[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on September 4, 2023, with application number 202311138901.2 and application name "A Kind of Smart Glasses", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of mechanical technology, and in particular to smart glasses. Background Art

[0004] Smart glasses, as a new type of intelligent wearable device, combine the latest information technology (IT) with the functions of traditional glasses. They have become increasingly popular due to their advantages such as portability, ease of use, and rich functions.

[0005] Typically, when wearing smart glasses, the temples need to be placed at the level of the ears, creating a clamping force on the head. To ensure a better fit between the temples and the head, as shown in Figure 1a, existing smart glasses typically incorporate spring hinges at the junction of the temples and the frame. This clamping force is provided by the compression or extension of the spring in the spring hinges. However, the temples of existing smart glasses do not fit the user's head well. Users with smaller heads may experience instability while those with larger heads may experience head pinching and discomfort, making them unsuitable for users with varying head widths.

[0006] In summary, the structural design of smart glasses still needs further research.

[0007] Summary of the Invention

[0008] The present application provides smart glasses for providing a substantially constant clamping force to suit users with different head widths.

[0009] The present application provides a pair of smart glasses, comprising a frame and temples, wherein the temples comprise a temple body and a coil spring adjustment portion, wherein the coil spring adjustment portion comprises a coil spring, wherein a first end of the coil spring is connected to the frame, and a second end of the coil spring is connected to the temple body.

[0010] In the above design, the frame and the temple body are connected by a coil spring. The elastic characteristics of the coil spring can be utilized to set the working area of ​​the coil spring when the temple body expands outward within the deformation range where the elastic force approaches a constant. The basically constant elastic force generated by the deformation of the coil spring can be utilized to provide a basically constant clamping force relative to the head, so that the smart glasses can be suitable for users with different head widths.

[0011] In one possible design, a clamping force that can simultaneously meet wearing comfort and wearing stability can be pre-tested. Then, referring to the elastic force characteristic curve of the coil spring, the working area of ​​the coil spring when the temple body expands outward (called the first working area) is set within the deformation range corresponding to the clamping force, for example, within a small deformation range just after the rapid rising period, so that the elastic force provided by the coil spring during the expansion of the temple body can remain basically constant, and at the same time, the elastic force can meet the user's requirements for wearing comfort and wearing stability.

[0012] It should be noted that the present application does not limit the working area (referred to as the second working area) of the coil spring during the non-expansion process of the temple body (including the folded state of the temple body, and any state between the folded state and the open state). For example, in some schemes, the second working area of ​​the coil spring can be maintained as a point, that is, the coil spring maintains a fixed deformation amount during the non-expansion process. Alternatively, in other schemes, the second working area of ​​the coil spring can also be a certain deformation area during the rapid rise period. In this case, the elastic force provided by the coil spring during the non-expansion process is different from the elastic force provided during the expansion process. Alternatively, the second working area of ​​the coil spring can also be the area between the rapid rise period and the first working area. In this case, the elastic force provided by the coil spring during the non-expansion process is basically the same as the elastic force provided during the expansion process.

[0013] For example, this application provides the following three possible smart glasses structures.

[0014] Structure 1

[0015] In structure 1, the coil spring adjustment portion may further include a support portion connected between the second end of the coil spring and the temple body.

[0016] With this design, the support portion can connect the second end of the coil spring to the outside of the frame, so as to achieve connection with the temple body outside the frame.

[0017] In a possible design, the spectacles frame includes a frame body, and the first end of the coil spring is fixed in the frame body.

[0018] With this design, the first end of the coil spring is configured as a fixed end, and the displacement of the second end of the coil spring relative to the first end can drive the temple body connected to the second end to rotate relative to the frame.

[0019] In a further possible design, a fixed shaft is provided in the frame, a first slot is defined on the fixed shaft, and the first end of the coil spring is embedded in the first slot.

[0020] With this design, the first end of the coil spring can be caught by the first slot, thereby being fixed in the frame. This fixing method is easy to prepare and does not require the introduction of additional fixing parts, which helps to reduce costs and structural complexity.

[0021] In a further possible design, the support portion has a hollow accommodating cavity, in which the coil spring and the fixed shaft are embedded. This prevents dust and other impurities from entering the cavity and corroding the coil spring, thereby affecting the performance of the coil spring.

[0022] In a further possible design, the housing of the accommodating chamber has a first opening, and the second end of the coil spring is bent and embedded in the first opening. In this way, the second end of the coil spring can be engaged with the housing of the accommodating chamber, thereby achieving a fixed connection between the second end of the coil spring and the support portion.

[0023] In one possible design, the coil spring adjustment portion may further include a folding adjustment portion, which is connected between the support portion and the temple body and is used to fold or unfold the temple body relative to the support portion to achieve a folded state or an unfolded state of the smart glasses.

[0024] In a further possible design, the frame includes a limiting component that limits the rotational range of the support portion relative to the frame to achieve the outward expansion state of the smart glasses. The limiting component can be any component or combination of components capable of achieving a limiting function, including but not limited to a limiting hole, a limiting slot, a screw limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, and the like.

[0025] In a further possible design, the limiting component is a limiting hole, the supporting part passes through the limiting hole, one end is connected to the second end of the coil spring, and the other end is connected to the folding adjustment part, so that the supporting part is restricted from rotating within the range of the limiting hole.

[0026] In a further possible design, under the action of the limiting component and the folding adjustment part, the smart glasses can be in any of the following states: when the supporting part is located at the first edge of the limiting component and the folding adjustment part is in the folded state, the smart glasses are in the folded state; when the supporting part is located at the first edge of the limiting component and the folding adjustment part is in the open state, the smart glasses are in the open state; when the supporting part is located at the second edge of the limiting component or between the first edge and the second edge, the smart glasses are in the outward expanded state.

[0027] In the above design, the smart glasses can achieve three states: folded, opened, and expanded, thanks to a coil spring disposed inside the frame and a folding adjustment portion disposed outside the frame. The folded and opened states are achieved by the folding adjustment portion, without the coil spring being involved. Therefore, the deformation of the coil spring in these two states or between these two states remains constant. The second working range of the coil spring is a point, which corresponds to the minimum deformation of the coil spring in the first working range. Conversely, the expanded state is achieved by the deformation of the coil spring. Because the elastic force of the coil spring is essentially constant throughout the first working range, the smart glasses can provide a substantially constant clamping force regardless of the expanded position. This allows the smart glasses to adapt to users of various head widths and meet users' requirements for wearing comfort and stability, resulting in high versatility.

[0028] It is understood that in other possible designs, when the smart glasses are in the open state, the support portion can also be located between the first and second edges of the retaining member, and the folding adjustment portion can be in the open state. In other words, the open state of the smart glasses is achieved by the coil spring in conjunction with the folding adjustment portion. In this case, the second working range of the coil spring is a deformation range, the starting point of which corresponds to the deformation range before the minimum deformation range in the first working range, and the end of which corresponds to the minimum deformation range in the first working range.

[0029] Structure 2

[0030] In the second structure, the coil spring adjustment portion may further include a support portion, which is connected between the frame and the first end of the coil spring and is used to support the coil spring outside the frame.

[0031] In a possible design, the frame has a first opening, the support portion passes through the first opening, the first end is fixed in the frame, and the second end is fixedly connected to the first end of the coil spring.

[0032] This design allows for a fixed connection between the first end of the coil spring and the frame. In this case, the first end of the coil spring is configured as a fixed end, and displacement of the second end of the coil spring relative to the first end drives the temple body connected to the second end to rotate relative to the frame.

[0033] In a further possible design, the second end of the support portion has a fixed shaft, a first slot is defined on the fixed shaft, and the first end of the coil spring is embedded in the first slot.

[0034] In the above design, the first end of the coil spring can be caught by the first slot, thereby being fixed in the frame. This fixing method is easy to prepare and does not require the introduction of additional fixing parts, which helps to reduce costs and structural complexity.

[0035] In a further possible design, the second end of the support portion has a hollow accommodating cavity, and the coil spring and the fixed shaft are embedded in the accommodating cavity. In this way, impurities such as dust can be prevented from entering the cavity and corroding the coil spring and affecting its performance.

[0036] In one possible design, the support portion is provided with a limiting component for limiting the range of rotation of the support portion relative to the frame. The limiting component may be any component or combination of components capable of achieving a limiting function, including, but not limited to, a limiting hole, a limiting slot, a screw limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, and the like.

[0037] In a further possible design, the limiting component is a limiting hole, the temple body passes through the limiting hole, and is fixedly connected to the second end of the coil spring.

[0038] With this design, the temple body can be restricted from rotating between the two edges of the limiting hole, so that the temple body can rotate within an area relative to the frame to achieve different states of the smart glasses.

[0039] In a further possible design, under the action of the limiting hole, the smart glasses can be in any of the following states: when the temple body is located at the first edge of the limiting hole, the smart glasses are in a folded state; when the temple body is located at the second edge of the limiting hole or between the first edge and the second edge, the smart glasses are in an expanded state.

[0040] In the above design, the smart glasses can achieve two states: folded and expanded by means of a coil spring disposed on the outside of the frame and a limiting hole for limiting the rotation of the temple body. When the smart glasses are in the folded state, the deformation of the coil spring can be a deformation amount when the glasses have no elasticity or a slight elasticity. When the smart glasses are in the expanded state, the deformation of the coil spring can be any deformation amount within the first working area, such as the minimum deformation amount, the maximum deformation amount, or an amount between the minimum and maximum deformation amounts. Moreover, in the expanded state, since the elastic force of the coil spring is substantially constant throughout the entire first working area, the smart glasses can provide a substantially constant clamping force regardless of the expanded position of the smart glasses. Therefore, the smart glasses can be adapted to users with various head widths and can meet users' requirements for wearing comfort and stability, and the smart glasses have good versatility.

[0041] Structure Three

[0042] In structure three, the coil spring adjustment portion may further include a support portion connected between the spectacles frame and the first end of the coil spring, and used to support the coil spring outside the spectacles frame.

[0043] In a possible design, the coil spring adjustment portion may further include a rotating portion, the rotating portion includes a rotating shaft, and the second end of the supporting portion and the temple body are respectively sleeved on the rotating shaft.

[0044] With this design, the temple body can rotate relative to the support portion around the rotation axis. Since the support portion is fixed on the frame, the temple body can rotate relative to the frame.

[0045] In a further possible design, the rotating portion may further include a limiting component for limiting the rotation range of the temple body. The limiting component may be, for example, a limiting hole, a limiting slot, a screw limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, or the like.

[0046] In a further possible design, the limiting component includes a protrusion, which is arranged on the rotating shaft. The temple body also includes a cover plate, a sliding groove is provided on the cover plate, the rotating shaft is covered by the cover plate at the bottom, and the protrusion is embedded in the sliding groove.

[0047] Through this design, during the rotation of the temple body, the protrusion on the rotating shaft moves in the sliding groove on the temple body, so that the temple body is restricted from rotating between the two edges of the sliding groove, thereby realizing the folding and opening states of the smart glasses.

[0048] In a further possible design, the second end of the coil spring is fixed to a rotating shaft. The rotating shaft is a free-standing shaft, meaning it is a free component not fixed to the frame or support, and is also rotatable. In this way, after the temple body rotates to the open position, it can continue to rotate to the outward-extended position under the action of the rotating shaft, and this outward-extended position is achieved by the deformation of the coil spring.

[0049] In a further possible design, the smart glasses can be in any of the following states under the action of the protrusion, the chute, and the coil spring: when the protrusion is at the first edge of the chute, the smart glasses are in a folded state; when the protrusion is at the second edge of the chute and the coil spring is in the first position, the smart glasses are in an open state; when the protrusion is at the second edge of the chute and the coil spring is in the second position, the smart glasses are in an expanded state. The diameter of the coil spring in the second position is smaller than that in the first position.

[0050] In one example of the above design, the transition between the folded and unfolded states is achieved by the protrusion and the slide groove. The coil spring is not involved in the transition or undergoes only minimal deformation. The amount of deformation of the coil spring remains essentially unchanged between the two states. In other words, the first position of the coil spring is the initial position of the coil spring. Therefore, the second operating range of the coil spring can be considered a point corresponding to the minimum deformation of the coil spring in the first operating range.

[0051] In another example of the above design, the switch between the folded and unfolded states can also be achieved by a coil spring in conjunction with the protrusion and the slide slot. The coil spring has different deformation amounts in these two states. In other words, the coil spring's first position is different from its initial position. Therefore, the coil spring's second operating range is a deformation range. The starting point of this deformation range is the coil spring's initial position, which corresponds to a deformation position one degree before the minimum deformation in the first operating range. The end of this deformation range is the coil spring's first position, which corresponds to the minimum deformation position in the first operating range.

[0052] In the above design, the smart glasses can achieve three states: folded, opened, and extended by means of a coil spring disposed on the exterior of the frame, a rotating shaft secured to the coil spring, and a protrusion and a slide groove for limiting the rotation of the temple body. The folded and opened states can be achieved by deformation of the protrusion and the slide groove, or in combination with the coil spring, while the extended state can be achieved by deformation of the coil spring. Because the elastic force of the coil spring is substantially constant throughout the entire first working area corresponding to the extended state, the smart glasses can provide a substantially constant clamping force regardless of the extended position of the smart glasses. This allows the smart glasses to fit users of various head widths and meet users' requirements for wearing comfort and stability, resulting in a high degree of versatility.

[0053] The implementation methods and beneficial effects of the above-mentioned designs will be described in detail in the following embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0068] In recent years, electronic products in the form of glasses have developed rapidly, and many smart glasses, such as virtual reality (VR) glasses, augmented reality (AR) glasses, mixed reality (MR) glasses, Bluetooth glasses, and movie glasses, have gradually entered the consumer's field of vision. Compared with ordinary optical glasses, smart glasses have added optical display modules and other electronic devices in the frame position, which significantly increases the weight of the smart glasses frame. This weight increase will lead to a decrease in user wearing comfort, and users may experience problems such as glasses sliding down and glasses putting too much pressure on the bridge of the nose during wearing. In order to solve these wearing problems, it is necessary to distribute the pressure by clamping the temples on the user's head to enhance the wearing stability of the entire device.

[0069] As described in the background art, existing smart glasses use spring hinges to provide a clamping force on the user's head. However, the deformation of the spring conforms to Hooke's law, that is, the deformation of the spring and the deformation force are linearly related, see Figure 1b. Therefore, when using this type of smart glasses, users with different head widths will generally experience different clamping forces on their heads when wearing the same smart glasses. For example, when smart glasses are worn by users with smaller head widths, although they can ensure wearing comfort, the clamping force provided is small, which can easily lead to unstable wearing. When worn by users with larger head widths, although they can ensure wearing stability, the clamping force provided is too large, which can easily lead to head clamping, making the user uncomfortable. It can be seen that the temples of existing smart glasses do not fit the user's head well and are not compatible with users with different head widths.

[0070] In view of this, the present application provides a pair of smart glasses to provide approximately constant clamping force for users with different head widths, so as to simultaneously improve the comfort and stability of the user when wearing the glasses and enhance the user's usage experience.

[0071] It should be noted that the smart glasses described in this application can be used as independent wearable devices with independent operating systems. They can complete functions such as schedule reminders, navigation, calls, and video recording by receiving user operation instructions. They can also be used to realize near-eye display scenarios, such as being able to display images of real environments and virtual objects in a real-time superimposed manner. Of course, smart glasses can also be used as interactive devices for electronic devices, used to interact with users and send interactive information to the host of the electronic device.

[0072] Based on the above content, the smart glasses provided in this application will be described in detail below with reference to Figures 2 to 11.

[0073] Please refer to Figure 2, which illustrates a schematic structural diagram of a pair of smart glasses provided herein. As shown in Figure 2, the smart glasses 10 include a frame 100 and temples 200. The temples 200 include a temple body 210 and a coil spring adjustment portion 220. The coil spring adjustment portion 220 includes a coil spring (not shown), the first end of the coil spring being connected to the frame 100, and the second end of the coil spring being connected to the temple body 210.

[0074] Continuing with FIG2 , the smart glasses 10 may further include a lens 300 mounted on the frame 100. The illustration shows the lens 300 mounted below the frame 100 as an example, but it should be understood that the lens 300 may also be mounted in any or multiple directions of the frame 100, for example, it may be centrally surrounded by the frame 100. In some examples, the lens 300 may be a lens for vision correction, such as a concave lens or a convex lens, or a lens for sun protection or eye protection, such as a flat lens, or a lens for allowing the user to view 3D or virtual images, such as a display screen that can present images such as game screens, movie screens, or navigation maps to the user.

[0075] The frame 100 may also be referred to as a middle frame or a frame. In some scenarios, the frame 100 may contain a sealed space that can be used to house electronic components related to the functions of the smart glasses 10, such as cameras and sensors. It can also be used to house optical components related to imaging, such as light sources, projectors, and optical lenses. Of course, it can also be used to arrange circuit wiring.

[0076] As will be appreciated, one end of the temple body 210 is connected to the frame 100 via the coil spring adjustment portion 220, forming the main mechanical structure of the smart glasses 10. When wearing the smart glasses 10, the temple body 210 is placed over the ear, positioning the lens 300 mounted on the frame 100 in front of the eye. Optionally, the temple body 210 may also contain an enclosed space for housing other electronic components related to the functionality of the smart glasses 10, such as circuit boards, batteries, speakers, microphones, and the like.

[0077] The coil spring adjustment portion 220 includes a coil spring and may also include other components. Please refer to Figure 3a, which is a schematic diagram of the coil spring structure of the present application. Figure 3a (A) shows a three-dimensional structural diagram of the coil spring, and Figure 3a (B) shows a cross-sectional view of the coil spring. As shown in Figure 3a, a coil spring is generally made of stainless steel strip or other relatively wide elastic material, and typically includes three or more coils. The illustration uses three coils as an example. The end of the coil spring located at the center of the coil is called the first end D of the coil spring, and the end located at the edge of the coil is called the second end F of the coil spring. One of the first end D and the second end F is fixed, and the other is free. The fixed end is stationary relative to the surrounding structural components. When the coil spring is stretched, the free end displaces relative to the fixed end, tightening the coil spring, reducing its diameter, and generating a certain amount of elastic force. When the coil spring rebounds, the free end displaces relative to the fixed end, loosening the coil spring, increasing its diameter, and reducing its elastic force.

[0078] Furthermore, a coil spring is an elastic mechanism capable of generating a stable elastic force. For example, see Figure 3b, which shows a characteristic curve of the elastic force of a coil spring in this application. The horizontal axis represents the deformation of the coil spring, and the vertical axis represents the elastic force generated by the coil spring. As shown in Figure 3b, during the initial, relatively small deformation period, the elastic force generated by the coil spring rapidly increases as the deformation increases (referred to as the rapid growth period). Once the deformation reaches a certain value (referred to as a sudden change state point, such as point a in the figure), the elastic force generated by the coil spring becomes essentially constant as the deformation continues to increase (referred to as the stable period).

[0079] Based on the aforementioned elastic characteristics of the coil spring, in order to enable the smart glasses 10 to generate a nearly constant clamping force when worn, the deformation range of the coil spring during the expansion of the temple body 210 can be configured to be within a deformation range during the stable period. For example, the initial state of the coil spring during the expansion of the temple body 210 is configured to be a state point just after crossing the sudden change state point a, such as state point b shown in the figure, and the maximum deformation state of the coil spring during the expansion of the temple body 210 is configured to be a state point located after state point b, such as state point c shown in the figure. In this way, during the entire process of the expansion of the temple body 210 (from the opening of the temple body 210 to the expansion of the temple body 210 to the maximum angle, generally not exceeding 30°, see FIG. 5 below for details), the deformation of the coil spring is within the deformation range between state points b and c shown in the figure. This deformation range is referred to as the working range of the coil spring in the expanded state (referred to as the first working range for short). The length change of the coil spring in the first working range is much smaller than the overall length of the coil spring. In this way, during the process of the smart glasses 10 being worn from the open state to the user's head, although the deformation of the coil spring changes, the elastic force it provides remains basically unchanged. Therefore, the clamping force provided by the smart glasses 10 to the user's head remains basically unchanged.

[0080] Further illustratively, in order to ensure that the clamping force provided by the smart glasses 10 when worn meets the user's wearing comfort and stability, a target clamping force that can meet the two requirements of wearing comfort and stability can be determined in advance through experiments or experience, and then the structure of the coil spring can be designed with reference to the target clamping force, such as the thickness and shape of the coil spring, so that in the elastic force characteristic curve corresponding to the designed coil spring, the relatively stable elastic force after the sudden change state point a is exactly equal to or approximately equal to the target clamping force, so that the clamping force provided by the coil spring during the wearing of the smart glasses can be compatible with users with different head widths, and can clamp the user's head tightly without being too tight, thereby effectively improving the user's wearing experience.

[0081] Furthermore, it should be noted that the temple body 210 may have other states besides the expanded state, such as a folded state or an open state (see FIG. 5 below for details). This application only defines the first operating region of the coil spring when the temple body 210 is in the expanded state, and does not define the second operating region of the coil spring when the temple body 210 is not in the expanded state. For example, the second operating region of the coil spring can be configured as a point, i.e., the deformation of the coil spring remains constant throughout the entire process from folding to opening the temple body 210, and this deformation can be configured as the minimum deformation in the first operating region. Alternatively, the second operating region of the coil spring can be configured to include a certain deformation range during the rapid rise period. In this case, the elastic force provided by the coil spring during the non-expanding state is different from the elastic force provided during the expanding state. Alternatively, the second operating region of the coil spring can be configured to be the region between the rapid rise period and the first operating region. In this case, the elastic force provided by the coil spring during the non-expanding state is substantially the same as the elastic force provided during the expanding state. And so on.

[0082] Based on the above introduction, the specific structure of the smart glasses is described in detail below. As you can understand, the temples 200 typically include two, and therefore, the temple bodies 210 and the spring adjustment parts 220 also include two. The following description uses the example of one spring adjustment part 220 connecting one temple body 210 and the frame 100.

[0083] Implementation Plan 1

[0084] Please refer to Figure 4, which illustrates a schematic diagram of the partial structure of the smart glasses in Implementation Solution 1. Figure 4(A) shows the partial structure of the smart glasses as seen from the temples after removing the innermost outer layer of the frame 100 (i.e., the side closest to the user's eyes). Figure 4(B) shows the cross-sectional structure obtained by cutting the partial structure shown in Figure 4(A) along the center of the frame in a plane parallel to the lenses. The following, in conjunction with Figures 4(A) and 4(B), details the components that may be included in the smart glasses 10.

[0085] First, referring to FIG. 4 (B), the coil spring adjustment portion 220 may include a coil spring 221 and a support portion 222. The support portion 222 is connected between the second end (end F in the figure) of the coil spring 221 and the temple body 210. For example, the first end (end E1 in the figure) of the support portion 222 is fixedly connected to the F end of the coil spring, and the second end (end E2 in the figure) of the support portion 222 is fixedly connected or rotatably connected to the temple body 210. The F end of the coil spring can be considered a free end. When the F end of the coil spring rotates relative to its fixed end (end D in the figure), it simultaneously drives the support portion 222, which is fixedly connected to the F end of the coil spring, to rotate, thereby driving the temple body 210, which is connected to the E2 end of the support portion 222, to rotate, thereby achieving outward expansion of the temple body 210 relative to the frame 100.

[0086] In one example, referring to FIG. 4 (A) or FIG. 4 (B), the frame 100 may further include a limiting component H, which is used to limit the rotation range of the support portion 222. It should be noted that the illustration uses a limiting hole as an example for the limiting component H. The support portion 222 passes through the limiting hole H, with one end connected to the F end of the coil spring 221 and the other end connected to the temple body 210. As a result, the support portion 222 is restricted from rotating between the two edges of the limiting hole H, thereby driving the temple body 210 to expand inward or outward within a small area relative to the frame 100. When the temple body 210 expands in this area, the deformation range of the coil spring 221 corresponds to the first working area of ​​the coil spring 221. It should be understood that the limiting component may also be other components or assemblies capable of achieving a limiting function, such as a limiting hole, a limiting slot, a screw limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, etc., without limitation.

[0087] In one example, please refer to (A) in Figure 4, the spring adjustment portion 220 can also include a folding adjustment portion 223, which is connected between the support portion 222 and the temple body 210, and is used to fold or open the temple body 210 relative to the support portion 222, thereby realizing the folding or opening of the temple body 210 relative to the frame 100.

[0088] It is understandable that the folding adjustment portion 223 can be any component or assembly that can achieve a folding function. For example, it can be a folding hinge. Specifically, referring to FIG4 (B), the folding adjustment portion 223 can include a rotating shaft 2231, and the E2 end of the support portion 222 also has a limiting groove. The rotating shaft 2231 is placed in the limiting groove and is fixedly connected to the E2 end of the support portion 222. The temple body 210 is sleeved on the rotating shaft 2231 and can be connected to the rotating shaft 2231 by screw locking (not shown in the figure). In this way, when the smart glasses 10 are switched to the folded state, the temple body 210 can be pushed in the counterclockwise direction shown in the figure, so that the temple body 210 rotates counterclockwise around the rotating shaft 2231 to the edge of the limiting groove shown in the figure I1, thereby folding the temple body 210 below the figure of the frame 100. On the contrary, when the smart glasses 10 are switched to the open state, the temple body 210 can be pushed in the clockwise direction as shown in the figure in the folded state, so that the temple body 210 rotates clockwise around the rotating shaft 2231 to the edge I2 of the limit groove as shown, so that the temple body 210 is opened relative to the frame 100, and at the same time, is fixed in the open position under the action of the rebound force provided by the screw lock.

[0089] In one example, referring to FIG. 4 (A) and FIG. 4 (B), the first end (D end in the figure) of the coil spring can be fixed to the frame 100, specifically, fixed inside the frame 100. For example, the frame 100 includes a frame body 110, and the D end of the coil spring 221 is fixed inside the frame body 110, for example, by welding, gluing, riveting, threading, etc.

[0090] Alternatively, in a specific fixing method, please continue to refer to Figure 4 (B), a fixed shaft 120 is provided in the frame 110, and a first slot is defined in the fixed shaft 120. The D end of the coil spring 221 is inserted into the first slot so that it is clamped by the first slot and thus fixed in the frame 110. Fixing by slotting and clamping is convenient to prepare and does not require the introduction of additional fixing parts, which helps to reduce costs and structural complexity.

[0091] In a further example, please continue to refer to (B) in Figure 4, the E1 end of the support portion 222 can also have a hollow accommodating cavity, and the coil spring 221 and the fixed shaft 120 are embedded in the accommodating cavity, so as to prevent dust and other impurities from entering the cavity and corroding the coil spring 221 and affecting the performance of the coil spring 221.

[0092] Optionally, in order to ensure the integrity of the accommodating cavity structure, referring to FIG. 4 (A), the frame 110 may further include a cover 130 , which covers the accommodating cavity to wrap the coil spring 221 and the fixed shaft 120 inside.

[0093] In addition, in order to maintain the stability of the cover plate 130 on the accommodating cavity and prevent it from moving, the cover plate 130 can also be fixedly connected to the frame 110. For example, please continue to refer to Figure 4 (A), the frame 110 has at least one support column, and at least one support column is screwed together with the cover plate 130 by screws, thereby fixing the cover plate 130 to the frame 110. It should be understood that Figure 4 is an example of two support columns 141 and 142 threadedly fixing the cover plate, but in practice, one or more support columns can also be provided, and the support columns and the cover plate can also be fixed by other methods, which are not limited to specific methods.

[0094] In one example, the F end of the coil spring can be fixed to the E1 end of the support portion 222 by welding, gluing, riveting, threading, etc. For example, in one specific fixing method, please continue to refer to Figure 4 (B), the E1 end of the support portion 222 has a hollow accommodating cavity, and the outer shell of the accommodating cavity has a first opening. The F end of the coil spring 221 is bent and inserted into the first opening to engage with the outer shell of the accommodating cavity.

[0095] The above content introduces the possible structures of the smart glasses 10. The possible states of the smart glasses 10 will be described below.

[0096] The smart glasses in Implementation Solution 1 can be realized in three states: folded, open, and extended, as shown in Figure 5. Furthermore, Figure 6 shows a partial cross-sectional structure diagram of the smart glasses in each state. For example, Figure 6 (A) shows a partial cross-sectional structure diagram of the smart glasses in the folded state, Figure 6 (B) shows a partial cross-sectional structure diagram of the smart glasses in the open state, and Figure 6 (C) shows a partial cross-sectional structure diagram of the smart glasses in the extended state.

[0097] First, referring to FIG. 6 (A), when the supporting portion 222 is located at the first edge H1 of the limiting component and the folding adjusting portion 223 is in the folded state, the smart glasses 10 are in the folded state.

[0098] Next, referring to FIG6(B), when the support portion 222 is located at the first edge H1 of the stopper and the folding adjustment portion 223 is in the open state, the smart glasses 10 are in the open state. For example, in the folded state shown in FIG6(A), the temple body 210 is pushed clockwise as shown, rotating around the support portion 222 from the upper limit groove edge I1 shown in the figure to the upper limit groove edge I2 shown in the figure, thereby unfolding the temple body 210, thereby switching the smart glasses 10 from the folded state to the open state. At this time, the temple body 210 is in the minimum extended position.

[0099] It should be noted that, according to the position-limiting method shown in Figures 6(A) and 6(B), the process of rotating the temple body 210 from the folded state to the open state, or vice versa, is entirely accomplished by the folding adjustment portion 223, without any involvement of the coil spring 221. In this case, during the rotation of the temple body 210 from the folded state to the open state, the support portion 222 remains located at the first edge H1 of the position-limiting component and does not rotate. Therefore, the deformation of the coil spring 221 remains unchanged, and the second operating region of the coil spring 221 remains at a single point, corresponding to the minimum deformation within the coil spring's first operating region, i.e., the deformation corresponding to point b in the state shown in Figure 3b.

[0100] It is understood that the state switching method shown in Figures 6(A) and 6(B) is only one possible example. In another example, the coil spring 221 and the folding adjustment portion 223 can also be used together to achieve switching between the folded state and the open state. For example, when the folding adjustment portion 223 is used to unfold the temple body, the deformation of the coil spring 221 is also used to drive the temple body 210 to further unfold, so that when the smart glasses 10 are in the open state, the support portion 222 is located at a position between the first edge H1 and the second edge H2 of the limiting component, and the folding adjustment portion 223 is in the open state. In this case, since the coil spring 221 will also have a small deformation during the opening process of the smart glasses 10, the second working area of ​​the coil spring 221 remains as a deformation area. The starting point of the deformation area corresponds to a deformation before the deformation corresponding to the state point b shown in Figure 3b, and the end of the deformation area corresponds to the deformation corresponding to the state point b shown in Figure 3b. When the deformation area is in a stable period, the elastic force provided by the coil spring 221 in the second working area is basically the same as the elastic force provided during the expansion process. When the deformation area is in a rapid rising period, the elastic force provided by the coil spring 221 in the second working area is different from the elastic force provided during the expansion process.

[0101] Furthermore, referring to FIG6 (C), when the support portion 222 is located at the second edge H2 of the retaining member or somewhere between the first edge H1 and the second edge H2 (the figure shows the support portion 222 located at the second edge H2), and the folding adjustment portion 223 is in the open state, the smart glasses 10 are in the outward expansion state. For example, in the open state shown in FIG6 (B), if the diameter of the user's head is larger than the distance between the two temples in the open state, the resistance of the user's head against the temple body 210 during the process of wearing the smart glasses 10 on the user's head will cause the temple body 210 to continue to rotate in the clockwise direction shown in the figure. However, at this point, the temple body 210 is already at the edge I2 of the retaining groove shown in the figure, and the temple body 210 can no longer rotate along the support portion 222. Therefore, the temple body 210 will drive the support portion 222 to rotate clockwise, which in turn drives the F end of the coil spring 221 fixed to the E1 end of the support portion 222 to rotate clockwise. Since the D end of the coil spring 221 is fixed to the frame 100, the rotation of the F end causes the coil spring 221 to be tightened, the diameter of the coil spring 221 becomes smaller, and the interval between any two adjacent coils in the coil spring 221 becomes smaller. In order to overcome this tightening trend, the coil spring 221 itself will generate an opposite elastic force, that is, a clamping force.

[0102] In addition, as the outward expansion angle increases, although the clamping force generated by the coil spring 221 also increases, as described in the first working area in Figure 3b above, the elastic force generated by the coil spring 221 is substantially constant between the minimum outward expansion position (the support portion 222 is located at the first edge H1 of the limiting component, and the coil spring 221 is at the deformation corresponding to the state point b shown in Figure 3b) and the maximum outward expansion position (the support portion 222 is located at the second edge H2 of the limiting component, and the coil spring 221 is at the deformation corresponding to the state point c shown in Figure 3b), thereby ensuring that the clamping force of the smart glasses 10 on the head is substantially constant. In this way, users with different head widths can experience the same clamping force when wearing the smart glasses 10. Users with larger head widths will not have their heads pinched, and users with smaller head widths will not feel unstable when wearing the glasses, which helps to improve both wearing comfort and wearing stability.

[0103] Using the smart glasses structure of the above-mentioned implementation scheme 1, the three states of folding, opening, and expansion can be achieved through the coil spring provided inside the frame and the folding adjustment portion provided outside the frame. When the user is not wearing the smart glasses, the smart glasses can be folded and stored using the folding adjustment portion. When the user is wearing the smart glasses, the smart glasses can be opened using the folding adjustment portion, and the temples can be expanded outwards to match the width of the head using the coil spring. Moreover, in the expanded state, no matter where the smart glasses are expanded outwards, the smart glasses can provide a substantially constant clamping force, so that the smart glasses can be adapted to users of various head widths, meeting the user's needs for wearing comfort and stability, and the smart glasses have good versatility.

[0104] Implementation Plan 2

[0105] Compared to the smart glasses structure in Implementation Plan 1, Implementation Plan 2 simplifies the smart glasses by eliminating the folding adjustment mechanism. Only the coil spring-related components remain, and the coil spring is externally positioned, allowing the smart glasses to operate in both the folded and expanded states. The following details the specific structure of the smart glasses in Implementation Plan 2.

[0106] Please refer to Figure 7, which illustrates a schematic diagram of the partial structure of the smart glasses in Implementation Solution 2. Figure 7(A) shows the partial structure of the smart glasses as seen from the temples after removing the innermost outer shell of the frame 100 (i.e., the side closest to the user's eyes). Figure 7(B) shows the cross-sectional structure obtained by cutting the partial structure shown in Figure 7(A) along the center of the frame in a plane parallel to the lenses. The following, in conjunction with Figures 7(A) and 7(B), details the components that may be included in the smart glasses 10.

[0107] First, referring to FIG. 7B , the coil spring adjustment portion 220 may include a coil spring 221 and a support portion 222. The support portion 222 is connected between the frame 100 and a first end (end D in the figure) of the coil spring 221, and is used to support the coil spring 221 outside the frame 100. The end D of the coil spring 221 can be considered as a fixed end, and the free end (end F in the figure) of the coil spring 221 is connected to the temple body 210. When the end F of the coil spring 221 rotates relative to the end D, it will synchronously drive the temple body 210 connected to the end F of the coil spring 221 to rotate, thereby achieving rotation of the temple body 210 relative to the frame 100.

[0108] In one example, please continue to refer to (B) in Figure 7 , the frame 100 has a first opening H, the support portion 222 passes through the first opening H, the first end (end E1 shown in the figure) is fixed in the frame 100, and the second end (end E2 shown in the figure) is fixedly connected to the D end of the coil spring 221, so that the D end of the coil spring 221 can be fixedly connected to the frame 100.

[0109] It can be understood that Figure 7 takes the example of the E1 end of the support part 222 being fixed to the frame 100 by bolts, but the actual smart glasses 10 can also be fixed by any one or more methods such as welding, rivets, magnetism, bonding, clamping, hanging, locking, riveting or snapping, etc., without specific limitation.

[0110] In a further example, end E2 of support portion 222 can also be fixedly connected to end D of coil spring 221 using any of the aforementioned fixing methods. For example, in one specific fixing method, as shown in Figure 7 (B), end E2 of support portion 222 includes a fixed shaft 231 having a first slot defined therein. End D of coil spring 221 is inserted into the first slot, thereby being captured and secured to end E2 of support portion 222. This slotted, engaging fixing method is convenient to manufacture and eliminates the need for additional fixings, thereby reducing cost and structural complexity.

[0111] In a further example, please continue to refer to (B) in Figure 7, the E2 end of the support portion 222 can also have a hollow accommodating cavity, and the coil spring 221 and the fixed shaft 231 are embedded in the accommodating cavity, so as to prevent dust and other impurities from entering the cavity and corroding the coil spring 221 and affecting the performance of the coil spring 221.

[0112] Optionally, in order to ensure the integrity of the accommodating cavity structure, please refer to (A) in Figure 7, the accommodating cavity can also be sealed by the outer shell on the temple body 210 and the outer shell of the support part 222 to wrap the coil spring 221 and the fixed shaft 231 inside.

[0113] In one example, the end E2 of the support portion 222 may further include a limiting component, which is used to limit the rotation range of the temple body 210 relative to the support portion 222. The limiting component can be any component or combination of components that can achieve a limiting function, such as but not limited to: a limiting hole, a limiting slot, a screw limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, etc.

[0114] In a further example, using a limiting hole as the limiting component, as shown in FIG7B , the support portion 222 has a limiting hole K at end E2 (the limiting hole K is shown as being provided on the housing of the accommodating cavity). The temple body 210 passes through the limiting hole K and is fixedly connected to the F end of the coil spring 221. Thus, the temple body 210 can be restricted from rotating between the two edges of the limiting hole K.

[0115] The above content introduces the possible structures of the smart glasses 10. The possible states of the smart glasses 10 will be described below.

[0116] The smart glasses in Implementation Solution 2 can be implemented in two states: a folded state and an expanded state, as shown in Figure 8. Furthermore, Figure 9 shows a partial cross-sectional structure diagram of the smart glasses in each state. For example, Figure 9 (A) shows a partial cross-sectional structure diagram of the smart glasses in the folded state, and Figure 9 (B) shows a partial cross-sectional structure diagram of the smart glasses in the expanded state.

[0117] First, referring to FIG9 (A), when the temple body 210 is located at the first edge H1 of the limiting hole, the smart glasses 10 are in a folded state. In the folded state, the coil spring 221 is not deformed or has a small deformation.

[0118] Next, referring to FIG9 (B), when the temple body 210 is located at the second edge H2 of the retaining hole or somewhere between the first edge H1 and the second edge H2 (the figure shows the temple body 210 located at the second edge H2 of the retaining hole), the smart glasses 10 are in the outward-expanded state. For example, when the smart glasses 10 are placed on the user's head from the folded state shown in FIG9 (A), the temple body 210 rotates clockwise within the retaining hole, thereby driving the F end of the coil spring 221 to which it is fixed to rotate together until the temple body 210 is clamped on both sides of the user's head. Because the D end of the coil spring 221 is fixed to the frame 100, the rotation of the F end causes the coil spring 221 to be tightened, reducing its diameter and reducing the distance between any two adjacent coils of the coil spring 221. To overcome this tightening tendency, the coil spring 221 generates an opposing elastic force, i.e., a clamping force. In addition, after the user finishes wearing the glasses and takes off the smart glasses 10, the temple body 210 will automatically rebound to the folded state shown in FIG. 9 (A) under the elastic force of the coil spring.

[0119] It should be noted that the wearing process of the smart glasses 10 in the second implementation scheme may include two stages:

[0120] In stage 1, the user unfolds the temple body 210 from the folded state shown in FIG9 (A). During this process, the temple body 210 rotates clockwise in the limiting hole under the influence of the user's manual force, assuming that it rotates to position H3 of the limiting hole shown in FIG9 (B). Position H3 can be designed based on the head width of the user group of the smart glasses 10. For example, it can be configured to be the position of the temple body 210 when the user with the smallest head width wears the smart glasses 10.

[0121] In the second stage, the user puts the manually opened smart glasses 10 on the head. During this process, the temple body 210 will stop at position H3 under the action of the head resistance, or continue to rotate clockwise until it rotates to a position that is adapted to the width of the user's head.

[0122] The second stage corresponds to the first operating range of the coil spring 221. The first operating range can be designed in accordance with the method shown in FIG. 3b . For example, the deformation of the coil spring 221 when the temple body 210 is at the minimum outward expansion position H3 is configured to correspond to the deformation corresponding to state point b shown in FIG. 3b , and the deformation of the temple body 210 when the temple body 210 is at the maximum outward expansion position H2 is configured to correspond to the deformation corresponding to state point c shown in FIG. In this way, for users with different head widths, although the temple body 210 ultimately stops at different positions, by pre-designing the rotation range of the temple body 210 between the minimum outward expansion position H3 and the maximum outward expansion position H2 to correspond exactly to the deformation range of the coil spring 221 between state points b and state point c shown in FIG. 3b , the elastic force generated by the coil spring 221 during the rotation of the temple body 210 can be kept substantially constant, thereby ensuring that the clamping force of the smart glasses 10 for users with different head widths is substantially constant.

[0123] In addition, the above-mentioned stage 1 corresponds to the second working area of ​​the coil spring 221. The second working area can be configured in various situations, such as:

[0124] In one possible design, the second working area can be configured as the area between the sudden change state point a or a state point thereafter and the state point b shown in FIG3 b . In this case, the second working area is in a stable period. During the process of switching the temple body 210 from the folded state to the opened state, although the deformation of the coil spring 221 changes, the elastic force provided by the coil spring 221 remains substantially unchanged, and is approximately equal to the elastic force provided by the coil spring 221 in the expanded state.

[0125] In another possible design, the second working region can be configured as a region between a state point before the sudden change state point a and a state point b as shown in FIG3b . In this case, the second working region transitions from a rapid growth period to a stable period. During the process of switching the temple body 210 from the folded state to the open state, the deformation of the coil spring 221 changes, and the elastic force provided by the coil spring 221 also changes. The elastic force provided by the coil spring 221 gradually increases from an elastic force less than the constant elastic force corresponding to the first working region to the constant elastic force corresponding to the first working region. For example, assuming that the second working region is configured to range from no deformation or slight deformation to a deformation corresponding to the state point b shown in FIG3b , during the process of switching the temple body 210 from the folded state to the open state, the elastic force provided by the coil spring 221 gradually increases from 0 to the constant elastic force corresponding to the first working region.

[0126] The smart glasses structure of the second implementation scheme can achieve both folded and expanded states through coil springs and position-limiting components located on the exterior of the frame. Furthermore, in the expanded state, the smart glasses maintain a substantially constant clamping force regardless of their expanded position. This allows the smart glasses to fit users of varying head widths and meet their needs for both comfort and stability, resulting in a highly versatile design.

[0127] Implementation Plan 3

[0128] Compared to the smart glasses structure in Implementation Plan 2, Implementation Plan 3 adds a rotating portion that enables the glasses to be opened. This portion is secured to one end of a coil spring. A specially shaped slot is also provided in the component that mates with the rotating portion, enabling the glasses to be folded, opened, and extended. The specific structure of the smart glasses in Implementation Plan 3 is detailed below.

[0129] Please refer to Figure 10, which illustrates a schematic diagram of the partial structure of the smart glasses in Implementation Solution 3. Figure 10(A) shows the partial structure of the smart glasses as seen from the temples after removing the innermost outer shell of the frame 100 (i.e., the side closest to the user's eyes). Figure 10(B) shows the cross-sectional structure obtained by cutting the partial structure shown in Figure 10(A) along the center of the frame in a plane parallel to the lenses. The following, in conjunction with Figures 10(A) and 10(B), details the components that may be included in the smart glasses 10.

[0130] First, referring to FIG. 10B , the coil spring adjustment portion 220 may include a coil spring 221 and a support portion 222. The support portion 222 is connected between the frame 100 and a first end (end F in the figure) of the coil spring 221. For example, the frame 100 may have a first opening H. The support portion 222 passes through the first opening H, with a first end (end E1 in the figure) secured to the frame 100 and a second end (end E2 in the figure) secured to end F of the coil spring 221, thereby supporting the coil spring 221 outside the frame 100.

[0131] It should be noted that Figure 10 takes the example of the E1 end of the support part 222 being fixed to the frame 100 by screws, and the F end of the coil spring 221 being fixed to the E2 end of the support part 222 by gluing. However, it should be understood that other fixing methods can also be used in the actual smart glasses 10. For example, a groove can be opened at the E2 end of the support part 222, and the F end of the coil spring 221 can be embedded in the groove to achieve the fixation of the F end of the coil spring 221 and the E2 end of the support part 222, etc., and there is no specific limitation.

[0132] In one example, referring to FIG. 10 (A) and FIG. 10 (B), the coil spring adjustment portion 220 may further include a rotating portion 223, wherein the rotating portion 223 includes a rotating shaft 2231. The end E2 of the support portion 222 and the temple body 210 are respectively mounted on the rotating shaft 2231. With this design, the temple body 210 can rotate relative to the support portion 222 about the rotating shaft 2231, thereby achieving rotation of the temple body 210 relative to the frame 100.

[0133] It should be noted that the rotating shaft 2231 can be understood as a suspended shaft, that is, the rotating shaft 2231 itself is a free part and is not fixed to the frame 100 or the support part 222, and the rotating shaft 2231 itself can also rotate.

[0134] In a further example, the rotating portion 223 may further include a limiting component for limiting the rotation range of the temple body 210 around the rotating shaft 2231. The limiting component may be, for example, a limiting hole, a limiting slot, a screw limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, etc.

[0135] In a specific design of a limiting component, referring to Figures 10(A) and 10(B), a rotating shaft 2231 includes a raised portion 2232. The temple body 210 includes a cover plate 211, which defines a slot 212. The rotating shaft 2231 is covered by the cover plate 211, and the raised portion 2232 is embedded in the slot 212. As the temple body 210 rotates, the slot 212 on the temple body 210 is blocked at the edge by the raised portion 2232, thereby limiting the rotation of the temple body 210 within the range where the two edges of the slot 212 are blocked. This range of rotation corresponds to the state between the folded and unfolded states of the smart glasses 10. For example, when the right edge of the slot 212 is blocked by the raised portion 2232, the temple body 210 is folded below the frame 100, and the smart glasses 10 are in the folded state. When the temple body 210 is rotated clockwise in the figure in the folded state, the slide groove 212 on the temple body 210 slides clockwise along the protrusion 2232. When the upper edge of the slide groove 212 is caught by the protrusion 2232, the temple body 210 unfolds and the smart glasses 10 are in the open state. It can be understood that the position of the protrusion 2232 can remain unchanged during the process of the smart glasses 10 switching from the folded state to the open state. The sliding of the slide groove 212 along the protrusion 2232 realizes the switching of the smart glasses 10 between the two states.

[0136] In a further example, to enable the smart glasses 10 to have an outward expansion state, please continue to refer to FIG. 10 (B), where the D end of the coil spring 221 is fixed to the rotating shaft 2231. The D end of the coil spring can be considered a free end. Thus, during the clockwise rotation of the temple body 210 as shown, even if the groove 212 on the temple body 210 is stuck by the protrusion 2232 at the upper edge as shown, preventing the temple body 210 from further rotating around the rotating shaft 2231, since the rotating shaft 2231 is suspended, the temple body 210 can drive the stuck protrusion 2232 to rotate clockwise, thereby driving the rotating shaft 2231 on which the protrusion 2232 is located to rotate, and further driving the D end of the coil spring 221 fixed to the rotating shaft 2231 to rotate. Through the displacement of the D end of the coil spring 221 relative to the F end, the temple body 210 can be expanded relative to the frame 100.

[0137] In a further example, the D-end of the coil spring 221 can be secured to the rotating shaft 2231 by any one or more of welding, gluing, rivets, magnetism, clamping, hanging, locking, riveting, or snapping. For example, in one specific securing method, as shown in FIG10(B), the rotating shaft 2231 is provided with a first slot. The D-end of the coil spring 221 is inserted into the first slot, thereby being retained by the first slot and thus secured to the rotating shaft 2231. This slotted, snap-fitting securing method is convenient to manufacture and eliminates the need for additional fasteners, thus helping to reduce cost and structural complexity.

[0138] In a further example, please continue to refer to (B) in Figure 10, the E2 end of the support portion 222 can also have a hollow accommodating cavity, and the coil spring 221 and the rotating shaft 2231 are embedded in the accommodating cavity, so as to prevent dust and other impurities from entering the cavity and corroding the coil spring 221 and affecting the performance of the coil spring 221.

[0139] Optionally, in order to ensure the integrity of the accommodating cavity structure, please refer to (A) in Figure 10, the accommodating cavity can also be sealed by the outer shell on the temple body 210 and the outer shell of the support part 222 to wrap the coil spring 221 and the rotating shaft 2231 inside.

[0140] The above content introduces the possible structures of the smart glasses 10. The possible states of the smart glasses 10 will be described below.

[0141] The smart glasses in Implementation Scheme 3 can be realized in three states: folded, open, and extended, as shown in Figure 5. Furthermore, Figure 11 shows a partial cross-sectional structure diagram of the smart glasses in each state. For example, Figure 11 (A) shows a partial cross-sectional structure diagram of the smart glasses in the folded state, Figure 11 (B) shows a partial cross-sectional structure diagram of the smart glasses in the open state, and Figure 11 (C) shows a partial cross-sectional structure diagram of the smart glasses in the extended state.

[0142] First, referring to FIG11 (A), when the protrusion 2232 is located at the first edge H1 of the slide groove 212, the smart glasses 10 are in a folded state. In the folded state, the coil spring 221 is in an initial position.

[0143] Next, referring to Figures 10 and 11(B), when the raised portion 2232 is located at the second edge H2 of the chute 212 and the coil spring 221 is in the first position, the smart glasses 10 are in the open state. Alternatively, the first position may refer to the initial position of the coil spring 221. In this case, the process of switching the smart glasses 10 from the folded state to the open state, or from the switched state to the folded state, can be entirely accomplished by the raised portion 2232 and the chute 212, without the coil spring 221 being involved. Thus, the initial position of the coil spring 221 can be the position corresponding to the deformation amount of state point b shown in Figure 3b. For example, when opening the smart glasses 10 from the folded state shown in Figure 11(A), the temple body 210 rotates clockwise, driving the chute 212 on the temple body 210 to rotate clockwise. When the second edge H2 of the chute 212 is engaged by the raised portion 2232, the temple body 210 unfolds, and the smart glasses 10 switches to the open state. In this way, when the smart glasses 10 switch from the folded state to the open state, the position of the protrusion 2232 remains unchanged, and therefore the position of the rotating shaft 2231 where the protrusion 2232 is located also remains unchanged. Compared with the folded state, the rotating shaft 2231 in the open state does not rotate, and therefore, the D end of the coil spring 221 fixed to the rotating shaft 2231 does not rotate, and the coil spring 221 does not deform, and the coil spring still maintains the deformation amount corresponding to the state point b shown in Figure 3b. Conversely, when the smart glasses 10 change from the open state shown in FIG. 11 (B) to the folded state shown in FIG. 11 (A), the temple body 210 rotates counterclockwise as shown. Due to the deformation resistance of the coil spring 221, the shaft 2231 and the protrusion 2232 provided thereon remain almost stationary relative to the smart glasses 10. The temple body 210 and the shaft 2231 rotate relative to each other, and the groove 212 on the temple body 210 slides counterclockwise along the protrusion 2232 on the shaft 2231 until the first edge H1 of the groove 212 is caught by the protrusion 2232. During this process, the coil spring 221 does not deform significantly and always maintains the deformation corresponding to the state point b shown in FIG. 3 b.

[0144] It is understood that in other examples, the first position may also refer to a position where the diameter of the coil spring 221 is smaller than the diameter of the initial position. In this case, the smart glasses 10 switch from the folded state to the open state or from the switched state to the folded state. This process is achieved by the coil spring 221, the protrusion 2232, and the slide 212. Therefore, the initial position of the coil spring 221 can be a position before the deformation amount corresponding to the state point b shown in Figure 3b, and the first position of the coil spring 221 can be a position corresponding to the deformation amount corresponding to the state point b shown in Figure 3b. Specifically, during the process of unfolding the temple body 210 using the protrusion 2232 and the slide 212, the deformation of the coil spring 221 can be simultaneously used to drive the rotation shaft 2231 to rotate, thereby driving the temple body 210 to further unfold. When the smart glasses 10 are in the open state, the coil spring 221 is located at a position between the initial position and the second position (i.e., the first position), and the protrusion 2232 is located at the second edge H2 of the slide 212. In this case, since the coil spring 221 rotates from the initial position to the first position during the opening of the smart glasses 10, the second working area of ​​the coil spring 221 corresponds to the deformation area between the deformation amount of the initial position and the deformation amount of the first position. When the deformation area is in a stable period, the elastic force provided by the coil spring 221 is basically the same as the elastic force provided during the outward expansion process. When the deformation area is in a rapid rising period, the elastic force provided by the coil spring 221 is different from the elastic force provided during the outward expansion process.

[0145] Furthermore, referring to Figures 10 and 11 (C), when the protrusion 2232 is located at the second edge H2 of the chute and the coil spring 221 is in the second position, the smart glasses 10 are in the outward-expanded state. The second position refers to a position where the diameter of the coil spring 221 is smaller than that in the first position, or in other words, a position where the elastic force generated by the coil spring 221 is greater than that in the first position. For example, it can be at the end or a position in the middle of the first working area of ​​the coil spring 221, i.e., the position corresponding to the deformation amount of state point c shown in Figure 3b, or a position with a certain deformation amount between states b and c. For example, when the smart glasses 10 are worn on the head from the open state shown in FIG11 (B), the temple body 210 continues to rotate in the clockwise direction shown in the figure under the action of the head resistance. Since the temple body 210 is stuck by the protrusion 2232, the temple body 210 forms a hard contact with the protrusion 2232. The temple body 210 drives the protrusion 2232 to rotate clockwise, and then drives the shaft 2231 where the protrusion 2232 is located to rotate clockwise. The rotation of 2231 in turn drives the D end of the coil spring 221 fixed to the rotating shaft 2231 to rotate. Since the F end of the coil spring 221 is fixed to the frame 100, the rotation of the D end causes the coil spring 221 to be wound tightly, reducing the diameter of the coil spring 221 and reducing the distance between any two adjacent coils of the coil spring 221. To overcome this tightening trend, the coil spring 221 itself generates an opposing elastic force, that is, a clamping force. The clamping force of the coil spring 221 clamps the temple body 210 on both sides of the user's head. Furthermore, because the elastic force generated by the coil spring 221 in the first working area is pre-designed to be substantially constant, the clamping force on the head is also substantially constant when the smart glasses 10 are expanded to different positions.

[0146] The smart glasses structure of the third implementation scheme can achieve three states: folded, opened, and expanded, using a coil spring disposed on the exterior of the frame, a suspended shaft, and a protrusion disposed on the shaft. Furthermore, in the expanded state, the smart glasses maintain a substantially constant clamping force regardless of their expanded position. This allows the smart glasses to fit users of varying head widths and meet their needs for both comfort and stability, resulting in a highly versatile smart glasses.

[0148] Furthermore, in any of the aforementioned implementations 1 through 3, the relevant components of the frame and temples are electrically connectable via cables or flexible printed circuits (FPCs).
