Description

Technical Field

[0001] This utility model relates to the field of microelectronics, and in particular to a carrier structure for a shake-stabilizing motor, a shake-stabilizing motor, and an electronic device. Background Technology

[0002] A capacitor motor utilizes plates within the motor to form a capacitor. Changes in the signal detected by the capacitor provide feedback on the movement of the lens within the motor. Besides the plates mounted on a flexible circuit board, the remaining plates can be fixed to the motor's carrier structure using sheet metal components. Additionally, sheet metal structures are used to support and connect magnets and other circuitry connected to the circuit board. To minimize space requirements, these sheet metal components are typically embedded within the carrier structure.

[0003] However, the number of sheet metal parts that need to be embedded into the carrier structure is currently quite large. Embedding two or more sheet metal parts into the carrier structure requires more complex mold design or multiple sets of molds, increasing mold costs. Furthermore, the positions of multiple sheet metal parts embedded into the carrier structure require more precise positioning and adjustment, increasing processing costs. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a carrier structure for a shake-stabilizing motor, a shake-stabilizing motor, and an electronic device. By changing the way the sheet metal parts are set in the carrier structure, only one first sheet metal part is set in the side of the first carrier by embedding, and the remaining second sheet metal parts are all installed on the surface of the first carrier. By reducing the complexity of the internal structure of the first carrier, the processing cost of the first carrier is reduced.

[0005] To solve the above-mentioned technical problems, embodiments of this utility model provide a carrier structure for a shake-stabilizing motor, comprising: a first sheet metal part, a first carrier, and a second sheet metal part; the first sheet metal part is one in number and is embedded in the side of the first carrier; a first positioning member is provided on the outer surface of the side of the first carrier; the second sheet metal part includes a second positioning member, which matches the first positioning member to determine the relative position of the second sheet metal part and the outer surface of the side.

A second positioning element on the second sheet metal part matches the first positioning element on the first carrier, thus determining the position of the second sheet metal part on the first carrier. Since only one sheet metal part is embedded in the first carrier, there is no need to consider the positional matching of multiple sheet metal parts during manufacturing, reducing the manufacturing difficulty and cost of the first carrier. Furthermore, the position of the second sheet metal part is determined by the first positioning element on the first carrier and the second positioning element on the second sheet metal part, making the positioning of the second sheet metal part more accurate.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to enable the reader to better understand this utility model. However, the technical solutions claimed by this utility model can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0038] The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this utility model. The various embodiments can be combined with or referenced by each other without contradiction.

[0039] When multiple sheet metal parts are embedded in a carrier structure and positioned on the same plane, if these parts are placed too close together, the molten plastic cannot flow smoothly into and fill the mold cavity during injection molding of the carrier component. This prevents the formation of a plastic structure connecting the two sheet metal parts. Furthermore, the cooling and shrinkage of the molten plastic during injection molding generates stress. If the distance between two sheet metal parts is too close, this stress concentrates in the narrow space, causing the sheet metal parts to be deformed or the plastic to crack. These cracks will result in insufficient signal shielding. Therefore, the positional relationship of multiple sheet metal parts embedded in the carrier component is as follows: Figure 1As shown, gaps 9 need to be provided between multiple sheet metal parts to facilitate the inflow of molten plastic and the release of shrinkage stress. Due to the aforementioned positional requirements for multiple sheet metal parts, when two or more sheet metal parts are embedded in the carrier component, the positioning structure of multiple inserts needs to be considered during mold design and manufacturing. This significantly increases the complexity of the injection mold, and the cost of mold manufacturing and maintenance increases by 30% to 50% compared to embedding a single sheet metal part. Furthermore, due to the thermal expansion and contraction effects of injection molding, the position of the sheet metal parts in the injection-molded carrier component may change. For sheet metal parts with high positional accuracy requirements, the embedding method affects the accuracy of the sheet metal part's function, increasing the processing difficulty and cost.

[0040] Based on the above problems, embodiments of this utility model relate to a carrier structure for a shake-stabilizing motor, such as... Figures 2 to 3 As shown, the carrier structure includes: a first sheet metal part 21, a first carrier 11, and a second sheet metal part 22; the number of the first sheet metal part 21 is one, as shown... Figure 2 As shown, the first sheet metal part 21 is embedded in the side portion 111 of the first carrier 11; a first positioning member 31 is provided on the outer surface of the side portion 111 of the first carrier 11. Figure 3 As shown, the second sheet metal part 22 includes a second positioning member 221, which matches the first positioning member 31 to determine the relative position of the second sheet metal part 22 and the outer surface of the side 111.

[0041] The first positioning element can be a positioning boss, and the corresponding second positioning element is a positioning hole. The contour of the positioning boss matches the contour of the positioning hole. The contour of the positioning hole is designed according to the shape of the second sheet metal part, and the contour of the positioning boss is designed according to the contour of the positioning hole. The second sheet metal part includes: a first sheet metal end face and a second sheet metal end face that are perpendicular to each other; there are multiple positioning holes, at least one of which is located on the first sheet metal end face, and at least one positioning hole is located at the connection between the first sheet metal end face and the second sheet metal end face; there are multiple positioning bosses, at least one of which is located on the side of the first carrier, and at least one positioning hole is located at the connection between the side and the bottom of the first carrier. Figure 3 As shown, the number of second positioning elements 221 (such as positioning holes) is set to four. One square second positioning element 211 is located on the end face of the first sheet metal part, which can also be understood as one square second positioning element 211 being located on the side of the first sheet metal part. The other three second positioning elements 211 are located at the connection between the first and second sheet metal end faces. The outlines of these three second positioning elements 211 are determined by the outline of the electrode plate unit formed by bending in the second sheet metal part. Similarly, under the above arrangement of the second positioning elements 211, as... Figure 2As shown, a first positioning element 31 is provided at a corresponding position of the second positioning element 211. Providing the first positioning element 31 at different positions on the first carrier is more conducive to positioning the second sheet metal part and improves positioning accuracy.

[0042] like Figure 4 As shown, the projections of the first sheet metal part 21 and the second sheet metal part 22 on the cross section (the cross section is a plane parallel to the focusing direction and parallel to the surface of the second sheet metal part) have almost no overlap. Therefore, there is no need to make any structural avoidance design for the first sheet metal part, the second sheet metal part, and the first carrier; it is only necessary to consider the positional relationship between the first sheet metal part and the second sheet metal part.

[0043] Compared to related technologies, this embodiment of the utility model features a carrier structure for the anti-shake motor in which a single first sheet metal part is embedded in the side of a first carrier. The remaining second sheet metal part is positioned based on a first positioning element located on the outer surface of the side of the first carrier. A second positioning element on the second sheet metal part matches the first positioning element on the first carrier, thus determining the position of the second sheet metal part on the first carrier. Since only one sheet metal part is embedded in the first carrier, there is no need to consider the positional matching of multiple sheet metal parts during manufacturing, reducing the manufacturing difficulty and cost of the first carrier. Furthermore, the position of the second sheet metal part is determined by the first positioning element on the first carrier and the second positioning element on the second sheet metal part, making the positioning of the second sheet metal part more accurate.

[0044] The following describes other structures of the carrier structure of the anti-shake motor in the embodiments of this utility model, such as... Figures 5 to 7 As shown, through grooves 4 are provided on the sides and bottom of the first carrier, wherein, Figure 5 The diagram shows the bottom structure of the first carrier, with a through groove 4 set at each end of the bottom surface of the first carrier. Figure 6 The diagram shows a side view of the first carrier. Similarly, a through groove 4 is provided at each end of the side view of the first carrier. Figure 7 The diagram shown is a schematic diagram of the top surface structure of the first carrier. Figure 7 The top surface and Figure 5 The bottom surface is the opposite surface of the first carrier, therefore the positions of the through hole 4 on the top surface and the through hole 4 on the bottom surface are consistent. The outline of the through groove is circular and / or trapezoidal. For example, the outlines of the through holes on the top and bottom surfaces can be set to circular, and the outlines of the through holes on the sides can be set to trapezoidal. Alternatively, the corresponding through hole outlines can be set according to the shapes of the first carrier and the second sheet metal part.

[0045] When assembling the second sheet metal part, the end face of the first sheet metal part covers the through groove 4 on the side, and the end face of the second sheet metal part covers the through groove 4 at the bottom. When the second sheet metal part is assembled onto the first carrier, glue is filled through the through groove 4, such as... Figure 8As shown, the adhesive contacts the first sheet metal part through the through-holes 4. Adhesive filled through the side through-holes 4 contacts the side adhesive filling area 51 of the first sheet metal part, and adhesive filled through the bottom or top through-holes 4 contacts the bottom adhesive filling area 52 of the first sheet metal part. This strengthens the fixing effect between the first carrier and the second sheet metal part. Through-holes on different surfaces can fix the second sheet metal part with adhesive from different directions. Furthermore, the through-holes 4 can reduce the mass of the first carrier, thereby reducing the overall weight of the anti-vibration motor. The dispersed through-holes can reduce deformation caused by stress during injection molding. Additionally, several corresponding through-holes are also provided on the first carrier for guiding, limiting, and demolding guidance purposes.

[0046] The first sheet metal part is a ring-shaped structure that matches the side of the first carrier, providing support for the first carrier. The first sheet metal part can be grounded or connected to the coil circuit. It also serves as signal shielding, reducing interference with the AF direction detection signal. Figure 3 As shown, a plurality of holes 211 are provided on the first sheet metal part. The holes 211 are evenly distributed on the first sheet metal part, which helps to disperse stress and make the stress of the first sheet metal part and the first carrier more uniform, thereby improving the stability of the overall structure. In addition, the plastic melt during injection molding can form a mechanical lock through the holes. The plastic melt fixed in the holes can play a role similar to a rivet, making the combination of the first sheet metal part and the first carrier more secure.

[0047] In addition, the carrier structure of the image stabilization motor also includes: a second carrier and a third sheet metal part embedded in the second carrier; a first carrier surrounds the second carrier, and the first carrier and the second carrier are spaced apart; the projection portion of the third sheet metal part toward the second sheet metal part is located on the second sheet metal part. Figure 9 The diagram shows the structure of the third sheet metal part 23. An AF receiving electrode plate 62 is provided in the third sheet metal part 23, as shown below. Figure 10 As shown, the AF receiving electrode 62 and the AF emitting electrode 61 on the second sheet metal part 62 form a capacitance detection unit in the AF direction (focusing direction). The AF receiving electrode 62 and the AF emitting electrode 61 have a facing area, meaning the projection of the AF receiving electrode 62 towards the second sheet metal part falls on the AF emitting electrode 61. The projected area changes as the AF receiving electrode 62 moves in the AF direction. A first emitting electrode 63 and a second emitting electrode 65 are also provided on the second sheet metal end face of the second sheet metal part 62. The first emitting electrode is positioned opposite to the first receiving electrode, and the second emitting electrode is positioned opposite to the second receiving electrode. These are used to detect the movement distance in the jitter direction, which is divided into the X-axis direction and the Y-axis direction. One of the two pairs of electrodes (first emitting electrode and first receiving electrode, second emitting electrode and second receiving electrode) is used to detect the movement distance in the X-axis direction, and the other pair is used to detect the movement distance in the Y-axis direction.

[0048] An installation space is reserved in the first carrier for the position of the AF emitter plate 61 to facilitate the positioning and assembly of the AF emitter plate 61.

[0049] Another feasible embodiment of this utility model relates to a shake-stabilizing motor, including the carrier structure of the shake-stabilizing motor described above, and an electrode unit disposed opposite to a second sheet metal part of the carrier structure. The electrode unit and the second sheet metal part constitute a capacitor detection structure, which is used to detect the movement distance of the carrier structure.

[0050] like Figure 11 As shown, the electrode unit is disposed on the flexible circuit board, and the electrode unit includes at least: a first receiving electrode 64 and a second receiving electrode 66. Figure 12 As shown, a differential electrode structure is formed by one emitter electrode corresponding to two receiver electrodes. For example, one first emitter electrode 63 corresponds to two first receiver electrodes 64, and one second emitter electrode 65 corresponds to two second receiver electrodes 66.

[0051] In addition, the image stabilization motor also includes: a suspension wire and a spring, the spring being mounted on, for example... Figure 2 On the spring-loaded protrusion shown, the second carrier moves relative to the first carrier in the AF direction via the spring. In addition, the anti-shake motor includes a magnet, which works with the coil to drive the first and second carriers. The first or second sheet metal part can also be used to position the magnet.

[0052] Another feasible embodiment of this utility model relates to an electronic device, including: the carrier structure of the above-mentioned anti-shake motor, or the above-mentioned anti-shake motor.
