Description

[0001] This disclosure claims priority to Chinese patent application No. 202421159239.9, filed on May 24, 2024, with the utility model name “SWITCH”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure belongs to the field of electronic technology, and in particular relates to a switch. Background Art

[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 pass through the panel when installing the switch, the through-hole in the panel is designed to be larger to ensure the lever can pass through the panel. This results in a large gap between the panel and the lever, which can easily cause the lever to fall out of the through-hole when impacted. 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 exploded view of the switch, see Figure 1The switch includes a panel 10, a housing 20, a switching assembly 30, a lever assembly 40 and an anti-slip structure 50.

[0055] Figure 2 This is a cross-sectional view of the switch, combined with Figure 2 In this embodiment, the panel 10 is provided on one side of the housing 20, and the panel 10 has a through hole 120. The on-off assembly 30 is located in the housing 20 and can swing relative to the housing 20. The lever assembly 40 is pivotally connected to the housing 20, the first end of the lever assembly 40 is located in the housing 20 and contacts the on-off assembly 30, and the second end of the lever assembly 40 passes through the through hole 120. The lever assembly 40 is configured to swing the on-off assembly 30 to turn the switch on or off. The anti-slip structure 50 is used to prevent the lever assembly 40 from falling out of the through hole 120. The anti-slip structure 50 is located at at least one of the following positions: between the lever assembly 40 and the panel 10, and between the lever assembly 40 and the housing 20.

[0056] When the switch provided by the embodiment of the present disclosure turns the electrical system on and off, the user toggles the second end of the lever assembly 40, causing the lever assembly 40 to swing relative to the housing 20. This causes the second end of the lever assembly 40 to swing the on / off assembly 30. As the on / off assembly 30 swings, the switch can be turned on or off, thereby turning the electrical system on and off.

[0057] Furthermore, since the anti-slip structure 50 is provided at at least one location between the lever assembly 40 and the panel 10, or between the lever assembly 40 and the housing 20, the anti-slip structure 50 can at least ensure the assembly security between the lever assembly 40 and the panel 10, or between the lever assembly 40 and the housing 20. Thus, the lever assembly 40 can be effectively prevented from slipping out of the through hole, thereby improving the reliability of the switch.

[0058] In some examples, the switch assembly 30 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.

[0059] In other examples, the switch assembly 30 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.

[0060] As can be seen from the foregoing, the provision of the anti-slip structure 50 can ensure the assembly firmness of the lever assembly 40, thereby preventing the lever assembly 40 from slipping out of the through hole under collision impact.

[0061] When the anti-slip structure 50 is located at different positions, its structure is also different. The following describes the anti-slip structure 50 located between the lever assembly and the panel, and the anti-slip structure 50 located between the lever assembly and the housing.

[0062] Figure 3 This is the assembly diagram between the lever assembly and the panel, combined with Figure 3 In this embodiment, when the anti-slip structure 50 is located between the lever assembly 40 and the panel 10 , the anti-slip structure 50 is used to prevent the lever assembly 40 from swinging at the panel 10 .

[0063] It is worth noting that the swing of the lever assembly 40 refers to the rotation of the lever assembly 40 about the pivot axis between the lever assembly 40 and the housing 20. This rotation is normal rotation of the lever assembly 40. The yaw of the lever assembly 40 refers to the rotation of the lever assembly 40 about an axis other than the pivot axis between the lever assembly 40 and the housing 20. This rotation is abnormal rotation of the lever assembly 40 after a collision.

[0064] In the above implementation, the anti-slip structure 50 is disposed between the lever assembly 40 and the panel 10. The anti-slip structure 50 prevents the lever assembly 40 from swinging, particularly from swinging toward the panel 10. Consequently, when the second end of the lever assembly 40 is impacted by a collision, the lever assembly 40 may swing. However, the anti-slip structure 50 prevents the lever assembly 40 from deforming due to the swinging force and subsequently falling out of the through-hole 120.

[0065] Continue to see Figure 3 In this embodiment, the anti-slip structure 50 includes at least two stoppers 510, each of which is connected to a side of the panel 10 facing the shell 20, and each of which is located on opposite sides of the plane of the swing trajectory of the lever assembly 40, and each of which is opposite to the lever assembly 40 and located on the swing trajectory of the lever assembly 40.

[0066] In the above implementation, the two stops 510 are located on opposite sides of the lever assembly 40, that is, on opposite sides of the plane of the swing trajectory of the lever assembly 40. This prevents the stops 510 from interfering with the swing of the lever assembly 40. Furthermore, the stops 510 suppress the deflection of the lever assembly 40 after a collision, thereby preventing deformation of the lever assembly 40 due to the deflection and subsequent disengagement from the through-hole 120.

[0067] For example, there are two stoppers 510, which are located on opposite sides of the plane of the swing trajectory of the lever assembly 40. The stoppers 510 are plate-shaped components, and the stoppers 510 and the plane of the swing trajectory of the lever assembly 40 are parallel to each other.

[0068] In this embodiment, the anti-slip structure 50 further includes a panel 530 and a support rib 540, both of which are connected to the side of the panel 10 facing the housing 20. The panel 530 surrounds the stopper 510, one end of the support rib 540 is connected to the stopper 510, and the other end of the support rib 540 is connected to the panel 530.

[0069] In the above implementation, each stopper 510 is located in the space enclosed by the enclosure 530 , and the stopper 510 and the enclosure 530 are connected by a support member, which can support the stopper 510 .

[0070] Figure 4 It is a structural diagram of the lever assembly, combined with Figure 3 and Figure 4 In this embodiment, the outer wall of the lever assembly 40 has a side wing 440. The side wing 440 extends along the pivot axis of the lever assembly 40 and is located on one side of the plane of the swing trajectory of the lever assembly 40. The side wing 440 is opposite to the stopper 510.

[0071] In the above implementation, the end of the side wing 440 is opposite to the stopper 510. When the lever assembly 40 deflects, the mutual restraint between the side wing 440 and the stopper 510 can prevent the lever assembly 40 from being deformed due to the deflection force and then escaping from the through hole 120.

[0072] Illustratively, the outer edge size of the side wing 440 is larger than the aperture of the through hole 120. In this way, the side wing 440 increases the overall size of the lever assembly 40 along the axial direction of the through hole 120, thereby preventing the lever assembly 40 from escaping from the through hole.

[0073] 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 is opposite to a stopper 510, 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, and is opposite to another stopper 510, thereby further ensuring the anti-escape effect.

[0074] Figure 5 This is a schematic diagram of the assembly between the lever assembly and the housing, combined with Figure 5In this embodiment, when the anti-slip structure 50 is located between the lever assembly 40 and the housing 20 , the anti-slip structure 50 is used to prevent the lever assembly 40 from swinging at the housing 20 .

[0075] In the above implementation, the anti-slip structure 50 is disposed between the lever assembly 40 and the housing 20. The anti-slip structure 50 prevents the lever assembly 40 from swinging, particularly from swinging toward the housing 20. Consequently, when the second end of the lever assembly 40 is impacted by a collision, the lever assembly 40 may swing. However, the anti-slip structure 50 prevents the lever assembly 40 from deforming due to the swinging force and subsequently falling out of the through hole 120.

[0076] Continue to see Figure 5 In this embodiment, the anti-slip structure 50 includes two hinges 520, each hinge 520 is hinged to the lever assembly 40, each hinge 520 is connected to the side of the shell 20 facing the panel 10, each hinge 520 is located on opposite sides of the plane of the swing trajectory of the lever assembly 40, and each hinge 520 is opposite to the lever assembly 40 and is located on the swing trajectory of the lever assembly 40.

[0077] In the above implementation, the hinge seat 520 serves as the mounting base for the deflector lever assembly 40, enabling the deflector lever assembly 40 to swing relative to the housing 20. The two hinge seats 520 are located on opposite sides of the deflector lever assembly 40, that is, on opposite sides of the plane of the deflector lever assembly 40's swing trajectory. This prevents the hinge seats 520 from interfering with the swing of the deflector lever assembly 40. Furthermore, the hinge seats 520 act as a stop, suppressing the deflection of the deflector lever assembly 40 after a collision, thereby preventing deformation of the deflection-induced force and subsequent disengagement from the through-hole 120.

[0078] Combine Figure 4 and Figure 5 In this embodiment, the outer wall of the lever assembly 40 has a boss 411 and a pivot shaft 412. The boss 411 extends along the pivot axis of the lever assembly 40 and is located on one side of the plane of the swing trajectory of the lever assembly 40. The boss 411 is opposite the hinge seat 520. The pivot shaft 412 is connected to the end surface of the boss 411 and is rotatably inserted into the hinge seat 520.

[0079] In the above implementation, the pivot shaft 412 is rotatably inserted into the hinge seat 520 to achieve the pivotal connection between the lever assembly 40 and the hinge seat 520. Because the pivot shaft 412 is located at the end of the boss 411, once the pivot shaft 412 is properly inserted into the hinge seat 520, the end of the boss 411 can be aligned with the hinge seat 520. If the lever assembly 40 deflects, the mutual restraint between the boss 411 and the hinge seat 520 prevents the lever assembly 40 from deforming due to the deflection force and subsequently dislodging from the through hole 120.

[0080] Figure 6 This is a cross-sectional view of the switch, combined with Figure 6 In this embodiment, the anti-slip structure 50 is located between the lever assembly 40 and the panel 10, and between the lever assembly 40 and the housing 20. In other words, the anti-slip structure 50 is located between the lever assembly 40 and the panel 10, and between the lever assembly 40 and the housing 20. In this case, the anti-slip structure 50 includes a stopper 510 and a hinge seat 520.

[0081] Along the swing axis of the lever assembly 40, the distance between the lever assembly 40 and the stopper 510 is a first length a, and the size of the contact portion between the lever assembly 40 and the hinge seat 520 is a second length b, which is greater than the first length a.

[0082] In the above implementation, when the lever assembly 40 is subjected to a collision impact (in Figure 6 During the deflection process, the lever assembly 40 will take the hinge between itself and the hinge seat 520 as the center O (see Figure 6 During this process, the portion of the lever assembly 40 corresponding to the hinge seat 520 rotates more than the portion of the lever assembly 40 corresponding to the stopper 510. Therefore, by making the second length b greater than the first length a, it is possible to ensure that the portion of the lever assembly 40 corresponding to the hinge seat 520 and the portion corresponding to the stopper 510 will not fall out. In addition, during the deflection of the lever assembly 40, the portion of the lever assembly 40 corresponding to the hinge seat 520 will deflect toward the hinge seat 520 under the action of the lever principle and apply a force ( Figure 6 Indicated by f), the hinge seat 520 absorbs it to prevent the shift rod assembly 40 from excessive deflection and breaking.

[0083] See again Figure 4 In this embodiment, the lever assembly 40 includes a transition piece 420 and a lever piece 430. The transition piece 420 has a socket 421, a first end of the lever piece 430 is inserted into the socket 421, and a second end of the lever piece 430 passes through the through hole 120.

[0084] In the above implementation, the lever 430 is the operating portion of the lever assembly 40, configured for user manipulation. The transition piece 420 is the driving portion of the lever assembly 40, configured to drive the on / off assembly 30 to swing, thereby turning the switch on or off. The socket 421 provides a space for the lever 430 to be inserted, allowing it to be securely inserted into the transition piece 420.

[0085] In this embodiment, the lever member 430 has an injection hole 431 at a portion close to the first end thereof, and the transition member 420 is at least partially located in the injection hole 431 .

[0086] For example, the lever 430 is a metal structural member, and the transition member 420 is a plastic structural member. During the injection molding process of the transition member 420, some of the injection molding material will enter the injection hole 431. This can improve the connection strength between the lever 430 and the transition member 420 after the transition member 420 is formed. Furthermore, because the lever 430 is a metal structural member, the structural strength of the lever 430 is guaranteed, preventing the lever 430 from breaking under collision impact.

[0087] In this embodiment, the transition piece 420 defines a channel 424, which extends along the length of the transition piece 420 and passes through the first end of the transition piece 420. The lever assembly 40 further includes a pin 450 and an elastic member 460. The first end of the pin 450 is movably positioned within the channel 424, and the second end of the pin 450 contacts the on / off assembly 30. The elastic member 460 is positioned within the channel 424 and is connected to the transition piece 420 and the pin 450, respectively.

[0088] In the above implementation, the pin 450 is located within the channel 424 and is connected to the transition piece 420 via the elastic member 460. When the pin 450 contacts the switch assembly 30, the elastic member 460 is compressed, ensuring that the pin 450 maintains close contact with the switch assembly 30, thereby driving the switch assembly 30 to swing. Furthermore, because the pin 450 is located within the channel 424, the sliding fit between the outer circumferential wall of the pin 450 and the inner circumferential wall of the channel 424 allows the pin 450 to slide stably relative to the transition piece 420, preventing unnecessary shaking.

[0089] Exemplarily, the second end of the pin 450 is conical, and the apex of the second end of the pin 450 contacts the switching assembly 30 .

[0090] When the pin 450 moves the on-off assembly 30, the second end of the pin 450 will slide on the on-off assembly 30, so the second end of the pin 450 is designed to be conical, and the apex of the cone contacts the on-off assembly 30, which can effectively reduce the contact area between the pin 450 and the on-off assembly 30, so that the pin 450 can move the on-off assembly 30 and avoid the pin 450 from getting stuck on the on-off assembly 30.

[0091] In this embodiment, when the pin 450 is in the first position of the switch assembly 30, the switch is on, and when the pin 450 is in the second position of the switch assembly 30, the switch is off. Before the pin 450 moves to the first position or the second position, the first end of the transition member 420 can contact the switch assembly 30.

[0092] For example, when the switch is on, the ball 450 is in the first position. At this time, if you want to turn off the switch, that is, to toggle the button, the transition piece 420 swings, and the ball 450 moves from the first position to the second position. Before the ball 450 moves to the second position, the first end of the transition piece 420 first contacts the on-off assembly 30, thereby applying force to the on-off assembly 30, causing the on-off assembly 30 to start swinging. Since there is a hard contact between the first end of the transition piece 420 and the on-off assembly 30, a stronger toggling force can be provided, thereby preventing the on-off assembly 30 from being unable to swing normally due to the adhesion of its own silver points. The process of the ball 450 moving from the second position to the first position is similar to the above process and will not be repeated here.

[0093] Continue to see Figure 4 In this embodiment, the outer wall of the transition piece 420 has a rib 423, which extends along the length direction of the transition piece 420, and at least part of the rib 423 is located at the first end of the transition piece 420, and the rib 423 can contact the on-off assembly 30.

[0094] In the above implementation, the first end of the transition piece 420 contacts the on-off assembly 30 through the rib 423, which can reduce the contact area between the transition piece 420 and the on-off assembly 30, thereby reducing the friction between the transition piece 420 and the on-off assembly 30, and thus avoiding jamming between the transition piece 420 and the on-off assembly 30.

[0095] For example, there are two abutment ribs 423, which are arranged parallel to each other and spaced apart. This design can improve the stability of the abutment ribs 423 exerting force on the switch assembly 30, and avoid the problem of the switch assembly 30 being skewed.

[0096] In this embodiment, the lever assembly 40 further includes a handle 470 , which is connected to the second end of the lever member 430 .

[0097] In the above implementation, the handle 470 is provided at the second end of the lever 430 , which can facilitate the operation of the lever 430 and improve the convenience of the switch operation.

[0098] Illustratively, the handle 470 is a plastic structural component, which is connected to the lever component 430 by injection molding.

[0099] Exemplarily, the handle 470 , the lever 430 , and the transition piece 420 are integrally injection molded.
