[0047] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0048] Example 1

[0049] This embodiment discloses a protective storage device, which includes an inner water box pressure relief valve device. Figure 1 , Figure 2 and Figure 3 As shown, the inner tank water box pressure relief valve device includes a pressure relief valve accommodating component 1, a fusible metal component 2 and an inner tank shell 4. The pressure relief valve accommodating component 1 is connected to the outer surface of the inner tank shell 4. The inner tank shell 4 has a chip storage cavity and a water injection cavity that are not connected to each other. The chip storage cavity is used to store chips, and the water injection cavity has water. The water injection cavity covers the chip storage cavity, so that the water can be used to keep the temperature around the chip at a safe temperature to prevent the chip from being damaged by heat.

[0050] The pressure relief valve accommodating component 1 is made of elastic material, and has an accommodating chamber 11 inside. Pressure relief holes 12 are provided on the inner and outer walls of the pressure relief valve accommodating component 1. The fusible metal component 2 is arranged in the accommodating chamber 11, and the fusible metal component 2 is sealed in the two pressure relief holes 12. The accommodating chamber 11 is first connected with the two pressure relief holes 12 and the water injection chamber, and then the fusible metal component 2 is arranged in the accommodating chamber 11 and sealed in the two pressure relief holes 12. When a fire occurs in the vehicle, after the water temperature in the inner shell 4 rises to the melting temperature of the fusible metal component 2, the fusible metal component 2 will melt, and the hot steam pressure in the inner shell 4 will exert an outward force on the fusible metal component 2, so that the hot steam in the water injection chamber will be discharged outward through the two pressure relief holes 12 and the accommodating chamber 11, thereby achieving the effect of pressure relief and temperature reduction, and ensuring the safety of the chip in the inner shell 4.

[0051] In the present embodiment, the pressure relief valve accommodating component 1 is made of elastic material, and the assembly can be completed by simply inserting the fusible metal component 2 into the accommodating cavity 11, which has a small size, low cost, and simple installation process; at the same time, the pressure relief valve accommodating component 1 made of elastic material will automatically install the fusible metal component 2 in place in the accommodating cavity 11 under the action of the deformation elastic force, and the assembly requirements are low; the fusible metal component 2 is set in the accommodating cavity 11 and sealed on the two pressure relief holes 12 on the inner wall and the outer wall of the pressure relief valve accommodating component 1, so as to facilitate the realization of the sealing effect, and the fusible metal component 2 will play a certain blocking role on the pressure relief hole 12, thereby ensuring high stability during the pressure relief and cooling process.

[0052] In this embodiment, the material of the liner shell 4 is an elastic material, the pressure relief valve accommodating component 1 is connected to the outer surface of the liner shell 4, and the liner shell 4 and the pressure relief valve accommodating component 1 are integrally formed. The materials of the liner shell 4 and the pressure relief valve accommodating component 1 are both elastic materials, and the liner shell 4 and the pressure relief valve accommodating component 1 are formed at one time by hot pressing, blow molding, vulcanization and other processes using elastic materials, further realizing that the processing and manufacturing of the liner water box pressure relief valve device is very convenient, and the overall structural stability is high, and the safety stability is higher.

[0053] The material of the pressure relief valve housing component 1 can be silicone rubber, or an elastic high temperature resistant polymer material. The material of the liner shell 4 can be silicone rubber, or an elastic high temperature resistant polymer material.

[0054] The inner diameter of the pressure relief hole 12 is 0.5-5 mm. This makes the opening small, easy to seal, and highly stable during the pressure relief and temperature reduction process. The fusible metal component 2 is combined with the pressure relief valve receiving component 1, and the fusible metal component 2 covers the pressure relief hole 12 and fills the inside of the pressure relief hole 12, which has higher reliability and firmness.

[0055] like Figure 1 As shown, in this embodiment, the number of the pressure relief valve accommodating component 1 and the fusible metal component 2 are both two, and the two pressure relief valve accommodating components 1 are arranged at the diagonal positions of the upper and lower surfaces of the inner shell 4. The pressure relief holes 12 with a diameter of 0.5 to 5 mm are opened at the diagonal positions of the upper and lower surfaces of the inner shell 4 to relieve pressure and cool down. No matter how the inner shell water box pressure relief valve device is placed, there will be at least one pressure relief hole 12 completely in the liquid in the inner shell 4, and at least one pressure relief hole 12 is close to or in the waterless cavity at the top of the inner shell 4. When heat is introduced into the inner shell 4, the upper cavity part will be heated and heated faster, and the liquid surface adjacent to the cavity will also heat up earlier. The upper inner shell 4 is more likely to heat up to the melting point of the fusible metal component 2, so that the fusible metal component 2 melts and is broken by the high-pressure steam in the inner shell 4 to release pressure. The lower pressure relief hole 12 in the liquid is completely immersed in the liquid. Only when the bottom liquid is heated to the melting point of the fusible metal component 2, the lower pressure relief hole 12 will break and release pressure. In addition, the pressure relief hole 12 located in the liquid, the fusible metal component 2 can quickly transfer heat to the liquid in the inner shell 4, thereby further ensuring that the lower pressure relief hole 12 will reach the melting point of the fusible metal component 2 later than the upper pressure relief hole 12. When the pressure is released, the water in the inner shell 4 will not be sprayed out first, which is beneficial to improve the fireproof performance of the inner shell 4. While reducing the production cost, it can also ensure that the liquid in the inner shell 4 will not be sprayed out first.

[0056] In this embodiment, the fusible metal component 2 includes a fusible metal body 21 and a high temperature resistant metal blocking ring 22. The high temperature resistant metal blocking ring 22 has a through hole 221, and the two ends of the through hole 221 correspond to the two pressure relief holes 12. The fusible metal body 21 is embedded in the through hole 221. The middle area of ​​the high temperature resistant metal blocking ring 22 is provided with a through hole 221. The fusible metal body 21 is first poured into the through hole 221, so that the fusible metal body 21 will be located in the high temperature resistant metal blocking ring 22 and form a fusible metal component 2 as a whole. Then, the fusible metal component 2 is plugged into the accommodating cavity 11, so that the two ends of the through hole 221 correspond to the two pressure relief holes 12. By embedding the fusible metal body 21 in the high temperature resistant metal blocking ring 22, the position of the pressure relief point can be further guaranteed. Among them, the high temperature resistant metal blocking ring 22 can be made of stainless steel, copper, etc., so that the fusible metal component 2 is a combination of fusible metal and other high temperature resistant metal materials.

[0057] The outer diameter of the fusible metal component 2 is larger than the inner diameter of the accommodating cavity 11, so that the outer surface of the fusible metal component 2 is tightly against the inner wall surface of the accommodating cavity 11. The pressure relief valve accommodating component 1 is formed of elastic material, and the fusible metal component 2 is designed to be slightly larger than the inner size of the accommodating cavity 11. After the fusible metal component 2 is placed in the accommodating cavity 11, the elastic accommodating cavity 11 can tightly wrap the fusible metal component 2 to enhance the sealing performance of the inner tank water box pressure relief valve device.

[0058] The fusible metal component 2 is bonded to the pressure relief valve receiving component 1. The outer surface of the fusible metal component 2 can be coated with glue before being placed in the receiving cavity 11, so that the sealing between the inner wall surface of the pressure relief valve receiving component 1 and the fusible metal component 2 is further enhanced.

[0059] like Figure 2 and Figure 3 As shown, the inner water box pressure relief valve device also includes a guide component 3, which is connected to the outer surface of the pressure relief valve accommodating component 1 and protrudes outward, and has at least one guide groove 31, which is connected to the pressure relief hole 12. The pressure relief valve accommodating component 1 is an internally hollow structure, and a pressure relief hole 12 with a diameter of 0.5 to 5 mm is provided on the inner and outer walls. When the water in the inner liner outer shell 4 is heated and evaporated and the fusible metal component 2 is melted and conducted, the steam can be discharged through the pressure relief hole 12 to keep the internal temperature of the inner liner outer shell 4 not exceeding 100°C. At the same time, under the action of the internal pressure of the inner liner outer shell 4, the outer surfaces of the inner liner outer shell 4 and the pressure relief valve accommodating component 1 will be elastically expanded and pressed against the external structural surface, and the outer wall around the pressure relief hole 12 may be pressed outward and pressed against the external structural surface to cause the pressure relief hole 12 to be closed. The guide component 3 is arranged on the outer wall of the pressure relief valve accommodating component 1, which protrudes outward and has a guide groove 31, so that the steam will be discharged smoothly through the guide groove 31, which greatly improves the safety and stability of the inner liner water box pressure relief valve device.

[0060] There are multiple guide grooves 31, all of which are connected to the pressure relief hole 12, and the multiple guide grooves 31 extend outward in different directions to achieve smooth outward discharge of steam. In this embodiment, there are four guide grooves 31.

[0061] like Figure 1 and Figure 2 As shown, the liner shell 4 includes an liner shell body 41 and a seal 42, the pressure relief valve accommodating component 1 is connected to the outer surface of the liner shell body 41 and is integrally processed and formed, the seal 42 is sealed and connected to one side of the liner shell body 41, and a water injection cavity is formed between the seal 42 and the liner shell body 41. When the liner shell body 41 is processed and manufactured, an opening is provided on one side of the liner shell body 41, and the seal 42 is connected to one side of the liner shell body 41 and sealed and covered on the opening, thereby forming a completely sealed water injection cavity, realizing that the liner shell 4 is easy to process and manufacture, and realizing a small volume, low cost, and simple installation process. Among them, the seal 42 can be connected to the liner shell body 41 by hot pressing or gluing.

[0062] Example 2

[0063] like Figure 4 and Figure 5 As shown, the structure of the inner tank water box pressure relief valve device of this embodiment is the same as that of embodiment 1, and only the differences are described. In this embodiment 2, the fusible metal component 2 includes at least one protrusion 23 protruding outward, and the protrusion 23 can extend into the pressure relief hole 12. The contact area between the fusible metal component 2 and the pressure relief valve accommodating component 1 is large, and the sealing effect of the fusible metal component 2 on the pressure relief hole 12 is effectively enhanced.

[0064] The protrusion 23 may also penetrate the pressure relief hole 12 and extend into the inner shell 4 . The protrusion 23 extends into the inner shell 4 , so that the fusible metal component 2 is in full contact with the liquid in the inner shell 4 .

[0065] In the present embodiment 2, specifically, the high temperature resistant metal blocking ring 22 has a protrusion 23 protruding outward, the protrusion 23 penetrates the pressure relief hole 12 and extends into the inner shell 4, and at least one pressure relief groove 231 is opened at the bottom of the protrusion 23, and the pressure relief groove 231 is connected with the perforation 221. By pre-opening the pressure relief groove 231 in the protrusion 23 below the high temperature resistant metal blocking ring 22, the fusible metal body 21 is also poured into the pressure relief groove 231 during the pouring, so that the fusible metal body 21 can be more fully in contact with the liquid in the inner shell 4, so that the temperature is more fully conducted. Further, when the water in the inner shell 4 is heated and boiled and evaporated, resulting in the pressure relief of the inner shell water box pressure relief valve device, when the water-absorbing resin particles block the pressure relief hole 12, the steam can be released through the pressure relief groove 231 to prevent the temperature and pressure in the inner shell 4 from being too high, which greatly improves the safety and stability of the inner shell water box pressure relief valve device.

[0066] like Figure 4 As shown, the accommodating cavity 11 has at least one buckle portion 13, and the outer surface of the fusible metal component 2 has at least one matching portion 24. The buckle portion 13 is a convex structure protruding outward or a groove recessed inward. The buckle portion 13 corresponds to the matching portion 24 one by one, and the buckle portion 13 is buckled and connected to the matching portion 24. By designing a convex structure protruding outward or a groove recessed inward on the contact surface between the pressure relief valve accommodating component 1 and the fusible metal component 2, the structural connection strength is effectively enhanced. And the sealing is further enhanced and the installation and positioning of the fusible metal component 2 are facilitated to simplify the assembly process. Among them, the buckle portion 13 and the matching portion 24 can be concave-convex structure rings, and the number and setting position of the buckle portion 13 and the matching portion 24 can be unlimited.

[0067] Example 3

[0068] like Figure 6 As shown, the structure of the inner tank water box pressure relief valve device of this embodiment is the same as that of embodiment 1, and only the differences are described. In embodiment 1, the overall shape of the fusible metal component 2 can be block-shaped or sheet-shaped. In this embodiment 3, the fusible metal component 2 is spherical and is located in the accommodating cavity 11, so that the fusible metal component 2 and the pressure relief valve accommodating component 1 cooperate with each other to form a spherical valve structure.

[0069] In the present embodiment 3, the fusible metal component 2 is an integrally formed fusible metal material, and the fusible metal component 2 is a spherical component, and the spherical component is entirely composed of fusible metal material, that is, the fusible metal component 2 is a whole piece of fusible metal material, and has a simple structure and is convenient to manufacture. Among them, the volume of the accommodating cavity 11 is slightly smaller than the overall volume of the fusible metal component 2. When the fusible metal component 2 is inserted into the pressure relief valve accommodating component 1, since the pressure relief valve accommodating component 1 is made of elastic material, the inner wall surface of the pressure relief valve accommodating component 1 and the fusible metal component 2 can be tightly pressed, thereby further enhancing the sealing performance of the inner tank water box pressure relief valve device.

[0070] In this embodiment 3, the outer surface of the fusible metal component 2 has a protective layer. A protective layer can be plated on the surface of the fusible metal component 2, or the protective layer can be covered on the surface of the fusible metal component 2, that is, the anti-oxidation primer material covers the surface of the fusible metal component 2; the protective layer makes the fusible metal component 2 less susceptible to oxidation. The material of the protective layer can be gold, silver, copper, etc.

[0071] Furthermore, adhesive may be applied when installing the fusible metal component 2 to make the pressure relief valve receiving component 1 and the fusible metal component 2 more tightly bonded, thereby further enhancing the sealing performance.

[0072] Example 4

[0073] like Figure 7 As shown, the structure of the inner tank water box pressure relief valve device of this embodiment is the same as that of the embodiment 3, and only the differences are described. In this embodiment 4, the fusible metal component 2 includes at least one protrusion 23 protruding outward, and the protrusion 23 can extend into the pressure relief hole 12, effectively enhancing the sealing effect of the fusible metal component 2 on the pressure relief hole 12. Of course, the protrusion 23 can also pass through the pressure relief hole 12 and extend into the inner tank shell 4, so that the fusible metal component 2 is fully in contact with the liquid in the inner tank shell 4.

[0074] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
