[0041] Among them, the length direction of the cavity 13 can be extended in the left-right direction, the liquid inlet 14 can be opened at the top of the valve body 1, the liquid outlet 15 can be opened at the bottom of the valve body 1, the right end of the first movable member 2 can be assembled on the left end of the cavity 13, the left end of the second movable member 3 can be assembled on the right end of the cavity 13, and the driving component 4 can be connected to the left end of the first movable member 2 and the right end of the second movable member 3.
[0042] Specifically, the first movable member 2 and the second movable member 3 can be moved closer to each other through the driving component 4, so that the cavity 13 connected between the liquid inlet 14 and the liquid outlet 15 is blocked, so that the brake fluid cannot flow from the liquid inlet 14 to the liquid outlet 15, the valve is closed, the brake fluid is cut off, and there is no braking effect; or the first movable member 2 and the second movable member 3 can be moved away from each other through the driving component 4, so that the cavity 13 connected between the liquid inlet 14 and the liquid outlet 15 is connected, so that the brake fluid flows from the liquid inlet 14 to the liquid outlet 15, the valve is opened, the brake fluid flows, and the braking effect is started; the action execution of the switch valve is realized, and the first movable member 2 and the second movable member 3 move simultaneously and their displacement is small, so as to improve the response speed of the switch valve to adapt to the driver's real-time and expected brake pedal feel requirements when stepping on the brake pedal; it has the characteristics of simple structure, short fluid path stroke, small pressure loss, small displacement during action, and fast response speed.
[0043] In some embodiments, Figure 1As shown, the first movable member 2 may include a first armature 21, one end of which passes through the cavity 13 and is slidably connected to the valve body 1; the second movable member 3 includes a second armature 31, one end of which passes through the cavity 13 and is slidably connected to the valve body 1; the driving component 4 includes: a first electromagnet component 41, the first electromagnet component 41 is connected to the first armature 21; a second electromagnet component 42, the second electromagnet component 42 is connected to the second armature 31; when the first electromagnet component 41 and the second electromagnet component 42 are at a high level, the first electromagnet component 41 and the second electromagnet component 42 drive the first armature 21 and the second armature 31 to move away from each other; when the first electromagnet component 41 and the second electromagnet component 42 are at a low level, the first electromagnet component 41 and the second electromagnet component 42 drive the first armature 21 and the second armature 31 to fit together.
[0044] Among them, the first electromagnet assembly 41 is connected to the first armature 21, and the second electromagnet assembly 42 is connected to the second armature 31. The first electromagnet assembly 41 and the second electromagnet assembly 42 can be driven by the same power supply, or they can be driven by a separate power supply respectively; when the first electromagnet assembly 41 and the second electromagnet assembly 42 are passed through a high level, the first electromagnet assembly 41 attracts the first armature 21 to move left, and the second electromagnet assembly 42 attracts the second armature 31 to move right, so that the first armature 21 and the second armature 31 are separated from each other, and the liquid inlet 14, the cavity 13 and the liquid outlet 15 are connected, and the brake fluid flows; when the first electromagnet assembly 41 and the second electromagnet assembly 42 are passed through a low level, the first electromagnet assembly 41 drives the first armature 21 to move right and reset, and the second electromagnet assembly 42 drives the second armature 31 to move left and reset, so that the first armature 21 and the second armature 31 fit each other, and the cavity 13 connected by the liquid inlet 14 and the liquid outlet 15 is blocked, and the brake fluid is cut off.
[0045] In some embodiments, Figure 1 As shown, one end of the first armature 21 is attached to the two opposite inner walls of the cavity 13, and its end has a first groove 22, and the side wall of the first groove 22 is provided with a first through hole 23; when the first armature 21 and the second armature 31 are away from each other, the first through hole 23 can be connected with the liquid inlet 14, so that the brake fluid flows to the liquid outlet 15 through the first through hole 23, the first groove 22 and the cavity 13 in sequence; when the first armature 21 and the second armature 31 are attached to each other, one end of the second armature 31 is blocked in the notch of the first groove 22, so that the first through hole 23 and the liquid inlet 14 are dislocated and interrupted.
[0046] Among them, the right end of the first armature 21 is attached to the upper and lower inner walls of the cavity 13, and when the first through hole 23 is moved to the left and connected coaxially with the liquid inlet 14 (it can also be non-coaxially connected), the brake fluid can flow into the first groove 22, or when it is moved to the right and interrupted by the liquid inlet 14, the brake fluid cannot flow into the cavity 13 or the first groove 22, so that when the first armature 21 and the valve body 1 are slidingly assembled, the sealing ring 16 component can be omitted, thereby saving material costs.
[0047] In some embodiments, Figure 1 As shown, a blocking block 32 is fixed to one end of the second armature 31, and the blocking block 32 is conical or truncated cone-shaped at one end close to the first armature 21; when the first armature 21 and the second armature 31 are in contact with each other, one end of the second armature 31 at least partially moves into the first groove 22 to block the notch of the first groove 22.
[0048] Among them, a sealing block 32 is fixed to the left end of the second armature 31. The left end of the sealing block 32 can be in a truncated cone shape or a conical shape, which can be moved into the first groove 22 and sealed with one end of the first armature 21. It has good sealing effect and improves the problem of traditional planar sealing and high requirements on the flatness of the sealing block 32 and the first armature 21.
[0049] In some embodiments, Figure 2 As shown, a tapered groove 24 is formed on the inner side wall of the notch of the first groove 22 , and the tapered groove 24 is matched with the blocking block 32 .
[0050] The right end notch of the first groove 22 may also be provided in a conical groove 24 adapted to the blocking block 32 , so as to further improve the sealing effect between the first armature 21 and the blocking block 32 .
[0051] Of course, in some embodiments, the first armature 21 and the second armature 31 may also be sealed by plane end surface contact.
[0052] In some embodiments, Figure 1 As shown, the valve body 1 is provided with a second through hole, a sealing ring 16 is installed in the second through hole, the second armature 31 passes through the sealing ring 16, and is slidably connected with the valve body 1. The sealing ring 16 can improve the brake fluid leakage problem between the second armature 31 and the valve body 1.
[0053] In some embodiments, Figure 1As shown, the first electromagnet assembly 41 may include: a first static iron core 411, the first static iron core 411 has a second groove 412, and a first electromagnetic coil 413 is arranged inside the second groove 412; the inner bottom wall of the second groove 412 is provided with a first protrusion 414, and the outer wall of the first protrusion 414 is sleeved with a first elastic member 415, one end of the first elastic member 415 passes through the interior of the first electromagnetic coil 413 and is fixed to the other end of the first armature 21.
[0054] Among them, the first protrusion can be cylindrical, the second groove 412 of the first static iron core 411 can face the first armature 21, and the first electromagnetic coil 413 is located in the second groove 412. When the first electromagnetic coil 413 is passed to a high level, the first static iron core 411 generates a magnetic attraction to attract the first armature 21 to move left, thereby realizing the braking action. After the braking action is completed, when the first electromagnetic coil 413 is passed to a low level, the first armature 21 is reset under the elasticity of the first elastic member 415, thereby completing the action of moving the first armature 21 left and right.
[0055] In some embodiments, the first elastic member 415 may be a spring or a spring telescopic rod.
[0056] Of course, if Figure 1 As shown, the second electromagnet assembly 42 may also include a second static iron core 421 , a third groove 422 , a second electromagnetic coil 423 , a second protrusion 424 and a second elastic member 425 ; its structural arrangement is consistent with that of the first electromagnet assembly 41 .
[0057] Of course, the first elastic member 415 of the first electromagnet assembly 41 and the first elastic member 415 of the second electromagnet assembly 42 can be omitted, and an elastic member is connected between the inner bottom wall of the first groove 22 of the first armature 21 and the blocking block 32. When a low level is passed, the elastic force of the elastic member pulls the first armature 21 and the second armature 31 to fit together, thereby further saving material costs.
[0058] Of course, in some embodiments, the first electromagnet assembly 41 and the second electromagnet assembly 42 can also be replaced by a hydraulic drive mode, both of which are connected to the two ends of the cavity 13 by pipelines to achieve the action of the first armature 21 and the second armature 31 approaching or moving away from each other.

[0060] Among them, the inner diameter of the right end of the cavity 13 is larger than the inner diameter of the left end thereof. When the first armature 21 and the second armature 31 perform actions at the same time, the impact of the brake fluid pressure fluctuation on the inside of the valve body 1 can be reduced, and the force of the brake fluid overflowing and impacting the second chamber 132 when the blocking block 32 blocks the first groove 22 can be improved, thereby ensuring the service life of the valve body 1.
[0061] In some embodiments, Figure 1 As shown, the valve body 1 includes: a valve cover 11; a valve seat 12, the cavity 13 is opened in the valve seat 12, and the liquid inlet 14 and the liquid outlet 15 are opened on opposite sides of the valve seat 12, and the valve seat 12 is fixed to the valve cover 11 by welding.
