[0028] Example:

[0029] like Figure 1-6As shown, this embodiment provides a vehicle control coil, including an enameled coil 6 and a coil frame 5. The coil frame 5 includes an I-shaped frame 51 with an I-shaped cross-section. The I-shaped frame 51 is hollow inside.

The ends of the two connecting beams 53 away from the floating platform 52 are fixedly connected to one side of the two insulating barriers 55 respectively. The I-shaped frame 51, connecting beams 53 and floating platform 52 are integrally formed. A pin 4 is embedded inside the integrally formed structure. The two pins 4 are symmetrically arranged with the center of the floating platform 52 as the origin. One end of the pin 4 passes through the floating platform 52 and is vertically arranged. The other end passes through the I-shaped frame 51 and is inside the insulating barrier 55. An insulating plate 56 is integrally formed at the center of the top of the floating platform 52. The insulating plate 56 is located between the two pins 4.

[0030] The enameled coil 6 is wound around the I-shaped frame 51. The two poles of the enameled coil 6 are respectively welded to one end of the two pins 4. One end of the two pins 4 at the floating platform 52 is respectively welded to the two poles of one end of the spring wire 2. An insulating cover 3 is provided on the top of the coil frame 5.

[0031] Specifically, such as Figure 1-2 As shown, the control coil for this vehicle is installed inside the electromagnetic damper module of the electric vehicle.

[0032] The assembly process is as follows:

[0033] The spring wire 2 and the terminal 1 are assembled into a wire harness riveting sub-assembly by riveting.

[0034] The pins 4 and plastic granules are assembled into a coil frame 5 assembly by injection molding.

[0035] The enameled coil 6 and coil frame 5 are assembled into coil sub-components by winding.

[0036] The coil components and wire harness riveting sub-assemblies are assembled into a coil component by welding wires.

[0037] The coil components and cover plate 32 are assembled into a vehicle control coil using an assembly method.

[0038] Compared to the single-arm cantilever design, the coil frame 5 of this coil assembly features a design where metal inserts are embedded in the injection molding at 180° angles, simultaneously providing support.

[0039] (1) It can effectively improve the deformation of cantilever beams caused by product cooling stress, which leads to unqualified product dimensions and affects assembly efficiency;

[0047] Specifically, such as Figure 5 As shown, the design of the evenly distributed clearance holes 58 and protrusions 57 around the bottom of the I-shaped frame 51 can effectively solve the problem of short circuit between the 6 turns of the enameled coil caused by a large impact force during assembly, and can also prevent abnormal noise caused by gaps generated after the product shrinks due to high and low temperatures.

[0048] In a preferred embodiment of this utility model, a positioning groove 59 is further provided on one side of the bottom edge of the I-shaped frame 51, which can effectively solve the problem of identifying and positioning the coil frame 5 in the direction during the winding process.
