JP 2009-138407 A JP 2011-12543 A

  As described above, in the lock mechanism of the storage device for automobiles described in Patent Documents 1 and 2, all of the rod-shaped lock members that serve as lock devices that advance and retreat in the vehicle width direction are disposed on the opening / closing lid. The engagement holes (lock holes) with which the device engages are all arranged on the side wall surface of the storage portion provided on the vehicle main body side. That is, in the inventions described in Patent Documents 1 and 2, a rod-shaped lock member that moves forward and backward in the vehicle width direction is provided on the opening / closing lid that rotates back and forth, and the tip lock piece of this lock member is engaged and disengaged. An engagement / disengagement hole (lock hole) is formed on the side of the storage device main body, which is an immobile fixing part.

  In addition to the combined movement of the arc motion in the direction orthogonal to the lock material and the linear reciprocating motion in the length direction of the lock material, the rod-shaped lock material provided on the open / close lid Therefore, a stable and quiet engagement / disengagement operation to the lock hole at a relatively fixed position is forced. For this purpose, high precision and processing are required throughout the design, assembly, and mounting of the lock member and the lock hole, which may lead to an increase in cost.

  In the invention described in Patent Document 1, as shown in FIGS. 6A and 6B, the lock patch member 40 constituting the lock hole 48 includes an inclined portion 47B, A tongue piece 44 having a contact portion 48B extending horizontally is formed following the inclined portion 47B. If the tongue piece portion 44 is formed in this way, or if a gap is left between the tip lock piece and the lock hole, the tongue is caused by the vibration of the vehicle that occurs when the engine is idling or running. The piece 44 may vibrate to generate abnormal noise, or abnormal noise may be generated between the tip lock piece and the engagement / disengagement hole. Especially in luxury cars, there is a strong tendency to dislike even the slightest noise at such times.

  In order to avoid this, if a shock absorbing member such as urethane, sponge or felt is attached to the front end side of the lock hole 48 or the lock rod 38, the generation of abnormal noise can be prevented, but the material cost and processing cost increase. As a result, the number of work steps increases, resulting in an increase in manufacturing costs.

  The present invention has been developed in view of such circumstances, and its specific purpose is that the structure of an automobile accessory storage device is simple, its design, assembly, and workability are excellent, and the lid is closed. When operating or when the open / close lid is closed, due to the vibration of the vehicle that occurs when the engine is idling or running, the lock material collides with the lock hole to generate an abnormal noise (lower sound). An object of the present invention is to provide a locking mechanism that prevents the locking.

The object is provided in a storage device in a vehicle having a storage device main body for storing articles having an opening and an opening / closing lid for opening and closing the opening of the storage device main body, which is a basic configuration of the present invention. A lock mechanism that maintains the closed state of the open / close lid when the open / close lid is closed, wherein the storage device body has a slide member that can be advanced and retracted in the locking direction of the open / close lid,
The opening / closing lid has a locking / disengaging member that protrudes and is fixed on a rear surface of the opening / closing lid in a closing direction of the opening / closing lid and engages / disengages with a front end locking portion of the sliding member, and the sliding member includes the opening / closing lid. Elastically urged in the locking direction, and has a tapered surface at the distal end locking portion, and the engagement / disengagement member of the opening / closing lid has an inner circumferential surface in surface contact with the distal outer peripheral surface of the slide member. It is characterized by comprising a hole structure having one receiving surface portion and a second receiving surface portion having a tapered shape slidably contacting the tapered surface of the tip locking portion of the slide member.

  According to a preferred aspect, a cushion material is provided around the opening of the storage device main body, and the tapered surface of the front end locking portion of the slide member is formed toward the rear of the passenger compartment. preferable. Further, an arc in which at least one sliding contact surface of each sliding contact surface between the front end locking portion of the slide member and the engagement / disengagement member of the opening / closing lid projects to the other side during the closing operation of the opening / closing lid. It should be a surface.

  In the basic configuration of the present invention, a slide member that advances and retreats in the vehicle width direction is provided in a storage device main body arranged at a fixed position of the vehicle, and an engagement / disengagement member that engages / disengages a tip locking portion of the slide member Because it is fixed and protrudes in the closing direction from the back of the lid, it is easy to engage with the slide member if there is little design burden, and it can be moved in a unique way without stopping the processing accuracy. The removal member moves in synchronism with each other, and the opening / closing lid is securely locked without causing an abnormal sound (lower sound) due to collision between the two members.

  According to the above basic configuration of the present invention, the engagement / disengagement portion of the engagement / disengagement member protruding from the opening / closing lid has the lock hole structure, and the lock hole receives the outer peripheral surface of the tip engagement portion of the slide member. Since the first receiving surface portion and the second receiving surface portion that receives the tapered surface of the tip locking portion of the slide member are integrally formed, the first receiving surface portion and the second receiving surface portion are bent or distorted. There is nothing.

  Further, according to a preferred aspect of the present invention, the cushioning member is provided on the surface of the storage device body on the side of the passenger compartment, the tapered surface of the front end locking portion of the slide member is directed toward the rear of the passenger compartment, The direction of the tapered surface that is the second receiving portion of the lock hole formed in the removal member is formed so as to face the front of the vehicle when the opening / closing lid is closed. That is, the taper surface of the front end locking portion of the slide member and the taper surface which is the second receiving portion of the lock hole of the engagement / disengagement member of the opening / closing lid are formed with a phase difference of 180 °.

  In this case, the taper surface of the slide member is initially inserted into the lock hole formed in the engagement / disengagement member of the opening / closing lid by the biasing force of the slide member's leading end locking portion that is always biased in the locking direction. Moves to the back of the lock hole in surface contact with the inner tapered surface of the lock hole. At this time, simultaneously compressing and compressing the cushion material in which a part of the peripheral edge of the back surface of the opening / closing lid is attached to a part of the peripheral edge of the opening of the storage device main body, the reaction force and the urging force The resultant force acts on the distal end locking portion of the slide member via the second receiving portion on the inner surface of the lock hole of the engagement / disengagement member. According to a preferred aspect, the first receiving surface portion is a part of a cylinder, and the second receiving surface portion is a tapered surface formed in a direction intersecting with the first receiving surface portion. The internal taper surface (second receiving surface portion) of the lock hole is a taper surface formed with a 180 ° phase difference from the taper surface of the tip locking portion of the slide member. The resultant force acting on the first receiving surface portion is transmitted to the taper surface of the tip locking portion of the slide member, and the slide member is further pushed toward the back of the lock hole with a force greater than the urging force to lock the tip locking portion and the lock. The open / close lid is completely locked while maintaining a tightly-fitted state with no gap between the sliding contact surfaces with the holes. At the time of locking, even if vehicle vibration occurs during idling or running of the engine, the slide member and the engagement / disengagement member do not collide to generate an abnormal sound (lower sound).

  Further, according to the present invention, the tapered shape of the tip of the slide member is used to make the outer peripheral shape of the distal end portion of the engagement / disengagement member protruding in the closing direction from the back surface of the closing lid into a curved shape that bulges outward. Or the taper surface of the engagement member is attached to the tip taper surface of the slide member that is biased in the locking direction when the opening / closing lid is closed. Can be slid in a point contact state. The sliding resistance at this time is significantly reduced as compared with the sliding resistance due to surface contact, and the opening / closing operation of the opening / closing lid is performed more smoothly.

The in-hole tapered surfaces 122a-2 ″ and 122b-2 ″ are formed so as to face the front of the vehicle when the opening / closing lid 120 is closed.

In this case, the locking piece portions 112a-1 "and 112b-1" of the first and second slide members 112a and 112b that are always urged in the direction of the lock holes 121a and 122a are caused by the urging force in the extending direction. In the initial stage of insertion into the lock holes 121a, 122a formed in the engaging / disengaging members 121, 122 of the opening / closing lid 120, the respective tapered surfaces 112a-2 ", 112b- of the first and second slide members 112a, 112b are inserted. 4 is a close fitting state in which the in-hole tapered surfaces 122a-2 ", 122b-2" and the in-hole cylindrical surfaces 121a-1 ", 121b-1" of the lock holes 121a, 122a are in close contact with each other. In this way, it moves to the back of the lock holes 121a and 122a. During this movement, the cushioning material 115a, 115b whose back surface of the opening / closing lid 120 is stuck to the peripheral edge of the opening 110a of the box body 110 is compressed and deformed at the same time, and the reaction force f ₁ and the attached force are also applied. The resultant force in the horizontal direction with the force f ₂ is the first and second slide members 112a, 112b via the in-hole cylindrical surfaces 121a-1 ″, 121b-1 ″ of the lock holes 121a, 122a of the engagement / disengagement members 121, 122. It acts on the locking piece portions 112a-1 ″ and 112b-1 ″ of each of the leading end locking portions. The resultant force acting on the in-hole cylindrical surfaces 121a-1 ", 121b-1" is a tapered surface 112a-2 "of the locking piece portions 112a-1", 112b-1 "of the first and second slide members 112a, 112b. , 112b-2 ″, and the slide member is pushed toward the back of the lock hole with a force exceeding the urging force f ₂ , and between the sliding contact surface between the tip locking portion (locking piece portion) and the lock hole The open / close lid 120 is completely locked while maintaining a tightly fitting state without any gap. Even when the engine is idling or running, the slide members 112a and 112b and the engagement / disengagement members 121 and 122 collide with each other to generate an abnormal sound (lower sound). Absent.

In the above embodiment shown in FIGS. 1 to 4, the tip tapered surfaces 112 a-2 ″ and 112 b-2 ″ of the first and second slide members 112 a and 112 b have been described as planes. As shown in FIG. 5, the in-hole taper of the engaging / disengaging members 121 and 122 projecting from the back surface of the closing lid 120 by using the tip tapered surfaces 112a-2 "and 112b-2" of the slide members 112a and 112b. The surfaces 122a-2 ", 122b-2" are curved in such a manner that they bulge outward (the other side) in an arc shape, and the tip tapered surfaces 112a of the respective 112a, 112b urged in the locking direction when the opening / closing lid 120 is closed. −2 ″, 112b-2 ″ are convex curved surfaces that swell outward (the other side), thereby sliding on the in-hole tapered surfaces 122a-2 ″, 122b-2 ″ of the engagement / disengagement members 121, 122. When to be, the tip end tapered surface 112a-2 ", 112b-2" will be slid in a point contact state with the engaging member 121 and 122. The sliding resistance at this time is significantly reduced as compared with the sliding resistance due to surface contact, and the opening / closing operation of the opening / closing lid is performed more smoothly. The sliding contact surfaces (tapered surfaces) between the tapered end surfaces 112a-2 ", 112b-2" of the slide members 112a, 112b and the in-hole tapered surfaces 122a-2 ", 122b-2" of the engaging / disengaging members 121, 122 are shown. It is good also as a circular arc surface from which at least one sliding contact surface of a surface protrudes to the other side. Moreover, although each slide member used the rod-shaped thing, plate shape may be sufficient.
Moreover, although the opening part of the storage apparatus main body in a vehicle was provided in one surface (rear wall surface), you may provide over two surfaces, a rear wall surface and a top plate.
As described above, the present invention is not limited to the above embodiment, and various modifications are possible.
