Abstract

The embodiments of the present utility model relate to a guide rail structure and an electronic device assembly. The guide rail structure comprises a guide rail and an abutting member, wherein the guide rail is provided with an insertion slot for accommodating a pen clip of an electronic pen, and a stop surface is formed in the insertion slot and is configured, when the pen clip is inserted into the insertion slot, to be in limiting fit with the side of the pen clip facing away from the slot bottom of the insertion slot, so as to limit movement of the pen clip in the direction away from the slot bottom of the insertion slot; such an arrangement can solve the problem of the pen clip easily separating from the inside of the insertion slot, thereby ensuring reliable fixation of the electronic pen. Meanwhile, one end of the abutting member being at least partially located in the insertion slot and abutting against the pen clip for limitation can reduce damage due to friction between the pen clip and an inner wall of the insertion slot, and can provide further fixation for the pen clip, thereby preventing the pen clip from wobbling back and forth in the direction from the slot bottom to the slot opening of the insertion slot.

Abstract

The present invention relates to a cholesteric liquid crystal display, and more particularly relates to a dual-light dual-state cholesteric liquid crystal display using a front-light system and a backlight system, wherein a front-light area corresponds to a reflective pixel area of a TFT storage capacitor, and a backlight area corresponds to a conventional transparent pixel area. In the present invention, a mirror-surface effect of a storage capacitor in an active matrix and a polarization-depolarization effect of cholesteric liquid crystals are used to change a storage capacitor area into an effective display area, thereby effectively expanding the total display area of a liquid crystal display. Therefore, the liquid crystal display not only can be used in indoor ambient light conditions with an excellent color gamut, but can also be used in an outdoor sunlight readable application.

Abstract

A quadruped robot, comprising a body (5), a head (3), leg mechanisms and foot mechanisms (8). The head (3) is arranged at the front part of the body (5); the leg mechanisms at least comprise front leg mechanisms (1) close to the head (3) and rear leg mechanisms (2) far away from the head, the front leg mechanisms (1) and the rear leg mechanisms (2) being separately and rotatably connected to the body (5); each foot mechanism (8) is rotatably connected to a leg mechanism, a limiting structure (9) being formed between the foot mechanism (8) and the leg mechanism, and the limiting structure (9) being used for restricting rotation of the foot mechanism (8). Upward supporting force applied to the foot mechanisms (8) by the ground can be transmitted to the leg mechanisms, and thus the leg mechanisms can share the upward supporting force, so that the foot mechanisms (8) do not need to bear all the supporting force applied by the ground, and further the leg mechanisms can be in contact with the ground without provision of a large rotational torque, thereby reducing requirements for the rotational torque of the foot mechanisms (8).
