Description

Technical Field

[0001] This application relates to the field of watch technology, and in particular to a smart explosion-proof watch. Background Technology

[0002] With technological advancements, smartwatches have expanded from everyday consumer goods to professional fields such as industrial production, bringing convenience to work. In some high-risk industries, such as petrochemicals, mining, and fire rescue, workers require smart devices capable of real-time communication, location tracking, and monitoring of vital signs. However, these environments often contain flammable and explosive gases or dust, and any electronic equipment must meet stringent explosion-proof standards to prevent it from becoming an ignition source.

[0003] Currently, for electronic devices in hazardous locations, intrinsically safe circuit design is one of the most mainstream explosion-proof technologies used in watches. Its core principle is to limit the voltage and current of the circuit to an extremely low level, ensuring that the electrical sparks or thermal effects generated by the circuit under normal operating or fault conditions are insufficient to ignite specific hazardous gases.

[0004] While intrinsically safe circuit designs can control electrical energy at its source, they primarily protect against ignition energy generated within the circuit itself. Their protection against large-scale energy release (thermal runaway and explosion) caused by strong external physical impacts is limited. The chemical energy stored in a lithium battery far exceeds the limits set by intrinsically safe circuits. Utility Model Content

[0005] This application provides a smart explosion-proof watch to solve the problem that current smart watches are prone to danger when subjected to impacts in special locations.

[0006] A smart explosion-proof watch, comprising:

[0007] The device body includes a housing, a display screen assembly, a main control module, and a power module. The display screen assembly, the main control module, and the power module are sequentially disposed on the housing along the thickness direction. The housing is made of a high-hardness plastic material composed of PC and ABS. The main control module is electrically connected to the display screen assembly and the power module. The power module includes a battery compartment and a battery, with the battery compartment housing the battery. The power module also includes a foam cushioning layer and an aramid fiber cloth. The foam cushioning layer is disposed on the inner wall of the battery compartment, and the aramid fiber cloth covers the battery and has a thickness of 0.2 mm.

[0008] By employing the above technical solutions, the casing combines the excellent impact resistance, heat resistance, and high strength of PC with the good processability and surface finish of ABS. This makes the watch casing robust and durable, effectively resisting daily bumps and impacts. The foam cushioning layer excels at absorbing and dissipating external impact energy, preventing physical damage caused by drops and collisions. Meanwhile, the high-strength aramid fiber fabric (such as Kevlar) provides excellent puncture resistance and acts as a strong external restraint in the event of thermal runaway expansion of the battery, preventing the battery casing from rupturing and fragments from flying, thus effectively preventing secondary disasters.

[0009] In one embodiment, the housing includes a decorative element, a front shell, and a bottom shell. The decorative element and the bottom shell are disposed on opposite sides of the front shell. The decorative element is fixed to the display screen assembly. The main control module and the power module are both disposed between the front shell and the bottom shell, and the battery compartment is disposed inside the bottom shell. The front shell and the bottom shell are fixed together with PUR adhesive.

[0010] By adopting the above technical solution, the shell is divided into decorative parts, front shell and bottom shell, which facilitates production, assembly and maintenance; PUR is a reactive polyurethane hot melt adhesive, which cures by reacting with moisture in the air to form extremely strong adhesion, thereby providing stronger structural bonding strength, so that the front shell and bottom shell are firmly combined into a whole, which is not easy to crack due to external impact or pressure from internal battery bulging. At the same time, PUR adhesive can fill tiny gaps to form a reliable waterproof and dustproof seal.

[0011] In one embodiment, the battery compartment is provided with vents.

[0012] By adopting the above technical solution, in some emergency situations (such as battery thermal runaway or large-area impact), the battery pressure will rise sharply and the high-pressure gas will be discharged through the vent, thus avoiding an explosion caused by excessive pressure.

[0013] In one embodiment, a protective shell is provided between the power module and the main control module, and the protective shell is made of a high-hardness plastic material composed of PC and ABS.

[0014] By adopting the above technical solution, the protective shell plays the role of physical isolation and "firewall". Even if the battery fails, it can provide an additional layer of physical impact and flame retardant protection for the main control module behind it.

[0015] In one embodiment, the protective shell includes an inner layer, a middle layer, and an outer layer in sequence along the thickness direction away from the power module. The inner layer is made of a thermally conductive metal, the middle layer is made of a phase change material, and the outer layer is made of a high-hardness plastic material combining PC and ABS.

[0016] By employing the above technical solution, the inner layer is tightly attached to the power module. When the battery begins to overheat abnormally, this metal layer can quickly conduct heat away from the hot spot and evenly distribute it across the entire protective shell, preventing localized overheating. The phase change material in the middle layer absorbs a large amount of heat energy during its transition from solid to liquid, while its own temperature remains constant. This material can absorb a large amount of heat when the battery temperature rises sharply, preventing heat from continuing to transfer to the main control module and buying valuable time for safe handling. The outer layer provides structural support.

[0017] In one embodiment, the watch body further includes a SIM card tray, the faceplate has a through hole, the SIM card tray passes through the through hole and is disposed inside the faceplate, the SIM card tray is located between the power module and the main control module, and the faceplate further includes a sealing member disposed in the through hole.

[0018] By adopting the above technical solution, the gap between the protective shell and the main control module is fully utilized, maximizing space utilization. Meanwhile, the SIM card slot, as a structural component, objectively provides additional support and isolation between the main control module and the power module, further enhancing the structural strength and security of this area. By adding a sealing element (such as a silicone ring), the opening can be effectively sealed, ensuring that moisture and dust cannot enter from here, thus maintaining the high protection level of the entire device.

[0019] In one embodiment, the battery is a solid-state battery, and the solid-state battery uses a solid electrolyte.

[0020] By adopting the above technical solution, solid-state batteries replace flammable organic electrolytes with solid electrolytes, fundamentally eliminating the risk of combustion and explosion. At the same time, some explosion-proof components can be simplified or even removed, resulting in a thinner and lighter watch.

[0021] In one embodiment, the shell includes an internally hollow frame and a non-Newtonian fluid filled within the frame.

[0022] By employing the above technical solution, a non-Newtonian fluid is filled inside the watch case frame, utilizing its property of "strengthening under pressure." During normal wear, the fluid keeps the watch flexible; upon sudden impact, the fluid instantly hardens, absorbing and dispersing the impact energy, thereby protecting the internal movement and screen.

[0023] In one embodiment, the shell includes a hollow frame and a magnetorheological fluid filled within the frame, the inner wall of which is provided with an electromagnetic coil and electrically connected to the main control module.

[0024] By adopting the above technical solution, the electromagnetic coil is controlled by the main control module. At the instant before impact, the main control module drives the coil to generate a strong magnetic field, and the ferromagnetic particles in the magnetorheological fluid rapidly arrange themselves into chains, causing the liquid to "solidify" instantly. The hardness of the case can be increased by several orders of magnitude within milliseconds.

[0025] In one embodiment, the main control module includes a six-axis gyroscope.

[0026] By adopting the above technical solution, a six-axis gyroscope (usually referring to a combination of a three-axis gyroscope and a three-axis accelerometer, i.e., an inertial measurement unit, IMU) can accurately sense the angular velocity and acceleration of an object in three-dimensional space. It can detect violent movements far exceeding the conventional action threshold in real time and at high speed, such as a watch that is in free fall or undergoing a violent impact. The detected abnormal signals will be immediately transmitted to the main control module as a trigger command to facilitate the solidification of the magnetorheological fluid.

[0027] In summary, this application includes at least one beneficial effect:

[0028] 1. The casing combines the excellent impact resistance, heat resistance, and high strength of PC with the good processability and surface finish of ABS. This makes the watch casing robust and durable, effectively resisting daily bumps and impacts. The foam cushioning layer excels at absorbing and dissipating external impact energy, preventing physical damage caused by drops and collisions. Meanwhile, high-strength aramid fiber fabric (such as Kevlar) provides excellent puncture resistance and acts as a strong external restraint in the event of thermal runaway expansion of the battery, preventing the battery casing from rupturing and fragments from flying, thus effectively preventing secondary disasters.

[0029] 2. Solid-state batteries use solid electrolytes instead of flammable organic electrolytes, fundamentally eliminating the risk of combustion and explosion. This also allows for the simplification or even removal of some explosion-proof components, resulting in a lighter and thinner watch.

[0030] 3. The electromagnetic coil is controlled by the main control module. At the instant before impact, the main control module drives the coil to generate a strong magnetic field. The ferromagnetic particles in the magnetorheological fluid rapidly arrange themselves into chains, causing the liquid to "solidify" instantly. The hardness of the case can increase by several orders of magnitude within milliseconds. Attached Figure Description

[0037] The following description, in conjunction with Figures 1-5, provides a further detailed explanation of the smart explosion-proof watch provided in this application.

[0038] Example 1

[0039] Please refer to Figures 1-5. The smart explosion-proof watch provided in this embodiment includes a watch body 1 and a watch strap 2.

[0040] As shown in Figure 1(a), Figure 1(b) and Figure 2 As shown, the watch body 1 includes a housing 11, a display assembly 12, a main control module 13, and a power module 14. The display assembly 12, the main control module 13, and the power module 14 are sequentially disposed on the housing 11 along the thickness direction. The main control module 13 is electrically connected to the display assembly 12 and the power module 14. The power module 14 includes a battery compartment 141 and a battery 142, with the battery compartment 141 covering the battery 142.

[0041] Specifically, the housing 11 serves to house and protect the internal components. The housing 11 includes a decorative element 111, a front shell 112, and a bottom shell 113. The decorative element 111 and the bottom shell 113 are located on opposite sides of the front shell 112 along its thickness direction. The decorative element 111 is fixed to the display assembly 12, thus stabilizing its position. In this embodiment, the decorative element 111, the front shell 112, and the bottom shell 113 are all made of a high-strength plastic material combining PC and ABS with a thickness ≥1.0mm, a hardness HV of 300, and a yield strength ≥205MPa. Furthermore, their surfaces can be coated with an impact-resistant composite coating. Additionally, the internal reinforcing rib layout of the front shell 112 can be optimized through ANSYS topology analysis, resulting in a 40% increase in bending strength. A PUR adhesive is provided between the front shell 112 and the bottom shell 113. The PUR adhesive has good adhesion properties and a temperature resistance range of -40℃ to 120℃. It requires a separation force of more than 50N to separate, which improves the protective performance of the shell 11 and prevents the shell from decomposing and causing harm to the human body due to the explosion of the battery 142.

[0042] The display assembly 12 is used to display various information, such as time and motion data. It typically includes a front cover, a display screen, and a driving circuit. The front cover is fixed to the decorative piece 111 and protects the display screen. The front cover can be made of double-tempered glass with a thickness of 1.5mm and a bending strength greater than or equal to 800MPa. The display screen can be a TFT screen, which has good display effect and low power consumption. The driving circuit is responsible for controlling the display content of the screen. It is electrically connected to the main control module 13 and receives signals from the main control module 13.

[0043] The main control module 13 is the core control component of the watch, comprising functional modules such as a 5G module, a dual-frequency single Beidou positioning module, and a Bluetooth module. The 5G module enables high-speed data transmission and rapid information exchange with the outside world. The 5G module can utilize the TD Tech MT5710. The TD Tech MT5710-CN series is a 5G RedCap module based on 3GPP Release 17 technology, supporting 5G SA networking and backward compatible with 4G. Compared to traditional 4G Cat 4 modules, the MT5710-CN series modules reduce power consumption by approximately 30%. Furthermore, RedCap technology itself further optimizes power consumption by reducing the number of antennas and lowering bandwidth. The dual-frequency single-BeiDou positioning module can use the CC0218B chip, which achieves ultra-low power consumption through advanced process design, extending battery life by 142 seconds. It also features high sensitivity, anti-multipath capability, strong anti-interference ability, and high-precision BeiDou joint positioning technology, enabling accurate positioning. Outdoors, it can combine with a 5G network to achieve high-precision positioning within 2 meters; indoors, Bluetooth beacons are deployed at a distance of approximately 8 meters to fill blind spots. These electronic components in the main control module 13 are typically integrated on a motherboard, and their electrical connections are achieved through circuitry on the motherboard. In addition, the watch uses laser engraving (LDS) technology to carve a 3D spiral structure on the inside of the case 112, realizing the integrated use of 5G (3.5GHz), Beidou (1.6GHz), and Bluetooth (2.4GHz) multi-band antennas, reducing space occupation and improving the compactness of the device; in addition, the antenna adopts an orthogonal layout design, that is, the antennas of different frequency bands are perpendicular to each other in space, with an isolation of >25dB (traditional solutions <15dB), which can effectively reduce electromagnetic interference between antennas and make signal transmission more stable.

[0044] The main control module 13 may also include a six-axis gyroscope (accelerometer and gyroscope), which collects motion characteristics in real time and combines them with 5G base station positioning assistance information to construct a multi-dimensional behavior recognition model. Specifically, when a person's continuous movement speed is detected to be >1m / s and the linearity of the movement trajectory is >0.8, the person is in patrol mode; when the angular velocity variance is <0.1 rad² / s² and the displacement amplitude is <0.5m / 30s, the person is in confined space mode; when the peak value of the three-axis acceleration is >4g and the frequency domain energy mutation rate is >200%, the person is in SOS mode. The main control module 13 can quickly switch modes to ensure the transmission of emergency signals.

[0045] like Figure 3As shown, the watch body 1 also includes a SIM card tray 15. A through hole 1121 is provided on one side of the face shell 112 along the width direction. The SIM card tray 15 passes through the through hole 1121 and is located inside the face shell 112. The SIM card tray 15 is located between the power module 14 and the main control module 13. Specifically, the face shell 112 may also be provided with a sealing element 1122. The sealing element 1122 is provided in the through hole 1121 for sealing and waterproofing, preventing external moisture and flammable and explosive gases from entering the watch through the through hole 1121. The watch body 1 also includes a button module 16. The button module 16 is located on the other side of the face shell 112 along the width direction and corresponds to the through hole 1121. The button module 16 includes a button 161 and a button FPC 162. The button 161 protrudes from the face shell 112 and has two along the length direction, including a power button 161 and an SOS button 161. The button FPC 162 is electrically connected to the main control module 13. By pressing the button 161, the watch functions can be operated.

[0046] like Figure 4 As shown, the watch body 1 also includes a heart rate FPC module 17, which is located between the power supply module 14 and the bottom shell 113. The heart rate FPC module 17 is electrically connected to the main control module 13 and can monitor the user's heart rate data in real time, transmitting the data to the main control module 13 for processing and display. Specifically, the heart rate FPC module 17 may include an optical PPG sensor, which mainly measures heart rate by detecting changes in light reflection or transmission on the skin surface, but is easily interfered with under high-intensity exercise. Therefore, PPG light signals, accelerometer, and gyroscope data can be fused to establish a three-dimensional motion trajectory model. At the same time, an improved variable step size LMS algorithm is used to effectively eliminate motion noise by dynamically adjusting the step size parameters; the LED light source intensity (10-150mA) and sampling frequency (25-100Hz) are dynamically adjusted to adapt to different intensities of exercise, ensuring stable signals in various complex environments.

[0047] The main control module 13 also includes a temperature-sensing patch resistor and a barometric pressure sensor. It constructs a multi-dimensional compensation model—a three-parameter compensation model encompassing ambient temperature (T_ambient), blood flow velocity (V_blood), and barometric pressure (P_baro)—to measure body temperature in real time under conditions of high-temperature radiation, oil contamination, or rapid temperature changes, with an error of less than ±0.5℃. Additionally, the watch utilizes capacitive contact monitoring (threshold 200kΩ, 10-second sliding window filtering, requiring three consecutive exceedances of the threshold to trigger an alarm) and optical liveness verification: analyzing the PPG signal spectral entropy (liveness > 0.5) and verifying heart rate consistency (0.6-1.2Hz) to confirm whether the watch is actually being worn by a person.

[0048] like Figure 5As shown, the power module 14 provides power support for the normal operation of the watch. Specifically, the power module 14 includes a battery compartment 141 and a battery 142, with the battery compartment 141 housing the battery 142. The battery compartment 141 is located inside the bottom case 113. In this embodiment, the battery compartment 141 forms a ring around the battery 142 inside the bottom case 113. The surface of the battery compartment 141 may have ventilation holes with a diameter of 0.8mm. When the watch is impacted, pressure is released through the ventilation holes with a response time of <5ms, which can promptly reduce the pressure inside the battery compartment 141 and prevent danger caused by excessive pressure. The battery 142 can be a lithium battery 142, which has advantages such as high energy density and long service life. The power module also includes a foam cushioning layer and aramid fiber cloth. The foam cushioning layer is located on the inner wall of the battery compartment 141. The foam cushioning layer has good cushioning performance, with a compression rate of 30%, and can absorb a 20G instantaneous impact, effectively reducing the impact of external impacts on the battery 142. The battery 142 is covered with an aramid fiber cloth, which can be made of Kevlar fiber, preferably 0.2mm thick, with a tensile strength ≥3000MPa. It possesses high strength and high toughness, and can restrain the battery 142 in the event of expansion or rupture, preventing battery fragments from flying and causing danger. The foam cushioning layer can be replaced with a silicone cushioning pad, and the aramid fiber cloth can be replaced with other high-strength fiber cloths, as long as they meet similar explosion-proof and cushioning requirements.

[0049] A protective shell 18 is provided between the power module 14 and the main control module 13 to prevent potential problems with the power module 14 from affecting the main control module 13, further improving the safety of the watch. The protective shell 18 can be made of metal or high-strength plastic, which has a certain degree of hardness and impact resistance. In this embodiment, the protective shell 18 is also made of a high-hardness plastic shell combining PC and ABS.

[0050] The watch also includes two straps 2, which are located on opposite sides of the watch body 1 and hinged to the case 11. The two straps 2 can be fastened together. Specifically, the function of the straps 2 is to secure the watch to the wrist. The fastening method can be either a snap-on or magnetic. Snap-on fastening is more common and simple to operate; magnetic fastening offers better stability and aesthetics. The straps 2 can be made of leather, rubber, or nylon. Leather straps 2 have a good texture, rubber straps 2 are durable and have some elasticity, and nylon straps 2 are lightweight and breathable.

[0051] The implementation principle of this embodiment is as follows: This smart explosion-proof watch improves its explosion-proof performance through a reasonable structural design and the application of multiple explosion-proof measures. The casing 11 uses high-strength materials and high-performance sealant to effectively prevent the ingress of flammable and explosive gases from the outside; the power module's multiple protective measures, such as the battery compartment, foam buffer layer, and aramid fiber cloth, provide comprehensive protection for the battery; the positioning and communication modules integrated into the main control module 13 enable the watch to have powerful functions and also allow it to contact the outside world in a timely manner in dangerous environments. Compared with existing technologies, this watch has significant improvements in battery 142 protection, overall sealing, and circuit safety control, better meeting the needs of use in special dangerous environments and ensuring the safety of workers and the smooth operation of work.

[0052] Example 2

[0053] The difference between this embodiment and the previous embodiment is that the protective shell 18 has a multi-layer structure and includes an inner layer, a middle layer, and an outer layer sequentially along the thickness direction away from the power module 14. The inner layer uses a high thermal conductivity metal material, such as copper foil or graphene composite heat-conducting sheet. Its core function is to quickly and evenly conduct away any local hot spots that may be generated by the battery 142, avoiding heat accumulation. The middle layer uses microencapsulated phase change material. When the battery 142 abnormally heats up, the heat-conducting layer quickly conducts the heat to the phase change material layer. When the phase change material reaches a specific temperature (such as 60°C), it melts from a solid state to a liquid state, absorbing a large amount of latent heat without significantly increasing its own temperature. The outer layer facing the main control module 13 still uses high-strength PC+ABS material. In this embodiment, the battery 142 can be a solid-state battery, using a solid electrolyte inside, thus having higher safety and stability.

[0054] In addition, the structure of the shell 11 has also been changed. A hollow frame is made using 3D printing technology. The frame is filled with a non-Newtonian fluid and sealed with a high-toughness flexible film (such as TPU). This fluid is liquid under normal conditions, but it will harden instantly when subjected to rapid impact.

[0055] The implementation principle of this embodiment is as follows: by dividing the protective shell 18 into three layers, it can not only effectively buffer the impact force from the outside, but also absorb the heat generated by the power module 14, further protecting the battery 142. By making the shell 11 into a frame containing a non-Newtonian fluid, the fluid solidifies instantly under high-speed and violent impact, forming a super-rigid whole with the frame, dispersing the impact force across the entire frame and reducing the damage to the inside of the watch.

[0056] Example 3

[0057] The difference between this embodiment and the previous embodiment is that the faceplate 112 includes a hollow frame and a magnetorheological fluid filled within the frame. An electromagnetic coil is located on the inner wall of the frame and electrically connected to the main control module 13. The magnetorheological fluid is a smart material whose rheological properties can be controlled by an external magnetic field. When the watch is subjected to an external impact, the main control module 13 detects the impact signal via a six-axis gyroscope and controls the electromagnetic coil to generate a magnetic field, causing the magnetorheological fluid to harden rapidly, thus providing cushioning and protection. Compared to non-Newtonian fluids, the magnetorheological fluid has a faster response speed and can more accurately adjust its hardness according to the impact.

[0058] The implementation principle of this embodiment is as follows: by utilizing the intelligent properties of magnetorheological fluid, combined with the synergistic effect of a six-axis gyroscope and an electromagnetic coil, it is possible to sense the impact on the watch in real time and quickly adjust the state of the magnetorheological fluid to provide more efficient and precise protection for the watch.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
