Description

Technical Field

[0001] This utility model relates to the field of toy vehicle technology, and in particular to a novel self-unloading toy vehicle. Background Technology

[0002] Toy cars are a type of toy with high expandability. Among them, various types of simulated engineering vehicles offer high playability due to their diverse transmission structures. Simulated self-unloading toy cars, in particular, feature a cargo compartment that rotates from the rear to the rear of the toy car body. A drive mechanism lifts the compartment to automatically unload cargo. However, currently, only the cargo compartment of these simulated toy cars rotates up and down, which somewhat limits their playability. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of self-unloading toy vehicle, specifically a new type of self-unloading toy vehicle with a cover plate at the top of the vehicle body that can be opened or closed as the vehicle body rotates.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel self-unloading toy car, comprising a toy car body and a carriage component rotatably connected to the rear end of the toy car body, wherein a carriage cover is provided at the upper end of the carriage component, and a cover drive mechanism is provided on the carriage component and drivenly connected to the carriage cover, wherein the cover drive mechanism is used to drive the carriage cover to move up and down relative to the carriage component.

[0005] Specifically, the cover plate driving mechanism includes a drive shaft and drive rods connected to the drive shaft. There are two drive rods, which are respectively located on both sides of the carriage component and driven to both sides of the carriage cover plate. The drive shaft is rotatably connected to the bottom of the carriage component and connected to the drive rods at both ends.

[0006] Specifically, the cover plate driving mechanism also includes a limiting link, one end of which is rotatably connected to the carriage component and the other end is rotatably connected to the carriage cover plate.

[0007] Specifically, the toy car body is provided with a rotating drive rod. The lower end of the rotating drive rod is rotatably slidably connected to the toy car body, and the upper end of the rotating drive rod is fixedly connected to the drive shaft at the bottom of the carriage component. When the carriage component rotates upward around the rear end of the toy car body, it drags the rotating drive rod to rotate upward.

[0008] Specifically, the upper end of the rotating drive rod includes a fixed part and a clutch drive part. The fixed part is fixedly connected to the main body of the rotating drive rod, and the clutch drive part is connected to the fixed part by tooth meshing. The fixed part is rotatably connected to the drive shaft, and the clutch drive part is fixedly connected to the drive shaft.

[0009] Specifically, the toy car body is equipped with a carriage lifting drive mechanism, which includes a telescopic drive mechanism and a telescopic push rod. The telescopic drive mechanism is driven to the telescopic push rod, and the telescopic push rod is driven to the bottom of the carriage component.

[0010] Specifically, the telescopic push rod is driven to the carriage components via a drive shaft, and the drive end of the telescopic push rod is rotatably connected to the drive shaft at the bottom of the carriage components.

[0011] Specifically, the telescopic drive mechanism includes a drive motor, a reduction gear set, and a drive gear. The drive motor is connected to the drive gear through the reduction gear set. The drive gear is a large-diameter gear. An eccentric drive block is provided on the side of the drive gear and is rotatably connected to the telescopic push rod. When the drive gear rotates, it pushes the telescopic push rod up and down through the eccentric drive block.

[0012] The beneficial effects of this utility model are as follows: a cover plate is provided on the carriage component of the self-unloading toy car, and the cover plate is driven up and down by a cover plate driving mechanism. The cover plate driving mechanism is driven by a rotating drive rod provided on the main body of the toy car. The rotating drive rod rotates with the carriage component around the rear end of the toy car body, thereby realizing the synchronous movement of the cover plate and the carriage component, and improving the playability of the self-unloading toy car.

[0018] Example 1, referring to Figure 1-5 A novel self-unloading toy vehicle includes a toy vehicle body 1 and a carriage component 2 rotatably connected to the rear end of the toy vehicle body 1. A carriage cover 3 is provided on the upper end of the carriage component 2. A cover drive mechanism 4 is provided on the carriage component 2 and is droopingly connected to the carriage cover 3. The cover drive mechanism 4 is used to drive the carriage cover 3 to move up and down relative to the carriage component 2.

[0019] In this embodiment, the carriage component 2 can rotate around the rear end of the toy car body 1 to perform unloading operations. When the carriage component 2 rotates upward to unload, the cover plate drive mechanism 4 can drive the carriage cover plate 3 at the upper end of the carriage component 2, causing it to open from the top of the carriage component 2. By adding the carriage cover plate 3 and the cover plate drive mechanism 4, the playability of the self-unloading toy car can be effectively increased, improving its playability. The cover plate drive mechanism 4 includes a drive shaft 41 and drive rods 42 connected to the drive shaft 41. Two drive rods 42 are located on both sides of the carriage component 2 and are driven and connected to both sides of the carriage cover plate 3. The drive shaft 41 is rotatably connected to the bottom of the carriage component 2 and connected to the drive rods 42 at both ends. By rotating the drive shaft 41, the drive rods 42 on both sides of the carriage component 2 can be rotated, causing the carriage cover plate 3 to open upward under the drive of the drive rods 42. Meanwhile, in order to ensure that the carriage cover 3 remains parallel to the top surface of the carriage component 2 when it is opened upwards, the cover drive mechanism 4 also includes a limiting link 43. One end of the limiting link 43 is rotatably connected to the carriage component 2, and the other end is rotatably connected to the carriage cover 3. When the drive rod 42 drives the carriage cover 3 to open upwards, the carriage cover 3 simultaneously pulls the limiting link 43 to rotate, thereby keeping the carriage cover 3 parallel to the upper surface of the carriage component 2.

[0020] In this embodiment, the cover plate driving mechanism 4 is driven by the rotation of the carriage component 2. Specifically, a rotating drive rod 5 is provided on the toy car body 1. The lower end of the rotating drive rod 5 is rotatably slidably connected to the toy car body 1, and the upper end of the rotating drive rod 5 is fixedly connected to the drive shaft 41 at the bottom of the carriage component 2. When the carriage component 2 rotates upward around the rear end of the toy car body 1, it drags the rotating drive rod 5 to rotate upward. When the carriage component 2 rotates upward, it drags the lower end of the rotating drive rod 5 to move backward along the toy car body 1, and at the same time, it causes the upper end of the rotating drive rod 5 to move upward. At this time, the upper end of the rotating drive rod 5 rotates around the axis of the drive shaft 41 at the bottom of the carriage component 2. Since the upper end of the rotating drive rod 5 is fixedly connected to the drive shaft 41, the rotation of the upper end of the rotating drive rod 5 drives the drive shaft 41 to rotate, thereby driving the drive rod 42 of the cover plate driving mechanism 4 to rotate, causing the carriage cover 3 to move upward. Similarly, when the carriage component 2 rotates downward to reset, the carriage cover 3 resets along the original path. The upper end of the rotating drive rod 5 includes a fixed part 51 and a clutch drive part 52. The fixed part 51 is fixedly connected to the main body of the rotating drive rod 5, and the clutch drive part 52 is connected to the fixed part 51 by tooth meshing. The fixed part 51 is rotatably connected to the drive shaft 41, and the clutch drive part 52 is fixedly connected to the drive shaft 41. When the rotating drive rod 5 rotates and drives the carriage cover 3 through the cover drive mechanism 4, if the carriage cover 3 cannot move upward due to external force (such as the carriage cover 3 being pressed down hard during play), the cover drive mechanism 4 will apply a large pressure to the rotating drive rod 5, which will cause damage to the related connecting structures. Through the disengageable connection between the fixed part 51 and the clutch drive part 52 at the upper end of the rotating drive rod 5, the fixed part 51 and the clutch drive part 52 will separate when the carriage cover 3 is subjected to a certain force, thereby avoiding damage to the cover drive mechanism 4, the rotating drive rod 5, and their related connecting structures.

[0021] The self-unloading toy car of this application can be driven to rotate the carriage component 2 using an electric control device. Therefore, in a further embodiment, the toy car body 1 is provided with a carriage lifting drive mechanism 6. The carriage lifting drive mechanism 6 includes a telescopic drive mechanism 61 and a telescopic push rod 62. The telescopic drive mechanism 61 is driven to drive the telescopic push rod 62, and the telescopic push rod 62 is driven to drive the bottom of the carriage component 2. The telescopic push rod 62 can be driven to drive the carriage component 2 via a drive shaft 41, and the drive end of the telescopic push rod 62 is rotatably connected to the drive shaft 41 at the bottom of the carriage component 2. Specifically, the telescopic drive mechanism 61 includes a drive motor 611, a reduction gear set 612, and a drive gear 613. The drive motor 61 is driven by the drive gear 613 via the reduction gear set 612. The drive gear 613 is a large-diameter gear, ensuring that the telescopic push rod 62 has sufficient movement distance to push the carriage component 2 up. An eccentric drive block 614 is rotatably connected to the telescopic push rod 62 on the side of the drive gear 613. When the drive gear 613 rotates, it pushes the telescopic push rod 62 up and down through the eccentric drive block 614. By using the telescopic drive mechanism 61 to drive the telescopic push rod 62 up and down, the carriage component 2 can be driven to rotate, enabling it to unload and reset. Furthermore, only one electric drive mechanism is needed to simultaneously drive the movements of both the carriage component 2 and the carriage cover 3. Meanwhile, to enhance the similarity between the dump truck toy and the real dump truck, a first simulated push rod component 7 is provided between the front end of the truck body component 2 and the toy truck body 1. The first simulated push rod component 7 consists of a first fixed part 71 and a first telescopic part 72 slidably connected to the first fixed part 71. When the truck body component 2 rotates upward, the first simulated push rod component 7 is stretched, and the first telescopic part 72 is pulled out from the first fixed part 71, achieving the effect of simulating the hydraulic push rod of a real dump truck. Similarly, a second simulated push rod component 8 is also provided on the truck body component 2 and connected to the drive rod 42 of the cover plate drive mechanism 4. Likewise, the second simulated push rod component 8 consists of a second fixed part 81 and a second telescopic part 82 slidably connected to the second fixed part 81. When the truck body cover 3 moves upward, the second simulated push rod component 8 is stretched, and the second telescopic part 82 is pulled out from the second fixed part 81 as the drive rod 42 rotates.

[0022] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
