Description

Technical Field

[0001] The present application relates to the technical field of projection equipment, and in particular to an adjustment device for projection equipment, a vehicle-mounted projection system and a vehicle. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, in-vehicle entertainment systems have become an important part of modern vehicles. As an emerging in-vehicle entertainment device, projectors can provide passengers with large-screen visual enjoyment and enhance the riding experience. However, in actual application, the installation and use of projectors face some problems and challenges.

[0003] In the related art, the projector is usually fixed at a specific position in the cabin. Due to the existence of assembly tolerance and manufacturing tolerance, it is difficult for a fixedly installed projector to meet the accuracy requirements during the installation process. This fixed installation method not only affects the projection effect, but may also cause the deviation of the projection beam, causing discomfort to the passengers during the viewing process. For this reason, the related art provides a bracket that can adjust the installation angle of the projector. However, these brackets are often complex in structure, bulky in size, and difficult to operate. Therefore, there is an urgent need for a projector angle adjustment structure with a simple structure, small size, and easy operation. Utility Model Content

[0006] The adjustment device for the projection device provided in the present application can provide an installation position for the projection device through the bearing part because a bearing part is provided on the support frame. In addition, an adjustment member is provided on the support portion of the support frame, and an adjustment structure is provided on the adjustment member, which is not only conducive to simplifying the structure of the adjustment device, but also allows the support frame to be installed on the vehicle body fixing member through the adjustment member, and the position of the adjustment member relative to the vehicle body fixing member can be adjusted through the adjustment structure, thereby driving the support frame to move relative to the vehicle body fixing member, thereby conveniently adjusting the posture of the support frame relative to the vehicle body fixing member, and further facilitating the adjustment of the installation posture of the projection device in the vehicle through the adjustment device.

[0007] In a possible implementation of the present application, the support frame includes at least two support parts, and each support part is provided with an adjustment member.

[0008] In the technical solution of the present application, since at least two supporting parts are provided on the support frame, the support frame can be connected to the vehicle body fixing part through the adjusting member on each supporting part, which is conducive to improving the stability of the connection of the support frame to the vehicle body fixing part. In addition, the position of the support frame relative to the vehicle body fixing part can be adjusted from at least two points through at least two adjusting members, which is conducive to improving the flexibility of adjusting the position of the support frame.

[0010] In the technical solution of the present application, since a retaining member is provided in the adjusting device, the retaining member can always apply a force to the support frame away from the vehicle body fixing member. In this way, in the process of adjusting the position of the adjusting member relative to the vehicle body fixing member along the axial direction of the adjusting member, the support frame can automatically move in a direction away from the vehicle body fixing member under the force applied by the retaining member. And in the case of vibration of the vehicle body, the retaining member can play a role of vibration reduction and buffering to reduce the transmission of vibration to the support frame, thereby reducing the vibration impact on the projection device.

In addition, the connecting member is detachably connected to the body fixing member, which facilitates the installation of the connecting member on the body fixing member or the removal of the connecting member from the body fixing member.

[0013] In one possible implementation of the present application, the connecting member includes a fixing portion and a limiting portion; when the fixing portion is inserted into the vehicle body fixing member to install the connecting member on the vehicle body fixing member, the limiting portion abuts against the vehicle body fixing member to limit the movement of the connecting member relative to the vehicle body fixing member.

[0014] In the technical solution of the present application, since the connecting member includes a fixing portion, the connecting member can be inserted into the hole on the vehicle body fixing member through the fixing portion to detachably connect the connecting member to the vehicle body fixing member. In addition, the connecting member has a limiting portion, which can make the limiting portion abut against the vehicle body fixing member, thereby limiting the connection member from being separated from the vehicle body fixing member and limiting the connection member from rotating relative to the vehicle body fixing member, which is conducive to improving the reliability of the connection between the connecting member and the vehicle body fixing member.

[0015] In a possible implementation of the present application, the connecting piece is made of at least one of the following elastic materials: silicone and rubber.

[0016] In the technical solution of the present application, since the connecting piece is made of elastic material, it is convenient to insert the fixing part into the vehicle body fixing piece by extrusion, and the fixing part can be clamped and connected to the vehicle body fixing piece by utilizing the elastic restoring force of the connecting piece.

[0017] In a possible implementation of the present application, one of the adjustment structure and the connection structure includes an external thread, and the other includes a threaded hole matching the external thread.

[0018] In the technical solution of the present application, since the adjustment structure and the connection structure are external threads and threaded holes respectively, the adjustment member and the connection member can be connected by threaded connection. And the position of the adjustment member relative to the vehicle body fixing member can be adjusted by screwing the adjustment member, so as to facilitate the adjustment of the posture of the support frame relative to the vehicle body fixing member.

[0020] In the technical solution of the present application, since the support frame is provided with an adjustment part, and the projection device is provided with a mounting part matching the adjustment part, the projection device can be fixed on the support frame through the adjustment part and the mounting part. In addition, the adjustment part or the mounting part extends along the first direction, and the relative position between the mounting part and the adjustment part can be adjusted, so that the position of the projection device in the first direction can be adjusted.

[0021] In one possible implementation of the present application, the adjustment portion includes a boss extending along the axial direction of the adjusting member, and the mounting portion includes a long hole matching the boss; the boss has a fixing hole, and a fastener matching the fixing hole is used, and the head of the fastener is pressed against the edge of the long hole, so that the projection device can be fixedly mounted on the support frame.

[0022] In the technical solution of the present application, since the adjustment part includes a boss and a fixing hole, and the mounting part includes a long hole, the long hole can be moved relative to the boss, thereby adjusting the position of the projection device along the first direction. Moreover, a fastener can be connected to the fixing hole, so that the projection device can be fixedly connected to the support frame through the fastener.

[0023] In one possible implementation of the present application, the adjustment device of the projection equipment also includes a support member, which is arranged in an area on the support frame close to the adjustment part. By adjusting the position of the support member relative to the support frame, the support member can be abutted against the vehicle body fixing member to provide supporting force to the support frame.

[0024] In the technical solution of the present application, since a support member is provided on the support frame, the support member can be brought into contact with the body fixing member by adjusting the distance between the support member and the body fixing member, thereby providing supporting force to the portion of the support frame close to the adjustment portion, and furthermore, the support frame can be more stably connected to the body fixing member.

[0025] In one possible implementation of the present application, one of the adjusting member and the supporting portion has a spherical groove, and the other has a spherical protrusion matching the spherical groove; in the process of adjusting the position of the adjusting member relative to the vehicle body fixing member by adjusting the structure, the supporting portion rotates relative to the adjusting member with the cooperation of the spherical groove and the spherical protrusion.

[0026] In the technical solution of the present application, since the adjusting member and the supporting part are respectively provided with matching spherical grooves and spherical protrusions, spherical contact can be formed between the adjusting member and the supporting part. In this way, in the process of adjusting the position of the adjusting member relative to the vehicle body fixing member to drive the support frame to move relative to the vehicle body fixing member, the support frame can be smoothly and continuously rotated relative to the adjusting member, so that the position of the support frame relative to the vehicle body fixing member can be continuously and smoothly changed, which is conducive to improving the accuracy of adjusting the position of the projection device installed on the support frame relative to the vehicle body fixing member.

[0048] The present application provides an adjustment device for a projection device. Figure 1 and Figure 2 Both show the structural schematic diagrams of the vehicle-mounted projection system provided by the present application, Figure 3 Provided for this application Figure 2 A partial enlarged view of part A. Figure 4 The schematic diagram of the structure of the adjustment device of the projection device provided by the present application is shown. The adjustment device 1 includes: a support frame 11 and an adjustment member 12. The support frame 11 has a bearing portion 111 and a support portion 112; the bearing portion 111 matches the projection device 2 and is used to bear the projection device 2. The adjustment member 12 is arranged on the support portion 112, and the adjustment member 12 has an adjustment structure connected to the vehicle body fixing member 3; along the axial direction Z of the adjustment member 12, the position of the adjustment member 12 relative to the vehicle body fixing member 3 is adjusted by adjusting the adjustment structure, so that the adjustment member 12 can drive the support frame 11 to move relative to the vehicle body fixing member 3.

[0049] In the embodiment of the present application, the support frame 11 can provide support for the projection device 2 , and the projection device 2 can be installed on the vehicle through the support frame 11 .

[0050] For example, Figure 4 As shown, a bearing portion 111 matching with the projection device 2 can be provided on the support frame 11. For example, the bearing portion 111 can be provided in the form of a groove structure, and a part of the projection device 2 can be accommodated in the groove. A support portion 112 can also be provided on the support frame 11. For example, the support portion 112 can be formed by extending from the edge of the bearing portion 111, so that the support frame 11 can be connected to the vehicle body fixing part 3 through the support portion 112.

[0051] In the embodiment of the present application, the adjusting member 12 is used to install the support frame 11 on the body fixing member 3, and by adjusting the position of the adjusting member 12 relative to the body fixing member 3, the support frame 11 is driven to move relative to the body fixing member 3 to adjust the position of the support frame 11 relative to the body fixing member 3.

[0052] For example, Figure 1 , Figure 2 and Figure 4 As shown, the adjusting member 12 can be connected to the supporting portion 112, such as by movably connecting the adjusting member 12 and the supporting portion 112 through the structure of an axis and a hole. An adjusting structure connected to the vehicle body fixing member 3 can also be provided on the adjusting member 12, so as to connect the adjusting member 12 to the vehicle body fixing member 3 by using the adjusting structure. For example, the adjusting member 12 can be a bolt, and the adjusting structure is an external thread. In this way, along the axial direction Z of the adjusting member 12, by adjusting the position of the adjusting member 12 relative to the vehicle body fixing member 3, the adjusting member 12 can drive the support frame 11 to move relative to the vehicle body fixing member 3, so that the position of the support frame 11 relative to the vehicle body fixing member 3 can be adjusted.

[0053] The adjustment device 1 of the projection device provided in the present application, since a bearing portion 111 is provided on the support frame 11, the bearing portion 111 can provide an installation position for the projection device 2. In addition, an adjustment member 12 is provided on the support portion 112 of the support frame 11, and an adjustment structure is provided on the adjustment member 12, which is not only conducive to simplifying the structure of the adjustment device 1, but also allows the support frame 11 to be installed on the vehicle body fixing member 3 through the adjustment member 12, and the position of the adjustment member 12 relative to the vehicle body fixing member 3 can be adjusted through the adjustment structure, so that the support frame 11 can be driven to move relative to the vehicle body fixing member 3, so that the posture of the support frame 11 relative to the vehicle body fixing member 3 can be conveniently adjusted, and then it is convenient to adjust the installation posture of the projection device 2 in the vehicle through the adjustment device 1.

[0054] In some possible embodiments of the present application, the support frame 11 includes at least two support portions 112 , and each support portion 112 is provided with an adjustment member 12 .

[0055] In the present application embodiment, Figure 1 , Figure 2 and Figure 4 As shown, at least two support portions 112 may be provided on the support frame 11, and an adjusting member 12 may be provided for each support portion 112. For example, along the first direction F, a support portion 112 may be extended on both sides of the support frame 11 to form a support portion 112. The plane where each support portion 112 is located is parallel or nearly parallel to the plane where the bearing portion 111 is located.

[0056] In the above embodiment, since at least two supporting parts 112 are provided on the supporting frame 11, the supporting frame 11 can be connected to the vehicle body fixing part 3 through the adjusting member 12 on each supporting part 112, which is conducive to improving the stability of the connection of the supporting frame 11 to the vehicle body fixing part 3. In addition, the position of the supporting frame 11 relative to the vehicle body fixing part 3 can be adjusted from at least two points through at least two adjusting members 12, which is conducive to improving the flexibility of adjusting the position of the supporting frame 11.

[0057] In some possible embodiments of the present application, refer to Figure 5 , Figure 5 The schematic diagram of the partial cross-section structure of the adjustment device of the projection device provided by the present application is shown. The adjustment device 1 of the projection device also includes a retaining member 13; when the adjustment member 12 is connected to the vehicle body fixing member 3, one end of the retaining member 13 abuts against the vehicle body fixing member 3, and the other end abuts against the support frame 11, and the retaining member 13 can apply a force to the support frame 11 away from the vehicle body fixing member 3.

[0058] In the present application embodiment, Figure 2 , Figure 4 and Figure 5 As shown, a retaining member 13 may be provided in the adjusting device 1 , so that a force acting on the support frame 11 away from the vehicle body fixing member 3 is applied through the retaining member 13 .

[0059] Exemplarily, the retaining member 13 may be a compression spring, a rubber spring, etc. For example, the compression spring may be sleeved on the adjusting member 12, so that one end of the compression spring abuts against the supporting portion 112, and the other end abuts against the vehicle body fixing member 3. Alternatively, a rubber spring or the like may be provided between the bearing portion 111 and the vehicle body fixing member 3. In this way, the retaining member 13 may always exert a force on the support frame 11 to keep away from the vehicle body fixing member 3.

[0060] In the above embodiment, since the adjusting device 1 is provided with the retaining member 13, the retaining member 13 can always apply a force to the support frame 11 to move away from the vehicle body fixing member 3. In this way, in the process of adjusting the position of the adjusting member 12 relative to the vehicle body fixing member 3 along the axial direction Z of the adjusting member 12, the support frame 11 can automatically move in a direction away from the vehicle body fixing member 3 under the force applied by the retaining member 13. In addition, when the vehicle body vibrates, the retaining member 13 can play a role of vibration reduction and buffering to reduce the transmission of vibration to the support frame 11, thereby reducing the vibration impact on the projection device 2.

[0061] In some possible embodiments of the present application, refer to Figure 6 , Figure 6The schematic diagram of the structure of the connecting member in the adjustment device of the projection device provided in the present application. The adjustment device 1 of the projection device also includes a connecting member 14, on which there is a connecting structure 143 matching the adjustment structure, and the adjustment member 12 is movably connected to the connecting member 14 through the cooperation of the adjustment structure and the connecting structure 143; the connecting member 14 matches the vehicle body fixing member 3 and can be detachably installed on the vehicle body fixing member 3.

[0062] In the present application embodiment, Figure 2 , Figure 5 and Figure 6 As shown, in order to facilitate the connection of the adjusting member 12 with the vehicle body fixing member 3 , a connecting member 14 may be provided in the adjusting device 1 .

[0063] For example, a connection structure 143 matching the adjustment structure can be provided on the connection member 14, and the adjustment structure and the connection structure 143 can be provided as structures that can achieve connection and generate relative movement. For example, the adjustment structure and the connection structure 143 can be a sliding groove and a slider with interference fit, or a sliding groove with a wavy protrusion and a guide rail with a wavy protrusion, etc.

[0064] In another example, the structure of the connecting member 14 can be set according to the structural shape of the body fixing member 3 so that the connecting member 14 matches the body fixing member 3. The connecting member 14 can be connected to the body fixing member 3 in a detachable manner such as snap connection, thread connection, or bonding.

[0065] In the above embodiment, since the connecting member 14 has a connecting structure 143 matching the adjustment structure, the connection between the adjusting member 12 and the connecting member 14 can be realized through the adjustment structure and the connecting structure 143, and the position of the adjusting member 12 relative to the connecting member 14 can be adjusted, thereby facilitating the adjustment of the posture of the support frame 11. In addition, the connecting member 14 is detachably connected to the vehicle body fixing member 3, which facilitates the installation of the connecting member 14 on the vehicle body fixing member 3 or the removal of the connecting member 14 from the vehicle body fixing member 3.

[0066] In some possible embodiments of the present application, Figure 6 As shown, the connecting member 14 includes a fixing portion 141 and a limiting portion 142; when the fixing portion 141 is inserted into the body fixing member 3 to install the connecting member 14 on the body fixing member 3, the limiting portion 142 abuts against the body fixing member 3 to limit the movement of the connecting member 14 relative to the body fixing member 3.

[0067] In the present application embodiment, Figure 5 As shown, a through hole may be provided on the vehicle body fixing component 3 so that the connecting component 14 can be detachably mounted on the vehicle body fixing component 3 through the through hole.

[0068] For example, the connecting member 14 may be configured to include a fixing portion 141 and a limiting portion 142. The fixing portion 141 may be a column that matches the through hole on the vehicle body fixing member 3. If the through hole is a circular hole, the column is a cylindrical body. The column and the through hole may be interference fit structures, so that the column can be stably inserted into the through hole.

[0069] In another example, a limiting portion 142 may be provided on the connecting member 14. For example, the limiting portion 142 is provided on one side of the connecting member 14 adjacent to the fixing portion 141, the limiting portion 142 and the fixing portion 141 are oriented in the same direction on the connecting member 14, and an angle less than 90° is formed between the limiting portion 142 and the fixing portion 141, that is, the free end of the limiting portion 142 is inclined toward the fixing portion 141. In this way, after the fixing portion 141 is connected to the vehicle body fixing member 3, the limiting portion 142 may be abutted against or clamped on the edge of the vehicle body fixing portion 141.

[0070] In the above embodiment, since the connecting member 14 includes the fixing portion 141, the connecting member 14 can be inserted into the hole on the vehicle body fixing member 3 through the fixing portion 141 to detachably connect the connecting member 14 to the vehicle body fixing member 3. In addition, the connecting member 14 has a limiting portion 142, which can be brought into contact with the vehicle body fixing member 3, thereby limiting the connection member 14 from being separated from the vehicle body fixing member 3, and limiting the connection member 14 from rotating relative to the vehicle body fixing member 3, which is conducive to improving the reliability of the connection between the connecting member 14 and the vehicle body fixing member 3.

[0071] In some possible embodiments of the present application, the connecting member 14 is made of at least one of the following elastic materials: silicone and rubber.

[0072] In the embodiment of the present application, the connecting member 14 may be made of an elastic material, so that at least the fixing portion 141 has elasticity, so as to facilitate inserting the fixing portion 141 into the vehicle body fixing member 3 .

[0073] Exemplarily, the connector 14 can be made of materials such as silicone and rubber that are elastic and have high tensile strength, thermal stability, and chemical stability.

[0074] In the above embodiment, since the connecting member 14 is made of elastic material, the fixing portion 141 can be inserted into the vehicle body fixing member 3 by extrusion, and the fixing portion 141 can be clamped and connected to the vehicle body fixing member 3 by utilizing the elastic restoring force of the connecting member 14 .

[0075] In some possible embodiments of the present application, one of the adjustment structure and the connection structure 143 includes an external thread, and the other includes a threaded hole matching the external thread.

[0076] In the present application embodiment, Figure 5 and Figure 6 As shown, the adjustment structure on the adjusting member 12 and the connection structure 143 on the connecting member 14 can be a threaded connection structure 143 .

[0077] For example, an external thread may be provided on the adjusting member 12, and correspondingly, an internal thread may be provided on the connecting member 14, for example, an embedded nut may be provided on the connecting member 14. Alternatively, a threaded column may be provided on the connecting member 14, and correspondingly, a threaded hole matching the threaded column may be provided on the adjusting member 12.

[0078] In the above embodiment, since the adjustment structure and the connection structure 143 are external threads and threaded holes respectively, the adjustment member 12 and the connection member 14 can be connected by threaded connection. And the position of the adjustment member 12 relative to the vehicle body fixing member 3 can be adjusted by screwing the adjustment member 12, so as to facilitate the adjustment of the posture of the support frame 11 relative to the vehicle body fixing member 3.

[0079] In some possible embodiments of the present application, Figure 2 and Figure 3 As shown, the support frame 11 also has an adjustment portion 113 that matches the mounting portion 23 on the projection device 2. The support frame 11 includes two support portions 112. The adjustment portion 113 or the mounting portion 23 is extended along a first direction F. The first direction F and the connection direction of the two support portions 112 are parallel. The projection device 2 can be detachably mounted on the mounting portion 23 through the adjustment portion 113 and the mounting portion 23. By adjusting the relative positions of the adjustment portion 113 and the mounting portion 23 along the first direction F, the position of the projection device 2 relative to the support frame 11 along the first direction F can be adjusted.

[0080] In the embodiment of the present application, an adjustment portion 113 may be provided on the support frame 11 , and correspondingly, a mounting portion 23 may be provided on the projection device 2 , so that the projection device 2 may be fixed on the support frame 11 via the adjustment portion 113 and the mounting portion 23 .

[0081] Exemplarily, two support parts 112 may be provided on the support frame 11, and the two support parts 112 are distributed on the support frame 11 along the first direction F. The adjustment part 113 or the mounting part 23 may be extended along the first direction F. For example, the mounting part 23 may be provided as a cylinder, and the adjustment part 113 may be provided as a long hole, and the size of the long hole along the first direction F is greater than the diameter of the cylinder. In this way, the adjustment part 113 and the mounting part 23 may be able to generate relative movement along the first direction F. The adjustment part 113 and the mounting part 23 whose relative positions have been adjusted may also be fixedly connected by a fastener 16 to limit the movement of the projection device 2 relative to the support frame 11.

[0082] In the above embodiment, since the support frame 11 is provided with the adjusting portion 113, and the projection device 2 is provided with the mounting portion 23 matching the adjusting portion 113, the projection device 2 can be fixed on the support frame 11 through the adjusting portion 113 and the mounting portion 23. In addition, the adjusting portion 113 or the mounting portion 23 extends along the first direction F, and the relative position between the mounting portion 23 and the adjusting portion 113 can be adjusted, so that the position of the projection device 2 in the first direction F can be adjusted.

[0083] In some possible embodiments of the present application, the adjustment portion 113 includes a boss 1131 extending along the axial direction Z of the adjusting member 12, and the mounting portion 23 includes a long hole matching the boss 1131; the boss 1131 has a fixing hole 1132, and a fastener 16 matching the fixing hole 1132 is used, and the head of the fastener 16 is pressed against the edge of the long hole, so that the projection device 2 can be fixedly mounted on the support frame 11.

[0084] In the present application embodiment, Figure 3 As shown, the adjustment portion 113 can be set to a structure including a boss 1131 and a fixing hole 1132. The boss 1131 is formed by extending from the surface of the support frame 11, and the extension direction of the boss 1131 is the same as the axial direction Z of the adjustment member 12. For example, the boss 1131 can be set as a cylindrical protrusion. The fixing hole 1132 can be set on the cylindrical protrusion, and the fixing hole 1132 can be a through hole or a threaded hole. Correspondingly, the mounting portion 23 can be configured as a long hole, and the length of the long hole in the first direction F is greater than the diameter of the boss 1131. Then the boss 1131 can be located in the long hole, and the long hole can be moved relative to the boss 1131 along the first direction F, so that the position of the projection device 2 relative to the support frame 11 in the first direction F can be adjusted. Alternatively, along the first direction F, the length of the long hole is smaller than the diameter of the boss 1131 and larger than the diameter of the fastener 16. The surface of the long hole can be pressed against the surface of the boss 1131, so that the long hole can move along the first direction F relative to the fastener 16. In this way, the position of the projection device 2 relative to the support frame 11 in the first direction F can also be adjusted.

[0085] Exemplarily, a fastener 16 matching the fixing hole 1132 on the boss 1131 may be provided, so that the edge of the long hole is pressed and fixed by the fastener 16, so that the projection device 2 is fixed relative to the support frame 11. For example, the fastener 16 may be a bolt, which is screwed into the threaded hole on the boss 1131, and the head of the bolt presses and fixes the edge of the long hole. The fastener 16 may also be an elastic buckle, a part of which is connected to the fixing hole 1132, and the elastic buckle is pressed and fixed to the support frame 11 by changing the posture of the elastic buckle.

[0086] In the above embodiment, since the adjustment portion 113 includes the boss 1131 and the fixing hole 1132, and the mounting portion 23 includes the long hole, the long hole can be moved relative to the boss 1131, so that the position of the projection device 2 along the first direction F can be adjusted. Moreover, the fastener 16 can be connected to the fixing hole 1132, so that the projection device 2 can be fixedly connected to the support frame 11 through the fastener 16.

[0087] In some possible embodiments of the present application, Figure 3 and Figure 4 The adjustment device 1 of the projection device also includes a support member 15, which is arranged on the support frame 11 in an area close to the adjustment portion 113. By adjusting the position of the support member 15 relative to the support frame 11, the support member 15 can be abutted against the vehicle body fixing member 3 to provide supporting force for the support frame 11.

[0088] In the embodiment of the present application, after the support frame 11 is connected to the vehicle body fixing member 3 by the adjusting member 12, the support frame 11 may shake relative to the vehicle body fixing member 3. Then, a support member 15 may be provided on the support frame 11 to provide more support to the support frame 11 through the support member 15.

[0089] For example, the support member 15 may be disposed in an area of ​​the support frame 11 close to the adjustment portion 113, that is, the support member 15 may be disposed in an area of ​​the support frame 11 away from the support portion 112. For example, the support member 15 may be a bolt, and the bolt may be disposed on the support frame 11 along the axial direction Z of the adjustment member 12. In this way, by screwing the bolt, the bolt may extend toward the portion of the vehicle body fixing member 3 by different lengths, so that the bolt may abut against the vehicle body fixing member 3, thereby providing a supporting force to the portion of the support frame 11 away from the support portion 112.

[0090] In the above embodiment, since the support member 15 is provided on the support frame 11, the support member 15 can be brought into contact with the body fixing member 3 by adjusting the distance between the support member 15 and the body fixing member 3, thereby providing a supporting force to the portion of the support frame 11 close to the adjustment portion 113, and furthermore, the support frame 11 can be more stably connected to the body fixing member 3.

[0091] In some possible embodiments of the present application, Figure 5 As shown, one of the adjusting member 12 and the supporting portion 112 has a spherical groove 1121, and the other has a spherical protrusion 122 matching the spherical groove 1121; in the process of adjusting the position of the adjusting member 12 relative to the vehicle body fixing member 3 by adjusting the structure, the supporting portion 112 rotates relative to the adjusting member 12 under the cooperation of the spherical groove 1121 and the spherical protrusion 122.

[0092] In the embodiment of the present application, when adjusting the position of the adjusting member 12 relative to the vehicle body fixing member 3, the support frame 11 swings relative to the adjusting member 12 driven by the adjusting member 12, and a structure that enables the support frame 11 to swing smoothly can be provided between the adjusting member 12 and the support portion 112.

[0093] For example, Figure 5 As shown, a spherical protrusion 122 can be provided on one end of the adjusting member 12 close to the supporting portion 112. For example, when the adjusting member 12 adopts a bolt, a part of the head of the bolt can be processed into a spherical surface. Correspondingly, a spherical groove 1121 matching the spherical protrusion 122 can be provided on the supporting portion 112. Alternatively, the spherical groove 1121 can be provided on the adjusting member 12, and the spherical protrusion 122 can be provided on the supporting portion 112. In this way, after the spherical protrusion 122 abuts against the spherical groove 1121, a spherical contact can be formed between the adjusting member 12 and the supporting portion 112, so that the supporting portion 112 can rotate smoothly around the spherical protrusion 122.

[0094] In the above embodiment, since the adjusting member 12 and the supporting portion 112 are respectively provided with matching spherical grooves 1121 and spherical protrusions 122, spherical contact can be formed between the adjusting member 12 and the supporting portion 112. In this way, in the process of adjusting the position of the adjusting member 12 relative to the vehicle body fixing member 3 to drive the support frame 11 to move relative to the vehicle body fixing member 3, the support frame 11 can be smoothly and continuously rotated relative to the adjusting member 12, so that the position of the support frame 11 relative to the vehicle body fixing member 3 can be continuously and smoothly changed, which is conducive to improving the accuracy of adjusting the position of the projection device 2 installed on the support frame 11 relative to the vehicle body fixing member 3. And when two supporting portions 112 are provided on the support frame 11, and an adjusting member 12 is provided for each supporting portion 112, when one of the adjusting members 12 is adjusted, the support frame 11 can also rotate around the other adjusting member 12, so that the height and angle of the projection device 2 installed on the support frame 11 can be adjusted.

[0095] In addition, the embodiment of the present application also provides a vehicle-mounted projection system, such as Figure 1 and Figure 2 As shown, the vehicle-mounted projection system comprises: a projection device 2 and an adjustment device 1 for the projection device provided by any one of the above embodiments. The projection device 2 is fixed on the bearing part 111 .

[0096] In the embodiment of the present application, the projection device 2 can generate a projection light beam, and the projection light beam can form a projection picture after being transmitted to the screen or the surface inside the cabin.

[0097] Exemplarily, the projection device 2 may be fixedly mounted on the support frame 11 in the adjustment device 1. For example, the bearing portion 111 on the support frame 11 is configured to match the bottom of the projection device 2, and the projection device 2 may be fixed on the bearing portion 111.

[0098] The vehicle-mounted projection system provided in the embodiment of the present application has the projection device 2 installed on the support frame 11 of the adjustment device 1, so that the projection device 2 can be installed on the vehicle body through the adjustment member 12 and the support frame 11, and the installation position of the projection device 2 in the vehicle body can be easily adjusted through the adjustment device 1.

[0099] In some possible embodiments of the present application, refer to Figure 7 , Figure 7 The cross-sectional structure diagram of the projection device in the vehicle-mounted projection system provided by the present application is shown. The projection device 2 includes a reflective housing 221 and at least two reflective members 222; the reflective housing 221 is connected to the lens assembly 21 of the projection device 2, and the reflective housing 221 has a mounting port 2211 matching each reflective member 222, and each mounting port 2211 is located on the transmission path C of the projection light beam transmitted through the lens assembly 21; each reflective member 222 is installed on a mounting port 2211; the projection light beam transmitted through the lens assembly 21 is transmitted in different directions under the reflection of at least two reflective members 222.

[0100] In the present application embodiment, Figure 2 and Figure 7 As shown, a reflection component 22 may be installed on the lens component 21 of the projection device 2 to change the transmission direction of the projection light beam transmitted from the lens component 21 through the reflection component 22 .

[0101] For example, Figure 7 As shown, the reflective assembly 22 includes a reflective housing 221 and a reflective member 222. The reflective housing 221 can provide a mounting position for the reflective member 222. The reflective housing 221 can be set as a structure matching the housing of the lens assembly 21, so that the reflective housing 221 can be fixed on the housing of the lens assembly 21. Along the transmission path C of the projection light beam transmitted through the lens assembly 21, two mounting ports 2211 can be set on the reflective housing 221 on a side away from the lens assembly 21, and each mounting port 2211 matches the reflective member 222. For example, the reflective member 222 can be a plane reflector. In this way, the two reflective members 222 can be respectively mounted on the two mounting ports 2211, and the two plane reflectors can respectively reflect the projection light beams to opposite directions. The two reflective members 222 can be two separate plane reflectors, or a whole reflector of an integrated structure, and the reflector of the integrated structure has two reflective surfaces arranged at an angle greater than 90° and less than 180°.

[0102] In another example, each reflector 222 may be movably mounted on the mounting opening 2211, for example, the reflector 222 may be rotatably mounted on the mounting opening 2211 via a rotating shaft, so as to adjust the angle between the reflector 222 and the transmission path C. The edge of the reflector 222 may be sealed and connected to the mounting opening 2211 via a flexible material.

[0103] In another example, a protective member 223 may be provided on the exit port 2212 of the projected light beam on the reflective housing 221, so that the exit port 2212 is sealed by the protective member 223. For example, the protective member 223 may be a plane lens, such as a plane lens made of B270 glass. The protective member 223 is installed on the exit port 2212 in a sealed connection. In this way, a sealed space can be formed in the reflective housing 221, which is conducive to reducing dust from entering the reflective housing 221.

[0104] In the above embodiment, since at least two reflectors 222 are provided on the transmission path C of the projection light beam transmitted through the lens assembly 21, the projection light beam can be reflected to different directions by the two reflectors 222, thereby forming at least two projection images. In this way, the reflector 222 can be matched with the adjustment device 1, so that the position adjustment of the projection image can be achieved better and within a larger range.

The vehicle body fixture 3 is a structural member on the vehicle body for mounting the projection device 2. For example, the vehicle body fixture 3 can be an interior decoration member in the cabin or a sheet metal member outside the vehicle body. The embodiment of the present application does not limit the specific position of the vehicle body fixture 3.

[0107] Exemplarily, the adjusting member 12 in the adjusting device 1 may be connected to the vehicle body fixing member 3 so as to mount the supporting frame 11 on the vehicle body fixing member 3 , thereby mounting the projection device 2 on the vehicle body fixing member 3 .
