  Hereinafter, an embodiment of a door opening adjustment device will be described. Hereinafter, the upper direction and the lower direction in the height direction of the vehicle are referred to as “upper” and “lower”, respectively. Further, the inside in the width direction of the vehicle heading toward the inside of the vehicle interior is referred to as “vehicle inside”, and the outside in the width direction of the vehicle toward the outside of the vehicle interior is referred to as “vehicle outside”. In particular, the width direction of the vehicle with respect to the door (the vehicle inner side, the vehicle outer side) refers to that considered to be closed.

  As shown in FIG. 1, an opening 2 for getting on and off is formed in a side portion of a body 1 of the vehicle, and an edge 2 a in front of the opening 2 is arranged in parallel in the height direction of the vehicle. A door 4 is rotatably connected by a pair of door hinges 3. The door 4 is opened and closed by rotating in one direction and the other direction around the door hinge 3.

  In addition, a base end portion of a substantially long check link 11 made of, for example, a molding material obtained by integrating resin with a metal rod is connected to the edge portion 2a so as to be rotatable in accordance with the opening / closing direction of the door 4. The door 4 is fastened with a door check 16 through which a tip portion of the check link 11 entering the door 4 is movably inserted in the longitudinal direction. The check link 11 and the door check 16 constitute the door check mechanism 10.

  The check link 11 moves relative to the door check 16 (door 4) in the longitudinal direction while swinging about the base end portion in accordance with the opening / closing operation of the door 4. That is, as shown in FIGS. 2 (a) and 2 (b), the edge 2a is formed with a substantially flat mounting surface 5 that is recessed toward the inside of the vehicle, and the mounting surface 5 is made of, for example, a metal plate. A bracket 12 is fastened. On the other hand, the door 4 has a door outer panel 6 that extends so as to face the outside of the vehicle, and a box-shaped door inner panel 7 that is disposed on the inside of the vehicle. The edge of the door outer panel 6 and the opening of the door inner panel 7 are provided. A substantially sealed internal space is formed by joining the ends. Note that the door 4 is opened and closed by rotating about the shaft 3 a of each door hinge 3.

  The base end portion of the check link 11 is connected to the bracket 12 so as to be rotatable around an axis extending in the vehicle height direction, and the front end portion of the check link 11 is opposed to the rear of the mounting surface 5. It enters the door 4 through the wall portion 8 of the door inner panel 7. On the other hand, the door check 16 is fastened to the wall portion 8 in the door 4, and the tip end portion of the check link 11 entering the door 4 is inserted. As described above, the check link 11 moves relative to the door check 16 in the longitudinal direction while swinging about the base end portion in accordance with the opening / closing operation of the door 4. Then, as shown by a change from FIG. 2A to FIG. 2B, for example, when the door 4 is opened, the check link 11 is retracted from the door 4 through the door check 16 or the like. Conversely, when the door 4 is closed, the check link 11 enters the door 4 through the door check 16 or the like. That is, the relative position of the check link 11 to the door check 16 uniquely corresponds to the opening / closing position (opening) of the door 4. Specifically, the opening degree decreases as the length L of the check link 11 protruding from the door check 16 into the door 4 increases, and conversely, the opening degree increases as the length L decreases.

  As shown in FIG. 3, the check link 11 has a plurality of upper and lower pairs of valleys 13 and 14 formed at intervals in the longitudinal direction, and the door check 16 has one of the pair of valleys 13 and 14. A pair of rollers (not shown in the figure) are incorporated that slightly restrict the movement of the check link 11 in the longitudinal direction by sandwiching 14. Therefore, when the movement of the check link 11 in the longitudinal direction is slightly restricted by the door check 16, the door 4 is slightly held at the corresponding opening / closing position (opening).

  Further, as shown in FIG. 4, a pair of protruding piece-like stopper portions 15 that extend to both sides in the width direction of the vehicle are formed at the tip of the check link 11. These stopper portions 15 contact the door check 16 when the check link 11 tries to retract from the door 4 through the door check 16 or the like with the opening operation of the door 4, so The opening operation is restricted (see FIG. 2B). The open / close position (opening degree) of the door 4 at this time corresponds to the fully open position.

  A guide member 20 made of, for example, a metal plate is attached to the wall portion 8 of the door 4. The guide member 20 includes a substantially band-shaped mounting wall 21 extending in the height direction of the vehicle, and a pair of support walls extending rearward from both ends (the vehicle outer end and the vehicle inner end) of the mounting wall 21 in the vehicle width direction. 22 and has a substantially U-shape opening rearward. The guide member 20 is fastened (so-called joint fastening) to the wall portion 8 together with the door check 16 in a state where the mounting wall 21 is sandwiched between the wall portion 8 and the door check 16.

  Each support wall 22 is formed with a substantially rectangular guide hole 23 extending in the height direction of the vehicle. In addition, the guide member 20 has a top plate portion 24 that connects the upper edges of the tip portions of the support walls 22. A substantially circular insertion hole 25 that opens in the height direction of the vehicle is formed at the center of the top plate portion 24.

  As shown in FIG. 5, an adjustment member 30 made of, for example, a metal plate is supported on the guide member 20 while being sandwiched between the support walls 22. The adjustment member 30 has a pair of adjustment walls 31 that spread along the inner wall surfaces of the support walls 22. The distance in the vehicle width direction between the two adjustment walls 31 is basically set to be larger than the distance between the tips of the stopper portions 15 of the check link 11. Each adjustment wall 31 is formed in a substantially L shape in which the rearward extension length of the upper end portion 32 is longer than the rearward extension length of the lower end portion 33. Both adjustment walls 31 have a substantially L-shaped extending piece 34 that extends further rearward from the lower end of the upper end portion 32 and bends in the vehicle width direction from the rear end. The rear end surface of each extending piece 34 forms a first stepped portion 34a. Moreover, both the adjustment walls 31 have the substantially L-shaped extension piece 35 which bends in the width direction of the vehicle which extends further back from the vehicle height direction intermediate part of the lower end part 33, and approaches mutually from a rear end. A rear end surface of each extending piece 35 forms a second stepped portion 35a. That is, the distance in the vehicle width direction between the two adjustment walls 31 is reduced at the positions of the step portions 34a and 35a. The distance in the direction between both stepped portions 34 a and the distance in the direction between both stepped portions 35 a are equal to each other, and are set smaller than the distance between the tips of both stopper portions 15 of the check link 11. It goes without saying that the second stepped portion 35a is positioned forward and below the first stepped portion 34a.

  Incidentally, the distance in the vehicle width direction between the two adjustment walls 31 is set to be larger than the distance between the tips of the stopper portions 15 of the check link 11 above the step portion 34a and below the step portion 35a. The adjustment member 30 forms an upper escape portion 30a by a space sandwiched between the adjustment walls 31 above the step portion 34a and below the top plate portion 38. Further, the adjustment member 30 forms a lower relief portion 30b by a space sandwiched between the adjustment walls 31 below the step portion 35a. In addition, the lower part of the level | step-difference part 35a which forms the lower side relief part 30b shall include the range which extended both the adjustment walls 31 below. That is, the lower escape portion 30 b includes a range below the both adjustment walls 31.

  Each adjustment wall 31 is formed with a pair of substantially circular mounting holes 36 and 37 spaced in the height direction of the vehicle. The mounting holes 36 and 37 are arranged in front of the extending pieces 34 and 35 (steps 34 a and 35 a), respectively, and their inner diameters are set to be equal to the opening width of the guide hole 23 in the short direction. Yes. Moreover, the adjustment member 30 has the top-plate part 38 which connects the upper edges of both the adjustment walls 31 (upper end part 32). A substantially circular insertion hole 39 that opens in the height direction of the vehicle is formed at the center of the top plate portion 38.

  The adjustment member 30 is supported by the guide member 20 movably in the vehicle height direction by a pair of guide pins 41 and 42 as a pair of guide protrusions arranged in parallel in the vehicle height direction on each adjustment wall 31. ing. That is, the guide pins 41 and 42 have substantially disc-shaped head portions 41 a and 42 a having a diameter larger than the opening width in the short direction of the guide hole 23 and are equivalent to the opening width in the short direction of the guide hole 23. And substantially cylindrical insertion portions 41b and 42b protruding from the center of the heads 41a and 42a. The adjustment member 30 is supported by the guide member 20 by inserting and fastening the insertion portions 41b and 42b of the guide pins 41 and 42 inserted through the guide holes 23 from the outside of the support walls 22 into the mounting holes 36 and 37, respectively. Is done. At this time, the adjustment member 30 moves in the height direction of the vehicle with respect to the guide member 20 in a range from a position where the insertion portion 41 b contacts the upper end of the guide hole 23 to a position where the insertion portion 42 b contacts the lower end of the guide hole 23. Is possible. That is, the lower end (termination, first termination) of the movable range of the adjustment member 30 with respect to the guide member 20 is determined by the position where the insertion portion 42b contacts the lower end (termination) of the guide hole 23. Further, the upper end (termination, second termination) of the movable range of the adjustment member 30 with respect to the guide member 20 is determined by the position where the insertion portion 41 b contacts the upper end (termination) of the guide hole 23.

  The insertion hole 39 of the adjustment member 30 is set so as to be substantially concentric with the insertion hole 25 of the guide member 20 and face the vehicle in the height direction. And between the top plate parts 24 and 38, the compression spring 43 as a biasing member which consists of coil springs, for example is interposed. Both ends of the compression spring 43 are in pressure contact with the peripheral portions of the insertion holes 25 and 39, respectively, and always urge the adjustment member 30 downward against the guide member 20.

  The lower end 45 of the cable 44 that basically extends in the height direction of the vehicle is sequentially inserted into the insertion holes 25 and 39 together with the compression spring 43. The terminal 45 is secured to the top plate portion 38 below the insertion hole 39. The terminal on the upper side of the cable 44 is connected to an adjustment dial 46 exposed in the passenger compartment (for example, on the door trim), and the vehicle between the top plate portion 24 and the terminal 45 is operated by turning the adjustment dial 46. The distance in the height direction is configured to be extendable. In other words, the adjustment member 30 urged downward by the compression spring 43 reduces the distance between the top plate portion 24 and the terminal 45 with respect to the guide member 20 as the adjustment dial 46 rotates in one direction. As the distance between the top plate portion 24 and the terminal 45 extends as the adjustment dial 46 rotates in the reverse direction, the adjustment dial 46 descends with respect to the guide member 20. At this time, the movement of the adjusting member 30 is guided by sliding the guide pins 41 and 42 in the respective guide holes 23. The adjustment dial 46 only needs to be equipped with a known mechanism that winds and unwinds the cable 44 in accordance with, for example, the turning operation.

Next, the operation of this embodiment will be described.
First, as shown in FIG. 6A, the position of the adjustment member 30 is adjusted by rotating the adjustment dial 46, and the extension piece 34 (first step Assume that a step 34a) is arranged. In this state, the opening operation of the door 4 is restricted when both stopper portions 15 of the check link 11 retracted from the inside of the door 4 come into contact with the first stepped portion 34a. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 is L1, and the opening operation of the door 4 is restricted by the first opening.

  Further, as shown in FIG. 6B, the position of the adjustment member 30 is adjusted by the turning operation of the adjustment dial 46, and the extension piece 35 (second step of the second step) is moved on the forward movement trajectory of the check link 11. It is assumed that the stepped portion 35a) is arranged. In this state, the opening operation of the door 4 is restricted when the stopper portions 15 of the check link 11 retracted from the inside of the door 4 come into contact with the second stepped portion 35a. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 is L2 (<L1), and the opening operation of the door 4 is performed at a second opening larger than the first opening. Be regulated.

  Further, as shown in FIG. 6C, the position of the adjustment member 30 is adjusted by rotating the adjustment dial 46, and the adjustment member 30 (strictly, the extended piece 35) is disposed above the door check 16. Suppose that In this state, the opening operation of the door 4 is restricted when both stopper portions 15 of the check link 11 retracted from the door 4 come into contact with the door check 16. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 becomes zero, and the opening operation of the door 4 is restricted at the fully open position.

  Moreover, as shown to Fig.7 (a), when the insertion part 41b is located in the lower end of the guide hole 23, both the stopper parts 15 are set so that it may be arrange | positioned at the upper side escape part 30a. That is, in this state, both stopper portions 15 are released from the adjustment member 30 by the upper escape portion 30a, thereby eliminating the restriction on the opening operation of the door 4 due to the contact of both the stopper portions 15 and the adjustment member 30. Can do. Therefore, for example, when the cable 44 is disconnected due to a vehicle collision or the like, the adjustment member 30 biased by the compression spring 43 moves until the insertion portion 41b reaches the lower end of the guide hole 23, thereby opening the door 4. Regulations can be resolved automatically.

  Furthermore, as shown in FIG. 7B, when the insertion portion 41b is positioned at the upper end of the guide hole 23, both stopper portions 15 are set to be disposed in the lower escape portion 30b. That is, in this state, both stopper portions 15 are released from the adjustment member 30 by the lower relief portion 30b, thereby eliminating the restriction on the opening operation of the door 4 due to the contact of both the stopper portions 15 and the adjustment member 30. be able to. Accordingly, when the adjustment member 30 moves against the biasing force of the compression spring 43 until the cable 44 bends due to the action of the load F caused by a vehicle collision or the like and the insertion portion 41b reaches the upper end of the guide hole 23, the door 4 The restriction of the opening operation can be automatically canceled.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In this embodiment, the opening operation accompanying the rotation of the door 4 in one direction is such that each stopper portion 15 of the check link 11 abuts one of the step portions 34 a and 35 a of the adjustment member 30. It is regulated by. Then, by the operation (winding / unwinding) of the cable 44, the adjustment member 30 is moved while moving the guide pins 41, 42 along the respective guide holes 23, and the step portions 34a, 35a with which the respective stopper portions 15 abut. The maximum opening of the door 4 can be adjusted by changing. In this case, the adjustment member 30 with which both stopper portions 15 abut is that guide pins 41 and 42 (insertion portions 41b and 42b) are inserted into the respective guide holes 23 of the guide member 20 fixed in the door 4. Further, the opening of the door beyond the adjusted opening can be more firmly regulated. In particular, when the guide pin 42 is positioned at the lower end of the guide hole 23, the stopper portion 15 is released from the adjustment member 30 by the upper escape portion 30 a, so that the door 4 is brought into contact with the stopper portion 15 and the adjustment member 30. The restriction of opening operation can be eliminated. Therefore, for example, when the cable 44 is cut due to a vehicle collision or aging deterioration, the adjusting member 30 biased by the compression spring 43 moves until the guide pin 42 reaches the lower end of the guide hole 23, thereby The restriction of the opening operation can be automatically canceled. And the door 4 can be more reliably opened to the fully open position.

  (2) In the present embodiment, when the guide pin 41 is positioned at the upper end of the guide hole 23, the stopper portion 15 is released from the adjustment member 30 by the lower escape portion 30b, so that the stopper portion 15 and the adjustment member 30 are released. The restriction of the opening operation of the door 4 due to the contact can be eliminated. Therefore, when the adjustment member 30 moves against the biasing force of the compression spring 43 until the cable 44 is bent due to, for example, a vehicle collision (particularly a side collision) and the guide pin 41 reaches the upper end of the guide hole 23, The restriction of the opening operation can be automatically canceled. And the door 4 can be more reliably opened to the fully open position.

  (3) In the present embodiment, the adjustment member 30 can sandwich the check link 11 in the vehicle width direction (a parallel direction different from the moving direction of the check link 11 and the extending direction of the guide hole 23). In addition, a pair of adjustment walls 31 provided with step portions 34a and 35a and guide pins 41 and 42 are provided. The guide member 20 has a pair of support walls 22 in which guide holes 23 are formed so as to sandwich the adjustment member 30 in the width direction of the vehicle. Further, the check link 11 has a pair of stopper portions 15 so as to be able to contact each of the step portions 34a and 35a of the both adjustment walls 31. Accordingly, the opening operation of the door 4 is restricted by the stoppers 15 of the check link 11 coming into contact with either of the step portions 34a and 35a of the adjusting walls 31. And the adjustment member 30 which both stopper parts 15 contact | abut is over the adjusted opening degree by the guide pins 41 and 42 being inserted in each guide hole 23 in the state pinched | interposed into both the support walls 22. FIG. Thus, it is possible to more firmly regulate the opening of the door 4. In this case, the check link 11 further stabilizes the posture of the check link 11 by causing the stopper portions 15 to abut on both adjustment walls 31 (steps 34a, 35a) that sandwich the check link 11 in the vehicle width direction. Can be In addition, the guide member 20 has the guide pins 41 and 42 inserted into the guide holes 23 of the both support walls 22 that sandwich the adjustment member 30 in the width direction of the vehicle, so that both the stopper portions 15 are connected to the adjustment member 30. The input load can be supported more firmly in a state where both ends are supported.

  (4) In this embodiment, the compression spring 43 is interposed between the top plate portion 24 of the guide member 20 and the top plate portion 38 of the adjustment member 30, so that the adjustment member 30 caused by, for example, vehicle vibration can be prevented. Shaking can be suppressed. Further, for example, even if the vehicle posture is tilted, the posture of the adjustment member 30 can be held more firmly.

  (5) In this embodiment, when the guide pin 41 is positioned at the upper end of the guide hole 23, the stopper portion 15 is positioned below the adjustment member 30. For this reason, even if the cable 44 is not sufficiently bent, the door is required if at least the stopper portion 15 is positioned below both the extending pieces 35, that is, if it is positioned in the lower escape portion 30b. The restriction on the opening operation 4 can be eliminated.

  (6) In the present embodiment, the guide pins 41 and 42 are positioned at the end of the guide hole 23 to determine the end of the adjustment member 30 in the movable range with respect to the guide member 20. There is no need to add a separate member, and the number of parts can be reduced.

In addition, you may change the said embodiment as follows.
In the embodiment, when the guide pin 41 is located at the upper end of the guide hole 23, the stopper portion 15 is located below the adjustment member 30, but at least the stopper portion 15 is more than both the extending pieces 35. What is necessary is just to be located below.

  In the embodiment, a lever or the like may be employed instead of the adjustment dial 46 as long as the cable 44 can be operated to extend and contract. In addition, when the cable 44 includes an actuator that electrically expands and contracts, an operation switch that operates driving of the actuator may be employed. In this case, the installation position of the operation switch is not limited to the door trim, and may be an arbitrary part of the vehicle such as a dashboard. In addition, when an acquisition member (for example, a distance sensor, a camera, or the like) that acquires a separation distance between the door 4 and an obstacle outside the door 4 is provided, the driving of the actuator is controlled by a control device such as a microcomputer according to the acquired separation distance. May be.

  -In the said embodiment, if both the adjustment walls 31 of the adjustment member 30 are located inside the both stopper parts 15 of the check link 11, the extended piece (34, 35) is made non-bent in the width direction of the vehicle. Also good. In this case, the rear end surface of the non-bending extended piece forms a stepped portion. Further, the distance in the width direction of the vehicle between the two adjustment walls 31 is enlarged above the upper step portion to form an upper relief portion, and is enlarged below the lower step portion to lower the lower relief portion.
