Description

  The present invention relates to a vehicle floor spacer comprising a lower limb impact absorbing pad and a horizontal pad, and more particularly to a vehicle floor spacer that can increase the manufacturing efficiency of the floor spacer and has a very high finished shape accuracy. Is.

  In general, on the indoor floor of a vehicle, in order to protect the lower limbs of the occupant from impacts such as when a vehicle collides, the lower limb shock absorbing pad installed on the occupant's feet in front of the floor and on the floor behind it A vehicle floor spacer composed of a horizontal pad is installed.

  Conventional vehicle floor spacers are manufactured by a method in which a lower limb impact absorbing pad and a horizontal pad are formed separately, and both are bonded or fitted together. For example, the automobile floor spacer disclosed in Patent Document 1 is a prime example. This floor spacer is made of hard plastic and is composed of a shock absorber made by molding the surface on the vehicle body side when installing the vehicle into a honeycomb structure or a slit structure, and a floor spacer (horizontal pad) made of the same material, A floor spacer for an automobile is formed by fitting a projection provided on the shock absorbing material into a through-hole formed in the floor spacer.

JP 2003-118460 A

  According to the automobile floor spacer disclosed in Patent Document 1, the automobile floor spacer is formed by a simple method of fitting the convex portion provided on the shock absorbing material into the through hole formed in the floor spacer (horizontal pad). can do. However, in such a manufacturing method by fitting two members together or a manufacturing method by bonding as described above, the angle of the shock absorbing material (lower limb shock absorbing pad) slightly deviates from the normal angle with respect to the horizontal pad. Such a slight shift has caused a problem that the floor spacer does not conform to the shape of the interior of the vehicle where the floor spacer is to be installed. Further, in order to avoid such a slight shift, there is a great deal of dependence on the skill of a skilled assembly worker. Therefore, in mass production of floor spacers, a reduction in work efficiency has been a problem.

  The vehicle floor spacer of the present invention has been made in view of the above-mentioned problems, and while improving the manufacturing efficiency of the floor spacer composed of the lower limb impact absorbing pad and the horizontal pad, the finished shape accuracy of the floor spacer is also extremely high. An object of the present invention is to provide a high vehicle floor spacer.

  In order to achieve the above object, a vehicle floor spacer according to the present invention includes a horizontal pad that has a horizontal upper surface that is indoors when installed in a vehicle, and a plurality of bottom surfaces that are on the vehicle body side when installed in a vehicle. A floor spacer for a vehicle comprising a lower limb shock absorbing pad formed with a concave groove, wherein the lower limb shock absorbing pad and the horizontal pad are integrally formed of foamed resin particles, and the lower limb shock absorbing member is formed. At least a side surface on the vehicle rear side of the concave groove formed in the pad is formed to be perpendicular or substantially perpendicular to the upper surface of the horizontal pad.

  The horizontal pad is provided to adjust the bulkiness of the floor surface and to ensure flatness in a horizontal plane. Therefore, the upper surface which is the indoor side at the time of installation is generally formed horizontally. On the other hand, the lower limb shock absorbing pad is provided to prevent the damage to the lower limbs by absorbing the impact at the time of vehicle collision, in addition to the adjustment of the bulkiness of the foot floor and the flatness in the inclined surface. It is.

  A plurality of concave grooves are formed on the bottom surface on the vehicle body side when the lower limb impact absorbing pad is installed on the vehicle. Here, the shape of the groove is not particularly limited, and for example, a vertically long shape extending in the front-rear direction and the left-right direction of the vehicle, a rectangular shape, a circular shape, an elliptical shape, etc. are applicable. . Also, the groove depth can be adjusted as appropriate, and if the shape (including the depth) can absorb shock energy effectively by buckling the concave groove at the time of a vehicle collision, it should be set appropriately. Can do.

  In addition, the foamable resin particles for molding the horizontal pad and the lower limb impact absorbing pad are not particularly limited. However, when thermoplastic resin particles are used as the foamable resin particles, styrene-modified polyethylene resin, polystyrene Resin, polyethylene resin, polypropylene resin, and the like can be used. When a thermosetting resin is used as the foamable resin, a polyurethane resin or the like can be used. Among them, styrene-modified polyethylene resin resin particle foam molded products obtained by impregnating and polymerizing polyethylene resin particles with styrene monomers include polyethylene resin particle foam molded products and polypropylene resin particle foam molded products. Compared to the above, it is particularly preferable because it is excellent in dimensional stability and shape retention and is less likely to generate powder due to rubbing than a foamed molded product of polystyrene resin particles. The proportion of the styrene component in the styrene-modified polyethylene resin is 40 to 90% by weight, preferably 50 to 85% by weight, more preferably 55 to 75% by weight.

  When molding the floor spacer, for example, a thermoplastic resin such as the above-mentioned styrene-modified polyethylene resin is impregnated with a foaming agent to form a foamable thermoplastic resin, and the foamable thermoplastic resin is heated with steam or the like. Pre-foamed particles are produced by pre-foaming. Then, the pre-expanded particles are filled in a mold and foam-molded. Here, the expansion ratio of the floor spacer is preferably formed by pre-expanded particles adjusted within a range of 5 to 70 times, for example. Since the thing with a foaming ratio of less than 5 becomes very hard, sufficient plastic deformation performance by a foam cannot be expected. On the other hand, if the expansion ratio exceeds 70 times, the foam is too soft and it is difficult to obtain a reaction force as the foam.

  The vehicle floor spacer according to the present invention solves the problem of the conventional manufacturing method in which the lower limb impact absorbing pad and the horizontal pad are integrally molded in one molding die, and then both are molded separately and then joined. Is. Here, the lower limb shock absorbing pad is generally extended at an arbitrary angle corresponding to the shape of the vehicle body with respect to the horizontal pad (the horizontal upper surface thereof). In such an aspect, when forming the above-mentioned concave groove on the bottom surface of the lower limb shock absorbing pad, if the floor spacer is removed after molding the floor spacer in the mold, the concave groove interferes with the mold. There is a possibility that it cannot be removed. Specifically, in a mold composed of a fixed mold and a movable mold, after the floor spacer is molded in the mold, the floor spacer attached to the movable mold is removed from the fixed mold by opening the movable mold and movable. The floor spacer is removed by removing the floor spacer from the mold. When opening the movable mold, the concave groove provided on the bottom surface of the floor spacer interferes with the concave groove forming protrusion (or protrusion) provided in the cavity of the fixed mold, and the movable mold is opened. Is inhibited.

  Therefore, at least the side surface on the vehicle rear side among the side surfaces defining the concave groove is formed perpendicularly or substantially perpendicular to the upper surface of the horizontal pad (the projection for forming the fixed groove is vertical or substantially vertical). Therefore, it is possible to prevent the concave groove and the fixed mold from interfering with each other. Note that at least the side surface on the rear side of the vehicle means that not only the side surface on the rear side of the vehicle but also the side surface on the front side of the vehicle and further the side surface extending in the front-rear direction of the vehicle can be formed vertically or substantially vertically.

  As described above, the vehicle floor spacer according to the present invention can be manufactured in a simple manner because the floor spacer composed of the lower limb impact absorbing pad and the horizontal pad can be integrally manufactured from a single mold. Furthermore, since it is not necessary to connect both the molded leg impact absorbing pad and the horizontal pad, it is possible to obtain a floor spacer having a desired shape, that is, a floor spacer having high shape accuracy.

  Further, another embodiment of the vehicle floor spacer according to the present invention includes a horizontal pad in which an upper surface that is indoors when installed in a vehicle is horizontally formed, and a plurality of bottom surfaces that are on the vehicle body side when installed in a vehicle. A floor spacer for a vehicle comprising a lower limb shock absorbing pad formed with a concave groove, wherein the lower limb shock absorbing pad and the horizontal pad are integrally formed of foamed resin particles, and the lower limb shock absorbing member is formed. Of the concave grooves formed in the pad, the side surface on the vehicle rear side is formed so as to be a surface opened to the vehicle rear side with respect to the perpendicular to the upper surface of the horizontal pad, and the side surface on the vehicle front side is the horizontal pad It is formed so that it may become a surface opened ahead of the vehicle rather than the perpendicular to the upper surface.

  The vehicle floor spacer according to the present invention is formed so that the side surface on the vehicle rear side of the concave groove formed in the lower limb shock absorbing pad is a surface opened to the vehicle rear side from the perpendicular to the upper surface of the horizontal pad. The side surface on the front side of the vehicle is formed so as to be a surface that opens to the front side of the vehicle with respect to the vertical to the upper surface of the horizontal pad, thereby preventing interference between the mold and the groove when the mold is opened.

  In the present embodiment, the side surface of the groove extending in the front-rear direction of the vehicle may be perpendicular or substantially perpendicular to the upper surface of the horizontal pad, or from the bottom surface toward the groove bottom of the groove. An inclined aspect may be used. In other words, the cross-sectional shape of the concave groove is formed so as to expand from the bottom surface of the lower limb impact absorbing pad, thereby preventing interference between the molding die and the concave groove during demolding.

  According to the vehicle floor spacer of the present invention, it is possible not only to prevent interference between the mold and the concave groove when the mold is opened, but also to remove the mold more easily.

  Another embodiment of the vehicle floor spacer according to the present invention includes a lower limb impact absorbing pad having a plurality of protrusions formed on a bottom surface on the vehicle body side when installed in a vehicle, and a rear side of the lower limb impact absorbing pad. A floor pad for a vehicle comprising: a horizontal pad provided to ensure flatness in at least a horizontal plane, wherein an upper surface which is indoors when installed on a vehicle is formed horizontally and at least flatness in a horizontal plane is secured. The lower limb shock absorbing pad and the horizontal pad are integrally formed of foamable resin particles, and at least the front side surface of the protrusion formed on the lower limb shock absorbing pad is on the upper surface of the horizontal pad. It is characterized in that it is formed perpendicularly or substantially perpendicularly.

  The vehicle floor spacer of the present invention is a lower limb impact absorbing pad having a flat bottom surface, for example, which has a protrusion of an arbitrary shape on the bottom surface, and effectively absorbs impact energy by providing a cross-sectional defect portion. In the point which can be performed, it is the same as that of the aspect which provided the ditch | groove mentioned above.

  The shape of the protrusion is arbitrary, and may be, for example, a vertically long form extending in the front-rear direction of the vehicle, or a form in which protrusions having a circular, elliptical, or polygonal cross section are scattered.

  Also in the vehicle floor spacer according to the present invention, at least the side surface of the protrusion on the front side of the vehicle is placed on the horizontal pad so that the protrusion having an arbitrary shape does not interfere with, for example, the fixed mold of the mold when being removed from the mold. It is formed perpendicular to or substantially perpendicular to the upper surface. Here, the side surface of the protrusion on the rear side of the vehicle and the side surface extending in the front-rear direction of the vehicle can be formed perpendicularly or substantially perpendicular to the upper surface of the horizontal pad as described above.

  Another embodiment of the vehicle floor spacer according to the present invention includes a lower limb impact absorbing pad having a plurality of protrusions formed on a bottom surface on the vehicle body side when installed in a vehicle, and a rear side of the lower limb impact absorbing pad. A floor pad for a vehicle comprising: a horizontal pad provided to ensure flatness in at least a horizontal plane, wherein an upper surface which is indoors when installed on a vehicle is formed horizontally and at least flatness in a horizontal plane is secured. The lower limb shock absorbing pad and the horizontal pad are integrally formed of foamable resin particles, and among the protrusions formed on the lower limb shock absorbing pad, the side surface on the vehicle rear side is the upper surface of the horizontal pad. The side surface on the front side of the vehicle is formed to be a surface opened on the rear side of the vehicle with respect to the vertical line to the upper surface of the horizontal pad. Made is characterized in that is.

  The vehicle floor spacer of the present invention is formed such that, of the protrusions formed on the lower limb impact absorbing pad, the side surface on the vehicle rear side is a surface opened to the vehicle front side from the perpendicular to the upper surface of the horizontal pad. The side surface on the front side of the vehicle is formed so as to be a surface opened to the rear side of the vehicle with respect to the vertical line to the upper surface of the horizontal pad, thereby preventing interference between the molding die and the protrusion when the mold is opened as described above. It is.

  The side surface of the protrusion that extends in the vehicle front-rear direction may be a flat surface or a curved surface that is inclined so that the cross-sectional shape of the protrusion extends from the distal end portion of the protrusion toward the bottom surface of the lower limb shock absorbing pad.

  According to the vehicle floor spacer of the present invention, it is possible not only to prevent interference between the mold and the concave groove when the mold is opened, but also to remove the mold more easily.

  Another embodiment of the vehicle floor spacer according to the present invention is characterized in that in the vehicle floor spacer, the shock absorbing pad and the horizontal pad are formed of different raw materials.

  Here, the different types of raw materials are the same material of pre-expanded particles having different expansion ratios, the raw materials of the different pre-expanded particles themselves, and further, the materials of the pre-expanded particles and the respective Means raw materials having different foaming ratios.

  For example, any one of the above-described styrene-modified polyethylene resin, polystyrene resin, polyethylene resin, polypropylene resin, etc. is selected and the lower limb impact absorbing pad and the horizontal pad are integrally molded. Here, the pre-foamed particles for horizontal pads and the pre-foamed particles for impact absorbing pads for the lower limbs, which have different foaming ratios, are filled in one mold and foam-molded. At this time, it is preferable to partition the inside of the mold cavity with a partition member, and simultaneously fill the left and right spaces of the partition member with the respective pre-expanded particles, and remove the partition member from the cavity after filling.

  Since the impact absorbing performance is required for the lower limb shock absorbing pad, the lower limb shock absorbing pad is made as low as possible by lowering the expansion ratio of the pre-foamed particles (higher density) than the horizontal pad. The floor spacer can be molded in a manner that is lightweight and has the desired shock absorption performance, and the horizontal pad can be molded as lightly as possible, while ensuring the shock absorption performance required for the lower limb shock absorption pad. The overall weight can be made as light as possible.

  As can be understood from the above description, according to the vehicle floor spacer of the present invention, the lower limb shock absorbing pad and the horizontal pad, each having a concave groove or protrusion on the bottom surface, are integrally molded with a single mold. Therefore, it is possible to increase the manufacturing efficiency and to obtain a vehicle floor spacer with extremely high finished shape accuracy. Further, according to the vehicle floor spacer of the present invention, the lower limb shock absorbing pad and the horizontal pad can be integrally formed from different materials, so that the shock absorbing performance required for the lower limb shock absorbing pad is ensured. However, it is possible to obtain a vehicle floor spacer whose overall weight is as light as possible.

It is formed in such a manner.

  Next, a method for manufacturing the floor spacer 10 will be described with reference to FIGS.

  The floor spacer 10 is integrally formed in a single mold in such a manner that the raw material is different between the lower limb impact absorbing pad 1 and the horizontal pad 2. Here, a general mold can be used as the mold, and it is composed of a fixed mold 5 positioned below and a movable mold 6 positioned above, as shown in FIG. A cavity corresponding to the shape of the floor spacer is formed on the surface.

  In the present embodiment, for example, a styrene-modified polyethylene resin is used, and the pre-expanded particles for the lower limb impact absorbing pad are pre-expanded at a lower magnification than the pre-expanded particles of the horizontal pad. The cavity is filled from the filling ports 61 and 62. Here, in the vicinity of the boundary between the lower limb shock absorbing pad and the horizontal pad in the cavity, a partition member 7 is provided in advance so that both particles do not mix, and each shape is separated from the inner wall surface of the cavity. It is defined by the member 7. In the fixed mold 5, a ridge 51 for forming a concave groove is provided on the cavity surface that forms the lower limb shock absorbing pad 1.

  FIG. 11 shows a situation in which the respective pre-expanded particles 81 and 82 are filled in the cavity. However, both the pre-expanded particles 81 and 82 are filled at the same time, and after the filling, the partition member 7 is inserted from the inside of the cavity. Removed promptly. The partition member 7 may be removed by, for example, providing an appropriate partition member 7 removing means in the direction perpendicular to the drawing sheet.

  FIG. 12 shows a state where the floor spacer 10 is attached to the cavity surface of the movable mold 6 by moving the movable mold 6 in the mold opening direction after the pre-foamed particles 81 and 82 are foam-molded in the cavity. The situation where the floor spacer 10 is removed from the fixed mold 5 is shown.

  Here, the vehicle rear side surface 31 of the groove 3 provided on the bottom surface of the lower limb shock absorbing pad 1 is perpendicular to the horizontal upper surface of the horizontal pad 2, and the vehicle front side surface 32 of the groove 3 is Since it is formed on the surface opened to the front side of the vehicle with respect to the vertical line with respect to the upper surface of the horizontal pad 2, the mold of the movable mold 6 can be smoothly formed without interfering with the grooves 3 and the protrusions 51 at the time of mold removal. An opening is made. As described above, the side surface of the groove 3 extending in the vehicle front-rear direction is perpendicular to the top surface of the horizontal pad 2 or has a shape in which the cross-sectional shape is divergent from the bottom surface toward the top end surface of the groove. Is formed.

  Needless to say, the lower limb impact absorbing pad and the horizontal pad may be made of the same raw material. In this case, the cavity need not be partitioned by a partition member. Of course, the configuration of the mold may be other than the illustrated configuration.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
