Detailed Description
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. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. Other embodiments based on the embodiments of the present application and obtained by a person of ordinary skill in the art without any creative effort belong to the protection scope of the present application.
Fig. 1 is a schematic view of a current electronic device using a snap connection. As shown in fig. 1, the buckle and the housing of the electronic device are locked by position interference, and the reliability of the locking depends on the interference amount of the buckle and the housing. Fig. 1 shows two interference quantities K1 and K2 of different sizes for the snap and housing design, wherein the interference quantity K1 is greater than the interference quantity K2. After the buckle and the shell are locked, if the buckle and the shell are to be disassembled, external force needs to be applied to the shell to deform the shell so as to eliminate interference; however, since the housing is mostly of a rigid structure and the deformation range that can be generated is limited, the larger the interference amount between the buckle and the housing is, the poorer the detachability is, and even the housing is damaged in the disassembly process; the smaller the amount of interference of the buckle with the housing, the stronger the detachability, but the locking reliability of the buckle and the housing is also weakened.
In order to solve the above problem, the present application provides an electronic device, which includes a housing that is fixedly connected by using a snap structure, and after the housing of the electronic device is fixedly connected by using the snap structure, the electronic device can have high reliability and detachable performance at the same time. In some embodiments, the electronic device is a large screen display device (e.g., smart television, smart screen product, social television, internet television, etc.). Fig. 2 is a schematic structural diagram of a housing of a large-screen display device, and as shown in fig. 2, the housing of the large-screen display device specifically includes a middle frame and a rear shell, wherein a display screen of the large-screen display device is fixed to one side of the middle frame, and the rear shell may be fixed to the other side of the middle frame through a buckle structure. Large-screen display devices are being developed to be thinner and larger, and currently, the width H1 of the middle frame of the large-screen display device is between several millimeters and ten and several millimeters, for example, some manufacturers have made the width H1 of the middle frame of the large-screen display device about 5 mm. The smaller the middle frame width H1, the smaller the inner space of the large-screen display device, the more difficult it is to design a complicated structure to connect the housings, and in terms of the generally adopted threaded connection, it is necessary to form a threaded hole for screwing in a screw in the middle frame by drawing in the direction of the middle frame width H1, however, as the middle frame width H1 is reduced, the depth of the threaded hole that can be formed in the middle frame is also reduced, which may reduce the reliability of the threaded connection, resulting in that the screw is easily removed from the threaded hole. In addition, the housing of the large-screen display device is usually of a thin-wall structure, and the wall thickness of the housing is usually only 1 mm, 2 mm or at most a few mm, in which case, if the housing is connected by using a threaded connection, the housing is easily damaged by improper force application during screwing in the screw. Therefore, the threaded connection cannot meet the development requirement of the large-screen display device, and the fastening structure is used for fixedly connecting the shell of the large-screen display device and is the main direction of the design of the shell structure.
The embodiment of the application takes a large-screen display device as an example, the electronic device is connected with the shell by using the buckle structure, and the technical scheme with higher reliability and detachability can be specifically explained. For convenience of describing the technical solution, in the following description, the first housing corresponds to a rear housing of the large-screen display device, and the second housing corresponds to a middle frame of the large-screen display device.

As shown in fig. 11, the connecting portion 352 and the retaining portion 353 are integrally formed, and the connecting portion 352 and the retaining portion 353 gradually move away from the first side 110 and approach the second side 230 in the opposite direction along G; the distance between one end of the retaining portion 353 away from the first side 110 and the first side 110 in a free extension state without being subjected to an external force is L3, and the distance between the first side 110 and the second side 230 is L4. The distance L3 is greater than the distance L4, so that when the second housing 200 is snap-fitted to the first side 110, the retaining portion 353 forms an interference fit with the second side 230, and the interference is Δ L2. The retaining portion 353 is pressed by the second side 230 to deform toward the first side 110, so that the retaining portion 353 can apply a pressure F2 generated by the deformation to the second side 230, and the end of the retaining portion 353 is tightly attached to the second side 230 under the action of the pressure F2. Therefore, when the first and second housings 100 and 200 are separated from each other in the direction GWhen the first casing 100 and the second casing 200 are in a state of being separated from each other, the stopping portion 353 interferes with the protrusion portion 250 along the direction G to lock the second casing 200, so that the first casing 100 and the second casing 200 are restricted from moving relative to each other.
Fig. 12 is a sectional view of the electronic apparatus provided in the first embodiment of the present application, taken along the direction a of the connection portion 352 and the detachment portion 351. As shown in fig. 12, the connecting portion 352 and the detaching portion 351 are an integral structure, and the connecting portion 352 gradually moves away from the first side edge 110 and approaches the second side edge 230 along the direction B; the detaching part 351 is gradually close to the first side 110 and far away from the second side 230 along the direction B, and the detaching part 351 is in contact with the first side 110 at one end far away from the connecting part 352; thus, the detaching portion 351, the second side edge 230 and the protruding portion 250 enclose a wedge-shaped cavity 400, i.e., a dotted-shaded area in fig. 10, in the gap between the first side edge 110 and the second side edge 230. There is also a gap between the first side 110 and the protrusion 250 to allow the wedge-shaped cavity 400 to communicate with the outside of the electronic device.
Fig. 13 is a schematic view of an electronic device detachment housing according to a first embodiment of the present application. As shown in fig. 13, the disassembling of the second housing 200 includes 3 steps in total. Step 1: a removal tool 900 having a flat shape (e.g., a pry blade, a pry bar, a driver in a straight line, etc.) is used to extend into wedge-shaped cavity 400 from the gap between first side 110 and boss 250. Step 2: rotating the detaching tool 900 counterclockwise in fig. 11 with the protruding portion 250 as a fulcrum to pry the connecting portion 352 and the detaching portion 351 to deform toward the first side 110; because the detaching portion 351, the connecting portion 352 and the retaining portion 353 are integrated, when the connecting portion 352 deforms, the retaining portion 353 can be driven to move toward the first side 110, and meanwhile, the second side 230 also deforms toward the direction away from the first side 110 under the action of the detaching tool 900, so that the distance between the protruding portion 250 and the first side 110 increases; thus, the stopper 353 can be disengaged from the state of being caught by the boss 250, and the stopper 353 interferes with the boss 250 in the position along the direction G and is released. And step 3: the first and second housings 100 and 200 are detached in the G direction.
The technical scheme provided by the first embodiment of the application has the following beneficial effects:
first, the retaining portion 353 and the second side 230 form an interference fit, so that the end of the retaining portion 353 is tightly attached to the second side 230, and the retaining portion 353 interferes with the protrusion 250 along the direction G to lock the second housing 200, thereby limiting the relative movement between the first housing 100 and the second housing 200, and preventing the first housing 100 and the second housing 200 from being separated from each other. The detaching portion 351, the second side 230 and the protruding portion 250 form a wedge-shaped cavity 400 in the gap between the first side 110 and the second side 230, and the wedge-shaped cavity is communicated with the outside of the electronic device through the gap between the first side 110 and the protruding portion 250; the wedge-shaped cavity 400 can provide an operation space for the dismounting tool 900, an operator only needs to extend the dismounting tool 900 into the wedge-shaped cavity 400, the prying connection portion 352 and the dismounting portion 351 deform in the direction close to the first side edge 110, and then the stopping portion 353 can be driven to move in the direction close to the first side edge 110, and meanwhile, the second side edge 230 also deforms in the direction away from the first side edge 110 under the action of the dismounting tool 900, so that the distance between the protruding portion 250 and the first side edge 110 is increased; thus, the interference of the position of the stopping portion 353 along the direction G with the boss portion 250 is released, and the first casing 100 and the second casing 200 are successfully detached.
In addition, since the detaching part 351 can be pried by the detaching tool 900 to eliminate the interference between the retaining part 353 and the boss 250 in the first embodiment of the present application, there is no concern that the first housing 100 cannot be detached due to an excessive interference amount between the buckle 300 and the first housing 100 when the buckle 300 and the first housing 100 are designed.
