[0029] The focusing mechanism is an accessory of an optical instrument and plays a role in adjusting the focal length in the optical instrument. It is widely used in photography and videography, especially in scenes where precise focusing and adjustment of the light direction are required. By adjusting the focal length, the focusing effect of light can be better controlled, and the quality and effect of shooting can be improved. In the focusing mechanism of the prior art, the tightness of the focusing knob is achieved by the manufacturing tolerance and assembly accuracy of the focusing mechanism. This focusing mechanism is very inconvenient during use. Since the tightness of the focusing knob cannot be adjusted, the user cannot adjust the tightness of the focusing knob according to his own needs. The focusing knob is often adjusted during the use of the optical instrument. The focusing mechanism is prone to wear. Long-term use may cause the focusing knob to be too loose, making focusing inconvenient or even impossible to focus correctly. The fill light for adjusting the focal length usually includes components such as a face cover, a heat sink, a focusing screw and a back cover. The inner cavity of the face cover is nested with waterproof glass and a first lens from the inside to the outside, and the second lens is fixed to the middle of the inner cavity of the lampshade by a lens pressing sheet. One end of the focus screw is threadedly connected to the screw hole of the rear cover and the screw hole of the plate, and then fixed to the screw screw hole at the other end of the heat sink. The focus adjustment is achieved by rotating the focus screw. In the prior art, the focus is usually achieved by using a screw and a rotation method, which has the problems of unclear damping, difficulty in fixing when focusing, and easy sliding, which affects the user experience.

[0030] See also Figures 1 to 8 In order to solve the above problems, the embodiment of the present application provides a fill light 10 with adjustable rotation sensitivity, including a middle frame assembly 20, a sliding assembly 30, a lamp body 40 and a damping adjustment member 50. The middle frame assembly 20 is provided with a slide groove 21 in the axial direction, the sliding assembly 30 is slidably arranged in the slide groove 21, the lamp body 40 is arranged on the sliding assembly 30, and the damping adjustment member 50 includes a knob 51, a gear 52 and a damping member 53. The knob 51 is fixedly connected to the gear 52, and the knob 51 and the gear 52 are rotatably connected to the middle frame assembly 20 through the damping member 53. The sliding assembly 30 is provided with a rack 31 along the axial direction, and the gear 52 is meshed with the rack 31.

[0031] See also Figure 1 , Figure 2 , Figure 4 and Figure 5In the rotation sensitivity adjustable fill light 10 provided in the present application, the rotation sensitivity adjustable fill light 10 includes a middle frame assembly 20, a sliding assembly 30, a lamp body 40 and a damping adjustment member 50. The middle frame assembly 20 constitutes the main external structure of the rotation sensitivity adjustable fill light 10, and the lamp body 40 can be arranged in the middle frame assembly 20. In some embodiments, the middle frame assembly 20 can be made of metal material, such as aluminum alloy material. The aluminum alloy material has high strength and can withstand large external forces to ensure the stability and durability of the middle frame assembly 20. At the same time, it has good corrosion resistance and can be used for a long time in a humid or corrosive environment without being easily damaged. It is light in weight, which can ensure the stability and durability of the device and is easy to carry and use. In some embodiments, the middle frame assembly 20 is provided with a slide groove 21 in the axial direction. The slide groove 21 can be set into different shapes as needed, such as a rectangle. In some embodiments, the slide groove 21 is set to a rectangle, and the extension direction of the slide groove 21 is parallel to the extension direction of the length of the middle frame assembly 20. The sliding component 30 is slidably arranged in the slide groove 21. The sliding component 30 can slide in the slide groove 21 to make the sliding component 30 and the middle frame component 20 move relative to each other. The lamp body 40 is arranged on the sliding component 30. The lamp body 40 can move driven by the sliding component 30. The damping adjustment member 50 can increase the damping feeling of the fill light 10 with adjustable rotational sensitivity when adjusting, so that the fill light 10 with adjustable rotational sensitivity is easy to fix during adjustment, and the sliding phenomenon is reduced, thereby improving the user experience when using the fill light 10 with adjustable rotational sensitivity.

[0032] See also Figures 1 to 8The damping adjustment member 50 includes a knob 51, a gear 52 and a damping member 53. The knob 51 is fixedly connected to the gear 52. Rotating the knob 51 can cause the gear 52 to rotate. The knob 51 and the gear 52 are rotatably connected to the middle frame assembly 20 through the damping member 53. The sliding assembly 30 is axially provided with a rack 31. The gear 52 meshes with the rack 31. The working principle of the cooperation between the gear 52 and the rack 31 is to convert the rotational motion of the gear 52 into the linear motion of the rack 31. When the knob 51 is rotated, the knob 51 drives the gear 52 to rotate. The rotation of the gear 52 is converted into the linear motion of the rack 31 through the transmission mechanism of the gear 52 and the rack 31. The linear motion of the rack 31 causes the sliding assembly 30 to move linearly relative to the middle frame assembly 20, thereby realizing the focusing process of the fill light 10 with adjustable rotation sensitivity. The transmission mechanism composed of the gear 52 and the rack 31 has high transmission efficiency, can provide a large torque output, is sensitive to response, and is easy to adjust, which is conducive to improving the user experience. At the same time, the transmission mechanism of the gear 52 and the rack 31 is relatively simple in structure, which is conducive to the maintenance and care of the fill light 10 with adjustable rotation sensitivity. In some embodiments, the focusing distance of the fill light 10 with adjustable rotation sensitivity is 12-13 mm. Since the stroke of the above-mentioned focusing distance is relatively short, the modulus of the gear 52 can be set to 1.0, so that the outer diameter and tooth shape of the gear 52 are relatively small, so that the knob 51 only needs to rotate about half a circle to complete the stroke focusing process, so that the focusing of the fill light 10 with adjustable rotation sensitivity is faster and quicker. In some embodiments, the material of the gear 52 is nylon or POM (polyoxymethylene), which has better self-lubrication and wear resistance, and can improve the wear resistance of the fill light 10 with adjustable rotation sensitivity. The fill light 10 with adjustable rotation sensitivity uses a gear 52 and a rack 31 to achieve focusing, and a damping member 53 is added to the knob 51. Due to the soft friction force of the damping member 53 being clamped, the knob 51 has a good damping feeling when it is rotated. The damping member 53 can make the focusing process more stable and not too sensitive when the user rotates the knob 51 to focus. The sliding assembly 30 is provided with a rack 31 along the axial direction, and the rack 31 is arranged in the sliding assembly 30. The knob 51 and the gear 52 are connected to the middle frame assembly 20 for damping rotation. When in use, the user rotates the knob 51, and the rotation of the knob 51 drives the gear 52, and then drives the rack 31 to move. The movement of the rack 31 can drive the sliding assembly 30 to move relative to the middle frame assembly 20, so as to achieve a stable focusing process, and can make the focusing process of the lamp body 40 more stable and not too sensitive, thereby improving the user's experience. In some embodiments, the gear 52 is provided with a threaded hole 522 , and a screw 511 is fixed to the knob 51 , and the screw 511 is screwed into and glued into the threaded hole 522 .The screw 511 can be integrally injection molded with the knob 51 , and the locking gear 52 is partially fixed by the screw 511 , and glue is applied to the screw 511 to fix the screw 511 , so that the screw 511 cannot rotate inversely and loosen from the gear 52 .

[0033] See also Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the damping member 53 includes a first damping ring 531 and a second damping ring 532 located on opposite sides of the shell wall of the middle frame assembly 20, the first damping ring 531 is located on the inner side of the middle frame assembly 20, and the second damping ring 532 is located on the outer side of the middle frame assembly 20. The first damping ring 531 and the second damping ring 532 can be used to reduce mechanical vibration and impact. The first damping ring 531 and the second damping ring 532 reduce the vibration amplitude of the mechanical system by consuming vibration energy, so that the focusing process of the lamp body 40 is more stable and not too sensitive, protecting the mechanical components and extending their service life. In some embodiments, the first damping ring 531 and the second damping ring 532 can be made of rubber. The first damping ring 531 is sleeved between the knob 51 and the middle frame assembly 20. When the knob 51 is rotated, the first damping ring 531 absorbs and consumes vibration energy through elastic deformation and soft friction, so that the knob 51 has a better damping feeling when it rotates. The second damping ring 532 is sleeved between the gear 52 and the middle frame assembly 20. The first damping ring 531 and the second damping ring 532 can both be set as O-type damping rings. When the knob 51 locks the gear 52, the force of the clamping of the first damping ring 531 and the second damping ring 532 is tightened accordingly, so as to adjust the damping force and the rotation feel, so that the rotation position of the knob 51 can be stopped at will without loosening, so as to achieve a more stable and not overly sensitive focusing process of the lamp body 40. In one embodiment, after the O-ring is clamped, a gap of 0.3 mm to 0.5 mm is left between the two end surfaces of the sleeve 24 and the gear 52 and the knob 51 as an initial installation and debugging gap. The space for the O-ring to be compressed and deformed can be adjusted by rotating the screw 511, thereby achieving better damping force and rotation feel.

[0034] Continue reading Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8In some embodiments, the middle frame assembly 20 includes a middle frame 23 and a sleeve 24. The middle frame 23 can be made of metal, such as aluminum alloy. The aluminum alloy has high strength and can withstand large external forces. It also has the advantage of being light in weight, which can ensure the stability and durability of the fill light 10 with adjustable rotation sensitivity, and is easy to carry and use. The slide groove 21 is opened in the middle frame 23, and the sliding assembly 30 can move in the slide groove 21 so that the sliding assembly 30 moves relative to the middle frame 23. The sleeve 24 is fixed to the middle frame 23 by a fastener 60. In some embodiments, the fastener 60 can be a screw structure. For example, three fasteners 60 can be set to connect the sleeve 24 at the same time. The three fasteners 60 are arranged at intervals, which is conducive to improving the stability of the connection between the sleeve 24 and the middle frame 23. The sliding assembly 30 is axially slidably arranged in the middle frame 23, the knob 51 is located on the outer side of the middle frame 23, the gear 52 is located on the inner side of the middle frame 23, the knob 51 is inserted into the shaft sleeve 24, and one end of the knob 51 passing through the shaft sleeve 24 is fixedly connected to the gear 52. The knob 51 and the gear 52 are fixedly connected so that when the knob 51 is rotated, the positions of the knob 51 and the gear 52 are relatively fixed. The knob 51 and the gear 52 are rotatably connected to the shaft sleeve 24 through the damping member 53. When the knob 51 is rotated, the rotation of the knob 51 drives the gear 52, and then drives the rack 31 to move. The movement of the rack 31 can drive the sliding assembly 30 to move relative to the middle frame assembly 20, thereby realizing a stable focusing process.

[0035] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the shell wall of the middle frame assembly 20 is provided with an adjustment hole 22, and at least one of the knob 51 and the gear 52 is penetrated in the adjustment hole 22. Specifically, in some embodiments, the knob 51 is penetrated in the adjustment hole 22, and the gear 52 is not penetrated in the adjustment hole 22. In other embodiments, the knob 51 is not penetrated in the adjustment hole 22, and the gear 52 is penetrated in the adjustment hole 22. In other embodiments, the knob 51 is penetrated in the adjustment hole 22, and the gear 52 is penetrated in the adjustment hole 22. The adjustment hole 22 is provided with a step surface 221 on the edges on opposite sides, and the first damping ring 531 and the second damping ring 532 are provided on the step surface 221. The setting of the step surface 221 is conducive to the installation of the first damping ring 531 and the second damping ring 532. The first damping ring 531 and the second damping ring 532 can increase the damping feeling when adjusting the focal length. The first damping ring 531 and the second damping ring 532 are installed on the gear 52 and are arranged on the step surface 221, that is, the first damping ring 531 and the second damping ring 532 are respectively on the two end surfaces of the sleeve 24. The first damping ring 531 and the second damping ring 532 form a clamping state with the gear 52, so that the gear 52 produces a strong damping effect when rotating. Due to the soft friction force of the first damping ring 531 and the second damping ring 532 being clamped, the knob 51 has a good damping feeling when rotating.

[0036] See also Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments, a third damping gasket 533 is sandwiched between the end of the gear 52 away from the knob 51 and the sliding assembly 30. The third damping gasket 533 can be made of silicone material, which has good elasticity and fatigue resistance. A mounting groove 521 is provided at the end of the gear 52 away from the knob 51. The third damping gasket 533 is arranged in the mounting groove 521, which is conducive to improving the stability of the third damping gasket 533. In some embodiments, the third damping gasket 533 and the gear 52 are firmly fixed by glue, so that the third damping gasket 533 is not easy to loosen when the knob 51 is rotated. In some embodiments, glue may not be applied between the third damping gasket 533 and the gear 52, so that the third damping gasket 533 can rotate freely in the mounting groove 521, thereby achieving the effect of providing a damping sense by increasing the friction force.

[0037] Continue reading Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the sliding assembly 30 is provided with anti-collision gaskets 54 at both ends of the rack 31, and the side of the anti-collision gasket 54 facing away from the gear 52 is bonded to the sliding assembly 30. Specifically, adhesive backing can be provided on both sides of the anti-collision gasket 54 during installation, and the anti-collision gasket 54 can be prevented from being easily loosened by increasing the adhesive area of ​​the adhesive backing. At the same time, since the adhesive surface is in the same direction as the impact force surface of the knob 51, the anti-collision gasket 54 is not easily loosened after being fixed in position. In some embodiments, the thickness of the anti-collision gasket 54 can be set to 5 mm, which can effectively ensure that the anti-collision gasket 54 has sufficient strength and elasticity, thereby improving the wear resistance and fatigue resistance of the anti-collision gasket 54. In some embodiments, the thickness of the anti-collision gasket 54 can be set to be greater than 5 mm, so as to effectively ensure that the anti-collision gasket 54 has sufficient strength and elasticity.

[0038] See also Figure 3 and Figure 4In some embodiments, one of the middle frame assembly 20 and the sliding assembly 30 is provided with a first guide column 61 and a second guide column 62 arranged in the axial direction, and the other is provided with a first guide groove 63 and a second guide groove 64 opened in the axial direction. Specifically, in one embodiment, the middle frame assembly 20 is provided with a first guide column 61 and a second guide column 62 arranged in the axial direction, and the sliding assembly 30 is provided with a first guide groove 63 and a second guide groove 64 opened in the axial direction.

The first guide column 61 is slidably connected in the first guide groove 63, and the second guide column 62 is slidably connected in the second guide groove 64, and the sliding clearance between the first guide column 61 and the first guide groove 63 is greater than the sliding clearance between the second guide column 62 and the second guide groove 64. For example, two first guide columns 61 and two second guide columns 62 are used, and four guide columns are used for guiding. The two first guide columns 61 can accurately position and guide, and the two second guide columns 62 are roughly positioned, so that the first guide columns 61 and the second guide columns 62 will not get stuck during sliding, and the first guide columns 61 and the second guide columns 62 can slide smoothly.
