Description

Technical Field

[0001] This utility model relates to the field of airbag generator technology, specifically to an airbag generator mounting assembly. Background Technology

[0002] An airbag is a device that inflates to protect occupants during a collision before a secondary impact occurs. As an auxiliary device to the seatbelt restraint system, the airbag is called an airbag system. An airbag system consists of an integrated airbag module (airbag and inflation mechanism, gas generator), a collision sensor system that senses a collision and sends deployment commands to the airbag module, and wiring harnesses that transmit the signals from the sensors.

[0003] Currently, replacing a damaged airbag generator requires installation and disassembly. This is typically done manually using wrenches or screwdrivers with bolts and nuts to install the generator onto the airbag housing and connect it to the airbag. This process is cumbersome and time-consuming. Furthermore, if workers forget their tools, they cannot install, disassemble, or replace the airbag generator. Therefore, we propose an airbag generator installation component. Utility Model Content

[0004] The purpose of this invention is to provide an airbag generator mounting assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an airbag generator mounting assembly, comprising:

[0006] The box body has an airbag inflation port on its top.

[0007] The generator has an external mounting plate:

[0008] The mounting mechanism is located between the housing and the generator, and can automatically lock the generator and the housing when the generator comes into contact with the air bladder inflation port on the top of the housing.

[0009] A reset mechanism is provided on the top of the housing. When the generator is released from the housing, the reset mechanism can automatically pop the generator up and separate it from the housing.

[0010] Preferably, the installation mechanism includes several fixed sleeves disposed on the top of the box, a sliding sleeve disposed on the side wall of the fixed sleeve and communicating with its interior, several fixed posts disposed on the bottom of the installation plate corresponding to the fixed sleeve, a limiting post slidably disposed inside the sliding sleeve and extending into the fixed sleeve, and a first spring disposed between the limiting post and the inner wall of the sliding sleeve, wherein the outer wall of the fixed post is provided with a limiting groove that cooperates with the limiting post.

[0011] Preferably, the installation mechanism further includes a bolt threaded to the side wall of the slide sleeve and an elastic rope disposed between the bolt's screw-in end on the inner side of the slide sleeve and the limiting post.

[0012] Preferably, the bottom end of the fixing post and the end of the limiting post facing the inside of the fixing sleeve have a matching arc shape structure.

[0013] Preferably, the reset mechanism includes a fixed cylinder disposed on the top of the box body, a slide rod slidably disposed inside the fixed cylinder, and a second spring disposed between the bottom of the slide rod and the bottom wall of the fixed cylinder, and the side wall of the mounting plate is provided with a protrusion that cooperates with the slide rod.

[0014] Preferably, a sealing sleeve is provided on the outside of the air inlet at the top of the box, and a sealing gasket that mates with the sealing sleeve is provided on the outer wall of the generator located below the mounting plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] Example 1,

[0030] An airbag generator mounting assembly includes:

[0031] Box 1, with an airbag inflation port on the top of Box 1. Generator 2 is installed in the inflation port on the top of Box 1, which can inflate the airbag inside Box 1 when Generator 2 is impacted.

[0032] Generator 2 has an external mounting plate 3. By quickly fixing the mounting plate 3 to the top of the housing 1, generator 2 can be installed.

[0033] The mounting mechanism 4 is located between the housing 1 and the generator 2. When the generator 2 and the air inlet of the top airbag of the housing 1 come into contact, the mounting mechanism 4 can automatically lock the generator 2 and the housing 1. When it is necessary to install the generator 2 on the housing 1, simply press the generator 2 into the air inlet at the top of the housing 1, and the mounting mechanism 4 can quickly and automatically lock the generator 2 and the housing 1.

[0034] The reset mechanism 5 is located on the top of the housing 1. When the generator 2 is released from the housing 1, the reset mechanism 5 can automatically pop the generator 2 up and separate it from the housing 1. When the generator 2 and the housing 1 are released by the installation mechanism, the reset mechanism 5 can quickly pop the generator 2 up, thereby improving the disassembly speed of the generator 2 and the housing.

[0035] The mounting mechanism 4 includes several fixed sleeves 401 disposed on the top of the housing 1, sliding sleeves 402 disposed on the side wall of the fixed sleeves 401 and connected to the inside therein, several fixed posts 403 disposed on the bottom of the mounting plate 3 corresponding to the fixed sleeves 401, limiting posts 404 slidably disposed inside the sliding sleeves 402 and extending into the fixed sleeves 401, and a first spring 405 disposed between the limiting posts 404 and the inner wall of the sliding sleeves 402. The outer wall of the fixed posts 403 is provided with a limiting groove 4031 that cooperates with the limiting posts 404.

[0036] When the airbag generator 2 needs to be installed, first position the generator 2 against the inflation port on the top of the housing 1 and press it into the inflation port. At this time, the fixing posts 403 at the bottom of the mounting plate 3 will be inserted into the fixing sleeve 401 on the top of the housing 1. When the fixing post 403 contacts the limiting post 404, it will squeeze the limiting post 404 into the sliding sleeve 402 and compress the first spring 405. When the generator 2 is fully pressed into the inflation port, the fixing post 403 will also be fully inserted into the fixing sleeve 401. At this time, the limiting groove 4031 on the side wall of the fixing post 403 will be on the same plane as the limiting post 404. Therefore, the first spring 405 will be released and the limiting post 404 will rebound and insert into the limiting groove 4031 to lock the fixing post 403. Thus, the generator 2 can be quickly installed on the housing 1. The operation is simple and saves time.

[0037] The bottom end of the fixing post 403 and the end of the limiting post 404 facing the inside of the fixing sleeve 401 are mutually cooperating arc-shaped structures. When the bottom of the fixing post 403 and the limiting post 404 are in contact at one end inside the fixing sleeve 401, the mutually cooperating arc-shaped ends facilitate the fixing post 403 to stably squeeze the limiting post 404 into the sliding sleeve 402.

[0038] In addition, a sealing sleeve 6 is provided on the outer side of the air inlet at the top of the box 1, and a sealing gasket 7 that mates with the sealing sleeve 6 is provided on the outer wall of the generator 2 located below the mounting plate 3. The bottom of the sealing gasket 7 is an inverted T-shaped structure, and the inside of the sealing sleeve 6 is provided with an inverted T-shaped sealing groove that mates with the sealing gasket 7. After the generator 2 is installed, the sealing gasket 7 on its outer side will be inserted into the sealing sleeve 6 at the top of the box 1, thereby improving the sealing performance of the connection between the generator 2 and the air inlet at the top of the box 1. Furthermore, the sealing performance of the connection between the generator 2 and the air inlet of the box 1 can be further improved by the sealing gasket 7 with its inverted T-shaped bottom being inserted into the inverted T-shaped groove inside the sealing sleeve 6.

[0039] According to the above embodiments, Embodiment Two

[0040] The mounting mechanism 4 also includes a bolt 406 threaded to the side wall of the sleeve 402 and an elastic rope 407 disposed between the screw end of the bolt 406 located inside the sleeve 402 and the limiting post 404.

[0041] When it is necessary to remove the generator 2 from the housing 1, simply unscrew the bolt 406 from the sliding sleeve 402, and then pull the limiting post 404 with the elastic rope 407 to pull the limiting post 404 back into the sliding sleeve 402 and disengage it from the limiting groove 4031. At this time, the fixing post 403 is released, and the generator 2 can be removed from the housing 1.

[0042] It should be noted that the reset mechanism 5 includes a fixed cylinder 501 disposed on the top of the box body 1, a slide rod 502 slidably disposed inside the fixed cylinder 501, and a second spring 503 disposed between the bottom of the slide rod 502 and the inner bottom wall of the fixed cylinder 501. The side wall of the mounting plate 3 is provided with a protrusion 301 that cooperates with the slide rod 502.

[0043] When the generator 2 is pressed into the air inlet at the top of the housing 1 for installation, the protrusion 301 on the side wall of the mounting plate 3 will squeeze the slide rod 502 to slide into the fixed cylinder 501 and compress the second spring 503. When the limiting post 404 is pulled to disengage from the limiting groove 4031 and the fixed post 403 is released, the second spring 503 will be released and the slide rod 502 will bounce upward and reset. This allows the generator 2 with the mounting plate 3 to be quickly lifted and separated from the housing 1, thereby increasing the speed of disassembling the generator 2.

[0044] The mounting plate 3 has evenly distributed anti-slip grooves 302 engraved on its outer wall. The mounting plate 3 with anti-slip grooves 302 makes it easy for personnel to steadily pick up and drop the generator 2.
