A vehicle tailgate assembly includes a tailgate and a switch assembly operably connected to the tailgate. The switch assembly includes a switch structured to be actuatable by application of a load exceeding a predetermined threshold to the tailgate. The switch assembly is operably connected to a tailgate automatic opening/closing mechanism such that actuation of the switch controls operation of the mechanism to prevent execution of a command to automatically open the tailgate when the tailgate is in a fully closed condition.

A rotary actuator assembly, a household appliance having same and a control method therefor. The rotary actuator assembly comprises an object to be rotated and a rotary actuator configured to match said object. The rotary actuator comprises an output shaft and a driving mechanism for driving the output shaft to rotate. Said object is provided with a shaft hole matching the output shaft. The output shaft and the shaft hole of said object are internally provided with a driving structure and a butt joint structure matching each other in the circumferential direction. A resisting surface and a butt joint surface for pushing said object to move during the rotation of the output shaft are formed between the driving structure and the butt joint structure. A rotation space for manual operation of said object is formed between the driving structure and the butt joint structure.

The present disclosure provides an automatic switching device and a refrigeration device. The automatic switching device comprises: an ejection structure, comprising a transmission gear and a rack matching the transmission gear in transmission; a driving device, connected to the transmission gear and used for driving the transmission gear to rotate, so as to drive the rack to extend forwards to open a door body or retract backwards to close the door body; and an auxiliary control device comprising an inductor arranged on the rack, a first induction switch and a second induction switch.

Systems of an electrical vehicle and the operations thereof are provided. A powered accessory port may be utilized to selectively reveal/conceal an interior portion, such as charging connection when the powered accessory port is disposed on the exterior of a vehicle, or a user device connection, such as when the powered accessory port is disposed in the interior of the vehicle. The powered accessory port, when energized, provides a rotational force that is partially translated into a longitudinal force such that the single rotational force provides both a lifting (or lowering) motion as well as a rotational motion.

An escape system for a sinking car and an optoelectronic component thereof are disclosed. The optoelectronic component includes a housing and an optoelectronic module. The escape system for a sinking car includes an optoelectronic component and a motherboard. A lighting unit of the escape system for a sinking car and an optoelectronic component thereof is installed on a car to emit light. After the car fell into water, by the characteristic that when light passes through a medium, the attenuation in light energy can be detected effectively because light is absorbed by that medium (such as liquid), the car sinking signal can be received and transmitted quickly, thereby actually taking the opportunities of rescue to reduce casualties.

The present invention relates to a door operator with an abnormal voltage protection function and a method for abnormal voltage protection of a door operator. According to the present invention, before a door operator motor is electrically energized by an external power source, a controller determines whether the external power source meets the rated voltage of the door operator. In the case that the external power source meets the rated voltage, the controller activates the door operator motor; in the case that the external power source does not meet the rated voltage, the door operator motor is deactivated, and the controller issues a warning.

Door operator (10) for an overhead door system (400), said door operator (10) being configured to move a door (401) of said door system (400), comprising: a first electric motor (100), a second electric motor (200), a planetary gearing (300), a control unit (11) configured to control the first (100) and second electric motor (200), and wherein the first electric motor (100) is connected to a first planetary gearing input shaft (301) and the second electric motor (200) is connected to a second planetary gearing input shaft (302), and wherein a planetary gearing output shaft (303) is associated with a shaft (402) for movement of the door (401).

Access control for an autonomous vehicle through a door in a doorway. A magnet is attached to the autonomous vehicle and a magnetometer is located some distance from the doorway. The magnetometer outputs a magnetometer signal in response to detecting the magnet, which causes the transmitter to transmit a detection signal. A doorway device is fixed about the doorway, and includes a receiver, and a locking mechanism with a locking pin. The doorway device retracts the pin to unlock the door for a predetermined period of time in response to receipt of the detection signal, and extents the pin to lock the door after the predetermined period of time ends.

A ground wire guidance system for guiding a robotic vehicle through a doorway in a barrier. The system includes a ground wire loop arranged to pass though the doorway in two directions. Plural wires are switched as the loop passes through the doorway such that the pairs of wires conducting are spaced apart, or shielded, such that the robotic vehicle can reliably navigate through a relatively narrow doorway, while one of the wires passes through a central portion of the doorway.

Systems of an electrical vehicle and the operations thereof are provided. A powered accessory port may be utilized to selectively reveal/conceal an interior portion, such as charging connection when the powered accessory port is disposed on the exterior of a vehicle, or a user device connection, such as when the powered accessory port is disposed in the interior of the vehicle. The powered accessory port, when energized, provides a rotational force that is partially translated into a longitudinal force such that the single rotational force provides both a lifting (or lowering) motion as well as a rotational motion.
