Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and more specifically to an inward-opening door handle. Background Technology

[0002] The interior door handle is a key component of a car's interior, used to facilitate opening the car door from the inside. Also known as the interior door grab handle, it's a core functional component for passengers operating the door from within the vehicle. Early car door designs primarily used mechanical structures, often connecting the door lock body via a simple lever or cable. The mechanical force of the handle was transmitted to the door lock mechanism through leverage, thus unlocking and opening the door. While this design was simple and inexpensive, it suffered from several drawbacks during use. The handle lacked cushioning, resulting in a stiff feel. Users needed to apply considerable force to open the door, and the operation was prone to noise. Furthermore, when pulled quickly, the lack of a damper could cause the handle to collide with internal door components, producing abnormal noises and potentially damaging the handle or lock body. To address the aforementioned issues, a utility model patent with authorization announcement number CN210343014U discloses a handle, a car door, and a vehicle. The handle includes a handle, an elastic element, a rotating shaft, a base, and a buffer pad. The handle is rotatably connected to the base via the rotating shaft. The elastic element is sleeved on the rotating shaft and connected to both the handle and the base. The buffer pad is fixed to the base at the position where it contacts the handle. The handle has a boss with a roughened structure that contacts the buffer pad. In this technical solution, the return force relies solely on the elastic element. When the handle rebounds, the spring force is released directly, causing a rapid impact with the base, potentially producing a metallic clanging sound. Users experience a noticeable "springy" sensation when releasing the handle, lacking a smooth transition. Furthermore, the lack of speed control during the handle's return process leads to abrupt changes in the force curve when pulling the handle. The opening direction and force of the handle are not ergonomically sound, requiring users to adjust their hand posture, increasing the complexity and inconvenience of operation, and potentially shortening the lifespan of the inward-opening handle. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide an inward-opening door handle, wherein a rotation damper is added between the housing and the inner handle of the handle, and the rotation speed of the inner handle relative to the housing is adjusted by the rotation damper. The damping force provided by the rotation damper makes the rotation of the inner handle buffered, making the feel more comfortable and more in line with the ergonomic design.

[0004] This application provides an inward-opening door handle, including a housing and an inner handle. A handle pin and a reset elastic element are installed between the housing and the inner handle. The inner handle is rotatably mounted on the housing via the handle pin. The reset elastic element is fitted onto the handle pin and abuts against the inner handle. The inner handle is rotated and reset relative to the housing via the reset elastic element. A handle linkage and a rotation damper are installed on the housing. The inner handle is movably connected to the handle linkage. The rotation damper is connected to the handle linkage to provide damping force when the inner handle rotates.

[0005] In this technical solution, the inner handle is rotatable relative to the housing via a handle pin. The inner handle is also reset relative to the housing via a reset elastic element, ensuring that the inner handle automatically returns to its initial position after use. Furthermore, the reset elastic element limits the speed at which the inner handle rotates, making its rotation more reliable and safer, and extending its service life. A handle linkage is provided on the housing, movably connected to the inner handle. This linkage assists in the rotation of the inner handle, preventing excessive rotation angles that could affect its reset. A rotation damper is installed on the handle linkage to adjust the rotation speed between the inner handle and the housing. The lever transmits the rotation of the inner handle to the rotation damper, which provides damping force, making the inner handle operation smoother, reducing the harshness and noise during operation, and improving the user experience. The design of the reset elastic element and the rotation damper helps to reduce the direct impact between the inner handle and the housing, extending the service life of the components. By integrating the rotation damper and the handle linkage into the housing, the entire handle structure is more compact, saving space. By adding a rotation damper to control the rotation speed of the inner handle, accidental injuries caused by rapid rotation of the inner handle can be prevented. This not only improves the operating feel and safety, but also enhances durability and structural compactness.

[0006] As an improvement, both the handle linkage and the rotation damper are located in the middle of the housing. In this technical solution, the handle linkage located in the middle can more effectively transmit the rotation of the inner handle to the rotation damper, achieving more precise control. Placing the rotation damper in the middle of the housing helps to achieve uniform force distribution, reduces excessive stress on individual components, and improves the stability and reliability of the structure. The central layout makes the assembly of the handle linkage and the rotation damper more convenient, simplifies the assembly process, and improves assembly efficiency. On the other hand, it helps to improve the stability of the entire handle structure, reduces structural deformation or damage caused by excessive torque, and thus extends the service life of the components.

[0007] As an improvement, a rotating connector is installed on the inner handle, and the handle linkage has a slotted hole adapted to the rotating connector. The rotating connector is movably connected to the slotted hole. In this technical solution, the rotating connector assists in the relative rotation between the inner handle and the handle linkage, making the rotation smoother and more reliable. By providing a slotted hole on the handle linkage, the rotating connector is allowed to move within the slotted hole. The movable connection design between the rotating connector and the slotted hole allows the inner handle to rotate freely within a certain range, avoiding interference with the rotation of the inner handle while maintaining the connection with the handle linkage. This not only improves the flexibility and comfort of operation but also ensures the stability and reliability of the connection between the inner handle and the handle linkage.

[0008] As an improvement, the inner handle is provided with a first connecting part, and the housing is provided with a second connecting part through which the first connecting part passes. The handle rod is installed on the second connecting part, and the first connecting part passes through the second connecting part and connects to the handle rod. In this technical solution, the inner handle and the housing are connected through the first and second connecting parts, forming a stable rotational fit structure. This ensures the reliability of the inner handle operation, enhances the connection stability between the inner handle and the housing, reduces the risk of failure due to loose connection, and enhances the stability and durability of the structure.

[0009] As an improvement, the first connecting part is provided with a first through hole and a second through hole distributed vertically. The rotating connector passes through the first through hole, the strip hole, and the second through hole in sequence. One end of the rotating connector abuts and limits the movement with the first through hole, and the other end of the rotating connector abuts and limits the movement with the second through hole. In this technical solution, the first connecting part is provided with a first through hole and a second through hole distributed vertically. This design allows the rotating connector to pass through and achieve a limiting function. Setting the rotating connector to pass through the first through hole, the strip hole, and the second through hole in sequence ensures that the rotating connector is in the correct position, realizing the movable connection between the inner handle and the handle linkage. Setting the two ends of the rotating connector to abut and limit the movement with the first through hole and the second through hole respectively prevents the rotating connector from detaching and falling off, ensuring the stability of the connection. Through the cooperation of the first through hole and the second through hole, the assembly process between the inner handle and the handle linkage is simplified, and the assembly efficiency is improved.

[0010] As an improvement, one end of the rotating connector is provided with a limiting seat adapted to the first through hole, and the other end of the rotating connector is provided with a limiting part adapted to the second through hole. The limiting part is provided with an opening groove, and the limiting part is elastic through the opening groove. In this technical solution, the two ends of the rotating connector are respectively provided with a limiting seat and a limiting part. The rotating connector is limited by the limiting seat to abut against the first through hole, and the rotating connector is limited by the limiting part to abut against the second through hole, ensuring the stability and reliability of the connection between the rotating connector and the inner handle. The limiting part is provided with an opening groove, and the design of the opening groove makes the limiting part elastic, which can elastically deform within a certain range to achieve shrinkage and recovery, so that the limiting part can smoothly pass through the first through hole, the strip hole and the second through hole, simplifying the assembly process between the inner handle and the handle connecting rod and improving the assembly efficiency.

[0011] As an improvement, the outer wall of the limiting part is provided with an inclined guide surface, through which the limiting part sequentially passes through the first through hole, the strip hole, and the second through hole. In this technical solution, the addition of an inclined guide surface to the limiting part helps it to pass smoothly through the first through hole, the strip hole, and the second through hole, ensuring the smoothness of the installation process. The limiting part can achieve precise guidance when passing through the through hole, thereby improving assembly efficiency.

[0012] As an improvement, the handle linkage includes an integrally formed linkage seat and linkage shaft. The linkage shaft is connected to the second connecting part, and the strip-shaped hole is provided on the linkage seat. The linkage shaft and the strip-shaped hole are distributed left and right on the linkage seat. In this technical solution, the handle linkage uses an integrally formed linkage seat and linkage shaft, which helps to improve the stability and integrity of the entire handle linkage structure, reduce errors in the assembly process, and the left and right distribution of the linkage shaft and strip-shaped hole on the linkage seat results in a more reasonable spatial distribution and a more compact structure, which is conducive to the transmission of rotational force and makes the use smoother and more comfortable.

[0023] like Figures 1 to 5As shown, this application discloses an inward-opening door handle, including a housing 1 and an inward handle 2. A handle pin 3 and a reset elastic element are installed between the housing 1 and the inward handle 2. The inward handle 2 is rotatably mounted on the housing 1 via the handle pin 3. The reset elastic element is fitted onto the handle pin 3 and abuts against the inward handle 2. The inward handle 2 is rotatably reset relative to the housing 1 via the reset elastic element. The inward handle 2 is rotatable relative to the housing 1 via the handle pin 3. The inward handle 2 is rotatably reset relative to the housing 1 via the reset elastic element, ensuring that the inward handle 2 can automatically return to its initial position after use. On the other hand, the reset elastic element can limit the speed of the inward handle 2's rotation, thereby making the rotation of the inward handle 2 more reliable and safe, and extending the service life of the inward handle 2.

[0024] A handle linkage 4 and a rotation damper 5 are installed on the housing 1. The inner handle 2 is movably connected to the handle linkage 4. The rotation damper 5 is connected to the handle linkage 4 to provide damping force when the inner handle 2 rotates. The handle linkage 4, which is movably connected to the inner handle 2, is provided on the housing 1 to assist the rotation of the inner handle 2 and prevent the inner handle 2 from rotating too much, which would affect its reset. The rotation damper 5 is installed on the handle linkage 4 to adjust the rotation speed of the inner handle 2 and the housing 1. The rotation of the inner handle 2 is transmitted to the rotation damper 5 through the handle linkage 4. The damping force provides smoother operation of the inner handle 2, reducing the harshness and noise during operation and improving the user experience. The design of the reset elastic element and the rotation damper 5 helps to reduce the direct impact between the inner handle 2 and the housing 1, extending the service life of the components. By integrating the rotation damper 5 and the handle linkage 4 into the housing 1, the entire handle structure becomes more compact and saves space. By adding the rotation damper 5 to control the rotation speed of the inner handle 2, accidental injuries caused by the rapid rotation of the inner handle 2 can be prevented. This not only improves the operating feel and safety, but also enhances durability and structural compactness.

[0025] More specifically, such as Figure 1 As shown, both the handle linkage 4 and the rotation damper 5 are located in the middle of the housing 1. The handle linkage 4, located in the middle, can more effectively transmit the rotation of the inner handle 2 to the rotation damper 5, achieving more precise control. Placing the rotation damper 5 in the middle of the housing 1 helps to achieve uniform force distribution, reduces excessive stress on individual components, and improves the stability and reliability of the structure. The central layout makes the assembly of the handle linkage 4 and the rotation damper 5 more convenient, simplifies the assembly process, and improves assembly efficiency. On the other hand, it helps to improve the stability of the entire handle structure, reduces structural deformation or damage caused by excessive torque, and thus extends the service life of the components.

[0026] More specifically, such as Figure 1As shown, a rotating connector 6 is installed on the inner handle 2, and a strip hole 41 adapted to the rotating connector 6 is provided on the handle link 4. The rotating connector 6 is movably connected to the strip hole 41. The rotating connector 6 assists in the relative rotation between the inner handle 2 and the handle link 4, making the rotation smoother and more reliable. By providing a strip hole 41 on the handle link 4, the rotating connector 6 is allowed to move within the strip hole 41. The movable connection design between the rotating connector 6 and the strip hole 41 allows the inner handle 2 to rotate freely within a certain range, avoiding interference with the rotation of the inner handle 2, while maintaining the connection with the handle link 4. This not only improves the flexibility and comfort of operation, but also ensures the stability and reliability of the connection between the inner handle 2 and the handle link 4.

[0027] More specifically, such as Figures 1 to 3 As shown, the inner handle 2 is provided with a first connecting part 21, and the housing 1 is provided with a second connecting part 11 through which the first connecting part 21 passes. The handle rod 4 is installed on the second connecting part 11. The first connecting part 21 passes through the second connecting part 11 and is connected to the handle rod 4. The inner handle 2 and the housing 1 are connected through the first connecting part 21 and the second connecting part 11, forming a stable rotational fit structure. This ensures the reliability of the operation of the inner handle 2, enhances the connection stability between the inner handle 2 and the housing 1, reduces the risk of failure due to loose connection, and enhances the stability and durability of the structure.

[0028] More specifically, such as Figures 1 to 3 As shown, the first connecting part 21 is provided with a first through hole 211 and a second through hole 212 distributed vertically. The rotating connector 6 passes through the first through hole 211, the strip hole 41, and the second through hole 212 in sequence. One end of the rotating connector 6 abuts against and is limited by the first through hole 211, and the other end of the rotating connector 6 abuts against and is limited by the second through hole 212. The first connecting part 21 is provided with a first through hole 211 and a second through hole 212 distributed vertically. This design allows the rotating connector 6 to pass through and achieves the limiting function. The connector 6 passes through the first through hole 211, the strip hole 41, and the second through hole 212 in sequence to ensure that the rotating connector 6 is in the correct position, thereby realizing the movable connection between the inner handle 2 and the handle linkage 4. The two ends of the rotating connector 6 are respectively set to abut and limit the first through hole 211 and the second through hole 212 to prevent the rotating connector 6 from falling off and to ensure the stability of the connection. Through the cooperation of the first through hole 211 and the second through hole 212, the assembly process between the inner handle 2 and the handle linkage 4 is simplified and the assembly efficiency is improved.

[0029] More specifically, such as Figure 1 , Figure 2 and Figure 5As shown, one end of the rotating connector 6 is provided with a limiting seat 61 adapted to the first through hole 211, and the other end of the rotating connector 6 is provided with a limiting part 62 adapted to the second through hole 212. The limiting part 62 is provided with an opening groove 63, which allows the limiting part 62 to be elastic. The two ends of the rotating connector 6 are respectively provided with a limiting seat 61 and a limiting part 62. The rotating connector 6 is limited by the limiting seat 61 to abut against the first through hole 211, and the rotating connector 6 is limited by the limiting part 62 to abut against the first through hole 211. The second through hole 212 abuts against the limit, ensuring the stability and reliability of the connection between the rotating connector 6 and the inner handle 2. The limit part 62 is provided with an opening groove 63. The design of the opening groove 63 makes the limit part 62 elastic, which can elastically deform within a certain range to achieve shrinkage and recovery. This allows the limit part 62 to pass smoothly through the first through hole 211, the strip hole 41 and the second through hole 212, simplifying the assembly process between the inner handle 2 and the handle connecting rod 4 and improving the assembly efficiency.

[0030] More specifically, such as Figure 5 As shown, the outer wall of the limiting part 62 is provided with an inclined guide surface 621. The limiting part 62 passes through the first through hole 211, the strip hole 41 and the second through hole 212 in sequence through the inclined guide surface 621. The addition of the inclined guide surface 621 to the limiting part 62 helps the limiting part 62 to pass through the first through hole 211, the strip hole 41 and the second through hole 212 smoothly, ensuring the smoothness of the installation process. The limiting part 62 can achieve precise guidance when passing through the through hole, thereby improving the assembly efficiency.

[0031] More specifically, such as Figure 1 and Figure 4 As shown, the handle link 4 includes an integrally formed link seat 42 and a link shaft 43. The link shaft 43 is connected to the second connecting part 11. A strip hole 41 is provided on the link seat 42. The link shaft 43 and the strip hole 41 are distributed on the link seat 42 from left to right. The use of an integrally formed link seat 42 and link shaft 43 in the handle link 4 helps to improve the stability and integrity of the entire handle link 4 structure and reduce errors in the assembly process. The arrangement of the link shaft 43 and the strip hole 41 on the link seat 42 from left to right results in a more reasonable spatial distribution and a more compact structure, which is conducive to the transmission of rotational force and makes the use smoother and more comfortable.

[0032] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
