Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection, and in particular to a temperature detection device. Background Art

[0002] With the rapid development of new energy technologies, energy storage battery systems have been widely used in electric vehicles, energy storage power stations, and other fields. As a key core component, the performance and safety of the battery system are directly related to the operational efficiency and reliability of the entire device. Temperature, as a key variable affecting battery performance and safety, is particularly important to monitor and manage. Excessively high temperatures can lead to decreased battery performance, shortened lifespan, and even serious safety issues such as thermal runaway. Therefore, real-time and accurate monitoring of the internal temperature of the battery system is crucial.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0037] This embodiment provides a temperature detection device, such as Figure 1 and Figure 2 As shown, it includes a fixing frame 1, a mounting frame 2, a lifting mechanism 3, a sliding frame 4 and a first sensor 5;

[0038] The mounting frame 2 is slidably engaged with the fixed frame 1 in the vertical direction. The mounting frame 2 is provided with at least one sliding frame 4. The position of each sliding frame 4 relative to the mounting frame 2 in the horizontal direction is adjustable. The first sensors 5 are mounted on the sliding frames 4 in a one-to-one correspondence.

[0039] The lifting mechanism 3 is installed between the mounting frame 2 and the fixing frame 1 to adjust the height of the mounting frame 2 relative to the fixing frame 1 .

[0040] During use, the height of the mounting frame 2 relative to the fixed frame 1 can be adjusted using the lifting mechanism 3, thereby changing the height of each first sensor 5. The horizontal position of each first sensor 5 relative to the battery can also be changed by changing the horizontal position of the sliding frame 4 relative to the mounting frame 2. The temperature detection device provided in this embodiment not only expands the temperature measurement range but also enables dynamic monitoring of different battery locations, enabling timely detection of local temperature anomalies, more comprehensively reflecting the temperature distribution within the battery system, and improving the real-time and dynamic nature of temperature detection.

[0041] The position of the sliding frame 4 relative to the mounting frame 2 can be adjusted by screws, which pass through the sliding frame 4 and are connected to the mounting frame 2. When the screws are tightened, the screws lock the position of the sliding frame 4 relative to the mounting frame 2; when the screws are loosened, the screws release the lock on the position of the sliding frame 4 relative to the mounting frame 2.

[0042] In an optional embodiment, to facilitate personnel operation, such as Figure 2As shown, the sliding frame 4 includes a sliding sleeve 41 and an elastic limit member 42; the sliding sleeve 41 slides with the mounting frame 2 along the first direction, and the mounting frame 2 is provided with a plurality of limit holes 21 along the first direction. The elastic limit member 42 slides with the sliding sleeve 41 along the vertical direction, and the elastic limit member 42 is configured to be stuck in any one of the limit holes 21 under the action of its own elastic force.

[0043] When the position of the sliding sleeve 41 needs to be adjusted, the elastic limiting member 42 can be pulled out by overcoming 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 along the first direction. After the sliding sleeve 41 slides to the appropriate position, the elastic limiting member 42 is released. The elastic limiting member 42 is stuck in the corresponding limiting hole 21 under the action of its own elastic force, locking the position of the sliding sleeve 41.

[0044] The advantage of the above embodiment is that the position of the sliding sleeve 41 can be locked and unlocked by releasing and pulling out the elastic limiter 42. The operation is simple and does not require the use of additional auxiliary tools, thereby effectively improving the position adjustment efficiency of the sliding frame 4.

[0045] It should be noted that the first direction can be any direction on the horizontal plane. Figure 1 For example, the first direction is the length direction of the fixing frame 1 .

[0046] In an optional embodiment, if Figure 2 and Figure 3 As shown, the elastic limiter 42 includes a paddle 421, an insert rod 422 and a spring 423. The paddle 421 is connected to one end of the insert rod 422. The spring 423 is sleeved on the outside of the insert rod 422. One end of the spring 423 is connected to the paddle 421, and the other end is connected to the sleeve 41. The insert rod 422 slides with the sleeve 41 in the vertical direction and is configured to be stuck in any limiting hole 21 under the elastic force of the spring 423, so that the detection device can adapt to different battery layouts and temperature measurement requirements, thereby improving the versatility of the device.

[0047] In the natural state, the insertion rod 422 passes through the hole on the sliding sleeve 41 and extends into the limiting hole 21 on the mounting frame 2 under the limit of the elastic force of the spring 423, locking the position of the sliding sleeve 41; when the position of the sliding sleeve 41 needs to be adjusted, the personnel can overcome the elastic force of the spring 423 and pull out the paddle 421, and the paddle 421 drives the insertion rod 422 to withdraw from the inserted limiting hole 21. At this time, the sliding sleeve 41 can be slid along the first direction until the sliding sleeve 41 moves to the appropriate position, and then the paddle 421 can be released.

[0048] The elastic limiting member 42 has a simple structure, and the insertion rod 422 can be reset by the elastic force of the spring, and is easy to process and assemble.

[0049] Specifically, the paddle 421 may be in a sheet shape, one end of which is connected to the insertion rod 422 , and the other end of which is used for a person to hold, making it easier for the person to operate.

[0050] In an optional embodiment, if Figure 2 As shown, the sliding frame 4 also includes a support plate 43, a pressure plate 44 and an adjustment assembly 45; the support plate 43 is fixedly connected to the sliding sleeve 41, the pressure plate 44 slides with the sliding sleeve 41 in the vertical direction, and a first mounting cavity for clamping the first sensor 5 is formed between the pressure plate 44 and the support plate 43, and the adjustment assembly 45 is installed between the sliding sleeve 41 and the pressure plate 44 to adjust the distance between the pressure plate 44 and the support plate 43.

[0051] When installing the first sensor 5, you can first increase the distance between the pressure plate 44 and the support plate 43 through the adjustment component 45. At this time, the space of the first installation cavity is larger. Then, extend the first sensor 5 into the first installation cavity. After the first sensor 5 is extended to a suitable depth, reduce the distance between the pressure plate 44 and the support plate 43 through the adjustment component 45. The pressure plate 44 and the support plate 43 clamp the first sensor 5 to complete the installation of the first sensor 5.

[0052] The above embodiment can adjust the size of the first installation cavity, facilitate the installation of the first sensor 5 , and can adapt to first sensors 5 of different sizes, thereby improving the versatility and flexibility of the sliding frame 4 .

[0053] The first sensor 5 may be a contact temperature sensor.

[0054] Specifically, the sliding sleeve 41 may include a frame 411 and a plurality of guide columns 412. The frame 411 may be a rectangular frame structure, which is mounted on the outside of the mounting frame 2 and slides with the mounting frame 2 along a first direction. Both ends of each guide column 412 are connected to the frame 411 through a mounting seat, and each guide column 412 extends in a vertical direction. The pressure plate 44 slides with each guide column 412 in a vertical direction.

[0055] Reference Figure 2 The sliding sleeve 41 includes two guide columns 412 , which are distributed on both sides of the adjustment component 45 to ensure the stability of the movement of the pressure plate 44 .

[0056] The pressure plate 44 includes a plate body 441, a connecting rod 442 and a sliding plate 443. A first mounting cavity is formed between the plate body 441 and the support plate 43. The connecting rod 442 is connected between the plate body 441 and the sliding plate 443. The sliding plate 443 slides with the guide column 412 in the vertical direction, and the sliding plate 443 is connected to the adjustment assembly 45.

[0057] It should be noted that any structure capable of adjusting the distance between the pressing plate 44 and the supporting plate 43 can be the adjustment assembly 45 mentioned in the above embodiment. For example, the adjustment assembly 45 can be a structure that performs linear motion, such as a pneumatic cylinder, a hydraulic cylinder, or a linear motor. It can also include a screw, or a structure that includes a gear and a rack that convert the rotation of the power source into linear motion.

[0058] In an optional embodiment, if Figure 2 As shown, the adjustment assembly 45 includes a first screw 451 , the first screw 451 and the sliding sleeve 41 are rotationally engaged through a bearing, and the sliding plate 443 in the pressure plate 44 is threadedly engaged with the first screw 451 .

[0059] Since the sliding plate 443 is slidably engaged with the guide post 412 along the vertical direction, when the first screw 451 is rotated, the first screw 451 can drive the entire pressing plate 44 to slide relative to the guide post 412 .

[0060] Compared with electric drive, the above-mentioned adjustment component has the characteristics of low cost and is also easy for personnel to operate.

[0061] To facilitate operation by personnel, the adjustment component 45 also includes a first knob 452 connected to the end of the first screw 451. The setting of the first knob 452 makes it easy for personnel to rotate the first screw 451 to achieve rapid adjustment of the height of the pressure plate 44.

[0062] In an optional embodiment, if Figure 4 and Figure 5 As shown, the pressure plate 44 is also rotatably connected to the limiting member 46 through a bearing. The limiting member 46 passes through the pressure plate 44 and extends into the first mounting cavity between the pressure plate 44 and the support plate 43. A cam 461 is provided at one end of the limiting member 46 located in the first mounting cavity, and a hand-held portion 462 is provided at one end of the limiting member 46 located outside the first mounting cavity.

[0063] When the first sensor 5 is a contact sensor, since the end of the first sensor 5 needs to contact the battery, the battery is often placed inside the mounting frame 2 before each first sensor 5 is installed, so as to accurately control the length of the first sensor 5 extending from the first mounting cavity. However, since the first sensor 5 is generally small in size, after the support plate 43 and the pressure plate 44 clamp the first sensor 5, the length of the first sensor 5 extending from the first mounting cavity is relatively small. This makes it inconvenient for a person to hold the exposed end of the first sensor 5 to adjust the extension length of the first sensor 5.

[0064] The above embodiment can solve the above problem. When installing the first sensor 5, the first sensor 5 can be first extended into the first installation cavity to a deeper distance, and then the handheld part 462 can be held to rotate the limit member 46 and the cam 461 connected to the limit member 46. The cam 461 can push the first sensor 5 out until the first sensor 5 contacts the outer surface of the battery. At this time, the distance between the pressure plate 44 and the support plate 43 can be reduced by adjusting the component 45, and the first sensor 5 can be clamped.

[0065] The above-mentioned limiting member 46 can provide a larger operating space for personnel, ensuring that each first sensor 5 can stably contact the outer surface of the battery after installation, thereby ensuring the accuracy of the detected temperature.

[0066] In order to facilitate the assembly of the limiting member 46, the cam 461 is detachable, and can be specifically detachable through structures such as buckles, pins, and screws.

[0067] In an optional embodiment, if Figure 1 As 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 slides with the guide rod assembly 12 in the vertical direction. The bracket 13 is connected to the base 11, and the bracket 13 is mounted on the outside of the mounting frame 2. The bracket 13 is used to install at least one second sensor 6.

[0068] In the above embodiment, the guide rod assembly 12 can guide the movement of the mounting frame 2. Figure 1 As shown, the guide rod assembly 12 includes multiple guide rods. When the base 11 is a rectangular frame structure, the mounting frame 2 is also a rectangular frame structure. Each corner of the base 11 is connected to a guide rod to ensure the stability of the movement of the mounting frame 2.

[0069] In addition, the bracket 13 is mounted on the outside of the mounting frame 2 to prevent the bracket 13 from interfering with the batteries in the mounting frame 2, thereby ensuring that the batteries have a sufficiently large installation space.

[0070] 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 sensor.

[0071] The above implementation combines infrared and contact temperature sensors to achieve both macroscopic monitoring of the overall temperature of the energy storage battery system and precise measurement of local temperatures. The infrared temperature sensor can quickly detect the overall temperature distribution within the battery compartment, while the contact temperature sensor can accurately measure the temperature of individual cells. This effectively addresses the limited detection range of traditional detection methods, providing a more comprehensive picture of the battery system's temperature status and providing more reliable assurance for safe battery operation.

[0072] In an optional embodiment, if Figure 1 As shown, the position of each sliding frame 4 relative to the mounting frame 2 along the first direction is adjustable. The mounting frame 2 has a concave structure 22 at one end in the first direction. A second mounting cavity is formed between the concave structure 22 and the bracket 13. The lifting mechanism 3 is located in the second mounting cavity. The lifting mechanism 3 is connected between the bracket 13 and the mounting frame 2.

[0073] In the above embodiment, the mounting frame 2 has a concave structure 22 at one end in the first direction, which can form a second mounting cavity for mounting the lifting mechanism 3 between itself and the bracket 13, so that the device is more integrated and can protect the lifting mechanism 3 to prevent leakage of the lifting mechanism 3.

[0074] The optional structure of the lifting mechanism 3 is similar to the optional structure of the adjustment component 45. Any structure that can adjust the height of the mounting frame 2 relative to the fixing frame 1 is acceptable. To save space, no examples are given here one by one.

[0075] In an optional embodiment, if Figure 1 As shown, 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. 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 frame 2 is threadedly engaged with the second screw 32.

[0076] During use, the driver 31 can drive the second screw 32 to rotate, and the second screw 32 drives the mounting frame 2 to rise and fall, so that the first sensor 5 can cover more areas, realize dynamic patrol temperature measurement of different positions of the battery, timely discover local temperature anomalies, and improve the comprehensiveness and dynamism of temperature detection, which is of great significance for preventing safety hazards such as battery thermal runaway.

[0077] In the above embodiment, since the size of the mounting frame 2 is large, multiple sliding frames 4 and multiple first sensors 5 are installed on it, and a large torque is required to rotate the second screw 32. It is more time-saving and labor-saving to drive the second screw 32 to rotate through the driver 31.

[0078] The driver 31 may be, but is not limited to, a motor.

[0079] In an optional embodiment, in order to facilitate the disassembly and assembly of the second sensor 6, as shown in FIG. Figure 6 and Figure 7As shown, 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, the first connecting foot 71 and the second connecting foot 72 are both connected to the opening 731 and are both slidingly matched with the bracket 13; the third screw 8 is rotatably connected to the bracket 13, and the extension 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 that is threadedly matched with the first connecting foot 71 and a second thread that is threadedly matched with the second connecting foot 72, and the rotation direction of the first thread is opposite to that of the second thread.

[0080] During use, the third screw 8 can be rotated. Since the rotation direction of the first thread is opposite to that of the second thread, and the first connecting foot 71 and the second connecting foot 72 are both slidingly matched 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 achieve the clamping and release of the second sensor 6.

[0081] To facilitate operation by personnel, one end of the third screw rod 8 may be connected to a second knob 9 .

[0082] The clamping block 7 and the third screw 8 can quickly clamp and fix the second sensor 6, effectively simplifying the installation and maintenance process, reducing the complexity and cost of the device, and improving work efficiency.

[0083] Specifically, if Figure 7 As shown, the bracket 13 is in an inverted U shape, with both ends connected to the base 11, and a through hole 131 and a slide groove 132 are provided at the top of the bracket 13; the through hole 131 is used for the second sensor 6 to pass through and extend to the space below the bracket 13; the slide groove 132 extends along the first direction, and the first connecting foot 71 and the second connecting foot 72 both slide in cooperation with the slide groove 132.

[0084] The temperature detection device provided in the above embodiment can detect temperature anomalies in the battery system in a timely manner through comprehensive and dynamic temperature detection, thereby avoiding safety issues 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 equipment. In addition, the above temperature detection device can also adapt to energy storage battery systems of different specifications and layouts, and has strong versatility and adaptability. Whether in electric vehicles, energy storage power stations or other scenarios that require battery temperature monitoring, efficient and reliable temperature detection can be achieved, and it has broad application prospects.

[0085] 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 it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
