Description

Technical Field

[0001] The present application relates to the technical field of lens modules, and in particular to a lens module and an electronic device. Background Art

[0002] In recent years, with the gradual popularization of portable electronic devices such as mobile phones, tablets, and laptops, users have higher and higher requirements for the experience of electronic devices, especially the quality requirements of camera lenses.

[0003] Most camera lenses include structures such as brackets and optical elements. In order to monitor whether the optical elements fall off or break, transparent conductive wires, such as indium tin oxide conductive wires, are usually set on the optical elements. The resistance change of the transparent conductive wires is monitored to judge the condition of the optical elements. During the manufacturing process, the optical elements and brackets are usually connected by glue dispensing. However, in the process of realizing this application, the inventors found that there are at least the following problems in the prior art: Since the colloid has fluid characteristics, it is easy to deform and difficult to control. In the actual glue dispensing process, problems such as insufficient glue and overflowing glue often occur, resulting in an unstable connection between the optical element and the bracket, and the optical element is prone to fall off, or even cause a short circuit. Summary of the invention

[0004] In view of the above, it is necessary to propose a lens module and an electronic device to solve the above problems.

[0005] The present application provides a lens module, comprising:

[0006] A bracket, comprising a barrel and a mounting body, the barrel having a first connecting end and a second connecting end opposite to each other, the barrel being provided with a receiving cavity penetrating the first connecting end and the second connecting end, the inner wall of the receiving cavity extending in a direction close to the optical axis to form a mounting body, the mounting body having a first surface and a second surface opposite to each other, the second surface being located in the receiving cavity, the mounting body being provided with a light-through hole penetrating the first surface and the second surface, a glue-dispensing hole penetrating the first surface and the second surface being provided on a peripheral side of the light-through hole, and the glue-dispensing hole being spaced apart from the light-through hole;

[0007] A first optical element is disposed in the receiving cavity and corresponding to the second surface; the first optical element covers the light hole along the optical axis direction;

[0008] A transparent conductive line, disposed on a side of the first optical element close to the second surface;

[0009] The colloid is arranged in the dispensing hole and is used for connecting the first optical element and the second surface of the mounting body.

[0010] In this way, glue is applied to the glue dispensing hole by glue dispensing to form a colloid, and the transparent conductive wire, the first optical element and the second surface of the mounting body are connected by the colloid. The flow of the colloid is guided by the glue dispensing hole, and the shape and position of the colloid are restricted. The condition of the colloid can be observed through the glue dispensing hole, so as to remedy the condition of insufficient glue. Furthermore, the colloid is contained in the glue dispensing hole to prevent the colloid from falling off due to accidental contact.

[0011] In some embodiments of the present application, the second surface has a limiting groove, the glue dispensing hole passes through the bottom of the limiting groove, and the cross-sectional dimension of the limiting groove along the direction perpendicular to the optical axis is larger than the cross-sectional dimension of the glue dispensing hole along the direction perpendicular to the optical axis.

[0012] In this way, by making the cross-sectional dimension of the limiting groove larger than the cross-sectional dimension of the glue dispensing hole, the cross-sectional shape of the colloid along the optical axis direction is roughly T-shaped, so as to increase the contact area between the colloid and the transparent conductive wire, the first optical element and the mounting body, so as to enhance the firmness of the combination between the transparent conductive wire, the first optical element and the mounting body and prevent the colloid from falling off.

[0013] In one embodiment of the present application, the cross-sections of the glue dispensing hole and the limiting groove are both circular, the radius range of the glue dispensing hole is 0.3mm to 0.5mm, and the radius range of the limiting groove is 0.6mm to 1.0mm.

[0014] In this way, by setting the radius difference between the dispensing hole and the limiting groove, the cross-sectional difference of the colloid in the dispensing hole and the limiting groove is limited, so as to improve the stability of the colloid.

[0015] In one embodiment of the present application, the first surface has a groove, the glue dispensing hole runs through the bottom of the groove, and the cross-sectional dimension of the groove along the direction perpendicular to the optical axis is larger than the cross-sectional dimension of the glue dispensing hole along the direction perpendicular to the optical axis.

[0016] In this way, the groove, the dispensing hole and the limiting groove are matched to make the cross-section of the colloid along the optical axis roughly I-shaped, so as to enhance the bonding force between the colloid and the mounting body and prevent the colloid from falling off. Furthermore, the cross-sectional size of the groove is larger, which is convenient for dispensing operations.

[0017] In one embodiment of the present application, the cross-section of the groove is circular, and the radius of the groove ranges from 0.6 mm to 0.8 mm.

[0018] Thus, the circular groove is easy to manufacture, and the radius of the groove is limited so that the colloid in the groove of the first surface is in the shape of a round pancake with a cross section larger than the size of the colloid in the dispensing hole, so as to enhance the bonding force between the colloid and the mounting body.

[0019] In one embodiment of the present application, the lens module further includes a metal kit adapted to the shape of the glue dispensing hole, and an outer side wall of the metal kit is connected to a side wall of the glue dispensing hole.

[0020] In this way, the colloid can be guided to penetrate into the bottom of the dispensing hole through the metal sleeve, thereby enhancing the stability and reliability between the colloid and the transparent conductive wire, the first optical element and the mounting body.

[0021] In some embodiments of the present application, the distance between the metal kit and the transparent conductive line along the optical axis direction ranges from 0.04 mm to 0.06 mm.

[0022] In this way, this distance can ensure that the colloid penetrates into the bottom of the dispensing hole and enhance the stability of the colloid adhesion.

[0023] In some embodiments of the present application, the colloid is conductive, and the lens module further includes:

[0024] A conductive base connected to the second connecting end;

[0025] A conductive member, comprising a first end, a second end and an extension portion, wherein the extension portion connects the first end and the second end, the extension portion is embedded in the cylinder, the first end is electrically connected to the conductive base, the second end is electrically connected to the metal kit, and the metal kit is electrically connected to the transparent conductive wire through the colloid;

[0026] The circuit board is arranged on a side of the conductive base away from the bracket.

[0027] In this way, by embedding the extension portion of the conductive element in the barrel, it is prevented that the lens module is manually operated to touch and damage the conductive element.

[0028] In one embodiment of the present application, the lens module further includes:

[0029] A carrier, disposed in the receiving cavity, the carrier having a receiving hole coaxial with the light-through hole, and the first optical element is disposed on a side of the carrier close to the first surface;

[0030] The second optical element is disposed in the receiving hole and adjacent to the first optical element.

[0031] In this way, the first optical element is supported by the carrier and the second optical element is supported, and the first optical element and the second optical element process the light emitted or received by the lens module in sequence.

[0032] The present application also provides an electronic device, comprising the lens module as described in the above embodiment.

[0033] In this way, the lens module of the electronic device is glued in the glue dispensing hole by glue dispensing to form a colloid, and the transparent conductive wire, the first optical element and the mounting body are connected by the colloid. The flow of the colloid is guided by the glue dispensing hole, the shape and position of the colloid are restricted, and the condition of the colloid can be observed through the glue dispensing hole, so as to remedy the condition of insufficient glue. Furthermore, the colloid is contained in the glue dispensing hole to prevent the colloid from falling off due to accidental contact. BRIEF DESCRIPTION OF THE DRAWINGS

The lens module 10 comprises a transmitting unit 1 and a receiving unit 2, wherein the transmitting unit 1 is used to transmit light to an object to be photographed, and the receiving unit 2 is used to receive light reflected by the object to be photographed.

[0077] It can be understood that the present application only takes the lens module 10 as an example. In other embodiments, the lens module 10 may only include the transmitting unit 1 or the receiving unit 2, or the lens module 10 may only include a partial structure of the transmitting unit 1 or the receiving unit 2.

[0078] Please also see Figures 2 to 4 The emitting unit 1 includes a bracket 11, a first optical element 12, a transparent conductive line 13 and a colloid 14. The bracket 11 includes a barrel 111 and a mounting body 112. The barrel 111 has a first connecting end 1111 and a second connecting end 1112 opposite to each other. The barrel 111 is provided with a receiving cavity 1113 penetrating the first connecting end 1111 and the second connecting end 1112. The inner wall of the receiving cavity 1113 extends in a direction close to the optical axis to form the mounting body 112. The mounting body 112 is connected to the first connecting end 1111. The mounting body 112 has a first surface 1121 and a second surface 1122 opposite to each other. The second surface 1122 is located in the receiving cavity 1113. The mounting body 112 is provided with a first surface 1121 and a second surface 1122 penetrating the first surface 1121 and the second surface 1122. A light-through hole 1123 is provided with a glue-dispensing hole 1124 penetrating the first surface 1121 and the second surface 1122 on its circumferential side, and the glue-dispensing hole 1124 is spaced apart from the light-through hole 1123; the first optical element 12 is disposed in the receiving cavity 1113 and is disposed corresponding to the second surface 1122; the first optical element 12 covers the light-through hole 1123 along the optical axis direction; the transparent conductive line 13 is disposed on one side of the first optical element 12 close to the second surface 1122; glue can be applied to the glue-dispensing hole 1124 by glue-dispensing to form a colloid 14, and the colloid 14 is used to connect the first optical element 12 and the second surface 1122 of the mounting body 112.

[0079] In this way, the emitting unit 1 of the lens module 10 of the embodiment of the present application applies glue to the glue hole 1124 by glue dispensing to form the colloid 14, and the first optical element 12 and the mounting body 112 are connected by the colloid 14. The flow of the colloid 14 is guided by the glue hole 1124, and the shape and position of the colloid 14 are restricted. The condition of the colloid 14 can be observed through the glue hole 1124, so as to remedy the condition of insufficient glue. Furthermore, the colloid 14 is contained in the glue hole 1124 to prevent the colloid 14 from falling off due to accidental contact.

[0080] In this embodiment, the barrel 111 and the mounting body 112 are integrally provided. For example, the barrel 111 and the mounting body 112 of the bracket 11 may be formed by injection molding or the like.

[0081] In other embodiments, the first surface 1121 and the second surface 1122 of the mounting body 112 are both located in the receiving cavity 1113 , that is, the mounting body 112 can be formed as long as the inner wall of the barrel 111 extends in a direction close to the optical axis.

[0082] In one embodiment, the height of the colloid 14 is less than the depth of the dispensing hole 1124 to prevent the colloid 14 from affecting the appearance when it is higher than the dispensing hole 1124, and the exposed colloid 14 is easily touched, thereby affecting the firmness between the transparent conductive line 13, the first optical element 12 and the mounting body 112.

[0083] In one embodiment of the present application, the first optical element 12 is a diffractive optical element.

[0084] In one embodiment, the material of the transparent conductive line 13 includes indium tin oxide. An indium tin oxide circuit can be fabricated on the first optical element 12, and the change in resistance of the indium tin oxide circuit can be sensed to determine whether the first optical element 12 is detached or broken.

[0085] In one embodiment of the present application, the colloid 14 is directional and is a conductive colloid. In addition to connecting the transparent conductive wire 13, the first optical element 12 and the mounting body 12, the colloid 14 is also used to achieve electrical connection between the transparent conductive wire 13 and the circuit board. In other embodiments, the colloid 14 is insulating and is a non-conductive colloid. The transparent conductive wire 13 and the circuit board are electrically connected in other ways, such as a transparent conductive wire embedded in the bracket 11 connecting the circuit board and the transparent conductive wire 13.

[0086] In one embodiment of the present application, the colloid 14 may be conductive silver paste.

[0087] In one embodiment of the present application, the barrel 111 is substantially cylindrical. In other embodiments, the barrel 111 may be in other shapes, such as a square.

[0088] In this embodiment, the mounting body 112 is in a plate shape.

[0089] In this embodiment, the first surface 1121 is flush with the first connecting end 1111 . In other embodiments, the mounting body 112 may be disposed in the receiving cavity 1113 .

[0090] In this embodiment, the light hole 1123 is located at the center of the mounting body 112 and communicates with the receiving cavity 1113. There are two glue holes 1124, which are arranged opposite to each other along the optical axis and spaced apart from the light hole 1123. In other embodiments, the number of glue holes 1124 may be greater than two.

[0091] In this embodiment, the first optical element 12 has an effective area and an ineffective area, wherein the effective area is used to pass effective light, the light-through hole 1123 is arranged corresponding to the effective area of ​​the first optical element 12, and the glue hole 1124 is arranged corresponding to the ineffective area of ​​the first optical element 12.

[0092] Please see again Figure 3 The second surface 1122 has a limiting groove 1125, and the glue hole 1124 runs through the bottom of the limiting groove 1125. The cross-sectional dimension of the limiting groove 1125 along the direction perpendicular to the optical axis is larger than the cross-sectional dimension of the glue hole 1124 along the direction perpendicular to the optical axis.

[0093] In this way, the cross-sectional dimension of the limiting groove 1125 is larger than the cross-sectional dimension of the dispensing hole 1124, so that the cross-sectional shape of the colloid 14 along the optical axis direction is roughly T-shaped, so as to increase the contact area between the colloid 14 and the transparent conductive wire 13, the first optical element 12 and the mounting body 112, so as to enhance the firmness between the transparent conductive wire 13, the first optical element 12 and the mounting body 112. Furthermore, the contact area between the T-shaped colloid 14 and the outside (i.e., the first surface 1121) is small, and the volume inside the bracket 11 (i.e., the second surface 1122 side) is large, so as to enhance the stability of the colloid 14 and prevent the colloid 14 from falling off.

[0094] In one embodiment of the present application, the cross-sections of the glue dispensing hole 1124 and the limiting groove 1125 are both circular, and the radius of the glue dispensing hole 1124 ranges from 0.3mm to 0.5mm, and the radius of the limiting groove 1125 ranges from 0.6mm to 1.0mm. In this way, by the radius difference between the limiting groove 1125 and the glue dispensing hole 1124, the colloid in the limiting groove 1125 is roughly in the shape of a round cake, and the colloid in the glue dispensing hole 1124 is roughly in the shape of a cylinder, and the two parts of the colloid have a radius difference, so as to improve the stability of the colloid 14. At the same time, the circular glue dispensing hole 1124 and the limiting groove 1125 are easy to manufacture and accept.

[0095] In one embodiment, a microstructure (not shown) is provided on the inner wall of the dispensing hole 1124 or the limiting groove 1125, wherein the microstructure may be a groove or a protrusion. The contact area between the colloid 14 and the mounting body 112 may be increased through the microstructure, so as to enhance the bonding force between the colloid 14 and the mounting body 112 and strengthen the stability of the bonding between the colloid 14 and the mounting body 112.

[0096] In one embodiment of the present application, the depth range of the limiting groove 1125 along the optical axis direction is 0.05mm to 0.1mm, and the thickness of the limiting groove 1125 largely limits the thickness of the colloid 14. Therefore, the thickness of the colloid 14 reaches more than 0.05mm to ensure that the colloid 14 has a certain adhesion, thereby enhancing the stability between the transparent conductive wire 13, the first optical element 12 and the mounting body 112.

[0097] In one embodiment of the present application, the first surface 1121 has a groove 1126, and the glue hole 1124 runs through the bottom of the groove 1126. The cross-sectional dimension of the groove 1126 along the direction perpendicular to the optical axis is larger than the cross-sectional dimension of the glue hole 1124 along the direction perpendicular to the optical axis.

[0098] In this way, through the cooperation of the groove 1126, the glue dispensing hole 1124 and the limiting groove 1125, the cross-section of the colloid 14 along the optical axis direction is roughly I-shaped, so as to enhance the bonding force between the colloid 14 and the mounting body 112, prevent the colloid 14 from falling off, and improve the service life of the colloid 14. Furthermore, the cross-sectional size of the groove 1126 is larger, which is convenient for glue dispensing operations.

[0099] In one embodiment of the present application, the height of the colloid 14 is less than the depth of the groove 1126 to prevent the colloid 14 from affecting the appearance when it is higher than the groove 1126, and the exposed colloid 14 from being easily touched, thereby affecting the firmness between the transparent conductive line 13, the first optical element 12 and the mounting body 112.

[0100] In one embodiment of the present application, the cross-section of the groove 1126 is circular, and the radius range of the groove 1126 is: 0.6mm~0.8mm, wherein the circular groove 1126 is easy to manufacture, and the radius of the groove 1126 is limited so that the colloid 14 in the groove 1126 of the first surface 1121 is in the shape of a round pancake and the cross-section is larger than the size of the colloid 14 in the glue dispensing hole 1124, so as to enhance the bonding force between the colloid 14 and the mounting body 112.

[0101] In one embodiment of the present application, the depth range of the groove 1126 along the optical axis direction is: 0.2mm~0.4mm, and the depth range of the glue hole 1124 along the optical axis direction is 0.1mm~0.15mm. The length of the colloid 14 is limited by the depth of the groove 1126 and the depth of the glue hole 1124 to ensure the bonding force between the colloid 14 in the groove 1126 and the glue hole 1124 and the mounting body 112.

[0102] In one embodiment of the present application, the emitting unit 1 also includes a metal kit 15, which is adapted to the shape of the glue dispensing hole 1124, and the outer wall of the metal kit 15 is connected to the side wall of the glue dispensing hole 1124. In this way, the colloid 14 can be guided by the metal kit 15 to penetrate into the bottom of the glue dispensing hole 1124, thereby enhancing the stability and reliability between the colloid 14 and the transparent conductive wire 13, the first optical element 12 and the mounting body 112.

[0103] In this embodiment, the metal sleeve 15 is in a ring shape and can be formed in the dispensing hole 1124 by insert molding technology.

[0104] In one embodiment of the present application, the distance between the metal sleeve 15 and the transparent conductive wire 13 along the optical axis direction ranges from 0.04 mm to 0.06 mm. This distance can ensure that the colloid 14 penetrates into the bottom of the dispensing hole 1124 and enhance the stability of the adhesion of the colloid 14.

[0105] In one embodiment of the present application, the material of the metal sleeve 15 can be conductive metal such as copper and silver.

[0106] In one embodiment of the present application, the emitting unit 1 also includes a conductive base 16, a conductive member 17 and a circuit board 18. The conductive base 16 is connected to the second connection end 1112. The circuit board 18 is arranged on the side of the conductive base 16 away from the bracket 11. The conductive member 17 includes an extension portion 171, a first end 172 and a second end 173. The extension portion 171 connects the first end 172 and the second end 173. The extension portion 171 is embedded in the cylinder 111.
