Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a door handle device that can be used in automobiles. Background Technology

[0002] With the widespread adoption of automotive electrification and advancements in manufacturing processes, the design of automotive exterior door handles is constantly evolving and innovating. Hidden door handles, as one such design trend, reduce wind resistance, a crucial factor when vehicles are traveling at high speeds. By reducing protruding components on the vehicle body, hidden door handles lower the drag coefficient, thereby improving the vehicle's aerodynamic performance and ultimately its energy efficiency—a particularly important aspect in the field of new energy vehicles.

[0003] The design of concealed door handles hides traditional protruding door handles within the vehicle body, making them an integral part of the vehicle. After the vehicle is unlocked, the door handles automatically pop out or unfold from the body to allow the user to open the door. The pre-unfolded state refers to the stage after the door handle is unlocked but before it has been fully unfolded by the user.

[0004] The pre-deployment of concealed door handles typically relies on the vehicle's electronic control system and sensors. When the vehicle receives an unlock signal, the electronic control system activates the door handle's motor or drive mechanism, causing the door handle to begin moving from the concealed position to the deployed position. At this time, the door handle is still in a partially concealed or half-deployed state, i.e., the pre-deployed state.

[0005] However, compared to protruding door handles, concealed door handles require not only a locking mechanism inside the door but also a dedicated motor and drive mechanism for unfolding the handle, making the door structure more complex and space-consuming. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem in the prior art that, compared with the protruding door handle, the concealed door handle needs to be able to move from the concealed position to the unfolded position. This results in not only the need to set up a door lock structure inside the car door, but also the need to add a motor and drive structure dedicated to unfolding the handle, which makes the structure inside the car door cumbersome and takes up a lot of space.

[0007] To solve the above-mentioned technical problems, the present invention discloses a car door handle device. This car door handle device shares the drive structure for locking the car door with the drive structure for extending the hidden car door handle. Under the premise that the car door handle can be extended electrically, the number of parts in the transmission structure inside the car door is reduced. Moreover, the structure for opening and unlocking the drive handle body inside the car door handle device is relatively compact, which is convenient for assembly inside the car door.

[0008] Specifically, this door handle device includes a mounting base, and a handle body, a drive assembly, and an unlocking assembly mounted on the mounting base. The mounting base is used to assemble this door handle device onto the door. It can be a separate component that is fitted into a mounting slot at a corresponding position on the door, or it can be a component of the door itself, to assemble the handle body, drive assembly, and unlocking assembly onto the door.

[0009] The handle body is movably mounted in the mounting base and can be switched between an unfolded state and a folded state.

[0010] In this design, the outer wall of the handle body in the folded state is closer to the outer surface of the door than the outer wall of the handle body in the unfolded state. This reduces protruding parts on the vehicle body, lowers the drag coefficient, improves the vehicle's aerodynamic performance, and reduces energy consumption at high speeds. Of course, the outer wall of the handle body in the folded state can also protrude slightly from the outer surface of the door, or be slightly recessed.

[0011] The handle body, in the unfolded state, extends out of the outer surface of the car door. Specifically, the handle body can rotate around a pivot at one end toward the side away from the car door. The handle body can also extend out of the outer surface of the car door along a guide structure perpendicular to the outer surface of the car door, thus making it easy for the operator to pull the handle body from outside the car to unlock it.

[0012] The inner side of the handle body is provided with a protrusion, which is used to drive the drive component and the unlocking component respectively. The drive component drives the protrusion of the handle body, which can switch the handle body from a folded state to an unfolded state. When the handle body is in the unfolded state, and the operator pulls the handle body, the protrusion can drive the unlocking component to unlock the handle body.

[0013] Specifically, the drive assembly includes a drive component mounted on the mounting base and a transmission component disposed at the output end of the drive component. The drive component can drive the transmission component to switch between a drive position and a non-drive position. The transmission component cooperates with the protrusion of the handle body and the unlocking component.

[0014] The unlocking component includes an unlocking member connected to the unlocking cable, and a linkage member for linking the unlocking member and the protrusion. The linkage member can switch between a first position and a second position. When the linkage member is in the first position, it is connected to the limiting part and separated from the unlocking member and / or the protrusion. For example, the linkage member is separated from both the protrusion and the unlocking member; or the linkage member is connected to the protrusion and separated from the unlocking member; or the linkage member is separated from the protrusion and connected to the unlocking member. That is, when the linkage member is in the first position, the power transmission between the protrusion and the unlocking member is interrupted.

[0015] The linkage in the second position is separated from the limiting part and is connected to both the unlocking part and the protrusion. That is, the linkage in the second position can transmit the power of the protrusion to the unlocking part.

[0016] During use, the handle body is usually in a folded state. In order for the operator to pull the handle body to open the car door from the outside, the drive component drives the transmission component to move from the non-drive position to the drive position. The transmission component drives the protrusion on the handle body, so that the handle body switches from the folded state to the unfolded state. At the same time, the transmission component separates from the linkage component, and the linkage component moves from the first position to the second position.

[0017] Furthermore, the operator can pull the handle body, causing the protruding part to drive the linkage in the second position, and then the unlocking part to pull the unlocking cable to unlock the door.

[0018] In summary, the door handle device provided by this invention cleverly incorporates a driving component and an unlocking component. When the driving component drives the transmission component to switch the handle body to the unfolded state, it simultaneously drives the linkage component to move to a second position. This allows the power of the protruding part to be transmitted to the unlocking component. In other words, when the driving component switches the transmission component from the non-driving position to the driving position, it not only unfolds the handle body but also unlocks it. This ensures that the handle body can drive the unlocking component to unlock in the unfolded state. Even if the handle body is forcibly pulled out to the unfolded position by external force, the linkage component, being in the first position, cannot transmit the power of the protruding part to the unlocking component to unlock, thus improving the locking security of the door.

[0019] Specifically, the transmission component has a transmission part and a limiting part. The transmission part is used to cooperate with the protrusion of the handle body, and the limiting part is used to cooperate with the unlocking component.

[0020] When the transmission component is in a non-driving position, the limiting part connects with the linkage component, causing the linkage component to be fixed in the first position.

[0021] When the driving component drives the transmission component to move from the non-driving position to the driving position, the transmission component drives the protrusion and the handle body extends outward toward the door. At the same time, the limiting part separates from the linkage component, and the linkage component moves from the first position to the second position.

[0022] Furthermore, to avoid excessive transmission load on the linkage, the unlocking assembly also includes an intermediate part movably disposed in the mounting base, located between the linkage and the protrusion.

[0023] Specifically, an intermediate component is provided between the linkage and the protrusion to transmit the power of the protrusion to the linkage through the intermediate component. The protrusion of the handle body in the unfolded state is connected to the intermediate component, and the intermediate component is connected to the linkage in the second position. This allows the protrusion of the handle body in the unfolded state to be linked to the linkage in the second position through the intermediate component, so that the linkage can drive the unlocking component to pull the unlocking cable.

[0024] In this implementation, the intermediate component can distribute the load of the linkage components, improving the overall safety of power transmission and enabling the unlocking assembly to have a longer service life and higher reliability. Simultaneously, the addition of the intermediate component allows for adjustment of the transmission arm, thus regulating the unlocking stroke of the unlocking component.

[0025] An embodiment of the present invention also discloses an automobile, including a door, wherein the door is equipped with any of the above-described door handle devices.

[0026] The car doors of this type of vehicle are equipped with the aforementioned door handle device. Through a set of drive components, the handle body can not only switch between folded and unfolded states, but also unlock itself, simplifying the structure of the door lock and making the door structure more compact.

[0047] As noted in the background section, concealed door handles, compared to protruding door handles, require not only a locking mechanism within the car door but also an additional motor and drive mechanism for handle unfolding, resulting in a cumbersome and space-consuming interior structure. To address this, the present invention proposes a car door handle device. This device includes a mounting base, a handle body mounted on the mounting base, a drive assembly, and an unlocking assembly. The mounting base is fixed to the car door, the handle body is movably connected to the mounting base, and the handle body can switch between an unfolded and folded state. A protrusion is provided on the inner side of the handle body. The drive assembly includes a drive component and a transmission component, and the unlocking assembly includes an unlocking component and a linkage component. The transmission component cooperates with the protrusion and linkage component of the handle body. The drive component of this door handle device is connected to the handle body and the unlocking component via a transmission. The drive component causes the handle body to switch from a folded state to an unfolded state. Furthermore, the transmission linkage is connected to the protrusion and the unlocking component. The protrusion of the handle body can be linked to the unlocking component through the linkage to unlock, thus integrating the door locking / unlocking functions into the door handle device, making the structure inside the door more compact.

[0048] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0049] like Figures 1-3 As shown, this door handle device 10 includes a mounting base, and a handle body 100, a drive assembly 200, and an unlocking assembly 300 mounted on the mounting base. The mounting base, used to assemble this door handle device 10 onto a vehicle door, can be a separate component, such as one mounted in a corresponding mounting slot on the door, or it can be a component of the door itself, used to assemble the handle body 100, drive assembly 200, and unlocking assembly 300 onto the door. It should be noted that the structure of the mounting base is not shown in the figure, and this embodiment does not specifically limit its structure.

[0050] Furthermore, the handle body 100 is movably mounted in the mounting base and can be switched between an unfolded state and a folded state.

[0051] In this design, the outer wall of the handle body 100 in the folded state is closer to the outer surface of the door than the outer wall of the handle body 100 in the unfolded state. This reduces protruding parts on the vehicle body, lowers the drag coefficient, improves the vehicle's aerodynamic performance, and reduces energy consumption at high speeds. Of course, the outer wall of the handle body 100 in the folded state can also protrude slightly beyond the outer surface of the door.

[0052] The handle body 100, in its unfolded state, extends out of the outer surface of the vehicle door. Specifically, the handle body 100, in its folded state, can rotate around a pivot at one end toward the side opposite to the vehicle door. The handle body 100, also in its folded state, can extend translatably out of the outer surface of the vehicle door along a guide structure perpendicular to the outer surface of the door, thus facilitating the operator's hand to pull the handle body 100 from outside the vehicle to unlock it. Those skilled in the art can design according to actual conditions and specific needs; this embodiment does not impose specific limitations in this regard.

[0053] The inner side of the handle body 100 is provided with a protrusion 110, which is used to drive the drive component 200 and the unlocking component 300 respectively. The drive component 200 drives the protrusion 110 of the handle body 100, which can switch the handle body 100 from a folded state to an unfolded state. When the handle body 100 is in the unfolded state, and the operator pulls the handle body 100, the protrusion 110 can drive the unlocking component 300 to unlock.

[0054] The drive assembly 200 includes a drive member 210 mounted on the mounting base and a transmission member 220 disposed at the output end of the drive member 210. The drive member 210 can drive the transmission member 220 to switch between a drive position and a non-drive position. The transmission member 220 cooperates with the protrusion 110 of the handle body 100 and the unlocking assembly 300.

[0055] The unlocking component 300 includes an unlocking member 310 connected to the unlocking cable and a linkage member 320 for linking the unlocking member 310 and the protrusion 110. The linkage member 320 can switch between a first position and a second position. When the linkage member 320 is in the first position, it is connected to the limiting part 222 and separated from the unlocking member 310 and / or the protrusion 110. For example, the linkage member 320 is separated from both the protrusion 110 and the unlocking member 310; or the linkage member 320 is connected to the protrusion 110 and separated from the unlocking member 310; or the linkage member 320 is separated from the protrusion 110 and connected to the unlocking member 310. That is, the linkage member 320 in the first position interrupts the power transmission between the protrusion 110 and the unlocking member 310.

[0056] The linkage 320 in the second position is separated from the limiting part 222 and is connected to both the unlocking part 310 and the protrusion 110. That is, the linkage 320 in the second position can transmit the power of the protrusion 110 to the unlocking part 310.

[0057] During use, the handle body 100 is usually in a folded state. In order to facilitate the operator to pull the handle body 100 to open the car door from the outside, the drive component 210 drives the transmission component 220 to move from the non-drive position to the drive position. The transmission component 220 is driven by the protrusion 110 on the handle body 100, so that the handle body 100 switches from the folded state to the unfolded state. At the same time, the transmission component 220 separates from the linkage component 320, and the linkage component 320 moves from the first position to the second position.

[0058] Furthermore, the operator can pull the handle body 100, causing the protrusion 110 to drive the linkage 320 in the second position, and then the unlocking component 310 to pull the unlocking cable to unlock the car door.

[0059] Therefore, the door handle device 10 provided by this invention cleverly sets up a drive component 200 and an unlocking component 300, so that when the drive component 210 drives the transmission component 220 to switch the handle body 100 to the unfolded state, it can simultaneously drive the linkage component 320 to move to the second position, thereby transmitting the power of the protrusion 110 to the unlocking component 310. That is, when the drive component 210 drives the transmission component 220 to switch from the non-drive position to the drive position, it can not only unfold the handle body 100, but also unlock it. Thus, in the unfolded state, the handle body 100 can transmit the power of the unlocking component 310 to unlock. Even if the handle body 100 is forcibly pulled out to the unfolded position by external force, the linkage component 320 is in the first position and cannot transmit the power of the protrusion 110 to the unlocking component 310 to unlock, thereby improving the locking security of the door.

[0060] The following is a detailed description of each component of the door handle assembly 10.

[0061] Regarding the handle body 100, as shown in Figure 1, in this embodiment, the handle body 100 is a strip-shaped plate structure, which is movably mounted on the mounting base and can switch between a folded state and an unfolded state. The protrusion 110 provided on the handle body 100 is used to transmit the power of the handle body 100 to the unlocking component 300, or to be driven by the driving component 200. Of course, the specific structure of the handle body 100 is not limited to a strip-shaped plate structure, but can also be a spindle-shaped structure or a ring structure. Those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not specifically limit it in this way.

[0062] The outer wall of the handle body 100 in the folded state is flush with the outer surface of the door, or slightly protrudes from the outer surface of the door, or slightly recessed into the outer surface of the door, thereby reducing the drag coefficient of the vehicle body.

[0063] The handle body 100, in its unfolded state, extends out of the outer surface of the vehicle door. Specifically, one side of the handle body 100 may extend out of the outer surface of the vehicle door, or the entire handle body 100 may extend out of the outer surface of the vehicle door, thus facilitating the operator's hand to pull the handle body 100 from outside the vehicle to unlock it. Furthermore, for the operator's hand grip, a grip groove adapted to the fingers is formed on the inner side of the handle body 100 near the vehicle door.

[0064] The process of switching the handle body 100 from a folded state to an unfolded state can be either a rotating type or a flat type.

[0065] Optionally, such as Figure 1 , Figure 3 as well as Figure 5 and Figure 6 As shown, in one embodiment, taking the handle body 100 extending out of the outer surface of the door as an example, one end of the handle body 100 near the inner side of the mounting base is rotatably connected to the mounting base via the mounting shaft 20.

[0066] When the handle body 100 in the folded state switches to the unfolded state, it swings around the mounting shaft 20 in a direction away from the mounting base, and the other end of the handle body 100 in the unfolded state protrudes from the outer surface of the door. Of course, in this embodiment, the rotation of the handle body 100 around the mounting shaft 20 is achieved by the transmission component 220 of the drive assembly 200 transmitting power to the protrusion 110 on the handle body 100.

[0067] In another alternative embodiment, taking the handle body 100 as an example where the entire handle body 100 extends out of the outer surface of the door, the handle body 100 is slidably mounted on the mounting base via a plurality of guide structures (e.g., guide rods) perpendicular to the outer surface of the door.

[0068] When the handle body 100 in the folded state switches to the unfolded state, the handle body 100 slides along the guide rod toward the direction away from the car door. The handle body 100 in the unfolded state protrudes from the outer surface of the car door, and the grip groove on the inner side of the handle body 100 is located on the outer side of the car door.

[0069] Of course, the specific structure of the handle body 100 is not limited to the structure in the above embodiments. Those skilled in the art can design it according to actual conditions and specific needs. This embodiment does not make specific limitations in this regard.

[0070] like Figures 1-3 As shown, in one embodiment, the transmission member 220 has a transmission part 221 and a limiting part 222. The transmission part 221 is used to cooperate with the protrusion 110 of the handle body 100, and the limiting part 222 is used to cooperate with the unlocking component 300.

[0071] When the transmission component 220 is in the non-drive position and the handle body 100 is in the folded state, the limiting part 222 of the transmission component 220 is connected to the linkage component 320, so that the linkage component 320 is fixed in the first position.

[0072] In this embodiment, the unlocking component 300 includes an unlocking member 310 and a linkage member 320. The unlocking member 310 is connected to the unlocking cable and will pull the unlocking cable during operation to unlock the device. The linkage member 320 is used to transmit power between the protrusion 110 and the unlocking member 310.

[0073] Specifically, the linkage 320 can be connected to the limiting part 222 on the transmission member 220 (in the non-driving position), thereby being limited to the first position. At this time, the linkage 320 is separated from at least one of the protrusion 110 and the unlocking member 310, and the power of the protrusion 110 cannot be transmitted to the unlocking member 310 through the linkage 320. Even if the handle body 100 is pulled, the door cannot be unlocked. When the linkage 320 is separated from the limiting part 222 on the transmission member 220 (in the driving position), the linkage 320 switches to the second position. The linkage 320 is connected to both the protrusion 110 and the unlocking member 310, and the power of the protrusion 110 can be transmitted to the unlocking member 310 through the linkage 320.

[0074] Furthermore, such as Figure 1 As shown, in order to avoid excessive transmission load received by the linkage 320, the unlocking assembly 300 also includes an intermediate member 330 movably disposed on the mounting base, the intermediate member 330 being located between the linkage 320 and the protrusion 110.

[0075] Specifically, an intermediate member 330 is provided between the linkage member 320 and the protrusion 110 to transmit the power of the protrusion 110 to the linkage member 320 through the intermediate member 330. The protrusion 110 of the handle body 100 in the unfolded state is connected to the intermediate member 330 through a transmission connection. Furthermore, the intermediate member 330 is connected to the linkage member 320 located in the second position through a transmission connection. This allows the protrusion 110 of the handle body 100 in the unfolded state to be linked to the linkage member 320 located in the second position through the intermediate member 330, so that the linkage member 320 can drive the unlocking member 310 to pull the unlocking cable through the linkage member 320.

[0076] When the driving member 210 drives the transmission member 220 to move from the non-driving position to the driving position, the transmission part 221 drives the protrusion 110 and links the handle body 100 to extend outward toward the door, so that the handle body 100 switches from the folded state to the unfolded state. In addition, the limiting part 222 separates from the limiting part 322 of the linkage member 320, and the linkage member 320 moves from the first position to the second position. The protrusion 110 of the handle body 100 in the unfolded state can link the linkage member 320 located in the second position, so that the linkage member 320 drives the intermediate part 330 and the unlocking part 310, and the unlocking part 310 pulls the unlocking cable to unlock.

[0077] In this embodiment, the intermediate component 330 can distribute the load of the linkage 320, improving the overall safety of power transmission and enabling the unlocking component 300 to have a longer service life and higher reliability. Simultaneously, the addition of the intermediate component 330 allows for adjustment of the transmission arm, thereby regulating the unlocking stroke of the unlocking component 310.

[0078] Optionally, such as Figure 1 As shown, in one embodiment, the unlocking member 310 is configured as a first swing arm 311, the upper end of the first swing arm 311 is swayably mounted on the mounting base via a first connecting shaft (not shown in the figure), and the lower end of the first swing arm 311 is connected to the unlocking cable.

[0079] The linkage 320 is configured as a linkage rod 323. The linkage rod 323 is swayably mounted on the first swing arm 311 via a third connecting shaft (not shown in the figure). The linkage rod 323 is located on the side of the first swing arm 311 away from the protrusion 110 of the handle body 100. One end of the linkage rod 323 is provided with a limited part 322 that cooperates with the limiting part 222, and the other end is provided with a linkage part 321.

[0080] The intermediate component 330 is configured as a second swing arm 331. The upper end of the second swing arm 331 is swayably mounted on the mounting base via a second connecting shaft (not shown in the figure). The first swing arm 311 and the second swing arm 331 are stacked along the direction of the rotation axis. Furthermore, the linkage component 320 and the protrusion 110 of the handle body 100 are respectively provided on the opposite sides of the first swing arm 311 and the second swing arm 331.

[0081] The first swing arm 311 has a first driven part 312 on the side corresponding to the linkage member 320, and the second swing arm 331 has a second driven part 332 on the side corresponding to the linkage member 320. The linkage part 321 of the linkage member 320 located in the second position is connected to the first driven part 312 and the second driven part 332 respectively.

[0082] Furthermore, the second swing arm 331 has a driven part 333 adapted to the protrusion 110 on the side corresponding to the protrusion 110, and the protrusion 110 of the handle body 100 in the unfolded state abuts against the driven part 333.

[0083] It should be noted that the linkage rod 323 is limited to the first position by the limiting part 222 on the transmission member 220. When the limiting part 222 on the transmission member 220 separates from the linkage rod 323, in order to ensure that the linkage rod 323 can move toward the second position, an elastic reset member 324 is sleeved on the third connecting shaft. The reset member 324 applies a restoring force to the linkage rod 323 to swing from the first position toward the second position.

[0084] Furthermore, in one embodiment, such as Figure 1 As shown, the limiting part 322 is configured as a limiting pin 326, and the linkage part 321 is configured as a linkage pin 325 adapted to the first linkage part 312 and the second linkage part 332.

[0085] Specifically, the linkage rod 323 has a mounting hole on the side near the limited part 322, the third connecting shaft is sleeved in the mounting hole and connected to the first swing arm 311, and the reset member 324 is a return torsion spring sleeved in the mounting hole.

[0086] It should be noted that in this embodiment, the axial directions of the first connecting shaft, the second connecting shaft, and the third connecting shaft are parallel to each other and are all perpendicular to the axial direction of the mounting shaft 20.

[0087] Alternatively, in one embodiment, such as Figure 1 and Figure 2 As shown, the axes of the first connecting shaft and the second connecting shaft coincide, and the first swing arm 311 and the second swing arm 331 can swing around the same axis. The first linked part 312 is configured as a first linked groove 313 that is adapted to the corresponding part of the linkage member 320, and the second linked part 332 is configured as a second linked groove 334 that is adapted to the corresponding part of the linkage member 320. Looking along the axial direction of the connecting shaft, the position of the first linked groove 313 on the first swing arm 311 and the position of the second linked groove 334 on the second swing arm 331 are aligned.

[0088] The driven part 333 is configured as a driven groove 335 that mates with the protrusion 110 of the handle body 100.

[0089] When the protrusion 110 of the handle body 100 in the unfolded state abuts against the driven groove 335, and the linkage pin 325 of the linkage member 320 is inserted into the first driven groove 313 and the second driven groove 334, the protrusion 110 of the handle body 100 pushes the second swing arm 331. The second swing arm 331 acts on the linkage part 321 of the linkage member 320 through the second driven groove 335, and the linkage pin 325 of the linkage member 320 acts on the first driven groove 335 of the first swing arm 311, thereby transmitting power to the first swing arm 311, causing the first swing arm 311 and the second swing arm 331 to swing together.

[0090] It should be noted that in this embodiment, the second swing arm 331 is located on the side of the first swing arm 311 away from the handle body 100. That is, the driven groove 335 on the second swing arm 331 abuts against the end of the protrusion 110 away from the handle body 100. Compared with the protrusion 110 directly abutting against the first swing arm 311, the swing angle of the first swing arm 311 is larger through the linkage of the second swing arm 331.

[0091] Of course, in another embodiment, the second swing arm 331 is located on the side of the first swing arm 311 near the handle body 100, that is, the driven groove 335 on the second swing arm 331 abuts against the end of the protrusion 110 near the handle body 100, thereby reducing the swing angle of the first swing arm 311.

[0092] Furthermore, in order to improve the transmission stability between the linkage pin 325 and the first driven groove 313 and the second driven groove 334, such as Figure 2 and Figure 4 As shown, the first swing arm 311 forms an outwardly protruding first extended sidewall 314 on one side of the first driven groove 313, and the second swing arm 331 forms an outwardly protruding second extended sidewall 336 on the other side of the second driven groove 334. It should be noted that the first extended sidewall 314 is formed on the side where the linkage pin 325 applies a thrust to the first driven groove 313 (i.e.,...). Figure 4 The second extended sidewall 336 is formed on the side where the second linkage groove 334 applies a thrust to the linkage pin 325 (i.e., the upper side of the middle section). Figure 4 (The lower side of the middle).

[0093] Of course, in another alternative embodiment, compared with the above embodiment, there is no need to set a second swing arm 331 between the first swing arm 311 and the linkage rod 323. An extension is provided on the side of the linkage pin 325 near the protrusion 110. When the limited part 322 of the linkage rod 323 separates from the limited part 222 on the transmission member 220 and moves to the second position, the linkage pin 325 of the linkage rod 323 is embedded in the first linked groove 313 of the first swing arm 311, and the extension on the linkage pin 325 abuts against the protrusion 110 of the handle body 100 in the unfolded state. When the operator pulls the handle body 100, the protrusion 110 pushes the extension and, through the linkage pin 325, links the first swing arm 311 to swing, thereby pulling the unlocking cable to unlock.

[0094] Regarding the specific structure of the unlocking component 300, those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not impose specific limitations on it.

[0095] like Figure 1 As shown, the drive assembly 200 includes a drive member 210 mounted on the mounting base and a transmission member 220 disposed at the output end of the drive member 210. The drive member 210 can drive the transmission member 220 to switch between a drive position and a non-drive position, so that the transmission member 220 can link the handle body 100 and the unlocking assembly 300 through the transmission part 221 and the limiting part 222 respectively.

[0096] Specifically, the driving component 210 is an actuator that outputs power along the length of the handle body 100, and the transmission component 220 is configured as a transmission rod 223. The transmission rod 223 is provided with a transmission part 221 and a limiting part 222 spaced apart along the axial direction. The transmission part 221 abuts against the side of the protrusion 110 near the actuator (e.g., Figure 1 (right side of the middle), the limiting part 222 abuts against the side of the limiting pin 326 away from the actuator (e.g., the right ... Figure 1 (Left side of the image). It should be noted that the actuator can be a linear motor commonly used in this field, and it communicates with the vehicle's controller to control the actuator's movements.

[0097] When the operator needs to open the car door from the outside, he sends a corresponding command to the controller. The controller controls the actuator to drive the transmission rod 223 to move along its axis toward the side away from the actuator. The transmission part 221 pushes the protrusion 110, and the handle body 100 extends out of the outer surface of the car door and is in an unfolded state. The limiting part 222 disengages from the limiting pin 326, and the linkage rod 323 swings from the first position toward the second position.

[0098] Optionally, in one embodiment, one end of the handle body 100 near the inner side of the mounting base is rotatably connected to the mounting base via the mounting shaft 20, the transmission part 221 is configured as a push block 224 that abuts against the wall of the protrusion 110 near the actuator; the limiting part 222 is configured as a limiting wall 225 that abuts against the side of the limiting pin 326 away from the actuator.

[0099] In another alternative embodiment, the handle body 100 is slidably mounted on the mounting base via multiple guide structures (e.g., guide rods) perpendicular to the outer surface of the door. The protrusion 110 of the handle body 100 is configured as a wedge-shaped block, and the transmission part 221 is configured as a push block that is adapted to and abuts against the wall of the wedge-shaped block near the actuator. The actuator drives the transmission rod 223 to move along its axial direction toward the side away from the actuator. The push block pushes the inclined wall of the wedge-shaped block, converting the translation of the transmission rod 223 along the axial direction into the movement of the handle body 100 in a direction perpendicular to the outer surface of the door, thereby causing the handle body 100 to slide to the unfolded state along the direction of the multiple guide rods.

[0100] Of course, those skilled in the art can design the specific structure of the driving component 200 according to actual conditions and specific needs, and this embodiment does not impose specific limitations on it.

[0101] In summary, the present invention provides a car door handle device 10, and the car door handle device 10 will be described below in conjunction with the working process.

[0102] like Figure 1 and Figure 2 As shown, the handle body 100 is initially in a folded state, at which time the handle body 100 is along... Figure 3 Extending horizontally and flush with the outer surface of the door, the protrusion 110 of the handle body 100 extends along... Figure 3 Extending vertically, the transmission rod 223 of the drive assembly 200 is located in... Figure 1 In the non-drive position shown, the linkage 323 provided on the first swing arm 311 is located at... Figure 1 In the second position, the upper limit pin 326 of the linkage rod 323 cooperates with the limit wall 225 on the transmission rod 223, and the lower linkage pin 325 of the linkage rod 323 is separated from the first linkage groove 313 of the first swing arm 311 and the second linkage groove 334 of the second swing arm 331.

[0103] Furthermore, such as Figure 4 As shown, the actuator pushes the transmission rod 223 along its axial direction, and the push block 224 on the transmission rod 223 pushes the protrusion 110 on the handle body 100, causing one end of the handle body 100 to rotate around the mounting shaft 20. Figure 5As shown, the other end of the handle body 100 protrudes from the outer surface of the door, and the protruding portion 110 of the handle body 100 abuts against the driven groove 335 of the second swing arm 331. Simultaneously, the limiting wall 225 on the transmission rod 223 separates from the limiting pin 326 of the linkage rod 323, and the linkage rod 323, under the action of the torsion spring, rotates... Figure 4 The lever oscillates counterclockwise as shown until the linkage pin 325 at the lower end of the linkage rod 323 is engaged in the first linkage groove 313 on the first swing arm 311 and the second linkage groove 334 on the second swing arm 331.

[0104] Furthermore, such as Figure 6 and Figure 7 As shown, the operator pulls the handle body 100, causing the handle body 100 to rotate around the mounting axis 20 in a direction away from the door (i.e., Figure 7 (Continuing to rotate clockwise) the handle body 100 protrusion 110 acts on the second swing arm 331 through the driven groove 335, and the second swing arm 331 rotates... Figure 6 The first swing arm 311 moves clockwise and acts on the linkage pin 325 through the second linkage groove 334. The linkage pin 325 then acts on the first swing arm 311 through the first linkage groove 313, causing the first swing arm 311 to move clockwise. Figure 6 The clockwise direction of the middle swings together with the second swing arm 331, thereby pulling the unlocking cable to unlock.

[0105] Of course, such as Figure 8 and Figure 9 As shown, if the handle body 100 is forcibly pulled open to the unfolded state by external force, when the operator pulls the handle body 100, since the transmission rod 223 is in the non-drive position, the limiting pin 326 of the linkage rod 323 cooperates with the limiting wall 225 on the transmission rod 223 to make the linkage rod 323 be in the second position. The protrusion 110 of the handle body 100 pushes the second swing arm 331 along the driven groove 335. Figure 8 When the clockwise direction of the door handle swings, the first swing arm 311 will not be linked, thus preventing the unlocking cable from being pulled, thereby improving the unlocking security of the door handle device 10.

[0106] An embodiment of the present invention also discloses an automobile, including a door, wherein the door is equipped with any of the above-described door handle devices 10.
