As shown in fig. 10A, the slider 103 is connected to the motor 105 through its motor connection 509 as seen from the rear side of the handle assembly 100, and the contact portion 507 of the slider 103 abuts against the inclined surface 323 of the transmission portion 303 of the handle body 102, or the contact portion 507 is close to the inclined surface 323 of the transmission portion 303 of the handle body 102 with a small distance from the inclined surface 323. A distance D is provided between the transmission portion 303 of the handle body 102 and the swing arm 104. That is, in the initial position of the handle body 102, the transmission portion 303 of the handle body 102 is separated from contact with the swing arm 104, and only after the transmission portion 303 of the handle body 102 moves toward the swing arm 104 by a certain distance D, it is in contact with the swing arm 104. At this time, the rocker 104 is located at the rocker initial position, and the slider 103 is located at the slider initial position.

Fig. 9B and 10B show a first open position of the handle body 102 in which the door lock is not opened. As shown in fig. 9B, the handle body 102 is rotated about the handle body shaft 131 by a certain angle in the first rotation direction R1, as compared to the initial position of the handle body 102 shown in fig. 9A, as seen from the front side of the handle assembly 100. Thus, the operation end 311 of the handle 301 is separated from the handle holder 101, and an operation space 901 is formed between the handle 301 and the handle holder 101. The operating space 901 facilitates the operator to hold the handle 301 for the subsequent second opening phase operation. During rotation of the handle body 102 in the first rotation direction R1, the transmission portion 303 of the back surface of the handgrip 301 gradually moves toward the rocker arm 104. Specifically, as shown in fig. 10B, when seen from the rear side of the handle assembly 100, the slider 103 is driven by the motor 105 to move the transmission portion 303 of the handle body 102 by a distance a along the first movement direction M1, compared to the initial position of the handle body 102 shown in fig. 9B. Since a.gtoreq.d (i.e., the distance between the transmission portion 303 of the handle body 102 and the rocker arm 104 when the handle body 102 is in the initial position), the transmission portion 303 of the handle body 102 is in contact with the rocker arm 104 after the transmission portion 303 of the handle body 102 has been moved a distance a along the first movement direction M1. More specifically, when a=d, the transmission portion 303 of the handle body 102 reaches just the position in contact with the rocker arm 104 when the handle body 102 reaches the first open position, at which time the rocker arm 104 remains in the rocker arm initial position. When a > D, in the case where the handle body 102 has not yet reached the first open position, the transmission portion 303 of the handle body 102 reaches a position in contact with the rocker arm 104, and in the course of subsequent continued rotation of the handle body 102 toward the first open position, the transmission portion 303 of the handle body 102 rotates the rocker arm 104 away from the rocker arm initial position. That is, when a > D, the transmission portion 303 of the handle body 102 remains separated from the rocker arm 104 only during a part of the stroke of the handle body 102 from the handle body initial position to the handle body first open position, and the transmission portion 303 of the handle body 102 remains in contact with the rocker arm 104 during the remaining stroke of the handle body 102 from the handle body initial position to the handle body first open position. When the transmission portion 303 of the hand body 102 reaches a position of contact with the swing arm 104, the protrusion 329 on the transmission portion 303 enters the arcuate recess 407 of the swing arm 104 and is located at a first end 471 (see fig. 4) of the arcuate recess 407. a. Fig. 9C and 10C show the second open position of the handle body 102 in which the door lock has been opened. As shown in fig. 9C, as seen from the front side of the handle assembly 100, the handle body 102 continues to rotate around the handle body shaft 131 by a certain angle in the first rotation direction R1, as compared with the first open position of the handle body 102 shown in fig. 9B, and the operation end 311 of the handle 301 reaches the farthest position with respect to the handle holder 101. As shown in fig. 10C, from the rear side of the handle assembly 100, the slider 103 and motor 105 remain in the position shown in fig. 10B, while as the handle body 102 continues to rotate about the handle body axis 131 in the first rotational direction R1, the handle body 102 rotates the swing arm 104 in the third rotational direction R3 to the swing arm open position, and the boss 329 of the handle body 102 reaches the second end 472 of the recess 407 of the swing arm 104 (see fig. 4). At this time, the rocker arm 104 is located at the rocker arm open position, the handle body 102 is located at the second open position, and the slider 103 is located at the slider work position.

In the first opening phase, i.e. the process of the handle body 102 from the initial position of the handle body 102 shown in fig. 9A and 10A to the first opening position of the handle body 102 shown in fig. 9B and 10B, the motor 105 needs to be started, and the handle body 102 is rotated outwards (i.e. in the first rotation direction R1) by the motor 105 by a certain angle. More specifically, when the operator needs to unlock the door lock, the operator touches the trigger key 143 on the handle body 102, and the motor 105 is started upon receiving a corresponding signal, and the driving lever 1001 of the motor 105 moves linearly along the first moving direction M1, thereby pushing the slider 103 to move in the slider channel toward the rocker 104 along the first moving direction M1. During the movement of the slider 103 along the first movement direction M1, the contact portion 507 of the slider 103 contacts the inclined surface 323 of the transmission portion 303 of the handle body 102. Since the handle body 102 is fixed to the handle base 101 by the handle body shaft 131, the linear motion of the slider 103 can be converted into the rotational motion of the handle body 102. Specifically, after the contact portion 507 of the slider 103 is in contact with the inclined surface 323 of the transmission portion 303 of the handle body 102, the slider 103 pushes the inclined surface 323 of the transmission portion 303 of the handle body 102 while being moved by the motor 105, so that the handle body 102 rotates about the handle body shaft 131 until the handle body 102 rotates to the first open position. At this point, the motor 105 stops, for example, upon receiving a signal from a sensor (not shown), and the slider 103 does not continue to move. In the course of the slider 103 being driven by the motor 105 to push the handle body 102 to rotate toward the first open position, the torsion spring force of the first torsion spring 108 needs to be overcome. And the first torsion spring 108 is compressed with the rotation of the handle body 102, thereby accumulating the return deflection force. During this process, the rocker arm 104 maintains the rocker arm initial position (i.e., when a=d), so that the elastic force of the second torsion spring 109 remains unchanged, or the rocker arm 104 rotates with the handle body 102 only in a small angular range (i.e., when a > D), so that the second torsion spring 109 increases a small torsion elastic force.

Thus, in the first opening phase, the power required for rotation of the handle body 102 about the handle body axis 131 is provided by the motor 105, and rotation of the handle body 102 does not rotate the swing arm 104 or only rotates the swing arm 104 through a small angular range, so that the motor 105 only needs to overcome the torsion spring force of the first torsion spring 108 mainly, and does not need to overcome the torsion spring force of the second torsion spring 109 or only overcomes the torsion spring force of the second torsion spring 109 during a part of the stroke of the first opening phase of the handle body 102.

In the second opening phase, i.e., the process of the handle body 102 from the first open position of the handle body 102 shown in fig. 9B and 10B to the second open position of the handle body 102 shown in fig. 9C and 10C, the operator is required to manually continue to rotate the handle body 102 outwardly. Specifically, when the handle body 102 reaches the first open position, an operating space 901 has been formed between the handle body 102 and the handle base 101, and an operator can insert his or her hand into the operating space 901 and grasp the operating end 311 of the handle 301. Subsequently, the operator applying a force to the handle 301 can continue to rotate the handle body 102 in the first rotational direction R1 until the second open position of the handle body 102 is reached. During continued rotation of the handle body 102 in the first rotational direction R1, the boss 329 of the transmission portion 303 of the handle body 102 rotates in the first rotational direction R1, and the boss 329 slides in the arcuate recess 407 of the rocker arm 104 to the second end 472 (see fig. 4). When the transmission portion 303 of the hand body 102 just reaches a position of contact with the rocker arm 104, the first end 471 is farther from the handle body shaft 131 than the second end 472, and when the boss 329 slides from the first end 471 to the second end 472, the boss 329 applies a force to the actuation portion 403 of the rocker arm 104, thereby overcoming the torsion spring force of the second torsion spring 109, so that the actuation portion 403 of the rocker arm 104 moves in a direction away from the handle body shaft 131. Since the rocker arm 104 is fixed to the handle base 101 by the rocker arm shaft 132, the actuation portion 403 of the rocker arm 104 is forced to rotate the rocker arm 104 about the rocker arm shaft 132 in the third rotational direction R3, thereby enabling the rocker arm 104 to rotate from the rocker arm initial position to the rocker arm open position. Rotation of the rocker arm 104 moves the locking wire 104 to pull the bolt to unlock. In the second open position, the transmission portion 303 of the handle body 102 abuts against the rear side of the handle base 101, so that the handle body 102 cannot continue to rotate.

As is apparent from the above description, in pulling the handle body 102 from the first open position to the second open position by the operator, it is necessary to overcome not only the torsion spring force of the first torsion spring 108 but also the torsion spring force provided by the second torsion spring 109. During this process, both the first torsion spring 108 and the second torsion spring 109 are compressed, thereby accumulating the return deflection force, while the slider 103 and the motor 105 remain unchanged in the positions shown in fig. 9B and 10B. In the second opening phase, the force required for the movement of the handle body 102 and the rocker arm 104 is provided by the operator, and the slider 103 and the motor 105 do not participate in the movement of the handle body 102 and the rocker arm 104 in the second opening phase.

In the first return phase, the operator releases the handle 301, and the swing arm 104 is rotated in the fourth rotation direction R4 opposite to the third rotation direction R3 by the return deflection force of the second torsion spring 109. At the same time as the rocker arm 104 rotates, the actuating portion 403 of the rocker arm 104 pushes the transmission portion 303 of the handle body 102, and at the same time, the handle body 102 is also subjected to a return deflection force from the first torsion spring 108, which causes the handle body 102 to rotate in a second rotational direction R2 opposite to the first rotational direction R1 until the handle body 102 returns to the handle body first open position (i.e., the position shown in fig. 10B). That is, the first torsion spring 108 and the second torsion spring 109 simultaneously provide the required power for the return of the handle body 102 during the return of the handle body 102 from the handle body second open position to the handle body first open position. Since the handle body 102 is returned to the handle body first open position, the transmission portion 303 of the handle body 102 is in contact with the slider 103, however the slider 103 is held in the slider operating position by the power of the motor 105, thereby blocking the continued rotation of the handle body 102. At this time, the return biasing force provided by the first torsion spring 108 is insufficient to overcome the blocking force of the motor 105 and the slider 103, so that the handle body 102 is maintained in the handle body first open position. When a=d, when the handle body 102 is returned to the handle body first open position, the rocker arm 104 is returned to the rocker arm initial position, the transmission portion 303 of the handle body 102 is separated from the actuation portion 403 of the rocker arm 104 or is in contact with only the actuation portion 403 of the rocker arm 104, but the transmission portion 303 of the handle body 102 is no longer subjected to the pushing force of the actuation portion 403 of the rocker arm 104; and a > D, the swing arm 104 has not yet been returned to the swing arm home position when the handle body 102 is returned to the handle body first open position.

In the second reset phase, the operator presses the trigger key 143, and the motor 105 receives a signal to retract the driving lever 1001, which moves the slider 103 in the second moving direction M2 opposite to the first moving direction M1, so that the slider 103 returns to the slider initial position (i.e., the position shown in fig. 10A). At the same time, the handle body 102 receives the restoring deflection force of the first torsion spring 108, returns to the initial position of the handle body (i.e., the position shown in fig. 9A) along the second rotation direction R2, and the handle body 102 completes the restoring process.

In the second opening phase of the handle body 102, it is generally required that the spring force of the resetting means to which the handle body 102 is subjected be within a certain range (for example, within a range of about 10-25N when the rocker arm 104 is not connected to the latch, and within a range of about 35-65N when the rocker arm 104 is connected to the latch) to ensure the operational comfort and reliability of the operator. However, if the handle body 102 is also subjected to the above-described range of elastic force in the first opening stage of the handle body 102, the durability of the motor may be reduced. In the above-described embodiment of the present application, by providing two independent resetting means, it is enabled to be mainly subjected to the elastic force of only one resetting means in the first opening stage of the handle body 102, the elastic force of the resetting means that needs to be overcome in the first opening stage of the handle body 102 is greatly reduced. Therefore, the load of the motor is reduced, and the service life of the motor is prolonged. Further, since the elastic force of the reset means to be overcome in the first opening stage of the handle body 102 is small, the operation of the first opening stage (i.e., the manual rotation of the handle body 102) can be performed manually by the operator, so that the first opening stage of the handle body 102 can be conveniently performed by the manual operation of the operator even in the case where the motor is disabled or not provided.

Furthermore, if the rocker arm 104 remains stationary during the first opening phase, the locking tongue connected to the rocker arm 104 may be provided in fixed connection with the rocker arm without causing a problem of mispulling the locking tongue during the first opening phase.

In some embodiments, the external force required to be applied in the first opening stage is approximately 1/2 of the external force required in the second opening stage, that is to say the spring forces provided by the first torsion spring 108 and the second torsion spring 109 are approximately equal. In some embodiments, the ratio of the external force required to be applied in the first opening phase to the external force required in the second opening phase is in the range of 0.1 to 0.9, that is to say the ratio of the spring force provided by the first torsion spring 108 to the spring force provided by the second torsion spring 109 is in the range of 1:9 to 9:1.

in some embodiments, the direction of extension of the handle body shaft 131, the direction of extension of the rocker shaft 132, and the direction of movement of the slider 103 are perpendicular to each other. In some embodiments, the actuation portion 403 of the rocker arm 104 is closer to the rocker shaft 132 than the wire lock mounting portion 429 of the rocker arm 104. In some embodiments, the transmission portion 303 of the handle body 102 is closer to the handle body shaft 131 than the operating end 311 of the handle 301. Thus, the handle assembly can be designed more compactly.

In some embodiments, by providing the damping device 110 between the handle body 102 and the handle base 101, damping can be achieved during the first and second reset phases of the handle body 102, avoiding too fast rotation of the handle body 102, and ensuring a smooth and uniform rotation of the handle body 102 during reset.

Although only a few features of the present application have been shown and described, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
