[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Please combine Figure 1-5This utility model discloses a smartwatch 10 with a parent-child modular structure, which can meet the basic functional needs of general consumers as well as other special functional needs, and can reduce product costs. The smartwatch includes a parent module 100 and at least one child module 200 electrically connected to the parent module 100. The parent module 100 is the main body of the smartwatch, providing basic functions to the user; the child module 200 is an expansion module for meeting the user's customized functional needs. In use, the user can select a child module 200 with specific functions and assemble it with the parent module 100 to meet their own functional requirements for the watch. The mother module 100 includes a watch case 101, a watch strap 102 fixed to the outer surface of the watch case 101 and worn on the wrist, a display screen 103 mounted on the main surface of the watch case 101, a camera 104 fixed to the main surface or side of the watch case 101, a control circuit board 105 housed in the inner cavity of the watch case 101 and electrically connected to the display screen 103 and the camera 104, a power module 106 housed in the inner cavity of the watch case 101 and electrically connected to the control circuit board 105, a communication module 107 housed in the inner cavity of the watch case 101 and used for communication with an external smart terminal, and a communication terminal 108 penetrating one side of the watch case 101 and electrically connected to the control circuit board 105. The camera 104 is used to capture images, and the display screen 103 is used to display the images captured by the camera 104, as well as images or other information data captured from an external smart terminal via the communication module 107. The submodule 200 includes a housing 201, a wiring portion 202 that passes through the housing 201 and is electrically connected to a communication terminal 108, and at least one environmental monitoring element 203 that is housed within the cavity of the housing 201 and electrically connected to the wiring portion 202. The submodule 200 and the parent module 100 are electrically connected and transmit signals through the cooperation of the communication terminal 108 and the wiring portion 202, so that signals detected by the environmental monitoring element 203 are sent to the control circuit board 105 and further displayed on the display screen 103, facilitating the user to obtain relevant environmental parameters.

[0025] The aforementioned smartwatch 10 with a parent-child module structure expands the watch's functionality by setting a communication terminal on the side of the watch case 101 of the parent module 100 and electrically connecting the sub-module 200, which is equipped with an environmental monitoring element 203, to the communication terminal. The parent module 100 can meet the basic functional needs of general consumers, while the sub-module 200 can meet the special functional needs of users in certain industries. Different sub-modules 200 with different functions can be designed according to the differentiated needs of different users and connected to the parent module 100 to supplement its functions. This eliminates the need for customized development of the entire watch, reducing R&D and production costs and improving the product's market competitiveness.

[0026] In this solution, the mother module and the sub-module are connected in two interchangeable ways. Specifically, in one embodiment, the watch case 101 has a fixing part 109 on the side where the communication terminal 108 is located. The outer shell 201 is disposed at the fixing part 109 and connected to the watch case 101 by screws or clips. The wiring part 202 is a wiring terminal. In this embodiment, the sub-module 200 is detachably installed on the side of the watch case 101 of the mother module 100. This facilitates the user's start, stop, and operation of the sub-module 200, and also reduces the impact on the overall thickness of the watch case 101, improving the user's comfort when wearing the smartwatch. Preferably, in this embodiment, the outer shell 201 is fixedly connected to the watch case 101 by two screws 204 passing through its two opposite sides. Further, the fixing part 109 is a strip-shaped protrusion on one side of the watch case 101, and the outer shell 201 has a recess 205 that mates with the strip-shaped protrusion. The wiring part 202 is located within the recess 205. By providing a strip-shaped protrusion on the side of the watch case 101 and a recess 205 on the outer casing 201, pre-positioning of the watch case 101 and the outer casing 201 can be achieved, allowing the connection parts of the two to be quickly aligned, thereby reducing the difficulty of connecting them. Preferably, each of the two opposite sides of the strip-shaped protrusion has a ramp portion, and the strip-shaped protrusion as a whole has a frustum-shaped structure. The inner contour shape of the recess 205 of the outer casing 201 is adapted to the outer contour shape of the strip-shaped protrusion, so that when the mother module 100 and the sub-module 200 are assembled, the strip-shaped protrusion can be quickly inserted into the recess 205 and aligned for connection, thereby further reducing the assembly difficulty of the mother module 100 and the sub-module 200.

[0027] In another embodiment, the outer casing 201 and the watch case 101 are spaced apart, and the wiring portion 202 is a cable extending outward from the inside of the outer casing 201 and electrically connected to the communication terminal 108. In other words, in this embodiment, the outer casing and the watch case are not assembled, so that the user can connect the sub-module to the parent module in certain special circumstances to collect relevant environmental information.

[0028] In this embodiment, the front of the watch case 101 is the side facing away from the wrist when the smartwatch is worn, and the back of the watch case 101 is the side that fits against the skin of the wrist when the smartwatch is worn. This explanation can also be applied to other embodiments. The interior of the watch case 101 is hollow to house the control circuit board 105 and related components. The projection of the watch case 101 onto the wrist is a circular, rectangular, pentagonal, hexagonal, octagonal, decagonal, or dodecagonal structure. Preferably, in this embodiment, the projection of the watch case 101 onto the wrist is a rectangular structure, and the corners of the outer ring of the watch case 101 are provided with beveled surfaces to prevent scratches to the user. The power module 106 is a rechargeable battery electrically connected to the control circuit board 105, used to provide operating voltage for the smartwatch's circuitry. In this embodiment, the watch strap 102 can be an integral and elastic strap. The two ends of the watch strap 102 are fixedly connected to two opposite sides of the watch case 101, so that the smartwatch can be worn on the wrist by the cooperation of the watch strap 102 with the human wrist. The watch strap 102 can also include an independent first strap body and a second strap body. One end of the first strap body is fixedly connected to one outer side of the watch case 101, and one end of the second strap body is fixedly connected to the other outer side of the watch case 101. The other ends of the first strap body and the other ends of the second strap body are connected by a buckle or belt buckle, so that the smartwatch can be worn on the human wrist.

[0029] The communication module 107 connects to an external smart terminal via Bluetooth, Wi-Fi, or a ZigBee network. In one embodiment, the communication module 107 connects to an external smartphone via Bluetooth. In this case, the smartwatch functions as a portable display device for the smartphone and also as a signal acquisition and detection device for the smartwatch. In another embodiment, the communication module 107 connects to the external smart terminal via Wi-Fi or a ZigBee network, and can also connect to the cloud via Wi-Fi or a ZigBee network. In this case, the smartwatch can be used as an independent smart terminal to load data from the external smart terminal or the cloud.

[0030] In one embodiment, the mother module 100 further includes a microphone 110 disposed on the main surface of the case 101 and located next to the display screen 103. The microphone 110 is electrically connected to the control circuit board 105. By providing the microphone 110 on the mother module 100, the smartwatch can collect ambient or user sound signals through the microphone 110 and convert the sound signals into electrical signals. The control circuit board 105 processes the electrical signals through its main control chip to complete the input of sound commands or the storage of sound information; or, when the user makes or receives a call through the smartwatch, the microphone 110 can acquire the user's speech content. Furthermore, the case 101 has a sound outlet 111 and a pressure detection hole 112 communicating with the inner cavity of the case 101 on its outer side facing away from the fixing part 109. The mother module 100 also includes a speaker 113 housed in the inner cavity of the case 101 and corresponding to the sound outlet 111, and a pressure sensor 114 corresponding to the pressure detection hole 112. The speaker 113 and the pressure sensor 114 are electrically connected to the control circuit board 105. Further preferably, the control circuit board 105 is equipped with an audio module electrically connected to the main control chip. This audio module is electrically connected to the speaker 113 to control the speaker 113 to play corresponding audio content or warning messages. A barometric pressure sensor 114 is used to measure the absolute pressure of the air in the environment so that the user can understand the current air pressure conditions. In this embodiment, the side of the casing 101 is also equipped with a channel button 115 and a volume knob 116 between the sound outlet 111 and the pressure detection hole 112. The control circuit board 105 is equipped with a first coded switch triggered by the channel button 115 and a second coded switch triggered by the volume knob 116. Thus, when the audio module controls the speaker 113 to play audio, the user can switch the played audio or adjust the audio volume by pressing the channel button 115 or rotating the volume knob 116.

[0031] In one embodiment, the mother module 100 further includes a charging terminal 117 disposed on the side of the watch case 101 and electrically connected to the power module 106. A recess 118 is provided on the side of the watch case 101 where the charging terminal 117 is located. The inner contour shape of the recess 118 conforms to the outer contour shape of the external charging connector. The charging terminal 117 is located within the recess 118, and a magnetic attraction part 119 is provided on each side of the edge of the recess 118 for magnetically connecting with the external charging connector. By providing a recess 118 on the side of the watch case 101, it is convenient to quickly position the external charging connector when the smartwatch is charging, so that the terminals on the charging connector can be quickly aligned with the charging terminal 117 on the watch case 101, reducing the difficulty of charging the smartwatch. By providing magnetic attraction parts 119 on the edge of the recess 118, the magnetic attraction parts 119 can be magnetically connected to the corresponding parts on the charging connector, achieving a stable connection between the smartwatch and the charging connector, preventing the charging connector from falling off the recess 118 during the charging process, and ensuring the reliability of the smartwatch charging operation. Preferably, the magnetic part 119 is a sheet magnet embedded in the side of the watch case 101, the surface of the magnetic part 119 is flush with the side of the watch case 101, and the charging connector is provided with magnetic contacts that magnetically engage with the magnetic part 119.

[0032] In one embodiment, the mother module 100 further includes a temperature and humidity sensor 120, an attitude sensor 121, and a geomagnetic sensor 122, housed within the inner cavity of the watch case 101 and electrically connected to the control circuit board 105. The detection end of the temperature and humidity sensor 120 is located on the outside of the watch case 101. The temperature and humidity sensor 120 is used to detect ambient temperature and humidity. The attitude sensor 121 includes motion sensors such as an accelerometer, a gyroscope (angular velocity sensor), and a magnetometer. It is used to measure the attitude (direction and angle) of the user's arm in three-dimensional space and to measure the acceleration of the user's arm to calculate the number of steps taken. The geomagnetic sensor 122 is a sensor capable of sensing the Earth's magnetic field. It can determine its own orientation and position by measuring the strength and direction of the Earth's magnetic field. The geomagnetic sensor 122 typically consists of three magnetic field sensors that measure the strength and direction of the Earth's magnetic field in the X-axis (pointing to the magnetic north pole), Y-axis (pointing to the magnetic east), and Z-axis (perpendicular to the ground and upwards), respectively. When placed in a specific location, the geomagnetic sensor 122 measures the strength and direction of the Earth's magnetic field at that location. For example, if the geomagnetic sensor 122 measures the strongest magnetic field in the X-axis direction, its direction is determined to be towards the geomagnetic north pole; if the geomagnetic sensor 122 measures the strongest magnetic field in the Y-axis direction, its direction is determined to be towards the geomagnetic east. The user can determine their own geomagnetic location using the geomagnetic sensor 122 inside the watch case 101. In this embodiment, the ambient temperature and humidity data detected by the temperature and humidity sensor 120, the human posture and movement data detected by the posture sensor 121, and the geomagnetic information of the user's location detected by the geomagnetic sensor 122 are all transmitted to the display screen 103 via the control circuit board 105 for display, allowing the user to obtain the relevant information.

[0033] In one embodiment, the mother module 100 further includes a vital signs sensor 123 housed within the cavity of the watch case 101 and electrically connected to the control circuit board 105. The detection end of the vital signs sensor 123 is located on the back of the watch case 101 and fits against the skin of the wrist when worn. In this embodiment, the vital signs sensor 123 is a combined sensor for monitoring and collecting human vital signs data, including a blood oxygen saturation sensor, an electrocardiogram (ECG) sensor, a body temperature sensor, and a heart rate variability sensor. The blood oxygen saturation sensor uses spectral principles to measure the oxygen content in the blood to obtain human blood oxygen data; the ECG sensor captures ECG signals through skin electrodes to collect electrical activity data of the heart (ECG data); the body temperature sensor measures the temperature of the human body surface to obtain the user's body temperature data; and the heart rate variability sensor analyzes changes in heart rate intervals to assess the state of the autonomic nervous system.

[0034] In one embodiment, the environmental monitoring element 203 is a methane sensor, a water pressure sensor, a laser rangefinder, or a formaldehyde sensor. The methane sensor detects the methane concentration in the environment, allowing for a rapid response when the methane concentration exceeds the limit. The water pressure sensor directly applies the pressure of the water being measured to the sensor's diaphragm, causing a micro-displacement proportional to the water pressure. This changes the sensor's resistance, and the internal circuitry detects this resistance change, outputting a standard measurement signal corresponding to the pressure, thus achieving the purpose of water pressure detection. The laser rangefinder measures the distance of a specified target from the user. Specifically, it emits a laser pulse at the target using a laser diode. After reflection from the target, the laser light scatters in all directions, with some of the scattered light returning to the laser rangefinder's receiver. The receiver then transmits the light to the optical system and images it onto an avalanche photodiode. The avalanche photodiode is an optical sensor with internal amplification capabilities, capable of detecting extremely weak light signals. By recording and processing the time elapsed from the emission of the light pulse to its return and reception, the target distance can be determined. The formaldehyde sensor is used to detect the formaldehyde content in the environment. In this embodiment, the formaldehyde sensor is one of the following: a formaldehyde oxide gas sensor, a formaldehyde gas molecular sieve sensor, a formaldehyde surface acoustic wave gas sensor, a visual fluorescent formaldehyde sensor, and a formaldehyde gas electronic nose. In actual production, other types of environmental monitoring elements 203 can be selected according to the user's needs, such as setting an infrared sensor inside the housing 201, etc., which will not be elaborated here.

[0035] Additionally, the housing 201 may contain only one of the following sensors: a methane sensor, a water pressure sensor, a laser rangefinder sensor, and a formaldehyde sensor; or it may contain two or more of these sensors. When multiple sensors are installed in the housing 201, each sensor is connected to the communication terminal 108 via the wiring section 202 to transmit the collected data to the display screen 103 for display. Depending on the number and size of the environmental monitoring elements 203 installed in the housing 201, the housing 201 may be designed as a hollow, thin-shell structure resembling a C-shape, or as a trapezoidal structure with a hollow interior. The corners of the housing 201 are rounded to prevent scratches to the user. The housing 201 also has a control switch 206 for controlling the connection between the environmental monitoring elements 203 and the wiring section 202 to activate or deactivate the corresponding functions of the submodule 200.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
