  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the contents below.

<1. First Embodiment>
<1-1. Outline of panel rotation mechanism>
FIG. 1 is an external perspective view showing an example of a device E including the panel rotation mechanism 1 of the first embodiment. The panel rotation mechanism 1 is arranged at the connection point between the main body E1 of the device E and the panel E2. The panel rotation mechanism 1 is a mechanism that rotates the panel E2 with respect to the main body E1.

  The device E is, for example, a display device mounted in a vehicle and used in the vehicle interior. The main body E1 is fixed to the ceiling surface in the vehicle compartment by a fixing member such as a screw. The panel E2 includes, for example, a liquid crystal display panel, and has a plate-like substantially rectangular parallelepiped shape. The panel E2 includes a screen E21 on one plane in the thickness direction.

  The panel rotation mechanism 1 includes a panel base 2. The panel base 2 is supported by the main body E1. The panel base 2 rotates around the first axis C1 extending in the normal direction to the surface (lower surface E1a) of the main body E1 with respect to the main body E1. The panel base 2 supports the panel E2. As a result, the panel E2 rotates about the first axis C1 with respect to the main body E1.

  The panel base 2 rotatably supports the panel E2 around a second axis C2 orthogonal to the first axis C1. As a result, the panel rotation mechanism 1 closes the panel E2 so as to cover the screen E21 and adjoins the lower surface E1a of the main body E1, and the expanded state in which the panel E2 is erected downward from the main body E1 to open the screen E21 in a visible manner. It can be opened and closed. Note that FIG. 1 shows a developed state of the panel E2.

<1-2. Panel rotation mechanism details>
FIG. 2 is a partial vertical sectional view of the panel rotation mechanism 1 as viewed from the front. The front surface of the panel rotation mechanism 1 is in the same direction as the front surface of the screen E21 of the panel E2 in the expanded state. The panel rotation mechanism 1 includes a spacer 31 and a protruding member 41 in addition to the panel base 2.

  The panel base 2 includes a base housing 21, a first support shaft 22, and a second support shaft 23. The base housing 21 is composed of a box-shaped body having a substantially rectangular parallelepiped shape having a hollow inside. A first support shaft 22 and a second support shaft 23 are connected to the base housing 21.

  The first support shaft 22 extends along the first axis C1. One end of the first support shaft 22 is connected to the base casing 21, and the other end is connected to the main body E1. As a result, the panel base 2 is supported by the main body E1 so as to be rotatable about the first axis C1 via the first support shaft 22.

  The second support shaft 23 extends along the second axis C2. One end side of the second support shaft 23 is connected to the base housing 21, and the other end side thereof is connected to the panel E2. As a result, the panel base 2 supports the panel E2 so as to be rotatable about the second axis C2 via the second support shaft 23.

  The spacer 31 is arranged in the main body E1. The spacer 31 is made of a hard material such as metal and has a substantially rectangular parallelepiped shape. The lower portion of the spacer 31 is exposed downward from the lower surface E1a of the main body E1. That is, the spacer 31 faces the panel base 2. The lower portion of the spacer 31 bulges downward from the lower surface E1a of the main body portion E1, that is, toward the panel base portion 2.

  The protruding member 41 is arranged on the panel base 2. The protruding member 41 is a rod-shaped or pin-shaped member. The panel base portion 2 further includes a hole portion 24 and a biasing member 25. The hole 24 is arranged in a region of the base casing 21 facing the main body E1, and penetrates the base casing 21. The projecting member 41 is inserted into the hole 24. The biasing member 25 is arranged inside the base housing 21. The biasing member 25 is formed of, for example, a leaf spring, and contacts the head portion 41 a of the protruding member 41 located inside the base housing 21.

  The biasing member 25 biases the projecting member 41 in a direction toward the spacer 31. As a result, the projecting member 41 projects from the base housing 21 toward the main body E1. The tip of the projecting member 41 on the projecting side faces the main body E1 including the spacer 31. Since the head portion 41a is larger than the hole portion 24, the protruding member 41 does not fall off from the panel base portion 2.

<1-3. Operation of panel rotation mechanism>
FIG. 3 is an external perspective view showing the device E with the panel E2 rotated. FIG. 4 is a partial vertical cross-sectional view of the panel rotation mechanism 1 when the panel base 2 is not at a predetermined rotation angle as viewed from the side. FIG. 5 is a partial vertical sectional view of the panel rotation mechanism 1 when the panel base 2 is at a predetermined rotation angle as seen from the side.

  3 and 4 show the panel rotation mechanism 1 in a state where the panel base 2 is not at a predetermined rotation angle. The state in which the panel base portion 2 is not at the predetermined rotation angle is a state in which the lateral direction X1 of the main body portion E1 and the longitudinal direction X2 of the panel E2 are not parallel, as shown in FIG.

  In this state of the rotation angle of the panel base 2, the projecting member 41 does not face the spacer 31 as shown in FIG. That is, the projecting member 41 is biased by the biasing member 25 in the direction of approaching the spacer 31, and the tip projects from the base housing 21, but does not contact the spacer 31. Further, the protruding member 41 is provided with a predetermined gap also on the lower surface E1a of the main body E1, and does not contact the lower surface E1a.

  1, 2 and 5 show the panel rotation mechanism 1 in a state in which the panel base 2 has a predetermined rotation angle. The state in which the panel base portion 2 has a predetermined rotation angle is a state in which the left-right lateral direction X1 of the main body portion E1 and the longitudinal direction X2 of the panel E2 are substantially parallel, as shown in FIG.

  In this state of the rotation angle of the panel base portion 2, the projecting member 41 faces the spacer 31 as shown in FIG. That is, the projecting member 41 is biased by the biasing member 25 in a direction of approaching the spacer 31, and the tip of the projecting member 41 projects from the base housing 21 and comes into contact with the spacer 31. At this time, since the lower portion of the spacer 31 bulges toward the panel base portion 2, the protruding member 41 is displaced downward against the urging force of the urging member 25. In this way, the projecting member 41 is biased in a direction approaching the spacer 31, and comes into contact with the spacer 31 at a predetermined rotation angle around the first axis C1 of the panel base 2.

  According to the above configuration, when the panel E2 is rotated to the predetermined rotation angle around the first axis C1, the protruding member 41 and the spacer 31 are brought into contact with each other, and the protruding member 41 can be biased toward the spacer 31. it can. Therefore, when the panel E2 is rotated up to a predetermined rotation angle around the first axis C1, it is possible to prevent the panel E2 from swinging toward and away from the main body E1. More specifically, it is possible to prevent the left and right ends of the panel E2 in FIG. 1 from swinging toward and away from the main body E1. That is, in the panel rotation mechanism 1, it is possible to suppress the swing of the panel E2.

  Further, it is possible to prevent the trace of friction with the spacer 31 from being attached to the panel base portion 2. Furthermore, it is possible to prevent the main body portion E1 from rubbing marks on portions other than the spacer 31. As a result, it is possible to suppress the deterioration of the appearance of the device E. Further, when the panel base 2 is not in the predetermined rotation angle, the projecting member 41 does not come into contact with either the main body E1 or the spacer 31. As a result, the rotation of the panel E2 around the first axis C1 becomes smooth.

  In addition, since the panel base 2 includes the hole 24 and the biasing member 25 having the above-described configuration, the projecting member 41 can be easily brought into contact with the spacer 31 and biased toward the spacer 31. That is, with a simple configuration, it is possible to suppress the swing of the panel E2 in the direction toward and away from the main body E1.

  The panel base 2 further includes a lubricating member 26. The lubricating member 26 is arranged in the hole 24. The lubricating member 26 is formed of a sleeve-shaped bush with a flange into which, for example, a rod-shaped or pin-shaped member is inserted. The lubricating member 26 is interposed between the wall surface of the hole 24 and the protruding member 41.

  According to this configuration, the projecting member 41 can be smoothly moved in the direction of approaching or separating from the spacer 31. Further, when the projecting member 41 rides on the lower portion of the spacer 31 (contacts the spacer 31 and displaces downward in FIG. 5), the load is applied along the rotation direction of the panel base portion 2 (the lateral direction in FIG. 5). Is added, it is possible to prevent the protruding member 41 from being twisted and tilted. As a result, it is possible to improve the action of suppressing the swing of the panel E2 in the direction of approaching and separating from the main body E1.

  The spacer 31 and the protruding member 41 are respectively arranged at the ends A1 and A2 of the panel rotation mechanism 1 shown in FIG. In other words, the spacer 31 and the protruding member 41 are arranged in pairs at positions symmetrical with respect to the first axis C1.

  According to this configuration, the load related to the swing of the panel E2 evenly acts on the spacer 31 and the protruding member 41 arranged at each of the ends A1 and A2 of the panel rotation mechanism 1. This makes it possible to enhance the effect of suppressing the swing of the panel E2 in the direction of approaching and separating from the main body E1.

  As shown in FIGS. 4 and 5, the spacer 31 includes a sloped portion 31a. The slope portion 31a is inclined along the moving direction of the projecting member 41 as the panel base 2 rotates. That is, the inclined surface portion 31a inclines downward along the left-right lateral direction in FIGS. 4 and 5 from the outer side to the inner side of the spacer 31. The inclined surface portions 31a are arranged at both ends of the spacer 31 in the moving direction of the projecting member 41 with the rotation of the panel base portion 2, and are formed in a tapered shape.

  According to this configuration, the protruding member 41 in contact with the spacer 31 can be smoothly moved along the inclined surface portion 31a. As a result, it is possible to improve the action of suppressing the swing of the panel E2 in the direction of approaching and separating from the main body E1. Further, if the tip shape of the protruding member 41 is also a shape with a small contact area with the spacer 31, the protruding member 41 in contact with the spacer 31 can be moved more smoothly.

<1-4. Modification of panel rotation mechanism>
FIG. 6 is a partial vertical cross-sectional view of the panel rotation mechanism 1 of the modified example when the panel base 2 is not at a predetermined rotation angle as viewed from the side. FIG. 7 is a partial vertical cross-sectional view of the panel rotation mechanism 1 of the modified example when the panel base 2 is at a predetermined rotation angle as seen from the side.

  The spacer 31 of the panel rotation mechanism 1 of the modified example includes a recess 31b. The recess 31 b is arranged on the surface of the spacer 31 facing the panel base 2. That is, in FIG. 6 and FIG. 7, the recess 31 b is arranged on the lower surface of the spacer 31. The recess 31b is recessed toward the inside of the spacer 31, that is, upward in FIGS. 6 and 7.

  As shown in FIG. 7, when the panel base 2 is at a predetermined rotation angle, the protruding member 41 contacts the lower surface of the spacer 31. When the protruding member 41 reaches the location of the recess 31b, the tip of the protruding member 41 is housed in the recess 31b.

  According to the above configuration, the protrusion member 41 can be positioned using the recess 31b. That is, in addition to the effect of suppressing the swing of the panel E2, it is possible to obtain the effect of maintaining the position of the panel E2 at a predetermined rotation angle around the first axis C1.

<2. Second Embodiment>
<2-1. Panel rotation mechanism details>
FIG. 8 is a partial vertical cross-sectional view of the panel rotation mechanism 1 of the second embodiment in which the panel base 2 is not at a predetermined rotation angle (1) when viewed from the side. Since the basic configuration of the second embodiment of the panel rotating mechanism 1 is the same as that of the first embodiment described above, the configuration different from that of the first embodiment will be described below and will be described as the first embodiment. Detailed description of common configurations will be omitted.

  The panel rotation mechanism 1 of the second embodiment includes a panel base 2, a spacer 32, a protruding member 42, and a magnet 5. The panel base 2 includes a base housing 21, a hole 24, a rotating shaft 27, and a holding member 28. The panel base 2 further includes a protruding member 42.

  The rotating shaft 27 is arranged inside the base housing 21. The rotating shaft 27 extends in a direction orthogonal to the first axis C1, that is, in the depth direction of the paper in FIG. The rotating shaft 27 rotatably supports the protruding member 42. As a result, the protruding member 42 rotates in a plane parallel to the first axis C1, that is, in a plane parallel to the paper surface in FIG.

  The holding member 28 is arranged on the outer peripheral portion of the rotating shaft 27. The holding member 28 is formed of, for example, a torsion coil spring, and the rotating shaft 27 is inserted into the coil portion. The holding member 28 has an elastic force that rotationally displaces the protruding member 42 in a direction in which the protruding member 42 is separated from the spacer 32. The holding member 28 holds the protruding member 42 in a posture separated from the spacer 32.

  The spacer 32 is arranged in the main body E1. The spacer 32 is composed of a plate-shaped spring member such as metal. The lower portion of the spacer 32 is exposed downward from the lower surface E1a of the main body E1. That is, the spacer 32 faces the panel base 2. An elastic force acts on the spacer 32 in a direction toward and away from the panel base 2. That is, the spacer 32 itself is a biasing member that biases the spacer 32 in the direction of approaching the protruding member 42.

  The spacer 32 includes a recess 32a. The recess 32 a is arranged on the surface of the spacer 32 facing the panel base 2. That is, in FIG. 8, the recess 32 a is arranged on the lower surface of the spacer 32. The recess 32a is recessed toward the inside of the main body E1, that is, upward in FIG.

  The protruding member 42 is arranged on the panel base 2. The protruding member 42 is rotatably supported via a rotating shaft 27 extending in a direction orthogonal to the first axis C1. The protruding member 42 rotates about an axis orthogonal to the first axis C1 in a plane parallel to the first axis C1. The protrusion member 42 has, for example, an elliptical surface of revolution, but the outer shape is not limited to the shape. For example, the protruding member 42 may have a rod shape extending in the direction orthogonal to the rotation shaft 27.

  The protruding member 42 includes a protrusion 42a. The protrusion 42a is arranged at one end in the major axis direction of the elliptical protrusion member 42. At least a part of the protruding member 42 including the protruding portion 42a and its periphery has magnetism.

  The magnet 5 is arranged in the main body E1. The magnet 5 is arranged inside the main body E1 adjacent to the spacer 32.

<2-2. Operation of panel rotation mechanism>
FIG. 9 is a partial vertical cross-sectional view of the panel rotation mechanism 1 of the second embodiment in which the panel base 2 is not at a predetermined rotation angle (2) when viewed from the side. FIG. 10 is a partial vertical cross-sectional view of the panel rotation mechanism 1 of the second embodiment in which the panel base 2 has a predetermined rotation angle (1) as seen from the side. FIG. 11 is a partial vertical cross-sectional view of the panel rotation mechanism 1 of the second embodiment in which the panel base 2 is in a predetermined rotation angle (2) when viewed from the side.

  8 and 9 show the panel rotation mechanism 1 in a state where the panel base 2 is not at a predetermined rotation angle. The state in which the panel base portion 2 is not at a predetermined rotation angle is a state in which the left-right lateral direction X1 of the main body portion E1 and the longitudinal direction X2 of the panel E2 are not parallel, as shown in FIG.

  When the panel base 2 is in the state of the rotation angle shown in FIG. 8, the protruding member 42 is sufficiently separated from the spacer 32. At this time, the protruding member 42 is held by the elastic force of the holding member 28 such that the major axis direction of the elliptical shape is substantially parallel to the lower surface E1a of the main body E1. Note that the protrusion member 42 does not rotate too much beyond the posture shown in FIG. 8 due to the action of a stopper (not shown).

  Then, when the panel base 2 approaches the spacer 32 to the rotation angle shown in FIG. 9, the protruding member 42 is attracted to the magnet 5 and rotates. The magnet 5 displaces the protruding member 42 in the direction of approaching the spacer 32 by the magnetic force. As a result, the peripheral portion of the protrusion 42 a of the protrusion member 42 approaches the spacer 32. The elastic force of the holding member 28 is weaker than the attractive force of the magnet 5 with respect to the protruding member 42.

  10 and 11 show the panel rotation mechanism 1 in a state in which the panel base 2 has a predetermined rotation angle. The state in which the panel base portion 2 has a predetermined rotation angle is a state in which the left-right lateral direction X1 of the main body portion E1 and the longitudinal direction X2 of the panel E2 are substantially parallel, as shown in FIG.

  When the panel base 2 approaches the spacer 32 to the rotation angle shown in FIG. 10, the protruding member 42 contacts the spacer 32. At this time, the protruding member 42 is rotationally displaced, so that a part thereof protrudes from the hole 24 to the outside at a predetermined rotation angle around the first axis of the panel base 2. Then, the protrusion 42 a of the protrusion member 42 is caught in the recess 32 a of the spacer 32.

  Further, when the panel base 2 is rotated to the rotation angle shown in FIG. 11, the protruding member 42 reaches substantially directly below the spacer 32. The projecting member 42 rotates and stops until the major axis direction of the elliptical shape is further parallel to the first axis C1 (see FIG. 8) until the angle α is reached. At this time, the distance from the rotation axis C3 of the rotation shaft 27 to the tip of the protrusion 42a is longer than the distance from the rotation axis C3 of the rotation shaft 27 to the contact point of the recess 32a with the protrusion 42a. As a result, the periphery of the contact portion of the spacer 32 with the protruding member 42 is pushed toward the inside of the main body portion E1, that is, upward in FIG. 11, and elastically deformed. That is, a reaction force due to the elastic force of the spacer 32 acts on the protruding member 42. In this way, the spacer 32 is biased by the elastic force in the direction in which the spacer 32 approaches the projecting member 42, and contacts the projecting member 42 at a predetermined rotation angle around the first axis C1 of the panel base 2.

  According to the above configuration, when the panel E2 is rotated to the predetermined rotation angle around the first axis C1, the spacer 32 and the protruding member 42 are brought into contact with each other and the spacer 32 can be biased toward the protruding member 42. it can. Therefore, when the panel E2 is rotated up to a predetermined rotation angle around the first axis C1, it is possible to prevent the panel E2 from swinging toward and away from the main body E1. That is, in the panel rotation mechanism 1, it is possible to suppress the swing of the panel E2.

  FIG. 12 is a partial vertical cross-sectional view showing an enlarged view of the protruding member 42 of FIG. When the long axis direction of the elliptical shape is rotated from the state parallel to the first axis C1 to the angle α, the spacer 32 is formed in the contact portion 42t of the protrusion member 42 with the spacer 32. The reaction force F1 due to the elastic force of is applied. The component force F2 of the reaction force F1 along the minor axis direction of the elliptical shape acts as a force that prevents the rotation of the protruding member 42 from returning to the original state (reverse rotation). As a result, in addition to the effect of suppressing the swing of the panel E2, the effect of maintaining the position of the panel E2 at a predetermined rotation angle around the first axis C1 can be enhanced.

  Further, the protruding member 42 is rotatably supported via the rotating shaft 27, and the rotational displacement thereof causes the protruding member 42 to protrude from the hole 24, so that the protruding member 42 can be easily brought into contact with the spacer 32. That is, with a simple configuration, it is possible to suppress the swing of the panel E2 in the direction toward and away from the main body E1.
