图2是图1中A部分的放大图。Fig. 2 is an enlarged view of part A in Fig. 1 .

具体实施方式 Detailed ways

请参考图1，其揭示了一电子装置10。该电子装置10包括一壳体20及一可更换地安装于壳体20上的前面板30。通过更换前面板30，可以方便的改变电子装置10的外形，从而满足消费者个性化的需求。壳体20和前面板30通过多个斜面卡扣40连接。Please refer to FIG. 1 , which discloses an electronic device 10 . The electronic device 10 includes a casing 20 and a front panel 30 replaceably mounted on the casing 20 . By replacing the front panel 30, the shape of the electronic device 10 can be easily changed, so as to meet the individual needs of consumers. The housing 20 and the front panel 30 are connected through a plurality of inclined buckles 40 .

请参考图2，壳体20由前盖22和后盖21组成，前面板30安装于前盖22上。Please refer to FIG. 2 , the casing 20 is composed of a front cover 22 and a rear cover 21 , and the front panel 30 is installed on the front cover 22 .

在前面板30上形成有斜面卡扣40的卡入部41，卡入部41包括一从前面板30延伸的弹性臂42和位于弹性臂42远离前面板30一端的卡钩43，卡钩43包括一靠近弹性臂42的斜面44和一远离弹性臂42的第二斜面45，且斜面44和弹性臂42之间的夹角大于90°。On the front panel 30 is formed a snap-in portion 41 of an inclined buckle 40. The snap-in portion 41 includes an elastic arm 42 extending from the front panel 30 and a hook 43 located at the end of the elastic arm 42 away from the front panel 30. The hook 43 includes a The inclined surface 44 of the elastic arm 42 and a second inclined surface 45 away from the elastic arm 42 , and the angle between the inclined surface 44 and the elastic arm 42 is greater than 90°.

在前盖22上形成有斜面卡扣40的扣止部46，扣止部46包括一用于容纳卡入部41的通孔47和一用于和卡钩43配合、防止卡入部41退出通孔47的止动件48，止动件48上形成有用于和卡钩43上斜面44接触的斜面49。在本实施方式中，止动件48形成于通孔47外，在其他实施方式中，止动件48也可形成于通孔47内的壁上。On the front cover 22 is formed a buckle portion 46 of the bevel buckle 40, the buckle portion 46 includes a through hole 47 for accommodating the snap-in portion 41 and a hole 47 for cooperating with the hook 43 to prevent the snap-in portion 41 from exiting the through hole 47 of the stopper 48 , the stopper 48 is formed with an inclined surface 49 for contacting the inclined surface 44 on the hook 43 . In this embodiment, the stopper 48 is formed outside the through hole 47 , and in other embodiments, the stopper 48 may also be formed on the wall inside the through hole 47 .

当需要将前面板30安装到壳体20上时，首先，将前面板30和壳体20彼此接触，每个卡入部41和扣止部46彼此对应，卡钩43的第二斜面45和通孔47的壁接触。然后，用力驱使前面板30和壳体20彼此贴紧，卡钩43向通孔47内运动，通孔47的壁顶触卡钩43，使得和卡钩43相连的弹性臂42变形，卡钩43因此可通过通孔47。当卡钩43通过通孔47后，弹性臂42恢复原状，卡钩43的斜面44和扣止部46的斜面49配合，限制卡钩43从通孔47中退出。从而，壳体20和前面板30即被连接在一起。When it is necessary to install the front panel 30 on the housing 20, firstly, the front panel 30 and the housing 20 are in contact with each other, each snap-in part 41 and the buckle part 46 correspond to each other, the second slope 45 of the hook 43 and the through The walls of the holes 47 are in contact. Then, forcefully drive the front panel 30 and the housing 20 to be close to each other, the hook 43 moves in the through hole 47, and the wall of the through hole 47 touches the hook 43, so that the elastic arm 42 connected to the hook 43 is deformed, and the hook 43 can thus pass through hole 47 . When the hook 43 passes through the through hole 47 , the elastic arm 42 returns to its original shape, and the inclined surface 44 of the hook 43 cooperates with the inclined surface 49 of the locking portion 46 to restrict the withdrawal of the hook 43 from the through hole 47 . Thus, the casing 20 and the front panel 30 are connected together.

当需要从壳体20上拆下前面板30时，用力驱使前面板30和壳体20分开。由于斜面44、49的导引，卡钩43会在拆卸力的作用下沿斜面49向通孔47方向运动，并继而退出通孔47，从而无需太大的力就可将前面板30和壳体20分开，并且在拆卸的过程中避免破坏卡钩43或止动件48。When the front panel 30 needs to be detached from the housing 20 , the front panel 30 is forced to separate from the housing 20 . Due to the guidance of the inclined surfaces 44, 49, the hook 43 will move toward the through hole 47 along the inclined surface 49 under the action of the removal force, and then withdraw from the through hole 47, so that the front panel 30 and the shell can be removed without too much force. The body 20 is separated, and the hook 43 or the stopper 48 are prevented from being damaged during the disassembly process.
