Description

[Technical Field]

[0001] The present invention relates to an on-board device mounted on a vehicle. [Background technology]

[0002] One way of using automobiles is for multiple people to share one or more vehicles. Examples include car sharing and rental cars. From here on, these types of usage will be collectively referred to as "sharing."

[0003] In vehicle sharing, handling of the key for using the shared vehicle is important. For example, Patent Document 1 discloses an electronic key storage device that can be used for vehicle sharing, etc. Specifically, the storage device is provided with a pressing mechanism that presses the push button of the electronic key fitted into the fitting holder. The pressing mechanism has a solenoid that directly moves the movable iron core, a connector attached to the tip of the movable iron core and extending above the push button, and a soft elastic member attached from the tip of the connector toward the push button. In other words, the pressing mechanism is designed so that when the solenoid is activated, the elastic member approaches the push button and presses it.

[0004] In a pressing mechanism using a solenoid, an impact force that exceeds the load required to operate the push button acts on the push button, which can damage the push button or shorten its lifespan. In the technology of Patent Document 1, an elastic member is attached to the tip of the connector. It is expected that the elastic member will absorb the impact force, preventing damage to the push button and suppressing a shortened lifespan. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6710832 Summary of the Invention [Problem to be solved by the invention]

[0006] However, there are various types of electronic keys, and the number of push buttons, arrangement, actuation load, load resistance, actuation stroke, etc. vary depending on the type.

[0007] In the storage device of Patent Document 1, to accommodate misaligned push buttons, the assembly process requires adjusting the elastic member above the push button. Specifically, this requires adjusting the angle at which the connector and solenoid are attached, adjusting the length of the connector, etc. Furthermore, even when storing the same electronic key, the elastic member needs to be replaced due to wear and deterioration over time. In the storage device of Patent Document 1, the above-mentioned adjustment is also required when replacing the elastic member.

[0008] However, in the configuration of Patent Document 1, the pressing load on the push button is almost determined by the length of the connector, so if the length of the connector is fixed, the pressing load can only be adjusted by selecting the material of the elastic member attached to the tip of the connector. In other words, the design freedom for adjusting the pressing load is limited. Therefore, the range of adjustment is also limited.

[0009] An example of an object of the present invention is to provide a technique that increases the degree of freedom in designing the pressure load on a push button compared to conventional techniques. [Means for solving the problem]

[0010] One aspect of the present invention is an on-board device comprising: a storage section that stores an electronic key for a vehicle; an actuator that performs a push-button operation on the electronic key stored in the storage section; and an intermediate member that is positioned between the electronic key stored in the storage section and the actuator and transmits the force of the push-button operation to the push-button of the electronic key, wherein the intermediate member has a buffer member provided at either or both of a force point location where a movable protrusion of the actuator comes into contact and an action point location where a force is applied to the push-button of the electronic key stored in the storage section.

[0011] According to this aspect, the design elements of the pressure load on the push button are wide-ranging, and therefore the degree of freedom in designing the pressure load on the push button can be increased compared to conventional cases. [Brief explanation of the drawings]

[0013] Preferred embodiments will be described below, but the embodiments are not limited to the following. Each figure shows three orthogonal axes in a right-handed system. Furthermore, the directions will be described as follows: the positive X-axis direction is the front, the negative X-axis direction is the back, the positive Y-axis direction is the left, the negative Y-axis direction is the right, the positive Z-axis direction is the up, and the negative Z-axis direction is the down.

[0014] FIG. 1 is a diagram illustrating an example of a system configuration of a sharing system. The sharing system 3 includes a vehicle 5 to be shared, an in-vehicle device 10 that stores an electronic key 7 for the vehicle 5, a server system 1100 that connects and communicates with the in-vehicle device 10 via a network 9, and a user terminal 1500 that connects and communicates with the in-vehicle device 10 via the network 9. The electronic key 7 is a genuine key that comes with the vehicle 5. The user terminal 1500 is a terminal used by the user who is to share the vehicle. One in-vehicle device 10 is installed in the vehicle 5. When actually operating the sharing system 3, one or more sets of vehicle 5 and in-vehicle device 10 are prepared. The user terminal 1500 is, for example, a smartphone owned by each user.

[0015] The electronic key 7 has an unlock button 71, a lock button 72, a key ring 73, and a key ring attachment part 74 for attaching the key ring 73. The unlock button 71 and the lock button 72 are push buttons that unlock / lock the locking mechanism of the vehicle 5 to be shared. The electronic key 7 transmits a predetermined unlock signal when the unlock button 71 is pressed, and transmits a predetermined lock signal when the lock button 72 is pressed. The electronic key 7 may have a built-in or exposed physical key. The electronic key 7 may be an original genuine key that originally came with the vehicle 5, or it may be a key that has been duped through a procedure specified by the vehicle manufacturer. The key ring 73 may be a string or may be omitted.

[0016] The network 9 refers to a communication path that allows data communication. That is, the network 9 includes a dedicated line (dedicated cable) for direct connection, a LAN (Local Area Network) using Ethernet (registered trademark), etc., as well as a communication network such as a telephone communication network, a cable network, or the Internet, and the communication method may be either wired or wireless.

[0017] The server system 1100 performs user registration for the sharing system 3, reservation management, and provision of reservation information to the user terminal 1500 and the in-vehicle device 10. Specifically, the server system 1100 stores a management program 501 and, by executing this program, implements (1) a user registration function, (2) a reservation setting function for each vehicle 5, (3) a generation function of reservation information 700 (including, for example, a unique reservation ID, a reserved vehicle ID, a reservation period, a password, etc.), (4) a function of providing a copy of the reservation information 700 (reservation information 700t) to the user terminal 1500, and (5) a function of providing a copy of the reservation information 700 (reservation information 700c) to the in-vehicle device 10.

[0018] The user terminal 1500 is a computer system connectable to the network 9 used by users who wish to share the vehicle 5, and is realized by, for example, a smartphone, a tablet computer, a notebook computer, a wearable computer, or the like.

[0019] The user terminal 1500 can store and execute application programs. The application program stored therein is a terminal program 502. The terminal program 502 realizes (1) a function for accessing the server system 1100, (2) a function for issuing a predetermined unlock request to the in-vehicle device 10 in response to an unlock operation on the user terminal 1500 by the user, and providing the reservation information 700t to cause the in-vehicle device 10 to unlock, and (3) a function for communicating with the in-vehicle device 10 in response to a lock operation on the user terminal 1500 by the user, issuing a predetermined lock request, and providing the reservation information 700t to cause the in-vehicle device 10 to lock.

[0020] FIG. 2 is a top view showing an example of the appearance of the vehicle-mounted device 10. As shown in FIG. FIG. 3 is a diagram showing an example of the internal structure of the vehicle-mounted device 10 as viewed from the positive side of the Z axis. FIG. 4 is a diagram showing an example of the internal structure of the vehicle-mounted device 10 as viewed from the positive side in the Y-axis direction.

[0021] The vehicle-mounted device 10 is a key control device that performs an unlocking operation / locking operation on the stored electronic key 7 in response to an unlocking request / locking request from the user terminal 1500. The vehicle-mounted device 10 is installed inside the vehicle 5 that is the sharing target, for example, in the dashboard.

[0022] The vehicle-mounted device 10 has a main case portion 11 that houses a mechanism for operating the electronic key 7, a cable 13 that is connected to the battery of the vehicle 5, and a storage portion 20 that stores the electronic key 7 of the vehicle 5 in a removable manner.

[0023] The storage section 20 has a lid section 23 pivotally supported on the main case section 11 by a swing shaft 22, and a storage recess forming member 24 stretched on the inside of the lid section 23. When the opening / closing operation section 15 connecting the main case section 11 and the storage section 20 is pressed and the engagement between the opening / closing operation section 15 and the storage section 20 is released, the lid section 23 opens.

[0024] The lid 23 has an opening 25 on its side in the positive direction of the Y axis that remains open even when the lid 23 is closed. The electronic key 7 is stored so that the key ring 73 is exposed to the outside through the opening 25. By exposing the key ring 73, it is possible to confirm at a glance from the outside that the electronic key 7 is stored. By exposing the key ring 73, the user can use the key ring 73 as a knob when removing the electronic key 7 from the storage section 20.

[0025] The storage recess-forming member 24 is a member that forms a recess into which the electronic key 7 is fitted. The recess shape formed by the storage recess-forming member 24 matches the outer shape of the electronic key 7. The electronic key 7 is fitted into the storage recess-forming member 2 with the push button facing in the positive direction of the X axis and the key ring 73 facing in the positive direction of the Y axis. The storage recess-forming member 24 is molded from a cushioning material such as hard sponge, and is attached to the inside of the lid portion 23 by recess-and-protrusion fitting or double-sided tape.

[0026] There is a partition wall 17 between the storage section 20 and the main case section 11, and the central section of the partition wall 17 (the section facing the stored electronic key 7) has a large opening, allowing the internal space of the storage section 20 to communicate with the internal space of the main case section 11.

[0027] The main case 11 has an internal space formed by screwing the back cover 12, and houses the control board 30, the first actuator 41, the second actuator 42, and the intermediate member 50. If the vehicle-mounted device 10 is configured to have an internal battery, the internal battery may be housed inside the main case 11.

[0028] The control board 30 includes electronic components such as a CPU (Central Processing Unit) 31, an IC memory 32, a first wireless communication module 33, a second wireless communication module 34, a power control circuit 35, an interface IC 36, and various other circuits.

[0029] The first wireless communication module 33 connects to a network 9 (specifically, a wireless communication network such as a mobile phone network or a wireless LAN) and communicates with a server system 1100 that manages reservations for the vehicle 5 to be shared. The second wireless communication module 34 realizes short-distance wireless communication and establishes a communication connection with the user terminal 1500 that comes within a communication range centered on the vehicle 5 .

[0030] The power control circuit 35 controls the supply of power to the first actuator 41 and the second actuator 42 .

[0031] The interface IC 36 realizes input and output of signals from the first wireless communication module 33 and the second wireless communication module 34.

[0032] The control board 30 controls the operation of the vehicle-mounted device 10 in an integrated manner by executing a program stored in the IC memory 32 with the CPU 31 .

[0033] The first actuator 41 and the second actuator 42 are actuating units that are operated by drive current control from the control board 30 and perform a push-button operation on the electronic key 7 housed in the housing 20. Specifically, the first actuator 41 and the second actuator 42 are realized by push-type linear solenoids that push out a movable protrusion 43 (a push rod made of a non-magnetic material connected to a movable iron core) by electromagnetic force when a drive current is applied, and return the movable protrusion 43 to its original position before being pushed out by the force of a return spring 44 when the drive current is stopped.

[0034] No attachment is attached to the tip of the movable protrusion 43. The first actuator 41 is fixed to the main case 11 with the tip of the movable protrusion 43 facing the unlock button 71 of the electronic key 7 stored in the storage section 20. The second actuator 42 is fixed to the main case 11 with the tip of the movable protrusion 43 facing the lock button 72 of the electronic key 7 stored in the storage section 20.

[0035] The intermediate member 50 is a plate-like member that is arranged between the electronic key 7 accommodated in the accommodating section 20 and the first and second actuators 41 and 42, and transmits the pushing force of the movable protrusions 43 of these actuators to the push buttons (unlock button 71, lock button 72) of the electronic key 7 as a push button operation force.

[0036] The vehicle-mounted device 10 is provided with a plurality of types of intermediate members 50 that can be attached thereto. FIG. 5 is a view showing an example of the first intermediate member 50 (50A) as viewed from the negative side of the X axis (the housing section 20 side). FIG. 6 is a cross-sectional view of an example of the first intermediate member 50 (50A) taken along a plane parallel to the XY plane. FIG. 7 is a view showing an example of the second intermediate member 50 (50B) as viewed from the negative side of the X axis. FIG. 8 is a view showing an example of the third intermediate member 50 (50C) as viewed from the negative side of the X axis. FIG. 9 is a view showing an example of the fourth intermediate member 50 (50D) as viewed from the negative side of the X axis.

[0037] The intermediate member 50 is an elastic plate-like member such as a metal plate or a synthetic resin plate, and has a peripheral portion 51, a cantilever spring portion 52, and a gap portion 53. The gap portion 53 is provided in the plate-like member by cutting or stamping, so that the peripheral portion 51 and the cantilever spring portion 52 are formed into a single plate.

[0038] The peripheral portion 51 is a portion that is fitted into and fixed to the grooves of the mounting portions 18 (18a, 18b) of the main case portion 11. The first mounting portion 18a is provided on the inner surface of the main case portion 11, on both the Y-axis positive side and the Y-axis negative side, so as to have a groove that extends along the Z-axis direction. The second mounting portion 18b is provided on the inner surface of the Z-axis positive side of the main case portion 11, so as to have a groove that extends along the Y-axis direction.

[0039] The peripheral portion 51 and the mounting portion 18 are fitted together with enough strength to prevent them from coming loose or shifting due to vibrations of the vehicle 5, but can be pulled out by hand. The outer shape of the intermediate member 50 and the thickness of the peripheral portion 51 are the same for all types of intermediate member 50, and any type of intermediate member 50 can be attached to the mounting portion 18 (18a, 18b).

[0040] The intermediate member 50 is attached to the main case portion 11 by the peripheral edge portion 51 so as to be insertable and detachable. The intermediate member 50 can be easily attached to and detached from the main case portion 11.

[0041] The cantilever spring portion 52 functions as a "cantilevered leaf spring" by receiving a collision with the movable protrusion portion 43 in response to the operation of the first actuator 41 and the second actuator 42. Specifically, the cantilever spring portion 52 includes two portions: a first cantilever spring portion 52a that is pushed by the first actuator 41, and a second cantilever spring portion 52b that is pushed by the second actuator 42.

[0042] The cantilever spring portion 52 (52a, 52b) has a force point P1 on one of its two surfaces (the side of the first actuator 41 and the second actuator 42; the positive side of the X axis) where the movable protrusion 43 of the actuator comes into contact. The other of its two surfaces (the side of the storage unit 20; the negative side of the X axis) has an action point P2 that applies force to the push buttons (unlock button 71, lock button 72) of the electronic key 7 stored in the storage unit 20. A buffer member 54 is provided at the action point P2 so as to protrude toward the push buttons.

[0043] When the first actuator 41 or the second actuator 42 is activated, the movable protrusion 43 collides with the intermediate member 50, generating an impact force that is transmitted by the intermediate member 50 to the push buttons (unlock button 71, lock button 72) of the electronic key 7. The buffer member 54 reduces this transmitted force. The buffer member 54 can be made of, for example, silicone, butyl rubber, or a spring. The illustrated example shows a member made of silicone molded into a nipple shape.

[0044] The material of the intermediate member 50 and the width and thickness of the fulcrum portion 55 of the cantilever spring portion 52 are selected and set to satisfy the following: (1) the intermediate member 50 bends due to the load received from the movable protrusion portion 43 when the first actuator 41 and the second actuator 42 are activated, and (2) the tip of the buffer member 54 comes into contact with the push button (unlock button 71, lock button 72) of the electronic key 7 stored in the storage portion 20, and the amount of bending provides a stroke sufficient to operate the push button.

[0045] In other words, the cantilever spring portion 52 (a) is in a state where it does not press down the push button of the stored electronic key 7 when the first actuator 41 and the second actuator 42 are not activated, and (b) when the first actuator 41 or the second actuator 42 is activated, it bends sufficiently to press down the push button of the stored electronic key 7.

[0046] Even if the first actuator 41 or the second actuator 42 is activated and an impact force acts on the intermediate member 50, the deflection of the cantilever spring portion 52 and the buffer member 54 moderately reduce the transmission of the impact force to the push buttons (unlock button 71, lock button 72), protecting the push buttons from the impact force.

[0047] By employing the intermediate member 50 and the buffer member 54 and setting their specifications appropriately, the vehicle-mounted device 10 can accommodate various types of electronic keys 7.

[0048] Specifically, even if the load with which the first actuator 41 and the second actuator 42 press the intermediate member 50 is the same, the force ultimately transmitted to the push buttons (unlock button 71, lock button 72) of the electronic key 7 changes depending on the distance L1 from the fulcrum point 55 of the cantilever spring portion 52 to the force point point P1 and the distance L2 from the fulcrum point 55 to the action point point P2.

[0049] Therefore, the vehicle-mounted device 10 of this embodiment has a wide range of design freedom depending on the operating load, load resistance, and operating stroke of the push buttons (unlock button 71, lock button 72) of the electronic key 7. For example, if it is desired to make the load transmitted to the push buttons smaller than the load with which the first actuator 41 and the second actuator 42 press the intermediate member 50, this can be achieved by making the "distance L1 from the fulcrum location 55 to the force point location P1" smaller than the "distance L2 from the fulcrum location 55 to the application point location P2," as in the first intermediate member 50 (50A) shown in FIGS.

[0050] For example, if it is desired to make the load with which the first actuator 41 and the second actuator 42 press the intermediate member 50 approximately the same as the load transmitted to the push button, this can be achieved by making the "distance L1 from the fulcrum portion 55 to the force point portion P1" and the "distance L2 from the fulcrum portion 55 to the application point portion P2" the same or approximately the same, as shown in FIG. 7.

[0051] For example, compared to the electronic key 7A of FIG. 5, the electronic key 7 (7C) shown in FIG. 8 has the same relative positions of the push buttons (unlock button 71, lock button 72), but the push button has a larger actuation load or a larger actuation stroke. The third intermediate member 50 (50C) corresponding to this electronic key 7 (7C) basically has a similar design to the first intermediate member 50 (50A) of FIG. 5, but has a localized thin portion 57 at the fulcrum portion 55. Alternatively, the fulcrum portion 55 has a localized narrow portion 58. As a result, the cantilever spring portion 52 of the third intermediate member 50 (50C) is more flexible than the first intermediate member 50 (50A) of FIG. 5, allowing for a larger load to be transmitted to the push button or a larger actuation stroke.

[0052] As another specification, as in a fourth intermediate member 50 (50D) shown in FIG. 9, the overall length of the cantilever spring portion 52 may be set long and a narrow portion 58 may be further provided.

[0053] The types of intermediate members 50 provided in the vehicle-mounted device 10 are not limited to these four examples, and more types may be provided. For example, it is possible to provide intermediate members 50 of different types in which the peripheral portion 51, the cantilever spring portion 52, and the force point P1 are in the same positions, but the action point P2 is in a different position. By appropriately setting the action point P2, the intermediate members 50 can be made to correspond to different positions of the push buttons (unlock button 71, lock button 72) on the electronic key 7.

[0054] The vehicle-mounted device 10 is provided with a set of an intermediate member 50 and a storage-recess-forming member 24 that corresponds to the type of electronic key 7. As described above, the intermediate member 50 can be easily inserted into and removed from the mounting portion 18, allowing the user to easily and reliably rearrange the intermediate member 50. The storage-recess-forming member 24 can also be easily rearranged.

[0055] The vehicle-mounted device 10 includes an element that reduces the impact force in the process of transmitting the impact force of the movable protrusion 43. The element is provided independently of the first actuator 41 and the second actuator 42. This not only provides the above-mentioned excellent assembly ease and high design freedom, but also provides the secondary effect of making the vehicle-mounted device 10 smaller.

[0056] FIG. 10 is a diagram for explaining the effect of miniaturizing the vehicle-mounted device 10. In FIG. 10(2) of the vehicle-mounted device 10E, the first actuator 41E and the second actuator 42E have screw-type buffer materials 45 at the tip of the movable protrusion 43. When this type of linear solenoid is used, the structural elements required to screw the buffer materials 45 (for example, threads, double nuts to prevent loosening of the buffer materials 45, etc.) increase the overall length of the actuators, which in turn affects the overall size of the vehicle-mounted device 10E.

[0057] However, in the in-vehicle device 10 of this embodiment shown in FIG. 10(1), the cantilever spring portion 52 and the buffer member 54 of the intermediate member 50 are substituted for the buffer member 45 of FIG. 10(2). The first actuator 41 and the second actuator 42 do not include the buffer member 45 and the structural elements required to fasten it with screws. In other words, it is possible to use linear solenoids that are smaller than the first actuator 41E and the second actuator 42E. Therefore, the overall size of the in-vehicle device 10 can be made smaller than that of the in-vehicle device 10E.

[0058] <Other embodiments> Although an example of an embodiment has been described above, the aspects of the present disclosure are not limited to the above-described embodiment, and constituent elements can be added, omitted, or modified as appropriate.

[0059] (Part 1) For example, a configuration may be added in which the buffer member 54 is detachably attached to the cantilever spring portion 52. Specifically, as in the intermediate member 50 (50G) shown in FIG. 11 , a plurality of potential attachment positions 56 to which the buffer member 54 can be attached may be provided on the surface of the cantilever spring portion 52 on the negative X-axis side (the surface on the housing portion 20 side), so that the buffer member 54 can be selectively attached and detached to any of the potential attachment positions 56. The attachment mechanism may be appropriately configured. As shown in FIG. 11 , a convex portion may be provided as the potential attachment position 56, and this may be configured to fit into a concave portion on the buffer member 54 side, allowing the buffer member 54 to be attached and detached by inserting and removing it. Alternatively, an insertion hole may be provided as the potential attachment position 56, and the end of the buffer member 54 may be inserted and removed through the insertion hole, allowing the buffer member 54 to be attached and detached.

[0060] (Part 2) 12, a second buffer member 54B may be added to the force point location P1 on the positive side of the cantilever spring portion 52 along the X-axis. Instead of providing the second buffer member 54B, the buffer member 54 may be omitted, and a buffer member may be provided only at the force point location P1. In this case, a protrusion (for example, a protrusion having the same external shape as the buffer member 54 and integrally formed with the cantilever spring portion 52) may be provided on the cantilever spring portion 52 in place of the omitted buffer member 54. Alternatively, a buffer member 54H may be attached to the tip of a base portion 59 that protrudes from the force point location P2 in the negative direction of the X-axis (toward the accommodation portion 20).

[0061] (Part 3) In the above embodiment, the lid 23 of the storage unit 20 is opened and closed to store and remove the electronic key 7, but the lid 23 may be omitted. Specifically, the vehicle-mounted device 10J in FIG. 13 does not have the lid 23, and instead has an insertion opening 19 at the end of the storage unit 20J in the positive direction of the Y axis, through which the electronic key 7 can be inserted. The storage-recess-forming member 24J of the vehicle-mounted device 10J has a tubular structure with an insertion opening through which the electronic key 7 can be inserted from the positive direction of the Y axis. The electronic key 7 is inserted into and removed from the storage-recess-forming member 24J through the insertion opening 19 and the insertion opening of the storage-recess-forming member 24J.

[0062] [Summary] The disclosure of the present specification according to the above-described embodiments can be summarized as follows.

[0063] The disclosed aspect is an on-board device comprising: a storage section that stores an electronic key for a vehicle; an actuator that performs a push-button operation on the electronic key stored in the storage section; and an intermediate member that is positioned between the electronic key stored in the storage section and the actuator and transmits the force of the push-button operation to the push-button of the electronic key, wherein the intermediate member has a buffer member provided at either or both of a force point location where a movable protrusion of the actuator comes into contact and an action point location where a force is applied to the push-button of the electronic key stored in the storage section.

[0064] According to this aspect, the design elements of the pressure load on the push button are wide-ranging, such as the material and dimensions of the intermediate member, the relative positional relationship between the force point and the application point, the dimensions and material of the buffer member, etc. Therefore, the design freedom of the pressure load on the push button can be increased more than ever before.

[0065] The intermediate member may have a cantilever spring portion, the force point portion being on one of both surfaces of the cantilever spring portion, and the action point portion being on the other of both surfaces of the cantilever spring portion.
