Description

Technical Field

[0001] This utility model relates to the field of audio-visual machine technology, specifically to an audio-visual machine shaft device. Background Technology

[0002] With the development of the times, people's lives have been greatly improved. In order to meet people's increasing entertainment needs, all kinds of entertainment audio-visual equipment have appeared on the market, such as AV players.

[0003] Specifically, an audio-visual machine is a professional machine specifically designed for recording, recording, burning, and producing music and television programs. The existing structure of an audio-visual machine consists of internal components housed in a cabinet, which provides protection for the stored equipment, shields against electromagnetic interference, and allows for the orderly and neat arrangement of equipment for easy maintenance. During installation, the cabinet is fixedly installed at the bottom of desktops such as computer desks and conference tables.

[0004] In addition, an AV player is an intelligent control device that can connect to audio or video playback devices. It can select playback devices to operate according to the user's needs through remote control or control panel, thus realizing the intelligent upgrade of home theater.

[0005] The display screen of an AV receiver can usually be rotated, for example, by rotating it at a certain angle relative to the receiver's cabinet. This allows the display screen to be adjusted to a suitable viewing angle according to different occasions and environments, making it easier for users to see the content displayed on the screen clearly and intuitively.

[0006] Display screens are typically connected to the cabinet via a hinge. Existing hinge structures often suffer from various problems, such as inflexible rotation, noise, or short lifespan, frequently resulting in reduced hinge damping that prevents the display screen from being set at the required angle.

[0007] Therefore, it is practically necessary for the industry to provide an improved AV receiver hinge device to overcome the shortcomings of the prior art. Utility Model Content

[0008] The purpose of this invention is to solve the above-mentioned problems and provide a rotating shaft device for an audio-visual machine.

[0009] To achieve the objectives of this utility model, the following technical solution is adopted:

[0010] An audio-visual player hinge device includes: a housing, and a display screen rotatably mounted on the top of the housing via a hinge assembly; the hinge assembly includes a hinge and a mounting bracket rotatably connected to the hinge in a damped manner, the hinge has a set of first mounting holes for fixing the hinge to the back of the display screen, and the mounting bracket has a set of second mounting holes for fixing the mounting bracket to the top of the housing.

[0011] Preferably, the rotating shaft has a shaft rod, and the set of first mounting holes are formed on the shaft rod. Preferably, the shaft rod has a flat portion, and the set of first mounting holes are formed on the flat portion.

[0012] Furthermore, an end cap is formed at the end of the shaft away from the planar portion. Preferably, a reinforcing rib is formed at one end of the mounting bracket. Preferably, handles are provided on the left and right sides of the housing.

[0026] In one embodiment of the present invention, referring to Figures 1-3, an audio-visual player hinge device 100 is provided, including: a housing 10 and a display screen 20 rotatably disposed on the top of the housing 10 via a hinge assembly 30.

[0027] In the above embodiments, the AV receiver can be various types of devices, such as having various types of external interfaces, namely video source input or audio source input interfaces. For video source input interfaces, these can include traditional RCA connectors, coaxial cables, or component video inputs, or HDMI interfaces, etc., and this invention does not limit this. For audio source input interfaces, they can also include, for example, TRS connectors (large / small three-pin), RCA connectors, XLR connectors, etc.

[0028] Furthermore, in the above embodiments, the display screen 20 can be a display screen of various types and sizes, such as a CRT display screen, an LCD display screen, an LED display screen, or an OLED display screen, etc. Its size depends on the size of the entire audio-visual machine. The larger the size, the larger the volume it occupies, which brings inconvenience to the portability of the device. Therefore, a larger size is not necessarily better.

[0029] Here, for reference Figure 3 The rotating shaft assembly 30 includes a rotating shaft 32 and a mounting bracket 34 rotatably connected to the rotating shaft 32 with a certain damping. A set of first mounting holes 3222 are provided on the rotating shaft 32 for fixing the rotating shaft 32 to the back of the display screen 20. A set of second mounting holes 342 are provided on the mounting bracket 34 for fixing the mounting bracket 34 to the top of the housing 10.

[0030] In this embodiment, the hinge 32 is fixed to, for example, the top two sides of the housing 10, while the mounting bracket 34 is mounted on the back of the display screen 20, and there is a certain damping effect between the hinge 32 and the mounting bracket 34. Therefore, the display screen 20 can be unfolded relative to the housing 10 to any suitable angle, and the display screen 20 can be maintained at that suitable angle. Ultimately, this allows users to arbitrarily adjust the unfolding angle of the display screen 20 according to different locations and environments, making it very convenient to use. Furthermore, the entire hinge assembly 30 has a simple structure; it can be fixed to the back of the display screen and / or the top of the housing by screws passing through the corresponding mounting holes. Moreover, the damping cooperation between the hinge and the mounting bracket greatly extends the service life of the entire product, improves the user experience, and significantly saves users purchase costs.

[0031] In one embodiment, the rotating shaft 32 has a shaft 322, and a set of first mounting holes 3222 are formed on the shaft 322. The shaft 322 is a crucial main rotating component; therefore, it needs to be made of a material with sufficient rigidity and wear resistance, while also not being too heavy. Therefore, titanium alloy is preferably used to form the shaft 322 to meet these requirements.

[0032] Preferably, a flat portion 3224 is formed on the shaft 322, and a set of first mounting holes 3222 are formed on the flat portion 3224. By machining the flat portion on the shaft, the machining of the first mounting holes can be made easier and more precise, thereby improving the machining accuracy of the first mounting holes and making it easier for screws to pass through the first mounting holes to fix the shaft to the top of the housing.

[0033] More preferably, an end cap 324 is formed at the end of the shaft 322 away from the flat portion 3224, and the end cap 324 serves to limit the axial movement of the shaft 322. Specifically, during the rotation of the shaft 322, the shaft 322 is prone to detach from the mounting bracket 34 over time. After providing the end cap 324, the end cap 324 prevents the shaft 322 from detaching from the mounting bracket 34 axially, thereby making the use of the rotating shaft assembly more stable and reliable.

[0034] Preferably, to increase the structural rigidity and strength of the mounting bracket 34, the mounting bracket 34 can be modified. Specifically, a reinforcing rib 344 is formed at one end of the mounting bracket 34, which makes the mounting bracket 34 strong enough, smoother and more stable during use, and prevents deformation that would affect the unfolding and folding of the display screen.

[0035] Preferably, handles 40 are provided on the left and right sides of the box body 10, so as to facilitate the user to lift the entire product and ultimately realize the mobility of the product. The handles 40 can be made of any material, such as leather, so as to have a certain degree of softness, easy to hold, and not make the user feel tired.

[0036] Preferably, the top of the housing 10 forms a top wall 12, and a groove 122 is formed in the top wall 12, and the display screen 20 is housed in the groove 122.

[0037] More preferably, stepped portions 124 are formed on both sides of the left side of the groove 122, and the mounting bracket 34 is fixed on the stepped portions 124.

[0038] In addition, a speaker can be installed inside the housing 10 to enable sound playback from the entire device.

[0039] Those skilled in the art will understand that the steps, measures, and solutions in the various operations, methods, and processes discussed in this application can be alternated, modified, combined, or deleted. Furthermore, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted. Furthermore, steps, measures, and solutions in the prior art that are similar to those disclosed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted.

[0040] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
