Technical Field

[0001] This utility model relates to toy cars, and more particularly to an automatic material unloading mechanism for children's engineering vehicles, and also to a children's engineering vehicle having the automatic material unloading mechanism. Background Technology

[0002] Children's engineering vehicles are toy vehicles designed specifically for children, aiming to help children learn and explore engineering knowledge while playing by simulating the functions and operation of real engineering vehicles.

[0003] Currently, there are many types of children's construction vehicles with cargo beds on the market. However, the cargo bed is mostly connected to the vehicle body as one piece, and the cargo bed cannot be flipped over to empty materials. Some children's construction vehicles have a cargo bed that is rotatably connected to the vehicle body, and the cargo bed can be flipped over to empty materials through manual operation. Overall, the structure is relatively simple and the operability is low.

[0004] A few children's engineering vehicles have a cargo bed that can be tipped over and unloaded by installing an electric push rod between the cargo bed and the vehicle body. This solution solves the problem of automatic unloading of materials in children's engineering vehicles. At the same time, this utility model provides a new technical solution to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic unloading mechanism for children's engineering vehicles. The unloading mechanism uses a motor to drive a gear and rack transmission. The upper end of the arc-shaped rack is fixedly installed with a truck bed. The arc-shaped rack provides support and rotation for the truck bed. The truck bed is turned over by a trigger connected to the base and the side linkage plate of the arc-shaped rack in rolling contact. The mechanism has a compact structure, high operability and strong stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic unloading mechanism for a children's engineering vehicle includes a bucket, an arc-shaped rack, a base, a bracket, and a drive unit. The bucket is rotatably connected to the vehicle body via a rotating shaft.

[0008] The base and bracket are fixedly installed on the vehicle body, the drive device is fixedly installed on the bracket, and a gear is connected to the drive shaft of the drive device;

[0009] The upper end of the arc-shaped rack is fixedly connected to the truck bed. The arc-shaped rack is arc-shaped and its center is located on the axis of the rotating shaft. The arc-shaped rack passes through the base and meshes with the gear for transmission.

[0010] The upper end of the arc-shaped rack is integrally connected to the connecting block, and the lower part of the truck bed is fixedly connected to the connecting block and placed above the base.

[0011] A limiting groove is provided below the truck bed, and the connecting block is fixedly connected to the limiting groove.

[0012] A trigger is connected below the base, and a linkage plate is fixedly installed on the side of the arc-shaped rack. The linkage plate has a groove, which is set along the arc direction. The two ends of the groove have a first limit position and a second limit position, respectively. The first limit position and the second limit position of the groove can trigger the trigger.

[0013] The trigger is equipped with a button and a spring. The spring is placed outside the button, and a roller is installed at the end of the spring. The roller makes rolling contact with the groove.

[0014] The upper end of the groove is the first extreme position, and the lower end of the groove is the second extreme position; the first extreme position is the un-tilted state of the truck bed, and the second extreme position is the tilted state of the truck bed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses an automatic material unloading mechanism for children's construction vehicles, which is generally used in conjunction with children's construction vehicles, such as... Figures 1 to 7 As shown, it mainly includes a truck bed 1, an arc-shaped rack 2, a base 3, a bracket 4, and a drive device 5. The truck bed 1 is rotatably connected to the vehicle body via a rotating shaft 12.

[0029] The base 3 and the bracket 4 are fixedly installed on the vehicle body, and the drive device 5 is fixedly installed on the bracket 4. The gear 51 is installed on the drive shaft 52 of the drive device 5. The drive device 5 is a motor driver. When working, the drive shaft 52 can rotate and drive the gear 51 to rotate synchronously.

[0030] The arc-shaped rack 2 passes through the base 3 and meshes with the gear 51. The upper end of the arc-shaped rack 2 is fixedly connected to the truck bed 1, which supports and rotates the truck bed 1.

[0031] The center of the arc-shaped rack 2 is located on the axis of the rotating shaft 12. Under the transmission action of the gear 51 and the arc-shaped rack 2, the hopper 1 can automatically flip and unload materials around the rotating shaft 12. The center of the arc-shaped rack 2 and the axis of the rotating shaft 12 are concentrically arranged, so that both can remain stable during the movement. When the drive shaft 52 is working, it maintains a constant rotation speed, which can drive the arc-shaped rack 2 to deflect, thereby driving the hopper 1 to flip at a constant speed, which can always keep the flipping speed of the hopper 1 consistent, thus forming a uniform flipping action.

[0032] like Figure 4 As shown, a connecting block 21 is integrally connected to the upper end of the arc-shaped rack 2, and a limiting groove 11 matching the connecting block is opened below the truck bed 1. The connecting block 21 is installed in the limiting groove 11 and locked with screws to achieve a fixed connection between the truck bed 1 and the arc-shaped rack 2.

[0033] like Figure 7 As shown, a groove 221 is provided on the linkage plate 22 on the side of the arc rack 2. The groove 221 is set along the arc direction of the arc rack 2. A first limit position and a second limit position are respectively provided at both ends of the groove 221. An inclined abutment surface 222 is provided at both the first limit position and the second limit position, which is mainly used to abut against the roller 323.

[0034] like Figure 3 , Figure 4 and Figure 7 As shown, a trigger 32 is connected below the base 3, and a button 321 and a spring 322 are installed on the side of the trigger 32. The trigger 32 can be triggered by pressing the button. The spring 322 is placed outside the button 321. The first end of the spring 322 is connected to the trigger 32, and the second end is equipped with a roller 323. The middle section of the spring 322 near the first end presses against the button 321. By pressing the roller 323 at the second end, the spring 322 can be elastically deflected, thereby pressing the button 321.

[0035] The roller 323 at the second end of the spring 322 rolls into contact with the groove 221 and can roll and slide within the groove 221. When the roller 323 contacts the groove 221 at the first and second limit positions, the roller 323 is subjected to pressure from the inclined pressing surface 222, which can press the spring 322 and trigger the trigger 32.

[0036] When the truck bed 1 needs to be tilted, the drive device 5 starts to work. The drive shaft 52 drives the gear 51 to rotate. The gear 51 meshes with the arc rack 2 to drive the arc rack 2 to produce lifting and lowering movements, and at the same time, it drives the truck bed 1 above the arc rack 2 to tilt.

[0037] As the arc-shaped rack 2 moves up and down, the first or second limit position corresponding to the arc-shaped rack 2 will approach the trigger 32 until the trigger 32 is triggered. After the trigger 32 is pressed and triggered, it will control the drive device 5 to stop working, and the truck bed 1 will be maintained at the corresponding height position and in the corresponding state. Then, when the drive device 5 works again, the drive shaft 52 will rotate in the opposite direction, driving the gear 51 to reverse, repeating the above control action, which can flip the truck bed 1 to another state, thereby realizing the flipping control of the truck bed 1.

[0038] This embodiment also discloses a children's engineering vehicle, including the automatic material unloading mechanism for children's engineering vehicles as described above, specifically referring to... Figure 1 , Figure 2 As shown.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
