Description

Technical Field

[0001] This utility model relates to the technical field of automotive airbags, specifically a quick-change clamping device for multi-specification compatible airbag gas generators. Background Technology

[0002] All cars need to be equipped with airbags. Airbags are mainly used to prevent injuries caused by collisions between occupants and interior components during a car crash. During the production of car airbags, the gas generator is a core component, and its assembly precision directly affects the airbag deployment speed and safety. When a single person installs the gas generator, because the gas generator is cylindrical, it will roll on the inclined surface of the fixed base, making it difficult to control when installed by a single person.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN219687261U, Publication Date 2023-09-15) provides a head airbag generator fixing device. By incorporating a clamping device, the gas generator is clamped between two clamping plates before installation. This facilitates faster installation of the gas generator onto the fixed base, greatly improving work efficiency and reducing the workload for the workers.

[0004] The above solution clamps and fixes the gas generator by moving the clamping plate relative to the gas generator during use. The curvature of the clamping plate is fixed. However, when fixing gas generators of different diameters, the fixed curvature is not enough to fit and contact the outside of the gas generator. As a result, the stability of gas generators of different specifications varies after installation, which will affect the use of the airbag and pose a safety hazard to the driver. Utility Model Content

[0005] The purpose of this invention is to provide a quick-change clamping device for multi-specification adaptable airbag gas generators, in order to solve the problem mentioned in the background art. In the process of use, the existing airbag gas generator clamping device clamps and fixes the gas generator by relative movement of the clamping plate. The curvature of the clamping plate is fixed. However, when fixing gas generators of different diameters, the fixed curvature is not enough to fit and contact the outside of the gas generator. As a result, the firmness of gas generators of different specifications varies after installation, which affects the use of airbags and poses a safety hazard to the driver.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change clamping device for multi-specification adaptable airbag gas generators, including a base, mounting plates provided on the front and rear sides of the base, the mounting plates being connected to the vehicle mounting parts, transverse grooves symmetrically provided on the left and right sides of the top of the base, a first slider being slidably connected in the transverse grooves, a column being fixedly installed on the top of the first slider, and a clamping plate being installed in the middle of the opposite face of the two columns, the clamping plate holding the gas generator body.

[0007] The clamping plate has connecting rods hinged to the outer sides of its top and bottom, and a second slider is hinged to the outer side of the connecting rod. The second slider is slidably connected in a vertical groove, which is symmetrically opened on the opposite surfaces of the column.

[0008] The clamping plate is symmetrically slidably connected to the front and rear sides of the clamping plate, and the abutting plates abut and clamp the front and rear sides of the gas generator body.

[0009] Furthermore, a first reverse screw is rotatably connected in the top horizontal groove of the mounting plate, and the right side of the first reverse screw is connected through to the outside of the base. A first slider is threaded onto the first reverse screw.

[0010] Furthermore, the first slider drives the columns and clamping plates on both sides to move relative to each other via the first reverse lead screw, and the threads of the first sliders on both sides have opposite directions.

[0011] Furthermore, a second reverse screw is rotatably connected in the vertical groove on the side of the column, and the top of the second reverse screw is connected through to the top of the column. The second slider forms a vertical sliding structure with the vertical groove through the second reverse screw.

[0012] Furthermore, the threads of the second slider on the upper and lower sides are opposite. After the second slider moves, the curvature of the clamping plate is adjusted by the connecting rod to adapt it to the gas generator body of different specifications.

[0013] Furthermore, a limiting groove is formed through the middle of the clamping plate, and sliding rods are slidably connected to the front and rear sides of the limiting groove. An abutment plate is fixed to the outside of the sliding rods, and a connecting spring is connected between the sliding rods.

[0014] Furthermore, the contact plate is configured as a front-to-back contact clamping structure by means of a sliding rod and a connecting spring, and the contact plate is configured as a fan-shaped structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This multi-size compatible quick-change clamping device for airbag gas generators allows for easy and rapid replacement of gas generators by adjusting the arc size of the clamping plate according to the specific size of the gas generator. The clamping plate also engages with the front and rear sides of the gas generator for auxiliary clamping, improving its practicality and stability.

[0017] 1. Furthermore, when clamping gas generators of different specifications, after the clamping plates move relative to each other, it is necessary to adjust the curvature of the clamping plates. By rotating the second reverse screw on the column, the second reverse screw will drive the second slider to move relative to each other in the vertical groove. After the second slider moves, it will drive the top and bottom of the clamping plate to unfold or close through the connecting rod, thereby adaptively adjusting the curvature of the clamping plate so that it can be adapted to multiple specifications of gas generators, better fit the outside of the gas generator, and improve clamping stability.

[0018] 2. Furthermore, after the clamping plate fixes the gas generator, the front and rear abutment plates are pulled to make them abut against the front and rear sides of the gas generator. After the abutment plates are pulled, they will drive the slide rod to slide in the limiting groove, thereby stretching the connecting spring. At the same time, the tension of the connecting spring will also make the abutment plates better abut against the front and rear sides of the gas generator, further improving the positioning effect of the clamping device.

[0028] In use, the base 1 is connected and fixed to the corresponding mounting part on the car through the mounting plate 2. After the first slider 5 slides relative to the horizontal groove 3, it drives the column 6 to move synchronously. The clamping plate 7 on the column 6 will clamp and fix the gas generator body 12.

[0029] Example 2:

[0030] Based on Embodiment 1, a first reverse lead screw 4 is also disclosed; please refer to [reference needed]. Figures 1-3 As shown, its specific structure is as follows: The outer sides of the top and bottom of the clamping plate 7 are hinged with connecting rods 8, and the outer sides of the connecting rods 8 are hinged with second sliders 9. The second sliders 9 are slidably connected in the vertical grooves 10. The vertical grooves 10 are symmetrically opened on the opposite surfaces of the columns 6. The first reverse screw 4 is rotatably connected in the horizontal groove 3 at the top of the mounting plate 2. The right side of the first reverse screw 4 is connected through to the outer side of the base 1. The first slider 5 is threadedly connected to the first reverse screw 4. The first slider 5 drives the columns 6 and the clamping plate 7 on both sides to move relative to each other through the first reverse screw 4. The threads of the first sliders 5 on both sides are opposite.

[0031] When in use, after rotating the first reverse screw 4 on the base 1, the first reverse screw 4 drives the first slider 5 to move in the transverse groove 3. The first slider 5 drives the clamping plate 7 to move relative to each other through the column 6, thereby positioning and fixing the gas generator body 12. When clamping gas generator bodies 12 of different specifications, after the clamping plate 7 moves relative to each other, it is also necessary to adjust the unfolding arc of the clamping plate 7.

After the second slider 9 moves, the curvature of the clamping plate 7 is adjusted by the connecting rod 8 to adapt it to the gas generator body 12 of different specifications.

[0033] In use, rotating the second reverse screw 11 on the column 6 will cause the second slider 9 to move relative to the vertical groove 10. After the second slider 9 moves, it will cause the top and bottom of the clamping plate 7 to expand or converge through the connecting rod 8, thereby adaptively adjusting the curvature of the clamping plate 7 so that it can fit the gas generator body 12 of various specifications, better fit the outside of the gas generator body 12, and improve the clamping stability.
