[0039] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, the key module 200 structure involved in the embodiment of the present application includes: a housing 100 , a key module 200 and a waterproof component 300 .
[0040] Specifically, the housing 100 is provided with a accommodating cavity 110 and an opening 120, and the opening 120 is communicated with the accommodating cavity 110; the button module 200 is arranged in the accommodating cavity 110 through the opening 120, and the button module 200 has at least one button contact 210, and the button contact 210 is at least partially exposed outside the accommodating cavity 110 through the opening 120, and the button contact 210 moves along a preset direction; the waterproof component 300 includes a waterproof part 310, and the waterproof part 310 is covered outside the accommodating cavity 110, and the edge of the waterproof part 310 is sealed and connected to the edge of the opening 120, and the waterproof part 310 contacts the button contact 210 along a preset direction close to the side of the accommodating cavity 110; wherein the material of the waterproof part 310 is an elastic material.
[0041] It should be noted that the preset direction is Figure 2 The direction that x points to.
[0042] In the above-mentioned key module 200 structure, the key contact 210 of the key module 200 is used to be electrically connected to a contact (not shown) inside the electronic device. As the key contact 210 moves along a preset direction, the key contact 210 is connected or disconnected with the contact, thereby realizing the key 220 function of the above-mentioned key module 200 structure. In this process, since the waterproof member 310 is covered outside the accommodating cavity 110, and the edge of the waterproof member 310 is sealed and connected to the edge of the opening 120, the key module 200 is arranged in the accommodating cavity 110 through the opening 120. Therefore, the key module 200 can be sealed by the waterproof member 310. In the accommodating cavity 110, in order to meet the waterproof performance of the key module 200, and because the waterproof component 310 contacts the key contact 210 along a preset direction close to one side of the accommodating cavity 110, when the key contact 210 moves along the preset direction, the waterproof component 310 and the key contact 210 will be against each other. Since the material of the waterproof component 310 is elastic material, when the waterproof component 310 and the key contact 210 are against each other, the waterproof component 310 has an elastic margin to offset the thrust of the key contact 210 on the waterproof component 310, avoid the waterproof component 310 from being separated from the shell 100, and thus improve the waterproof performance of the above-mentioned key module 200.
[0043] Specifically, in the above-mentioned embodiment, the material of the waterproof component 310 is a high-elasticity TPU (Thermoplastic Urethane, i.e., thermoplastic polyurethane elastomer) material. The high-elasticity TPU material has the advantages of a wide hardness range, high mechanical strength, outstanding cold resistance and good processing performance.
[0044] Specifically, in the above-mentioned embodiment, the elastic modulus of the waterproof member 310 is E, which satisfies: 10 MPa≤E≤1000 MPa.
[0045] Specifically, in the above embodiments, E may be 10 MPa, 100 MPa, 400 MPa, 700 MPa, 1000 MPa, etc.
[0046] It should be noted that the elastic modulus E can be regarded as an indicator to measure the ease with which a material undergoes elastic deformation. The larger its value, the greater the stress that causes the material to undergo a certain elastic deformation, that is, the greater the stiffness of the material, that is, the smaller the elastic deformation under a certain stress.
[0047] It is understandable that if E is less than 10MPa, the elastic modulus of the waterproof component 310 will be too low, that is, the stiffness of the waterproof component 310 will be too small, resulting in insufficient supporting strength of the waterproof component 310. When the key contact 210 is against the waterproof component 310, plastic deformation of the waterproof component 310 will be easily caused. If E is greater than 1000MPa, the elastic modulus of the waterproof component 310 will be too high. That is, the greater the stiffness of the waterproof component 310, when the waterproof component 310 is against the key contact 210, the elastic margin of the waterproof component 310 cannot offset the thrust of the key contact 210 on the waterproof component 310, and the waterproof component 310 will easily separate from the housing 100. When the condition of 10MPa≤E≤1000MPa is satisfied, both the stiffness requirement and the elasticity requirement of the waterproof component 310 can be met.
[0048] Specifically, in the above-mentioned embodiment, the thickness of the waterproof member 310 along the preset direction is L1, which satisfies: 0.01 mm≤L1≤0.03 mm.
[0049] Specifically, in the above embodiments, L1 may be 0.01 mm, 0.02 mm, 0.03 mm, etc.
[0050] It is understandable that if L1 is less than 0.01mm, the thickness of the waterproof component 310 along the preset direction will be too small, that is, the waterproof component 310 is too thin. In this way, when the waterproof component 310 is in contact with the key contact 210, the waterproof component 310 will be easily punctured by the key contact 210, affecting the service life and waterproof performance of the waterproof component 310. If L1 is greater than 0.03mm, the thickness of the waterproof component 310 in the preset direction will be too large, that is, the waterproof component 310 is too thick. In this way, the elasticity of the waterproof component 310 will be reduced, resulting in the waterproof component 310 being unable to meet the elasticity requirement of the key contact 210 moving along the preset direction. When 0.01mm≤L1≤0.03mm, both the thickness requirement and the elasticity requirement of the waterproof component 310 can be met.
[0051] Reference Figure 3 as well as Figure 4 As shown, the waterproof component 300 further includes a fixing member 320 , the waterproof member 310 is fixedly connected to the fixing member 320 , and the fixing member 320 is sealedly connected to the edge of the opening 120 .
[0052] It can be understood that since the waterproof component 310 is fixedly connected to the fixing component 320, and the fixing component 320 is sealed to the edge of the opening 120, the waterproof component 310 can be fixed by the fixing component 320 to improve the connection stability between the waterproof component 310 and the housing 100, thereby improving the connection sealing performance between the waterproof component 310 and the housing 100, thereby improving the sealing performance of the waterproof component 310 to the button module 200.
[0053] Reference Figure 3 as well as Figure 5 As shown, the fixing member 320 is provided with an escape space 321 , and the waterproof member 310 is fixedly disposed in the escape space 321 .
[0054] It can be understood that when the waterproof component 310 is fixedly connected to the fixing component 320, the waterproof component 310 can be exposed outside the fixing component 320 through the avoidance space 321, so as to avoid the fixing component 320 interfering with the movement of the key contact 210 along the preset direction, and at the same time avoid interfering with the elastic deformation of the waterproof component 310 along the preset direction. In this way, the connection between the waterproof component 310 and the housing 100 can be further fixed by the fixing component 320, and the movement of the key contact 210 along the preset direction and the elastic deformation of the waterproof component 310 along the preset direction can be satisfied through the avoidance space 321 of the fixing component 320.
[0055] Continue to refer to Figure 3 as well as Figure 5 As shown, the fixing member has a fixing portion 322 , the fixing portion 322 is surrounded by the avoidance space 321 , and the fixing portion 322 is sealed and connected to the edge of the opening 120 .
[0056] It can be understood that when the waterproof component 310 is further fixed by the fixing component 320, the waterproof component 310 can be fixed to the outer shell 100 by the fixing portion 322 of the fixing component 320, and the fixing portion 322 is sealed and connected to the edge of the opening 120. In this way, the sealing of the connection between the fixing portion 322 and the outer shell 100 can be ensured, thereby ensuring the sealing of the connection between the waterproof component 310 and the outer shell 100, so that the button module 200 can be sealed into the accommodating cavity 110 through the waterproof component 310.
[0057] Reference Figure 5 As shown, the width of the fixing portion 322 enclosed in the avoidance space 321 is L2, which satisfies: 3.6 mm≤L2≤4.3 mm.
[0058] Specifically, in the above embodiments, L2 can be 3.6 mm, 3.8 mm, 4.0 mm, 4.3 mm, etc.
[0059] It is understandable that if L2 is less than 3.6 mm, the width of the fixing portion 322 enclosed in the avoidance space 321 will be too small, which will make the contact area between the fixing member 320 and the housing 100 too small, thereby reducing the fixing effect of the fixing member 320 on the waterproof member 310. At the same time, when the total area of the fixing member 320 remains unchanged, the area of the avoidance space 321 will be too large, so that the area of the waterproof member 310 will be too large, thereby affecting the elastic performance of the waterproof member 310 and causing the supporting strength of the waterproof member 310 to be insufficient. When the key contact 210 is against the waterproof member 310, it is easy to cause the waterproof member 310 to be Plastic deformation, if L2>4.3mm, the width of the avoidance space 321 surrounded by the fixing part 322 will be too large. When the total area of the fixing part 320 remains unchanged, it will easily lead to the area of the avoidance space 321 being too small, which will make the area of the waterproof part 310 too large, thereby affecting the elastic performance of the waterproof part 310, and interfering with the elastic deformation of the waterproof part 310, making it impossible for the waterproof part 310 to meet the elasticity requirements. When L2 satisfies: 3.6mm≤L2≤4.3mm, it can not only meet the fixing requirements of the fixing part 322 for the waterproof part 310, but also meet the elasticity requirements of the waterproof part 310.
[0060] Specifically, in the above-mentioned embodiment, the side where the fixing portion 322 is sealed to the edge of the opening 120 has a first sealing layer (not shown), and the fixing portion 322 is sealed to the edge of the opening 120 through the first sealing layer. The width of the first sealing layer is L3, satisfying: 0.8mm≤L3≤1.2mm.
[0061] Specifically, in the above embodiments, L3 may be 0.8 mm, 1.0 mm, 1.2 mm, etc.
[0062] It is understandable that if L3 is less than 0.8mm, the width of the first sealing layer will be too small, and the area of the sealed connection between the fixing member 320 and the housing 100 will be too small, thereby reducing the sealing performance of the fixing member 320. At the same time, when the key contact 210 is against the waterproof member 310 and applies a thrust away from the housing 100 to the waterproof member 310, the edge of the fixing portion 322 and the opening 120 will easily fall off. If L3 is greater than 1.2mm, the area of the sealed connection between the fixing member 320 and the housing 100 will be too large. In this way, the resistance to the elastic deformation of the waterproof member 310 along a preset direction will be increased, thereby interfering with the elastic deformation of the waterproof member 310, making it impossible for the waterproof member 310 to meet the elasticity requirements. When L3 satisfies: 0.8mm≤L2≤1.2mm, it can not only meet the sealing performance between the fixing member 320 and the housing 100, but also meet the elasticity requirements of the waterproof member 310.
[0063] Specifically, in the above-mentioned embodiment, the first sealing layer is a first sealing adhesive layer.
[0064] Specifically, in the above-mentioned embodiment, the side of the fixing portion 322 away from the outer shell 100 along the preset direction also has a second sealing layer (not shown), and the second sealing layer is a second sealant layer. The viscosity of the first sealant layer is greater than the viscosity of the second sealant layer. The side of the fixing portion 322 away from the outer shell 100 along the preset direction is connected to a fixing jig (not shown) through the second sealing layer, so as to position and fix the connection of the fixing member 320 on the outer shell 100 through the fixing jig. Since the viscosity of the first sealant layer is greater than the viscosity of the second sealant layer, when the fixing member 320 is fixedly connected to the outer shell 100, it is convenient to separate the fixing jig from the fixing member 320.
[0065] Reference Figure 4 As shown, the housing 100 is further provided with at least one avoidance opening 130, each avoidance opening 130 is communicated with the accommodating cavity 110, and the avoidance opening 130 and the opening 120 are respectively located at two ends of the accommodating cavity 110 along a preset direction, and the button module 200 includes at least one button 220, one end of each button 220 along the preset direction is connected to at least one button contact 210, and the other end of each button 220 along the preset direction is at least partially exposed outside the accommodating cavity 110 through the avoidance opening 130.
[0066] It can be understood that the button 220 of the button module 200 is used for the user to press. When in use, the user presses the button 220 to make the button 220 drive the button contact 210 to move along the preset direction, so that the button contact 210 can contact the contact inside the electronic device, thereby making the button contact 210 electrically connected to the contact, so as to realize the button 220 function of the button module 200. In this process, since the other end of each button 220 along the preset direction is at least partially exposed outside the accommodating cavity 110 through the avoidance opening 130, the button 220 can be at least partially exposed outside the accommodating cavity 110 through the avoidance opening 130, so that the user can operate the button 220. At the same time, since one end of each button 220 along the preset direction is connected to at least one button contact 210, when the user presses the button 220, the button 220 can drive the button contact 210 to move along the preset direction.
[0067] The electronic device involved in the embodiment of the present application includes: the above-mentioned key module 200 structure.
[0068] In the above electronic device, since the above key module 200 structure can improve the waterproof performance, the service life of the above key module 200 structure can be extended, thereby extending the service life of the above electronic device.
