[0007] As a preferred embodiment, the interlocking structure includes a detachable interlocking slot and an interlocking block. The interlocking slot is constructed within a post extending toward the top plate in the base plate, and the interlocking slot is exposed on the top plate. The interlocking block protrudes from the interlocking slot on the opposite side of the base plate away from the top plate.

[0008] As a preferred embodiment, the top surface of the vehicle body is provided with a splicing slot and / or splicing block for detachable engagement with any of the track plates. The vehicle body is recessed with an initial track extending through to one side. A launching device is provided on the initial track. The vehicle body is provided with a splicing groove and / or splicing block for detachable engagement with any of the track plates on the outer side of the opening of the initial track.

[0009] As a preferred embodiment, the base plate is a quadrilateral plate structure with positioning platforms at its four apex corners. Each positioning platform contains a pin. A connecting block of the top plate is elastically hinged between a pair of positioning platforms.

[0010] As a preferred embodiment, the vehicle body includes a vehicle panel, a front end fixed to the vehicle panel, and side wings respectively hinged to both sides of the vehicle panel. The front end is provided with an on / off switch that can be flexibly moved. The on / off switch is provided with two first buckles facing each other. The side wings are provided with second buckles that can be engaged with the first buckles. When the second buckles are engaged with the first buckles, the two side wings are vertically connected to both sides of the vehicle panel. When the on / off switch moves to separate the first buckles and the second buckles, the two side wings can be rotatably unfolded to both sides of the vehicle panel.

[0011] As a preferred embodiment, the vehicle body has at least one recessed storage slot for storing toy cars, and the vehicle body also includes multiple sets of wheels rotatably connected to the vehicle body, one set of which is driven to rotate by a drive gearbox, and the drive gearbox is fixedly installed inside the vehicle body.

[0012] As a preferred embodiment, the vehicle head has the shape of an animal skull, and the vehicle head includes a lower jaw fixedly connected to the vehicle body and an upper jaw rotatably connected to the lower jaw. The upper jaw has a circuit assembly fixedly installed inside, and the circuit assembly includes a circuit board electrically connected to the motor of the drive gearbox.

[0013] As a preferred embodiment, the system further includes a termination plate, which is detachably fixed to the vehicle body or the track plate via the interlocking structure. The termination plate includes a base and a flip plate. The base has a recessed termination track extending to one side. The base has a splicing groove and / or splicing block on the outside of the opening of the termination track for detachable engagement with any of the track plates. The flip plate is elastically hinged to the base via a rotating arm. The base has an elastically movable locking element inside, which includes a locking rod and a trigger rod extending into the termination track. The locking rod is used to lock the flip plate onto the base. When the trigger rod is moved by force, the locking rod can separate from the flip plate, allowing the flip plate to rotate and stand upright on the base.

[0014] Therefore, based on the technical means of this utility model, the effects that this utility model can achieve are briefly described as follows: Multiple track plates of the novel explosive splicing track car provided by this utility model can be housed and fixed on the car body. Simultaneously, any track plates can be arbitrarily assembled through the structure of splicing slots and interlocking blocks, thus giving the track car the advantage of variable and versatile track routes. Furthermore, each track plate includes a bottom plate and a top plate that are elastically hinged. The top plate is locked to the bottom plate by a locking member. Since the locking rod of the locking member is located on the passageway of the top plate, the locking rod can be moved by the toy car during the passageway to release the top plate, allowing the top plate to rotate and tilt onto the bottom plate, thereby enabling the top plate to tilt and slide the toy car to the next track plate. It can be seen that the track plates provided by this utility model can also change shape during play, further enriching the diversity of track variations, while increasing the fun and interactivity of the game, helping to improve the entertainment value of the track car and attracting children to play.

The terminology used in this specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0028] Please refer to the following at the same time Figure 1-10 This embodiment provides a novel split-joint railcar, including a car body 1, and multiple track slabs 2 detachably housed on the car body 1 and a termination plate 3. Of course, in other embodiments, the railcar may only include the car body 1 and multiple track slabs 2.

[0029] In this embodiment, the vehicle body 1 is a toy transport vehicle, including a platform 11, a front end 12 fixed to the platform 11, side wings 13 respectively hinged to both sides of the platform 11, and multiple sets of wheels 14 rotatably connected to the platform 11. The platform 11 has at least one recessed storage slot 111 for storing the toy vehicle. The vehicle body 11 is detachably fixed to the track plate 2 via an interlocking structure. It is understood that the interlocking structure includes detachably engaging slots 41 and interlocking blocks 42; therefore, the top surface of the platform 11 also has slots 41 (and / or interlocking blocks 42) for detachably engaging with any track plate 2. It is understood that the length of the vehicle body 11 is an integer multiple of the length of the track plate 2. The platform 11 has a recessed initial track 112 extending to one side, and the initial track 112 has a launching device 113 for launching the toy vehicle out of the initial track 112. The launching device 113 includes a snap-fit ​​start button 1131 and a push plate 1132. Pressing the start button 1131 releases the push plate 1132, allowing it to propel the toy car forward under elastic force. It should be noted that since the above-described structure of the launching device 113 is already disclosed in the prior art, its structural details and working principle will not be described in detail here. To ensure that the initial track 112 can stably connect to the passageway on the track plate 2, the vehicle plate 11 is also provided with a splicing block 225 (and / or splicing groove 224) on the outside of the opening of the initial track 112 for detachable engagement with any track plate 2. Of course, in other embodiments, the vehicle body 1 can be designed as a simple storage structure for multiple track plates 2, etc. In this case, the appearance of the vehicle body 1 can be adjusted according to design requirements, and the vehicle body 1 may not have side wings 13, wheels 14, or other related structures. The platform 11 may only have the function of storing toy cars. Therefore, the platform 11 may not have the initial track 112, launching device 113 and other related structures. In this case, the toy car can be launched by manually pushing the toy car to move.

[0030] The front of the vehicle 12 has the shape of an animal skull; in this embodiment, it has the shape of a dinosaur skull. The front of the vehicle 12 includes a lower jaw member 121 fixedly connected to the vehicle body 11 and an upper jaw member 122 rotatably connected to the lower jaw member 121. This structure allows players to simulate the opening and closing of a dinosaur's mouth by rotating the upper jaw member 122, increasing fun and attracting children's attention. It is understood that a circuit assembly 123 is fixedly installed inside the upper jaw member 122. The circuit assembly 123 includes a circuit board 1231 electrically connected to the motor of the drive gearbox 15, and a speaker 1232, function switches 1233, and a battery, all electrically connected to the circuit board 1231. Multiple function switches 1233 are used to control different functions, such as starting the power supply, starting the drive gearbox 15, and starting the speaker 1232. Of course, in other embodiments, the appearance and structural fixing method of the front of the vehicle 12 can be adaptively adjusted according to the overall appearance design requirements of the track vehicle. The circuit assembly 123 may not be installed inside the front of the vehicle. Correspondingly, the circuit structure of the circuit assembly 123 can be adapted to meet the design requirements.

[0031] It should be noted that a switch 124 is flexibly movable on the front 12. The switch 124 is exposed on the front 12 and has two first latches 1241 facing each other thereon, used to lock or release the side wings 13. Correspondingly, the side wings 13 are provided with second latches 131 that can be engaged with the first latches 1241. When the second latches 131 are engaged with the first latches 1241, the two side wings 13 are vertically connected to both sides of the platform 11, defining a space for fixing and connecting the track plate 2 together with the platform 11, which can improve the storage safety, fun of use, and aesthetics of the toy. When the switch 124 is moved by force to separate the first latches 1241 and the second latches 131, the two side wings 13 can rotate and unfold to both sides of the platform 11, so as to facilitate the installation and removal of the track plate 2 on the platform 11, increasing the ease of use of the toy. Of course, in other embodiments, if the railcar does not have a side wing 13 or the side wing 13 is fixed on the car plate 11, then the switch 124 may not be provided on the car head 12.

[0032] Wheels 14 enable the vehicle body 1 to move on a plane. One set of wheels 14 is driven to rotate by a drive gearbox 15, which is fixedly installed inside the vehicle plate 11. In this embodiment, the drive gearbox 15 consists of a motor and drive gears, used to drive the vehicle body 1 to move automatically. To improve the appearance coordination and overall fun of the vehicle body 1, two front limbs 16 and two rear limbs 17 are rotatably connected to the front and rear sides of the vehicle body 11, respectively. The front limbs 16 and rear limbs 17 are designed in the shape of dinosaur limbs, so that the vehicle body 1 has a vehicle body form with wheels 14 on the ground and a biomimetic form with front limbs 16 and rear limbs 17 on the ground. Of course, in other embodiments, the drive gearbox 15 can adopt other existing drive gearbox structures, such as a drive gearbox with a spring as the power source or a drive gearbox with a flywheel as the power source. The front limbs 16 and rear limbs 17 may not be provided on the vehicle body 11.

[0033] Multiple track plates 2 are detachably stacked and fixed to the vehicle body 11 via an interlocking structure. Since the interlocking structure includes detachably engaging slots 41 and interlocking blocks 42, the slots 41 are optionally constructed on the side where the top plate of the track plate 2 is located, and the interlocking blocks 42 protrude from the slots 41 on the opposite side of the bottom plate of the track plate 2, opposite to its top plate. In other words, each track plate 2 includes a top plate 21 and a bottom plate 22. One side of the top plate 21 is elastically hinged to the bottom plate 22 via a torsion spring or other elastic element, allowing each track plate 2 to change shape during the toy car's movement, thereby increasing the toy's versatility, interactivity, and fun, and enhancing its entertainment value.

[0034] One side of the top plate 21 is provided with a connecting block 211, which is used to elastically hinge the top plate 21 to the bottom plate 11. A through-track 212 extending outwards is recessed on the top plate 21, which is used for toy cars to slide through. In this embodiment, to ensure the toy car can smoothly enter the through-track 212, a corresponding limiting plate 213 is provided on the inner wall at the entrance of the through-track 212 to prevent the toy car's front from lifting up or even derailing when it slides into the through-track 212. Of course, in other embodiments, the limiting plate 213 may not be provided in the through-track 212. It should be noted that in this embodiment, an opening 214 is also provided in the top plate 21 at a position corresponding to the assembly slot 41. The opening 214 allows the assembly slot 41 to be exposed on the top plate 21, so as to realize the stacking and splicing of any two track plates 2.

[0035] It is understood that the base plate 22 is a quadrilateral plate structure with positioning platforms 221 at each of its four apex corners. Each positioning platform 221 has a pin 222 inside, the end of which is exposed in the opening 214 and recessed to form a splicing slot 41. A connecting block 211 is elastically hinged between a pair of positioning platforms 221, and the sidewalls of the two positioning platforms 221 with the connecting block 211 can abut against the wall of the top plate 21 to limit the rotation angle of the top plate 21 and prevent the top plate 21 from rotating too much and affecting the normal movement of the toy car. The base plate 22 has a fixing seat 223 inside for fixing and installing the locking component 23, and the base plate 22 has splicing grooves 224 and splicing blocks 225 on the outside of the two openings of the passage track 212 for detachable engagement with another track plate 2. It should be noted that, according to design requirements, the splicing groove 224 and the splicing block 225 can be separately installed on the two track plates 2, or the splicing groove 224 and the splicing block 225 can be simultaneously installed on the same side of the same track plate 2. The splicing groove 224 and the splicing block 225 are detachably connected, and the structural configuration of the splicing groove 224 and the splicing block 225 can be used to achieve detachable fixing between any two track plates 2, detachable fixing between the track plate 2 and the vehicle plate 11, and detachable fixing between the track plate 2 and the termination plate 3.

[0036] The locking member 23 is elastically and movablely connected to the fixed base 223 via a spring or other elastic element. The locking member 23 includes a locking rod 231 that extends into the passageway 212. The locking rod 231 has a locking part, which allows the locking rod 231 to move under the elastic drive to a position that locks the top plate 21 onto the bottom plate 22. When the locking rod 231 moves under the push of the toy car, its locking part moves to separate from the top plate 21, allowing the top plate 21 to rotate and tilt onto the bottom plate 22, thereby completing the shape change of the track plate 2. At the same time, during the rotation of the top plate 21, the toy car on the passageway 212 can be rotated and brought into the passageway 212 of another track plate 2, allowing the toy car to continuously slide to the next track plate 2.

[0037] It should be noted that the track board 2 includes a straight track board 2a and a curved track board 2b. The straight track board 2a has a straight travel track 212, and the curved track board 2b has a curved travel track 212. Different shapes of track routes can be built using the straight track board 2a and the curved track board 2b, enriching the track building gameplay. It can be understood that the curved track board 2b has a locking bar 231 at the inflection point of its travel track, and the travel track of the curved track board 2b has a structure that is narrow at both ends and wide in the middle in the direction of travel. This is used to restrict the movement trajectory of the toy car, so that the toy car can hit the moving locking bar 231 after entering the curved track board 2b, and then slide to the next track board 2 as the top plate 22 rotates.

[0038] The termination plate 3 is used to provide feedback to the player that the toy car has reached the finish line. It is understood that the termination plate 3 is also detachably fixed to the car body 1 or the track plate 2 via the aforementioned interlocking structure. Therefore, the two opposite sides of the termination plate 3 are also provided with interlocking slots 41 and interlocking blocks 42. The termination plate 3 includes a base 31 and a flip plate 32. The base 31 has a recessed termination track 311 extending to one side. The base 31 has an interlocking groove 224 (and / or interlocking block 225) on the outside of the opening of the termination track 311 for detachable engagement with any track plate 2. The flip plate 32 is elastically hinged to the base 31 via a rotating arm 321. The flip plate 21 is locked by a locking member 33 elastically moved inside the base 31. Specifically, a latching plate 322 extends from the side wall of the flip panel 32 toward the base 31. The locking element 33 includes a locking rod 331 and a trigger rod 332 that extend into the termination track 311. The locking rod 331 is snap-fitted to the latching plate 322 to lock the flip panel 32 onto the base 31. When the toy car moves into the termination track 311 and strikes the trigger rod 332, the locking rod 331 moves to separate from the latching plate 322, allowing the flip panel 32 to be driven by a spring force to rotate and stand upright on the base 31, indicating that the toy car has reached the finish line.

[0039] Therefore, the track vehicle provided in this embodiment has a variable and varied track route. At the same time, during the game, both the track plate 2 and the end plate 3 can change shape, which can enrich the game variations of the track toy, increase the game's interactivity and fun, and improve its entertainment value.

[0040] 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.
