Example 1

As shown in fig. 1, the present embodiment provides an emergency lighting installation comprising an illumination lamp 1 and a conversion device consisting of a top shell 2 and a bottom shell 3. In the emergency lighting facility of the embodiment, the lighting lamp 1 is arranged under the floor 4, the top shell 2 is fixedly connected with the floor 4, the bottom shell 3 is fixed, and the floor 4 is a transparent floor. When a person passes through the device, external force is applied to the conversion device by the impact of stepping on the floor, the external force is converted into electric energy by the piezoelectric device in the conversion device, and the electric energy is transferred to the illuminating lamp 1 by the lead-out wire to work by the illuminating lamp 1. Preferably, without limiting the floor 4 to be a transparent floor, the illumination lamp 1 can be placed on the floor 4, such as the corners of the floor 4 and the wall; preferably, the lamp 1 comprises an accumulator suitable for storing the electric energy transmitted by said conversion means through the electric wires and for providing a continuous supply of energy to the lamp 1. The design mode enables the emergency lighting facility to work normally through the electric power converted by the external force applied by the escaper stepping on the floor 4 under the condition that the conventional energy supply fails, reduces the potential safety hazard, and meanwhile, the design can provide additional energy supply under the condition that the conventional energy supply does not fail, thereby being beneficial to saving energy.

Specifically, as shown in fig. 2 and 3, the bottom case 3 includes a driving case 31, a driven case 32 and a fixing case 33, an external thread is disposed on an outer side wall of the top case 2, an internal thread is disposed on an inner side wall of the driving case 31, when the conversion device is installed, the internal thread and the external thread are matched with each other to fix the top case 2 and the bottom case 3 together, the bottom case 3 includes a first hollow cavity 30, and the top case 3 is suitable for being inserted into the first hollow cavity 30 to move up and down; the top case 2 includes a second hollow chamber 21, and the first hollow chamber 30 and the second hollow chamber 2 coaxially form a damping chamber in which a spring 5 is disposed. The cross section of the internal thread and the external thread is a one-way thread, such as a triangular thread in the embodiment, which enables the threads to be disengaged when the top shell 2 and the bottom shell 3 move relatively, and the damping force is provided by the spring 5; however, when the top and bottom shells move toward each other, the threads are firmly fixed to each other and cannot be disengaged, thereby preventing the top shell 2 and the bottom shell 3 from being disengaged. The spring 5 is an elastic element widely used in the mechanical and electronic industries, the spring 5 can generate large elastic deformation when being loaded, mechanical work or kinetic energy is converted into deformation energy, and the deformation of the spring 5 disappears and returns to the original shape after being unloaded, and the deformation energy is converted into the mechanical work or the kinetic energy. When external force strikes equipment, the screw thread is tripped, the top shell 2 and the bottom shell 3 are close to each other, the spring 5 is compressed, the spring 5 applies extrusion acting force to the upper surface of the inner side of the top shell 2 and the lower surface of the inner side of the bottom shell 3, and after the external force strikes and disappears, the spring 5 can restore the original shape due to restoring force. Because top shell 2 links to each other with light 1 through connecting accessory 4, is in the stationary state, after external force impact disappears, the internal thread of initiative shell 31 and the external screw thread of top shell 2 lock again, and the extrusion effort that spring 5 applyed to the upper surface of the inboard of top shell 2 and the lower surface of the inboard of drain pan 3 can promote drain pan 3 along the screw thread rotation recovery normal position. Referring to fig. 4, in the process of returning to the original position of the bottom housing 3 by rotating along the screw thread, the driving housing 31 directly contacts the top housing 2 through the screw thread, and since the driving housing 31 and the driven housing 32 are fixed to each other by the first shaft 321 located at the bottom end of the driven housing 32, the driving housing 31 drives the driven housing 32 to move, and the fixed housing 33 is fixed. It should be noted that only when the external impact disappears and the spring 5 pushes the bottom shell 3 to rotate and recover, the driving shell 31 drives the driven shell 32 to move, and the driven shell 32 cannot be driven in the direction opposite to the recovery direction.

This embodiment cushions through spring 5 that sets up in the shock attenuation cavity between top shell 2 and shell 3, spring 5 can produce great elastic deformation when the atress, turn into mechanical power or kinetic energy and warp the ability, and the deformation of uninstallation back spring 5 disappears and the reconversion, turn into mechanical power or kinetic energy with warping the ability, consequently spring 5 can absorb vibration and impact energy, the intensity of vibration when having alleviateed equipment and having received external force and assault, turn into controllable mechanical energy with the mechanical energy of uncontrollable strong impact. In the process that the bottom shell 3 returns to the original position along the rotation of the threads, the driving shell 31 drives the driven shell 32 to move, and then the spring 6 is driven to drive the gear 7 to rotate and impact the hammer body 9, so that the hammer 91 impacts the piezoelectric structure to convert mechanical energy into electric energy, an additional power supply is provided for the equipment, and energy conservation is facilitated.
