A smart interior door handle assembly for a vehicle

Abstract

This invention provides an intelligent inward-opening door handle assembly for vehicles, comprising: a housing, an inward-opening handle, a metal shaft, an inward-opening cable, a main elastic element, a micro switch, and a threshold spring. The inward-opening handle includes a handle portion and a connecting portion, the bottom of which is provided with a wedge-shaped ramp. When the inward-opening handle rotates, the contact moves towards the apex of the wedge-shaped ramp. When the contact is fully released to the apex of the wedge-shaped ramp, a first electrical signal is released to the door control system to electrically unlock the door lock. When the inward-opening handle resets, the contact moves towards the bottom of the wedge-shaped ramp. When the contact is fully compressed to the bottom of the wedge-shaped ramp, a second electrical signal is released to the door control system to electrically lock the door lock. The threshold spring abuts against the bottom of the connecting portion during mechanical unlocking to provide force feedback. The addition of the threshold spring allows the user to feel a certain resistance within a certain rotation angle range of the inward-opening handle, enabling the user to distinguish between mechanical and electric unlocking through force feedback.

Description

Technical Field

[0001] This invention relates to the field of interior door handles for automobiles, and more specifically to an intelligent interior door handle assembly for a vehicle. Background Technology

[0002] Traditional car interior door handle assembly, such as Figure 1 As shown, by operating the inner handle to rotate, the inner structure of the handle and the pull cable tongue engage, causing an arc-shaped movement, which displaces the pull cable tongue. When the displacement reaches a certain stroke inside the door lock, the door lock mechanically unlocks.

[0003] Traditional car interior door handle assemblies have incorporated electric unlocking functionality in response to the trend of electrification. The main way to achieve this is by adding an electric unlocking structure to the door lock design, and its travel is usually shorter than that of mechanical unlocking.

[0004] However, this approach has the following four drawbacks:

[0005] 1. High cost; the door lock assembly resembles a large black box, such as... Figure 2 As shown, it has a high degree of integration and a complex internal structure.

[0006] 2. Difficult to repair: If any part in the door lock assembly malfunctions, it is difficult to disassemble and repair the entire black box.

[0007] 3. The unlocking mechanism in the door lock assembly requires a relatively large travel and tolerance. The travel of electric unlocking is typically 7±2.5mm, which translates to a rotation angle of approximately 20° for the inward-opening handle. In contrast, the travel of mechanical lock unlocking is typically around 12±1.5mm, which translates to a rotation angle of approximately 30° for the inward-opening handle. Users cannot clearly distinguish the opening angle range between electric and mechanical locks, thus reducing the technological feel, perceived value, and operational comfort of the configuration.

[0008] 4. Users have low differentiation between electric and mechanical unlocking modes, and because the opening angles are similar and not fixed, users easily mix up the two modes. Typically, electric unlocking only requires one click to unlock the door, while mechanical unlocking requires first unlocking the safety mechanism, which easily leads to customer complaints. Furthermore, in child lock mode and other possible situations, if a user pulls the inward handle to its maximum angle, the door lock may enter emergency mode or other malfunctions. Therefore, this solution leads to an increased failure rate. Summary of the Invention

[0009] To address the aforementioned issues, this invention proposes an intelligent inward-opening handle assembly for vehicles. This assembly can trigger electric unlocking at a small angle, allowing users to more easily achieve electric unlocking via the inward-opening handle, adding intelligence to the electrification process. Furthermore, this invention provides an inward-opening handle assembly that uses force feedback to differentiate between mechanical and electric unlocking, enhancing the user's perception of the unlocking mode and significantly improving the technological feel, perceived value, and operational comfort of the configuration.

[0010] This invention proposes an intelligent inward-opening handle assembly for a vehicle, comprising:

[0011] case;

[0012] An inward-opening handle includes a hand-holding portion and a connecting portion. The connecting portion is located on one side of the hand-holding portion and passes through the housing from the first side of the housing. The connecting portion has a through hole running vertically through the housing, and a wedge-shaped ramp is provided at the bottom of the connecting portion.

[0013] A metal shaft is located on the second side of the housing, and the metal shaft is rotatably connected to the inner handle through a through hole in the connecting part;

[0014] The inner opening cable has a first end connected to the door lock and a second end provided with a latch. The latch abuts against the connection part of the inner opening handle. Rotating the inner opening handle causes the latch to move. When the rotation angle of the inner opening handle is within the first angle range, the door lock is mechanically unlocked.

[0015] The main elastic element is sleeved on the metal shaft, with its first end abutting against the housing and its second end abutting against the inner handle.

[0016] A micro switch is installed on the second side of the housing. The micro switch has a tail wire socket at its tail end, which is connected to the door control system. The contact at the top of the micro switch abuts against the bottom of the wedge-shaped ramp. When the inner handle is rotated, the contact moves to the top of the wedge-shaped ramp. When the contact is fully released to the top of the wedge-shaped ramp, a first electrical signal is released to the door control system to electrically unlock the door lock. When the inner handle is reset, the contact moves to the bottom of the wedge-shaped ramp. When the contact is fully compressed to the bottom of the wedge-shaped ramp, a second electrical signal is released to the door control system to electrically lock the door lock.

[0017] A threshold spring, which abuts against the bottom of the connecting part to provide force feedback when the rotation angle of the inner handle is within the second angle range.

[0018] In one embodiment, the bottom of the connecting part of the inward-opening handle is provided with a first groove and a second groove that match the height of the threshold spring when it is not deformed.

[0019] When the rotation angle of the inward-opening handle is the first angle, the threshold spring is located in the first groove;

[0020] When the rotation angle of the inward-opening handle is the second angle, the top of the threshold spring abuts against the bottom of the connecting part, the threshold spring is compressed and deformed, and provides force feedback to the inward-opening handle;

[0021] When the rotation angle of the inward-opening handle is the third angle, the threshold spring is located in the second groove;

[0022] The second angle is located within the second angle range. The second angle is greater than the rotation angle of the inner opening handle when the contact is fully released to the top of the wedge slope, and the second angle is less than the minimum angle within the first angle range.

[0023] In one embodiment, the first angle is less than 8°, the second angle is greater than or equal to 8° and less than or equal to 15°, and the third angle is greater than 15°.

[0024] In one embodiment, the vehicle's intelligent inward-opening handle assembly further includes a latch cover, which is mounted on the second side of the housing. The latch cover is provided with guide rails that match the upper and lower ends of the latch, and the latch moves along the guide rails.

[0025] In one embodiment, the vehicle's intelligent inward-opening handle assembly further includes a reinforcing spring sleeved on a metal shaft, abutting a first end of the reinforcing spring against the housing, and a second end of the reinforcing spring abutting atop the connecting portion when the inward-opening handle is rotated.

[0026] In one embodiment, a first groove is formed at the top of the connecting portion;

[0027] When the rotation angle of the inward-opening handle is less than or equal to the fourth angle, the second end of the reinforcing spring is located in the first groove;

[0028] When the rotation angle of the inward-opening handle is greater than the fourth angle, the second end of the reinforcing spring abuts against the inner wall of the first groove, and the reinforcing spring is compressed and deformed, providing force feedback to the inward-opening handle.

[0029] In one embodiment, the fourth angle is 15°.

[0030] In one embodiment, the rotation angle within the first angle range is greater than or equal to 30° and less than or equal to 35°.

[0031] In one embodiment, when the rotation angle of the inward-opening handle is the sixth angle, a first electrical signal is released to the door control system to electrically unlock the door lock when the contact is fully released to the top of the wedge ramp.

[0032] The process of resetting the inner handle is the process of returning the rotation angle of the inner handle to 0°.

[0033] In one embodiment, the sixth angle is 5°.

[0034] The intelligent inward-opening handle assembly for vehicles of the present invention has the following beneficial effects:

[0035] 1. This invention introduces a microswitch into the inward-opening handle assembly. A wedge-shaped ramp causes the microswitch's contacts to displace, sending an electrical signal to the door control system. The door control system then outputs a command to unlock the door, achieving an electric unlocking function. The contact trigger displacement is extremely small, translating to a handle rotation angle of only about 5°, allowing the user to unlock the door with a slight flick of the handle.

[0036] 2. This invention introduces a threshold spring into the inward-opening handle assembly. When the rotation angle of the inward-opening handle is 8-15°, the threshold spring generates force feedback on the inward-opening handle, so that the user feels a certain resistance within this rotation angle range of the handle, reminding the customer that the mechanical unlocking stroke will be entered later, thereby distinguishing between mechanical unlocking and electric unlocking.

[0037] 3. This invention adds a coaxial reinforcing spring. When the rotation angle is greater than 15° to the maximum design angle of 55°, the rotational operating force of the inward opening handle is increased, so that the user will not easily and quickly pull the handle to the maximum angle, reducing the possibility of the door lock entering the emergency mode and reducing the failure rate.

[0038] 4. The inward-opening handle assembly of this invention has an open structure, eliminating the need for complete disassembly to address individual component failures, thus improving maintenance feasibility. The inward-opening handle assembly of this invention has low overall cost and requires minimal space. Compared to traditional inward-opening handle assemblies, it does not increase the overall structural design space. Attached Figure Description

[0059] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0060] like Figure 3a and Figure 3bAs shown, this invention proposes an intelligent inward-opening handle assembly for vehicles. Specifically, it is an electromechanical dual-unlocking inward-opening handle assembly with threshold reminder, comprising: a housing 1, an inward-opening handle 2, a metal shaft 3, an inward-opening cable 11, a main elastic element, a micro switch 8, and a threshold spring 9. The inward-opening handle 2 includes a handgrip and a connecting portion. The connecting portion is located on one side of the handgrip and passes through the housing 1 from the first side. The connecting portion has a through hole extending vertically, and a wedge-shaped ramp is provided at the bottom. The metal shaft 3 is located on the second side of the housing 1 and is rotatably connected to the inward-opening handle 2 through the through hole in the connecting portion. The first end of the inward-opening cable 11 is connected to the door lock, and the second end of the cable has a latch. The latch abuts against the connecting portion of the inward-opening handle 2. Rotation of the inward-opening handle 2 causes the latch to move. When the rotation angle of the inward-opening handle 2 is within a first angle range, the door lock is mechanically unlocked. The main elastic element is sleeved on the metal shaft 3. The first end of the main elastic element abuts against the housing 1, and the second end of the main elastic element abuts against the inner opening handle 2. In this embodiment, the main elastic element is preferably the main spring 5. A micro switch 8 is installed on the second side of the housing 1. The tail of the micro switch 8 has a tail wire socket, which is connected to the door control system. The contact at the top of the micro switch 8 abuts against the bottom of the wedge-shaped ramp. When the inner opening handle 2 is rotated, the contact moves towards the top of the wedge-shaped ramp. When the contact is fully released to the top of the wedge-shaped ramp, a first electrical signal is released to the door control system to electrically unlock the door lock. When the inner opening handle 2 is reset, the contact moves towards the bottom of the wedge-shaped ramp. When the contact is fully compressed to the bottom of the wedge-shaped ramp, a second electrical signal is released to the door control system to electrically lock the door lock. The threshold spring 9 abuts against the bottom of the connecting part when the rotation angle of the inner opening handle 2 is within the second angle range to provide force feedback. The threshold spring 9 is located at the bottom of the connecting part of the inner opening handle 2.

[0061] Furthermore, such as Figure 6a , Figure 6b , Figure 6c , Figure 6d and Figure 6eAs shown, the bottom of the connecting part of the inner opening handle 2 is provided with a first groove and a second groove that match the height of the threshold spring 9 when it is not deformed. When the rotation angle of the inner opening handle 2 is the first angle, the threshold spring 9 is located in the first groove. At this time, the threshold spring 9 has no motion interference with the inner opening handle 2, no deformation, and no force feedback. When the rotation angle gradually increases to the second angle, the threshold spring 9 gradually moves away from the first groove, and the top of the threshold spring 9 abuts against the bottom of the connecting part. The threshold spring 9 is compressed and deformed, providing force feedback to the inner opening handle 2. When the rotation angle continues to increase to the third angle, the threshold spring 9 disengages from the bottom of the connecting part until it enters the second groove, and the threshold spring 9 returns to its state of no force, no deformation, and no force feedback. The addition of the threshold spring 9 allows the user to feel a certain resistance within a certain rotation angle range of the inner opening handle 2, reminding the user that the mechanical unlocking stroke is about to begin. The user can distinguish between mechanical unlocking and electric unlocking through force feedback. The second angle is located within the second angle range. The second angle is greater than the rotation angle of the inner opening handle when the contact is fully released to the top of the wedge slope, and the second angle is less than the minimum angle within the first angle range.

[0062] In this preferred embodiment, the first angle is less than 8°, the second angle is greater than or equal to 8° and less than or equal to 15°, and the third angle is greater than 15°. Specifically, as shown... Figure 6b As shown, when the rotation angle of the inner handle 2 is less than 8°, the threshold spring 9 has no motion interference with the inner handle 2, and therefore no deformation or force feedback. Figure 6b As shown, when the rotation angle gradually increases to 8°, the threshold spring 9 gradually contacts the bottom of the connecting part of the inner handle 2, and the pressure deformation generates force feedback. Figure 6c As shown, when the rotation angle is between 10-12°, the threshold spring 9 is under continuous pressure, mainly providing frictional force feedback. Figure 6d As shown, when the rotation angle is greater than 15°, the threshold spring 9 disengages from the inner handle 2, returning to a state of no force, no deformation, and no feedback. In one embodiment, the threshold spring 9 is fixed to the housing 1 by the threshold spring fixing bolt 7, see [link to relevant documentation]. Figure 8b .

[0063] Furthermore, such as Figure 8a As shown, the intelligent inward-opening handle assembly of a vehicle according to an embodiment of the present invention also includes a tongue cover 10. The tongue cover 10 is installed on the second side of the housing 1. The tongue cover 10 is provided with guide rails that match the upper and lower ends of the tongue, and the tongue moves along the guide rails.

[0064] Furthermore, such as Figure 7aAs shown, the intelligent inward-opening handle assembly of a vehicle according to an embodiment of the present invention further includes a reinforcing spring 4, which is sleeved on the metal shaft 3. The first end of the reinforcing spring 4 abuts against the housing 1, and the second end of the reinforcing spring 4 abuts against the top of the connecting part when the inward-opening handle 2 is rotated.

[0065] Furthermore, such as Figure 7b and Figure 7c As shown, a first groove is formed at the top of the connecting part. When the rotation angle of the inner opening handle 2 is less than or equal to the fourth angle, the second end of the reinforcing spring 4 is located in the first groove. When the rotation angle of the inner opening handle 2 is greater than the fourth angle, the second end of the reinforcing spring 4 abuts against the inner wall of the first groove, and the reinforcing spring is compressed and deformed, providing force feedback to the inner opening handle.

[0066] In this preferred embodiment, the fourth angle is 15°. Specifically, as shown... Figure 7b As shown, when the rotation angle of the inward-opening handle is less than or equal to 15°, the reinforcing spring 4 is in its free travel, without any force or feedback. When the rotation angle is greater than 15°, the reinforcing spring 4 begins to contact the inner wall of the first groove on the inward-opening handle, receiving force and generating force feedback. By adding a coaxial reinforcing spring, when the rotation angle is designed to be greater than 15° up to the maximum design angle of 55°, the operating force for rotating the handle is increased, preventing the user from easily and quickly pulling the handle to the maximum angle, reducing the possibility of the door lock entering emergency mode, and lowering the failure rate.

[0067] Furthermore, when the rotation angle of the inward-opening handle reaches the fifth angle, the door lock is mechanically unlocked. Preferably, in this embodiment, the rotation angle within the first angle range is greater than or equal to 30° and less than or equal to 35°. Specifically, the inward-opening handle 2 rotates along the metal shaft 3 under external operating force, causing the latch of the inward-opening cable to rotate synchronously. Simultaneously, the main spring 5 deforms, generating a rebound force. Mechanical unlocking is achieved when the rotation angle is approximately 30° to 35°. See [link to relevant documentation]. Figure 4a .

[0068] In one specific embodiment, a second groove is formed below the connecting portion, and the second end of the main spring 5 is located in the second groove. See [reference needed]. Figure 4b When the inner handle 2 is rotated, the main spring 5 abuts against the inner wall of the second groove, and the main spring 5 rotates with the inner handle 2 and deforms.

[0069] Furthermore, when the rotation angle of the inward-opening handle 2 reaches the sixth angle, the first electrical signal is released to the door control system when the contact is fully released to the top of the wedge-shaped ramp to electrically unlock the door lock. The process of resetting the inward-opening handle 2 to 0° rotation angle is then described.

[0070] In this preferred embodiment, the sixth angle is 5°. Specifically, the wedge-shaped ramp and the contact of the micro switch 8 generate relative movement, see [link to relevant documentation]. Figure 5aWhen the inward-opening handle 2 rotates to approximately 5°, the contact point releases to the top of the wedge-shaped ramp, releasing the first electrical signal to the door control system to electrically unlock the door lock. See [link / reference]. Figure 5b When the inward-opening handle 2 returns to its initial position of 0°, the contact is compressed to the bottom of the wedge-shaped ramp, releasing a second electrical signal to the door control system to electrically lock the door. See [link / reference]. Figure 5c Because the contact trigger displacement is extremely small, which translates to a handle rotation angle of only about 5°, users can unlock the car door with just a slight flick of the handle.

[0071] It should be understood that the angle of the wedge-shaped ramp matching structure in this invention, as well as the angle settings of each interval, are adjustable.

[0072] In one specific embodiment, the micro switch 8 is snapped and fixed to the housing 1, see [reference]. Figure 8b .

[0073] In one specific embodiment, limiting members are used to limit the reinforcing spring and the main spring, respectively. See [reference needed]. Figure 8b .

[0074] In one specific embodiment, a handle rebound buffer pad 6 is also provided on the connecting part, which plays a buffering role when the inward opening handle 2 rebounds.

[0075] The intelligent inward-opening handle assembly of this invention, through multi-range control of the rotation angle and force feedback of the inward-opening handle, can potentially influence users to develop good usage habits, increase comfort and a sense of technology, and enhance product value. For a comparison of the operating force of the intelligent inward-opening handle assembly of this invention with that of traditional electric or mechanical unlocking control methods, please refer to [link to relevant documentation]. Figure 9 The user can trigger the electric unlocking by slightly flicking the handle, and the force feedback will remind the user to distinguish the method before entering the mechanical unlocking.

[0076] It should be understood that the fixing methods in this invention are not limited to bolts, snap-fitting, riveting, welding, etc. The springs and spring sheets in this invention are not limited to any particular shape; various spring structures can be substituted. Furthermore, this invention is not limited to a single-axis structure.

[0077] The intelligent inward-opening handle assembly for vehicles of the present invention has the following beneficial effects:

[0078] 1. This invention introduces a microswitch into the inward-opening handle assembly. A wedge-shaped ramp causes the microswitch's contacts to displace, sending an electrical signal to the door control system. The door control system then outputs a command to unlock the door, achieving an electric unlocking function. The contact trigger displacement is extremely small, translating to a handle rotation angle of only about 5°, allowing the user to unlock the door with a slight flick of the handle.

[0079] 2. This invention introduces a threshold spring into the inward-opening handle assembly. When the rotation angle of the inward-opening handle is 8-15°, the threshold spring generates force feedback on the inward-opening handle, so that the user feels a certain resistance within this rotation angle range of the handle, reminding the customer that the mechanical unlocking stroke will be entered later, thereby distinguishing between mechanical unlocking and electric unlocking.

[0080] 3. This invention adds a coaxial reinforcing spring. When the rotation angle is greater than 15° to the maximum design angle of 55°, the rotational operating force of the inward opening handle is increased, so that the user will not easily and quickly pull the handle to the maximum angle, reducing the possibility of the door lock entering the emergency mode and reducing the failure rate.

[0081] 4. The inward-opening handle assembly of this invention has an open structure, eliminating the need for complete disassembly to address individual component failures, thus improving maintenance feasibility. The inward-opening handle assembly of this invention has low overall cost and requires minimal space. Compared to traditional inward-opening handle assemblies, it does not increase the overall structural design space.

[0082] It should be noted that, unless otherwise explicitly specified and limited, terms such as "set," "connect," and "install" used in the description of this application should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal connection of two components. Those skilled in the art can understand its specific meaning in this application according to the specific circumstances. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0083] The embodiments described above are merely further illustrations of the present invention and are not intended to limit the present invention in any other way. The present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding modifications and changes based on the present invention, but all such modifications and changes should fall within the protection scope of the present invention.
