Description

Technical Field

[0001] The present invention relates to a toy, and particularly to a magnetic - attraction combined robot toy that can avoid self - moving and tipping over. Background Art

[0002] As an outstanding representative of the modern toy industry, vehicle - combined robot toys perfectly integrate the mechanical charm of vehicles and the sense of technology of robots. Through a delicate multi - vehicle combined magnetic - attraction splicing system, these toys achieve the morphological transformation from independent vehicles to an overall robot, bringing an unprecedented interesting playing experience to children. In the field of toy design, this innovative structural design not only demonstrates the charm of engineering aesthetics but also provides an intuitive teaching aid for children to understand mechanical principles.

[0003] Currently, the vehicle - combined robot toys on the market mainly adopt static splicing technology and achieve modular combination through magnetic - attraction interfaces. Although this design ensures the convenience and stability of splicing, it also has obvious limitations: the spliced robot can often only be used as a static ornament and lacks the ability of dynamic movement. To solve this problem, designers set a pull - back spring in the vehicle. After pulling the vehicle backward and then releasing it, the vehicle can move forward by itself. When the vehicle is combined by magnetic - attraction splicing into a robot, the feet of the combined robot are respectively served by two vehicles. After pulling the robot backward for a certain distance and then releasing it, the combined robot can move forward automatically. Although this pull - back structure design can enable the combined robot to move forward automatically, during the subsequent finished - product test process, it is found that when the robot's arm is in the backward - swinging state, the robot is extremely prone to tipping backward when moving forward automatically.

[0004] How to achieve the playing effect that the robot after vehicle combination is not easy to tip over no matter what limb state it is in during its own movement has become a technical problem to be overcome. For this reason, we propose a magnetic - attraction combined robot toy that can avoid self - moving and tipping over. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a magnetic - attraction combined robot toy that can avoid self - moving and tipping over.

[0006] To achieve the above - mentioned purpose, the present invention adopts the following technical solution: A magnetic - attraction combined robot toy that can avoid self - moving and tipping over includes four limbs respectively composed of four vehicles, an excavator body as the upper body of the robot toy, and excavator tracks as the lower - body legs of the robot toy.

[0007] Taking the rear - wheel axis A of the vehicle at the foot of the robot as a reference point, the distance between the first docking central axis C between the upper body and the lower body and the rear - wheel axis A of the vehicle is D1, and taking D1 as a dimension unit n.

[0008] The upper body of the robotic toy is provided with an arm joint axis B. The width of the first limb magnetic connection interface of the arm joint axis B is D3, and D3 = 2 * k1. The distance between the rear wheel axis A of the vehicle and the arm joint axis B of the upper body is D2, and D2 ≥ n + k1;

[0009] The upper end of the lower body of the robotic toy is provided with a first body magnetic connection joint, and the lower end of the lower body of the robotic toy is provided with a second body magnetic connection joint. The widths of both the first body magnetic connection joint and the second body magnetic connection joint are D6, and D6 = 2 * k2. The distance between the second docking central axis E of the second body magnetic connection joint and the rear wheel axis A of the vehicle is D5, and D5 > n and D5 + k2 < D4. The width of the legs of the lower body of the robotic toy is D4, and D4 > 2 * k2 and D4 ≥ 2n.

[0010] Furthermore, the front - rear axle wheelbase of the vehicle serving as the robot's arm is D7, and the front - rear axle wheelbase of the vehicle serving as the robot's foot is D8. D7 = D8 and 2 * D4 ≤ D7 ≤ 3 * D4.

[0011] Furthermore, the excavator body includes a carriage and an excavating arm. The body length of the excavator body when the excavating arm is in a natural hanging state is D9, and D1 + D3 ≥ D9 / 3.

[0012] Furthermore, the excavator track is provided with connection blocks for connecting with the excavator body, and the first body magnetic connection joint is arranged at the connection blocks.

[0013] Furthermore, the excavator track is provided with a flip - cover member that covers the second body magnetic connection joint, so that the second body magnetic connection joint is not exposed outside the excavator track.

[0014] Furthermore, for the four vehicles that respectively form the limbs of the robot, a flip - seat is provided at the rear of the vehicle, and a second limb magnetic connection interface that can be connected to the second body magnetic connection joint of the excavator track is provided at the flip - seat.

[0015] Furthermore, for the four vehicles that respectively form the limbs of the robot, a flip - magnetic connection joint that can be magnetically attracted to the first limb magnetic connection interface is provided at the vehicle floor.

[0016] Furthermore, for the four vehicles that respectively form the limbs of the robot, a heel part is provided at the rear of the vehicle. When the robot is in an upright state, there is a gap between the heel part and the ground plane.

[0017] The beneficial effects of the present invention are as follows: Taking the axis A of the rear wheel of the vehicle on the foot of the robot as the reference point, the distance between the first docking central axis C between the upper body and the lower body and the axis A of the rear wheel of the vehicle is D1. Taking D1 as a dimension unit n, through the correlation restrictions on the combination and installation positions of the upper body, lower body, and limbs of the combined robot toy, as well as the dimension ratios of limb trunk magnetic interfaces, body magnetic connectors, etc., it is ensured that the combined robot toy is not prone to tipping over in any limb state during its own movement, achieving a fun effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Combined with the attached Figure 1 to the attachedFigure 3 As shown in the figure, a magnetic adsorption combined robot toy that can avoid self-tipping includes the limbs of a robot composed of four vehicles respectively. The excavator body 11 serves as the upper body of the robot toy, and the excavator track 12 serves as the lower body legs of the robot toy; the excavator track 12 is provided with a connecting block 123 for connecting with the excavator body 11, and the first body magnetic adsorption joint 121 is arranged at the connecting block 123. The excavator track 12 is provided with a flip piece 124, and the flip piece 124 covers the second body magnetic adsorption joint 122, so that the second body magnetic adsorption joint 122 is not exposed outside the excavator track 12.

[0029] As shown in the attached Figure 3 figure, taking the axis A of the rear wheel of the vehicle at the foot of the robot as the reference point, the distance between the first docking central axis C between the upper body and the lower body and the axis A of the rear wheel of the vehicle is D1, and taking D1 as a dimension unit n;

[0030] Combined with the attached Figure 3 to the attached Figure 5 figure, the upper body of the robot toy is provided with an arm joint axis B. The width of the first limb magnetic adsorption interface 113 of the arm joint axis B is D3, and D3 = 2*k1; the distance between the axis A of the rear wheel of the vehicle and the arm joint axis B of the upper body is D2, and D2 ≥ n + k1. The first limb magnetic adsorption interface 113 is located in front of the first docking central axis C. When the vehicle acting as the arm of the robot toy is magnetically adsorbed and docked with the excavator body 11, the center of gravity of the vehicle is forward, as shown in the attached Figure 4 figure, the gravity load G of the arm is always located at the arm joint axis B;

[0031] Combined with the attached Figure 3 and the attached Figure 7 figure, the upper end of the lower body of the robot toy is provided with a first body magnetic adsorption joint 121, and the lower end of the lower body of the robot toy is provided with a second body magnetic adsorption joint 122. The widths of the first body magnetic adsorption joint 121 and the second body magnetic adsorption joint 122 are both D6, and D6 = 2*k2. The distance between the second docking central axis E of the second body magnetic adsorption joint 122 and the axis A of the rear wheel of the vehicle is D5, and D5 > n and D5 + k2 < D4, so that the center of gravity of the excavator track 12 as the lower body legs of the robot toy is located in front of the first docking central axis C, and it is ensured that the second body magnetic adsorption joint 122 can be accommodated in the flip piece 124.

[0032] The width of the lower body legs of the robot toy is D4, and D4 > 2*k2 and D4 ≥ 2n. Combined with the attached Figure 3 and the attached Figure 4As shown in the figure, the wheelbase of the front and rear axles of the vehicle serving as the robot arm is D7, and the wheelbase of the front and rear axles of the vehicle serving as the robot foot is D8. D7 = D8 and 2*D4 ≤ D7 ≤ 3*D4. The width of the excavator track 12, which is the leg of the lower body of the robot toy, is specifically about between 1 / 2 and 1 / 3 of the vehicle length of the vehicle serving as the limbs of the robot toy. This can not only prevent the robot's legs from being too thin and easily tipping backward under the gravity of supporting the upper body and arms of the robot toy, but also prevent the robot's legs from being too thick and affecting the overall visual aesthetic of the combined robot toy.

[0033] The excavator body 11 includes a carriage 111 and an excavator arm 112. The body length of the excavator body 11 when the excavator arm 112 is in the natural hanging state is D9, and D1 + D3 ≥ D9 / 3. This is to limit the body length D9 of the excavator body 11 when the excavator arm 112 is in the natural hanging state, which can not only ensure the harmonious proportion between the upper body and the legs of the robot toy, but also prevent the situation of tipping during walking due to the large distance between the center of gravity of the upper body of the robot toy and the center of gravity of the robot's legs.

[0034] Combined with the attached Figure 6 and the attached Figure 8 As shown in the figure, for the four vehicles that respectively constitute the limbs of the robot, there is a swivel seat 21 at the rear of the vehicle. At the swivel seat 21, there is a second limb magnetic interface 22 that can be connected to the second body magnetic connection joint 122 of the excavator track 12; there is a swivel magnetic joint 24 at the vehicle floor 23 that can be magnetically attracted to the first limb magnetic interface 113; there is a heel part 25 at the rear of the vehicle. When the robot is in the upright state, there is a gap between the heel part 25 and the ground plane.

[0035] Combined with the attached Figure 3 to the attached Figure 5 As shown in the figure, the first limb magnetic interface 113 is located in front of the first docking central axis C. The vehicle serving as the robot toy arm is magnetically docked with the excavator body 11. The arm joint axis B (i.e., the joint force point of the arm) is also located in front of the first docking central axis C. Combining with the structural proportional relationship between the body length D9 of the excavator body 11 when the excavator arm 112 is in the natural hanging state and D1 + D3 (i.e., D1 + D3 ≥ D9 / 3), even when the combined robot toy arm is in the backward swing state during the robot's own movement, it can ensure that the robot will not tip backward during its own movement.
