Description

Technical Field

[0001] This invention relates to the field of transportation vehicles, and more specifically, to a door handle assembly, a door, and a vehicle. Background Technology

[0002] With the production and sales of new energy vehicles increasing year by year, the exterior door handles of new energy vehicles are gradually developing towards electric retractable exterior door handles. Electric retractable door handles are integrated with the vehicle body through a telescopic mechanism, which can effectively reduce the wind resistance caused by exposed exterior door handles and save energy to a certain extent. On the other hand, when the key approaches the vehicle, the retractable door handle will automatically extend to welcome the driver and retract after the driver enters the vehicle, which also caters to the sense of ceremony and technology required for electric vehicles.

[0003] Currently, commercially available concealed door handle assemblies generally include a base, a push rod, a forearm and a rear arm that are pushed and swung by the push rod, and a handle that is moved by the forearm and rear arm. Due to the shape of the handle itself, the forearm and rear arm can be the same or different shapes. For door handle assemblies with different shaped forearms and rear arms, the push rod typically pushes the forearm to swing through other moving transmission components, enabling the forearm and rear arm to push the handle horizontally. This structure results in more parts, a more complex assembly process, and higher costs. Furthermore, commercially available door handle assemblies generally have limited ice-breaking capabilities. Summary of the Invention

[0004] The main objective of this invention is to provide a door handle assembly, a door, and a vehicle to solve the problems of numerous parts and high cost in existing door handle assemblies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a door handle assembly is provided, comprising: a base having a clearance opening; a handle having a flush position flush with the clearance opening and a ready position extending outward from the clearance opening; a forearm, a first end of which is pivotally connected to the front end of the handle via a first forearm pivot axis, and a second end of which is pivotally connected to the base via a second forearm pivot axis; and a rear arm, a first end of which is pivotally connected to the rear end of the handle via a first rear arm pivot axis, the base having a guide structure arranged in a front-rear direction, and the second end of the rear arm being pivotable via a second rear arm pivot axis. The handle is positioned at the guide structure so that the second rear arm pivot can move in the front-rear direction; the push rod includes a rod body, a first pushing structure at the front end of the push rod, and a second pushing structure at the rear end of the push rod. A mating surface is provided on the forearm. The first pushing structure pushes and engages with the mating surface, and the second pushing structure pushes and engages with the second rear arm pivot so that the handle is pushed from the flush position to the ready position. The lines connecting the first forearm pivot, the first rear arm pivot, the second rear arm pivot, and the pushing points M of the first pushing structure and the mating surface form a parallelogram N so that the handle is pushed out horizontally.

[0006] In one embodiment, the handle has a closed handle hole, a first forearm pivot is located on the front side of the handle hole, a second forearm pivot is located on the front side of the handle, a first rear arm pivot is located at the rear end of the inner side of the handle, and a second rear arm pivot is located on the inner side of the handle.

[0007] In one embodiment, the forearm includes a forearm body and a mating block fixedly disposed below the forearm body, with the mating surface located on the mating block.

[0008] In one embodiment, a first elastic reset structure and a second elastic reset structure are respectively provided between the forearm, the handle, and the seat. Under the reset action of the first elastic reset structure and the second elastic reset structure, the handle can return from the ready position to the flush position.

[0009] In one embodiment, the guide structure includes a guide groove in which the second rear arm pivot shaft is pivotally disposed.

[0010] In one embodiment, the handle also has an open position with the rear end raised, and the door handle assembly further includes a zipper fixing device, including a zipper fixing block movably disposed on the seat, the zipper fixing block having an initial fixing position and an unlocking position for unlocking the door, wherein when the handle moves from the ready position to the open position, the second rear arm pivot pushes the zipper fixing block to move the zipper fixing block from the initial position to the unlocking position.

[0011] In one embodiment, the zipper fixing device further includes a fixing block reset member disposed between the zipper fixing block and the base. When the handle loses external force, the zipper fixing block returns from the unlocked position to the initial position under the reset action of the fixing block reset member, and the rear arm moves under the driving force of the zipper fixing block to drive the handle to return from the open position to the ready position.

[0012] In one embodiment, the guide structure includes a guide groove, and a second rear arm pivot shaft is pivotally inserted into the guide groove. The guide groove includes a first groove segment extending forward and backward and an arc-shaped second groove segment. A zipper fixing block is rotatably disposed on the base. The center of the second groove segment coincides with the rotation center of the zipper fixing block. When the handle is in the flush position and the ready position, the second rear arm pivot shaft is located in the first groove segment. When the handle is in the ready position and the open position, the second rear arm pivot shaft is located in the second groove segment.

[0013] In one embodiment, the door handle assembly further includes a collision locking block, which is rotatably disposed on the seat. The collision locking block has a locking position for locking the zipper fixing block and a clearance position that does not interfere with the zipper fixing block. When the door handle assembly is subjected to a collision force, the collision locking block moves from the clearance position to the locking position under the action of inertial force to stop the zipper fixing block from moving to the unlocking position.

[0014] In one embodiment, the door handle assembly further includes a first micro switch and a second micro switch arranged at a distance from front to back on the seat. The push rod also includes a mating protrusion disposed on the rod body. When the handle is in the flush position, the mating protrusion mates with the first micro switch, and when the handle is in the ready position, the mating protrusion mates with the second micro switch.

[0015] In one embodiment, the base includes a box having an installation opening, a cover disposed over the installation opening, and an installation structure disposed on the box, with a clearance opening located on the side wall of the box opposite to the installation opening.

[0016] In one embodiment, the mounting structure includes a mounting base having a first mounting hole, an adjusting member adjustablely disposed within the first mounting hole, and a connecting member disposed on the adjusting member and connected to the vehicle door, wherein the first mounting hole extends in the direction in which the handle extends.

[0017] In one embodiment, the adjusting member includes an adjusting block, a pressure plate, and an elastic member disposed between the adjusting block and the pressure plate. The adjusting block includes a central block and a deformable member surrounding the outer periphery of the central block. The deformable member is provided with a first snap-fit ​​structure, and a second snap-fit ​​structure opposite to the first snap-fit ​​structure is provided on the inner wall of the first mounting hole. The deformable member has a mating position for engaging the first snap-fit ​​structure and the second snap-fit ​​structure and a separating position for separating the first snap-fit ​​structure and the second snap-fit ​​structure.

[0018] In one embodiment, a bayonet is formed between the deformable part and the center block. The pressure plate includes a pressure plate body and a buckle disposed on the pressure plate body. The buckle engages with the bayonet. The surface of the buckle that engages with the bayonet is an inclined surface. The first engagement structure is located at the bayonet on the outer surface of the deformable part. A connector passes through the adjustment block and the pressure plate. The connector drives the pressure plate to move toward the adjustment block so that the bayonet of the deformable part expands outward so that the deformable part switches from a separated position to a engaged position.

[0019] In one embodiment, the adjusting member is provided with a second mounting hole, and the connecting member passes through the second mounting hole. The diameter of the second mounting hole is larger than the diameter of the connecting member.

[0020] According to another aspect of the present invention, a vehicle door is provided, comprising: a vehicle door handle assembly, wherein the vehicle door handle assembly is the aforementioned vehicle door handle assembly.

[0021] According to a final aspect of the present invention, a vehicle is provided, comprising: a door, the door being the door described above.

[0022] Applying the technical solution of this invention, when the handle needs to be extended outward to the ready position, the push rod moves forward. During the movement of the push rod, the first pushing structure engages with the mating curved surface pushing mechanism, and the second pushing structure engages with the second rear arm pivot axis pushing mechanism, so that the forearm and rear arm swing simultaneously to drive the handle to extend. More importantly, throughout the entire process of the push rod movement, the line connecting the first forearm pivot axis, the first rear arm pivot axis, the second rear arm pivot axis, and the pushing point M of the first pushing structure and the mating curved surface pushing mechanism is always a parallelogram N, thus achieving the purpose of horizontally extending the handle. The above structure optimizes the shape of the contact point between the push rod and the forearm, enabling near-parallel extension and retraction even for forearms and rear arms of unequal length, improving the synchronization of the front and rear end extension and retraction of the handle. Furthermore, while achieving the above objectives, the transmission components mentioned in the background art are eliminated, thus reducing the number of parts, simplifying the assembly process, and lowering production costs.

[0023] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0048] like Figures 1 to 8As shown, the door handle assembly of this embodiment includes: a base 10, a handle 20, a forearm 30, a rear arm 40, and a push rod 50. The base 10 has a clearance opening 111. The handle 20 has a flush position with the clearance opening 111 and a ready position extending outward from the clearance opening 111. The first end of the forearm 30 is pivotally connected to the front end of the handle 20 via a first forearm pivot 31, and the second end of the forearm 30 is pivotally connected to the base 10 via a second forearm pivot 32. The first end of the rear arm 40 is pivotally connected to the rear end of the handle 20 via a first rear arm pivot 41. The base 10 is provided with a guide structure 112 arranged in the front-rear direction, and the second end of the rear arm 40 is pivotally mounted on the guide structure 112 via the second rear arm pivot 42, so that the second rear arm pivot 42 can move in the front-rear direction. The push rod 50 includes a rod body 51, a first pushing structure 52 disposed at the front end of the push rod 50, and a second pushing structure 53 disposed at the rear end of the push rod 50. A mating surface 341 is provided on the forearm 30. The first pushing structure 52 pushes and engages with the mating surface 341. The second pushing structure 53 pushes and engages with the second rear arm pivot 42 to push the handle 20 from the flush position to the ready position. The line connecting the pushing points M of the first forearm pivot 31, the first rear arm pivot 41, the second rear arm pivot 42, the first pushing structure 52, and the mating surface 341 forms a parallelogram N to push the handle 20 out horizontally.

[0049] Applying the technical solution of this embodiment, when the handle 20 needs to extend outward to the ready position, the push rod 50 moves forward. During the movement of the push rod 50, the first pushing structure 52 engages with the mating surface 341, and the second pushing structure 53 engages with the second rear arm pivot 42, so that the forearm and rear arm swing simultaneously to drive the handle 20 to extend. More importantly, throughout the entire movement of the push rod 50, the line connecting the first forearm pivot 31, the first rear arm pivot 41, the second rear arm pivot 42, and the pushing point M of the first pushing structure 52 and the mating surface 341 is always a parallelogram N, thus achieving the purpose of horizontally extending the handle 20 (i.e., the outer surface of the handle 20 can remain parallel to the door). The above structure, by optimizing the shape of the contact point between the push rod 50 and the forearm 30 (i.e., the shape of the mating surface 341), enables the forearm and rear arms of unequal length to extend and retract almost parallel, improving the synchronization of the extension and retraction of the front and rear ends of the handle. Furthermore, while achieving the aforementioned objectives, the transmission components mentioned in the background art are eliminated, thereby reducing the number of parts, simplifying the assembly process, and lowering production costs.

[0050] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in this embodiment, the handle 20 is provided with a closed handle hole 21. Due to the special shape of the handle 20, the seat 10 is occupied by the handle 20, which takes up a lot of space. Therefore, it is necessary to rationally design the positions of the first forearm pivot 31, the second forearm pivot 32, the first rear arm pivot 41, and the second rear arm pivot 42. Specifically, in this embodiment, the first forearm pivot 31 is located on the front side of the handle hole 21, the second forearm pivot 32 is located on the front side of the handle 20, the first rear arm pivot 41 is located at the rear end of the inner side of the handle 20, and the second rear arm pivot 42 is located on the inner side of the handle 20. The above structure makes full use of the space inside the seat 10 and rationally designs the positions of the first forearm pivot 31, the second forearm pivot 32, the first rear arm pivot 41, and the second rear arm pivot 42, as well as the shape of the mating curved surface 341. This ensures that the handle can be moved smoothly to the ready position without increasing the volume of the door handle assembly, thus achieving a miniaturized design.

[0051] like Figure 1 , Figure 4 , Figure 6 and Figure 8 As shown, in this embodiment, the forearm 30 includes a forearm body 33 and a mating block 34 fixedly disposed below the forearm body 33, with the mating curved surface 341 located on the mating block 34. Specifically, in this embodiment, the forearm body 33 and the mating block 34 are integrally formed, which can further simplify the assembly process and reduce production costs.

[0052] like Figure 1 , Figure 5 and Figure 10 As shown, in this embodiment, a first elastic reset structure 60 and a second elastic reset structure 70 are respectively provided between the forearm 30, the handle 20, and the seat 10. Under the reset action of the first elastic reset structure 60 and the second elastic reset structure 70, the handle 20 can return from the ready position to the flush position. The above structure is simple, allowing the handle 20 to reset smoothly. Preferably, in this embodiment, the first elastic reset structure 60 is a first torsion spring sleeved on the first forearm pivot 31, with one leg of the first torsion spring connected to the handle and the other leg connected to the forearm 30; the second elastic reset structure 70 is a second torsion spring sleeved on the second forearm pivot 32, with one leg of the second torsion spring connected to the forearm 30 and the other leg connected to the seat 10. Preferably, in this embodiment, the second elastic reset structure 70 is a double torsion spring. The above structure makes the handle 20 more resistant to force and less prone to twisting, and the gap between the handle 20 and the sides of the seat 10 is more uniform.

[0053] like Figure 2 , Figure 3 and Figure 7As shown, in this embodiment, the guide structure 112 includes a guide groove, and the second rear arm pivot shaft 42 is pivotally inserted into the guide groove. The above structure is simple, provides reliable guidance, and is easy to install.

[0054] like Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, in this embodiment, the handle 20 also has an open position with its rear end raised. The door handle assembly further includes a zipper fixing device 80, which includes a zipper fixing block 81 movably mounted on the seat 10. The zipper fixing block 81 has an initial fixing position and an unlocking position for unlocking the door. When the handle 20 moves from the ready position to the open position, the second rear arm pivot 42 pushes the zipper fixing block 81 to move it from the initial position to the unlocking position. Specifically, when the handle 20 is subjected to external force, the rear end of the handle 20 is raised, causing the handle 20 to swing the rear arm 40. The second rear arm pivot 42 on the rear arm 40 moves accordingly, thereby moving the zipper fixing block 81 from the initial position to the unlocking position. In the above structure, the movement of the zipper fixing block 81 from the initial position to the unlocking position is achieved by a mechanical structure, thus making the door unlocking more reliable.

[0055] like Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, in this embodiment, the zipper fixing device 80 further includes a fixing block reset member 82 disposed between the zipper fixing block 81 and the seat 10. When the handle 20 loses external force, the zipper fixing block 81 returns from the unlocked position to the initial position under the reset action of the fixing block reset member 82. The rear arm 40 moves under the driving force of the zipper fixing block 81 to drive the handle 20 from the open position to the ready position. Specifically, the fixing block reset member 82 of the zipper fixing device 80 can apply a reset force to the rear arm 40. Once the handle 20 loses external force, the rear arm 40 begins to reset. During the reset process, the rear arm 40 will drive the handle 20 to move towards the ready position until the handle moves to the ready position. The above structure does not require additional reset structures to reset the rear arm 40, which reduces the number of parts, simplifies the assembly process, and reduces production costs. On the other hand, it effectively improves the mechanical transmission efficiency of the handle, thereby reducing the handle opening force.

[0056] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the guide structure 112 includes a guide groove, and the second rear arm pivot shaft 42 is pivotally inserted into the guide groove. The guide groove includes a first groove segment 1121 extending forward and backward and an arc-shaped second groove segment 1122. The zipper fixing block 81 is rotatably mounted on the base 10. The center of the second groove segment 1122 coincides with the rotation center of the zipper fixing block 81. When the handle 20 is in the flush position and the ready position, the second rear arm pivot shaft 42 is located in the first groove segment 1121. When the handle 20 is in the ready position and the open position, the second rear arm pivot shaft 42 is located in the second groove segment 1122. The above structure is simple, provides reliable guidance, and is easy to install.

[0057] like Figure 2 , Figure 3 , Figure 7 , Figure 9 and Figure 11 As shown, in this embodiment, the door handle assembly further includes a collision locking block 90, which is rotatably mounted on the seat 10. The collision locking block 90 has a locking position that locks the zipper fixing block 81 and a clearance position that does not interfere with the zipper fixing block 81. When the door handle assembly is subjected to a collision force, the collision locking block 90 moves from the clearance position to the locking position under the action of inertial force to stop the zipper fixing block 81 from moving to the unlocking position. Specifically, in this embodiment, the collision locking block 90 has a notch, and the zipper fixing block 81 has a protrusion. When the door handle assembly is subjected to a collision force, the collision locking block 90 rotates to the locking position under the action of inertial force. At this time, once the zipper fixing block 81 is subjected to an external force, the protrusion on the zipper fixing block 81 will abut against the wall of the notch, thereby preventing the zipper fixing block 81 from rotating and ensuring that the door will not be opened at the moment of collision, thus ensuring the safety of the vehicle.

[0058] like Figure 9 As shown, in this embodiment, the door handle assembly further includes a first microswitch 101 and a second microswitch 102 arranged at a distance from each other on the seat 10. The push rod 50 also includes a mating protrusion 54 disposed on the rod body 51. When the handle 20 is in the flush position, the mating protrusion 54 engages with the first microswitch 101; when the handle 20 is in the ready position, the mating protrusion 54 engages with the second microswitch 102. Specifically, when the mating protrusion 54 contacts the second microswitch 102, the second microswitch 102 detects a position signal and controls the push rod 50 to stop pushing. The dual-sensor technology makes the detection of the handle position more accurate. Of course, in other embodiments, the first microswitch 101 and the second microswitch 102 can be replaced with Hall sensors, and the push rod 50 can be provided with a first magnet and a second magnet at intervals.

[0059] like Figure 3 and Figure 7 As shown, in this embodiment, the base 10 includes a box 11 with an installation opening, a cover 12 covering the installation opening, and an installation structure 13 disposed on the box 11. A clearance opening 111 is located on the side wall of the box 11 opposite to the installation opening. The above structure is simple; the base 10 adopts an integral structural design, and the installation structure 13 is disposed on the box 11, which is beneficial for improving the assembly accuracy of the handle, reducing the number of product parts, and lowering component procurement costs. Furthermore, the addition of the cover 12 improves product sealing and reduces motor noise, while also enhancing the product's surface smoothness.

[0060] like Figures 12 to 14 As shown, in this embodiment, the mounting structure 13 includes a mounting base 132 with a first mounting hole 131, an adjusting member 133 adjustablely disposed within the first mounting hole 131, and a connecting member 134 disposed on the adjusting member 133 and connected to the door. The first mounting hole 131 extends in the direction in which the handle 20 extends. This structure allows the position of the door handle assembly to be adjusted in the inward and outward directions of the door, ensuring that the door handle assembly is flush with the outer surface of the door. Preferably, in this embodiment, the door handle assembly can be adjusted within ±3mm in the inward and outward directions of the door.

[0061] like Figures 13 to 17 As shown, in this embodiment, the adjusting member 133 includes an adjusting block 135, a pressure plate 136, and an elastic member 137 disposed between the adjusting block 135 and the pressure plate 136. The adjusting block 135 includes a central block 1351 and a deformable member 1352 surrounding the outer periphery of the central block 1351. The deformable member 1352 is provided with a first snap-fit ​​structure 1353, and the inner wall of the first mounting hole 131 is provided with a second snap-fit ​​structure 138 opposite to the first snap-fit ​​structure 1353. The deformable member 1352 has a mating position for engaging the first snap-fit ​​structure 1353 and the second snap-fit ​​structure 138, and a separating position for separating the first snap-fit ​​structure 1353 and the second snap-fit ​​structure 138. The above structure allows the position of the door handle assembly in the inward and outward directions of the door to be better maintained in the preset adjusting position, thereby ensuring the final effect of installing the door handle assembly on the door.

[0062] like Figures 13 to 17As shown, in this embodiment, a bayonet 139 is formed between the deformable part 1352 and the center block 1351. The pressure plate 136 includes a pressure plate body 1361 and a buckle 1362 disposed on the pressure plate body 1361. The buckle 1362 engages with the bayonet 139. The surface of the buckle 1362 that engages with the bayonet 139 is an inclined surface. The first engagement structure 1353 is located at the bayonet 139 on the outer surface of the deformable part 1352. The connector 134 passes through the adjusting block 135 and the pressure plate 136. The connector 134 drives the pressure plate 136 to move toward the adjusting block 135 so that the bayonet 139 of the deformable part 1352 expands outward so that the deformable part 1352 switches from the separated position to the engaged position. Specifically, in this embodiment, the first snap-fit ​​structure 1353 and the second snap-fit ​​structure 138 are threaded structures. When the connector 134 drives the pressure plate 136 to move toward the adjusting block 135, the snap-fit ​​opening 139 of the deformable part 1352 expands outward, and the threaded structure at the snap-fit ​​opening 139 engages with the threaded structure on the inner wall of the first mounting hole 131. As the connector 134 continues to screw, the snap-fit ​​force of the first snap-fit ​​structure 1353 and the second snap-fit ​​structure 138 increases, thereby making the adjusting part 133 firmly fixed on the mounting base 132.

[0063] like Figure 14 As shown, in this embodiment, the adjusting member 133 is provided with a second mounting hole 1331, and the connecting member 134 passes through the second mounting hole 1331. The diameter of the second mounting hole 1331 is larger than the diameter of the connecting member 134. This structure allows the position of the door handle assembly to be adjusted in a direction perpendicular to the inside and outside of the door, thereby satisfying the adjustment of the door handle gap and surface difference. Preferably, in this embodiment, the door handle assembly can be adjusted by ±2.5mm in a direction perpendicular to the inside and outside of the door.

[0064] It should be noted that, in this embodiment, the extension and retraction control of the handle 20 between the flush position and the ready position can be controlled via the car key, central control switch, or touch capacitive sensor. The mounting method is optional, safe, and intelligent. After the vehicle starts and reaches a certain speed, the handle 20 automatically retracts; when the car encounters an obstacle, the handle 20 automatically retracts; when reversing or parallel parking, the handle 20 automatically retracts.

[0065] It should also be noted that, in addition to the functions mentioned above, the door handle assembly also has an emergency door handle assistance function: when the vehicle is involved in a collision, the door handles automatically extend and unlock, allowing rescue personnel to directly pull the door handles to open the doors and carry out rescue operations.

[0066] Currently, in cold regions, door handles are easily frozen solid, making it difficult to open car doors. To address this issue, such as... Figure 1As shown, in this embodiment, the distance between the second forearm pivot 32 and the jacking point M is between 23cm and 28cm. This structure increases the length of the lever arm, thereby increasing the transmission lever ratio and thus increasing the ice-breaking thrust. The measured ice-breaking force reaches 170N (tested under 12V standard voltage conditions) > 150N (industry experience requirement). In cold regions, if the handle 20 is frozen, it can be activated with the car key, and the handle 20 will automatically push outwards, automatically pushing outwards 3 times each time. It can be opened 3 times consecutively, with each 100% thrust reaching over 170N, ensuring worry-free ice breaking.

[0067] like Figure 1 and Figure 6 As shown, in this embodiment, the door handle assembly also includes a drive device 110 for moving the push rod 50.

[0068] The process of extending and retracting the handle in this embodiment is described in detail below:

[0069] When the driver approaches the front door (usually within 1 meter), the door controller detects the door key signal. After the driver touches the capacitive sensor on the handle 20, the door handle moves from the flush position. Figure 1 Extend to the ready position. Figure 6 When the touch capacitive sensor is activated, the door control unit in the vehicle body sends a signal to the drive unit 110. The actuator motor of the drive unit 110 then starts working, pushing the push rod 50. The push rod 50 simultaneously pushes the front arm 30 and the rear arm 40 to extend the handle 20 in parallel. When it reaches a certain position, the push rod 50 stops pushing, indicating that the vehicle has reached the ready position.

[0070] The driver pulls handle 20, which rotates the second rear arm pivot 42 and simultaneously causes the zipper locking block 81 to slide. When handle 20 reaches the open position... Figure 10 When the sliding stroke of the zipper fixing block 81 reaches the cable unlocking stroke, the door lock is opened.

[0071] When the driver releases the handle 20, the handle 20 returns to the ready state under the action of the fixed block reset member 82 and the first elastic reset structure 60.

[0072] Touching the capacitive sensor again, the gate controller receives the sensor signal and simultaneously sends a command to the actuator motor. The actuator motor drives the push rod 50 to retract, the forearm 30 retracts under the action of the second elastic reset structure 70, and the rear arm 40 retracts under the action of the forearm 30 and the first elastic reset structure 60. At this time, the handle returns to the flush position.

[0073] It should be noted that, in this embodiment, the extension and retraction control of the handle 20 between the flush position and the ready position can be controlled via the car key, central control switch, or touch capacitive sensor. The mounting method is optional, safe, and intelligent. After the vehicle starts and reaches a certain speed, the handle 20 automatically retracts; when the car encounters an obstacle, the handle 20 automatically retracts; when reversing or parallel parking, the handle 20 automatically retracts.

[0074] It should also be noted that, in addition to the functions mentioned above, the door handle assembly also has an emergency door handle assistance function: when the vehicle is involved in a collision, the door handles automatically extend and unlock, allowing rescue personnel to directly pull the door handles to open the doors and carry out rescue operations.

[0075] This application also provides a vehicle door, an embodiment of which includes a door handle assembly, the door handle assembly being the aforementioned door handle assembly. Since the aforementioned door handle assembly has advantages such as simple structure, low cost, simple assembly, and strong ice-breaking ability, the vehicle door having it also possesses these advantages.

[0076] This application also provides a vehicle, and an embodiment of the vehicle according to this application includes: a door, the door being the aforementioned door. Since the aforementioned door has the advantages of simple structure, low cost, simple assembly, and strong ice-breaking ability, the vehicle having it also possesses the aforementioned advantages.
