Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery box. Background Technology

[0002] Energy storage batteries are devices that convert chemical energy into electrical energy, such as lead-acid batteries or lithium batteries. Their working principle is that during charging, external electrical energy is used to regenerate the internal active materials, storing electrical energy as chemical energy; during discharging, the chemical energy is converted back into electrical energy for output.

[0003] Batteries are prone to swelling during prolonged use. If not maintained or replaced in time, the swollen battery can explode, posing a significant safety hazard. To improve battery safety, batteries are generally placed in explosion-proof battery cases. However, existing battery cases only accommodate one type of battery and cannot accommodate batteries of different sizes, causing inconvenience for maintenance and battery replacement.

The first mounting block and the second mounting block are spaced apart along a third direction and both have sliding grooves. The third direction intersects both the first direction and the second direction.

If a battery inside the box needs replacement due to expansion, it is not necessary to replace only batteries of the same size; batteries of different sizes can also be replaced, greatly improving the convenience of maintenance and battery replacement.

[0036] Please see Figures 1 to 3 This application provides a battery device, which includes a battery case and a battery A. The battery case is used to house the battery A, thereby providing protection for the battery A.

[0037] The battery box includes a housing 10, a first positioning assembly, and a second positioning assembly. The housing 10 has a receiving cavity for housing a battery A. Both the first and second positioning assemblies are disposed within this receiving cavity. The first positioning assembly includes a first adjustment unit 21 and two first clamping plates 22. The two first clamping plates 22 are respectively disposed on both sides of the battery A in a first direction X1 and are both connected to the first adjustment unit 21. The first adjustment unit 21 is configured to operably move the two first clamping plates 22 closer to or further away from each other, i.e., adjust the distance between the two first clamping plates 22. The second positioning assembly includes a second adjustment unit 31 and two second clamping plates 32. The two second clamping plates 32 are respectively disposed on both sides of the battery A in a second direction X2 and are both connected to the second adjustment unit 31. The first direction X1 intersects the second direction X2. Preferably, the first direction X1 is perpendicular to the second direction X2. The second adjustment unit 31 is configured to operably move the two second clamping plates 32 closer to or further away from each other, i.e., adjust the distance between the two second clamping plates 32.

[0038] Thus, within the receiving cavity of the housing 10, battery A is clamped by two first clamping plates 22 along a first direction X1, and battery A is clamped by two second clamping plates 32 along a second direction X2, thereby fixing battery A. Furthermore, the distance between the two first clamping plates 22 can be adjusted by the first adjustment unit 21, and the distance between the two second clamping plates 32 can be adjusted by the second adjustment unit 31, according to the size of battery A, to accommodate batteries A of different sizes. If battery A inside the housing 10 needs to be replaced due to expansion, it is not necessary to replace only batteries A of the same size; batteries A of different sizes can also be replaced, greatly improving the convenience of maintenance and battery replacement.

[0039] In a specific embodiment, the housing 10 includes multiple side plates 17 and a base 12. The side plates 17 are fixedly connected to the base 12 and are sequentially connected end to end. The side plates 17 and the base 12 together form the aforementioned receiving cavity. The battery box also includes a pad 14 (see...). Figure 7 The pad 14 is disposed on the side of the base 12 facing the receiving cavity, and the battery A is supported on the pad 14. Specifically, the shape of the box 10 is a cuboid, that is, it includes four side plates 17, which are connected end to end in sequence, wherein two side plates 17 are arranged opposite each other along the first direction X1, and the other two side plates 17 are arranged opposite each other along the second direction X2.

[0040] In the embodiments of this application, the first adjustment unit 21 includes a first rotating rod 215, a first gear 211, and two first racks 213. The first rotating rod 215 is rotatably connected to the base 12 of the housing 10, and the first gear 211 is mounted on the first rotating rod 215, so that the first gear 211 can rotate together with the first rotating rod 215. The two first racks 213 are movably connected to the base 12 of the housing 10 along a first direction X1. The first gear 211 is located between the two first racks 213 and meshes with the two first racks 213, so that when the first gear 211 rotates, it can drive the two first racks 213 to move in opposite directions. The two first clamping plates 22 are respectively fixedly connected to the two first racks 213, so that the two first racks 213 can respectively drive the two first clamping plates 22 to move closer or further apart in the first direction X1.

[0041] Thus, when it is necessary to reduce the distance between the two first clamping plates 22, the first rotating rod 215 is controlled to drive the first gear 211 to rotate in the first direction (i.e., Figure 3 As shown, the first gear rotates counterclockwise, thereby driving the two first clamping plates 22 to move closer together in the first direction X1 via the two first racks 213, thus reducing the distance between the two first clamping plates 22. When it is necessary to increase the distance between the two first clamping plates 22, the first rotating rod 215 is controlled to drive the first gear 211 to rotate in a second direction opposite to the first rotation direction (i.e., the first gear 211 rotates in a second rotation direction opposite to the first rotation direction). Figure 3 As shown in the clockwise direction, the two first racks 213 respectively drive the two first clamping plates 22 to move away from each other in the first direction X1, thereby achieving the purpose of increasing the distance between the two first clamping plates 22.

[0042] In a specific embodiment, the end of the first rotating rod 215 facing away from the first gear 211 passes through the base 12 of the housing 10 (i.e., extends outside the housing 10) and is connected to a first rotary valve 216. Thus, by turning the first rotary valve 216, the first rotating rod 215 can be rotated clockwise or counterclockwise, thereby increasing or decreasing the distance between the two first clamping plates 22.

[0043] Please see Figure 7 and Figure 8Specifically, in this embodiment, the first positioning component further includes a first anti-rotation unit 217, which is used to engage or disengage with the first rotating rod 215 to prevent rotation. When the first anti-rotation unit 217 engages with the first rotating rod 215, it can prevent the first rotating rod 215 from rotating, thus keeping the positions of the two first clamping plates 22 unchanged and continuously clamping and fixing the battery A. When the first anti-rotation unit 217 disengages from the first rotating rod 215, it can drive the first rotating rod 215 to rotate through the first rotary valve 216, thereby adjusting the distance between the two first clamping plates 22.

[0044] Further, the first anti-rotation unit 217 includes a first base 2171, a first elastic element 2173, a first pin 2172, and a first stop pin 2174. The first base 2171 is fixedly connected to the outside of the housing 10, and the first pin 2172 is movably connected to the first base 2171. The portion of the first rotating rod 215 extending outside the housing 10 has a first anti-rotation insertion hole 2151, which is opposite to the first pin 2172. One end of the first elastic element 2173 abuts against the first base 2171, and the other end of the first elastic element 2173 abuts against the first pin 2172, thereby increasing the elastic force that causes the first pin 2172 to have a tendency to insert into the first anti-rotation insertion hole 2151 of the first rotating rod 215. The first stop pin 2174 is rotatably connected to the first base 2171 and can be rotated to engage or disengage with the first pin 2172. When the first stop pin 2174 rotates to engage with the first pin 2172, the first stop pin 2174 prevents the first pin 2172 from inserting into the first anti-rotation insertion hole 2151 of the first rotating rod 215, thereby allowing the first rotating rod 215 to rotate via the first rotating valve 216. When the first stop pin 2174 rotates to disengage from the first pin 2172, the first pin 2172 moves towards the first rotating rod 215 under the elastic force provided by the first elastic member 2173 until it inserts into the first anti-rotation insertion hole 2151 of the first rotating rod 215, thereby preventing the first rotating rod 215 from rotating. Optionally, the first elastic member 2173 can be a compression spring.

[0045] Thus, when it is necessary to adjust the distance between the two first clamping plates 22, the first pin 2172 is first pulled out from the first anti-rotation insertion hole 2151, and the first stop pin 2174 is rotated to engage with the first pin 2172. Then, by turning the first rotary valve 216, the first rotating rod 215 is rotated, which in turn drives the first gear 211 to rotate. The first gear 211, through the two first racks 213, drives the two first clamping plates 22 to move closer or further apart along the first direction X1, thereby adjusting the distance between the two first clamping plates 22. After the distance between the two first clamping plates 22 is adjusted to the correct position, the turning of the first rotary valve 216 is stopped, and the first stop pin 2174 is rotated to separate from the first pin 2172, so that the first pin 2172, under the elastic force of the first elastic element 2173, is inserted into the first anti-rotation insertion hole 2151 of the first rotating rod 215, thereby preventing the first rotating rod 215 from rotating.

[0046] Please continue reading Figures 1 to 3 In the embodiments of this application, the second adjustment unit 31 includes a second rotating rod 315, a second gear 311, and two second racks 313. The second rotating rod 315 is rotatably connected to the base 12 of the housing 10, and the second gear 311 is mounted on the second rotating rod 315, so that the second gear 311 can rotate together with the second rotating rod 315. The two second racks 313 are movably connected to the base 12 of the housing 10 along the second direction X2. The second gear 311 is located between the two second racks 313 and meshes with the two second racks 313, so that when the second gear 311 rotates, it can drive the two second racks 313 to move in opposite directions. The two second clamping plates 32 are respectively fixedly connected to the two second racks 313, so that the two second racks 313 can respectively drive the two second clamping plates 32 to move closer or further apart in the second direction X2.

[0047] Thus, when it is necessary to reduce the distance between the two second clamping plates 32, the second rotating rod 315 is controlled to drive the second gear 311 to rotate in the first direction (i.e., Figure 3 As shown, the rotation is counterclockwise, thereby causing the two second racks 313 to drive the two second clamping plates 32 to move closer to each other in the second direction X2, thus reducing the distance between the two second clamping plates 32. When it is necessary to increase the distance between the two second clamping plates 32, the second rotating rod 315 is controlled to drive the second gear 311 to rotate in a second direction opposite to the first direction of rotation (i.e., the second gear 311 rotates in a second direction opposite to the first direction of rotation). Figure 3 As shown in the clockwise direction, the two second racks 313 respectively drive the two second clamping plates 32 to move away from each other in the second direction X2, thereby achieving the purpose of increasing the distance between the two second clamping plates 32.

[0048] In a specific embodiment, the end of the second rotating rod 315 facing away from the second gear 311 passes through the base 12 of the housing 10 (extending beyond the housing 10) and is connected to a second rotary valve 316. Thus, by turning the second rotary valve 316, the second rotating rod 315 can be rotated clockwise or counterclockwise, thereby increasing or decreasing the distance between the two second clamping plates 32.

[0049] In a specific embodiment, the second positioning component further includes a second anti-rotation unit 317, which is used to engage or disengage with the second rotating rod 315 to prevent rotation. When the second anti-rotation unit 317 engages with the second rotating rod 315, it prevents the second rotating rod 315 from rotating, thus keeping the positions of the two second clamping plates 32 unchanged and continuously clamping and fixing the battery A. When the second anti-rotation unit 317 disengages from the second rotating rod 315, it can drive the second rotating rod 315 to rotate through the second rotary valve 316, thereby adjusting the distance between the two second clamping plates 32.

[0050] It should be noted that the structure of the second anti-rotation unit 317 is similar to that of the first anti-rotation unit 217, so it will not be described in detail here.

[0051] Please see Figures 4 to 6 In embodiments of this application, the battery box further includes an explosion-proof component 24, which is mounted on the first clamping plate 22 and / or the second clamping plate 32. The box body 10 has explosion-proof openings 112 corresponding to each explosion-proof component 24 (see...). Figure 1 Each explosion-proof port 112 is connected to an explosion-proof membrane 15 (see...). Figure 1 The enclosure is sealed. Each explosion-proof component 24 can puncture the corresponding explosion-proof membrane 15 under the pushing force generated by the expansion of battery A. That is, if battery A expands, it will push the explosion-proof component 24, causing it to puncture the explosion-proof membrane 15 at the corresponding explosion-proof opening 112, thereby alerting the user that battery A has expanded and poses a safety hazard, requiring battery A to be replaced or maintained. At the same time, because the explosion-proof membrane 15 is punctured, the high-pressure gas inside the enclosure 10 is released through the opening formed by the puncture of the explosion-proof membrane 15, reducing the gas pressure inside the enclosure 10 and preventing an explosion.

[0052] It should be noted that the explosion-proof component 24 may be installed on only one of the two first clamping plates 22, or it may be installed on both first clamping plates 22. Similarly, the explosion-proof component 24 may be installed on only one of the two second clamping plates 32, or it may be installed on both second clamping plates 32. Specifically... Figure 3In the embodiment shown, only one of the two first clamping plates 22 is equipped with an explosion-proof component 24, and only one of the two second clamping plates 32 is equipped with an explosion-proof component 24.

[0053] The specific structures of each explosion-proof component 24 are roughly the same, differing only in their installation positions. For ease of description, the following description uses an explosion-proof component 24 installed on one of the first clamping plates 22 as an example to illustrate the specific structure of the explosion-proof component 24.

[0054] Specifically, in this embodiment, the explosion-proof component 24 includes a mounting bracket 241 and an explosion-proof unit 242, which includes a movable member 2423 and a ejector pin 2424. The mounting bracket 241 is fixedly connected to the first clamping plate 22, and the movable member 2423 is movably connected to the mounting bracket 241. The ejector pin 2424 is disposed on the mounting bracket 241 and located on the side of the movable member 2423 opposite to the battery A, so that when the battery A expands, the movable member 2423 can push the ejector pin 2424 to pierce the explosion-proof membrane 15 at the corresponding explosion-proof opening 112. Thus, when the battery A expands, the battery A will push the movable member 2423 relative to the mounting bracket 241 toward the ejector pin 2424, thereby the movable member 2423 pushing the ejector pin 2424 gradually closer to the corresponding explosion-proof opening 112 until the ejector pin 2424 pierces the explosion-proof membrane 15 at the corresponding explosion-proof opening 112.

[0055] Furthermore, the explosion-proof unit 242 also includes a first mounting block 2421 and a second mounting block 2422, both mounted on the mounting bracket 241. The first mounting block 2421 and the second mounting block 2422 are spaced apart along a third direction X3 and each has a groove B. This third direction X3 intersects both the first direction X1 and the second direction X2. Preferably, the first direction X1, the second direction X2, and the third direction X3 are perpendicular to each other. The movable member 2423 is a roller, with its two ends slidably disposed on the grooves B of the first mounting block 2421 and the second mounting block 2422, respectively, so that the roller can move along the groove B towards the ejector pin 2424 when the battery A expands due to the pressure of the battery A.

[0056] Furthermore, the explosion-proof unit 242 also includes a mounting arm 2425. This mounting arm 2425 is connected between the first mounting block 2421 and the second mounting block 2422, and is located on the side of the movable member 2423 opposite to the battery A. A ejector pin 2424 is fixedly connected to the mounting arm 2425. When the battery A expands, it compresses the movable member 2423, causing the movable member 2423 to push the ejector pin 2424 towards the corresponding explosion-proof opening 112. At this time, the mounting arm 2425 undergoes a certain elastic deformation, allowing the ejector pin 2424 to move towards the corresponding explosion-proof opening 112 and puncture the explosion-proof membrane 15 at the opening 112.

[0057] In some embodiments, for the explosion-proof assembly 24 mounted on the first clamping plate 22: the explosion-proof assembly 24 further includes a mounting plate 23, which is fixedly mounted on the first clamping plate 22. One end of the mounting bracket 241 is fixedly connected to the mounting plate 23 and extends to one side of the battery A in the second direction X2. That is, the first clamping plate 22 and the mounting plate 23 are located on one side of the battery A in the first direction X1, while the mounting bracket 241 and the explosion-proof unit 242 mounted on the mounting bracket 241 are located on one side of the battery A in the second direction X2. Thus, the explosion-proof assembly 24 mounted on the first clamping plate 22 can detect the expansion of the surface of the battery A on one side in the second direction X2 in real time.

[0058] It should be noted that the explosion-proof assembly 24 is not limited to including a single explosion-proof unit 242. In other embodiments, the explosion-proof assembly 24 may include multiple explosion-proof units 242, which are spaced apart and mounted on the mounting bracket 241 along the first direction X1. Thus, the expansion of the battery A at multiple locations on one side surface along the second direction X2 can be detected in real time using multiple explosion-proof units 242. Specifically... Figure 4 In the embodiment shown, the explosion-proof component 24 includes three explosion-proof units 242.

[0059] It should also be noted that the position of the mounting plate 23 relative to the first clamping plate 22 is adjustable along the second direction X2 to accommodate batteries A of different sizes. The position adjustment structure of the mounting plate 23 relative to the first clamping plate 22 can be implemented using relatively mature existing technologies, and is not limited here.

[0060] For the explosion-proof assembly 24 mounted on the second clamping plate 32: the explosion-proof assembly 24 also includes a mounting plate 23, which is fixedly mounted on the second clamping plate 32. One end of the mounting bracket 241 is fixedly connected to the mounting plate 23 and extends to one side of the battery A in the first direction X1. That is, the second clamping plate 32 and the mounting plate 23 are located on one side of the battery A in the second direction X2, while the mounting bracket 241 and the explosion-proof unit 242 mounted on the mounting bracket 241 are located on one side of the battery A in the first direction X1. In this way, the explosion-proof assembly 24 mounted on the second clamping plate 32 can detect the expansion of the surface of the battery A on one side in the first direction X1 in real time.

[0061] It should be noted that the explosion-proof assembly 24 is not limited to including only one explosion-proof unit 242. In other embodiments, the explosion-proof assembly 24 may include multiple explosion-proof units 242, which are spaced apart on the mounting bracket 241 along the second direction X2. In this way, the expansion of the battery A at multiple locations on one side surface in the first direction X1 can be detected in real time using multiple explosion-proof units 242.

[0062] It should also be noted that the position of the mounting plate 23 relative to the second clamping plate 32 is adjustable along the first direction X1 to accommodate batteries A of different sizes. The position adjustment structure of the mounting plate 23 relative to the second clamping plate 32 can be implemented using relatively mature existing technologies, and is not limited here.

[0063] In other embodiments, for the explosion-proof component 24 mounted on the first clamping plate 22: the mounting bracket 241 is fixedly connected to the first clamping plate 22 and is located on the same side of the battery A in the first direction X1. That is, the explosion-proof component 24 mounted on the first clamping plate 22 is located on the same side of the battery A in the first direction X1, so that the explosion-proof component 24 can detect the expansion of the surface of the battery A facing the first clamping plate 22 in real time.

[0064] For the explosion-proof component 24 installed on the second clamping plate 32: the mounting bracket 241 is fixedly connected to the second clamping plate 32 and is located on the same side of the battery A in the second direction X2. That is, the explosion-proof component 24 installed on the second clamping plate 32 is located on the same side of the battery A in the second direction X2, so that the explosion-proof component 24 can detect the expansion of the side surface of the battery A facing the second clamping plate 32 in real time.

[0065] Please see again Figure 1 In this embodiment of the application, the battery box further includes a switch cover assembly 40 and a cover 11. The top of the box body 10 has an opening, and the switch cover assembly 40 is movably connected to the box body 10 and conveyably connected to the cover 11. The switch cover assembly 40 is configured to operably drive the cover 11 to close or open the opening of the box body 10. Thus, when the explosion-proof component 24 detects that battery A has expanded and needs to be replaced, the switch cover assembly 40 drives the cover 11 to open the opening at the top of the box body 10, thereby allowing battery A to be replaced inside the box body 10 through the opening at the top of the box body 10. After battery A is replaced, the switch cover assembly 40 drives the cover 11 to close the opening at the top of the box body 10.

[0066] Specifically, in this embodiment, the switch cover assembly 40 includes a movable frame 41, a connecting plate 42, and a screw 43. The movable frame 41 is movably connected to the housing 10, and the connecting plate 42 is fixedly connected to the cover 11. The movable frame 41 has a threaded hole, through which the screw 43 is threadedly connected to the movable frame 41, and one end of the screw 43 is rotatably connected to the connecting plate 42. Thus, when it is necessary to open the opening at the top of the housing 10, firstly, the screw 43 is turned, causing the screw 43 to drive the cover 11 to rise relative to the housing 10 through the connecting plate 42, thereby separating it from the housing 10; then, the movable frame 41 is pushed to move relative to the housing 10 until the cover 11 is moved horizontally away from the top of the housing 10, so as to fully open the opening at the top of the housing 10, facilitating the maintenance or replacement of the battery A inside the housing 10. After battery A is maintained or replaced, push the moving frame 41 to move relative to the box 10 until the box cover 11 is moved horizontally above the box 10; then, turn the screw 43 in the opposite direction so that the screw 43 drives the box cover 11 to descend relative to the box 10 through the connecting plate 42 until the box cover 11 is engaged with the opening at the top of the box 10, thereby completely closing the opening at the top of the box 10.

[0067] Furthermore, guide grooves 101 are provided on both opposite sides of the housing 10. The movable frame 41 includes a first connecting section 411, an intermediate section 412, and a second connecting section 413. One end of the first connecting section 411 is slidably connected to the guide groove 101 on one side of the housing 10, and one end of the second connecting section 413 is slidably connected to the guide groove 101 on the other side of the housing 10. The other ends of the first connecting section 411 and the second connecting section 413 are respectively fixedly connected to the two ends of the intermediate section 412, and the intermediate section 412 is located above the housing 10. The aforementioned threaded hole is formed on the intermediate section 412, and the aforementioned screw 43 is threadedly connected to the intermediate section 412 through the threaded hole.

[0068] Furthermore, the switch cover assembly 40 also includes a guide post 44. A guide hole is provided on the middle section 412 of the moving frame 41, and the guide post 44 passes through the guide hole on the middle section 412. The bottom end of the guide post 44 is fixedly connected to the connecting plate 42. In this way, when the cover 11 is raised or lowered by turning the screw 43 through the connecting plate 42, the connecting plate 42 also drives the guide post 44 to rise or fall along the guide hole. Thus, the guide post 44 guides the lifting and lowering movement of the connecting plate 42 and the cover 11, preventing the cover 11 from shaking or getting stuck during the lifting and lowering process.

[0069] Optionally, there are two guide posts 44, and two guide holes are provided on the middle section 412 of the movable frame 41. The two guide posts 44 are respectively inserted into the two guide holes, and the bottom ends of the two guide posts 44 are fixedly connected to the connecting plate 42, so that the two guide posts 44 can simultaneously guide the lifting and lowering of the connecting plate 42 and the box cover 11. Furthermore, the two guide holes are located on opposite sides of the threaded hole.

[0070] Furthermore, the cover 11 has two through holes 110, which are used to install the two terminals A1 (i.e., the positive terminal and the negative terminal) of the battery A. The bottom of the box 10 is provided with at least two buffer support feet 13, which together support the box 10.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
