Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, specifically relating to a durability testing device for automotive seat slide rails. Background Art

[0002] A car seat is the seat you sit on when you're in a car. Car seats are installed inside the car via seat rails. The position of the car seat is adjusted using the seat rails, and the seat rails also support the weight of the seat and the passenger. If the quality of the car seat rails is substandard, it will directly affect the quality of the car, and in serious cases, it may endanger the personal safety of the passengers. Therefore, the quality of car seat rails is very important.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please refer to the accompanying diagrams for all instruction manuals:

[0027] A durability testing device for car seat slide rails includes a workbench 1 and a car seat 2. The workbench 1 is provided with a seat fixing mechanism corresponding to the car seat 2. A barrier 3 is fixedly installed on the workbench 1, and a top plate 4 is fixedly installed on the barrier 3. The barrier 3 and the top plate 4 are provided with a simulation slide rail durability testing component corresponding to the car seat 2.

[0028] The simulation slide rail durability testing component includes a groove 5 located on the enclosure 3. A reciprocating screw 6 is rotatably connected within the groove 5. A moving block 7 is threadedly connected to the reciprocating screw 6. A telescopic rod 8 is rotatably connected to the moving block 7. The movable end of the telescopic rod 8 is threadedly connected to the inner rail of the car seat 2. The movable end of the telescopic rod 8 has a threaded hole, through which it is threadedly connected to the inner slide rail. A motor 9 is fixedly installed on the enclosure 3. The output end of the motor 9 is fixedly connected to the reciprocating screw 6. 4. Slide rods 10 are symmetrically fixedly installed on the upper part. Slider 11 is slidably connected between slide rods 10. Electric hydraulic rods 12 are fixedly installed on sliders 11. Connecting rods 13 are symmetrically fixedly installed on the movable end of electric hydraulic rods 12. Pressing plates 14 are hinged between connecting rods 13. Airbags 15 are symmetrically fixedly installed on the lower side of pressing plates 14. Worm gears 16 are fixedly installed on pressing plates 14. Worm gears 17 are rotatably connected to the movable end of electric hydraulic rods 12. Worm gears 16 and worm gears 17 mesh with each other.

[0029] The outer track is usually fixed to the bottom frame of the car seat 1 or the chassis of the car body, while the inner track is directly connected to the car seat 1. The car seat 1 is installed on the inner track by a fixing device.

[0030] As described above, after the car seat 2 is fixed, the telescopic rod 8 is threadedly connected to the inner rail of the car seat 2. After the connection is complete, the electric hydraulic rod 12 is moved to the top of the car seat 1 and then lowered, causing the pressing plate 14 to descend. The pressing plate 14 can be kept horizontal so that the two airbags 15 apply equal pressure to the car seat 1. Then, the motor 9 is controlled to work, driving the reciprocating screw 6 to rotate, and the durability of the slide rail of the car seat 2 can be tested. Alternatively, the worm gear 17 can be rotated to drive the worm wheel 16 to rotate, causing the pressing plate 14 to tilt, so that the airbags 15 on both sides have different pressing surfaces on the car seat 1, simulating the state of a person sitting sideways. This allows for a more accurate test of the slide rail durability.

[0031] As a technical optimization of this utility model, the seat fixing mechanism includes a boss 18 located on the workbench 1, a motor 19 fixedly installed on one side of the boss 18, a groove 20 provided on the boss 18, a double threaded screw 21 rotatably connected in the groove 20, the double threaded screw 21 being fixedly connected to the output end of the motor 19, and a clamping plate 22 symmetrically threadedly connected on the double threaded screw 21, and anti-slip teeth 23 provided on the clamping plate 22;

[0032] As can be seen from the above description, when the car seat 1 is placed on the boss 18, the control motor 19 works, driving the double threaded screw 21 to rotate, which in turn drives the clamping plates 22 on both sides to move in the same direction, so that the clamping plates 22 hold the outer track of the car seat 1, and the inner track above can move normally.

[0033] As a technical optimization of this utility model, a number of pulleys 24 are symmetrically and uniformly rotatably connected on the boss 18.

[0034] As can be seen from the above description, after the car seat 1 is placed on the boss, the pulley 24 can easily move the car seat 2 through the clamps 22 on both sides, so as to achieve quick fixation.

[0035] As a technical optimization of this utility model, the boss 18 is symmetrically provided with a sliding groove 25 corresponding to the groove 20, and the clamping plate 22 is slidably connected to the sliding groove 25.

[0036] As can be seen from the above description, the design of the slide groove 25 can improve the stability of the clamping plate 22 when it moves.

[0037] As a technical optimization of this utility model, the movable block 7 is slidably connected to the inner wall of the groove 5;

[0038] As can be seen from the above description, this connection method enables the moving block 7 to have better stability when moving.

[0039] As a technical optimization of this utility model, the enclosure 3 is symmetrically and fixedly connected with support rods 26 corresponding to the top plate 4;

[0040] As can be seen from the above description, the support rod 26 can increase the stability of the top plate 4 and extend its overall service life.

[0041] As a technical optimization of this utility model, an adjustment knob 27 is fixedly installed on the worm gear 17;

[0042] As can be seen from the above description, the rotation of the worm gear 17 can be easily controlled by adjusting the knob 27.

[0043] The working process of this utility model is as follows:

[0044] First, place the car seat 1 on the boss 18, control the motor 2 19 to work, drive the double threaded screw 21 to rotate, drive the clamping plates 22 on both sides to move in the same direction, and with the function of the pulley 24, the clamping plates 22 clamp the outer track of the car seat 1, and the inner track above can move normally.

[0045] After the car seat 2 is fixed in place, the telescopic rod 8 is threadedly connected to the inner rail of the car seat 2. After the connection is made, the electric hydraulic rod 12 is moved to the top of the car seat 1 and then lowered, causing the pressing plate 14 to descend. The pressing plate 14 can be kept horizontal first, so that the two airbags 15 apply equal pressure to the car seat 1. Then, the motor 9 is controlled to work, driving the reciprocating screw 6 to rotate, and the durability of the slide rail of the car seat 2 is tested. Alternatively, the worm gear 17 can be rotated to drive the worm wheel 16 to rotate, causing the pressing plate 14 to tilt, so that the airbags 15 on both sides have different pressing surfaces on the car seat 1, simulating the state when a person is sitting sideways. This allows for a more accurate test of the slide rail durability.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
