Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door handles, in particular to a hidden vehicle door handle, a vehicle door and a vehicle. Background Art

[0002] Traditional car handles are exterior components that extend above the vehicle's sheet metal. Simply pulling the handle unlocks and opens the door. Recently popular, concealed door handles are often used on new energy vehicles. These handles are normally retracted into the door's sheet metal and only pop out when needed, reducing the vehicle's air resistance and enhancing its aesthetic appeal. However, these common concealed door handles suffer from a large number of parts, a complex transmission system, and low transmission efficiency. For example, patent publication number CN210217430U discloses a concealed exterior door handle structure for automobiles, specifically describing its transmission process as follows: "A push block of a motor extends, driving an actuating rod to swing and simultaneously sliding the push rod. The actuating rod extends the handle's first mounting portion, which then pushes the unlocking rod to slide along a horizontal guide section. The unlocking rod then slides along a curved guide section. The sliding movement of the unlocking rod extends the handle's second mounting portion, thereby extending the entire handle. When the handle is lifted, a second guide post rotates a locking ring, which then connects to the door's unlocking latch, thereby unlocking the door." In this transmission structure, the handle needs to cooperate with the actuating rod, the unlocking rod, and the second guide column respectively, and the unlocking rod needs to cooperate with the push rod. The complex structure will reduce the transmission efficiency. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0028] See also Figure 1-Figure 2 This embodiment discloses a hidden door handle, including a mounting bracket 2, which is embedded in the door sheet metal and has two side surfaces. The mounting bracket 2 is a mounting and supporting component for the overall structure of the door handle. The mounting bracket 2 is connected to a handle assembly 1, a driving unit, and a transmission assembly. The handle assembly 1 has at least three position states: a hidden position, a pop-up position, and an unlocked position. The driving unit acts on the handle assembly 1 to drive the handle assembly 1 to pop out from the hidden position to the pop-up position; the handle assembly 1 acts on the transmission assembly, and the transmission assembly is connected to a clamping sleeve 8 for cooperating with the unlocking structure of the door handle. The handle assembly 1 is pulled to move from the pop-up position to the unlocking position. During the movement, the handle assembly 1 pushes the transmission assembly to move, so that the clamping sleeve 8 acts on the unlocking structure of the door handle to unlock the door. The unlocking structure is a structure such as a pull rod or a pull wire.

[0029] In this embodiment, handle assembly 1 serves as the human-machine interface for unlocking the vehicle door. It is mounted within a recessed slot on one side of a mounting bracket 2. A rotational axis 3 is vertically disposed within the recessed slot within the mounting bracket 2. One end of handle assembly 1 is pivotally connected to the mounting bracket 2 via this rotational axis 3. When not in use, handle assembly 1 within the recessed slot lies flush with the door sheet metal, concealing it. When in use, the other end of handle assembly 1 rotates and pops out, allowing the door to be unlocked by pulling it.

[0030] Specific, combined Figure 3 The handle assembly 1 includes a handle body 101 and a toggle portion 102 fixedly connected to the rear end of the handle body 101. The toggle portion 102 corresponds to the position of the rotation axis 3. The toggle portion 102 passes through the mounting bracket 2 and extends out the other side of the mounting bracket 2. It cooperates with the drive unit and the transmission assembly respectively. The specific cooperation method will be described in detail below. To enhance the connection stability between the handle body 101 and the toggle portion 102, the toggle portion 102 is preferably welded to the handle body 101, but an integrally molded structure can also be used.

[0031] In a preferred embodiment, the handle assembly 1 further includes a protective portion 103, such as Figure 1As shown, the protective portion 103 is constructed as an annular structure that matches the shape of the handle body 101. The ring is arranged at the edge of the recessed groove of the mounting bracket 2. Connection methods such as bonding and crimping can be used to ensure the sealing and aesthetics of the connection. For example, the protective portion 103 can be made of materials with good sealing properties such as rubber pads and liners.

[0032] like Figure 2 As shown, the drive unit is connected to the other side of the mounting bracket 2 and includes an actuator 4 with an output shaft and a cam 5 connected to the output shaft via a spline. Rotation of the output shaft drives the cam 5. The cam 5 is close to the toggle portion 102 of the handle assembly 1. When rotated, it can abut against the toggle portion 102 and push the toggle portion 102 to move, thereby driving the handle body 101 to rotate about the rotation axis 3, switching it from a hidden position to an ejected position.

[0033] The following references Figure 3 The structure of the toggle portion 102 is described in detail. The toggle portion 102 includes a toggle base 1021 and a toggle top block 1022 fixed to the upper end surface of the toggle base 1021. The two cooperate to form an L-shaped structure. The cam 5 is positioned within the L-shaped connection space, and the thrust generated by it acts on the toggle top block 1022. The side end of the toggle base 1021 is also connected to a toggle protrusion 1023 for engaging with the transmission assembly. The toggle protrusion 1023 is located on the opposite side of the cam 5.

[0034] like Figure 2 As shown, the transmission assembly further includes a rotary block 6 and a rocker arm 7 that cooperates with the rotary block 6. The rotary block 6 is connected to the other side of the mounting bracket 2 and is arranged on the side of the actuator 4. The rotary block 6 is rotatable and has a first rotation through-hole. Through the first rotation through-hole, it rotates and cooperates with the first rotation shaft 201 fixed to the mounting bracket 2. The rocker arm 7 is also connected to the other side of the mounting bracket 2, close to the rotary block 6. The rocker arm 7 is also rotatable and has a second rotation through-hole. Through the second rotation through-hole, it rotates and cooperates with the second rotation shaft 202 fixed to the mounting bracket 2. The rotary block 6 is close to the toggle portion 102 and cooperates with the toggle protrusion 1023. When the handle body 101 is pulled from the eject position to the unlocked position, the toggle protrusion 1023 acts on the rotary block 6, pushing the rotary block 6 to rotate. The rotation of the rotary block 6 triggers the movement of the rocker arm 7, so that the clamping sleeve 8 connected to it acts on the unlocking structure of the vehicle door, thereby unlocking the vehicle door.

[0035] The following references Figure 4The exemplary structure of the swivel block 6 will be described in detail. In this exemplary structure, the swivel block 6 includes a support portion 601, with a first rotation hole disposed therein. It should be noted that the swivel block 6 should have a predetermined thickness to ensure sufficient depth for the first rotation hole to form a stable and reliable rotational engagement with the corresponding first rotation shaft 201. Extending from the support portion 601 away from the first rotation hole are formed a first engagement portion 602 for engaging with the toggle portion 102 and a second engagement portion 603 for engaging with the rocker arm 7.

[0036] The first matching portion 602 and the toggle protrusion 1023 are positioned correspondingly, and are constructed as a slope structure. When the toggle portion 102 rotates around the rotation axis 3, the toggle protrusion 1023 acts on the slope structure and pushes the rotary block 6 to rotate as a whole around the first rotation axis 201. For example, Figure 4 As shown, the slope structure of the first mating portion 602 is an easily machined slope structure. When the toggle protrusion 1023 presses against the slope of the first mating portion 602 along the tangent direction of the rotation trajectory, the pressing force can push the slewing block 6 to rotate about the first rotation axis 201. In other embodiments not shown, the slope structure can also adopt a curved surface structure, or an arc groove or ball groove structure that matches the shape of the toggle protrusion 1023.

[0037] In order to reduce the friction between the toggle protrusion 1023 and the first matching part 602 and reduce the force loss, in a preferred embodiment, the contact surface between the toggle protrusion 1023 and the first matching part 602 adopts a spherical arc structure to reduce the contact area between the two. This structure can also prevent the toggle protrusion 1023 from causing pressure loss on the slope surface of the first matching part 602 of the rotating block 6.

[0038] The positions of the second matching portion 603 and the rocker arm 7 correspond to each other. In this embodiment, the second matching portion 603 is constructed as a protruding block structure. During the rotation of the rotary block 6, the second matching portion 603 abuts against the rocker arm 7 and pushes the rocker arm 7 to rotate.

[0039] The following references Figure 5The exemplary structure of the rocker arm 7 is described in detail. In this exemplary structure, the rocker arm 7 is an integrally molded structure of a predetermined length. It includes an active portion 701 and a passive portion 702, respectively disposed at each end, and a follower plate 703 connected therebetween. A third mating portion 704 and a fourth mating portion 705 are fixedly disposed on either side of the follower plate 703. Specifically, a second rotational through-hole is provided in the active portion 701, allowing the rocker arm 7 to rotate as a whole about the second rotation axis 202. The passive portion 702, at the other end, is used to connect to the ferrule 8. The third mating portion 704 is configured to mate with the second mating portion 603 and is constructed as a corresponding baffle or plate. The fourth mating portion 705 is configured to mate with the microswitch 9 on the vehicle door. The microswitch 9 is interlocked with the vehicle's control center. When the fourth mating portion 705 presses the microswitch 9, a signal is transmitted to the vehicle's control center, indicating that the handle body 101 has reached a predetermined position, thereby issuing control commands for the vehicle's windows or other related systems.

[0040] It is understandable that the hidden door handle provided in this embodiment also includes a reset structure (not shown in the figure). After the handle assembly 1 is pulled to unlock the door, the handle body 101 is released, and the rocker arm 7, the rotary block 6, and the handle body 101 all move in the opposite direction driven by the reset structure and return to the pop-up position. At the same time, the actuator 4 is given an instruction to control the cam 5 to reverse, and the reset structure drives the handle assembly 1 back to the initial hidden position. In this embodiment, the reset structure adopts the existing technology. For example, the reset structure can include a first elastic member installed on the second rotating shaft 202, such as an elastic structure such as a torsion spring. The first elastic member is used to drive the transmission assembly to reset. The reset structure also includes a second elastic member installed on the rotating shaft 3. The second elastic member is used to drive the handle assembly 1 to reset. The reset structure belongs to the common existing technology, and its structure and principle will not be described in detail here.

[0041] It should be noted that the first elastic member can also be used to limit the position of the rotary block 6 when it is not in use. Specifically, Figure 2 As shown, the first elastic member and the rocker arm 7 can limit the counterclockwise rotation direction of the slewing block 6, while the limitation of the clockwise rotation direction of the slewing block 6 can be achieved by setting a blocking block (not shown in the figure) on the mounting bracket 2 on the corresponding side.

[0042] For ease of understanding, the following describes the operating principle of the hidden door handle provided by this embodiment with reference to the relevant drawings:

[0043] 1. The handle body 101 is in a hidden position

[0044] like Figure 1 、 Figure 2At this point, the handle body 101 is located within the recessed groove, flush with the door sheet metal, and appears to be hidden. The actuator 4 and cam 5 of the drive unit are both in their initial positions, with the cam 5 at its minimum height. The toggle portion 102 of the handle assembly 1 is not in contact with the rotary block 6, and the rotary block 6 is not in contact with the rocker arm 7.

[0045] 2. The handle body 101 switches from the hidden position to the pop-up position

[0046] like Figure 6 、 Figure 7 After the actuator 4 receives the electric deployment command, the internal motor is energized and rotates, thereby driving the cam 5 connected to it to rotate. During the rotation of the cam 5, the height changes from minimum to maximum, and acts on the toggle portion 102 of the handle assembly 1, thereby driving the handle body 101 to rotate to the pop-up position. At this time, the toggle protrusion 1023 of the handle body 101 also just contacts the first matching portion 602 of the rotary block 6.

[0047] 3. The handle body 101 switches from the pop-up position to the unlocked position

[0048] like Figure 8 、 Figure 9 When the handle body 101 is in the ejected position, the handle body 101 is manually pulled further, and the toggle protrusion 1023 is pressed against the inclined surface of the first matching portion 602 along the tangential direction of the rotation trajectory, and the rotary block 6 is pushed to rotate along the first rotation axis 201, thereby causing the second matching portion 603 of the rotary block 6 to contact the rocker arm 7;

[0049] Continue to pull the handle body 101, so that the second matching part 603 of the rotating block 6 squeezes the third matching part 704 of the rocker arm 7, pushing the rocker arm 7 to rotate along the second rotating axis 202, and then the clamping sleeve 8 connected to the driven part 702 of the rocker arm 7 pulls the unlocking structure of the car door to achieve unlocking.

[0050] 4. The handle body 101 returns to the hidden position

[0051] When the human hand does not act on the handle body 101, the various components of the door handle will return to the pop-up state under the action of the reset structure. At this time, if the actuator 4 receives a closing command, the actuator 4 will drive the cam 5 to reverse, and the height of the cam 5 will change from maximum to minimum. The handle assembly 1 will also return to the hidden state under the action of the reset structure. At this time, each component returns to its initial position.

[0052] In order to prevent the handle body 101 and the transmission assembly from resetting at too high a speed, thereby causing a safety hazard or equipment damage hazard, in a preferred embodiment, the door handle further includes a buffer assembly.

[0053] Combine Figure 2 and Figure 4Specifically, the buffer assembly includes a damper 11 connected to the other side of the mounting bracket 2. The damper 11 is used to cooperate with the transmission assembly to buffer its reset speed. Exemplarily, the damper 11 corresponds to the position of the slewing block 6. The slewing block 6 also includes a fifth mating portion 604 extending from the support portion 601 in a direction away from the first rotating through hole. The damper 11 and the fifth mating portion 604 cooperate to buffer the reset speed of the slewing block 6 and the rocker arm 7. Exemplarily, the damper 11 can be a gear damper 11. Correspondingly, the end of the fifth mating portion 604 is constructed as a meshing tooth structure that is compatible with the gear damper 11.

[0054] Preferably, the buffer assembly also includes a buffer head 10 connected to the mounting bracket 2. The buffer head 10 can be made of soft materials such as rubber and silicone. The buffer head 10 is provided in plurality and is respectively provided at the reset positions of the rocker arm 7 and the handle body 101. It is used to buffer the reset of structures such as the rocker arm 7 and the handle body 101 to prevent damage to components caused by rigid contact, and at the same time reduce noise.

[0055] The hidden door handle provided in this embodiment drives the handle body 101 to pop out through the actuator 4, and pulls the popped-out handle body 101 so that the toggle portion 102 on its rear end surface contacts the rotary block 6. The movement of the rotary block 6 can push the rocker arm 7 to rotate, thereby driving the pull rod or pull wire to move, so that the door is unlocked.

[0056] The coordination structure of this embodiment is simple. The position switching of the handle body 101 between three states can be achieved only through the coordination of the specifically constructed handle body 101 with the drive part, and the rotary block 6 and rocker arm 7 in the transmission assembly. The various components are closely coordinated with each other, the motion path is clear, the travel loss is small, and the transmission efficiency is high.

[0057] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
