Description

Technical Field

[0001] This utility model relates to the field of button technology, and in particular to a non-contact button with tactile feedback. Background Technology

[0002] In current button technology applications, traditional solutions have many drawbacks for scenarios requiring tactile feedback, such as game controllers and control areas of high-end electronic devices. Taking the "Hall Linear Button Switch" (Chinese Patent Publication No. CN 109119274A) as an example, it creates tactile feedback by setting contact components such as spring sheets inside the button housing. Specifically, a spring sheet is arranged inside the base housing, and a pressing block corresponding to the spring sheet's springing part is set on one side of the guide core. The tactile feedback is achieved by the contact between the pressing block and the springing part. However, this design violates the original intention of non-contact buttons. With the accumulation of use, the spring sheet inside the button is prone to aging, deformation, or mechanical fatigue, which not only affects the tactile feedback of the button but also significantly shortens the overall lifespan of the button due to continuous friction and wear on the components in contact with the spring sheet, increasing maintenance costs and inconvenience. Therefore, developing a non-contact button with tactile feedback has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0003] The present invention addresses the aforementioned shortcomings by providing a non-contact button with tactile feedback.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: a non-contact button with tactile feedback, comprising a housing, the housing comprising a base and a top cover, the top of the top cover being provided with a first magnetic element, the top end face of the top cover being provided with a through hole, a button being installed at the through hole, the button extending downward into the interior of the top cover, and a second magnetic element being fixed at the bottom of the button, the opposing surfaces of the second magnetic element and the first magnetic element having different magnetic poles.

[0005] Furthermore, the base contains a PCB board, on which a Hall sensor is mounted, and the second magnetic element cooperates with the Hall sensor to form a Hall switch.

[0006] Furthermore, the first magnetic element can be a magnet, an electromagnetic coil, or an electromagnet.

[0007] Furthermore, the second magnetic element is a magnet.

[0008] Furthermore, the Hall sensor is located directly below the second magnetic element, and a spring is provided around the Hall sensor. The lower end of the spring abuts against the PCB board, and the upper end of the spring abuts against the second magnetic element. The spring is used not only to assist the button reset, but also to protect the Hall sensor from direct impact from external forces.

[0009] Furthermore, the Hall sensor is located directly below the second magnetic element, and a convex ring is provided around the Hall sensor. The convex ring is higher than the upper surface of the Hall sensor to protect the Hall sensor from direct impact from external forces.

[0010] Furthermore, the Hall sensor is located on the side of the second magnetic element, outside the range directly below it.

[0011] Furthermore, the base and top cover of the housing are made of high-strength plastic material, which ensures both lightness and portability while providing sufficient mechanical strength.

[0012] Furthermore, the shell may be cubic, cylindrical, or other shapes, depending on the actual needs.

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. Excellent tactile feedback: By cleverly utilizing the changes in magnetic force between magnetic components, it accurately simulates the tactile feedback and impact sound of mechanical buttons, providing users with a familiar and comfortable operating feel, enhancing the fun and immersion of operation, and meeting the needs of users with demanding requirements for button operation experience.

[0015] 2. Maintain the advantages of non-contact design: Abandoning the traditional contact spring sheet structure avoids problems such as wear and aging caused by contact, fundamentally extending the button's lifespan, reducing maintenance costs, and ensuring stable operation over a long period of time.

[0016] 3. Flexible and diverse structure: By providing various layout methods for Hall sensors and magnetic elements, such as spring assistance, convex ring protection, or side layout, it can adapt to the internal space constraints and functional requirements of different devices, thus broadening the scope of application of this utility model. It can be widely used in various fields that require precise button operation, such as game controllers, industrial control equipment, and smart home terminals. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Example 1: As Figures 1 to 6 As shown, a non-contact button with tactile feedback includes a housing 1, which can be cubic, cylindrical, or other shapes, selected according to actual needs. In this embodiment, the housing is cubic. The housing 1 includes a base 101 and a top cover 102. A first magnetic element 2 is provided on the top of the top cover 102. The first magnetic element 2 can be on the outside of the top cover, the inside of the top cover, or it can be directly injection molded into the inside of the top cover. The first magnetic element 2 is a ring magnet. A through hole 103 is provided at the center of the top end face of the top cover 102. A button 3 is installed at the through hole 103. The button 3 extends downward into the inside of the top cover 102, and a second magnetic element 4 is fixed at the bottom of the button 3. The second magnetic element 4 is a magnet, and the opposite surfaces of the second magnetic element 4 and the first magnetic element 2 have different magnetic poles. A PCB board 5 is provided inside the base 101, and a Hall sensor 6 is provided on the PCB board 5. The second magnetic element 4 and the Hall sensor 6 cooperate to form a Hall switch. Furthermore, in this invention, the base 101 and top cover 102 of the housing 1 are made of high-strength plastic material, which ensures both lightness and portability while possessing sufficient mechanical strength.

[0028] The working principle of this invention is as follows: When the user presses button 3, due to the magnetic attraction of the first magnetic element 2, button 3 initially faces significant resistance during its downward movement. As button 3 continues to be pressed down, the magnetic connection changes abruptly the instant the second magnetic element 4 disengages from the first magnetic element 2, causing a significant instantaneous reduction in resistance. At this point, the user's finger can clearly feel a tactile feedback, similar to operating a traditional mechanical button, providing clear tactile feedback. When the user releases their finger, under the magnetic attraction, button 3 returns to its original position, causing the second magnetic element 4 to approach the first magnetic element 2 until the two are attracted to each other. At the moment of attraction, the magnetic elements collide with each other, producing a slight knocking sound, further enhancing the mechanical button-like feel and providing the user with a new and superior button experience.

[0029] Example 2: Figures 7 to 9 As shown, and refer to Figure 3 The illustrated product appearance diagram shows a non-contact button with tactile feedback, comprising a housing 1, which includes a base 101 and a top cover 102. A first magnetic element 2, either an electromagnetic coil or an electromagnet, is located on the top of the top cover 102. A through hole 103 is located at the center of the top surface of the top cover 102, and a button 3 is installed at the through hole 103. The button 3 extends downward into the interior of the top cover 102, and a second magnetic element 4, a magnet, is fixed at the bottom of the button 3. The opposing surfaces of the second magnetic element 4 and the first magnetic element 2 have opposite magnetic poles. A PCB board 5 is located inside the base 101, and a Hall sensor 6 is mounted on the PCB board 5. The second magnetic element 4 and the Hall sensor 6 cooperate to form a Hall switch.

[0030] The working principle of this embodiment is basically the same as that of Embodiment 1. The difference is that the first magnetic element 2 is an electromagnetic coil or electromagnet, and the first magnetic element 2 is connected to the PCB board 5. Therefore, the magnetic force can be changed by adjusting the current of the first magnetic element 2, thereby adjusting the weight of the tactile feedback.

[0031] In various embodiments of this utility model, the specific position of the Hall sensor 6 can be set according to actual needs, including but not limited to the following three situations:

[0032] The Hall sensor 6 is located directly below the second magnetic element 4. In order to protect the Hall sensor 6 from direct impact from external forces, a spring is provided around the Hall sensor 6. The lower end of the spring abuts against the PCB board 5, and the upper end of the spring abuts against the second magnetic element 4. The spring is used not only to assist the button 3 in resetting.

[0033] The Hall sensor 6 is located directly below the second magnetic element 4. In order to protect the Hall sensor 6 from direct impact from external forces, the Hall sensor 6 is located directly below the second magnetic element 4. A convex ring is provided around the Hall sensor 6, and the convex ring is slightly higher than the upper surface of the Hall sensor 6.

[0034] The Hall sensor 6 is located on the side of the second magnetic element 4, outside the range directly below it.

[0035] In addition, in various embodiments of this utility model, the Hall sensor 6 can also be replaced with other non-contact button components, such as optical sensing elements (light-emitting elements and photosensitive elements), and a light-shielding part or light-transmitting part that cooperates with the optical sensing elements (light-emitting elements and photosensitive elements) is provided on the part of the button 3 extending into the top cover 102 to form an optical switch.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
