Detailed Description

The vehicle referred to in the following embodiments may be another type of vehicle such as a standard gasoline-powered vehicle, a hybrid vehicle, an electric vehicle, a fuel cell vehicle, a two-wheel or three-wheel vehicle, or the like. The vehicle may include mobility related components such as an engine (or motor), transmission, suspension, drive axles, wheels, and the like. The vehicle may also include components related to vehicle control such as controllers, vehicle buses, and the like. The controller can be connected with the electronic devices of the vehicle through the vehicle bus, so that the controller can control the electronic devices. The vehicle may be non-autonomous, semi-autonomous (e.g., some conventional motor functions are controlled by the vehicle), or autonomous (e.g., motor functions are controlled by the vehicle without direct driver input).

In the related art vehicle, in order to facilitate a user to easily find a target vehicle in a parking lot or a dark environment, it is possible to realize this by providing a display device on the outside of the vehicle. When the user searches for the target vehicle, the user can remotely trigger the controller of the vehicle through the portable device and control the display device to be started through the controller.

The existing display device comprises a projector and a water spray fog curtain, wherein the projector can project a projection graph on the water spray fog curtain to achieve the purpose of reminding a user. However, the conventional display device has the following disadvantages: the water mist screen system is too complex and complicated in layout, and water is guided from positions such as an engine room and a back door; the water source is not automatically full, manual water adding is needed, and if the water is not stored in time, the water is exhausted and loses efficacy; when the water spray fog curtain is sprayed, the vehicle (vehicle body) can be polluted; the water mist jet has a certain divergence angle and can be sprayed to people or things beside the vehicle. When the service environment has strong wind weather, the fog screen can swing along with the wind, so that the holographic projection is not clear or cannot be displayed on the fog screen.

From the above, the main disadvantage of the prior art is the water mist screen. In order to overcome the defects of the water mist screen in the prior art, the inventor of the application modifies the screen projected by the projector. The screen may be subject to a large air resistance during the running of the vehicle, and the larger the size of the screen, the greater the resistance the screen is subjected to. In order to minimize the size of the screen, the inventor of the present application designs the curtain assembly by using the principle of persistence of vision.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

Fig. 1 is a schematic view of a vehicle according to an embodiment of the present disclosure, fig. 2 is a schematic view of a projector 3 of the vehicle according to the embodiment of the present disclosure projected on a curtain assembly 2, fig. 3 is a front view of the curtain assembly 2 shown in fig. 2, fig. 4 is a schematic view of a blade 22 of the curtain assembly 2 shown in fig. 3 at a certain moment during rotation, and fig. 5 is a schematic view of a vehicle according to the embodiment of the present disclosure. Referring to fig. 1-5, a vehicle may include a body 1, a curtain assembly 2, a projector 3, and a controller 4.

The vehicle body 1 refers to a structural part of a vehicle for loading people. The vehicle body 1 may include windows, doors, a cockpit, a passenger compartment, an engine compartment, a luggage compartment, and the like. The vehicle body 1 may have a mounting portion 11, and the curtain assembly 2 may be mounted on the mounting portion 11. To facilitate easier vehicle locating by a user, the curtain assembly 2 may be generally disposed on the ceiling of the passenger compartment, i.e., the mounting portion 11 may generally be the ceiling of the passenger compartment as shown in fig. 1.

Referring to fig. 3-5, the curtain assembly 2 may include a bracket 21, a vane 22, and a first drive 23. The bracket 21 may be disposed on the mounting portion 11, the blade 22 may be hinged to the bracket 21, and the first driver 23 may be mounted on the bracket 21 and configured to drive the blade 22 to rotate and enable the blade 22 to form an afterimage.

Specifically, a first end of the bracket 21 (a lower end of the bracket 21 shown in fig. 3 and 4) may be provided on the base 13 of the mounting portion 11. The second end of the bracket 21 (the upper end of the bracket 21 shown in fig. 3 and 4) may be provided with a vane 22. The blade 22 is rotatably disposed at the second end of the bracket 21 by a rotating shaft 25. Alternatively, the first driver 23 may comprise a motor, and a motor shaft of the motor may be connected to the rotating shaft 25 and may drive the rotating shaft 25 to rotate, so as to drive the blades 22 to rotate. The motor shaft and the rotating shaft 25 can be directly connected by welding, clamping connection, interference fit, shaft coupling and the like. The motor shaft and the rotating shaft 25 can also be indirectly connected through an intermediate member such as a reducer.

It should be noted that when the speed of the eye capturing the rotating blade 22 is not as fast as the rotating speed of the blade 22, the eye cannot see the position of the blade 22 in motion. However, due to the effect of persistence of vision, the eye can see an image of the position in front of the leaf 22, which is called an afterimage. The faster the rotation speed of the blade 22, the more afterimages are seen by the eyes.

For example, in fig. 4, the rotation axis of the blade 22 may be located in the middle of the blade 22, and the blade 22 may have an elongated shape. As the leaflets 22 rotate counterclockwise or clockwise from the A1 position to the A2 position, the eye still sees the afterimage 7 of the position that the leaflets 22 pass through during rotation. In fact, the blade 22 in fig. 4 forms more residual shadows 7 after half a rotation than that shown in fig. 4, and there is no distinct edge line between two adjacent residual shadows 7. The plurality of afterimages 7 can fill the closed figure surrounded by the motion tracks of the outermost edges of the blades 22 to form a complete afterimage. Illustratively, in fig. 2 and 4, the plurality of afterimages 7 of the rotated blade 22 may fill the circles drawn by the dashed lines in fig. 2 and 4. It should be noted that if the rotation axis of the elongated blade 22 is located at the end of the blade 22, the blade 22 can form a complete afterimage after one rotation. In addition, how much the blade 22 rotates to form a complete afterimage depends not only on the position of the rotational axis of the blade 22 but also on the shape of the blade 22.

Referring to fig. 2, the projector 3 may be disposed on the mounting portion 11 and may be disposed opposite to the curtain assembly 2. The projector 3 is used to project a preset pattern onto the blade 22. Specifically, when the light emitted from the projector 3 is applied to the blade 22, the pattern 6 is partially projected on the surface of the blade 22. Due to persistence of vision, the eye can also see a portion of the projected pattern 6 on the afterimage 7. The partial projected patterns 6 on the plurality of afterimages 7 are combined together to form the projected pattern 6 shown in fig. 2. It should be noted that the projection pattern 6 may be set by the user or may be set at the time of factory shipment. The projected pattern 6 in fig. 2 is only an example and is not particularly limited.

Referring to fig. 5, an input of the controller 4 may be configured to receive a control command input by a user from the portable device 8, and an output of the controller 4 may be communicatively coupled to the first driver 23 and the projector 3. The controller 4 can control the on/off of the first driver 23 and the projector 3 according to a control command input by a user.

Specifically, the controller 4 is communicably connected to the projector 3, the first driver 23, and the portable device. Of course, the device with which the controller 4 can communicate may also include a cloud, other components on the vehicle (e.g., vehicle-mounted camera, seat sensor, human-machine interface, etc.). Illustratively, the controller 4 may be communicatively coupled with a human machine interface. This information may be transmitted and stored in the controller 4 when an occupant of the vehicle inputs, selects or customizes the image desired to be projected via the human-machine interface. The controller 4 may then transmit the image to the projector 3 of the present application as needed.

In addition, the portable device may include at least: a vehicle key, a smart phone key (PAAK), a smart phone, a mobile phone, a Personal Digital Assistant (PDA), an MP3, a tablet computer, or a Portable Multimedia Player (PMP). The portable device may be carried by an occupant of the vehicle, and the controller 4 may detect a signal from the portable device. Additionally, the occupant of the vehicle may also generate control commands by pressing buttons on the portable device and/or activating applications thereon. When the controller 4 detects a control command from the portable device, the controller 4 may control the on/off of the first driver 23 and the projector 3 according to the control command.

In summary, in the vehicle provided by the present application, the bracket 21 is disposed on the mounting portion 11, the blade 22 is hinged to the bracket 21, the blade 22 can be driven by the first driver 23 to rotate, the afterimages 7 of the blades 22 can be obtained, the afterimages 7 of the blades 22 can form an afterimage, and the preset image is projected onto the blade 22, so that the complete projection image 6 can be displayed on the afterimage, and the function of prompting the user is achieved, the curtain assembly 2 is simple in structure, and the maintenance of the user is more convenient compared with a display device in the related art.

Fig. 6 is another schematic diagram of a vehicle according to an embodiment of the present disclosure. In order to make the projections of the projector 3 fall on the curtain assembly 2 during operation, referring to fig. 6, the input of the controller 4 may be further communicatively connected with a rotation speed detector 51, and the rotation speed detector 51 may be used to detect the rotation speed of the blade 22. The controller 4 may be configured to control the projector 3 to be turned on when the rotation speed of the blade 22 measured by the rotation speed detector 51 is greater than or equal to a preset rotation speed. Wherein the rotation speed detector 51 may also be used to feed back the rotation speed of the blades 22 to the controller 4. In addition, the rotation speed detector 51 may be a current detector capable of detecting the output current of the first driver 23. The rotation speed of the blade 22 can be indirectly obtained by the output current value of the first driver 23.

In addition, in order to avoid that the user forgets to turn off the first driver 23 and the projector 3, the input of the controller 4 may be communicatively connected with a distance detector 52, and the distance detector 52 may be used to detect the distance between the portable device 8 and the vehicle. The controller 4 may control the first driver 23 and the projector 3 to be turned off when the distance measured by the distance detector 52 is less than or equal to a preset distance value.

FIG. 7 is a partial schematic view of a bucket 22 according to an embodiment of the present disclosure. In order to make the projected pattern 6 on the blade 22 more clear, referring to fig. 7, the surface of the blade 22 facing the projector 3 may be provided with a reflective layer 221. Illustratively, the reflective layer 221 may be a fine grit aluminized layer. In addition, in order to make the projected pattern 6 on the blade 22 flat for the user to observe. Alternatively, the surface of the blade 22 facing the projector 3 may be a plane.

It will be appreciated that the curtain assembly 2 may experience greater air resistance during vehicle travel, and the greater the area of the curtain assembly 2, the greater the resistance experienced by the curtain assembly 2. In order to reduce the area of the curtain assembly 2 when not in operation, i.e. to reduce the area of the curtain assembly 2 when the first actuator 23 is stalled, the controller 4 is optionally further configured to control the first actuator 23 to rotate the vane 22 to an initial position according to a closing command input by a user, the initial position being configured such that the vane 22 is perpendicular to the mounting portion 11.

Specifically, the controller 4 may record an initial angle value corresponding to the initial position of the blade 22 as an initial angle and store the initial angle value. When the controller 4 receives a closing instruction sent by the portable device, the angle value corresponding to the current position of the blade 22 is obtained, and the angle value is recorded as the current angle. The controller 4 may calculate a difference between the current angle and the initial angle and rotate the vane 22 to the initial position by controlling the first driver 23 to rotate the vane 22 by the difference angle. Wherein the controller 4 may acquire the rotation angle of the blade 22 through an angle sensor. An angle sensor may be used to measure the angle of rotation of the motor shaft of the first actuator 23 or the angle of rotation of the vane 22.

FIG. 8 is a schematic view of the curtain assembly 2 shown in FIG. 3 with its vanes 22 in an initial position. Referring to fig. 8, the reason why the initial angle of the vane 22 is set to be perpendicular to the mounting portion 11 is that the bracket 21 is disposed perpendicular to the mounting portion 11 when the curtain assembly 2 is operated, so that the bottom end of the vane 22 hinged to the bracket 21 can have a certain distance from the surface of the mounting portion 11 to prevent the vane 22 from colliding with the surface of the mounting portion 11 after rotating. When the blades 22 are perpendicular to the installation, the stacking area between the blades 22 and the bracket 21 is large, which is beneficial to improving the wind resistance of the curtain assembly 2. Further, referring to fig. 11, the bracket 21 and the blade 22 can be received in the groove 12 of the mounting portion 11, and the larger the lamination area between the blade 22 and the bracket 21, the smaller the size of the groove 12 for accommodating the blade 22 and the bracket 21.

In order to reduce the air resistance of the curtain assembly 2 during the running process of the vehicle, the windward height of the curtain assembly 2 can be reduced as much as possible when the curtain assembly 2 does not work. This application is realized by setting the stand 21 to be liftable. In order to minimize the structural variations of the mounting portion 11 of the vehicle body 1, the bracket 21 may be hinged to the base 13 of the mounting portion 11, and the bracket 21 may have an expanded state perpendicular to the mounting portion 11 as shown in fig. 9 and a closed state parallel to the mounting portion 11 as shown in fig. 10.

Referring to fig. 5, 9 and 10, the mounting portion 11 may be mounted with a second actuator 24, and the second actuator 24 may be used to drive the bracket 21 to rotate to the open state and the closed state. The unfolded state may be configured such that the hinge of the bracket 21 and the blade 22 has a first preset height with the mounting portion 11. The closed state may be configured such that the hinge of the bracket 21 and the blade 22 has a second preset height with the mounting portion 11. The second preset height is smaller than the first preset height. The controller 4 may control the second driver 24 to rotate the bracket 21 to the open state or the closed state according to a control command input by a user.

For example, referring to fig. 5, when the user finds a vehicle, the user may send an opening command to the controller 4 through the portable device 8, and the controller 4 may generate an opening control signal after receiving the opening command. The second driver 24 can drive the bracket 21 to rotate from the closed state shown in fig. 10 to the open state shown in fig. 9 after receiving the opening control signal sent by the controller 4. The controller 4 may also determine whether the support 21 is rotated to the expanded state according to the rotation angle of the support 21 fed back by the angle sensor. The controller 4 may control the first driver 23 to operate after the bracket 21 is in the unfolded state, so that the blades 22 start to rotate. The controller 4 may determine whether the rotation speed of the blade 22 reaches a preset rotation speed by the rotation speed of the blade 22 fed back by the rotation speed detector 51. The controller 4 may control the projector 3 to be turned on to project on the vane 22 after the rotation speed of the vane 22 reaches a preset angle. After the user sees the projection on the blade 22, it gradually approaches the target vehicle.

In addition, the user can turn off the projection by the portable device 8 or a control switch in the vehicle when the projection is not needed or when the user is seated in the vehicle. Of course, the controller 4 may determine whether the user needs to project the image based on the distance from the portable device 8 to the vehicle, which is fed back by the distance detector 52. The controller 4 may turn off the projection when the distance between the portable device 8 and the vehicle is equal to or less than a preset distance.

In addition, to facilitate the storage of the curtain assembly 2, the controller 4 may control the first driver 23 to rotate the vane 22 to the initial position shown in fig. 8 by the angle value of the vane 22 fed back by the angle sensor. After the vanes 22 are in the initial position, the controller 4 may control the second driver 24 to rotate the bracket 21 from the expanded state shown in fig. 9 to the closed state shown in fig. 10.

To facilitate reducing the size of the groove 12, with reference to fig. 9-11, optionally, the axis of rotation of the bracket 21 is parallel to the axis of rotation of the blade 22. In addition, the blades 22 and the bracket 21 may be flat rods to reduce the size of the curtain assembly 2. In addition, the mounting portion 11 may be provided with a groove 12 for hiding the curtain assembly 2. The recess 12 may have an upwardly facing opening, the recess 12 receiving the frame 21 in the closed position.

Referring to fig. 2, 9, and 10, in order to make the projector 3 as close as possible to the mounting portion 11 of the vehicle body 1 while ensuring that the projection pattern 6 projected by the projector 3 is at a target height, the mounting axis of the projector 3 may be inclined upward with respect to the surface of the mounting portion 11.
