However, due to the long and narrow circuit board and the large number of components arranged on the circuit board, the circuit boards on both sides of the lens are prone to breakage and damage, affecting the stability and durability of the camera. Utility Model Content

[0003] In view of the above, it is necessary to propose a camera module and electronic device for a notebook computer to improve the stability and durability of the camera module.

[0004] The present application provides a camera module for a notebook computer, comprising:

[0005] A circuit board, used for electrical connection with external devices;

[0010] In one embodiment, the protective shell is in a ring shape, and the lens is located in a space enclosed by the protective shell.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0051] See also Figure 1 The first embodiment of the present application provides a camera module 100 for a notebook computer. The camera module 100 for a notebook computer includes a circuit board 10, a lens 20, a protective shell 30 and a reinforcing member 40.

[0052] Specifically, the circuit board 10 is used to be electrically connected to an external device. For example, the circuit board 10 can be electrically connected to electrical components such as a processor, a battery, and a memory. The lens 20 is disposed on the circuit board 10, and the lens 20 is used to acquire an image. The protective shell 30 is disposed on the circuit board 10 and is spaced apart from the lens 20, wherein a plurality of electrical components can be disposed in the protective shell 30, and the protective shell 30 is used to protect the electrical components therein to prevent dust from entering. The reinforcement 40 is disposed between the lens 20 and the protective shell 30, and the reinforcement 40 is connected to the lens 20, the circuit board 10, and the protective shell 30, respectively.

[0053] In this way, the camera module 100 for the laptop computer mentioned above, by setting the reinforcement member 40 between the lens 20 and the protective shell 30, and the reinforcement member 40 is respectively connected to the lens 20, the circuit board 10 and the protective shell 30, so that the thickness of the circuit board 10 on the side of the lens 20 can be increased, so that the circuit board 10 on the side of the lens 20 is more resistant to bending and not easy to break, thereby enhancing the stability and durability of the camera module 100, reducing the possibility of failure or damage of the camera module 100 during use, and improving the safety of the use of the camera module 100.

[0054] In this embodiment, the number of protective shells 30 can be two, each protective shell 30 is roughly in the shape of a cuboid, and the two protective shells 30 are respectively arranged on both sides of the lens 20 in a direction perpendicular to the optical axis of the lens 20. The number of reinforcing members 40 is two and they are arranged one-to-one corresponding to the two protective shells 30, and each reinforcing member 40 is respectively connected to the lens 20, the circuit board 10 and the corresponding protective shell 30. In this way, by limiting the provision of two protective shells 30, the thickness of the circuit board 10 on both sides of the lens 20 is increased, and the stability and durability of the camera module 100 are further enhanced.

[0055] Furthermore, each protective shell 30 is provided with an air escape hole 32, so that the interior of the protective shell 30 is connected with the exterior of the protective shell 30, and the air escape hole 32 can be provided on the top surface and / or the side surface of the protective shell 30, and can also be provided at the corner of the protective shell 30. In this way, by providing the air escape hole 32 on the protective shell 30, the interior of the protective shell 30 is connected with the exterior of the protective shell 30, and the positive and negative pressure balance of the electrical components in the protective shell 30 is ensured, thereby ensuring the stable use of the electrical components in the protective shell 30.

[0056] In this embodiment, the reinforcing member 40 is formed by curing glue, and the glue may be acrylic resin. Thus, by limiting the reinforcing member 40 to be formed by curing glue, the reinforcing member 40 can be arranged by filling the glue between the lens 20 and the protective shell 30 and curing the glue, and the reinforcing member 40 is easy to operate and use, and is convenient for large-scale production and application; in addition, the acrylic resin glue can be cured quickly, which can reduce production time and reduce costs.

[0057] It is understandable that in other embodiments, the reinforcing member 40 may also be a metal member, which is welded between the lens 20, the protective shell 30 and the circuit board 10. Alternatively, the reinforcing member 40 may also be an object with a colloid on the surface, the three surfaces of the object have the colloid and the three surfaces of the object with the colloid are respectively glued to the lens 20, the circuit board 10 and the protective shell 30. Alternatively, the reinforcing member 40 may be integrally formed with the circuit board 10, the two opposite sides of the reinforcing member 40 respectively have the colloid, and the reinforcing member 40 is respectively connected to the lens 20 and the protective shell 30 through the colloid on both sides thereof. Alternatively, the reinforcing member 40 may also be other objects that can be connected between the lens 20, the protective shell 30 and the circuit board 10.

[0058] Please refer to Figure 2 In this embodiment, the lens 20 includes a lens barrel 22 and a lens group 24. The lens barrel 22 is disposed on the circuit board 10 and is spaced apart from the protective shell 30. The lens group 24 is disposed in the lens barrel 22. The lens group 24 may include one, two, three or more lenses. The reinforcing member 40 is connected to the lens barrel 22, the circuit board 10 and the protective shell 30, respectively. In this way, by setting the above-mentioned specific structure of the lens 20, the reinforcing member 40 is connected to the lens barrel 22 of the lens 20, so as to avoid the reinforcing member 40 and the lens group 24 from being connected and contaminating the lens group 24, thereby ensuring the normal use of the lens 20.

[0059] It can be understood that the lens 20 can also include devices such as filters (not shown in the figure), photosensitive elements (not shown in the figure), and drive motors (not shown in the figure). The filters, photosensitive elements, drive motors and other devices can be integrated with the lens group 24 and then set in the lens barrel 22. The embodiments of the present application will not be repeated here.

[0060] Furthermore, the lens barrel 22 includes a connecting member 222 and a threaded member 224, the connecting member 222 is roughly quadrilateral-shaped, the threaded member 224 is roughly toroidal-shaped, the size of the threaded member 224 is smaller than the size of the connecting member 222, the projection of the threaded member 224 on the circuit board 10 is roughly the inner circle of the projection of the connecting member 222 on the circuit board 10, the connecting member 222 is arranged on the circuit board 10 and is spaced apart from the protective shell 30, the threaded member 224 is arranged on the side of the connecting member 222 away from the circuit board 10, the connecting member 222 and the threaded member 224 are both hollow structures and are connected, the threaded member 224 has an internal thread, the lens group 24 has an external thread, and the lens group 24 is threadedly connected to the threaded member 224, wherein the reinforcement member 40 is respectively connected to the connecting member 222, the circuit board 10 and the protective shell 30. In this way, by configuring the lens barrel 22 to include the above-mentioned connecting member 222 and the screw member 224 , the connecting member 222 is connected to the reinforcing member 40 , thereby improving the connection strength between the reinforcing member 40 and the lens 20 .

[0061] Please refer to Figure 3In this embodiment, the ratio of the thickness t1 of the reinforcing member 40 along the optical axis of the lens 20 to the thickness t2 of the connecting member 222 along the optical axis of the lens 20 is in the range of 0.5 to 1, for example, 0.5, 0.6, 0.7, 0.8, 0.9, 1, etc. In this way, by limiting the ratio range of the thickness of the reinforcing member 40 to the thickness of the connecting member 222, the connection strength between the connecting member 222 and the reinforcing member 40 is guaranteed. However, when the ratio of t1 to t2 is less than 0.5, the thickness of the reinforcing member 40 is relatively thin, and the bonding strength of the glue is insufficient, resulting in poor durability of the camera module 100; when the ratio of t1 to t2 is greater than 1, the glue is not thoroughly cured, and bubbles or other hollowing phenomena are easily generated inside, resulting in poor durability of the camera module 100, and more glue is likely to contaminate the lens group 24, affecting the shooting effect of the camera module 100.

[0062] In this embodiment, the thickness t1 of the reinforcing member 40 along the optical axis of the lens 20 is smaller than the thickness t3 of the protective shell 30 along the optical axis of the lens 20. Thus, by limiting the thickness t1 of the reinforcing member 40 to be smaller than the thickness t3 of the protective shell 30, the reinforcing member 40 is prevented from covering or blocking the vent hole 32 of the protective shell 30, thereby interfering with the protective shell 30, thereby ensuring the stable use of the protective shell 30.

[0063] See also Figure 4 The second embodiment of the present application provides a camera module 200 for a laptop computer. The structure of the camera module 200 for a laptop computer provided in this embodiment is roughly similar to the structure of the camera module 100 for a laptop computer provided in the first embodiment, except that: in this embodiment, the number of the protective shell 30 is one, the number of the reinforcing member 40 is also one, the protective shell 30 is arranged at an interval with the lens 20, and the reinforcing member 40 is respectively connected to the connecting member 222 of the lens 20, the circuit board 10 and the protective shell 30. In this way, the reinforcing member 40 is respectively connected to the lens 20, the circuit board 10 and the protective shell 30, and the thickness of the circuit board 10 on the side of the lens 20 is increased, so that the circuit board 10 on the side of the lens 20 is more resistant to bending and not easy to break, thereby enhancing the stability and durability of the camera module 200, reducing the possibility of failure or damage of the camera module 200 during use, and improving the safety of the camera module 200.

[0064] It can be understood that in other embodiments, the number of protective shells 30 can be more, and accordingly, the number of reinforcing members 40 can also be more, which can be set according to actual conditions.

[0065] See also Figure 5The third embodiment of the present application provides a camera module 300 for a laptop computer. The structure of the camera module 300 for a laptop computer provided in this embodiment is roughly similar to the structure of the camera module 100 for a laptop computer provided in the first embodiment, except that: in this embodiment, the protective shell 30 is roughly annular, the lens 20 is located in the space enclosed by the protective shell 30, and the reinforcing member 40 is a continuous annular structure. The reinforcing member 40 is connected to the connecting member 222 of the lens 20, the circuit board 10 and the protective shell 30 respectively by filling glue between the protective shell 30 and the lens 20 and curing the glue (UV light irradiation curing). In this way, by setting the above-mentioned shapes of the protective shell 30 and the reinforcing member 40, the thickness of the lens 20 around the circuit board 10 is increased, and the stability and durability of the camera module 300 are further enhanced.

[0066] See also Figure 6 The fourth embodiment of the present application provides a camera module 400 for a laptop computer. The structure of the camera module 400 for a laptop computer provided in this embodiment is roughly similar to the structure of the camera module 300 for a laptop computer provided in the third embodiment, except that: in this embodiment, the protective shell 30 is roughly annular, the lens 20 is located in the space enclosed by the protective shell 30, and the reinforcing member 40 is a non-continuous annular structure, that is, glue is applied to multiple locations between the protective shell 30 and the lens 20 by dispensing, so that the reinforcing member 40 formed by the curing of the glue at multiple locations is respectively connected to the connector 222 of the lens 20, the circuit board 10 and the protective shell 30. It can be understood that the glue at multiple locations is cured and formed to form a non-continuous annular structure together. In this way, by setting the above-mentioned shapes of the protective shell 30 and the reinforcing member 40, the thickness of the entire circumference of the lens 20 at the circuit board 10 can still be increased, further enhancing the stability and durability of the camera module 400.

[0067] See also Figure 7The fifth embodiment of the present application provides an electronic device 1, which includes the camera module 100, 200, 300, 400 for a laptop computer as described in any one of the first to fourth embodiments.
