DETAILED DESCRIPTION

[0025] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0026] Currently, the lens module and the entire camera are usually assembled by screws in the related art. However, during the screw tightening process, the structural stability of the lens is affected, thereby affecting the imaging quality of the camera.

[0027] For example, a camera in the related art includes a lens module and a camera body. The lens module includes a lens and a lens mount. Multiple lens elements are disposed within the lens, and threads are provided on the outer surface of the lens, connecting the lens and the lens mount via the threads. The lens mount is provided with multiple screw holes, allowing the lens module to be assembled to the camera body using screws, thereby completing the assembly of the entire camera. During the screw tightening process, the lens is subjected to stress transmitted from the lens mount. Localized stress on the lens can cause slight changes in the structural stability of the lens, which can affect the lens's precision and thus reduce the camera's imaging quality.

[0028] To address the above technical issues, the present application provides a lens module with a buffer structure disposed between the lens body and the lens mount. The buffer structure absorbs stress transmitted from the lens mount to the lens body. This effectively reduces stress within the lens body, preventing local stress on the lens body from causing changes in the lens' structural stability, and improving the precision of the lens body, thereby effectively enhancing the camera's imaging effect and quality.

[0029] An exemplary embodiment of the present application provides a lens module, such as Figure 1 As shown, the lens module 1 includes a lens body 11 and a lens holder 12. Figure 2 and Figure 3A buffer structure 13 is provided between the lens body 11 and the lens holder 12. Exemplarily, the buffer structure 13 can be a structure formed on the lens body 11 or the lens holder 12 that can play a buffering role, or it can be a buffer member such as silicone provided between the lens body 11 and the lens holder 12. As long as it can play a buffering role to absorb the stress transmitted from the lens holder 12 to the lens body 11, this embodiment does not make any specific limitation on this.

[0030] The buffer structure 13 absorbs the stress transmitted from the lens mount 12 to the lens body 11. Such a design can effectively reduce the stress inside the lens body 11, avoid changes in the structural stability of the lens 112 caused by local stress on the lens body 11, and improve the accuracy of the lens body 11, thereby effectively improving the imaging effect of the camera and improving the imaging quality of the camera.

[0031] Combine Figure 3 In one embodiment, the lens body 11 includes a lens barrel 111 and a plurality of lenses 112 disposed within the lens barrel 111. The plurality of lenses 112 may be, for example, 2, 4, 5, 7, 9, etc., and may be specifically configured according to the pixels required to be achieved by the camera. By configuring the plurality of lenses 112 within the lens barrel 111, the pixel count of the camera can be increased, thereby facilitating improved imaging quality. The buffer structure 13 is disposed on the lens barrel 111. For example, the buffer structure 13 may be disposed on the outer surface of the lens barrel 111, on the inner surface of the lens barrel 111, or inside the lens barrel 111.

[0032] The buffer structure 13 can absorb stress transmitted from the lens base 12 to at least one lens 112. For example, the buffer structure 13 can absorb stress transmitted from the lens base 12 to one lens 112, such as the lens 112 closest to the connection between the lens base 12 and the lens barrel 111; the buffer structure 13 can also absorb stress transmitted from the lens base 12 to some of the multiple lenses 112, such as some of the lenses 112 near the screw holes at the connection between the lens base 12 and the lens barrel 111; and the buffer structure 13 can also absorb stress transmitted from the lens base 12 to each lens 112.

[0033] With this arrangement, on the one hand, arranging the buffer structure 13 on the lens barrel 111 not only facilitates the arrangement of the buffer structure 13, but also brings the buffer structure 13 closer to each lens 112, effectively isolating the force path of the lens barrel 111 and preventing the stress transmitted from the lens base 12 to the lens barrel 111 from being further transmitted to each lens 112, thereby reducing the sensitivity of the lens body 11, that is, preventing the structural stability of multiple lenses 112 from changing due to the local stress of the lens module 1, improving the stability of the position of each lens 112, and thus improving the accuracy of the lens body 11, further improving the imaging quality of the camera. On the other hand, by absorbing the stress transmitted from the lens base 12 to at least one lens 112 through the buffer structure 13, the sensitivity of the lens body 11 is further reduced, and the stability of the position of each lens 112 is effectively improved, which is conducive to further improving the imaging quality of the camera.

[0034] Illustratively, in this embodiment, multiple lenses 112 can be fixed in the lens barrel 111, for example, by glue dispensing; or stepped limiting protrusions can be provided on the inner wall of the lens barrel 111, for example, multiple annular limiting protrusions are provided on the inner surface of the lens barrel 111, and along the axial direction of the lens barrel 111, the inner diameters of the multiple annular limiting protrusions from the first end of the lens barrel 111 to the second end can be gradually reduced, or gradually increased, or first reduced and then increased, or first increased and then reduced; multiple lenses 112 can also be fixed in the lens barrel 111, for example, by stacking and squeezing each other, and can then be reinforced by glue dispensing or the like.

[0035] Combine Figure 3 In one embodiment, the lens barrel 111 includes a first barrel section 113 for connecting to the lens base 12, and the connection and fixation between the lens barrel 111 and the lens base 12 is achieved through the outer barrel wall of the first barrel section 113. For example, the outer barrel wall of the first barrel section 113 and the lens base 12 can be screwed together by threads, thereby improving the convenience of assembly while ensuring the stability of the connection between the lens barrel 111 and the lens base 12, thereby helping to improve the reliability of the camera. It should be noted that during screw installation, excessive rotation may occur (for example, it should be rotated 2 turns, but due to the operator's error, it is rotated two and a half turns), which will generate stress on one or more lenses 112 and affect the resolution of the lenses. The buffer structure 13 of the present application can absorb stress and avoid affecting the resolution of the lenses.

[0036] In other embodiments, the outer wall of the first barrel section 113 and the lens holder 12 may be connected by snap fasteners or other means, thereby further improving the ease of assembly of the camera. The outer wall of the first barrel section 113 and the lens holder 12 may also be connected by gluing or other means, which is not specifically limited.

[0037] A buffer cavity 1131 is provided within the wall of the first barrel section 113, and the buffer cavity 1131 constitutes the buffer structure 13. This arrangement, on the one hand, simplifies the arrangement of the buffer structure 13 and facilitates production and processing, thereby improving the production efficiency of the camera. When the lens module 1 is assembled as a whole, the buffer cavity 1131 provided within the wall of the first barrel section 113 can effectively isolate the path of force applied to the lens barrel 111, effectively releasing stress through the buffer structure 13, and preventing the stress transmitted from the lens base 12 to the lens barrel 111 from being further transmitted to the individual lenses 112, thereby reducing the sensitivity of the lens body 11. Furthermore, by providing the buffer cavity 1131 within the wall of the first barrel section 113 to constitute the buffer structure 13, it is also possible to avoid affecting the connection between the first barrel section 113 and the lens base 12, thereby improving the assembly accuracy between the first barrel section 113 and the lens base 12, thereby not only improving the reliability of the camera, but also improving the camera's sophistication, thereby enhancing the user experience. In addition, the buffer structure 13 adopts the above-mentioned configuration, which can also avoid increasing the volume of the lens body 11, making the structure of the lens module 1 more compact, thereby facilitating the miniaturization design of the camera.

[0038] For example, in this embodiment, the buffer cavity 1131 can be disposed within the wall of the first barrel section 113 and does not penetrate the wall surface of the first barrel section 113. This can improve the structural strength of the first barrel section 113, thereby further enhancing the reliability of the camera. The buffer cavity 1131 can also be disposed within the wall of the first barrel section 113 and penetrate the outer surface of the first barrel section 113, such as the end face or the wall surface. This can facilitate the processing of the buffer cavity 1131 and improve the buffering effect, thereby improving the imaging effect of the camera.

[0039] Combine Figure 3 In one embodiment, the end surface of the first barrel section 113 is concavely provided with a groove, and the inner cavity of the groove constitutes a buffer cavity 1131. It is understandable that the lens barrel 111 also includes a second barrel section connected to the first barrel section 113. The first barrel section 113 and the second barrel section are an integrally formed one-piece structure. Along the axial direction of the first barrel section 113, the first barrel section 113 includes a first end surface connected to the second barrel section and a second end surface opposite to the first end surface. The groove is provided on the second end surface and is recessed from the second end surface along the axial direction of the first barrel section 113 toward the first end surface.

[0040] Such a setting not only facilitates the processing of the buffer cavity 1131, making the structure of the lens barrel 111 simple, thereby improving the production efficiency of the camera, but also makes the buffer cavity 1131 correspond to the connection between the lens holder 12 and the first barrel section 113, thereby effectively isolating the force path of the lens barrel 111, thereby reducing the sensitivity of the lens body 11, and improving the stability of the setting position of each lens 112, which is conducive to further improving the imaging quality of the camera.

[0041] Combine Figure 4 In another embodiment, the buffer cavity 1131 extends along the circumferential direction of the lens barrel 111 to surround the lens 112 in the lens barrel 111. This design can effectively improve the comprehensiveness of the buffer cavity 1131 in isolating stress, thereby further reducing the sensitivity of the lens body 11 and improving the imaging quality of the camera.

[0042] Combine Figure 3 and Figure 4 In another embodiment, the end surface of the first barrel section 113 is concavely provided with a groove, the inner cavity of the groove forming the buffer structure 13. At the same time, the buffer cavity 1131 extends along the circumferential direction of the lens barrel 111 to surround the lens 112 in the lens barrel 111. This arrangement, on the one hand, not only facilitates the processing of the buffer cavity 1131, simplifies the structure of the lens barrel 111, thereby improving the production efficiency of the camera, but also makes the buffer cavity 1131 correspond to the connection between the lens base 12 and the first barrel section 113, thereby effectively isolating the force path of the lens barrel 111, thereby reducing the sensitivity of the lens body 11 and improving the stability of the position of each lens 112, thereby further improving the imaging quality of the camera. On the other hand, it can also effectively improve the comprehensiveness of the buffer cavity 1131 in isolating stress, thereby further reducing the sensitivity of the lens body 11 and improving the imaging quality of the camera.

[0043] Combine Figure 4 In one embodiment, along the radial direction of the lens barrel 111, the groove includes a first groove wall 1132 and a second groove wall 1133 that are opposite to each other. Along the circumference of the lens barrel 111, at least one reinforcing rib 114 is disposed in the groove. For example, along the circumference of the lens barrel 111, only one reinforcing rib 114 may be disposed in the groove, or multiple reinforcing ribs 114, such as two, four, six, or eight, may be disposed. The multiple reinforcing ribs 114 may be dispersed or evenly distributed along the circumference of the lens barrel 111.

[0044] The reinforcing rib 114 is connected to the bottom of the groove, the first groove wall 1132, and the second groove wall 1133. This arrangement effectively improves the structural strength of the lens barrel 111 and prevents the first barrel section 113 of the lens barrel 111 from breaking when connected to the lens base 12. This ensures that the stress transmitted from the lens base 12 to the at least one lens 112 is absorbed by the buffer structure 13, thereby improving the imaging quality of the camera and further enhancing the reliability of the camera, thereby enhancing the user experience.

[0045] In this embodiment, by providing a reinforcing rib 114 to improve the structural strength of the lens barrel 111, the buffer cavity 1131 can isolate the path of the lens barrel 111 from the stress. During this process, a very small portion of the stress may be transmitted through the reinforcing rib 114 to the groove wall near the lens 112. Then, by adjusting the strength of the reinforcing rib 114, the buffering effect of the buffer structure 13 can be adjusted. For example, the thickness of the reinforcing rib 114 can be reduced or thickened during the processing and production of the lens barrel 111 to adjust the strength of the reinforcing rib 114. Such a design can improve the flexibility of the buffer structure 13 in absorbing the stress transmitted from the lens base 12 to at least one lens 112, thereby facilitating a balanced consideration of the imaging quality and reliability of the camera, and further enhancing the user experience.

[0046] Combine Figure 3 and Figure 5 In one embodiment, a first thread 1134 is provided on the outer surface of the first barrel section 113, and a second thread 121 that is compatible with the first thread 1134 is provided on the lens base 12. The first thread 1134 and the second thread 121 are screwed together to achieve the connection and fixation between the first barrel section 113 and the lens base 12. Such a design, on the one hand, simplifies the connection between the first barrel section 113 and the lens base 12, facilitates the production and processing of the lens module 1, and can also effectively improve the assembly convenience. On the other hand, the connection between the first barrel section 113 and the lens base 12 via the first thread 1134 can also improve the stability of the connection between the lens barrel 111 and the lens base 12, and prevent the relative movement between the lens barrel 111 and the lens base 12 due to external factors from affecting the imaging of the camera, thereby not only further improving the reliability of the camera, but also helping to improve the imaging quality of the camera.

[0047] Combine Figure 3 The axial length of the buffer cavity 1131 can be greater than the axial length of the area where the first thread 1134 is located, or the axial length of the buffer cavity 1131 can be equal to the axial length of the area where the first thread 1134 is located. This configuration can further improve the comprehensiveness of the buffer cavity 1131 in isolating stress, thereby further reducing the sensitivity of the lens body 11 and improving the imaging quality of the camera.

[0048] In one embodiment, the lens body 11 includes a lens barrel 111 and a plurality of lenses 112 disposed within the lens barrel 111. A buffer structure 13 is interposed between the lens barrel 111 and the lens base 12 to absorb stress transmitted from the lens base 12 to at least one of the lenses 112. For example, when the lens barrel 111 is connected to the lens base 12, the buffer structure 13 is first attached to the outer surface of the lens barrel 111 or the lens base 12, and then the lens barrel 111 and the lens base 12 are connected, so that the buffer structure 13 is interposed between the lens barrel 111 and the lens base 12.

[0049] Such a design, on the one hand, simplifies the installation of the buffer structure 13, facilitates the assembly of the camera module, and thus improves the assembly efficiency of the camera module. On the other hand, it can effectively improve the absorption of the stress transmitted from the lens base 12 to the lens barrel 111, isolates the force path of the lens barrel 111, and prevents the stress transmitted from the lens base 12 to the lens barrel 111 from being further transmitted to the individual lenses 112, thereby reducing the sensitivity of the lens body 11, that is, preventing the structural stability of multiple lenses 112 from changing due to the local force on the lens module 1, improving the stability of the installation position of each lens 112, and thus improving the accuracy of the lens body 11, further improving the imaging quality of the camera.

[0050] In this embodiment, the buffer structure 13 is a structural member that can play a buffering role, for example, it can be a structural member made of materials such as foam, silicone, etc. In this way, while being able to isolate the force path of the lens barrel 111 to reduce the sensitivity of the lens body 11, the buffer structure 13 can also play a shock-absorbing role, reducing the damage to the lens body 11 when it is subjected to impact forces such as falling, thereby helping to further improve the reliability of the camera. The buffer structure 13 can also be, for example, a sleeve structure that is sleeved on the outside of the lens barrel 111. The buffering effect is achieved by forming a gap between the sleeve structure and the outer surface of the lens barrel 111. The lens barrel 111 is connected and fixed to the lens base 12 through the sleeve structure. As long as the buffer structure 13 sandwiched between the lens barrel 111 and the lens base 12 can play a buffering role, there is no specific limitation in this embodiment.

[0051] In one embodiment, the buffer structure 13 includes an elastic material structural member. The elastic material structural member can be, for example, a structural member made of foam, silicone, or the like. With this arrangement, while isolating the force path of the lens barrel 111 to reduce the sensitivity of the lens body 11, the buffer structure 13 can also provide a shock-absorbing effect, reducing damage to the lens body 11 when subjected to impact forces such as falls, thereby further improving the reliability of the camera. Furthermore, by using an elastic material structural member as the buffer structure 13, when the lens barrel 111 is connected to the lens base 12, the deformation of the buffer structure 13 itself not only facilitates the secure connection between the lens barrel 111 and the lens base 12, but also effectively improves the stability of the connection between the lens barrel 111 and the lens base 12, thereby further improving the reliability of the camera.

[0052] Combine Figure 1 and Figure 5 In one embodiment, multiple connecting structures 122 are provided on the lens base 12 along its circumference, for example, three or four. The connecting structures 122 are used to connect to external components. For example, the external component may be a camera body, with the connecting structures 122 connecting the lens module 1 to the camera body, thereby completing the assembly of the entire camera. Alternatively, the external component may be an electronic device equipped with a camera module, such as a mobile phone, with the connecting structures 122 used to assemble the lens module 1 to the electronic device.

[0053] This arrangement, on the one hand, improves the comprehensiveness of the force applied to lens mount 12, thereby effectively enhancing the stability of the connection between lens module 1 and external components, and thus improving the reliability of the camera. On the other hand, providing connecting structure 122 on lens mount 12 not only facilitates connection with external components, thereby improving assembly efficiency, but also prevents the structural stability of lens 112, which would otherwise be affected by the connection structure 122 being located on lens barrel 111, thereby further improving the camera's imaging quality.

[0054] In this embodiment, the connection structure 122 is used to connect the lens base 12 to an external component. For example, the connection structure 122 is a raised plate provided on the lens base 12, with screw holes provided on the raised plate, thereby enabling the lens module 1 to be locked to the external device via screws. The connection structure 122 can also be a raised platform provided on the lens base 12, and adhesive is applied to the raised platform to achieve adhesion between the lens module 1 and the lens base 12. This is not specifically limited.

[0055] Combine Figure 3In one embodiment, the lens barrel 111 further includes a second barrel section connected to the first barrel section 113. The lens module 1 further includes a decorative member 115. The decorative member 115 is disposed on the outer circumference of the end of the second barrel section facing away from the first barrel section 113. For example, the second barrel section and the decorative member 115 can be threadedly connected via threads. This arrangement not only improves the aesthetics of the camera module, but also enhances the sealing performance of the lens module 1 through the decorative member 115, making the lens module 1 waterproof and dustproof, thereby further improving the reliability of the camera.

[0056] An exemplary embodiment of the present application provides a camera. The camera may be, for example, a traditional camera, a digital camera, a digital video camera, or a camera module equipped on an electronic device such as a tablet computer or a mobile phone.

[0057] The camera includes the lens module 1 as described above. Figure 1 As shown, the lens module 1 includes a lens body 11 and a lens holder 12. Figure 3 A buffer structure 13 is provided between the lens body 11 and the lens mount 12 to absorb stress transmitted from the lens mount 12 to the lens body 11. This design effectively reduces the stress within the lens body 11 when the lens module 1 is installed, preventing local stress on the lens body 11 from causing changes in the structural stability of the lens 112, and improving the precision of the lens body 11, thereby effectively improving the imaging effect and quality of the camera.
