Description

  The present invention relates to a check link device that defines a maximum opening position of a door.

  Conventionally, a check link device is used to define the maximum opening position of the door with respect to the vehicle body. The check link device includes, for example, a holding member on a door and an arm on a vehicle body. The holding member has an insertion portion through which the arm is slidably inserted. The arm is a plate-shaped member formed in a substantially T shape, and has a base portion and a stopper portion. The base is a portion extending in the length direction. The stopper portion is a portion extending in the width direction from one end portion of the base portion. A pin hole is formed at the other end of the base of the arm. In this arm, the swing pin is inserted into the pin hole in a state where the base portion is slidably inserted into the insertion portion of the holding member. Thus, the arm is held by the vehicle body so as to be swingable around an axis parallel to the swing axis of the door via the swing pin inserted through the pin hole.

  In this check link device, when the door is swung in the opening direction with respect to the vehicle body, the holding member provided on the door swings the arm around the axis of the swinging pin as appropriate. On the other hand, it moves to the stopper part side. During this time, the inner wall surface of the insertion portion of the holding member is in sliding contact with the end surface in the width direction of the arm. When the door is further swung in the opening direction with respect to the vehicle body, the holding member provided on the door eventually comes into contact with the stopper portion of the arm. Thereby, it is possible to prevent the door from further swinging in the opening direction with respect to the vehicle main body, and it is possible to define the maximum opening position of the door with respect to the vehicle main body.

  In this type of check link device, the arm can be composed of a single steel plate. Therefore, the number of components can be reduced as compared with a case in which the arm is composed of a plurality of members, and the weight of the arm can be reduced and the processing cost can be reduced.

  By the way, in the check link device in which the arm is composed of a single steel plate as described above, it is essential to configure the length of the stopper portion in the arm in the width direction longer than the base portion. Therefore, when the door or the vehicle main body is downsized, there is a possibility that the stopper portion of the arm may be a factor that hinders this. That is, for example, when the arm is held on the vehicle main body so as to be swingable about an axis parallel to the swing axis of the door as described above, the door corresponds to the length in the width direction of the stopper portion of the arm. There was a risk of an increase in size.

  Therefore, in a conventional check link device, a portion between the base and the stopper (hereinafter referred to as “twisted portion”) is twisted in order to change the extending direction of the stopper with respect to the base in the arm. Things are also provided. According to such a check link device, the extending direction of the stopper portion relative to the base portion in the arm can be changed in the thickness direction of the arm by twisting. Therefore, the door and the vehicle main body only need to be able to correspond to the width direction length of the base portion of the arm, and the door and the vehicle main body can be reduced in size after the arm is formed of a single steel plate (for example, Patent Documents). 1).

  However, in the conventional check link device, when the arm is twisted, the edge extends in the direction intersecting the longitudinal direction of the base portion at the end portion positioned in the width direction in the twisted portion. Therefore, when the door is swung in the opening direction with respect to the vehicle body, if the insertion portion of the holding member reaches the twisted portion of the arm, the inner wall surface and the edge of the insertion portion may be caught. The dynamic operation may not be smooth.

  In view of the above circumstances, an object of the present invention is to provide a check link device that can prevent a decrease in swing operability of a door without incurring an increase in the size of a vehicle body or a door.

  The check link device according to claim 2 of the present invention is the check link device according to claim 1, wherein the stopper portion forms a contact portion at a position closer to the shaft side of the base portion than the twisted portion. When the door is opened with respect to the vehicle body, the holding member and the contact portion come into contact with each other, thereby preventing the inner wall surface of the insertion portion from contacting the twisted portion. And

  The check link device according to claim 3 of the present invention is the check link device according to claim 2, in which the stopper portion is connected to the torsion portion, and the base portion is directed toward the shaft side of the base portion. And an extending end portion of the abutting portion is bent in a direction crossing the extending direction.

  The check link device according to claim 4 of the present invention is the check link device according to claim 3 described above, wherein the contact portion is in a direction opposite to a direction in which an end surface is directed toward the stopper portion side in the twisted portion. The extending end portion is bent toward the end.

  When the door D is further swung in the opening direction with respect to the vehicle main body B from the above state, as shown in FIG. As shown by a two-dot chain line in FIG. 2, the arm 20 is provided on the base 21 of the arm 20 as shown by a two-dot chain line while appropriately swinging the arm 20 counterclockwise around the axis of the swing pin 51 via the moving body 15. The first check unit 41 is reached. In this state, the movement of the pair of sliding bodies 15 from the first check portion 41 is restricted by the elastic force of the pair of elastic bodies 14 and the recess shape of the synthetic resin layer 40, and the vehicle body B In contrast, the door D can be restricted to a desired intermediate open position.

  When the door D is further swung in the opening direction with respect to the vehicle main body B from the above state, as shown in FIG. As indicated by the solid line, the second arm 20 is provided on the base 21 of the arm 20 while appropriately swinging the arm 20 counterclockwise around the axis of the swing pin 51 in FIG. The block surface 12 d provided on the case 12 of the holding member 10 comes into contact with the contact surface 43 provided on the stopper portion 22 of the arm 20. In this state, the elastic force of the pair of elastic bodies 14 and the recess shape of the synthetic resin layer 40 restrict the movement of the pair of sliding bodies 15 from the second check portion 42, and FIG. As shown in b), it is possible to restrict the door D to the vehicle body B in a state opened from the above-described intermediate open position.

  Further, in the state shown by the solid line in FIG. 2, the block surface 12 d provided on the case 12 of the holding member 10 is in contact with the contact surface 43 provided on the stopper portion 22 of the arm 20. Thereby, it is possible to prevent the door D from being further swung in the opening direction with respect to the vehicle main body B, and the maximum opening position of the door D with respect to the vehicle main body B can be defined.

  On the other hand, as shown in FIG. 3A, when the door D is swung in the closing direction with respect to the vehicle main body B from the state described above, the holding member 10 formed on the door D is moved to a pair of sliding members. The arm 20 is moved to the one end side of the base 21 in FIG. 2 with respect to the arm 20 while appropriately swinging the arm 20 clockwise around the axis of the swing pin 51 via the moving body 15 in FIG. . During this time, the pair of sliding bodies 15 has the inner wall surface 15b of the convex portion 15a slidably contact the upper and lower surfaces of the arm 20 by the elastic force of the pair of elastic bodies 14, and a pair of elastic bodies 15 according to the shape of the upper and lower surfaces of the arm 20. The body 14 moves up and down while being appropriately elastically deformed.

  3A, when the door D is further swung in the closing direction with respect to the vehicle main body B, the holding member 10 formed on the door D eventually becomes a pair of slides. The arm 20 is provided on the base 21 of the arm 20 as shown by a two-dot chain line in FIG. 2 while appropriately swinging the arm 20 clockwise around the axis of the swing pin 51 via the moving body 15 in FIG. The first check unit 41 is reached. Thereafter, as shown in FIG. 3 (a), when the door D is disposed at the closed position with respect to the vehicle main body B, a pair of sliding bodies are formed in the holding member 10 formed on the door D as shown in FIG. 15 is again arranged at a position closest to the swing pin 51 side.

  According to the check link device configured as described above, the arm 20 is configured to prevent the sliding body 15 of the holding member 10 from contacting the twisted portion 33 of the steel plate 30. Specifically, the arm 20 forms a contact surface 43 at a position closer to one end of the base 31 than the twisted portion 33 of the steel plate 30. For this reason, when the door D is moved in the opening direction with respect to the vehicle main body B, the block surface provided in the case 12 at a stage before the sliding body 15 of the holding member 10 reaches the twisted portion 33 of the steel plate 30. 12d and the contact surface 43 of the arm 20 contact. Therefore, the sliding body 15 of the holding member 10 can be prevented from coming into contact with the torsional portion 33 of the steel plate 30, so that the arm 20 is twisted so as to avoid the enlargement of the vehicle body B and the door D as in the past. In this case, the swinging operability of the door D is not adversely affected. As a result, it is possible to prevent the swinging operability of the door D from being lowered without increasing the size of the vehicle body B or the door D.

  Further, according to the check link device configured as described above, the contact surface 43 provided on the stopper portion 22 of the arm 20 is replaced with the contact surface 32 c provided on the contact portion 32 b of the steel plate 30 with the synthetic resin layer 40. It is formed by coating. As a result, the load at the time of contacting the block surface 12d of the case 12 can be received by the contact surface 32c of the contact portion 32b. Therefore, for example, when the contact portion 32b of the steel plate 30 is not bent and the tip portion is formed as a contact surface 32c and is covered with the synthetic resin layer 40, the case 12 is in contact with the case 12. The load can be distributed and received over a wide area, and the rigidity can be increased.

  Furthermore, according to the check link device configured as described above, the contact surface 32 c provided on the contact portion 32 b of the steel plate 30 constituting the arm 20 is opposite to the twisting direction of the stopper portion 32 with respect to the base portion 31. It is configured to bend in the direction. Therefore, when the case 12 of the holding member 10 provided in the door D and the contact surface 43 provided on the stopper portion 22 of the arm 20 abut, for example, the direction in which the stopper portion 32 is twisted with respect to the base portion 31. Even when a restoring force is generated in the opposite direction, that is, in the restoring direction of torsion, the front end surface of the contact portion 32b is bent in the restoring direction, so that the frictional force with the synthetic resin layer 40 is increased. And the restoring force of torsion can be suppressed.

  Further, according to the check link device configured as described above, the contact surface 32c provided on the contact portion 32b of the steel plate 30 constituting the arm 20 is provided with the extended end portions of the pair of contact portions 32b. It is configured to bend in directions opposite to each other. Therefore, the contact surfaces 32c can be dispersedly arranged with respect to the synthetic resin layer 40 as compared with the case where the extending end portions of the pair of contact portions 32b are bent in the same direction. Therefore, when the case 12 of the holding member 10 provided in the door D and the contact surface 43 provided on the stopper portion 22 of the arm 20 contact each other, a load is locally applied to a part of the contact surface 43. The situation can be suppressed. Moreover, in the present embodiment, the arm 20 is used to define the maximum open position of the door D disposed on the left side of the front seat in the vehicle main body B. However, the arm 20 is turned upside down, for example, In the vehicle main body B, the maximum opening position of the door D arranged on the left side of the front seat may be defined. That is, the arm 20 can be shared with the left and right doors of the vehicle.

  Further, in the check link device configured as described above, the contact surface 43 is formed on the stopper portion 22 of the arm 20 by covering the contact portion 32b of the steel plate 30 with the synthetic resin layer 40. The impact at the time of contact with the block surface 12d can be absorbed by the synthetic resin layer 40. In addition, in this case, the thickness of the synthetic resin layer 40 covering the contact surface 43 (the length in the direction perpendicular to the contact surface 32c) can be locally increased to further absorb shock.

  In the above-described embodiment, the arm 20 configured by covering the entire outer surface of the steel plate 30 with the synthetic resin layer 40 is illustrated, but the synthetic resin layer 40 may not necessarily be covered. Also in this case, as shown in FIG. 1, if the contact surface 32 c provided on the stopper portion 32 of the steel plate 30 is provided on one end side of the base portion 31 with respect to the torsion portion 33, the door with respect to the vehicle body B is provided. Even if D is swung in the opening direction, the block surface 12d provided on the case 12 and the contact surface 32c of the arm 20 are in a stage before the sliding body 15 of the holding member 10 reaches the twisted portion 33 of the steel plate 30. And abut. Therefore, the sliding body 15 of the holding member 10 can be prevented from coming into contact with the torsion part 33 of the steel plate 30.
