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

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

[0035] In this embodiment, combined with Figure 1 and Figure 2 As shown, the housing 1 includes a box body 11 and a cover plate 12 covering 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 both located in the box body 11.

[0036] In this embodiment, the first direction x is the length direction of the box body 11 , and the second direction y is the width direction of the box body 11 .

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

[0038] Furthermore, the conductive connector 4 includes a first conductive connector part 41 and a second conductive connector part 42 movably connected to the box body 11, and the first conductive connector part 41 and the second conductive connector part 42 are insulated from each other; the conductive connector 4 has a forward conduction position and a reverse conduction position that can be switched with each other; wherein, when the conductive connector 4 is in the forward conduction position, the first conductive connector part 41 is conductively connected to the input positive pole 21 and the first output pole 31, and the second conductive connector part 42 is conductively connected to the input negative pole 22 and the second output pole 32; when the conductive connector 4 is in the reverse conduction position, the first conductive connector part 41 is conductively connected to the input positive pole 21 and the second output pole 32, and the second conductive connector part 42 is conductively connected to the input negative pole 22 and the first output pole 31.

[0039] In this embodiment, when the conductive connector 4 is in the forward conducting position, it can be conductively connected to the input positive electrode 21 and the first output electrode 31 through the first conductive connecting portion 41, and the second conductive connecting portion 42 is conductively connected to the input negative electrode 22 and the second output electrode 32, and then after the input positive electrode 21 is conductively connected to the positive electrode of the power source, and the input negative electrode 22 is conductively connected to the negative electrode of the power source, the first output electrode 31 can output positive ions, and the second output electrode 32 can output negative electrons.

[0040] Therefore, the relay can realize the contact polarity reversal function by only switching the conductive connecting member 4 between the forward conducting position and the reverse conducting position.

[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] Combination Figure 1 As shown, the first conductive connection part 41 includes a first positive conductive part 411 and a second positive conductive part 412 that are insulated from each other; the second conductive connection part 42 includes a first negative conductive part 421 and a second negative conductive part 422 that are insulated from 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 for isolating the first positive conductive portion 411 from the second positive conductive portion 412 is provided at the connection position between the first positive conductive portion 411 and the second positive conductive portion 412, so as to prevent the first positive conductive portion 411 from being conductively connected to 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 for isolating the first negative conductive portion 421 from the second negative conductive portion 422 is provided at the connection position between the first negative conductive portion 421 and the second negative conductive portion 422, so as to prevent the first negative conductive portion 421 from being conductively connected to the second negative conductive portion 422.

[0044] Combination Figure 1 and Figure 4 As shown, when the conductive connector 4 is in the forward conduction 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 electrode 21 to the first output electrode 31 through the first positive conductive portion 411, then from the first output electrode 31 to the electrical appliance, then from the electrical appliance to the second output electrode 32, and finally from the second output electrode 32 to the input negative electrode 22 through the first negative conductive portion 421, so that the first output electrode 31 becomes the output positive electrode and the second output electrode 32 becomes the output negative electrode, so as to realize forward conduction of the electrical appliance.

[0046] Combination 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 electrode 21 to the second output electrode 32 through the second positive conductive portion 412, then flows from the second output electrode 32 to the electrical appliance, then flows from the electrical appliance to the first output electrode 31, and finally flows from the first output electrode 31 to the input negative electrode 22 through the second negative conductive portion 422, so that the first output electrode 31 becomes the output negative electrode and the second output electrode 32 becomes the output positive electrode, so as to realize reverse conduction of the electrical appliance.

[0048] In this embodiment, the first positive conductive portion 411 and the first negative conductive portion 421 are used to conduct the general electrical appliance forward, and the second positive conductive portion 412 and the second negative conductive portion 422 are used to conduct the general electrical appliance reversely, so that the polarity of the first output pole 31 and the second output pole 32 can be reversed according to the conductive connection method of the conductive connector 4 to change the direction in which the current is conducted to the general electrical appliance.

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

[0050] Combination Figures 1 to 3 As shown, the second positive conductive portion 412 includes a first positive connection terminal 412a and a second positive connection terminal 412b, the first positive connection terminal 412a and the first positive conductive portion 411 are located on two opposite sides of the input positive electrode 21 along the first direction x in a one-to-one correspondence, and the second positive connection terminal 412b and the first negative conductive portion 421 are located on two opposite sides of the second output electrode 32 along the first direction x in a one-to-one correspondence.

[0051] In this embodiment, the second positive electrode conductive part 412 is a "Z-shaped structure", and the second positive electrode conductive part 412 includes a first positive electrode connection terminal 412a, a second positive electrode connection terminal 412b and an intermediate positive electrode connection terminal 412c, and the intermediate positive electrode connection terminal 412c is connected between the first positive electrode connection terminal 412a and the second positive electrode connection terminal 412b. When the conductive connector 4 is located at the reverse conduction position, the input positive electrode 21 is conductively connected to the first positive electrode connection terminal 412a, and the second output electrode 32 is conductively connected to the second positive electrode connection terminal 412b, so as to realize the reverse conduction general electrical appliance.

[0052] It should be understood that when the conductive connector 4 is located at the forward conduction position or the reverse conduction position, the relay is in the working state; when the conductive connector 4 is located at a position other than the forward conduction position and the reverse conduction position, the relay is in the non-working state. Therefore, when the relay is in the non-working state, the input positive electrode 21 is spaced apart from the first positive electrode connection terminal 412a and the first positive electrode conductive portion 411, and the second output electrode 32 is spaced apart from the second positive electrode connection terminal 412b and the first negative electrode conductive portion 421.

[0053] Combination Figures 1 to 3 As shown, the second negative electrode conductive portion 422 includes a first negative electrode connection terminal 422a and a second negative electrode connection terminal 422b. The first negative electrode connection terminal 422a and the first negative electrode conductive portion 421 are located at two opposite sides of the input negative electrode 22 in a one-to-one correspondence, and the second negative electrode connection terminal 422b and the first positive electrode conductive portion 411 are located at two opposite sides of the first output electrode 31 in a one-to-one correspondence.

[0054] In this embodiment, the second negative electrode conductive part 422 is a "Z-shaped structure", and the second negative electrode conductive part 422 includes a first negative electrode connection terminal 422a, a second negative electrode connection terminal 422b and an intermediate negative electrode connection terminal 422c, and 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 located at the reverse conduction 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, so as to realize the reverse conduction general electrical appliance.

[0055] It should be understood that when the relay is in a 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 conductive position and the reverse conductive 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 conductive position and the reverse conductive 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 conductive position and the reverse conductive 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] Combination 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 electrode conductive portion 421 is located between the input positive electrode 21 and the input negative electrode 22, and the first positive electrode conductive portion 411 is located on the side of the input positive electrode 21 away from the first negative electrode conductive portion 421.

[0059] Combination 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 conductive portion 411 is a "T-shaped structure", and the first positive conductive portion 411 includes a first positive conductive segment 411a and a connecting segment 411b that are connected to each other, and the connecting segment 411b is insulated and connected to the first positive connection terminal 412a and the second negative connection terminal 422b along the first direction x. The first positive conductive segment 411a is used to be conductively connected to the input positive electrode 21 and the first output electrode 31, and the connecting segment 411b is used to connect the first positive conductive segment 411a with the first positive connection terminal 412a and the second negative connection terminal 422b.

[0061] In this embodiment, combined with Figures 1 to 3 As shown, the box body 11 includes a first side plate 111 and a second side plate 112 which are arranged opposite to each other along a 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 portion 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 portion 421 can be conductively connected to the input electrode group 2 and the output electrode group 3 at the same time when the conductive connector 4 moves in a direction away from the first side plate 111, so as to realize forward conduction of the electrical appliance.

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

[0063] Combination Figure 1 and Figure 3 As shown, the relay further includes a first elastic component 5, which is connected between the first positive electrode conductive segment 411a and the first side plate 111 along the direction in which the conductive connector 4 switches between the forward conductive position and the reverse conductive position.

[0064] In this embodiment, when the conductive connector 4 is in the forward conduction position, the first positive pole conductive segment 411a is conductively connected to the input positive pole 21 and the first output pole 31, and the first elastic component 5 is stretched. The elastic restoring force of the first elastic component 5 enables the conductive connector 4 to switch from the forward conduction position to the non-conducting position, so as to facilitate the relay to switch from the working state to the non-working state.

[0065] At the same time, when the conductive connector 4 is in the reverse conduction position, the first positive electrode connection end 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 end 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 conduction position to the non-conducting position, so as to facilitate the relay to switch from the working state to the non-working 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] Combination 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 along the second direction y; wherein the first elastic member 61 is connected between the second positive electrode connection terminal 412b and the second side plate 112, and is located on the side of the second positive electrode 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 electrode connection terminal 422a and the second side plate 112, and is located on the side of the first negative electrode 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 located at the forward conducting position, the first negative electrode conductive portion 421 is conductively connected to the input negative electrode 22 and the second output electrode 32, the first elastic member 61 and the second elastic member 62 are compressed, and 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, so as to facilitate the relay to switch from the working state to the non-working state. In addition, after the first elastic member 61 and the second elastic member 62 are compressed, the first elastic member 61 can also prevent the second positive electrode connection end 412b from colliding with the second side plate 112, and the second elastic member 62 can also prevent the first negative electrode connection end 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 which are relatively arranged along the second direction y, the third elastic member 51 and the second elastic member 62 are relatively arranged along the first direction x, and the fourth elastic member 52 and the first elastic member 61 are relatively arranged 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 beneficial to ensure 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] Combination 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 electrode 21 and the input negative electrode 22 of the input electrode group 2 and the first output electrode 31 and the second output electrode 32 of the output electrode group 3 is changed, thereby adjusting the conduction direction of the electrical appliance.

[0076] Combination 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 this 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 drive unit 71 is energized and generates a magnetic field, and the second electromagnetic drive unit 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 drive unit 73 is energized and generates a magnetic field, and the first electromagnetic drive unit 71 is not energized; when the first wire segment 72, the second wire segment 74, and the common wire segment 75 are all disconnected, both the first electromagnetic drive unit 71 and the second electromagnetic drive unit 73 are not energized.

[0078] It should be understood that in the automatic control circuit, the relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, the current input to the drive mechanism 7 is different from the current input to the electrode group 2.

[0079] Furthermore, the relay also includes a magnetic transmission member 8, which is transmission-connected to the conductive connector 4. The magnetic transmission member 8 is located between the first electromagnetic drive part 71 and the second electromagnetic drive part 73, and can be displaced when the first electromagnetic drive part 71 or the second electromagnetic drive part 73 is energized to drive the conductive connector 4 to switch between the forward conduction position and the reverse conduction position.

[0080] In this embodiment, the magnetic transmission member 8 is insulated from the middle positive electrode connection end 412c and the middle negative electrode connection end 422c. The first positive electrode conductive part 411, the second positive electrode conductive part 412, the first negative electrode conductive part 421, the second negative electrode conductive part 422 and the magnetic transmission member 8 are a whole without relative movement. The magnetic transmission member 8 is driven to switch between the forward conduction position and the reverse conduction position by the movement of the first electromagnetic drive part 71 or the second electromagnetic drive part 73.

[0081] In this embodiment, combined with Figure 1 and Figure 5 As shown, 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 powered on 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 toward the direction close to the first electromagnetic driving part 71, and then the conductive connecting member 4 is driven by the magnetic transmission member 8 to move toward the direction close to the first side plate 111, so as to drive the conductive connecting member 4 to move to the reverse conduction position.

[0082] In this embodiment, combined with Figure 1 and Figure 4As shown, after the second electromagnetic drive part 73 is energized and generates a magnetic field, the second electromagnetic drive part 73 will attract the magnetic transmission part 8, causing the magnetic transmission part 8 to move toward the direction close to the second electromagnetic drive part 73, and then drive 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, only one of the first electromagnetic drive unit 71 and the second electromagnetic drive unit 73 is powered on, and both of them will not be powered on at the same time, so that the forward conduction and reverse conduction of the electrical appliance can only be realized selectively, so as to ensure the safety and reliability of the relay.

[0084] It should be understood that when the first electromagnetic drive part 71 and the second electromagnetic drive part 73 are not energized, the magnetic transmission part 8 is located between the first electromagnetic drive part 71 and the second electromagnetic drive part 73, and is spaced apart from the first electromagnetic drive part 71 and the second electromagnetic drive part 73 to ensure that the conductive connecting part 4 is not conductively connected to the input electrode group 2 and the output electrode group 3.

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

[0086] In this embodiment, the relay is not only simple in structure, but also can realize forward conduction and reverse conduction of the electrical appliance with fewer parts; it is also easy to produce, and the parts of the relay can be manufactured by common processing technology, which is conducive to reducing costs.

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

[0088] In other embodiments, the first positive conductive portion 411 can be a "single-line structure" and is insulated and connected to the first positive connection terminal 412a and the second negative connection terminal 422b through an insulating plate, that is, along the first direction x, the first positive conductive portion 411 is located on the side of the insulating plate close to the first side plate 111, and the first positive connection terminal 412a and the second negative connection terminal 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 portion 411 with the first positive connection terminal 412a and the second negative connection terminal 422b.

[0089] In addition, the first negative conductive portion 421 can also be insulated and connected to the second positive connection terminal 412b and the first negative connection terminal 422a through an insulating plate, that is, along the first direction x, the first negative conductive portion 421 is located on the side of the insulating plate close to the first side plate 111, and the second positive connection terminal 412b and the first negative connection terminal 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 portion 421 with the second positive connection terminal 412b and the first negative connection terminal 422a.

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

[0091] In other embodiments, the first positive conductive portion 411, the first positive connection terminal 412a and the second negative connection terminal 422b form a whole that is located between the opening of the input positive electrode 21 and the opening of the first output electrode 31, and is conductively connected to the input positive electrode 21 and the first output electrode 31 when the conductive connector 4 is located at the forward conduction position and the reverse conduction position; the first negative conductive portion 421, the second positive connection terminal 412b and the first negative connection terminal 422a form a whole that is located between the opening of the input negative electrode 22 and the opening of the second output electrode 32, and is conductively connected to the input negative electrode 22 and the second output electrode 32 when the conductive connector 4 is located at the forward conduction position and the reverse conduction position.

[0092] This embodiment also provides a vehicle, including a motor and the above-mentioned relay, wherein the motor is connected to the relay.

[0093] In this embodiment, the motor is conductively connected to the first output pole 31 and the second output pole 32 to achieve forward and reverse rotation of the motor.
