A mounting seat 103 is disposed on the inner surface of the door sheet metal 1 corresponding to the mounting area 101. The mounting seat 103 is used to constrain the type 1 handle 4 or the type 2 handle 5 to the outer surface of the door sheet metal 1. The type 1 handle 4 or the type 2 handle 5 is configured to match the outer surface of the door sheet metal 1 to the mounting seat 103, and allows the type 1 handle 4 or the type 2 handle 5 to perform an unlocking action with respect to the mounting seat 103.

[0047] Among them, the second type of handle 5 is a hidden handle, which can extend and retract within the installation area 101. When the first type of handle 4 is a regular handle, it can swing within the installation area 101. This allows for the simultaneous compatibility of regular door handles and hidden door handles on the door sheet metal 1, reducing the R&D costs of new door sheet metal 1 and reducing the mold opening costs, thereby significantly reducing manufacturing costs.

[0048] Example 2

[0049] In this embodiment, a type II handle 5 is used. The type II handle 5 is a concealed handle, and the transmission structure 3 in this embodiment is adapted to the concealed handle.

[0050] like Figure 7 , Figure 8 , Figure 9As shown, specifically, the back of the door panel 1 is provided with a mounting seat 103, the transmission structure 2 is arranged on the mounting seat 103, the transmission structure 2 includes a first rotating arm 104 and a second rotating arm 105 arranged on the mounting seat 103, a driving rod 106 driving the first rotating arm 104 and the second rotating arm 105 to rotate, and a driving unit 107 driving the driving rod 106 to act, the first rotating arm 104 and the second rotating arm 105 are respectively connected to the connecting portions 3 at two ends of the second type handle 5, the driving unit 107 drives the driving rod 106 to move, the driving rod 106 synchronously drives the first rotating arm 104 and the second rotating arm 105 to rotate, and the first rotating arm 104 and the second rotating arm 105 synchronously drive the second type handle 5 to extend and retract from both sides, thereby improving the stability of the second type handle 5 during the extension and retraction process.

[0051] As shown in the drawings, Figure 8 Further, the driving rod 106 is formed with a pulling groove 108, and the first rotating arm 104 and the second rotating arm 105 are formed with a pulling protrusion 109, the pulling protrusion 109 is placed in the pulling groove 108, and as the driving rod 106 moves, the pulling groove 108 drives the pulling protrusion 109 to move, thereby driving the first rotating arm 104 and the second rotating arm 105 to rotate.

[0052] As shown in the drawings, Figure 9 , Figure 10 Further explanation about the connection of the second type handle 5 with the first rotating arm 104 and the second rotating arm 105 in the embodiment, the connecting portion 3 is formed with a connecting groove 201 for placing the connecting ends of the first rotating arm 104 and the second rotating arm 105, and the bottom of the connecting portion 3 is formed with a first insertion hole 205 for inserting a pin shaft 207, and the first rotating arm 104 and the second rotating arm 105 are formed with a second insertion hole 206 for inserting the pin shaft 207, during the installation of the second type handle 5, the connecting ends of the first rotating arm 104 and the second rotating arm 105 can be placed in the connecting groove 201, and the pin shaft 207 is inserted from the bottom of the connecting portion 3, so that the pin shaft 207 passes through the first insertion hole 205 and the second insertion hole 206 of the first rotating arm 104 and the second rotating arm 105, thereby connecting the first rotating arm 104 and the second rotating arm 105 with the connecting portion 3 of the second type handle 5, so as to realize the extension and retraction of the second type handle 5 along with the rotation of the first rotating arm 104 and the second rotating arm 105, thereby improving the stability of the operation of the hidden handle.

[0053] Further, the first rotating arm 104 and the second rotating arm 105 are provided with a connecting block 801, the connecting block 801 is connected with the connecting part 3, the second insertion hole 206 is formed on the connecting block 801, and the first rotating arm 104 and the second rotating arm 105 are provided with a sliding rod 802, the connecting block 801 is provided with a sliding groove 803 for placing the sliding rod 802, and the connecting block is arranged on the first rotating arm 104 and the second rotating arm 105, and the connecting block 801 will extend out of the insertion slot 102 along with the rotation of the first rotating arm 104 and the second rotating arm 105, which is more convenient for connecting with the handle, and the sliding rod 802 will move along the sliding groove 803 in the rotation process of the first rotating arm 104 and the second rotating arm 105, thereby ensuring the stability of the extension and retraction of the hidden handle.

[0054] As shown in Figure 5 , Figure 6 , as a further explanation of the connection between the mounting seat 103 and the door panel 1 in the embodiment, the mounting seat 103 is first arranged at the back of the door panel 1, and since the mounting seat 103 is provided with the first limiting block 501 and the second limiting block 502, when the mounting seat 103 is arranged at the back of the door panel 1, the first limiting block 501 is placed into the positioning groove 503 of the door panel 1 to limit the movement of the mounting seat 103 along the X-axis and the Z-axis, and the second limiting block 502 is supported at the back of the mounting area 101 to limit the movement of the mounting seat 103 along the Y-axis, thereby limiting the mounting seat 103 from three directions of X, Y and Z, and ensuring the stability of the mounting seat 103 during the mounting process.

[0055] Then the mounting seat 103 is fixed by screws, and since the mounting seat 103 is arranged at the back of the door panel 1 during the mounting process, the screw hole 202 is placed into the through hole 203, and the mounting seat 103 is fixed on the door panel 1 by the screws, and the shielding piece 204 is inserted into the insertion slot 102, so that the shielding piece 204 shields the screws, thereby greatly improving the appearance.

[0056] As a preferred, the bottom of the second handle 5 forms a groove 404 for placing the shielding piece 204, and when the second handle 5 is retracted into the mounting area 101, the shielding piece 204 can be placed into the groove 404 to avoid interference.

[0057] As shown in Figure 8As shown, a further explanation of the usage method of the sliding valve 301 in this embodiment is provided. The mounting base 103 is provided with a sliding valve 301, and the sliding valve 301 is provided with a screw 302 to drive its movement. A pulling part 303 is formed on the sliding valve 301, and a pulling post 304 is provided on the drive rod 106. During the installation of the handle, since the drive unit 107 is not powered and cannot drive the drive shaft to move, the screw 302 can be manually rotated to move the sliding valve 301, thereby causing the pulling part 303 on the sliding valve 301 to pull the pulling post 304 to move, thereby causing the drive rod 106 to move, and driving the first rotating arm 104 and the second rotating arm 105 to rotate to the maximum angle in the handle extension direction and partially extend out of the slot 102, which makes it easier for the first rotating arm 104 and the second rotating arm 105 to connect with the second type of handle 5.

[0058] Furthermore, the screw 302 is threadedly connected to the sliding valve 301, and a mounting groove 405 is formed on the mounting base 103 for the head of the screw 302 to be inserted, so that it can rotate on the mounting base 103.

One end of the elastic element 505 abuts against the mounting base 103, and the other end abuts against the first rotating arm 104 and the second rotating arm 105. The elastic element 505 acts on the first rotating arm 104 and the second rotating arm 105 so that they can reset themselves.

[0061] Furthermore, a limiting part 506 is formed on the mounting base 103. The first rotating arm 104 and the second rotating arm 105 are rotatably mounted in the limiting part 506. When the type II handle 5 is in the retracted state, the first rotating arm 104 and the second rotating arm 105 abut against the limiting part 506. The elastic element 505 acts on the first rotating arm 104 and the second rotating arm 105 to keep them in a rotating state. The limiting part 506 limits them to ensure that the type II handle 5 is retracted and completely inserted into the mounting area 101.

[0062] As preferred, the first rotating arm 104 is provided with a guide groove 601, and the mounting base 103 is provided with a guide protrusion 602, which is inserted into the guide groove 601, thereby improving the stability during the rotation of the first rotating arm 104.
