Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a high-capacity toy car. Background Technology

[0002] Current toy cars generally have small battery capacities, requiring frequent battery changes or recharging, which is inconvenient and cannot meet children's needs for extended playtime. Using large-capacity batteries would inevitably increase their size, causing them to be recessed significantly into the car's body. Since the car contains a driveshaft that simultaneously drives the front and rear wheels, the battery must be positioned to avoid this driveshaft, meaning it can only be placed on one side of the driveshaft in the width direction of the car. However, large-capacity batteries are heavy, and placing them on one side would make the car too heavy on one side, leading to instability and a tendency to tip over during play, affecting both the play experience and safety.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] See Figures 1 to 9As shown in the figure, this application embodiment provides a high-capacity toy car, including a car body 1, front wheels 2, rear wheels 3, a drive mechanism 4, a battery 5, a circuit board, and a counterweight 7. The front wheels 2 and the rear wheels 3 are respectively disposed at both ends of the car body 1 along its length. The drive mechanism 4 is disposed on the car body 1, and the drive mechanism 4 includes a first motor 41 and a drive shaft 42. The drive shaft 42 extends along the length of the car body 1, and its two ends are respectively connected to the front wheels 2 and the rear wheels 3 for transmission. The first motor 41 and the drive shaft 42 are connected for transmission. The battery 5 and the circuit board are disposed on the car body 1, and both the battery 5 and the drive mechanism 4 are electrically connected to the circuit board. The counterweight 7 is disposed on the car body 1, and the counterweight 7 and the battery 5 are arranged sequentially along the width of the car body 1, with the counterweight 7 and the battery 5 disposed on both sides of the drive shaft 42.

[0062] The high-capacity toy car disclosed in this application features a high-capacity battery 5 and a counterweight 7 installed on both sides of the drive shaft 42 in the width direction of the vehicle body 1. The high-capacity battery 5 provides continuous power to the toy car, while the counterweight 7 balances the weight of the vehicle body 1. The two work together to achieve a reasonable placement of the high-capacity battery and a balanced distribution of the weight of the vehicle body 1, effectively avoiding instability caused by excessive weight on one side. While solving the problem of insufficient power, the balance and maneuverability of the vehicle body 1 are also fully considered, providing children with a more stable and enjoyable play experience.

[0063] In some possible implementations, the vehicle body 1 has a chassis 11 and a shell 12. The chassis 11 has two accommodating cavities 111, located on either side of the drive belt shaft. The battery 5 and the counterweight 7 are housed within their respective accommodating cavities 111. The chassis 11 covers the bottom of the shell 12. This design not only provides the battery 5 and counterweight 7 with their own independent storage space, but also effectively protects them from damage or displacement due to collisions or other external forces during play, further ensuring the stability and safety of the toy car. Simultaneously, the arrangement of the two accommodating cavities 111 on either side of the drive belt shaft makes full use of the internal space of the vehicle body 1, resulting in a more compact and rational overall structure.

[0064] In some possible implementations, the high-capacity toy car includes a cover plate 13. Two openings are provided on the side of the chassis 11 facing away from the body shell 12, each opening connecting to a corresponding receiving cavity 111. The cover plate 13 is detachably connected to the chassis 11, and can simultaneously cover or open both openings. This design facilitates the installation, replacement, and maintenance of the battery 5 and counterweight 7 within the receiving cavity 111. When necessary, the cover plate 13 can be easily removed, making the operation simple and convenient.

[0065] In some possible implementations, the high-capacity toy car includes a baffle 14. The counterweight is embedded in a receiving cavity 111. The baffle 14 is detachably connected to the chassis 11, and the counterweight is confined between the baffle 14 and the chassis 11. With the cover plate 13 connected to the chassis 11, the cover plate 13 covers the baffle 14. The counterweight can be a metal block with high weight and density, resulting in high inertia. If there is room for movement, it will generate a large impact force. The baffle 14 further enhances the stability of the counterweight within the receiving cavity 111, preventing displacement due to shaking during the toy car's movement, thus ensuring the balance of the vehicle body 1 remains unaffected. Furthermore, during installation, the counterweight can be installed first, and then initially secured using the baffle 14 before installing the battery 5, making installation more convenient.

[0066] In some possible implementations, the bottom wall of the receiving cavity 111 is provided with a plurality of protrusions 1111, and the counterweight 7 is located between each of the protrusions 1111. One end of a screw passes through the counterweight 7 and is threadedly connected to the protrusion 1111, with the screw head positioned on the baffle 14. Through the cooperation of the protrusions 1111 and the screw, the counterweight 7 is firmly fixed within the receiving cavity 111, ensuring a tight abutment between the baffle 14 and the counterweight, further improving the stability of the counterweight 7. Even when the toy car is subjected to a large external impact, the counterweight 7 is not easily loosened or detached, ensuring the normal operation and safety of the toy car. The location of the counterweight 7 between each of the protrusions 1111 ensures that the screw connection point does not interfere with the counterweight.

[0067] In some possible implementations, the high-capacity toy car includes a steering drive mechanism 8. A first inner convex shell 112 and a second inner convex shell 113 are provided on the chassis 11. Both the first inner convex shell 112 and the second inner convex shell 113 protrude towards one side of the car body 12. Both the first inner convex shell 112 and the second inner convex shell 113 have receiving cavities. The protrusion height of the first inner convex shell 112 is less than that of the second inner convex shell 113. The receiving cavity in the first inner convex shell 112 is used to accommodate a counterweight 7, and the receiving cavity in the second inner convex shell 113 is used to accommodate a battery 5. The steering drive mechanism 8 is disposed on the first inner convex shell 112. The steering drive mechanism 8 is driven in conjunction with the front wheel 2 to adjust the swing angle of the front wheel 2. This arrangement allows the weight of the steering drive mechanism 8 and the counterweight to simultaneously balance the weight of the high-capacity battery 5, providing dedicated storage space for the battery 5 and the counterweight 7, and also providing a suitable location for the installation of the steering drive mechanism 8, thus making reasonable use of the internal space of the car body 1.

[0068] In some possible implementations, the steering drive mechanism 8 includes a steering cup 81 and a front axle 82. The steering cup 81 is rotatably mounted on the vehicle body 1, and the front axle 82 is rotatably mounted on the vehicle body 1. Two front wheels 2 are respectively connected to the two ends of the front axle 82 and are drively connected to the drive shaft 42. The front wheels 2 are connected to a connector sleeve 83, which has a connecting groove 831. The inner wall of the connecting groove 831 has grooves 832 on opposite sides. The end of the front axle 82 is provided with a ball head 821, and two pillars 8211 are respectively provided on opposite sides of the ball head 821. The two pillars 8211 extend to the two grooves 832 of the connecting groove 831. The steering cup 81 is sleeved on the outside of the connector sleeve 83, and the steering drive mechanism 8 and the steering cup 81 are drively engaged. When a turn is needed, the steering drive mechanism 8 is activated, driving the steering cup 81 to rotate via a transmission mechanism. Since the steering cup 81 is fitted onto the outside of the connector sleeve 83, it in turn drives the connector sleeve 83 to rotate. The connector sleeve 83 is connected to the front wheel 2, so the front wheel 2 changes its swing angle as the connector sleeve 83 rotates, thus achieving the steering operation of the toy car. This ingenious steering structure design, through the close cooperation between various components, can precisely control the steering angle of the front wheel 2, allowing the toy car to flexibly change direction during driving, greatly enhancing the toy car's maneuverability and fun.

[0069] In some possible implementations, the steering drive mechanism 8 includes a second motor 84, a gear train 85, and a sliding frame 86. The sliding frame 86 is slidably mounted on the chassis 11 and is driven by two steering cups 81. The second motor 84 is connected to the input gear of the gear train 85, and the output gear of the gear train 85 is provided with a rocker arm 87. The rocker arm 87 is driven by the sliding frame 86 to drive the sliding frame 86 to reciprocate. When the second motor 84 starts, its power is transmitted to the input gear of the gear train 85 through the transmission connection, and the gear train 85 begins to operate. The rocker arm 87 on the output gear of the gear train 85 oscillates in a circular motion as the gear train 85 rotates, and the oscillation of the rocker arm 87 is further converted into the reciprocating sliding of the sliding frame 86. Since the sliding frame 86 is driven by the two steering cups 81, the reciprocating sliding of the sliding frame 86 will drive the two steering cups 81 to rotate synchronously, thereby realizing the synchronous steering of the front wheels 2, enabling the toy car to smoothly complete the steering action. This steering drive mechanism 8, through the combination of a motor, wheel system 85 and sliding frame 86, achieves precise control over the steering of the front wheels 2, improving the steering flexibility and stability of the toy car.

[0070] In some possible implementations, the drive mechanism 4 includes a rear axle 43 rotatably mounted on the vehicle body 1, two rear wheels 3 respectively connected to the two ends of the rear axle 43, a bevel gear ring provided in the middle of the rear axle 43 and the middle of the front axle 82, and bevel gears provided at both ends of the drive shaft 42, with the two bevel gears meshing with the two bevel gear rings respectively.

[0071] In some possible implementations, the high-powered toy car includes a mounting frame 9. The mounting frame 9 is detachably connected to the car body 1. The mounting frame 9 has connecting holes, through which one end of a fastener passes and connects to the motor, while the other end of the fastener is confined within the mounting frame 9. The design of the mounting frame 9 provides a stable support structure for the motor, ensuring that the motor will not shift due to vibration or external forces during the operation of the toy car. The fastener passing through the connecting holes tightly connects the motor to the mounting frame 9, ensuring a secure connection and extending its service life.

[0072] In some possible implementations, the high-powered toy car includes a protective cover 6, which is detachably connected to the chassis 11. The protective cover 6 is fitted against the peripheral wall of the motor, and a heat dissipation vent 61 is provided on the protective cover 6. The design of the protective cover 6 provides all-round protection for the motor, effectively preventing damage to the motor from external factors such as collisions and dust during the operation of the toy car. Its structure, which fits against the peripheral wall of the motor, not only saves space but also ensures a tight fit between the protective cover 6 and the motor, further enhancing the protective effect. At the same time, the heat dissipation vent 61 on the protective cover 6 can ensure that the heat generated by the motor can be dissipated in a timely manner while protecting the motor, avoiding the impact of overheating on the motor's performance and lifespan.
