Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram (ECG) watches, and more specifically, to an ECG watch. Background Technology

[0002] The tissues and fluids surrounding the heart are conductive, thus the human body can be viewed as a three-dimensional conductor with length, width, and thickness. The heart is like a power source; the sum of the action potential changes of countless myocardial cells can be conducted and reflected on the body surface. Potential differences exist between many points on the body surface, while many points are equal in electrical potential. During each cardiac cycle, the pacemaker, atria, and ventricles are successively excited, accompanied by changes in bioelectricity. These changes in bioelectricity are called electrocardiograms (ECGs). In recent years, people have worn ECG watches to collect cardiac electrical signals and generate electrocardiogram (ECG) data to assist users in managing their heart health.

[0003] However, existing ECG watches add separate ECG electrode plates to the frame, resulting in a complex structure and increased space consumption. For example, a Chinese national patent discloses a smart ECG watch (application number: CN202022311695.9), which has an upper connector at one end of the outer ring and a lower connector at the other end. Electrode plates are fixedly installed on the upper and lower connectors. The upper connector, lower connector, and electrode plates on them increase the size of the ECG watch, occupy space, and have a complex structure. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, an electrocardiogram (ECG) watch is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an ECG watch, including a bottom case, a middle frame and a transparent watch cover, wherein the bottom case and the watch cover are respectively disposed at the bottom end and the top end of the middle frame, a control circuit board is disposed inside the middle frame, a first electrode electrically connected to the control circuit board is disposed on the bottom surface of the bottom case, and a second electrode is disposed on the upper surface of the watch cover, the second electrode including an upper electrode part located on the upper surface of the watch cover, a lower electrode part located inside the middle frame and a connecting part, the two ends of the connecting part being respectively connected to the upper electrode part and the lower electrode part, and the lower electrode part being electrically connected to the control circuit board.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In addition, the directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. The directional terms are used to better and more clearly explain and understand this utility model, and are not intended to indicate or imply the necessary orientation of this utility model. Therefore, they should not be construed as limitations on this utility model.

[0023] Examples of embodiments of this utility model Figures 1 to 5 As shown, an ECG watch includes a bottom case 1, a middle frame 2, and a transparent watch cover 3. The bottom case 1 and the watch cover 3 are respectively located at the bottom and top of the middle frame 2. The bottom case 1 is made of an insulating material. A control circuit board 4 is disposed inside the middle frame 2. The display screen is disposed on the control circuit board 4, or the watch cover 3 is the display screen. Preferably, the display screen is located at the center of the middle frame 2. When the display screen is disposed on the control circuit board 4, the display screen is a touch screen. The material of the watch cover 3 is any one of tempered glass, acrylic, or polycarbonate that does not affect the touch function of the touch screen, or the material of the watch cover 3 is other materials that do not affect the touch function of the touch screen. A first electrode 5 electrically connected to the control circuit board 4 is disposed on the bottom surface of the bottom case 1, and a second electrode 5 electrically connected to the control circuit board 4 is disposed on the upper surface of the watch cover 3. The second electrode 6 includes an upper electrode portion located on the upper surface of the watch cover, a lower electrode portion located within the middle frame, and a connecting portion. The two ends of the connecting portion are respectively connected to the upper electrode portion and the lower electrode portion. The lower electrode portion is electrically connected to the control circuit board 4, that is, the second electrode 6 is electrically connected to the control circuit board 4. The first electrode 5 on the bottom case 1 is in contact with the hand wearing the watch, and the other hand is in contact with the second electrode 6 on the watch cover 3, thereby forming a closed circuit between the first electrode 5 and the second electrode 6, and transmitting the electrocardiogram (ECG) signal to the control circuit board 4, thereby detecting the ECG and displaying the ECG data on the screen. The two outer walls of the middle frame 2 are each provided with a watch strap 8, which are respectively located on the left and right sides of the middle frame 2. The user wears the ECG watch on their wrist through the two watch straps 8.

[0024] By placing the second electrode 6 on the watch cover 3, there is no need to set up a separate structure on the middle frame 2 for installing the second electrode 6, which reduces the space occupied by the second electrode 6 and avoids contact between the fingers and the back of the hand when touching the second electrode 6, thereby avoiding affecting the test results. The watch can be designed to be thinner, while avoiding opening holes or setting protruding electrodes on the middle frame 2, maintaining the appearance of the ECG watch.

[0025] Further improvements, such as Figure 4 As shown, there are two second electrodes 6, spaced apart. The watch cover 3 has a circular structure, and the second electrodes 6 have an arc-shaped structure with a slight arc. The two second electrodes 6 are located on opposite sides of the top surface of the watch cover 3, near the edge of the watch cover 3, to prevent the second electrodes 6 from affecting the display screen. At this time, there are two electrical connectors 7, which abut against the two second electrodes 6 respectively. The arc-shaped structure allows the second electrodes 6 to cover more area on the watch cover 3. Preferably, insulating silkscreen ink is printed between the two ends of the two second electrodes 6 to prevent short circuit between the two second electrodes 6.

[0026] Further improvements, such as Figure 1 , Figure 3 and Figure 5 As shown, the first electrode 5 is embedded on the bottom surface of the bottom shell 1, and the bottom surface of the first electrode 5 is coplanar with the bottom surface of the bottom shell 1. A conductive first spring 9 is provided on the first electrode 5, and the two ends of the first spring 9 are respectively connected to the first electrode 5 and the control circuit board 4. The bottom shell 1 is provided with a clearance hole to avoid the first spring 9. The first spring 9 can compensate for the assembly tolerance between the bottom shell 1 and the control circuit board 4 in the middle frame 2, so that the first spring 9 maintains a constant contact pressure and the first electrode 5 and the control circuit board 4 will not be disconnected.

[0027] Further improvements, such as Figure 1 and Figure 3 As shown, the first electrode 5 is provided with a guide block 50 for inserting a clearance hole. The top surface of the guide block 50 is provided with a guide groove. One end of the first spring 9 is connected to the bottom of the guide groove. The guide block 50 and the guide groove prevent the first spring 9 from moving horizontally, which facilitates the installation of the first spring 9 during assembly.

[0028] Further improvements, such as Figure 1 and Figure 5As shown, there are two first electrodes 5, which are spaced apart. The bottom shell 1 is circular, and the first electrodes 5 are arc-shaped or slightly curved. The two first electrodes 5 are located on opposite sides of the bottom surface of the bottom shell 1. The arc-shaped structure of the two first electrodes 5 ensures that the first electrodes 5 have sufficient contact area with human skin, resulting in a more stable electrocardiogram signal.

[0029] Further improvements, such as Figure 4 As shown, the control circuit board 4 is provided with an electrical connector 7 that electrically connects the lower electrode part to the control circuit board 4. The electrical connector 7 is any one of a spring, a wire, or a second spring. Preferably, the electrical connector 7 is a spring or a second spring. One end of the spring or the second spring is connected to the control circuit board 4, and the other end of the spring or the second spring abuts against the lower surface of the lower electrode part of the second electrode 6. The spring or the second spring can compensate for the assembly tolerance between the control circuit board 4 and the lower electrode part, so that the spring or the second spring maintains a constant contact pressure and the lower electrode part of the second electrode 6 and the control circuit board 4 will not be disconnected.

[0030] Further improvements, such as Figure 1 and Figure 5 As shown, the second electrode 6 is electroplated or printed on the upper surface of the watch cover 3, which makes the second electrode 6 thin enough to allow for a thinner design of the ECG watch.

[0031] Further improvements, such as Figure 1 and Figure 3 As shown, when the electrical connector 7 is the second spring, both the first spring 9 and the surface of the second spring are plated with gold. Gold has high oxidation resistance and can maintain stable conductivity even after long-term use. At the same time, gold has good ductility, and the gold plating is not easy to crack due to repeated compression, thus avoiding contact failure.

[0032] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
