[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0034] The following is for reference. Figures 1-5 This application describes a lens structure and optical device according to embodiments thereof.
[0035] Please see Figure 1 The lens structure includes: a lens housing 100 and a lens cap 200, the lens cap 200 being detachably mounted on the lens housing 100;
[0036] The lens housing 100 has a lens hole 130, and the lens is installed inside the lens housing 100. The lens is positioned directly opposite the lens hole 130. The lens housing 100 is used to provide protection and support for the lens and to ensure that the lens can be stably fixed inside during use. The lens hole 130 allows the lens to take pictures or images through the lens hole 130.
[0037] The lens housing 100 and lens cap 200 of this application can be made of hard plastic. By taking advantage of the relatively light weight of hard plastic, the overall weight of the device can be reduced, so that the lens structure is not too bulky and is easy to carry.
[0038] Please see Figure 2 and Figure 3The lens housing 100 has at least one first magnetic attractor 120 on its side wall 110. The first magnetic attractor 120 may be magnetic or a material that can attract magnetic materials. Specifically, the first magnetic attractor 120 may be a magnet, such as a magnetic sheet; the first magnetic attractor 120 may also be iron, cobalt, nickel and their alloys, such as a steel sheet, and this embodiment is not limited thereto.
[0039] Specifically, the lens housing 100 has two oppositely arranged sidewalls 110, and each of the two sidewalls 110 is provided with a first magnetic member 120. The sidewalls 110 of the lens housing 100 are magnetically connected to the lens cap 200 through the first magnetic member 120.
[0040] The first magnetic member 120 can be disposed on the inner surface of the side wall 110 of the lens housing 100. When the first magnetic member 120 is magnetically connected to the lens cap 200, the side wall 110 is sandwiched between the first magnetic member 120 and the lens cap 200. Alternatively, the first magnetic member 120 can be disposed on the outer surface of the side wall 110 of the lens housing 100, and the lens cap 200 can be directly magnetically attached to the first magnetic member 120.
[0041] It should be noted that, compared to the first magnetic component 120 being disposed on the outer surface of the side wall 110, the first magnetic component 120 being disposed on the inner surface of the side wall 110 does not directly contact the lens cap 200 magnetically, and is therefore less likely to be pulled off by the lens cap 200 during use, making it more reliable. However, at the same time, the magnetic attraction effect is slightly weaker.
[0042] To enhance the magnetic attraction effect, the first magnetic element 120 can be a magnet, and a second magnetic element 220 is provided on the inner side of the lens cover 200. The lens cover 200 is adapted to be attracted to the outer surface of the side wall 110 by the second magnetic element 220 and corresponds to the position of the first magnetic element 120.
[0043] Furthermore, the inner surface of the sidewall 110 is provided with a mounting groove 111, the first magnetic member 120 is disposed in the mounting groove 111, and the side of the first magnetic member 120 facing away from the mounting groove 111 smoothly transitions with the inner surface of the sidewall 110.
[0044] The recessed area of the mounting groove 111 significantly reduces the thickness of the side wall 110 (the area sandwiched between the first magnetic member 120 and the lens cap 200). This thinning design of the side wall 110 shortens the physical distance between the corresponding magnetic attraction of the first magnetic member 120 and the lens cap 200, making the magnetic field penetration path shorter and significantly enhancing the adsorption stability.
[0045] The lens structure may be used in the following two scenarios.
[0046] Scenario 1: If the lens is not used for a long time, cover the lens housing 100 with the lens cap 200.
[0047] For example, when not shooting for an extended period of time, the lens cap 200 can be fitted into the lens hole 130 of the lens housing 100 to completely seal the lens hole 130, thereby effectively protecting the lens from potential damage such as external dust and scratches (not shown).
[0048] Scenario 2: Using the lens for shooting or not needing to cover the lens cap for a short period of time.
[0049] For example, when the lens cap 200 is not used temporarily during shooting, or when preparing for the next shooting in a short time and not needing to cover the lens with the lens cap 200, the second magnetic attachment 220 of the lens cap 200 is aligned with the first magnetic attachment 120 on the lens housing 100. Through the action of magnetic attraction, the lens cap 200 can be firmly fixed to the lens housing 100 (see [link]). Figure 4 and Figure 5 ).
[0050] In actual use, a lanyard 210 is attached to the lens cap 200 and is connected to the lens housing 100 through the lanyard 210 to prevent the lens cap 200 from falling off the lens housing 100 and being lost; the lanyard 210 can be made of elastic cord, nylon braided cord, etc.
[0051] In the above embodiments of this application, the lens cap 200 is connected to the lens housing 100 by a lanyard 210, which can prevent the lens cap 200 from being lost. The second magnetic member 220 corresponds to the first magnetic member 120 on the lens housing 100. Through the action of magnetic attraction, the lens cap 200 can be firmly fixed on the lens housing 100, which avoids the lens cap 200 swinging during use and interfering with the user's use.
[0052] It should be noted that if the lens housing 100 and lens cap 200 are made of hard plastic, and the first magnetic component 120 is a steel sheet, the surface friction between them during magnetic contact will be relatively low. Furthermore, both components have a certain wall thickness, which will significantly weaken the magnetic force of the second magnetic component 220. In practice, the first magnetic component 120 is a magnet, particularly a strong magnet (such as a neodymium iron boron magnet), to effectively increase the magnetic force and overcome the effects of low friction and wall thickness caused by the hard plastic material.
[0053] Please see Figure 3 In some embodiments, there are two first magnetic accommodating elements 120, and the two first magnetic accommodating elements 120 are respectively disposed on the inner surfaces of the two side walls 110 of the lens housing 100.
[0054] In use, if the magnetic polarity of the second magnetic member 220 attached to one side of the lens housing 100 is the same as the outward magnetic polarity of the first magnetic member 120 at that location, the lens cap 200 will not be able to adhere to the lens housing 100. To ensure that the lens cap 200 can effectively adhere to the lens housing 100 and to avoid the problem of adhesion failure due to the same polarity between the second magnetic member 220 and the first magnetic member 120, both the inner and outer sides of the second magnetic member 220 include a first magnetic pole 221 and a second magnetic pole 222 with opposite polarity. In this way, when the lens cap 200 is close to the lens housing 100, the polarities between the second magnetic member 220 and the first magnetic member 120 on the lens housing 100 can remain complementary, ensuring effective magnetic attraction.
[0055] Specifically, the lens cap 200 has a storage groove, and the second magnetic member 220 is a ring-shaped magnet installed in the storage groove. The first magnetic pole 221 and the second magnetic pole 222 are alternately arranged on the inner and outer sides of the second magnetic member 220. Thus, the inner and outer sides of the lens cap 200 each have two opposite magnetic polarities, allowing the lens cap 200 to adhere to the surface of the lens housing 100 regardless of whether it is attached to the inner or outer side.
[0056] In other embodiments, the outer side of the first magnetic member 120 has two opposite magnetic poles, so that the lens cap 200 can be attracted to the surface of the lens housing 100 regardless of whether it is attached to the inner or outer side of the lens housing 100 where the first magnetic member 120 is located. For actual implementation, please refer to... Figure 3 The first magnetic attractor 120 has four magnetic poles on its outer side. The polarities of two adjacent magnetic poles are opposite. The four magnetic poles are connected head to head and surround each other to form a ring-shaped sheet.
[0057] In summary, the above-described technical solutions in the embodiments of this application have at least one of the following technical effects:
[0058] 1. The lens cap of this application is connected to the lens housing by a lanyard, which can avoid the problem of losing the lens cap. The second magnetic component corresponds to the first magnetic component on the lens housing. Through the action of magnetic attraction, the lens cap can be firmly fixed to the lens housing, avoiding the problem of the lens cap swinging during use and interfering with the user's use.
[0059] 2. The inner surface of the sidewall 110 is also provided with a mounting groove 111. The first magnetic member 120 is disposed in the mounting groove 111, and the side of the first magnetic member 120 facing away from the mounting groove 111 smoothly transitions with the inner surface of the sidewall 110. The recess in the mounting groove 111 significantly reduces the thickness of the sidewall 110. This thinning design of the sidewall 110 shortens the physical distance between the first magnetic member 120 and the corresponding magnetic attraction of the lens cap 200, making the magnetic field penetration path shorter and significantly enhancing the adsorption stability.
[0060] 3. The second magnetic element 220 is a ring-shaped magnet installed in the receiving slot. The first magnetic pole 221 and the second magnetic pole 222 are alternately arranged on the inner and outer sides of the second magnetic element 220. The inner and outer sides of the lens cap 200 have two opposite magnetic polarities, and the lens cap 200 can be attracted to the surface of the lens housing 100 whether it is attached to the inner or outer side.
