TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sliding door device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a slide door device provided in a vehicle includes a fully open lock device and a fully closed lock device between a vehicle body and a slide door, so that the slide door is maintained at a fully open position or a fully closed position. It is composed. Therefore, for example, if the sliding door is in the fully closed position, the sliding door does not accidentally move in the door opening direction even when the vehicle body is tilted low toward the opening direction of the sliding door. . Similarly, when the sliding door is in the fully open position, the sliding door does not accidentally move in the closing direction even when the vehicle body is tilted low toward the closing direction of the sliding door.
[0003]
In addition, in recent slide door devices, various devices have been devised to improve usability, such as providing a so-called intermediate stopper mechanism. The intermediate stopper mechanism includes, for example, an intermediate striker provided on the vehicle body side, and a stopper member called a pole provided on the slide door side so as to be swingable. When the opening degree of the window hole is equal to or less than the threshold value, the stopper member is held at the retracted position against the urging force of the spring by engaging the hook member, and gives any support to the slide of the slide door. Absent. On the other hand, when the opening degree of the window hole exceeds the threshold value, the engagement state by the hook member is released, and the stopper member protrudes toward the vehicle body by the urging force of the spring. As a result, when the sliding door is slid in the door opening direction, the protruding stopper member comes into contact with the intermediate striker, and further sliding is prevented. Therefore, even if the user puts his / her face or hand through the window hole, it is possible to prevent a situation in which the user is caught between the vehicle and the vehicle body (for example, see Patent Document 1).
[0004]

[Problems to be solved by the invention]
By the way, when opening and closing the slide door, the user of the vehicle does not always stop the slide door at the fully open position or the fully closed position. In particular, for vehicles with a large overall length, such as a one-box type, the amount of slide required to move the slide door from the fully closed position to the fully open position is large. A situation in which the door is slid very slightly and stopped (hereinafter, simply referred to as a half-open state) can often occur.
[0006]
When the slide door is placed in a half-open state as described above, even if the vehicle is provided with the above-described fully-open lock device and fully-closed lock device, these will not function. Therefore, when the vehicle is inclined along the opening direction of the sliding door, there is a possibility that the sliding door may run by gravity.
[0007]
Here, when closing the slide door, the weather strip provided on the entire circumference between the slide door and the vehicle body functions as a sufficiently large cushioning material. For this reason, even if the slide door reaches the fully closed position at a high speed, no loud noise is generated.
[0008]
However, when the sliding door is opened, the weather strip does not function as a cushioning member, and a member called a fully open stopper collides with a receiving surface on the vehicle body side to reach the fully opened position. For this reason, even if a cushioning material such as rubber is provided between the fully-open stopper member and the receiving surface of the vehicle body, if the sliding door having a high speed reaches the fully-open position, a loud noise is generated. Is difficult to suppress. Further, in the case where the intermediate stopper mechanism is provided as in Patent Literature 1 described above, it is difficult to secure sufficient strength for the stopper member, which not only generates noise but also damages the intermediate stopper mechanism. There is even a risk of doing so.
[0009]
The present invention has been made in view of the above circumstances, and has as its object to provide a slide door device that can reliably prevent generation of noise even when the slide door is stopped in a half-open state.
[0010]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a slide door device slidably disposed with respect to a vehicle body, and a door speed detecting means for detecting a speed of at least when the slide door slides in an opening direction. And a braking means for braking the slide door when the detection result of the door speed detecting means exceeds a preset threshold value.
[0011]
According to a second aspect of the present invention, there is provided a sliding door device according to the first aspect, wherein a door position detecting means for detecting a position of the sliding door with respect to the vehicle body, and an intermediate position in which the sliding door is preset from a fully closed position. The slide that protrudes from one of the vehicle body and the slide door toward the other when operated in the state between and contacts the other, thereby restricting the slide of the slide door with respect to the vehicle body in the door opening direction. Regulating means, wherein the braking means applies braking to the slide door after the slide regulating means is actuated and before the slide of the slide door is regulated.

More specifically, a drum 32 is provided on a drive shaft of a slide motor 31 as an actuator, and a door closing wire 33 for extending the slide door 10 forward and a door opening wire 34 for extending the slide door 10 rearward. By connecting the drum 32 and the support frame 122 with each other, the forward / reverse rotation of the slide motor 31 is transmitted to the support frame 122 through the wires 33 and 34, so that the slide door 10 is opened or closed. It is configured to slide.
[0018]
The fully closed holding means 40f, 40r are for maintaining the slide door 10 at the fully closed position, and between the front edge of the slide door 10 and the vehicle body 1, and between the rear edge of the slide door 10 and the vehicle body. It is provided at two places before and after between the two. The fully open holding means 50 is for maintaining the slide door 10 at the fully open position, and is provided between the support frame 122 of the lower guide means 12 and the vehicle body 1, for example, as shown in FIG. In this embodiment, the strikers 51 are provided on the vehicle body 1 side and the latches 52 are provided on the slide door 10 side as the fully closed holding means 40f, 40r and the fully opened holding means 50, as shown in FIG.

Of course, even when the door handle 16 provided inside and outside the slide door 10 is operated, the engagement state between the striker 51 and the latch 52 of the fully open holding means 50 and the fully closed holding means 40f, 40r can be released.
[0019]
As shown in FIGS. 1 and 2, the slide door 10 is provided with a window hole opening detecting means 60, and a door detecting means 70, a slide restricting means 80, and a braking means are provided between the sliding door 10 and the vehicle body 1. Means 90 are provided.
[0020]
The window opening detecting means 60 detects the opening of the window 14 due to the opening and closing movement of the window glass 20. As shown in FIG. 1, in the present embodiment, as the window opening detection means 60, the rotation amount of the window motor 15a is determined based on an output pulse from a rotary encoder (not shown) provided in the window motor 15a. In addition, an apparatus that detects the opening degree of the window hole 14 by calculating the rotation direction is applied. The detection result of the window opening detection means 60 is given to the opening / closing control section 100 described later.
[0021]
The door detecting means 70 is for detecting the position and speed of the sliding door 10 with respect to the vehicle body 1, as shown in FIG. In this embodiment, the rotation amount and the rotation direction of the slide motor 31 are calculated based on an output pulse from a rotary encoder (not shown) provided in the slide motor 31 as the door detection unit 70, The one that detects the position and speed of the slide door 10 with respect to the vehicle body 1 is applied. The detection result of the door detecting means 70 is given to the opening / closing control unit 100 described later.
[0022]
The slide restricting means 80 is for restricting the slide of the slide door 10 relative to the vehicle body 1 in the opening direction when the slide door 10 is operated before reaching the fully open position. In the present embodiment, the stopper member 81 is provided on the support frame 122 of the lower guide unit 12 so as to be able to advance and retreat, while the abutment portion 82 is provided on the vehicle body 1 as the slide regulating unit 80. As shown in FIGS. 2 (a) and 2 (c), the slide restricting means 80 holds the stopper member 81 at a position where the stopper member 81 has been retracted and moved in a non-operating state, and does not hinder the slide of the slide door 10 at all. There is no. On the other hand, as shown in FIG. 2B, when the slide restricting means 80 operates, the stopper member 81 is held in a state of being advanced toward the vehicle body 1 by an actuator (not shown), and the slide door 10 is moved in the door opening direction. When the sliding door 10 is slid, the stopper member 81 comes into contact with the contact portion 82 of the vehicle body 1, and the sliding of the sliding door 10 is prevented. The position where the stopper member 81 contacts the contact portion 82 is before the slide door 10 reaches the fully open position, and as shown in FIG. 1B, the front side frame of the opened window hole 14 and the vehicle. The main body 1 is set such that a predetermined gap can be secured between the main body 1 and the C pillar 3 (hereinafter, simply referred to as an intermediate position).
[0023]
The braking means 90 is for applying a brake to the slide door 10. In the present embodiment, a connection is made to the drum 32 of the automatic sliding means 30 via the electromagnetic clutch 91, and when the electromagnetic clutch 91 is in a connected state, a load is applied to the rotation of the drum 32, and the door closing wire 33 and the door opening A device that applies braking to the slide door 10 through the wire 34 is applied.
[0024]
FIG. 3 is a block diagram illustrating an open / close control system of the slide door device in the above-described four-wheeled vehicle. The opening / closing control unit 100 shown in FIG. 3 is for controlling the operation of the slide regulating unit 80 and the braking unit 90 based on the detection result of the window opening detection unit 60 and the detection result of the door detection unit 70. Hereinafter, the processing content of the opening / closing control unit 100 will be described with reference to the flowchart shown in FIG.
[0025]
First, the opening / closing control unit 100 constantly monitors the detection result of the window hole opening detecting means 60, and determines whether or not the opening of the window hole 14 exceeds a preset threshold value (step S100). It is preferable that the threshold value used as a criterion is a value as small as possible.
[0026]
When the opening of the window hole 14 detected by the window hole detecting unit 60 is 150 mm or less, the opening / closing control unit 100 holds the slide regulating unit 80 in a non-operating state (step S101). When the slide restricting means 80 is in a non-operating state, the stopper member 81 is held at the position where the stopper member 81 has been retracted and moved as described above. 82 do not contact each other. Therefore, as shown in FIG. 2A, even when the slide door 10 is in the fully closed position, the striker 51 of the fully closed holding means 40f, 40r engages with the latch 52 by operating a door switch or the like. If the state is released, the slide door 10 can be slid to the fully open position without any trouble. As a result, as shown in FIG. 2 (c), the boarding / alighting opening 2 of the vehicle body 1 is greatly opened, so that passengers can easily get in and out and load and unload luggage.
[0027]
During this time, the opening / closing control unit 100 monitors the position of the sliding door 10 through the door detecting means 70 (step S102), and detects the sliding door 10 through the door detecting means 70 until the sliding door 10 reaches the fully open position. It is detected whether or not the speed exceeds a predetermined threshold (step S103).
[0028]
If the speed of the slide door 10 is equal to or lower than the threshold, the procedure returns to step S102 without performing the processing described below. On the other hand, if the speed of the slide door 10 exceeds the threshold, a process for operating the braking means 90 is performed until the speed of the slide door 10 becomes equal to or lower than the threshold (step S104). Therefore, for example, even when the vehicle is placed in a half-open state under a situation where the vehicle is inclined low toward the opening direction of the slide door 10, the slide door 10 travels at a high speed and reaches the fully open position as it is. There is no fear and no loud noise is generated.
[0029]
If it is detected in step S102 that the slide door 10 has reached the fully opened position, the current process is terminated.
[0030]
On the other hand, when the opening degree of the window hole 14 exceeds 150 mm in step S100, the opening / closing control unit 100 switches the slide regulating unit 80 to the operating state (step S105). When the slide restricting means 80 is activated, the stopper member 81 is held in a state of moving forward toward the vehicle body 1 as described above, so that the slide door 10 is slid in the door opening direction. Then, the stopper member 81 comes into contact with the contact portion 82 of the vehicle body 1, and as shown in FIG. 2B, between the front side frame of the opened window hole 14 and the C pillar 3 of the vehicle body 1. The slide of the slide door 10 is prevented at an intermediate position where a predetermined gap is secured. As a result, even if there is a foreign matter that passes through the opening area of the window hole 14, it is possible to prevent the foreign matter from being caught between the vehicle body 1 and the foreign matter.
[0031]
During this time, the opening / closing control unit 100 monitors the position of the sliding door 10 through the door detecting means 70 (step S106), and detects the sliding door 10 through the door detecting means 70 until the sliding door 10 reaches the middle position. Then, it is detected whether or not the speed exceeds a predetermined threshold (step S107).
[0032]
If the speed of the slide door 10 is equal to or lower than the threshold, the procedure returns to step S106 without performing the processing described below. On the other hand, if the speed of the slide door 10 exceeds the threshold, a process of operating the braking means 90 is performed until the speed of the slide door 10 becomes equal to or lower than the threshold (step S108). Therefore, for example, even when the vehicle is placed in a half-open state under a situation where the vehicle is inclined low toward the opening direction of the slide door 10, the slide door 10 travels at a high speed and reaches the halfway position as it is. There is no danger, and no loud noise is generated and the slide restricting means 80 is not damaged.
[0033]
If it is detected in step S106 that the slide door 10 has reached the halfway position, that is, if the slide restricting means 80 has detected that the slide door 10 has stopped at the halfway position, the current process ends.
[0034]
Hereinafter, the opening / closing control unit 100 repeatedly executes the above-described processing, and activates the slide restricting unit 80 when the opening degree of the window hole 14 exceeds a preset threshold value, thereby opening the sliding door 10 in the door opening direction. Start to regulate slides. Therefore, even if the face or the hand is put out through the window hole 14, the situation of being caught between the vehicle body 1 can be prevented, and the usability can be improved. Moreover, when the sliding door 10 travels at a high speed by itself, the braking means 90 operates to reduce this, so that even when the sliding door 10 is stopped in a half-open state, noise may occur or the sliding may occur. It is possible to reliably prevent a situation in which the regulating means 80 is damaged.
[0035]
In the above-described embodiment, the slide door device for opening and closing the entry / exit opening 2 provided at a position substantially at the center of the side of the vehicle body 1 called a one-box type is exemplified. It is not necessary to be a side surface, and the present invention can of course be applied to a device that opens and closes an opening provided in another type of vehicle body. In addition, as an opening / closing member, the window glass 20 which opens and closes by rotating the window motor 15a by operating a regulator switch is illustrated, but it is not necessarily required to be a glass member and need not be operated by a motor. In short, any other device that opens and closes the window hole 14 of the slide door 10 may be used, and the opening and closing operation direction is not limited to the vertical direction. Further, as the window hole opening detecting means 60 and the door detecting means 70, those detecting each based on an output pulse from a rotary encoder (not shown) are applied. Further, the specific configuration is not necessarily limited to the embodiment.
[0036]
Further, in the above-described embodiment, the slide door device provided with the slide restricting means 80 is exemplified, but the slide door device need not always be provided. In the embodiment, the threshold value for operating the slide door device provided with the slide restricting means 80 is set to 150 mm in the embodiment, but is not necessarily set to 150 mm and may be set to an arbitrary value. For example, if this threshold value is set to 0 mm, it is possible to more reliably prevent foreign matter from being caught.
[0037]
【The invention's effect】
As described above, according to the sliding door device of the first aspect of the present invention, when the sliding speed of the sliding door exceeds a preset threshold, the braking means is operated to reduce the braking speed. Also, even when the slide door is stopped in a half-open state, it is possible to reliably prevent the occurrence of noise.
[0038]
Further, according to the slide door device according to the second aspect of the present invention, the brake is applied before the slide of the slide door is restricted after the slide restricting means is operated, so that the slide door is opened halfway. Even when the slide stop means is stopped, it is possible to reliably prevent a situation where noise is generated in the slide restraint means and a situation where the slide restraint means is damaged.
