Description

Technical Field

[0001] The present application relates to the field of mechanical technology, and in particular to a pair of smart glasses. Background Art

[0002] As a new type of intelligent wearable device, smart glasses combine the latest information technology (IT) with the functions of traditional glasses. They are becoming increasingly popular due to their advantages such as portability, ease of use and rich functions.

[0003] Usually, when wearing smart glasses, the temples need to be placed at the ears to form a clamping force on the head. In order to make the temples fit the head better, please refer to Figure 1a Existing smart glasses usually have spring hinges at the connection between the temples and the frame, and provide a clamping force on the head by compressing or stretching the spring in the spring hinge. However, the temples of existing smart glasses do not fit the user's head well, and users with small heads are prone to unstable wearing, while users with large heads are prone to head clamping and uncomfortable wearing, and are not suitable for users with different head widths.

[0004] In summary, there is still room for further research on the structural design of smart glasses. Summary of the invention

[0005] The present application provides a pair of smart glasses for providing a substantially constant clamping force to suit users with different head widths.

[0006] The present application provides a kind of smart glasses, including a frame and temples, the temples including temple bodies and coil spring adjustment parts, the coil spring adjustment parts including coil springs, the first end of the coil springs being connected to the frame, and the second end of the coil springs being connected to the temple bodies.

[0007] In the above design, the frame and the temple body are connected by a coil spring, and the elastic force 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, so as to utilize the basically constant elastic force generated by the deformation of the coil spring 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.

[0008] In one possible design, a clamping force that can simultaneously meet wearing comfort and wearing stability can be pre-tested, and then, with reference 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, such as 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.

[0009] 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.

[0010] Exemplarily, this application provides the following three possible smart glasses structures.

[0011] Structure 1

[0012] In structure 1, the coil spring adjustment portion may further include a support portion, which is connected between the second end of the coil spring and the temple body.

[0013] Through this design, the support portion can connect the second end of the coil spring to the outside of the frame to achieve connection with the temple body outside the frame.

[0014] 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.

[0015] 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.

[0016] In a further possible design, a fixed shaft is provided in the frame, a first slot is provided on the fixed shaft, and the first end of the coil spring is embedded in the first slot.

[0017] Through this design, the first end of the coil spring can be clamped by the first groove, so as to be 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.

[0018] In a further possible design, the support portion has a hollow accommodating cavity, and the coil spring and the fixed shaft are embedded in the accommodating cavity, so as to prevent dust and other impurities from entering the cavity and corroding the coil spring and affecting the performance of the coil spring.

[0019] 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 to achieve a fixed connection between the second end of the coil spring and the support portion.

[0020] In a 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.

[0021] In a further possible design, the frame is provided with a limiting component, which is used to limit the rotation 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 that can achieve the 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.

[0022] 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.

[0023] 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.

[0024] In the above design, the smart glasses can achieve three states of folding, opening and expansion through the coil spring arranged inside the frame and the folding adjustment part arranged outside the frame. Among them, the folding state and the opening state are realized by the folding adjustment part, and the coil spring is not involved. Therefore, the deformation amount of the coil spring in these two states or between these two states remains unchanged, and the second working area of ​​the coil spring is a point, which can correspond to the minimum deformation amount of the coil spring in the first working area. On the contrary, the expansion state is realized by the deformation of the coil spring. Since the elastic force of the coil spring in the entire first working area is basically constant, no matter where the smart glasses expand to, the smart glasses can provide a basically constant clamping force, so that the smart glasses can be adapted to users with various head widths and can meet the user's requirements for wearing comfort and stability. The smart glasses have good versatility.

[0025] It is understandable that in some other possible designs, when the smart glasses are in the open state, the support portion may also be located between the first edge and the second edge of the limiting component, and the folding adjustment portion is in the open state. In other words, the open state of the smart glasses is achieved by the coil spring in combination with the folding adjustment portion. In this case, the second working area of ​​the coil spring is a deformation area, the starting point of the deformation area corresponds to a deformation before the minimum deformation in the first working area, and the end of the deformation area corresponds to the minimum deformation in the first working area.

[0026] Structure 2

[0027] In structure 2, 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.

[0028] 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.

[0029] With this design, the first end of the coil spring can be fixedly connected to the frame. In this case, 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.

[0030] 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.

[0031] In the above design, the first end of the coil spring can be caught by the first groove, so as to be 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.

[0032] 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, so as to prevent dust and other impurities from entering the cavity and corroding the coil spring and affecting the performance of the coil spring.

[0033] In a possible design, the support portion is provided with a limiting component, which is used to limit the rotation range of the support portion relative to the lens frame. The limiting component may be any component or combination of components that can achieve the 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.

[0034] 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.

[0035] Through this design, the temple body can be restricted to rotate between the two edges of the limiting hole, so that the temple body can rotate within a region relative to the frame to achieve different states of the smart glasses.

[0036] 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.

[0037] In the above design, the smart glasses can achieve two states, folding and expansion, by means of the coil springs arranged outside the frame and the limiting holes for limiting the rotation of the temple bodies. When the smart glasses are in the folded state, the deformation of the coil springs may be the deformation when they are not elastic or have a small elasticity. When the smart glasses are in the expansion state, the deformation of the coil springs may be any deformation in the first working area, such as the minimum deformation, the maximum deformation, or between the minimum deformation and the maximum deformation. Moreover, in the expansion state, since the elastic force of the coil springs in the entire first working area is basically constant, no matter where the smart glasses are expanded, the smart glasses can provide a basically constant clamping force, so that the smart glasses can be adapted to users with various head widths and can meet the user's requirements for wearing comfort and stability, and the smart glasses have good versatility.

[0038] Structure Three

[0039] In structure three, 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.

[0040] 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.

[0041] 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.

[0042] In a further possible design, the rotating part may also be provided with a limiting component, which is used to limit the rotation range of the temple body, wherein the limiting component may be, for example, a limiting hole, a limiting slot, a spiral limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, etc.

[0043] 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 slide groove is provided on the cover plate, the rotating shaft is covered at the bottom by the cover plate, and the protrusion is embedded in the slide groove.

[0044] 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 state and the opening state of the smart glasses.

[0045] In a further possible design, the second end of the coil spring is fixed to the shaft. The shaft is a suspended shaft, that is, the shaft itself is a free part, not fixed to the frame or the support part, and the shaft itself can also rotate. In this way, after the temple body rotates to the open state, it can continue to rotate to the outward expansion state under the rotation of the shaft, and the outward expansion state is provided by the deformation of the coil spring.

[0046] In a further possible design, under the action of the protrusion, the slide slot and the coil spring, the smart glasses can be in any of the following states: when the protrusion is located at the first edge of the slide slot, the smart glasses are in a folded state; when the protrusion is located at the second edge of the slide slot and the coil spring is located at the first position, the smart glasses are in an open state; when the protrusion is located at the second edge of the slide slot and the coil spring is located at the second position, the smart glasses are in an expanded state. The diameter of the coil spring in the second position is smaller than the diameter of the coil spring in the first position.

[0047] In an example of the above design, the switch between the folded state and the opened state can be realized by the protrusion and the slide groove, the coil spring does not participate in or has only a small deformation, and the deformation amount of the coil spring in these two states is basically unchanged. In other words, the first position of the coil spring is the initial position of the coil spring. Therefore, the second working area of ​​the coil spring can be regarded as a point, which corresponds to the minimum deformation amount of the coil spring in the first working area.

[0048] In another example of the above design, the switch between the folded state and the opened state can also be achieved by the coil spring in combination with the protrusion and the slide slot, and the deformation of the coil spring in these two states is different. In other words, the first position of the coil spring is different from the initial position of the coil spring. Therefore, the second working area of ​​the coil spring is a deformation area, the starting point of the deformation area is the initial position of the coil spring, the initial position corresponds to a deformation position before the minimum deformation in the first working area, and the end of the deformation area is the first position of the coil spring, and the first position corresponds to the minimum deformation position in the first working area.

[0049] In the above design, the smart glasses can achieve three states of folding, opening and expansion through the coil spring arranged outside the frame, the rotating shaft fixed to the coil spring, and the protrusion and the slide groove for limiting the rotation of the temple body. Among them, the folding state and the opening state can be achieved by the deformation of the protrusion and the slide groove or in combination with the coil spring, and the expansion state can be achieved by the deformation of the coil spring. Since the elastic force of the coil spring in the entire first working area corresponding to the expansion process is basically constant, no matter where the smart glasses are expanded, the smart glasses can provide a basically constant clamping force, so that the smart glasses can be adapted to users with various head widths and can meet the user's requirements for wearing comfort and stability. The smart glasses have good versatility.

[0050] The implementation methods of the above-mentioned designs and the beneficial effects that can be achieved will be described in detail in the embodiments section below. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0065] 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 field of vision of consumers. Compared with ordinary optical glasses, smart glasses have added optical display modules and other electronic devices to the frame, which significantly increases the weight of the frame of smart glasses. This weight increase will lead to a decrease in the user's wearing comfort, and the user will experience problems such as glasses sliding down and glasses putting a lot of pressure on the bridge of the nose during wearing. In order to solve these wearing problems, it is necessary to share the pressure through the clamping force of the temples on the user's head to enhance the stability of the whole machine.

[0066] 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 amount and deformation force of the spring are linearly related, see Figure 1b Therefore, when using this type of smart glasses, users with different head widths will usually 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 may cause unstable wearing. When worn by users with larger head widths, although they can ensure wearing stability, the clamping force provided is too large, which may cause head clamping and make the user uncomfortable. It can be seen that the temples in existing smart glasses do not fit the user's head well and are not compatible with users with different head widths.

[0067] 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 users when wearing the glasses, thereby improving the user's usage experience.

[0068] It should be noted that the smart glasses shown in this application can be used as an independent wearable device with an independent operating system. 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 the images of real environment and virtual objects in a real-time superposition manner. Of course, smart glasses can also be used as an interactive device of electronic devices, used to interact with users and send interactive information to the host of the electronic device.

[0069] Based on the above content, the following will be combined with the attached Figure 2 To Attachment Fig.11 , the smart glasses provided in this application are described in detail.

[0070] See also Figure 2 , exemplarily showing a structural diagram of a smart glasses provided by the present application. Figure 2 As shown, the smart glasses 10 include a frame 100 and temples 200, the temples 200 include temple bodies 210 and coil spring adjustment parts 220, the coil spring adjustment parts 220 include coil springs (not shown in the figure), the first end of the coil springs are connected to the frame 100, and the second end of the coil springs are connected to the temple bodies 210.

[0071] Please continue reading Figure 2 , the smart glasses 10 may further include a lens 300, which is mounted on the frame 100. The figure shows that the lens 300 is mounted below the frame 100, 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 also be surrounded by the frame 100 in the center. In some examples, the lens 300 may be a lens for correcting vision, 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 users to watch 3D images or virtual images, such as a display screen, which may present images such as game screens, movie screens, or navigation maps to the user.

[0072] The above-mentioned frame 100 may also be referred to as a middle frame or a frame. In some scenarios, the frame 100 has a closed space, which can be used to place some electronic devices related to the functions of the smart glasses 10, such as cameras and sensors, and can also be used to place optical devices related to imaging, such as light sources, projectors, and optical lenses. Of course, it can also be used to set circuit routing.

[0073] It can be understood that one end of the temple body 210 is connected to the frame 100 through the coil spring adjustment part 220 to form the mechanical main structure of the smart glasses 10. When the smart glasses 10 are worn, the temple body 210 is placed on the human ear so that the lens 300 installed on the frame 100 is located in front of the human eye. Optionally, the temple body 210 may also have a closed space, which is used to place other electronic devices related to the functions of the smart glasses 10, such as circuit boards, batteries, speakers, microphones, etc.

[0074] The coil spring adjusting portion 220 includes a coil spring and may also include other components. Figure 3a , is a schematic diagram of a coil spring structure in this application. Among them, Figure 3a (A) shows a three-dimensional structure diagram of a coil spring. Figure 3a (B) shows a cross-sectional view of a coil spring. Figure 3a As shown, coil springs are generally made of stainless steel strips or other relatively wide elastic materials, usually including 3 or more coils, and the figure shows 3 coils as an example. The end of the coil spring located in 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 a fixed end, and the other end is a free end. The fixed end is relatively stationary with respect to the surrounding structural parts. When the coil spring is stretched, the free end is displaced relative to the fixed end, so that the coil spring is wound tightly, the diameter of the coil spring becomes smaller, and the coil spring generates a certain elastic force. When the coil spring rebounds, the free end is displaced relative to the fixed end, so that the coil spring is relaxed, the diameter of the coil spring becomes larger, and the elastic force of the coil spring becomes smaller.

[0075] Furthermore, a coil spring is an elastic mechanism that can generate a stable elastic force. For example, see Figure 3b , is a spring characteristic curve diagram of the coil spring in the present application, wherein the horizontal axis is the deformation of the coil spring and the vertical axis is the spring force generated by the coil spring. Figure 3b As shown, within a small deformation range at the beginning of deformation, the elastic force generated by the coil spring will increase rapidly as the deformation increases (called the rapid growth period). When the deformation reaches a certain value (called the mutation state point, such as state point a in the figure), as the deformation continues to increase, the elastic force generated by the coil spring basically tends to be constant (called the stable period).

[0076] Based on the above 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 a deformation range in the stable period. For example, the initial state of the coil spring during the expansion of the temple body 210 can be configured to be a state point just after crossing the sudden change state point a, such as the state point b shown in the figure, and the maximum deformation state of the coil spring during the expansion of the temple body 210 can be configured to be a state point located after the state point b, such as the 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, which is usually not more than 30°, please refer to the following for details). Figure 5 ), the deformation of the coil spring is within the deformation region between state point b and state point c shown in the figure. This deformation region is called the working region of the coil spring in the outward expansion state (referred to as the first working region). The length change of the coil spring in the first working region is much smaller than the overall length of the coil spring. In this way, during the process of the smart glasses 10 from the open state to being worn on 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.

[0077] Further illustratively, in order to ensure that the clamping force provided by the smart glasses 10 meets the wearing comfort and stability of the user, the 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.

[0078] In addition, it should be noted that the temple body 210 has other states besides the outward expansion state, such as a folded state or an open state (for details, please refer to the following Figure 5), the present application only limits the first working area of ​​the coil spring when the temple body 210 is in the expanded state, and does not limit the second working area of ​​the coil spring when the temple body 210 is in the non-expanded state. For example, the second working area of ​​the coil spring can be configured as a point, that is, during the entire process from folding to opening of the temple body 210, the deformation of the coil spring remains unchanged, and the deformation can be configured as the minimum deformation in the first working area for example. Alternatively, the second working area of ​​the coil spring can also be configured to include a certain deformation area during the rapid rise period, in which case, the elastic force provided by the coil spring during the non-expanding process is different from the elastic force provided during the expanding process. Alternatively, the second working area of ​​the coil spring can also be configured as the area between the rapid rise period and the first working area, in which case, the elastic force provided by the coil spring during the non-expanding process is substantially the same as the elastic force provided during the expanding process. And so on.

[0079] Based on the above introduction, the specific structure of the smart glasses is described in detail below. It can be understood that the temple 200 generally includes two temples, so the temple body 210 and the spring adjustment part 220 also include two temples. The following description takes one spring adjustment part 220 connecting one temple body 210 and the frame 100 as an example.

[0080] Implementation plan 1

[0081] See also Figure 4 , exemplarily showing a partial structural diagram of the smart glasses in the implementation scheme 1. Figure 4 (A) shows the local structure of the smart glasses seen from the temples after removing the innermost layer of the frame 100 (i.e., the side close to the user's eyes). Figure 4 (B) shows a cut along the center of the frame parallel to the lens. Figure 4 The cross-sectional structure obtained in the part shown in (A) is shown below. Figure 4 Middle (A) and Figure 4 In (B), components that may be included in the smart glasses 10 are introduced in detail.

[0082] First, see Figure 4In (B), the coil spring adjustment portion 220 may include a coil spring 221 and a support portion 222, wherein 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 end F 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 end F of the coil spring may be considered as a free end, and when the end F of the coil spring rotates relative to its fixed end (end D in the figure), the support portion 222 fixedly connected to the end F of the coil spring is synchronously driven to rotate, thereby driving the temple body 210 connected to the end E2 of the support portion 222 to rotate, so as to achieve the outward expansion of the temple body 210 relative to the frame 100.

[0083] For an example, see Figure 4 Middle (A) or Figure 4 In (B), the frame 100 may also have a limiting component H, which is used to limit the rotation range of the support portion 222. It should be noted that the figure takes the limiting component H as a limiting hole as an example, the support portion 222 passes through the limiting hole H, one end of which is connected to the F end of the coil spring 221, and the other end is connected to the temple body 210, so that the support portion 222 can be limited to rotate between the two edges of the limiting hole H, thereby driving the temple body 210 to expand inward and outward in a small area relative to the frame 100. When the temple body 210 expands in this area, the deformation area of ​​the coil spring 221 corresponds to the first working area of ​​the coil spring 221. It should be understood that the limiting component can also be other components or components that can realize the limiting function, such as a limiting hole, a limiting slide groove, a spiral limiting mechanism, a pin limiting mechanism, a spring limiting mechanism, a hydraulic limiter, a photoelectric limiter, etc., which are not specifically limited.

[0084] For an example, see Figure 4 In (A), the coil spring adjustment portion 220 may 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 achieving the folding or opening of the temple body 210 relative to the frame 100.

[0085] It is understandable that the folding adjustment portion 223 may be any component or assembly capable of realizing the folding function. For example, it may be a folding hinge. Figure 4In (B), the folding adjustment part 223 may include a rotating shaft 2231, and the E2 end of the support part 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 part 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, so that the temple body 210 is folded below the frame 100 shown in the figure. 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 in the figure, 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.

[0086] For an example, please refer to Figure 4 Middle (A) and Figure 4 In (B), the first end (D end in the figure) of the coil spring can be fixed on the frame 100, and specifically, can be 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, and the fixing method can be welding, pasting, riveting, threading, etc.

[0087] Optionally, for a specific fixing method, please continue to refer to Figure 4 In (B), the frame 110 has a fixed shaft 120, and a first slot is provided on the fixed shaft 120. The D end of the coil spring 221 is embedded in the first slot so that it is clamped by the first slot and fixed in the frame 110. The 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.

[0088] For further examples, see Figure 4 In (B), the E1 end of the support portion 222 may also have a hollow accommodating cavity, in which the coil spring 221 and the fixed shaft 120 are embedded, so as to prevent dust and other impurities from entering the cavity to corrode the coil spring 221 and affect the performance of the coil spring 221.

[0089] Optionally, to ensure the integrity of the containment cavity structure, refer to Figure 4 In (A), the frame body 110 may further include a cover plate 130 , which covers the accommodating cavity to wrap the coil spring 221 and the fixed shaft 120 inside.

[0090] In addition, in order to maintain the stability of the cover plate 130 on the receiving cavity and prevent it from moving, the cover plate 130 can also be fixedly connected to the frame body 110. For example, please continue to refer to Figure 4 In (A), the frame 110 has at least one support column, and the at least one support column is screwed together with the cover plate 130 by screws, so that the cover plate 130 is fixed to the frame 110. It should be understood that Figure 4 The following description takes the example of two support columns 141 and 142 threadedly fixing the cover plate as an example, but in practice one or more support columns may be provided, and the support columns and the cover plate may also be fixed by other means, which are not specifically limited.

[0091] 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 a specific fixing method, please continue to refer to Figure 4 In (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 embedded in the first opening to be engaged with the outer shell of the accommodating cavity.

[0092] The above content introduces the possible structure of the smart glasses 10. The possible states of the smart glasses 10 will be described below.

[0093] The smart glasses in the first implementation can be realized in three states: folded state, open state and expanded state. Figure 5 As shown. Further, Figure 6 A partial cross-sectional structure diagram of the smart glasses in each state is shown, for example, Figure 6 (A) shows the local cross-sectional structure of the smart glasses in the folded state. Figure 6 (B) shows a partial cross-sectional structure diagram of the smart glasses when they are in the open state. Figure 6 (C) shows a partial cross-sectional structure diagram of the smart glasses in the expanded state.

[0094] First, see Figure 6 In (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.

[0095] Second, see Figure 6 In (B), when the support portion 222 is located at the first edge H1 of the limiting component and the folding adjustment portion 223 is in the open state, the smart glasses 10 are in the open state. Figure 6In the folded state shown in (A), the temple body 210 is pushed in the clockwise direction as shown in the figure, so that it rotates around the support portion 222 from the upper limit groove of the E2 end of the support portion 222 at the edge I1 shown in the figure to the edge I2 shown in the figure, and the temple body 210 is unfolded, 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 outward expansion position.

[0096] It should be noted that according to Figure 6 Middle (A) and Figure 6 In the position limiting method shown in (B), the temple body 210 is rotated from the folded state to the open state or from the open state to the folded state. This process is completely realized by the folding adjustment part 223, and the coil spring 221 is not involved. In this case, during the process of the temple body 210 rotating from the folded state to the open state, the support part 222 is always located at the first edge H1 of the limiting component, and the support part 222 does not rotate. Therefore, the deformation amount of the coil spring 221 remains unchanged, and the second working area of ​​the coil spring 221 remains as a point, which corresponds to the minimum deformation amount in the first working area of ​​the coil spring, that is, Figure 3b The deformation corresponding to the state point b is shown.

[0097] Understandably, Figure 6 Middle (A) and Figure 6 The state switching method shown in (B) is only one possible example. In another example, the coil spring 221 and the folding adjustment part 223 can also be used together to realize the switching between the folded state and the open state. For example, in the process of using the folding adjustment part 223 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 part 222 is located at a certain position between the first edge H1 and the second edge H2 of the limiting component, and the folding adjustment part 223 is in the open state. In this case, since the coil spring 221 will also have a small deformation in the process of opening the smart glasses 10, the second working area of ​​the coil spring 221 remains as a deformation area, and the starting point of the deformation area corresponds to Figure 3b The deformation amount before the deformation amount corresponding to the state point b shown in the figure, the end of the deformation amount area corresponds to Figure 3b The deformation amount corresponding to the state point b shown, when the deformation amount 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 outward expansion process, and when the deformation amount 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 outward expansion process.

[0098] Furthermore, please see Figure 6In (C), when the support portion 222 is located at the second edge H2 of the limiting component or a certain position between the first edge H1 and the second edge H2 (the figure shows that the support portion 222 is 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. Figure 6 In the open state shown in (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 to the temple body 210 will cause the temple body 210 to continue to rotate in the clockwise direction shown in the figure during the process of wearing the smart glasses 10 on the user's head. However, at this time, the temple body 210 is already at the edge I2 of the limit groove shown in the figure, and the temple body 210 can no longer rotate along the support part 222. Therefore, the temple body 210 will drive the support part 222 to rotate clockwise, and then drive the F end of the coil spring 221 fixed on the E1 end of the support part 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.

[0099] In addition, as the outward expansion angle increases, the clamping force generated by the coil spring 221 also increases, but as mentioned above Figure 3b In the introduction of the first working area, at 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 Figure 3b The deformation amount corresponding to the state point b shown in the figure) to 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 Figure 3b The elastic force generated by the coil spring 221 is substantially constant, so that the clamping force of the smart glasses 10 on the head is substantially constant. In this way, when users with different head widths wear the smart glasses 10, they can get the same clamping force experience, and users with larger head widths will not have their heads clamped, and users with smaller head widths will not feel unstable when wearing the glasses, which helps to improve wearing comfort and wearing stability at the same time.

[0100] By adopting the smart glasses structure in the above-mentioned implementation scheme 1, the three states of folding, opening and expansion can be realized by means of the coil spring arranged inside the frame and the folding adjustment part arranged outside the frame. When the user is not wearing the smart glasses, the smart glasses can be folded and stored by the folding adjustment part. When the user wears the smart glasses, the smart glasses can be opened by the folding adjustment part, and the temples can be expanded outwards to match the head width by the coil spring. Moreover, in the expanded state, no matter where the smart glasses are expanded outwards, the smart glasses can provide a basically constant clamping force, so that the smart glasses can be adapted to users of various head widths, meet the user's needs for wearing comfort and stability, and the smart glasses have good versatility.

[0101] Implementation Plan 2

[0102] Compared with the structure of the smart glasses in the above-mentioned implementation scheme 1, the implementation scheme 2 simplifies the smart glasses, cancels the folding adjustment part in the implementation scheme 1, retains only the coil spring related components, and places the coil spring externally, so that the folded state and the expanded state of the smart glasses are both provided by the coil spring. The specific structure of the smart glasses in the implementation scheme 2 is described in detail below.

[0103] See also Figure 7 , exemplarily showing a partial structural diagram of the smart glasses in the second implementation scheme. Figure 7 (A) shows the local structure of the smart glasses seen from the temples after removing the innermost layer of the frame 100 (i.e., the side close to the user's eyes). Figure 7 (B) shows a cut along the center of the frame parallel to the lens. Figure 7 The cross-sectional structure obtained in the part shown in (A) is shown below. Figure 7 Middle (A) and Figure 7 In (B), components that may be included in the smart glasses 10 are introduced in detail.

[0104] First, see Figure 7 In (B), the coil spring adjustment part 220 may include a coil spring 221 and a support part 222, wherein the support part 222 is connected between the frame 100 and the first end (D end in the figure) of the coil spring 221, and is used to support the coil spring 221 outside the frame 100. The D end of the coil spring 221 can be considered as a fixed end, and the free end (F end in the figure) of the coil spring 221 is connected to the temple body 210. When the F end of the coil spring 221 rotates relative to the D end, the temple body 210 connected to the F end of the coil spring 221 will be synchronously driven to rotate, so as to realize the rotation of the temple body 210 relative to the frame 100.

[0105] For an example, see Figure 7In (B), 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.

[0106] Understandably, Figure 7 In the example, the E1 end of the support portion 222 is fixed to the frame 100 by bolts, but the actual smart glasses 10 can also be fixed by any one or more of welding, rivets, magnetism, bonding, clamping, hanging, locking, riveting or snapping, etc., without specific limitation.

[0107] In a further example, the E2 end of the support portion 222 can also be fixedly connected to the D end of the coil spring 221 by any of the aforementioned fixing methods. Figure 7 In (B), the E2 end of the support part 222 has a fixed shaft 231, and a first slot is provided on the fixed shaft 231. The D end of the coil spring 221 is embedded in the first slot, so that it is clamped by the first slot and fixed on the E2 end of the support part 222. Fixing by slotting and clamping is convenient to prepare, and no additional fixing parts are required, which helps to reduce costs and structural complexity.

[0108] For further examples, see Figure 7 In (B), the E2 end of the support portion 222 may also have a hollow accommodating cavity, in which the coil spring 221 and the fixed shaft 231 are embedded, 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.

[0109] Optionally, to ensure the integrity of the containment cavity structure, refer to Figure 7 In (A), the accommodating cavity can also be sealed by the outer shell on the temple body 210 and the outer shell of the supporting part 222 to wrap the coil spring 221 and the fixed shaft 231 inside.

[0110] In one example, the E2 end of the support portion 222 may also have 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 may 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.

[0111] In further examples, taking the limiting component as a limiting hole as an example, please continue to refer to Figure 7In (B), the E2 end of the support portion 222 has a limiting hole K (the limiting hole K is provided on the housing of the accommodating cavity as an example in the figure), and the temple body 210 passes through the limiting hole K and is fixedly connected to the F end of the coil spring 221. In this way, the temple body 210 can be limited to rotate between the two edges of the limiting hole K.

[0112] The above content introduces the possible structure of the smart glasses 10. The possible states of the smart glasses 10 will be described below.

[0113] The smart glasses in the second implementation scheme can be realized in two states: folded state and expanded state, such as Figure 8 As shown. Further, Fig. 9 A partial cross-sectional structure diagram of the smart glasses in each state is shown, for example, Fig. 9 (A) shows the local cross-sectional structure of the smart glasses in the folded state. Fig. 9 (B) shows a partial cross-sectional structure diagram of the smart glasses in the expanded state.

[0114] First, see Fig. 9 In (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 has no deformation or has a small deformation.

[0115] Second, see Fig. 9 In (B), when the temple body 210 is located at the second edge H2 of the limiting hole or a certain position between the first edge H1 and the second edge H2 (the figure shows that the temple body 210 is located at the second edge H2 of the limiting hole), the smart glasses 10 are in the outward expansion state. Fig. 9 When the folded state shown in (A) is worn on the user's head, the temple body 210 will rotate in the limiting hole in the clockwise direction as shown in the figure, thereby driving the F end of the coil spring 221 fixed thereto to rotate together, until the temple body 210 is clamped on both sides of the user's head. 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 wound up, 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. In addition, after the user has finished wearing the glasses and takes off the smart glasses 10, the temple body 210 will automatically rebound to the position under the action of the elastic force of the coil spring. Fig. 9 The folded state shown in (A).

[0116] It should be noted that the wearing process of the smart glasses 10 in the second implementation scheme may include two stages:

[0117] In stage one, the user places the temple body 210 Fig. 9The temple body 210 is opened in the folded state shown in (A). During this process, the temple body 210 rotates clockwise in the limit hole under the action of the user's manual force. Fig. 9 The position H3 of the limiting hole shown in (B) can be designed according to the head width of the customer group of the smart glasses 10, for example, it can be configured as the position of the temple body 210 after the user with the smallest head width wears the smart glasses 10.

[0118] 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 the position H3 under the action of the head resistance, or continue to rotate clockwise until it rotates to a position that matches the width of the user's head.

[0119] The above-mentioned stage 2 corresponds to the first working area of ​​the coil spring 221. The first working area can refer to the above-mentioned Figure 3b For example, the deformation amount of the coil spring 221 when the temple body 210 is at the minimum outward expansion position H3 is Figure 3b The deformation corresponding to the state point b shown in FIG. 1 and the deformation when the temple body 210 is at the maximum outward expansion position H2 are: Figure 3b Thus, for users with different head widths, although the temple body 210 finally stops at different positions, the rotation range of the temple body 210 between the minimum outward expansion position H3 and the maximum outward expansion position H2 is pre-designed to correspond exactly to the rotation range of the coil spring 221 at the minimum outward expansion position H3 and the maximum outward expansion position H2. Figure 3b The deformation range between the state point b and the state point c shown can make the elastic force generated by the coil spring 221 during the rotation of the temple body 210 basically constant, so that the clamping force of the smart glasses 10 on the heads of users with different head widths is basically constant.

[0120] In addition, the above stage 1 corresponds to the second working area of ​​the coil spring 221, and the second working area can be configured in a variety of situations, such as:

[0121] In one possible design, the second working area can be configured as Figure 3b The region between the mutation state point a or a state point after it to the state point b shown in the figure, in this case, the second working region is in a stable period, and in the process of the temple body 210 switching from the folded state to the opened state, although the deformation amount of the coil spring 221 changes, the elastic force provided by the coil spring 221 remains substantially unchanged, and the elastic force is approximately equal to the elastic force provided by the coil spring 221 in the outward expansion state;

[0122] In another possible design, the second working area can be configured as Figure 3bThe area between a state point before the sudden change state point a and state point b is shown. In this case, the second working area spans from the rapid growth period to the stable period. In the process of the temple body 210 switching from the folded state to the opened state, the deformation amount 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 area to the constant elastic force corresponding to the first working area. For example, assuming that the second working area is configured to change from no deformation or slight deformation to Figure 3b The deformation amount corresponding to the state point b shown in the figure is within a range. In the process of the temple body 210 switching from the folded state to the opened state, the elastic force provided by the coil spring 221 gradually increases from 0 to a constant elastic force corresponding to the first working area.

[0123] By adopting the smart glasses structure in the second implementation scheme, the two states of folding and expanding can be realized by means of the coil spring and the limiter components arranged outside the frame. Moreover, in the expanded state, no matter where the smart glasses are expanded, the smart glasses can provide a substantially constant clamping force, so that the smart glasses can be adapted to users with various head widths and can meet the users' requirements for wearing comfort and stability, and the smart glasses have good versatility.

[0124] Implementation plan three

[0125] Compared with the structure of the smart glasses in the above-mentioned implementation scheme 2, the implementation scheme 3 adds a rotating part that can realize the open state in the smart glasses, and makes it cooperate with one end of the coil spring to fix each other, and at the same time, a special shape of groove is opened on the part that cooperates with the rotating part, so that the smart glasses can realize the three states of folding, opening and expanding. The specific structure of the smart glasses in the implementation scheme 3 is introduced in detail below.

[0126] See also Fig.10 , exemplarily showing a partial structural diagram of the smart glasses in the third implementation scheme. Fig.10 (A) shows the local structure of the smart glasses seen from the temples after removing the innermost layer of the frame 100 (i.e., the side close to the user's eyes). Fig.10 (B) shows a cut along the center of the frame parallel to the lens. Fig.10 The cross-sectional structure obtained in the part shown in (A) is shown below. Fig.10 Middle (A) and Fig.10 In (B), components that may be included in the smart glasses 10 are introduced in detail.

[0127] First, see Fig.10In (B), the coil spring adjustment part 220 may include a coil spring 221 and a support part 222, wherein the support part 222 is connected between the frame 100 and the first end (end F in the figure) of the coil spring 221. For example, the frame 100 has a first opening H, the support part 222 passes through the first opening H, the first end (end E1 in the figure) is fixed to the frame 100, and the second end (end E2 in the figure) is fixed to the end F of the coil spring 221, so as to support the coil spring 221 outside the frame 100.

[0128] It should be noted that Fig.10 In the example, the E1 end of the support part 222 is fixed to the frame 100 by screws, and the F end of the coil spring 221 is 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 fix the F end of the coil spring 221 to the E2 end of the support part 222, etc., without specific limitation.

[0129] For an example, please refer to Fig.10 Middle (A) and Fig.10 In (B), the coil spring adjustment part 220 may further include a rotating part 223, the rotating part 223 includes a rotating shaft 2231, and the E2 end of the support part 222 and the temple body 210 are respectively sleeved on the rotating shaft 2231. With this design, the temple body 210 can rotate relative to the support part 222 around the rotating shaft 2231, thereby realizing the rotation of the temple body 210 relative to the frame 100.

[0130] 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 piece and is not fixed to the frame 100 or the support portion 222 , and the rotating shaft 2231 itself can also rotate.

[0131] In a further example, the rotating portion 223 may also have a limiting component, which is used to limit 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.

[0132] For a specific design of the limit component, please refer to Fig.10 Middle (A) and Fig.10In (B), the rotating shaft 2231 has a protrusion 2232, the temple body 210 includes a cover plate 211, the cover plate 211 is provided with a slide groove 212, the rotating shaft 2231 is covered by the cover plate 211, and the protrusion 2232 is embedded in the slide groove 212. In this way, as the temple body 210 rotates, the slide groove 212 on the temple body 210 can be blocked at the edge by the protrusion 2232, thereby limiting the temple body 210 from rotating between the two edges of the slide groove 212 being blocked, and the rotation range corresponds to the state between the folded state and the open state of the smart glasses 10. For example, when the right edge of the slide groove 212 shown in the figure is stuck by the protrusion 2232, the temple body 210 is folded below the frame 100, and the smart glasses 10 are in a folded state. When the temple body 210 rotates clockwise 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 stuck by the protrusion 2232, the temple body 210 unfolds and the smart glasses 10 are in the open state. It can be understood that in the process of the smart glasses 10 from the folded state to the open state, the position of the protrusion 2232 can always remain unchanged, and the smart glasses 10 are switched between the two states by sliding the slide groove 212 along the protrusion 2232.

[0133] In a further example, in order to enable the smart glasses 110 to have an expanded state, please continue to refer to Fig.10 In (B), the D end of the coil spring 221 is fixed on the rotating shaft 2231. The D end of the coil spring can be considered as a free end. In this way, when the temple body 210 rotates clockwise as shown in the figure, even if the slide groove 212 on the temple body 210 is stuck on the upper edge of the figure by the protrusion 2232, causing the temple body 210 to be unable to rotate further around the rotating shaft 2231, since the rotating shaft 2231 is a suspended shaft, the temple body 210 can drive the stuck protrusion 2232 to rotate clockwise, and then drive the rotating shaft 2231 where the protrusion 2232 is located to rotate, and then drive the D end of the coil spring 221 fixed to the rotating shaft 2231 to rotate, and 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.

[0134] In a further example, the D end of the coil spring 221 can be fixed to the rotating shaft 2231 by any one or more of welding, pasting, rivet, magnetism, clamping, hanging, locking, riveting or buckling. For example, in a specific fixing method, please continue to refer to Fig.10 In (B), a first groove is formed on the rotating shaft 2231, and the D end of the coil spring 221 is inserted into the first groove so that the coil spring 221 is clamped by the first groove and fixed on the rotating shaft 2231. The fixing by the slotted clamping method is convenient to prepare and does not require the introduction of additional fixing parts, which helps to reduce costs and structural complexity.

[0135] For further examples, see Fig.10 In (B), the E2 end of the support portion 222 may also have a hollow accommodating cavity, in which the coil spring 221 and the rotating shaft 2231 are embedded, 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.

[0136] Optionally, to ensure the integrity of the containment cavity structure, refer to Fig.10 In (A), the accommodating cavity can also be sealed by the outer shell on the temple body 210 and the outer shell of the supporting part 222 to wrap the coil spring 221 and the rotating shaft 2231 inside.

[0137] The above content introduces the possible structure of the smart glasses 10. The possible states of the smart glasses 10 will be described below.

[0138] The smart glasses in the third implementation scheme can realize three states: folded state, open state and expanded state, as mentioned above Figure 5 As shown. Further, Fig.11 A partial cross-sectional structure diagram of the smart glasses in each state is shown, for example, Fig.11 (A) shows the local cross-sectional structure of the smart glasses in the folded state. Fig.11 (B) shows a partial cross-sectional structure diagram of the smart glasses when they are in the open state. Fig.11 (C) shows a partial cross-sectional structure diagram of the smart glasses in the expanded state.

[0139] First, see Fig.11 In (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.

[0140] Secondly, please refer to Fig.10 and Fig.11 In (B), when the protrusion 2232 is located at the second edge H2 of the slide groove 212 and the coil spring 221 is located at the first position, the smart glasses 10 are in the open state. Optionally, the first position may refer to the initial position of the coil spring 221. In this case, the smart glasses 10 are switched from the folded state to the open state or from the switched state to the folded state. This process can be completely realized by the protrusion 2232 and the slide groove 212, and the coil spring 221 is not involved, so that the initial position of the coil spring 221 can be Figure 3b For example, when the smart glasses 10 are moved from Fig.11During the process of opening the folded state shown in (A), the temple body 210 rotates in the clockwise direction as shown, driving the slide groove 212 on the temple body 210 to rotate in the clockwise direction as shown, and when the second edge H2 of the slide groove 212 is stuck by the protrusion 2232, the temple body 210 unfolds and the smart glasses 10 switches to the open state. In this way, during the process of the smart glasses 10 switching from the folded state to the open state, the position of the protrusion 2232 does not change, so the position of the shaft 2231 where the protrusion 2232 is located does not change. Compared with the folded state, the shaft 2231 in the open state does not rotate, so the D end of the coil spring 221 fixed to the shaft 2231 does not rotate, and the coil spring 221 does not deform, and the coil spring remains in the open state. Figure 3b The deformation corresponding to the state point b is shown. Fig.11 The open state shown in (B) is Fig.11 When the folding state shown in (A) changes, the temple body 210 rotates counterclockwise as shown in the figure. Due to the deformation resistance of the coil spring 221 itself, the shaft 2231 and the protrusion 2232 arranged thereon are almost immobile relative to the smart glasses 10. The temple body 210 rotates relatively with the shaft 2231, and the slide groove 212 on the temple body 210 slides counterclockwise along the protrusion 2232 on the shaft 2231 until the first edge H1 of the slide groove 212 is caught by the protrusion 2232. In this process, the coil spring 221 has no obvious deformation and always remains in Figure 3b The deformation corresponding to the state point b is shown.

[0141] It can be 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 are switched from the folded state to the opened state or from the switched state to the folded state. This process is achieved by the coil spring 221 in conjunction with the protrusion 2232 and the slide groove 212, so that the initial position of the coil spring 221 can be located at Figure 3b The first position of the coil spring 221 may be a position before the deformation amount corresponding to the state point b shown in FIG. Figure 3bSpecifically, in the process of unfolding the temple body 210 by using the protrusion 2232 and the slide 212, the deformation of the coil spring 221 can be synchronously used to drive the rotation shaft 2231 to rotate and then drive the temple body 210 to further unfold, so that 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 of the initial position and the deformation of the first position. When the deformation area is in a stable period, the elastic force provided by the coil spring 221 is substantially 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 is different from the elastic force provided during the expansion process.

[0142] Furthermore, please refer to Fig.10 and Fig.11 In (C), when the protrusion 2232 is located at the second edge H2 of the slide slot and the coil spring 221 is located at the second position, the smart glasses 10 are in the outward expansion state. The second position refers to a position where the diameter of the coil spring 221 is smaller than that at the first position, or in other words, a position where the elastic force generated by the coil spring 221 is greater than that at the first position, for example, it may be a position at the end or in the middle of the first working area of ​​the coil spring 221, that is, Figure 3b The position of the deformation amount corresponding to the state point c shown, or the position of a certain deformation amount between the state point b and the state point c. For example, when the smart glasses 10 are moved from Fig.11 During the process of wearing the temple body 210 on the head in the open state shown in (B), the temple body 210 continues to rotate in the clockwise direction as shown in the figure under the action of the head resistance force. Since the temple body 210 is stuck by the protrusion 2232, the temple body 210 and the protrusion 2232 form a hard contact, and the temple body 210 will drive the protrusion 2232 to rotate clockwise, and then drive the rotating shaft 2231 where the protrusion 2232 is located to rotate clockwise. The rotation of the rotating shaft 2231 will also The D end of the coil spring 221 fixed on the rotating shaft 2231 will be driven 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 up, 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 winding trend, the coil spring 221 itself will generate an opposite elastic force, that is, a clamping force. The clamping force of the coil spring 221 causes the temple body 210 to be clamped on both sides of the user's head. In addition, since the elastic force generated by the coil spring 221 in the first working area is pre-designed to be basically constant, when the smart glasses 10 are expanded to different positions, the clamping force on the head is also basically constant.

[0143] By adopting the smart glasses structure in the third implementation scheme, the three states of folding, opening and expanding can be realized through the coil spring arranged outside the frame, the suspended shaft and the protrusion arranged on the shaft. Moreover, in the expanded state, no matter where the smart glasses are expanded, the smart glasses can provide a basically constant clamping force, so that the smart glasses can be adapted to users with various head widths and meet the users' requirements for wearing comfort and stability, and the smart glasses have good versatility.
