As shown in fig. 2, the rocker switch provided in the embodiment of the present invention includes a supporting member 2, and a protruding shaft 21 is disposed on the supporting member 2; further comprising a rocker 3, the rocker 3 comprising a bridging portion 32 and a stop portion 33;

as shown in fig. 4 and 7, the seesaw member 3 is rotatably overlapped on the protruding shaft 21 by the overlapping portion 32, the stopping portion 33 is located below the protruding shaft 21 and fixedly connected to the overlapping portion 32, and the overlapping portion 32 and the stopping portion 33 can prevent the seesaw member 3 from moving away from the protruding shaft 21.

The embodiment of the utility model provides a seesaw switch because seesaw piece 3 rotationally overlaps on protruding axle 21 through overlap joint portion 32, like this, through overlap joint portion 32 and protruding axle 21's contact, can guarantee the electricity between seesaw piece 3 and support piece 2 when realizing the seesaw piece 3 pivoted and be connected.

Since the stop portion 33 is located below the protruding shaft 21 and is fixedly connected to the overlapping portion 33, the overlapping portion 32 and the stop portion 33 can prevent the tilting plate 3 from moving away from the protruding shaft 21. That is to say, the stopping portion 33 located below the protruding shaft 21 is provided to prevent the seesaw member 3 from jumping upwards and separating from the support member 2 during the rotation process, and the overlapping portion 32 overlapping the protruding shaft 21 also prevents the seesaw member from separating from the support member 2 downwards during the rotation process, thereby limiting the seesaw member 3.

Therefore, the embodiment of the utility model provides a rocker switch, its rocker 3 can be through the contact all the time of overlap joint portion 32 and backstop portion 33 with protruding axle 21 on the support piece 2, can avoid producing the separation electric arc between support piece 2 and the rocker 3 from this, and then can prevent that the structure of rocker switch from being ablated by electric arc and damaging, greatly increased rocker switch's life.

In order to realize the control of the rocker switch on or off the circuit, as shown in fig. 2, the rocker switch further includes an incoming terminal 4 and an outgoing terminal 5, and both the incoming terminal 4 and the outgoing terminal 5 can be communicated with the circuit wire; the incoming terminal 4 is electrically connected with the support 3, and a second contact 51 is arranged at the top of the outgoing terminal 5; the rocker member 3 further comprises a rocker body 31, wherein the end of the rocker body 31 is provided with a first contact 311, and the middle of the rocker body 31 is fixedly connected with the bridging portion 32. As shown in fig. 9, when the rocker 3 rotates to the limit position, the first contact 311 and the second contact 51 are in close contact, so that the above-mentioned cooperation prevents the rocker from rotating further, and the conduction of the circuit between the inlet terminal 4 and the outlet terminal 5 can be realized by the first contact 311 and the second contact 51 which are in contact conduction.

As shown in fig. 9, two outlet terminals 5 are respectively disposed corresponding to two ends of the rocker main body 31, the top of each outlet terminal 5 is provided with a second contact 51, and the two first contacts 311 are respectively disposed at two ends of the rocker main body 31. Therefore, the embodiment of the present invention provides a rocker switch, which can be used to switch on two different wire terminals 5 through the rotation direction of the control rocker main body 31.

With continued reference to fig. 9, the extreme positions include two different first and second extreme positions when the rocker body 31 is rotated in different directions, since the rocker body 31 is rotated in different directions to conduct two different outlet terminals 5. When the seesaw member 3 rotates clockwise to the first limit position, the first contact 311 at the right end of the seesaw main body 31 is in close contact with the second contact 51 at the right side, so that the seesaw member is prevented from rotating clockwise continuously, the circuit between the incoming line terminal 4 and the outgoing line terminal 5 at the right side can be conducted, and at the moment, the circuit between the incoming line terminal 4 and the outgoing line terminal 5 at the left side is interrupted; when the rocker plate 3 rotates counterclockwise to the second limit position, the first contact 311 at the left end of the rocker plate body 31 is in close contact with the second contact 51 at the left side, so that the rocker plate is prevented from rotating counterclockwise continuously, and meanwhile, the circuit conduction between the incoming line terminal 4 and the left outgoing line terminal 5 can be realized, obviously, the circuit between the incoming line terminal 4 and the right outgoing line terminal 5 is interrupted at this time.

For the electrical connection between the wire terminal 4 and the support 2, specifically, the wire terminal 4 and the support 2 may be electrically connected through a conductive structure such as a conductive sheet or a conductive wire; however, in the embodiment of the present invention, in order to simplify the components, as shown in fig. 8, in the present embodiment, the supporting member 2 is directly connected with the wire terminal 4 in a fixed contact manner, so that the wire terminal 4 and the supporting frame 2 can be regarded as one component, thereby reducing the number of components and simplifying the assembly process. Wherein, the inlet terminal 4 and the outlet terminal 5 are respectively provided with a fastening bolt for fixing the circuit wire.

In order to ensure a smooth rotation of the rocker member 3 about the support member 2. As shown in fig. 4 and 7, the overlapping part 32 and the blocking part 33 enclose an installation space 34, and the installation space 34 includes an overlapping space 341 and an accommodating space 342; the top of the overlapping space 341 is overlapped and abutted with the top of the protruding shaft 21, and the width of the overlapping space 341 is larger than that of the protruding shaft 21; the accommodating space 342 is located below the overlapping space 341, and the width of the accommodating space 342 gradually increases from top to bottom.

Through the setting of installation space 34, when the overlap joint portion 32 of overlap joint on protruding axle 21 rotates around protruding axle 21, overlap joint space 341 rotates around the top synchronization of protruding axle 21, and great overlap joint space 341 width makes and has clearance allowance between overlap joint space 341 and the protruding axle 21, and at wane spare 3 pivoted in-process, can avoid the condition emergence of protruding axle 21 and the mutual joint of overlap joint space 341. Meanwhile, the gradually increasing width of the accommodating space 342 from top to bottom makes the mounting space 34 have a larger rotation range, i.e., it is ensured that the seesaw member 3 can smoothly rotate around the support member 2.

Since the width of the overlapping space 341 is greater than the width of the protruding shaft 21 in the overlapping space, the cross-sectional shape of the overlapping space 341 may be any shape, such as: rectangular, trapezoidal, triangular, and the like, in any regular or irregular shape. In order to make the installation space 34 have a regular shape, as shown in fig. 4 and 7, the overlapping space 341 is provided in a rectangular shape, the upper ends of the two sidewalls 321 of the accommodating space 342 are connected to the lower ends of the two sidewalls 341 of the overlapping space in a one-to-one correspondence, the two sidewalls 321 extend downward respectively, and the distance therebetween gradually increases. Wherein the minimum width of the receiving space 342 is greater than the maximum width of the overlapping space 341.

In order to achieve a constant contact connection between the rocker 3 and the support 2. As shown in fig. 4 and fig. 7, a bottom wall of the stopping portion 33 facing the protruding shaft 21 is an arc-shaped bottom wall 331, and a circle center of the arc-shaped bottom wall 331 coincides with a rotation center of the tilting plate 3; when the paddle member 3 rotates about the top of the protruding shaft 21, the bottom of the protruding shaft 21 comes into sliding contact with the arc-shaped bottom wall 331. Because arc diapire 331 uses the rotation center of wane piece 3 to set up as the centre of a circle, so, under the condition that does not influence seesaw piece 3 pivoted, through setting up arc diapire 331 on backstop portion 33 with protruding axle 21 be located between overlap joint portion 32 and backstop portion 33 to the contact is connected all the time, can avoid producing electric arc between support piece 2 and the seesaw piece 3, prevent that the structure of seesaw switch from being ablated by electric arc and damaging, greatly increased the life of seesaw switch.

Specifically, the rotation angle of the rocker 3 from the first limit position to the second limit position is the maximum rotation angle α of the rocker 3. Wherein the corresponding mounting space 34 is schematically shown in solid lines in fig. 5 when the rocker 3 is rotated to the first extreme position; when the rocker 3 is rotated to the second extreme position, the corresponding mounting space 34 is schematically shown in dashed lines in fig. 5; as shown in fig. 5, the two accommodating spaces 342 correspond to the two mounting spaces 34, and the included angle between the two adjacent side walls 321 is the maximum rotation angle α.

With reference to fig. 5, since the width between the two opposite side walls 321 of the accommodating space 342 is gradually increased from top to bottom, and the angle between the extension lines of the two side walls 321 is β, the maximum rotation angle α of the rocker 3 is smaller than the angle β between the two opposite side walls 321 of the accommodating space 342 during the rotation of the rocker 3. Meanwhile, when the seesaw member 3 is rotated to the extreme position, there is a gap between the protruding shaft 21 and both side walls 321 of the accommodating space 342.

Because the seesaw member 3 is in the rotation process, the maximum rotation angle is smaller than the included angle between the two opposite side walls 321, and a gap is formed between the convex shaft 21 and the two side walls 321 all the time, so that a margin is left between the two side walls 321 of the accommodating space 342 and the convex shaft 21 all the time, the limitation of the accommodating space 342 on the rotation amplitude of the seesaw member 3 is avoided, and the smoothness of the rotation of the seesaw member 3 is ensured.

The cross-sectional shape of the protruding shaft 21 provided on the support 2 along the direction perpendicular to the axial direction is a polygon. The polygon may be a triangle, a rectangle, a pentagon, etc., and is not limited in particular.

It should be noted that, since the protruding shaft 21 is provided on the support 2, the cross-sectional shape of the protruding shaft 21 perpendicular to the axial direction has a fitting relationship with the structural shape of the support 2.

Wherein, to support piece 2, support piece 2 can set up to arbitrary structures such as cuboid, cylinder or triangular prism, and the homoenergetic realizes the supporting role to wane piece 3. In the embodiment of the present invention, as shown in fig. 10 and 14, the supporting member 2 is set to be a sheet structure, and compared with other structures, the supporting member 2 of the sheet structure is very simple, so that the supporting function of the seesaw member 3 is ensured, the occupied volume is very small, and a large amount of raw materials can be saved.

Because support piece 2 is set up to sheet structure, is provided with protruding axle 21 in at least one side in sheet support piece 2's both sides, this support piece 2 that is equipped with protruding axle 21 can directly be accomplished through integrated into one piece technology preparation, and structural strength is higher to production is simple, and it is very little to occupy the volume. In the actual production process, the integral forming process specifically comprises the following steps: the raw material plate is punched through the die, so that the qualified sheet-shaped supporting piece structure is directly obtained, and the large-scale production is very simple and convenient. As shown in fig. 10, 11 and 13, the sheet-shaped support 2 manufactured through the stamping process has a rectangular cross-sectional shape perpendicular to the axial direction of the protruding shaft 21, and it is very convenient to manufacture the cross-sectional shape of the protruding shaft 21 without additional processing.

In particular, the protruding shaft 21 provided on the support 2 has various assembly solutions. For example: the protruding shaft 21 is a single one, and is separately fixed on one side surface or the top surface of the supporting member 2, or the overlapping part 32 is directly overlapped on the protruding shaft 21; the protruding shafts 21 may also be provided in two, and coaxially disposed on two sides of the supporting member 2, that is, one end of each of the two protruding shafts 21 is fixedly connected to two opposite sides of the supporting member 2 one by one. As shown in fig. 14, compared with the technical solution of providing one protruding shaft 21, the two protruding shafts 21 are respectively disposed on two opposite sides of the supporting member 2, and when the tilting plate member 3 is stably supported, the two protruding shafts 21 that are respectively disposed only need to be set to a small length to meet the lap joint fixation of the two lap joint portions 32, and compared with the arrangement solution of one protruding shaft, the raw material for manufacturing the protruding shaft 21 can be greatly saved.

Since the two protruding shafts 21 are coaxially disposed at both sides of the support 2. As shown in fig. 14 and 15, correspondingly, two overlapping portions 32 on the rocker member 3 are also provided, and are respectively disposed on two sides of the rocker member 31, the two overlapping portions 32 are overlapped on the two protruding shafts 21 in a one-to-one correspondence, and a stopping portion 33 is disposed below each of the two protruding shafts 21, so that the rotatable connection of the rocker member 3 with respect to the support member 2 is more stable and reliable.

As shown in fig. 11 and 12, the bridging portion 32 is fixedly connected to the middle portion of the seesaw main body 31. The warping plate 3 is directly manufactured by an integrated forming process, and the whole structural strength of the warping plate 3 can be ensured while the processing is convenient.

In the actual production process, the primarily formed rocker 3 (excluding the first contact 311) is obtained directly from the raw material plate by an integral press-forming process, as shown in fig. 14. The final finished rocker 3 is then obtained by fixedly arranging the first contacts 311 at both ends of the rocker body 31, respectively. When the installation is carried out, because the overlapping portion 32 and the stopping portion 33 at this time have an opening included angle, the overlapping portion 32 and the protruding shaft 21 are very convenient to align, after the alignment is completed, the two overlapping portions 32 and the stopping portion 33 are clamped inwards together by a tool, so that the stopping portion 33 is arranged right below the protruding shaft 21, as shown in fig. 15, the assembly is completed at this time.

For the protruding shaft 21 arranged on the support member 2, the two support members 2 and the protruding shaft 21 can be fixedly connected in a welding manner; the fixed connection between the main body 31 and the strap 32 and between the strap 32 and the stop 33 can be achieved by welding. Compared with a processing mode of stamping through a die, the welding and fixing mode is flexible and convenient, and the method is very suitable for small-batch experimental production.

In order to make the rotational connection between the rocker 3 and the support 2 more stable, the bridge 32 and the stop 33 form a full enclosure in the circumferential direction of the protruding shaft 21, as shown in fig. 10 and 12. Through the installation space that the full enclosure structure set up, can avoid warping the unexpected condition emergence that plate 3 drops on by protruding axle 21.

In another implementation of the present invention, as shown in fig. 7, 8 and 9, the stopping portion 33 is provided with an opening 6. By providing the opening 6, it is very convenient to fit the protruding shaft 21 into the mounting space 34 through the opening 6 during the fitting process. The aperture size of the opening 6 can be slightly smaller than the width of the protruding shaft 21, and the protruding shaft 21 is assembled by extrusion during assembly, so that the protruding shaft 21 can be prevented from falling off from the mounting opening 6. In order to avoid that the opening 6 provided in the stop portion 33 affects the stable operation of the tilting plate 3 in rotation, as shown in fig. 7, the opening 6 is provided in the middle of the stop portion 33, so that the stop portions 33 located at both sides of the opening 6 can still limit the tilting plate 3 from being separated from the supporting member 2 during the rotation of the tilting plate 3.

In order to further simplify the assembly of the protruding shaft, as shown in fig. 7 and 8, the lower side of the opening 6 is expanded outward, the opening diameter of the lower side of the opening 6 is larger than the width of the protruding shaft 21, and the opening diameter of the upper side of the opening 6 is inconvenient and still smaller than the width of the protruding shaft 21. This arrangement facilitates alignment of the protruding shaft 21 with the opening 6 during installation.

Wherein, the rocker switch still includes clamp plate 1, and clamp plate 1 sets up in the top of rocker piece 3, is fixed with gag lever post 11 on clamp plate 1, and the lower extreme of gag lever post 11 is close to the intermediate position of rocker piece 3. As shown in fig. 2, 3 and 4, since the limiting rod 11 is not in direct contact with the rocker 3, the rotation of the rocker 3 is not hindered; therefore, the limiting rod 11 extending from the upper part to the middle position of the seesaw member can limit the jumping of the seesaw member 3, and the seesaw member 3 is prevented from being separated from the convex shaft 21. Particularly, this gag lever post 11 set up can with the cooperation of overlap joint portion 32 for protruding axle 21 on seesaw piece 3 and the support piece 2 contacts all the time, can avoid the production of separation electric arc between seesaw piece 3 and the support piece 2, prevents that the structure of seesaw switch from being ablated and damaged, when improving the circular telegram performance, makes the seesaw switch have better durability.

When a user operates the rocker switch control circuit, as shown in fig. 6, 8 and 16, a rotatable toggle piece 7 is further arranged in the pressure plate 1, the upper end of the toggle piece 7 is connected with a button 8, the lower end of the toggle piece 7 abuts against the middle of the rocker piece 3, and specifically, as shown in fig. 9, the lower end of the toggle piece 7 abuts against the middle of the upper surface of the rocker main body 31; through pressing button 8, can drive and dial 7 and rotate, dial 7 pivoted in-process and can stir wane main part 31 to make wane piece 3 rotate, thereby realize the operation control of wane switch.

Specifically, as shown in fig. 2 and 9, the lower end of the toggle member 7 is provided with a blind hole 71, an expansion link 72 is installed in the blind hole 71, the lower end of the expansion link 72 is disposed outside the blind hole 71 and abuts against the seesaw member 3, the upper end of the expansion link 72 is located in the blind hole 71, and a spring 73 is disposed between the upper end of the expansion link 72 and the blind hole 71. When the toggle piece 7 rotates, the lower end of the telescopic rod 72 compresses the spring 73, and relative sliding occurs with the upper surface of the rocker main body 31, the one end at the middle part of the rocker piece 3 slides to the other end, in the process, due to the elastic action of the spring 73, the lower end of the telescopic rod 72 is always attached to the rocker main body 31, and a rotating force is applied to the rocker piece 3, so that the rocker piece 3 can rotate under the driving of the toggle piece 7, and the operation control of the rocker switch is realized.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
