[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-4 The utility model provides a technical solution: a micro vibration motor that is easy to assemble, including a first housing 1, a second housing 11, a front cover 4, a rear cover 41, and a stator and rotor 5. The first housing 1 and the second housing 11 are respectively integrally formed with skirt plates 3 at their edges on both sides, and the skirt plate 3 between the first housing 1 and the second housing 11 is installed with positioning bolts 7;

[0023] Insertion positioning grooves 2 are respectively provided at both ends of the inner walls of the first shell 1 and the second shell 11, and the front cover 4 and the rear cover 41 are respectively installed in the insertion positioning grooves 2 at both ends of the inner walls of the first shell 1 and the second shell 11;

[0024] The two ends of the stator and rotor 5 can be pre-selected to be assembled with the front end cover 4 and the rear end cover 41, and the plug-in positioning grooves 2 at the two ends of the inner wall of the first shell 1 and the second shell 11 of the arc structure can clamp the front end cover 4 and the rear end cover 41 of the stator and rotor 5 into a whole, so that the skirts 3 on both sides of the outer edge of the first shell 1 and the second shell 11 can be screwed into the corresponding screw sleeves 71 with positioning bolts 7. Compared with the existing micro-vibration motor assembly, it is not necessary to align the mounting holes at the inner corners of the frame-type heat dissipation shell of the micro-vibration motor with the mounting holes on the front end cover 4 and the rear end cover 41 and then connect them one by one with bolts, which can realize convenient assembly between the heat dissipation shell and the front end cover 4 and the rear end cover 41;

[0025] The two arc-shaped heat dissipation shells can be disassembled from the front cover 4 and the rear cover 41, and the first shell 1 and the second shell 11 can be placed together through adjacent surfaces to reduce the occupied space and facilitate the transportation of the assembled parts of the micro vibration motor.

[0026] Among them, the rotor part of the stator and rotor 5 movably penetrates to the top of the front end cover 4, and the top of the front end cover 4 is rotatably connected with a connecting tooth head 6. The top of the rotor part of the stator and rotor 5 is inserted into the inner diameter of the connecting tooth head 6. The rotating connecting tooth head 6 on the front end cover 4 facilitates the fixation of the subsequent output end connector of the stator and rotor 5.

[0027] Among them, the front end cover 4 and the rear end cover 41 are respectively inserted into the inner walls of the plug-in positioning grooves 2 at both ends of the inner walls of the first shell 1 and the second shell 11. The plug-in positioning grooves 2 at both ends of the inner walls of the arc-shaped first shell 1 and the second shell 11 can clamp the front end cover 4 and the rear end cover 41 of the stator and rotor 5 into a whole, so there is no need to align the mounting holes at the inner corners of the frame-type heat dissipation shell on the micro vibration motor with the mounting holes on the front end cover 4 and the rear end cover 41 and then connect them one by one with bolts.
