Abstract: A device for locking a vehicle and for preventing the vehicle from moving down a hill includes a housing secured to the vehicle and a beam rotatably secured in the housing. A casing is secured on top of the beam and a ball is received in the casing and has a tendency to move downward to the bottom of the casing for allowing the ball to maintaining the beam at a position perpendicular to the supporting ground. A ratchet mechanism may stop the wheels of the vehicle when the beam is tilted relative to the housing and when the housing is tilted relative to the supporting ground.

Abstract: A method for docking a robot at a charging station includes the following steps: the charging station outputs a first transmitting signal and a second transmitting signal, wherein an overlapping zone and two non-overlapping zones are formed within the signal transmission range of the first and second transmitting signals, and a blank zone forms within a predetermined distance. When the robot needs to move to the charging station, the robot detects its entry into the overlapping zone or one of the two non-overlapping zones, and the robot moves in the direction of the charging station by alternately moving in and out between the overlapping zone and one of the two non-overlapping zones until the robot moves to the blank zone, then the robot either moves directly towards the charging station, or rotates and then moves backwardly towards the charging station, thereby allowing the robot to dock at the charging station.

Abstract: A robot trapping detecting device, mainly uses a shaft body to drive a convex body to rotate, and a convex portion is disposed around the convex body, so when a binding surface of a binding body is touched to the convex body and the convex body is rotated to the disposing position of the convex portion, the binding body is driven upward, and then, when the convex body is rotated to a position other than the disposing position of the convex portion, the binding body is driven downward, so that a sensed body disposed on a linking component is driven up and down by the linking component, and a sensing body senses a displacement change of the sensed body to determine whether a robot has stopped moving.

Abstract: The invention provides an air purifier with independent duel channel, which has separate first channel portion and second channel portion, wherein the first channel portion is used to filter particulate matters in the air and the second channel portion is used to purify the air. The invention mainly separates the channels and processes of the filtered air and the purified air, and more matches the selection of specific suction fan and intake fan so as to meet the different flow velocities required for air filtration and purification respectively, thereby achieving the optimal air filtration and purification effects, and improving the ineffective problem caused by the simultaneous filtration and purification of the air in the same channel of the existing air purifier.

Abstract: The present invention provides a sensing device with a conical reflector for making a two-dimensional optical radar that mainly diffuses a light source using a diffusing element to form a diffused light, and directs the light source onto a reflection surface of a reflective element, after the diffused light is reflected to a reflector through the reflection surface, the reflector then reflects the diffused light to form a reflected light, and reflects the reflected light onto the reflection surface in order that the reflected light is reflected onto an optical lens through the reflection surface, and finally, the reflected light is directed onto a sensing module through the optical lens, and the reflected light is received through the sensing module; thereby achieving the effects of omnidirectional real-time scanning, one-time detection of 360-degree environmental characteristic points, and accurately and stably providing relative positions between each characteristic point and a robot.

Abstract: The present invention is a hair dryer deflector, which comprises a power unit and an airflow generating unit. The airflow generating unit is connected to one side of the power unit, a plurality of perforations is disposed at the positions of the airflow generating unit relative to the power unit. The airflow generating unit is driven by the power unit to rotate to generate airflow, and the airflow flows through each of the perforations to flow toward the power unit and toward an air outlet of the hair dryer.

Abstract: The present invention discloses an obstacle-adaptive mechanism of a moving device, which uses a driving wheel, a driving gear, a passive wheel, a passive gear and an intermediate gear as a transmission mechanism, wherein the driving gear is connected to one side of the driving wheel, the passive gear is connected to one side of the passive wheel, the intermediate gear is disposed between the driving gear and the passive gear to keep the driving wheel and the passive wheel rotating in the same direction to help crossing an obstacle, thereby preventing the obstacle-adaptive mechanism from being stuck by the obstacle and allowing the obstacle-adaptive mechanism to successfully crossing the obstacle. Therefore, the obstacle-adaptive mechanism of the moving device can provide the ability for crossing obstacles.
