[0024] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Also, in each figure, each element is exaggerated for ease of explanation.

[0025] In this specification, the width direction of the second unit 20 is defined as the X direction, the depth direction of the second unit 20 is defined as the Y direction, and the thickness direction of the second unit 20 is defined as the Z direction. The Y direction is an example of the second direction in the present disclosure, and the Z direction is an example of the first direction in the present disclosure.

[0026] As shown in FIG. 1, the electronic device 1 is, as an example, a notebook personal computer (laptop PC). The electronic device 1 includes a first unit 10, a second unit 20, and a latch mechanism unit 30 that can hold the first unit 10 in a closed state with respect to the second unit 20. In the closed state, the first unit 10 forms an angle of substantially zero degrees with respect to the second unit 20. The first unit 10 is detachably attached to the second unit 20. That is, the electronic device 1 is configured as a so-called detachable computer.

[0027] The first unit 10 is, for example, a tablet computer. The first unit 10 is in a substantially rectangular plate shape and has a first main surface 10a, a second main surface 10b, and a first side surface 10c. The second main surface 10b is disposed on the side opposite to the first main surface 10a in the thickness direction (e.g., the Y direction) of the first unit 10, and the display unit 11 is provided thereon. The first side surface 10c intersects the first main surface 10a and the second main surface 10b. The display unit 11 is provided on the second main surface 10b. The display unit 11 is, for example, a touch panel capable of receiving a touch operation by the user. The first unit 10 incorporates a central processing unit (CPU), a volatile memory device (RAM), a non-volatile memory device (ROM, SSD, etc.), a battery, and the like. The non-volatile memory device (ROM, SSD, etc.) stores an operating system (OS), various application programs, various data, and the like. The central processing unit (CPU) realizes various functions by reading the OS, application programs, and various data and executing arithmetic processing.

[0028] The second unit 20 is, for example, a station to which the first unit 10 is detachably attached. The second unit 20 is in a substantially rectangular plate shape and has a third main surface 20a, a fourth main surface 20b on the side opposite to the third main surface 20a in the Z direction, and a second side surface 20c intersecting the third main surface 20a and the fourth main surface 20b. Input units 21 and 22 through which the user can perform input processing are provided on the third main surface 20a. The input units 21 and 22 include, for example, a keyboard 21 and a touch pad 22.

[0029] The first unit 10 is attached to the second unit 20 via a hinge 23. The hinge 23 is disposed at an edge of the second unit 20 in the Y direction. The hinge 23 has a rotation axis parallel to the width direction of the electronic device 1. The hinge 23 rotates the first unit 10 around the rotation axis with respect to the second unit 20. The hinge 23 can hold the first unit 10 at various angles with respect to the second unit 20, for example. For example, as shown in FIG. 1, the hinge 23 can hold the first unit 10 at an angle of 90 degrees with respect to the second unit 20. In this case, the first unit 10 is in an open state where it is opened at an angle of 90 degrees with respect to the second unit 20. Also, the hinge 23 can hold the first unit 10 in a closed state with respect to the second unit 20. When the first unit 10 is in the closed state, the second main surface 10b and the third main surface 20a approach and face each other, and the first side surface 10c and the second side surface 20c are arranged along the same plane.

[0030] Subsequently, the configuration of the latch mechanism portion 30 will be described.

[0031] The latch mechanism portion 30 includes a housing recess 40, a coil spring 43, a first groove portion 51, and a latch member 60. In the present embodiment, the housing recess 40 and the latch member 60 are provided on the second side surface 20c of the second unit 20 as shown in FIG. 1. The second side surface 20c constitutes a side surface far from the hinge 23 in the Y direction among the side surfaces intersecting the third main surface 20a and the fourth main surface 20b of the second unit 20. The first groove portion 51 is provided on the first side surface 10c of the first unit 10. The first side surface 10c constitutes a side surface far from the hinge 23 in the Y direction among the side surfaces intersecting the first main surface 10a and the second main surface 10b of the first unit 10. The latch member 60 is configured to be rotatable around a rotation axis L extending in the Y direction between a regulation position P1 (see FIG. 3) and a release position P2 (see FIG. 2) as shown in FIGS. 2 and 3.

[0032] As shown in FIG. 4, the first groove portion 51 is provided on the first side surface 10c of the first unit 10 and is recessed from the first side surface 10c toward the inside of the first unit 10. When the latch member 60 is located at the regulation position P1, the protrusion 66 of the latch member 60 described later is accommodated in the first groove portion 51. At this time, the protrusion 66 is accommodated in a state where both ends in its radial direction are in contact with the first inner surface 51c and the second inner surface 51d that face each other in the radial direction of the first groove portion 51. The first groove portion 51 has a substantially rectangular shape extending along the rotation direction of the latch member 60 (the X direction in the present embodiment).

[0033] In the present embodiment, the first groove portion 51 has a second inclined surface 51a and a fifth inclined surface 51b. A bottom surface extending in the X direction along the first side surface 10c is provided between the second inclined surface 51a and the fifth inclined surface 51b of the first groove portion 51.

[0034] The second inclined surface 51a is provided at an end 51e close to the second unit 20 in the rotation direction of the latch member 60. The second inclined surface 51a is inclined in the Y direction and away from the first side surface 10c as it advances in the rotation direction of the latch member 60 and away from the second unit 20. The fifth inclined surface 51b is provided at an end close to the first unit 10 in the rotation direction of the latch member 60. The fifth inclined surface 51b is inclined in the Y direction and away from the first side surface 10c as it advances in the rotation direction of the latch member 60 and away from the first unit 10.

[0035] As shown in FIG. 4, the accommodation recess 40 is recessed from the second side surface 20c of the second unit 20 in the Y direction and toward the inside of the second unit 20. The accommodation recess 40 has a substantially circular shape when viewed along the Y direction and accommodates the shaft portion 61 of the latch member 60 described later.

[0036] Inside the accommodation recess 40, a substantially cylindrical shaft member 41 extending in the Y direction from the bottom surface of the accommodation recess 40 and approaching the second side surface 20c is provided. A virtual straight line passing through the center of the shaft member 41 and extending in the Y direction when viewed along the Y direction constitutes the rotation axis L of the latch member 60. A gap is provided around the shaft member 41 with respect to the rotation axis L, and the shaft member 41 is accommodated in a recess 62 (described later) of the shaft portion 61 through an opening 63 of the latch member 60 described later. On the end face of the shaft member 41 close to the second side surface 20c in the Y direction, a threaded hole 42 to which a screw 44 (see FIG. 2) is fastened is formed. As shown in FIG. 2, the latch member 60 is screwed to the shaft member 41 via the screw 44. The screw 44 has a substantially circular head 44a when viewed along the Y direction. The head 44a has a diameter larger than the outer diameter of the coil spring 43.

[0037] As shown in FIG. 4, a regulation groove 45 and a second groove portion 52 are provided in the second side surface 20c.

[0038] The regulation groove 45 accommodates a regulation member 64 of the latch member 60 described later. The regulation groove 45 is arranged on the opposite side of the second groove portion 52 described later with respect to the accommodation recess 40 in the second side surface 20c and adjacent to the accommodation recess 40, and is connected to the accommodation recess 40. The regulation groove 45 has a substantially arc shape extending along the opening edge of the accommodation recess 40, and has a first end portion 45a on the first unit 10 side and a second end portion 45b on the second unit 20 side in the rotation direction of the latch member 60 (in other words, the circumferential direction with respect to the rotation axis L). In the present embodiment, the rotation range of the latch member 60 is regulated by the first groove portion 51 and the regulation groove 45.

[0039] The second groove portion 52 is recessed in the Y direction and from the second side surface 20c toward the inside of the second unit 20. The second groove portion 52 is disposed at a position where the first groove portion 51 is rotated approximately 90 degrees counterclockwise when viewed from the direction from the first side surface 10c toward the inside of the first unit 10 in the Y direction. When the latch member 60 is located at the release position P2, the protrusion 66 of the latch member 60 is received in the second groove portion 52. The second groove portion 52 extends along the rotation direction of the latch member 60 (in the Z direction in the present embodiment).

[0040] In the present embodiment, the second groove portion 52 has a fourth inclined surface 52a and a sixth inclined surface 52b. A bottom surface extending in the Z direction along the second side surface 20c is provided between the fourth inclined surface 52a and the sixth inclined surface 52b of the second groove portion 52.

[0041] The fourth inclined surface 52a is provided at an end 52c close to the first unit 10 in the rotation direction of the latch member 60. The fourth inclined surface 52a is inclined in the Y direction and away from the second side surface 20c as it moves away from the first unit 10 in the rotation direction of the latch member 60. The sixth inclined surface 52b is provided at an end close to the second unit 20 in the rotation direction of the latch member 60. The sixth inclined surface 52b is inclined in the Y direction and away from the second side surface 20c as it moves away from the second unit 20 in the rotation direction of the latch member 60.

[0042] The coil spring 43 is housed inside the housing recess 40 and biases the shaft portion 61 in the Y direction and away from the connecting portion 65. The coil spring 43 is an example of a biasing member in the present disclosure. The coil spring 43 is disposed in the gap around the shaft member 41 with respect to the rotation axis L such that the shaft member 41 penetrates through the inside thereof.

[0043] As shown in FIG. 5, the latch member 60 has a shaft portion 61, a connecting portion 65, and a protrusion 66.

[0044] The shaft portion 61 has a cylindrical shape extending along the rotation axis L and is accommodated in the accommodation recess 40 of the second unit 20. A recess 62 having a substantially circular opening 63 is provided on one end surface of the shaft portion 61 in the Y direction. The recess 62 is configured to be able to accommodate the shaft member 41. The opening 63 has a diameter smaller than the diameter of the shaft member 41. The shaft member 41 is accommodated in the recess 62 of the shaft portion 61 through this opening 63.

[0045] The shaft portion 61 has a regulating member 64 protruding in the radial direction. In the present embodiment, the regulating member 64 has a substantially rectangular parallelepiped shape extending along the rotation axis L, is disposed at the end on the opposite side of the recess 62 in the Y direction of the shaft portion 61, and is connected to the connecting portion 65. When the latch member 60 reaches the release position P2 from the regulating position P1, the regulating member 64 contacts the first end portion a45a of the regulating groove 45 of the latch member 60 to prevent the latch member 60 from further rotating beyond the release position P2. Further, when the latch member 60 reaches the regulating position P1 from the release position P2, the regulating member 64 contacts the second end portion 45b of the regulating groove 45 of the latch member 60 to prevent the latch member 60 from further rotating beyond the regulating position P1.

[0046] As an example, the connecting portion 65 has a substantially rectangular plate shape in which the radial direction D1 (see FIG. 5) of the rotation axis L is the longitudinal direction, and the shaft portion 61 is connected to one end in the longitudinal direction. Here, the radial direction D1 of the rotation axis L is a direction orthogonal to the rotation axis L. As shown in FIGS. 2 and 3, the tip 65b far from the rotation axis L in the radial direction of the connecting portion 65 has a shape inclined in the radial direction and approaching the rotation axis L as it advances in the rotation direction of the latch member 60 and away from the second unit 20 when the protrusion 66 is located near the regulating position P1. The connecting portion 65 has an opposing surface 65a opposing the first side surface 10c and the second side surface 20c in the Y direction. The opposing surface 65a opposes the first side surface 10c in the Y direction when the latch member 60 is located at the regulating position P1, and opposes the second side surface 20c in the Y direction when the latch member 60 is located at the release position P2.

[0047] As shown in FIG. 5, the latch member 60 has a protrusion 66 provided at the tip 65b of the connecting portion 65. The protrusion 66 protrudes from the opposing surface 65a in the Y direction and toward the first side surface 10c or the second side surface 20c. In the present embodiment, the protrusion 66 is plate-shaped and extends along the rotation direction of the latch member 60.

[0048] The protrusion 66 has a first inclined surface 66a and a third inclined surface 66b at both ends in the rotation direction of the latch member 60, respectively. Further, the protrusion 66 has a flat surface 66e located between the first inclined surface 66a and the third inclined surface 66b. The flat surface 66e is a plane parallel to the opposing surface 65a of the connecting portion 65. That is, the protrusion 66 has a substantially trapezoidal shape when viewed along the radial direction. The first inclined surface 66a is provided at an end 66f (an example of the first end) close to the second unit 20 in the rotation direction of the latch member 60. The first inclined surface 66a is inclined in the Y direction and away from the opposing surface 65a as it moves away from the second unit 20 in the rotation direction of the latch member 60. The third inclined surface 66b is provided at an end 66g (an example of the second end) close to the first unit 10 in the rotation direction of the latch member 60. The third inclined surface 66b is inclined in the Y direction and away from the opposing surface 65a as it moves away from the first unit 10 in the rotation direction of the latch member 60. As described above, by having the protrusion 66 have a substantially trapezoidal shape, the latch member 60 can be rotated smoothly. As shown in FIG. 5, the ends 66f and 66g of the protrusion 66 face each other.

[0049] As an example, when the protrusion 66 is accommodated in the first groove portion 51, the first inclined surface 66a of the protrusion 66 contacts the second inclined surface 51a of the first groove portion 51, and the third inclined surface 66b of the protrusion 66 contacts the fifth inclined surface 51b of the first groove portion 51. When the protrusion 66 is accommodated in the second groove portion 52, the first inclined surface 66a of the protrusion 66 contacts the sixth inclined surface 52b of the second groove portion 52, and the third inclined surface 66b of the protrusion 66 contacts the fourth inclined surface 52a of the second groove portion 52.

[0050] The protrusion 66 has a first outer surface 66c and a second outer surface 66d that extend in the Y direction from the opposing surface 65a and away from the opposing surface 65a. The first outer surface 66c is located closer to the rotation axis L than the second outer surface 66d in the radial direction. In a state where the protrusion 66 is accommodated in the first groove portion 51, the first outer surface 66c of the protrusion 66 contacts the first inner surface 51c of the first groove portion 51, and the second outer surface 66d of the protrusion 66 contacts the second inner surface 51d of the first groove portion 51.

[0051] Subsequently, the operation when the first unit 10 is opened and closed with respect to the second unit 20 will be described.

[0052] When the latch member 60 is located at the regulation position P1, as shown in FIG. 3, the protrusion 66 is accommodated in the first groove portion 51, and the first unit 10 is held in a closed state with respect to the second unit 20 by the latch member 60. When changing the first unit 10 from the closed state to the open state with respect to the second unit 20, first, the latch member 60 located at the regulation position P1 is rotated to the release position P2. Then, the first unit 10 is rotated until it forms a desired angle with respect to the second unit 20. When closing the first unit 10 in the open state with respect to the second unit 20, contrary to the above-described release operation, first, the first unit 10 in the open state is rotated with respect to the second unit 20 to the closed state. Then, the latch member 60 located at the release position P2 is rotated to the regulation position P1.

[0053] According to the electronic device 1 of the present embodiment, the following effects can be achieved.

[0054] The electronic device 1 includes a first unit 10, a second unit 20 rotatably connected to the first unit 10, and a latch mechanism unit 30 that can hold the first unit 10 in a closed state with respect to the second unit 20. The latch mechanism unit 30 has a latch member 60, a housing recess 40, a coil spring 43, and a first groove portion 51. The latch member 60 has a shaft portion 61 extending along a rotation axis L extending in the Y direction, a connecting portion 65 extending radially with respect to the rotation axis L from the shaft portion 61, and a protrusion 66 provided at a tip 65b of the connecting portion 65 farther from the shaft portion 61 in the radial direction. The latch member 60 is attached to the second unit 20 in a state where it can rotate around the rotation axis L between a regulation position P1 where the protrusion 66 faces the first side surface 10c in the Y direction and a release position P2 where the protrusion 66 faces the second side surface 20c in the Y direction. The housing recess 40 is provided in the second side surface 20c and houses the shaft portion 61. The coil spring 43 is disposed in the housing recess 40 and biases the latch member 60 in the Y direction and toward the inside of the first unit 10. The first groove portion 51 is provided in the first side surface 10c and houses the protrusion 66 when the latch member 60 is located at the regulation position P1. The protrusion 66 has a first inclined surface 66a provided at an end closer to the second unit 20 in the rotation direction of the latch member 60 when the latch member 60 is located at the regulation position P1. The first inclined surface 66a is inclined in the Y direction and in a direction approaching the first side surface 10c as it moves away from the second unit 20 in the rotation direction of the latch member 60. With such a configuration, simply rotating the latch member 60 located at the regulation position P1 toward the release position P2 can release the holding of the closed state of the first unit 10 with respect to the second unit 20. That is, when releasing the holding of the closed state of the first unit 10 with respect to the second unit 20, it is not necessary to move the protrusion 66 in the Y direction and against the biasing force. As a result, an electronic device 1 that can more easily release the holding of the closed state of the first unit 10 with respect to the second unit 20 can be realized.

[0055] The first groove portion 51 has a second inclined surface 51a provided at an end closer to the second unit 20 in the rotational direction of the latch member 60. The second inclined surface 51a is inclined in the Y direction and away from the first side surface 10c as it moves away from the second unit 20 in the rotational direction of the latch member 60. With such a configuration, the latch member 60 located at the regulation position P1 can be easily rotated toward the release position P2.

[0056] The tip 65b of the connecting portion 65 is inclined in the radial direction and toward the rotation axis L as it moves away from the second unit 20 in the rotational direction of the latch member 60 when the protrusion 66 is located near the regulation position P1. With such a configuration, when the first unit 10 is in the open state and the latch member 60 is located at the regulation position P1 instead of the release position P2, when the first unit 10 is changed from the open state to the closed state, even if the latch member 60 contacts the first unit 10, it is not pushed in the radial direction and is easily rotated toward the release position P2. As a result, damage to the latch member 60 can be prevented.

[0057] A second groove portion 52 for accommodating the protrusion 66 is provided on the second side surface 20c when the latch member 60 is located at the release position P2. The protrusion 66 has a third inclined surface 66b provided at an end closer to the first unit 10 in the rotational direction of the latch member 60. The third inclined surface 66b is inclined in the Y direction and toward the second side surface 20c as it moves away from the first unit 10 in the rotational direction of the latch member 60. With such a configuration, when the latch member 60 is located at the release position P2, the protrusion 66 can be accommodated in the second groove portion 52. Also, the latch member 60 located at the release position P2 can be rotated more easily toward the regulation position P1.

[0058] The second groove portion 52 has a fourth inclined surface 52a provided at an end closer to the first unit 10 in the rotational direction of the latch member 60. The fourth inclined surface 52a is inclined in the Y direction and away from the second side surface 20c as it moves away from the first unit 10 in the rotational direction of the latch member 60. With such a configuration, the latch member 60 located at the release position P2 can be rotated more easily toward the regulation position P1.

[0059] When the latch member 60 is located at the regulation position P1, the protrusion 66 is received in the first groove portion 51 with the first outer surface 66c and the second outer surface 66d of the protrusion 66 in contact with the first inner surface 51c and the second inner surface 51d of the first groove portion 51. With such a configuration, it is possible to prevent the latch member 60 from rotating beyond the regulation position P1.

[0060] Note that the first groove portion 51 can adopt any shape and configuration capable of accommodating the protrusion 66. For example, in the present embodiment, an example in which the first groove portion 51 has a second inclined surface 51a and a fifth inclined surface 51b has been described, but it is not limited thereto. For example, either one or both of the second inclined surface 51a and the fifth inclined surface 51b may be omitted.

[0061] The protrusion 66 is not limited to having a third inclined surface 66b, and the third inclined surface 66b may be omitted. Also, a gap may be formed between both ends of the protrusion 66 in the radial direction and the inner surface of the first groove portion 51.

[0062] The latch mechanism portion 30 is not limited to being provided on the first side surface 10c of the first unit 10 and the second side surface 20c of the second unit 20. It may be provided on any side surface arranged along the same plane of the first unit 10 and the second unit 20.

[0063] The first unit 10 may be a station and the second unit 20 may be a tablet.

[0064] In this embodiment, an example has been described in which when the protrusion 66 is located near the regulation position P1, the tip 65b of the connecting portion 65 inclines in the radial direction and in the direction approaching the rotation axis L as it moves away from the second unit 20 in the rotation direction of the latch member 60. However, the tip 65b does not necessarily have to be inclined as described above.

[0065] In this embodiment, an example in which the second groove portion 52 is provided on the second side surface 20c has been described, but the present invention is not limited to this. For example, the second groove portion 52 may be omitted.

[0066] The biasing member is not limited to the case where it is constituted by the coil spring 43, and other configurations capable of biasing the latch member 60 in the Y direction and toward the inside of the second unit 20 can be adopted.

[0067] The second groove portion 52 is not limited to the case where it has the fourth inclined surface 52a and the sixth inclined surface 52b, and either one or both of the fourth inclined surface 52a and the sixth inclined surface 52b may be omitted.

[0068] Although the present disclosure has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various modifications and variations will be apparent to those skilled in the art. Such modifications and variations are to be understood as being included therein as long as they do not depart from the scope of the present disclosure as defined by the appended claims.
