Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a blood pressure monitor watch. Background Art

[0002] Smart wearable devices are portable products that can be worn on the body or integrated into clothing or accessories. They leverage software support and data interaction to achieve powerful functionality. As an emerging sector in the consumer electronics industry, smartwatches are widely used in sports, healthcare, and entertainment. They leverage sensors, wireless connectivity, and other technologies to enable a variety of novel and engaging interactions, and are gaining increasing recognition and popularity among users. Currently, smartwatches can measure blood pressure, greatly facilitating users' health monitoring.

[0003] Smart watches that need to measure blood pressure usually require more components such as air pumps, air chambers, and air pressure sensors to be placed in the body of the smart watch. This causes at least the following problems: 1. The body of the smart watch becomes bulky and the user's wearing comfort is poor; 2. There are many components inside the body of the smart watch, which makes assembly difficult and leads to low production efficiency; 3. There are many parts inside the body of the smart watch, and a messy layout will affect the use of each component.

[0004] In view of this, how to solve the problem of the existing technology to research and design a blood pressure watch has become the subject to be studied and solved by the present invention. Utility Model Content

[0005] The purpose of the utility model is to provide a blood pressure monitor watch.

[0006] To achieve the above-mentioned purpose, the present invention proposes a blood pressure watch, which includes a housing assembly and a mainboard assembly, an air pump assembly, a battery assembly, a screen assembly, and an airbag assembly installed on the housing assembly;

[0007] The housing assembly includes a side housing and a bottom housing;

[0008] The screen assembly is assembled and positioned with the housing assembly through the top of the side housing;

[0009] The side shell, bottom shell and screen assembly define the internal space of the shell assembly;

[0010] The mainboard assembly and the air pump assembly are located in the internal space of the shell. The mainboard assembly includes a mainboard body and a pressure sensor. The pressure sensor has a sensor plug-in interface. The air pump assembly includes an air pump body and an air pump plug-in interface. In the assembled state, one side of the air pump body is positioned and mounted on the mainboard assembly, and the other side is positioned and mounted on the raised rib of the side shell. There is a certain gap between the air pump body and the screen assembly; the sensor plug-in interface and the air pump plug-in interface extend toward the bottom shell.

[0011] The battery assembly is assembled in the interior space of the shell, and the battery assembly is arranged close to one side of the interior space of the shell, and the sensor plug-in interface and the air pump plug-in interface are arranged close to the other side of the interior space of the shell;

[0012] The bottom shell is provided with a first through hole and a second through hole corresponding to the sensor plug-in interface and the air pump plug-in interface, and the distances from the centers of the first through hole and the second through hole to one side of the side shell are substantially the same;

[0013] The airbag assembly includes an airbag body, a first airbag connector and a second airbag connector;

[0014] There are only two air flow paths inside the shell assembly, one of which is formed by inserting the first airbag connector into the first through hole and interferingly docking with the sensor internal plug-in interface, and the other air flow path is formed by inserting the second airbag connector into the second through hole and interferingly docking with the air pump internal plug-in interface.

[0015] The relevant contents of this utility model are explained as follows:

[0016] 1. In the above technical solution of the utility model, in order to solve the problems of existing smart watches with blood pressure measurement function, such as many internal devices, large size, difficult assembly, and messy layout, an innovative blood pressure meter watch with more reasonable internal structure layout and better assembly production is designed. In this blood pressure meter watch, the air pump body in the air pump assembly is connected to the mainboard assembly and then assembled into the shell assembly, so that the assembly accuracy of the air pump body is higher and can be confirmed by the previous process before being installed into the shell assembly to avoid problems in subsequent assembly. Since the positioning connection between the mainboard assembly and the side shell is more convenient and the positioning accuracy is high, the assembly and positioning of the air pump assembly is more convenient, and the gap between the air pump assembly and the screen assembly is more controllable and accurate, avoiding damage to the air pump assembly or the screen assembly during assembly; the position layout of the larger air pump assembly and battery assembly is also specially designed. The sensor plug-in interface and the air pump plug-in interface are both arranged away from the screen assembly, and the battery assembly is arranged close to one side of the inside of the side shell, and the sensor plug-in interface and the air pump plug-in interface are arranged close to the other side of the inside of the side shell, so that the position layout of the larger air pump assembly and battery assembly is more reasonable, and the space occupied by the air pump body is cleverly positioned, so that the shell assembly as a whole will not be too bloated, making it more comfortable for users to wear; in this, there are only two air flow paths inside the shell assembly, which are not connected to each other, and there is no need to form an air chamber inside the shell assembly, which greatly reduces the airtightness requirements of the shell assembly, thereby further reducing material costs and assembly costs, and can reduce the wearing weight of the watch body, alleviate the discomfort caused by long wearing time, and also avoid inaccurate measurements caused by poor sealing of the air chamber, reducing labor replacement costs.

[0017] 2. In the above technical solution, the air pump body includes a first overlapping skirt and a second overlapping skirt located on the left and right sides, and an air pump welding pin located on the upper side. The air pump body is fixed to the mainboard welding pins on the mainboard body by welding the air pump welding pins, and then assembled into the shell assembly from the back of the shell as a whole with the mainboard body. The air pump body overlaps the raised rib of the side shell through the first overlapping skirt. This specific structure makes the overlapping and welding of the air pump body and the mainboard body more reliable and stable, so that the mainboard assembly and air pump assembly can be accurately positioned before the overall assembly of the blood pressure watch. While the position of the mainboard body can be accurately positioned with the assembly position of the side shell, the gap between the air pump assembly and the screen assembly is also more controllable, thereby improving product consistency.

[0018] 3. In the above technical solution, the main board body has a notch, the second overlapping skirt of the air pump body is overlapped on one side of the notch, the air pump welding pin of the air pump body is welded to the main board welding pin on the other side of the notch, the air pump body passes through the notch of the main board body toward the front for a distance, and a gap is formed between the surface of the air pump body facing the front and the surface of the screen assembly facing the back. With this design, the larger air pump body can better and more utilize the internal space of the side shell, further avoiding the overall bloatedness of the shell assembly, so that the shell assembly of the smart watch with blood pressure measurement function can be made thinner.

[0019] 4. In the above technical solution, the gap between the air pump body and the back of the screen assembly is greater than or equal to 0.5 mm. This size design is used to prevent the vibration generated by the air pump body during operation from affecting the screen assembly.

[0020] 5. In the above technical solution, mounting holes are provided at the other three corners of the main body except the notch, and a mounting seat is correspondingly provided at the reverse side of the side shell. The main body is fixed to the mounting seat of the side shell by fasteners passing through the mounting holes. This design allows the main body to be more accurately assembled to the shell assembly, thereby further improving the assembly accuracy of the air pump assembly fixedly connected to the main body.

[0021] 6. In the above technical solution, the blood pressure watch also includes a first strap and a second strap installed at the upper and lower ends of the shell assembly through spring ears. A connecting hole is provided on the first strap. The airbag main body is a strip-shaped structure. The airbag main body is provided with a boss at the first end of the belt-shaped structure. The boss is detachably connected to the connecting hole on the first strap. With this design, when the airbag main body is in use, in addition to the airbag connector being inserted into the through hole to connect and dock with the pressure sensor and the air pump internal plug-in interface, the airbag main body can also be connected to the first strap through the boss at the first end of the airbag main body, thereby further improving the stability of the airbag main body when the blood pressure watch measures blood pressure.

[0022] 7. In the above technical solution, the airbag connector is provided on the same side of the airbag body as the boss. After the first end of the airbag body is connected to the first watch strap, and the first airbag connector and the second airbag connector are respectively connected and docked with the sensor plug-in interface and the air pump plug-in interface, the second end of the airbag body extends toward the length direction of the second watch strap. This design enables the airbag body to fully surround the user's wrist, with good wrapping and more accurate measurement information.

[0023] 8. In the above technical solution, the second watchband is provided with buckle holes at intervals along the length direction, and a length indicator area is provided on the surface of the second watchband on one side of the buckle hole. The length number in the length indicator area indicates the corresponding length, allowing the user to more quickly and accurately select the position that suits their wrist size to wear the airbag body and watchband, thereby ensuring reliable measurement information.

[0024] 9. In the above technical solution, the first airbag joint and the second airbag joint are hollow cylindrical bodies, and undercuts are provided on the peripheral sides of the hollow cylindrical bodies. The undercuts are engaged and clamped with the front-facing surfaces of the peripheral sides of the first through hole and the second through hole on the bottom shell, thereby increasing the stability of the airbag.

[0025] 10. In the above technical solution, the first through hole and the corresponding sensor plug-in interface are located on the same axis, and the second through hole and the corresponding air pump plug-in interface are located on the same axis, so that the insertion position of the airbag connector in the airbag assembly is more accurate, and the airbag connector can be accurately docked with the pressure sensor and the air pump plug-in interface.

[0063] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0064] The utility model aims to solve the problems of existing smart watches with blood pressure measurement function, such as the large number of internal components, large size, difficult assembly, and messy layout. An innovative blood pressure monitor watch is designed with a more reasonable internal structure layout and better assembly and production.

[0065] like Figures 1 to 10 As shown, a blood pressure watch is proposed in an embodiment of the present invention, which includes a shell assembly 1 and a mainboard assembly 2, an air pump assembly 3, a battery assembly 4, a screen assembly 5, and an airbag assembly 6 installed on the shell assembly 1.

[0066] like Figure 1 As shown, the housing assembly 1 includes a side housing 11 and a bottom housing 12 .

[0067] like Figure 3 As shown, the screen assembly 5 is assembled and positioned with the housing assembly 1 through the top of the side housing 11 .

[0068] The inner space of the housing assembly 1 is defined by the side housing 11 , the bottom housing 12 , and the screen assembly 5 .

[0069] like Figure 3As shown, the mainboard assembly 2 and the air pump assembly 3 are located in the internal space of the shell, the mainboard assembly 2 includes a mainboard body 21 and a pressure sensor 22, the pressure sensor has a sensor plug-in interface 221, the air pump assembly 3 includes an air pump body 31 and an air pump plug-in interface 32. In the assembled state, one side of the air pump body 31 is positioned and installed on the mainboard assembly 2, and the other side is positioned and installed on the raised rib of the side shell 11. There is a certain gap between the air pump body 31 and the screen assembly 5; the sensor plug-in interface 221 and the air pump plug-in interface 32 extend toward the bottom shell 12.

[0070] like Figure 3 As shown, the battery assembly 4 is assembled in the internal space of the shell, and the battery assembly 4 is arranged close to one side of the internal space of the shell, and the sensor plug-in interface 221 and the air pump plug-in interface 32 are arranged close to the other side of the internal space of the shell.

[0071] like Figure 3 As shown, the bottom shell 12 is provided with a first through hole 121 and a second through hole 122 corresponding to the sensor plug-in interface 221 and the air pump plug-in interface 32, and the distances from the centers of the first through hole 121 and the second through hole 122 to one side of the side shell are roughly the same.

[0072] like Figure 9 As shown, the airbag assembly 6 includes an airbag body 61 , a first airbag connector 62 and a second airbag connector 63 .

[0073] like Figure 12 As shown, there are only two air flow paths inside the shell assembly 1, one of which is formed by inserting the first airbag connector 62 into the first through hole 121 and interferingly docking with the sensor internal plug-in interface 221, and the other is formed by inserting the second airbag connector 63 into the second through hole 122 and interferingly docking with the air pump internal plug-in interface 32.

[0074] Through the implementation of the embodiment of the present invention, the air pump body 31 in the air pump assembly 3 is connected to the main board assembly 2 and then assembled into the shell assembly 1, so that the assembly accuracy of the air pump body 31 is higher, and it can be confirmed by the previous process before being installed into the shell assembly 1, avoiding problems in subsequent assembly. Since the positioning connection between the main board assembly 2 and the side shell 11 is more convenient and the positioning accuracy is high, the assembly and positioning of the air pump assembly 3 is more convenient, and the gap between the air pump assembly 3 and the screen assembly 5 is more controllable and accurate, avoiding damage to the air pump assembly 3 or the screen assembly 5 during the assembly process; the position layout of the larger air pump assembly 3 and the battery assembly 4 is also specially designed, and the sensor is plugged in The port 221 and the air pump plug-in interface 32 are both arranged away from the screen assembly, and the battery assembly 4 is arranged close to one side of the inside of the side shell 11, and the sensor plug-in interface 221 and the air pump plug-in interface 32 are arranged close to the other side of the inside of the side shell 11, so that the position layout of the larger air pump assembly and battery assembly is more reasonable, and the space occupied by the air pump body is cleverly positioned, so that the shell assembly as a whole will not be too bloated, making it more comfortable for users to wear; in this, there are only two air flow paths inside the shell assembly, which are not connected to each other, and there is no need to form an air chamber inside the shell assembly, so the airtightness requirements of the shell assembly are greatly reduced, thereby further reducing material costs and assembly costs.

[0075] In another embodiment of the present invention, Figure 7 As shown, the air pump body 31 includes a first overlapping skirt 311 and a second overlapping skirt 312 on the left and right sides, and an air pump welding pin 313 on the upper side. The air pump body 31 is welded to the mainboard welding pin 211 on the mainboard body 21 via the air pump welding pin 313, and then assembled into the housing assembly 1 from the rear of the housing as a whole with the mainboard body 21. The air pump body 31 is overlapped on the raised rib of the side housing 11 via the first overlapping skirt 311. This specific structure makes the overlapping and welding of the air pump body 31 and the mainboard body 21 more reliable and stable, so that the mainboard assembly 2 and the air pump assembly 3 can be accurately positioned before the overall assembly of the blood pressure watch. While the position of the mainboard body 21 can be accurately positioned with the assembly position of the side housing 11, the gap between the air pump assembly 3 and the screen assembly 5 is also more controllable, thereby improving product consistency.

[0076] Specifically, such as Figure 6 As shown, the main body 21 has a notch 210. Figure 8As shown, the second overlapping skirt 312 of the air pump body 31 is overlapped on one side of the notch 210, and the air pump welding pin 313 of the air pump body 31 is welded to the mainboard welding pin 211 located on the other side of the notch 210. The air pump body 31 passes through the notch 210 of the mainboard body 21 toward the front for a distance, and a gap is formed between the surface of the air pump body 31 facing the front and the surface of the screen assembly 5 facing the back. With this design, the larger air pump body 31 can better and more utilize the internal space of the side shell 11, further avoiding the overall bloatedness of the shell assembly 1, so that the shell assembly 1 of the smart watch with blood pressure measurement function can be made thinner.

[0077] More specifically, Figure 6 As shown, the main board body 21 is provided with mounting holes 212 at the other three corners except the notch 210, and a mounting seat 111 is correspondingly provided at the reverse side of the side shell 11. The main board body 21 is fixed to the mounting seat 111 of the side shell 11 by fasteners passing through the mounting holes 212. This design can more accurately assemble the main board body 21 to the shell assembly 1, thereby further improving the assembly accuracy of the air pump assembly 3 fixedly connected to the main board body 21.

[0078] Furthermore, the gap between the air pump body 31 and the back of the screen assembly 5 is greater than or equal to 0.5 mm. This size design is used to prevent the vibration generated when the air pump body 31 is working from affecting the screen assembly 5.

[0079] In another embodiment of the present invention, Figure 13 As shown, the blood pressure watch also includes a first strap 71 and a second strap 72 mounted on the upper and lower ends of the housing assembly 1 through spring ears. A connecting hole 711 is provided on the first strap 71. The airbag body 61 is a belt-shaped structure. Figure 9 As shown, the airbag body 61 is provided with a boss 611 at the first end of the band structure, and the boss 611 is detachably connected to the connecting hole 711 on the first strap 71. With this design, when the airbag body 61 is in use, in addition to the airbag connector 62 being inserted into the through hole 121 to connect and dock with the pressure sensor 22 and the air pump internal plug-in interface 32, the boss 611 at the first end of the airbag body 61 can also be used to connect to the first strap 71, thereby further improving the stability of the airbag body 61 when the blood pressure watch measures blood pressure.

[0080] Further, such as Figure 13As shown, the airbag connector 62 is provided on the airbag main body 61 on the same side as the boss 611. After the first end of the airbag main body 61 is connected to the first strap 71, and the first airbag connector 62 and the second airbag connector 63 are respectively connected and docked with the sensor plug-in interface 221 and the air pump plug-in interface 32, the second end of the airbag main body 61 extends toward the length direction of the second strap 72. With this design, the airbag main body 61 can fully surround the user's wrist, with good wrapping and more accurate measurement information.

[0081] More specifically, Figure 14 As shown, the second strap 72 is provided with buckle holes 721 at intervals along the length direction, and the second strap 72 is provided with a length indication area 720 on the surface of one side of the buckle holes 721. The length number in the length indication area 720 identifies the corresponding length, allowing the user to more quickly and accurately select the position that suits the size of their wrist to wear the airbag body 61 and the strap, thereby making the measurement information reliable.

[0082] In other embodiments of the present invention, the first airbag joint 62 and the second airbag joint 63 are hollow cylindrical bodies, and undercuts 64 are provided on the peripheral sides of the hollow cylindrical bodies. The undercuts 64 are engaged and clamped with the front-facing surfaces of the peripheral sides of the first through hole 121 and the second through hole 122 on the bottom shell 12 to increase the stability of the airbag.

[0083] In another embodiment of the present invention, the first through hole 121 and the corresponding sensor plug-in interface 221 are located on the same axis, and the second through hole 122 and the corresponding air pump plug-in interface 32 are located on the same axis, so that the insertion position of the airbag connector 62 in the airbag assembly 6 is more accurate, and the airbag connector 62 can be accurately docked with the pressure sensor 22 and the air pump plug-in interface 32.

[0084] Several major components and working processes of the embodiment of the utility model are introduced as follows.

[0085] The entire blood pressure monitor watch of the embodiment of the present invention is composed of multiple components, including a shell component 1, a mainboard component 2, an air pump component 3, a battery component 4, a screen component 5, an airbag component 6, a strap component, etc.

[0086] Blood pressure detection process: After wearing the blood pressure monitor, the user operates the side button of the watch to light up the display screen to enter the blood pressure measurement mode. After the air pump assembly 3 starts working, it inflates the airbag assembly 6 through the air inlet channel. The airbag assembly 6 and the pressure sensor 22 are connected to receive the gas change pressure signal, calculate the systolic pressure, diastolic pressure, and pulse, and finally the output value is displayed on the display screen.

[0087] The embodiment of the present utility model is aimed at a blood pressure monitor watch with a more reasonable internal structure layout and better assembly and production, and has the following layout and design.

[0088] The housing assembly 1 is composed of a side housing 11 and a bottom housing 12 . A mounting seat 111 is provided on the reverse side of the side housing 11 , and a first through hole 121 and a second through hole 122 are provided on the bottom housing 12 .
