Technical Field
[0001] The utility model relates to the technical field of keypad waterproof structures, in particular to a keypad waterproof structure for a triple-proof mobile phone. Background Art
[0002] The characteristics of a rugged phone are very simple, that is, a phone with slight dustproof, shockproof and waterproof functions, mainly for young users who love outdoor sports or professional users with special needs. With its professional waterproof, dustproof and excellent anti-fall and anti-rollover performance, a rugged phone can be used in extremely harsh weather conditions and special occasions.
[0003] In the prior art, there are generally two ways to waterproof the side buttons of a three-proof mobile phone. One is that the three-proof shell is made of thermoplastic polyurethane rubber (TPU) as a whole, wherein the side button is integrated with the shell. Since TPU waterproofing can meet the requirements, it can also indirectly make the side button waterproof. However, in actual situations, due to the poor softness of TPU, the feel of pressing the side button is also poor. The other is that the side button is separately arranged from the shell, wherein the side button relies on gluing to achieve the waterproof function. In fact, gluing increases the process and is easy to The glue is not evenly applied. In addition, since the glue is fluid, the formed glue film will be uneven. When the glue film is uneven, the side button cannot be pressed to the correct position when it is pressed. In addition, no matter which method is used, the side button needs to be pressed to the trigger button inside the shell. When the trigger button is triggered, the control motherboard in the shell will output the corresponding control signal, thereby enabling the mobile phone to perform the corresponding function. Therefore, the market urgently needs a waterproof structure that is assembled from the outside to the inside and simplifies the buttons. The structure is simple to assemble, reliable in waterproofing, and the buttons do not affect the feel of the mobile phone buttons. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a waterproof structure for a keypad of a triple-proof mobile phone.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof structure for triple-proof mobile phone buttons, including a mobile phone case, the inner wall of the mobile phone case is provided with a shell fine rib position, a keycap is arranged inside the mobile phone case, a protruding rib is arranged on the surface of the keycap, a keycap inner ring is fixed at the bottom of the keycap, a supporting cylinder is fixed inside the keycap, a contact pin is fixed at the bottom of the supporting cylinder, a plastic bracket is fixed inside the keycap, a grab hook is fixed at the bottom of the plastic bracket, the plastic bracket is fixedly connected to the mobile phone case through the grab hook, and a side key FPC is fixed inside the mobile phone case. In the prior art, two methods are generally used for the waterproof structure of the triple-proof mobile phone side button. One is that the triple-proof shell is made of thermoplastic polyurethane rubber (i.e. TPU) as a whole, wherein the side button is integrally arranged with the shell. Since the waterproofness of TPU can meet the requirements, it can also indirectly make the side button waterproof. However, in actual situations, due to the poor softness of TPU, the feel of pressing the side button is also poor. The other method adopts a method in which the side button is separately arranged from the shell, wherein the side button is glued to In order to realize the waterproof function, in fact, gluing increases the process and is prone to uneven gluing. In addition, due to the fluidity of glue, the glue film after molding will be uneven. When the glue film is uneven, the side button cannot be pressed to the correct position when it is pressed. In addition, no matter which method is used, the side button needs to be pressed to the trigger button inside the shell. When the trigger button is triggered, the control motherboard in the shell will output the corresponding control signal, thereby making the mobile phone execute the corresponding function. Therefore, the market urgently needs a waterproof method that assembles from the outside to the inside and simplifies the button. The utility model has a waterproof structure with simple assembly and reliable waterproofness. The buttons do not affect the feel of the mobile phone buttons. To solve this problem, the utility model assembles the button keycap and the plastic bracket. When the user installs the keycap, the inner ring of the keycap is wrapped around the plastic bracket, and the plastic bracket is fixed in the mobile phone case with the help of the hook at the bottom of the plastic bracket. The user presses the keycap and presses the supporting cylinder downward, so that the supporting cylinder foot contacts the pin and contacts the side key FPC to realize the button function. At the same time, the keycap is tightly connected to the mobile phone case to achieve the waterproof function and good button touch.
[0006] Preferably, the grab hook is fixed outward in the reverse direction, and is fixed at a positive and a negative bevel angle, so as to achieve the effect of both rapid fixation and material saving.
[0007] Preferably, the inner diameter of the cross-section of the key cap inner ring is smaller than the inner diameter of the cross-section of the plastic bracket. By making the inner diameter of the key cap ring smaller than the plastic bracket, the effect of preventing the plastic bracket from falling off is achieved.
[0008] Preferably, the keycap is made of waterproof silicone, and the good hydrophobic property of the waterproof silicone is used to further improve the waterproof performance of the keycap.
[0009] Preferably, the keycap is snap-fitted with the thin ribs of the shell via the protruding ribs, and the snap-fitting of the ribs can further improve the fixing performance and waterproof performance of the keycap.
[0010] Preferably, the inner ring of the keycap is tightly connected to the mobile phone case through a hook to prevent water from flowing in through the gap between them.
[0011] Beneficial Effects
[0012] 1. In the prior art, two methods are generally used for the waterproof structure of the side buttons of the three-proof mobile phone. One is that the three-proof shell is made of thermoplastic polyurethane rubber (i.e. TPU) as a whole, wherein the side button is integrated with the shell. Since TPU waterproof can meet the requirements, it can also indirectly make the side button waterproof. However, in actual situations, due to the poor softness of TPU, the feel of pressing the side button is also poor. The other method is to separately set the side button from the shell, wherein the side button relies on gluing to achieve the waterproof function. In fact, gluing increases the number of steps and is prone to uneven gluing. In addition, since the glue is fluid, it will cause the glue film after molding to be uneven. When the glue film is uneven, it will cause the side button to be pressed. It cannot be pressed to the correct position. In addition, no matter which method is used to press , both require the side button to be pressed to the trigger button inside the shell. When the trigger button is triggered, the control motherboard in the shell will output the corresponding control signal, thereby causing the mobile phone to perform the corresponding function. Therefore, the market urgently needs a waterproof structure that simplifies the buttons by assembling from the outside to the inside. The waterproof structure is simple to assemble, reliable in waterproofing, and the buttons do not affect the feel of the mobile phone buttons. To address such problems, the utility model assembles the key caps with the plastic brackets. When the user installs the key caps, the inner ring of the key caps is wrapped around the plastic bracket, and the plastic bracket is fixed in the mobile phone case with the help of the hooks at the bottom of the plastic bracket. The user presses the key caps and presses the supporting cylinder downward, so that the supporting cylinder foot contacts the pins and contacts the side key FPC to realize the button function. At the same time, the key caps are tightly connected to the mobile phone case to achieve the waterproof function and good button touch. BRIEF DESCRIPTION OF THE DRAWINGS
