Description

Technical Field

[0001] This utility model relates to the field of automotive seat testing technology, and in particular to an SBR testing device for automotive seats. Background Technology

[0002] With the rapid development of automotive technologies, driving safety remains paramount. The SBR device is typically installed between the foam and the upholstery or between the foam and the frame of the passenger seat. When a passenger sits down without fastening their seatbelt, the SBR device will issue an alarm to remind the passenger. During the production and processing of car seats, the SBR sensor must be tested by the corresponding SBR testing device before leaving the factory to ensure that the SBR sensor is working properly.

[0003] For example, utility model patent application number 202420552375.8 discloses an SBR testing device for automobile seats, including: a moving mechanism, a pressurizing part, a buffer device, and a contouring device; the contouring device is movably disposed on one side of the moving mechanism and is suitable for being placed on the seat to be tested by the moving mechanism; the pressurizing part is movably disposed on one side of the contouring device, and the pressurizing part and the seat to be tested are located on opposite sides of the contouring device, and the moving direction of the pressurizing part is towards or away from the contouring device.

[0004] Based on existing technology, most existing SBR testing devices for car seats have a simple structure, making it difficult to adjust the position. This makes it difficult for the pressure device to apply pressure to different positions of the car seat, resulting in inconvenience in use. Furthermore, it requires waiting for the previous set of car seats to be tested and removed before the next set of car seats can be tested, which is not conducive to continuous testing and thus reduces testing efficiency to a certain extent. Therefore, this utility model proposes an SBR testing device for car seats to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to propose an SBR testing device for automobile seats, which solves the problems of existing SBR testing devices for automobile seats being inconvenient to adjust in position, making it difficult for the pressure device to apply pressure to different positions of the automobile seat, and being inconvenient to achieve continuous testing, thereby reducing testing efficiency to a certain extent.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: an SBR testing device for automobile seats, including a testing platform, a base that is slidably disposed on the top of the testing platform and driven to move by a traction mechanism, a clamping plate that is symmetrically fixed on the top of the base, an automobile seat body that is clamped and fixed on the top of the clamping plate by a clamping mechanism, a frame that is fixed on the top of the testing platform, a drive box that is driven to move by a longitudinal adjustment mechanism that is disposed on the upper inner side of the frame, a hanging frame that is driven to move by a transverse adjustment mechanism that is disposed at the bottom of the drive box, a pressure block that is connected to the hanging frame by a hydraulic cylinder, an SBR sensor that is disposed inside the automobile seat body, and an indicator light that is electrically connected to the SBR sensor that is fixed on the top of the frame.

[0007] A further improvement is that the traction mechanism includes a take-up machine fixed to both sides inside the detection table and a vertical plate fixed to the bottom of the base. Traction rings are fixed to the outer walls on both sides of the vertical plate, and a traction rope connected to the traction rings is wound around the winding wheel at the output end of the take-up machine.

[0008] A further improvement is that the clamping mechanism includes clamping blocks slidably connected to the four sides of the top of the clamping plate and a fixing block fixed to the side of the clamping blocks away from the car seat body. A locking bolt is threaded through the fixing block, and a locking block is connected to the bottom end of the locking bolt.

[0009] A further improvement is that a T-shaped slider is fixed at the bottom of the clamping block, and a T-shaped groove adapted to the T-shaped slider is opened at the top of the clamping plate, and the T-shaped slider is slidably disposed in the T-shaped groove.

[0010] A further improvement is that the longitudinal adjustment mechanism includes a first lead screw rotatably connected to the inner side of the frame and driven to rotate by a motor, and a longitudinal plate threaded onto the first lead screw. The longitudinal plate is fixed to the top of the drive box, and a limiting rod that slides through the longitudinal plate is symmetrically fixed to the inner side of the frame.

[0011] A further improvement is that the lateral adjustment mechanism includes a second lead screw rotatably connected inside the drive box and rotated by a motor, and a lateral plate threaded onto the first lead screw. The bottom end of the lateral plate slides through the bottom end of the drive box and is fixed to the top of the hanging frame.

[0012] Further improvements include: rollers that rotatably connect to the upper surface of the testing platform on both sides of the bottom end of the base, and sliding rods that slide through the hanging frame are symmetrically fixed at the top of the pressure block.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a testing platform. The drive box is driven to move longitudinally back and forth to an appropriate position through a longitudinal adjustment mechanism, and the hanging frame is driven to move laterally left and right to an appropriate position through a transverse adjustment mechanism. This makes the device easy to adjust and allows the pressure block to be adaptively adjusted to an appropriate position for pressure testing according to actual testing needs. It is convenient to use. Furthermore, by setting a traction mechanism inside the testing platform to drive the base to move laterally left and right at the top of the testing platform, the mounting plates on both sides of the top of the base and the car seat body on the top can be moved alternately to the inside of the frame for SBR testing. This reduces unnecessary loading and unloading waiting time, facilitates continuous testing, and improves testing efficiency to a certain extent. Attached Figure Description

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment provides an SBR testing device for automobile seats, including a hollow testing platform 1 and a base 2 slidably mounted on the top of the testing platform 1. The testing platform 1 has a traction mechanism inside for driving the base 2 to move laterally left and right. The top left and right sides of the base 2 are bolted with clamping plates 3 for placing the automobile seat body 4. The top of the clamping plates 3 has a clamping mechanism for clamping and fixing the automobile seat body 4. A frame 5 is bolted to the middle of the top of the testing platform 1. A drive box 6 is located on the upper inner side of the frame 5, and the drive box 6 is driven by a longitudinal adjustment mechanism inside the frame 5 to move longitudinally back and forth. A hanging frame 7 is slidably mounted on the bottom of the drive box 6, and the hanging frame 7 is driven by a lateral adjustment mechanism inside the drive box 6 to move laterally left and right. A hydraulic cylinder 8 is bolted to the inner side of the hanging frame 7, and the output end of the hydraulic cylinder 8 is located below the hanging frame 7 and bolted with a mechanism for clamping the automobile seat body 4. The pressure block 9, which applies pressure to the seat body 4, is driven by the longitudinal adjustment mechanism to move the drive box 6 longitudinally back and forth to an appropriate position, and by the transverse adjustment mechanism to move the hanging frame 7 laterally to an appropriate position. This makes the device easy to adjust and allows the pressure block 9 to be adaptively adjusted to an appropriate position for pressure testing according to actual testing needs. The car seat body 4 is equipped with an SBR sensor 10 for detecting the pressure on the seat cushion of the car seat body 4. An indicator light 11 is fixed to the top of the frame 5 by bolts. The SBR sensor 10 is connected to the PLC control system of the device and is used to activate the indicator light 11 to flash when the detected pressure value reaches a preset value. By setting a traction mechanism inside the testing table 1 to drive the base 2 to move laterally left and right at the top of the testing table 1, the mounting plates 3 on both sides of the top of the base 2 and the car seat body 4 at the top of the base 2 can be moved alternately to the inside of the frame 5 for SBR testing.

[0022] The traction mechanism includes a take-up coil 12 and a vertical plate 13. The take-up coil 12 is provided in two sets and is fixed to the left and right sides of the inside of the detection table 1 with bolts. The vertical plate 13 is fixed to the middle position of the bottom end of the base 2 with bolts. Traction rings 14 are welded and fixed to the outer walls of the left and right sides of the vertical plate 13. A traction rope 15 is wound on the winding wheel at the output end of the take-up coil 12, and the end of the traction rope 15 away from the take-up coil 12 is fixedly bolted to the traction ring 14. When one set of take-up coil 12 is started, the traction rope 15 at its output end is wound up, and the other set of take-up coil 12 is started to unwind the traction rope 15 at its output end, so as to pull the vertical plate 13 and drive the base 2 to move laterally left and right through the traction force.

[0023] The clamping mechanism includes clamping blocks 16 and fixing blocks 17. The clamping blocks 16 are provided in four sets and are slidably connected to the top of the clamping plate 3 at the front, back, left and right sides. The fixing blocks 17 are welded and fixed to the side of the clamping blocks 16 away from the car seat body 4. A locking bolt 18 is threaded through the fixing block 17. A locking block 19 is connected to the bottom end of the locking bolt 18. Rotating the locking bolt 18 downwards drives the locking block 19 to descend and abut against the top of the clamping plate 3, thereby positioning and locking the clamping blocks 16. The four sets of clamping blocks 16 are used to clamp and fix the car seat body 4.

[0024] A T-shaped slider 20 is fixed at the bottom of the clamping block 16, and a T-shaped groove 21 is provided at the top of the clamping plate 3. The T-shaped slider 20 is adapted to the T-shaped groove 21 and slides in the T-shaped groove 21, so as to realize the sliding connection of the clamping block 16 at the top of the clamping plate 3.

[0025] The longitudinal adjustment mechanism includes a first lead screw 22 and a longitudinal plate 23. The first lead screw 22 is rotatably connected to the inner side of the frame 5 via a bearing and is driven to rotate by a motor on the rear outer wall of the frame 5. The longitudinal plate 23 is threaded onto the first lead screw 22. The bottom end of the longitudinal plate 23 is fixed to the top of the drive box 6 by bolts. Limiting rods 24 are symmetrically fixed on the inner side of the frame 5. The two sets of limiting rods 24 slide through the longitudinal plate 23 to limit the movement of the longitudinal plate 23, making it more stable during movement. The first lead screw 22 is driven to rotate by the motor, causing the longitudinal plate 23 threaded onto the first lead screw 22 to drive the drive box 6 to move longitudinally back and forth.

[0026] The lateral adjustment mechanism includes a second lead screw 25 and a lateral plate 26. The second lead screw 25 is rotatably connected to the inside of the drive box 6 via a bearing and is driven to rotate by a motor on the left outer wall of the drive box 6. The lateral plate 26 is threaded onto the second lead screw 25. The bottom end of the lateral plate 26 slides through the bottom end of the drive box 6 and is fixed to the top end of the hanging frame 7 by bolts. By clicking to drive the second lead screw 25 to rotate, the lateral plate 26 threaded onto the second lead screw 25 causes the hanging frame 7 at its bottom end to move laterally left and right.

[0027] Rollers are rotatably connected to both sides of the bottom end of the base 2, and the rollers are in contact with the upper surface of the testing table 1 to provide support for the base 2 and make the base 2 move more smoothly. Slide rods 27 are symmetrically fixed at the top of the pressure block 9. The top of the slide rods 27 slides through the hanging frame 7 to limit the pressure block 9 and make it more stable during the lifting process.

[0028] When SBR testing is required during the production and processing of car seats, firstly, a set of car seat bodies 4 to be tested are clamped and fixed on the clamping plates 3 on both sides of the top of the base 2 using clamping mechanisms. Then, the base 2 is driven to move from left to right using a traction mechanism until the left car seat body 4 to be tested moves to the inside of the frame 5 and is below the pressure block 9. Subsequently, the drive box 6 is driven to move longitudinally back and forth to an appropriate position using a longitudinal adjustment mechanism, and the hanging frame 7 is driven to move laterally left and right to an appropriate position using a transverse adjustment mechanism, until the pressure block 9 is adjusted to the corresponding position according to the actual pressure position required by the car seat body 4. At this time, the hydraulic cylinder 8 is activated to drive the pressure block 9 to descend and apply a certain pressure to the car seat body 4 below it. When the SBR sensor 10 inside the car seat body 4 detects… When the pressure value reaches the preset value, the indicator light 11 flashes, indicating that the SBR test of the car seat body 4 is qualified. When the SBR sensor 10 detects that the pressure value is lower than the preset value, the indicator light 11 does not light up, indicating that the SBR test of the car seat body 4 is unqualified. After the test is completed, the hydraulic cylinder 8 is activated to drive the pressure block 9 to rise and reset. Then, the traction mechanism is used to drive the base 2 to move from right to left until the right side of the car seat body 4 to be tested moves to the inside of the frame 5 and is under the pressure block 9. The above pressure test is repeated. At the same time, the car seat body 4 on the left clamping plate 3 is removed and a new car seat body 4 to be tested is clamped. The above steps are repeated to realize the continuous SBR test process of multiple car seat bodies 4, reducing unnecessary waiting time.
