[0039] 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 only 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 making creative work are within the scope of protection of this application.

[0040] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0041] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Some models of vehicles have electric hidden door locks on the outside of the doors, which can be automatically unlocked by sensing gestures. The electric hidden door lock consists of a handle body and a sensing device, as well as an electric drive mechanism and a lock actuator inside the door. The trigger signal sent back by the sensing device controls the electric drive mechanism to drive the lock actuator to lock and unlock the door. However, under the influence of various factors such as freezing and collision, the electric automatic unlocking function is prone to failure, resulting in the door being unable to open, which poses a certain safety risk.

[0043] To this end, the embodiments of the present application provide a door handle assembly, a door lock device and a vehicle, which aim to improve the unlocking reliability of the electric hidden door handle to a certain extent and enhance safety.

[0044] Figure 1 A schematic structural diagram of a door handle assembly in an embodiment of the present application is shown; Figure 6 Shows Figure 1 Schematic diagram of the installation status of the inner door handle assembly.

[0045] See also Figure 1 and Figure 6 In some embodiments, the door handle assembly 1 is installed on the outside of the door 2 and is configured as an assembly with operation and sensing functional structures; and the door handle assembly 1 is connected to the door lock installed in the door 2. The door handle assembly is operated to control the door lock action to achieve unlocking, and then the door 2 can be opened.

[0046] The vehicle door handle assembly 1 includes an outer handle mechanism 11 and a sensing component 12. The outer handle mechanism 11 can be installed on the vehicle door 2, and the sensing component 12 can be arranged in the outer handle mechanism 11. The outer handle mechanism 11 and the sensing component 12 are respectively connected to the door lock to control the door lock action and implement the unlocking operation.

[0047] The outer handle mechanism 11 is a mechanical unlocking handle, which is installed in the handle installation area of ​​the vehicle door 2 and connected to the door lock, so that the door lock is driven to unlock by operating the outer handle mechanism 11, such as pulling the handle, flipping up the handle, etc.

[0048] The sensing component 12 is arranged in the external handle mechanism 11 and connected to the door lock for sensing an unlocking gesture, such as a finger reaching the sensing range of the sensing component 12 or touching the sensing component 12 , etc., and then the door lock implements the door lock unlocking operation based on the unlocking control signal sent back by the sensing component 12 .

[0049] During electric automatic unlocking, the sensing component 12 senses the unlocking gesture, and the rear door lock performs electric unlocking based on the sensed unlocking signal, and the door 2 is in a state to be opened; the operator only needs to overcome the overall resistance of various factors such as structural friction and the weight of the door 2 to open the door 2. In other words, the driving force threshold for opening the door 2 is roughly equivalent to the door opening resistance.

[0050] In the event of an electric automatic unlocking failure, such as a power failure or a functional failure of the sensing component 12, which results in the inability to implement electric automatic unlocking, the outer handle mechanism cannot be pulled and triggered by only a pulling force sufficient to overcome the door opening resistance, thereby failing to drive the door lock to unlock; the operator may naturally apply a greater pulling force until the pulling force reaches 1.3 to 1.7 times the driving force threshold for opening the vehicle door 2, that is, 1.3 to 1.7 times the door opening resistance, which will trigger the outer handle mechanism 11 and cause the outer handle mechanism 11 to operate, thereby driving the door lock to perform the unlocking operation and thereby open the vehicle door.

[0051] It is worth noting that when the electric unlocking structure based on the sensing component 12 functions normally, the external handle mechanism 11 will not be triggered when the operator pulls open the door 2, and the external handle mechanism 11 basically remains in the non-triggering position; only when the force of pulling the door 2 is greater than 1.3 to 1.7 times the driving force threshold for pulling open the door 2, the external handle mechanism 11 will be in the triggering position, that is, when the force threshold for driving the external handle mechanism 11 to achieve the unlocking action is 1.3 to 1.7 times the driving force threshold for pulling open the door 2, the external handle mechanism 11 will be triggered to drive the door lock action. In other words, in an action of pulling open the door 2, the door 2 will eventually be unlocked and pulled open, ensuring the reliability of the door opening operation, and the operation process is simple, without additional complex operations, and is easy to promote and apply.

[0052] Exemplarily, the force threshold for driving the external handle mechanism 11 to achieve the unlocking action may be 1.3 times, 1.4 times, 1.5 times, 1.6 times and 1.7 times the driving force threshold for opening the vehicle door 2, or other values ​​between 1.3 times and 1.7 times.

[0053] The vehicle door handle assembly provided by the embodiment of the present application includes an outer handle mechanism and a sensing component arranged in the outer handle area of ​​the vehicle door, and an integrated manual mechanical unlocking handle sensing automatic unlocking structure, so that when the automatic unlocking function fails, the vehicle door can be manually unlocked by operating the outer handle mechanism to ensure the reliability of the vehicle door unlocking function. On the other hand, the unlocking action threshold of the outer handle mechanism can be controlled by structural configuration settings to be significantly higher than the driving force threshold required for pulling the vehicle door, so that when the sensing unlocking function fails, the outer handle mechanism can be pulled by a large pulling force to implement mechanical unlocking, and then the vehicle door can be opened, thereby ensuring the reliability of the vehicle door unlocking and opening; when the function is normal, the unlocking gesture is sensed by the sensing component to control the door lock to automatically unlock, and when the outer handle mechanism is pulled, only a small driving force is required to overcome the overall resistance of the vehicle door opening to open the vehicle door, and the outer handle mechanism will not be triggered, thereby reducing the risk of interference between manual unlocking and automatic sensing unlocking, forming a functional integrated structure of automatic sensing unlocking and manual unlocking, so as to improve the reliability of the unlocking function. Among them, the force threshold for driving the external handle mechanism to realize the unlocking action is 1.3 to 1.7 times the driving force threshold for opening the door, so that the manual unlocking and automatic unlocking functions can be strictly distinguished, and the door can be finally opened in one door opening operation while taking into account the convenience of the unlocking operation.

[0054] Figure 2 Shows Figure 1 A top view of the inner door handle assembly in FIG. Figure 3 Shows Figure 1 A rear view of the interior door handle assembly in FIG. Figure 4 Shows Figure 3 A partial cross-sectional view of the inner door handle assembly in FIG. Figure 5 Shows Figure 4 A right side view of the inner door handle assembly in FIG. Figure 7 Shows Figure 1 An exploded view of the interior door handle assembly in FIG. Figure 8 Shows Figure 1 A rear view of the interior door handle assembly in FIG. Fig. 9 Shows Figure 8 Another angle diagram of the inner door handle assembly in FIG.

[0055] join Figures 1 to 9 In some embodiments, the external handle mechanism 11 may include a handle base 111, an external opening button 112 and an elastic limiting member 113. The handle base 111 is connected to the vehicle door 2, the external opening button 112 can be deflectably connected to the handle base 111, and the elastic limiting member 113 is connected between the external opening button 112 and the handle base 111.

[0056] The handle base 111 is the installation base of the outer handle mechanism 11 , and carries the outer opening buckle 112 , the elastic limiter 113 and the sensing component 12 ; and the handle base 111 can also be installed on the vehicle door 2 by fasteners or welding.

[0057] The outer opening handle 112 is an operable structure of the outer handle mechanism 11, which can deflect relative to the handle base 111 to generate displacement, thereby driving the door lock to unlock. It is worth noting that the displacement of the outer opening handle 112 relative to the handle base 111 can be transmitted to the door lock through a moving part such as a cable to unlock.

[0058] The elastic limiting member 113 is connected between the outer opening buckle 112 and the handle base 111, and is used to maintain the position and posture of the outer opening buckle 112; only under the action of external force, breaking through the elastic resistance of the elastic limiting member 113, can the outer opening buckle 112 be pulled to shift, or even moved to the unlocking position, triggering the outer handle mechanism 11 to achieve the unlocking operation.

[0059] Therefore, the condition for triggering unlocking of the outside opening handle 112 can be limited by limiting the elastic force applied to the outside opening handle 112 by the elastic limit member 113, that is, when the outside opening handle 112 is in the unlocking position, the force applied to the outside opening handle 112 by the elastic limit member 113 is 1.3 times to 1.7 times the driving force threshold for opening the vehicle door; when the force applied to the outside opening handle 112 by the elastic limit member 113 does not reach 1.3 times to 1.7 times the driving force threshold for opening the vehicle door, the position of the outside opening handle 112 is a non-triggering position, thereby being compatible with the requirement of opening the vehicle door 2 after electric unlocking to avoid false triggering.

[0060] Generally speaking, the elastic limiting member 112 is always in a deformed state, and always maintains elastic pressure on the outward opening buckle 112, so as to keep it in the initial shape, that is, the non-unlocking position.

[0061] In some embodiments, considering that when the outward opening button 112 is in the unlocked position, the pressure of the elastic limiter 113 is significantly higher than the door opening resistance, the reliability of the structural form and installation state of the handle base 111 can be enhanced through the structural design of the handle base 111.

[0062] Specifically, the handle base 111 may include an inner base 111a and an outer base 111b, the inner base 111a is installed in the vehicle door 2, the outer base 111b is installed on the outer door panel of the vehicle door 2, and the outer base 111b is also connected to the inner base 111a to form a stable supporting structure.

[0063] The outward opening handle 112 and the elastic limiting member 113 are respectively connected to the outer base 111b, so that when overcoming the elastic limiting member 113 to pull the outward opening handle 112, the outer base 111b needs to withstand a larger elastic pressure. The pressure is dispersed together with the inner base 111a and the outer door panel of the vehicle door 2, thereby reducing the risk of excessive deformation and damage to the outer base 111b.

[0064] That is to say, in the process of pulling the vehicle door to open, especially in the process of pulling the outer opening handle 112 to open the door, the outer base 111b serves as the main force bearing the elastic limit member 113 and external pulling force, and the pressure can be dispersed through the connection between the outer base 111b and the inner base 111a and the outer door panel of the vehicle door 2 to ensure the stability of the shape and position of the outer base 111b.

[0065] In some embodiments, in order to improve the sealing of the outer handle area, a window corresponding to the outer base 111b can be opened on the outer door panel 21 of the vehicle door 2, and the outer base 111b can be embedded in the window on the outer door panel 21, and then a seal 212 can be set between the window and the outer base 111b to seal the gap between the outer base 111b and the outer door panel 21.

[0066] In some embodiments, considering that the inner base 111a is used to strengthen the outer base 111b and share part of the pressure of the external door opening operation, the inner base 111a can be directly connected to the inside of the vehicle door 2 and connected to the outer door panel 21 or the internal structure of the vehicle door 2, so as to disperse the pressure of the external door opening operation to the entire vehicle door 2, thereby reducing the risk of deformation of the outer base 111b.

[0067] In some embodiments, a buffer member such as felt 111a2 may be provided between the inner base 111a and the outer door panel 21 to buffer the pressure applied by the inner base 111a to the outer door panel 21 and to stably connect the inner base 111a to the outer door panel 21 by utilizing its adhesive properties.

[0068] Generally speaking, the inner base 111 a can also be fixed to the structure inside the vehicle door 2 by bonding or fastener connection.

[0069] In some embodiments, in order to take into account both the smoothness of the movement of the outer handle 112 and the stability of the structure, the outer opening handle 112 can be rotatably connected to the outer base 111b through a rotating shaft connection.

[0070] Specifically, the outer handle mechanism 111 may further include a rotating shaft 114 , and the outer opening handle 112 may be rotatably connected to the outer base 111 b via the rotating shaft 114 .

[0071] In some embodiments, in order to take into account the smoothness of the movement of the elastic limit member 113 and the stability of the structure, the elastic limit member 113 may include a torsion spring 113a, and the torsion spring 113a is a spiral cylinder torsion spring. The cylinder of the torsion spring 113a is sleeved on the rotating shaft 114, and the two ends of the torsion spring 113a are respectively connected to the external opening buckle 112 and the external base 111b, so as to rely on the rotating shaft 114 to achieve limiting support to ensure the stability of its position and posture, and ensure functional stability.

[0072] Generally speaking, the number of turns of the torsion spring 113a wound by the steel wire can be designed or selected accordingly according to the actual opening resistance of the vehicle door 2.

[0073] In some embodiments, the torsion spring 113a can be set as a bidirectional torsion spring, that is, one winding end of the torsion spring 113a is set in the middle of the torsion spring 113a, and the winding segment on the other side is located at both ends of the torsion spring 113a, and the untwisting trend of the first winding end 113a1 located in the middle is opposite to the untwisting trend of the second winding end 113a2 at both ends of the torsion spring 113a, and the untwisting trends of the second winding ends 113a2 located at both ends of the torsion spring 113a are the same; thereby ensuring the uniformity of the force on the outward-opening buckle 112 and the torsion spring 113a, and the stability of the posture.

[0074] The first winding end 113a1 is connected to the outer opening buckle 112, and the second winding end 113a2 is connected to the outer base 111b.

[0075] In some embodiments, in order to limit the axial movement of the torsion spring 113a, a limiting column 112a may be provided on the outward opening buckle 112, and the first winding end 113a1 in the middle of the torsion spring 113a is sleeved on the limiting column 112a.

[0076] In some embodiments, in order to facilitate the installation of the torsion spring 113a and reduce the risk of interference with surrounding structures, a first ear 111b1 can be provided on the outer base 111b, and a second ear 112b can be provided on the external opening handle 112. The rotating shaft 114 is respectively provided in the first ear 111b1 and the second ear 112b, so that a certain gap is left between the rotating shaft 114 and the external opening handle 112 and the outer base 111b to accommodate the torsion spring 113a and leave sufficient deformation space.

[0077] Generally speaking, through holes are provided in the first ear 111b1 and the ear 112b for accommodating the rotating shaft 114 to ensure the smooth rotation of the outward-opening buckle handle 112 .

[0078] The first ear 111b1 and the second ear 112b can also be divided into two parts and connected to the two ends of the rotating shaft 114 respectively. The torsion spring 113a can be located between the two first ears 111b1 and the two second ears 112b to ensure the uniformity of the force on the outer opening handle 112, the rotating shaft 114 and the outer base 111b, and to limit the axial movement of the torsion spring 113a.

[0079] In some embodiments, a stop structure 111 a 1 may be further provided on the inner base 111 a , located at both ends of the rotating shaft 114 , to limit the axial movement of the rotating shaft 114 .

[0080] The stop structure 111a1 can also be used to cover both ends of the rotating shaft 114 through a morphological setting to achieve end protection, prevent water stains, dust, etc. from entering, and avoid rust.

[0081] In some embodiments, the outward opening handle 112 can be set as a hollow part, and the sensing component 12 can be set inside the outward opening handle 112, so that the unlocking gesture can be sensed and acquired when holding the outward opening handle 112, thereby further optimizing the convenience and comfort of operation.

[0082] In some embodiments, the sensing component 12 may include a fingerprint recognition sensor or the like, which is a sensor device capable of identifying biometric information.

[0083] In some embodiments, the outward opening handle 112 can be configured as a fastening piece between the bottom shell 112c and the upper cover 112d, and the interior thereof serves as a cavity for accommodating the sensing component 12, thereby simplifying the installation of the sensing component 12.

[0084] Generally speaking, a sensing window 112d1 may be opened on the upper cover 112d to expose the sensing end of the sensing component 12.

[0085] In some embodiments, a door lock device is also provided, including the above-mentioned external handle assembly 1 and a door lock, wherein the external opening button 112 in the external handle assembly 1 and the sensing component 12 are respectively connected to the door lock to realize manual mechanical unlocking and induction unlocking.

[0086] Generally speaking, the sensing component 12 can be connected to an unlocking controller via a signal cable. The unlocking controller is equipped with an unlocking drive mechanism, which is connected to the lock core of the door lock. When an unlocking gesture is sensed, the unlocking controller controls the unlocking drive mechanism to pull the lock core, causing the lock core to shift to achieve unlocking.

[0087] The unlocking drive mechanism can adopt action actuators such as motors and electric cylinders.

[0088] The outer opening handle 112 can be connected to the door lock through a connecting piece such as a cable 115, so that the displacement of the outer opening handle 112 is directly transmitted to the door lock, thereby mechanically pulling the lock core to shift and completing unlocking.

[0089] In some embodiments, a car is also provided, including the above-mentioned door lock device, which can be installed on the car door 2. The car body is provided with a card slot, a card ring and other structures that cooperate with the lock core, which are used to cooperate with the lock core to lock the car door 2.
