A vehicle door handle, vehicle door and vehicle

Abstract

The application provides a vehicle door handle, a vehicle door and a vehicle, and belongs to the technical field of vehicles. The vehicle door handle comprises a handle assembly, a transmission member, a position limiter and a sensing assembly. The transmission member is connected with the handle assembly and a door lock pull wire respectively, and the sensing assembly is connected with a motor of the door lock. When a user performs electric unlocking, the sensing assembly can control the motor to drive the door lock to unlock. When the user performs mechanical unlocking, the transmission member can transmit the rotation of the handle assembly to the door lock pull wire through its own movement, so that the door lock pull wire pulls the door lock to unlock. The position limiter is powered on the sensing assembly, and the movement of the transmission member is limited, so that the handle assembly cannot move the pull wire through the transmission member. When the position limiter is powered off the sensing assembly, the limitation on the transmission member is removed, the user can move the pull wire by pulling the handle assembly, and then mechanical unlocking is realized. The application avoids the occurrence of secondary unlocking of the door lock, improves the user experience of using the vehicle, and reduces the wear of the door lock.

Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a door handle, a door, and a vehicle. Background Technology

[0002] With the development of vehicle intelligence, more and more vehicles are equipped with door handles that offer both electric and mechanical unlocking methods. Under normal vehicle use, the door lock motor is activated by a control signal triggered by the user to achieve electric unlocking. In the event of an accident and power loss, the door handle is pulled to activate the door lock cable for mechanical unlocking.

[0003] In the relevant technologies, the use of mechanical unlocking methods is not restricted under normal vehicle use. After a user triggers the control signal to electrically unlock the door, pulling the handle to open the door may cause the door handle to turn, which could then pull the cable and unlock the door lock a second time. This would reduce the user's driving experience and accelerate the wear and tear on the door lock. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] With the development of vehicle intelligence, more and more vehicles are equipped with door handles that offer both electric and mechanical unlocking methods. Under normal vehicle use, the door lock motor is activated by a control signal triggered by the user to achieve electric unlocking. In the event of an accident and power loss, the door handle is pulled to activate the door lock cable for mechanical unlocking.

[0021] In the relevant technologies, the use of mechanical unlocking methods is not restricted under normal vehicle use. After a user triggers the control signal to electrically unlock the door, pulling the handle to open the door may cause the door handle to turn, which could then pull the cable and unlock the door lock a second time. This would reduce the user's driving experience and accelerate the wear and tear on the door lock.

[0022] Based on this, this application proposes a car door handle, a car door, and a vehicle to solve the problem of how to prevent secondary unlocking of the door lock. The car door handle described in this application includes a handle assembly, a transmission component, a limiter, and a sensing component. The transmission component is connected to both the handle assembly and the door lock cable, and the sensing component is connected to the door lock motor. When the user performs an electric unlock, the sensing component controls the motor to drive the door lock to unlock. When the user performs a mechanical unlock, the transmission component can transmit the rotation of the handle assembly to the door lock cable through its own movement, causing the door lock cable to pull the door lock to unlock. When the sensing component is energized, i.e., during normal vehicle use, the limiter restricts the movement of the transmission component, preventing the handle assembly from pulling the cable via the transmission component. When the sensing component is de-energized, i.e., in the event of an accident, the limiter releases its restriction on the transmission component, allowing the user to pull the handle assembly to move the cable, thereby achieving mechanical unlocking. This application uses a limiter to restrict the use of mechanical unlocking during normal vehicle use, preventing mechanical unlocking even when the user pulls the handle. This avoids secondary unlocking of the door lock, improves the user experience, and reduces wear and tear on the door lock. Specifically, it includes: The first aspect of this application provides an embodiment, such as... Figure 1 The schematic diagram shown is a cross-sectional view of a car door handle. The car door handle includes: Base assembly 1, connected to the door sheet metal; Handle assembly 2, one end of which is hinged to base assembly 1; Transmission component 3 is mounted on base assembly 1. Transmission component 3 is connected to the end of handle assembly 2 away from the hinge end and the pull cable of door lock respectively. The sensing component 4 is connected in communication with the motor of the door lock and is used to control the motor to drive the door lock to unlock. Limiter 5 is mounted on base assembly 1; When the sensing component 4 is powered on, the limiter 5 restricts the movement of the transmission component 3; when the sensing component 4 is powered off, the limiter 5 releases its restriction on the transmission component 3, so that the transmission component 3 moves relative to the base component 1 when the handle component 2 is rotated, thereby driving the pull cable to unlock the door lock.

[0023] The base assembly 1 is connected to the door sheet metal. To enhance the aesthetics of the vehicle's appearance, the base assembly 1 can be housed within a cavity inside the door, connected to the side of the door sheet metal closest to the cavity. In an optional embodiment, the base assembly 1 can be installed on the door sheet metal using a combination of bolts and snap-fit ​​connections.

[0024] One end of the handle assembly 2 is hinged to the base assembly 1, allowing the handle assembly 2 to rotate around the hinged end. A transmission component 3 is mounted on the base assembly 1 and is connected to both the end of the handle assembly 2 furthest from the hinged end and the door lock cable. When the transmission component 3 is in an unrestricted state, the user pulls the handle assembly 2, causing the end of the handle assembly 2 furthest from the hinged end to rotate around the hinged end. This rotation drives the transmission component 3, which in turn transmits the motion of the handle assembly 2 to the cable, thereby unlocking the door lock.

[0025] In addition to mechanical unlocking via a pull cable, the door lock can also be electrically unlocked via a motor. The sensing component 4 is communicatively connected to the door lock's motor. When the user needs to unlock electrically, the sensing component 4 sends a corresponding control signal to the door lock's motor, controlling the motor's output to rotate, thereby driving the lock's bolt out of the lock slot to unlock. In an optional implementation, the user can send an opening signal to the sensing component 4 via a smart key, triggering the sensing component 4 to control the motor to unlock the door.

[0026] Limiter 5 is mounted on base assembly 1. When sensor assembly 4 is powered on and limiter 5 restricts the movement of transmission component 3, when the user pulls handle assembly 2 after electric unlocking, transmission component 3 cannot drive the cable to mechanically unlock the door lock due to the limitation of limiter 5. When sensor assembly 4 is powered off and limiter 5 is no longer restricting transmission component 3, when the user pulls handle assembly 2, transmission component 3 drives the cable to move under the drive of handle assembly 2, thereby mechanically unlocking the door lock.

[0027] Optionally, the base assembly 1 is provided with a connecting shaft 11, and the transmission component 3 includes a rocker arm 31; The rocker arm 31 includes a first connecting part 311, a second connecting part 312, and a connecting hole 313, with the first connecting part 311 and the second connecting part 312 located on both sides of the connecting hole 313. The first connecting part 311 is connected to the end of the handle assembly 2 away from the hinge end, the second connecting part 312 is connected to the pull wire, and the connecting hole 313 is sleeved on the connecting shaft 11.

[0028] The transmission component 3 can transmit the movement of the handle assembly 2 to the pull cable by rotation. (Reference) Figure 2The diagram shows a partial structure of a car door handle. The transmission component 3 includes a rocker arm 31, which comprises a first connecting portion 311, a second connecting portion 312, and a connecting hole 313. The base assembly 1 is provided with a connecting shaft 11. The connecting hole 313 of the rocker arm 31 is fitted onto the connecting shaft 11, allowing the rocker arm 31 to rotate about the connecting shaft 11. The first connecting portion 311 of the rocker arm 31 is connected to the end of the handle assembly 2 away from the hinge end, and the second connecting portion 312 is connected to a pull cable. When the handle assembly 2 is pulled, the handle assembly 2 drives the rocker arm 31 to rotate via the first connecting portion 311, thereby causing the second connecting portion 312 to rotate along with the first connecting portion 311, causing the pull cable to unlock the door lock.

[0029] Optionally, the limiter 5 includes: a return spring 51, the initial torque of which is greater than a preset threshold. The reset spring 51 is sleeved on the connecting shaft 11. One end of the reset spring 51 abuts against the rocker arm 31, and the other end abuts against the base assembly 1.

[0030] The limit switch 5 includes a return spring 51. (See reference) Figure 2 The diagram shows a partial structure of a car door handle. A return spring 51 is sleeved on the connecting shaft 11 of the base assembly 1, with one end abutting against the rocker arm 31 and the other end abutting against the base assembly 1. When the user pulls the handle assembly 2, causing the rocker arm 31 to rotate, the return spring 51 deforms, converting part of the kinetic energy of the rocker arm 31 into the elastic potential energy of the return spring 51. After mechanical unlocking is completed, the user releases the handle, the elastic potential energy stored in the return spring 51 is released, driving the rocker arm 31 to rotate and causing the handle assembly 2 to reset.

[0031] The initial torque refers to the torque of the return spring 51 when the door handle is in its initial state without any external force. In one optional embodiment, the preset threshold can be 900 N·mm, or the preset threshold can be a value greater than 900 N·mm.

[0032] When the sensing component 4 is powered on, it automatically controls the motor to unlock the door when the user opens the door. Subsequently, the user pulls the door handle, which opens the door. At this time, because the initial torque of the return spring 51 is greater than the torque that the door needs to overcome to open, the torque exerted by the handle assembly 2 on the rocker arm 31 cannot counteract the initial torque of the return spring 51, thereby limiting the movement of the rocker arm 31 and keeping the rocker arm 31 relatively stationary with respect to the base assembly 1 during the door opening process.

[0033] When the sensor component 4 is de-energized, the user cannot unlock the door electrically and can only unlock it mechanically by pulling the handle component 2. Initially, when the user pulls the handle component 2, the door remains relatively stationary with respect to the vehicle body under the action of the door lock, and the force applied by the user to the handle component 2 overcomes the initial torque of the return spring 51. When the force applied by the user to the handle component 2 causes the torque of the rocker arm 31 to exceed the initial torque, the return spring 51 releases its restraint on the rocker arm 31, causing the rocker arm 31 to rotate relative to the base component 1 under the drive of the handle component 2, thereby driving the cable to achieve mechanical unlocking.

[0034] Optionally, the base assembly 1 includes a base 12 and a fixed seat 13 rotatably connected to the base 12, and the base 12 is connected to the door sheet metal; The handle assembly 2 is provided with a connector 211 at the hinge end; The base 12 is provided with a through hole 121, the connector 211 is located inside the through hole 121, and the end of the fixing seat 13 connected to the base 12 is located outside the through hole 121. The fixing seat 13 extends from the outside of the through hole 121 to the inside of the through hole 121, and the end of the fixing seat 13 away from the base 12 is rotatably connected to the connector 211.

[0035] refer to Figure 3 An exploded view of a car door handle is shown. Figure 4 A schematic diagram of the external structure of a car door handle is shown, and Figure 5 The diagram shows a top view of a door handle base. The base assembly 1 includes a base 12 and a mounting base 13, with the base 12 rotatably connected to the mounting base 13. The base 12 is connected to the door sheet metal, and the mounting base 13 is connected to the hinge end of the handle assembly 2. The handle assembly 2 has a connector 211 at the hinge end. The base 12 has a through hole 121, with the connector 211 located inside the through hole 121, i.e., within the cavity of the through hole 121. One end of the mounting base 13, connected to the base 12, is located outside the through hole 121. The mounting base 13 extends from the outside of the through hole 121 to the inside of the through hole 121, and the end of the mounting base 13 furthest from the base 12 is rotatably connected to the connector 211.

[0036] When the handle assembly 2 is rotated, the handle assembly 2 rotates relative to the fixed seat 13, and drives the fixed seat 13 to rotate relative to the base 12, thereby realizing the hinged connection between the handle assembly 2 and the base assembly 1.

[0037] Optionally, the connector 211 is provided with a snap-fit ​​shaft a, and the end of the fixed base 13 away from the base 12 is provided with a snap-fit ​​hole 131, and the snap-fit ​​shaft a is rotatably snapped into the snap-fit ​​hole 131.

[0038] refer to Figure 4An exploded view of a car door handle is shown. To facilitate the installation of the handle assembly 2 and the base assembly 1, the connector 211 and the fixing seat 13 can be connected by a snap-fit ​​mechanism. When installing the handle assembly 2, the connector 211 of the handle assembly 2 is first inserted into the through hole 121 of the base 12. Then, the fixing seat 13 is rotated so that the end of the fixing seat 13 away from the base 12 rotates towards the inside of the through hole 121. This causes the snap-fit ​​shaft a on the connector 211 to snap into the snap-fit ​​hole 131 located at the end of the fixing seat 13 away from the base 12, thus achieving quick installation of the handle assembly 2 and the base assembly 1.

[0039] Optionally, the handle assembly 2 includes a handle frame 22 and a handle housing 22 covering the handle frame 22; The handle frame 22 and the handle housing 22 together form a storage cavity, and the sensing component 4 is located inside the storage cavity.

[0040] To improve the integration of the door handle, the sensor component 4 can be integrated into the handle assembly 2. The handle assembly 2 includes a handle frame 22 and a handle housing 22 covering the handle frame 22. The handle housing 22 and the handle frame 22 together form a storage cavity to house the sensor component 4. In an optional embodiment, the position of the sensor component 4 can be restricted by limiting ribs and supporting ribs provided on the inner wall of the storage cavity, thereby fixing the sensor component 4 within the storage cavity.

[0041] Optionally, the sensing component 4 includes a capacitor module 41 and a control module 42 connected to the capacitor module 41, the control module 42 being communicatively connected to the motor; Capacitor module 41 is used to send a capacitor signal to control module 42 in response to the user's touch of the door handle; The control module 42 is used to control the motor to drive the door lock to unlock when a capacitor signal is received.

[0042] To improve the automation of electric door unlocking, the user's touch on the handle assembly 2 can trigger the sensing component 4 to control the motor and unlock the door lock. Specifically, the sensing component 4 consists of a capacitor module 41 and a control module 42. The capacitor module 41 should be located on the handle assembly 2. When the user touches the handle assembly 2, the capacitance value of the capacitor module 41 increases, and the increased capacitance value is transmitted to the control module 42 via a capacitance signal.

[0043] When the control module 42 receives the capacitor signal, it sends a control signal to the motor to control the motor to unlock the door lock. In an optional embodiment, to improve the accuracy of electric unlocking and avoid mis-locking, the step of the control module 42 sending a control signal to the motor in response to the capacitor signal can be further defined. For example, the control module 42 sends a control signal to the motor only after receiving the capacitor signal several times consecutively, such as eight times.

[0044] Optionally, the door handle also includes a cushioning pad 6, which is located at the end of the handle assembly 2 away from the hinge end and is fitted to the side of the handle assembly 2 near the base assembly 1.

[0045] To prevent damage to the paint surface of the door panel when the handle assembly 2 resets after the user releases it, a buffer pad 6 can be added to the door handle. The buffer pad 6 is located at the end of the handle assembly 2 that moves relative to the door, i.e., the end away from the hinge end, and is in contact with the side of the handle assembly 2 closest to the base 12. In an optional embodiment, the buffer pad 6 can be made of an elastic material such as silicone or rubber.

[0046] In one alternative implementation, to prevent water from entering the car door and improve the airtightness between the door handle and the door sheet metal, a sealing gasket can be provided between the base assembly 1 and the door sheet metal.

[0047] The second aspect of this application provides a door handle, as shown in the reference. Figures 1 to 5 The door handle includes: The system includes a base assembly 1, a return spring 51, a rocker arm 31, a handle assembly 2, and a sensing assembly 4. The base assembly 1 includes a base 12 and a fixing seat 13, the handle assembly 2 includes a handle frame 22 and a handle housing 22, and the sensing assembly 4 includes a capacitor module 41 and a control module 42.

[0048] The base 12 is provided with a connecting shaft 11. The rocker arm 31 includes a first connecting part 311, a second connecting part 312, and a connecting hole 313. The first connecting part 311 and the second connecting part 312 are located on both sides of the connecting hole 313. The first connecting part 311 is connected to the end of the handle assembly 2 away from the hinge end, the second connecting part 312 is connected to the pull cable, and the connecting hole 313 is fitted onto the connecting shaft 11.

[0049] The initial torque of the return spring 51 is greater than a preset threshold. The return spring 51 is sleeved on the connecting shaft 11, with one end abutting against the rocker arm 31 and the other end abutting against the base assembly 1. In an optional embodiment, the preset threshold may be 900 N·mm, or a value greater than 900 N·mm.

[0050] The fixed seat 13 is rotatably connected to the base 12, and the base 12 is connected to the door sheet metal. The handle frame 22 is hinged to the end of the fixed seat 13 away from the base 12. The hinged end of the handle frame 22 is provided with a connector 211, and a locking shaft a is provided on the connector 211. The base 12 is provided with a through hole 121, the connector 211 is located inside the through hole 121, and the end of the fixed seat 13 connected to the base 12 is located outside the through hole 121. The fixed seat 13 extends from the outside of the through hole 121 to the inside of the through hole 121. The end of the fixed seat 13 away from the base 12 is provided with a locking hole 131, and the locking shaft a is rotatably locked with the locking hole 131.

[0051] Capacitor module 41 is connected to control module 42, and control module 42 is communicatively connected to the motor. Capacitor module 41 sends a capacitance signal to control module 42 in response to a user touching the door handle. Upon receiving the capacitance signal, control module 42 controls the motor to unlock the door.

[0052] The handle frame 22 and the handle housing 22 together form a storage cavity, and the capacitor module 41 and the control module 42 are located inside the storage cavity.

[0053] The door handle also includes a buffer pad 6, which is located at the end of the handle assembly 2 away from the hinge end and is attached to the side of the handle assembly 2 near the base assembly 1.

[0054] When the capacitor module 41 is powered on, and the user touches the door handle, the capacitor module 41 responds to the user's touch by sending a capacitor signal to the control module 42. Upon receiving the capacitor signal, the control module 42 controls the motor to drive the door lock to unlock, thereby achieving electric unlocking.

[0055] After the door lock is electrically unlocked, the user pulls the door to open it. At this time, since the initial torque of the return spring 51 is greater than the torque that needs to be overcome to open the door, the torque of the handle assembly 2 on the rocker arm 31 cannot counteract the initial torque of the return spring 51, thereby restricting the movement of the rocker arm 31 and keeping the rocker arm 31 relatively stationary with respect to the base assembly 1 during the opening of the door.

[0056] When the capacitor module 41 is powered off, the user cannot unlock the door electrically by touching the door handle; instead, they can only unlock it mechanically by pulling the handle assembly 2. Initially, when the user pulls the handle assembly 2, the door remains relatively stationary with respect to the vehicle body under the action of the door lock, and the force applied by the user to the handle assembly 2 overcomes the initial torque of the return spring 51. When the force applied by the user to the handle assembly 2 causes the torque of the rocker arm 31 to exceed the initial torque, the return spring 51 releases its restraint on the rocker arm 31, causing the rocker arm 31 to rotate relative to the base assembly 1 under the drive of the handle assembly 2, thereby driving the pull cable to achieve mechanical unlocking.

[0057] A third aspect of this application provides for a vehicle door, which includes the door handle of this application.

[0058] The fourth aspect of this application provides for a vehicle that includes the door handle of this application, or a door that includes the door of this application.

[0059] The door handle of this application includes a handle assembly 2, a transmission component 3, a limiter 5, and a sensor component 4. The transmission component 3 is connected to both the handle assembly 2 and the door lock cable, and the sensor component 4 is connected to the door lock motor. When the user performs electric unlocking, the sensor component 4 controls the motor to drive the door lock to unlock. When the user performs mechanical unlocking, the transmission component 3 can transmit the rotation of the handle assembly 2 to the door lock cable through its own movement, causing the door lock cable to pull the door lock to unlock. When the sensor component 4 is energized, i.e., during normal vehicle use, the limiter 5 restricts the movement of the transmission component 3, preventing the handle assembly 2 from pulling the cable via the transmission component 3. When the sensor component 4 is de-energized, i.e., in the event of an accident, the limiter 5 releases its restriction on the transmission component 3, allowing the user to pull the handle assembly 2 to move the cable and thus achieve mechanical unlocking. This application, through the limiter 5, restricts the use of mechanical unlocking during normal vehicle use, preventing the user from mechanically unlocking the door even when pulling the handle, thus avoiding secondary unlocking of the door lock, improving the user experience, and reducing wear and tear on the door lock.

[0060] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

[0061] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
