(Lock electrostatic sensor 300)
Here, the lock electrostatic sensor 300 will be described. FIG. 12 is a perspective view showing a wire holder included in the lock electrostatic sensor 300. FIG. 13 is a perspective view showing the lock conducting wire 350 included in the lock electrostatic sensor 300. FIG. 14 is a cross-sectional view showing the electrostatic sensor for locking 300.

The flat plate portions 321 and 322 overlap each other in the direction inclined from the Z1-Z2 direction to the Y1 side and the Y2 side. The winding portion 311 is provided between the flat plate portion 321 and the flat plate portion 322. The flat plate portions 321 and 322 project outward from the winding portion 311 like eaves at both ends of the winding portion 311. The wire holders 310A and 310B are an example of a second wire holder.

The flat plate portion 321 is formed with a notch 331 extending from one side to the other side between two parallel sides. A fixing portion 341 is provided near the center of the flat plate portion 321 of the cutout 331.

The locking electrostatic sensor 300 includes a first locking wire 351 and a second locking wire 353, as shown in FIGS. 5, 13, and 14. The first locking wire 351 has the center conductor 31 and the insulating film 32 covering the center conductor 31. Although illustration is omitted, the second lock wire 353 has the same cross-sectional structure as the first lock wire 351. The first lock wire 351 is an example of a third wire, and the second lock wire 353 is an example of a fourth wire.

One end of the first lock wire 351 is connected to the control unit 150 on the X1 side, and in the wire holder 310A, the first lock wire 351 is connected to the flat plate portion 321 and the flat plate portion 322 through the cutout 331. And is wound around the winding portion 311. The first lock wire 351 wound around the winding portion 311 is drawn out of the wire holder 310A through the notch 331 of the wire holder 310A. The first locking wire 351 pulled out of the wire holder 310A enters between the flat plate portions 321 and 322 through the notch 331 in the wire holder 310B and is wound around the winding portion 311. The other end 352 of the first lock wire 351 is an open end and is arranged inside the wire holder 310B. In both the wire holders 310A and 310B, the first locking wire 351 is crimped and fixed to the fixing portion 341 so as not to be detached from the wire holders 310A and 310B. The number of windings of the first locking wire 351 is not particularly limited, but is preferably a plurality of times, for example, two times. The winding portion 311 is an example of a third winding portion.

The wire holder 310A around which the first lock wire 351 is wound is supported by the support portion 122A, and the wire holder 310B around which the first lock wire 351 is wound is supported by the support portion 122B. In this way, the locking electrostatic sensor 300 is supported by the support portions 122A and 122B of the inner case 120.

As shown in FIGS. 5 and 13, the first lock wire 351 has a portion located between the wire holder 310A and the control unit 150 on the outer case 110 side of the wire holder 210. The second locking wire 353 is adjacent to a portion of the first locking wire 351 located on the outer case 110 side of the wire holder 210, and is connected to the control unit 150 in parallel with this portion.

(Control unit 150)
The control unit 150 applies a ground potential to the first unlocking wire 251 and the second unlocking wire 353, for example, and the capacitance of a capacitor having the second unlocking wire 253 as one electrode, The capacitance of a capacitor having the first locking wire 351 as one electrode is detected. Then, the door 10 is controlled to be locked (locked) and unlocked (unlocked) according to the detection result of the electrostatic capacitance. The control unit 150 is an example of a control unit.

For example, when the hand approaches the door handle 100 from the Z2 side toward the Z1 side and comes into contact with the surface 125 of the door handle 100 on the Z2 side, the second unlocking wire 253 serves as one electrode of the capacitor. The capacitance increases. Therefore, the door 10 can be unlocked when the capacitance reaches the threshold value.

When the hand approaches the door handle 100 from the Z1 side toward the Z2 side, the first unlocking wire 251 is interposed between the second unlocking wire 253 and the outer case 110. The increase in capacitance is suppressed. Therefore, the door 10 is not unlocked only when the hand approaches the outer case 110.

In this way, unless the user puts his/her hand inside the door handle 100, brings his/her hand close to the door handle 100, and makes contact with the inner surface 125 of the door handle 100, the door 10 is not unlocked, and the operator does not operate. It is possible to prevent the unlocking due to the unintended operation of.

Further, when the hand approaches the door handle 100 from the Z1 side toward the Z2 side and contacts the vicinity of the lock electrostatic sensor 300, the electrostatic charge of the capacitor having the first lock wire 351 as one electrode. Capacity goes up. Therefore, the door 10 can be locked when the capacitance reaches the threshold value.

When the hand approaches the vicinity of the unlocking electrostatic sensor 200 instead of the vicinity of the locking electrostatic sensor 300, the second locking wire 353 is provided between the first locking wire 351 and the outer case 110. Because of the interposition of, the increase in capacitance is suppressed. Therefore, even if the hand approaches the vicinity of the unlocking electrostatic sensor 200, the door 10 is not locked.

In this way, unless the user brings his or her hand close to the predetermined position of the door handle 100, the door 10 is not locked, and it is possible to prevent the door 10 from being locked by an unintended operation.

As described above, according to the present embodiment, locking and unlocking of the door 10 can be appropriately controlled.

Further, when the unlocking electrostatic sensor 200 is manufactured, the shape of the wire holder 210 may be suitable for the outer case 110 and the inner case 120 even when the outer case 110 and the inner case 120 have different shapes. That is, since the second unlocking wire 253 and the first unlocking wire 251 are only wound around the wire holder 210, the configurations of the second unlocking wire 253 and the first unlocking wire 251 themselves can be changed. The second unlocking wire 253 and the first unlocking wire 251 can be used in various vehicles without modification. For example, if the wire holder 210 is made of resin, the unlocking electrostatic sensor 200 can be applied to various vehicles only by changing the mold or the like used for the molding.

Similarly, when manufacturing the electrostatic sensor for locking 300, even if the outer case 110 and the inner case 120 have different shapes, the shape of the wire holders 310A and 310B may be suitable for the outer case 110 and the inner case 120. .. That is, since the first locking wire 351 is only wound around the wire holders 310A and 310B, the first locking wire 351 is used in various vehicles without changing the configuration of the first locking wire 351 itself. be able to. For example, if the wire holder 310A is made of resin, the locking electrostatic sensor 300 can be applied to various vehicles by simply changing the mold used for the molding.

As described above, according to this embodiment, the customizability can be improved.

In the present embodiment, the lock electrostatic sensor 300 includes two wire holders 310A and 310B, but the number of wire holders included in the lock electrostatic sensor 300 may be one, or three or more. Good.

Further, the wire holder included in the electrostatic sensor for locking 300 may be provided with a winding portion for the second locking wire 353, and the second locking wire 353 may be wound around this winding portion.

(Second embodiment)
Next, a second embodiment will be described. The second embodiment differs from the first embodiment in the functions of the unlocking electrostatic sensor 200, the locking electrostatic sensor 300, and the control unit 150. Hereinafter, these differences will be described.

(Detection by the electrostatic sensor 200 for unlocking)
In the second embodiment, the control unit 150 applies a voltage to each of the first unlocking wire 251 and the second unlocking wire 253 so that the first unlocking wire 251 and the second unlocking wire 251 are applied. The capacitance of the lock wire 253 is measured.

When a hand, which is an operating body, approaches the unlocking electrostatic sensor 200, the capacitance value detected by the first unlocking wire 251 and the second unlocking wire depending on the approaching direction of the hand. It is different from the capacitance value detected by 253.

A specific description will be given with reference to FIGS. When the hand approaches the unlocking electrostatic sensor 200 from the Z2 side toward the Z1 side, the distance between the hand and the second unlocking wire 253 is smaller than the distance between the hand and the first unlocking wire 251. It gets shorter. Therefore, in this case, the capacitance value detected by the second unlocking wire 253 is larger than the capacitance value detected by the first unlocking wire 251, and the second unlocking wire 253 has a larger capacitance value. The value obtained by subtracting the value of the electrostatic capacitance detected by the first unlocking wire 251 from the value of the electrostatic capacitance detected by the unlocking wire 253 is positive.

It should be noted that the judgment is not made based on whether the value is positive or negative, but based on whether each value exceeds a predetermined value, or whether it is a change in the positive direction or a change in the negative direction. Good. It may be possible to make a judgment with reference to the direction of change or comparison with a predetermined value in consideration of variations and fluctuations in the reference value of the output for each electrostatic sensor. The same applies to a lock electrostatic sensor described later.

When the hand approaches the unlocking electrostatic sensor 200 from the Z1 side toward the Z2 side, the distance between the hand and the first unlocking wire 251 is larger than the distance between the hand and the second unlocking wire 253. The distance becomes shorter. Therefore, in this case, the capacitance value detected by the second unlocking wire 253 is smaller than the capacitance value detected by the first unlocking wire 251, and the second unlocking wire 253 has a smaller capacitance value. The value obtained by subtracting the value of the electrostatic capacitance detected by the first unlocking wire 251 from the value of the electrostatic capacitance detected by the unlocking wire 253 is negative.

Further, when the hand approaches the unlocking electrostatic sensor 200 from the Y1 side or the Y2 side, the distance between the hand and the first unlocking wire 251 and the hand and the second unlocking wire 251. It is approximately equal to the distance of 253. Therefore, in this case, the value of the electrostatic capacitance detected by the first unlocking wire 251 and the value of the electrostatic capacitance detected by the second unlocking wire 253 are substantially equal to each other. The value obtained by subtracting the value of the electrostatic capacitance detected by the first unlocking wire 251 from the value of the electrostatic capacitance detected by the unlocking wire 253 is substantially zero.

As described above, when unlocking the door 10, the hand approaches the door handle 100 from the Z2 side toward the Z1 side and contacts the surface of the door handle 100 on the Z2 side. Therefore, if the value obtained by subtracting the capacitance value detected by the first unlocking wire 251 from the capacitance value detected by the second unlocking wire 253 is positive, Can be determined to be present on the Z2 side of the door handle 100, and only in this case the door is unlocked.

If the value obtained by subtracting the value of the capacitance detected by the first unlocking wire 251 from the value of the capacitance detected by the second unlocking wire 253 is 0, Can be determined to exist on the Y1 side or the Y2 side of the door handle 100, and in this case, the door is not unlocked.

If the value obtained by subtracting the value of the capacitance detected by the first unlocking wire 251 from the value of the capacitance detected by the second unlocking wire 253 is negative, Can be determined to be present on the Z1 side of the door handle 100, and in this case as well, the door is not unlocked.

By performing such control, the door is unlocked only in the case of an operation intended to unlock the door where the hand comes into contact with the surface of the door handle 100 on the Z2 side. Therefore, the unlocking of the door is not intended. It is possible to prevent the door lock from being released by the movement of the hand, and prevent false detection of the door lock release.

FIG. 15 shows the capacitance detected by the first unlock wire 251 and the second unlock wire 253 when the hand touches the door handle 100 on the Z2 side and the Z1 side. The value obtained by subtracting the capacitance detected by the first unlocking wire 251 from the capacitance detected by the second unlocking wire 253 is shown.

As shown in FIG. 15, when the hand comes in contact with the Z2 side of the door handle 100, the electrostatic capacitance detected by the first unlock wire 251 and the electrostatic capacitance detected by the second unlock wire 253. The generated electrostatic capacitance increases together, but the electrostatic capacitance detected by the second unlocking wire 253 is larger than the electrostatic capacitance detected by the first unlocking wire 251. The value obtained by subtracting the capacitance detected by the first unlock wire 251 from the capacitance detected by the unlock wire 253 becomes positive.

Further, even when the hand comes into contact with the Z1 side of the door handle 100, the capacitance detected by the first unlock wire 251 and the capacitance detected by the second unlock wire 253. , But the capacitance detected by the second unlock wire 253 is smaller than the capacitance detected by the first unlock wire 251 and the second unlock wire 253. The value obtained by subtracting the capacitance detected by the first unlocking wire 251 from the capacitance detected by is negative.

Although not shown in FIG. 15, when the hand comes into contact with the door handle 100 on the Y1 side or the Y2 side, the electrostatic capacitance detected by the first unlocking wire 251 and the second The capacitances detected by the unlock wire 253 both increase, but the capacitance detected by the first unlock wire 251 and the capacitance detected by the second unlock wire 253. Are substantially equal to each other, and the value obtained by subtracting the capacitance detected by the first unlocking wire 251 from the capacitance detected by the second unlocking wire 253 is substantially zero.

Therefore, in the control unit 150, only when the value obtained by subtracting the capacitance detected by the first unlocking wire 251 from the capacitance detected by the second unlocking wire 253 becomes positive. By controlling to unlock the door, it is possible to prevent the door from being unlocked accidentally.

Therefore, the door handle 100 according to the present embodiment unlocks the door when the hand touches the Z2 side of the door handle 100, but when the hand touches the Z1 side of the door handle 100 or the Y1 side. If it is touched on the Y2 side or the Y2 side, it is determined that the operation is not intended to unlock the door, and the door is not unlocked.

That is, the door handle 100 in the present embodiment is not detected as an operation for unlocking the door when the hand comes into contact on the Z1 side, the Y2 side, or the Y1 side of the door handle 100, and the hand is not detected. Only when the Z2 side of the door handle 100 comes into contact, it is detected that the operation for unlocking the door is performed.

(Detection by the electrostatic sensor for lock 300)
In the second embodiment, a voltage is applied from the control unit 150 to each of the first lock wire 351 and the second lock wire 353, and the first lock wire 351 and the second lock wire 353 are applied. The capacitance at is measured.

In the lock electrostatic sensor 300 in the present embodiment, the value obtained by subtracting the value of the electrostatic capacitance detected by the second lock wire 353 from the value of the electrostatic capacitance detected by the first lock wire 351 is set. Based on this, the hand operation is detected.

In the locking electrostatic sensor 300 according to the present embodiment, the first locking wire 351 is formed longer than the second locking wire 353, so that the capacitance is large. Therefore, in the present embodiment, the second lock wire 353 detects from the capacitance value detected by the first lock wire 351 when the hand is not approaching the lock electrostatic sensor 300. A value obtained by subtracting the capacitance value is used as an initial value, and a hand operation is detected based on this initial value.

In the locking electrostatic sensor 300 in the present embodiment, the region where the wire holders 310A and 310B are provided functions as a detection region, and the first locking wire 351 is formed in this detection region. The second locking wire 353 is not formed. Therefore, when a hand approaches the detection area of the lock electrostatic sensor 300, the capacitance value detected by the first lock wire 351 increases, but detected by the second lock wire 353. The value of the applied capacitance hardly changes. Therefore, the value obtained by subtracting the value of the electrostatic capacitance detected by the second locking wire 353 from the value of the electrostatic capacitance detected by the first locking wire 351 becomes larger than the initial value.

On the other hand, the area between the wire holder 310A and the control unit 150 functions as a non-detection area, and both the first lock wire 351 and the second lock wire 353 are formed in this non-detection area. ing. Therefore, when the hand approaches the non-detection region of the electrostatic lock sensor 300, the electrostatic capacitance detected by the first lock wire 351 is also the electrostatic capacitance detected by the second lock wire 353. Although the capacitance also increases, the amount of increase in capacitance is about the same. Therefore, the value obtained by subtracting the value of the capacitance detected by the second lock wire 353 from the value of the capacitance detected by the first lock wire 351 is almost the same as the initial value.

Therefore, using the initial value or a value slightly higher than the initial value as the reference value, the capacitance detected by the second locking wire 353 from the capacitance value detected by the first locking wire 351. If the value obtained by subtracting the value of exceeds the reference value, it is determined that the lock operation is performed by hand. On the other hand, even if the value of the capacitance detected by the first lock wire 351 and the value of the capacitance detected by the second lock wire 353 increase, the first lock wire 351 If the value obtained by subtracting the value of the electrostatic capacity detected by the second locking wire 353 from the value of the electrostatic capacity detected by is less than the reference value, it is determined that the locking operation by hand has not been performed. to decide.

Thereby, the operation by the hand can be detected only when the hand approaches the detection area of the electrostatic sensor for locking 300, and the operation by the hand is not detected when the hand approaches the non-detection area. Can be In this way, it is possible to prevent erroneous detection of the door lock due to the hand operation.

FIG. 16 shows that when a hand touches the door handle 100 on the Z2 side of the non-detection area of the electrostatic lock sensor 300, or when it touches the Z1 side of the non-detection area, the detection area of the electrostatic lock sensor 300 is changed. When approaching, from the capacitance detected by the first lock wire 351, the capacitance detected by the second lock wire 353, and the capacitance detected by the first lock wire 351. A value obtained by subtracting the electrostatic capacitance detected by the second lock wire 353 is shown.

As shown in FIG. 16, when the hand touches the door handle 100 on the Z1 side of the non-detection area of the electrostatic lock sensor 300, the electrostatic capacitance detected by the first lock wire 351 and , The electrostatic capacitance detected by the second lock wire 353 increases, but the electrostatic capacitance detected by the first lock wire 351 and the electrostatic capacitance detected by the second lock wire 353 increase. The capacitances are substantially equal, and the value obtained by subtracting the capacitance detected by the second lock wire 353 from the capacitance detected by the first lock wire 351 becomes substantially zero.

Further, when a hand comes into contact with the door handle 100 on the Z2 side of the non-detection region of the electrostatic lock sensor 300, the electrostatic capacitance detected by the first lock wire 351 and the second lock The capacitance detected by the use wire 353 increases together, but the capacitance detected by the first lock wire 351 and the capacitance detected by the second lock wire 353 are substantially equal, The value obtained by subtracting the electrostatic capacity detected by the second locking wire 353 from the electrostatic capacity detected by the first locking wire 351 becomes substantially zero.

On the other hand, when the hand approaches the detection area of the lock electrostatic sensor 300, the capacitance detected by the first lock wire 351 and the second lock wire Although the capacitance detected by 353 increases, the capacitance detected by the first locking wire 351 is larger than the capacitance detected by the second locking wire 353, and the first The value obtained by subtracting the capacitance detected by the second lock wire 353 from the capacitance detected by the lock wire 351 is positive.

Therefore, in the control unit 150, only when the value obtained by subtracting the electrostatic capacitance detected by the second lock wire 353 from the electrostatic capacitance detected by the first lock wire 351 becomes positive, By controlling to lock the door, it is possible to prevent the door from being accidentally locked.

Therefore, in the door handle 100 according to the present embodiment, when the hand contacts the vicinity of the detection area of the locking electrostatic sensor 300, the door is locked, and the hand closes the non-detection area of the locking electrostatic sensor 300. When touching, the door is not locked because it is judged that the operation is not intended to lock the door.

According to the present embodiment, the customizability can be improved as in the first embodiment. Further, the door can be unlocked and locked with higher accuracy according to the approaching location and approaching direction of the hand.
