[0021] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0023] This embodiment aims to provide a temperature detection device, as Figure 1 and Figure 2 shown, including a fixed frame 1, a mounting frame 2, a lifting mechanism 3, a sliding frame 4, and a first sensor 5; The mounting frame 2 is slidably engaged with the fixed frame 1 in the vertical direction. At least one sliding frame 4 is provided on the mounting frame 2, and the positions of the respective sliding frames 4 relative to the mounting frame 2 are adjustable in the horizontal direction. The first sensors 5 are correspondingly mounted on the sliding frames 4; The lifting mechanism 3 is installed between the mounting frame 2 and the fixed frame 1 to adjust the height of the mounting frame 2 relative to the fixed frame 1.

[0024] In use, the height of the mounting frame 2 relative to the fixed frame 1 can be adjusted through the lifting mechanism 3, thereby changing the height of each first sensor 5. Also, by changing the horizontal position of the sliding frame 4 relative to the mounting frame 2, the horizontal position of each first sensor 5 relative to the battery can be changed. The temperature detection device provided in this embodiment not only expands the temperature measurement range but also realizes the dynamic monitoring of different positions of the battery, can timely detect local temperature anomalies, more comprehensively reflect the temperature distribution inside the battery system, and improve the real-time and dynamic performance of temperature detection.

[0025] Among them, the position adjustment of the sliding frame 4 relative to the mounting frame 2 can be achieved by screws. The screws pass through the sliding frame 4 and are connected to the mounting frame 2. When the screws are tightened, the position of the sliding frame 4 relative to the mounting frame 2 is locked; when the screws are loosened, the locking of the position of the sliding frame 4 relative to the mounting frame 2 is released.

[0026] In an alternative embodiment, for the convenience of personnel operation, as Figure 2 shown, the sliding frame 4 includes a sliding sleeve 41 and an elastic limiting member 42; the sliding sleeve 41 is slidably engaged with the mounting frame 2 in the first direction. The mounting frame 2 is provided with a plurality of limiting holes 21 in the first direction. The elastic limiting member 42 is slidably engaged with the sliding sleeve 41 in the vertical direction, and the elastic limiting member 42 is configured to be snapped into any one of the limiting holes 21 under the action of its own elastic force.

[0027] When it is necessary to adjust the position of the sliding sleeve 41, the elastic limiting member 42 can be pulled out against the elastic force, so that the elastic limiting member 42 exits the limiting hole 21. At this time, the sliding sleeve 41 can be slid in the first direction. After the sliding sleeve 41 slides to a suitable position, the elastic limiting member 42 is released, and the elastic limiting member 42 is snapped into the corresponding limiting hole 21 under the action of its own elastic force to lock the position of the sliding sleeve 41.

[0028] The advantage of the above-mentioned embodiment is that the locking and unlocking of the position of the sliding sleeve 41 can be realized by releasing and pulling out the elastic limiting member 42. The operation is simple and no additional auxiliary tools are required, effectively improving the position adjustment efficiency of the sliding frame 4.

[0029] It should be noted that the above-mentioned first direction can be any direction on the horizontal plane. For Figure 1 example, the above-mentioned first direction is the length direction of the fixing frame 1.

[0030] In an alternative embodiment, as Figure 2 and Figure 3 shown, the elastic limiting member 42 includes a dial 421, a plug rod 422 and a spring 423. The dial 421 is connected to one end of the plug rod 422. The spring 423 is sleeved outside the plug rod 422. One end of the spring 423 is connected to the dial 421 and the other end is connected to the sliding sleeve 41. The plug rod 422 is slidably matched with the sliding sleeve 41 in the vertical direction and is configured to be inserted into any one of the limiting holes 21 under the elastic force of the spring 423, so that the detection device can adapt to different battery layouts and temperature measurement requirements, improving the versatility of the device.

[0031] In the natural state, the plug rod 422 extends into the limiting hole 21 on the mounting frame 2 through the hole on the sliding sleeve 41 under the limitation of the elastic force of the spring 423 to lock the position of the sliding sleeve 41; when the position of the sliding sleeve 41 needs to be adjusted, the operator can pull out the dial 421 against the elastic force of the spring 423. The dial 421 drives the plug rod 422 to withdraw from the inserted limiting hole 21. At this time, the sliding sleeve 41 can be slid in the first direction until the sliding sleeve 41 moves to a suitable position, and then the dial 421 can be released.

[0032] The structure of the above-mentioned elastic limiting member 42 is simple. The reset of the plug rod 422 can be realized by the elastic force of the spring, and it is easy to process and assemble.

[0033] Specifically, the dial 421 can be sheet-shaped, with one end connected to the plug rod 422 and the other end for the operator to hold, which is more convenient for the operator to operate.

[0034] In an alternative embodiment, as Figure 2 shown, the sliding frame 4 further includes a support plate 43, a pressing plate 44 and an adjusting assembly 45; the support plate 43 is fixedly connected to the sliding sleeve 41, the pressing plate 44 is slidably matched with the sliding sleeve 41 in the vertical direction, and a first installation cavity for clamping the first sensor 5 is formed between the pressing plate 44 and the support plate 43. The adjusting assembly 45 is installed between the sliding sleeve 41 and the pressing plate 44 to adjust the distance between the pressing plate 44 and the support plate 43.

[0035] When installing the first sensor 5, the distance between the pressing plate 44 and the supporting plate 43 can be first increased by adjusting the adjusting component 45. At this time, the space of the first installation cavity is relatively large. Then, the first sensor 5 is inserted into the first installation cavity. After the first sensor 5 is inserted to an appropriate depth, the distance between the pressing plate 44 and the supporting plate 43 is decreased by adjusting the adjusting component 45, and the pressing plate 44 and the supporting plate 43 clamp the first sensor 5 to complete the installation of the first sensor 5.

[0036] The above-described embodiment can adjust the size of the first installation cavity, facilitate the installation of the first sensor 5, and can adapt to the first sensors 5 of different sizes, improving the versatility and flexibility of the sliding frame 4.

[0037] Among them, the first sensor 5 can be a contact temperature measurement sensor.

[0038] Specifically, the sliding sleeve 41 can include a frame 411 and a plurality of guide posts 412. The frame 411 can be a rectangular frame structure, sleeved outside the mounting frame 2 and slidably cooperating with the mounting frame 2 in the first direction. Both ends of each guide post 412 are connected to the frame 411 through a mounting seat, and each guide post 412 extends in the vertical direction. The pressing plate 44 slidably cooperates with each guide post 412 in the vertical direction.

[0039] Refer to Figure 2 , the sliding sleeve 41 includes two guide posts 412, and the guide posts 412 are distributed on both sides of the adjusting component 45 to ensure the stability of the movement of the pressing plate 44.

[0040] The pressing plate 44 includes a plate body 441, a connecting rod 442, and a sliding plate 443. A first installation cavity is formed between the plate body 441 and the supporting plate 43. The connecting rod 442 is connected between the plate body 441 and the sliding plate 443. The sliding plate 443 slidably cooperates with the guide posts 412 in the vertical direction, and the sliding plate 443 is connected to the adjusting component 45.

[0041] It should be noted that any structure that can adjust the distance between the pressing plate 44 and the supporting plate 43 can be the adjusting component 45 mentioned in the above embodiment. For example, the adjusting component 45 can be a structure that makes a linear motion such as a pneumatic cylinder, a hydraulic cylinder, or a linear motor, or can include a screw rod, or can include a structure in which a gear and a rack cooperate to convert the rotation of a power source into a linear motion.

[0042] In an alternative embodiment, as Figure 2 shown, the adjusting component 45 includes a first screw rod 451. The first screw rod 451 is rotatably cooperated with the sliding sleeve 41 through a bearing, and the sliding plate 443 in the pressing plate 44 is threadedly cooperated with the first screw rod 451.

[0043] Since the sliding plate 443 is in sliding fit with the guide post 412 in the vertical direction, when the first screw 451 is rotated, the first screw 451 can drive the pressing plate 44 to slide relative to the guide post 412 as a whole.

[0044] The above-mentioned adjusting assembly has the characteristics of low cost compared with electric drive, and is also convenient for personnel to operate.

[0045] To be more convenient for personnel to operate, the adjusting assembly 45 further includes a first knob 452 connected to the end of the first screw 451. The setting of the first knob 452 is convenient for personnel to rotate the first screw 451 to quickly adjust the height of the pressing plate 44.

[0046] In an alternative embodiment, as Figure 4 and Figure 5 shown, the pressing plate 44 is also rotatably connected with a limiting member 46 through a bearing. The limiting member 46 penetrates through the pressing plate 44 and extends into the first installation cavity between the pressing plate 44 and the supporting plate 43. A cam 461 is provided at one end of the limiting member 46 located in the first installation cavity, and a handheld portion 462 is provided at one end of the limiting member 46 located outside the first installation cavity.

[0047] When the first sensor 5 is a contact sensor, since the end of the first sensor 5 needs to be in contact with the battery, the battery is often placed inside the mounting bracket 2, and then each first sensor 5 is installed to facilitate precise control of the length of the first sensor 5 extending out of the first installation cavity. Since the size of the first sensor 5 is usually relatively small, after the supporting plate 43 and the pressing plate 44 clamp the first sensor 5, the length of the first sensor 5 exposed out of the first installation cavity is small, so it is not convenient for personnel to hold the exposed end of the first sensor 5 to adjust the extending length of the first sensor 5.

[0048] The above-mentioned embodiment can solve the above problems. When installing the first sensor 5, the first sensor 5 can be first inserted into the first installation cavity at a relatively deep distance, and then the handheld portion 462 is held to rotate the limiting member 46 and the cam 461 connected to the limiting member 46. The cam 461 can push out the first sensor 5 until the first sensor 5 contacts the outer surface of the battery. At this time, the distance between the pressing plate 44 and the supporting plate 43 is reduced through the adjusting assembly 45, and the first sensor 5 is clamped.

[0049] The above-mentioned limiting member 46 can provide a larger operating space for personnel, ensure that each first sensor 5 can stably contact the outer surface of the battery after installation, and thus ensure the accuracy of the detected temperature.

[0050] To facilitate the assembly of the limiting member 46, the cam 461 is detachable, and can be specifically realized as detachable through structures such as buckles, pins, and screws.

[0051] In an alternative embodiment, as Figure 1As shown, the fixing frame 1 includes a base 11, a guide rod assembly 12, and a bracket 13. The guide rod assembly 12 is connected to the base 11. The mounting frame 2 is slidably engaged with the guide rod assembly 12 in the vertical direction. The bracket 13 is connected to the base 11 and is disposed outside the mounting frame 2. The bracket 13 is used to mount at least one second sensor 6.

[0052] In the above embodiment, the guide rod assembly 12 can guide the movement of the mounting frame 2. As Figure 1 shown, the guide rod assembly 12 includes multiple guide rods. When the base 11 has a rectangular frame structure, the mounting frame 2 also has a rectangular frame structure. One guide rod is connected to each corner of the base 11 to ensure the stability of the movement of the mounting frame 2.

[0053] In addition, the bracket 13 is disposed outside the mounting frame 2 to avoid interference of the bracket 13 with the battery inside the mounting frame 2 and ensure that the battery has a sufficiently large mounting space.

[0054] Finally, the second sensor 6 can cooperate with the first sensor 5 to detect the temperature of the battery. The second sensor 6 can be an infrared temperature measurement sensor.

[0055] The above embodiment combines an infrared temperature measurement sensor and a contact temperature measurement sensor to achieve macroscopic monitoring of the overall temperature of the energy storage battery system and precise measurement of the local temperature. The infrared temperature measurement sensor can quickly detect the overall temperature distribution inside the battery box, while the contact temperature measurement sensor can accurately measure the temperature of a single battery, effectively solving the problem of limited detection range of traditional detection methods, being able to more comprehensively reflect the temperature state of the battery system, and providing a more reliable guarantee for the safe operation of the battery.

[0056] In an alternative embodiment, as Figure 1 shown, the positions of the respective sliding frames 4 are adjustable relative to the mounting frame 2 in the first direction. One end of the mounting frame 2 in the first direction has a concave structure 22. A second installation cavity is formed between the concave structure 22 and the bracket 13. The lifting mechanism 3 is located in the second installation cavity. The lifting mechanism 3 is connected between the bracket 13 and the mounting frame 2.

[0057] In the above embodiment, one end of the mounting frame 2 in the first direction has a concave structure 22, which can form a second installation cavity for installing the lifting mechanism 3 between itself and the bracket 13, making the device more integrated, and at the same time being able to protect the lifting mechanism 3 and prevent it from leaking out.

[0058] The optional structure of the lifting mechanism 3 is similar to the optional structure of the adjustment assembly 45. Any structure that can adjust the height of the mounting frame 2 relative to the fixing frame 1 is acceptable. For the sake of brevity, no further examples will be given here.

[0059] In an alternative embodiment, asFigure 1 As shown in the figure, the lifting mechanism 3 includes a driver 31 and a second screw 32. The driver 31 is installed on the bracket 13. One end of the second screw 32 is rotatably engaged with the bracket 13 through a bearing, and the other end of the second screw 32 is connected to the driver 31. The driver 31 is configured to drive the second screw 32 to rotate, and the mounting bracket 2 is in threaded engagement with the second screw 32.

[0060] During use, the driver 31 can drive the second screw 32 to rotate. The second screw 32 drives the mounting bracket 2 to move up and down, enabling the first sensor 5 to cover a larger area, realizing dynamic circuit temperature measurement of different positions of the battery, promptly detecting local temperature anomalies, improving the comprehensiveness and dynamics of temperature detection, and being of great significance for preventing safety hazards such as battery thermal runaway.

[0061] In the above embodiment, since the mounting bracket 2 is relatively large and there are multiple sliding brackets 4 and multiple first sensors 5 installed above it, a relatively large torque is required to rotate the second screw 32. Driving the second screw 32 to rotate by the driver 31 is more time-saving and labor-saving.

[0062] Among them, the driver 31 can be, but is not limited to, a motor.

[0063] In an alternative embodiment, for the convenience of disassembly and assembly of the second sensor 6, as Figure 6 and Figure 7 shown in the figure, the bracket 13 is provided with a clamping block 7 and a third screw 8. The clamping block 7 has a first connecting foot 71, a second connecting foot 72, and a clamping cavity 73 for clamping the second sensor 6. The clamping cavity 73 has an opening 731. Both the first connecting foot 71 and the second connecting foot 72 are connected to the opening 731 and are both slidably engaged with the bracket 13. The third screw 8 is rotatably connected to the bracket 13. The extending direction of the third screw 8 is parallel to the sliding direction of the first connecting foot 71 and the second connecting foot 72. The third screw 8 has a first thread threadedly engaged with the first connecting foot 71 and a second thread threadedly engaged with the second connecting foot 72. The helix direction of the first thread is opposite to that of the second thread.

[0064] During use, the third screw 8 can be rotated. Since the helix direction of the first thread is opposite to that of the second thread, and both the first connecting foot 71 and the second connecting foot 72 are slidably engaged with the bracket 13, the first connecting foot 71 and the second connecting foot 72 will approach or move away from each other during the rotation of the third screw 8, thereby adjusting the size of the opening 731 to realize the clamping and release of the second sensor 6.

[0065] For the convenience of operation by personnel, a second knob 9 can be connected to one end of the third screw 8.

[0066] The above clamping block 7 and the third screw 8 can quickly clamp and fix the second sensor 6, effectively simplifying the installation and maintenance processes, reducing the complexity and cost of the device, and improving work efficiency.

[0067] Specifically, as Figure 7 shown, the bracket 13 is in an inverted U shape, with both ends thereof connected to the base 11. A through hole 131 and a chute 132 are provided at the top of the bracket 13; the through hole 131 is for the second sensor 6 to pass through and extend to the space below the bracket 13; the chute 132 extends along the first direction, and both the first connecting foot 71 and the second connecting foot 72 are slidably engaged with the chute 132.

[0068] The temperature detection device provided by the above embodiment can timely detect temperature anomalies in the battery system through comprehensive and dynamic temperature detection, avoiding safety problems caused by local overheating, such as thermal runaway. This early warning function effectively improves the safety and reliability of the energy storage power battery system, extends the battery life, and provides a strong guarantee for the stable operation of new energy devices. In addition, the above temperature detection device can also adapt to energy storage battery systems with different specifications and layouts, and has strong versatility and adaptability. Whether in electric vehicles, energy storage power stations or other scenarios where battery temperature monitoring is required, efficient and reliable temperature detection can be achieved, and it has a wide range of application prospects.

[0069] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
