Description

  The present invention relates to a vehicle door check device, and more particularly to a vehicle door check device that applies a predetermined operating force when a vehicle door is rotated relative to a vehicle body.

  Some vehicle door check devices are configured to apply different operating forces when the door is rotated in the opening direction and when the door is rotated in the closing direction. For example, Patent Document 1 describes a vehicle door check device in which a first check pattern for opening a door and a second check pattern for closing a door are provided in the middle in the longitudinal direction of the check arm. Yes. The first check pattern and the second check pattern door are check patterns that realize characteristics required when the door is opened and when the door is closed, respectively.

  By the way, in the structure of patent document 1, the 1st check pattern and the 2nd check pattern are provided in one side surface of the check arm, and these are connected with the specific (three places) switching surface. In other words, the first check pattern and the second check pattern can be switched at specific door openings such as full open, half open, and full close of the door, but the first check pattern and the second check pattern can be switched at other door openings. Cannot switch to check pattern. Therefore, it is desired that the opening-side operation force and the closing-direction operation force can be switched according to the opening / closing direction of the door at any opening degree of the door.

JP 2000-203262 A

  In view of the above facts, the present invention has an object to obtain a vehicle door check structure capable of switching between an opening operation force and a closing operation force according to a door opening / closing direction at an arbitrary opening of the door. And

  According to the first aspect of the present invention, the check arm is formed in an elongated shape, and one end side in the longitudinal direction is connected to the vehicle body so as to be relatively rotatable around an axis parallel to the rotation axis of the door hinge. A contact member that provides an operating force for opening and closing the door by contacting the check arm when the door is opened and closed, and the contact member when the door is rotated in the opening direction and when the door is rotated in the closing direction. And a switching unit that switches the surfaces of the check arms having different orientations to contact the contact member by utilizing the fact that the movement directions of the check arms are different.

  In this vehicle door check device, the contact member provided on the vehicle door contacts the side surface of the check arm as the door is opened and closed. When the door is opened and closed in this state, the contact member and the side surface of the check arm move while maintaining the contact state, so that a predetermined operating force is applied to the door opening and closing.

  The movement direction of the check arm relative to the contact member differs between when the door is rotated in the opening direction and when the door is rotated in the closing direction. The switching means uses this to bring the surface of the check arm having a different direction into contact with the contact member when the door is rotated in the opening direction and when the door is rotated in the closing direction. In this way, by completely switching the surface with which the contact member contacts when rotating in the opening direction of the door and the surface with which the contact member contacts when rotating in the closing direction between the surfaces having different orientations, any door With the opening degree, it is possible to switch between the operation force in the opening direction and the operation force in the closing direction according to the opening / closing direction of the door.

  Since the present invention has the above-described configuration, it is possible to switch between an opening operation force and a closing operation force according to the opening / closing direction of the door at any opening of the door.

  Hereinafter, the vehicle door check device 12 according to the first embodiment of the present invention will be described with reference to FIGS. In each drawing, the arrow IN indicates the vehicle interior side direction, the arrow OUT indicates the vehicle exterior direction, and the arrow FR indicates the vehicle front direction.

  As shown in FIG. 2, the vehicle door check device 12 includes a check case 14 and a check arm 16. As shown also in FIG. 1, the check case 14 is fixed to the inner surface of the front end portion of the door inner panel 20 of the side door 18 using a fixing bolt 22 and a nut (not shown).

  The check arm 16 is formed in a long shape, and a mounting hole 24 penetrating in the vertical direction is formed on one end 16A side in the longitudinal direction. As shown in FIG. 1, a mounting pin 30 extending in a vertical direction from a mounting bracket 28 of the vehicle body is inserted into the mounting hole 24. The mounting pin 30 is parallel to the rotation axis Q of the door hinge of the side door 18. As a result, the check arm 16 can be relatively rotated in the lateral direction (arrow R1 direction and the arrow R2 direction opposite thereto) around the mounting pin 30 (on the one end 16A side). Hereinafter, the opening operation of the side door 18 refers to movement in the direction of the arrow R1 that opens the doorway in the vehicle, and the closing operation refers to movement in the direction of the arrow R2 that closes the doorway.

  When the side door 18 is opened, the check arm 16 moves relative to the check case 14 in the direction of arrow S1, and when the side door 18 is closed, the check arm 16 moves in the direction of arrow S2. Move relative. A stopper 26 that prevents the check arm 16 from coming out of the check case 14 is attached to the other end 16B side of the check arm 16.

  In the check arm 16, a joint structure 32 is set near the one end 16A. By providing this joint structure 32, the other end 16 </ b> B side of the joint structure 32 is centered on the rotation center line CL along the longitudinal direction of the check arm 16, and is in the direction of arrow R <b> 3 and the opposite direction of arrow R <b> 4. It can be rotated. In the present embodiment, as the joint structure 32, a support shaft 32A protruding from the other end 16B side is inserted into a shaft hole 32B provided on the one end 16A side, and a retaining ring 32C and a retaining pin 32D are fitted, Rotation in the direction of the arrow R3 and the opposite direction of the arrow R4 is allowed, and a structure is provided that prevents the rotation in the longitudinal direction.

  The check case 14 is formed in a substantially box shape, and an intermediate portion of the check arm 16 is inserted through the opening 34. In the check case 14, a pair of holding blocks 36 </ b> A and 36 </ b> B are provided above and below the opening 34. A pair of pressing walls 38A and 38B extend downward from both sides of the upper holding block 36A in the width direction. As will be described later, the pressing wall 38A presses the inner pressed surface 46A of the check arm 16 in accordance with the opening operation of the side door 18, and the pressing wall 38B is in the check arm according to the closing operation of the side door 18. 16 outer pressed surfaces 46B are pressed. A pair of walls 40A and 40B extend upward from both sides in the width direction of the lower holding block 36B. These walls 40A and 40B are opened and closed by the side door 18. The shape of the lower holding block 36A is determined so as not to contact the inner pressed surface 46A and the outer pressed surface 46B of the check arm 16.

  In each of the holding blocks 36A and 36B, rollers 42A and 42B are rotatably held on the opening 34 side. Further, each of the holding blocks 36A and 36B is applied with a biasing force in a direction in which the holding coils 36A and 36B approach each other by the compression coil spring 44 from the opposite side of the rollers 42A and 42B. Is done.

  As shown in FIGS. 3 and 4, the check arm 16 has an octagonal cross section in a direction perpendicular to the longitudinal direction. This shape will be described in detail. When the side door 18 is not opened and closed, as shown in FIGS. 3A and 4A, the inner pressed surface 46A positioned in the vehicle interior side direction is pressed. The outer pressed surface 46B, which is separated from the wall 38A and is located in the outer side of the passenger compartment, is separated from the pressing wall 38B, and no force (rotational moment) is applied to the check arm 16 from the pressing walls 38A, 38B. .

  Here, when the opening operation of the side door 18 is performed, the inner pressed surface 46A located in the vehicle interior side direction is pressed from the pressing wall 38A as shown in FIG. As a result, a rotational moment M1 in the direction of arrow R3 acts on the check arm 16, and the check arm 16 has a portion on the other end 16B side of the joint structure 32 in the direction of arrow R3 as shown in FIG. Rotate to.

  On the other hand, when the closing operation of the side door 18 is performed, the outer pressed surface 46B positioned in the outer side of the passenger compartment is pressed from the pressing wall 38B as shown in FIG. As a result, a rotational moment M2 in the direction of arrow R4 acts on the check arm 16, and the check arm 16 has a portion on the other end 16B side of the joint structure 32 as shown in FIG. 4C. Rotate in the direction.

  As can be seen from the above, in the first embodiment, the check arm 16 can be partially rotated around the central axis CL by the joint structure 32, and the inner pressed surface 46A or the outer pressed surface 46B can be respectively connected to the pressing wall. The switching means of the present invention is configured by the structure that is pressed by 38A and 38B.

  The inclined surfaces 48A and 48C that face each other in the check arm 16 are parallel to each other, and the inclined surfaces 48B and 48D that face each other are also made parallel to each other. As can be seen from the cross sections shown in FIGS. 3A and 4A, when viewed in a cross section orthogonal to the longitudinal direction of the check arm 16, the inclined surfaces 48A and 48C and the inclined surfaces 48B and 48D are: It has a different orientation. For example, when considering normal vectors V1 and V2 oriented away from the rotation center line C with respect to the inclined surfaces 48A and 48B, in FIG. 3A, the normal vector V1 of the inclined surface 48A is inclined to the right. On the other hand, the normal vector V2 of the inclined surface 48B is inclined to the left.

  As shown in FIG. 3C, when the side door 18 is opened, when the portion on the other end 16B side of the joint structure 32 rotates in the direction of the arrow R3, the inclined surfaces 48A and 48C are moved to the rollers 42A and 42B, respectively. Contact in parallel. As shown in FIG. 4C, when the side door 18 is closed, if the other end 16B side of the joint structure 32 rotates in the direction of the arrow R4, the inclined surfaces 48B and 48D are parallel to the rollers 42A and 42B, respectively. Contact in state.

  As can be seen by comparing FIG. 3C and FIG. 4C, the height H1 of the inclined surfaces 48A and 48C (distance in the normal direction of the inclined surfaces 48A and 48C) is the same as that of the inclined surfaces 48B and 48D. It is longer than the height H2 (distance in the normal direction of the inclined surfaces 48B and 48D). Therefore, the contact pressure of the check arm 16 against the roller 42A is larger in the opening operation of the side door 18 than in the closing operation. However, depending on the position of the check arm 16 in the longitudinal direction, the height H2 of the inclined surfaces 48B and 48D may be longer than the height H1 of the inclined surfaces 48A and 48C.

  As shown in FIG. 2, first inclined check patterns 50 are formed on the inclined surfaces 48 </ b> A and 48 </ b> C so as to change the height H <b> 1 in the longitudinal direction of the check arm 16. In the present embodiment, the first check pattern includes a first raised portion 54 on the side close to the one end 16A and a second raised portion 56 on the side close to the other end 16B, and a first valley between these raised portions. Part 62 is configured. The inclined surfaces 48B and 48D are also formed with a second check pattern 52 that is uneven so as to change the height H2 in the longitudinal direction of the check arm 16. The second check pattern also includes a third raised portion 58 on the side closer to the one end 16A and a fourth raised portion 60 on the side closer to the other end 16B, and a second valley portion 64 is formed between these raised portions. Yes. However, the second check pattern 52 is formed independently of the first check pattern 50 (that is, without affecting each other).

  Next, the operation of the vehicle door check device 12 of this embodiment will be described.

  When the side door 18 is opened, the check case 14 is turned in the direction of arrow R5 shown in FIG. 1, but the check arm 16 tries to keep the state as it is. Thus, since the moving direction of the check case 14 and the moving direction of the check arm 16 are different, the check arm 16 approaches the pressing wall 38A of the holding block 36A as shown by the arrow F1 in FIG. Lateral force is generated in the direction of Then, when the inner pressed surface 46A of the check arm 16 is pressed by the pressing wall 38A, a rotation moment M1 acts on the check arm 16 as shown in FIG. 3B, and the check arm 16 rotates in the direction of the arrow R3.

  As the check arm 16 rotates in the direction of arrow R3, the inclined surfaces 48A and 48C come into contact with the rollers 42A and 42B, respectively. Here, when the side door 18 is further opened, the rollers 42A and 42B rotate and move on the inclined surfaces 48A and 48C while maintaining contact with the inclined surfaces 48A and 48C. Since the first check pattern 50 is formed on the inclined surfaces 48A and 48C, a predetermined operation force determined by the shape of the first check pattern 50 is applied when the side door 18 is opened.

  When the movement of the side door 18 is changed from the opening operation to the closing operation, the relative movement direction of the check arm 16 with respect to the check case 14 is opposite to that during the opening operation at any opening degree of the side door 18. As shown by an arrow F2 in FIG. 4A, a lateral force is generated on the check arm 16 in a direction approaching the pressing wall 38B of the holding block 36A. Then, the outer pressed surface 46B of the check arm 16 is pressed against the pressing wall 38B, and as shown in FIG. 4B, a rotational moment M2 acts on the check arm 16, and the check arm 16 rotates in the direction of arrow R4. To do.

  By this rotation, the inclined surfaces 48B and 48D (surfaces different from those when the side door 18 is opened) come into contact with the rollers 42A and 42B, respectively. Here, when the side door 18 is further closed, the rollers 42A and 42B rotate and move while maintaining contact with the inclined surfaces 48B and 48D. Since the second check pattern 52 is formed on the inclined surfaces 48 </ b> B and 48 </ b> D, a predetermined operation force determined by the shape of the second check pattern 52 is applied when the side door 18 is closed.

  When the movement of the side door 18 is changed from the middle of the closing operation to the opening operation, the inner pressed surface 46A of the check arm 16 is pressed against the pressing wall 38A at any opening degree of the side door 18. Since the arm 16 rotates again in the direction of the arrow R3, the inclined surfaces 48A and 48C come into contact with the rollers 42A and 42B, respectively.

  As can be seen from the above description, in the vehicle door check device 12 according to the present embodiment, the check arm 16 is checked using the fact that the movement directions of the check case 14 and the check arm 16 are different when the side door 18 is opened and closed. 14, the surfaces (inclined surfaces 48A, 48C or inclined surfaces 48B, 48D) having different orientations when the side door 18 is opened and closed are brought into contact with the rollers 42A, 42B. Moreover, the shape (height H1) of the first check pattern 50 formed on the inclined surfaces 48A and 48C and the shape (height H2) of the second check pattern 52 formed on the inclined surfaces 48B and 48D are independent. It has been decided. In this way, the opening operation is performed by switching the surface of the check arm 16 contacting the rollers 42A and 42B independently of the surface on which the shape of the check pattern is determined by the opening operation and the closing operation of the side door 18. It is possible to set a desired operating force independently between the closing operation and the closing operation.

  In addition, in order to switch the surface of the check arm 16 in contact with the rollers 42A and 42B, only the fact that the movement directions of the check case 14 and the check arm 16 are different between the opening operation and the closing operation is used. Therefore, it is possible to switch the surface of the check arm 16 that contacts the rollers 42A and 42B, that is, to switch between the operating force in the opening direction and the operating force in the closing direction at any opening degree of the side door 18.

  FIG. 5 shows a vehicle door check device 82 according to a second embodiment of the present invention. In the second embodiment, the same components and members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Unlike the check arm 16 of the first embodiment, the check arm 86 of the second embodiment is not provided with the joint structure 32, and does not rotate in the directions of the arrows R3 and R4 (both refer to FIG. 2). The cross-sectional shape of the check arm 16 is also rectangular at an arbitrary position in the longitudinal direction, and the inclined surfaces 48A and 48C and the inclined surfaces 48B and 48D are not formed.

  Furthermore, in the check arm 86 of the second embodiment, the first check pattern 50 is formed on the inner pressed surface 46A, and the second check pattern 52 is formed on the outer pressed surface 46B. Similar to the first embodiment, the shape of the first check pattern 50 and the shape of the second check pattern 52 are independently determined.

  Here, as can be seen from the cross section shown in FIG. 6A, the inner pressed surface 46A and the outer pressed surface 46B have different orientations when viewed in a cross section orthogonal to the longitudinal direction of the check arm 86. It has become. For example, when considering normal vectors V3 and V4 in directions away from the rotation center line C with respect to the inner pressed surface 46A and the outer pressed surface 46B, in FIG. 6A, the normal vector V3 of the inclined surface 48A. Is directed to the right, whereas the normal vector V4 of the inclined surface 48B is directed to the left.

  In the check case 84 of the second embodiment, holding blocks 36A and 36B, rollers 42A and 42B, and a compression coil spring 44 are disposed. The roller 42A is a vehicle against the inner pressed surface 46A of the check arm 16. The orientation of the holding blocks 36A and 36B, the rollers 42A and 42B, and the compression coil spring 44 is determined such that the rollers 42B face each other from the interior side direction and the rollers 42B face the outside pressed surface 46B of the check arm 16 from the vehicle compartment outside direction. (Substantially, the holding blocks 36A and 36B, the rollers 42A and 42B, and the compression coil spring 44 in the first embodiment are rotated by 90 degrees).

  When the side door 18 is opened, the roller 42A contacts the inner pressed surface 46A of the check arm 16, and the roller 42B is separated from the outer pressed surface 46B. When the side door 18 is closed, the roller 42B is moved. The spring force of the compression coil spring 44 (or the shape and position of the roller 42A as necessary) is adjusted so that the roller 42A is separated from the inner pressed surface 46A while contacting the outer pressed surface 46B. Yes.

  In the second embodiment configured as described above, when the side door 18 is opened, the check case 14 is turned in the direction of the arrow R5 shown in FIG. 1, and the check arm 16 tries to maintain the state as it is. As shown by an arrow F3 in FIG. 6A, a lateral force in the direction approaching the roller 42A of the check case 84 is generated on the check arm 16, and the inner pressed surface 46A of the check arm 16 contacts the roller 42A. To do. At this time, the outer pressed surface 46B of the check arm 16 is separated from the roller 42B (not in contact).

  When the side door 18 is further opened, the roller 42A rotates while maintaining contact with the inner pressed surface 46A, and moves on the inner pressed surface 46A. Since the first check pattern 50 is formed on the inner pressed surface 46A, a predetermined operation force is applied to the opening operation of the side door 18 although it is determined by the shape of the first check pattern 50.

  When the movement of the side door 18 is changed from the opening operation to the closing operation, the relative movement direction of the check arm 16 with respect to the check case 14 at an arbitrary opening degree of the side door 18 is opposite to that during the opening operation. ), A lateral force in a direction approaching the roller 42B of the check case 14 is generated, as indicated by an arrow F4. At this time, the inner pressed surface 46A of the check arm 16 is separated from the roller 42A (not in contact).

  When the side door 18 is further closed, the roller 42B rotates while maintaining contact with the outer pressed surface 46B and moves on the outer pressed surface 46B. Since the second check pattern 52 is formed on the outer pressed surface 46B, a predetermined operation force determined by the shape of the second check pattern 52 is applied when the side door 18 is closed.

  When the movement of the side door 18 is changed from the closing operation to the opening operation, the inner pressed surface 46A of the check arm 16 contacts the roller 42A at any opening of the side door 18 (the outer pressed surface 46B is It is separated from the roller 42B).

  Thus, in the second embodiment, the switching means of the present invention is configured by pressing the inner pressed surface 46A or the outer pressed surface 46B against the rollers 42A and 42B, respectively.

  Also in the second embodiment, by utilizing the fact that the movement directions of the check case 14 and the check arm 16 are different when the side door 18 is opened and closed, different surfaces (inner side) when the side door 18 is opened and closed. The pressed surface 46A or the outer pressed surface 46B) is brought into contact with the rollers 42A and 42B. The shapes of the first check pattern 50 formed on the inner pressed surface 46A and the second check pattern 52 formed on the outer pressed surface 46B are determined independently. Then, by opening and closing the side door 18, the surface of the check arm 16 that contacts the rollers 42 </ b> A and 42 </ b> B is switched independently by the surface on which the shape of the check pattern is determined. A desired operation force can be set independently of the operation.

  Moreover, in the second embodiment, in order to switch the surface of the check arm 16 that contacts the rollers 42A and 42B, only the movement direction of the check case 14 and the check arm 16 is different between the opening operation and the closing operation. ing. Therefore, it is possible to switch the surface of the check arm 16 that contacts the rollers 42A and 42B, that is, to switch between the operating force in the opening direction and the operating force in the closing direction at any opening degree of the side door 18.

  In the above description, the rollers 42A and 42B are described as the moving members that move while contacting along the first check pattern 50 and the second check pattern 52. However, the moving members of the present invention are not limited to the rollers, and the shoes It may be. Furthermore, it is possible to use a ball as a moving member. For example, in the first embodiment, if the shapes of the inclined surface 48A and the inclined surface 48B are determined so that the ball can contact both the inclined surface 48A and the inclined surface 48B, the balls are used instead of the rollers 42A. It is possible. Similarly, if the shapes of the inclined surface 48C and the inclined surface 48D are determined so that the ball can come into contact with both the inclined surface 48C and the inclined surface 48D, it is possible to use a ball instead of the roller 42B.

  Moreover, although the example which applied the vehicle door check structure of this invention to the side door 18 of the motor vehicle above was given, it is also possible to apply not only to the side door 18 but also to a back door, for example.
