Abstract

This application discloses a head-up display (HUD) device and vehicle, belonging to the field of automotive intelligent electronics. The HUD device includes a display module, a support base, a reflector assembly, and a moving component. Since the moving component can move the reflector assembly closer to or further away from the display module, and also closer to or further away from the support base, the size of the virtual image displayed on the windshield can be changed by altering the distance between the reflector assembly and the display module. This allows drivers to adjust the size and distance of the virtual image displayed on the windshield according to their driving habits and needs. Even if the imaging distance of the virtual image of the HUD device varies significantly due to the curvature error of the windshield, the actual display effect can still be guaranteed. Furthermore, even if there is a large deviation between the theoretical and actual installation positions, drivers can adjust them themselves, further reducing installation costs.

Description

Technical Field

[0001] This application relates to the field of automotive intelligent electronics, and in particular to a head-up display device and vehicle. Background Technology

[0002] Augmented Reality-Head-Up Display (AR-HUD) is a type of automotive vision-assisted safety driving system. This system projects important information needed by the driver onto the windshield of the car through the optical path of the AR-HUD, integrating the displayed information with the surrounding real scene. This allows the driver to directly obtain real-time road condition information and vehicle-related information on the windshield.

[0003] Current AR-HUD devices suffer from significant limitations due to the manufacturing process tolerances of vehicle windshields. This results in the radius of curvature of the glass fluctuating between 3000mm and 7000mm, leading to substantial variations in the imaging distance of the virtual image. This not only affects the actual display effect but also frequently results in significant discrepancies between the theoretical and actual installation positions, necessitating retesting and reinstallation, further increasing installation costs.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] This application provides a head-up display device, which can be an AR-HUD. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a head-up display device provided in this application. Figure 2 This is an optical path diagram of an image beam provided in one embodiment of this application. The head-up display device 00 can be installed in the cockpit of a vehicle, and the head-up display device 00 may include: a display module 20, a support base 10, a reflector group 30, and a moving component 40.

[0040] The display module 20 in the head-up display device 00 is connected to the support base 10, and the light-emitting side of the display module 20 faces the reflective side of the reflector group 30. The display module 20 is used to acquire image information and emit an image beam to the reflector group 30 based on the image information. The reflector group 30 is used to reflect the image beam to the windshield 01 of the vehicle to form a virtual image on the windshield 01.

[0041] For example, the light-emitting side of the display module 20 is aligned with the reflective side of the reflector group 30 to reflect the image beam onto the windshield 01, forming a virtual image on the windshield 01 for observation by occupants of the vehicle. Occupants of the vehicle may include at least one of a driver and passengers.

[0042] The reflector assembly 30 in the head-up display device 00 is connected to the support base 10 via a moving component 40. This moving component 40 can be configured to move the reflector assembly 30 in a direction toward or away from the display module 20 (i.e., Figure 1 The mirror assembly 30 moves in the Y direction and moves towards or away from the support 10, i.e., Figure 1 (Move in the X direction).

[0043] In this embodiment, the moving component 40 moves the reflector group 30 closer to or further away from the display module 20. According to the imaging principle, when the reflector group 30 is closer to the display module 20, the virtual image displayed on the windshield 01 is closer to the driver, and the virtual image displayed on the windshield 01 is smaller. When the reflector group 30 is further away from the display module 20, the virtual image displayed on the windshield 01 is farther from the driver, and the virtual image displayed on the windshield 01 is larger. This allows the driver to adjust the size and distance of the virtual image displayed on the windshield 01 according to their driving habits and needs, ensuring the actual display effect.

[0044] Furthermore, the movable component 40 can also move the reflector group 30 closer to or further away from the support base 10. According to the imaging law, when the reflector group 30 moves closer to or further away from the support base 10, the virtual image displayed on the windshield 01 will move in the opposite direction to the direction of movement of the reflector group 30. This allows different drivers to adjust the position of the virtual image displayed on the windshield 01 according to their height requirements, thus improving the actual display effect.

[0045] In summary, the head-up display device provided in this application includes: a display module, a support base, a reflector assembly, and a moving component. Since the reflector assembly is connected to the support base via the moving component, and the moving component can move the reflector assembly closer to or further away from the display module, as well as closer to or further away from the support base, the size of the virtual image displayed on the windshield can be changed by altering the distance between the reflector assembly and the display module. This allows drivers to adjust the size and distance of the virtual image displayed on the windshield according to their driving habits and needs, ensuring a consistent display effect. Furthermore, the position of the virtual image displayed on the windshield can be changed by altering the distance between the reflector assembly and the support base, allowing different drivers to adjust the position of the virtual image displayed on the windshield according to their height requirements, thus improving the overall display effect. In this way, even if the imaging distance of the virtual image in the head-up display device varies significantly due to the curvature error of the windshield, the overall display effect can still be guaranteed. Simultaneously, even if there is a large deviation between the theoretical and actual installation positions, drivers can adjust them themselves, further reducing installation costs.

[0046] In this embodiment, the support base 10 of the head-up display device 00 can be integrated into the vehicle's sub-dashboard. Here, the vehicle's sub-dashboard refers to the component located between the driver's seat and the passenger seat. It should be noted that by integrating the support base 10 into the vehicle's sub-dashboard, the head-up display device does not need to be located between the driver's dashboard and the windshield, thus reducing the space occupied by the head-up display device 00 in the cockpit.

[0047] Optionally, such as Figure 3 As shown, Figure 3 This is a structural diagram of another head-up display device 00 provided in an embodiment of this application. The reflector group 30 may include a first reflector 310, a second reflector 320, and a third reflector 330 arranged sequentially. The second reflector 320 may be located between the first reflector 310 and the third reflector 330, and is connected to both the first reflector 310 and the third reflector 330. Here, the first reflector 310 in the reflector group 30 refers to a reflector distributed towards the driver's seat of the vehicle, and the third reflector 330 in the reflector group 30 refers to a reflector distributed towards the passenger's seat of the vehicle.

[0048] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, Figure 4This is another embodiment of the optical path diagram of an image beam provided in this application. The image beam emitted by the display module 20 can include various types. This embodiment of the application uses the following four types of image beams emitted by the display module 20 as examples for illustration:

[0049] It should be noted that, for ease of understanding and explanation, the windshield 01 is divided into a first area A1, a second area A2, and a third area A3. The second area A2 can be located between the first area A1 and the third area A3.

[0050] In a first possible implementation, the display module 20 is used to acquire image information of the vehicle's assisted driving, and based on the image information of the assisted driving, emits a first beam of light to the first reflector 310, so that the first reflector 310 reflects the first beam of light onto the windshield 01, forming a first virtual image on the windshield 01 for the driver of the vehicle to view.

[0051] The driver assistance image information may include: vehicle speed information, road information acquired during vehicle operation, vehicle remaining fuel or remaining battery power information, and other information related to vehicle driving.

[0052] For example, the control system in the vehicle can generate vehicle-related assisted driving image information, and the vehicle control system can send this assisted driving image information to the display module 20 in the head-up display device 00, so that the display module 20 can obtain this assisted driving image information.

[0053] In this case, please refer to Figure 4 The display module 20 can emit a first beam of light towards the first reflector 310 based on the acquired assisted driving image information, and then project the first beam of light into the first area A1 of the windshield 01 through the first reflector 310, so as to form a first virtual image screen for the driver to view within the first area A1 of the windshield 01. In this way, the driver can view assisted driving images related to driving while the vehicle is in motion.

[0054] In a second possible implementation, the display module 20 is used to acquire first streaming media image information and, based on the first streaming media image information, emit a second beam of light to at least one of the second reflector 320 and the third reflector 330, so that at least one of the second reflector 320 and the third reflector 330 reflects the second beam of light onto the windshield 01, thereby forming a second virtual image on the windshield 01 for passengers inside the vehicle to view.

[0055] The first streaming media image information may include: audio image information, video image information, and multimedia image information, as well as other media information that can form a beam of light and be projected onto the windshield 01.

[0056] For example, relevant command signals can be sent to the vehicle control system via a user's mobile device, and then the vehicle control system can generate relevant streaming media video information and send it to the display module 20, so that the display module 20 can obtain this streaming media video information.

[0057] In this configuration, the display module 20 can emit a second beam of light to at least one of the second reflector 320 and the third reflector 330 based on the acquired first streaming media image information. This causes the second reflector 320 and the third reflector 330 to reflect the second beam of light into the second area A2 and / or the third area A3 corresponding to the windshield 01, thereby forming a second virtual image for passengers inside the vehicle to view. This allows passengers to view streaming media images while the vehicle is in motion or when the vehicle is stationary.

[0058] In a third possible implementation, the display module 20 is used to simultaneously acquire assisted driving image information and first streaming media image information, and based on the assisted driving image information, emits a first beam of light to the first reflector 310, so that the first reflector 310 reflects the first beam of light onto the windshield 01, forming a first virtual image on the windshield 01 for the driver of the vehicle to view. At the same time, based on the first streaming media image information, it emits a second beam of light to at least one of the second reflector 320 and the third reflector 330, so that at least one of the second reflector 320 and the third reflector 330 reflects the second beam of light onto the windshield 01, forming a second virtual image on the windshield 01 for the passengers inside the vehicle to view.

[0059] In this configuration, the display module 20 can simultaneously acquire assisted driving image information and first streaming media image information. Based on the assisted driving image information, it emits a first beam of light towards the first reflector 310, and simultaneously, based on the acquired first streaming media image information, emits a second beam of light towards at least one of the second reflector 320 and the third reflector 330. This causes the first reflector 310 to reflect the first beam of light onto the first area A1 corresponding to the windshield 01, and causes at least one of the second reflector 320 and the third reflector 330 to reflect the second beam of light onto the second area A2 and / or the third area A3 corresponding to the windshield 01. This allows a first virtual image for the driver to observe and a second virtual image for passengers inside the vehicle to view simultaneously on the windshield 01. Thus, during vehicle operation, not only can the driver view driving-related assisted driving images, but passengers can also view streaming media images.

[0060] In a fourth possible implementation, the display module 20 is used to acquire second streaming media image information and, based on the second streaming media image information, simultaneously emits a third beam of light to the first reflector 310, the second reflector 320 and the third reflector 330, so that the first reflector 310, the second reflector 320 and the third reflector 330 simultaneously reflect the third beam of light onto the windshield 01, thereby forming a second virtual image on the windshield 01 for all occupants of the vehicle to view.

[0061] In this configuration, the display module 20 can simultaneously emit a third beam of light to the first reflector 310, the second reflector 320, and the third reflector 330 based on the acquired second streaming media image information. This third beam is projected onto all areas of the windshield 01, including the first area A1, the second area A2, and the third area A3, forming a second virtual image that can be viewed simultaneously by all occupants of the vehicle, including the driver and passengers. Thus, even when the vehicle is stationary, the entire windshield displays the second virtual image, allowing all occupants to view a large-area streaming media image, effectively improving the playback effect when the vehicle is stationary.

[0062] In this application, as Figure 3 and Figure 4 As shown, the display module 20 can be configured in various ways. This application describes two embodiments:

[0063] In the first embodiment, please refer to Figure 4 The display module 20 may have: a first display area B1 opposite to the first reflector 310, a second display area B2 opposite to the second reflector 320, and a third display area B3 opposite to the third reflector 330. Here, the head-up display device 00 may include a display screen, and the first display area B1, the second display area B2, and the third display area B3 may be different areas on the display screen. The position of the first display area B1 may correspond to the driver, and the positions of the second display area B2 and the third display area B3 may correspond to the passengers inside the vehicle.

[0064] In this embodiment, different display areas can have different light emission modes. This application embodiment will illustrate the following four possible scenarios:

[0065] In the first possible scenario, the first display area B1 in the display module 20 can be used to emit a first beam. Here, the first display area B1 can emit a first beam towards the first reflector 310 based on the acquired assisted driving image information, and then the first reflector 310 projects the first beam into the first area A1 on the windshield 01 to form a first virtual image for the driver to view.

[0066] In a second possible scenario, at least one of the second display area B2 and the third display area B3 in the display module 20 is used to emit the second beam. Here, at least one of the second display area B2 and the third display area B3 can emit the second beam towards at least one of the corresponding second reflector 320 and the third reflector 330 based on the acquired first streaming media image information, so that at least one of the second reflector 320 and the third reflector 330 reflects the second beam into the first area A1 and / or the third area A3 corresponding to the windshield 01, forming a second virtual image for passengers inside the vehicle to view.

[0067] In a third possible scenario, the first display area B1 in display module 20 is used to emit the first light beam, and at least one of the second display area B2 and the third display area B3 in display module 20 is used to emit the second light beam. Here, the first display area B1 can emit the first light beam to the first reflector 310 based on assisted driving image information, and one of the second display area B2 or the third display area B3 can emit the second light beam to at least one of the corresponding second reflector 320 and the third reflector 330 based on the first streaming media image information, so that during driving, a first virtual image for the driver to observe and a second virtual image for the passengers inside the vehicle can be simultaneously formed on the windshield 01. Here, the first virtual image can be an assisted driving image; the second virtual image can be a streaming media image.

[0068] In a fourth possible scenario, the first display area B1 and the second display area B2 in the display module 20 are used to simultaneously emit the third beam. The first display area B1 and the second display area B2 can simultaneously emit the third beam towards the first reflector 310, the second reflector 320, and the third reflector 330, projecting the third beam onto all areas of the windshield 01, including the first area A1, the second area A2, and the third area A3, thus forming a second virtual image on the entire windshield for simultaneous viewing by all occupants of the vehicle, including the driver and passengers. In this case, the second virtual image can be a panoramic streaming media image played when the vehicle is parked.

[0069] It should be noted that in the first embodiment, by partitioning the display module 20 as described above, the first display area B1 corresponds one-to-one with the first reflector 310, the second display area B2 with the second reflector 320, and the third display area B3 with the third reflector 330. When the driver or passengers do not wish to view the screen, the display area corresponding to the passenger or driver can be turned off, thus preventing an image from forming on the windshield corresponding to the person who does not wish to view the screen, thereby adjusting the view observed by different passengers.

[0070] In the second embodiment, please refer to Figure 3 The head-up display device 00 further includes a rotating component 50, wherein the display module 20 is connected to the support base 10 via the rotating component 50, and the rotating component 50 is configured to drive the display module 20 to rotate relative to the support base 10.

[0071] In this embodiment, the rotating component 50 can have different effects depending on the different light beams emitted by the display module 20. The embodiments of this application are described in the following four ways:

[0072] In a first embodiment, the rotating component 50 is used to drive the display module 20 to rotate relative to the support base 10, so that the light-emitting side of the display module 20 faces the first reflector 310, so that the display module 20 can emit the first light beam toward the first reflector 310.

[0073] Here, by rotating the support base 10 via the rotating component 50, the light-emitting side of the display module 20 is directed only towards the first reflector 310. That is, while the light-emitting side of the display module 20 faces the first reflector 310, it does not face the second reflector 320 or the third reflector 330. At this time, the display module 20 receives assisted driving image information, and the first light beam emitted based on this image information is reflected by the first reflector 310 onto the windshield 01 to form a first virtual image for the driver to observe. Here, the first virtual image may include the assisted driving image.

[0074] In the second embodiment, the rotating component 50 is used to drive the display module 20 to rotate relative to the support base 10, so that the light-emitting side of the display module 20 faces at least one of the second reflector 320 and the third reflector 330.

[0075] Here, the light-emitting side of the display module 20 can be rotated by the rotating component 50 to face at least one of the second reflector 320 and the third reflector 330. That is, by rotating the rotating component 50 relative to the support base, the light-emitting side of the display module 20 can face both the second and third reflectors simultaneously, or only one of them. At this time, the display module 20 receives first streaming media image information, and the second light beam emitted based on this streaming media image information is reflected by at least one of the second reflector 320 or the third reflector 330 onto the windshield 01 to form a second virtual image for passengers to observe. Here, the second virtual image may include the streaming media image.

[0076] In the third embodiment, the rotating component 50 is used to drive the display module 20 to rotate relative to the support base 10, so that the light-emitting side of the display module 20 simultaneously faces at least one of the first reflector 310, the second reflector 320, and the third reflector 330.

[0077] Here, by rotating the rotating component 50, the light-emitting side of the display module 20 can be rotated to face the first reflector 310 while simultaneously facing at least one of the second reflector 320 and the third reflector 330. At this time, the display module 20 can simultaneously emit the first beam and the second beam, that is, the display module 20 can simultaneously form a first virtual image for the driver to observe and a second virtual image for the passengers to observe on the windshield 01 during driving.

[0078] In the fourth embodiment, the rotating component 50 is used to drive the display module 20 to rotate relative to the support base 10, so that the light-emitting side of the display module 20 simultaneously faces the first reflector 310, the second reflector 320 and the third reflector 330, so that the display module 20 can simultaneously emit the third light beam toward the first reflector 310, the second reflector 320 and the third reflector 330.

[0079] Here, by rotating component 50, the light-emitting side of display module 20 can simultaneously face the first reflector 310, the second reflector 320, and the third reflector 330. At this time, display module 20 can emit a third beam of light that is simultaneously reflected by the three reflectors; that is, display module 20 can form a second virtual image on the windshield 01 that is simultaneously visible to occupants of the vehicle, including the driver and passengers. Here, the second virtual image may include a panoramic streaming media image played when the vehicle is parked.

[0080] In the second embodiment, the driver can correspond to the first reflector 310, and the passenger can correspond to the second reflector 320 and / or the third reflector 330. It should also be noted that the rotating component 50 can be the output end of a rotating drive, which can include one of a motor, a cylinder, or a rotary motor. When the driver or passenger does not wish to view the image, the rotating component 50 can rotate the display module 20 relative to the support base 10, so that the light-emitting side of the display module 20 is not facing the reflector corresponding to the person who does not wish to view it. This prevents an image from being formed on the windshield in front of the person who does not wish to view the image, thus adjusting the view observed by different passengers.

[0081] Alternatively, please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of another head-up display device 00 provided in an embodiment of this application. The reflector group 30 further includes: a first hinge mechanism located between the first reflector 310 and the second reflector 320, and a second hinge mechanism located between the second reflector 320 and the third reflector 330. The second reflector 320 is rotatably connected to the first reflector 310 via the first hinge mechanism, and is rotatably connected to the third reflector 330 via the second hinge mechanism.

[0082] It should be noted that the pivots of the first and second hinge mechanisms can be parallel to the plane containing the reflective side of the first reflector 310. This allows the second reflector 320 and the third reflector 330 to be folded onto the first reflector 310 when not in use, resulting in a more compact arrangement of the reflector assembly 30 and reducing the possibility of the reflectors within the assembly breaking due to impact when not in use. Furthermore, the moving component 40 and the support base 10 can be rotatably connected, allowing the moving component 40 to also be folded onto the support base 10, further enhancing the internal compactness of the head-up display device 00 and helping to reduce the likelihood of wear on the reflectors in the reflector assembly 30.

[0083] Alternatively, please refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of another head-up display device 00 provided in an embodiment of this application. The movable component 40 includes: a telescopic rod 410, one end of which is connected to the support base 10, and the other end of which is fixedly connected to the reflector assembly 30. The telescopic rod 410 is capable of extending and retracting along its length.

[0084] Here, the telescopic rod 410 includes a first telescopic rod 4110 and a second telescopic rod 4120. The first telescopic rod 4110 has a first opening at its end near the support base 10. The size of the first opening is slightly larger than the size of the end of the second telescopic rod 4120 away from the support base 10, so that the end of the second telescopic rod 4120 away from the support base 10 can be inserted into the first opening and slidably connected to it. When the second telescopic rod 4120 slides along the direction near the end of the first telescopic rod 4110 away from the first opening, the reflector assembly 30 moves closer to the support base 10; when the second telescopic rod 4120 slides along the direction away from the end of the first telescopic rod 4110 away from the first opening, the reflector assembly 30 moves away from the support base 10.

[0085] Alternatively, please refer to Figure 6 The support base 10 has a slide rail 60, and one end of the telescopic rod 410 facing the support base 10 is located inside the slide rail 60 and slidably connected to the support base 10. The telescopic rod 410 is also capable of moving along the length of the slide rail 60.

[0086] Here, the end of the second telescopic rod 4120 near the support base 10 can be directly slidably connected to the support base 10. A pulley can be provided at the end of the second telescopic rod 4120 near the support base 10, and the pulley can be slidably connected to the slide rail 60. In this case, the reflector group 30 can move closer to or away from the display module 20 as the second telescopic rod 4120 slides along the length of the slide rail 60.

[0087] Alternatively, please refer to Figure 6 The moving assembly 40 further includes a first driving component and a second driving component connected to the telescopic rod 410. The first driving component is configured to extend and retract the telescopic rod 410 along its length, and the second driving component is configured to move the telescopic rod 410 along the length of the slide rail 60.

[0088] For example, the output end of the first driving component can be connected to either the first telescopic rod 4110 or the second telescopic rod 4120 to drive the first telescopic rod 4110 and the second telescopic rod 4120 to slide relative to each other; alternatively, the output end of the second driving component can be connected to at least one of the first telescopic rod 4110 and the second telescopic rod 4120 to drive at least one of the first telescopic rod 4110 and the second telescopic rod 4120 to slide along the length direction of the slide rail 60. In this embodiment, the first driving component and the second driving component can be linear driving components, which include at least one of a piston-linkage mechanism, a push rod, and a lead screw.

[0089] In summary, the head-up display device provided in this application includes: a display module, a support base, a reflector assembly, and a moving component. Since the reflector assembly is connected to the support base via the moving component, and the moving component can move the reflector assembly closer to or further away from the display module, as well as closer to or further away from the support base, the size of the virtual image displayed on the windshield can be changed by altering the distance between the reflector assembly and the display module. This allows drivers to adjust the size and distance of the virtual image displayed on the windshield according to their driving habits and needs, ensuring a consistent display effect. Furthermore, the position of the virtual image displayed on the windshield can be changed by altering the distance between the reflector assembly and the support base, allowing different drivers to adjust the position of the virtual image displayed on the windshield according to their height requirements, thus improving the overall display effect. In this way, even if the imaging distance of the virtual image in the head-up display device varies significantly due to the curvature error of the windshield, the overall display effect can still be guaranteed. Simultaneously, even if there is a large deviation between the theoretical and actual installation positions, drivers can adjust them themselves, further reducing installation costs.

[0090] This application also provides a vehicle, which can be a commercial vehicle, an electric vehicle, or other automobile with a driver's cab. The vehicle may include a driver's cab and a head-up display (HUD) 00 installed within the driver's cab. The HUD 00 may be the HUD described in the above embodiments.

[0091] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
