Definitions

  • the present invention relates to a timepiece of the wristwatch type with capacitive touch zones comprising a battery door closed by an electrically conductive battery cover. More specifically, the present invention relates to such a watch comprising a battery door closed by an electrically conductive cover for improving the operation of the watch.
  • a capacitive touch zone wristwatch includes, in particular, a watch glass made of an organic or mineral transparent material disposed over a time indicating device.
  • the time indication device may be of the analog type. In this case, it is formed by a dial above which eg hour and minute hands move.
  • the time indicating device may also be of the digital type. In this case, it comprises a display cell whose optical properties are modified by applying a voltage or an appropriate electric current.
  • To form the tactile zones it is possible, for example, to structure on the face of the ice opposite the device for indicating the time electrodes made of a transparent conductive material such as tin-indium oxide, a better material. known under its name Anglo-Saxon indium-tin oxide or ITO.
  • the tactile zones form, with the air from which they are separated by the watch glass, the two plates of a capacitor which has a certain value of capacitance.
  • This capacity value is fixed by the sum of the various parasitic capacitances towards the mass of the electronic system seen by an electrode forming a tactile zone.
  • This capacity value will be modified when the user places his finger on the outer surface of the ice, opposite the electrode forming the selected touch zone. The effect of the finger is added to the parasitic capacitances and thus modifies the total capacity seen by the electronic control system of the watch.
  • the electronic control system housed in the watch case will detect this variation of capacity and deduce the corresponding instruction. In response to the introduction of this data, the electronic control circuit will perform the required operations.
  • the detection by the electronic control circuit of the variation of the capacitance of the tactile zones must be done as precisely as possible.
  • the variation in the capacity induced by the user is very low compared to the value of the parasitic capacitances and is therefore difficult to detect.
  • the detection sensitivity of the electronic control circuit must be greater and the detection threshold is closer to the noise level generated by the operation of the electronic control circuit. The electronic control circuit may therefore be triggered inadvertently and perform operations not desired by the user, which may for example disrupt the functions of the watch.
  • the present invention aims to overcome the aforementioned drawbacks as well as others by providing a capacitive type touch zone wristwatch comprising an electrically conductive battery cover making it possible to fix the detection system to the same electrical potential. and the wearer of the watch.
  • the present invention relates to a capacitive-type touch-zone wristwatch comprising a box made of a non-electrically conductive material, this box comprising a battery door in which a battery is housed and which is closed by an electrically conductive battery cover, characterized in that the electrically conductive battery cover is mounted on the watch case with the interposition of an electrically conductive seal between the battery cover and an electrode of the battery.
  • the present invention provides a wristwatch whose capacitive type touch zones are brought to the same electrical potential, which not only avoids fluctuations in the value of the capacity but also and especially ensure correct operation of the watch. Indeed, thanks to the presence of the conductive gasket of electricity, when the user puts his finger on the ice of the watch, it forms a closed loop between the finger of the user, the watch glass, the tactile zone opposite which the user's finger is placed, the printed circuit board on which the electronic control circuit of the tactile zones is mounted, the battery, the battery cover with which the battery is in contact via the seal and the wrist of the user with whom the battery cover is in contact.
  • the present invention proceeds from the general inventive idea of equipping the battery door with a seal made of an electrically conductive material such as an elastomeric material loaded with conductive particles so that when the user of the watch puts a finger on the ice of the watch, all the components of the watch involved in the detection of the capacitance variation are brought to the same electrical potential. It is thus possible to fix the detection system and the wearer of the watch at the same electrical potential, which makes it possible to significantly improve the additional capacitive effect induced by the user's finger and thus to optimize the variation of the value of the capacity seen by the detection system to ensure reliable operation of the watch.
  • an electrically conductive material such as an elastomeric material loaded with conductive particles
  • FIG. 1 The single figure appended to the present patent application is a schematic cross-sectional view of a capacitive-type touch-zone wristwatch according to the invention.
  • this watch comprises a transparent ice 2 made of an organic or mineral material.
  • This ice covers an analog time display device 4 comprising a dial 6 above which move an hour hand 8 and a minute hand 10.
  • On the face 12 of the watch glass 2 opposite the time display device 4 is structured at least one electrode forming a touch zone 14.
  • This touch zone 14 is made of a transparent electrically conductive material such as tin-indium oxide better known under the name Anglo-Saxon indium-tin oxide or ITO.
  • the touch zone 14 forms with the air from which it is separated by the watch glass 2 the two plates of a capacitor C1 which has a determined capacitance value.
  • This value of external capacitance C1 is formed by the left forearm around which the user has fixed his watch, the trunk of the user, his right forearm, the right hand and finally the finger 16 of the user. .
  • the value of the capacitor C1 is modified when the user places his finger 16 on the watch glass 2, next to the touch zone 14.
  • This touch zone 14 is connected to a control integrated circuit 18 by means of a connector 20 which extends vertically between the watch glass 2 and a printed circuit support 22 on which the integrated control circuit 18 is mounted.
  • the connector 20 is a "zébra" type connector which conducts electricity in the only direction vertical.
  • the housing plays the role of an electrically insulating element and prevents the electric loop between the finger, the various components involved in the detection of the capacitance variation of the touch zone and the wrist of the user closes on the finger of the latter.
  • the various components playing a role in the detection of capacitance variation are at floating potentials and the additional capacitive effect induced by the finger of the user is difficult to discern by the detection system.
  • one solution would be to charge the plastic with conductive particles. In this case, however, the resulting plastic material would be dark in color and the designer would enjoy no freedom in choosing the color of the watch case.
  • the box 24 of the watch 1 comprises a battery door 26 in which is housed a battery 28.
  • This battery door 26 is closed by a lid 30 which is electrically conductive with the interposition of a gasket.
  • sealing 32 made of an electrically conductive material between the electrically conductive cover 30 and the battery 28.
  • This seal 32 which seals the battery door 26 also ensures the continuity of the electrical conduction between the one of the poles of the battery 28 and the cover 30 conducting electricity.
  • This seal 32 may for example be made of an elastomeric material loaded with conductive particles.
  • the electrical contact between the battery cover 30 and the battery 28 can be further improved by arranging a layer of conductive fat between these two elements.
  • the other pole of the battery 28 is connected to the printed circuit support 22 for supplying the control integrated circuit 18 and the touch zone 14.
  • the electrically conductive gasket 32 serves to close a loop 34 between the user's finger 16 placed on the window 2 of the watch 1, the window 2, the touch zone 14, the integrated circuit 18, the battery 28, the seal 32, the battery cover 30 and the wrist of the user 36.
  • a capacitance C2 is thus formed between the wrist of the user 36, the battery cover 30, the seal 32, the battery 28, the printed circuit support 22, the electrical connector 20, the touch zone 14 and the ice 2 of the watch 1.
