Description

Technical Field

[0001] The present invention relates to the technical field of automobile doors, in particular to an outward-flipping door handle. Background Art

[0002] Existing outward-flip door handles usually connect the drive mechanism to the swing arm of the handle. If only one side of the swing arm is driven, uneven force will be caused. If the swing arms on both sides are driven, the structure will be complicated and a large space will be occupied. Summary of the Invention

[0003] In order to solve the problems of uneven force, complex structure and large space occupied by the driving arm of the driving mechanism of the outward-flipping handle in the prior art, the present invention provides an outward-flipping door handle that saves space and has a smooth driving process.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] An outward-flipping vehicle door handle, comprising:

[0006] base,

[0007] A handle assembly, the handle assembly comprising a handle and handle swing arms located at both ends of the handle, the handle swing arms being rotatably connected to the base, and a connecting rod being connected between the handle swing arms on both sides;

[0008] A roller, the roller being rotatably connected to the connecting rod;

[0009] An actuator, wherein the output end of the actuator is connected to a driving cam, and the cam surface of the driving cam contacts the roller to drive the handle assembly to flip outward;

[0010] An elastic reset member, the elastic reset member being arranged between the handle assembly and the base;

[0011] An unlocking switch element, wherein the unlocking switch element is mounted on the base;

[0012] An unlocking swing arm is rotatably connected to the base, and the unlocking swing arm is driven to rotate by the handle swing arm and triggers the unlocking switch element.

[0013] Furthermore, the unlocking switch element includes an unlocking micro switch, and the unlocking swing arm is provided with a trigger surface for pressing the unlocking micro switch down to a set stroke.

[0014] Furthermore, a pull cable is connected to the unlocking swing arm, which has an arcuate surface that contacts the trigger surface. The arcuate surface is centered at the rotation center of the unlocking swing arm. When the unlocking microswitch passes the trigger surface and contacts the arcuate surface, it enters the mechanical unlocking stroke. When the microswitch contacts the arcuate surface, it will not be further depressed, thus protecting the microswitch.

[0015] Furthermore, a torsion spring is installed at at least one end of the handle assembly, the first end of the torsion spring is limited on the handle assembly, the second end of the torsion spring is overlapped on the handle assembly and the end extends from the overlap position, when entering the mechanical unlocking stroke, the second end of the torsion spring is overlapped on the base, thereby applying additional load to the mechanical unlocking stroke.

[0016] Furthermore, the base is also equipped with a first micro switch and a second micro switch for detecting the position of the handle, and a driving block is provided at the junction of one of the handle swing arms and the connecting rod, and the driving block is provided with a first triggering part for triggering the first micro switch and a second triggering part for triggering the second micro switch.

[0017] Furthermore, the actuator includes an actuator, or includes an actuator with a Hall sensor function.

[0018] Furthermore, an inertia lock for blocking the unlocking swing arm is installed on the base.

[0019] Furthermore, the door sheet metal has a groove for embedding the handle, and legs extend on both sides of the handle. The legs pass through the holes on both sides of the groove and are detachably fixed to the handle arms at the corresponding positions.

[0020] Furthermore, it also includes an auxiliary installation mechanism, which includes an auxiliary installation slider slidingly set on the base, one of the handlebar arms is provided with an auxiliary installation hole, and the auxiliary installation slider is provided with an auxiliary installation column for inserting into the auxiliary installation hole. The base is also connected to a limiting mechanism for limiting the auxiliary installation slider to a position close to or away from the handlebar arm.

[0021] Furthermore, the limiting mechanism includes a screw, which is threadedly connected to the base, and the screw presses against the auxiliary mounting slider, thereby inserting the auxiliary mounting column of the auxiliary mounting slider into the auxiliary mounting hole. The limiting mechanism also includes a spring, which is installed between the auxiliary mounting slider and the base. The spring is arranged on the side away from the screw and is used to disengage the auxiliary mounting column from the auxiliary mounting hole.

[0022] Beneficial effects:

[0023] (1) The present invention sets the driving position of the driving mechanism at the middle position of the connecting rod inside the handle, so that the force is evenly applied, and a roller is provided on the connecting rod to cooperate with the cam to reduce friction and make the driving process smooth;

[0024] (2) The outward-turning handle of the present invention has both an electronic unlocking mode and a mechanical emergency unlocking mode. Both unlocking modes are achieved through an unlocking swing arm, and the structure has a high degree of integration. In addition, during the mechanical unlocking process, an additional load is applied to the mechanical unlocking process by a torsion spring provided on the handle assembly, thereby improving the user experience and having a simple structure.

[0025] (3) The position of the handle assembly is detected by setting two micro switches, and the driving parts for driving the two micro switches are respectively set on the same driving block, which saves space and makes the structure more integrated;

[0026] (4) Hall sensors can be used instead of micro switches to control the handle travel, adapting to different car models;

[0027] (5) By using the auxiliary installation slider, the handlebar arm is positioned in the extended position when the handlebar assembly is shipped, which facilitates the installation of the handlebar. The auxiliary installation slider can then be returned to a position away from the handlebar arm without affecting the normal operation of the handlebar assembly. In this way, there is no need to energize the actuator and drive the handlebar arm to rotate each time the handlebar assembly is installed, which saves installation time and improves efficiency.

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0039] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be aligned for further discussion in subsequent drawings.

[0040] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0042] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0043] like Figures 1 to 7, which is an outward-flipping door handle of the present invention, includes a base 1, a handle assembly 2, a roller 25, an actuator 3, an elastic return member 5, an unlocking switch element 6 and an unlocking swing arm 7. The handle assembly 2 includes a handle 21 and handle swing arms 23 at both ends of the handle 21. The handle swing arm 23 is rotatably connected to the base 1, and a connecting rod 24 is connected between the handle swing arms 23 on both sides; the roller 25 is rotatably connected to the connecting rod 24; the output end of the actuator 3 is connected to a driving cam 4, and the cam surface of the driving cam 4 contacts the roller 25, so as to drive the handle assembly 2 to flip outward; the elastic return member 5 is arranged between the handle assembly 2 and the base 1; the unlocking switch element 6 is installed on the base 1; the unlocking swing arm 7 is rotatably connected to the base 1, and the unlocking swing arm 7 is driven to rotate by the handle swing arm 23 and triggers the unlocking switch element 6.

[0044] The unlocking switch element 6 includes an unlocking micro switch, and the unlocking swing arm 7 is provided with a trigger surface 71 for pressing the unlocking micro switch down to a set stroke.

[0045] A pull rope is also connected to the unlocking swing arm 7. The unlocking swing arm 7 is provided with an arc surface 72 that docks with the trigger surface 71. The arc surface 72 takes the rotation center of the unlocking swing arm 7 as the center of the circle. When the unlocking micro switch passes the trigger surface 71 and contacts the arc surface 72, it enters the mechanical unlocking stroke.

[0046] A torsion spring 8 is installed at at least one end of the handle assembly 2. The first end of the torsion spring 8 is limited on the handle assembly 2, and the second end of the torsion spring 8 is overlapped on the handle assembly 2 and the end extends from the overlap position. When entering the mechanical unlocking stroke, the second end of the torsion spring 8 is overlapped on the base 1, thereby applying additional load to the mechanical unlocking stroke.

[0047] In order to reflect whether the handle is in the initial position or the deployed position, a detection element is required. As an embodiment, the base 1 is also mounted with a first microswitch 9 and a second microswitch 10 for detecting the position of the handle 21. A driving block 26 is provided at the intersection of one of the handle swing arms 23 and the connecting rod 24. The driving block 26 includes a first triggering portion 261 for triggering the first microswitch 9 and a second triggering portion 262 for triggering the second microswitch 10. As another embodiment, the actuator 3 includes an actuator, or an actuator with a Hall sensor function, for controlling the position of the handle.

[0048] In order to prevent the vehicle door from being triggered by mistake, an inertia lock 11 is installed on the base 1 for blocking the unlocking swing arm 7.

[0049] like Figures 1-2 There is a groove on the door sheet metal for the handle 21 to be embedded, and legs 22 extend on both sides of the handle 21. The legs 22 pass through the holes on both sides of the groove and can be detachably fixed to the handle swing arms 23 at the corresponding positions. The connection between the legs 22 and the handle swing arms 23 can be snap-fitted or connected by screws.

[0050] An outward-flip door handle of the present invention also includes an auxiliary mounting mechanism, which includes an auxiliary mounting slider 12 slidably disposed on a base 1, wherein one handle swing arm 23 is provided with an auxiliary mounting hole 231, and the auxiliary mounting slider 12 is provided with an auxiliary mounting post 121 for inserting into the auxiliary mounting hole 231. The base 1 is also connected to a limiting mechanism for limiting the auxiliary mounting slider 12 to a position close to or away from the handle swing arm 23. As a preferred embodiment, the limiting mechanism includes a screw 13, and the screw 13 is threadedly connected to the base 1. The screw 13 presses against the auxiliary mounting slider 12, thereby inserting the auxiliary mounting post 121 of the auxiliary mounting slider 12 into the auxiliary mounting hole 231. The limiting mechanism also includes a spring, which is installed between the auxiliary mounting slider 12 and the base 1. The spring is provided on the side away from the screw 13 and is used to disengage the auxiliary mounting post 121 from the auxiliary mounting hole 231.

[0051] When the handle assembly 2 leaves the factory, all parts except the handle 21 are installed on the base 1. At this time, the auxiliary mounting post 121 is inserted into the auxiliary mounting hole 231 under the action of the screw 13. In this way, when the base is installed on the door sheet metal, the handle swing arm 23 is turned outward to the outside of the groove of the door sheet metal, which facilitates the connection between the handle 21 and the handle swing arm 23. In this way, there is no need to energize the actuator 3 and drive the handle swing arm 23 to rotate every time it is installed, saving installation time. After the two are connected, the screw 13 is withdrawn, and the auxiliary mounting slider 12 is moved away from the handle swing arm 23 under the action of the spring. The auxiliary mounting post 121 is withdrawn from the auxiliary mounting hole 231, and the handle swing arm 23 is restored to freedom. Under the action of the spring, the auxiliary mounting slider 12 remains in a position away from the handle swing arm 23, so as not to affect the movement of the handle assembly 2.

[0052] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
