Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a lens mount, lens module, and electronic device. Background Technology

[0002] Lens mounts and lenses are usually connected by adhesive. With the increasing demand for module specifications and miniaturization, non-circular lens designs have emerged, which limits the space available for adhesive application. This results in poor bonding strength between the lens mount and the lens, making the lens prone to detachment during service. Utility Model Content

[0003] The purpose of embodiments of this application is to provide a lens mount, a lens module, and an electronic device for improving the reliability of the connection between the lens mount and the lens.

[0004] To achieve the above objectives, embodiments of this application provide the following technical solutions:

[0005] On one hand, a lens mount is provided. The lens mount includes: a mounting sleeve, the mounting sleeve including an inner wall and two first surfaces arranged axially on the mounting sleeve, the two first surfaces being connected to the inner wall and intersecting the axial direction of the mounting sleeve, the inner wall being provided with a first groove and a second groove, the extension direction of the first groove intersecting the axial direction of the mounting sleeve, the second groove extending along the axial direction of the mounting sleeve, and the second groove extending to at least one of the first surfaces.

[0006] In the lens mount provided in this application embodiment, both the first groove and the second groove can be used to accommodate adhesive. By providing the first groove and the second groove on the inner wall of the mounting sleeve of the lens mount, the amount of adhesive that the mounting sleeve can accommodate can be increased, thereby increasing the bonding area between the mounting sleeve and the lens, improving the locking strength between the lens mount and the lens, and improving the reliability of the connection between the lens mount and the lens. Furthermore, during the manufacturing of the lens mount, the mold for preparing the first groove can move radially along the mounting sleeve to achieve demolding, while the mold for preparing the second groove can move axially along the mounting sleeve to achieve demolding.

[0007] In some embodiments, the first groove and the second groove are spaced apart along a circumferential direction, wherein the circumferential direction surrounds the axial direction of the mounting sleeve.

[0008] This design increases the length of the grooved portion on the inner wall in the circumferential direction, thereby improving the uniformity of adhesive distribution between the inner wall and the lens, and ultimately enhancing the bonding strength between the mounting sleeve and the lens.

[0009] In some embodiments, there are multiple first grooves, which are spaced apart along a circumferential direction, wherein the circumferential direction surrounds the axial direction of the mounting sleeve; wherein at least one second groove is provided between at least partially adjacent two first grooves.

[0010] The mounting sleeve has a gap between adjacent first grooves, and a second groove can be provided between adjacent first grooves in the circumferential direction. The number of second grooves between adjacent first grooves can be one or more. Alternatively, no second groove may be provided between adjacent first grooves in the circumferential direction. By providing multiple first grooves spaced apart in the circumferential direction, the amount of adhesive that the mounting sleeve can hold can be increased, thereby improving the bonding strength between the mounting sleeve and the lens. Furthermore, by providing second grooves between adjacent first grooves, the number of grooves on the inner wall of the mounting sleeve can be increased, thereby increasing the amount of adhesive that the mounting sleeve can hold, improving the bonding strength between the mounting sleeve and the lens, and improving the connection reliability between the lens mount and the lens. Moreover, the third mold used to prepare the second groove does not hinder the demolding of the second mold used to prepare the first groove.

[0011] In some embodiments, the inner wall includes a plurality of connecting walls, and a first groove and a second groove are respectively provided on two adjacent connecting walls.

[0012] By setting a first groove and a second groove on two adjacent connecting walls respectively, the first groove and the second groove can be alternately set, which can not only ensure the number of grooves set on the inner wall, but also ensure the amount of glue contained in the mounting sleeve.

[0013] In some embodiments, the plurality of connecting walls includes a first connecting wall and a second connecting wall, the first connecting wall and the second connecting wall are alternately arranged along a circumferential direction, at least one of the first connecting wall and the second connecting wall is a plane, wherein the circumferential direction is around the axial direction of the mounting sleeve; wherein one of the first connecting wall and the second connecting wall is provided with a first groove, and the other of the first connecting wall and the second connecting wall is provided with a second groove.

[0014] The first connecting wall can be planar or non-planar. The second connecting wall can also be planar or non-planar. For example, a non-planar surface can be curved. Therefore, the first groove can be located on a planar surface or a non-planar surface, and the second groove can also be located on a planar surface or a non-planar surface. The connection between the non-planar surface and the lens is relatively weak; by using the first or second groove on the non-planar surface, the bonding strength between the non-planar surface and the lens can be improved.

[0015] In some embodiments, the second groove includes a first opening and a first bottom disposed opposite to each other, the width of the first bottom in a first direction being unequal to the width of the first opening in the first direction, wherein the first opening is disposed on the inner wall and the first direction is perpendicular to the axial direction of the mounting sleeve.

[0016] With this configuration, the sidewalls of the second groove can be tilted, allowing more adhesive to be contained within the groove. This improves the bonding strength between the mounting sleeve and the lens, and enhances the reliability of the connection between the lens mount and the lens.

[0017] In some embodiments, the second groove is a trapezoidal groove or a V-shaped groove.

[0018] Specifically, by designing the second groove as a trapezoidal groove, the volume of the second groove can be increased, thereby increasing the amount of adhesive it can hold. This, in turn, improves the bonding strength between the mounting sleeve and the lens, and enhances the connection reliability between the lens mount and the lens. Alternatively, by designing the second groove as a V-shaped groove, the second groove can be continuously arranged along the circumferential direction, increasing the arrangement density of the second groove. This further increases the amount of adhesive the mounting sleeve can hold, and enhances the bonding strength between the mounting sleeve and the lens.

[0019] In some embodiments, at least a portion of the second groove extends through the mounting sleeve along its axial direction.

[0020] By making the second groove penetrate the mounting sleeve, the volume of the second groove can be increased, thereby increasing the volume of adhesive that the second groove can hold, and thus improving the bonding strength between the mounting sleeve and the lens.

[0021] In some embodiments, the number of second grooves is multiple, some of the second grooves and the first grooves are spaced apart along the circumferential direction, and another portion of the second grooves are disposed on at least one side of at least one first groove in the axial direction of the mounting sleeve, wherein the circumferential direction surrounds the axial direction of the mounting sleeve.

[0022] By having some of the second grooves and the first grooves spaced apart in the circumferential direction, and another portion of the second grooves and the first grooves spaced apart in the axial direction, the number of second grooves provided on the inner wall of the mounting sleeve can be increased, thereby increasing the amount of adhesive that the mounting sleeve can hold, and thus increasing the bonding strength between the mounting sleeve and the lens, and improving the connection reliability between the two.

[0023] In some embodiments, the lens mount further includes a metal connector, which is embedded in the mounting sleeve and a portion of its surface is exposed on the inner wall.

[0024] In this design, a portion of the surface of the metal connector is exposed on the inner wall, and the adhesive can be located between the metal connector and the lens. The bonding strength between the metal connector and the adhesive is relatively high, thus improving the connection strength between the mounting sleeve and the lens.

[0025] In some embodiments, the inner wall includes a first connecting wall and a second connecting wall, which are alternately arranged along a circumferential direction. The first connecting wall is a plane, and the second connecting wall is an arcuate surface. The circumferential direction is around the axial direction of the mounting sleeve. A portion of the surface of the metal connector is exposed to the second connecting wall, and the portion of the surface of the metal connector exposed to the second connecting wall is an arcuate surface.

[0026] Since the second connecting wall is an arc-shaped surface, the connection between the second connecting wall and the lens is relatively weak. By exposing part of the surface of the metal connector to the second connecting wall, the second connecting wall can be bonded to the lens through the metal connector, thereby improving the connection stability between the mounting sleeve and the lens.

[0027] In some embodiments, the metal connector has a second groove on at least one side of the mounting sleeve along its axial direction.

[0028] At least a portion of the second groove and the metal connector are disposed on the same connecting wall. By disposing of the second groove and the metal connector on the same connecting wall, the bonding strength between the connecting wall and the lens can be improved. The connecting wall can be either a first connecting wall or a second connecting wall.

[0029] In some embodiments, the metal connector has a first groove on at least one side of the mounting sleeve along its axial direction.

[0030] At least a portion of the first groove and the metal connector are disposed on the same connecting wall. By disposing of the first groove and the metal connector on the same connecting wall, the bonding strength between the connecting wall and the lens can be improved. The connecting wall can be either a first connecting wall or a second connecting wall.

[0031] In some embodiments, the metal connector includes a connecting portion and a fitting portion, wherein the connecting portion is fitted within a mounting sleeve, the connecting portion includes a third surface and a fourth surface disposed opposite to each other, wherein the third surface is exposed on the inner wall, and the fitting portion is connected to the fourth surface and fitted within the mounting sleeve.

[0032] In particular, by providing multiple fitting parts on one side of the connection, the fitting strength between the metal connector and the mounting sleeve can be further improved.

[0033] On the other hand, a lens module is provided. The lens module includes: a lens mount and a lens as provided in some of the above embodiments, with the lens disposed within a mounting sleeve of the lens mount.

[0034] The lens module provided in this application includes all the structures of the lens mounts provided in the above embodiments. Therefore, the lens module provided in this application includes all the beneficial effects of the lens mounts provided in the above embodiments, which will not be repeated here.

[0035] In some embodiments, the inner wall of the mounting sleeve includes a first connecting wall and a second connecting wall, which are alternately arranged along a circumferential direction. The first connecting wall is a plane, and the second connecting wall is an arcuate surface. The circumferential direction surrounds the axial direction of the mounting sleeve. The lens module further includes a first colloid and a second colloid. The first colloid is disposed in a groove on the first connecting wall and connected to the lens. The second colloid is disposed in a groove on the second connecting wall and connected to the lens. The groove on the first connecting wall includes a first groove and / or a second groove, and the groove on the second connecting wall includes a first groove and / or a second groove. The modulus of the first colloid is greater than the modulus of the second colloid.

[0036] The higher the modulus of the colloid, the greater its stiffness; conversely, the lower the modulus, the better its elasticity. By filling the groove on the first connecting wall with a first colloid of higher modulus, the overall stiffness of the lens module structure is improved due to the higher stiffness of the first colloid. Conversely, by filling the groove on the second connecting wall with a second colloid of lower modulus, the second colloid, due to its higher elasticity, acts as a buffer when the second connecting wall is subjected to external forces, thereby improving the bonding strength between the lens and the mounting sleeve.

[0037] In some embodiments, a locking block is provided on the outer surface of the inner wall of the mounting sleeve facing the lens, and the locking block is located in the second groove.

[0038] The clip protrudes from the lens surface facing the inner wall, and the adhesive in the second groove can also cover the surface of the clip. By setting the clip on the lens, the contact area between the adhesive and the lens can be increased, thereby improving the bonding strength between the lens and the mounting sleeve.

[0039] In some embodiments, the lens is provided with an annular groove on the outer surface of the inner wall of the mounting sleeve.

[0040] The annular groove can be used to hold adhesive, thereby increasing the amount of adhesive between the lens and the inner wall of the mounting sleeve, which in turn can improve the bonding strength between the lens and the mounting sleeve and improve the connection reliability between the lens and the lens mount.

[0041] In another aspect, an electronic device is provided. This electronic device includes the lens module provided in some of the above embodiments.

[0042] The electronic device provided in this application embodiment includes all the structures of the lens module provided in some of the above embodiments. Therefore, the electronic device provided in this application embodiment includes all the beneficial effects of the lens module provided in some of the above embodiments, which will not be repeated here.

[0054] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0055] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" and its other forms, such as the third-person singular "comprising" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "some embodiments," "examples," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0056] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0057] In describing some embodiments, the term "connection" and its derivative expressions may be used. The term "connection" should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0058] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0059] As used herein, “parallel” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°.

[0060] Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0061] Please see Figure 1This application provides an electronic device 4000. For example, the electronic device 4000 has a camera function. For instance, the electronic device can be a mobile phone, tablet, personal digital assistant (PDA), television, smart wearable products (e.g., smartwatches, smart bracelets), virtual reality (VR) terminal devices, and drones, etc. Figure 1 In this example, we will use the 4000 electronic device as an example of a mobile phone.

[0062] The electronic device 4000 includes a lens module 3000. The lens module 3000 includes a lens mount and a lens.

[0063] Figure 2 This is a schematic diagram of the structure of the lens mount 1000 and the mold used to manufacture the lens mount 1000 in the prior art.

[0064] Please see Figure 2 In the prior art, the lens mount 1000 may include a fixing sleeve 1001, and the lens may be disposed within the fixing sleeve 1001. The lens and the fixing sleeve 1001 may be bonded together with an adhesive.

[0065] The inner surface of the fixing sleeve 1001 is not circular. Multiple receiving grooves are provided on the inner surface of the fixing sleeve 1001, spaced apart sequentially along a surrounding direction. These receiving grooves can be used to hold adhesive, thereby increasing the amount of adhesive between the lens and the inner surface of the fixing sleeve 1001. The surrounding direction is axially surrounding the fixing sleeve 1001.

[0066] In the process of manufacturing the fixed sleeve 1001, a manufacturing mold is required. Since the inner surface of the fixed sleeve 1001 is not circular, the manufacturing module includes multiple first molds 1002 located inside the fixed sleeve 1001. The first molds 1002 are used to create receiving grooves on the inner surface of the fixed sleeve 1001. During demolding, the multiple first molds 1002 move towards the axis of the fixed sleeve 1001, thereby allowing the fixed sleeve 1001 to be demolded. Figure 2 As shown, the direction pointed to by arrow S1 is the direction of movement of the first mold 1002 toward the axis of the fixed sleeve 1001. It can be understood that the direction of movement of the first mold 1002 is different at different positions.

[0067] As multiple receiving grooves are spaced apart on a portion of the inner surface of the fixing sleeve 1001, while the remaining portion of the inner surface of the fixing sleeve 1001 is not provided with receiving grooves, the connection between the inner surface without receiving grooves and the lens is weak, resulting in poor adhesion between the lens mount 1000 and the lens. Consequently, the lens module 3000 is prone to lens detachment during service.

[0068] Based on this, this application provides a lens module.

[0069] Figure 3 This is a top view of the lens module 3000 provided in an embodiment of this application. Figure 4 for Figure 3 A schematic diagram of the structure of the lens mount 1000, wherein, in Figure 4 The image shows part of the lens mount 1000.

[0070] Please see Figure 3 and Figure 4 The lens module 3000 may include a lens mount 1000 and a lens 2000.

[0071] The lens mount 1000 includes a mounting sleeve 100, which includes an inner wall 110 and two first surfaces 120 arranged in the axial direction L of the mounting sleeve 100. The first surfaces 120 are connected to the inner wall 110 and intersect with the axial direction of the mounting sleeve 100.

[0072] The mounting sleeve 100 may have an annular cross-section, wherein the cross-section of the mounting sleeve 100 is perpendicular to the axial direction L of the mounting sleeve 100. For example... Figure 3 As shown, the axial direction L of the mounting sleeve 100 is perpendicular to the paper surface. Figure 3 Taking the axial direction L of the mounting sleeve 100 as the direction perpendicular to the paper and outward as an example, the axial direction L is illustrated.

[0073] The mounting sleeve 100 may include an inner wall 110, an outer wall 130, and two first surfaces 120 disposed opposite each other in the axial direction L, wherein the inner wall 110 and the outer wall 130 may be located between the two first surfaces 120. The inner wall 110 is located within the area enclosed by the outer wall 130, and the inner wall 110 may enclose a mounting area, within which the lens 2000 may be located. The inner wall 110 may be cylindrical or non-cylindrical, and its shape may be adapted to the shape of the lens 2000.

[0074] Both first surfaces 120 can intersect the axial direction L; for example, the first surface 120 can be perpendicular to the axial direction L.

[0075] The inner wall 110 is provided with a first groove 140 and a second groove 150. The extension of the first groove 140 intersects the axial direction along the mounting sleeve 100. The second groove 150 extends along the axial direction L of the mounting sleeve 100 and extends to at least one first surface 120.

[0076] For example, the extending direction of the first groove 140 may be perpendicular to the axial direction L of the mounting sleeve 100. Alternatively, the extending direction of the first groove 140 may not necessarily be perpendicular to the axial direction L of the mounting sleeve 100.

[0077] The number of first grooves 140 can be one or more, and the number of second grooves 150 can be one or more.

[0078] One end of the second groove 150 may extend to a first surface 120, wherein the second groove 150 may include a first slot 151 and a second slot 152, wherein the first slot 151 is located on the inner wall 110 and the second slot 152 is located on the first surface 120.

[0079] The second groove 150 can also extend to the two first surfaces 120 at both ends of the mounting sleeve 100 along the axial direction L. In this case, the second groove 150 can include three slots, which are respectively disposed on the inner wall 110 and the two first surfaces 120.

[0080] When manufacturing the lens mount 1000, a mold is required. The mold may include a second mold and a third mold. The second mold and the third mold are located inside the mounting sleeve 100. The second mold is used to form the portion on the inner wall 110 where the first groove 140 is provided, and the third mold is used to form the portion on the inner wall 110 where the second groove 150 is provided. During the demolding process, the second mold moves along the radial direction D of the mounting sleeve 100 and in the direction pointing to the axis, thereby achieving demolding, while the third mold moves along the axial direction L of the inner wall 110, thereby achieving demolding. At this time, the third mold can be demolded through the second slot.

[0081] Both the first groove 140 and the second groove 150 can be used to hold adhesive. By providing the first groove 140 and the second groove 150 on the inner wall 110 of the mounting sleeve 100 of the lens mount 1000, the amount of adhesive that the mounting sleeve 100 can hold can be increased, thereby improving the bonding strength between the lens mount 1000 and the lens 2000 and improving the reliability of the connection between the lens mount 1000 and the lens 2000. Furthermore, during the manufacturing of the lens mount 1000, the mold used to manufacture the first groove 140 can move along the radial direction D of the mounting sleeve 100 to achieve demolding, while the mold used to manufacture the second groove 150 can move along the axial direction of the mounting sleeve 100 to achieve demolding, and the mold used to manufacture the second groove 150 will not hinder the demolding of the mold used to manufacture the first groove 140.

[0082] Please see Figure 4 In some embodiments, the first groove 140 and the second groove 150 are spaced apart along a circumferential direction, wherein the circumferential direction S2 surrounds the axial direction L of the mounting sleeve 100.

[0083] This configuration increases the length of the grooved portion on the inner wall 110 in the circumferential direction S2, thereby improving the uniformity of adhesive distribution between the inner wall 110 and the lens 2000, and further enhancing the bonding strength between the mounting sleeve 100 and the lens 2000.

[0084] In other embodiments, at least a portion of the first groove 140 is provided with a second groove 150 on one side in the axial direction L.

[0085] Please see Figure 4 In some embodiments, there are multiple first grooves 140, which are spaced apart along the circumferential direction S2, wherein at least one second groove 150 is provided between at least two partially adjacent first grooves 140.

[0086] There is a gap between two adjacent first grooves 140. A second groove 150 can be provided between two adjacent first grooves 140 in the circumferential direction S2. The number of second grooves 150 provided between two adjacent first grooves 140 can be one or more. Of course, there may be no second groove 150 provided between two adjacent first grooves 140 in the circumferential direction S2.

[0087] For example, along the circumferential direction S2, the inner wall 110 is sequentially provided with a first groove 140, a second groove group, and another second groove group. The second groove group includes at least one second groove 150. It should be noted that this example is only one possible arrangement of the first groove 140 and the second groove 150.

[0088] By providing multiple first grooves 140 spaced apart along the circumferential direction S2, the amount of adhesive that the mounting sleeve 100 can hold can be increased, thereby improving the bonding strength between the mounting sleeve 100 and the lens 1000 and improving the connection reliability between the lens mount 1000 and the lens 2000.

[0089] In some examples, a second groove 150 is provided between any two adjacent first grooves 140 in the circumferential direction S2. In this case, the first grooves 140 and the second groove group are alternately arranged in the circumferential direction S2. For example, the inner wall 110 is provided with the following sequence: first groove 140, second groove group, first groove 140, second groove group, first groove 140, second groove group, first groove 140, second groove group.

[0090] Specifically, by setting a second groove 150 between any two adjacent first grooves 140, and increasing the number of grooves set on the inner wall 110, the amount of adhesive that the mounting sleeve 100 can hold can be increased, thereby improving the bonding strength between the mounting sleeve 100 and the lens 1000, improving the connection reliability between the lens mount 1000 and the lens 2000, and the third mold used to prepare the second groove 150 will not hinder the demolding of the second mold used to prepare the first groove 140.

[0091] Please see Figure 3 and Figure 4 In some embodiments, the inner wall 110 includes a plurality of connecting walls, and a first groove 140 and a second groove 150 are respectively provided on two adjacent connecting walls.

[0092] The connecting walls can be planar or curved. For example, if all the connecting walls are planar, the inner wall 110 can be prismatic.

[0093] For example, some connecting walls are planar, while others are curved. In this case, among two adjacent connecting walls, one is planar and the other is curved. Alternatively, both adjacent connecting walls may be planar; or both adjacent connecting walls may be curved.

[0094] By setting a first groove 140 and a second groove 150 on two adjacent connecting walls respectively, the first groove 140 and the second groove 150 can be alternately set, which can not only ensure the number of grooves set on the inner wall 110, but also ensure the amount of glue contained in the mounting sleeve 100.

[0095] In some embodiments, the plurality of connecting walls include a first connecting wall 111 and a second connecting wall 112, the first connecting wall 111 and the second connecting wall 112 being alternately arranged along the circumferential direction S2, wherein at least one of the first connecting wall 111 and the second connecting wall 112 is a plane.

[0096] The first connecting wall 111 can be planar or non-planar. The second connecting wall 112 can also be planar or non-planar. For example, a non-planar surface can be curved. Figure 3 and Figure 4 In the middle, the first connecting wall 111 is a plane, and the second connecting wall 112 is an arc surface.

[0097] In this configuration, the first connecting wall 111 and the second connecting wall 112 are alternately arranged. Along the circumferential direction S2, the following sequence of connecting walls are arranged: first connecting wall 111, second connecting wall 112, first connecting wall 111, second connecting wall 112, first connecting wall 111, second connecting wall 112, first connecting wall 111, second connecting wall 112. The number of first connecting walls 111 can be 2, 3, 4, or even more, and the number of second connecting walls 112 can be 2, 3, 4, or even more.

[0098] The lengths of the multiple first connecting walls 111 in the circumferential direction S2 can be equal, or the lengths of the multiple first connecting walls 111 in the circumferential direction S2 can be unequal.

[0099] The lengths of the multiple second connecting walls 112 in the circumferential direction S2 can be equal, or the lengths of the multiple second connecting walls 112 in the circumferential direction S2 can be unequal.

[0100] A first groove 140 is provided on one of the first connecting wall 111 and the second connecting wall 112, and a second groove 150 is provided on the other of the first connecting wall 111 and the second connecting wall 112.

[0101] Therefore, the first groove 140 can be disposed on a plane or on a non-plane, and the second groove 150 can be disposed on a plane or on a non-plane. The connection between the non-plane and the lens is relatively weak; by using the first groove 140 or the second groove 150 on the non-plane, the bonding strength between the non-plane and the lens can be improved.

[0102] For example, a first groove 140 is provided on the first connecting wall 111, and a second groove 150 is provided on the second connecting wall 112. In this case, one or more second grooves 150 can be provided on a second connecting wall 112, and one or more first grooves 140 can be provided on a first connecting wall 111.

[0103] For example, a second groove 150 is provided on the first connecting wall 111, and a first groove 140 is provided on the second connecting wall 112. In this case, one or more second grooves 150 can be provided on a first connecting wall 111, and one or more first grooves 140 can be provided on a second connecting wall 112.

[0104] For example, the second connecting wall 112 is an arc-shaped surface. By providing a first groove 140 or a second groove 150 on the second connecting wall 112, the bonding strength between the second connecting wall 112 and the lens 2000 can be improved.

[0105] In other embodiments, a first groove 140 may extend from a first connecting wall 111 to a second connecting wall 112. A portion of the second grooves 150 in a second groove group may be disposed on the second connecting wall 112, while another portion of the second grooves 150 may be disposed on the first connecting wall 111; or all the second grooves 150 in a second groove group may be disposed on a single second connecting wall 112.

[0106] In some embodiments, at least a portion of the second groove 150 extends through the mounting sleeve 100 along the axial direction L of the mounting sleeve 100.

[0107] At this time, the second groove 150 may include three slots, one of which is located on the inner wall 110, another slot is located on the first surface 120, and yet another slot is located on another first surface 120.

[0108] By allowing the second groove 150 to penetrate the mounting sleeve 100, the volume of the second groove 150 can be increased, thereby increasing the volume of adhesive that the second groove 150 can hold, and thus improving the bonding strength between the mounting sleeve 100 and the lens 2000.

[0109] In some examples, when there are multiple second grooves 150, some of the second grooves 150 penetrate the mounting sleeve 100 along the axial direction L of the mounting sleeve 100, while other parts of the second grooves 150 do not penetrate the mounting sleeve 100.

[0110] In other examples, where there are one or more second grooves 150, all the second grooves 150 extend through the mounting sleeve 100 along the axial direction L of the mounting sleeve 100.

[0111] Figure 5 for Figure 3 Cross-sectional view at point A-A' Figure 6 for Figure 3 Another cross-sectional schematic diagram of the lens module 3000, in which... Figure 6 The image only shows a portion of the 3000 lens module.

[0112] Please see Figure 5 and Figure 6 In some embodiments, there are multiple second grooves 150, some of the second grooves 150 and the first grooves 140 are spaced apart along the circumferential direction S2, and another portion of the second grooves 150 are provided on at least one side of at least one first groove 140 in the axial direction L of the mounting sleeve 100.

[0113] The second groove 150, which is spaced apart from the first groove 140 in the circumferential direction S2, may penetrate the mounting sleeve 100 along the axial direction L of the mounting sleeve 100, or it may not penetrate the mounting sleeve 100.

[0114] The second groove 150, which is spaced apart from the first groove 140 along the axial direction L of the mounting sleeve 100, may not penetrate the mounting sleeve 100.

[0115] In a plurality of first grooves 140, at least a portion of the first grooves 140 are provided with a second groove 150 on at least one side in the axial direction L of the mounting sleeve 100. For example, each first groove 140 is provided with a second groove 150 on at least one side in the axial direction L of the mounting sleeve 100. For example, a portion of the first grooves 140 are provided with a second groove 150 on at least one side in the axial direction L of the mounting sleeve 100.

[0116] For a first groove 140, at least one second groove 150 may be provided on one side of the first groove 140 in the axial direction L, or at least one second groove 150 may be provided on each side of the first groove 140 in the axial direction L. The number of second grooves 150 provided on both sides of the first groove 140 in the axial direction L may be the same or different. Of course, a first groove 140 may not have any second grooves 150 provided on either side of the mounting sleeve 100 in the axial direction L.

[0117] In this embodiment of the application, by having some of the second grooves 150 and the first grooves 140 spaced apart in the circumferential direction S2, and another portion of the second grooves 150 and the first grooves 140 spaced apart in the axial direction L, the number of second grooves 150 provided on the inner wall 110 of the mounting sleeve 100 can be increased, thereby increasing the amount of adhesive that the mounting sleeve 100 can hold, and thus increasing the bonding strength between the mounting sleeve 100 and the lens 2000, and improving the connection reliability between the two.

[0118] Figure 7 for Figure 3 Cross-sectional view at point B-B'.

[0119] Please see Figure 7The first groove 140 may include a second groove bottom 141, wherein the width of the second groove bottom 141 in the axial direction L is smaller than the width of the groove opening of the first groove 140 in the axial direction L. This arrangement facilitates demolding of the second mold used to prepare the first groove 140.

[0120] Of course, the width of the second groove bottom 141 in the axial direction L can also be equal to the width of the groove opening of the first groove 140 in the axial direction L.

[0121] Figure 8 This is a schematic diagram of the structure of the second groove 150 provided in an embodiment of this application. Figure 9 This is another structural schematic diagram of the second groove 150 provided in an embodiment of this application. Figure 10 This is another structural schematic diagram of the second groove 150 provided in the embodiments of this application.

[0122] Please see Figures 8 to 10 and combined Figure 4 In some embodiments, the second groove 150 includes a first groove opening 151 and a first groove bottom 155 disposed opposite to each other. The width of the first groove bottom 155 in the first direction F1 is not equal to the width of the first groove opening 151 in the first direction F1. The first groove opening 151 is disposed on the inner wall 110, and the first direction F1 is perpendicular to the axial direction L of the mounting sleeve 100.

[0123] The width of the first slot 151 in the first direction F1 is H1; the width of the first slot bottom 155 in the first direction F1 is H2, wherein H1≠H2.

[0124] With this configuration, the sidewall of the second groove 150 can be inclined, so that more glue can be contained in the second groove 150, thereby improving the bonding strength between the mounting sleeve 100 and the lens 1000 and improving the connection reliability between the lens mount 1000 and the lens 2000. The sidewall of the second groove 150 is connected to the bottom 155 of the second groove 150.

[0125] In some embodiments, the second groove 150 is a trapezoidal groove or a V-shaped groove.

[0126] Please see Figure 8 and Figure 9 The second groove 150 is a trapezoidal groove. For example... Figure 8 As shown, the width H1 of the first groove 151 in the first direction F1 is less than the width H2 of the first groove bottom 155 in the first direction F1, i.e., H1 < H2. At this time, the second groove 150 is a dovetail groove.

[0127] like Figure 9 As shown, the width H1 of the first slot 151 in the first direction F1 is greater than the width H2 of the first slot bottom 155 in the first direction F1, that is, H1 > H2.

[0128] By setting the second groove 150 as a trapezoidal groove, the volume of the second groove 150 can be increased, thereby increasing the amount of adhesive that the second groove 150 can hold. This increases the adhesive strength between the mounting sleeve 100 and the lens 1000, and improves the connection reliability between the lens mount 1000 and the lens 2000.

[0129] Please see Figure 10 The second groove 150 can also be a "V" shaped groove. In this case, the width of the bottom of the first groove 155 in the first direction F1 is 0.

[0130] With this configuration, the second groove 150 can be continuously arranged along the circumferential direction S2, thereby increasing the arrangement density of the second groove 150, which in turn increases the amount of adhesive that the mounting sleeve 100 can hold, and improves the bonding strength between the mounting sleeve 100 and the lens 2000.

[0131] Of course, in some other embodiments, the width H1 of the first slot 151 in the first direction F1 can be equal to the width H2 of the first slot bottom 155 in the first direction F1.

[0132] Figure 11 This is a schematic diagram of the lens module 3000 provided in an embodiment of this application. Wherein, in Figure 11 Only the lens mount 1000 and the lens 2000 are shown in the diagram.

[0133] Please see Figure 11 In some embodiments, the lens mount 10000 further includes a metal connector 200, which is embedded in the mounting sleeve 100 and a portion of the surface of the metal connector 200 is exposed on the inner wall 110.

[0134] The surface of the metal connector 200 exposed on the inner wall 110 can be coplanar with the inner wall 110.

[0135] For example, the metal connector 200 can be disposed on the first connecting wall 111 or the second connecting wall 112.

[0136] The number of metal connectors 200 can be one or more. When there are multiple metal connectors 200, some of them can be disposed on the first connecting wall 111, and others on the second connecting wall 112. Alternatively, all metal connectors 200 can be disposed on the first connecting wall 111. Or, all metal connectors 200 can be disposed on the second connecting wall 112.

[0137] In this embodiment, a portion of the surface of the metal connector 200 is exposed on the inner wall 110, and the adhesive can be located between the metal connector 200 and the lens 2000. The bonding strength between the metal connector 200 and the adhesive is relatively high, thus improving the connection strength between the mounting sleeve 100 and the lens 2000.

[0138] Please see Figure 11 In some examples, the metal connector 200 may include a connecting portion 210 and a fitting portion 220, wherein the connecting portion 210 is fitted within the mounting sleeve 100, and the connecting portion 210 includes a third surface 211 and a fourth surface 212 disposed opposite to each other, wherein the third surface 211 is exposed to the inner wall 110. The fitting portion 220 is connected to the fourth surface 212 and is fitted within the mounting sleeve 100.

[0139] The number of fitting portions 220 can be one or more.

[0140] By designing the metal connector 200 to include a connecting portion 210 and a fitting portion 220, the fitting strength between the metal connector 200 and the mounting sleeve 100 can be improved, and the risk of the metal connector 200 falling off the mounting sleeve 100 can be reduced.

[0141] By providing multiple fitting portions 220 on one side of the connecting portion 210, the fitting strength between the metal connector 200 and the mounting sleeve 100 can be further improved.

[0142] Specifically, when the third surface 211 of the metal connector 200 is exposed to the first connecting wall 111, the third surface 211 is coplanar with the first connecting wall 111; when the third surface 211 of the metal connector 200 is exposed to the second connecting wall 112, the third surface 211 is coplanar with the second connecting wall 112.

[0143] Please see Figure 11 In some embodiments, a portion of the surface of the metal connector 200 is exposed to the second connecting wall 112, and the portion of the surface of the metal connector 200 exposed to the second connecting wall 112 is an arc-shaped surface.

[0144] For example, the third surface 211 is exposed to the second connecting wall 112, wherein the second connecting wall 112 is an arcuate surface, and the third surface 211 exposed to the second connecting wall 112 is also an arcuate surface, and the third surface 211 is coplanar with the second connecting wall 112.

[0145] Since the second connecting wall 112 is an arc-shaped surface, the connection between the second connecting wall 112 and the lens 2000 is relatively weak. By exposing part of the surface of the metal connector 200 to the second connecting wall 112, the second connecting wall 112 can be bonded to the lens 2000 through the metal connector 200, thereby improving the connection stability between the mounting sleeve 100 and the lens 2000.

[0146] In some examples, the metal connector 200, the first groove 140, and the second groove 150 are spaced apart along the circumferential direction S2. For example, along the circumferential direction S2, the inner wall 110 is sequentially provided with the first groove 140, at least one second groove 150, the metal connector 200, the first groove 140, at least one second groove 150, the first groove 140, and at least one second groove 150.

[0147] In some embodiments, the metal connector 200 is provided with a second groove 150 on at least one side of the mounting sleeve 100 along the axial direction L.

[0148] At this time, at least a portion of the second groove 150 and the metal connector 200 are disposed on the same connecting wall. By disposing the second groove 150 and the metal connector 200 on the same connecting wall, the bonding strength between the connecting wall and the lens 2000 can be improved. The connecting wall can be either the first connecting wall 111 or the second connecting wall 112.

[0149] For example, the metal connector 200 has at least one second groove 150 on one side of the axial direction L; or, the metal connector 200 has second grooves 150 on both sides of the axial direction L.

[0150] In some embodiments, the metal connector 200 is provided with a first groove 140 on at least one side of the mounting sleeve 100 along the axial direction L.

[0151] At this time, at least a portion of the first groove 140 and the metal connector 200 are disposed on the same connecting wall. By disposing the first groove 140 and the metal connector 200 on the same connecting wall, the bonding strength between the connecting wall and the lens 2000 can be improved. The connecting wall can be either the first connecting wall 111 or the second connecting wall 112.

[0152] For example, the metal connector 200 has a first groove 140 on one side of the mounting sleeve 100 along the axial direction L, or the metal connector 200 has a first groove 140 on each side of the mounting sleeve 100 along the axial direction L.

[0153] In some other embodiments, the metal connector 200 has a first groove 140 on one side of the mounting sleeve 100 along the axial direction L, and a second groove 150 on the other side.

[0154] The third surface 211 of the metal connector 200 can be laser-engraved to increase the roughness of the third surface 211, thereby increasing the bonding strength between the third surface 211 and the adhesive.

[0155] The third surface 211 of the metal connector 200 can also be treated with plasma to improve the cleanliness of the third surface 211, thereby improving the bonding strength between the third surface 211 and the adhesive.

[0156] Please see you later. Figure 3 and combined Figure 11 The lens module 3000 also includes a lens 2000. The lens 2000 and the inner wall 110 of the mounting sleeve 100 are bonded and fixed together with adhesive.

[0157] In some embodiments, the lens module 3000 further includes a first colloid and a second colloid. The first colloid is disposed within a groove on the first connecting wall 111 and connected to the lens 2000; the second colloid is disposed within a groove on the second connecting wall 112 and connected to the lens 2000. The groove on the first connecting wall 111 includes a first groove 140 and / or a second groove 150, and the groove on the second connecting wall 112 includes a first groove 140 and / or a second groove 150.

[0158] The modulus of the first colloid is greater than that of the second colloid.

[0159] The first colloid is formed by curing a first adhesive, and the second colloid is formed by curing a second adhesive. For example, the first adhesive can be a UV adhesive, and the second adhesive can be a UV adhesive (photosensitive adhesive).

[0160] The higher the modulus of a colloid, the greater its stiffness; conversely, the lower the modulus of a colloid, the better its elasticity.

[0161] By filling the groove on the first connecting wall 111 with a first colloid with a large modulus, the rigidity of the lens module 3000 can be improved due to the large rigidity of the first colloid.

[0162] The second connecting wall 112 is arc-shaped, which makes it prone to stress concentration. By filling the groove on the second connecting wall 112 with a second colloid with a smaller modulus, the second colloid can act as a stress buffer at the second connecting wall 112 due to its greater elasticity, thereby improving the bonding strength between the lens 2000 and the mounting sleeve 100.

[0163] In some embodiments, a locking block is provided on the outer surface of the inner wall 110 of the mounting sleeve 100 facing the lens 2000, and the locking block is located in the second groove 150.

[0164] The clip protrudes from the surface of the lens 2000 facing the inner wall 110, and the adhesive in the second groove 150 can also cover the surface of the clip. By setting the clip on the lens 2000, the contact area between the adhesive and the lens 2000 can be increased, thereby increasing the bonding strength between the lens 2000 and the mounting sleeve 100.

[0165] In some embodiments, the lens 2000 is provided with an annular groove 2001 on the outer surface of the inner wall 110 of the mounting sleeve 100. The annular groove 2001 can be used to accommodate adhesive, thereby increasing the amount of adhesive between the lens 2000 and the inner wall 110 of the mounting sleeve 100, thereby improving the bonding strength between the lens 2000 and the mounting sleeve 100 and improving the connection reliability between the lens 2000 and the lens mount 1000.

[0166] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
