[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a temperature and humidity recorder for an energy storage cabinet. The temperature and humidity recorder includes a PCB 300, a power supply battery 100, and a fixing structure for the built-in battery. The power supply battery 100 is installed on the fixing structure for the built-in battery.

[0040] The temperature and humidity recorder also includes a housing 200, a PCB 300, and a mounting structure for the built-in battery, all housed within the housing 200. The structure of the housing 200 will not be described in detail here.

[0041] like Figure 3 and Figure 4 As shown, the mounting structure for the built-in battery includes a base 1 and a top cover 3. The base 1 has a receiving groove 11, and the first side wall 111 of the receiving groove 11 has an opening 12. A battery holder 2 is provided in the receiving groove 11, which is used to fix the power supply battery 100. The battery holder 2 is spaced apart from the first side wall 111. The top cover 3 includes a top cover body 31 and a baffle plate 32. The baffle plate 32 is connected to the top cover body 31. The top cover body 31 covers the opening of the receiving groove 11. The baffle plate 32 is inserted between the battery holder 2 and the first side wall 111. The baffle plate 32 closes part of the opening 12, allowing the battery holder 2 to be exposed at the opening 12. The PCB 300 is placed on the side of the base 1 away from the opening 12.

[0042] The built-in battery fixing structure provided in this embodiment, when the top cover body 31 is placed over the groove of the receiving groove 11, the shielding plate 32 blocks part of the opening 12, allowing the battery holder 2 to be exposed at the opening 12. The base 1, the top cover body 31 and the shielding plate 32 surround the outside of the battery holder 2. The part of the battery holder 2 exposed at the opening 12 is set away from the PCB 300 inside the temperature and humidity recorder, so that the power supply battery 100 is isolated from the PCB 300. If the power supply battery 100 explodes, the generated high-temperature gas will leak out through the opening 12 that is not blocked by the shielding plate 32, reducing damage to the PCB 300, protecting the collected data and improving the safety of the temperature and humidity recorder.

[0043] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the top cover body 31 includes a cover plate 311 and a baffle plate 312. The cover plate 311 has baffle plates 312 on three of its edges, and a shielding plate 32 is connected to the other edge of the cover plate 311. Both the shielding plate 32 and the baffle plate 312 extend towards the same side of the cover plate 311. The cover plate 311 covers the opening of the receiving groove 11, and the baffle plate 312 is placed on the outside of the side wall of the receiving groove 11 and fits against the side wall of the receiving groove 11. The top cover body 31 seals the opening of the receiving groove 11. In the event of an explosion of the power supply battery 100, the generated high-temperature gas can only escape through the opening 12, which is not blocked by the shielding plate 32, protecting the PCB 300 from damage.

[0044] Optionally, the receiving groove 11 is provided with an inwardly recessed insertion groove 14 on the outer side of the side wall opposite to the first side wall 111, and the insertion groove 14 extends from the top to the bottom. The baffle plate 312 is inserted into the insertion groove 14, and the baffle plate 312 abuts against the side wall and bottom wall of the insertion groove 14 to form a sealing structure, so as to prevent high temperature gas from leaking out between the baffle plate 312 and the outer side wall of the receiving groove 11.

[0045] The outer sides of the two side walls adjacent to the first side wall 111 of the receiving groove 11 may also be recessed with insertion grooves, and the insertion grooves extend from the top to the bottom. The baffle plate 312 is inserted into the corresponding insertion groove. The baffle plate 312 abuts against the side wall and bottom wall of the insertion groove to form a sealing structure, preventing high temperature gas from leaking out between the baffle plate 312 and the outer side wall of the receiving groove 11.

[0046] The cover plate 311, the enclosure plate 312, and the shield plate 32 are integrally formed structures and can be processed by stamping. The top cover 3 is made of sheet metal and has a heat dissipation function.

[0047] In some embodiments, multiple openings 12 are provided, and the multiple openings 12 are spaced apart. Each opening 12 extends from the opening of the receiving groove 11 toward the bottom of the receiving groove 11. This allows the battery holder 2 to be exposed through the opening 12, effectively venting high-temperature gases while ensuring the structural strength of the base 1. Optionally, two, three, or more openings 12 may be provided, without specific limitation.

[0048] In some embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, the bottom of the battery holder 2 is spaced apart from the bottom of the receiving groove 11 to form a liquid storage tank 4. The bottom wall of the battery holder 2 is provided with a liquid outlet 21, which is connected to the liquid storage tank 4. When the power supply battery 100 leaks, the liquid flows into the liquid storage tank 4 through the liquid outlet 21. The liquid storage tank 4 is set below the edge of the opening 12 to prevent the liquid in the liquid storage tank 4 from flowing out through the opening 12 and contaminating and corroding the components inside the temperature and humidity recorder, such as the PCB 300.

[0049] Optionally, since the liquid inside the power supply battery 100 will most likely flow out from the two electrodes of the power supply battery 100, the liquid outlet 21 is provided at both ends of the bottom of the battery holder 2, corresponding to the two electrodes of the power supply battery 100, so as to drain the leaked liquid as soon as possible.

[0050] Multiple liquid outlets 21 are provided at both ends of the bottom of the battery holder 2 to improve the efficiency of liquid flowing out to the storage tank 4.

[0051] The bottom of the receiving groove 11 is provided with a connecting seat 13, which supports the battery holder 2, so that the battery holder 2 is spaced apart from the bottom of the receiving groove 11. The battery holder 2 is connected to the connecting seat 13 through a connector, thereby fixing the battery holder 2 in the receiving groove 11. Optionally, the connecting seat 13 is provided with a threaded hole, and the connector is a bolt, which passes through the battery holder 2 and is screwed into the threaded hole.

[0052] Multiple connectors 13 are preferably provided, and the multiple connectors 13 are spaced apart. The multiple connectors 13 support the battery holder 2, providing a stable support force for the battery holder 2.

[0053] In some embodiments, the two opposite ends of the battery holder 2 and the side of the battery holder 2 away from the opening 12 are respectively spaced apart from the groove wall of the receiving groove 11 to provide heat dissipation space for the power supply battery 100 and improve heat dissipation efficiency.

[0054] In some embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, a heat-conducting element 5 is provided on the side of the top cover body 31 opposite to the receiving groove 11. The heat-conducting element 5 is pressed between the top cover body 31 and the outer shell 200 of the temperature recorder. That is, the heat-conducting element 5 is interference-fitted with both the top cover body 31 and the outer shell 200 of the temperature and humidity recorder, achieving passive heat dissipation, improving heat dissipation efficiency, and evenly distributing the heat from the power supply battery 100 to the outer shell 200. A fin structure can also be provided on the outer side of the outer shell 200 to achieve efficient heat dissipation. The outer shell 200 of the temperature and humidity recorder can be made of aluminum, which has good heat dissipation performance.

[0055] Optionally, the heat-conducting component 5 is a grid-shaped heat-conducting pad, which has a simple structure and good heat dissipation effect. The heat-conducting pad is made of silicone, which has high heat dissipation efficiency and can press against the top cover body 31 and the housing 200 of the temperature and humidity recorder.

[0056] The structure of the battery holder 2 described above is existing technology and will not be described in detail here. The wire 400 connected to the power supply battery 100 passes through the side wall of the battery holder 2 and connects to the PCB 300.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
