Description

  The present invention relates to a vehicle lid opening / closing mechanism used for opening / closing an opening provided in a vehicle interior member.

  2. Description of the Related Art Conventionally, lids that can be opened and closed are installed on various interior parts of a vehicle. For example, a glove box used as an accessory case is installed on the front portion of the instrument panel on the passenger seat side. In addition, a cup holder, a portable holder, and the like are disposed near the center of the instrument panel. Hereinafter, a conventional lid opening / closing mechanism for a vehicle will be examined focusing on the cup holder.

  A rotary cup holder in which a lid opens and closes with an opening / closing shaft as a fulcrum is configured to include a lid that can be rotated around a support shaft and a guide for opening and closing the lid. In addition, in this type of cup holder, it is necessary to consider that the beverage container does not wobble due to vibrations, inertial forces, and the like that are applied when the vehicle travels. That is, it is desirable to provide an opening adjustment mechanism so that the lid is appropriately held at an opening corresponding to the beverage container size when the lid is opened. In order to meet these needs, proposals have been made to set an opening adjustment mechanism using springs, cams, etc., but all of them are complicated in construction, making it difficult to secure installation space and increasing the number of parts. There is a disadvantage of incurring cost increase.

Moreover, in the glove box described in the following Patent Document 1, a pivot pin serving as a rotation center is provided at the lower part of the side surface, and a guide pin that integrally moves in an arc shape in accordance with the opening / closing operation is provided at the upper side surface. . On the other hand, a guide pin is inserted in the instrument panel, and an arcuate guide groove is formed along the movement locus of the guide pin. Then, a concentric arc-shaped elongated hole is formed immediately below the guide groove so that the middle portion of the guide groove can be elastically deformed downward so that sliding resistance is applied to the guide pin during the movement of the guide pin. ing. As another disclosed example, a spring having a convexly curved shape is arranged separately at a position facing the side of the glove box, and when the guide pin moves, the middle part of the spring is bent downward during the movement. As a result, sliding resistance is applied to the guide pin.

[First Embodiment]
Hereinafter, the cup holder 10 of the first embodiment to which the vehicle lid opening / closing mechanism according to the present invention is applied will be described with reference to FIGS. In these drawings, an arrow FR appropriately shown indicates the vehicle front side, and an arrow UP indicates the vehicle upper side.

  The side view which shows the whole structure of the cup holder 10 which concerns on this embodiment is shown by FIG. As shown in this figure, the cup holder 10 is provided at a predetermined position of an instrument panel 12 as a vehicle interior member. A recessed portion 14 is formed at a predetermined position of the instrument panel 12 as an opening that can accommodate a beverage container. The recess 14 is formed in a substantially quadrant shape in a side view, and includes a vertical wall 14A and a bottom wall 14B. The beverage container is placed on the bottom wall 14B.

  The concave portion 14 is opened and closed by a lid 16 formed in a convex curved shape in a side view. The lid 16 is pivotally supported by the instrument panel 12 so as to be rotatable around a spindle 18 set at the lower end. A pair of left and right guides 20 are formed on both sides of the upper edge side of the lid 16 as guide members extending in an arc shape along a circumference having a predetermined diameter with the support shaft 18 as the center.

  On the other hand, a slit (not shown) through which the pair of left and right guides 20 can be inserted is formed on the upper end side of the vertical wall 14A of the recess 14. In addition, locking pins 22 are erected in the vicinity of the upper end portion of the vertical wall 14 </ b> A corresponding to each guide 20. The axial direction of the locking pin 22 is in a positional relationship parallel to the axial direction of the support shaft 18.

  A coil portion 24A of a torsion coil spring 24 as an urging means is wound around the locking pin 22. 2A, one end 24B of the torsion coil spring 24 is bent and is inserted and locked in a small hole 26 (see FIG. 1) formed in the vertical wall 14A. ing. Further, the other end 24 </ b> C of the torsion coil spring 24 is bent in a substantially V shape, and the tip R portion of the bent portion is in contact with the outer peripheral surface 20 </ b> A of the guide 20 in a point contact state.

  Returning to FIG. 1, in this embodiment, on the line segment Q connecting the contact point P to the outer peripheral surface 20 </ b> A of the guide 20 of the other end 24 </ b> C of the torsion coil spring 24 and the support shaft 18 of the lid 16. The dimensions and component layout (arrangement) of each part are determined so that the line of action of the biasing force (elastic restoring force) F of the torsion coil spring 24 is located. In this embodiment, since the torsion coil spring 24 is disposed on the upper side of the outer peripheral surface 20A of the guide 20, the biasing force F is directed toward the support shaft 18 on the lower side of the guide 20 (that is, in the radial direction). Acts vertically on the inside. As a result, the guide 20 is configured to receive a certain sliding resistance in all positions from the fully closed state of the lid 16 (the position indicated by the two-dot chain line in FIG. 1) to the fully open state (the position indicated by the solid line in FIG. 1). .

  Supplementally, the urging force F of the torsion coil spring 24 acting on the guide 20 can be regarded as a bending moment (direction is counterclockwise) around the locking pin 22. The line segment Q is one of a perpendicular line or a radial line of the support shaft 18, and is also a normal line of the outer peripheral surface 20 </ b> A of the guide 20.

  In the present embodiment, the torsion coil spring 24 in which the other end 24C is bent in a substantially V shape is used. However, the present invention is not limited to this, and as shown in FIG. The one end portion 28B may be a torsion coil spring 28 having the same configuration and the other end portion 28C formed in a spherical shape. In any of the torsion coil springs 24 and 28, the effect of causing smooth sliding resistance to act on the outer peripheral surface 20A of the guide 20 and the other end of the torsion coil spring is the outer peripheral surface of the guide 20. When sliding on 20A, the effect of preventing reversal due to catching on the outer peripheral surface 20A of the guide 20 is obtained.

  Next, the operation and effect of this embodiment will be described.

  The state shown in FIG. 11A is the fully closed state of the cup holder 70. 9A and 10A, the spherical other end portion 28C of the torsion coil spring 28 is in contact with the side surface of the starting end portion 76 of the track 72 (see FIG. 9A and FIG. 10A). 10 (A) is held at a neutral position indicated by a one-dot chain line n). The mechanical relationship between the guide 20 and the torsion coil spring 28 is the same as in the first embodiment described above, and the other end portion 28C of the torsion coil spring 28 abuts near the base of the guide 20. Thus, a biasing force F inward in the radial direction toward the support shaft 18 acts on the guide 20. As a result, a predetermined holding force is generated between the other end portion 28C of the torsion coil spring 28 and the outer peripheral surface 20A of the guide 20, and the lid 16 is held in the closed state. That is, also in this embodiment, the holding mechanism of the lid 16 is formed by two parts, the torsion coil spring 24 and the guide 20.

  When holding the beverage can 30 having a large capacity from this state, as shown in FIG. 11B, the lid 16 is rotated in the direction of arrow A, and the cup holder 70 is fully opened. At this time, as shown in FIGS. 9A and 10A, the spherical other end 28 </ b> C of the torsion coil spring 28 follows the side surface shape (round shape) of the start end portion 76 of the track 72. Then, it slides so as to trace the side surface 72A of the track 72 (see the forward path a in FIG. 9). At this time, the other end portion 28C of the torsion coil spring 28 enters the forward path a from the neutral position n (displaces in the width direction of the guide 20), so that the reaction force R ( The elastic restoring force which tries to return to the neutral position n is always acting. 10A and 10B, in these drawings, the guide 20 is grasped fixedly, and the torsion coil spring 28 is relatively moved in the longitudinal direction of the guide 20 so that it is drawn. It stands in the opposite relation to the actual movement.

  Even in the fully open state, the mechanical relationship between the guide 20 of the cup holder 70 and the torsion coil spring 28 is the same as the state shown in FIG. 11A, and the guide is in the full range from the fully closed state to the fully open state. A constant sliding resistance acts on 20.

  On the other hand, when the beverage can 32 having a small capacity is held, the lid 16 is set to the neutral state as shown in FIG. In this case, the lid 16 is once fully opened (the state shown in FIG. 11B), the beverage can 32 is accommodated in this state, and then the lid 16 is closed (arrow in FIG. 11C). B) is slightly rotated to adjust the opening. Looking at this state in relation to the track 72, first, as the lid 16 is opened, the other end 28C of the torsion coil spring 28 passes through the forward path a as shown in FIG. When the state is reached, the reaction force R of the torsion coil spring 28 described above at the end portion 78 of the track 72 enters the return path b (returns to the neutral position n) as shown in FIG. Thereafter, when the lid 16 is closed by a predetermined opening, the other end portion 28C of the torsion coil spring 28 ascends the end portion 78 of the track 72 and reaches the upper surface 72B of the track 72, and the upper surface of the track 72 along the return path b. Start sliding on 72B. When the return path b is slid by a predetermined distance, the other end portion 28 </ b> C of the torsion coil spring 28 is dropped into the engagement groove 74.

  When the other end portion 28C of the torsion coil spring 28 is dropped into the engagement groove 74, the spherical other end portion 28C is hooked on the vertical surface 74A, so that the lid 16 is opened from this position (FIG. 11C ) In the direction of arrow D) is hindered. However, since it is possible to ascend the inclined surface 74B, the closing operation of the lid 16 is not hindered. Therefore, the lid 16 can be held at an appropriate opening for holding the beverage can 32.

  When the cup holder 70 becomes unnecessary, as shown in FIG. 11D, after the beverage can 32 is taken out, the lid 16 is rotated in the closing direction (arrow C direction) to be in the fully closed state. do it.

  Thus, in the cup holder 70 according to the present embodiment, since the lock means (engagement groove 74) is newly added to the configuration of the first embodiment described above, the lid 16 is opened at a predetermined opening degree. After that, even if some load acts, it is possible to prevent the lid 16 from being inadvertently moved further in the opening direction and causing problems such as wobbling of the beverage can 32.

  Further, in the cup holder 70 according to the present embodiment, since the long convex track 72 is integrally provided on the upper surface 72B of the guide 20, the forward path a that slides on the side surface 72A of the track 72 when the lid 16 is opened. When the lid 16 is closed, it returns to the start end 76 through the return path b continuous with the forward path a and the terminal end 78 and does not intersect, that is, the other end 28C of the torsion coil spring 28 and the guide 20. , And the other end of the torsion coil spring 28 on the outer peripheral surface 20A of the guide 20 as compared with the case where the same path is used for the forward path and the backward path. Wear on the sliding surface with the portion 28C can be reduced. The fact that the wear of the sliding surface of the guide 20 can be suppressed means that the influence on the amount of elastic deformation at the time of contact of the other end portion 28C of the torsion coil spring 28 can be reduced. The sliding resistance at the time can be kept constant over a long period of time. As a result, according to the present embodiment, it is possible to improve the durability related to the sliding resistance when the lid 16 is opened and closed.

  Further, by changing the height through which the other end 28C of the torsion coil spring 28 passes between the forward path a and the return path b, the urging force of the torsion coil spring 28 is changed when the lid 16 is opened and closed. It becomes possible. For example, if the return path b is set higher than the forward path a as in the present embodiment, the urging force acting on the guide 20 from the other end portion 28C of the torsion coil spring 28 becomes weaker when opened and becomes stronger when closed. Therefore, the opening / closing operation of the lid 16 can be sharpened. As a result, according to the present embodiment, the opening / closing operability of the lid 16 can be improved.

  Furthermore, in this embodiment, since the track 72 is set on the upper surface 20A of the guide 20 and the lock means including the concave engagement groove 74 is provided on the track 72, the number of parts does not increase. The structure is not complicated. Therefore, the structure can be simplified and the cost can be reduced.

  In the present embodiment described above, the torsion coil spring 28 is used. However, as shown in FIG. 10C, the torsion provided with the other end of the shape matching the shape of the engagement groove 74. When the coil spring 80 is used, the lid 16 can be more effectively locked. Specifically, the torsion coil spring 80 includes, in addition to the coil portion 80A and the one end portion 80B, the other end portion 80C bent in a hook shape. The tip vertical portion of the other end portion 80C is locked in contact with the vertical surface 74A of the engaging groove 74, and the tip inclined portion of the other end portion 80C enters along the inclined surface 74B of the engaging groove 74. In this case, for the closing operation of the lid 16, the other end portion 80C of the torsion coil spring 80 can easily slide out on the inclined surface 74B of the engaging groove 74, but the lid 16 is opened. With respect to the operation, the vertical surface 74A of the engagement groove 74 is locked so that the tip vertical portion of the other end portion 80C of the torsion coil spring 80 is bitten, so that the lock is more effectively applied.

  Moreover, in this embodiment mentioned above, although the elongate convex track | orbit 72 which protrudes upwards from the upper surface 72B of the guide 20 was set, as shown in FIG. A configured track 82 may be used. Briefly, the track 82 includes a concave groove 84 that constitutes the forward path a, a concave groove 86 that is arranged in parallel with the concave path 84 and that constitutes the return path b, and ends of both concave grooves 84 and 86 on the lid 16 side. It consists of a start end portion 88 that connects each other diagonally and a terminal end portion 90 that connects the end portions on the guide tip side of both concave grooves 84 and 86 in the lateral direction, and is configured as a loop-like continuous groove. The other end portion 28 </ b> C of the torsion coil spring 28 is inserted into the start end portion 88. Accordingly, as the lid 16 is opened and closed, the other end portion 28C of the torsion coil spring 28 is “starting end portion 88 → concave groove 84 (forward path a) → terminal end portion 90 → concave groove 86 (return path b) → starting end portion”. 88 ”.

  Further, in the present embodiment described above, the engaging groove 74 as the locking means is set at one place on the upper surface 72B of the track 72. However, the present invention is not limited to this, and as shown in FIG. The engagement groove 74 may be continuously arranged on a straight line. In this way, since the lock is applied in multiple stages according to the opening degree of the lid 16, the opening position of the lid 16 can be adjusted in multiple stages. Therefore, when used for the cup holder 70, there is an advantage that an optimal open state can be obtained for any container size.
