Description

Technical Field

[0001] This utility model relates to the field of computer testing, and in particular to a testing fixture for portable computers. Background Technology

[0002] With the rapid development of electronic technology and the deepening of global digitalization, portable computers (such as laptops and tablets) are widely used in various fields. Today, users not only use them in stable office or home environments, but also frequently carry them through various mobile environments, such as on various modes of transportation, in various outdoor work sites, and even while walking. To adapt to complex and diverse application scenarios / environments, the requirements for the structural strength and reliability of internal components of portable computers have also increased.

[0003] Currently, reliability testing of portable computers during the R&D / manufacturing phase, especially shock and vibration testing simulating transportation, drops, impacts, and long-term vibration conditions, has become an indispensable part of ensuring product quality. Meanwhile, as market competition intensifies, the appearance of portable computers has become a crucial factor in attracting users. Current design trends favor streamlined curves and other complex curved surfaces. While these designs enhance product aesthetics and user experience, they also present challenges for reliability testing. For example, vibration tables and impact tables are typically equipped with standardized, universal fixtures designed primarily for samples with regular geometric shapes, making it difficult to effectively adapt to the complex and varied curved surfaces of portable computer products. Forcibly fixing the product to the fixture not only fails to ensure a rigid connection between the test product and the fixture during testing, leading to distortion in the transmission of test stimuli and affecting the accuracy and validity of the test data, but more seriously, the direct rigid clamping or support of the fixture can easily cause irreversible damage such as indentations, scratches, or even structural deformation on the product's delicate housing. This damage can not only interfere with the correct judgment of the test failure mode, but may also directly damage the functional prototype, causing unnecessary losses and increasing the cost of research and development and production.

[0004] Therefore, there is an urgent need to design and develop a dedicated test fixture (also known as a jig) that can be used for shock / vibration testing of portable computers with complex appearances. Summary of the Invention

[0005] The purpose of this invention is to provide a test fixture for portable computers that is suitable for shock / vibration testing of portable computers with complex appearances.

[0006] To achieve the above objectives, this utility model provides a test fixture for a portable computer, comprising a first bracket, a second bracket, a third bracket, and a fourth bracket. The first bracket and the fourth bracket are arranged opposite to each other, as are the second bracket and the third bracket. The second bracket has several second fixing grooves on its surface opposite to the third bracket, and the third bracket has several third fixing grooves on its surface opposite to the second bracket. The several second fixing grooves and the several third fixing grooves respectively cooperate to fix different test samples. The first bracket and the fourth bracket are respectively connected between the second bracket and the third bracket to form a U-shaped structure.

[0007] Several second fixing grooves have different specifications, and several third fixing grooves have different specifications. One second fixing groove and the corresponding third fixing groove form a set of test prototype mounting slots, so that the set of test prototype mounting slots is suitable for fixing test prototypes with different appearance shapes.

[0008] The first bracket has a first protrusion at each end, the fourth bracket has a fourth protrusion at each end, the second bracket has a second groove at each end of the second fixing groove, and the third bracket has a third groove at each end of the third fixing groove. The first bracket, the second bracket, the third bracket, and the fourth bracket form a U-shaped structure through the cooperation of the first protrusion, the fourth protrusion, the second groove, and the third groove.

One first fixed through slot, together with the corresponding second fixed groove and the third fixed groove, forms a set of test prototype mounting slots. Thus, the array of test prototype mounting slots is suitable for fixing test prototypes with different appearances.

[0012] The fourth bracket has several second fixing slots on its side facing away from the first bracket. When the fourth bracket is flipped so that the several second fixing slots face the first bracket, they can be used to fix different test prototypes by cooperating with several second fixing grooves and several third fixing grooves respectively. The several second fixing slots have different specifications. One second fixing slot, together with the corresponding second fixing groove and third fixing groove, forms a set of test prototype mounting slots. Thus, the set of test prototype mounting slots is suitable for fixing test prototypes with different appearances.

[0014] The portable computer is a laptop computer. The second fixing groove includes a second opening and closing fixing groove and a second closing fixing groove. The third fixing groove includes a third opening and closing fixing groove and a third closing fixing groove. The second closing fixing groove and the third closing fixing groove are used to fix the test prototype in the closed state, and the second opening and closing fixing groove and the third opening and closing fixing groove are used to fix the test prototype in the open state. The second opening and closing fixing groove and the third opening and closing fixing groove are L-shaped grooves formed by a horizontal groove extending from the direction of the fourth bracket to the direction of the first bracket and a vertical groove extending from the end of the horizontal groove near the first bracket to the direction perpendicular to the U-shaped plane. The end of the vertical groove away from the horizontal groove passes through the bracket to fix the display screen of the test prototype in the open state.

[0015] The fourth bracket has several first fixing slots on its surface relative to the first bracket, which cooperate with several second fixing grooves and several third fixing grooves. The several first fixing slots cooperate with several second fixing grooves and several third fixing grooves respectively to fix different test prototypes. The first fixing slot includes a first opening and closing fixing slot and a first closing fixing slot. The first opening and closing fixing slot cooperates with the corresponding second opening and closing fixing groove and the third opening and closing fixing groove to fix the test prototype in the open state. The first closing fixing slot cooperates with the corresponding second closing fixing groove and the third closing fixing groove to fix the test prototype in the closed state.
