[0031] Unlocking arm 300, groove 310, driven cam 320, hook lock 330;

[0032] Frame 400, extension 410, U-shaped bayonet 420, reinforcing rib 430, cantilever buckle 440, first positioning protrusion 450, annular boss 460, second positioning protrusion 470;

[0033] Seal 500, annular groove 510, second positioning groove 520. Detailed Implementation

[0034] Reference Figure 1 As shown, a concealed door handle assembly provided in this embodiment of the present utility model includes a base 100, a handle body 200, an unlocking arm 300, a frame 400, and a sealing element 500.

[0035] Reference Figure 1 and Figure 2 As shown, the base 100 has a receiving cavity 110 and an opening 120 communicating with the receiving cavity 110, and the handle body 200 is installed in the receiving cavity 110 through the opening 120. Figure 1In the middle, the handle body 200 is in a hidden position. The outer side of the handle body 200 fits against the base 100 and does not protrude from the outside. When it is necessary to open the door, the handle body 200 will automatically extend upwards out of the receiving cavity 110 for the user to hold and pull. The user can unlock the door by pulling the handle body 200.

[0036] Reference Figure 5 and Figure 6 As shown, the base 100 has a mounting hole 150 on its side that communicates with the receiving cavity 110. The mounting hole 150 is used to mount the unlocking arm 300. The unlocking arm 300 passes through the mounting hole 150 and connects to the handle body 200. Simultaneously, a portion of the unlocking arm 300 is located within the receiving cavity 110. When the user pulls the handle body 200, it causes the unlocking arm 300 to rotate, thus unlocking the vehicle door. (Refer to...) Figure 3 and Figure 7 As shown, the outer peripheral wall of the unlocking arm 300 has a groove 310 arranged circumferentially along the unlocking arm 300, and the groove 310 is annular. The retaining frame 400 is installed at the opening 120 and arranged circumferentially along the handle body 200, surrounding the handle body 200, and has an extension 410 on the side of the retaining frame 400 facing the base 100. (Refer to...) Figure 3 and Figure 4 As shown, at the opening 120, the base 100 has a slot 130 communicating with the receiving cavity 110. The slot 130 allows the extension 410 of the card frame 400 to be inserted, and the groove 310 of the unlocking arm 300 is located exactly within the slot 130. During assembly, the unlocking arm 300 is installed first, and then the card frame 400 and the sealing element 500 are assembled. The extension 410 is inserted into the slot 130 and engages with the groove 310 of the unlocking arm 300, thereby restricting the axial movement of the unlocking arm 300. This eliminates the need for screws on the unlocking arm 300, saving the screw-driving process. The structure is stable, installation is simple, and the manufacturing cost of the push-type door handle can be reduced.

[0037] Additionally, refer to Figure 2 and Figure 3 As shown, the sealing element 500 is fastened to the frame 400 and surrounds the outer periphery of the handle body 200. When the handle body 200 is in the hidden position, the sealing element 500 surrounds the handle body 200, thereby sealing the gap between the sealing element 500 and the handle body 200, thus providing a sealing effect, making it difficult for external rainwater or dust to enter the interior of the base 100.

[0038] It should be noted that the card frame 400 can be made of plastic and can be manufactured by one-piece injection molding process, which makes it easy to process the structure of the extension 410, and the seal 500 can be made of sealant.

[0039] In some embodiments, refer to Figure 8 As shown, the extension 410 has a U-shaped bayonet 420, and the inner wall of the U-shaped bayonet 420 is inserted into the groove 310. This arrangement increases the contact area between the extension 410 and the groove 310, ensuring a better locking effect.

[0040] In some embodiments, refer to Figure 5 and Figure 8 As shown, the card frame 400 is provided with a cantilever buckle 440, and the base 100 is provided with a card slot 140. The cantilever buckle 440 and the card slot 140 are engaged. This facilitates the engagement and assembly of the card frame 400 and the base 100.

[0041] In some embodiments, refer to Figure 5 and Figure 8 As shown, the card frame 400 is provided with a first positioning protrusion 450, and the base 100 is provided with a first positioning groove 160 that mates with the first positioning protrusion 450. The first positioning protrusion 450 is inserted into the first positioning groove 160, which can play a positioning role and facilitate the alignment of the cantilever buckle 440 with the card groove 140.

[0042] In some embodiments, refer to Figure 8 As shown, the surface of the extension 410 is provided with reinforcing ribs 430. The reinforcing ribs 430 can improve the structural strength of the extension 410.

[0043] In some embodiments, refer to Figure 8 As shown, the sealing element 500 and the retaining frame 400 are connected by a snap-fit. The retaining frame 400 has an annular boss 460 on the side facing the sealing element 500. The annular boss 460 is arranged circumferentially along the handle body 200, and the handle body 200 is located on the inner circumference of the annular boss 460. The sealing element 500 has an annular groove 510 on the side facing the retaining frame 400 that mates with the annular boss 460. When the sealing element 500 overlaps the retaining frame 400, the annular boss 460 and the annular groove 510 are tightly engaged, sealing the gap between the sealing element 500 and the retaining frame 400 and improving the sealing effect.

[0044] In some embodiments, refer to Figure 8 As shown, the outer peripheral wall of the annular boss 460 is provided with a second positioning protrusion 470, and the inner wall of the annular groove 510 is provided with a second positioning groove 520 that mates with the second positioning protrusion 470. When the sealing member 500 is snapped onto the annular boss 460 of the frame 400 from top to bottom, the second positioning protrusion 470 is inserted into the second positioning groove 520, thereby playing a positioning role and preventing the sealing member 500 from shifting position during installation.

[0045] This utility model also provides a car door, which includes the concealed door handle assembly described in the above embodiments.

[0046] This utility model also provides a vehicle, which includes the door of the above embodiment.
