It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0043] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0044] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0045] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0047] like Figures 1 to 13 As shown, according to a first aspect of this application, an eyepiece protection structure is provided, comprising: a front housing 1, a cover plate 2, a bendable spring 3, an eyepiece assembly 4, and a rear housing 5; the front housing 1 has a through hole 101; the cover plate 2 is slidably engaged with the front housing 1; the bendable spring 3 has a bending portion 301 and a support portion 302, the bending portion 301 being hinged to the cover plate 2; one end of the eyepiece assembly 4 is fixedly connected to the support portion 302; in a first bent state of the bendable spring 3, the support portion 302 is away from the front housing 1, and the cover plate 2 blocks the through hole 101; in a second bent state of the bendable spring 3, the support portion 302 is close to the front housing 1, the bending portion 301 drives the cover plate 2 to slide to remove the blocking of the through hole 101, and the other end of the eyepiece assembly 4 protrudes from the through hole 101; the rear housing 5 is connected to the front housing 1 to hold the bendable spring 3 between the front housing 1 and the rear housing 5.

[0048] Specifically, the eyepiece protection structure provided in this application mainly targets the eyepiece assembly 4 in electronic devices. An eyepiece is typically a visual optical device used to observe the image formed by a forward optical system; therefore, protection of the eyepiece assembly 4 is particularly important in electronic devices. (Refer to...) Figure 14 .

[0049] In this application, the provided eyepiece protection structure includes a cover plate 2 and a bendable spring 3 hinged to the cover plate 2. The cover plate 2 is slidable along the front housing 1, so that when the bendable spring 3 transitions from a second bent state to a first bent state, it blocks the through hole 101 on the front housing 1 through sliding movement, thereby protecting the eyepiece assembly 4. The bendable spring 3 has a first bent state (see reference). Figure 5 and Figure 6 ) and second bending state (reference) Figure 7 and Figure 8 This design allows the support portion 302 to be positioned either away from or close to the front housing 1, enabling the eyepiece assembly 4, fixed to the support portion 302, to be positioned either covered by the cover plate 2 or protruding through the through hole 101 on the front housing 1. This provides protection for the eyepiece assembly 4 or allows it to function normally. This structural design prevents external dust or forces from adversely affecting the eyepiece assembly 4 when it is not in use, while ensuring normal operation when in use, thus improving the safety performance of the eyepiece assembly 4 and extending its service life.

[0050] In the above embodiment, the bending portion 301 of the bendable spring 3 is hinged to the cover plate 2, allowing the bendable spring 3 to flexibly change between the first bending state and the second bending state, avoiding excessive limitation by the cover plate 2. (Refer to...) Figure 6 , Figure 8 and Figure 9 The hinge can be used to directly connect the cover plate 2 and the flexible spring 3 using a hole and shaft, or it can be connected using a hinge-like connector. The specific design can be tailored to actual needs, and this application does not impose any limitations on this. Furthermore, in the above structure, the position of the support portion 302 of the flexible spring 3, whether it is far from or close to the front housing 1, refers to the relative position of the flexible spring 3 in the first bent state and the second bent state. That is, when the flexible spring 3 is in the first bent state, its support portion 302 is closer to the front housing 1 than when it is in the second bent state.

[0051] Further, refer to Figure 3The connection between the front housing 1 and the rear housing 5 allows the bendable spring 3 to be located within the space formed between the front housing 1 and the rear housing 5, providing a certain degree of protection for the bendable spring 3. In addition, when the bendable spring 3 is located between the front housing 1 and the rear housing 5, and when the bendable spring 3 is in the first bent state, it can also ensure that the entire eyepiece assembly 4 is located between the front housing 1 and the rear housing 5, providing complete protection for the eyepiece, preventing it from being contacted by external dust and other debris, and improving its protective effect.

[0052] In the above structure, reference Figures 2 to 3 The specific structures of the cover plate 2 and the bendable spring 3 can be configured according to actual needs. For example, in one embodiment, two cover plates 2 are provided, and the bendable spring 3 is designed with a symmetrical structure, meaning that both sides of the bendable spring 3 have bending portions 301, which are respectively connected to the two cover plates 2. In practical applications, when an external force is applied to the middle support portion 302 of the bendable spring 3, the bending portions 301 on both sides can easily change their bending state, allowing the bendable spring 3 to switch between the first bending state and the second bending state, so that the two cover plates 2 connected to the bending portions 301 on both sides can separate or close each other, thereby protecting the eyepiece assembly 4 or allowing it to protrude through the front housing 1 for operation. (Refer to...) Figures 5 to 8 as well as Figure 13 The structure in this embodiment is simple, easy to operate, and suitable for mass production.

[0053] Optionally, such as Figures 5 to 9 As shown, the cover plate 2 includes a plate portion 201 and a first fork portion 202. The bent portion 301 is provided with a ring 303. The ring 303 is inserted into the first fork portion 202. The first shaft 6 passes through the first fork portion 202 and the ring 303, thereby realizing the hinge connection between the bent portion 301 and the cover plate 2.

[0054] Specifically, in this embodiment, the cover plate 2 has a plate portion 201 for blocking the through hole 101 and a first fork portion 202 for connecting with the bending portion 301 of the bendable spring piece 3. The ring 303 on the bending portion 301, through its cooperation with the first fork portion 202, allows the first shaft 6 to pass through both the first fork portion 202 and the ring 303 simultaneously, thus achieving the purpose of hinged connection between the bending portion 301 and the cover plate 2. The first fork portion 202 and the ring 303 are integral structures on the cover plate 2 and the bendable spring piece 3, respectively. After being hinged by the first shaft 6, the connection reliability between the cover plate 2 and the bendable spring piece 3 can be improved.

[0055] Optionally, such as Figure 6 and Figure 8 As shown, the diameter of the ring 303 is larger than the diameter of the first shaft 6.

[0056] Specifically, in this embodiment, the diameter of the ring 303 is larger than the diameter of the first shaft 6. This allows for a certain deformation allowance at the hinge position during the bending deformation process of the bendable spring 3 as it transitions between the first and second bending states. This prevents the hinge structure (first shaft 6, ring 303, or first fork 202) from being damaged by external forces, further improving the reliability of the hinge. Furthermore, the larger diameter of the ring 303 provides a certain deformation allowance at the hinge position, making it easier and less strenuous for the bendable spring 3 to transition between the first and second bending states, thus improving its operational convenience.

[0057] Optionally, such as Figure 6 and Figure 8 As shown, the front housing 1 includes a positioning post 102, which passes through the bending part 301. After the rear housing 5 is connected to the front housing 1, there is a gap L between the end face of the positioning post 102 and the rear housing 5.

[0058] Specifically, in this embodiment, the front housing 1 and the rear housing 5 are fixedly connected, and the positioning post 102 on the front housing 1 provides the assembly position for fixing the bendable spring 3. A certain gap L is left between the end face of the positioning post 102 and the rear housing 5, so that when the bendable spring is bent and deformed, it can move towards the rear housing 5, avoiding wear between it and the positioning post 102 or the rear housing 5, thus protecting the above-mentioned installation structure of the bendable spring 3.

[0059] Optionally, such as Figure 3 and Figure 4 As shown, a spring 10 is also fitted on the positioning post 102, and at least a portion of the spring 10 is located within the gap L.

[0060] Specifically, based on the above embodiment, a spring 10 is provided, which is sleeved on the positioning post 102 and pressed on the bending part 301. This allows the bendable spring 3 to maintain a stable connection with the front housing 1 when it is bent and deformed (i.e. when switching between the first bending state and the second bending state), while also allowing the bendable spring 3 to have a certain displacement space. This prevents it from falling off the positioning post 102 during deformation, further improving the reliability of its connection.

[0061] Optionally, such as Figures 5 to 11 As shown, the eyepiece protection structure also includes a reset button 7, which puts the bendable spring 3 into a second bent state.

[0062] Specifically, in this embodiment, the reset button 7 enables the bendable spring 3 to be in a second bent state, that is, the reset button 7 enables the eyepiece assembly 4 to be in a working position, so that the eyepiece can be used to observe the imaging of the optical system when needed. The reset button 7 can be implemented through a mechanical structure, that is, the reset button 7 is directly connected to the bendable spring 3 through a mechanical structure. Pressing the reset button 7 with external force can drive the mechanical structure to bend and deform the bendable spring 3, so that the bendable spring 3 changes from the first bent state to the second bent state under the action of external force, thus fulfilling the working requirements of the eyepiece assembly 4. In addition, the function of the reset button 7 can also be implemented through electronic control, that is, the reset button 7 is connected to the control circuit of the electronic device on which the eyepiece assembly 4 is used, so that the bendable spring 3 can change from the first bent state to the second bent state through electronic control. The specific implementation method can be designed according to actual needs, and this application does not limit it.

[0063] Optionally, such as Figure 10 As shown, the reset button 7 is mounted on the front housing 1 and extends out from the front housing 1.

[0064] Specifically, in this embodiment, the reset button 7 is located on the front housing 1 and extends from the front housing 1, so that in practical applications, the user can directly control the bending deformation of the bendable spring 3 by pressing the reset button 7, which improves the convenience of operation.

[0065] Optionally, such as Figure 9 and Figure 10 As shown, the support portion 302 of the bendable spring 3 extends into a reset portion 304. The reset portion 304 is hinged to the reset button 7. The movement of the reset button 7 drives the reset portion 304 to move, thereby causing the reset portion 304 to move the support portion 302 closer to the front housing 1, and the bendable spring 3 moves from the first bending state to the second bending state.

[0066] Specifically, in this embodiment, the reset button 7 is hinged to the reset part 304 of the bendable spring 3, so that when the reset button 7 moves (e.g., is pressed), it can drive the reset part 304 to move accordingly, thereby driving the support part 302 closer to the front housing 1, realizing the state of the eyepiece assembly 4 from the blocked state to the state of extending into the through hole 101 of the front housing 1, satisfying the working position of the eyepiece assembly 4.

[0067] Optionally, such as Figure 11 and Figure 12 As shown, the reset part 304 and the reset button 7 are hinged by a connecting rod 9. The connecting rod 9 includes a first hole 901 that is hinged to the reset button 7 and a second hole 902 that is hinged to the reset part 304. The second hole 902 is an elongated hole.

[0068] Specifically, in this embodiment, the hinge between the reset part 304 and the reset key 7 is achieved through the connecting rod 9, that is, the two ends of the connecting rod 9 are respectively provided with a first hole 901 and a second hole 902.

[0069] Optionally, such as Figure 9 and Figure 11 As shown, the reset part 304 has a second fork, through which the second shaft 8 passes, and through the second fork and the second hole 902, thereby achieving a hinge connection between the connecting rod 9 and the reset part 304. The second hole 902 is designed as an elongated hole, which allows for better tolerance matching between the connecting rod 9, the reset part 304, and the reset key 7 during assembly, thus improving assembly convenience.

[0070] According to the second aspect of this application, such as Figure 14 As shown, an electronic device is provided, including an eyepiece protection structure of the first aspect.

[0071] Specifically, in this embodiment, the provided electronic device includes the eyepiece protection structure provided in any of the above embodiments, which protects the eyepiece assembly 4, giving the eyepiece assembly 4 a longer service life, thereby improving the service life of the electronic device. The electronic device can be any type of optical imaging device with the eyepiece assembly 4, such as a VR device or an AR device; this application does not limit its application to this type.

[0072] Optionally, such as Figure 14 As shown, the electronic device also includes a headband 11, a main body 12 connected to the headband 11, and an eyepiece protection structure mounted on the main body 12.

[0073] Specifically, in this embodiment, the electronic device has a main body and a headband 11 connected to the main body. An eyepiece protection structure can be housed within the main body. The headband 11 can be used to secure the main body 12 to the user's head, improving ease of use. Since the eyepiece protection structure can provide some protection to the eyepiece assembly 4 when it is not in use, the user can observe a clearer image when using the eyepiece assembly 4, improving the user experience of the electronic device. Furthermore, in electronic devices, two sets of eyepiece assemblies 4 are typically provided to meet the observation needs of the user's left and right eyes. Therefore, two eyepiece protection structures can be provided within the main body 12 according to actual needs, such as... Figure 14 As shown.

[0074] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0075] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
