Description

  The present invention relates to a vehicle body side part structure that constitutes a side wall of a vehicle body and that has a front panel and a side panel that is supported on a running surface by front and rear wheels.

  Conventionally, there is a vehicle body side structure of the vehicle described in Patent Document 1 below. According to this publication, a sheet metal side panel is provided which constitutes the side wall of the vehicle body, and whose front and rear end portions are supported on the running surface by the front and rear wheels. The side panel includes a side outer panel that forms a side surface outside the vehicle body, and a side inner panel that is coupled to the side outer panel and forms a side surface inside the vehicle body. Before communicating, the rear door opening is formed. In particular, as shown in FIG. 11A, the side outer panel is integrally formed by pressing, but conventionally, the side inner panel is integrally formed in the same manner as this. There is a case.

  Here, the side wall of the vehicle body has doors for closing the front and rear door openings so that they can be opened and closed. Normally, a pivoting tool that pivotally supports the door on the side outer panel or side inner panel and a locking tool that releasably locks the door to the panels can be attached to a part of the panels as vehicle parts. It is said. In addition, a reinforcing material for reinforcing the mounting portion such as the above-mentioned locking tool can be attached to a part of each panel as a vehicle body part.

  And since the above-mentioned conventional side outer panel and side inner panel are each integrally formed by press processing, firstly, the forming operation of each of these panels can be easily performed. The side panel can be easily formed, which is preferable in terms of vehicle body productivity.

  Second, since the side outer panel and the side inner panel each have structural continuity in the surface direction, the rigidity of each part in the surface direction is smoothly changed to prevent rapid changes. That is, the occurrence of a rigid break point where stress concentration is likely to occur is prevented. For this reason, when an impact force is applied to the vehicle body from the traveling surface via the front and rear wheels during traveling of the vehicle, it is prevented that stress concentration occurs at the rigid break point and the side panel is easily deformed. Is preferable in terms of maneuverability and ride comfort.

JP 2001-334957 A

  Incidentally, as described above, the side panel is supported at both ends by the front and rear wheels with respect to the traveling surface of the vehicle. For this reason, when an impact force is applied to the side panel from the traveling surface via the front and rear wheels during traveling of the vehicle, the portions sandwiched between the front and rear door openings of the side outer panel and the side inner panel by the impact force, respectively. A large bending moment tends to be given to the middle part of the longitudinal direction including each panel of the center pillar.

  As a result, when the side outer panel and the side inner panel are integrally formed, particularly, there is no attachment of the vehicle body parts as compared with a part of each panel where the vehicle body parts are attached, thereby improving rigidity. In other parts of the panels that cannot be prevented, the impact force may cause a large elastic deformation in the width direction of the vehicle body, which is the thickness direction. As described above, when the other part of each panel is largely bent and deformed, the side panel tends to be deformed such as torsion, which may reduce the operability and riding comfort of the vehicle. Arise.

  Therefore, in particular, it is conceivable to increase the width dimension and cross-sectional area of each longitudinal portion of each panel of the center pillar to improve its rigidity and prevent bending deformation of each panel of the center pillar. However, if this is simply done, the front and rear door openings will be narrowed due to the panels of the center pillar having a larger width dimension and cross-sectional area, and boarding / alighting of the interior of the vehicle body through these door openings will be hindered. This is not preferable because it may cause

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

According to the first aspect of the present invention, there is provided a side panel that constitutes the side wall of the vehicle body, the front and rear end portions thereof are supported on the traveling surface by the front and rear wheels, and the outside of the vehicle body of the side panel is provided with the side surface. In the vehicle body side structure in which the front and rear door openings are formed on the side outer panel to be formed and the side outer panel is integrally formed, and a vehicle body part can be attached to a part of the side outer panel.

An upper end of the reinforcing panel is joined to the upper opening edge of the front and rear door openings in the middle of the side outer panel, and a lower end of the reinforcing panel is joined to the front of the middle of the side outer panel. The side outer panel joined to the lower opening edge of the rear door opening has no reinforcing material other than the vehicle body part that can be the reinforcing panel and the reinforcing material.

  For this reason, since the side outer panel is integrally formed as described above, the side outer panel can be easily formed. Therefore, the side panel having the side outer panel as a constituent element can be easily formed.

  On the other hand, the side outer panel includes a center pillar outer panel which is a portion sandwiched between the front and rear door openings of the side outer panel when an impact force is applied to the side panel through the front and rear wheels when the vehicle is traveling. A large external force tends to be applied to the middle part of the front-rear direction. Moreover, in the middle part of the side outer panel, there is no mounting of the vehicle body parts as described above, and the rigidity is improved by this as compared with a part of the side outer panel which can be expected to improve the rigidity especially by mounting the vehicle body parts. In other parts of the side outer panel that cannot be bent, there is a risk that it will be bent and deformed elastically in the width direction of the vehicle body, which is the thickness direction.

  However, since the reinforcing panel joined to the middle part in the front-rear direction of the side outer panel is provided to reinforce the other part of the side outer panel as described above, the other part in the middle part of the side outer panel is the reinforcing panel. Thus, improvement in rigidity is achieved, and therefore, it is more reliably prevented that the middle part of the side outer panel is easily bent and deformed by the impact force.

It is more reliably prevented that the inside of the vehicle body is greatly deformed. This is extremely useful for protecting the passengers inside the vehicle body corresponding to the front and rear door openings of the side outer panel.

  Further, as described above, since the rigidity of the middle part of the side outer panel is increased by the reinforcing panel joined to the side outer panel, the rigidity of the middle part of the side outer panel is particularly improved in the longitudinal direction of the center pillar outer panel. This can be achieved while suppressing an increase in the width dimension and cross-sectional area of the substrate. Therefore, even when the rigidity of the middle part of the side outer panel is improved as described above, the front and rear door openings are prevented from being narrowed due to the center pillar outer panel, and the interior of the vehicle body through these door openings is prevented. You can get on and off smoothly.

  The various effects can be achieved by integrally forming the side outer panel and joining a reinforcing panel only to a midway portion of the side outer panel. Therefore, the reinforcing panel can be made smaller and lighter than the conventional technology in which a reinforcing material is provided for each part of the side outer panel. It can be made lighter and its productivity can be improved.

The invention according to claim 2 constitutes a side wall of the vehicle body, the front and rear end portions thereof are provided with side panels supported on the traveling surface by the front and rear wheels, and the interior of the side panel of the vehicle body has the side surface. In the vehicle body side structure, the front and rear door openings are formed on the side inner panel to be formed and the side inner panel is integrally formed, and a vehicle body part can be attached to a part of the side inner panel.
In order to reinforce the other part of the side inner panel, it is joined only to the middle part of the side inner panel in the front-rear direction including the part sandwiched between the front and rear door openings. A reinforcing panel is provided , and an upper end portion of the reinforcing panel is joined to upper opening edge portions of the front and rear door openings in the middle portion of the side inner panel, and a lower end portion of the reinforcing panel is connected to the side inner panel. It is joined to the lower opening edge of the front and rear door openings in the middle part, and the side inner panel has no reinforcing material other than the vehicle body parts that can be the reinforcing panel and the reinforcing material.

  For this reason, in description of the said effect by the said Claim 1, the effect which replaced the side outer panel with the side inner panel and the center pillar outer panel with the center pillar inner panel respectively arises.

According to a third aspect of the present invention, there is provided a side panel that constitutes the side wall of the vehicle body, the front and rear end portions thereof are supported on the running surface by the front and rear wheels, and the side panels face each other in the width direction of the vehicle body. And a side outer panel and a side inner panel that are coupled to each other. Before these two panels communicate with each other, a rear door opening is formed, and both the panels are individually formed integrally. In the vehicle body side part structure in which vehicle body parts can be attached to a part,
In order to reinforce the other parts of the two panels, of the respective parts of both the panels, the respective parts including the parts sandwiched by the front and rear door openings are straddled only in the respective middle parts in the front-rear direction. Reinforcing panels to be joined to each other are provided , and the upper end of the reinforcing panel is joined to the upper opening edge of the front and rear door openings in the middle part of the side panel, and the lower end of the reinforcing panel is It is joined to the lower opening edge of the front and rear door openings in the middle part of the side panel, and both the panels do not have any reinforcing material other than the vehicle body parts that can be the reinforcing panel and the reinforcing material .

  For this reason, said each effect by the said Claim 1 and Claim 2 arises.

  Moreover, since the said reinforcement panel is shared by the said side outer and a side inner panel, the said each effect is achieved by simpler part.

  The vehicle body 2 of the vehicle 1 is made of a sheet metal that constitutes a lower part of the vehicle body 2 and a vehicle body frame 3 that constitutes a skeleton member of the vehicle body 2, and is supported on the vehicle body frame 3. Body body 5 and a pair of left and right front and rear wheels 6 and 7 supported by a suspension device (not shown) at the front and rear of the body frame 3, respectively. Thus, the vehicle body 2 is supported on the traveling surface 8.

  The vehicle body 5 constitutes left and right side walls, and front and rear end portions of the vehicle body 5 are supported on the traveling surface 8 by the front and rear wheels 6 and 7, and the left and right side panels 11 A roof panel 12 is provided on each upper edge and forms the upper surface of the passenger compartment 4.

  The side panel 11 includes a side outer panel 15 in which the outside of the vehicle body 2 of the side panel 11 forms a side surface, and a side inner panel 16 in which the inside of the body 2 of the side panel 11 forms a side surface. Yes. The side outer panel 15 and the side inner panel 16 face each other in the width direction of the vehicle body 2, and the side outer and side inner panels 15 and 16 are formed with rear door openings 19 and 20 before they communicate with each other. The The side outer and side inner panels 15 and 16 are individually formed by pressing integrally from a single metal plate. In the side outer and side inner panels 15 and 16, portions sandwiched between the front and rear door openings 19 and 20 are a center pillar outer panel 22 and a center pillar inner panel 23, respectively. A center pillar 24 is formed by the center pillar outer and center pillar inner panels 22 and 23.

  The outer edge portions in the surface direction of the side outer and side inner panels 15 and 16 and the opening edge portions of the front and rear door openings 19 and 20 are connected to each other by spot welding S1, and each portion of the side panel 11 is A hollow closed cross-section structure is used to improve rigidity. In addition, at least a part of each of the front and rear end portions of the side outer and side inner panels 15 and 16 is positioned above the front and rear wheels 6 and 7 in a side view of the vehicle body 2 (FIG. 1).

  The cross section of each part in the longitudinal direction of the center pillar outer panel 22 and the center pillar inner panel 23 has a hat shape that is convex toward the outside of the vehicle body 2. In this case, the hat shape of the center pillar outer panel 22 is known, but by making the center pillar inner panel 23 the hat shape, its section modulus is increased, and therefore, the center pillar inner panel 23. At the same time, the rigidity of the center pillar 24 is improved. Specifically, the center pillar outer panel 22 is integrally formed with the front and rear panels 22a and 22b facing each other in the front-rear direction of the vehicle body 2 and the outer edge portions of the front and rear panels 22a and 22b. A side panel 22c to be coupled and an outward flange 22d integrally formed on each inner edge of the front and rear panels 22a and 22b are provided. The center pillar inner panel 23 includes a front panel 23a, a rear panel 23b, a side panel 23c, and an outward flange 23d so as to have the same configuration as the center pillar outer panel 22. The outward flanges 22d and 23d of the center pillar outer panel 22 and the center pillar inner panel 23 are joined to each other by spot welding S1.

  The side wall of the vehicle body 2 has a door 27 that closes the front and rear door openings 19 and 20 so as to be opened and closed. Further, as the vehicle body part 28, a pivotal support that pivotally supports the door 27 to the side outer panel 15 and the side inner panel 16 and a locking tool that releasably locks the door 27 to the panels 15 and 16 are used. The panels 15 and 16 can be attached to the portions 15a and 16a. In addition, a reinforcing material for reinforcing the attachment portion such as the above-described locking tool can be attached to the portions 15 a and 16 a of the panels 15 and 16 as the vehicle body part 28.

  The side outer panel 15 includes a center pillar outer panel 22 which is a portion sandwiched between the front and rear door openings 19 and 20 among the portions of the side outer panel 15 so as to reinforce the other portion 15b of the side outer panel 15. A reinforcing panel 32 that is joined only to the midway portion 31 in the front-rear direction is provided. Specifically, the reinforcing panel 32 is formed on the inner surface of the side panel 22c of the center pillar outer panel 22 across the portion 15a and the other portion 15b of the side outer panel 15 in the middle portion 31 of the side outer panel 15. Joined by spot welding S2. The upper end of the reinforcing panel 32 is also joined to the inner surfaces of the upper opening edge portions of the front and rear door openings 19 and 20 in the middle portion 31 of the side outer panel 15.

  The reinforcing panel 32 may be joined only to the other portion 15 b of the side outer panel 15 in the middle portion 31 of the side outer panel 15. Further, the lower end portion of the reinforcing panel 32 may be joined to the inner surfaces of the lower opening edge portions of the front and rear door openings 19 and 20 in the middle portion 31 of the side outer panel 15. In addition to spot (point) welding, the joining may be by various resistance welding or arc welding, or by a fastener using various bolts.

  The side outer panel 15 and the side inner panel 16 are high tension or ultra high strength steel plates. On the other hand, the reinforcing panel 32 is thicker than the side outer panel 15 and the side inner panel 16 and has a greater strength.

  According to the above configuration, the rigidity of the center pillar outer panel 22 and the center pillar inner panel 23 is increased by increasing the section modulus. For this reason, when the vehicle 1 travels, the impact force applied to the side panel 11 from the traveling surface 8 via the front and rear wheels 6 and 7 and the external force F applied to the side panel 11 from the outside of the vehicle body 2 are as follows. The side outer panel 15 and the side inner panel 16 are firmly supported by the middle portions 31 of the side outer panel 15 and the side inner panel 16, respectively.

  Further, as described above, the side outer panel 15 includes a portion sandwiched between the front and rear door openings 19 and 20 among the respective portions of the side outer panel 15 so as to reinforce the other portion 15b of the side outer panel 15. A reinforcing panel 32 that is joined only to the midway portion 31 in the front-rear direction is provided.

  Here, as described above, since the side outer panel 15 and the side inner panel 16 are integrally formed, the side outer panel 15 and the side inner panel 16 can be easily formed. The side panel 11 having 16 as a component can be easily formed.

  On the other hand, when an impact force is applied from the traveling surface 8 to the side panel 11 of the vehicle body 2 via the front and rear wheels 6 and 7 during traveling of the vehicle 1, as described in detail in the prior art, the side outer panel 15 Before this, a large external force tends to be applied to the middle portion 31 in the front-rear direction of the side outer panel 15 including the center pillar outer panel 22 that is sandwiched between the rear door openings 19 and 20. In addition, in the middle portion 31 of the side outer panel 15, there is no attachment of the vehicle body part 28 as described above, in particular, compared with the part 15a of the side outer panel 15 in which improvement in rigidity can be expected due to the attachment of the vehicle body part 28. The other portion 15b of the side outer panel 15 in which the rigidity cannot be improved as a result, there is a risk that it will be greatly bent and deformed elastically in the width direction of the vehicle body 2 that is the thickness direction.

  Moreover, at least a part of each of the front and rear end portions of the side panel 11 is disposed above the front and rear wheels 6 and 7 in a side view of the vehicle body 2 (FIG. 1). For this reason, the length of the side panel 11 in the front-rear direction of the vehicle body 2 tends to be long as the side panel 11 is formed to straddle the front and rear wheels 6 and 7. As a result, the middle portions 31 of the side outer panel 15 and the side inner panel 16 of the side panel 11 may be more elastically bent and deformed in the thickness direction due to the impact force when the vehicle 1 travels. Occurs.

  However, since the reinforcing panel 32 joined to the middle part 31 in the front-rear direction of the side outer panel 15 is provided so as to reinforce the other part 15b of the side outer panel 15 as described above, in the middle part 31 of the side outer panel 15 described above. The rigidity of the other portion 15b is improved by the reinforcing panel 32. Therefore, the middle portion 31 of the side outer panel 15 is more reliably prevented from being bent and deformed easily by the impact force. Therefore, deformation such as torsion or the like in the side panel 11 due to the impact force during traveling of the vehicle 1 is more reliably prevented, and as a result, the operability and riding comfort of the vehicle 1 are maintained well.

  Further, when an object collides (side impact) with the side surface of the vehicle body 2, the impact force, which is the external force F, is caused by the midway portion 31 of the side outer panel 15 whose rigidity is increased by the reinforcing panel 32 as described above. The midway portion 31 is firmly supported, and the inside of the vehicle body 2 can be prevented from being greatly deformed. This is extremely useful for protecting passengers inside the vehicle body 2 corresponding to the front and rear front and rear door openings 27 and 28 in front of the side outer panel 15 and the side inner panel 16.

  Further, as described above, since the rigidity of the middle part 31 of the side outer panel 15 is increased by the reinforcing panel 32 joined thereto, the rigidity of the middle part 31 of the side outer panel 15 is improved particularly in the center pillar. This can be achieved while suppressing an increase in the width dimension and cross-sectional area of each part in the longitudinal direction of the outer panel 22. Therefore, even when the rigidity of the middle portion 31 of the side outer panel 15 is improved as described above, the front and rear door openings 27 and 28 are prevented from being narrowed by the center pillar outer panel 22, and the door openings 27 , 28 can smoothly get on and off the inside of the vehicle body 2.

  The various effects can be achieved by integrally forming the side outer panel 15 and the side inner panel 16 and joining the reinforcing panel 32 only to the middle portion 31 of the side outer panel 15. Therefore, the reinforcing panel 32 can be made smaller and lighter than the conventional conventional technique in which reinforcing members are provided in the respective parts of the side outer panel 15 and the side inner panel 16. The configuration can be made simpler and lighter, and the productivity can be improved.

  The side outer panel 15 and the side inner panel 16 may be made of a metal material such as an aluminum alloy, a carbon fiber (carbon) material, or a resin-made resin that is injection-molded or reinforced with fibers. .
