Description

Technical Field

[0001] This utility model belongs to the field of humanoid toy technology, and more specifically, relates to a foot structure for a humanoid toy. Background Technology

[0002] Different humanoid toys offer players different experiences. Plush toys and dolls can usually serve as decorations, and players can also release stress by touching and hugging them. Mecha toys, on the other hand, are movable or static toys designed based on mechanical armor and combat robots from science fiction, anime, or military themes. They typically combine a sense of technology, combat elements, and playability.

[0003] Some mechs incorporate wheels at the bottom of their feet for easier movement, with the basic foot outline pieced together on the outside of the wheels. Drive motors can also be installed on the wheels, allowing the mech to move automatically. Alternatively, a drive motor can be omitted, and the mech can be propelled by a human.

[0004] However, the inventors discovered that when the mech is standing, the rollers are not conducive to its stability and it is easy to slip, especially on smooth surfaces. There is currently no technical solution to solve this problem. Utility Model Content

[0005] This invention addresses the technical problem of slipping when standing on the feet of current humanoid toys with wheels. By incorporating a rotatable support plate, the toy is supported by the ground, providing better support and allowing it to stand stably. Furthermore, while providing support, it can also move smoothly under the drive of a motor.

[0006] The technical solution adopted is as follows: A foot structure for a humanoid toy, comprising:

[0007] The rear wheel is located at the rear of the foot.

[0008] Two front wheels, located at the front of the foot;

[0009] The connecting part is rotatably connected to both the rear wheel and the front wheel;

[0010] A support plate is rotatably disposed between the two front wheels. A first limiting block is fixedly connected to the rear end of the support plate, and a second limiting block is fixedly connected to the front end of the support plate. The first limiting block is used to abut against the connecting part when the bottom surface of the support plate is rotated to the same height as the lower edge of the front wheel, and the second limiting block is used to abut against the connecting part when the support plate is rotated to its lowest point, which is higher than the lower edge of the front wheel.

[0011] Optionally, the diameter of the rear wheel is larger than that of the front wheel, the housing of the drive motor is fixedly connected to the connecting part, and the output shaft of the drive motor is connected to the axle of the rear wheel.

[0012] Optionally, the first limiting block and the second limiting block are integrally formed with the support plate.

[0013] Optionally, the first limiting block and the second limiting block are mounted on the support plate by fasteners or snap-fit ​​structures.

[0014] Optionally, the first limiting block is formed by extending to the left and right sides beyond the front wheel from the rear end of the support plate.

[0015] Optionally, the bottom surface of the support plate has anti-slip texture.

[0016] Optionally, the bottom surface of the support plate has a V-shaped cross-section in the front-rear direction, and the included angle of the V-shape is between 165° and 175°.

[0017] Optionally, the front end of the bottom of the support plate is a slope that gradually decreases from front to back.

[0018] Optionally, one end of the rear wheel is rotatably connected to the rear end of a connecting part, the same end of the front wheel is rotatably connected to the front end of the connecting part, the other end of the rear wheel is rotatably connected to the rear end of another connecting part, and the same end of the front wheel is rotatably connected to the front end of yet another connecting part.

[0019] Optionally, the rotatable arrangement between the two front wheels means that a third connecting shaft is fixedly connected to the support plate, and the third connecting shaft is rotatably inserted into the axle of the front wheel.

[0020] This utility model has the following beneficial effects:

[0021] (1) By rotating the support plate to the same height as the lower edge of the front wheel, the humanoid toy can be given better support by using the larger area of ​​the support plate to make static support contact with the ground when it is standing still, so that the humanoid toy can stand stably.

[0022] (2) By rotating the support plate to the same height as the lower edge of the front wheel, the humanoid toy can be better supported by the large area of ​​the support plate sliding with the ground when it moves, so that the humanoid toy can move smoothly at a slower speed.

[0023] (3) This application allows the humanoid toy to move at a faster speed by rotating the support plate so that its lowest end is higher than the lower edge of the front wheel.

[0024] (4) The front end of the bottom of the support plate of this application is set as an inclined surface. The uneven parts of the splicing plate are gradually squeezed and flattened by the inclined surface, so that the human-shaped toy can pass through the uneven splicing parts of multiple soft splicing plates.

[0032] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

[0033] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "front," "rear," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. The phrase "two components obtain an integrated structure through an integral molding process" means that during the formation of one of the two components, that component is connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connection, or screw connection) to connect the two components together.

[0034] Please refer to Figure 1 A humanoid toy foot structure includes a rear wheel 1 and two front wheels 2, the front wheels 2 having the same diameter. The rear wheel 1 is located at the rear end of the foot, the axes of the front wheels 2 and the rear wheel 1 are parallel, and the front wheels 2 are spaced apart in front of the rear wheel 1, serving as the front end of the foot.

[0035] In this design, connecting parts 4 are provided on both sides of the rear wheel 1 and the corresponding front wheels 2, thereby connecting the rear wheel 1 and the two front wheels 2 to form a roughly foot-like area. This foot-like area, constructed from one rear wheel and two front wheels, conforms to the shape of a human foot, where the front end is wider than the rear end. The bottoms of the rear wheel 1 and the front wheels 2 serve as the soles of the toy's feet. However, this application does not preclude the possibility of using two rear wheels, with a connection similar to that of a single rear wheel, which will not be described in detail here.

[0036] The connection between the legs and feet of the humanoid toy can be, for example, a ball joint or a plug-in connection; specific structures will not be described here. Additionally, decorative pieces can be inserted into the connecting part 4 to better conform to the shape of the feet. The decorative pieces and the connecting part can use a tongue-and-groove interlocking structure, which will not be detailed here.

[0037] Specifically, one end of the rear wheel 1 is rotatably connected to the rear end of a connecting part 4, the same end of a front wheel 2 is rotatably connected to the front end of the connecting part 4, the other end of the rear wheel 1 is rotatably connected to the rear end of another connecting part 4, and the same end of another front wheel 2 is rotatably connected to the front end of the connecting part 4.

[0038] like Figure 1In this design, at one end of the rear wheel 1, the rear end of the connecting part 4 is integrally formed with a first connecting shaft 41, which passes through the axle of the rear wheel 1 and forms a rotatable connection with the rear wheel 1. The front end of the connecting part 4 is integrally formed with a second connecting shaft 42, which passes through the axle of the front wheel 2 and is rotatably connected with the front wheel 2. Similarly, at the other end of the rear wheel 1, the first connecting shaft and the second connecting shaft of another connecting part 4 are rotatably connected to the rear wheel and a front wheel, respectively. To limit the axial movement of the rear and front wheels, shoulders can be provided on the first and second connecting shafts; this is a conventional design, and the specific structure is omitted here. Alternatively, the ends of the first connecting shafts 41 of the two connecting parts 4 can be inserted together, and the ends of the second connecting shafts 42 of the two connecting parts 4 can be inserted together.

[0039] In some embodiments, the diameter of the rear wheel 1 can be larger than that of the front wheel 2, thereby facilitating the installation of a drive motor (not shown) on the rear wheel 1. The output shaft of the drive motor is connected to the axis of the rear wheel 1, driving the rear wheel 1 to rotate, thus enabling the entire humanoid toy to move. Specifically, the housing of the drive motor can be fixedly connected to the connecting part 4, for example, fixedly connected to the first connecting shaft. The output shaft of the drive motor is connected to the axis of the rear wheel 1, thereby driving the rear wheel 1 to rotate. During the rotation of the rear wheel 1, the humanoid toy moves automatically, while the front wheel 2 rotates passively. However, a drive motor is not necessary; it is also possible to omit the drive motor and instead allow the humanoid toy to move manually.

[0040] A support plate 3 is rotatably connected between the two front wheels 2. A third connecting shaft 31 is fixedly connected to the support plate 3. Specifically, a connecting block is fixedly connected to the upper end of the support plate 3, and a third connecting shaft 31 is fixedly connected to both ends of the connecting block. The third connecting shaft 31 is used to be rotatably inserted into the axle of the front wheel 2, so that the support plate 3 can rotate relative to the front wheel 2.

[0041] The support plate 3 is rotatably switchable between a first position and a second position. A first limiting block 33 is fixedly connected to the rear end of the support plate 3, and the first limiting block 33 protrudes from the support plate 3. The first limiting block 33 is used when the support plate 3 rotates to the point where its bottom surface is at the same height as the lower edge of the front wheel 2 (i.e., the first position), such as... Figure 2 As shown in (a), the first limiting block 33 abuts against the connecting part 4, for example, against a certain part on the lower side of the connecting part 3, thereby restricting the support plate 3 from continuing to rotate, so that the support plate 3 is kept at the same height as the lower edge of the front wheel 2. When the support plate 3 is in the first position, because the bottom area of ​​the support plate 3 is large, it can provide more stable support for the feet, so that when the humanoid toy stands, it can be reliably stood even on a relatively smooth surface.

[0042] It should be noted that the bottom surface of the first support plate in this application is only level with the lower edge of the front wheel 2, and does not support it under the front wheel. Therefore, even when the support plate 3 is in the first position, the humanoid toy can still move under the drive of the drive motor or under the action of manual pushing force. Especially on relatively smooth ground, the support plate 3 can provide a certain degree of stable support for the humanoid toy while it moves.

[0043] In addition, the surface area of ​​the support plate can be set according to actual needs, so that it can provide good support without completely hindering the movement of the humanoid toy.

[0044] A second limiting block 32 is fixedly connected to the front end of the support plate 3. The second limiting block 32 is used to prevent the support plate 3 from rotating to a position where its lowest point is higher than the lower edge of the front wheel 2 (i.e., the second position). Figure 2 As shown in (b), the second limiting block 32 abuts against the connecting part 4, for example, against a certain part on the upper side of the connecting part 4, thereby restricting the support plate 3 from continuing to rotate, so that the support plate 3 remains above the front wheel 2. When the support plate 3 is in the second position, the overall height of the support plate 3 is higher than the lower edge of the front wheel, so it will not contact the plane on which the foot stands. Therefore, under the action of the rear wheel drive motor or under the action of manual pushing force, the foot can move smoothly by the rolling of the rear wheel and the front wheel.

[0045] Furthermore, the first limiting block 33 of the support plate 3 extends to the left and right sides beyond the front wheel 2 from the rear end of the support plate 3. This allows the first limiting block 33 to contact and limit a certain part of the outer side of the connecting part 4.

[0046] In some embodiments, the first limiting block 33 and the second limiting block 32 may be integrally formed with the support plate 3, or may be detachably installed on the support plate 3 by means of fasteners, or may be installed on the support plate 3 by means of snap-fit ​​connection, adhesive bonding, etc.

[0047] In some embodiments, the bottom of the support plate 3 may have anti-slip textures to help the humanoid toy stand more stably.

[0048] In some embodiments, the humanoid toy can move smoothly on a smooth surface, but if it moves on a mat made of multiple soft interlocking panels 5, such as foam boards or soft plastic boards, some joints may be raised, such as... Figure 3As shown, on such a mat, a human-shaped toy might have difficulty passing through or might fall over. Therefore, the bottom surface of the support plate 3 in this application can have a V-shaped cross-section in the front-to-back direction, with the included angle of the V-shape between 165° and 175°, thus creating a slope at its front bottom. Alternatively, the front end of the bottom surface of the support plate 3 can be a slope that gradually decreases from front to back, while the rear end remains flat. During the movement of the human-shaped toy, the slope can gradually press down on the raised areas, making the mat as flat as possible. This allows the human-shaped toy to pass through the joints more easily, and after passing through the joints, the flat surface at the rear end of the support plate 3 provides good support for the human-shaped toy, ensuring its stability during movement.

[0049] like Figure 4 In the diagram, (a) shows the inclined surface at the front end of the support plate 3 about to contact the raised part; (b) shows the state where the inclined surface at the front end of the support plate 3 is pressing down on the raised part; and (c) shows the state of the foot structure after the inclined surface at the front end of the support plate 3 has flattened the raised part, at the joint of the soft splicing plate 5. It is evident that the inclined surface at the front end helps the foot structure to connect to the raised part, providing a better experience for the player.

[0050] It should be noted that since a certain amount of pressure is required to squeeze the raised part, it may not be very effective for small, lightweight humanoid toys, but it can have a better passage effect for large, heavy humanoid toys.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
