[0001] This application relates to the field of electrical equipment technology, and more particularly to a temperature measuring device, a battery pack, and electrical equipment. Background Technology

[0002] The battery pack is the energy supply component of electrical equipment. It generates heat during use, and the temperature of the battery pack will rise accordingly. To improve the safety of the battery pack, its temperature needs to be monitored.

[0003] In the existing technology, infrared temperature measuring devices can be used to monitor the temperature of the battery pack.

[0004] However, other components within the battery pack may obstruct the detection area, limiting the installation location of the temperature measuring device. Utility Model Content

[0005] The purpose of this application is to provide a temperature measuring device, a battery pack, and an electrical device, aiming to solve the problem of how to improve the flexibility of the installation position of the temperature measuring device within the battery pack.

[0009] In the above scheme, the reflective surface of the reflector can receive infrared rays generated by the object being tested and reflect them back. The detection element is used to receive the infrared rays reflected by the reflector. Since the first adjustment mechanism can adjust the angle between the reflective surface and the object being tested, when the relative positions of the object being tested and the reflector are fixed, adjusting the angle between the reflective surface of the reflector and the object being tested can adjust the incident angle and reflection angle of the infrared rays generated by the object being tested relative to the reflective surface. This adjusts the position of the infrared reflection area. As long as the detection element is located within the reflection area, it can receive the infrared rays reflected by the reflector, improving the flexibility of the detection element's position arrangement.

Detailed Implementation

[0027] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0028] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0030] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°.

[0031] This application provides an electrical device, which can be a vehicle 1000. The vehicle 1000 can be a pure electric vehicle, a hybrid electric vehicle, etc. The vehicle 1000 can also be a sedan, bus, truck, trailer, etc. This application does not specifically limit the type of vehicle 1000.

[0032] It should be noted that the electrical equipment can be not only a vehicle 1000, but also an airplane, a ship, etc. This application embodiment uses a vehicle 1000 as the electrical equipment for illustration.

[0033] In some embodiments, see Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle 1000 provided in an embodiment of this application. The vehicle 1000 includes a body 100 and wheels 200. The wheels 200 are connected to the body 100 and located below the body 100 for contacting the road surface. When the wheels 200 roll on the road surface, they can drive the vehicle 1000 to move.

[0034] In some embodiments, see Figure 1 and Figure 2 The vehicle 1000 also includes a battery pack 300, which is connected to the body 100 and is used to provide energy to the vehicle 1000 so that the vehicle 1000 can drive.

[0035] It should be noted that the battery pack 300 can be used not only in vehicles 1000, but also in other electrical equipment, such as airplanes and ships.

[0036] In some embodiments, see Figure 2 In order to improve the safety performance of the battery pack 300, a temperature measuring device 10 can be installed inside the battery pack 300 to detect the temperature of the battery pack 300 and prevent the battery pack 300 from overheating and causing safety hazards.

[0037] It should be noted that the temperature measuring device 10 can be installed not only in the battery pack 300, but also in other equipment to detect the temperature of components within the equipment. For example, the temperature measuring device 10 can be installed in a transformer to detect the temperature of relevant components within the transformer.

[0038] In some implementations, see Figure 2 , Figure 3 and Figure 4 The temperature measuring device 10 includes a reflector 1, a detector 2, and a first adjustment mechanism 3. The reflector 1 has a reflective surface 111, which is adapted to face the detector 2 to receive infrared radiation generated by the detector 2. The detector 2 is located on the side facing the reflective surface 111 and has a receiving surface 21 adapted to receive the infrared radiation reflected by the reflective surface 111, so that the detector 2 can detect the temperature of the detector 2. The reflector 1 is connected to the first adjustment mechanism 3, which can adjust the angle between the reflective surface 111 and the receiving surface 21.

[0039] In the above scheme, the reflective surface 111 of the reflector 1 can receive the infrared rays generated by the tested component 2 and reflect them. The tested component 2 is used to receive the infrared rays reflected by the reflector 1. Since the first adjustment mechanism 3 can adjust the angle of the reflective surface 111 relative to the tested component 2, when the relative positions of the tested component 2 and the reflector 1 are fixed, adjusting the angle of the reflective surface 111 of the reflector 1 relative to the tested component 2 can adjust the incident angle and reflection angle of the infrared rays generated by the tested component 2 relative to the reflective surface 111, thereby adjusting the position of the infrared reflection area. As long as the tested component 2 is located within the reflection area, it can receive the infrared rays reflected by the reflector 1, improving the flexibility of the position arrangement of the tested component 2.

[0040] In some examples, the reflecting surface 111 of the reflector 1 is a plane.

[0041] In some examples, the reflecting surface 111 of the reflector 1 is a smooth mirror surface.

[0042] In some examples, the detection element 2 includes an infrared temperature sensor having a receiving surface 21 that measures the temperature of the detection element 2 by receiving infrared light reflected from the reflecting surface 111.

[0043] In some examples, the detection element 2 can be a thermal infrared temperature sensor.

[0044] In other examples, the detection element 2 can be a photoelectric infrared temperature sensor.

[0045] In some examples, the number of reflectors 1 can be one.

[0046] In other examples, the number of reflectors 1 can also be multiple, such as two or three, so that the infrared rays of the detected object 2 can be reflected multiple times by the reflective surfaces 111 of multiple reflectors 1, so that the receiving surface 21 of the detected object 2 can receive the reflected infrared rays.

[0047] It should be noted that when the temperature measuring device 10 is located in the battery pack 300, the component being tested 2 can be a battery cell or an electrical connector 5 inside the battery pack 300.

[0048] The position of the detected component 2 within the battery pack 300 is fixed. When space constraints prevent the installation of the detected component 2 from being obstructed by reinforcing ribs or other obstructing elements 7, the infrared radiation generated by the detected component 2 can be reflected back to the detected component 2 by the reflective surface 111 of the reflector 1. If the angle of the reflective surface 111 of the reflector 1 relative to the detected component 2 cannot be adjusted, the relative position of the reflective surface 111 and the detected component 2 is fixed, and the infrared radiation reflection area is also fixed. The detected component 2 can only be placed within a fixed area to ensure that it can receive the infrared radiation reflected by the reflective surface 111. This results in limited installation position of the detected component 2 and poor versatility when the temperature measuring device 10 is applied to different models of battery packs 300.

[0049] This application allows for adjustment of the infrared radiation's incident and reflection angles on the reflective surface 111 relative to the detected component 2 by adjusting the angle of the reflective surface 111 of the reflector 1. This adjustment, in turn, adjusts the reflection area of ​​the reflected infrared radiation, thereby increasing the flexibility of the detected component 2's placement and enhancing the versatility of the temperature measuring device 10 in different signal battery packs 300. The installation position of the detected component 2 can be adjusted by changing the angle of the reflective surface 111 of the reflector 1 relative to the detected component 2, taking into account the internal space of different battery packs 300.

[0050] In some implementations, see Figure 2 and Figure 3 The first adjustment mechanism 3 includes a first support member 31, and the reflector 1 is rotatably connected to the first support member 31.

[0051] In the above scheme, the reflector 1 is rotatably connected to the first support 31. The angle of the reflector 111 relative to the first support 31 can be adjusted by driving the reflector 1 to rotate relative to the first support 31, thereby adjusting the angle of the reflector 111 relative to the detected object 2.

[0052] In some examples, the first support 31 is used for fixed connection with the housing 6 of the battery pack 300. Since the object being tested 2 is also connected to the housing 6 of the battery pack 300, the angle of the reflective surface 111 relative to the object being tested 2 can be adjusted by adjusting the angle of the reflective surface 111 relative to the object being tested 2.

[0053] For example, the first support member 31 and the housing 6 can be connected by means of screws or adhesive.

[0054] In some examples, the reflector 1 can be rotatably connected to the first support 31 via a pivot.

[0055] In other examples, the reflector 1 can be rotatably connected to the first support 31 via a universal swivel joint.

[0056] In some implementations, see Figure 2 and Figure 3 The first support member 31 includes a support member body and a first guide portion 314 disposed on the support member body. The reflector 1 includes a reflector body 11 and a second guide portion disposed on the reflector body 11. The reflector body 11 is provided with a reflective surface 111. The reflector body 11 is rotatably connected to the support member body. The first guide portion 314 cooperates with the second guide portion to guide the reflector body 11.

[0057] In the above scheme, the first guide part 314 of the support body and the second guide part of the reflector body 11 cooperate to guide the rotation of the reflector 1, which can improve the accuracy of the angle adjustment of the reflector surface 111 of the reflector 1, thereby improving the stability of the infrared rays reflected by the reflector surface 111 received by the detector 2.

[0058] In some examples, the first guide portion 314 may be integrally formed with the support body.

[0059] In other examples, the first guide portion 314 may be detachably connected to the support body.

[0060] In some examples, the second guide portion can be integrally formed with the reflector body 11.

[0061] In other examples, the second guide portion can be detachably connected to the reflector body 11.

[0062] In some implementations, see Figure 2 and Figure 3 One of the first guide portion 314 and the second guide portion includes a first slide groove, and the other of the first guide portion 314 and the second guide portion includes a protrusion located in the first slide groove and capable of sliding in the first slide groove.

[0063] In the above scheme, the first guide part 314 and the second guide part cooperate with the first sliding groove through the protrusion. The relative sliding of the protrusion and the first sliding groove enables the reflector body 11 to rotate relative to the support body. The structure is simple and easy to adjust.

[0064] In some examples, the first guide portion 314 includes a first groove, and the second guide portion includes a protrusion connected to the reflector body 11. The reflector body 11 slides along the first groove with the protrusion, thereby enabling the reflector body 11 to rotate relative to the support body.

[0065] In other examples, the first guide portion 314 includes a protrusion connected to the support body, and the second guide portion includes a first groove disposed on the reflector body 11. The reflector body 11 slides relative to the protrusion along the first groove, thereby enabling the reflector body 11 to rotate relative to the support body.

[0066] In some embodiments, one end of the reflector body 11 is rotatably connected to the support body, and the second guide portion is located at the other end of the reflector body 11.

[0067] In the above scheme, since one end of the reflector body 11 is rotatably connected to the support body, and the second guide part is located at the other end of the reflector body 11, when the second guide part is pushed, the reflector body 11 can move along the first guide part 314 with the second guide part, realizing the rotation of the reflector body 11 relative to the support body. The structure is simple and easy to adjust.

[0068] In some other embodiments, the support body includes a first hinge portion, and the reflector body 11 includes a second hinge portion, which is located at the center of the reflector body 11. The first hinge portion and the second hinge portion are hinged together. Since the first hinge portion and the second hinge portion can rotate relative to each other, the reflector body 11 can rotate relative to the support body.

[0069] In some implementations, see Figure 2 and Figure 3 The first adjustment mechanism 3 also includes a first locking member 32, which is detachably connected to the reflector 1 and detachably connected to the first support member 31, for locking the reflector 1 and the first support member 31.

[0070] In the above scheme, after adjusting the angle of the reflective surface 111 of the reflector 1 relative to the first support 31, the position of the reflector 1 and the first support 31 is fixed by the first locking member 32, which can prevent the reflector 1 from rotating relative to the first support 31 during use and provide stability to the first adjustment mechanism 3.

[0071] In some other embodiments, after the positions of the first locking member 32 and the first support member 31 are adjusted, their relative positions can be fixed by means of bonding or other methods.

[0072] In some implementations, see Figure 2 and Figure 3 The first guide portion 314 includes a first slide groove, and the second guide portion includes a protrusion located within the first slide groove and capable of sliding within the first slide groove. The protrusion is provided with an external thread, and the first locking member 32 is provided with a threaded hole. The external thread of the protrusion is located within the threaded hole and is threadedly connected to the first locking member 32. The first locking member 32 is connected to the first support member 31.

[0073] In the above scheme, the protrusion is provided with an external thread, and the first locking member 32 is provided with a threaded hole, with the external thread engaging with the threaded hole. When the first locking member 32 is rotated in the first direction, with the engagement of the external thread and the threaded hole, the first locking member 32 moves towards the reflector body 11, thereby fixing the reflector body 11 to the support body. When the first locking member 32 is rotated in the second direction, with the engagement of the external thread and the threaded hole, the first locking member 32 moves away from the reflector body, allowing the reflector body 11 to rotate relative to the support body, thereby adjusting the angle of the reflective surface 111 relative to the support body. The locking structure of the first locking member 32 is simple, facilitating locking and adjustment operations. The first and second directions are opposite.

[0074] In some examples, the protrusion is located within the first groove of the first support member 31, and the reflector body 11 and the first locking member 32 are located on opposite sides of the first groove. When the first locking member 32 moves toward the reflector body 11, the first locking member 32 and the reflector body 11 will clamp the support member body to fix the reflector body 11 to the support member body.

[0075] In some other embodiments, the first locking member 32 is integrally formed with the protrusion. The first locking member 32 and the reflector body 11 are respectively located on both sides of the first slide groove. The protrusion passes through the first slide groove, and the side of the protrusion facing the reflector body 11 has an external thread. The reflector body 11 has a threaded hole, and the external thread engages with the threaded hole. When the first locking member 32 is rotated, the protrusion rotates together with the first locking member 32. With the engagement of the external thread and the threaded hole, when the first locking member 32 moves toward the reflector body 11, it fixes the reflector body 11 and the support body. When the first locking member 32 moves away from the reflector body 11, the reflector body 11 can rotate relative to the support body to adjust the angle of the reflective surface 111 relative to the support body.

[0076] In some implementations, see Figure 2 and Figure 3 The support body includes a base 311 and a first adjustment part 312 and a second adjustment part 313 connected to opposite sides of the base 311. The base 311, the first adjustment part 312 and the second adjustment part 313 form an accommodating space. The reflector 1 is disposed in the accommodating space and is rotatably connected to the first adjustment part 312 and the second adjustment part 313 respectively.

[0077] In the above scheme, the reflector 1 is disposed in the accommodating space formed by the base 311, the first adjustment part 312, and the second adjustment part 313, and the reflector 1 is connected to both the first adjustment part 312 and the second adjustment part 313, which can improve the stability of the connection between the reflector 1 and the first support 31.

[0078] In some examples, the base 311 is integrally formed with the first adjustment part 312 and the second adjustment part 313.

[0079] In other examples, the first adjustment part 312 and the second adjustment part 313 are detachably connected to the base 311.

[0080] In some examples, the base 311 is used to connect to the housing 6 of the battery pack 300.

[0081] In some examples, the base 311 may be a flat plate structure.

[0082] In some implementations, see Figure 2 and Figure 3 The first guide portion 314 is provided on the first adjustment portion 312 and / or the second adjustment portion 313.

[0083] In the above scheme, the reflector 1, the first adjustment part 312, and the second adjustment part 313 can all be connected to the second guide part through the first guide part 314. The structure is simple and improves the stability of the connection between the reflector 1 and the first support part 31.

[0084] In some examples, the first guide portion 314 is provided on the first adjustment portion 312.

[0085] In other examples, the first guide portion 314 is located on the second adjustment portion 313.

[0086] In some other examples, the first adjustment part 312 and the second adjustment part 313 are each provided with a first guide part 314, and the two sides of the reflector body 11 are each provided with a second guide part, and the two second guide parts cooperate with one first guide part 314 respectively.

[0087] In some implementations, see Figure 2 , Figure 3 and Figure 4 The temperature measuring device 10 also includes a second adjustment mechanism 4, and the detection element 2 is movably connected to the second adjustment mechanism 4 to adjust the angle between the receiving surface 21 and the reflecting surface 111.

[0088] In the above scheme, the detection element 2 is movably connected to the second adjustment mechanism 4, and the angle between the receiving surface 21 of the detection element 2 and the reflecting surface 111 of the reflector 1 can be adjusted by the second adjustment mechanism 4. By adjusting the angle between the receiving surface 21 and the reflecting surface 111, the receiving surface 21 can be directly facing the reflecting surface 111, thereby increasing the receiving surface area of ​​the receiving surface 21 and improving the detection accuracy of the detection element 2.

[0089] It should be noted that the structure of the second adjustment mechanism 4 can be the same as that of the first adjustment mechanism 3 described above. In this embodiment, the structure of the second adjustment mechanism 4 will not be described in detail, but only the connection method between the detection element 2 and the second adjustment mechanism 4 will be briefly described.

[0090] The second adjustment mechanism 4 includes a second support member 41, and one end of the detection member 2 is rotatably connected to the second support member 41 so that the receiving surface 21 of the detection member 2 can rotate relative to the second support member 41, thereby adjusting the angle of the receiving surface 21 relative to the reflecting surface 111.

[0091] The second adjustment mechanism 4 also includes a second locking member 42. The second support member 41 is provided with a second slide groove 411. The detection member 2 can slide along the second slide groove 411. The second locking member 42 is used to lock the detection member 2 and the second support member 41.

[0092] In some implementations, see Figure 2 , Figure 3 and Figure 4 The battery pack 300 also includes a battery cell, a housing 6, and an electrical connector 5. The battery cell is located inside the housing 6 and is electrically connected to the electrical connector 5, which is connected to the housing 6.

[0093] The reflector 1 of the temperature measuring device 10 is connected to the housing 6, and the reflective surface 111 of the reflector 1 faces the electrical connector 5. The detection element 2 of the temperature measuring device 10 is connected to the housing 6 and is located on the side facing the reflective surface 111.

[0094] In the above scheme, the temperature measuring device 10 is installed inside the housing 6 of the battery pack 300, and the temperature of the battery pack 300 is detected by detecting the temperature of the electrical connector 5 that is electrically connected to the battery cell. Since the temperature of the electrical connector 5 that is electrically connected to the battery cell is usually higher than the temperature of the battery cell, detecting the temperature of the electrical connector 5 can prevent the electrical connector 5 from causing safety hazards due to excessive temperature.

[0095] In some examples, the reflector 1 is connected to the housing 6 of the battery pack 300 via the base 311 of the first adjustment mechanism 3.

[0096] In some examples, the detection element 2 is connected to the housing 6 of the battery pack 300 via the base 311 of the second adjustment mechanism 4.

[0097] In some examples, electrical connector 5 can be a high-voltage connector.

[0098] In other examples, electrical connector 5 may be a high-voltage wiring harness.

[0099] In some examples, the electrical connector 5 can be connected to the housing 6 by welding, bonding, or other methods.

[0100] To facilitate understanding of the temperature measuring device 10 provided in the embodiments of this application, the following is in conjunction with... Figure 5 , Figure 6 and Figure 7 The principle and application scenarios of the temperature measuring device 10 provided in the embodiments of this application will be explained.

[0101] See Figure 5 , Figure 5 An obstruction 7 exists between the tested component 2 and the detection component 2, both located within the battery pack 300, preventing the infrared radiation generated by the tested component 2 from being directly transmitted to the detection component 2. The obstruction 7 can be a reinforcing rib or similar component within the battery pack 300.

[0102] At this time, a reflector 1 can be set inside the battery pack 300. The reflector 1 reflects the infrared light generated by the detector 2 back to the detector 2. In order to improve the flexibility of the position setting of the detector 2, the reflector 1 can be connected to the first adjustment mechanism 3. The first adjustment mechanism 3 adjusts the reflection area of ​​the reflective surface 111 of the reflector 1 so that the detector 2 is located in the reflection area and can successfully receive the infrared light reflected by the reflector 1.

[0103] See Figure 6 , Figure 6 Temperature measuring device 10 and Figure 5 The difference in the temperature measuring device 10 is that, Figure 6 Two reflectors 1 are set in the temperature measuring device 10. Since the blocking range of the blocking component 7 is different, two reflectors 1 can be set in the temperature measuring device 10 so that the infrared light generated by the detected component 2 is reflected twice and then reflected to the detection component 2, and then the temperature of the detected component 2 is detected by the detection component 2.

[0104] See Figure 7 , Figure 7 Medium temperature measuring device 10 and Figure 5 and Figure 6 The difference in the temperature measuring device 10 is that, Figure 7 Three reflectors 1 are set in the middle. Depending on the different blocking range of the blocking component 7, three reflectors 1 can be set in the side enclosure device so that the infrared light generated by the tested component 2 is reflected to the testing component 2 after three reflections, and then the temperature of the tested component 2 is detected by the testing component 2.

[0105] As can be seen from the above embodiments, the temperature measuring device 10 of this application can flexibly set the number of reflectors 1 according to the blocking situation of the blocking member 7, and then adjust the incident angle and reflection angle of infrared rays on the reflective surface 111 of the reflector 1 through the first adjustment mechanism 3, so that the infrared rays generated by the detected member 2 can be reflected to the detected member 2 after multiple reflections, thereby improving the flexibility of the position setting of the temperature measuring device 10.

[0106] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0107] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
