Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a suspended parking 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] Currently, more and more car brands are adopting hidden exterior door handles, which generally use electronic or electric mechanisms. When a passenger presses the handle, the door lock will automatically unlock and pop out a short distance, allowing the user to insert their fingers into the handle to open the door. When the passenger finishes the operation and releases the handle, the door handle will retract and lock again.

[0004] Since the aforementioned concealed handles are electrically or electronically controlled, if the vehicle battery is low on power or malfunctions, the handles may not function properly. Furthermore, these concealed handles require the connection of multiple sensors to determine the position of the handle body and the position of the main internal drive components, resulting in a complex internal structure and high cost.

[0005] Existing technologies, such as swing-out retractable handles and flat-out retractable handles, can force the handle body to tilt up by pressing one end of the handle body, thus protruding from the door handle for emergency use. However, when such a handle is tilted up, it is always subject to the return torsion spring of the handle body, tending to close. Users need to always hold the tilted handle body when using it, which is inconvenient. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a suspended parking door handle.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a suspended parking door handle, comprising:

[0008] The base is used to house the handle body;

[0009] The handle body has a closed position flush with the door and an open position outside the door. The handle body also has a protruding transmission seat placed in the base, and the transmission seat moves synchronously with the handle body.

[0010] A control arm is connected to an unlocking component, and the transmission seat actuates the control arm as the handle body is opened;

[0011] The hovering assembly includes a stop bar mounted on a base, a blocking portion mounted on a transmission seat, and a spring abutting against the stop bar. The spring applies a force to the stop bar abutting against the transmission seat. During the trajectory of the handle body from the open position to the closed position, the stop bar engages with the blocking portion and prevents the handle body from rotating, thereby maintaining the handle body in a hovering position away from the open position. The stop bar is actuated by an external force to move away from the blocking portion, thereby allowing the handle body to return to the closed position.

[0012] The reset component is indirectly actuated by the opening action of the handle body, and gradually returns to its original position when the handle body is in the open position, and gradually applies a force to the stop bar away from the blocking part.

[0013] Furthermore, the reset assembly also includes a cam disk and a first torsion spring acting on the cam disk. When the handle body is in the closed position, the cam disk is rotated directly or indirectly by actuation through a transmission seat, and the cam disk is provided with a ramp. The stop lever has a first guide portion disposed opposite to the ramp. When the handle body is in the open position, the ramp guides the stop lever away from the blocking portion by rotation.

[0014] Furthermore, the base is also provided with a damping assembly connecting the cam disk and the transmission seat. The damping assembly includes a transmission component and a damping gear fixed on the cam disk. The transmission component is provided with a gear part, and the damping gear meshes with the gear part. The transmission component is actuated by the opening action of the transmission seat and drives the cam disk to rotate through the gear part. Moreover, the engagement between the damping assembly and the cam disk always applies a force that resists the return of the cam disk.

[0015] Furthermore, the base is also provided with a transmission component, which includes a transmission part. A second torsion spring is engaged between the transmission component and the base. The second torsion spring applies a force to the transmission component to actuate the handle body toward the closed position. In the closed position, the transmission part is placed inside the transmission seat and prevents the transmission seat from moving. The handle body is manually moved to the open position and the transmission part is actuated to the open position by the transmission seat. The transmission component is engaged with the outer wall of the transmission seat, and the stop bar stops the transmission seat to prevent the transmission component from rotating.

[0016] Furthermore, the transmission component also includes a gear section, and a damping gear is provided on the cam disk, the damping gear meshing with the gear section.

[0017] Furthermore, the handle body has a rotating shaft A, the cam disc is coaxially arranged with the transmission component, and has a rotating shaft B parallel to the rotating shaft A, and the hovering component is arranged between the rotating shaft A and the rotating shaft B.

[0018] Furthermore, a stop block is detachably embedded on the transmission seat, and the blocking part is formed on the stop block; the stop block is provided with a first slide rail and a second slide rail corresponding to the front and rear parts of the blocking part, the first slide rail allows the stop rod to move between the open position and the hovering position, and the second slide rail allows the stop rod to move between the hovering position and the closed position.

[0019] Furthermore, the transmission part is located near the free end of the torsion spring, and the transmission member is provided with a first arc portion that is convex on one side of the transmission part. The first arc portion abuts against the inner wall of the transmission seat when in the closed position. The transmission member is provided with a second arc portion that is concave on the other side of the transmission part. The second arc portion is located near the rotation center of the transmission member.

[0020] Furthermore, the transmission seat is provided with an actuating part, which has an actuating surface disposed on the inner wall of the transmission seat and a mating surface disposed on the outer wall of the transmission seat. In the closed position, the actuating part abuts against the transmission part. In the closed position, the actuating surface abuts against the transmission part and faces the second arc portion. In the open position, the mating surface fits against the second arc portion.

[0021] In the closed position, the direction of the force exerted by the transmission unit on the actuating surface tends to be perpendicular;

[0022] In the open position, the direction of the force exerted by the transmission unit on the actuating surface is close to the rotation center of the handle body.

[0023] Furthermore, the stop bar is provided with a second guide portion for engaging with the blocking part, the second guide portion slidingly engaging with the stop block, and the blocking part being a step protruding from the stop block.

[0024] A method for operating a suspended parking door handle, applied to the aforementioned suspended parking door handle, includes the following steps:

[0025] A. 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 stop lever is engaged with the transmission seat in a pressing posture. At the same time, the transmission component, damping gear and cam plate are actuated, so that the first guide part enters the starting section of the ramp, and the transmission component leaves the transmission seat and engages with the outer wall of the transmission seat.

[0026] B. Hover the handle body and keep the stop lever in a pressing position to engage with the blocking part. At this time, the cam plate rotates in the opposite direction by the first torsion spring, and the first guide part gradually follows the movement along the ramp until the stop lever is guided to gradually move away from the blocking part.

[0027] C. The handle returns to its original position, the first guide part enters the end section of the ramp, at this time the stop bar is completely away from the blocking part, the handle returns to its original position under the reset force, the blocking part passes the stop bar as the handle returns to its original position, and the transmission component is placed in the transmission seat.

[0028] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0029] 1. In this invention, by setting a stop bar and a blocking part on the transmission seat of the handle body, during the normal opening process of the handle body, pressing one end of the handle body forces the handle body to move out of the car door and into the open position. After the handle is released, the stop bar can engage with the blocking part on the transmission seat, thereby preventing the handle body from returning to its original position and achieving the suspension of the handle body.

[0030] 2. By setting a reset component on one side of the transmission seat, the reset component can leave the free position as the handle body rotates. In the process of resetting the reset component, a force away from the blocking part can be applied to the stop lever. When the stop lever is completely away from the blocking part, the handle body can be reset to the closed position, thereby realizing that the handle body automatically resets to the closed position after being opened and hovered for a certain period of time.

[0031] 3. A damping component is installed between the reset component and the transmission seat of the handle body. The damping component can rotate during the opening action of the handle body and drive the cam plate to rotate to a position to guide the stop lever away from the blocking part. As the handle body is released in the open position, the cam plate reduces the rotation speed under the resistance of the damping component, thereby slowly guiding the stop lever away from the blocking part, thus realizing the control of the hovering time.

[0053] 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.

[0054] 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.

[0055] like Figure 1-12 As shown, a suspended parking door handle includes:

[0056] Base 1, fixed to the inner surface of the door, and used to accommodate handle body 2;

[0057] The handle body 2 has a closed position flush with the door and an open position outside the door. The handle body 2 also has a protruding transmission seat 3 placed in the base 1. The transmission seat 3 moves synchronously with the handle body 2.

[0058] Control arm 4 is connected to unlocking component. The transmission seat 3 actuates control arm 4 as handle body 2 opens, thereby unlocking the door.

[0059] The handle 2 can be opened manually or electrically.

[0060] like Figures 2 to 6 As shown, specifically, the base 1 is also provided with a hovering assembly 5. The hovering assembly 5 includes a stop bar 5.1 set on the base 1, a blocking part 5.2 set on the transmission seat 3, and a spring 5.3 abutting against the stop bar 5.1. The spring 5.3 applies a force to the stop bar 5.1 abutting against the transmission seat 3. In the trajectory of the handle body 2 from the closed position to the open position, the stop bar 5.1 can always abut against the transmission seat 3 under the action of the spring 5.3 and smoothly cross the blocking part 5.2. In the trajectory of the handle body 2 from the open position to the closed position, the stop bar 5.1 engages with the blocking part 5.2 and prevents the handle body 2 from continuing to rotate toward the closed position, so as to keep the handle body 2 in a hovering position away from the open position.

[0061] from Figure 2As can be seen from the diagram, as a further explanation of the stop lever 5.1, the base 1 is provided with an active space 1.1 for the transmission seat 3 to move within it. The control arm 4 is located on one side of the active space 1.1. The opening action of the transmission seat 3 within the active space 1.1 can actuate the control arm 4. The base 1 is also provided with a guide groove 1.2 communicating with the active space 1.1. The stop lever 5.1 is preferably inserted into the guide groove 1.2 and extends out of the active space 1.1, so that the stop lever 5.1 and the part of the base 1 through which it is inserted form a guide for the stop lever 5.1. The spring 5.3 is preferably placed in the end of the stop lever 5.1 away from the blocking part 5.2, with one end of the spring 5.3 abutting against the base 1 and the other end abutting against the stop lever 5.1, thereby driving the stop lever 5.1 to always move towards the transmission seat 3, so as to ensure that during the process of the handle body 2 returning from the open position to the closed position, the blocking part 5.2 can interfere with the end of the stop lever 5.1, thereby maintaining the hovering position of the handle body 2.

[0062] Furthermore, a slot 1.3 is provided in the base 1 corresponding to the inlet end of the guide groove 1.2. The inlet end of the guide groove 1.2 is provided through to allow the spring 5.3 and the stop rod 5.1 to be inserted. By providing a baffle in the slot 1.3, the spring 5.3 and the stop rod 5.1 are prevented from disengaging, and the baffle also provides an abutment position for the end of the spring 5.3.

[0063] As an example of the blocking part 5.2, the blocking part 5.2 refers to a step protruding from the stop lever 5.1 onto the transmission seat 3. The step-shaped blocking part 5.2 creates a height difference at its two ends. When the handle body 2 is in the closed position, the stop lever 5.1 is abutted against the relatively high position of the transmission seat 3 by the action of the spring 5.3. When the handle body 2 moves to the open position, the stop lever 5.1 smoothly crosses the blocking part 5.2 and abuts against the relatively low position of the transmission seat 3, in sync with the synchronous movement of the transmission seat 3 and the blocking part 5.2. Thus, when the handle body 2 returns to the closed position, it needs to overcome the obstruction of the stop lever 5.1 crossing the blocking part 5.2 from the relatively low position, thereby achieving hovering.

[0064] In this embodiment, a hovering component 5 is used to maintain the handle body 2 in a hovering position. The hovering position can be the open position of the handle body 2, or a certain rotational stroke relative to the open position. At least in the hovering position, the handle body 2 can be pried open, or a hand can be placed between the handle body 2 and the door to operate the handle body 2.

[0065] Of course, the hovering position can also be between the open and closed positions. The purpose of this method is to allow the handle body 2 to return to its original position by a certain amount of travel, avoiding the problem of collision noise caused by the handle body 2 returning to its original position too quickly at an excessively large angle.

[0066] As one embodiment of releasing the handle body 2 from suspension, the lever 5.1 can be actuated by an external force to move away from the blocking part 5.2, so as to allow the handle body 2 to return to the closed position. This external force can be manually pushed from outside the door, or it can be guided by a reset component provided in the base 1 to overcome the blocking part 5.2.

[0067] Continue to refer to Figures 2 to 6 As shown, as another embodiment of releasing the handle body 2 from the hover position, the base 1 is also provided with a reset component. The reset component is indirectly actuated by the opening action of the handle body 2, and the reset component gradually returns to its original position when the handle body 2 is in the open position. With the gradual return action, the stop lever 5.1 is gradually exerted with force to move away from the blocking part 5.2. In this way, the stop lever 5.1 can be controlled by the reset component to overcome the blocking part 5.2, thereby realizing the automatic return of the handle body 2 in the hover position. The gradual return action of the reset component is realized by the damping component applied to the reset component to prevent the reset component from returning too quickly and affecting the holding time of the hover position.

[0068] As a further embodiment of the reset assembly, the reset assembly includes a cam disk 6 and a first torsion spring 7 acting on the cam disk 6. The first torsion spring 7 applies a reset force to rotate the cam disk 6 toward the stop lever 5.1. Both the cam disk 6 and the first torsion spring 7 are disposed within the movable space 1.1. During the process of the handle body 2 moving from the closed position to the open position, the transmission seat 3 indirectly actuates the cam disk 6, thereby driving the cam disk 6 to rotate to a position ready to guide the stop lever 5.1 away from the blocking part 5.2. The cam disk 6 is provided with a slope. The ramp 6.1 has a height difference matching the blocking part 5.2. The stop bar 5.1 has a first guide part 5.11 opposite to the ramp 6.1. When the handle body 2 is in the open position, the stop bar 5.1 abuts against the ramp 6.1 under the action of the spring 5.3. The ramp 6.1 guides the stop bar 5.1 to gradually move away from the blocking part 5.2 by returning to its original position. The interference time between the blocking part 5.2 and the stop bar 5.1 is controlled by the rotation of the cam disk 6, thereby controlling the hovering time of the handle body 2.

[0069] As a further explanation of ramp 6.1, provided that the stop lever 5.1 reaches the end of ramp 6.1, the height between the start and end of ramp 6.1 can be less than the height of the blocking part 5.2. The handle body 2 needs to overcome the height difference between ramp 6.1 and blocking part 5.2 through its own restoring force to achieve automatic reset after hovering. Of course, the height between the start and end of ramp 6.1 can also be greater than the height of blocking part 5.2 to ensure that the stop lever 5.1 is freed from the interference of blocking part 5.2, so that the handle body 2 automatically returns to its original position after hovering.

[0070] In the indirect transmission between the reset assembly and the transmission seat 3, the return rotation of the cam disk 6 is set to operate independently of the handle body 2 and the transmission seat 3. Preferably, a gear train is provided between the cam disk 6 and the transmission seat 3 to further reduce the reset rotation speed of the cam disk 6 through the reduction ratio between the gear trains.

[0071] The handle body 2 has a rotating shaft A, the cam disc 6 has a rotating shaft B parallel to the rotating shaft A, and the stop lever 5.1 is set parallel to the rotating shaft A.

[0072] like Figure 10 As shown, specifically, the base 1 is also provided with a damping assembly connecting the cam disk 6 and the transmission seat 3. The damping assembly includes a transmission member 8 and a damping gear 9 fixed on the cam disk 6. The transmission member 8 is provided with a gear part 8.1, and the damping gear 9 meshes with the gear part 8.1. The transmission member 8 is actuated to rotate by the opening action of the transmission seat 3, and the cam disk 6 is driven to rotate by the damping force and meshing force between the gear part 8.1 and the damping gear 9. The engagement between the damping assembly and the cam disk 6 always applies a force that hinders the return of the cam disk 6, thereby slowing down the return rate of the cam disk 6. The damping gear 9 is detachable, and the return speed of the cam disk 6 can be controlled by the number of teeth between the damping gear 9 and the gear part 8.1, thereby controlling the time when the stop lever 5.1 is guided away from the blocking part 5.2.

[0073] The transmission component 8, gear part 8.1, and cam disk 6 are coaxially arranged. When the handle body 2 is held in the suspended position, the cam disk 6 rotates back under the action of the first torsion spring 7. The damping gear 9 on it revolves around the gear part 8.1 and rotates on its own axis. The transmission seat 3 restricts the rotation of the transmission component 8, thereby allowing the cam disk 6 to rotate independently of the transmission component 8. The transmission component 8 is connected to the second torsion spring 10, which applies a resetting force to the transmission component 8. The fixed ends of the first torsion spring 7 and the second torsion spring 10 are both engaged on the base 1.

[0074] like Figures 7 to 9 and Figure 11 As shown, as a further embodiment of the transmission member 8, the transmission member 8 also includes a transmission part 8.2, which is coaxially arranged with the gear part 8.1. The force of the second torsion spring 10 also actuates the handle body 2 towards the closed position through the transmission member 8. The transmission part 8.2 is placed in the transmission seat 3 in the closed position and prevents the transmission seat 3 from moving. The handle body 2 is manually moved to the open position, and the transmission part 8.2 is actuated to the open position through the transmission seat 3. The transmission part 8.2 engages with the outer wall of the transmission seat 3, and the stop bar 5.1 stops the transmission seat 3, so that the position of the transmission seat 3 is fixed. Thus, the engagement between the transmission seat 3 and the transmission part 8.2 prevents the transmission member 8 from rotating.

[0075] Specifically, the transmission part 8.2 is located near the free end of the second torsion spring 10. The transmission member 8 is located on one side of the transmission part 8.2 and has a first arc part 8.3 that protrudes outward. The transmission part 8.2 protrudes from the first arc part 8.3. The transmission member 8 is located on the other side of the transmission part 8.2 and has a second arc part 8.4 that is recessed inward. The first arc part 8.3 abuts against the inner wall of the transmission seat 3 in the closed position. The second arc part 8.4 is located near the rotation center of the transmission member 8.

[0076] In this embodiment, the transmission base 3 includes an unlocking part 3.2 and an actuating part 3.1 spaced apart. When the handle body 2 is in the closed position, the transmission component 8 is placed between the unlocking part 3.2 and the actuating part 3.1. When the handle body 2 is in the open position, the transmission component 8 is engaged with the outer wall of the actuating part 3.1. The unlocking part 3.2 drives the control arm 4 as the handle body 2 is opened and unlocked.

[0077] Specifically, the actuating part 3.1 has an actuating surface 3.11 disposed on the inner wall of the transmission seat 3, and a mating surface 3.12 disposed on the outer wall of the transmission seat 3.

[0078] like Figure 3 , Figure 4 and Figure 7 As shown, in the closed position, the actuating surface 3.11 abuts against the transmission part 8.2 and faces the second arc part 8.4. At this time, the transmission member 8 holds the handle body 2 in the closed position under the force of the second torsion spring 10, and the first arc part 8.3 with outward arc protrusion abuts against the inner wall of the unlocking part 3.2.

[0079] like Figure 5 and Figure 8 As shown, during the process of the handle body 2 moving from the closed position to the open position, the actuating surface 3.11 presses against the transmission part 8.2 as the handle body 2 moves, and drives the transmission component 8 to rotate. At this time, the first arc part 8.3 and the unlocking part 3.2 tend to move away from each other, and the second arc part 8.4 and the mating surface 3.12 of the actuating part 3.1 tend to mate and match. Meanwhile, the gear part 8.1 drives the damping gear 9 and the cam disk 6 due to the rotation of the transmission component 8, so that the cam disk 6 moves to a position ready to guide the stop lever 5.1 away from the blocking part 5.2.

[0080] In the open position, the mating surface 3.12 corresponding to the outside of the transmission seat 3 is in contact with the second arc portion 8.4, and the transmission portion 8.2 extends out of the actuating portion 3.1. At this time, the end of the actuating portion 3.1 abuts against the center of the rotating shaft of the transmission member 8 and is close to the side of the transmission portion 8.2, so that the return rotation of the transmission member 8 is restricted by the transmission seat 3. The stop bar 5.1 abuts against the transmission seat 3 under the action of the spring 5.3 and is ready to abut against the blocking portion 5.2.

[0081] like Figure 6 and Figure 9 As shown, during the unlocking action, the unlocking part 3.2 of the handle body 2 pushes the control arm 4, and the actuating part 3.1 slides on the second arc part 8.4. The actuating part 3.1 slides towards the side of the transmission part 8.2. By controlling the hovering time, the user can press the handle body 2 to the open position and then hover before performing the unlocking action. After the unlocking action is completed, the handle body 2 automatically returns to the closed position.

[0082] When the handle 2 is released from the open position by hand, it enters the hover position. At this time, the stop lever 5.1 stops at the blocking part 5.2 on the transmission seat 3, keeping the handle 2 in the hover position. The cam disk 6 begins to rotate back under the action of the first torsion spring 7, while the transmission component 8 stops rotating due to the restriction of the rotation by the transmission seat 3. The damping gear 9 on the cam disk 6 and the gear part 8.1 that restricts rotation provide damping to the cam disk 6, thereby reducing the rotation speed of the cam disk 6. At this time, the ramp 6.1 slides relative to the second guide part 5.12 of the stop lever 5.1 and gradually guides the stop lever 5.1 away from the blocking part 5.2. As the cam disk 6 returns to its original position, the stop lever 5.1 completely disengages from the blocking part 5.2, and the handle 2 returns to its original position without obstruction. At the same time, the transmission component 8 also returns to its original position under the action of the second torsion spring 10. Of course, during this process, the meshing between the damping gear 9 and the gear part 8.1 always provides damping force that resists the return direction.

[0083] It is worth mentioning that, such as Figures 7 to 9 As shown, in the closed position, the force exerted by the transmission part 8.2 on the actuating surface 3.11 is nearly perpendicular, which improves the holding force of the first torsion spring 7 on the handle body 2 in the closed position; in the open position, the force exerted by the transmission part 8.2 on the actuating surface 3.11 is nearly perpendicular to the rotation center of the handle body 2. This arrangement helps to reduce the impact of the reset force of the transmission component 8 on the transmission seat 3 and the handle body 2 in the suspended position.

[0084] Preferably, the inner surface of the unlocking part 3.2 is inclined, and the first arc part 8.3 cooperates with the inner surface of the unlocking part 3.2 to improve the smoothness and stability of the transmission component 8 during the opening process of the handle body 2.

[0085] like Figure 2 and Figure 10As shown, as a further embodiment of the arrangement between the base 1 and the transmission base 3, the base 1 has two mounting edges extending into the interior of the door, with the aforementioned movable space 1.1 spaced between the two mounting edges. The cam disk 6 is provided with a first support shaft for accommodating the first torsion spring 7, and the transmission member 8 is provided with a second support shaft for accommodating the second torsion spring 10. The first support shaft and the second support shaft are rotatably disposed between the two opposite mounting edges. The fixed ends of the first torsion spring 7 and the second torsion spring 10 are correspondingly constrained between the two opposite mounting edges. The cam disk 6 and the transmission member 8 are provided with hook portions for the free ends of the first torsion spring 7 and the second torsion spring 10 to engage.

[0086] Based on the above arrangement, the cam disk 6 and the transmission component 8 are coaxially arranged, and there is a rotating shaft B parallel to the rotating shaft A. The hovering component 5 is arranged between the rotating shaft A and the rotating shaft B. Through the above improvements, the internal structural design space of the base 1 is optimized, the space utilization rate is improved, and the arrangement is simple.

[0087] Specifically, a stop block 5.4 is detachably embedded in the transmission seat 3, and the blocking part 5.2 is formed on the stop block 5.4. Therefore, by replacing the stop block 5.4, the step height or step shape of the blocking part 5.2 can be adjusted to control the speed at which the stop lever 5.1 overcomes and moves away from the blocking part 5.2. Figure 12 As shown, for example, the blocking part 5.2 can be set as an inclined surface. Furthermore, the end of the stop bar 5.1 can also be set as an inclined surface, so that in the hovering position, the blocking part 5.2 and the end of the stop bar 5.1 abut against each other at an inclined surface, thereby improving the stability in the hovering position.

[0088] Preferably, the stop 5.4 is embedded in the unlocking part 3.2, and the stop 5.4 is arranged in an arc shape and matches the rotation trajectory of the handle body 2.

[0089] Specifically, the stop block 5.4 is provided with a first slide rail 5.41 and a second slide rail 5.42 at the front and rear of the blocking part 5.2. The first slide rail 5.41 allows the stop lever 5.1 to move between the open position and the hovering position, and the second slide rail 5.42 allows the stop lever 5.1 to move between the hovering position and the closed position.

[0090] Specifically, the stop lever 5.1 is provided with a second guide part 5.12 for engaging with the blocking part 5.2. The second guide part 5.12 is positioned facing the stop block 5.4. During the rotation of the handle body 2, the second guide part 5.12 is kept in sliding engagement with the stop block 5.4 under the action of the spring 5.3.

[0091] Alternatively, the first guide portion 5.11 and the second guide portion 5.12 can be rollers, such as bearing components. Of course, the first guide portion 5.11 and the second guide portion 5.12 can also be provided as protruding ribs to reduce the friction area.

[0092] Among them, the first guide part 5.11 and the second guide part 5.12 of the stop lever 5.1 and the stop block 5.4 can be made of materials with low friction coefficient or self-lubricating properties to reduce the noise generated during the operation of each component.

[0093] In the above embodiment, a reset torsion spring 2.1 is provided on the handle body 2 to provide a force for resetting the handle body 2 to the closed position. The reset torsion spring is specifically sleeved on the rotating shaft A.

[0094] A method for operating a suspended parking door handle, applied to the aforementioned suspended parking door handle, includes the following steps:

[0095] A. 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. The stop lever 5.1 is held in a pressing posture by the spring 5.3 and engaged with the transmission seat 3. The transmission component 8 is pushed by the transmission seat 3 on the handle body 2. At the same time, the transmission component 8 drives the cam disk 6 to rotate through the damping gear 9, so that the first guide part 5.11 enters the starting section of the ramp 6.1, and the transmission component 8 leaves the transmission seat 3 and engages with the outer wall of the transmission seat 3.

[0096] B. Hover the handle 2, and keep the stop lever 5.1 in a pressing position to engage with the blocking part 5.2. At this time, the cam disk 6 rotates in the opposite direction by the first torsion spring 7, and the first guide part 5.11 gradually follows the movement along the ramp 6.1 until the stop lever 5.1 is guided to gradually move away from the blocking part 5.2 and is resisted by the force of the second torsion spring 10.

[0097] C. The handle body 2 returns to its original position, the first guide part 5.11 enters the end section of the ramp 6.1, at this time the stop bar 5.1 is completely away from the blocking part 5.2, the handle body 2 returns to its original position under the reset force, the blocking part 5.2 passes the stop bar 5.1 as the handle body 2 returns to its original position, and the transmission component 8 is placed in the transmission seat 3.

[0098] D. Unlock handle body 2, pull handle body 2, the unlocking part 3.2 of handle body 2 pushes control arm 4, the actuation part 3.1 slides toward the side of transmission part 8.2, and transmission member 8 remains in the current position.

[0099] Specifically, during the process from step A to step B, as the handle body 2 rotates, the transmission part 8.2 of the transmission component 8 rotates and moves away from the actuation surface 3.11 of the actuation part 3.1, and abuts against the outer end of the actuation part 3.1. At this time, the second arc part 8.4 fits against the mating surface 3.12 of the actuation part 3.1.

[0100] As the handle body 2 moves, the blocking part 5.2 abuts against the second guide part at the end of the stop lever 5.1. At this time, the stop lever 5.1 keeps the handle body 2 in the suspended position through the transmission seat 3. The transmission component 8 is blocked by the actuating part 3.1 of the transmission seat 3 and its rotation is restricted. The cam disk 6 is ready to return to its original position under the action of the first torsion spring 7.

[0101] Specifically, in steps B to C, the cam disk 6 enters the return action and is forced to overcome the damping force from the damping gear 9 and the meshing force between the damping gear 9 and the gear part 8.1 to slow down the return speed. The ramp 6.1 gradually guides the first guide part on the stop lever 5.1 and drives the stop lever 5.1 to move away from the blocking part 5.2, while overcoming the resistance of the spring 5.3, until the stop lever 5.1 is away from the blocking part 5.2. The handle body 2 returns to its original position under the action of its return torsion spring 2.1, and the transmission component 8 returns to its original position under the action of the second torsion spring 10. The transmission component 8 further drives the damping gear 9 to provide the return force for the cam disk 6. At the same time, the cam disk 6 returns to its original position under the action of the first torsion spring 7. That is, the handle body 2 and the cam disk 6 quickly return to their original positions after the hovering is completed.

[0102] Specifically, in step D, the mating surface 3.12 on the actuating part 3.1 slides against the second arc portion 8.4 on the transmission member 8, and the sliding direction is toward the transmission part 8.2, without affecting the current position of the transmission member 8.

[0103] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. 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.
