Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The lens module disclosed in the present application can be used in electronic equipment, for example, the lens module is installed in a smart phone, a notebook computer, and the like. The purpose of this application is to prevent the internal structure of the electronic device and the non-visual side of the lens module from being exposed to the user's field of vision after the lens module is installed in the electronic device, thereby improving the appearance performance of the lens module. As well as improving the overall look and feel of the electronic device, which will be described in detail below.

Please refer to FIGS. 1 to 11 , the lens module includes a blocking cover 100 and a lens body 200 . The lens body 200 is the core component of the lens module, and the imaging function is realized through components such as lenses and photosensitive chips installed therein. Both the blocking cover 100 and the lens body 200 may be injection-molded, so as to save equipment cost, and the same process-forming method can also ensure the appearance consistency of the two.

Specifically, as shown in FIG. 1 and FIG. 5 , the blocking cover 100 is provided with a through hole 110 . The two opposite ends of the lens body 200 are the first mounting portion 210 and the second mounting portion 230 respectively. The first mounting portion 210 and the second mounting portion 230 are usually arranged in sequence along the direction of the optical axis of the lens module, wherein the first mounting portion 210 It is usually the head of the lens body 200, where the lens is mounted; the second mounting part 230 is usually the tail of the lens body 200, which is used to connect functional components such as a motor, and components such as a photosensitive chip are usually arranged in the second mounting part 230. In this way, ambient light will enter the second mounting portion 230 from the first mounting portion 210, thereby realizing imaging. The blocking cover 100 is sleeved on the first mounting portion 210 through the through hole 110 , so that the blocking cover 100 is mounted on the lens body 200 .

As shown in FIGS. 3 , 6 and 7 , the side of the blocking cover 100 away from the second mounting portion 230 is the first end face 101 , the side of the blocking cover 100 facing the second mounting portion 230 is the second end face 102 , and the lens body A receiving ring 220 is provided on the periphery of the 200 . The blocking cover 100 is stacked on the receiving ring 220 through the second end face 102 , so that the blocking cover 100 can be positioned along the optical axis direction of the lens module through the receiving ring 220 .

The blocking cover 100 may be made of a light-blocking material, such as a high molecular polymer such as polycarbonate; or the blocking cover 100 may also be made of a transparent material such as glass, and the blocking cover 100 may be subjected to light-blocking treatment on the surface of the blocking cover 100 by means of screen printing or the like. When the material is determined, it should also be ensured that the outer diameter of the blocking cover 100 is larger than the outer diameter of the lens body 200, so as to achieve the light blocking effect. In this way, by disposing the blocking cover 100 on the first mounting portion 210 , the blocking cover 100 can shield the lens body 200 . Specifically, the ambient light incident along the optical axis of the lens module and toward the first mounting portion 210 will be allowed to enter the second mounting portion 230 through light-transmitting elements such as lenses on the first mounting portion 210 to realize imaging; At the same time, the ambient light incident along the optical axis of the lens module and toward the first end face 101 will be blocked from entering the lens body 200 by the blocking cover 100 .

The side of the lens module facing the first end face 101 is usually the side that is visible to the user, and the side of the lens module that faces away from the second end face 102 is usually the non-visible side that the user does not want to see, so that the user When observing the lens module toward the side of the first end face 101 , the structure of the lens body 200 behind the blocking cover 100 is not exposed to the user's field of vision through the blocking of the blocking cover 100 , thereby improving the appearance performance of the lens module.

For an electronic device with a lens module installed, the overall look and feel can also be improved. Specifically, as shown in FIG. 10 , the electronic device usually includes a lens module, a protective cover 400 and an installation module 500 . The protective cover 400 is a part of the housing of the electronic device, and the lens module and the mounting module 500 are disposed inside the housing of the electronic device.

The mounting module 500 is usually a motor, a fixing bracket, etc., and the mounting module 500 is sleeved on the second mounting portion 230 to realize the positional fixation of the lens module. The protective cover 400 is usually a protective glass, the side of the first mounting portion 210 facing away from the second mounting portion 230 is the fourth end surface 212 , the protective cover 400 is disposed toward the fourth end surface 212 , and the protective cover 400 is disposed opposite to the first mounting portion 210 , to protect the lens module.

At the same time, as the protective cover 400 that protects the glass structure, the surface of the protective cover 400 is usually screen-printed to achieve light blocking, and an area is left without light blocking treatment, so that this area becomes the light-transmitting area 410, the lens body 200, The light-transmitting regions 410 can be arranged in sequence along the direction of the optical axis of the lens module, so that ambient light can enter the lens body 200 from the light-transmitting regions 410 .

The blocking cover 100 can be disposed between the transparent area 410 and the installation module 500 , and can be disposed between the transparent area 410 and the second installation portion 230 . In this way, when the user uses the electronic device, the internal structure of the electronic device, such as the installation module 500, the connection position between the installation module 500 and the second installation portion 230, cannot be exposed to the user's field of vision through the shielding of the blocking cover 100. The appearance consistency of electronic equipment has been improved, and the overall look and feel has been enhanced.

At the same time, it should be pointed out that the adhesive connection between the second mounting portion 230 and the mounting module 500 is usually realized by dispensing. Specifically, as shown in FIG. 11, the glue dispensing usually needs to be realized by the glue dispenser 600. In this way, during the assembly process, the lens body 200 can be bonded to the installation module 500 by the glue dispenser 600 first. If the blocking cover 100 is not installed, the glue dispenser 600 will not be interfered during the use process, thereby ensuring the normal assembly between the lens body 200 and the installation module 500. After the lens body 200 is fixed on the installation module 500, proceed to Installation between the cover 100 and the lens body 200 . It can be seen that the lens module adopts a split design of the cover 100 and the lens body 200, which can better avoid the assembly interference that occurs when the lens module is installed.

Further, the blocking cover 100 may be connected to the first mounting portion 210 by means of screw connection, interference connection, or the like. In the present application, the blocking cover 100 is adhered to the first mounting portion 210 by an adhesive method, so as to improve the assembly efficiency. However, by using the bonding method, it is necessary to reserve a gap between the blocking cover 100 and the first mounting portion 210 for gluing. The connection of the installation module 500, the installation module 500, etc. are exposed to the user's field of vision through the gap between the blocking cover 100 and the first installation portion 210, so the receiving ring 220 is provided for shielding. It can be seen that the setting of the receiving ring 220 can not only realize the positioning and receiving of the blocking cover 100, but also can block the gap between the blocking cover 100 and the first installation part 210, thus realizing the reuse of the receiving ring 220 . In conclusion, the mutual cooperation of the blocking cover 100 and the receiving ring 220 can further improve the appearance performance of the lens module, and can further improve the overall appearance of the electronic device.

Further, the second mounting portion 230 may be the position with the largest aperture in the lens body 200 to integrate functional modules such as a photosensitive chip, a flexible circuit board, an anti-shake mechanism, etc., and at the same time, it is easier for the second mounting portion 230 and the mounting module 500 to be connected. Assemble through the glue dispenser 600 in between.

More specifically, any cross-sectional area of the blocking cover 100 in the direction perpendicular to the optical axis of the lens module is larger than any cross-sectional area of the second mounting portion 230 in the direction perpendicular to the optical axis of the lens module, so that the lens body 200 can be realized. better occlusion.

In a further embodiment, for the case where the blocking cover 100 is glued to the first mounting part 210, a receiving cavity 300 may be provided between the blocking cover 100 and the first mounting part 210, so that the The glue can be retained in the accommodating cavity 300 , so that the blocking cover 100 can be better fixed to the first mounting portion 210 .

At the same time, a second step ring 221 may be protruded from the side of the receiving ring 220 facing the blocking cover 100 . The second step ring 221 is spaced from the first mounting portion 210 , and a first ring groove 222 is formed between the second step ring 221 and the first mounting portion 210 .

The second end surface 102 is attached to the second step ring 221 , the through hole 110 is in clearance fit with the first mounting portion 210 , a first clearance cavity 301 is formed between the through hole 110 and the first mounting portion 210 , and the accommodating cavity 300 includes a first clearance The cavity 301 and the first clearance cavity 301 are communicated with the first annular groove 222 . In this way, the glue used for bonding can be accumulated in the first gap cavity 301 and the first annular groove 222 at the same time, so that the finally formed bonding structure will enable better adhesion between the blocking cover 100 and the first mounting portion 210 Connection firmness. At the same time, it should be pointed out that under the blocking action of the second step ring 221, the glue in the first ring groove 222 can be prevented from overflowing outside the lens module, thereby avoiding the influence of the overflowing glue on the overall appearance of the lens module, and avoiding The lens module and other functional components in the electronic device are abnormally bonded.

In a further embodiment, since the first mounting portion 210 is usually used for arranging a lens, as shown in FIG. 6 and FIG. 7 , the horizontal position of the first end surface 101 may be higher than the fourth end surface 212 , and the blocking cover 100 can be easily An annular boss is formed around the lens, and the annular boss can protect the lens from being knocked.

A light hole, the ambient light can be projected onto the lens at the lens mounting hole 240 through the light transmission hole, thereby realizing imaging.

The side of the shielding ring 120 facing away from the first end surface 101 is the third end surface 103 . At this time, the junction between the third end face 103 and the fourth end face 212 is the step difference between the blocking cover 100 and the lens body 200, so that the setting of the blocking ring 120 can not only block the fourth end face 212, but also The step difference can be formed in the light-transmitting hole, so as to ensure that the side of the lens module exposed to the user's field of vision has good consistency, and further improves the look and feel.

Further, a first step ring 211 may be protruded from the fourth end surface 212 . The first step ring 211 surrounds the lens mounting hole 240 , and the part of the fourth end surface 212 for surrounding the first step ring 211 is an adhesive surface. The first part of the third end surface 103 is attached to the first step ring 211 , and the second part of the third end surface 103 is spaced from the bonding surface by the first step ring 211 .
