JP 2003-196966 A

  In the on-vehicle electronic device, when the gear rotates, a force that moves inward and outward of the case acts on the slider mechanism, but the dimension at the engaging portion between the gear and the slider mechanism It is unavoidable that looseness and looseness in the support portion of the slider mechanism in the case occur.

  If the slider mechanism is wobbled, if the body vibration is applied during normal use when the movable panel stands up at the front of the case, the movable panel itself will wobble, resulting in the appearance value of the product. Furthermore, there is a risk that the slider mechanism and the movable panel will rattle and become annoying.

  Therefore, the one described in Patent Document 1 is provided with a tension coil spring that pulls the slider mechanism into the case, and the elastic force of the spring causes looseness between the slider mechanism and the support portion, and the slider mechanism. The backlash between the gears is absorbed. Further, even when the movable panel is in a standing posture in front of the case, the movable panel is prevented from rattling by the biasing force of the spring.

  However, when the tension coil spring is provided, when the slider mechanism is moved forward, the tension coil spring gives an elastic resistance, and the load on the motor that operates the slider mechanism increases.

  The present invention solves the above-described conventional problems, and the posture of the movable panel is changed by the forward / backward movement of the slider mechanism, and at least when the slider mechanism is retracted into the case, An object of the present invention is to provide an electronic device having a movable panel that can prevent rattling and does not unnecessarily increase the load for moving the slider mechanism.

The present invention includes a case main body, a slider mechanism that moves forward and backward in and out of the case main body, a movable panel that is provided in front of the case and changes its posture as the slider mechanism moves forward and backward, and the slider In an electronic device having a drive device for moving the mechanism forward and backward,
The slider mechanism, the movement direction and at intervals in a direction intersecting disposed a drive slider and non-driven slider to move together, power from the drive unit gives et al is in the drive slider,
In the case, there is provided linkage means that is operated by being pushed by the drive slider that moves inward of the case, and the non-drive slider is pushed by the linkage means when pushed by the drive slider. It is characterized by this.

  According to the present invention, when the slider mechanism is moved inward of the case, the driving slider and the non-driving slider receive a pressing reaction force from the linking means, so that rattling of the slider mechanism can be prevented. In addition, since it is not necessary to use a spring for pulling the slider mechanism into the case, an increase in the load on the motor can be prevented. However, the present invention does not exclude the use of a biasing member such as a spring that pulls the slider mechanism inward of the case together with the linkage means.

  In the present invention, the driving slider and the non-driving slider may be connected and integrated with each other, or the driving slider and the non-driving slider may be separate members, It may be directly or indirectly connected to the movable panel.

  For example, the linkage means is a lever that contacts both the drive slider and the non-drive slider, and the lever is between a contact portion with the drive slider and a contact portion with the non-drive slider. It can be configured as having a rotation fulcrum and being rotatably supported.

Alternatively, the linking means includes a first lever that the driving slider contacts and a second lever that the non-driving slider contacts, and the first lever and the second lever are connected via a gear. The first lever is pivotally supported with a pivot point between a portion that contacts the driving slider and the gear, and the second lever is a portion that contacts the non-driving slider. A rotation fulcrum is provided between the gear and the gear, and the rotation can be supported .

  Further, the movable panel assumes an inclined posture in front of the case as the slider mechanism advances, and takes a standing posture as the slider mechanism moves backward, and the linkage means pushes the non-driven slider toward the inside of the case. The movable panel in the standing posture can be pressed against the front part of the case.

  In the above means, the movable panel can be pressed against the front portion of the case by both the driving slider and the non-driving slider, and the posture of the movable panel is stabilized.

  Further, a pressing force in at least a direction crossing the moving direction of the non-driving slider may act on the non-driving slider from the linkage means.

  As described above, when the non-driving slider is pressed in a direction crossing the moving direction, it is possible to effectively prevent the non-driving slider moving back and forth from shaking.

Furthermore, the linking mechanism is always being energized is preferably a direction approaching to the driving sliders.

  In addition, when at least a part of the linkage means has an elastic body, the linkage means is pressed against the non-driven slider by using an elastic force, and the slider mechanism moves to the inside of the case. Therefore, it is possible to avoid the occurrence of a locked state with the linking means.

  Further, the present invention is effective in the case where the movable panel is in a standing posture at the front portion of the case body when the drive slider moves into the case and the linkage means is pushed.

  According to the present invention, it is possible to prevent rattling of the driving slider and the non-driving slider using the linkage means when the driving slider is moving inward of the case. Therefore, in most of the operation modes of the electronic device, in most cases, the slider mechanism and the movable panel are moved by setting the state in which the slider mechanism is moved inward as the normal use state in which the movable panel is in the standing posture. The device can be used in a state where no rattling occurs.

  In the present invention, the linkage means operates when the drive slider moves inward of the case body, and the drive slider and the non-drive slider are pushed. It can prevent the posture of the panel from becoming unstable.

  Inside the case body 1 is housed a mechanical deck device (not shown) for driving a recording medium such as a CD, MD or cassette tape. An electric board 30 is fixed to the bottom surface 2 of the case. The electric board 30 includes a driving circuit for the mechanical deck device, a storage element such as a flash memory, and a communication circuit such as various tuners. A drive control circuit for the slider mechanism 20 is mounted. A slider driving device 28 having a speed reduction mechanism including a motor 40 and a worm gear 48 and a spur gear 33 is installed on the bottom surface 2 of the case.

  The slider mechanism 20 is formed of a thin sheet metal material, and has a U-shape when seen in a plan view as shown in FIG. This shape is a shape that does not interfere with the electric board 30, the slider driving device 28, and the mechanical deck device. The slider mechanism 20 is divided into three parts according to its function, and a slider connection that connects the drive slider 21 having the rack teeth 41 that mesh with the spur gear 33, the non-drive slider 31, and the drive slider 21 and the non-drive slider 31. A portion 49 is provided.

  The drive slider 21 and the non-drive slider 31 have a long shape extending in the Y1-Y2 direction, which is the forward / backward movement direction of the slider mechanism 20, and are formed in parallel to each other. The driving slider 21 and the non-driving slider 31 have sliding holes 23, 24, 25, and 26 that are elongated holes extending in the forward and backward directions, respectively. Pins 34, 35, 36, and 37 fixed to the case bottom surface 2 are inserted, and the driving slider 21 and the non-driving slider 31 are supported on the case bottom surface 2 so as to be slidable in the Y1-Y2 direction.

Is formed. A fitting portion 32 that opens rearward is formed at the end of the non-driving slider 31 on the Y2 side.

  The slider mechanism 20 is driven by the slider drive device 28, and moves forward and backward in the front-rear direction (Y1-Y2 direction) of the case body 1 as the motor 40 rotates forward and backward.

  The lever mechanism 90 functioning as the linking means is a long member formed of a thin sheet metal and having an L-shaped bent portion indicated by a lever wall 100 and a pressing portion 91 as shown in FIG. . The pressing portion 91 can come into contact with the pressing portion 22 that is an end portion of the drive slider 21 that moves backward and approaches the inside of the case body 1. Further, the tapered portion 94 formed in the lever head 93 having a wedge-shaped tip shape can abut on the pressing portion 52 of the fitting portion 32 of the non-driving slider 31.

  The lever mechanism 90 has a fulcrum shaft 92 fixed to the case bottom surface 2 at an intermediate position between a pressing portion 91 that is a contact portion with the driving slider 21 and a pressing portion 52 that is a contact portion with the non-driving slider 31. It is rotatably supported by. Further, the lever mechanism 90 is always urged in the A direction (clockwise) by a lever spring 98 formed of a torsion spring. The lever spring 98 is inserted into the fulcrum shaft 92, one end is locked to the lever wall 100, and the other end is locked to a lever spring stopper 99 installed on the case bottom surface 2.

  When the driving slider 21 and the non-driving slider 31 move forward in the Y1 direction and away from the lever mechanism 90, the lever mechanism 90 is rotated in the A direction by the urging force of the lever spring 98, and the end portion on the X1 side is the bottom surface 2 of the case. The lever mechanism 90 does not rattle or rotate even if unnecessary vibrations are transmitted to the case body 1 from the outside because it is stabilized in contact with the stopper pin 101 projecting from the lever. . In addition, the installation direction of the lever spring 98 may be changed, and the urging direction may be set to the B direction.

  The movable panel 60 is a thin hexahedron made of synthetic resin or the like, in which a display device such as a liquid crystal display panel is housed, and an operation button or the like is disposed on the front surface indicated by the panel front portion 62.

And are pivotally connected. Further, link fulcrum shafts 45 and 47 provided at the rear ends of the links 42 and 43 are rotatably connected to link fulcrum holes (not shown) formed at the front end of the slider mechanism 20.

Next, the operation of this in-vehicle electronic device will be described.
FIG. 4 shows a state when the recording medium is inserted into or ejected from the case main body 1. In this state, the slider mechanism 20 moves forward (Y1 direction) inside the case main body 1 as shown in FIG. The forward movement force is applied to the movable panel 60 via the links 42 and 43, and the movable panel 60 rotates in the direction D to a position that does not hinder the insertion and ejection of the recording medium. The panel front part 62 and the case bottom surface 2 which are surfaces having devices and operation buttons are in a substantially parallel horizontal posture. At this time, the recording medium can be inserted into or discharged from the case body 1.

  From this state, as shown in FIG. 1, when the slider mechanism 20 moves to the rear (Y2 direction) moving end, the movable panel 60 is pulled backward by the links 42 and 43 as shown in FIG. It becomes the attitude | position which rotated in the C direction to the position parallel to the surface of the said case main body front part 3, and stood up. And the surface which has the display apparatus and operation button provided in the panel front part 62 is orient | assigned ahead, A display apparatus can be visually observed from the front, and an operation button can be operated now. Further, the insertion / ejection port 8 can be covered with the movable panel 60.

  In this in-vehicle electronic device, as shown in FIGS. 1 and 2, the state in which the movable panel 60 is in the standing posture and installed on the front side of the case body front portion 3 is the main use state and the state when the device is stopped. Yes, this posture occupies the longest time among the various operation modes. In this embodiment, the lever mechanism 90 functioning as a linking means allows the slider mechanism 20 and the movable panel 60 connected to the slider mechanism 20 to be connected to the slider mechanism 20 as described later in the main use state and the stop state. It can prevent rattling.

  The movement of the slider mechanism 20 in the advancing / retreating direction (Y1 and Y2 directions) is performed by the power of the motor 40 constituting the slider driving device 28. In FIG. 3, when the motor 40 rotates in the forward and reverse directions, the worm gear 48 and the spur gear 33 installed on the rotation shaft of the motor 40 rotate. Then, when the rotational force of the spur gear 33 is applied to the rack teeth 41 provided on the drive slider 21, the entire slider mechanism 20 can move in the forward / backward direction indicated by Y1 or Y2.

  As shown in FIG. 3, when the slider mechanism 20 is located at the moving end on the front side of the case body 1, neither the driving slider 21 nor the non-driving slider 31 is in contact with the lever mechanism 90, and the lever mechanism 90 is The urging force of the lever spring 98 is constantly received and rotated in the direction A, and is stationary at the position where it abuts against the stopper pin 101. Then, when the movable panel 60 shifts to a standing posture by a user operation or the like from this state, as shown in FIG. 2, immediately before the slider mechanism 20 completes moving to the moving end in the backward direction in the Y2 direction, as shown in FIG. The pressing portion 22 which is the end portion of the slider 21 presses the pressing portion 91 of the lever mechanism 90, and the lever mechanism 90 is rotated in the B direction as shown in FIG. At this time, the lever head 93 presses the fitting portion 32 formed on the non-driving slider 31.

  That is, the tapered portion 94 provided in the lever mechanism 90 presses the pressing portion 52 formed in the fitting portion 32 of the non-driven slider 31. Therefore, the component force that is pressed in the Y1 direction by the taper shape of the taper portion 94 from the lever mechanism 90 to the fitting portion 32 of the non-drive slider 31 and the X2 direction that intersects the moving direction of the non-drive slider 31. The component force which pushes to acts.

  When the non-driving slider 31 is pressed in both the Y1 direction and the X2 direction, rattling of the non-driving slider 31 is prevented, and the reaction force when the pressing portion 22 presses the pressing portion 91 of the lever mechanism 90. Therefore, rattling of the drive slider 21 is also prevented. In particular, when the pressing force in the X2 direction intersecting the moving direction acts on the non-driving slider 31, the sliding holes 23, 24, 25, 26 and the pins 34, 35 fixed to the case bottom 2 are provided. , 36, and 37 can be prevented from rattling.

  As a result, the slider mechanism 20 and the movable panel 60 do not rattle in the X and Y directions, and no rattling sound is generated.

  Since the lever mechanism 90 is pressed by the slider mechanism 20 immediately before the movement of the slider mechanism 20 in the Y2 direction is completed, the pressing force of the lever mechanism 90 hardly becomes an operation load of the slider mechanism 20. Absent.

Next, a second embodiment shown in FIG. 5 will be described.

The partial gear 74 and the partial gear 79 mesh with each other. Although not shown, one of the first lever 71 and the second lever 76 is urged by a spring in one rotational direction (D direction or G direction).

  When the drive slider 21 moves to the moving end in the retreat direction, the first lever 71 is pushed by the drive slider 21 and rotates counterclockwise (E direction), and accordingly, the second lever 76 is turned clockwise. It rotates in the direction (F direction). As a result, the protruding portion 532 provided on the non-driving slider 531 is pressed in the Y2 direction by the tip 77 of the second lever 76.

When the slider mechanism 20 is advanced from this state, first by the biasing force of the spring, D second lever 71 and 76, respectively, so rotates in the G direction, the tip portion 77 of the second lever 76 The movement of the non-driving slider 531 is not hindered.

  In this embodiment, the non-driving slider 531 is pushed in the same Y2 direction by using the force that the driving slider 21 moves in the Y2 direction, so that the movable panel 60 is in a standing posture and the front surface of the case body front portion 3. Will be pressed against. Therefore, the movable panel 60 in the standing posture and the case body 1 can be in close contact with each other, and the posture is stabilized without the movable panel 60 being inclined with respect to the case body front portion 3.
