[0045] Example 1

[0046] A new type of hidden electric opening handle structure for automobiles, such as Figures 1 to 6 As shown, it includes a base assembly for installation on a vehicle door and a handle assembly installed on the base assembly, the handle assembly can be flipped between an upward flip-open position and a closed position, when the handle assembly is in the closed position, the handle assembly covers the base assembly, and the outer surface of the handle assembly is flush with the outer surface of the vehicle door, when the handle assembly is in the upward flip-open position, the handle assembly is unfolded to the outer side of the vehicle door;

[0047] The base assembly includes a base 201 and a frame 202. The base 201 is arranged on the door panel. The frame 202 is hinged to the base through a pin 204. The frame can be turned up and down around the hinge of the pin. A torsion spring 205 is arranged between the frame and the base. The torsion spring 205 is sleeved on the pin. The torsion spring 205 is used to reset the frame 202. The handle assembly is connected to the frame.

[0048] An actuator driving mechanism and a delay mechanism are provided on the base, and the actuator of the actuator driving mechanism is used to connect with the door controller; the actuator driving mechanism includes a cam 212 and an actuator 213, and the output end of the actuator 213 is connected with a first pin shaft 204, the first pin shaft 204 is arranged on the base, the cam 212 is sleeved on the first pin shaft 204, the cam is arranged on one side of the frame, the cam is in contact with the frame, the delay mechanism is arranged on one side of the frame, connected with the frame, and the delay mechanism is connected with a pull wire or a pull rod.

[0049] When the car controller detects that the key is close to the door or receives a signal source, the actuator 213 drives the first pin shaft 204 to rotate, and the cam rotates with the first pin shaft. The cam drives the frame and the handle assembly to flip to the pre-door opening position. The pre-door opening position of the handle assembly is between the closed position and the upward opening position, which is convenient for a person to insert a hand under the handle assembly. Due to the existence of the delay mechanism, the pull rod or pull wire will not flip with the frame.

[0050] Furthermore, the actuator is a drive motor.

[0051] Example 2

[0052] The delay mechanism is further limited on the basis of Example 1, and the performance of Example 2 after the limitation is even better.

[0053] The delay mechanism includes a delay arm 214, which is arranged on the base through a second pin shaft and can rotate around the second pin shaft. The delay arm 214 is meshed with the fan gear on the frame, and the frame interacts with the delay arm. An arc-shaped slide groove is provided on the delay arm, and a slider is provided in the arc-shaped slide groove. The slider can slide along the arc-shaped slide groove, and the slider is connected to a pull wire or a pull rod; the pull wire or the pull rod is used to connect with the door lock body. During the electric drive stage through the actuator 213, the door lock cannot be in a semi-unlocked state or a pre-tensioned state, otherwise the door lock will fail to function. The delay arm can avoid this situation and protect the door lock; when the actuator drives the frame to flip to the pre-opening position through the cam, the frame flips, driving the delay arm to flip, and the slider slides relative to the delay arm in the arc-shaped slide groove. At this time, the pull wire or the pull rod will not move with the flipping of the frame, so that the pull wire or the pull rod will not act on the door lock at this time.

[0054] Further, an open / close switch assembly 206 is provided on the frame of the base assembly, and the open / close switch assembly 206 is provided on one side of the handle assembly;

[0055] A button cap 302 is provided on the outer surface of the handle assembly, and the handle assembly can be flipped between an upwardly flipped open position and a closed position;

[0056] When the handle assembly is located at the closed position, the handle assembly covers the base assembly and the push-on / lock switch assembly 206 thereon, and the button cap 302 contacts the contact of the push-on / lock switch assembly 206 .

[0057] Furthermore, a locking block is provided on one side of the frame, and the locking block 209 is sleeved on the second pin shaft. The locking block is hinged to the base through the second pin shaft and can rotate around the hinge point of the second pin shaft. A return spring is provided between the locking block and the base; the locking block is used specifically for when the car is in extreme situations, such as collision, skidding, etc., when the acceleration is very large, the locking block flips over and presses against the frame due to inertial acceleration, and the locking block protects the locking handle, so that the handle will not flip up and unlock due to inertia, ensuring that the door will not open by itself under extreme circumstances.

[0058] Furthermore, a limit switch 210 is provided on one side of the cam. When the cam drives the frame and the handle assembly to flip up to the pre-door opening position, the limit structure on the cam touches the limit switch 210 and the actuator stops working.

[0059] Furthermore, a lock core 208 is provided on the base assembly, and a key hole of the lock core 208 is exposed outside the base assembly. When the handle assembly is in the closed position, the key hole is covered, and when the handle assembly is in the flip-up open position, the key hole is exposed.

[0060] Furthermore, the handle assembly includes a handle bracket 303 and a handle cover 301. The handle cover 301 is arranged on the outer surface of the handle bracket, and the handle bracket 303 is connected to the frame; the handle bracket 303 is L-shaped.

[0061] Furthermore, a positioning structure 902 and / or a U-shaped spring buckle 903 are provided on the handle bracket 303 , and the positioning structure and / or the U-shaped spring buckle are obliquely inserted into corresponding grooves on the frame 202 at a certain angle.

[0062] Furthermore, an anti-deformation structure 901 is provided on the handle bracket 303. The anti-deformation structure 901 is similar to a reinforcing rib. The handle is normally flipped up at the beginning. This structure prevents the handle from being opened abnormally and buckled down from the upper edge of the handle to prevent it from falling off and deforming.

[0063] Furthermore, U-shaped grooves 801 are provided on both sides of the base assembly, and the base assembly is installed on the handle hole of the door outer panel from the back side of the door outer panel, and is hung on the edge of the handle hole of the door outer panel through the U-shaped grooves 801 on both sides.

[0064] Furthermore, a socket surface groove is provided on the outer panel of the vehicle door, and the socket surface groove is arranged below the handle assembly to form an extending space.

[0065] The working principle of this utility model:

[0066] When the handle structure is at rest, Figure 7-8 As shown, after receiving the instruction, the actuator 213 drives the cam 212 through the spline, and after the outer pull handle assembly is turned up to a certain angle, the limit structure on the cam touches the limit switch 210, and the actuator stops working. Figures 9-10 As shown, this structural feature reduces the loss of force during the transmission process, and the frame 202 and the delay arm 214 are linked by gears; Figures 13-15 As shown, the delayed rotating arm rotates from a stationary state to a certain position, and the wire is in a stationary state during the pulling process; when the handle structure is electrically flipped up, as shown in Figures 9-10 As shown, the handle assembly of the handle structure can be further flipped up to the maximum angle, such as Figures 11-12 As shown, during this process, the pull line starts to move, such as Figures 13-15 , to achieve the purpose of unlocking; when the car reaches a certain acceleration outward in a special collision environment, a locking block 209 is provided to move with the handle first, and after rotating to a certain angle, the movement of the handle can be restricted to ensure that the door will not be opened when the handle collides; the product structure realizes the characteristics of one axis for multiple uses, simple structure and high transmission efficiency.

[0067] Installation highlights: Base components, such as Figure 3 As shown, it is installed from the back of the outer plate, hung on the edge of the outer plate through the U-shaped grooves 801 on both sides, fastened by screws at both ends, and then fastened to the reinforcing plate from the upper side of the back base through bolts 207. This structure facilitates the loading process and reduces the difficulty of stamping the reinforcing plate.

[0068] like Figure 6 As shown, the handle bracket 303 in the handle assembly is provided with an anti-deformation structure 901, and the U-shaped spring buckle 903, the positioning structure 902 and the anti-deformation structure 901 are obliquely assembled with the frame 202 at a certain angle, thereby improving the structural strength of the product.
