Description

Technical Field

[0001] This utility model relates to the field of VCM motor technology, specifically to a spring structure and a VCM motor. Background Technology

[0002] Traditional VCM motors typically employ a two-part design with ±2 poles in the lower contact spring, which only meets the basic positive and negative conduction requirements. When the motor needs to achieve multi-channel signal transmission, complex current control, or integrate multiple functional modules, the two-part contact spring structure cannot provide sufficient conductive partitions, resulting in limited circuit design and making it difficult to meet the electrical performance requirements of new application scenarios such as high-pixel cameras and multi-camera modules.

[0003] In addition, in conventional VCM motors, the terminals and lower springs are often connected separately, such as by welding or crimping. This connection method suffers from unstable contact resistance and insufficient connection strength, making it prone to malfunctions such as poor contact and terminal detachment during long-term operation or vibration. Furthermore, the separate connection requires additional assembly steps, increasing production complexity and cost.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, the purpose of this utility model is to propose a spring sheet structure and a VCM motor to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] on the one hand:

[0008] A spring-loaded structure includes: a base, and a spring-loaded substrate embedded in the base, the spring-loaded substrate being connected to a plurality of terminals, the plurality of terminals being embedded in the base, and adjacent terminals being separated by an insulating gap.

[0009] Furthermore, the spring substrate and the terminal are integrally molded.

[0010] Furthermore, the terminals are formed into exposed connection parts through a bending process.

[0011] Furthermore, the bending angle of the connecting part is 90°±5°, and the bending radius is 0.1-0.3mm.

[0012] Furthermore, a slot for the adapter connector is provided on one side of the base.

[0013] Furthermore, there are at least six sets of terminals, and the six sets of terminals are snapped into the slots by the connecting parts.

[0014] Furthermore, the width of the insulation gap is 0.1-0.15 mm.

[0015] on the other hand:

[0016] A VCM motor includes the aforementioned spring structure.

[0017] The beneficial effects of this utility model are:

[0018] This invention optimizes the connection method between the spring substrate and the terminal, reducing the space occupied inside the motor, improving structural reliability, enhancing connection strength and conductivity stability, and simplifying the production process to meet the design requirements of miniaturization and high reliability of mobile terminals.

[0019] Meanwhile, the multi-zone terminal design with insulation gap separation solves the problem of the single conductive function of the traditional two-part spring contact, realizing multi-channel independent conductivity and meeting the needs of complex circuit control.

[0020] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0027] According to an embodiment of the present invention, a spring-loaded structure is provided.

[0028] Example 1

[0029] like Figure 1 As shown, Embodiment 1 of the present invention is as follows:

[0030] A spring sheet structure includes: a base 1 and a spring sheet substrate 2 embedded in the base 1. The spring sheet substrate 2 is connected to a plurality of terminals 3, which are embedded in the base 1 and adjacent terminals 3 are separated by an insulating gap.

[0031] The spring substrate 2 and the terminal 3 are integrally formed. The terminal 3 is formed into an exposed connecting part 4 by a bending process. The bending angle of the connecting part 4 is 90°±5°, and the bending radius is 0.1-0.3mm.

[0032] In this technical solution, the material of the spring substrate 2 can be high-elasticity stainless steel or copper alloy, with a thickness of 0.05-0.2mm. It is formed into a multi-segment structure through a stamping process, with rounded corners at the edges of each segment to reduce stress concentration. At the same time, the spring substrate 2 has a rectangular or irregular shape as a whole, with positioning holes on the edges to facilitate precise assembly with the base 1.

[0033] In addition, terminal 3 can be made of copper alloy material, such as C17200 beryllium bronze, with a thickness of 0.1-0.3mm, and is integrally connected to the spring substrate 2 by injection molding. At the same time, the exposed part of terminal 3 is formed into an L-shaped or U-shaped connection part 4 by bending process, with a bending angle of 90°±5° and a bending radius of 0.1-0.3mm, which facilitates external circuit soldering.

[0034] The base 1 has a slot 5 on one side for the adapter connector 4. There are at least six sets of terminals 3, and all six sets of terminals 3 are engaged in the slot 5 via the connector 4. The width of the insulation gap is 0.1-0.15 mm.

[0035] This technical solution, through a multi-terminal 3 design, can simultaneously realize the independent transmission of multiple channels such as drive current, feedback signal, and auxiliary functions. Compared with the traditional two-part spring contact, the circuit design flexibility is greatly improved, making it suitable for complex scenarios such as dual OIS optical image stabilization and multi-camera collaborative control.

[0036] Example 2

[0037] Embodiment 2 of the present invention is as follows:

[0038] A VCM motor includes the aforementioned spring structure.

[0039] In this technical solution, the spring substrate 2 is fixed on the base 1, and each section is connected to the electrodes of the base 1 by conductive adhesive or welding. The integrally formed part of the terminal 3 is embedded inside the spring substrate 2, and the exposed bent part of the connection portion 4 extends to the outside of the motor to form an external electrical interface.

[0040] In summary, the above-mentioned technical solution of this utility model achieves the following effects: by optimizing the connection method between the spring substrate and the terminal, the internal space occupied by the motor is reduced, structural reliability is improved, connection strength and conductivity stability are enhanced, and the production process is simplified, adapting to the design requirements of miniaturization and high reliability of mobile terminals. Furthermore, the multi-zoned terminal design with insulation gap separation solves the problem of the traditional two-part spring having a single conductive function, enabling multi-channel independent conductivity and meeting the needs of complex circuit control.
