[0045] The display device in this embodiment comprises:

[0046] The box body 1 is provided with a placing groove 11, and the box body 1 is provided with a driving mechanism and a sound producing assembly; the driving mechanism is in transmission connection with the sound producing assembly;

[0047] The lighter 2 is arranged in the placing groove 11;

[0048] The first gear 4 is arranged on the top surface of the lighter 2, and the first gear 4 is in transmission connection with the driving mechanism;

[0049] The limiting plate 22 is arranged on the surface of the lighter 2;

[0050] The movable plate 3 is provided with a limiting groove 32 matched with the limiting plate 22 on the bottom surface, and the movable plate 3 is installed on the limiting plate 22 through the limiting groove 32;

[0051] The first protruding block 5 is arranged on the top surface of the first gear 4, and the first protruding block 5 has a first inclined sliding surface;

[0052] The second protruding block 6 is arranged on the bottom surface of the movable plate 3, and the second protruding block 6 has a second inclined sliding surface, and the first protruding block 5 is in transmission connection with the second protruding block 6;

[0053] When the driving mechanism drives the first gear 4 to rotate, the first protruding block 5 follows the movement, so that the first inclined sliding surface contacts with the second inclined sliding surface, and the movable plate 3 is pushed to slide upward or downward along the first inclined sliding surface.

[0054] The driving mechanism in the box body 1 is used for driving the first gear 4 and the sound producing assembly; the sound producing assembly and the first gear 4 are synchronously operated; with the rotation of the first gear 4, the first protrusion 5 arranged on the top surface thereof is also synchronously rotated; since the first protrusion 5 has a first inclined sliding surface and the second protrusion 6 on the bottom surface of the movable plate 3 has a second inclined sliding surface, in the rotating process, the first inclined sliding surface of the first protrusion 5 is in contact with the second inclined sliding surface, and the movable plate 3 is pushed to slide upward or downward along the guide inclined surface; meanwhile, the cooperation of the limiting plate 22 and the limiting groove 32 effectively limits the horizontal displacement of the movable plate 3, so that the movable plate 3 realizes the reciprocating lifting movement in the vertical direction, and the dynamic visual display effect is formed; the display device of the utility model has the music display effect and the dynamic visual display effect at the same time, greatly enriches the display mode, can more effectively attract the attention of the audience, and highlights the characteristics of the displayed articles. It should be noted that the sound producing assembly in the display device can be a common music movement, which can drive the sound spring through the gear in the driving mechanism to drive the sound cylinder to emit music.

[0055] Specifically, the movable plate 3 comprises a plurality of sub-plates 31 which are spliced with each other, and the bottom surface of each sub-plate 31 is provided with the second protrusion 6 and the limiting groove 32.

[0056] The movable plate 3 is spliced into a heart shape by three sub-plates 31, and the bottom surface of each sub-plate 31 is provided with the second protrusion 6 and the limiting groove 32; since the movable plate 3 is spliced by a plurality of sub-plates 31, if one of the sub-plates 31 is damaged, the entire movable plate 3 does not need to be replaced, and only the damaged sub-plate 31 needs to be separately disassembled and replaced; the shape of the movable plate 3 is a heart shape.

[0057] Specifically, the number of the first protrusions 5 is multiple, and the multiple first protrusions 5 are annularly distributed on the first gear 4.

[0058] The multiple first protrusions 5 are annularly distributed on the first gear 4, and in the rotating process of the first gear 4, the first protrusion 5 and the second protrusion 6 of the movable plate 3 are always in the cooperation state; by adjusting the distribution interval of the first protrusions 5 on the first gear 4, the lifting rhythm and frequency of the movable plate 3 can be changed. When the first protrusions 5 are more densely distributed, the lifting frequency of the movable plate 3 per unit time is increased, and the display rhythm is accelerated; on the contrary, if the distribution is sparse, the lifting rhythm of the movable plate 3 is slowed down, and the display effect tends to be slow.

[0059] When the intervals between the first protrusions 5 are the same, the first inclined sliding surfaces of the first protrusions 5 will simultaneously contact and act on the second inclined sliding surfaces of the corresponding second protrusions 6, so that the three sub-panels 31 are synchronously lifted, creating a neat and uniform display effect; when the intervals between the first protrusions 5 are different, the first inclined sliding surfaces of the first protrusions 5 will contact the second inclined sliding surfaces of the corresponding second protrusions 6 at different time nodes, so that the three sub-panels 31 are lifted in sequence, creating a dynamic display effect with rich levels.

[0060] Specifically, the first inclined sliding surface includes a first support surface 52 and a first inclined surface 51; the top surface of the first protrusion 5 is the first support surface 52, and the side surfaces on both sides of the first support surface 52 are the first inclined surface 51; the second inclined sliding surface includes a second support surface 62 and a second inclined surface 61; the top surface of the second protrusion 6 is the second support surface 62, and the side surfaces on both sides of the second support surface 62 are the second inclined surface 61.

[0061] As the first protrusion 5 rotates, the first inclined surface 51 on one side of the first protrusion 5 gradually contacts the second inclined surface 61 on one side of the second protrusion 6; during the contact, the first inclined surface 51 exerts an upward component force on the movable panel 3, thereby pushing the movable panel 3 to ascend along the first inclined surface 51; when the first protrusion 5 rotates to the point where the first inclined surface 51 completely slides out of the second inclined surface 61, the movable panel 3 reaches the highest position of the ascent, at which time the first support surface 52 contacts the second support surface 62, providing the movable panel 3 with a short and stable horizontal support, so that the movable panel 3 is maintained at the top position of the ascent; as the first protrusion 5 continues to rotate, the first inclined surface 51 on the other side of the first protrusion 5 begins to contact the second inclined surface 61 on the other side of the second protrusion 6; during the contact, the movable panel 3 descends along the first inclined surface 51 under the action of its own gravity and the guidance of the first inclined surface 51, until it completely slides out of the first inclined surface 51, and the movable panel 3 descends to the lowest position; this cycle continues, and multiple first protrusions 5 are annularly distributed on the first gear 4, continuously driving the movable panel 3 to perform the lifting movement.
