  The present invention relates to a cover opening / closing structure.

  An example of a conventional cover opening / closing structure will be described with reference to FIGS. 9 is a perspective view showing a cover closed state in an example of a conventional cover opening / closing structure, FIG. 10 is a perspective view showing a cover open state in the cover opening / closing structure, and FIG. 11 shows a cover closed state in the cover opening / closing structure. FIG. 12 is a side view showing a cover open state in the cover opening and closing structure, FIG. 13A is an enlarged view of a portion A in FIG. 11, FIG. 13B is an enlarged view of a portion B in FIG. FIG. 5 is a front view showing an example of a cover closed state in the cover opening / closing structure.

  A cover 12 shown in the figure covers a USB connector or the like of a printed circuit board disposed behind the operation panel, and is opened when an external device is connected to the USB connector or the like. The cover holder 11 that guides the cover 12 is fastened to the chassis that supports the printed circuit board, but a screw insertion hole for fastening the cover holder 11 is not shown. An operation panel is arranged around the cover holder 11, but the operation panel is not shown.

  As shown in FIG. 10, a rectangular window 11m and a circular window 11n are formed on the front plate of the cover holder 11 to expose the USB connector and the like when the cover 12 is opened. On both sides of the cover holder 11, an upper side plate 11a and a lower side plate 11b are erected on the same plane, and the cover 12 is disposed between the side plates so as to be freely opened and closed.

  The upper side plates 11a, 11a of the cover holder 11 are formed with arc-shaped sliding contact surfaces 11c, 11c, and extend from the lower side plate 11b and the upper side plate 11a so as to cover both ends of the sliding contact surface 11c, respectively. An open side hinge 11d and a closed side hinge 11f are formed. An open-side convex portion 11g and a closed-side convex portion 11j are formed at the tip portions of the open-side hinge 11d and the closed-side hinge 11f, respectively.

  Side plates 12a, 12a adjacent to the upper side plates 11a, 11a of the cover holder 11 are formed on both sides of the cover 12, and the lower slidable contact surface 12b and the upper slidable contact are formed on an arcuate member extending vertically from the side plate 12a. A surface 12c is formed. When the cover 12 is opened and closed, the lower sliding contact surface 12b is in sliding contact with the sliding contact surface 11c of the cover holder 11, and the upper sliding contact surface 12c is in contact with the opening convex portion 11g or the closing convex portion 11j of the cover holder 11. Make sliding contact.

  As shown in FIGS. 9 and 11, when the cover 12 is open, the cover 12 is slid to the upper end position with a finger, and the closed convex portion 11j of the cover holder 11 is the cover closed concave portion of the cover 12. 10d and 12d, when the cover 12 is in the open state, the cover 12 is slid to the lower end position with a finger, and the open-side convex portion 11g of the cover holder 11 is The cover 12 enters the cover opening side recess 12e.

  Thus, when the cover 12 is in a closed state or an open state, the respective convex portions of the closed side hinge 11f and the open side hinge 11d are in an elastically deformed state that first comes into sliding contact with the upper sliding surface 12c, Next, since it changes from the natural state, it can be easily recognized that the sliding resistance has changed and the cover 12 has moved to the sliding end position.

  FIG. 11 shows a state in which the cover 12 is in the closed state, and FIG. 13A shows a portion A in FIG. FIG. 12 shows a state in which the cover 12 is in an open state, and FIG. 13B shows a portion B in FIG.

  In the above conventional cover opening / closing structure, the cover overstroke is taken into account so that the cover is securely locked, and the cover opening side recess 12e and the opening side protrusion 11g are formed between the cover closing recess 12d and the closing protrusion 11j. A clearance C is generated between them as shown in FIG. For this reason, a rattle sound is generated in an in-vehicle specification used in a vibrating environment. Furthermore, for example, as shown in FIG. 14, when the cover 12 is closed, the cover 12 may be tilted with respect to the cover holder 11 so that the right side is lowered, so that it looks strange.

  Since only one end of the cover 12 is locked by the cover holder 11, it is necessary to provide an elastic member for pressing the other end on the operation panel arranged around the cover holder 11. For this reason, there was a problem that the number of parts and the number of assembling steps increased and the manufacturing cost increased.

  According to the opening / closing structure of the opening / closing lid disclosed in Japanese Patent Application Laid-Open No. 2007-48916, the engaging protrusion 81 extending in a direction perpendicular to the sliding direction provided on the opening / closing lid 5 that slides the working opening 13 in the vertical direction to open / close. And the latching convex portion 82 and the latching convex portion 83 provided on the upper and lower sides of the left and right edge surfaces 131, 131 of the working opening 13 are locked, respectively, so that the opening / closing lid 5 is held in the closed position or the opened position. The

  In this opening / closing structure of the opening / closing lid, the latching convex portion 81 is elastically deformed and gets over the latching convex portion 82 or the latching convex portion 83, whereby the opening / closing lid 5 is positioned at the closed position or the open position. Since the deforming span is extremely short, it is difficult to set the dimensions of the hooking projections 81 to 83 in order to obtain an appropriate elasticity, and high dimensional accuracy in manufacturing is required. Mold design is difficult and manufacturing costs are high.

In addition, since the opening / closing lid 5 is locked only at the upper edge or only at the lower edge and the other edge is free, for example, in a vehicle-mounted specification used in a vibrating environment, there is a problem that rattle noise is generated. is there.

  The cover 2 shown in FIGS. 1 to 6 covers a USB connector or the like of a printed circuit board disposed behind the operation panel, and is opened when an external device is connected to the USB connector or the like. The cover holder 1 that guides the cover 2 is fastened to a chassis that supports the printed circuit board, but a screw insertion hole for fastening the cover holder 1 is not shown. An operation panel is arranged around the cover holder 1, but the operation panel is not shown.

  As shown in FIG. 2, a rectangular window 1m and a circular window 1n are formed on the front plate of the cover holder 1 to expose the USB connector and the like when the cover 2 is opened. On both sides of the cover holder 1, an upper side plate 1a and a lower side plate 1b are erected on the same plane, and a cover 2 is disposed between the side plates so as to be freely opened and closed.

  The upper side plates 1a and 1a of the cover holder 1 are formed with arc-shaped sliding contact surfaces 1c and 1c, respectively, extending from the lower side plate 1b and the upper side plate 1a so as to cover both ends of the sliding contact surface 1c. Are formed with an open side hinge 1d and a closed side hinge 1f. The lower plate 1b is further formed with an intermediate hinge 1e extending in the direction opposite to the open hinge 1d. An open-side convex portion 1g and a closed-side convex portion 1j are formed at the distal ends of the open side hinge 1d and the closed-side hinge 1f, respectively, and a first intermediate convex portion 1h is formed at the distal end portion of the intermediate hinge 1e.

  Side plates 2a and 2a adjacent to the upper side plates 1a and 1a of the cover holder 1 are formed on both sides of the cover 2, and the lower slidable contact surface 2b and the upper slidable contact are formed on an arc-shaped member extending vertically from the side plate 2a. Surface 2c is formed. A cover closing convex portion 2d and a cover opening convex portion 2e are formed in the vicinity of both ends of the upper sliding contact surface 2c. When the cover 2 is opened and closed, the lower slidable contact surface 2b is in slidable contact with the slidable contact surface 1c of the cover holder 1, and the upper slidable contact surface 2c is the open side convex portion 1g, the closed side convex portion 1j of the cover holder 1 or It is in sliding contact with the first intermediate protrusion 1h.

  As shown in FIGS. 2 and 4, in the open state of the cover 2, the cover 2 is slid to the lower end position with a finger, and the open side convex portion 1 g of the cover holder 1 is the cover open side of the cover 2. As shown in FIGS. 4 and 6 (a), the projection 2e is overcome and pressed against the inclined portion of the cover opening-side projection 2e to press the cover 2 in the opening direction. The cover 2 is pressed against the open-side stopper surface 1p of the cover holder 1, and the first intermediate convex portion 1h and the cover close-side convex portion 2d of the cover holder 1 are strongly pressed as shown in FIG. The cover 2 comes into contact with the cover holder 1 and is firmly fixed.

  As shown in FIGS. 1 and 3, in the closed state of the cover 2, the cover 2 is slid to the upper end position with a finger, and the closed convex portion 1 j of the cover holder 1 is the cover closed side of the cover 2. As shown in FIG. 3 and FIG. 5A, the projection 2d is brought into contact with the inclined portion of the cover close-side projection 2d and pressed in the direction in which the cover 2 is closed. The cover 2 is pressed against the closing side stopper surface 1q of the cover holder 1, and the first intermediate projection 1h and the cover opening side projection 2e of the cover holder 1 are strongly pressed as shown in FIG. The cover 2 comes into contact with the cover holder 1 and is firmly fixed.

  When the cover is closed or opened as described above, the convex portion of the hinge provided on the cover holder 1 overcomes the convex portion provided on the cover sliding contact surface. Can be easily recognized that the cover 2 has moved to the sliding end position.

  And although the cover 2 is fixed in the pressure contact state at both ends in the open state and the closed state, since each hinge extends in the direction of each sliding contact surface, it is elastically deformed without being twisted with respect to the sliding contact surface. The convex portions of the hinges are deformed so as not to incline with respect to the sliding contact surface, and the convex portions are pressed against the sliding contact surface without hitting each other. As a result, rattle noise does not occur even when used in a vibration environment. Furthermore, the cover 2 does not tilt with respect to the cover holder 1 when the cover 2 is closed.

  In addition, the span in which each hinge is elastically deformed can have a sufficient length, and an appropriate pressure contact force can be obtained stably in terms of dimensional design. Since high dimensional accuracy in manufacturing is not required, the design of the resin component molding die is easy, and the manufacturing cost is reduced.

  Further, since the cover 2 is held only by the cover holder 1, there is no need to hold the governor 2 with another member such as an operation panel, and it is only necessary to attach a module in which the cover 2 and the cover holder 1 are assembled. Thus, the number of parts and assembly man-hours are reduced, and the manufacturing cost is reduced.
