[0033] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the stand column side beam connecting structure, the vehicle body assembly and the vehicle provided by the utility model will be further described in detail in combination with the drawings and the specific embodiment.

[0034] In the conventional technology, in order to improve the strength and rigidity of the pillar side beam and the vehicle body, the thickness of the side outer plate and the inner plate of the side beam is increased or a reinforcing plate is arranged between the side outer plate and the inner plate of the side beam. The increase of the thickness of the plate increases the weight of the vehicle body and increases the material cost. The embodiment of the utility model provides a pillar side beam connecting structure, which improves the strength and rigidity of the pillar side beam and the vehicle body and realizes lightweight of the material.

[0035] With reference to Figure 1 and Figure 2 The embodiment of the utility model provides a pillar side beam connecting structure, which comprises a side outer plate 1, a reinforcing pipe assembly 2 and an inner plate 3 of a side beam. An opening 11 is arranged on the side outer plate 1 and extends along the width direction of the vehicle. The reinforcing pipe assembly 2 is arranged between the side outer plate 1 and the inner plate 3 of the side beam. The reinforcing pipe assembly 2 is connected with the inner plate 3 of the side beam. The reinforcing pipe assembly 2 forms an avoiding space, which is communicated with the opening 11 and provides a moving space for a door hinge 4.

[0036] Specifically, as shown in Figure 1 and Figure 2 , wherein, Figure 2The connection structure between the reinforcing pipe assembly 2 and the inner panel of the side beam 3 and the installation position of the door hinge 4 are shown after the outer panel of the side wall 1 is hidden. The pillar side beam connection structure can be used to connect the vehicle pillars including the A-pillar, B-pillar or C-pillar. The vehicle A-pillar is taken as an example in the embodiment, that is, the pillar side beam connection structure is connected between the A-pillar and the door, and the pillar side beam connection structure includes the outer panel of the side wall 1, the reinforcing pipe assembly 2 and the inner panel of the side beam 3. The outer panel of the side wall 1 is located at the side of the vehicle body and constitutes the left and right side walls of the vehicle, and is usually formed by stamping a metal plate including steel or aluminum alloy. The inner panel of the side beam 3 is located at the inner side of the outer panel of the side wall 1 and faces the vehicle interior. It should be noted that the inner side in the embodiment of the utility model refers to the direction facing the vehicle interior, and the outer side refers to the direction facing the vehicle exterior. The outer panel of the side wall 1 is provided with an opening 11 along the width Y of the vehicle body to provide a moving space for the door hinge 4, that is, in the open state of the door, the door hinge 4 extends out of the outer panel of the side wall 1 through the opening 11, and one side of the door hinge 4 fixed to the door moves with the door; in the closed state of the door, the door hinge 4 is entirely accommodated and hidden in the opening 11. Therefore, the opening 11 of the outer panel of the side wall 1 provides a moving space for the door hinge 4 and can hide the door hinge 4 in the closed state of the door, which meets the aesthetic requirement. The door hinge 4 in the embodiment is a swing arm hinge and is suitable for a vehicle provided with a side sliding door. One side of the door hinge 4 is connected with the door, and the other side is connected with the related parts of the side beam of the vehicle through the opening 11 and moves to cooperate with the opening and closing process of the door. The shape and size of the opening 11 are determined according to the shape and size of the door hinge 4 to meet the moving space and accommodation requirement of the door hinge 4. It should be noted that the door hinge 4 does not directly contact the outer panel of the side wall 1, the reinforcing pipe assembly 2 and the inner panel of the side beam 3, and the opening 11 only provides a moving space for the door hinge 4.

[0037] Specifically, as Figure 2As shown, the reinforcing pipe assembly 2 is located in the cavity formed between the side outer plate 1 and the inner plate 3 of the side beam, and the reinforcing pipe assembly 2 is connected with the inner plate 3 of the side beam by welding or screwing. Part of the structure of the reinforcing pipe assembly 2 includes the first hot gas expansion pipe 21 and the second hot gas expansion pipe 22 attached to the inner side of the side outer plate 1. The reinforcing pipe assembly 2 plays a role of supporting and stabilizing the structure of the side outer plate 1 and the inner plate 3 of the side beam and improving the anti-collision ability. Due to the requirement of the activity space of the door hinge 4, the opening 11 is provided on the side outer plate 1, which affects the overall rigidity and strength of the side outer plate 1 and the column side beam to a certain extent. Therefore, the reinforcing pipe assembly 2 for improving the strength and rigidity is designed. The reinforcing pipe assembly 2 can be formed by a forming process combining forging, casting or heat treatment and gas expansion technology, and a pipe with high mechanical strength can be processed. The reinforcing pipe assembly 2 can be formed by a split connection of multiple reinforcing pipes or an integrated machining process. Compared with the conventional technology of reinforcing plate, the tubular structure of the reinforcing pipe assembly 2 has strong adaptability in shape and can be designed according to the specific shape of the side outer plate 1 and the inner plate 3 of the side beam. The reinforcing pipe assembly 2 is well fitted to the side outer plate 1 and the inner plate 3 of the side beam, and the connection gap is reduced. In addition, due to the hollow tubular structure, the reinforcing pipe assembly 2 has a lighter weight compared with the reinforcing plate design, and the lightweight vehicle body can be realized.

[0038] Specifically, as shown in the figure, Figure 2 The reinforcing pipe assembly 2 forms an avoiding space through the cooperation and connection of multiple reinforcing pipes. The avoiding space is in communication with the opening 11, that is, along the vehicle width Y. The projection of the avoiding space and the opening 11 at least partially overlaps, so that the avoiding space and the opening 11 can jointly provide the activity space of the door hinge 4. Exemplarily, the avoiding space can be formed between two reinforcing pipes arranged at intervals. The door hinge 4 can be arranged in the avoiding space, so that the door hinge 4 can be stretched out of the side outer plate 1 when the door is opened, and can be accommodated in the avoiding space through the opening 11 when the door is closed. The multiple reinforcing pipes are connected through cooperation, and the avoiding space is formed in the gap between the reinforcing pipes. Compared with the conventional technical idea of opening an opening in the reinforcing plate to form an avoiding space, the structural strength can be ensured not to be damaged.

[0039] The column side beam connecting structure provided by the embodiment of the utility model can realize the lightweight of the vehicle body part while ensuring the strength and rigidity of the column side beam, and the avoiding space formed by the reinforcing pipe assembly is in communication with the opening of the side outer plate, and the two jointly form the space required by the activity of the door hinge. In the state that the door is closed, the hinge can be hidden inside the side outer plate. The installation requirement of the door hinge is met, and the aesthetic requirement is met.

[0040] Optionally, referring to Figure 2The reinforcing pipe assembly 2 comprises at least two reinforcing pipes; at least one of the reinforcing pipes is connected with the inner plate of the side beam, and the end of at least one of the reinforcing pipes forms the avoiding space.

[0041] Specifically, the reinforcing pipe assembly 2 of the embodiment adopts at least two reinforcing pipe structures, that is, the number of reinforcing pipes is two, three or more. At least one of the reinforcing pipes is connected with the inner plate 3 of the side beam. When the number of reinforcing pipes is two, the two reinforcing pipes can be arranged in parallel or connected end to end, and the avoiding space is located at the end of one of the reinforcing pipes. When the number of reinforcing pipes is three, the three reinforcing pipes can be arranged in parallel, connected end to end or in a combined connection form. When the three reinforcing pipes are arranged in parallel or connected end to end, the avoiding space is located at the end of one of the reinforcing pipes. When the three reinforcing pipes are connected in a combined connection form, the end of one of the reinforcing pipes forms the avoiding space with the connection position of the other reinforcing pipes. Exemplarily, the three reinforcing pipes are connected in a combined connection form, in which the ends of two reinforcing pipes with small cross-sectional dimensions are connected with the end of another reinforcing pipe with a large cross-sectional dimension, the reinforcing pipe with the large cross-sectional dimension is connected with the inner plate 3 of the side beam, the avoiding space is located at the end of the reinforcing pipe with the large cross-sectional dimension and between the two reinforcing pipes with small cross-sectional dimensions. In comparison, if the reinforcing pipe assembly 2 adopts two reinforcing pipes arranged in parallel and extending to the front end of the column side beam, the total material cost of the reinforcing pipes can be reduced, but more connection points are needed due to the longer length of the two reinforcing pipes, which increases the complexity of the connection between the reinforcing pipes and the inner plate 3 of the side beam or the body sheet metal part, and the non-connection part of the reinforcing pipes and the sheet metal part needs an electrophoresis gap of about 5 mm, which reduces the effective cross-sectional area of the reinforcing pipes and the stiffness of the connection part of the reinforcing pipes. Therefore, the embodiment in which the three reinforcing pipes are connected in a combined connection form ensures the connection strength between the reinforcing pipes and the inner plate 3 of the side beam while reducing the connection points of the reinforcing pipes and improving the connection strength.

[0042] Optionally, referring to Figure 2 The reinforcing pipe assembly comprises a first hot gas expansion pipe 21, a second hot gas expansion pipe 22 and a third hot gas expansion pipe 23; the avoiding space is formed between the second hot gas expansion pipe 22 and the third hot gas expansion pipe 23, one end of the first hot gas expansion pipe 21 is connected with the same end of the second hot gas expansion pipe 22 and the third hot gas expansion pipe 23, and the one end of the first hot gas expansion pipe 21 is close to the avoiding space, and the other end of the first hot gas expansion pipe 21 is away from the second hot gas expansion pipe 22 and the third hot gas expansion pipe 23.

[0043] Specifically, the reinforcing pipe assembly 2 of the embodiment is composed of a plurality of hot gas expansion pipes. The hot gas expansion pipe is mainly obtained by heating a high-strength alloy pipe at high temperature and introducing a specific gas during the process, so that tiny pores are generated inside the pipe. The tiny pores expand at high temperature, so that the pipe is tightly connected with the side outer plate 1 or the inner plate 3 of the side beam after thermal expansion, thereby improving the strength and rigidity of the column side beam structure, improving the corrosion resistance, prolonging the service life, and reducing the weight of the parts. The reinforcing pipe assembly 2 of the embodiment includes a first hot gas expansion pipe 21, a second hot gas expansion pipe 22, and a third hot gas expansion pipe 23. The second hot gas expansion pipe 22 and the third hot gas expansion pipe 23 are arranged at intervals to form an avoiding space. The cross-sectional size of the second hot gas expansion pipe 22 and the third hot gas expansion pipe 23 is smaller, and the cross-sectional size of the first hot gas expansion pipe 21 is larger. One end of the first hot gas expansion pipe 21 is connected with the end of the second hot gas expansion pipe 22 and the end of the third hot gas expansion pipe 23 at the same time, and the one end of the first hot gas expansion pipe 21 is close to the avoiding space. The one end and the other end of the first hot gas expansion pipe 21 are the two ends of the extension direction. The other end of the first hot gas expansion pipe 21 is away from the second hot gas expansion pipe 22 and the third hot gas expansion pipe 23. The second hot gas expansion pipe 22 and the third hot gas expansion pipe 23 are located at the rear section of the side beam, and the other end of the first hot gas expansion pipe 21 is located at the front section of the side beam. Therefore, the embodiment adopts the form of connecting three hot gas expansion pipes, forms an avoiding space between the two hot gas expansion pipes arranged at intervals, and reduces the connection point of the hot gas expansion pipe, thereby improving the connection strength.

[0044] Optionally, referring to Figure 2 , the second hot gas expansion pipe 22 is attached to one side of the side outer plate 1 and fixed to the outer side surface of the first hot gas expansion pipe 21, and one end of the third hot gas expansion pipe 23 extends into one end of the first hot gas expansion pipe 21 and is fixedly connected with the first hot gas expansion pipe 21.

[0045] Specifically, as Figure 2 shown, in the embodiment, the front end of the first hot gas expansion pipe 21 extends to the front side of the column side beam, the first hot gas expansion pipe 21 is connected with the inner plate 3 of the side beam, and the connection mode can adopt welding or bolt connection, preferably bolt connection. The rear end of the first hot gas expansion pipe 21 extends to the rear side of the column side beam. The third hot gas expansion pipe 23 is fixedly connected with the first hot gas expansion pipe 21 by extending into the first hot gas expansion pipe 21 from one end of the first hot gas expansion pipe 21, and the connection between the third hot gas expansion pipe 23 and the first hot gas expansion pipe 21 can adopt welding or bolt connection, preferably welding. The second hot gas expansion pipe 22 is connected to the outer side surface of the first hot gas expansion pipe 21, and the connection between the second hot gas expansion pipe 22 and the first hot gas expansion pipe 21 adopts welding or bolt connection, preferably welding. The third hot gas expansion pipe 23 of the embodiment is fixedly connected with the first hot gas expansion pipe 21 by extending into the inside of the first hot gas expansion pipe 21, thereby improving the connection strength.

[0046] The embodiment designs a reinforcing structure of the hot gas expansion pipe, ensures the column side beam structure, reduces the weight of the vehicle body parts by about 20%, and realizes good lightweight effect.

[0047] Optionally, referring to Figure 4 , the column side beam connecting structure further comprises a threaded fastener 5; the threaded fastener 5 is fixed between the first hot gas expansion pipe 21 and the side beam inner plate 3, and the first hot gas expansion pipe 21 and the side beam inner plate 3 are fixedly connected.

[0048] Specifically, as shown in Figure 4 , the first hot gas expansion pipe 21 and the side beam inner plate 3 are fixed by bolt connection. The threaded fastener 5 is fixed between the first hot gas expansion pipe 21 and the side beam inner plate 3. Since the hot gas expansion pipe is a metal pipe and the side beam inner plate 3 is a sheet metal part, the bolt connection is adopted. In the conventional technology, the reinforcing plate and the side beam inner plate are connected by spot welding, which is prone to fatigue fracture due to residual stress and is not easy to disassemble. In addition, the bolt connection operation is simple and the process difficulty is low. In the embodiment, only four or fewer threaded fasteners 5 are needed to realize the connection and fixation of the first hot gas expansion pipe 21 and the side beam inner plate 3. The threaded fastener 5 can be a bolt, a screw or a pin.

[0049] Optionally, referring to Figure 3 , the second hot gas expansion pipe 22 is welded to the first hot gas expansion pipe 21.

[0050] Specifically, as shown in Figure 3 , the second hot gas expansion pipe 22 is located on the outer wall of the first hot gas expansion pipe 21, and is connected to the first hot gas expansion pipe 21 by welding, preferably by brazing. This process has good connection, the welding strength is close to the base material strength, only the welding equipment is simple and the cost is low, which is conducive to improving the production rhythm.

[0051] Optionally, referring to Figure 3 , a plurality of through holes 211 are formed in the side wall of the first hot gas expansion pipe 21 near the first end; the third hot gas expansion pipe 23 is welded to the first hot gas expansion pipe 21 through the through holes 211.

[0052] Specifically, as shown in Figure 3As shown, a plurality of through holes 211, i.e., caulking holes, are formed in the side wall of the first heat expansion tube 21. One end of the third heat expansion tube 23 is inserted into the first heat expansion tube 21 and connected by welding through the through holes 211. That is, the through holes 211 provide a space for the solder to combine with the base material after melting, ensuring the welding strength. The through holes 211 can be provided in multiple numbers, but on the basis of ensuring the welding strength, the number should be controlled not to be too large to avoid increasing the process complexity. Three through holes 211 distributed along the length direction of the first heat expansion tube 21 are provided in the embodiment.

[0053] Optionally, referring to Figure 4 , the number of the threaded fasteners 5 is multiple, and the multiple threaded fasteners 5 are arranged along the first heat expansion tube 21.

[0054] Specifically, as shown, Figure 4 the number of the threaded fasteners 5 is multiple, but on the basis of ensuring the connecting strength between the first heat expansion tube 21 and the inner plate 3 of the side beam, the number should be controlled not to be too large to avoid increasing the process complexity. Four threaded fasteners 5 arranged along the length direction of the first heat expansion tube 21 are provided in the embodiment.

[0055] The heat expansion tubes of the reinforcing tube assembly 2 of the embodiment are connected by welding, and the heat expansion tubes and the inner plate 3 of the side beam are connected by threading, so that the overall process is relatively simple. Compared with the mode that the reinforcing plate of the A-pillar upper side beam is connected to the upper side beam by thirty-nine welding points in the conventional technology, the number of the connection points is reduced, the process flow is optimized, and the production rhythm is improved.

[0056] The utility model embodiment further provides a vehicle body assembly, including the vertical column side beam connecting structure that any prior art embodiment has described.

[0057] The vehicle body assembly with the vertical column side beam connecting structure provided by the embodiment is composed of the reinforcing tube assembly of the heat expansion tube, the strength and rigidity of the vertical column side beam connecting structure and the vehicle body assembly are improved, and the lightweight demand is met.
