DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-4 A waterproof performance testing device for electronic products comprises a platform 1, a test water tank 2 is arranged on the right side of the upper surface of the platform 1, a water storage tank 3 is arranged on the upper surface of the platform 1 and on the left side of the test water tank 2, a placement rack 4 is arranged on the upper part of the water storage tank 3 and fixed on the upper surface of the platform 1, a water delivery mechanism 5 is arranged on the placement rack 4, a visible cover plate 6 is arranged on the upper end horizontal cover of the test water tank 2, a fixing plate 7 is vertically fixed to the rear end of the test water tank 2, a driving mechanism 8 is connected to the front side of the fixing plate 7, a fixing rack 9 is connected to the bottom end of the driving mechanism 8, and an electronic product 11 is horizontally mounted on the fixing rack 9.

[0019] Among them, a placement groove 21 is opened at the upper end of the test water tank 2, and the visible cover 6 can be placed horizontally in the placement groove 21. A water storage chamber 22 is opened in the test water tank 2. A spray head 10 is arranged in the water storage tank 22, and the spray head 10 is connected to the water delivery mechanism 5. A drain valve 12 is arranged on one side of the test water tank 2, and the drain valve 12 is connected to the water storage chamber 22. The drain valve 12 is convenient for discharging the water in the water storage chamber 22 in time, so as to facilitate emptying the water storage chamber 22 for the next waterproof performance test.

[0020] In addition, the water delivery mechanism 5 includes a water pump 51, which is horizontally installed on the upper surface of the placement rack 4. A water suction pipe 52 is connected to one side of the water pump 51, and the water suction pipe 52 is connected to the bottom water tank 3. A water delivery pipe 53 is connected to the other side of the water pump 51. The water delivery pipe 53 extends into the water storage chamber 22 and is connected and installed with the sprinkler head 10. The water pump 51 is convenient for pumping out water in the water tank 3 and then transporting it to the sprinkler head 10 for spraying, so that the water is sprayed on the electronic product 11 to simulate the scene when it rains.

[0021] Moreover, the driving mechanism 8 includes a cylinder 81, the back of which is fixedly arranged on the front surface of the upper part of the fixing plate 7, a telescopic rod 82 is connected to the output end at the bottom of the cylinder 81, a connecting rod 83 is fixedly connected to the bottom end of the telescopic rod 82, and a fixing frame 9 is connected to the front end of the connecting rod 83. The telescopic rod 82 is driven by the cylinder 81 to drive the fixing frame 9 to move up and down, thereby moving the electronic product 11 to a specified height for waterproof testing in different scenarios.

[0022] At the same time, the fixing frame 9 includes a chassis 91, an electronic product 11 is horizontally placed on the upper end of the chassis 91, a magnetic block 92 is arranged on the upper surface of the chassis 91, and limit plates 94 are symmetrically installed on the rod bodies at the front and rear ends of the chassis 91. A rubber pad 93 is attached to the inner side wall of the limit plate 94. The limit plate 94 is fixed on the rod body of the chassis 91 by the fixing component 13. The magnetic block 92 can effectively absorb the metal shell of the electronic product 11 to play a role in supporting and fixing it.

[0023] In this embodiment, the device can be used when it is necessary to test the waterproof performance of electronic products 11 of the same batch and the same specification. First, the electronic product is placed on the fixing frame 9, and the fixing component 13 is screwed into the threaded hole on the limiting plate 94 that engages with it, and then screwed into the threaded holes on the front and rear rods of the chassis 91, so that the limiting plate 94 can be installed on the chassis 91, and then the limiting plate 94 is fixed by the fixing component 13. At the same time, it can be ensured that the front and rear limiting plates 94 can fit tightly against the electronic product 11. The provided rubber pad 93 is convenient for protecting the electronic product from scratches caused by the squeezing of the limiting plate 94.

[0024] Then the electronic product 11 is placed on the chassis 91 of the fixing frame 9, and the magnetic block 92 can effectively absorb the metal shell of the electronic product 11 to support and fix it, and then the waterproof performance test can be carried out.

[0025] First, the fixing frame 9 is moved up and down through the driving mechanism 8, and the cylinder 81 makes the telescopic rod 82 descend, and the fixing frame 9 is sent to the middle layer of the water storage chamber 22. At this time, the fixing frame 9 is just below the spray head 10, and the spray head 10 is just aimed at the electronic product 11. Then the visible cover 6 can be covered on the placement groove 21, and the test can be started. The visible cover 6 can prevent the water sprayed by the spray head 10 from splashing on the electronic product 11, and the visible window on the visible cover 6 is convenient for the operator to observe the inside.

[0026] After covering the visible cover 6, the water pump 51 can be started. The water pump 51 draws water from the water storage tank 3 filled with water, and then transports the water to the sprinkler head 10 through the water pipe 53, so that the sprinkler head 10 sprays water, and the water will continue to splash onto the electronic product 11, simulating the scene when it rains, and testing the waterproof performance of the mobile phone. After testing for a period of time, the operator can turn off the water pump 51, open the visible cover 6, and operate the electronic product 11 to see whether it operates normally, thereby judging its waterproof performance.

[0027] After simulating the rainy scene, because the test water tank 2 has been continuously sprayed and released by the sprinkler head 10, a large amount of water has been stored at the bottom of the water storage chamber 22. At this time, it is only necessary to continue to start the cylinder 81 to move the telescopic rod 82 downward, so that the fixing frame 9 and the electronic product 11 are slowly submerged in the water, so that the electronic product 11 is completely immersed in the water. If there is not enough water, the water pump 51 can be continued to be started to add water, which can simulate the scene of the electronic product 11 falling into the water. Then, the visible cover 6 can be used to timely observe whether the mobile phone in the water is operating normally, and then the driving mechanism 8 is lifted to raise the fixing frame 9 to the initial position to see whether the electronic product 11 is operating normally, thereby judging its waterproof performance and replacing the next electronic product 11 for testing.

[0028] Moreover, the drain valve 12 is convenient for timely draining the water in the water storage chamber 22, so as to empty the water storage chamber 22 for the next waterproof performance test.

[0029] In the utility model, the driving mechanism 8 is set to enable the fixing frame 9 to move up and down in the water storage chamber 22 of the test water tank 2, so that the electronic product 11 can be moved to different heights for testing in different scenes. The spray head 10 cooperates with the water delivered by the water delivery mechanism 5 to spray the electronic product 11 to simulate the water inflow in the rain scene. At the same time, the water storage chamber 22 will store water to facilitate the electronic product 11 to continue to descend and be completely immersed in the water, so as to simulate the scene of the electronic product 11 falling into the water and being soaked in water, so that the test device can realize the simulation of different scenes, making the waterproof performance test of the electronic product more comprehensive.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
