Description

Technical Field

[0001] This utility model relates to the field of airbag testing technology, and in particular to an airbag assembly testing device. Background Technology

[0002] In the automotive manufacturing industry, airbags, as crucial safety devices, require folding and installation testing before being installed in vehicles to ensure they function properly in emergencies and provide effective protection for passengers. However, current airbag assembly compatibility testing primarily relies on manual operation, which presents numerous problems.

[0003] Traditional inspection methods primarily rely on visual inspection and manual measurement by inspectors. Inspectors must observe the folded shape of the airbag and use a steel ruler to measure the length and position of the fixing bolts. This method demands extremely high concentration from personnel and is prone to fatigue during prolonged work, making it difficult to fully identify product defects and posing a significant risk of missed inspections. Furthermore, due to the complexity and diversity of airbag folding methods and forces, manual inspection struggles to guarantee the accuracy and consistency of results, leading to a high error rate.

[0004] In terms of testing efficiency, current methods are time-consuming and labor-intensive, making it difficult to meet the demands of modern automotive production lines for efficient and stable testing processes. Therefore, existing airbag assembly testing methods suffer from objective drawbacks such as low operational efficiency, low accuracy, and high error rates, necessitating a testing device that can improve testing efficiency and accuracy while reducing error rates.

[0005] In view of the problems existing in the prior art, the present invention provides an airbag assembly testing device, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] According to one aspect of the present invention, the device includes: a movable compartment and a fixed compartment. The movable compartment is used to house an airbag assembly and is movably disposed at one end of the fixed compartment. The lower end of the movable compartment is provided with a plurality of detection holes, and a first sensing device is disposed below the plurality of detection holes. The first sensing device is used to detect the fasteners of the airbag assembly. The front and rear ends of the movable compartment are respectively formed with first openings for exposing the airbag assembly. The front and rear ends of the fixed compartment are equipped with second sensing devices for detecting the tension of the airbag assembly, and the upper end of the fixed compartment is provided with a detection window.

[0008] Furthermore, it also includes a base plate, a first connecting seat, at least one connecting rod, and a second connecting seat. The base plate is fixed to the lower end of the fixed compartment, and one end of the base plate extends along the length direction. The first connecting seat and the second connecting seat are fixedly disposed at intervals on the upper end of the base plate. The movable compartment also includes a base. The connecting rod passes through the first connecting seat, the base, and the second connecting seat.

[0009] Furthermore, the active compartment also includes at least two side plates, which are symmetrically arranged at the left and right ends of the base, and the left and right ends of the airbag assembly abut against the two side plates.

[0010] Furthermore, a handle is fixedly provided at one end of the movable compartment.

[0011] Furthermore, the first sensing device is a piezoelectric thin film sensor, and a gap is formed between the plurality of detection holes and the piezoelectric thin film sensor.

[0012] Furthermore, the second sensing device is a tension meter, and the fixed chamber includes at least two detection plates, which are respectively located at the front and rear ends of the fixed chamber, and the measuring sensing element of the tension meter is respectively mounted on the two detection plates.

[0013] Furthermore, the fixed chamber also includes a baffle plate, which is fixed between the two detection plates and is located at the right end of the fixed chamber.

[0014] Furthermore, the positions of some of the detection holes correspond to the positions of the fasteners of the airbag assembly.

[0015] Furthermore, the fastener is a bolt.

[0016] Furthermore, the position of the detection window corresponds to the fold at the upper end of the airbag assembly.

[0017] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] The testing device of this invention can quickly complete multiple tests on the airbag assembly through the cooperation of the movable and fixed chambers, as well as automated testing components such as piezoelectric film sensors and tension meters, which significantly improves the testing efficiency. It uses piezoelectric film sensors to detect the length and position of bolts and uses tension meters to measure the tension on the side of the airbag, presenting the test results in specific numerical form. This avoids the instability and subjectivity of manual measurement, greatly improves the accuracy and consistency of the test results, effectively reduces the error rate caused by human factors, and ensures that the quality of each airbag assembly can be accurately evaluated.

[0019] This testing device limits the flatness of the left and right sides of the airbag through the side panel of the movable compartment, corrects the flatness of the upper side of the airbag through the structure of the fixed compartment, and checks the folding method of the top of the airbag through the inspection window, and judges the folding state by measuring the side tension through the tension meter. It realizes all-round and multi-angle inspection of the airbag assembly, ensuring that the folding shape and installation fit of the airbag fully meet the installation requirements of the automotive assembly module, and further improves the inspection quality.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] like Figures 1 to 4 As shown, this solution provides a safety airbag assembly testing device.

[0028] Please see Figures 1 to 4 The system includes a movable compartment 1 and a fixed compartment 2. The movable compartment 1 is used to house the airbag assembly (not shown). The movable compartment 1 is movably positioned at one end of the fixed compartment 2, and specifically, it also includes a base plate 5, a first connecting seat 3, at least one connecting rod 4, and a second connecting seat 7. The base plate 5 is fixed to the lower end of the fixed compartment 2, and one end of the base plate 5 extends along its length. The first connecting seat 3 and the second connecting seat 7 are fixedly positioned at the upper end of the base plate 5 at intervals. The movable compartment 1 also includes a base 11. The connecting rod 4 passes through the first connecting seat 3, the base 11, and the second connecting seat 7. In this embodiment, there are two connecting rods 4, which are spaced apart and pass through the first connecting seat 3, the base 11, and the second connecting seat 7. The movable compartment 1 can move left and right through the two connecting rods 4.

[0029] Please see Figures 1 to 4 The lower end of the movable compartment 1 is provided with several detection holes 15. Below these detection holes 15 is a first sensing device 8, which is used to detect the fasteners of the airbag assembly. The first sensing device 8 is a piezoelectric thin-film sensor, and a gap is formed between the detection holes 15 and the piezoelectric thin-film sensor. The positions of the detection holes 15 correspond to the positions of the fasteners of the airbag assembly. The fasteners are bolts. The piezoelectric thin-film sensor is a direct application of existing technology, and its principle will not be elaborated here. In this embodiment, there are four detection holes 15, which are respectively located on the base 11, and their positions correspond to the positions of the bolts in the airbag assembly. All four bolts of the airbag assembly to be tested pass through the detection holes 15 of the movable compartment 1 and contact the piezoelectric thin-film sensor below. The piezoelectric thin-film sensor will trigger a corresponding indication signal, indicating that the bolt detection is qualified; otherwise, it indicates that the bolt detection is unqualified.

[0030] Please see Figures 1 to 4 The movable compartment 1 has first openings 13 at its front and rear ends for exposing the airbag assembly. The movable compartment 1 also includes at least two side plates 12, symmetrically arranged at the left and right ends of the base 11, with the left and right ends of the airbag assembly abutting against the side plates 12. A handle 14 is fixed to one end of the movable compartment 1. Specifically, the handle 14 is fixed to one of the side plates 12.

[0031] Please see Figures 1 to 4 The fixed compartment 2 is equipped with second sensing devices 6 at its front and rear ends for detecting the tension of the airbag assembly. These second sensing devices 6 are tension gauges. Specifically, the fixed compartment 2 includes at least two detection plates 21, located at its front and rear ends respectively. The measuring sensing elements of the tension gauge are respectively mounted on the two detection plates 21. The tension gauge is a strain gauge. The tension gauge is a direct application of existing technology, and its principle will not be elaborated here.

[0032] Please see Figures 1 to 4 The fixed compartment 2 has a detection window 22 at its upper end. The position of the detection window 22 corresponds to the folding part at the upper end of the airbag assembly. A second opening 20 is formed at the left end of the fixed compartment 2, through which the movable compartment 1 enters the fixed compartment 2. The fixed compartment 2 also includes a baffle 23, which is fixed between the two detection plates 21 and is located at the right end of the fixed compartment 2.

[0033] Working principle:

[0034] This airbag assembly testing device achieves comprehensive testing of the airbag assembly through the coordinated operation of components such as the movable chamber 1, the fixed chamber 2, the first sensing device 8, and the second sensing device 6.

[0035] During operation, first place the folded airbag assembly, bolt side down, into the movable compartment 1, ensuring that the left and right ends of the airbag assembly abut against the side panels 12 of the movable compartment 1. At this time, the bolts at the lower end of the airbag assembly correspond to the detection holes 15 on the movable compartment base 11. Several detection holes 15 at the lower end of the movable compartment 1 are equipped with piezoelectric thin-film sensors. The bolts of the airbag assembly pass through the detection holes 15 of the movable compartment 1 and contact the piezoelectric thin-film sensors below. If the bolt is correctly positioned and its length meets the requirements, the piezoelectric thin-film sensor will trigger a corresponding indication signal, indicating that the bolt has passed the inspection. If the bolt is too long, it cannot enter the fixed compartment 2. If the bolt is too short or incorrectly positioned, the piezoelectric thin-film sensor will not issue an indication signal; both of these situations indicate that the bolt inspection has failed.

[0036] Next, push the movable compartment 1 to allow the airbag assembly to enter the fixed compartment 2. The airbag assembly will compress the detection plates 21 on both sides of the fixed compartment 2. The tension gauge can detect the tension on the side of the airbag assembly and display the tension value on the display screen. The operator can judge whether the side folding state of the airbag is appropriate based on the value.

[0037] In addition, the detection window 22 at the upper end of the fixed compartment 2 corresponds to the folding part at the upper end of the airbag assembly. After the airbag assembly enters the fixed compartment 2, the operator can visually observe whether the folding method of the top of the airbag is correct through the detection window 22.

[0038] Once the test is complete, push the movable compartment 1 in the reverse direction so that it moves out of the fixed compartment 2 along the connecting rod 4, and remove the airbag assembly to complete a full test process.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
