Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
According to an aspect of the present invention, there is provided a vehicle body door frame structure, as shown in fig. 5 to 10, including: a column 10; a sill beam 20 being a general beam or a section taken from a general beam; and a connecting member 30 connected to the rocker beam 20 and protruding from a first end of the rocker beam 20 in an extending direction of the rocker beam 20, the connecting member 30 being connected to the pillar 10.
The connecting piece 30 of the vehicle body door frame structure is protruded out of the threshold beam 20 and connected with the upright post 10, namely the connecting piece 30 is matched with the upright post 10, and the shape of the end part of the threshold beam 20 is not required to be matched with the shape of the upright post 10, so that the threshold beam 20 can be used as a universal piece applicable to various vehicle types for mass production, namely a universal beam for mass production, and then the mass production universal beam with the proper length is selected as the threshold beam 20 according to different vehicle types or a section with the proper length is cut from the universal beam to be used as the threshold beam 20, so that different connecting pieces 30 are designed according to different vehicle types and different upright posts 10, and the connection between the universal threshold beam 20 and different upright posts 10 can be realized.
Therefore, the vehicle body door frame structure can enable the threshold beam 20 to be produced in mass in a universal mode, simplifies the processing technology compared with the threshold beam 20' in the prior art, shortens the processing time, and achieves the effects of improving the production efficiency and saving raw materials. The shape and structure of the universal sill as a universal member are the same, that is, since the rocker beam 20 is a universal beam or a portion of a universal beam, the shape of the rocker beam 20 in the length direction is the same or regularly repeated, the plate type and structure of the rocker beam 20 are not affected by the difference in the shapes of the pillar 10 and the connector 30 or the difference in the vehicle type, and the rocker beams 20 of the same plate type and the same structure can be fitted with the pillars 10 of various structures to form the door frame structure of the vehicle body for various vehicle types.
Preferably, a section of the connecting member 30 connected to the rocker beam 20 is shaped to match the shape of the rocker beam 20, and a section of the connecting member 30 protruding from the rocker beam 20 is shaped to match the shape of a section of the pillar 10 to which the connecting member 30 is connected.
Specifically, the rocker beam 20 has a first reinforcement structure 21 provided in the longitudinal direction, and the connecting member 30 has a second reinforcement structure 31, and the first reinforcement structure 21 and the second reinforcement structure 31 are fitted at the position where the rocker beam 20 is connected to the connecting member 30. In the embodiment shown in fig. 5 to 9, the first reinforcing structure 21 is a reinforcing groove formed in a U-shaped structure, and the second reinforcing structure 31 is a bowl-shaped groove opened at one side.
Preferably, the upright 10 has a third reinforcing structure 13, and the third reinforcing structure 13 is a U-shaped structure or a reinforcing groove.
The door frame structure of the vehicle body of the present invention further includes a connecting member 30 connected to the rocker beam 20, the connecting member 30 having a shape to be fitted to the pillar 10, and in some embodiments, the connecting member 30 is a part independently designed and processed according to different vehicle models, and is connected to the rocker beam 20 as a mass-produced part so that the rocker beam 20 can be adapted to different vehicle models. Further, the connection of the connecting member 30 to the pillar 10 also strengthens the connection strength of the rocker beam 20 to the pillar 10, thereby maintaining the strength of the door frame structure of the vehicle body while simplifying the structure of the rocker beam 20.
Because the length of the threshold beam is longer, in order to process the threshold beam 20' in the prior art, a large-volume processing die is needed, and because different vehicle models and different upright posts need to be designed separately, a processing die is needed for each vehicle model, which causes the increase of the manufacturing cost and the increase of the process flow. By adopting the car body door frame structure, the universal beam can be produced in batch by adopting one mould, the mould for processing the connecting piece 30 is only needed to be designed according to different car models and different upright posts, and the processing mould with smaller volume can be used for processing because the length and the volume of the connecting piece 30 are smaller than those of the sill beam 20.
Preferably, as shown in fig. 5, 6 and 9, in the lengthwise direction of the rocker beam 20, the edge of the pillar 10 remote from the rocker beam 20 includes a first pillar edge structure 14, and the edge of the connecting member 30 remote from the rocker beam 20 includes a connecting member edge structure 32, and the connecting member edge structure 32 is fitted to the first pillar edge structure 14.
Wherein the first pillar edge structure 14 is an edge extension structure of the edge of the pillar 10, i.e. a plate parallel to the paper surface in fig. 5; the connector edge structure 32 is an edge extension structure of the connector 30, i.e. a plate parallel to the paper in fig. 5. When the door frame structure of the vehicle body is formed, the first pillar side structure 14 and the connecting member side structure 32 are joined to each other to form a single body.
More preferably, as shown in fig. 5, 9 and 10, a section of the connecting member 30 connected to the rocker beam 20 overlaps a section of the rocker beam 20 at the first end and is connected thereto by a fastener, welding or crimping. This is a press or roll connection.
In addition, the rocker beam 20 of the vehicle body doorframe structure of the present invention may not be subjected to cutting in the width direction, so that the width of the rocker beam 20 is not changed, i.e., it may be formed not only by press molding but also by roll molding, and the finished shape of the structural strength is integrally reinforced, which may have better mechanical properties.
Preferably, the connecting member 30 extends to a side edge region of the pillar 10. In some embodiments, the rocker beam 20 does not extend to the edge of the pillar 10, and thus the connecting member 30 is provided to extend to the edge of the pillar 10, thereby maintaining structural integrity.
Preferably, the rocker beam 20 is roll formed or punch formed. Namely, the universal beam is formed by rolling or punching. The prior art rocker beam 20' as shown in fig. 1 and 3 includes a trim structure and thus can be formed only by stamping and cannot be roll formed. The rocker beam 20 of the present invention shown in fig. 5 to 8 is a general beam having a constant width in the extending direction, and thus can be formed not only by press molding but also by roll molding, and has superior mechanical properties compared to the rocker beams of the prior art because the roll-formed part has better mechanical properties such as strength than the press-formed part.
In addition, in the present embodiment, the edges of the rocker beam 20 are linear, and thus, the processing is facilitated. And because the threshold beam 20 is not trimmed, the waste of materials is avoided.
It is to be noted that since the rocker beam 20 is a general beam or a part of a general beam, the shape of the rocker beam 20 in the length direction is identical or regularly repeated, i.e. as in the embodiment shown in fig. 7.
Preferably, as shown in fig. 9, the connecting member 30 has the same width as the rocker beam 20.
Preferably, as shown in fig. 5 and 6, the column 10 includes a body 11 and a column base 12, and the connecting member 30 overlaps and is connected to at least a portion of the column base 12. In the embodiment shown in the drawings, the column shoe 12 encloses the connecting member 30 and a portion of the rocker beam 20, and the column shoe 12 extends to a position intermediate the connecting member 30 and the rocker beam 20 in the width direction. For better strength, the column shoe 12 encases and overlaps both the rocker beam 20 and the connecting member 30. Further, the column shoe 12 is directly connected to the connecting member 30 and directly connected to the rocker beam 20. That is, the column shoe 12 overlaps with and is connected to not only the rocker beam 20 and the connecting member 30. In a specific connection mode, the column base 12 and the connecting piece 30 can be connected through a fastener, welding or crimping. And the column shoe 12 and the rocker beam 20 may be connected by a fastener, welding, or crimping. The connection between the column shoe 12 and the connecting member 30 may be the same as or different from the connection between the column shoe 12 and the rocker beam 20.
In other embodiments, the column shoe 12 is directly connected to the connecting member 30 to overlap the rocker beam 20, which is simpler and has sufficient strength.
Preferably, as shown in fig. 6, the column shoe 12 covers at least a portion of the side of the rocker beam 20 and covers at least a portion of the side of the connecting member 30. The side of the rocker beam 20 refers to the plate surface of the rocker beam 20 on the side shown in fig. 6, and the side of the connecting member 30 refers to the plate surface of the connecting member 30 on the side shown in fig. 6. The column shoe 12 covers both the rocker beam 20 and the side of the connecting piece 30, with a corresponding increase in structural strength.
Preferably, a portion of the column shoe 12 protrudes from the body 11 in the extending direction of the rocker beam 20, and the portion of the column shoe 12 protruding from the body 11 covers the side of the rocker beam 20. The pedestal 12 is provided to protrude so as to facilitate its connection with the rocker beam 20.
More preferably, as shown in fig. 6, the pillar 10 is connected to a surface of the rocker beam 20 located inside the door frame structure of the vehicle body. I.e. the threshold beam 20 is located outside the pillar 10.
In the embodiment shown in fig. 5 and 6, the pillar 10 comprises a body 11 and a pillar base 12, at least one section of the pillar base 12 extending in the length direction of the rocker beam 20, the pillar base 12 having a second pillar edge structure 15 at the upper edge of the section extending in the length direction of the rocker beam 20, the rocker beam edge structure 22 at the upper edge of the rocker beam 20, the rocker beam edge structure 22 being adapted to the second pillar edge structure 15.
The second column edge structure 15 is similar to the first column edge structure 14 and is a flanging structure, namely a plate parallel to the paper surface; as shown in fig. 8, the rocker edge structure 22 is an edge extension of the rocker, which in fig. 8 is a sheet perpendicular to the plane of the paper. When the door frame structure of the vehicle body is formed, the second pillar side structure 15 and the rocker side structure 22 are joined together.
Taking the example shown in fig. 6 as an example, the pillar 10 has the third reinforcement structure 13, and the rocker sill 20 has the first reinforcement structure 21, so that the second pillar edge structure 15 and the rocker edge structure 22 can overlap, and therefore, in the direction of fig. 6, the first reinforcement structure 21 and the third reinforcement structure 13 each project toward the outside of the paper, that is, the first reinforcement structure 21 projects toward the pillar 10, and the third reinforcement structure 13 projects away from the rocker sill 20, which can achieve the overlapping relationship shown in fig. 6.
Preferably, as shown in fig. 5 and 10, the door frame structure of the vehicle body further includes a reinforcement panel 40, and the reinforcement panel 40 is connected to both the rocker beam 20 and the connecting member 30. In order to further reinforce the structure, the vehicle body doorframe structure is further provided with a reinforcement panel 40, which is used to connect the rocker beam 20 and the connecting member 30, unlike the prior art connecting reinforcement panel 40', thereby improving the strength of the vehicle body doorframe structure.
Preferably, the width of the reinforcement panel 40 is less than the width of the rocker beam 20. Since the reinforcement plate 40 mainly serves to reinforce the strength of the connection between the rocker beam 20 and the connecting member 30, the reinforcement plate 40 does not need to have the same width as the rocker beam 20.
Preferably, the pillar 10 and the reinforcement panel 40 are attached to opposite sides of the rocker beam 20, respectively. That is, the reinforcement plate 40 is connected to the outer side surface of the rocker beam 20 at the door frame structure of the vehicle body. It can be seen that the reinforcement plate 40 and the pillar 10 clamp the rocker 20 and the connector 30, which enhances the strength of the rocker 20 and the connector 30 in the direction perpendicular to the plane of the drawing and prevents the rocker 20 and the connector 30 from being folded.
According to another aspect of the present invention, there is also provided a vehicle including a vehicle body door frame structure, which is the above-described vehicle body door frame structure.
The mode of connection between the rocker beam 20 and the pillar 10 of the door frame structure of the vehicle body of the present invention can be used in various locations of the vehicle, such as the connection of the rocker beam of the front or rear door with the a-pillar or with the B-pillar.
According to another aspect of the present invention, there is also provided a method of manufacturing a door frame structure for a vehicle body, wherein the door frame structure for a vehicle body includes a pillar 10 and a rocker beam 20, the method comprising: selecting a proper general beam as the threshold beam 20 or cutting a section of the general beam along the length direction to be used as the threshold beam 20; mounting a connecting member 30 at a first end of the threshold beam 20 in a length direction thereof such that the connecting member 30 protrudes from the first end; the upright 10 and the connecting member 30 are connected.
That is, the present invention also provides a method for manufacturing the above-mentioned door frame structure for a vehicle body, wherein the general-purpose beam is a general mass-produced member, and can be press-formed or roll-formed from a single plate, the length of the entire general-purpose beam can be longer than any one of the threshold beams 20 or the same as the longest threshold beam 20, and a section of the general-purpose beam is cut out as the threshold beam 20 according to different vehicle types, thereby simplifying the manufacturing process of the threshold beam 20 and improving the manufacturing efficiency.
Preferably, the manufacturing method further comprises: the reinforcement panel 40 is coupled to both the rocker beam 20 and the connecting member 30 before or after the pillar 10 and the connecting member 30 are coupled.
In both embodiments, namely, the reinforcing plate 40 is installed before the pillar 10 is connected and the reinforcing plate 40 is installed after the pillar 10 is connected, the reinforcing plate 40 is installed before the pillar 10 is connected, so that the connection strength between the rocker beam 20 and the connecting member 30 can be further improved, and thus a greater load can be borne when the pillar 10 is connected, and the strength of the door frame structure of the vehicle body can be improved.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
