Description

Technical Field

[0001] This utility model relates to the field of photographic accessories technology, and in particular to an external lens and shooting device. Background Technology

[0002] With the rapid advancements in mobile phone technology, the quality, parameters, and shooting modes of built-in cameras have improved significantly. Consumers' demands for mobile phone photography have also increased with these hardware upgrades. This continuous pursuit and improvement of mobile phone photography capabilities has led to the development of external lenses. Early external lenses were typically telephoto lenses, designed to address the limitations of traditional mobile phones when shooting distant or panoramic scenes, which were often restricted by the phone's overall structure. Some smartphones, aiming for even higher shooting requirements, incorporate a dedicated camera module lens attached to the original camera module, thus enhancing image quality. However, this method of attaching an external camera module lens to the smartphone casing requires time for alignment and fixation, resulting in inefficient connection and installation. Utility Model Content

[0003] The present invention provides an external lens and shooting device to solve the technical problem of low connection and installation efficiency when aligning and fixing smartphones with camera module lenses.

[0004] First aspect

[0005] This utility model discloses an external lens, comprising:

[0006] A lens assembly having an axial direction and a circumferential direction around the axial direction, the lens assembly having a mounting end on one side along the axial direction, the mounting end having a plurality of positioning blocks spaced apart along the circumferential direction;

[0007] A frame, adapted to a camera assembly of an electronic device, has a first end and a second end disposed opposite to each other along the axial direction. The first end is provided with a mounting groove for limiting the mounting end to be installed. The inner sidewall of the mounting groove is provided with a plurality of limiting blocks spaced apart along the circumferential direction. A notch is formed between two adjacent limiting blocks to allow the positioning block to enter and exit.

[0008] The end face of one of the mounting end and the first end is provided with glass beads, and the end face of the other end is provided with glass bead groove. When the positioning block enters the mounting groove through the notch and rotates in the mounting groove until the positioning block and the notch are offset by a preset angle, the glass beads are aligned and embedded in the glass bead groove.

[0009] In one embodiment, there are multiple glass bead grooves, which are arranged at intervals along the circumference. When the positioning block and the notch are offset at two different preset angles, the glass beads are embedded in two different glass bead grooves.

[0010] In one embodiment, there are multiple mounting slots spaced apart, and one glass bead is located on the end face of the first end; the glass bead slot extends radially outward around the circumferential central axis of the lens assembly to form a sliding groove, and when the mounting end is aligned and installed in different mounting slots, the glass bead is limited to different length positions of the sliding groove.

[0011] In one embodiment, there are multiple mounting slots spaced apart, and one glass bead is located on the end face of the first end. The glass bead is equidistant from the central axis of each mounting slot. The straight-line distance between the glass bead slot and the central axis of the lens assembly is equal to the straight-line distance between the glass bead and the central axis of the mounting slot.

[0012] In one embodiment, the external lens includes an elastic pad disposed between the first end and the mounting end. The elastic pad accumulates and releases elastic force along the axial direction. When the positioning block is offset from the notch by a preset angle, the elastic force released by the elastic pad can enhance the contact force between the positioning block and the limiting block.

[0013] In one embodiment, the end face of the first end is provided with a receiving groove, and the elastic pad is partially embedded in the receiving groove; there are multiple elastic pads and the receiving grooves are one-to-one, and the elastic pads are circumferentially distributed around the opening of the mounting groove on the end face of the first end.

[0014] In one embodiment, the limiting block extends radially inward along the mounting groove and is connected to the first end, the side surface of the limiting block facing the mounting end is smoothly connected to the end face of the first end, and the elastic pad is disposed on the side of the limiting block facing the mounting end.

[0015] In one embodiment, the end face of the mounting end protrudes along the axial direction and is provided with a mounting post. The end of the mounting post extends radially outward to form the positioning block. Along the axial direction, the positioning block and the end face of the mounting end are spaced apart to form an annular clamping groove. When the positioning block rotates in the mounting groove, the limiting block is clamped in the annular clamping groove.

[0016] In one embodiment, the frame includes a blocking block that protrudes from the side of the limiting block facing away from the lens assembly. The positioning block is rotatable within the mounting groove until it abuts against the blocking block, thereby stabilizing the positioning block and the notch by rotating to a maximum preset angle.

[0017] Second aspect

[0018] The utility model discloses a shooting device, comprising:

[0019] Electronic device with a protruding camera component on the back;

[0020] As described in any of the preceding embodiments, the second end is adapted to be installed on the camera assembly, and the lens of the camera assembly is opposite to the mounting slot.

[0021] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0022] This utility model provides an external lens and a shooting device. The second end of the lens frame is adapted to the camera assembly of the shooting device. After the positioning block on the lens assembly aligns with the notch in the lens frame, it enters the mounting groove. The positioning block rotates to stably install the lens assembly on the first end of the lens frame, thereby fixing the external lens to the camera assembly of the shooting device. On the one hand, users can optimize the shooting parameters of the camera assembly of the shooting device through the function of the external lens; on the other hand, the positioning of the glass bead and the glass bead groove further improves the installation stability of the external lens on the shooting device, making the external lens and the camera assembly stably connected. Therefore, the external lens of this application has the advantages of simple structure, quick installation, optimized shooting parameters, and better shooting effect. Attached Figure Description

[0036] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Reference Figure 1 and Figure 2 This utility model provides an external lens 10, which can be combined with various lenses or lens groups to achieve different shooting functions, including but not limited to pixel count, aperture, ISO, and exposure compensation. The external lens 10 is used to mount on the camera assembly 21 protruding from the back of an electronic device 20 to form a shooting device 1 with better shooting effects. That is, the external lens 10 can serve as an auxiliary lens to optimize the shooting effect of the electronic device 20 with its built-in shooting function. The electronic device 20 includes, but is not limited to, mobile phones, tablets, educational devices, and smartwatches. Alternatively, the external lens 10 can also be mounted independently on the shooting device 1 for video and photography.

[0040] Reference Figure 2-5 This utility model provides an external lens 10, which can be used with various lenses or lens groups to achieve different shooting parameters and effects. The external lens 10 includes a lens assembly 100 and a lens frame 200 for adaptation and connection. The lens assembly 100 has an axial direction and a circumferential direction around the axial direction. The lens assembly 100 has a mounting end 110 on one side along the axial direction, and the mounting end 110 is provided with a plurality of circumferentially spaced positioning blocks 120. The lens frame 200 has a first end 210 and a second end 220 opposite each other along the axial direction. The first end 210 is provided with a mounting groove 230 for limiting the mounting of the mounting end 110. The inner sidewall of the mounting groove 230 is provided with a plurality of circumferentially spaced limiting blocks 240, and a notch 250 is formed between two adjacent limiting blocks 240 to allow the positioning blocks 120 to enter and exit the mounting groove 230. Figure 2 This illustrates that the second end 220 is adapted to install and connect to the camera assembly 21 of the electronic device 20. The lens of the camera assembly 21 is opposite to the mounting slot 230, so that the lens assembly 100 and the camera assembly 21 are aligned axially. Here, the lens assembly 100 and the lens frame 200 can also be adapted and installed separately on the electronic device 20. When the lens frame 200 is installed separately on the electronic device 20, it can be used as a decorative accessory.

[0041] Reference Figure 5-7After the positioning block 120 passes through the notch 250, it can extend inward and rotate circumferentially in the mounting groove 230, that is, the mounting end 110 rotates relative to the first end 210, and the positioning block 120 switches between the release position and the locking position. Figure 4 This illustrates that when the positioning block 120 is in the released position, the positioning block 120 is aligned with the notch 250 so that the mounting end 110 can be axially disengaged from the mounting groove 230, and the lens assembly 100 separates from the lens frame 200. Figure 5 This illustrates that when the positioning block 120 is in the locked state, the positioning block 120 and the notch 250 are offset circumferentially at a certain angle, and the positioning block 120 and the limiting block 240 are relatively limited axially to prevent the mounting end 110 from disengaging from the mounting groove 230 axially, thus fixing the lens assembly 100 and the lens frame 200 relatively. Here, the limiting block 240 is an arc-shaped block to accommodate the circumferential rotation of the positioning block 120. Of course, in this application, the shape of the limiting block 240 is not limited.

[0042] Furthermore, in conjunction with references Figure 4 and Figure 5 The end face of the mounting end 110 and the first end 210 is provided with glass beads 260, and the end face of the other end is provided with glass bead groove 130. When the positioning block 120 enters the mounting groove 230 through the notch 250 and rotates in the mounting groove 230 until the positioning block 120 and the notch 250 are offset by a preset angle, the positioning block 120 and the limiting block 240 are relatively limited along the axial direction, and the glass beads 260 are simultaneously embedded in the glass bead groove 130. Here, the glass bead 260 elastically moves in and out of the glass bead groove 130 with a distinct concave-convex feel. The cooperation between the glass bead 260 and the glass bead groove 130 enhances the rotational feel between the mounting end 110 and the first end 210. On the other hand, it serves as a reminder that when the glass bead 260 is confined within the glass bead groove 130, it indicates to the user that the preset angle has been reached, and the lens assembly 100 and the lens frame 200 are stably connected at this preset angle. Finally, when the user's rotational force is not large, the glass bead 260 and the glass bead groove 130 also serve a positioning function.

[0043] This invention provides an external lens 10 and a shooting device 1. The second end 220 of the lens frame 200 is adapted to be installed on the camera assembly 21 of the electronic device 20. The positioning block 120 on the lens assembly 100 aligns with the notch 250 of the lens frame 200 and enters the mounting groove 230. The positioning block 120 extends inward and rotates circumferentially in the mounting groove 230 to stably install the lens assembly 100 on the first end 210 of the lens frame 200, thereby fixing the external lens 10 to the camera assembly 21 of the electronic device 20. On the one hand, the user can optimize the shooting parameters of the camera assembly 21 of the shooting device 1 through the lens function of the external lens 10; on the other hand, the positioning of the glass bead 260 and the glass bead groove 130 can further improve the installation stability of the external lens 10 on the electronic device 20. Therefore, the external lens 10 of this application has the advantages of simple structure, quick installation, optimized shooting parameters, and better shooting effect.

[0044] Preferably, in one embodiment, in conjunction with reference to Figure 4 and Figure 5 The number of glass bead grooves 130 is multiple, and the multiple glass bead grooves 130 are arranged circumferentially at intervals. During the rotation of the mounting end 110 relative to the first end 210, the glass beads 260 can move and jump within adjacent glass bead grooves 130 to increase the rotation feel of the mounting end 110. When the positioning block 120 and the notch 250 are offset at two different preset angles, the glass beads 260 are embedded in two different glass bead grooves 130 to satisfy the positioning function of multiple preset angles. It should be noted that, without considering the rotation feel and the need for positioning function at multiple preset angles, the number of glass bead grooves 130 is not limited in this application.

[0045] Preferably, in conjunction with reference Figure 4 and Figure 5In one embodiment, there are multiple mounting slots 230 spaced apart, and one glass bead 260 is located on the end face of the first end 210. A glass bead groove 130 extends radially outward around the central axis of the lens assembly 100 to form a sliding groove 131. When the mounting end 110 is aligned and installed in different mounting slots 230, the glass bead 260 is positioned at different lengths within the sliding groove 131. The straight-line distances from the glass bead 260 to the central axis of different mounting slots 230 are not equal, thus limiting the glass bead 260 to different lengths within the sliding groove 131. The glass bead groove 130 is designed as a sliding groove 131 to accommodate the fit between one glass bead groove 130 and one glass bead 260, allowing the mounting end 110 to be installed in mounting slots 230 at different positions. It should be noted that, firstly, in this application, the number of mounting slots 230 is not limited; multiple mounting slots 230 are used to increase the external interface of the lens frame 200. Secondly, in this application, the shape of the glass bead groove 130 is not limited. For example, in one embodiment, when the glass beads 260 are equidistant from the central axis of each mounting slot 230, the glass bead slot 130 can be a hole-shaped point, and the distance of the glass bead slot 130 from the central axis of the lens assembly 100 is equal to the distance of the glass beads 260 from the central axis of the mounting slot 230.

[0046] Preferably, in conjunction with reference Figure 4 and Figure 8 In one embodiment, the external lens 10 includes an elastic pad 300 disposed between the mounting end 110 and the first end 210. The elastic pad 300 accumulates and releases elastic force axially. When the positioning block 120 and the notch 250 are offset by a preset angle and the positioning block 120 and the limiting block 240 are axially limited relative to each other, the elastic force released by the elastic pad 300 can further enhance the contact force between the positioning block 120 and the limiting block 240, thereby further enhancing the assembly compactness and installation stability between the mounting end 110 and the first end 210. It should be noted that, without considering the assembly compactness and installation stability between the mounting end 110 and the first end 210, the presence or absence of the elastic pad 300 is not limited in this application. In other embodiments, the positioning block 120 and the limiting block 240 can also be enhanced by interference fit.

[0047] Preferably, refer to Figure 8In one embodiment, the end face of the first end 210 is provided with a receiving groove 211. A portion of the elastic pad 300 is embedded in the receiving groove 211, and the remaining portion of the elastic pad 300 protrudes from the end face of the first end 210 to elastically abut against the end face of the mounting end 110. The receiving groove 211 increases the structural compactness of the external lens 10 and the assembly compactness of the elastic pad 300. There are multiple elastic pads 300 and receiving grooves 211, and they correspond one-to-one. The elastic pads 300 are circumferentially distributed around the opening of the mounting groove 230 on the end face of the first end 210. It should be noted that, firstly, in this application, the presence or absence of the receiving groove 211 is not limited. For example, in other embodiments, the elastic pad 300 can be directly bonded to the end face of the first end 210 to improve the installation stability between the mounting end 110 and the first end 210. Secondly, the number of elastic pads 300 and receiving grooves 211 is not limited; the circumferential distribution is to provide circumferential force balance and enhance installation stability. For example, in other embodiments, the number of elastic pads 300 can be one and arranged in a ring around the opening of the mounting groove 230, which also provides circumferential force balance.

[0048] Preferably, refer to Figure 8 In one embodiment, the limiting block 240 extends radially inward along the mounting groove 230 and is connected to the first end 210. The surface of the limiting block 240 facing the mounting end 110 smoothly contacts the end face of the first end 210, and the elastic pad 300 is disposed on the side of the limiting block 240 facing the mounting end 110. This arrangement of the limiting block 240 serves both a limiting function and provides installation space for the elastic pad 300, greatly improving the overall structural compactness of the external lens 10. Moreover, the elastic force of the elastic pad 300 directly acts on the limiting block 240, further increasing the contact force between the limiting block 240 and the positioning block 120. It should be noted that, without considering the structural compactness of the external lens 10, the placement of the elastic pad 300 is not limited in this application, as long as it is located between the mounting end 110 and the first end 210.

[0049] Preferably, in conjunction with reference Figure 5 and Figure 8In one embodiment, the end face of the mounting end 110 protrudes axially with a mounting post 140. The end of the mounting post 140 extends radially outward to form the aforementioned positioning block 120. Along the axial direction, the positioning block 120 and the end face of the mounting end 110 form an annular clamping groove 150 at a distance from each other. When the positioning block rotates within the mounting groove 230, the limiting block 240 is clamped within the annular clamping groove 150, and the positioning block 120 is hooked onto the side of the limiting block 240 opposite to the first end 210. It should be noted that in this application, the presence or absence of the mounting post 140 and the annular clamping groove 150 is not limited; any means of axially limiting the positioning block 120 and the limiting block 240 should be included. For example, in other embodiments, the positioning block 120 can be in the form of a hook to hook onto the limiting block 240, thereby achieving axially relative limiting between the two.

[0050] Preferably, in conjunction with reference Figure 5-7 The frame 200 includes a blocking block 270, which protrudes from the limiting block 240 on the side facing away from the lens assembly 100. The positioning block 120 can rotate within the mounting groove 230 until it circumferentially abuts against the blocking block 270, preventing the positioning block 120 from over-rotating after being misaligned from the notch 250, thereby stabilizing the maximum preset angle of misalignment between the positioning block 120 and the notch 250. It should be noted that, as long as the user does not apply excessive force during rotation, and without considering whether the positioning block 120 rotates excessively, the presence or absence of the blocking block 270 is not limited in this application.

[0051] Preferably, refer to Figure 5 In one embodiment, the mounting end 110 is provided with an external thread 160 on its circumferential outer side. The external thread 160 is used for the lens assembly to be individually threaded and externally assembled on some photographic equipment. It should be noted that the external thread 160 expands the external connection methods of the lens assembly 100. In this application, the presence or absence of the external thread 160 is not limited, and the mounting end 110 includes, but is not limited to, threaded external connection.

[0052] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
