[0027] [First Embodiment]

[0028] Referring to Figures 1 to 5 Fig. 1, the present application provides a pulse reproduction mechanism 1 to reproduce a converted pulse signal as mechanical energy. In practical application, reference can be made to the inventor's granted Taiwan Patent No. TW I682765. As shown in Figure 1 Fig. 2, a wrist of a subject wears a pulse measurement device 9, which includes three sets of pulse measurement units 91, 92, 93. Each pulse measurement unit (91, 92, 93) can include a pressure pulse device, a pulse sensor, etc. The pulse measurement device 9 transmits pulse vibration information to a remote human-machine interface P1. After processing, the converted pulse signal is transmitted to a local human-machine interface P2. At the local end, three pulse reproduction mechanisms 1 are electrically connected to the local human-machine interface P2. The present application provides a pulse tactile feedback effect to the subject's fingers through the three pulse reproduction mechanisms 1.

[0029] As shown in Figures 2 to 5 Fig. 3, the present embodiment takes one pulse reproduction mechanism 1 as an example, which is described in detail as follows. Each pulse reproduction mechanism 1 includes a base 20, a pressure sensing unit 30, an energy conversion unit 40, a tactile feedback unit 50, and a pressure transmission member 60. Briefly, the present application can transmit the converted pulse vibration of the energy conversion unit 40 to the subject's fingers through the tactile feedback unit 50. On the other hand, the present application can also transmit the force of the subject's fingers pressing through the pressure transmission member 60 to the pressure sensing unit 30 to detect various finger pressing forces of the subject taking pulse, which is transmitted back to the pulse measurement device 9 for corresponding measurement of various pulses. The following describes each element in detail.

[0030] The base 20 forms a sensing area 230. Specifically, the base 20 has a base plate 23 and a pair of side walls 21, which are oppositely arranged on both sides of the base plate 23. The sensing area 230 is arranged on the base plate 23 and close to one end of the base plate 23. Specifically, the sensing area 230 is formed in a long and narrow groove shape on the top surface of the base plate 23, one end of which is in a circular groove shape, and the other end is in a rectangular groove shape extending to the end of the base plate 23 (as shown in Figure 3 and Figure 4The pressure sensing unit 30 is disposed in the sensing area 230. For example, the pressure sensing unit 30 of the present embodiment can be a piezoelectric pressure sensor having a circular sensing area 31 and two pin leads 32 extending outwardly from the sensing area 31. In this way, the pressure sensing unit 30 can detect the pressure applied by the finger of the subject and convert the pressure into a corresponding signal, which is transmitted to the pulse wave measuring device 9 (see FIG. 1) via the cable 10. Figure 1

[0031] In the present embodiment, the energy conversion unit 40 is disposed on the base 20 to convert the electrical energy of the pulse wave signal into kinetic energy. The number of energy conversion units 40 can be at least one, depending on the conditions that can be detected by a single energy conversion unit 40. Specifically, the energy conversion unit 40 can be a piezoelectric plate 41. One end of the piezoelectric plate 41 is connected to a cable to receive the pulse wave signal, and the other end (or vibration end) generates vibrations perpendicular to the piezoelectric plate 41. However, the present application is not limited thereto, and the energy conversion unit can be various sensing elements that convert the electrical energy of the pulse wave signal into kinetic energy.

[0032] More specifically, to secure the energy conversion unit 40, the base 20 of the present embodiment further includes a clamping member 22 that secures the energy conversion unit 40 above the bottom plate 23. The clamping member 22 of the present embodiment includes a pair of clamping blocks 220 and a pair of locking members 221. The pair of clamping blocks 220 are fixedly disposed on the inner sides of the pair of side walls 21, respectively. Specifically, the pair of locking members 221 pass through the pair of side walls 21 to secure the pair of clamping blocks 220 to the base 20. The clamping member 22 of the present embodiment clamps the piezoelectric plate 41 at a position approximately halfway between the two ends of the piezoelectric plate 41. However, the present application is not limited thereto, and the clamping member can clamp the end or the middle of the piezoelectric plate 41. In the present embodiment, the piezoelectric plate 41 is disposed between the pair of clamping blocks 220. As shown in FIG. 2, each clamping block 220 forms a clamping groove 2201, and the clamping member 22 can include a securing shaft 25 disposed at the clamping position of the piezoelectric plate 41. Figure 3 Figure 5 As shown in FIG. 2, the clamping blocks 220 are inclined with respect to the bottom plate 23 of the base 20. The locking members 221 of the present embodiment can be screws, etc. The present application is not limited thereto, and the number of clamping blocks and locking members can be at least one. Figure 3

[0033] ​​​The fixed shaft 25 of the embodiment is arranged between two ends of the piezoelectric plate 41, and functions as a fulcrum. Different force arms are formed according to the distance from the fixed shaft 25 to the vibration end, so that different amplitudes are generated. However, the fixed shaft can be omitted in the present application.

[0034] As shown in Figure 5 The energy conversion unit 40 further has a conducting block 43 fixed to one end of the piezoelectric plate 41, i.e. the vibration end. The conducting block 43 abuts against the bottom end of the touch bump 51. The conducting block 43 of the embodiment is substantially a rectangular cuboid, and forms a holding groove 430 for clamping the one end of the piezoelectric plate 41.

[0035] As shown in Figure 3 The touch feedback unit 50 has a touch bump 51 abutting against the energy conversion unit 40. The touch bump 51 can be made of rubber or silicone, and has a slightly spherical top end.

[0036] In the embodiment, the pressure conducting member 60 is adjacent to the touch feedback unit 50. The bottom of the pressure conducting member 60 is provided with a pressing portion 64 abutting against the pressure sensing unit 30. Specifically, the pressure conducting member 60 is in the shape of a square box and forms a receiving space 60S. The conducting block 43 is floatingly located in the receiving space 60S, i.e. does not contact the pressure conducting member 60. The pressure conducting member 60 has a top wall 61 and a bottom wall 62. The top wall 61 forms a lower through hole 610, and the touch bump 51 is exposed from the lower through hole 610. The conducting block 43 is located below the lower through hole 610. The pressing portion 64 of the embodiment protrudes downward from the bottom wall 62.

[0037] It is further explained that the touch feedback unit 50 further has a simulation sheet 52, which can be an artificial skin to provide a skin-like touch. The touch bump 51 is located in the middle of the simulation sheet 52. The top wall 61 of the pressure conducting member 60 protrudes a pair of limiting portions 65 on both sides thereof. The simulation sheet 52 is arranged in the pair of limiting portions 65, and forms an upper through hole 520 corresponding to the position of the lower through hole 610. However, the present application is not limited thereto, and the simulation sheet can be relatively thin and does not have any through hole.

[0038] In the embodiment, each side of the pressure conducting member 60 is provided with a convex rib 66. Each of the pair of side walls 21 of the base 20 has a guide rail 26, and the convex rib 66 is slidably arranged in the guide rail 26.

[0039] The pulse reproduction mechanism 1 of this embodiment may further include an outer shell 80, which covers the base 20 and forms an external through hole 81. The tactile bump 51 of the tactile feedback unit 50 is exposed in the external through hole 81.

[0040] [Second Embodiment]

[0041] like Figure 6 As shown, the difference between this embodiment and the previous embodiment is that the pulse reproduction mechanism 1a includes multiple energy conversion units 40, and the multiple energy conversion units 40 can be piezoelectric plates 41 of the same specification. The multiple piezoelectric plates 41 of the multiple energy conversion units 40 are arranged in parallel, and multiple fixed shafts 25 are arranged along an oblique line and fixed to the base 20 by clamping member 22a. The clamping member 22a is similar to the previous embodiment, and a pair of clamping blocks 220 are provided with multiple clamping grooves 2201 and are fixed between the pair of sidewalls 21.

[0042] The conductive block 45 is stepped and has multiple retaining grooves 450, which face the multiple energy conversion units 40. The ends of the multiple piezoelectric plates 41 are respectively fixed in the multiple retaining grooves 450 of the conductive block 45.

[0043] In this embodiment, the vibrating ends of the multiple piezoelectric plates 41 are arranged along a diagonal line and fixed in a staggered manner within the multiple retaining grooves 450 of the conductive block 45. In order to accurately transmit the vibration force to the tactile protrusion 51, the number of piezoelectric plates 41 can be multiple, with multiple piezoelectric plates 41 vibrating together, and the vibrating ends of the multiple piezoelectric plates 41 being evenly distributed directly below the tactile protrusion 51.

[0044] The advantage of this embodiment is that the power of multiple energy conversion units 40 can be stacked to provide a stronger vibration, making the pulse vibration more obvious.

[0045] [Third Embodiment]

[0046] Please see Figure 7The difference between the present embodiment and the above-mentioned embodiments is that the pulse reproduction mechanism 1b comprises a plurality of energy conversion units 40, and the two ends of the plurality of piezoelectric plates 41 are aligned with each other and arranged in parallel. The clamping member 22b is arranged opposite to the conducting block 45b at the two ends of the plurality of energy conversion units 40, which can be referred to as the fixed end and the vibrating end. The clamping member 22b has only one clamping block 220, and the bottom of the clamping block 220 is provided with a locking member 221 to be fixed to the bottom plate 23 of the base 20. The clamping block 220 has a plurality of clamping grooves 2201 for respectively holding the fixed ends of the plurality of piezoelectric plates 41, and the conducting block 45b has a plurality of holding grooves 450 for respectively holding the vibrating ends of the plurality of piezoelectric plates 41. The present embodiment omits the fixing shaft.

[0047] The thickness of the simulation sheet 52b of the present embodiment is thinner than that of the above-mentioned embodiments, which can not affect the touch bump 51 and does not have any through hole.

[0048] [Advantages of the embodiments]

[0049] One of the advantages of the present application is that the pulse reproduction mechanism provided by the present application can transmit the pulse vibration converted by the energy conversion unit 40 to the finger of the measurer through the tactile feedback unit 50. On the other hand, the present application can also transmit the force applied by the measurer to the pressure sensing unit 30 through the pressure conducting member 60, so as to detect various finger forces applied by the measurer when taking the pulse, and transmit the detected finger forces to the pulse measuring device 9, so that the pulse measuring device 9 can correspondingly measure various pulses.

[0050] The above-mentioned disclosure is only the preferred and feasible embodiment of the present application, and any equivalent changes and modifications made according to the claims of the present application shall be within the scope of the present application.
