The invention discloses a self-locking door holder which comprises a main body, a sliding block, clamping jaws, a guiding groove, a spring, a steel hook, fixing buckles, a limiting groove, a limiting block and a covering plate tongue piece. The self-locking door holder is simple in structure, small in size and powerful in function, so that the mounting is convenient and the structural design of an application product is not affected. Meanwhile, a covering plate of the application product can be locked or unlocked as long as the covering plate is pressed in the using process, and thus the operation can be simplified.

The present invention relates to an eye protection method and system for an intelligent device. The method comprises: after receiving an eye protection level setting instruction, calling an eye protection level setting method, and passing an eye protection intensity level corresponding to the eye protection level setting instruction to a kernel space; and the kernel space receiving the eye protection intensity level, and writing a display parameter corresponding to the eye protection intensity level into a display hardware unit of the intelligent device, wherein the display parameter comprises a Blu-ray control parameter. According to the eye protection method and system for the intelligent device, disclosed by the present invention, the proportion of blue light in light rays emitted from a display is reduced by modifying the display parameter of the display hardware unit (a display content reprocessing unit in a display driver chip or a processor), so that an eye protection effect is realized without investment of hardware devices and influences on the structural design and overall aesthetic property of the intelligent device, thereby the method and the system having a very high practical application value.

The invention discloses a dynamic adjustable filter based on a defective refractive index laminar periodic structure. The dynamic adjustable filter comprises a laminar periodic structure modulated by periodic refractive index and a sound source; the sound source is positioned at one end of the laminar periodic structure which is provided with semiwave defect and is modulated by periodic refractive index and keeps stable, rigid and low-acoustic impedance contact with the structure. The dynamic adjustable filter is characterized in that sound wave with certain frequency and strength is conducted to the defective laminar periodic structure modulated by periodic refractive index in a different mode; through the change of strength of sound wave, defect-mode wavelength transmitted in the laminar periodic structure is modulated; and through the change of sound wavelength, the output effect of single wavelength-multiwavelength is reached. The dynamic adjustable filter has novel design, feasible preparation and wide application prospect in the field of optical communication and sensing.

The invention discloses a chassis dynamometer motor base with torque detection and radial cooling functions. The chassis dynamometer motor base comprises a motor base main body; a vertical detection platform and a horizontal detection platform which are fixedly connected with an outer wall reinforcing mechanism are respectively arranged in the middle of the outer wall of the motor base main body;the chassis dynamometer motor base further comprises a first air inlet mechanism, a second air inlet mechanism, a wiring port and a grounding point; and the inner wall of the motor base main body isprovided with a reticular reinforcing structure which is formed by fixedly connecting a first end plate, a second end plate, a reinforcing rib plate and internal axial reinforcing ribs in a crossed manner. According to the invention, by arranging the inner and outer reinforcing ribs, the structural strength is improved; a detection platform is directly reinforced; the weights of the external reinforcing ribs and the internal reinforcing ribs are far less than the weight of the thickened motor base main body due to the same effect; ventilation grooves are formed in part of the internal axial reinforcing ribs, so that the heat dissipation performance is improved; cooling is facilitated through cooperation of the first air inlet device, the second air inlet device and the gap between the reinforcing rib plate and the motor base main body; and the overall power density of the motor is greatly improved.

The invention provides a shaver and relates to the technical field of shaving tools. The shaver comprises a head cover, a knife rest and a shaver body, wherein the knife rest is used for being fixed in the head cover, the knife rest is provided with a first magnetic suction piece, the shaver body is provided with a second magnetic suction piece, and the head cover can be assembled on the shaver body through magnetic suction between the first magnetic suction piece and the second magnetic suction piece. According to the shaver, the head cover is assembled on the shaver body through the magneticattraction force between the first magnetic suction piece on the knife rest and the second magnetic suction piece of the shaver body. The shaver has less restriction on the structural design of the head cover.
