Description

Technical Field

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

[0002] In vehicles, such as cars, all side doors require door handles to open; pulling the door handle opens the door. Currently, in concealed retractable door handles, the base has a first space for the handle to retract and a second space for arranging the door-opening mechanisms after the handle retracts. A person operating the corresponding mechanism within the second space can open the door. This concealed retractable door handle solution requires two independent spaces, and the design must be electrically operated to drive the handle's retraction, making the structure relatively complex. Utility Model Content

[0003] The purpose of this disclosure is to provide a door handle, a door, and a vehicle that at least partially solves the relevant technical problems.

[0004] To achieve the above objectives, according to a first aspect of this disclosure, a door handle is provided, comprising: a base having an operating cavity; a handle rotatably connected to the base; and a mechanical unlocking assembly including a cable and a rotating member rotatably connected to the base. The rotating member is connected to the handle via a transmission assembly, enabling the handle to rotate the rotating member. One end of the cable is connected to the lock body of the vehicle door, and the other end is connected to the rotating member, so that the handle can unlock the vehicle door by driving the cable through the transmission assembly and the rotating member. The door handle, via the rotating member connected to the handle through the transmission assembly, can also rotate, thereby driving the cable connected to the rotating member to unlock the lock body of the vehicle door, thus achieving mechanical unlocking of the door. Furthermore, the base of this door handle has only one operating cavity, and the mechanical unlocking assembly unlocks the door by rotating the handle inward, making it convenient to operate and simple in structure. Simultaneously, this door handle is a concealed door handle that does not protrude from the outer surface of the vehicle door, reducing wind resistance requirements during vehicle operation.

[0005] In some possible embodiments, when the handle is rotated into the operating cavity by a preset angle, the rotating component rotates to the engagement position connected to the cable, thereby pulling the cable to unlock the car door. By setting a preset rotation angle for the handle, the standardization and accuracy of the operation are ensured. The unlocking action is only triggered when the handle is rotated to the appropriate position, effectively avoiding accidental unlocking of the car door due to abnormal operation such as slight shaking of the handle 200, greatly improving the safety and reliability of the door control.

[0006] In some possible embodiments, a sliding groove is formed on the rotating component, and the pull head of the cable is slidably connected within the sliding groove; wherein, the engagement position is the position where the rotating component rotates to the point where the pull head abuts against the end of the sliding groove. On the one hand, this ensures that the handle can be easily flipped inward initially. On the other hand, limiting the engagement position to the state where the pull head abuts against the end of the sliding groove effectively prevents excessive rotation of the rotating component, while providing the operator with a buffer time before applying force to the cable to mechanically unlock the door, allowing for a transition in the operating force and improving the customer experience.

[0007] In some possible embodiments, the handle is rotatably connected to the base via a pivot pin; the transmission assembly includes a first transmission gear and transmission teeth disposed on the rotating component; the first transmission gear is fixedly connected to the pivot pin, and the first transmission gear meshes with the transmission teeth. This achieves stable transmission between handle operation and the rotation of the rotating component; furthermore, through a reasonable gear meshing design, the transmission ratio can be adjusted as needed to optimize the rotational speed and torque output of the rotating component, meeting different operating conditions and improving the overall performance and applicability of the device.

[0008] In some possible embodiments, the handle has a first position, a second position located inside the operating cavity, and a third position, wherein the second position is located between the first position and the third position; in the first position, the handle is located at the opening of the operating cavity; in the second position, the handle rotates into the operating cavity by a preset angle, and the rotating component rotates to an engagement position connected to the cable; in the third position, the cable is used to unlock the car door. This ingenious arrangement and coordination of the three positions makes handle operation smoother and more continuous, effectively improving the convenience and reliability for users when using the door control mechanism, while ensuring the accuracy and stability of the door unlocking action, reducing the risk of door unlocking failure due to improper operation or inaccurate mechanical connection, and improving the overall performance and user experience of the entire door control system.

[0009] In some possible embodiments, the door handle further includes a driving component connected to the rotating component via a transmission structure; the handle also has a first trigger position located between a first position and a second position, with the first trigger position being closer to the first position; when the handle rotates to the first trigger position, the driving component drives the handle to rotate inward from the first trigger position. Through the above configuration, at least part of the handle position is automatically flipped inward, reducing cumbersome actions for the user during operation, improving the convenience and smoothness of operation, and thus optimizing the user's interaction with the door handle, making operations such as opening or closing the door more efficient, natural, and technologically advanced.

[0010] In some possible embodiments, the handle also has an inward-retracted position; the inward-retracted position is located between the second position and the third position, and is closer to the second position; the driving member is connected to the rotating member through a transmission structure, and when the handle rotates to the first trigger position, the driving member drives the handle to rotate from the first trigger position, and then through the second position to the inward-retracted position. The cooperation between the driving member and the transmission structure ensures smoother and more stable transitions between the handle's positions, avoiding jamming or damage that may be caused by uneven manual operation force or angular deviation, thereby effectively extending the service life of the door handle, enhancing its overall reliability and durability, and providing users with a more efficient, comfortable, and stable user experience.

[0011] In some possible embodiments, the door handle further includes a first switch assembly corresponding to the first trigger position, the first switch assembly being electrically connected to the drive member; when the handle is rotated to the first trigger position, the first switch assembly is triggered, and the first switch assembly controls the operation of the drive member. The first switch assembly is precisely positioned at the location corresponding to the first trigger position, ensuring that it can function promptly and accurately under specific conditions.

[0012] In some possible embodiments, the transmission structure includes a cam fixedly connected to the shaft of the driving member, and a mating portion disposed on the rotating member and corresponding to the cam; the cam and the mating portion cooperate, enabling the driving member to drive the rotating member to rotate via the cam and the mating portion. By introducing the mating portion between the cam and the rotating member, the power of the driving member is effectively transmitted to the rotating member.

[0013] In some possible embodiments, the door handle further includes a first reset member, which is connected to both the rotating member and the base, and is used to drive the rotating member and the handle to reset. The first reset member ensures that each component of the door handle accurately returns to its original position after each operation, so that subsequent operations of the door handle are not affected by the previous position, maintaining good operational consistency. Furthermore, it effectively avoids malfunctions such as jamming and damage that may result from components not resetting, extending the service life of the door handle.

[0014] In some possible embodiments, the first reset element is configured to reset the handle after a first preset time following the closing of the vehicle door. By limiting the reset trigger condition of the first reset element to a first preset time following the closing of the vehicle door, the handle reset can be better controlled, improving the user experience.

[0015] In some possible embodiments, the first reset element is further configured to reset the handle after a second preset time following a door closing command; wherein the second preset time is less than the first preset time. By limiting the reset trigger condition of the first reset element to responding to door closing or vehicle central control operation, better control of handle reset can be achieved, improving the user experience.

[0016] In some possible embodiments, the door handle further includes a second trigger position and a second switch assembly corresponding to the second trigger position. When the handle is rotated to the second trigger position, the second switch assembly is triggered, and the electronic unlocking device of the door unlocks the door. The second switch assembly is electrically connected to the electronic unlocking device of the door. When the second switch assembly is triggered, it can send a signal to the electronic unlocking device of the door, thereby enabling the door to be electronically unlocked.

[0017] According to a second aspect of this disclosure, a vehicle door is provided, including the aforementioned door handle. The door handle is mounted on the door body for opening the door; therefore, the vehicle door also possesses all the advantages of the aforementioned concealed door handle.

[0018] According to a third aspect of this disclosure, a vehicle is also provided, including the aforementioned door. Therefore, this vehicle also possesses all the advantages of the aforementioned door.

[0019] With the aforementioned technical solution, namely the door handle of this disclosure, when the handle is rotated into the operating cavity, the rotating component connected to the handle via the transmission assembly also rotates, driving the cable connected to the rotating component to unlock the door lock body, thereby achieving mechanical unlocking of the door. Furthermore, the base of this door handle has only one operating cavity; the mechanical unlocking component unlocks the door by rotating the handle inward, making it convenient to operate and simple in structure. Simultaneously, this door handle is a concealed door handle that does not protrude from the outer surface of the door, reducing wind resistance during vehicle movement.

[0020] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0039] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0040] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of the corresponding components; "far" and "near" refer to the corresponding structure or component being away from or near another structure or component. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0041] All side doors require a door handle to open; pulling the handle opens the door. Door handles are categorized as protruding, semi-concealed, and concealed, with concealed handles reducing overall wind resistance. Currently, most concealed door handles require the handle to extend outwards when operated, while electrically concealed handles with a mechanical opening backup that move inwards are less common.

[0042] The inventors discovered that the base of the concealed retractable door handle has a first space for the handle to retract and a second space for arranging the door opening mechanism after the handle is retracted. The door can be opened by operating the corresponding mechanism with the hand in the second space. In other words, the concealed retractable door handle solution requires two independent spaces, which makes the structure relatively complex and inconvenient to operate.

[0043] Embodiments of this disclosure provide a door handle, a vehicle door, and a vehicle. The door handle is used in the vehicle door and the vehicle. The handle 200 of the door handle mechanically unlocks the vehicle door via a mechanical unlocking assembly 300 by rotating inward (inside the operating cavity 110 of the base 100). This door handle is a concealed door handle designed to reduce wind resistance in automobiles. This type of door handle does not protrude from the outer surface of the vehicle door. The door is unlocked by rotating the handle 200 inward, making it convenient to operate and simple in structure.

[0044] To achieve the above objectives, such as Figures 1 to 9As shown, according to a first aspect of this disclosure, a door handle is provided, comprising a base 100, a handle 200, and a mechanical unlocking assembly 300. The base 100 has an operating cavity 110; the handle 200 is rotatably connected to the base 100. The mechanical unlocking assembly 300 includes a cable 320 and a rotating member 310 rotatably connected to the base 100. The rotating member 310 is connected to the handle 200 via a transmission assembly, enabling the handle 200 to drive the rotating member 310 to rotate. One end of the cable 320 is connected to the lock body of the vehicle door, and the other end is connected to the rotating member 310, so that the handle 200 can unlock the vehicle door by driving the cable 320 through the transmission assembly and the rotating member 310.

[0045] With the above-described technical solution, namely the door handle of this disclosure, when the handle 200 rotates into the operating cavity 110, the rotating component 310 connected to the handle 200 via the transmission assembly also rotates, driving the cable 320 connected to the rotating component 310 to unlock the door lock body, thereby achieving mechanical unlocking of the door. Furthermore, the base 100 of this door handle has only one operating cavity 110; the handle 200 rotates inward to achieve mechanical unlocking of the door by the mechanical unlocking component 300, making operation convenient and the structure simple. At the same time, this door handle is a concealed door handle that does not protrude from the outer surface of the door, which can reduce wind resistance requirements during vehicle operation.

[0046] It should be noted that the base 100 has an open recessed space for the handle 200 to flip inward, forming the aforementioned operating cavity 110. The base 100 can be an injection molded part, and the operating cavity 110 can be integrally injection molded. The handle 200 can be rotatably connected to the operating cavity 110 of the base 100 in any suitable manner, and has a first position P1 that stops at the opening of the operating cavity 110, and can flip inward. During the flipping process, the transmission component drives the rotating component 310 to rotate, and the rotating component 310 drives the connected cable 320, thereby achieving mechanical unlocking of the car door through the cable 320.

[0047] It is understood that the above-mentioned transmission components can be constructed using any suitable structure. For example, they can be gear meshing structures as described in some of the following embodiments, or they can be conveyor belt structures.

[0048] The door handle mainly consists of a base 100, a handle 200, and a mechanical unlocking component 300. The base 100 serves as the basic support for the entire door handle and includes an operating cavity 110, providing space for the handle 200 to fold inwards, while also providing ample and suitable space for the installation and operation of internal components. The handle 200 is rotatably and securely connected to the base 100, and through precise mechanical cooperation, ensures that the handle 200 rotates smoothly within a certain angle range without any jamming, providing the user with a good operating feel.

[0049] The mechanical unlocking component 300 is a key part of the door handle's mechanical unlocking function, and it includes a pull cable 320 and a rotating component 310. The rotating component 310 is also connected to the base 100 via a rotatable connection. This rotatable connection between the rotating component 310 and the base 100 needs to ensure smooth and accurate rotation under load, avoiding any shaking or loosening. The rotating component 310 is connected to the handle 200 via a transmission component. When the handle 200 rotates, the efficient transmission of the transmission component drives the rotating component 310 to rotate. The entire transmission process ensures uniform and stable power transmission without significant lag or loss, thus achieving coordinated action between the handle 200 and the rotating component 310.

[0050] The two ends of the cable 320 play key roles. One end is used to reliably connect to the lock body of the door. It adopts a robust connection structure to ensure that the cable 320 will not loosen or detach from the lock body when under force. The connector at the other end is snapped onto the base 100, and the cable head is connected to the rotating part 310. When the rotating part 310 rotates, the tension of the cable 320 can be transmitted to the door lock body, thereby realizing the door unlocking function.

[0051] In the embodiments disclosed herein, the user can easily unlock the vehicle door by simply rotating the handle 200, thanks to the efficient transmission of the mechanical unlocking component 300. Both the driver and passengers can quickly master the operation method without complicated procedures or additional tools, greatly improving the convenience of unlocking the vehicle door. This convenient operation method saves valuable time, especially in emergencies or when both hands are busy.

[0052] The unlocking process is more reliable. The two ends of the cable 320 are connected to the door lock body and the rotating component 310 respectively, ensuring effective transmission of pulling force. When the handle 200 drives the rotating component 310 to rotate, the cable 320 can quickly and accurately apply pulling force to the door lock body, achieving rapid door unlocking. Compared with other electronic unlocking methods, this mechanical unlocking method has stronger anti-interference capabilities and stability, is unaffected by electromagnetic interference, battery power, or other factors, and can stably perform its unlocking function under various complex environmental conditions, providing strong protection for the safe use of the vehicle.

[0053] In some possible embodiments, when the handle 200 is rotated into the operating cavity 110 by a preset angle, the rotating member 310 rotates to the engagement position connected to the cable 320, thereby pulling the cable 320 to unlock the car door. Specifically, when the user applies force to the handle 200, causing it to rotate into the operating cavity 110, and the rotation angle reaches a specific preset angle value, the rotating member 310 will rotate accordingly under the corresponding action mechanism, precisely reaching the engagement position connected to the cable 320. At this time, the rotating member 310 and the cable 320 form an effective connection, and thus, the traction effect of the cable 320 is used to smoothly achieve the unlocking operation of the car door.

[0054] This design approach offers several advantages. Firstly, by setting a preset rotation angle for the handle 200, the operation is standardized and accurate. The unlocking action is triggered only when the handle 200 is rotated to the appropriate position, effectively preventing accidental door unlocking due to slight shaking or other abnormal operations, thus significantly improving the safety and reliability of door control. Secondly, the precise engagement between the rotating component 310 and the cable 320 ensures that the cable 320 can stably and efficiently transmit the unlocking action, guaranteeing smooth door unlocking and enhancing the user experience. This makes door opening more convenient and faster, meeting users' needs for ease of door opening in real-world scenarios. Furthermore, this rational structural layout and precise action coordination help extend the lifespan of the entire door control device, reducing wear and tear and malfunction risks caused by improper component coordination.

[0055] It should be noted that the preset angle is the angle at which the handle 200 rotates inward from its initial position. This preset angle can be between 30° and 120°, for example, 30°, 45°, 60°, 90°, 120°, etc. When the handle 200 just begins to rotate from its initial position, the rotating component 310 can rotate, but there is no engagement between the rotating component 310 and the cable 320; that is, the cable 320 does not rotate with the rotating component 310. When the handle 200 rotates to the preset angle, the rotating component 310 engages with the cable 320, and the cable 320 rotates with the rotating component 310. As the handle 200 rotates inward, the door is unlocked.

[0056] To achieve the desired effect, after the handle 200 rotates into the operating cavity 110 by a preset angle, the rotating component 310 rotates to the engagement position connected to the cable 320, thereby pulling the cable 320 to unlock the car door. The connection between the rotating component 310 and the cable 320 can be constructed using any suitable structure, such as... Figure 4 and Figure 5As shown, in some possible embodiments, a sliding groove 311 is formed on the rotating member 310, and the pull head of the cable 320 is slidably connected in the sliding groove 311; wherein, the engagement position is the position when the rotating member 310 rotates to the position where the pull head abuts against the end of the sliding groove 311.

[0057] A sliding groove 311 is formed on the rotating component 310, and the pull head of the cable 320 is slidably connected within the sliding groove 311. When the rotating component 310 is in its normal non-engaged state, the pull head can slide relative to it within the sliding groove 311, allowing for flexible movement of the rotating component 310. When engagement is required, the handle 200 is flipped inward, causing the rotating component 310, which is connected to the handle 200 via a transmission assembly, to rotate until the pull head abuts against the end of the sliding groove 311. This specific position of the rotating component 310 is the engagement position. Through this structural design, on the one hand, the sliding connection between the sliding groove 311 and the pull head provides a condition where the rotating component 310 is not engaged with the cable 320 during the initial rotation, ensuring that the handle 200 can be flipped inward relatively easily in the early stages. On the other hand, limiting the engagement position to the state where the pull head abuts against the end of the sliding groove 311 effectively prevents the rotating part 310 from rotating excessively. It also provides the operator with a buffer time before applying force to the cable 320 to mechanically unlock the door, allowing for a transition in the operating force and improving the customer experience. Simultaneously, space is reserved for electric unlocking, facilitating the dual implementation of electronic and mechanical unlocking, providing users with a more reliable and efficient product experience.

[0058] The transmission components can be constructed using any suitable structure, such as Figure 1 , Figure 5 and Figure 6 As shown, in some possible embodiments, the handle 200 is rotatably connected to the base 100 via a shaft pin 500; the transmission assembly includes a first transmission gear 510 and a transmission tooth 312 disposed on the rotating member 310; the first transmission gear 510 is fixedly connected to the shaft pin 500, and the first transmission gear 510 meshes with the transmission tooth 312.

[0059] The handle 200 is rotatably connected to the base 100 via a pivot pin 500. The handle 200 is fixedly connected to the pivot pin 500, and both ends of the pivot pin 500 are rotatably connected to both ends of the operating cavity 110 of the base 100, respectively passing through the opposite side walls of the operating cavity 110. This allows the handle 200 to rotate flexibly relative to the base 100, providing the user with a convenient manual control method. The transmission assembly can be constructed as follows: it includes a first transmission gear 510 and transmission teeth 312 disposed on the rotating component 310. The first transmission gear 510 is fixedly mounted on the pivot pin 500, meaning that a reliable fixing method is used on the pivot pin 500 to ensure that the first transmission gear 510 rotates synchronously with the pivot pin 500. The first transmission gear 510 meshes with the transmission gear 312. Thus, when the handle 200 drives the shaft pin 500 to rotate, the first transmission gear 510, which is fixedly connected to the shaft pin 500, rotates accordingly. Through the meshing relationship with the transmission gear 312, the rotational torque can be transmitted to the rotating component 310, thereby driving the rotating component 310 to achieve the expected rotational function.

[0060] The technical solution of this embodiment has significant effects: on the one hand, it realizes stable transmission between the operation of the handle 200 and the rotation of the rotating component 310, ensuring the reliability of power transmission and effectively avoiding slippage or jamming during transmission; on the other hand, through reasonable gear meshing design, the transmission ratio can be adjusted as needed to optimize the rotation speed and torque output of the rotating component 310, meet the requirements of different operating conditions, and improve the performance and applicability of the entire device.

[0061] like Figure 3 As shown, in some possible embodiments, the handle 200 has a first position P1, a second position P3 located inside the operating cavity 110, and a third position P6, wherein the second position P3 is located between the first position P1 and the third position P6; in the first position P1, the handle 200 is located at the opening of the operating cavity 110; in the second position P3, the handle 200 is rotated into the operating cavity 110 by a preset angle, and the rotating member 310 is rotated to an engagement position connected to the cable 320; in the third position P6, the cable 320 is used to unlock the car door.

[0062] The door handle 200 has a first position P1, a second position P3, and a third position P6. The second position P3 is located inside the operating cavity 110, between the first position P1 and the third position P6. When the handle 200 is in the first position P1, it is positioned at the opening of the operating cavity 110, in an initial standby state, facilitating user operation and concealing internal components, thus improving the overall aesthetics of the door. When the handle 200 is in the second position P3, it rotates into the operating cavity 110 by a preset angle (referring to the corresponding angle in the above embodiment). Simultaneously, the associated rotating component 310 precisely rotates to its engagement position with the cable 320, ensuring a stable and effective mechanical connection and providing reliable support for subsequent action transmission. When the handle 200 is in the third position P6, the cable 320 operates according to a preset motion logic, fulfilling its key function of unlocking the door and achieving precise switching between the locked and unlocked states. Through the ingenious arrangement and coordination of these three positions, the operation of the handle 200 becomes smoother and more continuous, effectively improving the convenience and reliability for users when using the door control mechanism. At the same time, it ensures the accuracy and stability of the door unlocking action, reduces the risk of door unlocking failure due to improper operation or inaccurate mechanical connection, and improves the overall performance and user experience of the entire door control system.

[0063] like Figure 3 As shown, in some possible embodiments, the door handle further includes a drive member 400, which is connected to the rotating member 310 via a transmission structure. The handle 200 also has a first trigger position P2, which is located between the first position P1 and the second position P3, and is closer to the first position P1. When the handle 200 rotates to the first trigger position P2, the drive member 400 drives the handle 200 to rotate inward from the first trigger position P2. The handle 200 can be flipped inward from the first position P1 to the trigger position P2 by a person pushing it. Here, the drive member 400 can receive a trigger signal and start working, driving the handle 200 to rotate inward by a certain angle, for example, it can be flipped to a certain position inside the operating cavity 110 (for example, it can be flipped to a position with an angle greater than the second position P3). When the person pushes the handle 200 inward again to rotate it, the handle 200 continues to drive the rotating member 310 to rotate to the third position P6, thereby realizing the mechanical unlocking of the car door. Through the above settings, at least part of the handle at position 200 is automatically flipped inward, reducing cumbersome actions for the user during operation, improving the convenience and smoothness of operation, and thus optimizing the interaction experience between the user and the door handle, making operations such as opening or closing the door more efficient, natural and technologically advanced.

[0064] like Figure 3 As shown, in some possible embodiments, the handle 200 further has a first trigger position P2 and an inward position P4; the first trigger position P2 is located between the first position P1 and the second position P3, and the inward position P4 is located between the second position P3 and the third position P6, with the first trigger position P2 closer to the first position P1 and the inward position P4 closer to the second position P3; the door handle also includes a drive member 400, which is connected to the rotating member 310 through a transmission structure. When the handle 200 rotates to the first trigger position P2, the drive member 400 drives the handle 200 to rotate from the first trigger position P2, and then rotates through the second position P3 to the inward position P4. In addition to having the first position P1, the second position P3, and the second position P3, the handle 200 may also have a first trigger position P2 and an inward position P4. The first trigger position P2 is located in the area between the first position P1 and the second position P3, while the inward position P4 is located within the range between the second position P3 and the third position P6. Furthermore, the first trigger position P2 is adjacent to the first position P1, that is, the rotation angle between the first trigger position P2 and the first position P1 is smaller than the rotation angle between the first trigger position P2 and the second position P3; the inward position P4 is close to the second position P3, that is, it is set close to the second position P3.

[0065] To further enhance the operability and user experience of the door handle, a drive component 400 or actuator is added. The drive component 400 is connected to the rotating component 310 via a transmission structure, forming a coordinated transmission system. When the handle 200 precisely rotates to the first trigger position P2 according to the preset rotation trajectory, the drive component 400 begins to function. It drives the handle 200 from the first trigger position P2, sequentially through the second position P3, and finally to the retracted position P4. When the handle 200 reaches the second position P3, the rotating component 310 is engaged with the cable 320. Driven by the drive component 400, the handle 200 rotates from the second position P3 to the retracted position P4. Simultaneously, the rotating component 310 also drives the cable 320 to gradually unlock the door. This design allows the handle 200 to achieve automated, continuous movement during operation, eliminating the need for the user to manually adjust the handle 200 from the second position P3 to the retracted position P4, simplifying the operation process and improving ease of use. Meanwhile, the cooperation between the drive component 400 and the transmission structure ensures that the handle 200 can switch between various positions more smoothly and stably, avoiding jamming or damage caused by uneven manual operation force or angle deviation. This effectively extends the service life of the door handle, enhances its overall reliability and durability, and provides users with a more efficient, comfortable and stable user experience.

[0066] In order to automatically control the drive unit 400 to work when the handle 200 reaches the first trigger position P2, such as... Figure 3 , Figure 5 and Figure 6 As shown, in some possible embodiments, the door handle may also include a first switch assembly 610 corresponding to the first trigger position P2, the first switch assembly 610 being electrically connected to the drive member 400; when the handle 200 is rotated to the first trigger position P2, the first switch assembly 610 is triggered, and the first switch assembly 610 controls the drive member 400 to work.

[0067] The first switch assembly 610 plays a crucial role in the overall structure of the door handle. Its precise placement corresponds to the first trigger position P2, ensuring timely and accurate operation under specific conditions. When the handle 200 rotates to the first trigger position P2, the first switch assembly 610 is activated. This activation can be achieved through a direct or indirect mechanical linkage between the handle 200 and the first switch assembly 610. When the handle 200 reaches the predetermined rotation position, a specific structure on it contacts or engages with the first switch assembly 610, changing the internal state of the first switch assembly 610 and thus achieving the activation function.

[0068] In order to trigger the first switch assembly 610, in some embodiments of this disclosure, triggering the first switch assembly 610 using the handle 200 means that the first switch assembly 610 can be triggered directly through the handle 200, or the first switch assembly 610 can be triggered using the trigger member 520 connected to the handle 200 or the shaft pin 500.

[0069] like Figure 1 As shown, the first switch assembly 610 is triggered by a trigger member 520 mounted on the pivot pin 500. Similarly, the second switch assembly 620 described below is also arranged on the movement trajectory of the trigger member 520. When the trigger member 520 rotates to the second trigger position P5 corresponding to the handle 200, the second switch assembly 620 is triggered, thereby realizing the electronic unlocking of the door.

[0070] To achieve precise control of the door handle's movement, a first switch assembly 610 is positioned at the first trigger position P2 and electrically connected to the drive component 400. When the handle 200 rotates to the first trigger position P2, the first switch assembly 610 can sensitively sense this change in movement and immediately transmit an electrical signal to the drive component 400, thereby achieving precise control of the drive component 400. The drive component 400 may include, for example, a motor or other power component that starts operating, transmitting power to the handle 200 or the shaft pin 500 connected to the handle 200 via a transmission device such as gears or connecting rods, thereby driving the handle 200 to rotate from the first trigger position P2 to the inward position P4.

[0071] First, by setting the first switch assembly 610 at the first trigger position P2, the instant the handle 200 reaches the first trigger position P2 can be accurately identified, providing a reliable trigger signal for subsequent automatic actions and greatly improving the intelligence level of the door handle operation. Second, the electrical connection between the first switch assembly 610 and the drive component 400 ensures the speed and accuracy of signal transmission, enabling the handle 200 to quickly and smoothly rotate from the first trigger position P2 to the retracted position P4, optimizing the user's operating experience. Furthermore, this precise control mechanism effectively reduces the dwell time of the handle 200 in unexpected positions, lowering the possibility of component wear or jamming due to misoperation, further improving the overall reliability and service life of the door handle, and enhancing its stability and practicality in real-world applications.

[0072] It should be noted that the first switching assembly 610 may include limit switches, micro switches, proximity switches, or Hall switches, etc. It may also be a sensor or other device known in the related art, which can communicate with the driving component 400 via wired or wireless connection.

[0073] The transmission structure can be constructed using any suitable structure, such as... Figure 2 , Figure 5 and Figure 6 As shown, in some possible embodiments, the transmission structure may include a cam 410 fixedly connected to the shaft of the drive member 400, and a mating part 313 provided on the rotating member 310 and corresponding to the cam 410; the cam 410 and the mating part 313 cooperate so that the drive member 400 can drive the rotating member 310 to rotate through the cam 410 and the mating part 313.

[0074] The cam 410 is fixedly connected to the shaft of the drive member 400 through machining or other suitable connection methods, thereby ensuring synchronous movement between the two and allowing the cam 410 to rotate synchronously with the rotation of the drive member 400. The rotating member 310 is also provided with or has a mating part 313 adapted to the cam 410. The two achieve a tight transmission fit through precise shape matching and positional arrangement. For example, when the handle 200 is rotated to the first trigger position P2, the cam 410 and the mating part 313 are perfectly engaged. When the drive member 400 rotates, the cam 410 rotates accordingly and interacts with the mating part 313 of the rotating member 310, thereby driving the rotating member 310 to rotate around its own axis, further driving the cable 320 to rotate to the third position P6 to achieve mechanical unlocking of the door.

[0075] This transmission structure design, by introducing the mating part 313 between the cam 410 and the rotating component 310, and further reconfiguring the meshing of the transmission gear 312 of the transmission assembly with the first transmission gear 510, allows the drive component 400 to pull the cable 320 by driving the rotating component 310 to rotate, and simultaneously drive the handle 200 to rotate into the operating cavity 110. This enables more precise and smooth force transmission, ensuring the stability and reliability of the transmission process. The precise matching of the shape of the cam 410 and the mating surface allows the rotational motion of the drive component 400 to be effectively converted into the rotation of the rotating component 310 during the rotation of the drive component 400, thereby improving the motion accuracy and response speed of the entire transmission system. Secondly, this multi-component collaborative transmission method allows for more flexible and diverse transmission paths, facilitating optimization and adjustment according to actual structural layout and space constraints, thus improving the system's adaptability and integration. Furthermore, by rationally designing the shape curve of the cam 410 and the parameters of the mating surface, effective control of transmission speed and torque can be achieved to a certain extent, meeting the usage requirements under different working conditions, and further expanding the function and application range of the door handle system.

[0076] It should be noted that the mating part 313 of the rotating member 310 can be any suitable structure provided on one side of the transmission tooth 312 of the rotating member 310. For example, it can be a stop arm, which has a mating surface that abuts against the cam 410 and can realize the rotation of the rotating member 310 under the push of the cam 410.

[0077] In some possible embodiments, the door handle further includes a first reset member 420, which is connected to the rotating member 310 and the base 100 respectively, for driving the rotating member 310 and the handle 200 to reset.

[0078] The first reset component 420 is connected to both the rotating component 310 and the base 100. The first reset component 420 includes, but is not limited to, a reset spring or a torsion spring. When the first reset component 420 is a reset spring, it can be sleeved on the rotating shaft inside the rotating component 310, with one end connected to the base 100 and the other end connected to the rotating component 310. Its working principle is as follows: when the door handle 200 rotates from the first position P1 to the second position P3 or the third position P6 (including when the driving component 400 drives the rotating component 310 to rotate), the first reset component 420 stores force. After the driving component 400 stops working, the first reset component 420 can promptly exert its elasticity or restoring force, causing the rotating component 310 to reset. Simultaneously, the rotating component 310 and the first transmission gear 510 drive the shaft pin 500 and the handle 200 to return to the initial first position P1, achieving a precise and stable reset function.

[0079] The first reset component 420 ensures that all parts of the door handle accurately return to their original positions after each operation, preventing subsequent operations from being affected by the previous position and maintaining consistent operation. Furthermore, it effectively avoids malfunctions such as jamming and damage that may result from parts not being reset, extending the door handle's lifespan. Moreover, for a smooth user experience, the reset process makes opening and closing the door more natural and fluid, improving overall comfort and convenience, and enhancing the door handle's reliability and stability in practical applications.

[0080] In some possible embodiments, the first reset element 420 is configured to reset the handle 200 in response to a first preset time after the door is closed. The reset process of the first reset element 420 can be triggered after the first preset time after the door is closed. This first preset time can be 0.1S-5S, and can be set as needed. For example, the first preset time can be 0.1S, 0.2S, 0.3S, 0.4S, 0.5S, 0.6S, 0.7S, 0.8S, 0.9S, 1S, 2S, 3S, 4S, 5S, etc. By limiting the reset trigger condition of the first reset element 420, the handle reset can be better controlled, improving the user experience. It should be noted that the first reset element 420 functions throughout the process of the handle resetting from the third position P6 to the first position P1. Simultaneously, it can cooperate with the drive element 400 (e.g., the drive element 410 drives the rotating element 310 to rotate in the opposite direction) to achieve the reset of the handle 200.

[0081] In some possible embodiments, the first reset element 420 is further configured to reset the handle 200 after a second preset time following the issuance of a door closing command; wherein the second preset time is less than the first preset time. The door closing command can be a user-initiated closing command, such as a control closing command sent on the vehicle control panel or other in-vehicle control devices, or even a mobile terminal. The reset process of the first reset element 420 can also be triggered after a second preset time following the door closing command operated on the vehicle control panel. This second preset time can be 0.1S-4S, and can be set as needed. However, it should be noted that the second preset time is less than the first preset time, so that when both conditions are met simultaneously, the response to the vehicle's central control operation is triggered faster. For example, the second preset time can be 0.1S, 0.2S, 0.3S, 0.4S, 0.5S, 0.6S, 0.7S, 0.8S, 0.9S, 1S, 2S, 3S, 4S, etc. For example, the first preset duration can be 1 second, and the second preset duration can be 0.5 seconds. By further defining the reset trigger condition of the first reset element 420, the trigger of the first reset element 420 can respond to the closing of the car door or to the operation of the vehicle control screen or mobile terminal. This is used to better control the handle reset and improve the user experience. It should be noted that the first reset element 420 is active during the process of the handle resetting from the third position P6 to the first position P1. In addition, it can also cooperate with the drive element 400 (for example, the drive element 400 drives the rotating element 310 to rotate in the opposite direction through the cam 410) to realize the reset of the handle 200.

[0082] It should be noted that during the reset process, the drive unit 400 is not forcibly executed. In some scenarios, such as when a hand is in the operating cavity 110, the drive unit 400 will rotate in the opposite direction on its own, but the handle 200 will not be driven to avoid pinching the hand.

[0083] In some possible embodiments, the drive element 400 is further configured to, under preset conditions, drive the handle 200 to rotate from the first position P1 to the retracted position P4. The drive element 400 may be equipped with a control unit, which can precisely drive the handle 200 to change positions based on preset parameter thresholds, time sequences, or external signal triggering conditions. This design allows the device to switch the position of the handle 200 without manual intervention during automated operation, based on a predetermined program or real-time monitored status requirements, greatly improving the ease of operation and efficiency of the device. Simultaneously, because the drive element 400's movements are precise and stable, it effectively ensures the accuracy and reliability of the handle 200 during position changes, thereby ensuring that other components or functional modules associated with the handle 200 can work collaboratively, optimizing the overall performance and lifespan of the device.

[0084] In addition, the drive unit 400 can also communicate with the vehicle's control unit. The preset condition can be that when the vehicle control unit detects the car key entering a preset range within the vehicle, it controls the drive unit 400 to switch from the first position P1 to the retracted position P4. Alternatively, the preset condition can be relevant information sent by an application on an electronic device (e.g., a mobile phone) to the vehicle's control unit or the drive unit 400's control unit to control the drive unit 400's operation.

[0085] like Figure 1 , Figure 5 and Figure 6 As shown, in some possible embodiments, the door handle further includes a second trigger position P5 and a second switch assembly 620 corresponding to the second trigger position P5. The second switch assembly 620 is electrically connected to the electronic unlocking mechanism of the door. When the handle 200 is rotated to the second trigger position P5, the second switch assembly 620 is triggered, and the electronic unlocking mechanism of the door unlocks the door. The second trigger position P5 may correspond to an inward position P4, a third position P6, or be located between the inward position P4 and the third position P6. When the handle 200 is rotated to the second trigger position P5, it can trigger the electronic unlocking mechanism of the door to electronically unlock the door.

[0086] like Figure 1 and Figure 3 As shown, the second trigger position P5 can be set between the retracted position P4 and the third position P6, and a second switch assembly 620 is set in the area corresponding to the second trigger position P5. When the handle 200 is rotated to the second trigger position P5, the handle 200 or the trigger element 520 mounted on the shaft pin 500 can trigger the second switch assembly 620. The second switch assembly 620 is electrically connected to the electronic unlocking device of the door. When the second switch assembly 620 is triggered, it can send a signal to the electronic unlocking device of the door, thereby realizing the electronic unlocking of the door. The second switch assembly 620 adopts advanced electrical connection technology and establishes a stable and reliable electrical connection with the electronic unlocking device of the door.

[0087] When the user applies external force to precisely rotate the handle 200 to the second trigger position P5 along a preset rotation trajectory, the handle 200 triggers the second switch assembly 620. At the moment of triggering, the second switch assembly 620 quickly transmits an electrical signal to the electronic unlocking mechanism of the door, causing the electronic unlocking mechanism to accurately and promptly perform the unlocking operation, thus enabling convenient door opening. This structural design achieves precise linkage between the electronic door unlocking operation and the position of the handle 200, greatly improving the accuracy and reliability of the operation and avoiding the possibility of misoperation. The electrical connection method ensures rapid and stable signal transmission, completing the entire process from the rotation of the handle 200 to door unlocking in a very short time, effectively improving the efficiency and convenience of door opening, providing users with a smoother and more natural user experience, and also enhancing the overall intelligence and human-centered design level of the vehicle.

[0088] It should be noted that the vehicle has a normal mode and an extreme mode (e.g., a collision mode). In normal mode, the second switch assembly 620 corresponding to the second trigger position P5 is activated when the handle 200 is rotated to the second trigger position P5. The handle 200 contacts the door's electronic unlocking mechanism via the shaft pin 500, the first transmission gear 510, the rotating member 310, and the cable 320, and can be electrically connected to the second switch assembly 620 to unlock the door. In this mode, the mechanical unlocking function can be disabled in the third position P6.

[0089] In extreme modes, such as collision scenarios, the electronic unlocking mechanism of the car door fails. In this case, the handle 200 needs to be rotated all the way to the third position P6 to mechanically unlock the car door through the mechanical unlocking component 300 (rotating component 310 and cable 320).

[0090] It should be noted that, for example, in collision scenarios:

[0091] The door handle drive mechanism (drive component 400) will drive the door handle to return to its original position. If it does not return to its original position, the return process will be repeated multiple times. For example, it will repeat the return process three or more times.

[0092] The inward tilting function of the door handle 200 is temporarily disabled, including disabling the operation of the internal and external electric release buttons, as well as disabling the external door handle drive mechanism. Internal unlocking events such as unlocking in P position will not trigger the door handle to tilt inward.

[0093] After a period of time following the collision, such as 3-8 seconds, for example, 5 seconds, the electric release button will resume operation.

[0094] If the electric release is still effective, when the handle 200 is flipped inward to the second trigger position P5, the second switch assembly 620 is triggered to control the electronic unlocking mechanism of the door to achieve electronic unlocking.

[0095] If the electric release fails, the handle 200 can be flipped to the third position P6 to mechanically unlock using the mechanical unlocking component 300. Simultaneously, an alarm will be triggered to the user, via methods including but not limited to text display on the vehicle's control screen and voice prompts.

[0096] In this embodiment, the handle 200 is mounted on the base 100 via a pivot pin 500. The trigger 520 and the first transmission gear 510 pass through the pivot pin 500 and are mounted together with the handle 200, so that the trigger 520, the first transmission gear 510, and the handle 200 can rotate synchronously with the pivot pin 500. The first switch assembly 610 and the second switch assembly 620 are both mounted on the base 100 and correspond to the first trigger position P2 and the second trigger position P5, respectively. The first reset member 420 (e.g., a spring) is mounted inside the rotating member 310 and is mounted on the base 100 via a rotating pin that mounts the rotating member 310. The cam 410 is connected to the shaft of the drive member 400 or the actuator. The drive member 400 is rotatably mounted on the base 100 via a pin. A sliding groove 311 is formed on the rotating member 310. The pull head of the cable 320 is slidably connected inside the sliding groove 311. The connector on the outside of the cable 320 is fixed to the base 100. By rotating the rotating member 310, the pull head of the cable 320 can be pulled together with the end of the sliding groove 311, thereby pulling the cable 320 to achieve mechanical unlocking of the car door.

[0097] The specific operation process includes: the user can push the handle 200 in the first position P1 inward with their hand. When the handle 200 rotates to the first trigger position P2, the first switch assembly 610 is triggered. The drive member 400 drives the cam 410 to rotate. The cam 410 cooperates with the mating part 313 of the rotating member 310 to drive the rotating member 310 to rotate. At the same time, the transmission gear 312 of the rotating member 310 pushes the first transmission gear 510 wheel that cooperates with it to rotate, thereby driving the shaft pin 500 to rotate. The handle 200 on the shaft pin 500 rotates inward. When rotating from the first trigger position P2 to the second position P3, the rotating member 310 rotates to the engagement position connected to the cable 320. The rotating member 310 continues to rotate, thereby driving the cable 320 to gradually unlock the car door. When the handle 200 rotates to the retracted position P4, the drive member 400 can stop working. At this time, the user pushes the handle 200 inward with their hand so that the handle 200 moves to the third position P6, and the cable 320 realizes the mechanical unlocking of the car door.

[0098] Furthermore, when the handle 200 has a second trigger position P5 and the second switch assembly 620 is arranged in the second trigger position P5, the second switch assembly 620 controls the electronic unlocking structure of the door to electronically unlock the door.

[0099] When the person releases the handle 200, the rotating part 310 first resets under the action of the first reset part 420, and at the same time, drives the handle 200 to reset from the third position P6 to the first position P1.

[0100] According to the description of the above embodiments, the retractable mode of the door handle may also include the following situations.

[0101] Handle 200 inward retraction mode 1: When a person approaches the vehicle, the entire vehicle can automatically unlock, and the drive unit 400 (actuator) starts operating, driving the handle 200 to rotate from the first position P1 to the inward retraction position P4. Simultaneously, the rotating component 310 drives the cable 320 to mechanically unlock the door (the door is not unlocked). In this case, the drive unit 400 can be controlled via the car key carried by the person or the electronic device they possess (such as a mobile phone). The subsequent mechanical unlocking process requires the person to push the handle 200 inward; when the handle 200 reaches the third position P6, the door unlocks.

[0102] Handle 200 inward retraction mode two: When a person approaches the vehicle, the entire vehicle can be automatically unlocked. Handle 200 will not electrically flip inward. After manually pushing handle 200 from the first position P1 to the first trigger position P2, the first switch component 610 (microswitch) is triggered, and the drive component 400 (actuator) starts to operate, driving handle 200 to the inward retraction position P4. The subsequent mechanical unlocking process requires manual pushing of handle 200 inward. When handle 200 reaches the third position P6, the door is unlocked.

[0103] According to the description of the above embodiments, the opening method of the door of a vehicle having the door handle may also include the following.

[0104] Car door opening method 1:

[0105] After the handle 200 reaches the retracted position P4, manually operate the handle 200 and push it at a small angle to the second trigger position P5 to trigger the second switch assembly 620. The second switch assembly 620 sends an electrical signal to the electronic unlocking component of the door to realize the electrical signal door opening.

[0106] Car door opening method two:

[0107] After the handle 200 reaches the retracted position P4, manually operate the handle 200 and push it at a large angle to the third position P6. During the pushing process, the handle 200 drives the rotating part 310 to continue to rotate, thereby driving the cable 320 to continue to mechanically unlock the car door until the car door is opened, realizing the purely mechanical opening of the car door.

[0108] It should be noted that this door handle can be used in both normal and extreme modes. Normal mode refers to a vehicle in a normal state, meaning the battery is charged and the vehicle is usable. Extreme mode refers to situations such as a collision or partial battery depletion. The door handle can only switch to mechanical unlocking in extreme mode, enabling mechanical unlocking of the door. In normal mode, the door can be unlocked electronically. Understandably, in other modes, both electronic and mechanical unlocking methods can be used simultaneously to unlock the door.

[0109] According to a second aspect of this disclosure, a vehicle door is provided, including a door body and the aforementioned door handle. The door handle is mounted on the door body for opening the vehicle door; therefore, the vehicle door also possesses all the advantages of the aforementioned concealed door handle, which will not be elaborated further here.

[0110] According to a third aspect of this disclosure, a vehicle is also provided, including the aforementioned door. Therefore, this vehicle also possesses all the advantages of a door, which will not be elaborated further here. The vehicle may further include a control unit and an actuation component for unlocking and locking the door, for example, including a drive component and a latch, for cooperating with a second switch component 620620 of the door handle to achieve electronic locking and unlocking of the door.

[0111] The disclosed door handle, door, and vehicle, when the handle 200 is rotated into the operating cavity 110, the rotating component 310 connected to the handle 200 via the transmission assembly also rotates, driving the cable 320 connected to the rotating component 310 to unlock the door lock body, thus achieving mechanical unlocking of the door. Furthermore, the base 100 of this door handle has only one operating cavity 110; the mechanical unlocking component 300 mechanically unlocks the door by rotating the handle 200 inward, making operation convenient and the structure simple. Simultaneously, this door handle is a concealed door handle that does not protrude from the outer surface of the door, reducing wind resistance requirements during vehicle movement.

[0112] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0113] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0114] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
