[0027] In order to make those skilled in the art better understand the present application scheme, the technical scheme in the present application embodiment will be clearly and completely described below in conjunction with the drawings in the present application embodiment. Obviously, the described embodiment is only a part of the present application embodiment, rather than all the embodiments. The components of the present application embodiment usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiment of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0029] With the continuous development of automobiles, the functions of in-vehicle systems are gradually enriched, and passengers' demand for watching movies is also increasing. Although some in-vehicle projection systems have been developed, the projection positions of existing in-vehicle projection systems are relatively fixed, which makes it difficult to adapt to passengers' viewing needs in different directions, and the utilization rate of in-vehicle projectors is low.

[0030] Therefore, in the embodiments of the present application, a connection device, a vehicle-mounted projection system and a vehicle are provided to solve or partially solve the above-mentioned problems.

[0031] See also Figure 1 , which shows a structural schematic diagram of a connecting device 100 provided in an embodiment of the present application, which is applied to a vehicle-mounted projection system. The connecting device 100 includes: a fixing seat 1, a supporting component 2 and a first component 3.

[0032] The first component 3 has a first base 31 and a first rotating shaft 32 . The first rotating shaft 32 is rotatably connected to the first base 31 . The first rotating shaft 32 is used to rotate around the axis of the first rotating shaft 32 .

[0033] The fixing seat 1 has a first end 11 and a second end 12 which are arranged opposite to each other. The first end 11 is used to be connected to a first mounting portion on the roof. The second end 12 is connected to the first base 31 through the supporting assembly 2. The first rotating shaft 32 is provided with a mounting member 41 which is used to mount the projector 4 of the vehicle-mounted projection system.

[0034] It should be noted that the fixing seat 1 is used to be fixedly installed on the roof. Specifically, the first end 11 of the fixing seat 1 is connected to the first mounting portion of the roof, and the second end 12 of the fixing seat 1 is connected to the first base 31 through the supporting assembly 2. The first base 31 is rotatably connected to the first rotating shaft 32. The first rotating shaft 32 can rotate around the axis of the first rotating shaft 32, and the first rotating shaft 32 is provided with a mounting member 41, which is used to connect to the projector of the vehicle-mounted projection system through the mounting member 41.

[0035] In one implementation scenario, when the fixing seat 1 is fixed on the roof and the projector is fixed on the first rotating shaft 32 through the mounting member 41, the rotation of the first rotating shaft 32 can rotate the projector, so that the projector can be projected in multiple directions, that is, "one machine with multiple projections", avoiding the projector projecting in a fixed direction, and meeting the passengers' needs for multi-directional viewing.

[0036] Furthermore, the position of the projector can be fixed by a locking mechanism, which is arranged on the first base 31 and has two states: locked and unlocked. The locking mechanism can be switched between the locked state and the unlocked state by manually controlling the locking mechanism, or by controlling the locking mechanism to switch between the locked state and the unlocked state by a control module.

[0037] For example, when the projector is not in operation, the locking mechanism is in a locked state to fix the projector. When the projection direction of the projector needs to be changed, the locking mechanism is controlled to be in an unlocked state, and the projection direction of the projector can be adjusted by rotating the first rotating shaft 32. After the projection direction of the projector is adjusted, the locking mechanism is controlled to be in a locked state to fix the projector.

[0038] It should be noted that Figure 1 This is a schematic diagram of a connection device provided for this embodiment. The shapes and sizes of the components are not limited and can be adjusted according to actual needs.

[0039] For further information, see Figure 1 The support assembly 2 includes a second assembly 21 , a first support member 22 and a second support member 23 .

[0040] The second component 21 has a second base 211 and a second rotating shaft 212 . The second base 211 is rotatably connected to the second rotating shaft 212 . The second rotating shaft 212 is used to rotate around the axis of the second rotating shaft 212 .

[0041] The second end portion 12 of the fixing seat 1 is used for fixedly connecting with the second base 211 through the first supporting member 22 , and the second rotating shaft 212 is fixedly connected with the first base 31 through the second supporting member 23 .

[0042] As an implementation mode, the first end 11 of the fixing seat 1 is connected to the first mounting portion of the roof, the second end 12 of the fixing seat 1 is connected to the second base 211 through the first support member 22, the second base 211 is rotatably connected to the second rotating shaft 212, the second rotating shaft 212 is connected to the first base 31 through the second support rod, the first base 31 is rotatably connected to the first rotating shaft 32, and the first rotating shaft 32 is used to connect to the projector through the mounting member 41. Among them, rotating the first rotating shaft 32 can change the projection direction of the projector, and rotating the second rotating shaft 212 can also change the rotation direction of the projector. The present application can adjust the projection direction of the projector through the first rotating shaft 32 and the second rotating shaft 212, thereby realizing that the projection orientation of the projector can be adjusted, thereby achieving the effect of one machine with multiple projections, and improving the utilization rate of the vehicle-mounted projector.

[0043] Furthermore, the connection device 100 also includes: a control module.

[0044] The first component 3 further includes a first driving member, which is disposed on the first base 31 , and a transmission member of the first driving member is connected to the first rotating shaft 32 .

[0045] The second assembly 21 further includes a second driving member, which is disposed on the second base 211 , and a transmission member of the second driving member is connected to the second rotating shaft 212 .

[0046] The control module is connected to the first driving member, and is used to drive the first rotating shaft 32 to rotate around the axis of the first rotating shaft 32 .

[0047] The control module is connected to the second driving member, and is used to drive the second rotating shaft 212 to rotate around the axis of the second rotating shaft 212 .

[0048] Exemplarily, the control module controls the first driving member to operate, drives the first rotating member to rotate, and changes the projection direction of the projector.

[0049] In another exemplary embodiment, the control module controls the second driving member to operate, thereby driving the second rotating member to rotate, thereby changing the projection direction of the projector.

[0050] In another exemplary embodiment, the control module controls the first driving member and the second driving member to operate, drives the first rotating shaft and the second rotating member to rotate, and changes the projection direction of the projector.

[0051] Furthermore, a first switch is provided, which is electrically connected to the first drive member, and the first switch can be manually operated to control the rotation of the first rotating shaft, thereby controlling the rotation of the projector. A second switch is provided, which is electrically connected to the second drive member, and the second switch can be manually operated to control the rotation of the second rotating shaft, thereby controlling the rotation of the projector.

[0052] See also Figure 2 , which shows a schematic structural diagram of a vehicle-mounted projection system 200 in working state provided by an embodiment of the present application. The vehicle-mounted projection system 200 includes: a projector 4 and the aforementioned connecting device 100.

[0053] The projector 4 is mounted on the mounting member of the connecting device, and the projection direction of the projector 4 is not parallel to the axis of the first rotating shaft.

[0054] It should be noted that the projection direction of the projector is not parallel to the axis of the first rotation shaft. When the first rotation shaft rotates, the projection direction of the projector may change significantly.

[0055] Optionally, the angle between the projection direction of the projector and the axis of the first rotation axis is 90 degrees. When the first rotation axis rotates 90 degrees, the projection direction of the projector also changes by 90 degrees, so that the projection direction of the projector can be adjusted more accurately and quickly.

[0056] Furthermore, the control module is connected to the projector 4 to instruct the projector 4 to work.

[0057] As an implementation mode, the control module is connected with the projector, the first driving member and the second driving member, and can control whether the first driving member, the second driving member and the projector are working or not.

[0058] Furthermore, the projector may be an ultra-short-throw projector with the characteristic of short-distance projection, which can save the spatial distance from the projector to the display screen and reduce the probability of the projection light being blocked to a certain extent in a cabin with relatively limited space.

[0059] For further information, see Figures 2 to 5 The vehicle-mounted projection system 200 further includes: a first display component 5 , which includes a housing 51 , a third driving member, a rotating mechanism and a scroll screen 52 .

[0060] Among them, the shell 51 has a first end face 511 and a second end face 512 that are relatively arranged. The first end face 511 is used to connect with the second mounting part of the roof. The second end face 512 is provided with a storage hole as the entrance and exit of the roll-up screen 52. The roll-up screen 52 is used to receive the light projected by the projector.

[0061] The scroll screen 52 has a fixed end and a movable end 521 that are relatively arranged. The rotating mechanism is connected to the fixed end of the scroll screen 52. The third driving member is arranged in the shell 51 and is connected to the control module and the rotating mechanism. It is used to drive the rotating mechanism to rotate and drive the movable end 521 of the scroll screen 52 to move closer to or away from the shell 51.

[0062] As an implementation mode, the first display component 5 is fixed on the roof. Specifically, the first end surface 511 of the shell 51 of the first display component 5 is connected to the second mounting portion of the roof. The control module is electrically connected to the third driving member. The third driving member is connected to the rotating mechanism. The control module can control the third driving member to drive the rotating mechanism not to rotate, to rotate forward or reverse. When the rotating mechanism rotates forward, the active end 521 of the scroll screen 52 is away from the shell 51. When the rotating mechanism does not rotate, the active end 521 of the scroll screen 52 maintains the current position. When the rotating mechanism reverses, the scroll screen 52 is driven close to the shell 51 to realize the unfolding and folding of the scroll screen 52.

[0063] It should be noted that, viewed from the left side of the vehicle, the first mounting portion is located between the second mounting portion and the sunroof, and the second mounting portion is located on the roof at the second row of the vehicle, and the unfolded surface of the rolling screen 52 is not perpendicular to the longitudinal direction of the vehicle.

[0064] Optionally, the unfolding surface of the roll-up screen 52 is parallel to the lateral direction of the vehicle.

[0065] In an exemplary embodiment, the station where the projector projects onto the scroll screen 52 is the first projection station. When the passenger selects the first projection station, an instruction can be issued to the control module. The control module controls the third drive member to drive the rotating mechanism to rotate, so that the scroll screen 52 is unfolded to a preset position. The control module controls the first drive member and the second drive member to work and adjust the projection direction of the projector so that the scroll screen 52 can basically receive all the light projected by the projector, that is, the projector is adjusted to the first projection station, and then the projector is controlled to start projection, and the passenger can watch the movie.

[0066] It should be noted that the image formed on the scroll screen 52 can be viewed by the passengers in the second row and the row behind it, and the projector can be switched from the non-working position to the first projection position in advance. After the scroll screen 52 is installed to the second mounting part of the roof, the first drive member and the second drive member are adjusted to adjust the projector so that all the light projected by the projector is irradiated onto the scroll screen 52, and the rotation angle of the first rotating shaft and the rotation angle of the second rotating shaft are recorded. When it is necessary to project onto the scroll screen 52, the first drive member and the second drive member can be adjusted according to the recorded data to switch the projector from the non-working position to the first projection position.

[0067] Furthermore, the vehicle-mounted projection system 200 further includes a distance sensor 6 , which is disposed on the housing 51 and connected to the control module, and is used to detect the distance between the movable end 521 of the scroll screen 52 and the housing 51 .

[0068] Furthermore, the projector has a processing module, and the processing module is used to adjust the size of the projection picture.

[0069] In one exemplary embodiment, a passenger can select the extent to which the scroll screen can be unfolded, see Figure 3-Figure 5 For example, if the passenger selects the expansion degree of the scroll screen 52 to be 100%, after receiving the signal, the control module controls the third driving member to rotate forward until the distance sensor 6 detects that the distance data detected by the scroll screen 52 reaches a preset value, and then the third driving member stops rotating. At this time, the processing module adjusts the size of the projection screen according to the expansion degree of the scroll screen to make the projection screen match the scroll screen 52, and then adjusts the first driving member and the second driving member so that the light projected by the projector is basically all irradiated on the scroll screen 52.

[0070] In an exemplary embodiment, the passenger can adjust the degree of expansion of the scroll screen 52 by himself, until the passenger sends a signal to confirm the degree of expansion of the scroll screen 52, the distance sensor 6 detects the distance between the movable end 521 of the scroll screen 52 and the housing 51, obtains distance data, and then transmits the distance data to the processing module of the projector, and the processing module adjusts the size of the projected screen of the projector according to the distance data, so that the size of the screen projected by the projector matches the degree of expansion of the scroll screen 52. The first driving member and the second driving member are adjusted so that the light projected by the projector is basically all irradiated on the scroll screen 52.

[0071] It should be noted that the processing module includes a stored program, which can adjust the size of the projection screen according to the distance data or the expansion degree of the scroll screen.

[0072] For further information, see Figure 6 , which shows a schematic structural diagram of a vehicle-mounted projection system 200 in another working state provided by an embodiment of the present application, wherein the vehicle-mounted projection system 200 further includes: a second display component 7, wherein the second display component 7 is used to be installed on a third installation portion of the roof, and the third installation portion is arranged adjacent to a skylight on the roof.

[0073] The second display component 7 has two states: expanded and retracted. When the second display component 7 is in the expanded state, the second display component 7 covers the sunroof of the vehicle and is used to receive the light projected by the projector 4. When the second display component 7 is in the retracted state, the second display component 7 does not block the sunroof of the vehicle.

[0074] It should be noted that, viewed from the left side of the vehicle, the first mounting portion is located between the second mounting portion and the third mounting portion.

[0075] As an exemplary embodiment, the second display component may be a light-colored sunshade curtain, which can be used to receive the light projected by the projector to form an image.

[0076] In an exemplary embodiment, the skylight is made of a light-colored non-transparent material and can be used to receive light projected by a projector to form an image.

[0077] Furthermore, the vehicle-mounted projection system 200 further includes: a first detection component, a second detection component and a third detection component, and the control module is connected to the first detection component, the second detection component and the third detection component.

[0078] The first detection member is arranged on the first driving member, and is used to detect the rotation angle of the first rotating shaft. The second detection member is arranged on the roof, and is used to detect the state of the second display component. The third detection member is arranged on the second driving member, and is used to detect the rotation angle of the second rotating shaft.

[0079] Optional, see Figure 7 , which shows a simplified structural schematic diagram of the vehicle-mounted projection system 200 provided in an embodiment of the present application. When the projector 4 is in the initial position, the projector 4 is in a non-working state. The position where the projector 4 projects onto the scroll screen is the first projection position. The projection direction of the projector 4 at the first projection position is as follows: Figure 7 The position where the projector 4 projects onto the second display assembly is the second projection position. The projection direction of the projector 4 at the second projection position is as shown in FIG. Figure 7 The position where the projector 4 projects onto the skylight is the third projection position. The projection direction of the projector 4 at the third projection position is as shown in FIG. Figure 7 The direction shown in H3.

[0080] As an implementation mode, the control module receives the first signal and adjusts the projector from the initial position to the first projection position. Specifically, the control module drives the third driving member to unfold the scroll screen, and controls the scroll screen to unfold to a preset position in combination with the distance data detected by the distance sensor. At the same time, the control module controls the first driving member and the second driving member to rotate. When the first detection member detects that the rotation angle of the first rotating shaft is the first preset angle, the first driving member is controlled to stop the rotation of the first rotating shaft. When the third detection member detects that the rotation angle of the second rotating shaft is the second preset angle, the second driving member is controlled to stop the rotation of the second rotating shaft, thereby adjusting the projector from the initial position to the first projection position. At this time, the projector is turned on, and the processing module of the projector adjusts the size of the projected image according to the distance data obtained by the distance sensor, and then projects light to the scroll screen to enable passengers to watch movies through the scroll screen.

[0081] As an implementation mode, the control module receives a second signal and adjusts the projector from the initial position to the second projection position. Specifically, the control module controls the rotation of the first driving member and the second driving member. When the first detection member detects that the rotation angle of the first rotating shaft is the third preset angle, the first driving member is controlled to stop the rotation of the first rotating shaft. When the third detection member detects that the rotation angle of the second rotating shaft is the fourth preset angle, the second driving member is controlled to stop the rotation of the second rotating shaft. At this time, the control module controls the second detection member to detect the state of the second display component. If the state of the second display component is detected to be in the expanded state, it means that it can be projected to the second display component, so that the processing module of the projector adjusts the size of the projection screen according to the first predetermined size, so that the light projected by the projector is basically all irradiated on the second display component, wherein the first predetermined size is the size of the second display component in the expanded state stored in advance.

[0082] If it is detected that the state of the second display component is retracted, it means that projection can be made onto the sunroof, so that the processing module of the projector adjusts the size of the projection screen according to the second predetermined size, so that almost all the light projected by the projector is irradiated onto the sunroof. The second predetermined size is the same as the size of the sunroof saved in advance. The second row passengers and the passengers in the back row can watch the movie in a half-lying position with their heads up. This posture is more suitable for passengers to rest.

[0083] It should be noted that, since the second display assembly is disposed adjacent to the skylight on the roof, the second projection station and the third projection station may be the same or different, and may be selected according to actual conditions.

[0084] As an implementation mode, contact switch A and contact switch B are respectively set on the first component and the second component. When the projector is located at the first projection position, contact switch A is triggered. When the projector is at the second projection position, contact switch B is triggered. Contact switch C is set at the unfolded position of the sunshade. When the sunshade is in the unfolded state, contact switch C is triggered.

[0085] The projector can adapt to the size of the screen required for display at each projection station. Specifically, the screen size corresponding to each projection station can be adjusted to an appropriate size and saved by screen cropping. Then, each screen size is associated with the triggering status of three contact switches through a software program. That is, when contact switch A is triggered, the projector projects a pre-set screen that matches the scroll screen; when contact switch B is triggered and contact switch C is not triggered, the projector projects a pre-set screen that matches the sunroof; when contact switch B and contact switch C are triggered at the same time, the projector projects a pre-set screen that matches the sunshade. This enables the projector to automatically match the size of the screen required for projection at different projection stations, allowing cabin passengers to more conveniently and smoothly watch the screen of the size they want.

[0086] See also Figure 6 to Figure 7 The projector 4 of the present application has multiple projection positions, which can provide passengers with viewing experiences in different directions and improve the utilization rate of the vehicle-mounted projector.

[0087] As an implementation mode, it is also possible to switch between the first projection station, the second projection station and the third projection station. When switching the projection stations, the processing module of the projector can adjust the projection screen size according to the corresponding imageable sizes at different stations, thereby achieving smooth switching between different projection stations.

[0088] For example, the passenger is sitting at first, and the projector can be adjusted to the first projection position, and the passenger can watch the movie by watching the scroll screen in front. When the passenger feels a little tired, he / she half lies on the seat, and the projector can be adjusted to the second projection position or the third projection position at this time, and the passenger can watch the movie more comfortably while half lying on the seat. Therefore, the present application provides more viewing positions for passengers, so that passengers can watch movies more comfortably, and improves the utilization rate of the vehicle-mounted projector.

[0089] As an embodiment, when the vehicle-mounted projection system is installed on the vehicle and the projector is in the first projection position, the angle between the axis of the first rotating shaft and the axis of the second rotating shaft is 90 degrees, the axis of the first rotating shaft is parallel to the horizontal direction and perpendicular to the direction of the roof beam 10, and the axis of the second rotating shaft is parallel to the direction of the roof beam 10.

[0090] As an exemplary example, when it is necessary to switch from the first projection station to the second projection station, the first rotating member can be driven to rotate the first rotating axis 180°, and then the second driving member can be driven to rotate the second rotating axis 90 degrees clockwise at a first viewing angle, thereby realizing the switching from the first projection station to the second projection station, and the first viewing angle is viewed from the left side of the vehicle.

[0091] As an exemplary example, when it is necessary to switch from the second projection station to the first projection station, the second driving member can be driven to rotate the second rotating axis 90 degrees counterclockwise at the first viewing angle, and then the first rotating member can be driven to rotate the first rotating axis 180°, thereby realizing the switching from the second projection station to the first projection station, and the first viewing angle is viewed from the left side of the vehicle.

[0092] Furthermore, the present application proposes a vehicle, comprising: a vehicle body and the aforementioned connecting device.

[0093] The vehicle body has a first mounting portion, and the first mounting portion is used for mounting the fixing seat.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
