Description

Technical Field

[0001] This utility model relates to the field of automotive door technology, and in particular to an outward-folding door handle. Background Technology

[0002] Existing outward-folding door handles typically connect the drive mechanism to the handle's swing arm. If only one side of the swing arm is driven, it will cause uneven force distribution. If both sides of the swing arm are driven, it will result in a complex structure and a large space occupation. Utility Model Content

[0003] To address the issues of uneven force distribution, complex structure, and large space occupation in the drive mechanism of existing outward-folding door handles, this invention provides a space-saving outward-folding door handle with a smooth driving process.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An outward-folding door handle includes:

[0006] Base

[0007] A handle assembly, comprising a handle and handle arms located at both ends of the handle, wherein the handle arms are rotatably connected to a base, and a connecting rod is connected between the two handle arms.

[0008] A roller, which is rotatably connected to a connecting rod;

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

[0010] An elastic reset element is disposed between the handle assembly and the base;

[0011] An unlocking switch element is mounted on a base;

[0012] The unlocking swing arm is rotatably connected to the base. 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 by a set stroke.

[0014] Furthermore, the unlocking arm is also connected to a cable. The unlocking arm has an arc surface that contacts the trigger face. The arc surface is centered on the rotation center of the unlocking arm. When the unlocking microswitch passes the trigger face and contacts the arc surface, it enters the mechanical unlocking stroke. When the microswitch contacts the arc surface, it will not be pressed down further, thus protecting the microswitch.

[0015] Furthermore, at least one end of the handle assembly is equipped with a torsion spring, the first end of which is limited on the handle assembly, and the second end of which overlaps the handle assembly and extends from the overlap position. When the mechanical unlocking stroke is entered, the second end of the torsion spring rests on the base, thereby applying an 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. A drive block is provided at the junction of the handle arm and the connecting rod. The drive block is provided with a first trigger part for triggering the first micro switch and a second trigger part for triggering the second micro switch.

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

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

[0019] Furthermore, the door sheet metal has a groove for inserting a handle, and the handle has legs extending from both sides. The legs pass through holes on both sides of the groove and are detachably fixed to the handle arm at the corresponding position.

[0020] Furthermore, it also includes an auxiliary installation mechanism, which includes an auxiliary installation slider slidably disposed on the base, one of the handle arms having an auxiliary installation hole, the auxiliary installation slider having an auxiliary installation post for inserting into the auxiliary installation hole, and a limiting mechanism connected to the base for limiting the auxiliary installation slider to a position close to or far from the handle arm.

[0021] Furthermore, the limiting mechanism includes a screw, and the base is threaded with a screw. The screw abuts against the auxiliary mounting slider, thereby inserting the auxiliary mounting post 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 located on the side away from the screw and is used to disengage the auxiliary mounting post from the auxiliary mounting hole.

[0022] Beneficial effects:

[0023] (1) The driving position of the driving mechanism is set in the middle of the connecting rod inside the handle, so that the force is applied evenly. The connecting rod is equipped with rollers that cooperate with the cam to reduce friction and make the driving process smooth.

[0024] (2) The outward-folding handle of this utility model has both electronic unlocking and mechanical emergency unlocking methods. Both unlocking methods are achieved through the unlocking swing arm, and the structure is highly integrated. In addition, during the mechanical unlocking process, an extra load is applied to the mechanical unlocking process by the torsion spring set on the handle assembly, which improves the user experience and has a simple structure.

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

[0026] (4) Hall sensors can be used instead of microswitches to control the handle travel, which is suitable for different vehicle models;

[0027] (5) By using an auxiliary installation slider, the handle arm is positioned in the extended state when the handle assembly is shipped, facilitating the installation of the handle. Then, the auxiliary installation slider can be retracted to a position away from the handle arm without affecting the normal operation of the handle assembly. In this way, it is not necessary to power on the actuator and drive the handle arm to rotate every time during installation, saving installation time and improving efficiency.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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 utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] 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.

[0039] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this 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 does not need to be aligned for further discussion in subsequent figures.

[0040] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0041] 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.

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.

[0042] 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 cannot be construed as limiting the scope of protection of this utility model.

[0043] like Figures 1-7 This utility model discloses an outward-tilting door handle, comprising a base 1, a handle assembly 2, a roller 25, an actuator 3, an elastic reset 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 located at both ends of the handle 21. The handle swing arms 23 are rotatably connected to the base 1, and a connecting rod 24 is connected between the two handle swing arms 23. The roller 25 is rotatably connected to the connecting rod 24. The output end of the actuator 3 is connected to a drive cam 4, and the cam surface of the drive cam 4 contacts the roller 25 to drive the handle assembly 2 to tilt outward. The elastic reset member 5 is disposed between the handle assembly 2 and the base 1. The unlocking switch element 6 is mounted on the base 1. The unlocking swing arm 7 is rotatably connected to the base 1 and is driven to rotate by the handle swing arm 23, triggering the unlocking switch element 6.

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

[0045] The unlocking arm 7 is also connected to a cable. The unlocking arm 7 has an arc surface 72 that mates with the trigger surface 71. The arc surface 72 is centered on the rotation center of the unlocking arm 7. When the unlocking micro switch passes the trigger surface 71 and contacts the arc surface 72, it enters the mechanical unlocking stroke.

[0046] At least one end of the handle assembly 2 is equipped with a torsion spring 8. The first end of the torsion spring 8 is limited on the handle assembly 2, and the second end of the torsion spring 8 overlaps the handle assembly 2 and extends from the overlap position. When entering the mechanical unlocking stroke, the second end of the torsion spring 8 overlaps the base 1, thereby applying an additional load to the mechanical unlocking stroke.

[0047] To detect whether the handle is in the initial or extended position, a detection element is required. In one embodiment, the base 1 is also equipped with a first microswitch 9 and a second microswitch 10 for detecting the position of the handle 21. A drive block 26 is provided at the junction of the handle arm 23 and the connecting rod 24. The drive block 26 has a first trigger part 261 for triggering the first microswitch 9 and a second trigger part 262 for triggering the second microswitch 10. In another embodiment, the actuator 3 includes an actuator, or an actuator with Hall sensor functionality, for controlling the position of the handle.

[0048] To prevent accidental triggering of the door, an inertial lock 11 is installed on the base 1 to block the unlocking swing arm 7.

[0049] like Figures 1-2The door sheet metal has a groove for inserting the handle 21. The handle 21 has legs 22 extending from both sides. The legs 22 pass through the holes on both sides of the groove and are detachably fixed to the handle arm 23 at the corresponding position. The connection between the legs 22 and the handle arm 23 can be snap-fit ​​or connected by screws, etc.

[0050] The present invention provides an outward-opening vehicle door handle, which further includes an auxiliary installation mechanism. The auxiliary installation mechanism includes an auxiliary installation slider 12 slidably mounted on a base 1. One of the handle arms 23 has an auxiliary installation hole 231. The auxiliary installation slider 12 has an auxiliary installation post 121 for inserting into the auxiliary installation hole 231. The base 1 is also connected to a limiting mechanism for limiting the auxiliary installation slider 12 to a position close to or away from the handle arm 23. In a preferred embodiment, the limiting mechanism includes a screw 13, which is threaded onto the base 1. The screw 13 abuts against the auxiliary installation slider 12, thereby inserting the auxiliary installation post 121 of the auxiliary installation slider 12 into the auxiliary installation hole 231. The limiting mechanism also includes a spring, which is installed between the auxiliary installation slider 12 and the base 1. The spring is located on the side away from the screw 13 and is used to disengage the auxiliary installation post 121 from the auxiliary installation hole 231.

[0051] When the handle assembly 2 leaves the factory, all parts except the handle 21 are mounted 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. So when the base is installed on the door sheet metal, the handle 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 arm 23. This eliminates the need to power on the actuator 3 and drive the handle arm 23 to rotate every time it is installed, saving installation time. After the connection is completed, the screw 13 is removed. The auxiliary mounting slider 12 moves away from the handle arm 23 under the action of the spring, the auxiliary mounting post 121 is removed from the auxiliary mounting hole 231, and the handle arm 23 returns to its free position. Under the action of the spring, the auxiliary mounting slider 12 is held in a position away from the handle arm 23, so as not to affect the movement of the handle assembly 2.

[0052] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
