JP, 2013-83056, A

  By the way, in the door-check apparatus for motor vehicles disclosed by patent document 1, the elastic force of an elastic member acts on the case which accommodates an elastic member in the direction on the opposite side to the direction which biases a shoe. If the strength of the case with respect to this elastic force is not sufficient, the case may be deformed so as to expand the opening.

  Then, the place made into the object of the present invention is to provide the door check device for vehicles which raised the intensity to elastic power of an elastic member.

  A vehicle door check device that solves the above problems includes a housing fixed to a vehicle door, a check link rotatably supported by the vehicle body, and an outer surface of the check link inserted into the housing. And an elastic member urging the shoe toward the outer surface of the check link by an elastic force, and the housing has an opening and at least the shoe and the elastic member. And a second housing for closing the opening, wherein any one of the first housing and the second housing supports the first supporting portion for supporting the elastic member. And the other has a second support that supports the first support from the outside in the direction in which the elastic force of the elastic member acts.

  According to the above configuration, the stress due to the elastic force of the elastic member is dispersed to both the first housing and the second housing by the first support portion and the second support portion, and the elastic force of the elastic member causes the first housing and The second housing engages tightly. As a result, deformation of the housing due to the elastic force of the elastic member is suppressed. That is, the strength of the housing to the elastic force of the elastic member can be improved.

  In the door check device for a vehicle, one of the first housing and the second housing having the first support portion is made of a metal material, and the second housing of the first housing and the second housing is made of a metal. The other one having a support is preferably made of a resin material.

  According to the above configuration, by making the first housing out of a resin material, the weight of the housing can be reduced, and the first supporting portion of the second housing that receives mainly the elastic force of the elastic member by coming into contact with the elastic member. The strength of the housing with respect to the elastic force of the elastic member can also be secured by making the metal with a metal material. In the above-mentioned door check device for a vehicle, a convex portion is formed on the peripheral edge of the opening in the first housing, and the second housing is a clamping portion for clamping the peripheral edge of the opening in the first housing, It is preferable that a sandwiching portion having a concave portion engaged with the convex portion is formed.

  Hereinafter, an embodiment of a vehicle door check device (hereinafter, also simply referred to as a door check device) will be described.

  In the following description, the vertical direction of the vehicle is referred to as "vertical direction".

  As shown in FIG. 1, the vehicle 1 includes a vehicle body 2 and a vehicle door 3. In the side portion of the vehicle main body 2, an entrance 2a is formed for the user of the vehicle 1 to get on and off. Further, in the vehicle 1, a pair of door hinges 4 are juxtaposed in the vertical direction at an edge (front edge 2 b) on the vehicle front of the entrance 2 a. The pair of door hinges 4 rotatably supports the vehicle door 3 with respect to the vehicle body 2. Thus, the vehicle door 3 is attached to the vehicle body 2 so as to be able to open and close the entrance 2 a formed in the vehicle body 2. More specifically, as shown in FIG. 2, the vehicle door 3 is rotatably supported about an axis 4 a of the door hinge 4 that substantially coincides with the vertical direction of the vehicle.

  Further, as shown in FIG. 2, a bracket 5 is fixed to the front edge 2 b of the vehicle body 2 by a fastening member such as a bolt. The bracket 5 supports the pin 6 in a state in which the axial direction of the pin 6 substantially coincides with the vertical direction. The bracket 5 rotatably supports the check link 10, which is a component of the door check device 100 of the present embodiment, via the pin 6 so as to be rotatable about the shaft 6 a of the pin 6. The check link 10 extends into the vehicle door 3 through a hole 3 a formed in the front end of the vehicle door 3 when the vehicle door 3 is fully closed. The check link 10 enters into the vehicle door 3 with the closing operation of the vehicle door 3 or withdraws from the inside of the vehicle door 3 with the opening operation of the vehicle door 3.

  FIG. 3 is a sectional view taken along line AA of the front view of the door check device 100 shown in FIG. 4 is an exploded perspective view of the door check device 100. As shown in FIG. As shown in FIG. 3 and FIG. 4 together, the door check device 100 includes the check link 10 described above, the two shoes 30 sliding on the outer surface of the check link 10, and the outer surface of the check link 10. And a housing 40 having the insertion holes 41a and 42a for inserting the check link 10 and the shoe 30 and the elastic member 20 housed therein.

  As shown in FIG. 3, the check link 10 has an elongated arm 11, a mounting portion 12 at one end of the arm 11, and a stopper 13 at the other end of the arm 11. An uneven check pattern 11 a is formed on the arm 11 by changing the thickness in the vertical direction. The mounting portion 12 has an axial hole 12 a formed to penetrate in the vertical direction. By inserting the pin 6 into the axial hole 12a, the check link 10 (door check device 100) rotates around the axis 6a of the pin 6 by the pin 6 with the other end of the arm 11 as a free end. It is supported movably. The stopper 13 is set larger in size than the arm 11 in the direction orthogonal to the longitudinal direction of the arm 11. The inside of the check link 10 is made of a metal material, and the surface of the metal material is coated with a resin material.

  The two shoes 30 are accommodated in the housing 40 so as to be vertically movable in such a manner as to sandwich the check link 10 in the vertical direction. Each shoe 30 is made of a resin material.

  The two elastic members 20 are accommodated in the housing 40 in such a manner that the two elastic members 20 are respectively held by the housing 40 and the shoe 30 in the vertical direction. In the present embodiment, each elastic member 20 is constituted by a compression coil spring made of spring steel. Further, each elastic member 20 elastically deforms in the vertical direction to exert elastic force on both sides in the vertical direction. Each elastic member 20 biases the shoes 30 toward the outer surface of the check link 10 by one of the elastic forces.

  When the check link 10 enters or retracts into the vehicle door 3 as the vehicle door 3 is opened and closed, the check link moves in the longitudinal direction relative to the housing 40. With the movement of the check link 10, the shoe 30 sliding on the outer surface of the check link 10 moves up and down according to the check pattern 11a. At this time, when the amount of elastic deformation in the vertical direction of the elastic member 20 changes, the elastic force of the elastic member 20 biasing the shoe 30 changes. As a result, the sliding resistance between the check link 10 and the shoe 30 changes. Thus, when the user of the vehicle 1 opens and closes the vehicle door 3, an appropriate operating force corresponding to the opening degree of the vehicle door 3 is generated.

  As described above, in the present embodiment, the direction in which the elastic member 20 elastically deforms, that is, the direction in which the elastic force of the elastic member 20 acts, substantially coincides with the vertical direction. However, the direction in which the elastic member 20 acts may be coincident with the direction in which the shoe 30 moves in accordance with the check pattern 11a. Further, in the present embodiment, a compression coil spring is used as the elastic member 20, but any elastic material such as a rubber material may be used as long as it exerts an elastic force.

  Next, with reference to FIG. 4, the configuration of the housing 40 in the present embodiment will be described. In the following description, in the radial direction centering on the axis 6 a of the pin 6, the direction passing through the centers of the insertion holes 41 a and 42 a of the housing 40 is referred to as “front-rear direction”. Moreover, let the radial direction inner side be "front direction" among the said radial directions, and let the radial direction outer side be "rear direction." Furthermore, a direction orthogonal to both the vertical direction and the front-rear direction is referred to as a “width direction”.

  As shown in FIG. 4, the housing 40 is configured to include a first housing 41 and a second housing 42.

  The first housing 41 is in the form of a box with an open bottom and an opening 41b formed on one surface of a substantially rectangular parallelepiped in the forward direction. Specifically, the first housing 41 extends from the bottom wall portion 413 having a surface facing the opening 41 b to the second housing 42 side (forward direction) from both ends in the vertical direction of the bottom wall portion 413 and also in the vertical direction And two second side wall portions extending substantially orthogonal to the width direction from the both ends in the width direction of the two first side wall portions 411 and the bottom wall portion 413 substantially orthogonal to each other. And 412 are connected to form a box with an open bottom and no lid. The first housing 41 accommodates the shoe 30 and the elastic member 20 through the opening 41 b. An insertion hole 41 a of the first housing 41 for inserting the check link 10 is formed to penetrate at the center of the bottom wall portion 413. Further, the size of the insertion hole 41 a is set to be larger than the arm 11 of the check link 10 and smaller than the stopper 13 of the check link 10 in the direction orthogonal to the front-rear direction. For this reason, when the check link 10 leaves the vehicle door 3 due to the opening operation of the vehicle door 3 (when the check link 10 moves relative to the vehicle door 3 to the left side shown in FIG. 3) The stopper 13 and the housing 40 abut on each other. Thus, the fully open position of the vehicle door 3 is positioned without completely removing the check link 10 from the vehicle door 3. Further, the second side wall portion 412 of the first housing 41 is formed with a convex portion 41 c which protrudes outward in the width direction from the peripheral edge of the opening 41 b in the middle portion in the vertical direction.

  The first housing 41 is integrally manufactured by injection molding of a resin material such as polyamide resin.

  As shown in FIG. 4, the second housing 42 includes a plate-like lid 421 that closes the opening 41 b of the first housing 41, and two sandwiching portions 422 extending from both ends in the width direction of the lid 421. And two tongue pieces 423 extending from both ends in the vertical direction of the lid 421.

  Similarly to the first housing 41, an insertion hole 42a for inserting the check link 10 is formed through the center of the lid 421. The size of the insertion hole 42a is set larger than the arm 11 of the check link 10 in the direction orthogonal to the front-rear direction. Further, the lid 421 has a rivet 421a that protrudes in the rear direction on the upper side and the lower side of the insertion hole 42a. The second housing 42 (housing 40) is fixed to the vehicle door 3 by connecting the nut 7 (shown in FIG. 3) to the rivet 421 a through the vehicle door 3.

  The two pinching portions 422 extend from the lid portion 421 to the first housing 41 side (rear direction), and have a plate shape substantially orthogonal to the width direction. Further, the sandwiching portion 422 has a recess 42 b which is formed to penetrate in the width direction.

  The two tongue pieces 423 extend from the lid 421 toward the first housing (in the rear direction), and have a substantially square plate shape substantially orthogonal to the vertical direction. The length by which the two tongue portions 423 extend in the first housing side (rear direction) is set to be substantially the same as the length by which the first side wall 411 of the first housing 41 extends in the second housing 42 side. Further, the distance between the outer surfaces in the vertical direction of the two tongue pieces 423 is set to be slightly shorter than the distance between the inner surfaces in the vertical direction of the two first side wall portions 411 of the first housing 41.

  The second housing 42 is made of a plate material made of metal such as steel having a density (mass per unit volume) larger than that of the resin material constituting the first housing 41 and being hard to bend (having a large elastic coefficient). . More specifically, the second housing 42 is formed by pressing through the insertion holes 42a and the recess 42b with respect to a metal plate material, and then bending the tongue piece 423 and the holding portion 422 with respect to the lid 421 by bending. It is made by.

  Here, with reference to FIG. 5 and FIG. 6, the connection method of the 1st housing 41 and the 2nd housing, and the composition of door check device 100 in the state where the 1st housing 41 and the 2nd housing 42 were connected are explained.

  5 is a cross-sectional view taken along line B-B of the front view of the door check device 100 shown in FIG. As shown in FIG. 5, in order to couple the first housing 41 and the second housing 42, the second housing 42 is pushed relative to the first housing 41 in a direction (arrow direction shown in FIG. 5) orthogonal to the opening 41b. Just do it. Specifically, when the second housing 42 is pushed in, the sandwiching portion 422 elastically deforms outward in the width direction, and by further pushing in, the concave portion 42 b of the sandwiching portion 422 fits into the convex portion 41 c of the first housing 41 and concavoconvex engagement Do. As described above, so-called “snap-fit engagement” utilizing the elasticity of the second housing 42 is adopted for coupling the first housing 41 and the second housing 42. Further, in a state where the first housing 41 and the second housing 42 are coupled, the sandwiching portion 422 sandwiches the periphery of the opening 41 b of the first housing 41. Accordingly, the sandwiching portion 422 positions the second housing 42 in the width direction with respect to the first housing 41 and suppresses deformation such that the opening 41 b of the first housing 41 is expanded by an external force.

  As shown in FIG. 6, in the state where the first housing 41 and the second housing 42 are coupled, the tongue piece portion 423 of the second housing 42 is accommodated inside the first side wall portion 411 of the first housing 41 in the vertical direction. It is done. Thus, when the tongue piece portion 423 of the housing 40 abuts on the elastic member 20, it functions as a "first support portion" that supports the elastic member 20 in the direction (vertical direction) in which the elastic force of the elastic member 20 acts. Do. Further, in a state in which the first housing 41 and the second housing 42 are coupled, the first side wall 411 of the first housing 41 has a direction in which the elastic force of the elastic member 20 acts on the tongue piece 423 of the second housing 42 ( Support from the outside in the vertical direction). Thus, the first side wall 411 of the housing 40 functions as a “second support” that supports the “first support” from the outside in the direction in which the elastic force of the elastic member 20 acts. The tongue piece 423 as the “first support portion” and the first side wall 411 as the “second support portion” are elastic members 20 in the direction in which the elastic force of the elastic member 20 acts (vertical direction). It is always in contact by the elastic force of At this time, the tip of the tongue piece 423 as the "first support" is positioned at the base end of the first side wall 411 as the "second support".

  In the following description, the tongue piece portion 423 of the second housing 42 is also referred to as "first support portion S1". Further, the first side wall 411 of the first housing 41 is also referred to as "second support S2".

  Next, the operation of the door check device 100 of the present embodiment will be described with reference to FIGS.

  As shown in FIG. 6, in the door check device 100 of the present embodiment, the first support portion S1 supports the elastic member 20, and the second support portion S2 is the outer side in the direction in which the elastic force of the elastic member 20 acts. To the first support portion S1. That is, the first housing 41 and the second housing 42 closely contact and overlap in the direction in which the elastic force of the elastic member 20 acts. Thereby, the elastic force of the elastic member 20 first acts on the first support portion S1, and the elastic force via the first support portion S1 further acts on the second support portion S2. That is, the elastic force of the elastic member 20 acts on both the first housing 41 and the second housing 42. As a result, the stress received by the housing 40 from the elastic member 20 is dispersed to both the first housing 41 and the second housing 42.

  Further, the first support portion S1 of the second housing 42 and the second support portion S2 of the first housing 41 are firmly meshed by the elastic force of the elastic member 20. Specifically, a frictional force is generated in the direction substantially orthogonal to the direction in which the elastic force acts on the contact surface between the first support portion S1 and the second support portion S2 by the elastic force. In addition, this frictional force increases as the elastic force of the elastic member 20 increases. Due to this frictional force, the first support portion S1 and the second support portion S2, which always abut, are difficult to slide and move relative to each other.

  Then, one of the first housing 41 and the second housing 42 in which the first support portion S1 is formed (in the present embodiment, the second housing 42) is made of a metal material, and is in contact with the elastic member 20. Therefore, the first support portion S1 mainly receiving the elastic force is made of a high strength material.

  Furthermore, the direction in which the first support portion S1 is formed (in the present embodiment, the second housing 42) is made of a metal material, and the direction in which the second support portion S2 is formed (in the present embodiment, the first housing) 41) is made of a resin material that is more easily bent than a metal material. Thereby, as shown in FIG. 7, when the first support portion S1 is slightly deformed by the elastic force of the elastic member 20, the first support portion S1 bites into the second support portion S2 (shown by a two-dot chain line). In this manner, the first support portion S1 plays the role of an anchor, whereby the second housing 42 is further less likely to be detached from the first housing 41. In addition, such an effect | action becomes more remarkable by setting the length of 1st support part S1 so that the front-end | tip of 1st support part S1 may be located in the base end of 2nd support part S2. That is, when the tip of the first support portion S1 bites into the proximal end of the second support portion S2, the second housing 42 is further less likely to be detached from the first housing 41.

  As shown in FIG. 5, the sandwiching portion 422 of the second housing 42 sandwiches the periphery of the opening 41 b of the first housing 41. According to this sandwiching portion 422, for example, when the user of the vehicle 1 opens the vehicle door 3 to the fully open position, that is, when the stopper 13 and the housing 40 abut, the opening 41b is received by the load received from the stopper 13. It is suppressed that the first housing 41 is deformed so as to expand. The first housing 41 and the first housing 41 are formed at the position where the deformation of the first housing 41 is suppressed by the holding portion 422 by forming the concave portion 42b engaged with the convex portion 41c of the first housing 41 in the holding portion 422. (2) The housing 42 is engaged in an irregular manner.

  According to the configuration of the door check device 100 of the present embodiment described above, the following effects can be obtained.

  -By providing the first support portion S1 and the second support portion S2 in the housing 40, stress received from the elastic member 20 can be dispersed to both the first housing 41 and the second housing 42, or the first housing 41 and the second housing 42 can be provided. The strong meshing of the housing 42 can make it difficult for the housing 40 to be deformed. Thus, the strength of the housing 40 against the elastic force of the elastic member 20 can be improved.

  -The first housing 41 in which the second support portion S2 is formed is made of a resin material, and the weight is reduced, and the second housing 42 in which the first support portion S1 is formed is made of a metal material. The strength of the housing 40 against the elastic force of the elastic member 20 can also be secured.

  -The 1st support part S1 is an anchor by producing the 2nd housing 42 in which the 1st support part S1 is formed by metal material, and producing the 1st housing 41 in which the 2nd support part S2 is formed by resin material The second housing 42 does not easily come off with respect to the first housing 41. As a result, it is possible to prevent the members (the elastic member 20 and the shoes 30) accommodated in the first housing 41 from falling off the opening 41b.

  The first housing 41 and the second housing 42 are engaged with each other at a position where the deformation of the first housing 41 is suppressed by the holding portion 422. This makes it possible to secure a sufficient bonding force even in the case of a concavo-convex engagement in which the bonding force is weak as compared with the bonding means and the like generally using a fastening member. And since fastening members, such as a bolt, become unnecessary, it can not only suppress the increase in a number of parts, but the assemblability at the time of combining the 1st housing 41 and the 2nd housing 42 will also be improved.

  In addition, you may change the door-check apparatus 100 of this embodiment as shown below.

  -As shown in FIG. 9, for example, the first housing 41 and the second housing 42 are coupled in a state where the tongue piece 423 of the second housing 42 is inserted into the first side wall 411 of the first housing 41. By doing this, the first housing 41 may be positioned inside the first housing 41 and the second housing 42 in the vertical direction. In this case, the first support portion S1 that contacts the elastic member 20 to support the elastic member 20 is formed in the first housing 41. In addition, a second support portion S2 that supports the first support portion S1 from the outside in the direction in which the elastic force of the elastic member 20 acts is formed in the second housing 42. Even in this case, the strength of the housing 40 with respect to the elastic force of the elastic member 20 can be improved by the action of the first support portion S1 and the second support portion S2 described above.

  The first housing 41 may be made of a metal material. Further, the second housing 42 may be made of a resin material. Even in this case, the stress received from the elastic member 20 is dispersed to both the first housing 41 and the second housing 42 by the first support portion S1 and the second support portion S2. The strong meshing of the housing 42 can make it difficult for the housing 40 to be deformed.

  The housing 40 may not have the holding portion 422. Further, in this case, a recess 42 b may be provided in a portion of the second housing 42 excluding the holding portion 422.

  The first housing 41 may be provided with a “recess” and the second housing 42 may be provided with a “convex”. However, particularly when the second housing 42 is made of a metal material, it is preferable to provide the recess 42 b in the second housing 42 because the recess 42 b can be formed by pressing together with the insertion hole 42 a.

  The first housing 41 may be fixed to the vehicle door 3.

  The first housing 41 and the second housing 42 may be coupled by means other than the concavo-convex engagement. For example, the first housing 41 and the second housing 42 may be coupled by a fastening member such as a bolt. Alternatively, the first housing 41 is provided with a projection (not shown) penetrating the second housing 42, and the projection (not shown) penetrating the second housing 42 is bent to provide the first housing 41 and the second housing. May be combined.

  The first support portion S1 may not be integrally formed with the first housing 41 or the second housing 42. For example, a plate member such as the tongue piece 423 may be separately manufactured and fixed to the second housing with an adhesive or fixed by fastening means such as a bolt.
