Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly to a flush-mounted door handle assembly. Background Art

[0002] The hidden automotive exterior door handle has advantages such as reducing wind resistance, reducing wind noise, and being aesthetically pleasing, which is more in line with the development of the automotive industry and is increasingly favored by users.

[0003] For example, a hidden automotive exterior door handle in the prior art has a link mechanism arranged inside it. The link mechanism is connected to both ends of the handle body and is driven by an actuator to move the link mechanism, thereby enabling the handle body to protrude from the hidden position. However, this hidden handle has the following defects:

[0004] The actuator only drives the handle body to move to the open position. After that, the actuator returns to its original position and loses transmission with the handle body, or the handle body is supported by an extension part on the driving end of the actuator to maintain the open position. The reset of the handle body is only achieved by a torsion spring on it, and in the open position, the torsion spring is always in a state of resisting torsion. As a result, after long-term use, the reset function of the handle body may fail, or the handle body cannot fully return to the hidden state, that is, a part of the handle body is exposed outside the door, resulting in a gap between the handle body and the door, which may allow foreign objects to enter, affecting subsequent opening and reset actions. Moreover, the spatial planning of the internal structure of the handle base in the prior art is not good, which is not conducive to assembly. Especially for the additional inertia locking and mechanical opening structures of the handle body, corresponding inertia arms and mechanical opening structures need to be arranged within the space of the link mechanism, which is likely to cause jamming with the link structure, and the components of the inertia arms and mechanical opening structures and the link structure occupy the same space, further increasing the assembly difficulty. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a flush-mounted door handle assembly.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: A flush-mounted door handle assembly includes a handle base, a handle body supported within the handle base, and a driving mechanism for driving the handle body to move from a hidden position flush with the handle base to an open position protruding from the handle base. In the hidden position, the driving mechanism includes:

[0007] A first rotating arm having a shaft A received within the handle base and a shaft A1 received at the left end of the handle;

[0008] A second rotating arm having a shaft B received within the handle base and a shaft B1 received at the right end of the handle;

[0009] The driving wheel abuts on the left side of the first swing arm with respect to shaft A and applies a force for rotating shaft A1 towards the open position of the handle body.

[0010] The transmission rod has a first waist slot connected to the left side of the first swing arm with respect to shaft A, a shaft C2 connected to the left side of the second swing arm with respect to shaft B1, and a shaft C1 located at the right end of the first waist slot and connected to the first swing arm. The left end of the first waist slot is inclined upward.

[0011] The driving rod has a shaft D1 connected to the left side of the middle of the transmission rod and a shaft D2 located on the left side of the first swing arm. The shaft D2 is connected to the driving wheel and is located on the left side of shaft C1.

[0012] Starting from the hidden position as the initial point, the driving wheel has a divergent opening trajectory and a reset trajectory. Within the reset trajectory, as the driving wheel rotates, the shaft D2 moves relatively closer to or farther from the shaft D1 and reaches the relative stop point with the driving rod, so as to apply a force to the transmission rod and the handle body towards the hidden position.

[0013] Furthermore, a second waist slot for the shaft D2 to slide therein is provided at the left part of the driving rod. The second waist slot defines a first transmission section on the right side and a second transmission section on the left side with its center. Within the reset trajectory, the shaft D2 reaches the relative stop point in the second transmission section and pulls the transmission rod.

[0014] Within the opening trajectory, the shaft D2 slides along with the first transmission section and guides the second waist slot to swing obliquely upward to the right.

[0015] Furthermore, the first transmission section is inclined upward diagonally to the right of the center, the second transmission section is inclined downward diagonally to the left of the center, and the shaft D2 is placed within the first transmission section when the handle body is in the hidden position.

[0016] Furthermore, there is a dead zone between the shaft D2 and the right end of the first transmission section. The second waist slot is arranged parallel to the driving rod, and the shaft D1 is located within the extension of the second waist slot.

[0017] Furthermore, an arc-shaped abutting surface is provided on the driving wheel. The arc-shaped abutting surface extends eccentrically with respect to the center of the driving wheel. A bearing surface for abutting against the arc-shaped abutting surface is provided on the left side of the first swing arm. The bearing surface extends obliquely upward to the left.

[0018] Furthermore, a return torsion spring is provided on shafts A and B. The return torsion spring applies a force to the handle body towards the hidden position and applies a force for sliding the shaft C1 to the right end of the first waist slot. Optionally, the handle body is held in the hidden position by the return torsion spring.

[0019] Furthermore, a first unlocking device and a second unlocking device are provided at two axial ends of the second rotating arm. The first unlocking device is configured to be opened by an electrical signal, and the second unlocking device is configured to be opened by a mechanical action.

[0020] Furthermore, the first unlocking device includes a first unlocking arm arranged to extend at one axial end of the second rotating arm, and a signal switch assembly, the signal switch assembly includes a plurality of spring clips for triggering electrical signals, the spring clips extend sequentially in the same direction, and the first unlocking arm is provided with a plurality of triggering parts corresponding to the plurality of spring clips.

[0021] Furthermore, the second unlocking device includes a second unlocking arm rotatably arranged on the base, and a locking arm preventing the second unlocking arm from rotating in an opening direction, a pull wire assembly is arranged on the second unlocking arm, and the handle body is arranged to be pressed and tilted in an emergency state and further actuated relative to the pulling position to drive the second rotating arm to act on the second unlocking arm and force the second unlocking arm to overcome the blocking force of the locking arm, thereby driving the pull wire assembly.

[0022] Furthermore, an inertia arm is provided at the other circumferential end of the second rotating arm, a first locking point and a second locking point are provided on the second rotating arm, a locking portion is provided on the inertia arm, and the locking portion is separated from the rotation trajectory of the first locking point and the second locking point in a static position to allow the second rotating arm to rotate in the opening direction, and the locking portion rotates and engages with the first locking point under the action of inertia, or the locking portion and the second rotating arm rotate relative to each other under the action of inertia to enable the locking portion to engage with the second locking point. Furthermore, a wiring harness is also led out of the handle body, the wiring harness is connected to the electrical components in the handle body, and the wiring harness is received from the leading direction to the first rotating arm, the first rotating arm is also provided with an embedding groove for accommodating the wiring harness, and a connection portion for connecting the end of the wiring harness is provided on the handle base.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] The present invention provides a first transmission section and a second transmission section on the driving rod. When the handle body moves normally from the hidden position to the open position, and when the handle body moves from the open position to the hidden position, the shaft D2 and the shaft D1 are always engaged between the driving wheel and the transmission rod, so that the driving rod assists and guides the movement of the transmission rod, thereby improving the stability of the movement of the handle body.

[0025] When the torsion spring reset function on the handle body fails, the vehicle computer detects the position of the handle body and controls the actuator to move further relative to the opening stroke. At this time, the shaft D2 is driven to the top of the rotation center of the driving wheel under the further rotation of the driving wheel, and guides the shaft D2 into the second transmission section. Thereafter, the driving wheel rotates toward the initial position corresponding to the hidden position of the handle body, and the shaft D2 presses the second transmission section downward. At this time, the shaft D1 is forced to tilt, thereby pulling the transmission rod back to the initial position. At this time, the handle body moves toward the hidden position, thereby ensuring that the handle body is reset in place. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0059] like Figures 1-9 As shown, a flat-out door handle assembly includes a handle base 2, a handle body 1 supported in the handle base 2, and a driving mechanism for driving the handle body 1 to move from a hidden position flush with the handle base 2 to an open position extending out of the handle base 2, wherein the handle body 1 also has an actuating position manually actuated in the open position, and an emergency open position that is lifted up by pressing and then pulled.

[0060] In the following, the lower direction corresponds to the direction of the door facing the user, the upper direction corresponds to the direction of the door facing inward, and the left direction and the right direction correspond to the front and rear directions of the door. The driving mechanism will be further explained based on the hidden position of the handle body 1, such as Figures 3 to 6 As shown, the driving mechanism includes:

[0061] The first rotating arm 3 has an axis A received in the handle base 2 and an axis A1 received at the left end of the handle;

[0062] The second rotating arm 11 has an axis B received in the handle base 2 and an axis B1 received at the right end of the handle;

[0063] The driving wheel 4 abuts against the first rotating arm 3 on the left side of the axis A, and exerts a force to rotate the axis A1 toward the open position of the handle body 1;

[0064] The transmission rod 5 has a first waist slot 5.1 connected to the first swivel arm 3 on the left side of the shaft A, a shaft C2 connected to the second swivel arm 11 above and on the left side of the shaft B1, and a shaft C1 located at the right end of the first waist slot 5.1 and connected to the first swivel arm 3. The left end of the first waist slot 5.1 is inclined upward to adapt to the rotation trajectory of the shaft C1 when the second swivel arm 11 rotates;

[0065] The drive rod 6 has a shaft D1 connected to the left side of the middle part of the transmission rod 5, a second waist slot 6.1 located on the left side of the first swivel arm 3, and a shaft D2 located on the right side of the second waist slot 6.1. The shaft D2 is connected to the drive wheel 4 and is located on the left side of the shaft C1;

[0066] The drive wheel 4 has a divergent opening trajectory and a reset trajectory with the hidden position as the starting point. Within the opening trajectory, the shaft D2 swings upward and to the right synchronously with the drive wheel, and at this time, the shaft D2 travels to the open position and guides the second waist slot 6.1 to deflect upward and to the right; within the reset trajectory, the shaft D2 moves relatively closer to or farther from the shaft D1 as the drive wheel 4 rotates and moves to the relative stop point of the drive rod 6 to apply a force to the transmission rod 5 and the handle body 1 towards the hidden position.

[0067] (Drive wheel 4)

[0068] For the drive wheel 4, the drive wheel 4 is provided with driving force by the actuator 14, and the central axis of the drive wheel 4, the shafts A and A1 on the first swivel arm 3, the shafts B and B1 on the second swivel arm 11, the shafts C1 and C2 on the transmission rod 5, and the shafts D1 and D2 on the drive rod 6 are all arranged with respect to the height direction of the vehicle door.

[0069] Specifically, the drive wheel 4 is an arc-shaped yaw extension member, which has an arc-shaped abutting surface 4.1 that can abut against the first swivel arm 3. The arc-shaped abutting surface 4.1 extends eccentrically with respect to the center of the drive wheel 4, and the radius of the arc-shaped abutting surface 4.1 gradually increases in its extension direction. Thus, the drive wheel 4 has an opening trajectory with the handle body 1 from the hidden position to the open position as the boundary, and a reset trajectory with the handle body 1 from the open position to the hidden position as the boundary.

[0070] For the first swivel arm 3 and the drive wheel 4, a bearing surface 3.7 that abuts against the arc-shaped abutting surface 4.1 is provided on the left side of the first swivel arm 3. The bearing surface 3.7 extends obliquely upward to the left, and the bearing surface 3.7 is arranged above and on the left side of the shaft A, and the shaft C1 is adjacent to the bottom of the bearing surface 3.7. Thus, within the opening trajectory of the drive wheel 4, the arc-shaped abutting surface 4.1 presses on the bearing surface 3.7, forcing the first swivel arm 3 to rotate.

[0071] It should be noted that for the handle body 1 from the hidden position to the open position and then from the open position to the hidden position, both the opening trajectory and the reset trajectory are limited within a circular rotation trajectory of the driving wheel 4.

[0072] As a further improvement to the handle body 1, a reset torsion spring 7 is provided on the shaft A and the shaft B, and the reset torsion spring 7 holds the handle body 1 in the hidden position and applies a force for the shaft C1 to slide to the right end of the first waist slot 5.1. In other words, the reset torsion spring 7 always applies a force to the driving mechanism towards the hidden position of the handle body 1.

[0073] Furthermore, in this way, the handle body 1 has a first reset process and a second reset process. For the first reset process, it can be reset under the action of the reset torsion spring 7 after the handle body 1 is operated. For the second reset process, it is preferably applicable when the reset torsion spring 7 loses force, resulting in the handle body 1 being unable to be reset or unable to be fully reset to the hidden position. At this time, the driving wheel 4 enters the reset trajectory, and a pulling force is applied to the left end stop of the second waist slot 6.1 through the shaft D2, driving the first rotating arm 3 and the second rotating arm 11 to return to the hidden position.

[0074] Among them, the start of the second reset process can be implemented by the first unlocking device 8 in the following text, or a sensor is set in the car door or the handle base 2 to detect the position of the handle body 1, and after it is determined that the actuator 14 has performed an operation of opening the handle body 1 and the handle body 1 is pulled by the user's hand to unlock the car door, and the vehicle is in a driving state, or in other cases where the user is unable to operate the handle body 1 and the handle body 1 is still in the open position.

[0075] Optionally, the second reset process can also be set to start after the handle body 1 in the open position has not been operated for a long time.

[0076] Furthermore, the first reset process corresponds reversely to the above-mentioned opening process of the handle body 1, and will not be elaborated here.

[0077] When the handle body 1 is automatically reset by the reset torsion spring 7, the lower end of the bearing surface 3.7 is located above the abutting part of the arc-shaped abutting surface 4.1, thereby avoiding the influence of the driving wheel 4 on the position of the first rotating arm 3 during the process of returning to the initial position. During this process, the first rotating arm 3 rotates towards the left around the shaft A and abuts against the arc-shaped abutting surface 4.1 in real time, while the arc-shaped abutting surface 4.1 rotates downward in real time, so that the first rotating arm 3 and the driving wheel 4 maintain a stable return movement.

[0078] It is worth mentioning that when the handle body 1 is set to the mode of automatically performing the reset trajectory, the reset torsion spring 7 is set to only apply the auxiliary force for the return of the handle body 1 and the stable force for the opening of the handle body 1, and cannot completely pull the handle body 1 back to the hidden position. In this mode, it is necessary for the driving wheel 4 to automatically perform the reset trajectory. The driving wheel 4 is preferably abutted against the bearing surface 3.7 to keep the handle body 1 in the open position. After the vehicle door is closed, the handle body 1 is automatically reset by the reset trajectory of the cam.

[0079] (Driving mechanism)

[0080] As Figure 3 shown, for the first swing arm 3, the cross-section of the first swing arm 3 is approximately an inverted V shape, and the V shape presented by the first swing arm 3 is inclined towards the left end of the handle body 1 on its right side, and a main structure occupying most of the area is formed in the left part of the first swing arm 3. Both the shaft A and the shaft C1 are arranged on the left side of the first swing arm 3. Among them, for the arrangement of the rotating shaft positions on the first swing arm 3, in the hidden position, the shaft A is located at the lower part of the first swing arm 3, the shaft A1 is located at the right end of the first swing arm 3, the shaft C1 is located above and to the left of the shaft A, and the shaft C1 is also located at the right end stop of the first waist slot 5.1. When the transmission rod 5 swings upwards and to the right within the opening trajectory of the driving wheel 4, it allows the lower side wall of the first waist slot 5.1 to apply an auxiliary acting force for rotating the shaft C1 to the right, so that the first swing arm 3 smoothly rotates around the shaft A and drives the shaft A1 to press against the left end of the handle body 1 to move towards the open position;

[0081] For the second swing arm 11, the cross-section of the second swing arm 11 is approximately an inverted U shape. The shaft B is located below and to the left of the second swing arm 11, the shaft B1 is located below and to the right of the second swing arm 11, and the shaft C2 on the transmission rod 5 is located above and to the left of the shaft B. When the transmission rod 5 swings upwards and to the right within the opening trajectory of the driving wheel 4, an acting force for rotating the second swing arm 11 around the shaft B is applied through the shaft C2, and the shaft B1 is driven to press against the right end of the handle body 1 to move towards the open position, thereby realizing the flat-out opening of the handle body 1.

[0082] Among them, at the connection part of the second swing arm 11 corresponding to the right end of the handle body 1, a groove parallel to the handle body itself is provided on the right end of the handle body. This groove allows the connection part of the second swing arm 11 to slide therein during the opening trajectory, actuation trajectory, and emergency opening trajectory to ensure the smoothness of the action.

[0083] For the transmission rod 5 and the drive rod 6, they are mainly connected by a shaft D1 located at the end of the drive rod 6. The shaft D1 is preferably arranged on the left side of the middle part of the transmission rod 5 and close to the upper boundary of the transmission rod 5. In this way, within the opening trajectory of the drive wheel 4, the drive rod 6 can be driven along by the shaft D1 on the transmission rod 5 and the shaft D2 on the drive wheel 4, or under the action of the shaft D2 on the drive wheel 4, the drive rod 6 can assist the transmission rod 5 to make a yawing motion upward to the right through the shaft D1.

[0084] The above-mentioned transmission function also benefits from the arrangement of the rotation shaft position on the left part of the second swing arm 11. Among them, D1 is arranged adjacent to the shaft A and the shaft C1, and is located above the left side of the shaft D2, the shaft C1 and the shaft A. The shaft C1 is arranged below the left side of the shaft D1, and the shaft A is located at the bottom of the left part of the second rotation shaft.

[0085] Furthermore, the shaft D2 is located below the right side of the rotation center of the drive wheel 4 and above the left side of the shaft C1.

[0086] As a further implementation manner of the cooperation between the drive wheel 4 and the drive rod 6, in the hidden position, the second waist slot 6.1 is located at the lower lower part of the arc-shaped abutting surface 4.1, and the second waist slot 6.1 is arranged obliquely upward to the right and points in the direction of the shaft D1.

[0087] Among them, the second waist slot 6.1 defines a first transmission section 6.2 on the right side and a second transmission section 6.3 on the left side with its center. The first transmission section 6.2 is arranged obliquely upward on the right side of the center, and the second transmission section 6.3 is arranged obliquely downward on the left side of the center. And the shaft D2 is placed within the first transmission section 6.2 and close to the right end of the first transmission section 6.2 in the hidden position of the handle body 1.

[0088] Preferably, the second waist slot 6.1 is arranged on the left side of the shaft C1, and the right end of the first transmission section 6.2 is arranged adjacent to the shaft C1.

[0089] As a further implementation manner of the cooperation between the transmission rod 5 and the first swing arm 3, in the hidden position, the first waist slot 5.1 extends obliquely upward to the left, and the shaft C1 is located at the right end of the first waist slot 5.1. Through this connection method, when the transmission rod 5 makes the opening movement of the handle body 1, a guiding force is exerted on the opening movement of the first swing arm 3, restricting the first swing arm 3 to move along a specified trajectory, which is beneficial to the stability of the opening process of the handle body 1 and opening under the frozen state. At the same time, the first waist slot 5.1 is arranged in this direction to give space for the shaft C1 on the transmission rod 5 to move adaptively within the first waist slot 5.1 driven by the further rotation of the second swing arm 11 when the handle body 1 is in the opening position and the user pulls the handle to unlock.

[0090] (Opening trajectory)

[0091] Such asFigures 4 to 6 As shown, in this embodiment, a further explanation is made for the right-lower yawing action of the transmission rod 5 in the opening trajectory of the driving wheel 4. It should be noted here that by controlling the eccentric radius of the driving wheel 4, the inclination angle of the bearing surface 3.7, and the initial distance between the arc-shaped abutting surface 4.1 and the bearing surface 3.7, the first rotating arm 3 can quickly respond to the action of the driving wheel 4.

[0092] In the opening trajectory of the driving wheel 4, the handle body 1 moves from Figure 4 the position in Figure 5 to the position in

[0093] The arc-shaped abutting surface 4.1 presses against the bearing surface 3.7, forcing the first rotating arm 3 to rotate around the axis A. The first rotating arm 3 can quickly respond, and the axis C1 synchronously pulls the right end of the first waist slot 5.1, applying a right-side yawing force to the transmission rod 5. At this time, the transmission rod 5 pulls the driving rod 6 to move to the right following it through the axis D1;

[0094] While the transmission rod 5 pulls the driving rod 6, as the driving wheel 4 drives the axis D2 to rotate, the axis D2 drives the second waist slot 6.1 to yaw upward and to the right. At the same time, furthermore, the lower boundary of the first waist slot 5.1 applies an upward and right-side rotational force to the axis C1, driving the handle body 1 to tend to move towards the open position;

[0095] As the transmission rod 5 yaws upward and to the right, the axis D2 rotates upward with the driving wheel 4, causing the axis D2 to gradually move towards the second transmission section 6.3 on the left side;

[0096] When the handle body 1 reaches the stop point of the open position, the first rotating arm 3 rotates around the axis A, and the bearing surface 3.7 is driven to the right side of the axis A. At this time, the axis C1 is located directly above the axis A and remains at the right end stop point of the first waist slot 5.1. The first waist slot 5.1 still maintains an upward and leftward inclined posture to meet the movement space for the first rotating arm 3 to rotate to the left in response to the pulling of the handle body 1 when the user pulls the handle body 1; the axis D1 and the axis D2 are in the upper right side relative to the initial position, and the second waist slot 6.1 is in a posture approaching parallel to the transmission rod 5.

[0097] Preferably, in the hidden position, the axis C2 is located above the axis C1, positioning the transmission rod 5 in an obliquely upward and right-side posture. In this way, it is beneficial for the first rotation to drive the transmission rod 5, making the transmission rod 5 closer to the tangent of the radius circle of the axis B and the axis C2, and then driving the second rotating arm 11 to rotate around the axis B by the axis C2.

[0098] Optionally, as the driving wheel 4 moves along its opening trajectory and the lower right part of the shaft D1 on the transmission rod 5 yaws, the shaft D2 moves to the right end of the first transmission section 6.2 and applies a force to yaw the driving rod 6 to the right.

[0099] Specifically, based on the embodiment where the first swing arm 3 responds quickly, there is a dead zone between the shaft D2 and the right end of the first transmission section 6.2. The second waist slot 6.1 is arranged parallel to the driving rod 6, and the shaft D1 is located within the extension of the second waist slot 6.1. The purpose is to improve the followability of the left part of the driving rod 6 during the opening trajectory, so as to prevent the driving rod 6 from rotating excessively under the action of the shaft D2, which may affect the position of the transmission rod 5 too much and cause the first swing arm 3, the second swing arm 11, and the handle body 1 to be stuck with the car door opening.

[0100] In some other embodiments of the present invention, as a feasible solution for the transmission rod 5 to yaw downward to the right during the opening trajectory of the driving wheel 4, it should be noted that by controlling the eccentric radius of the driving wheel 4, the inclination angle of the bearing surface 3.7, and the initial distance between the arc-shaped abutting surface 4.1 and the bearing surface 3.7, the driving rod 6 responds to the force of the driving wheel 4 prior to the first swing arm 3. Specifically, this can be achieved by increasing the initial distance between the arc-shaped abutting surface 4.1 and the bearing surface 3.7, or relatively reducing the slope of the bearing surface 3.7, or setting a dead zone between the shaft C1 and the right end of the first waist slot 5.1 in the hidden position to reduce the response speed of the first swing arm 3 to the transmission rod 5.

[0101] During the opening trajectory of the driving wheel 4, the difference from the above actions is as follows:

[0102] During the process of the driving wheel 4 rotating upward to the right, an upward pressing force is applied to the driving rod 6 through the shaft D2, and then a force to yaw the relatively lagging transmission rod 5 upward to the right is applied by the shaft D1, which assists and further drives the first swing arm 3 to open, thereby further increasing the turning torque. At this time, the shaft C1 on the first swing arm 3 has reached the right end stop of the first waist slot 5.1 and applies a force to yaw the transmission rod 5 upward to the right. Then, under the frozen condition, the first swing arm 3 can drive the left end of the handle body 1 to break the ice to meet the requirement of opening the handle body 1 in a harsh environment.

[0103] Specifically, as the driving wheel 4 drives the shaft D2 to rotate, the shaft D2 abuts against and drives the first transmission section 6.2, and the shaft D2 applies an upward yawing force to the upper boundary of the first transmission section 6.2. At this time, the left part of the driving rod 6 and the second waist slot 6.1 yaw upward, thereby assisting the transmission rod 5 to further yaw upward. Moreover, under the action of the rotating driving wheel 4 and its shaft D2, the whole driving rod 6 has a tendency to press to the right side, thereby applying a force to the transmission rod 5 that rotates and yaws upward from the upper right side. Furthermore, the lower boundary of the first waist slot 5.1 applies an upward and rightward rotating guiding force to the shaft C1, driving the handle body 1 to move toward the open position.

[0104] As can be seen from the above process of opening the handle body 1, during the opening trajectory movement of the driving wheel 4, the driving rod 6 applies an auxiliary opening force to the transmission rod 5, which is beneficial to the opening actions of the first rotating arm 3 and the second rotating arm 11, so as to increase the torque of the handle body 1 and the driving mechanism toward the open position.

[0105] Based on the above embodiment of the rapid response of the first rotating arm 3, under the reset trajectory, the handle body 1 moves from the Figure 5 position in Figure 6 to the

[0106] The driving wheel 4 rotates away, starting to rotate downward to the left. The shaft D2 moves accordingly and slides to the second transmission section 6.3. At this time, due to the loss of force of the torsion spring, the distance between the shaft D1 and the shaft D2 is stretched. And in the case where the torsion spring has a certain rotational force, the difference is only the difference in the effective time when the distance is stretched;

[0107] As the shaft D2 further rotates and slides within the second transmission section 6.3 and finally reaches the left end stop of the second transmission section 6.3, at this time, the driving wheel 4 rotates further in the reverse direction relative to the hidden position, thereby pulling the driving rod 6 through the shaft D2, and then pulling the transmission rod 5 to yaw downward to the left through the shaft D1. At this time, the transmission rod 5 pulls the first rotating arm 3 and the second rotating arm 11 to move synchronously through the shaft C1 and the shaft C2 until the first rotating arm 3 and the second rotating arm 11 return to the initial position and the handle body 1 returns to the hidden position; during this process, the arc-shaped abutting surface 4.1 has separated from the bearing surface 3.7, and the driving wheel 4 rotates upward to the right again, that is, returns to the initial point of the opening trajectory. At this time, the shaft D2 slides to the initial port of the first transmission section 6.2 accordingly, and the left part of the driving rod 6 and the second waist slot 6.1 perform follow-up actions around the shaft D2, so that the driving mechanism and the handle body 1 completely return to the hidden position.

[0108] Among them, thanks to the tendency of the bearing surface 3.7 to tilt upward to the left, when the driving wheel 4 returns from the end of the reset trajectory to the starting point of the opening trajectory, the arcuate abutment surface 4.1 does not exert force on the bearing surface 3.7, and when the driving wheel 4 reaches the starting point of the opening trajectory, the arcuate abutment surface 4.1 contacts the bearing surface 3.7.

[0109] Based on the above-mentioned embodiment of the priority response of the driving rod 6, it should be pointed out that, in the reset trajectory, the auxiliary effect of the driving rod 6 on the transmission rod 5 is realized by the first transmission section 6.2, and in the reset trajectory, the shaft D2 leaves the first transmission section 6.2, and after the driving wheel 4 completes the reset trajectory and returns to the initial point of the opening trajectory, the shaft D2 only enters the initial port of the first transmission section 6.2 from the second transmission section 6.3, that is, it is located at the right position of the center of the second waist groove 6.1. In this process and position, the driving rod 6 does not exert a force on the transmission rod 5, and the driving mechanism can be maintained in a stable and reliable hidden position.

[0110] As a feasible implementation of the driving wheel 4 and the bearing surface 3.7, in the open position, when the driving wheel 4 is ready to rotate in the opposite direction from the opening trajectory, the bearing surface 3.7 is inclined to the right with respect to the vertical plane, so that the portion below the center of the bearing surface 3.7 is supported under the arc-shaped abutment surface 4.1, and then when the driving wheel 4 performs the reset trajectory, the driving wheel 4 exerts a force on the first rotating arm 3 to rotate to the hidden position.

[0111] Furthermore, a stop rib corresponding to the end point of the reset track is provided on the housing of the actuator 14, and the end of the driving wheel 4 away from the arc-shaped abutment surface 4.1 is stopped by the stop rib, indicating that the reset track is completed.

[0112] It should be pointed out that any of the above-mentioned axes corresponds to the pin axis between its two connecting parts, and there is no limitation on the position of the extended base of the mutually connected parts.

[0113] like Figure 17As shown, as another embodiment of the drive rod 6, the drive rod 6 can be selected as a tension spring 16. The two ends of the tension spring 16 are respectively connected to the shaft D1 and the shaft D2. Thus, within the opening trajectory of the drive wheel 4, the tension spring 16 successively enters a relatively compressed pressing state and a relatively stretched pulling-back state. Preferably, when in the pressing state, the tension spring 16 applies a force in the opening direction to the transmission rod 5, and when in the stretched state, the tension spring 16 applies a force to the transmission rod 5 to move towards the hidden position. When the drive wheel 4 returns to its position and loses support from the bearing surface 3.7, on the basis of the return torsion spring 7, the tension spring 16 assists the transmission rod 5 to return to its position, ensuring that the handle body 1 can return to the hidden position. Through the above improvements, the drive rod 6 is selected as the tension spring 16, thereby reducing the internal space occupation, and the tension spring 16 can apply a force in real time with the change of the distance between the shaft D1 and the shaft D2, thereby forcing the drive mechanism to remain in a state of mutual abutting transmission, reducing the gaps and play between the various components inside the drive mechanism, making the force transmission smoother, the two ends of the handle body 1 extending smoothly, reducing the bouncing of the two ends of the handle body 1, and further ensuring that the handle body 1 reaches the open position and the height of the handle body 1 extending relative to the vehicle door is consistent.

[0114] Optionally, a drive rod 6 with a second waist slot 6.1 can also be provided at one axial end of the first swivel arm 3 to connect the shaft D1 and the shaft D2, and a tension spring 16 is provided at the other axial end of the first swivel arm 3 to connect the shaft D1 and the shaft D2, thereby further optimizing the opening and hiding movement processes of the handle body 1. This method is achieved by providing two synchronously operating drive wheels 4 at the two axial ends of the actuator 14.

[0115] (Unlock device assembly)

[0116] As Figure 2 As shown, as a further improvement to the handle assembly, the unlocking operation of the handle body 1 is mainly realized by the second swivel arm 11. The first unlocking device 8 and the second unlocking device 9 are provided at the two axial ends of the second swivel arm 11. The first unlocking device 8 is set to be opened by an electrical signal, and the second unlocking device 9 is set to be opened by a mechanical action. By arranging the first unlocking device 8 and the second unlocking device 9 at the two ends of the shaft B of the second swivel arm 11, the space at both ends of the rotating shaft of the drive mechanism is reasonably utilized, making the internal structure of the handle base 2 more compact, so as to reduce the axial extension dimension of the handle base 2, facilitating the installation and assembly of the handle base 2 inside the vehicle door.

[0117] Optionally, through the above-mentioned first unlocking device 8 and second unlocking device 9, it can be selected to be triggered simultaneously when the handle body 1 rotates to the open position, so as to ensure that the handle body 1 is opened in place through the dual determination device, unlock the vehicle machine and the door. It can also be selected to trigger one of the unlocking devices, so that after it is determined that the handle body 1 is opened in place, the user can further rotate and open the handle body 1 to unlock the vehicle machine and the door.

[0118] In some other embodiments, the first unlocking device 8 is set to be electrically controlled for unlocking under normal conditions, and the second unlocking device is set to be enabled in an emergency state to unlock the door in a power-off state.

[0119] (First unlocking device 8)

[0120] As Figure 7 shown, as a further implementation manner of the first unlocking device 8, the first unlocking device 8 includes a first unlocking arm 8.1 arranged and extending at one axial end of the second rotating arm 11, and a signal switch assembly 8.6. The signal switch assembly 8.6 includes a plurality of elastic pieces 8.3 for triggering electric signals. The elastic pieces 8.3 extend in sequence in the same direction. A plurality of trigger parts 8.4 corresponding to the plurality of elastic pieces 8.3 are provided on the first unlocking arm 8.1. Among them, the plurality of trigger parts 8.4 are arranged at intervals in sequence in the opening direction of the second rotating arm, so as to trigger the elastic pieces 8.3 at different positions at different positions of the handle body.

[0121] Among them, the first unlocking device 8 has an installation housing 8.2. The installation housing 8.2 is constrained within the handle base 2. And the first unlocking arm 8.1 is an independent component. It has a shaft E1 arranged to rotate within the installation housing 8.2, and a shaft E2 engaged at one axial end of the second rotating arm 11. A driving groove 11.1 for driving the first unlocking arm 8.1 to act is provided at one axial end of the second rotating arm 11. And the contour within the driving groove 11.1 is provided with a gap for the shaft E2 to move in the rotating direction to prevent the first unlocking arm 8.1 from being stuck.

[0122] Specifically, the number of trigger parts 8.4 on the first unlocking arm 8.1 is three, the number of elastic pieces 8.3 is three, and the plurality of trigger parts 8.4 are all close to contact with the signal switch assembly 8.6 for quick response.

[0123] As a setting purpose of the elastic pieces, the purpose of setting a plurality of elastic pieces 8.3 and corresponding trigger parts 8.4 is to ensure that the vehicle machine is unlocked after the handle body 1 is opened in place.

[0124] As a setting purpose of the elastic piece, the elastic piece is set to detect the position and movement state of the handle body. Among them, the switch assembly has a first elastic piece, a second elastic piece and a third elastic piece. The first unlocking arm includes a first triggering part, a second triggering part and a third triggering part corresponding to the elastic piece. Among them, the first elastic piece and the first triggering part, the second elastic piece and the second triggering part, and the third elastic piece and the third triggering part are arranged into a first signal group 8.31, a second signal group 8.32, and a third signal group 8.33 with gradually increasing intervals, and the multiple signal groups are arranged from near to far as shown in Figure 7;

[0125] Optionally, multiple corresponding elastic pieces 8.3 and triggering parts 8.4 are arranged at intervals about axis B.

[0126] As an example, the first signal group 8.31 is the proximal elastic piece of the switch assembly. It approaches the triggering part 8.4 in the hidden position. One of the functions of this proximal elastic piece is to respond quickly to obtain the signal that the handle body 1 performs the opening action. The second function is to determine whether the handle body 1 returns to the in-place position. If the handle body 1 does not return to the in-place position, the proximal elastic piece is still in the triggered state of contacting the triggering part 8.4, and the opening signal always exists. At this time, the vehicle-mounted system can judge that the handle body 1 is in the state of not returning to the in-place position, and then the actuator 14 acts, so that the driving wheel 4 enters the reset track action, and then ensures that the handle body 1 is reset to the hidden position in place.

[0127] Further, the second signal group 8.32 and the third signal group 8.33 are the distal elastic pieces of the switch assembly. They keep a distance from the triggering part 8.4 in the hidden position, and the distal elastic piece is triggered only after the handle body 1 is opened in place, and the signal that the opening position of the handle body 1 is in place is obtained.

[0128] Optionally, after obtaining the signal that the opening position of the handle body 1 is in place, the vehicle door is electronically unlocked.

[0129] As an improved option, the third signal group 8.33 can also be set to be triggered after the handle body 1 is pulled by hand in the opened position. At this time, the handle body is pulled to the actuated position, and the third signal group 8.33 is triggered at this time to electronically unlock the vehicle door. In this embodiment, the second signal group 8.32 is used for signal transmission when the handle body 1 reaches the opened position.

[0130] In some other embodiments, an independent sensor can also be arranged in the installation shell 8.2 to detect the current positions of multiple triggering parts 8.4 on the first unlocking arm 8.1 to judge whether the second rotating arm 11 is opened in place.

[0131] As an implementation method of electrically unlocking the vehicle door through the handle body 1, an external capacitor is set on the outer surface of the handle body, and an internal capacitor is set on the inner surface of the handle body. The opening action of the handle body is triggered when a human hand touches the external capacitor, and the human hand further holds the handle body to touch the internal capacitor, thereby triggering the electrically controlled unlocking of the handle body.

[0132] Through the above improvements, it is only necessary to extend the first unlocking arm axially along the second rotating arm, and to arrange a plurality of spring components matching the extension length of the first unlocking arm on one side of the base, that is, the detection and electric unlocking of the open position, hidden position and actuating position of the handle body are implemented within the limited space on one side of the first rotating arm, and the first unlocking device is accommodated in the shell, which further facilitates assembly in a modular form.

[0133] (Second unlocking device 9)

[0134] like Figure 8 As shown in the handle body 9, as a further implementation of the second unlocking device 9, the second unlocking device includes a second unlocking arm 9.2 rotatably arranged on the base, and a locking arm 9.3 preventing the second unlocking arm 9.2 from rotating in the opening direction, a pull wire assembly is arranged on the second unlocking arm 9.2, and the handle body is arranged to be pressed and tilted in an emergency state and further actuated relative to the pulling position to drive the second rotating arm to act on the second unlocking arm 9.2 and force the second unlocking arm 9.2 to overcome the blocking force of the locking arm 9.3, thereby driving the pull wire assembly, whereby, in an emergency state, one end of the handle body corresponding to the second rotating arm is defined as a tilted end.

[0135] Specifically, a pressure portion 11.1 acting on the second unlocking arm 9.2 is formed on the second rotating arm, and a first transmission portion 9.21 is provided on the second unlocking arm 9.2 within the rotation range of the pressure portion 11.1. In an emergency position, the handle body is further pulled by hand so that the pressure portion 11.1 acts on the first transmission portion 9.21 and forces the second unlocking arm 9.2 to rotate, thereby driving the pull wire assembly to achieve mechanical unlocking.

[0136] The pressure-applying portion 11.1 has a first stroke from the concealed position to the open position, a second stroke from the open position to the actuated position, and a third stroke from the actuated position to the emergency open position.

[0137] In the first stroke, the pressure-applying portion 11.1 contacts or approaches the first transmission portion 9.21, so that when the handle body moves to the open position, the second unlocking arm 9.2 is not driven to rotate.

[0138] In the second stroke, without mechanical unlocking, when performing electric control unlocking and normally pulling the handle body to the actuation position, the pressing part 11.1 acts on the first transmission part 9.21. At this time, the second unlocking arm 9.2 is allowed to be forced to rotate by an angle without causing the cable assembly to complete door unlocking, and the user obtains a normal feel when pulling the handle body; or, when pulling the handle body to the actuation position, the second unlocking arm 9.2 is driven to rotate simultaneously, thereby driving the cable assembly until the door is unlocked, so as to perform electric control and mechanical unlocking simultaneously. The above two implementation methods are realized by controlling the distance between the cable assembly and the rotation axis G of the second unlocking arm 9.2, and the distance between the first transmission part 9.21 and the rotation axis G of the second unlocking arm 9.2.

[0139] In the third stroke, at this time in an emergency state, pressing the handle body forces the upturned end to turn out, thereby pulling the handle body to further rotate the second rotating arm relative to the open position and the actuation position, so as to effectively act on the first transmission part 9.21 by the pressing part 11.1, and the cable assembly acts to completely unlock the door.

[0140] As a further improvement to the second unlocking device, the second unlocking device further includes a locking arm 9.3. The locking arm 9.3 is normally within the rotation stroke of the second unlocking arm 9.2 to prevent the second unlocking arm 9.2 from rotating when in the open position and the actuation position. The locking arm 9.3 has a rotation axis H, and torsion springs for maintaining the current position and applying resistance are provided on both the rotation axis G of the second unlocking arm 9.2 and the rotation axis H of the locking arm 9.3.

[0141] Specifically, a second transmission part 9.22 is provided on the second unlocking arm 9.2. By using the second transmission part 9.22 to stop against the locking arm 9.3, the resistance for preventing the second unlocking arm 9.2 from driving the cable assembly to unlock the door is applied in the above first and second strokes. In the third stroke, that is, in an emergency state, the user needs to apply sufficient force to drive the second unlocking arm 9.2 through the second rotating arm and further overcome the resistance of the locking arm 9.3 and its torsion spring to perform mechanical unlocking. Of course, the locking arm 9.3 can also directly block the first transmission part 9.21.

[0142] In this embodiment, to ensure the resistance of the locking arm 9.3, the distance from the cable assembly and the second transmission part 9.22 to the axis G of the second unlocking arm 9.2 is greater than the distance from the first transmission part 9.21 to the axis G of the second unlocking arm 9.2. And in order for the user to achieve mechanical unlocking in an emergency state, an inclined surface is formed on the transmission cooperation part between the second transmission part 9.22 and the locking arm 9.3. Of course, the inclined surface is arranged within the opening stroke of the second transmission part 9.22, and the user needs to apply sufficient force to force the second transmission part 9.22 to rotate the locking arm 9.3 and leave the inclined surface thereon.

[0143] Among them, the axis G of the second unlocking arm 9.2 is arranged in parallel with the axis H of the locking arm 9.3, and the axis G of the second unlocking arm 9.2 is arranged perpendicular to the axis B of the second rotating arm. This way is beneficial to the spatial layout.

[0144] In some other embodiments, an inertia arm 9.4 is rotatably provided at the circumferential other end of the second rotating arm. A first locking point 11.2 and a second locking point 11.3 are provided on the second rotating arm. A locking portion 9.41 is provided on the inertia arm 9.4. The inertia arm 9.4 has a rotating shaft F parallel to the rotating shaft B of the second rotating arm. A torsion spring for maintaining the current position is provided on the rotating shaft F. The locking portion 9.41 is used to prevent the second rotating arm from moving after the vehicle is impacted by inertial force. Specifically, through the rotation of the inertia arm 9.4, a locking fit is formed between the locking portion 9.41 and the first locking point 11.2 and the second locking point 11.3 to prevent the second rotating arm from moving.

[0145] Specifically, the first locking point 11.2 and the second locking point 11.3 are arranged in a notch shape and are provided at the axial end of the second rotating arm, preferably on the same side as the pressing portion 11.1. The locking portion 9.41 matches the contour of the notch, and the first locking point 11.2 is closer to the locking portion 9.41 than the second locking point 11.3 in the opening direction.

[0146] Under normal conditions, that is, in the static position when not impacted, the inertia arm 9.4 is away from the rotation trajectories of the first and second locking points 11.3 to allow the second rotating arm to rotate towards the opening direction; when the handle body is impacted in the hidden position, the inertia arm 9.4 rotates under inertia and engages with the first locking point 11.2, thereby preventing the second rotating arm from performing an opening action under the action of inertial force; when the handle body is in the open position, the first locking point 11.2 moves away from the locking portion 9.41 as the second rotating arm opens, and the second locking point 11.3 faces the locking portion 9.41 in the opening direction. When the handle body is impacted in the open position, the inertia arm 9.4 rotates under inertia and engages with the second locking point 11.3, thereby preventing the second rotating arm from performing an opening action under the action of inertial force, so as to ensure the safety of the vehicle door and the handle body when impacted.

[0147] In the above embodiment, the inertia arm 9.4 is constrained to the base and is only allowed to rotate towards the first locking point 11.2 and the second locking point 11.3.

[0148] As a further embodiment, when impacted, the inertia arm 9.4 also prevents the second unlocking arm 9.2 from rotating, wherein a mechanical stopping portion 9.42 is provided on the side of the inertia arm 9.4 away from the stopping portion 9.41, and the mechanical stopping portion 9.42 is arranged facing the second unlocking arm 9.2, and preferably, the inertia arm 9.4 is arranged between the second unlocking arm 9.2 and the second rotating arm to meet and optimize the spatial layout, and a matching portion 9.23 is provided on the second unlocking arm 9.2 facing the inertia arm 9.4, and the matching portion 9.23 has an opening trajectory with the opening action of the second unlocking arm 9.2, and when impact force is applied, the inertia arm 9.4 is forced to move so that the mechanical stopping portion 9.42 appears within the opening trajectory of the matching portion 9.23, thereby preventing the second unlocking arm 9.2 from moving.

[0149] Furthermore, when subjected to an excessive impact force, the second unlocking arm 9.2 is forced to rotate, and the second unlocking arm 9.2 is configured to exert a force through the convex portion thereon to further maintain the inertia arm 9.4 in the locked position with the second rotating arm.

[0150] The mechanical stop portion 9.42 has an L-shaped stepped mating surface facing the mating portion 9.23, and the end of the mating portion 9.23 on the opening trajectory facing the mechanical stop portion 9.42 is an arc-shaped pointed protrusion, so that when subjected to excessive impact force, the inertia arm 9.4 first rotates to the opening trajectory, and the rotation of the mating portion 9.23 can, to a certain extent, drive the inertia arm 9.4 further toward the first locking point 11.2 or the second locking point 11.3 through the stepped mating surface, thereby further ensuring safety when impacted.

[0151] Through the above improvement, the second unlocking arm 9.2 and the second rotating arm are prevented from opening when impacted by the independent inertia arm 9.4, thereby improving safety and space compactness.

[0152] In the above action, if the handle body 1 has not reached the open position, the presence or absence of signals from the first signal group 8.31, the second signal group 8.32 and the third signal group 8.33 can be used to judge and prompt that the handle body 1 has an abnormality, and the user can control and select through the vehicle system to force a reset action. If the handle body 1 is not reset to the hidden position, a reset action is forced to be performed to prevent foreign objects from being stuck and wind resistance and wind noise during driving.

[0153] It should be pointed out that when the vehicle is not started and driving, thanks to the transmission coordination between the drive wheel 4 and the first rotating arm 3, and the spatial layout of the unlocking device at the second rotating arm 11, the left end of the handle body 1 can be ensured to be partially opened for user operation, so that by pulling, the second rotating arm 11 is forced to move to achieve unlocking.

[0154] In the above embodiment, a counterweight is provided on one side of the second swivel arm close to the shaft C2 and away from the hinge end of the handle body. By arranging the counterweight on the second swivel arm, the feel of pulling the handle body is improved.

[0155] (Routing of the handle body 1)

[0156] In the present invention, by further defining the structure of the first swivel arm 3 to optimize the spatial arrangement inside the handle base 2, a wire harness 10 is also led out from the handle body 1. The wire harness 10 is connected to the electrical components inside the handle body 1, and the wire harness 10 is received from the leading-out direction into the first swivel arm 3. An embedding groove 3.1 for accommodating the wire harness 10 is also provided on the first swivel arm 3. A connecting part for connecting the end of the wire harness 10 is provided on the handle base 2, and the above-mentioned electrical components can be applied to the handle body 1 for receiving unfolding action signals, closing action signals, or door unlocking signals and vehicle head unit unlocking signals.

[0157] Specifically, the embedding groove 3.1 extends along the contour of the first swivel arm 3, and the embedding groove 3.1 extends from the front end to the rear end of the first swivel arm 3. In this way, the wire harness 10 can be constrained at any contour position inside the first swivel arm 3. By setting the length between the two leading-out positions of the wire harness 10, the constraint and release positions of the wire harness 10 inside the first swivel arm 3 are controlled to meet different assembly requirements.

[0158] In this embodiment, by providing the embedding groove 3.1 inside the first swivel arm 3, the wire harness 10 is embedded inside the first swivel arm 3 from the leading-out position, and an anti-disengagement block 13 is integrally formed in the embedding groove 3.1. When assembling the wire harness 10, only need to buckle the wire harness 10 into the embedding groove 3.1, and the anti-disengagement block 13 restricts the wire harness 10 from disengaging, so as to keep the wire harness 10 embedded inside the first swivel arm 3. There is no additional part assembly, the operation is simple, the structure of the first swivel arm 3 is optimized, and it is convenient for the first swivel arm 3 to be formed.

[0159] (Regarding the wire harness connecting part 12)

[0160] From Figure 10 and Figure 15 it can be seen that as a further improvement to the wire harness connecting part 12, a first lead part 8.5 is led out from the signal switch assembly 8.6 of the first unlocking device 8, and a second lead part 14.1 is led out from the actuator 14. Among them, the first lead part 8.5 and the second lead part 14.1 are gathered and led out from the wire harness connecting part 12 on the handle base 2. Of course, under the guidance of this embodiment, other electric control components can also be provided inside the handle base 2, and their lead parts are led out from the wire harness connecting part 12.

[0161] In this way, all the wire harnesses 10 in the handle assembly are led out through the wire harness connection part 12, and there is no need to set up individual wire connection ports in the handle base 2, which facilitates assembly.

[0162] Among them, the wire harness connection part 12 is arranged on one side of the handle base 2 where the actuator 14 is located. The first swivel arm 3 is located between the end of the handle body 1 and the actuator 14. For electronic components that deviate from the wire harness connection part 12, it is preferably arranged on the outside of the handle base 2 to avoid interference from the internal drive mechanism. To facilitate the lead arrangement of the above-mentioned electronic components, a channel 2.3 for the passage and arrangement of leads is provided on the peripheral side of the handle base 2, and the channel 2.3 extends to the wire harness connection part 12.

[0163] From Figure 9 and Figure 10 it can be seen that preferably, a plurality of blocking blocks 2.4 are arranged at intervals in the vertical position of the lead part on the channel 2.3, so that the channel 2.3 forms a zigzag in the vertical direction to fix the lead part, and this lead part can be used as the first lead part 8.5 led out from the first unlocking device 8.

[0164] Through the above improvements, a second unlocking arm, an inertia arm, and a locking arm arranged in an L-shaped arrangement are provided at the other axial end of the second swivel arm. On the premise of ensuring the inertial locking and mechanical opening of the handle body in the hidden and open positions, the occupied space of the second unlocking device is fully compressed.

[0165] (Regarding the lead-out part of the wire harness 10 at the end of the handle body 1)

[0166] As Figure 16 shown, as a further implementation manner of the connection between the first swivel arm 3 and the handle body 1, the handle body 1 is provided with a receiving seat 1.1 corresponding to the first swivel arm 3. The wire harness 10 is led out from the receiving seat 1.1. The rear end of the first swivel arm 3 is placed into the receiving seat 1.1 and connected to the handle body 1, so that the part of the wire harness 10 placed in the receiving seat 1.1 by the first swivel arm 3 constitutes guidance and connection.

[0167] Specifically, a partition 1.3 is provided in the middle of the receiving seat 1.1, thereby dividing the receiving seat 1.1 into an interspaced transmission part 1.11 and an electrical part 1.12. The rear end of the first swivel arm 3 is placed into the transmission part 1.11. The rear end of the first swivel arm 3 and the transmission part 1.11 are rotationally connected through a connecting pin shaft, that is, the shaft A1 is arranged at the transmission part 1.11. The wire harness 10 is led out from the electrical part 1.12. A notch 1.2 is provided between the transmission part 1.11 and the electrical part 1.12. The notch 1.2 is specifically formed on the partition 1.3. The notch 1.2 allows the wire harness 10 to swing in the vertical direction to reduce the load of the first swivel arm 3 and the handle body 1 in the open position.

[0168] Specifically, the receptacle 1.1 fixes the electrical components by potting. The potted part 15 is specifically located in the electrical part 1.12. In this way, the lead-out part of the wire harness 10 on the end of the handle body 1 is fixed by potting. Therefore, there is no need to set a connection part for the wire harness 10 on the handle body 1, which simplifies the structure of the handle body 1 and facilitates the molding of the handle body 1.

[0169] (Regarding the anti-disengagement of the wire harness 10 in the slot 3.1)

[0170] As Figures 12 to 15 shown, preferably, a wire harness holding area is provided on the first swivel arm 3 to clamp the wire harness 10 or restrict the wire harness 10 from disengaging from the first swivel arm 3 in the thickness direction of the vehicle door in a relatively tight manner. Of course, with the movement of the first swivel arm 3 and the handle body 1, the wire harness 10 is allowed to linearly move in the length direction of the wire harness holding area to avoid over-tightening of the wire harness 10.

[0171] During the actual assembly process, the wire harness 10 has a first section 10.1 that leads from the end of the handle body 1 to the entrance of the wire harness holding area. The wire harness 10 in this section is set to be connected in a non-taut posture. Thanks to the notch 1.2 in the receptacle 1.1, the wire harness 10 can obtain a margin for relaxation and contraction when the handle body 1 moves.

[0172] As Figure 14 shown, as a further implementation of the wire harness holding area, the slot 3.1 extending on the first swivel arm 3 constitutes the wire harness holding area. At least one anti-disengagement block 13 is provided in the wire harness holding area. The anti-disengagement block 13 has a first extension part 13.2 extending in the slot 3.1 in the thickness direction of the vehicle door, and a second extension part 13.3 extending out and blocking on the opening surface of the slot 3.1.

[0173] Among them, the first extension part 13.2 preferably extends at the boundary of the slot 3.1. An opening for the wire harness 10 to be buckled into is formed between the second extension part 13.3 and the other boundary of the slot 3.1. A limiting channel 3.5 for restricting the wire harness 10 from disengaging is formed between the second extension part 13.3 and the slot 3.1. Of course, the size of the opening can be controlled according to the actual size of the wire harness 10. Preferably, the wire harness 10 passes through the opening in a locally deformed posture, which is beneficial to the anti-disengagement effect of the wire harness 10.

[0174] Optionally, the ratio of the cross-sectional size between the second extension part 13.3 and the slot 3.1 is greater than 0.5.

[0175] Preferably, in order to facilitate the wire harness 10 to be buckled into the slot 3.1, a guiding inclined surface 13.1 is provided on the anti-disengagement block 13, and the guiding inclined surface 13.1 faces the slot 3.1.

[0176] In some embodiments, the anti - detachment block 13 protrudes from the end face of the first rotating arm 3, so that the first extension part 13.2 deforms locally during the process of the wire harness 10 being buckled into the embedding groove 3.1, optimizing the assembly operation; in other embodiments, the end face of the anti - detachment block 13 can also be set flush with the end face of the first rotating arm 3 to ensure that the wire harness 10 is completely embedded in the embedding groove 3.1.

[0177] (Regarding the first rotating arm 3 and the wire harness 10)

[0178] As Figures 12 to 15 shown, as a further implementation of the first rotating arm 3, a straight section 3.2 is provided in the middle of the first rotating arm 3. A first connecting section 3.3 extends from the front part of the first rotating arm 3, and a second connecting section 3.4 extends from the rear part of the first rotating arm 3. The straight section 3.2 is spaced apart from the handle base 2 through the first and second connecting sections 3.4. The first connecting section 3.3 extends and approaches the handle base 2, and the second connecting section 3.4 extends and is placed in the receiving seat 1.1 at the end of the handle body 1, so that the wire harness 10 can be guided in the thickness direction. Among them, the wire harness 10 extends to the wall surface of the base through the first connecting section 3.3, and forms anti - detachment and fixation through the limiting structure on the base wall surface, and then continues to extend to the wire harness connection part 12. The wire harness 10 extends between the receiving seat 1.1 and the wire harness holding area through the second connecting section 3.4.

[0179] Through the first connecting section 3.3 and the straight section 3.2 on the first rotating arm 3 above, the part of the wire harness 10 on the straight section 3.2 is defined as the second section 10.2, and the part of the wire harness 10 between the first connecting section 3.3 and the limiting structure is defined as the third section 10.3. The anti - detachment blocks 13 are at least arranged at both ends of the straight section 3.2. The two ends of the straight section 3.2 are respectively connected to the front end and the rear end of the first rotating arm 3, that is, the first section 10.1 and the third section 10.3 of the wire harness 10, so that the second section 10.2 of the wire harness 10 can be constrained within the first rotating arm 3 through the wire harness holding area, while the first section 10.1 and the third section 10.3 of the wire harness 10 can be set according to the actual length requirements. Thus, the loosening and tightening of the wire harness 10 during the opening process of the handle body 1 can also be realized through its first section 10.1 and third section 10.3, so as to avoid the wire harness 10 being overly tightened.

[0180] (Regarding the embedding groove 3.1 and the wire harness 10)

[0181] As Figure 12 and Figure 13 shown, in other embodiments, by restricting the posture of the wire harness 10 in the embedding groove 3.1 to further optimize the connection relationship between the wire harness 10 and the first rotating arm 3, the wire harness 10 is restricted to a posture of bending and transitioning along its arrangement direction at least at one place in the moving arm or the handle base 2.

[0182] Specifically, the slots 3.1 are arranged in a parallel offset manner in the vertical direction, and a corner section is formed between the offset slots 3.1. Since the wire harness 10 is led out from the end of the handle body 1 to the second connecting section 3.4, it is preferred to use the first connecting section 3.3 and the straight section 3.2 as the parallel offset sections to ensure the stability of the relative position relationship among the wire harness 10, the second connecting section 3.4, and the housing 1.1. Of course, thanks to the notch 1.2 in the housing 1.1, the wire harness 10 obtains a greater translation margin at the part led out from the handle body 1.

[0183] As a further explanation of the parallel offset slots 3.1, one of its purposes is to avoid the joint part of the actuator 14 and the first rotating arm 3 to ensure that the acting position of the actuator 14 on the first rotating arm 3 is located at its relatively middle part, ensuring the stability of the force on the first rotating arm 3; the second purpose is to force the third section 10.3 to apply a tendency for the second section 10.2 to be closely attached to the wall surface of the slot 3.1, further ensuring the stability of the wire harness 10 in the straight section 3.2; the third purpose is to reduce the crosstalk and movement of the wire harness 10 in the length direction of the straight section 3.2, so as to control the take-up and release margin of the wire harness 10 at the first section 10.1 and the third section 10.3.

[0184] In addition, thanks to the parallel offset first connecting section 3.3 and the straight section 3.2, a bending section 3.6 is formed between the first connecting section 3.3 and the straight section 3.2 to allow the connecting part between the second section 10.2 and the third section 10.3 of the wire harness 10 to move within the bending section 3.6, so that the wire harness 10 can adapt to the movement of the first rotating arm 3.

[0185] (Regarding the handle base 2 and the wire harness 10)

[0186] As Figure 10 shown, as a further implementation of the limiting structure on the handle base 2, a number of limiting blocks 2.1 are provided on the handle base 2. The limiting blocks 2.1 are arranged at intervals from the front end of the first rotating arm 3 to the connecting part. Among them, the structure of the limiting block 2.1 is basically the same as that of the anti - detachment block 13, and it extends on the wall surface of the handle base 2, thereby restricting the wire harness 10 on the wall surface of the handle base 2 to prevent the wire harness 10 from loosening arbitrarily within the handle base 2.

[0187] As an improvement, the limiting block 2.1 can be selected as an arc - shaped bending shape. An auxiliary limiting block 2.2 is arranged on one side of the limiting block 2.1. The auxiliary limiting block 2.2 stops on one side of the wire harness 10, and the limiting block 2.1 stops on the other side and the upper part of the wire harness 10.

[0188] Preferably, the limiting block 2.1 is also arranged with respect to the inner boundary contour of the handle base 2. In this way, the contour position of the actuator 14 inside the handle base 2 can be avoided. On the other hand, it also increases the multiple bends of the wire harness 10 constrained by the limiting structure, which is beneficial to improving the stability of the wire harness 10 inside the handle base 2.

[0189] As Figure 11 and Figure 14 shown, in some other embodiments, the handle base 2 is provided with a through hole 2.5 for the end of the return torsion spring 7 on the shaft A to extend into. The through hole 2.5 corresponds to the part of the wire harness 10 constrained on the handle base 2, so that the end of the torsion spring can apply a force to the wire harness 10 to further improve the constraint effect of the limiting structure on the wire harness 10.

[0190] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
