[0002] The lens holder is a holder that can be used to embed a variety of optical devices. When the lens holder of the existing projection equipment needs to install two lenses in different positions, it is necessary to assemble two lens holders of corresponding sizes, such as Figure 1 As shown, the small lens is mounted on a small lens holder, and the large lens is mounted on a large lens holder; the small lens holder and the large lens holder are mated and connected. When this structure is used, the optical path formed by the small and large lenses is affected by the machining and assembly accuracy of the two holders, making it difficult to ensure optical path accuracy. Furthermore, the use of two holders increases the difficulty of component processing, which in turn increases production costs. Utility Model Content

[0003] The purpose of the present utility model is to provide an integrated lens support structure that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, an integrated lens bracket structure is provided, including a frame body, a accommodating cavity is provided in the frame body, a mounting plate is provided in the accommodating cavity, a first mounting position is provided on the inner wall of the accommodating cavity, a second mounting position is provided on the mounting plate, the first mounting position is located on one side of the second mounting position, and the frame body, the mounting plate, the first mounting position and the second mounting position are an integrally formed structure.

[0005] The beneficial effects of the present invention are as follows: by forming the frame and the various structures in the frame into an integrally formed structure, the entire lens holder is an integrated structure. When installing the lens, there is no need to reassemble multiple holders, which improves the processing efficiency of the lens holder and helps reduce the overall cost. At the same time, by providing a first mounting position and a second mounting position, it is convenient to install the lens correspondingly at each mounting position, and the installation of two lenses on one frame is realized. The optical path relationship formed by the lens can be guaranteed, the assembly steps are simplified, the overall processing and assembly process is simplified, and the overall structure is simple.

[0006] In some embodiments, the first mounting position is a mounting step, and a through hole is provided on the mounting plate, forming a second mounting position.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 2 to 4 An integrated lens holder structure includes a frame 1, a receiving cavity 11 is provided in the frame 1, a mounting plate 12 is provided in the receiving cavity 11, a first mounting position 13 is provided on the inner wall of the receiving cavity 11, a second mounting position 14 is provided on the mounting plate 12, and the first mounting position 13 is located on one side of the second mounting position 14. The frame 1, the mounting plate 12, the first mounting position 13 and the second mounting position 14 are an integrally formed structure.

[0021] The first mounting position 13 is a mounting step. A through hole 121 is provided on the mounting plate 12 . The through hole 121 forms the second mounting position 14 . The aperture of the first mounting position 13 is larger than that of the second mounting position 14 .

[0022] When installing the lenses on the lens holder 1, the small lens is mounted on the second mounting position 14, and the large lens is mounted on the first mounting position 13. When installing the small lens, it can be directly opposite the through hole 121. The mounting plate 12, positioned around the periphery of the through hole 121, constrains the small lens's periphery, facilitating its installation in the second mounting position 14. When installing the large lens, it is positioned within the accommodating cavity 11. The first mounting position 13 constrains the large lens's periphery, facilitating its installation in the first mounting position 13.

[0023] A limiting buckle 16 is provided on the mounting plate 12 , and the limiting buckle 16 is located at the periphery of the second mounting position 14 .

[0024] The second mounting position 14 is formed with vertical edges 15 on its outer periphery. These edges 15 are perpendicular to the mounting plate 12, and retaining clips 16 are positioned between adjacent vertical edges 15. The width of the retaining clips 16 is smaller than that of the vertical edges 15. When a lenslet is installed in the second mounting position 14, the vertical edges 15 provide a certain degree of positional retention. The retaining clips 16 are angled toward the through-hole 121, pressing the lenslet firmly and preventing it from falling off after installation.

[0025] In actual use, the limiting buckle 16 may be in other shapes, and can press the small lens toward one side of the through hole 121 to fix the small lens.

[0026] Thus, the small lens is fixed mechanically, which is simple, convenient, and quick to install. It eliminates the need to seal the small lens on the bracket with high-temperature sealant and the glue coating process. Since the small lens works at high temperatures for a long time, the sealant is easily aged and falls off, which seriously affects the service life of the device. Therefore, the mechanical fixing method of the limit buckle 16 is adopted to greatly reduce this risk, indirectly save the use of high-temperature glue, and reduce production costs.

[0027] The sidewall of the frame 1 is provided with a first fixing hole 17, located forward of the first mounting position 13. The first mounting position 13 is located between the first fixing hole 17 and the second mounting position 14. Therefore, after the large lens is properly installed in the first mounting position 13, an external positioning screw is inserted through the first fixing hole 17, pressing the front face of the large lens, securing the large lens in place through the combined action of the positioning screw and the first mounting position 13. There are at least two, and may be three or more, first fixing holes 17, which can be increased or decreased based on specific requirements. The first fixing holes 17 are evenly distributed along the sidewall of the frame 1. This allows large optical components, such as large lenses, to be positioned and locked with minimal locking force. This prevents these heavy components from shifting during use, making them less likely to loosen or slip. This ensures that the optical path relationship of the component remains stable, significantly improving performance reliability. This also reduces the use of high-temperature adhesives and other processes, shortening production cycles and significantly simplifying the overall installation process and improving efficiency.

[0028] In actual use, the distance between the first and second mounting positions can be adjusted during the molding process of the frame 1, thereby adjusting the distance between the two lenses to meet different optical path requirements. The two lenses in the frame 1 are fixed by a mechanical structure, which facilitates the removal and replacement of the corresponding lenses.

[0029] On the other side of the mounting plate 12, a light cup 18 is provided. Light cup 18 has a light hole 181 formed therein, corresponding to through hole 121. The light cup 18 and the mounting plate 12 are integrally formed. To enhance the light-focusing effect of the light cup 18, the light cup 18 is tapered. The size of the light cup 18 can be increased or decreased depending on the size and power of the actual light source assembly.

[0030] In actual use, a reflective cup made of a material with a higher reflectivity can be installed inside the optical cup 18. The upper edge of the reflective cup can be located at the second installation position. The reflective cup can be pressed tightly by the small lens during installation, thereby further improving the projection utilization rate, light collection rate and reflectivity.

[0031] By providing a light cup 18, the large end of the light cup 18 is close to the through hole 121, and the external light-emitting lamp group is installed on the outside of the small end of the light cup 18. The light passes through the through hole 181 and can be converged by the light cup 18 to improve the light collection rate, and then emitted through the lens to meet the use requirements.

[0032] The mounting plate 12 is provided with a second fixing hole 19. Through the second fixing hole 19, an external fixing screw can be conveniently passed through the second fixing hole 19 and then locked and fixed with other structures, thereby facilitating the installation of the entire lens bracket.

[0033] When the light-emitting lamp group on one side of the light cup 18 needs to be replaced with a light-emitting device of different specifications or power, since the two lenses in the frame 1 are fixed by a mechanical structure, after loosening the corresponding screws or structures, taking out the lens, and taking out the fixing screws at the second fixing hole 19, the frame 1 can be taken out to facilitate replacement of related components.

[0034] A wire outlet hole 10 is provided on one side of the bottom end of the frame 1. Therefore, the wire outlet hole 10 can facilitate the wiring of the light-emitting element through the wire outlet hole 10, play a guiding role, facilitate the routing of the wires, avoid the mess of the wires, and improve the simplicity.

[0035] The above are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
