Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted equipment, and in particular to a vehicle-mounted device, a display device and a mobile terminal. Background Art

[0002] As people's demands for the comfort, safety, convenience and other in-vehicle functions of mobile terminals (such as vehicles, ships, airplanes and other means of transport) continue to increase, more and more intelligent, digital and networked devices are integrated into mobile terminals. Taking vehicles as an example, rear LCD screens and rear projection equipment are gradually being widely used in large, medium and small passenger cars, commercial vehicles and engineering vehicles, etc., fully enabling the performance improvement of the cockpit and the improvement of the riding experience.

[0003] At present, the above-mentioned vehicle-mounted device is generally exposed and installed outside the vehicle bracket, resulting in the overall structure occupying a large space, which is not conducive to the use of the space inside the vehicle, and the angle of the vehicle-mounted device cannot be adjusted arbitrarily, and cannot meet the viewing effect required by the passengers.

[0004] Therefore, a feasible solution is urgently needed to integrate the above-mentioned vehicle-mounted device into the vehicle bracket to improve the utilization rate of the vehicle interior space and meet the viewing effect required by the passengers through the adjustable angle of the vehicle-mounted device. Utility Model Content

[0005] The embodiments of the present application provide a vehicle-mounted device, a display device, and a mobile terminal, which can improve the utilization rate of the space in the vehicle and meet the viewing effect required by the passengers.

[0006] In a first aspect, an embodiment of the present application provides a vehicle-mounted device, which is installed in a bracket of a mobile terminal, wherein the bracket includes a first outer surface, a second outer surface and a receiving cavity, and the receiving cavity includes a first side surface and a second side surface arranged opposite to each other; the vehicle-mounted device includes:

[0007] Shell, panel;

[0008] At least a portion of the shell surrounds a cavity, the panel is fixedly connected to the shell, and the panel is used to close the cavity;

[0009] The vehicle-mounted device is rotatably installed in the accommodating cavity, the upper surface of the shell contacts the first side surface, and the lower surface of the shell contacts the second side surface.

[0010] In an embodiment of the present application, a vehicle-mounted device is provided, which relates to the technical field of vehicle-mounted equipment and can be specifically applied to mobile terminals such as vehicles to display content to meet the viewing effect required by passengers while taking into account the utilization rate of the space in the vehicle.

[0011] The vehicle-mounted device is installed in a bracket of a movable terminal, and the bracket includes a accommodating cavity, and the accommodating cavity includes a first side surface and a second side surface that are arranged opposite to each other. The vehicle-mounted device includes a shell and a panel, and at least part of the shell surrounds a cavity, and the cavity can be understood as an optical cavity. The principle of the refraction and reflection characteristics of light is used to form a complex light field by focusing light to different positions. The panel is fixedly connected to the shell, and the panel is used to close the cavity. The vehicle-mounted device can be rotatably installed in the accommodating cavity, and the upper surface of the shell contacts the first side surface, and the lower surface of the shell contacts the second side surface. The contact can be understood as a gap between the shell and the accommodating cavity for rotation, and in the case of considering the tooling error, the value range of the gap can be 2mm-3mm. Optionally, the gap can also be other values, which are adjusted according to different vehicle models.

[0012] Since current vehicle-mounted devices are generally exposed and installed outside the vehicle bracket, the overall structure occupies a large space, which is not conducive to the use of the space inside the vehicle, and the angle of the vehicle-mounted device cannot be adjusted arbitrarily, and cannot meet the viewing effect required by passengers.

[0013] In the embodiment of the present application, the vehicle-mounted device is rotatably installed in the receiving cavity of the bracket, so that the normal rotation of the vehicle-mounted device as a whole can be realized. When the passenger needs to use it, the vehicle-mounted device can be controlled to rotate to a certain angle in the unfolded state to meet the viewing effect required by the passenger. When the passenger does not need to use it, the vehicle-mounted device can be controlled to rotate to the storage state to improve the space utilization rate in the vehicle. In addition, since the upper and lower surfaces of the shell of the vehicle-mounted device are in contact with the side of the receiving cavity of the bracket, no cavity will be generated between the vehicle-mounted device and the bracket when rotating, thereby preventing the hand from being pinched or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of the passengers.

[0014] Optionally, the vehicle-mounted device in the embodiment of the present application can be set in the main driver's instrument panel of the mobile terminal, or in the co-driver's panel of the mobile terminal, or in the rear seat back of the mobile terminal, etc., and the embodiment of the present application does not limit this.

[0015] In a possible implementation, the upper surface of the shell is a convex curved surface, and the lower surface of the shell is a convex curved surface.

[0016] In the implementation mode of the present application, the upper and lower surfaces of the shell of the vehicle-mounted device are both convex arc surfaces, which are conducive to the upper and lower surfaces of the shell contacting the side of the accommodating cavity of the bracket and maintaining the contact state during the rotation process, so that no cavity is generated between the vehicle-mounted device and the bracket, thereby preventing hands from being pinched or foreign objects from falling into the rotation gap, thereby ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0017] In a possible implementation manner, the vehicle-mounted device includes a stowed state and an unfolded state.

[0018] In the implementation mode of the present application, two states of the vehicle-mounted device (storage state and deployment state) are provided. When the passenger needs to use it, the vehicle-mounted device can be controlled to rotate to a certain angle in the deployment state to meet the viewing effect required by the passenger. When the passenger does not need to use it, the vehicle-mounted device can be controlled to rotate to the storage state to improve the space utilization rate in the vehicle.

[0019] In a possible embodiment, in the storage state, the outer surface of the panel is flush with the first outer surface of the bracket, the lower surface of the shell is flush with or conforms to the second outer surface of the bracket, the upper surface of the shell remains in contact with the first side surface, and the lower surface of the shell remains in contact with the second side surface.

[0020] In the embodiment of the present application, when the vehicle-mounted device is in the storage state, the outer surface of the panel is flush with the first outer surface of the bracket, and the lower surface of the shell is flush with or follows the second outer surface of the bracket, so that the structure between the vehicle-mounted device and the bracket can be compact, the space occupied is small, and the space utilization rate is high. In addition, the upper surface of the shell keeps in contact with the first side surface of the accommodating cavity, and the lower surface of the shell keeps in contact with the second side surface of the accommodating cavity, so that no cavity is generated between the vehicle-mounted device and the bracket in the storage state, thereby preventing the hand from being pinched or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0021] In a possible embodiment, in the expanded state, an outer surface of the panel is at an angle to a first outer surface of the bracket, a lower surface of the shell is flush with or conforms to a second outer surface of the bracket, an upper surface of the shell remains in contact with the first side surface, and a lower surface of the shell remains in contact with the second side surface.

[0022] In the embodiment of the present application, when the vehicle-mounted device is in the unfolded state, the outer surface of the panel and the first outer surface of the bracket are at an angle, and the lower surface of the shell is flush with or follows the second outer surface of the bracket, so that the structure between the vehicle-mounted device and the bracket can be compact, occupying a small space, and having a high space utilization rate. In addition, the upper surface of the shell keeps in contact with the first side surface of the accommodating cavity, and the lower surface of the shell keeps in contact with the second side surface of the accommodating cavity, so that no cavity is generated between the vehicle-mounted device and the bracket in the unfolded state, thereby preventing the hand from being pinched or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0023] In a possible implementation, when the vehicle-mounted device switches between the stored state and the deployed state, the upper surface of the shell remains in contact with the first side surface, and the lower surface of the shell remains in contact with the second side surface.

[0024] In an embodiment of the present application, when the vehicle-mounted device switches between a stowed state and an unfolded state, the upper surface of the shell of the vehicle-mounted device remains in contact with the first side surface of the accommodating cavity, and the lower surface of the shell of the vehicle-mounted device remains in contact with the second side surface of the accommodating cavity. This ensures that no cavity is generated between the vehicle-mounted device and the bracket when the vehicle-mounted device rotates, thereby preventing hands from being pinched or foreign objects from falling into the rotation gap, thereby ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0025] In a possible implementation manner, a rotation angle range of the vehicle-mounted device from the storage state to the deployment state is a, and a satisfies the following condition: 0°<a≤32°.

[0026] In the implementation manner of the present application, the rotation angle range of the vehicle-mounted device from the storage state to the unfolded state is 0° to 32°, which can not only meet the viewing needs of passengers at various perspectives, but also achieve a compact structure between the vehicle-mounted device and the bracket, small space occupation and high space utilization.

[0027] Optionally, the value range of a mentioned above may also be other values, which is not limited in the embodiment of the present application. For example, it may be 16°<a≤28°, as long as the passenger viewing range of the optical design is met.

[0028] In a possible implementation manner, the lower surface of the shell is composed of two or more consecutive arc surfaces with different curvature radii.

[0029] In the implementation mode of the present application, the lower surface of the shell is composed of two or more continuous segments of arc surfaces with different radii of curvature. It can be understood that the arc length and curvature corresponding to the arc surfaces with different radii of curvature are designed according to the space size of the accommodating cavity of the bracket and the curvature of the second outer surface of the bracket. The specific design value is not limited in the implementation mode of the present application. By forming the lower surface of the shell with two or more continuous segments of arc surfaces with different radii of curvature, the lower surface of the shell can be flush with or follow the second outer surface of the bracket, thereby achieving a compact structure between the vehicle-mounted device and the bracket, small occupied space, and high space utilization. It is also possible to achieve that the lower surface of the shell remains in contact with the second side of the accommodating cavity, so that no cavity is generated between the vehicle-mounted device and the bracket, preventing pinching of hands or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0030] In a possible implementation manner, a curvature radius corresponding to the upper surface of the shell is a first value.

[0031] In the embodiment of the present application, the upper surface of the shell is composed of a section of curved surfaces with the same radius of curvature. It can be understood that the radius of curvature corresponding to the upper surface of the shell remains unchanged (being the first value). The arc length and curvature corresponding to the curved surface with the same radius of curvature are designed according to the space size of the accommodating cavity of the bracket and the curvature of the first outer surface of the bracket. The specific design value is not limited in the embodiment of the present application. By using the upper surface of the shell composed of a section of curved surfaces with the same radius of curvature, it is possible to achieve that the upper surface of the shell is flush with the first outer surface of the bracket, thereby achieving a compact structure between the vehicle-mounted device and the bracket, small occupied space, and high space utilization. It is also possible to achieve that the upper surface of the shell remains in contact with the first side of the accommodating cavity, so that no cavity is generated between the vehicle-mounted device and the bracket, preventing pinching of hands or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0032] In a possible implementation manner, the vehicle-mounted device further includes a motor;

[0033] The rotating shaft of the motor is fixedly connected to one end of the housing, and the driven rotating shaft is fixedly connected to the other end of the housing;

[0034] The motor drives the housing to rotate, thereby realizing the rotation of the vehicle-mounted device.

[0035] In the implementation mode of the present application, the vehicle-mounted device further includes a motor, the shaft of the motor drives the housing to rotate, and the housing drives the panel to rotate, so that the normal rotation of the vehicle-mounted device as a whole can be achieved. When the passenger needs to use it, the vehicle-mounted device can be controlled to rotate to a certain angle in the unfolded state to meet the viewing effect required by the passenger. When the passenger does not need to use it, the vehicle-mounted device can be controlled to rotate to the storage state to improve the space utilization rate in the vehicle.

[0036] In a possible implementation manner, the vehicle-mounted device further includes the bracket;

[0037] The motor and the housing are fixedly connected to the bracket.

[0038] In the implementation manner of the present application, the vehicle-mounted device further includes a bracket, and the motor and the housing are fixedly connected to the bracket. Optionally, the motor and the bracket can be fixed by setting a silicone pad and screws, which can reduce resonance and noise. Optionally, the motor and the bracket can also be rigidly fixed by setting screws, which can reduce deformation during vibration, and the embodiment of the present application does not limit this.

[0039] In a second aspect, an embodiment of the present application provides a display device, which includes an image generating unit and the vehicle-mounted device described in the first aspect and any possible implementation manner; at least a portion of the housing in the vehicle-mounted device surrounds a cavity;

[0040] The image generating unit is located in the cavity and is used to generate a light beam. The light beam is transmitted through the cavity and a panel in the vehicle-mounted device to an object space outside the display device to generate a virtual image visible to human eyes.

[0041] In a possible implementation, the display device further includes an optical element, which is disposed in the cavity and is used to process the light beam.

[0042] In a possible implementation, the display device further includes a speaker, which is disposed in the cavity and is used to generate sound waves.

[0043] Optionally, sound waves may pass through the cavity and a panel in the vehicle-mounted device.

[0058] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0064] See also Figure 1 , Figure 1 A schematic diagram of an application scenario of a mobile terminal provided in an embodiment of the present application.

[0065] like Figure 1 As shown, the mobile terminal 1000 in the embodiment of the present application can be a known means of transportation such as a car, an airplane, a ship, or a new means of transportation that will appear in the future. The car can be an electric car, a fuel car, or a hybrid car, for example, a pure electric car, an extended-range electric car, a hybrid electric car, a fuel cell car, a new energy car, etc., and the present application does not make specific limitations on this.

[0066] The mobile terminal 1000 includes a cabin 200 and seats installed in the cabin 200. The seats include a first seat 300 and a second seat 500, which are used for passengers to sit. In the embodiment of the present application, the first seat 300 is a front seat arranged in the cabin 200. The second seat 500 is a rear seat arranged behind the first seat 300, which is used for passengers to sit. In other embodiments of the present application, the first seat 300 may not be a front seat.

[0067] The first seat 300 includes a seat body 301 and a vehicle-mounted device 10 installed on the seat body 301, which is used to display content to meet the viewing needs of the passengers on the second seat 500. It can be understood that the vehicle-mounted device 10 can also be installed at the co-pilot position of the mobile terminal 1000 (such as Figure 1 As shown), that is, it is installed on the instrument panel (IP) of the mobile terminal to display content to meet the viewing needs of the passengers on the first seat 300, and the embodiment of the present application does not limit this.

[0068] See also Figure 2A and Figure 2B , Figure 2A A schematic diagram of the structure of a vehicle-mounted device provided in an embodiment of the present application is shown in FIG. Figure 2B A schematic diagram of an imaging principle provided in an embodiment of the present application may be Figure 2A Schematic diagram of the imaging principle of the vehicle-mounted device shown.

[0069] like Figure 2A and Figure 2B As shown in the figure, the core optical system of the vehicle-mounted device is composed of an image source screen, a glass window and a reflector, and its characteristic is the display of a magnified virtual image at a distance. Among them, the relative position and angle of the image source screen and the reflector in the display system can be fine-tuned to adapt to different structural spaces. The image seen by the passenger is a virtual image that is magnified by the light emitted by the image source screen and reflected by the glass window and the reflector. The image surface is not on the outer surface of the glass window, but is located a certain distance behind the light field screen. Only in the cone area surrounded by the image light can the passenger's eyes see the complete image. If the human eye deviates from the viewing area, only part of the image can be seen or the image cannot be seen at all. The display has a peep-proof effect on all sides and will not interfere with the driver. Due to the display principle of this system, a cavity of a certain thickness is required to accommodate the internal optical components, so it cannot be simply arranged on the IP surface like a flat-panel display.

[0070] As described in the background technology section, currently the above-mentioned vehicle-mounted devices are generally exposed outside the vehicle bracket, such as being exposed on the backrest of the front seat, or exposed on other locations in the mobile terminal such as the IP station, resulting in the overall structure occupying a large space, which is not conducive to the use of the space inside the vehicle, and the angle of the vehicle-mounted device cannot be adjusted arbitrarily, and cannot meet the viewing effect required by the passengers.

[0071] Therefore, a feasible solution is urgently needed to improve the utilization rate of the space in the car and meet the viewing effect required by the passengers through the adjustable angle of the vehicle-mounted device.

[0072] In view of this, the present application provides a vehicle-mounted device, a display device and a movable terminal, which relate to the field of vehicle-mounted device technology, and can be specifically applied to movable terminals such as vehicles to display content to meet the viewing effects required by passengers while taking into account the utilization rate of the space in the vehicle.

[0073] The vehicle-mounted device, display equipment and mobile terminal provided in this application will be described below with reference to the accompanying drawings.

[0074] See also Figures 3 to 8 , showing a relevant schematic diagram of the vehicle-mounted device provided in an embodiment of the present application.

Figure 4 A schematic diagram of the structure of a vehicle-mounted device provided in an embodiment of the present application is shown. Figure 5 A schematic structural diagram of a vehicle-mounted device provided in an embodiment of the present application is shown.

[0076] Understandable, Figure 4 FIG. 1 shows a schematic diagram of the structure of the vehicle-mounted device in the stowed state. Figure 3 It is shown that Figure 4 A schematic cross-sectional view of the vehicle-mounted device shown, Figure 5 It is shown that Figure 4 The vehicle-mounted device shown is along Figure 3 Schematic diagram of the structure after cross-section cutting is shown.

Figure 7 A schematic diagram of the structure of a vehicle-mounted device provided in an embodiment of the present application is shown. Figure 8 A schematic structural diagram of a vehicle-mounted device provided in an embodiment of the present application is shown.

[0078] Understandable, Figure 7 FIG. 1 shows a schematic diagram of the structure of the vehicle-mounted device in an unfolded state. Figure 6 It is shown that Figure 7 A schematic cross-sectional view of the vehicle-mounted device shown, Figure 8 It is shown that Figure 7 The vehicle-mounted device shown is along Figure 6 Schematic diagram of the structure after cross-section cutting is shown.

[0079] By the above Figures 3 to 8 It can be seen that the embodiment of the present application provides a vehicle-mounted device, which relates to the field of vehicle-mounted equipment technology. Specifically, it can be applied to mobile terminals such as vehicles to display content to meet the viewing effects required by passengers while taking into account the utilization of the space in the vehicle.

[0080] Specifically, the vehicle-mounted device is installed in a bracket 103 of a mobile terminal. The bracket 103 includes a first outer surface 103a, a second outer surface 103b and a receiving cavity 1031. The receiving cavity 1031 includes a first side surface 1031a and a second side surface 1031b that are oppositely arranged.

[0081] The vehicle-mounted device includes:

[0082] Shell 101 and panel 102 .

[0083] Among them, at least part of the shell 101 surrounds a cavity 104, which can be understood as an optical cavity. Using the principle of refraction and reflection characteristics of light, a complex light field is formed by focusing light to different positions. The panel 102 is fixedly connected to the shell 101, and the panel 102 is used to close the cavity 104.

[0084] The vehicle-mounted device is rotatably installed in the accommodating cavity 1031 , the upper surface 101 a of the housing 101 contacts the first side surface 1031 a , and the lower surface 101 b of the housing 101 contacts the second side surface 1031 b .

[0085] Since the current vehicle-mounted device is generally exposed outside the vehicle bracket 103, the overall structure occupies a large space, which is not conducive to the use of the space inside the vehicle, and the angle of the vehicle-mounted device cannot be adjusted arbitrarily, and the viewing effect required by the passengers cannot be met.

[0086] In the embodiment of the present application, the vehicle-mounted device can be rotatably installed in the accommodating cavity 1031 of the bracket 103, so that the normal rotation of the vehicle-mounted device as a whole can be realized. When the passenger needs to use it, the vehicle-mounted device can be controlled to rotate a certain angle to be in the unfolded state (such as Figure 6 or Figure 7 or Figure 8 As shown), it can meet the viewing effect required by passengers. When the passengers do not need to use it, the vehicle-mounted device can be controlled to rotate in the storage state (as shown in FIG. Figure 3 or Figure 4 or Figure 5As shown in FIG. 1 , the space utilization rate in the vehicle can be improved. In addition, since the upper and lower surfaces (101a, 101b) of the housing 101 of the vehicle-mounted device are in contact with the side surfaces (1031a, 1031b) of the accommodating cavity 1031 of the bracket 103, no cavity will be generated between the vehicle-mounted device and the bracket 103 when the vehicle-mounted device rotates, thereby preventing the hand from being caught or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0087] Optionally, the vehicle-mounted device in the embodiment of the present application can be set in the main driver's instrument panel of the mobile terminal, or in the co-driver's panel of the mobile terminal, or in the rear seat back of the mobile terminal, etc., and the embodiment of the present application does not limit this.

[0088] In a possible embodiment, the upper surface 101 a of the housing 101 is a convex arc surface, and the lower surface 101 b of the housing 101 is a convex arc surface.

[0089] It can be understood that the upper and lower surfaces (101a, 101b) of the shell 101 of the vehicle-mounted device are both convex arc surfaces, which is conducive to the upper and lower surfaces (101a, 101b) of the shell 101 and the side surfaces (1031a, 1031b) of the accommodating cavity 1031 of the bracket 103 to contact and maintain the contact state during the rotation process, so that no cavity is generated between the vehicle-mounted device and the bracket 103, thereby preventing hands from being pinched or foreign objects from falling into the rotation gap, thereby ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0090] In a possible embodiment, the vehicle-mounted device includes a stowed state and an unfolded state.

[0091] Among them, the storage status can be found in Figure 3 , Figure 4 , Figure 5 The vehicle-mounted device shown in the figure can be seen in the unfolded state. Figure 6 , Figure 7 , Figure 8 The vehicle-mounted device shown.

[0092] When passengers need to use it, the vehicle-mounted device can be controlled to rotate to a certain angle to be in an expanded state, thereby satisfying the viewing effect required by passengers. When passengers do not need to use it, the vehicle-mounted device can be controlled to rotate to a stored state, thereby improving the utilization rate of the space in the vehicle.

[0093] In a possible embodiment, in the above-mentioned storage state (such as Figure 3 or Figure 4 or Figure 5As shown), the outer surface of the panel 102 is flush with the first outer surface 103a of the bracket 103, the lower surface 101b of the shell 101 is flush with or follows the second outer surface 103b of the bracket 103, the upper surface 101a of the shell 101 remains in contact with the first side surface 1031a, and the lower surface 101b of the shell 101 remains in contact with the second side surface 1031b.

[0094] It can be understood that when the vehicle-mounted device is in the storage state, the outer surface of the panel 102 is flush with the first outer surface 103a of the bracket 103, and the lower surface 101b of the shell 101 is flush with or follows the second outer surface 103b of the bracket 103, so that the structure between the vehicle-mounted device and the bracket 103 can be compact, the space occupied is small, and the space utilization rate is high.

[0095] Furthermore, the upper surface 101a of the shell 101 remains in contact with the first side surface 1031a of the accommodating cavity 1031, and the lower surface 101b of the shell 101 remains in contact with the second side surface 1031b of the accommodating cavity 1031, so that no cavity is generated between the vehicle-mounted device and the bracket 103 in the stored state, thereby preventing hands from being pinched or foreign objects from falling into the rotation gap, thereby ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0096] In a possible embodiment, in the above-mentioned unfolded state (such as Figure 6 or Figure 7 or Figure 8 As shown), the outer surface of the panel 102 is at an angle to the first outer surface 103a of the bracket 103, the lower surface 101b of the shell 101 is flush with or conforms to the second outer surface 103b of the bracket 103, the upper surface 101a of the shell 101 remains in contact with the first side surface 1031a, and the lower surface 101b of the shell 101 remains in contact with the second side surface 1031b.

[0097] It can be understood that when the vehicle-mounted device is in the unfolded state, there is an angle between the outer surface of the panel 102 and the first outer surface 103a of the bracket 103, and the lower surface 101b of the shell 101 is flush or conforming to the second outer surface 103b of the bracket 103, so that the structure between the vehicle-mounted device and the bracket can be compact, the space occupied is small, and the space utilization rate is high.

[0098] In addition, the upper surface 101a of the shell 101 remains in contact with the first side surface 1031a of the accommodating cavity 1031, and the lower surface 101b of the shell 101 remains in contact with the second side surface 1031b of the accommodating cavity 1031, so that no cavity is generated between the vehicle-mounted device and the bracket 103 in the unfolded state, thereby preventing hands from being pinched or foreign objects from falling into the rotation gap, thereby ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0099] In a possible embodiment, when the vehicle-mounted device switches between the above-mentioned storage state and the unfolded state, the upper surface 101a of the shell 101 remains in contact with the first side surface 1031a, and the lower surface 101b of the shell 101 remains in contact with the second side surface 1031b.

[0100] It can be understood that when the vehicle-mounted device switches between the stowed state and the deployed state, the upper surface 101a of the shell 101 of the vehicle-mounted device remains in contact with the first side surface 1031a of the accommodating cavity 1031, and the lower surface 101b of the shell 101 of the vehicle-mounted device remains in contact with the second side surface 1031b of the accommodating cavity 1031. This can prevent the vehicle-mounted device from generating a cavity between the bracket 103 during rotation, thereby preventing hands from being pinched or foreign objects from falling into the rotation gap, thereby ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0101] In a possible embodiment, the rotation angle range of the vehicle-mounted device from the storage state to the unfolded state is a, and a satisfies the following condition: 0°<a≤32°.

[0102] For details, please refer to Fig. 9 , Fig. 9 A schematic diagram of the rotation of a vehicle-mounted device provided in an embodiment of the present application.

[0103] like Fig. 9 As shown, the rotation angle range of the vehicle-mounted device from the stored state (the vehicle-mounted device shown by the dotted line) to the deployed state (the vehicle-mounted device shown by the solid line) is 0° to 32°, which can not only meet the viewing needs of passengers at various perspectives, but also achieve a compact structure between the vehicle-mounted device and the bracket 103, small space occupation and high space utilization.

[0104] Optionally, the value range of a mentioned above may also be other values, which is not limited in the embodiment of the present application. For example, it may be 16°<a≤28°, as long as the passenger viewing range of the optical design is met.

[0105] In a possible embodiment, the lower surface 101 b of the housing 101 is composed of two or more consecutive arc surfaces with different curvature radii.

[0106] It can be understood that the arc length and radian corresponding to the arc surface with different curvature radii are designed according to the space size of the accommodating cavity 1031 of the bracket 103 and the radian of the second outer surface 103b of the bracket 103, and the specific design value is not limited in the embodiment of this application.

[0107] By forming the lower surface 101b of the housing 101 with two or more continuous arc surfaces of different curvature radii, the lower surface 101b of the housing 101 can be flush with or follow the second outer surface 103b of the bracket 103, thereby achieving a compact structure between the vehicle-mounted device and the bracket 103, small space occupation, and high space utilization. The lower surface 101b of the housing 101 can also be kept in contact with the second side surface 1031b of the accommodating cavity 1031, so that no cavity is generated between the vehicle-mounted device and the bracket 103, preventing hands from being pinched or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0108] In a possible embodiment, the curvature radius corresponding to the upper surface 101 a of the housing 101 is a first value.

[0109] It is understandable that the radius of curvature corresponding to the upper surface 101a of the housing 101 remains unchanged (being the first value). The arc length and radian corresponding to the arc surface with the same radius of curvature are designed according to the space size of the accommodating cavity 1031 of the bracket 103 and the radian of the first outer surface 103a of the bracket 103, and the specific design values ​​are not limited in the embodiments of the present application.

[0110] The upper surface 101a of the housing 101 is composed of an arc surface with the same radius of curvature, so that the upper surface 101a of the housing 101 can be flush with the first outer surface 103a of the bracket 103, thereby achieving a compact structure between the vehicle-mounted device and the bracket 103, small space occupation, and high space utilization. It is also possible to achieve that the upper surface 101a of the housing 101 is kept in contact with the first side surface 1031a of the accommodating cavity 1031, so that no cavity is generated between the vehicle-mounted device and the bracket 103, preventing hands from being pinched or foreign objects from falling into the rotation gap, and ensuring the normal rotation of the vehicle-mounted device and the safety of passengers.

[0111] In a possible embodiment, the vehicle-mounted device further includes a motor 105 .

[0112] The rotating shaft of the motor 105 is fixedly connected to one end of the housing 101 , and the driven rotating shaft is fixedly connected to the other end of the housing 101 .

[0113] The motor 105 drives the housing 101 to rotate, and the housing 101 drives the panel 102 to rotate, so that the normal rotation of the entire vehicle-mounted device can be achieved.

[0114] It is understandable that when the passenger needs to use it, the vehicle-mounted device is controlled to rotate to a certain angle to be in the unfolded state (such as Figure 6 or Figure 7 or Figure 8 As shown), it can meet the viewing effect required by passengers. When the passengers do not need to use it, the vehicle-mounted device can be controlled to rotate in the storage state (as shown in FIG. Figure 3 or Figure 4 or Figure 5 As shown), it can improve the utilization of the space inside the car.

[0115] For details, please refer to Fig.10 , Fig.10 A schematic diagram of the structure of a vehicle-mounted device provided in an embodiment of the present application.

[0116] like Fig.10 As shown, the vehicle-mounted device is composed of an optical module and a transmission system, which are connected by a rotating shaft and then fixed to the vehicle body frame by a bracket structure. The optical module is driven by the transmission system and can rotate around a fixed axis.

[0117] In a possible embodiment, the vehicle-mounted device further includes a bracket 103 .

[0118] The motor 105 and the housing 101 are fixedly connected to the bracket 103 .

[0119] Optionally, the motor 105 and the bracket 103 can be fixed by setting a silicone pad and screws, which can reduce resonance and noise.

[0120] Optionally, the motor 105 and the bracket 103 may be rigidly fixed by setting screws, which can reduce deformation during vibration, and the embodiment of the present application does not limit this.

[0121] Accordingly, the above Figures 3 to 10 It can be seen that the embodiment of the present application also provides a display device, which relates to the field of vehicle-mounted equipment technology, and can be specifically applied to mobile terminals such as vehicles to display content to meet the viewing effects required by passengers while taking into account the utilization of the space in the vehicle.

[0122] Specifically, the display device includes an image generating unit and a Figures 3 to 10 The vehicle-mounted device shown in any one of the items.

[0123] At least a portion of the shell in the vehicle-mounted device surrounds and forms a cavity.

[0124] The image generating unit is located in the cavity and is used to generate a light beam, which is transmitted through the cavity and the panel in the vehicle-mounted device to the object space outside the display device to generate a virtual image visible to the human eye.

[0125] In a possible implementation, the display device further includes an optical element, which is disposed in the cavity and is used to process the light beam.

[0126] In a possible implementation, the display device further includes a speaker, which is disposed in the cavity and is used to generate sound waves.

[0127] Optionally, sound waves may pass through the cavity and a panel in the onboard device.

[0128] The present application also provides a mobile terminal, which includes the above-mentioned Figures 3 to 10 The vehicle-mounted device shown in any one of the items, or the above-mentioned display device.

[0129] It should be understood that the mobile terminals involved in this application may include intelligent terminals or transportation tools such as vehicles, robots, drones, ships, and ships. Among them, the vehicle is a vehicle in a broad sense, which can be a transportation tool (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), an agricultural equipment (such as a mower, a harvester, etc.), etc. For another example, the robot can be an intelligent handling robot (automated guided vehicle, AGV), a walking conversation robot, a service robot, and other robots.

[0130] It should be understood that the above Figures 3 to 10 The embodiments shown are merely exemplary descriptions of several possible vehicle-mounted devices, display devices, and mobile terminals provided by the present application, and should not be construed as limiting the present application. Figures 3 to 10 New embodiments obtained by reasonable deformation, supplementation or combination of the illustrated embodiments all fall within the protection scope of this application.

[0131] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
