DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0024] As shown in Figure 1 and Figure 2 The embodiment of the present application provides a voice coil motor motion platform, which comprises an L-shaped support seat 1 for fixing a voice coil motor 2, two support blocks 11 and two blocking blocks 12 for blocking the voice coil motor 2 are symmetrically arranged on the L-shaped support seat 1, one end of the support block 11 is connected with the vertical end of the L-shaped support seat 1, the other end of the support block 11 is connected with the horizontal end of the L-shaped support seat 1, the blocking block 12 is installed on the horizontal end of the L-shaped support seat 1 and located on one side of the support block 11, the blocking block 12 is arranged opposite to the driving end of the voice coil motor 2, the blocking block 12 is used for blocking the driving end of the voice coil motor 2, and the horizontal end of the L-shaped support seat 1 is provided with a limiting block 13 for limiting the movement direction of the voice coil motor 2.

[0025] The blocking block 12 is provided with a first rubber pad 14 for buffering the voice coil motor 2, and the limiting block 13 is provided with a second rubber pad 15 for buffering the voice coil motor 2.

[0026] Specifically, one end of the voice coil motor 2 is fixedly connected with the vertical end of the L-shaped support seat 1, so that the voice coil motor 2 is located between the two support blocks 11, the driving end of the voice coil motor 2 is connected with the vertical end of the L-shaped fixed seat 21, and the horizontal end of the L-shaped fixed seat 21 is slidably connected with the horizontal end of the L-shaped support seat 1 through the sliding assembly 22. The two ends of the bottom of the vertical end of the L-shaped fixed seat 21 are respectively stop matched with the two blocking blocks 12, and one end of the horizontal end of the L-shaped fixed seat 21 is limit matched with the limiting block 13.

[0027] When the voice coil motor 2 operates, the mover 24 of the voice coil motor 2 drives the coil 25 and the L-shaped fixed seat 21 to move linearly. When the mover 24 of the voice coil motor 2 moves in the movement direction, the limiting block 13 provided with the second rubber pad 15 limits the L-shaped fixed seat 21, so as to limit the movement distance of the mover 24 of the voice coil motor 2, and prevent the phenomenon of excessive movement from occurring. When the mover 24 of the voice coil motor 2 moves towards the cylindrical shell 23 and the permanent magnet 26 of the voice coil motor 2, the blocking block provided with the first rubber pad 14 stops the L-shaped fixed seat 21, so as to stop the movement distance of the mover 24 of the voice coil motor 2, and prevent the phenomenon of the mover 24 from being excessively moved to damage the cylindrical shell 23 and the permanent magnet 26.

[0028] In the above structure, the L-shaped support seat 1 and the two support blocks 11 are arranged to improve the fixing strength and the supporting strength of the voice coil motor 2. The two ends of the L-shaped fixed seat 21 of the voice coil motor 2 are respectively limited by the limiting block 13 provided with the second rubber pad 15 and the two blocking blocks 12 provided with the first rubber pad 14. The first rubber pad 14 and the second rubber pad 15 play a buffering role for the voice coil motor 2, reduce the friction between the voice coil motor 2 and the blocking block 12 and the limiting block 13, and improve the service life of the blocking block 12 and the limiting block 13. The voice coil motor movement platform not only has good support and stability, but also improves the wear resistance and saves the replacement cost.

[0029] As Figure 3 and Figure 4As shown in one embodiment, one end of the voice coil motor 2 of the voice coil motor motion platform is fixedly connected to the vertical end of the L-shaped support base 1. An L-shaped fixing base 21 is provided on the driving end of the voice coil motor 2. The horizontal end of the L-shaped fixing base 21 slides with the horizontal end of the L-shaped support base 1 via a sliding assembly 22. One end of the L-shaped fixing base 21 is provided with a retaining groove 211 for retaining engagement with the retaining block 13. The other end of the L-shaped fixing base 21 is provided with two retaining notches 212 for retaining engagement with two blocking blocks 12. The vertical end of the L-shaped fixing base 21 is connected to the mover 24 of the voice coil motor 2. A slider is provided at the bottom of the horizontal end of the L-shaped fixing base 21. A guide rail is provided at the top of the horizontal end of the L-shaped support base 1. The slider and the guide rail slide together, allowing the L-shaped fixing base 21 to slide with the L-shaped support base 1. One end of the horizontal end of the L-shaped fixing base 21 is provided with a square retaining groove 211, which retains engagement with the retaining block 13. The bottom end of the vertical end of the L-shaped fixing seat 21 is provided with a limiting notch 212, which is engaged with the blocking block 12. The setting of the L-shaped fixing seat 21 not only improves the driving stability of the voice coil motor 2, but also improves the limiting and blocking effects.

[0030] like Figure 3 and Figure 4 As shown, in one embodiment, the L-shaped fixing base 21 of the voice coil motor motion platform is an integrally formed structure. This arrangement improves the support strength and stability of the voice coil motor 2.

[0031] like Figure 5 As shown in one embodiment, the voice coil motor 2 of the voice coil motor motion platform comprises a cylindrical housing 23, a mover 24, and a coil 25. One end of the cylindrical housing 23 is connected to the vertical end of the L-shaped support base 1. A permanent magnet 26 is disposed in the center of the cylindrical housing 23. The coil 25 is wound around the mover 24. The mover 24 is sleeved around the permanent magnet 26 without contacting the permanent magnet 26. A gap is provided between the permanent magnet 26 and the cylindrical housing 23 to allow the mover 24 and coil 25 to move. The end of the mover 24 away from the cylindrical housing 23 is connected to the L-shaped fixed base 21. The mover 24 is a cylindrical structure, and the coil 25 is wound around the mover 24. When the mover 24 extends between the cylindrical housing and the permanent magnet 26, the magnetic field generated by the permanent magnet 26 interacts with the magnetic field generated by the coil 25, causing the mover 24 and coil 25 to move horizontally in a straight line. This arrangement facilitates the mover 24 to drive the L-shaped fixed base 21 for horizontal movement.

[0032] like Figure 1As shown in the drawings, in one of the embodiments, the limiting block 13 of the voice coil motor moving platform is an integral L-shaped structure, and the limiting block 13 and the blocking block 12 are made of steel. The L-shaped limiting block 13 improves the fixing effect of the limiting block 13 and the L-shaped support seat 1. The material improves the limiting strength of the limiting block 13 and the blocking block 12.

[0033] As shown in the drawings, Figure 2 As shown in the drawings, in one of the embodiments, the L-shaped support seat 1 of the voice coil motor moving platform is made of high-strength aluminum alloy. The L-shaped support seat 1 uses high-strength aluminum alloy material, which greatly improves the support force of the voice coil motor 2 and does not need to rely on external equipment for fixing.

[0034] As shown in the drawings, Figure 2 As shown in the drawings, in one of the embodiments, the L-shaped support seat 1 of the voice coil motor moving platform is further provided with a displacement sensor 3 for detecting the moving distance of the voice coil motor 2. The displacement sensor 3 facilitates the detection of the moving distance of the mover 24 of the voice coil motor 2.

[0035] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the application patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the application patent should be subject to the appended claims.
