[0019] The utility model is further described below in conjunction with the accompanying drawings.
[0020] like Figure 1 The utility model is an auxiliary tooling for a trolley test of luggage displacement passenger protection device test, comprising a frame 1, a material bearing seat 2, an electric screw 3, a guide rail 4, a first slider 5 and a second slider 6. The electric screw 3 and the guide rail 4 are vertically arranged on the frame 1, the first slider 5 and the second slider 6 are slidably connected to the guide rail 4, and elastic buffer portions are provided on the second slider 6 and the nut 31 of the electric screw 3. The two material bearing seats 2 are arranged in upper and lower layers, the upper material bearing seat 2 is fixedly connected to the first slider 5, and the lower material bearing seat 2 is fixedly connected to the second slider 6 and the elastic buffer portion on the nut.
[0021] When in use, the tooling of the utility model is fixed on the test trolley together with the car seat tooling, and then the height of the two material bearing seats 2 is adjusted according to the size of the car seat, wherein the height of the lower material bearing seat 2 is adjusted by an electric screw, and the height of the upper material bearing seat 2 is adjusted manually. After adjusting to the appropriate height, mass blocks are placed on the two material bearing seats 2 respectively, and the mass block on the upper material bearing seat 2 is aligned with the headrest of the seat, and the mass block on the lower material bearing seat 2 is aligned with the backrest of the seat. Then a simulated collision test is carried out. The process of the simulated collision test is that the trolley moves at high speed and then suddenly stops. Due to inertia, the mass blocks on the two material bearing seats 2 fly out and hit the headrest and the backrest, thereby carrying out a collision test.
[0022] The upper material holder 2 is fixed by passing bolts through the corresponding first slider 5, and the bolts are tightened to abut against the guide rail. Since most of the headrests are not subjected to collision tests, the upper material holder can be directly removed when the headrest is not tested. Therefore, the upper material holder is made into a manual structure in the utility model, which is convenient for loading and unloading.
[0023] In order to make the mass block fly out from the material holder 2 better, the side of the material holder 2 facing the seat is an open structure, specifically: the material holder 2 is a rectangular seat with a rectangular bottom and three side edges, and the opening of the material holder 2 faces the seat. Waist-shaped holes are provided on the mutually parallel side edges of the material holder 2, and bolts pass through the waist-shaped holes and are fixedly connected to the first slider 5 or the elastic buffer portion. The purpose of providing the waist-shaped holes on the material holder 2 is to adjust the installation angle of the material holder 2.
[0024] like Figure 2 and Figure 3 , the structure of the elastic buffer part on the second slider 6 and the nut is as follows: a buffer seat 7 is provided on the outer side of the nut 31 and the second slider 6, a rectangular cavity is provided on the buffer seat 7, the nut 31 and the second slider 6 are placed in the rectangular cavity corresponding to the buffer seat 7, sliding ribs are provided on the outer walls of the nut 31 and the second slider 6, and a sliding groove adapted to the sliding ribs is provided on the cavity wall of the buffer seat 7. The nut 31 and the second slider 6 slide on the buffer seat 7 toward the movement direction of the trolley. A spring 8 is provided between the nut 31 and the buffer seat 7, and between the second slider 6 and the buffer seat 7, and the spring is arranged along the sliding direction of the buffer seat 7, and the buffer seat 7 forms the elastic buffer part.
[0025] The purpose of setting the elastic buffer is that after the trolley stops moving, the moment the mass block flies out, the tooling will shake, causing the material receiving seat 2 to react on the lead screw. Since the lead screw is a high-precision component, the buffer can effectively reduce the force reacting on the lead screw, thereby extending the service life of the tooling.
[0026] The utility model has two electric screws 3 and four guide rails 4, and a guide rail 4 is arranged on the front and rear sides of each electric screw 3. The electric screw 3 is arranged in the middle, and the two guide rails bear the brunt of the vibration, which can better protect the electric screw.
[0027] In order to increase the use area of the material receiving seat 2, an extension plate 21 is provided on the material receiving seat. The extension plate 21 is hinged on the material receiving seat. When the large-volume mass block is not needed, the extension plate is folded up, and when needed, the extension plate is unfolded.
[0028] like Figure 4 A plurality of first hinged ears 22 are provided on the bottom surface of the material receiving seat 2, and a plurality of second hinged ears 23 are provided on the extension plate 21. The first hinged ears 22 and the second hinged ears 23 are both inclined downward, and a fixing rod 24 is passed through the first hinged ears 22 and the second hinged ears 23. The two ends of the fixing rod 24 are threadedly connected with locking nuts. When the extension plate 21 is unfolded, the locking nut is loosened, and then the extension plate is laid flat, and finally the locking nut is tightened.
[0029] After the extension plate is placed horizontally (the upper surface is flush with the upper surface of the bottom plate of the material receiving seat 2), in order to further ensure the support stability of the extension plate, a support block 25 is rotatably connected to the bottom surface of the material receiving seat 2. After the extension plate 21 is in a horizontal state, the support block 25 is rotated so that the two sides of the support block 25 are respectively placed under the material receiving seat 2 and the extension plate 21. The support block 25 is supported at the junction of the material receiving seat 2 and the extension plate 21 to ensure the support stability of the extension plate.
[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
