[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a transport vehicle toy, which includes a body 1 and a door assembly 2. The body 1 includes a floor 11 for carrying cargo models. The body 1 has at least one opening 12 communicating with the outside world for the cargo models to pass through. The floor 1 is inclined toward the opening 12, with the end of the floor 11 away from the opening 12 higher than the end near the opening 12 in the direction of gravity. The door assembly 2 is used to selectively open or close the opening 12. Specifically, the floor 11 is configured with an inclined structure, wherein the end away from the opening 12 is higher than the end near the opening 12 in the direction of gravity. This design allows the cargo models to automatically move toward the opening 12 under the action of gravity. When the cargo model is carried in the body of the transport vehicle toy, the inclined placement of the floor 11 toward the opening 12 facilitates the direct sliding of the cargo model out of the opening 12, making unloading easier and increasing the fun.

[0033] Please continue reading. Figure 2 and Figure 4 The container body 1 also includes a first rolling element 13, which is connected to the bottom plate 11 and faces the cargo model. The first rolling element 13 is rotatable about a fixed axis and includes a curved surface (not shown) that protrudes from the bottom plate 11. Specifically, the first rolling element 13 is rotatably connected to the bottom plate 11 and is positioned facing the cargo model. The first rolling element 13 achieves its rotation function through the fixed axis, and its curved surface structure protrudes outward relative to the bottom plate 11. The curved surface design allows the first rolling element 13 to provide guidance when it contacts the cargo model, reducing sliding friction. In one embodiment, the first rolling element 13 can be a roller structure, with the roller surface further covered with a rubber layer to enhance friction. In another embodiment, the first rolling element 13 can be a bearing. By providing a first rolling element 13 with a convex curved surface, the cargo model can form point or line contact with the first rolling element 13 during movement, effectively reducing frictional resistance and improving the smoothness of the cargo model's movement. The curved surface structure can automatically compensate for minor displacement deviations in the cargo model, avoiding jamming caused by installation errors and facilitating the smooth sliding out of the cargo.

[0034] Please continue reading. Figure 4 and Figure 5The axial direction of the first rolling element 13 is angled to the inclination direction of the base plate 11, ensuring that the sliding direction of the cargo model has at least a component towards the opening 12. Specifically, there is a specific angle between the axial direction of the first rolling element 13 and the inclination direction of the base plate 11. This angle design ensures that the sliding trajectory of the cargo model under gravity includes at least one motion component towards the opening 12. Simultaneously, the inclination direction of the base plate 11 typically forms an angle with the direction of gravity acting on the cargo model. In one embodiment, the specific angle between the axial direction of the first rolling element 13 and the inclination direction of the base plate 11 can be achieved by adjusting the installation position of the first rolling element 13. The sliding direction of the cargo model can be directionally moved through the guiding action of the first rolling element 13 and its cooperation with the inclined surface of the base plate 11. By setting a specific angle between the axial direction of the first rolling element 13 and the inclination direction of the base plate 11, the cargo model can automatically slide towards the opening 12 when subjected to external forces. This design reduces resistance during cargo unloading and improves operational efficiency.

[0035] Please continue reading. Figure 2 and Figure 4 There are multiple first rolling elements 13, whose axial directions are parallel to each other and are spaced apart in directions parallel to and / or perpendicular to the axial directions of the first rolling elements 13. Specifically, the arrangement of multiple first rolling elements 13 with parallel axial directions ensures that the first rolling elements 13 roll in the same direction. In one embodiment, the first rolling elements 13 may be spaced apart in a direction parallel to their own axial direction, i.e., multiple first rolling elements 13 are spaced apart in the direction in which the toy is moving in the transport vehicle; in another embodiment, the first rolling elements 13 are spaced apart in a direction perpendicular to their axial direction, i.e., multiple first rolling elements 13 are spaced apart in the direction in which the toy model falls. In one embodiment, as... Figure 2 As shown, multiple first rolling elements 13 are spaced apart in both directions parallel and perpendicular to their own axis, improving the stability of the cargo model during its descent. This spaced arrangement of multiple first rolling elements 13 optimizes space utilization, avoids interference between the rolling elements, and ensures uniform force distribution. This spaced arrangement of multiple first rolling elements 13 allows the toy transport vehicle to maintain higher stability during descent. Simultaneously, the multi-point support layout helps to distribute weight pressure and extend the lifespan of the toy vehicle.

[0036] Please continue reading. Figure 2 and Figure 4 The base plate 11 has an angle between 3° and 10° with the horizontal direction. Specifically, the base plate 11 is the main load-bearing structure for transporting toy vehicles, and it forms an inclination angle of 3° to 10° with the horizontal direction. Specifically, the angle can be 3, 4, 5, 6, 7, 8, 9, or 10°. The inclined design of the base plate 11 can assist the cargo model to slide down under the action of gravity.

[0037] Please continue reading. Figure 2 and Figure 5 The body 1 also includes a support plate 14 and an angle adjustment assembly 15. The support plate 14 is located on the side of the bottom plate 11 away from the cargo model, and the side of the support plate 14 near the door panel assembly 2 is movably connected to the bottom plate 11. The angle adjustment assembly 15 is located between the support plate 14 and the bottom plate 11, and is used to adjust the angle between the side of the support plate 14 near the door panel assembly 2 and the side of the bottom plate 11 near the door panel assembly 2. Specifically, the support plate 14 is located on the back of the bottom plate 11 away from the cargo model, and its side near the door panel assembly 2 forms a movable connection structure with the bottom plate 11, which can be achieved by using a hinge or a pivot to allow the bottom plate 11 to rotate relative to the support plate 14. At the same time, an angle adjustment component is provided between the support plate 14 and the bottom plate 11 to adjust the included angle between the support plate 14 and the bottom plate 11. The connection method between the angle adjustment assembly 15 and the support plate 14 can be mechanical, magnetic, or hydraulically damped, and the specific selection needs to be determined according to the load-bearing requirements and adjustment accuracy requirements of the actual use scenario. The angle adjustment component 15 allows the angle between the support plate 14 and the base plate 11 to be adjusted according to actual usage needs. For example, when loading a cargo model, the tilt angle of the base plate 11 is 0 or small, and when unloading a cargo model, the tilt angle of the base plate 11 relative to the support plate 14 is large.

[0038] Please continue reading. Figure 5 The angle adjustment assembly 15 includes a first driving member (not shown) and a push rod 151. The first driving member is disposed inside the compartment 1. One end of the push rod 151 is connected to the support plate 14, and the other end is connected to the bottom plate 11. Under the drive of the first driving member, the height of the push rod 151 changes. Specifically, the angle adjustment assembly 15 adjusts the rotation angle of the bottom plate 11 through the cooperation of the first driving member and the push rod 151. The first driving member is installed inside the compartment 1. One end of the push rod 151 is connected to the support plate 14, and the other end is connected to the bottom plate 11. The first driving member can drive the length of the push rod 151 to change, thereby changing the height of the side of the bottom plate 11 away from the opening 12, and thus changing the distance between the bottom plate 11 and the support plate 14. For example, when the length of the first driving member driving the push rod 151 increases, the distance between the base plate 11 and the support plate 14 increases on the side away from the opening 12, and at the same time, the tilt angle of the base plate 11 relative to the support plate 14 increases; when the length of the first driving member driving the push rod 151 decreases, the distance between the base plate 11 and the support plate 14 decreases on the side away from the opening 12, and at the same time, the tilt angle of the base plate 11 relative to the support plate 14 decreases. The automatic adjustment of the height of the base plate 11 is achieved through the linkage of the first driving member and the push rod 151, enabling the transport vehicle toy to have a dynamic adjustment function, improving the flexibility of operation and scene adaptability of the transport vehicle toy.

[0039] In one embodiment, the angle adjustment assembly 15 includes a second drive member (not shown) and a lifting plate (not shown). The second drive member is disposed inside the body 1. The lifting plate is located between the support plate 14 and the bottom plate 11, and is located on the side away from the door 21. One end of the lifting plate is connected to the support plate 14, and the other end is connected to the bottom plate 11. The extension direction of the lifting plate is the same as the travel direction of the toy in the transport vehicle. Driven by the second drive member, the height of the lifting plate changes to adjust the angle between the support plate 14 and the bottom plate 11. Specifically, the angle adjustment assembly 15 adjusts the rotation angle of the bottom plate 11 through the cooperation of the second drive member and the lifting plate. The second drive member is installed inside the body 1. One end of the lifting plate is connected to the support plate 14, and the other end is connected to the bottom plate 11. The second drive member can drive the height of the lifting plate to change, thereby changing the height of the bottom plate 11 on the side away from the opening 12, and thus changing the distance between the bottom plate 11 and the support plate 14. For example, when the second driving component increases the height of the lifting plate, the distance between the base plate 11 and the support plate 14 increases on the side away from the opening 12, and the tilt angle of the base plate 11 relative to the support plate 14 also increases. Conversely, when the second driving component decreases the height of the lifting plate, the distance between the base plate 11 and the support plate 14 decreases on the side away from the opening 12, and the tilt angle of the base plate 11 relative to the support plate 14 also decreases. The automatic adjustment of the height of the base plate 11 is achieved through the linkage between the second driving component and the lifting plate, enabling the transport vehicle toy to have dynamic adjustment capabilities and improving the flexibility and adaptability of its operation. Furthermore, the lifting plate, relative to the push rod 151, increases the contact area with the base plate 11, which can reduce the pressure between the lifting plate and the base plate 11 and adjust the load distribution.

[0040] Please continue reading. Figure 1 , Figure 2 and Figure 3 The body 1 includes a side wall 16 with through holes forming an opening 12. At least one end of the side wall 16 forming the opening 12 is provided with a sliding rail 161. The door panel assembly 2 also includes a door 21, a drive assembly (not shown), and a limiting assembly (not shown). The door 21 is slidably connected to the sliding rail 161. The drive assembly is connected to the door 21 and is used to drive the door 21 to move to open or close the opening 12. The limiting assembly is located on the body 1 and is used to limit the range of movement of the door 21. Specifically, the side wall 16 of the body 1 is provided with through holes as openings 12, and the end of the side wall 16 is provided with a sliding rail 161 to guide the door 21 to move. The door 21 achieves linear movement through the sliding rail 161. The drive assembly is used to drive the door 21 to move. When the door 21 moves towards both ends of the body 1, the opening 12 opens; when the door 21 moves towards the middle of the body 1, the opening 12 closes. To further limit the range of motion of the door 21 and prevent it from slipping off the sliding track 161, a limit assembly is provided on the body 1 to limit the range of motion of the door 21.

[0041] Please continue reading. Figure 1 , Figure 2 and Figure 3 The drive assembly includes a third drive member (not shown), a gear 221, and a rack 222. The third drive member is disposed inside the body 1. The gear 221 is connected to the third drive member and is located on the side wall 16 of the body 1 near the door 21. The rack 222 is connected to the side wall 16 of the door 21 near the door 21. The rack 222 and the gear 221 mesh to drive the door 21 to move and open or close the opening 12. Specifically, the drive assembly includes a third drive member installed inside the body 1. The third drive member is connected to the gear 221, which is located on the side wall 16 of the body 1 near the door 21. The third drive member drives the gear 221 to rotate, and through the meshing of the gear 221 and the rack 222, the rotational motion of the gear 221 is converted into the linear motion of the door 21. The rack 222 is fixed at the contact point between the door 21 and the side wall 16 of the body 1. When the gear 221 rotates, it drives the rack 222 to move, which in turn drives the door 21 to move, thus opening or closing the door 21. The meshing transmission between the gear 221 and the rack 222 enables the smooth opening and closing of the door 21. At the same time, the large contact area between the rack 222 and the gear 221 effectively disperses pressure and extends service life.

[0042] Please continue reading. Figure 1 , Figure 2 and Figure 3 The limiting assembly includes sensors 26 located at preset limit positions on both sides of the door 21 in the direction of travel. The door panel assembly 2 also includes limiting posts 23, which are disposed on the side of the door 21 near the side wall 16 of the body 1, and are used to cooperate with the sensors 26 to output detection signals. Specifically, the sensors 26 in the limiting assembly cooperate with the limiting posts 23 of the door panel assembly 2 to achieve precise control of the movement of the door 21. The sensors 26 are disposed at the extreme positions on both sides of the door 21 in the direction of travel, and the limiting posts 23 are fixed on the side of the door 21 near the side wall 16 of the body 1. When the door 21 moves to the preset position, the limiting posts 23 touch the sensors 26 to generate a detection signal. In one embodiment, a micro switch or a photoelectric sensor 26 can be used as the detection element, and the limiting posts 23 can be made of rigid materials such as metal or plastic. In one embodiment, the sensors 26 can be mounted on the body frame. Through the coordinated action of sensor 26 and limit post 23, the movement status of door 21 can be monitored in real time and the opening and closing range of door 21 can be precisely controlled to prevent door 21 from sliding off the sliding track 161.

[0043] Please continue reading. Figure 1 , Figure 2 and Figure 3The limiting component also includes limiting protrusions 24, which protrude from the side wall 16 of the body 1. The limiting protrusions 24 are located on both sides of the sliding track 161 and are used to abut and limit the movement of the door 21. Specifically, the limiting protrusions 24 are protruding structures provided on the side wall 16 of the body 1, with their positions corresponding to both sides of the sliding track 161. This structure limits the range of movement of the door 21 through contact with it. It can be made of plastic or metal and fixed to the side wall 16 of the body 1 by injection molding or welding, or it can be integrally molded with the side wall 16 of the body 1. When the door 21 moves along the sliding track 161, the limiting protrusions 24 abut against the edge of the door 21, preventing the door 21 from exceeding the preset opening and closing range. In addition, the limiting protrusions 24 can also be provided with an elastic buffer layer to reduce the impact force when the door 21 moves. By setting limiting protrusions 24 on both sides of the sliding track 161, the door 21 can be effectively prevented from derailing or moving excessively during opening and closing, thus improving the stability of the door 21's movement. This structure, as a mechanical limiting device, forms a double protection with the electronic limiting system composed of sensor 26 and limiting post 23, preventing the door 21 from going out of control due to electronic component failure. The limiting protrusions 24 are symmetrically distributed on both sides of the sliding track 161, making the force on the door 21 more even on both sides, reducing the risk of the door 21's movement deviation. When the door 21 reaches the limiting position, the limiting protrusions 24 achieve precise positioning through physical contact. Combined with the independently moving door 21 design, this ensures the synchronicity of the door 21's opening and closing, and avoids structural damage caused by unilateral limiting failure, improving the overall reliability and service life of the mechanism.

[0044] Please continue reading. Figure 2 and Figure 3 The door panel assembly 2 includes a second rolling element 25, which is connected to the door 21 along one end of its rotation axis. The second rolling element 25 includes a curved surface that rolls in contact with the sliding track 161. Specifically, the door panel assembly 2 includes a second rolling element 25, which is connected to the door 21 via one end of its rotation axis, thereby driving the door 21 to move. Its surface is designed with a curved structure to maintain rolling contact with the sliding track 161. The second rolling element 25 achieves smooth movement of the door 21 through the cooperation of its curved surface with the sliding track 161. In a specific implementation, the second rolling element 25 is fixed to the door body by screws or clips. The contact surface between the curved surface of the second rolling element 25 and the sliding track 161 can be coated with a wear-resistant coating to improve its service life. Through the curved surface contact between the second rolling element 25 and the sliding track 161, the frictional resistance during door movement can be effectively reduced, making the door panel open and close more smoothly. In one embodiment, the second rolling element 25 is a bearing.

[0045] Please continue reading. Figure 2 and Figure 3The vehicle door 21 includes a first door 211 and a second door 212, which move in opposite directions to open or close the opening 12. Specifically, the vehicle door 21 consists of two independently moving first doors 211 and second doors 212, which move in opposite directions when opening or closing. Both the first doors 211 and second doors 212 are connected to the vehicle frame via bearings at the top, ensuring that the doors 21 can only move in a single direction. By setting up a structure with two doors 21 moving in opposite directions, the space occupied by the doors 21 when opening can be effectively reduced, improving the utilization rate of the vehicle's interior space. The independently moving door design gives the first doors 211 and second doors 212 their own degrees of freedom, avoiding the high installation precision requirements of traditional linkage structures and improving structural flexibility. The dual protection mechanism of electronic and mechanical limits ensures that the first doors 211 and second doors 212 can still stop safely in the event of electronic system failure, improving reliability. The movement of the door 21 is precisely controlled through the cooperation of the rack 222 and the motor, and the limit components ensure the stability of the door's opening and closing. In case of asynchrony, a reset operation can restore synchronization, reducing maintenance difficulty.
