Any change or adjustment of their relative relationships is deemed to be within the scope of the present invention, provided that there is no substantial change in the technical content.

[0023] Please refer to Figures 1 to 14. The present invention provides an inward-tilting door handle, a door, and a vehicle to solve the problem of the handle being easily thrown out of the vehicle and damaged by collision.

[0024] 1 and 2, the inward-tilting door handle according to the present invention includes a handle base 100 having a handle mounting groove 110, a handle 200 mounted in the handle mounting groove 110 and rotatably connected to the handle base 100, a link mechanism 300, and a linear drive 400. The linear drive 400 is disposed on the handle base 100 and drives the rotation of the handle 200. The link mechanism 300 is rotatably mounted on the handle base 100, and a drive input end of the link mechanism 300 is hingedly connected to a linear movement drive end of the linear drive 400, and a motion output end of the link mechanism 300 is slidably connected to the handle 200. When the door is closed, the handle 200 covers the handle mounting groove 110 and is flush with the door outer panel. When the linear drive 400 is activated, the linear drive 400 rotates the handle 200, which covers the handle mounting groove 110, toward the inside of the handle base 100 via the link mechanism 300, exposing the handle mounting groove.

[0025] 2 and 3. In one embodiment, the linear drive 400 includes an electric actuator 410 and a push rod 420 attached to the output end of the electric actuator 410, the output power of the electric actuator 410 being a linear driving force, and the push rod 420 is driven by the electric actuator 410 to perform linear reciprocating motion. In this embodiment, the handle base 100 is a box-shaped cabinet surrounded by a bottom plate and side plates arranged around the bottom plate, and one side of the box-shaped cabinet is provided with a first receiving cavity 120 for mounting the electric actuator and a slideway 130 for sliding the push rod 420, and the other side is provided with a second receiving cavity 140 for mounting the link mechanism 300 and the handle 200. The electric actuator 410 is mounted in the first receiving cavity 120 by a fastener, and the slideway 130 is provided at the output end of the electric actuator 410. The slideway 130 is provided along the lateral direction of the handle base 100. The push rod 420 moves linearly back and forth within the slideway 130 under the action of the electric actuator 410. The link mechanism 300 is provided in the second receiving cavity 140 at a position corresponding to the slideway 130. The linear movement of the push rod 420 can rotate the link mechanism 300 to flip the handle 200 into the handle base 100. The electric actuator 410 in this embodiment can employ a conventional actuator assembly known in the art, and its specific structure will not be described here. In other embodiments, a linear drive with another conventional structure, such as a drive motor and a turbine worm drive assembly cooperating with the drive motor, can be employed. The turbine worm drive assembly can convert the rotational motion of the drive motor into linear motion.

[0026] Please refer to Figures 5 to 7. The directions of the arrows in Figure 6 indicate the rotation directions of the link mechanism and the handle, respectively. In one embodiment, the link mechanism 300 includes a first link 310 and a second link 320, which are fixedly connected to each other to form a V-shaped pivot arm, and an intersection of the first link 310 and the second link 320 is rotatably attached to the handle base 100. In another embodiment, the first link 310 and the second link 320 may be of an integral structure. One end of first link 310 away from the intersection between first link 310 and second link 320 serves as the operating output end of link mechanism 300, and the operating output end is slidably connected to handle 200. For example, first link 310 has a protrusion 311 on one side facing handle 200, with an engaging groove 312 formed inside protrusion 311, and a first connecting seat 210 cooperating with engaging groove 312 provided at a corresponding position on handle 200. Protrusion 311 may be two protruding blocks arranged opposite each other, with the gap between the two protruding blocks forming engaging groove 312, or protrusion 311 may be an integral structure with engaging groove 312 formed in the center of the protrusion. Here, the manner of forming engaging groove 312 is not limited. The first connecting seat 210 protrudes from the inner surface of the handle 200. For example, the first connecting seat 210 comprises two spaced apart seat bodies 211 and a cross beam 212 connecting the two seat bodies 211. Preferably, the seat bodies 211 have a triangular prism structure, the cross beam 212 is suspended from the base 211, and both ends of the cross beam 212 are connected to the two seat bodies 211 respectively. The first connecting seat 210 and the handle 200 may be an integral structure or a separate connecting structure. The cross beam 212 is always in the engagement groove. 312 Since the longitudinal size of the cross beam 212 is smaller than the size of the opening of the engagement groove 312, the cross beam 212 and the engagement groove 212 form a sliding pair, and as the link mechanism 310 rotates, the first link 310 slides along the cross beam 212, at the same time flipping the handle 200 inward.

[0027] Please refer to Figures 2, 5, and 8 to 10. The arrow in Figure 10 indicates the direction of rotation from when the handle is closed to when it is opened. One end of second link 320, which is away from the intersection of first link 310 and second link 320, serves as the power input end of link mechanism 300, and is hingedly connected to push rod 420. For example, one end of push rod 420 is fixedly connected to the output end of electric actuator 410, and the other end is provided with an engagement groove, and second link 320 is inserted into the engagement groove and hingedly connected to push rod 420 by a pin shaft. The electric actuator 410 drives the push rod 420 to move linearly forward (away from the electric actuator 410), and the push rod 420 rotates the link mechanism 300 counterclockwise. As the link mechanism 300 rotates, the first link 310 slides along the cross beam 212 of the first connecting seat 210, and at the same time pushes the handle 200 downward, flipping the handle 200 into the handle base 100 and converting the handle 200 from the closed position to the open position. Similarly, the electric actuator 410 drives the push rod 420 to move linearly backward (toward the electric actuator 410), and the push rod 420 rotates the link mechanism 300 clockwise. As the link mechanism 300 rotates, the first link 310 slides in the opposite direction along the cross beam 212, and at the same time pushes the handle 200 upward, returning the handle 200 from the open position to the closed position. Link mechanism By adopting a V-shaped swivel arm structure, 300 can ensure normal rotational movement of the link mechanism, and also transmits the linear movement of the push rod 420 to the handle 200, causing the handle 200 to flip back into the handle base and return to be flush with the door outer panel.

[0028] Please refer to Figures 3 to 5. In one embodiment, the link mechanism 300 is rotatably connected to the handle base 100 by a first rotation shaft 350.

Preferably, a torsion spring is further disposed at the connection point between the link mechanism 300 and the handle base 100, where the torsion spring is referred to as a first torsion spring 360, and the first torsion spring 360 is attached between the first bush 330 and the second bush 340, and both ends of the first torsion spring 360 are connected to the handle base 100 and the link mechanism 300, respectively. For example, a first mounting groove 331 is provided on the side wall of the first bush 330, a bush fixing seat 151 is provided on the outer periphery of the third bush 150, and a second mounting groove 152 is provided on the side wall of the bush fixing seat 151, the first torsion spring 360 is accommodated in the space between the first bush 330 and the second bush 340 and is fitted into the second bush 340, and both ends of the first torsion spring 360 are respectively connected to the first mounting groove 331 and is housed in the second mounting groove 152. By providing the first torsion spring 360, the link mechanism always maintains elasticity and tends to return to its initial position.

In one embodiment, the handle mounting groove 110 is provided on the bottom plate of the handle base 100 and is located above the link mechanism 300, with the inner cabinet of the handle mounting groove 110 providing clearance for the handle 200 to be turned over. The handle 200 is mounted in the handle mounting groove 110 and rotatably connected to the handle base 100 by a second rotation shaft 170. Specifically, a handle mounting seat 160 is provided in a position corresponding to the lower side of the handle mounting groove 110 of the handle base 100, and the handle mounting seat 160 includes end and middle portions, and the end and middle portions are provided with through holes for the rotation shaft to pass through.

One end of the arch-shaped structure is fixed to the handle 200, and the other end has a through-hole for a rotating shaft to pass through. The second rotating shaft 170 passes through the through-holes on the handle mounting seat 160 and the second connecting seat 220 to connect them. When the link mechanism 300 is driven by the push rod 420 to rotate around the first rotating shaft 350, it rotates the handle 200 around the second rotating shaft 170, causing the handle 200 to rotate inward or return to its initial position from the rotated position. Preferably, a seal structure 230 is provided between the handle 200 and the handle mounting groove 110. The seal structure 230 may be a seal ring provided along the circumferential direction of the handle mounting groove 110. When the handle 200 is closed, the seal ring can seal the gap between the handle base 100 and the handle 200.
