[0004] During the use of the existing magneto stator structure, during the long-term working state of the magneto stator, the magnetism may weaken or even lose magnetism, which may lead to problems in the operation of the magneto stator, inability to rotate normally, and inability to timely and quickly feedback problems, resulting in potential safety hazards.

[0005] Therefore, a vehicle magneto stator is proposed to solve the above problems. Content of the Utility Model

[0007] To achieve the above object, the utility model provides the following technical solution: a vehicle magneto stator, comprising a stator core, a rotor core is sleeved inside the stator core, embedding grooves are opened on the inner wall of the stator core, ventilation grooves are opened on the outer periphery of the stator core, and a magnetic detection component is embedded on the outer side of the stator core;

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 5 shown, the present invention provides a vehicle magneto stator, which includes a stator core 1. A rotor core 2 is sleeved inside the stator core 1. Embedding grooves 3 are provided on the inner wall of the stator core 1. Ventilation grooves 4 are provided around the outside of the stator core 1. The ventilation groove 4 structure can dissipate heat quickly. A magnetic detection component 5 is embedded on the outside of the stator core 1;

[0027] The magnetic detection component 5 includes a limit frame 51 fixedly arranged on the surface of the stator core 1. A U-shaped elastic piece 52 is fixedly arranged inside the limit frame 51. A pressure alarm 53 penetrates through the outside of the limit frame 51. The U-shaped elastic piece 52 can push against the surface of the pressure alarm 53 through an elastic structure design to give an alarm of pressure signal. The other end of the U-shaped elastic piece 52 is fixedly provided with a magnet 57 towards one side of the stator core 1, and the magnet 57 is magnetically attracted to the stator core 1. The magnetically attracted magnet 57 structure design can prevent the elastic rotation of the U-shaped elastic piece 52 from contacting the pressure alarm 53 and causing an accidental alarm.

[0028] Specifically, the pressure alarm 53 adopts an alarm of model LY-PA3000, and the detection end of the pressure alarm 53 is located on the side towards the U-shaped elastic piece 52. A baffle 54 is attached to the outside of the U-shaped elastic piece 52, and the baffle 54 is fixedly arranged with the limit frame 51 to reduce the influence of the high-temperature situation on the alarm. At the same time, the structure design of the baffle 54 can limit the maximum rotation range of the U-shaped elastic piece 52.

[0029] Furthermore, a damper 56 is fixedly arranged at one end of the U-shaped elastic piece 52 towards the limit frame 51. A spring 55 is sleeved outside the damper 56. The spring 55 is located between the limit frame 51 and the U-shaped elastic piece 52. The damper 56 and the spring 55 cooperate to play a buffering role to prevent excessive pressure on the pressure alarm 53 and damage the pressure alarm 53.

[0030] Furthermore, a heat dissipation and dustproof cover 6 is fitted inside the top end of the stator core 1, and a cover plate 7 is fitted inside the bottom end of the heat dissipation and dustproof cover 6. Heat dissipation grooves 9 are formed inside the heat dissipation and dustproof cover 6. Positioning pins 8 are fixedly arranged around the top end of the cover plate 7, and the positioning pins 8 are inserted into the heat dissipation and dustproof cover 6, which is convenient for quick assembly, forming a heat dissipation and protection cover structure to avoid affecting heat dissipation.

[0031] Among them, the stator core 1, the rotor core 2, and the pressure alarm 53 are prior arts and will not be elaborated here; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here.

[0032] Working principle and process:

[0033] When using the vehicle magneto stator, the limit frame 51 of the magnetic detection component 5 is installed on the outer side of the stator core 1. During the operation of the vehicle magneto stator, once the demagnetization occurs, the magnetic block 57 on one side of the U-shaped elastic piece 52 inside the limit frame 51 detaches from the stator core 1, and contacts the limit frame 51 through the buffer damper 56 and the spring 55 structure, avoiding excessive impact on the pressure alarm 53. At the same time, the pressure alarm 53 is pressed to give an alarm, and through signal transmission, the personnel are reminded to perform maintenance at any time, reducing potential safety hazards. After the remagnetization is completed, the magnetic block 57 adsorbs to the surface of the stator core 1, and the baffle 54 blocks the U-shaped elastic piece 52 to prevent it from hindering the normal operation of the stator core 1.

[0034] Moreover, the cover plate 7 can be installed at the bottom of the heat dissipation and dustproof cover 6 and positioned by the positioning pins 8. In the operating state, the wind or water can flow through the heat dissipation grooves 9 to effectively dissipate heat and reduce the entry of dust.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to this process, method, article or device.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
