Description

Technical Field

[0001] The utility model relates to the technical field of stage side car platforms, and particularly relates to a stage side car platform capable of being independently and synchronously driven with precision. Background Art

[0002] In order to enhance the overall sense and gorgeous effect of the stage and meet the visual aesthetic enjoyment of the audience, a large number of LED screens are usually adopted for the background wall, ceiling and floor of the stage in the studio. Some stages even directly extend to the front row position of the auditorium, forming a relatively extended stage, so that the studio becomes a stage performance space completely from the ground to the ceiling. The stage is almost covered by the screen. That is to say, the entire ground, surrounding and ceiling of the stage are light-emitting bodies. Generally speaking, the performance space on the ground is mainly expanded by the extension of the ground car platform board.

[0003] The extension or retraction of the side wings of the stage side car platform is often driven by a hydraulic system actuator, so that the side wings extend outwards to expand the performance space or retract inwards to ensure the minimum performance space. However, in the existing structure, extendable side wings often need to be provided on both sides of the stage. However, if independent hydraulic actuators are used, complex program control is often required to achieve the simultaneous outward extension of the two side wings, and it is not convenient for a single side wing to complete independent outward extension without driving the other side wing to move synchronously, resulting in certain limitations in the movement of the two side wings.

[0004] Therefore, it is very necessary to invent a stage side car platform capable of being independently and synchronously driven with precision to solve the above problems. Content of the Utility Model

[0005] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a stage side car platform capable of being independently and synchronously driven with precision, which solves the problem that in the prior art, extendable side wings often need to be provided on both sides of the stage. However, if independent hydraulic actuators are used, complex program control is often required to achieve the simultaneous outward extension of the two side wings, and it is not convenient for a single side wing to complete independent outward extension without driving the other side wing to move synchronously, resulting in certain limitations in the movement of the two side wings.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A stage side car platform that can be independently and synchronously driven precisely, comprising a car bottom plate, a protection component installed above the middle of the top surface of the car bottom plate, and two screws that are symmetrically rotated and have opposite rotation directions and are synchronously rotated and arranged at symmetrical positions of the protection component. Both side walls of the protection component extend to form side plates at the top ends. Each screw is threadedly sleeved with a slider that can slide along the length direction of the side plate. Side clamping seats are arranged on both side walls of the slider. Longitudinally telescopic first telescopic members are installed on the bottom sides of both side walls of the protection component. A fixed car platform plate that can slide longitudinally along the side wall of the protection component is installed at the top end of the first telescopic member. A moving car platform plate is slidably embedded in the fixed car platform plate in a direction close to or away from the protection component. And a first sliding seat is slidably arranged on the top surface of the car bottom plate along the sliding direction of the moving car platform plate. A longitudinally telescopic second telescopic member is installed at the top end of the first sliding seat. A sliding plate that can be abutted and installed with the bottom end of the moving car platform plate is installed at the top end of the second telescopic member. Rotating rods are rotatably connected to both ends of the sliding plate. A plug post that can be inserted into or disengaged from the side clamping seat is installed at the bottom end of the other end of the rotating rod.

[0008] As a preferred solution of the present utility model, the protection component includes two side protection frames that are symmetrically installed on the middle of the top surface of the car bottom plate and are in contact with each other. A driving member is installed on the outer side wall of one side of the side protection frame through a mounting seat. The output end of the driving member rotatably penetrates the side protection frame and extends into the side protection frame. And a driving gear is installed at one end of the output end of the driving member located inside the side protection frame. A driven gear is meshed and connected to the top of the driving gear. The screws are symmetrically installed on both side walls of the driven gear. And the screws rotatably penetrate the side protection frame.

[0009] As a preferred solution of the present utility model, bottom extension seats are installed at the bottoms of the side walls of the two side protection frames that are away from each other. The bottom end of the first telescopic member is detachably connected to the top end of the bottom extension seat. The top end of the first telescopic member is detachably connected to the bottom surface of the fixed car platform plate through a top extension seat.

[0010] As a preferred solution of the present utility model, a first sliding rail is installed at a position on the top surface of the car bottom plate that adapts to the sliding direction of the moving car platform plate. The first sliding seat is slidably connected to the first sliding rail. The top end of the second telescopic member is detachably connected to the sliding plate through a connecting plate.

[0011] As a preferred solution of the present utility model, a second sliding rail is installed on the bottom surface of the side plate extending in the length direction. A second sliding seat that can slide along the second sliding rail is installed at the top end of the slider.

[0012] As a preferred solution of the present utility model, a top bar that can contact the bottom surface of the moving car platform plate is connected to the top end of the rotating rod.

[0013] As a preferred solution of the present utility model, the longitudinal telescopic time and length of the first telescopic member and the second telescopic member are kept consistent.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0015] In the present utility model, when it is necessary to make two moving vehicle platforms extend outward or retract inward synchronously, it is only necessary to synchronously move down the first telescopic member and the second telescopic member so that the insertion posts are inserted into the side card seats. Subsequently, by driving the two screws to rotate synchronously, the two sliders can be made to move closer to or away from each other synchronously, thereby driving the moving vehicle platforms to extend outward or retract inward within the fixed vehicle platform; when only one-sided moving vehicle platform needs to extend outward or retract inward, it is only necessary to move down the first telescopic member and the second telescopic member on this side so that the insertion posts on this side are inserted into the side card seats, and move up the first telescopic member and the second telescopic member on the other side so that the insertion posts on this side are disengaged from the side card seats. Thus, during the subsequent rotation of the screws, only one end of the one-sided rotating rod slides synchronously with the slider, that is, only one-sided moving vehicle platform extends outward or retracts inward within the fixed vehicle platform, thereby realizing the outward extension or inward retraction of one-sided moving vehicle platform. Finally, whether the insertion posts are inserted into the side card seats is used to determine whether it is one-sided moving vehicle platform that extends outward or retracts inward or both sides of the two moving vehicle platforms that extend outward or retract inward. The sliding distance of the moving vehicle platform can be accurately controlled by the number of rotations of the screws, and finally the independent sliding and synchronous sliding of the two moving vehicle platforms are realized.

Detailed implementation manners

[0023] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0024] The present utility model provides a stage side car platform that can be independently and synchronously driven precisely as Figures 1-5 shown, including a car bottom plate 1, a protection component installed above the middle of the top surface of the car bottom plate 1, and two screws 7 that are symmetrically and synchronously rotated and have opposite rotation directions, which are rotatably arranged at symmetrical positions of the protection component. The top ends of both side walls of the protection component are extended to form side plates 9. Each screw 7 is threadedly sleeved with a slider 8 that can slide along the length direction of the side plate 9. Both side walls of the slider 8 are provided with side clamping seats 10. The bottom sides of both side walls of the protection component are installed with first telescopic members 12 that can be longitudinally telescoped. The top ends of the first telescopic members 12 are installed with a fixed car platform plate 14 that can slide longitudinally along the side wall of the protection component. The moving car platform plate 23 is slidably embedded in the fixed car platform plate 14 in a direction close to or away from the protection component. And a first sliding seat 16 is slidably arranged on the top surface of the car bottom plate 1 along the sliding direction of the moving car platform plate 23. The top end of the first sliding seat 16 is installed with a second telescopic member 17 that can be longitudinally telescoped. The top end of the second telescopic member 17 is installed with a sliding plate 19 that can be abutted and installed with the bottom end of the moving car platform plate 23. Both ends of the sliding plate 19 are rotatably connected with a rotating rod 20. The other end bottom of the rotating rod 20 is installed with an insertion post 21 that can be inserted into or disengaged from the side clamping seat 10. The length of the side plate 9 is the same as the length of the screw 7, so as to prevent the screw 7 from leaking out of the side plate 9.

[0025] The protection component includes two side protection frames 2 that are symmetrically installed on the middle of the top surface of the car bottom plate 1 and are in contact with each other. One side wall of the outside of the side protection frame 2 is installed with a driving member 4 through a mounting seat 3. The output end of the driving member 4 rotatably penetrates the side protection frame 2 and extends into the side protection frame 2. And one end of the output end of the driving member 4 located inside the side protection frame 2 is installed with a driving gear 5. The driving gear 5 is meshed and connected with a driven gear 6 at the top. The screws 7 are symmetrically installed on both side walls of the driven gear 6, and the screws 7 rotatably penetrate the side protection frame 2. The driving member 4 drives the driving gear 5 to rotate, and then drives the meshed and connected driven gear 6 to rotate, and then drives the two screws 7 to rotate synchronously. And the number of rotation turns of the screw 7 can be accurately controlled by the number of rotation turns of the driving gear 5 or the driven gear 6.

[0026] The bottom of both side walls of the two side protection frames 2 that are far away from each other are installed with bottom extension seats 11. The bottom end of the first telescopic member 12 is detachably connected with the top end of the bottom extension seat 11. The top end of the first telescopic member 12 is detachably connected with the bottom surface of the fixed car platform plate 14 through a top extension seat 13. The bottom extension seat 11 can fix the position of the first telescopic member 12 at the side wall of the side protection frame 2, that is, ensure that the fixed car platform plate 14 can only move longitudinally.

[0027] A first slide rail 15 is installed at a position on the top surface of the vehicle floor 1 that is adapted to the sliding direction of the motor vehicle platform 23. The first slide seat 16 is slidably connected to the first slide rail 15. The top end of the second telescopic member 17 is detachably connected to the slide plate 19 through a connecting plate 18. When the two sliders 8 slide towards or away from each other, the first slide seat 16 is driven to slide along the first slide rail 15 in a direction away from or close to the side protection frame 2, that is, the motor vehicle platform 23 is extended outward or retracted inward.

[0028] A second slide rail 24 is installed on the bottom surface of the side plate 9 in the extending length direction, and a second slide seat 25 that can slide along the second slide rail 24 is installed on the top of the slider 8. The second slide seat 25 slides along the second slide rail 24 to prevent the slider 8 from actively rotating.

[0029] The top of the rotating rod 20 is connected with a top strip 22 which can contact the bottom surface of the motor vehicle platform 23. The top strip 22 can increase the contact area between the rotating rod 20 and the motor vehicle platform 23, thereby improving the stability of the motor vehicle platform 23 during the sliding process.

[0030] The longitudinal extension time and length of the second telescopic member 17 of the first telescopic member 12 are kept consistent, which can ensure that the fixed car platform 14 and the moving car platform 23 move up or down synchronously, thereby avoiding interference between the fixed car platform 14 and the moving car platform 23.

[0031] In the present invention, when it is necessary to make the two moving car platforms 23 extend outward or retract inward synchronously, it is only necessary to move the first telescopic member 12 and the second telescopic member 17 downward synchronously to insert the plug post 21 into the side holder 10, and then the two screw rods 7 can be driven to rotate synchronously, so that the two sliders 8 can slide synchronously close to or away from each other, thereby driving the moving car platform 23 to extend outward or retract inward in the fixed car platform 14; when only one side of the moving car platform 23 needs to be extended outward or retracted inward, it is only necessary to move the first telescopic member 12 and the second telescopic member 17 on that side downwardly to insert the plug post 21 on that side into the side holder 10, and the first telescopic member 12 and the second telescopic member 17 on the other side can be driven to rotate synchronously. The upward movement of the retracted part 17 causes the plug post 21 on that side to disengage from the side holder 10, so that in the subsequent rotation of the screw rod 7, only one end of the single-sided rotating rod 20 slides synchronously with the slider 8, that is, only the single-sided EMU platform 23 extends outward or is retracted inward in the fixed vehicle platform 14, thereby realizing the single-sided EMU platform 23 extending outward or being retracted inward, and finally, whether the plug post 21 is inserted into the side holder 10 determines whether the single-sided EMU platform 23 extends outward or is retracted inward or the two EMU platforms 23 on both sides extend outward or are retracted inward, and the sliding distance of the EMU platform 23 can be accurately controlled by the number of rotations of the screw rod 7, thereby realizing the independent sliding and synchronous sliding of the two EMU platforms 23.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
