detailed description

All of the features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner other than mutually exclusive features and/or steps.

Any feature disclosed in the specification, including any additional claims, abstract and drawings, may be replaced by other equivalents or alternative features, unless otherwise stated. That is, unless specifically stated, each feature is only one example of a series of equivalent or similar features.

As shown in FIG. 1 to FIG. 7, an automatic balancing system for an electric twisting vehicle of the present invention comprises a supporting frame 5 in the middle of an automatic balancing system of an electric twisting vehicle, and the supporting frame 5 is composed of two aluminum castings 1 Composition, the middle of two aluminum castings 1 is connected by a main shaft 2, which is a cylindrical hollow tube;

Two sleeves 3 are provided on the outside of the main shaft, and the sleeve 3 has a hollow cylindrical shape whose inner diameter is larger than the outer diameter of the main shaft.

Example 1

As shown in FIG. 2 and FIG. 4, an aluminum block 6 is fixedly mounted on both ends of the main shaft of the support frame 5, and two first screws 7 are disposed on the lower end support frame of the aluminum block, and the first screw 7 passes through the support frame 5 and The aluminum block 6 at the upper end of the support frame is fixedly connected, and the lower end surface of the aluminum block 6 is provided with a corresponding first screw hole at the position of the first screw 7, and a metal elastic member 8 is mounted on the upper end surface of the aluminum block.

The metal elastic member 8 is a flat plate. The length of the metal elastic member 8 is greater than the length of the rotating shaft. The two ends of the metal elastic member respectively protrude from the two ends of the rotating shaft, and the two outer ends of the metal elastic member are provided with two second screws. a second screw 9 is mounted through each of the second screw holes, and a corresponding third screw hole is disposed on the upper end surface of the aluminum block 5 of the second screw 9, and the metal elastic member 8 passes through the second screw 9 It is fixedly connected to the aluminum block 5.

The metal elastic member 8 is a manganese steel sheet; the first screw 7 is located at the outer end of the two second screws 9, and the upper end surface of the aluminum block is provided with a mating surface, and both ends of the metal elastic member are disposed in the mating surface The third screw hole is disposed on the bottom surface of the mating surface of the upper end of the aluminum block; the aluminum block 5 is provided with two through holes 10, the through hole is located opposite to each of the first screws, and the upper end of the first screw is disposed on the bottom Inside the through hole.

In this embodiment, the shaft hole in the middle of the rotating shaft has a circular shape, and the metal elastic member is exemplified in a planar shape. Therefore, at the time of installation, the bottom of the metal elastic member cannot closely fit the bottom surface of the shaft hole, and the metal elastic member is closely attached. The bottom will form a certain gap with the bottom surface of the shaft hole. Therefore, although this method can achieve the function of the metal elastic member, it is not recommended in practical use. The selection of the metal elastic member should be selected according to the shape of the shaft hole, if the shaft hole If the shape is square, it is suitable to use a flat metal elastic member, so that the bottom surface of the metal elastic member is attached to the axial hole surface to obtain an optimal installation method. In addition, in the embodiment, the aluminum block is selected for fixing, and the fixing manner is one of them. The metal elastic member must be fixed to be able to rebound in real time. Therefore, the fixing method exemplified in the present invention is not the only one.

Embodiment 2

As shown in Fig. 1 and Fig. 6, in the figure, the axial hole in the middle of the rotating shaft is a circular hole, so the metal elastic member is designed into an arc shape, and the curvature must be the same as the arc of the shaft hole, so that the curved metal elastic member It can be attached to the bottom surface of the shaft hole of the rotating shaft during installation, which can obtain the most suitable installation method, save space, and reserve enough space for the later embedding and other operations. In this embodiment, the arc-shaped metal elasticity is selected. For example, a shaft hole having a circular shape is used as an example. In this embodiment, a metal elastic piece is selected as the metal elastic member.

In FIG. 1 and FIG. 6, four positioning posts 11 are disposed on the upper end surface of the support frame, and two positioning posts 11 are respectively disposed at two ends of the main shaft 2, and an arc-shaped metal elastic member 12 is disposed through the main shaft, and the curved metal elastic body is provided. The piece 12 is fixed on the four positioning posts 11 by screws, so that the curved metal elastic member fits tightly on the inner wall of the rotating shaft, thereby completing the automatic balance reset, without using the body to balance, in the figure, the selection and positioning of the curved metal elastic parts The fixing of the column is completed in a fixed manner. In actual production, any manner of fixing the metal elastic member may be selected, such as the aluminum block fixing method in the first embodiment, the connection manner between the positioning post and the screw, etc., in this embodiment. In the actual production process, any method for fixing and locking the metal elastic member in the actual production process falls within the technical field protected by the present invention.

Since the metal elastic member is added, the metal elastic member is bent, but since the metal elastic member has a repulsive force after being twisted, when the entire vehicle body is in an unbalanced state, the balance can be automatically restored by the rebound force, and it is no longer necessary to control the balance by the human body, and it is easier to get started. .

The invention has the beneficial effects that the inventive invention adds the metal elastic member to the field of the automatic balance system of the electric twisting vehicle, and the rebound of the elastic deformation of the metal elastic member is compared with other products which cannot automatically restore the balance. The force realizes the reset of the automatic balance system of the electric twisting car, and the body is automatically restored to a horizontal state in a more convenient and safe manner, which is especially suitable for beginners to use, the operation is simpler, the operation is easier, the structure is simple, and the cost is reduced. The design is novel and more suitable for promotion and use. .

The above is only the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of by the creative work are included in the scope of the present invention. Therefore, the scope of the invention should be determined by the scope of the invention as defined by the appended claims.
