[0026] refer to Figures 1 to 14 , a building block, characterized by comprising:

[0027] The building block body 1 is formed by a plurality of side walls 2 connected to each other. The plurality of side walls 2 include a first surrounding wall group 21, an upper side wall 22, and a lower side wall 23 connected in sequence. The upper side of the first surrounding wall group 21 is connected to the upper side wall 22, and the lower side of the first surrounding wall group 21 is connected to the lower side wall 23. The first surrounding wall group 21, the upper side wall 22, and the lower side wall 23 together surround and form a first cavity 10.

[0028] The mounting housing 3 is connected to the upper side wall 22 and is located within the first chamber 10. The mounting housing 3 is equipped with a light-emitting component 4. Through this structure, the user can turn on the light-emitting component 4 inside the building blocks while stacking them. Compared with traditional building blocks, the light-emitting building blocks greatly increase the aesthetics and fun of the building blocks. The light-emitting building blocks can better stimulate the user's creativity, increase the user's interest in building block toys, and enhance the purchasing appeal of building block products.

[0029] In this embodiment, the light emitting assembly 4 includes a battery assembly 41 and a light emitting element 42 electrically connected to the battery assembly 41 . The battery assembly 41 is used to supply power to the light emitting element 42 .

[0030] In this embodiment, a switch assembly 5 is further included. The switch assembly 5 is provided on the building block body 1 and is electrically connected to the light emitting assembly 4 . The switch assembly 5 is used to control the light emitting element 42 to be turned on or off.

[0031] In this embodiment, the mounting housing 3 includes a mounting chamber 31 and a positioning retainer 32 disposed on the outer wall of the mounting housing 3. The battery assembly 41 is located within the mounting chamber 31, and the light-emitting element 42 is secured to the positioning retainer 32 and electrically connected to the battery assembly 41. This structure allows the battery assembly 41 to be placed within the mounting chamber 31 and the light-emitting element 42 to be attached to the outside of the mounting housing 3. This simple and rational design ensures that the light emitted by the light-emitting element 42 is transmitted through the outer wall of the building block to the greatest extent possible.

[0032] As attached Figure 14 In another embodiment, the battery assembly 41 and the light emitting element 42 can both be disposed in the mounting chamber 31. The switch assembly 5 is an elastic wall of the upper side wall 22 of the building block. The elastic wall is disposed above the LED light switch. By pressing the elastic wall, the switch is pressed, thereby controlling the on or off of the LED light.

[0033] In this embodiment, the installation chamber 31 is provided with a first stop block group 311 and a second stop block group 312, and the first stop block group 311 and the second stop block group 312 are respectively arranged near the opposite ends of the installation chamber 31, and the first stop block group 311 and the inner wall of the installation chamber 31 are surrounded by a first card groove 3111, and the second stop block group 312 and the inner wall of the installation chamber 31 are surrounded by a second card groove 3121. The first stop block group 311, the second stop block group 312 and the inner wall of the installation chamber 31 are jointly surrounded by a third card groove 313, and the first card groove 3111, the third card groove 313 and the second card groove 3121 are connected in sequence; the battery assembly 41 includes a positive conductive sheet 411, a negative conductive sheet 412 and a battery 413, the positive conductive sheet 411 is arranged in the first card groove 3111, the negative conductive sheet 412 is arranged in the second card groove 3121, and the battery 413 is arranged in the third card groove 313. With the above structure, when the battery 413 is placed in the third slot 313 , both ends of the battery 413 can directly contact and communicate with the positive conductive sheet 411 and the negative conductive sheet 412 respectively, ensuring that the battery 413 can effectively power the light-emitting element 42 subsequently.

[0034] Furthermore, the bottom wall of the mounting shell 3 has a first through hole 314 and a second through hole 315, the first through hole 314 is located in the first card slot 3111, and the second through hole 315 is located in the second card slot 3121, the positive conductive sheet 411 includes a first clamping end 4111 and a first connection end 4112, and the negative conductive sheet 412 includes a second clamping end 4121 and a second connection end 4122. When the first clamping end 4111 is clamped in the first card slot 3111, the first connection end 4112 can pass through the first through hole 314 and extend out of the outer wall of the mounting shell 3. When the second clamping end 4121 is clamped in the second card slot 3121, the second connection end 4122 can pass through the second through hole 315 and extend out of the outer wall of the mounting shell 3.

[0035] Furthermore, the positioning card holder 32 is connected to the bottom wall of the mounting housing 3. The positioning card holder 32 has a positioning groove 321 and a first connection hole 322 and a second connection hole 323 connected to the positioning groove 321. The light-emitting element 42 includes a lamp bead 421 and a positive pin 422 and a negative pin 423 electrically connected to the lamp bead 421. The lamp bead 421 is located in the positioning groove 321. The positive pin 422 passes through the first connection hole 322 to be electrically connected to the positive conductive sheet 411, and the negative pin 423 passes through the second connection hole 323 to be electrically connected to the switch assembly 5. The above structure is cleverly designed. When the positive pin 422 of the lamp bead 421 passes through the first connection hole 322, the lamp bead 421 can be clamped to the positioning card holder 32, and the electrical connection between the lamp bead 421 and the battery 413 is ensured, further ensuring that the lamp bead 421 emits light.

[0036] In this embodiment, the upper side wall 22 has a switch through hole 221, the first chamber 10 is provided with a limiting structure 6 connected to the first surrounding wall group 21, and the switch assembly 5 includes, from top to bottom, a push block 51, a control unit block 52, and a first conductive pin 53, a second conductive pin 54, and a third conductive pin 55. The first conductive pin 53 is electrically connected to the negative conductive sheet 412, and the second conductive pin 54 is electrically connected to the negative pin 423. The control unit block 52 is located above the limiting structure 6 to allow the push block 51 to pass through the switch through hole 221. Through the above structure, due to the presence of the limiting structure 6, the push block 51 in the switch assembly 5 can be limited to the switch through hole 221 and prevented from falling, so that the user can push the push block 51 to control the light-emitting element 42.

[0037] In this embodiment, the limiting structure 6 includes a first limiting vertical plate 61 and a second limiting vertical plate 62 connected to the first surrounding wall group 21. The first limiting vertical plate 61 and the second limiting vertical plate 62 are used to support the control unit block 52 so that the push block 51 can pass through the switch through hole 221. The above structure is simple and ingenious. The upper sides of the first limiting vertical plate 61 and the second limiting vertical plate 62 stop the control unit block 52 of the switch assembly 5 in a specific position, allowing the push block 51 to pass through the switch through hole 221, thereby facilitating the user to push the push block 51 to realize the switch assembly 5 to control the light-emitting lamp 421.

[0038] like Figure 10 In another embodiment, the limiting structure 6 includes a first limiting vertical plate 61, a second limiting vertical plate 62, and a limiting horizontal plate 63 connected to the first surrounding wall group 21. The first limiting vertical plate 61 and the second limiting vertical plate 62 are tightly positioned below the limiting horizontal plate 63. The limiting horizontal plate 63 is used to support the control unit block 52 so that the push block 51 can pass through the switch through-hole 221. With the above structure, the design of the limiting horizontal plate 63 plus two limiting vertical plates is more secure, and the control unit block 52 can be more firmly pressed against the limiting horizontal plate 63, ensuring that the push block 51 is not easily misaligned or dropped when the user pushes it.

[0039] In this embodiment, the push block 51 has an open state and a closed state. When the push block 51 is pushed to the open state, the first conductive pin 53 connects to the negative conductive sheet 412, and the lamp bead 421 emits light. When the push block 51 is pushed to the closed state, the first conductive pin 53 is disconnected from the negative conductive sheet 412, and the lamp bead 421 does not emit light. With this structure, the user can push the push block 51 until the first conductive pin 53 connects to the negative conductive sheet 412 of the battery assembly 41. At this time, the battery assembly 41 and the switch assembly 5 form a complete closed circuit, and the light-emitting lamp bead 421 can emit light. The design is simple and ingenious.

[0040] In this embodiment, the upper side wall 22 has an opening 222 that communicates with the mounting chamber 31. The opening 222 is connected to a matching cover 223. The design of the cover 223 facilitates user replacement of the battery 413 and the lamp 421, ensuring that the battery 413 can be replaced promptly if it runs out of power or the lamp 421 is damaged.

[0041] In this embodiment, the lamp bead 421 may be an LED lamp bead 421. The LED lamp bead 421 is durable and affordable, which can save manufacturing costs.

[0042] In this embodiment, the upper sidewall 22 is further provided with a hand-push groove 224, within which the switch through-hole 221 is located. The height of the push block 51 is lower than that of the upper sidewall 22. This structure ensures that the area of ​​the hand-push groove 224 is larger than that of the switch through-hole 221, making it easier for the user to push the push block 51 with their fingers. Furthermore, the height of the push block 51 is lower than that of the upper sidewall 22, preventing the protrusion of the push block 51 from causing unevenness when the building blocks are stacked, thereby hindering the construction of the building block shapes.

[0043] In this embodiment, an intersection corner 7 is formed at the connection between adjacent side walls 2, and a compartment 8 is provided at the intersection corner 7. A magnet 9 is provided in the compartment 8; the magnet 9 can rotate in the compartment 8, and the magnet 9 has an N pole and an S pole. Through the above structure, the magnetic building blocks can be attracted to each other through the first magnet 9 provided in the first compartment 8 at the intersection corner 7, so that the magnetic building blocks can be connected to each other at the intersection corner 7, thereby realizing a staggered connection between the magnetic building blocks, thereby realizing the design and construction of staggered shapes. Compared with the magnetic building blocks in the prior art that can only be stacked on the same axis, the construction method and play method of the magnetic building blocks are greatly enriched, which can help children build more shapes, and can be combined with the surface pattern of the magnetic building blocks to build a variety of pattern combinations, greatly increasing children's interest in building shapes and helping to develop children's imagination. And because the first magnet 9 can rotate in the first compartment 8, the first magnet 9 has an N pole and an S pole, so when the magnetic blocks are stacked on each other at the intersection corner 7, the first magnet 9 of the magnetic block can be easily rotated to guide the N pole of the magnetic block to be tightly adsorbed with the S pole of another identical magnetic block, or guide the S pole of the magnetic block to be tightly adsorbed with the N pole of another identical magnetic block, so as to achieve a stable connection between the magnetic blocks and a staggered connection between the magnetic blocks, so as to realize the design and construction of staggered shapes.
