Description

  The present invention relates to a mounting method and a mounting device for a vehicle exterior part for attaching a vehicle exterior part to a vehicle body.

  In recent years, a scratch-proof member, which is one of exterior parts for a vehicle that prevents damage when it comes into contact with an obstacle such as a bumper attached to the front or rear of a vehicle or a garnish attached to a side surface of the vehicle, is, for example, an injection Since it can be produced in large quantities at a low cost by a molding technique or the like, and the vehicle can be reduced in weight, it is formed of a resin material such as urethane or polypropylene. When these vehicle exterior parts are attached to a vehicle, the surface thereof constitutes the exterior of the vehicle together with the vehicle main body, so-called vehicle body.

  Specifically, a vehicle exterior component (hereinafter referred to as a flaw-proof component) 201 shown in FIG. 8 is attached to the vehicle body at a predetermined position on the back surface 201a facing the vehicle body 202 when attached to the vehicle body 202. A mounting portion 204 is provided on which a mounting member 203 such as a bolt, a hook, a tap, or the like for mounting on 202 is locked. The flaw-proof component 201 locks the mounting portion 204 and a locking portion 202a such as a screw hole or a mounting hole in which the mounting member 203 provided in the vehicle main body 202 is locked via the mounting member 203. Is attached to the vehicle main body 202, and the surface 201 b of the vehicle main body 202 constitutes the exterior of the vehicle.

  In addition to the scratch-proof component 201 for preventing damage, the vehicle exterior component includes a component for specifying the type of vehicle such as a mark or an emblem. As a method of attaching this member, there is a method of attaching an exterior part by so-called heat caulking, etc., in which an attachment part inserted into the vehicle main body 202 is melted from the back side, and the exterior part is locked using the melted part as a stopper (Patent Literature). 1).

  However, in the scratch-proof component 201 for preventing the damage described above, the meat between the portion provided with the mounting portion and the other portion at the position where the mounting portion 204 of the surface 201b constituting the exterior of the vehicle main body 202 faces. Since the thicknesses are different, there is a difference in the flow of the resin when formed by the injection molding technique, and a bowl-shaped dent, a so-called sink mark, may occur, resulting in poor appearance.

  In addition, when attaching the scratch-proof component 201 to the vehicle main body 202 by the method of attaching the exterior component by heat caulking as described in Patent Document 1, for example, the type of the vehicle that itself is lightweight, such as a mark or an emblem, is specified. Although it is effective as a method for attaching an exterior part or the like to the vehicle, the scratch-proof part 201 such as the bumper or the garnish described above is heavy in weight, so that the scratch-proof part 201 is melted by heat caulking. It becomes difficult to support the weight, and the attachment strength of the scratch-proof component 201 to the vehicle main body 202 may be weakened. Therefore, the trauma part 201 may come off from the vehicle body 202 due to a slight impact.

Hereinafter, a case where the front fender garnish 3c (hereinafter referred to as a fender garnish) is attached to the vehicle body 2 will be described as an example. When the present invention is applied to the fender garnish 3c, the fender garnish 3c is sufficiently prevented from coming off from the vehicle body 2 except when, for example, an abnormal impact is applied to the vehicle body 2 and / or the fender garnish 3c. can do.

  The fender garnish 3c has a main body portion 11. The main body portion 11 is provided with a locking piece 12 protruding substantially perpendicularly from a back surface 11a facing the vehicle main body 2. For example, a resin material such as urethane or polypropylene is used. The main body 11 and the locking piece 12 are integrally molded, and are formed by an injection molding technique or the like.

  The main body 11 is exposed to the outside when the surface 11b opposite to the back surface 11a provided with the locking piece 12 is attached to the vehicle main body 2, and the surface 11b together with the vehicle main body 2 constitutes the exterior of the vehicle. . For this reason, in the main body part 11, the same coating or the like as the coating of the vehicle main body 2 is applied to the surface 11b. The main body 11 may be made to stand out by making the surface 11b different from the exterior paint color of the vehicle main body 2 and accentuate the appearance design of the vehicle main body 2. Further, the main body 11 is provided with a bent portion 13 bent at a predetermined position so as to protrude toward the front surface 11b for causing the vehicle main body 2 to bulge, and thereby the front surface 11b It is also possible for the vehicle body 2 to be substantially integrated.

  The locking piece 12 is a flat plate integrally projecting from the main body, and one or a plurality of the locking pieces 12 are provided based on the attachment strength corresponding to the function of the fender garnish 3c. The locking piece 12 has a distance from the base end 12a to the leading end 12b, that is, a height from the so-called back surface 11a, when the mounting part 4 is locked to the fender garnish 3c. It is made higher than the front-end | tip 23b of the provided rib 23. FIG.

  Further, the locking piece 12 has a thickness that is at least thinner than the thickness of the main body 11. As a result, when the fender garnish 3c is formed by the injection molding technique, a difference occurs between the location where the locking piece 12 is disposed and the other location in the flow of the resin material, and the locking piece 12 on the surface 11b. It is possible to reduce a so-called sink mark, which is a saddle-like dent that occurs at a position opposite to.

  By disposing the locking piece 12 along the bent portion 13 provided in the main body portion 11, it is possible to make a sink mark caused by a difference in thickness in the main body portion 11 inconspicuous.

  In the fender garnish 3c configured as described above, the thickness of the locking piece 12 which is attached to the vehicle body 2 via the mounting part 4 and the stopper 5 described later and is used to lock the mounting part 4 is set to the main body part. By making it thinner than the thickness of 11, the sink marks generated when injection molding is performed on the surface 11 b of the main body 11 can be reduced, and by providing the bent portions 13, the sink marks can be made inconspicuous and the appearance of the surface 11 b is good. Can be.

  The attachment part 4 is located between the fender garnish 3c and the vehicle body 2 when the fender garnish 3c is attached to the vehicle body 2, and is not visible from the appearance. Therefore, unlike the fender garnish 3c, the attachment part 4 can be freely designed and arranged with a protruding piece or the like without worrying about sink marks.

  The attachment part 4 for attaching the fender garnish 3c to the vehicle main body 2 has a main body portion 21. The main body portion 21 has an insertion hole 22 through which the locking piece 12 of the fender garnish 3c is inserted, and this insertion. A rib 23 provided in a part or all of the periphery of the hole 22 and an attachment portion 24 to which a stopper 5 for attaching the main body portion 21 to the vehicle main body 2 is attached. The attachment part 4 is a body part 21, an insertion hole 22, a rib 23, and an attachment part 24 that are integrally formed of a resin material such as urethane or polypropylene, and is formed by an injection molding technique or the like.

  When the main body 21 is locked to the fender garnish 3c, the main surface 21a opposite to the fender garnish 3c is fixed to the fender garnish 3c so that the attachment part 4 can be locked to the fender garnish 3c without rattling. The main body portion 11 is overlaid so as to contact the back surface 11a.

  Further, the main body 21 is provided with a bulging portion 25 that bulges from one main surface 21a toward the other main surface 21b at least around the insertion hole 22. Thereby, in the attachment part 4, when locked to the fender garnish 3c, the base end 12a of the locking piece 12 inserted through the insertion hole 22 can be formed on the side of the main surface 21a of the bulging portion 25. 21 and the fender garnish 3c. Thereby, in the attachment component 4, since the base end 12a of the latching piece 12 inserted in the insertion hole 22 is arrange | positioned in the space 25a by the side of the one main surface 21a of the bulging part 25, for example, the below-mentioned melting When the locking piece 12 inserted through the insertion hole 22 by the means 41 is melted, it is possible to prevent the locking piece 12 from being melted up to the base end 12a by stopping only at the distal end 12b. Therefore, when the locking piece 12 is melted, it is possible to prevent the locking piece 12 from being melted to the base end 12a and the strength of supporting the fender garnish 3c of the locking piece 12 from being lowered.

  The insertion hole 22 through which the locking piece 12 of the fender garnish 3c is inserted is a through-hole provided in the thickness direction of the main body 21 and is at least opposed to the position facing the locking piece 12 of the fender garnish 3c. The same number as the stop piece 12 is provided. In the insertion hole 22, the size of the opening is substantially the same as the size of the outer periphery of the locking piece 12, and the locking piece 12 is inserted with little play. Specifically, a gap formed between the insertion hole 22 and the locking piece 12 is set to 0.1 mm or less, for example. Thereby, when the locking piece 12 is melted, for example, the molten locking piece 12 and the like pass through the gap between the locking piece 12 and the insertion hole 22 and between the main body 21 and the fender garnish 3c. Intrusion can be prevented, and a locking portion 51 described later can be enlarged.

  The ribs 23 formed around the insertion hole 22 are provided so as to protrude substantially perpendicularly from the other main surface 21b formed in a part or all of the periphery of the insertion hole 22 on the other main surface 21b side of the main body 21. Has been. The rib 23 protrudes at least from the insertion hole 22 when the locking piece 12 of the fender garnish 3c is inserted into the insertion hole 22 by a distance from the base end 23a to the distal end 23b, that is, a height from the other main surface 21b. It is made to become lower than the front-end | tip 12b of the latching piece 12 made. Further, the rib 23 has a thickness smaller than the thickness of the locking piece 12 of the fender garnish 3 c protruding from the insertion hole 22. The rib 23 serves as a reinforcing portion that reinforces the locking piece 12 when the locking piece 12 is welded and the fender garnish 3c and the mounting part 4 are integrated, and its thickness is made thinner than the thickness of the locking piece 12. Thus, the time required to weld the locking piece 12 is prevented from becoming excessively long.

  The mounting portion 24 includes a storage portion 24a into which the flange 31 of the stopper 5 is inserted and stored in order to lock the stopper 5 at a position facing the locking hole 2a disposed in the vehicle body 2. It is formed so as to cut out a part of the side wall of the storage portion 24a, and has a fitting groove 24b into which the shaft portion 32 of the stopper 5 is fitted. And the attachment component 4 attaches the main-body part 21 to the vehicle main body 2 by engaging the stopper 5 latched by the attachment part 24 in the engagement hole 2a of the vehicle main body 2, for example, by fitting. It becomes possible.

  The mounting part 4 having the above-described structure is mounted to the vehicle main body 2 via the stopper 5 locked to the mounting portion 24 when the main body portion 21 is locked to the fender garnish 3c. Thus, it functions as an attachment device for attaching the fender garnish 3c to the vehicle body 2.

  Since the attachment part 4 is an attachment device for attaching the fender garnish 3c to the vehicle body 2, it is not exposed to the outside. For example, the attachment part 4 is formed by injection molding technology and has marks on both main surfaces 21a and 21b of the body portion 21. If this happens, it will not be a problem. For this reason, in the attachment component 4, for example, the thickness of the resin member forming the attachment portion 24 to which the stopper 5 is locked can be increased, and the stopper 5 can be firmly locked to the attachment portion 24.

  In addition to the above-described configuration, the attachment part 4 includes, for example, a bending prevention rib 26 that protrudes substantially perpendicularly from the other main surface 21b of the main body 21 to suppress the main body 21 from being bent in the thickness direction. One or more are provided at predetermined positions. Since the sink mark does not become a problem, the thickness of the bending prevention rib 26 can be increased so as to further suppress the bending in the thickness direction of the main body 21. Furthermore, since the bending prevention rib 26 is attached in a state where the main surface 21a of the attachment part 4 is in contact with the back surface 11a of the fender garnish 3c when the attachment part 4 is attached to the fender garnish 3c, the fender garnish It is also suppressed that 3c bends in the thickness direction. That is, since it is not necessary to provide a portion such as the bending prevention rib 26 on the fender garnish 3c side, a difference in the thickness of the fender garnish 3c is suppressed, and generation of sink marks can be suppressed.

  The stopper 5 includes a substantially disc-shaped flange 31, a shaft portion 32 projecting substantially perpendicularly from a substantially center of the flange 31, and a pressing portion 33 disposed at an end portion of the shaft portion 32 opposite to the flange 31.

The stopper 5 is formed by integrally molding the flange 31, the shaft portion 32, the pressing portion 33, and the locking portion 34 with a resin material such as urethane or polypropylene, and is formed by an injection molding technique or the like.

  The flange 31 is inserted and stored in the storage portion 24a of the mounting portion 24 of the mounting member 4, and the stopper 5 locked to the mounting portion 24 is pulled out from the other main surface 21b of the main body portion 21 in a substantially vertical direction. It functions as a stopper that prevents this.

  The shaft portion 32 has a substantially cylindrical shape, a flange 33 is disposed at one end, and a pressing portion 34 is disposed at the other end. The distance from one end to the other end, that is, the so-called column height is the height of the mounting member 4. The thickness of the resin material of the attachment portion 24 is substantially the same, and the diameter of the cylinder is substantially the same as the width of the fitting groove 24 b of the attachment portion 24. The shaft portion 32 is inserted into the fitting groove 24b of the mounting portion 24 in a direction substantially orthogonal to the axial direction at the same time that the flange 31 is inserted into the storage portion 24a of the mounting portion 24. When the shaft portion 32 is fitted into the fitting groove 24b, the flange 31 is brought into contact with the inner peripheral surface of the side wall in the storage portion 24a, and the pressing portion 33 is brought into contact with the outer peripheral surface of the side wall in the storage portion 24a. Let Further, when the shaft portion 32 is inserted into the insertion groove 24b, the outer peripheral surface thereof is brought into contact with the inner surface of the insertion groove 24b.

  The pressing portion 33 has a substantially disk shape with the portion where the shaft portion 32 is disposed approximately as a center, and is disposed on the shaft portion 32 when the stopper 5 is locked to the vehicle body 2. The main surface opposite to the surface is shaped to bulge toward the shaft portion 32 so as to press the vehicle body 2. Further, the pressing portion 33 is made of, for example, sponge or rubber so that the vehicle main body 2 is not dented or damaged when pressed on the surface facing the vehicle main body 2, that is, the main surface pressing the vehicle main body 2. An elastic member 33a made of a resin material or the like is provided. And in the press part 33, rattling of the stopper 5 attached to the vehicle main body 2 can be prevented by pressing the vehicle main body 2.

  The locking portion 34 is a columnar member that protrudes in a substantially vertical direction from the approximate center of the main surface of the pressing portion 33 that presses the vehicle main body 2, and is inserted into a locking hole 2 a provided in the vehicle main body 2. . The locking portion 34 has a distal end and a base end made thinner than the inner diameter of the locking hole 2a of the vehicle body 2, and a portion between the distal end and the base end is made thicker than the inner diameter of the locking hole 2a. The locking portion 34 is configured to be elastically deformed inward toward a position where a portion thicker than the diameter of the locking hole 2a between the distal end and the base end is inserted through at least the locking hole 2a. ing. When the locking portion 34 is inserted into the locking hole 2a provided in the vehicle body 2 from the distal end toward the proximal end, a thick portion between the distal end and the proximal end is located inside the locking hole 2a. The stopper is elastically deformed by being pressed by the peripheral surface, and becomes a stopper that prevents the elastically deformed portion passing through the locking hole 2a from coming out of the locking hole 2a by restoring the original shape. When the locking part 34 is inserted into the locking hole 2a almost to the base end, the pressing part 33 presses the vehicle main body 2 by causing the thick part between the front end and the base end to function as a stopper. Can be retained.

  The stopper 5 configured as described above is configured so that the flange 31 and the pressing member 5 are pressed when the flange 31 is stored in the storage portion 24a of the mounting portion 24 by inserting the shaft portion 32 into the insertion groove 24b of the mounting portion 24 of the mounting component 4. Each of the portions 33 is brought into contact with the side wall of the storage portion 24a, and the outer peripheral surface of the shaft portion 32 is brought into contact with the inner surface of the fitting groove 24b, so that the mounting portion 4 is appropriately locked. Further, the stopper 5 is locked in a state in which the pressing portion 33 presses the vehicle main body 2 by inserting the locking portion 34 into the locking hole 2a provided in the vehicle main body 2, and there is no rattling. It is attached to the vehicle body 2.

  Specifically, as shown in FIG. 4, the locking piece 12 is inserted into the insertion hole 22 so that the back surface 11 a of the main body portion 11 of the fender garnish 3 c and the other main surface 21 b of the main body portion 21 of the attachment part 4 are in contact with each other. In a state in which the attachment part 4 is laminated on the fender garnish 3c so as to come into contact, the heated portion 41a is pressed against the tip 12b of the locking piece 12 and the tip 23b of the rib 23, whereby the tip of the locking piece 12 12b and the tip 23b of the rib 23 are melted together. Then, the molten mass in which the locking piece 12 and the rib are melted together becomes the locking portion 51 that prevents the locking piece 12 from coming out of the insertion hole 22, so that the attachment part 4 is appropriately engaged with the fender garnish 3 c. You can stop. That is, since the locking portion 51 is larger than the melted lump when only the locking piece is melted as in the prior art, the rib 23 in addition to the locking piece 12 also forms a molten lump so that, for example, Even if external stress is applied to the fender garnish 3c, the locking piece 12 is prevented from coming off from the insertion hole 23, and the mounting part 4 is appropriately locked to the fender garnish 3c. At this time, in the fender garnish 3c, when the locking portion 51 is formed, the rib 23 functions as a reinforcing portion for the locking piece 12 for forming the locking portion 51 large. It can be made thin, and the appearance of the mark can be improved by suppressing sink marks generated on the surface 11b.

Here, the attachment method of the conventional exterior apparatus is demonstrated as a comparative example. Specifically, the case where the car exterior part 101 and the mounting part 102 are integrated only by the locking piece 103, that is, the car exterior part 101 and the mounting part 102 without the ribs are integrated. explain. In the car exterior part 101, as shown in FIG. 7A, since the locking piece 103 is thinned so as not to cause a problem such as a sink mark, the locking piece 103 is inserted into the insertion hole 104 of the mounting part 102. The stopper 105 formed by melting the distal end side of the locking piece 103 becomes small in a state in which is inserted. In the car exterior part 101 integrated with the mounting part 102 in this way, as shown in FIG. 7B, since the stopper 105 is small, for example, vibration when the vehicle travels or travel of the vehicle The stopper 105 may come off from the insertion hole 104 and be detached from the mounting part 102 when subjected to stress from the outside, such as a stone hit by a tire or the like hitting it inside. It becomes difficult to keep. Further, in the conventional mounting method of the vehicle exterior part, since the mounting part 102 is not provided with ribs, the stopper 105 cannot be made large. For example, the vehicle exterior part 101 and the mounting part 102 are It becomes difficult to integrate without rattling. For example, in the conventional method for mounting an exterior part for a vehicle, the stopper 105 can be prevented from coming out of the insertion hole 104 by increasing the thickness of the locking piece 103 and increasing the formed stopper 105. However, in this case, since the thickness of the locking piece 103 is increased, there is a difference in the flow of the resin material when the injection molding is performed, and there is a possibility that a sink mark is generated in the vehicle exterior part 101.

  Also from this, in order to enlarge the locking part 51 and to make the locking piece 12 thinner, it is possible to dispose the ribs 23 in part or all of the periphery of the insertion hole 22 in the mounting member 4. It can be seen that the mounting strength of the vehicle exterior component 3 with respect to 2 is high, and it is very effective in obtaining the vehicle exterior component mounting device 1 that prevents the occurrence of sink marks on the surface 11 b of the vehicle exterior component 3.

  Further, when forming the locking part 51, the time for pressing the heating part 41 a against the locking piece 12 and the rib 23, the heating temperature by the heating part 41 a, etc. are adjusted to melt the base end 23 a side of the rib 23. It is made to leave without making it the latching | locking part 51 which is a molten lump so that the base end 23a of the rib 23 may be covered. As a result, as shown in FIG. 5, the attachment part 4 is configured such that the base end 23 a of the rib 23 bites into the surface of the locking portion 51 that is a molten mass on the main body portion 21 side, and the locking portion 51 is inserted. It can be prevented from coming out of the hole 22, and the locking piece 12 can be prevented from moving in the insertion hole 22, and is locked and integrated with the fender garnish 3c without rattling.

Then, the attachment part 4 which is integrated with the fender garnish 3c, as shown in FIG. 6, the flange 31 of the mounting part 4 into the fitting groove 24b by fitting the shaft portion 32 of the attachment part 4 of the mounting portion 24 The attachment component 4 is attached to the attachment portion 24 by being accommodated in the accommodation portion 24a.

  Next, the locking portion 34 of the stopper 5 locked to the mounting portion 24 of the mounting component 4 integrated with the fender garnish 3 c is inserted into the locking hole 2 a provided in the vehicle body 2. At this time, in the stopper 5, the pressing portion 33 presses the vehicle main body 2. In this way, the fender garnish 3 c is attached to a predetermined position of the vehicle body 2 via the attachment part 4 and the stopper 5.

  In the vehicle exterior component mounting device 1 described above, the locking piece 12 of the fender garnish 3c is inserted into the insertion hole 22 of the mounting component 4, and the locking is performed in a state where the mounting component 4 is superimposed on the fender garnish 3c. The heating portion 41a of the melting means 41 is pressed against the piece 12 and the rib 23 from the tip 12b side of the locking piece 12, and the locking piece 12 and the rib 23 are melted together, and the tip 12b side of the locking piece 12 is reached. It is possible to increase the size of the molten mass in which the locking portion 51 formed in the above, that is, the locking piece and the rib are melted together. Thereby, in the mounting apparatus 1 for exterior parts for vehicles, since the latching | locking part 51 is large, the latching piece 12 does not come out of the insertion hole 22, but the fitting part 4 is attached to the fender garnish 3c. Can be properly locked and integrated. Therefore, in the vehicle exterior component mounting device 1, it is assumed that the fender garnish 3c receives an impact from the outside, for example, vibration that occurs during traveling of the vehicle body 2 or a stone that a tire or the like jumps during traveling. In addition, the fender garnish 3c can be attached to the vehicle body 2 with high attachment strength via the attachment part 4 and the stopper 5 without the attachment part 4 being detached from the fender garnish 3c.

  In the mounting apparatus 1 for an exterior part for a vehicle, a stopper is not formed only by a locking piece as in the prior art, but the rib 23 of the mounting part 4 is melted together with the locking piece 12 so as to be melted together. Since the stop part 51 is formed and the locking part 51 can be enlarged, the thickness of the locking piece 12 can be reduced. Therefore, in the vehicle exterior component mounting device 1, the thickness of the locking piece 12 of the vehicle exterior component 4 can be reduced. Therefore, when the vehicle exterior component 4 is formed by an injection molding technique, the resin material flows in. There is no difference between the location where the locking piece 12 is disposed and other locations, and it is possible to prevent the occurrence of a sink mark at a position facing the locking piece 12 on the surface 11b of the vehicle exterior component 4.

  Moreover, in this vehicle exterior component mounting device 1, the locking piece 12 of the vehicle exterior component 4 is disposed along the bent portion 13 provided in the main body portion 11, for example, by injection molding technology. Even if the condition is wrong and a sink mark is generated at a position facing the locking piece 12 of the surface 11b, the generated sink mark can be made inconspicuous.

  In this vehicle exterior component mounting device 1, for example, even if a sink mark occurs when the mounting component 4 is formed by injection molding technology, the mounting component 4 is a mounting device that mounts the fender garnish 3 c to the vehicle body 2. Since it is not exposed, the thickness of the resin member forming the mounting portion 24 to which the stopper 5 is locked can be increased without considering the sink mark, and the stopper 5 can be firmly locked to the mounting portion 24. Can do.

  In this vehicle exterior part mounting device 1, the mounting part 4 is provided with a bulging portion 25, and when the fender garnish 3 c and the mounting part 4 are integrated, the latch inserted through the insertion hole 22. Since the vicinity of the base end 12a of the piece 12 is disposed in the space 25a between the fender garnish 3c of the bulging portion 25 and the mounting part 4, the melting of the locking piece 12 by the melting means 41 is stopped only at the tip 12b. Thus, melting to the vicinity of the base end 12a is prevented. Therefore, in the mounting apparatus 1 for a vehicle exterior part, it is possible to prevent the locking piece 12 from being melted to the vicinity of the base end 12a and the strength of supporting the fender garnish 3c of the locking piece 12 from being lowered.

  In the above description, the case where the fender garnish 3c is attached to the vehicle body 2 has been described as an example. However, the present invention is not limited to this. For example, a shock absorber or a scratch-proof device for a motorcycle, a train, an electric vehicle, or the like. It can also be applied when attaching functional car exterior parts. Further, in the above, the stopper 5 inserted through the locking hole 2a of the vehicle main body 2 and locked is used to attach the fender garnish 3c to the vehicle main body 2. However, the present invention is not limited to this. For example, a fender garnish 3c may be attached to the vehicle main body 2 using a bolt as the stopper 5 by arranging a so-called female screw in the attachment portion 24 of the attachment component 4 in which a spiral groove is provided on the inner surface. it can.
