Description

Technical Field

[0001] The utility model belongs to the field of vibration test fixtures in environmental screening tests, and in particular relates to an installation fixture for vibration testing of all-in-one equipment with a screen. Background Art

[0002] At present, equipment with screens is developing towards high integration, lightweight, individualization, intelligence and systematization. The vibration fixtures owned by relevant mechanical testing laboratories cannot effectively meet the production needs of efficient and safe vibration tests for all-in-one equipment with screens.

[0003] Current vibration tests for integrated devices with integrated displays (IEDs) suffer from complex testing conditions and relatively fragile experimental characteristics. Existing fixtures are inefficient to install and are prone to resonance during testing. Resonance testing can even damage the equipment. This solution simplifies the installation method and reduces unnecessary fixture components, thereby reducing the potential for resonance points during related experiments. Summary of the Invention

[0011] Furthermore, the four positioning corners are rectangular mounting plates, through holes are provided on the four positioning corners for installation and positioning of the fixture, and threaded holes are provided for setting up the all-in-one machine with a screen.

[0012] Furthermore, protective corner blocks are provided on the four positioning corners.

[0013] Furthermore, grooves are provided on the four corners of the positioning member for fixing the downward-pressing expansion locking member.

[0014] Furthermore, the downward-pressing expansion locking component is suspended in the air, and a soft cushion layer is provided inside.

[0015] Compared with the prior art, the present invention has the following significant advantages:

[0016] The mounting fixture of the utility model can reduce the contact surface between the fixture installation and the vibration table by positioning the four corners and strengthening the suspended setting of the slats, thereby reducing the possibility of resonance points in the fixture during the experiment;

[0017] In addition, through holes are set on the four corners for the installation and positioning of the fixture, and threaded holes are set for setting the all-in-one machine with a screen.

The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the innovative concept of the present invention.

[0021] Example

[0022] Combine Figure 1 , a mounting fixture for vibration testing of an all-in-one device with a screen, comprising four positioning corners 1, a reinforcing slat 3, and a downward-pressing, expanding, and locking component 4;

[0023] In this embodiment, the positioning corners 1 are rectangular mounting plates with a height of 12 mm. Through holes are provided on the positioning corners 1 for the installation and positioning of the clamp, and threaded holes are provided for the installation of the all-in-one machine with a screen. In this embodiment, three through holes are provided for the installation and positioning of the clamp, and through threaded holes are provided for the installation of the all-in-one machine with a screen. In addition, protective guard angles are provided on the outside of the through threaded holes of the positioning corners 1. The height of the protective guard angles is 10 mm and the thickness of the protective guard angles is 3 mm to prevent the all-in-one machine from falling off the bottom plate.

[0024] Reinforcement slats 3 are provided between each of the four positioning corners 1. The reinforcement slats 3 are symmetrically arranged to form the frame of the clamp. The reinforcement slats 3 are connected and fixed by the four positioning corners 1.

[0025] In this embodiment, the reinforcing slats 3 include a central reinforcing slat and surrounding reinforcing slats; the central reinforcing slats and the surrounding reinforcing slats are two lightweight suspended reinforcing slats with a symmetrical structure, and the surrounding reinforcing slats are connected and fixed by positioning the four corners 1, and the central reinforcing slats are connected to the surrounding reinforcing slats.

[0026] In addition, the central reinforcement strip and the surrounding reinforcement strips are fixedly connected by installing and positioning four-side reinforcement members 2.

[0027] In this embodiment, the central reinforcement strip and the surrounding reinforcement strips are 4 mm thick, 300 mm long, and 180 mm wide.

[0028] A downward pressing and expanding locking component 4 is provided between the four positioning corners 1, and a rectangular groove is provided on the four positioning corners 1 for fixing the downward pressing and expanding locking component 4. The rectangular groove has a depth of 4 mm, a width of 25 mm, and a length of 31 mm.

[0029] The downward-pressing, expanding, and locking component 4 is 4 mm thick and is vertically connected to the rectangular groove of the bottom plate and is fixed to the threaded hole in the groove with screws. The downward-pressing, expanding, and locking component 4 is suspended in the air, and a soft cushion layer is provided on the internal all-in-one screen contact part to prevent destructive results on the all-in-one screen during the experiment.

[0030] This vibration test fixture is an integrated aluminum alloy structure with a minimum natural frequency of 160Hz or above. The test conditions applicable to this fixture are as follows:

[0031] Sine test:

[0032] 10Hz–50Hz, 0.25mm;

[0033] 50Hz–100Hz, 2.5g;

[0034] Sine test:
