(Problems to be solved by the invention)
The door check device generally includes a check rod and a case fixed in the vehicle door. One end of the check rod is swingably connected to the vehicle body and extends into the vehicle door. A stopper member is provided at the other end of the check bar. The case is formed with an insertion hole for inserting a check rod in the vehicle door. When the vehicle door is opened, the check rod moves relative to the vehicle door and the case while being inserted through the case so as to be pulled out from the vehicle door. When the opening / closing position of the vehicle door reaches the fully open position, the stopper member provided at the other end of the check bar engages with the case. Such engagement restricts further opening operation of the vehicle door from the fully open position.

  As the stopper member, a so-called T-shaped stopper is generally adopted. Such a stopper member is formed so that the length in the direction perpendicular to the longitudinal direction of the check rod is larger than the diameter of the insertion hole of the case. When the vehicle door is opened to the fully open position, the stopper member engages with the wall surface (contact surface) around the insertion hole of the case.

  The vehicle door is swingably connected to the vehicle body by a hinge shaft or the like, and opens and closes an opening provided in the vehicle body by swinging about the hinge shaft with respect to the vehicle body. Therefore, when the vehicle door is strongly opened so that the opening / closing position of the vehicle door is further opened from the fully open position to the overopen position, the stopper member engaged with the case is centered on the swing center position of the vehicle door. Try to rotate. Therefore, stress strongly acts on a portion (outer portion) on the side far from the swing center of the vehicle door in the contact surface of the case engaged with the stopper. As a result, the outer portion is greatly deformed. When the contact surface of the case is greatly deformed locally in this way, there is a possibility that problems such as deformation of parts in the case and large change of the fully open position of the vehicle door may occur.

  Accordingly, an object of the present invention is to provide a door check device configured to prevent local deformation of a case even when a vehicle door is opened to an overopen position.

(Means for solving the problem)
According to the present invention, one end of the vehicle body is swingably connected to the vehicle body, and is extended into a vehicle door that is swingably connected to the vehicle body to open and close the vehicle body opening. A check rod that is relatively moved in the vehicle door so that it is pulled out from the vehicle door and an insertion hole that is fixed in the vehicle door and through which the check rod extending into the vehicle door is inserted A case, a sliding member disposed in the case and providing a sliding resistance force to the check rod in the case, and provided at the other end of the check rod. When the vehicle door is opened to the fully open position, A stopper member having an engagement surface that can engage with a contact surface that is a wall surface around the insertion hole, and when the vehicle door is opened to the fully open position, the contact state between the engagement surface and the contact surface is , Swing of the vehicle door out of the engagement surface The inner part, which is the part closer to the center, abuts against the contact surface, and a one-sided contact state is formed in which a gap is formed between the outer part, which is the far side part, and the contact surface. A door check device in which the contact state between the engagement surface and the contact surface is brought into a contact state in which both the inner portion and the outer portion are in contact with the contact surface when opened from the position to the overopen position. provide. In this case, when the vehicle door is opened to the fully open position, the engagement surface is engaged with the contact surface inclined, and when the vehicle door is opened to the overopen position, the engagement surface is brought to the contact surface. It is good to be comprised so that it may engage in a parallel state.

  According to the present invention, when the open / close position of the vehicle door is the fully open position, the inner portion of the engagement surface of the stopper member that is closer to the vehicle door swing center position is in contact with the engagement surface on the far side. A gap is formed between the outer portion and the engaging surface. For example, when the open / close position of the vehicle door is the fully open position, the engagement surface is engaged with the contact surface inclined to the contact surface. That is, the stopper member and the case are brought into a single-contact state when the open / close position of the vehicle door is the fully open position. When the vehicle door is opened to the overopen position, both the outer part and the inner part of the engaging surface of the stopper member are brought into contact with the engaging surface. For example, when the open / close position of the vehicle door is the overopen position, the engagement surface is engaged in a state parallel to the contact surface. For this reason, when the opening / closing position of the vehicle door is the over-open position, the contact area between the stopper member and the case is increased, and the engagement surface is uniformly in contact with the entire contact surface. The stress acting on is dispersed. Therefore, it can prevent that a case deform | transforms large locally. As a result, a large deformation of a member (for example, a sliding member) in the case can be prevented, and a large change in the fully opened position is prevented by reducing the deformation amount.

  The sliding member may be configured so as to sandwich both side surfaces of the check bar in a plane perpendicular to the longitudinal direction of the check bar. And it is good for the check rod to be formed with a taper portion in which the length between both side surfaces increases from one end to the other end. In this case, the tapered portion may be formed from an intermediate portion in the longitudinal direction of the check rod to the other end.

  According to this, when the vehicle door is opened with a strong force, the sliding member slides on the tapered portion of the check rod, so that the sliding resistance acting on the check rod as the vehicle door approaches the fully open position. Power is increased. Therefore, the collision speed between the stopper member and the case when the vehicle door reaches the fully open position can be reduced. As a result, the vehicle door can be effectively prevented from reaching the overopen position, and even if the vehicle door reaches the overopen position, the stress acting on the case can be reduced.

  Hereinafter, embodiments of the present invention will be described. FIG. 1 is a schematic view of a vehicle on which a door check device according to this embodiment is mounted. A vehicle V shown in FIG. 1 includes a vehicle body B and a vehicle door DR. A boarding opening OP is formed in a side portion of the vehicle body B. A pair of door hinges H, H are attached to the edge (front edge) FE of the opening OP in front of the vehicle along the vertical direction. The vehicle door DR is connected to the vehicle body B through a pair of door hinges H and H so as to be swingable. Therefore, the vehicle door DR can open and close the opening OP formed in the vehicle body B.

  FIG. 2 is a diagram showing in detail part A of FIG. As shown in FIG. 2, the pair of door hinges H and H include coaxial hinge shafts H1 and H1, respectively. When the vehicle door DR is opened and closed, the vehicle door DR swings with respect to the vehicle body B about the hinge shafts H1 and H1. Further, the bracket BR is fixed to the front edge part FE by fastening means such as a bolt. One end of a check bar 2 that is a component of the door check device according to the present embodiment is connected to the bracket BR via a pin P. A check rod 2 whose one end is swingably connected to the vehicle body B is a hole formed in the front end portion DE of the vehicle door DR, which is a portion facing the front edge portion FE of the vehicle body B when the vehicle door DR is fully closed. Via S, it extends into the vehicle door DR.

  FIG. 3 is a diagram illustrating the door check device 1 according to the present embodiment. As shown in FIG. 3, the door check device 1 includes a check bar 2, a case 3, a sliding member 4, and a stopper member 5. In FIG. 3, the case 3 and the sliding member 4 are shown in a cross-sectional view, and the check rod 2 and the stopper member 5 are shown in a view as seen from above when the door check device 1 is attached to a vehicle.

  The check bar 2 has an elongated shape, and one end 2a thereof is fixed to the vehicle body B so as to be swingable as described above. The swing center position of the check bar 2 is indicated by a point OC in FIG. The check bar 2 may be formed in a straight line shape, but may have a slightly bent portion as shown in FIG. It is preferable that the amount of bending or the bent portion is designed so that the check rod 2 extended into the vehicle door DR does not interfere with the storage components in the vehicle door DR.

  The case 3 has a base portion 31 and a cover portion 32. The base portion 31 is fixed to the front end DE of the vehicle door DR within the vehicle door DR. The base portion 31 is in contact with the front end portion DE of the vehicle door DR and extends to the right in FIG. 3 from the outer edge of the fixed wall portion 311 toward the inside of the vehicle door DR. And a cylindrical first side wall portion 312. The cover part 32 includes a second side wall part 321 and a locking wall part 322. The second side wall portion 321 is formed in a cylindrical shape, has a portion facing the inner side of the first side wall portion 312 in the circumferential direction, and toward the right side of FIG. 3 from the facing portion toward the inside of the vehicle door DR. It extends. The locking wall portion 322 is bent from the right end surface of the second side wall portion 321 to the inside of the second side wall portion 321 in FIG. 3. By connecting the facing portions of the first side wall portion 312 and the second side wall portion 321, the base portion 31 and the cover portion 32 are integrated.

  A first insertion hole 322 a is formed at the center of the locking wall portion 322. The diameter of the first insertion hole 322a is larger than the diameter of the check rod 2. The check rod 2 extending into the vehicle door DR is inserted through the first insertion hole 322a. Further, a second insertion hole 311 a is formed in the fixed wall portion 311 of the base portion 31. The diameter of the second insertion hole 311a is also larger than the diameter of the check rod 2. The second insertion hole 311a is formed at the same position as the hole S formed in the front end portion DE of the vehicle door DR. Then, the check rod 2 inserted through the first insertion hole 322a further passes through the second insertion hole 311a and the hole S and protrudes from the vehicle door DR. Therefore, the check bar 2 is slidably connected to the vehicle body B side at one end 2a thereof while passing through the case 3.

  The sliding member 4 is attached to the inside of the second side wall portion 321 of the cover portion 32. The sliding member 4 is preferably composed of a member that exhibits elastic force such as rubber or resin, or a material having a large friction coefficient. The sliding member 4 is in contact with the side surface of the check rod 2 penetrating the cover portion 32, and applies a sliding resistance force to the check rod 2 when the check rod 2 moves. As can be seen from FIG. 3, the sliding member 4 is provided in the cover portion 32 so as to sandwich both side surfaces of the check rod 2 from two opposing directions in a plane perpendicular to the longitudinal direction of the check rod 2. In the example shown in FIG. 3, sliding members 4 are arranged on both sides of the check rod 2 when the check rod 2 is viewed from above, and one sliding member abuts one side surface of the check rod 2 and the other The sliding member abuts against the other side surface of the check rod 2.

  The stopper member 5 is provided at the other end of the check bar 2. The stopper member 5 may be formed integrally with the check rod 2 or may be formed as a separate member from the check rod 2 and then assembled to the check rod 2.

  The stopper member 5 has a connecting part 51 and a head part 52, and the head part 52 is connected to the other end 2 b of the check bar 2 via the connecting part 51. As shown in FIG. 3, the head portion 52 has a trapezoidal shape when viewed from above. The length in the top view of the base end surface 521 that is the end surface on the side close to the check bar 2 of the head portion 52 is longer than the length in the top view of the distal end surface 522 that is the end surface on the far side. Further, the length of the base end surface 521 of the head portion 52 in the top view is longer than the length of the first insertion hole 322a formed in the cover portion 32 in the top view.

  When the check bar 2 is viewed from the direction shown in FIG. 3 (above), the length between both side surfaces of the check bar 2 along the direction perpendicular to the longitudinal direction of the check bar 2 is the one end 2a of the check bar 2. To the middle position 2c in the longitudinal direction has the same length D2. On the other hand, in the region from the intermediate position 2c to the other end 2b, the length between both side surfaces increases as the other end 2b is approached. Therefore, the length D1 between both side surfaces at the other end 2b is the largest. That is, a tapered portion 2d is formed in a portion from the intermediate position 2c in the longitudinal direction of the check bar 2 to the other end 2b so that the length between the both side surfaces increases from one end to the other end.

  In the door check device 1 having such a configuration, when the vehicle door DR swings with respect to the vehicle body in order to open and close the opening OP of the vehicle body B, one of the check bars 2 that are swingably connected to the vehicle body B side. The position of the end 2a is displaced relative to the vehicle door DR. At this time, the check rod 2 extended into the vehicle door DR moves relative to the vehicle door DR and the case 3 within the vehicle door DR.

  FIG. 4 is a diagram showing a relative movement state of the check bar 2 when the vehicle door DR is opened and closed. In FIG. 4, the swing center position of the vehicle door DR is indicated by a point OB. Further, the swing center position of the check rod 2 viewed from the vehicle door DR side is indicated by points OC1 to OC5. As the vehicle door DR is opened, the swing center position of the check rod 2 passes through the point OC1, the point OC2, the point OC3, the point OC4, and the point OC5 in this order when viewed from the vehicle door DR. Move to. The movement trajectory from the point OC1 to the point OC5 draws an arc centered on the point OB.

  With the above-described movement of the swing center position of the check bar 2, the check bar 2 moves relative to the vehicle door DR and the case 2 as shown in FIG. Specifically, as the vehicle door DR is opened, the check bar 2 moves relative to the vehicle door DR and the case 3 so as to be pulled out from the vehicle door DR. At this time, the sliding member 4 in the case 3 slides on both side surfaces of the check bar 2, whereby a resistance force (sliding resistance force) against the relative movement of the check bar 2 is applied to the check bar 2. The resistance force against the relative movement of the check rod 2 acts on the vehicle door DR as a resistance force when the vehicle door DR is opened. For this reason, the vehicle door DR can be opened while receiving an appropriate resistance.

  Further, as the opening operation of the vehicle door DR proceeds, the contact position of the pair of sliding members 4, 4 on the check rod 2 changes from the one end 2a side to the other end 2b side of the check rod 2. When the pair of sliding members 4, 4 slides in the region between the one end 2a of the check bar 2 and the intermediate position 2c, both sides of the check bar 2 sandwiched between the pair of sliding members 4, 4 The length between faces does not change. Therefore, while the pair of sliding members 4 and 4 slides in this region, a constant pressing force is applied to the check rod 2 from the sliding members 4 and 4. Therefore, a constant sliding resistance acts on the check rod 2. On the other hand, when the pair of sliding members 4 and 4 slides on the tapered portion 2d between the intermediate position 2c and the other end 2b of the check rod 2, the check rod 2 of the pair of sliding members 4 and 4 is used. As the contact position toward the other end 2b of the check bar 2 increases, the length between both side surfaces of the check bar 2 increases. For this reason, as the check rod 2 is pulled out from the vehicle door DR with the opening operation of the vehicle door DR, the pressing force acting on the check rod 2 from the sliding members 4 and 4 increases. For this reason, the sliding resistance acting on the check rod 2 gradually increases. Thus, by gradually increasing the sliding resistance acting on the check rod 2 when the vehicle door DR is opened, the moving speed of the check rod 2 is reduced.

  When the swing center position of the check bar 2 reaches the point OC5 in FIG. 4, the vehicle door DR is opened to the fully open position. At this time, the stopper member 5 provided on the other end 2b of the check rod 2 is engaged with the cover portion 32 of the case 3, whereby the fully open position of the vehicle door DR is defined and the position from the fully open position of the vehicle door DR is determined. Opening operation is restricted.

  FIG. 5 is a diagram illustrating an engagement state between the stopper member 5 and the case 3 when the vehicle door DR is opened to the fully opened position. When the vehicle door DR is opened to the fully open position, as shown in FIG. 5, the base end surface 521 of the head portion 52 of the stopper member 5 is inserted into the engagement wall portion 322 of the cover portion 32 of the case 3. The contact surface 322b which is a wall surface around the 322a is engaged in an inclined state. Specifically, in the base end surface 521, the inner portion Q1 that is a portion closer to the swing center position (point OB in FIG. 4) of the vehicle door DR abuts against the contact surface 322b, and the base end surface 521 Engage in a state in which the base end surface 521 is inclined with respect to the contact surface 322b so that a gap G is formed between the outer portion Q2 that is a portion far from the swing center position of the vehicle door DR and the contact surface 322b. To do. That is, the contact state between the stopper member 5 and the case 3 when the vehicle door DR is opened to the fully opened position is a one-sided state. The gap G is preferably 1 mm or more, but is not limited thereto.

  FIG. 6 is a diagram showing an engagement state between the stopper member 5 and the case 3 when the vehicle door DR further opens from the fully open position and reaches the overopen position. In addition, when the vehicle door DR is opened with a strong force (opened), the open / close position of the vehicle door DR may reach the overopen position beyond the fully open position.

  When the opening / closing position of the vehicle door DR is opened from the fully open position to the overopen position, the stopper member 5 hits the case 3 strongly. Further, with the opening operation of the vehicle door DR from the fully open position to the overopen position, one end of the check rod 2 moves about the swing center position of the vehicle door DR and the stopper member 5 connected to the check rod 2. Tries to move in a circular arc shape around the center position of the swing of the vehicle door DR. In such a case, the movement amount of the portion farther than the swing center position of the vehicle door DR on the base end surface 521 of the stopper member 5 is larger than the movement amount of the near portion.

  Here, when the vehicle door DR is in the fully open position, as shown in FIG. 5, the stopper member 5 comes into contact with the case 3 and from the swing center position of the vehicle door DR on the base end surface 521 of the stopper member 5. Only the inner part Q1 on the near side abuts against the contact surface 322b, and the outer part Q2 on the far side floats. When the vehicle door DR is opened to the overopen position in such a state, the outer portion Q2 also comes into contact with the contact surface 322b, and the outer portion Q2 moves more than the inner portion Q1, so that the stopper The base end surface 521 of the member 5 and the contact surface 322b of the case 3 are made parallel. That is, when the open / close position of the vehicle door DR reaches the overopen position, the contact state between the stopper member 5 and the case 3 is brought into a contact state, and the base end surface 521 of the stopper member 5 and the contact surface between the case 3 and the like. 322b is made parallel. For this reason, when the opening / closing position of the vehicle door DR reaches the over-open position, the contact area between the stopper member 5 and the case 3 is increased, and the base end surface 521 uniformly contacts the entire contact surface 322b. Therefore, the stress acting on the case 3 is dispersed, and the stress per unit area acting on the case 3 is reduced. As a result, large local deformation of the case 3 can be prevented and the deformation amount can be reduced.

  FIG. 7 is a diagram showing an engagement state between the stopper member 5 and the case 3 when the vehicle door DR is opened to the fully opened position using the conventional door check device. When the conventional door check device is used, when the vehicle door DR is opened to the fully open position, the base end surface 521 of the head portion 52 of the stopper member 5 hits the locking wall portion 322 of the cover portion 32 of the case 3. Engages parallel to surface 322b. That is, in the base end surface 521, the inner portion Q1 closer to the swing center position (point OB in FIG. 4) of the vehicle door DR and the outer portion Q2 farther from the contact surface 322b abut. That is, the stopper member 5 hits the case 3 when the vehicle door DR is opened to the fully open position.

  FIG. 8 is a diagram showing an engaged state between the stopper member 5 and the case 3 when the vehicle door DR further opens from the state shown in FIG. 7 and reaches the overopen position. When the opening / closing position of the vehicle door DR is opened to the overopen position, the stopper member 5 hits the case 3 strongly. Here, when the conventional door check device is used, when the vehicle door DR is in the fully open state, the stopper member 5 has already come into contact with the case 3, so the open / close position of the vehicle door DR reaches the overopen position. When the opening operation is performed, since the movement amount of the outer portion Q2 far from the swing center position of the vehicle door DR in the stopper member 5 is larger than the movement amount of the inner portion Q1, the strong stress is exerted on the outer portion Q2. Acts and the case 3 is greatly deformed at the contact portion with the outer portion Q2.

  That is, according to the prior art, when the vehicle door DR is opened to the overopen position, the stress acting on the case 3 is concentrated on a part of the case 3, so that the case 3 is locally deformed and the amount of deformation is also very large. Big. On the other hand, according to the present embodiment, when the vehicle door DR is opened to the overopen position, the stress acting on the case 3 is dispersed. Local deformation can be avoided, and the amount of deformation can be reduced by stress distribution. For this reason, according to the present embodiment, it is possible to effectively suppress deformation of the case 3 when the opening / closing position of the vehicle door DR reaches the excess position.

  As described above, the door check device 1 according to the present embodiment has one end 2a that is swingably connected to the vehicle body B and can swing with respect to the vehicle body B in order to open and close the opening OP of the vehicle body B. A check rod 2 that extends into the connected vehicle door DR and moves relative to the vehicle door DR so as to be pulled out from the vehicle door DR when the vehicle door DR is opened, and is fixed within the vehicle door DR. At the same time, a case 3 in which an insertion hole 322a for inserting the check rod 2 extending into the vehicle door DR is formed, and the case 3 is provided in the case 3, and a sliding resistance force is exerted on the check rod 2 in the case 3. Provided on the sliding member 4 to be applied and the other end 2b of the check bar 2 and engageable with a contact surface 322b which is a wall surface around the insertion hole 322a of the case 3 when the vehicle door DR is opened to the fully open position. Naive end face 52 It includes a stopper member 5, a with (engagement surface). When the vehicle door DR is opened to the fully open position, the contact state between the base end surface 521 and the contact surface 322b is an inward portion of the base end surface 521 that is closer to the swing center position of the vehicle door DR. The part Q1 abuts against the contact surface 322b, and the vehicle door DR is further over-opened from the fully open position, with a gap G formed between the outer part Q2 and the contact surface 322b on the far side. When the opening operation is performed to the position, the contact state between the base end surface 521 and the contact surface 322b is brought into a contact state where both the inner portion Q1 and the outer portion Q2 are in contact with the contact surface 322b. Further, the door check device 1 according to the present embodiment engages in a state where the base end surface 521 of the stopper member 5 is inclined to the contact surface 322b of the case 3 when the vehicle door DR is opened to the fully open position. When the door DR is opened to the overopen position, the base end surface 521 is configured to engage in a state parallel to the contact surface 322b.

  According to the present embodiment, when the open / close position of the vehicle door DR is the fully open position, the gap G is formed between the case 3 and the outer portion Q2 of the stopper member 5, whereby the stopper member 5 and the case 3 are It will be in a one-sided state. When the vehicle door DR is opened to the overopen position, the stopper member 5 and the case 3 are brought into a contact state. For this reason, when the opening / closing position of the vehicle door DR is an over-open position that is more open than the fully-open position, the contact area between the stopper member 5 and the case 3 is increased, and the stopper member 5 is uniformly applied to the entire contact surface 322b. The proximal end surface 521 can be brought into contact. Thus, by expanding the contact area and dispersing the stress acting on the case 3 from the stopper member 5, the deformation of the case 3 can be suppressed and the local deformation of the case 3 can be prevented.

  In addition, by considering the gap G in advance when designing the door check device 1, it is possible to provide a door check device that can exhibit the above-described effects that cannot be sufficiently achieved depending on a gap that occurs by chance.

  Further, the sliding member 4 is configured to sandwich both side surfaces of the check bar 2 in a plane perpendicular to the longitudinal direction of the check bar 2. And the taper part 2d which the length between both side surfaces increases as it goes to the other end 2b from the one end 2a is formed in the part from the intermediate position 2c in the longitudinal direction of the check rod 2 to the other end 2b. . For this reason, when the sliding member 4 slides on the taper portion 2d of the check rod 2, the sliding resistance acting on the check rod 2 is increased as the vehicle door approaches the fully open position. Therefore, the collision speed between the stopper member 5 and the case 3 when the vehicle door DR reaches the fully open position can be reduced. As a result, the vehicle door DR can be effectively prevented from being opened to the overopen position, and even if the vehicle door is opened to the overopen position, the stress acting on the case 3 can be reduced.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. For example, in the present embodiment, when the vehicle door DR is in the fully open position, the stopper member 5 and the case 3 are in contact with each other, but the shapes of the check bar 2, the case 3 and the stopper member 5 for making contact with each other are as follows. There is no particular limitation. For example, as shown in FIG. 9A, the stopper member 5 and the case 3 may be brought into contact with each other by inclining the longitudinal direction of the linear check rod 2 with respect to the contact surface 322b of the case 3. Further, as shown in FIG. 9B, the stopper member 5 and the case 3 may be brought into contact with each other by bending the other end 2b side of the check bar 2. Further, as shown in FIG. 9C, the stopper member 5 and the case 3 are caused to contact each other by inclining the base end surface 521 of the stopper member 5 with respect to the direction orthogonal to the longitudinal direction of the check rod 2. Also good. Further, as shown in FIG. 9 (d), by forming the case 3 such that the portion of the contact surface 322b of the case 3 that faces the outer portion Q2 is shorter than the portion that faces the inner portion Q1. Alternatively, the stopper member 5 and the case 3 may be brought into contact with each other. Moreover, in the said embodiment, although illustrated about the door check apparatus applied at the time of the opening / closing operation | movement of the vehicle door DR provided in the side of the vehicle body B, the opening / closing operation | movement of other swing doors, such as a back door, is also illustrated. A door check device may be applied. Thus, the present invention can be modified as appropriate without departing from the spirit of the present invention.
