[0003] A switch is a common electrical component that is widely used in electrical systems to switch circuits on and off.

[0004] In the related art, one type of switch is a toggle switch, which primarily consists of a panel, a housing, a toggle lever, and hardware components. The panel covers one side of the housing, the hardware components are located within the housing, and the toggle lever is pivotally connected to the housing. One end of the toggle lever extends through the panel and is located outside the housing, while the other end contacts the hardware components. When the user toggles the toggle lever, it moves the hardware components, causing the moving contact and stationary contact piece within the hardware components to contact or separate, turning the switch on or off.

[0005] However, since the lever needs to be moved by the user, it protrudes from the panel, which can easily damage the lever when the switch is accidentally dropped. Utility Model Content

These drawings and textual descriptions are not intended to limit the scope of the present disclosure in any way, but rather to illustrate the concepts of the present disclosure to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0053] 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.

[0054] The embodiment of the present disclosure provides a switch, Figure 1 For the structural diagram of the switch, see Figure 1 The switch includes a panel 100, a housing 200, a switch assembly 300, and a lever assembly 400. The panel 100 is disposed on one side of the housing 200. The switch assembly 300 is located within the housing 200 and is capable of swinging relative to the housing 200. The lever assembly 400 is pivotally connected to the housing 200 and contacts the switch assembly 300. The lever assembly 400 is configured to swing the switch assembly 300 to turn the switch on or off.

[0055] When the switch provided by the embodiment of the present disclosure turns the electrical system on and off, the user toggles the lever assembly 400, causing it to swing relative to the housing 200, thereby causing the lever assembly 400 to swing along with the on / off assembly 300. During the swinging of the on / off assembly 300, the switch can be turned on or off, thereby turning the electrical system on and off.

[0056] In some examples, the switch assembly 300 is a seesaw with silver dots at both ends of the seesaw, and the swing axis of the seesaw is located between the two ends of the seesaw. In this design, the switch is a seesaw switch.

[0057] In other examples, the switch assembly 300 is a pendulum, 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 type switch.

[0058] Figure 2 For an exploded view of the lever assembly, see Figure 2 In this embodiment, the lever assembly includes a transition piece 10, a lever 20, a fixing structure 30, and a handle 40. The transition piece 10 has a slot 110, into which the first end of the lever 20 is inserted. The fixing structure 30 is located in the slot 110 to fix the transition piece 10 and the lever 20. The handle 40 is connected to the second end of the lever 20.

[0059] The lever assembly provided by the embodiment of the present disclosure can be configured in a switch. The lever assembly includes a transition piece 10, a lever piece 20 and a handle 40. The lever piece 20 is the operating part of the lever assembly, and the handle 40 is connected to the end of the lever piece 20 for the user to shift. The transition piece 10 provides a bearing base for the lever piece 20 for the lever assembly, on the one hand, so that the lever piece 20 can be inserted into the slot 110 of the transition piece 10, and on the other hand, it can serve as a trigger part for triggering the on-off assembly 300 of the switch to turn the switch on or off. Since the lever assembly also includes a fixing structure 30, the fixing structure 30 is located in the slot 110 and can fix the transition piece 10 and the lever piece 20, thereby effectively improving the connection firmness between the transition piece 10 and the lever piece 20, thereby improving the structural strength of the lever assembly, and further improving the overall reliability of the switch.

[0060] That is, by providing the fixing structure 30 in the slot 110 of the transition piece 10 and using the fixing structure 30 to fix the transition piece 10 and the lever 20 , the structural strength of the lever assembly is effectively improved, thereby improving the overall reliability of the switch.

[0061] In this embodiment, two implementations of the fixing structure 30 are provided, which are described below. Of course, it is worth noting that although two implementations of the fixing structure 30 are provided in this embodiment, the fixing structure 30 is not limited to being implemented in only these two ways.

[0062] Continue to see Figure 2 In this embodiment, the fixing structure 30 includes a notch 310 and a rib 320, one of the notch 310 and the rib 320 is located at the first end of the lever member 20, and the other of the notch 310 and the rib 320 is located at the bottom of the slot 110, and the rib 320 is inserted into the notch 310.

[0063] In the above implementation, the mutual insertion between the rib 320 and the notch 310 can play a role in positioning and fixing the lever member 20 and the transition member 10, thereby effectively improving the connection firmness between the lever member 20 and the transition member 10.

[0064] In some examples, the notch 310 is located at the first end of the lever member 20, and the rib 320 is located at the bottom of the slot 110. In other examples, the notch 310 is located at the bottom of the slot 110, and the rib 320 is located at the first end of the lever assembly. Both arrangements of the notch 310 and rib 320 can effectively improve the connection between the lever member 20 and the transition member 10. The preferred arrangement can be selected based on actual needs and is not limited in this disclosure.

[0065] For example, one side of the rib 320 facing the notch 310 is in an arc shape. This design facilitates the insertion of the rib 320 into the notch 310, thereby improving the assembly convenience between the lever member 20 and the transition member 10.

[0066] Figure 3 This is a cross-sectional view of the lever assembly, combined with Figure 3 In this embodiment, there is a gap 330 between the inner wall of the notch 310 and the outer wall of the rib 320 , and the gap 330 and the slot 110 are filled with adhesive.

[0067] In the above implementation, since the slot 110 is filled with adhesive, the lever 20 and the transition piece 10 can be bonded together, further improving the connection strength between the lever 20 and the transition piece 10. Furthermore, since the gap 330 between the inner wall of the notch 310 and the outer wall of the rib 320 is also filled with adhesive, the contact area between the adhesive and the lever 20 and transition piece 10 is effectively increased, thereby enhancing the adhesive bonding effect.

[0068] During assembly of the lever 20 and transition piece 10, the adhesive is first filled into the slot 110, and then the lever 20 is inserted into the slot 110. As the lever 20 is inserted into the slot 110, the adhesive automatically fills the gap 330 between the inner wall of the notch 310 and the outer wall of the rib 320. This improves assembly efficiency while preventing the adhesive from overflowing from the slot 110.

[0069] Exemplarily, the adhesive is glue, which can achieve bonding between the lever member 20 and the transition member 10 .

[0070] Figure 4 This is an exploded view of another lever assembly. Figure 4 and Figure 2 The main difference lies in the different fixing methods between the shifting rod member 20 and the transition member 10, that is, the different implementation methods of the fixing structure 30.

[0071] See also Figure 4 In this embodiment, the fixing structure 30 includes an injection hole 340 , which is close to the first end of the shifting lever 20 , and the transition piece 10 is at least partially embedded in the injection hole 340 .

[0072] In the above implementation, the lever member 20 is a metal structural member, and the transition member 10 is a plastic structural member. During the injection molding process of the transition member 10, part of the injection molding material will enter the injection molding hole 340, thereby improving the connection strength between the lever member 20 and the transition member 10 after the transition member 10 is molded.

[0073] Furthermore, since the lever member 20 is a metal structural member, the structural strength of the lever member 20 can be ensured, thereby preventing the lever member 20 from breaking under collision impact.

[0074] It is worth noting that although Figure 2 、 3 Only the notch 310 and the rib 320 are shown, but the injection hole 340 is not shown. Figure 4 Only the injection hole 340 is shown, without the notch 310 and rib 320. However, the two implementations of the fixing structure 30 are not mutually exclusive. In some examples, the two implementations of the fixing structure 30 can coexist. For example, the notch 310 is located at the first end of the lever 20, the rib 320 is located at the bottom of the slot 110, the injection hole 340 is near the first end of the lever 20, and the transition piece 10 is at least partially embedded in the injection hole 340.

[0075] That is to say, the two implementation methods of the fixing structure 30 can be selected either alone or simultaneously, and the present disclosure does not impose any restrictions on this.

[0076] See again Figure 2 In this embodiment, the lever member 20 has an injection molding groove 210 at a portion close to the second end thereof, and the handle 40 is at least partially embedded in the injection molding groove 210 .

[0077] In the above implementation, the handle 40 is set at the second end of the lever member 20 by injection molding. Since the outer wall of the lever member 20 has an injection molding groove 210 near the second end, during the process of injection molding the handle 40, the material will flow into the injection molding groove 210, so that the handle 40 is at least partially embedded in the injection molding groove 210, thereby improving the connection strength between the handle 40 and the lever member 20.

[0078] Exemplarily, the handle 40 is a transparent structural member.

[0079] Exemplarily, the handle 40 , the lever member 20 , and the transition member 10 are integrally injection molded.

[0080] Figure 5 The structure diagram of the lever member 20 is shown in FIG. Figure 5 In this embodiment, the outer wall of the lever member 20 has a reinforcing rib 220 , and the reinforcing rib 220 extends along the length of the lever member 20 .

[0081] In the above implementation, since the reinforcing rib 220 extends along the length of the lever member 20 , it is possible to prevent the lever member 20 from being easily broken due to its long length.

[0082] For example, there are multiple reinforcing ribs 220, and the multiple reinforcing ribs 220 are arranged in parallel at intervals. Such a design can further improve the structural strength of the lever member 20.

[0083] Figure 6 is a schematic structural diagram of the transition piece 10, combined with Figure 6 In this embodiment, the transition piece 10 includes a lever portion 120 and a pivot portion 130, the first end of the lever portion 120 is connected to the pivot portion 130, the outer wall of the pivot portion 130 has a pivot axis 140, and the slot 110 is located on the side of the pivot portion 130 facing away from the lever portion 120.

[0084] In the above implementation, the pivotal portion 130 is used to support the lever member 20, and is pivotally connected to the switch housing 200 through the pivot shaft 140, so that the lever portion 120 can swing relative to the housing 200 along with the pivotal portion 130 to toggle the switch on / off assembly 300, so that the switch is turned on or off.

[0085] See again Figure 3In this embodiment, the lever portion 120 defines a channel 121. Channel 121 extends along the length of the lever portion 120 and passes through the second end of the lever portion 120. The transition piece 10 further includes a ball 170 and an elastic member 180. The first end of the ball 170 is movably positioned within the channel 121, and the second end of the ball 170 contacts the on / off assembly 300 of the switch. The elastic member 180 is positioned within the channel 121 and is connected to the lever portion 120 and the ball 170, respectively.

[0086] In the above implementation, the pin 170 is located within the channel 121 and is connected to the lever portion 120 via the elastic member 180. When the pin 170 contacts the switch assembly 300, the elastic member 180 is compressed, ensuring that the pin 170 maintains close contact with the switch assembly 300, thereby driving the switch assembly 300 to swing. Furthermore, because the pin 170 is located within the channel 121, the sliding fit between the outer circumferential wall of the pin 170 and the inner circumferential wall of the channel 121 allows the pin 170 to slide stably relative to the lever portion 120, preventing unnecessary shaking.

[0087] Exemplarily, the second end of the pin 170 is conical, and the apex of the second end of the pin 170 contacts the switching assembly 300 .

[0088] When the pin 170 moves the on-off assembly 300, the second end of the pin 170 will slide on the on-off assembly 300. Therefore, the second end of the pin 170 is designed to be conical, and the apex of the cone contacts the on-off assembly 300. This can effectively reduce the contact area between the pin 170 and the on-off assembly 300, making it easier for the pin 170 to move the on-off assembly 300 and avoiding the pin 170 from getting stuck on the on-off assembly 300.

[0089] In this embodiment, when the pin 170 is in the first position of the switch assembly 300, the switch is on, and when the pin 170 is in the second position of the switch assembly 300, the switch is off. Before the pin 170 moves to the first position or the second position, the second end of the lever portion 120 can contact the switch assembly 300.

[0090] For example, when the switch is on, the ball 170 is in the first position. At this time, if you want to turn off the switch, that is, turn the handle 40, so that the transition piece 10 swings, and the ball 170 moves from the first position to the second position. Before the ball 170 moves to the second position, the second end of the lever portion 120 first contacts the on-off assembly 300, thereby applying force to the on-off assembly 300, causing the on-off assembly 300 to start swinging. Since there is a hard contact between the second end of the lever portion 120 and the on-off assembly 300, a stronger pulling force can be provided, thereby preventing the on-off assembly 300 from being unable to swing normally due to the adhesion of its own silver points. The process of the ball 170 moving from the second position to the first position is similar to the above process and will not be repeated here.

[0091] See again Figure 6 In this embodiment, the transition piece 10 also includes a rib 150, which is connected to the outer wall of the lever portion 120, and the rib 150 extends along the length direction of the lever portion 120, and at least part of the rib 150 is located at the second end of the lever portion 120.

[0092] In the above implementation, the second end of the lever portion 120 contacts the on-off assembly 300 through the rib 150, which can reduce the contact area between the transition piece 10 and the on-off assembly 300, thereby reducing the friction between the lever portion 120 and the on-off assembly 300, and thus avoiding jamming between the lever portion 120 and the on-off assembly 300.

[0093] For example, there are two abutment ribs 150, which are arranged parallel to each other and spaced apart. This design can improve the stability of the abutment ribs 150 exerting force on the switch assembly 300, and avoid the problem of the switch assembly 300 being skewed.

[0094] Continue to see Figure 6 In this embodiment, the transition piece 10 further includes a side wing 160 , which is connected to the outer wall of the pivot portion 130 and extends along the axis of the pivot shaft 140 .

[0095] In the above implementation, by providing the side wings 160 on the outer wall of the pivotal portion 130, on the one hand, the stability of the transition piece 10 during swinging can be improved, and on the other hand, it can also play a certain shielding role, thereby preventing foreign objects from falling into the switch and arc flashes caused by on-off switching inside the switch. This not only improves the reliability of the switch, but also ensures electrical safety.
