The specific operation of the circuit is that after the circuit is energized, the contacts of the contactor 760 are engaged in a normally closed state, i.e. the energized port 400 is in an energized state, and the tested electronic product is energized. Master timer 710 sets a time of 4 hours, sub-control timer 720 sets a time of 2 hours, cycle timer 730 sets 10 seconds on and 10 seconds off, and counter 740 sets 180 times. The master control timer 710 and the sub-control timer 720 start to count time, the first indicator 780 used for indicating the state is turned on red, after 2 hours of operation, the 6 th pin and the 8 th pin of the sub-control timer 720 are automatically closed, then the cycle timer 730 and the counter 740 start to operate simultaneously, the cycle timer 730 works in a set program cycle of 10 seconds on and 10 seconds off and controls the first relay 750 to conduct cycle on-off, on one hand, the first relay is used for controlling the on-off of the contact of the contactor 760 and controlling the on-off of the main electric fire wires L1, L2 and L3, so that the aim of simulating impact aging (namely, the cycle work of 10S and 10S of power-on and power-off of an electronic product) is achieved; on the other hand, the continuous closing and opening of the first relay contact triggers the counter 740 to count. After the cumulative count of the counter 740 reaches the set 18O times, the counter 740 immediately triggers "REST" (reset) signals of the 1 st pin and the 3 rd pin of the sub-control timer 720, the 6 th pin and the 8 th pin of the sub-control timer 720 are disconnected, the 5 th pin and the 8 th pin of the sub-control timer 720 are disconnected and closed, the corresponding cycle timer 730 and the counter 740 stop working, and the simulated impact aging stage is ended. Immediately after the electronic product is fully in a normal (always powered on) aging state, after 1 hour, the 5 th pin and the 8 th pin of the master control timer 710 are disconnected, the 6 th pin and the 8 th pin of the master control timer 710 are closed, the second relay works, the second indicator 790 in the aging state can be lightened to be green, and then the sub-control timer 720, the circulation timer 730 and the counter 740 simultaneously stop working due to the loss of power supply. The entire 4-hour total aging process from 2 hours of steady state aging to 180 impact aging to 1 hour of steady state aging to automatic power down is thus automatically completed. In addition, the timing time and the counting times can be set according to the actual process requirements of the product.
The intelligent timing and counting control circuit 700 is used for automatically controlling the aging test process, the whole aging test process is realized through one-time switch starting, and the operation of manually stirring the control switch according to the set time is not needed in the switch impact process, so that the efficiency is improved, the labor intensity is reduced, and the electricity safety is improved.
As shown in fig. 1, the power connector 800 of the intelligent aging test vehicle is a five-core explosion-proof male and female plug, and the five-core explosion-proof male and female plug is electrically connected with an external main power network in response to the intelligent timing and counting control circuit 700.
The four feet of the bracket body 100 are respectively and fixedly provided with a universal band brake mute wheel 900, and the universal band brake mute wheel 900 provides the bracket body 100 with the functions of supporting, moving and braking fixation.
For more electronic products to be mounted at a time, the bracket body 100 is provided with a plurality of layers of square frames 110, and the corresponding power-on ports 400 and port protection trays 500 are provided with a plurality of layers, which are three layers in the embodiment in consideration of the operation height of the human body.
In summary, the aging test vehicle for electronic products provided by the invention can be directly placed on the aging test vehicle after the products are produced, the products are electrically connected with the power-on ports, and the aging test vehicle is directly powered on to perform aging test by carrying the intelligent timing counting control circuit in the main control circuit control box after being pushed to the aging test area.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
