Problems solved by technology

Obviously, this kind of manual operation method is more difficult to grasp the height and direction of the impact ball falling, resulting in low accuracy, and the free-falling impact ball is also easy to fall and lose from the object to be tested due to lack of protective measures, or it may be smashed. Injury testers, etc., low safety factor

Embodiment Construction

[0011] see figure 1 , figure 2 and image 3 , the impact testing device 100 of the preferred embodiment of the present invention is used to test the impact resistance of the object 200 to be tested. The impact testing device 100 includes a main body 10 , an air pump 30 , a transmission member 50 and an impact ball 70 . The air pump 30 and the transmission member 50 are respectively installed at opposite ends of the main body 10 and communicated with each other through the main body 10 . The impact ball 70 is disposed at the end of the transmission member 50 . Holding the main body 10 and aiming the impact ball 70 at the test point of the object to be tested 200, the air pump 30 drives the transmission member 50 to drive the impact ball 70 to impact the test point of the object to be tested 200 with a preset force, for impact resistance testing.

[0012] The main body 10 includes an air cavity 11 opened through the opposite ends of the main body 10, and the openings (not s...

Abstract

The invention relates to an impact testing device which is used for testing the impact resistance of an object to be tested. The impact testing device comprises a main body, a pneumatic pump, a transmission piece and an impact ball, wherein the pneumatic pump and the transmission piece are arranged on the main body respectively, and communicated through the main body; the transmission piece comprises a butted tube and a fixed column arranged inside the butted tube in a sliding manner; the transmission piece is communicated with the main body through the butted tube; the impact ball is fixed through the fixed column; the pneumatic pump enables air pressure inside the main body to be of a preset air pressure value; and the fixed column is driven to drive the impact ball to impact a test point of the object to be tested by using a preset impact force corresponding to the preset air pressure value through the air pressure inside the main body so as to perform an impact performance test.

Description

technical field [0001] The invention relates to a testing device for electronic products, in particular to an impact testing device for testing the impact resistance of electronic products. Background technique [0002] Small consumer electronic products such as mobile phones, digital cameras, MP3 players, and personal digital assistants (PDAs) generally need to undergo drop tests to test the impact resistance of these electronic products. The drop test method is generally to place the item to be tested at a predetermined position, manually operate the impact ball to drop freely from a preset height to impact the item to be tested, and detect the impact resistance of the item to be tested through the damage status of the item to be tested. Obviously, this kind of manual operation method is more difficult to grasp the height and direction of the impact ball falling, resulting in low accuracy, and the free-falling impact ball is also easy to fall and lose from the object to be...
