[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figure 1-5 A portable home karaoke machine includes a protective shell 1. The top of the protective shell 1 has a horizontal groove 2. A lifting plate 3 is vertically slidably installed in the horizontal groove 2. A display screen 4 is arranged above the lifting plate 3. The horizontal groove 2 is used to store and protect the display screen 4. The front side of the protective shell 1 has an embedding groove 5. A speaker structure 6 is fixedly installed in the embedding groove 5. The rear side of the protective shell 1 has a mounting groove. The main unit is arranged in the mounting groove. The main unit is electrically connected to the display screen 4 and the speaker structure 6 respectively.
[0028] In this embodiment, side plates 7 are fixedly installed on the upper part of the inner walls on both sides of the transverse groove 2. A lead screw 8 is rotatably installed on the bottom of the side plate 7. The lifting plate 3 is threadedly connected to the two lead screws 8 respectively. A servo motor is fixedly installed on the bottom inner wall of the transverse groove 2. The output shaft of the servo motor is fixedly connected to the bottom end of the lead screw 8 on the right side. The outer side of the lifting plate 3 is slidably connected to the inner wall of the transverse groove 2. A pulley is fixedly sleeved on the outer side of the lead screw 8. The same belt 9 is installed on the two pulleys for transmission. The lifting plate is controlled by the cooperation of the servo motor, the lead screw and the lifting plate. A sealing strip is fixedly installed below the side plate. The sealing strip is in movable sealing contact with the bottom of the door panel to improve the sealing performance at the connection between the door panel and the side plate.
[0029] In this embodiment, storage slots are provided on both the left and right sides of the protective shell 1. A storage frame 19 is horizontally slidably installed in the storage slot. The storage frame 19 includes multiple partitions 20, each of which includes a diagonal segment and a flat segment. The storage frame is used to place some small components that come with the karaoke machine, such as microphones, remote controls, USB / SD cards, and headphones.
[0030] In this embodiment, a door panel 10 is mounted on the top of the side panel 7 via a hinge. An extension plate 11 is fixedly mounted on one side of each of the two door panels 10. Both the door panel 10 and the extension plate 11 have rounded corners on one side. A support platform 12 is fixedly mounted on the top of the lifting plate 3. The display screen 4 includes a folding bracket 13. The bottom end of the folding bracket 13 is fixedly connected to the top of the support platform 12. The extension plate and the rounded corners on the extension plate and the door panel are designed to prevent the two door panels from colliding with each other when they rotate, and to ensure a tight fit and improve the sealing of the connection between the two door panels.
[0031] In practical use, by swinging the two door panels upwards, the door panels are flipped and move to abut against the top of the side panels. After the two door panels are flipped, the horizontal slot is opened. Then, through the cooperation of the servo motor, lead screw and lifting plate, the support platform and display screen are driven to move upwards until the top of the support platform is flush with the top of the flipped door panels, so that the support platform and the two door panels form a table, expanding the top usable space of the protective shell, and the display screen is swung upwards for easy use.
[0032] In this embodiment, a connecting cavity 14 connects the storage slot and the transverse slot 2. Gears 15 are rotatably installed on the inner walls of the front and rear sides of the connecting cavity 14. Racks 16 are fixedly installed at the four bottom corners of the lifting plate 3. Racks 17 are vertically slidably installed on the inner walls of the front and rear sides of the connecting cavity 14. Racks 16 and 17 mesh with the corresponding gears 15.

The wedge plate 18 is slidably connected to the top inclined surface of the corresponding storage frame 19.
[0033] To further explain, during the upward movement of the lifting plate, multiple racks move upward. The racks mesh with gears, causing racks and wedges to move downward, which in turn presses against the top slope of the storage frame, moving the storage frame outward towards the protective shell, thus facilitating the removal of items from the storage frame.
[0034] In this embodiment, a guide groove is provided on the bottom inner wall of the storage slot, and a guide plate 21 is fixedly installed on the bottom of the storage frame 19. The guide plate 21 is slidably installed in the corresponding guide groove, and the same return spring 22 is fixedly connected between the guide plate 21 and the inner wall of one side of the corresponding guide groove.
[0035] In this embodiment, right-angle notches are provided at the four bottom corners of the protective shell 1, and casters 23 are fixedly installed in the right-angle notches. The casters 23 are provided with a self-locking mechanism to facilitate the movement of the entire device.
[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
