[0036] Reference Figure 1 and Figure 2 As shown, a concealed door handle assembly provided in an embodiment of the present utility model includes a base 100, a handle body 200, and a back cover 300.

[0037] Reference Figure 2 As shown, the base 100 has a receiving cavity 110 and an opening 120 communicating with the receiving cavity 110. The handle body 200 is installed in the receiving cavity 110 through the opening 120. The rear cover 300 is connected to the base 100 and is located on the side of the base 100 opposite to the opening 120. (Refer to...) Figure 8 and Figure 9 As shown, the handle body 200 is provided with a first guide boss 210, as shown in the figure. Figure 10 and Figure 11 As shown, the rear cover 300 is provided with a second guide boss 320. After assembling the entire concealed door handle assembly, refer to... Figure 3 As shown, the second guide boss 320 is located on one side of the first guide boss 210 and can abut against the first guide boss 210. The second guide boss 320 can extend along a specific rotation trajectory of the handle body 200, thereby limiting the handle body 200. When the user needs to open the car door in an emergency, the handle body 200 will not automatically pop out (a malfunction may have occurred). In this case, the user needs to press... Figure 4 Press the end of the handle body 200 in the direction of the arrow, causing the other end of the handle body 200 to lift up. During the lifting process, the first guide boss 210 will gradually move closer to the second guide boss 320. Eventually, the second guide boss 320 will abut against the first guide boss 210, which can prevent the handle body 200 from moving along the length of the base 100. The handle body 200 is less likely to deviate laterally, which can prevent the end of the handle body 200 away from the user's pressing position from scratching the door sheet metal. After pressing out the handle body 200, refer to... Figure 6 Pulling out the handle body 200 in the direction of the arrow unlocks the car door. The length of the base 100 can be referenced. Figure 1 As indicated by the arrow in the diagram, after the entire handle assembly is installed, the length of the base 100 is generally horizontal.

[0038] Reference Figure 1 and Figure 3 As shown, when the handle body 200 is in the hidden position, the handle body 200 is located in the receiving cavity 110. There is a certain distance between the first guide boss 210 and the second guide boss 320, so as to avoid the second guide boss 320 from obstructing the handle body 200 from extending normally in the direction perpendicular to the opening 120.

[0039] Reference Figure 8 As shown, in some embodiments, the handle body 200 has a first handle portion 220 and a second handle portion 230 on the side facing the rear cover 300. The first handle portion 220 is a hollow structure, and the first handle portion 220 and the second handle portion 230 are inserted into the receiving cavity 110 of the base 100. The first handle portion 220 and the second handle portion 230 serve as a connecting structure. (Refer to...) Figure 9 As shown, a first guide boss 210 is formed on the inner wall of the first shank 220, and a second guide boss 320 extends into the first shank 220. (Refer to...) Figure 2 and Figure 3 As shown, the concealed door handle assembly also includes a drive arm 400, an unlocking cam 410, a driven arm 430, and an unlocking arm 440 disposed within the receiving cavity 110. The drive arm 400 has a certain elasticity and can deform. The drive arm 400 is approximately V-shaped. One end of the drive arm 400 is rotatably connected to the base 100, and the other end of the drive arm 400 extends into the first handle 220 and is rotatably connected to the first handle 220. The unlocking cam 410 is rotatably connected to the base 100 and has a fan-shaped cam structure. The unlocking arm 440 controls the unlocking of the door. The unlocking arm 440 is connected to the unlocking cam 410. The unlocking cam 410 has an arc-shaped hole 420. One end of the driven arm 430 is hinged to the arc-shaped hole 420 and can slide along the arc-shaped hole 420. The other end of the driven arm 430 is rotatably connected to the second handle 230.

[0040] like Figure 4 As shown, when the user presses the end of the handle body 200 in the direction of the arrow, the handle body 200 rotates around the connection end between the drive arm 400 and the handle body 200, causing the other end of the handle body 200 to lift up or pop out, exposing the handle body 200 to the outside of the receiving cavity 110. Then, as... Figure 6 As shown, the user pulls the handle body 200 parallel out in the direction of the arrow, and the handle body 200 is pulled to a horizontal position. Finally, as... Figure 7As shown, when the user pulls the other end of the handle body 200 in the direction of the arrow, the handle body 200 is at the maximum unlocking stroke position. During the extension process, the second handle 230 of the handle body 200 also pulls the driven arm 430 to rotate, and the driven arm 430 also pulls the unlocking cam 410 to rotate. The unlocking cam 410 simultaneously drives the unlocking arm 440 to rotate, thereby completing the unlocking of the car door.

[0041] It should be noted that, Figure 4 , Figure 6 and Figure 7 During the entire movement of the handle body 200, the first guide boss 210 and the second guide boss 320 remain in contact. The second guide boss 320 can restrict the movement of one end of the first guide boss 210 in the horizontal direction, thereby restricting the misalignment of one end (Y direction) of the handle body 200 in the horizontal direction. This can prevent the handle body 200 from scratching the door sheet metal.

[0042] In this embodiment, the second guide boss 320 extends into the first handle portion 220, which can make full use of the internal space of the first handle portion 220 and reduce the size of the entire handle assembly. The drive arm 400, unlocking cam 410, driven arm 430 and other structures are connected to the handle body 200, so that the handle body 200 can move flexibly and the user can more easily push out the handle body 200 to unlock the car door.

[0043] Reference Figure 9 and Figure 11 As shown, in some embodiments, the first guide boss 210 is located on two opposing inner walls of the first handle portion 220. The rear cover 300 has an extending protrusion 310 on the side facing the handle body 200, extending into the handle body 200. Second guide bosses 320 are formed on opposite sides of the extending protrusion 310, and the extending protrusion 310 and the second guide boss 320 together form a generally U-shaped structure. The two second guide bosses 320 respectively mate with the two first guide bosses 210. This improves the guiding stability of the handle body 200, and the extending protrusion 310 has greater structural strength.

[0044] Reference Figure 5As shown, in some embodiments, the length of the second guide boss 320 is greater than the length of the first guide boss 210. The second guide boss 320 has an arc-shaped wall 330, and the first guide boss 210 can abut against the arc-shaped wall 330. When the handle body 200 rotates around the connection end between the drive arm 400 and the handle body 200, the first guide boss 210 slides along the arc-shaped wall 330. It can also be understood that the arc-shaped wall 330 is set along the rotation trajectory of the handle body 200, restricting the handle body 200 to rotate only along the arc-shaped wall 330, thus preventing the other end of the handle body 200 from scraping against the door sheet metal. Furthermore, with this arrangement, the first guide boss 210 and the second guide boss 320 form point contact, resulting in lower friction and smoother rotation of the handle body 200, which is beneficial for the other end of the handle body 200 to lift up.

[0045] When the handle body 200 is from Figure 6 Reset the state to Figure 3 When in the state, the first guide boss 210 also slides against the arc wall 330, which restricts the rotation trajectory of the handle body 200, so that the handle body 200 will not scratch the door sheet metal during the reset process.

[0046] Reference Figure 11 As shown, in some embodiments, the sidewall of the second guide boss 320 is provided with a reinforcing rib 340. This can enhance the structural strength. The reinforcing rib 340 can be configured as a triangular structure, which provides greater structural strength.

[0047] Reference Figure 2 As shown, in some embodiments, the concealed door handle assembly further includes a frame 450 and a seal 460. The frame 450 is installed in the opening 120 and surrounds the handle body 200. The frame 450 is used to install the seal 460. The seal 460 is fastened to the frame 450 and surrounds the handle body 200. The seal 460 can play a sealing role, preventing rainwater or dust from entering the receiving cavity 110.
