  As shown in FIG. 2, the mechanical key 200 includes a metal key plate 210 and a resin gripping portion 220. The key plate 210 is an example of the “insertion portion” in the present invention, and is a portion that is inserted into a keyhole of a vehicle lock. The gripping part 220 supports the base part of the key plate 210 and is a part that is gripped by the user when the mechanical key 200 is used.

  The gripping part 220 includes an accommodation part 221 and an exposure part 222. The accommodating part 221 is a part accommodated in the 1st opening part 102 (refer FIG. 3 and FIG. 4) of the housing | casing 100, when the mechanical key 200 is inserted in the housing | casing 100. FIG. The accommodating portion 221 has a rectangular parallelepiped shape in accordance with the space shape of the first opening portion 102.

  A protrusion 223 that can be inserted into a concave groove 104 (see FIG. 6) formed in the front surface 100B of the housing 100 is formed on the left side surface 221A (the side surface on the Y axis positive side in the drawing) of the housing portion 221. ing. The protrusion 223 is used to divide the housing 100 into upper and lower parts when performing battery replacement or the like. The details of the protrusion 223 will be described later with reference to FIG.

  The exposed portion 222 is a portion that is exposed from the housing 100 when the mechanical key 200 is inserted into the housing 100. As shown in FIG. 1, the exposed portion 222 has a shape that forms the tip portion of the housing 100 when the mechanical key 200 is inserted into the housing 100.

  FIG. 3 is a perspective view showing configurations of the front surface 100B and the bottom surface 100C of the housing 100 according to the embodiment. FIG. 4 is a plan view showing the configuration of the bottom surface 100C of the housing 100 according to the embodiment. FIG. 4A shows a state where the mechanical key 200 is not inserted. FIG. 4B shows a state in which the mechanical key 200 is inserted.

  As shown in FIGS. 3 and 4A, a first opening 102 is formed at the bottom of the housing 100, in which a part of the front surface 100 </ b> B and a part of the bottom surface 100 </ b> C are cut out. The first opening 102 has a rectangular parallelepiped shape in accordance with the outer shape of the housing part 221 housed in the first opening 102. A rectangular second opening 103 for inserting the key plate 210 of the mechanical key 200 into the housing 100 is formed in the back wall 102 a of the first opening 102.

  As shown in FIG. 4B, when the mechanical key 200 is inserted into the housing 100 from the front surface 100B side of the housing 100, the housing portion 221 of the mechanical key 200 forms a part of the bottom surface 100C. And accommodated in the first opening 102. At this time, the key plate 210 of the mechanical key 200 is inserted into the housing 100 through the second opening 103 of the back wall 102a.

[Configuration of casing 100]
FIG. 5 is an exploded perspective view showing the configuration of the housing 100 according to the embodiment. As shown in FIG. 5, the housing 100 is configured such that an upper case 110 and a lower case 120 made of resin can be divided. The upper case 110 is an example of the “first case portion” in the present invention. The upper case 110 is provided with the push buttons 101a to 101c described in FIG.

  The lower case 120 is an example of the “second case portion” in the present invention. The lower case 120 is provided with an electronic circuit 121 for controlling the operation of the electronic key 10. The electronic circuit 121 includes a processor, a memory, a communication antenna, and the like in addition to the switches 122a to 122c corresponding to the push buttons 101a to 101c. In the lower case 120, a battery 123 for driving the electronic circuit 121 is accommodated on the back side of the electronic circuit 121. A plurality of protrusions 124 are formed on the upper edge of the lower case 120 along the upper edge. Each of the plurality of protrusions 124 engages with a protrusion 111 formed on the lower edge and inside of the upper case 110. As a result, the housing 100 can maintain a state in which the upper case 110 and the lower case 120 are coupled to each other.

  For example, when replacing the battery 123 built in the housing 100, it is necessary to divide the upper case 110 and the lower case 120 as shown in FIG. At this time, in order to release the engagement between the protrusion 111 of the upper case 110 and the protrusion 124 of the lower case 120, it is necessary to push the space between the upper case 110 and the lower case 120. As described above, there is a risk that the case 100 and the electronic circuit 121 may be damaged by the conventional method using a minus driver or the like. In the electronic key 10 of the present embodiment, the concave groove 104 is provided in the casing 100, and the protrusion 223 is provided in the mechanical key 200, so that the upper case can be easily and reliably produced without causing such a problem. 110 and the lower case 120 can be divided. Hereinafter, this point will be specifically described.

[Configuration of concave groove 104]
FIG. 6 is a plan view showing the configuration of the front surface 100B of the housing 100 according to the embodiment. As shown in FIG. 6, on the front surface 100 </ b> B of the housing 100, the horizontal width direction (Y-axis direction in the drawing) of the housing 100 is set at the upper case 110 side and at the division position of the upper case 110 and the lower case 120. A rectangular groove 104 is formed in the longitudinal direction. A similarly rectangular projection 223 (see FIG. 7) formed on the left side 221A of the accommodating portion 221 of the mechanical key 200 can be inserted into the concave groove 104.

  Here, the central portion of the front surface 100B in the lateral width direction has a relatively thin wall surface, and it is difficult to form the concave groove 104 so as to have sufficient strength. Further, as shown in FIG. 6, the central portion is formed with a protrusion 106 that engages with a groove 224 (see FIG. 2) formed in the exposed portion 222 of the mechanical key 200. If the groove 104 is formed in the portion, the left side surface 221A on which the protrusion 223 is formed interferes with the protrusion 106 when the protrusion 223 of the mechanical key 200 is inserted into the groove 104. The protrusion 223 cannot be reliably inserted into the concave groove 104.

  Therefore, in the casing 100 of the present embodiment, as shown in FIG. 6, the concave groove 104 is formed in the front surface 100 </ b> B at a position offset to the outside (Y axis positive side in the drawing) from the central portion in the lateral width direction. ing. Thereby, the housing 100 according to the present embodiment can form the concave groove 104 having sufficient strength, and can reliably insert the protruding portion 223 into the concave groove 104. . However, depending on the product, there may be a case where the wall surface has a sufficient thickness at the central portion in the width direction of the front surface 100B, and the protrusion 106 is not formed. In such a case, the groove 104 may be formed in the central portion, not limited to the configuration of the present embodiment.

  The formation position of the concave groove 104 is not limited to the front surface 100B. However, the front surface 100B is hidden by the exposed portion 222 of the mechanical key 200 when the electronic key 10 is in normal use (when the mechanical key 200 is inserted into the housing 100 as shown in FIG. 1). Therefore, as in the present embodiment, by forming the concave groove 104 on the front surface 100B, the concave groove 104 can be made inconspicuous during normal use of the electronic key 10.

  Further, in this embodiment, the concave groove 104 is formed on the upper case 110 side, but the concave groove 104 may be formed on the lower case 120 side. Further, in the present embodiment, only one concave groove 104 is provided at the division position of the casing 100, but a plurality of concave grooves 104 may be provided at the division position of the casing 100.

[Configuration of mechanical key 200]
FIG. 7 is a trihedral view showing the configuration of the mechanical key 200 according to one embodiment. 7A is a plan view of the mechanical key 200. FIG. FIG. 5B is a left side view of the mechanical key 200. FIG. 2C is a rear view of the mechanical key 200. FIG.

  As shown in FIG. 7, the left side surface 221A of the accommodating portion 221 of the mechanical key 200 is formed with a protruding portion 223 that protrudes toward the outside (Y-axis positive side in the drawing) in the lateral width direction (Y-axis direction in the drawing). Has been. The protrusion 223 has a rectangular cross-sectional shape, and can be inserted into the same rectangular groove 104 (see FIG. 6) formed on the front surface 100 </ b> B of the housing 100. A chamfering process is applied to the tip edge portion of the protruding portion 223 so that the protruding portion 223 can be easily inserted into the concave groove 104.

  Here, the suitable size of the projection part 223 is demonstrated. First, the width W2 in the longitudinal direction of the protrusion 223 is at least shorter than the width W1 in the longitudinal direction of the groove 104 (see FIG. 6) so that the protrusion 223 can be inserted into the groove 104. Need to be. Similarly, the length L2 of the protrusion 223 in the short direction needs to be at least shorter than the length L1 of the concave groove 104 in the short direction (see FIG. 6). However, in order to suppress the rattling of the protrusion 223 in the concave groove 104, the difference between the width W2 and the length L2 of the protrusion 223 and the width W1 and the length L1 of the concave groove 104 (that is, the protrusion The clearance between the portion 223 and the groove 104 is preferably as small as possible.

  Further, the width W2 of the protrusion 223 is at least the length of the groove 104 so that the protrusion 223 can push the groove 104 up and down when the protrusion 223 rotates in the groove 104. It is necessary to be at least L1. In particular, the width W2 of the protrusion 223 is concave until the engagement between the protrusion 111 of the upper case 110 and the protrusion 124 of the lower case 120 is released when the protrusion 223 rotates in the groove 104. It is preferable that the length is such that the groove 104 can be sufficiently expanded in the vertical direction.

  Further, when the protrusion 223 is inserted into the concave groove 104, the left side surface 221A on which the protrusion 223 is formed is brought into close contact with the front surface 100B on which the concave groove 104 is formed to function as a mechanical stopper. The height H2 in the protruding direction of the protrusion 223 is preferably equal to or less than the depth D1 in the depth direction of the concave groove 104 (see FIG. 10).

  Next, the suitable formation position of the projection part 223 is demonstrated. First, the protrusion 223 is formed on the left side surface 221A, which is the surface on the side where the key plate 210 is offset. Accordingly, when the protrusion 223 is inserted into the concave groove 104 and the mechanical key 200 is rotated, the protrusion 223 is rotated at a position relatively close to the center of gravity of the mechanical key 200 (a position having a relatively high strength). Can be made. Therefore, the rotation operation of the mechanical key 200 can be performed stably.

  Further, the protrusion 223 is formed at the end on the key plate 210 side (that is, a position offset toward the key plate 210 (a position offset from the center)) on the left side 221A. Accordingly, the rotation center axis when the protrusion 223 is inserted into the concave groove 104 and the mechanical key 200 is rotated is set to a position relatively close to the center in the longitudinal direction (X-axis direction in the drawing) of the mechanical key 200. be able to. Therefore, the rotation operation of the mechanical key 200 can be performed stably. Further, when the mechanical key 200 is rotated, the size of the circle formed by the locus of the left side surface 221A can be made relatively large. That is, when the mechanical key 200 is rotated, the contact area of the left side surface 221A with respect to the front surface 100B can be increased, so that the rotation operation of the mechanical key 200 can be performed stably.

  Further, the protrusion 223 is formed at the upper end portion (that is, the position offset upward) in the height direction (Z-axis direction in the drawing) of the left side surface 221A. Accordingly, as will be described in detail with reference to FIG. 13, when the mechanical key 200 is inserted into the housing 100, the slide groove 105 for sliding the protrusion 223 is relatively centered in the vertical direction of the housing 100. It can be formed in a close position.

  Further, the protrusion 223 is formed at the above-described formation position, so that the protrusion 223 is formed on the front surface 100B of the housing 100 when the protrusion 223 is inserted into the concave groove 104 and the mechanical key 200 is rotated. It can avoid that the projection part 106 interferes with the mechanical key 200 (refer FIGS. 9-11).

  In addition, the protrusion part 223 should just be formed in the position of not only said formation position but at least the outer surface of the mechanical key 200. FIG. For example, the protrusion 223 may be formed on the right side 221B, which is the side opposite to the side where the key plate 210 is offset. In the mechanical key 200, the right side surface 221 </ b> B far from the key plate 210 is more likely to be loose in the housing 100 than the left side surface 221 </ b> A near the key plate 210. Therefore, by forming the protrusion 223 on the right side 221B, the effect of preventing the mechanical key 200 from shaking in the housing 100 can be further enhanced. In this case, the slide groove 105 needs to be formed at a position opposite to the position shown in FIGS. 6 and 13 in the lateral width direction of the housing 100. Further, the protrusions 223 may be formed on both the left side 221A and the right side 221B. In this case, the rattling prevention effect of the mechanical key 200 can be further enhanced. In this case, the slide groove 105 needs to be formed in both the position shown in FIGS. 6 and 13 and the position opposite to the position shown in FIGS. 6 and 13 in the lateral width direction of the housing 100.

  Next, a suitable material for the protrusion 223 will be described. In the present embodiment, the protrusion 223 is formed integrally with the accommodating portion 221 in the mechanical key 200. That is, the protrusion 223 is made of a resin material, like the housing 221 and the recessed groove 104. As a result, the hardness of the protruding portion 223 and the hardness of the recessed groove 104 are relatively close, so that when the protruding portion 223 is rotated in the recessed groove 104, the erosion of the recessed groove 104 by the protruding portion 223 is suppressed. can do. However, the protrusions 223 may be made of a material other than resin (for example, metal).

[Procedure for dividing the housing 100]
Next, with reference to FIGS. 8-12, the procedure of the division | segmentation operation | work of the housing | casing 100 using the mechanical key 200 is demonstrated.

(First procedure)
FIG. 8 is a diagram for explaining a procedure (first procedure) of dividing work of the housing 100 according to the embodiment. First, as shown in FIG. 8, the mechanical key 200 is pulled out from the housing 100 to expose the front surface 100 </ b> B of the housing 100. Then, as illustrated in FIG. 8, the protrusion 223 formed on the left side 221 </ b> A of the mechanical key 200 is opposed to the concave groove 104 formed on the front surface 100 </ b> B of the housing 100.

(Second procedure)
FIG. 9 is a diagram for explaining a procedure (second procedure) of dividing work of the housing 100 according to the embodiment. FIG. 10 is an enlarged view showing a state in which the protrusion 223 is inserted into the recessed groove 104 of the housing 100 according to the embodiment. Next, as shown in FIGS. 9 and 10, the protrusion 223 is inserted into the concave groove 104. At this time, the left side surface 221A of the mechanical key 200 is pressed against the front surface 100B of the housing 100 as shown in FIG. Thereby, the protrusion part 223 can be made into the state inserted in the ditch | groove 104 reliably.

  Here, as shown in FIG. 10B, the height H <b> 2 of the protrusion 223 is shorter than the depth D <b> 1 of the concave groove 104. For this reason, as shown in FIG. 10B, the left side surface 221 </ b> A can be brought into close contact with the front surface 100 </ b> B in a state where the protruding portion 223 is inserted into the concave groove 104. Thereby, the mechanical key 200 can be stabilized with respect to the housing | casing 100. FIG.

  Further, even if the left side surface 221A is pressed relatively strongly against the front surface 100B, the left side surface 221A functions as a mechanical stopper, so that the protrusion 223 does not reach the back wall of the concave groove 104. The protrusion 223 does not damage the inner wall of the recessed groove 104 or the electronic components inside the housing 100.

(Third procedure)
FIG. 11 is a diagram for explaining a procedure (third procedure) of dividing work of the housing 100 according to the embodiment. Next, as shown in FIG. 11, the mechanical key 200 is rotated counterclockwise (in the direction of arrow B in the figure) using the protrusion 223 inserted into the concave groove 104 as the rotation center axis. Thereby, the projection part 223 rotates in the concave groove 104, and pushes the concave groove 104 up and down. As a result, the space between the upper case 110 and the lower case 120 is expanded, and along with this, when the engagement between the protrusion 111 of the upper case 110 and the protrusion 124 of the lower case 120 is released, The upper case 110 and the lower case 120 are divided.

(Operation of the protrusion 223 in the concave groove 104)
FIG. 12 is a conceptual diagram for explaining the operation of the protrusion 223 in the concave groove 104 of the housing 100 according to the embodiment. In FIG. 12, the section of the protrusion 223 is shown.

  FIG. 12A shows a state where the protrusion 223 is inserted into the concave groove 104 (a state corresponding to FIG. 9). Here, when the concave groove 104 and the protruding portion 223 have substantially the same size, at least one of the upper surface and the lower surface of the protruding portion 223 is the upper wall 104A or the upper edge portion 120A at the time of FIG. There is a case where it is in a state of contacting with.

  Next, as described with reference to FIG. 11, when the mechanical key 200 is rotated counterclockwise (in the direction of arrow B in the figure), as shown in FIG. The upper surface of the protrusion 223 is pressed against the upper wall 104A of the concave groove 104 formed in the upper case 110, and the lower surface of the protrusion 223 is pressed against the upper edge 120A of the lower case 120. .

  Further, when the mechanical key 200 is rotated counterclockwise, the upper surface of the protrusion 223 pushes the upper case 110 upward (in the direction of arrow C in the drawing) as shown in FIG. The lower surface of 223 pushes the lower case 120 downward (in the direction of arrow D in the figure). As a result, the space between the upper case 110 and the lower case 120 is expanded, and when the engagement between the protrusion 111 of the upper case 110 and the protrusion 124 of the lower case 120 is released, 110 and the lower case 120 are divided.

  Here, as shown in FIG. 12, it is preferable that the concave groove 104 and the protrusion 223 have substantially the same shape and the same size. That is, it is preferable that the clearance between the concave groove 104 and the protrusion 223 is extremely small (or zero). Thereby, the ratchet of the protrusion 223 in the groove 104 is hardly generated, and the groove 104 can be pushed up and down in a relatively wide area on the upper and lower surfaces of the protrusion 223. . For this reason, the rotational force of the mechanical key 200 can be efficiently transmitted to the concave groove 104, and the concave groove 104 can be easily and reliably pushed up and down without damaging the concave groove 104.

[Configuration of slide groove 105]
Next, the slide groove 105 formed in the housing 100 will be described with reference to FIG. FIG. 13 is a plan view showing the configuration of the front surface 100B of the housing 100 (with the mechanical key 200 inserted) according to an embodiment. In FIG. 13, the mechanical key 200 shows a cross section of the accommodating portion 221 and the protruding portion 223.

  As shown in FIG. 13, the lower case 120 of the housing 100 has a rectangular opening shape for accommodating the accommodating portion 221 of the mechanical key 200 while sliding in the depth direction (X-axis negative direction in the figure). The first opening 102 is formed. Further, in the lower case 120, a slide that is notched outward (Y-axis positive side in the figure) along the depth direction (X-axis negative direction in the figure) at the upper end of the left side wall 102B of the first opening 102. A groove 105 is formed. The slide groove 105 is formed so that the protrusion 223 formed on the left side surface 221A of the housing portion 221 is also slid in the depth direction when the housing portion 221 is housed in the first opening 102 while sliding. Has been.

  As described above, by providing the slide groove 105, it is possible to avoid the protrusion 223 from interfering with the housing 100 when the accommodating portion 221 is slid. In addition, in the state where the mechanical key 200 is inserted into the housing 100, the movement of the mechanical key 200 in the housing 100 is restricted by the protrusions 223, so that the rattling of the mechanical key 200 can be suppressed. it can. Therefore, it is preferable that the clearance between the protrusion 223 and the slide groove 105 is relatively small.

  In the present embodiment, the slide groove 105 is formed at a position relatively close to the center of the housing 100 in the vertical direction (Z-axis direction in the drawing). Thereby, compared with the case where the slide groove | channel 105 is formed in another position, the rattling suppression effect of the mechanical key 200 can be heightened more. Further, since the slide groove 105 can be formed at a position relatively close to the upper edge portion of the lower case 120, the slide groove 105 is easily formed as compared with the case where the slide groove 105 is formed at another position. can do. Further, as shown in FIG. 13, the size of the casing 100 in the horizontal width direction (Y-axis direction in the figure) becomes larger as it is closer to the center in the vertical direction. Thus, it becomes easy to secure a space for the slide groove 105.

  As shown in FIG. 13, the upper opening surface of the lower case 120 is covered with a plate-like intermediate case portion 130 that is detachably attached to the lower case 120. The intermediate case portion 130 functions as an upper wall of the first opening 102 and the slide groove 105. That is, since it is not necessary to form the upper wall of the first opening 102 and the slide groove 105 in the lower case 120 itself, the first opening 102 and the slide groove 105 are easily formed in the lower case 120. be able to.

  Further, in the present embodiment, by providing a restricting portion (for example, a protruding portion, a narrow width portion, etc.) that restricts the sliding of the protruding portion 223 in the slide groove 105, it is in a state of being accommodated in the housing 100. The mechanical key 200 may be configured not to easily fall off from the casing 100 unless a certain amount of pulling force is applied. That is, the protrusion 223 may further function as a means for preventing the mechanical key 200 from falling off.

  As described above, according to the present embodiment, the protrusion 223 formed on the mechanical key 200 is inserted into the concave groove 104 formed at the division position of the housing 100 to rotate the mechanical key 200. Thus, the housing 100 can be divided into the upper case 110 and the lower case 120. In particular, since the protruding portion 223 has an appropriate shape and size (that is, a shape dedicated to the recessed groove 104) with respect to the recessed groove 104, by using such a protruded portion 223, the casing 100 is formed. It is possible to divide easily and reliably without damage. Further, since the protrusion 223 is provided for the mechanical key 200 that is always mounted on the casing 100, the casing 100 can be immediately disassembled without having to search for a separate instrument when necessary. .

  The embodiments of the present invention have been described in detail above, but the present invention is not limited to these embodiments, and various modifications or changes can be made within the scope of the gist of the present invention described in the claims. It can be changed.

  For example, in the above-described embodiment, an example in which the present invention is applied to an electronic key in which a mechanical key can be inserted into and removed from the casing has been described. It is also possible to apply to an electronic key configured to be detachable. In the above embodiment, the example in which the present invention is applied to an electronic key in which the key plate is offset in the lateral width direction has been described. However, the present invention is applied to an electronic key in which the key plate is not offset in the lateral width direction. It is also possible to do. The present invention is not limited to an electronic key, and can be applied to any portable device as long as the portable device includes at least a mechanical key.

  Moreover, in the said embodiment, although the example which distribute | arranged the groove to the division | segmentation position of a 1st case part and a 2nd case part was demonstrated, it is a 1st case part and a 2nd case part, Comprising: It is also possible to adopt a structure in which at least one of the opposing surface sides is cut out to form a concave groove so that the protrusion of the mechanical key can be inserted.
