[0038] The wire clamping block 203b includes a guide rail 203b-1 provided at its bottom, an arc-shaped guide groove 203b-2 provided at the bottom of the wire clamping block 203b, a wire clamping triangle 203b-3 provided on one side of the wire clamping block 203b, and a first inclined surface 203b-4 provided at the top of the wire clamping triangle 203b-3.

[0040] Further, the core mechanism 204 further includes a limiting spring 204d provided between the top block 204c and the second hinge rod 204b;

[0041] The second hinge rod 204b includes a movable cavity 204b-1 provided at one end thereof.

[0042] Further, the insulating cover 205 includes a circular notch 205a and a sliding notch 205b penetratingly provided at its top, and a second inclined surface 205c provided at its upper end.

[0043] Further, the clutch gear 101 includes a clutch shaft 101a penetratingly provided at its center, and a fixed spline gear 101b provided on one side of the clutch gear 101;

[0044] The spline disc 102 meshes with the spline gear 101b; the spline disc 102 and the push ring 103 are respectively movably connected to the clutch shaft 101a; the spline disc 102 is engaged with the push ring 103 and is movably connected therebetween.

[0045] It should be noted that the electromagnetic clutch hardware includes a clutch controller, most of the clutch unit 100, an electromagnetic coil 104, and the electromagnetic clutch hardware in the hybrid special transmission includes: components such as a push ring 103, a return spring 105, a spline disc 102, a clutch gear 101, and a clutch shaft 101a.

[0046] Clutch open state: The clutch controller does not output current, the electromagnetic coil 104 does not generate magnetic force, the dog clutch disc 102 and the push ring 103 are pushed to the limit position by the return spring 105, the dog clutch disc 102 and the dog clutch gear 101b are not engaged, the clutch is in the open state, and the clutch gear 101 and the clutch shaft 101a are separated. Clutch engagement state: The clutch controller outputs the target current, the electromagnetic coil 104 generates magnetic force, attracts the push ring 103 to compress the return spring 105, the push ring 103 presses the dog clutch disc 102 to move, the dog clutch disc 102 engages with the dog clutch gear 101b, the clutch is in the engaged state, and the clutch gear 101 and the clutch shaft 101a are locked.

[0047] Preferably, this electromagnetic clutch mechanical structure has the advantages of simple structure, fewer components, and low cost, and the energy impact during the engagement process of the dog clutch disc 102 is small, and it is durable and reliable.

[0048] Preferably, the outer surface of the housing 201 should be coated or covered with insulating material, the whole is a conductive material, and its conductive ability needs to be ensured on the inner side. A plurality of movable holes 201a are opened at the middle position of the housing 201. The movable holes 201a are used to accommodate the connecting column 202c. The connecting column 202c connects the inner ring 202a and the outer ring 202b. When the outer ring 202b is rotated by a certain angle by a person, the inner ring 202a also rotates accordingly. The ratchet section 201b is between the plurality of movable holes 201a and is located inside the housing 201. The number of the ratchet sections 201b is the same as the number of intervals between the movable holes 201a. The travel piece 201d connected to the ratchet section 201b is located at the exact center inside the housing 201 to prevent excessive displacement of one copper core when the copper cores at both ends of the housing 201 are inserted, so that the other copper core cannot interact with the core clamping mechanism 204. The first hinge columns 201c are arranged in an array on the inner wall of the housing 201 and are symmetrically distributed up and down on the inner wall. The first hinge columns 201c are hinged to the first hinge rod 204a. The travel strips 201e are arranged in an array on the inner wall of the housing 201 and are symmetrically distributed. The travel strips 201e extend axially from both ends of the housing 201 towards the center, and the two ends of the travel strips 201e are not connected. The travel strips 201e can ensure the center alignment when the wire is inserted and also ensure that the copper core will not be greatly offset in the housing 201, so as to prevent it from being blocked by the core clamping mechanism 204 and continuing to move forward. A guide groove 201f is provided at the end of each travel strip 201e, and the guide groove 201f cooperates with the guide rail 203b-1 to enable the wire clamping block 203b to move radially along the end of the housing 201.

[0049] Preferably, the inner ring 202a of the lock core ring 202 moves inside the housing 201, and the outer ring 202b moves outside the housing 201. The lock core ring 202 is made of an insulating material with a certain flexibility, such as hard rubber, plastic, or derivatives of both. The second hinge post 202a-1 is hinged to the second hinge rod 204b. The number is the same as that of the first hinge rod 204a, and both are distributed in an array and symmetrically. The first paddles 202a-2 are arrayed inside the inner ring 202a, and their positions correspond to the ratchet segments 201b. The two cooperate with each other. Specifically, when the lock core ring 202 rotates clockwise, since the first paddles 202a-2 are made of flexible material, they can rotate smoothly when passing through the ratchet segments 201b. When the lock core ring 202 rotates counterclockwise, it will be blocked by the ratchet segments 201b. Therefore, the lock core ring 202 can only rotate in one direction. The same-direction ratchets 202b-1 are symmetrically distributed at both ends of the outer ring 202b, and their orientations are opposite to the ratchet directions of the ratchet segments 201b.

[0050] Preferably, the wire locking mechanism 203 can lock the insulating skin of the wire. Its material is the same as that of the lock core ring 202. The number of the guiding rings 203a is two. The guiding posts 203a-1 on the guiding rings 203a are arrayed and face the end of the housing 201. The number is the same as that of the wire clamping blocks 203b and cooperates with the arc-shaped guiding grooves 203b-2. When the guiding rings 203a rotate, the arc-shaped guiding grooves 203b-2 can be driven by the guiding posts 203a-1, so that several wire clamping blocks 203b can be telescoped simultaneously. The check pieces 203a-2 face the same-direction ratchets 202b-1, and the two cooperate with each other. When the lock core ring 202 rotates clockwise and the guiding rings 203a rotate counterclockwise, the two do not interfere with each other, that is, the operator can rotate the lock core ring 202 and the guiding rings 203a simultaneously, which is extremely convenient for the operator. Each end of the wire clamping block 203b has a wire clamping triangle 203b-3. When the wire clamping block 203b contracts, the wire clamping triangle 203b-3 can be pushed into the insulating skin of the wire to ensure the fixing effect of wire locking. A first inclined surface 203b-4 is arranged at the end of the wire clamping triangle 203b-3, and its function is the same as that of the second inclined surface 205c, both of which can ensure that the wire enters the power connection unit 200 smoothly.

[0051] Preferably, when the lock core ring 202 rotates clockwise, the core clamping mechanism 204 can hold and press against the copper core. Due to the one-way rotation characteristic of the lock core ring 202, the effect of the core clamping mechanism 204 pressing against the copper core will gradually increase. Due to the convenience of operation, the operator can rotate the guiding rings 203a in the reverse direction. At this time, the guiding rings 203a rotate counterclockwise and drive the wire clamping block 203b group to contract until it presses tightly against the insulating skin of the wire. Under the elastic reaction of the insulating skin, a reaction force is applied to the guiding rings 203a, and the reaction force makes the lock core ring 202 tend to rotate clockwise continuously, which can further strengthen the locking effect of the copper core. The guiding rings 203a on the other side are the same.

[0052] Preferably, the above-mentioned other-side guide ring 203a may be driven by the lock core ring 202 during rotation, and the arc-shaped guide groove 203b-2 on the other side will prevent the guide post 203a-1 on the other-side guide ring 203a from further rotating passively.

[0053] Preferably, the entire card core mechanism 204 is made of a conductive material. The first hinge rod 204a is hinged to the second hinge rod 204b. At the hinged position of the first hinge rod 204a and the second hinge rod 204b, a movable top block 204c is further provided. One side of the top block 204c is connected to the inner wall of the second hinge rod 204b through a limiting spring 204d to prevent the top block 204c from moving randomly. The top block 204c contacts and wraps the copper core. The contact surface of the top block 204c is C-shaped, and the material is made of metal copper with a certain toughness, so that the contact surface has a certain deformation ability to increase the fitting and wrapping effect. Driven by the first hinge rod 204a and the second hinge rod 204b, the top block 204c will deflect towards the copper core and will generate a certain offset. At this time, the limiting spring 204d can exert a reverse acting force on the top block 204c when the top block 204c undergoes a certain displacement, enhancing the clamping effect between the outer wall of the copper core and the top block 204c.

[0054] Preferably, the above-mentioned limiting spring 204d is staggered from the hinged positions of the first hinge rod 204a and the second hinge rod 204b to ensure that the reverse acting force exerted by the limiting spring 204d can be correctly applied to one side of the top block 204c.

[0055] Preferably, when the lock core ring 202 rotates clockwise, the first hinge rod 204a can push the second hinge rod 204b, so that the top block 204c gradually approaches the copper core.

[0056] Preferably, the insulating cover 205 can cover the remaining exposed part of the housing 201 to a great extent, preventing connection short circuits and electric shocks. The insulating cover 205 is fixedly connected to both ends of the housing 201 and can not hinder the activities of the wire clamping block 203b and the guide post 203a-1.

[0057] When in use, it is necessary to strip the insulation of two sections of wire to expose a certain length of copper core. Insert one section of the copper core into the interior of one end of the power connection unit 200 until it abuts against the travel piece 201d. At this time, due to the friction between the travel bar 201e and the insulation, the wire is not easily detached. Then, the user rotates the lock core ring 202 and the guide ring 203a in opposite directions. The lock core ring 202 rotates clockwise unidirectionally and, through the action of the first hinge rod 204a and the second hinge rod 204b, ejects the ejector block 204c. The ejector block 204c then wraps around the surface of the copper core and undergoes a certain deformation. At this time, the guide ring 203a rotates counterclockwise unidirectionally. The guide ring 203a drives the guide post 203a-1 and, through the action of the arc-shaped guide groove 203b-2, pushes the wire clamping block 203b. The wire clamping block 203b contracts, and its tip presses against the insulation until the guide ring 203a and the guide ring 203a reach the travel limit. At this time, the guide ring 203a and the guide ring 203a act against each other, making the effect of both more obvious. Finally, insert the other section of wire into the interior of the other end of the power connection unit 200 and repeat the above process. The difference from the above process is that the lock core ring 202 no longer rotates, while the guide ring 203a can rotate counterclockwise until the guide ring 203a rotates to the travel limit, completing the connection of the wire. The two sections of copper core, the housing 201, and the core clamping mechanism 204 complete the connection of the circuit.

[0058] In summary, this design can greatly improve the wiring efficiency during the process of energizing and wiring the electromagnetic coil in the electromagnetic clutch, ensuring the firmness of the connection between wires and the connectivity of the circuit.
