[0040] This application provides a vehicle-mounted projection device, which is applied to vehicles. Figure 1 and Figure 2 The vehicle-mounted projection device 1 includes a housing 10 , a projection module 30 and a frame 20 .

[0041] The present application also provides a vehicle, see Figures 3 to 8 The vehicle includes a vehicle body 2 and a vehicle-mounted projection device 1 according to any one embodiment of the present application, and the vehicle-mounted projection device 1 is detachably arranged on the vehicle body 2.

[0042] It should be noted that after the vehicle adopts the on-vehicle projection device 1 of any embodiment of the present application, the vehicle has all the advantages of the on-vehicle projection device 1, and its specific advantages will be described in detail below.

[0043] The specific type of the vehicle is not limited. Exemplarily, the vehicle can be a sedan, an SUV, an off-road vehicle, a commercial vehicle, etc.

[0044] The opposite ends of the housing 10 in the first direction are respectively a first end 101 and a second end 102. The housing 10 is provided with an installation cavity, and one side of the installation cavity is open and forms a first opening, and the first opening is located at the first end 101.

[0045] Here, that is, the first opening penetrates the end wall of the first end 101 of the housing 10.

[0046] Exemplarily, the first direction is Figure 1 the direction shown by L1 in

[0047] The housing 10 plays a protective role for the projection module 30. And, it is convenient to set a connection structure (such as the frame 20) on the housing 10. In this way, it is convenient to mount the housing 10 on the vehicle body 2 or other parts of the vehicle, so as to support the projection module 30 for projection.

[0048] The shape of the housing 10 is not limited. For example, it can be a columnar structure, and the columnar structure can be a cylindrical structure, a prismatic structure, etc.

[0049] At least part of the projection module 30 is disposed in the installation cavity. The projection module 30 has an emission surface 30a and a projection light beam, and the projection light beam is emitted starting from the emission surface 30a.

[0050] The projection module 30 is used to display the parsed data on the screen, such as playing videos and displaying pictures. It is transmitted to the HDMI in chip of the DLP through the HDMI out interface, the signal is converted into an RGB signal for DLP decoding, and then transmitted to the DMD to project the image.

[0051] The emission surface 30a refers to the optical surface when the projection light beam leaves the projection module 30.

[0052] In some embodiments, the emission surface 30a is located outside the accommodation cavity. In this way, the housing 10 will not affect the emission of the projection light beam. Therefore, the projection module 30 can project without being taken out of the accommodation cavity.

[0053] In other embodiments, the emission surface 30a can also be located inside the accommodation cavity. At this time, the projection light beam passes through the first opening. In this way, the housing 10 will not affect the emission of the projection light beam either. Therefore, the projection module 30 can project without being taken out of the accommodation cavity.

[0054] In some embodiments, the in-vehicle projection device 1 further includes a lens module, which is used to assist in adjusting the projection ratio of the projection module 30.

[0055] In some embodiments, the in-vehicle projection device 1 further includes a projection module driver, which is used to decode, decompress and process the received data, and restore it to the original media data.

[0056] In some embodiments, the in-vehicle projection device 1 further includes a projection module heat dissipation, which is used to dissipate heat from the projection module 30.

[0057] In some embodiments, the in-vehicle projection device 1 further includes a distance sensor, which is used to focus the projection screen and correct the screen rectangle.

[0058] In some embodiments, the in-vehicle projection device 1 further includes a wireless communication module. Based on the Wi-Fi protocol, the wireless communication module receives data sent from electronic devices such as a vehicle head unit, a mobile phone, or a tablet computer.

[0059] The frame 20 is connected to the housing 10. The frame 20 is provided with a first connection portion 22a, and the first connection portion 22a is used for detachably connecting to the vehicle.

[0060] Specifically, a second connection portion is provided on the vehicle body 2, and the first connection portion 22a and the second connection portion are detachably connected.

[0061] When the in-vehicle projection device 1 is connected to the second connection portion through the first connection portion 22a, the in-vehicle projection device 1 meets the scenario of being used in the vehicle.

[0062] Exemplarily, please refer to Figure 3 and Figure 6 , the vehicle body 2 has a passenger compartment and a driver's cab. The second connection portion is provided at the top of the passenger compartment or the driver's cab, and the first connection portion 22a is detachably connected to the second connection portion. In this way, the in-vehicle projection device 1 can be used in a relatively private space inside the vehicle.

[0063] Exemplarily, please refer to Figure 7 and Figure 8 , the vehicle body 2 includes a front grille 205 and a cover 206. The front grille 205 is provided with a placement compartment 205a. The front side of the placement compartment 205a is open and forms a second opening. The in-vehicle projection device 1 is arranged in the placement compartment 205a, and the projection light beam passes through the second opening. The cover 206 is arranged on the front grille 205 and selectively opens or closes the second opening.

[0064] It can be understood that when the cover 206 opens the second opening, the projection light beam can be emitted through the second opening, thereby realizing projection. In this way, the use scenario of projecting in front of the vehicle can be satisfied.

[0065] It should be noted that the vehicle body 2 includes a first power supply connector 207. One end of the first power supply connector 207 extends into the placement compartment 205a. A first power connection port 24 is provided on the frame 20, and the first power connection port 24 is electrically connected to the projection module 30.

[0066] The type of the first power connection port 24 is not limited. Exemplarily, it can be a spring pin.

[0067] The type of the first power supply connector 207 is not limited. Exemplarily, it can be a spring pin socket.

[0068] When the vehicle-mounted projection device 1 is disposed in the placement compartment 205a, the first power connection port 24 is electrically connected to the first power supply connector 207. Therefore, it is convenient for the projection module 30 to obtain power. In this embodiment, wiring can be pre-completed on the vehicle, and the user does not need to separately connect power to the projection module 30 in the placement compartment 205a. Therefore, it is convenient for the user to use.

[0069] In some embodiments, the vehicle body 2 further includes an opening member 208 for opening the cover 206. The specific type of the opening member 208 is not limited. Exemplarily, the opening member 208 is a push-button electronic lock controlled by the vehicle controller. The placement compartment 205a provides a storage space for the vehicle-mounted projection device 1. When it is necessary to take out the vehicle-mounted projection device 1 or project in front of the vehicle, the vehicle controller sends an unlocking signal to the push-button electronic lock for unlocking. Further, the cover 206 can automatically pop open, or the cover 206 can be opened by pressing the cover 206 again.

[0070] By separating the first connecting portion 22a and the second connecting portion, the vehicle-mounted projection device 1 can be removed from the vehicle body 2, so that it can be used in an open area outside the vehicle or at a place far away from the vehicle.

[0071] In the vehicle-mounted projection device 1 according to the embodiment of the present application, at least a part of the projection module 30 is disposed in the accommodation cavity of the housing 10. The housing 10 and the frame 20 can provide an installation position for the projection module 30 and facilitate the projection module 30 to be suspended or supported at a special position for use. Moreover, the emission surface 30a is located outside the installation cavity, or the projection beam passes through the first opening; in this way, even if the projection module 30 is not taken out of the accommodation cavity, the housing 10 will not affect or interfere with the projection of the projection module 30. Then, the detachable connection with the vehicle is realized through the first connecting portion 22a on the frame 20. The vehicle-mounted projection device 1 can be connected to a corresponding position on the vehicle for projection, meeting the use scenario of projecting through the vehicle; the vehicle-mounted projection device 1 can also be removed from the vehicle and used in an open area outside the vehicle or at a place far away from the vehicle. Thus, the use scenario of the vehicle-mounted projection device 1 can be broadened, which is beneficial to meeting more use requirements of users.

[0072] In some embodiments, refer to Figure 1 and Figure 2 , the frame 20 includes a connecting arm 21 and two cantilever arms 22. The two cantilever arms 22 are respectively arranged on opposite sides of the housing 10 along the second direction, and the second direction intersects with the first direction; one end of any one of the cantilever arms 22 is rotatably arranged on the housing 10 with the second direction as the axis, and the other end is connected to the connecting arm 21. The cantilever arm 22 is provided with a first connecting portion 22a.

[0073] Exemplarily, the second direction is Figure 1 the direction shown by L2 in

[0074] In this way, the housing 10 and the projection module 30 can be fixedly connected, and the housing 10 and the projection module 30 are carried on the frame 20 as a whole. When it is necessary to change the emission angle of the projection beam of the projection module 30, it can be achieved by operating the rotation of the cantilever arm 22 relative to the housing 10. In this way, the operation is relatively simple and convenient for the user to use.

[0075] In addition, when it is necessary to store the vehicle-mounted projection device 1, the position of the frame 20 on the housing 10 can be changed by rotating the cantilever arm 22. For example, when the vehicle-mounted projection device 1 needs to be stored in the placement compartment 205a, by changing the angle of the frame 20, the size of the vehicle-mounted projection device 1 in certain specific directions can be changed, facilitating the placement of the vehicle-mounted projection device 1 into the placement compartment 205a for storage.

[0076] In some embodiments, refer to Figure 1 and Figure 2 , a receiving groove 10a is provided at the second end 102 of the housing 10. The connecting arm 21 can rotate to the second end 102 of the housing 10, and at least part of the connecting arm 21 is located in the receiving groove 10a.

[0077] In this way, when the connecting arm 21 rotates to the second end 102 of the housing 10, a certain size of the connecting arm 21 is accommodated by the receiving groove 10a, which is beneficial to reducing the size of the vehicle-mounted projection device 1 in the first direction and facilitating the placement of the vehicle-mounted projection device 1 into the placement compartment 205a for storage.

[0078] In some embodiments, refer to Figure 1 and Figure 2 , the frame 20 further includes two support arms 23. The connecting arm 21 is a bar-shaped structure, and the two support arms 23 are respectively arranged on opposite sides in the width direction of the connecting arm 21, and one end of any one of the support arms 23 is rotatably arranged on the connecting arm 21 with the thickness direction of the connecting arm 21 as the axis.

[0079] In this way, when the vehicle-mounted projection device 1 is placed on a bearing surface such as the ground for use, the two support arms 23 can be unfolded. The frame body 20 is supported on the bearing surface through the connecting arm 21 in the length direction of the connecting arm 21, and in the width direction of the connecting arm 21, it is supported on the bearing surface through the two support arms 23. Therefore, the bearing surface can support the frame body 20 in multiple directions, which is beneficial to improving the stability of the vehicle-mounted projection device 1 on the bearing surface.

[0080] When the vehicle-mounted projection device 1 is used in other scenarios other than being placed on the bearing surface, the two support arms 23 can be retracted. In this way, it is beneficial to control the size of the frame body 20 in the width direction of the connecting arm 21, and the vehicle-mounted projection device 1 is convenient for storage or the frame body 20 is convenient for connecting with other components.

[0081] In some embodiments, avoidance areas are provided on both sides in the width direction of the connecting arm 21, and the support arms 23 are located in the avoidance areas in the retracted state. In this way, it is beneficial to further control the size of the frame body 20 in the width direction of the connecting arm 21.

[0082] In some embodiments, the rotatable connection points of the two support arms 23 on the connecting arm 21 are respectively the first rotatable connection point 211 and the second rotatable connection point 212. The first rotatable connection point 211 is close to one end in the length direction of the connecting arm 21, and the second rotatable connection point 212 is close to the other end in the length direction of the connecting arm 21.

[0083] It should be noted that the first rotatable connection point 211 is closer to one end of the connecting arm 21 than the other end of the connecting arm 21, and the second rotatable connection point 212 is closer to the other end of the connecting arm 21 than one end of the connecting arm 21.

[0084] In this way, when the two support arms 23 are in the unfolded state, the frame body 20 and the bearing surface approximately form a "Z" - shaped support, and the support effect of the "Z" - shaped support is better, which is beneficial to further improving the stability of the vehicle-mounted projection device 1 on the bearing surface.

[0085] In some embodiments, please refer to Figures 3 to 5 , the second connecting portion includes a mounting hole 201 and a clamping protrusion 202. The clamping protrusion 202 is arranged in the mounting hole 201. The first connecting portion 22a is a clamping groove. A part of the frame body 20 extends into the mounting hole 201, and the clamping protrusion 202 and the clamping groove are clamped.

[0086] The vehicle body 2 further includes a second power supply connector 209, and the second power supply connector 209 is arranged in the mounting hole 201. The type of the second power supply connector 209 is not limited. Exemplarily, it can be a spring pin socket.

[0087] After the frame body 20 extends into the installation hole 201, the first power connection port 24 on the frame body 20 is electrically connected to the second power supply connector 209. In this way, the second power supply connector 209 supplies power to the projection module 30 through the first power connection port 24.

[0088] Through the clamping protrusion 202 and the card slot, the stable suspension of the frame body 20 in the installation hole 201 is realized. In this way, the vehicle-mounted projection device 1 can be mounted on the top of the cockpit or the top of the passenger compartment for use.

[0089] It should be noted that the vehicle also includes a curtain. The vehicle body 2 is provided with a trunk and a toolbox. The toolbox is located below the trunk. The curtain can be rolled up in the trunk or the toolbox. One end of the curtain is provided with structures such as metal or hooks, and when the trunk lid is opened, it can be connected to the trunk lid by magnetic attraction or suspension.

[0090] In some embodiments, please refer to Figures 3 to 5 , the second connecting portion further includes an elastic reset member 203. Clamping protrusions 202 are provided at both opposite ends of the card slot. The clamping protrusion 202 is movably connected to the hole wall of the installation hole 201; one of the clamping protrusions 202 is the first clamping structure 2021, and the other clamping protrusion 202 is the second clamping structure 2022. The first clamping structure 2021 and the second clamping structure 2022 are also respectively connected to opposite ends of the elastic reset member 203.

[0091] The specific type of the elastic reset member 203 is not limited. Exemplarily, it can be a tension spring or the like.

[0092] In this way, during the process of the frame body 20 extending into the installation hole 201, the two cantilevers 22 respectively squeeze the first clamping structure 2021 and the second clamping structure 2022, so that the first clamping structure 2021 and the second clamping structure 2022 move away from each other. At this time, the elastic reset member 203 undergoes elastic deformation. When the card slot moves to the position where the clamping protrusion 202 is located, the squeezing effect of the cantilever 22 on the clamping protrusion 202 gradually disappears, and the elastic reset member 203 recovers its elastic deformation, thereby driving the clamping protrusion 202 to gradually snap into the card slot and realizing the clamping with the card slot.

[0093] In this embodiment, the structure for the card slot and the clamping protrusion 202 to achieve clamping is relatively simple. The user only needs to push the frame body 20 into the installation hole 201 to realize the clamping of the clamping protrusion 202 and the card slot. The operation is relatively simple and convenient for the user to use.

[0094] In some embodiments, please refer to Figures 3 to 5, the vehicle body 2 further includes an unlocking assembly 204. The unlocking assembly 204 includes a pressing portion 2041. The pressing portion 2041 is respectively drivingly connected to the first clamping structure 2021 and the second clamping structure 2022. In a state where the pressing portion 2041 is pressed, the first clamping structure 2021 and the second clamping structure 2022 respectively move away from each other.

[0095] In this way, by pressing the pressing portion 2041, it is convenient for the clamping protrusion 202 to disengage from the clamping groove, and the user can take out the frame body 20 from the mounting hole 201, realizing the separation of the vehicle-mounted projection device 1 from the vehicle body 2. Thus, the vehicle-mounted projection device 1 can be moved to other positions for use or storage, without affecting the space at the top of the cockpit or the passenger compartment.

[0096] The separation of the vehicle-mounted projection device 1 from the vehicle body 2 can be achieved by pressing the pressing portion 2041. The disassembly method of the vehicle-mounted projection device 1 is relatively simple, which is convenient for the user to use.

[0097] In some embodiments, please refer to Figures 3 to 5 , the unlocking assembly 204 further includes two transmission portions 2042. The two transmission portions 2042 are respectively connected to the first clamping structure 2021 and the second clamping structure 2022. The transmission portion 2042 is provided with a force-receiving surface 2042a, and the pressing portion 2041 is provided with a force-applying surface 2041a. The force-receiving surface 2042a is in contact with the force-applying surface 2041a, and the force-receiving surface 2042a and the force-applying surface 2041a are respectively inclined with respect to the pressing direction of the pressing portion 2041.

[0098] In this way, when the pressing portion 2041 is pressed, since the force-applying surface 2041a and the force-receiving surface 2042a are inclined with respect to the pressing direction of the pressing portion 2041, the pressing force can be decomposed into a component force perpendicular to the pressing direction. By using this component force, the two transmission portions 2042 move away from each other and push the first clamping structure 2021 and the second clamping structure 2022 to move away from each other, so as to respectively disengage from the clamping groove.

[0099] It can be understood that when the pressing portion 2041 is pressed, the elastic resetting member 203 undergoes elastic deformation. After the pressing portion 2041 is released, the elastic resetting member 203 restores elastic deformation, driving the first clamping structure 2021 and the second clamping structure 2022 to reset.

[0100] In this embodiment, the matching structure of the unlocking assembly 204 is relatively simple and has high reliability, which is beneficial to reducing the risk of the clamping protrusion 202 and the clamping groove being stuck, and is convenient for the user to use.

[0101] In some embodiments, the vehicle further includes a power adapter, and a second power connection port 10b is provided on the housing 10. The second power connection port 10b can be, for example, a Type-C interface, etc., and the power adapter can be, for example, a 220V power adapter.

[0102] In this way, after the in-vehicle projection device 1 is taken out of the vehicle, the 220V power adapter converts 220V alternating current (AC) into 13.5V direct current (DC). One end of the power adapter is connected to the second power connection port 10b, thereby providing the required stable voltage and current for the projection module 30.

[0103] Next, the in-vehicle projection device 1 according to the embodiments of the present application will be further described in detail based on three specific usage scenarios.

[0104] The first usage scenario: using the in-vehicle projection device 1 in the vehicle

[0105] Please refer to Figure 2 , when the vehicle is in a stopped state, the whole vehicle controller sends an unlocking signal to the opening member 208 for unlocking. Press one side of the cover body 206 to open the cover body 206, thereby taking out the in-vehicle projection device 1 from the placement compartment 205a.

[0106] Furthermore, pull the connecting arm 21 out of the accommodation groove 10a from the first end 101 towards the second end 102 and rotate it to the middle position of the housing 10.

[0107] Furthermore, insert the frame body 20 into the mounting hole 201 on the top side inside the vehicle. During this process, the elastic reset member 203 deforms, and the clamping protrusions 202 move towards both sides. When the frame body 20 reaches the predetermined position, the elastic reset member 203 restores its elastic deformation, driving the clamping protrusions 202 to return to the initial position, thereby clamping into the card slots of the frame body 20. At this time, the first power connection port 24 (spring pin) on the in-vehicle projection device 1 is docked with the second power supply connector 209 (spring pin socket) in the mounting hole 201, and the second power supply connector 209 takes power through a wire harness.

[0108] Furthermore, hang the curtain on the ceiling at the rear of the carriage by means of a hook / magnet, and keep the lens of the projection module 30 about 1.2m away from the curtain.

[0112] Further, the projection module 30 drives the received data to be decoded, decompressed and other processed, and restored to the original media data.

[0113] Further, the projection module 30 transmits the parsed data to the HDMI in chip of the DLP through the HDMI out interface, converts the signal into an RGB signal for DLP decoding, and then transmits it to the DMD to project the image.

[0114] Further, the projected image is magnified by the lens module to form a 35-inch picture on the curtain at 1.2 m inside the vehicle.

[0115] Further, adjust the angle of the frame body 20 so that the projection screen is in the middle position of the curtain.

[0116] Further, when the projected image becomes blurred due to the distance between the projection module 30 and the curtain, automatic focus and horizontal correction commands can be sent through the software on electronic devices such as car head units / mobile phones / tablet computers. At this time, parameters such as distance are detected by the distance sensor, and then the image is focused and horizontally corrected through the built-in algorithm in the projection module 30.

[0117] Further, when the projection module 30 needs to be removed from the mounting hole 201, just hold the projection module 30 with one hand, press the pressing part 2041 with the other hand, and then slowly remove the projection module 30.

[0118] The second usage scenario: using the in-vehicle projection device 1 outside the vehicle

The in-vehicle projection device 1 is placed in the placement compartment 205a. At this time, the first power connection port 24 (spring pin) on the frame body 20 is docked with the first power supply connector 207 (spring pin socket) of the placement compartment 205a, and the first power supply connector 207 takes power through the wire harness.

[0120] Further, when the vehicle is in a stopped state, the vehicle control unit sends an unlocking signal to the opening / closing member 208 for unlocking. Press one side of the cover body 206 to open the cover body 206.

[0121] Further, wireless signal connection is established between electronic devices such as car head units / mobile phones / tablet computers and the projection module 30.

[0122] Further, a power-on signal is sent to the projection module 30 through a dedicated software on an electronic device such as a vehicle-mounted computer / mobile phone / tablet computer, and the projection module 30 completes the power-on.

[0123] Further, videos / images on an electronic device such as a vehicle-mounted computer / mobile phone / tablet computer are encoded and compressed by the media data processing module, and then transmitted to the projection module 30 through a wireless signal.

[0124] Further, the projection module 30 drives the received data to be decoded, decompressed and other processed to restore it to the original media data.

[0125] Further, the projection module 30 transmits the parsed data to the HDMI in chip of the DLP through the HDMI out interface, converts the signal into an RGB signal for DLP decoding, and then transmits it to the DMD to project the image.

[0126] Further, the projected image is magnified by the lens module to form a 100-inch picture on a screen / white wall 3m in front of the vehicle.

[0127] Further, when the projected image becomes blurred due to the distance between the projection module 30 and the screen, an autofocus and horizontal correction command can be sent through the software on an electronic device such as a vehicle-mounted computer / mobile phone / tablet computer. At this time, parameters such as distance are detected by the distance sensor, and then the image is focused and horizontally corrected through the built-in algorithm in the projection module 30.

[0128] The third usage scenario: using the vehicle-mounted projection device 1 when leaving the vehicle

[0129] Please refer to Figure 7 and Figure 8 , when the vehicle is in a stopped state, the whole vehicle controller sends an unlocking signal to the opening member 208 for unlocking. Press one side of the cover body 206 to open the cover body 206, so as to take out the vehicle-mounted projection device 1 from the placement compartment 205a.

[0130] Further, the connecting arm 21 is pulled out from the accommodation groove 10a in the direction from the first end 101 to the second end 102 and rotated to the middle position of the housing 10. The support arm 23 is rotated 90°, so that the bottom of the frame body 20 forms a cross or Z-shaped bottom surface.

[0131] Further, the vehicle-mounted projection device 1 is placed on a horizontal plane, and then the 220V power adapter is connected to the projection module 30 through the second power connection port 10b. The other end of the 220V power adapter is plugged into a powered socket. At this time, the projection module 30 is powered by the power adapter.

[0132] Further, an electronic device such as a vehicle-mounted computer / mobile phone / tablet computer is wirelessly connected to the projection module 30.

[0133] Further, a power-on signal is sent to the projection module 30 through dedicated software on an in-vehicle computer / mobile phone / tablet computer or other electronic devices, and the projection module 30 completes power-on.

[0134] Further, videos / images on mobile phones / tablet computers or other electronic devices are encoded and compressed through a media data processing module, and then transmitted to the projector through a wireless signal.

[0135] Further, the projection module 30 drives the received data to be decoded, decompressed and other processed to restore it to the original media data.
