AI Technical Summary
[0004]针对上述中的相关技术,这种设备仅能对安全带进行单一性能检测,完全无法还原坠落瞬间,人体因重力加速度产生的巨大惯性冲击力,以及该冲击力在极短时间内的复杂变化情况,实际坠落过程中,安全带不仅要承受拉力,还会受到扭转、弯折等多种力的综合作用,单一性能检测设备无法模拟这些复杂的受力情况,导致检测结果与实际使用中的安全性能存在较大偏差,难以全面、准确地评估安全带在真实坠落场景下的可靠性和安全性
1.测试架与释放组件配合,带动模拟人升降,模拟人穿戴安全带从而实现安全带升降,从而模拟安全带在实际使用中的受力情况,提高安全带检测结果的准确性;

Abstract
Claims
1. A seat belt detection device comprising a test stand (1), characterized in that: The test frame (1) is provided with a release component at the upper end and a mannequin at the lower end of the release component. The mannequin and the release component are detachably connected. The release component is used to drive the mannequin to rise and fall. The test frame (1) is fixedly provided with a control cabinet (13). The control cabinet (13) is provided with a ring connector (112). The ring connector (112) is provided with a chain (113). The control cabinet (13) is provided with a connecting shaft (111) at the lower end. The connecting shaft (111) is connected to the chain (113). The connecting shaft (111) is provided with a lifting ring (11) at the lower end. The mannequin is wearing a safety belt. The safety belt is hooked to the lifting ring (11). The control box is provided with a positioning component. The positioning component is used to position the connecting shaft (111).
2. The seat belt detection device of claim 1, wherein: The positioning assembly includes two clamping blocks (131) and two electric cylinders (132). The two clamping blocks (131) are located on both sides of the connecting shaft (111). The clamping blocks (131) are slidably connected to the control cabinet (13) in the transverse direction. The electric cylinders (132) correspond one-to-one with the clamping blocks (131). The electric cylinders (132) are located on the side of the clamping blocks (131) away from the connecting shaft (111). The electric cylinders (132) are fixedly connected to the control cabinet (13), and the output end of the electric cylinders (132) is coaxially fixed with the clamping blocks (131).
3. The seat belt detection device of claim 2, wherein: The clamping block (131) has an arc-shaped surface (1311) that fits against the outer wall of the connecting shaft (111).
4. The seat belt detection device of claim 2, wherein: A fixing block (133) is provided between the electric cylinder (132) and the clamping block (131). The fixing block (133) is fixedly connected to the control cabinet (13) and is used to position the clamping block (131).
5. The seat belt detection device of claim 4, wherein: Two guide shafts (134) are provided between the fixing block (133) and the clamping block (131). The two guide shafts (134) are respectively fixed at both ends of the fixing block (133), and the two guide shafts (134) are slidably connected to the clamping block (131) in the transverse direction.
6. The seat belt detection device of claim 4, wherein: A proximity switch (135) is fixed at the upper end of the fixed block (133), and the proximity switch (135) is used to detect the position of the chain (113).
7. The seat belt detection device of claim 1, wherein: The release assembly includes a lifting rope (121) and a second hanging ring (12). The lifting rope (121) is fixed to the upper end of the test frame (1), and the second hanging ring (12) is fixed to the lower end of the lifting rope (121). The second hanging ring (12) is attached to the mannequin.
8. The seat belt detection device of claim 1, wherein: The control cabinet (13) is equipped with two micro switches (138), each corresponding to a clamping block (131). The micro switches (138) are used to detect the position of the clamping block (131).
9. The seat belt detection device of claim 1, wherein: The control cabinet (13) is fixedly equipped with a bracket (136), and a limit switch (137) is provided above the bracket (136). The limit switch (137) is used to detect the extreme position of the ring connector (112).
10. The seat belt detection device of claim 1, wherein: The sensor (114) is arranged between the lifting ring (11) and the connecting shaft (111), and is used to obtain the stress condition of the lifting ring (11). The upper end of the sensor (114) is provided with a inverter (115), and the inverter is used to convert and send the stress data of the sensor (114).
