The guide groove 161 has a lock portion 162 at one end and an opening 163 at the other end. Lock portion 162 is arranged above opening 163. When the shaft 13b of the swing arm 13 is positioned on the lock portion 162, the rotation of the swing arm 13 is restricted. The opening 163 is open rearward. The shaft 13b of the swing arm 13 enters and exits the guide groove 161 from the opening 163. When the shaft 13b of the swing arm 13 retreats from the guide groove 161 and comes off, the rotation restriction of the swing arm 13 is released.

  The release arm 17 moves the lock slider 16 to a position that restricts the rotation of the lift arm 12 and the rotation of the swing arm 13, and a position that releases the rotation restriction of the lift arm 12 and the rotation restriction of the swing arm 13.

  The release arm 17 has a guide groove 171 at the other end around the shaft 21a. The guide groove 171 is engaged with the shaft 16a of the lock slider 16 so as to be able to advance and retreat. The guide groove 171 is open forward. The guide groove 171 is formed in a shape along the track of the shaft 16a. The guide groove 171 has a holding portion 172 and a cam portion 173. The holding portion 172 and the cam portion 173 are continuous. The holding portion 172 is formed in a U-shape. The cam portion 173 is arranged facing the opening. The cam portion 173 is formed in a cam shape for guiding the shaft 16a.

  The release arm 17 configured as described above is rotated by the lift guide arm 19. When the lift guide arm 19 rotates clockwise and the release arm 17 rotates counterclockwise in a state where the shaft 16a of the lock slider 16 is engaged with the guide groove 171, the lock slider 16 moves upward.

  When the lift guide arm 19 rotates counterclockwise and the release arm 17 rotates clockwise while the shaft 16a of the lock slider 16 is engaged with the guide groove 171, the lock slider 16 moves downward.

  The down arm 18 is rotatably arranged on the slider 11 via the shaft 11a. The down arm 18 is rotated by the rotation of the lift guide arm 19 by the second drive unit 95. The down arm 18 is connected to the rear arm 14.

The control unit 90 controls the first drive unit 91 and the second drive unit 95 based on the program stored in the memory. The control unit 90 can simultaneously control the first drive unit 91 and the second drive unit 95. The control unit 90 acquires a detection result from the first sensor 94S. The control unit 90 acquires a detection result from the second sensor 98S.

  The control unit 90 outputs a control signal for controlling driving and stopping of the motor 92. For example, as shown by a broken line in FIG. 9, the control unit 90 transmits a control signal for driving the motor 92 so that the slider 11 moves by a corresponding moving amount of the slider 11 in accordance with the opening angle of the panel frame 32. Output. The control unit 90 can calculate the amount of movement of the slider 11 based on the amount of movement of the rack 94, which is the detection result of the first sensor 94S.

  The control unit 90 outputs a control signal for controlling driving and stopping of the motor 96. For example, as shown by a solid line in FIG. 9, the control unit 90 drives the motor 96 so that the lift guide arm 19 moves by a corresponding movement amount of the lift guide arm 19 according to the opening angle of the panel frame 32. Output a control signal. The control unit 90 can calculate the amount of rotation of the lift guide arm 19 based on the amount of movement of the lift slider, which is a detection result of the second sensor 98S.

  For example, when the panel frame 32 in the upright state is disposed to be recessed with respect to the cluster panel, the center console, and the instrument panel, the control unit 90 may open the panel frame 32 before opening the panel frame 32, as shown by a dashed line in FIG. Alternatively, a control signal may be output so as to move the slider 11 a predetermined distance forward. During the reverse tilt operation or the tilt operation, the panel frame 32 and the cluster panel, the center console, and the instrument panel can be operated without interference.

  Next, the reverse tilt operation and the tilt operation of the electronic device 1 configured as described above will be described.

  First, the upright state of the display unit 3 will be described with reference to FIGS. The panel frame 32 is upright. The panel frame 32 is closed with respect to the sub panel 22. In other words, the panel frame 32 is housed in the opening of the sub panel 22. The lift arm 12 is urged by a torsion coil spring to rotate clockwise around the shaft 12a. The lift arm 12 comes into contact with the stopper 33 and the clockwise rotation is regulated. The swing arm 13 is urged by a torsion coil spring to rotate clockwise about the shaft 32b. The swing arm 13 comes into contact with a stopper (not shown) arranged on the panel frame 32 to restrict clockwise rotation. Since the shaft 16a of the lock slider 16 is located in the lock groove 121 of the lift arm 12, the rotation of the lift arm 12 is restricted. Since the shaft 13b of the swing arm 13 is located at the lock portion 162 of the guide groove 161 of the lock slider 16, the rotation of the swing arm 13 is restricted. Since the shaft 16a of the lock slider 16 is located in the guide groove 171 of the release arm 17, the lock slider 16 is positioned and its upward movement is restricted.

  The tilt operation of the display unit 3 will be described with reference to FIGS. FIG. 11 is a side view illustrating a tilt operation of the display unit according to the embodiment. FIG. 12 is a side view illustrating a tilt operation of the display unit according to the embodiment. FIG. 13 is a side view illustrating a tilt operation of the display unit according to the embodiment. FIG. 14 is a side view illustrating a tilt operation of the display unit according to the embodiment. FIG. 15 is a side view illustrating a tilt operation of the display unit according to the embodiment. The tilt operation is performed from the erect state of the display unit 3. When the tilt operation is started, the slider 11 is driven by the first drive unit 91 and moves forward with respect to the sub panel 22.

  The state shown in FIG. 11 is a state in which the display unit 3 is performing a tilt operation. As shown in FIGS. 3 to 5, the tilt operation starts from a state in which the rotation of the lift arm 12 and the swing arm 13 is restricted. In the tilt operation, the lift arm 12, the swing arm 13, the rear arm 14, and the lock slider 16 move integrally with the panel frame 32. In other words, in the tilt operation, the lift arm 12, the swing arm 13, the rear arm 14, and the lock slider 16 move without changing the attitude with respect to the panel frame 32. In the state shown in FIG. 11, the slider 11 has advanced with respect to the sub-panel 22 from the state shown in FIGS. In conjunction with the advance of the slider 11, the shaft 13a moves downward along the guide groove 23 of the sub panel 22, and the lower end of the swing arm 13 to which the shaft 32b is connected moves forward. As a result, the upper portion of the panel frame 32 moves downward, the lower portion of the panel frame 32 moves forward, and the panel frame 32 tilts rearward.

  In the state shown in FIG. 12, the slider 11 is further advanced with respect to the sub-panel 22 from the state shown in FIG. The shaft 16a is separated from the guide groove 171 and is located forward of the guide groove 171. In conjunction with the advance of the slider 11, the upper portion of the panel frame 32 moves further downward, the lower portion of the panel frame 32 moves further forward, and the panel frame 32 further tilts rearward.

  In the state shown in FIG. 13, the slider 11 is further advanced with respect to the sub-panel 22 from the state shown in FIG. In conjunction with the advance of the slider 11, the upper portion of the panel frame 32 moves further downward, the lower portion of the panel frame 32 moves further forward, and the panel frame 32 further tilts rearward.

  In the state shown in FIG. 14, the slider 11 is further advanced with respect to the sub-panel 22 from the state shown in FIG. In conjunction with the advance of the slider 11, the upper portion of the panel frame 32 moves further downward, the lower portion of the panel frame 32 moves further forward, and the panel frame 32 further tilts rearward.

  In the state shown in FIG. 15, the slider 11 is further advanced with respect to the sub-panel 22 from the state shown in FIG. In conjunction with the advance of the slider 11, the upper portion of the panel frame 32 moves further downward, the lower portion of the panel frame 32 moves further forward, and the panel frame 32 further tilts rearward.

  Thus, the panel frame 32 is in a tilted state with the display surface 31 facing upward. The panel frame 32 opens with respect to the sub-panel 22, the tilt operation is completed, and the sub-panel 22 is fully opened. The height of the opening at this time is H. The greater the opening height H, the easier the operation on the media slot.

  In such a tilting operation, the display unit 3 tilts backward by performing a forward movement of the slider 11 with respect to the sub-panel 22, thereby performing a tilting operation. For example, the panel frame 32 is inclined backward by about 80 °.

  A case where the display unit 3 is returned from the tilt state to the upright state will be described. By moving the slider 11 backward with respect to the sub-panel 22, the display unit 3 returns to the upright state. More specifically, in conjunction with the retraction of the slider 11, the lower part of the panel frame 32 is pulled back backward, the upper part of the panel frame 32 moves upward along the guide groove 23 of the sub-panel 22, and the panel frame 32 closes. Return to the erect state. When returning to the erected state, the shaft 13b of the swing arm 13 remains at the lock portion 162 of the guide groove 161 of the lock slider 16, so that the state in which the rotation of the swing arm 13 is restricted is maintained. Thus, the swing arm 13 is rotated by the reaction force when the panel frame 32 is closed, and the swing arm 13 and the panel frame 32 are prevented from opening around the shaft 32b as a fulcrum. Thus, when returning the display unit 3 from the tilted state to the erect state, the loss of the driving force of the slider 11 can be suppressed. When returning to the upright state, the shaft 16a of the lock slider 16 enters the guide groove 171 of the release arm 17, and the upward movement of the lock slider 16 is restricted.

  The reverse tilt operation of the display unit 3 will be described with reference to FIGS. FIG. 16 is a side view illustrating an erect state of the display unit according to the embodiment. FIG. 17 is a side view illustrating the reverse tilt operation of the display unit according to the embodiment. FIG. 18 is a side view illustrating the reverse tilt operation of the display unit according to the embodiment. FIG. 19 is a side view illustrating the reverse tilt operation of the display unit according to the embodiment. FIG. 20 is a side view illustrating the reverse tilt operation of the display unit according to the embodiment. FIG. 21 is a side view illustrating the reverse tilt operation of the display unit according to the embodiment. FIG. 22 is a side view illustrating the reverse tilt operation of the display unit according to the embodiment. The reverse tilt operation is started from the erect state of the display unit 3. When the reverse tilt operation is started, the slider 11 is driven by the first drive unit 91 and moves backward with respect to the sub panel 22. The lift guide arm 19 is driven by the second drive unit 95 and rotates clockwise.

  The state shown in FIG. 16 is a state in which the rotation regulation of the lift arm 12 and the swing arm 13 has been released from the state shown in FIGS. From the state shown in FIG. 3 to FIG. 5, the release arm 17 is rotating counterclockwise about the shaft 21a. The guide groove 171 of the release arm 17 pushes up the shaft 16a, and the lock slider 16 moves upward. When the shaft 16a of the lock slider 16 is separated from the lock groove 121 of the lift arm 12, the rotation restriction of the lift arm 12 is released and the movement restriction of the lock slider 16 is released. The shaft 13b of the swing arm 13 is disengaged from the lock portion 162 of the guide groove 161 of the lock slider 16, and the rotation of the swing arm 13 is released.

  In the state shown in FIG. 17, the slider 11 is retracted with respect to the sub panel 22 from the state shown in FIG. Since the protrusion 12b is in contact with the lift stopper 15, the lift arm 12 is restricted from moving backward. Accordingly, the lift arm 12 rotates counterclockwise about the shaft 12a in conjunction with the retraction of the slider 11. The shaft 13b of the swing arm 13 is separated from the guide groove 161 of the lock slider 16. The attitude of the swing arm 13 with respect to the panel frame 32 changes in conjunction with the retraction of the slider 11 and the forward inclination of the panel frame 32. The shaft 16 a of the lock slider 16 is located on the cam portion 173 of the release arm 17. The lock slider 16 is urged downward by a tension coil spring (not shown). As a result, the lock slider 16 moves downward while being guided by the cam portion 173 in conjunction with the forward inclination of the panel frame 32. In conjunction with the retraction of the slider 11 and the rotation of the lift arm 12, the upper portion of the panel frame 32 moves forward, and the panel frame 32 rotates around the shaft 32a and leans forward. The rotation of the lift arm 12 causes the lower shaft 32a of the panel frame 32 to move upward.

  In the state shown in FIGS. 18 and 19, the slider 11 is further retracted with respect to the sub-panel 22 from the state shown in FIG. In conjunction with the retraction of the slider 11, the lift arm 12 further rotates counterclockwise about the shaft 12a. In conjunction with the retraction of the slider 11, the swing arm 13 further rotates counterclockwise. The attitude of the swing arm 13 with respect to the panel frame 32 further changes in conjunction with the retraction of the slider 11 and the forward tilt of the panel frame 32. The lock slider 16 moves further downward while being guided by the cam portion 173. The lock slider 16 is in contact with the stopper 33. The downward movement of the lock slider 16 is restricted. In conjunction with the retraction of the slider 11 and the rotation of the lift arm 12, the upper portion of the panel frame 32 moves further forward, and the panel frame 32 rotates about the shaft 32a and further leans forward. By the rotation of the lift arm 12, the lower shaft 32a of the panel frame 32 moves further upward.

  When the panel frame 32 performs the reverse tilt operation to the predetermined angle in this manner, the slider 11 stops retreating. Further, the lift guide arm 19 is rotated clockwise by the second drive unit 95. For example, the predetermined angle is 10 °. In the present embodiment, it is assumed that the panel frame 32 is at a predetermined angle between the states shown in FIGS. 18 and 19 and the states shown in FIGS.

  In the state shown in FIGS. 20 and 21, the slider 11 is further retracted with respect to the sub-panel 22 from the state shown in FIGS. The lift guide arm 19 is driven by the second drive unit 95 and rotates clockwise about the shaft 11a. In conjunction with the retraction of the slider 11, the lift arm 12 rotates counterclockwise about the shaft 12a. In conjunction with the rotation of the lift guide arm 19, the down arm 18 rotates clockwise about the shaft 11a. In conjunction with the rotation of the down arm 18, the lower part of the rear arm 14 moves downward. The shaft 13 a of the swing arm 13 connected to the rear arm 14 moves downward along the guide groove 23 of the sub panel 22. When the shaft 13a moves downward, the swing arm 13 moves forward while the end on the side where the shaft 32b is connected is pushed down. In conjunction with the operation of the swing arm 13 and the rear arm 14 in conjunction with the rotation of the down arm 18, the panel frame 32 rotates about a shaft 32a, the upper part moves forward, and the lower shaft 32a moves downward. Go to and lean further forward.

  In the state shown in FIG. 22, the lift guide arm 19 is further rotated clockwise about the shaft 11a from the state shown in FIGS. The down arm 18 further rotates clockwise about the shaft 11a. In conjunction with the rotation of the down arm 18, the lower part of the rear arm 14 moves further downward. The shaft 13 a of the swing arm 13 moves further downward along the guide groove 23 of the sub panel 22. When the shaft 13a moves further downward, the swing arm 13 moves forward while the end on the side where the shaft 32b is connected is further pushed down. In conjunction with the operation of the swing arm 13 and the rear arm 14 in conjunction with the rotation of the down arm 18, the panel frame 32 further rotates about the axis 32a, the upper part moves further forward, and the lower axis 32a Moves further downward and leans forward further.

  Thus, the display unit 3 is in a reverse tilt state in which the display surface 31 faces downward. For example, the panel frame 32 is inclined forward by about 20 °.

  In such a reverse tilt operation, when the slider 11 retreats from the erect state with respect to the sub-panel 22, the protrusion 12b comes into contact with the lift stopper 15, so that the rearward movement of the lift arm 12 is restricted. In conjunction with the retraction of the slider 11, the lift arm 12 rotates counterclockwise about the shaft 12a. When the lift arm 12 rotates counterclockwise, the shaft 32a moves upward, so that the lower part of the panel frame 32 moves upward. The panel frame 32 rotates about the shaft 32a and performs a reverse tilt operation while lifting the lower part. When the panel frame 32 performs a reverse tilt operation to a predetermined angle, the lift guide arm 19 is rotated clockwise by the second drive unit 95. The down arm 18 rotates clockwise in conjunction with the lift guide arm 19. Through the swing arm 13 and the rear arm 14 that operate in conjunction with the rotation of the down arm 18, the panel frame 32 rotates about the shaft 32a and performs a reverse tilt operation while the lower part is pushed down.

  As described above, in the reverse tilt operation, the lower part of the panel frame 32 moves upward until the panel frame 32 reaches the predetermined angle from the erect state, and then moves downward after reaching the predetermined angle. Thereby, the expansion of the gap between the lower portion of the panel frame 32 and the lower surface of the sub panel 22 is reduced. The downward movement of the lower part of the panel frame 32 is equal to or less than the upward movement. The amount of upward movement of the lower portion of the panel frame 32 depends on the size of the panel frame 32 and the like, but is preferably 2 mm or less.

  A case where the display unit 3 is returned from the reverse tilt state to the erect state will be described. First, the lift guide arm 19 is rotated clockwise to return the panel frame 32 to a predetermined angle, and then the slider 11 is advanced with respect to the sub-panel 22, whereby the display unit 3 returns to the upright state. More specifically, first, the lift guide arm 19 is rotated counterclockwise about the shaft 11a by the second drive unit 95, and the down arm 18 is rotated counterclockwise about the shaft 11a. As a result, the panel frame 32 is closed to a predetermined angle via the swing arm 13 and the rear arm 14. Then, after the panel frame 32 is closed to a predetermined angle, the slider 11 is advanced with respect to the sub-panel 22, and the lift arm 12 is rotated clockwise about the shaft 12a. As a result, the panel frame 32 returns to the upright posture. At this time, the shaft 16a is located on the holding part 172. Further, from this state, the lift guide arm 19 is rotated counterclockwise by the second drive unit 95, whereby the release arm 17 is rotated, and the opening of the guide groove 171 is directed downward. Thus, the shaft 16a is pushed down, and the lock slider 16 moves downward. Thus, the panel frame 32 returns to the upright state. Further, the rotation of the lift arm 12 and the swing arm 13 is restricted by the lock slider 16.

  As described above, in the present embodiment, the reverse tilt operation is performed as follows. The lift arm 12 rotates counterclockwise about the shaft 12a in conjunction with the operation of the slider 11 retreating with respect to the sub panel 22 from the upright state. The panel frame 32 rotates clockwise about the axis 32a. By the rotation of the lift arm 12, the lower part of the panel frame 32 moves upward. When the panel frame 32 is reversely tilted to a predetermined angle, the second drive unit 95 causes the lift guide arm 19 to rotate clockwise and the down arm 18 to rotate clockwise. The shaft 32b is pushed down via the swing arm 13 and the rear arm 14 which operate in conjunction with the rotation of the down arm 18. The panel frame 32 further performs a reverse tilt operation while the lower portion is pushed down. Thus, in the present embodiment, the display unit 3 can perform the reverse tilt operation.

  In this embodiment, the tilt operation is performed as follows. The shaft 13a moves downward along the guide groove 23 of the sub-panel 22 in conjunction with the operation of the slider 11 advancing with respect to the sub-panel 22 from the upright state, and the end of the swing arm 13 to which the shaft 32b is connected is moved. Move forward. In this way, the display unit 3 performs a tilt operation while tilting backward. In the present embodiment, the display unit 3 can perform a tilt operation.

  In the present embodiment, at the time of the reverse tilt operation, the lower part of the panel frame 32 moves upward from the erect state until the panel frame 32 reaches a predetermined angle, and moves downward after reaching the predetermined angle. According to the present embodiment, the gap between the lower portion of the panel frame 32 and the lower surface of the sub panel 22 can be reduced. According to the present embodiment, the internal structure of the electronic device 1 can be made invisible from the gap. Further, according to the present embodiment, it is possible to suppress the entry of dust and the insertion of foreign substances such as fingers in the gap. Further, according to the present embodiment, the display unit 3 can perform the reverse tilt operation without interfering with the center console, the instrument panel, and the like in the passenger compartment.

  In this embodiment, after the display unit 3 is reversely tilted by the rotation of the lift arm 12, the display unit 3 is further tilted by the rotation of the down arm 18. According to the present embodiment, the angle of the panel frame 32 due to the reverse tilt operation can be increased.

  In the above, the electronic device 1 according to the invention has been described, but may be implemented in various different forms other than the above-described embodiment.

  The arrangement of the drive unit 9 may be changed according to the configuration of the display panel drive mechanism 10.

FIG. 23 is a perspective view illustrating another example of the drive unit of the display unit according to the embodiment. FIG. 24 is a perspective view illustrating another example of the drive unit of the display unit according to the embodiment. More specifically, the arrangement positions of the arm drive gear 98A and the connection shaft 99A of the second drive unit 95A are different from those of the drive unit 9 shown in FIG.
