DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] With the development of vehicle intelligence, more and more vehicles are equipped with door handles that have both electric unlocking and mechanical unlocking. When the vehicle is in normal use, the door lock motor is controlled by the control signal triggered by the user to drive the door lock to achieve electric unlocking. When the vehicle has an accident and the power is cut off, the door lock cable is driven by pulling the door handle to unlock mechanically.

[0042] In the related art, the use of mechanical unlocking is not restricted under normal vehicle use. After the user triggers the control signal to electrically unlock the door, if the user pulls the handle to open the door, there is a possibility that the door handle will turn, driving the pull wire to unlock the door lock again, thereby reducing the user's car experience and aggravating the wear of the door lock.

[0043] Based on this, the present application proposes a door handle, a door and a vehicle to solve the problem of how to avoid the door lock from being unlocked twice. The door handle described in the present application includes a handle assembly, a transmission member, a limiter and a sensing assembly. The transmission member is connected to the handle assembly and the door lock cable respectively, and the sensing assembly is connected to the motor of the door lock. When the 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 cable through its own movement, so that the door lock cable pulls the door lock to unlock. When the sensing assembly is powered on, that is, when the vehicle is in normal use, the limiter restricts the movement of the transmission member, so that the handle assembly cannot pull the cable to move through the transmission member. When the sensing assembly is powered off, that is, when an accident occurs in the vehicle, the limiter is free from the restriction on the transmission member, and the user can drive the cable to move by pulling the handle assembly, thereby achieving mechanical unlocking. This application uses a limiter to limit the use of mechanical unlocking when the vehicle is in normal use, so that even if the user pulls the handle to open the door, mechanical unlocking cannot be achieved, avoiding the situation of secondary unlocking of the door lock, improving the user's car experience, and reducing the wear and tear of the door lock. Specifically including:

[0044] The first aspect of the present application proposes an embodiment, such as Figure 1 As shown in the schematic cross-sectional structure diagram of a door handle, the door handle comprises:

[0045] Base assembly 1, connected to the door sheet metal;

[0046] A handle assembly 2, one end of the handle assembly 2 is hinged to the base assembly 1;

[0047] The transmission member 3 is arranged on the base assembly 1, and the transmission member 3 is respectively connected to an end of the handle assembly 2 away from the hinged end and the pull wire of the door lock;

[0048] The sensing component 4 is connected to the motor of the door lock for communication, and the sensing component 4 is used to control the motor to drive the door lock to unlock;

[0049] A stopper 5, the stopper 5 is arranged on the base assembly 1;

[0050] When the sensing component 4 is powered on, the limiter 5 limits the movement of the transmission member 3; when the sensing component 4 is powered off, the limiter 5 is free from the restriction on the transmission member 3, so that the transmission member 3 moves relative to the base component 1 when the handle component 2 rotates, thereby driving the pull wire to unlock the door lock.

[0051] The base assembly 1 is connected to the door sheet metal. To improve the appearance of the vehicle, the base assembly 1 can be set in the accommodating cavity inside the door and connected to the side of the door sheet metal close to the accommodating cavity. In an optional embodiment, the base assembly 1 can be installed on the door sheet metal by bolt connection and snap connection.

[0052] One end of the handle assembly 2 is hinged to the base assembly 1, so that the handle assembly 2 can rotate around the hinged end hinged to the base assembly 1. The transmission member 3 is arranged on the base assembly 1, and is respectively connected to the end of the handle assembly 2 away from the hinged end and the pull wire of the door lock. When the transmission member 3 is in a state without movement restriction, the user pulls the handle assembly 2, so that the end of the handle assembly 2 away from the hinged end rotates around the hinged end, thereby driving the transmission member 3 to move, and the movement of the handle assembly 2 is transmitted to the pull wire through the transmission member 3, so that the pull wire drives the door lock to unlock.

[0053] In addition to mechanical unlocking through a pull-wire drive, the door lock can also be electrically unlocked through a motor. The sensing component 4 is connected to the motor of the door lock. When the user needs to electrically unlock, the sensing component 4 sends a corresponding control signal to the motor of the door lock to control the output end of the motor to rotate, thereby driving the lock tongue of the door lock to move out of the lock to unlock. In an optional embodiment, the user can send a door opening signal to the sensing component 4 through a smart key, triggering the sensing component 4 to control the motor to drive the door lock to unlock.

[0054] The limiter 5 is arranged on the base assembly 1. When the sensing assembly 4 is powered on and the limiter 5 limits the movement of the transmission member 3, when the user pulls the handle assembly 2 after the electric unlocking, the transmission member 3 cannot drive the pull wire to mechanically unlock the door lock under the restriction of the limiter 5. When the sensing assembly 4 is powered off and the limiter 5 is free from the restriction on the transmission member 3, when the user pulls the handle assembly 2, the transmission member 3 drives the pull wire to move under the drive of the handle assembly 2, thereby mechanically unlocking the door lock.

[0055] Optionally, the base assembly 1 is provided with a connecting shaft 11, and the transmission member 3 includes a rocker arm 31;

[0056] The rocker arm 31 includes a first connection portion 311, a second connection portion 312 and a connection hole 313, wherein the first connection portion 311 and the second connection portion 312 are respectively located at two sides of the connection hole 313;

[0057] The first connection portion 311 is connected to an end of the handle assembly 2 away from the hinge end, the second connection portion 312 is connected to the pull wire, and the connection hole 313 is sleeved on the connection shaft 11 .

[0058] The transmission member 3 can transmit the movement of the handle assembly 2 to the pull wire in a rotational manner. Figure 2A schematic diagram of a partial structure of a door handle is shown, in which the transmission member 3 includes a rocker arm 31, and the rocker arm 31 includes a first connection portion 311, a second connection portion 312 and a connection hole 313, and the base assembly 1 is provided with a connection shaft 11. The connection hole 313 of the rocker arm 31 is sleeved on the connection shaft 11, so that the rocker arm 31 can rotate with the connection shaft 11 as the rotation axis. The first connection portion 311 of the rocker arm 31 is connected to an end of the handle assembly 2 away from the hinge end, and the second connection portion 312 is connected to the pull wire. When the handle assembly 2 is pulled, the handle assembly 2 drives the rocker arm 31 to rotate through the first connection portion 311, and then the second connection portion 312 rotates with the first connection portion 311, so that the pull wire pulls the door lock to unlock.

[0059] Optionally, the limiter 5 comprises: a return spring 51, wherein the initial torque of the return spring 51 is greater than a preset threshold;

[0060] The return spring 51 is sleeved on the connecting shaft 11 , one end of the return spring 51 abuts against the rocker arm 31 , and the other end abuts against the base assembly 1 .

[0061] The stopper 5 includes a return spring 51. Figure 2 The schematic diagram of the partial structure of a door handle is shown, in which the 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 to drive the rocker arm 31 to rotate, the return spring 51 is deformed, and the kinetic energy of the rocker arm 31 is partially converted into the elastic potential energy of the return spring 51. After completing the mechanical unlocking, the user releases the handle, and the elastic potential energy stored in the return spring 51 is released, driving the rocker arm 31 to rotate, driving the handle assembly 2 to reset.

[0062] The initial torque refers to the torque of the return spring 51 when the door handle is in an initial state without external force. In an optional implementation, the preset threshold may be 900 N·mm, or the preset threshold may be a value greater than 900 N·mm.

[0063] When the sensing component 4 is powered on, the sensing component 4 automatically controls the motor to drive the door lock to unlock when the user opens the door. Subsequently, the user pulls the door handle to drive the door to unfold. At this time, since the initial torque of the return spring 51 is greater than the torque that needs to be overcome for the door to unfold, the torque of the handle assembly 2 on the rocker arm 31 cannot offset the initial torque of the return spring 51, thereby limiting the movement of the rocker arm 31, so that the base assembly 1 is in a relatively static state with the base assembly 1 during the process of the door unfolding.

[0064] When the sensing component 4 is powered off, the user cannot achieve electric unlocking and can only achieve mechanical unlocking by pulling the handle component 2. At this time, in the initial stage when the user pulls the handle component 2, the door remains relatively still with the vehicle body under the action of the door lock, and the force applied by the user to the handle component 2 is used to overcome the initial torque of the return spring 51. When the force applied by the user to the handle component 2 makes the torque of the rocker arm 31 greater than the initial torque, the return spring 51 breaks away from the restriction on the rocker arm 31, so that the rocker arm 31 is driven by the handle component 2 to rotate relative to the base component 1, and then drives the pull wire to achieve mechanical unlocking.

[0065] Optionally, the base assembly 1 includes a base 12 and a fixing base 13 rotatably connected to the base 12, and the base 12 is connected to the door sheet metal;

[0066] The handle assembly 2 is provided with a connector 211 at the hinged end;

[0067] The base 12 is provided with a through hole 121, the connector 211 is located inside the through hole 121, and one end of the fixing base 13 connected to the base 12 is located outside the through hole 121;

[0068] The fixing seat 13 extends from the outer side of the through hole 121 to the inner side of the through hole 121 , and one end of the fixing seat 13 away from the base 12 is rotatably connected to the connector 211 .

[0069] refer to Figure 3 An exploded structural diagram of a door handle is shown, Figure 4 A schematic diagram of the appearance structure of a door handle is shown, and Figure 5 A top view of the base of a vehicle door handle is shown. The base assembly 1 includes a base 12 and a fixed seat 13, and the base 12 is rotatably connected to the fixed seat 13. The base 12 is connected to the vehicle door sheet metal, and the fixed seat 13 is connected to the hinged end of the handle assembly 2. The handle assembly 2 is provided with a connector 211 at the hinged end, and the base 12 is provided with a through hole 121. The connector 211 is located on the inner side of the through hole 121, that is, in the cavity of the through hole 121, and one end of the fixed seat 13 connected to the base 12 is located on the outer side of the through hole 121. The fixed seat 13 extends from the outer side of the through hole 121 to the inner side of the through hole 121, and the end of the fixed seat 13 away from the base 12 is rotatably connected to the connector 211.

[0070] When the handle assembly 2 rotates, the handle assembly 2 rotates relative to the fixing seat 13 and drives the fixing seat 13 to rotate relative to the base 12, thereby realizing the hinged connection between the handle assembly 2 and the base assembly 1.

[0071] Optionally, a clamping shaft a is provided on the connector 211 , and a clamping hole 131 is provided at one end of the fixing seat 13 away from the base 12 , and the clamping shaft a is rotatably clamped with the clamping hole 131 .

[0072] refer to Figure 4 The exploded view of a vehicle 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 snapping. When installing the handle assembly 2, first put the connector 211 of the handle assembly 2 into the through hole 121 of the base 12, then rotate the fixing seat 13 so that the end of the fixing seat 13 away from the base 12 rotates toward the inner side of the through hole 121, and then the snap-in axis a on the connector 211 snaps into the snap-in hole 131 set at the end of the fixing seat 13 away from the base 12, so as to achieve quick installation of the handle assembly 2 and the base assembly 1.

[0073] Optionally, the handle assembly 2 includes a handle frame 22 and a handle housing 22 covered on the handle frame 22;

[0074] The handle frame 22 and the handle housing 24 together form a storage cavity, and the sensor component 4 is located in the storage cavity.

[0075] In order to improve the integration of the door handle, the sensing component 4 can be integrated into the handle component 2. The handle component 2 includes a handle frame 22 and a handle shell 22 covered on the handle frame 22. The handle shell 22 and the handle frame 22 together form a storage cavity, so that the sensing component 4 can be installed in the storage cavity. In an optional embodiment, the position of the sensing component 4 can be limited by the limiting ribs and supporting ribs provided on the inner wall of the storage cavity, so that the sensing component 4 is fixed in the storage cavity.

[0076] Optionally, the induction component 4 includes a capacitor module 41, and a control module 42 connected to the capacitor module 41, and the control module 42 is communicatively connected to the motor;

[0077] The capacitance module 41 is used to send a capacitance signal to the control module 42 in response to the user touching the door handle;

[0078] The control module 42 is used to control the motor to drive the door lock to unlock when receiving the capacitance signal.

[0079] In order to improve the degree of automation of electric door unlocking, the user can touch the handle assembly 2 to trigger the sensing assembly 4 to control the motor to unlock the door lock. Specifically, the sensing assembly 4 is composed 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 in the form of a capacitance signal.

[0080] When the control module 42 receives the capacitance signal, the control module 42 sends a control signal to the motor to control the motor to drive the door lock to unlock. In an optional embodiment, in order to improve the accuracy of electric unlocking and avoid misinterpretation of the lock, the step of the control module 42 sending a control signal to the motor in response to the capacitance signal can be further limited. For example, when the control module 42 receives the capacitance signal several times, such as 8 times, in succession, the control signal is sent to the motor.

[0081] Optionally, the vehicle door handle further includes a buffer pad 6 , which is located at an end of the handle assembly 2 away from the hinge end and fits with a side of the handle assembly 2 close to the base assembly 1 .

[0082] In order to prevent the paint surface of the door sheet metal from being damaged when the handle assembly 2 is reset after the user releases the handle assembly 2, 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, that is, the end away from the hinge end, and fits with the side of the handle assembly 2 close to the base 12. In an optional embodiment, the buffer pad 6 can be made of an elastic material such as silicone or rubber.

[0083] In an optional implementation, in order to prevent water from entering the vehicle door and improve the airtightness between the vehicle door handle and the vehicle door sheet metal, a sealing gasket may be provided between the base assembly 1 and the vehicle door sheet metal.

[0084] The second aspect of the present application provides a door handle, referring to Figures 1 to 5 , the door handle comprises:

[0085] Base assembly 1, return spring 51, rocker arm 31, handle assembly 2, and induction 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 induction assembly 4 includes a capacitor module 41 and a control module 42.

[0086] The base 12 is provided with a connecting shaft 11, and the rocker arm 31 includes a first connecting portion 311, a second connecting portion 312 and a connecting hole 313, wherein the first connecting portion 311 and the second connecting portion 312 are respectively located on both sides of the connecting hole 313. The first connecting portion 311 is connected to an end of the handle assembly 2 away from the hinge end, the second connecting portion 312 is connected to the pull wire, and the connecting hole 313 is sleeved on the connecting shaft 11.

[0087] The initial torque of the reset spring 51 is greater than the 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. In an optional embodiment, the preset threshold may be 900 N·mm, or the preset threshold is a value greater than 900 N·mm.

[0088] The fixing 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 fixing seat 13 away from the base 12. The hinged end of the handle frame 22 is provided with a connector 211, and the connector 211 is provided with a clamping shaft a. The base 12 is provided with a through hole 121, and the connector 211 is located on the inner side of the through hole 121. The end of the fixing seat 13 connected to the base 12 is located on the outer side of the through hole 121. The fixing seat 13 extends from the outer side of the through hole 121 to the inner side of the through hole 121. The end of the fixing seat 13 away from the base 12 is provided with a clamping hole 131, and the clamping shaft a is rotatably clamped with the clamping hole 131.

[0089] The capacitor module 41 is connected to the control module 42, and the control module 42 is connected to the motor for communication. The capacitor module 41 is used to send a capacitor signal to the control module 42 in response to the user touching the door handle. The control module 42 is used to control the motor to drive the door lock to unlock when receiving the capacitor signal.

[0090] The handle frame 22 and the handle housing 23 together form a storage cavity, and the capacitor module 41 and the control module 42 are located in the storage cavity.

[0091] The door handle further includes a buffer pad 6 , which is located at an end of the handle assembly 2 away from the hinge end and fits with a side of the handle assembly 2 close to the base assembly 1 .

[0092] When the capacitor module 41 is powered on, the user touches the door handle, and the capacitor module 41 responds to the user's action of touching the door handle and sends a capacitor signal to the control module 42. When the control module 42 receives the capacitor signal, it controls the motor to drive the door lock to unlock, thereby realizing electric unlocking.

[0093] 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 for the door to open, the torque of the handle assembly 2 on the rocker arm 31 cannot offset the initial torque of the return spring 51, thereby limiting the movement of the rocker arm 31, so that the base assembly 1 is in a relatively static state with the base assembly 1 during the door opening process.

[0094] When the capacitor module 41 is powered off, the user cannot electrically unlock the door by touching the door handle, and can only mechanically unlock the door by pulling the handle assembly 2. At this time, in the initial stage when the user pulls the handle assembly 2, the door remains relatively still with the vehicle body under the action of the door lock, and the force applied by the user to the handle assembly 2 is used to overcome the initial torque of the return spring 51. When the force applied by the user to the handle assembly 2 makes the torque of the rocker arm 31 greater than the initial torque, the return spring 51 breaks away from the restriction on the rocker arm 31, so that the rocker arm 31 rotates relative to the base assembly 1 under the drive of the handle assembly 2, and then drives the pull wire to achieve mechanical unlocking.

[0095] A third aspect of the present application provides a vehicle door, which includes the door handle of the present application.

[0096] A fourth aspect of the present application proposes a vehicle, which includes the door handle of the present application, or includes the door of the present application.

[0097] The door handle of the present application includes a handle assembly 2, a transmission member 3, a stopper 5, and a sensing assembly 4. The transmission member 3 is connected to the handle assembly 2 and the door lock cable respectively, and the sensing assembly 4 is connected to the motor of the door lock. When the user performs electric unlocking, the sensing assembly 4 can control the motor to drive the door lock to unlock. When the user performs mechanical unlocking, the transmission member 3 can transmit the rotation of the handle assembly 2 to the door lock cable through its own movement, so that the door lock cable pulls the door lock to unlock. When the sensing assembly 4 is powered on, that is, when the vehicle is in normal use, the stopper 5 limits the movement of the transmission member 3, so that the handle assembly 2 cannot be pulled by the transmission member 3 to pull the cable to move. When the sensor assembly 4 is powered off, that is, when an accident occurs in the vehicle, the stopper 5 is freed from the restriction on the transmission member 3, and the user can drive the cable to move by pulling the handle assembly 2, thereby realizing mechanical unlocking. The present application limits the use of the mechanical unlocking method through the stopper 5 when the vehicle is in normal use, so that the user cannot realize mechanical unlocking even if he pulls the handle to open the door, thereby avoiding the situation of secondary unlocking of the door lock, improving the user's car experience, and reducing the wear of the door lock.
