[0001] The present application relates to the field of key technologies, and in particular, to a side-by-side key and a sphygmomanometer. Background Art

[0002] A sphygmomanometer used in medical treatment is provided with a plurality of plastic keys, and the plastic keys and the electrical keys on a printed circuit board assembly realize linkage control through mechanical fit.

[0003] However, the bottom of the existing plastic keys usually adopts a "cross" structure. Due to deviations in actual manufacturing and assembly of the plastic keys, it is easy to cause that the upper and lower keys cannot completely correspond to the same vertical axis. When the plastic key is pressed, if the electrical switch on the printed circuit board assembly cannot be accurately triggered and the rebound force thereof is obtained, sliding may occur between the upper and lower plastic parts, resulting in key failure, and finally causing the entire device to fail to work normally.

[0004] Therefore, there are defects and deficiencies in the prior art, which need further improvement and development. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the purpose of the present application is to provide a side-by-side key and a sphygmomanometer, aiming at solving the problem that the side-by-side keys in the prior art and the keys on the printed circuit board assembly are prone to failure due to assembly deviation.

[0006] The technical solution adopted by the present application to solve the technical problem is as follows: a side-by-side key and a sphygmomanometer, which are used for controlling the sphygmomanometer, comprising: a plurality of side-by-side keycaps, each of which is provided with an accommodating groove; a pressing part, which is fixedly arranged in the accommodating groove; the pressing part is used for triggering an electrical switch on a printed circuit board assembly of the sphygmomanometer; wherein the pressing part is provided with a supporting cylinder and a plurality of supporting plates; the plurality of supporting plates are fixedly arranged around the supporting cylinder at uniform intervals.

[0022] Please refer to the following: Figures 1 to 4 The first embodiment of this application provides a side-by-side button 10 for controlling a blood pressure monitor. The side-by-side button 10 includes: a plurality of side-by-side keycaps 11, a pressing part 12, an anti-slip ring 1221, a fixing member 13, and a circular button 14. The plurality of side-by-side keycaps 11 are for direct pressing operation by the user. Each side-by-side keycap 11 is provided with a receiving groove 111 for accommodating the pressing part 12. The pressing part 12 is fixedly disposed in the receiving groove 111, and its function is to transmit the force to the electrical switch on the printed circuit board assembly of the blood pressure monitor when the user presses the keycap, thereby triggering the function.

[0023] The pressing part 12 includes a supporting cylinder 121 and several supporting plates 122. The supporting plates 122 are evenly spaced and fixedly arranged around the supporting cylinder 121, stabilizing the pressing direction and maintaining uniform force on the structure. Specifically, to improve anti-slip performance, an anti-slip ring 1221 is provided at the end of each supporting plate 122 away from the receiving groove 111. The anti-slip ring 1221 is embedded in the supporting plate 122, generating friction between the components and effectively preventing slippage of the upper and lower structures during pressing. To adapt to molding processes and functional requirements, the end face area of ​​the supporting plates 122 near the receiving groove 111 is larger than the end face area away from the receiving groove 111, and the number of supporting plates 122 is greater than four, preferably eight, arranged in a star shape. This increases the contact area between the two buttons, and since they are not on the same axis, it also enhances the button's rebound stability and trigger reliability. The supporting plates 122 can be right-angled, trapezoidal, or arc-shaped to meet the needs of different structural strengths and spatial arrangements. A plurality of keycaps 11 arranged side-by-side include a left keycap 112, a middle keycap 113, and a right keycap 114, which are spaced apart and fixedly connected together by a fastener 13. The fastener 13 includes a straight section 131 and a left fold section 132, a middle fold section 133, and a right fold section 134 connecting the three keycaps. The left keycap 112, the middle keycap 113, and the right keycap 114 are respectively connected to the straight section 131 through their corresponding fold sections, forming a stable integrated side-by-side structure to prevent triggering abnormalities caused by the displacement of a single keycap. In addition, the straight section 131 is provided with a first fixing hole 1311, a second fixing hole 1312, and a third fixing hole 1313, which are located between or at the ends of each fold section, for mounting and fixing with other structural components, such as the housing or bracket of a blood pressure monitor, further improving the stability and installation accuracy of the entire assembly. On one side of several parallel keycaps 11, there is also a circular button 14, which is also provided with a pressing part 12 for independently triggering the electrical switch on the printed circuit board assembly, further expanding the control function of the button and meeting a variety of operation needs.

[0024] Please refer to the following: Figures 1 to 2In some embodiments, the side-by-side buttons 10 include a pressing part 12 and a plurality of side-by-side keycaps 11, each of which is provided with a receiving groove 111; the pressing part 12 is fixedly disposed in the receiving groove 111; the pressing part 12 is used to trigger an electrical switch on the printed circuit board assembly of the blood pressure monitor; wherein, the pressing part 12 is provided with a supporting cylinder 121 and a plurality of supporting plates 122; the plurality of supporting plates 122 are evenly spaced and fixedly disposed around the supporting cylinder 121. Therefore, by providing a plurality of side-by-side keycaps 11, a pressing part 12, a supporting cylinder 121, and a plurality of supporting plates 122 evenly spaced around the supporting cylinder 121, the problem of button failure caused by assembly misalignment between the side-by-side buttons 10 and the electrical switch on the printed circuit board assembly in the prior art can be effectively solved. Specifically, the pressing part 12, through the support cylinder 121 and several surrounding support plates 122, stabilizes the structure and accurately transmits the force to the electrical switch on the printed circuit board assembly when the user presses the side-by-side keycaps 11. The support plates 122 provide directional guidance and stability, preventing bias or lateral slippage, thereby significantly improving the triggering reliability of the buttons and the overall stability of the blood pressure monitor.

[0025] Please refer to the following: Figure 3 In some embodiments, an anti-slip ring 1221 is fixedly provided at one end of each of the support plates 122 away from the receiving groove 111, and the anti-slip ring 1221 is embedded in the support plates 122. Anti-slip protrusions may be provided on the anti-slip ring 1221; thus, by providing the anti-slip ring 1221 at one end of each of the support plates 122 away from the receiving groove 111 and embedding the anti-slip ring 1221 in the support plate 122, effective friction can be formed between the pressing part 12 and the printed circuit board assembly, thereby preventing longitudinal slippage during the pressing process. This greatly enhances the stability of the cooperation between the electrical switch and the parallel buttons 10, ensuring that the force transmission process is not deviated due to surface smoothness or tolerance issues, and improving the operating accuracy and long-term reliability of the blood pressure monitor.

[0026] Please refer to the following: Figure 2 In some embodiments, the end face area of ​​the plurality of support plates 122 near the receiving groove 111 is larger than the end face area of ​​the plurality of support plates 122 away from the receiving groove 111, and the number of support plates 122 is greater than four. Furthermore, by setting the end face area of ​​the plurality of support plates 122 near the receiving groove 111 to be larger than the end face area away from the receiving groove 111, it helps to enhance the rebound performance and deformation control capability of the support plates 122 during the pressing process. At the same time, setting the number of support plates 122 to more than four significantly improves the overall support strength and force uniformity of the pressing part 12. This helps to reduce structural bias, further enhances the stability and response consistency of the pressing process, and improves the user's operating experience.

[0027] Please refer to the following: Figure 2 In some embodiments, the support plates 122 are configured as right angles, trapezoids, or arcs. Furthermore, by configuring the support plates 122 as right angles, trapezoids, or arcs, they can be flexibly adapted to the internal space of the blood pressure monitor and the button layout requirements. Different shapes of support plates 122 provide stability while also adapting to molding processes and optimizing the mechanical structure. Specifically, trapezoidal support plates 122 can enhance vertical support, while arc-shaped structures can alleviate areas of concentrated stress and improve the service life of the pressing part 12.

[0028] Please refer to the following: Figure 1 In some embodiments, the plurality of side-by-side keycaps 11 include a left keycap 112, a middle keycap 113, and a right keycap 114, which are spaced apart. Furthermore, by clearly distinguishing the plurality of side-by-side keycaps 11 into left keycaps 112, middle keycaps 113, and right keycaps 114, and setting them in an interleaved state, it helps to improve the recognizability and pressing convenience of the keys, and prevents accidental key presses. Maintaining an appropriate distance between the three keycaps avoids structural interference and provides the necessary space for the subsequent installation of the fixing component 13.

[0029] Please refer to the following: Figures 3 to 4 In some embodiments, the side-by-side buttons 10 further include a fixing member 13, which is used to fix the left cap 112, the middle cap 113, and the right cap 114 together. The fixing member 13 is introduced to fix the left cap 112, the middle cap 113, and the right cap 114 together as a whole, forming a stable, integrated side-by-side structure, effectively preventing individual keycaps from shifting due to structural loosening or external interference. The fixing member 13 enhances the structural coordination between the keycaps, ensuring high consistency throughout the button assembly during assembly and use, improving the feel and reliability of the blood pressure monitor during operation.

[0030] Please refer to the following: Figures 3 to 4In some embodiments, the fastener 13 includes: a straight segment 131, a left-folded segment 132, a middle-folded segment 133, and a right-folded segment 134; one end of the left-folded segment is fixedly connected to the left cap 112; the other end of the left-folded segment is fixedly connected to the straight segment 131; one end of the middle-folded segment is fixedly connected to the middle cap 113; the other end of the middle-folded segment 133 is fixedly connected to the straight segment 131; one end of the right-folded segment is fixedly connected to the right cap 114; and the other end of the right-folded segment 134 is fixedly connected to the straight segment 131. This structural design, including the straight segment 131, left-folded segment 132, middle-folded segment 133, and right-folded segment 134, allows the left cap 112, middle cap 113, and right cap 114 to be effectively connected by folds and straight segments 131, forming a connection method with a reasonable spatial layout and balanced force. This facilitates modular production and rapid assembly, improves assembly efficiency, and reduces manufacturing error risks.

[0031] Please refer to the following: Figure 4 In some embodiments, the straight segment 131 is provided with a first fixing hole 1311, a second fixing hole 1312, and a third fixing hole 1313. The first fixing hole 1311 is located between the left fold segment 132 and the middle fold segment 133, the second fixing hole 1312 is located between the right fold segment 134 and the middle fold segment 133, and the third fixing hole 1313 is located at the end of the straight segment 131. Furthermore, by providing the first fixing hole 1311, the second fixing hole 1312, and the third fixing hole 1313 on the straight segment 131, and by rationally arranging them according to the fold segment and end positions, it is convenient to accurately install the entire parallel button 10 assembly onto the blood pressure monitor's housing, bracket, or internal frame. This prevents the assembly from shifting or loosening during long-term use, enhancing the device's durability and product quality consistency.

[0032] Please refer to the following: Figure 1 In some embodiments, the side-by-side buttons 10 further include a circular button 14, which is disposed on one side of the plurality of side-by-side keycaps 11 and has a pressing part 12.

[0033] A second embodiment of this application provides a blood pressure monitor including the side-by-side buttons described above. Integrating these side-by-side buttons into the blood pressure monitor ensures higher structural integration, better user operation, and stronger reliability of function triggering. By introducing an integrated, highly stable, and adaptable side-by-side button structure, the blood pressure monitor is less prone to failure during long-term use, extending product lifespan, resolving after-sales complaints related to mass production, improving customer reputation, and further enhancing overall product quality and market competitiveness.

[0034] In summary, this application provides a side-by-side button and a blood pressure monitor. The side-by-side button includes: a plurality of side-by-side keycaps, each of which has a receiving groove; a pressing part, which is fixedly disposed in the receiving groove; the pressing part is used to trigger an electrical switch on the printed circuit board assembly of the blood pressure monitor; wherein the pressing part is provided with a supporting cylinder and a plurality of supporting plates; the plurality of supporting plates are evenly spaced and fixedly disposed around the supporting cylinder.
