By the way, for example, in the event of a vehicle collision, it is preferable that the vehicle door is kept closed from the viewpoint of occupant protection. However, after a vehicle collision, it is necessary to open the vehicle doors from the inside and outside of the vehicle from the viewpoint of rescuing the occupants.

However, in the conventional vehicle door check device, it is not possible to reliably maintain the closed state of the vehicle door and to release the state at an arbitrary timing.

The present invention has been made in view of such circumstances, and it is possible to more reliably maintain the closed state of the vehicle door and to appropriately open and close the vehicle door depending on the situation. It is an object of the present invention to provide a door check device for a vehicle.

One aspect of the present invention for solving the above problems is in a check plate whose one end is connected to one of the vehicle body and the vehicle door constituting the vehicle, and in a case provided on the other of the vehicle body and the vehicle door. A vehicle door check device including a sliding member that is accommodated and slides on the check plate and an urging means that urges the sliding member toward the check plate. An urging member that abuts on the side of the sliding member opposite to the check plate and is housed in the case to urge the sliding member to the check plate side, and a urging member housed in the case and described above. A vehicle door check device including a holding member that holds the side of the urging member opposite to the sliding member, and a moving device that moves the holding member forward and backward with respect to the check plate. It is in.

Here, a male screw portion is formed on the outer peripheral surface of the holding member, and a female screw portion into which the male screw portion is screwed is formed on the inner peripheral surface of the case, and the moving device holds the holding member. It is preferable to move the member forward and backward with respect to the check plate by rotating the member.

Further, the holding member is provided so as to project toward the check plate side from the contact surface with which the urging member comes into contact, and comes into contact with the sliding member when it is moved forward to the check plate side by the moving device. It is preferable to have a protrusion.

According to the vehicle door check device of the present invention, the vehicle door can be more reliably maintained in the closed state, and the vehicle door can be appropriately opened and closed depending on the situation.

It is a perspective view which shows the schematic structure of the door check device for a vehicle. It is sectional drawing which shows the schematic structure of the door check device for a vehicle. It is sectional drawing which shows the schematic structure of the door check device for a vehicle. It is sectional drawing which shows the schematic structure of the door check device for a vehicle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a vehicle provided with a vehicle door check device according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a schematic configuration of a vehicle door check device. 3 to 5 are views for explaining the urging means constituting the vehicle door check device, and are sectional views showing the internal structure of the case.

As shown in FIG. 1, the vehicle body 1 constituting the vehicle is provided with an opening 2 for getting on and off at a side portion in the vehicle width direction. A vehicle door 4 is attached to the opening 2 by a pair of door hinges 3 arranged side by side in the height direction of the vehicle. The vehicle door 4 is rotatably supported by the door hinge 3 with respect to the vehicle body 1, and the opening 2 can be opened and closed by the vehicle door 4.

The vehicle door 4 can be manually opened and closed, but the vehicle is equipped with an automatic opening / closing mechanism (not shown) for automatically opening and closing the vehicle door 4. As the automatic opening / closing mechanism, a known mechanism may be adopted, and detailed description thereof will be omitted.

A vehicle door check device 10 is attached to the vehicle door 4. As shown in FIGS. 1 to 3, the vehicle door check device 10 includes a check plate 20, a sliding member 30, and an urging means 40.

The check plate 20 is a long plate-shaped member, and its upper and lower surfaces are sliding surfaces 21 and 22 on which the sliding member 30 slides. The sliding surfaces 21 and 22 of the check plate 20 are provided with two convex portions 23 extending in a direction orthogonal to the length direction of the check plate 20, and these convex portions 23 allow the sliding member 30 to be formed. An engaging recess 24 is formed to engage.

The check plate 20 is slidably inserted into the insertion hole 51 of the case 50 fixed to the vehicle door 4, and one end 20a swings around the peripheral edge of the opening 2 of the vehicle body 1. It is connected as possible.

As a result, the check plate 20 is configured to rotate relative to the case 50 while rotating around the end portion 20a in response to the opening / closing operation of the vehicle door 4. That is, the check plate 20 can be slidably moved relative to the case 50 along the longitudinal direction of the check plate 20 in a state of being inserted into the insertion hole 51 of the case 50.

Further, a stopper 60 made of, for example, an elastic member is attached to the other end 20b of the check plate 20. Further, a fixing hole 26 is formed on the outer side of the stopper 60 at the end portion 20b of the check plate 20, and a fixing pin 70 for preventing the stopper 60 from falling off is mounted on the fixing hole 26. When the vehicle door 4 is opened, the stopper 60 comes into contact with the case 50, so that the inertial load associated with the opening operation of the vehicle door 4 can be reduced.

Further, the sliding member 30 and the urging means 40 constituting the vehicle door check device 10 are provided in the case 50 fixed to the vehicle door 4.

The case 50 is a columnar member having an accommodating portion 52 which is an internal space, and is provided with an insertion hole 51 into which the check plate 20 is inserted as described above. The insertion holes 51 are provided on each of the two opposite side surfaces of the case 50, and are formed in a size that allows the check plate 20 to be inserted.

Further, the accommodating portion 52 of the case 50 is formed into a first accommodating portion 52a on the upper side of the check plate 20 and a second accommodating portion 52b on the lower side of the check plate 20 when the check plate 20 is inserted into the insertion hole 51. It is separated. In the case 50, the accommodating portion 52 may be formed in a columnar shape, and the outer shape of the case 50 is not particularly limited.

Each sliding member 30 is housed in a first housing portion 52a and a second housing portion 52b of the case 50, respectively. Each sliding member 30 is accommodated in each of the first accommodating portion 52a and the second accommodating portion 52b so that the small diameter portion 32 faces each of the sliding surfaces 21 and 22 of the check plate 20. The check plate 20 is urged by the urging means 40 described later.

As a result, when the check plate 20 moves relative to the case 50, each sliding member 30 slides on the sliding surfaces 21 and 22 of the check plate 20. When the vehicle door 4 is opened and closed, each sliding member (load plate) 30 slides on the sliding surfaces 21 and 22 of the check plate 20, so that the check plate 20 is loaded. That is, when opening and closing the vehicle door 4, a frictional force is generated between the check plate 20 and the sliding member 30 that move relative to each other. This frictional force becomes a resistance when opening and closing the vehicle door 4. Therefore, the rapid opening / closing movement of the vehicle door 4 can be suppressed.

Here, each sliding member 30 has a large diameter portion 31 having an outer diameter comparable to the inner diameter of the accommodating portion 52 of the case 50, and a large diameter portion sliding on the sliding surfaces 21 and 22 of the check plate 20. It is composed of a small diameter portion 32 having a diameter smaller than 31.

The small diameter portion 32 is formed in a size that is engaged with the engaging recess 24 formed in the check plate 20. When the vehicle door 4 is opened to the fully open position, the small diameter portion 32 of the sliding member 30 engages with the engaging recess 24 of the check plate 20 to hold the vehicle door 4 near the fully open position. It is supposed to be done.

The urging means 40 is provided corresponding to each of the sliding members 30. Each urging means 40 that urges the sliding member 30 includes an urging member 80, a holding member 90, and a moving device 100.

The urging member 80 is a member that abuts on the side of the sliding member 30 opposite to the check plate and is housed in the case 50 to urge the sliding member 30 toward the check plate 20, for example, a coil spring or the like. It is composed of elastic members of.

The holding member 90 is a member housed in the accommodating portion 52 of the case 50 and holds the surface of the urging member 80 opposite to the sliding member 30, and the moving device 100 holds the holding member 90 on the check plate 20. Move forward and backward. That is, the moving device 100 moves the holding member 90 toward the check plate 20 as needed, and moves the holding member 90 toward the side opposite to the check plate 20 as needed.

By moving the holding member 90 forward and backward in this way, the pressing force of the sliding member 30 with respect to the check plate 20 can be adjusted.

In the present embodiment, the holding member 90 has an inner diameter similar to the inner diameter of the case 50, and includes a columnar main body 91 with which the urging member 80 abuts. A male screw portion 92 is formed on the outer peripheral surface of the main body portion 91. On the other hand, on the inner peripheral surface 53 of the case 50, a female screw portion 54 into which the male screw portion 92 of the holding member 90 is screwed is formed. The holding member 90 is housed in the housing portion 52 of the case 50 in a state where the male screw portion 92 is screwed into the female screw portion 54.

Further, the holding member 90 is provided on the urging member 80 side of the main body 91 and includes a small-diameter protruding portion 95 of the main body 91. That is, the protruding portion 95 of the holding member 90 is provided so as to protrude toward the check plate 20 side from the contact surface 91a of the main body portion 91 with which the urging member 80 abuts. Further, the projecting portion 95 is provided so as to project inside the urging member 80 formed of the coil spring.

The protruding portion 95 comes into contact with the sliding member 30 when the holding member 90 is moved forward toward the check plate 20. In other words, the holding member 90 is housed in the housing portion 52 so as to be able to advance to a position where the protruding portion 95 abuts and presses against the sliding member 30.

The moving device 100 is composed of, for example, an electric motor or the like, and its rotating shaft 101 is connected to the holding member 90. In the present embodiment, the moving device 100 is provided on the outside of the case 50, and the rotating shaft 101 extends into the case 50 and is connected to the holding member 90. The moving device 100 moves back and forth with respect to the check plate 20 by rotating the holding member 90.

The moving device 100 is not particularly limited as long as the holding member 90 can be moved back and forth and the moving back and forth can be controlled by control by a control device described later. For example, the moving device 100 may be composed of a hydraulic cylinder or the like. However, in this case, the holding member 90 needs to be housed in the housing portion 52 of the case 50 so as to be linearly movable toward the check plate 20.

Further, the vehicle door check device 10 includes a control unit (control device) 110 that controls the operation of the moving device 100. The control unit 110 includes a CPU, a ROM for storing and storing a control program, a RAM as an operating area for the control program, an EEPROM for holding various data rewritably, an interface unit for interfacing with peripheral circuits, and the like. It is composed.

Although not shown here, the vehicle has a collision sensor that detects a collision, a door handle sensor that detects that the vehicle door 4 has been opened by touching the handle portion of the vehicle door 4, and an obstacle. Various sensors such as an obstacle sensor for detecting the door are provided. Since known sensors may be used as these sensors, detailed description thereof will be omitted.

The control unit 110 acquires various information from these sensors and appropriately controls the mobile device 100 based on the acquired information. That is, the control unit 110 adjusts the pressing force of the sliding member 30 against the check plate 20 by controlling the moving device 100 and moving the holding member 90 forward and backward according to the state of the vehicle.

Specifically, the control unit 110 controls the moving device 100 at a predetermined timing to move the holding member 90 forward toward the check plate 20 and urge the sliding member 30 as shown in FIG. The urging force of the member 80 is increased, and the sliding member 30 is urged by the protruding portion 95 of the holding member 90. As a result, the pressing force of the check plate 20 by the sliding member 30 is increased. That is, the sliding member 30 is crimped to the check plate 20 (crimping state).

In this crimped state, the pressing force of each sliding member 30 against the check plate 20 is relatively strong, so that the relative movement of the check plate 20 with respect to the case 50 is restricted. That is, the opening / closing operation of the vehicle door 4 can be regulated by setting the crimping state.

In particular, when the vehicle door 4 is fully closed, the sliding member 30 (small diameter portion 32) is engaged with the engaging recess 24 of the check plate 20, so the sliding member 30 is checked as described above. By setting the crimping state in which the plate 20 is crimped, the opening / closing operation of the vehicle door 4 can be more reliably regulated.

Further, for example, even when the vehicle door 4 is being opened and the sliding member 30 is not engaged with the engaging recess 24 of the check plate 20, as shown in FIG. 5, the sliding member 30 Is in a crimped state in which the check plate 20 is crimped, so that the relative movement of the check plate 20 is suppressed. Therefore, even during the opening operation of the vehicle door 4, the movement of the vehicle door 4 can be stopped and held by the crimping state.

Further, the control unit 110 controls the moving device 100 at a predetermined timing to move the holding member 90 backward in the direction away from the check plate 20 to reduce the pressing force of the sliding member 30 against the check plate 20 ( (See FIG. 3). That is, the crimping of the sliding member 30 to the check plate 20 is released (non-crimping state).

In this non-crimped state, although the sliding member 30 is urged by the urging member 80, the pressing force of the sliding member 30 against the check plate 20 is weak, so that the relative movement of the check plate 20 with respect to the case 50 is not restricted. .. That is, in the non-crimping state, the vehicle door 4 can be opened and closed.

Switching between the "crimping state" and the "non-crimping contact state" in such a vehicle door check device can be performed at any timing, but it is appropriate according to the vehicle state as shown in Table 1 below. It is preferable to switch.

For example, when the vehicle state is the ignition off, it is preferable to release the crimping state of the sliding member 30 against the check plate 20. This is because it is unlikely that a vehicle collision will occur in the vehicle state where the ignition is off, and it is less necessary to regulate the opening / closing operation of the vehicle door 4.

Further, when the vehicle state is ignition on (stopped) and running, it is preferable to set the crimping state in which the sliding member 30 is crimped to the check plate 20. As a result, since the occupant gets on the vehicle and the vehicle is in a crimped state after the vehicle starts traveling, the vehicle door 4 can be more reliably maintained in the closed state. Therefore, for example, it is possible to prevent the vehicle door 4 from opening due to a collision or the like, and to more reliably protect the occupant.

However, when a vehicle collision is detected, it is preferable to release the crimping of the sliding member 30 to the check plate 20. The control unit 110 detects a collision by a collision sensor provided in the vehicle, and releases the crimping state of the sliding member 30 to the check plate 20 after a predetermined time (for example, several millimeters to several hundred milliseconds) after the collision detection. Is preferable. As a result, the vehicle door 4 can be opened even from the outside, and the occupant can be appropriately protected.

Further, when the vehicle door 4 is manually opened / closed (during the manual opening / closing operation), it is preferable to release the crimping state of the sliding member 30 against the check plate 20. When the control unit 110 detects the opening / closing operation of the vehicle door 4 from the door handle sensor provided in the vehicle, it is preferable that the control unit 110 releases the crimping state of the sliding member 30 with respect to the check plate 20. As a result, the occupant can manually open and close the vehicle door 4 at an arbitrary timing.

Further, when the vehicle door 4 is automatically opened / closed by the automatic opening / closing mechanism provided in the vehicle, it is preferable to release the crimping state of the sliding member 30 against the check plate 20. However, if an obstacle is detected within the moving range of the vehicle door 4 by the obstacle sensor provided in the vehicle during the opening / closing operation of the vehicle door 4, the sliding member 30 is crimped to the check plate 20. It is preferable to put it in a crimped state. As a result, the vehicle door 4 can be appropriately opened and closed by the automatic opening / closing mechanism.

As described above, according to the vehicle door check device 10 according to the present invention, the vehicle door 4 can be more reliably maintained in the closed state, and the vehicle door 4 can be appropriately maintained depending on the situation. It can be opened and closed.

Although one embodiment of the present invention has been described above, the present invention is, of course, not limited to the above-described embodiment.

For example, in the above-described embodiment, the holding member 90 is provided with the protruding portion 95, but the protruding portion 95 may not necessarily be provided. Even with such a configuration, the holding member 90 can be moved to adjust the urging force of the urging member 80 with respect to the sliding member 30 to switch between the "crimping state" and the "non-crimping state". it can.
