[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0081] This application proposes a deceleration component, Figures 1 to 8 These are some embodiments of the present application.

[0082] See also Figures 1 to 2 In some embodiments of the present application, the deceleration assembly includes a first deceleration member 2, which is suitable for being arranged on the movement path of the moving contact assembly 6. The first deceleration member 2 can contact the moving contact assembly 6 and generate friction when the moving contact assembly 6 moves, so as to reduce the speed of movement of the moving contact assembly 6.

[0083] In the technical solution of the present application, since the first speed reducer 2 is arranged on the movement path of the moving contact assembly 6, when the moving contact assembly 6 moves, the moving contact assembly 6 can contact the first speed reducer 2 and generate friction, so that the first speed reducer 2 hinders the movement of the moving contact assembly 6, that is, realizes the speed reduction function of the moving contact assembly 6, thereby avoiding the moving contact assembly 6 from colliding with other components in the switching device and generating loud noise when it moves quickly to the set position, so as to improve the user experience.

[0084] It should be noted that the set position mentioned above can be the fixed position when the moving contact assembly 6 is in contact with the static contact assembly 5, or it can be the fixed position after the moving contact assembly 6 is separated from the static contact assembly 5; there is no limitation here.

[0085] Among them, the first deceleration member 2 can be in contact with the moving contact assembly 6 and generate friction force throughout the entire movement stroke of the moving contact assembly 6, or it can be in contact with the moving contact assembly 6 and generate friction force during part of the movement stroke of the moving contact assembly 6; using the above two methods to reduce the speed of the moving contact assembly 6 is applicable to the technical solution of this application.

[0086] In some embodiments of the present application, when the first speed reducer 2 contacts the moving contact assembly 6, the first speed reducer 2 has a first position and a second position in its movement relative to the moving contact assembly 6; when the first speed reducer 2 is in the first position, the first speed reducer 2 has a first distance relative to the moving axis; when the first speed reducer is in the second position, the first speed reducer 2 has a second distance relative to the moving axis; wherein the first distance is smaller than the second distance; in this embodiment, the first speed reducer 2 will move when it contacts the moving contact assembly, and therefore has the above-mentioned first position and second position, thereby avoiding the first speed reducer 2 from interfering with the movement of the moving contact assembly 6, thereby causing the moving contact assembly 6 to be stopped and stationary before moving to the set position.

[0087] The above embodiment is explained. When the first speed reducer 2 is in the first position and the second position, it will contact the moving contact assembly 6; when the first speed reducer 2 is in the first position, the distance between the first speed reducer 2 and the moving axis is closer, so the first speed reducer 2 will abut the moving contact assembly 6 on the movement path of the moving contact assembly 6. If the first speed reducer 2 does not move, the setting of the first speed reducer 2 will cause the moving contact assembly 6 to be stopped and stationary. Therefore, when the moving contact assembly 6 abuts the first speed reducer 2, the first speed reducer 2 can gradually move from the first position to the second position, so that the first speed reducer 2 will not stop the movement of the moving contact assembly 6. At the same time, during the movement of the first speed reducer 2, the first speed reducer 2 and the moving contact assembly 6 will generate friction, thereby reducing the movement speed of the moving contact assembly 6.

[0088] The first position and the second position are explained by taking the movable contact assembly 6 moving in the first direction Z and the first deceleration member 2 moving in the second direction Y, and the second deceleration member 62 on the movable contact assembly 6 in contact and friction with the first deceleration member 2.

[0089] When the first speed reducer 2 is in the first position, part of the orthographic projection of the first speed reducer 2 in the first direction Z will fall on the second speed reducer 62. Therefore, when the first speed reducer 2 is in the first position, the first speed reducer 2 can stop the moving contact assembly 6 in the first direction Z. When the second speed reducer 62 contacts the first speed reducer 2 in the first position, the first speed reducer 2 moves in the second direction Y while maintaining contact with the second speed reducer 62, that is, moves from the first position to the second position, until the orthographic projection of the first speed reducer 2 in the first direction Z does not fall on the second speed reducer 62. At this time, the first speed reducer 2 will not interfere with the movement of the moving contact assembly 6 in the first direction Z.

[0090] In some embodiments of the present application, when the first speed reducer 2 is in the second position, the first speed reducer 2 and the second speed reducer 62 contact each other in the second direction Y.

[0091] It should be noted that the second deceleration member 62 in the above embodiment is only one embodiment of the moving contact assembly 6. The moving contact assembly 6 can have any component that cooperates with the first deceleration member 2 to achieve the above deceleration effect, and there is no limitation here.

[0092] The movement of the first deceleration member 2 from the first position to the second position can be driven by the abutting force of the movable contact assembly 6 or by an active driving device, which is not limited here.

[0093] In some embodiments of the present application, the deceleration assembly further includes a driving member, which is connected to the first deceleration member 2 to drive the first deceleration member 2 to move between the first position and the second position; that is, in this embodiment, the driving member can actively drive the first deceleration member 2 to move, thereby ensuring that the first deceleration member 2 can abut against the moving contact assembly 6 and reduce the movement speed of the moving contact assembly 6, while avoiding the first deceleration member 2 from blocking and interfering with the movement of the moving contact assembly 6.

[0094] See also Figure 3 In some embodiments of the present application, the deceleration assembly includes a first elastic member 3, which is connected to the first deceleration member 2 and can elastically expand and contract in the movement direction of the first deceleration member 2; in this embodiment, since the first elastic member 3 is connected to the first deceleration member 2, when the first elastic member 3 is elastically deformed, the position of the first deceleration member 2 can change, thereby enabling the first deceleration member 2 to move between the first position and the second position.

[0095] When the moving contact assembly 6 contacts the first deceleration member 2, the first elastic member 3 will contract or stretch, thereby changing the position of the first deceleration member 2 and moving from the first position to the second position to achieve the deceleration function of the moving contact assembly 6.

[0096] After the moving contact assembly 6 is separated from the first deceleration member 2 , the first elastic member 3 is reset, thereby driving the first deceleration member 2 to move from the second position to the first position.

[0097] It can be understood that since the movement of the moving contact assembly 6 is reciprocating, when the moving contact assembly 6 moves close to the static contact assembly 5 or moves away from the static contact assembly 5, the first elastic member 3 can drive the first deceleration member 2 to the first position and contact the moving contact assembly 6 to reduce the movement speed of the moving contact assembly 6.

[0098] In some embodiments of the present application, the first elastic member 3 is a spring.

[0099] In some embodiments of the present application, when the first deceleration member 2 is in the first position, the first elastic member 3 has a first compression amount; when the first deceleration member 2 is in the second position, the first elastic member 3 has a second compression amount; wherein the second compression amount is greater than the first compression amount; in this embodiment, when the first deceleration member 2 is not subjected to external force, the first elastic member 3 has a first compression amount, and when the moving contact assembly 6 abuts against the first deceleration member 2, the first elastic member 3 will be compressed, so that the first elastic member 3 has a second compression amount, and when the moving contact assembly 6 is separated from the first deceleration member 2, since the second compression amount is greater than the first compression amount, the first elastic member 3 will release energy, thereby causing the first elastic member 3 to return to the first compression amount, that is, driving the first deceleration member 2 to return to the first position.

[0100] In some embodiments of the present application, the first compression amount can be zero or greater than zero.

[0101] In some embodiments of the present application, the first speed reducer 2 includes a first surface 21, which is suitable for contacting the moving contact assembly 6 and generating friction when the moving contact assembly 6 moves; wherein, the first surface 21 is a curved surface; that is, in this embodiment, by setting the first surface 21 as a curved surface, the contact area between the moving contact assembly 6 and the first surface 21 is smaller, thereby avoiding excessive friction between the moving contact assembly 6 and the first speed reducer 2, which causes the moving contact assembly 6 to be relatively fixed between the first speed reducer 2, thereby affecting the movement of the moving contact assembly 6.

[0102] In some embodiments of the present application, when the first speed reducer 2 contacts the moving contact assembly (6), the first speed reducer 2 has a third distance relative to the moving axis of the moving contact assembly 6, and the third distance is a fixed value; that is, in this embodiment, the setting position of the first speed reducer 2 is fixed and will not interfere with the movement of the moving contact assembly 6, so as to reduce the movement speed of the moving contact assembly 6.

[0103] When the moving contact assembly 6 moves in the first direction Z and contacts the first speed reducer 2, the first speed reducer 2 is located on the side of the component of the moving contact assembly 6 that can contact the first speed reducer 2 in the second direction Y; at this time, friction can be generated between the first speed reducer 2 and the moving contact assembly 6 but will not stop the movement of the moving contact assembly 6 in the first direction Z, so as to reduce the movement speed of the moving contact assembly 6.

[0104] In some embodiments of the present application, the first speed reducer 2 includes a first surface 21, which is suitable for contacting the moving contact assembly 6 and generating friction when the moving contact assembly 6 moves; wherein the first surface 21 is a plane; in this embodiment, since the position of the first speed reducer 2 is fixed, the first surface 21 is set to be a plane to ensure that the moving contact assembly 6 can contact all parts of the first surface 21 of the moving contact assembly 6 when it moves, so that the first speed reducer 2 can play the function of reducing the movement speed of the moving contact assembly 6.

[0105] In some embodiments of the present application, the first deceleration member 2 has a third position and a fourth position relative to the moving axis of the moving contact assembly 6; when the first deceleration member 2 is in the third position, the first deceleration member 2 can contact the moving contact assembly 6 when the moving contact assembly 6 moves; when the first deceleration member 2 is in the fourth position, the first deceleration member 2 does not contact the moving contact assembly 6 when the moving contact assembly 6 moves; such a setting enables the first deceleration member 2 to release the speed limit setting for the moving contact assembly 6; when the switching device is in an abnormal state, the first deceleration member 2 is in the fourth position, so that the moving contact assembly 6 can quickly activate The movement of the moving contact assembly 6 is not restricted by the deceleration of the first deceleration member 2, so that the movement of the moving contact assembly 6 can quickly disconnect the power to the switching device to avoid damage to the switching device; when the switching device is in a normal state, the first deceleration member 2 is in the third position, and the moving contact assembly 6 can contact with the first deceleration member 2 to generate friction, so that the first deceleration member 2 hinders the movement of the moving contact assembly 6, that is, realizes the deceleration function of the moving contact assembly 6, thereby avoiding the moving contact assembly 6 from colliding with other components in the switching device when moving to the set position and generating loud noise, so as to improve the user experience.

[0106] It should be supplemented that the third position in the above embodiment can be any position between the first position and the second position, or can be the first position and the second position; this is not limited here.

[0107] In some embodiments of the present application, the deceleration assembly also includes a first drive assembly 4, which is arranged on one side of the first deceleration member 2, and the first drive assembly 4 is configured to drive the first deceleration member 2 to move from the third position to the fourth position to release the speed limit of the moving contact assembly 6 by the first deceleration member 2; in this embodiment, the first drive assembly 4 can actively drive the first deceleration member 2 to move from the third position to the fourth position when the switching device is in an abnormal state, so that the moving contact assembly 6 can move quickly and is not subject to the deceleration limit of the first deceleration member 2, so that the movement of the moving contact assembly 6 can quickly disconnect the power to the switching device to avoid damage to the switching device.

[0108] In some embodiments of the present application, when the switching device is in a short-circuit state, the first drive assembly 4 can actively drive the first reduction member 2 to move from the third position to the fourth position to release the speed limit of the moving contact assembly 6 by the first reduction member 2.

[0109] In some embodiments of the present application, the first drive component 4 includes a first magnetizer 41, which is arranged on one side of the first speed reducer 2 and can be magnetized; wherein, the first speed reducer 2 can be attracted by the magnetized first magnetizer 41 and move from the third position to the fourth position; in this embodiment, when the switching device is in a short-circuit state, a strong magnetic field will be formed inside the switching device, thereby magnetizing the first magnetizer 41. The magnetized first magnetizer 41 can attract the first speed reducer 2, so that the first speed reducer 2 moves from the third position to the fourth position under the action of magnetic force, thereby avoiding interference of the first speed reducer 2 with the rapid movement of the moving contact assembly 6.

[0110] It should be supplemented that the magnetic force generated by the first magnetic conductor 41 is greater than the elastic force of the first elastic member 3 , so that the first deceleration member 2 can overcome the pressure of the first elastic member 3 and move from the third position to the fourth position.

[0111] In some embodiments of the present application, the first drive assembly 4 includes a driving part and a driven part, the driving part is arranged on one side of the first speed reducer 2; the driven part is transmission-connected to the driving part and is connected to the first speed reducer 2; wherein, the driving part is used to drive the driven part to move, so that the first speed reducer 2 moves from the third position to the fourth position; that is, in this embodiment, through the active driving of the driven part by the driving part, the first speed reducer 2 can be moved from the third position to the fourth position, so as to release the speed limit of the moving contact assembly 6 by the first speed reducer 2.

[0112] The driving method of the driven part by the driving part is not limited and can be mechanical driving, magnetic driving, etc.

[0113] See also Figures 3 to 5In some embodiments of the present application, the driving part includes a first magnet 41, and the driven part includes a second magnet 42. The first magnet 41 is arranged on one side of the first deceleration member 2 and can be magnetized; the second magnet 42 is connected to the first deceleration member 2 and can be magnetized; wherein the magnetized first magnet 41 and the magnetized second magnet 42 can attract each other to drive the first deceleration member 2 to move from the third position to the fourth position; in this embodiment, when the switching device is in a short-circuit state, a strong magnetic field will be formed inside the switching device, thereby magnetizing the first magnet 41 and the second magnet 42, and the magnetized first magnet 41 and the magnetized second magnet 42 attract each other, so that the first deceleration member 2 moves from the third position to the fourth position under the action of magnetic force, thereby avoiding interference of the first deceleration member 2 with the rapid movement of the moving contact assembly 6.

[0114] It should be noted that the mutual attraction force between the first magnetic conductor 41 and the second magnetic conductor 42 is greater than the elastic force of the first elastic member 3, so that the first deceleration member 2 can overcome the pressure of the first deceleration member 2 and move from the first position to the second position.

[0115] In summary, the deceleration assembly can decelerate the moving contact assembly 6 during the normal on-off process of the switching device to reduce the impact force between the moving contact assembly 6 and other components in the switching device. When the switching device is in an abnormal state, the deceleration assembly can release the speed reduction limit on the moving contact assembly 6 to avoid affecting the disconnecting speed of the moving contact assembly 6 and ensure the disconnecting reliability of the switching device and the circuit connected to the switching device.

[0116] In some embodiments of the present application, the deceleration assembly also includes a mounting member 1, and the first magnet 41 is fixedly connected to the mounting member 1; the second magnet 42 is arranged on the side of the first deceleration member 2 close to the mounting member 1, and a portion of the second magnet 42 extends toward the first magnet 41 and is spaced from the first magnet 41; in this embodiment, by setting the first magnet 41 to be fixedly connected to the mounting member 1, when the magnetized first magnet 41 and the magnetized second magnet 42 attract each other, the first magnet 41 will not move and the second magnet 42 drives the first deceleration member 2 to move, thereby ensuring that the first deceleration member 2 can move from the first position to the second position.

[0117] It can be understood that if the first magnetic conductor 41 is movable, the second magnetic conductor 42 may drive the first deceleration member 2 to move to an intermediate position between the third position and the fourth position. At this time, the first deceleration member 2 may still abut the moving contact assembly 6 when the moving contact assembly 6 moves, causing the moving contact assembly 6 to be decelerated, thereby affecting the disconnecting speed of the moving contact assembly 6.

[0118] In some embodiments of the present application, the first magnetic conductor 41 and the second magnetic conductor 42 are configured to be arranged on one side of the static contact assembly 5; this arrangement is because when the switching device is short-circuited, a strong magnetic field will be formed around the static contact assembly 5. At this time, the first magnetic conductor 41 and the second magnetic conductor 42 located on one side of the static contact assembly 5 are easily magnetized and attracted to each other, thereby driving the first deceleration member 2 to move from the first position to the second position.

[0119] In some embodiments of the present application, the first deceleration member 2 is assembled to the mounting member 1 through the first elastic member 3 .

[0120] In some embodiments of the present application, the first speed reducer 2 includes a first surface 21, which is suitable for contacting the moving contact assembly 6 and generating friction when the moving contact assembly 6 moves; wherein the first surface 21 is a curved surface or a plane; in this embodiment, by setting the first surface 21 as a curved surface or a plane, the first surface 21 is flat and has no concave and convex parts, thereby avoiding the moving contact assembly 6 from getting stuck or stuck between the first speed reducer 2 when the moving contact assembly 6 abuts against the first speed reducer 2, thereby causing damage to the switching device.

[0121] The present application also proposes a switching device, comprising a static contact assembly 5, a moving contact assembly 6 and at least one deceleration assembly. The moving contact assembly 6 can move relative to the static contact assembly 5 to contact or separate from the static contact assembly 5; the moving contact assembly 6 can contact the first deceleration member 2 and generate friction when moving to reduce the movement speed; the deceleration assembly is as described above. Since the present switching device adopts all the technical solutions of all the above embodiments, it at least has the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0122] In this embodiment, during the movement of the moving contact assembly 6 toward or away from the static contact assembly 5, the moving contact assembly 6 generates friction due to contact with the first deceleration member 2 and hinders the movement of the moving contact assembly 6, thereby realizing the deceleration function of the moving contact assembly 6, thereby avoiding the moving contact assembly 6 from colliding with other components in the switch device and generating loud noise when moving to the set position, thereby improving the user experience.

[0123] It can be understood that when the moving contact assembly 6 is in contact with the static contact assembly 5 , the switch device is energized; when the moving contact assembly 6 is separated from the static contact assembly 5 , the switch device is de-energized.

[0124] There is no limitation on the movement mode of the movable contact assembly 6 . The movable contact assembly 6 may rotate around an axis or move linearly.

[0125] In some embodiments of the present application, the static contact assembly 5 is located on one side of the moving contact assembly 6 in the first direction Z; the moving contact assembly 6 can move along the first direction Z and contact or separate from the static contact assembly 5; that is, in this embodiment, the moving contact assembly 6 and the static contact assembly 5 are separated or matched in the first direction Z to achieve power-off or power-on of the switching device.

[0126] In some embodiments of the present application, when the moving contact assembly 6 moves toward or away from the static contact assembly 5 in the first direction Z, the moving contact assembly 6 can contact the first deceleration member 2 to reduce the movement speed; that is, in this embodiment, the first deceleration member 2 can decelerate the moving contact assembly 6 when the switching device is powered on or off, so as to avoid the moving contact assembly 6 from colliding with other components in the switching device when moving to the set position and generating loud noise, so as to improve the user experience.

[0127] In some embodiments of the present application, the moving contact assembly 6 is capable of moving between a fifth position and a sixth position; when the moving contact assembly 6 is in the fifth position, the moving contact assembly 6 is separated from the static contact assembly 5; when the moving contact assembly 6 is in the sixth position, the moving contact assembly 6 is in contact with the static contact assembly 5; wherein, the moving contact assembly 6 is separated from the first speed reducer 2 when in the fifth position and the sixth position; this arrangement is to avoid the moving contact assembly 6 still abutting against the first speed reducer 2 when in the fifth position and the sixth position, thereby easily causing metal fatigue of the first elastic member 3, and making it difficult for the first speed reducer 2 to reset when separated from the moving contact assembly 6.

[0128] In addition, when the first deceleration member 2 is in the first position, the second position, or the third position, it is located between the third position and the fourth position. For example, when the moving contact assembly 6 is driven by the electromagnetic member 81, the electromagnetic member 81 drives the moving contact assembly 6 in the first direction Z by magnetic force, and the moving contact assembly 6 accelerates. The first deceleration member 2 located between the third position and the fourth position can limit the speed of the moving contact assembly 6 during the accelerated movement, thereby reducing the speed of the moving contact assembly 6 when it moves to the set position. If the moving contact assembly 6 is speed-limited at the beginning of its movement, the moving contact assembly 6 can still move a longer distance after the speed limit, thereby increasing the speed of the moving contact assembly 6 when it moves to the set position, causing the moving contact assembly 6 to collide with other components in the switch device and generate a louder noise, thereby improving the user experience.

[0129] See also Figures 6 to 8In some embodiments of the present application, the moving contact assembly 6 includes a moving contact 61 and a second deceleration member 62. The moving contact 61 can move relative to the static contact assembly 5 to contact or separate from the static contact assembly 5; the second deceleration member 62 can contact the first deceleration member 2 and generate friction when the moving contact 61 moves; that is, in this embodiment, the abutment between the second deceleration member 62 and the first deceleration member 2 is utilized to realize the deceleration function of the moving contact assembly 6.

[0130] It can be understood that since the moving contact 61 needs to be energized, in order to avoid the moving contact 61 from abutting against the first deceleration member 2 and causing damage to the moving contact 61, a second deceleration member 62 connected to the moving contact 61 is provided in the above embodiment, and the abutment between the second deceleration member 62 and the first deceleration member 2 is utilized to achieve deceleration of the moving contact 61.

[0131] In some embodiments of the present application, the moving contact assembly 6 also includes a connecting member 63, which connects the moving contact 61 and the second deceleration member 62; such a configuration enables the second deceleration member 62 to move along with the moving contact 61, so that during the movement of the moving contact 61, the second deceleration member 62 is abutted against the first deceleration member 2 to achieve deceleration of the moving contact 61.

[0132] In some embodiments of the present application, the second speed reducer 62 includes a second surface 621, which can contact the first speed reducer 2 and generate friction when the moving contact 61 moves; wherein the second surface 621 is a curved surface or a flat surface; by setting the second surface 621 as a curved surface or a flat surface, the second surface 621 is flat and has no concave and convex parts, thereby avoiding the moving contact assembly 6 from getting stuck or stuck with the first speed reducer 2 when the moving contact assembly 6 abuts against the first speed reducer 2, thereby causing damage to the switching device.

[0133] In some embodiments of the present application, the switching device includes a shell 7, a portion of the static contact assembly 5 is located inside the shell 7, the other portion is located outside the shell 7, and the moving contact assembly 6 is movably arranged inside the shell 7; wherein, the deceleration assembly is located inside the shell 7, the mounting member 1 is fixedly connected to the shell 7 or a portion of the shell 7 forms the mounting member 1; that is, in this embodiment, a portion of the static contact assembly 5 is located outside the shell 7 and can be connected to an external circuit, and the other portion of the static contact assembly 5 and the moving contact assembly 6 are located inside the shell 7, thereby being protected by the shell 7 to ensure the safety of the switching device.

[0134] In addition, the first speed reducing member 2 is located in the housing 7 and is movable relative to the housing 7 .

[0135] In some embodiments of the present application, the static contact assembly 5 includes a connecting member 51 and a static contact 52. The connecting member 51 and the static contact 52 are connected to each other. The static contact 52 can contact or separate from the moving contact 61 to power on or off the switching device. A portion of the connecting member 51 extends to the outside of the shell 7 to connect to the external circuit.

[0136] In some embodiments of the present application, the switching device includes a second drive assembly 8, which is arranged on one side of the moving contact assembly 6 and is used to drive the moving contact assembly 6 to move so that the moving contact assembly 6 contacts or separates from the static contact assembly 5; that is, in this embodiment, the second drive assembly 8 is arranged to drive the moving contact assembly 6 to move in the first direction Z to realize the power on and off of the switching device.

[0137] In some embodiments of the present application, the second drive assembly 8 includes an electromagnetic component 81, the output end of the electromagnetic component 81 is connected to the static contact assembly 5 to drive the static contact assembly 5 to move through electromagnetic force; wherein, the electromagnetic component 81 includes a control part 811 and a movable part 812, and the control part 811 can generate different electromagnetic forces, so that the movable part 812 moves in the first direction Z, thereby driving the movable contact assembly 6 to move in the first direction Z and contact or separate from the static contact assembly 5.

[0138] In some embodiments of the present application, the movable portion 812 is confined within the control portion 811 to prevent the movable portion 812 from escaping from the control portion 811 .

[0139] In some embodiments of the present application, the control part 811 includes a yoke and a coil located inside the yoke; the movable part 812 includes a moving iron core, the coil can generate magnetic force to drive the moving iron core to move, and the yoke can enclose the magnetic lines generated by the coil inside the yoke to improve the efficiency of the electromagnetic component 81.

[0140] In some embodiments of the present application, the movable part 812 is limited in the control part 811, that is, the control part 811 will limit the movement range of the movable part 812, so that the movable part 812 will collide with the control part 811 when moving in the control part 811. The setting of the deceleration assembly can reduce the movement speed of the moving contact assembly 6 and the movable part 812, thereby reducing the impact force between the movable part 812 and the control part 811, so as to reduce the noise generated by the switching device.

[0141] Specifically, the deceleration assembly can reduce the impact force between the moving iron core and the yoke.

[0142] In some embodiments of the present application, the moving contact 61 is movably mounted on the connecting member 63 and is fixedly connected to the connecting member 63 via a second elastic member 64. This arrangement is due to the fact that the movement stroke of the movable part 812 in the first direction Z is greater than the gap between the moving contact 61 and the static contact 52 in the first direction Z. After the moving contact 61 and the static contact 52 contact each other, the movable part 812 still moves a certain distance in the first direction Z, so that the second elastic member 64 is compressed. The pressure provided by the second elastic member 64 can ensure the contact pressure between the moving contact 61 and the static contact 52, thereby ensuring the reliability of the electrical contact between the moving contact 61 and the static contact 52.

[0143] In some embodiments of the present application, the switch device further includes a control board 10 , which can output voltage to the electromagnetic member 81 to drive the movable contact assembly 6 to move.

[0144] The first direction Z is used as the up and down direction for explanation.

[0145] When the switching device switches from the power-off state to the power-on state, the drive control board 10 executes the instruction, thereby outputting the specified voltage to the electromagnetic component 81. The movable part 812 moves upward under the action of the electromagnetic force, driving the connecting member 63 fixedly connected to it, that is, driving the moving contact 61 elastically connected to the connecting member 63. Finally, the moving contact 61 contacts the static contact 52, so that the conductive circuit inside the switching device is connected.

[0146] The second speed reducer 62 is fixed on the connecting member 63 and moves therewith. In the initial stage of the movement of the movable part 812, the second speed reducer 62 is not in contact with the first speed reducer 2 and the speed reduction is not achieved. When the movable part 812 moves to approximately the middle position, it has a higher speed. At this time, the second speed reducer 62 begins to contact the first speed reducer 2 and the second speed reducer 62 squeezes the first speed reducer 2 to move from the first position to the second position, causing the movable part 812 to lose a certain amount of kinetic energy to achieve the purpose of speed reduction. When the movable part 812 leaves the middle position, the second speed reducer 62 is no longer in contact with the first speed reducer 2, the speed reduction is released, and the final action is completed.

[0147] Similarly, the movement direction of the movable portion 812 when the switch device switches from the power-on state to the power-off state is opposite to the movement direction of the movable portion 812 when the switch device switches from the power-off state to the power-on state, which will not be described in detail here.

[0148] In some embodiments of the present application, two deceleration assemblies are provided, and are respectively disposed on opposite sides of the connecting member 63 in the second direction Y.

[0149] In some embodiments of the present application, the first deceleration member 2 is movable in the first direction Z to switch between the first position and the second position.

[0150] The first direction Z and the second direction Y intersect each other, and the angle between each of the first direction ZX and the second direction YY is not limited and can be 80°, 85°, 90°, 95°, or 100°.

[0151] In some embodiments of the present application, the switching device also includes an arc extinguishing assembly 9, which is arranged on one side of the static contact assembly 5 and the moving contact assembly 6, and is used to extinguish the arc generated between the moving contact assembly 6 and the static contact assembly 5; wherein, the arc extinguishing assembly 9 can achieve an arc extinguishing effect by dividing and cooling the arc, thereby protecting the switching device.

[0152] In some embodiments of the present application, the arc extinguishing assembly 9 includes an arc extinguishing grid, which can extinguish the arc generated between the moving contact 61 and the static contact 52 and prevent the arc from flying out of the housing 7, and can also serve as a high-pressure gas discharge channel.
