[0040] The following is combined with Figure 1-10 The method for establishing a skeleton model using the sketching module in the CREO software proposed in the present invention is further described in detail in the following embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in a very simplified form and are not to exact scale, and are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention. In order to make the purposes, features, and advantages of the present invention more clearly understood, please refer to the accompanying drawings.

[0041] In view of the problems that the skeleton model creation method of the skeleton model module in the existing CREO software is relatively complicated, which increases the design difficulty for ordinary designers and consumes a lot of computing resources.

[0042] On the one hand, reference Figure 1 As shown, this embodiment provides a method for establishing a skeleton model using a sketching module in CREO software, comprising the following steps:

[0043] Step S1: Obtain the appearance style data of the model to be drawn, and obtain the appearance style data from the design department of the model to be drawn. After the design department determines the style design, the style data is fixed and cannot be modified by the structural designer.

[0044] Step S2: Create a PRT file in CREO software. The PRT file created in this embodiment is a common PRT file in CREO software. The PRT file is used as a skeleton model replacement file of the model to be drawn.

[0045] Step S3: In the sketching module of the PRT file, the appearance contour surface group of the model to be drawn is obtained by externally copying geometry, specifically comprising: according to the appearance style data of the model to be drawn, the appearance contour surface group of the model to be drawn is obtained by externally copying geometry.

[0046] Step S4: importing the appearance contour surface group into the skeleton model replacement file to establish the skeleton model.

[0047] The importing of the appearance contour surface group into the skeleton model replacement file specifically includes: establishing the constraint mode and relationship corresponding to each component in the model to be drawn according to the appearance contour surface group, so as to adjust the shape and movement relationship of the model to be drawn in the sketching module.

[0048] Establishing the constraint methods corresponding to the components in the model to be drawn includes: establishing, in the sketching module, the constraint methods corresponding to the constraint relationships between the components in the model to be drawn, based on the constraint relationships between the components in the model to be drawn. The constraint methods include: one or any combination of vertical, dimensional, revolute, and linear.

[0049] Establishing the relationship equations corresponding to the components in the model to be drawn includes: establishing the relationship equations corresponding to the movement relationships between the components in the model to be drawn in a one-to-one manner using a programming language in the sketching module according to the movement relationships between the components in the model to be drawn.

[0050] Step S4.1: Based on the skeleton model established in the sketching module, checking the interference of each component in the model to be drawn, specifically including: checking the interference of each component in the model to be drawn in the sketching module based on the matching relationship between the components in the model to be drawn. After the assembly is assembled, the skeleton model established in the sketching module is used to perform interference detection on the moving parts within the entire motion trajectory.

[0051] On the other hand, this embodiment further provides an air conditioner, wherein the model of at least one component of the air conditioner is drawn using the method of establishing a skeleton model using the sketching module in the above-mentioned CREO software.

[0052] The following uses the modeling of the sliding panel of an air conditioner cabinet as an example to specifically introduce the method of using the sketching module in the above-mentioned CREO software to establish a skeleton model:

[0053] Obtain the appearance style data of the cabinet sliding panel model of the air conditioner, and obtain the appearance style data from the design department of the cabinet sliding panel model of the air conditioner. After the design department determines the style design, the style data of the cabinet sliding panel of the air conditioner is fixed, and the structural design personnel cannot modify the style data. Create a PRT file in the CREO software. The PRT file created in this embodiment is an ordinary PRT file in the CREO software. Use the PRT file as the skeleton model replacement file of the cabinet sliding panel model of the air conditioner. In the sketching module of the PRT file, the appearance contour surface group of the cabinet sliding panel model of the air conditioner is obtained by externally copying the geometry, specifically including: according to the appearance style data of the model to be drawn, the appearance contour surface group of the model to be drawn is obtained by externally copying the geometry. Import the appearance contour surface group into the skeleton model replacement file to realize the establishment of the skeleton model.

[0054] The cabinet sliding panel model of the air conditioner is a three-rail design. Figure 9 and Figure 10 As shown, the cabinet sliding panel 1 includes: a track base 4, which is used to install the guide rail and the motor and is the base of the entire cabinet sliding panel mechanism; a lower guide rail 7, which is installed on the track base 4; a sliding block 6, which is connected to the lower guide rail, and the sliding block 6 moves up and down in the specified track of the lower guide rail 7, and a straight rack is provided on the sliding block 6; a gear, which is driven by a synchronous motor, and the gear is engaged with the rack (refer to Figure 9The gear and rack structure 5) provides driving force for the cabinet sliding panel; the lifting panel 2, both sides of which are set in the upper guide rail 1; the triangular guide shaft 3, which is a key component for connecting the lifting panel 2 and the sliding block, realizes the transformation of the motion trajectory through the triangular guide shaft 3, making it possible to hide the panel. When the lifting panel 2 is lowered, it is hidden inside the unit. When it is raised, it can return to its original position to cover the gap of the air conditioner. Among them, reference Figure 10 As shown in the figure, the lower guide rail 7 and the rear guide rail 8 are two grooves on the same part. Use the above method to create the outline of the upper guide rail 1, the lower guide rail 7, and the rear guide rail 8. Take one of the upper guide rails as an example, you can see the guide rail groove of the final entity data in the CREO software (reference Figure 3 As shown), it is the sketch line drawn from the skeleton model (reference Figure 2 shown).

[0055] Using the sketching module to create a skeleton model, you can draw the model in a step-by-step, multi-feature manner. For example, the front process can complete the track laying first, and then install the sliding pulley in the back process. The back feature can borrow the shape of the front feature to create a moving track. In this way, even the most common sketching module can achieve the effect of motion simulation in the skeleton model, and can also realize the simulation of more complex shapes. Figure 4 As shown, the trajectory line created by the previous feature is yellow, and the current process is blue. When constructing the blue line, the yellow line can be used as a reference.

[0056] The lifting panel 2 is fixed using the "vertical" and "size" in the CREO software. The lifting panel 2 and the triangular guide rail axis 3 are constrained using the "rotational pair". The main axis of the triangular guide rail axis 3 and the lower guide rail 7 are constrained using the "online" constraint method and are given a starting point.

[0057] refer to Figure 5 The interface is drawn in the CREO software shown, and the movement of the sliding panel is realized by inputting the relationship formula using a simple programming language:

[0058] d270 is the dimension name for the starting point. Editing d270 adjusts the position of delta guide axis 3. If the initial position is within 1°, assign x a value of 0. If the actual position is above 360°, assign x a value of 1. The goal is to maintain a range of motion between 0 and 360°. The actual product's maximum range of motion is 370°, so consider the margin and set it to 360°.

[0059] After the initial judgment and value assignment are complete, the second judgment is performed: If x is assigned a value of 0, it indicates that lift panel 2 is still at the top, in the descending channel. Therefore, each position update moves downward by 2mm, i.e., d270 + 2. The descent speed can be adjusted as needed. As the sliding panel continues to descend, when it reaches a certain point and x is assigned a value of 1, lift panel 2 has reached the set position and needs to reverse and return to the ascending channel. This completes the creation of the air conditioner cabinet sliding panel skeleton model.

[0060] After the skeleton model and single product model of the air conditioner cabinet sliding panel are created, the single product model is assembled. Since it is a top-down design, the relative position relationship of each component is very clear. All position coordination relationships can be directly transplanted from the skeleton model of the sketching module, making the assembly efficient, reliable, and low-error.

[0061] This embodiment also provides an interference detection method for component modeling of an air conditioner, wherein the skeleton model of the air conditioner component is obtained using the above method, including: obtaining appearance style data of the air conditioner component model; creating a PRT file in CREO software as a skeleton model substitute file of the air conditioner component model; in a sketching module of the PRT file, obtaining an appearance contour surface group of the air conditioner component model by externally copying geometry; importing the appearance contour surface group into the skeleton model substitute file, and establishing corresponding constraints and relationships in the air conditioner component model based on the appearance contour surface group to adjust the shape and motion relationship of the air conditioner component model in the sketching module, thereby realizing the establishment of the skeleton model of the air conditioner component model using the sketching module; after the skeleton model of the air conditioner component model is established using the sketching module, determining a number of mating parts in the air conditioner component model that require interference detection, finding a line corresponding to each mating part in the skeleton model of the sketching module, and realizing interference detection by performing gap measurement or motion trajectory simulation in the sketching module.

[0062] Since there are many mating parts in the component model of the air conditioner, the following are examples of interference detection of several of them for illustration: After assembly, the cabinet sliding panel skeleton model established by the sketching module is used to perform interference detection on the moving parts within the entire motion trajectory.

[0063] Example 1: To detect the starting point position, it is necessary to review the fitting clearance between the bottom of the lifting panel 2 and the front panel 9 (the front panel 9 is located below the lifting panel 2). The theoretical design value is 2mm. This gap is the gap between the lifting panel 2 and the front panel 9 when they are both in the initial position.

[0064] In the cabinet sliding panel skeleton model established by using the sketching module, the fitting clearance between the bottom of the cabinet sliding panel and the front panel assembly is detected in the sketching module, and the result is consistent with the fitting clearance in the entity data diagram.

[0065] Example 2: Interference detection is performed on the state of the lifting panel 2 during movement. At the initial stage of starting the lifting panel 2, in order to avoid the bottom of the lifting panel 2 from colliding with the top of the front panel 9, a parabola pointing to the upper right is deliberately set during the trajectory design. After the lifting panel 2 completely avoids the top of the front panel 9, it slides down.

[0066] refer to Figure 6 As shown, Figure 6 a is a schematic diagram showing the lifting panel 2 in the initial position in the cabinet sliding panel skeleton model established using the sketching module; Figure 6 b is a schematic diagram showing the lifting panel 2 in the second position in the cabinet sliding panel skeleton model established using the sketching module; Figure 6 c is a schematic diagram showing the lifting panel 2 in the third position in the cabinet sliding panel skeleton model established using the sketching module. Figure 7 As shown, Figure 7 a represents the entity data diagram of the assembled lifting panel 2 in the CREO software when it is in the initial position; Figure 7 b represents the physical data diagram when the assembled lifting panel 2 is located at the second position in the CREO software; Figure 7 c represents the entity data diagram when the assembled lifting panel 2 is in the third position in the CREO software; Figure 7 As can be seen, the results in the physical data graph are consistent with those in the sketching module. Therefore, the cabinet sliding panel skeleton model created in the sketching module can be used to perform interference detection on the lifting panel 2 throughout its entire motion trajectory. Since the sketching module is used to create the skeleton model, preliminary plan reviews only require line modifications. These line modifications are lightweight data, and after the data position is adjusted, the computer "regeneration" time is very short, improving efficiency. This can significantly reduce the amount of data the computer needs to process.

[0067] Example 3: Detect whether there is interference during the descent of the lifting panel 2. When the triangular guide rail shaft 3 passes the corner of the lower guide rail 7, a sudden drop will occur. This is caused by the instantaneous reduction of the supporting force. Therefore, a smooth transition is required at the corner. Here, the motion trajectory is first detected through the skeleton model to observe whether it can pass smoothly within a certain distance. Figure 8 The sketch module, shown in the figure, shows the schematic diagram of the triangular guide axis 3 in the cabinet sliding panel skeleton model. The sketch module allows for a clear check of whether there is interference when the triangular guide axis 3 passes over the lower guide rail 7. After completing the check in the sketch module, further confirmation of interference is performed in the post-matching solid data diagram.

[0068] The interference detection embodiments at the above three actions clearly show that the skeleton model produced using the sketching module plays an important role in the interference detection process, providing great convenience for the overall design, improving design efficiency, reducing the burden on personnel, and significantly reducing the amount of data that the computer needs to process. The skeleton model produced by the sketching module only includes lines, which is much simpler than the entity. At the same time, the most basic sketching module realizes the production of the skeleton model. In this way, cross-team members can also share data and collaborate on development. It provides the possibility to increase development speed and reduce unnecessary human errors.

[0069] In summary, this embodiment provides a method for establishing a skeleton model using the sketching module in CREO software. Using the sketching module to create a skeleton model avoids the complex tasks of setting "constraints," "variable parameters," and "drive modes" in the CREO software skeleton model module. This greatly facilitates the overall design of the assembly, improves design efficiency, and reduces the burden on technical personnel. The lines in the sketching module are more streamlined than those in solid objects, significantly reducing the amount of data the computer needs to process, reducing the time required for model updates, and accelerating design iteration efficiency. Using the basic sketching module in CREO software reduces the design difficulty for ordinary designers, allowing them to quickly master the design of skeleton models, while also reducing development costs and increasing development speed.
