Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic computers, and in particular to an all-in-one machine testing fixture. Background Art
[0002] An all-in-one computer, abbreviated as all-in-one, is a desktop computer that integrates a microprocessor, motherboard, hard disk, screen, speaker, video camera and display into one.
[0003] With the development of electronic technology and the popularization of computers, the application environment of computers has become more and more demanding. Therefore, reliability testing is very important when developing and manufacturing computers, especially shock testing and vibration testing in reliability testing.
[0004] The appearance of the all-in-one product often leaves the first impression on users. All-in-one products with curved and complex shapes are more popular with users. However, the complex appearance of the all-in-one product brings difficulties to the fixation of the impact vibration test specimens.
[0005] The all-in-one machine is characterized by complex shape, and the appearance of the arc is mainly irregular; the connected bracket is even more complex, making the entire appearance irregular and weak in strength. It cannot be clamped directly by a fixture like a conventional desktop. The impact vibration test requires the X, Y, and Z axes to be tested in the positive and negative directions, that is, the six sides of the all-in-one machine need to be placed on the test bench. Normally, the sample needs to be a cubic structure so that it can be clamped easily; the structure is too weak or easily deformed and damaged, and it cannot be clamped directly, because it will be subjected to great force when clamped. If the clamp is loose, it will fall off during the test, causing the test to fail.
[0006] See also Figure 1 , which is a schematic diagram of an existing impact vibration table, which is a common product on the market. The impact vibration table 10 is equipped with fixing bolts 11, fixing nuts 12 and clamp beams 13. When performing impact vibration tests, it is necessary to fix the sample to be tested by adjusting the fixing bolts 11, fixing nuts 12 and clamp beams 13. Figure 1 It can be seen that for all-in-one machines with complex shapes, the fixtures that come with the existing vibration table are usually unable to directly fix the samples, so we are required to design a set of fixtures to assist in testing.

2. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The rectangular body of the upper bracket is provided with a groove structure corresponding to the surface of the upper frame of the all-in-one screen assembly for accommodating and fixing the upper frame of the all-in-one screen assembly; the adjacent ends of the upper bracket corresponding to the left bracket and the right bracket are provided with a concave structure to cooperate with the convex structure of the left bracket and the convex structure of the right bracket, so that they can be inserted and fixed in position when forming a rectangular frame.
3. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The rectangular main body of the lower bracket is provided with a groove-shaped structure corresponding to the surface of the lower frame of the all-in-one screen assembly for accommodating and fixing the lower frame of the all-in-one screen assembly; the adjacent ends of the lower bracket corresponding to the left bracket and the right bracket are provided with a concave structure to cooperate with the convex structure of the left bracket and the convex structure of the right bracket, so that they can be inserted and fixed in position when forming a rectangular frame.
4. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The lower bracket is provided with a notch structure to allow the integrated machine bracket to be placed and passed through.
5. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The rectangular body of the left bracket is provided with a groove structure on the surface corresponding to the left frame of the all-in-one screen assembly for accommodating and fixing the left frame of the all-in-one screen assembly; the adjacent ends of the left bracket that are aligned with the upper bracket and the lower bracket are provided with a convex structure, so that they can be inserted and fixed in position when forming a rectangular frame.
6. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The rectangular body of the right bracket is provided with a groove structure corresponding to the surface of the right frame of the all-in-one screen assembly for accommodating and fixing the right frame of the all-in-one screen assembly; the adjacent ends of the right bracket that are aligned with the upper bracket and the lower bracket are provided with a convex structure, so that they can be inserted and fixed in position when forming a rectangular frame.
7. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The stacking frame is provided with two longitudinally extending stacking frame protrusions on the first surface of the rectangular main body; and a mutually perpendicular transversely extending stacking frame protrusion and a longitudinally extending stacking frame protrusion are provided on the second surface adjacent to the first surface.
8. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The multiple stacked frames have the same shape and size.
9. The all-in-one machine test fixture as claimed in claim 1, characterized in that: The number of the stacked frames is four.
10. The all-in-one machine test fixture according to claim 1, characterized in that: The all-in-one machine fixed by the test fixture includes an all-in-one machine screen component and an all-in-one machine bracket assembled together, and the all-in-one machine screen component and the all-in-one machine bracket are connected and fixed together by a rotating shaft; the all-in-one machine bracket is in the form of a tripod.
