Description

Technical Field

[0001] The utility model relates to a generator, in particular to a generator for automobiles. Background Art

[0002] The automobile generator is the main power source of the car. Structurally, the automobile generator is mainly composed of a rotor, a stator, a rectifier and an end cover.

[0003] In the prior art, the front cover and the rear cover are generally closed at the position of the stator, that is, the front cover and the rear cover are closed to enclose various components in the end covers. Since the diameter of the stator core is relatively large, the front cover and the rear cover need to be radially extended outward for a period of time before they can be completely enclosed inside, which wastes materials. Utility Model Content

[0004] In order to overcome the disadvantage that the end cover needs to completely seal the stator core due to the large diameter of the stator core, resulting in a large waste of materials, the utility model provides an automobile generator with reduced end cover material consumption.

[0005] A generator for automobile includes an electric motor, which is composed of a front end cover, a rear end cover and a stator. The stator includes an iron core and an enameled wire wound on the iron core. The front end cover is directly closed at the front end of the iron core, and the rear end cover is directly closed at the rear end of the iron core.

[0006] A more excellent solution is that there is a gap between the front cover and the rear cover, and the length of the gap is the length of the front and rear ends of the stator core.

[0007] A more excellent solution is to further include a sealing ring, the sealing ring is provided with a slot, and the sealing ring is connected to the front end cover and the rear end cover through the slot.

[0008] A more excellent solution is that the sealing ring is provided with fixing screws, and the fixing screws can fix the sealing ring to the front cover and the rear cover.

[0009] A better solution is to embed a rubber strip in the card slot.

[0010] A more excellent solution is to further include a protective cover which is clamped on the end of the motor.

[0011] A better solution is to provide a handle on the side of the protective cover.

[0012] A more excellent solution is that axial protrusions are provided on the protective sleeve at equal intervals.

[0013] The beneficial effect is that when the front cover and the rear cover of the device fix the stator, they do not need to extend in the radial direction to cover the stator, and do not need to be in full contact. Only the front and rear ends of the stator are fixed, which saves the manufacturing material of the end cover and saves cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] Embodiment: A generator for automobile, such as Figure 1-Figure 4 As shown, it includes an electric motor 1, which is composed of a front end cover 2, a rear end cover 3 and a stator 4. The stator 4 includes an iron core and an enameled wire wound on the iron core, and is characterized in that the front end cover 2 is directly closed at the front end of the iron core, and the rear end cover 3 is directly closed at the rear end of the iron core.

[0021] There is a certain distance between the front end cover 2 and the rear end cover 3 at the closed position, and the distance is the width of the front and rear ends of the stator 4 core, that is, the stator 4 core is exposed to the outside, so that the front end cover 2 and the rear end cover 3 no longer need to extend in the radial direction for a section when closed, and do not need to be completely in contact, which saves the manufacturing material of the end cover and saves cost.

[0022] It also includes a sealing ring 6, which is provided with a slot 5. The sealing ring 6 is connected to the front cover 2 and the rear cover 3 through the slot 5. A rubber strip 8 is embedded in the slot 5. The sealing ring 6 is provided with a fixing screw 7. The fixing screw 7 can fix the sealing ring 6 to the front cover 2 and the rear cover 3. The sealing ring 6 provides external protection for the stator 4. The sealing ring 6 is made of a cheaper material than the end cover, which can provide external protection and reduce costs.

[0023] The motor 1 further comprises a protective sleeve 9 which is clamped at the end of the motor 1 to provide external protection for the motor 1 . A handle 10 is arranged on the side of the protective sleeve 9 . Axial protrusions 11 are equidistantly arranged on the protective sleeve 9 . The protrusions 11 are made of rubber material.
