Description

The present invention relates to a lid mounting portion structure of a vehicle to which a fuel lid, a charging lid, or the like is mounted in a vehicle such as an automobile.

The applicant has previously proposed the structure described in Patent Document 1 as an example of the structure of the lid mounting portion of the vehicle.
In the structure described in the document, the panel opening for the fuel filler port provided on the vehicle body panel can be opened and closed by a lid (fuel lid). An arm is continuously provided on the lid, and one end of the arm is supported by a rotation fulcrum, and the arm and the lid can open and close the panel opening by rotating around the rotation fulcrum. On the other hand, the arm is given an urging force in the direction in which the lid is opened by an urging member such as a spring. According to such a configuration, when the lid is closed and locked, when the locked state is released, the lid can be opened by using the urging force.

However, in the above-mentioned prior art, there is still room for improvement as described below.

That is, when the lid is closed, the urging force by the urging member always acts on the arm, causing continuous stress in the arm. Further, the urging force acts in the direction of rotating the lid, and causes bending stress in the arm. Therefore, the arm may be deformed by the creep phenomenon, and the lid may be displaced from the original appropriate position accordingly. If such a misalignment occurs, a step may be created between the lid and the vehicle body panel, or the width of the gap between the lid and the vehicle body panel formed around the lid may become uneven in various places. Problems such as poor appearance of the vehicle will occur.
The above-mentioned deformation of the arm becomes remarkable when the arm is made of resin in order to reduce the weight of the arm and the cost of parts, and the necessity of solving the above-mentioned problem becomes even greater.

Japanese Unexamined Patent Publication No. 2014-88110

The present invention has been conceived under the above-mentioned circumstances, and appropriately prevents or suppresses the arm connected to the lid from being deformed by the creep phenomenon and the lid from being improperly displaced. It is an object of the present invention to provide a lid mounting structure of a vehicle capable of capable.

In order to solve the above problems, the following technical measures are taken in the present invention.

The vehicle lid mounting structure provided by the present invention is connected to the lid for closing the opening provided in the vehicle and the lid so that the lid rotates to open and close the opening. It is a lid mounting part structure of a vehicle provided with a rotation fulcrum that rotatably supports the arm and a means for applying an urging force to a part of the arm in a direction in which the lid opens. In the closed state of the lid, the rotation fulcrum is located on or near the line of action of the urging force of the urging force applying means, and the arm has a flat first cam surface. And a second cam surface connected to the first cam surface at an angle intersecting with the first cam surface, and the urging force applying means is used to bring the first and second cam surfaces into contact with each other. A non-tilted plane as a plane along a direction substantially orthogonal to the line of action, and a chamfered inclined surface connected to one side of the non-tilted plane, are provided at the tip of the contact member. Is provided, and when the lid is closed, the first cam surface faces as a plane that is substantially orthogonal to the action line and parallel to the non-inclined plane of the contact member. On the other hand, when the lid is operated in the direction from the closed state to the open state, the second cam surface is in contact with the chamfered inclined surface of the contact member, and the lid is in the opening direction. It is characterized by being configured to receive urging forces.

According to such a configuration, the following effects can be obtained.
That is, in the closed state of the lid, the urging force by the urging force applying means can act on the arm in a state in which no bending stress is generated or hardly generated. As a result, unlike the prior art, the arm can be prevented or suppressed from being deformed by the creep phenomenon. Although the urging force acts as a mere compressive force on a part of the arm, such a force does not cause a large deformation of the arm. Therefore, according to the present invention, it is possible to eliminate the displacement of the lid from the original appropriate position due to the deformation of the arm, and to prevent a problem that the appearance of the lid mounting portion is deteriorated. be able to. When the arm is made of resin, it is particularly effective because it is easily deformed due to the urging force.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

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

The vehicle lid mounting structure A shown in FIG. 1 has a structure provided with a lid 3 (fuel lid) for the fuel filler port 10 of the fuel tank 1 of the vehicle, and a panel opening 50 provided in the vehicle body panel 5, this panel. It further includes an inlet box 2 (fuel inlet box) fitted in the opening 50, an arm 6 connected to the lid 3, an urging force applying unit 7, and a lock unit 4 for the lid.

The vehicle body panel 5 is, for example, a side outer panel, and the panel opening 50 corresponds to an example of the “opening provided in the vehicle” in the present invention. The flange portion 51 on the peripheral edge of the panel opening 50 is provided so as to be recessed from the outer surface of the general surface portion of the vehicle body panel 5, and when the lid 3 is closed, the lid 3 enters the recessed portion. Therefore, consideration is given so that the outer surfaces of the lid 3 and the vehicle body panel 5 are substantially flush with each other.

The inlet box 2 forms a main opening 20 that opens outward in the vehicle width direction, a frame-shaped flange 21 corresponding to the edge of the main opening 20, and a panel opening from the flange 21. It is provided with a side wall portion 22 protruding toward the inner portion side (inward side in the vehicle width direction) of the portion 50, and a back wall portion 23 connected to the innermost portion of the side wall portion 22. The back wall portion 23 is provided with an inlet opening 23a through which the fuel filler port pipe body portion 11 of the fuel tank 1 is inserted, and the fuel filler port 10 is located in the inlet box 2.

The lid 3 is for closing the panel opening 50 and the main opening 20, and is configured by joining the lid inner 3b to the inside of the lid outer 3a formed in a shape and size corresponding to the panel opening 50. ing. An arm 6 is continuously provided to the lid 3, and one end of the arm 6 is supported by a rotation fulcrum 60 formed of a shaft body or the like. The arm 6 and the lid 3 can rotate about the rotation fulcrum 60 in a substantially horizontal direction, and the panel opening 50 and the main opening 20 are opened and closed by the lid 3 by this rotation operation. A relatively large concave portion 69 is formed in a portion near one end of the arm 6 in order to avoid interfering with the front edge portion 29 of the inlet box 2 when the lid 3 is opened wide. Is.

The lock unit 4 for the lid is for performing a lock / unlock switching operation when the lid 3 is in the closed state, and is attached to the side wall portion 22 of the inlet box 2 near the rear of the vehicle. The lock unit 4 is, for example, an electromagnetic type, and supports a rod portion 40 having a locking engaging portion 43 at the tip thereof that can be engaged with and disengaged from the engaged portion 38 provided on the inner surface side of the lid 3. A housing case 46 is provided. An electromagnetic mechanism (not shown) capable of switching between fixing and releasing the rod portion 40 is housed in the housing case 46.

The locking engaging portion 43 is, for example, a small piece-shaped portion having a substantially elliptical circle or a substantially oblong rectangle. The rod portion 40 can reciprocate in the axial length direction with a rotational movement. As is well shown in FIG. 4A, when the lid 3 is fully closed, the locking engaging portion 43 makes the engaged opening 39 provided on the inner surface side of the lid 3 outward in the vehicle width direction. And engages with the engaged portion 38 of the lid 3 in a retaining state. When the lid 3 is locked, the above-mentioned state is maintained. On the other hand, at the time of unlocking, as shown in FIG. 3B, it is possible to release the engaged state between the locking engaging portion 43 and the engaged portion 38 to open the lid 3. Is. In the state shown in FIG. 3B, the width L1 of the locking engaging portion 43 in the plan view is changed to the width L2 in the plan view due to the rotation of the locking engaging portion 43. Is smaller than When the lid 3 is closed from the state shown in FIG. 3B, the locking engaging portion 43 is pushed by the pressing portion 37 of the lid 3 to rotate, and the state shown in FIG. It is possible.
When mounting the lock unit 4, as shown in FIG. 4A, a seal member 8 is interposed between the convex portion 59 provided on the lock unit 4 and the flange portion 21 of the inlet box 2. The flange portion 51 of the vehicle body panel 5 is sandwiched therein. According to such a configuration, advantages such as improving the sealing property between the flange portions 21 and 51 can be obtained.

In FIG. 1, the urging force applying unit 7 is for applying the urging force F to a portion of the arm 6 on the front end side in the opening direction of the lid 3, and is an example of the “urging force applying means” in the present invention. Corresponds to. The urging force applying unit 7 is housed in and abutted in a shaft-shaped abutting member 71 supported by the housing case 70 and reciprocally supported in a direction facing the arm 6, and in the housing case 70. An elastic member 72 such as a spring that exerts an elastic force on the abutting member 71 so that the tip end portion of the member 71 is pressed against the arm 6 is provided.

The rotation fulcrum 60 of the urging force applying unit 7 and the arm 6 is set so that the rotation fulcrum 60 is located on the action line La of the urging force F of the urging force applying unit 7. As is well shown in FIG. 2, the arm 6 has first and second cam surfaces 61 and 62 as surfaces with which the tip end portion of the contact member 71 abuts.
The first cam surface 61 is a surface that is brought into contact with the contact member 71 when the lid 3 is fully closed, and is preferably a surface that is substantially orthogonal to the action line La of the urging force F described above. .. The second cam surface 62 rotates clockwise from the state shown in FIG. 2 to the state shown in FIG. 3, and the contact state between the first cam surface 61 and the contact member 71 is eliminated. In the above, it is a surface to which the abutting member 71 abuts, and is, for example, a curved surface having an appropriate radius of curvature R.
A chamfered inclined surface 71a is provided at the tip of the contact member 71. According to such a configuration, the tip of the contact member 71 is brought into surface contact with the second cam surface 62. Can be done.

As is well shown in FIG. 2B, the inlet box 2 is provided with a pair of convex ribs 28 for backing up the portion near the tip of the contact member 71. Since the tip of the contact member 71 has a free end and receives a reaction force from the arm 6, the contact member 71 may be tilted or deformed in the direction indicated by the reference numeral Da in FIGS. 2 (b) and 3. .. In particular, when the lid 3 is operated from the open state to the closed state and the arm 6 rotates counterclockwise, the reaction force is considerably large, and the amount of inclination or deformation of the contact member 71 is also large. There is a risk of becoming. On the other hand, the pair of convex ribs 28 back up the contact member 71 and play a role of preventing or suppressing the inclination or deformation as described above. In the drawing, each convex rib 28 and the contact member 71 are shown in a state of being separated from each other through a minute gap, but these are brought into contact with each other so that each convex rib 28 is brought into contact with the contact member 71. It may be used as a slide guide for.

Although not shown in the illustration, the urging force applying unit 7 may inadvertently open the slide door provided on the side of the vehicle and collide with the lid 3 when the lid 3 is open. It is also used as a controller to prevent it. This function as a controller is obtained, for example, by connecting the urging force applying unit 7 and the operating mechanism of the stopper for the sliding door with a cable. More specifically, based on the fact that the position of the contact member 71 differs between when the lid 3 is in the open state and when it is in the closed state, the lid 3 is set to the open state and the contact member 71 is set. When is in a predetermined position, the cable is pulled accordingly. Then, the stopper for the sliding door operates so that the sliding door does not open more than a predetermined value. However, in the present invention, such a function may not be provided.

Next, the operation of the lid mounting portion structure A of the vehicle described above will be described.

First, the rotation fulcrum 60 of the arm 6 is located on the action line La of the urging force F of the urging force applying unit 7, and when the lid 3 is in the closed state (fully closed state), FIGS. As shown in a), the contact member 71 of the urging force applying unit 7 is in contact with the first cam surface 61 substantially orthogonal to the action line La. Therefore, when the lid 3 is in the closed state, the urging force F does not act as a rotational moment with respect to the arm 6, but merely acts as a force that partially presses the first cam surface 61. .. Therefore, a large bending stress is not generated in each part of the lid 3, and the deformation of the lid 3 due to the creep phenomenon is eliminated.

The arm 6 is preferably made of resin for the purpose of weight reduction and component cost reduction, but even when such a material is used, deformation due to the creep phenomenon does not occur due to the above-mentioned action. Can be. As a result, it is also possible to eliminate the occurrence of misalignment of the lid 3 due to the deformation of the arm 6. As a result, it is possible to prevent a problem such as a large step from being generated between the outer surface of the lid 3 and the outer surface of the vehicle body panel 5.

On the other hand, according to the above-described configuration, since it is not possible to generate a rotational force in the arm 6 when the lid 3 is closed, the lid 3 cannot be opened simply by releasing the locked state of the lid 3. On the other hand, for example, when a person opens the lid 3 slightly by hand, the contact member 71 of the urging force applying unit 7 comes into contact with the second cam surface 62, as shown in FIG. The second cam surface 62 is a curved surface having an appropriate inclination with respect to the action line La. Therefore, a rotational force is generated in the arm 6, and the lid 3 is automatically opened by using the urging force F. After that, the contact member 71 passes through the second cam surface 62, and the arm 6 can be further rotated.

As described above, in the present embodiment, when the lid 3 is closed, the arm 6 cannot be rotated by using the urging force F, but if the lid 3 is opened a little, the urging force F is used. Since the arm 6 can be positively rotated, there is no particular problem in practical use. The lock unit 4 can also be used as a means for opening the lid 3 slightly from the closed state. That is, when the locked state of the lid 3 by the lock unit 4 is released, the rod portion 40 may move forward and push the lid 3 outward in the vehicle width direction. The present invention can also adopt such means.

As described with reference to FIG. 2B and the like, the tip portion of the contact member 71 receives a reaction force from the arm 6 and tilts or deforms in the direction of the symbol Da, that is, a pair of convex ribs. Since it is prevented or suppressed by 28, the opening / closing operation of the lid 3 can be stabilized. Further, since it is not necessary to increase the supporting strength of the contact member 71 of the urging force applying unit 7 itself so much, it is possible to simplify the urging force applying unit 7 and reduce the cost.

The present invention is not limited to the contents of the above-described embodiments. The specific configuration of each part of the lid mounting part structure of the vehicle according to the present invention can be variously redesigned within the scope intended by the present invention.

In the present invention, the rotation fulcrum 60 of the arm 6 is preferably located on the action line La of the urging force F of the urging force applying unit 7, but is not limited to this, and is located in the vicinity of the action line La. It may be.

In the above-described embodiment, the structure of the mounting portion of the fuel lid has been described as an example, but the present invention is not limited thereto. For example, it is possible to use a lid mounting structure for charging a plug-in type electric vehicle or a hybrid vehicle. Further, the lid mounting portion structure for closing the opening for storing articles provided in the vehicle may be used, and the specific mounting location, shape, size, material, etc. of the lid are not limited. The arm connected to the lid is not limited to resin, and may be made of metal, for example. Even if the arm is made of metal, if it is thinned, deformation due to the creep phenomenon may occur, and this can be eliminated by the present invention.
The urging force applying means may be any means that can apply urging force to a part of the arm. The type of the elastic member for generating the urging force is not limited, and the specific shape of the abutting member for abutting the arm is not limited.
