Description

Technical Field

[0001] This utility model relates to the field of automotive seats, and in particular to a measuring auxiliary device for measuring the anti-submersion performance of a seat. Background Technology

[0002] Seat anti-submersion performance is a core safety performance indicator that measures how well a car seat (especially the front seat) can prevent occupants from sliding forward and downward due to inertia (i.e., "submerging") in scenarios such as emergency braking, rapid deceleration, or frontal collisions. It is directly related to the effectiveness of seat belt protection and the collision safety of occupants.

[0003] Currently, the anti-submarine performance of car seats can only be evaluated through dynamic crash tests, which are very costly. There is an urgent need for a mature and applicable static testing method and its measurement auxiliary device. Utility Model Content

The main frame is fixed on a test bench, the inclined support platform is fixed to the bottom of the main frame, a set of seat fixing clamps is fixed on the support platform, the limiting device consists of a set of guide slide rods, the set of guide slide rods is vertically fixed to the main frame and symmetrically arranged, the top of the guide slide rods abuts against the top of the main frame, the bottom of the guide slide rods abuts against the bottom of the main frame, the equipment connecting seat is slidably connected to the set of guide slide rods, and the loaded dummy buttock is mounted on the equipment connecting seat.

[0006] As a preferred embodiment of this utility model, a set of guide slide rods consists of two guide slide rods, which pass through the bearing platform and are fixed to the main frame.

[0007] As a preferred embodiment of this utility model, a set of seat fixing clamps consists of four clamp seats. The bottoms of the four clamp seats are rectangularly distributed and fixed to the support platform. The tops of the clamp seats are fixed to the test seat, and the bottoms of the clamp seats are fixed to the support platform by bolts.

[0008] As a preferred embodiment of this invention, the loading dummy and the equipment connecting seat are slid on the guide slide rod by an electric lever / hydraulic cylinder.

[0009] As a preferred embodiment of this invention, a force sensor and a displacement sensor are installed on the electric lever / hydraulic cylinder to detect the applied force and position.

[0010] As a preferred embodiment of this utility model, the electric lever / hydraulic cylinder has a force range of 20kN to 50kN and a displacement range greater than 500mm.

[0011] The beneficial effects of this utility model are as follows: by using special equipment to test the anti-submersion performance of the seat, the accuracy of the test is ensured, while the testing cost is also reduced. Attached Figure Description

[0017] See Figure 1-3 As shown in the figure, this embodiment provides a measurement auxiliary device for measuring the anti-submersion performance of a seat, including: a main frame 1, a support platform 2, a seat fixing clamp 3, a limiting device, a loading dummy buttock 4, and an equipment connecting seat 5. The main frame 1 is fixed on the test bench at the test position. The inclined support platform 2 is fixed to the bottom of the main frame 1, and the bottom position of the inclined direction is located on one side of the loading dummy buttock 4. A set of four seat fixing clamps 3 are fixed on the support platform 2. The limiting device consists of a set of two guide slide rods 6. The two guide slide rods 6 are vertically fixed to the main frame 1 and symmetrically arranged. The top of the two guide slide rods 6 abuts the top of the main frame 1, and the bottom of the two guide slide rods 6 abuts the bottom of the main frame 1. The two guide slide rods 6 pass through the support platform 2 and are fixed to the main frame 1. The equipment connecting seat 5 is slidably connected to the two guide slide rods 6, and the loading dummy buttock 4 is installed on the equipment connecting seat 5.

[0018] In this embodiment, an electric lever / hydraulic cylinder drives the loading dummy 4 and the equipment connecting seat 5 to slide on the guide slide rod 6. Force and displacement sensors are installed on the electric lever / hydraulic cylinder to detect the loading force and position. The electric lever / hydraulic cylinder has a force range of 20kN to 50kN and a displacement range greater than 500mm.

[0019] The workflow includes the following steps:

[0020] Step S1: Prepare the sample to be tested, which is a complete seat with skin and foam;

[0021] Step S2: Fix the seat to the support platform and adjust the seat position. Measure the highest point of the seat slide rail, other designated positions, and the lowest point of the slide rail. The loading speed for the artificial buttocks is 60-200 mm / min.

[0022] Step S3: The electric lever / hydraulic cylinder drives the loading prosthetic buttock 4 to load the seat basin. During loading, the pelvic angle of the loading prosthetic buttock 4 is 25°, the Y-axis center of the loading prosthetic buttock 4 is aligned with the Y-axis center of the seat, and the H-point of the loading prosthetic buttock 4 in the X-axis direction is aligned with the anti-submersion crossbeam. The loading direction is vertically downward. The loading prosthetic buttock uses an SAE J826 dummy prosthetic buttock.

[0023] Step S4: Result evaluation includes the following two methods:

[0024] Method 1: When the force sensor detects that the target force value has been reached, the displacement sensor detects the loaded displacement to determine whether the set threshold requirement has been reached.

[0025] Method 2: When the displacement sensor detects that the set displacement has been applied, the force sensor detects whether the force value meets the set threshold requirement.

[0026] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
