[0028] See Figure 1 and Figure 4 As shown, the lens bracket includes a bracket body 100 and a connecting mechanism 200. The connecting mechanism 200 is disposed on the side of the bracket body 100. Different bracket bodies 100 are connected by the connecting mechanism 200 to splice together to form a lens module.

[0029] The lens holder provided by this utility model connects two adjacent holder bodies 100 by setting the connecting mechanism 200 on them, thus forming a complete lens module. Users can flexibly increase or decrease the number of holder bodies 100 according to actual lighting needs, freely combining them into modules of different lengths and sizes, exhibiting high structural flexibility. Furthermore, by installing different lenses 120 on each holder body 100, lens modules with different focal lengths and lighting angles can be easily combined. This modular design effectively avoids the need to create a new integrated lens mold for each angle requirement, significantly reducing the number of molds required for traditional lenses 120 and effectively lowering production costs. Compared to existing fixed-structure integrated lenses, the combined lens holder lighting solution of this utility model is more flexible, and the reusability of individual holder bodies 100 and lenses 120 is higher, greatly improving the product's reusability.

[0030] In one embodiment of this utility model, see reference Figure 1 , Figure 5 and Figure 6 As shown, the support body 100 is a cuboid, with a sidewall on each of its top and bottom sides, and a sidewall on each of its left and right sides, each sidewall being a plane. Designing the support body 100 as a cuboid facilitates manufacturing, stacking, and precise positioning and alignment during assembly.

[0031] In one embodiment of this utility model, such as Figure 4 As shown, multiple lens supports are arranged linearly. Based on this arrangement, only connecting mechanisms 200 need to be set on the left and right sides of the support body 100. The connecting mechanisms 200 are used to splice two adjacent support bodies 100 to form a linear lens module, realizing the free expansion of the module length. It is possible to flexibly customize linear light source products of different lengths according to actual lighting needs.

[0032] In another embodiment of this utility model, see Figure 5 As shown, multiple lens supports are arranged in an array, allowing for flexible assembly to form a large-area light source. This meets the needs of applications requiring uniform lighting over a wide area, greatly expanding the product's application range. To achieve this array arrangement, connecting mechanisms 200 are provided on the left and right sides, as well as the top and bottom sides of the support body 100, ensuring a stable and reliable mechanical connection between the support bodies 100 in both vertical directions. Furthermore, the connecting mechanisms 200 on the left and right sides are designed with different structures, and the connecting mechanisms 200 on the top and bottom sides are also designed with different structures.

[0033] In one embodiment of this utility model, see reference Figure 4 As shown, the connecting mechanism 200 includes a protrusion 210 and / or a slot 220. The protrusion 210 engages with the slot 220 of another lens bracket, and the slot 220 engages with the protrusion 210 of another lens bracket. The positions of the slot 220 of one lens bracket and the protrusion 210 of another lens bracket are one-to-one. During assembly, the protrusion 210 and the slot 220 engage, making the assembly process extremely convenient and efficient. Operators do not need any tools; they only need to align the two bracket bodies 100 and apply slight pressure to achieve a secure lock, significantly improving assembly efficiency. Simultaneously, this engagement method also greatly facilitates the disassembly of the bracket bodies 100. When it is necessary to replace a module, perform maintenance, or reconfigure the lens module, they can be easily separated, thereby significantly improving the maintainability and reusability of the product, extending the overall product lifecycle, and reducing long-term operating costs.

[0034] In one embodiment of this utility model, see reference Figure 1 and Figure 4 As shown, the protrusion 210 includes a connecting portion 211 and a snap-fit ​​portion 212. The connecting portion 211 extends along the thickness direction of the support body 100, and one side of the connecting portion 211 is connected to the support body 100, providing stable support for the entire connecting mechanism 200. The snap-fit ​​portion 212 extends along the thickness direction of the support body 100 and is connected to the other side of the connecting portion 211. The cross-sectional width of the snap-fit ​​portion 212 is greater than the cross-sectional width of the connecting portion 211, thereby forming a step between the connecting portion 211 and the snap-fit ​​portion 212. This ensures that when the snap-fit ​​portion 212 is engaged in the slot body 221, it is blocked by the limiting structure and cannot slide out or detach from the slot 220. This connection method improves the reliability and stability of the connection and effectively prevents the module from loosening or disintegrating under vibration or accidental stress.

[0035] Preferably, the connecting part 211, the snap-fit ​​part 212 and the bracket body 100 are designed as a single piece to simplify the production process and reduce manufacturing costs.

[0036] It should be noted that the cross-sectional width in this application refers to the dimension of the snap-fit ​​portion 212 and the connecting portion 211 in the direction parallel to the side wall of the bracket body 100, i.e. Figure 4 The dimension indicated by the middle arrow A is in the vertical direction. The cross-sectional thickness refers to the dimension perpendicular to the side wall direction of the main support body 100, i.e. Figure 4 The dimension in the left-right direction indicated by the middle arrow B.

[0037] In one embodiment of this utility model, see reference Figure 1 and Figure 3 As shown, the card slot body 221 extends along the thickness direction of the bracket body 100. In this embodiment, the length of the card slot body 221 is equal to the thickness of the bracket body 100, so as to provide a sufficiently long accommodating space for the snap-fit ​​part 212, ensuring the stability of the connection and the contact area. At the same time, the cross-sectional shape of the card slot body 221 is adapted to the cross-sectional shape of the snap-fit ​​part 212, thereby ensuring that the snap-fit ​​part 212 cannot wobble in the card slot body 221 after being snapped into it, which greatly improves the structural rigidity of the lens bracket after splicing, as well as the stability of the snap-fit ​​part 212 after being snapped into the card slot body 221.

[0038] A connecting groove 222 is disposed on the surface of the bracket body 100 and communicates with the slot body 221 to form a channel with a "T"-shaped cross-section. The cross-sectional shape of the connecting groove 222 is adapted to the cross-sectional shape of the connecting part 211, so that the thinner connecting part 211 can slide in the connecting groove 222. When the locking part 212 at its end enters the wider slot body 221, the connecting part 211 is restricted in the narrow connecting groove 222, thereby preventing the locking part 212 from coming out laterally from the slot body 221 and ensuring the absolute reliability of the connection.

[0039] In another embodiment of this utility model, the slot 220 is an elastic clip (not shown), which is C-shaped or an open annular shape, and is injection molded to the side wall of the bracket body 100. In this embodiment, the cross-section of the latching part 212 is circular, and the opening width of the clip is smaller than the diameter of the latching part 212. During assembly, simply align the latching part 212 with the opening of the elastic clip and press it firmly. The two side walls of the elastic clip will elastically deform under force, and the opening will temporarily expand, allowing the latching part 212 to enter the interior of the elastic clip. Once the latching part 212 is fully inserted, the two side walls of the elastic clip will immediately elastically rebound, narrowing the opening and firmly holding the latching part 212 inside.

[0040] In another embodiment of this utility model, see Figure 1 As shown, the cross-sectional width of the slot body 221 is greater than the cross-sectional width of the connecting groove 222. When the engaging part 212 engages with the slot body 221, the width of the slot body 221 is sufficient to accommodate the large engaging part 212, while the connecting groove 222 communicating with it is narrow enough to restrict the thinner connecting part 211. This forms a physical limiting step inside the slot 220. The limiting step can effectively resist external pulling force and prevent the engaging part 212 from being pulled out of the narrow connecting groove 222. This forms an extremely stable and reliable mechanical lock, ensuring that adjacent support bodies 100 will not accidentally separate after splicing, greatly enhancing the structural stability and vibration resistance of the entire lens module.

[0041] In one embodiment of this utility model, the slot body 221 extends through the entire bracket body 100, forming ports on both end faces of the bracket body 100. This dual-port design greatly enhances the flexibility and convenience of assembly, allowing the mating snap-fit ​​part 212 to slide into the slot body 221 from either end face of the bracket body 100. Operators do not need to spend time aligning to a specific entry direction; assembly can be completed smoothly from either end, effectively reducing operational complexity and potential rework due to incorrect orientation, thereby significantly improving assembly efficiency.

[0042] In one embodiment of this utility model, see reference Figure 1 and Figure 3 As shown, the length of the connecting groove 222 is less than the length of the slot body 221, meaning that a baffle is provided inside the connecting groove 222; correspondingly, the length of the connecting part 211 is less than the length of the snap-fit ​​part 212. When the snap-fit ​​part 212 slides into place along the inside of the slot body 221, the connecting part 211 abuts against the baffle at the end of the connecting groove 222. The operator can clearly perceive through tactile feedback that the snap-fit ​​part 212 has been installed in place, thus avoiding assembly errors caused by excessive sliding. During this process, the baffle acts as a limit, not only ensuring that the spacing between each bracket body 100 is consistent, but also preventing the snap-fit ​​part 212 from completely sliding out from the other end of the connecting groove 222, greatly simplifying the assembly operation and improving the final dimensional accuracy and reliability.

[0043] In one embodiment of this utility model, a resilient positioning protrusion (not shown) is provided on the inner wall of the slot body 221, and a groove is provided on the corresponding surface of the engaging part 212. When the engaging part 212 slides into the slot body 221, the positioning protrusion slides along the surface of the engaging part 212; when the engaging part 212 slides to the preset correct installation position, the positioning protrusion will fit into the groove. The engagement of the positioning protrusion and the groove generates a certain clamping force, effectively preventing the lens module from sliding on its own or shifting due to vibration without external force. Therefore, it also plays the role of precise positioning and preventing slippage, ensuring accurate and reliable assembly.

[0044] In one embodiment of this invention, the thickness of the latching portion 212 gradually increases along its length. As the latching portion 212 slides into the slot body 221, its effective thickness gradually increases with the length it extends into the slot body 221. This increasing thickness creates an increasingly larger interference fit with the inner wall of the slot body 221, thereby generating a continuously increasing positive pressure. This causes the latching portion 212 and the slot body 221 to lock together more and more tightly, forming a strong frictional self-locking effect. This arrangement effectively prevents the lens module from loosening or shifting when subjected to environmental factors such as vibration, impact, or thermal expansion and contraction, thus greatly ensuring the structural stability and optical performance consistency of the product during long-term use.

[0045] In one embodiment of this utility model, the connecting mechanism 200 includes a first connecting surface (not shown) and a second connecting surface (not shown). The first connecting surface is disposed on one of two adjacent support bodies 100, and the second connecting surface is disposed on the other of the two adjacent support bodies 100. The first connecting surface and the second connecting surface are bonded together. By providing the first connecting surface and the second connecting surface on the two adjacent support bodies 100 respectively, a bonding interface is provided for two independent single lenses.

[0046] During assembly, the first and second connecting surfaces are joined by adhesive bonding. Both the first and second connecting surfaces can be planar. Flat surfaces not only facilitate precision machining but also provide a maximized contact area, allowing for uniform application and bonding of the adhesive, thus ensuring reliable bonding quality. Alternatively, one of the first and second connecting surfaces can be convex and the other concave, as long as they can be coupled. This concave-convex mating structure has a self-aligning function, guiding the two support bodies 100° to precise alignment before the adhesive cures, thereby simplifying the assembly positioning process and improving the dimensional accuracy of the final module.

[0047] In one embodiment of this utility model, see reference Figure 1 and Figure 2As shown, the support body 100 has a first end face and a second end face arranged opposite to each other. The first end face has a cavity 110 for mounting a lens 120, and the lens 120 is detachably connected to the cavity 110. Because the lens 120 is detachably connected to the cavity 110, users can easily replace lenses 120 with different focusing angles according to actual supplementary lighting needs, thus quickly transforming the same support body 100 into single lenses with different functions. Based on this, during modular assembly, by freely combining these single lenses with different lenses 120, customized lens modules with complex light distributions and meeting specific scene requirements can be constructed with extreme flexibility, achieving unlimited expansion of optical functions without changing the main hardware.

[0048] In one embodiment of this utility model, see reference Figure 1 and Figure 2 As shown, a positioning protrusion 130 is provided on the inner wall of cavity 110 and one of lens 120, and a positioning groove 140 is provided on the inner wall of cavity 110 and the other of lens 120. The positioning protrusion 130 is embedded in the positioning groove 140. The positioning protrusion 130 and the positioning groove 140 constitute a simple and efficient male-female positioning structure. When the positioning protrusion 130 is embedded in the positioning groove, it can guide lens 120 to fall into the preset position quickly and accurately, which greatly simplifies the installation operation and ensures the basic alignment of the optical center.

[0049] Specifically, the lens 120 has two opposing positioning protrusions 130 on its edge, and two opposing positioning grooves 140 are provided at corresponding positions on the inner wall of the cavity 110, ensuring a one-to-one correspondence between the two. This dual-point positioning design not only provides clear installation direction guidance, but more importantly, it forms a stable two-dimensional planar limit. Compared to single-point positioning, it can more effectively prevent the lens 120 from rotating or shaking within the cavity 110. When the two positioning protrusions 130 are embedded in the two positioning grooves 140 in a one-to-one correspondence, the lens 120 is firmly fixed, ensuring that the lens 120 can maintain its precise optical position even when subjected to external vibration, thereby guaranteeing the stability and consistency of the light output effect of the entire lens module.

[0050] In one embodiment of this utility model, see reference Figure 3 and 4As shown, the second end face of the bracket body 100 is flat, providing a stable and gapless contact reference surface for mounting the bracket body 100 to the light-emitting component (such as a PCB board). The second end face of the bracket body 100 is provided with a mounting port 150 communicating with the cavity 110. The mounting port 150 is a rectangular opening, and its size is adapted to the size of the LED bead. The mounting port 150 is used to mount the LED bead of the light-emitting component. After the LED bead is inserted into the mounting port 150, the light-emitting component and the second end face of the bracket body 100 are bonded together with adhesive, achieving a sealed fit between the bracket body 100 and the light-emitting component. At this time, the lens 120 and the bracket body 100 completely enclose the LED bead, forming an independent micro-optical cavity. This effectively blocks stray light emitted by the LED bead from leaking into the device cavity from this joint, ultimately avoiding interference with other photosensitive elements (such as cameras) inside the device and ensuring the final image quality.

[0051] In one specific embodiment of this utility model, two cameras with the same shape, one camera requires two single lenses and the other requires three single lenses. The lens angle 120 in each single lens is the same. Therefore, it is only necessary to connect the two lens brackets with the protrusion 210 and the slot 220 to form a two-in-one lens module, and connect the three lens brackets with the protrusion 210 and the slot 220 to form a three-in-one lens module, so as to meet the product usage requirements.

[0052] In one specific embodiment of this utility model, for the same camera, two lenses, 2.8mm and 4mm, are required, necessitating two single lenses. The 2.8mm lens requires a lens 120 with a fill light angle of 140°, while the 4mm lens requires a lens 120 with a fill light angle of 110°. When different fixed-focus lenses are used, since the lens 120 is detachably connected to the cavity 110, simply remove the used lens 120 and replace it with another lens 120 to meet the usage requirements.

[0053] In one specific embodiment of this utility model, the camera needs to meet the requirements of 2.8-12mm focal length supplementary lighting, which requires four single lenses. The lens angles 120 of the four single lenses are 140°, 120°, 90° and 90° respectively. The four lens brackets can be connected to the slots 220 through the protrusions 210 to form a four-in-one lens module. The requirements can be met by installing lenses 120 of different angles inside each lens bracket.

[0054] This utility model also provides a camera, which includes the lens bracket described in any of the above embodiments.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
