Description

Technical Field

[0001] This invention relates to the field of vehicle door handle technology, specifically to an electrically operated, semi-retractable door handle. Background Technology

[0002] Existing electric vehicle door handles, such as the door handle disclosed in patent publication number CN105507699B, use a drive motor to rotate a gear paddle, which in turn rotates a double-fork rocker arm (main push link) of a certain length, thereby extending the outer handle and realizing the automatic extension of the door handle.

[0003] In actual use, since the gear propeller only acts on one end of the double fork rocker arm (main push link), the double fork rocker arm (main push link) is subjected to unbalanced force. In addition, since the related parts are made of plastic, the force applied to one side can easily cause the rocker arm to deform. This will cause the handle to open in a non-parallel manner, affecting the user experience.

[0004] Meanwhile, existing electric vehicle door handles use electronic unlocking. Users can trigger the electronic unlocking by touching or pressing the electronic components on the handle, thus unlocking the door. However, sometimes the electronic unlocking fails, causing the door to be unable to unlock. Therefore, existing doors are also equipped with a mechanical unlocking unit. The door handle triggers the mechanical unlocking unit by setting up a mechanical unlocking mechanism. The existing mechanical unlocking mechanism is generally formed by a rotating part inside the door handle connected to a cable. When the rotating part rotates, pulling the cable can trigger the mechanical unlocking unit. In relation to the handle structure mentioned above, if the main push link is directly connected to the cable, it is easy to accidentally trigger the mechanical unlocking unit when the handle is extended. Therefore, a new mechanical unlocking mechanism needs to be designed. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an electrically operated, semi-retractable handle that not only reduces deformation of the main push link and ensures smooth opening of the handle body, but also features a mechanical unlocking mechanism that allows the door to be unlocked mechanically when the electronic unlocking fails.

[0006] The technical solution is as follows: an electrically operated, semi-retractable handle, comprising:

[0007] A handle opening assembly is provided to extend the handle body from the base. The handle opening assembly includes a main push linkage mechanism, a linkage rod, a first return spring, and a driving device. The main push linkage mechanism is fork-shaped and includes a main push linkage. One end of the main push linkage is connected to the base, and the other end is connected to both ends of the handle body distributed laterally. The driving device is used to provide driving force from one side of the main push linkage to drive its rotation.

[0008] A mechanical unlocking mechanism, which is used to trigger the mechanical unlocking unit;

[0009] The feature is that the main push link mechanism further includes a balance bar with a certain rigidity. The balance bar extends along the transmission direction of the driving force and its two ends are respectively connected to the two sides of the main push link. When the main push link rotates, the balance bar can rotate together with the main push link.

[0010] The mechanical unlocking mechanism includes a cable swing arm, a second return spring, and a cable. The cable swing arm is rotatably connected to the base via the second return spring, and is also connected to the mechanical unlocking unit via the cable. When the handle body is opened to a set position, the user can pull the handle body to further rotate the main push linkage mechanism. The cable swing arm is located on the path of further rotation of the main push linkage mechanism and can be driven by the main push linkage mechanism to trigger the mechanical unlocking unit.

[0011] Furthermore, the balance bar is rotatably connected to the base via the first return spring.

[0012] Furthermore, when the user pulls the handle body to mechanically unlock, they need to overcome the elastic force of both the first and second reset springs simultaneously.

[0013] Furthermore, the balance bar is provided with a downwardly extending lever, and the cable swing arm is provided with an upwardly extending paddle. The main push linkage mechanism drives the cable swing arm by contacting the lever and the paddle.

[0014] Furthermore, the other end of the main push link forks to form a first swing arm and a second swing arm. The first swing arm and the second swing arm are rotatably connected to both ends of the handle body, respectively. A connecting groove is provided on the opposite surface of the first swing arm and the second swing arm, and both ends of the balance bar extend into the connecting groove and connect with it.

[0015] Furthermore, the main push link includes a first swing arm and a second swing arm located on both sides respectively. The two ends of the first swing arm and the second swing arm are rotatably connected to the base and the handle body respectively, and the first swing arm and the second swing arm are connected by the balance bar.

[0016] Furthermore, the cable is connected to one end of the cable swing arm.

[0017] Furthermore, the drive device is connected to the cam and can drive it to rotate. The cam can drive the main push rod to rotate by pressing against the surface of the main push rod during rotation.

[0018] Furthermore, an electronic unlocking unit is installed inside the handle body.

[0019] Furthermore, the side of the base extending toward the handle body also has a recessed hand grip space located below the handle body.

[0020] Furthermore, a cover is provided at the mounting points of the base and the handle body.

[0021] Beneficial effects: By connecting the balance bar to the main push rod with a width at one end, the rigid balance bar can reduce the deformation of the main push rod mechanism. This allows the first and second swing arms of the main push rod to move more synchronously when the cam drives the main push rod to rotate, thus smoothly opening the handle body. At the same time, by setting a mechanical unlocking mechanism, after the handle body is opened, the user can continue to pull the handle body to trigger the mechanical unlocking. The balance bar can also balance the pulling force, preventing the deformation of the main push rod mechanism due to pulling from affecting the mechanical unlocking. Attached Figure Description

[0027] Figure 6 This is a schematic diagram of the front structure of the present invention (with the handle body extended). Detailed Implementation

[0028] Example 1: As Figure 1 , Figure 2The illustration shows an electrically operated, semi-retractable handle, which includes a handle opening assembly for extending the handle body 4 from the base 1. The handle opening assembly includes a main push linkage mechanism, a linkage rod 3, a first return spring 6-1, a drive device (not shown), and a cam 5. The main push linkage mechanism includes a fork-shaped main push linkage 2, one end of which is connected to the base 1, and the other end is connected to both ends of the handle body 4, which are distributed laterally. The drive device provides power from one side of the main push linkage 2 to drive its rotation and extend the handle body 4. The main push linkage mechanism also includes a balance bar 6 with a certain rigidity. The balance bar 6 extends laterally and connects to both sides of the main push linkage 2 at both ends, giving the middle part of the main push linkage mechanism a certain rigidity. When the main push linkage 2 rotates, the balance bar 6 can rotate together with the main push linkage 2. With this structure, when the cam 5 drives the main push linkage 2 to rotate, the rigid balance bar 6 rotates synchronously. Its own rigidity can effectively constrain the relative deformation on both sides of the main push linkage 2, thereby preventing the handle body 4 from tilting when it extends, and ensuring its smooth extension.

[0029] The electrically operated semi-retractable handle also includes a mechanical unlocking mechanism. The mechanical unlocking mechanism is used to trigger the mechanical unlocking unit and includes a cable swing arm 7, a second return spring 8, and a cable (not shown in the figure). The cable swing arm 7 is rotatably connected to the base 1 through the second return spring 8. The cable swing arm 7 is also connected to the mechanical unlocking unit through the cable. When the handle body 4 is pushed out to the set position, the user can pull the handle body 4 to make the main push linkage mechanism rotate further. The cable swing arm 7 is located on the path of the main push linkage mechanism to rotate further and can be driven by the middle of the main push linkage mechanism to trigger the mechanical unlocking unit.

[0030] Users can unlock the car door using the electronic unlocking unit installed inside the handle body 4. After the handle body 4 is extended, the user can reach inside the handle body 4 to trigger the electronic unlocking unit. When the electronic unlocking unit malfunctions, mechanical unlocking can also be performed. The user can further pull the handle body 4 to drive the cable swing arm 7 to overcome the elastic force of the second spring 8 and rotate it. This can then trigger the mechanical unlocking unit to unlock the car door. Since mechanical unlocking requires overcoming the elastic forces of the first spring 6-1 and the second spring 8 simultaneously, this prevents the handle body 4 from being pulled out arbitrarily. After the car door is unlocked, the handle body 4 can be reset by the second spring 8. And when the drive device is reset, the handle body 4 can retract to the base under the action of the first spring 6-1. Meanwhile, it is worth mentioning that if the balance bar 6 is not used, the pull of the cable will be inconsistent at different positions of the handle body 4 due to the deformation of the main push link 2. This situation is more obvious when the cable is connected to the end of the cable swing arm 7, which will affect the user experience. This solution uses a balance bar 6 with a certain rigidity and makes the main push link mechanism have a rigid middle part to drive the cable swing arm 7 to rotate, so as to balance the pulling force and avoid the above situation.

[0031] Based on the above, in this scheme, the balance bar 6 can be rotatably connected to the base 1 via the first return spring 6-1; the balance bar 6 is provided with a downwardly extending lever 9, and the cable swing arm 7 is provided with an upwardly extending lever 7-1. The main push linkage mechanism can directly drive the cable swing arm 7 through the contact between the lever 9 and the lever 7-1 on the balance bar 6, or it can drive the cable swing arm 7 by setting the lever 9 on the main push linkage 2. Figures 1-3 The other end of the main push link 2 forks to form a first swing arm 2-1 and a second swing arm 2-2. The first swing arm 2-1 and the second swing arm 2-2 are rotatably connected to both ends of the handle body 4, respectively. A connecting groove 2-3 is provided on the opposite surface of the first swing arm 2-1 and the second swing arm 2-2. Both ends of the balance bar 6 extend into the connecting groove 2-3 and can slide along the connecting groove 2-3 and rotate relative to it.

[0032] In addition, such as Figure 5 , Figure 6 As shown, the side of the base 1 that extends toward the handle body 4 is also recessed to form a hand grip space 10. The hand grip space 10 is located below the handle body 4, making it convenient for the user to reach in and operate the handle body 4. A cover is provided at the mounting point of the base 1 and the handle body 4 to cover the gap.

[0033] Example 2: Figure 4As shown, the installation method of the balance bar 6 in this embodiment differs from that in embodiment one. The main push link 2 includes a first swing arm 2-1 and a second swing arm 2-2 located on both sides. The two ends of the first swing arm 2-1 and the second swing arm 2-2 are rotatably connected to the base 1 and the handle body 4, respectively. The first swing arm 2-1 and the second swing arm 2-2 are connected by the balance bar 6. With this coaxial installation method, it is not necessary to open the connecting groove 2-3. The balance bar 6 can be connected by opening connecting holes on the first swing arm 2-1 and the second swing arm 2-2. The balance bar 6 and the main push link 2 can be combined to form a fork-shaped main push link mechanism.

[0034] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The related content can also be applied to flip-up or other forms of electric handles. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
