[0041] In the related art, the body pillars include A-pillars, B-pillars, C-pillars and D-pillars. During the side collision of a car, the structural strength of the body pillars plays a very important role. After a side collision of a car, the body pillars will invade the passenger compartment. The amount of invasion is determined by the strength of the body pillars. The higher the strength, the smaller the invasion. With the continuous tightening of collision regulations and the increasing popularity of frameless doors, the requirements for body pillars in side collisions are also getting higher and higher. The current collision regulations require that the body pillars have a good intrusion amount and intrusion method after a collision. In order to achieve a good intrusion amount, the existing body pillars include an outer plate, a reinforcement plate, an inner reinforcement plate and an inner plate from the outside to the inside, and a high-strength body pillar structure is formed by welding. However, the body pillar reinforcement plate in the related art is not designed with local reinforcement parts, so that the local body pillar cannot effectively avoid or reduce a large intrusion amount, and cannot effectively deal with side collisions.
[0042] In order to solve the above problems, the present application provides a vehicle body pillar and a vehicle, including: a reinforcement, an inner panel and a structural insert; the reinforcement is connected to the inner panel, the reinforcement includes a first end close to the top of the vehicle and a second end close to the bottom of the vehicle, and the cross-sectional area of the reinforcement close to the first end is smaller than the cross-sectional area close to the second end; the structural insert is arranged between the reinforcement and the inner panel and connected to the reinforcement, and the structural insert is located on the side of the reinforcement close to the first end. By arranging the structural insert as a local reinforcement on the reinforcement plate, the local part of the vehicle body pillar can effectively avoid or reduce a large intrusion amount, and can effectively deal with side collisions.
[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.
[0044] The vehicle body pillars include an A-pillar, a B-pillar, a C-pillar and a D-pillar, wherein the B-pillar is a pillar between the front door area and the rear door area of the motor vehicle. When the B-pillar is used as an example for description, the reinforcement 100 is a B-pillar reinforcement 100, the upper reinforcement 101 is a B-pillar upper reinforcement 101, the lower reinforcement 102 is a B-pillar lower reinforcement 102, the reinforcement welding line 103 is a B-pillar reinforcement welding line 103, the inner panel 500 is a B-pillar inner panel 500, the upper inner panel 501 is a B-pillar upper inner panel 501, the lower inner panel 502 is a B-pillar lower inner panel 502, and the inner panel welding line 503 is a B-pillar inner panel welding line 503. The B-pillar is used as an example for description below.
[0045] First, please refer to Figure 1-Figure 2The embodiment of the present application provides a vehicle body pillar, including: a B-pillar reinforcement 100, a B-pillar inner panel 500 and a structural insert 400; the B-pillar reinforcement 100 is connected to the B-pillar inner panel 500, the B-pillar reinforcement 100 includes a first end close to the top of the vehicle and a second end close to the bottom of the vehicle, and the cross-sectional area of the B-pillar reinforcement 100 close to the first end is smaller than the cross-sectional area close to the second end; the structural insert 400 is arranged between the B-pillar reinforcement 100 and the B-pillar inner panel 500, and is connected to the B-pillar reinforcement 100, and the structural insert 400 is located on a side of the B-pillar reinforcement 100 close to the first end.
[0046] The B-pillar of the vehicle is composed of a B-pillar reinforcement 100 and a B-pillar inner plate 500 from outside to inside. The first end of the B-pillar reinforcement 100 is close to the top of the vehicle, and the second end of the B-pillar reinforcement 100 is close to the bottom of the vehicle. The cross-sectional area of the B-pillar reinforcement 100 near the first end is smaller than the cross-sectional area near the second end. The cavity of the B-pillar reinforcement 100 gradually decreases from bottom to top and eventually decreases to zero. The interval between the B-pillar reinforcement 100 and the B-pillar inner plate 500 gradually decreases. A structural insert 400 is installed at the point A where the cavity of the B-pillar reinforcement 100 decreases. The structural insert 400 fills the cavity between the B-pillar reinforcement 100 and the B-pillar inner plate 500 to increase the local strength of the B-pillar, so that the local part of the B-pillar can effectively reduce bending, avoid or reduce a large amount of intrusion, and can effectively deal with side collisions. The structural insert 400 plays a role of local reinforcement as a whole, which is better than sheet metal and lighter in weight.
[0047] Please refer to Figure 7-Figure 8 In some embodiments of the present application, the structural insert 400 includes a frame and a filling piece, and the frame is embedded in the filling piece; the frame and the filling piece are made of different materials, and the hardness of the frame is greater than the hardness of the filling piece.
[0048] The structural insert 400 is disposed between the B-pillar reinforcement 100 and the B-pillar inner plate 500, and is connected to the B-pillar reinforcement 100. In order to play a good role in local reinforcement, the structural insert 400 is configured to include a skeleton and a filler, and the hardness of the skeleton is greater than the hardness of the filler. The structural insert 400 can be a casting. During the manufacturing process, the skeleton is first placed in a mold as an inlay, and then the filler is injected to finally obtain the structural insert 400.
[0049] Please refer to Figure 7-Figure 8 In some embodiments of the present application, the material of the skeleton includes nylon composite material; and / or the material of the filling piece includes epoxy resin structural adhesive.
[0050] The hardness of the skeleton is greater than that of the filling piece. The skeleton may be made of a nylon composite material PA6+GF35 or other materials with high hardness. The filling piece may be made of epoxy resin structural adhesive HC SNS 9020.
[0051] Please refer to Figure 7-Figure 8 In some embodiments of the present application, the structural insert 400 includes a connector 401 , which is connected to the edge of the frame, and the frame is connected to the B-pillar reinforcement 100 through the connector 401 ; and / or, a reinforcement structure is also provided on the structural insert 400 .
[0052] The connecting member 401 includes two metal sheets, which are connected to the edge of the frame. Preferably, the two metal sheets are respectively located at the upper and lower ends of the structural insert 400 to improve the connection stability between the structural insert 400 and the B-pillar reinforcement 100; the two metal sheets are fixed on the B-pillar reinforcement 100. Preferably, the two metal sheets are fixed on the B-pillar reinforcement 100 by spot welding to improve the connection strength between the structural insert 400 and the B-pillar reinforcement 100.
[0053] The structural insert 400 is also provided with a reinforcement structure. The structural insert 400 as a whole may be a mesh structure, including a rib-shaped reinforcement structure, which can reduce weight and improve the bending section modulus. In the structural insert 400 where the openings are densely packed or the strength is weak, the structural insert 400 may increase the strength by locally increasing the density of the ribs.
[0054] Please refer to Figure 1-Figure 2 In some embodiments of the present application, the vehicle body pillar further includes a first baffle 200 and a second baffle 300 . The first baffle 200 and the second baffle 300 are spaced apart between the B-pillar reinforcement 100 and the B-pillar inner panel 500 , and are connected to different positions of the B-pillar reinforcement 100 .
[0055] The structures of the first baffle 200 and the second baffle 300 may be the same. The first baffle 200 and the second baffle 300 support the cavity between the B-pillar reinforcement 100 and the B-pillar inner panel 500 to increase the structural strength and reduce the intrusion amount during a side collision.
[0056] The first baffle 200 and the second baffle 300 are both fixedly connected to the B-pillar reinforcement 100. Preferably, the first baffle 200 and the second baffle 300 can be fixed to the B-pillar reinforcement 100 by welding; due to the influence of the welding process, the first baffle 200 and the second baffle 300 are both separated from the B-pillar inner panel 500.
[0057] The first baffle plate 200 and the second baffle plate 300 are both provided with flanges for welding, so as to facilitate welding of the first baffle plate 200 and the B-pillar reinforcement 100 and welding of the second baffle plate 300 and the B-pillar reinforcement 100 .
[0058] The shape of the first baffle 200 is compatible with the inner shape of the B-pillar reinforcement 100, and the shape of the second baffle 300 is also compatible with the inner shape of the B-pillar reinforcement 100. After the first baffle 200 and the B-pillar reinforcement 100 are welded, the first baffle 200 and the B-pillar reinforcement 100 are fitted together; after the second baffle 300 and the B-pillar reinforcement 100 are welded together, the second baffle 300 and the B-pillar reinforcement 100 are fitted together.
[0059] Positioning holes are set on the first baffle 200, the second baffle 300 and the B-pillar reinforcement 100. When welding is required, the first baffle 200 and the B-pillar reinforcement 100 are first connected by pins and then welded, and the second baffle 300 and the B-pillar reinforcement 100 are first connected by pins and then welded, which facilitates welding positioning and improves the accuracy of the welding position.
[0060] Please refer to Figure 3-Figure 4 In some embodiments of the present application, the B-pillar reinforcement 100 includes a B-pillar upper reinforcement 101 and a B-pillar lower reinforcement 102 , the strength of the B-pillar upper reinforcement 101 is higher than that of the B-pillar lower reinforcement 102 , the B-pillar upper reinforcement 101 and the B-pillar lower reinforcement 102 are welded, and a B-pillar reinforcement welding line 103 is formed between the B-pillar upper reinforcement 101 and the B-pillar lower reinforcement 102 .
[0061] The B-pillar reinforcement 100 includes a B-pillar upper reinforcement 101 and a B-pillar lower reinforcement 102 fixedly connected by welding. The welding between the B-pillar upper reinforcement 101 and the B-pillar lower reinforcement 102 adopts the hot forming laser welding technology, and the B-pillar reinforcement welding line 103 is the B-pillar reinforcement welding line. Laser welding uses laser energy to automatically assemble and weld a number of steels, stainless steels, aluminum alloys, etc. of different materials, thicknesses, and coatings to form an integral plate, profile, sandwich panel, etc., so as to meet the different requirements of parts for material properties and achieve lightweight equipment with lighter weight, better structure and better performance.
[0062] Below the B-pillar reinforcement welding line, the cavity cross-section of the B-pillar reinforcement is the largest, and the cavity becomes smaller and smaller upward until it is zero. The B-pillar upper reinforcement 101 uses high-strength anti-intrusion materials CA1000 / 1400HS+AS or CA1100 / 1700HS+AS, and the B-pillar lower reinforcement 102 uses low-strength and better-collapse CA370 / 550HS+AS or CA800 / 1000HS+AS. When a side collision occurs, the B-pillar lower reinforcement 102 of the B-pillar reinforcement 100 first meets the side collision impact force, and the B-pillar lower reinforcement 102 is required to absorb the impact energy. Therefore, the area below the B-pillar reinforcement welding line can be a collision energy absorption zone, and the B-pillar lower reinforcement 102 can use a softer material to make the lower section of the B-pillar easier to collapse and absorb energy. The material grade and thickness selection of the B-pillar lower reinforcement 102 are more flexible, the material utilization rate is higher, the hot forming process control is less difficult, and the performance is more stable.
[0063] Please refer to Figure 6 In some embodiments of the present application, the B-pillar inner panel 500 includes a B-pillar upper inner panel 501 and a B-pillar lower inner panel 502. The strength of the B-pillar upper inner panel 501 is higher than that of the B-pillar lower inner panel 502. The B-pillar upper inner panel 501 and the B-pillar lower inner panel 502 are welded, and a B-pillar inner panel welding line 503 is formed between the B-pillar upper inner panel 501 and the B-pillar lower inner panel 502.
[0064] The B-pillar inner panel 500 includes a B-pillar upper inner panel 501 and a B-pillar lower inner panel 502 fixedly connected by welding. The welding between the B-pillar upper inner panel 501 and the B-pillar lower inner panel 502 adopts hot forming laser welding technology, and the B-pillar inner panel welding line 503 is the B-pillar inner panel welding line.
[0065] The upper inner panel 501 of the B-pillar is made of high-strength and anti-intrusion materials CA1000 / 1400HS+AS or CA1100 / 1700HS+AS, and the lower inner panel 502 of the B-pillar is made of low-strength and better-collapse CA370 / 550HS+AS or CA800 / 1000HS+AS. When a side collision occurs, the lower part of the B-pillar is first hit by the side collision force, and the lower inner panel 502 of the B-pillar is required to absorb the collision energy. Therefore, the area below the welding line of the B-pillar inner panel can be a collision energy absorption area, and the lower inner panel 502 of the B-pillar can be made of a softer material to make the lower section of the B-pillar easier to collapse and absorb energy. The material grade and thickness selection of the lower inner panel 502 of the B-pillar are more flexible, the material utilization rate is higher, the hot forming process is less difficult to control, and the performance is more stable.
[0066] By using laser welding technology and setting a structural insert 400, the B-pillar forms a structure that is strong at the top and weak at the bottom. During a side collision, the upper section of the B-pillar is strong, has a small intrusion amount, and is relatively far away from the head of the person, thereby avoiding or reducing the impact on the head; the lower section of the B-pillar is weak, has a large deformation absorption energy, and can have an appropriate intrusion amount. Since there is a seat protection in the intrusion direction of the lower part of the B-pillar, the occupants will not suffer fatal injuries, which is beneficial to the absorption and transmission of energy during a side collision, thereby protecting the safety of people and property in the passenger compartment, and enabling the vehicle to effectively cope with side collisions.
[0067] Laser welding technology can also be replaced by thermoforming soft zone technology. Thermoforming soft zone technology is an important way to achieve lightweight automobiles. Its characteristics are to achieve variable strength, thin material thickness and low weight design of parts through mold water cooling and electric heating system.
[0068] Please refer to Figure 4-Figure 6 In some embodiments of the present application, the B-pillar reinforcement welding line 103 is lower than the B-pillar inner panel welding line 503 .
[0069] The B-pillar reinforcement welding line 103 is the B-pillar reinforcement tailored welding line, and the B-pillar inner panel welding line 503 is the B-pillar inner panel tailored welding line. The B-pillar inner panel tailored welding line is about 35 mm higher than the B-pillar reinforcement welding line.
[0070] Please refer to Figure 1 and Figure 4 In some embodiments of the present application, the first baffle 200 and the second baffle 300 are both arranged opposite to the B-pillar reinforcement welding line 103 .
[0071] The first baffle 200 and the second baffle 300 are connected to different positions of the B-pillar reinforcement 100. Specifically, the first baffle 200 and the second baffle 300 are welded on the B-pillar reinforcement welding line 103 to support the cavity between the B-pillar reinforcement 100 and the B-pillar inner panel 500 to increase the structural strength and reduce the intrusion amount during side collision.
[0072] A first partition 200 and a second partition 300 may also be provided at a location with weak strength, and the number of partitions may be increased or decreased according to actual needs.
[0073] In a second aspect, an embodiment of the present application provides a vehicle, including a vehicle body and a vehicle body pillar, wherein the vehicle body pillar is mounted on the vehicle body. The vehicle includes a vehicle body, and a vehicle B-pillar is provided between a front door area and a rear door area of the vehicle body, and the vehicle B-pillar meets a side collision.
[0074] The various embodiments or implementation methods in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referenced to each other.
