Description

  The present invention relates to a console box that opens and closes a console lid by driving a motor.

  A console box (floor console) installed between a driver's seat and a passenger seat of a vehicle is provided with a console body having an article storage portion that opens in a vehicle compartment, and the opening of the article storage portion. A console lid for releasably closing the section. In order to enhance the convenience of the console lid opening / closing operation, a console box equipped with an electric lid opening / closing mechanism using a driving force of a motor has been put into practical use. As a console box having an electric lid opening / closing mechanism, for example, a console box having the configuration shown in FIGS. 12 and 13 has been proposed.

  In the console box shown in FIG. 12, the console lid 12 is pivotally supported with respect to the console main body 10 via a support member 80, and the console lid 12 is opened and closed by a motor 82 installed on the console main body 10. A lid opening / closing mechanism is provided. That is, the pinion 83 is fixed to the output shaft of the motor 82, and the spur gear 84 fixed to the rotation center of the support member 80 is engaged with the pinion 83. Therefore, the console lid 12 converts the rotation of the motor 82 into the swing of the support member 80 by a gear reduction mechanism including the pinion 83 and the spur gear 84, and closes the article storage portion 11 (two-dot chain line in FIG. 12). And a fully open position (indicated by a one-dot chain line in FIG. 12) where the article storage unit 11 is opened.

  In the console box shown in FIG. 13, the console lid 12 is pivotally supported with respect to the console main body 10 via a hinge 88, and the lid for opening and closing the console lid 12 by the motor 82 installed on the console main body 10. An opening / closing mechanism is provided. That is, the pinion 83 is fixed to the output shaft of the motor 82, and the spur gear 84 is fixed to the pivot shaft of the hinge 88 described above. The pinion 83 and the spur gear 84 mesh with the intermediate gear 86, respectively. Yes. Accordingly, the console lid 12 transmits the rotation of the motor 82 by the gear reduction mechanism including the pinion 83, the spur gear 84, and the intermediate gear 86, and the fully closed position (indicated by a two-dot chain line in FIG. 13). ) And a fully open position (indicated by a one-dot chain line in FIG. 13) in which the article storage unit 11 is opened.

Each of the console boxes shown in FIGS. 12 and 13 has a configuration in which the motor 82 is disposed in the vicinity of the lower end portion of the support member 80 that is the rotation center of the console lid 12 or in the vicinity of the hinge 88. A lid opening / closing mechanism including a gear reduction mechanism is made compact. Here, when the motor 82 is disposed in the vicinity of the rotation center of the console lid 12, since the output shaft of the motor 82 and the rotation center of the console lid 12 are close, the opening / closing operation of the console lid 12 is performed according to the so-called “lion principle”. Therefore, it is necessary to use a high torque type motor that requires a large torque. However, the high torque type motor has a drawback that it is large and heavy, and has a large drive sound. Further, since the motor itself is expensive, the manufacturing cost of the console box increases. Therefore, in recent years, console lids disclosed in, for example, Patent Literature 1 and Patent Literature 2 have been proposed in order to solve the above-described problems.

The outer member 16 is formed by combining a plurality of component parts 16A, 16B, and 16C according to regulations such as design and molding technology. Among these, the component part 16C is an ornament member that also serves as a decoration.

  The console lid 12 is a molded member that is injection-molded from a synthetic resin material such as polypropylene (PP). The console lid 12 is injection-molded from a lid outer member 30 having a shape and size that can be aligned with a lid placement site on the upper surface of the console body 10 and a synthetic resin material such as polypropylene. And a lid inner member 32 mounted inside. On the outer surface of the lid outer member 30, an elastic member 34 having appropriate elasticity and a skin material 36 covering the elastic member 34 are disposed. Accordingly, the console lid 12 faces the fully closed position and is held by the lid storage portion 24, so that the elastic member 34 and the skin material 36 face outward, and function as an armrest for a passenger using the front seat. It is like that.

  As described above, the console lid 12 is attached to the inner member 18 of the console body 10 by the lid support mechanism 40 disposed in the rear space 26 of the console body 10 and is in the fully closed position (FIG. 1, FIG. Stable posture displacement is possible between the fully open position (FIGS. 3 and 6). The lid support mechanism 40 is disposed on a swing support member 46 whose one end is pivotally supported by the console body 10 and whose other end is pivotally supported by the console lid 12, and both side walls 18 A and 18 A of the inner member 18.

A second support shaft through hole 48 that allows insertion of the second support shaft is formed. In addition, mounting base portions 46C for fixing a bracket 62 (described later) project from the portions of the support lever portions 46A adjacent to the second support shaft through holes 48, respectively.

  Each guide rail 31 extends linearly with a required length from the rear end of the lid inner member 32 forward on the left and right side wall surfaces of the lid inner member 32 of the console lid 12. In other words, each guide rail 31 is moved from the position where the support pin 50 faces when the console lid 12 faces the fully closed position (FIG. 1) to the guide rail 31 when the console lid 12 faces the fully opened position (FIG. 6). The length is set such that the support pin 50 can relatively move to the position where the support pin 50 faces.

  Therefore, in the console lid 12, the swing support member 46 in the lid support mechanism 40 rotates with respect to the console body 10 and the console lid 12, and each support pin 50 in the lid support mechanism 40 extends along each guide rail 31. By relatively sliding, the opening / closing operation is stably performed while the posture is defined between the fully closed position (FIGS. 1 and 3) and the fully open position (FIGS. 2 and 6). When the console lid 12 is in the fully closed position, as shown in FIG. 3, the swing support member 46 is inclined rearward and upward at an angle of about 60 degrees from the horizontal, and each support pin 50 is positioned at the rear end of the guide rail 31, and the console lid 12 is held in alignment with the lid storage portion 24.

  Next, an electric lid opening / closing mechanism 60 that opens and closes the console lid 12 between the fully open position and the fully closed position described above will be described. In the console box FC of the embodiment, as shown in FIGS. 3 to 7, one set of lid opening / closing mechanism 60 is provided on each of the left and right support lever portions 46 </ b> A of the swing support member 46. Since these lid opening / closing mechanisms 60 and 60 are symmetrical and have the same basic configuration, the same members and the same parts will be described with the same reference numerals.

  Each lid opening / closing mechanism 60 is provided with a motor 64 and a pinion 68 rotated by the motor 64 in the vicinity of the second support shaft 44 in the swing support member 46, and on the inner member 18 side of the console body 10. An arc-shaped rack 70 having a required radius centered on one support shaft 42 is provided, and a pinion 68 is engaged with the arc-shaped rack 70. The motor 64 and the pinion 68 are connected via a worm gear 65, and the rotation of the motor 64 is transmitted to the pinion 68 via the worm gear 65. That is, each lid opening / closing mechanism 60 includes a motor 64, a worm gear 65 composed of a worm 65 a fixed to the output shaft of the motor 64 and a worm wheel 65 b fixed to one end of the rotating shaft 66, and the other end of the rotating shaft 66. And the arcuate rack 70 provided on the console main body 10.

  As shown in FIGS. 4 and 7, the motor 64 and the rotating shaft 66 are attached in advance to a bracket 62 attached to the mounting base portion 46 </ b> C of the swing support member 46, and the bracket 62 is assembled to the mounting base portion 46 </ b> C. Is arranged on the swing support member 46. The bracket 62 is formed by bending, for example, a metal plate material. The bracket 62A has a substantially rectangular horizontal plate portion 62A, and a vertical plate that is bent at a substantially right angle from both end edges of the horizontal plate portion 62A and faces each other. It is a member which consists of plate part 62B, 62C, and exhibits the substantially U shape opened to the 2nd spindle 44 side. The horizontal plate portion 62A functions as a mounting portion for the motor 64, and an insertion hole that allows insertion of the output shaft of the motor 64 is provided. The vertical plate portions 62B and 62C function as support portions for rotatably supporting the rotary shaft 66 described above, and the vertical plate portions positioned on the side where the rotary shaft 66 extends outward. 62C also functions as a mounting portion for the mounting base portion 46C of the support lever portion 46A.

  As shown in FIGS. 3 and 4, the motor 64 is fixed to the horizontal plate portion 62A with the output shaft inserted through the horizontal plate portion 62A of the bracket 62, and the console lid 12 faces the fully closed position. The posture is substantially vertical. The motor 64 is, for example, a publicly known DC motor that is generally commercially available, and a small, lightweight, low-cost motor having a rated torque of about 5 to 8 mN · m is preferably used. That is, in the lid opening / closing mechanism 60 of the embodiment, as will be described later, the reduction ratio (ratio between the rotation speed of the motor 64 and the rotation speed of the swing support member 46) is set to about 1/500. Even with a small motor having a torque of about 5 to 8 mN · m, the console lid 12 can be opened and closed smoothly without difficulty. As shown in FIGS. 1 to 3, the motor 64 is electrically connected to an open / close operation switch 39 provided on the outer member 16 facing the front side of the lid storage portion 24 in the console body 10. Based on the on / off control by 39, rotation control in both forward and reverse directions at a constant speed is performed.

  The opening / closing operation switch 39 is a three-pole changeover switch connected to a power source (not shown), and can be switched to an opening / closing stop position, an opening operation position, and a closing operation position, and a fingertip operation by an occupant is not performed. Is held at the open / close stop position so that the motor 64 is not energized. When the opening / closing operation switch 39 is switched to the opening operation position, the motor 64 rotates in the forward rotation direction, and when the opening / closing operation switch 39 is switched to the closing operation position, the motor 64 moves in the reverse rotation direction. It is set to rotate. The opening / closing operation switch 39 is configured to automatically return to the opening / closing stop position when the operation to the opening operation position or the closing operation position is released. As for the opening / closing operation switch 39, various types such as a rocker type, a lever type, a bush type, a slide type or a toggle type are appropriately selected in consideration of the mounting position on the console body 10 and the convenience of passengers. The

  As shown in FIGS. 4 and 7, the rotation shaft 66 is inserted into a shaft support hole formed in both the vertical plate portions 62 </ b> B and 62 </ b> C of the bracket 62, and extends in a direction orthogonal to the output shaft of the motor 64. And it is rotatably supported in the state extended to the one vertical plate part 62C side. Accordingly, when the bracket 62 is attached to the mounting base portion 46C of the support lever portion 46A, the rotary shaft 66 penetrates the support lever portion 46A horizontally and protrudes to the side, with the tip facing the arc-shaped rack 70 side. become. Prior to mounting the bracket 62 on the mounting base 46C, the above-described pinion 68 is fixed to the tip of the rotating shaft 66 that faces the arc-shaped rack 70, and then the bracket 62 is mounted on the mounting base 46C. The pinion 68 comes to a position where it engages with the arc-shaped rack 70.

  A worm gear 65 comprising a worm 65a fixed to the output shaft of the motor 64 and a worm wheel 65b fixed to the rotary shaft 66 between the vertical plate portions 62B and 62C of the bracket 62 is a predetermined standard based on the JIS standard. As is well known, it has a characteristic that a large reduction ratio can be obtained in one stage. In the embodiment, the reduction ratio is set to about 1/50. The worm 65a is molded from stainless steel, steel, or the like, and the worm wheel 65b is molded from a self-lubricating synthetic resin such as polyacetal so that smooth meshing is always achieved within the period of use. It has become. Further, the worm gear 65 of the embodiment is a type in which rotation transmission from the worm wheel 65b to the worm 65a is impossible, and since the worm 65a does not rotate even if the worm wheel 65b is rotated, the worm wheel 65b does not rotate. Being regulated.

  The pinion 68 fixed to the rotating shaft 66 is provided with a gear of a predetermined module based on the JIS standard, and is fixed to the rotating shaft 66 so as not to rotate. Further, as described above, the arc-shaped rack 70 is formed in an arc shape with the first support shaft 42 as the center, and is a gear of the same module as the pinion 68. Here, as is well known, the reduction ratio of the pinion 68 and the arcuate rack 70 by the gear train is determined by the ratio between the number of teeth of the pinion 68 and the number of teeth of the arcuate rack 70. It can be calculated by a radius ratio, a diameter ratio, or an outer periphery ratio with the rack 70. Accordingly, in the lid opening / closing mechanism 60 according to the embodiment, the radius ratio between the pinion 68 and the arc-shaped rack 70 is set to approximately 1:10 (see FIG. 3), and thus the pinion 68 and the arc-shaped rack 70 are included. The reduction ratio of the gear train is about 1/10. The pinion 68 is molded from a self-lubricating synthetic resin such as polyacetal, and the arc-shaped rack 70 formed integrally with the inner member 18 is made of the same polypropylene (PP) as the inner member 18. It is made of a material, so that smooth meshing is always achieved within the period of use.

  Therefore, in the lid opening / closing mechanism 60 of the embodiment, the primary deceleration is performed between the motor 64 and the pinion 68 by the worm gear 65 described above, and the secondary deceleration is performed between the pinion 68 and the arc-shaped rack 70. It has become so. As described above, since the primary reduction ratio is about 1/50 and the secondary reduction ratio is about 1/10, the overall reduction ratio of the lid opening / closing mechanism 60 is about 1/500. That is, in the lid opening / closing mechanism 60 of the embodiment, the reduction ratio is set large by the gear train composed of the worm gear 65, the pinion 68 and the arc-shaped rack 70, so that the torque required for opening / closing the console lid 12 is small. As described above, the motor 64 having a rated torque of about 5 to 8 mN · m can be suitably used as a drive source.

  For example, when the output shaft of the motor 64 rotates at a constant speed of 5000 rpm, if the overall reduction ratio of the lid opening / closing mechanism 60 is set to 1/500, the swing support member centered on the first support shaft 42 Since the rotation speed of 46 is 10 rpm, the swing support member 46 makes one rotation in 6 seconds. In the console box FC of the embodiment, the console lid 12 is moved between the fully closed position and the fully open position by swinging (turning) the swing support member 46 by about 120 degrees (1/3 rotation). Since the opening / closing operation is set, the opening operation and the closing operation of the console lid 12 are completed in about 2 seconds.

  The motor 64 is provided with a limit mechanism (not shown). In the limit mechanism, when the console lid 12 faces from the fully open position to the fully closed position, or from the fully closed position to the fully open position (that is, the support pins 50 and 50 reach the front end position or the rear end position of the guide rails 31 and 31). In this case, the motor 64 is stopped regardless of the operation state of the open / close operation switch 39, and the motor 64 is protected from overload. The limit mechanism does not rotate the motor 64 in the forward rotation direction when the open / close operation switch 39 is operated to the open operation position while the console lid 12 faces the fully open position, and the console lid 12 reaches the fully closed position. It is set so that the motor 64 is not rotated in the reverse direction when the opening / closing operation switch 39 is operated to the closing operation position in the open state.

(Operation of Example)
Next, the operation of the console box according to the embodiment will be described.

  When the console lid 12 faces the fully closed position and is stored in the lid storage portion 24 (FIGS. 1 and 3), when the open / close operation switch 39 is operated to the open operation position, the motor 64 is driven at a constant speed in the forward rotation direction. Rotation is controlled by. Then, the rotation of the output shaft of the motor 64 is transmitted to the rotation shaft 66 through the worm gear 65, and the pinion 68 stopped at the upper end position of the arc-shaped rack 70 is rotated counterclockwise in FIG. Become. Accordingly, since the pinion 68 moves downward along the arc-shaped rack 70, the swing support member 46 swings clockwise around the first support shaft 42 in FIG. As a result, the console lid 12 connected to the swing support member 46 is drawn into the rear space 26 from the rear end side, and the pinion 68 reaches the lower end position of the arc-shaped rack 70 as shown in FIG. By moving, the console lid 12 faces the fully open position. In the console lid 12, the swing support member 46 constituting the lid support mechanism 40 swings about the first support shaft 42, and the support pin 50 is relatively moved from the rear end to the front end of the guide rail 31. By sliding, the posture during the opening operation from the fully closed position to the fully opened position is stably maintained.

  When the console lid 12 reaches the fully open position, the limit mechanism described above operates, so that the rotation of the motor 64 is stopped even if the operation on the open / close operation switch 39 is continued, and the motor 64 is overloaded. Is prevented.

  When the console lid 12 faces the fully open position and is accommodated in the rear space 26 (FIGS. 2 and 6), when the open / close operation switch 39 is operated to the closing operation position, the motor 64 is set in the reverse rotation direction. The rotation is controlled at high speed. The rotation of the output shaft of the motor 64 is transmitted to the rotating shaft 66 via the worm gear 65, and the pinion 68 stopped at the lower end position of the arc-shaped rack 70 rotates clockwise in FIG. Accordingly, since the pinion 68 moves upward along the arc-shaped rack 70, the swing support member 46 swings counterclockwise around the first support shaft 42 in FIG. As a result, the console lid 12 connected to the swing support member 46 is pushed outward from the front end side with respect to the rear space 26, and the pinion 68 is attached to the arc-shaped rack 70 as shown in FIG. 3. By moving to the upper end position, the console lid 12 reaches the fully closed position. In the console lid 12, the swing support member 46 constituting the lid support mechanism 40 swings about the first support shaft 42, and the support pin 50 is relatively moved from the front end to the rear end of the guide rail 31. , The posture during the closing operation from the fully open position to the fully closed position is stably maintained.

  When the console lid 12 reaches the fully closed position, the limit mechanism described above operates, so that the rotation of the motor 64 is stopped even if the operation on the opening / closing operation switch 39 is continued, and the motor 64 is overloaded. A state is prevented.

  The opening / closing operation switch 39 is energized to the motor 64 only when the opening / closing operation switch 39 is operated to the opening operation position or the closing operation position, and automatically returns to the opening / closing stop position when the switch operation is released. Thus, the power supply to the motor 64 is released. Therefore, for example, during the opening / closing operation, when the operation of the opening / closing operation switch 39 is released when the console lid 12 is displaced in the state of FIG. 5, the opening / closing operation switch 39 automatically returns to the opening / closing stop position and the motor 64. Since the rotation of the console lid 12 stops, the console lid 12 stops at the position shown in FIG. Moreover, as described above, the worm gear 65 cannot transmit the rotation from the worm wheel 65b to the worm 65a. Therefore, even if the front end portion of the console lid 12 is moved upward or downward, the console lid 12 The posture displacement is restricted, and the console lid 12 is held in the posture shown in FIG.

  Therefore, according to the console box FC of the embodiment, the following operational effects can be obtained. First, the motor 64 used for the opening / closing operation of the console lid 12 is installed at a position far away from the center of rotation of the swing support member 46 that supports the console lid 12, and the rotation fulcrum of the console lid 12 and the motor 64 can increase the distance between the power point and the gear ratio (reduction ratio) between the pinion 68 and the arc-shaped rack 70 is set large, and the torque required for the opening / closing operation of the console lid is reduced. 64 can be miniaturized. Therefore, since a small, light and low-priced motor can be used as the motor 64, the console box FC can be reduced in weight and manufacturing cost can be reduced. Further, since the motor 64 is disposed at a position away from the article storage section 11 of the console body 10, there is no inconvenience that the internal volume of the article storage section 11 is reduced.

  In the console box FC of the embodiment, a worm gear 65 capable of setting a large reduction ratio is disposed between the motor 64 and the pinion 68, and the rotation of the motor 64 is transmitted to the pinion 68 via the worm gear 65. Due to the structure, the overall reduction ratio of the lid opening / closing mechanism 60 is set large. Therefore, a smaller, lighter and less expensive motor can be used as the motor 64 used for the opening / closing operation of the console lid 12, and further weight reduction and manufacturing cost reduction of the console box FC can be expected.

  Further, in the console box FC of the embodiment, when the console lid 12 is opened and closed by the lid opening and closing mechanism 60, the support pin 50 of the lid support mechanism 40 disposed on the console body 10 is provided with the guide rail 31 provided on the console lid 12. Therefore, the console lid 12 can be stably opened and closed. Further, since the console lid 12 can be appropriately stopped at an arbitrary position during the opening / closing operation by the switch operation on the opening / closing operation switch 39, the console lid 12 can be moved to the fully opened position without opening the console lid 12. Articles can be taken in and out. Further, by using the worm gear 65 as a speed reduction mechanism, the console lid 12 stopped at an arbitrary position is held at that position unless the motor 64 is rotated based on the switch operation of the opening / closing operation switch 39. The posture is not unnecessarily displaced to the position or the fully open position.

(First change example)
In the console box FC according to the above-described embodiment, the worm gear 65 and the pinion 68 are directly connected by a single rotating shaft 66. However, when the reduction ratio of the lid opening / closing mechanism 60 is set to be larger, For example, as shown in FIG. 8, a spur gear train may be interposed between the worm gear 65 and the pinion 68. That is, the worm wheel 65b of the worm gear 65 is fixed to the first rotating shaft 66a, the pinion 68 is fixed to the second rotating shaft 66b, the first intermediate gear 67 is fixed to the first rotating shaft 66a, and the second rotating shaft is fixed. The second intermediate gear 69 that meshes with the first intermediate gear 67 may be fixed to the 66b. Accordingly, since the gear ratio of the spur gear train composed of the first intermediate gear 67 and the second intermediate gear 69 is further reduced between the worm gear 65 and the pinion 68, the overall reduction ratio of the lid opening / closing mechanism 60 is further increased. It can be set large, and a small, light and low-priced motor can be used, and further weight reduction and manufacturing cost reduction of the console box FC can be expected.

(Second change example)
As the motor 64, for example, as shown in FIG. 9, a motor (gear motor) of a type having a gear reduction mechanism 90 such as a planetary gear mechanism may be used. When such a gear motor is used as the motor 64, since the output shaft of the motor 64 is decelerated, for example, as shown in FIGS. 9 and 10, the output shaft of the motor 64 and the rotary shaft 66 are directly connected. It is possible. Even if the lid opening / closing mechanism 60 is configured in this way, the same operational effects as those of the console box FC of the above-described embodiment can be obtained. In the case where the motor 64 and the rotary shaft 66 are directly connected, it is possible to install the motor 64 in a state where it is accommodated in the support lever portion 46A of the swing support member 46, as shown in FIG. The bracket can be omitted.

(Third change example)
In the above-described embodiment, one set of the lid opening / closing mechanism 60 is provided on each of the left and right sides of the swing support member 46 and the motor 64 is provided for each lid opening / closing mechanism 60. When the opening / closing operation of the console lid 12 can be performed by a single motor 64, the lid opening / closing mechanisms 60, 60 may be operated by a single motor 64 as shown in FIG. That is, in the configuration of FIG. 11, the rotating shaft 66 in both lid opening / closing mechanisms 60 and 60 is made common. Further, when the console lid 12 can be opened and closed by one motor 64, the lid opening and closing mechanism 60 is disposed only on either the left side or the right side of the swing support member 46, although illustration is omitted. You may do it.
