Description

Technical Field

[0001] This disclosure relates to the field of detachable toy technology, and more specifically, to a building block structure. Background Technology

[0002] In the world of building block toys, most scenes of buildings, vehicles, and plants can be recreated using bricks and specially shaped building blocks. While it's also possible to recreate people and animals, building block figures and animals assembled from regular building blocks are limited by the lines of those regular blocks, making it difficult to capture the beauty and unique lines of people and animals. Currently, there are some redesigned building block animals, but these animals have the following problems: The pose is limited and can only meet the needs of one scenario. If other scenarios require different poses, the design must be completely redesigned, resulting in huge design and production costs. Utility Model Content

[0097] In the accompanying drawings, the dimensions of all components are shown only to illustrate their relative positions; the relative sizes of the components do not represent their actual dimensions or proportions.

[0098] This disclosure provides a modular structure 1000, such as Figures 1a-1h As shown, the device includes a head 100 and a body 200. The head 100 has a first connecting hole 110, and the body 200 has a first connecting portion 210. The cross-section of the first connecting portion 210 is circular, and the cross-section of the first connecting hole 110 is adapted to the shape of the cross-section of the first connecting portion 210. The head 100 and the body 200 are detachably connected by inserting the first connecting portion 210 into the first connecting hole 110. That is, the user can connect the head 100 and the body 200 by inserting the first connecting portion 210 into the first connecting hole 110. When the user needs to disassemble the building block structure 1000, the first connecting portion 210 can be removed from the first connecting hole 110, thus separating the head 100 from the body 200. Secondly, since the cross-section of the first connecting part 210 is circular, and the cross-section of the first connecting hole 110 is adapted to the cross-sectional shape of the first connecting part 210, the head 100 can rotate relative to the first connecting part 210 through the first connecting hole 110, thereby realizing the rotation of the head 100 relative to the main body 200, so as to achieve the effect of adjusting the posture of the head 100 of the block structure 1000.

[0099] Furthermore, a first connecting groove 220 is formed on the bottom surface 230 of the main body or the bottom surface of the head 100. The external building blocks 2000 are connected via the first connecting groove 220, allowing the building block structure 1000 to be fixed to the external first building block connecting part 2100. The main body 200 can also adjust the rotation angle of the first connecting groove 220 relative to the first building block connecting part 2100, thereby adjusting the orientation of the building block structure 1000 relative to the external first building block connecting part 2100, further improving the posture of the building block structure 1000 to meet requirements and enhance playability. When the raw materials for the head 100 and the main body 200 are of different colors, the color spraying of the building block structure 1000 can be reduced, lowering printing costs.

[0100] Therefore, the block structure 1000 disclosed herein can independently produce the head 100 and the main body 200. The head 100 and the main body 200 can also be customized with relative posture adjustments, which can meet the usage needs of various scenarios, reduce design and production costs, and improve the user's free creative experience.

[0101] Specifically, in some embodiments, such as Figure 1a and Figure 1b As shown, a first block connecting portion 2100 is formed on the block 2000. The first block connecting portion 2100 can be a cylinder with a diameter of 4.8 mm and a height of 1.7 mm. Therefore, other blocks 2000 can be detachably connected to the bottom surface 230 of the main body by engaging with the first connecting groove 220 through the first block connecting portion 2100.

[0102] In some embodiments, the shape of the building block structure 1000 is an animal shape, or the shape of the building block structure 1000 is roughly an animal shape, as shown in Figures 1-10. The shape of the building block structure 1000 can be a chicken, fish, bear, dog, pig, pigeon, squirrel, cat, owl, etc. The head 100 of the building block structure 1000 can be the head 100 of an animal, and can have facial features such as ears, mouth, and nose. The body 200 of the building block structure 1000 can be the body of an animal, and can have limbs and a torso, etc., but this disclosure does not limit this.

[0103] In some embodiments, such as Figure 1hAs shown, the diameter 211 of the first connecting portion is a first dimension, the axial extension length 212 of the first connecting portion is a first dimension, and the inner diameter 111 of the first connecting hole is a first dimension. Specifically, the first connecting portion 210 is a rod-shaped structure with a circular cross-section, and the diameter of the cross-section is the first dimension. In some embodiments, the first connecting portion 210 extends along its axial direction N by a distance of the first dimension, which is the length of the first connecting portion 210, such that both the radial diameter and axial length of the first connecting portion 210 are the first dimensions, in order to adapt to heads 100 of different sizes. In order for the first connecting portion 210 to be smoothly inserted into the first connecting hole 110, the inner diameter 111 of the first connecting hole can be the first dimension or larger than the first dimension. The cross-section of the first connecting hole 110 can be polygonal or circular, with a diameter of the first dimension, which matches the size of the first connecting portion 210. Specifically, the first dimension is 3.2 mm ± 10%. Given the aforementioned dimensions, the first connecting part 210 occupies a small volume while maintaining sufficient connection strength, allowing it to adapt to different sizes of heads 100. This enables different heads 100 to be freely inserted into the main body 200 of different building block structures 1000. When the cross-section of the first connecting hole 110 is polygonal, it ensures that the first connecting part 210 can be inserted into the first connecting hole 110, and also provides accommodating space between the wall of the first connecting hole 110 and the side of the first connecting part 210. This allows for atmospheric pressure balance when the first connecting part 210 is inserted into the first connecting hole 110, facilitating insertion and disassembly.

[0104] For ease of understanding, this disclosure is as follows: Figure 2h Draw the axial direction N of the first connection.

[0105] In some embodiments, the first dimension is 3.2 mm ± 10%. In some embodiments, the first dimension is 3.2 mm to accommodate the dimensions of conventional building block parts.

[0106] Alternatively, in other embodiments, the width 221 of the first connecting groove is a second dimension, and the ratio of the first dimension to the second dimension is A. ≤A≤ In some embodiments, A is In this case, the first dimension is 3.0 mm, and the second dimension is 5.0 mm; in some embodiments, A is... When the first dimension is 3.2mm and the second dimension is 4.8mm; in some embodiments, A is... At that time, the first dimension was 3.4mm and the second dimension was 4.6mm.

[0107] Alternatively, the first dimension is 3.2mm ± 10%, and the ratio of the first dimension to the second dimension is A. ≤A≤ In some embodiments, A is .

[0108] Considering that plastics with different material ratios have different elasticity and hardness, the comparison value A, the first dimension and the second dimension in this embodiment are limited in range and different values ​​are selected to adapt to building block structures 1000 with different elasticity and hardness.

[0109] In some embodiments, the first connecting hole 110 is recessed inward from the first connecting surface 120 of the head 100, and the first connecting portion 210 protrudes outward from the second connecting surface 219 of the body 200. The outer contour of both the first connecting surface 120 and the second connecting surface 219 is circular. In some embodiments, the outer contours of the first connecting surface 120 and the second connecting surface 219 are the same. This solution can be understood as making the connecting surfaces of the animal's "head 100" and "body" (i.e., the body 200) circular, so that when the animal's head rotates relative to the body, the outer contours of the "head 100" and the "body" remain connected, avoiding "meat separation" and improving consistency.

[0110] Because different animals have different sizes for their "head 100" or "neck" and "body," in some embodiments, the diameter 121 of the outer contour of the first connecting surface can be a second, third, fourth, or fifth size depending on the building block structure 1000, wherein the second, third, fourth, and fifth sizes are all different. In some embodiments, the second size is 4.8 mm, the third size is 6.4 mm, the fourth size is 7.8 mm, and the fifth size is 15.8 mm. In some embodiments, ① the diameter of the miniature neck is 4.8 mm, corresponding to the size of the building block connecting cylinder (such as the first building block connecting part 2100); ② the diameter of the small neck is 6.4 mm, corresponding to the size of the partition at the bottom of the building block, and also corresponding to the bottom outer dimension of the 1x1 building block round part (such as the foot 282); ③ the diameter of the medium neck is 7.8 mm, corresponding to the size of the 1x1 building block wooden part (such as the foot 282). Figure 2d The width of the 500 block also corresponds to the outermost dimension of a 1x1 round block part (such as the foot 282); ④ The diameter of the large neck is 15.8mm, corresponding to a 2-block block part (such as... Figure 10l The length dimension of the particleboard (600). Optionally, the diameter of the outer contour of the first connecting surface, 121, can also be 8mm, which is the fourth dimension plus the number of blocks. For example, 7.8 (1 block width) + 2 (2 extra blocks) * 8 = 33.8mm is the width of 3 blocks.

[0111] In some embodiments, the ratio of the second dimension to the third dimension is B, the ratio of the third dimension to the fourth dimension is C, and the ratio of the fourth dimension to the fifth dimension is D; wherein, ≤B≤ , ≤C≤ , ≤D≤ .

[0112] In some embodiments, B is At this point, the second dimension is 4.8mm and the third dimension is 6.4mm.

[0113] In some embodiments, C is At this point, the third dimension is 6.4mm and the third dimension is 7.8mm.

[0114] In some embodiments, D is At this point, the third dimension is 7.8mm and the fourth dimension is 15.8mm.

[0115] In some embodiments, the head 100 and body of different sizes can be interchanged. For example, a head 100 having a first connecting surface 120 of a third size can be mounted onto a body 200 having a second connecting surface 219 of a second size. It should be noted that since each size of head 100 has a first connecting hole 110 and each size of body 200 has a first connecting portion 210, and the sizes of the first connecting hole 110 and the first connecting portion 210 can be kept consistent, the head 100 and body 200 can be replaced according to user preference.

[0116] In some embodiments, a slot 250 is formed on the top surface of the main body 200, and a second connecting portion 251 is formed at the bottom of the slot 250. The cross-section of the second connecting portion 251 is circular, and the diameter 252 of the cross-section of the second connecting portion is a second dimension, which is different from the first dimension. The height 253 of the second connecting portion is a sixth dimension. It should be noted that in some embodiments, the shape of the building block structure 1000 is an animal or roughly an animal, so the top surface of the main body 200 can correspond to the "back" of the "animal".

[0117] Specifically, the size of the slot 250 can match that of the building board 500. The building board 500 can be a smooth panel or a particle board 600 with connecting building blocks. When the building board 500 is a smooth panel, refer to... Figure 10nThe animal's back is flat, reducing any abruptness. When the building board 500 is a particleboard 600, other building blocks 2000 can be connected via the particleboard 600, allowing for scenes of animals carrying objects or small animals resting on larger animals. It should be noted that the particleboard 600 refers to the building board 500 with a second building block connecting portion 620 for connection with other building blocks 2000. In some embodiments, the particleboard 600 can be considered as one of the other building blocks 2000, and the second building block connecting portion 620 of the particleboard 600 is the first building block connecting portion 2100. In some embodiments, the first building block connecting portion 2100 and the second building block connecting portion 620 are cylinders with a diameter of 4.8mm to 4.9mm and a height of 1.7mm to 1.9mm. Furthermore, the second connecting portion 251 can also serve as a block connecting portion. In some embodiments, the second connecting portion 251 is a cylinder with a diameter of 4.8mm to 4.9mm and a height of 1.7mm to 1.9mm. In some embodiments, the second dimension is 4.9mm and the sixth dimension is 1.8mm. When the diameter of the second connecting portion 251 is 4.9mm and the corresponding connecting groove (block connecting groove 510 or particleboard connecting groove 610) is 4.8mm, the elastic deformation of the second connecting portion 251 allows it to be inserted into the block connecting groove and held in place, thereby improving the connection strength.

[0118] It should be noted that the bottom of the building board 500 has a building board connecting groove 510 for engaging with the second connecting part 251. The bottom of the particle board 600 has a particle board connecting groove 610 for engaging with the second connecting part 251. Furthermore, the top of the particle board may have a second building block connecting part 620 for connecting with other building blocks 2000. The second building block connecting part 620 may be a cylinder with a diameter of 4.8mm to 4.9mm and a height of 1.7mm to 1.9mm.

[0119] In some embodiments, the width of the body 200 is one grid width, and the edges of the card slots 250 on the body 200 are designed to smoothly transition to the left and right sides of the body 200, such as... Figure 2h As shown, the edges of the slot 250 form an open design on the left and right sides of the main body 200, meaning that the left and right sides of the slot 250 can communicate with the outside world and are not obstructed by the main body 200. This allows users to directly contact the building blocks from the left and right sides of their body for quick disassembly of the building board 500. It should be noted that the width of one segment is 7.6-8.2mm; in some embodiments, the width of one segment is 7.8mm. That is, the width of the main body 200 can be 7.8mm.

[0120] In some embodiments, the main body 200 includes a first part 213 and a second part 214, which are detachably connected. For a main body 200 with a complex shape, the detachable first part 213 and the second part 214 can be manufactured separately to reduce production and design difficulties. Meanwhile, the independent first part 213 and the second part 214 can also be assembled with external building block 2000 parts to form a new main body 200, providing more building block structure 1000 shapes.

[0121] In some embodiments, the slot 250 includes a first slot portion 254 and a second slot portion 255, where the first slot portion 254 is located in the first portion 213 and the second slot portion 255 is located in the second portion 214. Specifically, for a block structure 1000 with a width of two blocks or more in the main body 200, the main body 200 can be split into the first portion 213 and the second portion 214, and the slot 250 is also split accordingly. Specifically, the slot 250 includes a first area and a second area, where the first area is located in the first portion 213 of the main body 200 and the second area is located in the second portion 214 of the main body 200. Therefore, when the main body 200 is split into the first portion 213 and the second portion 214, the slot 250 is also split. The above solution facilitates the removal of the block board 500 from the split main body 200, avoiding the situation where the surface of the block board 500 is flush with the back of the main body 200 and surrounds the block board 500 after installation, making it impossible to remove the block board 500. It should be noted that if the first and second zones can be slot-shaped structures, then the first zone is not shown in the diagram. If, after the card slot is disassembled, the individual parts cannot function as slots, this is also within the scope of protection of this disclosure.

[0122] In some embodiments, the separation of the card slot 250 can be achieved by cutting along the connecting edge between the side and the bottom surface, such as... Figure 10e and Figure 10f The first part 213 and the second part 214 are separated. The surface of the mounting protrusion 2141 in the second part 214 becomes the bottom surface of the slot 250, and the wall of the mounting through hole 2131 in the first part 213 becomes the side surface of the slot 250. Alternatively, the slot 250 can be separated by generating separation lines on the bottom and side surfaces respectively, dividing the slot 250 into two sub-slots, each with a portion of the bottom surface and a portion of the side surface. (See reference...) Figure 11a and Figure 11b The first portion 213 and the second portion 214 each include a portion of the side surface and a portion of the bottom surface of the card slot 250. In some embodiments, such as Figure 11a and Figure 11bAs shown, the first connecting portion 210 is disposed on either the first part 213 or the second part 214. That is, when the main body 200 can be divided into multiple sub-parts (e.g., the first part 213, the second part 214), the first connecting portion 210 can be located on one of the sub-parts, avoiding the impact on connection strength caused by splitting the first connecting portion 210. The splitting of the main body 200 can be horizontal or vertical. In some embodiments, such as... Figures 10a-10h As shown, the main body 200 includes a first part 213, a second part 214, and a third part 217. The first part 213 can be mounted on the second part 214. The second part 214 has three mounting protrusions 2141, and the first part 213 has a mounting groove 2132. The mounting groove 2132 engages with one of the mounting protrusions 2141 of the second part 214, allowing the first part 213 to snap into place with the second part 214. Furthermore, the first part 213 has a mounting through hole 2131, and the remaining two mounting protrusions 2141 of the second part 214 can be located within this mounting through hole 2131. The third part 217 can be mounted on two mounting protrusions 2141, allowing it to be installed within the mounting through hole 2131. Additionally, the third part 217 has two mounting protrusions 2141 forming a connecting part for connecting with the building board 500 and the particle board 600. The slot 250 is formed by the cooperation of the first part 213, the second part 214, and the third part 217. The side wall of the mounting through hole 2132 of the first part 213 serves as the side of the slot 250, while parts of the second part 214 and the third part 217 can serve as the bottom surface of the slot 250.

[0123] In some embodiments, the first connecting groove 220 is recessed inward to form a fourth connecting hole 222, the fourth connecting hole 222 having a circular cross-section and a diameter of a first dimension. Specifically, the bottom of the first connecting groove 220 is recessed inward to form the fourth connecting hole 222, and the shape and size of the cross-section of the fourth connecting hole 222 match the first connecting portion 210, so the first connecting portion 210 can also be inserted into the fourth connecting hole 222. Of course, a first-dimensional building block 2000 part can also be inserted into the fourth connecting hole 222 to mount the body 200 or the head 100 onto the building block 2000 part having the first dimension. In some embodiments, the first connecting groove 220 is a cylindrical groove, and the inner surface of the first connecting groove 220 can be recessed inward to form the fourth connecting hole 222. In some embodiments, the inner surface of the first connecting groove 220 is the top surface of the first connecting groove 220.

[0124] It should be noted that in some embodiments, the first connecting groove 220 is located at the bottom of the main body 200 with its opening facing downwards. Therefore, the bottom of the groove is located on the top surface of the first connecting groove 220. Consequently, the fourth connecting hole 222 should extend upwards from the top surface of the first connecting groove 220 to form this. Furthermore, in some embodiments, due to the design of the fourth connecting hole 222, the block structure 1000 can connect to other structures (other blocks with the first connecting portion 210) to represent more animal scenes and forms.

[0125] In some embodiments, such as Figures 4a-4e As shown, the main body 200 includes a body portion 281 and feet 282. The first connecting groove 220 can be located on the bottom surface of the body portion 281 or on the bottom surface of the feet 282, depending on the specific building block structure 1000. Specifically, when the main body 200 of some building block structures 1000 does not have feet 282, the first connecting groove 220 can be located on the main body 200. Furthermore, other building block structures 1000 can be installed on the first connecting groove 220 of the main body 200 to serve as feet 282. When the injection molding materials of the head 100, the main body 200, and other building block structures 1000 are of different colors, the color spraying of the building block structures 1000 can be reduced, lowering printing costs.

[0126] For example, a 1000-block structure shaped like a seagull, such as... Figures 3a-3h As shown, the main body 200 includes a body portion 281 and a foot portion 282. The bottom surface 230 of the main body is the bottom surface of the foot portion 282, and a first connecting groove 220 is provided on the foot portion 282. In some embodiments, the body portion 281 has a body portion connecting groove 2811, and the foot portion 282 has a foot portion protrusion 2821. The foot portion 282 is connected to the body portion 281 by the engagement of the body portion connecting groove 2811 and the foot portion protrusion 2821. In some embodiments, the foot portion protrusion 2821 is cylindrical with a diameter of a second dimension, and the inner diameter of the body portion connecting groove 2811 is also a second dimension.

[0127] In some embodiments, the foot protrusion 2821 is a cylinder with a diameter of 4.8 mm to 4.9 mm, and the inner diameter of the body connecting groove 2811 is 4.8 mm to 4.9 mm.

[0128] In some embodiments, the body connecting groove 2811 is the same size as the first connecting groove 220, so that the seagull-shaped block structure 1000 can be directly connected to the first block connecting part 2100 of other external blocks 2000 through the body connecting groove 2811. If the other blocks 2000 are represented as a horizontal plane, it can be shown that the seagull is swimming on it without showing the feet 282.

[0129] In addition, the first connecting part 210 may be provided on the body part 281.

[0130] In some embodiments, such as Figures 5a-5e As shown, the main body 200 has a plurality of first connecting grooves 220, which cooperate with the plurality of first building block connecting parts 2100 of the building block 2000 to allow the main body 200 to be installed on other building blocks 2000.

[0131] In some embodiments, the shape of the block structure 1000 is animal-shaped. It should be noted that the design of the body part 281 varies depending on the different block structures 1000. In some embodiments, the shape of the body part 281 can be that of an owl, a fish, a bear, a dog, a pig, a pigeon, a squirrel, a cat, a chicken, etc., and the shape of the feet 282 can be that of an owl, a bear, a dog, a pig, a pigeon, a squirrel, a cat, a chicken, etc.

[0132] When multiple building blocks are assembled, if the building block structure 1000 is too wide, the bottom of the building block structure 1000 may interfere with or obstruct the first connecting part 2100 of the adjacent building block (e.g., the left or right building block), affecting subsequent assembly. Therefore, in some embodiments, the building block structure 1000 can be detachably connected to other building block structures 1000 by engaging with the first connecting part 2100 of the other building block structures 1000. The width of the building block structure 1000 is greater than the fourth dimension, and the portion of the building block structure 1000 whose distance from the central axis O exceeds the seventh dimension is the excess region 290, wherein the central axis O is perpendicular to the width direction of the building block structure 1000. The seventh dimension can be 4.0 mm.

[0133] Specifically, the width of the building block structure 1000 is greater than the fourth dimension; in some embodiments, this means that the width of the building block structure 1000 is greater than 7.8 mm.

[0134] In the building block structure 1000, the portion of the distance from the central axis O of the building block structure 1000 that exceeds the seventh dimension is defined as the excess region 290. This can be understood as the portion of the left or right edge of the building block structure 1000 that extends beyond the central axis O exceeding the seventh dimension, and the portion extending beyond the left or right edge being the excess region 290. In some embodiments, the diameter of the first connecting portion 2100 of a conventional building block is generally 4.8mm or 4.9mm, and the height is generally 1.7mm-1.9mm. The distance between the centers of two adjacent first connecting portions 2100 is 8.0mm, and the seventh dimension is the midpoint dimension of the two adjacent first connecting portions 2100, which is 4.0mm.

[0135] In some embodiments, when the building block structure 1000 is installed on a first building block connection portion 2100 of other building blocks 2000, the bottom surface of the area 290 is set higher than the top surface of the first building block connection portion 2100 adjacent to the first building block connection portion 2100 where the main body 200 is installed, such as... Figure 8k As shown, this makes the area 290 higher than the first block connection 2100, thereby avoiding interference and obstruction between the block structure 1000 and the adjacent first block connection 2100, so that the block structure 1000 cannot be assembled smoothly.

[0136] In some embodiments, such as Figure 6e As shown, the block structure 1000 is configured such that the bottom surface of the area 290 is flush with the top surface of the first block connection portion 2100 of the adjacent block. Since the bottom surface of the area 290 is flush with the top surface of the first block connection portion 2100, interference and obstruction between the block structure 1000 and the adjacent first block connection portion 2100 can be avoided.

[0137] In some embodiments, a clearance groove 291 is provided beyond the area 290, so that the clearance groove 291 can accommodate the adjacent first block connection portion 2100, so as to avoid interference and obstruction with the adjacent first block connection portion 2100.

[0138] In some embodiments, the width 292 of the extended region 290 is less than the eighth dimension (in some embodiments, the eighth dimension is 1.6 mm), that is, the width 292 of the extended region 290 is less than 1.6 mm. Specifically, the distance between the centers of the first block connection portion 2100 of two adjacent blocks can be 8.0 mm, and the diameter of the first block connection portion 2100 is 4.8 mm or 4.9 mm. When the width of the extended region 290 is less than (8.0-4.8) / 2=1.6 mm, normally the extended region 290 will not interfere with other blocks or hinder the entire assembly.

[0139] It should be noted that in some embodiments, the building block structure 1000 can be engaged with the first building block connecting part 2100 of other building block structures 1000 through the first connecting groove 220 to be detachably connected to other building block structures 1000.

[0140] In some embodiments, such as Figure 9a As shown, the head 100 is mounted on the side of the main body 200, and a first connecting groove 220 is formed at the bottom of the head 100. The width 221 of the first connecting groove is a second dimension. Specifically, for example, in a fish-shaped building block structure 1000, the head 100 is located on the front side of its main body 200. In this case, the bottom of its head 100 can have a first connecting groove 220 formed to connect with the first building block connecting part 2100 of other building blocks 2000.

[0141] In some embodiments, the first connecting groove 220 is formed with a fourth connecting hole 222, the size of which is a first dimension. Specifically, the bottom surface of the first connecting groove 220 is recessed inward to form the fourth connecting hole 222, so that the head 100 can connect different building block 2000 parts through the first connecting groove 220 or through the fourth connecting hole 222, thereby achieving the purpose of connecting building block 2000 parts of different shapes.

[0142] In some embodiments, the head 100 has a first opening 140, and a first connecting hole 110 communicates with the first opening 140. Specifically, the first opening 140 formed in the head 100 can serve as the mouth of an animal. Therefore, it is possible to connect to other building blocks 2000 with inserts through the first opening 140 at the mouth of the animal. In some embodiments, the insert can be the first connecting portion 210 of the building block 2000, etc.

[0143] like Figures 9a-9e As shown, the building block structure 1000 can simultaneously form a second connecting hole 222 in the first connecting groove 220 and a first opening 140 in the head 100. In some embodiments, the first opening 140 connects to the first connecting groove 220, which also facilitates the production of the head 100 and increases the possibility of connecting the head 100 with other building blocks 2000.

[0144] In some embodiments, the second connecting hole 222 communicates with the first connecting hole 110. The second connecting hole 222 communicates with the first connecting hole 110 to facilitate the injection molding of the head 100, and also to facilitate the insertion of flexible wires through the communicating first connecting hole 110 and second connecting hole 222.

[0145] In some embodiments, the main body 200 is vertically symmetrical about the axis M of the first connecting part and / or the modular structure 1000 is horizontally symmetrical about the axis M of the first connecting part. When the main body 200 is vertically symmetrical about the axis M of the first connecting part, the main body 200, which has a curved or tilted posture, can maintain consistency after rotating relative to the head 100. For example, if the main body 200 is the body of a fish, and the main body 200 is vertically symmetrical about the axis M of the first connecting part, that is, the pelvic fins and dorsal fins of the fish body are vertically symmetrical about the axis, and the left and right pectoral fins are also vertically symmetrical about the axis, then if the fish body is rotated relative to the fish head, the original pelvic fins become the new dorsal fins, and the original dorsal fins become the new pelvic fins, and the left and right pectoral fins are interchanged, so that the fish body after rotating 180 degrees also maintains the positional consistency with the fish head. On the one hand, it is convenient for users to assemble the fish head and the fish body. On the other hand, if the fish body is curved, the left-curved fish tail can be rotated into a right-curved fish tail, and the normal shape of the fish is maintained after the dorsal fins and pelvic fins are interchanged and the left and right pectoral fins are interchanged.

[0146] Alternatively, if the main body 200 is symmetrical about the axis M of the first connecting part, the production and design difficulties can be reduced, and the aesthetic appeal of the symmetry can also be improved.

[0147] Alternatively, the main body 200 can be both vertically and horizontally symmetrical based on the axis M of the first connecting part, so that the main body 200 can have the advantages of both vertical and horizontal symmetry.

[0148] In some embodiments, such as Figure 7a As shown, the main body 200 has at least one set of claw assemblies 283. Each claw assembly 283 includes two claw portions 2831, and a columnar object with a cross-sectional diameter of a first dimension can be accommodated between the two claw portions 2831 of the same claw assembly 283. Specifically, the two claw portions 2831 can cooperate to form a slot 284 to hold an object located between the two claw portions 2831. In some embodiments, the first dimension is 3.2 mm, that is, the width of the slot 284 between the two claw portions 2831 is 3.2 mm. Through the design of the two claw portions 2831, structures such as the first connecting portion 210 (specifically, a stick) can be located between the two claw portions 2831 to reproduce the expression form of the building block structure 1000 grasping the columnar object through the claw assembly 283, and can also express the building block structure 1000 achieving high-difficulty postures such as climbing by grasping the columnar object, thereby improving the expressive diversity of the building block structure 1000.

[0149] In some embodiments, such as Figure 8h As shown, the main body 200 has a third connecting hole 215, and the first connecting part 210 is installed in the third connecting hole 215. Specifically, since the main body 200 has a third connecting hole 215 in some embodiments, the user can insert the first connecting part 210 into the third connecting hole 215 or remove the first connecting part 210 from the third connecting hole 215 at any time as needed.

[0150] like Figure 8f As shown, the head 100 has a fourth connecting groove 150 formed at the first connecting hole 110. The fourth connecting groove 150 is used to accommodate the second-sized column, so that the head 100 can be inserted into the second-sized column alone. In existing building block toys, the second-sized column can be a column decoration or the neck of a humanoid building block, so that the animal's head can be installed on the humanoid building block, forming new building play and creative expression. It is also possible to use a head 100 (e.g., an animal shape) to be applied to both the animal body and the humanoid building block body at the same time.

[0151] Alternatively, both ends of the first connecting part 210 can be inserted into the first connecting hole 110 and the third connecting hole 215 respectively, so as to disassemble the first connecting part 210 or replace it with a 210 of different lengths. In addition, in some embodiments, the user can connect the head 100 and the body 200 by inserting the first connecting part 210 into the first connecting hole 110 and the third connecting hole 215 respectively.

[0152] In some embodiments, such as Figure 8j As shown, the modular structure 1000 also includes a third connecting portion 300, which extends outward to form a boss 310. The main body 200 has a third connecting groove 216 formed at the third connecting hole 215. The boss 310 of the third connecting portion 300 abuts against the third connecting groove 216 to limit the position of the third connecting portion 300 entering the main body 200. The end of the third connecting portion 300 away from the boss 310 is inserted into the first connecting hole 110. Specifically, the third connecting portion 300 can replace the first connecting portion 210, that is, the head 100 and the main body 200 are connected by the third connecting portion 300. Specifically, the third connecting portion 300 has a boss 310, and the main body 200 has a third connecting groove 216, so the boss 310 of the third connecting portion 300 and the third connecting groove 216 cooperate to limit the position of the third connecting portion 300 entering the main body 200. Furthermore, the end of the third connecting portion 300 away from the boss 310 can be inserted into the head 100, so the body and the head 100 can be connected through the third connecting portion 300. The third connecting groove 216 can be a recessed design. In some embodiments, the third connecting portion 300 includes a first end portion 320, a boss 310, and a second end portion 330 connected in sequence. The first end portion 320 is a cylindrical structure with an outer diameter of a first dimension. The second end portion 330 is a cylindrical structure with an outer diameter of the first dimension. The boss 310 is a cylindrical structure with an outer diameter of the second dimension.

[0153] In some embodiments, the width 2161 of the third connecting slot is a second dimension, namely 4.8 mm. Therefore, the third connecting slot 216 can be used to connect with the first block connecting part 2100 of other blocks 2000, enabling a wider variety of assembly methods.

[0154] In some embodiments, the head 100 has a through hole 160 extending from the top of the head 100 to the first connecting hole 110. The through hole 160 allows for pressure balance on both sides of the first connecting hole 110 when it is connected to the first connecting portion 210 or the second connecting portion 251. It also allows breathing through the through hole 160 in case the head 100 is accidentally swallowed (when no other structure is inserted into the first connecting hole 110), preventing suffocation. The through hole 160 has a ninth dimension. In some embodiments, the ninth dimension is 2.6 mm. Furthermore, other building blocks 2000 can be inserted into the through hole 160 as decorations for the head 100.

[0155] In some embodiments, the building block structure 1000 includes a first attachment 400, and a snap-fit ​​groove is formed at the bottom of the main body 200. The main body 200 and the first attachment 400 are detachably connected through the engagement between the first attachment 400 and the snap-fit ​​groove. In some embodiments, the shape of the main body can be that of a shrimp body or a crab body, and the snap-fit ​​groove is formed at its bottom. The shape of the first attachment is roughly that of two pincers. Therefore, after connecting the main body and the first attachment, a building block structure 1000 resembling a lobster or crab shape can be formed, so as to share the first attachment, reduce the repeated production of the first attachment, improve the diversity of expression of the first attachment, and increase playability.

[0156] Furthermore, the first accessory 400 may also be provided with a receiving groove, the size of which (can be width or diameter) is a first dimension, so that the first accessory 400 can also snap onto a columnar object of the first dimension. It should be noted that, in some embodiments, the slot 284 between the two claws 2831 of the building block structure 1000 can also serve as a snap-fit ​​slot for connection with the first accessory 400.

[0157] Specifically, a fourth connecting portion 218 is formed on the side of the main body 200, and the outer diameter of the fourth connecting portion 218 is a first dimension. This allows an external building block equipped with a C-shaped latch (such as a human-shaped building block with a C-shaped hand) to snap into the fourth connecting portion 218, thereby fixing the main body 200 to the external building block 2000, and also improving the diversity of installation scenarios and expressive possibilities of the building block structure 1000 of this disclosure. Specifically, as Figure 8d As shown, the hand portion of the bear-shaped block structure 1000 can serve as a fourth connecting portion 218, which is snapped together with the external blocks. Furthermore, in some embodiments, the fourth connecting portion 218 can extend beyond the area 290, either partially or entirely.

[0158] It should be understood that the various processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this utility model can be executed in parallel, sequentially, or in different orders, as long as it is feasible. The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this disclosure without departing from the scope of the technical solution of this disclosure shall still fall within the scope of the technical solution of this disclosure.
