  By the way, there is a demand for the pressure type input device to adjust the sensor sensitivity of the load sensor according to the product specifications of the electronic device, the mounting position with respect to the electronic device, or according to various uses of the electronic device. For example, high sensor sensitivity is required when a load sensor is disposed inside the housing, but high sensor sensitivity is not required when a load sensor is disposed outside the housing. However, the above-described conventional pressing type input device cannot adjust the sensor sensitivity because the pressing load acts directly on the load sensor.

  Further, in the above-described conventional press-type input device, since the pressing load of the touch screen is directly applied to the load sensor, the load sensor may be damaged when a large load is applied. In particular, when a piezoelectric ceramic is used for the load sensor, there is a problem that it is easily damaged.

  The present invention has been made in view of the above points, and provides a press-type input device that can prevent damage to a load sensor even when an overload is applied, and can easily adjust the sensor sensitivity of the load sensor. For the purpose.

The press-type input device of the present invention includes a load sensor that outputs a signal corresponding to an operation load from an operation member, and a contact member that extends from one end to which the operation load is applied and that contacts the load sensor. A cantilever spring extending along the extending direction of the contact member and generating an initial load on the load sensor via the other end of the contact member, and the contact member can be swung A support member that supports and applies a force in a direction to reduce an initial load of the load sensor to the other end side of the contact member by an operation load applied to one end side of the contact member; The abutting member is supported by the support member on both sides along the extending direction of the cantilever spring, the cantilever spring extends from the support member, and the load sensor extends in the operation direction of the operation member. It is arranged with the detection surface facing, and the contact member is on one end side Opposite to the operation member, the other end side is formed in a long shape facing the detection surface of the load sensor, an opening is formed between one end side and the other end side, A locking portion for locking the free end side of the cantilever spring extending into the opening is provided to extend from the other end side into the opening, and the free end side of the cantilever spring is the locking portion. When the cantilever spring is engaged with the load sensor, the cantilever spring attracts the other end side of the contact member to the load sensor side to generate an initial load . In the above configuration, the operation member, the contact member, and the support member are provided so as to overlap the contact member between the operation member and the support member, and the locking portion is the support It can be bent toward the member.

  According to this configuration, since the initial load acting on the load sensor due to the operation load from the operation member is reduced, the load sensor is prevented from being damaged even if an overload is applied to the operation member. Further, since the contact member is supported by the support member on both sides along the extending direction of the cantilever spring, the installation range of the fulcrum where the contact member is supported by the support member by the cantilever spring is limited. There is nothing. Further, in the contact member, the sensor sensitivity of the load sensor can be adjusted by changing the distance between the force point and the fulcrum to which the operation load is applied and the distance between the action point contacting the load sensor and the fulcrum. In this case, since the installation range of the fulcrum is not limited to the cantilever spring, the degree of freedom of installation of the fulcrum is high, and the sensor sensitivity of the load sensor can be adjusted in a wide range.

Further, in the press-type input device according to the present invention, a pair of protrusions protruding from the contact member toward the support member are provided on the contact member on both sides along the extending direction of the cantilever spring. The pair of projecting portions are configured as fulcrums on one end side where the operation load of the contact member is applied and on the other end side which contacts the load sensor side, and supports the contact member in a swingable manner. It is characterized by that .

According to this configuration, the contact member can be swingably supported with respect to the support member with a simple configuration.

  According to the present invention, even when an overload is applied, the load sensor can be prevented from being damaged, and the sensor sensitivity of the load sensor can be adjusted.

  Hereinafter, the present embodiment will be described in detail with reference to the accompanying drawings. In addition, below, the press-type input device attached to a liquid crystal display is demonstrated. However, the application target of the press-type input device according to the present embodiment is not limited to this, and can be changed as appropriate.

  With reference to FIG. 1 and FIG. 2, the whole structure of a press-type input device is demonstrated. FIG. 1 is a perspective view of a press-type input device according to the present embodiment. FIG. 2 is an exploded perspective view of the press-type input device according to the present embodiment.

  1 and 2 are arranged at predetermined locations on the back surface of an operation panel (not shown) provided in an electronic device, at least at one location, or at four corners, and can apply an operation load from the operation panel. It is configured to receive. The press-type input device 1 has a long U-shaped support member 2 having a substantially U-shaped cross-sectional view (a groove shape with an open top surface). A cantilever spring 14 is formed on the bottom plate portion 11 of the support member 2 together with the opening 13. A flexible substrate 3 is attached to the back surface of the support member 2, and the load sensor 4 on which the flexible substrate 3 is arranged protrudes upward through the opening 13 of the support member 2. A contact plate 5 is attached to the support member 2 so as to cover the opened upper surface.

  The abutting plate 5 is formed in an elongated shape with a substantially inverted U shape (a groove shape with an open bottom surface) when viewed in cross section. The abutting plate 5 abuts against the operation panel at one end and contacts the load sensor 4 at the other end. Touched. In this case, the other end side of the contact plate 5 is attracted to the load sensor 4 by a cantilever spring 14 provided on the support member 2, and an initial load is applied to the load sensor 4. A midway portion of the contact plate 5 in the longitudinal direction is supported by the bottom plate portion 11 of the support member 2 via a pair of protrusions 33 so as to be swingable. The contact plate 5 receives an operation load from the operation panel on one end side, and applies a force in the opposite direction to the initial load acting on the load sensor 4 with the swing fulcrum as a center.

  In the press input device 1 according to the present embodiment, the operation load from the operation panel acts so as to push back the cantilever spring 14, and the initial load acting on the load sensor 4 is reduced. Then, in the IC of the electronic device, an operation position and an operation load with respect to the operation panel are calculated based on an input from each of the press-type input devices 1 at a predetermined place on the back surface of the operation panel.

  The support member 2 is formed of a metal plate material such as stainless steel, and has a long bottom plate portion 11 and a pair of side plate portions 12 that rise from both end portions in the width direction of the bottom plate portion 11. A flexible substrate 3 to which the load sensor 4 is attached is attached to the back surface of the bottom plate portion 11. An opening 13 is formed in the bottom plate portion 11 along the longitudinal direction of the support member 2. The opening 13 projects the detection surface 21 of the load sensor 4 on the flexible substrate 3 from the bottom plate 11. As a method for attaching the load sensor 4, the opening 13 of the support member 2 is partially covered with a portion corresponding to the portion of the other end side of the contact plate 5 that contacts the load sensor 4, and the load is applied on the support member 2. You may stick the flexible substrate 3 to which the sensor 4 was attached.

  The bottom plate portion 11 is provided with a cantilever spring 14 extending from one end side thereof into the opening portion 13. The cantilever spring 14 is a leaf spring cut and raised from the bottom plate portion 11, and acts to attract the other end side of the contact plate 5 to the load sensor 4 via the locking portion 38 of the contact plate 5. Further, the bottom plate portion 11 is provided with a pair of long side portions 15 along the pair of side plate portions 12 by forming the opening portion 13. The pair of long side portions 15 are formed so as to receive the pair of protrusions 33 formed on the contact plate 5.

  The flexible substrate 3 is a substrate on which the load sensor 4 is provided. For example, the flexible substrate 3 is configured by forming a conductive pattern on a polyimide film as an insulating layer. The flexible substrate 3 is connected to an IC (not shown) of the electronic device, and inputs an output value from the load sensor 4 to the IC. The load sensor 4 is, for example, a force sensor using a piezoresistance effect or a piezoelectric effect, and protrudes from the opening 13 of the support member 2 with the detection surface 21 having the protrusion 22 facing upward. The other end side of the contact plate 5 attached to the support member 2 is in contact with the protrusion 22 of the load sensor 4.

  The contact plate 5 is formed of a metal plate material such as stainless steel, and has a long upper plate portion 31 and a pair of side plate portions 32 extending downward from both end portions in the width direction of the upper plate portion 31. . The distance between the outer surfaces of the pair of side plate portions 32 of the contact plate 5 is smaller than the distance between the inner surfaces of the pair of side plate portions 12 of the support member 2. For this reason, the pair of side plate portions 32 of the contact plate 5 are disposed inside the pair of side plate portions 12 of the support member 2 and face the pair of long side portions 15 of the support member 2.

  The pair of side plate portions 32 of the contact plate 5 is provided with a pair of projecting portions 33 projecting from the bottom surface (lower surface) toward the pair of long side portions 15. The contact plate 5 is swingably supported by the support member 2 by placing the pair of protrusions 33 on the pair of long sides 15. The pair of protrusions 33 constitutes a fulcrum of the contact plate 5 by being placed on the pair of long sides 15. The pair of protrusions 33 is formed by cutting out a metal plate material when the contact plate 5 is created. In addition, instead of providing the pair of protrusions 33 on the contact plate 5, it is also possible to provide a pair of protrusions 33 on the pair of long sides 15, but in this case, the metal plate material in the thickness direction Since bending is required, the present configuration in which the contact plate 5 is provided with the pair of protrusions 33 can be formed more easily.

  Moreover, in this Embodiment, although the contact plate 5 and the supporting member 2 were formed with the metal plate material, it is not limited to this, For example, you may form with a resin material. In this case, the pair of protrusions 33 can be easily formed by any configuration provided on either the contact plate 5 or the support member 2.

  On the one end side of the upper plate portion 31, a pressed portion 34 having a substantially T shape in a top view is provided. The shape of the pressed portion 34 can be changed as appropriate according to the specifications of the operation panel. For example, the pressed portion 34 can be formed in an arbitrary shape such as a round shape or a triangular shape. The pressed portion 34 faces the operation panel 6 and comes into contact with the back surface of the operation panel via a pusher 35 (see FIG. 3). A part of the pressed portion 34 is brought into contact with the operation panel via the pusher 35, thereby constituting a power point of the contact plate 5. On the other end side of the upper plate portion 31, a pressing portion 36 that faces the detection surface 21 of the load sensor 4 and presses the load sensor 4 is provided. A part of the pressing portion 36 abuts on the protrusion 22 of the load sensor 4 and constitutes an action point of the abutting plate 5.

  An opening 37 having a rectangular shape in a top view is formed in a substantially middle portion of the upper plate portion 31. The upper plate portion 31 is provided with a locking portion 38 extending from the pressing portion 36 side into the opening portion 37. The locking portion 38 is bent in a substantially L shape in a side view and locks the free end side of the cantilever spring 14 extending from the support member 2. When the locking portion 38 locks the cantilever spring 14, the pressing portion 36 is attracted to the load sensor 4 side by the spring force of the cantilever spring 14. An initial load is generated in the load sensor 4 by the pressing portion 36 being attracted by the cantilever spring 14.

  The contact plate 5 configured as described above causes the operation load from the operation panel 6 to act on the pressing portion 36 with the pair of protrusions 33 as fulcrums. In this case, the operation load from the operation panel 6 acts on the pressing portion 36 in a direction to reduce the initial load on the load sensor 4. Therefore, even if an overload is applied to the operation panel 6, a load greater than the initial load does not act on the load sensor 4, so that the load sensor 4 is prevented from being damaged.

  With reference to FIG. 3, the load transmission structure by the contact plate will be described. FIG. 3 is an explanatory diagram of a load transmission structure by the contact plate according to the present embodiment. 3A and 3B are diagrams in which the distance between the fulcrum and the force point and the ratio of the distance between the fulcrum and the action point are changed.

  As shown in FIG. 3A, the contact plate 5 is supported on the bottom plate portion 11 (the pair of long side portions 15) of the support member 2 by a pair of protrusions 33 provided on the pair of side plate portions 32. ing. The contact plate 5 is in contact with the operation panel 6 through the pusher 35 in the pressed portion 34, and is in contact with the protrusion 22 of the load sensor 4 in the press portion 36. That is, the contact plate 5 functions as a lever with the supporting position of the pair of protrusions 33 as the fulcrum P1, the pressed position where the pusher 35 is provided as the force point P2, and the pressing position of the pressing part 36 as the action point P3. . In this state, when an operation load is applied from the operation panel 6 to the force point P2 of the pressed portion 34, the contact plate 5 is swung with the support position of the pair of protrusions 33 as a fulcrum P1.

  At this time, the magnitude of the operation load acting on the action point P3 of the pressing portion 36 changes according to the distance between the fulcrum P1 and the force point P2 and the ratio of the distance between the fulcrum P1 and the action point P3. In FIG. 3A, the distance between the fulcrum P1 and the force point P2 and the distance between the fulcrum P1 and the action point P3 are set to about 1: 1. Therefore, the operation load from the operation panel 6 is transmitted to the action point P3 of the pressing portion 36 without being substantially changed. Since the operation load transmitted to the pressing portion 36 acts in the opposite direction to the initial load, the initial load on the load sensor 4 is reduced.

  In addition, by changing the distance between the fulcrum P1 and the force point P2 and the ratio of the distance between the fulcrum P1 and the action point P3, the detection sensitivity can be adjusted and the load sensor 4 with various rated loads can be supported. For example, as shown in FIG. 3B, the distance between the fulcrum P1 and the force point P2 and the distance between the fulcrum P1 and the action point P3 may be set to about 1: 2. In this case, the operation load from the operation panel 6 is almost halved and transmitted to the action point P3 of the pressing portion 36.

  Thus, by changing the position of the fulcrum P1, the operation load applied to the force point P2 can be changed and transmitted to the action point P3, and the sensor sensitivity of the load sensor 4 can be adjusted. Specifically, the sensor sensitivity can be increased by increasing the output from the load sensor 4 by reducing the distance between the fulcrum P1 and the action point P3. Further, by increasing the distance between the fulcrum P1 and the action point P3, the output from the load sensor 4 can be lowered and the sensor sensitivity can be lowered. Therefore, the sensor sensitivity of the load sensor 4 can be adjusted according to the product specifications of the electronic device and the mounting position of the electronic device.

  Further, by increasing the distance between the fulcrum P1 and the action point P3, the load acting on the load sensor 4 can be reduced, and the load sensor 4 having a smaller rated load can be used. Therefore, the design freedom of the pressing input device 1 can be improved.

  With reference to FIG. 4, the installation range of the fulcrum of the pressing type input device will be described. FIG. 4 is an explanatory diagram of the installation range of the fulcrum of the pressing input device according to the present embodiment. FIG. 4A shows the installation range of the fulcrum of the press input device according to this embodiment, and FIG. 4B shows the installation range of the fulcrum of the press input device according to the comparative example. The press input device according to the comparative example forms a fulcrum for supporting the contact plate by cutting and raising the base end side of the cantilever spring of the support member instead of providing a pair of protrusions on the contact plate. Yes. 4A and 4B, the contact plate is indicated by a broken line for convenience of explanation.

  As shown in FIG. 4A, in the present embodiment, the pair of protrusions 33 are placed on the pair of long sides 15 on both sides along the extending direction of the cantilever spring 14, The contact plate 5 is supported by the support member 2 so as to be swingable. As described above, since the pair of protrusions 33 are supported on both sides of the cantilever spring 14, the installation range of the fulcrum is not limited by the cantilever spring 14. Therefore, in the press-type input device 1 according to the present embodiment, a fulcrum can be provided along the pair of side plate portions 12 in the range indicated by L1 excluding the notch portions 16.

  On the other hand, as shown in FIG. 4B, in the comparative example, one end side of the contact plate 44 is placed on the support plate portion 43 cut and raised upward on the base end side of the cantilever spring 42. The contact plate 44 is supported by the support member 45 so as to be swingable. Thus, since the support plate portion 43 is formed by cutting and raising the base end side of the cantilever spring 42, the installation range of the fulcrum is limited to the base end side of the cantilever spring 42. Therefore, in the press-type input device 41 according to the comparative example, the fulcrum can be provided only in the range of L <b> 2 indicating the proximal end side of the cantilever spring 42.

  In the press-type input device 41 according to this comparative example, the installation range of the fulcrum can be expanded by changing (for example, shortening) the extension length of the cantilever spring 42, but the spring force of the cantilever spring 42 is increased. Since it changes, adjustment of the sensor sensitivity of the load sensor 46 becomes complicated. On the other hand, in the press input device 1 according to the present embodiment, the fulcrum installation range can be made wider than the press input device 41 according to the comparative example without affecting the cantilever spring 14. The sensor sensitivity of the sensor 4 can be easily adjusted.

  Moreover, since the fulcrum can be installed only on the base end side of the cantilever spring 42 in the pressing input device 41 according to the comparative example, the extending length of the support member 45 and the contact plate 44 becomes long depending on the installation position of the fulcrum. Larger equipment. On the other hand, the pressing type input device 1 according to the present embodiment can install the fulcrum on both sides of the cantilever spring 14, so that the support member 2 and the contact plate 5 are not affected by the installation position of the fulcrum. The extension length can be fixed short, and the apparatus can be miniaturized. As described above, in the press input device 1 according to the present embodiment, the degree of freedom of the installation position of the fulcrum is improved.

  With reference to FIG. 5, the input operation of the pressing type input device will be described. FIG. 5 is an explanatory diagram of an input operation of the press-type input device according to the present embodiment. 5A shows a non-operation state of the operation panel, and FIG. 5B shows an operation state of the operation panel.

  As shown in FIG. 5A, when the operation panel 6 is not operated, the pressing portion 36 is attracted to the load sensor 4 by the elastic force of the cantilever spring 14. The pressing part 36 contacts the protrusion 22 of the load sensor 4 at the action point P3. At this time, since the operation load is not applied to the operation panel 6, the elastic force of the cantilever spring 14 is applied to the load sensor 4 as the initial load F <b> 1 through the pressing portion 36.

  As shown in FIG. 5B, when the operation panel 6 is pressed by the operation load F2 from the non-operation state, the pressing portion 36 uses the position where the operation load is supported by the support member 2 as a fulcrum. Is transmitted to. At this time, the magnitude of the operation load F2 is varied according to the distance between the fulcrum P1 and the force point P2 and the ratio of the distance between the fulcrum P1 and the action point P3. In this embodiment, since the distance between the fulcrum P1 and the force point P2 and the distance between the fulcrum P1 and the action point P3 are set to about 1: 1, the magnitude of the operation load F2 does not substantially change, and the operation load Only the direction is converted to the reverse direction and transmitted to the pressing portion 36.

  The operation load F2 transmitted to the pressing portion 36 (the action point P3) acts in the opposite direction to the pressing direction by the pressing portion 36. As a result, the attractive force of the cantilever spring 14 is relaxed, the initial load F1 is reduced, and the load F3 acts on the load sensor 4. As described above, as the operation load on the operation panel 6 increases, the load acting on the load sensor 4 decreases, so that a load greater than the initial load F1 does not act on the load sensor 4. Therefore, the load sensor 4 is not applied with a load higher than the rated load, and the load sensor 4 can be prevented from being damaged. The load sensor 4 outputs the load received from the pressing part 36 to the IC of the electronic device as a signal corresponding to the operation load.

  The IC of the electronic device calculates the operation position and the operation load for the operation panel 6 according to the output value from the load sensor 4. For example, the IC specifies the operation position and the operation load on the operation panel 6 based on the ratio of the output values from the load sensors 4 of the plurality of push-type input devices 1 arranged at the four corners of the operation panel 6. In the present embodiment, the operation position and the operation load are calculated by the IC of the electronic device. However, the operation position and the operation load may be calculated by providing the IC on the flexible substrate 3 and pressing the input device 1. . Further, for example, one pressing type input device 1 may be provided on the operation panel. In this case, the output value of the operation position obtained from the operation position detecting means of the operation panel 6 and the load sensor 4 are used. The output value of the operation load is output to the IC of the electronic device.

  When the pressure on the operation panel 6 is released from the operation state shown in FIG. 5B, the operation load acting in the opposite direction to the pressing direction of the pressing portion 36 is removed. Then, the elastic force of the cantilever spring 14 is again applied as the initial load F <b> 1 to the load sensor 4 through the pressing portion 36.

  As described above, according to the press-type input device 1 according to the present embodiment, the initial load acting on the load sensor 4 due to the operation load from the operation panel 6 is reduced. Even if is applied, the load sensor 4 is prevented from being damaged. Further, since the contact plate 5 is supported by the support member 2 on both sides of the cantilever spring 14, the installation range of the fulcrum is not limited. In the contact plate 5, the sensor sensitivity of the load sensor 4 can be adjusted by changing the distance between the fulcrum and the force point and the distance between the fulcrum and the action point. In this case, since the degree of freedom of installation of the fulcrum is high, the sensor sensitivity of the load sensor 4 can be adjusted in a wide range.

  In the above-described embodiment, the contact plate is swingably supported by the support member by the pair of protrusions, but the present invention is not limited to this. The contact plate may be configured to be swingably supported by the support member. For example, the contact plate may be swingably supported by undulations provided on either the contact plate or the support member.

  In the above-described embodiment, the initial load is applied to the load sensor through the contact plate by a single cantilever spring, but the present invention is not limited to this. If an area where the contact plate is supported by the support member, such as a long side portion, is left on both sides along the extending direction, an initial load may be applied to the load sensor by a plurality of cantilever springs.

  In the above-described embodiment, the cantilever spring is formed by cutting and raising a part of the metal plate-like support member. However, the present invention is not limited to this. The cantilever spring may be configured to be inserted into a resin support member.

  In the above-described embodiment, the cantilever spring is a leaf spring. However, the present invention is not limited to this. The cantilever spring may have any configuration as long as it extends along the extending direction of the contact plate and causes the load sensor to generate an initial load via the contact plate.

  In the above-described embodiment, the contact plate is exemplified by the metal plate material as the contact member, but is not limited thereto. The contact member may be formed in any way as long as it extends from one end side to which an operation load is applied to the other end side that contacts the load sensor and is supported by the support member in a swingable manner.

  The embodiment disclosed this time is illustrative in all respects and is not limited to this embodiment. The scope of the present invention is shown not by the above description of the embodiments but by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.

  As described above, the present invention has an effect that the load sensor can be prevented from being damaged even when an overload is applied, and the sensor sensitivity of the load sensor can be easily adjusted.
