Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a high-torque unloading and lifting structure of a toy engineering vehicle. Background Art

[0002] Toy engineering vehicles are highly playable. By simulating the structure of real engineering vehicles, more actions can be performed during play. In order to further improve the playability of toy engineering vehicles, it is necessary to increase the output torque of the toy vehicles, especially for engineering vehicles with a discharge hopper that can perform discharge actions. The torque required during the discharge process is greater. The current structure uses an electric push rod to simulate the hydraulic push rod in a real engineering vehicle to drive the discharge hopper. However, electric push rods have the disadvantages of complex transmission structure, high processing difficulty, and easy damage. Utility Model Content

[0012] Example 1, reference Figure 1-3 A high-torque unloading and lifting structure for a toy engineering vehicle comprises a driving motor 1, a reducer 2, an output transmission shaft 3 and a driving gear 4. The driving motor 1 is drivingly connected to the output transmission shaft 3 through the reducer 2. The end of the output transmission shaft 3 is provided with a helical tooth 31 drivingly connected to the driving gear 4. The driving gear 4 is a half gear. The toothed side of the driving gear 4 is meshed with the output transmission shaft 3, and the untoothed side of the driving gear 4 is fixedly connected to the unloading hopper 5 of the toy engineering vehicle. The driving gear 4 and the unloading hopper 5 are both rotationally connected to the toy engineering vehicle through a rotating shaft 51.

[0013] In this embodiment, the drive motor 1 and the reducer 2 are fixedly arranged on the body of the toy engineering vehicle. The toy engineering vehicle is also provided with a battery and a control circuit board for powering and controlling the drive motor 1. After the drive motor 1 is decelerated by the reducer 2, its torque can be increased by reducing the speed. After the drive motor 1 passes through the reducer 2, it drives the output transmission shaft 3 to rotate. The helical teeth 31 at the end of the output transmission shaft 3 mesh with the drive gear 4 to drive the drive gear 4 to rotate. The drive gear 4 adopts a half gear, so that the side of the drive gear 4 without teeth can be fixedly connected with the discharge hopper 5. The rotation of the drive gear 4 will drive the discharge hopper 5 to rotate around the rotating shaft 51, thereby realizing the discharge lifting action of the discharge hopper 5, and the reverse rotation of the drive motor 1 can drive the discharge hopper 5 to descend and reset. The overall structure of the discharge lifting drive structure of this embodiment is simpler, easy to process and assemble, and can provide a stable and large torque for the discharge hopper 5, thereby improving the playability of the toy engineering vehicle. Specifically, the drive gear 4 and the discharge hopper 5 are fixedly connected by a mounting bracket 52.

[0014] Specifically, the discharge lifting structure of this embodiment further includes an auxiliary limiting rod 6, which is divided into two and is disposed on both sides of the discharge hopper 5 of the toy engineering vehicle, one end of the auxiliary limiting rod 6 is rotatably connected to the body of the toy engineering vehicle, and the other end is rotatably connected to the discharge hopper 5; the auxiliary limiting rod 6 includes a fixed sleeve 61 and a sliding connecting rod 62, and the sliding connecting rod 62 is slidably disposed in the fixed sleeve 61. The two ends of the auxiliary limiting rod 6 are respectively connected to the body of the toy engineering vehicle and the discharge hopper 5, which can limit the rotation trajectory of the discharge hopper 5, and prevent the discharge hopper 5 from being displaced in the left and right directions during the rotation process, which affects the rotation action of the discharge hopper 5.

[0015] Specifically, a telescopic protective cover 7 is provided on the outside of the driving gear 4, one end of the telescopic protective cover 7 is fixed to the body of the toy engineering vehicle, and the other end is fixed to the discharge hopper 5. The telescopic protective cover 7 can wrap and protect the outside of the driving gear 4 to prevent foreign objects from getting stuck on the driving gear 4, and also prevent the fingers of the operator from being pinched during the rotation of the driving gear 4. The telescopic protective cover 7 can be made of rubber material.

[0016] Of course, the above are only preferred implementations of the present utility model, and are not intended to limit the scope of use of the present utility model.
