Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a rapid inflation tool for an explosion-proof valve. Background Technology

[0002] With the rapid development and growth of my country's new energy industry, the safety performance requirements for power battery packs used in electric vehicles are becoming increasingly stringent. The safety of various electronic components and core components such as battery cells within the battery pack system is paramount. To ensure safe and reliable operation, it needs to be waterproof and dustproof, theoretically requiring a completely sealed state. Simultaneously, to meet the needs of internal gas emission and balancing the internal and external pressure differences during battery pack use, a certain number of explosion-proof valves or balancing valves are installed at different locations within the battery pack housing. After installing these valves, the battery pack housing needs to undergo sealing performance testing to ensure its airtightness.

[0003] When performing a sealing test, the battery pack needs to be inflated. However, traditional inflation tools have some problems when used. For example, without a magnet, the gas cannot be inflated quickly, causing the battery pack to bulge and resulting in customer complaints. Utility Model Content

[0004] The purpose of this invention is to provide a rapid inflation fixture for explosion-proof valves, addressing the shortcomings of existing technologies.

[0005] This utility model is achieved using the following technical solution:

One end of the inflation tube is connected to an air source through an air pipe, and the other end of the inflation tube is provided with a cylindrical tube, which is located inside the base. The base is provided with a retaining plate, which engages with the battery pack explosion-proof valve retaining groove.

[0007] Furthermore, the inflation tube also includes a quick-connect fitting, a knob, and a limiting block. The lower end of the inflation tube is provided with the cylindrical tube, and the outer circumference of the upper end of the inflation tube is provided with threads. The lower end of the knob is threadedly connected to the inflation tube, and the quick-connect fitting is provided at the center of the upper end of the knob. The quick-connect fitting is threadedly connected to the knob. The limiting block is located between the cylindrical tube and the knob, and the quick-connect fitting is connected to the air source through an air tube.

The powerful magnet is fixed to the center position of the lower end face of the cylindrical tube by a vent bolt, and the sealing ring is embedded in the outer periphery of the lower end face of the cylindrical tube.

[0009] Furthermore, the inflation tube is also fitted with a spring, and the lower end of the spring is limited by the cylindrical tube, while the upper end of the spring is limited by the inner upper surface of the base.

[0010] Furthermore, the upper end of the base is provided with a protrusion, the limiting block is located between the protrusions, the C-shaped opening of the base is provided with a locking block, the locking block is connected to the base by a flat-head bolt, the locking block is provided with a buckle, and the buckle is located at the lower end of the limiting block.

[0011] Furthermore, the lower end of the base is provided with the retaining plate, which is connected to the base by countersunk bolts. The retaining plate has a C-shaped opening structure, and the C-shaped opening of the retaining plate is correspondingly set with the C-shaped opening of the base.

[0012] Furthermore, a gasket is provided between the card plate and the base, and the threaded end of the countersunk bolt passes through the card plate and the gasket and is threadedly connected to the base.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

The inflation tube has a limiting block that engages with a protrusion on the upper end of the base to limit axial rotation of the inflation tube. A cylindrical tube is located at the lower end of the inflation tube, which engages with the explosion-proof valve on the battery pack. A sealing ring is installed on the lower end face of the cylindrical tube to ensure a seal between the fixture and the explosion-proof valve during inflation. A powerful magnet is fastened to the center of the lower end face of the cylindrical tube via the vent screw, securing the explosion-proof valve core rod during inflation. The spring is firmly attached to the inflation tube, with its lower end limited by a cylindrical tube and its upper end limited by the inner upper surface of the base. It acts as a clamping force during inflation. The locking block is fixed to the base with bolts. When the inflation tube is pressed down, the locking block abuts against the lower end of the limiting block to limit the downward pressure. The locking plate is fixed to the lower end of the base with countersunk screws. A washer is located between the locking plate and the base. The thickness of the washer forms a groove between the locking plate and the base, which cooperates with the groove of the explosion-proof valve of the battery pack to fix the tooling.

[0015] When needed, simply connect the inflation tube to the quick connector, then insert the clip into the corresponding battery pack explosion-proof valve slot, and then rotate the inflation tube 90 degrees by holding the knob. Under the action of the spring, the lower end of the inflation tube is sealed to the explosion-proof valve through the sealing ring. At this time, the strong magnet firmly holds the explosion-proof valve core rod, ensuring that the battery pack will not bulge during rapid inflation. It features high inflation efficiency, simple use, and high safety. Attached Figure Description
