Description

Technical Field

[0001] The invention relates to a vehicle door handle, in particular to a hidden vehicle door handle with a sliding block. Background Art

[0002] The hidden handle is flush with the door panel, and the surface of the door panel is flat and beautiful. It can not only prevent the handle from being hit due to protruding from the door panel surface, ensuring its long service life, but also reduce the wind resistance of the vehicle when used in the vehicle field. The existing hidden handle has many transmission structure parts and high assembly requirements. Summary of the invention

[0003] In order to solve the problem of many transmission parts in the hidden handle in the prior art, the present invention provides a hidden door handle with a slider and has a compact structure.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A hidden door handle with a slider, comprising a reinforcing plate for mounting the door handle, a swing arm swinging in a direction parallel to the door panel being rotatably connected to the inner side of the reinforcing plate, a handle being rotatably arranged on the reinforcing plate, the swing arm being connected to an elastic reset structure, the handle being in a hidden state as a first position, and the handle being in a turned-out state as a second position, an actuator being arranged on the reinforcing plate, the actuator comprising a screw rod extending or retracting, the screw rod head being rotatably connected to a slider, the handle root being located between the slider and the swing arm, a first micro switch, a second micro switch and a position switch for unlocking by touching the swing arm being arranged on the reinforcing plate;

[0006] When the handle head in the first position is pressed, the handle touches the first micro switch, the first micro switch gives a signal, and the actuator pushes the handle to rotate to the second position through the slider;

[0007] When the handle head in the second position is pressed, the handle root drives the slider to rotate so that the slider touches the second micro switch, the second micro switch gives a signal, the actuator retracts the screw, and the elastic reset structure drives the handle to return to the first position through the swing arm.

[0008] Furthermore, the rotation center line of the slider is perpendicular to the axial direction of the screw rod, and a matching structure is provided between the handle root and the slider, and when the handle root moves, the slider is driven to rotate through the matching structure.

[0009] As an embodiment of the present invention, the matching structure includes a top hook arranged on the base of the handle, and the slider has an action surface matching with the top hook, and the thrust direction of the top hook on the action surface does not pass through the rotation centerline of the slider.

[0010] Furthermore, the action surface is a plane.

[0011] Furthermore, the slider is provided with a rounded chamfer on the edge of the action surface, and the top hook at the root of the handle is provided with an arc groove that matches the rounded corner. The slider is provided with a rounded chamfer on the edge of the action surface, and the top hook at the root of the handle is provided with an arc groove that matches the rounded corner. In this way, when the slider pushes the handle backward, the transition is smooth and there is no jamming.

[0012] As another embodiment of the present invention, the matching structure includes a first wedge block arranged at the root of the handle, and the slider has a second wedge block. The first wedge block is wedged with the second wedge block, and when the first wedge block moves, the second wedge block is lifted so that the slider rotates.

[0013] Furthermore, the first wedge block is provided with a strip groove along the movement direction of the slider, and the second wedge block is provided with a convex rib matching the strip groove, and the strip groove is inserted into the convex rib.

[0014] Furthermore, the reinforcing plate is also provided with a limit structure for limiting the position of the slider, and the limit structure is a slideway provided on the reinforcing plate, and the slider is placed in the slideway. Through the limit of the slideway, the slider can be swung within a certain range, and the handle root can be pushed back at the same time. The reinforcing plate is also provided with a limit block for limiting the position of the slider near the second micro switch. The limit block can limit the rotation limit position of the slider to prevent the slider from applying too much pressure on the second micro switch when the handle is forcibly pressed, resulting in overpressure or even damage to the second micro switch.

[0015] Furthermore, a balance block is provided at the rotation center of the handle, an inertia lock is also rotatably provided on the reinforcement plate, and a torsion spring is provided between the inertia lock and the reinforcement plate. The balance block on the handle can prevent the handle from rotating when the car collides. When the car collides, the inertia lock and the swing arm start to move at the same time under the action of inertia force. Because the acceleration of the inertia lock is greater than the acceleration generated by the swing arm, the inertia lock rotates out first to block the rotating swing arm, so that the swing arm stops moving, effectively preventing the door from unlocking after the car is hit, and improving safety.

[0016] Furthermore, the position switch is a three-state switch, having contacts and springs. When the handle is in the first position, the springs do not press the contacts. When the handle is in the second position, the swing arm drives the springs to press the contacts to a first compressed state. The position switch in the first compressed state does not send a signal. When the handle is in the unlocking position, the swing arm drives the springs to press the contacts to a second compressed state. The position switch in the second compressed state sends an unlocking signal.

[0017] Beneficial effects:

[0018] (1) The slider of the present invention is rotatably arranged at the head of the screw rod, and the slider can push the base of the handle forward, and the base of the handle can also push the slider backward through a matching structure, which has a compact structure, fewer parts, and saves costs;

[0019] (2) The door handle of the present invention does not require space to be reserved for buttons, and has a beautiful appearance. In addition, the door handle of the present invention realizes a manual locking function, which can be done by simply pressing the head of the handle, and is easy and quick to operate;

[0020] (3) A top hook is provided at the base of the handle, and an action surface cooperating with the top hook is provided on the slider. The thrust direction of the top hook on the action surface does not pass through the rotation center line of the slider. Thus, when the handle is rotated, the top hook presses against the slider to realize the rotation of the slider;

[0021] (4) The limit block on the reinforcing plate of the present invention can limit the rotation limit position of the slider, thereby preventing the slider from exerting too much pressure on the second micro switch when the handle is forcibly pressed, causing the second micro switch to be over-pressurized or even damaged, thereby extending the service life of the parts;

[0022] (5) The balance weight and inertia lock in the present invention can ensure that the handle is not opened during a door safety collision, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] like Figures 1 to 7 A hidden door handle with a slider comprises a reinforcing plate 1 for mounting a door handle 2, a swing arm 3 swinging in a direction parallel to the door panel being rotatably connected to the inner side of the reinforcing plate 1, a handle 2 being rotatably provided on the reinforcing plate 1, the swing arm 3 being connected to an elastic reset structure, the reset structure being a torsion spring or the like, the handle 2 being in a hidden state as a first position, the handle 2 being in a turned-out state as a second position, an actuator 3 being provided on the reinforcing plate 1, the actuator 3 comprising an extended or retracted screw rod 41, the head of the screw rod 41 being rotatably connected to a slider 5, the handle root 21 being located between the slider 5 and the swing arm 3, a first micro switch 6, a second micro switch 7 and a position switch 8 for the swing arm 3 to touch to realize unlocking being provided on the reinforcing plate 1; the first micro switch 6, the second micro switch 7 and the position switch 8 are all provided with spring sheets in front thereof, when the corresponding spring sheets are pressed down and touch the first micro switch 6, the second micro switch 7 or the position switch 8, the corresponding switches respond.

[0041] When the handle head 22 in the first position is pressed, the handle 2 touches the first micro switch 6, the first micro switch 6 gives a signal, and the actuator 3 pushes the handle 2 to rotate to the second position through the slider 5;

[0042] When the handle head 22 in the second position is pressed, the handle base 21 drives the slider 5 to rotate so that the slider 5 touches the second micro switch 7. The second micro switch 7 gives a signal, the actuator 3 retracts the screw 41, and the elastic reset structure drives the handle 2 to return to the first position through the swing arm 3.

[0043] There is a matching structure between the handle base 21 and the slider 5 , and when the handle base 21 moves, the slider 5 is driven to rotate through the matching structure.

[0044] The rotation centerline of the slider 5 is perpendicular to the axial direction of the screw rod 41. The reinforcing plate 1 is also provided with a limiting structure for limiting the slider 5. The limiting structure is a slideway provided on the reinforcing plate 1, and the slider 5 is placed in the slideway. In this way, the slider 5 will not rotate too much, and at the same time, the stability of the slider 5 when pushing the handle base 21 back is ensured. Fig.14 The reinforcing plate 1 also has a limit block 11 for limiting the position of the slider near the second micro switch 7. The limit block 11 can limit the rotation limit position of the slider 5 to prevent the slider 5 from applying too much pressure on the second micro switch 7 when the handle is forcibly pressed, resulting in overpressure or even damage to the second micro switch 7.

[0045] like Fig.15 A balance block 23 is provided at the rotation center of the handle 2, and an inertia lock 9 is also rotatably provided on the reinforcement plate 1, and a torsion spring is provided between the inertia lock 9 and the reinforcement plate 1. The torsion spring enables the inertia lock 9 to avoid the swing arm 3 when in working state. The balance block 23 on the handle 2 can prevent the handle 2 from rotating when the car collides. When the car is hit, the inertia lock 9 and the swing arm 3 start to move at the same time under the action of inertia force. Because the acceleration of the inertia lock 9 is greater than the acceleration generated by the swing arm 3, the inertia lock 9 rotates out first, blocks the rotating swing arm 3, and stops the swing arm 3 from moving, effectively preventing the door from unlocking after the car is hit, thereby improving safety.

[0046] The position switch 8 is a three-state switch. The position switch 8 has contacts and springs. When the handle is in the first position, the springs do not press the contacts; when the handle is in the second position, the swing arm 3 drives the springs to press the contacts to the first compression state, and the position switch 8 in the first compression state does not send a signal; when the handle is in the unlocking position, the swing arm 3 drives the springs to press the contacts to the second compression state, and the position switch 8 in the second compression state sends an unlocking signal.

[0047] The matching structure includes the following embodiments:

[0048] Embodiment 1:

[0049] like Figures 8 to 10The matching structure includes a top hook 211 disposed on the handle root 21, and the slider 5 has an action surface 51 that matches the top hook 211. The thrust direction of the top hook 211 on the action surface 51 does not pass through the rotation center line of the slider 5. The action surface 51 is a plane. The top hook structure is adopted, and the action force is concentrated and the response is fast. In actual operation, the action point of the top hook can be slightly farther from the rotation center line of the slider, so that the pushing process is more labor-saving.

[0050] The slider 5 is provided with a round chamfer 511 at the edge of the action surface 51 , and the top hook 211 of the handle root 21 is provided with an arc groove 212 matching the round chamfer.

[0051] Embodiment 2:

[0052] like Figures 11 to 13 The matching structure includes a first wedge block 213 disposed at the handle root 21, and a second wedge block 52 is provided on the slider 5. The first wedge block 213 is engaged with the second wedge block 52. When the first wedge block 213 moves, the second wedge block 52 is lifted up, so that the slider 5 rotates. The transmission process is smooth by adopting the wedge block form.

[0053] Embodiment 3:

[0054] like Figures 11 to 13 The main structure is the same as that of the second embodiment, the first wedge block 213 is provided with a strip groove 214, the strip groove 214 is along the movement direction of the slider 5, the second wedge block 52 is provided with a convex rib 53 matching the strip groove 214, and the strip groove 214 is inserted into the convex rib 53. The strip groove 214 cooperates with the convex rib 53 to play a guiding and limiting role, and the transmission process is more stable.

[0055] Working process:

[0056] The handle 2 is initially in the first position. When the handle head 22 is pressed, the handle root 21 touches the first micro switch 6, and the first micro switch 6 gives a signal. The actuator 3 pushes the handle 2 to rotate to the second position through the slider 5. At this time, the handle 2 is in the rotated-out position. At this time, a person's hand can reach under the handle 2 to pull the handle 2. After the handle 2 is pulled to a certain extent, it reaches the unlocking position, and the swing arm 3 rotates and touches the position switch 8 to unlock; after the person releases the handle 2, the elastic reset structure drives the swing arm 3 to rotate, and the swing arm 3 pushes the handle 2 back to the second position. At this time, the handle head 22 is pressed, and the handle root 21 drives the slider 5 to rotate so that the slider 5 touches the second micro switch 7. The second micro switch 7 gives a signal, and the actuator 3 retracts the screw 41, and the elastic reset structure drives the handle 2 to return to the first position through the swing arm 3.

[0057] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
