[0002] Concealed door handles can reduce wind resistance, improve fuel economy and driving range, and also make the vehicle's appearance more streamlined, enhancing its overall technological feel and aesthetics. Currently, the height difference between the front and rear ends of concealed door handles changes during extension, causing a misalignment between the door and the handle. This results in uneven gaps between the handle and the door, affecting the vehicle's appearance and overall quality, and may even make the handle difficult to pull, increasing the difficulty of opening the door and impacting ease of use. Utility Model Content
[0003] This application provides a handle assembly, a door, and a vehicle to at least partially solve the aforementioned technical problems.
[0004] To achieve the above objectives, according to a first aspect of this application, a handle assembly is provided, including a base, a handle, and a drive mechanism. The handle has an initial state and an extended state, and is configured to retract into the base in the initial state and extend out of the base in the extended state. The handle has a front end and a rear end along its length direction. The drive mechanism is synchronously driven connected to the front end and the rear end to drive the front end and the rear end to extend and retract synchronously.
[0005] In some embodiments, the driving mechanism includes a driving member and a pushing member. The pushing member is movably disposed on the base. The driving member is driven to drive the pushing member. The pushing member is synchronously driven to drive the front end and the rear end. The driving member drives the pushing member to move, thereby causing the handle to extend and retract.
[0006] In some embodiments, the drive mechanism further includes a first swing arm and a second swing arm. One end of the first swing arm is connected to the front end to form a first rotating joint, and the other end is connected to the base to form a second rotating joint. One end of the second swing arm is connected to the rear end to form a third rotating joint, and the other end is connected to the base to form a fourth rotating joint. The pusher is synchronously driven to the front end and the rear end through the first swing arm and the second swing arm, respectively.
[0007] In some embodiments, the first revolute joint has a first rotation center line, the second revolute joint has a second rotation center line, the third revolute joint has a third rotation center line, and the fourth revolute joint has a fourth rotation center line. The line connecting the first rotation center line and the second rotation center line is parallel to the line connecting the third rotation center line and the fourth rotation center line, and the distance between the first rotation center line and the second rotation center line is equal to the distance between the third rotation center line and the fourth rotation center line.
[0008] In some embodiments, the second swing arm includes a swing arm body and a connecting rod. One end of the swing arm body is connected to the base to form the fourth revolute joint, and the other end is connected to the connecting rod to form the fifth revolute joint. The end of the connecting rod away from the swing arm body is connected to the rear end to form the third revolute joint.
[0009] In some embodiments, the connecting rod is connected to the rear end via a first pivot, and the handle assembly further includes a support member rotatably disposed on the swing arm body, the support member being configured to support the first pivot during the extension and retraction of the handle.
[0010] In some embodiments, the second swing arm is provided with a first limiting portion, and the support member abuts against the first limiting portion during the extension and retraction of the handle.
[0011] In some embodiments, the handle has an emergency state, wherein the handle is configured such that the front end is pressed down and the rear end is raised in the emergency state.
[0012] In some embodiments, the base is provided with a second limiting part. During the switching of the handle between the initial state and the emergency state, the second limiting part restricts the support member from abutting the first limiting part, so that a clearance channel is formed between the support member and the first limiting part. The first rotating shaft is located within the clearance channel during the switching of the handle between the initial state and the emergency state.
[0013] In some embodiments, the pusher is provided with a first guide ramp and a second guide ramp, the first swing arm is drivenly connected to the first guide ramp, and the second swing arm is drivenly connected to the second guide ramp.
[0014] In some embodiments, the first guide ramp includes a first ramp surface and a second ramp surface, the slope of the first ramp surface being less than the slope of the second ramp surface, and during the process of the handle switching from the initial state to the extended state, the first swing arm first contacts the first ramp surface and then contacts the second ramp surface; and / or, the second guide ramp includes a third ramp surface and a fourth ramp surface, the slope of the third ramp surface being less than the slope of the fourth ramp surface, and during the process of the handle switching from the initial state to the extended state, the second swing arm first contacts the third ramp surface and then contacts the fourth ramp surface.
[0015] In some embodiments, the first swing arm is rolledly connected to the first guide ramp, and / or the second swing arm is rolledly connected to the second guide ramp.
[0016] In some embodiments, the handle also has an unlocked state, and the handle assembly further includes an unlocking member connected to the base. During the process of the handle switching from the extended state to the unlocked state, the unlocking member moves under the drive of the second swing arm and triggers the unlocking mechanism to unlock the door.
[0017] In some embodiments, the unlocking member is rotatably disposed on the base, and during the process of the handle switching from the extended state to the unlocked state, the unlocking member rotates under the drive of the second swing arm, thereby triggering the unlocking mechanism to unlock the car door.
[0018] In some embodiments, one of the unlocking member and the second swing arm is provided with a push rod, and the other is provided with a first guide groove through which the push rod passes. During the process of the handle switching from the extended state to the unlocked state, the push rod moves under the action of the second swing arm, thereby driving the unlocking member to rotate.
[0019] In some embodiments, the unlocking member is slidably disposed on the base, and during the process of the handle switching from the extended state to the unlocked state, the unlocking member slides under the drive of the second swing arm, thereby triggering the unlocking mechanism to unlock the door.
[0020] In some embodiments, one of the unlocking member and the base is provided with a second guide groove, and the other is provided with a guide portion that cooperates with the second guide groove.
[0021] In some embodiments, the unlocking element is coaxially disposed with the second swing arm.
[0022] In some embodiments, the first rotating joint has a first rotation center line, and the second rotating joint has a second rotation center line. On the same projection plane perpendicular to the length direction of the handle, the projection of the second rotation center line is located between the projection of the first rotation center line in the initial state and the projection of the first rotation center line in the extended state.
[0023] In some embodiments, on the same projection plane perpendicular to the length direction of the handle, the projection of the first rotation center line in the initial state is at the same position as the projection of the first rotation center line in the extended state.
[0024] In some embodiments, the drive member drives the push member to move along the length direction of the handle, thereby causing the handle to extend or retract.
[0025] According to a second aspect of this application, a vehicle door is provided, including a handle assembly provided in any embodiment of the first aspect.
[0026] According to a third aspect of this application, a vehicle is provided, including a handle assembly provided in any embodiment of the first aspect or a door provided in any embodiment of the second aspect.
[0027] In the handle assembly of this application embodiment, the drive mechanism is synchronously connected to the front and rear ends of the handle to achieve synchronous extension and retraction of the front and rear ends. In this way, the displacement of the front and rear ends in the extension and retraction direction of the handle is consistent, which not only effectively avoids deviation in the fit between the handle and the base, making the gap between the handle and the door uniform, ensuring normal handle operation, reducing the difficulty of opening the door, but also improves the aesthetics and overall texture of the vehicle appearance.

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0063] Reference Figures 1 to 15 According to a first aspect of this application, a handle assembly 100 is provided, the handle assembly including a base 10, a handle 40 and a drive mechanism 20, the handle 40 having an initial state and an extended state, the handle 40 being configured to retract into the base 10 in the initial state and extend out of the base 10 in the extended state, the handle 40 having a front end 41 and a rear end 42 along its length direction; the drive mechanism 20 is synchronously driven connected to the front end 41 and the rear end 42 to drive the front end 41 and the rear end 42 to extend and retract synchronously.
[0064] It's understandable that the handle is initially hidden inside the base, and extends out of the base when extended for the user to grip.
[0065] It can be understood that the front and rear ends are the opposite ends of the handle. The drive mechanism is connected to the front and rear ends through synchronous transmission, which allows the front and rear ends of the handle to extend and retract synchronously. Synchronous extension and retraction means that the front end 41 and the rear end 42 extend out of the base or retract into the base in the same direction at the same speed.
[0066] In this embodiment, the drive mechanism is synchronously connected to the front and rear ends of the handle, enabling synchronous extension and retraction of the front and rear ends. This ensures that the displacement of the front and rear ends in the extension and retraction direction of the handle remains consistent. This not only effectively prevents deviations in the fit between the handle and the base, ensuring a uniform gap between the handle and the door, guaranteeing normal handle operation, and reducing the difficulty of opening the door, but also enhances the aesthetics and overall quality of the vehicle's appearance.
[0067] In some embodiments, the base is embedded inside the vehicle door.
[0068] In some embodiments, the base is provided with a receiving groove facing outwards from the vehicle door. In the initial state, the handle is concealed within the receiving groove; in the extended state, the handle extends out of the receiving groove.
[0069] Reference Figure 3 In some embodiments, the drive mechanism 20 includes a drive member 21 and a push member 22. The push member 22 is movably disposed on the base 10. The drive member 21 is connected to the push member 22 in a transmission manner. The push member 22 is synchronously connected to the front end 41 and the rear end 42 in a transmission manner. The drive member 21 drives the push member 22 to move and cause the handle 40 to extend and retract.
[0070] The driving component can be a power component such as an electric motor, a cylinder, or a gas cylinder.
[0071] In some embodiments, the drive member 21 drives the push member 22 to move along the length direction of the handle 40, thereby causing the handle 40 to extend or retract. This arrangement can reduce the space occupied by the handle assembly in the thickness direction of the door.
[0072] Specifically, refer to Figure 6 and Figure 7 The base is provided with a guide boss, and the pusher is provided with a mating groove, with the guide boss embedded in the mating groove.
[0073] For example, the mating groove extends along the length of the handle.
[0074] For example, the pusher has mating grooves on both sides along the width direction of the handle (i.e., the height direction of the vehicle).
[0075] Reference Figure 2 and Figure 3 In some embodiments, the drive mechanism 20 further includes a first swing arm 23 and a second swing arm 24. One end of the first swing arm 23 is connected to the front end 41 to form a first rotating joint, and the other end is connected to the base 10 to form a second rotating joint. One end of the second swing arm 24 is connected to the rear end 42 to form a third rotating joint, and the other end is connected to the base 10 to form a fourth rotating joint. The pusher 22 is synchronously connected to the front end 41 and the rear end 42 through the first swing arm 23 and the second swing arm 24, respectively.
[0076] In this embodiment, the driving component drives the pushing component to move, and the pushing component drives the first swing arm and the second swing arm to swing, so that the front end and the rear end of the handle move synchronously, thereby realizing the extension and retraction function of the handle.
[0077] The first swing arm can be connected to the base via the second pivot and to the front end of the handle via the third pivot.
[0078] The second swing arm can be connected to the base via the fourth pivot and to the rear end of the handle via the fifth pivot.
[0079] Reference Figure 14 and Figure 15 In some embodiments, the first revolute joint has a first rotation center line, the second revolute joint has a second rotation center line, the third revolute joint has a third rotation center line, and the fourth revolute joint has a fourth rotation center line. The line connecting the first and second rotation center lines is parallel to the line connecting the third and fourth rotation center lines, and the distance between the first and second rotation center lines is equal to the distance between the third and fourth rotation center lines. This configuration allows the front and rear ends of the handle to extend and retract synchronously, reducing the displacement deviation between the front and rear ends in the extension and retraction direction during the extension and retraction process.
[0080] in, Figure 14 and Figure 15 In the diagram, dashed lines are used to show the connection between the first and second rotation center lines, as well as the connection between the third and fourth rotation center lines.
[0081] Reference Figure 9 and Figure 15 In some embodiments, the second swing arm 24 includes a swing arm body 241 and a connecting rod 242. One end of the swing arm body 241 is connected to the base 10 to form a fourth rotating joint, and the other end is connected to the connecting rod 242 to form a fifth rotating joint. The end of the connecting rod 242 away from the swing arm body 241 is connected to the rear end 42 to form a third rotating joint.
[0082] When extended, pulling the rear end can extend it further, increasing its freedom of movement in the vehicle's width direction for easier gripping by the user.
[0083] The connecting rod can also be set to give the handle an unlocked state. When the handle switches from the extended state to the unlocked state, the rear end will extend further. This action of the rear end extending further can serve as an unlock signal for the vehicle, thereby unlocking the door.
[0084] Reference Figure 2 , Figure 3 , Figure 11 and Figure 15 In some embodiments, the connecting rod 242 is connected to the rear end 42 via a first pivot 25. The handle assembly 100 also includes a support 30, which is rotatably disposed on the swing arm body 241 and is configured to support the first pivot 25 during the extension and retraction of the handle 40.
[0085] It is understandable that during the extension and retraction of the handle 40, the support provides a fulcrum for the first pivot, so that the line connecting the first rotation center line and the second rotation center line, and the line connecting the third rotation center line and the fourth rotation center line remain parallel and of equal length.
[0086] In one example, the support has a guide surface that conforms to the first pivot, which abuts against the guide surface during the extension and retraction of the handle 40.
[0087] Reference Figure 9 In some embodiments, the second swing arm 24 is provided with a first limiting part 243, and the support member 30 abuts against the first limiting part 243 during the extension and retraction of the handle 40. By providing the first limiting part, the support member can stably support the first rotating shaft.
[0088] The first limiting part is located on the swing arm body.
[0089] In one example, a torsion spring is provided between the support member and the swing arm body, and the support member tends to abut against the first limiting part under the action of the torsion spring.
[0090] In some embodiments, the handle 40 has an emergency state, wherein the handle 40 is configured such that the front end 41 is pressed down and the rear end 42 is raised in the emergency state.
[0091] It is understandable that the handle does not require a driving component and can switch from the initial state to the emergency state under the action of external force, making it convenient for users to grasp the back of the handle and unlock the car door.
[0092] Reference Figure 6 and in conjunction with reference Figure 2 In some embodiments, the base 10 is provided with a second limiting part 12 in the initial state and emergency state shown. During the switching of the handle 40 between the initial state and the emergency state, the second limiting part 12 restricts the support member 30 from abutting against the first limiting part 243, so that a clearance channel is formed between the support member 30 and the first limiting part 243. The first rotating shaft 25 is located in the clearance channel during the switching of the handle 40 between the initial state and the emergency state.
[0093] It is understandable that in the initial state, the support member abuts against the second limiting part. During the process of switching the handle from the initial state to the emergency state, the first rotating shaft is inserted into the clearance channel formed between the support member and the first limiting part, and the rear end of the handle extends out.
[0094] In some embodiments, the pusher 22 is provided with a first guide ramp 221 and a second guide ramp 222, the first swing arm 23 is drivenly connected to the first guide ramp 221, and the second swing arm 24 is drivenly connected to the second guide ramp 222.
[0095] For example, the first swing arm abuts against the first guide ramp, and the second swing arm abuts against the second guide ramp. During the process of switching the handle from the initial state to the extended state, the abutment position of the first swing arm and the first guide ramp gradually rises, and the abutment position of the second swing arm and the second guide ramp gradually rises, thereby causing the handle to extend out of the base.
[0096] In some embodiments, the first guide ramp 221 includes a first ramp surface 2211 and a second ramp surface 2212. The slope of the first ramp surface 2211 is less than the slope of the second ramp surface 2212. During the process of switching the handle 40 from the initial state to the extended state, the first swing arm 23 first contacts the first ramp surface 2211 and then contacts the second ramp surface 2212.
[0097] In some embodiments, the second guide ramp 222 includes a third ramp surface 2221 and a fourth ramp surface 2222. The slope of the third ramp surface 2221 is less than the slope of the fourth ramp surface 2222. During the process of switching the handle 40 from the initial state to the extended state, the second swing arm 24 first contacts the third ramp surface 2221 and then contacts the fourth ramp surface 2222.
[0098] In low-temperature environments, the handle is easily frozen, making it difficult to extend from the base. By designing a first and / or third ramp 2221 with a smaller slope, a greater ice-breaking force can be provided to the first and / or second swing arms to break the ice layer, allowing the handle to extend. After the first swing arm contacts the second ramp 2212 with a smaller slope, it will contact the second ramp with a larger slope. After the second swing arm contacts the third ramp with a smaller slope, it will contact the fourth ramp with a larger slope, allowing the handle to extend quickly.
[0099] In this embodiment, a slope with a gentler gradient provides the handle with strong ice-breaking force, while a slope with a steeper gradient ensures the handle extends quickly after ice breaking, facilitating normal user operation. This design satisfies the ice-breaking requirements while avoiding excessive wear and tear on the equipment.
[0100] Reference Figure 8 In some embodiments, the first swing arm 23 is rolledly connected to the first guide ramp 221. This arrangement can reduce wear between the first swing arm and the pusher.
[0101] Specifically, the first swing arm is equipped with a first roller, which rolls in conjunction with the first guide ramp.
[0102] Reference Figure 10 In some embodiments, the second swing arm 24 is rolledly connected to the second guide ramp 222. This arrangement reduces wear between the second swing arm and the pusher.
[0103] Specifically, the second swing arm is equipped with a second roller, which rolls in conjunction with the second guide ramp.
[0104] In some embodiments, a torsion spring is provided between the first swing arm and the base, and the first swing arm abuts against the first guide ramp under the action of the torsion spring. During the extension of the handle, the torsion spring accumulates potential energy; during the retraction of the handle, the torsion spring drives the first swing arm to return to its original position.
[0105] In some embodiments, a torsion spring is provided between the second swing arm and the base, and the second swing arm abuts against the second guide ramp under the action of the torsion spring. During the extension of the handle, the torsion spring accumulates potential energy; during the retraction of the handle, the torsion spring drives the second swing arm to return to its original position.
[0106] Reference Figure 12 and Figure 13 In some embodiments, the handle 40 also has an unlocked state. The handle assembly 100 also includes an unlocking member 50, which is connected to the base 10. During the process of the handle 40 switching from the extended state to the unlocked state, the unlocking member 50 moves under the drive of the second swing arm 24 and triggers the unlocking mechanism to unlock the door 200.
[0107] In one example, the unlocking element is connected to the unlocking mechanism of the car door via an unlocking cable. During the process of the handle 40 switching from the extended state to the unlocked state, the second swing arm 24 swings to drive the unlocking cable to trigger the unlocking mechanism to unlock the car door 200.
[0108] In another example, the handle assembly also includes a micro switch electrically connected to the vehicle's control system and unlocking mechanism. During the process of the handle 40 switching from the extended state to the unlocked state, the second swing arm 24 swings to drive the unlocking line to contact the micro switch. The control system responds to the contact signal between the unlocking element and the micro switch to control the micro switch to conduct the unlocking mechanism, thereby unlocking the door.
[0109] Reference Figures 1 to 15 In some embodiments, the unlocking member 50 is rotatably disposed on the base 10. During the process of the handle 40 switching from the extended state to the unlocked state, the unlocking member 50 rotates under the drive of the second swing arm 24, thereby triggering the unlocking mechanism to unlock the car door 200.
[0110] Understandable. Figures 1 to 15 In the embodiment shown, the unlocking element unlocks the car door by rotating to trigger the unlocking mechanism.
[0111] Reference Figure 10 and Figure 12 In some embodiments, one of the unlocking member 50 and the second swing arm 24 is provided with a push rod 244, and the other is provided with a first guide groove 51 through which the push rod 244 passes. During the process of the handle 40 switching from the extended state to the unlocked state, the push rod 244 moves under the action of the second swing arm 24, thereby driving the unlocking member 50 to rotate.
[0112] For example, the second swing arm is provided with a push rod, and the unlocking component is provided with a first guide groove, which is waist-shaped. In the initial state, the push rod is located at the bottom of the first guide groove; during the process of switching the handle from the initial state to the extended state, the push rod moves from the bottom of the first guide groove to the top of the guide groove, and the position of the unlocking component remains unchanged during this process. During the process of switching the handle from the extended state to the unlocked state, the push rod pushes the unlocking component to rotate.
[0113] Reference Figure 5 In some embodiments, the base is also provided with a clearance groove corresponding to the push rod, and the push rod passes through the clearance groove.
[0114] In some embodiments, a torsion spring is provided between the unlocking member and the second swing arm. When the handle in the extended state is switched to the unlocked state under the action of an external force, the torsion spring accumulates potential energy; when the external force is removed, the second swing arm is reset under the action of the torsion spring, ensuring that the second swing arm resumes its transmission connection with the push member.
[0115] Reference Figures 16 to 22 In some embodiments, the unlocking member 50 is slidably disposed on the base 10. During the process of the handle 40 switching from the extended state to the unlocked state, the unlocking member 50 slides under the drive of the second swing arm 24, thereby triggering the unlocking mechanism to unlock the door 200.
[0116] and Figures 1 to 15 The difference between the embodiments shown is that, Figures 16 to 22 In the embodiment shown, the unlocking element unlocks the car door by sliding to trigger the unlocking mechanism.
[0117] Reference Figure 19 and Figure 20 In some embodiments, one of the unlocking member 50 and the base 10 is provided with a second guide groove 13, and the other is provided with a guide portion that cooperates with the second guide groove 13.
[0118] For example, the base is provided with a second guide groove, and the unlocking component is provided with a guide portion. This arrangement can reduce the impact of the groove on the structural strength of the unlocking component.
[0119] Reference Figure 3 and Figure 17 In some embodiments, the unlocking element 50 and the second swing arm 24 are coaxially arranged. This arrangement can reduce the force transmission path between the second swing arm and the unlocking element, avoiding the influence of force direction deviation or loss during transmission on the movement of the unlocking element, thereby enabling the second swing arm to accurately control the movement of the unlocking element.
[0120] For example, both the unlocking element and the second swing arm are connected to the base via a fourth pivot.
[0121] In some embodiments, the first rotating joint has a first rotation center line, and the second rotating joint has a second rotation center line. On the same projection plane perpendicular to the length direction of the handle 40, the projection of the second rotation center line is located between the projection of the first rotation center line in the initial state and the projection of the first rotation center line in the extended state.
[0122] Because the movement trajectory of the first centerline is an arc, the handle experiences a significant offset along its length during extension and retraction. This results in a large gap between the handle and the base after extension, making it easy for the user to see the internal structure of the base and degrading the user experience. The embodiments of this application, through the aforementioned design, can reduce the offset along the length of the handle during extension and retraction, thereby reducing the gap between the handle and the base after extension and improving the user experience.
[0123] In some embodiments, on the same projection plane perpendicular to the length direction of the handle 40, the projection position of the first rotation center line in the initial state is the same as the projection position of the first rotation center line in the extended state. This configuration can significantly reduce the offset in the length direction of the handle during extension and retraction.
[0124] For example, the second rotation center line is located on the midline of the line connecting the first rotation center line in the initial state and the first rotation center line in the extended state. The midpoint of the line connecting the first rotation center line in the initial state and the first rotation center line in the extended state is connected to the second rotation center line, and the resulting line is parallel to the length direction of the handle.
[0125] Exemplary description Figures 1 to 15 How the handle assembly shown works:
[0126] The handle has an initial state, an extended state, an unlocked state, and an emergency state. Its unlocking process involves two scenarios: the drive unit is energized and de-energized.
[0127] Unlocking process for driver components in power-on state:
[0128] Initial state - Extended state: In the initial state, the pusher moves forward along the length of the handle, causing the first and second swing arms to rotate, so that the handle extends from the base to the extended state.
[0129] Extended State - Unlocked State: In the extended state, pulling the rear end of the handle causes the second swing arm to rotate the unlocking component clockwise, triggering the unlocking mechanism to unlock the door. At this time, the handle enters the unlocked state.
[0130] Unlocked State - Extended State: After the external force is removed, the first swing arm, the second swing arm, and the unlocking component reset under the action of their respective torsion springs and contact the pusher through their respective rollers. The unlocking component rotates, and the handle returns to the extended state.
[0131] Extended State - Initial State: The driving component drives the pusher to move in the opposite direction, retracting the handle into the base and returning to the initial state.
[0132] Unlocking process during power failure:
[0133] Initial State - Emergency State: In the initial state where the drive unit is powered off, press the front end of the handle to make it sink down and the rear end to lift up, switching to the emergency state.
[0134] Emergency unlocking: In an emergency, pull the back of the handle, and the second swing arm will cause the unlocking component to rotate forward, triggering the unlocking mechanism to unlock the door.

[0138] Initial state - Extended state: In the initial state, the pusher moves forward along the length of the handle, causing the first and second swing arms to rotate, so that the handle extends from the base to the extended state.
[0139] Extended State - Unlocked State: In the extended state, pulling the rear end of the handle causes the second swing arm to move the unlocking component forward, triggering the unlocking mechanism to unlock the door. At this time, the handle enters the unlocked state.
[0140] Unlocked State - Extended State: After the external force is removed, the first swing arm, the second swing arm, and the unlocking component are reset under the action of their respective torsion springs and contact the pusher through their respective rollers. The unlocking component moves in the opposite direction, and the handle returns to the extended state.
[0141] Extended State - Initial State: The driving component drives the pusher to move in the opposite direction, retracting the handle into the base and returning to the initial state.
[0142] Unlocking process during power failure:
[0143] Initial State - Emergency State: In the initial state where the drive unit is powered off, press the front end of the handle to make it sink down and the rear end to lift up, switching to the emergency state.
[0144] Emergency unlocking: In an emergency, pull the back of the handle, and the second swing arm will move the unlocking component, triggering the unlocking mechanism to unlock the door.
