Detailed Implementation

[0045] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0046] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0050] The concealed door handle according to an embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0051] like Figures 1 to 9 As shown, the concealed door handle according to an embodiment of this application includes: a base, a handle body 10, a first link 6, a second link 11, and a drive assembly.

[0052] Specifically, the base is provided with a receiving groove. The handle body 10 can extend or retract into the receiving groove. The first end of the first link 6 and the first end of the second link 11 are spaced apart in a first direction and are respectively rotatably connected to the handle body 10. The drive assembly is used to drive one of the second ends of the first link 6 and the second end of the second link 11 to move in the forward direction in the first direction, and to drive the other of the second ends of the first link 6 and the second end of the second link 11 to move in the reverse direction in the first direction, so that the handle body 10 extends or retracts into the receiving groove.

[0053] In other words, the concealed door handle according to the embodiments of this application mainly consists of a base, a handle body 10, a first link 6, a second link 11, and a drive assembly.

[0054] The base may have a receiving groove for storing the handle body 10, which can extend or retract into the receiving groove. For example, in the normal state, the handle body 10 can be stored in the receiving groove to hide it in the base, reducing wind resistance and dust in the vehicle and having an aesthetic advantage. When the user needs to open the car door, the handle body 10 can protrude from the receiving groove to facilitate the user in opening the car door by operating the handle body 10.

[0055] The side of the handle body 10 facing the receiving groove can be connected to the first end of the first link 6 and the first end of the second link 11 respectively, and the first end of the first link 6 can rotate relative to the handle body 10, and the first end of the second link 11 can also rotate relative to the handle body 10.

[0056] Furthermore, the first end of the first link 6 and the first end of the second link 11 can be spaced apart in the first direction, thereby enabling the first link 6 and the second link 11 to simultaneously drive the handle body 10 at different positions. The second end of the first link 6 and the second end of the second link 11 can extend in a direction away from the handle body 10. The second end of the first link 6 and the second end of the second link 11 can be simultaneously driven by a drive assembly. Under the drive of the drive assembly, the second end of the first link 6 can move forward in the first direction, and the second end of the second link 11 can move backward in the first direction; or, the second end of the first link 6 can move backward in the first direction, and the second end of the second link 11 can move forward in the first direction. Since the first link 6 and the second link 11 are rotatably connected to the handle body 10 respectively, the first end of the first link 6 and the first end of the second link 11 can move away from or near the base to drive the handle body 10 to extend or retract into the receiving groove.

[0057] Therefore, the concealed door handle according to the embodiment of this application, by using the drive assembly to drive the first link 6 and the second link 11 in opposite directions, can push and pull the handle body 10 to two different positions in the first direction together through the first link 6 and the second link 11, resulting in better synchronization of movement. Furthermore, the two ends of the handle body 10 are level during the process of pushing out and retracting the handle body 10, which is more aesthetically pleasing.

[0058] According to one embodiment of this application, the first link 6 and the second link 11 have the same length. Therefore, the first link 6 and the second link 11 can adopt the same structure and can be produced with a set of molds, which helps to reduce the types of parts of the concealed door handle and reduce costs.

[0059] In addition, since the first link 6 and the second link 11 have the same length, the lead of the first link 6 and the second link 11 can be set to be the same to improve the synchronization of the movement of the handle body 10.

[0060] According to some other embodiments of this application, the first link 6 and the second link 11 extend in a straight line, that is, the first link 6 and the second link 11 can be straight rods, which have the advantages of simple structure, easy manufacturing, and can withstand heavy loads and are not easily damaged.

[0061] Optionally, the first link 6 and the second link 11 can be arranged in a V-shape. For example, in the direction from the handle body 10 toward the base, the distance between the first link 6 and the second link 11 can gradually decrease, or, as... Figure 6 As shown, the distance between the first link 6 and the second link 11 can be gradually increased.

[0062] In some specific embodiments of this application, the drive assembly includes a drive rod 3 and two connecting members. The drive rod 3 extends along a first direction and is rotatably mounted on a base about its own axis. The drive rod 3 has two threaded segments arranged along the first direction, with the threads of the two threaded segments having opposite directions. The two connecting members are screwed one-to-one with the two threaded segments. One of the two connecting members is rotatably connected to the second end of the first connecting rod 6, and the other of the two connecting members is rotatably connected to the second end of the second connecting rod 11.

[0063] In other words, the drive assembly of this embodiment can mainly consist of a drive rod 3 and two connecting members. The drive rod 3 can have two threaded segments, which can be arranged along a first direction. For ease of explanation, the two connecting members can be defined as a first connecting member 4 and a second connecting member 17, and the two threaded segments as a first threaded segment 301 and a second threaded segment 302.

[0064] The first connecting member 4 can be rotatably connected to the second end of the first connecting rod 6. The first connecting member 4 may be provided with a first threaded hole 403, which can be screwed into the first threaded section 301. Thus, the first connecting member 4 can move along the drive rod 3. The second connecting member 17 can be rotatably connected to the second end of the second connecting rod 11. The second connecting member 17 may be provided with a second threaded hole 1703, which can be screwed into the second threaded section 302. Thus, the second connecting member 17 can move along the drive rod 3.

[0065] Since the threads of the first threaded segment 301 and the second threaded segment 302 are in opposite directions—for example, the first threaded segment 301 is left-handed and the second threaded segment 302 is right-handed, or the first threaded segment 301 is right-handed and the second threaded segment 302 is left-handed—when the drive rod 3 rotates, the two connecting parts can move closer to or further away from each other, so that the second end of the first connecting part 4 and the second end of the second connecting part 17 can move in opposite directions.

[0066] The first connector 4, the second connector 17, the drive rod 3, and the handle body 10 can form a four-bar linkage. Since the connectors are screwed to the threaded section, the connectors can only extend in the first direction. The second end of the first connector 4 and the second end of the second connector 17 are respectively rotatably connected to the corresponding connectors. At the same time, the distance between the first end of the first link 6 and the first end of the second link 11 remains unchanged. Therefore, the first link 6 and the second link 11 can be pushed out or retracted together to retract the handle body 10.

[0067] In this embodiment, the threaded connection between the drive rod 3 and the connecting piece forms a lead screw assembly, which not only enables synchronous driving of the first connecting piece 4 and the second connecting piece 17, but also has the advantages of high precision, good stability, strong load capacity, and low maintenance cost. In addition, using threaded transmission also helps to save installation space.

[0068] According to some optional embodiments of this application, the connector is provided with a protrusion extending in a second direction, which is perpendicular to the first direction. The protrusion is rotatably connected to the second end of the first link 6 or the second link 11. Thus, each connector can be rotatably connected to the corresponding first link 6 or second link 11 via the protrusion, which has the advantages of simple structure, small space occupation, and flexible arrangement.

[0069] In some alternative embodiments, for ease of explanation, the side of the handle body 10 facing the receiving groove can be defined as the back of the handle body 10, and the side of the handle body 10 away from the receiving groove can be defined as the front of the handle body 10. The side of the handle body 10 may have two connecting posts extending along the thickness direction of the handle body 10. The two connecting posts may be spaced apart along a first direction. One connecting post may have a first hole 1001, and the other connecting post may have a second hole 1002. The first end of the first connecting rod 6 may have a third hole 601, the second end of the first connecting rod may have a fourth hole 602, the first end of the second connecting rod 11 may have a fifth hole 1101, and the second end of the second connecting rod may have a sixth hole 1102. The first hole 1001, the second hole 1002, the third hole 601, the fourth hole 602, the fifth hole 1101, and the sixth hole 1102 may be parallel to each other.

[0070] The concealed door handle also includes two fixed shafts 7, one of which can pass through the first hole 1001 and the third hole 601, and the other of which can pass through the second hole 1002 and the fifth hole 1101, so that the first link 6 and the second link 11 are rotatably connected to the handle body 10 respectively.

[0071] The first connector 4 may be provided with a first protrusion 402, which can be rotatably connected to the fourth hole 602 on the first connecting rod 6. The second connector 17 may be provided with a second protrusion 1702, which can be rotatably connected to the sixth hole 1102 on the second connecting rod 11.

[0072] Additionally, each connector may have two protrusions, which can form ears on the connector. The two protrusions may be arranged opposite to each other on the connector. The second end of the first connecting rod 6 may have two first plates, each plate having a fourth hole 602 extending through its own thickness. The second end of the second connecting rod may have two second plates, each second plate having a sixth hole 1102 extending through its own thickness.

[0073] According to some other embodiments of this application, the base is provided with a guide extending in a first direction, and the connector is provided with a mating part. The guide is connected to the mating part and guides the connector to move in the first direction.

[0074] By cooperating with the guide and the mating part, the direction of the linear movement of the connector can be restricted, so as to avoid the connector from deviating during the movement and affecting the position of the corresponding first link 6 or second link 11, thereby affecting the position of the handle body 10 and ruining the aesthetics of the concealed door handle.

[0075] Optionally, the guide component may include, but is not limited to, guide rod, guide hole and guide groove, and the mating part may include, but is not limited to, guide block and guide shaft, all of which can meet the guiding and limiting requirements of the connecting part.

[0076] The mating part on the first connector 4 can be the first mating part 401, and the mating part on the second connector 17 can be the second mating part 1701.

[0077] In some specific embodiments of this application, such as Figure 1 As shown, the guide is a guide groove, and the mating part is a protrusion. The protrusion is located in the guide groove and can move along the guide groove.

[0078] Specifically, the guide groove can be arranged along the first direction on the side of the base facing the handle body 10, and the side of the connector away from the handle body 10 can be provided with a protrusion. The protrusion can be inserted into the guide groove and can move along the guide groove. In this embodiment, the structure of the guide groove and the protrusion is simple, easy to manufacture, and highly reliable.

[0079] There can be two guide grooves, namely a first guide groove 204 and a second guide groove 205. The first guide groove 204 is connected to the protrusion on the first connector 4, and the second guide groove 205 is connected to the protrusion on the second connector 17.

[0080] According to some optional embodiments of this application, the drive assembly includes an actuator 16, which is disposed at one end of the drive rod 3. The actuator 16 has an output shaft 1601, which is coaxially connected to the drive rod 3 and is used to drive the drive rod 3 to rotate about its own axis.

[0081] Specifically, the actuator 16 can be arranged at one end of the drive rod 3, which helps to reduce the overall thickness of the concealed door handle. A coupling sleeve 15 can be provided between the output shaft 1601 of the actuator 16 and one end of the drive rod 3. By locking the coupling sleeve 15 with a tap 13, the output shaft 1601 and the drive rod 3 can rotate coaxially.

[0082] Actuator 16 can be connected to and controlled by the vehicle's electronic control system. When the electronic control system sends a command to actuator 16, actuator 16 can control the rotation direction of drive rod 3 by controlling the forward and reverse rotation of output shaft 1601, and then control the extension and retraction of handle body 10 through first link 6 and second link 11.

[0083] According to some other embodiments of this application, the base is provided with two mounting holes, which are spaced apart along a first direction. The drive rod 3 is rotatably connected to the two mounting holes, and two connectors are located between the two mounting holes.

[0084] Therefore, the two mounting holes can limit the movement of the connectors close to each other, that is, the two mounting holes define an extreme position of the connectors on the drive rod 3, preventing the connectors from separating from the drive rod 3. The two mounting holes can be a first mounting hole 201 and a second mounting hole 202, respectively.

[0085] Optionally, a bearing 14 may be provided in the mounting hole connected to the end of the drive rod 3 near the actuator 16. The bearing 14 may be sealed in the mounting hole by the bearing cover 12. The drive rod 3 may be connected to the bearing 14 to reduce the frictional resistance experienced by the drive rod 3 during rotation.

[0086] In some specific embodiments of this application, the base is provided with a second limiting part and a first limiting part 208, and the handle body 10 is movable between a first state and a second state. When the handle body 10 is in the first state, the handle body 10 is housed in the receiving groove, and the handle body 10 abuts against the first limiting part 208 for limitation; when the handle body 10 is in the second state, the handle body 10 extends out of the receiving groove, and at least one of the first connecting rod 6 and the second connecting rod 11 abuts against the second limiting part for limitation.

[0087] When the handle body 10 switches from the first state to the second state, the drive rod 3 can rotate in the forward direction. The first connecting rod 6 and the second connecting rod 11 push the handle body 10 out of the receiving groove until the handle body 10 extends to a certain position. At this time, the first connecting rod and / or the second connecting rod can contact the first limiting part 208 and be limited. At this time, the actuator 16 has high resistance and the feedback current exceeds the standard. The actuator 16 can stop working. The position of the handle body 10 at this time is an extreme position of the handle body 10.

[0088] When the handle body 10 switches from the second state to the first state, the drive rod 3 can rotate in the opposite direction. The first link 6 and the second link 11 will retract the handle body 10 into the receiving groove until the handle body 10 is retracted to a certain position. At this time, the handle body 10 can contact the second limiting part and be limited. At this time, the actuator 16 has high resistance and the feedback current exceeds the standard. The actuator 16 can stop working. The position of the handle body 10 at this time is the other extreme position of the handle body 10.

[0089] In this embodiment, by setting the first limiting part 208 and the second limiting part, the extreme position of the handle body 10 can be controlled by physical means, which has the advantages of low cost and high reliability.

[0090] In some specific embodiments of this application, the first limiting part 208 is disposed between the second end of the first connecting rod 6 and the second end of the second connecting rod 11. The side of the first limiting part 208 facing the handle body 10 is formed as a first limiting surface 209. The side of the handle body 10 facing the mounting base 2 is provided with a mating surface 901. When the handle body 10 is in the first state, the mating surface 901 abuts against the first limiting surface 209.

[0091] Specifically, the first limiting part 208 can be located between the two connecting parts to avoid interfering with the pushing and pulling of the first link 6 and the second link 11 on the handle body 10.

[0092] The first limiting part 208 can be a boss provided on the base. The boss can protrude toward the handle body 10. The side of the boss facing the handle body 10 can be formed as the first limiting surface 209. The side of the handle body 10 facing the base can be provided with a mating surface 901. The mating surface 901 can abut against the first limiting surface 209 to limit the handle body 10.

[0093] Optionally, the mating surface 901 and the first limiting surface 209 can be planes.

[0094] According to some optional embodiments of this application, the second limiting part has a second limiting surface, which is inclined relative to the first direction. When the handle body 10 is in the second state, the second limiting surface abuts against the outer peripheral surface of the first link 6 or the second link 11.

[0095] Specifically, the second limiting surface can be an inclined surface provided on the second limiting part, and the second limiting surface can be inclined relative to the first direction, and the second limiting surface can be parallel to the second direction. When the handle body 10 is in the second state, the first connecting rod 6 abuts against the second limiting surface, and the extension direction of the first connecting rod 6 can be parallel to the second limiting surface; or, the second connecting rod 11 abuts against the second limiting surface, and the extension direction of the first connecting rod 6 can be parallel to the second limiting surface.

[0096] According to some other embodiments of this application, there are two second limiting parts, which are spaced apart along the first direction. When the handle body 10 is in the second state, one of the two second limiting parts abuts against the first connecting rod 6, and the other of the two second limiting parts abuts against the second connecting rod 11.

[0097] Specifically, the two second limiting portions can be spaced apart at both ends of the first limiting portion 208 along the first direction, meaning the first limiting portion 208 can be located between the two second limiting portions. Additionally, the two second limiting portions can be located between the two connecting members. The two second limiting portions can respectively abut against the corresponding first link 6 or second link 11 to achieve limitation.

[0098] In this embodiment, two second limiting parts are set to limit the first link 6 and the second link 11 respectively, which can provide double safety guarantee. As long as one of the two second limiting parts works normally, the limiting function can be realized, which helps to reduce maintenance costs and improve the stability of the operation of the hidden door handle.

[0099] The second limiting surface on one of the two second limiting parts can be a left inclined surface 206, and the second limiting surface on the other of the two second limiting parts can be a right inclined surface 207.

[0100] According to some optional embodiments of this application, the base includes: an upper cover 9, a lower cover 1, and a mounting base 2. The upper cover 9 and the lower cover 1 are arranged along the extension direction of the rotation center line of the first connecting rod 6, and the upper cover 9 and the lower cover 1 are connected and define a receiving groove. The mounting base 2 is received in the receiving groove and located on the side of the handle body 10 near the bottom of the receiving groove, and the drive assembly is located on the mounting base 2.
