Description

Technical Field

[0001] This utility model relates to the field of performance equipment technology, and in particular to a performance mobile vehicle. Background Technology

[0002] A mobile performance vehicle, also known as a mobile stage vehicle, is a special type of vehicle that is convenient for mobile performances and can be used as a stage. A loud speaker is usually placed on the stage to attract people to stop and watch. In modern commercial society, mobile performance vehicles are mostly used as a way to carry out performances and promotions at the same time, and can stop at any time to perform.

[0003] Utility model patent application number 202021062685.X discloses a mobile advertising vehicle. This mobile advertising vehicle, by setting up a dustproof mechanism for shielding the display screen, allows the drive component to drive the rotating shaft to rotate in the opposite direction when the advertising vehicle is not in use for a long time. This causes the roller tube to rotate in the opposite direction and release the roller curtain. At this time, the weight of the counterweight beam causes the end of the roller curtain extending outside the roller shutter box to fall down, thereby pulling the roller curtain out of the roller shutter box and unfolding it, thus shielding the display screen. Dust and impurities are blocked by the roller curtain and cannot adhere to the surface of the display screen, ensuring both the cleanliness and hygiene of the display screen and its normal display effect. However, in the process of using the above design, only a single display screen can be used for advertising. When a performance is required, staff must set up a separate venue, which is cumbersome and inconvenient to use.

[0004] Therefore, it is necessary to provide a mobile performance vehicle to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments. Example

[0025] like Figure 1-7As shown, the mobile performance vehicle provided by this utility model includes: a vehicle body 1, a large display screen 2 installed on the front side of the vehicle body 1, which can be used to conveniently promote the performance content and facilitate viewing by passersby; a speaker installed on one side of the large display screen 2, which can enhance the promotional effect of the performance; an extension plate 3 installed below the large display screen 2; multiple handles 7 installed on the front side of the extension plate 3; multiple pulleys 12 installed at the bottom of the extension plate 3; and a T-shaped groove 13 installed inside the vehicle body 1 near the outer side of the pulleys 12. When a performance is needed, the staff can pull the handle 7 to pull the extension plate 3 out of the vehicle body 1, thereby expanding the performance range of the device. The pulley 12 slides inside the T-shaped groove 13, making it easier to pull the extension plate 3 and extend the stage more conveniently. The front side of the pulley 12 is fixed with a threaded ring 11, and multiple bolts 10 are provided on the extension plate 3. The bottom of the bolts 10 passes through the extension plate 3 and is threadedly connected to the vehicle body 1, thereby fixing the extension plate 3 and the vehicle body 1, increasing the stage area for performances and facilitating performances. Example

[0026] like Figure 2 , 4 As shown in Figure 5, two support blocks 9 are welded to one side of the vehicle body 1 and the extension plate 3. The support blocks 9 are provided with hanging holes. The extension plate 3 is connected to one side of the vehicle body 1 with a hanging rope assembly. The hanging rope assembly is used to assist in fixing the extension plate 3. The hanging rope assembly includes a steel wire rope 14. Both ends of the steel wire rope 14 are fixed with hooks 21. The hooks 21 can be hung in the hanging holes on the support blocks 9. The extension plate 3 can be more stable under the pull of the two steel wire ropes 14.

[0027] Furthermore, the rope assembly also includes a rope adjusting mechanism 15, which is used to adjust the length of the wire rope 14. The rope adjusting mechanism 15 includes an outer mounting frame 16, and an inner mounting frame 17 slides inside the outer mounting frame 16. The two outer sides of the inner mounting frame 17 are loosely connected to the two inner sides of the outer mounting frame 16. An adjusting wheel 18 is rotatably mounted inside the inner mounting frame 17. The wire rope 14 passes through the inner mounting frame 17 and is mounted on the adjusting wheel 18. One side of the inner mounting frame 17 rotates... A second lead screw 19 is movably installed, one end of which extends to the outside of the outer mounting frame 16 and is threadedly connected to the outer mounting frame 16. By rotating the second lead screw 19, the mounting frame 17 can be moved. The movement of the mounting frame 17 drives the adjusting wheel 18 to move, thereby adjusting the length of the steel wire rope 14 exposed outside the outer mounting frame 16. Two sets of limiting wheels 20 are rotatably arranged inside the outer mounting frame 16. The steel wire rope 14 passes through the limiting wheels 20, and the limiting wheels 20 limit the steel wire rope 14.

[0028] When using the wire rope 14 to assist in fixing the extension plate 3, the length of the wire rope 14 needs to be longer than the distance between the two corresponding bearing blocks 9 so that the hook 21 can be hung in the hanging hole on the bearing block 9. However, if the length of the wire rope 14 is longer than the distance between the two corresponding bearing blocks 9, the auxiliary fixing of the extension plate 3 will fail. In this case, in this embodiment, the second screw 19 can be rotated to move the inner mounting frame 17 to adjust the length of the wire rope 14. That is, when using it, first hang the hooks 21 at both ends of the wire rope 14 on the bearing block 9, and then rotate the second screw 19. The inner mounting frame 17 moves with the adjusting wheel 18, and the adjusting wheel 18 drives the wire rope 14 to move at the same time, so as to collect the excess of the wire rope 14 into the outer mounting frame 16, thereby achieving the purpose of tightening the wire rope 14 and thus achieving the effect of assisting in fixing the extension plate 13. Example

[0029] like Figure 6-7 As shown, an auxiliary display screen 4 is installed on the top of the vehicle body 1. The auxiliary display screen 4 allows spectators or passersby behind the device to see the performance promotional content, thereby expanding the promotional effect of the performance. Inside the vehicle body 1, near the lower part of the auxiliary display screen 4, a set of sliders 5 are installed. The sliders 5 are slidably installed on the top of the vehicle body 1. A first lead screw 6 is threaded through the sliders 5 and connected to the first lead screw 6. A motor 8 is installed on one side of the vehicle body 1. The rotating shaft of the motor 8 is connected to the first lead screw 6. In use, the motor 8 can be started, and the motor 8 drives the first lead screw 6 to rotate, thereby moving the sliders 5 and the auxiliary display screen 4. The moving auxiliary display screen 4 can further improve the promotional effect of the performance, and the position of the auxiliary display screen 4 can be adjusted as needed to ensure that the spectators behind can clearly see the performance content. Example

[0030] like Figure 1-3 As shown, the auxiliary display screen 4 and the slider 5 are connected by a damping hinge, meaning that the auxiliary display screen 4 can rotate to a suitable angle and maintain the rotated state. When the auxiliary display screen 4 is not working, it can be rotated to a horizontal state, thus reducing the overall height of the vehicle.

[0031] The working principle of the mobile performance vehicle provided by this utility model is as follows:

[0032] In use, after moving the device to the designated location, the operator can pull the handle 7 to pull the extension plate 3 out of the vehicle body 1. The pulley 12 drives the threaded ring 11 to pass through the T-slot 13. Then, the operator can pass the bolt 10 through the through hole through the extension plate 3 and the vehicle body 1 and connect it with the threaded ring 11 to fix the extension plate 3 and the vehicle body 1. Next, the hooks 21 at both ends of the wire rope 14 are hung on the bearing block 9. Then, the second screw 19 is rotated, and the inner mounting frame 17 moves with the adjusting wheel 18. The adjusting wheel 18 simultaneously drives the wire rope 14 to move, thereby storing the excess wire rope 14 inside the outer mounting frame 16, thereby achieving the purpose of tightening the wire rope 14 and thus achieving the effect of assisting in fixing the extension plate 13. The motor 8 drives the first screw 6 to rotate, thereby driving the slider 5 and the auxiliary display screen 4 to move. The moving auxiliary display screen 4 can further improve the publicity effect of the performance, and the position of the auxiliary display screen 4 can be adjusted as needed to ensure that the audience at the back can clearly see the content of the performance.

[0033] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
