[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-98806 Summary of the Invention [Problem to be solved by the invention]

[0004] The locking mechanism switches the lid between locked and unlocked states, for example, by restricting the operation of a push lifter that pushes the lid open from the inside to the outside. The push lifter has a hole through which a locking member is inserted and removed. The push lifter also has a built-in compression spring. When the locking member is removed from the hole, the compression spring expands, causing the push lifter to move toward the lid and open it. When a user pushes the lid from the outside to close it, the push lifter retracts against the compression spring and moves away from the lid, inserting the locking member into the hole. When the locking member is inserted into the hole, the push lifter is retracted from the lid, preventing the lid from opening. The locking member is driven by a motor in conjunction with the opening and closing of the vehicle door using, for example, a smart key. The motor has multiple terminals attached. Each terminal is located in a predetermined position, and short-circuiting between adjacent terminals must be prevented.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a lid locking structure that can easily position a plurality of terminals connected to a motor that is a drive source for locking and unlocking the lid. [Means for solving the problem]

[0006] A lid locking structure according to one aspect of the present invention comprises: The vehicle is provided with a locking mechanism that switches between locking and unlocking a lid that freely opens and closes an opening provided in a body panel. The locking mechanism is a motor that is a drive source for locking and unlocking the lid; a plurality of terminals including a first terminal and a second terminal connected to the motor; a case that houses the motor and the plurality of terminals, The second terminal is a lead portion located near the motor and arranged laterally and spaced apart from the first terminal; a tip portion located away from the motor and arranged vertically above the first terminal with a space therebetween; a bent portion bent between the lead portion and the tip portion in a direction approaching the first terminal, The case has a support surface that supports the lower surface of the bent portion. [Effects of the Invention]

[0007] In the lid locking structure of the present invention, although the tip of the second terminal is arranged vertically above the first terminal, the bent portion of the second terminal is supported by the case, so that the second terminal is positioned so as not to sag under its own weight. Because the second terminal is supported by the case, a gap is provided between the first terminal and the second terminal, preventing contact between the first terminal and the second terminal.

[0008] The lid locking structure of the present invention has a bent portion on the second terminal arranged above, and a support surface for the bent portion is provided on the case, and can be realized by simply modifying both the existing terminal and the case. Therefore, the lid locking structure of the present invention prevents increases in cost, significant increases in weight, and decreases in productivity. [Brief explanation of the drawings]

[0010] Specific examples of the lid locking structure of the present invention will be described with reference to the drawings. The same reference numerals in the drawings indicate the same items. For the sake of convenience, some components may be exaggerated or simplified in the drawings. The dimensional proportions of the various components in the drawings may also differ from the actual proportions.

[0011] <Summary> As shown in FIG. 1, the lid locking structure 1 includes a locking mechanism 3. The locking mechanism 3 switches between locking and unlocking the lid 2. The lid 2 covers an opening provided in a vehicle body panel (not shown) so as to be freely opened and closed. In this example, the opening is an opening for inserting a fuel nozzle or an opening for inserting a charging connector. The lid 2 is made of, for example, a plate material. The shape of the plate material is, for example, circular, rectangular, or elliptical. The lid 2 is rotatably supported on the vehicle body by a hinge (not shown). An edge of the lid 2 facing the hinge is adjacent to the tip of a push lifter 7. The edge of the lid 2 moves in an arc-shaped path around the hinge as an axis to open and close the lid 2. The locking mechanism 3 includes a motor 4, a plurality of terminals 5, and a case 6.

[0012] <Motor> The motor 4 is a drive source for locking and unlocking the lid 2 shown in FIG. 1. The lid 2 is locked and unlocked by restricting the operation of the push lifter 7, which pushes the lid 2 open from the inside to the outside. The push lifter 7 has a built-in compression spring (not shown). This compression spring causes the push lifter 7 to move forward toward the lid 2 and backward away from the lid 2. The push lifter 7 has a hole 7h through which a locking member 8 is inserted and removed. The motor 4 operates the locking member 8.

[0013] As shown in FIG. 1, a transmission mechanism 9 is connected to the motor 4. In this example, the transmission mechanism 9 includes a worm having spiral teeth on the outer peripheral surface of a cylindrical body, and a slider having internal teeth that fit onto the teeth of the worm. The worm is attached to the rotating shaft of the motor 4 and is driven to rotate by the motor 4. The slider is held in the case 6 so as not to rotate with the worm. The slider advances and retreats in the axial direction of the worm as the worm rotates. A locking member 8 is attached to the slider so as to be parallel to the worm. The locking member 8 is a rod-shaped member that advances and retreats relative to the hole 7h of the push lifter 7 as driven by the motor 4 via the transmission mechanism 9. The motor 4 is driven in conjunction with, for example, the opening and closing of a vehicle door using a smart key.

[0014] To unlock the lid 2 from a closed state, the motor 4 is driven in conjunction with the vehicle door opening operation, and the locking member 8 is removed from the hole 7h of the push lifter 7. When the locking member 8 is removed from the hole 7h, the compression spring built into the push lifter 7 expands, and the push lifter 7 moves toward the lid 2, pushing the lid 2 from the inside outward, allowing the lid 2 to be opened.

[0015] To lock the lid 2 in the closed position from an open state, the user presses the lid 2 from the outside, and the push lifter 7 is pushed by the lid 2 and moves back in a direction away from the lid 2 against the compression spring. Furthermore, the motor 4 is driven in conjunction with the closing operation of the vehicle door, and the locking member 8 is inserted into the hole 7h of the push lifter 7. With the locking member 8 inserted into the hole 7h, the push lifter 7 is fixed in a position retracted from the lid 2 and does not move toward the lid 2.

[0016] <Terminal> As shown in FIG. 1, a plurality of terminals 5 are connected to the motor 4. The plurality of terminals 5 include a first terminal 51 and a second terminal 52. The first terminal 51 and the second terminal 52 are adjacent to each other. One of the features of the lid lock structure 1 of the embodiment is that the first terminal 51 and the second terminal 52 have portions arranged horizontally and vertically with a gap between them, as shown in FIGS. 2 to 4. "Horizontally arranged" means that the plane extending from the bottom surface 60m of the storage recess 60 of the case 6 shown in FIGS. 2 and 5 is used as a reference plane, and the terminals are arranged in a direction along this reference plane. "Vertically arranged" means that the terminals are arranged in a direction perpendicular to the reference plane. For ease of explanation, the motor 4 is not shown in FIGS. 2 and 5.

[0017] ≪First terminal≫ The first terminal 51 is a rod-shaped piece having a bent portion. As shown in Figures 3 and 4, the first terminal 51 includes a first base end portion 511, a first lead portion 512, a first tip end portion 513, and a first bent portion 514. The first terminal 51 further includes a base-side bent portion 515. The first terminal 51 in this example is a rectangular wire.

[0018] The first base end 511 is a portion connected to the motor 4. In this example, the first base end 511 is aligned in series with the second terminal 52. In this example, the first base end 511 extends in a direction that intersects the reference plane, in this example, perpendicular to the reference plane. The first terminal 51 transitions, by a base-side bent portion 515, from the first base end 511 aligned in series with the second terminal 52 to the first lead portion 512 aligned horizontally with the second terminal 52.

[0019] The first lead portion 512 is a portion arranged side by side with a gap between them on the side of the second terminal 52. In this example, the first lead portion 512 includes a horizontal portion 512h and a vertical portion 512v. The horizontal portion 512h extends parallel to the reference plane. In this example, the horizontal portion 512h is arranged so that the surface of the horizontal portion 512h along the long side of the cross section of the rectangular wire faces the reference plane. The horizontal portion 512h is arranged along the top surface of the motor 4 (FIG. 1) and the top surface of the wall portion 61 (FIG. 2) of the case 6 (described later). The vertical portion 512v extends in a direction that intersects with the horizontal portion 512h, in this example, perpendicular to the horizontal portion 512h. In this example, the vertical portion 512v is bent flatwise with respect to the horizontal portion 512h. Flatwise bending refers to bending the rectangular wire so that the surface along the long side of the cross section faces inward. The vertical portion 512v is arranged along the side surface of the wall portion 61 (FIG. 2).

[0020] The first tip portion 513 is a portion arranged vertically below the second terminal 52 with a gap therebetween. In this example, the first tip portion 513 is arranged so that the surface along the short side of the cross section of the rectangular wire faces the reference plane. The first tip portion 513 is connected to a power source (not shown). The first tip portion 513 is located closer to the bottom surface of the case 6 than the second terminal 52. A step portion 513s is provided on the underside of the first tip portion 513. The underside of the first tip portion 513 faces the bottom surface of the case 6. In this example, the step portion 513s is located closer to the first lead portion 512 than the longitudinal center of the first tip portion 513. In this example, the step portion 513s is located so that the underside of the first tip portion 513 facing the first lead portion 512 is located lower, and the underside of the tip side of the first tip portion 513 is located upper.

[0021] The first bent portion 514 is provided between the first lead portion 512 and the first tip portion 513. The first bent portion 514 is a transition portion from the first lead portion 512, which is aligned horizontally with the second terminal 52, to the first tip portion 513, which is aligned vertically with the second terminal 52. The first bent portion 514 is bent in a direction from the first lead portion 512 toward the second terminal 52, and is bent so that the first tip portion 513 is positioned below the second terminal 52. In this example, the first bent portion 514 is bent edgewise with respect to the vertical portion 512v of the first lead portion 512, and then bent flatwise. Edgewise bending is bending a rectangular wire with the surface along the short side of its cross section facing inward.

[0022] ≪Second terminal≫ The second terminal 52 is a rod-shaped piece having a bent portion. As shown in Figures 3 and 4, the second terminal 52 includes a second base end portion 521, a second lead portion 522, a second tip end portion 523, and a second bent portion 524. The second terminal 52 in this example is a rectangular wire.

[0023] The second base end portion 521 is a portion connected to the motor 4. In this example, the second base end portion 521 extends in a direction that intersects with the reference plane, in this example, perpendicular to the reference plane.

[0024] The second lead portion 522 is a portion arranged side by side with a gap between them on the side of the first terminal 51. In this example, the second lead portion 522 includes a horizontal portion 522h and a vertical portion 522v. The horizontal portion 522h extends in a direction parallel to the reference plane. In this example, the horizontal portion 522h is arranged so that the surface along the long side of the cross section of the rectangular wire faces the reference plane. In this example, the horizontal portion 522h is bent flatwise relative to the second base end portion 521. The horizontal portion 522h is arranged along the top surface of the motor 4 (FIG. 1) and the top surface of a wall portion 61 (FIG. 2) of the case 6, which will be described later. The vertical portion 522v extends in a direction that intersects with the horizontal portion 522h, in this example, perpendicular to it. In this example, the vertical portion 522v is bent flatwise relative to the horizontal portion 522h. The vertical portion 522v is arranged along the side surface of the wall portion 61 (FIG. 2).

[0025] The second tip portion 523 is a portion arranged vertically above the first terminal 51 with a gap therebetween. In this example, the second tip portion 523 is arranged so that the surface along the short side of the cross section of the rectangular wire faces the reference plane. The second tip portion 523 is connected to a power source (not shown). The second tip portion 523 is located farther from the bottom surface of the case 6 than the first terminal 51.

[0026] The second bent portion 524 is provided between the second lead portion 522 and the second tip portion 523. The second bent portion 524 is a portion that transitions from the second lead portion 522, which is aligned horizontally with the first terminal 51, to the second tip portion 523, which is aligned vertically with the first terminal 51. The second bent portion 524 is bent in a direction approaching the first terminal 51 from the second lead portion 522, and is bent so that the second tip portion 523 is located above the first terminal 51. In this example, the second bent portion 524 is bent edgewise with respect to the vertical portion 522v of the second lead portion 522, and then bent flatwise.

[0027] <Case> As shown in FIG. 1, the case 6 houses the motor 4, multiple terminals 5, a push lifter 7, a locking member 8, and a transmission mechanism 9. One of the features of the lid locking structure 1 of the embodiment is that the case 6 has a portion for positioning the multiple terminals 5, as shown in FIG. 2. The portion for positioning the multiple terminals 5 includes a first support surface 66 and a second support surface 67, as shown in FIGS. 5 and 6. The case 6 is composed of, for example, a container-shaped main body having an opening, and a lid that covers the opening of the main body. The main body is large enough to house the motor 4 and other components. FIGS. 1, 2, 5, and 6 show the case 6 with the lid removed, exposing the internal structure of the case 6.

[0028] 2, the case 6 has a storage recess 60 for storing the motor 4, and a drawer portion 62 for storing the tip end portions of the terminals 5. The case 6 is a molded body made of, for example, resin.

[0029] A wall 61 is provided between the storage recess 60 and the drawer portion 62. The wall 61 is a wall that constitutes the storage recess 60 and also a wall that constitutes the drawer portion 62. A first recess 611 and a second recess 612 are provided on the upper surface of the wall 61. A horizontal portion 512h of the first lead portion 512 is placed in the first recess 611. The horizontal portion 512h is positioned in the left-right direction by the first recess 611. A horizontal portion 522h of the second lead portion 522 is placed in the second recess 612. The horizontal portion 522h is positioned in the left-right direction by the second recess 612. Because the walls 61 that constitute each of the first recess 611 and the second recess 612 are disposed between the first recess 611 and the second recess 612, the horizontal portion 512h and the horizontal portion 522h do not come into contact with each other. The left-right direction is the direction in which the first terminal 51 and the second terminal 52 are arranged side by side.

[0030] The lead-out portion 62 is composed of a wall portion 61 and side portions 62a and 62b. The side portions 62a and 62b are arranged facing each other at a distance so as to contain the first recessed portion 611 and the second recessed portion 612. The side portion 62a extends from the wall portion 61 in a direction away from the motor 4. The side portion 62b is arranged at a distance from the wall portion 61 so as to face the second recessed portion 612. A first wall portion 63 and a second wall portion 64 are arranged between the side portions 62a and 62b so as to face each other at a distance. The first wall portion 63 and the second wall portion 64 are provided to position the first terminal 51 and the second terminal 52.

[0031] As shown in FIGS. 5 and 6 , the first wall portion 63 includes a base-side horizontal wall portion 631, a vertical wall portion 632, and a tip-side horizontal wall portion 633. The base-side horizontal wall portion 631 and the tip-side horizontal wall portion 633 each extend from the side portion 62a toward the side portion 62b. The base-side horizontal wall portion 631 is spaced apart from the wall portion 61 so as to face the first recess 611. The tip-side horizontal wall portion 633 is spaced apart from the base-side horizontal wall portion 631 so as to face the base-side horizontal wall portion 631. The vertical wall portion 632 is provided to connect the end surface of the base-side horizontal wall portion 631 and the end surface of the tip-side horizontal wall portion 633.

[0032] As shown in FIGS. 5 and 6 , the second wall portion 64 includes a vertical wall portion 642 and a horizontal wall portion 643. The vertical wall portion 642 is arranged along the side portion 62b. The vertical wall portion 642 is arranged at a distance from the wall portion 61 so that an end face of the vertical wall portion 642 faces the second recessed portion 612. The vertical wall portion 642 is arranged at a distance from the vertical wall portion 632 so as to face the vertical wall portion 632. The horizontal wall portion 643 extends from the side portion 62b toward the tip-side horizontal wall portion 633. A gap is provided between the tip-side horizontal wall portion 633 and the horizontal wall portion 643, the gap being smaller than the gap between the vertical wall portion 632 and the vertical wall portion 642.

[0033] The vertical portion 512v and the first bent portion 514 (FIGS. 3 and 4) of the first lead portion 512 are disposed in the gap (FIGS. 5 and 6) between the wall portion 61 and the base-side horizontal wall portion 631. The lower surface of the case 6 in this gap serves as a first support surface 66 that supports the lower surface 514u of the first bent portion 514. A portion of the first tip portion 513 (FIGS. 3 and 4) is disposed in the gap between the vertical wall portion 632 and the vertical wall portion 642 and in the gap between the tip-side horizontal wall portion 633 and the horizontal wall portion 643 (FIGS. 5 and 6). The lower surface of the case 6 in each gap serves as a support surface that supports a portion of the first tip portion 513. This support surface is substantially flush with the first support surface 66. In this example, a protrusion 66p is provided on the bottom surface of the case 6 between the tip-side horizontal wall portion 633 and the horizontal wall portion 643. The protrusion 66p corresponds to a step portion 513s provided on the lower surface of the first tip portion 513. The first terminal 51 is positioned by being disposed in each gap. In this example, the tip side portion of the first tip portion 513 is not supported by the case 6.

[0034] The vertical portion 522v of the second lead portion 522 and the second bent portion 524 (FIGS. 3 and 4) are arranged in the gaps (FIGS. 5 and 6) between the wall portion 61 and the end face of the side portion 62b, and between the wall portion 61 and the end face of the vertical wall portion 642. The lower surface of the case 6 in this gap is a second support surface 67 that supports a lower surface 524u of the second bent portion 524. The second support surface 67 is located closer to the opening of the case 6 than the first support surface 66. The opening of the case 6 is located on the opposite side from the bottom surface of the case 6. A step surface 68 is formed on the inner surface of the case 6 by the first support surface 66 and the second support surface 67. The height of the step surface 68 is determined so that a predetermined gap is formed between the first tip portion 513 and the second tip portion 523 when the lower surface 514u of the first bent portion 514 is supported by the first support surface 66 and the lower surface 524u of the second bent portion 524 is supported by the second support surface 67. The height of the stepped surface 68 is the sum of the maximum width of the first tip portion 513 and the predetermined gap. In this example, the maximum width of the first tip portion 513 is the length of the long side of the cross section of the rectangular wire. The first support surface 66 and the second support surface 67 are arranged side by side. A portion of the second tip portion 523 (FIGS. 3 and 4) is arranged in the gap between the vertical wall portion 632 and the vertical wall portion 642 and in the gap between the tip-side horizontal wall portion 633 and the horizontal wall portion 643 (FIGS. 5 and 6). The second tip portion 523 is arranged above the first tip portion 513 with a gap therebetween. The lower surface 524u of the second bent portion 524 is supported by the second support surface 67, so that the second terminal 52 is cantilevered by the case 6. As a result, the second tip portion 523 is disposed in midair without being supported by the case 6. The second terminal 52 is positioned by being arranged in each gap.

[0035] <Action and effect> In the lid lock structure 1 of the embodiment, the second tip portion 523 is arranged vertically above the first tip portion 513, but the lower surface 524u of the second bent portion 524 is supported by the second support surface 67, so that the second tip portion 523 is positioned so as not to drop under its own weight. In other words, the second tip portion 523 is positioned in the vertical direction in the air. The vertical direction is a direction perpendicular to the reference plane. A step surface 68 having a predetermined height is formed between the first support surface 66 and the second support surface 67, so that a gap is provided between the first tip portion 513 and the second tip portion 523, and contact between the first terminal 51 and the second terminal 52 is suppressed.

[0036] The second bent portion 524 is sandwiched in the gap between the wall portion 61 and the end face of the vertical wall portion 642, thereby restricting movement of the second tip portion 523 in the front-rear direction. The second tip portion 523 is sandwiched in the gap between the tip-side horizontal wall portion 633 and the horizontal wall portion 643, thereby restricting movement of the second tip portion 523 in the left-right direction. In other words, in the lid lock structure 1 of the embodiment, in addition to positioning the second tip portion 523 in the up-down direction, the second tip portion 523 is also positioned in both the front-rear direction and the left-right direction. The front-rear direction is the extension direction of the second tip portion 523. The left-right direction is a direction perpendicular to both the up-down direction and the front-rear direction.

[0037] When assembling the first terminal 51 and the second terminal 52 to the case 6, the first terminal 51 is placed in the case 6 first, followed by the second terminal 52. Because the first support surface 66 and the second support surface 67 are arranged side by side, the second support surface 67 does not interfere with the assembling of the first terminal 51. When assembling the second terminal 52 to the case 6, a gap can be formed between the first tip portion 513 and the second tip portion 523 simply by the lower surface 524u of the second bent portion 524 being supported by the second support surface 67. As described above, the case 6 has a plurality of gaps in which the first terminal 51 and the second terminal 52 are placed. Therefore, the first terminal 51 and the second terminal 52 can be easily positioned simply by placing them in the respective gaps.

[0038] Lid locking structures mounted on vehicles are usually often mounted in narrow areas of the vehicle, which can make it difficult to connect the multiple terminals 5 connected to the motor 4 to the connector. In the lid locking structure 1 of the embodiment, the first tip portion 513 and the second tip portion 523 are arranged vertically, so that the lid locking structure 1 can be adapted to fit into narrow areas depending on the vehicle layout. For example, if the first tip portion 513 and the second tip portion 523 were arranged horizontally, the lid locking structure 1 can be adapted to fit into areas where the vehicle layout would be significantly restricted.

[0039] The present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. For example, the following modifications are possible.

[0040] (1) The bending direction of each of the first bending portion 514 and the second bending portion 524 can be appropriately selected so as to transition from the horizontally arranged first lead portion 512 and the second lead portion 522 to the vertically arranged first tip portion 513 and the second tip portion 523.

[0041] (2) The motor 4 and the terminals 5 may be separate components, or may be pre-assembled into one unit.

[0042] (3) The plurality of terminals 5 may include three or more terminals including the first terminal 51 and the second terminal 52. The plurality of terminals 5 are arranged so as not to contact each other.

[0043] (4) The lid lock structure 1 can be applied to various opening / closing lids that cover openings in vehicle body panels. The opening / closing lids include doors. The doors include back doors and side doors. [Explanation of symbols]
