Based on the structure, the side collision safety performance and the noise and vibration resistance performance of the vehicle can be improved without increasing the manufacturing cost of the vehicle.
Description
Technical Field
The utility model relates to a vehicle lateral part structure.
Background
In general, side members having a closed cross-sectional structure extending in the vehicle length direction are provided on both sides of a vehicle interior floor in the vehicle width direction. In order to improve the side collision safety performance and the noise and vibration resistance performance of a vehicle, a plurality of partitions that partition a side sill in the vehicle length direction are often provided inside the side sill.
In such a structure in which the partition is provided inside the side sill having a closed cross-section structure, the side sill inner panel, the side sill outer panel, and the partition constituting the side sill are often joined together by bolts or by an adhesive.
However, in the case of the bolt connection, there is a problem that the number of members increases, which increases the cost. In addition, in the case of the bolt connection, in consideration of a dimensional error between the side sill and the partition plate, it is necessary to form the bolt hole as a large escape hole, and the large escape hole causes a decrease in strength, so that there is a problem that a high strength cannot be obtained even if the partition plate is provided. In addition, rainwater and the like may infiltrate into the inside of the side sill from a large escape hole.
On the other hand, when the adhesive is used for bonding, there is a problem that the cost is increased because of the need for equipment investment for coating and the like. In addition, there is a problem that the electrodeposition paint is hardly adhered to the coated surface of the adhesive.
SUMMERY OF THE UTILITY MODEL
To the technical problem, an object of the utility model is to provide a vehicle lateral part structure that is provided with boundary beam of closed cross-section structure that neither can make the cost rise can improve side impact security performance and anti-noise and anti vibration performance again.
As a technical solution to solve the above technical problem, the present invention provides a vehicle side structure including a side member disposed at both ends of a vehicle width direction of a vehicle compartment floor and extending in a vehicle length direction, characterized in that: the roof side rail is a tubular member having a closed cross-sectional structure including a roof side rail outer panel located on the outer side in the vehicle width direction and a roof side rail inner panel located on the inner side in the vehicle width direction with respect to the roof side rail outer panel, and a partition panel provided inside the roof side rail is joined to both the roof side rail inner panel and the roof side rail outer panel by welding, and the partition panel is in contact with the inner surface of the roof side rail inner panel and the inner surface of the roof side rail outer panel.
Based on the utility model discloses an above-mentioned vehicle lateral part structure, because the baffle is welded on the boundary beam, so compare with the structure that adopts between baffle and the boundary beam through bolted connection or through the adhesive bonding, can reduce the cost. Further, since it is not necessary to form a large escape hole as in the case of the bolt-fastened structure, the strength of the side sill does not decrease, and rainwater or the like does not infiltrate into the inside of the side sill. Further, since the partition plate is welded to both the inner and outer side frames, the collapse of the side frame section due to the deformation of the inner and outer side frames can be suppressed, and the torsional rigidity of the side frame can be increased, thereby improving the side collision safety of the vehicle, and since the deformation of the side frame section in the vehicle height direction can be suppressed, the road noise can be greatly reduced, and the noise and vibration resistance can be improved.
In addition, in the above-described vehicle side portion structure of the present invention, preferably, the partition plate is joined to one of the side sill inner panel and the side sill outer panel by spot welding, and is joined to the other of the side sill inner panel and the side sill outer panel by laser spiral welding.
Conventionally, in the case of spot welding which requires only sandwiching members to be joined from both sides by electrodes, it has been difficult to weld a spacer to both of an inner panel and an outer panel of a side sill having a closed cross-sectional structure. However, according to the present invention, after the separator is welded to one of the side sill plates by spot welding, the separator can be welded to the other side sill plate by laser screw welding from the outside of the side sill having a closed cross-section structure formed by the side sill inner panel and the side sill outer panel. Thus, the side sill having a closed cross-sectional structure in which the bulkhead is welded to both the inner and outer side sill plates can be easily realized.

Detailed Description
Hereinafter, a vehicle side portion structure of the present embodiment will be described with reference to the drawings.
Fig. 1 is a schematic cross-sectional view showing a vehicle side portion structure of the present embodiment. As shown in fig. 1, this vehicle side portion structure includes a floor panel 50 that constitutes a floor of a vehicle interior 40, a floor cross member 51 that reinforces the floor panel 50, side members 1 provided at both ends of the floor panel 50 in the vehicle width direction, and a partition panel 30 that partitions the side members 1 in the vehicle length direction.
The floor cross member 51 is a framework member extending in the vehicle width direction, and includes a floor upper cross member 53 provided on the upper side of the floor 50, and a floor lower cross member 55 provided on the lower side of the floor 50. The floor upper cross member 53 is configured to protrude upward, has a substantially hat-shaped cross section, and has a pair of front and rear flange portions (not shown) joined to the upper surface of the floor 50 to form a closed cross section together with the floor 50. On the other hand, the floor lower cross member 55 is formed in a substantially hat shape having a downwardly convex cross section, and a pair of front and rear flange portions (not shown) thereof are joined to the lower surface of the floor panel 50 to form a closed cross section together with the floor panel 50.
The side sill 1 includes a side sill outer panel 20 positioned on the outer side in the vehicle width direction, and a side sill inner panel 10 positioned on the inner side in the vehicle width direction with respect to the side sill outer panel 20.
The rocker inner panel 10 has an upper flange portion 11, an upper wall portion 12 extending inward in the vehicle width direction from a lower end portion of the upper flange portion 11, an inner wall portion 13 extending downward from an inner end portion of the upper wall portion 12 in the vehicle width direction, a lower wall portion 14 extending outward in the vehicle width direction from a lower end portion of the inner wall portion 13, and a lower flange portion 15 extending downward from an outer end portion of the lower wall portion 14 in the vehicle width direction. That is, the rocker inner panel 10 is configured to protrude inward in the vehicle width direction and to have a cross section that approximates a hat shape.
The side sill outer 20 includes an upper flange portion 21, an upper wall portion 22 extending outward in the vehicle width direction from a lower end portion of the upper flange portion 21, an upper outer wall portion 23 extending downward from an outer end portion of the upper wall portion 22 in the vehicle width direction, a ridge portion 24 extending downward from a lower end portion of the upper outer wall portion 23 obliquely inward in the vehicle width direction and extending downward further obliquely outward in the vehicle width direction, a lower outer wall portion 25 extending downward from a lower end portion of the ridge portion 24, a lower wall portion 26 extending inward in the vehicle width direction from a lower end portion of the lower outer wall portion 25, and a lower flange portion 27 extending downward from an inner end portion of the lower wall portion 26 in the vehicle width direction. That is, the side sill outer 20 is formed to protrude outward in the vehicle width direction and to have a cross section that is approximately hat-shaped.
The upper flange 11 of the inner rocker 10 and the upper flange 21 of the outer rocker 20 are joined by spot welding, and the lower flange 15 of the inner rocker 10 and the lower flange 27 of the outer rocker 20 are joined by spot welding, thereby forming the rocker 1 having a closed cross-sectional structure.
The vehicle width direction end of the floor upper cross member 53 is joined to the outer surface of the upper wall portion 12 of the rocker inner panel 10 by welding or the like, and the vehicle width direction end of each of the floor 50 and the floor lower cross member 55 is joined to the outer surface of the lower wall portion 14 of the rocker inner panel 10 by welding or the like, so that the rocker 1 is provided to extend in the vehicle length direction at both vehicle width direction end portions of the floor of the vehicle interior 40.
On the other hand, a resin-made rocker garnish 57 that covers the upper outer wall portion 23, the ridge portion 24, the lower outer wall portion 25, the lower wall portion 26, and the lower flange portion 27 of the rocker outer panel 20 is provided on the outer side in the vehicle width direction of the rocker 1. Further, a side outer panel 59 that covers the upper wall portion 22 and the upper flange portion 21 of the rocker outer panel 20 is provided on the outer side of the rocker 1 in the vehicle width direction. In this way, since the side outer panel 59 and the side sill garnish 57 cover the outside of the side sill outer panel 20 of the side sill 1 in the vehicle width direction, even when the front door 7 including the door inner panel 8 and the door outer panel 9 is in an open state, the side sill outer panel 20 of the side sill 1, which is a framework member, is not exposed to the outside and the appearance effect is not impaired.
Fig. 2 is a schematic diagram showing the arrangement position of the bulkhead 30 in the vehicle side portion structure. In order to improve the side collision safety performance and the noise and vibration resistance performance (hereinafter, also referred to as NV performance) of the vehicle, a partition plate 30 is provided inside the side member 1 having a closed cross-sectional structure as shown in fig. 1. Specifically, as shown in fig. 2, in the side member 1 extending in the vehicle length direction, one or more of the partition plates 30 are disposed at four positions in total, two positions (a portion and B portion) corresponding to the front door opening 41 between the front pillar 3 and the center pillar 5, one position (C portion) corresponding to the center pillar 5, and one position (D portion) corresponding to the rear door opening 43 behind the center pillar 5. Fig. 1 is a sectional view taken along the line I-I in fig. 2 and showing the direction of arrows.
In general, when the bulkhead 30 is provided inside the side sill 1 having the closed cross-sectional structure, the side sill inner panel 10 and the side sill outer panel 20 constituting the side sill 1 are often joined to the flange portions 31 and 33 of the bulkhead 30 by bolts or adhesives, and there is a problem that the cost is increased by the bolts or adhesives.
In contrast, it is conceivable to join the flange portions 31 and 33 of the bulkhead 30 to the side sill 1 by spot welding, but if only spot welding is employed, which requires sandwiching of electrodes between both sides of the members to be joined, it is difficult to weld the bulkhead 30 to both sides of the side sill inner panel 10 and the side sill outer panel 20 of the side sill 1 having the closed cross-sectional structure.
In contrast, it is also conceivable to join the rocker inner panel 10 and the rocker outer panel 20 to form a closed cross section after only the inner flange portion 31 of the bulkhead 30 is joined to the rocker inner panel 10 by spot welding. However, if only the inner flange portion 31 of the bulkhead 30 is joined to the rocker inner panel 10, as shown in fig. 3, when the rocker 1 is subjected to a torsional force indicated by a black solid arrow, the rocker outer panel 20 may be deformed as indicated by a reference character 80, and the cross section of the rocker 1 may collapse. In order to suppress the collapse of the cross section of the side sill 1, the thickness of the side sill outer 20 needs to be increased, which causes a problem that it is difficult to reduce the size and weight.
In view of the above, in the present embodiment, the bulkhead 30 provided inside the rocker 1 is joined to both the rocker inner panel 10 and the rocker outer panel 20 by welding, and the bulkhead 30 is in contact with the inner surface of the rocker inner panel 10 and the inner surface of the rocker outer panel 20, respectively. Specifically, after the flange portion 31 of the bulkhead 30 is joined to the rocker inner panel 10 by spot Welding, the flange portion 33 of the bulkhead 30 is joined to the rocker outer panel 20 by Laser Screw Welding (LSW), whereby the flange portion 31 of the bulkhead 30 is brought into contact with the inner surface of the rocker inner panel 10 and the flange portion 33 of the bulkhead 30 is brought into contact with the inner surface of the rocker outer panel 20.
The above-described laser spiral welding method is different from a general laser welding method in that a plurality of metal members (for example, metal plates) overlapped together are melted by laser light, and then the plurality of metal members are joined together by stirring a molten pool formed by the melted metal by scanning a laser beam. Here, "scanning" means changing the irradiation position while irradiating with a laser beam.
Specifically, as shown in fig. 1, the bulkhead 30 has inner surfaces engageable with the upper wall portion 12, the inner wall portion 13, and the lower wall portion 14 of the rocker inner panel 10; and the outer shape in which the upper outer wall portion 23, the ridge portion 24, and the inner surface of the lower outer wall portion 25 of the rocker outer panel 20 are in contact with each other. An inner flange portion 31 and an outer flange portion 33 extending in the vehicle length direction are formed on the outer peripheral portion of the bulkhead 30; the partition 30 has small protrusions 35, 36, and 37 formed in its main body to increase its rigidity.
When the separator 30 having the above-described structure is installed inside the side sill 1, first, a voltage is applied (pressurized) between the inner flange 31 of the separator 30 and the inner wall 13 of the side sill inner panel 10 with electrodes (not shown), and current is caused to flow between the electrodes in a pressurized state three times to form three weld spots 61, 62, and 63, so that the inner flange 31 of the separator 30 can be joined to the inner surface of the inner wall 13 of the side sill inner panel 10 by spot welding.
Next, in a state where the partition 30 is joined to the inner surface of the rocker inner panel 10 by spot welding, the upper flange portion 11 of the rocker inner panel 10 is joined to the upper flange portion 21 of the rocker outer panel 20 by spot welding, and the lower flange portion 15 of the rocker inner panel 10 is joined to the lower flange portion 27 of the rocker outer panel 20 by spot welding, thereby forming the rocker 1 having a closed cross-sectional structure. In the thus-configured rocker 1 having the closed cross-sectional structure, the outer flange portion 33 of the bulkhead 30 is in contact with or close to the upper outer wall portion 23, the ridge portion 24, and the lower outer wall portion 25 of the rocker outer panel 20.
Then, the outer flange portion 33 of the bulkhead 30 can be joined to the inner surface of the side sill outer panel 20 by laser screw welding by irradiating the laser beam from the outside of the side sill outer panel 20 four times to form four total welding spots (the welding spot 71 and the welding spot 72 on the upper side outer wall portion 23, the welding spot 73 on the ridge portion 24, and the welding spot 74 on the lower side outer wall portion 25).
Next, the results of simulation experiments regarding the side collision safety performance and the NV performance of the vehicle side portion structure of the present embodiment will be described with reference to fig. 4 and 5. Fig. 4 is a schematic view showing a state of the side sill 1 in the vehicle side portion structure of the present embodiment at the time of a side collision, and fig. 5 is a schematic view showing a state of the side sill 101 in the vehicle side portion structure of the related art at the time of a side collision. Here, in the side sill 101 of the vehicle side structure of the related art, the flange portion of the bulkhead 130 is joined to the side sill inner panel 110 only by spot welding.
As shown in fig. 5, in the side portion structure of the vehicle of the related art, the side sill outer 120 is denatured to cause the collapse of the cross section of the side sill 101, and particularly, the deformation of the side sill 101 in the vehicle height direction is large.
In contrast, as shown in fig. 4, in the vehicle side portion structure of the present embodiment, since the deformation amount of the side sill outer 20 is small, the cross-sectional collapse of the side sill 1 is suppressed, and it is verified that the amount of protrusion of the center pillar 5 into the vehicle interior 40 at the time of a side collision is effectively controlled by improving the torsional rigidity of the side sill 1.
In addition, in the vehicle side portion structure of the present embodiment, deformation of the side member 1 in the vehicle height direction can be suppressed without increasing the plate thickness of the side member outer panel 20, and the amplitude of the resonance frequency in the road noise frequency range can be greatly reduced. Thus, the effect of reducing the size of the side sill 1 and facilitating the weight reduction is demonstrated.
In the present embodiment, the flange portion 31 of the bulkhead 30 is joined to the rocker inner panel 10 by spot welding, and the flange portion 33 of the bulkhead 30 is joined to the rocker outer panel 20 by laser screw welding. However, the present invention is not limited to this, and on the contrary, the flange portion 33 of the spacer 30 may be joined to the outer sill panel 20 by spot welding, and the flange portion 31 of the spacer 30 may be joined to the inner sill panel 10 by laser screw welding.
