Description

Technical Field

[0001] The utility model relates to the technical field of sound box equipment, in particular to a screen rotation structure and a sound box with a screen. Background Art

[0002] See also Figure 1 The speaker with screen includes a speaker body 3, a rotating mechanism 1, and a screen assembly 2 rotatably connected to the speaker body 3 through the rotating mechanism 1. The screen assembly 2 includes a screen bracket 201 whose lower end is connected to the rotating mechanism 1 and a screen body 202 fixed on the screen bracket 201.

[0003] When the user adjusts the tilt angle of the screen assembly 2, he usually holds the top of the screen assembly 2 and applies force backwards. Figure 2 As shown, the screen bracket 201 forms a lever with the rotating axis of the rotating mechanism 1 as the fulcrum, and bends and deforms backward. The bent and deformed screen bracket 201 drives the rotating mechanism 1 to push forward, and then abuts against the screen body 202, causing the screen body 202 to bend and deform as well, ultimately causing the displayed image to become abnormal.

[0004] Therefore, it is necessary to improve the existing speakers with screens to solve the problem that the rotating mechanism easily abuts against the screen body, causing abnormal display images.

[0005] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0035] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0037] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0038] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0039] The utility model provides a screen rotation structure and a speaker with a screen, which is suitable for application scenarios such as music playing or karaoke, and can effectively solve the problem that the rotation mechanism easily abuts against the screen body, causing abnormal display images.

[0040] The speaker with screen provided in this embodiment includes a speaker body and a screen rotation structure. Figure 3 and Figure 4 The screen rotation structure includes a rotation mechanism 1 and a screen assembly 2 that is rotationally connected to the sound box body through the rotation mechanism 1. The screen assembly 2 includes a screen bracket 201 connected to the rotation mechanism 1 and a screen body 202 mounted and fixed on the screen bracket 201. Specifically, the rotation mechanism 1 is connected to a side of the screen bracket 201 close to the screen body 202, and a spacing space 203 is provided between the rotation mechanism 1 and the screen body 202.

[0041] The screen rotation structure and the speaker with screen provided in the present embodiment, when force is applied to the screen assembly 2 to rotate the screen assembly 2 backward, although the screen bracket 201 will still bulge and deform toward the screen body 202, a spacing space 203 is provided between the rotating mechanism 1 and the screen body 202. The spacing space 203 provides a certain buffer space for the rotating mechanism 1, so that although the rotating mechanism 1 is closer to the screen body 202, it still cannot directly contact the screen body 202, that is, the rotating mechanism 1 will not abut against the screen body 202.

[0042] Therefore, the screen rotation structure and the speaker with screen provided by the present invention can effectively solve the problem that the rotating mechanism 1 easily abuts against the screen body 202, causing abnormal display images.

[0043] Optionally, the size of the spacing space 203 is 1.5 mm to 3 mm. Furthermore, the size of the spacing space 203 is 2 mm. When the size of the spacing space 203 is too large, the screen assembly 2 will appear very thick and bulky, and when the size of the spacing space 203 is too small, the rotating mechanism 1 is likely to contact the screen body 202. After summarizing many experiments, it was found that when the size of the spacing space 203 is 1.5 mm to 3 mm, especially when the size of the spacing space 203 is 2 mm, the rotating mechanism 1 is not likely to contact the screen body 202, and the overall thickness of the screen assembly 2 is relatively small.

[0044] See also Figure 5 In this embodiment, the rotating mechanism 1 includes a connecting piece 101 fixedly mounted on the screen bracket 201 and a rotating component 102 connected to the connecting piece 101 .

[0045] The rotating assembly 102 includes two coaxial and spaced transverse rotating shafts 1021, an inverted U-shaped frame 1022 rotatably connected to the two transverse rotating shafts 1021, and a longitudinal rotating shaft 1023 rotatably connected to the inverted U-shaped frame 1022; wherein the longitudinal rotating shaft 1023 is connected to the connecting piece 101. Specifically, the transverse rotating shaft 1021 is installed and fixed on the sound box body, so the screen assembly 2 can rotate forward and backward around the transverse rotating shaft 1021 relative to the sound box body, and rotate left and right around the longitudinal rotating shaft 1023 relative to the sound box body.

[0046] It is understandable that the size of the longitudinal shaft 1023 itself is relatively small. If the longitudinal shaft 1023 is directly fixed to the screen bracket 201, the area of ​​the connection surface between the two is limited and the reliability is not high. In this embodiment, a larger connecting piece 101 is connected between the longitudinal shaft 1023 and the screen bracket 201 as a transfer component, which can greatly increase the contact area between the rotating mechanism 1 and the screen bracket 201. Furthermore, the larger connecting piece 101 can not only provide more bolt holes, but also the distance between the bolt holes is larger, which is conducive to the rotating mechanism 1 being fastened to the screen bracket 201 at more positions. Moreover, when the rotating mechanism 1 is fastened to the screen bracket 201 at more positions, the structural strength of the screen bracket 201 will be further strengthened, the deformation amplitude of the screen bracket 201 protruding toward the screen assembly 2 will be reduced, and the rotating mechanism 1 will be further prevented from abutting against the back of the screen assembly 2.

[0047] See also Figure 6 The rotating assembly 102 also includes a first transverse anti-wear elastic member 1024, a second transverse anti-wear elastic member 1025, and a transverse nut 1026. A transverse shaft hole 1022a is provided at the end of the inverted U-shaped frame 1022; the transverse rotating shaft 1021 passes through the first transverse anti-wear elastic member 1024, the transverse shaft hole 1022a, and the second transverse anti-wear elastic member 1025 in sequence, and is threadedly connected with the transverse nut 1026.

[0048] The rotating assembly 102 further includes a first longitudinal anti-wear elastic member 1027, a second longitudinal anti-wear elastic member 1028, and a longitudinal nut 1029. A longitudinal shaft hole 1022b is provided in the middle of the inverted U-shaped frame 1022;

[0049] The longitudinal rotating shaft 1023 passes through the first longitudinal anti-wear elastic member 1027 , the longitudinal shaft hole 1022 b , and the second longitudinal anti-wear elastic member 1028 in sequence, and is then threadedly connected to the longitudinal nut 1029 .

[0050] Optionally, each of the anti-wear elastic parts is a gasket.

[0051] The connecting piece 101 includes two extensions 1011 symmetrically arranged about the axis of the longitudinal rotation axis 1023 and an intermediate connection portion 1012 connecting the two extensions 1011. The two transverse rotation axes 1021 are symmetrically designed about the longitudinal rotation axis 1023 to achieve uniform rotation force and small gap tolerance.

[0052] In this embodiment, the connecting piece 101 and the connecting piece 101 are detachably connected or welded. Connecting pieces 101 of different areas can be selected according to the area of ​​the screen bracket 201, and then the connecting piece 101 is welded or fastened to the rotating assembly 102 using bolts.

[0053] Specifically, by selecting an extension portion 1011 with a larger area, the contact area between the connecting piece 101 and the screen bracket 201 can be increased, thereby reducing the convex deformation amplitude of the screen bracket 201 toward the screen assembly 2.

[0054] Optionally, an oil storage gap 1022c for storing lubricating oil is provided between the transverse rotating shaft 1021 and the transverse shaft hole 1022a, and / or between the longitudinal rotating shaft 1023 and the longitudinal shaft hole 1022b. Lubricating oil is stored in the oil storage gap 1022c to improve the smoothness of rotation.

[0055] The screen rotation structure and the speaker with screen provided in this embodiment have the following advantages:

[0056] ① A spacing space 203 is provided between the rotating mechanism 1 and the screen body 202, which provides a certain buffer space for the rotating mechanism 1, so that the rotating mechanism 1 cannot abut against the screen body 202, thereby solving the problem that the rotating mechanism 1 easily abuts against the screen body 202 and causes abnormal display images;

[0057] ② The connecting piece 101 and the rotating component 102 are designed to be split, and a suitable connecting piece 101 can be selected according to the size and shape of the screen bracket 201, thereby improving the connection reliability and reducing the deformation of the screen bracket 201;

[0058] ③ The rotating assembly 102 is a symmetrical structure, the overall force is uniform, the matching tolerance gap is small, the rotation virtual position is small, and the rotation feel is good;

[0059] ④ Lubricating oil is stored in the oil storage gap 1022c to improve the smoothness of rotation.

[0060] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0061] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
