Description

Technical Field

[0001] This invention relates to the field of electronic products, and in particular to a design method for an access control host, an access control sub-host, silicone buttons, and silicone buttons. Background Technology

[0002] Silicone buttons are used to turn electronic products on and off, such as access control main units and extension units. Currently, many electronic products design their silicone buttons according to their own structure, resulting in good tactile feedback. However, the product parameters (such as stroke, rebound force, and load capacity) selected during the design of existing silicone buttons are determined entirely by the experience of design engineers and through repeated adjustments and tests. Therefore, there are issues with the development cycle of silicone buttons and their strong dependence on the design experience of design engineers. Summary of the Invention

[0003] The purpose of this invention is to provide a design method for an access control host, an access control sub-host, a silicone button, and a silicone button, so as to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the solution of the present invention is:

[0005] A method for designing silicone buttons for electronic products, comprising the following steps:

[0006] Determine the standard design thickness of the load-bearing inclined wall, the design load value, and the design contact force value of the silicone button: Based on the type of electronic product and the load variation rate ρ of the selected silicone material with thickness, determine the standard design thickness T, the design load value PF, and the design contact force value CF of the load-bearing inclined wall of the silicone button.

[0007] Determine the travel design value of the silicone button: The travel design value S of the silicone button is calculated based on the load design value PF, the contact force design value CF, the pressing force Fx and the rebound force Fy of the push switch selected for the electronic product, the installation space parameters for installing the silicone button in the electronic product, and the corresponding travel correction value S1 and travel error value S2.

[0008] Determine the load-bearing inclined wall angle of the silicone button: Calculate the load-bearing inclined wall angle θ of the silicone button based on the installation space parameters for installing silicone buttons in electronic products, as well as the corresponding angle correction value θ1 and angle error value θ2.

[0009] The installation space parameters for installing silicone buttons on electronic products include the active height a and the pressing radius b; based on the installation space parameters for installing silicone buttons on electronic products, and the corresponding angle correction value θ1 and angle error value θ2, the specific load-bearing inclined wall angle θ of the silicone button is calculated as follows:

[0010] Substitute the activity height a, pressing radius b, angle correction value θ1, and angle error value θ2 into the formula: θ=arctan(a / b)-θ1±θ2.

[0011] The installation space parameters for installing silicone buttons in electronic products include the active height a and the pressing radius b. The specific travel design value S of the silicone button is calculated based on the load design value PF, the contact force design value CF, the pressing force Fx and rebound force Fy of the selected push switch in the electronic product, the installation space parameters for installing silicone buttons in the electronic product, and the corresponding travel correction value S1 and travel error value S2.

[0013] The standard design thickness T, design load value PF, and design contact force value CF of the silicone button's inclined wall are determined based on the type of electronic product and the load variation rate ρ of the selected silicone material; specifically:

[0014] First, select the appropriate initial actuation force range for the silicone button from the silicone button design experience table according to the type of electronic product. The maximum value in this actuation force range is the initial load design value PF0 of the silicone button, and the minimum value is the initial contact force design value CF0 of the silicone button. Then, calculate the theoretical thickness T0 of the load-bearing inclined wall of the silicone button based on the initial load design value PF0 and the load variation rate ρ of the selected silicone material with thickness. Next, select a suitable standard design thickness T of the load-bearing inclined wall based on the theoretical thickness T0 of the load-bearing inclined wall. Finally, obtain the load design value PF and the contact force design value CF from the load curve corresponding to the design thickness T.

[0015] Based on the preliminary load design value PF0 and the load variation rate ρ of the selected silicone material with thickness, the theoretical thickness T0 of the load-bearing inclined wall of the silicone button is calculated as follows:

[0016] Substituting the initial design load value PF0 and the load variation rate ρ with thickness into the formula: T0=PF0 / ρ.

[0017] Based on the theoretical thickness T0 of the load-bearing inclined wall, select a suitable standard design thickness T for the load-bearing inclined wall to meet the following requirements:

[0028] Silicone button B, pressing part B1, pressing contact B11, fixing part B2, load-bearing inclined wall B3, overlapping edge B4. Detailed Implementation

[0029] This invention discloses a method for designing silicone buttons for electronic products. The silicone button B includes a pressing part B1, a fixing part B2, and a load-bearing inclined wall B3 connecting the pressing part B1 and the fixing part B2. A pressing contact B11 is provided on the bottom side of the pressing part B1. The height difference between the bottom side of the pressing contact B11 and the bottom surface of the fixing part B2 is the stroke of the silicone button B. The angle between the load-bearing inclined wall B3 and the fixing part B2 is the load-bearing inclined wall angle θ. The silicone button design method includes the following steps:

[0030] Determine the standard design thickness of the load-bearing inclined wall, the design load value, and the design contact force value of the silicone button: Based on the type of electronic product and the load variation rate ρ of the selected silicone material with thickness, determine the standard design thickness T, the design load value PF, and the design contact force value CF of the load-bearing inclined wall of the silicone button B.

[0031] Determine the travel design value of the silicone button: The travel design value S of the silicone button B is calculated based on the load design value PF, the contact force design value CF, the pressing force Fx and the rebound force Fy of the push switch A3 selected by electronic product A, the installation space parameters for installing silicone button B in electronic product A, and the corresponding travel correction value S1 and travel error value S2.

[0032] Determine the load-bearing inclined wall angle of the silicone button: Calculate the load-bearing inclined wall angle θ of the silicone button B based on the installation space parameters of the electronic product A for installing the silicone button B, as well as the corresponding angle correction value θ1 and angle error value θ2.

[0033] Specifically, in this invention, the installation space parameters for mounting the silicone button B on the electronic product A include the active height a and the pressing radius b; in conjunction with Figure 2 As shown, the active height a refers to the distance from button A1 of electronic product A to circuit board A2 of electronic product A, and the pressing radius b refers to the radius of button A1 on electronic product A. Button A1 is used to fit onto silicone button B, and people press silicone button B by touching button A1. The active height a and pressing radius b can be determined during the structural design of electronic product A.

[0034] In this invention, the load-bearing inclined wall angle θ of the silicone button B is calculated based on the installation space parameters of the electronic product A for installing the silicone button B, as well as the corresponding angle correction value θ1 and angle error value θ2. Specifically, the active height a, pressing radius b, angle correction value θ1 and angle error value θ2 are substituted into the formula: θ=arctan(a / b)-θ1±θ2.

[0035] In this invention, the travel design value S of the silicone button B is calculated based on the load design value PF, the contact force design value CF, the pressing force Fx and rebound force Fy of the push switch selected for the electronic product, the installation space parameters for the silicone button B installed in electronic product A, and the corresponding travel correction value S1 and travel error value S2. Specifically, the load design value PF, the contact force design value CF, the pressing force Fx, the rebound force Fy, the active height a, the travel correction value S1, and the travel error value S2 are substituted into the formula: S=a-[(PF+Fx) / a]·(CF+Fy)-S1±S2. Wherein, the active height 'a' represents the height of silicone button B in its initial position, and the value of active height 'a' also represents the maximum height difference of silicone button B's movement; (PF+Fx) represents the maximum force acting on silicone button B. According to Hooke's Law, [(PF+Fx) / a] represents the stiffness coefficient of silicone button B; (CF+Fy) represents the force acting on silicone button B when it is pressed to its lowest position. According to Hooke's Law, [(PF+Fx) / a]·(CF+Fy) represents the height of silicone button B when it is pressed to its lowest position; the theoretical travel design value S0 of silicone button B is obtained by subtracting the height of silicone button B when it is in its initial position from the height of silicone button B when it is pressed to its lowest position. S0-S1±S2 is the travel design value S of silicone button B.

[0036] In this invention, the standard design thickness T, design load value PF, and design contact force value CF of the load-bearing inclined wall of the silicone button B are determined based on the type of electronic product and the load variation rate ρ of the selected silicone material. Specifically, firstly, based on the type of electronic product A, a corresponding initial pressing force range for the silicone button B is selected from the silicone button design experience table. The maximum value in this pressing force range is the initial load design value PF0 of the silicone button B, and the minimum value is the initial contact force design value CF0 of the silicone button B. Then, based on the initial load design value PF0 and the load variation rate ρ of the selected silicone material, the theoretical thickness T0 of the load-bearing inclined wall of the silicone button B is calculated. Next, a suitable standard design thickness T of the load-bearing inclined wall is selected based on the theoretical thickness T0 of the load-bearing inclined wall. Finally, the design load value PF and design contact force value CF are obtained from the load curve corresponding to the design thickness T.

[0037] In this invention, the theoretical thickness T0 of the load-bearing inclined wall of the silicone button B is calculated based on the preliminary load design value PF0 and the load-bearing variation rate ρ of the selected silicone material. Specifically, the preliminary load design value PF0 and the load-bearing variation rate ρ are substituted into the formula: T0 = PF0 / ρ. Here, the load-bearing variation rate ρ specifically represents the ratio of the increase in load of the load-bearing inclined wall to the increase in thickness of the load-bearing inclined wall. The appropriate standard design thickness T of the load-bearing inclined wall is selected based on the theoretical thickness T0 to meet the following requirements: the load design value PF and the contact force design value CF obtained from the load curve corresponding to the standard design thickness T are closest to the preliminary load design value PF0 and the preliminary contact force design value CF0. The purpose of selecting an appropriate standard design thickness T for the load-bearing inclined wall in this invention is to reduce development and production costs, because existing standard design thicknesses for load-bearing inclined walls are already designed and tested data that can be used directly. Furthermore, the silicone button design experience table and the corresponding standard design thicknesses for load-bearing inclined walls are well-known technical development materials for those skilled in the art and do not require separate acquisition.

[0038] To further explain the silicone button design method of the present invention, the process of designing a silicone button for an electronic product using this design method is described in detail below.

[0039] Specifically, electronic product A is an access control host or access control extension (access control host or access control extension belongs to intercom). The installation space parameters for silicone button installation of electronic product A include an active height a of 3.2mm, a pressing radius b of 12.3mm, a rebound force Fx of the selected push switch A3 of electronic product A of 130g, and a rebound force Fy of 50g. The hardness of silicone button B is selected as 60A, and the load variation rate ρ of silicone with a hardness of 60A with thickness is 400g / mm. The angle correction value θ1 and angle error value θ2 are designed to be 1°, the stroke correction value S1 is designed to be 0.4mm, and the stroke error value S2 is designed to be 0.3mm.

[0040] Based on the fact that electronic product A is a telephone or walkie-talkie, the initial pressing force range of silicone button B for electronic product A is selected from the silicone button design experience table (see Table 1 below) as 80g-150g. Thus, the initial load design value of silicone button B is PF0 = 150g, and the initial contact force design value of silicone button B is CF0 = 80g.

[0041] Substituting the active height a, pressing radius b, angle correction value θ1, and angle error value θ2 of electronic product A into the formula: θ=arctan(a / b)-θ1±θ2=arctan(3.2 / 12.3)-1°±1°, the load-bearing inclined wall design angle θ of the silicone button B is calculated to be 14°±1°.

[0042] Substituting the preliminary load design value PF0 and the load variation rate ρ with thickness into the formula: T0=PF0 / ρ=(150 / 400)mm=0.375mm; as shown in Table 2 below, the load design value PF and contact force design value CF obtained from the load curve corresponding to the standard design thickness T=0.3mm of the load-bearing inclined wall are closest to the preliminary load design value PF0 and the preliminary contact force design value CF0. The load design value PF=150g and the contact force design value CF=90g of this load curve.

[0043] Substituting the load design value PF, contact force design value CF, pressing force Fx, rebound force Fy, active height a, stroke correction value S1, and stroke error value S2 into the formula: S=a-[(PF+Fx) / a]·(CF+Fy)-S1±S2={3.2-[(150+130) / 3.2]·(90+50)-0.4±0.3}mm=(1.2±0.3)mm; after matching with the height of the push switch A3 of the electronic product, the stroke design value S was adjusted, and the stroke design value S of the silicone button B was finally selected as 0.95mm.

[0048] Cooperate Figure 1 As shown, in this invention, the pressing contact B11 of the silicone button B is tapered. This pressing contact B11 is used to press the push switch A3 of the electronic product A. The tapered pressing contact B11 can form point contact with the push switch A3, thereby improving the pressing feel of the silicone button B. A rim B4 is formed around the outer periphery of the silicone button B. This rim B4 is used to overlap with the housing A4 of the electronic product A to prevent the silicone button B from shifting. Furthermore, the outer periphery of the silicone button B can be tightly clamped between the housing A4 and the circuit board A2 of the electronic product A, thereby sealing the button hole A41 of the housing A4 and providing a waterproof function.
