Detailed Implementation
[0030] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.
[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0033] One aspect of this application provides a swing-out concealed door handle, such as Figures 1 to 10 As shown, one preferred embodiment includes a base 100, a handle 300, an actuator 200, and an unlocking component 500. The base 100 has a storage cavity 110 for housing the handle 300, allowing the handle 300 to be rotatably mounted within the storage cavity 110 at its first end. When the door is not needed, the handle 300 can retract into the storage cavity 110, making its outer surface flush with the outer surface of the door. This improves the overall aesthetics of the vehicle and reduces wind resistance during driving. The unlocking component 500 is mounted on the lower part of the base 100 and cooperates with the handle 300 via a traction structure. The unlocking component 500 can also be connected to a door lock. The actuator 200 is installed on the back of the base 100. The actuator 200 can cooperate with the handle 300 through the output end. When the door needs to be opened, the actuator 200 can drive the handle 300 to rotate around the first end through the output end until it swings out of the storage cavity 110. Then the user can hold the handle 300 and continue to pull the handle 300 to swing it, so that the handle 300 drives the unlocking component 500 to pull the door lock to unlock the car door through the traction structure.
[0034] Understandably, the actuator 200 can directly drive the handle 300 to swing out from its retracted state, making its structure simpler compared to traditional swing-out handles. Furthermore, during unlocking, the handle 300 is simply connected to the unlocking component 500 via a traction structure, allowing for direct unlocking by pulling the handle 300 after it has been extended. Simplifying the structure of the concealed door handle effectively reduces overall assembly difficulty and precision requirements.
[0035] In this embodiment, as Figure 2 , Figure 4 , Figure 5 and Figure 9 As shown, a second through hole 130 is provided on the inner side of the storage cavity 110, through which the storage cavity 110 communicates with the back of the base 100. A stop block 320 is provided on the inner side of the handle 300, which can pass through the second through hole 130 to extend to the back of the base 100, and thus cooperate with the output end of the actuator 200. Therefore, when the door is opened, the actuator 200 can press the stop block 320 through its output end to drive the handle 300 to rotate around its first end until it is fully extended out of the storage cavity 110.
[0036] Specifically, such as Figure 5 , Figure 6 and Figure 9 As shown, the abutment 320 is eccentrically positioned with respect to the first end of the handle 300, and the end of the abutment 320 extends parallel to the rotation plane of the handle 300. Thus, when the actuator 200 presses the abutment 320 through its output end, the abutment 320 can generate a driving torque with the first end of the handle 300 as the fulcrum to drive the handle 300 to rotate.
[0037] In this embodiment, there are various structures in which the actuator 200 cooperates with the abutment block 320, including but not limited to the two described below.
[0038] Structure 1: The output end of the actuator 200 abuts against one side of the abutment block 320.
[0039] Structure 2: The output end of the actuator 200 is connected to the slot. The abutment 320 engages with the slot at its end, and the actuator 200 drives the handle 300 to rotate by pressing against the end of the abutment 320 through the side end of the slot.
[0040] It is understandable that in the above structure two, if it is necessary to ensure that the handle 300 can be pulled to unlock the door lock by continuing to pull after it is swung out, the length of the connecting groove needs to be greater than the size of the abutment 320, so as to ensure that when the handle 300 drives the unlocking component 500 to unlock, the connecting groove has enough reserved space to avoid interference with the abutment 320.
[0041] Of course, in order to further simplify the structure of the swing-out concealed door handle of this application, the cooperation structure of the actuator 200 and the abutment block 320 in this embodiment preferably adopts the structure described above.
[0042] To ensure that the handle 300 automatically resets after the car door is unlocked, such as... Figures 4 to 6 as well as Figure 9 As shown, the handle 300 is elastically rotatably connected to the base 100 via a torsion spring 700. The actuator 200 engages with one side of the stop block 320 via its output end. Thus, during the process of the actuator 200 driving the handle 300 to rotate around its first end through linear motion, and during the process of pulling the handle 300 to unlock the unlocking component 500, the torsion spring 700 remains compressed. When the handle 300 is released, it can return to its original position within the storage cavity 110 under the elastic force of the torsion spring 700.
[0043] Specifically, such as Figure 4 , Figure 6 and Figure 9 As shown, a rotating hole is provided at one end of the storage cavity 110, and the first end of the handle 300 is rotatably connected to the rotating hole through the installed rotating shaft 310. The torsion spring 700 is sleeved on the rotating shaft 310, and one end of the torsion spring 700 abuts against the handle 300, while the other end of the torsion spring 700 abuts against the base 100.
[0044] It should be understood that during the process of pulling the handle 300 from its extended position to drive the unlocking component 500 to unlock the door, the actuator 200 remains stationary. Therefore, after the door is unlocked and the handle 300 is released, there are two possible reset processes for the handle 300: First, the handle 300 can be directly reset to its position against the output end of the actuator 200 under the force of the torsion spring 700. Subsequently, the actuator 200 resets, and during the reset process, the handle 300 resets synchronously with the actuator 200 under the force of the torsion spring 700 until the handle 300 retracts back into the storage cavity 110. Second, during the process of the handle 300 driving the unlocking component 500 to unlock, the actuator 200 has already begun to reset; thus, after the handle 300 is released, it can directly retract into the storage cavity 110 under the force of the torsion spring 700. Therefore, in both the first and second processes mentioned above, the handle 300 undergoes a rigid impact reset process, which makes the handle 300 prone to damage, and the noise generated by the rigid impact is also relatively large.
[0045] Therefore, in order to avoid rigid reset of the handle 300, the handle 300 and the base 100 can be matched with a damping structure so that the impact force of the handle 300 can be reduced during the reset process.
[0046] Specifically, such as Figure 6 As shown, an arc-shaped rack plate 340 is provided on the upper surface of the handle 300 near the first end, and the center of the rack plate 340 coincides with the rotating shaft 310. A frictionally rotatable gear is provided on the upper end of the base 100 in the storage cavity 110; when the handle 300 is installed in the storage cavity 110, the rack plate 340 on the handle 300 can mesh with the gear installed in the storage cavity 110. Furthermore, during the reset process of the handle 300, the meshing of the gear with the rack plate 340 dissipates some of the elastic potential energy generated by the torsion spring 700, thereby effectively reducing the rotational speed of the handle 300 and reducing or avoiding rigid impact.
[0047] In this embodiment, as Figure 2 , Figure 3 and Figure 9 As shown, a drive component 400 is rotatably mounted on the back of the base 100. The drive component 400 is located between the actuator 200 and the stop block 320, and the output end of the actuator 200 and the stop block 320 respectively abut against the two sides of the drive component 400. Then, the actuator 200 drives the drive component 400 to squeeze the stop block 320, thereby causing the handle 300 to rotate around the first end.
[0048] It should be understood that because the receiving cavity 110 on the base 100 is recessed inward, the actuator 200 needs to be installed away from the receiving cavity 110 during installation. This results in a significant distance between the output end of the actuator 200 and the abutment 320, as well as a certain height difference. Directly connecting the actuator 200 to the abutment 320 would lead to a complex structure at the output end of the actuator 200, inevitably increasing the failure rate during operation. Therefore, to ensure a good connection between the actuator 200 and the abutment 320, a drive component 400 can be installed between them. The actuator 200 then indirectly presses the abutment 320 by pressing the drive component 400.
[0049] It is also understandable that the drive component 400 and the base 100 can be elastically connected directly via the torsion spring 700, or the torsion spring 700 may not be necessary. When the drive component 400 is connected to the base 100 via the torsion spring 700, the drive component 400 can be reset by the torsion spring 700 itself; if the drive component 400 is directly rotated, the drive component 400 can be reset by the reset spring force of the handle 300, which can further reduce the impact generated by the reset of the handle 300.
[0050] One embodiment of this application, such as Figure 3 , Figure 7 and Figure 9 As shown, the unlocking component 500 is elastically rotatably connected to the base 100 via a torsion spring 700, and the rotation plane of the unlocking component 500 is parallel to the rotation plane of the handle 300. When the handle 300 swings out of the storage cavity 110 under the drive of the actuator 200, the unlocking component 500 can be kept stationary by the traction structure. When the handle 300 is pulled further, the handle 300 can drive the unlocking component 500 to rotate and compress the torsion spring 700 via the traction structure, thereby allowing the unlocking component 500 to unlock the door by pulling the door lock.
[0051] Specifically, such as Figure 5 , Figure 7 and Figure 9 As shown, the unlocking component 500 is rotatably connected to the support shaft 140 located at the lower part of the base 100 via a rotating hole. A torsion spring 700 is sleeved on the support shaft 140, with one end of the torsion spring 700 abutting against the unlocking component 500 and the other end abutting against the base 100. A connecting part 520 is located on the unlocking component 500 at a position offset from the rotating hole. The connecting part 520 can connect to a door lock, so that as the unlocking component 500 rotates around the rotating hole under the drive of the traction structure, the connecting part 520 can pull the door lock to unlock it.
[0052] It should be understood that the structure of the door lock and the specific principle of the unlocking component 500 for unlocking are well-known technologies to those skilled in the art, and therefore will not be elaborated here.
[0053] In this embodiment, as Figure 6 , Figure 7 and Figure 9 As shown, the traction structure includes a traction rod 330 and a traction groove 510. The traction groove 510 is disposed on the upper end face of the unlocking component 500, and the traction rod 330 is disposed on the lower part of the handle 300. The traction rod 330 can pass through the storage cavity 110 and cooperate with the traction groove 510. When the handle 300 is retracted into the storage cavity 110, the traction rod 330 is located at the first end of the traction groove 510. When the actuator 200 drives the handle 300 to rotate around the first end to the outside of the storage cavity 110, the traction rod 330 can slide along the first end of the traction groove 510 to the second end. Then, when the handle 300 is pulled further, the traction rod 330 can drive the unlocking component 500 to rotate around the support shaft 140 by abutting against the second end of the traction groove 510 to achieve unlocking.
[0054] Specifically, such as Figure 4 and Figure 9 As shown, the storage cavity 110 is provided with a first through hole 120 on the side near the unlocking component 500, and the traction rod 330 can pass downward through the first through hole 120 to extend into the traction groove 510.
[0055] One embodiment of this application, such as Figure 3 , Figure 8 , Figure 9 and Figure 10 As shown, a sealing component 600 is installed on the side of the second through hole 130. When the handle 300 is retracted into the storage cavity 110, the handle 300 can fit tightly with the sealing component 600, thereby sealing the second through hole 130. This ensures the airtightness of the storage cavity 110 during vehicle operation, preventing rainwater and other substances from entering the interior of the door through the second through hole 130 and damaging internal components.
[0056] It is understandable that during vehicle operation, rainwater can seep into the storage cavity 110 through the gap between the handle 300 and the storage cavity 110. Rainwater in the upper part of the gap in the storage cavity 110 may flow along the abutment 320 into the interior of the door, potentially dripping onto components and causing electrical leakage. Therefore, to prevent rainwater from entering the door through the abutment 320, a sealing component 600 can be installed on the side of the second through hole 130. When the handle 300 is retracted into the storage cavity 110, the second through hole 130 is sealed by the contact between the handle 300 and the sealing component 600, thus preventing rainwater from flowing into the door.
[0057] In this embodiment, as Figure 8 and Figure 10 As shown, the sealing assembly 600 includes a retaining gasket 610 and a sealing gasket 620; the retaining gasket 610 is made of a rigid material and engages with the side of the second through hole 130, while the sealing gasket 620 is made of a soft material and is mounted on the retaining gasket 610. Thus, when the handle 300 is retracted into the storage cavity 110, the handle 300 can achieve a seal on the second through hole 130 by fitting its inner side against the sealing gasket 620.
[0058] Understandably, since the sealing gasket 620 is made of a soft material, such as rubber, directly connecting the sealing gasket 620 to the second through hole 130 would lead to an unstable installation structure for the sealing gasket 620. Therefore, a rigid material, such as a plastic fixing gasket 610, can be used to first establish a stable connection between the sealing gasket 620 and the second through hole 130. Subsequently, the sealing gasket 620 can be tightly connected to the fixing gasket 610, thereby ensuring the stability of the installation structure of the sealing gasket 620 while also reducing design complexity.
[0059] Specifically, such as Figure 8 and Figure 10As shown, the fixing pad 610 is generally rectangular and has an opening. Multiple snap fasteners 613 are provided on the side of the fixing pad 610, allowing it to engage with the side of the second through hole 130, thus achieving a stable connection between the fixing pad 610 and the base 100. A groove 611 is provided on the end face of the fixing pad 610 facing the storage cavity 110, and the sealing gasket 620 can be fitted into the groove 611 and tightly connected through a limiting structure.
[0060] The limiting structure includes multiple grooves 622 and multiple protrusions 612. The grooves 622 can be evenly distributed along the side of the sealing gasket 620, and the protrusions 612 can be evenly distributed along the side of the recess 611; alternatively, the grooves 622 can be evenly distributed along the side of the recess 611, and the protrusions 612 can be evenly distributed along the side of the sealing gasket 620. Thus, when the sealing gasket 620 is installed in the recess 611, the grooves 622 can engage with the corresponding protrusions 612, thereby ensuring the stability of the connection between the sealing gasket 620 and the fixing gasket 610.
[0061] In this embodiment, as Figure 8 and Figure 10 As shown, the end face of the sealing gasket 620 is provided with an outwardly extending edge 621, which is continuously provided; thus, when the handle 300 is retracted into the storage cavity 110, the inner side of the handle 300 can fit with the extension edge 621.
[0062] Understandably, because the sealing gasket 620 is relatively wide, it is not easily deformed. Therefore, if the inner side of the handle 300 is uneven when it is fitted with the end face of the sealing gasket 620, a gap will still occur between the sealing gasket 620 and the inner side of the handle 300. However, with the extension edge 621, because the extension edge 621 is thinner and more easily deformed, when the inner side of the handle 300 is uneven, the extension edge 621 can deform appropriately to ensure a tight fit with the inner side of the handle 300, thereby effectively ensuring the airtightness of the second through hole 130.
[0063] Another aspect of this application provides a vehicle including the aforementioned swing-out concealed door handle.
[0064] It is understood that the swing-out concealed door handle in this application can be applied not only to vehicles, but also to other fields.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
