[0034] The following describes the implementation methods of the embodiments of the present application in conjunction with the accompanying drawings. These implementation methods are only exemplary and are not intended to limit the embodiments of the present application.

[0035] An embodiment of the present application provides an electronic blood pressure monitor. Figure 1 is a schematic diagram of an electronic sphygmomanometer according to an embodiment of the present application, showing an overall stereogram (wherein an upper housing of the electronic sphygmomanometer is not included); Figure 2 is another schematic diagram of the electronic blood pressure meter of the embodiment of the present application, showing a top view of the electronic blood pressure meter when viewed from the upper side (wherein the upper housing of the electronic blood pressure meter is not included); Figure 3 is a schematic diagram of a housing of an electronic blood pressure meter according to an embodiment of the present application, showing a bottom view of the housing viewed from the bottom after the wristband structure is removed; Figure 4 is a schematic diagram of a wristband structure of an electronic blood pressure monitor according to an embodiment of the present application, showing a view of the wristband structure observed from the upper rear after the host is removed; Figure 5 is along Figure 2 A cross-sectional view taken along line AA'; Figure 6 is along Figure 3 A cross-sectional view taken along line BB'; Figure 7 is another schematic diagram of the wristband structure of the electronic blood pressure monitor according to an embodiment of the present application, showing a view of the wristband structure viewed from the rear side; Figure 8 yes Figure 7 Enlarged view of the dashed box T1.

[0036] like Figures 1 to 4 As shown, the electronic blood pressure monitor 1 may include: a host 10 and a wristband structure 20, wherein the host 10 has a shell 11 provided with a first clamping portion 12; the wristband structure 20 has a joint portion 21 abutting against the shell 11 and a second clamping portion 22 provided on the upper surface F1 of the joint portion 21, the upper surface F1 of the joint portion 21 abuts against the lower surface F2 of the shell 11, and the wristband structure 20 is detachably fixedly connected to the shell 11 by the clamping of the first clamping portion 12 and the second clamping portion 22.

[0037] In the embodiments of the present application, Figure 3 and Figure 6 As shown, the first engaging portion 12 may include: a first through hole 121, a wall portion 122 and a convex portion 123, wherein the first through hole 121 may be rectangular and penetrate the housing 11 in a first direction, the wall portion 122 extends upward from a first side 121a of the first through hole 121 along the first direction, and the convex portion 123 extends from the wall portion 122 to a second side 121b of the first through hole 121 in a second direction;

[0038] like Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the second locking portion 22 may include a main body portion 221, which extends upward from the upper side surface F1 of the coupling portion 21 along the first direction, at least a portion of the main body portion 221 in the first direction is accommodated in the first through hole 121, the main body portion 221 is provided with a second through hole 2211 that penetrates the front side surface F3 and the rear side surface F4 of the main body portion 221 in the second direction, the protrusion 123 is accommodated in the second through hole 2211, and the protrusion 123 is clearance-matched with the second through hole 2211.

[0039] According to the above embodiment, by accommodating the protrusion 123 of the first engaging portion 12 in the second through hole 2211 of the main body 221 of the second engaging portion 22 and matching with the clearance therebetween, the housing 11 and the wristband structure 20 can be more tightly engaged in the up and down directions, and the joint between the two is less likely to become loose, thereby reducing the phenomenon of the air intake pipe being broken during repeated use.

[0040] In the embodiments of the present application, for example, Figure 3 As shown, the first through hole 121 is rectangular, and accordingly the first through hole 121 has a first side 121a on the front side, a second side 121b on the rear side, a third side 121c on the left side and a fourth side 121d on the right side, that is, the first side 121a and the second side 121b are opposite in the second direction, and the third side 121c and the fourth side 121d are opposite in the fourth direction.

[0041] In the embodiment of the present application, the first through hole 121 may be as follows Figure 3 The rectangular through hole shown in FIG. 21 may have a main body 221 as shown in FIG. Figure 8 As shown, the side surface in the third direction is flat, and the straight side of the rectangle cooperates with the flat side surface of the main body 221 to facilitate the insertion of the main body 221 in the up and down directions, but the present application is not limited to this. The first through hole 121 can also be a through hole of other shapes. Based on this, the side surface of the main body 221 in the third direction can also be designed to be a surface corresponding to the shape of this through hole (for example, the circular through hole corresponds to the side surface of the main body 221 in the third direction is an arc surface); that is, as long as the protrusion extending from the wall portion 122 formed on one side of the first through hole 121 is accommodated in the second through hole 2211, the first through hole 121 can be of other shapes.

[0042] In the embodiment of the present application, the shape of the protrusion 123 is adapted to the shape of the second through hole 2211 (for example, the protrusion 123 and the second through hole 2211 are both rectangular), so that the protrusion 123 and the second through hole 2211 can be a clearance fit, which is conducive to the insertion and removal of the protrusion 123 in the second through hole 2211, thereby facilitating the disassembly and assembly of the wristband structure 20 and the host 10, but the present application is not limited to this. The protrusion 123 can also abut the inner surface of the second through hole 2211, that is, the outer peripheral surface of the protrusion 123 and the inner surface of the second through hole 2211 are an interference fit, which is more conducive to the positioning of the second clamping portion 22 in the up and down directions.

[0043] In the embodiment of the present application, the length of the protrusion 123 in the second direction can be the same as the length of the second through hole 2211 in the second direction, that is, the protrusion 123 in the second direction just fills the second through hole 2211, but the length of the protrusion 123 in the second direction can be less than the length of the second through hole 2211 in the second direction (that is, the protrusion 123 in the second direction only occupies a part of the second through hole accommodating space), or, the length of the protrusion 123 in the second direction can be greater than the length of the second through hole 2211 in the second direction (that is, the protrusion 123 passes through the second through hole 2211 and then extends out of the second through hole 2211).

[0044] Fig. 9 is another schematic diagram of the housing of the electronic blood pressure meter according to an embodiment of the present application, showing a view of the housing viewed from the lower rear; Fig.10 is along Figure 2 A cross-sectional view taken along line CC'.

[0045] In the embodiments of the present application, Figure 3 , Figure 4 , Figure 7 , Fig. 9 and Fig.10 As shown, the wristband structure 20 may also have a positioning portion 23, which is arranged on the upper side surface F1 of the connecting portion 21, and extends upward from the upper side surface F1 of the connecting portion 21 along the first direction. The positioning portion 23, the second clamping portion 22 and the connecting portion 21 are integrally formed; the shell 11 is provided with a first groove portion 111 recessed toward the upper side, and the first groove portion 111 has a side wall portion 1111 perpendicular to the second direction. The positioning portion 23 is accommodated in the first groove portion 111 and is fixedly connected to the side wall portion 1111 of the first groove portion 111.

[0046] Therefore, by integrally forming the positioning portion 23, the second snap-fit ​​portion 22 and the coupling portion 21, the relative position relationship between the positioning portion 23 and the second snap-fit ​​portion 22 is fixed. In this way, the second snap-fit ​​portion 22 can be positioned in the second direction through the fixed connection between the positioning portion 23 and the side wall portion 1111, that is, the second snap-fit ​​portion 22 will not shift to the right.

[0047] In the embodiment of the present application, the fixed connection between the positioning portion 23 and the side wall portion 1111 can be achieved by screw positioning, but the present application is not limited to this, and the fixed connection between the positioning portion 23 and the side wall portion 1111 can also be achieved by other methods, such as bonding, etc.

[0048] In the embodiments of the present application, Figure 4 , Figure 5 and Figure 8 As shown, the second engaging portion 22 may further include: two spring sheet structures 222, the two spring sheet structures 222 are respectively arranged on two side surfaces F5 and F6 of the main body 221 in the third direction, the upper end E1 and the lower end E2 of each spring sheet structure 222 in the first direction are respectively fixedly connected to the main body 221, and each spring sheet structure 222 may include a first elastic portion 2221 located on the upper side and a second elastic portion 2222 located on the lower side and connected to the first elastic portion 2221 at an obtuse angle;

[0049] Among them, the surface of the second elastic portion 2222 away from the main body portion 221 is provided with a limiting portion 22221 formed in a multi-step shape, and the limiting portion 22221 includes a first limiting surface 22221a parallel to the first direction and a second limiting surface 22221b perpendicular to the first direction, the first limiting surface 22221a abuts against the inner surface of the first through hole 121 in the third direction, and the second limiting surface 22221b abuts against the upper surface F7 of the shell 11 in the first direction; that is, the first limiting surface 22221a of the limiting portion 22221 of the second elastic portion 2222 on the left side abuts against the third side 121c of the first through hole 121, and the first limiting surface 22221a of the limiting portion 22221 of the second elastic portion 2222 on the right side abuts against the fourth side 121d of the first through hole 121.

[0050] Therefore, the positioning of the second engaging portion 22 in the up-down direction and the left-right direction is further strengthened by the limiting function of the spring structure 222 included in the second engaging portion 22, so that the engaging between the second engaging portion 22 and the housing 11 can be further tightened.

[0051] In the embodiment of the present application, each spring structure 222 can be fixedly connected to the main body 221 by means of integral molding, but the present application is not limited thereto. For example, they can also be fixedly connected to the main body 221 by means of bonding or the like.

[0052] In the embodiments of the present application, Figure 8As shown, the upper end of each spring structure 222 is aligned with the upper end of the main body 221 (that is, the length of the spring structure 222 in the first direction is the same as the length of the main body 221 in the first direction), and the lower end of each spring structure 222 is aligned with the lower end of the main body 221, so that the plane where the left first elastic part 2221 is located and the side F5 of the main body 221 in the third direction form an angle θ, similarly, the plane where the right first elastic part 2221 is located and the side F6 of the main body 221 in the third direction also form an angle θ, and the angle θ can be greater than 12° and less than 16°, and preferably, the angle θ can be 14°.

[0053] In the embodiment of the present application, if the pressing force is greater than 45N, the user needs to use a larger force to insert the second locking portion 22 into the first through hole 121 (that is, it is more difficult to insert), and if the pressing force is less than 35N, the rebound force of the spring structure 222 may be insufficient to make the first limiting surface 22221a tightly abut against the inner surface of the first through hole 121 in the third direction. Therefore, the pressing force of the spring structure 222 when pressing the first through hole 121 is between 35N and 45N, which is a better pressing force.

[0054] Therefore, by limiting the angle θ, the pressing force of the spring structure 222 on the first through hole 121 can be guaranteed to be between 35N and 45N. In other words, the user can use a more comfortable force to insert the second locking portion 22 into the first through hole 121, thereby further improving the user experience. At the same time, the rebound force of the spring structure 222 can make the first limiting surface 22221a tightly abut against the inner surface of the first through hole 121 in the third direction.

[0055] In the embodiments of the present application, the above-mentioned implementation method illustrates the limitation of the angle θ when the upper end of each spring structure 222 is aligned with the upper end of the main body 221, but the present application is not limited to the upper end of each spring structure 222 being aligned with the upper end of the main body 221. For example, the length of the main body 221 in the first direction can be lengthened (for example, the main body 221 is extended upward), so that when the upper end of the spring structure 222 is not aligned with the upper end of the main body 221, the above-mentioned limitation of the angle θ can also be met, so that the pressing force of the spring structure 222 in the first pressure through hole 121 is guaranteed to be between 35N and 45N.

[0056] That is to say, in the embodiment of the present application, the angle θ is limited to a value between 35N and 45N when the spring structure 222 is pressed into the first pressure through hole 121 .

[0057] In the embodiments of the present application, Figure 8As shown, the second engaging portion 22 may further include an introduction portion 223, which is disposed on the upper side surface F8 of the main body 221 and extends upward from the upper side surface F8 of the main body 221. In other words, the length of the main body 221 of the second engaging portion 22 in the first direction may be appropriately lengthened. The introduction portion 223 may also be integrally formed with the main body 221, that is, the upper end of each spring structure 222 may also be aligned with the upper end of the introduction portion 223.

[0058] like Figure 5 and Figure 8 As shown, the length of the introduction portion 223 in the first direction is approximately 1 to 2 mm. Preferably, the length of the introduction portion 223 in the first direction is approximately 1.5 mm. The width W1 of the second engaging portion 22 along the third direction at the lower side surface of the introduction portion 223 is the same as the distance W2 between the third side 121c of the first through hole 121 and the fourth side 121d of the first through hole 121 in the third direction; that is, at a distance of approximately 1.5 mm from the upper side surface of the second engaging portion, the width W1 of the second engaging portion 22 in the third direction (including the thickness of the spring structure 222 in the third direction) is the same as the distance W2 between the third side 121c and the fourth side 121d of the first through hole 121 in the third direction.

[0059] Since the second engaging portion 22 is not subjected to force when it is inserted into the first through hole 121 of the first engaging portion 12 (i.e., in the initial stage of engagement between the first engaging portion 12 of the shell 11 and the second engaging portion 22 of the wristband structure 20), and the second engaging portion 22 begins to be subjected to force only after a portion of the second engaging portion 22 is inserted into the first engaging portion 12, by providing such an introduction portion 223 and the setting of W1=W2, when the second engaging portion 22 is inserted into the first through hole 121 of the first engaging portion 12, the introduction portion 223 first contacts the first through hole 121, and the outer surface of the second engaging portion 22 in the third direction can be just engaged with the inner diameter of the first through hole 121 in the third direction, so that the second engaging portion 22 is not easily skewed in the first through hole 121 when engaged with the first through hole 121, thus avoiding deviation and facilitating the engagement of the second engaging portion 22 in the positive direction.

[0060] In the embodiment of the present application, the length of the introduction portion 223 in the first direction may not be limited to 1 to 2 mm. The length of the introduction portion 223 in the first direction may be set according to different models of the sphygmomanometer, for example, according to the thickness of the shell and the length of the main body in the first direction.

[0061] In the embodiment of the present application, the main body 221 may be provided with a second groove 2212 that is recessed downward from the upper side surface F8 of the main body 221, and the second groove 2212 passes through the front side surface F3 and the rear side surface F4 of the main body 221 in the second direction; that is, the main body 221 is formed into a substantially H-shaped structure. Similarly, when an upwardly extending introduction portion 223 is provided on the upper side surface F8 of the main body 221, the second groove 2212 may be recessed downward from the upper side surface of the introduction portion 223 (such as Figure 4 and Figure 8 As shown), in this way, the introduction portion 223 is equivalent to being respectively arranged on the upper surface of the left side and the upper surface of the right side of the main body 221.

[0062] Thus, the wall thickness of the H-shaped main body 221 (or the main body 221 and the introduction part 223 ) in the third direction becomes thinner, so that when the spring structure 222 is pressed to insert it into the first through hole 121 , the H-shaped main body 221 is easy to deform and is convenient for insertion into the first through hole 121 .

[0063] In the embodiments of the present application, Figure 8 As shown, the distance D1 between the connection point P1 of the first elastic part 2221 and the second elastic part 2222 and the side surface of the main body 221 in the third direction in the third direction is greater than or equal to 1 mm. In other words, the spring structure 222 is formed as a bow-shaped spring, and the distance between the spring structure 222 and the side surface of the main body 221 in the third direction is at least 1 mm, so that the elastic deformation of the spring structure 222 can be guaranteed, and it is also convenient for the spring structure 222 to be inserted into the first through hole 121.

[0064] Fig.11 2 is a schematic diagram of the second engaging portion of an embodiment of the present application, showing a view of the second engaging portion when viewed from the left side.

[0065] In the embodiments of the present application, Fig.11 As shown, the width D2 of the spring structure 222 in the second direction is smaller than the thickness D3 of the main body 221 in the second direction, and the spring structure 222 can be arranged at the central position of the main body 221.

In this way, since the width D2 of the spring structure 222 is relatively small, the pressing force applied to the spring structure 222 does not need to be too large.

[0066] In the embodiment of the present application, the height of the main body 221 in the first direction can be approximately 6 mm, the length of the first side 121a and the second side 121b of the first through hole 121 in the third direction can be approximately 5.5 mm, the length of the third side 121c and the fourth side 121d of the first through hole 121 in the second direction can be approximately 5 mm, the length of the second through hole 2211 in the third direction can be approximately 2.5 mm, the height of the second through hole 2211 in the first direction can be approximately 1.1 mm, the maximum plate thickness of the spring structure 222 can be approximately 0.2 mm, the length of the first limiting surface 22221a of the limiting portion 22221 in the first direction is set in relation to the thickness of the shell 11, for example, can be greater than or equal to 0.3 mm, and the length of the second limiting surface 22221b of the limiting portion 22221 in the third direction can be greater than or equal to 0.2 mm.

[0067] In the embodiments of the present application, Figure 5 As shown, two first engaging parts 12 and two second engaging parts 22 may be provided, wherein one first engaging part 12 and the second engaging part 22 engaging therewith are provided on the left side, and one first engaging part 12 and the second engaging part 22 engaging therewith are provided on the right side. However, the number and position of the first engaging part 12 and the second engaging part 22 of the present application are not limited thereto.

[0068] In the embodiment of the present application, the above data is applicable to most types of electronic blood pressure monitors. In addition to these types of electronic blood pressure monitors, the dimensions of the first engaging portion 12 and the second engaging portion 22 can be adjusted based on the model.

[0069] The above only describes the structures related to the electronic blood pressure meter 1 in the embodiment of the present application. The present application is not limited thereto. The electronic blood pressure meter 1 may also include other conventional structures. For details, please refer to the relevant technology, and the description is omitted here.

[0070] According to this embodiment, by accommodating the protrusion 123 of the first engaging portion 12 in the second through hole 2211 of the main body 221 of the second engaging portion 22 and matching with the clearance therebetween, the housing 11 and the wristband structure 20 can be more tightly engaged in the up and down directions, and the joint between the two is less likely to loosen, thereby reducing the phenomenon of the air intake pipe being broken during repeated use.
