Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive door handle technology, and in particular to a double-swing arm concealed door handle. Background Technology
[0002] In the existing technology, the swing arm of the rotary handle is driven by an actuator, which requires converting the actuator's push into the swing of the swing arm. The rotary actuator directly drives the handle leg, but the actuator has low power and the effective torque transmitted to the handle is also small, which cannot meet the ice-breaking requirements. Summary of the Invention
[0003] To address the problem of low ice-breaking ability of existing rotary handles, this invention provides a double-swing arm concealed door handle that improves the ice-breaking ability of rotary handles.
[0004] The technical solution adopted by this invention to solve its technical problem is:
[0005] A concealed door handle for a double-swing arm vehicle includes:
[0006] Base
[0007] The handle, which is rotatably mounted on the base, has supporting legs.
[0008] The first swing arm is disposed on the first side of the outrigger and is connected to the outrigger via a transmission mechanism.
[0009] The second swing arm is disposed on the second side of the outrigger and is connected to the outrigger via a transmission mechanism.
[0010] The actuator is mounted on the base.
[0011] A driving component is connected to the rotation output end of the actuator. The rotation axis of the driving component is parallel to the thickness direction of the handle. The side of the driving component contacts the first swing arm and is used to drive the first swing arm to rotate, thereby driving the handle to rotate from the initial closed position to the unfolded position.
[0012] Furthermore, the second swing arm is located above the outrigger, and a cable is connected to the upper end of the second swing arm. A first signal switch is provided on the base, which is triggered by the second swing arm. The first signal switch is located at the upper end of the base.
[0013] Furthermore, a second signal switch is provided on the base, which is triggered by the upper end of the first swing arm.
[0014] Furthermore, the second swing arm is connected to an elastic reset mechanism.
[0015] Furthermore, the base is equipped with an inertial lock, which, when rotated, blocks the second swing arm to prevent the second swing arm from pulling the cable and unlocking the car door.
[0016] Furthermore, the actuator includes a three-stage transmission mechanism, the first stage of which is a worm gear transmission mechanism, and the second and third stages of which are spur gear transmission mechanisms.
[0017] Furthermore, the actuator has a split housing, with all spur gears positioned on one of the split housings. Since the gear transmission center distance is fixed by only one housing, it is less affected by manufacturing precision, resulting in high positioning accuracy and low transmission noise.
[0018] Furthermore, the side of the drive component includes a cam surface and an arc surface concentric with the rotation center of the drive component. During the process of the handle moving from the initial closed position to the open position, the cam surface contacts the first swing arm, thereby driving the first swing arm to swing. After the handle is in the open position, the arc surface of the drive component contacts the first swing arm. The arc surface is centered with the rotation center of the drive component, so the first swing arm cannot be driven by the arc surface.
[0019] Furthermore, when the arc surface of the drive component contacts the first swing arm, the direction of the force exerted by the first swing arm on the drive component passes through the shaft of the drive component.
[0020] Furthermore, the actuator or base is provided with a first limiting part for limiting the rotational limit position of the drive member along the direction of driving the first swing arm and a second limiting part for limiting the return limit position of the drive member. During the handle unfolding process, when the arc surface of the drive member begins to contact the first swing arm, the drive member is located at the unfolding design position, and there is a first overtravel interval between the unfolding design position and the rotational limit position. After the handle is unfolded, the drive member stops in the first overtravel interval. During the handle return process, when the handle returns to the initial closed position, the drive member returns to the initial design position, and there is a second overtravel interval between the initial design position and the return limit position. After the handle returns, the drive member stops in the second overtravel interval.
[0021] Beneficial effects:
[0022] (1) The rotation output end of the actuator is connected to the drive component to realize the drive of the handle. The transmission efficiency is high. Then it is transmitted to the end of the outrigger through the first swing arm. Since the first swing arm is located on one side of the outrigger, the power of the actuator on the first swing arm is perpendicular to the thickness direction of the handle. Thus, without occupying the space in the thickness direction of the handle, the profile of the drive component and the swing arm can be adjusted to greatly increase the transmission power arm, thereby greatly improving the ice-breaking force of the handle and improving the adaptability of the handle. For example, it can be applied to off-road vehicles and other models with high environmental requirements.
[0023] (2) The first swing arm and the second swing arm are set separately on both sides of the handle, so that when the profile of the first swing arm (such as its length or the position of the rotation center) is adjusted to increase the lever arm, there is no restriction and the adjustment flexibility is good;
[0024] (3) Because the existing transmission mechanism is easy to add a transmission arm, the torque requirement of the actuator is small. If it is necessary to increase the ice-breaking force, it can be achieved by improving the performance of the actuator, and there is a lot of room for improvement.
[0025] (4) When the handle is in the extended position, if it is accidentally operated from outside the vehicle, an external force (e.g., >500N) is applied inward. Since the handle is connected to the first and second swing arms through the outriggers, the outriggers are relatively large, making the handle body stronger. The handle grip and the outriggers are not easily damaged. At the same time, the first swing arm contacts the arc surface of the drive component, and the force applied by the first swing arm to the drive component passes through the rotation center of the drive component, that is, the drive component is in the dead point position. Therefore, the drive component can also share some of the force, and the first swing arm and the drive component are not easily damaged. In summary, the overall structure of the handle has high strength, is more durable, is not easily damaged, and has good performance.
[0026] (5) Both the cable and the switch are placed on the top to avoid water residue and prevent the cable or switch from freezing and causing failure.
[0027] (6) By providing an arc surface on the drive component, during the handle unfolding process, after the handle body is unfolded to a specified angle, the drive component continues to rotate, but the position of the first swing arm remains unchanged. On the one hand, this ensures the unfolded position of the first swing arm, and on the other hand, the drive component can continue to rotate for a certain stroke and then stop within the first overstroke range, instead of stopping immediately. Therefore, it ensures that the actuator does not stall during the handle unfolding process. During the return process, the drive component has a second overstroke range. The drive component can continue to rotate for a certain stroke beyond the initial design position and then stop within the second overstroke range, instead of stopping immediately. This ensures that the actuator does not stall during the handle reset process.
[0028] (7) The first stage of the actuator is a worm gear drive, and the second and third stages are spur gear drives, which further improves the transmission efficiency. Attached Figure Description

[0039] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.
[0040] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0041] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0042] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0043] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0044] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
[0045] like Figures 1-8This invention relates to a double-swing arm concealed door handle, comprising a base 1, a handle 2, a first swing arm 3, a second swing arm 4, an actuator 5, and a drive member 6. The handle 2 is rotatably mounted on the base 1 and has a support leg 21. The first swing arm 3 is disposed on the first side of the support leg 21 and is throttle-connected to the support leg 21. The second swing arm 4 is disposed on the second side of the support leg 21 and is throttle-connected to the support leg 21. The second swing arm 4 and the support leg 21 may be, but are not limited to, gear transmission. The actuator 5 is mounted on the base 1, and the drive member 6 is connected to the rotation output end of the actuator 5. The rotation axis of the drive member 6 is parallel to the thickness direction of the handle 2. The side of the drive member 6 contacts the first swing arm 3 and is used to drive the first swing arm 3 to rotate, thereby at least driving the handle 2 to rotate from the initial closed position to the unfolded position.
[0046] like Figure 1 The example shows several positions of handle 2, where a represents handle 2 in the initial closed position, b represents handle 2 in the extended position, and after the actuator 5 receives the signal, it drives handle 2 from the initial closed position to the extended position, and c represents handle 2 in the unlocked position. When the human hand pulls handle 2 from the extended position to the unlocked position, the second swing arm 4 pulls the cable 8 to unlock.
[0047] like Figure 3 The second swing arm 4 is located above the support leg 21, and a cable 8 is connected to its upper end. A first signal switch 7 is provided on the base 1, which is triggered by the second swing arm 4. The first signal switch 7 is located at the upper end of the base 1. A second signal switch 9 is provided on the base 1, which is triggered by the upper end of the first swing arm 3. Both the first signal switch 7 and the second signal switch 9 can be selected, but are not limited to, microswitches. In this embodiment, when the handle 2 is in the initial closed position, the second swing arm 4 triggers the first signal switch 7; when the handle 2 is in the open position, the first swing arm 3 triggers the second signal switch 9.
[0048] A spring-loaded reset mechanism is connected to the second swing arm 4. The spring-loaded reset mechanism may be, but is not limited to, a torsion spring located at the rotation center of the second swing arm 4.
[0049] like Figure 4 An inertial lock 10 is provided on the base 1. After the inertial lock 10 rotates, it blocks the second swing arm 4 to prevent the second swing arm 4 from pulling the cable 8 and unlocking the car door.
[0050] like Figure 5 The side of the drive member 6 includes a cam surface 61 and an arc surface 62 concentric with the rotation center of the drive member 6. During the process from the initial closed position to the open position of the handle 2, the cam surface 61 contacts the first swing arm 3, thereby driving the first swing arm 3 to swing. After the handle 2 is in the open position, the arc surface 62 of the drive member 6 contacts the first swing arm 3. The arc surface 62 is centered with the rotation center of the drive member 6, so the first swing arm 3 cannot be driven by the arc surface 62.
[0051] like Figure 5 When the arc surface 62 of the driving component 6 contacts the first swing arm 3, the direction of the force exerted by the first swing arm 3 on the driving component 6 passes through the axis of rotation of the driving component 6. This is equivalent to the driving component 6 reaching its dead point position at this time, and the reaction force of the first swing arm 3 cannot make the driving component 6 move.
[0052] like Figure 3 and Figure 4 The actuator 5 or the base 1 is provided with a first limiting part 11 for limiting the rotation limit position of the drive member 6 along the direction of driving the first swing arm 3 and a second limiting part 12 for limiting the return limit position of the drive member 6. When the handle 2 is unfolded, the arc surface 62 of the drive member 6 begins to contact the first swing arm 3, the drive member 6 is located in the unfolded design position, and there is a first overtravel interval A between the unfolded design position and the rotation limit position. After the handle 2 is unfolded, the drive member 6 stops in the first overtravel interval A. When the handle 2 returns to the initial closed position, the drive member 6 returns to the initial design position, and there is a second overtravel interval B between the initial design position and the return limit position. After the handle 2 returns to the initial closed position, the drive member 6 stops in the second overtravel interval B.
[0053] like Figure 8 Actuator 5 comprises a three-stage transmission mechanism. The first stage is a worm gear transmission mechanism, while the second and third stages are spur gear transmission mechanisms. Actuator 5 has a split housing, with all the spur gears positioned on one of the split housings. Figure 8 The actuator 5 includes a first housing 51 and a second housing 52. A worm gear and several spur gears are installed between the first housing 51 and the second housing 52, wherein all the spur gears are positioned on the first housing 51, resulting in high positioning accuracy and low transmission noise.
[0054] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
