Description

  The present invention relates to a body structure for an automobile in which the body (vehicle body) of an automobile is molded and processed with a transparent acrylic resin material, has a light weight and high rigidity, and has a good visibility when the surroundings of the automobile are viewed from the interior of the vehicle.

  For passenger cars such as sedans, coupes, wagons, vehicles such as one-boxes (commercial vehicles), trucks, and small buses, a chassis frame having a skeleton structure is provided on the suspension device, and the chassis frame is made of a thin plate. An automobile body is formed. In this automobile body, a steel plate is press-molded by a die for each part. Thereafter, the automobile body is attached to the chassis frame by welding or the like.

  The automobile body formed by combining many panel parts as described above has a large body weight because the body is formed of a steel plate. Therefore, damage to passengers in the event of a collision accident is large.

Thus, for example, Japanese Patent Application Laid-Open No. 6-219323 (Patent Document 1) is known as a technique for reducing the weight of the vehicle body and suppressing damage at the time of collision. In the technique described in Patent Document 1, a vehicle body and members are formed of reinforced plastic in which glass fibers are mixed with ABS resin obtained by polymerizing three types of monomers of acrylonitrile, butadiene, and styrene on a body outer plate. . This reduces the weight of the vehicle body and reduces damage during an accident.
JP-A-6-219323

  However, in the thing of the said patent document 1, since the body which forms a vehicle body outer plate is the structure only formed with the reinforced plastic which mixed the glass fiber in ABS resin, the field of view from the vehicle interior to the outside is Unfortunately, it is difficult to ensure safe driving, and because glass is mixed in ABS resin, there is a problem that the body material cannot be reused after the automobile is scrapped.

  The present invention has been devised to solve such problems. The body of the automobile is integrally molded with a light-transmitting acrylic resin material while reducing the weight of the automobile body. Accordingly, an object of the present invention is to achieve a safe driving by improving the field of view from the passenger compartment to the outside of the vehicle and to obtain an automobile body structure that can be easily recycled.

  In order to solve the above-mentioned problems, the following measures are taken in the present invention. That is, the first invention is a vehicle body structure in which an automobile body is mounted on a chassis frame having a suspension device. The automobile body has portions other than openings such as a front window glass, a side door, and a rear door. It is integrally formed using a transparent acrylic resin material.

  The second invention is characterized in that the automobile body is colored using a coloring member.

  According to the first device, the entire body excluding openings such as the front window glass, the side door, and the rear door is integrally formed using a transparent acrylic resin material, and the integrally formed body is a suspension. It is attached to the chassis frame equipped with the device. For this reason, a vehicle in which the rigidity of the automobile body is enhanced as a whole can be obtained by the chassis frame and the automobile body mounted on the chassis frame. In addition, the transparency of the acrylic resin material improves the field of view from the vehicle interior to the outside of the vehicle body, so that safe driving can be effectively realized. In addition, since the acrylic resin material itself is a material that can be easily reused, an automobile body structure that is environmentally friendly and suitable for resource recycling can be realized.

  In addition, according to the second device, since the automobile body is colored using the coloring member, the automobile body structure excellent in appearance design can be obtained by coloring the car body according to the preference of the user who owns the automobile. Can be obtained.

Embodiment 1
Hereinafter, a case where the body structure of the vehicle according to Embodiment 1 of the present invention is applied to a coupe type passenger car will be described as an example with reference to FIGS. 1 and 2. FIG. 1 is an external perspective view of an automobile body (hereinafter referred to as “body”) 10 viewed obliquely from the front, and FIG. 2 is an external perspective view of the body 10 incorporated in a chassis frame 20.

  The chassis frame 20 of the coupe type passenger car is formed into a skeleton structure obtained by appropriately combining box-shaped or U-shaped steel materials. An engine room frame 21 for mounting an engine (not shown) and a vehicle room frame 22 for mounting a seat (not shown) and forming a vehicle interior space are formed in front of the structure.

  Further, a floor panel (not shown) is provided on the passenger compartment frame 22 by welding or the like. Thus, the chassis frame 20 as the vehicle body basic structure is formed.

  Further, a front wheel 23 and a rear wheel 24 are provided at a lower portion of the chassis frame 20 formed as described above via a suspension device (not shown). Of course, although not shown, a driving force transmission device such as a transmission and a propeller shaft for transmitting the driving force of the engine to the wheels 23 and 24 is provided in addition to the suspension device.

  On the other hand, the body 10 attached to the upper part of the chassis frame 20 is integrally formed as a whole by, for example, injection molding using a colorless and transparent acrylic resin material, as shown in FIG. When molding by this injection molding, the front window glass mounting opening 11, the side door mounting opening 12, the rear door mounting opening 13, the side window glass mounting opening 14, and the engine bonnet mounting opening 15 are excluded. All the remaining parts are integrally molded.

  The acrylic resin material used for the body 10 has extremely high transparency such that the absorption loss of transmitted light is about 1/20 that of glass, and is durable even if exposed to sunlight and rain for a long time. It has weather resistance. In addition, it has excellent environmental pollution resistance that generates almost no toxic gas even when burned.

  Furthermore, it has a light and tough impact resistance of about 10 times that of glass, is easy to cut, and has excellent workability such as bonding, bending, and drilling, and excellent chemical resistance. It has the characteristics of For this reason, the acrylic resin material is a very good material for constituting the body 10 of the automobile.

  As shown by the two-dot chain line in FIG. 2, the body 10 is suspended from the upper side in the assembly line and set on the chassis frame 20. When the setting position is determined, the vehicle body 10 is fixed to the chassis frame 20 using appropriate fastening means such as bolts, screws, nuts, and adhesives.

  The process after the automobile body 10 is fixed to the chassis frame 20 is performed as follows. That is, the front window glass is attached to the front window glass attachment opening 11. A side door made of acrylic resin (not shown) is attached to each side door attachment opening 12 on the left and right using a hinge member (not shown).
