, thereby improving its vibration resistance.

[0027] like Figure 1 , Figure 2 , Figure 4 , Figure 7 As shown, Figure 1 The left half is an external front view of the front side wall of the battery container body 1, and the right half is Figure 2 AA section view, Figure 2 The left half of Figure 1The left half is a W-direction view, and the right half is a top view of the right half of the battery tank body 1. The battery tank body 1 is divided into 6 2*3 cells 10 by the partition wall 3. There are two convex ridges 4 that continuously protrude upward in the middle of the bottom surface of the cell 10, and finally three sedimentation grooves 7 are formed at the bottom of the cell, of which two sedimentation grooves 7 are symmetrically located at the two ends of the cell, and the other is located in the middle of the cell. The width of the ridge 4 is 40mm. The liner assembly is made of PP modified material. The lining plate assembly includes a left lining plate, a right lining plate, and a connecting belt 9 for connecting the left lining plate and the right lining plate. A plurality of through holes are arranged on the left lining plate. The left lining plate has the same structure as the right lining plate. The left lining plate and the right lining plate are bent along the end of the connecting belt 9 to form a receiving groove. The front and rear groove walls of the receiving groove are the left lining plate and the right lining plate. The bottom surface of the receiving groove is two connecting belts 9. When the pole group is placed in each single cell 10 of the battery slot body 1 through the lining plate assembly, the two connecting belts 9 on the bottom surface of the receiving groove are placed in the sedimentation grooves 7 at both ends of the single cell 10. The outer side surfaces of the front and rear groove walls of the receiving groove are against the ribs on the inner wall of the single cell 10. The bottom surface of the pole group can be implemented on the convex ridge 4. Adding hot melt adhesive on the convex ridge 4 can effectively implement the pole group and add hot melt adhesive to the sedimentation tank, so that the bottom of the pole group is bonded to the tank body as a whole, thereby improving its vibration resistance. The width of the connecting belt 9 is 6mm and the thickness is 1mm. The depth of the sedimentation tank 7 needs to be greater than the thickness of the connecting belt 9, and the width also needs to be greater than the width of the connecting belt 9. The ridge depth is 3mm and the ridge width is 40mm. The hot melt adhesive has fluidity before it is completely cooled. The size of 40mm can ensure that it will not overflow when added to the ridge. After the active material softens and falls off in the later stage of battery use, it can be deposited in the sedimentation tank to reduce the risk of short circuit in the joint.

[0028] The outer side of the front and rear walls of the battery tank body 1 has grid-shaped reinforcement ribs, with a grid size of 18*12mm and a spacing of 2mm. The battery tank body 1 is made of PP modified material. The tank body is sturdy and will not wear or leak during use. The outer end surfaces of the left and right side walls of the battery tank body 1 are designed to be smooth, which is convenient for cleaning the acid water attached to the side after the battery production is completed.

[0029] like Figure 3 As shown, a smooth area 2 is designed in the middle of the rear side wall of the battery tank body 1, with a size of 91*214mm and a 6mm inward depression, so as to facilitate the laser grooving of the tank body to distinguish different types of batteries.

[0030] like Figure 5 , Figure 6 As shown, there are 8 vertically extending ribs on the relative inner walls of each single cell, of which 4 short ribs 5 are grouped in two and are arranged at both ends of the single cell, and the spacing between the two short ribs 5 in the same group is 9 mm. The other 4 long ribs 6 are grouped in two and are located in the middle of the single cell, and the distance between the two long ribs 6 is 9 mm. The other two long ribs 6 are arranged on the outside of the two middle long ribs 6.

[0031] The function of the four long ribs is to have a reverse clamping force on the pole group after the pole group is put in place. The four long ribs increase the strength of the entire inner side of the slot body. The width of the ribs is 1.5mm, and the upper ends of the ribs are all inclined surfaces. The inclination of the upper end inclined surface of the long rib 6 is greater than the inclination of the upper end inclined surface of the four short ribs 5, which facilitates the pole group to enter the slot smoothly under tight assembly. At the same time, since the pole group is tightly assembled after entering the slot, a battery has 6 cells. After the pole group enters the slot, the middle partition wall will be deformed to a certain extent under tight assembly, which may easily cause the pole groups of adjacent cells to fail to enter the slot smoothly. The present application sets ribs with a certain elasticity to avoid deformation of the middle partition board, ensure that the pole groups of adjacent cells can enter the slot smoothly, improve the deformation resistance of the outer wall of the slot, and prevent the pole group on the other side from failing to enter the slot smoothly due to deformation of the partition wall.

[0032] The above description is only an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
