A hidden door handle 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 8, the hidden door handle 1 includes a base 100, a first transmission mechanism 200, a second transmission mechanism 300, a handle 400, a driving mechanism 500, a first return torsion spring 600, and a second return torsion spring 700.

One end of the first transmission mechanism 200 is rotatably mounted on the base 100, one end of the second transmission mechanism 300 is rotatably mounted on the base 100, the handle 400 has a first end 401 and a second end 402 along its length direction, the first end 401 is rotatably connected with the other end of the first transmission mechanism 200, the second end 402 is rotatably connected with the other end of the second transmission mechanism 300, and the handle 400 is movable between a hidden position, an ejected position and an unlocked position. The handle 400 does not extend beyond the exterior surface of the door when in the stowed position, and extends beyond the exterior surface of the door when in the ejected position, and the handle 400 is pulled outward from the door through the second end 402 when in the ejected position to move to the unlocked position.

The driving mechanism 500 is mounted to the base 100, and the driving mechanism 500 drives the handle 400 from the hidden position to the ejected position through the first transmission mechanism 200 and the second transmission mechanism 300. The first reset torsion spring 600 is provided at the junction of the first transmission mechanism 200 and the base 100 and resets the handle 400 from the ejected position to the hidden position through the first transmission mechanism 200, and the second reset torsion spring 700 is provided at the junction of the second transmission mechanism 300 and the base 100 and resets the handle 400 from the unlocked position to the ejected position and resets the handle 400 from the ejected position to the hidden position through the second transmission mechanism 300.

For example, the handle 400 may include a handle body 410 and a handle cover 420, where the handle body 410 and the handle cover 420 are limited by ribs or the like, and are fixed by threaded fasteners (e.g., bolts and screws). And, when the door is rotatably connected with the vehicle body with its front end, the first end 401 is located on the front side of the second end 402; when the vehicle door is rotatably connected with the vehicle body by the rear end thereof, the first end 401 is positioned at the rear side of the second end 402, which is more suitable for the stressing habit of the human body.

According to the hidden door handle 1 of the embodiment of the present invention, by moving the handle 400 between the hidden position, the ejected position, and the unlocked position, and the handle 400 is located at the hidden position so as not to exceed the outer surface of the door, the handle 400 is located at the ejected position so as to protrude from the outer surface of the door, and the handle 400 is located at the ejected position so as to be pulled out of the door through the second end 402 to move to the unlocked position.

Thus, when a user does not control the key to send a signal to the vehicle, the handle 400 does not exceed the outer surface of the vehicle door, the wind resistance is small when the vehicle runs, the vehicle is not easy to scratch with objects outside the vehicle, and the handle 400 is not easy to scratch when the vehicle stops; when the user controls the key to send a signal to the vehicle, the handle 400 is beyond the outer surface of the vehicle door and can be pulled by the user, so that the opening of the vehicle door is realized, the condition that the vehicle door is directly opened due to the fact that the vehicle door receives the signal can be avoided, the safety is high, and meanwhile, the user can conveniently open the vehicle door.

In addition, one end of the first transmission mechanism 200 is rotatably installed to the base 100, one end of the second transmission mechanism 300 is rotatably installed to the base 100, the handle 400 has a first end 401 and a second end 402 along its length direction, the first end 401 is rotatably connected to the other end of the first transmission mechanism 200, the second end 402 is rotatably connected to the other end of the second transmission mechanism 300, the driving mechanism 500 is installed to the base 100, and the driving mechanism 500 drives the handle 400 from the hiding position to the ejecting position through the first transmission mechanism 200 and the second transmission mechanism 300.

Because the first transmission mechanism 200 and the second transmission mechanism 300 are both rotatably connected with the handle 400, compared with the door handle outside the vehicle, which is formed by matching a sliding groove with a sliding block between a rotating arm and the handle in the related art, the hidden door handle 1 of the embodiment of the invention is convenient to manufacture and assemble, has low production cost, and the connection structures at the two ends of the handle 400 are not easy to deform, so that noise generated in the process of switching the unlocking position of the handle 400 from the ejecting position can be avoided. In addition, one driving mechanism 500 can drive the first transmission mechanism 200 and the second transmission mechanism 300 to move, so that the number of parts is reduced, the size is smaller, and the cost is lower.

In addition, the first reset torsion spring 600 is disposed at the connection between the first transmission mechanism 200 and the base 100, and resets the handle 400 from the pop-up position to the hidden position through the first transmission mechanism 200, and by disposing the first reset torsion spring 600 at the connection between the first transmission mechanism 200 and the base 100, a reset structure (such as a torsion spring) is not required between the first transmission mechanism 200 and the handle 400, which is beneficial to realizing the blocking effect when the handle 400 is located at the pop-up position and the unlocked position, and the required installation space of the hidden door handle 1 is small. Further, the first return torsion spring 600 drives the first transmission mechanism 200 to have a longer arm of force, and is smoother in the process of returning the driving handle 400 from the ejecting position to the hiding position.

And, the second reset torsion spring 700 locates the junction of second drive mechanism 300 and base 100 and through second drive mechanism 300 with handle 400 from the unblock position reset to pop-up position and with handle 400 from pop-up position reset to hiding the position, second reset torsion spring 700 can realize that handle 400 resets to pop-up position from the unblock position, and then from pop-up position reset to hiding the position like this, simple to operate and part quantity are few, occupation space is little.

Thus, the hidden door handle 1 according to the embodiment of the present invention has advantages of smooth resetting, low noise, small volume, low cost, and the like.

According to some embodiments of the present invention, as shown in fig. 3, 5 and 8, the first transmission mechanism 200 includes a base pin 210 and a rotating arm 220.

The base pin 210 is disposed on the base 100, one end of the rotating arm 220 is rotatably connected to the base pin 210, and the other end of the rotating arm 220 is rotatably connected to the first end 401 of the handle 400. The first reset torsion spring 600 is sleeved on the base pin 210, and two ends of the first reset torsion spring are respectively connected with the base 100 and the rotating arm 220.

In this way, the driving mechanism 500 can drive the rotating arm 220 to rotate around the base pin 210, the relative position between the driving mechanism 500 and the base pin 210 is fixed, and the rotating arm 220 can drive the first end 401 of the handle 400 to extend out of the outer surface of the vehicle door when rotating, so that the first end 401 of the handle 400 moves to a position where the first end 401 of the handle 400 is located when the handle 400 is located at the ejecting position. At this time, the first reset torsion spring 600 is twisted to have an elastic reset force, and when the driving mechanism 500 stops driving the rotating arm 220, the elastic reset force of the first reset torsion spring 600 acts on the rotating arm 220 to drive the rotating arm 220 to rotate reversely around the base pin 210, so as to drive the first end 401 of the handle 400 to be gradually hidden into the outer surface of the vehicle door until the first end 401 of the handle 400 moves to a position where the first end 401 of the handle 400 is located when the handle 400 is located at the hidden position.

Thus, on the one hand, the rotation axis of the first reset torsion spring 600 is the same as that of the rotation axis of the rotation arm 220, and is the central axis of the base pin shaft 210, and the base pin shaft 210 can fix the first reset torsion spring 600 and the rotation arm 220 at the same time, so that the installation structure is simplified, and on the other hand, a reset structure (such as a torsion spring) is not required between the rotation arm 220 and the handle 400, which is beneficial to realizing the blocking effect when the handle 400 is located at the pop-up position and the unlock position, and the required installation space of the hidden door handle 1 is small.

In addition, compared with the door handle outside the vehicle, which is formed by matching a sliding groove with a sliding block between the rotating arm and the handle in the related art, the rotating arm 220 and the handle 400 in the embodiment of the invention are in rotary connection, so that the processing, the manufacturing and the assembly are convenient, the production cost is low, the connection structure between the rotating arm 220 and the handle 400 is not easy to deform, and noise generated between the rotating arm 220 and the handle 400 when the handle 400 is switched between the three positions can be avoided.

Further, as shown in fig. 8, the first end 401 of the handle 400 is provided with a damper gear 430, and the other end of the rotation arm 220 is provided with gear teeth 221 engaged with the damper gear 430. Thus, when the user pulls the handle 400 from the pop-up position to the unlock position, the damping gear 430 and the gear teeth 221 of the rotating arm 220 are engaged to generate damping force, so that the situation that the user moves too fast to generate severe impact due to excessive force is avoided, the generation of impact noise is avoided, the damage probability of the handle 400 can be reduced, the movement of the handle 400 is more stable, and the service life of the handle 400 is prolonged.

Alternatively, as shown in fig. 3, 5 and 8, the rotating arm 220 is configured with a recess 222 recessed toward the direction of the driving mechanism 500. In this way, on the one hand, the length dimension of the rotation arm 220 can be reduced, and on the other hand, the driving mechanism 500 can be brought into contact with the recess 222 so that the other end of the rotation arm 220 pushes the handle 400 to move from the hiding position to the ejecting position, and the moving direction of the rotation arm 220 and the driving direction of the driving mechanism 500 are not parallel, i.e., by providing the recess 222, the moving direction of the rotation arm 220 can be controlled, whereby the dimensions of both the rotation arm 220 and the driving mechanism 500 in the driving direction of the driving mechanism 500 can be reduced, facilitating the arrangement of the rotation arm 220 and the driving mechanism 500.

According to some embodiments of the present invention, as shown in fig. 3, 5 and 8, the second transmission mechanism 300 includes a rotation shaft 310, a connection arm 320 and a link 330.

The rotating shaft 310 is rotatably disposed on the base 100, one end of the connecting arm 320 is connected to the rotating shaft 310, and the connecting arm 320 rotates along with the rotating shaft 310, one end of the connecting rod 330 is rotatably connected to the other end of the connecting arm 320, and the other end of the connecting rod 330 is rotatably connected to the second end 402 of the handle 400. The second reset torsion spring 700 is sleeved on the rotating shaft 310, and two ends of the second reset torsion spring are respectively connected with the base 100 and the rotating shaft 310.

For example, the other end of the connecting rod 330 and the second end 402 of the handle 400 are engaged by a connectable shaft, i.e. the connecting shaft is inserted into the other end of the connecting rod 330 and the second end 402 of the handle 400 respectively, the connecting shaft is in interference fit with the connecting rod 330, and the connecting shaft is in interference fit with the handle 400.

In this way, the driving mechanism 500 can drive the connecting arm 320 to rotate around the rotation shaft 310, the relative position between the driving mechanism 500 and the rotation shaft 310 is fixed, the connecting arm 320 can drive the connecting rod 330 to move when rotating, and the connecting rod 330 pushes the second end 402 of the handle 400 to extend out of the outer surface of the vehicle door, so that the second end 402 of the handle 400 moves to a position where the second end 402 of the handle 400 is located when the handle 400 is located in the ejecting position. At this time, the second restoring torsion spring 700 is twisted to have an elastic restoring force, and when the driving mechanism 500 stops driving the connection arm 320, the elastic restoring force of the second restoring torsion spring 700 acts on the connection arm 320 to drive the connection arm 320 to reversely rotate around the rotation shaft 310, and the connection arm 320 drives the link 330 to move, so that the link 330 drives the second end 402 of the handle 400 to be gradually hidden into the outer surface of the vehicle door until the second end 402 of the handle 400 moves to a position where the second end 402 of the handle 400 is located when the handle 400 is located at the hidden position.

And, when the handle 400 is in the pop-up position, the user pulls the handle 400, the first end 401 of the handle 400 is hardly moved, and the second end 402 of the handle 400 is gradually moved in a direction away from the outer surface of the door until the handle 400 is moved to the unlock position, so that the door can be pulled open. At this time, the second end 402 of the handle 400 drives the link 330 to move, the link 330 drives the connecting arm 320 to rotate around the rotation axis 310, the second return torsion spring 700 is continuously twisted, and when the user cancels pulling the handle 400, the elastic return force of the second return torsion spring 700 acts on the link 320 to drive the link 320 to rotate reversely around the rotation axis 310, the link 320 drives the link 330 to move, so that the link 330 drives the second end 402 of the handle 400 to return to the ejecting position.

In this way, on the one hand, the rotation axis of the second return torsion spring 700 is the same as the rotation axis of the connecting arm 320, and is the central axis of the rotation shaft 310, and the rotation shaft 310 can fix the second return torsion spring 700 and the connecting arm 320 at the same time, simplifying the installation structure, wherein the rotation shaft 310 and the connecting arm 320 can be formed into a whole, on the other hand, the connecting rod 330 and the handle 400 do not need to be provided with a return structure (such as torsion spring, etc.), which is beneficial to realizing the blocking effect when the handle 400 is located at the ejecting position and the unlocking position, and the required installation space of the hidden door handle 1 is small.

In addition, compared with the door handle outside the vehicle, which is formed by matching a sliding groove with a sliding block between the connecting rod and the handle in the related art, the connecting rod 330 and the handle 400 in the embodiment of the invention are in rotary connection, so that the processing, the manufacturing and the assembly are convenient, the production cost is low, the connecting structure between the connecting rod 330 and the handle 400 is not easy to deform, and noise generated between the connecting rod 330 and the handle 400 when the handle 400 is switched from the ejecting state to the unlocking state can be avoided.

In addition, the second transmission mechanism 300 has two rotation points, namely, one rotation point exists between the rotation shaft 310 and the connecting arm 320, and one rotation point exists between the connecting arm 320 and the connecting rod 330, so that the second transmission mechanism 300 has higher freedom of deformation and displacement, and the second transmission mechanism 300 is beneficial to the switching process of the three positions of the handle 400.

Further, the base 100 is provided with a stopper rib for defining a rotatable angle of the rotation shaft 310. By limiting the rotatable angle of the rotation shaft 310, the maximum limit angle between the second end 402 of the handle 400 and the outer surface of the door can be limited, so that excessive rotation of the handle 400 after switching to the unlocking position can be avoided, thereby reducing the overall damage probability of the hidden door handle 1.

Alternatively, as shown in fig. 3 and 8, the driving mechanism 500 is located at one side of the connection arm 320 in the length direction of the base 100, and the link 330 extends toward the other side of the connection arm 320 in the length direction of the base 100. In this way, no matter where the handle 400 is located, the driving mechanism 500 can only contact with the connecting arm 320, that is, the connecting arm 320 can separate the connecting arm 320 and the connecting rod 330, so that the driving mechanism 500 can avoid interfering with the movement of the connecting rod 330, which is beneficial to reliable switching of the state of the handle 400.

In some alternative embodiments of the present invention, as shown in fig. 2 and 4, the hidden door handle 1 further includes a third reset torsion spring 800 and a zipper wire 312.

The rotating shaft 310 is provided with a zipper block 311 which rotates along with the rotating shaft, the third reset torsion spring 800 is sleeved on the rotating shaft 310, two ends of the third reset torsion spring are respectively connected with the base 100 and the zipper block 311, one end of the zipper wire 312 is connected with the zipper block 311, and the other end of the zipper wire is suitable for being connected with a door lock of a vehicle. Wherein the third reset torsion spring 800 resets the handle 400 from the unlocked position to the ejected position and the zipper wire 312 through the second transmission mechanism 300.

Thus, when the handle 400 is located at the unlocking position, the second end 402 of the handle 400 can drive the connecting rod 330 to displace, the connecting rod 330 drives the connecting arm 320 to rotate, the connecting arm 320 drives the rotating shaft 310 to rotate, and at this time, the locking piece 311 rotates synchronously with the rotating shaft 310, so that the locking wire 312 is pulled by the locking piece 311, i.e. the door lock is pulled to unlock the vehicle door. At this time, the third reset torsion spring 800 is pushed by the zipper block 311 to be twisted, and the third reset torsion spring 800 has an elastic reset force, so when the user cancels pulling the handle 400, the second reset torsion spring 700 and the third reset torsion spring 800 can jointly drive the handle 400 to move towards the pop-up position, the reset force of the handle 400 from the unlocking position to the pop-up position is more sufficient, the door lock can be ensured to be locked again, and the locking of the door is more reliable.

Wherein the second return torsion spring 700 is located inside the base 100 and the third return torsion spring 800 is located outside the base 100. Thus, the base 100 can separate the second reset torsion spring 700 from the third reset torsion spring 800, so that interference between the second reset torsion spring 700 and the third reset torsion spring 800 is avoided, and reset smoothness of the handle 400 is ensured.

According to some embodiments of the present invention, as shown in fig. 3 and 8, the drive mechanism 500 includes an actuator 510 and a push rod 520.

The actuator 510 is mounted to the base 100, and the push rod 520 is connected to the actuator 510 and is driven to extend and retract by the actuator 510. Wherein the push rod 520 pushes the first transmission mechanism 200 and the second transmission mechanism 300 when being driven to extend by the actuator 510 to drive the handle 400 from the hidden position to the ejected position; the push rod 520, when driven to retract by the actuator 510, allows the first and

second transmission mechanisms

200 and 300 to return the handle 400 from the ejected position to the hidden position under the influence of the first and second return torsion springs 600 and 700, respectively.

For example, an elastic sleeve may be disposed between the actuator 510 and the base 100, and the elastic sleeve is disposed on an outer surface of the actuator 510 and is in interference fit with the actuator 510, and the elastic sleeve may be made of a silica gel material or a rubber material. Also, an end of the actuator 510 facing the push rod 520 may be inserted into the push rod 520 to ensure a reliable connection between the actuator 510 and the push rod 520. In addition, the actuator 510 may include a motor and gear structure in driving connection with a battery.

By arranging the actuator 510, a driving force for displacement can be provided for the first transmission mechanism 200 and the second transmission mechanism 300, so that the first transmission mechanism 200 and the second transmission mechanism 300 can drive the handle 400 to switch from a hidden state to an ejecting state, and by arranging the push rod 520, when the push rod 520 moves, the first transmission mechanism 200 and the second transmission mechanism 300 are simultaneously caused to move, the structure is simpler, and the occupied installation space is small.

Further, as shown in fig. 3 and 4, when the handle 400 is located at the ejecting position, the first transmission mechanism 200 is stopped against the push rod 520 to cooperate with the first reset torsion spring 600 to maintain the position of the first end 401 of the handle 400, specifically, the rotating arm 220 is stopped against the push rod 520 to cooperate with the first reset torsion spring 600 to maintain the position of the first end 401 of the handle 400, that is, the rotating arm 220 is simultaneously pushed by the push rod 520 in opposite directions to be under the elastic force of the first reset torsion spring 600, and the base pin 210 is fixed with the base 100, and one end of the rotating arm 220 is fixed by the base pin 210, so that the rotating arm 220 is limited by three forces in different directions when the handle 400 is located at the ejecting position, and the position of the rotating arm 220 is fixed under the condition that the three forces are unchanged and the rotating arm 220 is not subjected to new forces, so that the position stability of the first end 401 of the handle 400 can be ensured.

And, when the handle 400 is positioned at the ejecting position, the second transmission mechanism 300 is stopped against the push rod 520 to cooperate with the second return torsion spring 700 to maintain the position of the second end 402 of the handle 400, specifically, the connecting arm 320 is stopped against the push rod 520 to cooperate with the second return torsion spring 700 to maintain the position of the second end 402 of the handle 400, that is, the connecting arm 320 is simultaneously pushed by the push rod 520 in opposite directions to be under the elastic force of the second return torsion spring 700, and the rotating shaft 310 is fixed with the base 100, one end of the connecting arm 320 is fixed by the rotating shaft 310, so that the connecting arm 320 is limited by three different directional forces when the handle 400 is positioned at the ejecting position, and the position of the connecting arm 320 is fixed under the condition that the three forces are unchanged and the connecting arm 320 is not subjected to new forces, so that the position stability of the second end 402 of the handle 400 can be ensured.

Optionally, the base 100 is provided with a recess, and the push rod 520 slidably fits into the recess. In this way, the walls of the grooves can provide a guiding effect on the movement of the push rod 520 to improve the reliability of the movement of the push rod 520, thereby making the movement of the handle 400 between the hidden position and the ejected position more stable.

For example, the engaging block 230 is mounted on a side of the rotating arm 220 facing the push rod 520, the bottom wall of the first engaging groove 521 may be set to be irregularly shaped according to a specific structure, and when the push rod 520 moves, the bottom wall of the first engaging groove 521 may drive the rotating arm 220 to rotate around the base pin 210 through the engaging block 230, so that the rotating arm 220 can be ensured to drive the handle 400 to switch the pop-up position from the hidden position.

And, one end of the push rod 520 adjacent to the second transmission mechanism 300 is provided with a second engagement groove 522, and when the push rod 520 is driven to extend by the actuator 510, the second engagement groove 522 pushes the second transmission mechanism 300 through the bottom wall thereof.

For example, the second matching groove 522 and the first matching groove 521 are spaced apart, that is, the second matching groove 522 is not communicated with the first matching groove 521, and the connecting arm 320 is inserted into the second matching groove 522, so that the side wall of the second matching groove 522 can limit the connecting arm 320, so that the relative position between the connecting arm 320 and the push rod 520 is fixed, and the relative displacement between the connecting arm 320 and the push rod 520 is prevented.

According to some embodiments of the present invention, as shown in fig. 8, the base 100 includes a first housing 110 and a second housing 120.
