[0033] It should be understood that the electrical appliance refers to a device that consumes electrical energy in a circuit.

[0034] For example, the electrical appliance can be a motor, a resistor, etc.

[0035] In the embodiment, as shown in Figure 1 and Figure 2 , the shell 1 comprises a box body 11 and a cover plate 12 arranged on the box body 11, the box body 11 and the cover plate 12 are detachably connected, and the input electrode group 2 and the output electrode group 3 are located in the box body 11.

[0037] As shown in Figure 1 and Figure 2 , the cover plate 12 is provided with first through holes 101 and second through holes 102 spaced apart from each other, wherein the first through holes 101 are two, respectively corresponding to the input positive electrode 21 and the input negative electrode 22 of the input electrode group 2; the second through holes 102 are two, respectively corresponding to the first output electrode 31 and the second output electrode 32 of the output electrode group 3.

[0038] Further, the conductive connecting piece 4 comprises a first conductive connecting part 41 and a second conductive connecting part 42 movably connected in the box body 11, the first conductive connecting part 41 and the second conductive connecting part 42 are arranged in insulation with each other; the conductive connecting piece 4 has a forward conduction position and a reverse conduction position which can be switched with each other; when the conductive connecting piece 4 is located at the forward conduction position, the first conductive connecting part 41 is conductively connected with the input positive pole 21 and the first output pole 31, and the second conductive connecting part 42 is conductively connected with the input negative pole 22 and the second output pole 32; when the conductive connecting piece 4 is located at the reverse conduction position, the first conductive connecting part 41 is conductively connected with the input positive pole 21 and the second output pole 32, and the second conductive connecting part 42 is conductively connected with the input negative pole 22 and the first output pole 31.

[0039] In the embodiment, when the conductive connecting piece 4 is located at the forward conduction position, the first conductive connecting part 41 is conductively connected with the input positive pole 21 and the first output pole 31, and the second conductive connecting part 42 is conductively connected with the input negative pole 22 and the second output pole 32, so that the first output pole 31 outputs positive ions and the second output pole 32 outputs negative electrons after the input positive pole 21 and the input negative pole 22 are conductively connected with the positive pole and the negative pole of the power supply. Meanwhile, when the conductive connecting piece 4 is switched from the forward conduction position to the reverse conduction position, the first conductive connecting part 41 is conductively connected with the input positive pole 21 and the second output pole 32, and the second conductive connecting part 42 is conductively connected with the input negative pole 22 and the first output pole 31, so that the first output pole 31 outputs negative electrons and the second output pole 32 outputs positive ions after the input positive pole 21 and the input negative pole 22 are conductively connected with the positive pole and the negative pole of the power supply.

[0040] Therefore, the relay only needs to switch the conductive connecting piece 4 between the forward conduction position and the reverse conduction position, so that the relay can realize the switching function of the contact polarity.

[0041] It should be understood that if the electrical appliance is a motor, the relay can realize the forward and reverse rotation of the motor.

[0042] In combination Figure 1 As shown in the figure, the first conductive connecting part 41 comprises a first positive pole conductive part 411 and a second positive pole conductive part 412 which are connected in insulation with each other; the second conductive connecting part 42 comprises a first negative pole conductive part 421 and a second negative pole conductive part 422 which are connected in insulation with each other.

[0043] In this embodiment, the first positive conductive portion 411 is connected to the second positive conductive portion 412, and an insulating layer is provided at the connection position between the first positive conductive portion 411 and the second positive conductive portion 412 to prevent conductive connection between the first positive conductive portion 411 and the second positive conductive portion 412. The first negative conductive portion 421 is connected to the second negative conductive portion 422, and an insulating layer is provided at the connection position between the first negative conductive portion 421 and the second negative conductive portion 422 to prevent conductive connection between the first negative conductive portion 421 and the second negative conductive portion 422.

[0044] Combine Figure 1 and Figure 4 As shown, when the conductive connector 4 is in the forward conducting position, the first positive conductive portion 411 is conductively connected to the input positive electrode 21 and the first output electrode 31 , and the first negative conductive portion 421 is conductively connected to the input negative electrode 22 and the second output electrode 32 .

[0045] In this embodiment, when the conductive connector 4 is in the forward conduction position, the current flows from the input positive pole 21 to the first output pole 31 through the first positive conductive portion 411, then flows from the first output pole 31 to the electrical appliance, then flows from the electrical appliance to the second output pole 32, and finally flows from the second output pole 32 to the input negative pole 22 through the first negative conductive portion 421, so that the first output pole 31 becomes the output positive pole and the second output pole 32 becomes the output negative pole, so as to realize forward conduction of the electrical appliance.

[0046] Combine Figure 1 and Figure 5 As shown, when the conductive connector 4 is in the reverse conduction position, the second positive conductive portion 412 is conductively connected to the input positive electrode 21 and the second output electrode 32 , and the second negative conductive portion 422 is conductively connected to the input negative electrode 22 and the first output electrode 31 .

[0047] In this embodiment, when the conductive connector 4 is in the reverse conduction position, the current flows from the input positive pole 21 to the second output pole 32 through the second positive conductive portion 412, then flows from the second output pole 32 to the electrical appliance, then flows from the electrical appliance to the first output pole 31, and finally flows from the first output pole 31 to the input negative pole 22 through the second negative conductive portion 422, so that the first output pole 31 becomes the output negative pole and the second output pole 32 becomes the output positive pole, so as to realize reverse conduction of the electrical appliance.

[0048] In the embodiment, the electric appliance is forwardly conducted through the first positive conductive part 411 and the first negative conductive part 421 and reversely conducted through the second positive conductive part 412 and the second negative conductive part 422, so that the polarity of the first output pole 31 and the second output pole 32 can be reversed according to the conductive connection mode of the conductive connecting piece 4, to change the direction of the current conducting electric appliance.

[0049] It should be understood that the polarity is positive or negative.

[0050] In combination Figures 1 to 3 As shown, the second positive conductive part 412 includes a first positive connecting end 412a and a second positive connecting end 412b, the first positive connecting end 412a is one-to-one corresponding to the two opposite sides of the input positive pole 21 along the first direction x, and the second positive connecting end 412b is one-to-one corresponding to the two opposite sides of the second output pole 32 along the first direction x.

[0051] In the embodiment, the second positive conductive part 412 is a "Z-shaped structure", the second positive conductive part 412 includes the first positive connecting end 412a, the second positive connecting end 412b and an intermediate positive connecting end 412c, the intermediate positive connecting end 412c is connected between the first positive connecting end 412a and the second positive connecting end 412b. When the conductive connecting piece 4 is located at the reverse conducting position, the input positive pole 21 is conductively connected with the first positive connecting end 412a, and the second output pole 32 is conductively connected with the second positive connecting end 412b, to realize the reverse conducting electric appliance.

[0052] It should be understood that when the conductive connecting piece 4 is located at the forward conducting position or the reverse conducting position, the relay is in a working state; when the conductive connecting piece 4 is located at a position other than the forward conducting position and the reverse conducting position, the relay is in an unworking state. Therefore, when the relay is in the unworking state, the input positive pole 21 is spaced apart from the first positive connecting end 412a and the first positive conductive part 411, and the second output pole 32 is spaced apart from the second positive connecting end 412b and the first negative conductive part 421.

[0053] In combination Figures 1 to 3 As shown, the second negative conductive part 422 includes a first negative connecting end 422a and a second negative connecting end 422b, the first negative connecting end 422a is one-to-one corresponding to the two opposite sides of the input negative pole 22 along the first direction x, and the second negative connecting end 422b is one-to-one corresponding to the two opposite sides of the first output pole 31 along the first direction x.

[0054] In this embodiment, the second negative conductive portion 422 has a "Z-shaped structure" and includes a first negative electrode connection terminal 422a, a second negative electrode connection terminal 422b, and an intermediate negative electrode connection terminal 422c. The intermediate negative electrode connection terminal 422c is connected between the first negative electrode connection terminal 422a and the second negative electrode connection terminal 422b. When the conductive connector 4 is in the reverse conducting position, the input negative electrode 22 is conductively connected to the first negative electrode connection terminal 422a, and the first output electrode 31 is conductively connected to the second negative electrode connection terminal 422b, thereby achieving reverse conducting universal electrical equipment.

[0055] It should be understood that when the relay is in the non-operating state, the input negative electrode 22 is spaced apart from the first negative electrode connection terminal 422a and the first negative electrode conductive portion 421 , and the first output electrode 31 is spaced apart from the second negative electrode connection terminal 422b and the first positive electrode conductive portion 411 .

[0056] In this embodiment, combined with Figures 1 to 3 As shown, the first positive electrode connection terminal 412a and the second negative electrode connection terminal 422b are arranged opposite to the first positive conductive part 411 along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position; the second positive electrode connection terminal 412b and the first negative electrode connection terminal 422a are arranged opposite to the first negative conductive part 421 along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position; the intermediate positive electrode connection terminal 412c and the intermediate negative electrode connection terminal 422c overlap along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position.

[0057] It should be understood that the direction in which the conductive connecting member 4 switches between the forward conducting position and the reverse conducting position is the first direction x.

[0058] Combine Figure 1 As shown, along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position: the first negative conductive portion 421 is located between the input positive electrode 21 and the input negative electrode 22, and the first positive conductive portion 411 is located on the side of the input positive electrode 21 away from the first negative conductive portion 421.

[0059] Combine Figure 1 As shown, along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position: the first negative conductive portion 421 is located between the first output pole 31 and the second output pole 32, and the first positive conductive portion 411 is located on the side of the first output pole 31 away from the first negative conductive portion 421.

[0060] In this embodiment, combined with Figure 2 and Figure 3As shown, the first positive electrode conductive part 411 is in a "T-shaped structure", the first positive electrode conductive part 411 comprises a first positive electrode conductive segment 411a and a connecting segment 411b connected with each other, the connecting segment 411b is connected with the first positive electrode connecting end 412a and the second negative electrode connecting end 422b along the first direction x and insulated from each other, the first positive electrode conductive segment 411a is used for conductive connection with the input positive electrode 21 and the first output electrode 31, and the connecting segment 411b is used for connecting the first positive electrode conductive segment 411a with the first positive electrode connecting end 412a and the second negative electrode connecting end 422b.

[0061] In the embodiment, the first positive electrode conductive part 411 is connected with the first positive electrode connecting end 412a and the second negative electrode connecting end 422b along the first direction x. Figures 1 to 3 As shown, the box body 11 comprises a first side plate 111 and a second side plate 112 arranged opposite along the first direction x, and the first side plate 111 is closer to the input positive electrode 21 and the first output electrode 31 than the second side plate 112. The first positive electrode conductive segment 411a is closer to the first side plate 111 than the input positive electrode 21 and the first output electrode 31, and the first negative electrode conductive part 421 is closer to the first side plate 111 than the input negative electrode 22 and the second output electrode 32, so that the first positive electrode conductive segment 411a and the first negative electrode conductive part 421 can be conductively connected with the input electrode group 2 and the output electrode group 3 at the same time when the conductive connecting piece 4 moves away from the first side plate 111, to realize the forward conduction of the electric appliance.

[0062] It should be understood that the distance between the first positive electrode conductive segment 411a and the input positive electrode 21 and the first output electrode 31 is equal to the distance between the first negative electrode conductive part 421 and the input negative electrode 22 and the second output electrode 32, to ensure that the first positive electrode conductive segment 411a and the first negative electrode conductive part 421 can be conductively connected with the input electrode group 2 and the output electrode group 3 at the same time.

[0063] In combination with the above, Figure 1 and Figure 3 As shown, the relay further comprises a first elastic assembly 5 connected between the first positive electrode conductive segment 411a and the first side plate 111 along the direction in which the conductive connecting piece 4 switches between the forward conduction position and the reverse conduction position.

[0064] In the embodiment, when the conductive connecting piece 4 is located at the forward conduction position, the first positive electrode conductive segment 411a is conductively connected with the input positive electrode 21 and the first output electrode 31, the first elastic assembly 5 is stretched, and the elastic restoring force of the first elastic assembly 5 enables the conductive connecting piece 4 to switch from the forward conduction position to the non-conduction position, so as to switch the relay from the working state to the non-working state.

[0065] At the same time, when the conductive connector 4 is in the reverse conducting position, the first positive electrode connection terminal 412a is conductively connected to the input positive electrode 21, and the first output electrode 31 is conductively connected to the second negative electrode connection terminal 422b. The first elastic component 5 is compressed, and the elastic restoring force of the first elastic component 5 enables the conductive connector 4 to switch from the reverse conducting position to the non-conducting position, thereby facilitating the relay to switch from an operating state to a non-operating state. In addition, after the first elastic component 5 is compressed, the first elastic component 5 can also prevent the first positive electrode conductive segment 411a from colliding with the first side plate 111.

[0066] It should be understood that the non-conductive position means that the conductive connecting member 4 is not conductively connected to the input electrode group 2 and the output electrode group 3 .

[0067] Combine Figure 1 and Figure 3 As shown, the relay also includes a second elastic component 6, which includes a first elastic member 61 and a second elastic member 62 arranged relatively to each other along the second direction y; wherein the first elastic member 61 is connected between the second positive connection terminal 412b and the second side plate 112, and is located on the side of the second positive connection terminal 412b away from the second output pole 32 along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position; the second elastic member 62 is connected between the first negative connection terminal 422a and the second side plate 112, and is located on the side of the first negative connection terminal 422a away from the input negative pole 22 along the direction in which the conductive connector 4 switches between the forward conduction position and the reverse conduction position.

[0068] In this embodiment, the first elastic member 61 is connected between the second side plate 112 and the side of the second positive electrode connection terminal 412b away from the second output electrode 32, and the second elastic member 62 is connected between the second side plate 112 and the side of the first negative electrode connection terminal 422a away from the input negative electrode 22.

[0069] In this embodiment, when the conductive connector 4 is in the forward conducting position, the first negative electrode conductive portion 421 is electrically connected to the input negative electrode 22 and the second output electrode 32, and the first elastic member 61 and the second elastic member 62 are compressed. The elastic restoring force of the first elastic member 61 and the second elastic member 62 enables the conductive connector 4 to switch from the forward conducting position to the non-conducting position, thereby facilitating the relay to switch from an operating state to a non-operating state. Furthermore, after the first elastic member 61 and the second elastic member 62 are compressed, the first elastic member 61 can prevent the second positive electrode connection terminal 412b from colliding with the second side plate 112, and the second elastic member 62 can prevent the first negative electrode connection terminal 422a from colliding with the second side plate 112.

[0070] At the same time, when the conductive connector 4 is in the reverse conduction position, the first negative electrode connection terminal 422a is conductively connected to the input negative electrode 22, and the second positive electrode connection terminal 412b is conductively connected to the second output electrode 32, the first elastic member 61 and the second elastic member 62 are stretched, and the elastic recovery force of the first elastic member 61 and the second elastic member 62 enables the conductive connector 4 to switch from the reverse conduction position to the non-conduction position, so as to facilitate the relay to switch from the working state to the non-working state.

[0071] In this embodiment, combined with Figure 1 and Figure 3 As shown, the first elastic component 5 includes a third elastic member 51 and a fourth elastic member 52 arranged relatively along the second direction y, the third elastic member 51 and the second elastic member 62 are arranged relatively along the first direction x, and the fourth elastic member 52 and the first elastic member 61 are arranged relatively along the first direction x, so that when the conductive connecting member 4 switches between the forward conducting position and the reverse conducting position, the first elastic component 5 and the second elastic component 6 can cooperate with each other, which is conducive to ensuring that the force on the conductive connecting member 4 is more balanced.

[0072] It should be understood that when the relay is in a non-operating state, the first elastic component 5 and the second elastic component 6 are in a normal state, that is, not compressed or stretched.

[0073] In this embodiment, the first elastic member 61 , the second elastic member 62 , the third elastic member 51 and the fourth elastic member 52 are all springs.

[0074] Combine Figure 1 As shown, the relay further includes a driving mechanism 7, which is connected to the conductive connecting member 4, so as to drive the conductive connecting member 4 to switch between a forward conducting position and a reverse conducting position.

[0075] In this embodiment, the conductive connector 4 is switched between the forward conduction position and the reverse conduction position by the driving mechanism 7, so that the conductive connection mode between the input positive pole 21 and the input negative pole 22 of the input electrode group 2 and the first output pole 31 and the second output pole 32 of the output electrode group 3 is changed, thereby adjusting the conduction direction of the electrical appliance.

[0076] Combine Figure 1 and Figure 6 As shown, the driving mechanism 7 includes a first electromagnetic driving part 71, a first wire segment 72 connected to the positive pole of the first electromagnetic driving part 71, a second electromagnetic driving part 73, a second wire segment 74 connected to the positive pole of the second electromagnetic driving part 73, and a common wire segment 75 connected to the negative pole of the first electromagnetic driving part 71 and the negative pole of the second electromagnetic driving part 73.

[0077] In the embodiment, when the first wire segment 72 inputs current, the common wire segment 75 outputs current, and the second wire segment 74 is disconnected, the first electromagnetic driving part 71 is energized and generates a magnetic field, and the second electromagnetic driving part 73 is not energized; when the second wire segment 74 inputs current, the common wire segment 75 outputs current, and the first wire segment 72 is disconnected, the second electromagnetic driving part 73 is energized and generates a magnetic field, and the first electromagnetic driving part 71 is not energized; when the first wire segment 72, the second wire segment 74, and the common wire segment 75 are all disconnected, the first electromagnetic driving part 71 and the second electromagnetic driving part 73 are not energized.

[0078] It should be understood that, in the automatic control circuit, the relay is actually an "automatic switch" for controlling a larger current with a smaller current. Therefore, the current input to the driving mechanism 7 is not the same as the current input to the electrode group 2.

[0079] Further, the relay further comprises a magnetic transmission member 8, which is in transmission connection with the conductive connecting member 4, and is located between the first electromagnetic driving part 71 and the second electromagnetic driving part 73, and can be displaced when the first electromagnetic driving part 71 or the second electromagnetic driving part 73 is energized, so as to drive the conductive connecting member 4 to switch between the forward conduction position and the reverse conduction position.

[0080] In the embodiment, the magnetic transmission member 8 is in insulated connection with the intermediate positive connecting end 412c and the intermediate negative connecting end 422c. The first positive conductive part 411, the second positive conductive part 412, the first negative conductive part 421, the second negative conductive part 422, and the magnetic transmission member 8 form an integral whole without relative motion, and the conductive connecting member 4 is switched between the forward conduction position and the reverse conduction position by the movement of the magnetic transmission member 8 between the first electromagnetic driving part 71 and the second electromagnetic driving part 73.

[0081] In the embodiment, as shown in Figure 1 and Figure 5 , the first electromagnetic driving part 71 is closer to the first side plate 111 than the second electromagnetic driving part 73. After the first electromagnetic driving part 71 is energized and generates a magnetic field, the first electromagnetic driving part 71 will attract the magnetic transmission member 8, so that the magnetic transmission member 8 moves towards the first electromagnetic driving part 71, and then drives the conductive connecting member 4 to move towards the first side plate 111, so as to drive the conductive connecting member 4 to move to the reverse conduction position.

[0082] In the embodiment, as shown in Figure 1 and Figure 4As shown, after the second electromagnetic driving part 73 is powered on and generates a magnetic field, the second electromagnetic driving part 73 will attract the magnetic transmission part 8, so that the magnetic transmission part 8 moves towards the direction close to the second electromagnetic driving part 73, and then drives the conductive connecting part 4 to move away from the first side plate 111 through the magnetic transmission part 8, so as to drive the conductive connecting part 4 to move to the forward conduction position.

[0083] In this embodiment, one of the first electromagnetic driving part 71 and the second electromagnetic driving part 73 is powered on alternatively, and there is no case of simultaneous power-on of the two, so that the forward conduction and reverse conduction of the electric appliance can be realized alternatively, so as to ensure the safety and reliability of the relay.

[0084] It should be understood that when neither the first electromagnetic driving part 71 nor the second electromagnetic driving part 73 is powered on, the magnetic transmission part 8 is located between the first electromagnetic driving part 71 and the second electromagnetic driving part 73, and is spaced apart from the first electromagnetic driving part 71 and the second electromagnetic driving part 73, so as to ensure that the conductive connecting part 4 is not conductively connected with the input electrode group 2 and the output electrode group 3.

[0085] For example, the magnetic transmission part 8 can be an iron sheet, an iron block, etc.

[0086] In this embodiment, the relay not only has a simple structure, but also can realize the forward conduction and reverse conduction of the electric appliance through fewer components; and is easy to produce, and the components of the relay can be manufactured through common machining processes, which is conducive to reducing the cost.

[0087] It should be understood that the size specifications of the relay can be developed according to different use conditions.

[0088] In other embodiments, the first positive conductive part 411 can have a "one-word structure", and is insulatedly connected with the first positive connecting end 412a and the second negative connecting end 422b through the insulating plate, i.e., along the first direction x, the first positive conductive part 411 is located on the side of the insulating plate close to the first side plate 111, and the first positive connecting end 412a and the second negative connecting end 422b are located on the side of the insulating plate away from the first side plate 111, so as to integrate the first positive conductive part 411 with the first positive connecting end 412a and the second negative connecting end 422b.

[0089] In addition, the first negative conductive part 421 can also be insulatedly connected with the second positive connecting end 412b and the first negative connecting end 422a through the insulating plate, i.e., along the first direction x, the first negative conductive part 421 is located on the side of the insulating plate close to the first side plate 111, and the second positive connecting end 412b and the first negative connecting end 422a are located on the side of the insulating plate away from the first side plate 111, so as to integrate the first negative conductive part 421 with the second positive connecting end 412b and the first negative connecting end 422a.

[0090] In other embodiments, the input positive electrode 21 of the input electrode group 2 and the input negative electrode 22 and the first output electrode 31 and the second output electrode 32 of the output electrode group 3 are all in a "U-shaped structure", the opening of the input positive electrode 21 and the opening of the first output electrode 31 are oppositely arranged along the second direction y, and the opening of the input negative electrode 22 and the opening of the second output electrode 32 are oppositely arranged along the second direction y.

[0091] In other embodiments, the first positive electrode conductive part 411 and the first positive electrode connecting end 412a and the second negative electrode connecting end 422b form a whole located between the opening of the input positive electrode 21 and the opening of the first output electrode 31, and when the conductive connecting piece 4 is located in the forward conduction position and the reverse conduction position, it will be conductively connected with the input positive electrode 21 and the first output electrode 31; the first negative electrode conductive part 421 and the second positive electrode connecting end 412b and the first negative electrode connecting end 422a form a whole located between the opening of the input negative electrode 22 and the opening of the second output electrode 32, and when the conductive connecting piece 4 is located in the forward conduction position and the reverse conduction position, it will be conductively connected with the input negative electrode 22 and the second output electrode 32.

[0092] The embodiment also provides a vehicle comprising a motor and the above-mentioned relay, the motor being connected with the relay.

[0093] In the embodiment, the motor is conductively connected with the first output electrode 31 and the second output electrode 32 to realize forward and reverse rotation of the motor.
