Description

Technical Field

[0001] This invention relates to the field of smart door handle technology, and particularly to automotive door handle assemblies. Background Technology

[0002] As a core component of intelligent vehicle entry systems, the integration and multi-functional design of automotive door handle assemblies have become an industry trend. Modern vehicle door handle systems need to simultaneously achieve multiple operating modes, including electric unlocking / locking, external mechanical emergency opening, and internal manual control, involving the coordinated integration of motor drive, mechanical transmission, and emergency operation mechanisms. Existing technologies typically employ multiple independent transmission mechanisms to achieve different functions, such as using an independent motor to drive the lock body, an external mechanical cable for emergency unlocking, and separate internal and external opening / removing mechanisms. Such designs require the installation of complex components such as motors, lock bodies, gear sets, actuating plates, and linkages within the limited space of a vehicle door handle, posing challenges to space utilization and structural compactness.

[0003] Existing door handle assemblies have significant drawbacks in achieving multi-functional integration: 1. The structure is redundant and complex, making it unsuitable for installation on thin doors. 2. Electric drive, manual emergency operation, and inward / outward opening require independent transmission chains, resulting in low operational reliability. For example, the mechanical coupling between the manual and electric systems is insufficient, and traditional gear sets lack precise angle control for half-lock / full-lock states, easily leading to malfunctions; the entire assembly needs to be disassembled when an independent mechanism fails. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automotive door handle assembly. The assembly includes a housing and a switch assembly disposed within the housing. The switch assembly includes an outer opening pull plate, an inner opening pull plate, a manual unlocking cylinder, and a lock body disposed within the bottom cavity of the housing. The housing contains a drive shaft and a motor. An eccentric mechanism is provided between the drive shaft and the outer opening pull plate. The other end of the outer opening pull plate is controlled and connected to the lock body. A drive plate is rotatably mounted within the housing, and the inner opening pull plate is driven by the drive plate. The power output shaft of the motor is transmitted to the drive shaft via a gear structure to automatically rotate the drive shaft. The switch assembly also includes a linkage mechanism disposed within the housing. One end of the linkage mechanism is driven and connected to the gear structure, and then driven and connected to the drive shaft by the gear structure. The other end of the linkage mechanism is connected to the manual unlocking cylinder for manually rotating the drive shaft.

[0005] As a further preferred embodiment, the gear structure includes a first full gear mounted on the motor power output shaft and a driven half gear mounted on the top of the drive shaft, wherein the first full gear meshes with the driven half gear.

[0006] As a further preferred embodiment, the side of the housing is provided with a lock hole, the linkage mechanism includes a connecting seat that is rotatably connected in the lock hole, a manual lock cylinder is connected to the connecting seat, a manual pull arm is installed on the connecting seat, a drive half gear is installed at the other end of the manual pull arm, a drive shaft is installed inside the housing, and a gear is installed at the top of the drive shaft, the gear meshes with the drive half gear, and the bottom end of the drive shaft is driven to connect to the lock body.

[0007] As a further preferred embodiment, the outward-opening pull plate is rotated to the inner side of the outer casing. The outer casing has a pre-reserved outer slot. A slide is installed inside the outer casing, and the slide has a slide rail. The eccentric mechanism includes a wheel on the drive shaft, an eccentric seat mounted on the wheel, and a slide arm that engages with the slide rail on the slide. The outward-opening pull plate has three claws. The first claw extends into the outer slot, the second claw extends into the sliding path of the slide arm and has a lever-shaped opening part, and the third claw has a hook part and is connected to the outer casing through a first torsion spring, so that the rotation angle position of the outward-opening pull plate is self-locked. The other end of the slide arm away from the second claw enters the bottom end of the wheel and is movably connected to the eccentric seat.

[0008] As a further preferred embodiment, the inner opening actuating plate is rotated on the outer shell, the outer shell has an inner groove on one end, one end of the inner opening actuating plate extends into the inner groove, the other end extends into one end of the drive plate and is provided with an arc-shaped triggering part that triggers the connection between the two ends, and the other end of the drive plate is connected to the lock body.

[0009] As a further preferred embodiment, a second torsion spring is provided between the drive plate and the junction of the drive plate and the housing to enable the drive plate to automatically reset.

[0010] As a further preferred embodiment, the housing is further provided with a circuit board, on which a control module is provided. The control module is electrically connected to the motor. The control module includes a first attitude sensor disposed relative to the outer opening pull plate and the inner opening pull plate, a second attitude sensor disposed relative to the manual unlocking cylinder, and a signal interface for receiving environmental feedback signals.

[0011] As a further preferred embodiment, the control module is configured with a configuration strategy and a control strategy, the configuration strategy including: Step S1: Obtain the current state until the preset standard conditions are met, then proceed to step S2; Step S2: Obtain the state information of the first attitude sensor until the corresponding configured action is matched in the action matching library; Step S3: Configure the priority label of the corresponding configuration action according to the state information of the second attitude sensor; Step S4: Configure the actions and corresponding priority tags in the motor execution information library; Step S5: Return to step S1; The control strategy includes: Step A1: Obtain the current state information of the first attitude sensor to match the corresponding priority tag from the motor execution library; Step A2: Obtain the current environmental feedback signal to generate a state execution instruction based on the priority label. The controller controls the motor to work in the target state according to the state execution instruction.

[0012] As a further preferred embodiment, the standard conditions include attitude standard conditions and control standard conditions. The attitude standard conditions are configured to acquire the state information of the first attitude sensor and the state information of the second attitude sensor until a preset attitude information benchmark is met. The control standard conditions are configured to acquire the corresponding configuration permission instruction from the signal interface.

[0013] The advantages of this invention compared to the prior art are: 1. Highly integrated structural design, breaking through space limitations: Through an original dual-drive shaft (A / B shaft) + eccentric mechanism + half-gear transmission topology, the four functional modules of electric drive, external opening, internal opening, and manual unlocking cylinder are integrated into a single compact housing, saving space. The meshing design of the driven half-gear and the first full gear reduces space occupation compared to traditional full gear sets. The lock body is located in the bottom chamber of the outer shell, and the gear structure and linkage mechanism are arranged in layers in the vertical direction to achieve efficient use of three-dimensional space. The overall volume is smaller than that of traditional solutions, making it a perfect fit for ultra-thin car doors.

[0014] 2. An innovative failure degradation path is established, from electric to manual to mechanical emergency response, ensuring unlocking under any operating condition. Electric unlocking is prioritized: the motor drives the driven half-gear via the first full gear, which in turn rotates the drive shaft. The drive shaft then drives the precise transmission chain of the eccentric mechanism, enabling ±45° (half-lock) and ±90° (full-lock) angle control of the lock body. When the electric unlock fails, the manual unlocking cylinder drives the B drive shaft via the active half-gear of the linkage mechanism. The B drive shaft unlocks with a single-stage transmission, improving transmission efficiency and reducing the need for disassembly and repair in case of independent unit failure.

[0017] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] In one implementation, such as Figures 1-6 As shown: This embodiment provides an automotive door handle assembly, including a housing 1 and a switch assembly 2 disposed within the housing 1. The switch assembly 2 includes an outward-opening pull plate 21, an inward-opening pull plate 22, a manual unlocking cylinder 23, and a lock body 7 disposed within the bottom cavity of the housing 1. The housing 1 contains an A drive shaft 3A and a motor 4. An eccentric mechanism 31 is provided between the A drive shaft 3A and the outward-opening pull plate 21. The other end of the outward-opening pull plate 21 is controlled and connected to the lock body 7. A drive plate is rotated within the housing 1, and the inward-opening pull plate 22 is driven by the drive plate. The power output shaft of the motor 4 is connected to the A drive shaft 3A. The drive shafts 3A are driven by a gear structure to drive the A drive shaft 3A to rotate automatically. The switch assembly 2 also includes a linkage mechanism 24 disposed in the housing 1. One end of the linkage mechanism 24 is driven to the gear structure and is driven to the A drive shaft 3A by the gear structure. The other end of the linkage mechanism 24 is connected to the manual unlocking core 23 for manually rotating the A drive shaft 3A. The gear structure includes a first full gear 41 mounted on the power output shaft of the motor 4 and a driven half gear 42 mounted on the top of the A drive shaft 3A. The first full gear 41 meshes with the driven half gear 42.

[0019] The outer casing 1 has a lock hole 105 on its side. The linkage mechanism 24 includes a connecting seat 241 that is connected to the lock hole 105. The manual lock cylinder 23 is connected to the connecting seat 241. A manual pull arm 242 is installed on the connecting seat 241. A drive half gear 243 is installed at the other end of the manual pull arm 242. A B drive shaft 3B is installed inside the outer casing 1. A gear is installed at the top of the B drive shaft 3B. The gear meshes with the drive half gear 243. The bottom end of the B drive shaft 3B drives the lock body 7.

[0020] Electric working principle: When the motor 4 is energized, it drives the first full gear 41 to rotate. The first full gear 41 meshes with the driven half gear 42 to rotate. The driven half gear 42 drives the A drive shaft 3A to rotate. The A drive shaft 3A drives the eccentric mechanism 31 to rotate counterclockwise. The eccentric mechanism 31 drives the outward opening plate 21. The inner end of the outward opening plate 21 drives the moving part of the lock body 7 to complete the opening and closing action (locking and unlocking) relative to the fixed part of the lock body 7. The forward and reverse rotation of the motor 4 realizes the control of the lock body 7 to complete the locking and unlocking through the above series of transmission relationships. The angle of the forward and reverse rotation of the motor 4 also realizes the control of the degree of locking of the lock body 7 through the above series of transmission relationships. For example, when the motor rotates at ±45 degrees, the lock body is controlled to complete half-locking or half-opening through the above series of transmission relationships. For example, when the motor rotates at ±90 degrees, the lock body is controlled to complete fully open or fully locked through the above series of transmission relationships.

[0021] External pulling principle: When the lock body 7 is adjusted to half lock or full lock by the above electric method, the external opening pulling plate 21 is manually operated to rotate the external opening pulling plate 21 inward. At the same time as the external opening pulling plate 21 rotates, one end of it makes squeezing contact with the moving part of the lock body 7, forcing the moving part of the lock body to complete the unlocking.

[0022] Internal pulling principle: Driven by the above-mentioned electric working principle, when the moving part of the lock body is finally adjusted to half lock or full lock relative to the fixed part, the internal opening pulling plate 22 is manually operated to rotate downward. Using the external opening pulling plate 21 and the trigger drive plate, the drive plate drives the A drive shaft 3A to rotate. The A drive shaft 3A drives the eccentric mechanism 3 to rotate clockwise. The eccentric mechanism 31 drives the external opening pulling plate 21. The inner end of the external opening pulling plate 21 drives the moving part of the lock body 7 to unlock relative to the fixed part of the lock body 7.

[0023] Operating principle of manual unlocking cylinder 23: When the moving part of the lock body 7 is adjusted to the half-lock or full-lock position relative to the fixed part of the lock body under the electric working principle described above, the manual unlocking cylinder 23 in the lock hole 105 is rotated clockwise. The inner end of the manual unlocking cylinder 23 drives the manual pull arm 242 of the linkage mechanism 24 to move linearly. The active half gear 243 at the inner end of the manual pull arm 242 meshes with the gear and rotates. The gear drives the B drive shaft 3B to rotate. The bottom end of the B drive shaft 3B drives the moving part of the lock body 7 to complete the unlocking.

[0024] By employing a unique dual-drive shaft (A / B shaft) + eccentric mechanism + gear transmission topology, the four functional modules of electric drive, outward opening, inward opening, and manual unlocking cylinder 23 are integrated into a single compact housing 1. This highly integrated structural design overcomes space limitations: the unique dual-drive shaft (A / B shaft) + eccentric mechanism + half-gear transmission topology integrates the four functional modules of electric drive, outward opening, inward opening, and manual unlocking cylinder 23 into a single compact housing 1, saving space. The meshing design of the driven half-gear 42 and the first full gear 41 reduces space occupation compared to traditional full gear sets; the lock body 7 is placed in the bottom cavity of the housing 1, and the gear structure and linkage mechanism 24 are arranged in layers in the vertical direction, achieving efficient utilization of three-dimensional space. The overall volume is smaller than traditional solutions, perfectly adapting to ultra-thin car doors. Furthermore, an innovative failure degradation path is established, transitioning from electric to manual to mechanical emergency response, ensuring unlocking under any operating condition. Electric unlocking takes priority: motor 4 drives the driven half-gear via the first full gear transmission. The driven half-gear rotates the drive shaft, which in turn drives the precise transmission chain of the eccentric mechanism, enabling ±45° (half-lock) and ±90° (full-lock) angle control of the lock body. When electric unlocking fails, the manual unlocking cylinder 23 drives the B drive shaft via the active half-gear of the linkage mechanism. The B drive shaft unlocks with a single-stage transmission, improving transmission efficiency. Moreover, the multi-position unlocking mode allows other positions to remain operational even when one position fails, reducing the need for disassembly and maintenance, extending service life, and enabling multi-position unlocking in case of accidental locking, ensuring high security.

[0025] In another embodiment, the outward-opening pull plate 21 is connected to the inside of the outer casing 1 near the outside. The outer casing 1 has a pre-reserved outer slot 101 for easy manual operation of the outward-opening pull plate 21. A slide 102 is installed inside the outer casing 1, and the slide 102 is provided with a slide rail. The eccentric mechanism 31 includes a wheel 311 mounted on the drive shaft A 3A, an eccentric seat 312 mounted on the wheel 311, and a slide arm 313 that cooperates with the slide 102 through the slide rail. The outward-opening pull plate 21 is provided with three corner claws. 211, its first claw 211 extends into the outer groove 101, its second claw 211 extends into the sliding path of the sliding arm 313 and is provided with a lever-shaped opening part 212, its third claw 211 is provided with a hook part 213 and is connected to the outer casing 1 through a first torsion spring 214, so that the rotation angle position of the outer opening pull plate 21 is self-locked, and the other end of the sliding arm 313 away from the second claw 211 enters the bottom end of the wheel 311 and is movably connected with the eccentric seat 312. When the motor 4 is energized, it drives the first full gear 41 to rotate. The first full gear 41 meshes with the driven half gear 42 to rotate. When the driven half gear 42 drives the A drive shaft 3A to rotate, the A drive shaft 3A will drive the wheel 311 to rotate. The wheel 311 will drive the eccentric seat 312 to rotate. When the eccentric seat 312 rotates to contact the inner end of the sliding arm 313, it will drive the sliding arm 313 to move linearly along the slide rail on the slide frame 102. For example, when the sliding arm 313 moves in the direction of the outward opening pull plate 21, it will trigger the closing of the moving part of the lock body 7 with the fixed part of the lock body (half lock or full lock). When fully locked (the linear stroke of the sliding arm 313 is larger). The outer end of the sliding arm 313 will touch the opening part 212 of the second pawl 211, causing the outward opening pull plate 21 to rotate counterclockwise, and the third pawl 211 to tighten the first torsion spring 214; conversely, when the motor 4 rotates in the opposite direction and the sliding arm 313 moves away from the outward opening pull plate 21, the moving part of the lock body 7 separates from the fixed part of the lock body 7 (unlocking or half-opening). When fully open (the reverse linear stroke of the sliding arm 313 is large), the outer end of the sliding arm 313 separates from the opening part 212 of the second pawl 211, the third pawl 211 relaxes and returns to its original position, and the outward opening pull plate 21 rotates counterclockwise by dragging. When fully locked, the outer end of the sliding arm 313 touches the opening part 212 of the second pawl 211, forming a restriction. Therefore, the operator operates the first pawl 211 (external operation) through the outer slot 101, causing the external opening pull plate 21 to rotate the opening part 212 clockwise. At this time, the opening part 212 pushes away the restriction force of the outer end of the sliding arm 313, forcing the sliding arm 313 to retract in the opposite direction. The sliding arm 313 pushes the eccentric seat 312 to rotate clockwise, and the eccentric seat 312 drives the wheel 311 to rotate clockwise, thereby releasing the restriction and completing the external operation unlocking mode.

[0026] In another embodiment, the inward-opening pull plate 22 is vertically mounted on the outer casing 1. An inner groove is provided on one end of the outer casing 1. One end of the inward-opening pull plate 22 extends into the inner groove, and the other end extends into one end of the drive plate. An arc-shaped triggering part is provided between the inward-opening pull plate 22 and the drive plate, triggering a connection. The other end of the drive plate is connected to the lock body. The drive plate, similar to the sliding arm 313 in outward-opening locks, serves as a bridge component for separating the movable and fixed parts of the lock body 7 during inward opening (outward opening). During inward opening, the inward-opening pull plate 22 is operated, causing one end with the arc-shaped triggering part to deflect downwards and contact the drive plate, triggering the drive plate to rotate. The drive plate then triggers the separation of the movable and fixed parts of the lock body 7 (inward opening). A second torsion spring 321 is provided between the drive plate and its mounting point on the outer casing 1. When the inward-opening pull plate 22 is reversed upwards, the arc-shaped triggering part of the inward-opening pull plate 22 separates from the drive plate, the second torsion spring 321 contracts, and pulls the drive plate back to its reset position.

[0027] In another embodiment, the outer casing 1 also includes a circuit board 5, on which a control module 6 is electrically connected to the motor 4. The control module 6 is divided into three units, including a first attitude sensor 61 positioned relative to the outward-opening pull plate 21 (outward opening), a first attitude sensor 61 positioned relative to the inward-opening pull plate 22 (inward opening), and a second attitude sensor 63 positioned relative to the manual unlocking cylinder 23 (lock cylinder open). When unlocking via the outward-opening pull plate 21 (outward opening), the first attitude sensor 61 sends a signal to the motor 4, which can activate the motor 4 to rotate in the reverse direction, thus intelligently unlocking the lock body 7. When unlocking via the inward-opening pull plate 22 (inward opening), the signal interface 62 sends a signal to the motor 4, which can also activate the motor 4 to rotate in the reverse direction, thus intelligently unlocking the lock body 7. Similarly, when unlocking via the manual unlocking cylinder 23, the second attitude sensor 63 sends a signal to the motor 4, which can also activate the motor 4 to rotate in the reverse direction, thus intelligently unlocking the lock body 7. All three manual unlocking modes can trigger the motor 4 to switch from the locking mode to the unlocking mode, improving unlocking efficiency.

[0028] Specifically: a first attitude sensor 61, whose sensing end is positioned relative to the movement trajectory of the outward opening pull plate 21 and the movement trajectory of the inward opening pull plate 22, is used to detect the displacement of the inward opening pull plate 22 and generate an inward opening trigger signal, and to detect the displacement of the outward opening pull plate 21 and generate an outward opening trigger signal; a second attitude sensor 63, whose sensing end is positioned relative to the rotating part of the manual unlocking cylinder 23, is used to detect the rotation angle of the manual unlocking cylinder 23 and generate a manual emergency signal; and the circuit board 5 is configured such that: when the first attitude sensor 61 outputs a trigger signal, the drive motor 4 rotates in a preset direction, driving the lock body 7 to unlock via drive shaft A 3A and driven half gear 42; when the second attitude sensor 63 outputs a manual emergency signal, the power supply circuit of the motor 4 is forcibly cut off, allowing the manual unlocking cylinder 23 to independently drive the lock body 7 to unlock via drive shaft B 3B and linkage mechanism 24; when fully locked, an external third-party remote control device causes the motor 4 to be corner-locked (full locking ±90° (full lock) corner control), achieving anti-theft.

[0029] It should be further noted that the lock body 7 mentioned in this invention is existing technology for smart locks. It locks when a trigger relationship occurs and unlocks when the trigger relationship disappears. This locking and unlocking principle is existing technology and will not be elaborated further. However, this invention achieves a functional improvement through the integration of mechanical structures. If the interference between actions is controlled by the motor 4, it becomes possible. Therefore, based on this, this invention also proposes a preferred scheme for configuring the motor execution information database according to priority selection, to cope with emergencies or meet personalized user needs.

[0030] The control module is configured with a configuration strategy and a control strategy. The configuration strategy includes: Step S1: Obtain the current state until the preset standard conditions are met, then proceed to step S2. The standard conditions include attitude standard conditions and control standard conditions. The attitude standard conditions are configured to obtain the state information of the first attitude sensor and the second attitude sensor until the preset attitude information baseline is met. The control standard conditions are to obtain the corresponding configuration permission command from the signal interface. There are two ways to enter the configuration step, but the permissions they allow for differ, meaning the scope of the priority tags for the configuration step is different. Theoretically, configuration through attitude detection has a wider range of priority tags. If the configuration conditions are not met, the control module will not proceed to the next step.

[0031] Step S2: Obtain the state information of the first posture sensor until a corresponding configuration action is matched in the action matching library; then, obtain the posture of the two action parts through the first posture sensor. This posture needs to be matched with the corresponding posture in the action matching library. The action matching library is pre-built. For example, specific rotation angles and specific touch methods, such as long press and continuous tap, can be configuration actions in the action matching library. However, it should be noted that the action cannot conflict with existing basic actions. That is, the construction of the action matching library follows two elements: first, there cannot be any basic actions. That is, basic actions such as opening and closing doors cannot be configured again to avoid logical conflicts; second, the action must meet the recognition standard. For example, if there is already a double-touch action, no other tap actions will be set. In this way, actions with different priorities can be agreed upon according to user habits, and different priority labels determine the action feedback in different scenarios.

[0032] Step S3: Configure the corresponding priority label for the configuration action based on the status information of the second attitude sensor; the second attitude sensor can be manually rotated to configure different priority labels, such as setting the priority to the highest, the lowest, or in situations such as emergency events. Priorities can also be set based on other feedback signals, and as the new energy vehicle can monitor more information, the number of priority labels can also be increased.

[0033] Step S4: Configure the action and its corresponding priority label in the motor execution information database. This completes the priority setting for a specific action corresponding to a specific scenario. When this action is executed, the handle will receive the instruction. It should be noted that this priority relationship is not sent after data processing by the car terminal, so it does not rely on the car terminal's communication. The advantage of this is that after configuration, problems with the car terminal's communication, data processing, or damage can prevent door lock malfunctions. It also meets the user's adaptability needs. In the event of an emergency, such as when the car is flooded, the terminal itself cannot perform underwater judgment and communication actions if it is flooded. In this case, based on the judgment of the flood situation, the rear seat handle can still assist in opening the door via the motor. Therefore, in emergency situations, independent data processing and logical judgment capabilities are particularly important for car door handles.

[0034] Step S5: Return to step S1; The control strategy includes: Step A1: Obtain the current status information of the first attitude sensor to match the corresponding priority label from the motor execution library; the corresponding priority label can be obtained through user actions, and the priority label must execute the corresponding signal according to the actual environmental conditions. For example, if the action of the first attitude sensor is to open the door, but the priority label shows that the door can only be opened under certain conditions, then this action will be ignored. Conversely, if the priority label shows that the door opening action is executed first in all cases, then the motor will prioritize assisting in opening the door regardless of its state.

[0035] Step A2: Obtain the current environmental feedback signal to generate a state execution command based on the priority label. The controller controls the motor to work in the target state according to the state execution command. For example, when there is a car nearby or a car approaching from behind, the door cannot be opened by monitoring the signal. However, this would affect the comfort of operation. Only families with children can make such a design for safety. This action can be achieved through configuration. By pre-configuring the priority of the door opening action to be reduced, that is, reducing the door opening action to the point that it cannot be opened if there is any risk of opening, and then configuring a new door opening action, the comfort of opening the door for adults can be met. Compared with the traditional child lock function, the scenarios are more diverse and reliable.
