Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4 This application provides further details.

[0023] This application discloses a flip-type speaker structure.

[0024] Example 1

[0025] Reference Figure 1 and Figure 2 The flip-type loudspeaker structure includes a base 100, with several reinforcing ribs fixedly connected to the bottom surface of the base 100. By adding these reinforcing ribs to the base 100, its bending and torsional resistance and load-bearing capacity can be effectively improved, enhancing its overall strength and rigidity. A support unit 200 is rotatably connected to the base 100, and the loudspeaker 400 is mounted on the support unit 200. A drive unit 300 is provided on the base 100 to drive the support unit 200 to rotate. The support unit 200 has threaded holes, and a mounting bolt matching the size of the threaded hole passes through the loudspeaker 400. One end of the mounting bolt facing the threaded hole is threaded into the threaded hole. Operators can remove the loudspeaker 400 from the support unit 200 by removing the bolts, enabling the loudspeaker 400 to be detachably connected and easily replaced or repaired later.

[0026] Therefore, starting the drive unit 300 drives the support unit 200 to rotate, thereby causing the speaker 400 on the support unit 200 to move synchronously, realizing the angle adjustment of the speaker 400 relative to the base 100. This provides greater flexibility and makes it easier to adjust the direction and position of the speaker 400 to obtain a better sound experience, meeting the different needs of different users for the car speaker 400.

[0027] Reference Figure 1 and Figure 2The support unit 200 includes a support plate 210 rotatably connected to the base 100. In this embodiment, the support plate 210 and the base 100 can be made of self-lubricating engineering plastic, which is inexpensive and can effectively reduce noise risk. The drive unit 300 includes a connecting seat 310 hinged to the base 100, and a lead screw motor 320 is mounted on the connecting seat 310. In this embodiment, a linear lead screw motor 320 is specifically used. The linear lead screw motor 320 has a more compact structure, uses fewer parts, and is inexpensive. By controlling the linear lead screw motor 320, stepless adjustment can be achieved, and complex integrated movements can be completed while hovering at any angle. The lead screw motor 320 can also be implemented as a separate mechanism using a brushless motor connected to a worm gear or gear reduction mechanism, depending on the actual situation.

[0028] Reference Figure 1 and Figure 2 The outer edge of the lead screw at the output end of the lead screw motor 320 is threadedly connected to a lead screw nut 330. The end of the support unit 200 facing the lead screw nut 330 is rotatably connected to the lead screw nut 330. In this embodiment, the distance between the hinge point of the connecting seat 310 and the base 100, the hinge point of the support plate 210 and the lead screw nut 330, and the hinge point between the support plate 210 and the base 100 can be adjusted according to the actual interior space of the vehicle.

[0029] Therefore, starting the lead screw motor 320 drives the lead screw at the output end of the lead screw motor 320 to rotate. The rotation of the lead screw motor 320 drives the lead screw nut 330 to move along the lead screw direction. The lead screw nut 330 drives the support plate 210 to move synchronously. Since one end of the support plate 210 is hinged to the lead screw nut 330 and the other end is hinged to the base 100, the angle of the speaker 400 relative to the base 100 can be adjusted. This provides greater flexibility and makes it easier to adjust the direction and position of the speaker 400 to obtain a better sound experience, meeting the different needs of different users for the car speaker 400.

[0030] Reference Figure 1 and Figure 2The base 100 has a rotating hole 220, and a rotating column 230 matching the size of the rotating hole 220 is fixedly connected to the support plate 210. The rotating column 230 is rotatably connected inside the rotating hole 220. An opening groove 221 is provided on the wall of the rotating hole 220. In this embodiment, the opening of the opening groove 221 is chamfered to reduce the possibility of the sharp edge of the opening groove 221 scratching the rotating column 230. A guide flat 231 for easy installation is provided on the rotating column 230. Therefore, by setting the rotating hole 220 as an opening and fitting the guide flat 231 with the opening groove 221, the operator can easily insert the rotating column 230 into the rotating hole 220, improving the flexibility and convenience of installing the support plate 210, ensuring strength while facilitating quick assembly.

[0031] Reference Figure 1 and Figure 2 A first limiting block 240 is fixedly connected to the support unit 200. A limiting groove 110 is formed on the surface of the base 100 facing the speaker 400. Two first buffer pads 120 are installed opposite each other on the groove wall of the limiting groove 110. The two first buffer pads 120 are vertically aligned on the same straight line. The first limiting block 240 is located between the two first buffer pads 120. In this embodiment, the first buffer pads 120 can be made of rubber. Therefore, when the support plate 210 moves and drives the first limiting block 240 to move, the first buffer pads 120 play a shock-absorbing and buffering role between the first limiting block 240 and the base 100, reducing the impact force of the first limiting block 240 on the base 100. At the same time, the first buffer pads 120 can absorb the noise generated when the first limiting block 240 contacts the first buffer pads 120.

[0032] The implementation principle of this application embodiment is as follows: Start the lead screw motor 320, which drives the lead screw at the output end of the lead screw motor 320 to rotate. The rotation of the lead screw of the lead screw motor 320 drives the lead screw nut 330 to move along the lead screw direction. The lead screw nut 330 drives the support plate 210 to move synchronously. Since one end of the support plate 210 is hinged to the lead screw nut 330 and the other end is hinged to the base 100, the angle adjustment of the speaker 400 relative to the base 100 can be realized. This provides greater flexibility and facilitates the adjustment of the direction and position of the speaker 400 to obtain a better sound experience, meeting the different needs of different users for the vehicle speaker 400.

[0033] Example 2

[0034] Reference Figure 3 and Figure 4The difference between Embodiment 2 and Embodiment 1 is that a plurality of connecting plates 170 are fixedly connected to the base 100. The connecting plates 170 are evenly distributed around the base 100, and each of the connecting plates 170 has a connecting hole 171, which facilitates the connection of the base 100 to vehicle components. A limit frame 130 is bolted to the base 100. In this embodiment, the limit frame 130 is located at the center of the length direction of the base 100. A second limit block 140 is fixedly connected to the support unit 200. The second limit block 140 is located between the limit frame 130 and the base 100. A second buffer pad 150 is installed on the surface of the second limit block 140 facing away from the base 100, and a third buffer pad 160 is installed on the surface of the base 100 facing the second limit block 140. In this embodiment, the second buffer pad 150 and the third buffer pad 160 can be made of rubber material.

[0035] Therefore, when the support plate 210 moves the second limiting block 140 during the movement, the second buffer pad 150 plays a buffering role between the second limiting block 140 and the limiting frame 130, and the third buffer pad 160 plays a shock absorption role between the second limiting block 140 and the base 100, reducing the impact of the second limiting block 140 on the base 100 and the limiting frame 130 while absorbing the impact noise caused by the impact.

[0036] Example 3

[0037] Reference Figure 1 The difference between Embodiment 3 and Embodiment 1 is that the drive unit 300 includes a connecting block rotatably connected to the base 100, and an electric push rod is mounted on the connecting block. Specifically, a small electric push rod can be used in this embodiment. A hinge block is mounted on the output end of the electric push rod, and the end of the support plate 210 facing the hinge block is hinged to the hinge block. Therefore, when the electric push rod is activated, the hinge block at the output end of the electric push rod extends and retracts. Since one end of the support plate 210 is hinged to the hinge block and the other end is hinged to the base 100, the angle of the speaker 400 relative to the base 100 can be adjusted. This provides greater flexibility and facilitates adjustment of the speaker 400's direction and position to obtain a better sound experience, meeting the different needs of different users for the vehicle speaker 400.
