Description

  The present invention relates to a clip structure in which a pair of claws engage with a hole.

  Patent Document 1 discloses a clip structure (attachment structure) for attaching a holding body to a counterpart member without using a bolt or the like.

  In the clip structure, the mating member is provided with a locking hole, and the holding body is provided with a pair of projecting pieces.

  At the time of joining work for attaching the holding body to the mating member, the operator inserts the pair of projecting pieces into the locking holes while being elastically deformed so as to approach each other. At this time, the claw portion of the protruding piece extends beyond the locking hole, so that the claw portion of the protruding piece engages with the locking hole, and the protruding piece is coupled to the locking hole.

  On the other hand, at the time of separation work for removing the holding body from the mating member, the operator picks up the pair of projecting pieces and elastically deforms them so as to approach each other, thereby releasing the engagement of the claw portion with the locking hole. Thus, the protruding piece is extracted from the locking hole.

  However, for example, in the clip structure provided at the front part of the vehicle of the automobile, the separation work may be difficult when a space for the operator to insert his / her hand cannot be secured.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a clip structure that can be easily separated.

  According to an aspect of the present invention, a pair of claws engages with a hole, and the hole slides between the pair of engaging side portions respectively engaged with the claw and the pair of claws. There is provided a clip structure including a pair of guide sides that release the engagement between the engaging side and the claw by being elastically deformed so as to come into contact with each other.

  According to the above aspect, when the clip structure is separated, the pair of claws are elastically deformed while being in sliding contact with the pair of guide sides, and are released from the holes, thereby disengaging the engagement sides and the claws. Is done. Thus, in the clip structure, it is not necessary for the operator to pick the pair of claws and elastically deform them, so that the separation work is easily performed.

FIG. 1 is a perspective view showing a vehicle front portion according to the embodiment of the present invention. FIG. 2 is a perspective view of the clip structure. FIG. 3 is a cross-sectional view of the clip structure. FIG. 4 is a rear view of the clip structure. FIG. 5 is a rear view showing a modification of the clip structure. FIG. 6 is a rear view showing another modification of the clip structure.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, a frame 2 and a member 1 are provided in the front part of the engine room 3 of the vehicle. The frame 2 is a radiator core support that supports a radiator (not shown). A blower fan (not shown) is provided behind the frame body 2. The vehicle travel wind or forced wind sent by the blower fan passes through the radiator. The member 1 is an air guide (flow path member) that guides the air flow to the blower fan and the radiator. The frame 2 is a counterpart member to which the member 1 is attached.

  The member 1 abuts over the front surface 2B and the inner side surface 2C of the frame body 2 and is coupled to the frame body 2 by a plurality of (here, two) clip structures 30.

  When the vehicle travels, the member 1 receives wind pressure as shown by an arrow a in FIG. 1, but does not move with respect to the frame 2 by the front surface 2 </ b> B, the inner surface 2 </ b> C of the frame 2, and each clip structure 30. Supported.

  Hereinafter, the clip structure 30 will be described. FIG. 2 is a perspective view showing the clip structure 30. In addition, for simplification of description, the clip structure 30 is illustrated with a part thereof omitted.

  The clip structure 30 includes a pair of claws 10 (clips) provided in the member 1 and holes 20 provided in the frame body 2. The pair of claws 10 are integrally formed with the resin member 1.

  The hole 20 is formed such that its center O extends in the front-rear direction of the vehicle. Hereinafter, description will be made by setting three axes X, Y, and Z orthogonal to each other in each drawing. The Y-axis direction in which the center O of the hole 20 extends is referred to as “axial direction”, and the X-axis direction is referred to as “radial direction”.

  The hole 20 has a substantially elliptical inner periphery centered on the center O. The hole 20 is arranged so that the major axis of the ellipse extends in the left-right direction (X-axis direction) of the vehicle.

  The claw 10 protrudes from the attachment surface 1A of the member 1 in a beam shape. A gap 15 is formed between the pair of claws 10. The pair of claws 10 are formed symmetrically about the center O.

  The claw 10 extends from the mounting surface 1A of the member 1 in a beam shape, a stepped portion 12 protruding with a step on the outer surface 14 (upper surface or lower surface) of the protruding portion 11, and extends from the stepped portion 12 to the tip. And an existing tapered tip portion 13. The step portion 12 is formed in a planar shape substantially orthogonal to the outer surface 14 of the protruding portion 11.

  At the time of attaching the member 1 to the frame body 2, the member 1 is moved in the Y-axis direction (rear side of the vehicle), and each tip portion 13 is inserted into the hole 20. At the time of this insertion, each tip 13 slides on the inner periphery of the hole 20 and elastically deforms the claws 10 so as to approach each other. As shown by solid lines in FIGS. 3 and 4, when each tip portion 13 is inserted beyond the hole 20, each claw 10 expands, and the stepped portion 12 becomes the opening edge 2 </ b> A of the hole 20 (the back surface of the frame 2). ). Thus, the claw 10 is engaged with the hole 20 so that the member 1 is fixed so as not to be separated from the frame 2.

  As shown in FIG. 4, the hole 20 has an inner periphery extending along a substantially elliptical shape. The inner periphery of the hole 20 has a pair of engaging side portions 21 that face each other and two pairs of guide side portions 22 that are connected to the pair of engaging side portions 21. As will be described later, the pair of engagement side portions 21 are provided in a retaining region 25 located at the center of the hole 20. The two pairs of guide sides 22 are provided in release areas 26 located at both ends of the hole 20.

  The pair of engagement side portions 21 extend substantially parallel to each other along the X axis. The pair of engagement side portions 21 are formed symmetrically with respect to the center O.

  The two pairs of guide side portions 22 are inclined with respect to the X axis and extend so as to gradually reduce the opening width (the length in the Z axis direction) of the hole 20 in the X axis direction.

  As shown by solid lines in FIGS. 3 and 4, when the member 1 is fixed to the frame body 2, the tip 13 of the claw 10 is located in the retaining region 25 in the center of the hole 20, and the step 12 The entire region comes into contact with the opening edge 2A of the hole 20. Thereby, in the nail | claw 10, reaction force arises in the level | step-difference part 12 with respect to the external force which acts in the direction which pulls out from the hole 20 (left direction about Y-axis in FIG. 3), and displacement to the axial direction of the hole 20 is controlled. The

  When removing the member 1 from the frame 2, first, as shown by arrows b in FIG. 1 and FIG. 4, the member 1 is moved in the radial direction of the hole 20 with respect to the frame 2 (leftward with respect to the X axis in FIG. 4). ). As a result of this movement, the outer surface 14 of each protrusion 11 is brought into sliding contact with the guide side 22 (inner circumference) of the hole 20, so that each claw 10 is elastically deformed as shown by a two-dot chain line in FIGS. 3 and 4. Approaching each other, the gap 15 is reduced.

  Thus, when the pair of claws 10 move to the release region 26 of the hole 20, an opening edge in which a part of the step portion 12 is connected to the guide side portion 22 of the hole 20 as shown by a two-dot chain line in FIGS. 3 and 4. The most part of the stepped portion 12 is separated from the opening edge 2 </ b> A of the hole 20 and faces the internal space of the hole 20. In this state, the member 1 is moved in the Y-axis direction (front of the vehicle) as indicated by an arrow c in FIG. 1 while slightly rotating around the Z-axis with respect to the frame 2. At this time, the claw 10 comes out of the hole 20 while the outer periphery of the tip end part 13 is in sliding contact with the guide side part 22 (inner periphery of the hole 20) of the hole 20 to reduce the gap 15 and approach each other. Thus, the claw 10 is elastically deformed, whereby the member 1 is smoothly removed from the frame 2.

  Next, the effect of this embodiment will be described.

  According to the present embodiment, the clip structure 30 has the pair of claws 10 engaged with the holes 20. The holes 20 are formed between a pair of engagement side portions 21 that respectively engage with the pair of claws 10 and elastically deformed so that the pair of claws 10 are brought into sliding contact with each other so as to approach each other. And a pair of guide side portions 22 for releasing the engagement.

  With this configuration, when the clip structure 30 is separated, the pair of claws 10 are elastically deformed while slidably contacting the guide side portion 22 of the hole 20 and are released from the hole 20. Is disengaged. Thus, in the clip structure 30, it is not necessary for the operator to pick and elastically deform the pair of claws 10, and the separation work for extracting the claws 10 from the holes 20 is easily performed.

  Further, the pair of engagement side portions 21 extend opposite to each other. The pair of guide side portions 22 are connected to the pair of engagement side portions 21 to reduce the opening width of the hole 20.

  With this configuration, when the operator slides the member 1 with respect to the frame body 2 at the time of separation work, the pair of claws 10 are slidably brought into contact with the pair of guide side portions 22 so as to approach each other. It is deformed and the engagement with the engagement side portion 21 is released.

  In the vehicle front part of the automobile, when the member 1 (air guide) is removed from the frame 2 (radiator core support), a space for the operator to insert his / her hand may not be secured. In this case, in the conventional clip structure, since the operator cannot perform the separation work of picking up the nail and extracting it from the hole, it is necessary to remove the frame body 2 and the like from the vehicle body.

  On the other hand, in the clip structure 30 of the present embodiment, the operator removes the member 1 from the frame 2 by holding the member 1 from the front of the vehicle and sliding it with respect to the frame 2 as described above. Can do. Therefore, it becomes unnecessary to remove the frame body 2 from the vehicle body, and the work of removing the member 1 is performed efficiently.

  In addition, the hole 20 has a configuration in which two pairs of guide sides 22 extend from both ends of the pair of engagement sides 21.

  With this configuration, depending on the shape of the frame 2, when removing the member 1 during the separation work, the sliding direction for moving the member 1 relative to the frame 2 can be selected from two directions (the left and right directions of the vehicle). .

  In addition, the opening shape of the hole 20 is not limited to the above-described substantially elliptical shape, and may be an oval shape, a substantially oval shape having a linear portion on a part of the inner periphery, or a substantially polygonal shape.

  Next, a modification of the clip structure 30 shown in FIG. 5 will be described.

  The opening shape of the hole 20 is formed in a substantially semi-elliptical shape in which one side of the elliptical shape is deleted. The inner circumference of the hole 20 is substantially orthogonal to the pair of engaging side portions 21, the pair of guide side portions 22 that are connected to one end side of the engaging side portion 21, and the other end of the engaging side portion 21. And a regulating side portion 23 to be used.

  In this case, the member 1 is supported so that a reaction force is generated at a portion where the claw 10 abuts against the restriction side portion 23 of the hole 20 due to wind pressure received during traveling of the vehicle, and the member 1 does not move with respect to the frame body 2.

  When the member 1 is detached from the frame 2, the member 1 is moved in the radial direction of the hole 20 (the direction opposite to the direction in which the wind pressure acts) with respect to the frame 2 as indicated by arrows in FIG. 5. By this movement, each claw 10 is elastically deformed as shown by a two-dot chain line in FIG. 5, so that the member 1 is smoothly removed from the frame body 2.

  According to this modification, the hole 20 has a guide side portion 22 extending from one end of the engagement side portion 21, and a restriction side portion 23 that restricts relative movement of the claw 10 from the other end of the engagement side portion 21. An extended clip structure 30 can be provided.

  With this configuration, the claw 10 abuts against the restriction side 23, and thus the relative movement toward the restriction side 23 in the direction substantially parallel to the engagement side 21 is restricted. This prevents the claw 10 from coming out of the hole 20 when the claw 10 receives an external force on the regulating side 23 side.

  Further, the claw 10 is provided on the member 1 (flow path member) that receives wind pressure in the vehicle, and the regulating side portion 23 is disposed on the side where the member 1 is about to move by receiving the wind pressure with respect to the engaging side portion 21. Clip structure 30 can be provided.

  With this configuration, when the member 1 attempts to move under wind pressure, the claw 10 comes into contact with the restriction side portion 23. As a result, the claw 10 is prevented from moving and coming out of the hole 20, and the member 1 is fixed so as not to move.

  Next, a modification of the clip structure 30 shown in FIG. 6 will be described.

  The inner periphery of the hole 20 has an inner peripheral portion 20A having a substantially elliptical shape at the upper portion and an inner peripheral portion 20B having a lower straight shape.

  The upper inner peripheral portion 20 </ b> A includes a central engagement side portion 21 and two guide side portions 22 that extend in a connected manner to both end sides of the engagement side portion 21. Each guide side portion 22 having a substantially elliptic arc shape gradually decreases as the radius of curvature of the curved surface increases from the left and right sides of the engagement side portion 21.

  The lower inner peripheral portion 20 </ b> B includes a central engagement side portion 31 and two guide side portions 32 that extend in a connected manner to both end sides of the engagement side portion 31. Each guide side 32 extends in a straight line extending from the engagement side 31.

  Also in this case, the pair of guide side portions 22 and 32 arranged in the vertical direction extend so as to gradually reduce the opening width (length in the Z-axis direction) of the hole 20 in the X-axis direction.

  In a state where the member 1 is fixed to the frame body 2, the entire area of the stepped portion 12 of each claw 10 abuts against the opening edge 2 </ b> A of the hole 20 as indicated by a solid line in FIG. 6. Thereby, each claw 10 is restricted from being displaced in the axial direction of the hole 20.

  When removing the member 1 from the frame 2, first, the member 1 is moved leftward about the X axis as shown by an arrow b in FIG. By this movement, the upper claw 10 comes into sliding contact with the guide side portion 22 of the inner peripheral portion 20A, so that each claw 10 is elastically deformed as shown by a two-dot chain line and approaches each other, and the gap 15 is reduced.

  Thus, when the upper claw 10 moves, most of the stepped portion 12 is detached from the opening edge 2A of the hole 20 and faces the internal space of the hole 20. In this state, the member 1 is slightly rotated about the Z axis with respect to the frame body 2 and moved in the Y axis direction (front of the vehicle) while rotating downward about the X axis. At this time, the lower claw 10 rotates around the X axis, so that the stepped portion 12 is detached from the opening edge 2A of the hole 20. The upper claw 10 comes out of the hole 20 while reducing the gap 15 by the outer periphery of the tip end portion 13 being in sliding contact with the guide side portion 22 of the inner peripheral portion 20A. Thus, the claw 10 is elastically deformed, whereby the member 1 is smoothly removed from the frame 2.

  In FIG. 1, the two clip structures 30 are arranged so as to be aligned in the Z-axis direction (vertical direction). On the other hand, in this modification, the two clip structures 30 are arranged so as to be aligned in the X-axis direction (left-right direction). Thereby, as described above, the member 1 can be rotated about the X axis (up and down direction) with respect to the frame body 2.

  Further, in the clip structure 30 shown in FIG. 6, the opening shape of the hole 20 may be reversed in the vertical direction.

  The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment. Absent.

  Although this invention is suitable as a clip structure which attaches an air guide to a vehicle, it is not restricted to this, It can apply also to the other member attached to a vehicle. Moreover, it is applicable also to the apparatus and installation used other than a vehicle.
