Description

Technical Field

[0001] This utility model belongs to the field of automotive collision technology, specifically relating to an automotive seat collision test device. Background Technology

[0002] Car seats are an extremely important tool for drivers in a car. Their comfort, safety, and durability in various situations are of utmost importance. Therefore, it is essential to conduct performance tests on car seats after they are manufactured. The seats must also be tested to ensure their stability after a collision.

[0003] Chinese Patent Application No. 2016209297766 discloses a test fixture for securing and limiting the backrest of a car rear seat. The fixture includes a test platform, a backrest frame fixing component for mounting the seat back, and a traction support. A pressure plate is provided on the test platform, and the backrest frame fixing component and the traction support are mounted on the test platform via the pressure plate. The backrest frame fixing component has several positioning blocks for mounting the seat back, and each positioning block has several threaded holes corresponding to mounting holes. A pulley is mounted on the traction support, and a pull rope passes through the pulley. One end of the pull rope has a counterweight, and the other end of the pull rope has a connector for connecting to the seat back.

[0004] The above method allows the seat back to be fixed to a desired position on the test bench using a backrest frame fastener, ensuring a uniform fixing location and facilitating stability testing. However, this method tests seat stability by pulling a rope, which cannot simulate the real-world situation of emergency braking after a car collision, thus compromising the accuracy of the experiment. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a car seat collision testing device, comprising a slide rail bracket, a seat mounting plate, a power mechanism, and a braking mechanism. The slide rail bracket includes a first slide rail and a second slide rail arranged in parallel. The bottom of the seat mounting plate has a first sliding plate and a second sliding plate on both sides. The first sliding plate is slidably connected to the first slide rail, and the second sliding plate is slidably connected to the second slide rail. A car seat is mounted on the top of the seat mounting plate. The power mechanism includes a power motor located at the front end of the slide rail bracket. The output end of the power motor is connected to a connecting block. Fixed plates are connected to both sides of the connecting block. The fixed plates extend downwards from the seat mounting plate, and the top of the fixed plates is connected to the bottom of the seat mounting plate. A brake plate is located in the middle of the bottom of the seat mounting plate. The braking mechanism is located in the middle of the slide rail bracket. The brake plate passes through the braking mechanism, and the braking mechanism drives the brake plate to brake.

[0006] Preferably, the braking mechanism includes a first bracket and a second bracket. The top of the first bracket is provided with a first mounting block, which is connected to a first brake motor. The output end of the first brake motor is connected to a first brake block. The top of the second bracket is provided with a second mounting block, which is connected to a second brake motor. The output end of the second brake motor is connected to a second brake block. The brake plate is located between the first brake block and the second brake block.

[0007] Preferably, the tail end of the slide rail bracket is provided with a shock-absorbing device, the shock-absorbing device includes a shock-absorbing seat, one end of the shock-absorbing seat is connected to a first telescopic rod and a second telescopic rod, and shock-absorbing springs are sleeved on the outside of the first telescopic rod and the second telescopic rod.

[0008] Preferably, the brake plate is provided with several heat dissipation holes.

[0009] Preferably, rubber blocks are installed on the opposing surfaces of the first and second brake blocks.

[0010] The advantages of this utility model are:

[0011] 1. This design uses a motor to drive the seat mounting plate at high speed, which more realistically simulates the dynamic characteristics of a car during driving. This simulation method not only considers changes in speed but also implicitly includes the effects of acceleration and deceleration on the seat, making the experimental results closer to the seat response under real collision conditions.

[0012] 2. This solution also includes a shock absorption device. When the seat mounting plate is impacted, the shock absorption device can effectively reduce the impact force through the buffering effect of the shock absorption spring, thereby protecting the experimental device from damage, extending the service life of the experimental device, and avoiding experimental interruption or failure due to device damage.

[0013] 3. The brake plate in this design has heat dissipation holes, and the brake block has rubber blocks. The design of the heat dissipation holes and rubber blocks can reduce heat attenuation and vibration interference during braking, making the experimental data more accurate and reliable, and helping researchers to more accurately evaluate the braking response of the seat after a collision.

In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1, such as Figure 1-4As shown, a car seat collision test device includes a slide rail bracket 1, a seat mounting plate 2, a power mechanism, and a braking mechanism. The slide rail bracket 1 includes a first slide rail 3 and a second slide rail 4 arranged in parallel, with supports at the bottom of both the first slide rail 3 and the second slide rail 4. The bottom of the seat mounting plate 2 has a first sliding plate 5 and a second sliding plate 6 on both sides. The side of the first sliding plate 5 has a strip-shaped protrusion that matches the transverse groove on the first slide rail 3, and the first sliding plate 5 is slidably connected to the first slide rail 3. The side of the second sliding plate 6 also has a strip-shaped protrusion that matches the transverse groove on the second slide rail 4, and the second sliding plate 6 is slidably connected to the second slide rail 4. The seat mounting plate 2 can slide on the slide rail bracket 1 via the first sliding plate 5 and the second sliding plate 6.

[0023] Combination Figure 1 A car seat 7 is mounted on top of the seat mounting plate 2. The power mechanism includes a motor 8 located at the front end of the slide rail bracket 1. The output end of the motor 8 is connected to a connecting block 9, and fixing plates 10 are connected to both sides of the connecting block 9. The fixing plates 10 extend downwards from the seat mounting plate 2, and their tops are connected to the bottom of the seat mounting plate 2. The motor 8 drives the seat mounting plate 2 to move at high speed through the connecting block 9 and the fixing plates 10, simulating the driving process of a car. Driving the seat mounting plate 2 to move at high speed by the motor 8 can more realistically simulate the dynamic characteristics of a car during driving. This simulation method not only considers changes in speed but also implicitly includes the effects of acceleration and deceleration on the seat, making the experimental results closer to the seat response under real collision conditions.

[0024] Combination Figure 2 A brake plate 11 is located at the bottom center of the seat mounting plate 2. The braking mechanism is located in the middle of the slide rail bracket 1. The brake plate 11 passes through the braking mechanism, and the braking mechanism drives the brake plate 11 to brake. When braking occurs after simulating a car collision, the brake plate 11 is braked urgently by the braking mechanism to test whether the car seat 7 on the seat mounting plate 2 will shift or be damaged after braking.

[0025] Combination Figure 2 and Figure 4The braking mechanism includes a first bracket 12 and a second bracket 13. The bottoms of the first bracket 12 and the second bracket 13 are fixed to the ground. A first mounting block 14 is horizontally arranged on the top of the first bracket 12, and a first brake motor 15 is connected to the first mounting block 14. The output end of the first brake motor 15 is connected to a first brake block 16. A second mounting block 17 is horizontally arranged on the top of the second bracket 13, and a second brake motor 18 is connected to the second mounting block 17. The output end of the second brake motor 18 is connected to a second brake block 19. A brake plate 11 is located between the first brake block 16 and the second brake block 19. Under the action of the first brake motor 15 and the second brake motor 18, the first brake block 16 and the second brake block 19 move towards the center to clamp the brake plate 11, thereby achieving the braking effect. The braking mechanism is located in the middle of the slide rail bracket 1, and can perform emergency braking through the brake plate 11 after simulating high-speed movement of the seat. This braking method can accurately simulate the emergency braking situation of a car after a collision, thereby assessing the firmness and safety of the seat after a collision. Furthermore, the first brake motor 15 and the second brake motor 18 drive the first brake block 16 and the second brake block 19 respectively, achieving double clamping of the brake plate 11. This design not only improves braking stability but also ensures that even if a single brake motor fails, the other brake motor can continue to work, guaranteeing the safe conduct of the experiment.

[0026] Combination Figure 1 The slide rail bracket 1 has a shock-absorbing device at its tail end, which includes a shock-absorbing seat 20. One end of the shock-absorbing seat 20 is connected to a first telescopic rod 21 and a second telescopic rod 22. A shock-absorbing spring 23 is fitted around the first telescopic rod 21 and the second telescopic rod 22. When the first telescopic rod 21 and the second telescopic rod 22 are impacted by the seat mounting plate 2, the shock-absorbing spring 23 reduces the impact of the seat mounting plate 2. During the simulated emergency braking process after a car collision, the seat mounting plate 2, along with the car seat 7, impacts the tail end of the slide rail bracket 1 at a certain speed. Without the shock-absorbing device, this impact would directly affect the slide rail bracket 1 and other parts of the experimental setup, potentially causing structural damage or experimental errors. The shock-absorbing device absorbs and disperses this impact energy, protecting the experimental setup from damage.

[0027] Combination Figure 2The brake plate 11 has several heat dissipation holes, and rubber blocks 24 are installed on the opposing surfaces of the first brake block 16 and the second brake block 19. The heat dissipation holes allow air to flow more effectively across the brake plate 11, increasing the heat exchange area and thus improving the heat dissipation efficiency of the brake plate 11. This helps reduce heat accumulation during braking, prevents overheating, and extends the service life of the brake plate 11. The rubber blocks 24 have a high coefficient of friction, increasing the friction between the first and second brake blocks 16 and the brake plate 11, ensuring the reliability and stability of braking. The combined design of the heat dissipation holes and rubber blocks 24 simultaneously improves heat dissipation efficiency and braking friction, thereby enhancing braking performance. The design of the heat dissipation holes and rubber blocks 24 reduces thermal decay and vibration interference during braking, making experimental data more accurate and reliable, and helping researchers to more accurately evaluate the seat's braking response after a collision.
