[0005] The safety panel is connected to the opening of the box body through the cooperation of the buckle and the card holder. When the electromagnetic adsorption device is working, the buckle and the card holder cannot be separated, and the safety panel cannot be opened; the acceleration sensor is arranged on the inner side of the safety panel to extract one or more combinations of the number of knocks, knocking intensity or knocking frequency of the safety panel. The acceleration sensor transmits the knocking signal to the controller, and the controller compares the knocking signal with the preset signal. When the knocking signal matches the preset signal, the electromagnetic adsorption device is powered off, which facilitates the separation of the buckle and the card holder to open the safety panel and use the driver box to perform special operations on the elevator; in order to prevent children or other unrelated personnel from accidentally knocking on the opening signal, resulting in erroneous operation of the safety panel opening, when the electromagnetic adsorption device is powered off, the buckle and the card holder will not automatically separate and pop out, which increases the confidentiality of the opening of the driver box; the separation of the buckle and the card holder requires the hand to apply a certain external force to the safety panel.
[0006] Furthermore, the electromagnetic adsorption device includes a metal block and an electromagnet, wherein the metal block is arranged on the buckle, and the electromagnet is arranged on the card holder, and the metal block and the electromagnet fit together when the buckle and the card holder are engaged. When the controller receives a correct knocking signal transmitted by the acceleration sensor, it controls the electromagnet to cut off the power and lose the magnetic force, thereby facilitating the separation of the buckle and the card holder.
[0007] Furthermore, a reset module is provided in the box body, and a power supply for powering the acceleration sensor, the reset module and the electromagnet is also provided in the box body, and the reset module is electrically connected to the controller. The reset module is used to reset the preset signal about the knocking combination and erase the preset signal previously set and saved.
[0008] Furthermore, the safety panel is provided with a handle for facilitating opening the safety panel.
[0009] Furthermore, the acceleration sensor is a vibration sensor.
[0010] The beneficial effects of the utility model are as follows: a keyless elevator driver box provided by the utility model adopts an acceleration sensor to extract a knocking signal on a safety panel and transmits the knocking signal to a controller, the controller compares the knocking signal with a preset signal, and when the signal matches, the electromagnetic adsorption device is powered off, so that maintenance personnel can open the safety panel to perform special operations on the elevator conveniently, without the need to wear a key, thus avoiding the inability to open the driver box in time due to the loss of the key; the setting of the buckle and the card seat can prevent children or other unrelated personnel from accidentally knocking on the opening signal, resulting in an erroneous operation of opening the safety panel, and when the electromagnetic adsorption device is powered off, the buckle and the card seat will not automatically separate and pop out, which increases the confidentiality of the opening of the driver box.
