The mounting holes 121 are used for mounting the airbag 11 at a predetermined position of the vehicle body, and the support plates 122 are used for supporting the airbag 11. Figure 1 and Figure 2 As shown in the figure, the airbag bracket 12 is provided with two mounting holes 121 and two support plates 122, but it is not limited thereto. The number and distribution of the mounting holes 121 and the support plates 122 can be set according to the mounting and supporting requirements of the airbag 11.
[0032] Figure 3 schematic structure of the detection device in the initial position is shown, Figure 4 schematic structure of the detection pin of the detection device moving to the position is shown, Figure 5 schematic structure of the detection fork of the detection device moving to the position is shown, Figure 6 schematic structure of the detection device detecting the mounting holes and the support plates of the airbag bracket is shown; as shown in the figure, Figures 1 to 6 The detection device provided by the utility new type embodiment comprises:
[0033] The bearing tool 20 is used for bearing the airbag assembly 10 containing the airbag bracket 12;
[0034] The first detection assembly 30 comprises a first driving mechanism 31 and a detection pin 32 connected with the first driving mechanism 31. The first driving mechanism 31 can drive the detection pin 32 to move towards the mounting hole 121.
[0035] The second detection assembly 40 is connected with the first driving mechanism 31, and the second detection assembly 40 comprises a second driving mechanism 41 and a detection fork 42 connected with the second driving mechanism 41, and the second driving mechanism 41 can drive the detection fork 42 to move towards the support plate 122.
[0036] The airbag support 12 and the airbag assembly 10 formed by assembling the airbag 11 are mounted on the carrying tool 20. The detection pin 32 is driven by the first driving mechanism 31 to move towards the mounting hole 121, so that the position of the mounting hole 121 can be detected, and it is ensured that the airbag 11 is accurately mounted on the vehicle body. The detection fork 42 is driven by the second driving mechanism 41 to move towards the support plate 122, so that the position of the support plate 122 can be detected, and it is ensured that the airbag 11 is stably supported. The second detection assembly 40 is connected with the first driving mechanism 31, and the first driving mechanism 31 drives the detection pin 32 to move towards the mounting hole 121, and the second detection assembly 40 can be driven by the first driving mechanism 31 to move towards the airbag support 12 to a predetermined position, so that the second driving mechanism 41 drives the detection fork 42 to move towards the support plate 122, and thus the first driving mechanism 31 and the second driving mechanism 41 only need to operate once, respectively, to drive the detection pin 32 and the detection fork 42 to detect the position of the mounting hole 121 and the support plate 122.
[0037] The detection device of the utility model can detect the position of the airbag support 12 conveniently and accurately when the airbag support 12 and the airbag 11 are assembled, avoid the unqualified products from flowing out, and ensure the accurate installation of the airbag assembly 10.
[0038] In some embodiments, the first driving mechanism 31 is mounted on the first sliding rail 33, and the extension direction of the first sliding rail 33 is parallel to the axis Z of the mounting hole 121. Thus, the first driving mechanism 31 can drive the detection pin 32 to move along the axis Z of the mounting hole 121, so as to detect the position of the mounting hole 121.
[0039] In some embodiments, the outer diameter of the detection pin 32 is smaller than the inner diameter of the mounting hole 121, and the detection pin 32 can extend into the mounting hole 121 without interfering with the mounting hole 121. Figure 2 、 Figure 4 and Figure 6 As shown in the figures, in an ideal case, the detection pin 32 extends into the mounting hole 121 under the driving of the first driving mechanism 31, and does not interfere with the mounting hole 121, such as scratching, indicating that the position and hole diameter of the mounting hole meet the design requirements. In the case where the mounting hole 121 comprises two or more mounting holes, the number of detection pins 32 corresponds to the number of mounting holes 121, and the detection pin 32 is also used to detect whether the hole diameter between the mounting holes 121 meets the design requirements.
[0040] In some embodiments, the first driving mechanism 31 comprises a first cylinder and an operation handle 310 for controlling the first cylinder to release air. As shown in Figure 2 , Figures 4 to 6 When the first driving mechanism 31 drives the detection pin 32 to move to a position, the operation handle 310 is pulled to release air of the first cylinder to keep the position of the detection pin 32, at which time the positional relationship between the detection pin 32 and the mounting hole 121 can be observed to determine whether the position of the mounting hole 121 meets the design requirement; then, the switch of the second driving mechanism 41 is started to drive the detection fork 42 to move towards the support plate 122 to detect whether the position of the support plate 122 meets the design requirement.
[0041] In some embodiments, the second driving mechanism 41 is installed on a second sliding rail 43, and the extension direction of the second sliding rail 43 is parallel to the plane of the support plate 122. In this way, the detection fork 42 can be driven by the second driving mechanism 41 to move along the plane of the support plate 122 to detect the position of the support plate 122.
[0042] In some embodiments, the detection fork 42 is in the shape of n, the groove width of the detection fork 42 is greater than the thickness of the support plate 122, and the detection fork 42 can clamp the support plate 122 without interference with the support plate 122. As shown in Figure 2 , Figure 5 and Figure 6 Ideally, the detection fork 42 is driven by the second driving mechanism 41 to move towards the support plate 122 to clamp the support plate 122 without interference such as scratching, which indicates that the position and flatness of the support plate 122 meet the design requirement. In the case where the support plate 122 comprises more than two, the number of detection forks 42 corresponds to the number of support plates 122 to detect whether the position of each support plate 122 meets the design requirement.
[0043] In some embodiments, the second driving mechanism 41 comprises a second cylinder. Through the second cylinder, the detection fork 42 can be accurately driven to move to a position.
[0044] Further, in some embodiments, the detection pin 32 and the first driving mechanism 31, and the detection fork 42 and the second driving mechanism 41 are respectively detachably connected. In this way, according to the design requirement of the airbag support 12 to be detected, the appropriate detection pin 32 and detection fork 42 can be adjusted and replaced to adapt to various airbag supports 12 to accurately detect the position of the mounting hole 121 and the support plate 122 of the airbag support 12.
[0045] The above is further detailed description of the utility model in combination with specific preferred embodiments, and cannot be deemed as limitation of the specific implementation of the utility model to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, and all of them shall be deemed as belonging to the protection scope of the utility model.
