The invention discloses a device for detecting an automotive pedestrian voice alarming device circuit. The device comprises a box body, a test needle bed (12), a first air cylinder (14) and a tested device. A first through groove (11) is formed in a top board of the box body, the test needle bed (12) is arranged below the first through groove (11), and a measuring needle (9) is arranged on the test needle bed (12) and electrically connected with the tested device. A piston rod of the first air cylinder (14) is fixedly connected with the test needle bed (12). The tested device is arranged on the top board, the piston rod of the first air cylinder (14) extends out to drive the test needle bed (12) to move upwards and make the measuring needle (9) in contact with the test point of the tested device. According to the device for detecting the automotive pedestrian voice alarming device circuit, the requirement for circuit detection in mass production and manufacturing of automotive pedestrian voice alarming devices can be met, cost is low, the structure is simple, operation is easy, and maintaining is convenient.
Description
technical field [0001] The invention relates to the technical field of testing equipment, in particular to a device for testing a circuit of a vehicle-used pedestrian sound warning device. Background technique [0002] Hybrid cars or electric drive vehicles are quiet when driving, and when electric cars or hybrid cars running in pure electric mode pass by pedestrians at low speeds, pedestrians can hardly notice it. Therefore, there are certain potential safety hazards in the running process of the electric-driven vehicle alone. Especially for the blind (when the blind walks on the road, they rely entirely on hearing to judge whether there is a vehicle), an electric drive vehicle that is too quiet is extremely dangerous. Even for normal people, the silent passing of a vehicle or parked behind it can cause a certain degree of shock. The vehicle pedestrian sound warning device or system is used to remind pedestrians with voice or voice that there is a vehicle approaching when...
