The terms "mounted," "connected," "fixed," and the like are to be construed broadly, and for example, "connected" may be a fixed connection, a removable connection, or an integral connection; "coupled" may be direct or indirect through an intermediary. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
As shown in fig. 1 to 3, the bidirectional telescopic platform for a laser television provided in this embodiment includes a circumferential frame 1, a first support plate 2, a second support plate 3, a first driving mechanism 4, and a second driving mechanism 5.
Specifically, the frame 1 encloses a receiving space with circumferential side walls, and the frame 1 is rectangular as a whole and has a first side and a second side which are oppositely arranged and open. The first driving mechanism 4 and the second driving mechanism 5 are arranged side by side in an accommodating space enclosed by the frame 1. The first support plate 2 covers the open first side, and the first support plate 2 can be extended from the frame 1 in a first direction (left side as viewed in fig. 2) by the first driving mechanism 4. The second support plate 3 covers the above-mentioned open second side, and the second support plate 3 can be extended in a second direction (right side as viewed in fig. 2) opposite to the first direction by the frame 1 by the second driving mechanism 5.
Based on the structure, the first support plate 2 or the second support plate 3 can be taken as a bearing platform for placing the projection end of the laser television. The first drive mechanism 4 and the second drive mechanism 5 are arranged side by side (in the same plane in the receiving space) with the directions of movement of the first support plate 2 and the second support plate 3 being opposite. In actual use, if the first support plate 2 is used as a carrier, the second support plate 3 is fixedly placed at a certain position (for example, on a television set), the first support plate 2 is driven by the first driving mechanism 4 to extend in the first direction, and the frame 1 is driven by the second driving mechanism 5 to extend in the first direction (actually, the second driving mechanism 5 may also be understood to extend in the second direction relative to the frame 1 based on the relative motion). Therefore, the total protrusion of the first support plate 2 is equal to the sum of the protrusion of itself and the protrusion of the frame 1 (or the protrusion of the second support plate 3, as understood). Therefore, the movement distance of the bidirectional telescopic platform is increased on the premise of not increasing the length, the width and the thickness of the platform (frame). The bidirectional telescopic platform for the laser television provided by the embodiment can not increase the placing space, and the telescopic stroke is longer. Further, it should be understood by those skilled in the art that in the present embodiment, the frame 1 is rectangular as a whole, but the present invention is not limited to the shape of the frame 1, and for example, the frame 1 may also be circular or regular polygon.
Further, after the first support plate 2 is extended from the frame 1 toward the first direction to a predetermined position by the first driving mechanism 4, the second support plate 3 is extended from the frame 1 toward the second direction by the second driving mechanism 5. Alternatively, after the second support plate 3 is extended from the frame 1 toward the second direction to the predetermined position by the drive of the second drive mechanism 5, the first support plate 2 is extended from the frame 1 toward the second direction by the drive of the second drive mechanism 5.
Further, the first support plate 2 can open or close the first side by the first driving mechanism 4. The second support plate 3 can open or close the second side by the driving of the second driving mechanism 5.
Therefore, when the first support plate 2 and the second support plate 3 are located at the closed position, the frame 1, the first support plate 2 and the second support plate 3 actually enclose a closed accommodating space, and the first driving mechanism 4 and the second driving mechanism 5 are located in the closed accommodating space more safely and more beautifully
Further, the maximum protrusion of the first support plate 2 and the second support plate 3 with respect to the frame 1 is the same. Therefore, the same effect can be obtained regardless of whether the first support plate 2 or the second support plate 3 is used as the platform, that is, the telescopic platform can be used without distinguishing the front and the back.
Further, referring to fig. 3, the frame 1 has a first side wall 11 and a second side wall 12 opposite to each other, and the first driving mechanism 4 includes a first lead screw 41, a first rotating motor 42, and a first nut 43. Wherein both ends of the first lead screw 41 are respectively provided to the first and second sidewalls 11 and 12 of the frame 1, and the first rotating motor 42 enables the first lead screw 41 to rotate with respect to the frame 1. The first rotating motor 42 may be provided on either the first side wall 11 or the second side wall 12. The first nut 43 is provided on the first lead screw 41, and is capable of moving linearly along the first lead screw 41 in accordance with the rotation of the first lead screw 41. The first support plate 2 is connected (directly or indirectly associated) with a first nut 43 so that it can project towards a first direction following the movement of the first nut 43.
Similarly, the second driving mechanism 5 includes a second lead screw 51, a second rotating motor 52, and a second nut (hidden in fig. 3). Wherein, two ends of the second lead screw 51 are respectively disposed on the first side wall 11 and the second side wall 12 of the frame 1, and the second rotating motor 52 enables the second lead screw 51 to rotate relative to the frame 1. The second lead screw 51 and the first lead screw 41 are arranged in parallel. The second rotating motor 52 may be disposed on either the first side wall 11 or the second side wall 12. The second nut is provided on the second lead screw 51, and is capable of moving linearly along the second lead screw 51 in accordance with the rotation of the second lead screw 51. The first support plate 2 is connected (directly or indirectly associated) with the second nut so that it can project towards the second direction following the movement of the second nut 53.
Further, the first lead screw 41 and the second lead screw 51 are symmetrically arranged at the middle position of the accommodating space (symmetrically located at both sides of the center line of the frame as shown in fig. 3). The first driving mechanism 4 further includes at least one first rail 44 having both ends respectively disposed on the first side wall 11 and the second side wall 12, and a first slider 45 disposed on the first rail 44. The first support plate 2 is connected to both the first nut 43 and the first slider 45. The second driving mechanism 5 further includes at least one second rail 54 having both ends respectively provided to the first side wall 11 and the second side wall 12, and a second slider 55 provided on the second rail 54. The second support plate 3 is connected to both the second nut and the second slider 55. The first lead screw 41, the second lead screw 51, the first rail 44 and the second rail 54 are arranged side by side in a receiving space enclosed by the frame 1.
Based on the above structure, the first support plate 2 is simultaneously supported/guided by the first nut 43 and the first slider 45, enabling a smoother movement thereof. The second support plate 3 also has the same effect. The first lead screw 41, the second lead screw 51, the first guide rail 44 and the second guide rail 54 are arranged side by side (i.e. the four are in the same plane in the accommodating space), so that the movement distance of the bidirectional telescopic platform can be increased without increasing the length, width and thickness of the platform (frame).
It will be appreciated by those skilled in the art that the first and second slides 45, 55 are followers that slide along the first and second rails 44, 54 as the first and second nuts 43, 55 move. In this embodiment, the first guide rail 44 and the second guide rail 54 are guide rods, and the first sliding member 45 and the second sliding member 55 are provided with through holes having a diameter equivalent to that of the guide rods, so as to meet the requirement of sliding. Otherwise, the first 44 and second 54 rails may represent rails like rails for a train, and the first 45 and second 55 slides may represent wheels capable of traveling along the rails.
In the embodiment shown in fig. 3, the first guide rails 44 have two and are respectively located on both sides of the first lead screw 41 and the second lead screw 51. The second guide rails 54 are also provided in two numbers and are respectively located on both sides of the first lead screw 41 and the second lead screw 51. The distance between the two first rails 44 is equal to the distance between the two second rails 54. Specifically, the second rail 54 is closer to the outside of the frame 1 on the left side as viewed in fig. 3, and the first rail 44 is closer to the outside of the frame 1 on the right side as viewed in fig. 3, i.e., it can also be understood that the first rail 44 and the second rail 54 are arranged alternately. Therefore, on the premise of not increasing the length, width and thickness of the platform (frame), the first support plate 2 and the second support plate 3 can be supported to the maximum extent, so that the movement of the platform is more stable.
Preferably, the first support plate 2 reaches a maximum protruding position towards the first direction when the first nut 43 is proximate to the first side wall 11. When the second nut is proximate to the second side wall 12, the second support plate 3 reaches a maximum protruding position towards the second direction. The above-mentioned proximity means that the first and second nuts 43 and 51 move to the extreme positions close to the first and second side walls 11 and 12 when the first and second lead screws 41 and 51 are moved, and it is not necessary that the first nut 43 contacts the first side wall 11 or the second nut contacts the second side wall 12.
Further, the first driving mechanism 4 further includes a first connecting plate 46 connected to the first nut 43 and the first sliding member 45, the first connecting plate 46 is provided with a first groove for accommodating the first rotating motor 42 and/or the second rotating motor 52, and the first supporting plate 2 is fixedly connected to the first connecting plate 46, so that when the first supporting plate 2 reaches the maximum extending position, the first groove 46 can accommodate the first rotating motor 42 and/or the second rotating motor 52. Similarly, the second driving mechanism 5 further includes a second connecting plate 56 connected to the second nut and the second slider 55, the second connecting plate 56 is provided with a second groove for accommodating the first rotating motor 42 and the second rotating motor 52, and the second supporting plate 3 is fixedly connected to the second connecting plate 56, so that when the second supporting plate 3 reaches the maximum protruding position, the second groove can accommodate the first rotating motor and/or the second rotating motor 52.
It will be appreciated by those skilled in the art that the first and second connecting plates 46, 56 are recessed to prevent interference with the drive mechanism, thereby allowing greater travel of the first and second connecting plates 46, 56 without increasing the length, width and thickness of the platform (frame). In addition, the connection of the first support plate 2 and the second support plate 3 with the first connecting plate 46 and the second connecting plate 56, respectively, can also ensure that they move more smoothly.
In other embodiments of the present invention, the frame 1 has a first side wall 11 and a second side wall 12 arranged opposite to each other. The first drive mechanism 4 comprises a first slide rod 41 ', a first air cylinder or first linear motor 42 ', a first slide 43 '. Wherein, two ends of the first sliding bar 41' are respectively arranged on the first side wall 11 and the second side wall 12 of the frame 1. The first cylinder or the first linear motor 42' may be provided on either the first sidewall 11 or the second sidewall 12. The first slider 43 'is disposed on the first slide bar 41' and can move linearly along the first slide bar 41 'under the driving of the first cylinder or the first linear motor 42'. The first support plate 2 is connected (directly or indirectly associated) to the first slider 43 'so as to be able to project towards the first direction following the movement of the first slider 43'.
Similarly, the second drive mechanism 5 comprises a second slide rod 51 ', a second cylinder or second linear motor 52', a second slider (hidden in fig. 3). Wherein, two ends of the second sliding bar 51' are respectively arranged on the first side wall 11 and the second side wall 12 of the frame 1. A second cylinder or a second linear motor 52' may be provided on either the first sidewall 11 or the second sidewall 12. The second slider is disposed on the second slide bar 51 ' and can move linearly along the second slide bar 51 ' under the driving of the second cylinder or the second linear motor 52 '. The second support plate 2 is connected (directly or indirectly associated) to the second slider so as to be able to project towards the second direction following the movement of the second slider.
The above-mentioned modifications can be applied to the present embodiment, for example, the first slide bar 41 'and the second slide bar 51' are symmetrically arranged at the middle position of the accommodating space.
