Description
Technical Field
The utility model relates to a vehicle stand structure.
Background
Conventionally, in a vehicle pillar structure provided between doors of a vehicle, a pillar having a hollow cross section is generally configured by using a pillar outer panel located on the outer side in the vehicle width direction and a pillar inner panel located on the inner side in the vehicle width direction, and the pillar is attached to a floor structure or a side cross member of a vehicle body. Wherein, the flange part formed by connecting the column outer plate and the column inner plate can be fixed by welding or bonding. For example, the column outer panel and the column inner panel are welded at the flange portion, and the joint rigidity between the column outer panel and the column inner panel is secured by filling the gap formed in the projection region other than the welded portion with an adhesive. However, the vehicle pillar structure is usually coated by electrodeposition (electro-deposition) or the like to enhance the rust prevention effect. When the flange portions of the outer and inner pillar panels are sealed by the welding portion and the adhesive, the coating liquid is difficult to flow into the hollow cross section of the pillar formed into the elongated cylindrical body, which results in poor coating effect, and further affects the rust prevention effect of the vehicle pillar structure, and makes it difficult to suppress the deterioration rate of the vehicle pillar structure.

The edges of the pillar outer panel 110 and the pillar inner panel 120 are connected to each other to form a flange portion F, and the welding portion 130 and the bonding portion 140 are disposed on the flange portion F. As shown in fig. 2 to 4, a plurality of welding portions 130 are distributed on the flange portion F to weld the pillar outer panel 110 and the pillar inner panel 120 along the entire periphery of the flange portion F. Preferably, the bonding portion 140 may be provided in a plurality (but not limited thereto), and the bonding portion 140 and the welding portion 130 are staggered (as shown in fig. 3), so as to enhance the connection rigidity between the pillar outer panel 110 and the pillar inner panel 120. However, the present invention does not limit the number and arrangement of the welding portions 130 and the bonding portions 140, and does not limit whether other fixing means are provided, which can be adjusted according to the requirement.
Furthermore, in the present embodiment, the bonding portion 140 is provided with an adhesive 142 for bonding the pillar outer panel 110 and the pillar inner panel 120, and the bonding portion 140 is provided with a through hole 144 communicating with the hollow section C of the pillar P. In detail, as shown in fig. 4, the portions of the flange portions F of the pillar outer panel 110 and the pillar inner panel 120 corresponding to the welding portions 130 are closely attached to each other without any gap, the portions of the flange portions F corresponding to the welding portions 130 (i.e., the bonding portions 140) are formed in a protruding structure by the pillar inner panel 120, and the adhesive 142 is disposed in the recessed space formed by the protruding structure, thereby improving the connection rigidity between the pillar outer panel 110 and the pillar inner panel 120. However, in other embodiments, which are not shown, the protruding structures may be provided on the flange portions F of the pillar outer panel 110, or the protruding structures may be provided on both the pillar outer panel 110 and the pillar inner panel 120 to fill the adhesive 142. Further, the flange portions F of the pillar outer panel 110 and the pillar inner panel 120 corresponding to the bonding portions 140 are not completely filled with the adhesive 142, but are formed with a slight gap to form a through hole 144 communicating with the hollow cross section C of the pillar P.
As described above, in the vehicle pillar structure 100 according to the present invention, the pillar outer panel 110 and the pillar inner panel 120 form the pillar P having the hollow cross section C, the plurality of welding portions 130 weld the pillar outer panel 110 and the pillar inner panel 120 to each other on the flange portion F, the bonding portion 140 has the adhesive 142 on the flange portion F between the welding portions 130 to bond the pillar outer panel 110 and the pillar inner panel 120, and the bonding portion 140 has the through hole 144 communicating with the hollow cross section C of the pillar P. In this way, the pillar outer panel 110 and the pillar inner panel 120 are rigidly connected by welding the welded portion 130 and bonding the adhesive 142 on the bonding portion 140, and when coating is performed by electrodeposition or the like, a coating liquid (not shown) can be supplied from the through-hole 144 into the hollow cross section C of the pillar P (for example, the inflow path a shown in fig. 3), thereby enhancing the coating effect of the vehicle pillar structure 100 to enhance the rust prevention effect, and further suppressing the deterioration rate of the vehicle pillar structure 100. Accordingly, the vehicle pillar structure 100 can suppress the deterioration rate by securing the rust prevention effect while securing the connection rigidity of the pillar outer panel 110 and the pillar inner panel 120.
In addition, in the present embodiment, as shown in fig. 2 to 4, the vehicle pillar structure 100 further includes a reinforcement 150 that is provided in the hollow cross section C of the pillar P and is located between the pillar outer panel 110 and the pillar inner panel 120, thereby reinforcing the pillar outer panel 110 and the pillar inner panel 120. The reinforcement 150 is, for example, a cover member configured in a long strip shape, and the flange portion F is configured by connecting the edge of the reinforcement 150 and the edges of the pillar outer panel 110 and the pillar inner panel 120. That is, in the case where the reinforcement 150 is provided, the flange portion F includes the outer pillar panel 110, the inner pillar panel 120, and the edge of the reinforcement 150, but is not limited thereto. The reinforcement 150 is sandwiched between the pillar outer panel 110 and the pillar inner panel 120 at the flange portion F, and is welded to the pillar outer panel 110 and the pillar inner panel 120 at the weld portion 130 (as shown in fig. 2 and 4). Accordingly, the adhesive 142 of the bonding portion 140 is disposed in the recessed space formed by the protruding structure of the pillar inner panel 120 and between the pillar inner panel 120 and the reinforcement 150, but in other embodiments not shown, the adhesive 142 may be disposed between the pillar outer panel 110 and the reinforcement 150, or the adhesive 142 may be disposed between the pillar inner panel 120 and the reinforcement 150 and between the pillar outer panel 110 and the reinforcement 150.
Furthermore, in the present embodiment, as shown in fig. 2 to 4, a through hole 144 communicating with the hollow cross section C of the pillar P is further provided in a portion of the flange portion F corresponding to the bonding portion 140, and the through hole 144 of the bonding portion 140 also corresponds to the reinforcement 150. As such, in the present embodiment, the reinforcement 150 achieves connection rigidity through welding of the welding portion 130 and adhesion of the adhesive 142 on the adhesion portion 140, and when painting is performed through electrodeposition or the like, a painting liquid (not shown) can be supplied from the through hole 144 into the hollow section C of the column P (for example, an inflow path a shown in fig. 3). In particular, when the reinforcement 150 is provided, since the reinforcement 150 is sandwiched between the pillar outer panel 110 and the pillar inner panel 120 at the flange portion F and the through-hole 144 of the adhesion portion 140 is located between the pillar outer panel 110 and the reinforcement 150 (as shown in fig. 4), the reinforcement 150 can be effectively coated with the coating liquid flowing into the hollow cross section C of the pillar P through the through-hole 144, whereby the coating effect of the vehicle pillar structure 100 is enhanced to enhance the rust prevention effect, and the deterioration rate of the vehicle pillar structure 100 is suppressed.
In addition, in the present embodiment, as shown in fig. 2 to 4, the bonding portion 140 is disposed on the flange portion F and between two adjacent ones of the welding portions 130, and the through hole 144 of the bonding portion 140 is disposed between the adhesive 142 and the welding portion 130. That is, it is preferable that the adhesive 142 is disposed at a central region of the bonding portion 140, and the through holes 144 are disposed at both side regions of the bonding portion 140, whereby the through holes 144 are located at opposite sides of the adhesive 142, and the through holes 144 are located between the adhesive 142 and the adjacent welding portions 130. In this way, the through holes 144 can be formed at appropriate intervals to more reliably supply the coating liquid into the hollow cross section C of the pillar P. However, the arrangement of the adhesive 142 and the through holes 144 is not limited to the above, and the bonding portions 140 are not limited to each having the adhesive 142 and the through holes 144, which can be adjusted according to the requirement.
In addition, in the present embodiment, as shown in fig. 2, it is preferable that the adhesive 142 of the bonding portion 140 extends from the flange portion F into the hollow section C of the pillar P. That is, the adhesive 142 extends from the outer edge of the flange portion F to the inner edge of the flange portion F, and crosses over the inner edge of the flange portion F to enter a portion of the pillar inner panel 120 that is located inward of the flange portion F. However, the present invention is not limited to the adhesive 142 extending from the outer edge of the flange portion F to the inner edge of the flange portion F, and may extend from the middle of the flange portion F to the inner edge of the flange portion F. Thus, the through hole 144 formed by the side of the adhesive 142 can be regarded as extending from the bonding portion 140 into the hollow section C of the pillar P. In this way, the coating liquid can more reliably flow into the hollow cross section C of the column P through the through-hole 144. However, the present invention does not limit the setting range of the adhesive 142, and it can be adjusted according to the requirement.
To sum up, the utility model discloses an among the vehicle stand structure, stand planking and stand inner panel constitute the stand that has the hollow cross section, and a plurality of welding parts weld stand planking and stand inner panel on flange portion, and the portion of adhereing is equipped with the binder on flange portion and between the welding part in order to adhere stand planking and stand inner panel, and is equipped with the through-hole of the hollow cross section of intercommunication stand in the portion of adhereing. Preferably, the reinforcing member is sandwiched between the pillar outer panel and the pillar inner panel at the flange portion, and is welded to the pillar outer panel and the pillar inner panel at the welding portion, so that the through-hole of the adhesion portion also corresponds to the reinforcing member. Thus, the outer column plate and the inner column plate are welded through the welding part and bonded through the adhesive on the bonding part to realize connection rigidity, and coating liquid can flow into the hollow section of the column through the through hole when coating is carried out through means such as electro-deposition, so that the coating effect of the vehicle column structure is improved to enhance the anti-rust effect, and the deterioration speed of the vehicle column structure is further inhibited. According to this, the utility model discloses a vehicle stand structure can ensure the rigidity of being connected of stand planking and stand inner panel, ensures antirust effect simultaneously and restraines the degradation speed.
