Description

Technical Field

[0001] The present application relates to the technical field of filter assembly, and in particular to a filter assembly, a camera module and a terminal. Background Art

[0002] At present, in camera modules, the filter is usually glued to the bracket by glue. However, when the camera module is impacted, such as when it falls, the bracket transfers stress to the filter, causing the filter to crack due to the large stress, thereby affecting the stability of the camera module. Utility Model Content

[0003] In view of the above, it is necessary to propose a filter assembly, a camera module and a terminal to reduce the stress on the filter when the camera module is subjected to impact force and ensure the stability of the camera module.

[0004] The present application provides a filter assembly, including:

[0005] A bracket, the bracket comprising a first surface, a second surface disposed opposite to the first surface, and a side ring surface connected between the first surface and the second surface, the bracket being provided with a light-through hole penetrating the first surface and the second surface, the side ring surface being provided with at least two notches, each of the notches penetrating the first surface and the second surface, and the opening direction of each of the notches being oriented in a direction away from the light-through hole;

[0006] A filter, disposed on the first surface of the bracket, wherein the edge of the filter covers a portion of the structure of each of the notches;

[0007] A first colloid, bonded between the first surface of the bracket and the filter;

[0008] The second colloid is bonded to the second surface of the bracket and is used for bonding to external components.

[0009] The above-mentioned filter assembly reduces the contact area between the bracket and the edge of the filter by opening at least two notches on the side ring surface of the bracket, thereby reducing the stress transmitted from the bracket to the edge of the filter, making the stress on the edge of the filter smaller, and reducing the stress on the filter when the camera module is subjected to impact force. Since the stress on the edge of the filter is reduced, the filter is not easy to crack, thereby ensuring the stability of the camera module.

[0010] In one embodiment, the side ring surface includes a first side surface, a second side surface, a third side surface and a fourth side surface which are connected end to end in sequence, and the first side surface, the second side surface, the third side surface and the fourth side surface are respectively connected to the first surface and the second surface, so that the bracket forms a first side, a second side, a third side and a fourth side.

[0011] The filter assembly mentioned above makes the bracket roughly rectangular ring-shaped by limiting the specific surface shape of the side ring surface. The structure of the bracket is simple and easy to manufacture.

[0012] In one embodiment, at least two of the notches are spaced apart and located on any one of the first side, the second side, the third side and the fourth side of the bracket, or at least two of the notches are respectively located on at least two of the first side, the second side, the third side and the fourth side of the bracket.

[0013] The above-mentioned filter assembly, by limiting the spacing of at least two notches located on the same side of the bracket, only needs to open the notches on the same side of the bracket, which is conducive to shortening the production cycle and improving production efficiency; by opening notches on at least two sides of the bracket, the bracket reduces the magnitude of the stress transmitted to at least two sides of the filter, so that the stress on the periphery of the filter can be reduced, further making the filter less likely to crack, thereby ensuring the stability of the camera module.

[0014] In one embodiment, a cross-sectional area of ​​the filter parallel to the first surface is smaller than an area of ​​the first surface.

[0015] The filter assembly limits the cross-sectional area of ​​the filter to be smaller than the area of ​​the first surface, so that the edge of the bracket and the edge of the filter are staggered, avoiding the edge of the bracket from directly transferring stress to the edge of the filter, making the filter less likely to crack.

[0016] In one embodiment, the opening size of the notch gradually increases from an end close to the light-through hole to an end far from the light-through hole.

[0017] The above-mentioned filter assembly is easy to open by limiting the opening size of the notch to gradually increase from the end close to the light-through hole to the end far away from the light-through hole, and the contact surface between the edge of the filter corresponding to the notch and the bracket also gradually increases from the end close to the light-through hole to the end far away from the light-through hole, thereby reducing the contact area between the edge of the bracket and the edge of the filter.

[0018] In one embodiment, the bracket is further provided with an air escape hole that penetrates the first surface and the second surface and is connected to the light-through hole, the edge of the filter partially covers the air escape hole, and the first colloid avoids the air escape hole and is bonded between the first surface of the bracket and the filter.

[0019] The above-mentioned filter assembly, by providing the above-mentioned escape holes, can allow air to circulate inside and outside the filter assembly. When the filter assembly is applied to a camera module, it can ensure that the positive and negative pressures in the space enclosed by the filter and the bracket remain balanced, thereby avoiding damage to other components due to unstable positive and negative pressures.

[0020] In one embodiment, the bracket further has a protruding portion extending from the side ring surface in a direction away from the light-through hole.

[0021] The filter assembly, by providing the protruding portion, improves the structural strength of the support and the bonding strength between the support and the second colloid.

[0022] In one embodiment, the second colloid includes a base glue, a side ring glue and at least two embedded glues, one side of the base glue is bonded to the second surface of the bracket, the side ring glue is vertically connected to the periphery of one side of the base glue and is bonded to the side ring surface of the bracket, at least two embedded glues correspond to at least two notches one by one, each embedded glue is connected to the side of the side ring glue facing the side ring surface and embedded in the corresponding notch, and the height of the side ring glue and the height of the embedded glue are both smaller than the height of the bracket.

[0023] The filter assembly, by limiting the specific structure of the second colloid, can effectively wrap the bracket by the second colloid, thereby improving the bonding strength between the second colloid and the bracket.

[0024] An embodiment of the present application also provides a camera module, comprising a filter assembly as described in any of the above technical solutions.

[0025] In the filter assembly of the above-mentioned camera module, at least two notches are opened on the side ring surface of the bracket to reduce the contact area between the bracket and the edge of the filter, thereby reducing the stress transmitted from the bracket to the edge of the filter, so that the stress on the edge of the filter is reduced, and the stress on the filter when the camera module is subjected to impact force is reduced. Since the stress on the edge of the filter is reduced, the filter is not easy to crack, thereby ensuring the stability of the camera module.

[0026] An embodiment of the present application also provides a terminal, comprising the camera module as described in the above technical solution.

[0027] In the filter assembly of the camera module of the above-mentioned terminal, at least two notches are provided on the side ring surface of the bracket to reduce the contact area between the bracket and the edge of the filter, thereby reducing the stress transmitted from the bracket to the edge of the filter, so that the stress on the edge of the filter is reduced, and the stress on the filter when the terminal is subjected to impact force is reduced. Since the stress on the edge of the filter is reduced, the filter is not easy to crack, thereby ensuring the stability of the camera module of the terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0063] See also Figure 1 The first embodiment of the present application provides a filter assembly 100. The filter assembly 100 of this embodiment can reduce the stress transmitted by the bracket 10 to the filter 20 when subjected to impact such as falling or collision, so that the filter 20 is not prone to cracking.

[0064] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the filter assembly 100 includes a bracket 10 , a filter 20 , a first colloid 30 and a second colloid 40 .

[0065] The bracket 10 has a first surface 11, a second surface 12 disposed opposite to the first surface 11, and a side ring surface 13 connected between the first surface 11 and the second surface 12. The first surface 11 and the second surface 12 are both substantially planes. The bracket 10 is substantially plate-shaped. The bracket 10 is provided with a light-through hole 14 penetrating the first surface 11 and the second surface 12. The side ring surface 13 of the bracket 10 is provided with at least two notches 15, each of which penetrates the first surface 11 and the second surface 12, and the opening direction of each notch 15 is toward a direction away from the light-through hole 14. Specifically, in this embodiment, the bracket 10 is roughly rectangular ring-shaped, and the side ring surface 13 includes a first side surface 131, a second side surface 132, a third side surface 133 and a fourth side surface 134 connected end to end in sequence, and the first side surface 131, the second side surface 132, the third side surface 133 and the fourth side surface 134 are respectively connected to the first surface 11 and the second surface 12, so that the bracket 10 forms a first side 101, a second side 102, a third side 103 and a fourth side 104. Among them, the notch 15 can be understood as being opened on one or more of the first side 101, the second side 102, the third side 103 and the fourth side 104 of the bracket 10, and the first side 101, the second side 102, the third side 103 and the fourth side 104 can be understood as being formed by combining the edge of the first surface 11, the edge of the second surface 12 and the side ring surface 13. It can be understood that by setting the bracket 10 to be roughly rectangular ring-shaped, the structure of the bracket 10 is simple and easy to manufacture.

[0066] The filter 20 is disposed on the first surface 11 of the bracket 10 . The cross-sectional area of ​​the filter 20 parallel to the first surface 11 is smaller than the area of ​​the first surface 11 . The edge of the filter 20 covers a portion of the structure of each notch 15 .

[0067] The first colloid 30 is bonded between the first surface 11 of the bracket 10 and the filter 20, and the cross-sectional area of ​​the first colloid 30 is smaller than the cross-sectional area of ​​the filter 20. The first colloid 30 may be BG glue.

[0068] The second colloid 40 is glued to the second surface 12 of the bracket 10. The second colloid 40 is used to glue to external components, for example, the second colloid 40 is used to glue to a circuit board (not shown) in a camera module (not shown). The second colloid 40 may be LHA glue.

[0069] The above filter assembly 100, by opening at least two notches 15 on the side annular surface 13 of the bracket 10, the edge of the filter 20 covers part of the structure of each notch 15, and reduces the contact area between the bracket 10 and the edge of the filter 20. Since the contact area between the edge of the filter 20 and the bracket 10 is reduced, when the bracket 10 is subjected to impact force, such as falling, the stress transmission path can be reduced, thereby reducing the magnitude of the stress transmitted from the bracket 10 to the edge of the filter 20, so that the stress on the edge of the filter 20 is reduced, and the stress on the filter 20 when the camera module is subjected to impact force is reduced. Since the stress on the edge of the filter 20 is reduced, the filter 20 is not easy to crack, and the stability of the camera module is ensured. It can be understood that the filter 20 is usually more likely to crack when its edge is subjected to stress. In addition, by limiting the cross-sectional area of ​​the filter 20 to be smaller than the cross-sectional area of ​​the bracket 10, the bracket 10 protects the filter 20, and the edge of the bracket 10 is staggered with the edge of the filter 20 to avoid the edge of the bracket 10 directly transferring stress to the edge of the filter 20, making it less likely for the filter 20 to crack.

[0070] In this embodiment, the bracket 10 is provided with two notches 15, and the two notches 15 are spaced apart and located at the first side 101 of the bracket 10, wherein one of the notches 15 is located at a position on the first side 101 close to the second side 102, and the other notch 15 is located at a position on the first side 101 close to the fourth side 104. In this way, by limiting the two notches 15 to be spaced apart and located at the first side 101 of the bracket 10, it is only necessary to open the notch 15 at the first side 101 of the bracket 10, which is conducive to shortening the manufacturing cycle and improving production efficiency; and limiting the two notches 15 to be located at a position on the first side 101 close to the second side 102 and at a position on the first side 101 close to the fourth side 104, respectively, to reduce the contact area between the bracket 10 and the corners of the filter 20, and further reduce the magnitude of the stress transmitted by the bracket 10 to the corners of the filter 20.

[0071] It is understandable that in other embodiments, the two notches 15 may be spaced apart from each other on the second side 102 , the third side 103 , or the fourth side 104 .

[0072] It is understandable that in other embodiments, three, four or more notches 15 may be provided on the side annular surface 13 of the bracket 10 , and the three, four or more notches 15 are provided at intervals on the first side 101 , the second side 102 , the third side 103 or the fourth side 104 .

[0073] In this embodiment, the opening size of each notch 15 gradually increases from the end close to the light through hole 14 to the end far from the light through hole 14. In this way, by limiting the opening size of the notch 15 to gradually increase from the end close to the light through hole 14 to the end far from the light through hole 14, the notch 15 is easy to open, and the contact surface between the edge of the filter 20 corresponding to the notch 15 and the bracket 10 also gradually increases from the end close to the light through hole 14 to the end far from the light through hole 14, thereby reducing the contact area between the edge of the bracket 10 and the outermost edge of the filter 20.

[0074] In this embodiment, the second side 102 of the bracket 10 is also provided with an air escape hole 16 that penetrates the first surface 11 and the second surface 12 and is connected to the light hole 14. The edge of the filter 20 covers part of the structure of the air escape hole 16. The first colloid 30 avoids the air escape hole 16 and is bonded between the first surface 11 of the bracket 10 and the filter 20. In this way, by providing the above-mentioned air escape hole 16, the air escape hole 16 can allow air to circulate inside and outside the filter assembly 100. When the filter assembly 100 is applied to the camera module, it can ensure that the positive and negative pressures in the space enclosed by the filter 20, the bracket 10 and the circuit board of the camera module are balanced, thereby avoiding damage to other components such as a photosensitive chip (not shown) due to unstable positive and negative pressures.

[0075] The third side 103 of the bracket 10 also has a protrusion 17 extending from the third side surface 133 of the side annular surface 13 in a direction away from the light-through hole 14, and the air escape hole 16 extends into the protrusion 17. In this way, by providing the above-mentioned protrusion 17, the size of the air escape hole 16 can be increased, and the strength of the structure of the bracket 10 where the air escape hole 16 is opened can be enhanced. Among them, the size of the protrusion 17 gradually decreases from the second side surface 132 of the side annular surface 13 in a direction away from the light-through hole 14, thereby reducing the weight of the filter assembly 100.

[0076] It is understandable that in other embodiments, the air escape hole 16 and the protrusion 17 may also be disposed on the second side 102 or the fourth side 104 of the bracket 10. The air escape hole 16 and the protrusion 17 and the notch 15 need to be located on different sides of the bracket 10.

[0077] In this embodiment, the third side 103 of the bracket 10 further has a protruding portion 18 extending from the third side surface 133 of the side annular surface 13 in a direction away from the light-through hole 14, and the protruding portion 18 is spaced apart from the protruding portion 17. Thus, by providing the protruding portion 18, the structural strength of the bracket 10 is improved, and the bonding strength between the bracket 10 and the second colloid 40 is improved.

[0078] It is understandable that the protruding portion 18 may also be disposed on the second side 102 or the fourth side 104 , and the air escape hole 16 and the protruding portion 17 may be disposed on different sides of the bracket 10 from the protruding portion 18 .

[0079] In this embodiment, the second colloid 40 includes a base glue 41, a side ring glue 42 and two embedded glues 43. One side of the base glue 41 is bonded to the second surface 12 and the protrusion 17 of the bracket 10, the side ring glue 42 is vertically connected to the periphery of one side of the base glue 41 and is bonded to the side ring surface 13 of the bracket 10, and is bonded to the protrusion 18, the two embedded glues 43 correspond to the two notches 15 one by one, each embedded glue 43 is connected to the side of the side ring glue 42 facing the side ring surface 13 and embedded in the corresponding notch 15, the height of the side ring glue 42 and the height of the embedded glue 43 are both less than the height of the bracket 10, that is, they are also less than the height of the notch 15. In this way, by limiting the specific structure of the second colloid 40, the second colloid 40 can effectively wrap the bracket 10 and improve the bonding strength between the second colloid 40 and the bracket 10. It can be understood that the shape of the second colloid 40 is compatible with the shape of the bracket 10.

[0080] It can be understood that in other embodiments, when the number of the notches 15 is three, four or more, the number of the embedded glue 43 is also correspondingly three, four or more.

[0081] See also Figure 5The second embodiment of the present application provides a filter assembly 200. The structure of the filter assembly 200 provided in this embodiment is substantially similar to that of the filter assembly 100 provided in the first embodiment, except that, in this embodiment, four notches 15 are provided on the side annular surface 13 of the bracket 10, two of which are spaced apart on the first side 101 of the bracket 10 and are respectively located on the first side 101 near the second side 102 and on the first side 101 near the fourth side 104, and the other two notches 15 are spaced apart on the second side 102 of the bracket 10 and are respectively located on the second side 102 near the first side 101 and on the second side 102 near the third side 103. Correspondingly, the number of the embedded glue 43 of the second colloid 40 is also four. In this way, by providing two notches 15 on the first side 101 and the second side 102 of the bracket 10, the bracket 10 can reduce the stress transmitted to the two edges of the filter 20, so that the stress on the periphery of the filter 20 can be reduced, and the filter 20 is further less likely to crack, thereby ensuring the stability of the camera module.

[0082] It can be understood that in other embodiments, five notches 15 can be provided on the side annular surface 13 of the bracket 10, wherein two notches 15 are spaced apart and located on the first side 101 of the bracket 10, two more notches 15 are spaced apart and located on the second side 102 of the bracket 10, and the last notch 15 is located on the fourth side 104 of the bracket 10. Accordingly, the number of the embedded glue 43 of the second colloid 40 is also five. This embodiment will not be described in detail.

[0083] See also Figure 6 , the third embodiment of the present application provides a filter assembly 300. The structure of the filter assembly 300 provided in this embodiment is roughly similar to that of the filter assembly 100 provided in the first embodiment, except that, in this embodiment, the first colloid 30 is a waterproof and breathable glue, which can be specifically silicone glue. By setting the first colloid 30 to be a waterproof and breathable glue, the waterproof and breathable glue can allow air to circulate inside and outside the filter assembly 300. When the filter assembly 300 is applied to a camera module, it can ensure that the positive and negative pressures in the space enclosed by the filter 20, the bracket 10 and the circuit board of the camera module remain balanced, thereby avoiding damage to other components such as photosensitive chips due to unstable positive and negative pressures. In this way, for example, the escape hole 16 and the protrusion 17 described in the first embodiment can be omitted.

[0084] It can be understood that in other embodiments, for example, eight notches 15 can be provided on the side ring surface 13 of the bracket 10, and two notches 15 are provided on the first side 101, the second side 102, the third side 103 and the fourth side 104. Correspondingly, the number of embedded glue 43 of the second colloid 40 is also eight, and this embodiment does not make any specific limitation on this.

[0085] It can be understood that in other embodiments, the bracket 10 can also be roughly annular, and the first colloid 30 is a waterproof and breathable glue, and two notches 15 are provided on the side ring surface 13 of the bracket 10. In this way, by limiting the bracket 10 to be roughly annular, it is helpful to reduce the cross-sectional area of ​​the bracket 10, thereby reducing the area of ​​the filter assembly 300, which helps to achieve a miniaturized design of the camera module.

[0086] The fourth embodiment of the present application provides a camera module (not shown). The camera module includes the filter assembly 100, 200, 300 as described in any of the above embodiments. The embodiment of the present application is described by taking the filter assembly 100 described in the first embodiment as an example. It can be understood that the camera module can also include components such as a circuit board, a photosensitive chip, a lens, and a motor. For example, the filter assembly 100 is bonded to the circuit board through the second colloid 40, the photosensitive chip is electrically connected to the circuit board and is located in the space enclosed by the bracket 10, the filter 20 and the circuit board, the motor is electrically connected to the circuit board and is sleeved on the filter assembly 100, and the lens is arranged in the motor and is arranged opposite to the filter assembly 100.

[0087] In the above-mentioned camera module, in its filter assembly 100, two notches 15 are opened on the side ring surface 13 of the bracket 10, and the edge of the filter 20 covers part of the structure of the notch 15, thereby reducing the contact area between the bracket 10 and the edge of the filter 20. Since the contact area between the edge of the filter 20 and the bracket 10 is reduced, when the bracket 10 is subjected to impact force, such as falling, the stress transmission path can be reduced, thereby reducing the magnitude of the stress transmitted from the bracket 10 to the edge of the filter 20, so that the stress on the edge of the filter 20 is reduced, and the stress on the filter 20 when the camera module is subjected to impact force is reduced. Since the stress on the edge of the filter 20 is reduced, the filter 20 is not easy to crack, thereby ensuring the stability of the camera module.

[0088] The fifth embodiment of the present application provides a terminal (not shown). The terminal includes the camera module as described in the fifth embodiment above, and the camera module can be a rear camera of the terminal. The terminal can be a mobile phone, a tablet computer, a smart watch, a sweeping robot, a car lens, a VR device, an AR device, or other devices with a camera function.

[0089] In the filter assembly 100 of the camera module of the above-mentioned terminal, two notches 15 are opened on the side ring surface 13 of the bracket 10, and the edge of the filter 20 covers part of the structure of the notch 15, thereby reducing the contact area between the bracket 10 and the edge of the filter 20. Since the contact area between the edge of the filter 20 and the bracket 10 is reduced, when the bracket 10 is subjected to impact force, such as the terminal falling or colliding, the stress transmission path can be reduced, thereby reducing the magnitude of the stress transmitted from the bracket 10 to the edge of the filter 20, so that the stress on the edge of the filter 20 is reduced, and the stress on the filter 20 when the terminal is subjected to impact force is reduced. Since the stress on the edge of the filter 20 is reduced, the filter 20 is not easy to crack, thereby ensuring the stability of the camera module of the terminal.

[0090] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
