[0031] The utility model provides a pressure sensor, a solid-state battery, and a vehicle, which can improve the accuracy of the pressure sensor in detecting the pressure of a battery cell to ensure the safety of the battery. Detailed description is given below with reference to specific embodiments.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a pressure sensor, comprising a plurality of pressure sensing units 1, wherein the pressure sensing unit 1 comprises a first segment 11 and a second segment 12 connected to each other, wherein the second segment 12 is provided with a pressure sensing area 121, and the first segments 11 of the plurality of pressure sensing units 1 are stacked in sequence, and the second segments 12 of at least some of the pressure sensing units 1 are bent relative to the first segment 11 so that all the second segments 12 are staggered with each other.

[0033] Specifically, the pressure sensor 10 may be a thin film pressure sensor, and each pressure sensing unit 1 may be in the form of a sheet. It should be noted that there is no limitation on the specific number of the multiple pressure sensing units 1, and it may be two or more. More specifically, the first sections 11 of the multiple pressure sensing units 1 are stacked in sequence along the thickness direction of the pressure sensor 10, and among the multiple pressure sensing units 1, the second sections 12 of at least some of the pressure sensing units 1 are bent toward one side in the width direction relative to the first section 11, so that all the second sections 12 are staggered with each other, that is, the second sections 12 do not overlap with each other. Take the number of pressure sensing units 1 as an example, as shown in FIG. Figure 1As shown, the first segments 11 of the three pressure sensing units 1 are stacked sequentially along the thickness direction of the pressure sensor 10. The second segment 12 of the middle pressure sensing unit 1 is not bent relative to the first segment 11. Of the two outer pressure sensing units 1, the second segment 12 of one is bent toward the left (positive direction of the Y axis) relative to the first segment 11, while the second segment 12 of the other is bent toward the right (negative direction of the Y axis) relative to the first segment 11. This results in the three second segments 12 being spaced sequentially along the width direction of the middle pressure sensing unit 1, so that all second segments 12 are staggered. It should also be noted that adjacent first segments can be bonded to each other to ensure that all first segments are connected as a whole, thus ensuring the integrity of the pressure sensor.

[0034] In addition, the pressure sensing area 121 may include a pressure-sensitive layer, which is made of a pressure-sensitive material and can sense pressure changes; an electrode layer may be provided on the pressure sensing unit 1, and the electrode layer extends from the second section 12 to the first section 11, and a pin connected to the electrode layer may be provided in the first section 11; after the pressure-sensitive layer senses the pressure change, it can cause the electrode layer to generate a pressure signal, and the pressure signal is then transmitted to an external device through the pin, thereby realizing pressure detection.

[0035] In this embodiment, by bending the second sections 12 of some pressure sensing units 1 relative to the first sections 11 so that all the second sections 12 are staggered from each other, all the pressure sensing areas 121 can also be staggered from each other. In this way, the pressure sensor 10 can detect the pressure of different parts of the battery cell 21, and realize multi-point pressure detection of the battery cell 21, so as to more comprehensively know the pressure distribution of the battery cell 21, thereby improving the accuracy of pressure detection and ensuring the safety of the battery; in addition, by stacking the first sections 11 of multiple pressure sensing units 1 in sequence, partial overlap of multiple pressure sensing units 1 is achieved. This can, on the one hand, reduce the space occupied by the entire pressure sensor 10 in the battery, and on the other hand, can make the signals of multiple pressure sensing units 1 be led out at the same end position, which facilitates the electrical connection of the pressure sensor 10 with external equipment.

[0036] Alternatively, as Figure 1 and Figure 2 As shown, the multiple pressure sensing units 1 include a first pressure sensing unit 13 and a second pressure sensing unit 14, the first segment 11 of the first pressure sensing unit 13 and the first segment 11 of the second pressure sensing unit 14 are overlapped, and the second segment 12 of the second pressure sensing unit 14 is bent relative to the first segment 11 so that the second segment 12 of the first pressure sensing unit 13 and the second segment 12 of the second pressure sensing unit 14 are staggered with each other.

[0037] Specifically, if Figure 2As shown, for the second pressure sensing unit 14, the second section 12 starts to bend from the connection with the first section 11, and the bending angle can be approximately 120°, that is, the angle between the length direction of the second section 12 and the length direction of the first section 11 is approximately 120°. Moreover, after the second section 12 of the second pressure sensing unit 14 is bent relative to the first section 11, the second section 12 can form an angle of approximately 60° with the first pressure sensing unit 13.

[0038] In this optional embodiment, the first segment 11 of the first pressure sensing unit 13 and the first segment 11 of the second pressure sensing unit 14 are stacked, allowing the two pressure sensing units 1 to occupy only the area of ​​one first segment 11, effectively reducing their space usage within the battery. The second segments 12 of the first pressure sensing unit 13 and the second segments 12 of the second pressure sensing unit 14 are staggered, allowing the pressure sensing areas 121 of the two pressure sensing units 1 to be correspondingly staggered, facilitating detection of two different locations on the battery cell 21. Furthermore, the first pressure sensing unit 13 is linear and does not require bending, making it simple to manufacture.

[0039] Alternatively, as Figure 1 and Figure 2 As shown, the two second pressure sensing units 14 are stacked on both sides of the first pressure sensing unit 13, and the second sections 12 of the two second pressure sensing units 14 are bent toward different sides relative to the first section 11. The first pressure sensing unit 13 and the two second pressure sensing units 14 together form a trident structure.

[0040] Specifically, the two second pressure sensing units 14 are respectively stacked on both sides of the first pressure sensing unit 13 along the thickness direction. Figure 1 As shown, after the second sections 12 of the two second pressure sensing units 14 are bent toward different sides relative to the first section 11 , the second sections 12 of the two second pressure sensing units 14 are respectively located on both sides of the first pressure sensing unit 13 along its width direction.

[0041] In this optional embodiment, the two second pressure sensing units 14 are respectively stacked on both sides of the first pressure sensing unit 13, so that the three pressure sensing units 1 only occupy the area of ​​one first section 11, thereby effectively reducing their space occupancy in the battery; and the second sections 12 of the two second pressure sensing units 14 are bent toward different sides relative to the first section 11, and the first pressure sensing unit 13 and the two second pressure sensing units 14 together form a trident structure, which can make the pressure sensing areas 121 of the three pressure sensing units 1 staggered accordingly to facilitate the detection of three different parts of the battery cell 21.

[0042] Alternatively, as Figure 2As shown, the first section 11 and the second section 12 are sequentially connected along the length direction of the pressure sensing unit 1 , and a notch 15 is provided at at least one end of the connection between the first section 11 and the second section 12 along the width direction of the pressure sensing unit 1 .

[0043] Specifically, if Figure 2 As shown, two notches 15 may be provided at the connection between the first section 11 and the second section 12, and the two notches 15 are respectively connected to the two edges of the pressure sensing unit 1 along the width direction. Figure 2 As shown, for the first pressure sensing unit 13, the notch 15 thereof is substantially trapezoidal, and for the second pressure sensing unit 14, the second section 12 and the first section 11 can be bent at the notch position.

[0044] In this optional embodiment, the notch 15 can reduce the size of the pressure sensing unit 1, thereby reducing material costs. In addition, since the notch 15 is located at the connection between the first section 11 and the second section 12, the width of the connection between the first section 11 and the second section 12 is smaller. When the pressure sensor 10 is installed to the battery, the notch 15 can be used for clamping to ensure the positional stability of the pressure sensor 10, thereby ensuring the accuracy of pressure detection.

[0045] like Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a solid-state battery, including a module 20 and the pressure sensor 10 as described above; the module 20 includes a plurality of battery cells 21 stacked in sequence along its length direction; each second section 12 of the pressure sensor 10 is sandwiched between two of the battery cells 21, and each first section 11 of the pressure sensor 10 is located above the two of the battery cells 21.

[0046] Specifically, because each second section 12 of the pressure sensor 10 is sandwiched between two battery cells 21, it means that each pressure sensing area 121 is sandwiched between two battery cells 21. In this way, when the pressure of the battery cell 21 changes, the two battery cells 21 will expand and continuously squeeze the pressure sensing area 121 so that it senses the pressure change, thereby realizing pressure detection.

[0047] In addition, if Figure 4 and Figure 5 As shown, foam 23 can be sandwiched between the upper ends of the two battery cells 21 to reduce vibration of the two battery cells 21, and a through hole 231 can be provided on the foam 23, and the pressure sensor 10 passes through the through hole 231. Specifically, the part of the pressure sensor 10 with the notch 15 can be passed through the through hole 231 of the foam 23 to limit and fix the pressure sensor 10 through the foam 23.

[0048] In this embodiment, the second sections 12 of the pressure sensor 10 are sandwiched between the two battery cells 21 to facilitate pressure detection of the battery cells 21. Furthermore, since the first sections 11 are stacked, the entire structure is relatively thick. In this solution, the first sections 11 of the pressure sensor 10 are located above the two battery cells 21. This ensures that the thicker portion of the pressure sensor 10 is away from between the two battery cells 21, thereby preventing the thicker portion from hindering the expansion of the battery cells 21 and causing the pressure sensing area 121 to be unable to contact the battery cells 21, thereby affecting the normal detection of pressure.

[0049] Alternatively, as Figure 5 As shown, the second sections 12 of the pressure sensors 10 are distributed sequentially along the width direction of the module 20 .

[0050] Specifically, the number of pressure sensing units 1 of the pressure sensor 10 is three for illustration. Specifically, the three pressure sensing units 1 are a first pressure sensing unit 13 and two second pressure sensing units 14. The space between the two battery cells 21 is a first gap. The second section 12 of the first pressure sensing unit 13 can be in the middle of the first gap along the width direction of the module 20, and the second sections 12 of the two second pressure sensing units 14 gradually bend and extend to both ends of the first gap along the width direction of the module 20.

[0051] In this optional embodiment, because actual tests have shown that the pressure of the battery cell 21 usually varies along the width direction of the module 20, this solution distributes the second sections 12 of the pressure sensor 10 in sequence along the width direction of the module 20, so that each pressure sensing area 121 can sense the pressure at different pressure positions of the battery cell 21, thereby providing a more comprehensive understanding of the pressure situation of the battery cell 21 and improving the accuracy of pressure detection.

[0052] Alternatively, as Figure 6 As shown, the module 20 further includes an isolation plate 22 disposed on the upper ends of the plurality of battery cells 21 , and a through hole 221 is provided on the isolation plate 22 ; each of the first sections 11 of the pressure sensor 10 passes through the through hole 221 .

[0053] Specifically, the size of the through hole 221 may be adapted to the size of the pressure sensor 10 at the first section 11 .

[0054] In this optional embodiment, by providing an isolation plate 22 at the upper ends of multiple battery cells 21, the battery cells can be isolated from the bus, thereby avoiding unnecessary short circuits between different battery cells 21; in addition, by providing a through hole 221 on the isolation plate 22, and each first section 11 of the pressure sensor 10 passes through the through hole 221, so that the pressure sensor 10 can be electrically connected to the external device through the isolation plate 22 to transmit the pressure signal; and since the first sections 11 are stacked, only one through hole 221 needs to be designed for the pressure sensor 10 for the pressure sensor 10 to pass through, which can relatively reduce the number of openings on the isolation plate 22 and reduce the processing difficulty of the isolation plate 22.

[0055] In addition, if Figure 7 As shown, the upper end (first section 11 ) of the pressure sensor 10 can be bent along the length direction of the module 20 , which can prevent the pressure sensor 10 from excessively protruding from the module 20 and affecting the packaging of the entire battery.

[0056] Alternatively, as Figure 3 As shown, one module 20 corresponds to a plurality of pressure sensors 10 , and the plurality of pressure sensors 10 are sequentially distributed along the length direction of the corresponding module 20 and are respectively disposed between two different battery cells 21 .

[0057] It should be noted that there is no limit on the number of pressure sensors 10 provided on each module 20, and there can be two or more, for example, Figure 3 In FIG, there are four pressure sensors 10.

[0058] In this optional embodiment, because actual tests have shown that the pressure of the battery cells 21 at different positions along the length direction of the module 20 will vary, this solution provides a plurality of pressure sensors 10 on the module 20, and the plurality of pressure sensors 10 are distributed in sequence along the length direction of the module 20 and are respectively provided between two different battery cells 21, so that different pressure sensors 10 can correspondingly sense the pressure of the battery cells 21 at different positions, thereby providing a more comprehensive understanding of the pressure situation of the module 20 and improving the accuracy of pressure detection.

[0059] Alternatively, as Figure 8 As shown, there are multiple modules 20, and the multiple modules 20 include a high-temperature zone module and a low-temperature zone module. The pressure sensor 10 is respectively provided in the high-temperature zone module and the low-temperature zone module.

[0060] Specifically, among the multiple modules 20, there are two high temperature zone modules and two low temperature zone modules, and the two high temperature zone modules and the two low temperature zone modules are respectively provided with a pressure sensor 10. Figure 8As shown, the third module 20 from the left in the first row on the front side (positive direction of the X-axis) is a low-temperature zone module, the first module 20 from the right in the first row on the front side is a high-temperature zone module, the first module 20 from the left in the first row on the rear side (negative direction of the X-axis) is a high-temperature zone module, and the fourth module 20 from the right in the first row on the rear side is a low-temperature zone module.

[0061] In this optional embodiment, because actual tests have shown that the high-temperature zone usually has a higher pressure and the low-temperature zone usually has a lower pressure, that is, the modules 20 in the high-temperature zone and the low-temperature zone will have obvious pressure differences, this solution provides pressure sensors 10 in the high-temperature zone module and the low-temperature zone module respectively, so as to be able to monitor the pressure of the high-pressure module and the low-pressure module accordingly, thereby knowing whether the pressure exceeds the normal range, grasping the battery pressure situation, and ensuring the safety of the battery. At the same time, it is only necessary to design pressure sensors 10 corresponding to the high-temperature zone module and the low-temperature zone module, which can relatively reduce the number of pressure sensors 10 and reduce costs.

[0062] An embodiment of the present invention provides a vehicle comprising the solid-state battery described above.

[0063] In this embodiment, since the vehicle includes the solid-state battery as described above, it has all the beneficial effects brought about by all the above-mentioned solid-state battery embodiments, which will not be described one by one here.

[0064] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
