Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and particularly to an in - turning door handle, a door and a vehicle. Background Art

[0002] At present, after the hidden external handle on the market is opened, the handle operation part protrudes out of the vehicle outer panel ( Figure 1 ). When the handle operation part protrudes out of the vehicle outer panel, the occupant pulls the operation part to open the door. Since the handle operation part of such a hidden handle protrudes out of the vehicle outer panel, the handle part is easily bumped and damaged, and the maintenance cost is high. Moreover, the overall Y - direction dimension of the external handle assembly is large (about 65 mm), the layout space requirement is large, and the layout is difficult. Therefore, it is necessary to develop an in - turning handle to improve the above problems. Summary of the Invention

[0003] In view of the above - mentioned disadvantages of the prior art, the present invention provides an in - turning door handle, a door and a vehicle to improve the problem that the handle part is bumped and damaged due to the handle operation part protruding out of the vehicle outer panel.

The handle is mounted in the handle mounting groove and rotatably connected to the handle base. The linear driving device is disposed on the handle base. The link mechanism is rotatably mounted on the handle base. The driving input end of the link mechanism is hinged to the linear driving device, and the action output end of the link mechanism is slidably connected to the handle. Wherein, when the linear driving device is activated, it drives the link mechanism to drive the handle blocking the handle mounting groove to rotate towards the inner side of the handle base, so as to expose the handle mounting groove.

[0005] In an example of the present invention, the linear driving device includes an electric actuator and a push rod. The push rod is connected to the output end of the electric actuator, and the electric actuator drives the push rod to perform a linear reciprocating motion.

[0006] In an example of the present invention, a first accommodation cavity and a slideway are provided on the handle base. The electric actuator is mounted in the first accommodation cavity, and the slideway is disposed on one side of the output end of the electric actuator. The push rod performs a linear reciprocating motion along the slideway.

[0007] In an example of the present invention, the connecting rod structure includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are fixedly connected to form a V-shaped swing arm. The intersection of the first connecting rod and the second connecting rod is rotatably installed on the handle base. One end of the first connecting rod away from the intersection is slidably connected to the handle, and one end of the second connecting rod away from the intersection is hinged to the push rod.

[0008] In an example of the present invention, at the intersection of the first connecting rod and the second connecting rod, there are a first bushing and a second bushing protruding toward the handle base side. The first bushing is arranged on the periphery of the second bushing. A third bushing is correspondingly provided on the handle base. The third bushing is inserted into the second bushing and fixed by a first rotating shaft.

[0009] In an example of the present invention, a first torsion spring is provided at the connection between the connecting rod mechanism and the handle base. The first torsion spring is sleeved on the second bushing, and both ends of the first torsion spring are respectively fixed on the first bushing and the handle base.

[0010] In an example of the present invention, a slot is provided at the position where the first connecting rod is connected to the handle. A first connecting seat is provided on the handle and is matched with the slot. The handle and the first connecting rod are slidably connected through the cooperation of the first connecting seat and the slot.

[0011] In an example of the present invention, a handle mounting seat is provided below the handle mounting groove corresponding to the handle base. Second connecting seats are respectively provided at both ends of the handle. The handle mounting seat and the second connecting seat are rotatably connected by a second rotating shaft.

[0012] In an example of the present invention, a second torsion spring is provided on the second rotating shaft. The second torsion spring is sleeved on the second rotating shaft, and two torsion output ends of the second torsion spring are respectively connected to the second connecting seat.

[0013] In an example of the present invention, the inwards-opening vehicle door handle further includes an unlocking switch. The unlocking switch is arranged above the handle mounting groove and is electrically connected to the control module.

[0014] In an example of the present invention, a sealing device is provided between the handle and the handle mounting groove. The sealing device is arranged circumferentially along the outer edge of the handle mounting groove.

[0015] In an example of the present invention, the inwards-opening vehicle door handle further includes a handle rear cover. The handle rear cover is installed on the handle base.

[0016] On the other hand, the present invention provides a vehicle door. The vehicle door includes an outer vehicle door panel and the inwards-opening vehicle door handle of the present invention. The inwards-opening vehicle door handle is installed on the outer vehicle door panel.

[0017] The present invention also provides a vehicle, which includes the door of the present invention or the inwards-folding door handle of the present invention.

[0018] For the inwards-folding door handle of the present invention, a link mechanism is used to convert the linear motion of a linear driving device into a rotational motion, thereby driving the handle to fold inwards towards the inside of the door to achieve the inwards-folding contraction of the handle, solving the problem that the handle is prone to being bumped and damaged when popping outwards, and at the same time compressing the overall Y-direction layout space of the handle, optimizing the structure of the door handle and reducing costs.

[0019] The link mechanism in the present invention adopts an arm structure similar to a V shape, which can not only be rotatably connected to the handle base, but also be hinged to the handle and the linear driving device. The linear motion of the push rod of the linear driving device drives the arm to rotate around the rotating shaft. Since the arm is connected to the handle, the rotation of the arm drives the handle to rotate towards the inside of the handle mounting groove, thereby realizing the transmission of the force of the linear driving device; torsion springs are provided at the joints of the link mechanism and the handle with the handle base, which can make the link mechanism and the handle always maintain a resilience force and have a tendency to return to the initial position.

[0039] Please refer to Figures 1 to 14 , the present invention provides an inverting door handle, a door and a vehicle to improve the problem that the handle is easily bumped and damaged when it pops out of the vehicle.

[0040] Please refer to Figure 1 and Figure 2 , the inverting door handle of the present invention includes a handle base 100, a handle 200, a link mechanism 300 and a linear driving device 400. Among them, a handle mounting groove 110 is provided on the handle base 100, and the handle 200 is mounted in the handle mounting groove 110 and rotatably connected to the handle base 100; the linear driving device 400 is arranged on the handle base 100 and is used to drive the handle 200 to rotate; the link mechanism 300 is rotatably mounted on the handle base 100, and the driving input end of the link mechanism 300 is hinged to the linear movement driving end of the linear driving device 400, and the action output end of the link mechanism 300 is slidably connected to the handle 200. When the door is closed, the handle 200 covers the handle mounting groove 110 and is flush with the outer panel of the vehicle door; when the linear driving device 400 is started, the linear driving device 400 drives the handle 200 covering the handle mounting groove 110 to rotate inwardly towards the handle base 100 to expose the handle mounting groove.

[0041] Please refer to Figure 2 and Figure 3, in one embodiment, the linear drive device 400 includes an electric actuator 410 and a push rod 420. The push rod 420 is installed at the output end of the electric actuator 410. The output power of the electric actuator 410 is a linear driving force, and the push rod 420 makes a linear reciprocating motion under the drive of the electric actuator 410. In this embodiment, the handle base 100 is a box-shaped cavity formed by a bottom plate and side plates located around the bottom plate. One side of the box-shaped cavity is provided with a first accommodation cavity 120 for installing the electric actuator and a slideway 130 for the push rod 420 to slide. The other side is provided with a second accommodation cavity 140 for installing the link mechanism 300 and the handle 200. The electric actuator 410 is installed in the first accommodation cavity 120 through fasteners. The slideway 130 is arranged at the output end of the electric actuator 410. The slideway 130 is arranged along the transverse direction of the handle base 100. The push rod 420 makes a linear reciprocating motion in the slideway 130 under the action of the electric actuator 410. The link mechanism 300 is installed at a position in the second accommodation cavity 140 corresponding to the slideway 130. The linear motion of the push rod 420 can drive the link mechanism 300 to rotate, and then drive the handle 200 to flip inward towards the handle base 100. The electric actuator 410 in this embodiment can adopt a conventional actuator assembly in the art, and its specific structure will not be elaborated here. In other embodiments, other existing linear drive devices can be adopted, such as a drive motor and a worm and worm gear transmission assembly cooperating with the drive motor. The worm and worm gear transmission assembly can convert the rotational motion of the drive motor into a linear motion.

[0042] Please refer to Figures 5 to 7 , wherein, Figure 6The arrow directions in represent the rotation directions of the connecting rod mechanism and the handle, respectively. In one embodiment, the connecting rod mechanism 300 includes a first connecting rod 310 and a second connecting rod 320, the first connecting rod 310 and the second connecting rod 320 are fixedly connected to form a V-shaped rotating arm, and the intersection of the first connecting rod 310 and the second connecting rod 320 is rotatably mounted on the handle base 100. In other embodiments, the first connecting rod 310 and the second connecting rod 320 may also be an integrated structure. The end of the first connecting rod 310 away from the intersection of the first connecting rod 310 and the second connecting rod 320 is the action output end of the connecting rod mechanism 300, and the action output end is slidably connected to the handle 200. For example, the first connecting rod 310 is provided with a protrusion 311 on the side facing the handle 200, and a card slot 312 is provided inside the protrusion 311. The first connecting seat 210 matching the card slot 312 is provided at the corresponding position of the handle 200. The protrusion 311 can be two protrusions arranged opposite to each other, and the gap between the two protrusions forms the card slot 312; the protrusion 311 can also be an integrated structure, and the card slot 312 is provided in the middle of the protrusion. Here, there is no restriction on the formation method of the card slot 312. The first connection seat 210 protrudes from the inner surface of the handle 200. For example, the first connection seat 210 includes two spaced-apart seat bodies 211 and a crossbeam 212 connecting the two seat bodies 211. Preferably, the seat body 211 is a triangular prism structure, the crossbeam 212 is mounted on the base 211, and the two ends of the crossbeam 212 are respectively connected to the two seat bodies 211. The first connection seat 210 and the handle 200 can be an integrated structure or a split connection structure. The crossbeam 212 is always inserted into the card slot 212. The longitudinal dimension of the crossbeam 212 is smaller than the opening dimension of the card slot 312, so that the crossbeam 212 and the card slot 212 form a sliding pair. As the connecting rod mechanism 310 rotates, the first connecting rod 310 slides along the crossbeam 212, and at the same time drives the handle 200 to flip inward.

[0043] See also Figure 2 , Figure 5 and Figures 8 to 10 , Figure 10The arrow in [description] indicates the rotation direction of the handle from the closed position to the open position. One end of the second link 320, which is away from the intersection of the first link 310 and the second link 320, is the power input end of the linkage mechanism 300, and the power input end is hinged to the push rod 420. For example, one end of the push rod 420 is fixedly connected to the output end of the electric actuator 410, and a card slot is provided at the other end. The second link 320 is inserted into the card slot and is hinged to the push rod 420 through a pin shaft. The electric actuator 410 drives the push rod 420 to move linearly forward (in the direction away from the electric actuator 410), and the push rod 420 drives the linkage mechanism 300 to rotate counterclockwise. As the linkage mechanism 300 rotates, the first link 310 slides along the cross beam 212 of the first connection base 210, and at the same time presses down the handle 200 to cause the handle 200 to flip inward towards the handle base 100, and the handle 200 changes from the closed position to the open position; similarly, when the electric actuator 410 drives the push rod 420 to move linearly backward (in the direction towards the electric actuator 410), the push rod 420 drives the linkage mechanism 300 to rotate clockwise. As the linkage mechanism 300 rotates, the first link 310 slides reversely along the cross beam 212, and at the same time pushes up the handle 200, and the handle 200 returns from the open position to the closed position. The linkage structure 300 adopts a V-shaped swing arm structure, which can not only ensure the normal rotational movement of the linkage mechanism, but also transmit the linear movement of the push rod 420 to the handle 200 to cause it to flip inward towards the handle base and reset to be flush with the outer panel of the vehicle door.

[0044] Please refer to Figures 3 to 5, in one embodiment, the link mechanism 300 is rotatably connected to the handle base 100 through a first rotating shaft 350. Specifically, at the intersection of the first link 310 and the second link 320, there are a first bushing 330 and a second bushing 340 protruding towards the handle base 100. The first bushing 330 is arranged on the outer periphery of the second bushing 340 and forms an annular bushing with the second bushing 340. Corresponding to this on the handle base 100, there is a third bushing 150 protruding from the handle base 100. The outer diameter of the third bushing 150 matches the inner diameter of the second bushing 340, and the inner diameter matches the outer diameter of the first rotating shaft 350. The third bushing 150 is inserted into the second bushing 340 and realizes the rotational connection through the first rotating shaft 350. Preferably, a torsion spring is also provided at the connection between the link mechanism 300 and the handle base 100. Here, the torsion spring is denoted as the first torsion spring 360. The first torsion spring 360 is installed between the first bushing 330 and the second bushing 340, and both ends of the first torsion spring 360 are respectively connected to the handle base 100 and the link mechanism 300. For example, a first installation groove 331 is provided on the side wall of the first bushing 330, a bushing fixing seat 151 is provided on the outer periphery of the third bushing 150, and a second installation groove 152 is provided on the side wall of the bushing fixing seat 151. The first torsion spring 360 is accommodated in the space between the first bushing 330 and the second bushing 340 and is sleeved on the second bushing 340. Both ends of the first torsion spring 360 are respectively accommodated in the first installation groove 321 and the second installation groove 152. The setting of the first torsion spring 360 can enable the link mechanism to always maintain a resilience force and have a tendency to return to the initial position.

[0045] Please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9, in one embodiment, the handle mounting groove 110 is provided on the bottom plate of the handle base 100, above the link mechanism 300. The inner chamber of the handle mounting groove 110 provides a space for the flipping of the handle 200. The handle 200 is mounted in the handle mounting groove 110 and is rotatably connected to the handle base 100 through the second rotating shaft 170. Specifically, a handle mounting seat 160 is provided at the position corresponding to the lower part of the handle mounting groove 110 on the handle base 100. The handle mounting seat 160 includes an end portion and a middle portion, and through holes for the rotating shaft to pass through are provided on both the end portion and the middle portion. A second connecting seat 220 is correspondingly provided on one side of the handle 200. The second connecting seat 220 is of an arched structure. One end of the arched structure is fixed on the handle 200, and the other end is provided with a through hole for the rotating shaft to pass through. The second rotating shaft 170 passes through the through holes on the handle mounting seat 160 and the second connecting seat 220 to connect the two together. When the link mechanism 300 rotates around the first rotating shaft 350 driven by the push rod 420, it drives the handle 200 to rotate around the second rotating shaft 170, so as to realize the inward flipping of the handle 200 or the restoration of the flipping to the initial position. Preferably, a sealing structure 230 is provided between the handle 200 and the handle mounting groove 110. The sealing structure 230 can be a sealing ring arranged along the circumferential direction of the handle mounting groove 110. When the handle 200 is closed, the sealing ring can seal the gap between the handle base 100 and the handle 200.

[0046] Please refer to Figure 3 and Figure 7 , preferably, a torsion spring is provided at the connection between the handle 200 and the handle base 100. Here, the torsion spring is denoted as the second torsion spring 180. The second torsion spring 180 includes two torsion output portions 181 and a connecting portion 182 connecting the two torsion output portions 181. The two torsion output portions 181 are respectively sleeved on the second connecting seats 220 at both ends of the handle 200, and the output ends of the torsion output portions 181 are fixed on the second connecting seats 220. The connecting portion 182 bypasses from the bottom of the middle portion of the handle mounting seat 160. The setting of the second torsion spring 180 can make the handle 200 always maintain a resilience force and have a tendency to return to the initial position. In other embodiments, two torsion springs can also be selected. The two torsion springs are respectively sleeved on the second rotating shaft, and both ends of the torsion spring are respectively fixed on the second connecting seat 220 and the handle mounting seat 160.

[0047] Please refer to Figure 1 , Figure 2 , Figure 8 , Figure 10 , Figure 11, in one embodiment, an unlocking switch 190 is provided inside the handle base 100, and a handle opening button 240 is provided on the outer side of the handle 200. The unlocking switch 190 and the handle opening button 240 are respectively signal-connected to a control module such as a DCM (Data Communication Module) or a BCM (Body Control Module) to implement the function of unlocking the vehicle door by touching the handle. The unlocking switch 190 can be an unlocking capacitor or a push-button switch. The unlocking switch 190 is arranged at a position where the hand can touch after the handle 200 is opened. Preferably, the unlocking switch 190 is arranged at a position corresponding to the upper part of the handle mounting groove 110, so that after the handle 200 is opened, the unlocking switch 190 can be touched in time. The unlocking process of the vehicle door is as follows: When the user approaches the vehicle and touches the handle opening button 240 on the handle 200, after the control module DCM or BCM receives the signal, it controls the electric actuator 410 to start. The push rod 420 pushes the link mechanism 300 to rotate, and the link mechanism 300 drives the handle 200 to flip towards the inside of the vehicle door, exposing the handle mounting groove 110. The user's hand extends into the handle base 100 through the handle mounting groove 110 to touch the unlocking switch 190 inside. The unlocking switch 190 sends a door lock release signal to the control module, and the control module sends an unlocking instruction to the door lock, and the vehicle door lock is unlocked.
