Definitions

  • the invention relates to the field of electronic devices, and in particular organs making it possible to control functions of an electronic device.
  • the invention relates to a control module of an electronic device adapted to resist shocks.
  • the present invention is particularly suitable for portable electronic devices, for example electronic watches.
  • the control elements of electronic devices are generally made up of switches adapted to authorize or prohibit the passage of a current making it possible, for example, to transmit a setpoint for carrying out a function.
  • the switches are designed so as to occupy a rest position and a connection position in at least one of which they are driven under the action of a user.
  • switches comprising a flexible membrane covering an elastic blade adapted to connect connection terminals together when requested by a user, that is to say when it is constrained, and to prohibit any connection between the terminals when it is at rest.
  • Electronic devices often include a pusher adapted to be manipulated by the user so as to come into contact with the flexible membrane of the switch, by means of a striker, in order to deform the elastic blade in its connection position.
  • the elastic blade When the electronic device suffers an impact at the level of the pusher, the elastic blade is likely to deform plastically under the effect of the forces applied to it, and consequently, it risks presenting irreversible damage.
  • a solution to avoid this problem consists of increasing the dimensions of the contact surface of the striker so that it distributes the transmitted forces as much as possible so as to reduce the pressure to which the elastic blade is subjected.
  • this solution may not be able to be implemented, for example due to manufacturing constraints.
  • Another solution consists of providing an extra thickness in the flexible film.
  • This film is generally made of silicone, this extra thickness is designed to deform elastically during an impact in order to absorb the forces.
  • the switch can therefore advantageously be a standard component available commercially.
  • the invention may also include one or more of the following characteristics, taken individually or in all technically possible combinations.
  • the shock absorber is fixed on a bearing surface of the striker element so as to apply pressure on the switch when the striker drives the switch in the connected state or in the state rest.
  • the shock absorber has the shape of a disc.
  • the shock absorber is intended to be arranged between a structure of the watch movement and the switch, in the extension of the direction of travel of the pusher.
  • the switch comprises a frame against which the shock absorber is arranged to rest so that said switch is interposed between the striker element and said shock absorber.
  • the switch comprises connection terminals and an elastic blade fixed to the frame, the elastic blade being moved into a connection position in which it generates contact between the connection terminals when the switch is in the connection state, and being moved into a rest state in which it prohibits contact between the connection terminals when the switch is in the rest state, the damper being arranged against at least one of the terminals connection so that the latter is interposed between the shock absorber and the striker element.
  • the pusher comprises a pusher head to which is connected a pusher rod slidably engaged in a guide tube and comprising a free end to which the striker element is fixed, the pusher comprising an interposed spring between the pusher head and the guide tube so as to force the pusher to move towards a rest position.
  • the striker element comprises a body of substantially cylindrical shape comprising a radial dimension extending in a direction orthogonal to the direction of movement of the pusher, said radial dimension being less than the external diameter of one end of the guide tube at which it is arranged.
  • the present invention relates to a watch comprising a box in which an electronic watch movement is housed, the watch being characterized in that the latter comprises a control module as described previously, the pusher being engaged through a middle part with which the box is equipped and the switch being fixed to a structure of the watch movement.
  • the invention is applied to the field of watchmaking.
  • the invention relates to a control module 10 here arranged in an electronic watch movement housed in a case of a watch, provided with a middle part 20, and intended for controlling a function upon request, for example an user.
  • the control module 10 comprises a pusher 11 movable in translation in a direction AA, intended to be activated by the user.
  • the pusher 11 is engaged through the middle part 20 in order to be accessible to the user.
  • the pusher can be mobile in rotation or more generally can be animated by any type of movement.
  • the control module 10 further comprises a switch 12 intended to be actuated by a user upon request of the pusher 11.
  • the switch 12 is adapted to occupy a connected state and a rest state, the pusher 11 being configured to , when it activates said switch 12, causing it to enter one or other of these states.
  • the switch 12 may comprise a frame 120 to which are fixed an elastic blade 121 made of electrically conductive material and connection terminals 122 and 123.
  • the switch 12 may include a connection terminal called "central terminal" 122 arranged in the direction of travel of the pusher 11, that is to say in alignment with the direction AA, and one or more peripheral terminals 123.
  • the elastic blade 121 is configured to occupy, when the pusher 11 is requested by the user, a connection position in which it generates a contact between the central terminal 122 and the peripheral terminal(s) 123.
  • the elastic blade 121 when the user presses the pusher 11, the latter applies pressure on the elastic blade 121, so as to deform it in an unstable flat position in which it is in contact with all the central 122 and peripheral terminals 123
  • the elastic blade 121 is also configured to occupy, when the pusher 11 is not requested by the user, a stable rest position, in which it prevents contact between the central terminals 122 and peripheral terminals 123.
  • the elastic blade 121 when in this position, can be curved so as to be pre-stressed to present elastic characteristics.
  • the switch 12 can also include a flexible membrane 124 covering the elastic blade 121, on which the pusher 11 is intended to press when requested.
  • this flexible membrane 124 is not essential to the invention.
  • the pusher 11 comprises a pusher head 110 extending outside the middle part 20 and intended to be manipulated by the user.
  • the pusher 11 also comprises a striker element 111 connected to the pusher head 110 via a pusher rod 112 slidably engaged in a guide tube 113 fixed in a through opening of the middle part 20.
  • the The striker element 111 is screwed into the pusher rod 112, or is fixed by any means suitable to those skilled in the art.
  • the guide tube 113 comprises, at a first end, a first portion through which it is engaged in the through opening of the middle part 20, and comprises, at a second end, a second portion having a diameter exterior larger than that of the first portion so as to form a shoulder with the latter. As shown in the figure 1 , the guide tube 113 is arranged to rest against the middle part 20 via this shoulder.
  • the pusher 11 comprises a spring 114 working in compression, interposed between the pusher head 110 and the shoulder of the guide tube 113 so as to force the pusher 11 to move into a rest position.
  • the striker element 111 rests against the first end of the guide tube 113 when the pusher 11 occupies its rest position.
  • the striker element 111 comprises a body of substantially cylindrical shape comprising a radial dimension extending in a direction orthogonal to the direction AA, said radial dimension being advantageously less than the external diameter of the first portion of the guide tube 113. This characteristic allows to facilitate the assembly of the striker element 111 on the pusher rod 112, insofar as it can be carried out before fixing the pusher 11 to the middle part 20 of the watch, that is to say before its engagement in the through opening of said middle part 20.
  • the body of the striker element 111 is provided with a bearing surface intended to apply, directly or indirectly, pressure on the elastic blade 121 when the pusher 11 is requested by the user, in order to cause its deformation until it occupies the connection position.
  • the control module 10 comprises a shock absorber 116 configured to absorb part of the forces involved when the pusher 11 actuates the switch 12, by deforming elastically, at least when said forces are greater than a predetermined threshold.
  • the shock absorber 116 is therefore made of an elastically deformable material, such as an elastomer, or has an elastically deformable structure, such as a compression spring.
  • the shock absorber 116 is arranged on the support surface so as to be forced in compression against the switch when the striker drives the switch 12 in the connected state or in the rest state.
  • the damper 116 applies pressure on the switch 12 in order to drive it into the connected state or into the rest state.
  • the damper 116 is preferably in the shape of a disc of an appropriate thickness to absorb a significant part of the forces involved while transmitting another part of these forces to the switch 12 for the change state.
  • the shock absorber 116 is arranged between the structure 21 of the watch movement and the switch 12, in the extension of direction AA; the switch 12 is thus interposed between the shock absorber 116 and the pusher 11.
  • the shock absorber 116 is arranged at the rear of the switch 12, against it, if we consider that the front of the switch 12 is opposite the pusher 11.
  • the switch 12 would be able to transmit part of these forces by moving or by locally deforming slightly in the shock absorber 116 which would absorb the part of the forces transmitted by the switch 12.
