Description

Technical Field

[0001] The present application relates to the field of television displays, and in particular, to a synchronous drive pulley set and a television device having the same. Background Art

[0002] The appearance of traditional TV products mainly features static textures. Specifically, in the past, in terms of the appearance design of TV products, various static texture patterns were mainly used on parts such as the screen frame and the back panel to attract consumers, such as brushed textures and matte textures, which were used as an important feature and competitive point of the product appearance. In recent years, wallpaper TVs have received market attention due to their thinness and the ability to be mounted on the wall, and there are also more and more split-box TVs related to them. This type of TV places the main circuits, power supplies and other components in an independent split box, making the TV screen thinner and the installation more flexible, meeting the consumers' demands for home aesthetics and TV thinness.

[0003] The appearance layout of the electric rotation type requires more flexibility and space in the TV structure design to accommodate the rotation mechanism, etc. The split-box form provides convenience for this. Some components that may originally conflict with the rotation mechanism can be placed in the split box, allowing the screen part to focus on the realization of the rotation function. The combination of the two helps to improve the overall function and user experience of the TV. Moreover, the appearance layout of the electric rotation type TV is a new design method. The TV screen can be rotated through an electric device. This design not only makes the TV look more technological, meeting the consumers' pursuit of high-tech products, but also brings more fun to users, increasing the interest and interactivity of the product.

[0004] In the technology of realizing the electric rotation of the TV screen, the traditional link transmission mechanism has limitations. It has specific requirements for the size of the rotating wheels, which restricts the designers' play in the appearance design, making it difficult to achieve diverse and personalized appearance designs and unable to meet the market's demand for TV appearance differentiation. That is, for the traditional link transmission mechanism to achieve synchronous rotation of two rotating wheels, either the sizes of the two rotating wheels are the same, or the existing transmission mechanism is relatively complex.

[0005] Based on this, in addition to having requirements for the size of the rotating wheels, the traditional link transmission mechanism itself has a relatively complex internal structure and will occupy more internal space of the TV. This brings difficulties to the layout of other important components inside the TV, such as speakers and circuit boards, and affects the overall design and performance optimization of the TV.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will describe the technical solutions in the embodiments of this application clearly and completely with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or change in motion state, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" another element or feature will then be oriented as "above" or "on top of" another element or feature. Therefore, the example term "below" can include both the upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatially relative relationship descriptions used in the text have been interpreted accordingly.

[0042] With the technological transformation of television devices, the split-box form of television has gradually emerged, which provides convenience for the appearance layout of electric rotating televisions. Components that conflict with the rotating mechanism can be placed in the split box, enabling the screen to focus on the rotating function and enhancing the overall function and user experience. Exemplarily, the screen of an electric rotating television is rotated by an electric device, which is more technological in appearance, can bring more usage fun to users, and increase the interest and interactivity of the product. However, the existing electric devices for realizing rotation generally adopt traditional link transmission mechanisms. Moreover, the traditional link transmission mechanism has specific requirements for the size of the rotating wheel, which limits the creativity of designers, makes it difficult to achieve diversified and personalized appearance designs, and cannot meet the market's demand for television appearance differentiation. Further, the internal structure of the traditional link transmission mechanism is complex, occupying a relatively large amount of internal space of the television, bringing difficulties to the layout of other important components such as speakers and circuit boards, and affecting the overall design and performance optimization of the television.

[0043] To alleviate the above problems, the present invention provides a synchronous drive wheel set, which can adopt two rotating wheels of the same size or two rotating wheels of different sizes. A connecting rod is connected to the outer sides of the two rotating wheels, and a drive assembly is connected to the inner sides of the two rotating wheels. Herein, the inner side and the outer side can be two opposite surface regions of the mounting plate. In this way, the drive assembly located on the inner side of the mounting plate can make the two rotating wheels rotate synchronously. In the region on the outer side of the mounting plate, the following scene is mainly presented to the user: the two rotating wheels are rotating, and the connecting rod is swinging in a plane following the two rotating wheels. At the same time, based on the rotatable connection relationship between the connecting rod and each of the rotating wheels through the first cap assembly and the second cap assembly respectively, it can be understood by the user that the connecting rod realizes the synchronous rotation between two rotating wheels of the same size or two rotating wheels of different sizes. That is, the electric rotating function of the split-box form television can be realized through a simple structure.

[0044] The following refers to Figures 1-8 , and further elaborates on the synchronous drive wheel set of the present invention and the television device having the same.

[0045] The synchronous drive wheel set 1 provided in the embodiment of the present application includes: a mounting plate 11, a first rotating wheel 12, a second rotating wheel 13, a connecting rod 141, a first cap assembly 143, a second cap assembly 142, and a drive assembly 15. The first rotating wheel 12 and the second rotating wheel 13 are installed on the inner side of the mounting plate 11 in isolation from each other, and at least part of the first rotating wheel 12 and the second rotating wheel 13 protrudes out of the mounting plate 11 on the outer side.

[0046] Regarding the structural display on the inner side of the mounting plate 11: The drive assembly 15 is installed on the inner side of the mounting plate 11 and is synchronously drivingly connected to the first rotating wheel 12 and the second rotating wheel 13 respectively.

[0047] Regarding the structure on the outside of the mounting plate 11: one end of the connecting rod 141 is slidably connected to the first cap assembly 143 along its own axial direction, the first cap assembly 143 wraps at least part of the outer wall surface of the connecting rod 141, and is rotatably connected to the outer side of the first rotating wheel 12; the other end of the connecting rod 141 is connected to the second cap assembly 142, the second cap assembly 142 wraps at least part of the outer wall surface of the connecting rod 141, and is rotatably connected to the outer side of the second rotating wheel 13.

[0048] In this way, when the second rotating wheel 13 actively rotates, the first rotating wheel 12 rotates synchronously with the second rotating wheel 13, the second cap assembly 142 and the other end of the connecting rod 141 rotate synchronously with the second rotating wheel 13, and the first cap assembly 143 rotates synchronously with the first rotating wheel 12. During this process, the first cap assembly 143 can reciprocate along its own axial direction along the connecting rod 141.

[0049] Exemplarily, the mounting plate 11 includes a first side 111 and a second side 112 opposite to the first side 111, wherein the first side 111 is the outer side of the mounting plate 11, and the second side 112 is the inner side of the mounting plate 11; a first hole A and a second hole B isolated from each other are provided between the first side 111 and the second side 112; the first rotating wheel 12 is mounted on the first hole A, and the first rotating wheel 12 includes a first end 121 and a second end 122, the first end 121 is exposed on the first side 111, and the second end 122 is exposed on the second side 112; the second rotating wheel 13 is mounted on the second hole B, and the second rotating wheel 13 includes a third end 131 and a fourth end 132, the third end 131 is exposed on the first side 111, and the fourth end 132 is exposed on the second side 112.

[0050] In the connection assembly 14 consisting of the connection rod 141, the second cap assembly 142 and the first cap assembly 143, the connection rod 141 includes a fifth end 1411 and a sixth end 1412 away from the fifth end 1411 along its own axial direction, and the second cap assembly 142 is covered on the fifth end 1411, that is, the second cap assembly 142 at least partially wraps around the fifth end 1411 of the connection rod 141, and connects the fifth end 1411 to the second annular track 1311 of the third end 131 of the second rotating wheel 13. Exemplarily, the second The annular track 1311 can be a decorative piece; the first cap assembly 143 is connected to the first annular track 1211 of the first end 121 of the first rotating wheel 12. By way of example, the first annular track 1211 can also be a decorative piece; the sixth end 1412 passes through the side of the first cap assembly 143 along its own axial direction, and the connecting rod 141 is slidably matched with the first cap assembly 143; the driving assembly 15 is installed on the second side 112 of the mounting plate 11, and the driving assembly 15 is transmission-connected between the first rotating wheel 12 and the second rotating wheel 13.

[0051] In this way, when the second rotating wheel 13 rotates, the first rotating wheel 12 is configured to rotate synchronously with the second rotating wheel 13. The second cap assembly 142 and the fifth end 1411 of the connecting rod 141 rotate synchronously with the second annular track 1311 of the third end 131, and the first cap assembly 143 rotates synchronously with the first annular track 1211 of the first end 121. During this process, the first cap assembly 143 can reciprocate axially along the connecting rod 141.

[0052] Considering the specific solution for the synchronous transmission between the first rotating wheel 12 and the second rotating wheel 13 by the driving assembly 15, in the synchronous transmission pulley set 1 provided in this application, the driving assembly 15 includes a driving motor 151, a first-stage transmission assembly 152, and a second-stage transmission assembly 153. The first-stage transmission assembly 152 is drivingly connected between the second rotating wheel 13 and the driving motor 151, and the second-stage transmission assembly 153 is drivingly connected between the second rotating wheel 13 and the first rotating wheel 12 to make the first rotating wheel 12 and the second rotating wheel 13 rotate synchronously.

[0053] Combined with the setting of the specific ends of the foregoing first rotating wheel 12 and second rotating wheel 13, in the embodiment of this application, the first-stage transmission assembly 152 can be drivingly connected between the fourth end 132 of the second rotating wheel 13 and the driving motor 151, and the second-stage transmission assembly 153 can be drivingly connected between the fourth end 132 of the second rotating wheel 13 and the second end 122 of the first rotating wheel 12 to make the first rotating wheel 12 and the second rotating wheel 13 rotate synchronously.

[0054] Exemplarily, the driving connection here can be a synchronous belt pulley drive or a synchronous gear meshing drive.

[0055] When using a synchronous gear meshing drive, in the synchronous transmission pulley set 1 of this application, the first-stage transmission assembly 152 can include a worm 1521 and a turbine 1522. One end of the worm 1521 is in meshing transmission with the turbine 1522, and the other end of the worm 1521 is drivingly connected to the output end of the driving motor 151. In this way, the rotational speed of the output end of the driving motor 151 can be output with a large transmission ratio, and the structure of the turbine 1522 and the worm 1521 is relatively compact, with high transmission smoothness and high load-bearing capacity. It can also achieve spatial intersecting-axis transmission. Further, when the lead angle of the worm 1521 is less than the equivalent friction angle between teeth, the worm 1521 transmission has self-locking property, and only the worm 1521 can drive the turbine 1522, and the turbine 1522 cannot drive the worm 1521.

[0056] Considering the demonstration of the synchronous drive pulley set 1 provided in the embodiments of the present application, which can be applicable to the synchronous drive of two rotating wheels with different sizes outside the mounting plate 11. In the synchronous drive pulley set 1 provided in the embodiments of the present application, the radial dimension of the first rotating wheel 12 is larger than that of the second rotating wheel 13.

[0057] In this way, by applying a transmission component with a deceleration function, it is possible to achieve the synchronous drive demonstration of the larger-sized first rotating wheel 12 and the smaller-sized second rotating wheel 13 outside the mounting plate 11 and the connecting rod 141.

[0058] Considering the implementation of the solution for the synchronous drive between the larger-sized first rotating wheel 12 and the smaller-sized second rotating wheel 13 as described above, in the synchronous drive pulley set 1 provided in the present application, the second-stage transmission component 153 may include a first pulley 1531, a second pulley 1532, a third pulley 1533, a first synchronous belt 1534, and a second synchronous belt 1535. Among them, the first pulley 1531 can be coaxially driven with the turbine 1522. The second pulley 1532 may include a first pulley groove 1532A and a second pulley groove 1532B located below the first pulley groove 1532A. The radial dimension of the first pulley groove 1532A is larger than that of the second pulley groove 1532B. Exemplarily, the first pulley groove 1532A and the second pulley groove 1532B here are positions for meshing and driving with the corresponding synchronous belts. The pulley groove can also be referred to as a pulley shaft or a connecting shaft. One end of the first synchronous belt 1534 is synchronously meshed and driven with the first pulley 1531, and the other end of the first synchronous belt 1534 is synchronously meshed and driven with the second pulley groove 1532B of the second pulley 1532. One end of the second synchronous belt 1535 is synchronously meshed and driven with the third pulley 1533, and the other end of the second synchronous belt 1535 is synchronously meshed and driven with the first pulley groove 1532A of the second pulley 1532.

[0059] Combined with the specific end position limitations of the foregoing first rotating wheel 12 and second rotating wheel 13, the first pulley 1531 can be located at the fourth end 132 of the second rotating wheel 13, the second pulley 1532 can be located at the second side 112 of the mounting plate 11, and the third pulley 1533 can be located at the second end 122 of the first rotating wheel 12.

[0060] Exemplarily, the second-stage transmission component 153 can adopt the above-described synchronous belt drive method, or alternatively, a gear meshing drive method can also be adopted.

[0061] Considering the forming structures of the pulleys and the rotating wheels, in the synchronous drive pulley set 1 provided by the present application, the first pulley 1531 can be integrally formed with the second rotating wheel 13, or the first pulley 1531 can be detachably connected to the second rotating wheel 13; in addition, the third pulley 1533 can be integrally formed with the first rotating wheel 12, or the third pulley 1533 can be detachably connected to the first rotating wheel 12.

[0062] When the detachable connection method is adopted, it can be any one of screw connection, bolt connection, shaft-hole mating locking connection, snap connection or buckle connection. When integrally formed, the first pulley 1531 and the second rotating wheel 13 can adopt any one of injection molding integral forming, die-casting integral forming or 3D printing integral forming according to different material selections.

[0063] Considering the rotatable connection solution of the connecting rod 141 to the first rotating wheel 12 through the first cap assembly 143, in the synchronous drive pulley set 1 provided by the present application, the first cap assembly 143 includes a first upper rotating body 1431 and a first lower rotating body 1432. The first upper rotating body 1431 is coaxially rotatably connected above the first lower rotating body 1432. The first upper rotating body 1431 is slidably connected to one end of the connecting rod 141, and the first lower rotating body 1432 is connected to the outside of the first rotating wheel 12; in this way, through the rotational connection of the first upper rotating body 1431 relative to the first lower rotating body 1432, the telescopic movement or swinging movement of the connecting rod 141 relative to the outside of the first rotating wheel 12 can be realized.

[0064] Considering the rotatable connection solution of the connecting rod 141 to the second rotating wheel 13 through the second cap assembly 142, in the synchronous drive pulley set 1 provided by the present application, the second cap assembly 142 includes a second upper rotating body 1421 and a second lower rotating body 1422. The second upper rotating body 1421 is coaxially rotatably connected above the second lower rotating body 1422. The second upper rotating body 1421 is connected to the other end of the connecting rod 141, and the second lower rotating body 1422 is connected to the outside of the second rotating wheel 13; in this way, through the rotational connection of the second upper rotating body 1421 relative to the second lower rotating body 1422, the telescopic movement or swinging movement of the connecting rod 141 relative to the outside of the second rotating wheel 13 can be realized.

[0065] Exemplarily, the first upper rotating body 1431, the first lower rotating body 1432, the second upper rotating body 1421 and the second lower rotating body 1422 are all constructed as rotating body structures. The rotating body structure can adopt a cylindrical structure or a conical structure. Exemplarily, when adopting a cylindrical structure, it can be one of a cylindrical structure or a polygonal cylindrical structure.

[0066] Considering the specific installation positions of two rotating wheels on the mounting plate 11, in the synchronous transmission wheel set 1 provided by the present application, a first hole A and a second hole B are respectively penetrated along the thickness direction between the inner side and the outer side of the mounting plate 11, and the first hole A and the second hole B are arranged separately at intervals along the radial direction of themselves; the first rotating wheel 12 is installed in the first hole A, the first rotating wheel 12 includes a first end 121 and a second end 122, the first end 121 protrudes out of the outer side of the mounting plate 11, and the second end 122 protrudes out of the inner side of the mounting plate 11; the second rotating wheel 13 is installed in the second hole B, the second rotating wheel 13 includes a third end 131 and a fourth end 132, the third end 131 protrudes out of the outer side of the mounting plate 11, and the fourth end 132 protrudes out of the inner side of the mounting plate 11.

[0067] The present application does not limit the hole shape structure of the first hole A, the first hole A can be a shape adapted to the shape of the first rotating wheel 12, the present application also does not limit the hole shape structure of the second hole B, and the second hole B can be a shape adapted to the shape of the second rotating wheel 13.

[0068] Furthermore, the first end 121 of the first rotating wheel 12 has a first annular track 1211, the second cap assembly 142 is connected to the first annular track 1211, the third end 131 of the second rotating wheel 13 has a second annular track 1311, and the first cap assembly 143 is connected to the second annular track 1311.

[0069] Exemplarily, the first annular track 1211 can be a decorative part, and the second annular track 1311 can also be a decorative part, which can be a decorative part with texture, pattern, color or brightness.

[0070] In this way, during the rotation of the two rotating wheels, the connecting rod 141 can swing and move between them, and the rotation of the first annular track 1211 and the second annular track 1311 can form a better display effect.

[0071] Considering that two rotating wheels with different sizes can achieve the effect of synchronous transmission, in the synchronous transmission wheel set 1 provided by the embodiment of the present application, the shape of the first annular track 1211 is the same as the shape of the second annular track 1311, and the circumferential dimension of the first annular track 1211 and the circumferential dimension of the second annular track 1311 are in a multiple relationship.

[0072] Exemplarily, when the first annular track 1211 adopts a circular structure, the second annular track 1311 adopts a circular structure in a multiple relationship with the first annular track 1211. Combining with the structure of the driving assembly 15, a solution can be obtained in which both ends of the connecting rod 141 swing and move along the first annular track 1211 or the second annular track 1311 through the first cap assembly 143 and the second cap assembly 142 respectively.

[0073] It is considered that the synchronous drive pulley set 1 provided in the embodiment of the present application is installed in the split box of the television device, and it can achieve better other functions suitable for the application of the television device during rotation. Exemplarily, an electronic component is sleeved on the second rotating wheel 13 along its axial direction, and the second annular track 1311 is arranged around the outer periphery of the electronic component to expose and display the electronic component. Exemplarily, the electronic component can be a speaker, and exemplarily, the speaker can be a sound box.

[0074] In this way, the second annular track 1311 can be used as a rotatable decorative part of the sound box.

[0075] Further considering the installation stability of each structure inside the mounting plate 11, the synchronous drive pulley set 1 provided in the embodiment of the present application further includes a first limit support 17, a second limit support 18, and a third limit support 19. The first limit support 17 is used to limit and install the drive motor 151 at a first preset position inside the mounting plate 11. The second limit support 18 is used to limit and install the turbine 1522 and the first pulley 1531 at the position of the second hole B. The third limit support 19 is used to limit and install the second pulley 1532 at a second preset position inside the mounting plate 11; the second preset position is located between the first hole A and the second hole B, and the first preset position is arranged close to the second hole B.

[0076] The present application does not limit the specific positions of the first preset position and the second preset position, and they can be set according to actual application requirements.

[0077] Considering the control scheme of the drive motor 151, the synchronous drive pulley set 1 provided in the present application further includes a motor drive board 16. The motor drive board 16 is installed on the second side 112 of the mounting plate 11, and the motor drive board 16 is electrically connected to the drive motor 151 to provide a start signal or a stop signal for the drive motor 151.

[0078] When the appearance of the split box consists of two rotating wheels, and the two rotating wheels are connected by a connecting rod 141, the presented appearance effect is that the two rotating wheels achieve synchronous rotation through the connecting rod 141. Since there is a sound box arranged inside the first rotating wheel 12, the position diameters of the connection fulcrums of the first rotating wheel 12 and the second rotating wheel 13 are quite different. The prerequisite for the connecting rod 141 to be able to achieve synchronous transmission is that the rotation diameters of the two ends of the connecting rod 141 for rotational movement are the same. On the premise that the appearance ratio cannot be changed, when the driving pulley B rotates, the driving pulley A can only swing left and right under drive and cannot achieve the effect of synchronous rotation, failing to meet the requirements of the appearance design.

[0079] After adopting the solution of the synchronous drive pulley set 1 of the embodiment of the present application, in order to achieve the synchronous rotation of the two rotating wheels, the connecting rod 141 that can be visually seen on the appearance needs to discard its actual transmission function, and other synchronous transmission devices are added inside the mounting plate 11. A space is reserved inside the first cap assembly 143 to enable the connecting rod 141 to slide telescopically to prevent jamming during the internal driving rotation process, that is, the connecting rod 141 passes through the side surface of the first cap assembly 143 and is slidably connected to the first cap assembly 143. In this way, the effect of synchronous rotation of two different rings driven by the connecting rod 141 can be achieved on the appearance.

[0080] Among them, the first rotating wheel 12 and the second rotating wheel 13 are both divided into different structures located inside and outside the mounting plate 11, and are separated by a split box housing in the middle. On the appearance surface is the synchronous transmission structure between the connecting rod 141 and the adjacent two rotating wheels, and inside is the synchronous pulley transmission mechanism. The speaker is installed inside the second rotating wheel 13.

[0081] In addition, the second rotating wheel 13 can be understood to have a three-layer structure, which can be successively stacked by an appearance decorative ring (that is, the second annular track 1311), the first pulley 1531 and the turbine 1522. The motor output is assembled with a worm 1521, and the worm 1521 drives the turbine 1522 to rotate. The second rotating wheel 13 rotates through each pulley and a variable-speed wheel with a variable-speed function (that is, the second pulley 1532). The belt therein can be selected as a synchronous belt, which can ensure a fixed rotation tooth ratio between the second rotating wheel 13 as the driving wheel and the second pulley 1532 as the variable-speed wheel; the variable-speed wheel is composed of two pulleys with different numbers of teeth (that is, including two grooves with different radial dimensions). When the variable-speed wheel rotates, it drives the driven wheel to rotate through the synchronous belt. By adjusting the tooth ratio of the variable-speed wheel and the two pulleys, the rotation speeds of the driving wheel and the driven wheel can be regulated, and finally the rotation speeds of the two appearance wheels can be ensured to be exactly the same; the driven wheel (that is, the second rotating wheel 13) can be fixed by an ultra-thin outer ring bearing, and a speaker or a sound generating unit or a speaker can be assembled in the hollow part inside, so as to achieve the effect of the outer ring of the speaker rotating on the appearance; if a speaker needs to be arranged at the position of the driven wheel, the entire device thickness can be controlled within 18 mm by using a conveyor belt, which can greatly save the volume of the speaker compared with the gear transmission structure, so as to achieve a better sound effect; by adjusting the length of the conveyor belt, the position of the variable-speed wheel can be flexibly adjusted, and at the same time, the rotation speed ratio of the two rotating wheels is not affected, which is convenient for the layout of other internal structural parts; the synchronous belt has a better silent effect than other driving methods such as gear and rack meshing and turbine 1522 and worm 1521 meshing, and has less interference with the speaker sound effect.

[0082] In summary, adopting the solution of the synchronous drive pulley set 1 of the present application, through the hidden belt transmission mechanism (i.e., the drive assembly 15 located inside the mounting plate 11), the appearance effect of different-diameter rotating wheels driven to rotate by the connecting rod 141 or the linkage mechanism, which cannot be physically achieved, is realized; the ultra-thin transmission mechanism of the present application rarely occupies the internal space of the speaker, realizing the effect of the outer ring rotation of the speaker or the sound generating unit or the speaker; in addition, the application of the synchronous belt can achieve long-distance transmission while saving internal space and not affecting the layout of other structures.

[0083] The embodiment of the present application also provides a television device, which includes the above-mentioned synchronous drive pulley set 1 and also includes a split box. The synchronous drive pulley set 1 is limited and installed on the split box through the mounting plate 11, and the connecting components 14 are all exposed on the surface of the split box. All the effects of the aforementioned synchronous drive pulley set 1 can be achieved, and details are not described herein again.
