Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0045] Please refer to Figure 1 , Figure 1 which is a schematic diagram of an application environment of the product model acquisition method provided by an embodiment of the present invention. As Figure 1 shown, the terminal device 10 is communicatively connected to the server 20. Among them, the number of terminal devices 10 is one or more, and the embodiments of the present invention do not limit this.

[0046] In this embodiment, a copy model associated with the original model is stored on the server 20. When a user needs to design a product, instead of downloading the original model, the user only needs to download the copy model through the terminal device 10, and then a product model can be obtained thereby.

[0047] In this embodiment, the terminal device 10 may be a personal computer (PC), a laptop computer, a tablet computer, a server, a mobile phone, etc., and the present invention does not limit this.

[0048] Please refer to Figure 2 , Figure 2 which is a block diagram of a terminal device provided by an embodiment of the present invention. The terminal device 10 includes a memory 210, a processor 220, and a communication module 230. The memory 210, the processor 220, and the communication module 230 are directly or indirectly electrically connected to each other to achieve data transmission or interaction. For example, these elements may be electrically connected to each other through one or more communication buses or signal lines.

[0049] Among them, the memory 210 is used to store programs or data. The memory 210 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Programmable Read-Only Memory (EPROM), an Electric Erasable Programmable Read-Only Memory (EEPROM), etc.

[0050] The processor 220 may be an integrated circuit chip with signal processing capabilities. The processor 220 may be a general-purpose processor, including a Central Processing Unit (CPU for short), a Network Processor (NP for short), etc.; it may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. It can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present application. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc.

[0051] Among them, the processor is used to read and write the data or programs stored in the memory 210 and execute corresponding functions. For example, when the processor 220 executes the computer program stored in the memory 210, it can implement the product model acquisition method disclosed in each embodiment of the present invention.

[0052] The communication module 230 is used to establish a communication connection between the terminal device 10 and the server 20 through the network and is used to send and receive data through the network.

[0053] It should be understood that Figure 2 The structure shown is only a schematic diagram of the structure of the terminal device 10, and the terminal device 10 may also include Figure 2 more or fewer components than those shown, or have a configuration different from that Figure 2 shown. Figure 2 The components shown may be implemented using hardware, software, or a combination thereof.

[0054] The embodiments of the present invention also provide a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it can implement the product model acquisition method disclosed in the embodiments of the present invention.

[0055] In the prior art, when designing mechanical products, it is necessary to download and use a model with complete mechanical components. However, such a model file is large and has rich details. When downloading through a terminal device, it has relatively high requirements for the hardware and network speed of the terminal device, resulting in low design efficiency.

[0056] Based on the above problems, in order to reduce the requirements for the hardware and network speed of the terminal device and improve the design efficiency, an embodiment of the present invention provides a method for obtaining a product model. Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a method for obtaining a product model provided by an embodiment of the present invention. The method includes:

[0057] Step S310, in response to a user's model download operation, send a model download request to the server; the model download request carries a target identifier, so that the server can determine a target copy model with the target identifier from multiple copy models associated with the original models.

[0058] Optionally, the server stores multiple original models and copy models associated with each original model, and the copy models are obtained by simplifying the original models.

[0059] It should be noted that in practical applications, the original models are drawn by the user using mechanical design software on the terminal device 10. The mechanical design software can be Computer Aided Design (CAD), 3D Mechanical Design System (SolidWorks), Automated NC Programming Software (Edgecam), etc., which are not limited in the embodiments of the present invention. In this embodiment, the user can search using the identifier of the copy model as a keyword, so that the terminal device 10 sends a download request carrying the user input identifier to the server 20, and then determines a copy model with the above identifier from the server.

[0060] Step S320, receive the target copy model returned by the server.

[0061] Step S330, obtain a target product model according to the obtained target copy model.

[0062] Optionally, the number of copy models that make up the product model is not limited and can be obtained according to actual needs. For example, when only one copy model of the product model is required, the obtained target copy model can be directly used as the target product model; when multiple copy models of the product model are required, the user, according to the requirements, sequentially performs a download operation through the terminal device 10, sends a model download request to the server 20, and then obtains multiple target copy models. Then, the obtained multiple target copy models are assembled, that is, the multiple target copy models are assembled according to the requirements of the product design to obtain the target product model.

[0063] The product model acquisition method provided by the embodiments of the present invention responds to the user's model download operation, sends a model download request to the server, and the model download request carries a target identifier, so that the server can determine a target copy model with the target identifier from the copy models associated with multiple original models. The terminal device receives the target copy model returned by the server and obtains the target product model based on the obtained target copy model; wherein, the copy model is obtained by simplifying the original model, the file size of the copy model is smaller than that of the original model, and each original model is associated with a copy model. When it is necessary to design and obtain the target product model, only the target copy model needs to be downloaded, which reduces the requirements for the hardware and network speed of the terminal device, and thus improves the efficiency.

[0064] In this embodiment, the original model and the copy model are uploaded by the terminal device 10 to the server 20 for storage. Optionally, please refer to Figure 4 , Figure 4 which is another schematic flowchart of the product model acquisition method provided by the embodiments of the present invention. The above method further includes:

[0065] Step S340: Simplify the obtained original model to obtain a copy model.

[0066] Optionally, the original model contains complete components, and the copy model includes other components in the original model except for the confidential components and the components irrelevant to the design. It can be understood that the original model contains confidential components, components irrelevant to the design, and the components in the copy model.

[0067] Step S350: Establish an association relationship between the original model and the copy model.

[0068] In this embodiment, the original model corresponds to a first identifier, and the copy model corresponding to the original model corresponds to a second identifier, and the second identifier is obtained by modifying the first identifier.

[0069] Optionally, the above first identifier and second identifier can be the file name of the model or the drawing number of the model, and are not limited in the implementation of the present invention.

[0070] In an alternative embodiment, the above first identifier and second identifier are drawing numbers. Specifically, the drawing numbers can be set according to actual needs and are not limited in the implementation of the present invention. For example, the first identifier corresponding to the original model is set as "JS-HL-0000-A-D", and the second identifier corresponding to the copy model of the original model is set as "JS-HL-0000-A-D1" after modifying the first identifier, that is, adding the suffix "1" to the first identifier as the second identifier. It should be noted that the method of modifying the first identifier to obtain the second identifier is also not limited in the implementation of the present invention.

[0071] Optionally, an association relationship between the original model and the copy model is established according to the first identifier and the second identifier.

[0072] Step S360: Upload the original model, the copy model corresponding to the original model, and the association relationship to the server for storage.

[0073] In one example, an application program is installed in the terminal device 10, and the application program corresponds to the server 20. The terminal device 10 can interact with the server 20 through the application program. For example, the original model, the copy model corresponding to the original model, and the association relationship can be uploaded to the server 20 for storage.

[0074] In the present embodiment, the attribute information of the copy model is also recorded in the association relationship, and the material information corresponding to each original model is also stored in the server. It can be understood that after obtaining the product model and entering production, in order to accurately obtain the material information, optionally, please refer to Figure 5 , Figure 5 which is another schematic flowchart of the product model acquisition method provided by the embodiment of the present invention. The method further includes:

[0075] Step S370: Determine the second identifier of the target copy model that constitutes the target product model.

[0076] Optionally, when it is necessary to obtain the material information of the target product model, only the second identifier of the target copy model that constitutes the target product model needs to be determined to find the corresponding material information.

[0077] In the present embodiment, before uploading the original model to the server 20, the user can configure the material information of the original model according to actual needs, and when uploading the original model to the server 20, the material information corresponding to the original model is uploaded to the server 20 for storage together.

[0078] Step S380: Determine the target association relationship corresponding to the target copy model in the server according to the second identifier of the target copy model, and obtain the attribute information of the target copy model from the target association relationship.

[0079] Optionally, the user may use the second identifier of the target copy model as a keyword to directly determine the target association relationship corresponding to the target copy model in the server 20.

[0080] In this embodiment, the association relationship can be represented as follows in the table:

[0081]

[0082] Among them, the attribute information of the copy model recorded in this association relationship includes a note attribute and a mark attribute. The note attribute of the copy model is "reference", and the mark attribute is "copy".

[0083] It should be noted that the note attribute can be set according to actual needs and is not limited in the embodiments of the present invention. For example, the note attribute can also be "refer to", "see", etc.; the mark attribute can also be set according to actual needs and is not limited in the embodiments of the present invention. For example, the mark attribute can also be "duplicate copy", etc.

[0084] Step S390, when the attribute information of the target copy model meets a preset condition, obtain the material information corresponding to the original model associated with the target copy model from the server.

[0085] Optionally, the preset condition may be that the note attribute is the first preset character and the mark attribute is the second preset character. That is to say, in the attribute information of the target copy model, the note attribute corresponds to the first preset character in the preset condition, and the mark attribute corresponds to the second preset character in the preset condition. Then, the attribute information of the target copy model meets the preset condition. At this time, obtain the material information corresponding to the original model associated with the target copy model from the server.

[0086] Exemplarily, in practical applications, when the note attribute of the target copy model is "reference" and the mark attribute is "copy", the server 20 determines the first identifier associated with the second identifier according to the target association relationship to determine the original model associated with the target copy model, and then determines the material information corresponding to the original model. The terminal device 10 can obtain the material information corresponding to the original model associated with the target copy model from the server 20.

[0087] It should be noted that the first preset character can be set according to actual needs and is not limited in the embodiments of the present invention. For example, the first preset character can also be "refer to", "see", etc.; the second preset character can also be set according to actual needs and is not limited in the embodiments of the present invention. For example, the first preset character can also be "duplicate copy", etc.

[0088] It should be noted that Figure 4 and Figure 5The execution sequence between the steps S340 - S360 shown and the steps S310 - S330 and the steps S370 - S390 is only an example. In actual applications, there may be a situation where new original models and the associated copy models for each original model are extended in the server 20. At this time, the steps S340 - S360 may be executed between any two of the steps S310 - S330 and the steps S370 - S390, or may be executed before the steps S330 and S370. This embodiment does not limit this.

[0089] In an alternative embodiment, the method for obtaining a copy model by simplifying the obtained original model includes:

[0090] Delete the confidentiality components and the components not related to the design in the original model, and perform format conversion on the original model to obtain the copy model corresponding to the original model.

[0091] Optionally, after deleting the confidentiality components and the components not related to the design in the original model, save the modified model as an intermediate format model, that is, a general format model, so that users can use this intermediate format model in different scenarios; save the intermediate format model as a single - part format model, and use this single - part format model as the copy model corresponding to the original model. Among them, the intermediate format can be STP (Segmenting, Targeting, Positioning) format, or can also be IGS (Initial Graphics Specification) format. The embodiments of the present invention do not limit this.

[0092] Optionally, after deleting the confidentiality components in the original model, when it needs to be sent to external personnel, the confidentiality of the model can be improved; the components not related to the design include internal structure components such as fasteners and components that do not affect collaborative design.

[0093] In another alternative embodiment, the method for obtaining a copy model by simplifying the obtained original model further includes:

[0094] Create an initial copy model, and import the initial copy model into the original model; activate the initial copy model; in response to the user's copy operation, copy the components selected by the user in the original model to the initial copy model to obtain the copy model corresponding to the original model.

[0095] Among them, the components selected by the user do not include the confidentiality components and the components not related to the design.
