Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0039] The embodiment of the present application discloses an electric upward-opening handle. Referring to Figure 1 and Figure 2 , the electric upward-opening handle includes a base 1, a handle 2 provided on the base 1, and a linkage device, and further includes a wire rope 7 connected to the door lock device of the door and a microswitch 8 provided inside the handle 2. The door lock device can be opened in two ways: mechanical opening and electric opening, which is prior art and will not be elaborated herein. The wire rope 7 is connected to the mechanical opening pivot of the door lock device, and the microswitch 8 is electrically connected to the electric opening pivot of the door lock device. The base 1 is arranged on the inner side of the door panel 9 and fixed by the connection assembly 11. Specifically, there are three groups of connection assemblies 11, two of which are located at the top of the base 1, and the other group is located at the bottom of the base 1. The three groups of connection assemblies 11 form a triangular fixed point position, thereby improving the stability of the base 1. The connection assembly 11 includes a nut provided on the door panel 9 and a bolt threadedly connected to the base 1. By cooperating the bolt with the nut, the base 1 can be firmly fixed on the door panel 9. An installation hole 91 (refer toFigure 7 ), one side of the base 1 close to the door panel 9 is provided with a receiving cavity which communicates with the mounting hole 91. The handle 2 is located in the receiving cavity and is rotatably connected to the base 1. By rotating the handle 2, the handle 2 pulls the cable 7 through the linkage device to mechanically unlock the door lock device; by pressing the micro switch 8 on the handle 2, the door lock is electrically unlocked.

[0040] When installing the power-up hinged handle on the door panel 9, only need to fixedly connect the base 1 equipped with the handle 2 and the linkage device to the door panel 9 through the connecting component 11, connect the cable 7 to the linkage device, and electrically connect the micro switch 8 to the electric hub of the door lock device, then the installation of the handle can be realized. And for the door sheet metal at the handle installation position, only need to open the mounting hole 91, without making a complex counterbore design, then the installation of the handle can be realized. And this handle is a hidden handle with both electric unlocking and mechanical unlocking, thus effectively reducing the production difficulty of the door with a hidden handle with both electric unlocking and mechanical unlocking.

[0041] Specifically, referring to Figure 2 , the linkage device includes a first rocker arm 3 and a first reset member 4. The first rocker arm 3 is welded and fixed to the inner side of the handle 2. The first rocker arm 3 is arc-shaped and the concave side faces the outside of the handle 2. The handle 2 is rotatably connected to the base 1 through the first rocker arm 3. A limiting groove 13 is provided on the base 1. The first rocker arm 3 extends out of the receiving cavity of the base 1 through the limiting groove 13, and the limiting groove 13 limits the first rocker arm 3. In order to improve the stability of the handle 2, there are two first rocker arms 3, and they are arranged at intervals along the length direction of the handle 2. In this embodiment, the two first rocker arms 3 are symmetrically arranged at both ends of the handle 2. The first reset member 4 includes a pin shaft 41 and a first torsion spring 42. The pin shaft 41 is a round rod with a thread at one end. The pin shaft 41 is erected on the top of the base 1 and is fixedly connected to the base 1 by threading. The pin shaft 41 penetrates through the end of the first rocker arm 3 away from the handle 2, and the first rocker arm 3 is rotatably connected to the pin shaft 41. The first torsion spring 42 is sleeved on the pin shaft 41, and the torsion ends are respectively connected to the base 1 and the first rocker arm 3.

[0042] In order to increase the torsion of the first torsion spring 42 and reduce the possibility of accidental opening of the handle 2, in this embodiment, the first torsion spring 42 adopts a double torsion spring. A support column 12 is integrally formed on the base 1. The two ends of the double torsion spring are respectively fixedly connected to two first force arms, and the middle of the double torsion spring is bridged and lapped on the side of the support column 12 away from the first torsion spring 42, so as to realize an increase in the torque of the first rocker arm 3 to return to its original position. As an alternative embodiment, the first torsion spring 42 can also adopt two separate torsion springs, and the two separate torsion springs are respectively connected to the two first rocker arms 3 and the base 1.

[0043] Referring to Figure 3, The linkage device further includes a second rocker arm 5 and a second reset member 6. The second rocker arm 5 includes a shaft rod 51, a driving arm 52, and a pull rod 53. The shaft rod 51 is rotatably connected to the base 1 through a bearing. The driving arm 52 and the pull rod 53 are fixedly welded to the side wall of the shaft rod 51. The driving arm 52 is located on the side of the pull rod 53 close to the first rocker arm 3. The driving arm 52 is located on the outer side of the first rocker arm 3 close to the handle 2 and abuts against the first rocker arm 3. The driving arm 52 is arc-shaped and the concave side faces the first rocker arm 3. The pull rod 53 is located on the side of the shaft rod 51 facing the back side of the handle 2. A clamping groove is provided at one end of the pull rod 53 away from the shaft rod 51. A clamping head is fixed at the end of the wire 7. By clamping the clamping head with the clamping groove, the wire 7 can be fixedly connected to the pull rod 53, thereby realizing the connection between the wire 7 and the second rocker arm 5. The second reset member 6 is a second torsion spring, and the torsion ends of the second torsion spring are respectively fixedly connected to the base 1 and the pull rod 53.

[0044] When the door needs to be opened mechanically, rotate the handle 2. The handle 2 drives the first rocker arm 3 to rotate. The first rocker arm 3 pushes the second rocker arm 5 to rotate, so that the second rocker arm 5 pulls the wire 7, and the door lock device can be opened mechanically. Release the handle 2, and the first rocker arm 3 and the second rocker arm 5 are reset under the action of the first reset member 4 and the second reset member 6, so that the handle 2 is completely retracted into the receiving groove, maintaining the hidden handle state. The entire linkage device is simple, the structure layout is relatively compact, and it is convenient to be installed on the base 1, thus facilitating the installation of the handle.

[0045] Refer to Figure 4 , The handle 2 includes a housing 21, a trigger soft pad 22, and an end cover 23. The housing 21 opens downward. The trigger soft pad 22 is made of an elastic material such as rubber or silica gel. The trigger soft pad 22 is located inside the housing 21 and is fixedly bonded to the housing 21, or can be fixedly clamped to the housing 21. In this embodiment, the trigger soft pad 22 is fixedly bonded to the housing 21. The end cover 23 is located outside the housing 21. An installation cavity is formed among the housing 21, the trigger soft pad 22, and the end cover 23. The micro switch 8 is located in the installation cavity. By pressing the trigger soft pad 22, the trigger soft pad 22 deforms to trigger the micro switch, and the door can be opened electrically.

[0046] In order to improve the sensitivity of the electric opening method, a trigger block 24 is provided between the trigger soft pad 22 and the micro switch 8. The length direction of the trigger block 24 is the same as the length direction of the housing 21. The trigger block 24 is rotatably connected to the housing 21. The rotation axis is parallel to the length direction of the housing 21. One side of the trigger block 24 abuts against the trigger soft pad 22, and the other side abuts against the micro switch 8. Two micro switches 8 are arranged at intervals along the length direction of the handle 2. By providing the trigger block 24 and two micro switches 8, the sensitivity of the handle to electrically open the door can be greatly improved, and the possibility that the micro switch 8 does not respond after the user presses the trigger soft pad 22 can be reduced, thereby improving the convenience of use.

[0047] Referring to Figure 5 and Figure 6 When it is necessary to open the car door electrically, put your hand into the receiving cavity of the handle 2, press the trigger cushion 22 with your finger, the trigger cushion 22 deforms and pushes the trigger block 24 to rotate, and the trigger block 24 presses the micro switch 8, so as to realize the electric opening of the car door; When it is necessary to open the car door mechanically, put your hand into the receiving cavity and pull the handle 2 outward forcefully, so that the first rocker arm 3 rotates against the torsion force of the first torsion spring 42 and pushes the second rocker arm 5 to rotate, so that the second rocker arm 5 pulls the cable 7, thus realizing the mechanical opening of the car door. Both the electric opening and the mechanical opening can be realized through a single handle 2. The handle 2 and the linkage device are both installed on the base 1, which not only improves the convenience of user use, but also reduces the difficulty of car door production.

[0048] Referring to Figures 7 - 9 , an installation hole 91 is provided near the base 1 on the door panel 9, and the base 1 is installed and fixed from the inner side of the door panel 9, thus greatly reducing the production difficulty of the door panel 9 and improving the convenience of handle installation. In order to improve the strength of the door panel 9 and facilitate the installation of the handle, a reinforcing plate 92 is fixed to the inner side of the door panel 9 by bolts, and the base 1 is fixedly connected to the reinforcing plate 92.
