Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a shock-absorbing, drop-resistant, high-strength storage battery. Background Art

[0002] A battery is a device that converts chemical energy into electrical energy. It is mainly used in energy storage and other fields. With the development of new energy technologies, higher and higher requirements have been put forward for the development of battery technology, resulting in many types of batteries, such as lithium batteries, sodium batteries, etc., and batteries are also of great significance in the manufacture of automobiles. Whether it is a traditional gasoline car, a diesel car, or a new energy car that is currently developing rapidly, batteries are important components and play a vital role in the operation of the car. However, since the car will produce bumps during driving, and even very large bumps, the battery needs to reasonably solve the problem of shock absorption when installed in the car. For some batteries, the use of simple spring shock absorption will solve the problem of hard impact, but every time the car bumps, the battery will have a certain degree of shaking, which is not conducive to the durable use of the battery. On the other hand, in some special circumstances, such as when a car passes through a deep pothole or a curb with a large height difference, a strong hard impact will occur. After this situation, the battery may still be used normally in a short period of time, but when the vehicle undergoes routine maintenance, the maintenance personnel cannot or the battery will receive an impact in this situation, and therefore cannot inspect and maintain it. Summary of the invention

[0003] Purpose of the invention: This application aims to overcome the defects of the prior art and provide a shock-absorbing and drop-resistant high-strength battery.

[0004] Technical solution: A battery comprises a battery body and a shock absorbing part, wherein the battery body comprises an outer shell and a top cover, a positive electrode column and a negative electrode column are installed on the top cover, and a positive electrode plate, a negative electrode plate, a separator and an electrolyte are arranged in the outer shell; the shock absorbing part comprises two shock absorbing units, and the shock absorbing unit comprises a bottom substrate, a first supporting unit fixed on the bottom substrate and a rubber block installed on the top of the first supporting unit, and the lower surface of the outer shell of the battery body abuts against the rubber block.

[0005] Further, side connection units are fixed to both sides of the housing. The two side connection units correspond to the two shock absorption units one by one. The side connection unit includes a strip-shaped fixing block fixed to the side of the housing, and the strip-shaped fixing block has an insertion block slot; the shock absorption unit further includes a fixing frame, the fixing frame includes two support plates, a strip-shaped rotating block is hinged between the two support plates, and the strip-shaped rotating block is connected with a strip-shaped insertion block inserted into the insertion block slot through a plurality of first springs; the two shock absorption units are respectively a first shock absorption unit and a second shock absorption unit. An insertion plate groove is provided at the bottom substrate of the first shock absorption unit, an insertion plate is fixedly connected to the bottom substrate of the second shock absorption unit, and a plurality of locking bolts for locking the relative positions of the insertion plate and the insertion plate groove are further provided at the bottom substrate of the first shock absorption unit.

[0006] Further, the fixing frame further includes an L-shaped plate connected to both support plates. The L-shaped plate includes a horizontal plate and a vertical plate. A fixed limiting plate is fixed to the vertical plate. The fixed limiting plate has a horizontal sleeve plate inserted by the fixed limiting plate. The horizontal sleeve plate has an insertion groove inserted by the fixed limiting plate. A plurality of second springs are connected between the end of the fixed limiting plate and the end of the insertion groove. The strip-shaped rotating block includes a semi-cylindrical part and a cuboid part connected to the semi-cylindrical part. A limiting slot is provided at the semi-cylindrical part. The horizontal sleeve plate abuts against the semi-cylindrical part of the strip-shaped rotating block; a second support unit is further fixed to the bottom substrate. The number of the second support units at the bottom substrate is equal to the number of the first support units. The second support unit includes a surrounding ring surrounding the first support unit and a plurality of support rods connecting the bottom substrate and the surrounding ring. The first support unit includes a bottom fixing block fixed to the bottom substrate, a lower support block connected to the bottom fixing block, a top fixing block fixed to the rubber block, an upper support block connected to the top fixing block, and a fragile part connecting the upper support block and the lower support block. The upper surface of the surrounding ring is lower than the lower surface of the rubber block.

[0007] Further, both the top fixing block and the bottom fixing block are cylindrical.

[0008] Further, when all the fragile parts of the two shock absorption units are broken, the two horizontal sleeve plates are inserted into the corresponding limiting slots, and the housing of the battery body abuts against all the surrounding rings.

[0009] Further, the surrounding ring is made of a foaming material.

[0010] Thus, a good and softer shock absorption effect is provided.

[0011] Further, two first support units and two second support units are fixed to the bottom substrate of each shock absorption unit.

[0012] Preferably, the first supporting unit and the bottom base plate are fixedly connected by bolts.

[0013] Preferably, the first supporting unit and the rubber block are fixedly connected by bolts.

[0014] This makes it easy to install and disassemble the first support unit, thereby facilitating replacement of the first support unit.

[0015] Furthermore, the end of the horizontal sleeve plate abutting against the bar-shaped rotating block is in an arc shape.

[0016] Therefore, under normal circumstances, the abutment between the bar-shaped rotating block and the horizontal sleeve plate causes less wear between them.

[0017] Furthermore, the bottom substrate has a mounting through hole.

[0018] This makes it easier to fix and install the bottom substrate and other components.

[0019] Furthermore, the lower surface of the bottom substrate of the first shock absorbing unit has a strip-shaped groove, and all the locking bolts are located in the strip-shaped groove.

[0020] Thereby, the distance between the two damping units can be fixed and the bottom ends of the two bottom substrates can be made flatter.

[0021] Furthermore, the side connection unit also includes an end cover, one end of the plug slot is open, the end cover is connected to the strip fixing block by bolts, the end cover is fixed to the open end of the plug slot, and the end cover includes an end plate and an end plug fixedly connected to the end plate and inserted into the open end of the plug slot.

[0022] Furthermore, the strip-shaped plug block includes a first strip-shaped block with an arc surface and a second strip-shaped block in a rectangular shape; the plug block slot includes a first strip-shaped groove with an arc surface, a second strip-shaped groove connected to the first strip-shaped groove, and a third strip-shaped groove connected to the second strip-shaped groove, the third strip-shaped groove is used to allow the second strip-shaped block to pass through and provide space for the rotation of the second strip-shaped block; when the end cover is not removed, the first strip-shaped block can rotate in the first strip-shaped groove but cannot fall off from the first strip-shaped groove.

[0023] Therefore, the strip-shaped plug-in block and the plug-in block slot are actually hingedly mounted and can rotate relative to each other.

[0024] Furthermore, the battery body is a lead-acid battery.

[0025] Beneficial effect: The battery of the present application has better shock absorption and fall resistance effect. During normal driving, it can provide shock absorption and will not cause the battery to shake, ensuring the protection and use of the battery under conventional non-extreme roads.

[0026] In addition, when the storage battery of the present application encounters an ultra-strong impact, it can achieve force relief and shock absorption, resolve this ultra-conventional impact through force relief, and then quickly switch to shock absorption in another state, and still maintain a good shock absorption effect in this state. In addition, during the regular maintenance of the vehicle, by checking the shock absorption state, it is easy to determine whether the storage battery has experienced an ultra-conventional impact, so as to make the maintenance of the storage battery more targeted.

[0041] As shown in the figure: A shock-absorbing and anti-drop high-strength storage battery, including a storage battery body 6 and a shock-absorbing part. The storage battery body 6 includes a housing and a top cover. A positive electrode post 6.1 and a negative electrode post 6.2 are installed at the top cover. Inside the housing, there are a positive electrode plate, a negative electrode plate, a separator, and electrolyte. The shock-absorbing part includes two shock-absorbing units. The shock-absorbing unit includes a bottom substrate 1, a first support unit fixed to the bottom substrate 1, and a rubber block 2.4 installed at the top of the first support unit.

The strip-shaped rotating block 5.1 includes a semi-cylindrical part and a rectangular parallelepiped part connected to the semi-cylindrical part. The semi-cylindrical part has a limiting slot 5.1.1. The horizontal sleeve plate 4.5 abuts against the semi-cylindrical part of the strip-shaped rotating block 5.1. A second support unit is also fixed to the bottom substrate 1. The number of the second support units at the bottom substrate is equal to the number of the first support units. The second support unit includes a surrounding ring 1.2 surrounding the first support unit and a plurality of support rods 1.1 connecting the bottom substrate 1 and the surrounding ring 1.2. The first support unit includes a bottom fixing block 2.1 fixed to the bottom substrate 1, a lower support block 2.3.1 connected to the bottom fixing block 2.1, a top fixing block 2.2 fixed to the rubber block 2.4, an upper support block 2.3.2 connected to the top fixing block 2.2, and a fragile part 2.3.3 connecting the upper support block 2.3.2 and the lower support block 2.3.1. The upper surface of the surrounding ring 1.2 is lower than the lower surface of the rubber block 2.4.When all the vulnerable parts 2.3.3 of the two shock-absorbing units are broken, the two horizontal sleeve plates 4.5 are inserted into the corresponding limit slots 5.1.1, and the outer shell of the battery body 6 abuts against all the surrounding rings 1.2.

[0042] The surrounding ring 1.2 is made of foaming material; two first support units and two second support units are fixed at the bottom substrate 1 of each shock-absorbing unit; the end of the horizontal sleeve plate 4.5 that abuts against the strip-shaped rotating block 5.1 is arc-shaped. The bottom substrate 1 is provided with mounting through holes 1.6; the lower surface of the bottom substrate 1 of the first shock-absorbing unit has strip-shaped grooves 1.4, and all the locking bolts 1.5 are located at the strip-shaped grooves 1.4. The side connection unit further includes an end cover 5.5, one end of the insert slot is open, the end cover 5.5 and the strip-shaped fixing block 5.4 are connected by bolts, the end cover 5.5 is fixed at the open end of the insert slot, and the end cover 5.5 includes an end plate 5.5.1 and an end insert 5.5.2 that is fixedly connected to the end plate 5.5.1 and inserted into the open end of the insert slot. The strip-shaped insert 5.3 includes a first strip-shaped block 5.3.1 with an arc surface and a second strip-shaped block 5.3.2 in the shape of a cuboid; the insert slot includes a first strip-shaped groove 5.4.1 with an arc surface, a second strip-shaped groove 5.4.2 communicated with the first strip-shaped groove 5.4.1, and a third strip-shaped groove 5.4.3 communicated with the second strip-shaped groove 5.4.2. The third strip-shaped groove 5.4.3 is used for the second strip-shaped block 5.3.2 to pass through and provides space for the rotation of the second strip-shaped block 5.3.2; when the end cover 5.5 is not removed, the first strip-shaped block 5.3.1 can rotate in the first strip-shaped groove 5.4.1 but cannot fall off from the first strip-shaped groove 5.4.1.

[0043] As shown in the figure of the battery of the present application, the distance between the two shock-absorbing units can be adjusted, so that batteries with different specifications can be used. Under normal circumstances, since the battery is supported by multiple rubber blocks and is supported and pulled by multiple first springs on both sides, shock absorption is achieved. And at this time, since there are rubber blocks abutting against the battery, the battery will not shake up and down while shock absorption is achieved. At this time, the end of the horizontal sleeve plate will abut against the strip-shaped rotating block, but cannot be inserted into the limit slot.

[0044] When a strong impact occurs, the storage battery will generate a large downward force under the impact, so that the vulnerable part of the first support unit will break, and the storage battery can continue to move downward to release the force, avoiding the damage to the storage battery caused by such a hard impact. During the downward movement of the storage battery, the first springs on both sides are stretched, thus realizing buffering and resolving the downward force of the storage battery. And afterwards, the rubber block will fall on the surrounding ring, and the surrounding ring made of foaming material combines with the rubber block to provide better buffering. And at this time, due to the rotation of the strip-shaped rotating block, the horizontal sleeve plate is inserted into the limit slot, so that the position of the strip-shaped insertion block moves downward to reduce the height of the storage battery body. At this time, the first spring still plays a role in pulling and damping the storage battery body. Thus, at this time, the surrounding ring, the banana block and the first spring cooperate to form a new damping structure, and the damping structure at this time is softer and has a stronger damping effect. And at this time, due to the change of the damping structure, when the vehicle is maintained, the maintenance personnel can easily find that the storage battery has experienced a strong impact, so that the storage battery can be more comprehensively inspected and maintained.

[0045] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
