[0038] The realization, functional characteristics and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if the embodiments of the present invention involve descriptions such as "first" and "second", the descriptions of "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] The rocker device of the prior art usually adopts a resistive potentiometer, and a metal contact pin slides on the surface of the carbon film to detect the position of the rocker assembly, thereby realizing the signal input of the rocker assembly. However, the metal pin repeatedly scratches the carbon film during use, and over time, the carbon film will gradually wear and peel off, resulting in a decrease in the positioning detection accuracy. At the same time, the peeled powder falling on the circuit board will also affect the continuity of the circuit board.

[0043] To solve the above problems, the present invention proposes a rocker device 100.

[0044] Please combine Figure 1 、 Figure 2 and Figure 8 In this embodiment, the rocker device 100 includes a housing 1, a rocker assembly 2, and a detection assembly 3. An installation cavity 11 is formed inside the housing 1, and an opening 12 communicating with the installation cavity 11 is formed on one side of the housing 1; the rocker assembly 2 passes through the opening 12 and extends into the installation cavity 11; the detection assembly 3 includes a shrapnel 31 and a strain module 32 received in the installation cavity. The shrapnel 31 is connected to the rocker assembly 2, and the strain module 32 is supported on the shrapnel 31. The detection assembly 3 further includes a control unit communicatively connected to the strain module 32; the shrapnel 31 can elastically deform when the rocker assembly 2 is pushed, and drive the strain module 32 to deform to generate a voltage signal. The strain module 32 is used to send the voltage signal to the control unit, and the control unit calculates the swing angle of the rocker assembly 2 according to the voltage signal; the shrapnel 31 can also reset the rocker assembly 2 through the elastic restoring force and restore the strain module 32.

[0045] During use, the user pushes the rocker assembly 2, and the rocker assembly 2 swings. At this time, the rocker assembly 2 drives the elastic piece 31 to deform. Since the strain module 32 is supported on the elastic piece 31, it will deform together with the deformation of the elastic piece 31. After the strain module 32 deforms, its resistance changes, making its voltage different from the voltage in the initial state. The voltage difference between the two forms a voltage signal. The strain module 32 sends the voltage signal to the controller, and the controller calculates the resistance change amount of the strain module 32 according to the specific value of the voltage change, and then calculates the deformation angle of the strain module 32, so as to obtain the swing angle of the rocker assembly 2.

[0046] The technical solution of the present invention is to set the elastic piece 31 in the installation cavity 11, and then connect the rocker assembly 2 with the elastic piece 31. When the user pushes the rocker assembly 2, the rocker assembly 2 swings. At this time, the rocker assembly 2 drives the elastic piece 31 to deform, thereby driving the strain module 32 to deform. After the strain module 32 deforms, its resistance changes, so that its internal voltage changes to generate a voltage signal. The voltage signal is sent to the controller communicatively connected thereto. The controller judges the swing angle of the rocker assembly 2 according to the specific value of the voltage signal and the material of the strain module 32, so as to realize the signal input of the rocker assembly 2. The present invention realizes the detection of the input signal of the rocker assembly 2 through the elastic piece 31 and the strain module 32 arranged on the outer periphery of the rocker assembly 2, without using a resistive potentiometer in the prior art. Therefore, the problem of carbon film wear and peeling will not occur, and almost no wear will be generated on the elastic piece 31 during the rotation of the rocker assembly 2, so that the elastic piece 31 can maintain its accuracy for a long time, improving the positioning detection accuracy of the rocker assembly 2, and there will be no peeling powder affecting the continuity of the circuit board.

[0047] Please refer to Figure 4 and Figure 5 , in an embodiment, the elastic piece 31 includes an inner connection portion 311, a deformation portion 312 and an outer ring portion 313 connected in sequence from the inside to the outside. The outer ring portion 313 is connected to the housing 1. The deformation portion 312 and the outer ring portion 313 are both arranged around the outer periphery of the rocker assembly 2, and the deformation portion 312 has a deformation gap 3121; the strain module 32 is supported on the deformation portion 312 and the outer ring portion 313.

[0048] The outer ring portion 313 is connected to the housing 1 to form a stable fixed boundary, preventing the entire elastic piece 31 from loosening and improving the stability of the elastic piece 31. The strain module 32 is supported by the deformation portion 312 and the outer ring portion 313. A part of the strain module 32 supported by the outer ring portion 313 is also used to provide a fixed boundary for the strain module 32 to form a stable support. Another part of the strain module 32 supported by the deformation portion 312 functions to generate a voltage signal by deforming together with the deformation portion 312. The deformation gap 3121 of the deformation portion 312 can allow the deformation portion 312 to reserve a deformation space, with less resistance to deformation, making the deformation portion 312 more sensitive. For any swing of the rocker assembly 2, corresponding deformation can occur, improving the accuracy of the rocker device 100.

[0049] Further, the deformation portion 312 includes a plurality of cantilevers 3122. Each cantilever 3122 extends from the outer ring portion 313 towards the inner connection portion 311 and is connected to the inner connection portion 311. A deformation gap 3121 is formed between any two adjacent cantilevers 3122; the strain module 32 is supported and attached to the deformation portion 312, and the strain module 32 extends inwards to support and attach to at least part of the cantilevers 3122 and covers part of the deformation gap 3121.

[0050] The deformation portion 312 is composed of a plurality of cantilevers 3122, enabling each cantilever 3122 to elastically deform independently or cooperatively when the rocker assembly 2 is stressed. When the rocker assembly 2 swings in any direction, a corresponding cantilever 3122 can deform, thereby more precisely controlling the elastic force and direction of the rocker assembly 2 to return to its original position, enhancing the stability and consistency of the return. The strain module 32 is attached to at least part of the cantilevers 3122, that is, attached to more than one cantilever 3122, and covers part of the deformation gap 3121 between the cantilevers 3122, enabling the strain module 32 to improve the perception of deformation from point-to-point perception to planar perception, making the strain module 32 more sensitive to deformation.

[0051] Please combine Figures 8 to 10, in an embodiment, the strain module 32 includes a transmission member 321 and a strain member 322. The transmission member 321 includes a first ring body 3211 and a plurality of transmission pieces 3212. The first ring body 3211 is supported and attached to the outer ring portion 313. The plurality of transmission pieces 3212 are evenly spaced and arranged on the inner circumference of the first ring body 3211 and extend inward, and each transmission piece 3212 is supported and attached to at least a part of the cantilever 3122 and covers a part of the deformation gap 3121. The strain member 322 includes a second ring body 3221 and a plurality of strain pieces 3222. The second ring body 3221 is supported and attached to the first ring body 3211. The number of the strain pieces 3222 is the same as that of the transmission pieces 3212 and is supported and attached to the corresponding transmission pieces 3212 one by one. The strain pieces 3222 are communicatively connected to the control unit. When the elastic piece 31 deforms, it drives the transmission pieces 3212 and the strain pieces 3222 supported thereon to deform through the cantilever 3122, so that each strain piece 3222 generates a voltage signal and sends the voltage signal to the control unit.

[0052] The transmission member 321 serves as an intermediate layer between the elastic piece 31 and the strain member 322. The first ring body 3211 is attached to the outer ring portion 313, and the transmission pieces 3212 are attached to the cantilever 3122, which can completely sense the overall and local deformations of the elastic piece 31. The second ring body 3221 is attached to the first ring body 3211, and the strain pieces 3222 are attached to the transmission pieces 3212, so that the deformations captured by the transmission member 321 can be completely and quickly transmitted to the strain pieces 3222, enabling the strain pieces 3222 to quickly sense the deformations and generate voltage signals. In the specific use process, the rocker assembly 2 drives the elastic piece 31 to deform. The deformation of the elastic piece 31 drives the transmission pieces 3212 to deform, and then the transmission pieces 3212 push the strain pieces 3222 to deform. The arrangement of the transmission pieces 3212 can effectively buffer the stress concentration of the strain pieces 3222, extend the service life of the strain pieces 3222, and reduce the hysteresis error.

[0053] In an embodiment, an adhesive layer 323 is provided between the transmission member 321 and the strain member 322. The shapes of the first ring body 3211 and the second ring body 3221 match, and the second ring body 3221 is adhered to the second ring body 3221 through the adhesive layer 323. The shapes of the transmission pieces 3212 and the corresponding strain pieces 3222 match, and each strain piece 3222 is adhered to the corresponding transmission piece 3212 through the adhesive layer 323.

[0054] The driving piece 3212 and the strain gauge 3222 are firmly bonded together by the bonding layer 323, and the first ring body 3211 and the second ring body 3221 are also firmly bonded together, making the connection between the driving member 321 and the strain member 322 closer. This can significantly reduce the stress dissipation or "hanging feeling" caused by the loose contact between materials, avoid the hysteresis or local failure of the strain gauge 3222, ensure that the deformation of each driving piece 3212 can effectively act on its corresponding strain gauge 3222, improve the response speed and accuracy of the voltage signal, and thus improve the sensing accuracy of the strain module 32 for the movement of the rocker assembly 2.

[0055] Please refer to Figure 4 and Figure 5 In an embodiment, each cantilever 3122 includes a first end 3123 connected to the outer ring portion 313 and a second end 3124 connected to the inner connecting portion 311, and each cantilever 3122 is formed by extending from the first end 3123 to the second end 3124 in a straight line and / or a curve in the same direction or different directions; the number of strain gauges 3222 is the same as the number of cantilevers 3122 and they are arranged in one-to-one correspondence. The strain gauges 3222 extend radially inward along the elastic piece 31 from the first end 3123 of the corresponding cantilever 3122 and are sequentially supported on each cantilever 3122 on the extension path.

[0056] It can be understood that the cantilever 3122 can be arranged as a straight line extending in the same direction, directly extending from the inner connecting portion 311 to the outer ring portion 313, or as a broken line formed by straight lines extending in different directions, bending and extending from the inner connecting portion 311 to the outer ring portion 313. It can also be arranged as an arc curve, connecting from one end of the outer ring portion 313 around the arc to the other end of the inner connecting portion 311. It can also be formed into a wavy or snake-like shape by combining straight lines and curves in different directions. By combining straight lines and curves, the cantilever 3122 is formed. Among them, the straight-line cantilever 3122 has high structural rigidity and rapid response, and is suitable for application scenarios that require fast rebound and large reset force; the arc-shaped cantilever 3122 has a softer elastic curve and is suitable for the design requirements of delicate touch and smooth rebound process; the wavy cantilever 3122 combines the advantages of straight lines and curves, and can provide good buffering performance and adjustment space while ensuring the deformation amount. Therefore, arranging the cantilever 3122 to be formed by extending from the first end 3123 to the second end 3124 in a straight line and / or a curve in the same direction or different directions can be optimized specifically according to the usage scenario of the cantilever 3122, so as to obtain the best user experience.

[0057] When the cantilever 3122 is arranged in a broken line or a curve, the strain gauge 3222 extends radially inward from the first end 3123, and can more completely cover the most critical strain path during the force application process of the cantilever 3122, and the effective part of the collected deformation data is longer; when the cantilever 3122 is elastically deformed, the deformation amount usually shows a non-linear decrease or increase from the outside to the inside. The distribution of the strain gauge 3222 along its path can achieve a more accurate deformation response, which helps to improve the detection accuracy of the angle of the rocker assembly 2 by the strain module 32.

[0058] In an embodiment, a plurality of first connection positions 3131 are arranged at intervals along the circumferential direction of the inner side of the outer ring portion 313, and a plurality of second connection positions 3111 are arranged at intervals along the circumferential direction of the inner side of the inner connection portion 311. The number of the first connection positions 3131, the cantilevers 3122 and the second connection positions 3111 is the same. The first ends 3123 of the plurality of cantilevers 3122 are correspondingly connected to the plurality of first connection positions 3131 one by one, and the second ends 3124 of the plurality of cantilevers 3122 are correspondingly connected to the plurality of second connection positions 3111 one by one; the first connection position 3131 and the second connection position 3111 respectively connected to the first end 3123 and the second end 3124 of the same cantilever 3122 are oppositely distributed on both sides of the inner connection portion 311, and the connection position of each strain gauge 3222 and the first ring body 3211 is arranged at the first connection position 3131 of the corresponding cantilever 3122.

[0059] The first connection and the second connection position 3111 respectively connected to the first end 3123 and the second end 3124 of the same cantilever 3122 are oppositely distributed on both sides of the inner connection portion 311, that is, the angular difference between the first connection position 3131 and the second connection position 3111 is 180°. The cantilever 3122 is arranged in an arc shape and is connected to the second connection position 3111 after bypassing 180°, so that each cantilever 3122 has a longer unfolding path, and a larger deformation amount and a softer elastic response can be achieved when the rocker assembly 2 is pushed, improving the comfort and accuracy of the operation feel. And the connection position of each strain gauge 3222 and the first ring body 3211 is arranged at the first connection position 3131, which can more completely cover the most critical strain path during the force application process of the cantilever 3122, and the effective part of the collected deformation data is longer, thereby improving the detection accuracy of the angle of the rocker assembly 2 by the strain module 32.

[0060] Specifically, the number of the first connection positions 3131 and the second connection positions 3111 is four, the number of the cantilevers 3122 is also four, and the included angle between any two adjacent first connection positions 3131 is 90°. At this time, the path of each cantilever 3122 can pass through two other first connection positions 3131, and the four cantilevers 3122 can cover the circumference of the push seat 22, so that when the rocker assembly 2 drives the push seat 22 to rotate in any direction, at least one cantilever 3122 corresponds to the swing direction design, effectively improving the reset accuracy.

[0061] In one embodiment, if Figure 5 As shown, the deformation gap 3121 extends from the outer ring portion 313 to the inner connecting portion 311; each cantilever 3122 is formed by a first end 3123 extending in a curve along the same direction to the second end 3124, and the remaining area of ​​each cantilever 3122 except the first end 3123 protrudes outward corresponding to the position of each first connecting position 3131 to form a reinforcing protrusion 3125.

[0062] The first connection position 3131 is exactly the starting point of each cantilever 3122. Since there are many elastic gaps there, the structural strength there is relatively low. In order to improve the durability and deformation control accuracy of this area, the present embodiment may add a reinforcing protrusion 3125 at the first connection position 3131 to improve its structural rigidity and enhance the supporting capacity of the cantilever 3122 during the force deformation process, so that the rocker assembly 2 can still maintain good elasticity when pushed greatly to avoid soft collapse or excessive deformation.

[0063] Please combine Figure 3 , Figure 6 and Figure 7 In one embodiment, the rocker assembly 2 includes a rocker 21 and a push seat 22, the push seat 22 is arranged in the installation cavity 11, the deformation portion 312 and the outer ring portion 313 are both arranged around the outer periphery of the rocker assembly 2, the push seat 22 includes a chassis 221 and a plug-in column 222 connected to the chassis 221, the inner connection portion 311 is provided with a plug-in hole 3112, the plug-in column 222 is plugged into the plug-in hole 3112, the side of the chassis 221 facing the inner connection portion 311 abuts against the side of the inner connection portion 311 away from the rocker 21, and the side of the chassis 221 away from the inner connection portion 311 abuts against the cavity wall of the installation cavity 11.

[0064] During specific use, the user pushes the joystick 21, and the joystick 21 drives the pushing seat 22 to swing. At this time, the joystick 21 drives the spring 31 to deform, and the spring 31 drives the strain module 32 to deform together, so that the deformation angle of the strain module 32 is calculated through the resistance change of the strain module 32, and the swing angle of the joystick 21 is obtained.

[0065] By providing the plug-in structure of the plug-in column 222 and the plug-in hole 3112, the push seat 22 can be firmly connected to the inner connection part 311 of the spring sheet 31, effectively avoiding the problem of loose connection, misalignment or falling off caused by continuous pushing or swinging during operation, and improving the connection stability between the push seat 22 and the spring sheet 31. At the same time, the inner connection part 311 is located in the middle of the spring sheet 31, and the push seat 22 is connected to the inner connection part 311 so that the spring sheet 31 is always symmetrically expanded around the center of the spring sheet 31 when deforming and rebounding, which helps to improve the accuracy and consistency of the rocker 21 returning to the middle position after reset.

[0066] In one embodiment, the pushing seat 22 further includes a plurality of insertion arms 223. The plurality of insertion arms 223 are all connected to the chassis 221 and are circumferentially spaced apart on the outer periphery of the insertion column 222. The number of the insertion arms 223 is the same as the number of the deformation gaps 3121, and each insertion arm 223 passes through the area of the deformation gap 3121 close to the inner connection part 311 and is connected to the rocker 21 in a one-to-one correspondence.

[0067] The plurality of insertion arms 223 are spaced around the insertion column 222 and are respectively connected to the rocker 21 through the plurality of deformation gaps 3121 of the elastic sheet 31, forming a multi-point support and a force transmission path, which can effectively avoid the problems of shaking or skewing easily caused by single-point insertion, and improve the smoothness and central stability of the operation of the rocker 21. At the same time, the plurality of insertion arms 223 connect the elastic sheet 31 and the chassis 221 more firmly as a whole, so that all actions during the operation of the rocker 21 can be evenly transmitted to the elastic sheet 31 through the chassis 221, significantly improving the sensitivity of the response of the elastic sheet 31.

[0068] Further, a plug rod 224 is formed by extending one side of each insertion arm 223 toward the rocker 21. One end of the rocker 21 toward the pushing seat 22 forms a plugging block 211. The plugging block 211 is circumferentially provided with a plurality of plug holes 212 that are the same in number as the plug rods 224. The plug rods 224 are in plugging cooperation with the plug holes 212 in a one-to-one correspondence, and the plugging block 211 abuts against one side of each cantilever 3122 toward the rocker 21 and close to the inner connection part 311.

[0069] Through the one-to-one plugging cooperation between the plurality of plug rods 224 on the insertion arms 223 and the plurality of plug holes 212 on the plugging block 211 of the rocker 21, a multi-point fitting connection is formed between the rocker 21 and the pushing seat 22, greatly enhancing the connection strength and connection stability between the two, so that any operation of the rocker 21 in any direction can be timely transmitted to the pushing seat 22, thereby driving the elastic sheet 31 to deform through the pushing seat 22, and greatly improving the sensitivity of the response of the elastic sheet 31.

[0070] At the same time, the plugging block 211 abuts against one side of the cantilever 3122 toward the rocker 21, so that when the rocker 21 is pressed down, the cantilever 3122 can also be driven by the plugging block 211 to be recessed downward and deformed, so that the cantilever 3122 can drive the rocker 21 to return to its original position through its elastic restoring force, realizing the pressing and resetting of the rocker 21.

[0071] Please refer to Figure 2 In one embodiment, an installation platform 111 is arranged along the circumference of the installation cavity 11. The outer ring part 313 is supported on the installation platform 111. One of the installation platform 111 or the outer ring part 313 is provided with a positioning column 112, and the other is provided with a positioning hole 3132 that is in plugging cooperation with the positioning column 112.

[0072] The outer ring portion 313 of the elastic piece 31 is supported on the mounting table 111 in the mounting cavity 11, and is limited and fixed by the cooperation of the positioning post 112 and the positioning hole 3132, so that the elastic piece 31 can withstand the repeated operating forces from the pushing seat 22 and the rocker 21, preventing the elastic piece 31 from being worn or displaced due to slight sliding during long-term use, and improving the stability and service life of the overall structure. At the same time, the mounting table 111 extends circumferentially to abut against the outer ring portion 313, defining the boundary of the deformation of the elastic piece 31, which helps to ensure that the deformation only occurs in the deformation portion 312, and prevents the outer ring portion 313 from undergoing undue deformation during operation.

[0073] In one embodiment, a buffer block 113 is further provided in the mounting cavity 11. The buffer block 113 is disposed on the side of the deformation portion 312 away from the rocker 21. The buffer block 113 surrounds the outside of the pushing seat 22 and abuts against the side of the deformation portion 312 away from the rocker 21.

[0074] The buffer block 113 is disposed on the side of the deformation portion 312 away from the rocker 21, enabling it to provide flexible support when the pushing seat 22 drives the elastic piece 31 to generate a large deformation, thereby absorbing part of the reaction force when the rocker 21 quickly resets or is vigorously pushed, reducing the impact on the elastic piece 31, especially the deformation portion 312, and effectively extending the service life of the elastic piece 31. At the same time, the flexible material of the buffer block 113 can provide a certain damping when the rocker 21 is pushed to the limit, avoiding a feeling of hard collision and "jamming", thereby optimizing the operation feedback of the rocker 21 and allowing the user to feel a smoother and more natural handling feel.
