Description

Technical Field

[0001] This disclosure relates to the technical field of projection equipment, and in particular to a patterned light emission adjustment structure and light emission device. Background Technology

[0002] With the continuous development of projection display technology, patterned projection equipment is increasingly widely used in automotive lighting, entertainment performances, commercial advertising, signage, and other fields. These devices typically project specific patterns onto a target surface to achieve functions such as information transmission, atmosphere creation, or visual enhancement.

[0003] Existing pattern projection equipment has a fixed light output direction or can only be adjusted in one dimension, which limits the position and angle of the projected image and makes it difficult to flexibly adapt to changing installation environments and usage needs. Furthermore, for equipment with pattern projection capabilities, in addition to adjusting the light output direction, the rotation angle calibration of the pattern itself is equally crucial. Even if the equipment's illumination direction is aligned with the target area, the projected pattern may still be skewed due to installation errors or equipment tilt, affecting the visual effect. Moreover, the adjustment mechanism of pattern projection equipment is complex and inconvenient to operate, or can only achieve coarse adjustments in one dimension, making it difficult to simultaneously meet the dual requirements of direction adjustment and precise fine-tuning of the pattern angle.

[0004] For example, prior art document CN202210886166.2 discloses a vehicle-mounted projector. The projection assembly includes a housing that can be detachably fixed inside the car's armrest box. A rotating frame that can swing back and forth is rotatably connected between the left and right side walls of the housing. An optical engine and a projection lens are fixedly connected to the rotating frame, with the projection lens extending out of the housing. A drive assembly for rotating the rotating frame is provided between the rotating frame and the housing. While this solution meets basic lighting or projection needs to a certain extent, its adjustment mechanism is complex and struggles to simultaneously meet the dual requirements of direction adjustment and precise fine-tuning of the pattern angle.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 3 As shown, it is a patterned light emission adjustment structure 10 according to an embodiment of the present invention, including a housing assembly 100, a light emission assembly 200, an adjustment assembly 300 and a support assembly 400. The housing assembly 100 has a receiving cavity 101 formed inside it. The light emission assembly 200 is rotatably disposed in the receiving cavity 101, and the outer circumferential edge of the light emission assembly 200 has a toothed portion 210.

[0023] Further, the adjustment assembly 300 includes an adjustment member 310 and a movable member 320. The movable member 320 is slidably disposed within the receiving cavity 101. The movable member 320 is provided with a transmission part 321 that meshes with the toothed part 210. The adjustment member 310 is connected to the movable member 320. The adjustment member 310 is used to drive the movable member 320 to slide, so that the movable member 320 drives the light-emitting assembly 200 to rotate. The support assembly 400 includes a first adjustment frame 410 and a second adjustment frame 420. The housing assembly 100 is adjustablely disposed on the first adjustment frame 410 along a first direction, and the first adjustment frame 410 is adjustablely disposed on the second adjustment frame 420 along a second direction.

[0024] In this embodiment, the housing assembly 100 is adjusted along a first direction, causing it to swing relative to the first adjustment frame 410, thereby changing the illumination angle of the light-emitting assembly 200 in the first dimension. The first adjustment frame 410 is then adjusted along a second direction, causing it and the housing assembly 100 thereon to swing relative to the second adjustment frame 420, thereby changing the illumination angle of the light-emitting assembly 200 in the second dimension. This constitutes a dual-axis adjustment system, enabling rapid adjustment of the illumination angle of the light-emitting assembly 200. The light emission direction is aligned with the target area; the motion is transmitted to the connected movable part 320 through the adjusting part 310, driving the movable part 320 to slide along a specific path in the receiving cavity 101. During the sliding of the movable part 320, the transmission part 321 of the movable part 320 and the meshing part 210 of the outer edge of the light emission assembly 200 are engaged. The linear sliding of the movable part 320, through the meshing of the teeth, causes the light emission assembly 200 to rotate around its own axis, thereby achieving fine adjustment of the angle of the projected pattern until the pattern is aligned or reaches the required angle.

[0025] The aforementioned patterned light-emitting adjustment structure 10, through a dual-axis adjustment system composed of the first adjustment frame 410 and the second adjustment frame 420, allows the operator to independently adjust the spatial orientation of the housing assembly 100 in two directions, thereby quickly and accurately setting the illumination direction of the light-emitting assembly 200 to adapt to the lighting or projection needs of different scenarios. By driving the movable part 320 to slide through the adjustment member 310, and with the cooperation of the meshing part 210 and the transmission part 321, the rotational motion of the adjustment member 310 is converted into the precise rotation of the light-emitting assembly 200, realizing stepless fine adjustment of the angle of the projected pattern, ensuring that the pattern can be accurately aligned or positioned on the projection surface, and improving the accuracy and aesthetics of the pattern projection. The adjustment assembly 300 is integrated into the receiving cavity 101 of the housing assembly 100, and the sliding part and gear meshing transmission are used to ensure the stability and reliability of the transmission, avoiding the problems of occupying axial space and low rotational accuracy caused by direct rotation adjustment, thereby achieving precise control of the light-emitting angle.

[0026] In one embodiment, the adjusting member 310 and the movable member 320 can be connected by threaded transmission, sliding actuation, or other equivalent transmission methods. In this embodiment, other equivalent transmission methods include, but are not limited to, any equivalent transmission structure that can convert the movement of the adjusting member into linear sliding of the movable member, such as screw and nut transmission, hydraulic transmission, pneumatic transmission, or electromagnetic drive.

[0027] like Figure 3As shown, in one embodiment, the adjusting assembly 300 further includes an elastic element 330 and a sealing element 340. The housing assembly 100 has a through hole 102 communicating with the receiving cavity 101. The adjusting element 310 passes through the through hole 101. The elastic element 330 and the sealing element 340 are both sleeved on the adjusting element 310. The sealing element 340 is disposed in the through hole 102. The two ends of the elastic element 330 elastically abut against the movable element 320 and the inner wall of the housing assembly 100, respectively. In this embodiment, the elastic member 330 provides a continuous elastic preload to the movable member 320, eliminating the meshing gap between the transmission part 321 and the gear part 210; the sealing member 340 prevents external impurities from entering the receiving cavity 101 along the gap between the adjusting member 310 and the housing assembly 100; the elastic member 330 is sleeved on the adjusting member 310 and elastically abuts against the inner walls of the movable member 320 and the housing assembly 100 respectively, so that the elastic member 330 provides a continuous elastic preload to the movable member 320, eliminating the meshing gap between the transmission part 321 and the gear part 210. This further improves the smoothness of the transmission process and the accuracy of angle adjustment, effectively avoiding shaking or backlash caused by gaps; the seal 340 is disposed between the housing assembly 100 and the adjusting member 310, which can effectively isolate external impurities and moisture from entering the receiving cavity 101, ensuring the cleanliness and durability of the internal transmission mechanism, and significantly improving the reliability and environmental adaptability of the overall structure; specifically, the elastic member 330 is at least one of a helical spring, a wave spring, an elastic rubber sleeve, or an elastic bellows; the material of the seal is at least one of rubber or thermoplastic elastomer.

[0028] like Figure 3 As shown, in one embodiment, the adjusting assembly 300 further includes a gasket 350, which is sleeved on the adjusting member. The two ends of the gasket 350 abut against one end of the sealing member 340 and one end of the adjusting member 310, respectively. In this embodiment, if the end of the adjusting member 310 directly contacts the sealing member during rotation, frictional wear may occur due to relative rotation. The gasket 350 protects the sealing member 340 from direct friction and damage, and evenly transmits the axial force applied to the end of the adjusting member 310 to the surface of the sealing member 340.

[0029] like Figure 3As shown, in one embodiment, at least two support blocks 110 protrude from the housing assembly 100, and each of the two support blocks 110 has a sliding hole 1101. The movable member 320 is slidably disposed in the two sliding holes 1101. A stop block 311 is formed on the adjusting member 310, and the stop block 311 is located between the support block 110 and the elastic member 330. In this embodiment, two support blocks 110 are arranged at intervals along the sliding direction of the movable member 320. The sliding holes 1101 provided by the support blocks 1101 together provide dual-point support and guidance for the movable member 320, further ensuring the stability and straightness of the movable member 320 during linear sliding, and effectively preventing the movable member 320 from deflecting or jamming due to uneven force. The stop block 311 formed on the adjusting member 310 is located between the support block 110 and the elastic member 330. The stop block 311 axially limits the installation position of the elastic member 330 to prevent the elastic member 330 from being over-compressed or displaced. The stop block 311 and the support block 110 cooperate to form a limiting structure, which restricts the axial movement range of the adjusting member 310, thereby ensuring the precise controllability of the transmission stroke and improving the reliability and operation feel of the overall adjusting mechanism.

[0030] Furthermore, in one embodiment, the movable member 320 is positioned in an initial state so that the stop block 311 abuts against the support block 110. In this embodiment, the state of the stop block 311 abutting against the support block 110 serves as the starting reference point for the sliding stroke of the movable member 320, providing a repeatable initial position for subsequent adjustments. After establishing the preload and zero-point reference in the initial state, the operator drives the movable member 320 to slide via the adjusting member 310, thereby driving the light-emitting component 200 to rotate precisely around its axis, thus rotating the pattern to a preset angle and achieving fine calibration of the projection pattern direction. When the movable member 320 is in the initial state and the stop block 311 abuts against the support block 110, the elastic member 330 is in a pre-compressed state, and the elastic force it applies to the movable member 320 points towards the support block 110, ensuring stable contact between the stop block 311 and the support block 110, thus ensuring immediate response and backlash-free transmission for angle adjustment.

[0031] Furthermore, in one embodiment, the sliding hole 1101 is a non-circular limiting hole, and the movable member 320 is correspondingly formed with a limiting post that matches the contour of the limiting hole. In this embodiment, the sliding hole 1101 adopts a non-circular cross-section to form a shape-locking fit, effectively preventing the axial rotation of the movable member 320 and ensuring that the transmission part 321 of the movable member 320 and the meshing part 210 of the light-emitting member 230 maintain a precise meshing relationship; the cooperation between the non-circular sliding hole 1101 and the limiting post precisely guides the linear movement of the movable member 320, making the sliding of the movable member 320 smoother.

[0032] like Figure 4As shown, in one embodiment, the first adjusting frame 410 includes a first frame 411, a first screw 412, a first elastic abutment 413, and a first slider 414. The first slider 414 is movably connected to the housing assembly 100. The housing assembly 100 is provided with a swing connection portion 120, which is hinged to the first frame 411. The first screw 412 is threadedly connected to the first slider 414 and is rotatably disposed on the first frame 411. The first elastic abutment 413 is sleeved on the first screw 412. The two ends of the first elastic member 330 abut against the first frame 411 and the housing assembly 100, respectively. In this embodiment, when the first screw 412 is rotated, the first screw 412 drives the first slider 414 to move along its axial direction. Since the first slider 414 is movably connected to the housing assembly 100, and the housing assembly 100 is hinged to the first frame 411 through the swing connection part 120, the movement of the first slider 414 will be converted into the swing of the housing assembly 100 around the hinge axis of the swing connection part 120, thereby realizing the pointing adjustment in the first direction. The first elastic abutment 413 is sleeved on the first screw 412, and its two ends elastically abut against the first frame 411 and the housing assembly 100 respectively. The first elastic abutment 413 provides continuous elastic support for the housing assembly 100, eliminates the thread gap between the screw drives, avoids shaking or backlash during the adjustment process, and at the same time maintains the stable positioning of the housing assembly 100 when the first screw 412 is not driven, thereby improving the accuracy of adjustment and the reliability of the structure.

[0033] like Figure 4As shown, in one embodiment, the second adjusting frame 420 includes a second frame 421, a second screw 422, a second elastic abutment 423, and a second slider 424. The second slider 424 is movably connected to the first frame 411, and the second frame 421 is rotatably disposed on the first frame 411. The second screw 422 is threadedly connected to the second slider 424 and rotatably disposed on the second frame 421. The second elastic abutment 423 is sleeved on the second screw 422, and both ends of the second elastic abutment 423 abut against the first frame 411 and the second frame 421, respectively. In this embodiment, when the second screw 422 is rotated, it drives the second slider 424 to move along its axial direction. Since the second slider 424 is movably connected to the first frame 411, and the second frame 421 is rotatably mounted on the first frame 411, the linear movement of the second slider 424 is efficiently converted into the rotational motion of the first frame 411 relative to the second frame 421, thereby achieving precise pointing adjustment in the second direction. Adjustment via screw drive makes the adjustment stroke controllable and achieves stepless fine-tuning, significantly improving the precision of the direction adjustment. The second elastic abutment 423 is sleeved on the second screw 422 and elastically abuts against the first frame 411 and the second frame 421 respectively. The abutment 423 provides a continuous elastic preload to the first frame 411, eliminating the thread transmission gap between the second screw 422 and the second slider 424. This avoids adjustment backlash or wobbling caused by the gap, ensuring that the first frame 411 can respond instantly with the rotation of the screw during adjustment, achieving precise transmission. The continuous elastic preload applied by the second elastic abutment 423 can lock the relative position between the first frame 411 and the second frame 421, preventing deviation in direction due to external vibration or the weight of the equipment, ensuring the long-term stability of the light output direction. At the same time, the elastic preload can absorb minor mechanical vibrations, making the adjustment feel smoother and more stable, and improving the operating experience.

[0034] like Figure 5 As shown, in one embodiment, the second frame 421 includes a mounting plane 4211 and two support arms 4212. The support arms 4212 are connected to the mounting plane 4211. The two sides of the first frame 411 are rotatably mounted on the two support arms 4212. The mounting plane 4211 has a light-emitting window 4201, which corresponds to the light-emitting direction of the light-emitting component 200. In this embodiment, the double support arms 4212 of the second frame 421 provide stable support for both sides of the first frame 411. The light-emitting window 4201 can be used to embed transparent protective parts, thereby allowing light to pass through smoothly and ensuring light emission efficiency. On the other hand, it forms a physical barrier for the internal structure, preventing foreign objects from entering the receiving cavity 101 from the light-emitting port, thereby improving the protection level of the equipment.

[0035] like Figure 3 As shown, in one embodiment, the housing assembly 100 is provided with a retaining portion 130, the through hole 102 is opened in the retaining portion 130, and one end of the adjusting member 310 is formed with an adjusting end, which is limited to the retaining portion 130. In this embodiment, the size of the adjusting end is larger than the diameter of the through hole 102. The adjusting end cooperates with the enclosure part 130 to restrict the axial movement of the adjusting member 310 and prevent position changes due to vibration or misoperation. The inner wall of the through hole 102 and the outer peripheral surface of the adjusting member 310 form a sliding fit, providing precise support and guidance for the rotational movement of the adjusting member 310. It can be understood that a tool groove is provided on the adjusting end. The adjusting end is flush with or concave with the enclosure part 130 to reduce the risk of rotation of the adjusting member 310 due to accidental contact. The tool groove is used to cooperate with external tools to drive the rotation of the adjusting member 310. By providing a tool groove on the adjusting end, the tool groove can be set in various forms such as cross groove, slotted groove, internal hexagonal groove, plum blossom groove or external hexagonal structure to adapt to the operation requirements of different tools and provide multiple driving methods for the operation of the adjusting member 310.

[0036] like Figure 5 As shown, in one embodiment, the first slider 414 is movably connected to the housing assembly 100 via a floating connection structure, and there is a first allowance of movement between the first slider 414 and the housing assembly 100; and / or, the second slider 424 is movably connected to the first frame 411 via a floating connection structure, and there is a second allowance of movement between the second slider 424 and the first frame 411. In this embodiment, when the first screw 412 or the second screw 422 drives the slider to move, the floating connection structure allows the slider to automatically adjust its posture within the allowance range. The existence of the allowance provides the necessary degrees of freedom for the movement of the first slider 414 and the second slider 424, avoiding problems such as jamming or excessive adjustment resistance caused by overly tight fit.

[0037] Furthermore, in one embodiment, the floating connection structure can be connected using, but is not limited to, a snap-fit ​​floating structure, a sliding groove fitting structure, a pin structure, and a guide post and guide sleeve connection structure. Specifically, the first slider 414 has a first snap-fit ​​portion 4141, and the housing assembly 100 has a corresponding first fastening hole 103. The first snap-fit ​​portion 4141 is fastened within the first fastening hole 103, and there is a movable gap between the first snap-fit ​​portion 4141 and the first fastening hole 103. The second slider 424 has a second snap-fit ​​portion 4241, and the first frame 411 has a corresponding second fastening hole 4101. The second snap-fit ​​portion 4241 is fastened within the second fastening hole 4101, and there is a movable gap between the second snap-fit ​​portion 4241 and the second fastening hole 4101. By specifying the floating connection structure as a snap-fit ​​connection method and combining it with the design of the movable gap, rapid assembly and adaptive sliding between the slider and the corresponding component are achieved.

[0038] Furthermore, in one embodiment, a first movable gap exists between the sidewall of the first latching part 4141 and the inner wall of the first fastening hole 103, and a second movable gap exists between the latching teeth of the first latching part 4141 along the plane of the housing assembly 100 perpendicular to the first fastening hole 103; a third movable gap exists between the sidewall of the second latching part 4241 and the inner wall of the second fastening hole 4101, and a fourth movable gap exists between the latching teeth of the second latching part 4241 along the plane of the first frame 411 perpendicular to the second fastening hole 4101. In this embodiment, by providing movable gaps in both radial and axial directions for the first latching part 4141 and the first fastening hole 103, and the second latching part 4241 and the second fastening hole 4101, a complete two-dimensional floating connection system is constructed. The first movable gap is set between the side wall of the first snap-fit ​​part 4141 and the inner wall of the first snap-fit ​​hole 103. The first movable gap acts in the direction perpendicular to the sliding direction of the first slider 414, providing radial floating space for the first slider 414 during sliding, and avoiding jamming due to excessive tightness. The second movable gap is set in the plane of the snap teeth of the first snap-fit ​​part 4141 and the first snap-fit ​​hole 103 in the direction perpendicular to the housing assembly 100, providing axial floating allowance for the connection of the first snap-fit ​​part 4141. By setting two movable gaps in different directions between the first snap-fit ​​part 4141 and the first snap-fit ​​hole 103, multi-dimensional floating connection and precise guidance are achieved. The third movable gap is set between the side wall of the second snap-fit ​​part 4241 and the inner wall of the second snap-fit ​​hole 4101. The third movable gap acts in the direction perpendicular to the sliding direction of the second slider 424, providing radial floating space for the second slider 424 during sliding, and avoiding jamming due to excessive tightness. The third movable gap is set on the plane perpendicular to the snap-fit ​​teeth of the second snap-fit ​​part 4241 and the second snap-fit ​​hole 4101, providing axial floating allowance for the connection of the second snap-fit ​​part 4241. By setting two movable gaps in different directions between the second snap-fit ​​part 4241 and the second snap-fit ​​hole 4101, multi-dimensional floating connection and precise guidance are achieved.

[0039] Furthermore, in one embodiment, the movable gap between the first slider 414 and the housing assembly 100 is 0.5mm-3mm, and the movable gap between the second slider 424 and the first frame 411 is also 0.5mm-3mm. The movable gap can be, but is not limited to, 0.5mm-3mm, and can be flexibly adjusted by those skilled in the art according to product design. In this embodiment, by limiting the movable gaps between the first slider 414 and the housing assembly 100, and between the second slider 424 and the first frame 411, to the range of 0.5mm to 3mm, a balance between smooth adjustment and structural stability is achieved. This avoids jamming or excessive adjustment resistance due to excessively small gaps, which would affect the operating feel. The gap range effectively limits the radial sway of the slider and prevents the housing assembly 100 or the first adjustment frame 410 from being affected during adjustment due to excessively large gaps, thus ensuring the accuracy and reliability of directional adjustment.

[0040] like Figure 5 As shown, further, in one embodiment, the first adjustment frame 410 and the second adjustment frame 420 are initially tilted to one side, and the light-emitting surface of the housing assembly 100 is initially tilted to the other side. In this embodiment, the first adjustment frame 410 and the second adjustment frame 420 are initially tilted to one side, while the light-emitting surface of the housing assembly 100 is initially tilted to the other side, so that the forward and reverse adjustment strokes of the entire adjustment system are evenly distributed. The initial reverse tilt can serve as a reference zero point for system calibration. In subsequent adjustment processes, whether the light-emitting surface is adjusted upward or downward, the adjustment margin is basically consistent, avoiding the problem of insufficient adjustment stroke in one direction due to initial position offset. The initial setting allows the adjustment mechanism to maintain a reasonable transmission angle at the limit position, avoiding adjustment failure due to motion interference or decreased transmission efficiency.

[0041] like Figure 3 and Figure 6As shown, in one embodiment, the light-emitting assembly 200 includes a shaft assembly 220, a light-emitting element 230, and a control plate 240. The shaft assembly 220 and the control plate 240 are both fixedly installed in the receiving cavity 101. The light-emitting element 230 is rotatably connected to the shaft assembly 220 and electrically connected to the control plate 240. The meshing portion 210 is formed on the circumferential outer edge of the light-emitting element 230. In this embodiment, the light-emitting component 230 and the shaft assembly 220 are fitted with bearings or bushings, so that the light-emitting component 230 rotates smoothly around its own axis when driven by the adjustment component 300, ensuring the smoothness and accuracy of pattern rotation adjustment; through conductive slip rings, flexible circuit boards or contact points, the electrical circuit of the light-emitting component 230 remains conductive when rotating around the shaft assembly 220, thereby ensuring the normal operation of functions such as light source power supply and pattern switching; the control board 240 can be arranged close to the shaft assembly 220, shortening the electrical connection path and reducing the space occupied by the wiring harness; at the same time, the light-emitting component 230 is rotatably connected to the shaft assembly 220, making the entire light-emitting component 200 compact, which helps to reduce the volume of the receiving cavity 101 and achieve miniaturization of the overall structure.

[0042] like Figure 3 As shown, further, in one embodiment, the rotation axis of the light-emitting component 200 is perpendicular to the adjustment direction of the adjusting member 310, and the transmission part 321 of the movable member 320 is disposed on the radial side of the light-emitting component 200, and the sliding direction of the transmission part 321 is parallel to the axial direction of the adjusting member 310. In this embodiment, the rotation axis of the light-emitting component 200 is perpendicular to the adjustment direction of the adjusting member 310, and the sliding direction of the transmission part 321 of the movable member 320 is parallel to the axial direction of the adjusting member 310, forming an orthogonal transmission system. This achieves direction conversion within a limited space, avoiding layout difficulties caused by conflicting transmission directions. By disposing the transmission part 321 of the movable member 320 on the radial side of the light-emitting component 200, the transmission mechanism is arranged close to the outer periphery of the light-emitting component 200, rather than occupying the space at both axial ends of the light-emitting component 200. This side-mounted layout fully utilizes the light-emitting component 200. The radial unused space provides more installation space for other components, which is conducive to the miniaturization and compactness of the overall structure. The axis of the adjustment component 310 is perpendicular to the rotation axis of the light-emitting component 200, which allows the adjustment component 310 to be led out from the side or end of the housing component 100, avoiding spatial interference between the adjustment component 310 and the light-emitting component 230. When multiple independent adjustment functions need to be integrated, the orthogonal transmission layout can effectively avoid motion interference between the adjustment axes, allowing multiple adjustment components 310 to be arranged in layers without interfering with each other, providing a structural basis for the realization of complex adjustment functions.

[0043] like Figure 6As shown, in one embodiment, the housing assembly 100 includes a mounting body 140, a light-emitting panel 150, and a heat dissipation back cover 160. The receiving cavity 101 is formed inside the mounting body 140. The light-emitting panel 150 is connected to the mounting body 140 and has a light-emitting part 151 corresponding to the light-emitting component 200. The heat dissipation back cover 160 is connected to the mounting body 140 and covers the control plate 240. In this embodiment, the support block 110, the swing connection part 120, and the enclosure part 130 are all formed within the mounting body 140. By splitting the housing assembly 100 into a separate structure consisting of the mounting body 140, the light-emitting panel 150, and the heat dissipation back shell 160, the functional zoning and synergistic optimization of optical output, structural support, and heat dissipation management are achieved. The light-emitting panel 150 is independently set and connected to the mounting body 140, with the light-emitting part 151 facing the light-emitting component 200, enabling efficient and accurate projection of light. The control board 240 is a heat source, and the heat dissipation back shell 160 is placed on top of it, increasing the heat dissipation area of ​​the housing and forming an effective heat conduction path. This prevents heat from accumulating in the receiving cavity 101, ensuring that the control board 240 and the light-emitting component 200 operate stably within a suitable temperature range and extending the service life of electronic components.

[0044] like Figure 6 and Figure 7 As shown, in one embodiment, an annular blocking portion 152 is formed on the inner edge of the light-emitting panel 150, and a corresponding blocking groove 1401 is provided on the mounting body 140. The annular blocking portion 152 is correspondingly embedded in the blocking groove 1401. In this embodiment, the engagement of the annular blocking portion 152 and the blocking groove 1401 extends the path for external impurities to enter the receiving cavity 101, increases the contact area and bonding depth between the mounting body 140 and the light-emitting panel 150, and improves the mechanical stability of the overall structure. The engagement relationship between the annular blocking portion 152 and the blocking groove 1401 plays a pre-positioning role during assembly, simplifies the assembly process, and improves assembly efficiency and consistency.

[0045] like Figure 6 and Figure 7As shown, in one embodiment, the inner wall of the blocking groove 1401 is further provided with a snap-fit ​​groove 1402, and the light-emitting panel 150 is correspondingly provided with a snap-fit ​​block 153, which is embedded in the snap-fit ​​groove 1402. In this embodiment, by adding a snap-fit ​​groove 1402 to the inner wall of the blocking groove 1401 and correspondingly setting a snap-fit ​​block 153 on the mounting body 140, secondary locking and positioning enhancement are achieved on the basis of the interlocking of the annular blocking part 152 and the blocking groove 1401. Moreover, the cooperation between the snap-fit ​​block 153 and the snap-fit ​​groove 1402 has the function of preventing foolproof installation. During the assembly process, the snap-fit ​​block 153 can be smoothly inserted into the snap-fit ​​groove 1402 only when the mounting body 140 is aligned in the correct position, thereby avoiding misaligned installation and improving assembly efficiency and consistency. When the housing assembly 100 is subjected to torsional torque, the interlocking structure of the annular blocking part 152 and the blocking groove 1401 mainly bears the radial force, while the cooperation between the snap-fit ​​block 153 and the snap-fit ​​groove 1402 can effectively bear the circumferential force, so that the connection structure has excellent load-bearing capacity in multiple directions.

[0046] like Figure 6 As shown, in one embodiment, the housing assembly 100 further includes a thermally conductive layer 170, which is disposed between the heat dissipation back cover 160 and the control board 240, and the thermally conductive layer 170 makes thermal contact with the heat dissipation back cover 160 and the control board 240 respectively. In this embodiment, there are microscopic unevenness or assembly gaps between the surface of the control board 240 and the heat dissipation back shell 160. The thermally conductive layer 170 fills the interface gaps to reduce contact thermal resistance, ensuring that the heat generated by the control board 240 is efficiently conducted to the heat dissipation back shell 160. The thermally conductive layer 170 has good thermal diffusion performance, which can quickly diffuse the heat in the hot spot area along the planar direction, so that the heat is evenly distributed before being conducted to the heat dissipation back shell 160, avoiding local overheating. The thermally conductive layer 170 also plays an electrical isolation role while conducting heat, preventing short circuits or leakage between the circuits on the control board 240 and the metal heat dissipation back shell 160. The thermally conductive layer 170 has a certain degree of flexibility and elasticity, which can absorb the relative displacement or vibration impact between the control board 240 and the heat dissipation back shell 160.

[0047] like Figure 6As shown, in one embodiment, the housing assembly 100 further includes a sealing frame 180, which is disposed between the heat dissipation back cover 160 and the control board 240. A heat dissipation channel is formed in the middle of the sealing frame 180, and the thermally conductive layer 170 is located within the heat dissipation channel. In this embodiment, the sealing frame 180 serves as a sealing element, isolating the control board 240 area from the external environment to prevent dust and moisture intrusion. The sealing frame 180 maintains the distance between the heat dissipation back cover 160 and the control board 240, preventing deformation of the control board 240 due to excessive pressure. Through the integrated design of the sealing frame 180, the heat dissipation channel, and the thermally conductive layer 170, while ensuring the sealing protection of the control board 240 area, an efficient directional heat dissipation path is constructed, enabling the control board 240 area to achieve both sealing protection and efficient heat dissipation within a limited space.

[0048] This application also provides a light-emitting device, including the patterned light-emitting adjustment structure 10 described in any of the above embodiments. In this embodiment, the light-emitting device integrates the dual-axis adjustment structure of the support assembly 400 and the precision transmission structure of the adjustment assembly 300, allowing the operator to adjust the spatial orientation of the housing assembly 100 along the first and second directions to achieve coarse adjustment and positioning of the illumination direction of the light-emitting assembly 200. By driving the movable part 320 to slide through the adjustment member 310, the light-emitting assembly 200 is precisely rotated around its own axis to achieve fine adjustment of the angle of the projected pattern. This allows the light-emitting device to flexibly adapt to the lighting or projection needs of different scenarios, enabling both directional lighting and pattern projection to be adjusted quickly and accurately. Through the precise cooperation between the meshing part 210 and the transmission part 321, and the continuous pre-tightening force provided by the elastic member 330, the light-emitting assembly 200 rotates without gaps or shaking, ensuring that the pattern can be accurately aligned or positioned on the projection surface.

[0049] In one embodiment, the light-emitting device includes at least one of a pattern projection device, an imaging and projection device, an industrial inspection and measurement device, an optical signal emitting device, and other optical devices that require adjustment of the light-emitting direction and pattern angle.

[0050] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned patterned light-emitting adjustment structure 10, through a dual-axis adjustment system composed of the first adjustment frame 410 and the second adjustment frame 420, allows the operator to independently adjust the spatial orientation of the housing assembly 100 in two directions, thereby quickly and accurately setting the illumination direction of the light-emitting assembly 200 to adapt to the lighting or projection needs of different scenarios. By driving the movable part 320 to slide through the adjustment member 310, and with the cooperation of the meshing part 210 and the transmission part 321, the rotational motion of the adjustment member 310 is converted into the precise rotation of the light-emitting assembly 200, realizing stepless fine adjustment of the angle of the projected pattern, ensuring that the pattern can be accurately aligned or positioned on the projection surface, and improving the accuracy and aesthetics of the pattern projection. The adjustment assembly 300 is integrated into the receiving cavity 101 of the housing assembly 100, and the sliding part and gear meshing transmission are used to ensure the stability and reliability of the transmission, avoiding the problems of occupying axial space and low rotational accuracy caused by direct rotation adjustment, thereby achieving precise control of the light-emitting angle.

[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
