Description

Technical Field

[0001] The utility model relates to the technical field of sealing, in particular to a sealing fixture for an explosion-proof valve of a power battery of a new energy vehicle. Background Technique

[0002] The power battery of a new energy vehicle is a power source that provides power for an electric vehicle. The power battery of a new energy vehicle is generally composed of battery pack modules. The battery pack modules are generally provided with explosion-proof valves. The function of the explosion-proof valve is to automatically crack and release gas before the gas inside the battery pack module reaches the explosion limit, thereby avoiding the explosion of the battery pack; in addition, during the overhaul process of the battery pack module, in some cases, it is necessary to temporarily seal the explosion-proof valve on the battery pack module. Most of the temporary sealing methods are to apply sealant to the surface of the explosion-proof valve for temporary local sealing, and then remove the sealant after the overhaul is completed.

[0003] However, there are still some defects in the temporary sealing methods adopted during the overhaul process of the existing battery pack modules, and some practical functions still need to be improved. For example, the method of using sealant to temporarily seal the explosion-proof valve is too cumbersome, and the time cost spent by the staff on applying or removing the glue is relatively high. Moreover, due to the high viscosity of the sealant, the staff often needs to use a large amount of force to remove the glue, and it is easy to damage the explosion-proof valve due to excessive force, which makes the explosion-proof valve scrapped and unable to be used normally, thus causing unnecessary losses. Therefore, there is an urgent need for a sealing fixture for an explosion-proof valve of a power battery of a new energy vehicle to solve the above problems. Summary of the Utility Model

The upper end of the rotating clamping member 6 is movably clamped inside the first through hole 3011.

[0028] Specifically, the top seal 401 and the sealing collar 5 can be set to a variety of different sizes to adapt to explosion-proof valves 2 of various different size specifications. The sealing collar 5 is made of rubber material.

[0029] The clamping assembly 3 of the present utility model further includes a first clamping block 302 and a second clamping block 303. The first clamping block 302 and the second clamping block 303 are respectively arranged on both sides of the main support member 301 of the clamping assembly 3. The first clamping block 302 and the second clamping block 303 are respectively provided with a first groove 3021 and a second groove 3031. On both sides of the explosion-proof valve 2, there are respectively arranged a first clamping block 201 and a second clamping block 202.

[0030] Specifically, the first groove 3021 and the second groove 3031 can be set to different sizes according to actual situations, so as to adapt to explosion-proof valves 2 of various different size specifications.

[0031] At the bottom of the top seal 401 of the present utility model, there is provided a second through hole 4011. The upper end of the support main rod 402 is inserted into the second through hole 4011 and fixedly connected with the top seal 401.

[0032] At the lower end of the support main rod 402 of the present utility model, there is fixedly provided a fixed grip 7. The fixed grip 7 is provided with a third through hole 701.

[0033] One end of the explosion-proof valve 2 of the present utility model is provided with a breathable film 203. The interior of the power battery 1 is communicated with the outside through the breathable film 203 on the explosion-proof valve 2.

[0034] Combined with the attached Figures 1-9 , the using process of a sealing fixture for an explosion-proof valve of a power battery for a new energy vehicle of the present utility model is as follows:

[0035] First, the staff holds both sides of the main support member 301 with one hand, and then holds the fixed grip 7 with the other hand and applies a downward pulling force to it. The support main rod 402 fixedly connected with the fixed grip 7 will then move downward, simultaneously driving the top seal 401 and the rotating clamping member 6 to move downward. At this time, the middle spring 403 is in a compressed state, and the upper end of the rotating clamping member 6 disengages from the first through hole 3011 at the bottom of the main support member 301, and then the rotating clamping member 6 is rotated and twisted to be clamped to the bottom of the main support member 301;

[0036] Next, the first grooves 3021 and 3031 on the first clamping block 302 and the second clamping block 303 are snapped onto the first clamping block 201 and the second clamping block 202 on the explosion-proof valve 2. At this time, the upper end of the top seal 401 contacts and abuts against one end of the explosion-proof valve 2, and the sealing ring 5 on the top seal 401 forms a partial seal with one end of the explosion-proof valve 2, thereby isolating the breathable film 203 on the explosion-proof valve 2 from the outside, and realizing the partial seal of the explosion-proof valve 2.

[0037] Subsequently, when the partial seal of the explosion-proof valve 2 is completed, the first grooves 3021 and 3031 on the first clamping block 302 and the second clamping block 303 are disengaged from the first clamping block 201 and the second clamping block 202 on the explosion-proof valve 2. Then, the rotary clamping member 6 is rotated and twisted again, so that the rotary clamping member 6 moves upward and its upper end is reinserted into the first through hole 3011 of the main support member 301. At this time, the support main rod 402 and the top seal 401 move upward simultaneously, and the middle spring 403 is in an uncompressed state. Finally, the sealing fixture is placed and stored as a whole.

[0038] The above has described the present utility model in detail. The above is only the preferred embodiment of the present utility model, and it cannot limit the scope of implementation of the present utility model. That is, all equal changes and modifications made according to the scope of this application should still fall within the scope covered by the present utility model.
