Description

Technical Field

[0001] The invention relates to the technical field of automobile door lock structures, and in particular to a door lift actuator structure. Background Art

[0002] With the development of passenger car technology, especially the new wave of design brought by the increasing popularity of electric vehicles, more and more new cars use hidden handles or even handleless designs. This structure usually uses electric unlocking door locks, and requires that the door can automatically pop open after the door opening command is issued to facilitate passengers to enter.

[0003] In traditional designs, the actuator working stroke or the rotational position of the door lock tongue is usually used as the judgment condition for the retraction of the trigger mechanism. However, the car door is often opened before this, and additional operations are likely to produce unnecessary noise, reducing the comfort of use.

[0004] Therefore, it is necessary to provide a top door actuator structure, by setting the top door actuator structure to quickly open the door, and by determining the contact between the top door actuator structure and the door, the moment when the door is opened is accurately obtained, thereby improving customer perception. Summary of the invention

[0005] The purpose of the present invention is to provide a top door actuator structure, which can quickly open the door and accurately obtain the moment when the door is opened by determining the contact between the top door actuator structure and the door, thereby improving customer perception.

[0006] In order to solve the problems existing in the prior art, the present invention provides a top door actuator structure, comprising:

[0007] A push rod, wherein a step is provided at the first end of the push rod, a compression spring is fixedly mounted on the step and sleeved on the first end of the push rod, a contact end of a second wire is provided at the top of the first end of the push rod, and the second end of the push rod is fixedly connected to the driving component;

[0008] The first end of the compression spring is fixed to a head, the second end of the compression spring is fixed to the step and sleeved on the first end of the push rod, the first end of the compression spring is provided with a contact end of a first wire, and the second end of the compression spring is connected to the first wire;

[0009] When the compression spring is in a natural state, the head is not in contact with the top point of the first end of the push rod; when an external force acts on the head and the head compresses the compression spring, the head is in contact with the top point of the first end of the push rod, and the contact end of the first wire is in contact with the contact end of the second wire located at the top point of the first end of the push rod, so as to turn on the execution power supply to start the driving component, and the driving component drives the push rod to move away from the driving component.

[0010] Optionally, in the top door actuator structure, the driving component includes:

[0011] A gear driven by a motor, a lead screw fixedly connected to the gear, a lead screw nut drivingly connected to the lead screw, and the lead screw nut fixedly connected to the second end of the push rod;

[0012] When the execution power is turned on, the motor drives the gear to rotate, and drives the lead screw to rotate; the lead screw drives the lead screw nut to move away from the gear through the nut, and drives the push rod to move away from the gear;

[0013] When the execution power supply is cut off, the motor drives the gear to rotate and drives the lead screw to rotate; the lead screw is driven by the nut to make the lead screw nut move toward the gear and drives the push rod to move toward the gear.

[0014] Optionally, in the top door actuator structure, the top door actuator structure further includes a shell, and the shell encloses the gear, the lead screw and the lead screw nut.

[0015] Optionally, in the door lift actuator structure, the shell also reserves an opening to extend and retract the lift rod fixedly connected to the lead screw nut.

[0016] Optionally, in the top door actuator structure, the contact end of the second wire is fixed to the top point of the first end of the top rod and connected to the second wire at the same time.

[0017] Optionally, in the top door actuator structure, when external force acts on the head, the contact end of the first wire contacts the contact end of the second wire, and after the execution power is turned on, the driving component continues to push the top rod to move away from the gear until the vehicle door and the top door actuator structure are disengaged.

[0018] Optionally, in the top door actuator structure, after the vehicle door and the top door actuator structure are detached, the external force disappears, and the elastic force of the compressed spring on the head moves away from the top point of the first end of the top rod, so that the contact end of the first wire is disconnected from the contact end of the second wire.

[0019] Optionally, in the top door actuator structure, after the contact end of the first wire is disconnected from the contact end of the second wire, the driving component drives the top rod, the compression spring, the head, the first wire and its contact end, and the second wire and its contact end to move toward the gear until they are reset.

[0020] In the top door actuator structure provided by the present invention, the top door actuator structure is provided to quickly open the vehicle door, and the moment when the vehicle door is opened is accurately obtained by determining the contact condition between the top door actuator structure and the vehicle door, thereby improving customer perception.

[0026] The specific implementation of the present invention will be described in more detail below in conjunction with the schematic diagram. The advantages and features of the present invention will become clearer based on the following description. It should be noted that the drawings are all in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.

[0027] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are used to distinguish between similar elements, and are not necessarily used to describe a specific order or time sequence. It should be understood that these terms used in this way are interchangeable where appropriate.

[0028] In traditional designs, the actuator working stroke or the rotational position of the door lock tongue is usually used as the judgment condition for the retraction of the trigger mechanism. However, the car door is often opened before this, and additional operations are likely to produce unnecessary noise, reducing the comfort of use.

[0029] Therefore, it is necessary to provide a top door actuator structure, such as Figure 1 and 2 As shown, the top door actuator structure includes:

[0030] A push rod 33a, wherein a step is provided at the first end of the push rod 33a, a compression spring 12 is fixedly mounted on the step and sleeved on the first end of the push rod 33a, a contact end 21 of a second wire is provided at the top of the first end of the push rod 33a, and a second end of the push rod 33a is fixedly connected to a driving component;

[0031] The first end of the compression spring 12 is fixed to a head 19, the second end of the compression spring 12 is fixed to the step and sleeved on the first end of the top rod 33a, the first end of the compression spring 12 is provided with a contact end 11 of the first wire, and the second end of the compression spring 12 is connected to the first wire 13;

[0032] When the compression spring 12 is in a natural state, the head 19 is not in contact with the first end vertex of the push rod 33a; when an external force acts on the head 19, the head 19 is subjected to a force toward the push rod 33a. When the head 19 compresses the compression spring 12, the head 19 contacts the first end vertex of the push rod 33a, and the contact end 11 of the first wire contacts the contact end 21 of the second wire located at the first end vertex of the push rod 33a, so as to turn on the execution power supply to start the driving component, and the driving component drives the push rod 33a to move away from the driving component.

[0033] Furthermore, 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 top rod 33a and connected to the second wire 23. The contact end 21 of the second wire and the second wire 23 constitute a second partial circuit 20. After the first partial circuit 10 and the second partial circuit 20 are connected, the execution power supply can be turned on.

[0034] Furthermore, the driving component includes: a gear 32a driven by a motor, a lead screw 32b fixedly connected to the gear 32a, a lead screw nut 33b transmission-connected to the lead screw 32b, and the lead screw nut 33b is fixedly connected to the second end of the push rod 33a. In one embodiment, the gear 32a is connected to a reducer structure driven by a motor, and the mechanical rotation of the motor can drive the gear 32a to rotate.

[0035] When the execution power is turned on, the motor drives the gear 32a to rotate, and drives the lead screw 32b to rotate; the lead screw 32b drives the lead screw nut 33b to move away from the gear 32a through the nut, and drives the push rod 33a to move away from the gear 32a. This state is the mechanism ejection state, and the mechanism ejection state is used to eject the door ejection actuator structure, thereby ejecting the vehicle door and the door ejection actuator structure.

[0036] When the execution power is cut off, the motor drives the gear 32a to rotate, and drives the lead screw 32b to rotate; the lead screw 32b drives the lead screw nut 33b toward the gear 32a through the nut, and drives the push rod 33a to move toward the gear 32a. This state is the mechanism retracted state, and the mechanism retracted state is used to reset the top door actuator structure, thereby ensuring that the subsequent door closing operation can be implemented.

[0037] Preferably, the door lift actuator structure further comprises a housing 31, wherein the housing 31 encloses the gear 32a, the lead screw 32b and the lead screw nut 33b. The housing 31 also has an opening reserved for retracting the lift rod 33a fixedly connected to the lead screw nut 33b.

[0038] like Figure 3-5 As shown, the top door actuator structure has the following four working states when working:

[0039] In the first working state 100, the vehicle door is in a closed state, and the door lift 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 lift rod 33a is in an original position.

[0040] In the second working state 110, the vehicle door is in a closed state. At this time, the user initiates a command to open the door, and the controller notifies the door lock to unlock electrically and applies an external force to the head 19. The head 19 is subjected to a force toward the push rod 33a. When the head 19 compresses the compression spring 12, the head 19 contacts the top point of the first end of the push rod 33a, and the contact end 11 of the first wire contacts the contact end 21 of the second wire to turn on the execution power supply. At this time, the driving component starts to push the push rod 33a to move away from the gear 32a.

[0041] In the third working state 120, the vehicle door is in a closed state, the compression spring 12 is continuously compressed, the contact end 11 of the first wire contacts the contact end 21 of the second wire to turn on the execution power supply, and the driving component continuously pushes the top rod 33a to move away from the gear 32a until the vehicle door and the top door actuator structure are disengaged.

[0042] In the fourth working state 130, the vehicle door is in an open state, the vehicle door and the top door actuator structure are separated, the external force disappears, the compression spring 12 relaxes, and the head 19 is moved away from the top point of the first end of the top rod 33a by the elastic force of the compression spring 12, so that the contact end 11 of the first wire is disconnected from the contact end 21 of the second wire.

[0043] 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 execution power is cut off at this time. At this time, the motor drives the gear 32a to rotate, and drives the screw 32b to rotate. The screw 32b drives the screw nut 33b toward the gear 32a through the nut, and drives the push rod 33a to move toward the gear 32a. It can be understood that the driving component drives the push rod 33a, the compression spring 12, the head 19, the first wire 13 and its contact end, and the second wire 23 and its contact end toward the gear 32a until they are reset to the first working state 100, thereby ensuring that the subsequent door closing operation can be implemented.

[0044] In summary, in the top door actuator structure provided by the present invention, the top door actuator structure is provided to quickly open the vehicle door, and the moment when the vehicle door is opened is accurately obtained by determining the contact condition between the top door actuator structure and the vehicle door, thereby improving customer perception.
