All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
The embodiment of the invention provides an extraction method of a vehicle body connection technology, which comprises the following steps of:
step S10: a plurality of vehicle body connection schemes are obtained, wherein the vehicle body connection schemes comprise vehicle body materials and vehicle body connection technologies. The vehicle connection scheme in the embodiment of the invention refers to a connection scheme for connecting vehicle bodies made of two different materials or made of the same material. For example:
scheme 1: the three-layer aluminum alloy plates are overlapped, the width of the overlapping edge is 24mm (larger than 23mm), the thickness of the bottom layer plate is 1/2 (larger than 1/3) of the thickness of the total overlapping plate, and the three-layer aluminum alloy plates are connected through an aluminum alloy resistance spot welding process (RSW).
Scheme 2: the lapping mode between two-layer aluminum alloy plate is lapping, the width of the lapping edge is 22mm (more than 21mm and less than 23mm), the thickness of the bottom plate layer is 1/2 (more than 1/3) of the thickness of the total lapping plate, and the two-layer aluminum alloy plate is riveted by self-punching (SPR)
) And bonding with glue.
Scheme 3: the composite material with the thickness of 3.8mm (less than 4mm) is arranged above the aluminum alloy profile with the thickness of 15.5mm (more than 15mm), the composite material and the aluminum alloy profile are in a lap joint structure and are connected in a mode of combining Flow Drilling Screws (FDS) and gluing.
Step S20: and establishing a hypercube model according to the vehicle body material and the vehicle body connection technology.
Because the automobile body material has a plurality of, and the combination of automobile body material is diversified, and each combination of automobile body material corresponds to multiple connection technique again, through generalizing and clustering automobile body material characteristic, connection technique attribute and the corresponding relation between the two in a large amount of automobile body connection schemes, can obtain corresponding different automobile body material multiple connected mode, for example: the following vehicle body connecting technologies can be obtained by researching a large number of vehicle body connecting schemes among the aluminum alloy plates:
vehicle body connection technology 1: overlapping the three layers of aluminum alloy plates to enable the width of overlapping edges to be larger than 23mm, enabling the thickness of the bottom plate to be larger than 1/3 of the total overlapping plate thickness, and finally connecting through an RSW process;
vehicle body connection technology 2: overlap joint is carried out to two-layer aluminum alloy plate through the overlap joint mode, makes overlap joint limit width be greater than 21mm, is less than 23mm, and bottom plate panel thickness is greater than 1/3 of total overlap joint panel thickness, passes through SPR at lastAnd connecting in a manner of combining with gluing.
In the specific embodiment, the vehicle body connection technologies corresponding to the vehicle body connection schemes grouped into different vehicle body materials are obtained by researching a large amount of data, and finally a hypercube model is obtained according to the research result, wherein the hypercube model includes a plurality of paths which are interlaced with each other, and each path can obtain one corresponding connection technology, for example, the two vehicle body connection technologies for the aluminum alloy sheet material exemplified above are two paths in the hypercube model.
Step S30: the vehicle body connecting technology 1 and the vehicle body connecting technology 2 can be generated by the hypercube model according to the target material and the hypercube model, for example, if the target material is an aluminum alloy plate.
The extraction method of the vehicle body connection technology provided by the invention comprises the steps of firstly establishing a hypercube model according to vehicle body materials and the vehicle body connection technology in the known vehicle body connection scheme, and then generating the vehicle body connection technology corresponding to target materials according to the target materials and the hypercube model. The hypercube model is constructed by a large number of known vehicle body connection schemes, so that target materials are input into the hypercube model, and the connection technology corresponding to the target materials can be rapidly and comprehensively acquired.
In one embodiment, if the target material is an aluminum alloy sheet, at least two joining techniques as illustrated in step S20 can be generated by the hypercube model.
In an alternative embodiment, as shown in fig. 2, the step S20 specifically includes:
step S21: extracting the material characteristics of the vehicle body material and the technical attributes of the vehicle body connecting technology.
Step S22: and determining the corresponding relation between the material characteristics and the technical attributes according to the corresponding relation between the vehicle body materials and the vehicle body connection technology in the plurality of vehicle body connection schemes. For example, in the above aspect 1, the vehicle body joining technique corresponding to the aluminum alloy plate material is: the three layers are overlapped, the width of the overlapping edge is 24mm (larger than 23mm), the thickness of the bottom layer plate is 1/2 (larger than 1/3) of the total thickness of the overlapping plate, and the three layers are connected through an aluminum alloy resistance spot welding process (RSW).
Step S23: and establishing a hypercube model according to the corresponding relation between the material characteristics and the technical attributes.
Because the hypercube model is established by the corresponding relation between the material characteristics and the technical attributes, even if the prior art does not have the vehicle body connection technology corresponding to the target material, the technical attributes corresponding to the material characteristics can be obtained according to the material characteristics of the target material, then the vehicle body connection technology containing the attributes is determined through the technical attributes, or the novel vehicle body connection technology with the attributes is obtained through the combination of various vehicle body connection technologies, and the inspiration is provided for related technicians, so that a complete vehicle body connection scheme is obtained.
In an alternative embodiment, as shown in fig. 3, the step S30 specifically includes:
step S31: and acquiring the material characteristics of the target material. The target material includes at least one material property.
Step S32: one or more technical attributes corresponding to the material properties of the target material are obtained from the material properties of the target material and the hypercube model.
The multi-cube model is constructed on the basis of researching a large number of vehicle connection schemes, the same vehicle body material can be subjected to a plurality of different vehicle body connection technologies, and the different vehicle body connection technologies have different technical attributes, so that one or more technical attributes can be obtained according to the target material and the multi-cube model.
Step S33: and generating a vehicle body connecting technology according to the technical attributes.
If only one technical attribute is obtained in the above step S32, the finally obtained vehicle body joining technique necessarily has the technical attribute, but if a plurality of technical attributes are obtained in the above step S32, all the technical attributes need not be all concentrated in one vehicle body joining technique. It should be noted that not all the technical attributes and the vehicle body connection technologies are in a one-to-one correspondence relationship, and if one technical attribute can correspond to a plurality of vehicle body connection technologies, a plurality of vehicle body connection technologies can be generated according to the technical attribute.
In an alternative embodiment, as shown in fig. 4, after step S30, the method for extracting a vehicle body connection technology according to an embodiment of the present invention further includes:
step S40: and determining a vehicle body connecting scheme containing the target material and the vehicle body connecting technology according to the target material and the vehicle body connecting technology.
If there is a vehicle body connection scenario including the target material and the vehicle body connection technology generated through step S30, the scenario may be output to provide a reference for the user, for example, if the vehicle body connection technology 1 illustrated in step S20 is available through step S30, the vehicle body connection scenario 1 illustrated in step S10 may be correspondingly output.
If the vehicle body connection scenario generated in step S30 is not the prior art and there is no corresponding vehicle body connection scenario, step S40 need not be performed.
In an alternative embodiment, as shown in fig. 5, after step S30, the method for extracting a vehicle body connection technology according to an embodiment of the present invention further includes:
step S50: and judging whether at least two vehicle body connecting technologies are generated or not, if so, executing the step S51, and if only one vehicle body connecting technology is generated, not executing any operation.
Step S51: and calculating the connection cost of each vehicle body connection technology according to the generated connection process, connection structure and target material of each vehicle body connection technology. For example, in the two vehicle body joining techniques illustrated in the above step S20, the joining process and the joining structure are different, and the difference in the joining process and the joining structure causes the joining costs of the two vehicle body joining techniques to be different.
Step S52: and determining a target vehicle body connecting technology according to the connecting cost. On the premise of ensuring the stability, the vehicle body connection technology with lower cost can be determined as the target vehicle body connection technology.
In an alternative embodiment, as shown in fig. 6, after step S30, the method for extracting a vehicle body connection technology according to an embodiment of the present invention further includes:
step S60: and judging whether at least two vehicle body connecting technologies are generated or not, if at least two vehicle body connecting technologies are generated, executing the step S61, and if only one vehicle body connecting technology is generated, not executing any operation.
Step S61: the installation position of the target material is obtained, and the installation position can comprise a vehicle roof, a vehicle door and the like.
Step S62: and determining a target vehicle body connecting technology according to the installation position.
In one embodiment, different requirements are placed on the stability, ease of handling, etc. of the body connection technology due to the different mounting positions. For example, for a position with a high temperature during vehicle starting, a vehicle body connection technology including a glue joint process can be avoided as much as possible, because the high temperature affects the stability of glue, thereby negatively affecting the stability of a joint, a vehicle body connection technology with stability not easily affected by external impact can be selected for a position which is easily impacted, and a vehicle body connection technology which is easily operated can be selected for a position which is difficult to operate, which is only exemplified above, and an optimal vehicle body connection technology can be selected as a target vehicle body connection technology according to actual requirements during specific implementation.
