Description

Technical Field

[0001] This utility model relates to the field of electronic assembly toy technology, and more particularly to a universal fixing structure for assembly circuit toys and a toy car. Background Technology

[0002] Building block toys are a type of toy that combines building block structures with electronic circuit structures. Players can use their creativity to assemble various circuit structures to achieve corresponding electronic functions. A common example is the electronic building blocks provided in publication number CN2855493Y. By assembling various electronic functional blocks and connecting wires on an insulating base plate according to circuit principles, the function of the circuit can be realized. There is also a type of building block toy on the market that allows functional blocks to be assembled on both sides of the base plate to achieve richer electronic functions. For example, a remote-controlled building block toy car provided in publication number CN215538401U can automatically connect a building block battery box and a building block control board to one side of the frame surface, and a driven moving component and a driving moving unit to the other side of the frame surface, thus driving the frame and forming a remote-controlled toy car. However, since conventional insulating base plates only have protrusions on one side of their surface, the remote control car needs to have connecting sleeves and other structures added to the frame plate to achieve double-sided assembly. In other words, the remote control car needs to have a new base plate structure designed, and conventional insulating base plates cannot be used as frame plates, resulting in poor uniformity of the toy structure and low versatility and applicability.

[0029] Please refer to Figures 1 to 7 This embodiment provides an assembly circuit toy car, including a base plate 100, a battery box 200, a controller 300, a drive assembly 400, and a follower assembly 500. The base plate 100 has multiple protrusions 110 and multiple through holes 120 arranged in rows and columns on one side surface. The battery box 200 and the controller 300 are detachably fixed to the protrusions 110. It is understood that the toy car also includes a universal fixing structure, through which the drive assembly 400 and the follower assembly 500 are detachably connected to the opposite side surface of the base plate 100. Therefore, this toy car does not require a redesigned base plate structure; a conventional base plate structure can be used to achieve the purpose of assembling various functional components on both sides of the base plate 100 through the universal fixing structure, significantly improving the toy's versatility and applicability.

[0030] In this embodiment, there are two drive components 400 and two follower components 500. Each drive component 400 includes a housing 410 detachably fixed to a first fixing member of the universal fixing structure, a motor installed inside the housing 410, and a drive wheel 420 driven by the motor. Each follower component 500 includes a bracket 510 detachably fixed to a second fixing member of the universal fixing structure, and a follower wheel 520 rotatably connected to the bracket 510. It is understood that the battery box 200, controller 300, drive components 400, and follower components 500 all adopt existing structures. The motor, battery box 200, and controller 300 are electrically connected to form a control loop, enabling the controller 300 to control the start and stop of the two motors upon receiving a control signal, thereby controlling the toy car to move, rotate, and spin. In other embodiments of this invention, the number of drive components 400 and follower components 500 can be adjusted according to the size of the base plate 100.

[0031] The universal fixing structure is used for detachably connecting the base plate 100 and functional components (such as the drive assembly 400, follower assembly 500, etc.), and includes a first fixing member 610 and a second fixing member 620. The first fixing member 610 is a hollow cylindrical structure, with a retaining plate 611 protruding outward from the outer wall at the open end. The first fixing member 610 can pass through the through hole 120 and be secured to the base plate 100 by the retaining plate 611. In this embodiment, a first connecting portion 10 is provided on the closed end of the first fixing member 610, through which the functional component can be detachably fixed to the first fixing member 610. The second fixing member 620 has a through groove 621 adapted to the first fixing member 610, and the through groove 621 and the first fixing member 610 are detachably fixedly connected by a connecting structure. When the through slot 621 is fixed to the first fixing member 610, the second fixing member 620 (the end wall of the through slot 621) cooperates with the clamping plate 611 to clamp the base plate 100, which can improve the stability of the first fixing member 610 in the through hole 120 and prevent the stability of the functional component on the base plate 100 from being affected by the shaking of the first fixing member 610. It can be understood that the connection structure includes a clamping block 631 and a clamping slot 632 separately disposed on the through slot 621 and the first fixing member 610. In this embodiment, the clamping slot 632 is provided on the side wall of the first fixing member 610, and the clamping block 631 is provided in the through slot 621. When the first fixing member 610 is inserted into the through slot 621, the clamping block 631 is snapped into the clamping slot 632, making the fixing operation convenient and quick. When it is necessary to disassemble the universal fixing structure from the base plate 100, the locking block 631 can be pushed apart from the buckle 632 by pushing the open end of the first fixing member 610. The disassembly operation is also convenient and quick. In other embodiments of this utility model, the first fixing member 610 may not have the first connecting part 10, and the first connecting part 10 may be provided only on the second fixing member 620. The positions of the locking block 631 and the buckle 632 can be interchanged, that is, the locking block 631 can be movably disposed on the outer wall of the first fixing member 610, and the buckle 632 can be correspondingly disposed on the groove wall of the through groove.

[0032] In this embodiment, the second fixing member 620 includes a first fixing block 620a and a second fixing block 620b. The first fixing block 620a does not have a first connecting portion 10, while the second fixing block 620b has a first connecting portion 10. Therefore, the first connecting portion 10 can be simultaneously provided on both the first fixing member 610 and the second fixing member 620. Specifically, the first connecting portion 10 on the first fixing member 610 can be exposed on the through groove 621, while the first connecting portion 10 on the second fixing member 620 is located outside the through groove 621. The first connecting portion 10 is detachably connected to the second connecting portion 20 on the functional component to fix functional components of different shapes and structures onto the base plate 100. Obviously, the first connecting portion 10 can be provided only on the first fixing member 610. In this embodiment, the first connecting portion 10 is a slot and the second connecting portion 20 is a post, and the post can be inserted and fixed into the slot. To increase the connection strength between the slot and the pin, the slot is provided with a locking step 11, and the end of the pin is provided with two elastically opening and closing legs 21. Each leg 21 is provided with a fixing block 22 that can be limited and abutted against the locking step 11. Inserting the pin into the slot so that the fixing block 22 engages with the locking step 11 achieves a relatively secure connection between the first connecting part 10 and the second connecting part 20. In other embodiments of this utility model, the second fixing member 620 may only include the first fixing block 620a or the second fixing block 620b, or the second fixing member 620 may also include a fixing block structure with other functional structures for fixing and connecting other functional components. The structures of the first connecting part 10 and the second connecting part 20 can be interchanged, i.e., the first connecting part 10 is set as a pin and the second connecting part 20 is set as a slot.

[0033] In this embodiment, the first fixing block 620a has an inner and outer double-cylinder structure. The inner cylinder of the first fixing block 620a has a through groove 621. Two locking blocks 631 are arranged opposite each other within the groove wall of the through groove 621. A movable hole 6211 is provided on the side wall of the locking blocks 631 within the through groove 621, allowing the locking blocks 631 to move elastically, facilitating the snap-fit ​​connection between the first fixing block 620a and the first fixing member 610. It can be understood that the outer cylinder of the first fixing block 620a serves to improve aesthetics and protect its inner cylinder from damage. In other embodiments of this utility model, the first fixing block 620a can be configured as a single-cylinder structure.

[0034] The second fixing block 620b includes a cylindrical body 6221 and a column 6222 arranged adjacent to each other. The cylindrical body 6221 has a through groove 621, and two locking blocks 631 are arranged opposite each other within the groove wall. The sidewall of the through groove 621 containing the locking blocks 631 is elastically movable to facilitate the snap-fit ​​connection between the second fixing block 620b and the first fixing member 610. The outer wall of the cylindrical body 6221 is fixedly connected to the column 6222 via an extension plate 6223. The column 6222 has a first connecting part 10. In this embodiment, the second fixing block 620b further includes an end panel 6224 integrally formed on the ends of the cylinder 6221 and the column 6222. A limiting block 6225 is provided on the opposite side of the end panel 6224 from the cylinder 6221 and the column 6222. The limiting block 6225 can be engaged and connected within the through hole 120 for limiting movement and preventing the second fixing block 620b from rotating freely. In other embodiments of this invention, the second fixing block 620 may not have the end panel 6224 and the limiting block 6225.

[0035] In summary, when the toy car provided in this embodiment needs to be fixedly connected to the base plate 100, the first fixing member 610 is first inserted into the through hole 120, so that the clamping plate 611 is clamped onto the base plate 100. Then, the first fixing block 620a is sleeved on the first fixing member 610 through the through groove 621. The through groove 621 and the first fixing member 610 are fixed through the connection structure to fix the first fixing block 620a to the outside of the first fixing member 610. At this time, the first fixing block 620a and the clamping plate 611 are sandwiched on both sides of the base plate 100, and the first connecting part 10 on the first fixing member 610 is exposed on the through groove 621. Finally, the second connecting part 20 on the box body 410 is inserted and fixed onto the first connecting part 10, so that the driving component 400 can be firmly connected to the base plate 100. When the toy car provided in this embodiment needs to be fixedly connected to the base plate 100, the first fixing member 610 is first inserted into the through hole 120, so that the clamping plate 611 is clamped onto the base plate 100. Then, the second fixing block 620b is sleeved on the first fixing member 610 through the through groove 621. The through groove 621 and the first fixing member 610 are fixed through the connection structure to fix the second fixing block 620b to the outside of the first fixing member 610. At this time, the second fixing block 620b and the clamping plate 611 are clamped on both sides of the base plate 100, and the limiting block 6225 is inserted into another through hole 120. Finally, the second connecting part 20 on the bracket 510 is inserted into the first connecting part 10 fixed on the column 6222, so that the follower component 500 can be firmly connected to the base plate 100.

[0036] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
