Embodiments of the present application

[0034] In the description of the present application, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] In the present application, unless specifically defined and limited otherwise, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, and the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, and the horizontal height of the first feature is less than that of the second feature.

[0036] In the description of the present embodiment, the terms "upper", "lower", "left", "right", "front", "back" and the like orientation or position relationship are based on the orientation or position relationship shown in the drawings, which is for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used to distinguish in the description and have no special meaning.

[0037] In the related art, display devices such as projectors, commercial display devices, and televisions do not generally have touch interaction functions. The main reasons are: high price of touch function, aesthetic requirements, limited installation scenarios, etc. With the gradual diversification of the use of display devices by users, touch interaction functions have gradually become a necessary function of display devices. Adding touch interaction functions can greatly improve the interactive fun of products and product competitiveness.

[0038] Current touch interaction technologies mainly include capacitive touch screen technology and infrared frame touch screen technology. For capacitive touch screen technology, it has the advantages of high precision, small delay, etc., and can realize touch and writing functions. However, it is high in price, complex in bonding process, needs to be matched with screen size one by one, and will affect the display color of the screen. For infrared frame touch screen technology, it has the advantages of high precision, small delay, etc., and can realize touch and writing functions. However, it will affect the aesthetics of the screen and needs to be matched with screen size one by one. Moreover, the price of large-size infrared frame is high and the precision is low, which is difficult to apply to current large-screen display devices.

[0039] In order to reduce the cost of introducing touch interaction function in large screen display device, a technology of applying laser radar device 50 to display device 40 to realize touch interaction is developed, as shown in FIG. 10. The basic principle is that the laser transceiver is driven to rotate by the motor of the laser radar, and the laser scanning surface 60 is formed on the surface of the display device 40. When an object touches the screen of the display device 40, the scanning line of the laser radar will be blocked, and the specific coordinate position of the blocked scanning line can be obtained. Further, the information corresponding to the coordinate position of the display device 40 is synchronously reflected based on the coordinate position, so as to realize touch interaction.

[0040] However, due to the limitation of production process, the laser beam emitted by the laser radar device 50 usually has a pitch angle. As shown in FIG. 9, theoretically, the laser beam is horizontally emitted in the direction of S1, but due to the limitation of production process, the laser beam is actually tilted and emitted in the direction of S2. The laser scanning surface 60 is actually a conical surface, which causes the distance between the laser scanning surface 60 and the display device 40 to be too large. Especially at the position far away from the laser radar device 50, the vertical distance between the laser scanning surface 60 and the display device 40 reaches the maximum value. Thus, it is easy to cause poor accuracy of touch interaction and poor user experience.

[0041] Embodiment one

[0042] Please refer to FIGS. 1-16, the embodiment of the present application provides an adjusting device for adjusting the posture of the laser radar device 50. Specifically, the adjusting device is applied to the laser radar device 50 installed on the display device 40. The adjusting device includes a support 10, a panel 30 and an optical surface 20. The support 10 is used to contact the surface of the display device 40, so that the optical surface 20 forms a right angle with the surface of the display device 40. The panel 30 is connected perpendicularly to the support 10, and the optical surface 20 is arranged on the panel 30. The optical surface 20 is used to receive the light emitted by the laser radar device 50. The width of the optical surface 20 increases or decreases along the direction perpendicular to the surface of the display device 40, so that the light intensity of the reflected light reflected to the laser radar device 50 after the optical surface 20 receives the light reflected by the laser radar device 50 is different.

[0043] The embodiment of the present application installs the device on the display device 40 after the laser radar device 50 is installed on the display device 40. The optical surface 20 processes the light (laser beam) emitted by the laser radar device 50. Because the width of the optical surface 20 increases or decreases in the direction perpendicular to the screen of the display device 40, the number of point clouds obtained by the laser radar device 50 based on the reflected light of different widths of the optical surface 20 is different; that is, based on the shape of the optical surface 20, the reflected light received by the laser radar device 50 changes regularly when the radar posture of the laser radar device 50 is adjusted, and the number of point clouds obtained by the reflected light changes regularly. Based on the change result, it can be known whether the radar posture adjustment of the laser radar device 50 is correct. And based on the correct adjustment direction, subsequent adjustment is carried out, so that the laser beam of the laser radar device 50 is as close as possible to the display device 40, and the accuracy of touch interaction is improved.

[0044] It can be understood that the support 10 is used to contact the display device 40, so that the optical surface 20 can be fixed to the front side of the display device 40. The laser radar device 50 is installed on the top of the display device 40, and the laser beam emitted by the laser radar device 50 can be reflected on the optical surface 20. Because the light intensity of the reflected light of the optical surface 20 is different from the light intensity of the reflected light of the surrounding environment, the laser radar can identify which reflected light is the reflected light of the optical surface 20.

[0045] The optical surface 20 extends in the direction perpendicular to the display device 40. And the width of the optical surface 20 increases or decreases in the direction perpendicular to the screen of the display device 40. The width of the optical surface 20 can be identified according to the conical laser scanning surface 60 formed by the laser radar device 50. When the radar posture of the laser radar device 50 is adjusted, the laser scanning surface 60 will move, so that the width of the optical surface 20 identified changes, so that the adjustment direction of the radar posture is determined based on the change rule.

[0046] It can be understood that based on the increase or decrease of the width of the optical surface 20, the number of point clouds of the reflected light of the optical surface 20 can increase or decrease. Based on the change of the number of point clouds, the light intensity can also be different, so that the laser radar device 50 can adjust the posture of the laser radar device 50 based on the reflected light of the optical surface 20.

[0047] As shown in FIG. 2, in some embodiments, the optical surface 20 can be set as an isosceles triangle. If the top angle of the isosceles triangle is set away from the display device 40, the width of the optical surface 20 increases in the direction close to the display device 40. If the top angle of the isosceles triangle is set close to the display device 40, the width of the optical surface 20 decreases in the direction close to the display device 40.

[0048] In other embodiments of the present application, the optical surface 20 can also be provided in the shape of an equilateral triangle, a right triangle, or other triangles. As shown in FIG. 17, the optical surface 20 can also be provided in the shape of a trapezoid. As shown in FIG. 18, the optical surface can also be provided in the shape of a semicircle or a semi-ellipse. In other embodiments of the present application, the optical surface 20 can also be provided in other gradually changing shapes, as long as the width of the optical surface 20 gradually changes along the direction perpendicular to the screen of the display device 40.

[0049] The shape of the panel 30 can be adapted to the shape of the optical surface 20. For example, the panel 30 can gradually change in width along the direction close to the screen of the display device 40. When the optical surface 20 is in the shape of an isosceles triangle, the panel 30 is also provided in the shape of an isosceles triangle.

[0050] Based on the fact that the panel 30 extends along the direction perpendicular to the display device 40, after the panel 30 supports the optical surface 20, the optical surface 20 can be fixed on a plane perpendicular to the screen of the display device 40. This facilitates the reflection of the laser beam by the optical surface 20. The panel 30 as a component for supporting the optical surface 20 can be manufactured by 3D printing. Of course, the panel 30 can also be manufactured by integrally injection molding using an injection molding machine.

[0051] The optical surface 20 in the embodiments of the present application refers to an optical surface that can reflect or absorb light. The reflection capability of the optical surface 20 for light will be different from the reflection capability of the surrounding environment of the display device 40. Thus, the light intensity of the reflected light of the optical surface 20 can be different from the light intensity of the reflected light of the surrounding environment of the display device 40, so that the laser radar device 50 can identify which reflected light is the reflected light of the optical surface 20. For example, the optical surface 20 can be made of a highly reflective material, so that the light intensity of the reflected light of the optical surface 20 is greater than the light intensity of the reflected light of the surrounding environment of the display device 40. For example, the optical surface 20 can be made of a light-absorbing material, so that the light intensity of the reflected light of the optical surface 20 is less than the light intensity of the reflected light of the surrounding environment of the display device 40.

[0052] It should be noted that the surrounding environment of the display device 40 referred to in the embodiments of the present application includes the ground, the wall, the workbench, the clamp, etc.

[0053] The optical surface 20 can be integrally formed on the panel 30, or the optical surface 20 can be provided separately from the panel 30. For example, the optical surface 20 can be bonded to the panel 30; the optical surface 20 can also be adsorbed to the panel 30; or the optical surface 20 can be sleeved on the panel 30.

[0054] The optical surface 20 can also be a surface formed by an optical material coated on the panel 30. For example, a light-reflecting coating is coated on the panel 30 to form the optical surface 20 that can reflect light; a light-absorbing coating is coated on the panel 30 to form the optical surface 20 that can absorb light.

[0055] The support 10 in the embodiments of the present application is used to contact the display device 40 to fix the position of the device on the display device. For example, the support 10 can be bonded to the display device 40. For example, the support 10 can be fixed to the display device 40 by a clamp. For example, the support 10 can be connected to the display device 40 by magnetic attraction.

[0056] In the embodiments of the present application, the adjustment of the posture is specifically the adjustment of the posture of the lidar device 50 installed on the display device. Based on the adjustment device used to assist in adjusting the posture (e.g., the pitch angle and the yaw angle) of the lidar device 50, the laser scanning surface 60 of the lidar device 50 can be adjusted from the scanning position shown in FIG. 10 to the scanning position shown in FIG. 11. The laser scanning surface 60 can be close to the display device 40, and the vertical distance between the laser scanning surface 60 and the screen of the display device 40 is minimized, thereby improving the accuracy of touch interaction.

[0057] As shown in FIGS. 7 and 8, in some embodiments, the panel 30 has an installation region 310 and a non-installation region 320 in a direction perpendicular to the surface of the display device 40, the non-installation region 320 is disposed close to the support 10, wherein the optical surface 20 is disposed on the installation region 310, and the reflected light intensity of the optical surface 20 is different from that of the non-installation region 320.

[0058] It can be understood that the installation region 310 is used to install the optical surface 20. For example, the optical surface 20 is a high-reflective material sticker, and the high-reflective material sticker is pasted on the installation region 310.

[0059] With the continuous correction of the radar posture of the lidar device 50, the laser scanning surface 60 will gradually approach the display device 40. When the laser scanning surface 60 moves from the installation region 310 to the non-installation region 320, the number of point clouds received by the lidar device 50 will suddenly change. Therefore, the end time of the radar posture correction can be known, and over-adjustment can be prevented.

[0060] For example, when the optical surface 20 is a high-reflective material sticker, and the width of the optical surface 20 increases in the direction close to the display device 40. During the adjustment of the radar posture, the number of high-reflective point clouds obtained will gradually increase. When the number of high-reflective point clouds suddenly decreases, or even becomes 0, it indicates that the laser scanning surface 60 has been adjusted to the non-installation region 320. At this time, the distance between the laser scanning surface 60 and the display device 40 can meet the demand of high-precision touch interaction, and the adjustment of the radar posture can be stopped.

[0061] For example, when the optical surface 20 is a light-absorbing material sticker, and the width of the optical surface 20 decreases along the direction close to the display device 40. In the process of adjusting the radar posture, the number of points of the low-reflection point cloud obtained will gradually decrease. When the number of points of the low-reflection point cloud suddenly becomes 0, it means that the laser scanning surface 60 has moved to the non-mounting area 320. At this time, the distance between the laser scanning surface 60 and the display device 40 can meet the high-precision touch interaction requirement, and the adjustment of the radar posture can be stopped.

[0062] The non-mounting area 320 can also be used to form a gap with a certain width between the optical surface 20 and the display device 40.

[0063] In the process of adjusting the radar posture, if the laser scanning surface 60 of the laser radar device 50 completely adheres to the screen of the display device 40, the screen will become an obstacle to the laser scanning surface 60, which will affect the touch interaction of the display device 40, and at this time the screen will reflect the laser beam, which may reflect the laser beam onto the optical surface 20. Then the laser beam is reflected again to the laser radar device 50 through the optical surface 20. At this time, although the laser radar device 50 can still receive a high-reflection point cloud or a low-reflection point cloud, it will cause the time point of stopping adjusting the radar posture to be unable to be determined, resulting in over-adjustment or misadjustment.

[0064] When the frame of the display device 40 protrudes from the screen, if the laser scanning surface 60 of the laser radar device 50 adheres to the screen after adjusting the radar posture, then in the process of use, the laser scanning surface 60 will continuously scan the frame, and the frame will interfere with the laser scanning surface 60, affecting the accuracy of the touch interaction.

[0065] As shown in FIG. 7, the width of the non-mounting area 320 is D along the direction perpendicular to the display device 40. 1 millimeter ≤ D ≤ 10 millimeters. For example, D = 5 millimeters. Based on leaving a gap of 5 millimeters between the optical surface 20 and the display device 40, the laser scanning surface 60 is prevented from adhering to the screen, and the laser scanning surface 60 is prevented from scanning the frame of the display device 40.

[0066] The width D of the non-mounting area 320 can be reasonably selected based on different models of display devices 40 or different signals of laser radar devices 50. For example, the width of the non-mounting area 320 can be selected based on the spot diameter formed by the laser beam emitted by the laser radar device 50, so that the width of the non-mounting area 320 is greater than the spot diameter formed by the laser beam.

[0067] In some embodiments, the optical surface 20 is a reflective material, and the light intensity of the reflected light of the optical surface 20 is greater than the light intensity of the reflected light of the surrounding environment. For example, the optical surface 20 is a high-reflection material sticker.

[0068] When the laser scanning surface 60 of the lidar device 50 scans the optical surface 20, based on the high-reflective characteristic of the optical surface 20, the lidar device 50 can obtain a number of high-reflective point clouds reflected by the optical surface 20. The surrounding environment cannot cause the laser beam to reflect to form a high-reflective point cloud.

[0069] When the width of the optical surface 20 increases along the direction close to the screen of the display device 40, if the number of the obtained high-reflective point clouds increases during the adjustment of the radar attitude, it indicates that the width of the optical surface 20 scanned by the lidar device gradually increases. At this time, the laser scanning surface 60 moves towards the direction away from the display device 40, and the radar attitude needs to be adjusted in the opposite direction.

[0070] When the width of the optical surface 20 decreases along the direction close to the screen of the display device 40, if the number of the obtained high-reflective point clouds increases during the adjustment of the radar attitude, it indicates that the width of the optical surface 20 scanned by the lidar device gradually increases. At this time, the laser scanning surface 60 moves towards the direction away from the display device 40, and the radar attitude needs to be adjusted in the opposite direction. If the number of the obtained high-reflective point clouds decreases, it indicates that the width of the optical surface 20 scanned by the lidar device gradually decreases. At this time, the laser scanning surface 60 moves towards the direction close to the display device 40, and the radar attitude can continue to be adjusted in this direction.

[0071] In some embodiments, the optical surface 20 is a light-absorbing material, and the light intensity of the reflected light of the optical surface 20 is less than that of the surrounding environment. For example, the optical surface 20 is a light-absorbing material sticker.

[0072] When the laser scanning surface 60 of the lidar device 50 scans the optical surface 20, based on the light-absorbing characteristic of the optical surface 20, the lidar device 50 can obtain a number of low-reflective point clouds reflected by the optical surface 20. The surrounding environment cannot cause the laser beam to reflect to form a low-reflective point cloud.

[0073] When the width of the optical surface 20 increases along the direction close to the screen of the display device 40, if the number of points of the low-reflection point cloud obtained increases during the adjustment of the radar posture, it indicates that the width of the optical surface 20 scanned by the laser radar device gradually increases. At this time, the laser scanning surface 60 moves towards the direction away from the display device 40, and the radar posture needs to be adjusted in the opposite direction. If the number of points of the low-reflection point cloud obtained decreases, it indicates that the width of the optical surface 20 scanned by the laser radar device gradually decreases. At this time, the laser scanning surface 60 moves towards the direction close to the display device 40, and the radar posture can continue to be adjusted in this direction.

[0074] When the width of the optical surface 20 decreases along the direction close to the screen of the display device 40, if the number of points of the low-reflection point cloud obtained increases during the adjustment of the radar posture, it indicates that the width of the optical surface 20 scanned by the laser radar device gradually increases. At this time, the laser scanning surface 60 moves towards the direction away from the display device 40, and the radar posture needs to be adjusted in the opposite direction. If the number of points of the low-reflection point cloud obtained decreases, it indicates that the width of the optical surface 20 scanned by the laser radar device gradually decreases. At this time, the laser scanning surface 60 moves towards the direction close to the display device 40, and the radar posture can continue to be adjusted in this direction.

[0075] As shown in FIGS. 1-3, in some embodiments, the support 10 comprises a mounting portion 110. The mounting portion 110 is connected with the panel 30, and extends away from the surface of the display device 40. The panel 30 extends in a direction perpendicular to the surface of the display device 40.

[0076] It can be understood that the mounting portion 110 can support the panel 30 to prevent the panel 30 and / or the optical surface 20 from being deformed and other defects, so that the adjustment device cannot accurately adjust the posture of the laser radar device 50.

[0077] In some embodiments, the support 10 and the mounting portion 110 can be integrally formed. Specifically, the integrally formed support 10 and the mounting portion 110 can be manufactured by 3D printing. When the support 10 is bonded to the display device 40, double-sided tape can be attached to the support 10. When the support 10 is magnetically connected to the display device 40, a magnetic part mounting groove needs to be reserved during the 3D printing process.

[0078] As shown in FIG. 5, in some embodiments, a plurality of material-removing holes 330 are formed on the panel 30, and a reinforcing rib 340 is formed between each adjacent two material-removing holes 330.

[0079] Based on the design of the material-removing holes 330, the material consumption and weight of the panel 30 can be reduced. Therefore, the manufacturing cost is saved, and the panel 30 is easy to take, place and fix.

[0080] The reinforcing rib 340 formed by each two adjacent material-removing holes 330 can structurally reinforce the panel 30, so as to improve the strength of the panel 30 and the supporting effect of the panel 30 on the optical surface 20, and prevent the optical surface 20 from being deformed. Meanwhile, the reinforcing rib 340 can also prevent the panel 30 from being deformed during storage, transportation and use, so as to affect the flatness of the high-reflectivity material sticker and cause the posture adjustment accuracy of the lidar device 50 to decrease.

[0081] For example, the material-removing hole 330 is a square hole, and a plurality of material-removing holes 330 can form a reinforcing rib 340 in the shape of a cross, so as to structurally reinforce the panel 30 in the length direction and the width direction.

[0082] The plurality of material-removing holes 330 can divide the panel 30 into the reinforcing rib 340 and a frame. The width of the frame can be greater than the width of the reinforcing rib 340.

[0083] Please continue to refer to FIG. 5. In some embodiments, a marking piece 370 is arranged in at least one of the material-removing holes 330, and the marking piece 370 is used to divide the panel 30 into the mounting area 310 and the non-mounting area 320.

[0084] It can be understood that the position of the marking piece 370 is the range closest to the display device 40 from the optical surface 20. For example, the optical surface 20 is a high-reflectivity material sticker, and the high-reflectivity sticker can be cut based on the position of the marking piece 370, so that the high-reflectivity sticker can completely cover the mounting area 310 and leave a gap with the display device 40 in the non-mounting area 320.

[0085] The marking piece 370 is located in the material-removing hole 330 close to the display device 40. The marking piece 370 extends in a direction perpendicular to the display device 40. The two ends of the marking piece 370 are integrally formed on the reinforcing rib 340.

[0086] Meanwhile, based on the design of the marking piece 370, the gap width between each device and the display device 40 can be consistent, so as to ensure the consistency of the laser scanning surface 60 after the radar posture adjustment.

[0087] As shown in FIG. 3, in some embodiments, the side of the panel 30 facing the mounting portion 110 is configured with a first connecting piece 70, and the side of the mounting portion 110 facing the panel 30 is configured with a second connecting piece 80. The first connecting piece 70 and the second connecting piece 80 are slidably connected in a direction perpendicular to the surface of the display device 40.

[0088] Based on the sliding connection of the first connecting piece 70 and the second connecting piece 80, the panel 30 can be relatively slid with the mounting portion 110. Since the sliding direction of the first connecting piece 70 and the second connecting piece 80 is perpendicular to the display device 40, when the support 10 is fixed to the display device 40, the relative distance between the panel 30 and the display device 40 can be adjusted by the relative sliding of the first connecting piece 70 and the second connecting piece 80.

[0089] It can be understood that when the support 10 is fixed to the surface of the display device 40, the panel 30 can be adjusted to a suitable position by sliding along the mounting portion 110, which is beneficial to the accurate correction of the radar posture.

[0090] When the support 10 is fixed to the screen, and the frame of the display device 40 protrudes from the screen, the panel 30 can be slid away from the display device 40 and spaced apart from the display device 40 by a frame thickness, so as to prevent the frame from interfering with the laser scanning surface 60.

[0091] Please continue to refer to FIG. 4 and FIG. 6. In some embodiments, one of the first connecting piece 70 and the second connecting piece 80 is a sliding groove 120, and the other is a sliding block 350, which is slidably installed in the sliding groove 120.

[0092] Based on the sliding assembly of the sliding groove 120 and the sliding block 350, the sliding connection between the panel 30 and the mounting portion 110 is realized. It can be understood that the sliding groove 120 extends in a direction perpendicular to the display device 40, and the sliding block 350 also extends in a direction perpendicular to the display device 40.

[0093] For example, the first connecting piece 70 is the sliding groove 120, and the second connecting piece is the sliding block 350.

[0094] For example, the first connecting piece 70 is the sliding block 350, and the second connecting piece 80 is the sliding groove 120.

[0095] As shown in FIG. 6, in some embodiments, along the direction from the panel 30 to the mounting portion 110, the sliding block 350 includes a first equal-width section 351, a gradually expanding section 352 and a second equal-width section 353 connected in sequence, and the shape of the sliding groove 120 is matched with the shape of the sliding block 350.

[0096] Based on the structural design of the sliding block 350 being the first equal-width section 351, the gradually expanding section 352 and the second equal-width section 353, the 3D printing forming of the sliding block 350 is facilitated. Compared with the I-shaped sliding block 350, the I-shaped sliding block 350 needs to generate support in the process of 3D printing forming, which causes material waste and low efficiency. In the sliding block 350 structure in the present scheme, the slope of the gradually expanding section 352 can be gradually stacked from bottom to top, so that in the process of 3D printing forming, no support needs to be generated, which can save printing materials, shorten printing time and improve efficiency.

[0097] The shape of the sliding groove 120 is the same as that of the sliding block 350 to realize the mutual assembly between the sliding groove 120 and the sliding block 350. The sliding groove 120 can reliably wrap the sliding block 350, ensuring reliable connection between the two. In addition, the sliding groove 120 can also not produce support during 3D printing molding, which can save printing materials, shorten printing time, and improve efficiency.

[0098] Please continue to refer to FIG. 4 and FIG. 6. In some embodiments, the first connecting piece 70 is the sliding block 350, and the second connecting piece 80 is the sliding groove 120. The sliding groove 120 extends from the mounting portion 110 to the support 10 and penetrates the support 10.

[0099] It can be understood that, based on the extension of the sliding groove 120 to the support 10 and the penetration of the support 10, when the sliding adjustment panel 30 is adjusted, the panel 30 can be attached to the display device 40. It can be seen that, if the double-sided adhesive tape has a large thickness, resulting in a wide gap between the support 10 and the display device 40, the sliding range of the panel 30 can be extended by sliding part of the sliding block 350 out of the sliding groove 120, and the accurate adjustment of the radar posture is facilitated.

[0100] In some embodiments, the side of the panel 30 facing the mounting portion 110 is also configured with a reinforcing piece 360. One end of the reinforcing piece 360 is connected with the sliding block 350, and the other end of the reinforcing piece 360 extends away from the display device 40.

[0101] Based on the configuration of the reinforcing piece 360 extending in the direction perpendicular to the display device 40 on the panel 30, the reinforcing piece 360 can structurally reinforce the panel 30 in the direction perpendicular to the display device 40. Based on the configuration of the sliding block 350 on the bottom of the panel 30, the sliding block 350 and the reinforcing piece 360 can prevent the panel 30 from bending, folding, and other phenomena, to ensure the flatness of the optical surface 20.

[0102] At the same time, the reinforcing piece 360 and the sliding block 350 can also prevent the panel 30 from deforming during storage, transportation and use, which affects the flatness of the high-reflective material sticker and causes the posture adjustment accuracy of the laser radar device 50 to decrease.

[0103] As shown in FIG. 13 to FIG. 16, in some embodiments, the panel 30, the mounting portion 110 and the support 10 are integrally formed.

[0104] In this embodiment, the panel 30, the mounting portion 110 and the support 10 are integrally formed. During production, a mold can be designed based on the shapes of the three, and after the mold is opened, the device can be mass-produced according to the mold. Thus, the processing and molding of the device can be facilitated, and the production efficiency can be improved.

[0105] Wherein, on the side close to the display device 40, the panel 30 is arranged coplanar with the support 10. When the support 10 is attached to the display device 40, the panel 30 can also be attached to the display device 40, ensuring the accuracy and reliability of the radar attitude correction.

[0106] As shown in FIG. 13 and FIG. 14, the optical surface 20 is also attached to the upper surface of the panel 30. In the embodiment of one-piece forming, the panel 30 can also have a mounting area 310 and a non-mounting area 320 along the direction perpendicular to the display device 40. The non-mounting area 320 is arranged close to the support 10. The optical surface 20 can also be arranged in the mounting area 310, and the reflected light intensity of the optical surface 20 is different from that of the non-mounting area 320. Thus, as the radar attitude of the laser radar device 50 is continuously corrected, the laser scanning surface 60 will gradually approach the display device 40. When the laser scanning surface 60 moves from the mounting area 310 to the non-mounting area 320, the number of point clouds received by the laser radar device 50 will suddenly change. Thus, the end time of the radar attitude correction can be known, and over-adjustment phenomenon can be prevented.

[0107] As shown in FIG. 15 and FIG. 16, the height of the mounting portion 110 decreases along the direction away from the display device 40. Based on the shape design of the mounting portion 110, on the one hand, the function of saving raw materials can be achieved, and on the other hand, the demolding of the one-piece formed panel 30, mounting portion 110 and support 10 can be facilitated.

[0108] For example, the side of the mounting portion 110 away from the panel 30 is a bevel that gradually approaches the panel 30, so as to form a right triangle-shaped mounting portion 110. For example, the side of the mounting portion 110 away from the panel 30 can also be arranged as an arc surface that gradually approaches the panel 30. Wherein, it is only necessary to ensure that the mounting portion 110 can play the role of supporting the panel 30, and the shape thereof can be reasonably selected based on different use scenarios, and the embodiments of the present application do not limit the shape of the mounting portion 110.

[0109] As shown in FIG. 15, the number of mounting portions 110 can be two. The two mounting portions 110 are arranged at intervals. The support 10 can be fixed to the display device 40 by a clamp, and the area between the two mounting portions 110 can be used as a clamping area of the clamp. It can be understood that by arranging two mounting portions 110 at intervals, on the one hand, a better supporting effect can be achieved on the panel 30, and on the other hand, sufficient width can be reserved on the support 10 to facilitate the installation of the clamp. In the embodiment, the mounting portion 110 can also be attached to the display device 40 by double-sided adhesive tape.

[0110] As shown in FIG. 16, the number of the mounting portion 110 can be set to one. The one mounting portion 110 can be located at a middle position of the panel 30. At this time, the mounting portion 110 can be adhered to the display device 40 by double-sided adhesive tape. Of course, in the present embodiment, the mounting portion 110 can also be fixed to the display device 40 by a clamp. Specifically, the areas of the support 10 on both sides of the mounting portion 110 can serve as clamping areas of the clamp. At this time, the clamping areas on the support 10 can be ensured to be sufficient for mounting the clamp based on the width design of the support 10.

[0111] As shown in FIG. 4, in some embodiments, the support 10 is a T-shaped plate including a horizontal plate and a vertical plate arranged coplanarly, wherein the mounting portion 110 is connected perpendicularly to the horizontal plate or the vertical plate.

[0112] The horizontal plate and the vertical plate arranged coplanarly can make the support 10 have a larger adhesive area with the display device 40, facilitating reliable fixation of the support 10. And the mounting portion 110 being connected perpendicularly to the horizontal plate or the vertical plate can make the support 10 be subjected to both compression and tension when the panel 30 and the optical surface 20 are fixed. In combination with the shapes of the sliding block 350 and the sliding groove 120 described above, the support 10 can have two installation postures. The first installation posture is that, as shown in FIG. 12, the support 10 is installed in a right T shape at a position close to the bottom of the screen. At this time, the screen of the display device 40 is arranged vertically, and the panel 30 and the optical surface 20 are horizontally installed at the front side of the screen. The second installation posture is that, as shown in FIG. 12, the support 10 is installed at a position close to the side edge of the screen. In the second installation posture, two supports 10 are arranged, and the two supports 10 are respectively located at positions close to the left and right sides of the screen. At this time, the screen of the display device 40 is arranged vertically, and the panel 30 and the optical surface 20 are vertically installed at the front side of the screen, and the optical surfaces 20 located at the left and right sides are arranged oppositely.

[0113] In the first installation posture, the support 10, the panel 30 and the optical surface 20 can cooperate to adjust the distance between the laser scanning surface 60 of the lidar device 50 and the screen. In the second installation posture, the support 10, the panel 30 and the optical surface 20 can cooperate to adjust whether the laser scanning surface 60 of the lidar device 50 is left-right symmetrical about the display device 40. Based on the cooperation of the two adjustment modes, the laser scanning surface 60 can be reasonably arranged at the front side of the display device 40.

[0114] Embodiment Two

[0115] The present embodiment provides a

[0116] An adjustment system for the posture of a laser radar device. The adjustment system comprises a display device 40, a laser radar device 50, and at least three adjustment devices for adjusting the posture of the laser radar device 50. Each of the at least three adjustment devices is provided with an optical surface 20. The width of the optical surface 20 increases or decreases in a direction perpendicular to the surface of the display device 40. The laser radar device 50 is arranged at the upper end of the display device 40, and is configured to emit and receive light. At least one adjustment device is arranged at the lower end of the display device 40 relative to the laser radar device 50 in a first direction, and at least two adjustment devices are arranged at the two sides of the display device 40 in a second direction. The first direction is perpendicular to the second direction. The laser radar device 50 is configured to emit light for obtaining point cloud data of the at least three adjustment devices. The optical surfaces 20 of the three adjustment devices are configured to reflect the light emitted by the laser radar device 50 after receiving the light. The laser radar device 50 is further configured to adjust its posture based on the change in light intensity of the light reflected by each optical surface 20.

[0117] In some embodiments, the device is assembled on the display device 40 after the laser radar device 50 is installed on the display device 40. The emitted light (laser beam) of the laser radar device 50 is processed by the optical surface 20. Due to the increase or decrease in the width of the optical surface 20 in a direction perpendicular to the screen of the display device 40, the number of point clouds obtained by the laser radar device 50 based on the reflected light of different widths on the optical surface 20 is different. That is, based on the shape of the optical surface 20, the reflected light received by the laser radar device 50 during radar posture adjustment changes regularly, and the number of point clouds obtained based on the reflected light changes regularly. Based on the change result, it can be known whether the radar posture adjustment of the laser radar device 50 is correct. And based on the correct adjustment direction for subsequent adjustment, so that the laser beam of the laser radar device 50 is as close as possible to the display device 40, and the accuracy of touch interaction is improved.

[0118] Specifically, by installing at least three adjustment devices on the display device 40, whether the adjustment direction of the posture of the laser radar device 50 is correct is determined based on the regular change of the reflected light by the optical surface 20 of the adjustment device. It can include left-right direction adjustment to make the laser scanning surface 60 parallel to the screen of the display device 40. It also includes front-back direction adjustment to make the laser scanning surface 60 close to the screen of the display device 40.

[0119] At least two adjusting devices arranged on two sides of the display device 40 relative to the second direction are used to adjust the posture of the laser radar device 50 so that the laser scanning surface 60 is parallel to the screen of the display device 40. At least one adjusting device arranged at the lower end of the display device 40 relative to the laser radar device 50 is used to adjust the posture of the laser radar device 50 so that the laser scanning surface 60 is close to the screen of the display device 40.

[0120] Based on the laser radar device 50 being configured to emit and receive light rays, the laser radar device 50 at least has a laser emitter and a laser receiver to realize the functions of emitting and receiving light rays.

[0121] The optical surface 20 extends in a direction perpendicular to the display device 40. In addition, the width of the optical surface 20 increases or decreases in a direction perpendicular to the screen of the display device 40. The width of the optical surface 20 can be identified according to the conical laser scanning surface 60 formed by the laser radar device 50. When the radar posture of the laser radar device 50 is adjusted, the laser scanning surface 60 moves, and the width of the identified optical surface 20 changes, so that the adjustment direction of the radar posture is determined based on the change rule. Thus, the laser radar device 50 can continue to adjust its posture in a regular change.

[0122] The optical surface 20 in the embodiments of the present application refers to an optical surface that can reflect or absorb light rays. The reflection ability of the optical surface 20 to light rays is different from the reflection ability of the surrounding environment of the display device 40. Thus, the light intensity of the reflected light rays of the optical surface 20 is different from the light intensity of the reflected light rays of the surrounding environment of the display device 40, and the laser radar device 50 can identify which reflected light rays are the reflected light rays of the optical surface 20. For example, the optical surface 20 can be made of a highly reflective material, and the light intensity of the reflected light rays of the optical surface 20 is greater than the light intensity of the reflected light rays of the surrounding environment of the display device 40. For example, the optical surface 20 can be made of an optical absorption material, and the light intensity of the reflected light rays of the optical surface 20 is less than the light intensity of the reflected light rays of the surrounding environment of the display device 40.

[0123] In some embodiments, the laser radar device 50 further adjusts its posture based on the change of the light intensity of the light rays reflected by each optical surface 20, specifically including:

[0124] The laser radar device 50 is specifically configured to obtain first point cloud data generated on the adjusting device arranged at the lower end of the display device 40, so that the adjusting system adjusts the first vertical distance between the laser scanning surface of the laser radar device 50 and the screen of the display device 40 to be within a first preset distance range based on the first point cloud data, and forms a first posture of the laser radar device 50.

[0125] The laser radar device 50 in the first posture is specifically configured to obtain second point cloud data generated by two adjusting devices arranged on both sides of the display device 40, so that the adjusting system adjusts the laser scanning surface of the laser radar device 50 to be parallel to the screen of the display device 40 according to the second point cloud data, and forms a second posture of the laser radar device 50.

[0126] The laser radar device 50 in the second posture is specifically configured to obtain third point cloud data generated by the adjusting device arranged at the lower end of the display device 40, so that the adjusting system adjusts the second vertical distance between the laser scanning surface of the laser radar device 50 and the screen of the display device 40 to be within a second preset distance range according to the third point cloud data, and forms a third posture of the laser radar device 50; wherein the second vertical distance is less than the first vertical distance.

[0127] It can be understood that after the laser radar device 50 is installed at the upper end of the display device 40, the laser radar device 50 will emit laser beams at a certain angle to form a laser scanning surface 60 in the shape of a cone. After the outgoing light is reflected by the adjusting device arranged at the lower end of the display device 40, the reflected light received by the laser radar device 50 can generate first point cloud data. Based on the regular change in the width of the optical surface 20, the reflected light at each position of the optical surface 20 in the width direction will form first point cloud data with different data amounts. Therefore, the laser radar device 50 can determine the relative position between the laser scanning surface 60 and the screen of the display device 40 through the first point cloud data. Specifically, the laser radar device 50 can determine the first vertical distance between the laser scanning surface 60 and the screen of the display device 40 based on the first point cloud data. Then, the laser radar device 50 adjusts itself to make the first vertical distance within a first preset distance range, and forms a first posture of the laser radar device 50, thereby completing the preliminary adjustment of the laser radar device 50. For example, as shown in FIG. 8, during the above posture adjustment process, the laser scanning surface 60 can be moved from position A to position B.

[0128] After the laser radar device 50 is in the first posture, the laser radar device 50 will continue to emit laser beams, and the two adjusting devices arranged on both sides of the display device 40 will reflect the laser beams respectively. At this time, the laser radar device 50 can receive two groups of reflected light, thereby forming two groups of second point cloud data. Therefore, whether the laser scanning surface 60 is parallel to the display device 40 can be determined through the two groups of second point cloud data. If they are parallel, the current adjustment process is ended; if they are not parallel, the posture of the laser radar device 50 is continuously adjusted until the laser scanning surface 60 is parallel to the display device 40.

[0129] In some embodiments, the two adjusting devices arranged on both sides of the display device 40 are completely identical, and whether the laser scanning surface 60 is parallel to the display device 40 can be determined based on whether the two sets of second point cloud data are equal. In other embodiments of the present application, the optical surfaces 20 of the two adjusting devices arranged on both sides of the display device 40 can also be arranged in a certain ratio. For example, the width ratio of any position of the two optical surfaces 20 in the direction perpendicular to the display device 40 is 1:2. Whether the laser scanning surface 60 is parallel to the display device 40 can be determined based on whether the two sets of second point cloud data are in a 1:2 ratio.

[0130] When the laser radar device 50 is in the second posture, the laser radar device 50 will continue to emit laser beams, and the reflected light received by the laser radar device 50 after being reflected by the adjusting device located at the lower end of the display device 40 can generate third point cloud data. Based on the regular change in the width of the optical surface 20, the reflected light at each position of the optical surface 20 in the width direction will form third point cloud data with different data quantities. Therefore, the laser radar device 50 can determine the relative position between the laser scanning surface 60 and the screen of the display device 40 based on the first point cloud data. Specifically, the laser radar device 50 can determine the second vertical distance between the laser scanning surface 60 and the screen of the display device 40 based on the third point cloud data. Then, the laser radar device 50 adjusts itself to make the second vertical distance within the second preset distance, thereby forming a third posture of the laser radar device 50, and thus completing the posture adjustment of the laser radar device 50. For example, as shown in FIG. 8, during the above posture adjustment, the laser scanning surface 60 can be moved from position B to position C.

[0131] In the embodiments of the present application, the radar posture adjustment is specifically the adjustment of the emission angle of the laser emitter of the laser radar device 50. Based on the use of the device to assist in adjusting the emission angle of the laser emitter, the laser scanning surface 60 of the laser radar device 50 can be adjusted from the scanning position shown in FIG. 10 to the scanning position shown in FIG. 11. This enables the laser scanning surface 60 to be close to the display device 40, thereby improving the accuracy of touch interaction.

[0132] It can be understood that the adjusting device in the embodiments of the present application includes a support 10, a panel 30, and an optical surface 20. The support 10 is used to contact the surface of the display device 40, so that the optical surface 20 forms a right angle with the surface of the display device 40. The panel 30 is connected perpendicularly to the support 10, and the optical surface 20 is arranged on the panel 30. The optical surface 20 is used to receive the light emitted by the laser radar device 50. In the direction perpendicular to the surface of the display device 40, the width of the optical surface 20 increases or decreases, so that after the optical surface 20 receives the light reflected by the laser radar device 50, the reflected light reflected to the laser radar device 50 has different light intensities.

[0133] In a direction perpendicular to the surface of the display device 40, the panel 30 has a mounting area 310 and a non-mounting area 320, the non-mounting area 320 is arranged close to the support 10, wherein the optical surface 20 is arranged at the mounting area 310, and the reflected light of the optical surface 20 is different in light intensity from the reflected light of the non-mounting area 320.

[0134] The optical surface is a reflective material, and the light intensity of the reflected light of the optical surface 20 is greater than that of the reflected light of the surrounding environment in which the display device is located. Alternatively, the optical surface is an absorptive material, and the light intensity of the reflected light of the optical surface 20 is less than that of the reflected light of the surrounding environment in which the display device is located.

[0136] A plurality of material-removing holes 330 are formed on the panel 30, and a reinforcing rib 340 is formed between each two adjacent material-removing holes 330.

[0137] A marking member 370 is arranged in at least one of the material-removing holes 330, and the marking member 370 is used to divide the panel 30 into the mounting area 310 and the non-mounting area 320.

[0138] A first connecting member 70 is arranged on the side of the panel 30 facing the mounting portion 110, a second connecting member 80 is arranged on the side of the mounting portion 110 facing the panel 30, and the first connecting member 70 and the second connecting member 80 are slidably connected in a direction perpendicular to the surface of the display device 40.

[0139] One of the first connecting member 70 and the second connecting member 80 is a sliding groove 120, and the other is a sliding block 350, the sliding block 350 is slidably arranged in the sliding groove 120, and the sliding block 350 comprises a first equal-width section 351, a gradually expanding section 352 and a second equal-width section 353 connected in sequence in a direction in which the panel 30 is arranged towards the mounting portion 110, and the shape of the sliding groove 120 is matched with the shape of the sliding block 350.

[0140] The first connecting member 70 is the sliding block 350, and the second connecting member 80 is the sliding groove 120, wherein the sliding groove 120 extends from the mounting portion 110 to the support 10 and penetrates through the support 10.
