[0002] Laptops, also known as portable computers, handheld computers, or lap computers, are characterized by their small size. More convenient to carry than desktop computers, they are small, portable personal computers. Today's laptops are diversifying based on their intended use: netbooks are geared towards everyday office work and watching movies; business laptops prioritize stability, low power consumption, and longer battery life; home laptops offer good performance and high cost-effectiveness; and gaming laptops are specifically designed for a smaller group of people who want to play games on the go.

[0003] In the laptop industry, the hinge and casing of a laptop are generally glued together. During the gluing process, factors such as insufficient gluing time, insufficient compression time, and insufficient adhesive strength can affect the lifespan of the hinge, thus affecting the lifespan of the laptop and causing defective products. Therefore, it is necessary to test the laptop hinge during the production process. Currently, testing is generally conducted using assembled laptops, which are opened and closed multiple times. However, this testing method is costly and requires repeated opening and closing of the laptop, resulting in a long testing time. Summary of the Invention

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] This utility model discloses a device for testing the lifespan of a notebook computer hinge, such as... Figure 1-4 As shown, the test platform 1 is included. The laptop casing 2 is placed and attached to the upper surface of the test platform 1. The casing 2 can be an A-shell or a D-shell of the laptop, as A-shells or D-shells are generally used to install hinges. A mounting bracket 11 is fixedly mounted on the upper surface of the test platform 1. A pressure plate 111 is provided on the mounting bracket 11, located directly above the casing 2. A pressing component is provided on the mounting bracket 11 to drive the pressure plate 111 towards or away from the casing 2. Specifically, the pressing component includes a pressing cylinder 112 fixedly mounted on the mounting bracket 11. The pressing cylinder 112 is arranged along a plane perpendicular to the casing 2. The piston rod of the pressing cylinder 112 is fixedly connected to the pressure plate 111. When the operator places the casing 2 on the test platform 1, the piston rod of the pressing cylinder 112 extends, driving the pressure plate 111 to press down and hold the casing 2 in place.

[0022] In addition, two pull-out blocks 31 are provided on the test bench 1, and two rotating shafts are provided on the housing 2. The two pull-out blocks 31 correspond to the two rotating shafts. A certain gap exists between a part of the rotating shaft and the housing 2. The pull-out blocks 31 are inserted into the gap between the housing 2 and the rotating shaft. At the same time, the test bench 1 is provided with a driving component for driving the pull-out blocks 31 to pull the rotating shafts. Specifically, the driving component includes a driving cylinder 3 provided on the test bench 1. The driving cylinder 3 is arranged in a plane perpendicular to the housing 2, and the piston rod of the driving cylinder 3... Fixedly connected to the pull block 31, the operator places the housing 2 on the test bench 1 and pushes it forward so that the pull block 31 is inserted between the housing 2 and the rotating shaft. After the pressure plate 111 presses down on the housing 2, the piston rod of the drive cylinder 3 extends, driving the pull block 31 to pull up the rotating shaft. The magnitude of the force pulling up the rotating shaft can be preset. After five seconds, the piston rod of the drive cylinder 3 retracts, and the test ends. If the rotating shaft falls off or loosens within five seconds, it indicates that there is a problem with the product quality; otherwise, there is no problem with the product quality.

[0023] In addition, two mounting blocks 12 are provided on the test bench 1, and two drive cylinders 3 are fixedly installed on the two mounting blocks 12 respectively. An adjustment groove 13 is provided on the test bench 1 along the length of the housing 2. A fastening bolt is connected between the mounting block 12 and the adjustment groove 13. The screw of the fastening bolt moves through the mounting block 12 and the adjustment groove 13 and extends to the bottom of the test bench 1. The screw of the fastening bolt is threaded with a fastening nut. The fastening nut fits against the bottom of the test bench 1, and the screw head of the fastening bolt fits against the top of the mounting block 12. When the operator needs to adjust the position of the two pull blocks 31, the operator loosens the fastening bolt and then moves the mounting block 12 to adjust the position of the pull blocks 31, so as to easily adapt to housings 2 of different sizes and make the pull blocks 31 align with the rotating shaft of housings 2 of different sizes. In addition, a positioning groove 14 is provided on the test bench 1 along the length of the shell 2. The mounting block 12 slides and engages with the positioning groove 14. The positioning groove 14 can position the mounting block 12, so that the mounting block 12 is not prone to displacement after movement.

[0024] In addition, the test bench 1 is equipped with multiple positioning blocks 15, which abut against three sides of the housing 2. After the operator places the housing 2 on the test bench 1, the positioning blocks 15 can quickly and accurately position the housing 2. Furthermore, the test bench 1 has multiple adjustment slots 16, which are arranged in directions close to or away from the housing 2. A fixing bolt connects the positioning block 15 to the adjustment slot 16. The screw of the fixing bolt moves through the positioning block 15 and the adjustment slot 16 and extends to the bottom of the test bench 1. A fixing nut is threaded onto the screw of the fixing bolt, which fits against the bottom of the test bench 1. The head of the fixing bolt fits against the top of the positioning block 15. When the operator needs to adjust the position of the positioning block 15, the operator loosens the fixing bolt and then moves the positioning block 15 to adjust its position, thus easily adapting it to housings 2 of different sizes. In addition, a limiting groove 17 is provided on the test bench 1. The limiting groove 17 is set in the direction of approaching or away from the housing 2. The positioning block 15 is slidably connected to the limiting groove 17. The limiting groove 17 can play a positioning role for the positioning block 15, so that the positioning block 15 is not easy to deviate after moving.

[0025] The implementation principle of the notebook hinge life testing device according to this utility model embodiment is as follows: The operator places the housing 2 on the test platform 1 and pushes it forward so that the pulling block 31 is inserted between the housing 2 and the hinge. The pressing cylinder 112 drives the pressure plate 111 to press the housing 2. Then, the piston rod of the driving cylinder 3 extends, driving the pulling block 31 to pull up the hinge. After five seconds, the piston rod of the driving cylinder 3 retracts, and the test ends. If the hinge falls off or loosens within five seconds, it indicates that there is a problem with the product quality. Otherwise, there is no problem with the product quality. The whole testing process is convenient and quick. It only needs to test the A shell or D shell of the notebook. The testing cost is low. The whole process of testing the hinge is fast, continuous, and highly reliable. The device has the advantages of simple overall structure, easy implementation, low production cost, and easy operation by workers.
