Description

  The present invention relates to a keyless entry system that enables locking / unlocking of a door of a vehicle such as an automobile without a key operation, and relates to a door opening / closing device used for a vehicle door or a building door.

  In recent years, an increasing number of vehicles such as automobiles are equipped with a keyless entry system for the purpose of improving convenience and security.

  The keyless entry system is a system that enables the door to be locked / unlocked without key operation, and collates password data etc. by wireless communication between the wireless communication terminal carried by the driver and the in-vehicle wireless communication terminal. The door is locked / unlocked.

  Conventionally, an automobile door handle as a vehicle shown in FIG. 8 has been proposed for such a keyless entry system.

  The door handle 1 has a hollow handle body 4 assembled to an opening 3 of a door 2 of an automobile and serving as a grip when the door is opened and closed, and a handle operation detection is detected in the hollow portion 4a in the handle body 4. The sensor 5 is incorporated.

  The handle operation detection sensor 5 takes into account that when the driver touches the handle body 4 with his / her hand, the capacitance around the handle body 4 varies due to contact with the human body, and the variation in the capacitance occurs. The sensor electrode 6 for detecting the presence / absence of an opening / closing operation of the door and further detecting a change in capacitance, and when the change of the capacitance more than a certain level is detected by the sensor electrode 6, the driver carries the vehicle. It is the structure provided with the antenna 7 which transmits / receives a signal between radio | wireless communication terminals (for example, refer patent document 1).

  The handle body 4 is connected to the door side with an arm 8 extending from the front part so as to be able to swing and displace in the direction of the arrow (A). Further, a rear side of the handle body 4 is equipped with a key cylinder 9 that locks from the outside so that the door 2 is not opened without permission, and a bell crank body 10. The bell crank body 10 constitutes a door lock device in cooperation with a link mechanism (not shown).

  However, the door handle 1 has to secure a hollow portion 4a of a certain size or more in the handle body 4 in order to incorporate the handle operation detection sensor 5, and the shape and dimensions of the handle body 4 are limited. There was a problem that.

  Moreover, the electrostatic capacitance around the handle body 4 slightly fluctuates due to, for example, the approach or contact of an instrument other than the human body.

  Therefore, if the detection sensitivity of the capacitance type handle operation detection sensor 5 is set to be low so as not to erroneously detect such a minute change in capacitance due to disturbance, the handle at the time of opening / closing the door 2 is set. When the contact pressure of the fingers on the main body 4 is weak, it is impossible to detect whether the door 2 is opened or closed, and it is necessary to re-contact the fingers with the handle main body 4, which may cause a decrease in operability. .

  On the other hand, if the detection sensitivity of the handle operation detection sensor 5 is increased, the presence or absence of the opening / closing operation of the door 2 can be reliably detected even when the contact pressure of the finger on the handle body 4 during the opening / closing operation of the door 2 is weak. On the other hand, the handle operation detection sensor 5 determines that the door 2 has been opened / closed even when the capacitance fluctuates slightly due to disturbance, and transmits a signal. There was a risk of noise emission.

  Further, as shown in FIG. 9, the door of the automobile is provided with a door lock knob 11 for locking a door lock device (not shown) from the indoor side so that the door 2 does not open freely during traveling. Therefore, when getting off the parked vehicle, the door lock knob 11 is first unlocked, and then the inner door handle 12 is operated to detachably engage the U-shaped receiver provided on the automobile body 13. The door 2 is opened to the outside while removing (hereinafter referred to as release) the door engaging means (not shown) formed of a hook.

  Of course, even when opening the door 2 from the outside and getting into the car, the door lock device is unlocked by inserting the key into a key cylinder (not shown) and turning it, and then operating the outer door handle. The door 2 is opened outward while releasing the door engaging means. In the figure, 14 is a window glass and 15 is a driving handle.

  As mentioned above, the car opens the door from both the outside and inside, so when the door lock device locks the door, unlock it, then operate the inside door handle or outside door handle, The door is opened while releasing the door engaging means engaged with the automobile body. Accordingly, at least the timing when the unlocking of the door lock device is completed is optimal in terms of the door opening operation until the operation of releasing the door engaging means with the inner door handle or the outer door handle is completed.

  From the viewpoint of such door opening / closing operation of an automobile, the above prior art does not disclose any technology related to a handle operation detection sensor at the time of door opening / closing operation from the passenger compartment side, and tentatively opens and closes the door from the passenger compartment side. If an operation is detected, it is conceivable to provide a handle operation detection sensor in the inner door handle in the same manner as the configuration provided on the outer handle body. However, the inner door handle becomes larger and requires a lot of installation space. It is conceivable that various design constraints are imposed.

  Further, as described above, if there is a possibility that the handle opening detection sensor 5 may vary in the detection of the door opening operation depending on how the handle body 4 is gripped, the handle operation detecting sensor 5 is independent of the door engaging means releasing operation by the opening operation of the handle body. In addition, it is considered that the unlocking operation of the lock of the door lock device may be delayed, and at this time, the door opening operation by the handle body 4 must be performed again at a different timing, which may cause a decrease in operability. It is done.

Furthermore, as described with reference to FIG. 9, in order to open the door, the door lock must be unlocked, and then the door engaging means must be released by operating the door handle. The operation is complicated.

  Further, as shown in FIG. 3A, the door engaging means 25 holds the outer door handle 23 in a state where the door 21 opens the main body 20 and the L-shaped hook 31 is detached from the U-shaped receiver 29. When the door 21 is pushed toward the main body 20 and closed, the cam 35 hits the U-shaped receiver 29 and is pushed upward about the pivot 30 as indicated by the arrow. In response to this, the L-shaped rod 31 also moves upward. The door 21 closes the main body 20 as shown in FIG. 2A by engaging with the U-shaped receiver 29 while rotating.

Therefore, the operation of the outer wire 32 and the inner wire 33 is not affected.

  The door engagement release / door engagement signal detection means 27 uses a single cable-shaped piezoelectric element material 36 and detects the door opening / closing operation from outside and inside with high sensitivity. The door 21 is provided inside the door 21 so as to receive acceleration by the operation of the door engagement release / door engagement operation means 26 for releasing and engaging the door engagement means 25 by operating the inner door handle 24.

  That is, the door engagement release / door engagement signal detection means 27 is the same as the door engagement release position (position shown in FIG. 3B) including the position in the middle of releasing the door engagement means 25. The door engagement means 25 is interlocked with the door opening / closing operation from the outside or the inside at two positions including the position of the door engagement including the position in the middle of the engagement (the position shown in FIG. 2B). They are arranged so as to generate an electrical signal by being deformed by a lever 34 constituting a door engagement release / door engagement operation means 26 which is a common part.

  The door engagement release / door engagement signal detection means 27 includes a plurality of bent portions 36a in which tension is previously applied to the piezoelectric element material 36 in order to further increase the detection sensitivity of the release and engagement of the door engagement means 25. Provided, each of the bent portions 36a includes a door engagement release position (position shown in FIG. 3 (b)) including the door engagement means 25 being operated and a door engagement means 25 being engaged. It arrange | positions at the position (position shown in FIG.2 (b)) of the door engagement including, and arrange | positions so that a deformation | transformation may be received by the lever 34. The receiving portion 37 receives the piezoelectric element material 36 and reliably receives deformation due to the lever 34.

  As shown in FIG. 4, the door engagement release / door engagement signal detection means 27 includes a cable-shaped piezoelectric element material 36 having a predetermined length and a disconnection detection resistor 38 connected to one end of the piezoelectric element material 36. A door release / engagement determination means 39 connected to the other end of the piezoelectric element member 36, a cable 40 connected to the door release / engagement determination means 39, and a connector 41 connected to the tip of the cable 40. And constitutes a unit.

  The cable 40 connected to the door release / engagement determining means 39 is for supplying power and outputting a detection signal, and is connected to a power source and a communication terminal via a connector 41 provided at the tip thereof.

  The cable-shaped piezoelectric element material 36 used in the door engagement release / door engagement signal detection means 27 has the structure shown in FIG. 5 and includes a center electrode 42 disposed at the center in the axial direction and the center electrode. The piezoelectric element material 43 which is a piezoelectric ceramic coated around 45, an outer electrode 44 disposed around the piezoelectric element material 43, and a vinyl chloride resin coating layer 45 covering the outermost periphery.

  The cable-shaped piezoelectric element material 33 has excellent flexibility and generates an output signal corresponding to the deformation acceleration during deformation. For example, lead titanate or lead zirconate titanate sintered powder or lead-free piezoelectric ceramic sintered powder such as sodium niobate is used as the piezoelectric ceramic that is the piezo element material 43.

  In addition, the piezoelectric element material 36 uses a resin-based material having a heat resistance that can be used up to about 120 ° C. and has been developed by the applicant as the piezo element material 43, and a conventional typical polymer piezo element material ( It can be used in a temperature range (120 ° C. or lower) higher than 90 ° C., which is the maximum use temperature of uniaxially stretched polyvinylidene fluoride) and piezoelectric element materials (piezo element materials of chloroprene and piezoelectric ceramic powder). The piezoelectric element material 43 is composed of a flexible resin and piezoelectric ceramics, and is composed of a flexible electrode composed of a coiled metal center electrode 42 and a film-shaped outer electrode 44. Therefore, it has the same flexibility as a normal vinyl cord.

  The piezo element material 43 is composed of a resin-based material and a composite of piezoelectric ceramic powder of 10 μm or less, and vibration detection characteristics are realized by ceramics, and flexibility is realized by resin. The piezo element material 43 originally developed by the applicant uses chlorinated polyethylene as a resin-based material, realizes high heat resistance (120 ° C) and flexibility that can be easily formed, and enables a simple manufacturing process that does not require crosslinking. To do.

  The cable-like piezoelectric element material 36 obtained in this way does not have piezoelectric performance when the piezo element material 43 is molded, so that a DC high voltage of several KV / mm is applied to the piezo element material 43. Therefore, it is necessary to perform a process for imparting piezoelectric performance to the piezo element material 43 (polarization process).

  When a minute defect such as a crack is inherent in the piezo element material 43, it becomes easy to short-circuit between the two electrodes by discharging at the defective part, so that a sufficient polarization voltage cannot be applied. By establishing a unique polarization process using an auxiliary electrode that can be in close contact with the piezo element material 43, it is possible to detect and avoid defects and stabilize the polarization, thereby enabling a length of several tens of meters or more.

  In the piezoelectric element material 36, a coil-shaped metal center electrode is used for the center electrode 42, and a film-like electrode (a three-layer laminate film made of aluminum-polyethylene terephthalate-aluminum) is used for the outer electrode 44, whereby a piezo element material is obtained. As well as ensuring the adhesion between the electrode 43 and the electrode, the external lead wire can be easily connected, and a flexible cable-like mounting configuration becomes possible.

  The center electrode 42 is a copper-silver alloy coil, the outer electrode 44 is a three-layer laminate film made of aluminum-polyethylene terephthalate-aluminum, the piezo element material 43 is a polyethylene resin + piezoelectric ceramic powder, the coating layer 45 is a thermoplastic plastic, Therefore, the relative dielectric constant is 55, the charge generation amount is 10 to 13 C (coulomb) / gf, and the maximum use temperature is 120 ° C.

  The above piezoelectric element material 36 is manufactured by the following processes as an example. First, a chlorine-based polyethylene sheet and 40 to 70% by volume of piezoelectric ceramics (here, lead zirconate titanate) powder are uniformly mixed into a sheet by a roll method. After the sheet is finely cut into pellets, these pellets are continuously extruded together with the center electrode 42 to form a piezo element material 43. Then, the auxiliary electrode is brought into contact with the outer periphery of the piezo element material 43 and a high voltage is applied between the auxiliary electrode and the center electrode 42 to perform polarization treatment. Then, the outer electrode 44 is wound around the piezo element material 43. The coating layer 45 is also continuously extruded around the outer electrode 44.

  When adding the piezoelectric ceramic powder to the chlorinated polyethylene, it is preferable to immerse and dry the piezoelectric ceramic powder in a titanium / coupling agent solution in advance. By this treatment, the surface of the piezoelectric ceramic powder is covered with a hydrophilic group and a hydrophobic group contained in the titanium coupling agent.

  The hydrophilic group prevents aggregation between the piezoelectric ceramic powders, and the hydrophobic group increases wettability between the chlorinated polyethylene and the piezoelectric ceramic powder. As a result, the piezoelectric ceramic powder can be uniformly added to the chlorinated polyethylene in a large amount up to 70% by volume.

It will show fluctuations.
(1) When no load is applied to the piezoelectric element material 36 at time t0, the signal output indicates the voltage Va.
(2) When a bending load is applied to the piezoelectric element material 36 in a certain direction at time t1, the signal output increases to Vb from the moment it is applied, then immediately reverses to 0 (V), and then returns to Va again.
(3) After that, the signal output remains Va even if it is kept bent.
(4) When the piezoelectric element material 36 is returned to the original state at the time t3, the sensor output decreases to Vc from that moment, then immediately reverses to Vd, and then returns to Va again.

  Thus, since the piezoelectric element material 36 can detect the output in response to the acceleration with high sensitivity, it can detect and output a minute vibration with high accuracy. For detection of the load application timing, for example, a determination threshold value of a predetermined voltage width ΔV centered on the illustrated voltage Va is provided, and it may be determined that the load has changed when the determination threshold value is exceeded.

  In particular, in the door opening and closing device of the present embodiment, the door engagement release / door engagement signal detection means 27 is interlocked with the opening / closing operation of any door 21 from the outside and the inside. The main body side control means 28 that receives this signal controls the unlocking and locking of the door lock means 22, so that the door opening / closing operation from either the outside or the inside can be performed.

Therefore, the detection sensitivity can be set high, and the presence or absence of the door opening / closing operation can be detected sensitively by the slight displacement of the lever 34 that is displaced integrally with the door engaging means 25. Even when the gripping of the outer door handle 23 and the inner door handle 24 is weak, it is possible to reliably detect whether the door is opened or closed.

  Further, since the detection signal is not output unless the piezo element material 43 of the piezoelectric element material 36 is deformed by the displacement behavior of the lever 34 that is integrally displaced with the door engaging means 25, noise to the surrounding environment due to ineffective signal transmission is not generated. Release can also be prevented.

  Further, the door engagement release / door engagement signal detection means 27 using the piezoelectric element material 36 can be stably operated with a current consumption of 1 mA or less, so that it is compared with a conventional capacitance type handle operation detection sensor. Then, the burden on the vehicle-mounted battery can be reduced by reducing the current consumption.

Therefore, the piezoelectric element material 36 is subjected to deformation caused by the operation of the door engagement release / door engagement operation means 26 at the bent portion 36a, where the tension is applied and the detection sensitivity is increased, and detection of any door opening / closing operation from the outside or the inside is detected. Sensitivity is further increased, and it is easy to properly set the timing of releasing and engaging the door engaging means by the outer door handle or the inner door handle, and unlocking and locking the door locking means, and the door opening / closing operability. Can be further improved.

There is no time difference until operation. Therefore, the time from the door opening / closing operation until the unlocking / locking control means 48 of the main body side control means unlocks and locks the door locking means 22 can be greatly shortened, and the door is opened and closed sharply. It is possible to release and lock the locking means 22 corresponding to the above.
