Description

  The present invention relates to an assembly structure of a cover that accommodates a vehicle locking device or the like.

  A lock device for keeping the vehicle in a closed state is mounted on a vehicle entrance / exit door, a trunk for storing luggage, and a hatchback door. Some of the locking devices are covered with a theft prevention cover in order to prevent unauthorized operation from the outside.

Prior art document information related to this cover assembly structure includes the following.
Japanese Patent Laying-Open No. 2004-251106 (see FIGS. 2 and 7)

  The cover described in Patent Document 1 includes a pair of case halves, a claw portion projecting from one first case half, and a locking piece having a locking hole in the other second case half. Is protruding. Thus, when assembling them, the engaging pieces are fitted to each other, so that the engaging pieces are elastically bent outward by abutting the claw portions, and the engaging holes of the engaging pieces are nail. When it is coincident with the portion, the locking piece is restored inward to maintain the locking with the claw portion.

  However, this cover can release the lock with the claw portion by bending the lock piece outward by inserting a tool into the tip of the lock piece over the claw portion. There is a possibility that it will be removed illegally. Here, in order to surely prevent this unauthorized removal, it is conceivable to fix the pair of case halves in a non-removable state. However, in this case, it is difficult to disassemble the cover, and this is not preferable in recent years when it is desired to recycle the predetermined parts after use.

  The present invention has been made in view of conventional problems, and an object of the present invention is to provide a cover assembly structure that is easy to assemble and difficult to disassemble.

  In order to solve the above problems, a cover assembly structure according to the present invention includes first and second cover members, and these cover members are assembled together to form one cover. A locking receiving portion having a through-hole penetrating along the assembly direction of the second cover member is provided on a side surface of the member, and the second cover member is provided along the assembly direction with respect to the first cover member. A pair of projecting piece portions that project through the through hole, a claw portion projecting outward from the projecting piece portion, penetrating the through hole and locking to an edge of the through hole, and It is set as the structure which provided the resin-made latching | locking part which has a connection part which connects between front-end | tips.

  According to this cover assembly structure, when the second cover member is fitted to the first cover member, the locking portion is inserted into the through hole, and the claw portion comes into contact with the edge of the through hole. In this state, the claw portion is pressed inward at the inner edge of the through hole, and the claw portion enters the through hole in a state where the pair of projecting pieces are bent inward. Then, when the claw part exceeds the tip end edge in the assembling direction in the through hole, the inward pressing of the claw part is released, so that the projecting piece part is elastically restored, and the claw part of the locking part Is locked to the edge of the through hole.

  On the other hand, when the cover is disassembled during maintenance, the pair of projecting pieces are bent inward by moving inward so as to sandwich the claw portion that penetrates the through hole in the locking portion. And it presses in the reverse direction (detachment direction) with the assembly | attachment, maintaining this state. As a result, the pair of claw portions can be caused to enter the through hole and the locking can be released. At this time, in the present invention, the pair of projecting pieces are connected to each other between the tips by the connecting portion, and thus the claw portion cannot be easily moved inward. Therefore, a dedicated tool is required.

  Thus, in the present invention, at the time of assembly, it is only necessary to allow the locking portion to pass through the through-hole, and the pair of protruding piece portions are connected by the connecting portion, and the locking receiving portion is displaced between the protruding piece portions. Since it does not fit, workability is good. And since a connection part makes the role which makes the width | variety of two claw parts constant, an engagement allowance can be stabilized. That is, when the connecting portion is not provided, distortion may occur during molding and the protruding piece portion may be inclined, and in this case, the engagement allowance becomes insufficient and easily disengages, but such a problem may occur. Absent. In addition, since the projecting piece can be elastically deformed along the side surface of the first cover member, it is possible to absorb the lateral displacement between the first cover member and the second cover member during assembly, and also to variations in molding errors. Can be easily handled.

  On the other hand, when disassembling, it is necessary to press both claw parts inward simultaneously. When one claw part is pressed from the side, the other claw part is locked via the connecting part. Because it strengthens, it can achieve a cover that is extremely difficult to disassemble. As a result, for example, in an assembled state in a vehicle, even if a tool or the like is hooked on the engaging portion to try to disassemble it illegally, it cannot be disassembled, so that unauthorized removal can be reliably prevented.

  In this cover assembly structure, the latch receiving portion includes a pair of projecting portions projecting from the side surface of the first cover member, and a continuous portion extending between the tips of the projecting portions, and the through hole includes these It is preferable that the protrusion and the continuous portion are surrounded by the side surface. If it does in this way, since the latching | locking part will be in the state along the side surface in the assembly | attachment state, since workability | operativity which presses a pair of nail | claw part inward will become very bad, an unauthorized disassembly can be prevented reliably.

  In the cover assembly structure of the present invention, the first cover member is provided with the latch receiving portion, the second cover member is provided with the latch portion, and the latch portion is composed of the pair of projecting piece portions, the claw portion, and the connecting portion. Since it is configured, the workability at the time of assembly is good, but a cover that is extremely difficult to disassemble can be realized. Therefore, disassembly for the purpose of maintenance and recycling is possible, but unauthorized removal (disassembly) can be reliably prevented.

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

  1 to 5 show a cover 10 to which a cover assembly structure according to an embodiment of the present invention is applied. The cover 10 is used to prevent unlocking by an unauthorized operation by being assembled to the lock device 1 mounted on the hatchback door of the vehicle. The first to third resin cover members 11, 22, and 29 are attached to the cover 10. I have.

  First, the lock device 1 for assembling the cover 10 of the present invention will be described.

A fork 6 and a claw 7 are rotatably attached to the second base plate 5.

  When the back door is closed, the striker fixed on the vehicle body side enters the groove 6a of the fork 6 to rotate the fork 6 against the urging force of a urging spring (not shown). Then, the fork 6 is stopped at the fixed position to maintain the closed state. On the other hand, when the user operates a key cylinder (not shown), the operation lever 3 is rotated clockwise in FIG. As a result, the operating lever 3 is locked to the open lever 4, and the open lever 4 is rotated counterclockwise, whereby the claw 7 is rotated clockwise in FIG. As a result, the lock between the claw 7 and the fork 6 is released, and the holding of the striker is released. In the figure, reference numeral 9 denotes a spacer disposed in the second base plate 5.

  The cover 10 of the present invention covers the operation lever 3 and the open lever 4 for releasing the lock in the locking device 1 with the first and second cover members 11 and 22 and covers the second base plate 5 in the first state. The three cover members 29 are configured to cover.

  Specifically, as shown in FIGS. 1 and 2, the first cover member 11 is assembled to an inner portion of a bent portion 2 a bent in a substantially L shape in the first base plate 2. The first cover member 11 is provided with a mounting hole portion 12 on a mounting surface located on the back side. At the edge of the mounting hole 12, a hooking portion 13 is provided to be hooked and locked to the upper edge of the bent portion 2a, and a pair of locking claws 14 are provided at the side edge. In addition, a screwing portion 15 for fixing to the first base plate 2 by screwing is provided inside the mounting hole portion 12. Furthermore, an insertion hole 16 is provided in the side surface 11a of the first cover member 11 so as to penetrate the rod 8 and connect to the internal operation lever 3. The first cover member 11 is provided with a shielding portion 17 that extends from the front assembly surface side to which the first cover member 11 is assembled toward the back surface and shields the lower open lever 4. ing.

  And the 1st cover member 11 of this embodiment makes the opening part upper part from the shielding part 17 the assembly surface of the 2nd cover member 22, and it is three on the side surface 11a which comprises the edge of the assembly surface. A locking receiving portion 18 is provided. These locking receiving portions 18 include a pair of projecting portions 19 and 19 projecting from the side surface 11 a and a continuous portion 20 extending between the tips of the projecting portions 19 and 19. And the internal space enclosed by these protrusion parts 19 and 19, the continuous part 20, and the side surface 11a comprises the through-hole 21 which penetrates and latches the latching | locking part 25 mentioned later along an assembly direction.

  Note that the first cover member 11 of this embodiment is manufactured by injection molding in which a resin material is poured into a cavity of a housing formed by a fixed mold and a movable mold. And since the protrusion part 19 and the connection part 20 which comprise the latching receiving part 18 make the structure extended along the side surface 11a, they can be manufactured with the fixed mold and movable mold which open and close along the side surface 11a. It is possible and there is no need to use a separate slide mold or the like. Therefore, the manufacturing cost can be reduced.

  The second cover member 22 is a plate having a substantially inverted L shape that matches the outer shape of the assembly surface of the first cover member 11. In addition, this 2nd cover member 22 has comprised the shape bent so that the shape of the assembly | attachment surface might be sealed so that the assembly | attachment surface of the 1st cover member 11 might be sealed. The second cover member 22 is provided with a fitting rib 23 that is fitted to the inner surface of the side wall 11 a of the first cover member 11. A projecting plate portion 24 for adjusting the opening shape of the insertion hole 16 is provided at a position corresponding to the insertion hole 16.

  The second cover member 22 of the present embodiment is provided with a locking portion 25 for maintaining the assembled state through the through hole 21 of the locking receiving portion 18. The locking portion 25 includes a pair of projecting piece portions 26 and 26 projecting along the assembly direction to the first cover member 11, and a claw portion 27 projecting outward from the projecting piece portions 26 and 26. 27 and a connecting portion 28 for connecting the tips of the projecting piece portions 26 and 26 to each other. Among them, as shown in FIGS. 3 and 4, the projecting piece portions 26, 26 have dimensions that penetrate the through hole 21 from the assembly surface side and project forward from the through hole 21 in the assembly direction. In addition, the dimension between the outer surfaces is formed substantially the same as the dimension in the width direction between the inner surfaces of the pair of protrusions 19 in the through hole 21. The claw portions 27 and 27 are formed in a portion protruding from the through hole 21 in a state where the second cover member 22 is in surface contact with the assembly surface of the first cover member 11, and in this state, is an edge of the through hole 21. The protrusion 19 is locked to the front end surface in the assembly direction. The connecting portion 28 has an arc shape, and the width direction that is the direction of the adjacent protruding piece portions 26 and 26 in order to be able to bend the connected protruding piece portions 26 and 26 inward (flexibility). The wall thickness is thin. Specifically, the thickness of the connecting portion 28 is set to about 1/3 with respect to the thickness in the pair of width directions of the pair of projecting piece portions 26 and 26 that can be bent inward. Yes.

  Note that the second cover member 22 of the present embodiment is manufactured by injection molding in which a resin material is poured into a cavity of a housing formed by a fixed mold and a movable mold, similarly to the first cover member 11. . And the position of the edge part of the 2nd cover member 22 corresponding to the protrusion direction of the latching | locking part 25 with respect to the nail | claw part 27 and the connection part 28 which comprise the latching | locking part 25 is a fixed mold or a working mold. A mold escape portion 22a (see FIG. 1) is provided so that the mold can be removed. Therefore, the locking part 25 of the present embodiment can be manufactured by a fixed mold and a movable mold that open and close in the protruding direction of the locking part 25, and it is not necessary to use a slide mold or the like separately. . Therefore, the manufacturing cost can be reduced. The locking portion 25 is provided so as to protrude further outward from the edge of the second cover member 22, and corresponds to the protruding direction of the locking portion 25 with respect to the claw portion 27 and the connecting portion 28 of the locking portion 25. By setting the position to the outside of the edge of the second cover member 22, it is possible to manufacture with a fixed mold and a movable mold that open and close in the protruding direction of the locking portion 25 without providing the escape portion 22a. is there.

  The third cover member 29 serves as a buffer member interposed between the second base plate 5 and the vehicle body when the second base plate 5 is assembled to the vehicle body. As shown in FIG. 5, the third cover member 29 includes a covering portion 30 that covers the second base plate 5. The covering portion 30 is provided with a screw insertion hole 31 corresponding to the screw insertion hole 5a of the second base plate 5. Further, the third cover member 29 is provided with a cylindrical protrusion 32 that covers the exposed portion of the lower side of the first cover member 11 in a state where the first cover member 11 is assembled to the first base plate 2. Yes.

  When the cover 10 configured as described above is assembled to the lock device 1, first, as shown in FIG. 8, first, the third cover member 29 is covered from the upper side of the first base plate 2 to cover the second base plate 5. .

  Next, the first cover member 11 is disposed from the front side where the operation lever 3 is disposed. Then, in a state where the hook portion 13 is hooked on the upper end edge of the first base plate 2, the first cover member 11 is pressed against the first base plate 2, whereby the locking claw portion 14 is moved to the side edge of the first base plate 2. To lock. In this state, a screw is fastened and fixed to the screw fixing portion 15 from the back side of the first base plate 2 through the screw hole 2b provided in the bent portion 2a of the first base plate 2. Further, the tip of the rod 8 connected to the key cylinder from the insertion hole 16 of the first cover member 11 is inserted inside, and is connected to the operation lever 3 so as to be rotatable.

  Finally, as shown in FIG. 9, the second cover member 22 is assembled to the first cover member 11 to form one cover 10. Specifically, the second cover member 22 is fitted to the assembly surface of the first cover member 11. At this time, the locking portion 25 is inserted into the through hole 21 of the locking receiving portion 18. This insertion operation can be easily performed by the connecting portion 28 having a tapered shape. When the distal end of the locking portion 25 is inserted into the through hole 21, the claw portions 27 and 27 are then brought into contact with the edge of the projecting portions 19 and 19 that are the edges of the through hole 21 in the assembling direction. In this state, by pressing the second cover member 22 toward the first cover member 11, the claw portions 27 and 27 are pressed inward at the inner edge of the through hole 21. As a result, the pair of protruding pieces 26 and 26 bend inward, and the claw portions 27 and 27 enter the through hole 21 in this state. Then, when the claw portions 27 and 27 pass through the end of the assembly direction in the through-hole 21 and completely pass (penetrate), the inward pressing of the claw portions 27 and 27 is released, whereby the projecting piece portion 26 and 26 is elastically restored. As a result, the claw portions 27 and 27 of the locking portion 25 are locked to the protruding portions 19 and 19 that are the edges of the through hole 21.

  Thus, in the present invention, the second cover member can be assembled to the first cover member 11 simply by fitting the locking portion 25 so as to penetrate the through hole 21. Moreover, since the pair of projecting piece portions 26 and 26 are connected by the connecting portion 28, the protruding portion 19 of the locking receiving portion 18 is not fitted in between the projecting piece portions 26 and 26. Therefore, workability at the time of assembly is extremely good.

  In the assembled cover 10, the connecting portion 28 of the second cover member 22 serves to make the widths of the two claw portions 27, 27 constant, so that the edge of the through hole 21 of the first cover member 11. The engagement allowance can be stabilized. That is, when the connecting portion 28 is not provided, distortion may occur during molding and the projecting piece portions 26 and 26 may be inclined. In this case, the engagement margin becomes insufficient and the disengagement easily occurs. Will not occur. Further, since the projecting piece portion 26 can be elastically deformed along the side surface 11a of the first cover member 11, it is possible to absorb a lateral shift between the first cover member 11 and the second cover member 22 during assembly, and molding is performed. Can easily handle error variations.

  On the other hand, when disassembling the cover 10 at the time of maintenance or recycling, the pair of projecting pieces are moved inward by sandwiching the pair of claw portions 27, 27 penetrating the through hole 21 at the locking portion 25. The portions 26 and 26 are bent inward. And while maintaining this state, it is pressed in the opposite direction (detachment direction) from the time of assembly. Thereby, each nail | claw part 27 and 27 can be entered in the through-hole 21, and latching can be cancelled | released. At this time, in the present invention, the pair of projecting piece portions 26 and 26 are connected to each other by the connecting portion 28, and thus the claw portions 27 and 27 cannot be easily moved inward. Therefore, a dedicated tool or the like is necessary.

  Thus, when removing (disassembling) the second cover member 22 from the first cover member 11, it is necessary to simultaneously press both the claw portions 27 and 27 inward. In other words, when one of the claw portions 27 is pressed from the side, the locking of the other claw portion 27 is strengthened via the connecting portion 28, so that the locking of the claw portions 27, 27 cannot be released. . Therefore, it is very difficult to disassemble the cover 10 in the assembled state. As a result, for example, in the state of being assembled in a vehicle, even if a tool or the like is hooked on the locking portion 25 and illegally disassembled, it cannot be disassembled, so that unauthorized removal can be reliably prevented.

  Moreover, in the present embodiment, the locking receiving portion 18 of the first cover member 11 is formed in a state in which the through hole 21 is surrounded by the protruding portions 19, 19, the continuous portion 20 and the side surface 11 a, so that the second cover In the assembled state of the member 22, the locking portion 25 is in a state along the side surface 11a. Therefore, since the workability of pressing the pair of claw portions 27 and 27 inward in this state is extremely poor, unauthorized disassembly can be reliably prevented.

  In addition, the cover assembly structure of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the embodiment, the lock receiving portion 18 and the lock portion 25 are provided in three places, but only one of the lock receiving portion 18 and the lock portion 25 is configured. The locking structure may be configured similarly to the conventional one. That is, another locking structure may be configured by a claw portion protruding from the side surface 11 a of the first cover member 11 and a locking piece protruding from the second cover member 22.
