[0041]

[0013] The embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, in which the same or similar reference numerals throughout represent the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are merely used to explain the present application, and are not to be construed as limitations on the present application.

[0042] The following disclosure provides many different embodiments or examples for implementing the various structures of the present application. To simplify the disclosure of the present application, specific components and configurations are described below. Of course, these are examples only and are not intended to limit the present application. Furthermore, the present application may repeat reference signs and / or characters in various examples. This repetition is for the purposes of simplicity and clarity and does not inherently dictate a relationship between the various embodiments and / or configurations discussed. Furthermore, while the present application provides examples of various specific processes and materials, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0043] A transmission assembly 100 of a handle device 200 according to an embodiment of the present application will be described below with reference to the accompanying drawings. The transmission assembly 100 and a handle 2 are disposed within the handle device 200. The handle device 200 is mounted on a vehicle door body of a vehicle. A lock cylinder 101 is provided on the vehicle door body. A lock unit cooperating with the lock cylinder 101 is provided on the vehicle body. The lock cylinder 101 can cooperate with the lock unit to lock the vehicle door body after extension. For example, when the lock cylinder 101 retracts, the lock cylinder is disengaged from the lock unit, so that the vehicle door body can be opened. The door lock push rod 9 is movable at least to retract the lock cylinder 101. When the door lock push rod 9 moves to retract the lock cylinder 101, the lock cylinder 101 is unlocked, so that the vehicle door body can be opened. It should be noted that the lock cylinder 101 may be retracted or extended through the reciprocating motion of the door lock push rod 9, or the lock cylinder 101 may only be retracted through the movement of the door lock push rod 9. When the door lock push rod 9 moves away from the lock cylinder 101, the lock cylinder 101 may be extended through a reset spring.

[0044] As shown in FIGS. 4 to 8 , the transmission assembly 100 includes a base 1, a crankshaft 3, a first alignment member 31, a second alignment member 41, and an abutment member 5. The crankshaft 3 is rotatably disposed on the base 1. The output end of the crankshaft 3 is adapted to connect to a door lock push rod 9 and move the door lock push rod 9. The first alignment member 31 is disposed on the input end of the crankshaft 3. The first alignment member 31 rotates along the axial direction of the crankshaft 3 when the crankshaft 3 rotates. The second alignment member 41 is configured to rotate under the action of an external force. The second alignment member 41 is adapted to cooperate with the first alignment member 31 to rotate the first alignment member 31. The first alignment member 31 moves the door lock push rod 9 through the crankshaft 3 to perform unlocking. The abutment member 5 is disposed on the crankshaft 3 and rotates synchronously with the crankshaft 3. When the transmission assembly 100 is in the initial locked state, the abutment member 5 abuts against the base 1, and the abutment member 5 limits the rotation of the crankshaft 3, thereby ensuring that the first alignment member 31 is returned to its initial position when the transmission assembly 100 is returned to the initial locked state; that is, the position of the first alignment member 31 is returned to the position it was in when the transmission assembly 100 was in the initial locked state so that the first alignment member 31 is more accurately returned to its initial position under the action of a reset force to ensure accuracy in the next unlocking. For example, the second alignment member 41 is prevented from accidentally contacting the first alignment member 31 during the process of switching from the initial locked state to the unlocked state and pushing the first alignment member 31 around to perform unlocking, or from failing to unlock due to an insufficient movement distance of the first alignment member 31 when pushed by the second alignment member 41, thereby ensuring the reliability and accuracy of the unlocking performed by the transmission assembly 100.

[0045] Specifically, when the transmission assembly 100 is switched from the initial locked state to the unlocked state, the second alignment member 41 rotates toward the first alignment member 31 under the action of an external force, and the second alignment member 41 contacts the first alignment member 31 and rotates the first alignment member 31, so that the second alignment member 41 rotates the first alignment member 31 around the crankshaft 3, and the crankshaft 3 rotates together with the first alignment member 31 to move the door lock push rod 9, and the door lock push rod 9 pushes the lock cylinder 101 to retract, thereby unlocking the lock cylinder 101.

[0046] According to the handle device 200 provided in the embodiment of the present application, the abutment member 5 abuts against the base 1 to limit the rotation stroke of the crankshaft 3 so that the first alignment member 31 can be returned to its initial position after unlocking in preparation for the next unlocking, thereby preventing the handle device 200 from being unlocked prematurely or failing to unlock, and improving the reliability and accuracy of the unlocking performed by the transmission assembly 100.

[0047] 7, the transmission assembly 100 further includes a buffer member 11. The buffer member 11 is disposed on the base 1. When the handle 2 is in the initial lock state, the abutment member 5 abuts against the buffer member 11 to reduce the impact of a collision between the abutment member 5 and the base 1, which is beneficial to reduce noise generated when the abutment member 5 contacts the base 1, thereby reducing noise generated when the vehicle door body is unlocked and improving the user experience.

[0048] When the handle 2 is in the initial lock state, the abutment member 5 abuts against the buffer member 11 to limit the movement of the abutment member 5, thereby limiting the rotation of the crankshaft 3 and providing a circumferential limit for the crankshaft 3.

[0049] Furthermore, the base 1 is provided with an attachment groove. The buffer member 11 is attached within the attachment groove. For example, the attachment groove may extend through the thickness of the base 1, and the buffer member 11 is inserted into the attachment groove so that the buffer member 11 can be positioned and attached, preventing the buffer member 11 from being incorrectly positioned and failing to abut against the abutment member 5.

[0050] 5 and 8, the abutment member 5 includes a contact protruding rib 51. The abutment member 5 abuts against the base 1 through the abutment protruding rib 51 to reduce the contact area between the abutment member 5 and the base 1, thereby further reducing noise generated when the abutment member 5 contacts the base 1.

[0051] 5 and 8 , the abutment member 5 further includes a first limiting member 52. The first limiting member 52 is rotatably inserted into the base 1 to limit axial movement of the first limiting member 52 along the crankshaft 3, thereby providing an axial limit for the crankshaft 3 through cooperation between the first limiting member 52 and the base 1.

[0052] 8, a limiting groove 1b is formed in the base 1. A first limiting member 52 is rotatably inserted into the limiting groove 1b to limit axial movement of the crankshaft 3 along the crankshaft 3. In the initial locked state, the abutting protruding rib 51 of the abutting member 5 abuts against the buffer member 11 to limit circumferential rotation of the crankshaft 3 along the crankshaft 3.

[0053] The abutment member 5 abuts against the buffer member 11 arranged on the base 1, and at the same time, cooperates with the base 1 through the first limiting member 52 to provide circumferential and axial limits for the crankshaft 3, reducing the effect on the preset gap between the first alignment member 31 and the second alignment member 41 caused by movement of the crankshaft 3, ensuring that the gap between the first alignment member 31 and the second alignment member 41 does not change in the initial locking state, reducing the possibility of premature unlocking or unlocking failure of the lock cylinder 101 caused by changes in the gap between the first alignment member 31 and the second alignment member 41, and improving the reliability of the handle device 200.

[0054] In some embodiments, as shown in FIG. 5 , the transmission assembly 100 further includes a rotating arm 6. The rotating arm 6 is fixedly connected to one end of the crankshaft 3. The rotating arm 6 is adapted to rotatably cooperate with an input end of a door lock push rod 9. An output end of the door lock push rod 9 cooperates with a lock cylinder 101. The rotating arm 6 rotates to move the door lock push rod 9. The door lock push rod 9 moves to retract the lock cylinder 101 to unlock it.

[0055] 5, the crankshaft 3 and at least one of the rotating arm 6, the first alignment member 31, and the abutment member 5 are integral members (e.g., may be integrally molded members) so that the structural strength and stability of the crankshaft 3, the rotating arm 6, the first alignment member 31, and the abutment member 5 are increased, thereby improving the service life of the handle device 200. At the same time, the crankshaft 3, the rotating arm 6, the first alignment member 31, and the abutment member 5 are integral members so that the number of components of the handle device 200 is reduced and the structure of the handle device 200 is simplified, thereby improving the use reliability of the handle device 200 and allowing for simpler assembly of the handle device 200.

[0056] Optionally, the crankshaft 3, the rotating arm 6, the first alignment member 31, and the abutment member 5 are separate members.

[0057] In related art, a handle device drives a transmission assembly through the handle, which rotates a crankshaft and then pulls a tension wire (such as a Bowden cable) to unlock a vehicle door. However, the tension wire is a flexible power transmission element and generally includes two components: an inner multi-strand steel wire and a plastic sleeve wrapped around the steel wire. However, during the unlocking process, the steel wire moves and the plastic sleeve is a fixed member, resulting in a movement fit clearance between the steel wire and the plastic sleeve. When the vehicle is in a wet environment (such as rain or a car wash), the movement clearance of the tension wire may become wet or be affected by water intrusion. When the vehicle is in a low-temperature environment, the steel wire and plastic sleeve may freeze, preventing the unlocking function from being performed.

[0058] In the handle device 200 of the present application, the handle 2 cooperates with the rotating member 42, the rotating member 42 rotates the first alignment member 31 through the second alignment member 41 to rotate the crankshaft 3, and the crankshaft 3 drives the door lock push rod through the rotating arm 6 to unlock the vehicle door, thereby ensuring reliable and stable transmission through the transmission of mechanical components while avoiding the influence on the unlocking function of the handle device 200 caused by the vehicle being in a humid environment, a cold environment, or other environments, and thereby ensuring the reliability of the handle device 200.

[0059] 5, the handle device 200 further includes a first reset member 7. The first reset member 7 cooperates with the crankshaft 3 to reset the crankshaft 3 to the initial locked state. It can be understood that the first reset member 7 provides a reset force to the crankshaft 3 to reset the crankshaft 3 to the initial locked state, i.e., resets the position state of the crankshaft 3 to the position state of the crankshaft 3 in the initial locked state.

[0060] It can be seen that the first reset member 7 cooperates with the crankshaft 3 to apply a reset force to the crankshaft 3 so that the abutment member 5 abuts against the base 1 when the handle 2 is switched from the unlocked state to the pushed-out state, and the reset force tends to rotate the crankshaft 3. The crankshaft 3 rotates under the action of the reset force of the first reset member 7, causing the first alignment member 31 to return to its initial position, and at the same time, the abutment member 5 abuts against the base 1 to limit the rotation of the crankshaft 3, ensuring that the first alignment member 31 is accurately returned to its initial position in preparation for the next unlocking of the vehicle door body. The first alignment member 31 is in its initial position, i.e., a position where the second alignment member 41 does not apply a rotational force to the first alignment member 31, and in this case the abutment member 5 abuts against the base 1.

[0061] It may be understood that the crankshaft 3 may be reset to the initial locked state under the action of other external forces. For example, the lock cylinder 101 may be provided with a reset spring, which extends the lock cylinder 101 to move the door lock push rod 9 toward the base 1 after unlocking is completed, thereby resetting the crankshaft 3 to the initial locked state. Alternatively, the transmission assembly 100 may be further provided with a reset mechanism, which resets the crankshaft 3 to the initial locked state after unlocking is completed.

[0062] 5, the first reset member 7 is a torsion spring and is sleeved onto the crankshaft 3. The two ends of the first reset member 7 are fixed to the base 1 and the first alignment member 31, respectively, so that the first reset member 7 provides a reset torque for rotating the crankshaft 3 and causes the first alignment member 31 to return to its initial position, ensuring that the first alignment member 31 is returned to its initial position when the handle 2 is switched from the unlocked state to the pushed state. Furthermore, the torsion spring acts directly on the first alignment member 31, thereby ensuring reliable transmission of force.

[0063] 5 and 8, the two ends of the first reset member 7 are fixed to the base 1 and the first alignment member 31, respectively. When the handle 2 is switched from the unlocked state to the pushing state, the second alignment member 41 rotates toward a position away from the first alignment member 31. The first reset member 7 has a reset torque for rotating the crankshaft 3. The crankshaft 3 rotates the abutment member 5 until the abutment member 5 abuts the base 1. The abutment member 5 limits the rotation of the crankshaft 3. Therefore, after the handle 2 has completed the process of switching from the unlocked state to the pushing state, the first alignment member 31 can also be returned to its initial position in preparation for the next unlocking.

[0064] In some embodiments, as shown in FIGS. 6 and 7 , a handle device 200 includes a handle 2 disposed on a base 1. The transmission assembly 100 further includes a link assembly 43 and a rotating member 42. An input end of the link assembly 43 is adapted to connect the handle 2. The rotating member 42 is connected to an output end of the link assembly 43. A second alignment member 41 is disposed on the rotating member 42. The link assembly 43 cooperates with the handle 2 and the rotating member 42 separately to transmit the movement tendency of the handle 2 (e.g., the movement tendency to switch from the initial locked state to the unlocked state) to the rotating member 42 through the link assembly 43, thereby rotating the rotating member 42. As a result, the second alignment member 41 rotates together with the rotating member 42. Therefore, the second alignment member 41 pushes and rotates the first alignment member 31, thereby performing unlocking.

[0065] 4 , the second alignment member 41 includes a first portion 411 and a second portion 412, which define an angle therebetween. The first portion 411 is connected to the rotating member 42. During the unlocking process, the first portion 411 and the second portion 412 can both contact the first alignment member 31 to increase the contact area between the first alignment member 31 and the second alignment member 41. At the same time, the angle between the first portion 411 and the second portion 412 faces the first alignment member 31, thereby increasing the reliability and stability of the second alignment member 41 that rotates the first alignment member 31 and ensuring the reliability of the unlocking process.

[0066] In some embodiments, as shown in FIG. 7 , the transmission assembly 100 further includes a second reset member 8. The second reset member 8 cooperates separately with the base 1 and the link assembly 43. The second reset member 8 drives the link assembly 43 to rotate the handle 2 toward the pushed-out state. The link assembly 43 is driven through the reset torque of the second reset member 8 to return the handle 2 from the unlocked state to the pushed-out state, thereby automatically resetting the handle 2 after the vehicle door body is unlocked. Of course, it can be understood that the location for disposing the second reset member 8 is not limited thereto. For example, the second reset member 8 may instead act directly on the handle 2 to rotate the handle 2 from the unlocked state to the pushed-out state.

[0067] 7, the link assembly 43 includes a first link 431 and a second link 432. One end of the first link 431 rotatably cooperates with the handle 2, and the other end of the first link 431 rotatably cooperates with one end of the second link 432, the other end of which is sleeved onto the rotating member 42 to transmit the tendency of the handle 2 to move (e.g., switch from an initial locked state to an unlocked state) to the rotating member 42, so that the rotating member 42 rotates to rotate the second alignment member 41, and therefore the second alignment member 41 cooperates relatively with the first alignment member 41 to complete the unlocking.

[0068] 3 and 7, one end of the first link 431 is connected to one end of the handle 2 through a shaft pin, and the first link 431 rotatably cooperates with the handle 2. The other end of the first link 431 is connected to one end of the second link 432 through a shaft pin, and the first link 431 rotatably cooperates with the second link 432. The other end of the second link 432 is sleeved onto the rotating member 42 and rotates together with the rotating member 42. When the handle 2 is switched from the initial locked state to the unlocked state, the handle 2 moves the first link 431. The first link 431 rotates one end of the second link 432 toward the handle 2. The second link 432 rotates the rotating member 42 relative to the base 1, bringing the second alignment member 41 closer to the first alignment member 31. When the second alignment member 41 completes its idle stroke and is in contact with the first alignment member 31, the handle 2 continues to move in a direction away from the base 1. The second alignment member 41 rotates the first alignment member 31 around the crankshaft 3. The crankshaft 3 rotates together with the first alignment member 31 to move the door lock push rod 9. The door lock push rod 9 pushes the lock cylinder 101 back to unlock it.

[0069] 7, the second reset member 8 is a torsion spring. Two ends of the second reset member 8 are fixed to the base 1 and the second link 432, respectively, so that the second reset member 8 provides a reset torque for rotating the rotating member 42 and the link assembly 43 to return the handle 2 to the pushed-out state, and thus the handle 2 is automatically switched from the unlocked state to the pushed-out state in preparation for switching from the pushed-out state to the initial locked state.

[0070] For example, in the examples of FIGS. 6 and 7 , the second link 432 is provided with a slot structure 432a. The two ends of the second reset member 8 are fixed to the base 1 and the slot structure 432a, respectively. During the process of switching from the unlocked state to the initial locked state, the second reset member 8 has a reset torque to rotate the rotating member 42 and the second link 432. The second link 432 rotates to move the first link 431 toward the rotating member 42. The first link 431 rotates the handle 2 toward the base until the handle 2 returns to the initial locked state. In this case, the handle 2 is switched from the unlocked state to the initial locked state, and the second alignment member 41 rotates together with the rotating member 42. As a result, after the unlocking is completed, the second alignment member 41 automatically returns from the position of the second alignment member 41 when the handle 2 is in the unlocked state to the position of the second alignment member 41 when the handle 2 is in the initial locked state.

[0071] It should be noted that when the handle 2 is switched from the unlocked state to the initial locked state and the first alignment member 31 and the second alignment member 41 are returned from their positions in the unlocked state to their positions in the initial locked state, there is no interference between the first alignment member 31 and the second alignment member 41, and the relative movement between the first alignment member 31 and the second alignment member 41 is not affected.

[0072] It should be noted that the structure of the link assembly 43 is not limited thereto. For example, the link assembly 43 may be a three-link assembly, or may have an eccentric structure as long as the torque of the handle can be transmitted to the crankshaft 3.

[0073] A handle device according to one embodiment of the second aspect of the present application includes a handle 2 and a transmission assembly 100. The handle 2 is movably mounted on a base 1. The handle 2 moves so that the handle device 200 is switched between an initial locked state and an unlocked state. The transmission assembly 100 is the transmission assembly 100 provided in the above-described embodiment of the first aspect of the present application, and the handle 2 cooperates with a second alignment member 41 to rotate the second alignment member 41.

[0074] According to the handle device 200 provided in the embodiment of the present application, the use of the transmission assembly 100 described above increases the accuracy and reliability of the unlocking performed by the handle device 200.

[0075] In some embodiments, as shown in FIGS. 1 to 3 and 7 to 9, the base 1 is provided with a storage cavity 1a. The handle device 200 further has an extrusion state. In the initial lock state, the handle 2 is stored in the storage cavity 1a. The handle 2 is stored in the storage cavity 1a so as to be hidden within the storage cavity 1a. The upper surface of the handle 2 may be flush with the surface of the vehicle door body, lower than the surface of the vehicle door body, or slightly higher than the surface of the vehicle door body, which is beneficial for reducing airflow resistance when the vehicle is moving and improving the appearance of the vehicle. In the extrusion state and the unlocked state, at least a portion of the handle 2 is disposed outside the storage cavity 1a to facilitate user operation.

[0076] In the extruded state, the handle 2 may be parallel to the vehicle door body or may be positioned at an angle to the vehicle door body, which is understood to be not particularly limited in the present specification as long as at least a portion of the handle 2 is positioned outside the receiving cavity.

[0077] The handle 2 is movably arranged on the base 1 so as to switch between an initial lock state and a push-out state. For example, to facilitate user use, an automated device such as a drive motor for automatically switching the handle 2 from the initial lock state to the push-out state or automatically switching the handle 2 from the push-out state to the initial lock state may be arranged in the vehicle door body. For example, to facilitate user use, the handle 2 is rotatable relative to the base 1 so as to switch between the push-out state and an unlocked state. For example, when the handle 2 is in the push-out state, the user manually pulls the handle 2 to unlock the vehicle door.

[0078] In the initial lock state, a gap is provided between the first alignment member 31 and the second alignment member 41. After rotating by a preset gap from the initial lock state, the second alignment member 41 rotates the first alignment member 31. The first alignment member 31 moves the door lock push rod 9 through the crankshaft 3 to unlock the door.

[0079] Specifically, when the handle 2 is driven to switch from the initial locked state to the pushed-out state, the handle 2 cooperates with the connecting link assembly 43 to rotate the rotating member 42. The rotating member 42 rotates to rotate the second alignment member 41 toward the first alignment member 31. When the second alignment member 41 completes its idle stroke (the gap between the first alignment member 31 and the second alignment member 41), the second alignment member 41 contacts the first alignment member 31 to prepare for the unlocking process. When the handle 2 is driven to switch from the pushed-out state to the unlocked state, the handle 2 continues to cooperate with the link assembly 43 to rotate the rotating member 42. The rotating member 42 rotates to rotate the second alignment member 41 toward the first alignment member 31. In this case, the second alignment member 41 is in contact with the first alignment member 31. The second alignment member 41 rotates the first alignment member 31 around the crankshaft 3. The crankshaft 3 rotates together with the first alignment member 31 to move the door lock push rod 9. The door lock push rod 9 pushes the lock cylinder 101 back to unlock it.

[0080] A vehicle door according to an embodiment of the third aspect of the present application includes a vehicle door body, a handle device 200, a lock cylinder 101, and a door lock push rod 9. The handle device 200 is the handle device 200 provided in the embodiment of the second aspect of the present application. A base 1 is disposed on the vehicle door body. The lock cylinder 101 is disposed on the vehicle door body. A guide groove is provided in one of the lock cylinder 101 and the vehicle door body. An input end of the door lock push rod 9 is connected to a rotating arm 6, which is fixed and connected to a crankshaft 3. An output end of the door lock push rod 9 is disposed in the guide groove. When the output end of the door lock push rod 9 moves within the guide groove, at least the vehicle door can be unlocked.

[0081] According to the vehicle door provided in the embodiment of the present application, the reliability of unlocking the vehicle door is increased by using the handle device 200 described above.

[0082] A vehicle according to an embodiment of the fourth aspect of the present application includes a vehicle door provided in the embodiment of the third aspect of the present application.

[0083] According to the vehicle provided in the embodiment of the present application, the use of the aforementioned vehicle door improves the user experience.

[0084] The handle device 200 provided in the embodiment of the present application will be described in detail with reference to Figures 1 to 9 in a specific embodiment. It will be understood that the following description is merely an exemplary explanation and is not a specific limitation of the present application.

[0085] In this embodiment, as shown in FIGS. 1 to 9 , a handle device 200 includes a handle 2 and a transmission assembly 100. The transmission assembly 100 includes a base 1, a link assembly 43, a rotating member 42, a crankshaft 3, and a rotating arm 6. The crankshaft 3 is provided with an abutment member 5, a first alignment member 31, and a first reset member 7. The abutment member 5 and the first alignment member 31 are fixed to the crankshaft 3. Two ends of the first reset member 7 are fixed to the base 1 and the first alignment member 31. The link assembly 43 includes a first link 431 and a second link 432. One end of the first link 431 is connected to one end of the handle 2 and rotatably cooperates with the one end of the handle 2. The other end of the first link 431 is connected to one end of the second link 432 and rotatably cooperates with one end of the second link 432. The other end of the second link 432 is fixed to the rotating member 42 and rotates together with the rotating member 42. The rotating member 42 is provided with a second alignment member 41 and a second reset member 8. Two ends of the second reset member 8 are fixed to the base 1 and a slot structure 432a of the second link 432. One end of the crankshaft 3 facing the first alignment member 31 is fixed and connected to the rotating arm 6. One end of the rotating arm 6 remote from the crankshaft 3 is connected to the door lock push rod 9 and rotatably cooperates with the door lock push rod 9.

[0086] The handle device 200 has an initial locked state, a pushed-out state, and an unlocked state. For example, in the example of FIG. 9 , the handle 2 is in the initial locked state, as shown in position A in FIG. 9 . The handle 2 is in the pushed-out state, as shown in position B in FIG. 9 . The handle 2 is in the unlocked state, as shown in position C in FIG. 9 . Naturally, when the handle 2 is in the initial locked state and the pushed-out state, the door lock push rod 9 does not move, as shown in position D in FIG. 9 . When the handle 2 is in the unlocked state, the door lock push rod 9 pushes the lock cylinder 101 to unlock, as shown in position E in FIG. 9 .

[0087] In the initial lock state, the first alignment member 31 and the second alignment member 41 are spaced apart, and the gap between them is a preset gap. When the handle 2 is switched from the initial lock state to the push state, the handle 2 moves the first link 431 in a direction away from the base 1. The first link 431 rotates the second link 432 toward the handle 2. The second link 432 rotates the rotating member 42 relative to the base 1, causing the second alignment member 41 to rotate toward the first alignment member 31. After the second alignment member 41 completes its idle stroke (the gap between the first alignment member 31 and the second alignment member 41), the second alignment member 41 is in contact with the first alignment member 31 in preparation for the unlocking process.

[0088] When the handle 2 is switched from the pushed-out state to the unlocked state, the user pulls the handle 2, continuing to move the first link 431 in a direction away from the base 1. The first link 431 rotates the second link 432 toward the handle 2. The second link 432 continues to rotate the rotating member 42 relative to the base 1, rotating the second alignment member 41 toward the first alignment member 31. The second alignment member 41 rotates the first alignment member 31 around the crankshaft 3. The crankshaft 3 rotates together with the first alignment member 31, rotating the rotating arm 6 in a direction away from the base 1. The rotating arm 6 rotates to move the door lock push rod 9 in a direction away from the base 1. The door lock push rod 9 moves to retract the lock cylinder 101, thereby performing unlocking.

[0089] When the user releases the handle 2, the reset torque of the first reset member 7 rotates the crankshaft 3. The crankshaft 3 rotates to rotate the first alignment member 31 and the abutment member 5 toward the base 1 until the abutment member 5 abuts against the base 1. In this case, the first alignment member 31 is returned to its initial position, and at the same time, the reset torque of the second reset member 8 rotates the rotating member 42 in a direction away from the first link 431. The rotating member 42 rotates to rotate the second alignment member 41 and the second link 432 in a direction away from the first alignment member 31. The second link 432 rotates to move the first link 431 toward the rotating member 42. The first link 431 moves to move the handle 2 toward the base 1 until the handle 2 is switched from the unlocked state to the pushed state. In this case, the second alignment member 41 moves to the position of the second alignment member 41 when the handle 2 is in the pushed-out state.

[0090] When the handle 2 is switched from the pushed-out state to the initial locked state, the handle 2 gradually retracts into the accommodating cavity 1a of the base 1. The first link 431 moves toward the rotating member 42 to rotate the second link 432. The second link 432 rotates to rotate the rotating member 42 in a direction away from the first link 431 to reset it. The rotating member 42 rotates to return the second alignment member 41 to its initial position. In this case, the first alignment member 31 and the second alignment member 41 are spaced apart by a preset distance so that the handle device 200 completes a cycle from unlocking to resetting the mechanism.

[0091] 10 to 13, one embodiment of the present application provides a handle device 200. The handle device 200 may be applied to a vehicle. The handle device 200 includes a handle 2, a transmission assembly 100, and a door lock push rod 9.

[0092] The transmission assembly 100 includes a rotating member 42 and a transmission shaft 110. An input end of the rotating member 42 is connected to the handle 2. For example, when the handle 2 is pulled, the rotating member 42 can be rotated through the transmission assembly. A handle device 200 including the handle 2 is capable of rotating the rotating member 42. An output end of the rotating member 42 is connected to an input end of the transmission shaft 110. The rotating member 42 is capable of rotating the transmission shaft 110.

[0093] 10 and 11, the input end of the door lock push rod 9 is connected to the output end of the transmission shaft 110. The transmission shaft 110 is capable of moving the door lock push rod 9 to unlock the lock 201.

[0094] 12 and 13 , when the handle 2 is pulled in the Y direction, the rotating member 42 can be rotated through the transmission assembly. When the rotating member 42 rotates, the transmission shaft 110 can be rotated. When the transmission shaft 110 rotates, it can push the door lock push rod 9 to move. The lock 201 may be provided with a guide groove that cooperates with the door lock push rod 9, thereby promoting a stable connection between the door lock push rod 9 and the lock 201 when the push rod is moving. The lock 201 is unlocked through the door lock push rod 9. The handle device 200 provided in the embodiment of the present application uses the transmission assembly 100 to implement the connection and transmission between the handle 2 and the door lock push rod 9, thereby avoiding the large space occupied by a pull wire mechanism between a conventional door lock and a handle, simplifying the structure of the handle device 200, and improving the assembly efficiency of the handle device 200.

[0095] Furthermore, the transmission between the handle 2 and the door lock push rod 9 is carried out through the transmission assembly 100, thereby avoiding friction between the components inside the handle device 200 and reducing the noise of the handle device 200 during unlocking and locking.

[0096] The handle device 200 provided in the embodiment of the present application includes a handle 2, a transmission assembly 100, and a door lock push rod 9. The transmission assembly 100 includes a rotating member 42 and a transmission shaft 110. The input end of the rotating member 42 is connected to the handle 2. For example, when the handle 2 is pulled, the rotating member 42 can be rotated through the transmission assembly. The handle device 200 including the handle 2 is capable of rotating the rotating member 42. The output end of the rotating member 42 is connected to the input end of the transmission shaft 110. The rotating member 42 is capable of rotating the transmission shaft 110. The input end of the door lock push rod 9 is connected to the output end of the transmission shaft 110. The transmission shaft 110 is capable of moving the door lock push rod 9 to unlock the lock 201. The handle device 200 uses a transmission assembly 100 to implement the transmission between the handle 2 and the door lock push rod 9, which simplifies the structure of the handle device 200 and improves the assembly efficiency and unlocking reliability of the handle device 200.

[0097] Optionally, the transmission assembly further includes a steering mechanism. The steering mechanism includes at least a first alignment member 31 and a second alignment member 41. The first alignment member 31 is disposed on the transmission shaft 110. The second alignment member 41 is disposed on the rotation member 42. A transmission angle is formed between the rotation axis of the second alignment member 41 and the rotation axis of the first alignment member 31.

[0098] Specifically, in order to fully utilize the assembly space of the handle device 200, since there are many parts that cooperate with each other in the position for disposing the handle device 200 on the vehicle, the disposing directions of the rotating member 42 and the transmission shaft 110 may be different, that is, an included angle is formed between the rotating member 42 and the transmission shaft 110. For ease of transmission between the rotating member 42 and the transmission shaft 110 in different directions, the rotating member 42 and the transmission shaft 110 may be connected through a steering mechanism. For example, the second alignment member 41 is connected to the rotating member 42. The first alignment member 31 is connected to the transmission shaft 110. The rotation axis of the rotating member 42 is also the rotation axis of the second alignment member 41. The rotation axis of the transmission shaft 110 is also the rotation axis of the first alignment member 31. Therefore, when a transmission angle is formed between the rotating member 42 and the transmission shaft 110, i.e., when a transmission angle is formed between the rotation axis of the first alignment member 41 and the rotation axis of the second alignment member 31, stable transmission between the rotating member 42 and the transmission shaft 110 can still be ensured.

[0099] Optionally, referring to Figures 10 and 11, the second alignment member 41 is one of the cam 311 and the protrusion 413. The first alignment member 31 is the other of the cam and the protrusion. The second alignment member 41 is fixed to the output end of the rotating member 42. The first alignment member 31 is fixed to the input end of the transmission shaft 110.

[0100] During rotation of the rotating member, the second alignment member 41 can contact the first alignment member 31 to cause the first alignment member 31 to rotate.

[0101] Specifically, in one embodiment, the second alignment member 41 is a protrusion 413. The first alignment member 31 is a cam 311. When the handle 2 is pulled, the rotating member 42 and the protrusion 413 on the rotating member 42 can be rotated. The protrusion 413 cooperates with the cam 311, so that the protrusion 413 can rotate the cam 311 when rotating. When the cam 311 and the transmission shaft 110 rotate synchronously, the door lock push rod 9 can be moved through the transmission connection between the transmission shaft 110 and the door lock push rod 9, and unlocking of the lock 201 can be performed through the rotation of the transmission shaft 110, thus improving the unlocking efficiency of the handle device 200.

[0102] In another embodiment, the second alignment member 41 is a cam 311 and the first alignment member 31 is a protrusion 413. Similarly, the transmission shaft 110 can move the door lock push rod 9 through cooperation between the protrusion 413 and the cam 311.

[0103] Optionally, the second matching member 41 is a first bevel gear. The first matching member 31 is a second bevel gear. The first bevel gear is fixed to the input end of the transmission shaft 110. The second bevel gear is fixed to the output end of the rotating member 42. The second bevel gear is engaged with the first bevel gear.

[0104] When the rotating member 42 rotates, it causes the second bevel gear to rotate, which in turn causes the first bevel gear and the transmission shaft 110 to rotate synchronously.

[0105] Specifically, when the handle 2 is pulled, the rotating member 42 and the second bevel gear on the rotating member 42 can be rotated. The second bevel gear cooperates with the first bevel gear, so that the second bevel gear can rotate the first bevel gear when rotating. When the first bevel gear and the transmission shaft 110 rotate synchronously, the door lock push rod 9 can be moved through the transmission connection between the transmission shaft 110 and the door lock push rod 9, and unlocking of the lock 201 can be performed through the rotation of the transmission shaft 110, thereby improving the unlocking efficiency of the handle device 200.

[0106] Optionally, the included angle for transmission is greater than 0 degrees and less than 180 degrees.

[0107] Specifically, in order to fully utilize the assembly space of the handle device 200 when the rotating member 42 and the transmission shaft 110 are assembled, the rotating member 42 and the transmission shaft 110 can be connected through a steering mechanism to form a transmission angle between the rotating member 42 and the transmission shaft 110 based on ensuring the transmission stability of the rotating member 42 and the transmission shaft 110.

[0108] The transmission angle may be specifically an acute angle, a right angle, or an obtuse angle. In one embodiment, referring to Figure 10, the rotating member 42 and the transmission shaft 110 are perpendicular to each other so that the transmission angle is a right angle.

[0109] Optionally, referring to Figures 10 and 11, the transmission shaft 110 further includes a crankshaft 3 and a rotating arm 6. One end of the crankshaft 3 is connected to the steering mechanism. The other end of the crankshaft 3 is connected to a first end of the rotating arm 6. A second end of the rotating arm 6 is rotatably connected to an input end of a door lock push rod 9.

[0110] Specifically, when the cam 311 of the steering mechanism is connected to the rotating arm 6 through the crankshaft 3, the rotation of the cam 311 can be transmitted to the rotating arm 6 through the crankshaft 3, which is convenient for transmission between the transmission shaft 110 and the door lock push rod 9. The input end of the door lock push rod 9 is connected to the rotating arm 6, so that when the rotating arm 6 rotates, the door lock push rod 9 can be pushed to move during the rotation of the rotating arm 6, to unlock the lock 201 through the door lock push rod 9.

[0111] Optionally, referring to Fig. 10, the handle device 200 further includes a base 1. The base 1 is provided with a mounting wall 131. The crankshaft 3 is rotatably connected to the mounting wall 131.

[0112] Specifically, when the crankshaft 3 transmits the rotation of the cam 311 to the rotating arm 6, the crankshaft 3 needs to be able to rotate stably. The base 1 can function as a base for the handle 2. The mounting wall 131 is provided with a through-hole. The crankshaft 3 can pass through the through-hole and rotate relative to the mounting wall 131 to increase the rotational flexibility of the crankshaft 3 while ensuring the placement stability of the crankshaft 3.

[0113] Optionally, referring to Figures 10 and 11, the handle device 200 further includes a first reset member 7. The first reset member 7 is connected to the crankshaft 3 and configured to reset the crankshaft 3 after unlocking is performed by the door lock push rod 9.

[0114] Specifically, since the handle device 200 needs to be unlocked and locked frequently, after the unlocking of the lock 201 is performed through the door lock push rod 9 when the transmission shaft 110 rotates, in order to facilitate the next unlocking of the handle device 200, the first reset member 7 can reset the crankshaft 3 to the lock position before unlocking, which can not only lock the handle device 200, but also facilitate the next unlocking of the handle device 200.

[0115] For example, when the handle device 200 is applied to unlocking and locking a vehicle door, the handle device 200 can be convenient for a user to open the vehicle door after it has been unlocked. When a user gets into the vehicle and closes the vehicle door, the first reset member 7 can reset the crankshaft 3 to the lock position before unlocking in order to lock the vehicle door.

[0116] Optionally, the first reset member is a torsion spring, one end of which is fixed and connected to the base, and the other end of which is connected to and disposed on the side of the first alignment member 31 away from the second alignment member 41.

[0117] Specifically, the torsion spring may be sleeved onto the crankshaft 3. As the crankshaft 3 rotates together with the first alignment member 31, the position of the base is relatively fixed, so that the first alignment member 31 can rotate and elastically deform the torsion spring. If the lock 201 needs to be locked after being unlocked, the elastic restoring force of the torsion spring can rotate the first alignment member 31 and the crankshaft 3 together in the opposite direction so that the transmission shaft 110 is reset to the locked position before being unlocked.

[0118] 12 and 13, in one embodiment, the first reset member 7 includes a first torsion spring and a second torsion spring. The base 1 is provided with two parallel mounting walls 131. The first torsion spring and the second torsion spring are both sleeved onto the crankshaft 3. One end of the first torsion spring is connected to one of the mounting walls 131. The other end of the first torsion spring is connected to the first alignment member 31. One end of the second torsion spring is connected to the other of the mounting walls 131. The other end of the second torsion spring is connected to the rotating arm 6.

[0119] The crankshaft 3 can pass through two parallel mounting walls 131 in sequence. When the crankshaft 3 rotates together with the first alignment member 31 and the rotating arm 6, the positions of the mounting walls 131 are relatively fixed, so that the first alignment member 31 and the rotating arm 6 can rotate and elastically deform the first torsion spring and the second torsion spring. If the lock 201 needs to be locked after being unlocked, the elastic restoring forces of the first torsion spring and the second torsion spring can rotate the first alignment member 31, the crankshaft 3, and the rotating arm 6 together in opposite directions so that the transmission shaft 110 is reset to the locked position before being unlocked.

[0120] Furthermore, the first reset member 7 may alternatively be a unidirectional motor. The resetting of the crankshaft 3 may be performed via a unidirectional motor.

[0121] Optionally, the handle device 200 further includes a push-out assembly. The handle device 200 is configured to connect to a door mounting support 203. The push-out assembly is connected to the handle 2.

[0122] When the lock 201 is in an unlocked state, the pusher assembly is able to push the handle 2 out of the door mounting support 203 .

[0123] When the lock 201 is in the locked state, the handle 2 is flush with the door mounting support 203 .

[0124] Specifically, when the handle 2 is pulled while the lock 201 is in the unlocked state, the rotating member 42 can be rotated through the transmission assembly. When the rotating member 42 rotates, it can rotate the transmission shaft 110. When the transmission shaft 110 rotates, it can push and move the door lock push rod 9 to unlock the lock 201 through the door lock push rod 9. To make it easier to pull the handle 2, the handle 2 can be pushed out of the door mounting support 203 through the push-out assembly, allowing a user to apply a pulling force to the handle 2.

[0125] When the lock 201 is in the locked state, the first reset member 7 can reset the transmission shaft 110 to the locked position before unlocking. When the transmission shaft 110 is resetting, it can retract the handle 2 through the rotating member 42. For example, to implement the design of the hidden handle device 200, the handle 2 retracts to be flush with the outside of the door mounting support 203, so that the handle device 200 is integrated with the overall styling of the vehicle and improves the appearance of the vehicle.

[0126] In one embodiment, the unlocked state of lock 201 includes a first unlocked stage and a second unlocked stage.

[0127] 12, when the lock 201 is in a first unlocking stage, an out-pull gap 202 is formed between the handle 2 and the door mounting support 203. Specifically, the handle 2 may be pushed out of the door mounting support 203 through an extrusion assembly to form the out-pull gap 202 between the handle 2 and the door mounting support 203.

[0128] 13 , when the lock 201 is in the second unlocking stage, if a user pulls the handle 2 outward through the drawer gap 202, the handle 2 can rotate the rotating member 42, causing the rotating member 42 to rotate the transmission shaft 110. When the transmission shaft 110 rotates, it can push and move the door lock push rod 9 to unlock the lock 201 through the door lock push rod 9. When the transmission shaft 110 rotates, the first reset member 7 can be deformed to be in an elastically deformed state.

[0129] Optionally, when the lock 201 is in the locked state, the first reset member 7 rotates the transmission shaft 110 in the opposite direction to reset the transmission shaft 110 .

[0130] Specifically, the first reset member 7 in an elastically deformed state can rotate the transmission shaft 110 in the opposite direction through the elastic restoring force of the first reset member to reset the transmission shaft 110. Furthermore, when the transmission shaft 110 rotates in the opposite direction, it can rotate the rotating member 42 in the opposite direction, and then the rotating member 42 retracts and resets the handle 2 so that the handle 2 is flush with the door mounting support 203.

[0131] An embodiment of the present application further provides a vehicle. The vehicle includes a handle device 200 and a lock 201. The lock 201 is provided with a guide groove. An output end of a door lock push rod is disposed in the guide groove.

[0132] Specifically, one handle device 200 may be provided for each door of a vehicle. The handle 2 of the handle device 200 is connected to the rotating member 42 and can move the rotating member 42. The transmission shaft 110 is connected to the rotating member 42. When the rotating member 42 moves, the transmission shaft 110 can be rotated. If the output end of the door lock push rod 9 is disposed in a guide groove, the door lock push rod 9 can be conveniently stably connected to the lock 201 when moving. The handle device 200 uses the transmission assembly 100 to transmit power between the handle 2 and the door lock push rod 9, which simplifies the structure of the handle device 200, improves the assembly efficiency of the handle device 200, and ensures the efficiency and safety of locking and unlocking doors on a vehicle.

[0133] Optionally, referring to Figure 10, the vehicle includes a door mounting support 203. The handle device 200 is disposed on the door mounting support 203.

[0134] Specifically, when the vehicle door is closed, the first reset member 7 can reset the transmission shaft 110 to the lock position before unlocking. When the transmission shaft 110 is resetting, it can retract the handle 2 through the rotating member 42. For example, to implement the design of the hidden handle device 200, the handle 2 retracts so as to be flush with the outer sheet metal surface of the door mounting support 203, so that the handle device 200 is integrated with the overall styling of the vehicle and improves the appearance of the vehicle.
