Problems solved by technology

[0002] The automobile generator is mainly to provide electric energy for the automobile when the automobile is working normally. With the increase of the number of automobiles, the demand for the automobile generator is also increasing. Since the environment of the automobile is relatively complicated, the automobile generator should also meet various demands. The use requirements in the environment, such as figure 1 As shown, it is a cross-sectional view of the rotor coil 01 of the existing automobile generator. After the rotor coil is wound on the bobbin, the outer surface of the rotor coil is easily grounded, resulting in unstable performance of the entire generator

Embodiment 1

[0026] Such as Figure 2-6 As shown, a high-slot full-rate rotor former with self-locking anti-collapse function includes a central winding column 10, an upper stop plate 11 arranged at the upper end of the central winding column 10, and an upper stop plate 11 arranged at the lower end of the central winding column 10. The lower stopper 12 and the coil wrap protection mechanism 14 connected with the lower stopper 12 and the upper stopper 11.

[0027] The central winding column 10, the upper stopper 11 and the lower stopper 12 form a coil accommodation area, the coil accommodation area is the largest volume of the coil wound on the central winding column 10, the size of the coil accommodation area It is determined according to the size of the coil wound on the central winding column 10 , and the coil is determined according to the product specifications during actual production.

[0028] The coil wrapping protection mechanism 14 is used to wrap and protect the coil accommodati...

Embodiment 2

[0032] Based on embodiment 1, the difference from embodiment 1 is:

[0033] Such as figure 2 , image 3 As shown, the coil wrapping protection mechanism 14 includes a stopper 2 with one end disposed on the upper stopper 11 , and the other end of the stopper 2 is connected to a clip 3 arranged on the lower stopper 12 .

[0034] The blocking member 2 includes a folding blocking portion 21 that can be folded toward the clamping member 3. The end of the folding blocking portion 21 extends toward the clamping member 3 and is provided with a connecting portion 22, and the connecting portion 22 is connected to the locking member 3. The card firmware 3 is connected. The connecting portion 22 is provided with locking teeth 221, and the locking teeth 221 are inserted into the locking holes 31 provided in the clamping member 3, and can cooperate with the locking teeth 31 in the locking holes 31. The limiting teeth 311 of the teeth 221 are connected.

[0035] The blocking member 2 an...

Embodiment 3

[0037] Based on embodiment 1, the difference from embodiment 2 is:

[0038] Such as figure 2 , Figure 4 As shown, the folding blocking portion 21 is an elastic blocking portion, the connecting portion 22 includes a hook-shaped connecting head 222, and the locking member 3 is provided with an engaging groove 32 recessed toward the connecting portion 22. , the hook-shaped connecting head 222 can be connected with the engaging groove 32 and accommodated in the engaging groove 32 and fixedly limited by the engaging groove 32 .

Abstract

The invention relates to the technical field of automobile power generators, particularly to a high-slot-space-factor rotor coil rack with a self-locking collapse prevention function. The high-slot-space-factor rotor coil rack comprises a central winding column, an upper baffle disc arranged at the upper end of the central winding column, a lower baffle disc arranged at the lower end of the central winding column, and a coil wrapping protection mechanism connected with the lower baffle disc and the upper baffle disc. According to the invention, the coil wrapping protection mechanism is used for reinforcing and protecting the coil wound on the central winding column, the situation that the performance of the whole power generator is unstable due to the fact that the outer surface of the loosened rotor coil is prone to grounding is avoided, the working stability of the motor is improved, and the motor safety and production safety are guaranteed.
