Description

Technical Field

[0001] The present invention relates to the technical field of control device structures, and particularly to an audio-visual multimedia centralized controller. Background Art

[0002] Audio-visual multimedia is a technology that stores and manages various information such as language, text, data, audio, and video through a computer, enabling users to communicate with the computer in real-time through multiple senses. In fact, the content displayed and carried by multimedia technology is all the product of computer technology.

[0003] When using audio-visual multimedia, it is inseparable from a centralized controller for information control and management. The centralized controller generally refers to a central controller, and its main function is to control peripheral devices through protocols. Generally, the control terminals are a digital signal control wireless touch screen, a digital signal control wired touch screen, a control panel, a computer software, and a remote control.

[0004] In the process of gradual development, the multimedia centralized controller has more and more functions and higher and higher heat dissipation requirements. However, due to the limited volume of the multimedia centralized controller, the heat dissipation structure adopted by it is mostly heat dissipation through ventilation holes or setting a fan blade rotation structure inside to enhance air flow. Essentially, it is to accelerate air circulation for heat dissipation. Relying solely on this structure for heat dissipation, it gradually cannot meet the increasing heat dissipation requirements. This application provides an audio-visual multimedia centralized controller to improve the heat dissipation efficiency. Summary of the Invention

[0005] Based on the above situation, the main purpose of the present invention is to provide an audio-visual multimedia centralized controller to solve the problem that relying solely on simple air flow cannot meet the increasingly high heat dissipation requirements of the audio-visual multimedia centralized controller.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] An audio-visual multimedia centralized controller, comprising a housing, a support assembly, and a heat dissipation assembly;

[0008] The housing includes a casing and a cover plate. The support assembly is disposed inside the casing. An accommodation cavity is provided inside the casing. A water tank is provided inside the cover plate. A slot is provided below the cover plate, and the slot is communicated with the water tank;

[0009] The heat dissipation assembly includes a mounting frame, a water-absorbing cloth, a connecting rod, an insertion strip, a water guiding wire, and a water guiding pad. The mounting frame is fixed to the connecting rod, the connecting rod is fixed to the insertion strip, the insertion strip can be inserted into the slot, a strip-shaped groove is provided above the insertion strip, and a wire groove is provided inside the connecting rod;

[0010] The water-absorbing cloth is fixed inside the mounting frame. The water-absorbing cloth abuts against the support assembly. The water guide pad is located in the strip-shaped groove, and the water guide wire is located in the wire groove. Both ends of the water guide wire are connected to the water guide pad and the water-absorbing cloth.

[0011] Preferably, the slot and the water tank are communicated through a fine hole. A water guide rod is fixed in the fine hole, and the water guide rod can contact the water guide pad.

[0012] Preferably, a riser pipe is fixed at the upper end of the water tank, and a pipe cap is threadedly connected to the riser pipe;

[0013] A side groove is formed on one side of the cover plate. The side groove is communicated with the water tank, and a plug is fixed in the side groove.

[0014] Preferably, the casing includes a front side, a rear side and two side sides;

[0015] The two side sides are arranged oppositely, and a plurality of heat dissipation grooves are formed on the two side sides.

[0016] Preferably, a diversion fan is fixed at a position inside the casing close to one of the side sides. The axial direction of the diversion fan is the same as the arrangement direction of the two side sides.

[0017] Preferably, a plurality of micro electric telescopic cylinders are fixed in the accommodation cavity. The telescopic rod of the micro electric telescopic rod is fixed to the mounting frame, and the connecting rod is a flexible rod.

[0018] Preferably, the support assembly includes two parallel rods and a vertical rod. The vertical rod is fixed between the two parallel rods, and the upper parallel rod can abut against the water guide cloth.

[0021] The beneficial effects of the present invention are as follows: During operation, heat-generating modules such as the circuit board and working modules of the multimedia audio and video centralized controller are fixed on the support components. The support components can be made of metal plates with high thermal conductivity, enabling heat to be transferred to the support components. When the cover plate is installed on the casing, the water tank, strip-shaped groove, and wire groove are all interconnected, allowing the water in the water tank to flow onto the water absorption pad. In cooperation with the water guide pad, the water in the water tank can be gradually adsorbed into the water guide pad. The water in the water guide pad moves to the water absorption cloth through the water guide wire, causing the water absorption cloth to be in a high humidity state. At this time, the wet water guide cloth comes into contact with the heat-bearing support component, and the support component can gradually evaporate the water guide cloth. During the evaporation process, it can absorb the heat of the support component, reducing the heat of the support component, improving the thermal conductivity of the support component, and further enhancing the heat dissipation effect of the heat-generating modules of the multimedia audio and video centralized controller. By providing a heat dissipation component, the multimedia audio and video centralized controller of the present application can change the traditional heat dissipation structure that solely relies on fans and air flow with a relatively simple structure and low cost, effectively improving the heat dissipation efficiency.

[0022] Other beneficial effects of the present invention will be elaborated in the specific implementation manner through the introduction of specific technical features and technical solutions.

[0034] Referring to Figures 1-5 , the present invention provides an audio-visual multimedia centralized controller, including a housing 1, a support assembly 2 and a heat dissipation assembly 3. The heat dissipation assembly 3 and the support frame are both fixed inside the housing 1. The support assembly 2 is used to install and support the circuit board and working modules in the centralized controller, playing a role in protection and heat conduction. The heat dissipation assembly 3 is used to quickly dissipate heat and improve the heat dissipation effect of the multimedia centralized controller.

[0035] The housing 1 includes a chassis 11 and a cover plate 12. The chassis 11 includes a front side 111, a back side 112, and two side sides 113. The two side sides 113 are arranged oppositely, the front side 111 and the back side 112 are arranged oppositely, and the side sides 113 are adjacent to and perpendicular to the front side 111 and the back side 112, making the chassis 11 a cuboid-shaped chassis 11 on the outside. It should be noted that the angle between the side side 113 and the front side 111 is not unique, that is, the shape of the chassis 11 is not restricted and can be changed according to the required appearance of the chassis 11.

[0036] A plurality of heat dissipation grooves 14 are provided on the surfaces of both side sides 113. The plurality of heat dissipation grooves 14 are arranged in a first direction. The heat dissipation grooves 14 are vertically arranged rectangular grooves, and the heat dissipation grooves 14 can cooperate with the heat dissipation component 3 to assist the multimedia central controller in quickly dissipating heat.

[0037] The arrangement direction of the front side 111 and the back side 112 is the first direction a. An accommodation cavity 13 is provided inside the chassis 11. The accommodation cavity 13 extends to one side of the chassis 11, making the back side 112 of the chassis 11 open. The cover plate 12 can be fixed on the chassis 11 to close the accommodation cavity 13. Specifically, a plurality of upright columns 131 are fixed inside the accommodation cavity 13. The axial direction of the upright columns 131 is the first direction a. A threaded hole 132 is provided at the end of the upright column 131 close to the back side 112. A plurality of stepped grooves 121 are provided on the surface of the cover plate 12. The stepped grooves 121 can be aligned with the threaded holes 132, and bolts can be driven into the stepped holes to fix the cover plate 12 on the back side 112 to close the accommodation cavity 13.

[0038] A water tank 122 is provided inside the cover plate 12. A riser pipe 123 is fixed at the upper end of the water tank 122. The riser pipe 123 is communicated with the water tank 122. A pipe cap 124 is threadedly connected to the riser pipe 123. Water can be added to the water tank 122 through the riser pipe 123, and the pipe cap 124 can prevent the water in the water tank 122 from leaking and evaporating. Further, a lateral groove 125 is provided on one side of the cover plate 12. The lateral groove 125 is communicated with the water tank 122. A plug 126 that can close the lateral groove 125 is fixed inside the lateral groove 125. The plug 126 can be threadedly connected to the lateral groove 125. The water in the water tank 122 can be quickly discharged through the lateral groove 125, so as to adapt to various working forms. When the working efficiency of the controller is low, the water in the water tank 122 can be emptied, causing the heat dissipation component 3 to stop working.

[0039] When the cover plate 12 is fixed to the chassis 11, a slot 127 is provided on the side of the cover plate 12 close to the accommodation cavity 13. The slot 127 can be communicated with the inside of the water tank 122 through a plurality of fine holes 128. The diameter of the fine holes 128 is less than 1 mm. A water guide rod 129 is inserted and fixed in the fine holes 128. The water guide rod 129 is a soft rod with water absorption ability. The water guide rod 129 and the slot 127 can cooperate with the heat dissipation component 3 to improve the heat dissipation ability inside the chassis 11.

[0040] The heat dissipation component 3 includes a mounting frame 31, a water-absorbing cloth 32, a connecting rod 33, an insertion strip 34, a water guide wire 35, and a water guide pad 36. The mounting frame 31 is fixed inside the housing 11, and the mounting block is located above the support component 2. The water-absorbing cloth 32 is fixed to the upper side of the mounting frame 31, and the water-absorbing cloth 32 can contact the support component 2. A plurality of connecting rods 33 are provided, and the plurality of connecting rods 33 are fixed to one side of the mounting frame 31. The insertion strip 34 is fixed to the end of the connecting rod 33 away from the mounting frame 31. When the cover plate 12 is fixed to the housing 11, the insertion strip 34 can abut against the slot 127.

[0041] A strip-shaped groove 341 is formed above the insertion strip 34, and the water guide pad 36 is fixed inside the strip-shaped groove 341. The upper side of the water guide pad 36 is flush with the upper side of the strip-shaped groove 341. When the insertion strip 34 is inserted into the slot 127, the water guide pad 36 can contact the water guide rod 129. A wire routing groove 331 is formed in the connecting rod 33, and the water guide wire 35 is located in the wire routing groove 331. The two ends of the water guide wire 35 are respectively connected to the water guide pad 36 and the water-absorbing cloth 32, so that the water in the water tank 122 can be sequentially transferred to the water-absorbing cloth 32 through the water guide rod 129, the water guide pad 36, and the water guide wire 35.

[0042] When the device provided by the present application is working, heat-generating modules such as the circuit board and the working module of the multimedia audio and video centralized controller are all fixed on the support component 2. The support component 2 can be made of a metal material plate with a high thermal conductivity, so that heat can be transferred to the support component 2. When the cover plate 12 is installed on the housing 11, the water tank 122, the strip-shaped groove 341, and the wire routing groove 331 are all communicated, so that the water in the water tank 122 has the ability to flow to the water-absorbing pad. Cooperating with the water guide pad 36, the water in the water tank 122 can be gradually adsorbed into the water guide pad 36. The water in the water guide pad 36 moves to the water-absorbing cloth 32 through the water guide wire 35, resulting in the water-absorbing cloth 32 being in a high humidity state. At this time, the wet water guide cloth contacts the heat-generating support component 2, and the support component 2 can gradually evaporate the water guide cloth. During the evaporation process, the heat of the support component 2 can be absorbed, so that the heat of the support component 2 is reduced, the thermal conductivity of the support component 2 can be improved, and further the heat dissipation effect of the heat-generating module of the multimedia audio and video centralized controller can be improved. The multimedia audio and video centralized controller provided by the present application has a simple structure and low manufacturing cost by setting the heat dissipation component 3, changes the traditional single heat dissipation structure using only a fan and air flow, and can effectively improve the heat dissipation efficiency.

[0043] As an embodiment, a diversion fan 114 is fixedly installed inside the chassis 11 near the side 113. The axis direction of the diversion fan 114 is the same as the arrangement direction of the two sides 113. When the fan works, it can drive air to flow from one side 113 to the other side 113, enabling the air to quickly pass through the water guide cloth. On the one hand, it can improve the evaporation efficiency of the water guide cloth and further enhance the heat dissipation efficiency; on the other hand, it can also quickly blow the water vapor on the water guide cloth to the outside of the chassis 11, preventing excessive humidity inside the audio and video centralized controller and affecting normal operation.

[0044] As an embodiment, a plurality of micro electric telescopic cylinders 115 are arranged in the accommodation cavity 13. The telescopic rods of the micro electric telescopic cylinders 115 are arranged upward and fixedly connected to the storage and installation frame 31. The connecting rod 33 is a flexible rod and can deform with the swing of the installation frame 31. When the micro electric telescopic cylinder 115 works, it can push the installation frame 31 to move up and down. When the centralized controller works at low power, it can drain the water in the water tank 122 and move the water guide cloth upward to disengage from the support assembly 2, preventing the water guide cloth from dry burning.

[0045] As an embodiment, the support assembly 2 includes two parallel rods 21 and a vertical rod 22. The vertical rod 22 is fixed between the two parallel rods 21. The vertical rod 22 and the two parallel rods 21 are perpendicular to each other. The two parallel rods 21 and the vertical rod 22 enclose an area for fixing the working module of the audio and video multimedia centralized controller. The parallel rods 21 and the vertical rod 22 can be aluminum alloy rods. The water guide cloth abuts against the upper parallel rod 21, so that the heat of the aluminum alloy rod can be quickly absorbed. The support assembly 2 formed by enclosing with aluminum alloy rods has a simple structure, sufficient strength to protect the internal structure, and can also achieve a good heat conduction effect.

[0046] The implementation principle of the present invention is as follows: During operation, heat-generating modules such as the circuit board and working modules of the multimedia audio and video centralized controller are fixed on the support component 2. The support component 2 can be made of a metal material plate with a high thermal conductivity, enabling heat to be transferred to the support component 2. When the cover plate 12 is installed on the housing 11, the water tank 122, the strip-shaped groove 341, and the wire groove 331 are all interconnected, allowing the water in the water tank 122 to flow onto the water absorption pad. In cooperation with the water guide pad 36, the water in the water tank 122 can be gradually adsorbed into the water guide pad 36. The water in the water guide pad 36 moves to the water absorption cloth 32 through the water guide line 35, causing the water absorption cloth 32 to be in a high humidity state. At this time, the wet water guide cloth contacts the heat-generating support component 2, and the support component 2 can gradually evaporate the water guide cloth. During the evaporation process, the heat of the support component 2 can be absorbed, reducing the heat of the support component 2, improving the heat conduction ability of the support component 2, and further enhancing the heat dissipation effect of the heat-generating module of the multimedia audio and video centralized controller. The multimedia audio and video centralized controller provided in this application has a simple structure and low manufacturing cost by setting the heat dissipation component 3, changing the traditional heat dissipation structure that solely uses a fan and air flow, and can effectively improve the heat dissipation efficiency.
