Description

Technical Field

[0001] The utility model relates to the field of automobile collision test equipment, in particular to an automobile seat installation tool. Background Art

[0002] With the rapid development of the automobile industry, people are paying more and more attention to the safety of car seats. As an important safety device inside the car, car seats play a vital role in the safety of passengers. In order to ensure the safety performance of car seats, the automobile industry has formulated a series of specifications, regulations and standards to conduct safety tests on seats.

[0003] In automobile safety testing, a trolley collision test is generally required to verify the seat's ability to absorb and disperse impact force, as well as the deployment time and force of the built-in airbag, to ensure its normal operation. At present, in the trolley collision test, the car seat is installed on the slide through the seat tooling. Usually, the general seat tooling is fixed and cannot be moved or rotated. The relative spatial position between the seat and the door interior cannot be guaranteed, which makes the test results have large errors, especially the test of the deployment time and deployment force of the airbag. The spatial distance between the door interior and the car seat is high, and it is often necessary to conduct a real car collision test to obtain accurate test results, so as to improve the airbag to protect the safety of passengers, resulting in high test costs. Utility Model Content

[0004] The utility model aims to provide a vehicle seat installation tool, so as to obtain relatively accurate test data through simulation test, thereby reducing the number of real vehicle collision tests and reducing the test cost.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a car seat installation tool, including a test bench, a chassis, a slide and a tool body, the chassis is rotatably fixed on the test bench, the chassis is provided with a mounting unit, the mounting unit includes at least two groups of positioning parts, each group of positioning parts includes at least two threaded holes, the connecting line of the threaded holes in one group of positioning parts is parallel to the axis of the test bench, and the connecting line of the threaded holes in the other group of positioning parts forms an angle of 15° with the axis of the test bench, the slide is slidably arranged on the chassis, and the tool body is rotatably fixed on the slide.

[0006] The beneficial effects of this solution are: 1. The slide is set on the chassis, and two sets of positioning parts are set on the chassis, so that the chassis can be used for frontal collision and surface collision at the same time, achieving the technical effect of one object for multiple uses, thereby reducing the number of test equipment, further reducing the test cost, and reducing R&D investment; 2. The tooling body is rotatably set on the slide. During installation, the distance between the seat and the door interior can be adjusted by rotating the angle of the tooling body. The distance between the seat and the door interior can be infinitely adjusted to ensure that the spatial distance between the seat and the interior is consistent with the spatial position of the actual vehicle design, so that the pop-up process of the built-in airbag in the seat is closer to the pop-up state during actual use, so that when the seat is subjected to a collision test to verify the seat's ability to absorb and disperse impact force, the deployment force and deployment time of the built-in airbag of the seat are tested simultaneously, thereby reducing the test cost and obtaining accurate results, so as to better optimize and improve the seat and the built-in airbag of the seat, and reduce the R&D cycle and R&D cost.

[0007] Furthermore, a long hole is provided on the tool body, and a mounting hole is provided on the slide. When the tool body rotates on the slide, the long hole is connected with the mounting hole.

[0008] Beneficial effect: The long holes and the mounting holes ensure that the tool body can rotate on the slide. It only needs to ensure that the width of the long holes is greater than the diameter of the mounting holes. After the position of the slide is determined, the tool can be fine-tuned in the width and length directions of the long holes on the slide. It only needs to ensure that the long holes are connected with the mounting holes when the slide rotates, so that the tool body can be infinitely adjusted. The structure is simple and the cost is low.

[0009] Furthermore, a guide rail is fixed on the chassis, a slider is fixed on the bottom of the slide, and the slider is adapted to the slide rail.

[0010] Beneficial effect: Through the cooperation of the guide rail and the slider, the slide can slide freely on the chassis, and the test personnel can easily adjust the relative position of the slide to make the slide located at the best location for the test, thereby reducing the difficulty of the test.

[0011] Furthermore, stoppers are fixedly provided at both ends of the slide rail.

[0012] Beneficial effect: By setting blocks at both ends of the slide rail, it can effectively prevent the limit between the slide and the chassis from falling off during the impact test, or because the test personnel are careless and fail to fix the slide after adjusting the position of the slide, resulting in the slide sliding during the impact, causing the slider to separate from the slide rail, resulting in the loss of parts and difficulty in finding them, or causing damage to other instruments and equipment, increasing the test cost; in addition, when the seat to be tested is installed on the tooling, the overall weight of the slide, tooling and seat is large. When the chassis is not in a horizontal state, that is, when the chassis is an inclined plane, the test personnel may negligently cause the slide to slide when adjusting the position of the seat, causing the slider to separate from the guide rail. The test personnel cannot reinstall the slider on the guide rail well, and need to remove the seat fixed on the tooling, reinstall the slider on the guide rail, and then install the seat, which seriously slows down the test efficiency.

[0013] Furthermore, a positioning bar is provided on the chassis, a plurality of first positioning holes are provided on the positioning bar, a second positioning hole is provided on the slide, and a positioning pin is provided between the first positioning hole and the second positioning hole.

[0014] Beneficial effects: 1. The design of the positioning strip, positioning hole and positioning pin can effectively prevent the slide from sliding on its own, so that the slide is in the position preset by the tester; 2. It is also convenient to confirm the position of the slide, so as to repeat the test and ensure the accuracy of the experimental results.

[0015] Furthermore, the positioning pin is T-shaped and includes an inserting portion and a clamping portion, the inserting portion is adapted to the first positioning hole, and the clamping portion is adapted to the second positioning hole.

[0016] Beneficial effects: The insertion part is precisely matched with the first positioning hole on the slide or chassis, and can penetrate into the hole to achieve preliminary positioning and fixing, ensuring the stability of the relative position between the two, while the clamping part is adapted to the second positioning hole. When the positioning pin is fully assembled in place, the clamping part will form a blockage in the second positioning hole, thereby achieving a double locking effect, further enhancing the stability of the overall structure, and effectively preventing accidental sliding or position displacement after the slide is adjusted into place under external vibration, impact and other conditions, thereby achieving the fixation of the slide and the chassis, and avoiding sliding again after the slide is adjusted to a certain position.

[0017] Furthermore, the clamping portion is hinged with a lifting ring.

[0018] Beneficial effects: 1. Through the design of the lifting ring, the operator can easily hook the lifting ring with his fingers, so as to conveniently remove or insert the locating pin from the first locating hole and the second locating hole without using additional tools, thereby improving the convenience of operation and greatly improving work efficiency; 2. Due to the presence of the lifting ring, the force and direction can be better controlled during the disassembly and assembly process, preventing component damage or personal injury caused by improper force, and improving the safety of operation.

[0019] Furthermore, a gasket is provided between the bolt and the elongated hole, and the diameter of the gasket is greater than the width of the elongated hole.

[0020] Beneficial effects: 1. The contact area between the bolt and the length adjustment hole is increased, making the bolt's fixation to the seat tooling more stable; 2. Through the design of the gasket, the pressure on the contact surface can be dispersed when the bolt is tightened, avoiding contact surface damage or thread damage caused by local overload, and also protecting the surface of the connected parts from direct extrusion and damage.

[0029] The embodiment is basically as shown in the attached Figure 1-5 As shown, Figure 1-5 A vehicle seat installation tool as shown in FIG. 1 includes a test bench, a chassis 1, a slide 2, a positioning pin and a seat tool 3, as shown in FIG. Figure 3 , Figure 4As shown, the chassis 1 is provided with a guide rail 221, a positioning bar 13 and a stopper 223, a slider 222 is slidably provided on the guide rail 221, and the stopper 223 is fixed to the chassis 1 at both ends of the guide rail 221 by bolts, so as to prevent the slider 222 from being separated from the guide rail 221, and the guide rail 221 and the positioning bar 13 are fixedly connected to the chassis 1 by bolts, and a plurality of first positioning holes 131 are equidistantly provided on the positioning bar 13, and an installation unit is provided on the chassis 1, and the installation unit includes two sets of positioning parts and corresponding bolts, such as Figure 4 As shown, the two groups of positioning parts are respectively the front collision mounting hole 11 and the side collision mounting hole 12. The front collision mounting hole 11 and the side collision mounting hole 12 each include two threaded holes. The connecting line of the threaded holes of the front collision mounting hole 11 is parallel to the axis of the test bench, and the connecting line of the threaded holes of the side collision mounting hole 12 is at an angle of 15° to the axis of the test bench. When in use, according to the collision situation, the chassis 1 is installed on the test bench through the front collision mounting hole 11 or the side collision mounting hole 12, and the corresponding door interior is installed.

[0030] The slide 2 is fixed to the slider 222 by bolts. Figure 3 As shown, a second positioning hole 21 and a mounting hole 22 are provided on the slide 2. The second positioning hole 21 is adapted to the first positioning hole 131. The mounting hole 22 is used to install the seat tooling 3, so that the seat tooling 3 can be adjusted in the horizontal and vertical directions, and after the slide 2 is adjusted to the corresponding position, the position of the slide 2 can be accurately recorded, thereby achieving the repeatability of the test. During the test, the slide 2 can be fixed to the chassis 1 by the positioning pin to avoid sliding of the slide 2 during the test, which makes the test data inaccurate.

[0032] like Figure 1 , Figure 2 The seat tooling 3 shown is provided with a long hole 31, a bolt is provided in the long hole 31, the mounting hole 22 is provided with an internal thread, the bolt is adapted to the mounting hole 22, a gasket is provided between the bolt and the tooling, and the width of the long hole 31 is larger than the diameter of the mounting hole 22, so that the seat tooling 3 can fine-tune the position of the seat tooling 3 through the long hole 31, so that the distance between the seat and the door interior is consistent with the actual vehicle, reducing the test error, and the diameter of the gasket is larger than the width of the long hole 31, thereby increasing the contact area between the bolt and the long hole 31, thereby enhancing the stability of the fixation between the seat tooling 3 and the slide 2.

[0033] The specific implementation process is as follows:

[0034] When in use, first, according to the test situation, select the front collision mounting hole 11 or the side collision mounting hole 12, install the chassis 1 on the test bench by bolts, and install the door interior to simulate the actual use scenario of the seat as much as possible; secondly, fix the slide 2 on the slider 222, and adjust the position of the slide 2 to determine the longitudinal position; thirdly, install the seat tooling 3 on the slide 2, and install gaskets and bolts to roughly determine the lateral position of the seat tooling 3, and fix the seat on the seat tooling 3. It should be noted that the bolts in the long holes 31 cannot be tightened; finally, adjust the position of the seat tooling 3 again through the long holes 31, thereby adjusting the distance between the seat and the door interior, so that the distance between the seat and the door interior is consistent with the actual vehicle, tighten the bolts in the long holes 31, and fix the seat tooling 3 on the slide 2, so as to test the seat's ability to absorb and disperse impact force during collision, as well as the deployment force and deployment time of the seat's built-in airbag, and then obtain as complete test data as possible through as few tests as possible to reduce the R&D cycle and R&D cost.
