Description

Technical Field

[0001] The present invention relates to the technical field related to gas generators, and in particular to a second-stage connecting device of a double-stage generator. Background Art

[0002] A gas generator is a device that receives an electrical signal and rapidly generates a large amount of gas in a very short time, thereby enabling the upstream product to perform work. Commonly used in automotive airbags, gas generators have seen rapid growth in various industries, including fire protection and public welfare, in the past two years. Airbags are standard equipment in current vehicles and primarily consist of airbags and gas generators. When activated, the gas generator receives an electrical signal and rapidly generates gas to fill the airbag, creating a protective cushion between the occupant and the vehicle's interior components. A gas generator typically includes an igniter, a pyrotechnic agent, a gas-generating agent, and several structural components. When activated, the igniter receives an electrical signal to initiate a detonation, igniting the pyrotechnic agent, which in turn ignites the gas-generating agent, producing a large amount of gas.

[0003] Existing ignition devices are designed with interfaces on their structures, and automobile circuit switch assemblies are designed with connectors corresponding to the interfaces. The automobile circuit switch assembly and the ignition device are electrically connected through the cooperation of the connectors and the interfaces. However, the current problem is that this plug-in connection method of the connectors and the interfaces has low stability and a weak connection. In the event of a car collision, the connectors are prone to premature detachment due to severe collisions. If the connectors detach from the interfaces, the gas generator will not be able to work properly, which poses a huge hidden danger to the driver's safety. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art in which the plug-in connection between the connector of the automobile circuit switch assembly and the interface of the ignition device has low stability and a loose connection, and provides a second-stage connection device for a two-stage generator that can improve the connection stability and connection firmness.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A second-stage connection device for a two-stage generator includes a base plate, on which an ignition device and a fixing seat are fixed, an interface is provided on the ignition device, a joint is provided at the interface, the interface and the joint are detachably connected, a concave pressure block matching the joint is provided on the fixing seat, the concave pressure block and the fixing seat are slidably connected up and down, the joint is placed between the two side plates of the concave pressure block, the two side plates of the concave pressure block and the bottom plate of the concave pressure block are provided with positioning top blocks, the positioning top blocks are distributed in a ring shape on the outside of the joint with the joint as the center, and the positioning top block and the concave pressure block are movably connected.

[0007] After the joint is installed at the interface, the concave pressure block is controlled to move from top to bottom to press the joint, so that the joint is fixed in the vertical direction. Then, the outer positioning top block is controlled to move toward the joint from all sides at the same time to jointly support the joint and fix the joint in the horizontal direction, thereby achieving the purpose of improving the connection stability and connection firmness of the joint at the interface.

[0008] Preferably, the connector is cylindrical in shape, with an annular flange fixed to the outer side wall of the connector. The annular flange is located below the concave pressing block. The minimum distance between the two side plates of the concave pressing block is greater than the cross-sectional diameter of the connector, and the minimum distance between the two side plates of the concave pressing block is less than the outer diameter of the annular flange. The connector has a simple structure, is easy to process and injection mold, and has low production costs. When the concave pressing block moves from top to bottom, the annular flange on the connector is pressed by the two side plates on it, thereby achieving vertical fixation of the connector, and placing the connector on the inner side of the concave pressing block so that the positioning top block can fix the connector horizontally. The operation is simple and the fixation is convenient.

[0009] Preferably, the material of the connector is PEEK, which has the advantages of high temperature resistance, wear resistance, corrosion resistance, high strength, and easy processing, and has excellent flame retardancy and electrical properties, and is safe and reliable.

When the concave pressure block is pressed on the annular flange of the joint, the locking pin on the locking block is re-inserted into the locking pin positioning hole to fix the movable column and the concave pressure block. The structure is simple, the operation is convenient, it is easy to disassemble and assemble, and the connection is stable.

The up and down movement of the movable column in the movable column slide groove is a coarse adjustment of the position of the concave pressure block. When the movable column is fixed, the staff can fine-tune the concave pressure block by rotating the adjusting screw, so that the concave pressure block tightly presses the annular flange on the joint, and finally tightens the fastening nut and the pair of adjusting screws to complete the fixation. The structure is simple, the operation is convenient, and it is easy to disassemble and assemble, and it greatly improves the fixing effect of the joint in the vertical direction.

The positioning top block on the sliding pressure rod and the positioning top blocks on the two swing pressure rods are annular, and the angles between them are evenly distributed around the joint. When fixing, the staff controls the sliding pressure rod to slide toward the joint, so that the positioning top block on it supports the joint from the side. At the same time, through the transmission action of the transmission connecting rod, the swing pressure rod will be driven to swing synchronously, so that the positioning top block on it also supports the joint from the side, thereby achieving the purpose of the outer positioning top blocks moving toward the joint from all sides at the same time and supporting the joint together.
