Description

Technical Field

[0001] This utility model belongs to the field of toy products, and in particular to electric toy cars with convertible shapes. Background Technology

[0002] With the development of electronic and radio technologies, electric children's toy cars are becoming increasingly functional and intelligently controlled. Examples include model cars scaled down to various functional vehicles, science fiction or creative design toys, and medium-sized toys such as go-karts that combine practicality and intelligence. The structures of these toy cars vary according to their performance characteristics, resulting in diverse product forms. By equipping them with various control mechanisms or radio remote control devices, users can control the toy cars to achieve movement, transformation, and racing performances, creating entertainment effects. Currently, the vast majority of children's toy cars on the market are single-form products. While a few can transform into multiple forms through structural conversion, these changes are limited to altering the product's appearance; the functional effects remain largely unchanged, such as a car transforming into a superhero. Toy car products designed for substantial functional changes and structurally convertible are lacking in production. In a children's toy market that is becoming more refined and focused on functionality, developing products with more integrated functions holds great promise. Utility Model Content

[0003] The purpose of this invention is to provide a foldable catapult toy car that can be refolded and unfolded through the conversion of its movable structure. A modular track structure is installed inside the car body. As the car unfolds, the track structure also reassembles, forming a state where the front end or both the front and rear ends are raised, transforming into a track device with catapult functionality. Combined with the drive of the wheels, the entire toy car body transforms into a platform for launching small toy cars.

[0004] To achieve the above objectives, the technical solution of this utility model is a folding catapult toy car, comprising a car body and four wheels, with a pair of front wheels or a rear wheel connected to a drive motor via a gear set. The car body consists of a frame and a car body cover covering the frame. The front and rear wheels on the same side are mounted on the same wheel frame, and the two wheel frames are hinged to the frame, with each wheel frame having a tongue. A fixed frame is slidably mounted inside the car body, and the tongue can be connected to or detached from the fixed frame. The positions on the wheel frames that fix the wheels form support foot structures. Three track pieces are installed inside the car body, including a track piece hinged at the front and rear ends and a middle track piece. When unfolded, the track pieces are spliced ​​together to form tracks with raised front and rear ends.

[0005] The connection or disconnection of the wheel frame's tongue from the fixed frame can be achieved by setting a snap-fit ​​interface or snap-fit ​​piece on the fixed frame. The tongue contacts or disconnects from the snap-fit ​​interface or snap-fit ​​piece by sliding the fixed frame back and forth. This vehicle structure of the present invention is completely different from the structure of existing convertible toy cars, and has the following characteristics: 1. It features a flip-up wheel frame structure, enabling the toy car to transform into a launch platform. Specifically, when used as a car model, the wheel frame faces downwards, perpendicular to the vehicle's base, with the wheels supporting the vehicle body for normal driving operations. After flipping the wheel frame upwards to a horizontal position, the tongue snaps into the snap-fit ​​part of the fixed frame to form a fixed connection. At this time, the wheels are parallel to the vehicle's base, and the wheel frame's support legs are vertical, serving as components supporting the vehicle body. The four support legs lift the vehicle body and stabilize it. Simultaneously, after flipping, the wheels remain horizontal, symmetrically arranged one in front of the other on both sides of the vehicle's base, with the distance between the wheels on both sides being the same as or slightly wider than the width of the track pieces installed on the vehicle's base. In this way, after the driving wheels are activated, the rolling direction of the wheels generates forward tangential kinetic energy, which is converted into acceleration for the small toy cars sliding and passing on the track. The accelerated small toy cars move forward along the track and are launched from the front, creating a "flying car" effect. 2. The vehicle body cover and the frame base plate are installed using an end hinge. Simultaneously, track plates are installed inside the vehicle body, the frame base plate, and the inner side of the vehicle body cover, creating an innovative structure that transforms the toy car into a launch platform. After the vehicle body cover is flipped around the hinge, the track plates stored inside the vehicle body can also unfold, allowing the three track plates to be joined together to form a complete sliding track, providing movement for the small toy cars and achieving the effect of launching a flying car. Compared with existing toy car structures, this modified structure provides more diverse play performance and enhances product appeal.

[0006] Even better, the aforementioned folding catapult toy car has a wheel frame with a snap-fit ​​piece that connects to an interface hole on the frame. The connection between the snap-fit ​​piece and the interface hole, along with the tongue piece, allows the wheel frame to flip into a car model shape or a catapult shape.

[0007] Alternatively, the wheel frame generates connecting holes, and the fixing frame extends outwards with hooks. The connection between the hooks and connecting holes, along with the tongue, causes the wheel frame to rotate, allowing the toy car to change between the shape of a car model or a catapult.

[0008] The connection between the wheel frame and the fixed frame is the fixed structure for changing the shape of the toy car. This invention uses a snap-fit ​​and interface hole insertion method to position the wheel frame in the aforementioned car model shape, vertically downwards from the car body's base, with the wheels supporting the car body. After flipping the wheel frame upwards, it is fixed to the fixed frame with a tongue, placing the wheel frame in the aforementioned horizontal position. The support legs of the wheel frame support the car body, presenting a launch platform shape. A similar structure can be achieved by using a hook and connecting hole insertion method, which also positions the wheel frame in the aforementioned vertically downwards and fixed state, allowing the toy car to be used in the shape of a car model. Therefore, both structures of this invention provide a stable combination that allows the toy car to freely change shape, and are easy to operate, simple in structure, and have the advantages of low production cost.

[0009] Preferably, in the above-described folding catapult toy car, the gear set for driving the wheels consists of a motor-driven driving wheel meshing with a transmission wheel, and the transmission wheel meshing with a driven gear. The driven gear is fixed to the wheel, and the transmission ratio between the driving gear and the driven gear is 1:1 to 1:1.5.

[0010] This invention's gear set structure solves the problem of existing toy cars having a relatively small drive transmission ratio, resulting in insufficient drive torque to generate enough kinetic energy for the wheels. The transmission ratio between the driving gear and the driven gear is set to 1:1 to 1:1.5, making the wheels and the drive motor rotate at nearly the same speed. At this speed, the torque generated by the two main drive wheels exceeds the requirements for normal vehicle movement, generating greater frictional force for small toy cars passing between them and making contact. This allows the small toy cars to be propelled forward quickly and launched from the catapult platform at a faster speed, achieving a more engaging gaming experience. Furthermore, the smaller transmission ratio also allows the toy car to have higher speeds and more agile steering capabilities.

[0011] Furthermore, the aforementioned folding catapult toy car also includes a small model car. The width of the model car is the same as the width of the track plate and the spacing between the two driving front / rear wheels when the toy car is flipped into a catapult shape. The upper surface of the car body cover has a front block and a rear block. The front block is equipped with a button, which is connected to a support mechanism. The support mechanism has outwardly extending inserts, and the rear block forms fixing holes. The small model car has a front hook plate and a rear hook plate structure, which are connected to the inserts and fixing holes respectively for fixed installation.

[0012] The design utilizes two platforms on the upper part of the vehicle body cover, which work in conjunction with two hook plates on the small model car to stably and securely fix the small model car to the toy car. When used as a model car, it serves a storage function and enhances the product's unique aesthetics. When used as a launcher, pressing the button on the front platform retracts the insert of the front support mechanism, disengaging it from the front hook plates of the small model car. This allows the small model car to be removed and placed on the unfolded track after the wheel frame has been flipped and fixed as a launcher, serving as a launch target. This design embodies the integrated nature of a launcher toy and offers high practicality.

[0013] This invention's wheel frame structure achieves toy car shape transformation in a simple and easy-to-assemble manner. The concealed and easily deployable assembly track structure functions as a launch platform, making it a shape-changing toy product with enhanced fun. Toy cars with this structure can exhibit high speed and changing shapes during play; when converted into a static launch platform, the drive wheels provide the launch mechanism, maintaining a continuous and stable trajectory, significantly improving the playability of drive-type children's toy cars. Furthermore, this invention's structure boasts the advantages of simple and reasonable components, and a compact and stable assembly. Attached Figure Description

[0018] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings.

[0019] As attached Figure 1 A folding catapult toy car includes a main truck A with a convertible structure and a small model car B, the small model car being installed in the cargo compartment of the main truck.

[0020] See appendix Figure 2The main truck consists of a body 1 with four wheels 2. The body includes a frame 3, wheel frames 4, and a cargo box cover 5 that is articulated and covers the frame. A front panel 50 and a rear panel 51 are respectively located on the inner side of the cargo box compartment on the top surface of the cargo box cover, at the front and rear. A button 52 is installed on the top surface of the cargo box cover's cab. A support mechanism is located inside the cargo box cover and includes an insert 53 extending outward from an opening generated in the front panel. The button 52 is connected to the support mechanism; pressing the button retracts the insert inward at the opening. A fixing hole 511 is generated in the rear panel block 51. The small model B has a front hook plate 90 at the front and a rear hook plate structure at the rear. The front hook plate engages with the insert 53, and the rear hook plate is inserted into the fixing hole 511 of the rear panel block for fixed installation.

[0021] The vehicle body structure is as shown in the attached figure. Figure 2 As shown, tilting axles 30 are installed on both sides of the frame 3, and two wheel carriers 4 are hinged to the frame 3 via the axles 30. A fixing bracket 6 is installed inside the frame 3, which can slide back and forth within the frame. A snap-fit ​​piece 60 is formed on the fixing bracket, and a wheel carrier connecting tongue 40 is formed. After the wheel carrier is tilted, the tongue is connected and fixed to the snap-fit ​​piece.

[0022] The front wheel 7 and rear wheel 8 are mounted on the open end of the wheel frame. The front support foot 70 is connected to the inside of the front wheel, and the drive assembly box 80 is connected to the inside of the rear wheel. See the appendix for the specific structure of the drive assembly box. Figure 4 The system includes a housing 800 and a drive motor 801 and a gear set 802 installed within the housing. The drive gear set consists of a driving gear 8021 meshing with a transmission gear 8022, and the transmission gear meshing with a driven gear 8023. The driven gear is fixedly connected to the wheel, and the transmission ratio between the driving gear and the driven gear is 1:1.1. The drive assembly box 80 serves as a rear support leg after the wheel frame is deployed, cooperating with the front support legs to support the entire vehicle body. (See attached...) Figure 3 As shown, an ejection track consisting of three sections is installed inside the vehicle body: a front track section 10, a middle track section 11, and a rear track section 12. The rear track section is attached to the back of the cargo box cover, the middle track section is mounted on the frame 3, and the front track section 10 and the middle track section are hinged and can be flipped forward and unfolded. After unfolding, the ejection track is in a state where the front and rear ends are raised.

[0023] See the attached image for the toy car unfolded into a catapult platform. Figure 3 Remove the small model car from the cargo box cover, flip the cargo box cover backward, and then unfold the track plate. Then, turn on the power to drive the two rear wheels to rotate, thus creating a catapult-driven mode. During gameplay, place the small model car at the end of the rear track plate 12 and let it roll down naturally. As it passes between the two rear wheels, its sides are propelled by the high-speed rotating rear wheels, generating acceleration and propelling it out at high speed from the front of the front track plate, achieving the catapult-like effect.

[0024] This embodiment can also be set to front-wheel drive or four-wheel drive mode. When set to four-wheel drive, the enhanced launch effect can be achieved.

[0025] The above description, with reference to the accompanying drawings, illustrates a preferred embodiment of the present invention, but does not imply limitation to the structure of the embodiment. Any modifications, equivalent substitutions, and additions falling within the technical scope of the claims of this utility model, such as the connection and fixing method between the vehicle body mounting bracket and the wheel frame, using other detachable snap-fit ​​structures, such as snap-fit ​​pieces with matching interface holes, or hook pieces with matching connection holes, and similar structural variations, are also within the technical scope described in this utility model.
