DETAILED DESCRIPTION

[0058] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0059] In the description of the present application, it should be noted that the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or components referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0060] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0061] As Figures 1 to 11As shown, the firestone toy car provided by the embodiments of the present application comprises a vehicle body 1, a wheel assembly 2 and a mounting seat 3. The vehicle body 1 is provided with a driving mechanism 4. The wheel assembly 2 comprises a wheel 21, an elastic member 22 and a firestone 23, wherein the wheel 21 is connected to the driving mechanism 4, and the elastic member 22 is arranged on the wheel 21. The mounting seat 3 is fixed to the vehicle body 1, and a friction member 5 is arranged on the mounting seat 3. The friction member 5 is located on the side of the wheel 21 close to the vehicle body 1, and the firestone 23 is located between the elastic member 22 and the friction member 5. The elastic member 22 elastically abuts against the firestone 23, so that the firestone 23 elastically abuts against the friction member 5. The driving mechanism 4 drives the wheel 21 to rotate, so that the elastic member 22 and the firestone 23 rotate relative to the friction member 5.

[0062] The firestone toy car disclosed by the present application has the basic moving function and innovatively introduces the design of generating sparks by friction of firestone. When the driving mechanism 4 drives the wheel 21 to rotate, the elastic member 22 and the firestone 23 rotate relative to the friction member 5. Under the action of the elastic member 22, the firestone 23 continuously rubs against the friction member 5, so as to generate sparks, which brings new visual experience to children and greatly enhances the interestingness and playability of the toy car, so as to better meet the exploration desire and entertainment demand of children for toys and has unique application value and market prospect in the technical field of toy cars.

[0063] Moreover, the sparks are generated by the interaction between the firestone and the friction member 5 when the wheel 21 rotates, which not only realizes the dynamic light-emitting effect, but also reduces the manufacturing cost without complex circuit design. Meanwhile, the light effect is more natural and changeable, which greatly improves the interestingness and attractiveness of the toy car.

[0064] In some possible embodiments, the wheel assembly 2 comprises a sleeve 24 arranged on the wheel 21, and the elastic member 22 is located in the sleeve 24. Such a design can effectively protect the elastic member 22 from being interfered or damaged by foreign matters during the rotation of the wheel 21, so as to ensure that the elastic member 22 can stably play the elastic role and continuously push the firestone 23 to tightly contact the friction member 5, thereby ensuring the stability and persistence of spark generation. Meanwhile, the sleeve 24 can also guide the elastic member 22 to be more smooth during compression and stretching, so as to further improve the effect of generating sparks by the toy car.

[0065] In some possible embodiments, the wheel 21 comprises a wheel body 211 connected to the driving mechanism 4, and a cover 212 detachably connected to a side of the wheel body 211 away from the mounting base 3, the cover 212 enclosing an outer port of the through groove 21131. The sleeve 24 and the spring are arranged in the through groove 21131, so that the wheel 21 can stably drive the flint 23 to rotate, and the generated sparks are better. The design that the cover 212 encloses the outer port of the through groove 21131 can prevent dust and sundries from entering the through groove 21131, protect the internal components from pollution and damage, and prolong the service life of the toy car. Moreover, this structure makes the installation and disassembly of the internal components of the wheel 21 more convenient. When the elastic member 22, the flint 23 or the sleeve 24 needs to be maintained or replaced, the cover 212 is only needed to be detached, and then the components in the through groove 21131 can be directly operated, so that the maintenance and repair efficiency is greatly improved.

[0066] In some possible embodiments, the wheel body 211 comprises a hub 2111, a rim 2112 located at a circumferential side of the hub 2111, and spokes 2113 connected to the hub 2111 and arranged in sequence and spaced apart along a circumferential direction of the hub 2111, and gaps are arranged between adjacent two spokes 2113, and the through groove 21131 is arranged on at least part of the spokes 2113. The spaced arrangement of the spokes 2113 not only reduces the overall weight of the wheel 21, but also makes the toy car more flexible and light during driving. Moreover, the gaps between the spokes 2113 provide a space for the sparks to be seen or ejected, so that the toy car has higher ornamental and interesting properties.

[0067] In some possible embodiments, a connecting hole is arranged in a middle portion of the cover 212, one end of a connecting member is connected to the wheel body 211 and / or the driving mechanism 4 through the connecting hole, and the other end of the connecting member is limited in the cover 212. The connecting member connects the cover 212 with the wheel body 211 or the driving mechanism 4, so that the cover 212 is more firmly and reliably installed, and the cover 212 will not be loosened or detached due to vibration during driving of the toy car, so that the through groove 21131 is always in a closed state, and the safety of the internal components is ensured. Moreover, this connection method is simple and easy to implement, and is convenient for production and assembly, so that the production efficiency of the toy car is improved.

[0068] In some possible embodiments, the cover 212 has a middle body 2121, an outer ring 2122, and a plurality of connecting strips 2123, each of the connecting strips 2123 is sequentially and spacedly arranged along the circumference of the middle body 2121, and the connecting strip 2123 is connected to the middle body 2121, the two ends of the connecting strip 2123 are connected to the middle body 2121 and the outer ring 2122 respectively, the middle body 2121 is provided with the connecting hole, each of the connecting strips 2123 covers a corresponding spoke 2113 respectively, and a hollow part is formed between adjacent connecting strips 2123. The connecting strip 2123 covers the spoke 2113, which can shield the through groove 21131 and prevent the elastic member 22 and the flint 23 inside from falling off. The hollow part between the connecting strips 2123 is beneficial to provide a clearance space, so that the sparks wiped out can be seen or ejected from the gap, and the watchability and interest are higher.

[0069] In some possible embodiments, the through groove 21131 includes a main groove 211311 and an end groove 211312 located at one end of the main groove 211311 close to the cover 212, the main groove 211311 and the end groove 211312 are connected in communication, the connecting strip 2123 is provided with a boss 21231, the boss 21231 is embedded in the end groove 211312, and one end of the elastic member and the sleeve 24 is limited. The design that the boss 21231 is embedded in the end groove 211312 can accurately limit one end of the elastic member and the sleeve 24, prevent them from shifting or shaking during the rotation of the wheel 21, ensure that the elastic member 22 always stably pushes the flint 23 to tightly contact the friction member 5, and thus guarantee the stability and continuity of spark generation. This limiting mode is simple in structure but very effective, does not need complex mechanical structures or additional fixing devices, reduces the production cost, and improves the reliability and durability of the toy car.

[0070] In some possible embodiments, the spoke is provided with a limiting groove 21132, the limiting groove 21132 is a strip-shaped groove, one end of the limiting groove 21132 is connected in communication with the end groove 211312, the elastic member is a spring, one end of the spring is provided with a torsion arm 221, and the torsion arm 221 is limited in the limiting groove 21132. The cooperation of the limiting groove 21132 and the torsion arm 221 provides more accurate positioning for the spring, so that the spring can move along a predetermined track during compression and stretching, and the problems of performance decline or interference with surrounding components caused by deviation of the spring are avoided. At the same time, this limiting structure can also effectively prevent the spring from being twisted and deformed during the rotation of the wheel 21, and ensure that the spring can always stably play an elastic role, and provide reliable elastic support for the continuous friction between the flint 23 and the friction member 5.

[0071] In some possible embodiments, the mounting base 3 comprises a first seat body 31 fixed to the vehicle body 1 and a second seat body 32 connected to the first seat body 31, and the first seat body 31 and the second seat body 32 clamp the friction member 5. This split design makes the installation and disassembly of the friction member 5 more convenient and fast. When the friction member 5 needs to be replaced due to long-term use and wear, the second seat body 32 can be separated from the first seat body 31, and the old friction member 5 can be easily taken out and a new friction member 5 can be installed without complex disassembly operation of the entire mounting base 3, thereby greatly improving the efficiency of maintenance and repair. At the same time, through the clamping and fixing of the first seat body 31 and the second seat body 32, the friction member 5 can be firmly installed on the mounting base 3 and will not be loose or displaced during the rotation of the wheel 21, thereby ensuring that the friction effect between the flint 23 and the friction member 5 is always stable and reliable.

[0072] In some possible embodiments, the friction member 5 is a ring-shaped sandpaper, the first seat body 31 comprises a circular ring table 311 having a central hole 312, the ring-shaped sandpaper is attached to the circular ring table 311, the second seat body 32 comprises an outer ring body 321 and an extension ring 322 arranged on the inner side edge of the outer ring body 321, the outer diameter of the outer ring body 321 is smaller than the outer diameter of the ring-shaped sandpaper, the outer ring body 321 and the circular ring table 311 clamp the inner side edge of the ring-shaped sandpaper, the extension ring 322 is inserted and fixed on the inner wall of the central hole 312 of the circular ring table 311, and the driving mechanism 4 has a driving shaft assembly 42 connected to the wheel 21 through the central hole 312 of the circular ring table 311.

[0073] This design makes the overall structure more compact and the connection between the components more stable. The ring-shaped sandpaper as the friction member 5 has moderate surface roughness and can produce stable and obvious spark effect when rubbing with the flint 23. Moreover, the ring-shaped sandpaper has low cost and is easy to replace. When the surface of the sandpaper becomes smooth due to long-term friction and affects the spark generation effect, the old sandpaper can be easily removed and replaced with a new ring-shaped sandpaper to restore the function of the toy car to generate sparks.

[0074] The circular ring table 311 of the first seat body 31 not only provides a basis for the placement of the ring-shaped sandpaper, but also provides a passage for the driving shaft assembly 42 to pass through, so that the driving mechanism 4 can smoothly transmit power to the wheel 21. The design of the circular ring table 311 is simple and practical, which ensures the structural strength without causing excessive impact on the overall weight of the toy car.

[0075] The cooperation of the outer ring body 321 of the second seat body 32 and the extension ring 322 further enhances the fixing effect of the annular sandpaper. The outer diameter of the outer ring body 321 is smaller than the outer diameter of the annular sandpaper, and such a size design enables the outer ring body 321 to be accurately clamped on the inner side edge of the annular sandpaper without causing obstruction to the outer side of the sandpaper, thereby ensuring sufficient contact between the sandpaper and the flint 23. The extension ring 322 is inserted and fixed on the inner wall of the central hole 312 of the circular ring table 311, and such an insertion connection is firm and relatively simple to install and disassemble, and can be quickly operated when maintenance or replacement of parts is required.

[0076] The motor 41 and the drive shaft assembly 42 of the driving mechanism 4 are the core parts of power transmission of the toy car. The motor 41 provides power, and the power is transmitted to the wheels 21 through the drive shaft assembly 42, so that the wheels 21 can rotate. The drive shaft assembly 42 is connected to the wheels 21 through the central hole 312 of the circular ring table 311, and such a layout reasonably utilizes the space, so that the power transmission is more direct and efficient.

[0077] The above only describes the preferred embodiments of the present application, and does not limit the present application in any form. Although the preferred embodiments of the present application have been disclosed as above, the present application is not limited thereto. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiments, which do not depart from the technical solution of the present application, are still within the scope of the present application.
