Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0031] The applicant discovered through analysis of existing technology that conventional music boxes open by flipping a lid, and the interior of the outer box also has a certain depth. When the user opens the music box, the decoration inside cannot be directly observed, and the display effect of the music box is not perfect. Therefore, it is necessary to design a music box that can automatically raise the internal structure after the packaging box is opened.
[0032] Reference Figures 1-2 This application illustrates an automatic lifting music box, which includes an outer box, a rotating wheel assembly, and an inner box 10.
[0033] The outer box has an accommodating space for accommodating the rotating wheel assembly and the inner box 10;
[0034] The rotating wheel assembly includes an eccentric wheel 21, a base 22, a drive device 212, and a first contact 222 and a second contact 223 for stopping the rotation of the drive device 212; the base 22 is provided with a step 221, the first contact 222 is disposed on the side surface of the step 221, and the second contact 223 is disposed on the upper surface of the step 221; the drive device 212 is fixedly disposed on the base 22 and drives the eccentric wheel 21 to rotate;
[0035] When the eccentric wheel 21 rotates to the first position, the inner box 10 is lifted by the eccentric wheel 21, and the eccentric wheel 21 triggers the first contact point 222;
[0036] When the eccentric wheel 21 rotates to the second position, the eccentric wheel 21 triggers the second contact 223.
[0037] In the embodiments of this application, addressing the problem that the internal structure of a music box cannot be fully displayed in the prior art, this application provides a solution where the internal structure of a music box can be lifted and lowered by an eccentric wheel 21. Specifically, the automatic lifting music box includes an outer box, a rotating wheel assembly, and an inner box 10; the outer box has an accommodating space for accommodating the rotating wheel assembly and the inner box 10; the rotating wheel assembly includes an eccentric wheel 21, a base 22, a driving device 212, and a first contact 222 and a second contact 223 for stopping the rotation of the driving device 212; the base 22 has a step 221, and the first contact 222 is disposed on the step 221. On the side surface, the second contact 223 is disposed on the upper surface of the step 221; the driving device 212 is fixedly disposed on the base 22 and drives the eccentric wheel 21 to rotate; when the eccentric wheel 21 rotates to the first position, the inner box 10 is lifted by the eccentric wheel 21, and the eccentric wheel 21 triggers the first contact 222; when the eccentric wheel 21 rotates to the second position, the eccentric wheel 21 triggers the second contact 223. This application provides a rotatable eccentric wheel 21 in the accommodating space and controls the eccentric wheel 21 to stop through two contacts. By controlling the rotation angle of the eccentric wheel 21, the technical effect of lifting and lowering the inner box 10 is achieved.
[0038] The following will further describe an automatic lifting music box in this exemplary embodiment.
[0039] In an embodiment of this application, the automatic lifting music box includes an outer box, a rotating wheel assembly, and an inner box 10;
[0040] The outer box has an accommodating space for accommodating the rotating wheel assembly and the inner box 10;
[0041] The rotating wheel assembly includes an eccentric wheel 21, a base 22, a drive device 212, and a first contact 222 and a second contact 223 for stopping the rotation of the drive device 212; the base 22 is provided with a step 221, the first contact 222 is disposed on the side surface of the step 221, and the second contact 223 is disposed on the upper surface of the step 221; the drive device 212 is fixedly disposed on the base 22 and drives the eccentric wheel 21 to rotate;
[0042] When the eccentric wheel 21 rotates to the first position, the inner box 10 is lifted by the eccentric wheel 21, and the eccentric wheel 21 triggers the first contact point 222;
[0043] When the eccentric wheel 21 rotates to the second position, the eccentric wheel 21 triggers the second contact 223.
[0044] It should be noted that the eccentric wheel 21 refers to a wheel whose rotation point is not in the center position. This application only needs to ensure that when the eccentric wheel 21 rotates to the first position, the side of the eccentric wheel 21 with the longer diameter abuts between the bottom of the inner box 10 and the accommodating space to support the inner box 10.
[0045] When the inner box 10 is lowered, the shorter side of the eccentric wheel 21 is positioned between the inner box 10 and the accommodating space to achieve the technical effect of automatically raising and lowering the inner box 10.
[0046] Since the music box needs to maintain the inner box 10 when it is opened, the eccentric wheel 21 needs to stop rotating when it reaches the desired position. The base 22 of this application is provided with a step 221, and contacts for controlling the eccentric wheel 21 to stop rotating are respectively provided on different surfaces of the step 221. When the eccentric wheel 21 rotates to the first position, it will touch the first contact 222 on the side surface of the step 221 and stop rotating. When the music box is closed, the eccentric wheel 21 rotates to the second position and touches the second contact 223 on the upper surface of the step 221 and stops rotating.
[0047] In an embodiment of this application, the automatic lifting music box further includes a motherboard for controlling the start and stop of the drive device 212;
[0048] The motherboard is disposed within the accommodating space, and the motherboard is electrically connected to the driving device 212, the first contact 222 and the second contact 223 respectively.
[0049] It should be noted that the drive device 212 described in this application is used to control the forward and reverse rotation of the drive device 212; the main board can also be electrically connected to other devices inside the music box that require power and control, such as light strips, rotatable accessories, etc., and control the operation of these devices through the main board.
[0050] In an embodiment of this application, the automatic lifting music box further includes an outer cover;
[0051] The outer cover is movably connected to the outer box, and the outer cover is provided with a third contact for triggering the rotation of the drive device 212. The third contact is electrically connected to the motherboard.
[0052] When the outer cover is opened, the third contact is triggered, and the motherboard controls the drive device 212 to rotate in the forward direction;
[0053] When the outer cover is closed, the third contact is triggered, and the motherboard controls the drive device 212 to rotate in the reverse direction.
[0054] It should be noted that, since the step 221 is provided in this application, and the eccentric wheel 21 will contact the upper surface and side surface of the step 221, the eccentric wheel 21 cannot rotate 360° to return to its original position. Therefore, after the eccentric wheel 21 rotates to the first position, it needs to rotate in the opposite direction to the second position.
[0055] In an embodiment of this application, the base 22 further includes two parallel mounting plates 213; the mounting plates 213 are disposed on the upper surface of the step 221;
[0056] The driving device 212 includes a body and a driving end. The body is fixedly mounted on the mounting plate 213, and the eccentric wheel 21 is disposed between the mounting plates 213 and fixedly connected to the driving end.
[0057] It should be noted that the mounting plate 213 is disposed on the upper surface of the step 221 near the edge of the side surface, so that when the eccentric wheel 21 rotates to the first position, it can touch the first contact point 222 of the side surface. In order to ensure the stability of the eccentric wheel 21 when it rotates to the first position, it is necessary to ensure the stability of the driving device 212. By fixing the body of the driving device 212 to the mounting plate 213, the stability of the driving device 212 can be guaranteed.
[0058] In an embodiment of this application, the eccentric wheel 21 includes a connecting rod and a plurality of eccentric wheel pieces 21 of the same shape; wherein, the eccentric wheel pieces 21 are elliptical in shape.
[0059] The eccentric wheels 21 are arranged side by side on the connecting rod. One end of the connecting rod is fixedly connected to the driving end, and the other end of the connecting rod is rotatably connected to the mounting plate 213.
[0060] It should be noted that the eccentric wheels 21 arranged side by side increase the contact area between the eccentric wheels 21 and the inner box 10, ensuring the stability of the inner box 10; the eccentric wheels 21 can be elliptical or egg-shaped to ensure that the eccentric wheels 21 can smoothly raise and lower the inner box 10.
[0061] In an embodiment of this application, the eccentric wheel 21 is provided with an extension hook on the side near the connecting rod for touching the first contact point 222.
[0062] It should be noted that the extension hook is used to ensure that the first contact 222 is triggered when the eccentric wheel 21 rotates to the first position.
[0063] In an embodiment of this application, the automatic lifting music box further includes a power supply, which is electrically connected to the motherboard.
[0064] It should be noted that the power supply provides power to the drive device 212 and other internal components of the music box.
[0065] In an embodiment of this application, the angle between the first position and the second position is 90°.
[0066] It should be noted that the angle of the step 221 is also 90°; when the angles of the first position and the second position change, the angle of the step 221 also needs to change accordingly.
[0067] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
[0068] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.
