Description

Technical Field

[0001] The present invention relates to the technical field of automobile testing equipment, and in particular to a device for testing the shift limit function of a child seat. Background Art

[0002] Child seats, especially child car seats, are crucial for ensuring child safety while riding in a vehicle. With technological advancements and rising safety standards, testing the quality and performance of child seats has become increasingly important. The position limit function is a fundamental component of child seat testing, used to assess the seat's structural stability and its ability to reliably position the child.

[0003] However, there are usually some problems in the daily use of ordinary child seat limit function test devices. With the development of science and technology, technicians in related fields have also made a lot of optimizations to the child seat limit function test devices to solve some problems that different consumer groups care about. In order to make a more accurate comparison, for example, Chinese patent No. CN208751873U discloses a car seat safety performance test device, including an adjustment device, the upper part of the adjustment device is fixedly connected to a support rod, the adjustment device is fixedly connected to a first support plate through the support rod, the upper end of the first support plate is threadedly connected to the car seat through a bolt, and the car seat is connected by bolts, which can facilitate users to quickly disassemble and firmly install the seat to prevent the seat from slipping during the test. The lower part of the adjustment device is fixedly connected to a detection device, and the bottom end of the detection device is slidably connected to symmetrically distributed tracks. The above-mentioned existing technology has multiple detection functions and is low in cost. It can quickly adjust the detection direction of the seat during the test and can also detect the safety performance of the seat when it rolls over.

[0004] However, the above-mentioned car seat safety performance testing device still has some shortcomings in actual use:

[0005] 1. The above-mentioned automobile seat safety performance testing device is connected to the automobile seat by bolts, which can facilitate users to quickly disassemble and firmly install the seat, preventing the seat from slipping during the test. However, the method of fixing the seat by bolts cannot fully restore the state of the seat in the car, thereby affecting the subsequent seat testing results.

[0006] 2. The above-mentioned automobile seat safety performance testing device uses an electric motor to slide the device inside the track through a belt drive, thereby measuring the safety of the automobile seat in any direction. However, simply sliding the device inside the track through the belt drive cannot well simulate the state of the automobile when driving, resulting in an incomplete test and inaccurate test.

[0007] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing child seat limit function testing device. Summary of the Invention

[0042] Reference Figure 4 As shown, that is, the backrest support unit 37 in the present application; specifically, the backrest support unit 37 includes a support plate 370, an adjustment block 371, a lifting slot 372 and a fixed plate 373. The support plate 370 is symmetrically rotatably arranged in the support platform 10, and the support plate 370 is used to support the backrest of the child seat; an adjustment block 371 is slidingly arranged on the side of the support plate 370 close to the T-shaped slider 30, and a lifting slot 372 for the adjustment block 371 to slide is provided on the support plate 370.

When the T-shaped slider 30 moves, it can drive the fixed plate 373 to move together, and when the fixed plate 373 moves, it can drive the adjustment block 371 to move together.

[0043] During the specific implementation process, when the T-shaped slider 30 moves, it can drive the fixed plate 373 to move together. When the fixed plate 373 moves, it can drive the adjustment block 371 to move together under the restriction of the lifting slot 372. When the adjustment block 371 moves, it drives the support plate 370 to rotate, thereby adjusting the inclination angle of the support plate 370, and can also fix the backrest of the child seat, thereby more realistically simulating the use environment of the child seat and improving the accuracy of the test.

[0044] Reference Figure 5 As shown, that is, the reinforcement mechanism 4 in the present application; specifically, the reinforcement mechanism 4 includes a square box 40, a pressure plate 41, a second spring 42, a top column 43, a telescopic tube 44 and a telescopic airbag 45. The square box 40 is provided at the bottom of the square frame 32. When the square box 40 moves, it can drive the square frame 32 to move together; a pressure plate 41 is slidingly provided in the square box 40, and the pressure plate 41 can move under the restriction of the square box 40; a second spring 42 is provided between the pressure plate 41 and the inner wall of the square box 40, and the second spring 42 can always provide an upward thrust for the pressure plate 41; the square box A top column 43 is provided on the top of the pressure plate 41 in the sliding part 32, and when the top column 43 moves, the pressure plate 41 can be driven to move together; the bottom of the square box 40 and the T-shaped slider 30 are connected by a telescopic tube 44, and the gas at the bottom of the pressure plate 41 in the square box 40 can enter the T-shaped slider 30 through the telescopic tube 44; a telescopic airbag 45 is provided on the side of the top of the T-shaped slider 30 near the top column 43, and the gas in the T-shaped slider 30 can enter the telescopic airbag 45, and the telescopic airbag 45 can fit tightly with the child seat to further fix the child seat.

[0045] During the specific implementation process, when the operator places the child seat in the center of the support platform 10, the child seat drives the top column 43 to move downward by its own gravity. When the top column 43 moves downward, it can drive the pressure plate 41 to move downward under the restriction of the square box 40. When the pressure plate 41 moves downward, the gas at the bottom of the pressure plate 41 can be pressed into the T-shaped slider 30 through the telescopic tube 44. The gas in the T-shaped slider 30 can enter the telescopic airbag 45. Through the telescopic airbag 45, the child seat can be more firmly fitted to enhance the fixing effect.

[0046] Reference Figure 6As shown, the test mechanism 2 in the present application; specifically, the test mechanism 2 includes a test track 20, a universal wheel 21, an adjustment slot 22 and a speed adjustment unit 23. A plurality of test tracks 20 are provided on the base 1, and universal wheels 21 located in the test track 20 are provided at the four corners of the bottom of the square box 40. The square box 40 can move along the test track 20 through the universal wheel 21, thereby simulating the working environment of the child seat; an adjustment slot 22 for the universal wheel 21 to move in a plurality of test tracks 20 is provided on the base 1, and the square box 40 can move to other test tracks 20 through the adjustment slot 22; a speed adjustment unit 23 is also provided on the base 1, and the speed adjustment unit 23 is used to adjust the moving speed of the square box 40 in the test track 20.

[0047] During the specific implementation process, after the child seat is fixed, the square box 40 is first moved to the required test track 20 through the adjustment slot 22, and then the moving speed in the test track 20 is adjusted using the speed adjustment unit 23. Finally, the square box 40 is moved along the test track 20 through the universal wheel 21, thereby simulating turns of different magnitudes during the driving process of the car, and can better test child seats in different working conditions.

[0048] Reference Figure 7 As shown, the speed adjustment unit 23 in the present application; specifically, the speed adjustment unit 23 includes a strip plate 230, a push plate 231, a spring three 232, a blocking assembly 233, a retractable threaded rod 234 and a connecting plate 235. The top of the base 1 is provided with a strip plate 230, and the top of the base 1 is slidably provided with a push plate 231 located on the side of the square box 40 close to the strip plate 230. The push plate 231 is used to push the square box 40 to move; the push plate 231 and the strip plate 230 are connected by multiple spring three 232, and the spring three 232 always provides the push plate 231 with a thrust toward the square box 40; the bottom The top of the seat 1 is slidingly provided with multiple blocking components 233 located on the side of the universal wheel 21 away from the push plate 231. The blocking components 233 act as a protective barrier to prevent the square box 40 from accidentally moving the child seat; a retractable threaded rod 234 is rotatably provided inside the base 1 and is located below the test track 20. A connecting plate 235 connected to the blocking component 233 is fitted on the retractable threaded rod 234. The retractable threaded rod 234 can rotate under the restriction of the base 1. When the retractable threaded rod 234 rotates, it can drive the connecting plate 235 to move together. When the connecting plate 235 moves, it can drive the blocking component 233 to move together.

[0049] In a specific implementation process, by rotating the retractable threaded rod 234, the retractable threaded rod 234 can rotate under the restriction of the base 1. When the retractable threaded rod 234 rotates, it can带动 the connecting plate 235 to move together. When the connecting plate 235 moves, it can带动 the blocking component 233 to move together. When the blocking component 233 moves, it can带动 the square box 40 to move together. When the square box 40 moves, it can带动 the push plate 231 to move together. By挤压 the spring three 232 with the push plate 231, the rebound force of the spring three 232 is determined, and进而 the speed of the square box 40 and the child seat in the test track 20 is changed.

[0050] Refer to Figure 8 and Figure 9 As shown, that is, the blocking component 233 in this application; the blocking component 233 includes a blocking plate 2330, a U-shaped plate 2331, a rotating plate 2332, a C-shaped rod 2333, a limiting block 2334, a gear position hole 2335, and a selection rod 2336. A plurality of blocking plates 2330 are slidably arranged on the bottom on the side of the universal wheel 21 away from the push plate 231. The blocking plate 2330 is connected to the connecting plate 235. When the connecting plate 235 moves, it can带动 the blocking plate 2330 to move together; a U-shaped plate 2331 is arranged between the blocking plates 2330 and inside the test track 20. When the blocking plate 2330 moves, it can带动 the U-shaped plate 2331 to move together; a rotating plate 2332 is rotatably arranged inside the U-shaped plate 2331. The rotating plate 2332 can限制 the movement of the square box 40, and the rotating plate 2332 can rotate under the restriction of the U-shaped plate 2331; a C-shaped rod 2333 is arranged on the top of the blocking plate 2330. When the blocking plate 2330 moves, it can带动 the C-shaped rod 2333 to move together; a limiting block 2334 is rotatably arranged on the C-shaped rod 2333 on the side of the blocking plate 2330 away from the universal wheel 21. The limiting block 2334 can rotate under the restriction of the C-shaped rod 2333. When the C-shaped rod 2333 moves, it can带动 the limiting block 2334 to move together; a plurality of gear position holes 2335 are opened on the base 1. A selection rod 2336 is inserted into one of the gear position holes 2335. When the selection rod 2336抵触 the limiting block 2334, it can带动 the limiting block 2334 to rotate.

[0051] When the cam 2332 is in contact with the restraining block 2334, the restraining block 2334 is released from the restraining block 2334, thereby releasing the restraining block 2334 from rotating.

[0052] Example 2:

[0053] Reference Figure 10 As shown, on the basis of Example 1, in order to facilitate the operator to more accurately control the rotation distance of the retracting threaded rod 234, during the specific implementation of this solution, a drive motor 5 is provided on the side of the retracting threaded rod 234 away from the blocking plate 2330 through the motor housing. When the drive motor 5 is started, the retracting threaded rod 234 rotates accordingly.

[0054] Reference Figure 10 As shown, in order to prevent the square box 40 and the child seat from colliding and causing damage to the square box 40 and the child seat when they move to the end in the test track 20, during the specific implementation of this solution, a buffer plate 6 is provided on the top of the base 1 and on the side of the test track 20 away from the drive motor 5, and a buffer pad 60 is provided on the side of the buffer plate 6 close to the test track 20. When the square box 40 drives the support platform 10 and the child seat to move to the end in the test track 20, the support platform 10 and the child seat collide with the buffer pad 60 to prevent damage to the support platform 10 and the child seat.

[0055] During operation: In the first step, when the operator places the child seat at the center of the support platform 10, the child seat uses its own gravity to guide the top column 43 to move downward. When the top column 43 moves downward, it can drive the pressure plate 41 to move downward under the restriction of the square box 40. When the pressure plate 41 moves downward, the gas at the bottom of the pressure plate 41 can be pressed into the T-shaped slider 30 through the telescopic tube 44. The gas in the T-shaped slider 30 can enter the telescopic airbag 45, and through the telescopic airbag 45, it can fit tightly with the child seat to further fix the child seat.

[0056] Step 2: When the operator places the child seat on the top of the support platform 10, the operator can drive the tightening ring 34 to shrink under the restriction of the limit frame 35 by rotating the tightening threaded rod 36. When the tightening ring 34 shrinks, it can drive the T-shaped slider 30 to move toward the center of the support platform 10, thereby fixing the child seat through the T-shaped slider 30; at the same time, when the T-shaped slider 30 moves, it can drive the fixing plate 373 to move together. When the fixing plate 373 moves, it can drive the adjusting block 371 to move together under the restriction of the lifting slot 372. When the adjusting block 371 moves, it drives the support plate 370 to rotate, thereby adjusting the inclination angle of the support plate 370, and can also fix the backrest of the child seat, thereby more realistically simulating the use environment of the child seat and improving the accuracy of the test.

[0057] Step 3: After the child seat is fixed, first move the square box 40 to the required test track 20 through the adjustment slot 22, and then when the driving motor 5 rotates, it can drive the retracting threaded rod 234 to rotate together, so that the operator can more accurately control the rotation distance of the retracting threaded rod 234. When the retracting threaded rod 234 rotates, it can drive the connecting plate 235 to move together. When the connecting plate 235 moves, it can drive the blocking plate 2330 to move together. When the blocking plate 2330 moves, it can drive the square box 40 to move together. When the square box 40 moves, it can drive the push plate 231 to move together, thereby squeezing the spring three 232 through the push plate 231.

[0058] Step 4: When the square box 40 compresses the spring 3 232, the movement of the square box 40 is restricted by the rotating plate 2332; when testing is required, the operator inserts the selection rod 2336 into the corresponding gear hole 2335, and then retracts the threaded rod 234 to drive the square box 40 to move, which can drive the blocking plate 2330, the U-shaped plate 2331 and the rotating plate 2332 to move together. When the blocking plate 2330 moves, it can drive the U-shaped rod 2333 to move together. When the U-shaped rod 2333 moves, it can drive the limiting block 2334 to move together. When the selection rod 2336 conflicts with the limiting block 2334, it can drive the limiting block 2334 to move together. Block 2334 rotates, and when the limiting block 2334 rotates, the rotation restriction on the rotating plate 2332 is released, so that the rotating plate 2332 rotates, so that the rotating plate 2332 no longer hinders the movement of the square box 40, and the square box 40 and the child seat are moved along the test track 20. When the square box 40 drives the support platform 10 and the child seat to move to the end in the test track 20, the support platform 10 and the child seat collide with the buffer pad 60 to prevent damage to the support platform 10 and the child seat, thereby simulating different amplitudes of turns during the driving of the car, and better testing child seats in different working conditions.
