A drive assembly, in particular for driving a flap (5), includes a hinge assembly (2), comprising a first hinge part (3) connectable to a vehicle body and a second hinge part (4) connectable to a vehicle flap (5), a joint assembly (7) comprising at least a first joint part (8) hingedly connecting said first hinge part (3) with said second hinge part (4) and a first actuator (10) for driving the second hinge part (4) to move between an opened and a closed position during a normal operation. The first actuator (10) has a first end (10a) coupleable to a vehicle body pivotally about a first pivot axis (P1) and a second end (10b). The drive assembly also includes a bearing element connected (16) to the first actuator (10) and a coupling assembly (14) for coupling the first actuator (10) to the hinge assembly (2), comprising a first coupling part (15) having a first end (15a) and a second end (15b). The first end (15a) of the first coupling part (15) is coupled to one of the second hinge part (4) and first joint part (8) pivotally about a second pivot axis (P2). The bearing element (16) of the first actuator (10) is coupled to the second end (15b) of the first coupling part (15) pivotally about a third pivot axis (P3) spaced apart from the second pivot axis (P2). The drive assembly provides a possibility to move a vehicle flap drivingly between a closed and an opened position and further provides a reliable pedestrian protection function.

An adjusting base for door closer includes a fixing member, an adjusting member, and at least one adjusting unit. The fixing member is configured to be fixed to a surface, and an upper surface of the fixing member is arranged with at least one protrusion. The adjusting member is arranged on the upper surface of the fixing member in an adjustable manner, and configured to be connected to a door closer. The adjusting member is formed with at least one adjusting hole for receiving the at least one protrusion. The at least one adjusting unit is movably arranged on the adjusting member and configured to abut against the at least one protrusion to adjust a relative position between the adjusting member and the fixing member.

The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

A retrofit module configured for use with a door closer having a pinion. The retrofit module generally includes a case, an output shaft, a motor, and a control assembly. The output shaft is rotatably mounted in the case, and is configured for rotational coupling with the pinion. The motor is mounted to the case, and is operable to rotate the output shaft in a door-opening direction. The control assembly is mounted to the case, and is configured to operate the motor to drive the output shaft in the door-opening direction in response to an actuating signal.

A backplate for a door actuator includes at least one first mounting element and a second mounting element, wherein one of the two mounting elements is formed for fastening to a mounting surface, in particular door, casing or wall, and the other mounting element is formed for receiving the door actuator. The backplate also includes, at least one connecting assembly, which in a retaining position, keeps the two mounting elements together and, in a release position, does not keep the two mounting elements together, and at least one shape memory assembly with a shape memory element made from shape memory material, wherein, upon thermal activation, the shape memory assembly moves the connecting assembly to the release position.
