Description

Technical Field

[0001] The invention belongs to the technical field of vehicle components, and in particular relates to a hidden door handle assembly and a vehicle. Background Art

[0002] The door handle is an important component of the door. It not only has the functions of unlocking and opening the door, but also directly affects the appearance of the door. Door handles are mainly divided into fixed pull-out handles, flip-up door handles and hidden door handles. Among them, hidden door handles are increasingly used in vehicles due to their exquisite appearance, low wind resistance, and no damage to the side shape.

[0003] Common hidden door handles are mainly of the swing-open type and the push-open type. Both types of handles will protrude from the door panel after opening, which can easily cause the handle to be damaged. In addition, in a low temperature environment, if the handle is frozen, the movement of the handle outward will be restricted, making it inconvenient to use the handle and affecting the user experience. Summary of the invention

[0004] The embodiments of the present invention provide a hidden door handle assembly and a vehicle, aiming to solve the problem that the existing hidden door handles are easily bumped and difficult to open after the handles are frozen.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, a hidden door handle assembly is provided, comprising:

[0007] A box-shaped base structure, wherein an outer opening is formed on the outer side of the base structure, and a clearance groove is formed inside the base structure and is located on one side of the outer opening;

[0008] An unlocking structure, disposed on the base structure, wherein an unlocking driving portion of the unlocking structure is exposed to the clearance groove; and

[0009] A handle structure, one side of which is rotatably connected to the base structure via a rotating shaft, the handle structure can cover the external opening and can also flip toward the clearance groove within the base structure. When the handle structure flips to a preset position corresponding to the clearance groove, the handle structure contacts the unlocking drive part.

[0010] In combination with the first aspect, in a possible implementation, the handle structure includes a handle body and an unlocking trigger member, the handle body is rotatably connected to the base structure via the rotating shaft, the unlocking trigger member is arranged on the inner side of the handle body and protrudes from the edge contour line of the handle body, and the unlocking trigger member can contact the unlocking drive part.

[0011] In combination with the first aspect, in a possible implementation, the hidden door handle assembly also includes a handle elastic return member, which is arranged between the base structure and the handle structure and is configured with a pre-tightening force that causes the handle structure to cover the external opening; a damping structure is provided between the base structure and the handle structure, and the damping structure can provide a damping force when the handle structure moves toward the external opening.

[0012] In some embodiments, the damping structure comprises:

[0013] A damping cylinder, closed at one end and open at the other end;

[0014] A piston rod is slidably inserted into the closed end of the damping cylinder; and

[0015] A piston connected to one end of the piston rod facing the open end of the damping cylinder and slidingly sealingly matched with the inner wall of the damping cylinder, a first cavity is formed between the piston and the closed end, and a second cavity is formed between the piston and the open end;

[0016] The first chamber and the second chamber are connected via a control valve, the side wall of the first chamber is also provided with a first vent hole connected to the outside air, and the control valve is a one-way valve for introducing gas from the second chamber into the first chamber;

[0017] One of the damping cylinder and the piston rod is connected to the base structure, and the other of the damping cylinder and the piston rod is connected to the handle structure.

[0018] In some embodiments, the piston is provided with a second vent hole, the second vent hole connects the first chamber and the second chamber, and the control valve is provided at the second vent hole.

[0019] In some embodiments, the control valve includes a valve plate, which covers the side of the second air vent facing the first chamber and is connected to the piston rod or the piston. The valve plate can move away from the second air vent along the moving path of the piston and form a flow gap between the valve plate and the open end face of the second air vent.

[0020] In some embodiments, the valve plate is an annular valve plate, and the valve plate is sleeved on the outer circumference of the piston rod. The piston rod is provided with a limiting boss, and the limiting boss cooperates with the piston to limit the displacement of the edge of the valve plate in the moving direction of the piston.

[0021] In some embodiments, the valve sheet is a flexible valve sheet.

[0022] In some embodiments, the handle structure includes:

[0023] A handle body, rotatably connected to the base structure via the rotating shaft;

[0026] Compared with the prior art, the solution shown in the embodiment of the present application is that, when not in use, the handle structure covers the outer opening of the base structure and is compatible with the appearance of the vehicle door; when in use, the handle structure is pushed inward from the outside to flip it inward. When it flips into the give way groove, the handle structure triggers the unlocking drive unit, and then the vehicle door is unlocked through the unlocking structure. At this time, since the give way groove is located on one side of the outer opening, the right side of the handle structure will go deeper into the give way groove than the side where the handle structure is connected to the rotating shaft. The inclined appearance surface of the handle structure is roughly facing inward, and the user can directly apply an outward pulling force to the handle structure, and finally the vehicle door opens.

[0027] The hidden door handle assembly of the present application realizes the inward rotation and flipping of the handle structure. During the entire flipping process, the handle structure does not protrude from the base structure, and thus does not protrude from the outer panel of the door. The handle structure itself is well protected and not easily bumped. At the same time, due to the inward rotation and flipping design of the handle structure, if the handle structure is frozen, the user can push the handle structure inward from the outside and break the ice at the frozen position. After breaking the ice, the handle structure can still be flipped inward and used normally, avoiding the problem of difficulty in applying force to open the handle structure after it is frozen.

[0028] In a second aspect, an embodiment of the present invention further provides a vehicle, comprising the above-mentioned hidden door handle assembly.

[0029] Compared with the prior art, the solution shown in the embodiment of the present application adopts the above-mentioned hidden door handle assembly, so that the handle structure itself is better protected and is not easily bumped after opening. There is also no problem of the handle structure being difficult to open after being frozen, and the user experience is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Please also read Figures 1 to 5Now, the hidden door handle assembly provided by the present invention is described. The hidden door handle assembly comprises a base structure 1, an unlocking structure 2 and a handle structure 3; the base structure 1 is a box-shaped component, an outer opening 101 is provided on the outer side of the base structure 1, and a clearance groove 102 is formed inside the base structure 1 and located on one side of the outer opening; the unlocking structure 2 is arranged on the base structure, and an unlocking driving part 201 of the unlocking structure 2 is exposed to the clearance groove 102; one side of the handle structure 3 is rotatably connected to the base structure 1 through a rotating shaft 4, and the handle structure 3 can cover the outer opening 101 and can also be turned over toward the clearance groove 102 inside the base structure 1. When the handle structure 3 is turned over to a preset position corresponding to the clearance groove 102, the handle structure 3 contacts the unlocking driving part 201.

[0056] This embodiment exemplarily shows an implementation in which the shaft 4 is arranged perpendicular to the left and right directions and the shaft 4 is located on the upper side of the handle structure 3. Correspondingly, the clearance groove 102 is located on the upper side of the outer opening 101. In the free state, the handle structure 3 is in the following state: Figure 2 When the handle structure 3 is pushed inward, the handle structure 3 is turned inward (such as Figure 3 Continue to push the handle structure 3 until the handle structure 3 flips into the clearance groove 102 and triggers the unlocking drive unit 201, such as Figure 4 As shown, at this time, the human hand does not need to separate from the handle structure 3, and the door can be opened by directly pulling it outward; by releasing the handle structure 3, the handle structure 3 can be reset to the state of covering the outer opening 101, and the unlocking structure 2 also returns to the initial state.

[0057] The implementation in which the shaft 4 is located on the upper side of the handle structure 3 is more convenient for the user to apply force to open the door, but it should be understood that the shaft 4 located on other side edges of the handle structure 3 can also meet the needs of unlocking and opening the door. For example, the shaft 4 is located on the front or bottom side of the handle structure 3. The specific usage process is similar to the aforementioned process and will not be repeated here.

[0058] In this embodiment, in order to facilitate door opening while maintaining aesthetics, the handle structure 3 as a whole is a long strip-shaped component extending along the front-to-back direction. Correspondingly, the outer opening 101 and the base structure 1 are also designed as long structures, whose long axes are parallel to the front-to-back direction. At the same time, the rotating shaft 4 needs to be arranged on the inner side of the handle structure 3.

[0059] Compared with the prior art, the hidden door handle assembly provided in this embodiment has the following characteristics: when not in use, the handle structure 3 covers the outer opening 101 of the base structure 1 and matches the appearance of the door; when in use, the handle structure 3 is pushed inward from the outside to flip it inward. When flipped into the clearance groove 102, the handle structure 3 triggers the unlocking drive unit 201, and then the door is unlocked through the unlocking structure 2. At this time, since the clearance groove 102 is located on one side of the outer opening, the right side of the handle structure 3 will go deeper into the clearance groove 102 than the side where the handle structure 3 is connected to the rotating shaft 4. The inclined appearance surface of the handle structure 3 is roughly facing inward, and the user can directly apply an outward pulling force to the handle structure 3, and finally the door opens.

[0060] The hidden door handle assembly of the present embodiment realizes the inward rotation and flipping of the handle structure 3. During the entire flipping process, the handle structure does not protrude from the base structure 1, and thus does not protrude from the outer panel of the door. The handle structure 3 itself is well protected and not easily bumped. At the same time, due to the inward rotation and flipping design of the handle structure 3, if the handle structure is frozen, the user can push the handle structure 3 inward from the outside and break the ice at the frozen position. After breaking the ice, the handle structure can still be flipped inward and used normally, thus avoiding the problem that the handle structure 3 is difficult to open after being frozen.

[0061] See also Figure 6 and Figure 7 In some embodiments, the handle structure 3 includes a handle body 310 and an unlocking trigger 320. The handle body 310 is rotatably connected to the base structure 1 through the rotating shaft 4. The unlocking trigger 320 is arranged on the inner side of the handle body 310 and protrudes from the edge contour line of the handle body 310. The unlocking trigger 320 can contact the unlocking drive 201. The shape of the unlocking trigger 320 is not limited to a columnar shape, a sheet shape, etc., and can meet the use requirements. This embodiment specifically divides the functions of the handle structure 3. On the one hand, the handle body 310 can meet the overall appearance requirements of the hidden door handle assembly and the contact force requirements of the user; on the other hand, the unlocking trigger 320 realizes the unlocking trigger function, and because the unlocking trigger 320 protrudes from the edge of the handle body 310, the unlocking drive 201 can maintain a reasonable distance from the handle body 310 to avoid interference between the two, and can also reduce the overall layout difficulty of the hidden door handle assembly. The existing unlocking structure 2 can also meet the use requirements, and the use cost is reasonably controlled.

[0062] In this embodiment, the unlocking trigger 320 can extend forward or backward in a direction parallel to the rotation axis 4. In this case, the unlocking structure 2 can be arranged at the front side or rear side of the base structure 1. The dimension of the hidden door handle assembly perpendicular to the front and rear directions is effectively controlled to avoid affecting the arrangement of other components inside the door. The figure exemplarily shows an embodiment in which the unlocking trigger 320 extends forward and the unlocking structure 2 is located at the front side of the base structure 1.

[0063] In other extension modes of the unlocking trigger member 320, the unlocking trigger member 320 extends in a direction perpendicular to the rotating shaft 4, and the unlocking drive unit 201 is correspondingly arranged on the inner side of the base structure 1. This embodiment effectively controls the dimension of the hidden door handle assembly perpendicular to the front-rear direction. Of course, the extension direction of the unlocking trigger member 320 can also be arranged at an angle to the rotating shaft 4. The specific use principle is similar to the above-mentioned embodiment and will not be repeated here.

[0064] See also Figure 6 and Figure 7 In some embodiments of the driving mode of the handle structure 3, the hidden door handle assembly also includes a handle elastic reset member 5, which is arranged between the base structure 1 and the handle structure 3 and is configured with a pre-tightening force to make the handle structure 3 cover the outer opening 101. When the handle structure 3 is opened by hand pushing, the handle elastic reset member 5 produces elastic deformation. If the user cancels the force applied to the handle structure 3, the handle elastic reset member 5 releases the elastic energy, and the handle structure 3 automatically resets. The closing effect of the handle structure 3 is more reliable, and the user experience is better. Based on this embodiment, in order to avoid the problem of pinching the hand due to the handle structure 3 resetting too fast, a damping structure 6 is provided between the base structure 1 and the handle structure 3. The damping structure 6 can provide a damping force when the handle structure 3 moves toward the outer opening 101.

[0065] In this embodiment, the implementation method of the handle elastic reset member 5 includes but is not limited to setting a torsion spring (such as Figure 6 and Figure 7 As shown), a compression spring is arranged between the inner side of the handle structure 3 and the base structure 1, which will not be listed one by one here.

[0066] See also Figures 2 to 6 , Figure 8 and Fig. 9In some embodiments of the damping structure 6, the damping structure 6 includes a damping cylinder 610, a piston rod 620 and a piston 630, one end of the damping cylinder 610 is closed and the other end is open; the piston rod 620 is slidably inserted in the closed end of the damping cylinder 610; the piston 630 is connected to one end of the piston rod 620 facing the open end of the damping cylinder 610, and is slidably sealed with the inner wall of the damping cylinder 610, a first chamber 611 is formed between the piston 630 and the closed end, and a second chamber 612 is formed between the piston 630 and the open end; the first chamber 611 and the second chamber 612 are connected through a control valve 640, and the side wall of the first chamber 611 is also provided with a first vent hole 613 connected to the outside air, and the control valve 640 is a one-way valve for introducing gas from the second chamber 612 into the first chamber 611; one of the damping cylinder 610 and the piston rod 620 is connected to the base structure 1, and the other of the damping cylinder 610 and the piston rod 620 is connected to the handle structure 3. It should be noted that: first, the term "open" refers to the function of satisfying the communication between the second cavity 612 and the outside air, and its implementation is not limited to the following. Figure 8 The end surface of the damping cylinder 610 shown in the figure is completely open, or a vent hole is opened on the corresponding end surface or the outer wall of the damping cylinder 610, a vent pipe is connected, etc., which is not limited here; secondly, the opening method of the first vent hole 613 can be opened on the end surface of the closed end (such as Figure 8 As shown in the figure), it can also be opened on the outer peripheral wall of the damping cylinder 610, which is not limited here; thirdly, the control valve 640 can be a mechanical valve or an electrically controlled valve, which is not limited in this embodiment; fourthly, the setting direction of the damping structure 6 as a whole (that is, the moving direction of the piston rod 620) can be along the up and down direction (such as Figures 1 to 6 As shown), it can also be set in other directions. The setting direction is related to the setting method of the handle structure 3, which will not be repeated here.

[0067] Taking the perspective of the attached figure as an example, the use of the damping structure 6 is described as follows:

[0068] 1) If Figure 2 As shown, when the handle body 310 covers the outer opening 101, the piston 630 is arranged close to the closed end, and the control valve 640 remains in a closed state. At this time, the air pressure P1 in the first chamber 611 and the air pressure P2 in the second chamber 612 are the same.

[0069] 2) The handle body 310 is subjected to the thrust and turns inward, driving the piston rod 620 to move, the volume of the first chamber 611 increases, and the volume of the second chamber 612 decreases. Figure 3As shown. At this time, even if a first air vent 613 is opened on the closed end, it is difficult for the first air vent 613 to quickly take in air due to the limitation of its opening area, and because the second chamber 612 is always ventilated to the outside and maintains a normal pressure state, P1 decreases and P2 remains unchanged in a short period of time, so P2 is greater than P1; the change in the air pressure in the two chambers causes the control valve 640 to open, and the second chamber 612 takes in air into the first chamber 611, and the air pressure in the two chambers gradually returns to a balanced state, eliminating the sense of obstruction during the movement of the handle body 310 and making the handle opening action smoother. This squeezing process continues until the handle body 310 flips to the extreme position, at which time the volume of the first chamber 611 increases to the maximum value, while the volume of the second chamber 612 is compressed to the minimum value, as shown in FIG. Figure 4 shown.

[0070] 3) The force applied to the handle body 310 is cancelled, and the handle body 310 turns outward. During this process, the volume of the first chamber 611 decreases, while the volume of the second chamber 612 increases. Due to the restriction of the first vent hole 613, the air pressure of the first chamber 611 is difficult to quickly maintain equilibrium with the external air pressure. Therefore, P1 increases and P2 remains unchanged for a period of time. At this time, P1 is greater than P2, and the control valve 640 remains closed. Therefore, the first chamber 611 maintains a state of slowly deflated through the first vent hole 613, forming a damping force, which limits the rebound speed of the handle body 310.

[0071] It should also be noted that the ventilation flow rate between the second cavity 612 and the outside world needs to be higher than the gas flow rate of the first vent hole 613. In order to achieve this function, on the one hand, the opening area of ​​the first vent hole 613 can be set smaller, and on the other hand, a control valve structure with a large flow rate can be selected. This embodiment exemplarily shows that a first vent hole 613 is opened on the end face of the closed end, and the open end face of the damping cylinder 610 is completely open, and the aperture of the first vent hole 613 is much smaller than the opening area of ​​the open end.

[0072] The damping structure 6 of this embodiment has a simple and compact overall structure, can provide effective damping effect through changes in external air pressure, and will not produce a sense of obstruction when the handle structure 3 is opened, providing a good user experience.

[0073] In some arrangements of the control valve 640, an external pipeline connecting the first chamber 611 and the second chamber 612 is arranged outside the damping cylinder 610, and a control valve 640 is arranged on the external pipeline, which is not shown in the figure. The control valve 640 can be a solenoid valve, which realizes the opening and closing of the pipeline by means of electric control; the control valve 640 can also be a mechanical one-way valve, and the change of the air pressure in the two chambers can automatically open the one-way valve.

[0074] See also Figure 8 and Fig. 9In other arrangements of the control valve 640, the piston 630 is provided with a second vent hole 631, the second vent hole 631 connects the first chamber 611 and the second chamber 612, and the control valve 640 is arranged at the second vent hole 631. The function of the second vent hole 631 is similar to the "external pipeline" of the aforementioned embodiment, which serves to connect the two chambers, achieves the effect of internal air flow conduction, avoids occupying external space, and has a more compact structure. Among them, the aperture of the second vent hole 631 is larger than the aperture of the first vent hole 613.

[0075] Based on the above embodiments, see Fig. 9 In order to simplify the structure of the control valve 640 and reduce the production cost, the control valve 640 includes a valve plate 641, which covers the side of the second vent hole 631 facing the first chamber 611 and is connected to the piston rod 620 or the piston 630; when the air pressure of the second chamber 612 is greater than the air pressure of the first chamber 611, the valve plate 641 can move away from the second vent hole 631 along the moving path of the piston 630, and form a flow gap with the open end surface of the second vent hole 631; when the air pressure of the second chamber 612 is less than or equal to the air pressure of the first chamber 611, the valve plate 641 keeps covering the second vent hole 631, and the gas does not flow between the two chambers. In this embodiment, the piston rod 620 or the piston 630 is used as the support of the valve plate 641. The valve plate 641 can realize the one-way gas conduction from the second chamber 612 to the first chamber 611, and the structure is simplified.

[0076] On the basis that the control valve 640 includes a valve plate 641, see Figure 8 In order to simplify the assembly form of the valve plate 641, the valve plate 641 is an annular valve plate, and the valve plate 641 is sleeved on the outer periphery of the piston rod 630. The piston rod 620 is provided with a limiting boss 621, and the limiting boss 621 cooperates with the piston 630 to limit the displacement of the edge of the valve plate 641 in the moving direction of the piston 630. Based on this, a plurality of second vent holes 631 are provided, and the plurality of second vent holes 631 are radially distributed on the piston 630 with the piston rod 620 as the center, such as Fig. 9 The annular valve plate 641 cooperates with the radially distributed second vent holes 631, so that the overall opening area of ​​the piston 630 is larger, and the air flow from the second chamber 612 to the first chamber 611 can be quickly conducted, so as to quickly balance the air pressure of the two chambers and eliminate the sense of obstruction when the handle is opened.

[0077] More specifically, the depth direction of the second vent hole 631 can be perpendicular to the moving direction of the piston 630 , or can be inclined relative to the moving direction of the piston 630 , as long as it can meet the requirement of connecting the first chamber 611 and the second chamber 612 .

[0078] See also Figure 8In some specific embodiments of the valve plate 641, the valve plate 641 is a flexible valve plate. When the air pressure in the second chamber 612 is greater than the air pressure in the first chamber 611, the valve plate 641 can be deformed. Based on this, the limiting boss 621 and the piston 630 clamp the inner ring edge of the fixed valve plate 641. If the gap between the limiting boss 621 and the piston 630 is less than or equal to the thickness of the valve plate 641, the outer periphery of the valve plate 641 will be tilted, and the central area will not move; when the air pressure in the second chamber 612 is less than or equal to the air pressure in the first chamber 611, the valve plate 641 will fit the surface of the piston 630 as a whole, blocking the gas flow between the two chambers. If the gap between the limiting boss 621 and the piston 630 is greater than the thickness of the valve plate 641, the valve plate 641 can not only deform, but also move along the axial direction of the piston rod 620, increasing the air flow speed to the maximum length; when the air pressure of the second chamber 612 is less than or equal to the air pressure of the first chamber 611, the valve plate 641 is entirely attached to the surface of the piston 630, blocking the gas flow between the two chambers. In this embodiment, the implementation of the valve plate 641 includes but is not limited to an EPDM rubber component, and the other implementations are not listed here one by one.

[0079] In other specific embodiments of the valve plate 641, the valve plate 641 is a rigid valve plate, and the limiting boss 621 and the piston 630 are spaced apart, and the width of the gap is greater than the thickness of the valve plate 641. The valve plate 641 can move in the space between the limiting boss 621 and the piston, and then when the valve plate 641 approaches the limiting boss 621, a flow gap is formed between the valve plate 641 and the surface of the lower piston 630. Its specific working principle is similar to that of the aforementioned flexible valve plate 641, and will not be repeated here. In this embodiment, the implementation of the valve plate 641 includes but is not limited to a resin component, and the other implementations are not listed here one by one.

[0080] In some embodiments not shown in the figures, the valve plate 641 can also be directly connected to the piston 630. For example, part of the edge of the valve plate 641 is connected to the piston 630 by bonding or the like. In a free state, the part of the valve plate 641 that is not connected to the piston 630 can be attached to the surface of the piston 630 to cover the second air vent 631. When the space in the second chamber 612 is compressed, the valve plate 641 is lifted up, and a flow gap is formed between the part that is not connected to the piston 630 and the piston 630.

[0081] See also Figures 1 to 7In some embodiments, the handle structure 3 includes a handle body 310, an unlocking trigger 320 and a damping connector 330; the handle body 310 is rotatably connected to the base structure 1 through a rotating shaft 4; the unlocking trigger 320 is located on the inner side of the handle body 310 and protrudes from the edge contour line of the handle body 310 in a direction parallel to the rotating shaft 4, and the unlocking trigger 320 can contact the unlocking drive 201; the damping connector 330 and the unlocking trigger 320 are distributed along the axial direction of the rotating shaft 4, and the damping connector 330 is connected between the unlocking trigger 320 and the handle body 310, and the damping connector 330 is connected to the piston rod 620. In this embodiment, the unlocking trigger 320 and the damping connector 330 are integrated, and the two are connected to the handle body 310 through a point, which simplifies the overall structure of the handle structure 3; at the same time, the unlocking structure 2 and the damping structure 6 are closer, and the overall structure is more compact.

[0082] Based on the above embodiments, see Figures 2 to 4 and Figure 8 The damping cylinder 610 is fixed to the base structure 1, and a guide hole 622 is formed at the protruding end of the piston rod 620. The guide hole 622 is a long hole extending along the swing direction of the damping connector 330; the damping connector 330 is passed through the guide hole 622 and slides with the piston rod 620 along the long axis direction of the guide hole 622. During the movement of the damping connector 330, the piston rod 620 only moves along its own axial direction, thereby realizing the fixed arrangement of the damping structure 6 and the base structure 1, and there is no need to set a space on the base structure 1 to avoid the movement of the damping structure 6.

[0083] In some embodiments, a connecting bracket 311 is provided on the inner side of the handle body 310. Figure 6 and Figure 7 As shown, the connecting bracket 311 is L-shaped as a whole and protrudes inward. One end of the connecting bracket 311 is connected to the handle 310, and the other end is rotatably adapted to the rotating shaft 4. As an extension of the handle body 310, the connecting bracket 311 makes the connection between the handle body 310 and the rotating shaft 4 more flexible without occupying too much internal space of the base structure 1; at the same time, the L-shaped design ensures the structural strength of the connecting bracket 311 itself, avoiding the risk of deformation and fracture of the connecting bracket 311 after repeated use; in addition, due to the inward convex design of the connecting bracket 311, when the handle body 310 is flipped to the extreme position of abutting against the unlocking drive part 201, the connecting bracket 3100 can also abut against the inner end surface of the inner opening 101, avoiding the problem of damage to the unlocking structure 2 caused by excessive flipping of the handle body 310.

[0084] In some embodiments, the base structure 1 may be formed as follows: Figures 1 to 6As shown in the structure, the base structure 1 includes a mounting box 110, an inner cover 120, an outer cover 130 and a sealing gasket 140; openings are arranged on the outer and inner sides of the mounting box 110, and the inner cover 120 covers the inner opening of the mounting box 110; the outer cover 130 is an annular cover body, and is installed at the outer opening of the mounting box 110, and the outer cover 130 forms the outer opening 101 of the base structure 1; the sealing gasket 140 is arranged on the outer side of the outer cover 130, and after the hidden door handle assembly is installed on the vehicle door, the sealing gasket 130 abuts against the inner side of the door outer panel to ensure the sealing of the assembly.

[0085] In some embodiments, the unlocking structure 2 may be implemented as follows: Figure 1 and Figure 6 In the structure shown, the unlocking structure 2 includes a pull wire 210, a pull wire fixing block 220 and a fixing block reset elastic member; an unlocking space is opened on the side wall of the installation box 110, the pull wire fixing block 220 is rotatably connected to the side wall of the installation box 110, and is located outside the base structure 1, the pull wire fixing block 220 is formed with an unlocking drive part 201, and the unlocking drive part 201 extends into the unlocking space; one end of the pull wire 210 is connected to the pull wire fixing block 220, and the other end is connected to the installation box 110; the fixing block reset elastic member is arranged between the installation box 110 and the pull wire fixing block 220. The handle body 310 drives the unlocking trigger member 320 to swing synchronously. The unlocking trigger member 320 gradually approaches the unlocking drive part 201 during the swinging process, and finally drives the pull wire fixing block 220 to rotate by squeezing the unlocking drive part 201. The rotation of the pull wire fixing block 220 will pull the pull wire 210, and finally achieve unlocking; after the human hand leaves the handle body 310, the handle body 310 automatically resets, the pressure of the unlocking trigger member 320 on the unlocking drive part 201 is released, the fixing block reset elastic member drives the pull wire fixing block 220 to reset, and the pull wire 210 is released from the pulled state.
