[0002] The appearance part is an indispensable part of the lens assembly, and it together with other components constitutes the complete structure of the lens.

[0003] Traditional appearance parts are usually made of one piece of metal material, and the side walls of the appearance parts are relatively thick, such as Figure 1 As shown, this will affect the wireless communication unit that communicates through electromagnetic waves. For example, it will cause a significant attenuation of electromagnetic wave signals during Bluetooth communication. This is because metal materials have a good shielding effect and can reflect and absorb electromagnetic waves. In addition, the strength of electromagnetic wave signals is also affected by distance. If the distance to the receiver is relatively far, the ability of the signal to penetrate the metal material will also be greatly weakened. Therefore, wireless communication technology that communicates through electromagnetic wave signals is not suitable for acting on the inside of metal appearance parts.

[0004] In order to solve the influence of the appearance parts in the traditional lens assembly on the electromagnetic wave signal, it is necessary to improve the structure of the lens assembly. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0041] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] See also Figure 2As shown, the present application proposes a lens assembly 100, which includes an appearance member 10, a mounting frame 30 and a display screen 40. A window 110 is provided on the side wall of the appearance member 10 and penetrates the inside thereof; the mounting frame 30 is connected to the appearance member 10 adjacent to the window 110 to be mounted at the window 110, and a mounting area is formed in the middle of the mounting frame 30; the mounting frame 30 allows electromagnetic waves to pass through; and the display screen 40 is disposed in the mounting area.

[0043] It can be understood that the appearance part 10 proposed in the technical solution of the present application is made of metal material, which has good mechanical properties, stability and corrosion resistance. However, the use of metal material also makes the lens assembly 100 have a strong electromagnetic shielding effect, thereby affecting the propagation of electromagnetic waves of the internal wireless communication module.

[0044] The technical solution of the present application proposes to open a window 110 on the side wall of the appearance part 10, and to set a mounting frame 30 for electromagnetic waves to pass through at the window 110, and to install a display screen 40 in the mounting area formed in the middle of the mounting frame 30. Among them, the design of the mounting frame 30 satisfies the conditions for electromagnetic waves to pass through, and the material used for the mounting frame 30 can be a non-metallic material, such as a plastic material, so that the shielding effect of the mounting frame 30 on electromagnetic waves is small and negligible. Therefore, after the mounting frame 30 and the display screen 40 are installed to form a sealed protection for the inside of the appearance part 10, its electromagnetic waves can be transmitted through the mounting frame 30 (the frame of the mounting frame), ensuring the accuracy and stability of electromagnetic wave propagation.

[0045] In addition, when a display screen 40 is mounted on the exterior member 10 through the mounting frame 30, the display screen 40 can be used to display lens parameters in real time, such as lens focal length, lens aperture, lens depth of field, etc. This not only improves the aesthetics of the lens assembly 100, but also enhances the user experience, allowing the user to intuitively understand the current state of the lens, helping the user to better adjust the shooting and improve the shooting effect.

[0046] The shape of the installation frame 30 is adapted to the shape of the window 110 opened on the appearance member 10 . Usually, the window 110 is a rectangular window, and thus the installation frame 30 is a rectangular frame, in which the display screen 40 is installed.

[0047] See also Figure 3As shown, in some embodiments, the appearance member 10 is provided with a first positioning portion, and the mounting frame 30 is provided with a second positioning portion (not shown in the drawings); the mounting frame 30 is positioned in the window 110 through the cooperation between the first positioning portion and the second positioning portion. In this way, precise positioning between the mounting frame 30 and the appearance member 10 is achieved, ensuring that the mounting frame 30 can be accurately and stably positioned in the window 110, thereby improving the stability and reliability of the connection between the mounting frame 30 and the appearance member 10.

[0048] Furthermore, the first positioning portion is a first positioning step 120 formed on the appearance member 10 around the window 110, and the second positioning portion is a second positioning step formed on the peripheral edge of the installation frame 30; the first positioning step 120 and the second positioning step are complementary and fit.

[0049] In this embodiment, the appearance part 10 and the mounting frame 30 are positioned by steps. The first positioning step 120 provided on the appearance part 10 and the second positioning step provided on the mounting frame 30 are complementary and fit, and then through the complementary fit of the steps, the mounting frame 30 can be accurately placed in the window 110, avoiding the problem of position offset or shaking, so that the positioning of the mounting frame 30 is accurate; secondly, the step structure can increase the contact area between the mounting frame 30 and the appearance part 10, and improve the stability of the overall structure, especially under vibration or impact environment; moreover, the step-type positioning method makes the installation process simpler and more intuitive, reducing the difficulty and error rate of installation; and the step structure itself also has a certain structural strength, which can enhance the compression and tension resistance of the entire component to a certain extent.

[0050] Therefore, the use of step positioning not only improves the accuracy and stability of installation, but also speeds up the installation process and improves the overall quality of the product.

[0051] It is understandable that positioning the mounting frame 30 on the appearance member 10 by step positioning is only one of the positioning means of the present application. In some other embodiments, other positioning structures can also be used to complete the operation steps. For example, positioning cooperation between the positioning column and the positioning hole, positioning cooperation between the positioning protrusion and the positioning groove, etc.

[0052] After the installation frame 30 is positioned, the installation frame 30 can be fixed to the appearance part 10 by applying glue around the installation frame 30 for reinforcement. In this process, the size and position of the glue points need to be controlled so that they can be evenly distributed around the installation frame 30 and fully cover the contact surface between the installation frame 30 and the appearance part 10, so as to ensure that the connection between the installation frame 30 and the appearance part 10 is more firm and stable.

[0053] See also Figure 3 as well as Figure 4As shown, in some embodiments, a first locking portion is provided on the appearance member 10, and a second locking portion is provided on the mounting frame 30; the mounting frame 30 is locked in the window 110 through the cooperation between the first locking portion and the second locking portion.

[0054] In this embodiment, another reinforcement method is proposed to form a stable connection between the installation frame 30 and the appearance part 10. The relative glue fixation is achieved by the cooperation between the first locking part provided on the appearance part 10 and the second locking part provided on the installation frame 30, so that the connection of the installation frame 30 is more stable and reliable, and the loosening and falling off of the installation frame 30 can be effectively prevented. At the same time, the design of the locking part can also take into account the need for reusability. For example, a detachable locking structure is adopted, so that the installation frame 30 can be easily disassembled and reinstalled when necessary.

[0055] Therefore, the design of the locking portion improves the stability and reliability of the entire structure and ensures the long-term use effect of the mounting frame 30. At the same time, the flexible design of the locking portion also meets the needs of different application scenarios and improves the applicability and convenience of the product.

[0056] See also Figure 3 as well as Figure 4 As shown, in some embodiments, the first locking portion is a first extension block 130 extending from the appearance member 10 toward the inner side around the window 110, and a first locking hole 140 is provided on the first extension block 130; the second locking portion is a second extension block 310 extending from the mounting frame 30, and a second locking hole 320 is provided on the second extension block 310; wherein, when the mounting frame 30 is positioned in the window 110, the first locking hole 140 is aligned with the second locking hole 320.

[0057] In this embodiment, the specific design of the first locking portion and the second locking portion is further clarified. When the installation frame 30 is positioned in the window 110, the first locking hole 140 is aligned with the second locking hole 320. At this time, the installation frame 30 can be firmly locked in the window 110 by inserting a locking member (such as a screw, bolt, etc.) through the two locking holes and performing a tightening operation (such as rotating the screw head). This locking method is not only simple and easy to operate, but also has a high locking strength, and can effectively prevent the installation frame 30 from loosening or falling off.

[0058] It is worth noting that the first locking portion is extended and formed on the inner side of the appearance member 10, and the second locking portion is arranged corresponding to the first locking portion, that is, the locking area between the mounting frame 30 and the appearance member 10 is located on the inner side of the appearance member 10. In this way, after the locking is completed, the first locking portion, the second locking portion, and the locking members such as screws are all inside the appearance member 10, and no traces of locking can be revealed from the outside, thereby improving the stability of the structure while improving the neatness and aesthetics of the overall exterior of the structure.

[0059] Before installing the mounting frame 30 on the exterior member 10 , the display screen 40 needs to be installed and fixed on the mounting frame 30 in advance to prevent the display screen 40 and other components from shaking or shifting on the mounting frame 30 .

[0060] See also Figure 2 As shown, in some embodiments, the lens assembly 100 further includes a transparent cover plate 20 , which is disposed above the installation area to protect the display screen 40 .

[0061] In this embodiment, the transparent cover plate 20 can be provided to ensure that the content of the display screen 40 is clearly visible while providing protection. The transparent cover plate 20 can be a plastic transparent cover plate 20 or a glass transparent cover plate 20, for example, an acrylic plate, a polycarbonate sheet, tempered glass, and quartz glass.

[0062] In some embodiments, the transparent cover 20 is connected to the mounting frame 30 , and the anti-shielding transparent cover 20 completely covers the mounting area on the mounting frame 30 ; or, the transparent cover 20 is connected to the appearance part 10 , and the transparent cover 20 completely covers the window 110 .

[0063] In this embodiment, two specific installation methods of the transparent cover plate 20 are proposed.

[0064] One installation method is: the transparent cover plate 20 is connected to the installation frame 30, and the transparent cover plate 20 completely covers the installation area on the installation frame 30. The installation area is the installation area of ​​the display screen 40, that is, under the installation setting of this structure, the setting area of ​​the transparent cover plate 20 can be relatively small, and it is set on the basis of being able to shield the display screen 40 on the installation frame 30, and the area between the transparent cover plate 20 and the surrounding appearance part 10 is protected and shielded by the plastic frame of the installation frame 30.

[0065] Another installation method is: the transparent cover plate 20 is connected to the appearance member 10, and the transparent cover plate 20 completely covers the window 110. In this way, the transparent cover plate 20 completely covers the installation frame 30 and the display screen 40 arranged on the installation frame 30, and the installation area of ​​the transparent cover plate 20 is relatively large, and then the transparent cover plate 20 can also protect the installation frame 30, thereby increasing the protection area.

[0066] Regardless of whether the transparent cover plate 20 is connected to the mounting frame 30 or the appearance member 10 , the firmness and reliability of the connection need to be ensured.

[0067] In some embodiments, a mounting groove 330 is formed on the mounting frame 30 or the appearance part 10, and the transparent cover plate 20 is embedded in the mounting groove 330 and fixed by glue; wherein, when the transparent cover plate 20 is embedded in the mounting groove 330, the top of the transparent cover plate 20 is flush with the top of the mounting groove 330.

[0068] In this embodiment, it is proposed that when installing the transparent cover plate 20, the transparent cover plate 20 is precisely embedded in the installation groove 330 to ensure that it matches the contour of the installation groove 330. At the same time, the top of the transparent cover plate 20 is flush with the top of the installation groove 330. This design allows the transparent cover plate 20 to remain flat after installation without bulges or depressions. This not only improves the appearance, but also helps to maintain the stability and shielding effectiveness of the transparent cover plate 20.

[0069] When the transparent cover plate 20 is connected to the mounting frame 30 , the mounting frame 30 itself is flush with the peripheral appearance member 10 . In addition, the shapes of the mounting frame 30 and the transparent cover plate 20 are adapted to the outer shape of the cylindrical appearance member 10 .

[0070] The use of glue further enhances the connection strength between the transparent cover plate 20 and the mounting groove 330. The glue can fill the small gap between the transparent cover plate 20 and the mounting groove 330 to form a strong adhesive layer. In this way, even under the action of external force, the transparent cover plate 20 is not easy to fall off or shift, thereby ensuring its long-term stable shielding effect.

[0071] See also Figure 5 As shown, in some embodiments, the lens assembly 100 also includes a skeleton 50, a bayonet support 60 and a bayonet 70; the bayonet support 60 is installed on the skeleton 50; the bayonet 70 is installed at an end of the bayonet support 60 away from the skeleton 50, and the bayonet 70 is used to connect to the camera body; wherein the appearance component 10 is covered on the periphery of the skeleton 50, the bayonet support 60 and the bayonet 70, and forms a detachable connection with the bayonet support 60.

[0072] In this embodiment, the appearance part 10 is covered on the periphery of the skeleton 50, the bayonet support part 60 and the bayonet 70. When installed, a detachable connection is formed between the appearance part 10 and the bayonet support part 60, and only a connection is formed between the bayonet support part 60, thereby reducing the relevant amount of the appearance part 10 during installation. Compared with the traditional installation method of the appearance part 10, after the lens is connected to the camera body through the bayonet 70 and the lens image quality is adjusted to be qualified, the appearance part 10 can be installed without involving the disassembly step of the bayonet 70. Therefore, by transferring the installation object of the appearance part 10, the operation steps are reduced, thereby ensuring the continuous stability of the image quality.

[0073] See also Figure 6As shown, in some embodiments, the lens assembly 100 further includes a voice coil motor 80; the voice coil motor 80 is fixed to the inner side of the frame 50 by a positioning and locking structure 90; wherein the positioning and locking structure 90 is used to lock and fix the voice coil motor 80 from the bottom and the top after the voice coil motor 80 is positioned.

[0074] In this embodiment, the voice coil motor 80 can realize fast and accurate lens positioning and adjustment. Further, the voice coil motor 80 is fixed to the inner side of the frame 50 through the positioning locking structure 90. After the voice coil motor 80 is placed in the predetermined position, the positioning locking structure 90 will lock and fix the voice coil motor 80 from the bottom and top at the same time, thereby firmly supporting the voice coil motor 80 from multiple directions, thereby preventing it from moving or vibrating during operation. The stability and durability of the lens assembly 100 are ensured, providing strong support for high-quality optical imaging.

[0075] Among them, the positioning and locking structure 90 can be a positioning and locking structure including conventional positioning columns, locking holes, etc., which can be designed and assembled based on actual settings and will not be described in detail here.

[0076] The present application also provides a lens, which includes the lens assembly 100 as described above.

Furthermore, the image pickup device also adopts all the technical solutions of all the embodiments of the above lens assembly 100, and thus at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
