Description

Technical Field

[0001] The present invention belongs to the technical field of chassis manufacturing, and in particular relates to a chassis structure and a chassis design method driven by UG expressions. Background Art

[0002] 19-inch (19in) chassis designs adhere to specific industry standards to ensure compatibility with a wide range of cabinets. These chassis come in a variety of sizes, all subject to certain height restrictions. When chassis that perform the same function need to meet different height restrictions, the chassis components must be redesigned and assembled accordingly based on the size and requirements of the different cabinets. This repetitive design and assembly work not only increases workload but can also impact production and cost efficiency.

[0003] Patent application document with publication number CN115933836A discloses a new 19-inch direct air-cooled heat dissipation chassis, which enhances its heat dissipation function through structural optimization.

[0004] The patent application document with publication number CN115373487A discloses a 19-inch rack-mounted heat dissipation chassis suitable for 6U boards. The chassis allows cold air to enter from the front panel, pass through the heat-concentrating board I and power module, and then the hot air is discharged from the rear panel, which is a front-in and rear-out form.

[0005] However, the technical problems of improving the efficiency of 19-inch chassis design and ensuring design accuracy have not been solved. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a chassis structure and a chassis design method driven by UG expressions.

[0007] The present invention is achieved through the following technical solutions.

[0008] The present invention provides a chassis structure, including an upper cover, a rear panel, a right side panel, a left side panel, a front panel and a bottom panel, wherein the two ends of one side surface of the front panel are respectively connected to one end of the right side panel and the left side panel, and the other ends of the right side panel and the left side panel are respectively connected to the two ends of one side surface of the rear panel to form a frame structure, wherein the top of the frame structure is connected to the upper cover, and the bottom of the frame structure is connected to the bottom panel.

[0009] Preferably, a first groove and a second groove are provided on the front panel, and the first groove is provided on one side of the second groove.

[0010] Preferably, a first mounting hole is provided on the first groove.

[0011] Preferably, second mounting holes are provided on both sides of the front panel.

[0012] Preferably, third mounting holes are respectively provided on both sides of the upper cover plate, the rear panel, the right side panel and the left side panel.

[0013] Preferably, a handle is provided on the front panel.

[0014] A chassis design method based on UG expression drive includes establishing an expression model of the chassis shell in the 3D design environment of UG 3D modeling software, and generating 19-inch chassis of different sizes and structures by modifying expression parameters.

[0015] A chassis design method based on UG expression drive includes the following steps:

[0016] A1: Set the height expression of the front panel, and link the heights of the rear panel, right panel, and left panel to the height expression of the front panel through expressions;

[0017] A2: Set the length expression of the bottom plate, and link the lengths of the rear panel, right panel, and left panel to the length expression of the bottom plate through expressions;

[0018] A3: When the height of the front panel needs to be changed, the length of the base plate remains unchanged. By changing the height expression of the front panel, the overall height of the chassis moves along the Z-axis to follow the change in the height of the front panel.

[0019] When the depth of the chassis needs to be changed, the height of the front panel remains unchanged. Changing the length of the bottom plate in the expression can move the depth of the chassis along the Y-axis.

[0020] Preferably, the step of setting the front panel height expression includes: limiting the front panel width to a fixed value, the front panel height expression is N*U-0.8, where N can be 1, 2, 3...n, U is the height level value of the front panel, and the front panel height can be divided into 1U, 2U, 3U...nU.

[0021] Preferably, the length of the base plate is expressed as: 350+50*a, where a can be -1, 0, 1, 2, 3...n.

[0022] The beneficial effects of the present invention are:

[0023] 1. Improved design flexibility and response speed

[0024] The method of the present invention allows designers to quickly adjust the size and shape of the chassis to accommodate varying dimensional requirements using pre-set parameters and formulas. This method accelerates the design process and allows for the rapid generation of multiple design solutions for comparison and optimization without sacrificing quality.

[0025] 2. Design consistency and standardization are guaranteed

[0026] Formula-based parametric design ensures that every component of the chassis design adheres to consistent design standards and specifications. This consistency is crucial for maintaining a consistent look and feel across the product line while also streamlining production and quality control. Standardized design also helps reduce material waste and improve production efficiency.

[0027] 3. Error reduction and quality improvement

[0028] Formula-based parametric design reduces errors that can occur in manual drawing and sizing. All design changes are based on precise formula parameters. This accuracy improves design quality, ensures the reliability and durability of the chassis, and reduces rework and scrap.

[0029] 4. Cost control and market adaptability

[0030] Because material usage and manufacturing processes are directly linked to parameters, parametric design allows designers to predict and control manufacturing costs during the design phase. This increased cost control capability helps optimize designs at an early stage to meet budget constraints. Parametric design also enables chassis designs to quickly adapt to market changes, such as the use of new materials or technologies, thereby maintaining product competitiveness.

[0036] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0037] Example:

[0038] like Figures 1 to 4As shown, a chassis structure includes an upper cover 1, a rear panel 2, a right side panel 3, a left side panel 4, a front panel 5 and a bottom panel 6, the two ends of one side of the front panel 5 are respectively connected to one end of the right side panel 3 and the left side panel 4, the other ends of the right side panel 3 and the left side panel 4 are respectively connected to the two ends of one side of the rear panel 2 to form a frame structure, the top of the frame structure is connected to the upper cover 1, and the bottom of the frame structure is connected to the bottom panel 6.

[0039] The front panel 5 is provided with a first groove 51 and a second groove 52 , wherein the first groove 51 is provided on one side of the second groove 52 .

[0040] The first groove 51 is provided with a first mounting hole 53. The sealing strip can be installed in the first groove 51 and the second groove 52, and the sealing strip is fastened to the chassis by connecting the first mounting hole 53 with bolts.

[0041] Second mounting holes 54 are provided on both sides of the front panel 5 . When the chassis is embedded, bolts are passed through the second mounting holes 54 to fasten the chassis to the embedded body.

[0042] Third mounting holes 8 are respectively provided on both sides of the upper cover plate 1 , the rear panel 2 , the right side panel 3 and the left side panel 4 for assembling the chassis by using bolts.

[0043] A handle 7 is provided on the front panel 5 .

[0044] A chassis design method based on UG expression drive includes establishing an expression model of the chassis shell in the 3D design environment of UG 3D modeling software, and generating 19-inch chassis of different sizes and structures by modifying expression parameters.

[0045] A chassis design method based on UG expression drive includes the following steps:

[0046] A1: Set the height expression of the front panel 5, and link the heights of the rear panel 2, right panel 3, and left panel 4 to the height expression of the front panel 5 through expressions;

[0047] A2: Set the length expression of bottom plate 6, and link the lengths of rear panel 2, right panel 3, and left panel 4 to the length expression of bottom plate 6 through expressions;

[0048] A3: When the height of the front panel 5 needs to be changed, the width of the front panel 5 of a 19-inch chassis is usually limited to 482.6 mm. The length of the bottom plate 6 remains unchanged. By changing the N value in the expression for the height of the front panel 5, the overall height of the chassis moves along the Z-axis, that is, along the S2 direction, following the change in the height of the front panel 5. This allows the chassis dimensional parameter structure specified in the 19-inch chassis design specification to be quickly obtained, allowing the 19-inch chassis shell to be quickly generated, improving the design efficiency of design engineers.

[0049] When the depth of the chassis needs to be changed, that is, the length of the base plate 6 is changed, and the height of the front panel 5 remains unchanged, changing the value of a in the length expression of the base plate 6 can make the depth of the chassis move along the Y-axis direction, that is, move along the S1 direction, and then the chassis size parameter structure specified by the 19-inch chassis design specification can be quickly obtained, and the 19-inch chassis shell can be quickly generated. In order to adapt to the specified cabinet front panel size, the 19-inch chassis structure only needs to change the parameter value of the height of the front panel 5 or the length of the base plate 6 in the chassis expression model when designing a 19-inch chassis, which can drive the entire chassis model to work together as a whole, thereby achieving the effect of quickly designing a 19-inch chassis.

[0050] The step of setting the height expression of the front panel 5 includes: limiting the width of the front panel 5 to a fixed value, the height expression of the front panel 5 is N*U-0.8, where N can be 1, 2, 3...n, U is the height level value of the front panel 5, 1U=44.45mm, and the height of the front panel 5 can be divided into 1U, 2U, 3U...nU.

[0051] The length of the bottom plate 6 is expressed as: 350+50*a, where a can be -1, 0, 1, 2, 3...n.
