The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention.
In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application. Also, the terms "first," "second," and the like are used to distinguish between similar elements and not necessarily to describe a particular order or chronological order. It is to be understood that such terms so used are interchangeable under appropriate circumstances.
In conventional designs, the working stroke of the actuator or the rotational position of the door lock tongue is generally used as a condition for determining retraction of the trigger mechanism, but often, before that, the door is opened, and additional operations are prone to generating excessive sounds, reducing comfort of use.
It is therefore desirable to provide a top door actuator structure, as shown in fig. 1 and 2, that includes:
The first end of the ejector rod 33a is provided with a step, the compression spring 12 is fixedly arranged on the step and sleeved at the first end of the ejector rod 33a, the vertex of the first end of the ejector rod 33a is provided with the contact end 21 of the second wire, and the second end of the ejector rod 33a is fixedly connected with the driving part;
The first end of the compression spring 12 is fixed on a head 19, the second end of the compression spring 12 is fixed on the step and sleeved on the first end of the ejector rod 33a, the first end of the compression spring 12 is provided with a contact end 11 of a first wire, and the second end of the compression spring 12 is connected with the first wire 13;
When an external force acts on the head 19, the head 19 receives a force toward the jack 33a, the head 19 contacts the jack 33a at the first end vertex, and the contact end 11 of the first wire contacts the contact end 21 of the second wire at the first end vertex of the jack 33a to turn on an execution power supply to start the driving part, and the driving part drives the jack 33a to move toward and away from the driving part when the head 19 compresses the compression spring 12, when the compression spring 12 is in a natural state.
Further, the contact end 11 of the first wire, the compression spring 12 and the first wire 13 constitute a first partial circuit 10. The contact end 21 of the second wire is fixed at the vertex of the first end of the ejector rod 33a while being connected to the second wire 23, and the contact end 21 of the second wire and the second wire 23 constitute the second local circuit 20. After the first partial circuit 10 and the second partial circuit 20 are turned on, the execution power supply can be turned on.
Still further, the driving part includes a gear 32a driven by a motor, a screw 32b fixedly connected to the gear 32a, a screw nut 33b drivingly connected to the screw 32b, and a second end of the jack 33a fixedly connected to the screw nut 33 b. In one embodiment, the gear 32a is coupled to some motor-driven speed reducer structure, and mechanical rotation of the motor may drive the gear 32a to rotate.
The motor drives the gear 32a to rotate and drives the screw rod 32b to rotate in the state of switching on the execution power supply, the screw rod 32b drives the screw rod nut 33b to move far away from the gear 32a through nut transmission and drives the ejector rod 33a to move far away from the gear 32a, and the state is a mechanism ejection state which is used for ejecting the top door actuator structure so as to eject the top door actuator structure to the vehicle door and separate the top door actuator structure.
The motor drives the gear 32a to rotate and drives the screw 32b to rotate in a state of cutting off the execution power, and the screw 32b drives the screw nut 33b to move towards the gear 32a and drives the ejector rod 33a to move towards the gear 32a through nut transmission, wherein the state is a mechanism retraction state which is used for resetting the top door actuator structure so as to ensure that the subsequent door closing operation can be implemented.
Preferably, the top door actuator structure further comprises a housing 31, and the housing 31 encloses the gear 32a, the lead screw 32b, and the lead screw nut 33b. The housing 31 is further provided with an opening for expanding and contracting the jack 33a fixedly connected with the screw nut 33b.
As shown in fig. 3-5, the top door actuator structure has the following four working states when in operation:
In the first working state 100, the door is in a closed state, the top door actuator structure is in an original state, that is, the head 19 is not subjected to external force, the compression spring 12 is relaxed, the contact end 11 of the first wire is not in contact with the contact end 21 of the second wire, and the ejector rod 33a is located in an original position.
In the second working state 110, the door is in a closed state, at this time, a user initiates an instruction of opening the door, the controller notifies the door lock to be electrically unlocked, and applies an external force to the head 19, the head 19 is subjected to a force towards the ejector rod 33a, when the head 19 compresses the compression spring 12, the head 19 contacts with the vertex of the first end of the ejector rod 33a, and the contact end 11 of the first wire contacts with the contact end 21 of the second wire to switch on the execution power, at this time, the driving part starts to push the ejector rod 33a to move away from the gear 32 a.
In the third operating state 120, the door is in a closed state, the compression spring 12 is continuously compressed, the contact end 11 of the first wire is in contact with the contact end 21 of the second wire to switch on the execution power, and at this time, the driving part continuously pushes the ejector rod 33a to move away from the gear 32a until the door and the top door actuator structure are disengaged.
In the fourth operating state 130, the door is in an open state, the door and the top door actuator structure are disengaged, the external force is eliminated, the compression spring 12 is relaxed, the head 19 is far away from the vertex of the first end of the ejector rod 33a by the elastic force of the compression spring 12, and the contact end 11 of the first wire is disconnected from the contact end 21 of the second wire.
Further, after the contact end 11 of the first wire is disconnected from the contact end 21 of the second wire, the controller determines that the state of cutting off the execution power is performed at this time, and the motor drives the gear 32a to rotate and drives the screw 32b to rotate, and the screw 32b drives the screw nut 33b to move towards the gear 32a and drives the ejector rod 33a to move towards the gear 32a through nut transmission, which can be understood that the driving component drives the ejector rod 33a, the compression spring 12, the head 19, the first wire 13 and the contact end thereof, and the second wire 23 and the contact end thereof to move towards the gear 32a until the first operation state 100 is reset, thereby ensuring that the subsequent door closing operation can be performed.
In summary, in the top door actuator structure provided by the invention, the top door actuator structure is arranged to rapidly open the vehicle door, and the time when the vehicle door is opened is accurately obtained by judging the contact condition of the top door actuator structure and the vehicle door, so that the perception of a customer is improved.
