DETAILED DESCRIPTION

[0063] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0064] The present disclosure provides a switch. Figure 1 For an exploded view of the switch, see Figure 1 The switch includes a panel 10, a housing 20, a switch assembly 30 and a lever assembly 40.

[0065] Figure 2 This is a cross-sectional view of the switch, combined with Figure 2In this embodiment, the panel 10 is disposed on one side of the housing 20, and the side of the panel 10 facing the housing 20 has an inner recess 110, and the inner recess 110 has an outer through hole 120. The switch assembly 30 is located in the housing 20 and can swing relative to the housing 20. The lever assembly 40 is inserted in the outer through hole 120, and at least part of the outer wall of the lever assembly 40 is accommodated in the inner recess 110 to cover the outer through hole 120. The lever assembly 40 is pivotally connected to the housing 20, the lever assembly 40 penetrates the housing 20 and contacts the switch assembly 30, and the lever assembly 40 is configured to swing the switch assembly 30 to turn the switch on or off.

[0066] When the switch provided by the embodiment of the present disclosure is used to turn the electrical system on and off, the user toggles the lever assembly 40 to swing the lever assembly 40 relative to the housing 20, thereby causing the lever assembly 40 to drive the on-off assembly 30 to swing together. During the swinging of the on-off assembly 30, the switch can be turned on or off, thereby turning the electrical system on and off.

[0067] When the switch is turned on or off, the arc light generated at the switch assembly 30 will be transmitted toward the panel 10 through the housing 20. Since the outer through hole 120 for accommodating the lever assembly 40 is located in the inner recess 110, and at least part of the outer wall of the lever assembly 40 is accommodated in the inner recess 110, the lever assembly 40 can shield the outer through hole 120, effectively reducing the gap between the panel 10 and the lever assembly 40. In this way, the arc light at the outer through hole 120 can be effectively shielded, preventing the arc light from flashing out of the switch.

[0068] In some examples, the switch assembly 30 includes a seesaw and a terminal, the two ends of the seesaw have silver dots, and the swing axis of the seesaw is located between the two ends of the seesaw. With such a design, the switch is a seesaw switch. The silver dots at the two ends of the seesaw serve as moving contacts, and the copper sheet connected to the terminal serves as a static contact.

[0069] In other examples, the switch assembly 30 includes a pendulum and a terminal, one end of the pendulum has a silver dot, and the swing axis of the pendulum is located at the other end of the pendulum. In this design, the switch is a pendulum switch. The silver dot at the end of the pendulum serves as a moving contact, and the copper sheet connected to the terminal serves as a static contact.

[0070] The main path for the arc light generated at the switch assembly 30 to be transmitted outward is the outer through hole 120. Therefore, in this embodiment, a light shielding treatment is performed on the outer through hole 120 to play a role in shielding the arc light from flashing out.

[0071] Figure 3 This is a schematic diagram of the assembly between the lever assembly and the panel, combined with Figure 3In this embodiment, the orthographic projection of the lever assembly 40 on the plane where the external through hole 120 is located covers the external through hole 120 .

[0072] In the above implementation, the positional relationship between the outer through hole 120 and the lever assembly 40 is designed in this way, so as to ensure the shielding effect of the lever assembly 40 on the outer through hole 120. In addition, since the orthographic projection of the lever assembly 40 is guaranteed to cover the outer through hole 120, even if the lever assembly 40 swings, the lever assembly 40 can always play the role of shielding the outer through hole 120.

[0073] Continue to see Figure 3 As can be seen from the foregoing, since the outer through hole 120 for accommodating the lever assembly 40 is located in the inner recess 110, and at least part of the outer wall of the lever assembly 40 is accommodated in the inner recess 110, the lever assembly 40 can shield the outer through hole 120, effectively reducing the gap between the panel 10 and the lever assembly 40. In this way, the arc light can be blocked from flashing out of the gap between the panel 10 and the lever assembly 40. In addition, it can also eliminate safety hazards and improve the reliability of the switch.

[0074] It is worth noting that the inner recess 110 is an inner recess, and its inner recess direction is away from the housing 20 , so as to serve to accommodate the lever assembly 40 .

[0075] Continue to see Figure 3 In this embodiment, at least a portion of the outer wall of the lever assembly 40 is a first curved surface 410, and the inner wall of the inner recess 110 is a second curved surface 111. The first curved surface 410 and the second curved surface 111 are arranged relatively spaced apart.

[0076] In the above implementation, the cooperation between the first curved surface 410 and the second curved surface 111 can provide a certain space for the swing of the lever assembly 40, thereby avoiding interference between the lever assembly 40 and the panel 10 when swinging.

[0077] Figure 4 This is a cross-sectional view of the switch, combined with Figure 4 For example, during the swinging of the lever assembly 40, the spacing distance d between the relative first curved surface 410 and the second curved surface 111 does not exceed 0.3 mm, and the spacing distance is the shortest distance between the first curved surface 410 and the second curved surface 111 in the direction perpendicular to the pivot axis of the lever assembly 40.

[0078] Such a design can effectively limit the gap between the lever assembly 40 and the panel 10, and can block the arc light from flashing out of the gap between the panel 10 and the lever assembly 40. In addition, it can also eliminate potential safety hazards and improve the reliability of the switch.

[0079] For example, the first curved surface 410 and the second curved surface 111 are both part of a cylindrical surface. The axis of the cylindrical surface to which the first curved surface 410 belongs and the axis of the cylindrical surface to which the second curved surface 111 belongs are both coaxial with the swing axis of the lever assembly 40. In this way, it is possible to ensure that the distance between the first curved surface 410 and the second curved surface 111 remains consistent during the swinging process of the lever assembly 40, thereby ensuring that the lever assembly 40 shields the external through hole 120.

[0080] Of course, in other embodiments, the first curved surface 410 and the second curved surface 111 may also be other shapes, such as conical surfaces, spherical surfaces, etc., and the present disclosure does not limit this.

[0081] In this embodiment, during the swinging process of the lever assembly 40 , when the switch is turned on or off, the spacing distance between the opposite first curved surface 410 and the second curved surface 111 is the minimum value.

[0082] In actual use, the switch is in the on state or the off state most of the time. When the switch is turned on or off, the spacing between the first curved surface 410 and the second curved surface 111 is the minimum, which can effectively ensure that the gap between the lever assembly 40 and the panel 10 is the minimum. In this way, on the one hand, it plays a role of shading, and on the other hand, it can prevent dust and other debris from entering the inside of the switch.

[0083] In order to achieve the change in the spacing distance between the first curved surface 410 and the second curved surface 111, the first curved surface 410 and the second curved surface 111 have different curvature radii. The curvature radius is used to describe the degree of curvature change of a curve at a certain point on the curve. Take an extreme example: the degree of curvature is the same everywhere on a circle, so the curvature radius of the circle is the radius of the circle. Since a straight line is not curved, the radius of the circle tangent to the straight line at that point can be arbitrarily large, so the curvature radius is 0, so the straight line has no curvature radius. In general, the larger the radius of curvature, the smaller the curvature, and vice versa.

[0084] Figure 5 is a schematic diagram of the curvature radius of the first curved surface and the second curved surface. Figure 5 R in the figure is a virtual circle corresponding to the first curved surface 410, which can be regarded as the swing trajectory of the lever assembly 40, and r is a virtual circle corresponding to the second curved surface 111. Figure 5 For example, the radius of curvature corresponding to the first curved surface 410 is smaller than the radius of curvature corresponding to the second curved surface 111. In other words, the second curved surface 111 is smoother than the first curved surface 410, and the first curved surface 410 is steeper than the second curved surface 111.

[0085] In order to ensure the normal swing of the lever assembly 40 and avoid interference between it and the panel 10, the distance between the first curved surface 410 and the second curved surface 111 is not less than 0.25 mm. On this basis, the curvature radius of the second curved surface 111 is 8 to 8.8 mm, 8.4 mm in this embodiment, and the curvature radius of the first curved surface 410 is 6 to 8.8 mm, 6.5 to 8.4 mm in this embodiment.

[0086] It is worth noting that in the above implementation, the first curved surface 410 and the second curved surface 111 are regarded as an arc surface. In other embodiments, the first curved surface 410 and the second curved surface 111 may not be arc surfaces, but curved surfaces with varying curvatures. For example, if a circle with the same curvature as a point on a curve can be found, then the radius of curvature of this point on the curve is the radius of the circle (the radius of curvature of this point, and other points have other radii of curvature). In other words, the curve is differentiated as much as possible until it is finally approximated as an arc, and the radius corresponding to this arc is the radius of curvature of the point on the curve.

[0087] The present disclosure does not limit the shapes of the first curved surface 410 and the second curved surface 111 , as long as the spacing distance between the first curved surface 410 and the second curved surface 111 is a minimum when the switch is turned on or off.

[0088] In some examples, the first curved surface 410 is symmetrical about the central axis of the lever assembly 40 , and the second curved surface 111 is symmetrical about the central axis of the outer through hole 120 .

[0089] In this way, when the lever assembly 40 is in the middle position, the central axis of the lever assembly 40 is coaxial with the central axis of the outer through hole 120, and the spacing distance between the first curved surface 410 and the second curved surface 111 is the maximum value. As the lever assembly 40 swings sideways, the spacing distance between the first curved surface 410 and the second curved surface 111 gradually decreases until the lever assembly 40 swings to the dead point position, the switch is turned on or off, and the spacing distance between the first curved surface 410 and the second curved surface 111 is the minimum value.

[0090] In actual use, the switch is mounted on a wall, and the lever assembly 40 swings in a vertical direction. Then, the first end of the lever assembly 40 in the swinging direction faces the ceiling, and the second end of the lever assembly 40 in the swinging direction faces the ground. Considering that the user usually looks down at the switch, the user looks at the first end of the lever assembly 40 in the swinging direction (see FIG. Figure 6 , Figure 6 The solid arrow in the middle indicates the line of sight. Based on this, in other examples, when the lever assembly 40 is located at the first end of the swinging direction, the spacing distance between the opposite first curved surface 410 and the second curved surface 111 is the minimum value.

[0091] For example, when the lever assembly 40 is located at the first end of the swing direction, the spacing distance between the first curved surface 410 and the second curved surface 111 is 0.05-0.09 mm, and is 0.07 mm in this embodiment. When the lever assembly 40 is located at the second end of the swing direction, the spacing distance between the first curved surface 410 and the second curved surface 111 is 0.18-0.38 mm, and is 0.28 mm in this embodiment.

[0092] See again Figure 4 In the present embodiment, the panel 10 has at least two shading members 140 on one side facing the shell 20, each shading member 140 is close to the external through hole 120, each shading member 140 is respectively located on opposite sides of the plane where the swing trajectory of the lever assembly 40 is located, and each shading member 140 is respectively opposite to the lever assembly 40.

[0093] In the above implementation, since the shading members 140 are close to the outer through hole 120 and each shading member 140 is opposite to the lever assembly 40, the arc light can be blocked from flashing out from the gap between the panel 10 and the lever assembly 40. In addition, since each shading member 140 is located on the opposite sides of the plane where the swing track of the lever assembly 40 is located, the shading member 140 will not interfere with the swing of the lever assembly 40.

[0094] Exemplarily, there are two shading members 140, which are respectively located on opposite sides of the plane where the swing track of the lever assembly 40 is located. The shading member 140 is a plate-shaped structural member, and the planes where the shading member 140 and the swing track of the lever assembly 40 are located are parallel to each other.

[0095] In this embodiment, the side of the panel 10 facing the housing 20 further comprises a surrounding plate 150 and a supporting rib 160, and both the surrounding plate 150 and the supporting rib 160 are connected to the side of the panel 10 facing the housing 20. The surrounding plate 150 surrounds the shading member 140, one end of the supporting rib 160 is connected to the shading member 140, and the other end of the supporting rib 160 is connected to the surrounding plate 150.

[0096] In the above implementation, each shading member 140 is located in the space enclosed by the enclosure 150 , and the shading member 140 and the enclosure 150 are connected by a supporting member, which can play a supporting role for the shading member 140 .

[0097] Figure 7 is a schematic diagram of the structure of the first curved surface 410, combined with Figure 7In this embodiment, the panel 10 has a first sliding tooth on one side facing the shell 20, and the first sliding tooth is close to the external through hole 120. The lever assembly 40 has a second sliding tooth 450 on the outer wall facing the panel 10. The extension directions of the second sliding tooth 450 and the first sliding tooth are consistent with the swing trajectory of the lever assembly 40. The second sliding tooth 450 is meshed with the first sliding tooth, and the second sliding tooth 450 can move relative to the first sliding tooth.

[0098] In the above implementation, the first sliding tooth and the second sliding tooth 450 are meshed with each other, so that the matching area between the panel 10 and the lever assembly 40 can be increased. Compared with the first curved surface 410 and the second curved surface 111 directly facing each other as described above, such a design is more conducive to shielding arc light.

[0099] It is worth noting that, although the first sliding tooth and the second sliding tooth 450 are meshed, they are not completely meshed and locked, but when the lever assembly 40 swings, a sliding tooth phenomenon will occur between the two, so the lever assembly 40 can still swing normally.

[0100] In order to ensure that the first sliding tooth and the second sliding tooth 450 have a sliding tooth phenomenon, the tooth tips of the first sliding tooth and the second sliding tooth 450 are both arc-shaped.

[0101] Figure 8 The schematic diagram of the panel structure is shown in Figure 2. Figure 8 In this embodiment, a side of the panel 10 facing away from the housing 20 has an outer recess 170 , and the outer through hole 120 is located in the outer recess 170 .

[0102] In the above implementation, setting the external through hole 120 in the outer recess 170 can effectively reduce the length dimension of the external through hole 120, that is, the wall thickness of the panel 10 corresponding to the inner edge of the external through hole 120, thereby reducing the accumulation of dust at the external through hole 120.

[0103] Exemplarily, the outer recess 170 and the inner recess 110 are respectively located on opposite sides of the panel 10 and arranged opposite to each other. In this way, the length dimension of the outer through hole 120 can be further reduced.

[0104] In this embodiment, the panel 10 is a two-color injection molding structural member, so that the manufacturing efficiency of the panel 10 can be guaranteed on the one hand, and the structural strength of the panel 10 can be guaranteed on the other hand.

[0105] Exemplarily, the panel 10 includes a first sub-board body 10a and a second sub-board body 10b, and the first sub-board body 10a and the second sub-board body 10b are bonded together by a two-color injection molding process.

[0106] Fig. 9 This is a schematic diagram of the assembly between the lever assembly and the panel. Fig. 9 and Figure 4 The main difference between the two is the matching structure between the lever assembly and the panel, combined with Fig. 9 In this embodiment, the panel 10 has a light shielding ring 130 on one side facing the housing 20, and the light shielding ring 130 is arranged around the outer through hole 120. The outer wall of the lever assembly 40 facing the panel 10 has a countersunk hole 420, and the light shielding ring 130 is accommodated in the countersunk hole 420 (see Fig.10 ).

[0107] The shading ring 130 is accommodated in the countersunk hole 420, so that the outer wall of the shading ring 130 is opposite to the inner wall of the countersunk hole 420, and the end face of the shading ring 130 is opposite to the inner bottom face of the countersunk hole 420. Through the mutual cooperation between the shading ring 130 and the countersunk hole 420, the arc light can be effectively shielded.

[0108] Exemplarily, the light shielding ring 130 is located at the second curved surface 111, and its end surface facing away from the second curved surface 111 is consistent with the curvature radius of the second curved surface 111, so that the end surface of the light shielding ring 130 can match the first curved surface 410. In addition, the outer wall profile of the light shielding ring 130 matches the inner wall profile of the counterbore 420, thereby avoiding interference and collision between the light shielding ring 130 and the counterbore 420.

[0109] It is worth noting that although Figure 3 The light shielding ring 130 and the counterbore 420 are not shown. Fig. 9 The light shielding member is not shown in the figure, but the light shielding ring 130, the counterbore 420 and the light shielding member can be provided at the same time. Figure 3 Shown only with a shade, or with Fig. 9 Only the light shielding ring 130 and the counterbore 420 are shown, but the present disclosure is not limited thereto.

[0110] In this embodiment, the outer wall of the lever assembly 40 has a wing 440 , which extends along the pivot axis of the lever assembly 40 and is located on one side of the plane where the swing trajectory of the lever assembly 40 is located. The wing 440 is opposite to the inner edge of the outer through hole 120 .

[0111] In the above implementation, the side wing 440 extends along the pivot axis of the lever assembly 40, so the side wing 440 can increase the size of the lever assembly 40 in the direction of the pivot axis, thereby ensuring that the side wing 440 covers the external through hole 120 located on the side of the moving trajectory of the lever assembly 40. In this way, even if the lever assembly 40 swings, it can ensure continuous covering of the external through hole 120.

[0112] In this embodiment, the first curved surface 410 extends to the side of the wing 440 facing the panel 10. Such a design enables the side of the wing 440 facing the panel 10 to have the same beneficial effects as the first curved surface 410, which will not be described in detail.

[0113] Exemplarily, there are two side wings 440, one side wing 440 is located on one side of the plane where the swing trajectory of the lever assembly 40 is located, and the other side wing 440 is located on the other side of the plane where the swing trajectory of the lever assembly 40 is located, thereby further ensuring the shielding effect of the side wing 440 on the external through hole 120.

[0114] Through the above-mentioned contents, it is possible to effectively block the arc light from flashing out from the gap between the lever assembly 40 and the panel 10. The following further describes the contents related to blocking the arc light from flashing out from the gap between the lever assembly 40 and the housing 20.

[0115] Fig.11 The assembly diagram of the lever assembly and the housing is shown in FIG. Fig.11 In this embodiment, the housing 20 has an inner through hole 210 , and the lever assembly 40 is inserted into the inner through hole 210 to cover the inner through hole 210 .

[0116] In the above implementation, since the lever assembly 40 is inserted into the inner through hole, the lever assembly shields the inner through hole 210. In this way, both the outer through hole 120 and the inner through hole 210 are shielded, effectively preventing the arc from flashing out of the switch.

[0117] In this embodiment, the orthographic projection of the lever assembly 40 on the plane where the inner through hole 210 is located covers the inner through hole 210 .

[0118] In the above implementation, the positional relationship between the inner through hole 210 and the housing 20 is designed in this way, so as to ensure the shielding effect of the lever assembly 40 on the inner through hole 210. In addition, since the orthographic projection of the lever assembly 40 is guaranteed to cover the inner through hole 210, even if the lever assembly 40 swings, the lever assembly 40 can always play the role of shielding the inner through hole 210.

[0119] Continue to see Fig.11 In this embodiment, the housing 20 has a receiving groove 220 on one side facing the panel 10 , the inner through hole 210 is located at the bottom of the receiving groove 220 , and the lever assembly 40 is received in the receiving groove 220 .

[0120] Since the inner through hole 210 is located at the bottom of the receiving groove 220 , the inner through hole 210 can be effectively shielded by the groove wall of the receiving groove 220 , thereby preventing the arc light from being directly emitted from the inner through hole 210 .

[0121] In this embodiment, the groove wall of the receiving groove 220 has a roughened layer.

[0122] In the above implementation, the groove wall of the accommodating groove 220 is designed as a roughened layer, which can reflect the arc light irradiated on the groove wall of the accommodating groove 220 in the form of diffuse reflection, thereby reducing the brightness of the reflected arc light, that is, reducing the brightness of the arc light transmitted to the external through hole 120.

[0123] In this embodiment, the switch further includes a shading cover (not shown), which is located in the receiving groove 220 , is sleeved outside the lever assembly 40 , and is located on the side of the side wing 440 facing the bottom of the receiving groove 220 , so that the shading cover blocks the inner through hole 210 .

[0124] For example, the shading cover is a conical structure, the smaller end of the shading cover is connected to the lever assembly 40, and the larger end of the shading cover is connected to the bottom of the receiving groove 220. Such a design can, on the one hand, prevent the shading cover from affecting the swing of the lever assembly 40, and on the other hand, ensure that the shading cover plays a sufficient shielding role for the inner through hole 210.

[0125] For example, the shading cover is made of a flexible material. With such a design, the shading cover can be deformed adaptively with the swing of the lever assembly 40 , thereby further ensuring that the shading cover will not affect the swing of the lever assembly 40 .

[0126] Fig.12 is a cross-sectional view of the shell, combined with Fig.12 In this embodiment, a core-pulling injection channel 230 is provided inside the shell 20 , a first port of the core-pulling injection channel 230 is located on the outer wall of the shell 20 , and a second port of the core-pulling injection channel 230 is located on the groove wall of the accommodating groove 220 .

[0127] In the above implementation, the core-pulling injection molding channel 230 is used to accommodate the core-pulling during the injection molding process of the shell 20. Since the core-pulling injection molding channel 230 is located inside the shell 20, it will not cause the shell 20 to be hollowed out, and can ensure that the shell 20 is an integral structure, which is beneficial to shielding the on-off component 30 accommodated inside the shell 20.

[0128] It is worth noting that the positions of the first port and the second port of the core-pulling injection molding channel 230 can be adjusted according to actual needs, and it is only necessary to ensure that the core-pulling injection molding channel 230 that is finally formed is located inside the shell 20.

[0129] Exemplarily, the shell 20 has a hinge seat 240 on one side facing the panel 10 . The hinge seat 240 is located in the accommodating groove 220 . The hinge seat 240 is pivotally connected to the lever assembly 40 . The pivot socket of the hinge seat 240 is opposite to the second port of the core-pulling injection channel 230 .

[0130] In the above implementation, the hinge seat 240 is used to provide a mounting base for the lever assembly 40. Since the hinge seat 240 needs to accommodate the pivot axis of the lever assembly 40, the hinge seat 240 has a pivot socket. The second port of the core-pulling injection channel 230 is arranged opposite to the pivot socket of the hinge seat 240, so that during the injection molding process, the core-pulling can be extended into the pivot socket of the hinge seat 240 through the second port of the core-pulling injection channel 230, thereby increasing the moving range of the core-pulling, which is beneficial to the injection molding process.

[0131] In this embodiment, the hinge seat 240 has a first guide bevel 241 on one side facing the lever assembly 40, and the first guide bevel 241 is close to the notch of the accommodating groove 220. The end of the pivot axis of the lever assembly 40 has a second guide bevel 460, and the second guide bevel 460 is used to slide in contact with the first guide bevel 241.

[0132] During the process of pivoting the lever assembly 40 and the housing 20, the first guide bevel 241 and the second guide bevel 460 are in sliding contact. With the mutual cooperation of the first guide bevel 241 and the second guide bevel 460, the pivot axis of the lever assembly 40 is guided into the pivot socket of the hinge seat 240, thereby realizing the pivotal assembly between the lever assembly 40 and the housing 20.
