[0005]In this invention, auxiliary vehicles are placed in different locations. The main vehicle is remotely controlled to move to the position of the auxiliary vehicle, causing its lower rectangular channel to cover the auxiliary vehicle. When proximity sensors on both sides of the channel detect one end of the auxiliary vehicle, the telescopic shaft of the relay-type electromagnetic shaft box retracts. After a state delay, when the proximity sensor detects the other end of the auxiliary vehicle, the telescopic shaft extends outward, engaging a recess on the top surface of the auxiliary vehicle, connecting it to the main vehicle's channel. The main vehicle then tows the auxiliary vehicle. Subsequently, after a second auxiliary vehicle enters the rectangular channel from the front of the main vehicle, the main vehicle's sensors and electromagnetic shaft box repeat the above actions. The telescopic shaft detaches from the first auxiliary vehicle and connects to the second. Simultaneously, the rear magnet of the second auxiliary vehicle attracts the front magnet of the first auxiliary vehicle, linking the two auxiliary vehicles together and causing them to move with the main vehicle. As the chain of auxiliary vehicles pulled by the main vehicle extends, a "dragon's tail" shaped mother-child chain effect is formed. This invention features a channel structure running through the front and rear ends of the vehicle's base plate. The width of the channel is greater than the width of the auxiliary vehicle but not excessively wide, forming a "limiting" fit. The structure is novel and simple. Furthermore, the process of the main vehicle "absorbing" the auxiliary vehicle during use requires no overly complex manipulation, making it suitable for young children.

Description

Technical Field

[0001] This utility model belongs to the field of toy products, especially remote-controlled electric toy cars. Background Technology

[0002] Remote-controlled electric toy cars for children are a long-standing product category. They use a handheld wireless remote control to manipulate the toy car, allowing it to perform various movements and shape changes, creating a game-like experience. Currently, most children's toy cars on the market emphasize their movement functions, realistic appearance, and structural shape changes, attracting players who value action and novelty, especially IP-based toys. Control-type toys, because they require more skill to fully utilize their functions, often have a wider variety compared to adult toys. In a children's toy market that is becoming increasingly refined and focused on functionality, providing young children with car-type toys that offer simple operation and high levels of fun undoubtedly has a large demand base. This is also what toy manufacturers are focusing on and pursuing. Utility Model Content

[0003] The purpose of this invention is to provide a mother-and-child towable toy car system, consisting of a main car and auxiliary cars connected together. The main car has a structure that allows the auxiliary cars to enter and connect, enabling the auxiliary cars to move with the main car. When the auxiliary cars approach each other, they can be connected end-to-end via magnetic elements. Multiple auxiliary cars can be connected to form a line and towed by the main car. This combined toy car system uses a remote control component to work with the control circuits inside the main car and auxiliary cars for remote control operation. Through a simple structural design, it mimics the natural phenomenon of snakes swallowing food, achieving a new game mode that differs from existing electronic toy cars.

[0004] To achieve the above objectives, the technical solution of the present invention is a mother-and-child towable toy car system, comprising a main vehicle, at least two auxiliary vehicles, and a remote control. The main vehicle's chassis floor forms a longitudinally penetrating rectangular channel, the width of which is greater than the width of the auxiliary vehicles. Proximity sensors are installed on the sidewalls of the channel. A relay-type electromagnetic shaft box is installed on the chassis floor behind the proximity sensors, with the telescopic shaft of the shaft box arranged downwards. A recess is formed in the center of the top surface of the auxiliary vehicle's compartment, the distance between the recess and the end of the auxiliary vehicle being equal to the distance between the main vehicle's proximity sensor and the telescopic shaft of the relay-type electromagnetic shaft box. Magnets are installed at both ends of the auxiliary vehicles.

[0005] In this invention, auxiliary vehicles are placed in different locations. The main vehicle is remotely controlled to move to the position of the auxiliary vehicle, causing its lower rectangular channel to cover the auxiliary vehicle. When proximity sensors on both sides of the channel detect one end of the auxiliary vehicle, the telescopic shaft of the relay-type electromagnetic shaft box retracts. After a state delay, when the proximity sensor detects the other end of the auxiliary vehicle, the telescopic shaft extends outward, engaging a recess on the top surface of the auxiliary vehicle, connecting it to the main vehicle's channel. The main vehicle then tows the auxiliary vehicle. Subsequently, after a second auxiliary vehicle enters the rectangular channel from the front of the main vehicle, the main vehicle's sensors and electromagnetic shaft box repeat the above actions. The telescopic shaft detaches from the first auxiliary vehicle and connects to the second. Simultaneously, the rear magnet of the second auxiliary vehicle attracts the front magnet of the first auxiliary vehicle, linking the two auxiliary vehicles together and causing them to move with the main vehicle. As the chain of auxiliary vehicles pulled by the main vehicle extends, a "dragon's tail" shaped mother-child chain effect is formed. This invention features a channel structure running through the front and rear ends of the vehicle's base plate. The width of the channel is greater than the width of the auxiliary vehicle but not excessively wide, forming a "limiting" fit. The structure is novel and simple. Furthermore, the process of the main vehicle "absorbing" the auxiliary vehicle during use requires no overly complex manipulation, making it suitable for young children. It is an innovative toy car product.

[0006] Even better, in the aforementioned mother-and-child towed toy car system, the proximity sensors are paired infrared sensors or capacitive sensors.

[0007] Pairs of infrared sensors or capacitive sensors can accurately detect changes in the position of the auxiliary vehicle passing through the channel, triggering the main vehicle's control circuit to automatically extend or retract the telescopic shaft of the relay-type electromagnetic shaft box, thereby accurately engaging or disengaging with the auxiliary vehicle.

[0008] Furthermore, in the aforementioned mother-and-child towed toy car system, the magnets at both ends of the secondary vehicle are electromagnetic components, and their magnetism is controlled by a circuit device installed inside the secondary vehicle.

[0009] The two ends of the auxiliary vehicles use electromagnetic components, which are controlled by a control circuit. As needed during the game, the auxiliary vehicles can be connected by a remote control to attract each other, or the magnetism can be lost when the power to the electromagnetic components is turned off, allowing the connected auxiliary vehicle chain to be separated at any time, thus providing another way to play the game and enriching the product's functionality.

[0010] This invention innovates the composition of children's toy cars, creating a new play function. Based on a basic structure, the main vehicle can be designed with the appearance of various animals or objects, increasing the product's fun. This mother-and-child towable toy car system eliminates the need for complex shapes and structures, making production and assembly easy and reducing production costs. The product's structure is compact, its movements are accurate, and the cleverly designed functional structures of the main and auxiliary vehicles, including the arrangement of channels and detection elements, allow for simple operation of the auxiliary vehicle, providing a level of playability not found in existing single-unit toy cars.

[0015] Figure 5 This is a usage status diagram of the remote control toy car system in an embodiment. Detailed Implementation

[0016] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017] As attached Figure 5 A dinosaur model towable toy car system, comprising a main vehicle 1, four auxiliary vehicles 2, and a remote control.

[0018] The structure of the main vehicle is as follows Figure 1 As shown, the system includes a base plate 10, a dinosaur model shell 11, wheels 12 mounted on the base plate, and various electronic components and circuit board assemblies. The base plate forms a longitudinally penetrating rectangular channel 100. A pair of infrared proximity sensors 13 are installed at corresponding positions on the two side walls of the channel, capable of detecting objects passing through the channel. A relay-type electromagnetic shaft box 14 is installed on the base plate behind the proximity sensors. (See attached diagram.) Figure 2The electromagnetic shaft box consists of a housing 140 and a compression spring 141, a shaft 142, and a telescopic shaft 143 installed inside the housing. The shaft of the electromagnetic shaft box is connected to a solenoid valve, which controls the up-and-down movement of the shaft. Simultaneously, the spring 141, in conjunction with the shaft, causes the telescopic shaft 143 to extend and retract. The telescopic shaft 143 of the electromagnetic shaft box is arranged downwards, extending out of the base plate as the shaft moves up and down, and can also retract upwards under the spring's restoring force. The main body of the machine houses conventional electronic toy components such as a power supply and control circuit board, and a drive motor, forming a control device controlled by a remote control signal.

[0019] The structure of subcar 2 is shown in the attached figure. Figure 3 As shown, a recess 20 is formed in the middle of the top surface of the carriage. The distance between the recess and the end of the auxiliary vehicle is equal to the distance between the proximity sensor of the main vehicle and the telescopic shaft of the relay-type electromagnetic axle box. Magnet blocks are installed at the front and rear of the auxiliary vehicles. When the ends of each auxiliary vehicle approach each other, they can attract each other to form a connection. Multiple auxiliary vehicles can be connected in series to form a sub-platform.

[0020] The game uses a toy car system where the main car "devours" the secondary car; see attached image. Figure 4 That is, the auxiliary vehicles are placed separately. The player uses a remote control to move the main vehicle, approaching the first auxiliary vehicle and causing it to enter the channel 100 from the front of the main vehicle. When one end of the auxiliary vehicle is detected by the proximity sensors 13 on both sides of the channel wall, the control circuit causes the telescopic shaft 143 of the relay-type electromagnetic shaft box to retract. After holding and delaying, when the proximity sensor detects the other end of the auxiliary vehicle, the telescopic shaft extends outward again, locking the recess 20 on the top surface of the auxiliary vehicle, connecting the auxiliary vehicle to the main vehicle. The main vehicle then drags the auxiliary vehicle. Subsequently, the main vehicle continues to move and connects to the second auxiliary vehicle. The sensor 13 and electromagnetic shaft box 14 of the main vehicle repeat the above actions, causing the telescopic shaft 143 to detach from the first auxiliary vehicle and connect to the second auxiliary vehicle. At the same time, through the mutual attraction of the magnets at the ends of the auxiliary vehicles, the second auxiliary vehicle is connected to the first auxiliary vehicle in series, forming a chain that moves with the main vehicle. Repeating the above actions, all the auxiliary vehicles are connected and move under the drag of the main vehicle, creating the "dragon tail" game effect. (See attached image) Figure 5 The state.

[0021] In this embodiment, the magnet element at the end of the auxiliary vehicle can also be an electromagnetic element, and a control circuit can be installed to make the electromagnetic element generate magnetism as needed under control to connect the auxiliary vehicle. Alternatively, the power supply to the electromagnetic element can be disconnected by remote control to make the magnetism disappear, allowing the connected auxiliary vehicle chain to be separated at any time. This achieves controllable connection and separation.

[0022] This embodiment can also be a structure where the main vehicle and the controller are connected by a wire for operation, which can also realize the toy car's usage functions and game effects.

[0023] The preferred embodiment of the present invention has been described above with reference to the accompanying drawings, but this does not imply that the structure is limited to the embodiment. Any modifications, equivalent substitutions, and additions falling within the technical scope of the claims of this invention, such as the provision of a multi-channel structure in the main body, and similar structural variations, are also within the technical scope described in this invention.
