3results about How to "Improve test convenience" patented technology

The utility model relates to the field of test equipment, in particular to a portable intelligent cockpit voice interaction test device, which comprises an industrial control mainboard, a memory, a sound card, a power amplifier, a loudspeaker, a sound pickup and a sound amplification unit, when an interaction test is carried out, the industrial control mainboard inputs an interaction test digital signal stored in the memory into the sound card for analog-to-digital conversion; and the power amplifier amplifies the power of the obtained analog signal and outputs the amplified analog signal to the loudspeaker for playing, so that the voice test is performed on the intelligent cabin. When the intelligent cabin returns audio feedback, the sound pickup is used for collecting the audio feedback, the audio feedback is amplified by the sound amplification unit to obtain an amplified analog signal, and the amplified analog signal is converted into a digital signal by the sound card and stored in the memory to complete the test. The system is high in integration level, hardware needed by voice interaction testing is integrated in one system, and testing convenience is greatly improved.

The utility model discloses a kind of gas mist valve pressure resistance explosion test tool, including detachably connected fixed seat and seat cover, and branch pipe connected with fixed seat;Fixed seat is formed with the accommodating chamber of accommodating gas mist valve inside;Branch pipe has first branch part for connecting pressure gauge, second branch part for connecting external pressure-increasing equipment, and branch pipe part for connecting fixed seat between first branch part and second branch part;Valve is provided in first branch part and second branch part;The utility model can carry out pressure resistance and explosion test to gas mist valve respectively by the valve opening and closing state of two branch parts, without setting tool respectively, improve test convenience, reduce test cost.

The utility model discloses a lithium battery performance detection device in high and low temperature environments, and relates to the technical field of lithium batteries. A low-temperature testing machine is arranged at the side end of the high-temperature testing machine; a test battery is arranged in the low-temperature test machine; the side end of the high-temperature testing machine is fixedly connected with a conveying belt; the top end of the high-temperature testing machine is in sliding connection with automatic sealing glass; a tested battery is moved into the high-temperature testing machine, heat is discharged into the high-temperature testing machine through an exhaust pipe, fan blades are rotated through a motor, heat airflow is disturbed through rotation of the fan blades, hot airflow can flow in the high-temperature testing machine, the heat can make uniform contact with the tested battery, and the heat is prevented from being transmitted in the fixed direction; and then the tested battery is moved into the low-temperature testing machine to be subjected to low-temperature testing, high-temperature testing and low-temperature testing can be carried out at the same stage, and the testing convenience is improved.
