DETAILED DESCRIPTION

[0021] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 5 The present invention provides a test device for automobile seat performance, comprising a test platform 1, a first guide rail 2 and a second guide rail 3. A movable groove 4 is provided at the center of the test platform 1. A sliding frame 5 is provided in the movable groove 4. The sliding frame 5 is connected to the inner wall of the movable groove 4 by sliding left and right. A placement plate 6 for placing a seat is provided in the sliding frame 5. The placement plate 6 is connected to the inner wall of the sliding frame 5 by sliding back and forth. The first guide rail 2 is provided on the left and right sides of the movable groove 4. The second guide rail 3 is provided on the front and rear ends of the first guide rail 2. The first guide rails 2 on both sides are connected to each other through the second guide rail 3 to form a "mouth"-shaped frame structure. A first sliding component is provided in the first guide rail 2 to drive the second guide rail 3 to move toward each other along the front and rear directions. Fixed plates 7 are provided at the left and right ends of the second guide rail 3 respectively. A second sliding component is provided in the second guide rail 3 to drive the fixed plate 7 to move toward each other along the left and right directions.

[0023] Place the vehicle seat on the placement plate 6, see Figure 1 and Figure 5, taking the seat slide 15 located on the left and right sides of the placement plate 6, and the placement plate 6 located on the upper left position of the movable groove 4 as an example, the first sliding assembly is started to drive the second guide rails 3 on the upper and lower sides to move toward the center. Since the seat slide 15 is located at the upper side, the upper second guide rail 3 will preferentially abut against the seat slide 15. Under the friction between the seat slide 15 and the top surface of the placement plate 6, the upper second guide rail 3 will drive the car seat and the placement plate 6 to move toward the center of the sliding frame 5. When the lower second guide rail 3 is about to approach the seat slide 15, the first sliding assembly is closed; at this time, the second sliding assembly is started to drive the fixed plates 7 on the left and right sides to move toward the center. Since the seat slide 15 is located on the left, the upper and lower sets of second guide rails 3, the fixed plate 7 on the left side will first contact the seat slide rail 15, driving the car seat and the sliding frame 5 to move toward the center of the movable groove 4 until the fixed plates 7 on the left and right sides abut against the left and right ends of the seat slide rail 15, closing the second sliding assembly, and then starting the first sliding assembly again to make the upper and lower groups of second guide rails 3 abut against the front and rear ends of the seat slide rail 15, and the car seat is fixed by abutting and fixing the outer wall of the slide rail in four directions. After adjustment of the test platform 1, various types of car seats are always located in the center of the movable groove 4 after being fixed. It only needs to install the test device on the center line of the movable groove 4 to test various types of car seats, thereby improving the test efficiency.

[0024] The first sliding assembly includes a first driving shaft 8, both ends of which are provided with external threads in opposite directions, the second guide rail 3 is sleeved on both ends of the first driving shaft 8 and is threadedly connected to the external threads in a one-to-one manner, and the first guide rail 2 is also provided with a first motor 9 that drives the first driving shaft 8 to rotate.

[0025] The second sliding assembly includes a second drive shaft 10, both ends of which are provided with external threads in opposite directions. The fixing plate 7 is sleeved on both ends of the first drive shaft 8 and is threadedly connected to the external threads in a one-to-one manner. The second guide rail 3 is also provided with a second motor 11 for driving the second drive shaft 10 to rotate.

[0026] The output shaft of the first motor 9 is coaxially connected to the first drive shaft 8 .

[0027] The second motor 11 is arranged at the top of the second guide rail 3. A driving cavity 12 is provided inside the second guide rail 3. A bevel gear set meshing with each other is provided in the driving cavity 12. The bevel gear set includes a first bevel gear 13 and a second bevel gear 14. The first bevel gear 13 is coaxially connected to the output shaft of the second motor 11, and the second bevel gear 14 is coaxially connected to the second drive shaft 10.

[0028] The two sets of first motors 9 are synchronously controlled to start and stop, and to rotate forward and reverse through the PLC controller, and can drive the second guide rails 3 to move toward each other through the external threads in opposite directions set at both ends of the first drive shaft 8. The two sets of second motors 11 are synchronously controlled to start and stop, and to rotate forward and reverse through the PLC controller, and the rotational force of the second motors 11 in the vertical direction is converted into rotational force in the horizontal direction through the bevel gear set, thereby driving the fixed plates 7 on both sides to move toward each other.

[0029] The movable groove 4 and the sliding frame 5 are both provided with sliding grooves, the sliding frame 5 is slidably connected to the movable groove 4 via the sliding grooves, and the placement plate 6 is slidably connected to the sliding frame 5 via the sliding grooves.
