[0037] The utility model provides a back plate assembly 101. Figure 1 to Figure 2 This is an embodiment of the present utility model.

[0038] In an embodiment of the utility model, the back panel assembly 101 is applied to a display device 1000, and the back panel assembly 101 includes a back panel 1, and the back panel 1 has a mounting surface 11 and a mounting groove 21, wherein the mounting surface 11 is used to mount the display panel 200, and a notch of the mounting groove 21 is formed on the mounting surface 11, and the mounting groove 21 is used to mount the speaker 102.

[0039] In the technical solution of the present invention, a mounting groove 21 is opened on the mounting surface 11 for mounting the display panel 200, and the notch of the mounting groove 21 is formed on the mounting surface 11, so that the speaker 102 and the display panel 200 can be installed in the mounting groove 21 from the same side of the back plate 1, thereby avoiding the complication of the installation process caused by separately installing the speaker 102 and the display panel 200 on both sides of the back plate 1 of the display device 1000, optimizing the assembly process of the speaker 102, and reducing the difficulty of assembly.

[0040] In order to specifically form the mounting groove 21, in one embodiment, the back panel assembly 101 also includes a speaker rear shell 2, the back panel 1 has the mounting surface 11, the rear side surface 12 facing away from the mounting surface 11, and the avoidance hole 13 penetrating the mounting surface 11 and the rear side surface 12, the speaker rear shell 2 forms an inner groove 24, the speaker rear shell 2 is connected to the rear side surface 12 and the inner groove 24 is connected to the avoidance hole 13, that is, the mounting groove 21 is jointly formed by the avoidance hole 13 and the speaker rear shell 2, and the groove wall of the inner groove 24 forms the groove wall of the mounting groove 21; the avoidance hole 13 provides an avoidance for the speaker 102 to pass through the back panel 1, thereby realizing the installation of the speaker 102 from the side where the mounting surface 11 is located into the speaker rear shell 2.

[0041] To meet the needs of dual-channel display devices, in one embodiment, Figure 1 and Figure 2As shown, the back panel assembly 101 includes two speaker rear shells 2, and the back panel 1 has two avoidance holes 13. The two avoidance holes 13 are respectively arranged near the two side edges of the back panel 1, and each speaker rear shell 2 corresponds to one avoidance hole 13. During assembly, each speaker 102 can be installed with the display panel 200 from the side where the mounting surface 11 is located, through the avoidance hole 13, and installed in the mounting groove 21, thereby reducing the assembly difficulty of the display device 1000 and improving the assembly efficiency.

[0042] In the prior art, since the speaker and the display panel are installed on different sides of the back plate, the speaker needs to pass the wire through the back plate to the side where the display panel is located when wiring, which causes inconvenience to the installation of the speaker, especially when the display device has two speakers, the above defects are more obvious. In one embodiment, a wire accommodating portion is formed on the mounting surface 11, and the wire accommodating portion is located between the two avoidance holes 13 and is used to accommodate the wire of the speaker 102. After optimizing the assembly process of the speaker 102, the assembly process of the speaker 102 is before the display panel 200. After the speaker 102 is assembled into the mounting groove 21, the wire of the speaker 102 is led out through the avoidance hole 13 and the wires of the two speakers 102 are gathered to the mounting surface 11 through the wire accommodating portion. Since the display panel 200 has not yet been assembled, the wiring process has a large operating space and is highly convenient.

[0043] In order to realize the connection between the speaker rear housing 2 and the back plate 1, in one embodiment, Figure 5 The speaker rear shell 2 is made of plastic material, the back plate 1 and the speaker rear shell 2 are an integrated structure, and the integrated connection structure can be that the speaker rear shell 2 is injection molded on the back plate 1. In order to facilitate the production of the speaker rear shell 2, the speaker rear shell 2 is produced independently. In this embodiment, Figure 3 and Figure 4 As shown, the speaker rear shell 2 is connected to the back panel 1 by hot melting. The specific structure is that a plurality of hot melting feet 22 are protruding from the end face of the speaker rear shell 2 facing the back panel 1, and a plurality of welding holes are opened on the back panel 1 corresponding to each of the hot melting feet 22. After each of the hot melting feet 22 is correspondingly inserted into each of the welding holes, hot melting is performed to achieve the connection and fixation between the speaker rear shell 22 and the back panel 1.

[0044] In one embodiment, the speaker rear shell 22 and the back panel 1 are detachably connected, and the specific structure of the detachable connection is not limited, and it can be a snap connection, a threaded connection, etc. When the speaker rear shell 22 and the back panel 1 are detachably connected, it is easier to inspect and replace the speaker 102.

[0045] In a specific embodiment, the back panel 1 is provided with a locking hole passing through the mounting surface 11 and the rear side surface 12, and the speaker rear shell 22 is formed with a threaded hole on the end surface facing the back panel 1, and the back panel assembly 101 also includes a locking screw, and the threaded hole and the locking hole are opposite to each other. The locking screw passes through the locking hole and is threadedly connected to the hole wall of the threaded hole, so that the speaker rear shell 22 is connected to the back panel 1 through the locking screw, thereby realizing a detachable connection between the two.

[0046] The existing speaker rear shell mostly extends to cover the side end of the back plate, which causes a certain degree of material waste. In order to improve the waste of the above-mentioned material use, in one embodiment, as Figure 2 As shown, the outer side wall of the speaker rear shell 2 is arranged near the avoidance hole 13. That is, the speaker rear shell 22 only covers the part for installing the speaker 102 and its periphery, and does not extend to the two side ends of the back plate 1, thereby saving the use of materials. On the other hand, since the speaker rear shell 2 does not extend to the two side ends of the back plate 1, the two ends of the speaker rear shell 2 can be made into the same structure, thereby achieving the commonality between the speaker rear shells 22 of the left and right speakers 102 of the display device 1000.

[0047] The utility model also provides a speaker assembly 100, such as Figures 3 to 5 As shown, the speaker assembly 100 includes a speaker 102 and the back panel assembly 101. The speaker 102 is installed in the installation groove 21, so that the speaker 102 and the display panel 200 are installed from the same side of the back panel 1, which reduces the difficulty of assembly and saves assembly steps. The specific structure of the back panel assembly 101 refers to the above embodiment. Since the speaker assembly 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0048] To specifically implement the installation of the speaker 102 in the installation slot 21, in one embodiment, Figure 3 , Figure 4 as well as Figure 5 As shown, the speaker rear shell 2 has a mounting rod portion 23, and the speaker 102 has a socket portion 201. The mounting rod portion 23 is formed on the bottom wall of the mounting groove 21 and extends toward the groove. The socket portion 201 is socketed and installed on the mounting rod portion 23, thereby realizing the installation of the speaker 102 in the mounting groove 21 of the speaker rear shell 22.

[0049] Specifically, the mounting rod portion 23 includes a first limiting section 231, a mounting section 232 and a second limiting section 233 which are connected in sequence along the bottom wall of the mounting slot 21 pointing to the slot opening, the radius of the first limiting section 231 and the second limiting section 233 being greater than the radius of the mounting section 232, the sleeve portion 201 being sleeved and mounted on the mounting section 232, the sleeve portion 201 being respectively abutted against the first limiting section 231 and the second limiting section 233 so as to determine the installation position of the speaker 102 through the first limiting section 231 and the second limiting section 233 and to limit the speaker 102 from escaping from the mounting slot 21.

[0050] Furthermore, the outer peripheral wall of the second limiting section 233 gradually shrinks along the bottom wall of the installation groove 21 in the direction of the slot opening, so that the sleeve portion 201 of the speaker 102 can pass through the second limiting section 233 and cooperate with the installation section 232. After the installation is completed, the two ends of the sleeve portion 201 in the direction of the bottom wall of the installation groove 21 in the direction of the slot opening are respectively abutted against the first limiting section 231 and the second limiting section 233.

[0051] The utility model also provides a display device 1000, such as Figure 6 As shown, the display device 1000 includes the speaker assembly 100 and a display panel 200, and the display panel 200 is mounted on the mounting surface 11 of the back plate 1. The specific structure of the speaker assembly 100 refers to the above embodiment. Since the display device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
