Description

TECHNICAL FIELD

[0001] The utility model relates to audio equipment field, especially a shell structure of audio equipment. BACKGROUND

[0002] At present, the shell of most audio equipment is composed of a bottom shell and a cover, wherein the bottom shell is mostly a metal bottom shell with an open top. In the process of processing the metal bottom shell, the metal plate of appropriate size is first cut off; then notches are cut off on the four peripheral ends of the metal plate (the excess material is removed to facilitate the bending and splicing of the ends of the metal plate); then the ends of the metal plate are formed into a fence by bending upward; finally, the ends of the adjacent fences are welded and fixed together by welding; only in this way can the bottom shell with an open top be obtained. Since the metal plate to be cut off is irregular, and accurate measurement and calculation are required to ensure that the cut-off metal plate has high quality, the cutting of the metal plate is relatively cumbersome. When the production enterprise changes to produce bottom shells of other sizes, it needs to re-perform the cumbersome cutting work, which easily affects the efficiency of the production enterprise in upgrading the bottom shell. At the same time, cutting notches on the metal plate will cause a lot of material waste, especially when producing a bottom shell with a large depth. Therefore, it is necessary to solve the above technical problems. SUMMARY

[0003] The utility model aims at solving the above problems and deficiencies, and provides a shell structure of audio equipment, which not only facilitates the standardized and modularized production, but also facilitates the rapid acquisition of the required size of the shell when changing to produce shells of different sizes, which facilitates the improvement of the efficiency of the shell upgrading; and it also facilitates the reduction of material waste, even when manufacturing a shell with a large depth, it can also facilitate the reduction of material waste.

[0004] The technical scheme of the utility model is implemented as follows:

[0005] A shell structure of audio equipment, characterized in that it comprises a bottom plate and a plurality of positioning blocks, wherein the top of the bottom plate is provided with a mounting cavity position, each positioning block is arranged on the top of the bottom plate, and each positioning block is arranged around the mounting cavity position, and a closure plate is arranged between each two adjacent positioning blocks.

[0006] Preferably, a fitting groove is formed in the positioning block, and the end of the closure plate is fitted in the fitting groove.

[0007] Preferably, a lap joint notch is formed in the positioning block, and the end of the closure plate is fixedly lapped on the lap joint notch.

[0008] Preferably, at least two vertically extending C-shaped notches are formed in the positioning block.

[0009] Preferably, the positioning block comprises a transverse arm and a longitudinal arm, one end of the transverse arm and one end of the longitudinal arm are connected by a circular arc transition, and the transverse arm and the longitudinal arm are respectively connected with the corresponding closing plate.

[0010] Preferably, the positioning block is an aluminum profile structure.

[0011] Preferably, a plurality of heat dissipation convex strips are integrally formed on the outer wall of the positioning block.

[0012] Preferably, a groove is formed on the outer wall of the positioning block, and each heat dissipation convex strip is located in the groove.

[0013] Preferably, the bottom plate and the closing plate are both aluminum plates.

[0014] Preferably, a circuit board is arranged in the mounting cavity, and two ends of the circuit board are respectively connected with the corresponding closing plate.

[0015] The audio equipment has the following advantages: the bottom plate and a plurality of positioning blocks are arranged on the shell structure, the positioning blocks are arranged on the top of the bottom plate, the positioning blocks are arranged around the mounting cavity, and the closing plate is arranged between each two adjacent positioning blocks. The positioning blocks can facilitate standardized and modularized production, and then the bottom plate and the closing plate of different sizes are cut to quickly assemble the shell of different sizes. Since the bottom plate and the closing plate are both plate bodies and do not need to be bent, the cutting is very simple, so that the shell of the required size can be quickly obtained when the shell of different sizes is produced, thereby improving the efficiency of shell updating and upgrading. Since the bottom plate and the closing plate do not need to be cut to facilitate bending, material waste can be reduced, and material waste can be reduced even when manufacturing a shell with a large depth.

[0019] As Figure 1 With Figure 2As shown in the shell structure of the audio equipment, the bottom plate 1 and the plurality of positioning blocks 2 are adopted, and each positioning block 2 is arranged on the top of the bottom plate 1 and surrounds the mounting cavity position 10, and each adjacent two positioning blocks 2 are respectively provided with the closing plate 3. In this way, the positioning block 2 can facilitate the standardized and modular production, and then the bottom plate 1 and the closing plate 3 of different sizes are cut, so that the shell of different sizes can be quickly assembled. Since the bottom plate 1 and the closing plate 3 are both plate bodies, and no bending structure needs to be made on the bottom plate 1 and the closing plate 3, the cutting is very simple, so that when the shell of different sizes is produced, the shell of the required size can be quickly obtained, thereby the efficiency of updating and upgrading the shell can be improved. Since the bottom plate 1 and the closing plate 3 do not need to be cut to form a gap for bending, material waste can be reduced, and even when a shell of large depth is manufactured, material waste can be reduced.

[0020] As shown in the shell structure of the audio equipment, the bottom plate 1 and the plurality of positioning blocks 2 are adopted, and each positioning block 2 is arranged on the top of the bottom plate 1 and surrounds the mounting cavity position 10, and each adjacent two positioning blocks 2 are respectively provided with the closing plate 3. In this way, the positioning block 2 can facilitate the standardized and modular production, and then the bottom plate 1 and the closing plate 3 of different sizes are cut, so that the shell of different sizes can be quickly assembled. Since the bottom plate 1 and the closing plate 3 are both plate bodies, and no bending structure needs to be made on the bottom plate 1 and the closing plate 3, the cutting is very simple, so that when the shell of different sizes is produced, the shell of the required size can be quickly obtained, thereby the efficiency of updating and upgrading the shell can be improved. Since the bottom plate 1 and the closing plate 3 do not need to be cut to form a gap for bending, material waste can be reduced, and even when a shell of large depth is manufactured, material waste can be reduced.

[0021] The height of each positioning block 2 and each closing plate 3 is the same, the shell structure further comprises a panel (not shown in the figure), the panel covers the cavity opening of the mounting cavity position 10, and the panel is locked on the positioning block 2 by a screw (not shown in the figure), so that a complete shell structure can be assembled.

[0022] As Figure 1 With Figure 2 As shown, different sizes of closing plates 3 and bottom plates 1 can be used to assemble shell structures of different sizes, for example, when a rectangular shell is assembled using one bottom plate 1, four positioning blocks 2 and four closing plates 3, after adjusting the size of the bottom plate 1 and the closing plate 3, a rectangular shell of different size can be assembled.

[0023] As Figures 1 to 3 As shown, the positioning block 2 is provided with an embedding groove 21, and the end of the closing plate 3 is embedded in the embedding groove 21. In this way, the positioning of the closing plate 3 can be quickly and stably achieved, thereby the convenience and stability of the installation and positioning of the closing plate 3 can be improved.

[0024] As Figures 1 to 3 As shown, the positioning block 2 is provided with a lap joint gap 22, and the end of the closing plate 3 is fixedly lapped on the lap joint gap 22. This can facilitate the quick and accurate assembly of the closing plate 3 and the positioning block 2, thereby the efficiency and accuracy of the installation and positioning of the closing plate 3 can be improved.

[0025] As Figures 1 to 3As shown in the figure, the lap joint gap 22 is towards the outside of the mounting cavity site 10, the closure plate 3 is lap jointed into the lap joint gap 22 from the outside to the inside, and the closure plate 3 is locked on the positioning block 2 by the screw (not shown in the figure) after being lap jointed into the lap joint gap 22, so that the closure plate 3 can be conveniently fixed and lap jointed.

[0026] As shown in the figure, Figures 1 to 3 The positioning block 2 is provided with at least two vertically extending C-shaped gaps 23. The C-shaped gap 23 not only provides a reliable locking position for the screw, but also greatly reduces the probability of cracking of the positioning block 2 when the screw is locked. When it is necessary to fix the positioning block 2 on the bottom plate 1, the threaded end of the screw (not shown in the figure) is screwed on the C-shaped gap 23 after being passed through the bottom plate 1, so that the positioning block 2 can be stably mounted on the bottom plate 1.

[0027] The opening of the C-shaped gap 23 is towards the inside of the mounting cavity site 10, and the screw of the locking panel is also screwed on the C-shaped gap 23, which not only conveniently and stably realizes the mounting and positioning of the panel, but also avoids the threaded end of the screw from being exposed.

[0028] As shown in the figure, Figures 1 to 3 The positioning block 2 includes a transverse arm 24 and a longitudinal arm 25, one end of the transverse arm 24 is circularly arc transitionally connected with one end of the longitudinal arm 25, and the transverse arm 24 and the longitudinal arm 25 are respectively connected with the corresponding closure plate 3. Such positioning block 2 is very simple and reliable, which not only facilitates manufacturing, but also facilitates the connection of the closure plate 3 and reduces the risk of injury, thereby helping to further improve the applicability of the shell structure.

[0029] As shown in the figure, Figure 3 The embedding groove 21 and the lap joint gap 22 are respectively provided on the transverse arm 24 and the longitudinal arm 25, and at least one C-shaped gap 23 is respectively provided on the transverse arm 24 and the longitudinal arm 25. In this way, the positioning block 2 has a more stable and reliable structure, thereby helping to further improve the reliability and applicability of the shell structure.

[0030] As shown in the figure, Figure 3 The positioning block 2 is an aluminum profile structure. This not only enables the positioning block 2 to have high structural strength, but also facilitates improving the efficiency of batch manufacturing and achieving the heat dissipation requirement, thereby facilitating improving the reliability and use performance of the audio device.

[0031] As shown in the figure, Figure 3 The outer wall of the positioning block 2 is integrally formed with a plurality of heat dissipation protrusions 26. The heat dissipation protrusions 26 not only enhance the heat dissipation performance, but also facilitate ensuring that the positioning block 2 has high structural strength and play a role in anti-skid when the audio device is taken, thereby helping to further improve the applicability of the shell structure.

[0032] As Figure 3 shown, the outer wall of the positioning block 2 is formed with a groove 27, and each heat dissipation convex strip 26 is located in the groove 27. This can meet the heat dissipation and anti-skid effects, avoid the heat dissipation convex strip 26 being too prominent, and make the coordination of the shell structure better, thereby avoiding the adverse effects on the use of users.

[0033] The bottom plate 1 and the closing plate 3 are both aluminum plates. This not only can make the bottom plate 1 and the closing plate 3 have high structural strength, but also can facilitate the realization of the heat dissipation requirement, thereby facilitating the improvement of the reliability and use performance of the audio equipment.

[0034] As Figure 1 and Figure 2 shown, the mounting cavity 10 is arranged with a circuit board 4, and both ends of the circuit board 4 are respectively connected with the corresponding closing plate 3. This can facilitate the shell structure to have a compact structure, thereby facilitating the use in more environments, and further facilitating the improvement of the application range. And this can have better heat dissipation and heat conduction effects, which can facilitate the further improvement of the heat dissipation performance.

[0035] When the circuit board 4 is connected with the closing plate 3, the circuit board 4 can still be fixed on the bottom plate 1 through screws (not shown in the figure), which can ensure that the installation and positioning of the circuit board 4 still have high stability and reliability.

[0036] As Figure 1 and Figure 2 shown, when the circuit board 4 is connected with the closing plate 3, the circuit board 4 can be connected with the closing plate 3 through a socket assembly 41, and the socket assembly 41 is arranged through the closing plate 3, which can meet the assembly and use requirements.

[0037] In the actual manufacturing process, this shell structure can be used in audio signal converters, power amplifiers, set-top boxes, sound boxes, multimedia machines and other audio equipment, which can meet the actual use requirements.
