Description

  The present invention relates to an opening / closing body responsive device that responds to opening / closing of an opening / closing body such as a lid or a door.

Conventionally, for example, for a fuel lid of a vehicle, an urging force for opening the lid is stored in response to its closing movement, and when the lid is opened, the stored urging force is released to release the lid. An urging mechanism for urging is provided (see, for example, Patent Document 1).
In addition, a switch having a contact that contacts and separates in response to the opening / closing movement of the fuel lid is provided, thereby detecting the opening / closing of the lid and, for example, useful for a display operation for displaying the opening / closing of the lid. It is like that.

JP 2007-290573 A

  In the case of the above-mentioned conventional one, in order to urge the lid in the opening direction in response to the opening and closing of the fuel lid, and to detect the opening and closing of the lid, two parts, an urging mechanism and a switch, are necessary. Installing them also had the disadvantage of requiring two separate spaces and two separate operations.

  The present invention has been made in view of the above circumstances. Therefore, the object of the present invention is to urge the opening / closing body in the opening direction in response to opening / closing of the opening / closing body such as a lid or a door, and to open / close the opening / closing body. It is an object of the present invention to provide an opening / closing body responding device that does not require two parts to detect but can be completed with one part, and can reduce installation space and simplify installation work.

  In order to achieve the above object, the opening / closing body responsive device of the present invention stores an urging force for opening the opening / closing body in response to the closing movement of the opening / closing body, and the stored urging force when the opening / closing body is opened. And an urging mechanism portion that urges the opening / closing body in the opening direction and is integrated with the urging mechanism portion, and the opening / closing movement of the opening / closing body is responsive to the opening / closing movement via the urging mechanism portion. And a switch portion having a contact.

  According to the above means, since the biasing mechanism part and the switch part are integrated, two parts are not required to obtain both functions, and one part can be used, and the installation space can be reduced. Reduction and simplification of installation work can be achieved.

Hereinafter, an example (one embodiment) of the present invention will be described with reference to the drawings.
First, FIG. 1 and FIG. 2 show the entire configuration of the apparatus in an assembled state, which is roughly composed of an urging mechanism portion 1 and a switch portion 2.
The urging mechanism portion 1 has a body 3 as a main body. As shown in FIG. 3, the body 3 has a collar portion 4 in the middle portion closer to the front (left side in the figure), and is forward of the collar portion 4. The front side portion 5 is cylindrical, and the rear rear side portion 6 is shaped like a prism.

  The rear side portion 6 further has a small prismatic portion 6a on the front side and a large prismatic portion 6b on the rear side. A mounting claw 7 is formed on the outer surface portion of the small prismatic portion 6a, and is connected to the large prismatic portion 6b. A hole 8 is formed. The attachment claw 7 is for attaching the body 3 to an attachment counterpart member (not shown), and the connection hole 8 is for connecting an insulator 25 described later to the body 3.

  As shown in FIGS. 1 and 2, the inside of the body 3 from the front side portion 5 to the front portion of the large prism portion 6b forms a circular sinus with the same diameter, and the inner peripheral surface portion includes a bulging wall. 9, the engaging portions 10 and 11 and the guide portions 12, 13, and 14 shown in FIG. Among these, the engaging portion 10 is a long groove extending in the axial direction (in the direction of arrow A in FIG. 4) from the rear edge of the bulging wall 9, and a plurality of the engaging portions 10 are arranged in the circumferential direction of the body 3 (in the direction of arrow B in FIG. 4). They are lined up at evenly spaced intervals. The engaging portion 11 is formed between the engaging portions 10 and is a recessed portion having a smaller depth from the rear edge of the bulging wall 9 to the front side than the engaging portion 10.

  The guide portions 12, 13, and 14 are rear edges of the bulging wall 9, the guide portion 12 extends obliquely from the open end of the engaging portion 10 to the back end of the engaging portion 11, and the guide portion 13 is the engaging portion. 11, the guide part 14 extends obliquely from the rear end of the guide part 13 to the open end of the adjacent engaging part 10.

  Inside the body 3, a shaft 15, a spring 16, and a rotor 17 are inserted in this order from the front. Of these, the shaft 15 has a short cylindrical shape with the front end closed as shown in FIG. 2 and the rear end opened, and as shown in FIG. 3, the shaft 15 protrudes at a plurality of locations (for example, three locations) on the outer peripheral surface. It has the part 18, and the protrusion 18 is inserted in each of the said engaging parts 10 as shown in FIG. Note that the number of engaging portions 10 is greater than or equal to the number of protrusions 18. Further, a plurality of teeth 19 are formed in a sawtooth shape with a substantially equal pitch on the peripheral edge of the rear end of the shaft 15. As shown in FIG. 2, the spring 16 is inserted into the shaft 15 and interposed between the front end portion of the shaft 15 and the rotor 17.

The rotor 17 has a short cylindrical shape, has a recess 20 that accommodates the rear end portion of the spring 16 on the front end surface portion, and has protrusions 21 at, for example, three locations on the outer peripheral surface portion as shown in FIG. Yes. The protrusion 21 extends in the axial direction, and its front end protrudes forward from the front end of the rotor 17 and forms a slope 21 a corresponding to the tooth 19 of the shaft 15. Further, as shown in FIG. 1, the front end portion of the projecting portion 21 enters each of the engaging portions 10 of the body 3. In addition, the rotor 17 has a flange portion 22 on the outer periphery of the rear end portion, and a recess portion 23 on the end surface portion.
A bag-like cover 24 made of rubber, for example, covering the front portion of the body 3 is attached to the front portion of the body 3 over the collar portion 4.

  The biasing mechanism portion 1 is composed as described above, while the switch portion 2 is mainly composed of the insulator 25. As shown in FIGS. 1 and 2, the insulator 25 has a rectangular parallelepiped box shape, and fixed contacts 26 and 27 are respectively provided on the opposing wall surfaces, and the fixed contact 26 is made longer than the fixed contact 27 forward. ing. The rear ends of the fixed contacts 26 and 27 are connection terminals 29 and 30 located in a connector case portion 28 that is formed to extend outside the insulator 25.

  Inside the insulator 25, a spring 31, a movable contact 32, and a retainer 33 to which the movable contact 32 is attached are accommodated in order from the rear, and the movable contact 32 is urged by the urging force of the spring 31 as urging means. Normally, it is in contact with the front portion of the fixed contact 26 and is held away from the fixed contact 27. The retainer 33 has a protrusion 32a on the rear side and a protrusion 32b on the front side, and the movable contact 32 is attached to the rear protrusion 32a.

A mounting claw 34 is formed on the outer surface portion of the insulator 25, and the insulator 25 is inserted while inserting the protrusion 32 b on the front side of the retainer 33 into the recess 23 at the rear end portion of the rotor 17 in the biasing mechanism portion 1. Is inserted into the rear portion (large prism portion 6b) of the body 3 and the attachment claws 34 are engaged with the connection holes 8, thereby connecting the insulator 25 to the body 3 and thus the switch portion 2. Are coupled to and integrated with the urging mechanism portion 1.
Therefore, in this case, the connecting hole 8 of the body 3 and the mounting claw 34 of the insulator 25 function as an integral means for integrating the biasing mechanism portion 1 and the switch portion 2.

Next, the operation of the above configuration will be described.
1, FIG. 2, and FIG. 5 (a) show the normal state of the entire apparatus. At this time, in the switch portion 2, the retainer 33 is pushed toward the biasing mechanism portion 1 by the biasing force of the spring 31, so that the movable contact 32 is in contact with the fixed contact 26 but is separated from the fixed contact 27. Therefore, it is in a so-called switch-off state.

  On the other hand, in the urging mechanism portion 1, the rotor 17 is pushed toward the front side of the body 3 by the retainer 33, so that the inclined surface 21 a of the front end portion of the projecting portion 21 forms the inclined surface of one tooth 19 of the shaft 15. In contact therewith, the shaft 15 is pressed. At this time, the front end of the protrusion 21 is also located in the engagement portion 10 of the body 3. Further, at this time, the shaft 15 pressed by the rotor 17 protrudes from the body 3 while pushing the cover 24 forward, but the protrusion 18 reaches the front end of the engaging portion 10 of the body 3 and stops. As a result, further protrusion of the shaft 15 is stopped.

  In front of the cover 24, an unillustrated opening / closing body, for example, a fuel lid of a vehicle is present in a so-called half-open state, and the fuel lid is in contact with the cover 24 on the back surface.

  From this state, when the fuel lid is pushed in to close, the shaft 15 is pushed backward together with the cover 24 by the fuel lid. As a result, the rotor 17 pushes the slope 21a of the projection 21 against the slope of one tooth 19 of the shaft 15 and resists the biasing force of the spring 31, and the arrow C and the two-dot chain line in FIG. Move backwards as shown. At this time, the shaft 15 does not rotate because the protrusion 18 is guided by the engaging portion 10 of the body 3 and moves backward.

  At this time, the rotor 17 is rotated by the component action of the inclined surface 21 by the pressing of the inclined surface 21 a of the protruding portion 21 from the inclined surface of one tooth 19 of the shaft 15. When escaped from the engaging portion 10, the slope 21 a moves to a position facing the adjacent guide portion 12 as indicated by an arrow D and a solid line in FIG.

  Next, when the pushing of the fuel lid is released, the pushed-in shaft 15 and the rotor 17 are also released, so that the urging force of the spring 31 moves in the returning direction. While the inclined surface 21a of the portion 21 is in contact with the inclined surface of the next one tooth 19 of the shaft 15, the rotor 17 itself rotates and passes over the next one tooth 19 while pushing the shaft 15 forward. At the same time, the inclined surface 21a of the protrusion 21 of the rotor 17 reaches a position where it slides on the above-mentioned guide portion 12 in contact with the engaging portion 11 as shown by an arrow E in FIG. Further recovery of the rotor 17 and the shaft 15 is prevented. Also at this time, the shaft 15 does not rotate as the protrusion 18 moves forward while being guided by the engaging portion 10 of the body 3.

  Thus, the entire apparatus is held in the push state shown in FIG. 6. In this state, the spring 31 is slightly extended from when the fuel lid is pushed in and closed, but at the initial normal state (FIG. 1). ) Is still in a sufficiently compressed state, that is, in a state where the urging force for opening the fuel lid is stored.

During this time (since the fuel lid is pushed in and closed), in the switch unit 2, the retainer 33 is pushed by the rotor 17 to move the movable contact 32 backward, so that the movable contact 32 is fixed to the fixed contact 26. And the fixed contact 27, that is, the movable contact 32 is bridged between the two fixed contacts 26 and 27, and is in a so-called switch-on state.
At this time, the fuel lid is locked in a closed state by a lock mechanism (not shown).

  Thereafter, when the lock of the fuel lid is released, the shaft 15 moves forward while pushing the cover 24 by the biasing force of the spring 16, and the fuel lid is slightly pushed open through the cover 24.

  Next, when the fuel lid is pushed in again, the shaft 15 together with the cover 24 is pushed rearward by the fuel lid as described above, so that the rotor 17 causes the slope 21a of the protrusion 21 to the slope of the next one tooth 19 of the shaft 15. Is pushed against the urging force of the spring 31 and moved rearward as indicated by an arrow F and a two-dot chain line in FIG. At this time, as described above, the rotor 17 is rotated by the component action of the inclined surface by the pressing of the inclined surface 21a of the protruding portion 21 from the inclined surface of the next one tooth 19 of the shaft 15, When the part 21 has escaped from the guide part 13 from the engaging part 11 of the body 3, as shown by an arrow G and a solid line in the figure, the inclined surface 21a further moves to a position facing the adjacent guide part 14. Also at this time, the shaft 15 does not rotate because the protrusion 18 is retracted while being guided by the engaging portion 10 of the body 3.

  Further, when the push-in of the fuel lid is released, the push-in of the pushed-in shaft 15 and the rotor 17 is also released, so that the biasing force of the spring 31, that is, the spring 31 stores the aforementioned biasing force. When released, it is moved in the return direction. Accordingly, the inclined surface 21a of the protrusion 21 of the rotor 17 is in contact with the inclined surface of the next one tooth 19 of the shaft 15 and pushes the shaft 15 forward, while the rotor 17 itself rotates, and further One tooth 19 is exceeded. At the same time, as shown by an arrow H in FIG. 5 (e), the protrusion 21 of the rotor 17 slides on the above-described guide portion 14 to enter the engagement portion 10, and further, the engagement portion 10 is moved forward to reach a position where it is hit by the rear end of the engaging portion 10, and further return of the rotor 17 and the shaft 15 is stopped. Also at this time, the shaft 15 does not rotate as the protrusion 18 moves forward while being guided by the engaging portion 10 of the body 3.

Thus, the entire apparatus returns to the initial state, and accordingly, the fuel lid returns to the aforementioned half-open state. Therefore, after that, the fuel lid can be fully opened by putting the hand on the fuel lid and pulling it. On the other hand, in this case, in the switch portion 2, the retainer 33 is pushed back toward the biasing mechanism portion 1 by the biasing force of the spring 31, whereby the movable contact 32 is separated from the fixed contact 27 and returns to a so-called switch-off state. .
Thereafter, the above-described operation is repeated every time the fuel lid is opened and closed.

  Thus, in the above configuration, the urging mechanism unit 1 stores the urging force for opening the lid in response to the closing movement of the fuel lid that is the opening / closing body, and the stored urging force when the lid is opened. The switch portion 2 urges the lid in the opening direction, and the switch portion 2 includes a movable contact 32 and fixed contacts 26 and 27 which are moved in response to the opening and closing movement of the fuel lid via the biasing mechanism portion 1. The biasing mechanism portion 1 and the switch portion 2 are combined and integrated. Accordingly, two parts are not required to obtain both of these functions, and only one part can be used, so that the installation space can be reduced and the installation work can be simplified.

The opening / closing body exemplified by the fuel lid may be another opening / closing body such as a trunk lid or a door of the vehicle, and may be an opening / closing body other than the vehicle.
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.

  In the drawings, 1 is an urging mechanism portion, 2 is a switch portion, 8 is a connecting hole (integrating means), 10 and 11 are engaging portions, 12 to 14 are guide portions, 15 is a shaft, 17 is a rotor, and 18 is Projections, 19 are teeth, 21 are projections, 26 and 27 are fixed contacts, 31 is a spring (biasing means), 32 is a movable contact, and 34 is an attachment claw (integration means).
