[0041] Please refer to Figures 1 to 5 , the present invention discloses a liquid crystal tunable electronic filter 10, which includes an adapter module 100, a polarizing lens module 200, and a graduated lens module 300 that are sequentially stacked. The polarizing lens module 200 is rotatably connected to the adapter module 100, and the graduated lens module 300 is fixedly connected to the adapter module 100.

[0042] Embodiment 1

[0043] In the present invention, the liquid crystal adjustable electronic filter 10 is an ND type product, and the transmittance of the entire surface changes uniformly with the change of voltage; the voltage across the liquid crystal display lens is adjusted by a voltage control component to change the movement direction of liquid crystal ions, achieving different degrees of light reduction effects. For example, when the movement direction of liquid crystal ions is perpendicular to the polarizer (polarizing film), the light transmittance is close to 0%; through the adjustment of the voltage control component, the resistance value of the circuit connected is changed, so that the voltage across the liquid crystal display lens is changed, prompting the angle between the movement direction of liquid crystal ions and the polarizer (polarizing film) to change within the range of 0 to 90°, thereby realizing the automatic adjustment of the transmittance of the liquid crystal display lens;

[0044] Embodiment 2

[0045] In the present invention, the liquid crystal adjustable electronic filter 10 is a GND type product, and the transmittance of the entire surface is controlled by different voltages to achieve a gradual change in transmittance; different voltages are applied to each liquid crystal basic unit, and the arrangement direction of liquid crystals is controlled by different voltages, so that the transmittance of the lens changes differently, thereby realizing the GND filter function and achieving the purpose of light reduction and light adjustment in some areas during photographing.

[0046] As Figure 6 shown, the adapter module 100 includes: an adapter ring body 110, a plurality of movable clips 120, a diameter adjustment rotating disk 130, and a radial force switching rotating disk 140. The plurality of movable clips 120 are arranged in a circular array on the adapter ring body 110. The diameter adjustment rotating disk 130 drives each movable clip 120 to move radially along the adapter ring body 110. The radial force switching rotating disk 140 is used to provide a radial force for each movable clip 120, and the direction of this radial force can be switched based on the rotation adjustment of the radial force switching rotating disk 140.

[0047] As Figure 8 shown, the polarizing filter module 200 includes: a polarizing filter frame 210, a polarizing filter lens 220, and a polarizing filter retaining ring 230. The polarizing filter lens 220 is fastened to the polarizing filter frame 210 through the polarizing filter retaining ring 230. In this embodiment, a polarizing filter adjustment handle 211 is provided on the polarizing filter frame 210 (as Figure 8 shown), and by setting the polarizing filter adjustment handle 211, it is convenient to perform rotational adjustment on the polarizing filter frame 210.

[0048] As Figure 9 shown, the graduated filter module 300 includes: a graduated filter frame 310, a graduated filter 320, and a cover plate 330. The graduated filter 320 is fastened to the graduated filter frame 310 through the cover plate 330.

[0049] Next, the specific structure of the above-mentioned adapter module 100 will be described:

[0050] Each movable clip 120 is provided with a radial guiding block 121 (as Figure 7 shown), and the adapter ring body 110 is provided with a plurality of radial guiding grooves 111 arranged in an annular array and corresponding to each radial guiding block 121 (as Figure 6 shown); in this embodiment, the movable clip 120 is provided with a radially inward pressing engaging tooth 122 facing the center and a radially outward pushing engaging tooth 123 facing away from the center (as Figure 7 shown), and by providing the radially inward pressing engaging tooth 122 and the radially outward pushing engaging tooth 123, it is convenient to form a stable clamping with the inner wall or the outer wall of the photographic equipment lens.

[0051] As Figure 10 shown, the radial force switching turntable 140 is provided with a plurality of accommodating grooves 141 arranged in an annular array, and each accommodating groove 141 is provided with a radially inward pressing elastic piece 150 and a radially outward pushing elastic piece 160. The radially inward pressing elastic piece 150 is used to provide a centripetal force pointing to the center point for the radial guiding block 121, and the radially outward pushing elastic piece 160 is used to provide a centrifugal force away from the center point for the radial guiding block 121; based on the rotation adjustment of the radial force switching turntable 140, the radial guiding block 121 is alternatively connected to the radially inward pressing elastic piece 150 or the radially outward pushing elastic piece 160;

[0052] As Figure 10 shown, the radially inward pressing elastic piece 150 is bent to form a radially inward pressing guiding portion 151 and a radially inward pressing clamping portion 152, and the radially outward pushing elastic piece 160 is bent to form a radially outward pushing guiding portion 161 and a radially outward pushing clamping portion 162.

[0053] Furthermore, each movable clip 120 is provided with a radial driving block 122 (as Figure 6 shown), and the aperture adjustment rotating disk 130 is provided with a plurality of radial driving grooves 131 arranged in an annular array and corresponding to each radial driving block 122 (as Figure 6 shown); when the aperture adjustment rotating disk 130 rotates forward or backward, through the cooperation of the radial driving grooves 131 and the radial driving blocks 122, the movable clip 120 is driven to move radially. In this embodiment, the aperture adjustment rotating disk 130 is provided with an aperture adjustment handle 132 (as Figure 6 shown), and by providing the aperture adjustment handle 132, it is convenient to perform rotational adjustment on the aperture adjustment rotating disk 130.

[0054] Next, the specific structure of the above-mentioned graduated filter module 300 will be described:

[0055] As Figure 9 shown, the graduated filter 320 includes two mutually adhered glass frames 321, and a plurality of independent chambers 322 are formed inside the two glass frames 321, and each independent chamber 322 is filled with liquid crystal;

[0056] As Figure 9 shown, the variable-focus lens module 300 further includes a variable-focus lens electronic control device 340 for providing different voltages to the liquid crystals in each independent chamber 322.

[0057] Furthermore, the variable-focus lens module 300 further includes a remote controller 350 for remotely controlling the variable-focus lens electronic control device 340 (as Figure 1 shown), and the variable-focus lens electronic control device 340 can be remotely controlled through the remote controller 350.

[0058] Next, the working principle of the above liquid crystal adjustable electronic filter 10 will be described:

[0059] As Figure 11 shown, according to the actual situation, the radial force switching turntable 140 in the adapter module 100 is switched in radial force, or the radially inward pressing elastic piece 150 is brought into contact with the radial guiding block 121 to provide a centripetal force pointing to the center point, or the radially outward pushing elastic piece 160 is brought into contact with the radial guiding block 121 to provide a centrifugal force away from the center point, so that the filter can be clamped on the outer wall or inner wall of the lens of different types of photographic equipment;

[0060] As Figure 11 shown, the radial force switching turntable 140 is rotated to bring the radially inward pressing elastic piece 150 into contact with the radial guiding block 121. During the rotation of the radial force switching turntable 140, the radial guiding block 121 slides along the radially inward pressing guiding portion 151 of the radially inward pressing elastic piece 150 and enters the radially inward pressing clamping portion 152. Thus, the radial guiding block 121 can be stably clamped on the radially inward pressing clamping portion 152 of the radially inward pressing elastic piece 150. At this time, the radially inward pressing elastic piece 150 generates an elastic force to provide a centripetal force pointing to the center point for the radial guiding block 121. It should be noted that the radial guiding block 121 abuts against the radially outward pushing guiding portion 161 of the radially outward pushing elastic piece 160 at the same time, and the radially outward pushing guiding portion 161 and the radially inward pressing clamping portion 152 elastically clamp the radial guiding block 121, and the radial guiding block 121 is stably clamped and not prone to shaking;

[0061] Immediately afterwards, the aperture adjustment rotating disk 130 is rotated. Through the cooperation of the radial driving groove 131 and the radial driving block 122, the aperture adjustment rotating disk 130 drives the movable clamping pieces 120 to expand radially outward (the radial guiding block 121 slides radially along the radial guiding groove 111). Thus, the aperture surrounded by the plurality of movable clamping pieces 120 is appropriately enlarged. It should be noted that since the movable clamping pieces 120 expand radially outward, the radial guiding block 121 will push the radially inward pressing elastic piece 150 to adaptively deform and generate an elastic force;

[0062] Next, insert a number of movable clamping pieces 120 with a larger aperture into the lens of the photographic equipment. Release the aperture adjustment rotary disk 130. The centripetal elastic force generated by radially pressing the elastic piece 150 inward will push the radially guiding block 121 to reset, so that the radially guiding block 121 can clamp the outer wall of the lens of the photographic equipment.

[0063] Similarly, if it is necessary to clamp the inner wall of the lens of the photographic equipment by the radially guiding block 121 (first take out the entire filter from the lens), rotate the radial force switching rotary disk 140 in the reverse direction. The radially guiding block 121 slides along the radially outward pushing guiding portion 161 of the radially outward pushing elastic piece 160 (and at the same time exits from the radially inward pressing clamping portion 152 of the original radially inward pressing elastic piece 150). Then the radially guiding block 121 will enter the radially outward pushing clamping portion 162 of the radially outward pushing elastic piece 160, thus completing the radial force switching adjustment. Then, rotate the aperture adjustment rotary disk 130 to appropriately reduce the aperture formed by a number of movable clamping pieces 120. Insert the number of movable clamping pieces 120 with a smaller aperture into the lens of the photographic equipment. Release the aperture adjustment rotary disk 130. The centrifugal elastic force generated by the radially outward pushing elastic piece 160 will push the radially guiding block 121 to reset, so that the radially guiding block 121 can clamp the inner wall of the lens of the photographic equipment.

[0064] The radial force switching rotary disk 140 of the present invention has the following technical advantages (please refer to Figure 11 ):

[0065] 1. Only a simple forward or reverse rotation of the radial force switching rotary disk 140 is required to quickly switch the direction of the radial force, and the switching can be completed very efficiently.

[0066] 2. The radially inward pressing elastic piece 150 and the radially outward pushing elastic piece 160 are provided. The cooperation of the two elastic pieces not only generates opposite elastic forces, but also the two elastic pieces will clamp the radially guiding block 121. On the one hand, it enables the radially guiding block 121 to smoothly switch between the two elastic pieces. On the other hand, it enables the radially guiding block 121 to be stably clamped by the two elastic pieces for positioning.

[0067] 3. When one end of the radial guide block 121 is pressed against the radial inward pressure holding portion 152 of the radial inward pressure elastic sheet 150, the other end of the radial guide block 121 is also pressed against the radial outward pushing guide portion 161 of the radial outward pushing elastic sheet 160. The radial outward pushing guide portion 161 of the radial outward pushing elastic sheet 160 will give the radial guide block 121 an oblique blocking force to prevent the radial guide block 121 from easily detaching from the radial inward pressure holding portion 152 of the radial inward pressure elastic sheet 150. A certain external force needs to be applied to rotate the radial force switching rotary disk 140, thereby improving the stability of the radial guide block 121. In the process of the radial inward pressure holding portion 152 of 50 moving to the radial outward pushing holding portion 162 of the radial outward pushing elastic sheet 160, the radial guide block 121 will slide along the radial outward pushing guide portion 161 of the radial outward pushing elastic sheet 160, and the radial outward pushing guide portion 161 of the radial outward pushing elastic sheet 160 guides the movement of the radial guide block 121, which is beneficial for the radial guide block 121 to be accurately positioned; it can be seen that the radial outward pushing guide portion 161 can not only improve the stability of the radial guide block 121, but also help the radial guide block 121 to be accurately moved into position; similarly, the function of the radial inward pressure guide portion 151 is the same as that of the radial outward pushing guide portion 161.

[0068] like Figure 1 and Figure 2 As shown, the present invention also discloses an optical lens, comprising the above-mentioned liquid crystal adjustable electronic filter 10, and also comprising a lens body 20, on which the liquid crystal adjustable electronic filter 10 is mounted. According to actual conditions, the adapter module 100 can be clamped on the inner wall or outer wall of the lens body 20. The radial force switching dial 140 adjusts the direction of the radial force by rotating, so that the movable clamp 120 is clamped on the outer wall of the lens body 20 in the form of centripetal force, or the movable clamp 120 is clamped on the inner wall of the lens body 20 in the form of centrifugal force.

[0069] like Figure 1 and Figure 2 As shown, the present invention further discloses a photographic device, including the above-mentioned optical lens and a camera body 30 , on which the optical lens 20 is mounted.

[0070] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
