Description

Technical Field

[0001] The utility model relates to the technical field of electric switches, in particular to an automatically reset electronic switch. Background Art

[0002] A rocker-type electronic switch is an electronic control component that allows a user to control the on / off of a circuit by rocking or pushing a rocker. This type of switch is commonly used in game controllers, remote controls, airplane joysticks, car navigation systems, and other electronic devices that require directional input.

[0003] A rocker-type electronic switch generally includes a rocker body that can be rocked in multiple directions, and a compression spring located directly below the rocker body. Further, the compression spring is coaxially arranged with the rocker body. When the rocker body is rocked back and forth, left and right, the compression spring will undergo a bending deformation deviating from the axis of the compression spring. After releasing the rocker body, the compression spring restores the deformation, thereby driving the rocker body to automatically reset to the centered state.

[0004] That is, in the existing rocker-type electronic switch, the compression spring is coaxially arranged with the rocker body, and the compression spring is mainly used to drive the rocker body to reset to the center by utilizing the anti-bending performance of the compression spring. However, the best way to apply force to the compression spring should be to squeeze the compression spring along the axis of the compression spring, so as to enable the compression spring to generate a good rebound feel.

[0005] Therefore, the existing rocker-type electronic switch has a weak rebound feel and a poor user experience.

[0006] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and thus may include information that does not form the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0007] An object of the present utility model is to provide an automatically reset electronic switch, which can effectively solve the problem of poor rebound feel of the existing rocker-type electronic switch.

[0008] To achieve the above object, the present utility model provides an automatically reset electronic switch, including:

[0009] A housing assembly, the housing assembly is provided with an accommodation cavity, and the cavity wall of the accommodation cavity is provided with a pointed-angle groove with the apex facing outward;

[0010] A rocker body, the rocker body is provided with a rotating shaft portion rotatably connected to the housing assembly, and a transverse extension rod extending from the rotating shaft portion towards the pointed-angle groove;

[0012] Optionally, the housing assembly includes:

[0013] A switch top cover provided with an upper half cavity with an opening facing downwards;

[0014] A switch base provided with a lower half cavity with an opening facing upwards;

[0015] Wherein, the switch top cover is arranged above the switch base, such that the upper half cavity and the lower half cavity are combined to form the accommodation cavity.

[0016] Optionally, the opening position of the upper half cavity is provided with an upper inclined groove wall that gradually moves away from the rocker body from top to bottom;

[0017] The opening position of the lower half cavity is provided with a lower inclined groove wall that gradually approaches the rocker body from top to bottom;

[0018] The upper inclined groove wall and the lower inclined groove wall are combined to form the pointed corner groove.

[0019] Optionally, the spring steel ball assembly includes a compression spring and a rolling steel ball located on one side of the compression spring away from the rotating shaft portion and driven by the compression spring to abut against the pointed corner groove.

[0020] Optionally, the outer surface of the rotating shaft portion is provided with a spherical structure, and the switch top cover and the switch base are provided with spherical grooves adapted to the spherical structure.

[0021] Optionally, the number of the spring steel ball assemblies is two, and the two spring steel ball assemblies are symmetrically arranged with respect to the rotating shaft portion;

[0022] The rocker body is provided with a square portion, and the switch top cover is provided with a long strip groove for the square portion to reciprocally rock along the vertical plane where the spring steel ball assembly is located.

[0023] Optionally, the number of the spring steel ball assemblies is four, wherein two of the spring steel ball assemblies are symmetrically arranged with respect to the rotating shaft portion along a first direction, and the other two spring steel ball assemblies are symmetrically arranged with respect to the rotating shaft portion along a second direction; wherein, the first direction is perpendicular to the second direction;

[0024] The rocker body is provided with a square portion, and the switch top cover is provided with a cross groove for the square portion to reciprocally rock in the plane where the first direction is located and in the plane where the second direction is located.

[0025] Optionally, it further includes:

[0026] A plurality of conductive pins, one end of each conductive pin extends through the switch base to the lower side of the transverse extension rod to form a power connection part; the other end of each conductive pin is located outside the switch base to form a pin part;

[0027] A metal conductive sheet, the metal conductive sheet is located between the transverse extension rod and each of the power connection parts. Wherein, a conductive elastic sheet is provided at a position corresponding to the upper side of every two adjacent power connection parts;

[0028] Wherein, when the conductive elastic sheet is pressed downward by the transverse extension rod, it conducts the power connection state of the corresponding two power connection parts, and when it is not pressed downward by the transverse extension rod, it disconnects from the two power connection parts to be in a power-off state.

At this time, the rocker body is in a centered state;

[0032] When the rocker body is shaken, the transverse extension rod tilts relative to the sharp-angle groove and drives the spring steel ball assembly to slide to the inclined groove wall away from the vertex angle. At this time, the state of the rocker body is unstable. Once the rocker body is released, the spring steel ball assembly will slide along the inclined groove wall and reset to the position closest to the vertex angle again, thereby completing the centered reset of the rocker.

[0033] In the above process, the spring steel ball assembly is mainly subjected to the extrusion force applied by the sharp-angle groove along the axis of the spring steel ball assembly. Therefore, when the spring steel ball assembly recovers from the compressive deformation, it can provide a relatively large elastic force to the rocker body, so that the rocker body has a good rebound feel when reset.

[0034] Therefore, the automatic reset electronic switch provided by the present utility model can effectively solve the problem of poor rebound feel of the existing rocker-type electronic switch. Description of the Drawings

[0054] The present utility model provides an automatic reset electronic switch, which is applicable to application scenarios with rocker control and can effectively solve the problem of poor rebound feel of existing rocker-type electronic switches.

[0055] See Figure 1 , the automatic reset electronic switch provided in this embodiment includes a housing assembly 1, a rocker body 2, and a spring steel ball assembly 3. Among them, the housing assembly 1 is provided with a receiving cavity, and the cavity wall of the receiving cavity is provided with a sharp corner groove 103 with a sharp corner 1031 facing outward. The rocker body 2 is provided with a rotating shaft portion 201 rotatably connected to the housing assembly 1 and a transverse extension rod 202 extending from the rotating shaft portion 201 toward the sharp corner groove 103. The first end of the spring steel ball assembly 3 is installed in the transverse extension rod 202, and the other end abuts against the sharp corner groove 103.

[0056] For the automatic reset electronic switch provided by the present utility model, when the rocker body 2 is not shaken, under the guiding action of the sharp corner groove 103, the spring steel ball assembly 3 automatically slides to the position closest to the sharp corner 1031 of the sharp corner groove 103. At this time, the rocker body 2 is in a centered state;

[0057] When the rocker body 2 is shaken, the transverse extension rod 202 is inclined relative to the sharp corner groove 103 and drives the spring steel ball assembly 3 to slide to the inclined groove wall away from the sharp corner 1031. At this time, the state of the rocker body 2 is unstable. Once the rocker body 2 is released, the spring steel ball assembly 3 will slide along the inclined groove wall and reset to the position closest to the sharp corner 1031 again, thereby completing the centered reset of the rocker.

[0058] In the above process, the spring steel ball assembly 3 is mainly subjected to the extrusion force applied by the sharp corner groove 103 along the axis of the spring steel ball assembly 3. Therefore, when the spring steel ball assembly 3 recovers from the compression deformation, it can provide a large elastic force to the rocker body 2, so that the rocker body 2 has a good rebound feel when resetting.

[0059] Therefore, the automatic reset electronic switch provided by the present utility model can effectively solve the problem of poor rebound feel of the existing rocker-type electronic switch.

[0060] In this embodiment, the housing assembly 1 includes a switch top cover 101 and a switch base 102. The switch top cover 101 is provided with an upper half cavity 1011 with an opening facing downwards; the switch base 102 is provided with a lower half cavity 1021 with an opening facing upwards; wherein, the switch top cover 101 is arranged above the switch base 102, so that the upper half cavity 1011 and the lower half cavity 1021 are combined to form the accommodation cavity. Optionally, the switch top cover 101 and the switch base 102 are snap-connected, which is convenient for installation and disassembly.

[0061] Further, at the opening position of the upper half cavity 1011, there is an upper inclined groove wall 1012 that gradually moves away from the rocker body 2 from top to bottom; at the opening position of the lower half cavity 1021, there is a lower inclined groove wall 1022 that gradually approaches the rocker body 2 from top to bottom; the upper inclined groove wall 1012 and the lower inclined groove wall 1022 are combined to form the pointed angle groove 103.

[0062] In this embodiment, the spring steel ball assembly 3 includes a compression spring 301 and a rolling steel ball 302 that is located on the side of the compression spring 301 away from the rotating shaft portion 201 and is driven by the compression spring 301 to abut against the pointed angle groove 103.

[0063] Driven by the compression spring 301, the rolling steel ball 302 will move downward along the upper inclined groove wall 1012 and upward along the lower inclined groove wall 1022. Therefore, as long as the rocker body 2 is pushed so that the rolling steel ball 302 moves away from the vertex angle 1031 of the pointed angle groove 103, the spring steel ball assembly 3 will generate a relatively large elastic potential energy for driving the rocker body 2 to return to the center. Once the rocker body 2 is released, the elastic potential energy can be released, thereby completing the centering reset of the rocker body 2.

[0064] In this embodiment, the outer surface of the rotating shaft portion 201 is provided with a spherical structure, and the switch top cover 101 and the switch base 102 are provided with spherical grooves 1023 that are adapted to the spherical structure. The cooperation of the spherical structure and the spherical grooves 1023 enables the rocker body 2 to rotate relative to the housing assembly 1 in all directions.

[0065] Optionally, referring to Figure 2 , the automatic reset electronic switch is a two-way switch. At this time: the number of the spring steel ball assemblies 3 is two, and the two spring steel ball assemblies 3 are symmetrically arranged with respect to the rotating shaft portion 201; the rocker body 2 is provided with a square portion 203, and the switch top cover 101 is provided with a long strip groove 1013 for the square portion 203 to swing reciprocally along the vertical plane where the spring steel ball assembly 3 is located.

[0066] The two spring ball assemblies 3 can achieve rocking in two directions, front and back (or left and right). The long slot 1013 only provides a large rocking space in one direction (for example, the front-back direction), and the gap between the long slot 1013 and the square portion 203 in the other direction (for example, the left-right direction) is small, which is not sufficient for the rocker body 2 to rock. The cooperation between the square portion 203 and the long slot 1013 enables the rocker body 2 to perform two-way rocking only on the vertical plane where the spring ball assembly 3 is located, so that the spring ball assembly 3 can drive the rocker body 2 to reset to the center.

[0067] Or, referring to Figure 3 , the automatic reset electronic switch is a four-way switch. At this time: the number of the spring ball assemblies 3 is four, two of the spring ball assemblies 3 are symmetrically arranged about the rotating shaft portion 201 along a first direction, and the other two spring ball assemblies 3 are symmetrically arranged about the rotating shaft portion 201 along a second direction; wherein, the first direction is perpendicular to the second direction; the rocker body 2 is provided with a square portion 203, and the switch top cover 101 is provided with a cross slot 1014 for the square portion 203 to reciprocally rock in the plane where the first direction is located and in the plane where the second direction is located. The cooperation between the cross slot 1014 and the square portion 203 can enable the rocker body 2 to perform four-way rocking in the front, back, left, and right directions.

[0068] In this embodiment, the automatic reset electronic switch further includes a metal conductive sheet 4 and a plurality of conductive pins 5.

[0069] One end of the conductive pin 5 extends below the transverse extension rod 202 through the switch base 102 to form a power connection portion 501; the other end of the conductive pin 5 is located outside the switch base 102 to form a pin portion 502. The metal conductive sheet 4 is located between the transverse extension rod 202 and each of the power connection portions 501, and a conductive elastic sheet 401 is provided at a position corresponding to the upper part of every two adjacent power connection portions 501.

[0070] Wherein, the conductive elastic sheet 401 has a power connection state of conducting the corresponding two power connection portions 501 when being pressed downward by the transverse extension rod 202, and has a power-off state of disengaging from the two power connection portions 501 when not being pressed downward by the transverse extension rod 202.

[0071] Further, a pressing boss 2021 for pressing the conductive elastic sheet 401 downward is provided at the bottom of the transverse extension rod 202.

[0072] Under normal circumstances, the spring steel ball assembly 3 drives the rocker body 2 to be in the centered position, and the pressing boss 2021 disengages from the conductive elastic sheet 401. Since the conductive elastic sheet 401 does not receive the downward pressure from the pressing boss 2021, it disengages from the corresponding two power connection parts 501, and the two power connection parts 501 are in an open circuit state;

[0073] When the rocker body 2 is shaken, the corresponding pressing boss 2021 inclines downward and presses the corresponding conductive elastic sheet 401. After being pressed, the conductive elastic sheet 401 bends downward and deforms, thereby conducting the adjacent two power connection parts 501. Therefore, according to the conduction state of each power connection part 501, it can be known which direction of rocker operation the user has performed.

[0074] Optionally, see Figure 2 or Figure 3 , a silica gel pad 6 is also provided above the metal conductive sheet 4 to achieve insulation protection between the metal conductive sheet 4 and other components.

[0075] In summary, the automatic reset electronic switch provided in this embodiment has the following advantages:

[0076] ① Automatic reset function: Through the design of the spring steel ball assembly 3, the rocker body 2 can automatically return to the centered position after being released, without the need for manual reset by the user, improving the operation convenience.

[0077] ② Good return feel: When the spring steel ball assembly 3 recovers from the compressive deformation, it provides a relatively large elastic force to the rocker body 2, making the rocker have an obvious return feeling when reset, enhancing the user experience.

[0078] ③ Directional control: The cooperation of the spherical structure and the spherical groove 1023 enables the rocker to rotate in multiple directions, adapting to different operation habits and requirements; further, through the combination of the upper inclined groove wall 1012 and the lower inclined groove wall 1022, and the cooperation of the square part 203 and the long strip groove 1013 or the cross groove 1014, precise control of the rocker in two directions or four directions is achieved, meeting the requirements of different application scenarios;

[0079] ④ Precise circuit control: Through the design of the conductive pins 5, the metal conductive sheet 4 and the conductive elastic sheet 401, the corresponding power connection parts 501 can be conducted or disconnected according to the inclination direction and degree of the rocker, thereby precisely controlling the circuit state.

[0080] ⑤ The paired and symmetric design of the spring steel ball assembly 3 ensures the stability of the rocker during operation. Even in extreme cases, it can ensure that the rocker resets quickly and accurately.

[0081] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions generated by equivalent structure or equivalent process substitution or modification made based on the essential concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as those directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included within the patent protection scope of this application.
