The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] The following describes the digital modeling device, method, host computer, storage medium and program product of the embodiment of the present application with reference to the accompanying drawings. In view of the problems of high production cost, long production time and easy waste of resources of traditional sample parts mentioned in the above background technology, the present application provides a digital modeling device, the host computer is used to receive the relative distance between the surface to be modeled of the target digital model and the preset virtual plane, and based on the relative distance, the telescopic rod assembly and the positioning push rod assembly are controlled to perform the target action, specifically, the telescopic length of each telescopic rod is adjusted according to the relative distance, and the positioning push rod assembly is used to move multiple telescopic rods to the target position to complete the rapid imitation of the surface to be modeled of the target digital model, and the same device can be used for different designs or different versions of the same design, which increases the flexibility and reuse rate of the modeling device, avoids waste of resources, reduces the time required for sample production and the production cost of the physical object, and thus reduces the development time of the sample parts in the whole vehicle design process. Thus, the problems of long sample production time, high production cost and easy waste of resources in the prior art are solved.

[0031] Specifically, Figure 1 A schematic diagram of a digital imaging device provided in an embodiment of the present application.

[0032] like Figure 1 As shown, the digital imaging device 10 includes: a plurality of telescopic rod assemblies 201, a plurality of positioning push rod assemblies 202, a host computer 203 and a device body 204.

[0033] Among them, multiple positioning push rod assemblies 202 are arranged on the device body 204, which are used to move multiple telescopic rods to the target position and fix the multiple telescopic rods; multiple telescopic rod assemblies 201 are fixed on the device body 204, which are used to adjust the telescopic length of each telescopic rod according to the relative distance; the upper computer 203 receives the relative distance between the surface to be imitated of the target digital model and the preset virtual plane, and controls the telescopic rod assembly 201 and the positioning push rod assembly 202 to perform the target action based on the relative distance to complete the imitation of the surface to be imitated.

[0034] It can be understood that the digital modeling device of the embodiment of the present application includes a device body 204, a host computer 203, multiple positioning push rod assemblies 202 and multiple telescopic rod assemblies 201. The host computer 203 is used to receive the relative distance between the surface to be imitated of the target digital model and the preset virtual plane, and control the telescopic rod assembly 201 and the positioning push rod assembly 202 to perform the target action based on the relative distance, specifically adjusting the telescopic length of each telescopic rod according to the relative distance. The positioning push rod assembly is used to move the multiple telescopic rods to the target position to complete the rapid imitation of the surface to be imitated of the target digital model, reducing the time required for sample production and the production cost of the physical object, thereby reducing the development time of the sample during the vehicle design process.

[0035] Among them, the target digital model is a three-dimensional digital model of an object or item that contains complete geometric information (shape, size, surface, etc.) created by computer software; the surface to be imitated is a specific surface area in the target digital model that needs to be physically copied or simulated, such as the left rear door of a car body model; the preset virtual plane is a virtual plane opposite to the target digital model, which is a fixed reference plane.

[0036] In addition, it should be noted that after receiving the relative distance data, the host computer 204 needs to convert the relative distance data into the moving distance data of each telescopic rod, and control the telescopic rod assembly 201 and the positioning push rod assembly 202 to perform the target action based on the moving distance data to complete the digital imitation shape.

[0037] In the embodiment of the present application, the telescopic rod assembly 201 includes: a telescopic rod 301, a return spring 302, an upper shell 303, a spring 304, a fixing card 305, a rubber card 306, a coil 307 and a lower shell 308, wherein one end of the return spring 302 is in contact with the telescopic rod 301, and the other end is in contact with the upper shell 303; a magnetic strip is provided at the conical bottom of the fixing card 305; the spring 304 is provided between the fixing card 305 and the upper shell 303; the rubber card 306 is used in combination with the fixing card 305 to fix the telescopic rod 301; and the coil 307 is provided on the lower shell 308.

[0038] like Figure 2As shown, the telescopic rod assembly consists of a telescopic rod 301 (also called a rod), a reset spring 302, an upper shell 303, a spring 304, a fixing card 305, a rubber card 306, a coil 307, a lower shell 308, and a rotating member 309. One end of the reset spring 302 contacts the telescopic rod 301 and the other end contacts the upper shell 303, which plays a role of rapid reset. The fixing card 305 has a conical bottom inside and a magnetic strip is provided, which cooperates with the upper shell 303. A spring 304 and a rubber card 306 are provided between the two. They are used in combination with the fixing card 305 to fix the telescopic rod 301. The coil 307 is provided on the lower shell 308, and a magnetic field will be generated when power is turned on.

[0039] In addition, it should be noted that a rotating member is provided at the bottom of the rod 301 to better imitate the curved surface.

[0040] In the embodiment of the present application, the host computer 203 is further used to: control the coil 307 to be energized, and use the magnetic field generated by the coil 307 to separate the fixing card 305 from the rubber card 306, so that the telescopic rod 301 is in an active state; after the telescopic rod 301 moves to the target position, the control coil 307 is de-energized, so that the fixing card 305 and the rubber card 306 are pressed tightly to complete the fixation of the telescopic rod 301.

[0041] It is understandable that in the embodiment of the present application, when the digital analog device 10 is working, the upper computer 203 controls the coil 307 to generate a magnetic field to push the fixed card 305 to move upward, at which time the rubber card 306 is separated from the fixed card 305, and the telescopic rod 301 is in an active state. After the telescopic rod 301 reaches a specified state, the coil 307 is de-energized, and under the action of the spring 304, the fixed card 305 contacts the rubber card 306, clamps the telescopic rod 301, and completes the fixation of the telescopic rod 301.

[0042] In the embodiment of the present application, the positioning push rod assembly 202 includes: a fixed bracket 401, an X-axis screw 402, an X-axis nut 403, a Y-axis screw 404, a movable bracket 405, and an electric push rod 406, wherein the movable bracket 405 is fixed to the X-axis nut 403, and under the action of the X-axis screw 402, the movable bracket 405 can move left and right relative to the fixed bracket 401; the electric push rod 406 cooperates with the Y-axis screw 404 to realize the forward and backward movement of the electric push rod 406 relative to the movable bracket 405; the X-axis nut 403 cooperates with the X-axis screw 404, and the Y-axis screw 404 cooperates with the Y-axis nut on the movable bracket 405 to realize the movement of the electric push rod 406 in a plane.

[0043] like Figure 3As shown, the positioning push rod of the embodiment of the present application is composed of a fixed bracket 401, an X-direction lead screw 402, an X-direction nut 403, a Y-direction lead screw 404, a movable bracket 405, and an electric push rod 406. Among them, the movable bracket 405 is fixed to the X-direction nut 403, and under the action of the X-direction lead screw 402, it can move left and right relative to the fixed bracket 401, and the electric push rod 406 cooperates with the Y-direction lead screw 404 to move forward and backward relative to the movable bracket 405. The lead screw nuts in two directions cooperate with each other to realize the movement of the electric push rod 406 in the plane, and the electric push rod 406 can be accurately controlled to move up and down.

[0044] In the embodiment of the present application, the host computer 203 is further used to: control the electric push rod 406 to push the target telescopic rod to the target position.

[0045] It is understandable that the host computer 203 in the embodiment of the present application can control the electric push rod 406 to push the target telescopic rod to the target position according to the relative distance.

[0046] In an embodiment of the present application, the host computer 203 is also used to: construct a preset virtual plane relative to the target digital model, and set a uniformly distributed dot matrix on the preset virtual plane; project the dot matrix from the preset virtual plane to the surface to be imitated of the target digital model; calculate the relative distance from each projection point on the surface to be imitated to the preset virtual plane.

[0047] It can be understood that the host computer 203 of the embodiment of the present application is also used to construct a preset virtual plane relative to the target digital model, and set a uniformly distributed dot matrix on the preset virtual plane, project the dot matrix from the preset virtual plane to the surface to be imitated of the target digital model, and calculate the relative distance from each projection point on the surface to be imitated to the preset virtual plane, so as to subsequently control multiple telescopic rod modules and multiple positioning push rods to perform target actions based on the relative distance to complete the profiling of the surface to be imitated, wherein the distance between the preset virtual plane and the surface to be imitated of the target digital model is obtained as follows: Figure 4 shown.

[0048] The digital imaging device of the embodiment of the present application is described below by a specific embodiment. Figure 5 As shown in FIG. 1 , it mainly includes two parts: a telescopic rod assembly and a positioning push rod assembly. The telescopic rod assembly (also called a telescopic rod module) is as follows: Figure 2 As shown in FIG. 1 , the telescopic rod can reciprocate under the action of external force and hover at a certain position under the action of electromagnetic force. Multiple telescopic rods form a dot matrix plane. Positioning push rod assembly (also called positioning push rod), such as Figure 3As shown, an electric push rod is arranged on it, which can accurately control the extension of the rod. The control screw nut can realize the movement of the electric push rod on the lattice plane. When it moves to the specified position, the electric push rod pushes the telescopic rod module to extend, and the telescopic rod module is fixed by electromagnetic force. Repeating the above steps can realize the adjustment of all rods on the plane, thereby realizing the profiling of the digital model.

[0049] When the digital analog modeling device works as a whole, the moving distance data (i.e., relative distance) of all telescopic rods are obtained from the host computer, and the motion trajectory of the electric push rod is automatically arranged according to the data. After the electric push rod moves to the position of the specified telescopic rod, the distance that the telescopic rod needs to be extended is called. At this time, the telescopic rod coil is energized, the fixed card is lifted by the magnetic force, and the rod is in a movable state. After the electric push rod pushes the telescopic rod to the specified position, the telescopic rod coil is de-energized. The fixed card presses the rubber card under the action of the spring to fix the rod. Repeat the above operations to complete the adjustment of all telescopic rods and realize the imitation of the digital analog surface. The device can be reset by energizing all telescopic rod coils.

[0050] The digital modeling device proposed in the embodiment of the present application includes a device body, a host computer, a positioning push rod assembly and a telescopic rod assembly. The host computer is used to receive the relative distance between the surface to be imitated of the target digital model and the preset virtual plane, and control the telescopic rod assembly and the positioning push rod assembly to perform the target action based on the relative distance, specifically adjusting the telescopic length of each telescopic rod according to the relative distance. The positioning push rod assembly is used to move multiple telescopic rods to the target position to complete the rapid imitation of the surface to be imitated of the target digital model. The same device can be used for different designs or different versions of the same design, which increases the flexibility and reuse rate of the imitation device, avoids waste of resources, reduces the time required for sample production and the production cost of the physical object, and thus reduces the development time of the sample during the vehicle design process.

[0051] Next, the digital image shaping method proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0052] Figure 6 It is a flow chart of the digital modeling method of an embodiment of the present application.

[0053] like Figure 6 As shown, the digital contouring method, based on the digital contouring device mentioned above, performs digital contouring, comprising the following steps:

[0054] In step S10, a preset virtual plane relative to the target digital model is constructed, and a uniformly distributed dot matrix is ​​set on the preset virtual plane.

[0055] It is understandable that the embodiments of the present application can construct a preset virtual plane relative to the target digital model, and set a uniformly distributed dot matrix on the preset virtual plane to facilitate subsequent digital model shaping.

[0056] In step S11 , the dot matrix is ​​projected from a preset virtual plane to the surface to be profiled of the target digital model.

[0057] In step S12, the relative distance from each projection point of the surface to be profiled to the preset virtual plane is calculated.

[0058] It can be understood that the embodiment of the present application can calculate the relative distance X from each projection point of the surface to be profiled to the preset virtual plane.

[0059] In step S13, the plurality of telescopic rod assemblies and the plurality of positioning push rod assemblies are controlled to perform a target action based on the relative distance to complete the profiling of the surface to be profiled.

[0060] It can be understood that the embodiments of the present application can control the telescopic rod assembly and the positioning push rod assembly to perform the target action based on the relative distance control to complete the profiling of the surface to be profiled, thereby reducing the time required for sample production and the production cost of the actual object, thereby reducing the development time of the sample during the vehicle design process.

[0061] It should be noted that the embodiment of the present application also needs to convert the relative distance data into the moving distance data of each telescopic rod, and control the telescopic rod assembly and the positioning push rod assembly to perform the target action based on the moving distance data.

[0062] The following describes the process of the digital modeling method of the present application through a specific embodiment, and fits the surface shape of a three-dimensional object by controlling the matrix, such as Figure 7 As shown, including:

[0063] S101: Establish a virtual plane relative to the digital model, and project the dot matrix onto the digital model surface that needs to be profiled, such as Figure 4 shown.

[0064] S102: Calculate the relative distance X from the projection point to the virtual plane.

[0065] S103: Save the X of the dot matrix and send it to the profiling device.

[0066] S104: The digital contouring device controls the rod to extend to a corresponding position according to the X value of different points.

[0067] S105: All rods are extended to the designated positions, and the imitation of the logarithmic model is completed. The corresponding materials can be attached to the rods to make the imitation surface smoother and neater.

[0068] It should be noted that the above explanations of the embodiment of the digital profiling device are also applicable to the digital profiling method of this embodiment, which will not be described in detail here.

[0069] According to the digital modeling method proposed in the embodiment of the present application, a preset virtual plane relative to the target digital model can be constructed, and the dot matrix on the preset virtual plane can be projected onto the surface to be imitated of the target digital model, and then the relative distance from each projection point of the surface to be imitated to the preset virtual plane is calculated, and the telescopic rod assembly and the positioning push rod assembly are controlled to perform the target action based on the relative distance, specifically, the telescopic length of each telescopic rod is adjusted according to the relative distance, and the positioning push rod is used to move multiple telescopic rods to the target position to complete the rapid imitation of the surface to be imitated of the target digital model. The same device can be used for different designs or different versions of the same design, which increases the flexibility and reuse rate of the profiling device, avoids waste of resources, reduces the time required for sample production and the production cost of the physical object, and thus reduces the development time of the sample during the vehicle design process.
