Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts testing equipment, in particular to a vehicle rear seat flipping device for testing. Background Art

[0002] In the automotive manufacturing industry, durability testing of rear seats is an important part of ensuring product quality and passenger safety. Traditional testing methods usually involve fixing the car seat on a test bench and then manually folding it repeatedly to simulate the wear and tear in actual use. However, this method has several limitations. First, since it mainly relies on manual labor for folding, it is not only inefficient but also puts a heavy physical strain on the operator. Long-term repetitive labor can easily lead to fatigue and potential risks of work-related injuries. Second, manual flipping makes it difficult to ensure that the angle and force of each fold are completely consistent, which may affect the accuracy and reliability of the test results. In addition, for vehicles with multiple seats, testing each seat individually not only increases the workload, but also prolongs the entire test cycle, which is not conducive to rapid iteration and product optimization.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0030] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0031] Reference Figure 1-4 A test vehicle rear seat flipping device according to this embodiment is described.

[0032] like Figure 1 and Figure 2 As shown, the device includes an equipment frame 1, with a first platform 2 and a second platform 6 fixed to the front and rear ends of the bottom of the equipment frame 1 respectively. The first platform 2 is fixed to a rear seat 3 to be tested, which includes a center seat 32 and side seats 31 located on both sides of the center seat 32. A movable assembly is installed on the second platform 6, and a test assembly is installed on the movable assembly.

[0033] like Figure 3 and Figure 4 As shown, guide rails 19 are provided on the back of the center seat 32 and the side seats 31. The guide rails 19 include a center vertical rail 195 fixed to the back of the center seat 32 and a side vertical rail 193 fixed to the back of the side seat 31. During the pushing and pulling process of the test assembly, the sliding member at its end slides up and down within the center vertical rail 195 or the side vertical rail 193. When the second telescopic rod 16 in the test assembly is extended to generate a thrust, the sliding member slides from the bottom of the center vertical rail 195 or the side vertical rail 193 to the top position, at which point the center seat 32 or the side seat 31 is flipped downward and engaged; when the second telescopic rod 16 is retracted to generate a pulling force, the sliding member slides from the top of the center vertical rail 195 or the side vertical rail 193 to the bottom position, at which point the center seat 32 or the side seat 31 is flipped upward and opened. This process is repeated to achieve repeated folding of the rear seat 3 to be tested.

[0034] like Figure 4As shown, while achieving the above-mentioned purpose, a first transverse track 194 is also provided on the top of the side vertical track 193. The first transverse track 194 forms an "L" shape when connected to the side vertical track 193. A second transverse track 196 is also provided on the top of the center vertical track 195. The second transverse track 196 forms a "T" shape when connected to the center vertical track 195. The second transverse track 196 is connected to the first transverse track 194. The purpose of using the first transverse track 194 and the second transverse track 196 is that, for example, after the slider slides up and down on the side vertical track 193 to test the side seat 31, the slider continues to slide upward on the side vertical track 193 and connects to the first transverse track 194. At this time, the moving assembly moves horizontally, driving the test assembly to move horizontally, causing the slider to move horizontally from the first transverse track 194 to the second transverse track 196 and slide into the center vertical track 195. At this time, the center seat 32 can be directly folded and tested. Furthermore, the sliding member can also slide transversely into the side vertical track 193 on the other side according to the above method to perform a folding test on the side seat 31 on the other side.

[0035] Furthermore, a lock 197 is provided at the end of the second transverse track 196 that meets the first transverse track 194. The lock 197 secures the first transverse track 194 and the second transverse track 196 together. At this point, the slider can be positioned within the central vertical track 195, and the test assembly can directly carry the central seat 32 and two or one side seats 31 for a folding test.

[0036] like Figure 4 As shown, a second locator 191 and a third locator 192 are provided at the top and bottom of the central vertical track 195 and the side vertical track 193, respectively. The second locator 191 and the third locator 192 are position sensors connected to the controller of the device, which is a PLC controller. When the slider slides up and down on the side vertical track 193 or the central vertical track 195, it stops when it slides to the second locator 191 and the third locator 192. This is a prior art and will not be described in detail here.

[0037] like Figure 2As shown, the moving mechanism includes a positioning seat 4, a drive shaft 10, a driven shaft 11, a motor 7, and a belt 13. There are four positioning seats 4, two in each group, and two groups of positioning seats are located at both ends of the second platen 6. A polished rod 12 is provided between the positioning seats 4 at both ends, and a moving platen 14 is slidably connected to the polished rod 12. The drive shaft 10 and the driven shaft 11 are respectively rotatably arranged in the positioning seats 4 at both ends. The motor 7 is fixed to the positioning seat 4 and is used to drive the drive shaft 10 to rotate. The belt 13 is rotatably connected to the drive shaft 10 and the driven shaft 11, and the top surface of the belt 13 is fixed to the moving platen 14. During operation, the motor 7 drives the drive shaft 10 to rotate, and the cooperation between the drive shaft 10, the driven shaft 11, and the belt 13 causes the belt 13 to rotate. Because the movable platen 14 is fixed to the belt 13 and slidably connected to the polished rod 12 at both ends, the belt 13 can drive the movable platen 14 to repeatedly move laterally on the polished rod 12 when the motor 7 rotates forward and reverse, thereby adjusting the lateral position of the test assembly. During the lateral movement, the sliding member moves within the first transverse track 194 and the second transverse track 196.

[0038] Furthermore, a rear connecting frame 8 is provided on the rear side of the positioning base 4, on which are mounted multiple first positioners 9. These first positioners 9 include a central positioner and side positioners located on either side of the central positioner. The central positioner corresponds to the central vertical track 195, while the side positioners correspond to the side vertical tracks 193. This ensures that when the slider is adjusted to the central positioner, it is positioned on the central vertical track 195, while when adjusted to the side positioners, it is positioned on the side vertical tracks 193. Similarly, the first positioners 9 serve as position sensors connected to the controller of this device.

[0039] like Figure 2 As shown, the test assembly includes a column 5, a slide 20 is provided on the column 5, and a second telescopic rod 16 is provided on the column 5. The fixed end of the second telescopic rod 16 is provided with a second slider 21. The second slider 21 is slidably connected to the slide 20, allowing the second telescopic rod 16 to slide along the height direction of the column. A first telescopic rod 15 is hinged at the bottom of the column 5, and the telescopic end of the first telescopic rod 15 is hinged to the second telescopic rod 16. During specific implementation, the telescopic movement of the first telescopic rod 15 and the second telescopic rod 16 are coordinated with each other. Specifically, when the first telescopic rod 15 is pushed forward, it pushes the second telescopic rod 16 to move upward. At this time, the second telescopic rod 16 is pushed forward synchronously, causing the slider to slide from a low point to a high point within the side vertical track 193 or the center vertical track 195, causing the center seat 32 or the side seat 31 to fold downward. On the contrary, when the first telescopic rod 15 retracts, the second telescopic rod 16 is pulled downward. At this time, the second telescopic rod 16 retracts synchronously, causing the sliding member to slide from a high point to a low point in the side vertical track 193 or the center vertical track 195, so that the center seat 32 or the side seat 31 is folded upward and unfolded.

[0040] In this embodiment, the second telescopic rod 16 and the first telescopic rod 15 can be selected from a variety of structures, including electric telescopic rods, air cylinders, or hydraulic cylinders, preferably electric telescopic rods.

[0041] like Figure 2 As shown, a sliding member is provided at the end of the telescopic end of the second telescopic rod 16, and the sliding member includes a first slider 17 fixed to the end of the telescopic end of the second telescopic rod 16, and a rolling ball 18 is provided on the first slider 17. The first slider 17 and the rolling ball 18 are slidably connected in the guide rail 19.

[0042] Working principle: fix the rear seat 3 to be tested on the second platform 6, and fix the guide rail 19 on the rear back surface of the rear seat 3 to be tested (pay attention to keep the first horizontal rail 194 and the second horizontal rail 196 parallel to each other during installation so that they can be docked); press down a chair back, and when the moving assembly moves, slide the slider into the first horizontal rail 194 or the second horizontal rail 196, then lift the pressed chair back, and the preparation work is completed.

[0043] When it is necessary to inspect a single seat, the lock 197 is unlocked, and the movable assembly moves laterally into the corresponding first transverse track 194 and second transverse track 196. The first telescopic rod 15 and second telescopic rod 16 then retract, causing the slider to slide into the side vertical track 193 or the center vertical track 195. When it is necessary to inspect all seats, the lock 197 is closed, connecting the center seat 32 and the side seat 31 into one.

[0044] During testing, when the second telescopic rod 16 extends to generate a thrust, the slider slides from the bottom of the central vertical track 195 or the side vertical track 193 to the top position, at which point the central seat 32 or the side seat 31 is flipped downward and locked; when the second telescopic rod 16 retracts to generate a tension, the slider slides from the top of the central vertical track 195 or the side vertical track 193 to the bottom position, at which point the central seat 32 or the side seat 31 is flipped upward and opened. This process is repeated to achieve repeated folding of the rear seat 3 to be tested.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
