Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

An explosion-proof valve mounting structure, a battery pack, and a vehicle according to an embodiment of the present utility model are described below with reference to fig. 1 to 7.

As shown in fig. 1 to 6, the explosion-proof valve mounting structure according to the embodiment of the present utility model includes: a panel 1 and an explosion-proof valve 2 are installed. The installation panel 1 comprises a panel body 11, an installation part 12 and a protection part 13, wherein the installation part 12 and the protection part 13 are arranged on the panel body 11, the protection part 13 is arranged on the periphery of the installation part 12 and protrudes relative to the installation part 12 so as to define a protection cavity 15 with the installation part 12, and at least part of the explosion-proof valve 2 is arranged in the protection cavity 15.

According to the explosion-proof valve mounting structure of the embodiment of the utility model, the protection part 13 is arranged on the periphery of the mounting part 12 and defines the protection cavity 15 with the mounting part 12, so that the explosion-proof valve 2 can be mounted in the protection cavity 15, the circumference of the explosion-proof valve 2 is protected by the protection part 13, the probability of failure of the explosion-proof valve 2 due to collision is reduced, and at least part of the explosion-proof valve 2 is arranged in the protection cavity 15 due to the fact that the protection cavity 15 is formed on the mounting panel 1, compared with the scheme of mounting the cover cap 4 outside the explosion-proof valve 2 in the related art, the occupation space of the explosion-proof valve mounting structure is reduced, and the cost is lower.

It will be appreciated that the protecting portion 13 and the mounting portion 12 are both protruded toward the outside of the panel body 11, and the height of the protecting portion 13 is higher than that of the mounting portion 12, whereby the protecting portion 13 and the mounting portion 12 can enclose the protecting chamber 15 to protect the explosion-proof valve 2.

As shown in fig. 7, in the related art, the cover cap 4 is installed outside the explosion-proof valve 2, and since the cover cap 4 and the explosion-proof valve 2 are fixed by adopting a bolt connection manner, when the battery pack vibrates, there is a risk that the cover cap falls off and fails due to the attenuation of the bolt torque caused by the vibration. The protection part 13 and the panel body 11 of the explosion-proof valve mounting structure can be integrally formed, so that the mounting step of a valve cover can be omitted, and the mounting and manufacturing cost of the explosion-proof valve mounting structure is reduced.

When the internal pressure of the battery box body is increased due to thermal runaway of the battery core, the air pressure in the battery box body can push the explosion-proof valve 2 to discharge air, fragments or impact inside the battery core can cause fragments formed by components inside the battery box body to be guided and sprayed out through the protection cavity 15 formed by the protection part 13 and the mounting part 12, so that the problems of unordered splashing of fragments, fragments and sprayed electrolyte are avoided, and the safety performance of the explosion-proof valve mounting structure is improved.

Alternatively, as shown in fig. 6, one side of the explosion-proof valve 2 abuts against the mounting portion 12, and the other side of the explosion-proof valve 2 (the side of the explosion-proof valve 2 away from the mounting portion 12) is not higher than the opening of the protection chamber 15. It will be appreciated that the inner side of the valve 2 is in contact with the mounting portion 12 and the outer side of the valve 2 does not exceed the opening of the protection cavity 15. In other words, the end surface of the end of the protection portion 13 away from the panel body 11 is higher than the outer side surface of the explosion-proof valve 2, so that the explosion-proof valve 2 is disposed in the protection cavity 15 and does not protrude into the protection cavity 15. According to the explosion-proof valve mounting structure, the explosion-proof valve 2 is arranged in the protection cavity 15, so that one side, far away from the mounting part 12, of the explosion-proof valve 2 can be protected, parts around the explosion-proof valve 2 are prevented from being extruded towards the direction of the explosion-proof valve 2 to collide with the explosion-proof valve 2, and the safety of the explosion-proof valve 2 in use is further improved.

In one example, as shown in fig. 6, the difference in height between the other side of the explosion-proof valve 2 (the side of the explosion-proof valve 2 away from the mounting portion 12) and the opening of the protection chamber 15 is 3mm or more and 5mm or less. In other words, the difference in height between the side of the explosion-proof valve 2 away from the mounting portion 12 and the end face of the protecting portion 13 away from the end of the panel body 11 is 3mm or more and 5mm or less. For example, the height difference may be 3mm, 4 mm or 5 mm. Through a great deal of experimental study, the inventor of the application finds that when the height difference adopts the parameter design, the protection effect of the explosion-proof valve 2 can be ensured, and the length dimension of the protection part 13 can be shortened, so that the occupied space of the installation structure of the explosion-proof valve is reduced, and the space utilization rate is improved.

It will be appreciated that, since the height of the frame portion 111 is higher than the height of the mounting portion 12, and the mounting portion 12 is in contact with the explosion-proof valve 2, at least part of the explosion-proof valve 2 may also be located in the accommodation space enclosed by the frame portion 111. In other words, the installation interface of the explosion-proof valve 2 and the installation part 12 adopts a sinking type design, so that the problem of outwards convex installation of the explosion-proof valve 2 can be solved, the occupied space of the installation structure of the explosion-proof valve is reduced, and the space utilization rate is improved.
