Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, and more particularly to lead-acid storage batteries. Background Technology

[0002] Lead-acid batteries, as rechargeable and rechargeable chemical power sources, are widely used in automotive starting and power supply for onboard electrical equipment. Their core structure includes lead-based active material electrodes, sulfuric acid electrolyte, and separator components, achieving energy storage and release through electrochemical reactions. In automotive applications, lead-acid batteries must simultaneously meet the technical requirements of high-rate discharge (e.g., engine starting) and long-cycle float charging (e.g., powering onboard electronic devices).

[0003] Existing automotive lead-acid battery installation technologies mainly employ two types of protective designs: one uses a rigid protective structure that encases the battery body in a metal casing, and the other uses elastic buffer brackets to achieve vibration isolation. However, both of these solutions have significant drawbacks: while the rigid protective structure can withstand external impacts, it results in a rigid connection between the battery module and the mounting bracket, which can easily lead to loosening of the connecting bolts under long-term vibration conditions in a vehicle; the elastic buffer solution can absorb vibration energy, but it increases the number of steps involved in battery installation and removal, and the fatigue and aging of the buffer components can further reduce system reliability. Therefore, existing technologies cannot simultaneously protect the battery and enable rapid installation and removal. Utility Model Content

[0004] To address the problem that existing technologies cannot simultaneously protect batteries and enable rapid installation and removal, the present invention aims to provide a lead-acid battery, the specific technical solution of which is as follows: Lead-acid batteries, including: Battery body; A protection plate is detachably connected to the battery body, and a buffer is provided on the inner side wall of the protection plate; A support structure is provided on the bottom wall of the protective plate; A blocking structure is movably disposed on the protective plate. The blocking structure can move relative to the protective plate between a clearance position and a blocking position. When the blocking structure is in the clearance position, the battery body can be installed or removed. When the blocking structure is in the blocking position, the battery body can be restricted from moving in the removal direction.

[0005] In some embodiments, the support structure includes a first elastic element, and the protective plate is provided with a first slot, with the first elastic element disposed within the first slot.

[0006] In some embodiments, the support structure includes a top plate that is movable up and down along the height of the lead-acid battery.

[0007] In some embodiments, in the initial state, the top plate protrudes from the bottom wall of the protective plate under the force of the first elastic member.

[0008] In some embodiments, a first limiting block is provided on the opening of the first slot, and a first pressure plate is provided between the first elastic member and the top plate, the first pressure plate being able to abut against the first limiting block.

[0009] In some embodiments, the blocking structure includes a second elastic element, and the protective plate is provided with a second slot, with the second elastic element disposed within the second slot.

[0010] In some embodiments, the blocking structure includes a limiting plate that can be concealed within the second slot.

[0011] In some embodiments, in the initial state, the second elastic member always keeps the limiting plate protruding relative to the second slot, and the limiting plate can be exposed outside the second slot.

[0012] In some embodiments, a second limiting block is provided on the opening of the second slot, and a second pressure plate is provided between the second elastic member and the limiting plate, the second pressure plate being able to abut against the second limiting block.

[0013] In some embodiments, a third slot is provided on the inner sidewall of the protective plate, and a connecting strip is provided in the third slot, and the battery body is slidably connected to the third slot.

[0014] Compared with existing technologies, this utility model of lead-acid battery has the following advantages: By incorporating a buffer component, when the lead-acid battery is subjected to accidental collisions or impacts along its length and / or width during transportation and use, the buffer component can quickly deform due to its good elasticity, effectively absorbing and dispersing the impact energy. This provides all-round and reliable lateral buffer protection for the battery body, greatly reducing the risk of damage to the battery body due to collisions and significantly extending the battery's service life. By incorporating a support structure, a uniform and stable support force can be generated for the battery body during installation, ensuring a tight fit between the battery body and the protective structure, achieving a stable and secure installation effect. Simultaneously, when the battery body is impacted along the height direction of the lead-acid battery, the support structure can form longitudinal buffer protection, further protecting the battery body from damage. By incorporating a blocking structure, the installation and removal of the battery body are greatly facilitated. When the blocking structure is in the avoidance position, the battery body can be installed or removed; when the blocking structure is in the blocking position, it can restrict the movement of the battery body in the removal direction. This utility model of lead-acid battery, through the synergistic action of buffer components, support buffer components, and blocking and limiting components, not only provides all-round buffer protection for the battery body, effectively preventing damage to the battery body from collisions under various working conditions, but also improves the efficiency of battery body installation and disassembly, reduces maintenance costs, and provides strong guarantee for the safe, reliable use and convenient maintenance of lead-acid batteries, with significant economic and social benefits.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] It should be noted that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] The following descriptions of directions are defined as follows: The length direction of the lead-acid battery is set as the X direction, where the direction of movement toward the inside of the protection board 1 is the installation direction (+X direction), and the opposite direction is the removal direction (-X direction). The width direction of the lead-acid battery is set as the Y direction, and the height direction of the lead-acid battery is set as the Z direction.

[0023] like Figures 1-6As shown, this embodiment provides a lead-acid battery, including a protection plate 1 and a battery body 2, which are detachably connected. Specifically, the protection plate 1 has an opening 11 in the Y direction, and the battery body 2 is pushed into the inner cavity of the protection plate 1 through the opening 11 along the installation direction (+X direction). A buffer member 3 is provided on the inner sidewall 12 of the protection plate 1. The end of the buffer member 3 away from the protection plate 1 can abut against the sidewall of the battery body 2 to form a lateral buffer protection. When the battery body 2 is subjected to an impact along the X direction and / or Y direction, the buffer member 3 can achieve the effect of protecting the battery body 2. In this embodiment, the buffer member 3 includes several pads, which can be made of elastic material. A support structure 4 is provided on the bottom wall 13 of the protection plate 1. The support structure 4 is used to support the battery body 2. When the battery body 2 is subjected to an impact along the Z direction, the support structure 4 can form a longitudinal buffer protection. The support structure 4 includes a first elastic element 41 and a top plate 42. The top plate 42 is disposed on the bottom wall 13 of the protective plate 1. The bottom wall 13 of the protective plate 1 has a first slot 14, and the first elastic element 41 is disposed within the first slot 14. Specifically, the first elastic element 41 can be a spring. In the initial state (i.e., before the battery body 2 enters the protective plate 1), the top plate 42 protrudes from the bottom wall 13 under the force of the first elastic element 41. In this embodiment, the top plate 42 can move up and down along the height direction (Z direction) of the lead-acid battery, and the end of the top plate 42 away from the first elastic element 41 can abut against the bottom of the battery body 2. In this embodiment, two sets of first elastic elements 41 and top plates 42 are provided, symmetrically distributed in the center-of-gravity projection area of ​​the battery body 2, with each first elastic element 41 corresponding to each top plate 42. A blocking structure 5 is provided on the bottom wall 13 of the protective plate 1 near the opening 11. The blocking structure 5 is used to prevent the battery body 2 from moving in the removal direction (-X direction). The blocking structure 5 is movably disposed on the protective plate 1 and can move relative to the protective plate 1 between a clearance position (i.e., the blocking structure 5 is hidden inside the protective plate 1) and a blocking position (i.e., the blocking structure 5 extends out of the bottom wall 13 of the protective plate 1). In this embodiment, the blocking structure 5 can move up and down along the Z direction. When the blocking structure 5 is in the clearance position, the battery body 2 can be quickly installed and removed. When the blocking structure 5 is in the blocking position, it can restrict the movement of the battery body 2 in the removal direction (-X direction). The blocking structure 5 includes a second elastic member 52 and a limiting plate 51. The limiting plate 51 is disposed on the bottom wall 13 of the protective plate 1 near the opening 11 and extends upward along the Z direction. A second slot 15 is provided on the bottom wall 13 of the protective plate 1, and the second elastic member 52 is disposed in the second slot 15. Specifically, the second elastic member 52 can be a spring. In the initial state, the second elastic member 52 always keeps the limiting plate 51 protruding relative to the second slot 15, and the limiting plate 51 can be exposed outside the second slot 15.In this embodiment, the limiting plate 51 can move up and down within the second slot 15 along the height direction (Z direction) of the lead-acid battery.

[0024] like Figure 2 , Figure 5 As shown, in this embodiment, to prevent the top plate 42 from detaching from the protective plate 1 when it moves in the Z direction, a first limiting block 141 is provided on the opening of the first slot 14, and a first pressure plate 43 is provided between the first elastic member 41 and the top plate 42. The first pressure plate 43 can abut against the first limiting block 141. Specifically, one end of the first pressure plate 43 is connected to the first elastic member 41, and the end of the first pressure plate 43 away from the first elastic member 41 is connected to the top plate 42. When the top plate 42 moves in the Z direction under the elastic force of the first elastic member 41, the first pressure plate 43 is blocked by the first limiting block 141, preventing the top plate 42 from detaching from the protective plate 1.

[0025] like Figure 2 , Figure 6 As shown, in this embodiment, to prevent the limiting plate 51 from falling off during the limiting process, a second limiting block 151 is provided on the slot of the second slot 15, and a second pressure plate 53 is provided between the second elastic member 52 and the limiting plate 51. The second pressure plate 53 can abut against the second limiting block 151. Specifically, one end of the second pressure plate 53 is connected to the second elastic member 52, and the end of the second pressure plate 53 away from the second elastic member 52 is connected to the limiting plate 51. The second pressure plate 53 can be abutted and limited by the second limiting block 151 to prevent the limiting plate 51 from falling off from the protective plate 1 when the limiting plate 51 is released. When the battery body 2 is pushed into the protection plate 1 along the X direction, the battery body 2 presses the limiting plate 51 down along the Z direction until the battery body 2 is completely inside the cavity of the protection plate 1. At this point, the limiting plate 51 loses its constraint on the battery body 2, and the second elastic element 52 releases its potential energy, causing the limiting plate 51 to move up along the Z direction, thus blocking the battery body 2 and limiting its movement to prevent it from detaching. When the limiting is released, simply press the limiting plate 51 to hide it in the protection plate 1, and then the battery body 2 can be detached, improving the efficiency of subsequent maintenance.

[0026] like Figure 3As shown, a mounting block 21 is provided on the battery body 2, and a third slot 16 is provided on the inner sidewall 12 of the protective plate 1. A connecting strip 6 is provided in the third slot 16, and the mounting block 21 on the battery body 2 is slidably connected to the third slot 16. In this embodiment, the connecting strip 6 can undergo elastic deformation. When the battery body 2 enters the third slot 16, it will squeeze the connecting strip 6, so that the connecting strip 6 can fit tightly against the outside of the battery body 2. When the battery body 2 is pushed into the protection plate 1 along the X direction, the top plate 42 will be squeezed. When the top plate 42 is squeezed, the first elastic member 41 will be squeezed through the first pressure plate 43, so that the first elastic member 41 will deform and release space at the same time, allowing the top plate 42 to apply upward pressure in the Z direction to the battery body 2. Since the mounting block 21 of the battery body 2 will generate a part of the gap in the third slot 16 after entering the third slot 16, the first elastic member 41 will act on the battery body 2 through the top plate 42, so that the gap between the mounting block 21 of the battery body 2 and the third slot 16 can be filled, and the battery body 2 can be kept more stable when installed in the protection plate 1.

[0027] like Figure 2 As shown, the inner wall 12 of the protective plate 1 is provided with an installation part 7. The installation part 7 is used to install the heat insulation pad. When the heat insulation pad is put into the battery body 2, the edge of the heat insulation pad is inserted into the installation part 7. At the same time, the buffer 3 presses the heat insulation pad tightly onto the surface of the battery body 2 through elastic potential energy, so as to achieve gapless heat insulation protection.

[0028] like Figures 1-2 As shown, a fixing part 8 is provided at one end of the bottom wall 13 of the protective plate 1 near the opening 11. The fixing part 8 can be fixed to the vehicle body with bolts to prevent displacement under vibration conditions.

[0029] The working process of this embodiment is as follows: First, align the battery body 2 with the opening 11 of the protection plate 1, align the mounting block 21 of the battery body 2 with the third slot 16, and push it into the inner cavity of the protection plate 1 along the installation direction (+X direction). During this process, the battery body 2 gradually approaches the limiting plate 51 and applies downward pressure along the Z direction to the limiting plate 51, causing the limiting plate 51 to press down along the Z direction within the second slot 15 until the limiting plate 51 is hidden within the second slot 15. At the same time, the mounting block 21 of the battery body 2 contacts and presses against the connecting strip 6, causing the connecting strip 6 to undergo elastic deformation and tightly adhere to the side wall of the battery body 2. Then, continue pushing the battery body 2 along the installation direction (+X direction), until the bottom of the battery body 2 contacts and is pressed against the top plate 42. After being compressed, the first elastic element 41 provides upward support to the top plate 42, ensuring that the top plate 42 remains protruding from the bottom wall 13. At this time, the battery body 2 moves upward along the Z-direction, gradually filling the gap between the mounting block 21 and the third slot 16, making the connection between the battery body 2 and the protection plate 1 tighter and more stable. When the battery body 2 is fully pushed into the cavity of the protection plate 1, the battery body 2 disengages from the limiting plate 51. At this point, the second elastic element 52, under its own elastic potential energy, pushes the limiting plate 51 upward along the Z-direction through the second pressure plate 53 until the limiting plate 51 returns to its initial state (i.e., the limiting plate 51 protrudes from the second slot 15), preventing the battery body 2 from detaching in the removal direction (-X direction). This completes the installation of the battery body 2. When maintenance and disassembly of the battery body 2 are required, the limiting plate 51 is pressed down, overcoming the elastic force of the second elastic element 52, and pressed downward along the Z-direction until it is hidden within the second slot 15. Then, pull the battery body 2 out in the removal direction (-X direction). During the pulling process, the connecting strip 6 gradually returns to its initial state until the battery body 2 is completely pulled out of the inner cavity of the protection plate 1, thus completing the disassembly of the battery body 2.

[0030] In this embodiment, the lead-acid battery is equipped with a buffer 3. When the lead-acid battery is subjected to accidental collisions or impacts along the length direction (X direction) and / or width direction (Y direction) during transportation and use, the buffer 3 can quickly deform due to its good elasticity, effectively absorbing and dispersing the impact energy. This provides all-round and reliable lateral buffer protection for the battery body 2, greatly reducing the risk of damage to the battery body 2 due to collisions and significantly extending the battery's service life. The support structure 4 provides uniform and stable support for the battery body 2 during installation, ensuring a tight fit between the battery body 2 and the protective structure, achieving a stable and secure installation. Simultaneously, when the battery body 2 is impacted along the height direction (Z direction), the support structure 4 forms longitudinal buffer protection, further protecting the battery body 2 from damage. The blocking structure 5 greatly facilitates the installation and removal of the battery body 2. When maintenance and disassembly of the battery body 2 are required, the blocking structure 5 is pressed until it is hidden inside the protective plate 1, and the battery body 2 can be moved in the removal direction. During installation, when the battery body 2 is pushed into the inner cavity of the protection plate 1 along the installation direction (+X direction), the limiting plate 51 will press down under the push of the battery body 2, without obstructing the installation process. After the battery body 2 is fully installed, the limiting plate 51 automatically returns to its initial state under the action of the second elastic element 52, effectively locking the battery body 2 and preventing it from shifting or coming off under vibration or other conditions. When the battery body 2 needs to be disassembled for subsequent maintenance, simply press the limiting plate 51 down until it is hidden in the second slot 15, and the battery body 2 can be pulled out along the removal direction (-X direction). The operation is simple and quick, greatly improving maintenance efficiency.
