Description

  The present invention relates to an electronic device.

  Conventionally, an electronic device including a first housing and a second housing rotatably supported by the first housing has been known.

JP 2009-43098 A

  In this type of electronic apparatus, for example, it is beneficial if a new configuration in which the first housing mounted on the mounting section is easily suppressed from rattling can be obtained.

  Therefore, one of the objects of the present invention is to obtain an electronic device having a novel configuration in which rattling of the first housing mounted on the mounting portion is easily suppressed.

An electronic device according to a first aspect of the present invention includes a first housing including a first member including a first surface, and a second member including a second surface opposite to the first surface, A second housing having a third surface facing the second surface, the second housing being supported by the first housing so as to be rotatable about a rotation center axis with respect to the first housing, and a retaining member; A cylindrical portion protruding in a first direction from the one of the first member and the second member to the other is provided on one inner surface of the first member and the second member; The other of the first member and the second member has a wall provided with a through hole in which the cylindrical portion is inserted and the diameter of which is larger than the outer diameter of the cylindrical portion. And a head that is connected to the shaft, overlaps a tip end surface of the tube, and prevents the wall from coming off from the tube. . The first housing includes a first end separated from the rotation center axis, and a second end provided on the rotation center axis side with respect to the first end. The body has a third end separated from the rotation center axis and a fourth end provided on the rotation center axis side with respect to the third end, and the second surface and the third end are provided. The second housing is rotatable between a first position where the first surface is opposed to a second surface and a second position where the second surface and the third surface are not opposed to each other. And a second support member, which is provided near the first end and spaced apart from each other in the axial direction of the rotation center axis and protrudes from the first surface. The portion has a protrusion protruding in a direction from the third end to the fourth end, and the first housing is flat when the second housing is located at the second position. If it is location, three positions between the convex portion and the two said supporting member is in contact with the plane.

According to such a configuration, for example, since the wall can be moved in the orthogonal direction orthogonal to the first direction, when the first housing is placed on the placing portion, the first member and the second member are moved. Even if the first member and the second member are distorted by an external force, the first member and the second member can relatively move in the orthogonal direction orthogonal to the first direction according to the distortion. Therefore, rattling of the first housing is easily suppressed.
Further, according to such a configuration, for example, since the convex portion is provided at the fourth end, even if the first housing or the second housing has an assembly variation or a shape variation, the first housing or the second housing may have a variation. When the body is placed on a flat surface, the convex portion contacts the flat surface at the fourth end. Therefore, when the first housing is placed on a flat surface with the second housing positioned at the second position, rattling of the first housing is likely to be suppressed.

  In the electronic device, for example, the height of the protrusion gradually increases toward the center of the fourth end in the axial direction of the rotation center axis.

  According to such a configuration, for example, when the first housing is placed on a flat surface, the contact between the projection and the flat surface is close to a point contact. Therefore, rattling of the first housing is more easily suppressed.

  Further, in the electronic device, for example, a tip end surface of the projection is a curved surface.

  According to such a configuration, for example, since the distal end surface of the convex portion is a curved surface, a flat surface that contacts the convex portion is not easily damaged.

Electronic equipment according to a second aspect of the present invention includes a first housing having a first member, and a second member including a second side opposite the first surface including a first surface, A second housing having a third surface facing the second surface and supported by the first housing so as to be rotatable about a rotation center axis with respect to the first housing; A cylindrical portion protruding in a first direction from one of the first member and the second member toward the other is provided on one inner surface of the first member and the second member; The other of the first member and the second member has a wall provided with a through-hole in which the cylindrical portion is inserted and the diameter of which is larger than the outer diameter of the cylindrical portion. And a head connected to the shaft and overlapped with a tip end surface of the cylindrical portion to prevent the wall from coming off from the cylindrical portion. . The first housing is provided with a plurality of support members, each of which has elasticity and protrudes from the first surface, and one of the plurality of support members is different from the other of the support members. Also, the height from the first surface is high and easily elastically deformed.

According to such a configuration, for example, since the wall can be moved in the orthogonal direction orthogonal to the first direction, when the first housing is placed on the placing portion, the first member and the second member are moved. Even if the first member and the second member are distorted by an external force, the first member and the second member can relatively move in the orthogonal direction orthogonal to the first direction according to the distortion. Therefore, rattling of the first housing is easily suppressed.
Further, according to such a configuration, for example, even if there is such deviation between the shape variation or shape center of gravity position of the first housing when the first housing is placed on the plane, One A plurality of support members can contact a plane by elastically deforming one support member. Therefore, rattling of the first housing is easily suppressed.

  In the electronic device, for example, the one support member is provided with a space.

  According to such a configuration, for example, the ease of elastic deformation of one support member is easily increased. Further, the weight of one support member can be reduced.

  In the electronic device, for example, at least one of the one support member and the first housing is provided with a vent that communicates with the space.

According to such a configuration, for example, when the support member is elastically deformed, the air in the space is exhausted from the ventilation port, so that the support member is easily elastically deformed.
In the electronic device, for example, the wall is provided movably along the first direction with respect to the one of the first member and the second member.
According to such a configuration, for example, since the wall is provided so as to be movable along the first direction, the first member and the second member are provided when the first housing is mounted on the mounting portion. Even if is distorted due to an external force, the first member and the second member can relatively move along a direction orthogonal to the first direction or along the first direction according to the distortion. Therefore, rattling of the first housing is more easily suppressed.
Further, in the electronic device, for example, the one of the first member and the second member is located at an interval from the head in a direction opposite to the first direction with respect to the head, A restriction is provided to restrict movement of the wall in the opposite direction by contacting the wall.
According to such a configuration, for example, the limiter limits the movement of the wall in the opposite direction, so that the amount of movement of the wall can be limited.

  According to the above aspect of the invention, it is possible to obtain an electronic device having a novel configuration in which rattling of the first housing mounted on the mounting portion is easily suppressed.

  The shape of the first housing 11 is a substantially rectangular parallelepiped that is flat in the vertical direction. The first housing 11 has, for example, a plurality of walls such as a lower wall 11c, an upper wall 11d, a front wall 11e, a rear wall 11f, a left wall 11g, and a right wall 11h.

  The lower wall 11c includes a lower surface 11b, and the upper wall 11d includes an upper surface 11a. Both the lower wall 11c and the upper wall 11d extend along a direction (XY plane) orthogonal to the Z direction, and are provided in parallel with each other at intervals in the Z direction. The lower wall 11c is provided with a plurality of support members 43 (FIGS. 2 and 3) for supporting the first housing 11 in a state separated from the flat surface 100a of the mounting portion 100. The support member 43 is also called a leg, a rubber leg, or the like.

  Both the front wall 11e and the rear wall 11f extend in a direction (YZ plane) orthogonal to the X direction, and are provided in parallel with each other at intervals in the X direction. The front wall 11e and the rear wall 11f constitute a front end 11i and a rear end 11j of the first housing 11, respectively. The front end 11i is separated from the rotation center axis C.

The upper cover 14 includes at least the upper wall 11d. The lower cover 13 is an example of a first member, and the upper cover 14 is an example of a second member.

  FIG. 4 is an exemplary bottom view of the electronic device 1 according to the embodiment. As shown in FIG. 4, the lower cover 13 is connected to the upper cover 14 by screws 42 and retaining members 41. The retaining member 41 is also called a connecting member or a connecting member.

  Next, the support of the lower cover 13 by the retaining member 41 will be described with reference to FIGS. FIG. 5 is an XZ cross-sectional view of a part of the electronic device 1 according to the embodiment, and is a diagram illustrating a state where the display unit 3 is located at the closed position. FIG. 6 is an enlarged view of the VI section in FIG.

  As shown in FIG. 5, on the inner surface 14 a of the upper cover 14, there is provided a tubular portion 15 connected to the retaining member 41. The cylindrical portion 15 protrudes in a first direction D1 from the upper cover 14 toward the lower cover 13. The cylindrical portion 15 is formed, for example, in a cylindrical shape, and a female screw 15b is formed in an inner peripheral portion. The cylindrical portion 15 is also called a boss.

  Further, as shown in FIG. 5, a through hole 11ba is provided in the lower wall 11c of the lower cover 13. The cylindrical portion 15 is inserted into the through hole 11ba. The diameter of the through hole 11ba is larger than the outer diameter of the cylindrical portion 15. That is, as shown in FIG. 6, a gap is formed between the outer peripheral surface 11bb (FIG. 6) of the lower wall 11c where the through hole 11ba is formed and the outer peripheral surface 15c of the cylindrical portion 15. The lower wall 11c is an example of a wall provided with the through-hole 11ba.

  As shown in FIG. 5, the retaining member 41 is configured as a male screw member, and has a shaft portion 41a and a head portion 41b. The shaft portion 41a is placed in the cylindrical portion 15. On the outer peripheral portion of the shaft portion 41a, a male screw 41c coupled to the female screw 15b of the cylindrical portion 15 is provided. The head 41b is connected to an end of the shaft 41a in the first direction D1. The head 41b is formed in a disk shape. The head 41b is overlapped with the distal end surface 15a of the tubular portion 15. The peripheral portion of the through hole 11ab in the lower wall 11c is inserted between the head 41b and the end surface in the first direction D1 of the cylindrical portion 15, that is, the distal end surface 15a, and the head 41b is connected to the lower wall 11c. The contact restricts the movement of the lower wall 11c in the first direction D1. That is, the head 41b prevents the lower wall 11c from coming off from the cylindrical portion 15.

  Further, a rib 16 adjacent to the cylindrical portion 15 is provided on the inner surface 14 a of the upper cover 14. A broken line L1 in FIG. 5 indicates a boundary portion between the rib 16 and the cylindrical portion 15. The rib 16 protrudes from the inner surface 14a in the first direction D1. The height of the rib 16 in the first direction D1 is lower than the height of the cylindrical portion 15 in the first direction D1. That is, as shown in FIG. 6, the end face of the rib 16 in the first direction D1, that is, the tip end face 16 a is located in the direction opposite to the first direction D1 with respect to the tip end face 15 a of the cylindrical portion 15. The distal end surface 16a of the rib 16 is located at a distance from the head 41b in a direction opposite to the first direction D1 with respect to the head 41b. The distal end face 16a of the rib 16 restricts the movement of the lower wall 11c in the opposite direction to the first direction D1 by contacting the lower wall 11c. As shown in FIG. 6, the height of the cylindrical portion 15 protruding from the rib 16 is greater than the thickness of the lower wall 11c. Therefore, the distance in the first direction D1 between the distal end surface 16a of the rib 16, the surface 41d of the head portion 41b in the opposite direction to the first direction D1, and the distal end surface 15a of the cylindrical portion 15 is smaller than the thickness of the lower wall 11c. Is also big. Therefore, the lower wall 11c is movable along the first direction D1 with respect to the upper cover 14 between the distal end surface 16a of the rib 16 and the surface 41d of the head 41b.

  As described above, at least a portion of the lower cover 13 is movable within a predetermined range with respect to the upper cover 14 in a direction along the first direction D1 and a direction orthogonal to the first direction.

  Next, the support member 43 will be described in detail. As shown in FIG. 4, the support member 43 is provided for each of the corners 11na to 11nd of the first housing 11 and protrudes from the lower surface 11b. Hereinafter, when the plurality of support members 43 are separately described, the plurality of support members 43 are also referred to as support members 43A to 43D. The support members 43A to 43D correspond to the corners 11na to 11nd, respectively.

  The support members 43A and 43D are moved toward the front end 11i of the front end 11i and the rear end 11j of the first housing 11, and are spaced from each other in the axial direction of the rotation center axis C. The support members 43B and 43C are moved toward the rear end 11j of the front end 11i and the rear end 11j of the first housing 11, and are spaced from each other in the axial direction of the rotation center axis C.

  Each of the support members 43A to 43D is made of an elastomer, and has elasticity. The shape of the support member 43A is different from the shapes of the other support members 43B to 43D. The shapes of the other support members 43B to 43D are the same as each other.

  FIG. 7 is an XZ sectional view of a part of the base unit 2 in the electronic device 1 of the embodiment. The shape of the support members 43B to 43D and the shape of the support member 43A will be described with reference to FIG. As for the shapes of the support members 43B to 43D, the support member 43B will be described as a representative thereof. The support member 43A indicated by a dashed line in FIG. 7 is in a free state, and the support member 43A indicated by a solid line in FIG. 7 is placed on the plane 100a and elastically deformed.

  As shown in FIG. 7, the support member 43B has a main body 43a, a hook 43b, and a connection 43c. The main body 43a is located outside the lower wall 11c. The main body 43a is formed in a substantially disk shape. The main body 43a has an upper surface 43d and a lower surface 43e opposite to the upper surface 43d. The upper surface 43d is formed in a flat circular shape, and is attached to the lower surface 11b of the lower wall 11c with an adhesive or the like. The upper surface 43d is formed as a circular convex surface in the first direction D1 toward the center of the upper surface 43d. The hook 43b is overlapped on the inner surface of the lower wall 11c and is hooked on the inner surface. The connection part 43c penetrates the lower wall 11c and connects the main body part 43a and the hook part 43b.

  The support member 43A has a main body 43a, a hook 43b, and a connection 43c, like the support member 43B. However, a concave portion 44 is provided in the main body 43a of the support member 43A. The concave portion 44 is provided on the upper surface 43d. The recess 44 is recessed downward and opened upward. The recess 44 communicates with a vent 45 provided in the lower wall 11c. The ventilation hole 45 is a through-hole penetrating the lower wall 11c in the thickness direction of the lower wall 11c. The concave portion 44 is an example of a space. The vent 45 is also called an opening. When a ventilation hole for bleeding air is formed in the main body portion 43a of the support member 43A, the air in the concave portion 44 is hardly released because the flat surface 100a of the desk or the like is closed, and the support member 43A is not easily deformed. On the other hand, in the present embodiment, since the air in the concave portion 44 passes through the vent 45, the support member 43A can be easily elastically deformed.

  The height h of the support member 43A from the lower surface 11b is higher than the other support members 43B to 43D. The height h at this time is a height when the support member 43 is in a free state. Further, the support member 43A is more easily elastically deformed than the other support members 43B to 43D. In other words, the support member 43A has a higher elastic deformation rate (elastic modulus) than the other support members 43B to 43D. Specifically, the support member 43A is easily elastically deformed such that the height in the direction along the first direction D1 is smaller than the other support members 43B to 43D.

  The attachment position of the support member 43A can be determined according to, for example, the rigidity of the first housing 11 and the base portion 2, the position of the center of gravity of the base portion 2, and the like. For example, when the base part 2 is different between the left and right, the support member 43A may be provided on the side having the higher rigidity. Note that the left and right rigidity of the base portion 2 is represented by, for example, the amount of deflection of the left and right ends of the front end 11i when the rear end 11j is a fixed end and the left and right ends of the front end 11i are pressed down. be able to. When the position of the center of gravity of the base portion 2 is shifted from the center of the shape of the base portion 2, the support member 43A may be provided on the opposite side of the center of the shape of the base portion 2 from the position of the center of gravity of the base portion 2. .

  Next, the second housing 21 will be described in detail. As shown in FIGS. 1 to 3, the shape of the second housing 21 is a flat, substantially rectangular parallelepiped. The second housing 21 has a plurality of walls such as a front wall 21c, a rear wall 21d, a lower wall 21e, an upper wall 21f, a left wall 21g, and a right wall 21h.

  The front wall 21c includes a front surface 21a, and the rear wall 21d includes a rear surface 21b.

  The lower wall 21e and the upper wall 21f form a lower end 21i and an upper end 21j of the second housing 21, respectively. The upper end 21j is separated from the rotation center axis C. The lower end 21i is provided on the rotation center axis C side with respect to the upper end 21j.

  The lower end 21i is offset from the rotation center axis C such that the lower end 21i contacts the plane 100a in a state where the second housing 21 is located at the deployed position (FIG. 2). At this time, the support members 43B and 43C are separated from the plane 100a. Therefore, when the first housing 11 is placed on the flat surface 100a in a state where the second housing 21 is located at the development position (FIG. 2), the two support members 43A and 43D and the lower end 21i are connected. Three places contact the plane 100a. That is, the electronic device 1 is supported at three points. The upper end 21j is an example of a third end, and the lower end 21i is an example of a fourth end.

  The left wall 21g and the right wall 21h constitute a left end 21k and a right end 21m of the second housing 21, respectively.

  The second housing 21 is configured by a combination of a plurality of members including a front cover 23 and a rear cover 24. The front cover 23 includes a part of the front wall 21c. The rear cover 24 includes at least a rear wall 21d.

  Next, the shape of the lower end 21i of the second housing 21 will be described in detail with reference to FIG. FIG. 8 is an exemplary rear view of a part of the lower end 21i of the display unit 3 in the electronic device 1 of the embodiment. As shown in FIG. 8, the lower end portion 21i has a convex portion 21p projecting in a second direction D2 which is a direction from the upper end portion 21j toward the lower end portion 21i. In FIG. 8, the height of the protrusion 21p is exaggerated for the sake of understanding. The height of the projection 21p gradually increases toward the center of the lower end 21i in the axial direction of the rotation center axis C. The tip surface 21q of the convex portion 21p is a curved surface. Specifically, the distal end surface 21q is an arcuate curved surface. Further, at least a part of the lower end portion 21i and the convex portion 21p is constituted by an elastic member 51. The elastic member 51 is, for example, an elastomer.

  When the first housing 11 is placed on the flat surface 100a in a state where the second housing 21 is located at the deployed position, the portion of the lower end 21i that comes into contact is the tip end surface 21q of the projection 21p. That is, when the first housing 11 is placed on the flat surface 100a in a state where the second housing 21 is located at the unfolded position, three places of the two support members 43A and 43D and the protrusion 21p correspond to the flat surface 100a. Contact.

  As described above, in the present embodiment, the electronic device 1 includes the lower cover 13 (the first member) and the inner surface 14 a of the upper cover 14 (the second member 14) as an example. And a cylindrical portion 15 protruding in a first direction D1 from one (the upper cover 14 as an example) to the other (the lower cover 13 as an example). The other of the lower cover 13 and the upper cover 14 (the lower cover 13 as an example) has a lower wall 11c (wall) provided with a through hole 11ba in which the cylindrical portion 15 is inserted and whose diameter is larger than the outer diameter of the cylindrical portion 15. are doing. The retaining member 41 has a shaft portion 41a inserted into the cylindrical portion 15 and a head that is connected to the shaft portion 41a and overlaps the distal end surface 15a of the cylindrical portion 15 to prevent the lower wall 11c from coming off from the cylindrical portion 15. 41b.

  According to such a configuration, for example, since the lower wall 11c can be moved in the orthogonal direction orthogonal to the first direction D1, the lower cover 13 is moved when the first housing 11 is mounted on the mounting portion 100. Even if it is distorted by an external force, at least a part of the lower cover 13 can move in the orthogonal direction orthogonal to the first direction D1 with respect to the upper cover 14 in accordance with the distortion. Therefore, the backlash of the first housing 11 is easily suppressed. When the external force is released, the above-mentioned distortion is eliminated, and the lower cover 13 and the upper cover 14 return to a predetermined positional relationship.

  In the present embodiment, for example, the lower wall 11c is provided movably along the first direction D1 with respect to the lower cover 13.

  According to such a configuration, for example, the first housing 11 is mounted on the mounting portion 100 by the lower wall 11c being provided movably with respect to the lower cover 13 along the first direction D1. In this case, even if the lower cover 13 is distorted by an external force, the lower cover 13 may move with respect to the upper cover 14 in the orthogonal direction orthogonal to the first direction D1 or in the first direction D1 in accordance with the distortion. it can. Therefore, rattling of the first housing 11 is more easily suppressed.

  In the present embodiment, for example, one of the lower cover 13 and the upper cover 14 (for example, the upper cover 14) is spaced from the head 41b in the direction opposite to the first direction D1 with respect to the head 41b. And a distal end surface 16a (restriction portion) that restricts movement of the lower wall 11c in the opposite direction to the first direction D1 by contacting the lower wall 11c.

  According to such a configuration, for example, the distal end surface 16a limits the movement of the lower wall 11c in the direction opposite to the first direction D1, so that the movement amount of the lower wall 11c can be limited.

  In the present embodiment, for example, the first housing 11 is moved toward the front end 11i of the front end 11i (first end) and the rear end 11j (second end), and the rotation center axis. Two support members 43A and 43D are provided at intervals in the axial direction of C and protrude from the lower surface 11b (first surface). The lower end 21i (fourth end) of the second housing 21 has a protrusion 21p protruding in the second direction D2 (direction) from the upper end 21j (third end) toward the lower end 21i. . The second housing 21 has a closed position (first position) where the upper surface 11a (second surface) and the front surface 21a (third surface) face each other, and a developed position (second position) where the upper surface 11a and the front surface 21a do not face each other. It is rotatable between. When the first housing 11 is placed on the flat surface 100a in a state where the second housing 21 is located at the development position, three places of the two support members 43A and 43D and the protrusion 21p come into contact with the flat surface 100a. .

  According to such a configuration, for example, since the convex portion 21p is provided at the lower end portion 21i, even if the first housing 11 or the second housing 21 has an assembly variation or a shape variation, the first housing 11 or the second housing 21 has a variation. When the body 11 is placed on the plane 100a, the projection 21p contacts the plane 100a at the lower end 21i. Therefore, when the first housing 11 is placed on the flat surface 100a in a state where the second housing 21 is located at the deployed position, rattling of the first housing 11 is easily suppressed.

  In the present embodiment, for example, the height of the protrusion 21p gradually increases toward the center of the lower end 21i in the axial direction of the rotation center axis C.

  According to such a configuration, for example, when the first housing 11 is placed on the plane 100a, the contact between the protrusion 21p and the plane 100a is close to a point contact. Therefore, rattling of the first housing 11 is more easily suppressed.

  In the electronic device 1, for example, the distal end surface 15a of the projection 21p is a curved surface.

  According to such a configuration, for example, since the distal end surface 15a of the projection 21p is a curved surface, the flat surface 100a that contacts the projection 21p is not easily damaged.

  In the electronic device 1, for example, the first housing 11 is provided with a plurality of support members 43A to 43D each having elasticity and projecting from the lower surface 11b. One support member 43A among the plurality of support members 43A to 43D has a higher height h from the lower surface 11b and is more easily elastically deformed than the other support members 43B to 43D.

  According to such a configuration, for example, even when there is a variation in the shape of the first housing 11 or a deviation between the shape center and the position of the center of gravity, when the first housing 11 is placed on the flat surface 100a, When the support member 43A is elastically deformed, the plurality of support members 43A to 43D can contact the plane 100a. Therefore, the backlash of the first housing 11 is easily suppressed.

  In the above embodiment, the tubular portion 15 is provided on the upper cover 14), and the through-hole 11ba is provided on the lower wall 11c of the lower cover 13, but the present invention is not limited to this. For example, the cylindrical portion 15 may be provided on the lower cover 13, and the through-hole 11 ba may be provided on the upper wall 11 d of the upper cover 14.

  Further, in the above embodiment, the example in which the vent 45 is provided in the first housing 11 has been described, but the present invention is not limited to this. For example, the vent 45 may be provided in the support member 43A, or may be provided in both the first housing 11 and the support member 43A. In the case where the vent 45 is provided in the support member 43A, by providing the vent 45 at a position where the vent 45 is not blocked by the flat surface 100a, air can be satisfactorily discharged from the vent 45.

  Further, in the above-described embodiment, an example is described in which the distal end surface 21q of the convex portion 21p is an arcuate curved surface, but the present invention is not limited to this. For example, the distal end surface 21q of the convex portion 21p may be a curved surface having an arc shape or a triangular shape. In addition, one or more concave portions may be partially formed in the convex portion 21p. Further, the height of the convex portion 21p may gradually increase toward the center of the lower end portion 21i.
