Description

Technical Field

[0001] The present invention relates to the technical field of controllers, and particularly to a rocker device and an electronic device. Background Art

[0002] As a key component of human-computer interaction, the rocker device has an increasingly wide range of application scenarios. From the early arcade game controllers to today's smartphone game pads, drone remote controls, industrial equipment consoles, and then to the precise control of auxiliary devices such as wheelchairs and robotic arms, the rocker is widely adopted due to its simple structure, sensitive response, and intuitive operation.

[0003] The rocker component device of the prior art usually has a button. By pressing the rocker component, the abutting end of the rocker component abuts against the button to realize button input. However, during the use of the rocker component, the button usually needs to be triggered after the rocker component rotates to a certain angle. During the rotation of the rocker component, its abutting end will rotate as the rocker component swings, and there may be a situation where it rotates out of contact with the button, resulting in insensitive button triggering. Summary of the Invention

[0004] The main object of the present invention is to propose a rocker device and an electronic device, aiming to solve the problem that in the prior art, the rocker is out of contact with the button during rotation, resulting in insensitive button triggering.

[0005] To achieve the above object, the rocker device proposed by the present invention includes:

[0006] A housing, an installation cavity is formed inside the housing, an opening communicating with the installation cavity is formed on one side of the housing, a button is provided on the cavity wall of the installation cavity opposite to the opening, and a contact portion is formed on the side of the button facing the opening;

[0007] A rocker component, one end of the rocker component is an abutting end, the rocker component passes through the opening and extends into the installation cavity and contacts the contact portion;

[0008] A shrapnel, the shrapnel is arranged in the installation cavity and is arranged in a plane, the shrapnel surrounds the outer periphery of the rocker component and is connected to the position of the rocker component close to the abutting end; under the action of the shrapnel, the abutting end and the contact portion always remain in contact, and the rotation center of the rocker component remains unchanged when it is pushed; the shrapnel is arranged in a plane when the rocker component is not pushed, and can undergo elastic deformation when the rocker component is pushed, and can reset the rocker component through elastic restoring force.

[0009] In one embodiment, the rocker assembly includes a rocker and a push seat. The push seat is disposed in the installation cavity, and one end of the push seat forms the abutting end. The end of the push seat away from the abutting end forms a connection end. The rocker passes through the opening and extends into the installation cavity and is connected to the connection end. The elastic sheet surrounds the outer periphery of the push seat and is connected to the push seat.

[0010] In one embodiment, the cross-sectional dimension of the abutting end is tapered from the connection end towards the key, and the end face of the abutting end facing the key forms an abutting surface. The abutting surface is always in contact with the contact portion under the action of the elastic sheet.

[0011] In one embodiment, a gasket is provided around the outer periphery of the key. A buffer pad is provided between the elastic sheet and the gasket. The buffer pad has an avoidance hole corresponding to the position of the key for avoiding the key.

[0012] In one embodiment, a buffer pad is provided around the outer periphery of the key. The buffer pad is disposed between the elastic sheet and the cavity wall of the installation cavity. The buffer pad has an avoidance hole corresponding to the position of the key for avoiding the key.

[0013] In one embodiment, the elastic sheet includes an inner connection portion, a deformation portion, and an outer ring portion that are connected in sequence from the inside to the outside. The outer ring portion is connected to the housing. The deformation portion and the outer ring portion both surround the outer periphery of the push seat. The push seat is connected to the inner connection portion and the deformation portion. And the abutting end is always in contact with the contact portion under the action of the inner connection portion and the deformation portion. The deformation portion has a deformation gap. The push seat is connected to the inner connection portion.

[0014] In one embodiment, the deformation portion includes a plurality of cantilevers. Each cantilever extends from the outer ring portion towards the inner connection portion and is connected to the inner connection portion. A deformation gap is formed between any two adjacent cantilevers. The push seat is connected to all the cantilevers.

[0015] In one embodiment, each cantilever includes a first end connected to the outer ring portion and a second end connected to the inner connection portion. And each cantilever is formed by extending from the first end to the second end in a straight line and / or a curve in the same direction or different directions.

[0016] In one embodiment, the pushing seat includes a chassis, a plugging column connected to the chassis, and a plurality of plugging arms. The chassis forms the abutting end. The inner connecting portion is provided with a plugging hole, and the plugging column is plugged into the plugging hole. The chassis abuts against the side of the inner connecting portion away from the rocker. The plurality of plugging arms are arranged at intervals along the circumference of the chassis on the outer periphery of the plugging column. The number of the plugging arms is the same as the number of the deformation gaps, and each plugging arm passes through the area of the deformation gap close to the inner connecting portion and is connected to the rocker one by one.

[0017] The present invention also provides an electronic device, and the above-mentioned rocker device is applied to the electronic device.

[0018] The technical solution of the present invention is that the abutting section of the rocker assembly passes through the opening and extends into the installation cavity to contact the contact portion, and the elastic sheet is connected to the outer periphery of the rocker assembly close to the abutting end. The elastic sheet plays a role in supporting and limiting the rocker assembly, and under the action of the elastic sheet, the rotation center of the rocker assembly always remains unchanged. When the rocker assembly is not pushed, the elastic sheet is arranged in a plane, and the supporting action of the elastic sheet ensures that the abutting end of the rocker assembly always aligns with and contacts the contact portion of the key. When the rocker assembly is pushed, since the connection position of the elastic sheet and the rocker assembly is close to the abutting end, the rocker assembly forms a lever structure. No matter how large the swing amplitude of the rocker assembly is, the swing amplitude of the abutting end is relatively small, so that the abutting end can always keep in contact with the contact portion of the key during the swing process, so that the key can always be triggered when the rocker assembly is pressed, and the triggering sensitivity of the key is improved. Through the design of the connection position of the elastic sheet and the rocker assembly, the present invention enables the abutting end to always keep in contact with the contact portion of the key during the swing process, thereby improving the triggering sensitivity of the key.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all 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.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] The rocker assembly device in the prior art usually has a button, and the rocker assembly is pressed so that the abutting end of the rocker assembly abuts against the button to achieve key input. However, during use, the rocker assembly usually needs to be rotated to a certain angle to trigger the button. During the rotation of the rocker assembly, the abutting section will rotate with the swing of the rocker assembly, and there is a situation where the rocker assembly rotates to a misaligned or unable to align with the button, resulting in insensitive button triggering.

[0036] To solve the above problems, the present invention provides a rocker device 100 .

[0037] In combination, the rocker device 100 of the present embodiment includes a shell 1, a rocker assembly 2 and a spring 3. A mounting cavity 11 is formed in the shell 1. An opening 13 connected to the mounting cavity 11 is formed on one side of the shell 1. A button 12 is arranged on the cavity wall of the mounting cavity 11 opposite to the opening 13. The button 12 forms a contact portion 121 on the side facing the opening 13. One end of the rocker assembly 2 is an abutment end 225. The rocker assembly 2 extends into the mounting cavity 11 through the opening 13 and contacts the contact portion 121. The spring 3 is arranged in the mounting cavity 11 and is arranged in a plane. The spring 3 is arranged around the outer periphery of the rocker assembly 2 and is connected to the position of the rocker assembly 2 close to the abutment end 225. The rocker assembly 2 is connected to the center of the spring 3 so that the rotation center of the rocker assembly 2 remains unchanged, and the abutment end 225 always keeps in contact with the contact portion 121 under the action of the spring 3. The spring 3 can be elastically deformed when the rocker assembly 2 is pushed, and can reset the rocker assembly 2 through the elastic restoring force.

[0038] During use, the user pushes the rocker assembly 2 to achieve the direction input of the rocker device 100. The rocker assembly 2 drives the elastic sheet 3 to deform, thereby generating an elastic restoring force. During this process, since the connection between the elastic sheet 3 and the rocker assembly 2 is close to the abutting end 225, the rocker assembly 2 forms a lever structure. No matter how large the swing amplitude of the rocker assembly 2 is, the movement amplitude of the abutting end 225 is relatively small, so that the abutting end 225 can always contact the contact portion 121 of the button 12 during the swing. When the user needs to press the button 12, the rocker assembly 2 can be pressed from any angle, and the rocker assembly 2 can trigger the button 12. When the external force on the rocker assembly 2 disappears, the elastic restoring force of the rocker assembly 2 can push the rocker assembly 2 to reset.

[0039] The technical solution of the present invention is that the abutting section of the rocker assembly 2 passes through the opening 13 and extends into the installation cavity 11 to contact the contact portion 121, and the elastic sheet 3 is connected to the outer periphery of the rocker assembly 2 near the abutting end 225. The elastic sheet 3 plays a supporting and limiting role for the rocker assembly 2, and the center of the elastic sheet 3 is connected to the rocker assembly 2, so that the rotation center of the rocker assembly 2 always remains unchanged. When the rocker assembly 2 is not pushed, the supporting effect of the elastic sheet 3 ensures that the abutting end 225 of the rocker assembly 2 always aligns with and contacts the contact portion 121 of the button 12. When the rocker assembly 2 is pushed, since the connection between the elastic sheet 3 and the rocker assembly 2 is close to the abutting end 225, the rocker assembly 2 forms a lever structure. No matter how large the swing amplitude of the rocker assembly 2 is, the movement amplitude of the abutting end 225 is relatively small, so that the abutting end 225 can always contact the contact portion 121 of the button 12 during the swing, so that the button 12 can always be triggered when the rocker assembly 2 is pressed, improving the triggering sensitivity of the button 12. Through the design of the connection position between the elastic sheet 3 and the rocker assembly 2, the present invention enables the abutting end 225 to always contact the contact portion 121 of the button 12 during the swing, thereby improving the triggering sensitivity of the button 12.

[0040] In an embodiment, the rocker assembly 2 includes a rocker 21 and a pushing seat 22. The pushing seat 22 is disposed in the installation cavity 11, and one end of the pushing seat 22 forms an abutting end 225, and the end of the pushing seat 22 away from the abutting end 225 forms a connection end 227. The rocker 21 passes through the opening 13 and extends into the installation cavity 11 and is connected to the connection end 227. The elastic sheet 3 is disposed around the outer periphery of the pushing seat 22 and is connected to the pushing seat 22.

[0041] The rocker assembly 2 includes a rocker 21 and a pushing seat 22. The pushing seat 22 forms an abutting end 225. The elastic piece 3 is connected to the pushing seat 22, which facilitates the assembly of the elastic piece 3 on the pushing seat 22. Also, the elastic piece 3 can be clamped by the connection part between the rocker 21 and the pushing seat 22, improving the connection stability between the elastic piece 3 and the pushing seat 22. Specifically, the pushing seat 22 and the rocker 21 can be provided with structures such as buckles and slots for plug-in cooperation to clamp the elastic piece 3 therebetween.

[0042] In an embodiment, the cross-sectional dimension of the abutting end 225 is tapered from the connection end 227 towards the key 12, and the end face of the abutting end 225 facing the key 12 forms an abutting surface 226, and the abutting surface 226 is always in contact with the contact part 121 under the action of the elastic piece 3.

[0043] The tapered design reduces the area of the abutting surface 226 where the abutting end 225 contacts the key 12, avoiding the situation that the abutting surface 226 triggers the key 12 without being pressed during the rotation of the rocker 21 due to too large a contact area. And the small-area abutting surface 226 will only trigger the key 12 when pressed radially along the key 12. The pressing force for triggering is more precise, ensuring the same pressing force each time and a more rapid response, which helps to achieve a clear and controllable operation boundary, especially suitable for usage scenarios that require high-precision control.

[0044] Furthermore, at the position of the key 12 corresponding to the abutting surface 226, an arc-shaped protrusion 122 protrudes towards the abutting surface 226. The arc-shaped protrusion 122 forms the contact part 121. The abutting surface 226 is an arc-shaped surface protruding towards the key 12, and is always in contact with the arc-shaped protrusion 122 under the action of the elastic piece 3.

[0045] The contact part between the arc-shaped protrusion 122 and the arc-shaped abutting surface 226 is only a very small contact area. During the rotation of the rocker 21, the arc-shaped protrusion 122 is in sliding contact with the abutting surface 226, and the two always maintain a distance of fitting without extrusion, without structural interference or jamming, and always maintain stable fitting during the rotation process. It will neither accidentally press the key 12 due to local protrusions, further reducing the risk of accidental touch, nor become disengaged resulting in insensitive pressing.

[0046] In an embodiment, a buffer pad 14 is provided around the key 12. The buffer pad 14 is arranged between the elastic piece 3 and the cavity wall of the installation cavity 11. The buffer pad 14 has an avoidance hole for avoiding the key 12 at the position corresponding to the key 12. Specifically, the buffer pad 14 can be bonded to the cavity wall of the installation cavity 11 through an adhesive, such as PSA (pressure sensitive adhesive).

[0047] The buffer pad 14 is arranged between the spring piece 3 and the cavity wall of the installation cavity 11, that is, the side of the spring piece 3 away from the rocker 21, so that it can provide flexible support when the push seat 22 drives the spring piece 3 to produce a large deformation, thereby absorbing part of the reaction force when the rocker 21 is quickly reset or violently pushed, reducing the impact of the spring piece 3, especially the deformation part 32, and effectively extending the service life of the spring piece 3. At the same time, the flexible material of the buffer pad 14 can provide a certain damping when the rocker 21 is pushed to the limit, avoiding hard collision and the feeling of "sticking", thereby optimizing the operation feedback of the rocker 21, allowing the user to feel a smoother and more natural control feel. At the same time, the buffer pad 14 is arranged around the periphery of the button 12 to form a closed cavity, preventing external impurities from entering the cavity to affect the contact between the button 12 and the abutment surface 226, and preventing impurities from being stuck between the button 12 and the abutment surface 226 to cause the button 12 to be triggered by mistake, thereby ensuring the accuracy of the button 12.

[0048] In one embodiment, the spring piece 3 includes an inner connecting portion 31, a deformation portion 32 and an outer ring portion 33 which are connected in sequence from the inside to the outside, the outer ring portion 33 is connected to the shell 1, the deformation portion 32 and the outer ring portion 33 are both arranged on the outer periphery of the pushing seat 22, the pushing seat 22 is connected to the inner connecting portion 31 and the deformation portion 32, and the abutting end 225 always maintains contact with the contact portion 121 under the action of the inner connecting portion 31 and the deformation portion 32, the deformation portion 32 has a deformation gap 321, and the pushing seat 22 is connected to the inner connecting portion 31.

[0049] The outer ring portion 33 is connected to the housing 1 to form a stable fixed boundary, which prevents the entire spring piece 3 from loosening and improves the stability of the spring piece 3. The strain module is supported by the deformation portion 32 and the outer ring portion 33. A part of the strain module supported by the outer ring portion 33 is also used to provide a fixed boundary for the strain module to form a stable support. The other part of the strain module supported by the deformation portion 32 plays a role in deforming with the deformation portion 32 to generate a voltage signal. The deformation gap 321 of the deformation portion 32 can reserve a deformation space for the deformation portion 32, and the deformation resistance is smaller, so that the deformation portion 32 is more sensitive, and can be deformed accordingly for any swing of the rocker 21, thereby improving the accuracy of the rocker device 100. The push seat 22 is connected to the inner connection portion 31 and the deformation portion 32. The inner connection portion 31 and the deformation portion 32 simultaneously limit the push seat 22, ensuring that the push seat 22 is always in contact with the button 12, thereby improving the trigger sensitivity of the button 12.

[0050] In one embodiment, the deformation portion 32 includes a plurality of cantilevers 322 , each of which extends from the outer ring portion 33 to the inner connecting portion 31 and is connected to the inner connecting portion 31 , and a deformation gap 321 is enclosed between any two adjacent cantilevers 322 , and the pushing seat 22 is connected to the plurality of cantilevers 322 .

[0051] The deformation part 32 is composed of a plurality of cantilevers 322, enabling each cantilever 322 to elastically deform independently or cooperatively when the rocker 21 is stressed. When the rocker 21 swings in any direction, a corresponding cantilever 322 can deform, thereby more precisely controlling the elastic force and direction of the rocker 21 to return to its original position, and improving the stability and consistency of the return. The strain module is attached to at least some of the cantilevers 322, that is, attached to more than one cantilever 322, and covers the deformation gap 321 between some of the cantilevers 322, so that the perception of deformation by the strain module is improved from point-to-point perception to planar perception, making the perception of deformation by the strain module more sensitive.

[0052] Please refer to Figure 2 , in an embodiment, an installation platform 111 is arranged along the circumferential direction of the installation cavity 11. The outer ring part 33 is supported on the installation platform 111. One of the installation platform 111 or the outer ring part 33 is provided with a positioning post 112, and the other is provided with a positioning hole 332 that is inserted and matched with the positioning post 112.

[0053] The outer ring part 33 of the elastic sheet 3 is supported on the installation platform 111 in the installation cavity 11, and is limited and fixed by the cooperation of the positioning post 112 and the positioning hole 332, enabling the elastic sheet 3 to withstand the repeated operating forces from the pushing seat 22 and the rocker 21, preventing the elastic sheet 3 from being worn or displaced due to minute sliding during long-term use, and improving the stability and service life of the overall structure. At the same time, the installation platform 111 extends along the circumferential direction to abut against the outer ring part 33, defining the boundary of the deformation of the elastic sheet 3, which helps to ensure that the deformation only occurs in the deformation part 32 and avoids undue deformation of the outer ring part 33 during operation.

[0054] In an embodiment, each cantilever 322 includes a first end 3221 connected to the outer ring part 33 and a second end 3222 connected to the inner connection part 31, and each cantilever 322 is formed by extending from the first end 3221 to the second end 3222 in a straight line and / or a curve in the same direction or different directions.

[0055] It can be understood that the cantilever 322 can be arranged in a straight line extending in the same direction, extending directly from the inner connecting part 31 to the outer ring part 33, or in a straight line extending in different directions to form a broken line, extending from the inner connecting part 31 to the outer ring part 33 by bending, or in an arc curve, connecting from one end of the outer ring part 33 along an arc to the other end of the inner connecting part 31, or in a wave shape or a snake shape formed by a combination of straight lines and curves in different directions, and the cantilever 322 is formed by a combination of straight lines and curves. Among them, the straight cantilever 322 has a high structural rigidity and a fast response, and is suitable for application scenarios that require faster rebound and greater reset force; the arc cantilever 322 has a softer elastic curve, which is suitable for design requirements of delicate hand feel and smooth rebound process; the wavy cantilever 322 combines the advantages of straight lines and curves, and can provide good buffering performance and adjustment space while ensuring the deformation amount. Therefore, the cantilever 322 is configured to be formed by the first end 3221 extending in a straight line and / or curve along the same direction or different directions to the second end 3222, and can be optimized and designed according to the usage scenario of the cantilever 322 to obtain the best usage experience.

[0056] When the cantilever 322 is arranged in a broken line or a curve, the strain gauge extends radially inward from the first end 3221, which can more completely cover the most critical strain path during the force application process of the cantilever 322, and the effective part for collecting deformation data is longer; because when the cantilever 322 is elastically deformed, the deformation amount usually presents a nonlinear decrease or increase from the outside to the inside, the distribution of the strain gauge along its path can achieve a more accurate deformation response, which helps to improve the detection accuracy of the strain module for the angle of the rocker 21.

[0057] In one embodiment, a plurality of first connection positions 331 are arranged at intervals along the circumference of the inner side of the outer ring portion 33, and a plurality of second connection positions 311 are arranged at intervals along the circumference of the inner side of the inner connection portion 31. The number of the first connection positions 331, the cantilevers 322 and the second connection positions 311 are consistent, the first ends 3221 of the plurality of cantilevers 322 are connected to the plurality of first connection positions 331 one by one, and the second ends 3222 of the plurality of cantilevers 322 are connected to the plurality of second connection positions 311 one by one; the first connection positions 331 and the second connection positions 311 respectively connected to the first end 3221 and the second end 3222 of the same cantilever 322 are relatively distributed on both sides of the inner connection portion 31, and the connection between each strain gauge and the first ring body is arranged at the first connection position 331 of the corresponding cantilever 322.

[0058] The first and second connection positions 311 respectively connected to the first end 3221 and the second end 3222 of the same cantilever 322 are relatively distributed on both sides of the inner connection portion 31. That is, the angular difference between the first connection position 331 and the second connection position 311 is 180°. The cantilever 322 is arranged in an arc shape and is connected to the second connection position 311 after bypassing 180°, so that each cantilever 322 has a longer unfolding path, and when the rocker 21 is pushed, a larger deformation amount and a softer elastic response can be achieved, improving the comfort and precision of the operation feel. And the connection position of each strain gauge and the first ring body is set at the first connection position 331, which can more completely cover the most critical strain path during the force application process of the cantilever 322, and the effective part of collecting the deformation data is longer, thereby improving the detection accuracy of the strain module for the angle of the rocker 21.

[0059] Specifically, the number of the first connection positions 331 and the second connection positions 311 is four each, and the number of the cantilevers 322 is also four. The included angle between any two adjacent first connection positions 331 is 90°. At this time, the path of each cantilever 322 can pass through two other first connection positions 331, and the four cantilevers 322 can cover the circumference of the push seat 22, so that when the rocker 21 drives the push seat 22 to rotate in any direction, at least one cantilever 322 is designed corresponding to the swinging direction, effectively improving the reset accuracy.

[0060] In an embodiment, as Figure 5 shown, the deformation gap 321 extends from the outer ring portion 33 to the inner connection portion 31; each cantilever 322 is formed by curving and extending from the first end 3221 in the same direction to the second end 3222, and the remaining regions of each cantilever 322 except the first end 3221 protrude outward corresponding to the positions of the first connection positions 331 to form reinforcing protrusions 323.

[0061] The first connection position 331 is exactly the starting point of each cantilever 322. Since there are more elastic gaps at this position, the structural strength here is relatively low. In order to improve the durability and deformation control accuracy of this area, in this embodiment, a reinforcing protrusion 323 can be added at the first connection position 331 to increase its structural stiffness, enhance the supporting ability of the cantilever 322 during the force application and deformation process, so that the rocker 21 can still maintain good elasticity when pushed greatly, avoiding soft collapse or excessive deformation.

[0062] In one embodiment, the pushing seat 22 includes a chassis 221, a plug-in column 222 connected to the chassis 221, and a plurality of plug-in arms 223. The chassis 221 forms an abutment end 225, the inner connecting portion 31 is provided with a plug-in hole 312, the plug-in column 222 is plugged into the plug-in hole 312, and the chassis 221 abuts against the side of the inner connecting portion 31 facing away from the rocker 21; a plurality of plug-in arms 223 are arranged at circumferential intervals along the chassis 221 on the outer periphery of the plug-in column 222, the number of the plug-in arms 223 is consistent with the number of the deformation gaps 321, and they pass through the deformation gaps 321 close to the inner connecting portion 31 in a one-to-one correspondence and are connected to the rocker 21.

[0063] The plug-in column 222 and the plug-in arm 223 increase the contact points between the push seat 22 and the spring sheet 3, thereby further improving the connection stability between the push seat 22 and the spring sheet 3. The plug-in structure of the plug-in column 222 and the plug-in hole 312 allows the push seat 22 to be firmly connected to the inner connection part 31 of the spring sheet 3, 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 3. At the same time, the inner connection part 31 is located in the middle of the spring sheet 3, and the push seat 22 is connected to the inner connection part 31, so that the spring sheet 3 is always symmetrically expanded around the center of the spring sheet 3 when deforming and rebounding, which helps to improve the accuracy and consistency of the rocker 21 returning to the middle position after reset. Multiple plug-in arms 223 are spaced around the plug-in column 222, and respectively pass through multiple deformation gaps 321 of the spring sheet 3 to connect with the rocker 21, forming a multi-point support and force transmission path, which can effectively avoid the shaking or deflection problem easily caused by single-point plug-in, and improve the smoothness and center stability of the rocker 21. At the same time, multiple plug-in arms 223 connect the spring sheet 3 and the chassis 221 more firmly as a whole, so that all actions of the rocker 21 during operation can be evenly transmitted to the spring sheet 3 through the chassis 221, significantly improving the sensitivity of the response of the spring sheet 3.
