DETAILED DESCRIPTION

[0045] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0046] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the contour of each component itself. The terms "first" and "second" are used to distinguish one element from another element and do not have order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.

[0047] According to an exemplary embodiment of the present disclosure, a housing assembly is provided, referring to Figures 1 to 6 As shown in the figure, the shell assembly includes at least two shells 1, a hinge structure 2 and a first dustproof part 3. The two adjacent shells 1 are hinged together by the hinge structure 2. The shell assembly has an unfolded state. In the unfolded state, the two adjacent shells 1 are abutted together by the first dustproof part 3.

[0048] It should be noted that the housing 1 may be a structure such as a middle frame or a battery cover, and the embodiment of the present disclosure does not specifically limit the type of the housing 1.

[0049] Through the above technical solution, in the housing assembly provided by the present disclosure, when the housing assembly is in the unfolded state, since two adjacent housings 1 are abutted together by the first dustproof member 3, the first dustproof member 3 can fill and block the gap that may exist between the two housings 1, and then when the housing assembly is in the unfolded state, the first dustproof member 3 can prevent external dust from entering the terminal through the gap. That is, the housing assembly of the present disclosure can solve the technical problem that external dust may enter the terminal.

[0050] It should be noted that the present disclosure does not limit the specific location of the first dustproof member 3. For example, the first dustproof member 3 can be disposed on the housing 1 or on the hinge structure 2. This disclosure will be described in detail in the following embodiments.

[0051] In the exemplary embodiment of the present disclosure, referring to Figures 1 to 4As shown in , the shell 1 may have a side portion 11, and the side portion 11 of at least one of the two adjacent shells 1 may be provided with a first dustproof piece 3, and in the unfolded state, the two adjacent side portions 11 are butted together by the first dustproof piece 3. Here, in the process of switching the shell assembly from the folded state to the unfolded state, the two adjacent shells 1 will gradually approach each other, and in the unfolded state, the two side portions 11 of the two adjacent shells 1 are adjacent, at this time, the two adjacent side portions 11 may be butted together by the first dustproof piece 3, thereby, the first dustproof piece 3 can fill and block the gap that may exist between the two adjacent side portions 11, thereby preventing external dust from entering the terminal through the gap.

[0052] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown in , the side portions 11 of two adjacent shells 1 can be provided with a first dustproof piece 3. In the expanded state, the first dustproof piece 3 on one of the two adjacent side portions 11 abuts against the first dustproof piece 3 on the other side portion 11. Here, the first dustproof piece 3 can be made of elastic material, so that in the expanded state, each first dustproof piece 3 has a certain amount of compression. Since the first dustproof pieces 3 between the two adjacent side portions 11 abut against each other, it is more difficult for external dust to enter the interior of the terminal. Therefore, such a setting can improve the sealing effect of the gap between the two adjacent side portions 11, and further prevent external dust from entering the interior of the terminal.

[0053] In some embodiments of the present disclosure, reference Figure 3 As shown in , the side portions 11 of two adjacent shells 1 can be provided with a first dustproof member 3, and each side portion 11 can have a side wall surface 111. In the unfolded state, the first dustproof member 3 on one of the two adjacent side portions 11 abuts against the side wall surface 111 of the other side portion 11. In this way, the two adjacent side portions 11 can form a dustproof structure consisting of at least two pairs of first dustproof members 3 and side wall surfaces 111, so that external dust needs to pass through at least two dustproof structures to enter the interior of the terminal. Therefore, such a setting makes it more difficult for external dust to enter the interior of the terminal.

[0054] In some embodiments of the present disclosure, reference Figure 4 As shown in , the first dust-proof member 3 can be provided on one of the two adjacent side portions 11, and the other side portion 11 has a side wall surface 111. In the unfolded state, the first dust-proof member 3 abuts against the side wall surface 111. In this way, one of the two adjacent side portions 11 can be provided with the first dust-proof member 3, and the other can be not provided with the first dust-proof member 3. Through the abutment between the first dust-proof member 3 and the side wall surface 111, the dust-proof function of the first dust-proof member 3 can also be achieved.

[0055] In some embodiments of the present disclosure, reference Figure 1 , Figure 3 and Figure 4 As shown in , the first dustproof member 3 may have a dustproof surface 31 exposed to the corresponding side edge portion 11, and the dustproof surface 31 may be configured as a plane. Of course, in other embodiments, refer to Figure 2 As shown in , the dustproof surface 31 can also be constructed as a curved surface, and the present disclosure can make adaptive designs for this as needed.

[0056] In some embodiments of the present disclosure, the first dustproof member 3 can be integrally formed with the corresponding side portion 11. In this way, the number of parts of the housing assembly can be reduced, which is convenient for assembling the housing assembly. Of course, in other embodiments, the first dustproof member 3 can also be detachably connected to the corresponding side portion 11, so that the disassembly and replacement of the first dustproof member 3 can be facilitated.

[0057] The above describes a specific implementation of arranging the first dustproof member 3 on the side portion 11 . Of course, the first dustproof member 3 of the present disclosure can also be arranged on the hinge structure 2 .

[0058] For example, in the exemplary embodiment of the present disclosure, referring to Figure 5 As shown in , the hinge structure 2 may have a contact surface 21 that rotates with the housing 1, and the first dustproof member 3 is disposed on the contact surface 21. In this way, during the process of switching the housing assembly from the folded state to the unfolded state, two adjacent housings 1 may gradually approach each other until they are abutted together by the first dustproof member 3. In this way, by disposing the first dustproof member 3 on the contact surface 21, the dustproof function of the first dustproof member 3 may also be realized. Here, the hinge structure 2 may include a shaft cover 22, and the shaft cover 22 may have the above-mentioned contact surface 21, and the present disclosure does not limit this.

[0059] In some embodiments of the present disclosure, reference Figure 5 As shown in , the housing 1 has an open groove 12 arranged toward the contact surface 21. In the unfolded state, the two open grooves 12 of the two adjacent housings 1 together enclose a first receiving groove 10, and the first dustproof member 3 is at least partially arranged in the first receiving groove 10. In this way, the dustproof function of the first dustproof member 3 can be achieved by the abutment between the first dustproof member 3 and the groove wall of the first receiving groove 10. In addition, by the arrangement of the first receiving groove 10, it can be ensured that the first dustproof member 3 is arranged in the first receiving groove 10, thereby ensuring the stable dustproof of the first dustproof member 3.

[0060] In an exemplary embodiment of the present disclosure, the first dustproof member 3 is at least partially made of an elastic material. In this way, in the unfolded state, the first dustproof member 3 has a certain amount of compression. Thus, by utilizing the compression of the first dustproof member 3 itself, it is possible to effectively ensure that the first dustproof member 3 blocks the gap between two adjacent shells 1, thereby improving its own dustproof effect. Here, according to some embodiments, the compression amount of the first dustproof member 3 can be 0.05mm to 0.25mm, for example, 0.1mm or 0.2mm, and the present disclosure does not limit this. In addition, according to some embodiments, the first dustproof member 3 can be made of materials such as silicone and elastic rubber, and the present disclosure does not limit this.

[0061] In the exemplary embodiment of the present disclosure, referring to Figures 1 to 4 as well as Figures 6 to 9 As shown in , the housing 1 and / or the hinge structure 2 may be provided with a second dustproof member 4, which is provided between the housing 1 and the hinge structure 2. When the housing 1 rotates relative to the hinge structure 2, the second dustproof member 4 provided on the housing 1 remains in contact with the hinge structure 2, and / or the second dustproof member 4 provided on the hinge structure 2 remains in contact with the housing 1. In this way, when the housing 1 is provided with the second dustproof member 4, the second dustproof member 4 can remain in contact with the hinge structure 2 during the rotation of the housing 1, that is, the second dustproof member 4 always remains in contact with the hinge structure 2, so that during the rotation of the housing 1, the second dustproof member 4 always maintains a certain overlap with the hinge structure 2, thereby, when the housing assembly is in the unfolded state, the folded state, and when switching between the unfolded state and the folded state, the second dustproof member 4 can fill and block the gap between the hinge structure 2 and the housing 1, so that by providing the second dustproof member 4, external dust can be prevented from entering the terminal through the gap between the housing 1 and the hinge structure 2. Similarly, when the hinge structure 2 is provided with a second dustproof part 4, during the rotation of the shell 1, the second dustproof part 4 can remain in contact with the shell 1, thereby preventing external dust from entering the terminal through the gap between the shell 1 and the hinge structure 2.

[0062] In some embodiments of the present disclosure, reference Figures 1 to 4 as well as Figure 6As shown in , a second dustproof piece 4 can be provided on the shell 1. In the unfolded state, the second dustproof piece 4 on one of the two adjacent shells 1 can abut against the second dustproof piece 4 on the other shell 1. In this way, the first dustproof piece 3 and the second dustproof piece 4 of the present disclosure can cooperate with each other to achieve two-level dustproofing of the terminal. Specifically, in the unfolded state, the two shells 1 are abutted together by the first dustproof piece 3. At this time, the first dustproof piece 3 can constitute the primary dustproof structure of the shell assembly; since the second dustproof piece 4 is arranged between the shell 1 and the hinge structure 2, the second dustproof piece 4 is closer to the inside of the terminal than the first dustproof piece 3. Therefore, the two second dustproof pieces 4 can constitute the secondary dustproof structure of the shell assembly. Therefore, even if external dust passes through the first dustproof piece 3, the present disclosure can also use the two second dustproof pieces 4 to block the external dust. Therefore, by designing the two-stage dustproof structure of the shell assembly, external dust can be effectively prevented from entering the terminal.

[0063] In some embodiments of the present disclosure, reference Figures 1 to 4 as well as Figure 6 As shown in , the second dustproof member 4 can be arranged on the side of the housing 1 close to the hinge structure 2 and close to the side edge portion 11 of the housing 1. In this way, on the one hand, the second dustproof member 4 can be made closer to the hinge structure 2, which is conducive to the abutment between the second dustproof member 4 and the hinge structure 2; on the other hand, the second dustproof member 4 is arranged close to the side edge portion 11, which is conducive to the abutment of the second dustproof member 4 between two adjacent side edges 11 in the unfolded state.

[0064] Optionally, refer to Figures 1 to 4 as well as Figure 6 As shown in , the housing 1 may have a second accommodating groove 13 for arranging the second dustproof member 4, the opening of the second accommodating groove 13 faces the hinge structure 2, and the second accommodating groove 13 is located near the side edge 11 of the housing 1. In this way, the opening of the second accommodating groove 13 faces the hinge structure 2, which is conducive to the abutment of the second dustproof member 4 with the hinge structure 2; the second accommodating groove 13 is arranged to be located near the side edge 11 of the housing 1, which is conducive to the abutment of the second dustproof member 4 between two adjacent side edges 11 in the unfolded state.

[0065] In some embodiments of the present disclosure, reference Figures 6 to 8As shown in, a second dustproof piece 4 can be provided on the shell 1, and the hinge structure 2 can have a contact surface 21 that rotates with the shell 1, and the contact surface 21 includes: a first surface 211 and a second surface 212, and the shell assembly has an unfolded state and a folded state that can be switched with each other; in the unfolded state, the shell 1 abuts against the first surface 211 through the second dustproof piece 4; in the folded state, the shell 1 abuts against the second surface 212 through the second dustproof piece 4, wherein one of the first surface 211 and the second surface 212 is constructed as a plane, and the other is constructed as an arcuate surface. That is to say, the first surface 211 and the second surface 212 are constructed as surfaces of different shapes, and one of them is constructed as a curved surface. Here, by utilizing the abutment between the second dustproof piece 4 and the first surface 211 or the abutment between the second surface 212, real-time dustproofing of the second dustproof piece 4 during the rotation of the shell 1 can be achieved. Moreover, the second dustproof piece 4 can also abut against the curved surface, thereby adapting to the dustproofing of the gap between the hinge structure 2 with the curved surface and the shell 1. Therefore, the second dustproof piece 4 disclosed in the present invention has good dustproofing effect and strong adaptability.

[0066] In some embodiments of the present disclosure, reference Figure 6 and Figure 7 As shown in , the second surface 212 can be configured as an arc-shaped surface, and the second dustproof member 4 can include: at least two elastic parts 41; in the folded state, the at least two elastic parts 41 are in contact with the second surface 212. In this way, the dustproof effect of the second dustproof member 4 in the folded state can be ensured by the contact between the at least two elastic parts 41 and the second surface 212.

[0067] Optionally, refer to Figure 6 and Figure 7 As shown in , the heights of at least two elastic parts 41 can be different. Thus, in the folded state, by utilizing the different heights of at least two elastic parts 41, each elastic part 41 can have a different compression amount when abutting against the second surface 212, thereby each elastic part 41 can abut against the second surface 212.

[0068] Optionally, refer to Figure 6 and Figure 7 As shown in the figure, at least two elastic parts 41 can be arranged at intervals, so that when the shell assembly is switched from the folded state to the unfolded state, the dust between the two adjacent elastic parts 41 can be pushed to the middle position of the hinge structure 2 by the elastic part 41 located innerward, thereby facilitating the user to clean the dust on the hinge structure 2.

[0069] In some embodiments of the present disclosure, reference Figure 8As shown in , the second surface 212 is configured as an arc surface, the housing 1 has a second accommodating groove 13 for arranging the second dustproof member 4, and the bottom wall surface 131 of the second accommodating groove 13 is configured as an arc surface with the same curvature as the second surface 212. In this way, in the folded state, the compression amount of each part of the second dustproof member 4 can be kept basically consistent, thereby making the second dustproof member 4 evenly stressed.

[0070] In some embodiments of the present disclosure, reference Figures 1 to 4 as well as Figures 6 to 8 As shown in , the hinge structure 2 may include a shaft cover 22, and the shaft cover 22 may have the above-mentioned contact surface 21, that is, the above-mentioned second dustproof member 4 may be arranged between the shaft cover 22 and the housing 1, and the present disclosure does not limit this.

[0071] In some embodiments of the present disclosure, the first dustproof member 3 may be an integral structure, and the first dustproof member 3 extends continuously along the length direction of the housing 1. In this way, the blocking area and filling area of ​​the first dustproof member 3 can be increased, further reducing the probability of dust entering the terminal. Of course, in other embodiments, the first dustproof member 3 may be a segmented structure, wherein the first dustproof member 3 includes a plurality of first dustproof segments arranged in sequence along the length direction of the housing 1, and in the unfolded state, two adjacent first dustproof segments of two adjacent first dustproof members 3 can abut against each other.

[0072] In some embodiments of the present disclosure, reference Fig. 9 As shown in , the second dustproof member 4 can be an integral structure, and the second dustproof member 4 extends continuously along the length direction of the housing 1. In this way, the blocking area and filling area of ​​the second dustproof member 4 can be increased, and the probability of dust entering the terminal can be further reduced. Of course, in other embodiments, the second dustproof member 4 can be a segmented structure, wherein the second dustproof member 4 includes a plurality of second dustproof segments arranged in sequence along the length direction of the housing 1, and each second dustproof segment can abut against the hinge structure 2.

[0073] In some embodiments of the present disclosure, reference Figures 9 to 11As shown in , the shell 1 may be provided with a second dustproof member 4, and the shell assembly may include a positioning member 5, and the shell 1 is rotatably connected to the hinge structure 2 through the positioning member 5, wherein one of the shell 1 and the positioning member 5 is provided with a positioning hole 14, and the other is provided with a positioning portion 51, and the positioning portion 51 is provided in the positioning hole 14 and abuts against the hole wall of the positioning hole 14 on the side close to the hinge structure 2. In this way, on the one hand, through the cooperation of the positioning hole 14 and the positioning portion 51, the shell 1 and the positioning member 5 and the hinge structure 2 can be pre-positioned, and on the other hand, the positioning portion 51 abuts against the hole wall of the positioning hole 14 on the side close to the hinge structure 2, that is, the positioning portion 51 and the positioning hole 14 are unilaterally matched close to the hinge structure 2. Such a design can make the shell 1 close to the hinge structure 2, thereby facilitating the shell 1 to press the second dustproof member 4 onto the hinge structure 2.

[0074] In some embodiments of the present disclosure, reference Fig.11 As shown in , the positioning portion 51 can be constructed as a positioning column. Of course, the positioning portion 51 can also be constructed as a positioning block or other structures, and the present disclosure does not limit this.
