This utility model discloses a tablet computer protective case, specifically relating to the field of electronic product protective case technology. It includes: a protective case; a support plate located on one side of a base, with one end extending towards the center of the protective case and the other end near the top of the protective case; the support plate being a rectangular or polygonal structure; and a damping hinge, one end of which is connected to the base and the other end connected to the support plate. This utility model, by providing a support plate rotatably connected to the case, allows the case to be horizontally or vertically supported when unfolded, facilitating user operations such as watching videos. Furthermore, the damping hinge provides a damping effect when the support plate rotates, thereby increasing the stability of the entire protective case during use.

The shell is used for accommodating and supporting the camera module, the lighting module and the network module; the camera module is electrically connected with the power supply module and is used for shooting an image of the replacement part; the illumination module is electrically connected with the power supply module and is used for emitting visible light, and the visible light illuminates the image of the dressing change part; the lighting module comprises a lamp bead emitting visible light; the network module is electrically connected with the power supply module, is in electrical signal connection with the camera module, and is used for transmitting images shot by the camera module to a mobile phone or a computer.

This invention relates to a vibration damper for suppressing vibrations generated during rotor system operation. Specifically, it is a combined bending-torsional vibration damper for rotor systems. It comprises a first rotor, an inner torsional damping structure, rolling bearings, an outer bending damping structure, a circular support, and a second rotor. The inner torsional damping structure is positioned above the first and second rotors, within the rolling bearings, and suppresses torsional vibrations generated during rotor system operation. The outer bending damping structure is positioned above the rolling bearings, within the circular support, and suppresses bending vibrations generated during rotor system operation. Rubber rings are incorporated within both the inner and outer torsional damping structures. These rubber rings reduce noise generated during rotor system operation and also provide some vibration damping. This invention suppresses both torsional and bending vibrations generated during rotor system operation, increasing the stability and service life of the rotor system.
