Description

Technical Field

[0001] The present invention relates to a hinge structure and a clip having the hinge structure. Background Art

[0002] Generally, when fixing a bus bar or the like as a mounting component to an automotive body or the like as a component to be mounted, after inserting a clip into a support bar provided on the automotive body or the like and fixing it, the bus bar or the like is then mounted and fixed to the clip.

[0003] In this way, a clip having a hinge structure as disclosed in Patent Document 1 is provided. When mounting a bus bar or the like on the clip, it is preferable to be able to hold the lid of the clip in a state of being open with respect to the main body of the clip, so that the bus bar or the like does not interfere with the lid of the clip and is easily mounted.

[0004] However, for example, when the support bar for inserting and fixing the clip is provided in a narrow position, i.e., a narrow part, inside the automotive body or the like, when mounting a bus bar or the like on the clip fixed in such a part, there is a case where the lid of the clip interferes with peripheral components or the like, making it difficult to hold the lid of the clip in a state of being open with respect to the main body of the clip. In such a case, if the operator does not hold the lid of the clip by hand to keep it open with respect to the main body, the lid of the clip may close due to its own weight, making it difficult to mount the bus bar or the like. Also, even if the operator holds the lid of the clip by hand to keep it open with respect to the main body, as described above, when the clip is fixed in a narrow part, it is difficult for the operator's hand to enter such a part. And when the clip is fixed at multiple points, it is impossible for the operator to hold the lids of all the clips open with both hands at the same time. In addition, when performing an operation of temporarily removing a bus bar or the like from the clip and then remounting it to the clip for maintenance or other purposes, after releasing the engagement between the lid and the main body of the clip, it is necessary to hold the lid of the clip in a state of being open with respect to the main body of the clip.

[0005] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2018 - 71647 Summary of the Invention

[0006] Technical Problem to be Solved by the Invention

[0007] In view of the above situation, the technical problem to be solved by the present invention is to provide a hinge structure and a clip having the hinge structure that can hold the lid of the clip in a state of being open with respect to the clip main body in a narrow part.

[0008] The present invention is made to solve the above technical problems. A hinge structure in an embodiment of the present invention is used to rotatably couple a main body and a lid, and is characterized in that

[0009] At least a part of the axis of the hinge has a pin and a socket.

[0010] The pin has an interference portion including a long side and a short side.

[0011] The socket includes a hole portion. The hole portion includes a long side and a short side, and surrounds the interference portion of the pin. The short side is shorter than the long side of the pin, and the long side includes a concave portion.

[0012] Via the hinge structure, the lid can be opened and closed relative to the main body. When the lid is opened upright relative to the main body, the short side of the interference portion of the pin is inserted into the concave portion of the hole portion of the socket, so that the lid can be held in a state upright relative to the main body.

[0013] Moreover, in the hinge structure in another embodiment, the interference portion and the hole portion may be elliptical in shape.

[0014] Moreover, in the hinge structure in another embodiment, the socket may further have a first restricting surface and a second restricting surface. When the lid is closed relative to the main body, the first restricting surface abuts against the surface on the long side of the interference portion of the pin, restricting the movement of the surface on the long side of the interference portion of the pin in a first direction pressing against the first restricting surface within the hole portion, and the second restricting surface abuts against the surface on the short side of the interference portion of the pin, restricting the movement of the surface on the short side of the interference portion of the pin in a second direction pressing against the second restricting surface within the hole portion, thereby restricting the movement of the lid.

[0015] Moreover, in the hinge structure in another embodiment, the lid may further have a third restricting surface and a fourth restricting surface.

[0016] When the lid is closed relative to the main body, the third restricting surface abuts against the main body, restricting the movement of the third restricting surface in a third direction opposite to the first direction pressing against the main body, and the fourth restricting surface abuts against the main body, restricting the movement of the fourth restricting surface in a fourth direction opposite to the second direction pressing against the main body, thereby restricting the movement of the lid.

[0017] Moreover, a clip in an embodiment of the present invention is a clip having the hinge structure of any embodiment of the present invention.

[0018] Effects of the Invention

[0019] According to the hinge structure of the present invention, the lid of the clip can be held in a state opened relative to the clip main body at a narrow portion. Brief Description of the Drawings

[0055] Hereinafter, with reference to the drawings, the hinge structure of the embodiment of the present invention will be described.

[0056] Figure 1 FIG. is a perspective view of the clip 10 showing the state where the lid 30 of the embodiment of the present invention is opened 180° as viewed from above. The clip 10 is made of resin, for example. The clip 10 includes a main body 20 and a lid 30. The main body 20 and the lid 30 are rotatably coupled by a hinge 40. The lid 30 rotates via the hinge structure and can be opened and closed relative to the main body 20. The main body 20 can hold the bus bar 61 which will be described later in Figure 7 In the following description. In the present embodiment, the main body 20 has two receiving portions 22 so as to be able to hold two bus bars. The main body 20 includes a lid locking claw receiving portion 21. In the present embodiment, the lid locking claw receiving portion 21 includes a protrusion. The lid 30 includes a lid locking claw 31. In the present embodiment, the lid locking claw 31 includes a protrusion. In the present embodiment, as described later, the lid 30 rotates relative to the main body 20 via the hinge 40. When the lid 30 is in a closed state relative to the main body 20, the protrusion of the lid locking claw 31 and the protrusion of the lid locking claw receiving portion 21 are engaged with each other. By the mutual locking of the lid locking claw 31 and the lid locking claw receiving portion 21, the lid 30 can be held in a closed state relative to the main body 20.

[0057] Figure 2The perspective view shows the clip 10 in a state where the cover 30 of the embodiment of the present invention is opened 180° as viewed from below. The clip 10 includes a support bar holding portion 50. In the support bar holding portion 50, there are provided a support bar holding piece 51, a support bar insertion hole 52, and a support bar locking claw 53. Regarding the support bar locking claw 53, refer to Figure 4 simultaneously, it can be seen that the support bar locking claw 53 is provided in the support bar holding portion 50. As described later, the support bar 60 is inserted into the support bar insertion hole 52 of the support bar holding piece.

[0058] Figure 3 The left side view shows the clip 10 in a state where the cover 30 of the embodiment of the present invention is opened 180°. It should be noted that in this embodiment, the right side view of the clip 10 has a shape symmetrical to the left side view, so it is omitted. The axis of the hinge 40 extends in the Y-axis direction, and at least a part of this axis of the hinge 40 has a pin 41 and a socket 43. In this embodiment, the pin 41 and the socket 43 are respectively provided at two positions at one end and the other end of the axis of the hinge 40. Figure 3 The one end side is shown. It should be noted that the positions where the pin 41 and the socket 43 are provided are not limited to this. For example, the pin 41 and the socket 43 can be provided only at one position at one end of the axis of the hinge 40. The pin 41 has an interference portion 42. The interference portion 42 includes a long side along the X-axis direction and a short side along the Z-axis direction in the XZ plane. In this embodiment, the interference portion 42 is elliptical in the XZ plane. The socket 43 includes a hole portion 44. In this embodiment, the hole portion 44 includes a long side along the X-axis direction and a short side along the Z-axis direction in the XZ plane. The hole portion 44 is provided so as to surround the interference portion 42 of the pin 41, and the short side of the hole portion 44 is set to be shorter than the long side of the interference portion 42. In this embodiment, the interference portion 42 is elliptical in the XZ plane. And, in this embodiment, the long side of the hole portion 44 includes recesses 45 at two positions. The hole portion 44 of the socket 43 includes a first restricting surface 46 and a second restricting surface 47.

[0059] Figure 4 The sectional view shows Figure 1 the sectional view taken along the line A - A shown. As described above, the support bar locking claw 53 is provided in the support bar holding portion 50. The support bar locking claw 53 engages with the support bar 60 inserted into the support bar insertion hole 52 and holds the support bar 60 within the support bar holding piece 51. The cover 30 includes a third restricting surface 48 and a fourth restricting surface 49.

[0060] Figure 5 The perspective view shows the clip 10 in a state where the cover 30 of the embodiment of the present invention is opened 90° as viewed from below. The state of opening the cover 30 by 90° means the state of opening the cover 30 by 180°, that is Figure 1The state where the cover 30 is rotated 90° relative to the main body 20 via the hinge 40. In such a state where the cover 30 is opened 90°, as shown by the dotted line, in the Z-axis direction, the support bar 60 is inserted into the support bar insertion hole 52. In the present embodiment, when the support bar 60 is inserted into the support bar insertion hole 52, since the support bar locking claw 53 is hooked on the hole provided in the support bar 60, the support bar 60 is locked. In this way, the support bar 60 is locked by the support bar locking claw 53, and the support bar 60 can be held within the support bar holding piece 51.

[0061] Figure 6 The left side view of the clip 10 showing the state where the cover 30 of the embodiment of the present invention is opened 90°. It should be noted that, Figure 3 the same as, in the present embodiment, the right side view of the clip 10 is a shape symmetric to the left side view, so it is omitted. For the hinge 40, the Figure 6 showing the state where the cover 30 is opened 90° and the Figure 3 showing the state where the cover 30 is opened 180° are compared and described in detail.

[0062] As described above, in the present embodiment, the pin 41 and the socket 43 are respectively provided at two positions at one end and the other end of the axis of the hinge 40. Figure 6 Showing one end side. The long side of the interference portion 42 is in the XZ plane and extends in the Figure 3 X-axis direction, and extends in the Figure 6 Z-axis direction as the cover 30 rotates 90° relative to the main body 20. Similarly, the short side of the interference portion 42 is in the XZ plane and extends in the Figure 3 Z-axis direction, and as the cover 30 rotates 90° relative to the main body 20, the interference portion 42 also rotates 90° and extends in the Figure 6 X-axis direction. At this time, the short sides of the two portions of the interference portion 42 are respectively inserted into the concave portions 45 of the two portions of the hole portion 44 of the socket 43. This is because the short side of the hole portion 44 is set to be shorter than the long side of the interference portion 42, so the short side of the interference portion 42 is inserted into the concave portion 45. By inserting the short side of the interference portion 42 into the concave portion 45, as Figure 6 shown, the cover 30 can be held in a state of being opened 90° relative to the main body 20.

[0063] Figure 7 Shows the form in which the bus bar 61 is installed on the clip 10 in the state where the clip is fixed to the support bar 60 provided in the narrow portion formed by the wall 62 in the embodiment of the present invention. As described above, the bus bar 61 can be held in the accommodation portion 22 of the main body 20 of the clip 10. In Figure 7In the state of , the cover 30 can maintain a state of being opened 90° relative to the main body 20. In this way, by maintaining the state of the cover 30 being opened 90° relative to the main body 20, for example, the cover 30 will not close due to the interference between the cover 30 and the wall 62 or the self-weight of the cover 30. Therefore, the bus bar 61 will not interfere with the cover 30, and the bus bar 61 can be smoothly installed in the accommodating portion 22. It should be noted that the "state of being opened 90°" of the cover 30 relative to the main body 20 can be a "standing open state" where the cover 30 does not interfere with the wall 62 and the bus bar 61 relative to the main body 20, and it does not have to be strictly 90°.

[0064] Figure 8 It shows the state in the embodiment of the present invention where the bus bar 61 is installed in the clip 10 and the cover 30 is closed. After the bus bar 61 is arranged in the accommodating portion 22 of the main body 20 of the clip 10, the cover 30 is closed relative to the main body 20. At this time, however, the protrusion of the cover locking claw 31 of the cover 30 engages with the protrusion of the cover locking claw receiving portion 21 of the main body 20. By locking the cover locking claw 31 and the cover locking claw receiving portion 21, the cover 30 can maintain a state of being closed relative to the main body 20, and further, the clip 10 is in a state of holding the bus bar 61.

[0065] Here, in a clip manufactured by integrally molding in a state where a pin and a socket are combined in one mold, due to the structure of the mold, there is a certain degree of gap between the pin and the socket. In such a conventional clip with a gap between the main body and the cover, when the bus bar is arranged in the accommodating portion of the main body and the cover is closed, due to such a gap, the bus bar will shake within the clip. Against this background, a clip with less shaking of the cover is required.

[0066] Figure 9 It shows Figure 8 A cross-sectional view taken along the line B - B shown. In the present embodiment, the socket 43 also has a first limiting surface 46 and a second limiting surface 47 in the hole portion 44. When the cover 30 is closed relative to the main body 20, the first limiting surface 46 abuts against the long side surface of the interference portion 42 of the pin 41, and in the hole portion 44, the movement of the long side surface of the interference portion 42 of the pin 41 in the direction pressing against the first limiting surface 46, that is, the a direction, is restricted. And the second limiting surface 47 abuts against the short side surface of the interference portion 42 of the pin 41, and in the hole portion 44, the movement of the short side surface of the interference portion 42 of the pin 41 in the direction pressing against the second limiting surface 47, that is, the b direction, is restricted. In this way, by restricting the movement of the interference portion 42 of the pin 41 in the a direction and the b direction, the movement of the cover 30 in the a direction and the b direction can be restricted. Therefore, by providing such a structure in the hole portion 44 of the socket 43, the shaking of the cover 30 can be suppressed.

[0067] And Figure 10representation Figure 8 A cross-sectional view taken along line C-C shown in the figure Figure 11 representation Figure 8 A cross-sectional view taken along line D-D shown in the figure. In the present embodiment, the lid 30 further has a third restricting surface 48 and a fourth restricting surface 49. Similarly, when the lid 30 is closed relative to the main body 20, the third restricting surface 48 abuts against the main body 20, restricting the movement of the third restricting surface 48 in the direction of pressing against the main body 20, i.e., the c-direction. In the present embodiment, the c-direction and the a-direction are opposite directions. Also, the fourth restricting surface 49 abuts against the main body 20, restricting the movement of the fourth restricting surface 49 in the direction of pressing against the main body 20, i.e., the d-direction. In the present embodiment, the d-direction and the b-direction are opposite directions. Thus, by restricting the movement of the third restricting surface 48 of the lid 30 in the c-direction and the movement of the fourth restricting surface 49 of the lid 30 in the d-direction, the movement of the lid 30 in the c-direction and the d-direction can be restricted. Therefore, in addition to the structure of the hole portion 44 of the socket 43 that restricts the movement of the lid 30 in the a-direction and the b-direction as described above, by providing such a structure on the lid 30, the wobbling of the lid 30 can be further suppressed.

[0068] As described above, the embodiments of the present invention have been described with reference to the drawings. As long as the hinge structure is configured to hold the lid in an open state relative to the main body, it is not limited to the specific structures described, and modifications can be appropriately made.

[0069] For example, in other embodiments, as long as either the pin or the socket is an elastic piece and this piece can elastically flex non-destructively to insert the pin into the socket, the lid and the main body of the clip can also be manufactured not integrally formed but using separate molds to be an assembled type.

[0070] And, for example, in order to further increase the holding strength when holding the lid in a state of being opened 90° relative to the main body, it can be appropriately changed by setting a larger ratio of the length of the long side to the length of the short side of the interference portion of the pin, setting a deeper depth of the concave portion of the hole portion of the socket, setting a narrower width, making the pin a harder material than the socket, etc., so that the long side of the interference portion of the pin is more deeply embedded in the concave portion of the hole portion of the socket.

[0071] In addition, the application of the hinge structure of the present invention is not limited to the support bar being inserted into the clip as described with reference to the drawings above. For example, it can also be appropriately applied to a structure by snap fit, that is, a snap fit for firmly holding, an anchor foot holding for fitting into a registration hole, a two-component holding for fitting with other clips in the shape of a doghouse, etc.

[0072] Moreover, the process of installing the mounting component is not limited to the process of fixing the clip to the support bar in advance as described with reference to the drawings above, and then installing the mounting component on the clip and closing the cover to fix the mounting component. For example, the clip can also be installed on the mounting component in advance and the cover can be closed, and then the mounting component can be fixed by fixing the clip.

[0073] It should be noted that for the present invention, embodiments are illustrated and described, but the application object of the present invention is not limited to, for example, the application to automobiles, and can also be the application to various products, and can be appropriately applied within the scope not departing from the technical idea of the invention.
