Description

Technical Field

[0001] The present invention relates to the technical field of industrial design display, and in particular to a three-dimensional digital industrial design product multi-directional demonstration robot. Background Art

[0002] Three-dimensional digital industrial design products refer to industrial product designs created through three-dimensional modeling technology using computer-aided design (CAD, SolidWorks, UGNX, etc.) software. These product designs not only include product appearance design, but also cover multiple aspects such as structural design, functional design, and human-computer interaction design. Three-dimensional digital design can provide more accurate and intuitive design solutions, help improve design efficiency, reduce production costs, and conduct virtual simulation tests to discover problems in the design in advance. In addition, three-dimensional digital design also supports rapid prototyping, such as 3D printing technology, making the transformation of products from design to prototype faster and more efficient.

[0003] In 3D digital industrial design, demonstration robots are used to visually display designed products. Demonstration robots usually refer to virtual or physical robots used in the design, development or appearance display process. These robots can be used to demonstrate design concepts, test functions or as a component of the final product.

[0004] At present, for industrial design products that have completed the transformation from design to prototype, when performing appearance display, it is difficult to meet the demonstration needs due to the limited angle adjustment range of traditional demonstration robots. For example, the Chinese patent with document number CN217090155U, named a three-dimensional digital industrial design display device, can only rotate but cannot adjust the inclination; another example is the Chinese patent with document number CN213635047U, named a digital industrial design intelligent demonstration device, although the inclination can be adjusted to a certain extent, it can only adjust the semicircular plate, and the bottom of the object to be demonstrated cannot be displayed, and it is not fixed, so there are safety hazards to the product to be demonstrated when adjusting the inclination.

[0027] Example:

[0028] like Figure 1-Figure 5 As shown, a three-dimensional digital industrial design product multi-directional demonstration robot includes a bracket, a fixing ring 6 arranged on the bracket, a corner structure arranged on the fixing ring 6, and a clamping structure connected to the corner structure for fixing the object to be demonstrated and making it move with the corner structure;

[0029] The corner structure includes two first movable rods 9 symmetrically arranged on the fixing ring 6 and two second movable rods 10 symmetrically arranged on the fixing ring 6; the two first movable rods 9 are located on the same straight line, and the two second movable rods 10 are located on the same straight line; the straight line where the two first movable rods 9 are located and the straight line where the two second movable rods 10 are located intersect at the center of the fixing ring 6 and are perpendicular to each other; the two first movable rods 9 are connected by the first fixing rod 20, and the two second movable rods 10 are connected by the second fixing rod 19; the first fixing rod 20 and the second fixing rod 19 are staggered and connected on the axis line of the fixing ring 6;

[0030] The first movable rod 9 rotates in the vertical plane where the fixed ring 6 is located, and the second movable rod 10 rotates in the vertical plane perpendicular to the fixed ring 6;

[0031] The clamping structure is fixedly disposed at the intersection of the first fixed rod 20 and the second fixed rod 19 , and the clamping structure is located in a space surrounded by the two first movable rods 9 and the two second movable rods 10 .

[0032] The bracket includes a base 1, a lifting column 4 arranged on the upper surface of the base 1, and a display stand 5 arranged on the top of the lifting column 4 for placing a fixing ring 6; the lifting column 4 adopts a cylinder or an oil cylinder; an L-shaped bracket 7 is connected to the left and right sides of the fixing ring 6, and the bracket 7 is fixedly connected to the display stand 5 by a fixing bolt 8.

[0033] A wheel 2 is arranged at the bottom of the base 1, and a brake is arranged on the wheel 2. A transmission unit for driving the wheel 2 to rotate is installed at the lower part of the base 1. The transmission unit can adopt a transmission similar to that of a car wheel and is driven by an electric motor. The transmission unit belongs to the prior art; a control cabinet 3 is arranged on the upper surface of the base 1; the control cabinet 3 includes a battery, a control switch, etc. located in the cabinet, and the battery is respectively connected to a small motor 15 and an electric motor for driving the wheel through wires, and a switch is arranged on the wires; the air cylinder, oil cylinder, etc. in this application are matched with each other and belong to the prior art.

[0034] A first slide groove 11 is provided along the circumference at the end of the fixed ring 6 corresponding to the first movable rod 9, and a second slide groove 12 is provided on the inner wall of the first slide groove 11 in a direction perpendicular to the vertical plane where the fixed ring 6 is located, and the second slide groove 12 is connected to the first slide groove 11; a first slider 13 is slidably arranged in the first slide groove 11, and a second slider 14 is connected to the side of the first slide groove 13, and the second slider 14 is slidably connected to the second slide groove 12; the first movable rod 9 is inserted into the first slider 13 and is rotatably connected thereto; the second slide groove 13 and the second slider 14 are used for limiting, so that the first slider 13 can only move back and forth in the first slide groove 11, that is, it can only move along the circumference, and the first slide grooves 11 corresponding to the two first movable rods 9 correspond to each other up and down.

[0035] A small motor 15 is fixedly installed on the outer side of the fixed ring 6 corresponding to the second movable rod 10; a fixing tube 16 passing through the fixed ring 6 is provided on the side of the fixed ring 6 corresponding to the small motor 15, and the output end of the small motor 15 is connected to the transmission shaft 17, and the transmission shaft 17 passes through the fixed tube 16 and is connected to the transmission plate 18; the transmission shaft 17 is arranged along the radial direction of the fixed ring 6, and the transmission plate 18 is arranged perpendicular to the vertical plane where the fixed ring 6 is located, and one end extends away from the fixed ring 6; the second movable rod 10 is rotatably connected to the end of the transmission plate 18 away from the fixed ring 6.

[0036] The two first movable rods 9 are located in the same straight line, and the two second movable rods 10 are located in the same straight line. The two straight lines are perpendicular to each other and intersect at the center of the fixed ring 6. The first fixed rod 20 and the second fixed rod 19 are arranged to connect the first movable rod 9 and the second movable rod 10 in order to associate the movements of the two groups of movable rods.

[0037] The second movable rod 10 is connected to the transmission plate 18 at a position outside the fixed ring 6, so that the straight line where the two second movable rods 10 are located forms an angle with the vertical plane where the fixed ring 6 is located. The size of the angle is related to the outward extension length of the transmission plate 18 and also to the connection position of the second movable rod 10 and the transmission plate 18.

[0038] When the small motor 15 is started, the small motor 15 drives the transmission shaft 17, the transmission shaft 17 drives the transmission plate 18 to rotate, the transmission plate 18 drives one of the second movable rods 10 to rotate in a vertical plane perpendicular to the fixed ring 6, and the second movable rod 10 drives the first fixed rod 20 and the other second movable rod 10 to move through the second fixed rod 19; the two second movable rods 10 make circular motions, and the two first movable rods 9 swing; because the first movable rod 9 is associated with the second movable rod 10 in motion and is perpendicular to each other; taking the second movable rod 10 at the left end and the first movable rod 9 at the top as an example, when the second movable rod 10 moves to the high point position, the first movable rod 9 at the top swings to the right of the vertical center line of the fixed ring 6, and when the second movable rod 10 moves to the low point position, the first movable rod 9 at the top swings to the left of the vertical center line of the fixed ring 6; the movement distance in the up and down direction determines the angle of clockwise or counterclockwise rotation of the object to be demonstrated in the vertical plane, fully demonstrating the shape of the bottom, top and side of the object to be demonstrated.

[0039] Because the second movable rod 10 is in circular motion, the second movable rod 10 will move out of the vertical plane where the fixed ring 6 is located. At this time, since the straight lines where the first movable rod 9 and the second movable rod 10 are located intersect at the center of the fixed ring 6, only horizontal motion is considered. Even if the second movable rod 10 moves out of the fixed ring 6, it will only affect the first movable rod 9 to make it rotate itself. Even if the first movable rod 9 and the second movable rod 10 can move slightly up and down in the corresponding slider due to manufacturing accuracy problems, there will be no other impact; the horizontal movement distance of the second movable rod 10 determines the clockwise and counterclockwise rotation angles of the object to be demonstrated in the horizontal plane, that is, the horizontal movement of the second movable rod 10 can fully display the part of the object to be demonstrated that is blocked by the inner side of the fixed ring; combined with the aforementioned display method of the bottom, top and side of the object to be demonstrated, the purpose of multi-angle display is achieved; the circular motion of the second movable rod 10 enables the object to be demonstrated to achieve a rotation angle in the horizontal plane while turning an angle in the vertical plane; thereby more fully displaying the features of the top and bottom of the part of the side of the object to be demonstrated that is blocked by the inner side of the fixed ring.

[0040] The transmission plate 18 includes a straight plate extending outwardly perpendicular to the fixed ring 6, and an inclined plate connected to the end of the straight plate; the inclined plate is set at an angle to the straight plate; the inclined plate is inclined toward the axial center line direction of the fixed ring 6; the second movable rod 10 is rotatably connected to the inclined plate, and the second movable rod 10 is perpendicular to the surface of the inclined plate; increasing the horizontal rotation angle also makes the second movable rod 10 more stable when rotating; when the second movable rod 10 rotates, it drives the second fixed rod 19, but because the second fixed rod 19 is connected to the first fixed rod 20, the first fixed rod 20 is restricted by the first slide groove 11 and the second slide groove 12, thereby preventing the second fixed rod 19 from making a circular motion, so when the second movable rod 10 makes a circular motion with the transmission plate 18, the second movable rod 10 and the through hole opened in the transmission plate 18 to accommodate the second movable rod 10 will rotate relative to each other to ensure that the two do not affect each other, so the second fixed rod 19 and the first fixed rod 20 will only swing in the vertical plane and rotate in the horizontal plane.

[0041] The clamping structure includes a fixed block 21 fixed at the intersection of the first fixed rod 20 and the second fixed rod 19, and a movable splint structure connected to the fixed block 21 and arranged on the axis of the fixed ring 6; the movable splint structure includes a cylinder seat 22 fixedly connected to the fixed block 21, the cylinder seat 22 is connected to the piston rod 23, the piston rod 23 passes through the fixed block 21 and is slidably connected thereto; a fixed sleeve 24 is fixedly installed on one side of the fixed block 21 close to the fixed ring 6, and the fixed sleeve 24 is sleeved on the outside of the piston rod 23; a movable sleeve 25 is fixedly provided on the end of the piston rod 23 away from the fixed block 21; the movable sleeve 2 5 is located between the fixed sleeve 24 and the fixed ring 6; at least two first fixed seats 26 are equidistantly arranged on the outer side of the movable sleeve 25 along the circumferential direction, and second fixed seats 36 corresponding to the first fixed seats 26 are equidistantly arranged on the outer side of the fixed sleeve 24 along the circumferential direction; the number of the first fixed seats 26 and the second fixed seats 36 is equal, and they correspond to the same straight line in pairs, and the straight line is parallel to the axis of the fixed ring 6, and the axis of the fixed ring 6 is collinear with the axis of the piston rod 23, the fixed sleeve 24 and the movable sleeve 25; the first fixed seat 26 is rotatably connected to one end of the support rod 27; the second fixed seat 36 is rotatably connected to one end of the second support rod The support rod 27 is staggered with the second support rod and is rotatably connected with the same fixed shaft 28 at the staggered position; the support rod 27 is inclined toward the second support rod, and the second support rod is inclined toward the support rod 27. The line connecting the support rod 27 and the top of the second support rod is parallel to the axis of the piston rod 23; a clamping plate 39 is arranged at a distance from the top of the corresponding support rod 27 and the second support rod, and the clamping plate 39 is parallel to the axis of the fixing ring 6. The position of the clamping plate 39 corresponding to the other end of the support rod 27 is fixedly connected with the first fixing block 29, and the position of the clamping plate 39 corresponding to the other end of the second support rod is fixedly connected A second fixed block 31 is connected; the end of the support rod 27 is fixedly connected to the first connecting rod 30, and the upper part of the first connecting rod 30 is rotatably connected to the first fixed block 29; the second fixed block 31 is provided with a vertical groove 32 from the top to the bottom, and a lateral groove 33 is provided from the side; the lateral groove 33 passes through the second fixed block 31 horizontally; the vertical groove 32 is connected to the lateral groove 33; a roller 34 is arranged in the vertical groove 32, and the roller 34 rolls in a direction parallel to the axial center line of the fixing ring 6; the end of the second support rod is fixedly connected to the second connecting rod 35; the upper part of the second connecting rod 35 passes through the lateral groove 33 and the roller 34.

[0043] The roller 34 is connected to the second connecting rod 35 and is controlled by it to roll at the bottom of the vertical groove 32; the bottom of the vertical groove 32 is closer to the second fixed block 31 than the bottom of the lateral groove 33; the first connecting rod 30 and the second connecting rod 35 are both rectangular; when starting to work, the piston rod 23 contracts, the piston rod 23 drives the movable sleeve 25 to contract, and the movable sleeve 25 drives the bottom of the support rod 27 to move toward the fixed sleeve 24 through the first fixed seat 26, and the support rod 27 is raised. The support rod 27 drives the second support rod to rotate around the second fixed seat 36 through the fixed shaft 28, and the top of the second support rod moves toward the fixed sleeve 24 to support the clamping plate 39; the roller 34 is provided to facilitate the rotation of the second support rod to prevent the contact between the second fixed block 31 and the second fixed block 31 from being damaged due to stress concentration during the rotation and lifting of the clamping plate; after the clamping plate 39 is lifted, the object to be demonstrated is placed between multiple clamps and then the piston rod 23 is examined to clamp the object to be demonstrated.

[0044] Elastic bands 40 are arranged between adjacent clamping plates 39. The elastic bands 40 on the same circumference are a group. At least one group of elastic bands 40 is arranged along the axial centerline direction of the fixing ring 6. The number of elastic bands 40 and the width of the clamping plates 39 can be determined according to the shape of the object to be demonstrated. The more irregular the shape of the object to be demonstrated, the narrower the width of the clamping plates 39 should be set. The number of clamping plates 39 should be minimized while maintaining the clamping stability. The irregular object to be demonstrated is restrained and fixed by the elastic bands 40 between adjacent clamping plates 39. In this case, it is also necessary to increase the number of elastic bands 40 or adjust the elasticity of the elastic bands 40. The front end of the first fixing rod 20 is connected to an arc-shaped protective member 41.

[0046] Embodiment 2:

[0048] Embodiment three:

[0049] Considering the intelligent needs of the demonstration robot, a touch screen is integrated on the control cabinet 3, through which the clamping structure and the corner structure can be remotely controlled. Users can easily select different demonstration modes, adjust the clamping force, and set the rotation speed and angle of the corner structure through the intuitive interface on the touch screen. In addition, the touch screen can also display relevant information of the object to be demonstrated, such as name, specifications, characteristics, test environment, assembly relationship, etc., so that the audience can obtain more product knowledge while watching the demonstration.

[0050] To ensure the safety of the demonstration process, the control cabinet also has a built-in emergency stop mechanism. When an abnormal situation is detected, such as excessive clamping force, corner structure jamming, or dangerous factors in the demonstration environment, the system will immediately initiate the emergency stop procedure and cut off the power output to ensure the safety of operators and spectators.

[0051] In order to meet the demonstration needs of different occasions, the demonstration robot is also designed with a variety of replaceable clamping plates 39. Users can choose clamping plates 39 of different materials, shapes and sizes according to the characteristics of the objects to be demonstrated to achieve the best demonstration effect. For example, for fragile or delicate objects to be demonstrated, a soft and elastic clamping plate 39 can be selected to reduce damage to the objects.

[0052] In addition, the demonstration robot is equipped with an environmental adaptation system. The system can automatically adjust the working state of the demonstration robot according to factors such as light, temperature and humidity in the demonstration environment. For example, in a dark environment, the system will automatically enhance the lighting of the clamping structure and corner structure to ensure that the audience can clearly see the demonstration process. In a high-temperature environment, the system will start the cooling device to prevent the equipment from overheating and ensure the continuity and stability of the demonstration.

[0053] Through these innovative designs, the demonstration robot can not only provide efficient and accurate demonstration services, but also adapt to various complex demonstration environments and meet the needs of different users, becoming an ideal choice for showcasing product and technological innovations.
