Description

Technical Field

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

[0002] In the development of VCM motors, as mobile devices such as smartphones increasingly demand higher image quality from their cameras, higher performance requirements are also being placed on VCM motors. Traditional spring-loaded conventional motors typically employ a single-step design, integrating spring assembly and preload function onto the same step. While this design can meet basic requirements to some extent, it has many drawbacks.

[0003] Due to the need for spring preload, the depth of the recessed platform is relatively large. This not only occupies a significant amount of internal space in the motor but also severely restricts the design space for the spring. As a key component affecting motor performance, the limited design space of the spring directly hinders further performance improvements and fails to meet the growing market demand. Under the limitations of existing technology, developing a new VCM motor design that optimizes space utilization and improves spring performance is particularly important.

[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 an end cap 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] This utility model provides an end cap structure, including: a housing, the housing having a first step for supporting spring assembly, the first step being arranged in a circular array on the side of the housing, and the first step having symmetrically arranged recessed platforms on the side, and a second step for overall installation and pre-compression being formed between adjacent recessed platforms, and the horizontal height of the second step being lower than that of the first step.

[0009] Furthermore, the sinking platform consists of eight groups, and the eight groups of sinking platforms are arranged in a circular array on the side of the shell.

[0010] Furthermore, the second step consists of four groups, and the four groups of the second step are arranged in a circular array at the end of the housing.

[0011] Furthermore, the first step and the second step are located on the top surface of the shell and are horizontal.

[0012] Furthermore, the housing is provided with an adjustment groove.

[0013] on the other hand:

[0014] This utility model also provides a VCM motor, including the end cap structure described above.

[0015] The beneficial effects of this utility model are:

[0016] 1. This invention optimizes space utilization. Traditional spring-loaded motors have a large recessed platform due to spring preload, occupying a significant amount of internal space. This invention separates the spring assembly and preload function into two distinct steps. The depths of the first and second steps can be independently designed according to the actual needs of their respective functions. The recessed platform depth of the first step can be precisely designed based on the spring dimensions, without excessively deepening it to accommodate the preload function; the depth of the second step can be optimized according to the actual preload requirements. This effectively reduces the space occupied by the recessed platform, providing more space for the layout of other internal components of the motor and promoting the miniaturization of the motor design.

[0017] 2. This invention improves spring performance. In traditional designs, the large depth of the recessed platform limits the spring's design space, preventing it from fully realizing its potential. This invention optimizes the step design, providing a more reasonable design space for the spring. When the spring is installed on the first step, the precise design of the recessed platform depth allows the spring to expand better, and its elastic potential energy can be utilized more effectively. Simultaneously, the independent second step handles pre-compression, avoiding interference with spring installation and performance during the pre-compression process. This allows the spring to operate in a more stable environment, significantly improving spring performance and consequently enhancing the overall motor performance.

[0018] 3. This invention improves assembly precision and stability. The multiple countersunk edges of the first step, distributed along the various sides of the housing, allow for more precise spring positioning compared to a traditional single-step design, reducing spring deviation during installation. The second step, positioned at the four corners of the housing end, ensures more uniform preload during installation, further enhancing motor stability during operation. This high-precision assembly and stable operation contribute to improved motor reliability and lifespan.

[0019] In summary, this utility model effectively solves the problems of traditional VCM motors through its innovative end cap structure design, and has significant advantages in optimizing space utilization, improving spring performance, enhancing assembly precision and stability, and improving the shooting experience.

[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.

[0027] 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.

[0028] According to an embodiment of the present invention, an end cap structure and a VCM motor are provided.

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

[0030] An end cap structure includes: a housing 1, the housing 1 having a first step 2 for supporting spring assembly, the first steps 2 being arranged in a circular array on the side of the housing 1, and the first steps 2 having symmetrically arranged recessed platforms 21 on the side, and a second step 3 for overall installation pre-compression being formed between adjacent recessed platforms 21, and the horizontal height of the second step 3 being lower than that of the first step 2. The housing 1 also includes an adjustment groove 4.

[0031] Using the aforementioned technical solution, the first step 2 primarily functions as the spring assembler, providing a precise installation position for the spring and ensuring its stability during operation. The second step 3 is responsible for overall installation preloading, optimizing motor performance through reasonable preloading settings. This functional separation design allows each step to focus on its specific function, avoiding the mutual interference problems caused by functional integration in traditional designs.

[0032] In the actual assembly process, the spring is first installed on the first step 2, and the recessed platform 21 on the side of the first step 2 is used for precise positioning to ensure the accuracy and stability of the spring installation. Since the depth of the recessed platform 21 is precisely designed according to the spring dimensions, the spring can better extend and fully utilize its elastic performance. Then, the entire assembly is pre-loaded via the second step 3. The lower height design of the second step 3 makes the pre-loading process more reasonable, avoiding adverse effects on spring installation and performance. The adjustment groove 4 can be used for fine-tuning of internal components during installation or debugging, further improving the product's performance and reliability.

[0033] Specifically, traditional leaf spring motors suffer from a large recessed area in the housing due to spring preload, occupying a significant amount of internal space. This technology separates the spring assembly and preload function into two distinct steps, allowing the depths of the first step 2 and the second step 3 to be independently designed according to their respective functional requirements. The recessed area 21 of the first step 2 can be precisely designed based on the spring dimensions, without excessively deepening it to accommodate the preload function; the depth of the second step 3 can be optimized according to the actual preload requirements. This effectively reduces the space occupied by the recessed area, providing more space for the layout of other internal components and facilitating the miniaturization of the motor.

[0034] Furthermore, in traditional designs, the large depth of the recessed platform limits the design space for the spring, preventing it from fully realizing its performance potential. This technology, however, optimizes the step design, providing a more reasonable design space for the spring. When the spring is installed on the first step 2, the precise design of the recessed platform 21 allows the spring to expand better, enabling more effective utilization of its elastic potential energy. Simultaneously, the independent second step 3 handles pre-compression, avoiding interference with spring installation and performance during the pre-compression process. This allows the spring to operate in a more stable environment, significantly improving its performance and consequently enhancing the overall motor performance.

[0035] In addition, there are eight sets of sinking platforms 21, and the eight sets of sinking platforms 21 are arranged in a circular array on the side of the shell 1. Among them, there are four sets of second steps 3, and the four sets of second steps 3 are arranged in a circular array at the end of the shell 1. The first step 2 and the second step 3 are located on the top surface of the shell 1 and are horizontal.

[0036] In this technical solution, the multiple countersunk edges 21 of the first step 2 are distributed on various sides of the housing 1, providing multiple positioning points for spring installation. Compared with the traditional single-step design, this allows for more precise spring positioning and reduces spring deviation during installation. Furthermore, the placement of the second step 3 at the four corners of the housing 1 ensures more uniform preload during installation, further improving the motor's stability during operation. This high-precision assembly and stable operating condition contribute to improved motor reliability and service life.

[0037] Example 2

For example, in mobile phone shooting scenarios, cameras equipped with this VCM motor can focus quickly and accurately, delivering clear, high-quality images to users whether shooting static scenes or moving images, greatly improving the user's shooting experience.

[0041] In summary, the following effects can be achieved by utilizing the above-described technical solution of this utility model:

[0042] This invention effectively solves the problems of traditional VCM motors through innovative end cap structure design, and has significant advantages in optimizing space utilization, improving spring performance, enhancing assembly accuracy and stability, and improving shooting experience.
