Description

[Technical Field]

[0001] The present invention is a mounting structure for a lid that is attached to the body of a vehicle such as an automobile to cover the body's fuel filler port, charging port, etc., and has an openable and closable lid, and is particularly useful for a lid that can move to a fully open position without stopping midway when the lock on the vehicle body is released. [Background technology]

[0002] When refueling or filling an automobile fuel tank with fuel such as gasoline or hydrogen, the fuel filler cap or filler lid (also called a lid) that covers the fuel filler or filler port on the vehicle body is opened, the fuel cap is removed, and fuel is added through the filler port, or a filler plug is inserted into the filler port to fill hydrogen. Furthermore, when charging an electric vehicle or PHV (plug-in hybrid vehicle), the charging lid is opened and a charging connector is inserted into a quick charge port or normal charge port to charge.

[0003] For example, when filling a fuel tank for an automobile, as shown in Figure 1, a lid (fuel filler lid) 110 that covers a fuel filler opening 101 provided on a vehicle body 201 is opened, and fuel is filled through the fuel filler opening 101. A lid mounting member 200 is attached to the back surface of the lid 110. The lid mounting member 200 has a large curved arm 220 that enables the lid 110 to be opened and closed, and is attached to a box (fuel filler box) 300.

[0004] 9 is a cross-sectional view of an example of the mounting structure for lid 110. Box 300 has an opening 340 corresponding to fuel filler opening 101, and is composed of box main body 310 that is mounted to the vehicle body, and arm storage section 370 that rotatably stores arm 220 of lid mounting member 200.

[0005] The arm 220 is rotatably attached to the arm storage section 370. The symbol O in Figure 9 is the center of rotation of the arm. A spring 400 that engages with the spring engagement section 360 of the arm storage section 370 is attached to the arm 220.

[0006] Although not shown, spring 400 is roughly V-shaped and has an arm side portion 410 attached to spring attachment portion 240 of arm 220, an arm storage section side portion 420 engaged with and held by spring engagement portion 360 of arm storage section 370 of box 300, and a spring main body portion 430 located between arm side portion 410 and arm storage section side portion 420. Also formed is a spring protrusion 440 connected to arm side portion 410 of spring 400 for popping up the lid 110 slightly above the surface of vehicle body 201 when the lock with the vehicle body 201 side is released.

[0007] When the lid 110 is closed (fully closed), the spring main body 430 bends so as to narrow the distance between the arm side 410 and the arm storage section side 420 of the spring 400, and the spring protrusion 440 abuts against the inner wall of the arm storage section 370 and bends toward the spring main body 430, with both being biased in the direction of returning to their original shapes. As a result, when the lock between the lid 110 and the vehicle body 201 side (box 300) is released during refueling or the like, the biasing forces of the spring protrusion 440 and the spring main body 430 cause the arm 220 to rotate in the direction of opening the lid 110 (for example, Patent Document 1).

[0008] Patent Document 1 describes that the rotation of arm 220 causes the tip of lid 110 to lift slightly from the surface of vehicle body 201, and that the lifted tip of lid 110 is then lifted by hand to fully open lid 110. However, when the biasing force of spring protrusion 440 is released, the position of arm side 410 of spring 400 becomes closer to box main body 310 than the line connecting spring engagement portion 360 and rotation center O of arm 220. Furthermore, if the biasing force of spring main body 430 is increased, when the lock between lid 110 and the vehicle body side is released, lid 110 can be moved to the fully open position without stopping midway, eliminating the need to fully open the lid manually.

[0009] [Patent Document 1] Japanese Patent Application Publication No. 2019-85086 Summary of the Invention [Problem to be solved by the invention]

[0010] Fig. 10 is an enlarged view of region Y in Fig. 9. In Fig. 10, the solid line indicates a state in which the lock between lid 110 and the vehicle body 201 (box 300) is released and the biasing force of spring protrusion 440 is released. Furthermore, the two-dot chain line indicates a state in which arm 220 has rotated from the solid line due to the biasing force of spring main body 430, and lid 110 is in the middle of opening. In Fig. 10, the arc-shaped dashed line indicates the center locus of arm side portion 410 of spring 400 when arm 220 rotates. Note that the spring protrusion 440 of spring 400 is not shown.

[0011] 10, in solid lines, the biasing force (arrow F) of spring main body 430 acts in the direction of the rotation center of arm 220. On the other hand, although arm 220 rotates in the direction of arrow f, the direction of arrow F and the direction of arrow f are significantly different, so the force that rotates arm 220 due to the biasing force of spring main body 430 does not become large, and the speed at which lid 110 begins to open is slow.

[0012] To increase the speed at which lid 110 begins to open, it is necessary to increase the force of arrow F to a certain extent. However, in that case, in spring 400, since spring main body 430 is in a bent state so as to narrow the distance between arm side portion 410 and arm storage section side portion 420 even while lid 110 is closed, arm storage section side portion 420 presses spring engagement portion 36 of arm storage section 370, and arm side portion 410 presses the engagement portion between arm 220 and arm storage section 370, it is necessary to increase the strength of arm 220 and arm storage section 370 at the portions that engage with spring 400.

[0013] On the other hand, when arm 220 is rotated from the solid line by the biasing force of spring main body 430 shown by the two-dot chain line, the direction of the biasing force of spring main body 430 (arrow F) and the rotation direction of arm 220 (arrow f) are substantially the same. Therefore, the opening speed of lid 110 increases. As a result, lid 110 starts to open slowly, and the opening speed gradually increases.

[0014] To provide a lid mounting structure that moves to a fully open position without stopping midway when the lock with a vehicle body is released, and that enables the speed at which the lid opens to be adjusted. [Means for solving the problem]

[0015] In order to solve the above problem, the present invention of claim 1 provides a lid mounting structure in which a lid that covers a fuel filler port or charging port, etc. on a vehicle body is attached with or integrated with a lid mounting member having a lid mounting portion for mounting the lid and an arm that extends and curves from the lid mounting portion, and the fuel filler port or charging port, etc. is attached with a box main body portion in which an opening for the fuel filler port, charging port, etc. is formed, and a box is attached with an arm storage portion that is connected to the box main body and stores the arm of the lid mounting member, and the arm storage portion side engaging portion formed in the arm storage portion engages with the arm side engaging portion formed on the arm to make the arm rotatable, and a spring attached to the spring mounting portion of the arm engages with the spring engaging portion formed in the arm storage portion, and the spring engaging portion is formed in multiple locations.

[0016] In the present invention of claim 1, the spring engagement portion is formed in multiple locations, so the position of the spring engagement portion can be changed within the same box. As a result, the relationship between the direction of the biasing force of the spring body of the spring and the rotation direction of the arm can be changed, making it possible to adjust the speed at which the lid opens. As a result, the feeling of how the lid opens can be improved.

[0017] Furthermore, since the spring engaging portions are formed in multiple locations, it is not necessary to manufacture multiple boxes each having an arm housing portion with a different position of the spring engaging portion, which results in cost reduction.

[0018] The present invention of claim 2 is a lid mounting structure in the invention of claim 1, in which the spring engagement portion is formed on an arc centered on the spring mounting portion formed on the arm when the lid is fully closed.

[0019] In the present invention of claim 2, the spring engagement portion is formed on an arc centered on the spring attachment portion formed on the arm when the lid is fully closed, so if the same spring is used, the same biasing force acts on the spring when the lid begins to open. As a result, the speed at which the lid opens can be adjusted using one spring, improving the feel of how the lid opens and eliminating the need to manufacture multiple springs, thereby reducing costs. [Effects of the Invention]

[0020] A lid for covering a vehicle's fuel filler or charging port, etc., is attached to or integrated with a lid mounting member having a lid mounting portion for mounting the lid and an arm extending in a curved manner from the lid mounting portion. The fuel filler or charging port, etc., is attached to the fuel filler or charging port, etc., with a box main body portion having an opening for the fuel filler or charging port, etc., and a box connected to the box main body portion and having an arm storage portion for storing the arm of the lid mounting member. An arm storage portion-side engaging portion formed in the arm storage portion engages with an arm-side engaging portion formed in the arm to enable rotation of the arm, and a spring attached to the arm engages with a spring engaging portion formed in the arm storage portion. The position of the spring engaging portion can be changed even in the same box, where the spring engaging portion is formed in multiple locations. As a result, the relationship between the direction of the biasing force of the spring main body of the spring and the rotation direction of the arm can be changed, thereby adjusting the speed at which the lid opens. This improves the feel of how the lid opens. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] An embodiment of the present invention will be described with reference to Figures 1 to 8. The following embodiment describes an attachment structure for a lid (fuel filler lid) that closes a fuel filler opening on a vehicle body and has an openable and closable lid, but it can also be used when filling hydrogen by inserting a filling plug into a filling port, or when charging electricity in an electric vehicle or a PHV (plug-in hybrid vehicle).

[0023] As shown in Figure 1, lid 11 is formed to fit the shape of fuel filler opening 1 in order to close the fuel filler opening 1 of vehicle body 2. When filling a fuel tank for an automobile, lid 11 that closes fuel filler opening 1 provided on vehicle body 2 is opened, and fuel is filled through fuel filler opening 1. A lid mounting member 20 is attached to the back surface of lid 11, and lid mounting member 20 is attached to box 30.

[0024] 2, the lid mounting member 20 has a lid mounting portion 21 that is attached to the lid 11, and a greatly curved, arc-shaped arm 22 that enables the lid 11 to be opened and closed. The lid mounting portion 21 also has a lid lock portion 23 that engages with a lock pin 32 of the box 30, which will be described later. The lid 11 and the lid mounting member 20 may also be formed integrally.

[0025] The box 30 attached to the vehicle body 2 has a box main body 31 with an opening 34 at the fuel filler opening 1, and an arm storage section 37 for storing the arm 22 of the lid mounting member 20. To ensure sufficient space for the arm 22 to be opened and closed within the box 30, the arm storage section 37 is formed further inward into the vehicle body 2 than the box holder 3 that holds the box main body 31 to the vehicle body 2. Therefore, the rotation center O of the arm 22 is located further inside the arm storage section 37 than the lid 11 in the lateral direction. Although not shown, an arm-side engaging portion including the rotation center O formed on the arm 22 engages with an arm-side engaging portion formed on the arm storage section 37, allowing the arm 22 to rotate. Both the box 30 and the lid mounting member 20, including the arm 22, are made of resin. The arm storage section 37 will be described in detail later.

[0026] A sealing member 33 is attached around the upper end of the box main body 31, and when the box main body 31 is attached to the box holding portion 3 of the vehicle body 2, it seals the gap between the box holding portion 3 of the vehicle body 2 and the upper end of the box main body 31.

[0027] A lock pin 32 is formed on the box body 31 on the side opposite the arm storage section 37 of the box 30, and when the lid 11 is closed, the lock pin 32 engages with the lid lock section 23 of the lid mounting member 20 to lock the lid 11. When the lid 11 is opened, the lock pin 32 of the box 30 retracts and disengages from the lid lock section 23 of the lid mounting section 21.

[0028] Figure 3 is an enlarged cross-sectional view of region C in Figure 2. Note that spring 40 is not shown. Figure 4 is a cross-sectional view taken along line BB in Figure 3. In Figure 3, O is the rotation center of arm 22. In Figure 3, the solid line indicates when lid 11 is fully closed, the two-dot chain line indicates when lid 11 is fully open, and the one-dot chain line indicates a position when lid 11 is opened approximately 90 degrees from the fully closed position (solid line).

[0029] Furthermore, a spring mounting portion 24, which is a through hole, is formed in the arm 22, and an arm side portion 41 of a spring 40 (described later) is inserted into and mounted in the spring mounting portion 24. O' indicates the center of the spring mounting portion 24. Furthermore, the position of O' moves along the dashed line as the arm 22 rotates.

[0030] Furthermore, when the lid 11 is fully closed, O' is located closer to the box main body 31 than the line connecting the arm storage section side 42 of the spring 40 (described later) and O. As a result, the lid 11 begins to open at the same time that the lock pin 32 of the box 30 retreats and disengages from the lid lock section 23 of the lid mounting section 21, eliminating the need to form the spring protrusion 440 in the background art.

[0031] At the rear longitudinal side of the arm storage section 37 of the box 30, there is formed a spring engagement section forming section 38, the space of which expands from the vehicle body 2 side toward the inside of the vehicle, and a bottom surface section 39, which connects the spring engagement section forming section 38 and the box main body section 31.

[0032] The spring engagement portion forming portion 38 is formed in an arc shape centered at the center O' of the spring mounting portion 24 of the arm 22 when the lid 11 is fully closed, i.e., the solid line position O'. On the inner surface of the spring engagement portion forming portion 38, three spring engagement portions 36, i.e., a first spring engagement portion 50, a second spring engagement portion 51, and a third spring engagement portion 52, are formed so as to protrude from the inner surface in the direction toward the vehicle body 2.

[0033] The first spring engagement portion 50, the second spring engagement portion 51, and the third spring engagement portion 52 are prisms with a substantially triangular cross section and are of the same shape. The number of spring engagement portions 36 is not limited to three. The cross-sectional shape does not have to be triangular or the same shape as long as the arm storage portion side portion 42 of the spring 40, which will be described later, engages with the spring engagement portion 36 when the lid 11 is opened or closed. Furthermore, the first spring engagement portion 50, the second spring engagement portion 51, and the third spring engagement portion 52 may be formed as recesses on the inner surface of the spring engagement portion forming portion 38.

[0034] 3, the first spring engagement portion 50 and the third spring engagement portion 52 are spaced apart by approximately 50 degrees from O'. The second spring engagement portion 51 is formed midway between the first spring engagement portion 50 and the third spring engagement portion 52. Note that the angles of the first spring engagement portion 50 and the third spring engagement portion 52 from O' and the formation position of the second spring engagement portion 51 are not limited to those described above.

[0035] The spring engagement portion forming portion 38 is formed in an arc shape centered on the center O' of the spring mounting portion 24 of the arm 22 when the lid 11 is fully closed, and the first spring engagement portion 50, second spring engagement portion 51 and third spring engagement portion 52 are formed inside it on an arc centered on the center O' of the spring mounting portion 24.As a result, when the lock pin 32 of the box 30 retracts and disengages from the lid lock portion 23 of the lid mounting portion 21 and the lid 11 begins to open, if the same spring 40 is used, the same spring force acts on the spring main body portion 43 of the spring 40 described below.

[0036] FIG. 5 is a plan view of a spring 40 used in an embodiment of the present invention. The spring 40 is manufactured by bending a single metal wire into a U-shape. The spring 40 has an arm storage section side section 42 that is held by the spring engagement section 36 of the arm storage section 37, an arm side section 41 that is attached to the spring attachment section 24 of the arm 22, and a spring main section 43 that connects the arm storage section side section 42 and the arm side section 41. The arm storage section side section 42, the arm side section 41, and the spring main section 43 are formed as a single plane. Here, the plane formed by the arm storage section side section 42 and the arm side section 41 is called a spring plane 44.

[0037] 6A and 6B are cross-sectional views of the arm storage section side portion 42 of the spring 40 engaged with the first spring engagement portion 50 of the spring engagement portion forming portion 38, with Fig. 6A showing the lid 11 when fully closed, i.e., the position immediately before the lid 11 opens, and Fig. 6B showing the lid 11 in the middle of opening. The position of the first spring engagement portion 50 is formed slightly closer to the vehicle body 2 than the position of the spring engagement portion 360 in Fig. 10. In Fig. 6, the dashed line indicates the locus of O'.

[0038] As shown in Figure 6(a), the direction of the biasing force of spring main body 43 (arrow F) acts toward the center of rotation of arm 22. Since there is a large deviation in the direction of the force from the rotation direction of arm 22 (arrow f), the speed at which lid 11 starts to open is quite slow.

[0039] To increase the speed at which lid 11 starts to open, it is necessary to increase the biasing force of spring main body 43 to a certain extent, for example by making spring 40 thicker. However, even when lid 11 is fully closed as shown in Figure 6(a), arm storage section side portion 42 of spring 40 presses first spring engagement portion 50 of spring engagement section forming portion 38 of arm storage section 37, and arm side portion 41 of spring 40 presses the engagement portion between arm 22 and arm storage section 37. Therefore, it should be noted that if spring 40 is made thicker, the load on arm 22 and spring engagement section forming portion 38 of arm storage section 37 at the portion engaging with spring 40 will increase.

[0040] On the other hand, in FIG. 6(b), the angle formed by the direction of the biasing force (arrow F) of the spring main body 43 and the rotation direction (arrow f) of the arm 22 is smaller, and the positional relationship is reversed. That is, in FIG. 6(a), the biasing force (arrow F) of the spring main body 43 is above the rotation direction (arrow f) of the arm 22, but in FIG. 6(b), the biasing force (arrow F) of the spring main body 43 is below the rotation direction (arrow f) of the arm 22. Therefore, between FIG. 6(a) and FIG. 6(b), the direction of the biasing force (arrow F) of the spring main body 43 and the rotation direction (arrow f) of the arm 22 coincide. As a result, when the arm storage section side section 42 of the spring 40 is engaged with the first spring engagement section 50 of the spring engagement section forming section 38, the opening speed of the lid 11 is small at the beginning, gradually increases, and then slightly decelerates until it reaches the fully open state.

[0041] Next, a case where the arm storage section side portion 42 of the spring 40 is engaged with the second spring engagement portion 51 of the spring engagement portion forming portion 38 will be described with reference to FIG. 7. The spring 40 used is the same as that used in the first spring engagement portion 50 described above. As in the case of FIG. 6, FIG. 7(a) shows the lid 11 when it is fully closed, that is, in the position immediately before the lid 11 opens, and FIG. 7(b) is a cross-sectional view illustrating the lid 11 in the middle of opening. The second spring engagement portion 51 is formed in a position shifted approximately 25 degrees toward the vehicle body 2 from the first spring engagement portion 50 described above.

[0042] As shown in Figure 7(a), in the case of the second spring engagement part 51, the direction of the biasing force of the spring main body part 43 (arrow F) is above the rotation direction (arrow f) of the arm 22, as in Figure 6(a), but the angle formed by F and f is much smaller than in Figure 6(a). Therefore, the speed at which the lid 11 starts to open is faster than in the case of the first spring engagement part 50.

[0043] 7(b), the positional relationship between the direction of the biasing force of the spring main body 43 (arrow F) and the rotation direction of the arm 22 (arrow f) is reversed, as in the case of the first spring engagement part 50. Also, the angular deviation between the direction of the biasing force of the spring main body 43 (arrow F) and the rotation direction of the arm 22 (arrow f) is greater than in the case of the first spring engagement part 50. Therefore, when the arm storage part side part 42 of the spring 40 is engaged with the second spring engagement part 51 of the spring engagement part forming part 38, the lid 11 begins to open at a greater speed than in the case of the first spring engagement part 50, the speed temporarily increases, and then the lid 11 reaches the fully open state with a greater degree of deceleration than in the case of the first spring engagement part 50.

[0044] Next, a case where the arm storage section side portion 42 of the spring 40 is engaged with the third spring engagement portion 52 of the spring engagement portion forming portion 38 will be described with reference to Fig. 8. The spring 40 used is the same as that used in the first spring engagement portion 50 described above. As in Fig. 6, Fig. 8(a) shows the lid 11 when fully closed, that is, in the position immediately before the lid 11 opens, and Fig. 8(b) is a cross-sectional view illustrating the lid 11 in the middle of opening. The third spring engagement portion 52 is formed in a position shifted approximately 25 degrees toward the vehicle body 2 from the second spring engagement portion 51 described above.

[0045] 8(a), in the case of the third spring engagement portion 52, the direction of the biasing force (arrow F) of the spring main body 43 is substantially the same as the rotation direction (arrow f) of the arm 22. Therefore, the speed at which the lid 11 starts to open is the greatest.

[0046] On the other hand, in Figure 8(b), the angle between the direction of the biasing force of the spring main body 43 (arrow F) and the rotation direction of the arm 22 (arrow f) is increasing. Therefore, the angle between the direction of the biasing force of the spring main body 43 (arrow F) and the rotation direction of the arm 22 (arrow f) is gradually increasing from Figure 8(a) to Figure 8(b). As a result, when the arm storage section side section 42 of the spring 40 is engaged with the third spring engagement section 52 of the spring engagement section forming section 38, the lid 11 starts to open forcefully and gradually decelerates until it reaches the fully open state.

[0047] 6 to 8, three spring engagement portions 36 (first spring engagement portion 50, second spring engagement portion 51, and third spring engagement portion 52) are formed in spring engagement portion forming portion 38, and arm storage portion side portion 42 of spring 40 is engaged at each position, thereby changing the relationship between the direction of the biasing force of spring main body portion 430 (arrow F) and the rotation direction of arm 220 (arrow f). As a result, the speed at which lid 11 opens can be adjusted, improving the feel of how lid 11 opens.

[0048] In addition, since the spring engaging portions 36 are formed in multiple locations, there is no need to manufacture multiple boxes 30 each having an arm housing portion 37 with different positions of the spring engaging portions 36. As a result, costs can be reduced.

[0049] Furthermore, since the spring engagement portion 36 is formed in multiple locations, by changing the position of the spring engagement portion 36 that engages with the spring 40, it is possible to realize, for example, a way of opening the lid 11 that suits the user's preferences.

[0050] Furthermore, because the first spring engagement portion 50, the second spring engagement portion 51, and the third spring engagement portion 52 are formed on an arc centered on the center O' of the spring mounting portion 24, when the lid 11 begins to open, the same biasing force acts on the spring 40, although in different directions. As a result, the speed at which the lid 11 opens can be adjusted using one spring 40, improving the feel of how the lid 11 opens and eliminating the need to manufacture multiple springs, thereby reducing costs.

[0051] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the object of the present invention.

[0052] For example, in the above embodiment, the spring engagement portion 36 is formed on an arc centered on the center O' of the spring mounting portion 24 of the arm 22 when the lid 11 is fully closed, that is, the center O' of the spring mounting portion 24 when the arm 22 is in the solid line position in Figure 3, and when the lid 11 begins to open, if the same spring 40 is used, the same spring force acts on the spring main body portion 43 of the spring 40.However, the spring engagement portion 36 (first spring engagement portion 50, second spring engagement portion 51, third spring engagement portion 52) may be formed at positions where the spring force of the spring main body portion 43 of the spring 40 at the first spring engagement portion 50, second spring engagement portion 51, and third spring engagement portion 52 is different when the lid 11 is fully closed.
