Abstract
Description
Technical Field
[0001] The invention relates to a toy, in particular to a magnetically attracted combined robot toy which can avoid self-movement and tipping. Background Art
[0002] As an outstanding representative of the modern toy industry, vehicle-combined robot toys perfectly combine the mechanical charm of vehicles with the technological sense of robots. This type of toy achieves the transformation from an independent vehicle to an integrated robot through an ingenious multi-vehicle combination magnetic splicing system, bringing children an unprecedented fun and play experience. In the field of toy design, this innovative structural design not only demonstrates the charm of engineering aesthetics, but also provides children with intuitive teaching aids to understand mechanical principles.
[0003] At present, the vehicle-combined robot toys on the market mainly use static splicing technology to achieve modular combination through magnetic interfaces. Although this design ensures the convenience and stability of splicing, it also has obvious limitations: the assembled robot can often only be used as a static ornament and lacks dynamic movement ability. In order to solve this problem, the designers set up a pull-back spring in the car, and after the car is dragged backwards, it is released, and the car can move forward on its own. When the car combination is magnetically spliced and combined into a robot, the two feet of the combined robot are respectively played by the two cars. After dragging the robot backwards for a distance and then releasing it, the combined robot can move forward automatically. Although this pull-back structure design can realize the automatic forward movement of the combined robot, in the subsequent finished product test process, it was found that when the robot arm is in the back swing state, the robot is very likely to tip backward when it moves forward automatically.
[0004] How to achieve the fun effect that the robot after the vehicle combination is not prone to tipping over when it moves by itself, regardless of the limb state, has become a technical problem that needs to be overcome. To this end, we propose a magnetic combined robot toy that can avoid tipping over by itself. Summary of the invention
[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a magnetically attracted combined robot toy which can avoid self-movement and tipping.
[0006] To achieve the above object, the present invention adopts the following technical solution: a magnetic combined robot toy that can avoid self-movement and tipping, including four limbs composed of four vehicles respectively, an excavator body as the upper body of the robot toy, and an excavator track as the lower body legs of the robot toy; Taking the rear wheel axis A of the robot foot as the reference point, the distance between the first docking center axis C between the upper body and the lower body and the rear wheel axis A is D1, and D1 is a dimension unit n; The upper body of the robot toy is provided with an arm joint axis B, the width of the first limb magnetic interface of the arm joint axis B is D3, D3=2*k1; the distance between the rear wheel axis A and the arm joint axis B of the upper body is D2, D2≥n+k1; A first body magnetic joint is provided at the upper end of the lower body of the robot toy, and a second body magnetic joint is provided at the lower end of the lower body of the robot toy. The widths of the first body magnetic joint and the second body magnetic joint are both D6, D6=2*k2, and the distance between the second docking center axis E of the second body magnetic joint and the rear wheel axis A of the vehicle is D5, D5>n and D5+k2<D4; the width of the legs of the lower body of the robot toy is D4, D4>2*k2 and D4≥2n.
[0007] To further elaborate, the wheelbase between the front and rear axles of the vehicle serving as the robot arm is D7, and the wheelbase between the front and rear axles of the vehicle serving as the robot foot is D8, D7=D8, and 2*D4≤D7≤3*D4.
[0008] It is further explained that the excavator body includes a car body and an excavating arm. The body length of the excavator body when the excavating arm is in a naturally drooping state is D9, and D1+D3≥D9 / 3.
[0009] It is further explained that the excavator crawler is provided with a connecting block for connecting with the excavator body, and the first body magnetic suction joint is provided at the connecting block.
[0010] It is further explained that the excavator track is provided with a flap member, and the flap member covers the magnetic attraction joint of the second body so that the magnetic attraction joint of the second body is not exposed on the excavator track.
[0011] It is further explained that the four vehicles respectively constitute the four limbs of the robot, and a flip seat is provided at the rear of the vehicle, and the flip seat is provided with a second limb magnetic suction interface that can be connected to the second body magnetic suction joint of the excavator crawler.
[0012] It is further explained that the four vehicles, which respectively constitute the four limbs of the robot, are provided with flip magnetic suction joints on the bottom plates thereof which can be magnetically attracted to the magnetic suction interface of the first limb.
[0013] To further explain, the four vehicles, which respectively constitute the four limbs of the robot, are provided with heels at the rear ends thereof, and when the robot is in an upright state, there is a gap between the heels and the ground plane.
[0014] The beneficial effects of the present invention are as follows: the present invention takes the rear wheel axis A of the robot's foot as the reference point, the distance between the first docking center axis C between the upper body and the lower body and the rear wheel axis A is D1, and D1 is a size unit n. By limiting the combined installation positions of the upper body, lower body, and limbs of the combined robot toy, as well as the associated restrictions between the size ratios of the limb magnetic interface, the body magnetic joint, etc., it is ensured that the combined robot toy is not prone to tipping over no matter what limb state it is in when it moves.

DETAILED DESCRIPTION
[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Combined with Figure 1 To Attachment Figure 3 As shown, a magnetic combined robot toy that can avoid self-movement and tipping includes robot limbs composed of four vehicles, an excavator body 11 as the upper body of the robot toy, and an excavator track 12 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 a first body magnetic suction joint 121 is provided at the connecting block 123. The excavator track 12 is provided with a flip cover 124, which covers the second body magnetic suction joint 122 so that the second body magnetic suction joint 122 is not exposed to the excavator track 12.
[0026] As attached Figure 3 As shown, with the rear wheel axis A of the robot foot as the reference point, the distance between the first docking center axis C between the upper body and the lower body and the rear wheel axis A is D1, with D1 being a size unit n; Combined with Figure 3 To Attachment Figure 5 As shown, the upper body of the robot toy is provided with an arm joint axis B, and the width of the first limb magnetic interface 113 of the arm joint axis B is D3, 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, D2≥n+k1, and the first limb magnetic interface 113 is located in front of the first docking center axis C. When the vehicle serving as the arm of the robot toy is magnetically docked with the excavator body 11, the center of gravity of the vehicle is forward, as shown in the attached figure. Figure 4 As shown, the gravity load G of the arm is always located at the axis B of the arm joint; Combined with Figure 3 and attached Figure 7 As shown, a first body magnetic joint 121 is provided at the upper end of the lower body of the robot toy, and a second body magnetic joint 122 is provided at the lower end of the lower body of the robot toy. The widths of the first body magnetic joint 121 and the second body magnetic joint 122 are both D6, D6=2*k2, and the distance between the second docking center axis E of the second body magnetic joint 122 and the rear wheel axis A of the vehicle is D5, D5>n and D5+k2<D4, so that the center of gravity of the excavator crawler 12 when serving as the lower body leg of the robot toy is located in front of the first docking center axis C, and ensure that the second body magnetic joint 122 can be stored in the flip cover 124.
[0027] The width of the legs of the lower body of the robot toy is D4, D4>2*k2 and D4≥2n. Figure 3 and attached Figure 4As shown, the wheelbase of the front and rear axles of the vehicle as the robot arm is D7, and the wheelbase of the front and rear axles of the vehicle as the robot foot is D8, D7=D8 and 2*D4≤D7≤3*D4. The width of the excavator crawler 12 as the lower body and legs of the robot toy is specifically about 1 / 2 to 1 / 3 of the length of the vehicle as the limbs of the robot toy, which can prevent the robot legs from being too thin and easily falling backwards under the gravity of the upper body and arms of the robot toy, and can also prevent the robot legs from being too thick and affecting the overall visual beauty of the combined robot toy.
[0028] The excavator body 11 includes a carriage 111 and an excavator arm 112. The length of the excavator body 11 when the excavator arm 112 is in a naturally drooping state is D9, and D1+D3≥D9 / 3, so as to limit the length D9 of the excavator body 11 when the excavator arm 112 is in a naturally drooping state, which can not only ensure the coordinated proportions of the upper body and legs of the robot toy, but also prevent the center of gravity of the upper body of the robot toy from being too far away from the center of gravity of the robot legs, causing the robot toy to tip over during walking.
[0029] Combined with Figure 6 and attached Figure 8 As shown, four vehicles constitute the robot's limbs respectively, and a flip seat 21 is provided at the rear of the vehicle. The flip seat 21 is provided with a second limb magnetic interface 22 that can be connected to the second body magnetic interface 122 of the excavator track 12; a flip magnetic joint 24 that can be magnetically attracted to the first limb magnetic interface 113 is provided at the bottom plate 23 of the vehicle; a heel part 25 is provided at the rear of the vehicle, and when the robot is in an upright state, there is a gap between the heel part 25 and the ground plane.
[0030] Combined with Figure 3 To Attachment Figure 5 As shown, the first limb magnetic interface 113 is located in front of the first docking axis C, the vehicle serving as the robot toy arm is magnetically docked with the excavator body 11, and the arm joint axis B (i.e., the force point of the arm joint) is also located in front of the first docking axis C. Combined with the structural proportional relationship between the body length D9 and D1+D3 of the excavator body 11 when the excavating arm 112 is in a naturally drooping state (i.e., D1+D3≥D9 / 3), even if the combined robot toy arm is in a rearward swing state when the robot moves by itself, it can be ensured that the robot will not fall backwards when it moves by itself.
