The transmission portion 303 of the handle body 102 is spaced apart from the swing arm 104 by a distance D. That is, in the initial position of the handle body 102, the transmission portion 303 of the handle body 102 is separated from the swing arm 104 without contacting, and contacts the swing arm 104 only after the transmission portion 303 of the handle body 102 moves a certain distance D toward the swing arm 104. At this time, the rocker arm 104 is at the rocker arm initial position, and the slider 103 is 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 by a certain angle in the first rotation direction R1 about the handle body shaft 131 as compared to the initial position of the handle body 102 shown in fig. 9A when viewed from the front side of the handle assembly 100. Thereby, the operation end 311 of the grip 301 is separated from the grip holder 101, and an operation space 901 is formed between the grip 301 and the grip holder 101. The operating space 901 facilitates the operator to grip the handle 301 for the subsequent second opening stage of operation. During the rotation of the handle body 102 in the first rotation direction R1, the transmission portion 303 on the back surface of the handle 301 gradually moves toward the swing arm 104. Specifically, as shown in fig. 10B, when viewed from the rear side of the handle assembly 100, the slider 103 moves the transmission portion 303 of the handle body 102 by a distance a in the first moving direction M1 in comparison with the initial position of the handle body 102 shown in fig. 9B under the driving of the motor 105. Since a ≧ D (i.e., the distance between the transmitting portion 303 of the handle body 102 and the swing arm 104 when the handle body 102 is in the initial position), the transmitting portion 303 of the handle body 102 is in contact with the swing arm 104 after the transmitting portion 303 of the handle body 102 has moved the distance a in the first moving direction M1. More specifically, when the handle body 102 reaches the first open position when a is D, the transmission portion 303 of the handle body 102 just reaches a position of contact with the swing arm 104, and at this time, the swing arm 104 remains at the swing arm initial position. When a > D, the transmission portion 303 of the handle body 102 reaches a position contacting the swing arm 104 in a case where the handle body 102 has not reached the first open position, and then the transmission portion 303 of the handle body 102 rotates the swing arm 104 away from the swing arm initial position in a process of continuing the rotation of the handle body 102 toward the first open position. That is, when a > D, the transmission portion 303 of the handle body 102 is kept separated from the swing arm 104 only during a part of the stroke during the rotation of the handle body 102 from the handle body initial position to the handle body first open position, while the transmission portion 303 of the handle body 102 is kept in contact with the swing arm 104 during the remaining stroke during the rotation of the handle body 102 from the handle body initial position to the handle body first open position. When the transmission part 303 of the hand body 102 reaches the contact position with the swing arm 104, the protrusion 329 on the transmission part 303 enters the arc-shaped concave groove 407 of the swing arm 104 and is located at the first end 471 (see fig. 4) of the arc-shaped concave groove 407. a. Fig. 9C and 10C show a second open position of the handle body 102 in which the door lock has been opened. As shown in fig. 9C, when the handle body 102 continues to rotate by a certain angle in the first rotation direction R1 around the handle body shaft 131 as compared with the first open position of the handle body 102 shown in fig. 9B as viewed from the front side of the handle assembly 100, the operating end 311 of the handgrip 301 reaches the farthest position with respect to the handle base 101. As shown in fig. 10C, the slider 103 and the motor 105 remain in the positions shown in fig. 10B as viewed from the rear side of the handle assembly 100, and as the handle body 102 continues to rotate about the handle body shaft 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 protrusion 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 swing arm 104 is located at the swing arm open position, the handle body 102 is located at the second open position, and the slider 103 is located at the slider operating position.

In the first opening stage, i.e., in 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 a certain angle by the motor 105. More specifically, when the operator needs to open the door lock, the operator touches the trigger key 143 on the handle body 102, the motor 105 is activated by receiving a corresponding signal, and the driving rod 1001 of the motor 105 moves linearly along the first moving direction M1, thereby pushing the slider 103 to move in the slider channel along the first moving direction M1 toward the swing arm 104. During the movement of the slider 103 in the first movement direction M1, the contact portion 507 of the slider 103 comes into contact with 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 through 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 comes into 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 the slider 103 is moved by the motor 105, so that the handle body 102 rotates about the handle body shaft 131 until the handle body 102 is rotated 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 slide 103 no longer moves. The torsional elasticity of the first torsion spring 108 needs to be overcome in the process that the slider 103 is driven by the motor 105 to push the handle body 102 to rotate toward the first open position. While the first torsion spring 108 is compressed as the handle body 102 rotates, accumulating a return biasing force. In this process, the swing arm 104 maintains the swing arm initial position (i.e., when a ═ D), so that the elastic force of the second torsion spring 109 remains unchanged, or the swing arm 104 rotates with the handle body 102 only within a small angular range (i.e., when a > D), so that the second torsion spring 109 increases a small torsional elastic force.

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

During the second opening stage, i.e., the process of the handle body 102 from the first opening position of the handle body 102 shown in fig. 9B and 10B to the second opening position of the handle body 102 shown in fig. 9C and 10C, the operator is required to manually rotate the handle body 102 outward. Specifically, when the handle body 102 reaches the first open position, the operating space 901 is already formed between the handle body 102 and the handle holder 101, and the operator can insert his hand into the operating space 901 and grip the operating end 311 of the handle 301. Subsequently, the operator applying a force to the handle 301 can continue to rotate the hand 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 protrusion 329 of the transmission portion 303 of the handle body 102 rotates in the first rotational direction R1, and the protrusion 329 slides within 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 the contact position with the rocker arm 104, the first end 471 is farther away from the handle body shaft 131 than the second end 472, and when the protrusion 329 slides from the first end 471 to the second end 472, the protrusion 329 applies a force to the actuating portion 403 of the rocker arm 104, so that the actuating portion 403 of the rocker arm 104 moves away from the handle body shaft 131 against the torsional elasticity of the second torsion spring 109. Since the rocker arm 104 is fixed to the handle holder 101 by the rocker shaft 132, the actuation portion 403 of the rocker arm 104 is forced to rotate the rocker arm 104 about the rocker shaft 132 in the third rotational direction R3, thereby enabling the rocker arm 104 to rotate from the rocker initial position to the rocker open position. Rotation of the rocker arm 104 moves the lock wire 104 to pull the locking 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 holder 101, so that the handle body 102 cannot be rotated further.

As can be seen from the above description, not only the torsional elastic force of the first torsion spring 108 but also the torsional elastic force provided by the second torsion spring 109 needs to be overcome during the process of the operator pulling the handle body 102 from the first open position to the second open position. During this process, both the first torsion spring 108 and the second torsion spring 109 are compressed, so that the return deflection force is accumulated, 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 swing 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 swing arm 104 in the second opening phase.

In the first return phase, the operator releases the handle 301 and the rocker arm 104 is rotated in a fourth rotational direction R4 opposite to the third rotational direction R3 by the return-biasing force of the second torsion spring 109. While the swing arm 104 is rotating, the actuating portion 403 of the swing 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 biasing force from the first torsion spring 108, which causes the handle body 102 to rotate in the 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 handle body 102 with the power required for the return in the process of returning the handle body 102 from the handle body second open position to the handle body first open position. Since the handle body 102 is restored to the handle body first open position, the transmission portion 303 of the handle body 102 is in contact with the slider 103, but the slider 103 is held in the slider working position by the power of the motor 105, thereby blocking the handle body 102 from further rotating. 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 the handle body 102 returns to the first handle body open position, the rocker arm 104 returns to the initial rocker arm position when a is equal to D, the transmission part 303 of the handle body 102 leaves the actuating part 403 of the rocker arm 104, or only contacts the actuating part 403 of the rocker arm 104, but the transmission part 303 of the handle body 102 is not pushed by the actuating part 403 of the rocker arm 104 any more; and a > D, the swing arm 104 has not yet returned to the swing arm initial 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 rod 1001, so as to move the slider 103 along 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 is subjected to the reset deflection force of the first torsion spring 108, and returns to the handle body initial position (i.e., the position shown in fig. 9A) along the second rotation direction R2, and the handle body 102 completes the reset process.

In the second opening phase of the handle body 102, it is generally required that the handle body 102 is subjected to a return means with a spring force having a value within a certain range (for example, within a range of about 10-25N when the swing arm 104 is not connected to the latch, and within a range of about 35-65N when the swing arm 104 is connected to the latch) in order to ensure the operator's operational comfort and reliability. However, if the handle body 102 is also subjected to the above range of elastic force in the first opening stage of the handle body 102, it may result in a reduction in durability of the motor. In the above-described embodiment of the present application, by providing two independent reset means, so that only one reset means' elastic force can be mainly received in the first opening stage of the handle body 102, the elastic force of the reset 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 performed conveniently by the manual operation of the operator even in the case where the motor is not operated or the motor is not provided.

Furthermore, if the rocker arm 104 remains stationary during the first opening phase, the latch tongue connected to the rocker arm 104 may be arranged in a fixed connection with the rocker arm, without causing problems with the latch tongue being pulled by mistake during the first opening phase.

In some embodiments, the external force required to be applied during the first opening phase is approximately 1/2 times the external force required during the second opening phase, i.e., 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 stage to the external force required in the second opening stage is in the range of 0.1 to 0.9, that is, the ratio of the elastic force provided by the first torsion spring 108 to the elastic force provided by the second torsion spring 109 is in the range of 1: 9 to 9: 1.

in some embodiments, the three directions of the handle body shaft 131, the rocker shaft 132, and 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 lockwire mount 429 of the rocker arm 104. In some embodiments, the transmission 303 of the handle body 102 is closer to the handle body axis 131 than the operating end 311 of the handgrip 301. Thereby, the handle assembly can be designed more compact.

In some embodiments, the damping device 110 is disposed between the handle body 102 and the handle base 101, so as to perform a damping function during the first and second reset phases of the handle body 102, avoid the handle body 102 from rotating too fast, and ensure the handle body 102 to rotate smoothly and uniformly during the reset process.

While only certain features of the application have been illustrated and described herein, 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.
