Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display device housing assembly. Background Technology

[0002] An AV bracket is a device that combines audio-video signal interfaces with physical support functions. It is mainly used to fix audio-video signal interfaces to the back panel of display devices. The audio-video signal interfaces are electrically connected to the PCBA (Printed Circuit Board Assembly) board on the back panel to realize audio-video signal input or output.

[0003] Display devices typically have a rear cover that protects electronic components such as the PCBA board from the back panel. The rear cover has an opening to expose the AV receiver bracket. For related technologies, please refer to... Figure 1 and Figure 2 The AV bracket is mounted on the back panel. The periphery of the AV bracket extends into an opening on the rear housing and is fitted with the inner wall of the opening. One inner wall of the opening has a latch that engages with one side of the AV bracket. The side of the opening opposite the latch forms a small flat surface. The problem is that the periphery of the AV bracket is confined to the inner wall of the opening, which places high demands on assembly and structural precision. When injection molding deformation or excessive assembly deviation occurs, it can easily lead to assembly failure. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes a display device housing assembly. The display device housing assembly is connected to a back panel. The display device housing assembly includes an AV bracket and a rear shell. The AV bracket includes a base and an access plate connected to the base. The base is connected to the back panel. The access plate has an access hole. A receiving cavity is formed inside the rear shell. The rear shell covers the back panel. An opening is provided on the side wall of the rear shell. The access plate is located inside the receiving cavity and covers the inner periphery of the opening to isolate the opening from the receiving cavity. Attached Figure Description

[0030] This utility model proposes a display device housing assembly 100.

[0031] Please see Figures 3 to 6 In one embodiment of the present invention, the display device housing assembly 100 includes an AV bracket 1 and a rear shell 2. The AV bracket 1 includes a base 11 and an access plate 12 connected to the base 11. The base 11 is connected to a back plate 3. The access plate 12 is provided with an access hole 12a. A receiving cavity 2a is formed inside the rear shell 2. The rear shell 2 covers the back plate 3. An opening 2b is provided on the side wall of the rear shell 2. The access plate 12 is located inside the receiving cavity 2a and covers the inner periphery of the opening 2b to isolate the opening 2b from the receiving cavity 2a.

[0032] In this embodiment, the AV bracket 1 includes a base 11 and an access plate 12 connected to the base 11. The base 11 is used to connect to the back plate 3 to fix the AV bracket 1. The base 11 can be directly connected and fixed to the back plate 3, or it can be connected to the core board on the back plate 3 and then fixed to the back plate 3 through the core board. The base 11 can adopt a plate-like structure that fits against the back plate 3. The base 11 can be detachably connected to the back plate 3 for installing the AV bracket 1, and can be flexibly replaced when the AV bracket 1 is damaged. The access plate 12 is connected to the base 11 and is used to install audio and video signal interfaces. Therefore, the access plate 12 is provided with access holes 12a for fixing audio and video signal interfaces. For example, the access hole 12a can be configured to be suitable for installing USB interfaces, HDMI interfaces, RCA interfaces, etc. Optionally, the access board 12 can be configured as a base 11 perpendicular to the plate shape. In this way, when the display device is installed on the wall or stands on the side of the wall by a bracket, after the audio and video connection cable is inserted into the access board 12 through the plug, the extension direction of the audio and video connection cable can be parallel to the screen, saving space. Therefore, the display device can fit more closely to the wall.

[0033] The rear shell 2 can adopt a dome-shaped structure and cover the back plate 3. A receiving cavity 2a is formed inside the rear shell 2. Electronic components such as PCBA boards are typically mounted on the back plate 3. The receiving cavity 2a is used to accommodate these electronic components. Therefore, the rear shell 2 covers the AV bracket 1 and the PCBA boards to provide physical protection and prevent damage to the PCBA boards and other electronic components on the back plate 3. An opening 2b is provided on the side wall of the rear shell 2. It should be noted that the side wall of the rear shell 2 refers to the wall connecting the rear shell 2 and the back plate 3. The access plate 12 is located within the receiving cavity 2a and covers the opening 2b. That is, the access plate 12 is located within the receiving cavity 2a and connected to the back plate 3. Simultaneously, the rear shell 2 is also connected to the back plate 3. The access plate 12 is positioned corresponding to and covers the opening 2b. The access plate 12 can be spliced ​​with the side of the inner peripheral wall of the opening 2b facing the receiving cavity 2a.

[0034] Please see Figures 1 to 2 In related technologies, when the AV bracket 1 is inserted into the opening 2b, the outer peripheral wall of the AV bracket 1 is limited by the inner peripheral wall of the opening 2b. This often prevents the assembly of the back shell 2 and the AV bracket 1 when injection molding deformation or assembly errors occur. It should be noted that in actual production, if normal assembly is achieved, such deformation and assembly errors will not affect the support function of the AV bracket 1 or its ability to connect audio / video cables to the display device. This embodiment, by placing the AV bracket 1 within the receiving cavity 2a, avoids the inner wall of the opening 2b limiting the AV bracket 1. Even when the AV bracket 1 or the back shell 2 experiences certain deformation or assembly errors, normal assembly can still be maintained.

[0035] Further, please refer to Figure 7 and Figure 11 The inner wall of the opening 2b near the back plate 3 has a notch 2c, and the base 11 extends into the notch 2c. The base 11 is located between the inner wall of the notch 2c and the back plate 3.

[0036] In related technologies, to enhance the strength of the connection between the AV bracket 1 and the rear shell 2 and the back plate 3, a planar connection structure 201 is provided on the rear shell 2 on the side of the opening 2b. Please refer to [link / reference]. Figure 1 and Figure 2The small planar structure forms one side of the inner wall of opening 2b. During injection molding, the planar connection structure 201 is relatively weak and prone to water inclusion patterns. Stress concentration at these water inclusion patterns can reduce structural strength and cause defects in the structural appearance. Furthermore, the planar connection structure 201 is easily deformed due to its weakness, resulting in large gaps and misalignments between it and the back plate 3 and AV bracket 1, affecting the product's sealing and appearance. Therefore, in this embodiment, a notch 2c is provided on the inner wall of opening 2b near the back plate 3 to eliminate the planar connection structure 201, preventing water inclusion patterns during injection molding of the back shell 2 and avoiding gaps and misalignments between the back shell 2 and the back plate 3 or AV bracket 1 due to deformation of the planar connection structure 201. The base 11 is inserted into the notch 2c to replace the original planar connection structure 201. This maintains the integrity of the back shell 2's structural appearance while strengthening the connection between the AV bracket 1 and the back plate 3, improving the stability of the AV bracket 1 installation. In addition, when using injection molding to produce the back shell 2, please refer to... Figures 12 to 13 ,from Figure 12 It can be seen that when the planar connection structure 201 is set, the injection filling time of the rear shell 2 is 1.821 seconds. Figure 13 As can be seen from this, the injection filling time of the rear shell 2 in this embodiment is 1.765 seconds, which means that the injection cycle of the rear shell 2 in this embodiment is significantly shorter than the injection cycle when the planar connection structure 201 is set, thus improving production efficiency.

[0037] It should be noted that the size of the notch 2c is slightly larger than the size of the opening 2b, that is, the projected area of ​​the notch 2c on the back plate 3 is slightly larger than the projected area of ​​the opening 2b on the back plate 3. The base 11 extends into the notch 2c. When the back shell 2, AV bracket 1 and back plate 3 are installed, the inner wall of the notch 2c presses the base 11 against the back plate 3, thereby limiting the base 11 between the inner wall of the notch 2c and the back plate 3, preventing the base 11 from moving along the direction from the back plate 3 to the back shell 2. This setting can improve the anti-collapse ability of the AV bracket 1. That is, when the user plugs or unplugs the audio and video signal plug, a force is applied to the access board 12 towards the inside or outside of the receiving cavity 2a. At this time, the access board 12 is prone to collapse and damage due to the force. Since the access plate 12 is connected to the base 11, the external force generated by insertion and removal will apply a torque to the base 11 around the junction line between the base 11 and the access plate 12. In this embodiment, by confining the base 11 between the inner wall of the notch 2c and the back plate 3, the torque generated by insertion and removal can be resisted, thereby improving the anti-collapse capability of the access plate 12. To strengthen the connection between the base 11 and the access plate 12, the access plate 12 and the base 11 can adopt an integral molding structure.

[0038] Further, please refer to Figure 6In one embodiment of the present invention, a first rib 122 is provided on the side of the access plate 12 facing the opening 2b. The first rib 122 extends along the direction close to the inner wall of the opening 2b and is spliced ​​with the inner wall of the opening 2b. The first rib 122 connects the access plate 12 and the base 11.

[0039] In this embodiment, considering that a torque will be generated between the access board 12 and the base 11 when the user plugs in or unplugs the audio / video signal plug, and that excessive torque may cause cracks or damage between the access board 12 and the base 11, a first rib 122 is provided on the side of the access board 12 facing the opening 2b, and the first rib 122 connects the access board 12 and the base 11. This strengthens the connection between the access board 12 and the base 11, improves the resistance to torque, and prevents cracking between the access board 12 and the base 11. Considering that the first rib 122 protrudes from the access plate 12, directly exposing it would be inconvenient for plugging and unplugging the audio / video signal connectors and would also affect the aesthetics of the display device. Therefore, the first rib 122 extends along the direction close to the inner wall of the opening 2b and is spliced ​​with the inner wall of the opening 2b. That is, the first rib 122 is aligned with the inner wall of the opening 2b before splicing. In this way, the first rib 122 can be coplanar with the inner wall of the opening 2b. The splicing seam between the first rib 122 and the inner wall of the opening 2b is located on the inner side of the opening 2b. When the user plugs and unplugs the audio / video signal connector, they usually look into the opening 2b from the direction facing the access plate 12. At this time, the splicing seam cannot be directly observed. Please compare. Figure 2 and Figure 6 This design visually conceals the seams between the panels, enhancing the aesthetics of the display device.

[0040] Further, please refer to Figure 6 In one embodiment of the present invention, the access plate 12 is provided with at least two first ribs 122, wherein the two first ribs 122 are respectively spliced ​​with the two opposite inner walls of the opening 2b.

[0041] In this embodiment, to maintain the seal between the AV bracket 1 and the rear shell 2, a first rib 122 is provided at both ends of the AV bracket 1, and the two first ribs 122 are respectively spliced ​​with the two opposite inner walls of the opening 2b. In this way, the two first ribs 122 achieve a seal between the AV bracket 1 and the two inner walls of the opening 2b adjacent to the back plate 3. It should be noted that the seal achieved by splicing here mainly serves to prevent dust and optimize the appearance. It can be understood that, in order to further strengthen the connection between the access plate 12 and the base 11, the number of first ribs 122 can be increased from two according to actual needs. Furthermore, in order to maintain the symmetry of the force on the AV bracket 1, two or more first ribs 122 can be set symmetrically about the center line of the AV bracket 1.

[0042] Further, please refer to Figures 7 to 8 In one embodiment of the present invention, an overlapping portion 24 is provided on an inner wall of the opening 2b away from the back plate 3. The overlapping portion 24 extends along the access plate 12 and overlaps with the side of the access plate 12 facing the opening 2b.

[0043] In this embodiment, the overlapping portion 24 is a plate-shaped structure arranged parallel to the access plate 12. The overlapping portion 24 and the rear shell 2 are integrally formed. The overlapping portion 24 is located at the end of the inner wall of the opening 2b near the receiving cavity 2a. The overlapping portion 24 extends along the access plate 12 and overlaps with the side of the access plate 12 facing the opening 2b. That is, the access plate 12 is covered on the inner periphery of the opening 2b through the overlapping portion 24. The overlapping portion 24 is used to cover the gap between the access plate 12 and the inner wall of the receiving cavity 2a. Dust and other debris entering the gap will make it difficult to clean. The overlapping portion 24 can prevent dust and other debris from entering the gap. In addition, the overlapping portion 24 covering the gap between the rear shell 2 and the access plate 12 also improves the aesthetics of the display device.

[0044] Further, please refer to Figures 7 to 10 In one embodiment of the present invention, a first snap-fit ​​member 121 is provided on the side of the access plate 12 facing away from the opening 2b, and a second snap-fit ​​member 23 is provided on the inner wall of the receiving cavity 2a. The first snap-fit ​​member 121 and the second snap-fit ​​member 23 are snapped together.

[0045] In related technologies, a latch 202 is typically provided on the side of the AV bracket 1 facing the opening 2b to achieve the latching between the AV bracket 1 and the rear shell 2. The problem with this arrangement is that the latch 202 is located outside the receiving cavity 2a and exposed to the air, making it susceptible to damage from external forces. Furthermore, dust easily enters the gap between the latch 202 and the AV bracket 1, making cleaning difficult. In addition, the exposed latch 202 also results in an unsightly appearance of the AV bracket 1. Therefore, in this embodiment, a first latching member 121 is provided on the side of the access plate 12 facing away from the opening 2b, and a second latching member 23 corresponding to and cooperating with the first latching member 121 is provided on the inner wall of the receiving cavity 2a. Thus, by using the first latching member 121 and the second latching member 23 hidden within the receiving cavity 2a, the access plate 12 of the AV bracket 1 is latched to the inner wall of the receiving cavity 2a, strengthening the connection between the AV bracket 1 and the rear shell 2, and improving the ability of the outer shell assembly to withstand external force damage by sharing the load. Furthermore, this concealed design reduces the risk of damage to the first connector 121 and the second connector 23, improving their durability. It also enhances the aesthetics of the AV bracket 1 and the rear shell 2.

[0046] The first snap-fit ​​component 121 can be a cantilever snap-fit ​​202. The fixed end of the cantilever snap-fit ​​202 is connected to the side of the access plate 12 facing away from the opening 2b. The free end of the cantilever snap-fit ​​202 has an undercut protrusion. The second snap-fit ​​component 23 is a snap-fit ​​groove adapted to the undercut protrusion. The snap-fit ​​groove is opened on the inner wall of the receiving cavity 2a. The undercut protrusion can extend into the snap-fit ​​groove and snap-fit ​​with the inner wall of the snap-fit ​​groove. It can be understood that the positions of the cantilever snap-fit ​​202 and the snap-fit ​​groove can be interchanged without affecting the snap-fit ​​performance. That is, the second snap-fit ​​component 23 can be a cantilever snap-fit ​​202, the free end of the cantilever snap-fit ​​202 has an undercut protrusion, and the first snap-fit ​​component 121 is a snap-fit ​​groove adapted to the undercut protrusion.

[0047] For further details, please refer to Figures 7 to 10 In one embodiment of the present invention, the first snap-fit ​​member 121 has a base plate 1211 connected to the access plate 12. The base plate 1211 has a first elastic claw 1212 and a second elastic claw 1213 protruding towards the rear shell 2. A limiting space 121a is formed between the first elastic claw 1212 and the second elastic claw 1213. The second snap-fit ​​member 23 has a cantilever latch 231. A snap-fit ​​protrusion 232 is formed on the cantilever latch 231. The cantilever latch 231 extends into the limiting space 121a, and the snap-fit ​​protrusion 232 snaps into the first elastic claw 1212 and the second elastic claw 1213 respectively.

[0048] Considering that the single cantilever buckle 202 and the snap-fit ​​groove are prone to damage due to excessive deformation of the cantilever during disassembly caused by improper operation, this embodiment proposes a new snap-fit ​​design. In this embodiment, the first snap-fit ​​member 121 has a base plate 1211 connected to the access plate 12. One end of the base plate 1211 is connected to the side wall of the access plate 12 facing away from the opening 2b. In order to improve the convenience of snap-fit ​​operation, the base plate 1211 can be set to be perpendicular to the access plate 12. A first elastic claw 1212 and a second elastic claw 1213 are protruding from the side wall of the base plate 1211 facing the rear shell 2. A limiting space 121a is formed between the first elastic claw 1212 and the second elastic claw 1213. The second latching member 23 has a cantilever latch 231. The fixed end of the cantilever latch 231 is connected to the inner wall of the receiving cavity 2a. A latching protrusion 232 is formed on the cantilever latch 231. The cantilever latch 231 can extend into the limiting space 121a so that the latching protrusion 232 latches with the first elastic claw 1212 and the second elastic claw 1213 respectively. Further, the base plate 1211 between the first elastic claw 1212 and the second elastic claw 1213 can be provided with a clearance hole for the latching protrusion 232 and the cantilever latch 231 to extend into. The first elastic claw 1212, the second elastic claw 1213, the base plate 1211, and the access plate 12 can be integrally molded, as can the cantilever latch 231, the snap-fit ​​protrusion 232, and the rear shell 2. The first elastic claw 1212, the second elastic claw 1213, the base plate 1211, the cantilever latch 231, and the snap-fit ​​protrusion 232 can be made of engineering plastics with good elasticity and wear resistance, such as ABS, PC, and PA. In this embodiment, during the assembly and disassembly of the first snap-fit ​​component 121 and the second snap-fit ​​component 23, the cantilever latch 231, the first elastic claw 1212, and the second elastic claw 1213 can all undergo a certain degree of elastic deformation, thus withstanding greater deformation caused by improper operation. Compared to a single cantilever buckle 202, this reduces the risk of breakage or damage to the first snap-fit ​​component 121 and the second snap-fit ​​component 23.

[0049] Furthermore, in one embodiment of the present invention, the base 11 is provided with a first connecting part, and the back plate 3 is provided with a second connecting part, and the first connecting part and the second connecting part are detachably connected.

[0050] In this embodiment, for ease of maintenance, the AV bracket 1 and the backplate 3 are designed as separate units, and the base 11 of the AV bracket 1 is detachably connected to the backplate 3. Thus, if the access board 12 of the AV bracket 1 is damaged due to reasons such as unplugging or plugging in audio / video connectors, the entire AV bracket 1 can be replaced without affecting the backplate 3. Furthermore, to improve the installation accuracy of the base 11 and the backplate 3, the base 11 in this embodiment is provided with a positioning element 111, and the backplate 3 is provided with a positioning hole 3b. The positioning element 111 is inserted into the positioning hole 3b. Before the first connecting part and the second connecting part are detachably connected, positioning can be achieved by inserting the positioning element 111 into the positioning hole 3b to improve the accuracy of the AV bracket 1's installation position.

[0051] Furthermore, please refer to Figure 8 In one embodiment of this utility model, the first connecting part is a first through hole 11a, the second connecting part is a second through hole 3a, and the display device housing assembly 100 also includes mounting screws, which pass through the first through hole 11a and the second through hole 3a in sequence and connect the base 11 and the back plate 3; or, the first connecting part is a snap protrusion, the second connecting part is a snap groove, and the snap protrusion can extend into the snap groove and engage with the inner wall of the snap groove.

[0052] In this embodiment, two connection methods are proposed to connect the base 11 and the back plate 3. One method involves providing a first through hole 11a on the base 11 and a corresponding second through hole 3a on the back plate 3. A mounting screw is then passed through the first through hole 11a and the second through hole 3a to connect the base 11 and the back plate 3. Specifically, an internal thread matching the mounting screw can be provided on the inner wall of the second mounting through hole, or a nut can be provided to cooperate with the mounting screw for fixation. Alternatively, the first through hole 11a and the second through hole 3a can be designed as strip holes to prevent assembly errors that could prevent the AV bracket 1 from being assembled with the back plate 3. This method offers the advantages of a strong connection and high resistance to external forces. The other method involves providing a protruding tab on the base 11 facing the back plate 3, with a barb on the protruding tab. A slot is provided on the back plate 3, with a rib on the side wall of the slot that engages with the barb. The barb and the rib engage to achieve a detachable connection between the base 11 and the back plate 3. This method offers the advantage of quick assembly and disassembly.

[0053] Further, please refer to Figure 10 In one embodiment of the present invention, the inner wall of the receiving cavity 2a is provided with at least two second ribs 21 that are spaced apart and extend along the periphery of the opening 2b, and the inner wall of the receiving cavity 2a is also provided with a third rib 22, which are sequentially connected to each of the second ribs 21.

[0054] Considering that the wall of the rear shell 2 around the opening 2b is relatively weak after the opening 2b is provided, and is easily damaged under external force, this embodiment provides at least two spaced second ribs 21 on the inner wall of the receiving cavity 2a. Each second rib 21 extends along the periphery of the opening 2b. In order to improve the connection between the multiple second ribs 21 so that the shell can evenly distribute the external force, this embodiment also provides multiple third ribs 22. Each third rib 22 is connected to multiple second ribs 21 in sequence. In this way, a grid-like rib is provided around the opening 2b, which strengthens the strength of the rear shell 2 around the opening 2b and improves the ability of the rear shell 2 to resist external damage.

[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
