[0055] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0056] Reference below Figure 1-Figure 12 The circuit switch 100 for a vehicle according to an embodiment of the present invention is described, and the circuit switch 100 for a vehicle can be applied to a vehicle.

[0057] Combination Figure 4-Figure 6As shown, the circuit switch 100 of a vehicle according to the utility model may mainly include: a wiring assembly 30 and a moving contact body 50, wherein the wiring assembly 30 may include a first static contact 311 and a second static contact 321, and the moving contact body 50 may include a first moving contact 511 and a second moving contact 521, and the moving contact body 50 has a first state and a second state. When the moving contact body 50 is in the first state, the first moving contact 511 is conductively connected to the first static contact 311, and the second moving contact 521 is conductively connected to the second static contact 321; when the moving contact body 50 is in the second state, the first moving contact 511 is disconnected from the first static contact 311, and the second moving contact 521 is disconnected from the second static contact 321; the sum of the distance between the first moving contact 511 and the first static contact 311 and the distance between the second moving contact 521 and the second static contact 321 is D1, and D1 satisfies the relationship: 16mm≤D1≤50mm.

[0058] Specifically, the wiring assembly 30 is used to connect to an external circuit by setting a first static contact 311 and a second static contact 321 on the wiring assembly 30, and setting a first moving contact 511 and a second moving contact 521 on the moving contact body 50, so that the moving contact body 50 has a first state and a second state relative to the wiring assembly 30, and can switch between the first state and the second state.

[0059] When the moving contact body 50 is in the first state, the first moving contact 511 contacts the first static contact 311, the first moving contact 511 is conductively connected to the first static contact 311, and the second moving contact 521 contacts the second static contact 321, the second moving contact 521 is conductively connected to the second static contact 321. At this time, the circuit switch 100 is in a closed state.

[0060] When the moving contact body 50 is in the second state, the first moving contact 511 is not in contact with the first static contact 311, the first moving contact 511 and the first static contact 311 are disconnected, and the second moving contact 521 and the second static contact 321 are not in contact, the second moving contact 521 and the second static contact 321 are disconnected. At this time, the circuit switch 100 is in the open state.

[0061] That is, by controlling the moving contact body 50 to rotate in the first direction or in the second direction, the moving contact body 50 can be switched between the first state and the second state, so that the circuit switch 100 can be switched between the closed state and the open state, and a breakpoint can be formed between the first static contact 311 and the first moving contact 511, and another breakpoint can be formed between the second static contact 321 and the second moving contact 521. Two breakpoints can be formed between the moving contact body 50 and the wiring assembly 30, which can be more conducive to arc extinguishing and improve the reliability and safety of the circuit switch 100.

[0062] Furthermore, the sum of the distance between the first moving contact 511 and the first static contact 311 and the distance between the second moving contact 521 and the second static contact 321 is the opening distance of the vehicle circuit switch 100. By taking the sum of the distance between the first moving contact 511 and the first static contact 311 and the distance between the second moving contact 521 and the second static contact 321 as D1, D1 satisfies the relationship: 16mm≤D1≤50mm.

[0063] In this embodiment, it is necessary to explain in detail that, under the conditions of the vehicle's calibrated instantaneous power consumption (for example: instantaneous power consumption ≤150w) and specific time requirements (for example: time length is less than 200 milliseconds), the reasonable opening distance range in which the moving contact main body 50 can be driven to execute state switching is: the sum of the distance between the first moving contact 511 and the first static contact 311 and the distance between the second moving contact 521 and the second static contact 321 is D1, and D1 satisfies the relationship: 16mm≤D1≤50mm, taking into account the cost as well as the reliability and safety of the circuit switch 100.

[0064] Specifically, the opening distance of the circuit switch 100 can be made more reasonable, which can not only avoid problems such as contact overheating and arc generation caused by insufficient opening distance, but also reduce the resistance of the circuit switch 100, improve the reliability of electrical connection, and reduce energy loss, thereby improving the reliability and safety of the circuit switch 100 and improving the working performance of the circuit switch 100.

[0065] Therefore, by setting the sum of the distance between the first moving contact 511 and the first static contact 311 and the distance between the second moving contact 521 and the second static contact 321 within a reasonable range, the opening distance of the circuit switch 100 can be made more reasonable, and the cost of the circuit switch 100, as well as the safety and reliability of the circuit switch 100 can be taken into account, thereby improving the comprehensive performance of the circuit switch 100.

[0066] Combination Figure 4 and Fig.12 As shown, the circuit switch 100 of the vehicle may further include: a first arc extinguishing assembly 70 and a second arc extinguishing assembly 80, the first arc extinguishing assembly 70 being used to extinguish an arc generated by a disconnection or conductive connection between the first static contact 311 and the first movable contact 511, and the second arc extinguishing assembly 80 being used to extinguish an arc generated by a disconnection or conductive connection between the second static contact 321 and the second movable contact 521.

[0067] Specifically, considering that the disconnection or conductive connection between the first static contact 311 and the first movable contact 511, as well as the disconnection or conductive connection between the second static contact 321 and the second movable contact 521 are often accompanied by the generation of electric arcs, the presence of electric arcs may cause the contacts to burn out, and in severe cases may cause a short circuit or even a safety accident. By providing a first arc extinguishing component 70 and a second arc extinguishing component 80, the first arc extinguishing component 70 extinguishes the arc generated by the disconnection or conductive connection between the first static contact 311 and the first movable contact 511, and the second arc extinguishing component 80 extinguishes the arc generated by the disconnection or conductive connection between the second static contact 321 and the second movable contact 521. An independent arc extinguishing component can be provided for each breakpoint, and the arc extinguishing effect is good, thereby improving the electrical safety of the circuit switch 100.

[0068] The first arc extinguishing assembly 70 and the second arc extinguishing assembly 80 may include: a plurality of grid sheets 81, a pressure-maintaining component hard sheet 82, a first soft sheet 83, an arc blowout prevention plate 84, and a second soft sheet 85. The plurality of grid sheets 81 are located in the arc extinguishing cavity 86, the first soft sheet 83 is arranged on one side of the pressure-maintaining component hard sheet 82, and the second soft sheet 85 is arranged on one side of the arc blowout prevention plate 84.

[0069] When an arc is generated, the arc can be introduced into the arc extinguishing cavity 86 and divided by the plurality of grids 81 to achieve arc extinguishing. In addition, when an arc is generated, the internal gas expands, the first soft sheet 83 and the second soft sheet 85 gradually bend from the initial vertical state, and the charged particles are sprayed to the arc spray prevention plate 84, and the charged particles are absorbed by the arc spray prevention plate 84, thereby preventing the charged particles from affecting or damaging other devices, thereby improving the safety of the circuit switch 100.

[0070] It should be noted that a permanent magnet 221 may be further provided in the first arc extinguishing assembly 70 and the second arc extinguishing assembly 80, and the arc may be elongated by the magnetic blowing force of the permanent magnet 221, so that the arc voltage may be increased, the arc may be extinguished, and the reliability of arc extinguishing may be further improved. In addition, the first arc extinguishing assembly 70 and the second arc extinguishing assembly 80 may also be other arc extinguishing devices, which are not specifically limited here.

[0071] Furthermore, the distance between the first moving contact 511 and the first static contact 311 is D2, the distance between the second moving contact 521 and the second static contact 321 is D3, and D2 and D3 satisfy the relationship: 8mm≤D2≤25mm, 8mm≤D3≤25mm. In this way, the distance between the first moving contact 511 and the first static contact 311 can be set within a reasonable range, and the distance between the second static contact 321 and the second moving contact 521 can be set within a reasonable range, so that the opening distance of the circuit switch 100 can be further optimized, making the opening distance of the circuit switch 100 more reasonable, and improving the safety and reliability of the circuit switch 100.

[0072] Combination Fig. 9 As shown, the moving contact body 50 can mainly include a first moving contact part 51, a second moving contact part 52 and a connecting part 53, the first moving contact point 511 is arranged on the first moving contact part 51, the second moving contact point 521 is arranged on the second moving contact part 52, the connecting part 53 is connected between the first moving contact part 51 and the second moving contact part 52, and the length of the moving contact body (50) is L, and L satisfies the relationship: 40mm≤L≤120mm.

[0073] In this embodiment, the length of the movable contact body 50 is set within a reasonable range, that is, 40 mm ≤ L ≤ 120 mm. This can not only prevent the movable contact body 50 from being too short and unable to match the opening range of the circuit switch 100, but also prevent the movable contact body 50 from being too long, resulting in the circuit switch 100 being too large. In this way, the circuit switch 100 can be miniaturized while ensuring that the opening range of the circuit switch 100 is within a reasonable range and the reliability of the circuit switch 100 is ensured.

[0074] Combination Figure 5 and Figure 6 As shown, the first moving contact 511 is directly opposite to the first stationary contact 311 , and the second moving contact 521 is directly opposite to the second stationary contact 321 .

[0075] Specifically, by arranging the first moving contact 511 and the first stationary contact 311 opposite each other, the contact between the first moving contact 511 and the first stationary contact 311 is a line contact, thereby increasing the contact area between the first moving contact 511 and the first stationary contact 311 and improving the stability of the conductive connection between the first moving contact 511 and the first stationary contact 311.

[0076] It should be noted that the first moving contact 511 may be an arc-shaped surface, and the first static contact 311 may be a plane. Therefore, the contact between the first moving contact 511 and the first static contact 311 is a line contact. The line contact can improve the connection stability.

[0077] Furthermore, by arranging the second moving contact 521 and the second stationary contact 321 opposite each other, the contact between the second moving contact 521 and the second stationary contact 321 is a line contact, thereby increasing the contact area between the second moving contact 521 and the second stationary contact 321 and improving the stability of the conductive connection between the second moving contact 521 and the second stationary contact 321.

[0078] Combination Fig. 9 and Fig.10As shown, the overall profile of the moving contact body 50 is shaped like an "S". Specifically, the overall profile of the moving contact body 50 can be shaped like an "S". Specifically, the first moving contact portion 51 and the second moving contact portion 52 can be bent relative to the connecting portion 53, and the first moving contact portion 51 and the second moving contact portion 52 extend in opposite directions. In this way, the structural design of the moving contact body 50 can be optimized, making the structure of the moving contact body 50 more stable and reliable, and the opening distance of the circuit switch 100 can be increased. In addition, the overall profile of the moving contact body 50 is shaped like an "S", which makes it easy for the elastic member 421 to be assembled and connected with the moving contact body 50. It should be noted that the overall profile of the moving contact body 50 can also be in other shapes, which are not specifically limited here.

[0079] Combination Figure 1-Figure 6 As shown, the wiring assembly 30 may include a first wiring member 31 and a second wiring member 32. The overall contours of the first wiring member 31 and the second wiring member 32 are both "hook"-shaped. The first static contact 311 is arranged on the first wiring member 31, and the second static contact 321 is arranged on the second wiring member 32.

[0080] Specifically, by setting the first static contact 311 on the first wiring member 31, the second static contact 321 on the second wiring member 32, and arranging the first wiring member 31 and the second wiring member 32 at an interval, the moving contact body 50 is set between the first wiring member 31 and the second wiring member 32, so that the positions of the first wiring member 31 and the first moving contact 511 can correspond, and the positions of the second wiring member 32 and the second moving contact 521 can correspond, so that when the moving contact body 50 rotates, the first moving contact 511 and the first static contact 311 can be connected, and the first moving contact 511 and the first static contact 311 can be connected, or the first moving contact 511 and the first static contact 311 can be disconnected, and the first moving contact 511 and the first static contact 311 can be disconnected.

[0081] Furthermore, the overall contours of the first wiring member 31 and the second wiring member 32 are both in a "hook" shape, which not only facilitates the external connection of the first wiring member 31 and the external connection of the second wiring member 32, thereby facilitating the setting of the circuit switch 100 in the circuit, but also facilitates the setting of the first static contact 311 and the second static contact 321, ensuring that the first moving contact 511 is opposite to the first static contact 311, and the second moving contact 521 is opposite to the second static contact 321, thereby improving the stability of the vehicle's circuit switch 100 in the closed state.

[0082] Combination Figure 5As shown, the circuit switch 100 of the vehicle may further include: a driving component 20 and a transmission component 40, wherein the first end of the transmission component 40 is connected to the driving component 20, and the second end of the transmission component 40 is connected to the moving contact body 50, so that the power of the driving component 20 can be transmitted to the moving contact body 50 through the transmission component 40, driving the moving contact body 50 to rotate in a first direction, or rotate in a second direction, thereby enabling the moving contact body 50 to switch between the first state and the second state.

[0083] Furthermore, the driving component 20 can obtain a control signal. When the driving component 20 obtains the control signal, it can be driven according to the control signal to drive the transmission component 40 to rotate, and then selectively drive the moving contact main body 50 to rotate in a first direction, so that the first moving contact 511 is conductively connected to the first static contact 311, and the second moving contact 521 is conductively connected to the second static contact 321, or drive the moving contact main body 50 to rotate in the second direction, so that the first moving contact 511 is disconnected from the first static contact 311, and the second moving contact 521 is disconnected from the second static contact 321.

[0084] In this way, by setting the drive component 20 and the transmission component 40, the circuit switch 100 can be actively opened and closed by only controlling the working state of the drive component 20, which can make the circuit switch 100 of the vehicle more intelligent and reliable.

[0085] Combination Fig.11 As shown, the driving assembly 20 may mainly include: a variable magnetic assembly 21 and a magnetic assembly 22. The magnetic assembly 22 is connected to the first end of the transmission assembly 40, and when the magnetic properties of the variable magnetic assembly 21 and the magnetic assembly 22 are the same, the magnetic assembly 22 moves in a first direction, and when the magnetic properties of the variable magnetic assembly 21 and the magnetic assembly 22 are opposite, the magnetic assembly 22 moves in a second direction.

[0086] Specifically, both the variable magnetic component 21 and the magnetic component 22 have magnetism. By arranging the variable magnetic component 21 and the magnetic component 22 at an interval, the variable magnetic component 21 and the magnetic component 22 will attract or repel each other.

[0087] When the variable magnetic component 21 and the magnetic component 22 have the same magnetism, the magnetic component 22 can move along the first direction under the action of the magnetic force. When the variable magnetic component 21 and the magnetic component 22 have opposite magnetism, the magnetic component 22 can move along the second direction under the action of the magnetism, thereby realizing the operation of the driving component 20.

[0088] Furthermore, the magnetic component 22 is connected to the first end of the transmission component 40 , so that when the driving component 20 is working, the magnetic component 22 can further drive the transmission component 40 to move, thereby achieving conductive connection or disconnection of the circuit switch 100 .

[0089] Combination Fig.11 As shown, the variable magnetic component 21 is a coil component. When the direction of the current flowing through the coil component changes, the magnetism of the coil component changes. In this way, the magnetic pole of the coil component can be controlled to change only by controlling the direction of the current of the coil component, so that the magnetism of the coil component is the same as or opposite to the magnetism of the magnetic component 22, so that the magnetic component 22 can be controlled to rotate in the first direction or in the second direction, making the structure of the driving component 20 simpler and more controllable.

[0090] Combination Fig.11 As shown, the coil assembly may mainly include: a coil 211, a coil frame (not shown in the figure), an iron core 212 and a yoke 213. The coil 211 is wound on the coil frame, the iron core 212 is accommodated in the coil frame, and there are two yokes 213 connected to both ends of the iron core 212, respectively, and the two yokes 213 are parallel to each other and arranged opposite to each other.

[0091] Specifically, a magnetic field is generated around the coil 211 when electricity is supplied, and the structural stability of the coil 211 can be ensured by winding the coil 211 around the outer periphery of the coil frame, and the iron core 212 is accommodated in the coil frame, and the two yokes 213 are respectively connected to the two ends of the iron core 212. Since the magnetic resistance of the iron core 212 is smaller than the magnetic resistance of the air, and the magnetic resistance of the yoke 213 is smaller than the magnetic resistance of the air, the magnetic lines of force generated by the energized coil 211 will be concentrated in the iron core 212 and the two yokes 213, and the two yokes 213 are parallel to and arranged opposite to each other, so that a strong magnetic field will exist between the ends of the two yokes 213 away from the iron core 212, and the direction of the magnetic field between the ends of the two yokes 213 away from the iron core 212 can be changed by only changing the direction of the current in the coil 211.

[0092] Combination Fig.11 As shown, the magnetic assembly 22 may mainly include: a permanent magnet 221 and two magnetic conductive parts 222 .

[0093] The permanent magnet 221 is connected between two magnetic conductive members 222 . The two magnetic conductive members 222 are located between ends of the two magnetic yokes 213 away from the iron core 212 . The two magnetic yokes 213 are selectively connected to the two magnetic conductive members 222 .

[0094] Specifically, by connecting the permanent magnet 221 between the two magnetic conductive parts 222, the two magnetic conductive parts 222 are magnetized by the permanent magnet 221, the magnetic conductive part 222 connected to the N pole of the permanent magnet 221 is an N pole, and the magnetic conductive part 222 connected to the S pole of the permanent magnet 221 is an S pole, and by locating the two magnetic conductive parts 222 between the ends of the two magnetic yokes 213 away from the iron core 212, the two magnetic conductive parts 222 can rotate under the action of electromagnetic attraction and electromagnetic repulsion, so that the rotation of the magnetic component 22 can be realized, and finally the two magnetic yokes 213 are selectively connected to the two magnetic conductive parts 222, and the magnetic lines of force of the magnetic field of the coil 211 are closed through the iron core 212, the two magnetic yokes 213 and the magnetic component 22, which can ensure the stability of the magnetic component 22 in the final state. Among them, the magnetic conductive part 222 includes but is not limited to magnetic steel.

[0095] Furthermore, as shown in the figure, the magnetic component 22 can also include: a wrapping piece, the wrapping piece is used to wrap the permanent magnet 221 and the two magnetic conductive parts 222, and the wrapping piece is provided with a first limiting portion 23 to cooperate with the transmission component 40 for transmission.

[0096] Specifically, by setting a wrapping piece, wrapping the wrapping piece around the outside of the permanent magnet 221 and the two magnetic conductive parts 222, the permanent magnet 221 and the two magnetic conductive parts 222 can be connected to prevent the two magnetic conductive parts 222 from separating from the permanent magnet 221 during the movement of the magnetic component 22, thereby improving the structural stability of the magnetic component 22 and ensuring the normal operation of the magnetic component 22 and even the driving component 20.

[0097] Furthermore, by providing a first limiting portion 23 on the wrapping member, the first limiting portion 23 can cooperate with the transmission assembly 40 in transmission, thereby realizing power transmission between the driving assembly 20 and the transmission assembly 40, thereby ensuring the normal operation of the circuit switch 100.

[0098] As described above, through the structural design of the driving component 20, on the one hand, it is only necessary to change the direction of the current passing through the coil 211 so that the magnetic field generated by the coil 211 component is reversed, so that the moving contact body 50 can be driven to rotate through the transmission component 40, thereby making the moving contact body 50 switch to the first state or the second state. On the other hand, when the direction of the current in the coil 211 is not changed, the action of the electromagnetic force can make the moving contact body 50 stably remain in the first state or the second state, thereby improving the stability and reliability of the vehicle circuit switch 100.

[0099] Combination Figure 4-Figure 10As shown, the transmission assembly 40 can mainly include: a rotating disk 41 and at least one elastic assembly 42. The moving contact main body 50 is rotatably arranged on the rotating disk 41. A second limiting portion 411 is arranged on the rotating disk 41. The second limiting portion 411 and the first limiting portion 23 are limitedly matched. The elastic assembly 42 is used to connect the rotating disk 41 and the moving contact main body 50.

[0100] Specifically, by setting the second limiting portion 411 on the rotating disk 41, the second limiting portion 411 and the first limiting portion 23 are limited and matched, so that when the magnetic component 22 rotates, it can drive the rotation of the rotating disk 41, that is, the transmission connection between the driving component 20 and the transmission component 40 can be realized.

[0101] Furthermore, by rotatably arranging the moving touch main body 50 on the rotating disk 41, and connecting at least one elastic component 42 between the moving touch main body 50 and the rotating disk 41, the rotating disk 41 can transmit power to the moving touch main body 50 through at least one elastic component 42, thereby driving the moving touch main body 50 to move, that is, the transmission connection between the transmission component 40 and the moving touch main body 50 can be realized.

[0102] Combination Figure 7 and Fig.11 As shown, one of the first limiting portion 23 and the second limiting portion 411 is a limiting protrusion, and the other is a limiting groove.

[0103] Specifically, one of the first limiting portion 23 and the second limiting portion 411 can be set as a limiting protrusion, and the other of the first limiting portion 23 and the second limiting portion 411 can be set as a limiting groove. In this way, the limiting protrusion only needs to be extended into the limiting groove, and the limiting protrusion can be limitedly matched with the limiting groove, thereby realizing the limiting cooperation between the first limiting portion 23 and the second limiting portion 411, which can not only improve the speed and accuracy of the limiting cooperation between the first limiting portion 23 and the second limiting portion 411, but also improve the stability and reliability of the limiting cooperation between the first limiting portion 23 and the second limiting portion 411, thereby improving the structural reliability of the circuit switch 100.

[0104] Furthermore, the rotation angle of the magnetic component 22 is β, the rotation angle of the connecting portion 53 is α, and α and β satisfy the relationship: β>α. Specifically, when the movable contact body 50 is switched from one of the first state and the second state to the other, the rotation angle of the rotating component is set to be greater than the rotation angle of the connecting portion 53, so that the large-angle rotation of the magnetic component 22 can be converted into a small-angle rotation of the movable contact body 50, thereby avoiding the rotation angle required by the movable contact body 50 being too large, resulting in an increase in the volume of the vehicle circuit switch 100, and ensuring the miniaturization of the vehicle circuit switch 100.

[0105] Further, β satisfies the relationship: 20°≤β≤25°. Specifically, by setting the rotation angle of the magnetic component 22 within a range when the movable contact body 50 is switched from one of the first state and the second state to the other, on the one hand, it can be avoided that the rotation angle of the magnetic component 22 is too small, resulting in a too small opening distance of the circuit switch 100 of the vehicle, and on the other hand, it can be avoided that the rotation angle of the magnetic component 22 is too large, resulting in an excessively large volume of the circuit switch 100 of the vehicle, so that the circuit switch 100 can be miniaturized while ensuring that the opening distance of the circuit switch 100 is within a reasonable range and the reliability of the circuit switch 100 is ensured.

[0106] Combination Fig. 9 As shown, a third limiting portion 412 is provided on the rotating disk 41, and the elastic component 42 may mainly include: a mounting shaft 422 and at least one elastic member 421, the mounting shaft 422 is connected to the rotating disk 41, one end of the elastic member 421 is connected and fixed to the mounting shaft 422, and the other end of the elastic member 421 is connected and fixed to the moving contact main body 50, when in the second state, the third limiting portion 412 abuts against the moving contact main body 50, and when in the first state, the third limiting portion 412 is disengaged from the abutment with the moving contact main body 50.

[0107] Specifically, by connecting and fixing the mounting shaft 422 to the rotating disk 41, connecting and fixing one end of the elastic member 421 to the mounting shaft 422, and connecting and fixing the other end of the elastic member 421 to the moving contact main body 50, the elastic member 421 can apply elastic force to the moving contact main body 50, thereby making the installation setting of the elastic component 42 more stable.

[0108] Furthermore, by providing a third limiting portion 412 on the rotating disk 41 , the third limiting portion 412 is located between the movable contact body 50 and the mounting shaft 422 , and under the elastic force of the elastic member 421 , the movable contact body 50 can selectively abut against the third limiting portion 412 .

[0109] Specifically, when the moving contact body 50 is in the first state, the third limiting portion 412 is disengaged from the moving contact body, and when the moving contact body 50 is in the second state, the third limiting portion 412 is in contact with the moving contact body 50, that is, the moving contact body 50 is simultaneously acted upon by the elastic member 421 and the third limiting portion 412, so that the position of the moving contact body 50 relative to the rotating disk 41 can be fixed and unique, thereby ensuring the stability of the moving contact body 50 in the second state, avoiding the moving contact body 50 from shaking and causing an electrical connection with the wiring assembly 30 that is not intended by the user, thereby improving the stability and reliability of the vehicle's circuit switch 100.

[0110] Further, when in the second state, the third limiting portion 412 abuts against the moving contact body 50, and the elastic member 421 is stretched by an amount X1. When in the first state, the third limiting portion 412 is disengaged from the abutment with the moving contact body 50, and the elastic member 421 is stretched by an amount X2, wherein X2>X1.

[0111] Specifically, when the movable contact body 50 switches from the second state to the first state, the rotating disk 41 rotates in the first direction. Since the rotation angle of the magnetic component 22 is greater than the rotation angle of the connecting portion 53, that is, the rotation angle of the rotating disk 41 is greater than the rotation angle of the movable contact body 50, before the first movable contact 511 contacts the first static contact 311 and the second movable contact 521 contacts the second static contact 321, the movable contact body 50 rotates synchronously with the rotating disk 41. When the first movable contact 511 contacts the first static contact 311, the movable contact body 50 rotates synchronously with the rotating disk 41. 11 contact, and after the second moving contact 521 contacts the second static contact 321, the rotating disk 41 continues to rotate, the wiring assembly 30 limits the continued rotation of the moving contact body 50, the elastic member 421 is stretched, and the stretching amount of the elastic member 421 gradually increases from X1 to X2, so that the elastic assembly 42 can store elastic potential energy, and the elastic potential energy stored in the elastic assembly 42 can be converted into pressure between the first moving contact 511 and the first static contact 311, as well as pressure between the second moving contact 521 and the second static contact 321.

[0112] In this way, the stability of the circuit switch 100 in the closed state can be improved, and even if any one or more of the first moving contact 511, the first stationary contact 311, the second moving contact 521 and the second stationary contact 321 are worn, stable and reliable contact between the first moving contact 511 and the first stationary contact 311, as well as stable and reliable contact between the second moving contact 521 and the second stationary contact 321 can be guaranteed, thereby improving the reliability of the circuit switch 100.

[0113] Further, when the moving contact body 50 switches from the first state to the second state, before the first moving contact 511 and the first static contact 311 are disconnected, and the second moving contact 521 and the second static contact 321 are disconnected, the moving contact body 50 does not move, and the rotating disk 41 is not only driven by the driving force of the driving component 20, but also by the elastic driving force of the elastic component 42, so that the rotating disk 41 can rotate faster, until the rotating disk 41 can drive the moving contact body 50 to rotate synchronously, so that the first moving contact 511 and the first static contact 311 are disconnected, and the second moving contact 521 and the second static contact 321 are disconnected, after which the elastic driving force of the elastic component 42 on the rotating disk 41 is withdrawn, and the rotating disk 41 is only driven by the driving force of the driving component 20, and the moving contact body 50 is finally in the second state.

[0114] In this way, the opening force of the circuit switch 100 can be increased, the opening response speed of the circuit switch 100 can be increased, and the working performance of the circuit switch 100 can be further improved.

[0115] In a specific embodiment of the present invention, Figure 7-10 As shown, there are two elastic components 42, and the two elastic components 42 correspond to the first moving contact part 51 and the second moving contact part 52 respectively, and the third limiting part 412 is also set to two, and the two third limiting parts 412 correspond to the two elastic components 42. Each elastic component 42 can mainly include: a mounting shaft 422 and two elastic members 421, so that the two elastic members 421 in one of the two elastic components 42 are respectively located on one side of the first moving contact part 51 close to the rotating disk 41 and the side away from the rotating disk 41, and selectively make the corresponding third limiting part 412 and The first moving contact part 51 is abutted against each other, and the two elastic parts 421 in the other of the two elastic components 42 are respectively located on one side of the second moving contact part 52 close to the rotating disk 41 and the side away from the rotating disk 41, and the corresponding third limiting part 412 is selectively abutted against the second moving contact part 52, so that the force on the moving contact main body 50 can be more uniform and reasonable, and the stability of the moving contact main body 50 in the first state and the second state can be improved, and the stability of the moving contact main body 50 in the process of switching from one of the first state and the second state to the other can be improved.

[0116] Combination Figure 4 and Figure 5 As shown, the circuit switch 100 of the vehicle further includes: a collection component 60, which is used to collect electrical parameters representing the circuit where the circuit switch 100 is located, and the electrical parameters are used to confirm the control signal.

[0117] Specifically, when the circuit switch 100 of the vehicle turns on the circuit, the connection state, current size, temperature and other electrical parameters of the circuit switch 100 can characterize the state of the circuit where the circuit switch 100 is located. By setting the acquisition component 60, the acquisition component 60 can collect electrical parameters that characterize the circuit where the circuit switch 100 is located, and confirm the control signal based on the acquired electrical parameters, thereby actively detecting the circuit where the circuit switch 100 is located, making the circuit switch 100 of the vehicle more intelligent and reliable.

[0118] Combination Figure 4 and Figure 5 As shown, the acquisition component 60 may include one of a current detection component 61, a temperature detection component 62, and a switch state detection component, or a combination thereof.

[0119] Specifically, the acquisition component 60 may include a current detection component 61, which can detect the current of the circuit where the circuit switch 100 is located. The current detection component 61 can send different control signals according to whether the current is within the normal range to control the operation of the drive component 20, so that when the circuit is working normally, the circuit switch 100 maintains its original state, and when a short circuit or current overload occurs in the circuit, the circuit switch 100 is switched to the open state, so that short-circuit protection and overload protection of the circuit where the circuit switch 100 is located can be actively realized, and the short-circuit protection and overload protection are more intelligent and reliable. In addition, in the case of a short-circuit fault, the circuit switch 100 can also be reused, which can increase the number of current protection times and improve the probability that the vehicle can drive to the maintenance point by itself after the fault.

[0120] Furthermore, the acquisition component 60 may also include a temperature detection component 62, which can detect the temperature near the first static contact 311 and / or the second static contact 321. In this way, when overtemperature occurs near the first static contact 311 and / or the second static contact 321, the temperature detection component 62 can send different control signals according to whether the temperature is within the normal range to control the operation of the drive component 20, so that when the temperature is within the normal range, the circuit switch 100 maintains its original state, and when overtemperature occurs, the circuit switch 100 is switched to the open state to prevent the circuit switch 100 from continuing to operate in the overtemperature state, thereby ensuring the working performance and service life of the circuit switch 100, thereby actively realizing overtemperature protection for the circuit switch 100, and the overtemperature protection is more intelligent and reliable.

[0121] Furthermore, the acquisition component 60 may also include: a switch state detection component, which can detect whether the circuit switch 100 is in an open state or a closed state, and send different control signals according to the different states of the circuit switch 100, so that the driving component 20 can receive the control signal and selectively drive the moving contact body 50 to rotate or keep the current state unchanged according to whether the current state of the circuit switch 100 is consistent with the state to be switched to.

[0122] Combination Fig.11 As shown, the circuit switch 100 of the vehicle may further include: a controller 90, and the controller 90 is respectively connected to the acquisition component 60 and the drive component 20. Specifically, by setting the controller 90 and connecting the controller 90 to the acquisition component 60 and the drive component 20, the controller 90 can obtain the electrical parameters of the acquisition component 60, confirm the control signal according to the obtained electrical parameters, and then send the control signal to the drive component 20 to control the operation of the drive component 20, so that the intelligent control of the circuit switch 100 of the vehicle can be realized through the controller 90, and the circuit switch 100 of the vehicle can be made more intelligent and reliable.

[0123] Among them, the controller 90 can mainly include an acquisition unit, a communication unit and a drive unit. The acquisition unit is electrically connected to the communication unit and the drive unit respectively, the acquisition unit is electrically connected to the acquisition component 60, and the drive unit is electrically connected to the drive component 20. The communication unit is used to be electrically connected to the vehicle's on-board host computer. In this way, the acquisition unit can obtain the electrical parameters of the acquisition component 60, and after collecting the corresponding electrical parameters, it can selectively transmit the signal to the drive unit. The drive unit controls the operation of the drive component 20, thereby realizing the control of the opening or closing of the circuit switch 100, or transmitting the signal to the communication unit, and then transmitting it to the vehicle's on-board host computer through the communication unit, thereby making the circuit switch 100 more intelligent and reliable.

[0124] In addition, the controller 90 is also provided with a storage unit, which can record the number of short circuits, fault information, etc. When the number of short circuits reaches the set strategy warning value, it will be actively reported to the vehicle-mounted host computer through the communication unit to remind the user to repair it in time.

[0125] Specifically, the controller 90 can be configured to: generate a disconnect control signal when the electrical parameters obtained by the acquisition component 60 indicate an abnormality, and the drive component 20 can be configured to drive according to the received disconnect control signal, so that the first moving contact 511 is disconnected from the first static contact 311, and the second moving contact 521 is disconnected from the second static contact 321. In this way, when the relevant electrical parameters of the vehicle's circuit switch 100 are abnormal, the controller 90 can generate a disconnect control signal accordingly and transmit it to the drive component 20, control the movement of the drive component 20, so that the drive component 20 drives the moving contact body 50 to switch to the second state, and switches the circuit switch 100 to the open state, so as to prevent the circuit from continuing to operate in an abnormal state and prevent damage to other electronic components in the circuit.

[0126] Furthermore, the controller 90 can also be configured to: generate a reset control signal when the electrical parameters obtained by the acquisition component 60 indicate that the disconnection is resettable, and the drive component 20 can also be configured to drive according to the received reset control signal, so that the first moving contact 511 is conductively connected to the first static contact 311, and the second moving contact 521 is conductively connected to the second static contact 321. In this way, when the relevant electrical parameters of the vehicle's circuit switch 100 are disconnected and resettable, the controller 90 can generate a reset control signal accordingly and transmit it to the drive component 20, control the movement of the drive component 20, so that the drive component 20 drives the moving contact body 50 to switch to the first state, so that the circuit switch 100 switches to the closed state, and the circuit switch 100 turns on the circuit.

[0127] Combination Figure 1-Figure 5As shown, the circuit switch 100 of the vehicle is also provided with a housing 10, and the wiring assembly 30, the moving contact body 50, the drive assembly 20, the transmission assembly 40, the collection assembly 60, the first arc extinguishing assembly 70, the second arc extinguishing assembly 80 and the controller 90 are all arranged in the housing 10, so that the housing 10 can play a protective role for the wiring assembly 30, the moving contact body 50, the drive assembly 20, the transmission assembly 40, the collection assembly 60, the first arc extinguishing assembly 70, the second arc extinguishing assembly 80 and the controller 90, so as to prevent the wiring assembly 30, the moving contact body 50, the drive assembly 20, the transmission assembly 40, the collection assembly 60, the first arc extinguishing assembly 70, the second arc extinguishing assembly 80 and the controller 90 from being eroded by foreign objects or impacted by external forces, thereby improving the structural reliability of the circuit switch 100. Among them, the housing 10 is also provided with an air outlet 12, and when the internal gas expands, the expanded gas can be discharged through the air outlet 12 provided on the housing 10.

[0128] Furthermore, a partition 11 is provided in the housing 10, and the partition 11 divides the internal space of the housing 10 into a first cavity 101 and a second cavity 102. The wiring assembly 30 and the moving contact body 50 are both provided in the first cavity 101, and the drive assembly 20 and the controller 90 are provided in the second cavity 102, so that the drive assembly 20 and the controller 90 can be separated from other components, and the drive assembly 20 and the controller 90 can be prevented from being affected by electric arcs or charged particles and unable to work normally. Among them, a wire hole 111 can be provided on the partition 11, and the signal transmission wire of the current detection component 61 and the wiring harness of the temperature detection component 62 can pass through the wire hole 111 to be electrically connected to the controller 90.

[0129] The vehicle according to the utility model may include: the above-mentioned vehicle circuit switch 100. Specifically, by applying the vehicle circuit switch 100 to the vehicle, the circuit switch 100 can realize the control and protection of the circuit in which it is located, and the circuit switch 100 can be reused, which can not only make the vehicle more intelligent and controllable, but also reduce the after-sales maintenance cost, thereby improving the user experience and enhancing the product competitiveness of the vehicle.
