DETAILED DESCRIPTION

[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0037] A speaker flip structure for maintaining sound effects, such as Figure 1-3 As shown, the lifting mechanism is mainly composed of connecting rods, and each connecting rod rotates around its own axle pin to drive the disc to rotate and rise. The following is a detailed description:

[0038] The speaker flip structure includes:

[0039] The disc comprises a flip cover plate 8 and a support rod 2, wherein the flip cover plate 8 is arranged on one side of the top end of the support rod 2;

[0040] The connecting rod group includes: a main driving connecting rod 7, a first connecting rod 1, a second connecting rod 3, a third connecting rod 4 and a fourth connecting rod 6. The main driving connecting rod 7 is connected to the driving motor through a gear shaft 71. The bottom end of the first connecting rod 1 is connected to the bottom end of the main driving connecting rod 7. The main driving connecting rod 7 can drive the first connecting rod 1 to perform circular motion under the drive of the driving motor. The upper ends of the first connecting rod 1 and the second connecting rod 3 are rotatably connected to the support rod 2 through a movable rotating pin shaft 21. The bottom end of the second connecting rod 3 is connected to the housing 9. The first connecting rod 1 is provided with a first driving pin 12 and a second driving pin 13. The driven end 41 of the third connecting rod 4 is connected to the second driving pin 13, and the driving end is connected to the bottom end of the support rod 2. The driven end of the fourth connecting rod 6 is connected to the first driving pin 12, and the driving end is connected to the support rod 2 through a movable rotating pin shaft 21.

[0041] Furthermore, it also includes: a ugliness-concealing cover plate 5, which is connected to the fourth connecting rod 6 via a movable rotating pin 21, and the fourth connecting rod 6 drives the ugliness-concealing cover plate 5 to move via the movable rotating pin 21.

[0042] Furthermore, the main driving connecting rod 7 includes a main driving connecting rod, a gear shaft 71 is arranged on the outer side of the upper end of the main driving connecting rod, and a driving groove 72 is opened at the bottom end of the main driving connecting rod 7. A first connecting rod rotating shaft center 11 is arranged at the top end of the first connecting rod 1, and the first connecting rod 1 is rotatably connected with the movable rotating pin shaft 21 through the first connecting rod rotating shaft center 11. A follower pin 14 is arranged on the side of the bottom end of the first connecting rod 1, and the follower pin 14 cooperates with the driving groove 72. When the driving motor is powered on in the closed state, the main driving connecting rod 7 rotates clockwise with the gear shaft 71 as the center, and the driving groove 72 drives the follower pin 14 in the groove to move together, thereby driving the first connecting rod 1 to make a circular motion with the first connecting rod rotating shaft center 11 as the center.

[0043] Further, the first driving pin 12 is arranged at the middle part of the first connecting rod 1. When the first connecting rod 1 rotates, the first driving pin 12 can drive the fourth connecting rod 6 to move together. The driving end of the fourth connecting rod 6 is connected to the flip cover plate 8 through a movable rotating pin shaft 21. When the driven end of the fourth connecting rod 6 moves under the drive of the first connecting rod 1, the driving end of the fourth connecting rod 6 can further drive the flip cover plate 8 to move through the movable rotating pin shaft 21. The second driving pin 13 is located at the bottom of the first connecting rod 1. When the first connecting rod 1 rotates, the second driving pin 13 can drive the third connecting rod 4 to move together. The driving end of the third connecting rod 4 is connected to the pin shaft at the bottom end of the support rod 2. When the driven end of the third connecting rod 4 moves under the drive of the first connecting rod 1, the driving end of the third connecting rod 4 can further drive the support rod 2 to move through the pin shaft.

[0044] Furthermore, the cover plate 5 is located above the fourth connecting rod 6, and the movement trajectory of the cover plate 5 is a circular arc movement centered on the axle pin of the second connecting rod 3. The cover plate 5 is provided with a cover plate axle pin 51, and when the flip cover plate 8 is opened or closed, the cover plate axle pin 51 moves along the track groove 91 of the housing 9.

[0045] The connection and working process of the flip structure of this application:

[0046] like Figure 4 In order to match the main driving link 7 with the first connecting rod 1, the driving motor (not shown) is connected to the main driving link 7 through the gear shaft 71. When the motor is powered on and running in the closed state, the main driving link 7 rotates clockwise around the gear shaft 71. When the main driving link 7 rotates clockwise, the driving groove 72 on the main driving link 7 drives the driven pin 14 on the first connecting rod 1 in the groove to move together, thereby driving the first connecting rod 1 to make an arc motion with the center of the first connecting rod shaft 11 as the center.

[0047] like Figure 5-Figure 6As shown, when the first connecting rod 1 rotates clockwise with its own first connecting rod rotating shaft center 11, the first driving pin 12 also rotates around the first connecting rod rotating shaft center 11 of the first connecting rod 1 at the same time. Since the driven end 61 of the fourth connecting rod is connected to the first driving pin 12, the first driving pin 12 will drive the fourth connecting rod 6 to move together. The other end of the fourth connecting rod 6 is connected to the flip cover plate 8 through a movable rotating shaft pin 21, so the fourth connecting rod 6 will drive the support rod 2 to move through the movable rotating shaft pin 21. At the same time, the support rod 2 is connected to the second connecting rod 3 and the fourth connecting rod 6 through the movable rotating shaft pin 21 (one shaft pin passes through three parts). The second connecting rod pin shaft 31 of the second connecting rod 3 is fixed on the hole of the housing 9 of the flip mechanism, so the movable rotating shaft pin 21 can only perform arc motion with the second connecting rod pin shaft 31 of the second connecting rod 3 as the center.

[0048] like Figure 7 As shown, when the first connecting rod 1 rotates clockwise around its own rotation axis center, the second driving pin 13 also rotates around the rotation axis center of the first connecting rod 1 at the same time. Since the driven end 41 of the third connecting rod is connected to the second driving pin 13 of the first connecting rod 1, the second driving pin 13 will drive the third connecting rod 4 to move together. The driving end of the third connecting rod 4 is connected to the end shaft pin of the support rod 2, so the third connecting rod 4 will drive the disc to perform an arc motion with the movable rotating shaft pin 21 as the center. Therefore, two arc motions of the flip cover 8 are realized: one is an arc motion centered on the movable rotating shaft pin 21, and the other is an arc motion centered on the shaft pin of the second connecting rod 3. The two motions are finally combined into the motion path of the flip cover 8.

[0049] like Figure 8 As shown, the ugliness-concealing cover 5 is connected to the fourth connecting rod 6 through a movable rotating shaft pin 21. When the fourth connecting rod 6 moves, the fourth connecting rod 6 will drive the ugliness-concealing cover 5 to move through the movable rotating shaft pin 21. The motion trajectory is a circular arc motion centered on the shaft pin of the second connecting rod 3; the ugliness-concealing cover pin 51 of the ugliness-concealing cover 5 moves along the track groove of the shell 9 of the lifting mechanism.

[0050] Although the present invention has been disclosed as above by the embodiments, it is not intended to limit the present invention. Any person skilled in the art may make various choices and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is limited by the claims and their equivalents.
