Description

Technical Field

[0001] This invention relates to the fields of patent information visualization and new energy vehicle industry chain analysis technology, specifically to a precise matching map of the new energy vehicle industry chain and patents, and a method for drawing the map. Background Technology

[0002] The patent layout of the new energy vehicle industry is highly correlated with its supply chain segments. Accurately representing the matching relationship between these segments is a core requirement for patent applications, industry R&D, and patent analysis, and a visual map is a crucial tool for achieving this. Currently, existing new energy vehicle supply chain and patent matching maps have significant shortcomings and cannot meet the requirements of formal applications such as patent applications. First, the visual distinctions are blurred and the matching relationships are unclear. The existing publicly available "Patent Atlas of New Energy Vehicles in China" uses colored solid frames to mark both the industry chain and the patents, without clear association markers. The frame styles are completely identical, making it impossible to quickly identify the correspondence between the two and easily causing information confusion. Some atlases only use text labels for distinction, without visual layering design, resulting in extremely low information reading efficiency.

[0003] Secondly, the layout is not standardized and does not meet the standards for patent drawings. The State Intellectual Property Office has strict requirements for patent drawings, including pure black and white, reasonable spacing, no obstruction or overlap, and no text overlapping the lines. However, most existing drawings are in color, and some commercial industry chain drawings have problems such as overlapping frames, intersecting arrows, and text overlapping the lines, which cannot be directly used for patent applications and require a lot of additional modifications, increasing operating costs.

[0004] Third, the industrial chain is not clearly defined, and the matching accuracy is low. The existing map is vague in its division of the upstream, midstream, and downstream levels of the new energy vehicle industrial chain, lacks detailed technical directions, and there are no clear standards for matching patented technologies with links in the industrial chain, which easily leads to mismatches and omissions, and cannot accurately present the one-to-one correspondence between the two.

[0005] Therefore, there is an urgent need for a new energy vehicle industry chain and patent precision matching map that is visually distinct, conforms to the patent drawing standards in layout, has a clear industry chain division, and is accurately matched. At the same time, it is necessary to provide a corresponding standardized drawing method to solve the above-mentioned problems of existing maps and meet the usage needs of formal scenarios such as patent application and industry analysis. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a precise matching map and drawing method for the new energy vehicle industry chain and patents. The map adopts standardized visual design and layout to achieve accurate presentation of industry chain links and patent technologies, and fully complies with the patent drawing standards of the State Intellectual Property Office, and can be directly used for patent applications. At the same time, through a clear drawing method, the standardization and consistency of map drawing are guaranteed, solving the problems of visual blurring, non-standard layout and low matching accuracy of existing maps.

[0007] To achieve the objective of this invention, the technical solution adopted is as follows: A precise matching map of the new energy vehicle industry chain and patents is presented. This map is a pure black-and-white visual map specifically designed for patent application scenarios. The overall layout and design rules strictly adhere to the patent drawing standards of the State Intellectual Property Office. The core design features a "three-level industry chain division + double-lined frame visual differentiation + precise black arrow association," divided into three independent maps: upstream, midstream, and downstream. These maps can be used individually or in combination. The specific design is as follows: (1) Core design rules Standard format: The entire document adopts a pure black and white format with no color elements. The frame, arrows, and text are all black, and the background is white, which meets the color requirements of the patent drawings. Frame rules: The links / sub-directions of the industrial chain are represented by black solid-line rectangles, and the patented technologies are represented by black dashed-line rectangles. The line width of both solid and dashed lines is uniformly 0.2-0.3 mm. The frames of both black solid-line and black dashed-line rectangles are standard rectangles, without deformation or tilt. Arrow rules: Use black straight arrows to connect matching solid and dashed frames. The black arrows have no intersections, bends, or branches. The line width is the same as the frame. The tip of the black arrow is a standard triangle, close to the edge of the corresponding frame, with no gaps or overlaps. Text rules: All text should use the standard Song typeface, size 10-14, and be centered inside the corresponding frame. There should be no lines, no text extending beyond the frame, no blurring, and the spacing between the text and the frame should be uniform. Layout rules: The overall horizontal spacing of the diagram should be ≥1.5 cm and the vertical spacing should be ≥1 cm. All black solid line rectangles, black dashed line rectangles, and black arrows should be distributed hierarchically, without obstruction or overlap, and all elements should be evenly distributed for a clean visual appearance. (2) Industrial chain hierarchy and matching design The map is divided into three independent industry chain levels—upstream, midstream, and downstream—based on the technological processes and value distribution of the new energy vehicle industry. Each level is represented by an independent map, and the framework layout and patent matching design for each level are as follows: Upstream Core Material Matching Map: The core focuses on the new energy vehicle core material industry chain, drawing four main black solid line rectangles: cathode material, anode material, separator, and electrolyte or electrolyte solution. Under each main black solid line rectangle, a corresponding sub-black solid line rectangle for the specific technology direction is drawn (e.g., under cathode material, NCM ternary material and lithium iron phosphate sub-black solid line rectangles are drawn). Each sub-black solid line rectangle is connected to a matching patent technology black dashed line rectangle by a black arrow, covering the R&D and preparation patents in the core material field. The black arrows do not intersect. The layout of the rectangles is arranged in the manner of "main black solid line rectangles on top, sub-black solid line rectangles below, and patent black dashed line rectangles on the sides" to ensure clarity. Midstream Core Components and Manufacturing Matching Map: The core is the new energy vehicle core components and manufacturing industry chain links. It draws four main black solid line rectangles: power battery, motor, electronic control, and vehicle manufacturing. Under each main black solid line rectangle, there are sub-black solid line rectangles for the corresponding sub-technology direction (e.g., under power battery, there are sub-black solid line rectangles for square power battery and soft pack power battery). Each sub-black solid line rectangle is connected to the matching patent technology black dashed line rectangle by black arrows. It covers the patents of the entire process of core component R&D, production, and manufacturing. The layout is arranged in the manner of "main black solid line rectangles are distributed horizontally, and sub-black solid line rectangles and patent black dashed line rectangles correspond vertically", which conforms to visual habits. Downstream Application and Service Matching Map: The core is the new energy vehicle application and service industry chain links, drawing four main black solid line rectangles: operation services, charging and swapping, battery recycling, and after-sales maintenance. Under each black solid line rectangle, there are corresponding sub-black solid line rectangles for specific scenarios (e.g., under battery recycling, there are sub-black solid line rectangles for cascade utilization and material recycling). Each sub-black solid line rectangle is connected to the matching patent technology black dashed line rectangle by a black arrow, covering the entire chain of patents in application, service, and recycling. The layout is arranged in a way that the main black solid line rectangles are distributed vertically, and the sub-black solid line rectangles and patent black dashed line rectangles correspond horizontally, ensuring that the matching relationship is intuitive. (3) Characteristics of spectral files All three charts are independent PNG format visualization files, with a resolution adapted for A4 paper printing, without stretching or blurring; the file names follow standardized rules, namely " Figure 1 "_Upstream_Black and White.png" Figure 2 _Midstream_Black and White.png” Figure 3 The file name is "Downstream_Black and White.png", which is easy to identify and manage. All files do not require additional modification and can be submitted directly as patent illustrations. They can also be combined for formal scenarios such as industry analysis reports and scientific research papers.

[0008] Option 2: A method for drawing a precise matching map of the new energy vehicle industry chain and patents. Compared to the standardized drawing method for the matching map mentioned above, this method ensures the standardization, consistency, and accuracy of the map drawing through fixed steps and design standards. The drawing process requires no complex operations, and the drawing results conform to the patent drawing standards of the State Intellectual Property Office. Specifically, it includes the following steps: Step 1: Setting basic parameters for the graph First, determine the core basic parameters of the map to provide a unified standard for subsequent drawing; Format settings: Set the graphic to a pure black and white format, with a white background and all drawn elements in black; Line settings: The line width of the frame (black solid line rectangle / black dashed line rectangle) and the black arrow is uniformly set to 0.2~0.3 mm, and the dashed lines are standard equidistant dashed lines; Layout settings: Set the overall horizontal spacing of the map to ≥1.5 cm and the vertical spacing to ≥1 cm. The distribution of all elements must follow this spacing standard. Text settings: Ensure the text is in SimSun font, size 10-14, centered inside the frame, with a horizontal / vertical spacing of ≥0.1 cm between the text and the frame; Step 2: Draw the black solid line rectangles for the supply chain hierarchy. Based on the upstream, midstream, and downstream classification criteria, black solid line rectangles are drawn for each level of the industrial chain, divided into main black solid line rectangles and sub-black solid line rectangles. Determine the number and name of the main black solid line rectangles according to the hierarchy, and draw the main black solid line rectangles in the corresponding positions on the canvas. The frames of the black solid line rectangles are evenly distributed horizontally / vertically, and the spacing conforms to the layout standards. Below / to the right of each main black solid line rectangle, draw sub-black solid line rectangles corresponding to the sub-technical direction. The distance between the body of the sub-black solid line rectangle and the body of the main black solid line rectangle is ≥0.5 cm. All sub-black solid line rectangles have no occlusion and no overlap. The corresponding industry chain segment / sub-section name should be marked in the center inside the main black solid line rectangle and the sub-black solid line rectangle. The text should conform to the text setting standard, without overlapping the lines or exceeding the frame. Step 3: Patented technology for matching and drawing black dashed rectangles Based on the precise matching results between patented technologies and the subdivided technology directions of the industry chain, draw a black dashed rectangle around the patented technology; Matching principles are determined as follows: when the patented technology and the sub-sector of the industry chain meet one of the following conditions: technical feature similarity ≥ 80%, application scenario consistency, and matching technology classification number, it is considered a precise match; Draw a black dashed rectangle next to the corresponding sub-black solid rectangle (left / right / bottom). The spacing between the black dashed rectangle and the sub-black solid rectangle should conform to the layout standard, with no obstruction or overlap. The name of the matching patent technology is marked in the center inside the black dashed rectangle. The text conforms to the text setting standard and ensures that it is the same size as the text in the black solid rectangle. Step 4: Match and draw associated black arrows A black arrow connects the precisely matched sub-black solid-line rectangles to the black dashed-line rectangles, providing a clear visual representation of the matching relationship: Starting from the edge of the solid black rectangle in the industrial chain, draw a straight black arrow. The other end of the black arrow points to the edge of the corresponding dashed black rectangle in the patent technology, ensuring that the black arrows do not cross, bend, or branch. Adjust the position of the black arrow so that the tip of the black arrow is close to the edge of the frame without gaps or overlaps, the width of the black arrow line is the same as that of the frame, and the tip of the black arrow is a standard triangle, the size of which is adapted to the frame. When the same black solid line rectangle matches multiple patented technologies, the arrows are distributed at even intervals, without intersection or overlap; Step 5: Standardized Validation and File Export After the drawing is completed, the atlas is standardized and verified in all dimensions to ensure that it conforms to the patent drawing standards, and then the standardized file is exported: Standard verification: Check whether the spectrum is a pure black and white standard, without any color elements; Design verification: Check whether the frame of the black solid line rectangle or the black dashed line rectangle, the black arrow, and the text conform to the design rules of this invention, and whether the line width, font, and spacing are consistent. Layout validation: Check that all elements are unobstructed and unoverlapping, that the left and right / vertical spacing meets the layout standards, and that the black arrows do not intersect. Patent drawing verification: Check whether the drawing meets all the requirements of the State Intellectual Property Office for patent drawings. If the verification fails, adjust the position of the frame, spacing or text size until it meets the specifications. File Export: After verification, name each map according to the rule "map X_XX stage_black and white.png" and export it as a PNG file with a resolution adapted for A4 paper printing to complete the map drawing.

[0009] The beneficial effects of this invention are as follows: Clear visual distinction and accurate matching relationship: This invention adopts the design rule of "solid line boxes marking the industrial chain and dashed line boxes marking the patent technology", combined with black arrows to accurately indicate the matching relationship, so that the correspondence between the two can be identified at a glance, solving the problems of visual blur and information confusion in existing maps.

[0010] The layout is standardized and can be directly used for patent applications: The diagrams of this invention are in pure black and white format, and all design rules and layout standards strictly follow the requirements of the State Intellectual Property Office for patent drawings. There is no obstruction, no overlap, and no text overlapping. It can be submitted directly as a patent drawing without additional modifications, which greatly reduces the operating cost and time cost.

[0011] The industrial chain is clearly divided and covers the entire industry dimension: This invention clearly divides the new energy vehicle industrial chain into upstream, midstream and downstream, covering all aspects and subdivided technical directions of core materials, core components and manufacturing, application and services, and fully presents the patent layout and industrial chain matching relationship of the new energy vehicle industry.

[0012] The drawing method is standardized and the results are highly consistent: The drawing method provided by this invention ensures the standardization and consistency of the drawing through fixed basic parameters, drawing steps and verification standards. The drawings drawn by different people according to this method all meet the design requirements and are suitable for large-scale drawing and promotion.

[0013] Highly adaptable and widely applicable: The atlas of this invention is divided into three independent files, which can be used individually or in combination. It can be used directly for patent applications, and can also be widely applied to formal scenarios such as patent analysis, industrial research and development, investment decision-making, and scientific research papers in the field of new energy vehicles, thus having high practical value. Attached Figure Description

[0014] Figure 1 This is a map showing the precise matching of the upstream core materials industry chain and patents for new energy vehicles. The solid black boxes in the map represent the various links and sub-technical directions of the upstream core materials, while the dashed black boxes represent the patent technologies that are precisely matched with each sub-direction. The black arrows indicate the precise matching relationship between the two. All elements are unobstructed and non-overlapping, and the text is not superimposed on any lines. Figure 2 This is a map showing the precise matching of patents with the core components and manufacturing industry chain in the midstream of new energy vehicles. The black solid boxes in the map represent the various links and sub-technical directions of the core components and manufacturing in the midstream, while the black dashed boxes represent the patent technologies that are precisely matched with each sub-direction. The black arrows do not intersect and precisely indicate the matching relationships. The layout is even and clear. Figure 3 This diagram shows the precise matching of patents with the downstream application and service industry chain of new energy vehicles. The solid black boxes represent the various links and sub-scenarios of downstream applications and services, while the dashed black boxes represent the patent technologies that are precisely matched with each sub-scenarios. The black arrows are close to the boxes without any gaps, making the matching relationship intuitively clear. Detailed Implementation

[0015] The present invention will be further described and illustrated below with reference to specific embodiments.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0017] In the description of this invention, it should be understood that the terms "upper", "lower", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship of the technical solution, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0018] like Figure 1-3 As shown, a precise matching map of the new energy vehicle industry chain and patents is presented. The map is a pure black-and-white visual map, dividing the new energy vehicle industry chain into upstream, midstream, and downstream levels. It employs a core design rule of "solid lines + dashed lines + black arrows" to achieve a precise matching of new energy vehicle industry chain links with patent technologies. The overall layout conforms to the patent drawing standards of the State Intellectual Property Office. Specific design features include: (1) Industry chain hierarchy: The upstream industry chain hierarchy includes core material links such as positive electrode material, negative electrode material, separator, electrolyte or electrolyte, battery cell, drive motor, electronic control chip, BMS module, and charging pile; the midstream industry chain hierarchy includes core components and manufacturing links such as power battery, electric drive axle, vehicle electronic control, intelligent cockpit domain control, autonomous driving domain control, vehicle manufacturing, and 800V high voltage platform; the downstream industry chain hierarchy includes application and service links such as new energy vehicle operation charging or battery swapping services, battery recycling, and aftermarket maintenance. Each link includes corresponding sub-technical directions. (2) Visual differentiation design: each link and subdivided technology direction in the industrial chain is marked with a black solid line rectangle, and the patented technology that is precisely matched with each link is marked with a black dashed line rectangle. The black solid line rectangle and the black dashed line rectangle are matched with the size of the map layout, and the two form a clear visual distinction. (3) Matching and association design: black arrows without intersection or curvature are used to connect the black solid line rectangles of the industrial chain level with the corresponding black dashed line rectangles of the patent. One end of the black arrow points to the subdivided technology direction of the industrial chain level, and the other end points to the matching patent technology, accurately indicating the one-to-one correspondence between the two. (4) Standardized layout design: The horizontal spacing of the map is ≥1.5 cm and the vertical spacing is ≥1 cm. All black solid line rectangles, black dashed line rectangles and black arrows are unobstructed and unoverlapping. The text labels in the map are unlined and unblurred. The font and frame size are matched. The overall layout is uniform and clear.

[0019] like Figure 1 As shown, a precise matching map of the new energy vehicle industry chain and patents is presented. In the upstream industry chain, the black solid rectangles representing the core material links include sub-black solid rectangles representing sub-technical directions such as NCM ternary materials, lithium iron phosphate, carbon-based or silicon-based anodes, lithium hexafluorophosphate, wet-process separator substrates, electrolyte raw materials, power battery cells, permanent magnet drive motors or asynchronous drive motors, SiC electronic control chips or IGBT electronic control chips, BMS modules, and charging pile components. Each sub-black solid rectangle represents a specific technology direction and is precisely matched with the corresponding black dashed rectangle representing a patent technology by a black arrow, covering all technical directions of core materials for new energy vehicles.

[0020] like Figure 2 As shown, a precise matching map of the new energy vehicle industry chain and patents is presented. In the midstream industry chain, the black solid-line rectangles representing core components and manufacturing links include sub-technology sub-categories such as CTP square power battery packs or CTC square power battery packs, three-in-one electric drive axles, permanent magnet drive motors or asynchronous drive motors, vehicle electronic control units (ECUs), intelligent cockpit domain control, autonomous driving domain control, pure electric vehicle platforms, hydrogen fuel cell vehicle platforms, plug-in hybrid vehicle platforms or range-extended vehicle platforms, integrated casting lightweight vehicle platforms, and 800V high-voltage platforms. The black dashed-line rectangles matching the black solid-line rectangles of each sub-technology sub-categories cover patents throughout the entire process of R&D, manufacturing, and production. The black arrows do not intersect.

[0021] like Figure 3 As shown, a precise matching map of the new energy vehicle industry chain and patents is presented. In the downstream industry chain, the black solid rectangles representing the application and service links include private car applications, commercial vehicle applications or ride-hailing applications, new energy logistics vehicle applications, new energy bus applications, fast charging station or supercharging station operation and service, battery swapping services, power battery recycling and cascade utilization, vehicle OTA upgrades, auto finance or maintenance, new energy vehicle repair, and used car appraisal sub-black solid rectangles. Each sub-black solid rectangle is matched with the corresponding black dashed rectangle of the patent technology, covering the entire patent chain of new energy vehicle applications, services, and recycling.

[0022] Furthermore, the text annotations within the atlas use the standardized Song typeface, with a font size of 10-14. The text is centered within the corresponding black solid-line rectangle or black dashed-line rectangle, without overlapping the lines or extending beyond the frame, ensuring both text legibility and the neatness of the atlas.

[0023] Furthermore, the line width of the black solid line rectangle or the black dashed line rectangle is 0.2 to 0.3 mm, the line width of the black arrow is the same as that of the frame, the black arrow is a standard triangular arrow, and the tip of the black arrow is close to the edge of the corresponding frame.

[0024] Furthermore, the map can be divided into three independent maps: upstream core material matching map, midstream core component and manufacturing matching map, and downstream application and service matching map. They can also be combined into a single full-industry chain matching map. Each map is an independent PNG format file, and the file naming rule is "map X_XX link_black and white.png". No additional modifications are required before submission.

[0025] like Figure 1-3 As shown, a method for drawing a precise matching map of the new energy vehicle industry chain and patents is used to draw the above map, including the following steps: Step 1: Basic settings for the atlas. Determine that the atlas is in pure black and white format. Set the line width of the black solid line rectangle or black dashed line rectangle to 0.2-0.3 mm. Set the line width of the black arrows to be the same as the frame. Set the layout standard of left and right spacing ≥ 1.5 cm and vertical spacing ≥ 1 cm. Determine that the text is in Song typeface, size 10-14, and the text is centered. Step 2: Draw the industry chain hierarchy. Divide the new energy vehicle industry chain into upstream, midstream and downstream. Draw black solid line rectangles in the corresponding positions of the map and label the name of each link. Draw black solid line rectangles for subdivided technical directions below or to the right of each link and label the name of the subdivided direction. Ensure that all black solid line rectangles are unobstructed and do not overlap. Step 3: Patent technology matching and drawing. Draw a black dashed rectangle next to the black solid rectangle in the corresponding sub-technical direction of the industry chain, and label the name of the matching patent technology. The spacing between the black dashed rectangle and the corresponding black solid rectangle should meet the layout standard, with no obstruction or overlap. Step 4: Matching and drawing: Use black arrows to connect the black solid line rectangles of the industrial chain sub-items with the corresponding black dashed line rectangles of the patents, ensuring that the black arrows do not cross or bend, and that the tips are close to the edges of the frames to accurately indicate the matching relationship; Step 5: Standardization verification. Verify whether the atlas is in pure black and white format, whether the frame of the black solid line rectangle or the black dashed line rectangle, whether the black arrows and text conform to the design rules, and whether the overall layout is free of obstruction and overlap. After verification, name it "Figure X_XX Step_Black and White.png" and export it as a PNG format file to complete the atlas drawing.

[0026] Furthermore, the matching principle between the patented technology and the subdivided technology direction of the industrial chain in step 3 is as follows: the technical feature similarity must be ≥80% at the same time, and the application scenario must be consistent and the technical classification number must match. If either of these conditions is met, it is determined to be an accurate match and the corresponding black dashed rectangle is drawn.

[0027] Furthermore, in step 5, the standardization verification must simultaneously meet all the requirements of the patent drawings of the State Intellectual Property Office. If the verification fails, adjust the position of the frame, the spacing, or the size of the text until it meets the requirements.

[0028] The new energy vehicle industry chain and patent precise matching map of this invention can be drawn using computer graphics software (such as Visio, AI, PS) or automatically drawn using Python programming. The graphics software needs to support pure black and white output, precise drawing of frames / arrows and spacing adjustment. Programmatic drawing can be implemented based on Matplotlib and NetworkX libraries. The following are two specific embodiments: Example 1: Atlas plotting based on Visio software: This embodiment uses Visio 2019 software to draw a precise matching map of the new energy vehicle industry chain and patents. The specific steps are as follows: Basic parameter settings: Open Visio software, create a new blank drawing page, set the page size to A4 paper size, and the background to white; set the line width to 0.2 mm, solid lines to standard straight lines, and dashed lines to equidistant dashed lines; set the text to SimSun font, size 10, and center-aligned. Upstream Mapping: Draw four main black solid-line rectangles on the drawing page, labeled "Positive Electrode Material, Negative Electrode Material, Separator, Electrolyte or Electrolyte," evenly distributed horizontally with a spacing of 2 cm. Under each main black solid-line rectangle, draw sub-black solid-line rectangles for specific technical directions (e.g., under positive electrode material, draw sub-rectangles for NCM ternary material and lithium iron phosphate), with a spacing of 0.5 cm between the sub-rectangles and the main black solid-line rectangles. Based on the matching results, draw black dashed rectangles for patented technologies to the right of the sub-rectangles, spaced 1.5 cm apart, and label them with the patent name. Connect the sub-rectangles with the corresponding black dashed rectangles using black arrows, with no intersections and the tips close to the frame. Midstream / Downstream Mapping: Following the method for drawing the upstream map, midstream and downstream maps are drawn separately. The main black solid rectangle in the midstream represents "power battery, motor, electronic control, and vehicle manufacturing", and the main black solid rectangle in the downstream represents "operation services, charging and battery swapping, battery recycling, and aftermarket maintenance". The layout and design rules are strictly followed. Standardization verification: Check whether the three diagrams are in pure black and white format, whether the black solid line rectangles or black dashed line rectangles, black arrows, and text conform to the design rules, and whether all elements are unobstructed and unoverlapping; scale the diagrams to the A4 paper size and check that the text is not crooked and the arrows are not intersecting. File export: Export each map by " Figure 1 "_Upstream_Black and White.png" Figure 2 _Midstream_Black and White.png” Figure 3 Name the file "_Downstream_Black and White.png", export it as a PNG file with a resolution of 300 dpi, and the drawing is complete.

[0029] Example 2: Automated Atlas Drawing Based on Python Programming This embodiment uses Python, combined with the Matplotlib and NetworkX libraries, to automate the plotting of the graph. The specific steps are as follows: Environment setup: Configure a Python 3.8+ environment, install Matplotlib and NetworkX libraries, and set the plotting backend to support PNG output format.

[0030] Basic parameter definition: Write code to define basic parameters, set the line width to 0.3mm, the black solid line rectangle to plt.Rectangle, the black dashed line rectangle to plt.Rectangle (linestyle='--'), the black arrow to plt.arrow, the text to fontsize=12, fontfamily='SimSun' (SimSun), and set the left and right spacing to 2 cm and the vertical spacing to 1.5 cm; Importing Industry Chain and Patent Data: Importing structured data on upstream, midstream, and downstream links of the new energy vehicle industry chain, sub-directions, and matching patent technologies. The data includes link names, sub-directions, patent names, and matching relationships. Automated drawing: Write loop code to draw the main black solid line rectangle, sub black solid line rectangle, and patent black dashed line rectangle in sequence according to the data. Use coordinate positioning to ensure that the spacing meets the standard, and that there is no occlusion or overlap. Write code to draw black arrows and connect the matching sub black solid line rectangles and patent black dashed line rectangles to ensure that the black arrows do not intersect. Standardized verification and export: Write code to verify the coordinates and spacing of each element to ensure compliance with design rules; after verification, export the three maps as PNG files according to standardized naming rules, save them to the specified path, and complete the automated drawing.

[0031] This invention adopts the design rule of "solid line boxes marking the industrial chain and dashed line boxes marking the patented technology", combined with black arrows to accurately indicate the matching relationship, so that the correspondence between the two can be identified at a glance, solving the problems of visual blurring and information confusion in existing maps.

[0032] The diagrams of this invention are in pure black and white format. All design rules and layout standards strictly follow the requirements of the State Intellectual Property Office for patent drawings. There is no obstruction, no overlap, and no text overlapping. They can be submitted directly as patent drawings without additional modifications, which greatly reduces operating costs and time costs.

[0033] This invention clearly divides the new energy vehicle industry chain into upstream, midstream, and downstream segments, covering all aspects and subdivided technical directions, including core materials, core components and manufacturing, applications and services, and fully presents the patent layout and matching relationship of the new energy vehicle industry chain.

[0034] The drawing method provided by this invention ensures the standardization and consistency of atlas drawing through fixed basic parameters, drawing steps and verification standards. Atlases drawn by different people according to this method all meet the design requirements and are suitable for large-scale drawing and promotion.

[0035] The atlas of this invention is divided into three independent files, which can be used individually or in combination. It can be used directly for patent applications, and can also be widely applied to formal scenarios such as patent analysis, industrial research and development, investment decisions, and scientific research papers in the field of new energy vehicles, thus having high practical value.

Specific embodiments have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only for helping to understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.

The precise matching map of the new energy vehicle industry chain and patents according to any one of claims 1 to 6, characterized in that, The map can be divided into three independent maps: upstream core material matching map, midstream core component and manufacturing matching map, and downstream application and service matching map. They can also be combined into a single full-industry chain matching map. Each map is an independent PNG format file, and the file naming rule is "map X_XX link_black and white.png". No additional modifications are required before submission.

8. A method for drawing a precise matching map of the new energy vehicle industry chain and patents, characterized in that, To draw the spectrum according to any one of claims 1 to 7, the following steps are included: Step 1: Basic settings for the atlas. Determine that the atlas is in pure black and white format. Set the line width of the black solid line rectangle or black dashed line rectangle to 0.2-0.3 mm. Set the line width of the black arrows to be the same as the frame. Set the layout standard of left and right spacing ≥ 1.5 cm and vertical spacing ≥ 1 cm. Determine that the text is in Song typeface, size 10-14, and the text is centered. Step 2: Draw the industry chain hierarchy. Divide the new energy vehicle industry chain into upstream, midstream and downstream. Draw black solid line rectangles in the corresponding positions of the map and label the name of each link. Draw black solid line rectangles for subdivided technical directions below or to the right of each link and label the name of the subdivided direction. Ensure that all black solid line rectangles are unobstructed and do not overlap. Step 3: Patent technology matching and drawing. Draw a black dashed rectangle next to the black solid rectangle in the corresponding sub-technical direction of the industry chain, and label the name of the matching patent technology. The spacing between the black dashed rectangle and the corresponding black solid rectangle should meet the layout standard, with no obstruction or overlap. Step 4: Matching and drawing: Use black arrows to connect the black solid line rectangles of the industrial chain sub-items with the corresponding black dashed line rectangles of the patents, ensuring that the black arrows do not cross or bend, and that the tips are close to the edges of the frames to accurately indicate the matching relationship; Step 5: Standardization verification. Verify whether the atlas is in pure black and white format, whether the frame of the black solid line rectangle or the black dashed line rectangle, whether the black arrows and text conform to the design rules, and whether the overall layout is free of obstruction and overlap. After verification, name it "Figure X_XX Step_Black and White.png" and export it as a PNG format file to complete the atlas drawing.

9. The drawing method according to claim 8, characterized in that, The matching principle between the patented technology and the subdivided technology direction of the industry chain in step 3 is as follows: the similarity of technical features must be ≥80% at the same time, and the application scenarios must be consistent and the technical classification numbers must match. If either of these conditions is met, it is determined to be an exact match and the corresponding black dashed rectangle is drawn.

10. The drawing method according to claim 8, characterized in that, The standardization verification described in step 5 must simultaneously meet all the requirements of the patent drawings of the State Intellectual Property Office. If the verification fails, adjust the position of the frame, the spacing, or the text size until it meets the requirements.
