The invention discloses a device for detecting the vibration-resistant performance of a storage battery. The device comprises a tray assembly, a support and a power transmission system, and the tray assembly and the power transmission system are located on the upper portion and the lower portion of the support respectively. The four corners of the upper portion of the support are each provided with one guide shaft, the tray assembly comprises a vibrating tray, pin fixing plates, adjusting pins, guide tubes and a storage battery fixing structure, the left side and the right side of the vibrating tray are each provided with one pin fixing plate, and the adjusting pins are connected with the pin fixing plates. The four corners of the vibrating tray are each provided with one guide tube matched with the corresponding guide shaft of the support, and the storage battery fixing structure is arranged on the vibrating tray. The power transmission system comprises a motor, a transmission shaft and cams. The motor is connected with the support through the transmission shaft, and the two cams are arranged on the transmission shaft and located under the adjusting pins respectively and make contact with the adjusting pins. The device is simple in structure and convenient to operate, vibration-mode experiments under different conditions can be simulated, and the device is a relatively good detection device.
