Description

Technical Field

[0001] This invention relates to the field of optical imaging technology, specifically to a split optical lens module and a method for assembling the split modules. Background Technology

[0002] With the rise of the short video and live streaming industry, in recent years, on the one hand, the market has put forward increasingly higher demands for the imaging quality of camera modules, and on the other hand, the market has almost stringent requirements for the small size of camera modules (that is, the smaller the space occupied by the camera module, the better). However, the smaller the space occupied by the camera module, the more difficult it is to improve its imaging quality.

[0003] Currently, as one of the core components of a camera module, the quality of the optical lens and the magnitude of assembly errors directly affect the imaging quality of the camera module. Specifically, traditional optical lenses typically include a lens barrel, multiple lenses located within the lens barrel, and spacers between adjacent lenses. The optical lens is usually fixedly assembled into the lens barrel structure. This fixed structure leads to fixed shooting effects that are difficult to meet the current market demands. To solve the problem of fixed effects, CN109270654A discloses an optical lens that proposes a segmented, split-structure optical lens. The number of lens modules and the guiding or adjusting role of each lens module can be set according to application requirements, which can improve the compatibility of lens products and help optimize and expand the functions of lens products.

[0004] The aforementioned optical lenses have drawbacks. First, they can only be separated into segments, and the optical lenses in each segment are fixedly assembled into the lens barrel using a solidified structure, which cannot truly achieve the separation of optical lenses. Second, the segmented barrels are connected by threads, which cannot adjust the distance between the segments according to the different focal lengths of the different lenses in each segment, which may lead to difficulty in focusing and damage to the image quality. Summary of the Invention

[0005] The purpose of this invention is to provide a split optical lens module to solve the technical problem that the existing technology still uses a solid connection between the various segmented cylinders, which makes it difficult to achieve true separation, and the lack of consideration for the focal length of the optical lens on the connecting side in the connection of the segmented cylinders may lead to the inability to focus.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A split-type optical lens module includes a first split-lens assembly and a second split-lens assembly. The first split-lens assembly includes a first cylinder and a plurality of optical lenses disposed inside the first cylinder. The second split-lens assembly includes a second cylinder and a plurality of optical lenses disposed inside the first cylinder. The first split-lens assembly and the second split-lens assembly are combined and connected by a connecting mechanism disposed on the first cylinder and the second cylinder.

[0008] As a preferred embodiment of the present invention, the connecting mechanism includes multiple connecting rods arranged in a ring along the end face of the first cylinder, one end of which is mounted on the end face of the first cylinder relative to the side of the second cylinder, and a limiting strip mounted on the other end of each connecting rod. The limiting strip has a vertically symmetrical structure about the connecting rod. A connecting groove is provided in a ring along the end face of the second cylinder relative to the side of the first cylinder for the multiple connecting rods to wedge into. The length of the limiting strip is the same as the inner diameter of the cross-section of the connecting groove. The limiting strip slides axially along the connecting groove under the action of external force. An adjustment and positioning mechanism is provided between the limiting strip and the groove wall of the connecting groove. The adjustment and positioning mechanism fixes the sliding position of the limiting strip in the connecting groove.

[0009] As a preferred embodiment of the present invention, the adjusting positioning mechanism includes two mounting holes recessed inward at both ends of the limiting strip. A positioning top bead is provided at the opening of the mounting hole. The positioning top bead is connected to the mounting hole through a linear spring strip located inside the mounting hole. The diameter of the positioning top bead is the same as the cross-sectional diameter of the mounting hole. When the linear spring strip is in its original length state, half of the volume of the positioning top bead is exposed at the front end of the mounting hole opening. Two axial grooves are provided on the wall of the connecting groove for the axial sliding of the exposed part of the positioning top bead in the two mounting holes. Multiple positioning bead holes matching the positioning top bead are arranged linearly on the upper part of the axial grooves. The positioning top bead slides into or out of the positioning bead hole under the action of external force.

[0010] In a preferred embodiment of the present invention, the width of the axial groove is smaller than the diameter of the open portion of the positioning bead hole, and the size of the positioning bead hole is adapted to the size of the exposed portion of the positioning top bead.

[0011] In a preferred embodiment of the present invention, a plurality of strip spring plates are arranged circumferentially on the surface of the connecting rod. One end of each strip spring plate is connected to one end of the connecting rod located at the end face of the first cylinder. The other ends of the strip spring plates are independent of each other and are freely suspended. The other ends of the freely suspended strip spring plates form a planar shape consistent with the cross-sectional plane shape of the connecting groove. The strip spring plates are pushed into the connecting groove or pulled out from the connecting groove under the action of external force.

[0012] In a preferred embodiment of the present invention, both the first and second cylindrical bodies are provided with a plurality of lens holders for placing the optical lenses. The plurality of lens holders are parallel to each other and do not contact each other. The top of each lens holder has a lens placement opening for placing the optical lens. The optical lens placed in the lens holder is fixedly connected to the lens holder by a fastener. The fastener includes a connecting male fastener disposed around the optical lens and a connecting female fastener disposed on the outer wall of the cylindrical body located at both ends of the lens placement opening for the connecting male fastener to engage. The connecting male fastener and the connecting female fastener engage or disengage under the action of external force.

[0013] As a preferred embodiment of the present invention, the lens holder and the connecting buckle are provided with clamping grooves that match the shape of the edge of the optical lens. The two sides of the clamping grooves are located on the two sides of the optical lens and are in contact with the surface of the optical lens. The clamping grooves on the connecting buckle and the lens holder together form an annular structure with the same shape as the edge of the optical lens.

[0014] As a preferred embodiment of the present invention, a method for split assembly of the split optical lens module includes the following steps:

[0015] For S100, depending on the needs of taking photos or achieving photographic effects, select the single or multiple optical lenses to be used;

[0016] S200: Place the optical lens from the lens mounting opening on the first cylinder and the second cylinder onto the lens holder, and fix its position using the mating buckle to form the first split lens assembly and the second split lens assembly.

[0017] S300: The first split lens assembly and the second split lens assembly are connected using a connecting mechanism, and the distance between the first end of the first barrel and the second end of the barrel is adjusted by an adjusting positioning mechanism to meet the optical parameters of the optical lens according to the optical parameter requirements of the optical lens between the end of the first barrel and the front end of the second barrel.

[0018] S400 After shooting, the first and second split lens assemblies are separated, and the optical lenses are gradually removed from the first and second barrels of the first and second split lens assemblies.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention combines optical lens modules using a split structure. Firstly, it employs a first and second split lens assembly as segmented units. Within each of these assemblies, multiple lens mounts are installed in the first and second cylinders to assemble optical lens combinations that produce various effects, adapting to different shooting scenarios. The segmented structure is further divided into individual segments for complete optical lens assembly. A connecting mechanism connects the first and second cylinders. Positioning beads at the opening of the limiting strip at the front end of the connecting rod on the first cylinder slide between multiple positioning bead holes inside the connecting groove on the second cylinder, adjusting the connection distance between the first and second cylinders. This ensures that the focal length of the optical lens at the end of the first cylinder converges onto the optical lens at the front end of the second cylinder, preventing focusing problems. The number of lens modules and the combination of optical lenses within each module can be selected according to application requirements, improving the compatibility and shooting effect of the lens product.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1 As shown, the present invention provides a split optical lens module, including a first split lens assembly 1 and a second split lens assembly 2. The first split lens assembly 1 includes a first barrel 101 and a plurality of optical lenses disposed inside the first barrel 101. The second split lens assembly 2 includes a second barrel 201 and a plurality of optical lenses disposed inside the first barrel 101. The first split lens assembly 1 and the second split lens assembly 2 are combined and connected by a connecting mechanism 3 disposed on the first barrel 101 and the second barrel 201.

[0037] This embodiment divides the traditional one-piece solidified optical lens module into two optical lens modules, namely a first split lens assembly 1 and a second split lens assembly 2, which are connected to form a single structure through a connecting structure. In specific implementation, the optical lens module may only include the first split lens assembly 1 and the second split lens assembly 2, without including other split lens assemblies. Alternatively, in addition to the first split lens assembly 1 and the second split lens assembly 2, the optical lens module may also include several split lens assemblies assembled between the first split lens assembly 1 and the second split lens assembly 2. The number of split lens assemblies disposed between the first split lens assembly 1 and the second split lens assembly 2 can be set according to actual application requirements, such as one, two, or other numbers, all of which are within the protection scope of this invention.

[0038] like Figure 1-3 As shown, in order to further transform the segmented structure into a separate optical lens structure, and to configure the optical lenses in the first cylinder 101 and the second cylinder 201 into a separate structure that can be freely combined according to the desired shooting effect, multiple lens holders 6 for placing optical lenses are provided in both the first cylinder 101 and the second cylinder 201. One or more optical lenses can be inserted into the multiple lens holders 6 and combined to obtain the desired shooting effect, such as filter effect, wide-angle effect, etc. The multiple lens holders 6 are parallel to each other and do not contact each other, keeping the multiple optical lenses placed in the lens holders 6 parallel to each other. The lenses do not touch each other, ensuring that the light remains in a straight line when passing through multiple optical lenses and that each optical lens produces a corresponding lens effect. According to the desired shooting effect, the selected optical lens is placed in the lens holder 6 through a lens mounting opening 7 on the top of the lens holder 6. The optical lens placed in the lens holder 6 is fixedly connected to the lens holder 6 by a docking buckle 8. The docking buckle 8 includes a connecting male buckle 801 located on the periphery of the optical lens and a connecting female buckle 802 located on the outer wall of the cylinder at both ends of the lens mounting opening 7 for the connecting male buckle 801 to fasten. The connecting male buckle 801 and the connecting female buckle 802 are fastened or separated under the action of external force.

[0039] Both the interior of the lens holder 6 and the connecting buckle 801 are provided with clamping grooves 9 that match the shape of the optical lens edge. The two sides of the clamping grooves 9 are located on the two sides of the optical lens and are in contact with the surface of the optical lens. The connecting buckle 801 and the clamping grooves 9 on the lens holder 6 together form a ring structure with the same shape as the edge of the optical lens.

[0040] The specific method for fixing and detaching the optical lens from the lens holder 6 is as follows: First, the optical lens is inserted into the clamping groove 9 on the connecting buckle 801. Driven by the connecting buckle 801, it is inserted from the lens placement opening 7 into the clamping groove 9 inside the lens holder 6. The clamping groove 9 on the connecting buckle 801 and the clamping groove 9 on the lens holder 6 engage to form a ring structure that clamps and accommodates the optical lens inside. Then, the optical lens is fixed to the lens holder 6 by pressing the connecting buckle 801 firmly onto the connecting nut 802. To prevent the optical lens from shifting due to the shaking of the first cylinder 101 and the second cylinder 201 during the shooting process, thus avoiding the distortion of the shooting light angle, the connecting male buckle 801 is forcefully separated from the connecting female buckle 802 when the optical lens is removed. Driven by the connecting male buckle 801, the optical lens is taken out of the clamping groove 9 on the lens holder 6 from the lens holder 6 through the lens placement port 7. Then, the optical lens is taken out from the clamping groove 9 on the connecting male buckle 801.

[0041] like Figure 1 , 4 As shown in Figure 5, the connecting mechanism 3 includes multiple connecting rods 301 arranged in a ring along the end face of the first cylinder 101 relative to the side of the second cylinder 201, and a limiting strip 302 installed at the other end of each connecting rod 301. The limiting strip 302 has a vertically symmetrical structure about the connecting rods 301. A connecting groove 303 is provided in a ring along the end face of the second cylinder 201 relative to the side of the first cylinder 101 for the multiple connecting rods 301 to wedge into. The length of the limiting strip 302 is the same as the inner diameter of the cross section of the connecting groove 303. The limiting strip 302 slides axially along the connecting groove 303 under the action of external force. An adjustment and positioning mechanism 4 is provided between the limiting strip 302 and the groove wall of the connecting groove 303. The adjustment and positioning mechanism 4 fixes the sliding position of the limiting strip 302 in the connecting groove 303.

[0042] The connection method between the first cylinder 101 and the second cylinder 201 is as follows: First, align the limiting strip 302 at the front end of the connecting rod 301 with the connecting groove 303 one by one. Then, hold the first cylinder 101 and apply a pushing force to the side of the second cylinder 201 to allow the limiting strip 302 to enter the connecting groove 303, with both ends of the limiting strip 302 sliding against the groove wall of the connecting groove 303. Based on the optical parameters such as the surface shape and focal length of the optical lens at the end of the first cylinder 101, use the adjusting positioning mechanism 4 to control the fixed position of the limiting strip 302 on the groove wall of the connecting groove 303. This allows adjustment of the position of the connecting rod 301 exposed at the end of the first cylinder 101 and the second cylinder 201. The length between the front ends of the two cylinders 201 is adjusted to maintain a distance between the optical lenses at the end of the first cylinder 101 and the front end of the second cylinder 201, allowing for better matching of the optical lenses and enabling the optical lenses to work properly. When separating the first cylinder 101 and the second cylinder 201, the adjusting positioning mechanism 4 is used to release the limiting strip 302 from the groove wall of the connecting groove 303 into a free sliding state. The first cylinder 101 is held and pulled away from the second cylinder 201, causing the limiting strip 302 to disengage from the connecting groove 303, thus separating the first cylinder 101 and the second cylinder 201.

[0043] The adjusting positioning mechanism 4 includes two recessed mounting holes 401 at both ends of the limiting strip 302. A positioning bead 402 is provided at the opening of each mounting hole 401. The positioning bead 402 is connected to the mounting hole 401 via a linear spring strip 403 located inside the mounting hole 401. The diameter of the positioning bead 402 is the same as the cross-sectional diameter of the mounting hole 401. When the linear spring strip 403 is at its original length, half of the positioning bead 402's volume is exposed at the front end of the opening of the mounting hole 401. The groove 303 has two axial grooves 404 on its wall, which allow the exposed parts of the positioning top beads 402 in the two mounting holes 401 to slide axially. Multiple positioning bead holes 405 that match the positioning top beads 402 are arranged linearly on the upper part of the axial grooves 404. The positioning top beads 402 slide into or out of the positioning bead holes 405 under the action of external force. The width of the axial grooves 404 is smaller than the diameter of the open part of the positioning bead holes 405, and the size of the positioning bead holes 405 is adapted to the size of the exposed parts of the positioning top beads 402.

[0044] The method for adjusting the distance between the end of the first cylinder 101 and the front end of the second cylinder 201 using the positioning mechanism 4 is as follows: During the sliding contact of the limiting strip 302 on the wall of the connecting groove 303, the positioning ball 402 at the opening of the mounting hole 401 at the end face of the limiting strip 302 slides along the axial groove 404. When the positioning ball 402 slides in the axial groove 404, it is compressed by the reaction force of the groove wall of the axial groove 404, causing the ball of the positioning ball 402 to retract into the mounting hole 401, until the ball of the positioning ball 402 slides into the positioning ball hole 405 of the corresponding size and is then pressed by the linear spring strip 403. The new ejection fixes the limiting strip 302 in the position of the positioning bead hole 405. The length of the connecting rod 301 exposed between the end of the first cylinder 101 and the front end of the second cylinder 201 meets the optical parameter requirements of the optical lens between the end of the first cylinder 101 and the front end of the second cylinder 201. During the process of pulling the limiting strip 302 outward from the connecting groove 303 by external force, the positioning bead 402 slides from the positioning bead hole 405 into the axial sliding groove 404, releasing the position locking state between the positioning bead 402 and the positioning bead hole 405, so that the limiting strip 302 is in a free sliding state until the limiting strip 302 is completely detached from the connecting groove 303.

[0045] Multiple strip spring plates 5 are arranged circumferentially on the surface of the connecting rod 301. One end of each strip spring plate 5 is connected to the end of the connecting rod 301 located at the end face of the first cylinder 101. The other ends of the multiple strip spring plates 5 are independent and freely suspended. The other ends of the multiple freely suspended strip spring plates 5 form a planar shape that is consistent with the cross-sectional plane shape of the connecting groove 303. The strip spring plates 5 are pushed into the connecting groove 303 or pulled out from the connecting groove 303 under the action of external force.

[0046] When the limiting strip 302 enters the connecting groove 303, the connecting rod 301 is gradually pushed deeper into the connecting groove 303. The free suspended end of the strip spring plate 5 enters the connecting groove 303. Due to the pressure from the groove wall of the connecting groove 303, the strip spring plate 5 deforms under force and forms a planar shape inside the connecting groove 303 that is the same as the plane of the hole diameter of the connecting groove 303. Furthermore, due to the elastic deformation, the strip spring plate 5 comes into contact with the groove wall of the connecting groove 303, thereby clamping and fixing the connecting rod 301 to the groove wall of the connecting groove 303. This further prevents the connecting rod 301 from shaking in the connecting groove 303, maintains the stability of the connecting rod 301 in the connecting groove 303, and thus ensures the stability of the connection between the first cylinder 101 and the second cylinder 201.

[0047] like Figure 6 As shown, based on the structure of the optical lens module described above, this invention provides a method for separate assembly, comprising the following steps:

[0048] For S100, depending on the needs of taking photos or achieving photographic effects, select the single or multiple optical lenses to be used;

[0049] S200: Place the optical lens from the lens mounting opening on the first cylinder and the second cylinder onto the lens holder, and fix its position using the mating buckle to form the first split lens assembly and the second split lens assembly.

[0050] S300: The first split lens assembly and the second split lens assembly are connected using a connecting mechanism, and the distance between the first end of the first barrel and the second end of the barrel is adjusted by an adjusting positioning mechanism to meet the optical parameters of the optical lens according to the optical parameter requirements of the optical lens between the end of the first barrel and the front end of the second barrel.

[0051] S400 After shooting, the first and second split lens assemblies are separated, and the optical lenses are gradually removed from the first and second barrels of the first and second split lens assemblies.

[0052] This invention combines optical lens modules using a split structure. Firstly, it employs a first and second split lens assembly as segmented units. Within each of these assemblies, multiple lens mounts are installed in the first and second cylinders to assemble optical lens combinations that produce various effects, adapting to different shooting scenarios. The segmented structure is further divided into individual segments for complete optical lens assembly. A connecting mechanism connects the first and second cylinders. Positioning beads at the opening of the limiting strip at the front end of the connecting rod on the first cylinder slide between multiple positioning bead holes inside the connecting groove on the second cylinder, adjusting the connection distance between the first and second cylinders. This ensures that the focal length of the optical lens at the end of the first cylinder converges onto the optical lens at the front end of the second cylinder, preventing focusing problems. The number of lens modules and the combination of optical lenses within each module can be selected according to application requirements, improving the compatibility and shooting effect of the lens product.
