Embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, where same or similar reference numerals throughout represent same or similar elements or elements having same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are merely used to explain this application, and shall not be construed as a limitation on this application.
The following disclosure provides many different embodiments or examples to implement different structures of this application. To simplify the disclosure of this application, components and configurations for specific examples are described below. Certainly, they are merely examples and are not intended to limit this application. In addition, this application may repeat reference numerals and/or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, this application provides examples of various specific processes and materials, but person of ordinary skill in the art may be aware of the application of other processes and/or the use of other materials.
Below, with reference to the accompanying drawings, a transmission assembly 100 for a handle apparatus 200 according to an embodiment of this application is described. The transmission assembly 100 and a handle 2 are arranged in the handle apparatus 200. The handle apparatus 200 is mounted on a vehicle door body of a vehicle. The vehicle door body is provided with a lock cylinder 101. A vehicle body is provided with a locking part that cooperates with the lock cylinder 101. After extending, the lock cylinder 101 can cooperate with the locking part to lock the vehicle door body. For example, when the lock cylinder 101 retracts, the lock cylinder is disengaged from the locking part, so that the vehicle door body can be opened. The door lock push rod 9 is movable to at least drive the lock cylinder 101 to retract. When the door lock push rod 9 moves to drive the lock cylinder 101 to retract, 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 driven to retract or extend through reciprocating movement of the door lock push rod 9, or the lock cylinder 101 may be driven to retract only through movement of the door lock push rod 9. When the door lock push rod 9 moves in a direction away from the lock cylinder 101, the lock cylinder 101 may be driven to extend through a reset spring.
As shown in FIG. 4 to FIG. 8, the transmission assembly 100 includes a base 1, a crankshaft 3, a first matching member 31, a second matching member 41, and an abutting member 5. The crankshaft 3 is rotatably arranged on the base 1. An output end of the crankshaft 3 is adapted to connect a door lock push rod 9 and drives the door lock push rod 9 to move. The first matching member 31 is arranged on an input end of the crankshaft 3. The first matching member 31 rotates along an axial direction of the crankshaft 3 as the crankshaft 3 rotates. The second matching member 41 is configured to rotate under the action of an external force. The second matching member 41 is adapted to cooperate with the first matching member 31 to drive the first matching member 31 to rotate. The first matching member 31 drives the door lock push rod 9 to move through the crankshaft 3 to implement unlocking. The abutting member 5 is arranged on the crankshaft 3 and rotates synchronously with the crankshaft 3. When the transmission assembly 100 is in an initial locked state, the abutting member 5 abuts against the base 1, and the abutting member 5 limits rotation of the crankshaft 3, thereby ensuring that when the transmission assembly 100 is restored to the initial locked state, the first matching member 31 is restored to an initial position, that is, a position of the first matching member 31 is restored to a position when the transmission assembly 100 is in the initial locked state, so that the first matching member 31 is more accurately restored to the initial position under the action of a reset force to ensure accuracy of next unlocking. For example, the second matching member 41 is prevented from contacting the first matching member 31 and pushing the first matching member 31 to rotate to implement unlocking by accident during a process of switching from the initial locked state to an unlocked state, or failure to unlock caused by an insufficient moving distance of the first matching member 31 when pushed by the second matching member 41 is avoided, thereby ensuring reliability and accuracy of unlocking implemented by the transmission assembly 100.
Specifically, when the transmission assembly 100 is switched from the initial locked state to the unlocked state, the second matching member 41 rotates toward the first matching member 31 under the action of an external force, and the second matching member 41 contacts the first matching member 31 to drive the first matching member 31 to rotate, so that the second matching member 41 drives the first matching member 31 to rotate around the crankshaft 3, the crankshaft 3 rotates with the first matching member 31 to drive the door lock push rod 9 to move, and the door lock push rod 9 pushes the lock cylinder 101 to retract to unlock the lock cylinder 101.
According to the handle apparatus 200 provided in the embodiment of this application, the abutting member 5 abuts against the base 1 to limit a rotation stroke of the crankshaft 3, so that after unlocking, the first matching member 31 can be restored to the initial position to prepare for next unlocking, thereby preventing the handle apparatus 200 from being unlocked in advance or failing to be unlocked, and improving reliability and accuracy of unlocking implemented by the transmission assembly 100.
In some embodiments, as shown in FIG. 7, the transmission assembly 100 further includes a buffer member 11. The buffer member 11 is arranged on the base 1. When the handle 2 is in the initial locked state, the abutting member 5 abuts against the buffer member 11 to reduce collision impact between the abutting member 5 and the base 1, which is beneficial in reducing noise generated when the abutting member 5 contacts the base 1, thereby reducing noise generated when the vehicle door body is unlocked, and improving the user experience.
When the handle 2 is in the initial locked state, the abutting member 5 abuts against the buffer member 11 to limit movement of the abutting member 5, thereby limiting rotation of the crankshaft 3 and providing a circumferential limitation for the crankshaft 3.
Furthermore, the base 1 is provided with a mounting groove. The buffer member 11 is mounted in the mounting groove. For example, the mounting groove may extend through a wall thickness of the base 1, and the buffer member 11 is inserted into the mounting groove, so that the buffer member 11 may be positioned and mounted, preventing the buffer member 11 from being misplaced and unable to abut against the abutting member 5.
In some embodiments, as shown in FIG. 5 and FIG. 8, the abutting member 5 includes an abutting protrusion rib 51. The abutting member 5 abuts against the base 1 through the abutting protrusion rib 51 to reduce a contact area between the abutting member 5 and the base 1, thereby further reducing noise generated when the abutting member 5 contacts the base 1.
In some embodiments, as shown in FIG. 5 and FIG. 8, the abutting 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 limitation for the crankshaft 3 through cooperation between the first limiting member 52 and the base 1.
For example, in the example of FIG. 8, a limiting groove 1b is formed in the base 1. The 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 protrusion 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.
The abutting member 5 abuts against the buffer member 11 arranged on the base 1, and meanwhile cooperates with the base 1 through the first limiting member 52 to provide circumferential and axial limitations for the crankshaft 3, to reduce influence on a preset gap between the first matching member 31 and the second matching member 41 caused by movement of the crankshaft 3, and to ensure that spacing between the first matching member 31 and the second matching member 41 is unchanged in the initial locked state, reducing the possibility of unlocking in advance or failure in unlocking of the lock cylinder 101 caused by a change in the spacing between the first matching member 31 and the second matching member 41, and improving reliability of the handle apparatus 200.
In some embodiments, as shown in FIG. 5, the transmission assembly 100 further includes a rotating arm 6. The rotating arm 6 is fastened and connected to one end of the crankshaft 3. The rotating arm 6 is adapted to rotatably cooperate with an input end of the door lock push rod 9. An output end of the door lock push rod 9 cooperates with the lock cylinder 101. The rotating arm 6 rotates to drive the door lock push rod 9 to move. The door lock push rod 9 moves to drive the lock cylinder 101 to retract to unlock the lock cylinder 101.
In some embodiments, as shown in FIG. 5, the crankshaft 3 and at least one of the rotating arm 6, the first matching member 31 and the abutting member 5 are an integral member (for example, may be an integrally molded member), so that structural strength and stability of the crankshaft 3, the rotating arm 6, the first matching member 31, and the abutting member 5 are improved, thereby improving a service life of the handle apparatus 200. Meanwhile, the crankshaft 3, the rotating arm 6, the first matching member 31, and the abutting member 5 are the integral member, so that a number of components of the handle apparatus 200 is reduced, and a structure of the handle apparatus 200 is simplified, thereby improving use reliability of the handle apparatus 200, and enabling assembly of the handle apparatus 200 to be simpler.
Optionally, the crankshaft 3, the rotating arm 6, the first matching member 31, and the abutting member 5 are separate members.
In related technologies, a handle apparatus drives a transmission assembly through a handle, and the transmission assembly drives a crankshaft to rotate and then pulls a pull wire (such as a Bowden cable) to unlock a vehicle door. However, the pull wire is a flexible power transmission element, and the pull wire generally includes two parts: a multi-strand steel wire inside and a plastic sleeve wrapped around the outside of the steel wire. However, during an unlocking process, the steel wire is moving, and the plastic sleeve is a fastened member, so that there is a movement fit clearance between the two. When the vehicle is in a humid environment (such as rain or car washing), the movement clearance of the pull wire may be wet or affected by water infiltration. When the vehicle is in a low temperature environment, the steel wire and the plastic sleeve may freeze, so that an unlocking function cannot be implemented.
In the handle apparatus 200 of this application, the handle 2 cooperates with the rotating member 42, the rotating member 42 drives the first matching member 31 to rotate through the second matching 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, so that reliable and stable transmission is ensured through transmission of mechanical components, avoiding influence on the unlocking function of the handle apparatus 200 due to the vehicle being in the humid, cold or other environments, and thereby ensuring reliability of the handle apparatus 200.
In some embodiments, as shown in FIG. 5, the handle apparatus 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 may 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, that is, to reset a position state of the crankshaft 3 to a position state of the crankshaft 3 in the initial locked state.
It may be understood that the first reset member 7 cooperates with the crankshaft 3 to apply the reset force to the crankshaft 3, and the reset force makes the crankshaft 3 have a trend to rotate so that the abutting member 5 abuts against the base 1, and therefore, when the handle 2 is switched from the unlocked state to an ejected state. The crankshaft 3 rotates under the action of the reset force of the first reset member 7, driving the first matching member 31 to restore to an initial position, and meanwhile, the abutting member 5 abuts against the base 1 to limit rotation of the crankshaft 3, ensuring that the first matching member 31 is accurately restored to the initial position, and preparing for next unlocking of the vehicle door body, where the first matching member 31 is in the initial position, that is, a position where the second matching member 31 does not apply a rotation force to the first matching member 41, and in this case, the abutting member 5 abuts against the base 1.
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 is provided with a reset spring, after unlocking is completed, the reset spring drives the lock cylinder 101 to extend to drive the door lock push rod 9 to move toward the base 1, driving the crankshaft 3 to reset to the initial locked state. Alternatively, the transmission assembly 100 is further provided with a reset mechanism, and the reset mechanism resets the crankshaft 3 to the initial locked state after unlocking is completed.
In some embodiments, as shown in FIG. 5, the first reset member 7 is a torsion spring and is sleeved on the crankshaft 3. Two ends of the first reset member 7 are respectively fastened to the base 1 and the first matching member 31, so that the first reset member 7 provides a reset torque for rotation of the crankshaft 3 and driving the first matching member 31 to restore to the initial position, ensuring that the first matching member 31 is restored to the initial position when the handle 2 is switched from the unlocked state to the ejected state. Furthermore, the torsion spring directly acts on the first matching member 31, thereby ensuring reliable transmission of the force.
For example, in the examples of FIG. 5 and FIG. 8, two ends of the first reset member 7 are respectively fastened to the base 1 and the first matching member 31. When the handle is switched from the unlocked state to the ejected state, the second matching member 41 rotates toward a position away from the first matching member 31. The first reset member 7 has a reset torque to drive the crankshaft 3 to rotate. The crankshaft 3 drives the abutting member 5 to rotate until the abutting member 5 abuts against the base 1. The abutting member 5 limits rotation of the crankshaft 3. Therefore, after the handle 2 completes the process of switching from the unlocked state to the ejected state, the first matching member 31 may also be restored to the initial position, to prepare for next unlocking.
In some embodiments, as shown in FIG. 6 and FIG. 7, the handle apparatus 200 includes a handle 2 arranged on the 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. The second matching member 41 is arranged on the rotating member 42. The link assembly 43 cooperates with the handle 2 and the rotating member 42 separately, to transmit a movement trend of the handle 2 (for example, a movement trend of switching from the initial locked state to the unlocked state) to the rotating member 42 through the link assembly 43, driving the rotating member 42 to rotate, so that the second matching member 41 rotates with the rotating member 42, and therefore, the second matching member 41 pushes the first matching member 31 to rotate, thereby implementing unlocking.
In some embodiments, as shown in FIG. 4, the second matching member 41 includes a first part 411 and a second part 412, with an included angle therebetween. The first part 411 is connected to the rotating member 42. During an unlocking process, the first part 411 and the second part 412 can both contact the first matching member 31, to increase a contact area between the first matching member 31 and the second matching member 41. Meanwhile, the included angle between the first part 411 and the second part 412 is toward the first matching member 31, so that reliability and stability of the second matching member 41 driving the first matching member 31 to rotate are improved, ensuring reliability of the unlocking process.
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 with the base 1 and the link assembly 43 separately. The second reset member 8 drives the link assembly 43 to drive the handle 2 to rotate toward the ejected state. The link assembly 43 is driven to move through a reset torque of the second reset member 8, driving the handle 2 to restore from the unlocked state to the ejected state, thereby implementing automatic resetting of the handle 2 after the vehicle door body is unlocked. Certainly, it may be understood that a position for arrangement of the second reset member 8 is not limited thereto. For example, the second reset member 8 may alternatively directly act on the handle 2 to drive the handle 2 to rotate from the unlocked state to the ejected state.
In some embodiments, as shown in FIG. 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, the other end of the first link 431 rotatably cooperates with one end of the second link 432, and the other end of the second link 432 is sleeved on the rotating member 42, to transmit a movement trend of the handle 2 (for example, switching from the initial locked state to the unlocked state, etc.) to the rotating member 42, so that the rotating member 42 rotates to drive the second matching member to rotate, and therefore, the second matching member 41 relatively cooperates with the first matching member 31 to complete unlocking.
For example, in the examples of FIG. 3 and FIG. 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 on 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 drives the first link 431 to move. The first link 431 drives one end of the second link 432 to rotate toward the handle 2. The second link 432 drives the rotating member 42 to rotate relative to the base 1, driving the second matching member 41 to approach the first matching member 31. When the second matching member 41 completes an idle stroke and is in contact with the first matching member 31, the handle 2 continues to move in a direction away from the base 1. The second matching member 41 drives the first matching member 31 to rotate around the crankshaft 3. The crankshaft 3 rotates with the first matching member 31 to drive the door lock push rod 9 to move. The door lock push rod 9 pushes the lock cylinder 101 to retract to unlock the lock cylinder 101.
In some embodiments, as shown in FIG. 7, the second reset member 8 is a torsion spring. Two ends of the second reset member 8 are respectively fastened to the base 1 and the second link 432, so that the second reset member 8 provides a reset torque for rotation of the rotating member 42 and the link assembly 43 to drive the handle 2 to restore to an ejected state, and therefore, the handle 2 is automatically switched from the unlocked state to the ejected state, to prepare for the handle 2 switching from the ejected state to the initial locked state.
For example, in the examples of FIG. 6 and FIG. 7, the second link 432 is provided with a slot structure 432a. Two ends of the second reset member 8 are respectively fastened to the base 1 and the slot structure 432a. During a process of switching from the unlocked state to the initial locked state, the second reset member 8 has a reset torque to drive the rotating member 42 and the second link 432 to rotate. The second link 432 rotates to drive the first link 431 to move toward the rotating member 42. The first link 431 drives the handle 2 to rotate toward the base until the handle 2 is restored 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 matching member 41 rotates with the rotating member 42, so that after unlocking is completed, the second matching member 41 is automatically restored from a position of the second matching member 41 when the handle 2 is in the unlocked state to a position of the second matching member 41 when the handle 2 is in the initial locked state.
It should be noted that, when the handle 2 is switched from the unlocked state to the initial locked state, and the first matching member 31 and the second matching member 41 are restored from the positions in the unlocked state to the positions in the initial locked state, there is no interference between the first matching member 31 and the second matching member 41, and relative movement between the first matching member 31 and the second matching member 41 are not affected.
It should be noted that a structure of the link assembly 43 is not limited thereto. For example, the link assembly 43 may be a three-link assembly, or the link assembly 43 may include an eccentric wheel structure, provided that a torque of the handle may be transmitted to the crankshaft 3.
A handle apparatus according to an embodiment of a second aspect of this application includes: a handle 2 and a transmission assembly 100. The handle 2 is movably mounted on the base 1. The handle 2 moves, so that the handle apparatus 200 is switched between an initial locked state and an unlocked state. The transmission assembly 100 is the transmission assembly 100 provided in the foregoing embodiment of the first aspect of this application, and the handle 2 cooperates with the second matching member 41 to drive second matching member 41 to rotate.
According to the handle apparatus 200 provided in the embodiment of this application, accuracy and reliability of unlocking implemented by the handle apparatus 200 are improved by using the foregoing transmission assembly 100.
In some embodiments, as shown in FIG. 1 to FIG. 3 and FIG. 7 to FIG. 9, the base 1 is provided with an accommodating cavity 1a. The handle apparatus 200 further has an ejected state. In the initial locked state, the handle 2 is accommodated in the accommodating cavity 1a. The handle 2 is accommodated in the accommodating cavity 1a, so that the handle 2 is hidden in the accommodating cavity 1a. An upper side surface of the handle 2 may be flush with a surface of a vehicle door body or lower than the surface of the vehicle door body, or may be slightly higher than the surface of the vehicle door body, which is beneficial in reducing airflow resistance when the vehicle is traveling and improving appearance of the vehicle. In the ejected state and the unlocked state, at least a part of the handle 2 is located outside the accommodating cavity 1a to facilitate user operation.
It may be understood that, in the ejected state, the handle 3 may be parallel to the vehicle door body, or may be arranged at a certain angle to the vehicle door body, which is not specifically limited here, provided that at least a part of the handle 3 is located outside the accommodating cavity.
The handle 2 is movably arranged on the base 1 to switch between the initial locked state and the ejected state. For example, an automated device such as a drive motor may be arranged in the vehicle door body to automatically switch the handle 2 from the initial locked state to the ejected state or switch the handle 2 from the ejected state to the initial locked state, to facilitate the use of users. The handle 2 is rotatable relative to the base 1 to switch between the ejected state and the unlocked state. For example, when the handle 2 is in the ejected state, the user manually pulls the handle 2 to unlock the vehicle door.
In the initial locked state, a gap is provided between the first matching member 31 and the second matching member 41. After rotating by the preset gap from the initial locked state, the second matching member 41 drives the first matching member 31 to rotate. The first matching member 31 drives the door lock push rod 9 to move through the crankshaft 3 to implement unlocking.
Specifically, when the handle 1 is driven to switch from the initial locked state to the ejected state, the handle 2 cooperates with the connecting link assembly 43 to drive the rotating member 42 to rotate. The rotating member 42 rotates to drive the second matching member 41 to rotate toward the first matching member 31. When the second matching member 41 completes an idle stroke (the gap between the first matching member 31 and the second matching member 41), the second matching member 41 contacts the first matching member 31, to prepare for an unlocking process. When the handle 2 is driven to switch from the ejected state to the unlocked state, the handle 2 continues to cooperate with the link assembly 43 to drive the rotating member 42 to rotate. The rotating member 42 rotates to drive the second matching member 41 to rotate toward the first matching member 31. In this case, the second matching member 41 is in contact with the first matching member 31. The second matching member 41 drives the first matching member 31 to rotate around the crankshaft 3. The crankshaft 3 rotates with the first matching member 31 to drive the door lock push rod 9 to move. The door lock push rod 9 pushes the lock cylinder 101 to retract to unlock the lock cylinder 101.
A vehicle door according to an embodiment of a third aspect of this application includes a vehicle door body, a handle apparatus 200, a lock cylinder 101, and a door lock push rod 9. The handle apparatus 200 is the handle apparatus 200 provided in the embodiment of the second aspect of this application. A base 1 is arranged on a vehicle door body. The lock cylinder 101 is arranged on the vehicle door body. One of the lock cylinder 101 and the vehicle door body is provided with a guide groove. An input end of the door lock push rod 9 is connected to a rotating arm 6 that is fastened and connected to the crankshaft 3. An output end of the door lock push rod 9 is arranged in the guide groove. When the output end of the door lock push rod 9 moves in the guide groove, at least unlocking of the vehicle door may be implemented.
According to the vehicle door provided in the embodiment of this application, unlocking reliability of the vehicle door is improved by using the foregoing handle apparatus 200.
A vehicle according to an embodiment of a fourth aspect of this application includes the vehicle door provided in the embodiment of the third aspect of this application.
According to the vehicle provided in the embodiment of this application, the user experience is improved by using the foregoing vehicle door.
The handle apparatus 200 provided in the embodiment of this application is described in detail with reference to FIG. 1 to FIG. 9 in a specific embodiment. It will be understood that the following description is only an exemplary illustration and not a specific limitation of this application.
In this embodiment, as shown in FIG. 1 to FIG. 9, a handle apparatus 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 abutting member 5, a first matching member 31, and a first reset member 7. The abutting member 5 and the first matching member 31 are fastened to the crankshaft 3. Two ends of the first reset member 7 are fastened to the base 1 and the first matching 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 same. The other end of the first link 431 is connected to one end of the second link 432 and rotatably cooperates with the same. The other end of the second link 432 is fastened to the rotating member 42 and rotates together with the rotating member 42. The rotating member 42 is provided with a second matching member 41 and a second reset member 8. Two ends of the second reset member 8 are fastened to the base 1 and a slot structure 432a of the second link 432. One end, opposite to the first matching member 31, of the crankshaft 3 is fastened and connected to the rotating arm 6. One end, away from the crankshaft 3, of the rotating arm 6 is connected to a door lock push rod 9 and rotatably cooperates with the same.
The handle apparatus 200 has an initial locked state, an ejected 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 ejected 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. Certainly, when the handle 2 is in the initial locked state and the ejected 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.
In the initial locked state, the first matching member 31 and the second matching member 41 are spaced apart, and a spacing distance between the first matching member 31 and the second matching member 41 is a preset spacing distance. When the handle 2 is switched from the initial locked state to the ejected state, the handle 2 drives the first link 431 to move in a direction away from the base 1. The first link 431 drives the second link 432 to rotate toward the handle 2. The second link 432 drives the rotating member 42 to rotate relative to the base 1, driving the second matching member 41 to rotate toward the first matching member 31. After the second matching member 41 completes an idle stroke (the gap between the first matching member 31 and the second matching member 41), the second matching member 41 is in contact with the first matching member 31 to prepare for an unlocking process.
When the handle 2 is switched from the ejected state to the unlocked state, the user pulls the handle 2 to continue to drive the first link 431 to move in a direction away from the base 1. The first link 431 drives the second link 432 to rotate toward the handle 2. The second link 432 continues to drive the rotating member 42 to rotate relative to the base 1, driving the second matching member 41 to rotate toward the first matching member 31. The second matching member 41 drives the first matching member 31 to rotate around the crankshaft 3. The crankshaft 3 rotates with the first matching member 31 to drive the rotating arm 6 to rotate in a direction away from the base 1. The rotating arm 6 rotates to drive the door lock push rod 9 to move in a direction away from the base 1. The door lock push rod 9 moves to drive the lock cylinder 101 to retract to implement unlocking.
When the user releases the handle 2, a reset torque of the first reset member 7 drives the crankshaft 3 to rotate. The crankshaft 3 rotates to drive the first matching member 31 and the abutting member 5 to rotate toward the base 1 until the abutting member 5 abuts against the base 1. In this case, the first matching member 31 is restored to an initial position, and meanwhile, a reset torque of the second reset member 8 drives the rotating member 42 to rotate in a direction away from the first link 431. The rotating member 42 rotates to drive the second matching member 41 and the second link 432 to rotate in a direction away from the first matching member 31. The second link 432 rotates to drive the first link 431 to move toward the rotating member 42. The first link 431 moves to drive the handle 2 to move toward the base 1 until the handle 2 is switched from the unlocked state to the ejected state. In this case, the second matching member 41 moves to a position of the second matching member 41 when the handle 2 is in the ejected state.
When the handle 2 is switched from the ejected 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 drive the second link 432 to rotate. The second link 432 rotates to drive the rotating member 42 to rotate in a direction away from the first link 431 and reset. The rotating member 42 rotates to drive the second matching member 41 to restore to the initial position. In this case, the first matching member 31 and the second matching member 41 are spaced at a preset spacing distance, so that the handle apparatus 200 completes a cycle from unlocking to mechanism resetting.
Referring to FIG. 10 to FIG. 13, an embodiment of this application provides a handle apparatus 200. The handle apparatus 200 may be applied to a vehicle. The handle apparatus 200 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. 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 may be driven to rotate through the transmission assembly. The handle apparatus 200 including the handle 2 is capable of driving the rotating member 42 to rotate. 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 driving the transmission shaft 110 to rotate.
Referring to FIG. 10 and FIG. 11, an input end of the door lock push rod 9 is connected to an output end of the transmission shaft 110. The transmission shaft 110 is capable of driving the door lock push rod 9 to move to unlock a lock 201.
Referring to FIG. 12 and FIG. 13, when the handle 2 is pulled in a Y direction, the rotating member 42 may be driven to rotate through the transmission assembly. When the rotating member 42 rotates, the transmission shaft 110 may be driven to rotate. The transmission shaft 110, when in rotation, is capable of pushing 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 facilitating stable connection between the door lock push rod 9 and the lock 201 when the push rod is moving. Unlocking of the lock 201 is implemented through the door lock push rod 9. The handle apparatus 200 provided in the embodiment of this application uses the transmission assembly 100 to implement connection and transmission between the handle 2 and the door lock push rod 9, avoiding a large space occupied by a pull wire mechanism between a conventional door lock and a handle, simplifying a structure of the handle apparatus 200, and improving assembly efficiency of the handle apparatus 200.
In addition, transmission between the handle 2 and the door lock push rod 9 is implemented through the transmission assembly 100, thereby avoiding friction between components inside the handle apparatus 200, and reducing noise of the handle apparatus 200 during unlocking and locking.
The handle apparatus 200 provided in the embodiment of this application includes the handle 2, the transmission assembly 100, and the door lock push rod 9. The transmission assembly 100 includes the rotating member 42 and the 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 may be driven to rotate through the transmission assembly. The handle apparatus 200 including the handle 2 is capable of driving the rotating member 42 to rotate. 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 driving the transmission shaft 110 to rotate. 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 driving the door lock push rod 9 to move to unlock the lock 201. The handle apparatus 200 uses the transmission assembly 100 to implement transmission between the handle 2 and the door lock push rod 9, which simplifies a structure of the handle apparatus 200 and improves assembly efficiency and unlocking reliability of the handle apparatus 200.
Optionally, the transmission assembly further includes a steering mechanism. The steering mechanism at least includes a first matching member 31 and a second matching member 41. The first matching member 31 is arranged on the transmission shaft 110. The second matching member 41 is arranged on the rotating member 42. A transmission angle is formed between a rotation axis of the second matching member 41 and a rotation axis of the first matching member 31.
Specifically, because there are many parts that cooperate with each other at a position for arrangement of the handle apparatus 200 on the vehicle, to make full use of an assembly space of the handle apparatus 200, arrangement 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 in different directions and the transmission shaft 110, the rotating member 42 and the transmission shaft 110 may be connected through the steering mechanism. For example, the second matching member 41 is connected to the rotating member 42. The first matching member 31 is connected to the transmission shaft 110. A rotation axis of the rotating member 42 is also the rotation axis of the second matching member 41. A rotation axis of the transmission shaft 110 is also the rotation axis of the first matching member 31. Therefore, when a transmission angle is formed between the rotating member 42 and the transmission shaft 110, that is, a transmission angle is formed between the rotation axis of the first matching member 41 and the rotation axis of the second matching member 31, stable transmission between the rotating member 42 and the transmission shaft 110 may still be ensured.
Optionally, referring to FIG. 10 and FIG. 11, the second matching member 41 is one of a cam 311 and a protrusion 413. The first matching member 31 is the other of the cam and the protrusion. The second matching member 41 is fastened to the output end of the rotating member 42. The first matching member 31 is fastened to the input end of the transmission shaft 110.
During rotation of the rotating member, the second matching member 41 is capable of contacting the first matching member 31, so that the second matching member 41 drives the first matching member 31 to rotate.
Specifically, in one embodiment, the second matching member 41 is a protrusion 413. The first matching 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 may be driven to rotate. Because the protrusion 413 cooperates with the cam 311, the protrusion 413, when in rotation, may drive the cam 311 to rotate. When the cam 311 and the transmission shaft 110 rotate synchronously, the door lock push rod 9 may be driven to move through a transmission connection between the transmission shaft 110 and the door lock push rod 9, and unlocking of the lock 201 may be implemented through the rotation of the transmission shaft 110, thereby improving unlocking efficiency of the handle apparatus 200.
In another embodiment, the second matching member 41 is a cam 311, and the first matching member 31 is a protrusion 413. Similarly, the transmission shaft 110 may push the door lock push rod 9 to move by means of cooperation between the protrusion 413 and the cam 311.
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 fastened to the input end of the transmission shaft 110. The second bevel gear is fastened to the output end of the rotating member 42. The second bevel gear is engaged with the first bevel gear.
The rotating member 42, when in rotation, drives the second bevel gear to rotate, and the second bevel gear is capable of driving the first bevel gear and the transmission shaft 110 to rotate synchronously.
Specifically, when the handle 2 is pulled, the rotating member 42 and the second bevel gear on the rotating member 42 may be driven to rotate. Because the second bevel gear cooperates with the first bevel gear, the second bevel gear, when in rotation, may drive the first bevel gear to rotate. When the first bevel gear and the transmission shaft 110 rotate synchronously, the door lock push rod 9 may be driven to move through a transmission connection between the transmission shaft 110 and the door lock push rod 9, and unlocking of the lock 201 may be implemented through the rotation of the transmission shaft 110, thereby improving unlocking efficiency of the handle apparatus 200.
Optionally, the included angle for transmission is greater than 0 degrees and less than 180 degrees.
Specifically, to make full use of an assembly space of the handle apparatus 200 when the rotating member 42 and the transmission shaft 110 are assembled, the rotating member 42 and the transmission shaft 110 may be connected through the steering mechanism to form the transmission angle between the rotating member 42 and the transmission shaft 110 on the basis of ensuring transmission stability of the rotating member 42 and the transmission shaft 110.
The transmission angle may be specifically an acute angle, a right angle, or an obtuse angle. In one implementation, referring to FIG. 10, the rotating member 42 and the transmission shaft 110 are perpendicular to each other, so that the transmission angle is a right angle.
Optionally, referring to Fig. 10 and Fig. 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 the input end of the door lock push rod 9.
Specifically, when the cam 311 of the steering mechanism is connected to the rotating arm 6 through the crankshaft 3, rotation of the cam 311 may 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 may be pushed to move during the rotation of the rotating arm 6, to unlock the lock 201 through the door lock push rod 9.
Optionally referring to FIG. 10, the handle apparatus 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.
Specifically, when the crankshaft 3 transmits rotation of the cam 311 to the rotating arm 6, the crankshaft 3 needs to be capable of rotating stably. The base 1 may serve as a substrate of the handle 2. The mounting wall 131 is provided with a through hole. The crankshaft 3 passes through the through hole and can rotate relative to the mounting wall 131, to improve rotation flexibility of the crankshaft 3 on the basis of ensuring arrangement stability of the crankshaft 3.
Optionally, referring to FIG. 10 and FIG. 11, the handle apparatus 200 further includes a first reset member 7. The first reset member 7 is connected to the crankshaft 3 and is configured to drive the crankshaft 3 to reset after unlocking is implemented by the door lock push rod 9.
Specifically, because the handle apparatus 200 needs to be frequently unlocked and locked, after unlocking of the lock 201 is implemented through the door lock push rod 9 when the transmission shaft 110 rotates, for ease of next unlocking of the handle apparatus 200, the first reset member 7 may drive the crankshaft 3 to reset to a locked position before unlocking, which can not only lock the handle apparatus 200, but also facilitate next unlocking of the handle apparatus 200.
For example, when the handle apparatus 200 is applied to unlocking and locking of a vehicle door, the handle apparatus 200 may be convenient for a user to open the vehicle door after being unlocked. When the user gets in the vehicle and closes the vehicle door, the first reset member 7 may drive the crankshaft 3 to reset to the locked position before unlocking to lock the vehicle door.
Optionally, the first reset member is a torsion spring. One end of the torsion spring is fastened and connected to the base. The other end of the torsion spring is connected and arranged on a side of the first matching member 31 away from the second matching member 41.
Specifically, the torsion spring may be sleeved on the crankshaft 3. When the crankshaft 3 rotates together with the first matching member 31, because a position of the base is relatively fastened, the first matching member 31 may drive the torsion spring to rotate and deform elastically. When the lock 201 needs to be locked after being unlocked, an elastic restoring force of the torsion spring may drive the first matching member 31 and the crankshaft 3 to rotate in an opposite direction together, so that the transmission shaft 110 is reset to the locked position before unlocking.
In one implementation, referring to FIG. 12 and FIG. 13, the first reset member 7 includes a first torsion spring and a second torsion spring. The base 1 is provided with two mounting walls 131 parallel to each other. The first torsion spring and the second torsion spring are both sleeved on 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 matching 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.
The crankshaft 3 may sequentially pass through the two mounting walls 131 parallel to each other. When the crankshaft 3 rotates together with the first matching member 31 and the rotating arm 6, because positions of the mounting walls 131 are relatively fastened, the first matching member 31 and the rotating arm 6 may drive the first torsion spring and the second torsion spring to rotate and deform elastically. When the lock 201 needs to be locked after unlocking, elastic restoring forces of the first torsion spring and the second torsion spring may drive the first matching member 31, the crankshaft 3, and the rotating arm 6 to rotate in an opposite direction together, so that the transmission shaft 110 is reset to the locked position before unlocking.
In addition, the first reset member 7 may alternatively be a unidirectional motor. Resetting of the crankshaft 3 may be implemented through the unidirectional motor.
Optionally, the handle apparatus 200 further includes an ejection assembly. The handle apparatus 200 is configured to connect a door mounting support 203. The ejection assembly is connected to the handle 2.
When the lock 201 is in an unlocked state, the ejection assembly is capable of ejecting the handle 2 from the door mounting support 203.
When the lock 201 is in a locked state, the handle 2 is flush with the door mounting support 203.
Specifically, with the lock 201 in the unlocked state, when the handle 2 is pulled, the rotating member 42 may be driven to rotate through the transmission assembly. The rotating member 42, when in rotation, may drive the transmission shaft 110 to rotate. The transmission shaft 110, when in rotation, is capable of pushing the door lock push rod 9 to move, to unlock the lock 201 through the door lock push rod 9. For ease of pulling of the handle 2, the handle 2 can be ejected from the door mounting support 203 through the ejection assembly, so that the user can apply a pulling force on the handle 2.
When the lock 201 is in the locked state, the first reset member 7 may drive the transmission shaft 110 to reset to the locked position before unlocking. The transmission shaft 110, when in resetting, may drive the handle 2 to retract through the rotating member 42. For example, the handle 2 retracts to be flush with an outer side of the door mounting support 203, to implement design of a hidden handle apparatus 200, so that the handle apparatus 200 is integrated with entire vehicle styling, and appearance of the vehicle is improved.
In one embodiment, the unlocked state of the lock 201 includes a first unlocked stage and a second unlocked stage.
Referring to FIG. 12, with the lock 201 in the first unlocked stage, an out-pull gap 202 is formed between the handle 2 and the door mounting support 203. Specifically, the handle 2 may be ejected from the door mounting support 203 through the ejection assembly, to form the out-pull gap 202 between the handle 2 and the door mounting support 203.
Referring to FIG. 13, with the lock 201 is in the second unlocked stage, when the user pulls the handle 2 outward through the out-pull gap 202, the handle 2 is capable of driving the rotating member 42 to rotate, so that the rotating member 42 drives the transmission shaft 110 to rotate. The transmission shaft 110, when in rotation, is capable of pushing the door lock push rod 9 to move, to unlock the lock 201 through the door lock push rod 9. When the transmission shaft 110 rotates, the first reset member 7 may be driven to deform, so that the first reset member 7 is in an elastically deformed state.
Optionally, with the lock 201 in the locked state, the first reset member 7 drives the transmission shaft 110 to rotate in an opposite direction to reset the transmission shaft 110.
Specifically, the first reset member 7 in the elastically deformed state may drive the transmission shaft 110 to rotate in the opposite direction through an elastic rebound force of the first reset member, to reset the transmission shaft 110. Furthermore, the transmission shaft 110, when rotating in the opposite direction, is capable of driving the rotating member 42 to rotate in the opposite direction, and then the rotating member 42 drives the handle 2 to retract and reset, so that the handle 2 is flush with the door mounting support 203.
An embodiment of this application further provides a vehicle. The vehicle includes the handle apparatus 200 and a lock 201. The lock 201 is provided with a guide groove. An output end of the door lock push rod is arranged in the guide groove.
Specifically, each door of the vehicle may be provided with one handle apparatus 200. The handle 2 of the handle apparatus 200 is connected to the rotating member 42 and is capable of driving the rotating member 42 to move. The transmission shaft 110 is connected to the rotating member 42. When the rotating member 42 moves, the transmission shaft 110 may be driven to rotate. When the output end of the door lock push rod is arranged in the guide groove, the door lock push rod 9 may be convenient for stably connecting to the lock 201 when in moving. The handle apparatus 200 uses the transmission assembly 100 to implement transmission between the handle 2 and the door lock push rod 9, which simplifies a structure of the handle apparatus 200, improves assembly efficiency of the handle apparatus 200, and ensures locking and unlocking efficiency and safety of the door on the vehicle.
