[0002] With the change of lifestyle, people gradually like to use mobile phones and other shooting devices to record the scenery around them. Under this demand, people have higher and higher requirements on the maximum viewing range that the shooting equipment can shoot. Since the camera of the shooting equipment usually only faces one direction, the shooting equipment cannot obtain 360-degree panoramic photos. Based on this, people usually use a panoramic lens device to be installed at the lens position of the shooting equipment. However, the traditional panoramic lens device has two lenses on opposite sides and captures the image into the lens of the shooting equipment through a reflecting prism. However, the lens of the traditional panoramic lens device must be kept at the same horizontal plane as the lens of the shooting equipment so that the image captured by the panoramic lens device can be captured by the lens of the shooting equipment.

In the process from the edge of the first convex surface 3111 to the center of the first convex surface 3111, the first convex surface 3111 gradually extends in the lighting direction of the first lens 311 in a direction away from the second lens 312, so that the first convex surface 3111 protrudes from the lighting front end along the lighting direction of the first lens 311. 210, with the first convex surface 3111 as the center of the sphere, the first convex surface 3111 can receive light within a range of at least 180 degrees from top to bottom of the lighting front end 210, and light within a range of at least 180 degrees from left to right of the lighting front end 210, so that the first lens 311 can receive light within a range of at least 180 degrees, and the front lens 310 can capture scenes within a range of at least 180 degrees. It should be noted that, according to different shooting requirements, the front lens 310 also includes multiple lenses, and the multiple lenses are respectively fixed between the first lens 311 and the second lens 312. The incident light of the first lens 311 passes through the multiple lenses and the second lens 312 respectively, and is refracted to the first reflector 330 to meet different usage requirements.

[0034] refer to Figure 3The rear lens 320 includes a third lens 321 and a fourth lens 322 which are sequentially arranged along the lighting direction. The fourth lens 322 is located on a side close to the first reflector 330, and the third lens 321 is located on a side away from the first reflector 330. The third lens 321 is fixed to the lighting rear end 220. A second convex surface 3211 is provided on the side of the third lens 321 facing away from the fourth lens 322. The second convex surface 3211 is a spherical arc surface. In the process from the edge of the second convex surface 3211 to the center of the second convex surface 3211, the second convex surface 3211 gradually extends along the lighting direction of the third lens 321 to the side away from the fourth lens 322, so that the second convex surface 3211 protrudes from the lighting along the lighting direction of the third lens 321. The rear end 220 takes the second convex surface 3211 as the center of the sphere. The second convex surface 3211 can receive light within a range of at least 180 degrees from top to bottom of the lighting rear end 220, and light within a range of at least 180 degrees from left to right of the lighting rear end 220, so that the third lens 321 can receive light within a range of 180 degrees, and the rear lens 320 can capture scenes within a range of at least 180 degrees. It should be noted that the rear lens 320 also includes multiple lenses, and the multiple lenses are respectively fixed between the third lens 321 and the fourth lens 322. The incident light of the third lens 321 passes through the multiple lenses and the fourth lens 322 respectively, and is refracted to the first reflector 330. Multiple lenses are arranged to meet different shooting requirements.

[0035] refer to Figure 4The first reflector 330 includes a first reflective surface 331 and a second reflective surface 332. The first reflector 330 is in the shape of a triangular prism. The first reflective surface 331 and the second reflective surface 332 are respectively located on both sides of the triangular prism. The first reflective surface 331 and the front lens 310 are arranged to be inclined relative to each other. The angle between the first reflective surface 331 and the incident light of the front lens 310 is 45 degrees. The first reflective surface 331 reflects the incident light of the front lens 310 to the second reflector 340, and the light passes through the first reflective surface The angle between the direction reflected by the first reflective surface 331 and the first reflective surface 331 is 45 degrees, so that the light is reflected to the second reflective mirror 340 along the arrangement direction of the first reflector 330 and the second reflector 340; the second reflective surface 332 is relatively inclined to the rear lens 320, and the angle between the second reflective surface 332 and the incident light of the rear lens 320 is 45 degrees. The second reflective surface 332 reflects the incident light of the rear lens 320 to the second reflective mirror 340, and the incident light is reflected by the second reflective surface 332. The angle between the direction of the first reflector 330 and the second reflector 340 is 45 degrees, so that the light is reflected to the second reflector 340 along the arrangement direction of the first reflector 330 and the second reflector 340; the second reflector 340 is provided with a third reflective surface 341, and the third reflective surface 341 is relatively inclined to the lens of the shooting device 40. The angle between the third reflective surface 341 and the lighting direction of the lens of the shooting device 40 is 45 degrees, and the angle between the reflected light of the first reflector 330 and the third reflective surface 341 is also 45 degrees. When shooting, the light from the front lens 310 and the light from the rear lens 320 are respectively reflected by the first reflecting mirror 330 to the third reflecting surface 341, and the third reflecting surface 341 reflects the light from the front lens 310 and the light from the rear lens 320 along the lighting direction of the lens of the shooting device 40 to the lens of the shooting device 40, so that the lens of the shooting device 40 takes a photo containing two semi-panoramic pictures, and the two semi-panoramic pictures are combined into a panoramic picture through the photo retouching program of the shooting device 40.

[0036] refer to Figure 2 The mounting frame 100 includes a back panel 110 and a side panel 120 extending from the edge of the back panel 110. The side panel 120 and the back panel 110 form a mounting cavity 130. The mounting cavity 130 is used to mount the shooting device 40. An opening 131 is provided at one end of the mounting cavity 130. Part of the structure of the shooting device 40 can slide into the mounting cavity 130 through the opening 131, so that the shooting device 40 is fixedly connected to the mounting frame 100. It can be understood that the mounting frame 100 can also be fixedly connected to the shooting device 40 in other ways, such as being clamped on the shooting device 40 by a clamping block, or being fixedly connected to the shooting device 40 by magnetic attraction.

[0037] refer to Figure 2 and Figure 3The lens barrel 200 includes a lighting tube 230 and a reflecting frame 240. The lighting tube 230 is overlapped on the side of the mounting frame 100 facing away from the opening 131, so that the shooting device 40 will not be blocked by the lighting tube 230 when sliding into the mounting cavity 130. The lighting tube 230 has a lighting front end 210 and a lighting rear end 220 that are higher than the mounting frame 100, so that the front lens 310 and the rear lens 320 are respectively higher than the mounting frame 100 and the shooting device 40, so that the front lens 310 and the rear lens 320 are not blocked by the shooting device 40 during lighting shooting. The reflecting frame 240 is located between the lighting front end 210 and the lighting rear end 220. One end of the reflecting frame 240 is fixedly connected to the lighting tube 230, and the other end of the reflecting frame 240 is connected to the side of the back plate 110 facing away from the mounting cavity 130. The first reflecting mirror 330 and the second reflecting mirror 340 are fixedly installed on the reflecting frame 240.

[0038] The light tube 230 is provided with a connection opening 231 between the light front end 210 and the light rear end 220. The end of the reflector frame 240 is embedded in the light tube 230 through the connection opening 231, so that the reflector frame 240 is fixedly connected to the light tube 230. The light tube 230 and the reflector frame 240 are also fixed by screws to increase the stability between the light tube 230 and the reflector frame 240. The end portion of the reflector frame 240 embedded in the light tube 230 is provided with a fixing groove 241. The edge of the mirror surface on the first reflector 330 fits with the bottom wall of the fixing groove 241 so that the first reflector 330 will not deviate relative to the reflector frame 240, and the airtightness between the first reflector 330 and the reflector frame 240 is increased. In this embodiment, The edge of the first reflecting surface 331 and the edge of the second reflecting surface 332 are respectively attached to the bottom wall of the fixing groove 241, and the bottom wall of the fixing groove 241 is also provided with an avoidance groove 2411, which can avoid the connection between the first reflecting surface 331 and the second reflecting surface 332 to prevent the tip of the connection from touching the bottom wall of the fixing groove 241 and causing damage to the first reflector 330. It should be noted that the light tube 230 and the reflection frame 240 can also be connected in one piece, for example, the light tube 230 and the reflection frame 240 are cast as one piece, and the reflection frame 240 extends along a direction perpendicular to the axis of the light tube 230 and is connected to the mounting frame 100, that is, the reflection frame 240 and the light tube 230 are an integrally formed T-shaped structure.

[0039] The reflector frame 240 is provided with a first channel 242 and a second channel 243 which are interconnected. The axis of the first channel 242 is parallel to the arrangement direction of the first reflector 330 and the second reflector 340, and the first reflector 330 and the second reflector 340 are respectively located at two ends of the first channel 242. The axis of the second channel 243 is parallel to the lighting direction of the lens of the shooting device 40, and the lens of the shooting device 40 and the second reflector 340 are respectively located at two ends of the second channel 243. The reflected light of the first reflector 330 is reflected to the second reflector 340 through the first channel 242, and the reflected light of the second reflector 340 is reflected to the lens of the shooting device 40 through the second channel 243.

[0040] The lens group 300 also includes a conductive lens 350, which is located on the axis of the second channel 243. One side of the conductive lens 350 is opposite to the lens of the shooting device 40, and the other side of the conductive lens 350 receives the light of the front lens 310 and the light of the rear lens 320 of the second reflector 340 respectively. Since the light of the front lens 310 is reflected to the third reflective surface 341 via the first reflective surface 331, and the light of the rear lens 320 is reflected to the third reflective surface 341 via the second reflective surface 332, and the third reflective surface 341 is inclined, the reflection point of the light of the front lens 310 on the third reflective surface 341 and the reflection point of the light of the rear lens 320 on the third reflective surface 341 are not on the same horizontal plane. The side of the conductive lens 350 close to the second reflector 340 is a convex lens, so that the conductive lens 350 can converge the light from the third reflective surface 341 to the optical axis of the conductive lens 350, thereby reducing the shooting deviation of the lens of the shooting device 40.

[0041] refer to Figure 5 The reflector frame 240 is fixed to the side of the back plate 110 facing away from the installation cavity 130. The mounting frame 100 also includes a screw 140. The screw 140 passes through the back plate 110 from the side of the back plate 110 close to the installation cavity 130 and is threadedly connected and fixed to the reflector frame 240, so that the mounting frame 100 and the reflector frame 240 are detachably connected, thereby facilitating the replacement of mounting frames 100 of different sizes to meet the use of different models of shooting equipment 40. It can be understood that the reflector frame 240 and the mounting frame 100 can also be connected in other ways, such as using a snap-fit ​​method to achieve a detachable connection.

[0042] One end of the side panel 120 away from the back panel 110 is enclosed to form a display window 150, and the display window 150 is used for the screen display of the shooting device 40. The display window 150 is connected to the installation cavity 130. The shape of the installation cavity 130 corresponds to the shape of the shooting device 40. When the shooting device 40 enters the installation cavity 130 through the opening 131, the side panel 120 fits with the side of the shooting device 40, and the back panel 110 fits with the back of the shooting device 40, so that part of the structure of the shooting device 40 is just stuck in the installation cavity 130. It can be understood that the shooting device 40 can also be completely accommodated in the installation cavity 130 as a whole. At this time, the structure enclosed by the back panel 110 and the side panel 120 is similar to the protective shell structure.

[0043] The back plate 110 is also provided with an avoidance hole 111, which is opened at the position of the lens of the shooting device 40. The avoidance hole 111 is used to avoid the lens of the shooting device 40. The avoidance hole 111 can avoid the lens of the shooting device 40. When the shooting device 40 is installed in the installation cavity 130, the lens of the shooting device 40 is aligned with the reflection frame 240 through the avoidance hole 111. The back plate 110 is also provided with a notch groove 112. The depth direction of the notch groove 112 is the same as the thickness direction of the back plate 110, and the length direction of the notch groove 112 is the same as the direction in which the shooting device 40 slides into the installation cavity 130. The two ends of the notch groove 112 in the length direction are respectively connected to the opening 131 and the avoidance hole 111. In the process of the shooting device 40 sliding into the installation cavity 130 through the opening 131, the lens of the shooting device 40 can slide along the notch groove 112, and the notch groove 112 avoids the lens of the shooting device 40, thereby avoiding wear of the lens of the shooting device 40.

[0044] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
