DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example 1

[0034] like Figure 1-Figure 9 As shown: a new type of remote-controlled excavator toy, including a frame 1 and a crawler base 2. The frame 1 with an excavating boom 3 and a cab 4 is installed on the crawler base 2. In addition to being able to move straight on the ground through the crawler base 2, the frame 1 can also rotate relative to the crawler base 2 to adjust its own excavation direction.

[0035] Furthermore, the rotation function of the frame 1 is realized by the frame drive unit 10 provided in the frame 1. The frame drive unit 10 is a drive box structure, which is equipped with a frame motor 101 and a plurality of meshing transmission frame gears 102. A ring gear plate 20 is inserted in the position of the track base 2 for rotational combination with the frame bottom plate 11. One of the plurality of frame gears 102 for external output is located in the ring gear plate 20 and is driven to cooperate with it. Under the transmission cooperation between the frame gear 102 and the ring gear plate 20, the frame 1 can rotate relative to the track base 2. Of course, there are two buffer teeth 1021 formed with similar end teeth among the plurality of frame gears 102. With the help of the buffer teeth 1021 and the spring, the buffer teeth 1021 can produce an indirect transmission mode similar to a clutch. Compared with direct transmission, the rotation stability of the frame 1 can be improved to prevent some accessories from being directly impacted.

[0036] Furthermore, the excavation boom 3 comprises a main arm 30, a secondary arm 31 and a bucket 32 ​​which are hinged to each other, and the excavation boom 3 is swingably arranged on the vehicle frame 1 through the main arm 30, and the main arm 30 is supported by telescopic rods 33 arranged on both sides of the vehicle frame 1. Figure 2 , Figure 3 As shown, the frame 1 has a telescopic rod drive box including a telescopic rod motor 341 and a plurality of telescopic rod gears 342 as a boom drive unit 34. The telescopic rod drive box can drive the telescopic rod 33 to actively extend and retract, thereby causing the excavating boom 3 supported by it to swing up and down accordingly.

[0037] Specifically, the box body of the telescopic rod driving box is obliquely fixed in the frame 1, and its several telescopic rod gears 342 are driven to rotate by the telescopic rod motor 341, and the telescopic rods 33 located on both sides are respectively combined with a telescopic rod gear 342, so that they can be actively extended and retracted under the drive of the telescopic rod gear 342.

[0038] Specifically, the telescopic rod 33 includes an outer rod 331 and an inner rod 332 that are movably sleeved, wherein the outer rod 331 is hinged to the main arm 30 of the excavating boom 3 through a hinge joint formed at its end, and the inner rod 332 is combined with the telescopic rod gear 342 of the telescopic rod driving box. The outer rod 331 and the inner rod 332 are both hollow rods, an inner screw 3311 is inserted into the outer rod 331, and the inner rod 332 is threadedly connected to the inner screw 3311 through its own internal threads. When the inner rod 332 is driven to rotate by the telescopic rod gear 342, the outer rod 331 will extend or retract relative to the inner rod 332 due to the thread action, thereby controlling the up and down swing of the excavating boom 3.

[0039] Specifically, since the swing of the excavating boom 3 will cause the telescopic rod 33 to swing accordingly, but the telescopic rod drive box itself is fixedly arranged, in order to avoid interference with each other, in this embodiment, the inner rod 332 of the telescopic rod 33 is divided into a long rod portion 3321 and a short rod portion 3322, the long rod portion 3321 is used to be combined with the outer rod 331, and the short rod portion 3322 is used to be combined with the telescopic rod gear 342, and the long rod portion 3321 and the short rod portion 3322 are connected to each other via a universal joint 3323, and the universal joint 3323 can give the long rod portion 3321 the ability to move arbitrarily to avoid the above-mentioned interference.

[0040] Specifically, the telescopic rod gear 342 directly combined with the telescopic rod 33 is a cap-type structure with a protrusion, and the short rod portion 3322 of the inner rod 332 is movably plugged into the protrusion of the telescopic rod gear 342, and is fixed to each other by a lateral latch 3421; the reason for adopting the above-mentioned design is that if the short rod portion 3322 is directly and tightly plugged into the telescopic rod gear 342, the connection between the two will easily wear each other after a period of time. Since the force on the connection is relatively large when the telescopic rod 33 is extended or retracted, the wear and tear is very likely to cause the telescopic rod 33 and the telescopic rod gear 342 to separate from each other or even break, causing the structure to be damaged and unable to continue to be used. The use of a latch-type fixed connection can avoid the occurrence of this problem to a certain extent, thereby improving the service life of the toy.

[0041] Specifically, the frame 1 has a frame body 12, and the excavating boom 3 is hinged on the frame body 12. At the same time, the frame body 12 is also formed with an opening, and the telescopic rod 33 passes through the opening and is combined with the telescopic rod driving box.

[0042] Furthermore, the main arm 30 and the auxiliary arm 31 of the excavating boom 3 are respectively swingably equipped with an electric push rod 35, which is used to push the auxiliary arm 31 and the bucket 32 ​​to adjust the structural angle. The push rod 35 used to push the bucket 32 ​​is respectively hinged to the hinge piece 351 and the hinge rod 352 at the telescopic end, the hinge piece 351 is used to be hingedly combined with the bucket 32, and the hinge rod 352 is used to be hingedly combined with the auxiliary arm 31.

[0043] Specifically, the structure of the push rod 35 is similar to the telescopic rod 33, that is, a threaded design is adopted to realize the telescopic push-pull action; Figure 8 As shown, the inner rod 332 is used to realize the telescopic function, and the inner screw 3311 is fixedly plugged with the protrusion of the telescopic rod gear 342 of the hat-type structure through the latch 3421.

[0044] Specifically, in order to prevent the main arm 30, the auxiliary arm 31, and the bucket 32 ​​from excessively rotating during the driving process, causing the excavation boom 3 to be worn. Figure 7As shown, a limit switch 36 is also installed inside the main arm 30 and the auxiliary arm 31. If the main arm 30, the auxiliary arm 31 and the bucket 32 ​​contact the corresponding limit switch 36 after rotation, the limit switch 36 will stop the drive of the corresponding structure, so that the main arm 30, the auxiliary arm 31 and the bucket 32 ​​are correspondingly in a stationary state.

[0045] Further, such as Figure 5 As shown, the left and right sides of the track base 2 are track parts 21, and the track part 21 is composed of a track 211 wrapped around the periphery of a track wheel 212 and a transmission wheel 213. The track part 21 drives the transmission wheel 213 to rotate through its own track motor, so that the track 211 can move accordingly to drive the frame 1 forward or backward.

[0046] Example 2

[0047] like Fig.10 , Fig.11 As shown: the boom drive unit 34 is a boom drive box with a boom motor 343, an incomplete gear 301 is installed at the end of the main arm 30 of the excavating boom 3 articulated with the vehicle frame 1, and the motor screw provided at the output end of the boom motor 3 cooperates with the incomplete gear 301 in transmission, thereby giving the excavating boom 3 the ability to actively swing. When the excavating boom 3 swings, the telescopic rod 33 articulated with the vehicle frame seat 12 can be driven to extend and retract accordingly. Of course, since the telescopic rod 33 of this embodiment is driven to extend and retract, it is not necessary to use the threaded telescopic rod of embodiment 1, and only an ordinary telescopic rod can be used, which can reduce the structural cost of the excavating boom 3 to a certain extent.

[0048] The usage of this design is similar to that of traditional remote control toys. It mainly controls the operation of each motor in the excavator through the remote control, so that the excavator can move, rotate, dig and perform other actions accordingly.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
