Abstract: Provided is a multi-channel actuator for driving a low-side device. The actuator includes a controller that receives a first command for driving a low-side device and outputs data representative of the first command. The actuator includes a driving circuit having a plurality of detection and driving stages. The plurality of detection and driving stages are operative to be coupled to a plurality of channels of the low-side device, respectively. The driving circuit receives the data representative of the first command and causes a detection and driving stage of the plurality of detection and driving stages to drive a respective channel of the low-side device in accordance with the first command.

Abstract: A door guardrail includes a door guardrail body having an opening; a movable baffle movably mounted on and movable relative to the door guardrail body to open or close the opening; and a locking device, arranged on the movable baffle or the door guardrail body; and wherein the locking device is capable of limiting or releasing the movement of the movable baffle relative to the door guardrail body.

Abstract: Disclosed are a connecting assembly, a door guardrail and a fence using the connecting assembly. The connecting assembly includes a first connector and a second connector, a transverse locking device and a longitudinal locking device are arranged between the first connector and the second connector, and the longitudinal locking device is capable of limiting relative movement of the first connector and the second connector in a transverse direction.

Abstract: Disclosed is a foldable pet cage, including a frame operable in unfolded and folded states. The frame includes at least two supporting rod assemblies, the supporting rod assemblies are each formed by movably connecting a vertical rod, an upper connecting rod and a lower connecting rod. All the upper connecting rods are rotatably connected with an upper connecting seat, and a first locking structure is arranged between the upper connecting seat and the upper connecting rod. All the lower connecting rods are rotatably connected with a lower connecting seat, and a second locking structure is arranged between the lower connecting seat and the lower connecting rod.

Abstract: Disclosed is door guardrail. The door guardrail includes a door guardrail body having an opening; a movable baffle movably mounted on and movable relative to the door guardrail body to open or close the opening; and a locking device, arranged on the movable baffle or the door guardrail body; and wherein the locking device is capable of limiting or releasing the movement of the movable baffle relative to the door guardrail body.

Abstract: A playpen door, including a door frame; a door body movably mounted on the door frame; and a detection assembly mounted on the door frame and the door body and configured to detect open or closed state of the door body. The door body is hinged to the door frame. A locking assembly is arranged between the door body and the door frame. The locking assembly may be opened by a switch. The detection assembly is mounted away from a position where the door body is hinged to the door frame. When the door body rotates relative to the door frame, the detection assembly may be triggered, at which time the door body may be sensed to be open. When the door body returns to the closed position again after opening, the detection assembly may be triggered, at which time the door body may be sensed to be closed.

Abstract: Disclosed is a roller-shutter-type guardrail, which includes: a shutter fixing seat provided with an insertion hole; and a shutter assembly, the roller shutter assembly including a shutter mounting seat, a rotating shaft being rotatably mounted on the roller shutter mounting seat, the rotating shaft being provided with a shutter cloth, a connecting member being arranged on a free end of the shutter cloth, and the shutter mounting seat being provided with a locking mechanism for limiting or releasing rotation of the rotating shaft.

Abstract: Disclosed is a bed guardrail, which includes a bed guardrail body, the bed guardrail body being formed by more than two base members that are hinged in sequence; and a supporting chassis, the supporting chassis being detachably connected with the bed guardrail body, and the supporting chassis being perpendicular to the bed guardrail body.

Abstract: A playpen door, including a door frame; a door body movably mounted on the door frame; and a detection assembly mounted on the door frame and the door body and configured to detect open or closed state of the door body. The door body is hinged to the door frame. A locking assembly is arranged between the door body and the door frame. The locking assembly may be opened by a switch. The detection assembly is mounted away from a position where the door body is hinged to the door frame. When the door body rotates relative to the door frame, the detection assembly may be triggered, at which time the door body may be sensed to be open. When the door body returns to the closed position again after opening, the detection assembly may be triggered, at which time the door body may be sensed to be closed.

Abstract: A playpen door, including: a door frame, a door body movably mounted on the door frame and having an open state and a closed state, and a detection assembly mounted on the door frame or the door body. The detection assembly includes a control panel, a control switch and a pressing module. The control switch is arranged on the control panel, the pressing module is configured to be movable with respect to the control switch to trigger the control switch, and the pressing module is driven to move with respect to the control switch when the door body is switched between the open state and the closed state.
