Detailed Description

The technical solutions of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

The screen assembly structure that this disclosure first aspect provided is suitable for the smart machine of screen subassembly and casing fixed assembly, for example intelligence wearing equipment (like intelligent wrist-watch, intelligent bracelet), smart mobile phone etc.. One feature of these devices is that interactive operations are performed through the screen, so that the screen provides the user with functions such as information display, touch operation, and the like. The screen occupation ratio is the ratio of the content display area of the screen to the whole screen area, and the high screen occupation ratio has a better visual display effect and brings better interactive experience for users.

For example, taking a smart band in a smart wearable device as an example, fig. 1A to 3 show an assembly structure of a smart band main body part in the prior art. The case 200 is a bottom case of the bracelet, and is a substantially frame structure with an open top, the open end forms a connecting portion 210, and the screen assembly 100 is fixedly mounted at the connecting portion 210. The inside electrical part that provides the bracelet function that is equipped with of casing 200, components and parts such as treater, sensor, the electrical part of the equipment of this disclosure does not relate to the improvement, does not describe here again.

As shown in fig. 1A, 1B, and fig. 2A and 2B, when the screen assembly 100 is assembled with the housing 200, the edge of the screen assembly 100 is provided with a first supporting step 110 that surrounds one turn, and similarly, the connecting portion 210 of the housing 200 is provided with a second supporting step 211 that surrounds one turn. The first support step 110 has a slightly larger diameter than the second support step 211, so that the screen assembly can be supported on the connection part 210. After the screen assembly 100 is assembled to the housing 200, the structure in the length and width directions may be as shown in fig. 1B and 2B.

The fixation between the screen assembly 100 and the housing 200 may be achieved by means of adhesion, i-ring, etc. The adhesion means that the screen assembly 100 is adhered to the housing 200 by means of dispensing, for example, at a contact portion of the screen assembly 100 and a supporting step of the housing 200.

In this example, the screen assembly 100 and the housing 200 are fixedly coupled by the i-ring seal 30. The i-ring is a seal ring having a straight bar-shaped cross section and is made of a flexibly deformable elastomer material, such as hytrel (marine green). In the prior art, as shown in fig. 1A and 1B, an i-ring assembly structure of the screen assembly 100 is that a sealing ring 30 is first disposed on a second supporting step 211 of a housing 200, and when the screen assembly 100 is installed, a side surface of the screen assembly 100 is in transverse interference fit with the sealing ring 30 and a side wall of a connecting portion 210, and the sealing ring 30 is extruded to be flexibly deformed, so that the screen assembly 100 is fixedly assembled. The screen assembly 100 is fixed through the i-ring, and compared with the i-ring which is fixed through bonding, the i-ring is fixed through lateral interference and is not needed to be glued, so that the contact area between the screen assembly 100 and the supporting step of the shell 200 can be reduced to a certain extent, and the i-ring provides better waterproof and dustproof effects.

After the screen assembly 100 is fixedly assembled, the supporting area of the screen assembly 100 and the supporting step of the housing 200 cannot display contents, so that a "black edge" is formed. For example, as shown in fig. 3, due to the interference of the screen assembly 100 and the supporting step surrounding the casing 200, the supporting area 400 does not display contents, and when the bracelet works, the periphery of the screen appears as a circle of "black edge", which results in a low screen occupation ratio of the screen, and the presence of the "black edge" affects the user's appearance and the user experience is poor.

In order to solve the above-mentioned defects in the prior art, the embodiments of the present disclosure provide a screen assembling structure capable of increasing a screen occupation ratio. In some embodiments, the screen assembling structure of the present disclosure includes a housing 200 and a screen assembly 100, the housing 200 has a connecting portion 210 for assembling the screen assembly, a first supporting step 110 is disposed on the screen assembly 100 at a position partially surrounding a screen, a second supporting step 211 corresponding to the first supporting step 110 is disposed on the connecting portion 210, and the first supporting step 110 abuts against the second supporting step 211 in an assembling state of the screen assembly 100 and the housing 200.

The main inventive concept of the disclosed assembly structure lies in: the supporting step structure surrounding the screen is improved to be that the supporting steps are arranged at only one part of the edge of the screen, for example, the supporting steps are arranged at two opposite edges with smaller contact area of the bracelet screen and matched with the supporting steps of the shell, and the other edge positions are used as screen display areas. Since the area of the support step becomes smaller, the display area of the screen increases, so that a higher display screen occupation ratio can be provided for the user.

According to the screen assembly structure, the screen assembly only needs to be provided with the supporting steps at partial positions, and the screen assembly can be used as a screen display area at positions where the supporting steps are not arranged, so that the display screen occupation ratio of a screen is effectively improved.

Fig. 4 to 8 show a specific embodiment of the assembly structure of the present disclosure, in which the smart device still takes the smart bracelet in the smart wearing device as an example.

The screen assembly 100 of the bracelet is an oblong (racetrack-shaped) screen, in this embodiment, first supporting steps 110 are symmetrically arranged on two arc-shaped edges of the screen assembly 100, and the positions of the screen assembly 100 except the first supporting steps 110 are all used as display areas of the screen. On the connecting portion 210 of the housing 200, second supporting steps 211 are also provided at two arc-shaped sides of the oblong circle, and the first supporting step 110 has a larger diameter than the second supporting step 211.

After the screen assembly 100 is assembled with the housing 200, the structure of the screen assembly 100 at the position of the supporting step is as shown in fig. 7A and 7B, and at the position of the two arc-shaped edges of the screen assembly 100, the first supporting step 110 of the screen assembly 100 is supported at the second supporting step 211 of the connecting portion 210, thereby providing support for the screen assembly 100 in the vertical direction. While the structure in other positions is shown in fig. 6A and 6B, it can be seen that there is no support structure between the screen assembly 100 and the housing 200 on the straight edge.

As shown in fig. 8, the assembly effect of the present embodiment is that a supporting area 400 formed by the supporting steps of the screen assembly 100 and the housing 200 is a "black edge" of the screen display. It can be seen that the screen display of the embodiment has only "black edges" on two arc edges, and does not have "black edges" on straight edges, compared with the example of fig. 3, the display screen occupation ratio is greatly improved, and better visual effect and interactive experience are brought.

In the embodiment of the present disclosure, the screen assembly 100 and the housing 200 may be fixed by various fixing connection methods, such as adhesion, i-ring, and the like. In the embodiment of the present disclosure, the area of the supporting step between the screen assembly 100 and the housing 200 is small, and if the bonding is adopted, the bonding area is small, so that there is a risk of screen coming off, and meanwhile, the waterproof and dustproof sealing problems are considered. Therefore, to improve the stability of the screen assembly, in some embodiments, the housing 200 of the screen assembly 100 is fixedly assembled by an elastomer sealing ring. The elastomer sealing ring is a sealing ring which is made of elastomer material and has flexible deformation capacity, for example, an i-ring made of hytrel, tpu and other materials.

In the present embodiment, further considering that the conventional i-ring is in a straight strip shape, for example, the i-ring with a straight strip shape in the cross section in the example of fig. 1A is adopted as the sealing ring 30, and in the unsupported portion, since the screen assembly 100, the i-ring, and the housing 200 have no limit structure in the vertical direction, the screen assembly 100 and the i-ring may be separated under the severe collision and extrusion environment. Therefore, in order to further improve the stability of screen assembly, the disclosed embodiments provide a novel i-ring assembly structure.

As shown in fig. 5A and 5B, in the present embodiment, the screen assembly 100 is fixedly assembled with the housing 200 by a novel i-ring seal 300, and the connecting portion 210 of the housing 200 is provided with an assembling step 212 engaged with the i-ring seal 300. When the screen assembly 100 is assembled with the connection part 210, the i-ring 300 may be first assembled on the assembly step 212 of the connection part 210, and then the screen assembly 100 may be assembled.

On the outer side wall of the i-ring seal 300, a lug 310 extending toward the outside is formed. Meanwhile, a groove 213 which is matched with the shape of the lug 310 is formed on the wall surface of the connecting part 210 matched with the i-ring sealing ring 300. As shown in fig. 5B, when the i-ring 300 is assembled on the assembly step 212, the lug 310 and the groove 213 are engaged with each other, so that the i-ring 300 and the screen assembly 100 are limited in the vertical direction, the i-ring 300 and the screen assembly 100 are effectively prevented from falling off in the vertical direction, and the assembly stability of the screen assembly 100 is further improved.

It should be noted that, in the present embodiment, the side of the assembled i-ring 300, which is not provided with the lug 310, should be flush with the inner edge of the assembly step 212, or slightly protrude from the inner edge of the assembly step 212, so that the screen assembly 100 achieves sealing after the i-ring 300 is interference-assembled with the housing 200, and there is no "black edge" on the edges of the straight edges on both sides. It is understood that, in other embodiments, in order to avoid the interference fit between the screen assembly 100 and the i-ring seal 300, the assembly step 212 may affect the display area of the screen, so that a "black edge" is formed on the two sides of the screen, and the support structure of both the assembly step 212 and the i-ring seal 300 may be completely located outside the i-ring seal 300. For example, the assembly step 212 is an annular groove opened on the inner wall of the connection portion 210, the lug 310 of the i-ring seal 300 is clamped in the annular groove to form a support, and the main body of the i-ring seal 300 is suspended, so that when the inner side of the i-ring seal 300 is in interference fit with the screen assembly 100, the assembly step 212 does not affect the display area of the screen.

With reference to fig. 5B, in the present embodiment, a chamfer 320 is formed at one end of the inner side wall of the i-ring 300, and the chamfer 320 enables the end face of the assembled i-ring 300 to form an expansion structure, thereby facilitating the assembly of the screen assembly 100. The shape of the chamfer 320 may be any shape suitable for implementation, such as a C-angle, a rounded angle, a 45 ° angle, etc., and the present embodiment is not limited thereto.

In some embodiments, in order to further improve the assembly stability of the screen assembly 100, the side wall surface of the screen assembly 100 abutting against the i-ring seal 300 is a frosted surface, and the rough frosted surface increases the friction force between the screen assembly 100 and the side surface of the i-ring seal 300, thereby further improving the assembly stability of the screen.

It should be noted that, in the present embodiment, the fitting step 212 refers to a step for fitting the i-ring seal 300, and the second supporting step 211 refers to a step for fitting the screen assembly 100. To reduce the manufacturing process, two steps may be provided at the same height, for example, as shown in fig. 6B, the connecting portion 210 is provided with only the assembling step 212 at the length side for matching with the i-ring 300. On the arc-shaped side, the connecting portion 210 has a fitting step 212 and a second supporting step 211, which are located at the same height, for example, as shown in fig. 7B, so that the process is more convenient. The machined step is divided into two parts, one part is an assembling step 212 for matching the i-ring seal 300, and the other part is a second supporting step 211 for matching the screen assembly 100. Of course, it should be understood by those skilled in the art that the assembly step 212 and the second support step 211 may be disposed at different heights, and the present disclosure is not limited thereto.

In the assembly structure of the present embodiment, when the screen is assembled, the i-ring 300 is first assembled on the assembly step 212 of the housing connection portion 210, and the lug 310 of the i-ring 300 is engaged with the groove 213, so that the vertical position limitation is formed, and the i-ring 300 is not separated by the engagement of the lug and the groove, so that the assembly is more convenient. At this time, the side of the assembled i-ring 300, on which the lug 310 is not provided, protrudes (is at least flush) with the inner edge of the assembly step 212. Then, the screen assembly 100 is assembled, and the screen assembly 100 is installed in the i-ring seal 300 by hard extrusion to realize interference fit. After the screen assembly 100 is assembled in place, the second supporting step 211 of the shell and the i-ring seal limit the screen assembly 100 in all directions, so that the screen assembly 100 cannot be separated. The assembled display effect of the screen assembly 100 is shown in fig. 8, and the screen display has "black edges" only on the two arc-shaped short edges, and does not have "black edges" on the straight edge, thereby greatly improving the display screen occupation ratio.
