[0065] The screen assembly 14 and the first frame structure 1 can slide relative to each other, which makes installation more convenient. Generally, the screen assembly 14 is used for sliding, and the screen assembly 14 is more flexible to operate and more convenient for users to operate.

[0066] In some embodiments, one of the screen assembly 14 and the first frame structure 1 is provided with a mating groove 17 and the other is provided with a sliding limit block 18, and the sliding limit block 18 is slidably engaged with the mating groove 17. That is to say, a mating groove 17 can be set in the screen assembly 14, and a sliding limit block 18 can be set in the first frame structure 1, or a sliding limit block 18 can be set in the screen assembly 14, and a mating groove 17 can be set in the first frame structure 1. The sliding installation of the screen assembly 14 and the first frame structure 1 can be achieved through the sliding engagement of the sliding limit block 18 and the mating groove 17.

[0067] As shown in Figures 4 and 5, in this embodiment, the screen assembly 14 is set as a sliding limit block 18, and a matching groove 17 is set in the first frame structure 1. During the specific design, the slider limit block is provided on the inner side surface of the screen assembly 14 and protrudes from the inner surface of the screen assembly 14. The matching groove 17 is provided on the side of the first frame structure 1 close to the screen assembly 14 and is recessed into the surface of the first frame structure 1. The sliding limit block 18 is matched with the matching groove 17. During actual installation, the sliding limit block 18 is slid into the inside of the matching groove 17 to complete the sliding installation of the screen assembly 14 and the first frame structure 1, and the installation is very convenient.

[0068] The screen assembly 14 and the first frame structure 1 may be installed using the above-mentioned sliding limit and plug-in positioning methods, or may be installed using common methods such as gluing, ultrasonic welding, and bolt connection.

[0069] In some embodiments, the mating groove 17 includes a connecting guide sub-groove 171 and a limiting sub-groove 172 , the screen assembly 14 is provided with a first positioning hole 141 , and the first frame structure 1 is provided with a second positioning hole 19 .

[0070] Among them, as shown in Figure 4, the matching groove 17 includes a guide sub-groove 171 and a limiting sub-groove 172. The guide sub-groove 171 is connected to the limiting sub-groove 172, and the guide sub-groove 171 and the limiting sub-groove 172 are set in different directions. The guide sub-groove 171 can be horizontal and the limiting sub-groove 172 is vertical. As shown in Figure 5, the direction of the sliding limit block 18 is the same as the guide sub-groove 171, and the width and thickness of the sliding limit block 18 are matched with the groove width and groove depth of the guide sub-groove 171, so as to facilitate the sliding cooperation of the sliding limit block 18 with the guide sub-groove 171 and the limiting sub-groove 172.

[0071] Among them, the sliding limit block 18 is suitable for sliding into the guide sub-slot 171, and after sliding into the limit sub-slot 172, the first positioning hole 141 and the second positioning hole 19 are opposite, and the positioning member 51 is sequentially inserted into the first positioning hole 141 and the second positioning hole 19.

[0072] As shown in Figures 4 and 5, the screen assembly 14 is provided with a first positioning hole 141, and the first frame structure 1 is provided with a second positioning hole 19. The sizes of the first positioning hole 141 and the second positioning hole 19 can be set to be the same. When the screen assembly 14 is installed with the first frame structure 1, after the screen assembly 14 is close to the first frame structure 1, the sliding limit block 18 of the screen assembly 14 is moved along the guide sub-groove 171 to slide into the limit sub-groove 172. At this time, the positioning member 51 is sequentially inserted into the first positioning hole 141 and the second positioning hole 19 to complete the installation of the positioning member 51, and the screen assembly 14 and the first frame structure 1 can be installed. The installation is simple, easy to operate, and firmly installed.

[0073] A bumper strip 52 is provided on the rear side of the first frame structure 1 to provide a buffer and prevent collisions. When the audio / video player 100 is using the sound module, which may cause vibrations, the first frame structure 1 and the second frame structure 2 are located close together, and thus, the first frame structure 1 and the second frame structure 2 may collide with each other. The bumper strip 52 can absorb the vibrations generated by such a collision. If the bumper strip 52 is positioned at the position of the positioning member 51, it can further prevent the positioning member 51 from falling off.

[0074] In this embodiment, the positioning member 51 can be manually plugged in. In other embodiments, the positioning member 51 can also be configured as an integral structure with the first frame structure 1 and can be designed according to needs.

[0075] In some embodiments, the sliding limit block 18 is adapted to slide into the guide sub-slot 171 along a first direction, and slide from the guide sub-slot 171 into the limit sub-slot 172 along a second direction, wherein the first direction is perpendicular to the second direction.

[0076] Specifically, the guide sub-groove 171 is distributed horizontally, and the limiting sub-groove 172 is distributed vertically. The first direction can be set as horizontal and the second direction as vertical, that is, the first direction and the second direction are perpendicular to each other, wherein the guide sub-groove 171 plays a sliding guide role, and the limiting sub-groove 172 plays a limiting role. During actual installation, as shown in Figures 6-10, the screen assembly 14 is first moved horizontally so that the sliding limit block 18 slides into the guide sub-groove 171 horizontally, and then slides vertically into the limiting sub-groove 172, so that the sliding limit block 18 is vertically and horizontally limited by the limiting sub-groove 172. As shown in Figure 11, the installation of the screen assembly 14 and the first frame structure 1 can be completed.

[0077] Therefore, the guide sub-groove 171 and the limiting sub-groove 172 are set to be perpendicular to each other, making the installation of the sliding limit block 18 more convenient and facilitating the limiting of the sliding limit block 18, ensuring that the matching groove 17 and the sliding limit block 18 are installed reliably, and the structure is simple and easy to manufacture.

[0078] In some embodiments, there are multiple matching grooves 17 and multiple sliding limit blocks 18, and the multiple matching grooves 17 are matched with the multiple sliding limit blocks 18 in a one-to-one correspondence.

[0079] Specifically, as shown in Figure 4, there are multiple matching grooves 17, and the multiple matching grooves 17 can be distributed along the circumference of the first frame structure 1 and are evenly spaced apart. As shown in Figure 5, there are also multiple sliding limit blocks 18, and the multiple matching grooves 17 can be distributed along the circumference of the screen assembly 14 and are evenly spaced apart. The multiple matching grooves 17 and the multiple sliding limit blocks 18 are set in a one-to-one correspondence. In this way, when the screen assembly 14 is connected to the first frame structure 1, the multiple matching grooves 17 and the multiple sliding limit blocks 18 are slidably matched in a one-to-one correspondence, and multiple sets of sliding fits can be realized on the screen assembly 14 and the first frame structure 1, making the installation of the screen assembly 14 and the first frame structure 1 more reliable, and the installation of multiple sets of sliding fits can make the appearance of the screen assembly 14 and the first frame structure 1 regular after installation, thereby improving the user experience.

[0080] The number of the matching grooves 17 and the sliding limit blocks 18 can be designed according to the actual structure, as long as the installation is simple and reliable.

[0081] In some embodiments, there are multiple mating grooves 17 and multiple positioning members 51 , and the multiple mating grooves 17 and the multiple positioning members 51 are spaced apart and distributed along the circumferential edge of the screen assembly 14 .

[0082] Specifically, as shown in Figures 4 and 5, the second positioning holes 19 are provided in a plurality, the corresponding positioning members 51 are also provided in a plurality, the matching grooves 17 are provided in a plurality, the plurality of matching grooves 17 and the plurality of second positioning holes 19 are provided in a plurality and can be distributed spaced apart along the circumferential edge of the screen assembly 14, and the first positioning holes 141 are provided in a plurality and the plurality of first positioning holes 141 can be distributed spaced apart along the circumferential edge of the screen assembly 14. In this way, multiple sets of sliding fit installations and multiple sets of positioning plug-ins can be formed, so that the screen assembly 14 and the first frame structure 1 are installed more firmly and reliably to ensure the stability of the screen assembly 14 during operation. Among them, the number of positioning members 51 can be designed according to actual needs.

[0083] In some embodiments, a detachable fixing plate 141 is provided on a side of the first frame structure 1 facing away from the second frame structure 2 , and the screen assembly 14 is fixedly mounted on the fixing plate 141 .

[0084] Specifically, as shown in FIG15 , the first frame structure 1 is provided with a fixing plate 141 on the side facing away from the second frame structure 2. The screen assembly 14 is fixedly connected to the fixing plate 141, that is, the fixing plate 141 can be arranged between the first frame structure 1 and the screen assembly 14. The fixing plate 141 can be constructed as a square flat plate, which is detachably connected to the first frame structure 1, so that the fixing plate 141 and the first frame structure 1 can be connected and fixed, and can be easily disassembled and maintained. In the actual design, the first frame structure 1 is provided with a mounting groove 121. The mounting groove 121 is recessed toward the second frame structure 2 on the side close to the fixing plate 141. The shape and depth of the mounting groove 121 match the shape and thickness of the fixing plate 141, which facilitates the installation of the fixing plate 141. The screen assembly 14 is connected to the side of the fixing plate 141 facing away from the first frame structure 1. The two are fixedly connected to achieve the installation of the screen assembly 14. In this way, an indirect connection between the screen assembly 14 and the first frame structure 1 is also achieved.

[0085] Therefore, by providing a fixing plate 141 between the first frame structure 1 and the screen assembly 14, the structural strength of the first frame structure 1 can be improved, the reliability of the installation of the screen assembly 14 is ensured, and the strength of the overall structure is improved.

[0086] In some embodiments, the first frame structure 1 is provided with a connecting column 122, and the fixing plate 141 is provided with a connecting hole 1411. The connecting column 122 is passed through the connecting hole 1411 and is connected to the connecting member 1412. At least a portion of the connecting member 1412 is pressed against the side of the fixing plate 141 away from the first frame structure 1.

[0087] Specifically, the first frame structure 1 is provided with a connecting column 122 on the side close to the fixing plate 141. The connecting column 122 can be set to a cylindrical shape. The protruding height of the connecting column 122 is less than the thickness of the fixing plate 141.
