Description

Technical Field

[0001] This utility model relates to the technical field of electronic glasses, specifically to a magnetic energy sensing glasses. Background Technology

[0002] With the advancement of technology, electronic products have also flourished, with products changing rapidly and update cycles becoming increasingly shorter. When making calls, listening to music, or other audio content, people often use Bluetooth headsets to connect to their phones or other audio playback devices to avoid disturbing others. Among these, there are multifunctional Bluetooth headset glasses that integrate Bluetooth headset functionality into the temples of the glasses. However, simply integrating existing Bluetooth headsets into the temples still cannot meet the needs of users.

[0003] During the use of the glasses, opening the glasses allows the Bluetooth headset module to work, and closing the glasses turns it off, thus saving power. In existing technology, the opening and closing of the temples triggers a contact switch (mechanical trigger) to send a command to the Bluetooth headset module. However, this mechanical triggering method results in unsmooth temple movement and hinge jamming, thus reducing the user experience.

[0004] Since Bluetooth headset modules are existing technology and their functionality is achieved through the combination of multiple hardware structures, when applied to the temples of glasses, the layout and assembly structure of the circuit board needs to be considered. Some existing temples have circuit boards, but their structural layout tends to result in thicker and larger temples, which reduces comfort when worn on the ears. Utility Model Content

[0005] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a magnetic energy sensing glasses that can overcome the technical problem of the influence of power-on and power-off operations on the hinge structure, and can perform power-on and power-off operations while maintaining smooth opening and closing of the temples.

[0006] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0007] A magnetic energy sensing glasses includes a frame, temples, and hinges. The temples are rotatably connected to the frame via the hinges. A permanent magnet is fixedly mounted on the frame. The hinges include a first fixing frame, a second fixing frame, and a pivot. One end of the first fixing frame is fixed to the frame, and the other end of the first fixing frame is rotatably connected to the second fixing frame via the pivot. The second fixing frame is fixed to the temple and is a magnetic conductor. When the temples are open, the magnetic conductor is close to the permanent magnet; when the temples are closed, the magnetic conductor is away from the permanent magnet. A mounting compartment is provided on the inner side of the temples, and a circuit board is assembled inside the mounting compartment. A Hall element is provided at one end of the circuit board. The Hall element is close to the magnetic conductor and is used to sense the opening and closing state of the temples to control the operation of the circuit board.

[0008] Preferably, the rear end of the second fixing frame is provided with a U-shaped part, the Hall element is close to the side of the U-shaped part, and the two ends of the U-shaped part are inserted into the slots of the temple.

[0009] Preferably, the circuit board includes a power supply module, a Hall sensor module, and a microprocessor module. The power supply module provides a power supply voltage VBAT, and the microprocessor module receives a power trigger signal PWRKEY from the Hall sensor module. The Hall sensor module includes a diode D1, an NPN transistor, resistors R7, R11, R6, R8, and R10, and a Hall chip U4. The collector of the NPN transistor is connected to the anode of the diode D1 and one end of the resistor R8 to output the power trigger signal PWRKEY. The base of the NPN transistor is connected to one end of the resistor R7 and one end of the resistor R11. The cathode of the diode D1 is connected to the other end of the resistor R11, one end of the resistor R6, and the fifth pin of the Hall chip U4. The fourth pin of the Hall chip U4 is connected to one end of the resistor R10 and the other end of the resistor R8. The other end of the resistor R10 is connected to the power supply voltage VBAT. The emitter of the NPN transistor, the other end of the resistor R7, the other end of the resistor R6, and the second pin of the Hall chip U4 are all grounded.

[0010] Preferably, resistors R7, R6, and R8 have a resistance value of 0 ohms.

[0011] Preferably, the Hall chip U4 uses the model OCH4002STAD.

[0012] Preferably, diode D1 is a light-emitting diode.

[0013] Preferably, an audio amplifier module is also connected to the microprocessor, and the audio amplifier module uses a chip U3 with the model number LTK5136.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves smooth folding of the temples and frames via a hinge, while the permanent magnet can also attract the second fixing frame of the hinge. Since the second fixing frame is a magnetic conductor, it guides the magnetic field. At this time, the magnetic field of the second fixing frame is different when the temple is open and closed. Therefore, the Hall element set in the mounting compartment of the temple can sense the change of the magnetic field, thereby judging the state of the temple and triggering an electrical signal to control the circuit board. With this solution, the hinge moves smoothly and reliably. The permanent magnet can not only attract the magnetic conductor, but the magnetic conductor can also change the magnetic field to judge the change of the temple position.

[0016] 2. In this utility model, the second fixing bracket uses the U-shaped part to improve the Hall element's ability to detect magnetic fields, and its structure can also fit into the slot, thereby improving the firmness of the assembly.

[0017] 3. In this utility model, the circuit board employs reliable peripheral circuitry to achieve reliable signal transmission and provides filtering and noise reduction. Furthermore, it utilizes 0-ohm resistors. While seemingly contradictory, 0-ohm resistors (also known as jumper resistors or zero-ohm links) play an irreplaceable role in wiring optimization, debugging and testing, signal integrity, and circuit protection due to their near-zero resistance. In high-density PCB layouts, when traces intersect or space is limited, 0-ohm resistors can be used as jumpers, avoiding manual wiring or increasing the number of layers, significantly improving production efficiency. During circuit development, 0-ohm resistors serve as temporary connection points, allowing for quick module disconnection to isolate faults. Connecting digital ground and analog ground with 0-ohm resistors forms a single-point ground, reducing digital noise interference with ADC sampling.

[0018] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation.

Those skilled in the art can understand the specific meaning of the above terms in the invention based on the specific circumstances.

[0032] Example 1:

[0033] This invention discloses a magnetic energy sensing glasses, as per an embodiment. Figure 1 , Figure 2 and Figure 3 As shown, the frame includes a frame 1, temples 2, and hinges 3. The temples 2 are rotatably connected to the frame 1 via hinges 3. A permanent magnet 4 is fixedly mounted on the frame 1. The hinge 3 includes a first fixing bracket 31, a second fixing bracket 32, and a pivot 33. One end of the first fixing bracket 31 is fixed to the frame 1, and the other end is rotatably connected to the second fixing bracket 32 ​​via the pivot 33. The second fixing bracket 32 ​​is fixed to the temple 2 and is a magnetic material. The magnetic material here refers to the material of the second fixing bracket 32 ​​being magnetically conductive; it can be iron, cobalt, nickel alloy, etc. The permanent magnet 4 is a common magnet.

[0034] When the temple 2 is open, the magnetic conductor is close to the permanent magnet 4; when the temple 2 is closed, the magnetic conductor is away from the permanent magnet 4; a mounting compartment 21 is provided on the inner side of the temple 2, and a circuit board 5 is assembled in the mounting compartment 21. A Hall element 511 is provided at one end of the circuit board 5. The Hall element 511 is close to the magnetic conductor and is used to sense the opening and closing state of the temple 2 to control the operation of the circuit board 5. Therefore, it can be seen that while the hinge 3 enables the smooth folding of the temple 2 and the frame 1, the permanent magnet 4 can also attract the second fixing frame 32 of the hinge 3. Since the second fixing frame 32 is a magnetic conductor, it can guide the magnetic field. At this time, the magnetic field of the second fixing frame 32 is different when the temple 2 is open and closed. Thus, the Hall element 511 set in the mounting compartment 21 of the temple 2 can sense the change of the magnetic field, thereby judging the state of the temple 2 and triggering an electrical signal to control the circuit board 5. In this scheme, the hinge 3 moves smoothly and reliably. The permanent magnet 4 can not only attract the magnetic conductor, but the magnetic conductor can also change the magnetic field to judge the change of the position state of the temple 2.

[0035] To further improve the reliability of assembly and magnetic energy sensing, a U-shaped portion 34 is provided at the rear end of the second mounting bracket 32. The Hall element 511 is located near the side of the U-shaped portion 34, and both ends of the U-shaped portion 34 are inserted into the slots 22 of the temple 2. The second mounting bracket 32 ​​utilizes the U-shaped portion 34 to enhance the detection capability of the Hall element 511 for magnetic fields, and its structure can also fit into the slots 22, thereby improving the stability of the assembly.

[0036] refer to Figure 4 , Figure 5 and Figure 6 Circuit board 5 includes a power supply module 52, a Hall effect sensor module 51, and a microprocessor module 53. Although the specific circuitry of the microprocessor module 53 is not shown, it can be a microcontroller circuit module in the prior art, using the AB5756C microcontroller chip. Its datasheet and applications can be found in existing technologies.

[0037] In this plan Figure 6In this circuit, power module 52 provides a supply voltage VBAT. VBAT is both a power supply terminal marker and a signal terminal name marker. As those skilled in the art will understand, the same marker symbol indicates a common connection. Microprocessor module 53 receives a power trigger signal PWRKEY from Hall sensor module 51. Hall sensor module 51 includes diode D1, NPN transistor, resistors R7, R11, R6, R8, R10, and Hall chip U4. The collector of the NPN transistor is connected to the anode of diode D1 and one end of resistor R8 to output the power trigger signal PWRKEY. The base of the NPN transistor is connected to one end of resistor R7 and one end of resistor R11. The cathode of diode D1 is connected to the other end of resistor R11, one end of resistor R6, and the fifth pin of Hall chip U4. The fourth pin of Hall chip U4 is connected to one end of resistor R10 and the other end of resistor R8. The other end of resistor R10 is connected to the supply voltage VBAT. The emitter of the NPN transistor, the other end of resistor R7, the other end of resistor R6, and the second pin of Hall chip U4 are all grounded. Resistors R7, R6, and R8 are 0 ohms. The Hall effect chip U4 is an OCH4002STAD. Diode D1 is a light-emitting diode. Circuit board 5 employs reliable external circuitry to ensure reliable signal transmission and provides filtering and noise reduction. While 0-ohm resistors (also known as jumper resistors or zero-ohm links) may seem contradictory, their near-zero resistance plays an irreplaceable role in wiring optimization, debugging and testing, signal integrity, and circuit protection. In high-density PCB layouts (circuit board 5), when traces cross or space is limited, 0-ohm resistors can be used as jumpers, avoiding manual jumper wires or increasing the number of layers, significantly improving production efficiency. During circuit development, 0-ohm resistors serve as temporary connection points, allowing for quick module disconnection to isolate faults. Connecting digital ground and analog ground with 0-ohm resistors creates a single-point ground, reducing digital noise interference with ADC sampling.

[0038] refer to Figure 7 As shown, an audio amplifier module 54 is also connected to the microprocessor. The audio amplifier module 54 uses a chip U3, model LTK5136. Figure 7 In the circuit shown, modulation is achieved through resistors and capacitors, resulting in the input signal DACL# of chip U3 being sent by the microcontroller. The outputs L- and L+ of chip U3 are connected to a speaker or audio player. VBAT is the power voltage provided by power module 52. This circuit enables volume control. Furthermore... Figure 5 The device includes a touch module, microphone module, indicator light module, and antenna module 55, which are features found in some existing Bluetooth headsets. This will be briefly described here without further explanation or detail.

The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations.
