DETAILED DESCRIPTION

[0027] The present application provides a door handle assembly and a vehicle, wherein the door handle assembly has the advantage of small layout space. The door handle assembly and the vehicle are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0028] refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the overall structure of a door handle assembly shown in an embodiment, Figure 2 is a schematic diagram of the exploded structure of a door handle assembly shown in an embodiment; Figure 3 It is a perspective structural diagram of a handle and a movable component shown in an embodiment. The embodiment of the present application provides a door handle assembly, including a base 40, a handle 10 and a movable component. Among them, the base 40 has a drive structure mounting position 41 and a moving opening 42, at least part of the handle 10 passes through the moving opening 42 and is movably arranged on the base 40, and the handle 10 has a accommodating cavity 11; the movable component includes a drive structure 20 and a transmission assembly 30, the drive structure 20 is arranged at the drive structure mounting position, the transmission assembly 30 is connected to the drive structure 20, and extends into the accommodating cavity 11 to connect to the handle 10, and the drive structure 20 is used to drive the transmission assembly 30 to drive the handle 10 to move in a direction close to or away from the base 40.

[0029] It can be seen from the above description that part of the structure of the transmission assembly 30 can be built into the accommodating cavity 11 of the handle 10, reducing the external space occupied by the transmission assembly 30, which can make the layout of the entire door handle assembly more compact and reduce the total space required. In addition, the accommodating cavity 11 also allows part of the structure of the transmission assembly 30 to be hidden inside the handle 10, making the appearance of the door handle assembly more concise and beautiful, and also helps to reduce the impact of external factors on the transmission assembly 30 and improve the durability of the transmission assembly 30.

[0030] It should be noted that the direction in which the handle 10 is away from the base 40 can be referred to Figure 1 The Y1 direction shown, the direction in which the handle 10 is close to the base 40 can be referred to Figure 2 When the door handle assembly is installed in a vehicle, the Y1 direction is the direction away from the interior of the vehicle, and the Y2 direction is the direction close to the interior of the vehicle. When the door handle assembly is applied to a vehicle, the handle 10 moves in the Y1 direction, which means that the handle 10 pops out to allow the user to pull the door, and the handle 10 moves in the Y2 direction, which means that the handle 10 retracts to be flush with the door of the vehicle.

[0031] In one embodiment, the drive structure installation position 41 is located outside the visible range of the moving opening 42, and the base 40 blocks the drive structure 20. In this way, the base 40 can cover the drive structure 20 so that the drive structure 20 will not be exposed. That is, it is difficult for the user to directly see the drive structure 20 through the moving opening 42, which improves the aesthetics of the entire door handle assembly. The outside of the visible range here means "the drive structure installation position 41 cannot be directly observed through the moving opening 42 when viewed from the direction from the handle 10 to the base 40".

[0032] Furthermore, the handle 10 shields the transmission assembly 30 at the moving opening 42. Similarly, the handle 10 can cover the transmission assembly 30 so that the transmission assembly 30 will not leak out, further improving the aesthetics of the entire door handle assembly.

[0033] like Figure 1 In the illustrated embodiment, the drive structure installation position 41 is adjacent to the moving opening 42, and the drive structure installation position 41 is a plane structure, and the extension direction of the plane is parallel to the movable direction of the handle 10. The drive structure 20 can be placed on the plane and fixed to the base 40 by bolts, bonding, or the like.

[0034] refer to Figure 3 and Figure 4 , Figure 3: is a partial structural diagram of a handle and a movable component shown in an embodiment; in some embodiments, the driving structure 20 may include a motor 21 and a reduction box 22, the reduction box 22 is connected to the motor 21, and is used to reduce the output speed of the motor 21 and increase the output torque of the motor 21. The reduction box 22 leads to an output shaft 23, and the output shaft 23 is connected to the transmission assembly 30. Among them, the motor 21 may include but is not limited to a DC motor 21, a stepper motor 21, a servo motor 21, etc., and the reduction box 22 may include but is not limited to a planetary gear reduction box 22, a helical gear reduction box 22, a bevel gear reduction box 22, etc. Of course, in some other embodiments, the driving structure 20 may also be a pneumatic structure, a hydraulic structure, etc.

[0035] Further, in one embodiment, the transmission assembly 30 includes a worm 31, a worm wheel 32 and a screw assembly, wherein the worm 31 is connected to the output shaft 23, the worm wheel 32 is meshed with the worm 31, the screw assembly includes a screw 33 and a wire drum 34, the wire drum 34 is sleeved on the screw 33 and is threadedly connected with the screw 33, the screw 33 is meshed with the worm wheel 32, and the wire drum 34 is fixedly connected with the handle 10. The length direction of the worm 31 is perpendicular to the length direction of the screw 33, the length direction of the screw 33 is parallel to the movable direction of the handle 10, and at least part of the structure of the screw 33 is arranged in the accommodating cavity 11.

[0036] After being arranged in this way, when the output shaft 23 rotates, the worm 31 rotates, driving the worm wheel 32 to rotate. When the worm wheel 32 is connected to the screw 33, and the wire drum 34 is connected to the handle 10, the worm wheel 32 can drive the screw 33 to rotate, and at this time the wire drum 34 can move along the length direction of the screw 33, thereby driving the handle 10 to move. The transmission assembly 30 in this embodiment has a simple structure, compact matching, and occupies a small space, and at least part of the structure of the screw 33 is arranged in the accommodating chamber 11, which further saves space. In addition, this solution enables the handle 10 to move directly along the length direction of the screw 33 through the matching form of the worm wheel 32, the worm 31 and the screw assembly. When the handle 10 moves the same distance, compared with the swing form of the four-bar structure, this embodiment can obviously save space in the Y1 and Y2 directions.

[0037] In some other embodiments, the transmission assembly 30 may also be in the form of a chain drive, a belt drive, etc.

[0038] In one embodiment, the accommodating chamber 11 further includes an opening 12 facing the driving structure 20, and the worm wheel 32 and the worm 31 are connected and matched at the opening 12. Designing the connection between the worm wheel 32 and the worm 31 at the opening 12 of the accommodating chamber 11 can make full use of the space, making the arrangement of the entire transmission assembly 30 more compact.

[0039] like Figure 4In the illustrated embodiment, the opening 12 includes a first opening 121 and a second opening 122 adjacent to each other, the worm wheel 32 and the worm 31 are connected and matched at the first opening 121, and the second opening 122 faces the output shaft 23 and is recessed into the accommodating cavity 11. After such arrangement, the second opening 122 provides a space for the output shaft 23 to enter the first opening 121, so that the worm 31 on the output shaft 23 can mesh with the worm wheel 32 at the first opening 121. At the same time, the recessed design of the second opening 122 can also save space, making the structural arrangement of the transmission assembly 30 more compact.

[0040] In one embodiment, the door handle assembly further includes a touch module disposed on the handle 10, the touch module is used to generate an unlock signal according to a touch signal, and the unlock signal is used to unlock the door of the vehicle. Specifically, when the door handle assembly is applied to a vehicle, after the handle 10 pops out, the user can touch the touch module on the handle 10, and the touch module generates an unlock signal according to the user's touch signal. The touch module is used to connect to the control module of the vehicle to send the unlock signal to the control module, and the control module controls the drive device to open the door lock of the vehicle door according to the received unlock signal. Among them, the touch module can be disposed on the inner wall of the handle body 10a, and the touch module can be a capacitive touch sensor, a resistive touch sensor, etc., but is not limited thereto.

[0041] In one embodiment, the handle 10 further includes a handle body 10a and a first connecting portion 10b connected to the handle body 10a, the first connecting portion 10b protrudes from a part of the handle body 10a, the first connecting portion 10b includes a receiving cavity 11, and the first connecting portion 10b passes through the moving opening 42 and is movably arranged on the base 40. That is to say, in this solution, the receiving cavity 11 is arranged in the partially protruding first connecting portion 10b, rather than widening the entire handle 10. On the one hand, this can reduce the amount of material used in the handle 10, which is conducive to cost saving. On the other hand, under the premise of satisfying the movably connected handle 10 and base 40, this solution also provides a receiving cavity 11 for accommodating and connecting the transmission assembly 30, thereby improving the integration of the handle 10 and helping to save space.

[0042] like Figure 3 and Figure 4In the illustrated embodiment, the handle body 10a is configured as a strip structure, and the handle body 10a is provided with a first connection portion 10b at one end along the length direction thereof, and a second connection portion 10c at the other end thereof, and the second connection portion 10c protrudes from the end of the handle body 10a, and is located on the same side of the handle body 10a as the first connection portion 10b; wherein the first connection portion 10b and the second connection portion 10c are both movably disposed on the base 40. In this way, the first connection portion 10b and the second connection portion 10c are respectively located at the two ends of the handle body 10a, so that the handle 10 is more stable when moving away from or close to the base 40. At the same time, when the user pulls the handle body 10a, the first connection portion 10b and the second connection portion 10c can share the force on the handle body 10a, so as to avoid excessive force on a single connection portion.

[0043] Among them, the first connecting part 10b and the second connecting part 10c can be integrally formed, the handle body 10a is the front cover of the handle 10, the first connecting part 10b and the second connecting part 10c are the back shells of the handle 10, and a pull groove is formed between the first connecting part 10b and the second connecting part 10c, and the pull groove is recessed toward the side close to the handle body 10a to facilitate the user to pull the handle 10.

[0044] In one embodiment, at least one of the first connection part 10b and the second connection part 10c includes a sliding part, and the base 40 also includes a slide rail corresponding to the sliding part, the extension direction of the slide rail points to the handle body 10a, and the sliding part is slidably connected to the slide rail. Compared with rolling cooperation, the structure of sliding cooperation is relatively simple, and the slide rail can play a guiding role, which helps the handle to maintain a more accurate trajectory during the sliding process, and facilitates the handle 10 to move away from the base 40 or close to the base 40. In a specific embodiment, the slide rail can be a slide groove, the extension direction of the slide groove points to the handle body 10a, and the sliding part is slidably connected to the slide groove. Preferably, the first connection part 10b and the second connection part 10c can both be provided with a sliding part, and the two sliding parts can be respectively arranged on the outer walls of the first connection part 10b and the second connection part 10c, and the base 40 includes two slide rails, and the two slide rails correspond to the two sliding parts one by one. The sliding part can be a slider, a slide convex, a slide plate, etc., which can be adapted to the shape of the slide rail.

[0045] In one embodiment, a limiting structure is further provided at one end of the slide groove near the handle body 10a, and when the handle 10 moves along the slide groove away from the base 40, the limiting structure is used to cooperate with the sliding part to prevent the handle 10 from leaving the slide groove. The limiting structure includes but is not limited to a limiting plate and a limiting rib.
