Description

Technical Field

[0001] This disclosure relates to the field of airbag testing technology, and more specifically to an airbag detonation testing device and an airbag detonation testing system. Background Technology

[0002] In the existing technology, there are environmental chambers for airbag detonation testing. These environmental chambers can simulate various temperature conditions, support high temperature, low temperature and room temperature detonation tests, and the temperature range can generally reach -40℃ to 100℃. They can also achieve a temperature change rate of 2.0℃ / min.

[0003] To transport the mobile platform into the environmental chamber, a transport device is typically required. This device usually needs to quickly move the vehicle body, weighing up to 1 ton, into the environmental chamber for insulation treatment, and it should also be capable of automatically towing the mobile platform. For environmental chambers used for airbag deployment testing, there is an urgent need for a solution that can achieve stable towing and transport of the mobile platform. Utility Model Content

[0004] The purpose of this disclosure is to provide an airbag detonation testing device that enables stable and reliable traction and transportation of a mobile platform.

[0005] Another object of this disclosure is to provide an airbag detonation testing system including the airbag detonation testing device.

[0006] Therefore, one aspect of this disclosure relates to an airbag deployment testing device configured for conducting deployment tests on airbags installed in a vehicle, wherein the vehicle is placed on a mobile platform. The airbag deployment testing device comprises: an environmental chamber configured to regulate the temperature inside the environmental chamber so that the airbag can deploy at a defined temperature; and a transport device configured to transport the mobile platform within the airbag deployment testing device, the transport device including a support and guiding mechanism and a traction mechanism, wherein the support and guiding mechanism extends from a first external region connected to the environmental chamber into the environmental chamber and is configured to support and guide the mobile platform along the airbag deployment testing device. The longitudinal direction of the device extends over the area of ​​the environmental chamber and the area outside the first chamber, and the traction mechanism is configured to traction the mobile platform along the support and guide mechanism to move the mobile platform carrying the vehicle into the environmental chamber. The traction mechanism includes a plurality of gear transmission mechanisms spaced apart from each other and each having a rotatable output gear. The gear transmission mechanisms are configured to engage their output gears with a rack below the mobile platform and to traction the mobile platform along the support and guide mechanism by rotating the output gears. At least one first gear transmission mechanism is arranged in the area outside the first chamber, and a plurality of second gear transmission mechanisms are arranged inside the environmental chamber.

[0007] In this disclosure, by setting multiple gear transmission mechanisms that are spaced apart from each other and each has a rotatable output gear, the moving platform can be moved one after another by these gear transmission mechanisms. During the traction process, the gear transmission mechanisms operate smoothly and with high working accuracy, achieving stable and reliable traction and transportation. In particular, compared with chain traction in existing technologies, traction and transportation using multiple gear transmission mechanisms is better in terms of accuracy and smoothness.

[0008] In some embodiments, the support and guide mechanism extends into a second outer region adjacent to or overlapping with the first outer region, and extends longitudinally into the second outer region. This allows the mobile platform carrying the vehicle to be placed on the support and guide mechanism in the second outer region or towed by a towing mechanism from the environmental chamber to the support and guide mechanism located in the second outer region, thereby enabling the airbags in the vehicle to be deployed in the second outer region. Thus, in the "same-in, same-out" mode of the mobile platform, in addition to deployment within the environmental chamber, it is possible to perform ambient temperature deployment in the second outer region without having entered the environmental chamber, and to perform external deployment after experiencing temperature changes within the environmental chamber and then re-entering the second outer region.

[0009] In some embodiments, the support and guide mechanism extends into a third outer-box region opposite to and connected to the environmental box, and extends longitudinally in the third outer-box region. This allows the mobile platform carrying the vehicle to be towed by a traction mechanism from the environmental box to the support and guide mechanism located in the third outer-box region, thereby enabling the airbags in the vehicle to be deployed in the third outer-box region. This allows for a "forward-backward-outward" mode of the mobile platform, in which, in addition to deployment within the environmental box, it is possible to perform both ambient-temperature external deployment in the second outer-box region without having entered the environmental box and external deployment in the third outer-box region after experiencing temperature changes within the environmental box.

[0010] In some embodiments, at least one third gear transmission mechanism is arranged in the area outside the third gearbox.

[0011] In some implementations, the distance between the centers of two adjacent gear transmission mechanisms is less than the length of the rack below the moving platform.

[0012] In some implementations, the distance between the centers of any two adjacent second gear transmission mechanisms is less than or equal to 2m.

[0013] In some implementations, the distance between the centers of any two adjacent second gear transmission mechanisms is less than or equal to 1m.

[0014] In some embodiments, the plurality of gear transmission mechanisms each have a transmission housing that is connected to the output gear, and the traction mechanism includes a drive shaft that passes through the respective transmission housing of each gear transmission mechanism and is configured to transmit the motion of the drive shaft to the output gear of each gear transmission mechanism. Thus, synchronous rotation of the corresponding output gears in each gear transmission mechanism can be achieved using a single drive shaft.

[0015] In some embodiments, the drive shaft is configured as a drive screw.

[0016] In some embodiments, within the environmental chamber, a 1:1 gear reducer is arranged on the drive shaft between every two second gear transmission mechanisms, achieving a 1:1 transmission ratio. This allows for concentric positioning via the 1:1 gear reducer and prevents accuracy degradation due to concentricity shifts during drive shaft operation.

[0017] In some implementations, the corresponding 1:1 transmission reducer is positioned at the center between two adjacent second gear transmission mechanisms. This achieves good positioning and concentricity.

[0018] In some embodiments, the traction mechanism includes a drive unit disposed outside the environmental chamber, which drives the drive shaft. This allows the drive shaft to rotate from outside the environmental chamber via the drive unit, thereby preventing damage to the drive unit caused by the extreme temperatures inside the environmental chamber.

[0019] In some embodiments, the drive unit is arranged in the area outside the first housing. This allows for an advantageous arrangement of the drive unit.

[0020] In some embodiments, the support and guide mechanism includes two parallel guide rails extending longitudinally.

[0021] In some embodiments, the support and guiding mechanism further includes a guide rail bracket in the corresponding outer area of ​​the housing, with the corresponding guide rail fixedly supported on the guide rail bracket. This provides advantageous support for the guide rail.

[0022] In some embodiments, protrusions are provided along the upper surfaces of the two guide rails, respectively. These protrusions are configured to engage with the U-shaped sliding wheels of the mobile platform to guide its movement. This allows for advantageous guidance of the mobile platform.

[0023] In some embodiments, a buffer is arranged in the corresponding external area of ​​the enclosure at the end of the support and guide mechanism away from the environmental enclosure to cushion the movement of the mobile platform as it moves out of the environmental enclosure. This ensures the safe stopping of the mobile platform during rapid exit from the enclosure and reduces wear on the output gears and racks caused by sudden braking, thereby extending the service life of the output gears and racks and ensuring high precision over a long period.

[0024] Another aspect of this disclosure relates to an airbag deployment testing system, characterized in that the airbag deployment testing system includes an airbag deployment testing device according to any one of the foregoing embodiments and a mobile platform, the mobile platform being configured to receive a vehicle carrying an airbag and, while carrying the vehicle, move within the airbag deployment testing device via a transport device of the airbag deployment testing device, wherein a rack is provided on the mobile platform, the rack being configured to mesh with an output gear of a gear transmission mechanism. Thus, an output gear-rack engagement can be established between the mobile platform and the traction mechanism of the transport device to achieve smooth and high-precision transport.

[0025] In some embodiments, the rack is fixedly disposed below the mobile platform.

[0026] In some embodiments, the length of the rack is less than or equal to 4m.

[0027] In some embodiments, the length of the rack is less than or equal to 2m.

[0028] In some embodiments, the mobile platform has at least four U-shaped slide wheels below it, the slide wheels being configured to engage with the ridges on the guide rails with clearance.

[0029] In some embodiments, the slide wheel of the mobile platform and the rib of the guide rail are configured such that the gap between the slide wheel and the rib is between 2 mm and 5 mm.

[0030] The technical features mentioned above, those to be mentioned below, and those shown individually in the accompanying drawings can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features. Attached Figure Description

[0041] Firstly, by using Figures 1 to 4 An embodiment of the airbag detonation test apparatus 100 according to the present disclosure is described.

[0042] In this disclosure, the airbag deployment testing equipment 100 is configured to perform deployment tests on airbags installed in a vehicle, wherein the vehicle is placed on a mobile platform 200. Figure 1 and Figure 2 As shown, the airbag detonation testing equipment 100 includes: an environmental chamber 1 configured to regulate the internal temperature of the environmental chamber 1 so that the airbag can be detonated at a defined temperature; and a transport device configured to transport a mobile platform 200 within the airbag detonation testing equipment 100 (see [reference]). Figure 5 ), and the transport device includes a support and guide mechanism 2 and a traction mechanism, wherein the support and guide mechanism 2 extends from the first external area A1 connected to the environmental container 1 ( Figure 2 The dashed area extends into the environmental chamber 1 and is configured to support and guide the mobile platform 200. This support and guide mechanism 2 extends along the longitudinal direction of the airbag deployment test equipment 100 in the area of ​​the environmental chamber 1 and the first outer area A1. The traction mechanism is configured to traction the mobile platform 200 along the support and guide mechanism 2 to move the mobile platform 200 carrying the vehicle into the environmental chamber 1. The traction mechanism includes a plurality of gear transmission mechanisms 3, which are spaced apart from each other and each have a rotatable output gear 34. The gear transmission mechanisms 3 are configured to engage their output gears 34 with a rack 201 below the mobile platform 200 (see [link to equipment]). Figure 6 The moving platform 200 is moved along the support and guide mechanism 2 by rotating the output gear 34, wherein at least one first gear transmission mechanism 31 of the gear transmission mechanism 3 is arranged in the first outer box area A1, and a plurality of second gear transmission mechanisms 32 of the gear transmission mechanism 3 are arranged inside the environmental box 1. Furthermore, in this embodiment, the support and guide mechanism 2 extends to a second outer box area A2 that overlaps with the first outer box area A1. Figure 2The area shown in the dashed line, which is laterally offset from the first outer box area A1 for visibility reasons, and the support and guide mechanism 2 extends longitudinally over the second outer box area A2. Of course, in another embodiment, the second outer box area A2 may also be adjacent to the first outer box area A1—especially if separated by a small distance. Furthermore, the support and guide mechanism 2 extends to a third outer box area A3 that is opposite to and connected to the environmental box 1, relative to the first outer box area A1. Figure 2 In the dashed area, the support and guide mechanism 2 extends longitudinally in the third outer box area A3, wherein at least one third gear transmission mechanism 33 of the gear transmission mechanism 3 is arranged in the third outer box area A3. Thus, in this embodiment, the mobile platform 200 can achieve a "forward-backward" mode, allowing for selective detonation in the second outer box area A2 without entering the environmental box 1, or detonation in the third outer box area A3 after exiting the environmental box 1, in addition to detonation in the environmental box 1. Of course, besides this "forward-backward" mode, it is conceivable that in another embodiment, only the first outer box area A1 and the second outer box area A2 are provided, allowing for selective detonation in the second outer box area A2 without entering the environmental box 1, or detonation in the second outer box area A2 after exiting the environmental box 1, in a "same-in, same-out" mode. It should be noted that the dashed lines representing the corresponding outer box areas are merely exemplary and do not limit the actual coverage of the outer box areas.

[0043] In this embodiment, a total of six fixedly installed and spaced-apart gear transmission mechanisms 3 are provided. One gear transmission mechanism 3 is a first gear transmission mechanism 31 located in the first box outer area A1, four gear transmission mechanisms 3 are second gear transmission mechanisms 32 located in the environmental box 1, and the remaining gear transmission mechanism 3 is a third gear transmission mechanism 33 located in the third box outer area A3. The total coverage length of these six gear transmission mechanisms 3 is less than or equal to the total path length of 8m. For example, the length of the rack 201 under the mobile platform 200 can be 4m, and the distance between the centers of any two adjacent second gear transmission mechanisms 32 of the four gear transmission mechanisms 3 inside the environmental box 1 is 2m. Alternatively, the length of the rack 201 under the mobile platform 200 can be 2m, and the distance between the centers of any two adjacent second gear transmission mechanisms 32 of the four gear transmission mechanisms 3 inside the environmental box 1 is 1m.

[0044] To ensure synchronous rotation of the output gears 34 in each gear transmission mechanism 3, each of the plurality of gear transmission mechanisms 3 has a transmission housing 35 that is driveably connected to the output gear 34, and the traction mechanism includes a drive shaft 4 that passes through the corresponding transmission housing 35 of each gear transmission mechanism 3 and is configured to transmit the motion of the drive shaft 4 to the output gear 34 of each gear transmission mechanism 3. The drive shaft 4 is constructed as a drive screw and has a length of approximately 8 m.

[0045] To achieve concentric positioning and prevent accuracy degradation due to concentricity deviation during operation, a 1:1 transmission reducer 5 is arranged on the drive shaft 4 between every two second gear transmission mechanisms 32 within the environmental chamber 1. This 1:1 transmission reducer 5 can achieve a 1:1 transmission ratio (this 1:1 / 1:1 transmission reducer 5 can also be called a 1:1 transmission reducer). The corresponding 1:1 transmission reducer 5 is arranged at the center position between two adjacent second gear transmission mechanisms 32.

[0046] like Figure 3 As shown, the traction mechanism includes a drive unit 6, which is located outside the environmental chamber 1, for example, in the area A1 outside the first chamber. The drive unit 6 drives the transmission shaft 4, allowing each gear transmission mechanism 3 to be centrally driven by the drive unit 6 at the chamber entrance via the transmission shaft 4. The drive unit 6 is a high-load servo motor with a power of 10kW and is capable of both forward and reverse rotation. The drive unit 6 can be configured as a servo motor in conjunction with the first gear transmission mechanism 31. The drive unit 6 transmits the rotational motion of its output shaft to the output gear 34 of the first gear transmission mechanism 31 and the transmission shaft 4 connected to the transmission box 35 of the first gear transmission mechanism 31 via the transmission box 35, thereby driving the output gear 34 of all gear transmission mechanisms 3 to rotate.

[0047] The support and guiding mechanism 2 includes two parallel guide rails 21 extending longitudinally. In the respective outer regions of the housing, the support and guiding mechanism 2 also includes guide rail supports 22, on which the respective guide rails 21 are fixedly supported. On the upper surfaces of the two guide rails 21, respectively, are raised ribs 23, configured to cooperate with the U-shaped sliding wheels 202 of the moving platform 200 to guide the movement of the moving platform 200 (see [link]). Figure 8 ).

[0048] The following uses Figures 5 to 9This describes one embodiment of an airbag deployment testing system according to the present disclosure. The airbag deployment testing system includes an airbag deployment testing device 100 and a mobile platform 200 according to the above embodiment of the present disclosure. The mobile platform 200 is configured to receive a vehicle equipped with an airbag and, while carrying the vehicle, move within the airbag deployment testing device 100 via a transport device. A rack 201 is fixedly mounted below the mobile platform 200, the rack 201 being configured to mesh with an output gear 34 of a gear transmission mechanism 3. The length of the rack 201 is, for example, 4 m, preferably about 2 m. The mobile platform 200 has at least four U-shaped slide rails 202 below it, the slide rails 202 being configured to have a clearance fit with ribs 23 on guide rails 21. In this embodiment, as... Figure 7 As shown, four U-shaped slide wheels 202 are arranged on one side of the mobile platform 200, and four more U-shaped slide wheels 202 are arranged on the other side (not visible), thus the mobile platform 200 has eight slide wheels 202. These U-shaped slide wheels 202 cooperate with the protrusions 23 (also called contour grooves) on the guide rail 21, and the cooperation gap between the protrusions 23 and the slide wheels 202 is between 2mm and 5mm. The sliding resistance of a single slide wheel 202 does not exceed 25N.

[0049] To cushion the rapid unloading of the mobile platform 200, a buffer 7 is arranged at the end of the support and guide mechanism 2 facing away from the environmental box 1 in the corresponding external area of ​​the box (see...). Figure 9 This buffer is used to cushion the moving platform 200 as it moves out of the environmental chamber 1. This eliminates the need for deceleration or braking via the output gear 34 of the gear transmission mechanism 3, thus avoiding damage to the gear-rack structure. In this embodiment, a buffer 7 is arranged in the third outer chamber region A3 at the end of the support and guide mechanism 2 facing away from the environmental chamber 1. Alternatively, it is conceivable that a buffer 7 could also be arranged in the second outer chamber region A2 at the end of the support and guide mechanism 2 facing away from the environmental chamber 1.

[0050] Finally, by using Figure 9The operation flow of the mobile platform 200 in the airbag detonation test equipment 100 is described. When the mobile platform 200 is in its initial state, the rack 201 under the mobile platform 200 is engaged with the output gear 34 of the external first gear transmission mechanism 31, which is fixedly installed in the outer area A1 of the first housing. The first gear transmission mechanism 31 has a servo motor as a drive unit 6, which drives the output gear 34 of all gear transmission mechanisms 3 to rotate via the transmission box 35 of the first gear transmission mechanism 31. As the output gear 34 of the first gear transmission mechanism 31 rotates, the moving platform 200 reaches the internal second gear transmission mechanism 32 under the action of the first gear transmission mechanism 31. The distance between the first gear transmission mechanism 31 and the adjacent second gear transmission mechanism 32 is approximately 500mm (similarly, the distance between the third gear transmission mechanism 33 and the adjacent second gear transmission mechanism 32 is also approximately 500mm). As the moving platform 200 moves, the rack 201 below the moving platform 200 will sequentially mesh with the output gears 34 of the fixedly arranged second gear transmission mechanisms 32 and third gear transmission mechanisms 33 at different positions to perform transmission. After entering the environmental chamber 1, it can be brought into the third chamber outer area A3 by the third gear transmission mechanism 33 located in the third chamber outer area A3. In the case of rapid exiting the chamber, the moving platform 200 hits the buffer 7 for cushioning.

[0051] When using the airbag detonation test device 100 according to the present disclosure, which can realize the "forward and backward" mode, parallel testing of multiple test objects (airbags) set on multiple mobile platforms 200 can be realized. For example, at the same time, one mobile platform 200 can be located in the first box outside area A1, one mobile platform 200 can be located in the environmental box 1, and one mobile platform 200 can be located in the third box outside area A3. In this way, different test objects can be tested simultaneously or with overlapping time, thereby saving test time.
