Description

Technical Field

[0001] The utility model relates to the technical field of air bag detection devices, in particular to a waist support air bag durability testing tool. Background Art

[0002] With the development of the automobile industry, in order to make passengers more comfortable when riding, existing cars are generally equipped with car seat lumbar support devices, which can effectively provide good support for the passenger's waist and relieve waist fatigue and discomfort caused by sitting for a long time.

[0003] A waist support air bag inflation test device mentioned in an existing Chinese public patent (authorization announcement number: CN219573479U) can facilitate the placement of a pressure block through a placement groove to prevent the pressure block from sliding on the guide block. The same group has no less than two feeding cylinders, which increases the stability of the overall structure. Through a number of counterweights of different masses, the mass of the pressure block can be adjusted according to actual testing needs to meet the needs of different conditions. The sensor is movable and can be used to detect the height of the air bag to determine whether the air bag meets the requirements.

[0004] In the existing method of testing the waist support air bag, the waist support air bag is first placed in the placement slot, and then the weight of the pressure block is adjusted by the counterweight block, and then the waist support air bag is inflated to complete the testing of the waist support air bag. However, after the counterweight block is placed, the air bag gradually expands and squeezes the pressure block, which may cause the counterweight block above the pressure block to shift and fall, requiring the staff to pick up the counterweight block and replace it, which is relatively inconvenient. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the counterweight block above the pressure block may be displaced and fall off, and the utility model provides a waist support air bag durability test tool.

[0008] By adopting the above technical solution, the waist support air bag is placed on the frame, and then the counterweight is placed on the load-bearing platform as needed. Then, by inflating the waist support air bag, the air bag will come into contact with the load-bearing platform when inflated, causing the load-bearing platform to move on the test frame. The air in the waist support air bag is then extracted, and the waist support air bag test is completed by repeating the above process. The clamping mechanism can reduce the risk of the counterweight being displaced and falling, and the protective mechanism can reduce the risk of the waist support air bag rupturing and affecting the staff.

[0010] By adopting the above technical solution, the knob is first turned to drive the clamping block to clamp the counterweight block, so that the counterweight block is fixed above the load-bearing platform, reducing the risk of the counterweight block being displaced and falling.

[0011] Furthermore, a guide rod is fixedly connected to a surface of the clamping block close to the threaded rod, an end of the guide rod away from the clamping block passes through the fixed block, and the fixed block is slidably connected to the guide rod.

[0012] By adopting the above technical solution, the guide rod provides a guiding function for the clamping block, so that the clamping block can remain stable during movement.

When the protective plate moves to the placement seat, the protective plate blocks the placement frame, reducing the risk of the waist support air bag exploding during testing and affecting the staff.

[0015] Furthermore, a connecting block is fixedly connected to the outer side of the protective plate, a connecting hole is opened on the outer side of the connecting block, a plurality of fixed frames are fixedly connected to the outer side of the detection box, a movable plate is slidably connected to the inner side of the fixed frame, a driving plate is symmetrically fixedly connected to the outer side of the movable plate, the driving plate passes through the fixed frame, the fixed frame is slidably connected to the driving plate, and a handle is fixedly connected between the two driving plates.

[0016] By adopting the above technical solution, the protective plate can be fixed by the fixing frame.

[0017] Furthermore, a spring is fixedly connected to the outer side of the movable plate away from the docking block, and the outer side of the spring away from the movable plate is fixedly connected to the inner side of the fixed frame.

[0018] By adopting the above technical solution, the spring reset can drive the docking block to fix the protective plate.

[0019] In summary, the present invention includes at least one of the following beneficial effects:

[0020] 1.

[0029] The following is combined with Figure 1-5The utility model is described in further detail.

[0030] The embodiment of the utility model discloses a tool for testing the durability of a waist support air bag.

[0031] Reference Figure 1 and Figure 2 The waist support air bag durability test tooling includes a test box 1, a plurality of test frames 2 are fixedly connected to the inside of the test box 1, a waist support air bag is placed on the inside of the test frame 2, a load-bearing platform 3 is slidably connected to the outside of the test frame 2, a load-bearing block is overlapped on the top of the load-bearing platform 3, a vibration device 5 is fixedly connected to the inside of the test box 1, a clamping mechanism is symmetrically arranged on the top of the load-bearing platform 3, and a plurality of protective mechanisms are arranged on the inside of the test box 1.

[0032] When testing the lumbar support air bag, first place the lumbar support air bag on the frame, then place the counterweight 4 on the load-bearing platform 3 according to the situation, and then inflate the lumbar support air bag. When the air bag is inflated, it will contact the load-bearing platform 3, causing the load-bearing platform 3 to move on the testing frame 2. While the lumbar support air bag is inflated, start the vibration device 5 inside the testing box 1. The vibration device 5 will generate vibrations of a certain frequency and amplitude to simulate the vibration environment during the driving of the car. Then the air in the lumbar support air bag is extracted, and the lumbar support air bag test is completed by repeating the above process. The counterweight 4 can be clamped by the clamping mechanism to reduce the risk of the counterweight 4 being displaced and falling. The testing frame 2 can be protected by the protective mechanism to reduce the risk of the lumbar support air bag rupture affecting the staff.

[0033] Reference Figure 2 and Figure 3 The clamping mechanism includes fixed blocks 6 symmetrically fixedly connected to both sides of the top of the load-bearing platform 3, the outer side of the fixed block 6 is threadedly connected to a threaded rod 7, the outer side of the threaded rod 7 is fixedly connected to a knob 8, and the end of the threaded rod 7 away from the knob 8 passes through the fixed block 6 and is rotatably connected to the clamping block 9.

[0034] Among them, the guide rod 10 is fixedly connected to the side of the clamping block 9 close to the threaded rod 7, and the end of the guide rod 10 away from the clamping block 9 passes through the fixed block 6, and the fixed block 6 is slidably connected to the guide rod 10.

[0035] When clamping the counterweight 4, first turn the knob 8 to drive the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the fixed block 6 so that the threaded rod 7 drives the clamping block 9 to clamp the counterweight 4, so that the counterweight 4 is fixed above the load-bearing platform 3. By clamping the counterweight 4, the risk of the counterweight 4 being displaced and falling is effectively reduced, the risk of inaccurate detection results due to changes in the counterweight 4 is reduced, and the situation of detection interruption due to displacement of the counterweight 4 or rupture of the waist support air bag is reduced, so that the detection process can be carried out more smoothly.

[0036] When the clamping block 9 moves, the guide rod 10 provides a guiding function for the clamping block 9, so that the clamping block 9 can remain stable during the movement.

[0037] Reference Figure 4 and Figure 5 The protective mechanism includes several sliding seats 11 fixedly connected to the inner side of the detection box 1, the top of the sliding seat 11 is slidably connected to a protective plate 12, the outer side of the protective plate 12 is fixedly connected to a handle 13, and the inner side of the detection box 1 is fixedly connected to several placement seats 14, which are slidably connected to the protective plate 12.

[0038] Among them, the outer side of the protective plate 12 is fixedly connected with a connecting block 15, and a connecting hole 16 is opened on the outer side of the connecting block 15. The outer side of the detection box 1 is fixedly connected with several fixed frames 17, and the inner side of the fixed frame 17 is slidably connected with a movable plate 18. The outer side of the movable plate 18 is symmetrically fixedly connected with a driving plate 20. The driving plate 20 passes through the fixed frame 17, and the fixed frame 17 is slidably connected to the driving plate 20. A handle 21 is fixedly connected between the two driving plates 20.

[0039] In addition, a spring 22 is fixedly connected to the outer side of the movable plate 18 away from the docking block 19 , and the spring 22 is fixedly connected to the inner side of the fixed frame 17 away from the outer side of the movable plate 18 .

[0040] When the lumbar support air bag is being tested, the staff pushes the handle 13 to drive the protective plate 12 to move on the sliding seat 11. When the protective plate 12 moves to the placement seat 14, the protective plate 12 blocks the placement frame, reducing the risk of the lumbar support air bag exploding during testing and affecting the staff's work. At the same time, it can reduce the damage caused by rupture to surrounding equipment and the working environment, thereby reducing maintenance costs and the time required to resume work.

[0041] When the protective plate 12 moves, the staff first pulls the handle 21 to drive the driving plate 20 to move. The movement of the driving plate 20 drives the moving plate 18 to move, and the movement of the moving plate 18 drives the docking block 19 to move. When the moving plate 18 moves, it squeezes the spring 22, causing the spring 22 to generate elastic potential energy. When the docking hole is adapted to the docking block 19, the staff releases the handle 21. At this time, the elastic potential energy of the spring 22 is released, causing the docking block 19 to reset into the docking hole, thereby completing the fixation of the connecting block 15, thereby fixing the protective plate 12 and reducing the risk of displacement of the protective plate 12 during the protection process.

[0042] Working principle: Place the waist support air bag on the frame, and then place the counterweight 4 on the load-bearing platform 3 according to the situation, and then inflate the waist support air bag. When the air bag is inflated, it will contact the load-bearing platform 3, causing the load-bearing platform 3 to move on the detection frame 2, and then the air in the waist support air bag is extracted. The waist support air bag test is completed by repeating the above process, and the knob 8 is turned to drive the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the fixed block 6 so that the threaded rod 7 drives the clamping block 9 to clamp the counterweight 4, so that the counterweight 4 is fixed above the load-bearing platform 3. By clamping the counterweight 4, the risk of the counterweight 4 being displaced and falling is effectively reduced.

[0043] The staff pushes the handle 13 to drive the protective plate 12 to move on the sliding seat 11. When the protective plate 12 moves to the placement seat 14, the protective plate 12 blocks the placement frame to reduce the risk of the waist support airbag exploding during testing and affecting the staff. The elastic potential energy of the spring 22 is released to reset the docking block 19 into the docking hole, thereby completing the fixation of the connecting block 15 and thus fixing the protective plate 12.
