Description

[0001] This application claims priority to Chinese patent application No. 202410316924.6, filed on March 19, 2024, and entitled “Vehicle and Hidden Door Handle Thereof,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to a vehicle, and in particular to a vehicle with a projection device. Background Art

[0003] Vehicles use projection devices to project images on the ground near the vehicle. In the prior art, patent document US20200377004A1 discloses installing a projection device below a conventional vehicle door handle to project an image on the ground near the vehicle. Furthermore, patent document CN117043011A discloses installing a projection unit on a vehicle's rearview mirror. The projection unit can pivot or flip between at least two positions based on the brightness value of the surrounding environment detected by a brightness sensor to project images of different areas on the ground near the vehicle. Summary of the Invention

[0004] After in-depth research, the inventors of the present application found that the traditional door handle in patent document US20200377004A1 is fixedly mounted to the vehicle door, so that the area, area and size of the image projected by the projection device installed under the traditional door handle on the ground near the vehicle are relatively fixed, and dynamic projection display cannot be achieved. In addition, when the vehicle user grasps the door handle to open the door, he will touch or grasp the projection device under the door handle, thereby reducing the user's experience, and multiple touches or grasping can easily cause damage to the projection device or loose installation. The installation of the projection device under the traditional door handle also reduces the aesthetics of the vehicle. Furthermore, since the projection device is installed under the traditional door handle and is exposed to the outside of the vehicle, it is easily damaged by dust, rain, light, etc.

[0005] After in-depth research, the inventors of this application also discovered that the projection unit in patent document CN117043011A is installed on the vehicle's rearview mirror, so that the projection unit is located near the front of the vehicle and at a relatively high position. As a result, the projection unit can only project images on the ground over a portion of the vehicle's length, and the clarity of the image projected on the ground near the vehicle is reduced. Mounting the projection unit on the rearview mirror reduces the vehicle's aesthetics. Because the projection unit is mounted on the rearview mirror, it is exposed to the outside of the vehicle and is susceptible to damage from dust, rain, light, and the like. Furthermore, the projection unit projects different images on the ground near the vehicle depending on the brightness of the surrounding environment, failing to achieve a wider range of interactions between the vehicle and other vehicles, pedestrians, etc., and a wider range of experiences for vehicle users. Furthermore, the projection unit only pivots or flips, making it impossible to project images of a wider variety of shapes to accommodate multiple projection modes.

[0006] In order to solve the above technical problems, the present application provides, in a first aspect, a door handle system, comprising a handle, a handle driving device, and a projection device. The handle driving device is configured to drive the handle to expand or retract relative to the vehicle door. The projection device is disposed within the handle. The projection device has a blocking position and one or more projection positions. The projection device is configured to move from the blocking position to the one or more projection positions as the handle expands relative to the vehicle door, so that the projection device projects an image onto a projection surface.

[0007] According to some specific embodiments, the door handle system further includes a projection driving device connected to the projection device and configured to drive the projection device to move relative to the handle.

[0008] According to some specific embodiments, the projection device moves relative to the handle to project an image of a predetermined shape and area on a predetermined projection area of ​​the projection surface.

[0009] According to some specific embodiments, the projection driving device drives the projection device to rotate relative to the handle. The projection device rotates independently around a first rotation axis and a second rotation axis.

[0010] According to some embodiments, the handle is extended or retracted relative to the vehicle door along a plane, and the first rotation axis and the second rotation axis are parallel to the plane. The first rotation axis is perpendicular to the second rotation axis.

[0011] According to some specific embodiments, the projection device and the projection driving device are arranged separately from the gripping portion of the handle in the longitudinal direction of the handle.

[0012] According to some specific embodiments, the projection drive device includes a first projection motor and a second projection motor. The first projection motor is configured to drive the projection device to rotate around the first rotation axis. The second projection motor is configured to drive the projection device to rotate around the second rotation axis.

[0013] According to certain specific embodiments, the projection drive device is mounted to the handle via a bracket. The bracket includes a main body, the main body including a side surface, and the side surface is mounted to the handle. The main body also includes a first arm and a second arm disposed opposite the side surface. The first projection motor is mounted to the first arm, and the second projection motor is mounted to the second arm.

[0014] According to some specific embodiments, a first output shaft of the first projection motor is connected to the projection device via a first connecting member and a second connecting member. Rotation of the first output shaft drives rotation of the first and second connecting members, thereby driving the projection device to rotate about the first rotation axis. A second output shaft of the second projection motor is connected to the projection device via a third connecting member. Rotation of the second output shaft drives rotation of the third connecting member, thereby driving the projection device to rotate about the second rotation axis.

[0015] According to some specific embodiments, the door handle system further includes a control device configured to: control the handle driving device to operate to extend or retract the handle, control the projection driving device to operate to move the projection device, and control the projection device to operate to project the image.

[0016] According to some specific embodiments, control of the deployment opening of the handle relative to the vehicle door, the operation mode of the projection driving device, and the movement of the projection device relative to the handle is determined based on an operating state of the vehicle.

[0017] According to some specific embodiments, the projection device includes a first projection head. In a first projection mode, while the control device controls the handle driving device to drive the handle to unfold, the control device controls the first projection head of the corresponding projection device mounted on the handle to activate and project an image having a pattern, such that the projected image gradually appears as the handle gradually unfolds.

[0018] According to some specific embodiments, the projection device includes a second projection head. In the second projection mode, the control device controls the handle driving device to drive the handle to unfold, and controls the second projection head of the corresponding projection device mounted on the handle to start and project an image of a predetermined color for a predetermined duration.

[0019] According to certain specific embodiments, the projection device includes a third projection head. In a third projection mode, for each handle on one side of the vehicle's two doors and the corresponding first projection motor, second projection motor, and projection device mounted to each handle, the control device controls the handle drive device to deploy the handle to a predetermined deployment angle, controls the operation of the corresponding first projection motor to drive the corresponding projection device to rotate about the first rotation axis by a first angle, controls the operation of the corresponding second projection motor to drive the corresponding projection device to rotate about the second rotation axis by a second angle, and controls the third projection head in the corresponding projection device to activate and project an image of a predetermined color. The images projected by the corresponding third projection heads on the respective handles are spliced ​​to form a combined image.

[0020] According to certain specific embodiments, the third projection mode is a turning mode, and control of the unfolding opening of the handle relative to the vehicle door and the first rotation angle of the projection device around the first rotation axis and the second rotation angle around the second rotation axis is determined based on the vehicle's turning angle signal and vehicle speed signal.

[0021] According to some embodiments, the control device is a single controller.

[0022] In a second aspect, the present application provides a vehicle comprising the door handle system according to any one of the above-mentioned first aspects.

[0023] Compared with the prior art, the vehicle and door handle system provided by this application have at least the following beneficial technical effects:

[0024] In the first aspect, the projection device is mounted to the handle so that as the opening of the handle relative to the vehicle door changes, the size of the portion of the projection device blocked by the vehicle door changes accordingly and a corresponding indication image is dynamically projected on the projection surface (e.g., the ground near the vehicle), thereby being suitable for more projection modes.

[0025] Secondly, the projection device is mounted to the handle so that it retracts into the vehicle door as the handle retracts, thereby preserving the vehicle's aesthetics. Furthermore, the projection device is only exposed to the vehicle exterior when in use, remaining concealed within the vehicle door most of the time. Therefore, the projection device is less susceptible to damage or instability due to external environmental factors (e.g., dust, rain, sunlight, etc.) or external forces (e.g., unintentional contact by the user or other personnel).

[0026] In a third aspect, the projection device is arranged separately from the grip portion of the handle in the longitudinal direction of the handle to prevent the vehicle user from touching the projection device when gripping the handle, thereby not affecting the user experience and reducing the possibility of damage to the projection device.

[0027] In the fourth aspect, the combination of the unfolding of the handle and the movement of the projection device enables the projection device to project images of a wider variety of areas and shapes in more projection areas, thereby implementing a wider variety of projection modes. Furthermore, the projection device unfolds accordingly as the handle unfolds relative to the vehicle door, providing a motion dimension for the projection device. The projection drive device drives the projection device to move, providing another motion dimension for the projection device. This application utilizes the motion dimension of the vehicle's original handle as a motion dimension for the projection device, thereby reducing the motion dimension that the projection drive device needs to configure for the projection device, simplifying the structure of the projection drive device, and thereby simplifying the structure of the vehicle and its door handle system, and reducing the cost of improvement.

[0028] In the fifth aspect, the deployment degree of the handle and the movement position of the projection device are controlled based on the operating status of the vehicle, so that the projection device can project the required image in more projection modes, realize more interactions between the vehicle and other vehicles, pedestrians, etc., and more experiences for vehicle users.

[0029] Other objects and advantages of the present application will become apparent from the following description of the present application with reference to the accompanying drawings, which will help to provide a comprehensive understanding of the present application.

[0069] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although directional terms such as "front," "back," "up," "down," "left," "right," "top," and "bottom" are used in this application to describe various example structural parts and elements of the present application, these terms are used herein for convenience of description only and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be arranged in different orientations, these directional terms are only for illustration and should not be considered as limiting.

[0070] Ordinal numbers such as "first" and "second" used in this application are only used for distinction and identification and do not have any other meanings. Unless otherwise specified, they do not indicate a specific order and do not have a specific association.

[0071] Figure 1 A schematic structural diagram of the vehicle 100 and its components and projection areas of the present application is shown to illustrate the positional relationship between the vehicle 100 and its components and projection areas.

[0072] like Figure 1 As shown, a vehicle 100 is provided with two handles 101 on each of its side doors 102. The handles 101 are concealed handles that can be driven by a handle drive (not shown), such as a motor, to extend or retract relative to the vehicle door 102. When the handles 101 are extended relative to the vehicle door 102 by the drive, a vehicle user can grasp the handles 101 to open the vehicle door 102. After the vehicle door 102 is opened, the vehicle user releases the handles 101, and the handles 101 are driven by the drive to retract relative to the vehicle door 102. When the handles 101 are retracted, the outer surface of the handles 101 is flush with the outer surface of the vehicle door 102.

[0073] The projection device 210 is provided in the handle 101. The projection device 210 has a blocking position and one or more projection positions. At the blocking position, the projection device 210 is completely blocked by the vehicle door 102. At one or more projection positions, the projection device 210 is partially blocked by the vehicle door 102 or is not blocked by the vehicle door 102. The projection device 210 is configured to move from the blocking position to one or more projection positions as the handle 101 is unfolded relative to the vehicle door 102, so that the projection device 210 projects an image onto a projection surface. The projection device 210 is accordingly unfolded or retracted relative to the vehicle door 102 as the handle 101 is unfolded or retracted. The projection device 210 is installed to face a projection surface, such as the ground near the vehicle or other suitable surface on which an image needs to be projected, so that an image can be projected onto the projection surface. In order to clearly illustrate the handle 101, Figure 1 Each of the four handles 101 in the vehicle door 102 extends from an opening in the vehicle door 102, meaning that the handle 101 is in an extended state. At this time, the projection device 210 on the handle 101 is also extended (i.e., extended). For example, the projection device 210 is not blocked by the vehicle door 102 or is partially blocked by the vehicle door 102. Thus, the projection device 210 can project an image on the projection area 103 of the projection surface to provide corresponding instructions to users, other vehicles, pedestrians, etc. The degree of opening of the handle 101 relative to the vehicle door 102 is adjustable so that the size of the portion of the projection device 210 blocked by the vehicle door 102 is adjustable. When the handle 101 is extended to one degree of opening, the projection device 210 is partially blocked by the vehicle door 102. When the handle 101 is extended to another degree of opening, the projection device 210 is not blocked by the vehicle door 102. The size of the portion of the projection device 210 blocked by the vehicle door 102 varies based on the change in the degree of opening of the handle 101.

[0074] Projection area 103 is located on the ground near both sides of vehicle 100 and spans substantially the entire length of vehicle 100. The projection area 103 on the left side of vehicle 100 is the combined projection area of ​​the projection devices 210 on the two handles 101 on the left side of vehicle 100, while the projection area 103 on the right side of vehicle 100 is the combined projection area of ​​the projection devices 210 on the two handles 101 on the right side of vehicle 100. The projected images of the projection devices 210 on the two handles 101 on the side of vehicle door 102 can be spliced ​​together to form a longer projection image.

[0075] The projection device 210 can be driven by a projection drive device to move relative to the handle 101, such as by rotation. The movement of the projection device 210 can change the shape, size, and / or projection area 103 of the image projected by the projection device 210 on the projection surface. The position of the projection device 210 relative to the handle 101 after movement, combined with the degree of opening of the handle 101 relative to the vehicle door 102, enables the projection device 210 to project a wider variety of images on the projection surface, such as those with different shapes, sizes, and / or projection areas. This allows for more customized projection modes, enabling a wider range of interactions between the vehicle 100 and other vehicles, pedestrians, and the like, and providing a wider range of experiences for vehicle users.

[0076] Figure 2A yes Figure 1 The handle 101 is mounted on the base 201 in the vehicle door. Figure 2B yes Figure 2A The handle 101 is shown in a front view in a partially unfolded state. Figure 2C yes Figure 2A The handle 101 is shown in a front view in a fully unfolded state, so as to illustrate the positional relationship and the matching relationship between the handle 101 and other components. Figure 2A The partially enlarged view shows the projection device 210 and the projection driving device 603 installed in the handle 101.

[0077] like Figure 2A As shown, a handle 101 is mounted on a base 201 mounted in a vehicle door. The base 201 includes a housing 205. In one embodiment, the base 201 is mounted to the vehicle door via a flange 203 on the housing 205, thereby attaching the handle 101 to the vehicle door. The handle 101 is movable relative to the base 201 to expand or retract, thereby expanding or retracting relative to the vehicle door. The housing 205 of the base 201 defines an opening 202. The handle 101 can be moved into and out of the opening 202 of the base 201 to expand or retract relative to the base 201.

[0078] When the handle 101 is retracted relative to the base 201, the outer surface of the handle 101 is flush with the outer surface of the vehicle door to which the base 201 is mounted. In one embodiment, the plane of the outer edge 206 of the flange 203 of the base 201, which faces the handle 101, is flush with the outer surface of the vehicle door. When the handle 101 is retracted relative to the base 201, the outer surface of the handle 101 is flush with the plane of the outer edge 206 of the base 201, thereby being flush with the outer surface of the vehicle door. A projection device 210 is mounted in the handle 101. When the handle 101 is moved out of the opening 202 of the base 201, the projection device 210 can be correspondingly moved out without being blocked or partially blocked by the side wall 204 of the housing 205 of the base 201, thereby enabling the projection of a corresponding image on the projection surface. The projection device 210 faces the side wall 204. When the projection device 210 is blocked by the side wall 204 of the base 201 , the projection device 210 is correspondingly blocked by the vehicle door.

[0079] The projection device 210 is equipped with a projection driving device 603. The projection driving device 603 drives the projection device 210 to move so as to change the shape, area and / or projection region of the image projected by the projection device 210 on the projection surface. Figure 2A The projection drive device 603 shown in FIG. 1 drives the projection device 210 to rotate about a first rotation axis Y and a second rotation axis X. The projection device 210 rotates about the first rotation axis Y and the second rotation axis X independently of each other. The first rotation axis Y and the second rotation axis X are different. The handle 101 moves along a plane P into or out of the opening 202 of the base 201 to expand or retract relative to the vehicle door. The first rotation axis Y and the second rotation axis X are parallel to the plane P. The first rotation axis Y is perpendicular to the second rotation axis X. In other embodiments, the projection drive device 603 includes other suitable drive devices or structures to drive the projection device 210 to perform the above-described functions.

[0080] The handle 101 includes a grip portion 207. When the handle 101 is extended, the vehicle user can grasp the grip portion 207 to open the vehicle door. A projection mounting portion 208 is provided on the handle 101. The projection mounting portion 208 is recessed inward from the surface of the handle 101 facing the vehicle bottom to accommodate the projection device 210 and the projection drive device 603. The projection device 210 and the projection drive device 603 are mounted in the projection mounting portion 208 so that when the handle 101 is extended or retracted relative to the base 201, they extend or retract accordingly without contacting the base 201. This prevents damage or loosening of the mounting due to contact, and prevents the movement of the handle 101 from being affected. The projection mounting portion 208 includes a projection mounting surface 220. The projection device 210 and the projection drive device 603 can be mounted to the projection mounting surface 220 via a bracket 320. The projection mounting surface 220 is flat.

[0081] In the longitudinal direction L (lengthwise extension direction) of the handle 101 ( Figure 2A The projection mounting portion 208 is arranged separately from the grip portion 207 (in the generally vertical direction shown in FIG). The projection device 210 and projection drive device 603 mounted in the projection mounting portion 208 are correspondingly arranged separately from the grip portion 207 to prevent vehicle users from touching the projection device 210 and projection drive device 603 when gripping the grip portion 207 of the handle 101. This prevents the user from touching the projection device 210 and projection drive device 603, thereby minimizing user experience and preventing damage or insecure installation of the projection device 210 and projection drive device 603 due to contact, thereby improving the stability of the door handle system. The grip portion 207 is located in the middle of the handle 101, while the projection mounting portion 208 is located at the end of the handle 101.

[0082] Figures 2B-2C In one embodiment, the handle 101 is shown to translate along a plane P relative to the opening 202 of the base 201 to expand or retract relative to the base 201. Figure 2B As shown, the handle 101 is moved outward from the opening 202 by a first distance so that the handle 101 is in a partially unfolded state relative to the base 201. At this time, the projection device 210 is partially blocked by the side wall 204 of the housing 205 of the base 201. Figure 2C As shown, the handle 101 is moved outward from the opening 202 by a second distance greater than the first distance so that the handle 101 is in a fully extended state relative to the base 201, and at this time, the projection device 210 is not blocked by the side wall 204 of the base 201. When the handle 101 is not moved outward from the opening 202 (i.e., retracted into the base 201) so that the handle 101 is in a retracted state relative to the base 201, the projection device 210 is completely blocked by the side wall 204 of the base 201.

[0083] In another embodiment, the handle 101 pivots along plane P in the opening of the base about a pivot axis to expand or retract relative to the base. A projection mounting portion is provided at one end of the handle 101, distal from the pivot axis, for accommodating and mounting the projection device 210 and the projection drive device 603. As the handle 101 pivots about the pivot axis, the projection device 210 can be moved in or out accordingly, either without being obstructed, partially obstructed, or completely obstructed. In other embodiments, the handle 101 is expanded or retracted relative to the base using other suitable structures and / or methods.

[0084] Figure 3A yes Figure 2A The diagram shows a three-dimensional structure of the projection device 210 and the projection driving device 603 installed together in the handle, viewed from a first angle, wherein the projection device 210 is in a non-rotated state, ie, an initial state. Figure 3B yes Figure 3AThe schematic diagram of the three-dimensional structure of the projection device 210 is shown in the state of being rotated 30° around the first rotation axis Y. Figure 3C yes Figure 3A FIG. 2 shows a schematic diagram of a three-dimensional structure of the projection device 210 when the projection device 210 is rotated 30° around the second rotation axis X. Figure 3D yes Figure 3A The diagram shows a three-dimensional structure of the projection device 210 in a state where both the first rotation axis Y and the second rotation axis X are rotated by 30°. Figure 3E yes Figure 3A The diagram shows a three-dimensional structure of the projection device 210 and the projection driving device 603 installed together, viewed from a second angle.

[0085] like Figures 3A-3E As shown, the projection drive device 603 is connected to the projection device 210 to drive the projection device 210 to rotate. The projection drive device 603 and the projection device 210 are mounted to the handle on the vehicle door via a bracket 320. The bracket 320 includes a main body 305, and the main body 305 includes a side surface 306. The side surface 306 is arranged to be substantially parallel to the projection image output surface of the projection device 210 and away from the projection device 210. The bracket 320 is mounted to the handle via the side surface 306 to mount the projection drive device 603 and the projection device 210 to the handle. For example, the side surface 306 of the bracket 320 can be aligned with the projection mounting surface 220 on the projection mounting portion of the handle (see FIG. 2 ). Figure 2A ) join.

[0086] The projection device 210 includes a first projection head 301, a second projection head 302, a third projection head 303, and a mounting body 304. Each of these projection heads is mounted within the mounting body 304. The projection drive device 603 includes a first projection motor 311 and a second projection motor 312. The bracket 320 also includes a first arm 321 and a second arm 322 disposed opposite the side surface 306. The bracket 320's body 305 is generally L-shaped. The first arm 321 extends from one end of the bracket 305, for example, horizontally. The second arm 322 extends from the other end of the bracket 305, for example, vertically. The first projection motor 311 is mounted to the first arm 321 of the bracket 320. The second projection motor 312 is mounted to the second arm 322 of the bracket 320. The first arm 321 and the second arm 322 are plate-shaped structures. In other embodiments, the first arm 321 and the second arm 322 may comprise other suitable structures. In other embodiments, the bracket 320 may comprise other suitable structures. In one embodiment, the bracket 320 may be part of the base 201 .

[0087] The projection drive device 603 includes a first projection motor 311 and a second projection motor 312. The first projection motor 311 drives the projection device 210 to rotate about a first rotation axis Y. The second projection motor 312 drives the projection device 210 to rotate about a second rotation axis X. The first projection motor 311 is connected to the projection device 210 via a first connector 323 and a second connector 324 to drive the projection device 210 to rotate about the first rotation axis. The first output shaft 313 of the first projection motor 311 extends from the first arm 321 of the bracket 320 and connects to one end of the first connector 323. The other end of the first connector 323 is connected to one end of the second connector 324, and the other end of the second connector 324 is connected to the mounting body 304 of the projection device 210. The first connector 323 and the second connector 324 are fixedly connected via a first coupling structure 326. The second connector 324 is fixedly connected to the mounting body 304 via a second coupling structure 327. The first projection motor 311 operates to rotate its first output shaft 313. The rotation of the first output shaft 313 drives the first connecting member 323 to rotate, thereby driving the second connecting member 324 to move, and then driving the installation body 304 to rotate around the first rotation axis Y, thereby causing the first projection head 301, the second projection head 302, and the third projection head 303 to rotate around the first rotation axis Y. Figures 3A-3D As shown, the first rotation axis Y is a vertical axis. In one embodiment, the first coupling structure 326 and the second coupling structure 327 are connecting rods. In other embodiments, the first coupling structure 326 and the second coupling structure 327 include other suitable coupling structures.

[0088] The second projection motor 312 is connected to the projection device 210 through the third connecting member 325 to drive the projection device 210 to rotate around the second rotation axis. The second output shaft 314 of the second projection motor 312 extends from the second arm 322 to be connected to the middle part of the third connecting member 325, and one end of the third connecting member 325 is connected to the installation body 304 of the projection device 210. The third connecting member 325 is fixedly connected to the installation body 304 through a third connecting structure 328. The third connecting member 325 is U-shaped. The second projection motor 312 runs to rotate its second output shaft 314, and the second output shaft 314 rotates to drive the third connecting member 325 to rotate, thereby driving the installation body 304 to rotate around the second rotation axis X, thereby causing the first projection head 301, the second projection head 302, and the third projection head 303 to rotate around the second rotation axis X. Figures 3A-3DAs shown, the second rotation axis X is a horizontal axis. In one embodiment, the third coupling structure 328 is a connecting rod. In other embodiments, the third coupling structure 328 includes other suitable coupling structures. In other embodiments, the first projection motor 311 and the second projection motor 312 are connected to the projection device 210 via other suitable structures, so that the first projection motor 311 and the second projection motor 312 can drive the projection device 210 to rotate independently about the first rotation axis Y and the second rotation axis X.

[0089] like Figure 3A As shown, the first projection motor 311 and the second projection motor 312 are not running, so that the projection device 210 is in a non-rotating state, that is, an initial state. Figure 3B As shown, the first projection motor 311 is running to drive the projection device 210 to rotate 30° around the first rotation axis Y, and the second projection motor 312 is not running so that the projection device 210 does not rotate around the second rotation axis X. Figure 3C As shown, the second projection motor 312 is running to drive the projection device 210 to rotate 30° around the second rotation axis X, and the first projection motor 311 is not running so that the projection device 210 does not rotate around the first rotation axis Y. Figure 3D As shown, the first projection motor 311 operates to drive the projection device 210 to rotate 30° around the first rotation axis Y, and the second projection motor 312 operates to drive the projection device 210 to rotate 30° around the second rotation axis X. In other embodiments, the projection device 210 may be rotated by other suitable angles around the first rotation axis Y and / or the second rotation axis X to be in a suitable position, thereby performing a suitable projection operation.

[0090] In one embodiment, the projection head in the projection device 210 includes a light source and an optical structure. Light emitted by the light source passes through the optical structure, presenting an image on the projection surface. After a pattern piece is inserted into the optical structure, the pattern can be presented on the projection surface. For example, the optical structure includes a focusing lens and an imaging lens. The pattern piece is located between the focusing lens and the imaging lens. This structure makes the structure of the projection device 210 smaller, suitable for installation on a handle, and has low cost. The projection device of the present application includes other suitable projection heads and can perform projection display through other suitable methods.

[0091] In one embodiment, one of the first projection head 301, the second projection head 302, and the third projection head 303 projects to implement a first projection mode, another projection head projects to implement a second projection mode, and the remaining projection head projects to implement a third projection mode. In one embodiment, in the first projection mode, a desired pattern piece is set in the projection head to project the desired pattern. The first projection mode includes a welcome mode. When a vehicle user approaches the vehicle with the car key, the handle can gradually unfold relative to the vehicle door so that the projection head gradually unfolds relative to the vehicle door, thereby gradually presenting a projected pattern on the projection surface (e.g., the ground near the vehicle). The projected pattern increases from small to large as the handle is unfolded. The pattern is presented in a dynamic manner, thereby enhancing the vehicle user's experience. When a different pattern needs to be projected, the pattern piece or the projection head can be replaced.

[0092] In the second projection mode, no gobo is provided. Instead, a light source emits light of different colors to project images of different colors onto the projection area. The light source includes a multi-color LED. By controlling the chip configured therein to cause the multi-color LED to emit light of the desired color for the desired duration, the projection head can project images of the desired color in the desired pattern. For example, in the vehicle's width indication mode, a yellow image is projected to help other vehicles determine the vehicle's size and width, thereby improving driving safety. In the vehicle's charging mode, a green image is projected to indicate to the vehicle user and other personnel that the vehicle is charging. In the vehicle's autonomous driving mode, a blue image is projected to indicate to other personnel or vehicles that the vehicle user has enabled the autonomous driving function, thereby enabling other personnel to drive the vehicle safely. In the vehicle's lane change mode, a breathing yellow image is projected on the side of the vehicle to be changed lanes to indicate to other personnel or vehicles that the vehicle is about to change lanes. For example, the present application controls the projection device 210 (including the projection head) on the corresponding side of the vehicle door to project the desired image based on the vehicle's turn signal (e.g., left turn signal or right turn signal).

[0093] In the third projection mode, an image of a desired size and / or shape is projected onto the desired projection area by combining the handle's unfolded position with the rotational position of projection device 210. Furthermore, the images projected by projection devices 210 (e.g., using one of the projection heads) on the front and rear doors on one side of the vehicle are spliced ​​together to project the desired image. The third projection mode includes a turning mode, which is used to indicate danger zones when the vehicle is turning to warn pedestrians and other vehicles (e.g., bicycles).

[0094] In other embodiments, the present application may implement other suitable projection modes. The present application may implement the above-mentioned projection modes by using other suitable numbers of projection heads. For example, the projection device 210 may include only one projection head or two projection heads to implement at least one of the above-mentioned first, second, and third projection modes. The present application may project images on the projection surface on both sides or one side of the vehicle as needed. The present application may use other suitable colors or presentation methods (e.g., flashing methods) to implement the above-mentioned projection modes of the vehicle.

[0095] Figures 4A-4C A schematic diagram showing an image in the first projection mode of the present application, Figure 4D Schematic diagram showing the projection area where the image is projected in the second projection mode of the present application. Figure 4A As shown, the image in the first projection mode includes a first pattern image 401. Figure 4B As shown, the image in the first projection mode includes a second pattern image 402. Figure 4C As shown, the image in the first projection mode includes the third pattern image 403. In other embodiments, the image in the first projection mode of the present application includes other appropriate pattern images.

[0096] like Figure 4D As shown, the image projected in the second projection mode is located in the projection area 404. In the second projection mode, a projection head is used, for example, a projection head in the projection device on the handle 101 of the front door, to project the image in the projection area 404. Figure 4D 4 shows a projection area 404 in the shape of a long block. In other embodiments, the present application includes projection areas of other suitable shapes.

[0097] Figure 5A A schematic diagram showing the crushing areas of the inner and outer wheels of the vehicle 100 when turning, Figure 5B yes Figure 5A FIG. 1 is a schematic diagram of an image projected by the projection device 210 when the vehicle 100 starts to turn. Figure 5C yes Figure 5A FIG. 1 shows a schematic diagram of an image projected by the projection device 210 when the vehicle 100 is halfway through a turn. Figure 5D yes Figure 5A The diagram shows an image projected by the projection device 210 when the vehicle 100 is close to completing a turn, so as to illustrate that the vehicle 100 presents a desired projection image in the turning mode.

[0098] The projection device 210 of the present application can project the required image when the vehicle 100 turns to indicate the dangerous area when the vehicle turns. The projected image can change accordingly as the angle of the vehicle 100 turns. Figure 5AAs shown, when the vehicle 100 turns from the right side to the left side, the inner wheel of the vehicle (the left wheel of the vehicle) travels in the inner wheel crushing area 501 and the outer wheel of the vehicle (the right wheel of the vehicle) travels in the outer wheel crushing area 502 .

[0099] like Figure 5B As shown, when vehicle 100 begins to turn, both the projection devices 210 on the front and rear sides of the left door project images into a combined projection area 505, i.e., a large triangular area. For example, combined projection area 505 displays a red color. Combined projection area 505 includes a front projection area 503 projected by the projection device 210 on the front side of the left door and a rear projection area 504 projected by the projection device 210 on the rear side of the left door. Front projection area 503 is roughly trapezoidal, while rear projection area 504 is roughly triangular. Front projection area 503 and rear projection area 504 are combined to form combined projection area 505. In one embodiment, the handle on the left door can be unfolded to a desired degree so that the projection device 210 mounted thereon is obscured by the door. The front and rear projection devices 210 can then be rotated to their desired positions to display images in combined projection area 505.

[0100] like Figure 5C As shown, when the vehicle 100 is halfway around the turn, both the projection devices 210 on the front and rear sides of the left door project images to present an image in a combined projection area 505. The combined projection area 505 includes a front projection area 503 projected by the projection device 210 on the front side of the left door and a rear projection area 504 projected by the projection device 210 on the rear side of the left door. Figure 5C The area ratio of the combined projection area 505 in Figure 5B The combined projection area 505 is larger. Figure 5B compared to, Figure 5C The handle in the illustrated embodiment is unfolded to a larger unfolding opening (including fully unfolded) so that less of the projection device 210 mounted thereon is blocked (including not blocked), and the front and rear projection devices 210 are each rotated to the desired position, thereby presenting images in a larger combined projection area 505.

[0101] like Figure 5D As shown, when the vehicle 100 is close to completing the turn, the projection devices 210 on the front and rear sides of the left door both project images to present an image in the combined projection area 505. Figures 5B-5C The combined projection area 505, Figure 5D The area of ​​the combined projection area 505 is the smallest. When the vehicle 100 completes the turn, the combined projection area 505 is substantially in a straight line. Figures 5B-5C compared to, Figure 5DIn the illustrated embodiment, the handle is unfolded to a smaller opening to block more of the projection device 210 mounted thereon, and the front and rear projection devices 210 are each rotated to a desired position, thereby presenting an image in the smallest combined projection area 505. In one embodiment, Figures 5B-5D The image displayed in the projection area 505 has no pattern and only appears red.

[0102] Figure 6 yes Figure 1 FIG. 1 is a block diagram of a vehicle door handle system 600, wherein the door handle system 600 is connected to a central controller 610 of the vehicle. Figure 6 As shown, the door handle system 600 includes a handle 101, a handle driving device 601, a projection device 210, a projection driving device 603, and a control device 602. The control device 602 is connected to the handle driving device 601, the projection device 210, and the projection driving device 603, and is configured to control the operations of these devices.

[0103] In one embodiment, the central controller 610 generates control signals for the door handle system 600 based on received vehicle signals to control the operation of the door handle system 600, thereby enabling the door handle system 600 to implement projection in various projection modes. Vehicle signals indicate the vehicle's operating status and may include, for example, a key approach signal, a door closed signal, a driver seated signal, a width indicator signal, a charging signal, an automated driving function activation signal (Adas signal), a turn signal, a vehicle speed signal, and a turning angle signal. The control signals for the door handle system 600 include a handle deployment / retraction control signal, a projection device motion control signal, and a projection device operation control signal. The handle deployment / retraction control signal indicates the deployment or retraction of the handle 101, the projection device motion control signal indicates the movement of the projection device 210 relative to the handle 101, and the projection device operation control signal indicates the selection of a projection head in the projection device 210 and the operating mode of the selected projection head. The control device 602 in the door handle system 600 receives control signals from the central controller 610 to generate drive control signals for the handle drive device 601, the projection drive device 603, and the projection device 210. The control device 602 thereby controls the operation of the handle drive device 601, the projection drive device 603, and the projection device 210 to project corresponding images in various projection modes. In other embodiments, the control device 602 implements the above-described control based on other appropriate signals.

[0104] The control device 602 is configured to generate a drive control signal for the handle actuator 601 to control the operation of the handle actuator 601, thereby causing the handle actuator 601 to move the handle 101 to expand or retract relative to the vehicle door. Deployment of the handle 101 includes extending the handle 101 to a certain opening. The projection device 210 and the projection actuator 603 are mounted to the handle 101 so that when the handle 101 moves, the projection device 210 moves accordingly.

[0105] The control device 602 is further configured to generate a drive control signal for the projection drive device 603 to control the operation of the projection drive device 603, so that the projection drive device 603 controls the movement of the projection device 210. The projection drive device 603 includes a first projection motor 311 and a second projection motor 312. The control device 602 is configured to generate a drive control signal for the first projection motor 311 to control the operation of the first projection motor 311 to drive the projection device 210 to rotate a desired angle about a first rotation axis, and to generate a drive control signal for the second projection motor 312 to control the operation of the second projection motor 312 to drive the projection device 210 to rotate a desired angle about a second rotation axis. The control device 602 independently controls the operation of the first projection motor 311 and the second projection motor 312.

[0106] Furthermore, the control device 602 is further configured to generate a drive control signal for the projection device 210 to control the operation of the projection device 210 to project a desired image. The projection device 210 includes a first projection head 301, a second projection head 302, and a third projection head 303. The control device 602 is configured to generate a drive control signal for the projection device 210 to control the light source of a corresponding projection head in the projection device 210, such as one of the first projection head 301, the second projection head 302, and the third projection head 303, and to control the operation of a chip associated with the light source of the corresponding projection head to control the color and duration of light emitted by the light source to project an image, thereby implementing various projection modes. In one embodiment, the projection device 210 is mounted on each door handle 101 of the vehicle. In other embodiments, the projection device 210 is mounted on an appropriate handle 101 of the vehicle. The control device 602 is configured to generate a driving control signal of the projection device 210 to selectively control at least one projection device 210 in the vehicle to operate and selectively control at least one projection head in the projection device 210 to operate to project an image for a desired projection mode.

[0107] In one embodiment, when each projection mode of the vehicle is activated, each component of the door handle system 600 begins operating from its initial position. Upon completion of each projection mode of the vehicle, each component of the door handle system 600 is reset to its initial position. For example, in the door handle system 600, the handle actuator 601 is reset to its initial position to move the handle 101 to its initial position, i.e., the handle 101 is retracted relative to the vehicle door. The projection actuator 603 is reset to its initial position to move the projection device 210 to its initial position relative to the handle 101. The projection head of the projection device 210 is reset to its initial position, for example, turning off the light source in the projection head and restoring the chip associated with the light source to its initial state.

[0108] In one embodiment, in the vehicle's welcome mode, when a vehicle user approaches the vehicle with a key, the central controller 610 generates a handle deployment control signal based on the key approach signal to instruct the handle 101 to fully deploy, and generates a projection device operation control signal to instruct a predetermined projection head in the projection device 210 to operate and project an image. The control device 602 generates a drive control signal for the handle drive device 601 based on the handle deployment control signal from the central controller 610 to control the handle drive device 601 to operate and drive the handle 101 to gradually deploy from an initial position (retracted position) to a fully deployed position. The control device 602 also generates a drive control signal for the projection device 210 based on the projection device operation control signal from the central controller 610 to control the light source of the corresponding projection head in the projection device 210, such as the first projection head 301, to activate and project a desired image, such as a pattern image. When the vehicle door is closed and the vehicle user sits in the driver's seat of the vehicle, the central controller 610 generates a reset control signal for the door handle system 600 based on the vehicle door closing signal and the driver sitting signal to control the various components of the door handle system 600 to reset to their initial positions.

[0109] In one embodiment, in the vehicle's width display mode, when the vehicle user presses the width display key, the central controller 610 generates a handle deployment control signal based on the width display signal to instruct the handle 101 to fully deploy, and generates a projection device operation control signal to instruct the selection of a predetermined projection head in the projection device 210 and for the projection head to project an image in a predetermined color. The control device 602 generates a drive control signal for the handle drive device 601 based on the handle deployment control signal from the central controller 610 to control the operation of the handle drive device 601 to drive the handle 101 from its initial position (retracted position) to fully deploy. The control device 602 also generates a drive control signal for the projection device 210 based on the projection device operation control signal from the central controller 610 to control the light source of a corresponding projection head in the projection device 210, such as the second projection head 302, to turn on, and to control the chip associated with the light source to project an image in a corresponding color, such as yellow. When the vehicle user dials back the width indication key, the central controller 610 generates a reset control signal for the door handle system 600 based on the width indication cancellation signal to control various components of the door handle system 600 to reset to their initial positions.

[0110] In one embodiment, the projection operations in the vehicle's charging mode and autonomous driving mode are similar to the projection operations in the width display mode described above. The difference is that in the vehicle's charging mode, the central controller 610 generates a handle deployment control signal and a projection device operation control signal based on the charging signal. The projection device operation control signal instructs a predetermined projection head in the projection device 210 to project a green image. The central controller 610 generates a reset control signal for the door handle system 600 based on the charging completion signal. In the vehicle's autonomous driving mode, the central controller 610 generates a handle deployment control signal and a projection device operation control signal based on the autonomous driving function activation signal (Adas signal). The projection device operation control signal instructs a predetermined projection head in the projection device 210 to project a blue image. The central controller 610 generates a reset control signal for the door handle system 600 based on the autonomous driving operation cancellation signal.

[0111] In one embodiment, in the vehicle's lane change mode, when the vehicle user presses the turn button, the central controller 610 generates a handle deployment control signal based on the turn signal to instruct the handle 101 on the vehicle side (the side to be changed lanes) to fully deploy, and generates a projection device operation control signal to instruct a predetermined projection head in the projection device 210 on the vehicle side to be selected and project an image of a predetermined color in a predetermined manner. The control device 602 generates a drive control signal for the handle drive device 601 based on the handle deployment control signal from the central controller 610 to control the operation of the handle drive device 601 on the vehicle side to drive the corresponding handle 101 from an initial position (retracted position) to fully deploy. The control device 602 also generates a drive control signal for the projection device 210 based on the projection device operation control signal from the central controller 610 to control the light source of the corresponding projection head in the projection device 210 on the vehicle side, such as the second projection head 302, to activate and operate the chip associated with the light source to project an image of a corresponding color in a corresponding manner, such as projecting a breathing yellow image. When the vehicle user returns the turn button, the central controller 610 generates a reset control signal of the door handle system 600 based on the turn cancellation signal to control various components of the door handle system 600 to reset to their initial positions.

[0112] In one embodiment, in a vehicle's turning mode, when a vehicle user turns the steering wheel and applies the brakes, the central controller 610 generates a handle deployment control signal based on the vehicle's turning angle signal and vehicle speed signal to indicate the deployment degree of the handle 101 on the vehicle side (the side toward which the turn is being made), generates a projection device motion control signal to indicate the rotation angles of the first projection motor 311 and the second projection motor 312 in the projection drive device 603 on the vehicle side, and generates a projection device operation control signal to select a predetermined projection head in the projection device 210 on the vehicle side and to project an image in a predetermined color. The control device 602 generates a drive control signal for the handle drive device 601 based on the handle deployment control signal from the central controller 610 to control the operation of the handle drive device 601 on the vehicle side to drive the corresponding handle 101 to deploy from an initial position (retracted position) to a corresponding deployment degree. The control device 602 generates drive control signals for the first projection motor 311 and the second projection motor 312 based on the projection device motion control signal from the central controller 610. This control signals controls the operation of the first projection motor 311 and the second projection motor 312 on one side of the vehicle, thereby driving the corresponding projection device 210 to rotate about the first rotation axis and the second rotation axis by a corresponding first rotation angle. The control device 602 also generates drive control signals for the projection device 210 based on the projection device operation control signal from the central controller 610, thereby controlling the light source of the corresponding projection head, such as the third projection head 303, in the projection device 210 on the vehicle side, and the operation of the chip associated with the light source to project an image of a corresponding color, such as red. When the vehicle user returns the turn button, the central controller 610 generates a reset control signal for the door handle system 600 based on the turn cancellation signal, thereby controlling the various components of the door handle system 600 to return to their initial positions. The unfolded opening of the handle 101 relative to the vehicle door and the first rotation angle of the projection device 210 around the first rotation axis and the second rotation angle around the second rotation axis are combined so that the projection device 210 projects an image of the required shape and area in the required projection area to indicate the dangerous area when the vehicle turns.

[0113] In other embodiments, the present application implements projection in each of the aforementioned projection modes and resets each projection mode upon completion through other suitable means. In one embodiment, the handle drive device 601 and the control device 602 are components of an actuator. The handle drive device 601 is the actuator's motor. The control device 602 is the actuator's controller. In other embodiments, the door handle system 600 includes other suitable structures.
