However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0055] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0056] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0057] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0058] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0059] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

[0063] Example 1

[0064] This application provides a metal frame human figure structure, on which decorative fabric is decorated, allowing it to be used as a toy; especially for use during festivals or performances, it can enhance the toy's fun or artistic value. The following is in conjunction with... Figures 1-8 This application provides a detailed description of a steel frame structure for human figures.

[0065] The iron frame structure includes a head 1, arms 2, support components 3, and drive components 4; the structure of the head 1, arms 2, support components 3, and drive components 4, as well as the position and connection relationship between each component, are described in detail below.

[0066] The head 1 is disposed on the support component 3 and extends along the first direction 5. Combined Figure 1 As shown, and in accordance with Figure 1 Taking the angle shown as an example, the first direction 5 mentioned above refers to a direction that forms an angle of approximately 2°-15° with the vertical upward (preferably 4°). In practical applications, a head cover, shell, or head covering can be used to decorate the head 1 to serve as or simulate the head of a toy.

[0067] There are two arms 2, each positioned at one end of the support assembly 3 along the second direction 6. This is still a combination. Figure 1 As shown, and in accordance with Figure 1 Taking the angle shown as an example, the second direction 6 refers to the length direction of the support component 3, that is, the two arms 2 are respectively set at both ends of the support component 3 along its length direction. In actual applications, decorative shells or decorative fabrics can be used on the two arms 2 to act as or simulate the arms of a toy.

[0068] Additionally, to enhance the festive atmosphere of the toy, one arm 2 extends at a predetermined angle to the first direction 5, while the other arm 2 extends downwards. Figure 1 As shown, the left arm 2 extends downwards, and the right arm 2 extends in a direction at a preset angle to the first direction 5; it can be understood that the left arm 2 is in a naturally drooping state, and the right arm 2 is in a state of being stretched upwards.

[0069] The drive assembly 4 is disposed on the support assembly 3; the drive assembly 4 includes a drive unit 401 and a transmission unit 405 connected to the output end of the drive unit 401 via a crank 402. Specifically, in combination with Figure 2 and Figure 4As shown, the drive unit 401 includes a drive motor 411 and a reducer 412; the output shaft 413 of the drive motor 411 is fixedly connected to the input shaft of the reducer 412 via a pulley, and the flange connection method is simple to install. This also improves the connection stability between the reducer 412 and the drive motor 411. The output shaft 413 of the reducer 412 is rigidly connected to the crank 402 shaft by welding. Furthermore, in conjunction with... Figure 2 and Figure 8 As shown, the crank 402 includes a first section 403 and a second section 404 that is perpendicularly connected to the first section 403. In addition, the end of the first section 403 facing away from the second section 404 is perpendicularly connected to the output shaft 413 of the reducer 412, and the end of the second section 404 facing away from the first section 403 is connected to the first transmission rod 406 (the first transmission rod 406 is described in detail below).

[0070] Specifically, combined Figure 2 and Figure 4 As shown, the transmission part 405 is sequentially connected to the head 1 and the arm part 2 extending at a preset angle to the first direction. The transmission part 405 includes a first transmission rod 406, a second transmission rod 407, a third transmission rod 408, a fourth transmission rod 409, and a fifth transmission rod 410. The second transmission rod 407 and the third transmission rod 408 are angled together on the head 1. Further, the second transmission rod 407 and the third transmission rod 408 each include a main rod and a bent rod. The main rods of the second transmission rod 407 and the third transmission rod 408 are angled together on the head 1, and the axes of the main rods of the second transmission rod 407 and the third transmission rod 408 are perpendicular to the head 1. The end of the main rod of the second transmission rod 407 facing away from the head 1 extends vertically upward to form a bent rod, and the end of the main rod of the third transmission rod 408 facing away from the head 1 also extends vertically upward to form a bent rod. Furthermore, the fifth transmission rod 410 is disposed on the arm portion 2 extending at a predetermined angle to the first direction 5; similarly, the fifth transmission rod 410 also includes a main rod and a bent rod, wherein the main rod of the fifth transmission rod 410 is connected to the arm portion 2 extending at a predetermined angle to the first direction 5, and its axis is perpendicular to the axis of the arm portion 2 extending at a predetermined angle to the first direction 5. In addition, the end of the main rod of the fifth transmission rod 410 away from the arm portion 2 extends vertically upward to form a bent rod. Furthermore, the two ends of the first transmission rod 406 are respectively hinged to the second section of the crank 402 and the bent portion of the second transmission rod 407; the two ends of the fourth transmission rod 409 are respectively hinged to the bent portion of the third transmission rod 408 and the bent portion of the fifth transmission rod 410.

[0071] It should also be noted that the angle between the axis of the second transmission rod 407 and the axis of the third transmission rod 408 is between 25° and 50°. Preferably, the angle between the axis of the second transmission rod 407 and the axis of the third transmission rod 408 is 30°.

[0072] In actual use: when the drive unit 401 drives the crank 402 to rotate, the head 1 can rotate via the first transmission rod 406 and the second transmission rod 407; when the head 1 rotates, the arms 2 can rotate via the third transmission rod 408, the fourth transmission rod 409, and the fifth transmission rod 410. In this way, when some doll decorations are placed on the head 1 and arms 2, the head and arms can move, satisfying the needs of some festive occasions and increasing the toy's fun.

[0073] Further explanation: Assume the initial state is Figure 1 and Figure 2 The state shown is such that the drive assembly 4 is located at the left end of the head 1, and the arm 2, extending at a preset angle to the first direction 5, is located at the right end of the head 1; the first segment 403 of the crank 402 is parallel to the second direction 6, and the second segment 404 of the crank 402 is close to the head 1. Therefore, when the drive motor 411 starts, the first segment 403 of the crank 402... Figure 2 The crank 402 rotates counterclockwise in the direction shown. Similarly, the second section 404 of the crank 402 will also rotate counterclockwise. When the crank 402 rotates counterclockwise, it will pull the first transmission rod 406 to the right. When the first transmission rod 406 moves to the right, since the first transmission rod 406 and the second transmission rod 407 are hinged, and since the second transmission rod 407 is fixedly connected to the head 1, it will drive the head 1 to rotate counterclockwise. So when the head 1 is decorated with ornaments to serve as the head of the toy, the toy's head can be rotated counterclockwise. Next, when the head 1 rotates counterclockwise, it will drive the third transmission rod 408 to rotate counterclockwise. Since the third transmission rod 408 and the fourth transmission rod 409 are hinged, the fourth transmission rod 409 will also be pulled to the right. When the fourth transmission rod 409 is pulled to the right, since the fourth transmission rod 409 and the fifth transmission rod 410 are hinged, the fifth transmission rod 410 will be driven to rotate clockwise. Therefore, when the arm 2 is decorated with ornaments to act as the toy's arm, the toy's arm can be rotated clockwise.

[0074] If the initial state is Figures 3-8The state shown is such that the drive assembly 4 is located at the right end of the head 1, and the arm 2, extending at a preset angle to the first direction 5, is located at the left end of the head 1; the first segment 403 of the crank 402 is parallel to the second direction 6, and the second segment 404 of the crank 402 is away from the head 1. Therefore, when the drive motor 411 starts, the first segment 403 of the crank 402... Figure 4 The crank 402 rotates counterclockwise in the direction shown in the diagram. Similarly, the second section 404 of the crank 402 will also rotate counterclockwise. When the crank 402 rotates counterclockwise, it will pull the first transmission rod 406 to the left. When the first transmission rod 406 moves to the left, since the first transmission rod 406 and the second transmission rod 407 are hinged, and since the second transmission rod 407 is fixedly connected to the head 1, it will drive the head 1 to rotate clockwise. Therefore, when the head 1 is decorated with ornaments to serve as the head of the toy, the toy's head can be rotated clockwise. Next, when the head 1 rotates clockwise, it will cause the third transmission rod 408 to rotate clockwise. Since the third transmission rod 408 and the fourth transmission rod 409 are hinged, the fourth transmission rod 409 will also be pushed to the left. When the fourth transmission rod 409 is pushed to the left, since the fourth transmission rod 409 and the fifth transmission rod 410 are hinged, the fifth transmission rod 410 will be driven to rotate counterclockwise. Therefore, when the arm 2 is decorated with ornaments to act as the toy's arm, the toy's arm can be made to rotate counterclockwise.

[0075] The above is from Figure 1 and Figure 2 The state rotates to Figures 3-8 In this state, it completes a unidirectional rotation (oscillation or rotation); when by Figures 3-8 The state rotates to Figure 1 and Figure 2 In this state, it completes another unidirectional rotation (oscillation or rotation) in the opposite direction.

[0076] It is worth noting that the clockwise or counterclockwise rotation of the head 1 and arm 2 mentioned above is not a full rotation, but a rotation of about 75°, which can also be described as left and right rotation or swinging, that is, the head 1 and arm 2 can rotate and swing back and forth.

[0077] In summary, this application enables the head 1 and arm 2 to rotate (spin or swing) via the transmission part 405 within the drive assembly 4. When decorative fabric is added to the head 1 and arm 2, it can be used as a toy, enhancing its fun or artistic appeal during festivals or performances. Furthermore, the fact that both parts can be driven by a single drive assembly 4 significantly reduces costs.

[0078] In this embodiment, combined with Figure 4As shown, the support assembly 3 includes a support plate 301 and a support ring 302. The support ring 302 has an elliptical ring structure. The support plate 301 is plate-shaped, extending along the second direction 6, and its two ends along the second direction 6 are respectively fixed to the support ring 302. Furthermore, a head fixing position for fixing the head 1 is formed at the center of the support plate 301, and an arm fixing position for fixing the arm 2 is formed at the end of the support plate 301 along the second direction 6. The head fixing position and arm fixing position refer to mounting areas formed on the support plate 301.

[0079] The aforementioned support assembly 3 also includes a support rod 303; the support rod 303 is an arc-shaped plate that spans across the support plate 301 along its width direction and is connected to the support ring 302. Furthermore, multiple support rods 303 are provided, and these multiple support rods 303 are arranged at intervals along the second direction 6, such that the multiple support rods 303 are raised relative to the support ring 302. When decorative ornaments are attached to the support rods 303, they can serve as the shoulders of a toy.

[0080] In this embodiment, combined with Figure 6 As shown, the head 1 includes a first sleeve 101 and a first rotating shaft; the first rotating shaft is fixed at the head fixing position and extends along the first direction 5, and the first sleeve 101 is sleeved on the first rotating shaft and can rotate around the first rotating shaft. That is, when the drive unit 401 is started, the transmission unit 405 can drive the first sleeve 101 to swing back and forth.

[0081] Furthermore, the head 1 also includes a turntable 102, which is located on top of the first sleeve 101 and serves to support the decorative cloth.

[0082] In this embodiment, combined with Figure 6 As shown, the arm part 2 includes a second sleeve 201 and a second rotating shaft; the second rotating shaft is fixed to the arm fixing position and extends in a direction at a preset angle to the first direction 5, the second sleeve 201 is sleeved on the second rotating shaft and can rotate around the second rotating shaft. That is, when the drive unit 401 is started, the transmission unit 405 can drive the second sleeve 201 to swing back and forth.

[0083] In this embodiment, combined with Figure 1 As shown, the iron frame structure also includes a body part 7; the body part 7 includes a body support frame 701 and a chassis 706; one end of the body part 706 is connected to the support plate 301 in the vertical direction, and the other end is connected to the chassis 706.

[0084] Specifically, the body support frame 701 has a frame structure; the body support frame 701 includes support legs 702 and connecting rods 705; wherein two support legs 702 are provided, and the two support legs 702 are respectively connected to the two ends of the support ring 302 along the second direction 6. The connecting rods 705 extend along the second direction 6, and their two ends are respectively connected to the two support legs 702. The two support legs 702 can act as legs to support the support plate 301; the connecting rods 705 connect the two support legs 702, which can improve the support stability of the body part 7 to a certain extent.

[0085] Specifically, the chassis 706 includes a base frame 703 and support rods 704; the base frame 703 has a frame structure, and two support rods 704 are provided, spaced apart from each other on the base frame 703; the ends of two support legs 702 facing away from the support ring 302 are connected to the support rods 704. Further, the dimensions of the chassis 706 are larger than the dimensions of the support ring 302, essentially representing a human foot in the toy; it provides stable support for the body 7.

[0086] In this embodiment, combined with Figure 6 As shown, the support plate 301 is not a straight plate, but includes a first plate segment and a second plate segment, which are connected at an angle. The head 1 is located on the first plate segment, and the arm 2 is located on the second plate segment. Since the first plate segment and the second plate segment are connected at an angle, when the head 1 extends along the first direction 5, the arm 2 extends along a direction that is at a preset angle to the first direction 6. The preset angle is preferably 2°-10°.

In actual use, decorative fabric can be added to the head, arms, and body of the iron frame humanoid structure to make it function as a toy that simulates a human. When the head and arms are rotated, the toy's fun factor can be increased, and the atmosphere can be enhanced during festivals or performances.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
