Description

Panel drive device

This invention relates to a panel drive device that changes the rotational speed in multiple stages according to the translation amount of the panel when the panel is opened.

In a conventional in-vehicle panel drive device, in order to emphasize designability, the front panel of the panel drive device and the design panel in the vehicle are arranged on the same curve, and the front panel is almost in the design panel in the vehicle. Some are configured to be stored without gaps. In this case, if the panel is opened only by the pivoting operation, the panel comes into contact with the surrounding design panel. Therefore, when opening the panel, it is necessary to translate the panel to a position protruding from the design panel, and then move to a rotation operation (see, for example, Patent Document 1).

In the panel driving device disclosed in Patent Document 1, one end is pivotally connected to the lower part of the panel and is movable in the front-rear direction, and an arm whose one end is pivotally connected to the upper part of the panel; And a power transmission mechanism interposed between the arm and the slide member. In this power transmission mechanism, when the slide member is moved forward from the retracted position, the arm is translated substantially integrally with the slide member, and the panel is erected. The panel is tilted by relatively translating.

Japanese Patent No. 3821325

As described above, the panel driving device disclosed in Patent Document 1 employs two-stage driving in which the panel is translated and then rotated. However, there has been a problem that the panel vibrates due to a sudden change in the operation from the translation operation to the rotation operation, and a collision sound of the component parts is generated by this vibration.

Further, in the power transmission mechanism of the conventional panel drive device, the arm pin attached to the arm is engaged with the cam hole for switching the movement / fixation of the arm via the guide hole formed in the slide member. At this time, the arm pin that is switched to the fixed state by the cam hole when the panel is rotated is prevented from coming into contact with the slide member, and the arm pins are held together with the cam hole, and therefore, reinforcing bending is provided on both sides of the slide member. In addition, it is necessary to lengthen the guide hole by the amount of sliding when the panel is rotated. Therefore, the slide member becomes thick in the height direction, and it is difficult to reduce the thickness, and there is a problem that the strength of the slide member cannot be maintained.

The present invention has been made in order to solve the above-described problems, and the operation has been changed while the front panel is housed in the design panel in the vehicle with almost no gap so as not to impair the design in the vehicle. It is an object of the present invention to provide a panel drive device that can prevent the vibration of the panel due to the above, prevent the occurrence of collision noise of component parts due to the vibration, and achieve a reduction in thickness.

A panel drive device according to the present invention includes a panel storage portion provided on an end surface of the main body device, a panel which is stored in the panel storage portion and can be opened and closed on the side opposite to the main body device side, and a first fulcrum of the panel A slide base that is pivotably coupled to the main body device and movable in the panel mounting direction, an arm pivotally coupled to the second fulcrum of the panel, and an arm provided at the other end of the arm A pin, a cam portion having a cam groove fixed to the main body device and engaged with an arm pin, and a slide base formed between the first position and the second position by movement of the slide base; Is provided with an engaging portion that is disengaged from the arm pin when the arm pin is engaged and is located between the second position and the third position, and the cam groove is further toward the panel side. Down at large tilt angle This is a shape that translates while rotating the panel via the arm pin and protrudes and retracts from the panel storage part, and prevents the back end of the panel from contacting the surroundings when protruding and storing from the panel storage part The notch part to be formed is formed.

According to the present invention, since it is configured as described above, the front panel is accommodated in the design panel in the vehicle with almost no gap so as not to impair the design in the vehicle. Therefore, it is possible to prevent the occurrence of collision noise of the component parts due to this vibration, and it is possible to reduce the thickness.

Embodiment 1 FIG.
As shown in FIG. 1, the panel drive unit 1 is provided with a panel housing 3 on the end surface (for example, the front surface) of the main body device 2. The panel housing 3 is provided with a media insertion slot 4 through which a recording medium such as a music CD (Compact Disc) or a DVD (Digital Versatile Disc) is taken in and out of the main body device 2.
In addition, the panel housing 3 is provided with a panel 5 that can be opened and closed on the side opposite to the main body device 2 side (for example, in front of the main body device 2). A display unit 6 and operation keys 7 are arranged on the panel 5. The panel 5 is stored in a standing state in the panel storage unit 3 in the panel storage state. On the other hand, when the recording medium is taken in and out of the main unit 2, as shown in FIG. 1, the panel 5 is opened to expose the media insertion opening 4 (panel open state).

Further, in order to emphasize designability, the panel 5 is arranged on the same curve as the edge of the design panel 2a of the main body device 2 and the panel storage unit 3, and is stored in the panel storage unit 3 with almost no gap. Therefore, when the panel 5 is opened, in order to prevent contact with the panel storage unit 3, it is necessary to shift the panel 5 in the panel storage state to a position protruding from the panel storage unit 3 and then to move to a rotation operation.

Next, a mechanism for opening and closing the panel 5 in the panel drive device 1 as described above will be described with reference to FIGS. 2, 3 and 8 to 12 show a state in which a part of the guide member 10 (the restriction wall 18) is removed in order to clearly show the engagement relationship between an arm pin 14 and an inclined groove 15 which will be described later ( (See FIGS. 6 and 7 for the structure of the guide member 10).
As shown in FIGS. 2 and 3,

engagement protrusions

5 a and 5 b are formed on the upper and lower portions of both side surfaces of the panel 5. Further, as shown in FIG. 8, a cutout portion 5 c is formed at the lower back end of the panel 5.

As shown in FIGS. 2 and 3, a U-shaped slide base that can move in the panel mounting direction with respect to the main unit 2 (one end can protrude from the panel storage unit 3) is provided on the back of the panel 5. 8 is provided. An engagement hole 8a is formed at one end of both sides of the slide base 8, and an engagement protrusion (first fulcrum) 5a is rotatably connected.

Bending portions 9 are provided on both sides of the slide base 8. On the other hand, on the outside of both sides of the slide base 8, a guide member 10 of a resin molded product is fixed to a chassis (not shown) on the bottom surface of the main body device 2. A guide groove 11 extending in the front-rear direction is formed on the inner surface of the guide member 10. The bending portion 9 is engaged with the guide groove 11.
As described above, the slide base 8 is configured to be movable only in the front-rear direction via the rack gear 12 by the driving force of the electric driving device (not shown) by the bending portion 9 being engaged with the guide groove 11. Yes. The bent portion 9 also has a function of increasing the strength of the slide base 8.

In addition, a substantially L-shaped arm 13 whose one end can protrude and retract from the panel storage unit 3 is provided on the back surface of the panel 5. An engagement hole 13a is formed at one end of the arm 13, and is rotatably connected to an engagement protrusion (second fulcrum) 5b. Further, an arm pin 14 is formed on the other end side of the arm 13 so as to be rotatable with an inclined groove 15 described later. The arm pin 14 passes through the inclined groove 15 and protrudes to the lower part of both sides of the slide base 8.

Further, the guide member 10 has a cam portion 10a. The cam portion 10a is formed with an inclined groove (cam groove) 15 that opens from the inside toward the inner surface. The groove width of the inclined groove 15 is slightly larger than the diameter of the arm pin 14 so that the engaged arm pin 14 can slide. As shown in FIG. 4, the inclined groove 15 is composed of a plurality of inclined grooves 15a to 15c having different inclination angles. The inclined grooves 15a to 15c satisfy the relationship of the inclination angle a of the first inclined groove 15a <the inclination angle b of the second inclined groove 15b <the inclination angle c of the third inclined groove 15c, and the inclined groove 15 is inclined forward. The angle is increasing and descending. A part or all of the inclined groove 15 may be formed in an arc shape.

Further, as shown in FIGS. 2 and 3, engaging portions 16 for engaging and releasing the arm pins 14 according to the position of the slide base 8 are formed on the back surfaces of both sides of the slide base 8. As shown in FIG. 5, the engaging portion 16 is formed in an uneven shape having a first contact portion 16a and a second contact portion 16b.

The first contact portion 16a is a wall surface that can be in contact with the arm pin 14 located at a position other than the front end portion of the inclined groove 15 (the end point 15c1 of the third inclined groove 15c shown in FIG. 4). The first abutting portion 16a protrudes upward from the bottom surface of the slide base 8 by less than the diameter of the arm pin 14 and more than the radius (D>h1> D / 2).
On the other hand, the second contact portion 16 b is a wall surface that can contact the arm pin 14 in the entire range of the inclined groove 15. The second abutting portion 16b is formed in front of the first abutting portion 16a and protrudes downward from the bottom surface of the slide base 8 by about the diameter of the arm pin 14 (h2≈D).
The groove width between the first contact portion 16a and the second contact portion 16b is slightly larger than the diameter of the arm pin 14 (D + α).

Here, the positional relationship between the arm pin 14, the inclined groove 15 and the engaging portion 16 is such that, in the panel storage state (FIG. 8), the arm pin 14 is connected to the rear end portion of the inclined groove 15 (the first inclined groove 15a shown in FIG. 4). It is located at the starting point 15a1) and is fully engaged with the engaging portion 16. On the other hand, in the panel rotation state (FIG. 12), the arm pin 14 is located at the front end portion of the inclined groove 15 and is completely out of the engagement portion 16 (the engagement with the engagement portion 16 is released). ). In the panel rotation state, the arm pin 14 is in contact with the bottom surface of the slide base 8 and is sandwiched between the slide base 8 and the inclined groove 15.

Further, as shown in FIGS. 2 and 3, arm springs 17 are fixed to the chassis at lower portions of both side portions of the slide base 8. The arm spring 17 always biases the arm pin 14 projecting from the lower part of both sides of the slide base 8 toward the slide base 8.

6 and 7, the guide member 10 is provided with a regulating wall 18 at a position facing the formation surface (inner surface) of the inclined groove 15. The regulating wall 18 regulates the movement of the arm 13 in the side surface direction and prevents the arm 13 from being detached from the guide member 10. The restricting wall 18 is formed with an insertion hole 19 for inserting the arm 13 into the guide member 10 and engaging the arm pin 14 with the inclined groove 15 at a position facing the rear end of the inclined groove 15. Also, an opening surface 20 that opens from the bottom surface (chassis mounting surface) along the front end side surface between the formation surface of the inclined groove 15 and the regulation wall 18 and guides the arm 13 inserted through the insertion hole 19. Is formed. The restriction wall 18 is formed of an elastic wall surface that urges the arm 13 toward the formation surface of the inclined groove 15 in order to hold the arm 13 assembled to the guide member 10.

Next, assembly of the arm 13 to the guide member 10 configured as described above will be described.
In assembling the arm 13 to the guide member 10, first, as shown in FIG. 6A, the arm 13 is inserted into the guide member 10 through the insertion hole 19, and the arm pin 14 is inserted into the rear end of the inclined groove 15. Engage with the part.
Next, as shown in FIG. 6B, the arm 13 is moved to the front side of the guide member 10 along the opening surface 20. At this time, the arm pin 14 moves to the front end along the inclined groove 15.
Next, as shown in FIG. 6C, the arm 13 is rotated upward with the arm pin 14 as a fulcrum. Thereby, the arm 13 becomes a state as shown in FIG. 6D and can be assembled to the guide member 10.

As described above, by assembling the arm 13 to the guide member 10 through the insertion hole 19 and the opening surface 20, the assemblability can be improved. Further, when the arm 13 is assembled to the guide member 10, a special attachment member is not necessary, and therefore the number of parts can be reduced. Further, since the restricting wall 18 is an elastic wall surface and the arm 13 is always urged toward the surface on which the inclined groove 15 is formed, the arm 13 can be held without rattling, and the arm 13 can be held by vibration or the like. It is possible to suppress the occurrence of rattling. In addition, even when a variation occurs in the assembly relationship between the panel 5 and the arm 13, the variation can be absorbed by the restriction wall 18 being bent.

Next, the operation of the panel drive device 1 configured as described above will be described with reference to FIGS. First, the operation when opening the panel 5 in the panel storage state will be described.
First, in the panel storage state shown in FIG. 8, when the slide base 8 is advanced from the retracted position (first position) by the electric drive device, the panel 5 moves from the state of FIG. 8 to FIG. It moves gently downward along the first inclined groove 15a from the rear end of the inclined groove 15 while being translated. Along with this, the arm 13 moves slowly downward while being translated. Therefore, the panel 5 translates while gently rotating so that the display unit 6 faces upward from the standing state.

Although the panel 5 translates while gently rotating from the panel storage state, the upper part of the panel 5 rotates downward while moving in the sliding direction of the slide base 8 and therefore does not come away from the panel storage unit 3 and comes into contact. Further, the lower end of the back surface of the panel 5 is rotated so as to come into contact with the lower portion of the panel storage unit 3 by rotating the panel, but the notch 5c of the panel 5 prevents contact between the panel 5 and the panel storage unit 3. Therefore, the rotation operation of the panel 5 is not impaired.
Further, since the arm pin 14 is always urged toward the slide base 8 by the arm spring 17, the arm 13 does not rattle and the generation of noise due to contact between components due to vibrations such as rattle noise is prevented. can do.

Thereafter, when the slide base 8 is further advanced, the panel 5 shifts from the state of FIG. 9 to FIG. 10, and the arm pin 14 moves further downward while being translated along the second inclined groove 15b. Here, since the inclination angle of the second inclined groove 15b is steeper than that of the first inclined groove 15a, the arm pin 14 moves downward earlier than moving on the first inclined groove 15a although it is gentle. Along with this, the arm 13 also moves downward while being translated. Therefore, the panel 5 translates while increasing the rotation speed.

Thereafter, when the slide base 8 is further advanced, the panel 5 shifts from the state of FIG. 10 to FIG. 11, and the arm pin 14 moves further downward while being translated along the third inclined groove 15c. Here, since the inclination angle of the third inclined groove 15c is steeper than that of the second inclined groove 15b, the arm pin 14 moves downward earlier. Along with this, the arm 13 also moves downward while being translated. Therefore, the panel 5 translates while further increasing the rotational speed. Further, as the arm pin 14 moves downward, the amount of engagement with the engaging portion 16 gradually decreases.

Thereafter, when the slide base 8 is further advanced to a predetermined position (second position), the panel 5 shifts from the state of FIG. 11 to FIG. 12, and the arm pin 14 reaches the front end of the inclined groove 15, It will be located at the lower end. Therefore, the arm pin 14 is released from the engaged state with the engaging portion 16. As a result, the panel 5 protrudes from the panel storage unit 3.

At this time, the arm pin 14 is held between the bottom surface of the slide base 8 and the front end portion of the inclined groove 15. Thus, by fixing the position of the arm pin 14 on the bottom surface of the slide base 8, it is not necessary to provide a separate member for fixing the position of the arm pin 14, and the thickness of the slide base 8 in the height direction is reduced. Therefore, the panel drive device 1 can be thinned.
In addition, since the first abutting portion 16a is smaller than the diameter of the arm pin 14 and larger than the radius, the movement distance downward of the arm pin 14 necessary for releasing the engagement can be minimized, and the panel drive The apparatus 1 can be thinned.

Thereafter, when the slide base 8 is further advanced, as shown in FIG. 12, since the position of the arm pin 14 is fixed by the bottom surface of the slide base 8 and the inclined groove 15, only the slide base 8 translates. As a result, the positions of the first fulcrum and the second fulcrum of the panel 5 in the front-rear direction are relatively separated according to the slide amount of the slide base 8, and the arm 13 pivots downward with the arm pin 14 as a fulcrum. Therefore, the panel 5 rotates so that the display unit 6 faces upward at the maximum rotation speed.

Thereafter, when the slide base 8 is moved forward to the forward movement position (third position), the panel 5 reaches the maximum tilt angle and the panel is opened. As a result, the media insertion slot 4 is exposed, so that the user can insert and remove the recording medium from the media insertion slot 4 in the main unit 2.

Next, the operation when storing the panel 5 in the panel open state will be described.
First, when the slide base 8 is moved backward from the forward position by the electric drive device in the panel open state, the position of the arm pin 14 is fixed by the bottom surface of the slide base 8 and the inclined portion 15 as shown in FIG. Since 16 does not engage the arm pin 14, only the slide base 8 translates. Accordingly, the positions of the first fulcrum and the second fulcrum of the panel 5 in the front-rear direction are relatively close according to the slide amount of the slide base 8, and the arm 13 rotates upward with the arm pin 14 as a fulcrum. Therefore, the panel 5 rotates in the standing direction.

At this time, the sliding force necessary to erect the panel 5 in the panel open state is maximized when it starts to rotate. Here, as shown in FIG. 13A, when the position of the pivot fulcrum (arm pin 14) of the arm 13 is arranged above the bottom surface of the slide base 8, the rotational force of the arm 13 obtained by the sliding force F ( Vector component) is F1. On the other hand, as in the panel drive device 1 according to Embodiment 1 shown in FIG. 13B, the position of the pivot fulcrum of the arm 13 is determined from the bottom surface of the slide base 8 and the pivot fulcrum (engagement protrusion 5a) of the panel 5. Is also arranged on the lower side, the rotational force (vector component) of the arm 13 obtained by the sliding force F is F2 (> F1). In other words, by arranging the pivot fulcrum of the arm 13 below the bottom surface of the slide base 8 and the pivot fulcrum of the panel 5, the rotational force for the panel 5 can be obtained efficiently and the load can be reduced. .

Thereafter, when the slide base 8 is further retracted, the arm pin 14 contacts the second contact portion 16b and moves upward along the third inclined groove 15c as shown in FIG. Thereafter, the arm pin 14 is fitted into the engaging portion 16.
At this time, since the arm pin 14 is biased toward the slide base 8 by the arm spring 17, the arm pin 14 is engaged with the engaging portion 16 even when the amount of contact with the second contact portion 16b is small. It can be made easy.

Thereafter, when the slide base 8 is further retracted, the arm pin 14 moves upward while being translated along the third inclined groove 15c, the second inclined groove 15b, and the first inclined groove 15a as shown in FIGS. Moving. As a result, the panel 5 translates while gently rotating, returns to the standing state, and is stored in the panel storage unit 3.

As described above, according to the first embodiment of the present invention, the arm pin 14 is engaged, and the inclined groove 15 that descends toward the front with a large inclination angle is provided in the guide member 10. Accordingly, since the engaging portion 16 that engages / releases with the arm pin 14 is provided on the slide base 8, the panel 5 is translated from the standing state while gradually rotating, and protrudes from the panel storage portion 3 ( The position of the panel 5 in the front-rear direction at the second fulcrum is relatively distant from the position in the front-rear direction at the first fulcrum and after being relatively distant from the panel storage unit 3). Transition. Therefore, the panel 5 can be opened without impairing the design, and the vibration of the panel 5 due to the operation change can be prevented, and the occurrence of the collision noise of the component parts due to this vibration can be prevented. Further, the thickness can be reduced.

Further, in the conventional panel drive device, the slide member (slide base) is sandwiched between the bracket and the arm in which the cam hole (cam groove) is formed, and a bending portion is provided in order to secure a rotation space of the arm. I couldn't. Therefore, the subject that the intensity | strength of a slide base became weak occurred.
However, in the panel drive device 1 according to the first embodiment, the guide member 10 is arranged outside the slide base 8 and the arm 13 is arranged outside the inner side surface of the guide member 10. Does not come into contact with the bent portion 9, and the slide base 8 having a simple shape and high strength can be obtained.
Further, in the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.

The panel driving device according to the present invention prevents the vibration of the panel due to the operation change, prevents the occurrence of the collision noise of the component parts due to the vibration, and can reduce the thickness, so that the panel is opened. At this time, it is suitable for use in a panel drive device for rotating the panel after translation.
