Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a delayed-closing door handle and its operating method. Background Technology

[0002] Hidden car door handles are automotive components that are flush with the door when closed and protrude from the outer surface of the door when open. They reduce wind resistance and enhance the sense of technology. Compared to traditional pull-type door handles, hidden door handles are more aesthetically pleasing, simpler, and provide a better user experience.

[0003] Most concealed door handles on the market are electrically driven. If the internal wiring is faulty or loose, it can easily cause the handle to malfunction in opening or closing. While existing manually operated concealed door handles can be forced to open by pressing one end, protruding from the door, they are constantly under the influence of a return spring while in the raised position, tending to close. Users need to hold the handle continuously to prevent it from automatically returning to its original position. This can be inconvenient, especially when carrying other items or quickly entering or exiting the vehicle. Furthermore, when automatically returning to its original position, this type of door handle may quickly retract and interfere with or collide with other components within the handle base, generating noise.

[0004] Another type of concealed handle in the prior art can hover in the open state for a certain period of time, but it returns to its original position too quickly after the hovering time ends, which can easily cause interference and collision with other components in the handle base, generating noise. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a delayed closing door handle.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a delayed-closing car door handle.

[0007] The base is used to house the handle body;

[0008] The handle body has a closed position flush with the door and an open position outside the door. A transmission pin is also provided on one side of the handle body to move with the handle body.

[0009] A control arm connected to an unlocking component, wherein the handle body moves closer to and actuates the control arm during the opening action;

[0010] The damping assembly includes a damping element and a transmission element disposed on a base. The transmission pin moves within the transmission element and actuates the transmission element to rotate with the movement of the handle body. The damping element applies a force that resists the action of the transmission element.

[0011] The transmission member is provided with a blocking edge located on one side of the transmission pin return direction. The blocking edge has at least a ready position corresponding to the closed position of the handle body and a return obstruction stroke corresponding to the handle body from the open position to the closed position as the transmission member rotates. In the ready position, the blocking edge enters the return trajectory of the transmission pin, and the blocking edge is actuated in the return obstruction stroke to gradually return to the ready position.

[0012] Furthermore, the conductive member is also provided with an actuating edge spaced apart from the blocking edge. The actuating edge is located in the opening trajectory of the transmission pin. The transmission pin presses against the actuating edge as the handle body is opened, so as to make the conductive member rotate.

[0013] Furthermore, the conductive member has an outwardly extending groove, and the blocking edge is connected to the end of the groove to form a blocking part. The blocking part abuts against the transmission pin during the return stroke, and the blocking part gradually moves away from the return trajectory of the transmission pin.

[0014] Furthermore, the blocking edge also has an opening guide stroke corresponding to the handle body from the closed position to the open position. The transmission pin passes through the blocking edge and abuts against the actuating edge during the opening guide stroke. After the handle body moves to the open position, the transmission pin abuts against the receiving groove and remains abutting against the blocking part during the return blocking stroke.

[0015] Furthermore, the transmission pin slides on the actuation side as the handle body unlocks, and returns to the receiving groove as the handle body returns to its original position.

[0016] Furthermore, the blocking edge is also configured with a rapid return stroke between the return obstruction stroke and the ready position. During the rapid return stroke, the blocking edge leaves the return trajectory of the transmission pin or coincides with the boundary of the return trajectory of the transmission pin, so as to allow the transmission pin to return quickly.

[0017] Furthermore, the base is also provided with a mounting seat, the conductive element is inserted into the mounting seat and rotates, and the damping element is provided on the mounting seat. A positioning block with plug-in engagement is provided between the mounting seat and the base.

[0018] Furthermore, the radial protrusion of the conductive member has a limiting block, which limits the axial position of the conductive member within the mounting base. The end face of the mounting base is provided with a mating groove that matches the limiting block. The mating groove communicates with the inner cavity of the mounting base and is located outside the movement trajectory of the limiting block.

[0019] Furthermore, bearings are provided at both ends of the corresponding conductive element within the mounting base.

[0020] Furthermore, the damping member has a transmission part at its end, and the transmission member has a transmission groove that matches the transmission part.

[0021] A method for operating a delayed-closing car door handle, for use with the aforementioned delayed-closing car door handle, includes the following steps:

[0022] A. Assemble the damping components, set up the mounting base and place the transmission component inside the mounting base, fix the damping component on the top of the mounting base and cooperate with the transmission component, then fix the mounting base to the base after positioning and fixing it. Adjust the position of the transmission pin or the position of the transmission component by adjusting the handle body to fit the transmission pin into the transmission component.

[0023] B. Open the handle body, press one end of the handle body in the closed position to force the handle body to rotate to the open position, and the transmission pin will push the transmission component to rotate as the handle body moves, and the blocking edge will enter the return trajectory of the transmission pin. Then release the handle body.

[0024] C. The handle body returns to its original position after a delay. Under the action of its own torsion spring, the handle body begins to reset. The transmission pin actuates the transmission component again, and the blocking edge resists the transmission pin in real time, forcing the transmission pin to overcome the force of the damping component. The blocking edge tends to be tangent to the return trajectory of the transmission pin as the transmission pin moves, and eventually leaves the return trajectory of the transmission pin.

[0025] D. Return the handle body to its original position. When the blocking edge is about to return to the ready position, the handle body and the transmission pin will quickly return to their original positions under the action of the torsion spring.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects: By setting a transmission pin parallel to the rotation axis of the handle body and a transmission component connected to the damping component on the handle body, during the normal opening of the handle body, the transmission component is pushed and rotated by the transmission pin, and at the same time the blocking edge rotates synchronously and enters the return trajectory of the transmission pin. This means that during the process of the handle body moving from the open position to the closed position, the handle body needs to overcome the resistance from the transmission pin and the blocking edge, and the transmission component and the damping component, thereby achieving the slow return of the handle body. During the return process, the transmission pin actuates the transmission component again, forcing the blocking edge to rotate in the opposite direction, thereby causing the blocking edge to gradually move away from the return trajectory of the transmission pin. Finally, the transmission pin pushes open the blocking edge and returns to the position quickly.

[0027] The present invention effectively reduces the abnormal noise of the handle body during the slow return movement and avoids interference with other components in the base. When the handle body is ready to return quickly, it has already rotated an angle through the slow return movement, thereby reducing the rapid reset stroke of the handle body and avoiding noise caused by the excessively fast return speed of the handle body. At the same time, the return speed of the handle body and the time of the slow movement can be adjusted by replacing the damping component.

[0028] In addition, during the opening and unlocking process, users need to manually pull the handle and overcome the resistance from the damping components to improve the operating feel. Attached Figure Description

[0042] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0044] like Figure 1-12 As shown, a delayed-closing door handle,

[0045] The base 1 is fixedly installed on the inside of the door to accommodate the handle body 2. The base 1 is provided with a slot for the handle body 2 to pass through.

[0046] The handle body 2 has a closed position flush with the door, an open position outside the door, and an unlocked position that continues to move in the opening direction relative to the open position. The handle body 2 has a pivot 2.2, and the handle body 2 rotates around the pivot 2.2 between the closed position, the open position, and the unlocked position. A torsion spring 8 is also provided on the pivot 2.2. The fixed end of the torsion spring 8 abuts against the base 1, and the free end of the torsion spring 8 abuts against the handle body 2, thereby applying a force to move the handle body 2 from the unlocked position or from the open position towards the closed position.

[0047] A transmission pin 2.1 is located on one side of the handle body 2 and moves synchronously with the handle body 2. The transmission pin 2.1 is also arranged parallel to the rotating shaft 2.2 of the handle body 2.

[0048] Control arm 3 is connected to the unlocking component. The handle body 2 approaches and actuates the control arm 3 during the opening action. In the open position, the handle body 2 approaches or contacts the control arm 3. The handle body 2 is further actuated by the hand in the open position to actuate the control arm 3, thereby unlocking the car door.

[0049] like Figure 3 As shown, the damping assembly includes a damping element 4 and a transmission element 5 disposed on the base 1. The transmission pin 2.1 is constrained to move within the opening of the transmission element 5 and actuates the transmission element 5 to rotate with the movement of the handle body 2. The damping element 4 always applies a force that resists the action of the transmission element 5. Especially during the return movement of the handle body 2, the transmission pin 2.1 actuates the transmission element 5 and simultaneously overcomes the force from the damping element 4, thereby slowing down the return movement of the handle body 2.

[0050] The transmission member 5 is provided with a blocking edge 5.1 located on the side of the return direction of the transmission pin 2.1. The blocking edge 5.1 has at least a ready position corresponding to the closed position of the handle body 2 and a return resistance stroke corresponding to the return position of the handle body 2 from the open position to the closed position as the transmission member 5 rotates. In the ready position, the blocking edge 5.1 enters the return trajectory of the transmission pin 2.1, and the blocking edge 5.1 is actuated by the transmission pin 2.1 during the return resistance stroke and gradually returns to the ready position. The blocking edge 5.1 follows the transmission pin 2.1 to gradually return to the ready position, and when the blocking edge 5.1 returns to or is about to return to the ready position, the transmission pin 2.1 overcomes the resistance and enables the handle body 2 to return quickly.

[0051] from Figures 4 to 7 As shown, in one embodiment where the transmission pin 2.1 actuates the transmission member 5 during the opening of the handle body 2, the transmission member 5 is also provided with an actuating edge 5.2 spaced apart from the blocking edge 5.1. The actuating edge 5.2 is specifically located on the side of the blocking edge 5.1 closer to the opening direction, and the actuating edge 5.2 is located in the opening trajectory of the transmission pin 2.1, so as to ensure that the transmission pin 2.1 presses against the actuating edge 5.2 as the handle body 2 opens, so as to make the transmission member 5 rotate.

[0052] like Figure 6 As shown, in the open position, the transmission pin 2.1 abuts against the actuating edge 5.2. As the user pulls the handle body 2 further, the transmission pin 2.1 abuts against the actuating edge 5.2, thereby driving the transmission component 5 to rotate. At this time, the transmission pin 2.1 slides on the actuating edge 5.2. With the help of the resistance from the damping component 4 and the restriction of the actuating edge 5.2, it guides the unlocking action of the handle body 2 and increases the user's unlocking feel.

[0053] from Figure 4 As can be seen, as a further embodiment of the transmission member 5, the transmission member 5 is provided with a receiving groove 5.3 extending radially outward from its rotation center. The receiving groove 5.3 matches the contour of the transmission pin 2.1 so that the transmission pin 2.1 can be inserted into the receiving groove 5.3 as the handle body 2 moves. The two ends of the receiving groove 5.3 are respectively connected to the actuating edge 5.2 and the blocking edge 5.1, so that the transmission member 5 has a roughly V-shaped cross section.

[0054] Specifically, the groove 5.3 corresponds to the extension 5.12 of the blocking edge 5.1, which is parallel to the actuating edge 5.2. In the open position, the transmission pin 2.1 can abut against the extension 5.12, thereby driving the transmission member 5 to start performing the return action.

[0055] As a further embodiment of the blocking edge 5.1, the blocking edge 5.1 is connected to the end of the receiving groove 5.3, and the blocking edge 5.1 is inclined about the extending direction of the receiving groove 5.3 and the actuating edge 5.2, and forms an outwardly expanding angle at the end of the receiving groove 5.3. This arrangement allows the blocking edge 5.1 to gradually leave the return trajectory of the transmission pin 2.1 during the return operation of the transmission member 5, thereby allowing the transmission pin 2.1 to gradually return, and to quickly return after the blocking edge 5.1 leaves the return trajectory.

[0056] Specifically, the blocking edge 5.1 is connected to the aforementioned extension 5.12 so that the blocking edge 5.1 and the center of the conductor 5 maintain a certain distance, so as to ensure that the transmission pin 2.1 can smoothly drive the conductor 5.

[0057] Specifically, the blocking edge 5.1 is bent at the end of the receiving groove 5.3 to form the blocking part 5.11, or the blocking edge 5.1 is bent at the end of the extension section 5.12 to form the blocking part 5.11. The blocking part 5.11 abuts against the transmission pin 2.1 during the return blocking stroke, and the transmission pin 2.1 can still overcome the damping force and the blocking force of the transmission member 5 under the action of the torsion spring 8, so that the blocking part 5.11 gradually moves away from the return trajectory of the transmission pin 2.1, thereby performing the slow reset action of the handle body 2.

[0058] like Figure 8 As shown in the figure, the dashed line represents the return trajectory of the transmission pin 2.1, and the solid line represents the blocking edge 5.1. Preferably, the blocking part 5.11 is set with an arc contour. During the process of the transmission pin 2.1 moving from the open position to the closed position, the transmission pin 2.1 travels from one end of the blocking part 5.11 near the rotation center of the conductor 5 towards the other end of the blocking part 5.11. Of course, during this process, the conductor 5 and its blocking part 5.11 and blocking edge 5.1 are actuated by the transmission pin 2.1 and rotated. In this way, the smoothness of the relative sliding of the transmission pin 2.1 on the conductor 5 is improved, and the jamming of the handle body 2 during the slow return process is reduced.

[0059] Specifically, the blocking edge 5.1 also has an opening guide stroke corresponding to the handle body 2 from the closed position to the open position.

[0060] like Figure 4 As shown, when the handle body 2 is in the closed position, the transmission pin 2.1 is in the ready position on the blocking edge 5.1, and the blocking edge 5.1 is far away from the movement trajectory of the transmission pin 2.1.

[0061] like Figure 5As shown, when the handle body 2 moves toward the open position, the transmission pin 2.1 passes over the blocking part 5.11 from the blocking edge 5.1 during the opening guide stroke and abuts against the actuating edge 5.2. After the handle body 2 moves to the open position, the transmission pin 2.1 abuts against the receiving groove 5.3. At this time, the transmission pin 2.1 is closer to the rotation center of the transmission member 5 than the closed position and abuts against the end of the blocking part 5.11 away from the blocking edge 5.1. Both the blocking part 5.11 and the blocking edge 5.1 enter the return trajectory of the transmission pin 2.1.

[0062] During the opening process of the handle body 2, the transmission pin 2.1 does not directly drive the blocking edge 5.1, but slides on the blocking edge 5.1 until the transmission pin 2.1 abuts against the actuating edge 5.2. Optionally, the blocking edge 5.1 can be set to match the trajectory of the transmission pin 2.1 from the closed position to the open position of the handle body 2, thereby playing a certain guiding role in the opening and returning actions of the handle body 2.

[0063] Reference Figures 4 to 7 The dotted line in the figure represents the return trajectory of the transmission pin 2.1. When the handle body 2 moves from the open position to the closed position, the transmission pin 2.1 returns to its original position under the action of the torsion spring 8. During the return resistance stroke, the transmission pin 2.1 abuts against the blocking part 5.11 and prepares to pass over the blocking part 5.11 as the transmission member 5 is passively rotated. The blocking part 5.11 and the blocking edge 5.1 gradually move away from the return trajectory of the transmission pin 2.1. During this process, the handle body 2 performs a slow reset action. When the blocking part 5.11 leaves or is about to leave the return trajectory of the transmission pin 2.1, the transmission pin 2.1 and the handle body 2 quickly return to their original positions under the action of the torsion spring 8.

[0064] Specifically, the blocking edge 5.1 is also equipped with a rapid return stroke between the return blocking stroke and the ready position. During the rapid return stroke, the blocking edge 5.1 leaves the return trajectory of the transmission pin 2.1 or coincides with the boundary of the return trajectory of the transmission pin 2.1, so as to allow the transmission pin 2.1 to return quickly.

[0065] In other embodiments, the transmission pin 2.1 is prepared to return quickly after passing the blocking part 5.11, while the blocking edge 5.1 is still partially located in the return trajectory of the transmission pin 2.1, so as to avoid the handle body 2 returning too quickly with the help of the damping member 4.

[0066] As a further explanation of the slow return of the handle body 2, as the handle body 2 returns to its original position, the blocking part 5.11 and the blocking edge 5.1 are actuated by the transmission pin 2.1 and gradually move away from the return trajectory of the transmission pin 2.1. The blocking edge 5.1 gradually tends to be parallel to or fit against the boundary of the return trajectory of the transmission pin 2.1, so that the transmission pin 2.1 is freed from the obstruction and allows the transmission pin 2.1 to return to its original position quickly under the action of the torsion spring 8.

[0067] Specifically, during the slow return of the handle body 2, the obstructing force exerted by the blocking part 5.11 on the transmission pin 2.1 gradually decreases. The blocking part 5.11 and the blocking edge 5.1 are inclined into the return trajectory of the transmission pin 2.1 to facilitate the transmission pin 2.1 to apply an effective force to the transmission member 5, thereby actuating the transmission member 5. The mating position of the transmission pin 2.1 and the blocking part 5.11 always faces the side of the return direction. The angle formed by the blocking part 5.11, the blocking edge 5.1 and the return trajectory of the transmission pin 2.1 gradually decreases with the return action.

[0068] Reference Figure 8 Furthermore, the damping component 4 and the transmission component 5 are concentrically arranged. Figure 8 The dashed circle in the middle indicates the center position of the damping component. When the transmission pin 2.1 rotates from the open position of the handle body to the closed position, the distance L between the center of the transmission pin 2.1 and the center of the damping component 4 and the transmission component 5 gradually increases. This causes the lever arm between the transmission pin 2.1 and the damping component to gradually increase. Under the condition that the blocking part 5.11 and the blocking edge 5.1 gradually leave the return trajectory of the transmission pin 2.1, the transmission pin 2.1 is guided to be released along its return trajectory, so that the return speed of the transmission pin 2.1 in the return resistance stroke gradually increases. That is, the handle body 2 and the transmission pin 2.1 gradually tend to perform a rapid return action, ensuring that the handle body 2 returns to the closed position.

[0069] It is worth mentioning that the handle body 2 has rotated by an angle after the slow return action ends, thereby reducing the stroke of the rapid return, effectively reducing noise and collision sounds, and avoiding interference with other components in the base. Of course, the angle of the slow return can also be controlled by adjusting the contour of the blocking part and the relative position between the blocking part and the transmission pin, thereby further optimizing the noise reduction effect.

[0070] like Figure 7 As shown, specifically, the transmission pin 2.1 slides on the actuating edge 5.2 as the handle body 2 unlocks, and returns to the receiving groove 5.3 as the handle body 2 returns. During this process, the transmission pin 2.1 moves away from the blocking part 5.11, providing the user with a feel by overcoming the force of the torsion spring 8 and the damping element 4 of the handle body 2.

[0071] like Figure 9 and Figure 10 As shown, in some other embodiments, to improve the ease of assembly of the damping components, the base 1 is also provided with a mounting seat 6. The mounting seat 6 is used to provide an installation position for the damping component 4 and the transmission component 5. Preferably, the mounting seat 6 is located on the side of the base 1 that extends axially about the pivot 2.2 of the handle body 2. Furthermore, the mounting seat 6 can also be located away from the rotation center of the control arm 3 to avoid interference with the control arm 3.

[0072] from Figure 10 As can be seen, specifically, the transmission element 5 has a main shaft 5.6 that rotates within the mounting base 6. The blocking edge 5.1 and the actuating edge 5.2 are both located at the bottom of the main shaft 5.6 and extend beyond it, being inserted into the mounting base 6. The main shaft 5.6 of the transmission element 5 is inserted from the lower end of the mounting base 6, and the damping element 4 fixes the mounting base 6 to the other end of the mounting base 6. The mounting base 6 is fixed to the base 1 by screws. (Refer to...) Figure 11 In the middle, a positioning block 6.1 is provided between the mounting base 6 and the base 1 for plug-in engagement. The positioning block 6.1 is set perpendicular to the rotating shaft 2.2 of the transmission component 5, so that the mounting base 6 can be pre-positioned on the base 1 by the positioning block 6.1, which facilitates installation. The damping component is modularly installed on the base 1 by the mounting base 6, which is convenient to operate and improves assembly efficiency.

[0073] Based on the modular installation of the damping components, it is more convenient to replace the damping component 4 or adjust the damping force of the damping component 4.

[0074] like Figure 10 As shown, in a further embodiment of the cooperation between the transmission element 5 and the mounting base 6, the radial protrusion of the transmission element 5 is a limiting block 5.4. The limiting block 5.4 restricts the axial position of the transmission element 5 within the mounting base 6. The end face of the mounting base 6 is provided with a mating groove 6.2 that matches the limiting block 5.4. The mating groove 6.2 communicates with the inner cavity of the mounting base 6. After the main shaft 5.6 of the transmission element 5 is inserted into the mounting base 6, the transmission element 5 is rotated, and the mating groove 6.2 is located outside the movement trajectory of the limiting block 5.4.

[0075] like Figure 12 As shown, in some other embodiments, bearings 7 are provided at both ends of the mounting base 6 corresponding to the transmission member 5, and the transmission member 5 and the inner ring of the bearing 7 are interference-fitted to improve the reliability and stability of the rotation of the transmission member 5.

[0076] Of course, based on the setting of the limiting block 5.4 on the transmission component 5, bearings 7 can be further set at both ends of the transmission component 5.

[0077] As one embodiment of the damping component 4, the damping component 4 is preferably fixed to the upper end of the mounting base 6 by bolts, and the end of the damping component 4 is provided with a transmission part 4.1. The transmission part 5 is provided with a transmission groove 5.5 that matches the transmission part 4.1. The transmission part 4.1 is coaxially arranged with the transmission part 5. The transmission part 4.1 extends into the mounting base 6 and is in transmission cooperation with the transmission groove 5.5.

[0078] like Figure 10As shown, optionally, the transmission part 4.1 of the damping component 4 can be a damping gear. The transmission groove 5.5 is engaged with the gear part of the damping gear. By replacing the damping gear of the damping component 4, the damping force on the transmission component 5 can be adjusted, thereby controlling the speed at which the transmission pin 2.1 and the handle body 2 slowly return to their original positions.

[0079] like Figure 11 As shown, alternatively, the transmission part 4.1 of the damping element 4 can also be of other shapes, such as a straight line, and the transmission between the damping element 4 and the transmission element 5 can be achieved simply by docking with the transmission groove 5.5.

[0080] As another way to adjust the damping force of the damping component 4, the above-mentioned speed of slow return of the handle body 2 can also be achieved by directly replacing the damping component 4 with a different damping force.

[0081] Furthermore, a buffer pad 9 is fixed on the base 1. The buffer pad 9 corresponds to the end of the handle body 2 away from its pivot 2.2, so as to further reduce the abnormal noise when the handle body 2 returns to its original position.

[0082] A method for operating a delayed-closing car door handle, for use with the aforementioned delayed-closing car door handle, includes the following steps:

[0083] A. Assemble the damping components, set the mounting base 6 and place the transmission component 5 into the mounting base 6, fix the damping component 4 on the top of the mounting base 6 and cooperate with the transmission component 5, then fix the mounting base 6 to the inside of the base 1 after positioning, and adjust the position of the transmission pin 2.1 or the position of the transmission component 5 by adjusting the handle body 2 to fit the transmission pin 2.1 into the transmission component 5.

[0084] B. Open the handle body 2, press one end of the handle body 2 in the closed position to force the handle body 2 to rotate to the open position, and the transmission pin 2.1 pushes the transmission component 5 to rotate as the handle body 2 moves, and the blocking edge 5.1 enters the return trajectory of the transmission pin 2.1, and then release the handle body 2;

[0085] C. The handle body 2 returns to its original position after a delay. Under the action of its own torsion spring 8, the handle body 2 begins to reset. The transmission pin 2.1 actuates the transmission element 5 again, and the blocking edge 5.1 blocks the transmission pin 2.1 in real time, forcing the transmission pin 2.1 to overcome the force of the damping element 4. The blocking edge 5.1 tends to be tangent to the return trajectory of the transmission pin 2.1 as the transmission pin 2.1 moves, and eventually leaves the return trajectory of the transmission pin 2.1.

[0086] D. When the handle body 2 is about to return to the ready position, the handle body 2 and the transmission pin 2.1 are quickly returned to their original positions under the action of the torsion spring 8.

[0087] In step A, after aligning the limiting block 5.4 of the transmission component 5 with the mating groove 6.2 on the mounting base 6, the main shaft 5.6 is placed into the mounting base 6. Then, the transmission component 5 is rotated, and the damping component 4 is fixed at the upper end of the mounting base 6. The damping component 4 is then adjusted to align with the transmission groove 5.5 of the transmission component 5. Finally, the positioning block 6.1 on the mounting base 6 is aligned with the positioning groove 1.1 on the base 1. The mounting base 6 is then fixed with bolts. After completing the modular installation of the damping assembly, the actuating edge 5.2 and the blocking edge 5.1 are adjusted to one side of the transmission pin 2.1.

[0088] The two sides of the positioning groove 1.1 are holes for fixing the mounting base 6 to the base 1.

[0089] In step B, the transmission pin 2.1 actuates the actuating edge 5.2 of the transmission member 5 and is placed in the receiving groove 5.3, and the end of the transmission pin 2.1 close to the blocking part 5.11 corresponds to the rotation center of the transmission member 5.

[0090] After step B, the unlocking step of handle body 2 is also included. Handle body 2 is manually pulled and driven to rotate further in the opening direction. At this time, transmission pin 2.1 moves and slides against the actuation edge, and transmission member 5 continues to rotate at an angle.

[0091] In step C, the transmission pin 2.1 abuts against the blocking part 5.11 under the action of the torsion spring 8, thereby actuating the transmission member 5 to rotate in the opposite direction. The transmission pin 2.1 moves along the blocking part 5.11 along its own return trajectory and the passive rotation of the blocking edge 5.1 until the transmission pin 2.1 is ready to pass the blocking part 5.11. During this process, the handle body 2 slowly returns to its original position.

[0092] In step D, the transmission pin 2.1 slides along the blocking edge 5.1 and moves away from the blocking part 5.11.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
