[0002] Existing camera motor guide structures are complex and difficult to assemble, which not only increases production costs but also reduces production efficiency. Furthermore, due to their structural complexity, these motors are often bulky, limiting their application in products aiming for a slim and lightweight design. Therefore, to meet market demands for cost-effectiveness and portability, simplifying guide structures, reducing assembly difficulty and costs to improve product quality and achieve slimmer, lighter products has become an urgent need for industry development. Utility Model Content

[0003] In view of this, the present invention provides an ultra-miniature focusing motor, which adopts an integrated guide component design, simplifies the production process, shortens the time to market, improves product quality and yield, and reduces weight and size, thus meeting the market demand for lightweight and thinner designs.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An ultra-miniaturized focusing motor includes a base, a housing connected to the base, a carrier for supporting a lens, a coil and a magnet for driving the carrier to move. The base is provided with guide members that guide the movement direction of the carrier and make point or line contact with the carrier. The guide members are integrally formed with the base, and there are two guide members. If the guide member makes point contact with the carrier, one of the two guide members has single-point contact with the carrier, and the other of the two guide members has multi-point contact with the carrier. If the guide member makes line contact with the carrier, one of the two guide members has single-line contact with the carrier, and the other of the two guide members has multi-line contact with the carrier.

[0006] By designing the guide and the base as an integrated structure, several technical innovations are achieved. It simplifies the assembly process of the independent guide in traditional motors, significantly reduces the assembly time and the need for special tools, thereby shortening the product launch cycle. Integrated design reduces potential errors caused by part assembly, improves the overall quality and yield of the product, and effectively saves costs. At the same time, the integrated design ensures the high-precision positioning of the guide, reduces friction and deviation, and improves the guide performance and response speed of the motor, which has a positive impact on image quality and user experience. In addition, the one-piece molding technology reduces weight and size, meets the market demand for lightness and thinness, enhances the overall strength and durability, improves the impact and vibration resistance, and prolongs the service life of the motor. During daily use or transportation, the integrated guide can better resist external forces and ensure stable operation of the motor in various environments. The automated mass production capability of the manufacturing process helps to unify and standardize product quality, reduces the defect rate, and provides a solid quality guarantee for mass production. These advantages not only improve the technical content of the product, but also enhance the market competitiveness of the product, especially in the field of portable electronic devices with high requirements for lightness, thinness and high performance.

[0007] Through single-point and multi-point contact or single-line and multi-line contact, the guide structure is simplified, reducing the space occupation, making the entire motor smaller and more compact, and achieving ultra-small design. Multi-point or multi-line contact provides multiple support points, enhancing the stability of the guide, reducing the deviation that may occur due to a single contact point, and improving the accuracy of focusing. Multi-point or multi-line contact also disperses the contact stress between the carrier and the guide, reducing wear and tear, thereby prolonging the service life of the motor. The design of multi-point or multi-line contact also provides better vibration resistance, allowing the motor to maintain stable performance when subjected to external impact.

[0008] Preferably, the guide is a protrusion in the shape of a cylinder, and the side of the carrier is provided with a guide multi-sided groove for multi-line contact with one of the two guides and a guide single-sided groove for single-line contact with the other guide.

[0009] One guide is in multi-line contact with the guide multi-sided groove, and the other guide is in single-line contact with the guide single-sided groove, providing stable guide control and ensuring stable movement of the carrier during focusing. The guide multi-sided groove and the guide are in multi-line contact, increasing the contact area and enhancing the stability of the structure, which is crucial for maintaining accurate focusing of the lens under various use conditions. The guide single-sided groove and the guide are in single-line contact, reducing the size of the guide structure and effectively utilizing the limited space inside the motor, especially suitable for small devices with limited space, such as smartphone cameras. By optimizing space utilization, ultra-small devices can be achieved without sacrificing performance.

[0010] Preferably, one of the two guides is composed of multiple protrusions, and the other of the two guides has only one protrusion, and the side of the carrier is provided with a guide multi-surface groove in multi-point contact with the multiple protrusions and a guide single-surface groove in single-point contact with the one protrusion.

[0011] One guide has multiple protrusions and is in multi-point contact with the guide multi-surface groove, and the other guide has only one protrusion and is in single-point contact with the guide single-surface groove, providing stable guiding control and ensuring stable movement of the carrier during focusing. The guide multi-surface groove is in multi-point contact with the guide, increasing the number of contact points and thus enhancing the stability of the structure, which is crucial for maintaining accurate focusing of the lens under various use conditions. The guide single-surface groove is in single-point contact with the guide, reducing the volume of the guiding structure and effectively utilizing the limited space inside the motor, which is particularly suitable for small devices with limited space, such as smartphone cameras. By optimizing space utilization, the device can be miniaturized without sacrificing performance.

[0012] Preferably, the guides are grooves with a cylindrical shape, and the side of the carrier is provided with multiple protrusions in multi-point contact with one of the two guides and one protrusion in single-point contact with the other of the two guides.

[0013] One groove-shaped guide is in multi-point contact with multiple protrusions, and the other groove-shaped guide is in single-point contact with one protrusion, providing stable guiding control and ensuring stable movement of the carrier during focusing. The guide is in multi-point contact with multiple protrusions, increasing the number of contact points and thus enhancing the stability of the structure, which is crucial for maintaining accurate focusing of the lens under various use conditions. The guide is in single-point contact with one protrusion, reducing the volume of the guiding structure and effectively utilizing the limited space inside the motor, which is particularly suitable for small devices with limited space, such as smartphone cameras. By optimizing space utilization, the device can be miniaturized without sacrificing performance.

[0014] Preferably, the number of coils is one, and the number of magnets is one.

[0015] The configuration of a single coil and a single magnet greatly compresses the height of the motor without affecting performance, and at the same time, the width is also limitedly compressed, achieving unprecedented miniaturization. This is undoubtedly a boon for electronic products that pursue ultra-thin and ultra-light design trends today, especially in limited space applications.

[0016] Preferably, the guides and the base are made of plastic.

[0017] Compared with metal, plastic is light, effectively reducing the overall weight of the motor, in line with the trend of thin and light electronic products, especially suitable for mobile phone camera modules, can contribute to the lightness of the terminal device.

[0018] Preferably, the two guides are perpendicular to the base.

[0019] The two guides provide sufficient point support to ensure that the carrier remains stable during Z-axis movement, reducing shaking, and symmetrical distribution further enhances the sense of balance, improving movement accuracy and reliability.

[0020] Preferably, the coil is mounted on the circuit board, and the chip and capacitor are also mounted on the circuit board, the coil, chip and capacitor are arranged side by side on the same side of the circuit board, and the other side of the circuit board is provided with a metal reinforcing plate.

[0021] Arranging the coil, chip and capacitor side by side on the same side of the circuit board can further compress the height of the motor, achieving the miniaturization of the motor. The design of adding a metal reinforcing plate on the other side of the circuit board effectively enhances the mechanical strength and impact resistance of the entire structure. The addition of metal material not only provides necessary physical protection to avoid damage to the circuit caused by external pressure or vibration, but also serves as a heat dissipation medium to help remove heat generated by internal components, maintaining the stable operation of electronic devices in high temperature environments.

[0022] Preferably, the magnet is mounted on the carrier.

[0023] The separate design of the magnet and electronic components helps to prevent the magnetic field from adversely affecting adjacent electrical components, such as reducing magnetic coupling effects, thereby improving the safety and reliability of the overall circuit.

The coil 400, chip, and capacitor are arranged side by side on the same side of the FPCB board, and the other side of the FPCB board is provided with a metal reinforcing plate.

[0081] The coil 400, the chip and the capacitor are arranged side by side on the same surface of the FPCB board, so that the height of the motor is further compressed, and the motor is miniaturized. The design of adding the metal reinforcing plate on the other surface of the FPCB board effectively enhances the mechanical strength and the impact resistance of the whole structure. The addition of the metal material not only provides necessary physical protection and avoids circuit damage caused by external pressure or vibration, but also serves as a heat dissipation medium to help remove heat generated by internal components and maintain stable operation of the electronic device in a high-temperature environment.

[0082] In the embodiment, the magnet 500 is mounted on the carrier 300.

[0083] The separated design of the magnet 500 and the electronic components helps to prevent the magnetic field from adversely affecting adjacent electrical components, such as reducing the magnetic coupling effect, thereby improving the safety and reliability of the overall circuit.

[0084] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
