Description

  The present invention relates to an electric slide device, and more particularly to an apparatus for sliding a seat provided in a vehicle or the like with an electric motor.

  Conventionally, for example, a configuration described in Patent Document 1 is known as this type of device. The electric slide device described in Patent Document 1 (in the literature, a seat slide device) is configured such that a runner to which a seat is fixed is slidably assembled to a guide rail fixed to a floor of a vehicle. Among these, a pair of electrode strips connected to a battery (power source) mounted on the vehicle is disposed on the guide rail corresponding to the length of the guide rail. On the other hand, the runner is provided with a pair of brushes that slide integrally with the runner in contact with the corresponding electrode strips. In this configuration, a brush that is integrally slid with the runner is brought into contact with the electrode strip disposed on the guide rail, whereby electric power from the battery is supplied to the motor. In the electric slide device having such a power feeding mechanism, the runner slide range can be secured relatively easily by extending the length of the guide rail.

In recent years, for example, in vehicles equipped with three-row seats such as one-box (1BOX) cars, there are various requests for rear seats (second seats, third seats) and for expanding the luggage space. Therefore, even in the case of an electric slide device, it is desirable to allow a wide range of slides to cope with this. Said structure (patent document 1) can be said to be a useful structure in such a point.
Japanese Patent Laid-Open No. 11-11186

However, the conventional configuration has the following problems.
First, disposing an electrode strip on the guide rail increases the number of parts, which increases the cost. In particular, in the case of a long rail type apparatus capable of sliding over a wide range, the electrode band must be disposed corresponding to the length of the long guide rail, so that the assembling work becomes difficult.

  Secondly, there is a problem that the assemblability between the brush and the electrode strip is reduced with the wear of the brush. In the power feeding mechanism as described above, it is required to generate a constant contact force between the brush and the electrode strip in order to ensure a stable conduction state. In this case, for example, a configuration in which the brush is pressed against the electrode strip using a spring or the like is generally considered. However, when the brush deteriorates due to wear, a constant contact force is obtained between the brush and the electrode strip. It becomes difficult. As a result, there is a concern that the assembling property between these two members is lowered, and as a result, an electrical contact failure is caused.

  The present invention has been made in view of such conventional circumstances, and an object of the present invention is to provide an electric slide device including a power feeding mechanism suitable for a long rail type without causing an increase in the number of parts or a decrease in assembling ability. There is to do.

  In order to achieve the above object, the invention according to claim 1 is a fixed rail fixed to a vehicle floor, a runner portion fixed to a seat and slidably assembled to the fixed rail, and the runner portion. A cable that connects the motor unit fixed to the floor and slides the runner unit along the fixed rail based on the rotational force transmitted from the motor unit; A stopper means that engages with a plurality of engaging means formed in the longitudinal direction of the fixed rail and locks the slide of the runner portion to prevent the movement of the seat; the fixed rail includes the stopper When the means is engaged with the engaging means, the stopper means is connected to supply electric power from the power source provided in the vehicle to the seat electrical component via the stopper means. And gist in that a feeding means.

  According to this configuration, the maximum slide amount of the seat can be expanded relatively easily if the length of the fixed rail is increased without increasing the length of the runner portion. It is possible to adopt a configuration suitable for the slide.

  Further, in this configuration, the slide lock / unlock operation of the runner portion is performed by the engaging action of the stopper means of the runner portion and the engaging means of the fixed rail. Here, when the stopper means is engaged with the engaging means, the stopper means is also connected to the power supply means provided on the fixed rail. As a result, the power from the power source is supplied to the seat electrical component via the stopper means when the runner portion is slide-locked. In other words, when the runner portion is sliding, the engagement state between the stopper means and the engagement means is also released, so that the connection between the stopper means and the power supply means is also cut off, so that power is supplied to the sheet electrical component. Also not done. As described above, in this configuration, power can be supplied to the seat electrical component in conjunction with the slide lock / unlock operation of the runner portion. For this reason, a switch or the like for turning on / off the power supply to the seat electrical component is not necessary, and even when the fixed rail is lengthened to correspond to the long rail type, the assembling property between the stopper means and the power supply means ( Electrical connectivity is not reduced. Therefore, in this configuration, it is possible to realize a power feeding mechanism suitable for the long rail type.

  According to a second aspect of the present invention, in the electric slide device according to the first aspect, the engaging means is a lock hole formed in a rail groove of the fixed rail, and the stopper means is formed in the lock hole. The power supply means includes an engaging groove that is engaged with the lock piece when the lock piece is engaged with the lock hole. And

  According to this configuration, the supply of electric power to the sheet electrical component is further engaged with the engagement groove of the power supply means when the lock piece provided on the stopper means is engaged with the lock hole of the fixed rail. Is done by doing. Therefore, it is possible to realize a power feeding mechanism suitable for the long rail type with an extremely simple configuration.

  According to a third aspect of the present invention, in the electric slide device according to the second aspect, the lock piece and the engagement groove are brought into contact with each other when the lock piece and the engagement groove are engaged. Electrodes connected to each other are provided, and the power supply is connected to the electrodes provided in the engagement groove via power supply wiring, and the electrode provided to the lock piece is connected to the sheet via connection wiring. The gist is that electrical components are connected.

  According to this configuration, power is supplied to the sheet electrical component when the lock pieces are engaged with the engagement grooves, and the electrodes provided on the lock pieces are electrically connected to each other. Therefore, it is possible to realize a power feeding mechanism suitable for the long rail type with an extremely simple configuration.

  According to said invention, an electric slide apparatus provided with the electric power feeding mechanism suitable also for a long rail type can be provided, without causing the increase in a number of parts, or the fall of an assembly | attachment property.

  That is, the jack 15 is a seat corresponding to power from a battery (power source) provided in the vehicle 1 through one of the pair of runner portions 21 fixed to each seat. It is provided to supply the sheet electrical equipment.

  Here, the seat electrical component is provided for each seat individually, and functions such as a reclining function and a vertical function are controlled electrically (specifically, an electric motor). Is. By the way, in addition to the above-described functions, the control by the seat electrical component allows a walk-in function for facilitating getting into the third row seat S3, a space-up function for expanding the luggage space, and further, A sheet position memory function for storing the slide stop position (target sheet position) in a memory or the like in advance can be realized.

  Next, a power feeding mechanism to the electric sheet component by the jack 15 and the runner portion 21a will be described with reference to FIG. In addition, although the runner part 21a provided in the fixed rail 12a is demonstrated here as a representative, it is the same also about others.

  As shown in FIG. 6A, the jack 15 is formed with an engagement groove 15a that can be engaged with the lock piece 65a formed in the stopper main body 65, and the lock piece 65a locks the fixed rail 12a. When engaged with the hole 14a, the lock piece 65a is also engaged with the engagement groove 15a of the jack 15.

  As shown in FIG. 6B, an electrode 65 b is provided on the lock piece 65 a of the stopper main body 65. Further, the engagement groove 15a of the jack 15 is provided with electrodes 15b that come into contact with the electrode 65b and are electrically connected to each other when the lock piece 65a is engaged with the engagement groove 15a. Here, the electrode 15 b provided in the engagement groove 15 a of the jack 15 is connected to a battery BT (power source) provided in the vehicle 1 via a power source wiring 71. On the other hand, the stopper main body 65 is provided with a conductive material 65c in contact with the electrode 65b provided on the lock piece 65a and a part thereof, and the conductive material 65c is connected to the sheet via a conductive wire 72 as connection wiring. It is connected to the electrical component 73.

  Accordingly, when the lock piece 65a is engaged with the engagement groove 15a, the electric power from the battery BT is supplied to the sheet electrical component 73 via the power supply wiring 71, the electrode 15b, the electrode 65b, the conductive material 65c, and the conductive wire 72. It is like that. In other words, in the present embodiment, power is supplied to the seat electrical component 73 only when the lock piece 65a is engaged with the lock hole 14a and the engagement groove 15a of the jack 15 and the slide of the runner portion 21a is locked. Is done. Therefore, when the engagement state between the lock piece 65a and the engagement groove 15a is released, the power supply to the sheet electrical component 73 is also automatically cut off.

Next, the stopper function (slide lock / unlock operation) of the electric slide device 11 by the runner portion 21a having the above configuration will be described with reference to FIGS.
7A, the lock piece 65a is engaged with the lock hole 14a and the engagement groove 15a of the jack 15, and the runner portion 21a is locked so as not to be slidable with respect to the fixed rail 12a (hereinafter referred to as “lock state”). It shows the state being done.

  In this state, as described with reference to FIG. 6, the electrode 65b provided on the lock piece 65a and the electrode 15b provided on the engagement groove 15a are in contact with each other (conductive state), and the sheet electrical component 73 Can be supplied with power from the battery BT.

  Now, when the motor unit 24 is driven from this locked state and the cable 27a is moved in the direction of arrow A shown in FIG. 7B, the slider body 45 is similarly slid in the direction of arrow A. At this time, the runner body 31 is not slid and only the slider body 45 is slid with respect to the runner body 31. Then, along with this slide, the fixing pin 64 supported by the spring guide 63 moves along the guide hole 51 from the bottom surface portion 51a to the first inclined surface portion 51b, and the spring guide 63 moves upward against the urging force of the spring 61. Gradually pushed up.

  Next, as shown in FIG. 7C, when the slider body 45 is further slid in the direction of arrow A, the fixing pin 64 moves to the upper end (first upper surface portion 51d) of the first inclined surface portion 51b, and the spring guide 63. Is pushed further upward against the biasing force of the spring 61.

  As a result, the engaged state (locked state) between the lock piece 65a and the lock hole 14a is released, and the runner body 31 (runner portion 21a) is slidable with respect to the fixed rail 12a. At this time, since the engagement state between the lock piece 65a and the jack 15 is also released, the power supply to the seat electrical component 73 is automatically cut off.

  Thereafter, the runner body 31 is slid to the lock hole 14a at the target position T that is a distance X away from the start position S. At this time, in the present embodiment, as shown in FIG. 7D, the runner body 31 is slid to a position (distance X + α) where the lock piece 65a slightly exceeds the lock hole 14a of the target position T.

  After the runner body 31 is slid to the position shown in FIG. 7D, the drive of the motor unit 24 is reversed (the motor rotation direction is reversed in the forward and reverse directions), and then the arrow B shown in FIG. The cable 27a is moved in the direction.

  Here, when the cable 27a is moved in the direction of arrow B, the slider body 45 is similarly slid in the direction of arrow B. At this time, the runner body 31 is not slid and only the slider body 45 is slid with respect to the runner body 31. Then, along with this slide, the fixing pin 64 supported by the spring guide 63 moves along the guide hole 51 from the first upper surface portion 51d to the second inclined surface portion 51f.

  Next, as shown in FIG. 8B, when the slider body 45 is further slid in the direction of the arrow B, the fixing pin 64 is guided downward by the urging force of the spring 61 along the second inclined surface portion 51f. 63 is pushed down. At this time, the runner main body 31 is slid together with the slider main body 45 (distance α) by bringing the fixing pin 64 into contact with the second inclined surface portion 51f.

  As a result, as shown in FIG. 8C, the lock piece 65a is engaged with the lock hole 14a, and the runner body 31 (runner portion 21a) cannot be slid with respect to the fixed rail 12a. That is, the runner portion 21a is locked. At this time, the lock piece 65 a is also engaged with the engagement groove 15 a of the jack 15. Accordingly, it is possible to supply power from the battery BT to the seat electrical component 73.

Thereafter, only the slider main body 45 is slid to the position shown in FIG.
In the present embodiment, after the runner portion 21 is slid to a position (distance X + α) where the lock piece 65a slightly exceeds the lock hole 14a formed at the target seat position, the rotation of the motor portion 24 is reversed. Although the locking operation is performed, this is considered in order to perform the locking operation more reliably. That is, if the fixing pin 64 can be moved downward along the guide hole 51 only by the urging force of the spring 61, the rotation of the motor unit 24 is reversed and locked when the runner unit 21 is slid to the target seat position. An operation may be performed.

As described above, according to the present embodiment, the following effects can be obtained.
(1) A structure in which runner portions 21 (21a to 21f) slidably assembled to fixed rails 12a, 12b, 13a, and 13b are slid by cables 27, 28, and 29 driven by motor portions 24, 25, and 26. did. In this structure, even if the length of the runner portion 21 is not increased, the maximum slide amount can be increased relatively easily by increasing the length of the fixed rails 12a, 12b, 13a, 13b. Thereby, it can be set as the structure suitable also for a long rail type.

  (2) When the lock piece 65a is engaged with the lock hole 14a, the sheet electrical component 73 is supplied with power by engaging the lock piece 65a with the jack 15. In such a structure, the power supply to the seat electrical component 73 can be automatically turned on / off without any switch operation in conjunction with the slide lock / unlock operation of the runner portion 21.

(3) Since the power supply to the seat electrical component 73 is cut when the runner portion 21 slides, the operation of the seat electrical component 73 during the slide can be prevented.
(4) When the runner portion 21 is slide-locked, the lock piece 65a is engaged with the jack 15 together with the lock hole 14a, so that the slide lock effect can be enhanced synergistically.

(5) Since the lock piece 65a constituting the slide lock / unlock mechanism of the runner portion 21 is also used as a power feeding mechanism for the sheet electrical component 73, the number of parts can be reduced.
(6) Since the lock piece 65a and the jack 15 are disconnected when the runner portion 21 slides, their assembling property does not deteriorate with the slide operation of the runner portion 21.

  (7) In the present embodiment, the slide speed of each runner portion 21 can be freely adjusted by changing the reduction ratio for transmitting the rotational force of the motor portions 24, 25, 26 to the cables 27, 28, 29. Is possible.

(8) In the present embodiment, the slide operation and slide lock / unlock operation of the runner portion 21 can be realized by a series of motor drive controls.
(9) In this embodiment, after the runner portion 21 is slid to a distance slightly beyond the target seat position (target seat position + α), the rotation of the motor portions 24, 25, and 26 is reversed forward and backward to perform the locking operation. I did it. In this way, the locking operation (engagement between the lock piece 65a and the lock hole 14a) can be performed more reliably.

  (10) In this embodiment, since the cables 27, 28, and 29 are spiral cables, the connection structure between each runner portion 21 and the motor portions 24, 25, and 26 can be simplified.

  (11) Since the motor parts 24, 25 and 26 are fixedly provided in the floor (floor carpet) of the vehicle 1, the power supply wiring between the motor parts 24, 25 and 26 and the battery BT is made as short as possible. And routing work can be easily performed. Further, with this configuration, the connection wiring is not exposed on the floor with the movement of the seat, so there is no concern about the appearance on the floor being damaged or disconnection.

  (12) In the present embodiment, since the cables 27, 28, and 29 are accommodated in the floor carpet, it is possible to prevent the appearance on the floor from being lowered and the cables 27, 28, and 29 from being disconnected.

In addition, you may implement the said embodiment, changing into the following aspects.
(Modification 1) The engagement means formed in the fixed rails 12a, 12b, 13a, 13b is not limited to the lock hole 14a, and may be a protrusion formed on the inner bottom surface of the rail groove 14, for example. That is, the engaging means may be configured to engage with stopper means (specifically, the lock piece 65a) provided in the runner portion 21 and lock the slide of the runner portion 21.

  (Modification 2) The stopper means provided in the runner portion 21 is not limited to the configuration including the guide portion 32, the slide portion 33, and the stopper portion 34 described in the above-described embodiment (FIG. 5), and other configurations. There may be. For example, the runner body 31 and the guide portion 32 may be formed integrally.

  (Modification 3) The cable 27, 28, 29 is simply a wire cable, and the wire cable is wound or rewound based on the drive of the motor parts 24, 25, 26, so that the runner part 21 is slid. You may make it make it.

  (Modification 4) The shape of the guide hole 51 is not limited to the shape described in the above embodiment, and may be other shapes. That is, as the shape of the guide hole 51, the locking pin 65a is moved up and down in conjunction with the sliding operation of the slider body 45, whereby the engagement operation / disengagement operation between the lock piece 65a and the lock hole 14a is performed. Any shape can be used.

(Modification 5) In the above embodiment, the stopper main body 65 is provided with the electrode 65b and the conductive material 65c. However, only the electrode 65b may be provided.
(Modification 6) The configuration of the stopper main body 65 and the jack 15 (FIG. 6) may be changed to the following configuration as shown in FIG.

  A stopper main body 81 shown in FIG. 9A is provided at the lock hole 14 a of the rail groove 14, the lock piece 82 that can be engaged with the engagement groove 15 a of the jack 15, and the lower end portion of the lock piece 82. The electrode portion 83 is formed so as to be more narrow than the lock piece 82. Although not shown in the figure, the stopper body 81 is connected to each other through the support hole 63b of the spring guide 63 and the fixing pin 64 through the guide hole 51 of the slider body 45, as in the above embodiment. The slider body 45 moves up and down in conjunction with the slide.

  As shown in FIG. 9 (b), the electrode portion 83 is provided with electrodes 83a on both end faces that are sandwiched between the electrodes. The electrode 83a is connected to the sheet electrical component 73 via connection wiring. And with respect to such a stopper main body 81, the engagement groove 15a of the jack 15 is provided with a plate spring 84 as an elastic member that sandwiches the electrode portion 83 and contacts the electrode 83a provided in the electrode portion 83. It has been. The leaf spring 84 is connected to a battery BT (power source) provided in the vehicle 1 via a power supply wiring 71, and supplies power from the battery BT to the seat electrical component 73 through the electrode 83a. It is provided as an electrode.

  That is, when the lock piece 82 of the stopper main body 81 is engaged with the lock hole 14a and the engagement groove 15a, both ends of the electrode portion 83 of the stopper main body 81 are sandwiched by the elastic force of the leaf spring 84. Electric power from the battery BT is supplied to the seat electrical component 73 through a leaf spring 84 that is in contact with the electrode 83 a of the portion 83. Therefore, the configuration of the stopper main body 81 can provide the same effects as those of the above embodiment. Further, in this configuration, since the electrode portion 83 is sandwiched between the plate springs 84 (electrodes) on the jack 15 side at the time of slide lock, the electrical connection between them is more suitably maintained and the sheet electrical component 73 is maintained. It is possible to reliably supply power to the power source.
