Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Apparently, the described embodiments are some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, other embodiments obtained by persons of ordinary skill in the art without making creative efforts all belong to the protection scope of the present application.

FIG. 1 is a schematic diagram of current electronic devices using buckle connections. As shown in Figure 1, the buckle and the housing of the electronic device are locked by positional interference, and the reliability of the locking depends on the amount of interference between the buckle and the housing position. FIG. 1 shows two interference quantities K1 and K2 of different sizes for the buckle and housing design, wherein the interference quantity K1 is greater than the interference quantity K2. After the buckle and the shell are locked, if it is to be disassembled, an external force needs to be applied to the shell to deform the shell to eliminate interference; however, since the shell is mostly a rigid structure, the range of deformation that can be produced is limited, so the snap The greater the amount of interference between the buckle and the shell, the worse the detachability, and even damage the shell during disassembly; the smaller the interference between the buckle and the shell, the stronger the detachability, but the lock between the buckle and the shell Reliability is also reduced.

In order to solve the above problems, the present application provides an electronic device, the electronic device includes a housing that is fixedly connected with a buckle structure, and after the housing of the electronic device is fixedly connected with a buckle structure, it can have high reliability at the same time and removable performance. In some embodiments, the electronic device is a large-screen display device (for example: smart TV, smart screen product, social TV, Internet TV, etc.). Fig. 2 is a schematic structural view of the housing of the large-screen display device. As shown in Fig. 2, the housing of the large-screen display device specifically includes a middle frame and a rear case, wherein the display screen of the large-screen display device is fixed on a part of the middle frame side, and the rear shell can be fixed to the other side of the middle frame through a buckle structure. Large-screen display devices are developing in a thinner and larger direction. At present, the width H1 of the middle frame of large-screen display devices is mostly between a few millimeters and more than ten millimeters. For example, some manufacturers make the middle frame of large-screen display devices The width H1 is about 5mm. The smaller the width H1 of the middle frame means the smaller the internal space of the large-screen display device, the more difficult it is to design a complex structure to realize the connection of the shell. Generally speaking, the threaded connection method needs to be along the direction of the width H1 of the middle frame. The threaded holes for screwing in are formed by drafting in the middle frame. However, as the width H1 of the middle frame decreases, the depth of the threaded holes that can be formed in the middle frame will also decrease, which will reduce the reliability of the threaded connection. drop, causing the screw to easily come out of the threaded hole. In addition, the housing of a large-screen display device is usually a thin-walled structure, and the wall thickness of the housing is usually only 1 mm, 2 mm or at most a few mm. In this case, if the housing is connected with a threaded connection, it is easy to The shell is damaged due to improper application of force during screwing in the screw. It can be seen that the threaded connection has been unable to meet the development needs of large-screen display devices, and the use of buckle structures to securely connect the housings of large-screen display devices is the main direction of housing structure design.

In the embodiment of the present application, taking a large-screen display device as an example, the electronic device uses a buckle structure to connect the casing, and a technical solution that can have high reliability and detachable performance at the same time is described in detail. Wherein, for the convenience of describing the technical solution, in the following content, the first casing corresponds to the rear casing of the large-screen display device, and the second casing corresponds to the middle frame of the large-screen display device.
