Description

Technical Field

[0001] This utility model relates to the field of detector installation, and more specifically, to a detector installation structure for suppressing power battery fires. Background Technology

[0002] The background technology of the installation structure of detectors for suppressing fires in power batteries mainly involves the research and application of battery safety monitoring and fire prevention technologies. Power batteries, especially lithium batteries in electric vehicles and energy storage devices, have a high risk of fire accidents due to their large capacity and high energy density. Lithium batteries may experience thermal runaway under conditions such as overcharging, short circuits, excessive temperature, or other abnormalities, which can lead to fires. To ensure the safe operation of battery systems, real-time detection and timely response to fire hazards are crucial.

[0003] A search revealed that Chinese patent CN209198036U discloses a "Vibration Fixture for a Power Battery of a New Energy Vehicle," which includes a power battery module, a vibration table, and a vibration fixture body mounted on the vibration table. The vibration fixture body includes a base and a frame. The frame includes crossbeams and columns. There are four columns, and each of the four columns has a mounting plate fixed on top. A first detector, a second detector, a third detector, and a fourth detector are mounted clockwise on the four mounting plates, facilitating the installation of various detectors, such as a proportional temperature detector and a combustible gas detector, to monitor the changes in the power battery module during the vibration test. This design is convenient to use. There are four crossbeams, and each of the four crossbeams has a fixing block installed in the middle, facilitating the installation of vibration sensors. This design also ensures that the fixture does not directly contact the power battery module itself, resulting in more accurate vibration data from the power battery module. However, the following drawbacks still exist:

[0004] (1) The above application makes it difficult to quickly install the detector when using it, which makes installation and disassembly more troublesome when maintenance is required.

[0005] The aforementioned applications present difficulties in protecting the installed detectors and absorbing moisture from the air entering the detectors during installation. Prolonged operation in a humid environment can lead to battery malfunctions. Therefore, a detector installation structure for suppressing power battery fires is proposed. Utility Model Content

[0006] The purpose of this invention is to address the current problem that detectors cannot be quickly installed, making installation and disassembly cumbersome when maintenance is required.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The mounting device includes a mounting rod, the top of which is fixedly connected to the bottom of the detector. A slot is provided on the side of the mounting rod. A through slot is provided on the top of the mounting plate. A sliding groove is provided on the inner wall of the mounting plate.

[0017] 1. The installation device allows the first and second locking blocks to engage with the mounting slots to secure the mounting rod, enabling the detector to be installed. During installation, the first and second locking blocks can be pressed into the hollow block, allowing the mounting holes on the detector to be inserted into the hollow block. After the detector is installed, the first and second locking blocks will be reset by a flexible spring, thus allowing for better installation of the detector.

[0018] 2. The protective device ensures that when the force rod moves into the hydraulic cylinder, the hydraulic rod moves outward due to the squeezing force of the force rod. This movement of the hydraulic rod can drive the silicone plate to move, thus protecting the installed detector inside. This allows the detector to absorb moisture from the air entering the detector, ensuring that the detector can work normally in a humid environment and preventing malfunctions caused by the battery's operating environment.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment proposes a detector installation structure for suppressing power battery fires, including a mounting plate 1, a mounting device 2 is provided on the top of the mounting plate 1, a detector 3 is fixedly connected to the top of the mounting device 2, and a mounting handle 4 is fixedly connected to the top of the detector 3.

[0030] The mounting device 2 includes a mounting rod 21, the top of which is fixedly connected to the bottom of the detector 3. A slot 22 is provided on the side of the mounting rod 21. A through slot 23 is provided on the top of the mounting plate 1. A sliding groove 24 is provided on the inner wall of the mounting plate 1. A locking block 25 is slidably connected to the inner wall of the sliding groove 24. A return spring 26 is fixedly connected to the inner wall of the sliding groove 24.

[0031] like Figure 2As shown, in a preferred embodiment, based on the above method, the inner wall of the mounting plate 1 is further provided with a second sliding groove 27, a second locking block 28 is slidably connected to the inner wall of the second sliding groove 27, and a second return spring 29 is fixedly connected to the inner wall of the second sliding groove 27. The end of the second return spring 29 away from the second sliding groove 27 is fixedly connected to the side of the second locking block 28. The function of the second return spring 29 is to drive the second locking block 28 to return to its original position when the mounting rod 21 no longer presses the second locking block 28.

[0032] like Figure 4 As shown, in a preferred embodiment, based on the above method, a hollow block 210 is fixedly connected to the top of the mounting plate 1, a first stop block 211 is slidably connected to the inner wall of the hollow block 210, a second stop block 212 is slidably connected to the inner wall of the hollow block 210, a spring spring 213 is fixedly connected to the back side of the first stop block 211, and the end of the spring spring 213 away from the first stop block 211 is fixedly connected to the front side of the second stop block 212. The function of the first stop block 211 and the second stop block 212 is to better install the detector 3.

[0033] like Figure 2 , Figure 4 As shown, in a preferred embodiment, based on the above method, the mounting rod 21, the first locking block 25, and the second locking block 28 are further designed to be rectangular in shape, and the side sections of the mounting rod 21, the first locking block 25, and the second locking block 28 are inclined. The outer surfaces of the first locking block 25 and the second locking block 28 are located on the displacement trajectory of the mounting rod 21. The number of hollow blocks 210, the first stop block 211, the second stop block 212, and the elastic spring 213 are set to several, and they are symmetrical about each other along the vertical central axis of the mounting plate 1. The function of the outer surfaces of the first locking block 25 and the second locking block 28 being located on the displacement trajectory of the mounting rod 21 is to allow the first locking block 25 and the second locking block 28 to be squeezed when the mounting rod 21 moves.

[0034] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a protective device 5 is further provided on the top of the mounting plate 1. The protective device 5 includes a hydraulic cylinder 51. The bottom of the hydraulic cylinder 51 is fixedly connected to the inside of the mounting plate 1. A force-bearing rod 52 is fixedly connected to the top of the hydraulic cylinder 51. A hydraulic rod 53 is fixedly connected to the side of the hydraulic cylinder 51. A silicone plate 54 is fixedly connected to the side of the hydraulic rod 53. An opening 55 is provided on the top of the silicone plate 54. The function of the silicone plate 54 is to absorb moisture in the air entering the detector 3.

[0035] like Figure 5As shown, in a preferred embodiment, based on the above method, a flexible spring 56 is fixedly connected to the circumferential surface of the force-bearing rod 52. The end of the flexible spring 56 away from the force-bearing rod 52 is fixedly connected to the top of the hydraulic cylinder 51. The function of the flexible spring 56 is to allow the force-bearing rod 52 to be reset by the flexible spring 56 when the mounting rod 21 no longer pushes it.

[0036] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, the top of the force-bearing rod 52 is located on the displacement trajectory of the mounting rod 21. The number of hydraulic rods 53, silicone plates 54 and through-holes 55 are each set to two, and they are symmetrical to each other along the vertical central axis of the mounting plate 1. The purpose of the top of the force-bearing rod 52 being located on the displacement trajectory of the mounting rod 21 is to push the force-bearing rod 52 when the mounting rod 21 moves.

[0037] Specifically, when using this detector mounting device: First, when the device needs to be used, the detector 3 can be installed using the mounting device 2. This is done by aligning the mounting rod 21 with the through groove 23, and then pushing the mounting rod 21 into the through groove 23. Once the mounting rod 21 enters the through groove 23, it will press against the first locking block 25 and the second locking block 28. When the locking blocks 25 and 28 are pressed by the mounting rod 21, they will move into the first sliding groove 24 and the second sliding groove 27 due to their own inclined surfaces and the inclined surface of the mounting rod 21. Thus, when the mounting rod 21 moves the locking groove 22 to the positions of the first locking block 25 and the second locking block 28... The first locking block 25 and the second locking block 28 will be reset by the first reset spring 26 and the second reset spring 29 because they are no longer squeezed by the mounting rod 21. Then the first locking block 25 and the second locking block 28 will be locked into the slot 22 to fix the mounting rod 21, so that the detector 3 can be installed. During installation, the first blocking block 211 and the second blocking block 212 can be pressed into the hollow block 210, so that the mounting hole on the detector 3 can be inserted into the hollow block 210. After the detector 3 is installed, the first blocking block 211 and the second blocking block 212 will be reset by the flexible spring 56, so that the detector 3 can be installed better.

[0038] The movement of the mounting rod 21 can drive the protective device 5 to protect the detector 3. When the mounting rod 21 moves downward, it can push the force rod 52. When the force rod 52 is pushed by the mounting rod 21, it will move into the hydraulic cylinder 51. When the force rod 52 moves into the hydraulic cylinder 51, the hydraulic rod 53 will move out of the hydraulic cylinder 51 due to the squeezing force of the force rod 52. Thus, when the hydraulic rod 53 moves, it can drive the silicone plate 54 to move, thereby protecting the installed detector 3 inside. This allows the moisture in the air entering the detector 3 to be absorbed, ensuring that the detector 3 can work normally in a humid environment and avoiding malfunctions caused by the battery's operating environment.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
