For example, a cover that covers a part of the battery hole 51 may be provided, and the battery 23 may be held on the electronic substrate unit 50 so that the battery 23 is inserted into a space formed by the battery hole 51 and the cover.

  As shown in FIGS. 2, 3, and 4, in the thickness direction of the electronic key body 25, an operation signal is transmitted to the electronic circuit when the user presses the other end surface of the electronic substrate unit 50. A plurality of buttons 53 (three in this example) are provided. The electronic circuit determines the operation content depending on which button 53 the user has pressed.

  The button 53 is exposed outside the case from a button hole 31 provided in the first case 30. As a result, the user can press the button 53. Therefore, the case inner end surface of the first case 30 and the other end surface of the electronic substrate unit 50 face each other.

  In addition, the first indentation portion 54 that allows the first case 30 and the second case 40 to be fitted to each other and the first case 30 and the mechanical key 24 can be fitted to the electronic board portion 50. A second recess 55 is provided.

  The second recessed portion 55 is provided at one end of the electronic board portion 50 in the longitudinal direction of the electronic key body 25. The second recessed portion 55 is a groove in which a part of one end portion of the electronic substrate portion 50 is recessed in the case along the direction in which the mechanical key 24 is inserted into the electronic key body 25.

  The first dents 54 are provided at both ends of the electronic substrate unit 50 in the width direction of the electronic key body 25. Further, the first recessed portion 54 is a groove in which a part of the end surface of the electronic substrate portion 50 is recessed so as to be away from the surface of the case in the width direction of the electronic key body 25.

  As shown in FIG. 4, the first recessed portion 54 continuously approaches the second recessed portion 55 in the thickness direction of the electronic key body 25 from the one end face 50 a side toward the first case 30 side. The groove is inclined like this.

  The configurations of the second case 40 and the mechanical key 24 will be described with reference to FIGS. 6 and 7 in addition to FIGS. 2, 3, and 4. FIG. 6 is a schematic diagram showing a state where the mechanical key 24 is inserted into the second case 40. FIG. 7 is a schematic view showing a state in which the mechanical key 24 is inserted into the second case 40.

  As shown in FIGS. 6 and 7, the second case 40 has a substantially L-shaped plate portion 40 a whose longitudinal section of the electronic key body 25 is substantially L-shaped and a width direction of the electronic key body 25. It comprises a pair of substantially rectangular plate portions 40b provided at both ends of the plate portion. The second case 40 includes a pair of first protrusions 41 that can be fitted into the first recesses 54, a key hole 42 through which the mechanical key 24 can be inserted and removed, and a pair of guides that guide the mechanical key 24 into the case. Guide rails 43a and 43b are provided.

  The key hole 42 is provided at one end of the second case 40 in the longitudinal direction of the electronic key body 25. Further, the key hole 42 is provided in the second case 40 so as to come to a position overlapping the second recessed portion 55 when the second case 40 is fitted to the first case 30.

  The first protrusions 41 are provided so as to protrude into the case from both end portions of the case inner end surface of the second case 40 in the width direction of the electronic key body 25. Further, the first protrusion 41 is provided in accordance with the shape of the first recess 54. That is, the first recess 54 and the first protrusion 41 are inclined with respect to the longitudinal direction of the electronic key body 25. When the fitting state between the first case 30 and the second case 40 is released, the tilt direction is guided by the first protrusion 41 to the longitudinal direction of the electronic key body 25. The distance between the first recess 54 and the key hole 42 is set to be small.

  Therefore, when fitting the first case 30 and the second case 40, the second case 40 can be fitted by sliding obliquely with respect to the first case 30. Here, the first protrusion 41 and the first recess 54 form a first fitting mechanism, and the first case 30 and the second case 40 can be fitted together.

  The pair of guide rails 43 a and 43 b are provided so that the mechanical key 24 can be guided along the longitudinal direction of the electronic key body 25. That is, the pair of guide rails 43 a and 43 b are arranged at a distance from each other in the width direction of the electronic key body 25.

  In the width direction of the electronic key body 25, the distance between the guide rail 43 a and the guide rail 43 b is determined by the width of the mechanical key 24. Further, at least one of the guide rail 43a and the guide rail 43b is provided with a third protrusion 44 that can be fitted to the third recess 24b of the mechanical key 24. The third recess 24b will be described later.

  The third protrusion 44 is provided so as to protrude from the one guide rail 43 toward the opposing guide rail 43. In this example, the third protrusion 44 is provided on the guide rail 43a and is provided so as to protrude from the guide rail 43a to the guide rail 43b.

  As shown in FIG. 6, the mechanical key 24 includes a key head 241 including a second protrusion 24 a that can be fitted to the second recess 55, and an end of the key head 241. A key body portion 242 including a third recessed portion 24b fitted to the portion 44.

  When the mechanical key 24 is inserted into the electronic key main body 25, the key head 241 has a shape in which the second protrusion 24 a and the second recess 55 are fitted and the key hole 42 is closed. When the mechanical key 24 is inserted into the electronic key body 25, a part of the surface of the key head 241 close to the first case 30 in the width direction of the electronic key body 25 is a key close to the first case 30. It hits at least a part of the surface of the working hole 42. In this example, when the mechanical key 24 is inserted into the electronic key body 25, the key head 241 has a shape that eliminates a step from the side surface of the case.

  The second protrusion 24a protrudes in a direction in which the mechanical key 24 is guided into the case. Here, the second protrusion 24a and the second recess 55 form a second fitting mechanism, and the first case 30 and the mechanical key 24 can be fitted.

  The key body 242 is a portion that is guided along the guide rails 43 a and 43 b when the mechanical key 24 is inserted into the electronic key body 25. The key body 242 is provided with a third recess 24b that fits with the third protrusion 44 in a state in which the key body 242 is completely inserted into the second case 40 along the guide rails 43a and 43b. . The shape of the third protrusion 44 that fits into the third recess 24b is determined in accordance with the shape of the third recess 24b.

  The mechanical key 24 is held by the second case 40 when the third protrusion 44 and the third recess 24b are fitted. Here, a third fitting mechanism portion is formed by the third protrusion 44 and the third recess 24b, and the second case 40 and the mechanical key 24 can be fitted.

  Next, a method for configuring the electronic key device 2 by fitting the first case 30, the second case 40, and the mechanical key 24 will be described in detail. FIG. 8 is a cross-sectional view showing the electronic key device showing the direction in which the first case 30 and the second case 40 are fitted. FIG. 9 is a schematic diagram showing a state in which the mechanical key 24 is inserted after the first case 30 and the second case 40 are fitted.

  As a first step, as shown in FIG. 8, along the direction of arrow D, the first recessed portion 54 of the electronic substrate portion 50 held by the first case 30 and the first protruding portion of the second case 40. 41 is fitted. That is, the first case 30 and the second case 40 are fitted by the first fitting mechanism. The direction of the arrow D is determined by the inclination provided in the first recess 54 and the first protrusion 41. Thereby, the first case 30 and the second case 40 are fitted, and the electronic key body 25 is formed.

  Next, as a second step, the mechanical key 24 is inserted into the electronic key body 25 from the key hole 42. At this time, the key body 242 of the mechanical key 24 is guided into the case along the guide rails 43a and 43b.

  Finally, as a third step, the mechanical key 24 is completely inserted into the electronic key body 25, whereby the second protrusion 24 a of the key head 241 of the mechanical key 24 and the second recess 55 of the electronic substrate unit 50. And the third recess 24b of the key main body 242 of the mechanical key 24 and the third protrusion 44 of the second case 40 are fitted together. That is, the first case 30 and the mechanical key 24 are fitted by the second fitting mechanism, and the second case 40 and the mechanical key 24 are fitted by the third fitting mechanism. .

  As a result, the first case 30 and the mechanical key 24 are fixed, and the second case 40 and the mechanical key 24 are fixed. At this time, in the normal state in which the mechanical key 24 is inserted due to the fitting between the second protrusion 24a and the second depression 55 and the fitting between the third depression 24b and the third protrusion 44, the first The fitting state between the case 30 and the second case 40 does not come off. Therefore, in the state where the mechanical key 24 is inserted, the first case 30, the second case 40, and the mechanical key 24 are fixed together.

  On the other hand, when disassembling the electronic key device 2 held by fitting the first case 30, the second case 40, and the mechanical key 24, the mechanical key 24 is simply pulled out of the electronic key body 25. It's okay.

  In the electronic key device according to the first embodiment, the mechanical key is inserted into the case of the electronic key main body in which the first case and the second case are fitted by the first fitting mechanism portion, so that the second The fitting mechanism portion and the third fitting mechanism portion are fitted, and the first case, the second case, and the mechanical key are integrated.

  With such a configuration, the fitting state between the first case and the second case can be maintained in a normal state where the mechanical key is inserted into the electronic key body. That is, in the normal state where the mechanical key is inserted into the electronic key body, the first case and the second case cannot be brought into a non-fitted state.

  Further, the first case and the second case can be separated by removing the mechanical key from the electronic key body. As a result, it is possible to easily replace the battery provided on the electronic substrate held by the first case without using a tool.

  In addition, since it is not necessary to fix the first case and the second case with screws, the number of parts can be reduced and the cost can be reduced. Furthermore, since there is no need to remove the screw, the time for separating the first case and the second case can be shortened.

  In addition, the fitting direction of the first case and the second case indicated by the arrow D, that is, the fitting direction of the first fitting mechanism portion is from the second case side in the thickness direction of the electronic key body. As it goes to the first case side, it is inclined so as to continuously approach the key hole.

  Here, when the fitting direction of the first case and the second case is provided along the thickness direction of the electronic key body, that is, the first case is perpendicular to the insertion / extraction direction of the mechanical key. When the first case and the second case are fitted, the first fitting mechanism part may easily come off when a force is applied in the direction of arrow D.

  This is because when a force in the direction of arrow D is applied to the electronic key device, the second protrusion is pushed toward the first case in the second fitting mechanism that is the fitting between the first case and the mechanical key. This is because there is a risk that the force will be removed from the second recess. As a result, the electronic key device may be unintentionally disassembled.

  Therefore, the fitting direction of the first fitting mechanism portion is inclined so as to continuously approach the key hole from the second case side toward the first case side in the thickness direction of the electronic key body. By doing so, even if a force in the direction of arrow D is applied, it is possible to generate a force by which the second protrusion is pushed toward the second recess. Thereby, since a force is applied in the direction in which the second fitting mechanism portion is more engaged, it is possible to prevent the second protruding portion from coming out of the second recessed portion.

  In the first embodiment, the first case 30 is provided with the first recess 54 and the second case 40 is provided with the first protrusion 41. The first case 30 is provided with the first protrusion. And the first case may be provided with a first recess.

  Similarly, the mechanical key 24 may be provided with a second dent, and the first case 30 may be provided with a second protrusion. Alternatively, the mechanical key 24 may be provided with a third protrusion, and the second case 40 may be provided with a third recess.

Embodiment 2. FIG.
In the first embodiment, the fitting direction of the first fitting mechanism portion is changed from the second case 40 side toward the first case 30 side in the thickness direction of the electronic key main body 25, and the key The example which made it incline so that it may approach the hole 42 continuously was demonstrated. On the other hand, in the second embodiment, an example in which the fitting direction of the first fitting mechanism portion is the same direction as the insertion / extraction direction of the mechanical key 24 will be described.

  FIG. 10 is a schematic diagram showing the electronic key device 2 according to Embodiment 2 of the present invention. FIG. 11 is a schematic view showing a state in which the mechanical key 24 is removed from the electronic key device 2 in the state shown in FIG.

Further, the second case 40 has a substantially C-shaped plate portion 40c and a substantially rectangular plate portion 40d provided at one end of the substantially C-shaped plate portion 40c in the longitudinal direction of the electronic key body 25. It consists of and.

  Furthermore, in the second embodiment, the first fitting mechanism portion can hook the hook portion 32 provided at the end portion of the first case 30 and the hook portion 32 in the longitudinal direction of the electronic key body 25. It has the hook part 45 of the 2nd case 40 which can be. The hook hanging portion 45 is shown in the enlarged view of the second case 40 shown in the dotted circle in FIG.

  The hook portion 32 is provided so as to protrude from the end portion of the first case 30 toward the inside of the case in the longitudinal direction of the electronic key body 25. Therefore, the fitting direction of the first case 30 and the second case is the same direction as the insertion / extraction direction of the mechanical key 24. In this example, the hook portion 32 is provided in the entire first case 30 in the width direction of the electronic key body 25.

  The hook hanging portion 45 only needs to be able to hook the hook portion 32. Therefore, it may be directly hooked on the plate of the second case 40, or a groove for hooking on the second case 40 may be provided in accordance with the hook portion 32.

  That is, the hook 32 is guided by the hook hook 45 in a direction in which the first case 30 is released from the fitting state with the second case 40 by the first fitting mechanism. Accordingly, the distance between the hook portion 32 and the key hole 42 in the longitudinal direction of the electronic key body 25 is set to be large.

  The key hole 42 through which the mechanical key 24 can be inserted and removed is provided in the plate portion 40 d at one end portion of the second case 40 in the longitudinal direction of the electronic key body 25, and one end of the first case 30. It is also provided in the department.

  At this time, as in the first embodiment, if the key head 241 is buried in the key hole 42, the mechanical key 24 becomes difficult to take out. Therefore, in the second embodiment, the key head 241 of the mechanical key 24 is substantially T-shaped as shown in FIG. 12, and a part protrudes from the key hole 42. Therefore, the second fitting mechanism portion allows the first case 30 and the mechanical key 24 to be fitted by the portion of the key head 241 that is inserted into the key hole 42 and the key hole 42. ing.

  Here, when the mechanical key 24 is inserted into the electronic key body 25, the surface of the key head 241 that hits at least a part of the surface of the key hole 42 near the first case 30 in the width direction of the electronic key body 25 is The surface of the key head portion 241 is the portion inserted into the key hole 42 close to the first case 30. Other configurations are the same as those of the first embodiment.

  Next, a method for configuring the electronic key device 2 by fitting the first case 30, the second case 40, and the mechanical key 24 will be described in detail. As a first step, as shown in FIG. 10, the hook part 32 is hooked on the hook hanging part 45 of the second case 40. Thereafter, the first case 30 and the second case 40 are fitted. That is, the first case 30 and the second case 40 are fitted by the first fitting mechanism.

  At this time, the first case 30 and the second case 40 are a part of the second case 40 where the key hole 42 is provided, and a part of the first case 30 where the key hole 42 is provided. It fits so that it may be arrange | positioned rather than 30 inside a case.

  Next, as a second step, the mechanical key 24 is inserted into the electronic key body 25 from the key hole 42. At this time, the key body portion 242 of the mechanical key 24 passes through the key hole 42 provided in the first case 30 and the second case 40 and enters the electronic key body 25, and enters the guide rails 43 a and 43 b. It will be guided in the case along. Thereby, the 1st case 30 and the mechanical key 24 fit. That is, the first case 30 and the mechanical key 24 are fitted by the second fitting mechanism.

  Finally, as a third step, the mechanical key 24 is completely inserted into the electronic key body 25, whereby the third recess 24 b of the key body 242 of the mechanical key 24 and the third protrusion of the second case 40. 44 is fitted. That is, the second case 40 and the mechanical key 24 are fitted by the third fitting mechanism. In addition, the 3rd projection part 44 is not illustrated in FIG.10, FIG11 and FIG.12.

  Thereby, in the state which inserted the mechanical key 24, the fitting state of the 1st case 30 and the 2nd case 40 does not remove | deviate.
