Description

Lens modules and electronic equipment

The present invention belongs to the field of electronic equipment technology, and in particular to a lens module and electronic equipment.

In the shooting process of mobile phones, cameras and other shooting devices, in order to ensure the final image quality, each focal length often needs to be matched with a lens and a photosensitive element, which will result in a larger size of the lens part. For small devices such as mobile phones, this setting will cause the lens module to occupy a larger space in the phone, which is not conducive to further thinning and miniaturization of mobile phones.

The present invention provides a lens module and an electronic device, which can solve the problem that the large size of the lens module restricts the further miniaturization and thinning of mobile phones.

In a first aspect, the present invention discloses a lens module, comprising a housing, and a first lens, a second lens, a first reflector, a second reflector and a photosensitive element all disposed in the housing; the housing has a first light inlet and a second light inlet, the first lens is disposed between the first light inlet and the first reflector, or the first lens is disposed between the first reflector and the photosensitive element; the first reflector can be switched between a first position and a second position; the second lens is disposed between the second light inlet and the second reflector, or the second lens is disposed between the first light inlet and the second reflector. between the second reflector and the photosensitive element; when the first reflector is located at the first position, the first reflector can be stopped between the second reflector and the photosensitive element, and the ambient light passing through the first light inlet can be transmitted through the first lens and reflected by the first reflector to reach the photosensitive element; when the first reflector is located at the second position, the first reflector can avoid the reflected light path of the second reflector, and the ambient light passing through the second light inlet can be transmitted through the second lens and reflected by the second reflector to reach the photosensitive element.

In a second aspect, the present invention discloses an electronic device including a lens module.

The present invention optimizes the lens module, specifically, a first light inlet and a second light inlet are opened on the housing, and a first lens, a second lens, a first reflector, a second reflector and a photosensitive element are arranged in the housing, wherein the first reflector can be switched between a first position and a second position.

In this way, when the first reflector is located at the first position, the first reflector can be blocked between the second reflector and the photosensitive element, and the ambient light through the first light inlet can be transmitted through the first lens and reflected by the first reflector to reach the photosensitive element.

When the first reflector is located at the second position, the first reflector can avoid the reflection light path of the second reflector, and the ambient light through the second light inlet can be transmitted through the second lens and reflected by the second reflector to reach the photosensitive element.

This method allows the first lens and the second lens to share a photosensitive element, thereby saving the manufacturing cost of the lens module, making the lens module further miniaturized, and further making the electronic equipment on which the lens module is installed further miniaturized and thinner.

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely in combination with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making progressive innovations are within the scope of protection of the present invention.

Please refer to FIG. 1 to FIG. 5 , the present invention discloses a lens module, which is usually installed in electronic devices such as mobile phones and laptops to realize the function of shooting and imaging. The lens module may include a housing 900, a first lens 100, a second lens 200, a first reflective lens 300, a second reflective lens 400 and a photosensitive element 500.

The housing 900 provides a mounting base and shielding protection for other components of the lens module. The first lens 100 , the second lens 200 , the first reflecting mirror 300 , the second reflecting mirror 400 and the photosensitive element 500 may all be disposed in the housing 900 .

The imaging principle is introduced below: the housing 900 may have a first light entrance hole 910 and a second light entrance hole 920, and the first light entrance hole 910 and the second light entrance hole 920 may enable ambient light to enter the lens module.

The first lens 100 may be disposed between the first light entrance hole 910 and the first reflective lens 300, or the first lens 100 may be disposed between the first reflective lens 300 and the photosensitive element 500. The first lens 100 is used to collect the ambient light incident from the first light entrance hole 910, and the first reflective lens 300 may be used to change the optical path to reflect the ambient light incident from the first light entrance hole 910 to the photosensitive element 500 for imaging.

The second lens 200 is disposed between the second light inlet 920 and the second reflective lens 400, or the second lens 200 is disposed between the second reflective lens 400 and the photosensitive element 500. The second lens 200 is used to collect the ambient light incident from the second light inlet 920, and the second reflective lens 400 can be used to change the optical path to reflect the ambient light incident from the second light inlet 920 to the photosensitive element 500 for imaging.

In the present invention, the first reflector 300 can be switched between the first position and the second position. The photosensitive element 500, the first reflector 300 and the second reflector 400 can be arranged in sequence along the first direction. In this way, when the first reflector 300 is located at the first position, the first reflector 300 can be blocked between the second reflector 400 and the photosensitive element 500 to block the reflected light path of the second reflector 400, and the ambient light through the first light inlet 910 can be transmitted through the first lens 100 and reflected by the first reflector 300 to reach the photosensitive element 500. When the first reflector 300 is located at the second position, the first reflector 300 can avoid the reflection light path of the second reflector 400, so that the ambient light through the second light inlet 920 can be transmitted through the second lens 200 and reflected by the second reflector 400 to reach the photosensitive element 500.

It can be seen that in the present invention, through the reflection of the second reflecting mirror 400 and the position switching of the first reflecting mirror 300, the ambient light entering through the first light inlet 910 or the ambient light entering through the second light inlet 920 can be projected onto the photosensitive element 500, thereby enabling multiple lenses to share the photosensitive element. This method can save manufacturing costs, make the lens module more miniaturized, and further make the electronic equipment on which the lens module is installed more lightweight and miniaturized.

In some optional embodiments, as shown in Figures 1 and 2, the first lens 100 is disposed between the first reflective lens 300 and the photosensitive element 500, and the second lens 200 is disposed between the second reflective lens 400 and the photosensitive element 500. For example, the second reflective lens 400, the second lens 200, the first reflective lens 300, the first lens 100 and the photosensitive element 500 are disposed in sequence.

When the first reflector 300 is located at the first position, the ambient light passing through the first light inlet 910 can be sequentially reflected by the first reflector 300 to the first lens 100, and then transmitted through the first lens 100 to the photosensitive element 500, and the lens module can achieve shooting of the first focal length through the first lens 100. The first reflector 300 can block the reflected light path of the second reflector 400, that is, in this case, the ambient light passing through the second light inlet 920 can be prevented from entering the photosensitive element 500.

When the first reflector 300 is located at the second position, the ambient light passing through the second light inlet 920 can be sequentially reflected by the second reflector 400 to the second lens 200, then transmitted to the first lens 100 through the second lens 200, and then transmitted to the photosensitive element 500 through the first lens 100. The lens module can achieve shooting at the second focal length through the combination of the second lens 200 and the first lens 100. The reflected light path of the first reflector 300 can avoid the photosensitive element 500, that is, in this case, the ambient light passing through the first light inlet 910 can be prevented from entering the photosensitive element 500.

In this embodiment, the first focal length is shorter than the second focal length. For example, when the first reflector 300 is located at the first position, the first lens 100 can realize short-focus shooting of the lens module, and when the first reflector 300 is located at the second position, the second lens 200 and the first lens 100 can constitute a combined lens, and the combined lens can realize long-focus shooting of the lens module. In other words, in this embodiment, the second lens 200 can be regarded as an extended section of the first lens 100. By changing the position of the first reflector 300, it can be selected whether to extend the first lens 100 (i.e., whether to combine the second lens 200 and the first lens 100), thereby realizing the shooting of the lens module at the first focal length or the second focal length.

In this arrangement, the first lens 100 is used as a short-focus lens, and the combination of the second lens 200 and the first lens 100 is used as a long-focus lens. In this way, the first lens 100 and the second lens 200 do not need to be equipped with more lenses, nor do they need to be longer, which saves costs.

In a more specific implementation, as shown in FIG5 , the lens module may further include a third lens 700 and a third reflective lens 800. The third reflective lens 800 may be disposed between the first lens 100 and the photosensitive element 500. A third light inlet 930 is also disposed on the housing 900, and the third lens 700 is disposed between the third light inlet 930 and the third reflective lens 800. For example, the third light inlet 930, the third lens 700 and the third reflective lens 800 are sequentially disposed along a direction parallel to the second direction.

The third reflector 800 can be switched between the fifth position and the sixth position. When the third reflector 800 is in the fifth position, the reflected light path of the first reflector 300 is blocked from being projected to the photosensitive element 500, and the reflected light path of the second reflector 400 is blocked from being projected to the photosensitive element 500. At this time, the ambient light passing through the third light inlet 930 is sequentially transmitted through the third lens 700 and reflected by the third reflector 800 and projected to the photosensitive element 500, so that the lens module can achieve the fifth focal length shooting through the third lens 700.

When the third reflector 800 is located at the sixth position, the third reflector 800 will avoid the reflection light path of the first reflector 300 and the reflection light path of the second reflector 400, and the shooting module can shoot at the first focal length or the second focal length. At the same time, the reflection light path of the third reflector 800 can avoid the photosensitive element 500 to prevent the ambient light through the third light inlet 930 from being projected onto the photosensitive element 500.

In some other optional implementation schemes, as shown in Fig. 6, the third lens 700 and the third reflective lens 800 may also be disposed between the first lens 100 and the photosensitive element 500. The third lens 700 is disposed between the third reflective lens 800 and the photosensitive element 500, for example, the second reflective lens 400, the second lens 200, the first reflective lens 300, the first lens 100, the third reflective lens 800, and the third lens 700 are disposed in sequence.

When the third reflector 800 is located at the fifth position, the ambient light passing through the third light inlet 930 will be reflected by the third reflector 800 and transmitted through the third lens 700 to reach the photosensitive element 500, so as to perform the sixth focal length shooting. The third reflector 800 can block the reflected light path of the first reflector 300 from entering the photosensitive element 500, and block the reflected light path of the second reflector 400 from entering the photosensitive element 500, so as to prevent the ambient light of the first light inlet 910 and the ambient light of the second light inlet 920 from being projected onto the photosensitive element 500.

When the third reflector 800 is located at the sixth position, the third reflector 800 can avoid the reflection light path of the first reflector 300 and the reflection light path of the second reflector 400 to avoid interfering with the ambient light projected to the photosensitive element 500 through the first light inlet 910 or the second light inlet 920. At the same time, the reflection light path of the third reflector 800 can avoid the photosensitive element 500 to avoid the ambient light projected to the photosensitive element 500 through the third light inlet 930. In this case, the light path transmitted through the first lens 100 can be transmitted through the third lens 700 to reach the photosensitive element 500.

Specifically, when the first reflector 300 is located at the first position and the third reflector 800 is located at the sixth position, the ambient light passing through the first light inlet 910 can be reflected by the first reflector 300, transmitted by the first lens 100 and transmitted by the third lens 700 in sequence to reach the photosensitive element 500. At this time, the first lens 100 and the third lens 700 cooperate with each other to form a combined lens to complete the shooting of the seventh focal length. When the first reflector 300 is located at the second position and the third reflector 800 is located at the sixth position, the ambient light passing through the second light inlet 920 can be reflected by the second reflector 400, transmitted by the second lens 200, transmitted by the first lens 100 and transmitted by the third lens 700 in sequence to reach the photosensitive element 500. At this time, the second lens 200, the first lens 100 and the third lens 700 cooperate with each other to form a combined lens to complete the shooting of the eighth focal length. In this case, the first lens 100 can be regarded as the first extended section of the third lens 700, and the second lens 200 can be regarded as the second extended section of the third lens 700. The third lens 700 can be adaptively extended according to the change of the shooting distance to complete the shooting of different focal lengths.

It can be seen that this layout will give the lens module more imaging possibilities and meet the shooting needs of more focal lengths.

In some other optional embodiments, as shown in FIG. 3 and FIG. 4 , the first lens 100 may be disposed between the first light entrance hole 910 and the first reflective mirror 300 , and the second lens 200 may be disposed between the second light entrance hole 920 and the second reflective mirror 400 .

In this embodiment, the photosensitive element 500, the first reflector 300 and the second reflector 400 are arranged in sequence along the first direction, and the first light inlet 910, the first lens 100 and the first reflector 300 are arranged in a direction parallel to the second direction, and the second light inlet 920, the second lens 200 and the second reflector 400 are arranged in a direction parallel to the second direction. The second direction and the first direction can be 90° to each other.

In this way, when the first reflector 300 is located at the first position, the ambient light passing through the first light inlet 910 can be sequentially transmitted through the first lens 100 to the first reflector 300, and then reflected by the first reflector 300 to reach the photosensitive element 500, and the lens module can achieve the third focal length shooting through the first lens 100. At the same time, the first reflector 300 can block the reflected light path of the second reflector 400 from entering the photosensitive element 500, so as to prevent the ambient light passing through the second light inlet 920 from reaching the photosensitive element 500.

When the first reflector 300 is located at the second position, the ambient light passing through the second light inlet 920 can be transmitted through the second lens 200 to the second reflector 400, and then reflected by the second reflector 400 to reach the photosensitive element 500, and the lens module can achieve the fourth focal length shooting through the second lens 200. At this time, the reflection light path of the first reflector 300 can avoid the photosensitive element 500 to prevent the ambient light passing through the first light inlet 910 from being projected onto the photosensitive element 500.

In this embodiment, by changing the position of the first reflective lens 300, the first lens 100 can be used to shoot at the third focal length, or the second lens 200 can be used to shoot at the fourth focal length. Since the third focal length is shorter than the fourth focal length, the second lens 200 has a longer length and more lenses than the first lens 100, so that it can be used as a telephoto lens, while the first lens 100 can be used as a short focal length lens. In this way, the first lens 100 and the second lens 200 each realize independent shooting functions to meet different shooting requirements.

In a more specific implementation, the third lens 700, the third reflective mirror 800 and the third light inlet 930 may also adopt the arrangement shown in FIG. 7 . Specifically, the third reflective mirror 800 may be disposed between the first reflective mirror 300 and the photosensitive element 500 , and the third lens 700 may be disposed between the third light inlet 930 and the third reflective mirror 800 .

When the third reflector 800 is located at the fifth position, the ambient light passing through the third light inlet 930 will be sequentially transmitted through the third lens 700 and reflected by the third reflector 800 to reach the photosensitive element 500, so as to achieve shooting at the ninth focal length. The third reflector 800 can block the reflected light path of the first reflector 300 from entering the photosensitive element 500, and block the reflected light path of the second reflector 400 from entering the photosensitive element 500, so as to prevent the ambient light passing through the first light inlet 910 and the second light inlet 920 from being projected onto the photosensitive element 500.

When the third reflector 800 is located at the sixth position, the third reflector 800 can avoid the reflection light path of the first reflector 300 and the reflection light path of the second reflector 400, so that the reflection light path of the first reflector 300 or the reflection light path of the second reflector 400 can reach the photosensitive element 500 to avoid interference with the light entering the photosensitive element 500 through the first light inlet 910 and the ambient light entering the photosensitive element 500 through the second light inlet 920, thereby ensuring the shooting of the third focal length and the fourth focal length. At the same time, the reflection light path of the third reflector 800 can avoid the photosensitive element 500 to avoid the ambient light through the third light inlet 930 from being projected onto the photosensitive element 500.

This arrangement can further enrich the shooting mode of the lens module to achieve shooting at more focal lengths. It should be noted here that the third lens 700, the third reflector 800 and the third light inlet 930 are not limited to the arrangement of Figures 5 to 7. At the same time, multiple third lenses 700 can be arranged in the lens module. Correspondingly, each third lens 700 needs to be configured with a corresponding third reflector 800 and third light inlet 930, so as to further enrich the shooting mode of the lens module and achieve shooting at more focal lengths. This will not be described in detail here.

Furthermore, in the above arrangement, the first light entrance hole 910, the second light entrance hole 920 and the third light entrance hole 930 can all be arranged on the same side of the housing 910, for example, they are all rear cameras of a mobile phone or front cameras of a mobile phone, etc., to facilitate the layout of imaging.

Furthermore, the lens module may also include a driving element. The driving element drives and connects the first reflector 300. The driving element may drive the first reflector 300 to switch between the first position and the second position. For example, the driving element is a rotary motor, and the first reflector 300 is axially connected to the motor shaft of the rotary motor, so that the first reflector 300 can achieve angle change through rotational motion, thereby switching between the first position and the second position. For another example, the driving element may be a translation mechanism, such as a piston mechanism, and the first reflector 300 is connected to the piston rod of the piston mechanism, so that the first reflector 300 can switch between the first position and the second position through translational motion.

The driving element of the present invention is shown in Figures 1 to 4, and the driving element includes a power member 610, a connecting rod 620 and a slide groove 630. The first reflector 300 is provided with a first limiting pin 310 and a first connecting portion 320, and the first connecting portion 320 and the first limiting pin 310 are arranged at intervals.

The two ends of the connecting rod 620 are rotatably connected to the power member 610 and the first connecting portion 320, respectively, and the first limit pin 310 is movably arranged in the slide groove 630. For example, the power member 610 is a motor, and the connecting rod 620 is connected to the motor shaft of the motor. The first connecting portion 320 is a hole, and the end of the connecting rod 620 is provided with a shaft rotatably connected to the hole.

The driving member 610 can drive the connecting rod 620 to rotate, and the first reflector 300 can drive the first limiting pin 310 to move in the slide groove 630 as the connecting rod 620 rotates. The first reflector 300 can switch between the first position and the second position as the connecting rod 620 rotates and the first limiting pin 310 moves.

This arrangement enables the power member 610, the connecting rod 620, the first reflector 300 and the slide groove 630 to form a crank slider mechanism, and the first reflector 300 is the middle rocker of the crank slider mechanism. The power member 610 provides power to drive the first reflector 300 to move through the connecting rod 620, and the first limit pin 310 rotates to connect the connecting rod 620, and the sliding fit between the first connecting part 320 and the slide groove 630 can constrain the movement path of the first reflector 300, thereby realizing the switching of the first reflector 300 between the first position and the second position.

Furthermore, the slide groove 630 may have a first limiting end and a second limiting end. For example, the slide groove 630 is configured as a waist-shaped groove, the first limiting end and the second limiting end are arc segments at both ends of the waist-shaped groove, and the first limiting pin 310 may be a cylindrical pin to achieve smooth sliding in the slide groove 630.

In this structure, the driving member 610 can drive the connecting rod 620 to rotate, and the first reflector 300 can rotate along with the connecting rod 620, driving the first limit pin 310 to move between the first limit end and the second limit end. When the first limit pin 310 moves to the first limit end, the first reflector 300 is in the first position. When the first limit pin 310 moves to the second limit end, the first reflector 300 is in the second position.

It can be seen that the provision of the first limiting end and the second limiting end can limit the first limiting pin 310, thereby preventing the first reflecting mirror 300 from deviating from the first position or the second position due to excessive movement.

Furthermore, the lens module may further include a block 1000. The block 1000 is disposed in the housing 900 and may be limitedly matched with the first reflector 300. The block 1000 has a blocking effect on the movement of the first reflector 300. For example, the block 1000 may be disposed on a side of the first reflector 300 away from the first light inlet 910, so that when the first reflector 300 moves to the second position, the block 1000 may prevent the first reflector 300 from continuing to move and deviating from the second position. For another example, the block 1000 may be disposed on a side of the first reflector 300 facing the first light inlet 910, so that when the first reflector 300 moves to the first position, the block 1000 can prevent the first reflector 300 from continuing to move and deviating from the first position.

The block 1000 cooperates with the first limiting end and the second limiting end to ensure that the first reflecting mirror 300 can accurately move to the first position and the second position, thereby improving the movement accuracy of the first reflecting mirror 300.

Similarly, the third reflector 800 may also be equipped with a driving element. Specifically, a third limiting pin 810 and a third connecting portion 820 may be arranged at intervals on the third reflector 800, wherein the two ends of the connecting rod 620 are rotatably connected to the third connecting portion 820 and the power member 610, respectively, and the third limiting pin 810 is movably arranged in the slide groove 630. This arrangement can also realize the driving of the third reflector 800 to move and control the movement path of the third reflector 800. A block 1000 may also be arranged on the third reflector 800 to improve the overall movement accuracy.

Furthermore, the photosensitive element 500 may include a filter and a photosensitive wafer. The filter is an optical device that can filter stray light, and the photosensitive wafer is a core component of the photosensitive element 500 to achieve imaging. This arrangement can improve imaging quality.

The electronic device disclosed in the embodiments of the present invention may be a mobile phone, a tablet computer, an e-book reader, a wearable device (such as a smart watch, smart glasses), etc. The embodiments of the present invention do not limit the specific types of electronic devices.

The above is only an embodiment of the present invention and is not intended to limit the present invention. For those with ordinary knowledge in the field, the present invention can be modified and varied in various ways. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the patent application of the present invention.
