The trackball is rotatably mounted in the rotating cavity. The cover has a rotating opening and is connected to the base. The rotating opening is opposite to the rotating cavity. The trackball is confined between the rotating cavity and the rotating opening and partially protrudes from the rotating opening to receive external force and rotate. The position detection sensor is provided in the base to detect the track movement of the trackball.

[0008] In one embodiment, the position detection sensor includes an optical sensor or a mechanical sensor.

[0009] In one embodiment, a positioning groove is formed on the outer side wall of the temple, and the cover is attached to the positioning groove and connected to the temple.

[0010] In one embodiment, a hook groove is formed on the outer side wall of the temple, and a hook is formed on the cover at a position corresponding to the hook groove, and the hook is used to buckle into the hook groove and connect with the temple.

[0011] In one embodiment, the smart glasses body includes:

[0012] Frames; and

[0013] The temples are rotatably connected to the frame; wherein,

[0014] The seat is mounted on the temple or the frame.

[0015] In one embodiment, the base is mounted on the lower side of the temple or the frame, so that the portion of the trackball protruding from the rotation opening is disposed downward.

[0016] In one embodiment, the base is mounted on one end of the temple close to the frame, or the base is mounted on one end of the frame close to the temple.

[0017] In one embodiment, the temples include:

[0018] The connecting wall is arranged inside the temple and has a mounting channel formed therein. The seat body is plugged into the mounting channel and connected to the connecting wall.

[0019] In one embodiment, a matching portion is provided on the outer side wall of the base, and the temple further comprises a positioning portion mounted on the outer side wall of the connecting wall;

[0037] like Figure 1 As shown, the smart glasses 100 based on the control of the trackball module 2 proposed in the present invention include a smart glasses body 1 and a trackball module 2. The trackball module 2 includes a base 21, a trackball 22, a cover 23 and a position detection sensor. The base 21 is connected to the smart glasses body 1 and has a rotating cavity formed therein. The trackball 22 is rotatably mounted in the rotating cavity. The cover 23 has a rotating opening. The cover 23 is connected to the base 21, and the rotating opening is opposite to the rotating cavity. The trackball 22 is confined between the rotating cavity and the rotating opening, and partially protrudes from the rotating opening so as to receive external force and rotate. The position detection sensor is provided in the base 21 to detect the track movement of the trackball 22.

[0038] The present invention's technical solution involves attaching a trackball module 2 to the smart glasses. When the user touches and flicks the trackball 22 protruding from the rotating opening, the trackball 22 rotates within the rotating cavity within the base 21, allowing it to rotate freely within a certain range. A position detection sensor captures the movement of the trackball 22 and converts this data into electronic signals, which are then transmitted to the smart glasses' processor for processing. The processor then uses this data to interact with other user interfaces. This allows the user to control the smart glasses through the trackball module, reducing the area occupied by the interactive device on the outside of the smart glasses.

[0039] It is understood that the trackball module 2 can be installed in various locations on the smart glasses, and can be installed according to the shape and required functional areas of the smart glasses without hindering finger touch. At the same time, the base 21 of the trackball module 2 can be located inside the smart glasses body 1. This prevents the trackball 22 from protruding from the smart glasses body 1, achieving a more beautiful and compact design. At the same time, it makes the smart glasses look neater and reduces damage caused by accidental collisions.

[0040] Here, it should be noted that the trackball module 2 can be installed on the left or right side of the smart glasses according to the design requirements of left-handed operation or right-handed operation. When installed on the left side, it can be suitable for left-handed users, and when installed on the right side, it can be suitable for right-handed users. This helps to adapt to different users to improve user comfort and operating efficiency.

[0041] In one embodiment, the position detection sensor includes an optical sensor or a mechanical sensor.

[0042] As will be understood, optical sensors utilize optical principles for position detection. They typically use an LED light source and a photodiode or image sensor to detect the movement of the trackball 22. When the user moves the trackball 22, the texture or markings on its surface reflect light, which is captured by the photodiode or image sensor. The sensor analyzes the changes in the reflected light to determine the direction and speed of the trackball 22's movement. These sensors can measure the position of target objects non-contact and offer advantages such as high accuracy, high speed, and wear resistance.

[0043] Mechanical sensors detect position changes through mechanical contact or displacement. Mechanical sensors detect the movement of the trackball 22 through physical contact. Typically, one or more rollers contact the surface of the trackball 22. As the trackball 22 rolls, the rollers rotate accordingly. Encoders on the rollers record the rotation of the rollers, indirectly measuring the movement of the trackball 22.

[0044] In one embodiment, a magnetic element is disposed inside the trackball 22 , and the position detection sensor includes a magnetic sensor configured to detect the magnetic element inside the trackball 22 and convert the detected magnetic element into a track movement of the trackball 22 .

[0045] It will be appreciated that the magnetic element is typically a small magnet or magnetic material embedded within the trackball 22. When the trackball 22 is moved by the user, the position of the magnetic element changes accordingly. A magnetic sensor is a sensor capable of detecting the strength, direction, or changes in a magnetic field. Common magnetic sensors include Hall effect sensors or magnetoresistive sensors. These sensors can output electrical signals based on changes in the magnetic field, thereby reflecting the motion state of the trackball 22.

[0046] How it works: When stationary, the magnetic element inside the trackball 22 generates a stable magnetic field. When the trackball 22 is moved, the position of the magnetic element changes, causing the direction or strength of the magnetic field to change accordingly. A magnetic sensor detects these changes in the magnetic field and converts them into electrical signals. The processor in the smart glasses receives these signals and uses an algorithm to calculate the direction and displacement of the trackball 22.

[0047] This eliminates physical contact between the magnetic sensor and trackball 22, reducing wear and tear and extending the life of the device. Compared to optical sensors, magnetic sensors are less sensitive to changes in ambient light conditions. They also typically have lower power consumption, which improves the battery life of smart glasses.

[0048] In one embodiment, the trackball module 2 further includes a pressure detection sensor disposed on the base 21 for detecting the pressure exerted by an external force on the trackball 22 .

[0049] As can be understood, when a user applies pressure to the trackball 22, the pressure sensor detects the magnitude and duration of the pressure and converts it into an electrical signal. The smart glasses' processor receives these signals and uses a corresponding algorithm to identify the user's intent, such as executing a click, double-click, or press operation. This enables richer and more intuitive interaction methods, significantly improving the user experience.

[0050] It's important to note that pressure detection sensors are based on resistance, capacitance, or piezoelectric effects. Resistive sensors change resistance when subjected to pressure; capacitive sensors detect pressure by detecting changes in capacitance; and piezoelectric sensors detect pressure by the voltage generated when certain materials are compressed. Compared to adding additional physical buttons, using pressure detection sensors can reduce the complexity and size of smart glasses.

[0051] like Figure 2 As shown, in one embodiment, the smart glasses body 1 includes a frame 11 and temples 12 , the temples 12 are rotatably connected to the frame 11 , and the base 21 is installed on the temples 12 or the frame 11 .

[0052] It is understood that by connecting the frame 11 to the temples 12, the smart glasses can be folded and stored when not in use, thereby reducing the volume required for placement. By mounting the base 21 of the trackball module 2 on the temples 12, the user can easily access the trackball 22 with their fingers without moving their head or sight. Furthermore, the trackball 22 mounted on the temples 12 does not obstruct the user's vision or affect normal use. By mounting the base 21 on the frame 11, the glasses can be adapted to different users' operating habits or working environments.

[0053] For example, the connection between the frame 11 and the temple 12 can be achieved by providing a rotating shaft extending through the rotating connection between the frame 11 and the temple 12. By moving the rotating shaft to the rear of the trackball module 2, the rotating shaft is mounted on the frame 11. In this way, the trackball module 2 can be rotated about the rotating shaft and fixed in a desired position, allowing the user to adjust the position and angle of the trackball module 2 according to personal needs or preferences, thereby improving the personalized adaptability of the device. At the same time, integrating the rotating shaft and the trackball module 2 can reduce the overall size of the device, making the device more compact and portable, and also reduce the complex internal connections of the device, simplifying the design and manufacturing process.

[0054] In one embodiment, the base 21 is mounted on the temple 12 or the lower side of the frame 11 so that the portion of the trackball 22 protruding from the rotation opening faces downward.

[0055] It is understandable that users usually naturally operate from the bottom with their thumb or index finger when using it. This hand movement is more natural and ergonomic, allowing users to control the trackball 22 more easily and accurately, thereby improving operational efficiency. Compared to installing the trackball 22 on the outside of the temple 12 or the frame 11, which requires the user's index finger to contact the trackball 22, the contact of the thumb increases the contact area with the trackball 22, thereby increasing the accuracy of control. Compared to installing the trackball 22 on the upper side of the temple 12 or the frame 11, which allows external rainwater and dust to enter the rotating cavity through the rotating opening, causing the trackball module 2 to malfunction, the service life of the trackball module 2 can be extended.

[0056] It is worth mentioning that mounting the base 21 on the lower side of the temple 12 or the frame 11 can make the overall appearance of the smart glasses more concise and smooth. This design avoids adding extra protrusions on the front or side, reducing visual interference and abruptness.

[0057] In one embodiment, the base 21 is mounted on one end of the temple 12 close to the frame 11 , or the base 21 is mounted on one end of the frame 11 close to the temple 12 .

[0058] It is understandable that by installing the base 21 on the end of the temple 12 close to the frame 11, or installing the base 1 on the end of the frame 11 close to the temple 12, the weight of the smart glasses is reduced to avoid excessive pressure on the nose bridge and ears, which may lead to a poor user experience. For this reason, the frame 11 hung above the ear is usually set to be relatively thin and light, which is not conducive to the user's fingers to touch the trackball 22. The placement close to the frame 11 can reduce the contraction between the human body's arms when touching the trackball 22, making the user feel lighter when touching the trackball 22.

[0059] like Figure 2 and Figure 3 As shown, in one embodiment, a positioning groove 15 is formed on the outer side wall of the temple 12 , and the cover 23 is attached to the positioning groove 15 and connected to the temple 12 .

[0060] It is understood that the positioning groove 15 not only serves to position the cover 23 during installation, simplifying the installation steps and improving installation accuracy, but also the concave design of the positioning groove 15 allows the cover 23 to be partially or completely filled into the positioning groove 15, thereby reducing the portion of the cover 23 protruding from the outer arm of the temple 12 and improving the aesthetics of the smart glasses.

[0061] In one embodiment, a hook groove 16 is formed on the outer side wall of the temple 12 , and a hook 27 is formed on the cover 23 at a position corresponding to the hook groove 16 . The hook 27 is used to snap into the hook groove 16 and connect with the temple 12 .

[0062] It is understood that when the hook 27 on the cover 23 is aligned with the groove 16 on the temple 12 and appropriate pressure is applied, the hook 27 will snap into the groove 16, forming a stable mechanical connection. This connection method not only ensures that the cover 23 is firmly fixed to the temple 12, but also provides a certain degree of detachability, facilitating maintenance and replacement of the cover 23 of the glasses.

[0063] like Figure 3 As shown, in one embodiment, the temple 12 includes a connecting wall 13 disposed inside the temple 12 , wherein a mounting channel is formed inside the temple 12 , and the base 21 is plugged into the mounting channel and connected to the connecting wall 13 .

[0064] It is understood that the presence of the connection wall 13, which supports and secures the base 21 of the trackball module 2, improves the stability of the base 21 and ensures a more secure connection between the trackball module 2 and the temple 12. The base 21 can be installed into the installation channel by plugging, which ensures a tight connection between the base 21 and the connection wall 13 and facilitates disassembly and maintenance.

[0065] In one embodiment, a mating portion 24 is provided on the outer wall of the base body 21, and the temple 12 further includes a positioning portion 14, which is installed on the outer wall of the connecting wall 13; the mating portion 24 is formed with a positioning hole that is adapted to the shape of the positioning portion 14, and the positioning portion 14 is inserted into the positioning hole and fits with the mating portion 24.

[0066] It is understood that during installation, the locating holes on the base 21 are aligned with the locating portions 14 on the temples 12, and then inserted until the locating portions 14 are fully inserted into the locating holes and the base 21 is tightly fitted to the temples 12. The locating portions 14 fit tightly with the locating holes, ensuring that the base 21 is securely fixed to the temples 12 and does not loosen during use. To disassemble, the locating portions 14 can be removed from the locating holes by reversing the process, thereby separating the base 21 and the temples 12.

[0067] In one embodiment, the cover 23 is provided with a fixing hole, and the sidewall of the temple 12 is recessed to form a mounting cavity corresponding to the fixing hole. The trackball module 2 also includes a nut 25 and a screw 26. The nut 25 fills the mounting cavity and is fixed to the temple 12 via a hot melt process. The screw 26 passes through the fixing hole and is threadedly connected to the nut 25 to secure the cover 23 to the temple 12.

[0068] It will be appreciated that the connection between screw 26 and nut 25 secures cover 23 to temple 12, preventing it from loosening or falling off during use. Nut 25 is secured in the mounting cavity via a hot melt process (a widely used joining technique that utilizes the principle of softening, melting, and resolidifying materials at high temperatures to achieve a tight connection between dissimilar materials or components), preventing nut 25 from shifting during use. When disassembly is necessary, screw 26 can be removed from nut 25 by reversing the process, thereby easily separating cover 23 from temple 12.

[0069] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
