Embodiment 1

[0023] Such as figure 1 , figure 2 As shown, the positive electrode bolt 6a of the energy storage device is designed to have a circular axial through hole 1 and a radial hole 2 connecting the inside and outside of the energy storage device.

[0024] See figure 1 , the foil explosion-proof valve 5 is placed in the bottom of the circular axial through hole 1, the material of the positive bolt 6a is aluminum alloy of grade 3003; the shape of the explosion-proof valve 5 is designed to match the shape of the bottom of the axial through hole 1 Circular structure; explosion-proof valve 5 uses copper foil explosion-proof film. The explosion-proof valve 5 is placed inside the hole of the positive bolt 6a, so it is not easy to be damaged during production and use. The radial hole 2 is designed so that the internal pressure of the energy storage device can still be released when the axial through hole 1 is accidentally blocked.

Embodiment 2

[0026] Such as Figure 7 , Figure 4 As shown, the positive bolt 6a of the energy storage device is designed to have a circular axial through hole 1 connecting the inside and outside of the energy storage device, a radial hole 2 and a square groove 3 structure.

[0027] See Figure 7 , the explosion-proof valve 5 is placed in the bottom of the axial through hole 1, and the material of the positive bolt 6a is 6082 aluminum alloy; the shape of the explosion-proof valve 5 is designed to be a circular structure that matches the shape of the bottom of the axial through hole 1; Explosion-proof valve 5 selects aluminum foil explosion-proof film for use. The axial through hole 1 communicates with the outside through the radial hole 2 and the square groove 3. Compared with the embodiment 1, this design further protects the explosion-proof valve and prevents foreign objects from entering through the axial through hole 1 to block or damage the explosion-proof valve. Valve; if the radi...

Embodiment 3

[0029] Such as image 3 , Figure 4As shown, the negative electrode bolt 6b of the energy storage device is designed to have a circular axial through hole 1 connecting the inside and outside of the energy storage device, a radial hole 2 and a square groove 3 structure.

[0030] See image 3 , Figure 5 , put the rubber valve 7 into the bottom of the circular axial through hole 1, the material of the negative electrode bolt 6b is Pb59-1 lead brass alloy; the shape of the rubber valve 7 is designed to match the shape of the bottom of the circular hole 1 Structure; the material of the rubber valve 7 is natural rubber. Such as Figure 5 As shown, when the internal pressure of the energy storage device is higher than the maximum pressure that the rubber valve can withstand, the top 4 of the rubber valve will be burst to achieve the purpose of releasing the internal pressure of the energy storage device. According to the required explosion-proof pressure, the thickness of the t...

Abstract

The invention provides an explosion-proof structure of an energy-storing device, and the structure is characterized in that at least one hole communicated with the interior of the energy-storing device is arranged in a positive pole bolt of the energy-storing device, at least one hole communicated with the exterior of the energy-storing device is arranged in a negative pole bolt, and rubber explosion-proof valves or foil explosion-proof valves are arranged in the holes. The explosion-proof structure has the characteristics of saving space, being difficult to be damaged during the production or the use, and having consistent explosion-proof pressure and good sealing effect; the adoption of the design of the multiple holes can well protect the explosion-proof valves, and a ventilation channel of the explosion-proof structure can be increased for leading the energy-storing device to realize better pressure relief; the rubber valves can be selected, thereby having good sealing and explosion-proof effects, being difficult to be damaged due to external force, having very high consistency, being applied in most of the energy-storing devices, being unnecessary to carry out brazing, laser welding and other production process steps, and having the advantages of simpler production and lower cost; and the explosion-proof valves can also select aluminum foils, copper foils, aluminum alloy foils, copper alloy foils and the like, thereby well protecting the explosion-proof valves, and being applied in the positive pole bolts or the negative pole bolts.
