[0036] The embodiments described in this specification will now be described in detail.

[0037] like Figure 1 and Figure 2As shown, this application provides a door handle assembly for use in a vehicle, including a housing 10, a door handle 20 assembled to the housing 10, a drive assembly 30, a control device 40, and a detection device 50. The drive assembly 30 is assembled to the door handle 20. The drive assembly 30, the detection device 50, and the control device 40 are electrically connected. When the detection device 50 detects a user approaching the vehicle, the control device 40 controls the drive assembly 30 to rotate the door handle 20, turning it in a direction suitable for user operation.

[0038] On the one hand, when a user approaches the vehicle from different sides, the door handle 20 can be turned to the direction the user came from, providing a better door opening experience. On the other hand, when the door opening space is narrow, the door handle 20 can also be turned to a position that facilitates opening the door.

[0039] like Figure 3 and Figure 4 As shown, the housing 10 is provided with a rotating opening 11, a sliding groove 12, and a reinforcing plate 13. The housing 10 is square. The door handle 20 is located near the rotating opening 11. When the door handle 20 is rotated, one of its two ends can pass through the rotating opening 11 for user operation.

[0040] The slide rail 12 includes a first slide rail 121 and a second slide rail 122. The first slide rail 121 is located on the top wall of the housing 10. The second slide rail 122 is located on the bottom wall of the housing 10. Each slide rail 12 extends to both sides, including a first section 123 extending to one side and a second section 124 extending to the other side. Because the slide rails 12 extend to both sides, when the door handle 20 is installed facing both sides, the user can pull the door handle to open the vehicle door.

[0041] The reinforcing plate 13 is fixed inside the housing 10, and can be integrally formed with the housing 10 or separately formed from the housing 10. A third sliding groove 131 is provided on the reinforcing plate 13.

[0042] like Figure 3 and Figure 4 As shown, the door handle 20 includes a main body 21 and a rotating part 22. The main body 21 is rectangular in shape. The rotating part 22 protrudes from the main body 21. The rotating part 22 can protrude from the side of the main body 21 facing the housing 10, making the outward-facing side of the main body 21 relatively flat, so that the door handle 20 can be approximately flush with the rotating opening 11, completely concealing the door handle 20. The rotating part 22 can also protrude from the side of the main body 21 away from the housing 10, or it can protrude from both sides of the main body 21.

[0043] A connecting hole 23 is provided on the rotating part 22. In this embodiment, the rotating part 22 is a semi-cylinder. The connecting hole 23 is located at the bottom of the rotating part 22. The connecting hole 23 extends from the bottom of the rotating part 22 to the top of the rotating part 22. The door handle 20 can rotate around the axis of the rotating part 22. In other embodiments, the rotating part 22 can be of any shape, such as a cylinder or a square prism. The arrangement of the connecting hole 23 is not limited, and it can also be located at the top or middle of the rotating part 22. The structural form of the connecting hole 23 is not limited, and it can be a through hole or a blind hole.

[0044] like Figure 5 As shown, a locking cable 24 is provided on the side of the door handle 20 facing inwards from the housing 10. The locking cable 24 is used to connect to the vehicle's locking structure. The door opening method is simple in structure and easy to manufacture, while effectively avoiding interference with the rotation of the door handle 20. In this embodiment, the locking cable 24 is connected to the rotating part 22. Since the door handle 20 rotates around the axis of the rotating part 22, connecting the locking cable to the rotating part 22 reduces the positional variation of the locking cable 24, making the internal structure more stable. In other embodiments, the locking cable 24 can be connected to any position on the main body 21 or the door handle 20.

[0045] The door handle 20 is provided with a sliding door surface 25 facing the housing 10. When the door handle 20 is turned to either side, the user can place his / her fingers on the sliding door surface 25 and pull the door handle 20 to open the car door.

[0046] The drive component 30 can be a motor or any device that provides a rotational power source. For example... Figure 3 As shown, the drive assembly 30 includes a drive shaft 31. The drive shaft 31 is assembled into the connecting hole 23. The drive shaft 31 and the connecting hole 23 are interference-fitted. The rotation of the drive shaft 31, through the frictional force of the interference fit, drives the door handle 20 to rotate. The door handle is directly driven by a motor, which is simple in structure and easy to implement.

[0047] like Figure 6 As shown, in some embodiments, the door handle assembly further includes a transmission mechanism 60. The transmission mechanism 60 is disposed between the door handle 20 and the drive assembly 30. The power of the drive assembly 30 is transmitted to the door handle 20 through the transmission mechanism 60. The transmission mechanism 60 can increase the torque transmitted from the drive assembly 30 to the door handle 20, reduce the load on the drive assembly 30 itself, and extend the service life of the drive assembly 30.

[0048] In one embodiment, the transmission mechanism 60 is a worm gear mechanism. The transmission mechanism 60 includes a worm wheel 61 and a worm 62. The worm wheel 61 is assembled to the door handle 20. The worm is assembled to the drive assembly 30. Besides increasing torque, the worm gear mechanism also has a one-way self-locking function. When the user pulls the door handle 20, the worm wheel 61 cannot rotate the worm 62, and the door handle 20 itself will not rotate, effectively ensuring a good user experience and preventing damage to the drive assembly 30 due to forced rotation. In other embodiments, the transmission mechanism 60 may be a gear set, a rack and pinion mechanism, or a threaded transmission mechanism, etc.

[0049] like Figure 3 and Figure 4 As shown, the door handle assembly also includes a roller 70. The roller 70 is assembled into the slide groove 12. The roller 70 can move within the slide groove to meet the user's need to pull the door handle 20. At the same time, the roller 70 can support the door handle 20 and the drive assembly 30. The roller 70 can be a concave structure that is wide on both sides and narrow in the middle. The roller 70 can also be a structure that is narrow on both sides and wide in the middle. The roller 70 can also be cylindrical, with the width of the sides and the middle being the same. The shape of the slide groove 12 is adapted to the shape of the roller 70.

[0050] The roller 70 includes a first roller 71, a second roller 72, and a third roller 73. The first roller 71 is disposed on the door handle 20. The second roller 72 is disposed on the drive assembly 30. The first roller 71 is assembled to a first slide groove 121. The second roller 72 is assembled to a second slide groove 122. The first roller 71 is located at the top of the door handle 20. The second roller 72 is located at the bottom of the drive assembly 30. The door handle 20 and the drive assembly 30 are assembled as a single unit, with the first roller 71 and the second roller 72 located at opposite ends of this unit, effectively securing the door handle 20 and the drive assembly 30.

[0051] The third roller 73 can be assembled to the door handle 20 or the drive assembly 30. The third roller 73 is assembled to the third slide groove 131. The first roller 71, the second roller 72, and the third roller 73 are arranged coaxially. This increases the installation strength of the door handle 20 and the drive assembly 30. In other embodiments, the number of rollers 70 can be greater, and the specific number and installation position are not limited, further improving the installation strength of the door handle 20 and the drive assembly 30.

[0052] like Figure 5 As shown, the door handle assembly also includes a wiring harness pre-installed box 80. This box houses the wiring harness connected to the control device 40. The wiring harness pre-installed box 80 includes an internal elastic member 81 to which the wiring harness is wound. When the user pulls the door handle 20, the wiring harness extends. When the door handle 20 is turned back, the wiring harness automatically retracts into the wiring harness pre-installed box 80 under the action of the elastic member 81.

[0053] like Figure 2 and Figure 5 As shown, the door handle assembly also includes an identification device 90 for detecting user identity. The identification device 90 is electrically connected to the control device 40. The control device 40 uses the user identity information transmitted by the identification device 90 to control the locking of the vehicle. When the user's identity is confirmed as the vehicle owner, the control device 40 controls the vehicle's locking structure to open, at which point the user can open the door by moving the door handle 20.

[0054] The identification device 90 includes a fingerprint recognition module 91 for detecting the user's fingerprint as user identification information. Fingerprint recognition for user identification is fast and convenient. The fingerprint recognition module 91 is located on the left and right sides of the sliding door surface 25. When the door handle 20 is turned to either side, the user can unlock the vehicle using the fingerprint recognition module 91.

[0055] This application also provides a vehicle, including a vehicle pillar and a door. The vehicle also includes the aforementioned door handle assembly disposed on the door. Figure 7 As shown, the detection device 50 is installed on the vehicle body or door. The door handle of this vehicle can be rotated to a direction suitable for user operation, including the user's direction of approach and a suitable opening direction in confined door spaces, providing the user with a better operating experience. The vehicle in this application can be an electric vehicle, a gasoline vehicle, or a hybrid vehicle, etc.

[0056] The detection device 50 includes a radar 51 and / or a camera 52 for detecting the direction in which a user approaches. The radar 51 uses electromagnetic waves to detect the direction of a user approaching from a relatively far distance. Simultaneously, the radar 51 performs detection both day and night. By incorporating the camera 52, it enables person recognition and accurate detection of the user's approach direction. During operation, the radar 51 first roughly determines which side of the vehicle the user is approaching from. Once the approximate approach direction is determined, the camera 52 then begins to accurately determine the user's approach direction.

[0057] There can be multiple radars 51 or cameras 52. They can be installed on the roof, front, rear, or body of the vehicle. Specifically, radars 51 or cameras 52 can be installed on the vehicle's roof, headlights, taillights, A-pillars, B-pillars, C-pillars, etc.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application.
