Description

Technical Field

[0001] The invention belongs to the technical field of automobile handles, and in particular relates to a rotary hidden door handle. Background Art

[0002] As people's expectations and aesthetic tastes for cars rise, traditional handle designs in automobiles have created a gap between the door sheet metal and the handle to facilitate gripping. These handles often protrude from the door sheet metal, making them susceptible to scratches and bumps, increasing drag and noise during driving. To address these issues, hidden handles have emerged on the market. These conform to the sheet metal's curved surface while the vehicle is in motion, reducing drag and wind noise. By conforming to the sheet metal's curved surface, they effectively enhance the overall streamlined and aesthetically pleasing design. After parking, the handle can be extended to facilitate door opening.

[0003] When the hidden handle needs to be held, the internal driving structure must first be used to push one or both ends of the hidden handle out of the groove. At this time, the door lock is in a locked state. After the handle is pushed out, the passenger holds the handle and turns it outward, pulling the door lock cable to open the door lock. However, the existing hidden handle will also pull the door lock cable for a certain distance when the driving structure pushes the hidden handle out of the groove. During use, if the driving structure has an inaccurate driving stroke problem, it is very easy to open the door lock prematurely during the process of pushing the handle out, causing certain safety hazards to the passengers.

[0004] Therefore, there is an urgent need for a rotary hidden door handle to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotary hidden door handle, which is used to ensure that the door lock will not be opened when the handle is pushed out, thereby avoiding safety hazards to passengers.

[0012] A driving assembly is provided on the base, and the driving assembly can drive the handle to rotate around the shaft portion from the hidden state to the extended state. When the gripping portion of the handle is rotated from the extended state toward the unlocked state by an external force, the shaft portion can be driven to rotate around the central axis of the shaft portion, so that the abutting portion pushes the swing arm to move, thereby pulling the door lock cable.

[0013] Preferably, an end of the handle away from the gripping portion is provided with a push structure spaced apart from the shaft portion, and the driving assembly can rotate around the shaft portion by abutting against the push structure.

[0016] Preferably, the rotary hidden door handle further includes two micro switches, which are spaced apart from each other and are both arranged on the base. The two micro switches are used to detect the movement stroke of the output end of the drive assembly.

[0017] Preferably, the rotary hidden door handle further comprises an inertia lock, which is rotatably arranged on the base. The inertia lock can rotate in a direction opposite to the rotation direction of the swing arm under the action of inertia to stop the swing arm.

[0018] Preferably, a second stop structure is provided on the base, and when the inertia lock is in an initial state, the second stop structure abuts against the inertia lock.

[0019] Preferably, a first connecting hole is provided on the end of the handle away from the gripping portion, a fourth stop structure and a fifth stop structure are provided in the first connecting hole, a first limiting portion is provided on the shaft portion, and the shaft portion is rotated to pass through the first connecting hole, and when the handle rotates around the shaft portion until the fourth stop structure stops at the first limiting portion, the handle is in the hidden state, and when the handle rotates around the shaft portion until the fifth stop structure stops at the first limiting portion, the handle is in the extended state.

[0020] Preferably, second connecting holes facing each other are provided on two opposite side walls of the handle hidden groove, and a sixth stop structure and a seventh stop structure are provided in at least one of the second connecting holes. A second limiting portion is provided on the shaft body, and the shaft body is rotated to pass through the two second connecting holes.

[0022] Beneficial effects of the present invention:

[0023] The present invention provides a rotary hidden door handle, which is in a hidden state when the vehicle door is closed, that is, the handle is completely accommodated in the handle hidden groove; when the vehicle door needs to be opened, the driving component is started, and the driving component drives the handle to rotate outward from the hidden state to a first set angle around the shaft body, that is, the handle is rotated to an extended state. During this process, the handle rotates relative to the shaft body, and the shaft body is in a stationary state relative to the base. Therefore, the abutting portion fixedly connected to the shaft body is stationary relative to the base and will not move the pushing swing arm, that is, the vehicle door lock cable is not pulled; after the handle is rotated to the extended state, the passenger holds the holding portion and rotates it outward, driving the shaft body to rotate around the central axis of the shaft body, so that the abutting portion pushes the swing arm to move, thereby pulling the vehicle door lock cable, thereby realizing the opening of the vehicle door lock. Since the door lock wire is not pulled during the process of pushing the handle out of the handle hidden groove, the door lock will not be opened prematurely due to insufficient accuracy of the driving stroke of the driving component. Therefore, the rotary hidden door handle proposed in the present invention can ensure that the door lock will not be opened during the process of pushing the handle out, thereby avoiding safety hazards to passengers.

[0052] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0053] like Figures 1 to 5 As shown, this embodiment provides a rotary hidden door handle, which includes a base 1, an axle pin 2, a handle 3, a swing arm 4 and a drive assembly 5. The base 1 is provided with a handle hidden groove 11; the axle pin 2 includes a shaft body portion 21 and an abutment portion 22 fixedly connected to the shaft body portion 21, and the shaft body portion 21 is rotatably connected to the base 1 around its central axis; one end of the handle 3 is rotatably connected to the shaft body portion 21, and the other end is a gripping portion 31. The handle 3 has a hidden state in which it is completely accommodated in the handle hidden groove 11, and it rotates outward from the hidden state to a first set angle around the central axis of the shaft body portion 21. The handle 3 is in the extended state when the vehicle is in the extended state and in the unlocked state when the vehicle is rotated outward from the extended state to the second set angle around the central axis of the shaft body 21; one end of the swing arm 4 is movably connected to the base 1, and the other end is connected to the car door lock cable 6; the driving component 5 is arranged on the base 1, and the driving component 5 can drive the handle 3 to rotate around the shaft body 21 from the hidden state to the extended state. When the gripping part 31 of the handle 3 is rotated from the extended state to the unlocked state by an external force, the shaft body 21 can be driven to rotate around the central axis of the shaft body 21, so that the abutting part 22 pushes the swing arm 4 to move, so as to pull the car door lock cable 6.

[0054] The present embodiment provides a rotary hidden door handle. When the car door is closed, the handle 3 is in a hidden state, that is, the handle 3 is completely accommodated in the handle hidden groove 11; when the car door needs to be opened, the driving assembly 5 is started, and the driving assembly 5 drives the handle 3 to rotate outward from the hidden state to a first set angle around the shaft body portion 21, that is, the handle 3 rotates to the extended state. During this process, the handle 3 rotates relative to the shaft body portion 21, and the shaft body portion 21 is in a stationary state relative to the base 1. Therefore, the abutting portion 22 fixedly connected to the shaft body portion 21 is stationary relative to the base 1 and will not move the push-pushing swing arm 4, that is, the car door lock cable 6 is not pulled; after the handle 3 is rotated to the extended state, the passenger grips the gripping portion 31 and rotates it outward, driving the shaft body portion 21 to rotate around the central axis of the shaft body portion 21, so that the abutting portion 22 pushes the swing arm 4 to move, thereby pulling the car door lock cable 6, thereby realizing the opening of the car door lock. Since the door lock wire 6 is not pulled during the process of pushing the handle 3 out of the handle hidden groove 11, the door lock will not be opened prematurely due to insufficient accuracy of the driving stroke of the driving component 5. Therefore, the rotary hidden door handle proposed in this embodiment can ensure that the door lock will not be opened during the process of pushing the handle 3 out, thereby avoiding safety hazards to passengers.

[0055] In this embodiment, the shaft portion 21 and the abutting portion 22 are integrally formed.

[0056] Specifically, in this embodiment, the first setting angle is 23° and the second setting angle is 15°, that is, when in the extended state, the angle between the handle 3 and the base 1 is 23°, and when in the unlocked state, the angle between the handle 3 and the base 1 is 38°.

[0057] Specifically, if Figures 3 to 5 As shown, the end of the handle 3 away from the grip portion 31 is provided with a push structure 32 spaced apart from the shaft portion 21, and the driving assembly 5 can abut against the push structure 32 and rotate around the shaft portion 21. The driving assembly 5 abuts against and pushes the push structure 32, so that the push structure 32 drives the entire handle 3 to rotate around the shaft portion 21, thereby realizing the rotation of the handle 3 from the hidden state to the extended state.

[0058] More specifically, the drive assembly 5 includes a driver 51 and a push rod 52. The driver 51 is disposed on the base 1. One end of the push rod 52 is connected to the output end of the driver 51, and the other end is provided with an abutment head 521 capable of abutting the abutment structure 32. The driver 51 is used to drive the push rod 52 to move back and forth along the extension direction of the push rod 52 to abut or move away from the abutment structure 32. When the driver 51 drives the push rod 52 to abut the abutment structure 32, the abutment structure 32 rotates forward around the shaft portion 21 to achieve rotation of the handle 3 from the hidden state to the extended state. When the driver 51 drives the push rod 52 to abut the abutment structure 32, the abutment structure 32 can rotate in the opposite direction around the shaft portion 21 to achieve rotation of the handle 3 from the extended state to the hidden state.

[0059] Specifically, if Figures 6 to 8 As shown, a first stop structure 522 is provided on one side of the push rod 52 at the abutting joint 521. When the handle 3 is rotated to the extended state, the first stop structure 522 stops at the abutting structure 32. Figure 6 , the handle 3 is in a hidden state, the abutment head 521 abuts against the abutment structure 32, and when the driver 51 drives the push rod 52 to move in the positive direction along its axial direction, the abutment structure 32 is pushed to move. Due to the restriction of the shaft body 21, the handle 3 as a whole rotates around the shaft body 21 in the clockwise direction, thereby rotating out of the handle hidden groove 11; Figure 7 , the push structure 32 rotates to abut against the first stop structure 522, and the push structure 32 is restricted by the first stop structure 522. At this time, the handle 3 is in the extended state; the passenger holds the grip portion 31 and continues to rotate clockwise, and the push structure 32 disengages from the first stop structure 522, thereby rotating to Figure 8 Unlocked state shown.

[0060] More specifically, the abutment head 521 has a first curved abutment surface, and the push-pushing structure 32 has a second curved abutment surface, the first curved abutment surface being able to slide against the second curved abutment surface. Since the push-pushing structure 32 slides relative to the abutment head 521 when the handle 3 is rotated, the arrangement of the first and second curved abutment surfaces ensures smooth relative sliding between the two.

[0061] Specifically, the rotary hidden door handle further includes a travel detection member for detecting the movement stroke of the output end of the drive assembly 5. The travel detection member is used to achieve precise control of the handle 3 from the hidden state to the extended state by detecting the movement stroke of the output end of the drive assembly 5.

[0062] Optionally, the stroke detection element includes a Hall effect sensor, which is disposed in the drive assembly 5. The Hall effect sensor can identify the drive stroke of the driver 51 through a Hall effect rotation signal. Specifically, the Hall effect sensor can be placed on the output shaft of the driver 51 and measure the output shaft's rotation by detecting changes in the magnetic field. When the output shaft rotates, the Hall effect sensor generates a Hall effect rotation signal, the frequency of which is proportional to the rotation speed of the driver 51. By counting the Hall effect rotation signal, the number of rotations and stroke of the driver 51 can be determined.

[0063] Alternatively, as Figure 5 As shown, the travel detection member includes two micro switches 61, which are spaced apart from each other and are both provided on the base 1. When the handle 3 is in the hidden state, one micro switch 61 abuts against the push rod 52. When the driver 51 drives the push rod 52 to move and abut against the other micro switch 61, the push rod 52 moves into position, at which point the micro switch 61 controls the driver 51 to stop.

[0064] Specifically, if Figure 4 As shown, the rotary concealed door handle further includes a rotary damper 8, the output shaft of which is provided with a damping gear 81. A rack 35 extending along an arc is provided at the end of the handle 3 away from the grip portion 31, with the damping gear 81 meshing with the rack 35. The rotary damper 8 is used to control the rotational speed of the handle 3, ensuring that the speed at which the handle 3 returns from the unlocked state to the extended state is appropriate, thereby avoiding noise caused by collisions due to excessive speed.

[0065] Specifically, the rotary hidden door handle further includes an inertia lock 7, which is rotatably arranged on the base 1. The inertia lock 7 can rotate in a direction opposite to the direction of rotation of the swing arm 4 under the action of inertia to stop the swing arm 4. Figure 9 Taking the shown position as an example, when the vehicle is hit or undergoes an emergency speed change, the gripping portion 31 of the handle 3 will rotate counterclockwise under the action of inertia, thereby driving the abutting portion 22 to push the swing arm 4 to rotate counterclockwise. At this time, the inertia lock 7 rotates clockwise under the action of inertia, so that the two are close to each other until they abut each other, thereby limiting the rotation range of the swing arm 4 and preventing the door lock from being opened due to the swing arm 4 rotating too far and pulling the door lock cable 6. Therefore, the rotation range of the swing arm 4 is limited by the inertia lock 7 to prevent the door lock from being opened.

[0066] Specifically, a second stop structure 12 is provided on the base 1. When the inertia lock 7 is in the initial state, the second stop structure 12 abuts against the inertia lock 7. Figure 9 The second stop structure 12 abuts against the inertia lock 7 to limit the initial position of the inertia lock 7. Figure 10When subjected to inertia, the inertia lock 7 will disengage from the second stop structure 12 until it rotates to abut against the swing arm 4, thereby limiting the rotation of the swing arm 4 and preventing the swing arm 4 from rotating excessively and opening the door lock.

[0067] Specifically, a fourth resetting elastic member 92 is provided between the base 1 and the inertia lock 7. Under the action of the fourth resetting elastic member 92, the inertia lock 7 abuts against the second stop structure 12. When subjected to inertia, the inertia lock 7 continues to compress the fourth resetting elastic member 92. After the inertia disappears, the inertia lock 7 returns to its initial state of abutting against the second stop structure 12 under the action of the resetting elastic force of the fourth resetting elastic member 92.

[0068] Specifically, if Figure 5 、 Figure 11 and Figure 12 As shown, a first connection hole 33 is defined at the end of the handle 3 away from the grip portion 31. A fourth stop structure 341 and a fifth stop structure 342 are disposed within the first connection hole 33. A first stop portion 211 is disposed on the shaft portion 21. The shaft portion 21 rotates through the first connection hole 33. When the handle 3 rotates around the shaft portion 21 until the fourth stop structure 341 stops at the first stop portion 211, the handle 3 is in a concealed state. When the handle 3 rotates around the shaft portion 21 until the fifth stop structure 342 stops at the first stop portion 211, the handle 3 is in an extended state. The shaft portion 21 passes through the first connection hole 33, thereby achieving a rotational connection between the handle 3 and the shaft portion 21. The cooperation between the fourth stop structure 341, the fifth stop structure 342 and the first limit portion 211 limits the rotation range of the handle 3 relative to the shaft portion 21. After being rotated to the right position (the handle 3 is rotated to the extended state), the handle 3 cannot continue to rotate around the shaft portion 21. When the passenger rotates the handle 3 and continues to rotate, the shaft portion 21 can be driven to rotate synchronously, thereby realizing the push of the abutment portion 22 on the swing arm 4.

[0069] Optionally, in other embodiments, the first limiting portion 211 is a groove structure, and the inner wall of the first connecting hole 33 is provided with a protrusion structure, and the opposite side walls of the protrusion structure are respectively the fourth stop structure 341 and the fifth stop structure 342, and the protrusion structure is provided in the groove structure.

[0070] Specifically, in this embodiment, a first groove 34 is defined on the inner wall of the first connecting hole 33. Two circumferentially opposing sidewalls of the first groove 34 are formed as a fourth stop structure 341 and a fifth stop structure 342. The first limiting portion 211 is a protruding structure that radially protrudes outward from the outer wall of the shaft portion 21 and is movably disposed within the first groove 34. This arrangement limits the rotational range of the handle 3 relative to the shaft portion 21.

[0071] More specifically, in this embodiment, two opposite first grooves 34 are provided on the inner wall of the first connecting hole 33 , and correspondingly, two oppositely disposed first limiting portions 211 are provided on the shaft body 21 , further improving the reliability of the rotation range limitation.

[0072] Specifically, a first resetting elastic member is disposed between the handle 3 and the shaft portion 21. When the first resetting elastic member is in its initial position, the fourth stop structure 341 stops against the first limiting portion 211. The first resetting elastic member is used to limit the initial position of the first limiting portion 211 within the first groove 34 and to automatically reset the handle 3 after any other force acting on it is removed.

[0073] like Figures 12 to 14 As shown, two opposing side walls of the handle hidden groove 11 are provided with second connecting holes 111 facing each other, and at least one of the second connecting holes 111 is provided with a sixth stop structure 1121 and a seventh stop structure 1122. The shaft body 21 is provided with a second limiting portion 212. The shaft body 21 is rotatably inserted through the two second connecting holes 111. When the shaft body 21 rotates relative to the handle hidden groove 11 until the sixth stop structure 1121 stops at the second limiting portion 212, the handle 3 is in a hidden state or an extended state. When the shaft body 21 rotates relative to the handle hidden groove 11 until the seventh stop structure 1122 stops at the second limiting portion 212, the handle 3 is in an unlocked state. The shaft body 21 is rotatably inserted through the two second connecting holes 111, thereby achieving a rotational connection between the shaft body 21 and the base 1. The cooperation between the sixth stop structure 1121, the seventh stop structure 1122 and the second limiting portion 212 limits the rotation angle of the shaft portion 21 relative to the base 1, and limits the position of the handle 3 in the extended state and the unlocked state.

[0074] Optionally, in other embodiments, the first limiting portion 211 is a groove structure, and the inner wall of the first connecting hole 33 is provided with a protrusion structure, and the opposite side walls of the protrusion structure are respectively the sixth stop structure 1121 and the seventh stop structure 1122, and the protrusion structure is provided in the groove structure.

[0075] Specifically, in this embodiment, a second groove 112 is defined on the inner wall of the second connection hole 111. Two opposing sidewalls of the second groove 112 along the circumference of the second connection hole 111 are respectively a sixth stop structure 1121 and a seventh stop structure 1122. The second limiting portion 212 is a protruding structure that protrudes radially outward from the outer wall of the shaft body 21 and is movably disposed within the second groove 112. This configuration limits the rotational range of the shaft body 21 relative to the base 1.

[0076] Specifically, a second resilient member is disposed between the base 1 and the shaft portion 21. In the initial position of the second resilient member, the sixth stop structure 1121 abuts against the second position-limiting portion 212. The second resilient member is configured to limit the initial position of the second position-limiting portion 212. Furthermore, after any external force acting on the shaft portion 21 is removed, the second resilient member automatically resets the shaft portion 21.

[0077] Specifically, if Figure 12 As shown, the swing arm 4 is rotatably connected to the base 1. An arcuate groove 41 is provided at a position of the swing arm 4 that is offset from its rotational center axis. An abutment ball head 221 is provided at a position of the abutment portion 22 that is away from the shaft body 21. The abutment ball head 221 can slide against the arcuate groove 41 to rotate against the swing arm 4. The mutual cooperation between the abutment ball head 221 and the arcuate groove 41 enables the abutment portion 22 to smoothly push the swing arm 4.

[0078] More specifically, if Figure 5 As shown, a third resetting elastic member 91 is provided between the swing arm 4 and the base 1. After the abutting portion 22 is separated from the swing arm 4, the third resetting elastic member 91 drives the swing arm 4 to automatically reset.

[0079] Specifically, if Figure 13 As shown, a driver mounting groove 13, a push rod sliding groove 14 and a damper mounting groove 15 are provided on one side of the groove of the base 1 away from the handle hidden groove 11. The driver 51 is installed in the driver mounting groove 13, the push rod 52 is slidably set in the push rod sliding groove 14, and the damper 8 is installed in the damper mounting groove 15.
