Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0044] Embodiment One

[0045] In combination Figures 1 to 5 As shown in the drawings, the embodiment of the present application provides a hybrid motor 100, comprising a housing 10 in a cylindrical shape and having a receiving space 104, a first motor unit 20 fixed in the housing 10, and a second motor unit 30 fixed in the first motor unit 20, the first motor unit 20 comprising a stator assembly 21 fixed to the housing 10 and a rotor assembly 22 disposed on the inner circumferential side of the stator assembly 21 and spaced from the stator assembly 21, the stator assembly 21 driving the rotor assembly 22 to vibrate along the axial direction of the housing 10. The housing 10 is used to mount and fix the first motor unit 20 and the second motor unit 30.

[0046] The stator assembly 21 comprises a driving coil 211 fixed in the housing 10.

[0047] The rotor assembly 22 comprises a mass block 221 in a hollow cylindrical shape, a magnetic steel assembly 222 fixed to the outer circumferential side of the mass block 221, and a first cover plate 203 and a second cover plate 204 fixed to the opposite ends of the mass block 221 along the axial direction of the housing 10; the mass block 221 is spaced from the stator assembly 21, the magnetic steel assembly 222 is opposite to and spaced from the driving coil 211; the second motor unit 30 is fixed in the mass block 221, and one end of the second motor unit 30 close to the first cover plate 203 is fixed to the first cover plate 203; the driving coil 211 is energized to drive the magnetic steel assembly 222 to vibrate and / or the second motor unit 30 is energized to vibrate.

[0048] The hybrid motor 100 further comprises a first elastic member 40 and a second elastic member 50 oppositely disposed at the two ends of the rotor assembly 22, the outer circumferential side 404 of the first elastic member and the outer circumferential side 504 of the second elastic member are respectively fixed to the housing 10, one side of the first elastic member 40 close to the second motor unit 30 is fixed to the first cover plate 203, one side of the second elastic member 50 close to the second motor unit 30 is fixed to the second cover plate 204, and the first elastic member 40 and the second elastic member 50 together suspend the rotor assembly 22 in the housing 10, so as to provide vibration restoring force for the mass block 221 and the second motor unit 30 and improve the overall vibration performance of the hybrid motor 100.

[0049] The second motor unit 30 includes a rotor motor 301 fixed in the mass block 221 and an eccentric block 302 fixed to an output shaft 3011 of the rotor motor 301, the eccentric block 302 is spaced apart from the mass block 221 and the second cover plate 204 respectively, and the rotor motor 301 is fixed to the first cover plate 203 near one end of the first cover plate 203. The eccentric block 302 is driven to rotate by the rotor motor 301 after being energized to provide a vibration feeling for the hybrid motor 100. Optionally, the eccentric block 302 is spaced apart from the mass block 221 and the second cover plate 204 respectively, so that the mass block 221 and the second cover plate 204 do not affect the transmission path of the eccentric block 302 no matter how they are installed.

[0050] Specifically, the driving coil 211 is not connected with the second motor unit 30 and is energized separately. When the second motor unit 30 is energized and the driving coil 211 is not energized, the eccentric block 302 of the second motor unit 30 rotates, and the rotor motor 301 provides a vibration feeling. When the driving coil 211 is energized and the second motor unit 30 is not energized, the driving coil 211 is driven by the magnetic steel after being energized to drive the mass block 221 to reciprocate. When the driving coil 211 and the second motor unit 30 are energized at the same time, the driving coil 211 drives the mass block 221 to reciprocate after being energized, and the eccentric block 302 of the second motor unit 30 rotates, and the rotor motor 301 vibrates to provide a coupled vibration feeling. The motor couples rotation and linear motor in a smaller space, realizes three different motion modes of rotation, linear vibration, and rotation and linear vibration coupling, so as to realize rich vibration experience of multiple combinations, multiple modes, and multiple functions, and realize complex vibration experience scenes. At the same time, the second motor unit 30 is placed as a linear motor mover in the interior of the first motor unit 20, which increases the weight of the linear motor, improves the vibration feeling, and enables the linear motor to have excellent medium-high frequency performance and the low frequency performance of the rotor motor 301 in the conventional device size.

[0051] In the embodiment, the driving coil 211 includes a first coil 2111 and a second coil 2112 spaced apart along the axial direction of the shell 10 and fixed to the shell 10 respectively, the current directions of the first coil 2111 and the second coil 2112 are opposite, so that the resultant force directions of the Ampere forces are the same, and the driving force is larger.

The magnetization direction of the main magnetic steel 2222 is parallel to the axial direction of the shell 10. The first magnetic component 2221 and the second magnetic component 2223 facilitate the increase of the overall magnetic circuit density of the main magnetic steel 2222, and are beneficial to the improvement of the magnetic circuit driving force of the main magnetic steel 2222.

The motor vibration performance is realized by energizing the first coil 2111 and the second coil 2112 to drive the magnetic steel to rotate.

[0054] In the embodiment, the magnetization direction of the main magnetic steel 2222 is along the axial direction of the mover assembly 22. The reciprocating motion of the main magnetic steel 2222 along the axial direction of the mover assembly 22 driven by the energization of the first coil 2111 and the second coil 2112 provides the motor with a vibration feeling.

[0055] In an optional embodiment of the present application, when the driving coil 211 is one of the first coil 2111 or the second coil 2112, the magnetization direction of the first magnetic component 2221 and the second magnetic component 2223 is parallel to the axial direction of the shell 10, and the magnetization direction of the first magnetic component 2221 is opposite to the magnetization direction of the second magnetic component 2223; the magnetization direction of the main magnetic steel 2222 is perpendicular to the axial direction of the shell 10; the orthographic projection of the coil to the direction of the main magnetic steel 2222 completely falls within the range of the first magnetic component 2221, the second magnetic component 2223 and the main magnetic steel 2222 at the same time.

When the first outer arm 401 and the first inner arm 402 are arranged in a spaced manner along the radial direction of the first outer shell 101, the first outer arm 401 and the first inner arm 402 are no longer on the same plane, thereby forming a three-dimensional spring structure.
