The base is provided with a groove, and the sliding bar is correspondingly arranged in the groove. The side of the sliding bar opposite to the bottom surface of the base is a concave surface, and the concave surface includes a plurality of gears, and the needle roller can roll and stay in the gear. A blind hole for accommodating the elastic member is provided at one end of the rocker arm, and a first clamping groove and a second clamping groove are also provided at one end of the rocker arm provided with the blind hole, and the first clamping groove and the second clamping groove are perpendicular to each other on the end surface of the rocker arm, and the axial direction of the blind hole passes through the intersection of the first clamping groove and the second clamping groove.

The rotation of the magnetic block will cause the magnetic field of the magnetic block around the Hall element to change, and then generate Hall voltage, transmit corresponding electrical signals, and thus generate a corresponding state. When the rocker arm rotates, it will drive the needle roller arranged in the second slot to roll on the concave surface of the sliding bar. Because there are multiple gear positions on the concave surface, when the needle roller rolls to the corresponding gear position, the needle roller can stay in the gear position. At this time, the magnetic block generates a magnetic field with a magnetic induction intensity around the Hall element, and the corresponding Hall voltage will output a corresponding electrical signal. When the rocker arm is continued to be toggled, when the needle roller rolls to the next gear position, the magnetic block will generate another magnetic field with a different magnetic induction intensity around the Hall element, thereby realizing the corresponding output of another electrical signal. By moving the slider to different positions, the Hall effect is used to convert the change in magnetic field intensity into a corresponding electrical signal, thereby outputting a corresponding electrical signal. By setting multiple positions on the sliding bar, the problem of limited number of switch positions is solved. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In one aspect of the embodiment of the present invention, referring to Figure 1, a switch device 150 for realizing different working states is provided, including: a base 100, a sliding bar 101, a needle roller 104, an elastic member 103, a rocker arm 102, a first rotating shaft 105, a second rotating shaft 106, a magnetic block, and a Hall element 107. The base 100 is provided with a groove for accommodating the sliding bar 101. The side of the sliding bar 101 opposite to the bottom surface of the base 100 is a concave surface, and the concave surface includes a plurality of gears, and the needle roller 104 can roll and stay in the gear. A blind hole for accommodating the elastic member 103 is provided at one end of the rocker arm 102, and a first card slot and a second card slot are also provided at the end of the rocker arm 102 where the blind hole is provided. The first card slot and the second card slot are perpendicular to each other at the end surface of the rocker arm 102, and the axial direction of the blind hole passes through the intersection of the first card slot and the second card slot. The first card slot is used to accommodate the sliding bar 101, and the needle roller 104 is rotatably provided in the second card slot. The elastic member 103 is in a compressed state and abuts against the needle roller 104. A first rotating shaft 105 and a second rotating shaft 106 are respectively arranged on two side surfaces of the rocker arm 102, and the two side surfaces are adjacent to the extension direction of the second card slot, and the first rotating shaft 105 and the second rotating shaft 106 are arranged coaxially. The rocker arm 102 is rotatably connected to the base 100 through the first rotating shaft 105 and the second rotating shaft 106. The rocker arm 102 rotates along the extension direction of the first card slot, driving the needle roller 104 to roll to the corresponding gear position. The magnetic block is fixedly arranged at one end of the first rotating shaft 105. The Hall element 107 is arranged on the base 100, and the setting position of the Hall element 107 corresponds to the magnetic block.

[0033] Specifically, refer to Figure 1 A groove is provided on one side of the base 100, and the sliding bar 101 is provided in the groove. The concave surface of the sliding bar 101 also has corresponding multiple gears, and the needle roller 104 can roll and stay in any of the gears. A blind hole is provided at one end of the rocker arm 102, and a first card slot and a second card slot are provided at the end of the rocker arm 102 where the blind hole is provided, respectively. The first card slot and the second card slot are perpendicular to each other at the end surface of the rocker arm 102 where the blind hole is provided, and the axial direction of the blind hole passes through the intersection of the first card slot and the second card slot. The elastic member 103 is provided in the blind hole, and the first card slot accommodates the concave surface of the sliding bar 101, and the second card slot accommodates the needle roller 104. The needle roller 104 can rotate in the second card slot, as shown in FIG. Figure 1As shown, after the needle roller 104 is set in the second slot, the rolling surface of the needle roller 104 and the second slot only contact each other and are not restricted by the connecting member. After the needle roller 104 is set in the second slot, the rolling surface of the needle roller 104 and the elastic member 103 also only contact each other and have no connection relationship. At this time, the elastic member 103 is in a compressed state and abuts against the needle roller 104. The first rotating shaft 105 and the second rotating shaft 106 are respectively arranged on the two side surfaces of the rocker arm 102. The two side surfaces intersect with the extension direction of the second slot. The rocker arm 102 is rotatably connected to the base 100 through the first rotating shaft 105 and the second rotating shaft 106. In order to ensure that the rocker arm 102 can rotate relative to the base 100, the first rotating shaft 105 and the second rotating shaft 106 need to be coaxially arranged, and the rotation direction of the rocker arm 102 is the same as the extension direction of the first slot. The magnetic block is fixedly arranged at one end of the first rotating shaft 105. The Hall element 107 is arranged on the base 100, and the setting position of the Hall element 107 corresponds to the magnetic block.

[0034] By toggling the rocker arm 102, the magnetic block arranged on the first rotating shaft 105 rotates with the rotation of the first rotating shaft 105. The rotation of the magnetic block will change the magnetic induction intensity of the magnetic field around the Hall element 107, thereby generating a Hall voltage, transmitting a corresponding electrical signal, and thus generating a corresponding state. When the rocker arm 102 rotates, it will drive the needle roller 104 arranged in the second slot to roll on the concave surface of the sliding bar 101. Because a plurality of gears can also be arranged on the concave surface, when the needle roller 104 rolls to any corresponding gear, the needle roller 104 can stay at the gear. At this time, the magnetic block generates a magnetic field with a magnetic induction intensity around the Hall element 107, and the corresponding Hall voltage will output a corresponding electrical signal. When the rocker arm 102 is continuously toggled and the needle roller 104 rolls to the next gear, the magnetic block will generate another magnetic field with a different magnetic induction intensity around the Hall element 107, thereby realizing the corresponding output of another electrical signal. By moving to different gears as described above, the change in the magnetic field magnetic induction intensity is converted into a corresponding electrical signal through the Hall effect, thereby outputting a corresponding electrical signal. By setting multiple gears on the sliding bar 101, the roller needle 104 is placed in different gears while the rocker arm 102 is fluctuating, thereby solving the problem of limited number of switch gears.

[0035] Optionally, a plurality of strip grooves 1201 are provided on the concave surface of the sliding bar 101 along the extension direction of the second slot, and the extension directions of the plurality of strip grooves 1201 are parallel to each other. The strip grooves 1201 constitute a gear position, and the roller needle 104 can be rolled and limited in the strip groove 1201 .

[0036] Specifically, a plurality of strip grooves 1201 are provided on the concave surface of the sliding bar 101, the extension direction of the strip grooves 1201 is the same as the extension direction of the second slot, and the plurality of strip grooves 1201 are parallel to each other. The plurality of strip grooves 1201 constitute a plurality of corresponding gear positions, and the sliding bar 101 is a self-locking sliding bar 101. Figure 2 Take the three-position self-locking sliding bar 101 as an example, in which the middle bottom bar groove 1201 is the initial bar groove 1201, and the roller needle 104 is initially accommodated in the initial bar groove 1201. When the rocker arm 102 is toggled, the rocker arm 102 drives the roller needle 104 from the initial bar groove 1201 to roll along the concave surface to the gear position groove. At this time, the external force is removed, and the spring is compressed, pressing the roller needle 104 into the gear position bar groove 1201, preventing the roller needle 104 from rolling back to the initial bar groove 1201, thereby realizing the self-locking function. Due to the self-locking function, the state after toggling can be maintained unchanged, thereby achieving more precise control.

[0037] It should be noted that, first, the embodiment of the present invention does not limit the number of gears of the self-locking sliding bar 101. Figure 2 Only the case when there are three gear positions is illustrated, that is, the number of gear positions of the self-locking sliding bar 101 can also be four, five, six, etc. This description is also applicable to the subsequent stepless self-resetting sliding bar 101 and the self-resetting sliding bar 101 with gear positions, and will not be repeated later.

[0038] Second, the embodiment of the present invention does not impose any specific restrictions on the arrangement of the gears of the self-locking sliding bar 101. For example, the gears may be evenly distributed along the concave surface, or may be arranged at unequal intervals along the concave surface.

[0039] Optionally, the concave surface of the sliding bar 101 includes an initial surface and a gear surface that forms an angle with the initial surface, the gear surface includes a plurality of gear surfaces, and the initial surface and the gear surface correspond to gears respectively.

[0040] Specifically, the sliding bar 101 has a concave surface including an initial surface and a gear surface with different angles to the initial surface, and the gear surface includes a plurality of gear surfaces.

[0041] Solution 1: When each gear surface and the initial surface have the same angle and multiple gear surfaces are connected in sequence, the sliding bar 101 is a stepless self-reset sliding bar 101. When the rocker arm 102 is toggled to drive the roller needle 104 to be located at any gear surface, a magnetic field with a magnetic induction intensity will be generated around the Hall element 107, thereby outputting an electrical signal. After the toggling force is removed, the roller needle 104 automatically rolls back to the initial surface. This setting method can provide multiple gears for status output, and can automatically fall back to the initial surface when the status does not need to be maintained, simplifying the control operation and improving convenience.

[0042] Solution 2: When each gear position surface and the initial surface are at different angles and multiple gear positions are connected to each other in sequence, the sliding bar 101 is a self-resetting sliding bar 101 with gear positions. When the rocker arm 102 is turned to drive the roller needle 104 to be located at any gear position surface, a corresponding electrical signal is output. After the turning force is removed, the roller needle 104 automatically rolls back to the initial surface. Moreover, when the rocker arm 102 is turned to switch the gear position, there will be obvious shifting boundaries and indications. This setting method can provide multiple gear positions, and there are obvious boundaries and mechanical feedback when switching gear positions. There is more direct feedback when shifting gears, making the shifting more precise.

[0043] Solution 3: When each gear surface and the initial surface form a certain angle and the multiple gear surfaces are not connected to each other, the sliding bar 101 at this time is a self-resetting sliding bar 101 with gears. Figure 3 , is a three-gear self-reset slide bar 101, wherein the middle surface is a self-reset initial surface 1211, and the two sides are self-reset gear surfaces 1212. The self-reset initial surface 1211 and the self-reset gear surfaces 1212 are not directly connected, but are connected to each other through a transition surface provided by a concave surface. Adding a transition surface can effectively prevent operation errors caused by accidental touches.

[0044] Optional, see Figure 4 The concave surface of the sliding bar 101 includes an initial surface and an arcuate surface connected to the initial surface, and the initial surface and the arcuate surface correspond to multiple gears.

[0045] For example, refer to Figure 4 The concave surface of the slide bar 101 includes a stepless self-resetting initial surface 1221 and a curved surface connected to the stepless self-resetting initial surface 1221, the curved surface is a stepless self-resetting gear position surface 1222, the stepless self-resetting initial surface 1221 and the curved surface correspond to multiple gears, and the stepless self-resetting slide bar 101. The curved surface makes the gear shifting smoother, and when performing some precise state adjustment operations, the accuracy of the operation can be further improved.

[0046] Optional, see Figure 5 The switch device 150 for realizing different working states further includes a circuit board 108 , which is disposed on the base 100 and is located near the first rotating shaft 105 where the magnetic block is disposed, and the Hall element 107 is disposed on one side of the circuit board 108 near the base 100 .

[0047] Specifically, refer to Figure 5 The Hall element 107 is integrated on a circuit board 108 , and the circuit board 108 is disposed on the base 100 , which can save the volume of the switch and facilitate the output of the electrical signal of the Hall element 107 .

[0048] Further, see Figure 5 The switch device 150 for realizing different working states further includes a shielding side cover 109 and a shielding sleeve 110. The base 100 is connected to the first rotating shaft 105 and the second rotating shaft 106 through the first through hole and the second through hole. The shielding side cover 109 is arranged on the other side of the circuit board 108, and the shielding side cover 109 corresponds to the opening position of the first through hole, and the shielding sleeve 110 is sleeved on the outer wall of the first through hole along the axial direction of the first through hole.

[0049] For example, refer to Figure 5 , the first rotating shaft 105 is connected to the base 100 through the first through hole, at this time the magnetic block is located in the first through hole, the shielding side cover 109 and the Hall element 107 are respectively arranged on both sides of the circuit board 108, and are arranged oppositely, that is, the shielding side cover 109 is arranged on the outer side of the circuit board 108 relative to the first through hole, and corresponds to the position of the first through hole, and the shielding sleeve 110 is sleeved axially in the first through hole, and the shielding sleeve 110 is located on the outer wall of the first through hole. The magnetic block is effectively prevented from interfering with the action of the switch device 150 that realizes different working states in the embodiment of the present invention, thereby preventing action disorder.

[0050] Optional, see Figure 5 The switch device 150 for realizing different working states also includes a handle sleeved on the end of the rocker arm 102 away from the blind hole opening, and the handle includes an upper handle 113 and a lower handle 112. Both ends of the lower handle 112 are provided with a first opening and a second opening, and the second opening is used to pass the rocker arm 102, and the upper handle 113 covers the first opening by snapping. The end of the upper handle 113 away from the first opening is a curved surface for fitting a finger.

[0051] For example, refer to Figure 5 A handle is provided at one end of the rocker arm 102 away from the blind hole opening, including an upper handle 113 and a lower handle 112, and a first opening and a second opening are provided at both ends of the lower handle 112. Figure 6 , the second opening can pass through the rocker arm 102, and then be sleeved on the rocker arm 102, the upper handle 113 and the lower handle 112 are covered together in the form of a buckle, so that one end of the rocker arm 102 is completely accommodated in the cavity formed by the handle. The above connection method can be conveniently and quickly disassembled, improve the convenience of later maintenance, and reduce the cost of use. In order to improve the comfort of use, the end of the upper handle 113 away from the first opening is set as a curved surface, which better fits the shape of the user's fingers.

[0052] Optional, see Figure 5The switch device 150 for realizing different working states also includes a shell 111 sleeved on the outer wall of the base 100, and a third opening is provided on the side of the shell 111 away from the bottom of the base 100 for passing the rocker arm 102. A fourth opening corresponding to the bottom of the base 100 is provided at the bottom of the shell 111 for inserting the base 100.

[0053] For example, in order to better protect the switch device 150 in different working states in the embodiment of the present invention, a shell 111 is further provided on the outer wall of the base 100, the bottom of the shell 111 is a fourth opening, and the top of the shell 111 is provided with a third opening. After the rocker arm 102 is connected to the base 100, refer to Figure 6 The rocker arm 102 passes through the third opening on the shell 111 , the shell 111 is sleeved on the outer wall of the entire base 100 , and the fourth opening corresponds to the bottom surface of the base 100 .

[0054] Furthermore, a sealing gasket 114 is disposed at the bottom of the base 100 , and the sealing gasket 114 is used to seal the fourth opening.

[0055] For example, refer to Figure 5 A sealing gasket 114 is provided at the bottom of the base 100, and the sealing gasket 114 seals the fourth opening. The outer wall of the switch device 150 for realizing different working states in the embodiment of the present invention is provided with a handle and a shell 111. On the basis of protecting the switch device 150 for realizing different working states in the embodiment of the present invention, the sealing gasket 114 can further improve the sealing of the switch device 150 for realizing different working states in the embodiment of the present invention, thereby improving its waterproofness and extending the working life of the switch device 150 for realizing different working states in the embodiment of the present invention.

[0056] Optional, see Figure 5 The base 100 includes a base body 1001 and a side cover plate 1002 , and the side cover plate 1002 at least covers a side of the groove away from the Hall element 107 .

[0057] For example, in order to meet different usage requirements, different sliding bars 101 need to be frequently replaced, so as to achieve more complex application scenarios and reduce the cost of use.
