[0021] Beneficial effects:

[0022] This invention provides a concealed door handle that automatically pops out when power is off, including a mounting base, a door handle frame, a driving power component, a driving linkage, and an opening rod. The driving power component is fixedly installed in the mounting base. One end of the driving linkage is pivotally connected to the bottom of the door handle frame, and the other end is pivotally connected to the telescopic rod of the driving power component.

The user can then pull the door handle frame to unlock the door. When the door is icy, the combined force of the drive unit, the first torsion spring, and the second torsion spring can provide greater ice-breaking force, making it easier to pop out the handle. In addition, if an accident causes the motor to lose power, the drive unit will no longer constrain the drive linkage. At this time, the door handle frame will automatically pop out under the action of the first and second torsion springs to ensure rescue and allow rescuers to easily unlock the door.

[0024] This invention provides a vehicle including a concealed door handle that automatically pops out when power is off. This vehicle offers the advantages described above compared to existing technologies, which will not be elaborated further here. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0044] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0045] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a concealed door handle that automatically pops out when power is off, including a mounting base 100, a door handle frame 200, a driving power component 300, a driving linkage 400, and an opening rod 500. The driving power component 300 is fixedly installed in the mounting base 100. One end of the driving linkage 400 is pivotally connected to the bottom of the door handle frame 200, and the other end is pivotally connected to the telescopic rod of the driving power component 300. A first torsion spring 410 is provided between the driving linkage 400 and the telescopic rod, which enables the driving linkage 400 to have a tendency to pop out the door handle frame 200. A second torsion spring 420 is provided between the driving linkage 400 and the door handle frame 200, which also enables the door handle frame 200 to have a tendency to pop out.

[0046] Specifically, when the car needs to pop out the door handle to unlock, the drive power component 300, the first torsion spring 410, and the second torsion spring 420 work together to push out the door handle frame 200. Then, the user can pull the door handle frame 200 to unlock the car door. When the car door is iced, the combined force of the drive power component 300, the first torsion spring 410, and the second torsion spring 420 can provide greater ice-breaking force, making it easier to pop out the door. In addition, after an accident causes the motor to lose power, the drive power component 300 loses power and no longer restrains the drive linkage 400. At this time, the door handle frame 200 automatically pops out under the action of the first torsion spring 410 and the second torsion spring 420 to ensure rescue and make it easy for rescuers to unlock the car door.

[0047] Among them, the driving power component 300 can be a linear motor. After the driving power component 300 is de-energized, the driving power component 300 will not restrict the movement of the door opening lever 500.

[0048] See Figure 1 - Figure 7 As shown, in an optional embodiment, the side wall of the mounting base 100 is provided with a first guide groove 110, and the two sides of the drive linkage 400 are provided with first guide rods 430 that can be adapted to the first guide groove 110; one end of the door opening rod 500 is pivotally connected to the bottom of the door handle frame 200, and the other end of the door opening rod 500 is provided with a second guide rod 510; the side wall of the mounting base 100 is provided with a second guide groove 120 that is adapted to the second guide rod 510; the length of the second guide groove 120 is longer than the length of the first guide groove 110.

[0049] See Figure 1 - Figure 7 As shown, in the optional solution of this embodiment, the hidden door handle that can automatically pop out when the power is off also includes a door opening pull lock 600. The door opening pull lock 600 is fixedly installed on the outside of the mounting base 100. The door opening pull lock 600 is located on one side of the second guide slide groove 120 so that the second guide slide rod 510 can trigger the door opening pull lock 600.

[0050] See Figure 1 - Figure 7 As shown, in the optional embodiment, the drive linkage 400 includes a first linkage 401 and a second linkage 402, which are integral structures; the first linkage 401 is pivotally connected to the telescopic rod of the drive power component 300, and the second linkage 402 is pivotally connected to the door handle frame.

[0051] See Figure 1 - Figure 7As shown, in the optional scheme of this embodiment, a rotation limit block 403 is provided at the connection between the first link 401 and the second link 402, and a rotation limit stop 210 adapted to the rotation limit block 403 is provided at the bottom of the door handle frame 200.

[0052] The connection angle between the first link 401 and the second link 402 is an obtuse angle.

[0053] Among them, the door handle 500 is arc-shaped.

[0054] See Figure 1 - Figure 7 As shown, in the optional solution of this embodiment, the door handle frame 200 is provided with a push-limiting protrusion 220, and the mounting base 100 is provided with a limiting baffle 130 for matching the push-limiting protrusion 220.

[0055] See Figure 1 - Figure 7 As shown, in an optional embodiment, a third torsion spring 440 is provided between the drive link 400 and the door handle frame 200, and the third torsion spring 440 can make the door handle frame 200 have a tendency to return to its original position.

[0056] The second torsion spring 420 and the third torsion spring 440 can be set separately or a double torsion spring structure can be adopted. Those skilled in the art can choose according to actual needs.

[0057] See Figure 5 As shown, specifically, when the door handle is in its initial position, i.e., when the door handle frame 200 has not popped out, the drive power component 300 is in a standby state. The drive power component 300 can limit the drive linkage 400, so that the drive linkage 400 is fixed and will not be driven to move by the first torsion spring 410 and the second torsion spring 420. At this time, the first torsion spring 410 and the second torsion spring 420 are in the maximum torque state, and the first torsion spring 410 and the second torsion spring 420 can make the door handle frame 200 have a tendency to pop out. That is, when the drive power component 300 is de-energized or starts working, the door handle frame 200 can pop out. At this time, the first guide slide 430 of the drive linkage 400 is located at the starting position of the first wire slide groove on the mounting base 100, and the second guide slide 510 of the door opening lever 500 is located at the starting position of the second wire slide groove on the mounting base 100.

[0058] See Figure 6As shown, when the door handle pops out, the user can pull the door handle to unlock the door. At this time, the drive power component 300 moves to its farthest point, that is, the telescopic rod on the drive power component 300 moves to its farthest point, thereby driving the drive linkage 400 to move. One end of the drive linkage 400, which is pivotally connected to the drive power component 300, translates, while the other end of the drive linkage 400 is lifted upward in cooperation with the first guide slide rod 430 and the first guide slide groove 110. At the same time, the rotating part on the drive linkage 400... The movable limit block 403 can abut against the rotation limit stop 210 on the door handle frame 200. At this time, the drive linkage 400 can push against the door handle frame 200, and the first torsion spring 410 and the second torsion spring 420 are fully released with zero elastic torque. In addition, the first guide slide 430 of the drive linkage 400 is located at the end of the first wire guide groove on the mounting base 100, and the second guide slide 510 of the door opening lever 500 is located in the middle of the second wire guide groove on the mounting base 100. During the pop-out process of the door handle frame 200, the flat push limit protrusion 220 on the door handle frame 200 matches the limit stop 130 of the mounting base 100 to ensure that the door handle frame 200 pops out straight. In case of emergency, when the vehicle power is cut off, the drive power component 300 is instantly de-energized and unlocked, and the first torsion spring 410 and the second torsion spring 420, which are in the maximum torque state, are immediately released, and the door handle frame 200 pops out.

[0059] See Figure 7 As shown, when the user pulls the handle to unlock the door, the drive unit 300 moves to its farthest point, meaning the telescopic rod on the drive unit 300 moves to its farthest point. When the user pulls the door handle frame 200, the end of the door handle frame 200 connected to the door opening lever 500 rotates relative to the end of the door handle frame 200 connected to the drive linkage 400. At this time, the first torsion spring 410 and the second torsion spring 420 do not move, the third torsion spring 440 is compressed, and the second guide slide rod 510 of the door opening lever 500 continues to slide within the second guide groove 120. When the second guide slide rod 510 slides to the end of the second guide groove 120, the portion of the second guide slide rod 510 protruding from the second guide groove 120 triggers the door unlocking latch 600. This means the portion of the second guide slide rod 510 protruding from the second guide groove 120 drives the door unlocking latch 600 to rotate, thus tightening the latch of the door unlocking latch 600 and unlocking the door. After the user releases the door handle frame 200, the third torsion spring 440 and the torsion spring inside the door unlocking latch 600 will cause the door handle frame 200 to return to its flat position. To completely retract and hide the door handle frame 200, the drive power component 300 needs to operate to drive the drive linkage 400 to return to its original position. During this process, the first torsion spring 410 and the second torsion spring 420 are compressed to their maximum state.

[0060] This embodiment provides a car that includes a hidden door handle that automatically pops out when power is off.

[0061] Specifically, the car provided in this embodiment has the advantage of a hidden door handle that can automatically pop out when the power is off, compared with the prior art, which will not be repeated here.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
