DETAILED DESCRIPTION

[0056] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0057] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0058] Reference Figure 1-12 The piezoelectric image pickup drive device of this embodiment will be described.

[0059] The driving device includes a base 1 , a sliding assembly, a lens carrier 2 , a piezoelectric driving assembly, a positioning assembly and a circuit board 10 .

[0060] A lens carrier 2 is movably arranged in the base 1 along the front-back direction; it also includes a first lens and a second lens, the first lens and the second lens are arranged along the optical axis direction, wherein the first lens is fixedly arranged at one end of the base 1, and the second lens is arranged on the lens carrier 2.

[0061] In one embodiment, anti-collision rubber pads are provided on the front and rear sides of the lens carrier 2, and the anti-collision rubber pads are embedded in the lens carrier 2. Part of the structure of the anti-collision rubber pads protrudes from the lens carrier 2. When the lens carrier 2 drives the second lens to move and zoom along the front and rear directions, it plays an anti-collision and buffering role between the base 1, and the anti-collision rubber pads can also be replaced with other flexible materials.

[0062] The sliding assembly is arranged on the base 1 along the front-back direction; the lens carrier 2 is mounted on the sliding assembly and moves relative to the base 1 along the front-back direction through the sliding assembly;

[0063] The piezoelectric drive assembly includes a drive rod 4 and a piezoelectric vibrator arranged at the end of the drive rod 4. The drive rod 4 is connected to the lens carrier 2. The positioning assembly is sleeved on the drive rod 4, and the piezoelectric vibrator drives the drive rod 4 to drive the lens carrier 2 to move in the front and back directions.

[0064] The circuit board 10 is electrically connected to the piezoelectric vibrator through the metal strip 9. Specifically, the metal strip 9 is embedded in the bottom of the base 1, and the circuit board 10 provides an electrical signal to the piezoelectric ceramic through the metal strip 9. The other end of the circuit board 10 forms a PIN pin for external electrical signal connection.

[0065] The piezoelectric vibrator consists of an elastic body, a piezoelectric ceramic, and a connection plate. The elastic body is arched in side projection, with a concave and convex portion. The convex portion is connected to the piezoelectric rod drive rod 4, the piezoelectric ceramic is connected to one side of the elastic body's concave portion, and the connection plate is connected to the piezoelectric ceramic. When energized, the piezoelectric ceramic deforms, causing the elastic body to move horizontally, thereby driving the piezoelectric rod drive rod 4 and the lens carrier 2 to move.

[0066] An electronic component 11 is provided on the circuit board 10, and a second magnet 12 is provided on the side wall of the lens carrier 2. Some of the electronic components 11 are correspondingly provided with the second magnet 12, wherein one electronic component 11 is a sensor, and the sensor is correspondingly provided with the second magnet 12 for detecting and feedback of the zoom displacement of the lens carrier 2.

[0067] A protective structure is provided on the outside of the circuit board 10. This structure includes a reinforcement plate and a metal plate. The reinforcement plate, which conforms to the shape of the circuit board 10, is positioned outside the circuit board 10 to enhance its structural strength. The metal plate, preferably a steel plate, is secured to the outside of the reinforcement plate, enclosing the reinforcement plate and circuit board 10. This shields against magnetic interference and enhances the stability of the piezoelectric camera drive during operation.

[0068] In one embodiment, the positioning assembly includes a fixed clamp 5 and a stabilizing assembly. The fixed clamp 5 is mounted on the drive rod 4 and fixedly connected to the lens carrier 2. The stabilizing assembly includes a first stabilizing member and a second stabilizing member 7. When the drive rod 4 moves in the forward and backward directions, it passes through the first stabilizing member and / or the second stabilizing member 7.

[0069] The fixing clamp 5 and the stabilizing assembly are spaced apart along the axial direction of the driving rod 4 .

[0070] The first stabilizing member is a stabilizing clamp 3, which is clamped to the driving rod 4. The stabilizing clamp 3 includes a first fixing plate 31 and a first bent portion 32. The first bent portion 32 is formed on the first fixing plate 31 and includes a first upper clamping piece 321 and a first lower clamping piece 322 that are bent and arranged opposite each other. A triangular guide slot is formed between the first upper clamping piece 321 and the first lower clamping piece 322 for the driving rod 4 to pass through and exit.

[0071] The first upper clamping piece 321 and the first lower clamping piece 322 are provided with first expansion pieces 324 along the edges of the drive rod 4's insertion and exit directions. The first expansion pieces 324 are curled outward to form a first curved surface 323. The first expansion pieces 324 are provided on the first upper clamping piece 321 and the first lower clamping piece 322. The provision of the first expansion pieces 324 facilitates the insertion of the piezoelectric drive rod 4 between the first upper clamping piece 321 and the first lower clamping piece 322, facilitating installation of the piezoelectric drive rod 4.

[0072] In one embodiment, the first upper clamping piece 321 and the first lower clamping piece 322 are arranged in parallel.

[0073] In another embodiment, the cross-section of the first upper clamping piece 321 is a curved arc surface, preferably a V-shape. The cross-section of the first lower clamping piece 322 is a plane. It should be explained in detail that when the drive rod 4 is located in the triangular guide bin, the first upper clamping piece 321 is V-shaped and the first lower clamping piece 322 is a plane. Therefore, the drive rod 4 is clamped by the two inner side walls of the V-shape of the first upper clamping piece 321 and the inner side wall of the plane of the first lower clamping piece 322, forming a three-sided clamping.

[0074] The stabilizing clamp 3 is made of a flexible material, specifically rubber, and is clamped to the end of the piezoelectric drive rod 4, specifically the end away from the piezoelectric vibrator. This stabilizing clamp 3 stabilizes the piezoelectric drive rod 4, improving the stability of the piezoelectric camera drive device during zooming.

[0075] The second stabilizing member 7 is a rubber ring, positioned away from the first stabilizing member and close to the piezoelectric vibrator. A through-hole is defined in the center for the drive rod 4 to pass through. A snap-fitting portion is provided on the outside of the second stabilizing member 7, securing the second stabilizing member 7 to the base 1 via the snap-fitting portion. The second stabilizing member 7 and the stabilizing clamp 3 are positioned at each end of the piezoelectric drive rod 4, working together to stabilize the piezoelectric drive rod 4 and improve the stability of the piezoelectric camera drive device during zooming.

[0076] The fixing clamp 5 is clamped at the middle of the piezoelectric rod driving rod 4 and includes a second fixing plate 51 and a second bending portion 52 .

[0077] The second bent portion 52 is formed on the second fixing plate 51. The second bent portion 52 includes a second upper clamping piece 521 and a second lower clamping piece 522 that are arranged opposite to each other after the second bent portion 52 is bent. A triangular clamping cavity is formed between the second upper clamping piece 521 and the second lower clamping piece 522 for the driving rod 4 to move forward and backward.

[0078] The second upper clamping piece 521 and the second lower clamping piece 522 are provided with second expansion pieces 524 along the edges of the clamping direction of the drive rod 4. The second expansion pieces 524 are curled outward to form a second curved surface 523. The second expansion pieces 524 are provided on the second upper clamping piece 521 and the second lower clamping piece 522. The provision of the second expansion pieces 524 facilitates the insertion of the piezoelectric rod drive rod 4 into the clamping cavity, facilitating the installation of the piezoelectric rod drive rod 4. In this embodiment, the piezoelectric rod drive rod 4 is secured within the clamping cavity by the second upper clamping piece 521 and the second lower clamping piece 522.

[0079] It should be noted that the second upper clamping piece 521 and the second lower clamping piece 522 are arranged in parallel; and the cross section of the second upper clamping piece 521 is a curved arc surface or V-shaped, preferably V-shaped. The cross section of the second lower clamping piece 522 is a plane or V-shaped, preferably a plane. It should be explained in detail that when the driving rod 4 is located in the triangular clamping cavity, the second upper clamping piece 521 is V-shaped and the second lower clamping piece 522 is a plane. Therefore, the driving rod 4 is clamped by the two inner side walls of the V-shaped second upper clamping piece 521 and the inner side wall of the plane of the second lower clamping piece 522, forming a three-sided clamping.

[0080] The sliding assembly is provided between the lens carrier 2 and the base 1, so that the lens carrier 2 can move in the base 1 along the front-back direction. Figure 1 As shown, the side of the lens carrier 2 where the piezoelectric drive assembly is located is defined as the left side, and the side where the circuit board 10 is located is defined as the right side. The sliding assembly can be implemented in various ways, such as a sliding member and an adsorbing member. The sliding member includes a sliding shaft or a ball member 13, wherein the sliding shaft can be one or two. When there is one sliding shaft, the sliding shaft is the first sliding shaft 8, which is disposed on the right side of the lens carrier 2. When there are two sliding shafts, the sliding shafts are the second sliding shaft 16 and the first sliding shaft 8, respectively disposed on the left and right sides of the lens carrier 2. The ball member 13 is a ball bearing and is located on the right side of the lens carrier 2. The adsorbing member is a magnet that is adsorbed to the sliding shaft or base 1 to improve the stability of the overall structure.

[0081] The specific possible combinations are:

[0082] In one embodiment, sliding shafts (a first sliding shaft 8 and a second sliding shaft 16) are provided on both the left and right sides of the base 1 for use with the sliding grooves provided on the lens carrier 2, and a first magnet 6 is provided on the side of the lens carrier 2 facing the base 1, and the first magnet 6 is respectively attracted to the sliding shafts. Alternatively, in another embodiment, the sliding shaft may be provided only on the right side of the base.

[0083] Alternatively, in one embodiment, the right sliding shaft is provided through the lens carrier 2, and the magnet is only attached to the second sliding shaft 16, or in another embodiment, no magnet may be provided.

[0084] Or in one embodiment, a sliding shaft (first sliding shaft 8) is only provided on the right side of the lens carrier 2, and the sliding shaft (first sliding shaft 8) is passed through the lens carrier 2; in another embodiment, a magnet may be provided on the side of the lens carrier 2 facing the base 1, and the magnet is adsorbed on the base 1.

[0085] In one embodiment, the sliding shaft on the right side of the above embodiment can be eliminated and replaced with a ball member 13. In this embodiment, a specific example of the sliding assembly is described.

[0086] Sliding component example 1, such as Figure 2 and Figure 7 As shown, it includes: a first sliding shaft 8 and a second sliding shaft 16 arranged in parallel and spaced apart on the base 1; a sliding groove is formed on both sides of the bottom of the lens carrier 2, and the sliding groove is mounted on the first sliding shaft 8 and the second sliding shaft 16; a first magnet 6 is fixedly set on both sides of the lens carrier 2, and is indirectly adsorbed with the first sliding shaft 8 and the second sliding shaft 16 respectively and has a magnetic adsorption force. The first magnet 6 can provide pre-pressure for the lens carrier 2, thereby enhancing the stability of the lens carrier 2 when it moves relative to the sliding shaft.

[0087] The chute includes a V-shaped groove and a U-shaped groove, and grooves 15 are provided on the inner wall surfaces of the V-shaped groove and the U-shaped groove.

[0088] It should be noted that the width of the U-shaped groove is greater than the width of the sliding shaft. The V-shaped groove can better guide the sliding, while the U-shaped groove can be used for tolerance. The setting of the U-shaped groove can allow the lens carrier 2 and the like to have a certain production error, ensuring that when the size of the lens carrier 2 is slightly larger or smaller due to production errors, the lens carrier 2 can be successfully installed on the sliding shaft. By setting the U-shaped groove, the fault tolerance rate can be improved, which is beneficial to saving production costs. In addition, by setting the groove 15 on the inner wall surface of the V-shaped groove and the U-shaped groove, the contact area between the sliding shaft and the V-shaped groove and the U-shaped groove can be reduced, and the friction between the sliding shaft and the lens carrier 2 can be reduced. In addition, the groove 15 is a filling cavity that can be filled with a substance, and the filling cavity can be used to fill grease to further reduce the friction between the sliding shaft and the lens carrier 2.

[0089] Sliding component example 2, such as Figure 8 As shown, it includes: a first sliding shaft 8, which is arranged on the base 1 along the front-to-back direction, and the first sliding shaft 8 and the piezoelectric drive component are respectively located on both sides of the lens carrier 2; a through groove 17 is provided on the side of the lens carrier 2, and the first sliding shaft 8 is arranged through the through groove 17.

[0090] The through groove 17 is a C-shaped groove, which can limit the first sliding shaft 8 in two directions in the vertical direction, and can achieve smooth operation of the overall structure without the need for a magnet to generate a downward adsorption force; wherein, the inner wall surface of the C-shaped groove is provided with a groove 15, which is a filling cavity that can be filled with a substance, and the filling cavity can be used to fill grease to further reduce the friction between the sliding shaft and the lens carrier 2.

[0091] Sliding component example three, such as Figure 9-11 As shown, it includes: a first half slide groove 18, which is arranged on the inner bottom surface of the base 1 along the front-to-back direction; a second half slide groove 19, which is arranged on the side of the lens carrier 2 facing the base 1; a ball component 13, which is arranged between the first half slide groove 18 and the second half slide groove 19, and the lens carrier 2 moves along the front-to-back direction through the ball component 13.

[0092] Sliding component example 4, such as Figure 9 As shown, it includes: a third magnet 14 , which is arranged on the side of the lens carrier 2 facing the base 1 , and the third magnet 14 is indirectly adsorbed on the base 1 .

[0093] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
