Description

Technical Field

[0001] The present application relates to the technical field of flywheel starting, and in particular to a low-power-consumption flywheel starting device. Background Art

[0002] Flywheels are parts of many mechanical devices and are mainly used to recover kinetic energy. The main way this is done is that the excess energy of the mechanical equipment is input into the flywheel. The inertia of the flywheel's own rotation will keep the flywheel rotating, thereby achieving a better effect of recovering kinetic energy.

[0003] However, the traditional technology is to directly drive the flywheel to rotate through a motor, and the size difference between the motor's output shaft and the flywheel is very large. Therefore, when the motor drives the flywheel to start, the ratio of the resistance arm to the power arm will be too large, resulting in a slow start-up speed of the flywheel driven by the motor, and the motor driving the flywheel to start will consume more time and energy.

The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] Further, the stator assembly is used to form a first embedding area, and the rotor assembly is inserted into the first embedding area, so that the stator assembly and the rotor assembly form a combination state of an outer stator and an inner rotor.

[0007] Further, the rotor assembly is used to form a second embedding area, and the stator assembly is inserted into the second embedding area so that the stator assembly and the rotor assembly form a combined state of an outer rotor and an inner stator.

[0008] Furthermore, the stator components are arranged in two groups, and the rotor components are used to form a third embedded area; one group of the stator components is inserted into the third embedded area; the other group of the stator components forms a fourth embedded area; the rotor components are inserted into the fourth embedded area.

[0009] Furthermore, the rotor assemblies are provided in two groups, and both groups of the rotor assemblies are mounted on the flywheel; the sizes of the two groups of the rotor assemblies are different so that a fifth embedded area is formed between the two groups of the rotor assemblies; and the stator assembly is inserted into the fifth embedded area.

[0010] Furthermore, a mounting ring plate having a mounting surface is disposed on the side of the flywheel edge; the mounting surface is perpendicular to the side of the flywheel edge; and the rotor assembly is disposed on the mounting surface.

[0011] Furthermore, the rotor assembly includes: a rotor frame and a coil; a plurality of accommodating slots for placing the coil are formed on the rotor frame; a plurality of the coils are provided, and the plurality of the coils are electrically connected in sequence.

[0012] Furthermore, the starting device also includes: an outer shell cover, which is used to accommodate the rotor assembly and the stator assembly; a rotating shaft is provided on the flywheel, and the rotating shaft is rotatably connected to the outer shell cover; the stator assembly is fixed to the inner wall surface of the outer shell cover; and a heat dissipation groove is provided on the outer shell cover.

[0029] A low-power flywheel 3 starting device comprises: a stator assembly 1 and a rotor assembly 2; the rotor assembly 2 is installed at the edge of the flywheel 3. The stator assembly 1 cooperates with the rotor assembly 2; the rotor assembly 2 drives the flywheel 3 to rotate when the stator assembly 1 is powered; the edge of the flywheel 3 is away from the middle of the flywheel 3. In this embodiment, the stator assembly 1 and the rotor assembly 2 are both prior arts, and the stator assembly 1 cooperates with the rotor assembly 2, so the stator assembly 1 can rotate the rotor assembly 2 when it is powered.

[0030] By adopting the above technical solution, the rotor assembly 2 is directly connected to the edge of the flywheel 3, so the torque transmission between the rotor assembly 2 and the flywheel 3 is close to the length of the resistance arm and the power arm, so that the stator assembly 1 makes it easier for the rotor assembly 2 to drive the flywheel 3 to rotate. Compared with the traditional technology, since the traditional technology directly drives the flywheel 3 to rotate through a motor, and the size difference between the output shaft of the motor and the flywheel 3 is very large, when the motor drives the flywheel 3 to start, the ratio of the resistance arm to the power arm is too large, resulting in a slower speed of the motor driving the flywheel 3 to start, and the motor driving the flywheel 3 to start will consume more time and energy. However, the present application directly installs the rotor assembly 2 on the edge of the flywheel 3, which greatly reduces the ratio of the resistance arm to the power arm of the rotor assembly 2, making the flywheel 3 start faster.

[0031] In some specific schemes, the stator assembly 1 is used to form a first embedded area, which is a cavity in the middle of the stator assembly 1. The rotor assembly 2 is inserted into the first embedded area so that the stator assembly 1 and the rotor assembly 2 form a combination state of an outer stator and an inner rotor.

[0032] In some specific schemes, the rotor assembly 2 is used to form a second embedded area, which is a cavity in the middle of the rotor assembly 2. The stator assembly 1 is inserted into the second embedded area so that the stator assembly 1 and the rotor assembly 2 form a combined state of an outer rotor and an inner stator.

[0033] In some specific schemes, the stator assembly 1 is provided in two groups, and the rotor assembly 2 is used to form a third embedded area; one group of the stator assemblies 1 is inserted into the third embedded area; the other group of the stator assemblies 1 forms a fourth embedded area; the rotor assembly 2 is inserted into the fourth embedded area.

[0034] In some specific schemes, the rotor assembly 2 is provided in two groups, and the two groups of the rotor assembly 2 are both installed on the flywheel 3; the sizes of the two groups of the rotor assembly 2 are different so that a fifth embedded area is formed between the two groups of the rotor assembly 2; the stator assembly 1 is inserted into the fifth embedded area.

[0035] In some specific schemes, a mounting ring plate having a mounting surface is provided on the side of the edge of the flywheel 3; the mounting surface is perpendicular to the side of the edge of the flywheel 3; and the rotor assembly 2 is provided on the mounting surface.

[0036] Specifically, the rotor assembly 2 includes: a rotor frame and a coil; a plurality of accommodating slots for accommodating the coil are formed on the rotor frame; a plurality of the coils are provided, and the plurality of the coils are electrically connected in sequence.

[0037] Specifically, the starting device also includes: an outer shell cover, which is used to accommodate the rotor assembly 2 and the stator assembly 1; a rotating shaft is provided on the flywheel 3, and the rotating shaft is rotatably connected to the outer shell cover; the stator assembly 1 is fixed to the inner wall surface of the outer shell cover; and a heat dissipation groove is provided on the outer shell cover.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
