Description

Technical Field

[0001] This utility model relates to the field of mobile auxiliary device technology, specifically a mobile auxiliary device for stage lighting and sound. Background Technology

[0002] Stage lighting and sound systems refer to specific sound systems used on a stage. Currently, stage lighting and sound systems are relatively large in size, and most of them are placed directly on the stage. Therefore, auxiliary moving devices are needed to assist in moving these large stage lighting and sound systems.

[0003] A search revealed a patent, CN219478087U, which discloses a mobile auxiliary device for stage lighting and sound systems. The device includes a base with an internal lifting mechanism. This mechanism comprises a first servo motor mounted on the left side wall of the base via a motor mount. The power output of the first servo motor is connected to a first threaded rod via a coupling. A movable plate is threaded onto the circumferential surface of the first threaded rod. Connecting blocks are located at both ends of the upper surface of the movable plate. A first support rod is hinged to the upper end of each of the two connecting blocks via a hinge shaft. This lifting mechanism allows the speaker unit to be raised and lowered to different heights. Furthermore, a first and second limiting mechanism automatically transports the speaker unit, facilitating installation and disassembly without requiring workers to climb or manually move it, thus reducing workload and making the device more convenient, efficient, and safe.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe how the speaker body moves up and down by moving the mounting plate. However, in actual stage setup, the position of the speaker body on the stage is uncertain, so the speaker body may need to be adjusted on the stage. The aforementioned comparative documents can only move the speaker body to the edge of the stage. When it is necessary to move the speaker body away from the edge of the stage, staff still need to move the relatively heavy speaker body, thus reducing the overall range of movement of the stage lighting and speaker body by the movement auxiliary device. Therefore, there is an urgent need in the art to improve the movement auxiliary device for stage lighting and sound to overcome the shortcomings of the prior art. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7A mobile auxiliary device for stage lighting and sound includes a first mobile base 1, with several first mobile wheels 3 fixedly installed on the lower part of the first mobile base 1. A first vertical plate 2 is fixedly connected to one side of the first mobile base 1. A second mobile base 4 is provided on the upper surface of the first mobile base 1. A second vertical plate 5 is provided on one side of the second mobile base 4. An equipment body 6 is placed on the upper surface of the second mobile base 4. Several second mobile wheels 7 are fixedly installed on the lower surface of the second mobile base 4. A symmetrical moving groove 8 adapted to the second mobile wheels 7 is opened on the upper surface of the first mobile base 1. A fixed seat 12 for supporting the second mobile base 4 is slidably connected to one side of the first vertical plate 2. A first driving unit 9 for driving the fixed seat 12 to move up and down is provided on the upper part of the first vertical plate 2. A second driving unit 10 for moving the second mobile base 4 out of the first mobile base 1 is provided at one end of the fixed seat 12. A clamping and limiting unit 11 for limiting and fixing the equipment body 6 is provided on the upper surface of the second mobile base 4.

[0030] Specifically, when the device body 6 needs to be moved, it is fixedly mounted on the second movable base 4 by the clamping and limiting unit 11, and moved by the first movable base 1 equipped with the first movable wheel 3. When the device body 6 needs to be moved to a stage with a certain height, the first movable base 1 is moved to the side of the stage, and the first drive unit 9 is activated. The first drive unit 9 drives the fixed base 12 to move upward along the first vertical plate 2. The fixed base 12 drives the second movable base 4 to move upward, moving the position of the second movable wheel 7 to a position that matches the stage position. The second drive unit 10 is activated, and the second drive unit 10 drives the second movable base 4 to move on the fixed base 12, and then disengages the second movable base 4 from the fixed base 12 and the first movable base 1. At this time, the second movable wheel 7 can move within the movable groove 8. The second movable wheel 7 moves to the stage, and by pushing the second vertical plate 5 to continue moving the second movable base 4, the device body 6 can be moved on the stage. This increases the range of movement of the device body 6 and improves the applicability of the overall moving auxiliary device. The device body 6 is specifically a stage sound system.

[0031] As a technical optimization of this utility model, the first drive unit 9 includes a first drive motor 13 fixedly installed on the upper part of the first vertical plate 2. The opposite sides of the first vertical plate 2 are provided with a clearance opening 15 adapted to one end of the fixed seat 12. The opposite sides of the fixed seat 12 near the first vertical plate 2 are fixedly installed with first sliding blocks 14. The opposite side walls of the clearance opening 15 are provided with first sliding grooves 16 adapted to the first sliding blocks 14. The first sliding grooves 16 are rotatably connected to the first lead screws 17 that pass through the upper part of the first vertical plate 2. The upper sides of the two first lead screws 17 are fixedly installed with transmission wheels 18. The sides of the two transmission wheels 18 are sleeved with a transmission belt 19 for transmission. The first drive motor 13 drives one of the first lead screws 17 to rotate. The first lead screw 17 passes through the first sliding block 14 and is threadedly connected to it.

[0032] Specifically, when it is necessary to move the equipment body 6 up and down, the first drive motor 13 is started. The output end of the first drive motor 13 drives one of the first lead screws 17 to rotate. The transmission wheel 18 on the upper side of the first lead screw 17 drives the transmission belt 19 to rotate. The transmission belt 19 drives the other transmission wheel 18 to rotate, and then the two first lead screws 17 rotate simultaneously. When the first lead screw 17 rotates, it drives the first sliding block 14 to slide in the first sliding groove 16. At this time, one end of the fixed seat 12 moves in the clearance opening 15, thereby achieving the effect of moving the fixed seat 12 up and down, which makes it easier to move the equipment body 6 onto the stage.

[0033] As a technical optimization of this utility model, the second drive unit 10 includes a second drive motor 20 fixedly installed at one end of the fixed base 12, a second sliding block 22 fixedly connected to the lower surface of the second movable base 4, a placement groove 21 adapted to the fixed base 12 on the upper surface of the first movable base 1, a second sliding groove 38 adapted to the second sliding block 22 on the end of the fixed base 12 away from the second drive motor 20, and a second lead screw 23 rotatably connected in the second sliding groove 38, one end of which is fixedly installed to the output end of the second drive motor 20, the second lead screw 23 passing through the second sliding block 22 and threadedly connected to it.

[0034] Specifically, when the fixed base 12 moves to a position that matches the stage height, the second drive motor 20 is started. The output end of the second drive motor 20 drives the second lead screw 23 to rotate. When the second lead screw 23 rotates, it drives the second sliding block 22 located in the second sliding groove 38 to move. The second sliding block 22 drives the second moving base 4 to move horizontally, thereby moving the second moving base 4 onto the stage until the second sliding block 22 is completely disengaged from the second lead screw 23. Then the second moving base 4 can be pushed to move on the stage. When the equipment body 6 needs to be retracted, the position of the second moving base 4 is moved to match the position of the first moving base 1, and the position of the second sliding block 22 is matched with the second sliding groove 38. The second lead screw 23 reverses to drive the second moving base 4 to move onto the first moving base 1.

[0035] As a technical optimization of this utility model, the clamping and limiting unit 11 includes two clamping bars 24 symmetrically arranged on the upper surface of the second movable base 4. A third sliding block 25 is fixedly installed on the lower side of the clamping bar 24. A third sliding groove 26 adapted to the third sliding block 25 is opened on the upper surface of the second movable base 4. A first adjusting threaded rod 27 is rotatably connected through one side of the second movable base 4. When the first adjusting threaded rod 27 is adjusted, it drives the two third sliding blocks 25 to move towards or away from each other. A first limiting nut 28 is threadedly connected to the side of the first adjusting threaded rod 27.

[0036] Specifically, the device body 6 is placed on the second movable base 4. By rotating the first adjusting threaded rod 27, the threads of the first adjusting threaded rod 27 located on the inner side of the third sliding groove 26 are symmetrical and opposite. When the first adjusting threaded rod 27 rotates, it drives the two third sliding blocks 25 to move towards each other in the third sliding groove 26. The third sliding blocks 25 drive the clamping strips 24 to move, thereby achieving the effect of clamping and fixing the device body 6 with the two clamping strips 24. Then, the first limiting nut 28 is tightened to limit and fix the position of the first adjusting threaded rod 27, which is convenient for limiting and fixing the installation of device bodies 6 of different sizes.

[0037] As a technical optimization of this utility model, two symmetrical fourth sliding blocks 29 are provided on the opposing sides of the two clamping bars 24. A fourth sliding groove 30 adapted to the fourth sliding block 29 is opened on one side of the clamping bar 24. A clamping plate 31 adapted to the device body 6 is fixedly installed on one side of the fourth sliding block 29. A second adjusting threaded rod 32 is rotatably connected through one end of the clamping bar 24. When the second adjusting threaded rod 32 rotates, it drives the two fourth sliding blocks 29 to move towards or away from each other. A second limiting nut 33 is threadedly connected to the side of the second adjusting threaded rod 32.

[0038] Specifically, when the clamping bar 24 does not fully abut against both sides of the equipment body 6, the second adjusting threaded rod 32 is rotated. The threads of the second adjusting threaded rod 32 on the inner side of the fourth sliding groove 30 are symmetrical and opposite. When the second adjusting threaded rod 32 rotates, it drives the two fourth sliding blocks 29 to move towards each other in the fourth sliding groove 30. The fourth sliding blocks 29 drive the clamping plate 31 to move. The clamping plate 31 clamps and fixes the other two sides of the equipment body 6. Then, the second limiting nut 33 and the first adjusting threaded rod 27 are tightened to improve the stability of the equipment body 6 after clamping and fixing, and to be able to clamp and fix equipment bodies 6 of different sizes.

[0039] As a technical optimization of this utility model, a chemical power source 34 and a main controller 35 are fixedly installed on one side of the first vertical plate 2. The first drive motor 13 and the second drive motor 20 mentioned above can be purchased from the market. They are mature technologies and have been fully disclosed. Therefore, they will not be repeated in the specification. The first drive motor 13 and the second drive motor 20 are both equipped with power connection lines. They are electrically connected to the external main controller 35 and the chemical power source 34 through the power lines. The main controller 35 can be a conventional known device such as a computer that plays a control role. The operator controls the first drive motor 13 and the second drive motor 20 by operating the control buttons on the main controller 35.

[0040] As a technical optimization of this utility model, a first push rod 36 is fixedly installed on one side of the first vertical plate 2, and a second push rod 37 is fixedly installed on the upper part of the second vertical plate 5.
