Description

Technical Field

[0002] At present, the switches of the rocker type on the market use a structure in which the upper and lower rocker arms drive the sliders inside the switch to perform linear motions in the X-axis direction and the Y-axis direction respectively.

[0013] As a further improvement of the present utility model, a driving rod penetrating between the lower swing linkage arc platform and the lower swing bracket is respectively formed on both sides of the rocker.

[0014] The beneficial effects of the present utility model are as follows:

[0015] This switch of the present utility model is provided to include a circuit board, a base disposed on the circuit board, a face shell disposed on the base, and a rocker arm assembly electrically connected to the circuit board. The rocker arm assembly includes a rocker penetrating out of the upper end of the face shell, an upper rocker arm rotatably disposed on the base and driven by the rocker, a lower rocker arm rotatably disposed between the base and the upper rocker arm and perpendicular to the upper rocker arm in a cross-horizontal direction and driven by the rocker, a first magnet disposed on one side of the upper rocker arm, and a second magnet disposed on one side of the lower rocker arm. A first TMR magnetic sensor chip is electrically connected to the circuit board at a position corresponding to the first magnet, and a second TMR magnetic sensor chip is electrically connected to the circuit board at a position corresponding to the second magnet.

[0016] The base and the face shell wrap part of the structure of the rocker arm assembly, thus playing a protective role to prevent external factors from affecting the normal operation of part of the structure of the rocker arm assembly. The circuit board is electrically connected to an external machine to realize power supply and signal transmission. The first TMR magnetic sensor chip and the second TMR magnetic sensor chip have the same structure and operating principle. The principle of the TMR magnetic sensor chip is to form a structure by sandwiching two magnetic layers between a non-magnetic layer. The non-magnetic layer serves as the contact of the sensor, and the magnetic layers allow current to pass through and can generate a magnetic field. When the externally applied magnetic field interacts with the magnetic field in the magnetic layer, the direction of the magnetic field changes, thereby changing the value of the magnetoresistance. The resistance value of the TMR element in the TMR magnetic sensor chip changes according to the change of the external magnetic field, so it can be used to detect the intensity and direction of the magnetic field. And the TMR magnetic sensor chip has low power consumption, with its power consumption reaching the microamp level, and has higher sensitivity. While improving the sensing accuracy of this Hall rocker switch, it effectively meets the usage requirements of precision instruments that require switches with low power consumption.

[0017] When people shake the rocker, the rocker drives the upper rocker arm and the lower rocker arm to rotate separately or simultaneously drives the upper rocker arm and the lower rocker arm to rotate simultaneously in different directions. The first magnet on the upper rocker arm is driven by the upper rocker arm to rotate between the base and the front shell. The first magnet and the first TMR magnetic sensor chip interact with each other. When the first magnet rotates, the direction and intensity of its magnetic field change, so that the first TMR magnetic sensor chip senses different output voltages. The first TMR magnetic sensor chip senses and transmits the sinusoidal change of voltage according to the change of the position of the first magnet, and cooperates with the magnetic core induction, so that the direction and amplitude of the rocker driving the upper rocker arm to shake can be obtained. At the same time, the second magnet on the lower rocker arm is driven by the lower rocker arm to rotate between the base and the front shell. The second magnet and the second TMR magnetic sensor chip interact with each other. When the second magnet rotates, the direction and intensity of its magnetic field change, so that the second TMR magnetic sensor chip senses different output voltages. The second TMR magnetic sensor chip senses and transmits the sinusoidal change of voltage according to the change of the position of the second magnet, and cooperates with the magnetic induction, so that the direction and amplitude of the rocker driving the lower rocker arm to shake can be obtained, which is beneficial to improving the sensitivity and accuracy of detecting the shake of this switch, and greatly increasing the service life and performance of this switch. And this switch avoids the problems of the stuck feeling of the slider sliding and hitting the base and the large number of transmission mechanisms caused by using the rocker to drive the slider. The structure of the upper rocker arm and the lower rocker arm being perpendicular to each other in a cross shape enables the rocker in this switch to rotate freely 360 degrees while still being able to drive the upper rocker arm and the lower rocker arm to rotate in different directions. The transmission mechanism is less, the structure is simple, the overall structural error is small, and it can drive smoothly without a stuck feeling, and the rotation feel is better, effectively ensuring people's use experience.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] Please refer to Figures 1 to 10 , the embodiment of the present utility model provides a Hall rocker 41 switch with better feel and lower power consumption, including a circuit board 1, a base 2 disposed on the circuit board 1, a face shell 3 disposed on the base 2, and a rocker arm assembly 4 electrically connected to the circuit board 1. The rocker arm assembly 4 includes a rocker 41 penetrating through the upper end of the face shell 3, an upper rocker arm 42 rotatably disposed on the base 2 and driven by the rocker 41 to penetrate, a lower rocker arm 43 rotatably disposed between the base 2 and the upper rocker arm 42 and perpendicular to the upper rocker arm 42 in a cross-horizontal direction and driven by the rocker 41 to penetrate, a first magnet 44 disposed on one side of the upper rocker arm 42, a second magnet 45 disposed on one side of the lower rocker arm 43, a first TMR magnetic sensor chip 11 electrically connected to the circuit board 1 at a position corresponding to the first magnet 44, and a second TMR magnetic sensor chip 12 electrically connected to the circuit board 1 at a position corresponding to the second magnet 45.

[0035] The base 2 and the front shell 3 wrap part of the structure of the rocker arm assembly 4, thereby playing a protective role to prevent external factors from affecting the normal operation of part of the structure of the rocker arm assembly 4. The circuit board 1 is mechanically electrically connected to the outside to achieve power supply and signal transmission. The first TMR magnetic sensor chip 11 and the second TMR magnetic sensor chip 12 have the same structure and operating principle. The principle of the TMR magnetic sensor chip is to form a structure by sandwiching two magnetic layers between a non-magnetic layer. The non-magnetic layer serves as the contact of the sensor, and the magnetic layer allows current to pass through and can generate a magnetic field. When the externally applied magnetic field interacts with the magnetic field in the magnetic layer, the direction of the magnetic field changes, thereby changing the value of the magnetoresistance. The resistance value of the TMR element in the TMR magnetic sensor chip changes according to the change of the external magnetic field, so it can be used to detect the intensity and direction of the magnetic field. Moreover, the TMR magnetic sensor chip has low power consumption, with its power consumption reaching the microamp level, and has higher sensitivity. While improving the sensing accuracy of the present Hall rocker 41 switch, it effectively meets the usage requirements of precision instruments that require low-power switches. The operation process and specific structure of the TMR magnetic sensor chip are well-known technologies, so only a simple description is given in this embodiment without specific elaboration.

[0036] When people shake the rocker 41, the rocker 41 drives the upper rocker arm 42 and the lower rocker arm 43 to rotate separately or drives the upper rocker arm 42 and the lower rocker arm 43 to rotate simultaneously in different directions. The first magnet 44 on the upper rocker arm 42 is driven by the upper rocker arm 42 to rotate between the base 2 and the front shell 3. The first magnet 44 and the first TMR magnetic sensor chip 11 interact with each other. When the first magnet 44 rotates, the direction and intensity of its magnetic field change, so that the first TMR magnetic sensor chip 11 senses different output voltages. The first TMR magnetic sensor chip 11 senses and transmits the sine change of the voltage according to the change of the position of the first magnet 44, and cooperates with the magnetic core induction, so as to obtain the direction and amplitude of the rocker 41 driving the upper rocker arm 42 to shake. At the same time, the second magnet 45 on the lower rocker arm 43 is driven by the lower rocker arm 43 to rotate between the base 2 and the front shell 3. The second magnet 45 and the second TMR magnetic sensor chip 12 interact with each other. When the second magnet 45 rotates, the direction and intensity of its magnetic field change, so that the second TMR magnetic sensor chip 12 senses different output voltages. The second TMR magnetic sensor chip 12 senses and transmits the sine change of the voltage according to the change of the position of the second magnet 45, and cooperates with the magnetic induction, so as to obtain the direction and amplitude of the rocker 41 driving the lower rocker arm 43 to shake, which is beneficial to improving the sensitivity and accuracy of detecting the shake of this switch, and greatly increasing the service life and performance of this switch. And this switch avoids the problems of the stuck feeling of the slider sliding and hitting the base 2 driven by the rocker 41 and the large number of transmission mechanisms. The structure of the upper rocker arm 42 and the lower rocker arm 43 being cross-perpendicular enables the rocker 41 in this switch to rotate freely by 360 degrees while still driving the upper rocker arm 42 and the lower rocker arm 43 to rotate in different directions. The transmission mechanism is less, the structure is simple, the overall structural error is small, and it can drive smoothly without a stuck feeling, and the rotation feel is better, effectively ensuring people's use experience.

[0037] Regarding the directions of the separate shakes of the upper rocker arm 42 and the lower rocker arm 43, as Figures 2 to 10 shown, the upper rocker arm 42 shakes on the X-axis, so as to drive the first magnet 44 to control the movement track of the magnetic field on the X-axis in this switch. The lower rocker arm 43 shakes on the Y-axis, so as to drive the second magnet 45 to control the movement track of the magnetic field on the Y-axis in this switch. The two cooperate with each other, so that this switch can sense the multi-angle rotation of the rocker 41 around the X-axis and the Y-axis as the axes, effectively ensuring the sensitivity and detection accuracy of this switch. The upper rocker arm 42 can also shake on the Y-axis, and the lower rocker arm 43 can also shake on the X-axis. The specific can be selected according to the actual situation, so no specific limitation is made in this embodiment.

[0038] Preferably, the circuit board 1 is an FPC flexible board, which is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the substrate, and has the characteristics of high wiring density, light weight, thin thickness, and good bending property, effectively reducing the production cost of this switch and ensuring the electrical conduction efficiency of this switch.

[0039] Preferably, as Figures 1 to 5 shown, screw holes can also be provided on the side of the base 2, and the base 2 is fixed to other machines by screws passing through the screw holes, realizing the fixation of this switch.

[0040] Regarding the specific structural setting of the upper rocker arm 42, as shown in 6, the upper rocker arm 42 includes an upper rocking bracket 421 with an overall arched shape, an upper rocker arm movable slot 422 formed in the middle of the upper rocking bracket 421, an upper rocking shaft 423 symmetrically arranged on both sides of the upper rocking bracket 421 and rotating on the base 2, and an upper hollow mounting part 424 formed at the outermost end of any group of upper rocking shafts 423 for the first magnet 44 to be embedded.

[0041] As Figures 4 to 6 shown, the rocker 41 passes through the upper rocker arm movable slot 422, and drives the entire upper rocker arm 42 to rotate through the upper rocker arm movable slot 422. The upper rocking shaft 423 rotates on the base 2. When the rocker 41 drives the upper rocker arm movable slot 422 to rock in the X-axis direction, the upper rocking bracket 421 rocks on the base 2 with the upper rocking shaft 423 as the axis, preventing the upper rocker arm 42 from shifting, and making the rocking of the upper rocker arm 42 in the X-axis direction smoother. The first magnet 44 is correspondingly embedded in the hollow position of the upper hollow mounting part 424, thereby realizing its own fixation, so that when the upper rocking shaft 423 is driven to rotate, the first magnet 44 is synchronously driven to rotate, and thus is sensed and measured by the first TMR magnetic sensor chip 11.

[0042] Regarding the specific structural setting of the lower rocker arm 43, as Figure 7 shown, the lower rocker arm 43 includes a lower rocking bracket 431 perpendicular to the upper rocking bracket 421 in the cross-horizontal direction, lower rocking linkage arc platforms 432 symmetrically formed on both sides of the upper end of the lower rocking bracket 431 and capable of being embedded in the upper rocking bracket 421, a lower rocker arm movable slot 433 formed in the middle of the lower rocking bracket 431, lower rocking shafts 434 symmetrically arranged on both sides of the lower rocking bracket 431 and rotating on the base 2, and a lower hollow mounting part 435 formed at the outermost end of any group of lower rocking shafts 434 for the second magnet 45 to be embedded.

[0043] As Figures 4 to 8As shown, by providing a lower rocking linkage arc platform 432 that can be embedded in the lower part of the upper rocking bracket 421 on the upper rocking bracket 421, during the rotation of the upper rocking bracket 421, the lower rocking bracket 431 can also be driven to rotate, so that when the rocker arm tilts and rotates, the upper rocker arm 42 and the lower rocker arm 43 can be driven to rotate simultaneously, ensuring the rocking transmission. The rocker 41 passes through the lower rocker 41 and moves, and drives the entire lower rocker arm 43 to rotate through the lower rocker 41 moving groove. By rotating the lower rocking shaft 434 on the base 2, when the rocker 41 drives the lower rocker moving groove 433 to rock in the Y-axis direction, the lower rocking bracket 431 rocks on the base 2 with the lower rocking shaft 434 as the axis, preventing the lower rocker arm 43 from shifting, and making the lower rocker arm 43 rock more smoothly in the X-axis direction. The second magnet 45 is correspondingly embedded in the hollow position of the lower hollow mounting member 435, so as to realize its own fixation, so that when the lower rocking shaft 434 is driven to rotate, the second magnet 45 is synchronously driven to rotate, and thus is sensed and measured by the second TMR magnetic sensor chip 12.

[0044] To further stabilize the various structures of this switch, such as Figures 1 to 5 As shown, this switch further includes a fixing bracket 5 installed on the circuit board 1. At least two groups of extending fixing strips 51 that are bent upward and fastened to the upper end surface of the face shell 3 are formed on the outer side of the fixing bracket 5. Preferably, there are a total of four groups of extending fixing strips 51 to fasten the fixing bracket 5 to the face shell 3, so that the structures arranged between the fixing bracket 5 and the face shell 3 are further fixed, preventing the problem of displacement of the structures between the fixing bracket 5 and the face shell 3.

[0045] Regarding the specific structural arrangement of the rocker arm assembly 4, such as Figures 1 to 5 As shown, the rocker arm assembly 4 further includes a movable disc 46 that passes through the circuit board 1 and has its lower end disposed at the upper middle part of the fixing bracket 5 and passes through the upper rocker moving groove 422 and the lower rocker moving groove 433 at one time, a reset elastic member 47 sleeved on the upper part of the movable disc 46, a dust-proof cap 48 that covers the outer end of the rocker 41 passing through the face shell 3 and has a shape matching the face shell 3, and a rotating disc 49 provided at the top end of the rocker 41; the rocker 41 is sleeved on the movable disc 46, one end of the reset elastic member 47 abuts against the upper part of the movable disc 46, and the other end abuts against the rocker 41.

[0046] Preferably, as Figure 5 shown, the reset elastic member 47 is a spring. Springs are inexpensive, have high fatigue resistance, high elasticity, are easy to process and assemble. Besides reducing the production cost of this switch, they effectively ensure the feel of pressing and the power of rebound of this switch, guaranteeing the normal operation of this switch.

[0047] As Figures 1 to 5 shown, the user's finger touches the turntable 49 and shakes to drive the rocker 41 to achieve operation and control of the direction. In this embodiment, the upper end of the turntable 49 is a circular shape protruding upward, and its lower end is fixed to the rocker 41. It can also be set in various shapes and different heights for combined use, improving the applicable range of this switch and meeting the usage requirements of different users. By providing a dust-proof cap 48 on the rocker 41 that matches the shape of the front shell 3, the dust-proof cap 48 covers the outside of the front shell 3 penetrated by the rocker 41, preventing external dust and other items from entering this switch and ensuring the normal operation of each component inside this switch. By providing a reset elastic member 47 between the rocker 41 and the movable disc 46, when the user presses the turntable 49 and drives the turntable 49 to rotate, the turntable 49 drives the rocker 41 connected thereto to press downward and rotate. The rocker 41 presses the reset elastic member 47, causing the reset elastic member 47 to deform. When the user releases the turntable 49, the rocker 41 drives the turntable 49 thereon to reset upward under the elastic restoring force of the reset elastic member 47 itself, facilitating the next use. By sleeving the rocker 41 on the movable disc 46, the lower end of the movable disc 46 is connected to the middle part of the fixed bracket 5, thereby providing a supporting force for the movement of the rocker 41. The rocker 41 rotates at multiple angles with the middle part of the fixed bracket 5 as the fulcrum, thereby achieving the purpose that this switch can be operated by rotating at multiple angles.

[0048] Regarding the specific manner in which the upper rocker arm 42 and the lower rocker arm 43 rotate on the base 2, as Figures 4 to 5 shown, a rocking activity groove 21 for the upper rocking bracket 421 and the lower rocking bracket 431 to rotate is formed in the middle part of the base 2. An upper rocking rotation groove 22 for the upper rocking shaft 423 to rotate is formed on both sides of the rocking activity groove 21. A lower rocking rotation groove 23 for the lower rocking shaft 434 to rotate is formed on the other two sides of the rocking activity groove 21. A first upper magnet rocking groove 24 for the upper hollow mounting member 424 to rotate is formed on the side edge of the base 2. A first lower magnet rocking groove 25 for the lower hollow mounting member 435 to rotate is further formed on the side edge of the base 2.

[0049] As Figures 4 to 5 shown, the upper rocking bracket 421, the lower rocking bracket 431, the rocker 41, and the movable disc 46 rotate in the rocking activity groove 21. Preferably, the length of the rocking activity groove 21 is greater than the length of the upper rocking bracket 421, and the width of the rocking activity groove 21 is greater than the length of the lower rocking bracket 431, thereby leaving sufficient space for the upper rocking bracket 421 and the lower rocking bracket 431 to rotate therein respectively.

[0050] AsFigures 4 to 5 As shown, when the rocker 41 drives the upper rocker arm 42 to rotate in the X-axis direction, the upper rocking shaft 423 in the upper rocker arm 42 rotates in the upper rocking rotation groove 22, and the upper hollow mounting member 424 in the upper rocker arm 42 drives the first magnet 44 to rotate on the first upper magnet rocking groove 24. When the rocker 41 drives the lower rocker arm 43 to rotate in the Y-axis direction, the lower rocking shaft 434 in the lower rocker arm 43 rotates in the lower rocking rotation groove 23, and the lower hollow mounting member 435 in the lower rocker arm 43 drives the second magnet 45 to rotate on the first lower magnet rocking groove 25. The position of the first upper magnet rocking groove 24 provided on the base 2 can be correspondingly set according to which group of upper rocking shafts 423 the upper hollow mounting member 424 is provided on, so no specific requirements are made in this embodiment. The position of the first lower magnet rocking groove 25 provided on the base 2 can be correspondingly set according to which group of lower rocking shafts 434 the lower hollow mounting member 435 is provided on, so no specific requirements are made in this embodiment.

[0051] Preferably, as Figure 4 shown, the length of the first upper magnet rocking groove 24 is longer than the length of the upper hollow mounting member 424, and the width of the first upper magnet rocking groove 24 is longer than the width of the upper hollow mounting member 424, so as to reserve enough space for the upper hollow mounting member 424 to drive the first magnet 44 to rotate.

[0052] Preferably, as Figure 4 shown, the length of the first lower magnet rocking groove 25 is longer than the length of the lower hollow mounting member 435, and the width of the first lower magnet rocking groove 25 is longer than the width of the lower hollow mounting member 435, so as to reserve enough space for the lower hollow mounting member 435 to drive the second magnet 45 to rotate.

[0053] Regarding the specific structural setting of the front shell 3, as Figures 1 to 5 ​As shown, a protective cover 31 which bulges upward and is overall semi-circular is formed in the middle of the front shell 3. The rocker 41 passes through the middle of the protective cover 31, and the dust cap 48 is covered on the protective cover 31. The shape of the dust cap 48 matches that of the protective cover 31, and the two cooperate with each other to effectively prevent external dust and other objects from entering the switch, ensuring the normal operation of the switch. The semi-circular structure makes the protection area of the protective cover 31 larger and more comprehensive. A second upper magnet rocking groove 32 for the rotation of the upper hollow mounting member 424 is formed on the side edge of the front shell 3, and a second lower magnet rocking groove 33 for the rotation of the lower hollow mounting member 435 is also formed on the side edge of the front shell 3. When the upper hollow mounting member 424 is driven by the rocker 41 to tilt and rotate, its raised end protrudes above the second upper magnet rocking groove 32, and its sunken end extends into the first upper magnet rocking groove 24. The first upper magnet rocking groove 24 and the second upper magnet rocking groove 32 cooperate with each other to provide sufficient space for the upper hollow mounting member 424 to drive the first magnet 44 to tilt and rotate. When the lower hollow mounting member 435 is driven by the rocker 41 to tilt and rotate, its raised end protrudes above the second lower magnet rocking groove 33, and its sunken end extends into the first lower magnet rocking groove 25. The first lower magnet rocking groove 25 and the second lower magnet rocking groove 33 cooperate with each other to provide sufficient space for the lower hollow mounting member 435 to drive the second magnet 45 to tilt and rotate.

[0054] For the specific startup mode of this switch, such as Figure 5 and Figure 10 As shown, this switch further includes a switch assembly 6 disposed between the base 2 and the circuit board 1. The switch assembly 6 includes a guide core mounting groove 61 formed on the base 2, a guide core 62 mounted on the guide core mounting groove 61 and having its upper end pressed by the lower rocker 43, and a tactile switch 63 electrically connected to the circuit board 1 and located directly below the guide core 62.

[0055] Such as Figure 5 and Figure 10As shown, when the user presses the rotary disk 49, the rotary disk 49 drives the rocker 41 connected thereto to press downward, causing the reset elastic member 47 provided on the rocker 41 to be compressed and deformed. The rocker 41 drives the upper rocker arm 42 and the lower rocker arm 43 to press and rotate synchronously, so that the lower rocking shaft 434 in the lower rocker arm 43 presses against the guide core 62 and drives the guide core 62 to press downward. The guide core 62 contacts the touch switch 63, starting the touch switch 63, conducting the circuit on the circuit board 1, and transmitting a rotation signal outward to realize operations such as flipping of the corresponding external mechanism. When the user releases the rotary disk 49, under the elastic restoring force of the reset elastic member 47, the rocker 41 drives the upper rocker arm 42 and the lower rocker arm 43 to move upward, so that the lower rocking shaft 434 in the lower rocker arm 43 leaves the guide core 62. After the guide core 62 loses the downward pressing force, it moves upward and leaves the touch switch 63, and the touch switch 63 closes, disconnecting the circuit on the circuit board 1 to achieve the purpose of saving energy and the like. For the specific manner of the upward movement of the guide core 62, springs, elastic sheets, etc. can be provided on the side of the wire, or the guide core installation groove 61 can be made of an elastic material to provide the driving force for the upward reset of the guide core 62, and it can be specifically set according to the actual situation, so no specific limitation is made in this embodiment.

[0056] Preferably, as Figure 10 shown, a contact point that can press against the touch switch 63 also extends downward on the lower surface of the guide core 62. By pressing and contacting the trigger structure on the touch switch 63 through the contact point, the start of the touch switch 63 is realized.

[0057] For the specific manner in which the rocker 41 drives the upper rocker arm 42 and the lower rocker arm 43 to move up and down, as Figure 8 shown, a driving rod 411 that penetrates between the lower rocking linkage arc platform 432 and the lower rocking bracket 431 is respectively formed on both sides of the rocker 41. The rocker 41 drives the lower rocker arm 43 to move up and down through the driving rod 411, and the lower rocker arm 43 drives the upper rocker arm 42 by embedding the lower rocking linkage arc platform 432 into the upper rocking bracket 421. Each component cooperates with each other to realize the start and close of this switch.

[0058] It should be noted here that the Hall rocker switch with smoother feel and lower power consumption disclosed in the present invention is an improvement on the specific structure, and the specific control method is not the innovation point of the present invention. For the TMR magnetic sensor chip, magnet, spring, elastic sheet, guide core, touch switch and other components involved in the present invention, they can be general standard parts or components known to those skilled in the art, and their structures, principles and control methods are all known to those skilled in the art through technical manuals or obtained through conventional experimental methods.
