     TECHNICAL FIELD 
     The present application relates to the technical field of electronic products, and in particular, to a glass frame structure and a wearable device. 
     BACKGROUND 
     With the development of electronic devices, there are more and more types of electronic devices, and there are also more and more types of wearable devices such as smart glasses and smart bracelets. For example, smart glasses have changed from the initial monocular form to head-mounted glasses, traditional glasses, etc. Users can enjoy the application experience by wearing smart glasses, so that more and more smart glasses products are favored by a wide range of users. However, for users who need to wear ordinary glasses on a daily basis, such as myopia glasses, if the user wears smart glasses after taking off the myopia glasses, the viewing experience of the smart glasses will be affected. If the smart glasses are worn directly without taking off the myopia glasses, because myopia glasses need to be accommodated between human eyes and the lens of the smart glasses, it is inconvenient to wear smart glasses due to the limited distance between the forehead and the smart glasses. In addition, the size of the nose support pad set on the glass frame in the current smart glasses is generally fixed. Due to the differences in the face shapes and nose shapes of different users, this type of smart glasses cannot be worn by different users.

On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art. 
     As shown in  FIG.  1   , embodiments of the present application provide a glass frame structure, including: a nose pad  1 , a limiting member  5 , and a glass frame body  3 . 
     The nose pad  1  is provided with one of a hook structure or a slot structure; the glass frame body  3  is provided with the other one of the hook structure or the slot structure. 
     The limiting member  5  is located at a first position or a second position, wherein when the limiting member  5  is located at the first position, the limiting member  5  avoids the hook structure, and the hook structure is located in the slot structure and can move within the slot structure; and when the limiting member is at the second position, the limiting member abuts against the hook structure and the hook structure is locked in the slot structure. 
     In some embodiments, the glass frame structure may further include: a glass frame front shell  4 , and the glass frame front shell  4  is connected to the glass frame body  3 . 
     In some embodiments, the glass frame body  3  may include: a mounting frame  31 , a first glass leg  32 , and a second glass leg  33 ; wherein the first glass leg  32  is connected to a first end of the mounting frame  31 , and the second glass leg  33  is connected to a second end of the mounting frame  31 , and the first glass leg  32  and the second glass leg  33  are used to be worn on the ears. 
     In some embodiments, the nose pad  1  and the glass frame body  3  are connected through a hook structure and a slot structure, to ensure that the nose pad  1  is detachable relative to the glass frame body  3  and the nose pad  1  can be replaced, so that the same glass frame body  3  can be compatible with different types of nose pads  1  and can be applied for different users to wear. In a case that the nose pad  1  is installed on the glass frame body  3 , the movement of the nose pad  1  relative to the glass frame body  3  can also be restricted by the limiting member  5 . While the nose pad  1  is detachable relative to the glass frame body  3 , installation reliability between the nose pad  1  and the glass frame body  3  is also ensured. 
     In some embodiments, the nose pad  1  can be provided with the hook structure and the glass frame body  3  can be provided with the slot structure, or the nose pad  1  can be provided with the slot structure and the glass frame body  3  can be provided with the slot structure, or the nose pad  1  and the glass frame body  3  can be detachable from each other through a cooperation structure of a chute and a slider. The embodiments of the present application are not limited thereto. 
     In the following, for example, the nose pad  1  is provided with the hook structure and the glass frame body  3  is provided with the slot structure: 
     The hook structure includes: a fixing plate  20  and a first hook body  21 . A first surface of the fixing plate  20  is connected to the nose pad  1 ; and the first hook body  21  is provided on a second surface of the fixing plate  20 ; where the first surface and the second surface are provided opposite to each other. 
     The slot structure includes: a first through hole  302  opened on a first mounting plate  301  of the glass frame body  3 . 
     When the limiting member  5  is located at the first position, the limiting member  5  avoids the fixing plate  20  and the first hook body  21  is located in the first through hole  302  and can move in the first through hole  302 ; and when the limiting member  5  is at the second position, the limiting member  5  abuts against the fixing plate  20  and the first hook body  21  is locked in the first through hole  302 . 
     In some embodiments, the mounting frame  31  includes the first mounting plate  301 , and the first mounting plate  301  is used to install the nose pad  1 , and the nose pad  1  is used to be worn on the nose. 
     In the embodiments, the nose pad  1  and the glass frame body  3  are connected through cooperation of the first hook body  21  and the first through hole  302 , to ensure that the nose pad  1  is detachable relative to the glass frame body  3  and the nose pad  1  can be replaced, so that the same glass frame body  3  can be compatible with different types of nose pads  1  and can be applied for different users to wear. Moreover, through the cooperative connection between the first hook body  21  and the first through hole  302 , less space is occupied, which can avoid excessive increase in the volume of the glass frame structure. 
     As shown in  FIG.  2   , the first hook body  21  may be in the shape of a “mushroom head”, and the first hook body  21  may include: a first hook portion  211  and a connecting column  212 . 
     The nose pad  1  is arranged on the first surface of the fixed plate  20 , the first end of the connecting column  212  is connected with the second surface of the fixed plate  20 , and the first hook portion  211  is connected with the second end of the connecting column  212 . The first hook portion  211  passes through the first through hole  302  along a direction from a first surface of the first mounting plate  301  to a second surface of the first mounting plate  301 , and is fastened on the second surface of the first mounting plate  301 . The first surface and the second surface are opposite to each other. 
     In this way, the first hook body  21  in the shape of a “mushroom head” can be locked on the second surface of the first mounting plate  301  through the first hook portion  211 , so as to limit the left and right rotation of the nose pad  1  and limit the fall out of the nose pad  1  in the vertical direction (that is, the direction from the first surface to the second surface). 
     It should be noted that  FIG.  2    shows an example in which the glass frame structure is provided with two first hook bodies  21  and a first through hole  302 . Of course, in the embodiments of the present application, the numbers of the first hook bodies  21  and the first through holes  302  are not limited thereto. 
     In this embodiment, the first hook portion  211  and the nose pad  1  are arranged on opposite surfaces of the fixing plate  20  respectively, so that the first hook portion  211  can pass through the first surface and the second surface of the first mounting plate  301  and clamped on the second surface, to realize the clamping between the nose pad  1  and the glass frame body  3 . Besides, the structure is simple and easy to disassemble and install, and through the clamping between the nose pad  1  and the glass frame body  3 , the detachable connection between the nose pad  1  and the glass frame body  3  can be implemented without increasing the volume, so as to ensure that the same frame body  3  can be compatible with different types of nose pads, and can be worn by different users. 
     As shown in  FIG.  2    and  FIG.  3   , the first through hole  302  includes a first portion and a second portion. 
     A first size of the first portion along the first direction is larger than a second size of the second portion along the first direction, a third size of the first hook portion  211  along the first direction is larger than the second size, and a fourth size of the connecting column  212  along the first direction is smaller than the second size; 
     wherein after the first hook portion  211  passes through the first portion along the direction from the first surface of the first mounting plate  301  to the second surface of the first mounting plate, the first hook portion moves to the second portion and is fastened on the second surface. 
     In this embodiment, the first portion of the first through hole  302  fits the first hook portion  211 , so that the first hook portion  211  can be vertically inserted into the first portion of the first through hole  302 ; the second portion of the first through hole  302  is used to fit the part of the connecting column  212 , so that when the first hook portion  211  passes through the first portion and moves to the second portion, the first hook portion  211  locks the connecting column  212  except the position where the first portion communicates with the second portion, to prevent the nose pad  1  from shaking. 
     In some embodiments, the first direction may be radial, for example: the diameter of the first portion is larger than the diameter of the second portion; the diameter of the first hook portion  211  is larger than the diameter of the second portion and smaller than the diameter of the first portion. In this way, the first hook portion  211  can pass through the first portion from the first surface of the fixed plate  20  to reach the second surface, and be clamped within the second portion on the second surface of the fixed plate  20 . 
     In some embodiments, the diameter of the connecting column  212  is smaller than the diameter of the second portion, which can ensure that the connecting column  212  can be located in the second part, so that the first hook portion  211  can be clamped on the second surface of the first mounting plate  301 . 
     It should be noted that the diameter in the embodiments of the present application do not limit that the shapes of the first portion, the second portion and the first hook portion  211  are a circle or an arc, and it can also be a square, an ellipse, etc., and the diameter can also be broadly understood as the circumcircle diameter of a square, etc. 
     In some embodiments, one of the second hook body or the second through hole is further provided on the fixing plate  20 . The second mounting plate  303  of the glass frame body  3  is provided with the other of the second hook body and the second through hole; wherein the first mounting plate  301  and the second mounting plate  303  are arranged in a predetermined angle, and when the fixing plate  20  is installed on the glass frame body  3 , the second hook body is locked in the second through hole. 
     In this embodiment, the nose pad  1  is clamped on the plane of the first mounting plate  301  of the glass frame body  3  through the first hook body  21  and the first through hole  302 . On this basis, the second hook body and the second through hole implement that the nose pad  1  is clamped on the second mounting plate  303  arranged at a preset angle with the first mounting plate  301 , so as to ensure that the connection between the nose pad  1  and the glass frame body  3  is more stable and improve the connection reliability. 
     In some embodiments, the fixing plate  20  may be provided with the second hook body and the glass frame body  3  may be provided with the second through hole, or the fixing plate  20  may be provided with the second through hole and the glass frame body  3  may be provided with the second hook body, which is not limited in this embodiment of the present application.

     In this embodiment, the notch  23  is provided on the fixing plate  20 , and when the limiting member  5  passes through the first mounting plate  301 , the limiting member  5  partially abuts against the notch  23 , so that the limiting member  5  locks the fixing plate  20 . That is, while restricting the movement of the nose pad  1  relative to the glass frame body  3 , this can also reduce the increased volume of the glass frame structure. 
     In some embodiments, the second end of the limiting member  5  is provided with a second hook portion  51 , the second hook portion  51  is located in the third through hole  308 , and in a case that the limiting member  5  is located at the first position, the second hook portion  51  abuts against an inner wall of the third through hole  308 . 
     In some embodiments, when the limiting member  5  is at the first position, the second hook portion  51  is locked on an inner wall of the third through hole  308 , to ensure that the second end of the limiting member  5  can be located in the third through hole  308 , to prevent the limiting member  5  from coming out when the nose pad  1  is removed or replaced. 
     In some embodiments, a locking mechanism is formed by the fixing piece  7 , the limiting member  5  and the elastic member  6 ; and the locking mechanism has a locked state and an unlocked state. The locked state is a state in which the limiting member  5  is located at the second position, and the unlocked state is a state in which the limiting member  5  is located at the first position. 
     When the nose pad  1  needs to be installed, the locking mechanism may be moved (for example, the limiting member  5  is moved) by an external force, to make the locking mechanism at a position of the unlocked state shown in  FIG.  6    (that is, the limiting member  5  is at the first position). In this way, the first hook body  21  can be clamped in the first through hole  302 , and the second hook body  221  can be clamped in the second through hole  304  to realize the installation of the nose pad  1 . In this case, the force acted on the locking mechanism may be released, so that the locking mechanism restores to the position of the locked state shown in  FIG.  5   , thereby realizing the locking of the fixed plate  20  (for example, limiting the movement of the fixed plate  20  in the left and right direction in  FIG.  5   ), to prevent the fixed plate  20  from slipping out. 
     When it is necessary to take out or replace the nose pad  1 , the locking mechanism can be moved by an external force to make the locking mechanism at the position of the unlocked state shown in  FIG.  6   . In this way, the first hook body  21  may slide out of the first through hole  302  to detach from locking, and the second hook body  221  slides out of the second through hole  304 , so that the nose pad  1  is separated from the glass frame body  3 . At this time, the replaced nose pad  1  can be installed on the glass frame body  3  (the process is as described above and is not repeated herein). After the replacement, the force acting on the locking mechanism can be released to restore the locking mechanism to the position of the locked state shown in  FIG.  5   , so as to realize the locking of the fixing plate  20  and prevent the fixing plate  20  from sliding out. 
     Embodiments of the present application further provide a wearable electronic device, including the glass frame structure as described above. The wearable electronic device may be Augmented Reality (AR) glasses, Virtual Reality (VR) glasses, etc., and this embodiment of the present application is not limited thereto. 
     The glass frame structure in the above embodiments of the present application can also be applied to common glasses, such as myopia glasses, hyperopia glasses, decorative glasses, etc., and the embodiments of the present application are not limited thereto. 
     In the above solution, when the user has different types of nose pads to wear, the second end (the second hook portion  51 ) of the limiting member  5  may be pressed, so that the limiting member  5  can be switched from the second position to the first position, that is, the locking mechanism switches from the locked state to the unlocked state, and then the nose pad  1  can be slid out to remove the nose pad  1 . At the same time, the second end of the limiting member  5  can be pressed and slided into the nose pad  1  to realize the installation of the nose pad  1 . This realizes the replaceability of the nose pad  1 , so as to ensure that one glass frame structure can be compatible with different types of requirements of the nose pad  1  of users, and the structural features occupy small space. 
     Each embodiment in this specification is described in a progressive manner, each embodiment focuses on the difference from other embodiments, and the same and similar parts between the embodiments may refer to each other.
