实施例一Embodiment 1

本发明实施例提供一种侧键10，如图1所示，所述侧键10可以包括：前壳101，按键102，避让孔103，无裙边侧键按片104和无裙边侧键按片104的非可视面1041。The embodiment of the present invention provides a side button 10. As shown in FIG. 1, the side button 10 may include: afront case 101, abutton 102, a escapinghole 103, a skirt-freeside button tab 104, and a skirt-free side button. Thenon-visible surface 1041 of thesheet 104 is pressed.

这里，所述按键102设置在前壳101内部主控板上。按键102是指整个侧键10内部的基本结构，固定于主控板上，用于触发预设按键功能，满足用户需求。非可视面1041是指使用过程中用户不能看到的侧键10的内面，可视面是用户使用时能够触摸到的一面。Here, thebutton 102 is disposed on the inner main control board of thefront case 101.Button 102 means wholeThe basic structure inside the side keys 10 is fixed on the main control board for triggering the preset key functions to meet user requirements. Thenon-visible surface 1041 refers to the inner surface of the side key 10 that the user cannot see during use, and the visible surface is the side that the user can touch when used.

所述避让孔103设置在前壳101上，避让孔103的个数为至少一个，可选的，避让孔的个数是与实际中终端侧键10的个数保持一致。Theavoidance hole 103 is disposed on thefront case 101, and the number of theavoidance holes 103 is at least one. Alternatively, the number of the avoidance holes is consistent with the number of the terminal side keys 10 in practice.

这里，所述无裙边侧键按片104固定在避让孔103上，且凸出所述前壳101，凸出部分用于供用户按压。无裙边侧键按片104的非可视面1041可以与按键102相接触。无裙边侧键按片104是唯一与用户相接触部件，无裙边侧键按片104的可视面1042用于供用户按压。同时，为了实现相应的预设按键功能，无裙边侧键按片104的非可视面1041需通过避让孔103与按键102相接触。Here, the skirt-free side key is fixed to theescape hole 103 by thesheet 104, and thefront case 101 is protruded for the user to press. Thenon-visible side 1041 of the skirt-freeside button tab 104 can be in contact with thebutton 102. The non-skirtside key tab 104 is the only component that is in contact with the user, and the non-skirtside button tab 104 is used for the user to press. At the same time, in order to realize the corresponding preset button function, thenon-visible surface 1041 of thewafer 104 without the skirt side key needs to be in contact with thebutton 102 through theescape hole 103.

如图2所示，所述侧键10还包括至少一个连接部件105和至少一个固定部件106。As shown in FIG. 2, the side key 10 further includes at least one connectingmember 105 and at least one fixingmember 106.

其中，至少一个连接部件105设置在无裙边侧键按片104的非可视面1041上。Therein, at least one connectingmember 105 is disposed on thenon-visible surface 1041 of the sheet-free side button 105.

例如，如图3所示，为达到更好的固定无裙边侧键按片104，连接部件105设置在无裙边侧键按片104的非可视面1041的两端，非可视面1041的每端各设一个连接部件105。For example, as shown in FIG. 3, in order to achieve a better fixed skirt-free sidekey tab 104, the connectingmember 105 is disposed at both ends of thenon-visible surface 1041 of the skirt-free sidekey tab 104, non-visible surface. A connectingmember 105 is provided at each end of the 1041.

这里，至少一个固定部件106装配在所述前壳101内部，与所述至少一个连接部件105一一连接，使至少一个连接部件105和对应的固定部件106连接时，无裙边侧键按片104固定在所述前壳101上。值得说明的是，固定部件106是与连接部件105相互配套的装置，且两者可进行连接，从而将无裙边侧键按片104固定在前壳101上。Here, at least one fixingmember 106 is fitted inside thefront case 101, and is connected one by one to the at least one connectingmember 105. When the at least one connectingmember 105 and the corresponding fixingmember 106 are connected, there is no skirt side button. 104 is fixed to thefront case 101. It is to be noted that the fixingmember 106 is a device that is mated with the connectingmember 105, and the two can be connected to fix the skirt-free side key to thefront case 101 by thesheet 104.

可选的，固定部件106是固定钢片。Optionally, the fixingmember 106 is a fixed steel sheet.

可选的，如图7所示，所述侧键10还包括：固定钢片定位结构109和固定钢片双面胶110。Optionally, as shown in FIG. 7, the side key 10 further includes: a fixed steelsheet positioning structure 109 andFixed steel sheet double-sided tape 110.

这里，固定钢片定位结构109设置在前壳101避让孔103侧，用于确定所述固定钢片106的位置。Here, the fixed steelsheet positioning structure 109 is disposed on the side of thefront case 101escape hole 103 for determining the position of the fixedsteel sheet 106.

固定钢片双面胶110用来将固定钢片106粘接在前壳101上。The fixed steel sheet double-sided tape 110 is used to bond the fixedsteel sheet 106 to thefront case 101.

这样一来，通过无裙边侧键按片上连接部件105和前壳上固定部件106的连接，使得无裙边侧键按片104固定于前壳101上，不易轻易脱落。In this way, the connection of the on-chip connecting member 105 and the front-shell fixing member 106 is performed by the non-skirt side key, so that the non-skirt side key is fixed to thefront case 101 by thesheet 104, and it is not easy to fall off easily.

当由于终端造型的原因需要将侧键10装配到前壳101上时，由于终端前壳101的工字型构造，使得内部没有足够的空间用于装配侧键10，因此，此时从终端外侧外装侧键10显得尤为重要。When the side key 10 needs to be assembled to thefront case 101 due to the terminal molding, the I-shaped configuration of the frontfront case 101 does not allow sufficient space for the side key 10 to be assembled, and therefore, from the outside of the terminal at this time The exterior side key 10 is particularly important.

例如，先将无裙边侧键按片104固定在前壳的避让孔103上，使得无裙边侧键按片104的非可视面1041在终端内部且与前壳101内部主控板上的按键102相接触，无裙边侧键按片的可视面1042凸出终端前壳101，用于用户按压；再从前壳101内部装配固定部件106，该固定部件106与无裙边侧键按片104的非可视面1041上的连接部件105进行连接，使得无裙边侧键按片104固定于前壳101上，解决了由于终端造型的原因需要将侧键10装配到前壳上101时，无法从终端内部装配侧键10的问题。For example, the skirt-free side key is first fixed to theescape hole 103 of the front case by thesheet 104, so that thenon-visible side 1041 of the non-visible side key is inside the terminal and the inner main control board of thefront case 101. Thebuttons 102 are in contact with each other, and the skirt-free side button protrudes from the visible surface 1042 of the sheet to the terminalfront case 101 for user pressing; and the fixingmember 106 is further assembled from the inside of thefront case 101, the fixingmember 106 and the skirt-free side key Theconnection member 105 on thenon-visible surface 1041 of thesheet 104 is connected such that the skirt-free side key is fixed to thefront case 101 by thesheet 104, which solves the need to assemble the side key 10 to the front case due to the terminal shape. At 101 o'clock, the problem of the side key 10 cannot be assembled from the inside of the terminal.

可选的，如图4所示，当面临的实际情况是避让孔103为完全对称结构，且无裙边侧键按片104为非对称结构时，如图5所示，侧键10还包括：防呆凹槽107和防呆凸台108。所述防呆凹槽设置在所述无裙边侧键按片104的非可视面1041，是用来确定正确的安装方向；防呆凸台108装配在前壳101避让孔103侧，与防呆凹槽107可以形成连接。Optionally, as shown in FIG. 4, when the actual situation is that theavoidance hole 103 is completely symmetrical, and the skirt side key is not asymmetric according to thesheet 104, as shown in FIG. 5, the side key 10 further includes : thefoolproof groove 107 and thefoolproof boss 108. The anti-dwelling groove is disposed on thenon-visible surface 1041 of the skirt-free sidekey sheet 104 for determining a correct mounting direction; theanti-staying boss 108 is mounted on the side of thefront casing 101 avoidinghole 103, and Thefoolproof groove 107 can form a connection.

防呆凹槽107和防呆凸台108按照所述安装方向连接，会使无裙边侧键按片104按照预设要求安装在前壳101上。Thefoolproof groove 107 and thefoolproof boss 108 are connected in the mounting direction, so that the skirt-free side key is mounted on thefront case 101 in accordance with a predetermined requirement.

这里，无裙边侧键按片104为非对称结构可以包括无裙边侧键按片104的上侧到无裙边侧键按片104的下侧是一个倾斜的斜面，或无裙边侧键按片104的左侧到无裙边侧键按片104的右侧是一个倾斜的斜面等无裙边侧键按片104的可视面1042是不对称结构的情况。通过防呆凹槽107和防呆凸台108的设置，使得无裙边侧键按片104可按照预设要求(例如：无裙边侧键按片104的上侧高于下侧，或无裙边侧键按片104的左侧高于右侧，等等)安装在前壳101上，避免出现反装的情况，从而达到结构防呆的目的。Here, the skirt-free side key according to thesheet 104 has an asymmetrical structure and may include a skirt-free sidekey sheet 104 from the upper side to the skirt-free side button. The lower side of thesheet 104 is a sloped slope, or the skirt side. Key pressThe left side of thesheet 104 to the side of the skirt-free side button 104 is a slanted bevel, etc., without the skirt side key. The visible surface 1042 of thesheet 104 is an asymmetrical structure. By the arrangement of thefoolproof groove 107 and thefoolproof boss 108, the skirt-free sidekey sheet 104 can be set according to a preset requirement (for example, the upper side of thesheet 104 without the skirt side key is higher than the lower side, or The skirt side key is mounted on thefront case 101 according to the left side of thesheet 104, and the like, so as to avoid the occurrence of the reverse mounting, thereby achieving the purpose of structural foolproofness.

例如，如图6所示，所述按键102包括：侧键柔性电路板(Flexible Printed Circuit，FPC)1021、侧键FPC补强钢片1022和薄膜按键(Dome)开关1023。For example, as shown in FIG. 6, thebutton 102 includes a Flexible Printed Circuit (FPC) 1021, a side key FPC reinforcingsteel piece 1022, and amembrane button 1023.

所述侧键FPC1021用于触发所述按键102功能，所述侧键FPC1021固定在所述主控板上。The sidekey FPC 1021 is used to trigger the function of thebutton 102, and the sidekey FPC 1021 is fixed on the main control board.
