Description

Technical Field

[0001] The present invention belongs to the field of electronic technology, and in particular relates to a switch. Background Art

[0002] A switch is a common electrical component, which is widely used in electrical systems to switch circuits on and off.

[0003] In the related art, the switch mainly includes a housing, a button, a swing assembly and a seesaw. The button is pivotally connected to the housing and can swing relative to the housing. One end of the swing assembly is connected to the button and the other end is in contact with the seesaw. When the user presses the button, the button drives the swing assembly to swing together, so that the swing assembly moves the seesaw, and the seesaw swings synchronously to turn the switch on or off.

[0004] However, since the rotation axis of the swing assembly is the same as that of the button, the swing amplitude of the button is the same as that of the swing assembly. In order to ensure that the swing amplitude of the swing assembly is sufficient to move the rocker to the right position, the swing amplitude of the swing assembly needs to be larger, which results in a larger swing amplitude of the button, so that the user has to press a large stroke, resulting in a bad hand feel and experience for the user, and is not conducive to the compact design of the switch.

DETAILED DESCRIPTION

[0046] 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.

[0047] The present disclosure provides a switch. Figure 1 For an exploded view of the switch, see Figure 1 The switch includes a housing 10 , a button 20 , a rocker 30 and a swing assembly 40 .

[0048] The button 20 is pivotally connected to the housing 10 or the swing assembly 40. The rocker 30 is located in the housing 10 and can swing relative to the housing 10. The swing assembly 40 is located between the button 20 and the rocker 30. The first end of the swing assembly 40 faces the button 20. The second end of the swing assembly 40 abuts against the rocker 30. The swing assembly 40 is pivotally connected to the housing 10. The pivot axis L1 of the swing assembly 40 is located between the pivot axis L2 of the button 20 and the swing axis L3 of the rocker 30 (see FIG. Figure 2 , where the dotted circle is the swing trajectory of the swing component 40, the dotted circle is the swing trajectory of the button, and the dotted straight lines are the horizontal reference line and the vertical reference line). The swing component 40 is configured to, under the drive of the button 20, move the rocker 30 to swing so as to turn the switch on or off.

[0049] When the switch provided by the embodiment of the present disclosure is used to turn the electrical system on and off, the user presses the button 20 to make the button 20 swing relative to the housing 10, thereby driving the swing assembly 40 to swing together, and then driving the seesaw 30 to swing together. During the swinging of the seesaw 30, the switch can be turned on or off, thereby turning the electrical system on and off.

[0050] In the process of switching the electrical system on and off by the switch provided by the embodiment of the present disclosure, since the pivot axis of the swing assembly 40 is located between the pivot axis of the button 20 and the swing axis of the rocker 30, the pivot axis of the swing assembly 40 is closer to the rocker 30 than the pivot axis of the button 20, so that the swing amplitude of the swing assembly 40 will be greater than the swing amplitude of the button 20, thereby reducing the swing amplitude of the button 20 while ensuring that the swing amplitude of the swing assembly 40 remains unchanged. In this way, not only the hand feeling of the user when pressing the button 20 is improved, but also the space required for the button 20 to swing is reduced, which is conducive to the compact design of the switch.

[0051] In this embodiment, the switch is a two-stage transmission, the first stage of which is the transmission between the button 20 and the swing assembly 40, and the second stage of which is the transmission between the swing assembly 40 and the rocker 30. Compared with the three-stage transmission in the related art (the swing assembly itself also has a one-stage transmission relationship), the two-stage transmission has a more compact structure, less force loss during the transmission process, and is less likely to cause the problem of inaccurate dialing angle due to design tolerance.

[0052] Figure 3 is a schematic diagram of the structure of the swing assembly 40, combined with Figure 3 In this embodiment, the swing assembly 40 includes a transition piece, which includes a lever 410 and a swing arm 420. The first end of the swing arm 420 is connected to the portion between the two ends of the lever 410, and the second end of the swing arm 420 faces the rocker 30. Both ends of the lever 410 have a pressure-bearing portion 430, and the pressure-bearing portion 430 faces the button 20.

[0053] In the above implementation, the portion between the two ends of the lever 410 is pivotally connected to the housing 10, and the two ends of the lever 410 have pressure-bearing portions 430, which are used to withstand the pressure from the button 20, so that the lever 410 can swing around its own pivot axis. Since the swing arm 420 is connected to the lever 410, the second end of the swing arm 420 will swing with the lever 410, thereby driving the rocker 30 to swing.

[0054] Since the pressure-bearing portion 430 is located at the end of the lever 410, when the button 20 applies pressure to the lever 410, the force point of the lever 410 is located at the end of the lever 410. In this way, the lever 410 can be as large as possible when swinging, so that the button 20 is more labor-saving.

[0055] Exemplarily, the lever 410 and the swing arm 420 are an integrated structural component, which can not only ensure the structural strength of the lever 410 and the swing arm 420, making the force transmission more reliable, but also improve the assembly efficiency and reduce the manufacturing cost.

[0056] Furthermore, by integrating the lever 410 and the swing arm 420 into an integrated structure, design losses caused by tolerance and assembly clearance can be avoided, making the design data of the switch more accurate and the risks more controllable.

[0057] Figure 4 is a schematic diagram of the structure of the button 20, combined with Figure 4 In this embodiment, the button 20 has a pressure member 210 on one side facing the swing assembly 40 , and the pressure member 210 corresponds to the pressure receiving portion 430 one by one, and the pressure member 210 is opposite to the corresponding pressure receiving portion 430 .

[0058] When the button 20 is pressed, the pressure-applying member 210 moves toward the corresponding pressure-bearing portion 430 , and then contacts the pressure-bearing portion 430 , thereby pushing the swing assembly 40 to swing.

[0059] In the above implementation, by providing the pressure member 210 , the distance between the button 20 and the swing assembly 40 can be reduced, thereby shortening the swing stroke required for the button 20 to touch the swing assembly 40 , which is beneficial to reducing the swing amplitude of the button 20 .

[0060] See again Figure 3 , illustratively, the pressure-bearing portion 430 is located on a side of the lever 410 facing away from the swing arm 420 , and the pressure-bearing portion 430 protrudes toward the button 20 .

[0061] In the above implementation, by protruding the pressure-bearing portion 430 toward the button 20 , the distance between the button 20 and the swing assembly 40 can be further reduced, thereby shortening the swing stroke required for the button 20 to touch the swing assembly 40 , which is beneficial to reducing the swing amplitude of the button 20 .

[0062] Exemplarily, the pressure-bearing portion 430 is a long strip-shaped structural member, which is parallel to the pivot axis of the swing assembly 40. With such a design, the swing assembly 40 can more stably withstand the pressure applied by the button 20. In addition, the side of the pressure-bearing portion 430 facing the button 20 is an arc surface, which can abut against the pressure-applying member 210, thereby avoiding a jam between the pressure-bearing portion 430 and the pressure-applying member 210.

[0063] In this embodiment, the lever 410 is an arc-shaped structural member, and both ends of the lever 410 are bent and extended toward the button 20 respectively.

[0064] In the above implementation, both ends of the lever 410 are bent and extended toward the button 20, so that the lever 410 becomes an arc-shaped structural member. Since the pressure-bearing portion 430 is located at the end of the lever 410, such a design can further reduce the distance between the button 20 and the swing assembly 40, thereby shortening the swing stroke required for the button 20 to touch the swing assembly 40, and further facilitating reducing the swing amplitude of the button 20.

[0065] It is worth noting that although Figure 3 The bending amplitudes of the two ends of the lever 410 shown in the figure are relatively small, but the amplitude can be adjusted according to actual needs. The larger the bending amplitude, the smaller the distance between the button 20 and the swing assembly 40. The present disclosure does not impose any limitation on this.

[0066] Figure 5 is a schematic diagram of the assembly between the swing assembly 40 and the housing 10, combined with Figure 5 In this embodiment, the portion between the two ends of the lever 410 has a recess 411. The housing 10 includes a rear seat 110 and a pressure plate 120, the pressure plate 120 is detachably covered at the opening of the rear seat 110, and the pressure plate 120 has a pivot seat assembly 121 on a side facing away from the rear seat 110, the pivot seat assembly 121 is at least partially located in the recess 411, and the pivot seat assembly 121 is pivotally connected to the lever 410.

[0067] The pressing plate 120 is sealed at the opening of the rear seat 110, and a space for accommodating various hardware such as the rocker 30 can be formed. The lever 410 is located on the side of the pressing plate 120 facing away from the rear seat 110, and the swing arm 420 passes through the pressing plate 120 to be located in the rear seat 110, thereby toggling the rocker 30 to swing. The pivot seat group 121 is arranged on the side of the pressing plate 120 facing away from the rear seat 110, that is, on the same side of the pressing plate 120 as the lever 410, which can provide a stable installation foundation for the lever 410 and realize the mutual pivot connection between the swing assembly 40 and the housing 10. Since the pivot seat group 121 is at least partially located in the recess 411, a space for accommodating the pivot seat group 121 can be provided. The portion of the lever 410 that does not have the recess 411 can be designed with a larger size, thereby ensuring the structural strength of the lever 410. Such a design of the lever 410 not only allows accommodation space for the pivot seat assembly 121 , but also ensures its own structural strength.

[0068] It is worth noting that one swing assembly 40 corresponds to one pivot seat group 121, and one pivot seat group 121 includes two spaced-apart pivot seats, and the lever 410 is located in the gap between the two pivot seats. The two pivot seats are respectively located on both sides of the swing assembly 40 and are pivotally connected to the swing assembly 40 together, thereby effectively improving the swing stability of the swing assembly 40.

[0069] It is worth noting that in this embodiment, the pivot seat set 121 is at least partially located in the recess 411, which means that one of the two pivot seats of one pivot seat set 121 is located in the recess 411. Of course, if both pivot seats 121 are required to be located in the recess 411, then two recesses 411 need to be provided on the lever 410, and the two recesses 411 are respectively located on opposite sides of the lever 410, so as to accommodate different pivot seats 121 respectively.

[0070] Continue to see Figure 5 In this embodiment, a groove 412 is provided between the two ends of the lever 410, and the groove 412 and the swing arm 420 are located on the same side of the lever 410. A side of the pressure plate 120 facing away from the rear seat 110 has a reinforcing rib 122, and the reinforcing rib 122 can be accommodated in the groove 412.

[0071] In the above implementation, the reinforcing ribs 122 are provided on the pressing plate 120 , which can effectively improve the structural strength of the pressing plate 120 , thereby providing a more reliable installation foundation for the swing assembly 40 .

[0072] Exemplarily, the lever 410 has two grooves 412, one groove 412 is close to one pressure-bearing portion 430, and the other groove 412 is close to the other pressure-bearing portion 430. With such a design, two spaced reinforcing ribs 122 can be provided on the pressing plate 120, thereby further improving the structural strength of the pressing plate 120.

[0073] In this embodiment, if the switch is a two-open switch, the switch may include two swing assemblies 40. The two swing assemblies 40 are arranged side by side and spaced apart, and the recesses 411 of the two swing assemblies 40 are opposite to each other, and the number of the pivot seats 121 corresponds to the number of the swing assemblies 40, and the pivot seats 121 are pivotally connected to the corresponding swing assemblies 40 respectively.

[0074] Such a design of the positions of the recesses 411 of the two swing components 40 can effectively avoid interference between the two swing components 40 .

[0075] It is worth noting that if the switch is a two-way switch, then correspondingly, the button 20, the swing assembly 40, and the rocker 30 each include two. The installation methods of the two sets of buttons 20, swing assemblies 40 and rocker 30 are similar and will not be repeated here.

[0076] Figure 6 is a cross-sectional view of the swing assembly 40, combined with Figure 6In this embodiment, the swing arm 420 has a channel 421, which extends along the length direction of the swing arm 420 and passes through the second end of the swing arm 420. The swing assembly 40 also includes a pin 440 and an elastic member 450. The first end of the pin 440 is movably located in the channel 421, and the second end of the pin 440 contacts the seesaw 30. The elastic member 450 is located in the channel 421 and is connected to the swing arm 420 and the pin 440, respectively.

[0077] In the above implementation, the pin 440 is located in the channel 421 and connected to the swing arm 420 through the elastic member 450. When the pin 440 contacts the seesaw 30, the elastic member 450 is compressed, so that the pin 440 can always be in close contact with the seesaw 30 to push the seesaw 30 to swing. In addition, since the pin 440 is located in the channel 421, the outer peripheral wall of the pin 440 and the inner peripheral wall of the channel 421 slide together, so that the pin 440 can slide stably relative to the swing arm 420 to avoid unnecessary shaking.

[0078] Exemplarily, the second end of the pin 440 is conical, and the apex of the second end of the pin 440 contacts the seesaw 30 .

[0079] When the pin 440 moves the seesaw 30, the second end of the pin 440 will slide on the seesaw 30, so the second end of the pin 440 is designed to be a cone, and the apex of the cone contacts the seesaw 30, which can effectively reduce the contact area between the pin 440 and the seesaw 30, so that the pin 440 can move the seesaw 30 and avoid getting stuck on the seesaw 30.

[0080] In this embodiment, before the pin 440 drives the seesaw 30 to swing, the second end of the swing arm 420 can contact the seesaw 30. When the pin 440 is at the first position of the seesaw 30, the switch is turned on, and when the pin 440 is at the second position of the seesaw 30, the switch is turned off.

[0081] In the above implementation, the contact between the swing arm 420 and the seesaw 30 is used to forcefully drive the seesaw 30 when the seesaw 30 cannot swing normally due to the adhesion of its own silver points. Therefore, when the pin 440 moves from the first position to the second position, if the seesaw 30 does not have an adhesion problem, the pin 440 can normally drive the seesaw 30, and the second end of the swing arm 420 will not contact the seesaw 30. If the seesaw 30 has an adhesion problem, the pin 440 alone may not be able to drive the seesaw 30 normally. As the pin 440 retracts into the channel 421, the second end of the swing arm 420 contacts the seesaw 30, thereby applying force to the seesaw 30, so that the seesaw 30 begins to swing. Since the swing arm 420 and the seesaw 30 are in hard contact, a stronger pulling force can be provided, and even if the seesaw 30 has an adhesion problem, the seesaw 30 can still be forced to swing. The process of the ball 440 moving from the second position to the first position is similar to the above process and will not be described again.

[0082] It should be noted that the contact time between the second end of the swing arm 420 and the seesaw 30 is very short. After a moment of contact, the adhesion of the seesaw 30 can be released, so that the pin 440 can continue to drive the seesaw 30 to swing.

[0083] The present disclosure provides an electrical system, which includes Figures 1 to 6 Any of the switches shown.

[0084] Since the electrical system includes Figures 1 to 6 Any switch shown in the following items, so the electrical system has Figures 1 to 6 All the beneficial effects of any of the switches shown are not repeated here.
