Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor carrier with a turbulence groove structure. Background Technology

[0002] One component in the structure of a VCM voice coil motor is the "carrier," which connects to the lens barrel. The inner ring of the carrier is made of threads and mates with the lens barrel through these threads. The outer ring is generally a groove designed for winding. Current mobile phones are pursuing an ultra-thin design, so the carrier's thickness is also relatively thin. Existing technology typically uses a circular carrier structure, forming a weld line at the final weld point during injection molding. Due to the decreasing temperature of the injection molding material, a noticeable weld line forms at this final weld point, making it relatively weak and prone to cracking. The gate location for most plastic products is in a fixed area, so the final weld point is also usually fixed. At the weld point, the product's performance requirements cannot be met, and the internal material is uneven during injection molding. Common technical adjustments involve increasing the mold temperature and the material's melting temperature to improve the weld line strength. However, this easily leads to flash defects; the higher the temperature, the larger the flash. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a motor carrier with a turbulence groove structure. By setting multiple grooves on the side of the motor carrier, a turbulence effect is achieved, the position of the weld line is controlled, the internal material of the product is made uniform, and the product performance is improved and the strength is increased without increasing the material temperature.

[0004] Specifically, this utility model discloses a motor carrier with a turbulence groove structure, comprising: a carrier body, wherein a through hole with internal threads is provided in the middle of the carrier body; coil grooves are provided around the sides of the carrier body, wherein multiple turbulence grooves are provided in the coil grooves, and the turbulence grooves have gradually enlarging openings; multiple anti-collision platforms are provided on the upper surface of the carrier body, and positioning posts are provided on the sides of the anti-collision platforms.

[0005] The advantage of adopting the above technical solution is that by setting a turbulence groove in the coil groove, a turbulence effect is played during the injection molding process, which increases the material flow speed and makes the weld line formation position located in a position with greater strength, thereby improving the overall strength of the product.

[0006] Furthermore, the coil groove has a polygonal cross-section with multiple sides, and the number of the turbulence grooves is four, including a first turbulence groove, a second turbulence groove, a third turbulence groove, and a fourth turbulence groove. The first turbulence groove and the second turbulence groove are arranged on the same side, the third turbulence groove is symmetrically arranged with the second turbulence groove, and the fourth turbulence groove is located on the side of the first turbulence groove.

[0007] The advantage of adopting the above technical solution is that by setting four turbulence channels at different positions, the melt can be made to fill the mold cavity more evenly during the injection molding process, reducing the generation of dead flow corners and bubbles, thereby improving the quality and consistency of injection molded products.

[0008] Furthermore, the cross-sectional shape of the turbulence channel is trapezoidal, the opening length of the turbulence channel is 0.3-0.5mm, and the bottom length is 0.1-0.25mm.

[0009] The advantage of adopting the above technical solution is that by refining the structure of the entire turbulence channel, its turbulence effect is made more obvious, thus ensuring the strength of the product.

[0010] Furthermore, the upper surface of the carrier body is provided with multiple dispensing holes.

[0011] The advantages of adopting the above technical solution are that the dispensing hole is used for dispensing adhesive, which facilitates the installation of the spring pieces on both sides after dispensing, and plays a supporting and stable role. At the same time, the dispensing installation connection is tight and extends the service life.

[0012] Furthermore, multiple winding posts are provided on both sides of the coil slot, and the winding posts are provided with blocking surfaces.

[0013] The advantage of adopting the above technical solution is that the setting of the winding post plays the role of supporting the coil, so that the coil will not move in the coil slot, no additional fixing method is required, and it is convenient for installation.

[0014] Furthermore, the carrier body has multiple protrusions on its side.

[0015] The advantage of adopting the above technical solution is that the boss collidees with the motor housing, which plays a good protective role and prevents internal damage.

[0016] Furthermore, the included angle formed by the two sides of the turbulence channel is 90 degrees.

[0017] Furthermore, the anti-collision platform protrudes entirely from the main body of the carrier, with a flat top.

[0018] The advantage of adopting the above technical solution is that during use, the carrier will move up and down and collide with the base of the motor. By setting up a collision protection platform, it can play a role in buffering and protection, ensuring that the internal lens is not damaged.

[0019] Furthermore, the carrier body has an outwardly protruding corner, and the processed weld line is formed at the corner position, located between the second turbulence groove and the third turbulence groove.

[0020] The advantage of adopting the above technical solution is that by setting multiple turbulence grooves, the position of the fusion line is located at the corner where the strength and thickness are greater, which ensures the strength of the entire product, guarantees product quality, and improves service life.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] like Figure 1-2As shown, this utility model discloses a motor carrier with a turbulence groove structure, including: a carrier body 1, the carrier body 1 having a through hole with internal threads in the middle; coil grooves 2 being provided around the sides of the carrier body 1, the coil grooves 2 having multiple turbulence grooves 3 having gradually enlarging openings; and multiple anti-collision platforms 13 being provided on the upper surface of the carrier body 1, the anti-collision platforms 13 having positioning posts 14 on their sides.

[0031] The advantage of adopting the above technical solution is that by setting the turbulence groove 3 in the coil groove 2, it plays a turbulence role during the injection molding process, increases the material flow speed, and makes the weld line 16 form in a position with greater strength, thereby improving the strength of the entire product.

[0032] In some implementations, the cross-section of coil slot 2 is polygonal (e.g., Figure 3-4 As shown, the mold has multiple sides and four flow channels 3, including a first flow channel 31, a second flow channel 32, a third flow channel 33, and a fourth flow channel 34. The first flow channel 31 and the second flow channel 32 are located on the same side, the third flow channel 33 is symmetrically arranged with the second flow channel 32, and the fourth flow channel 34 is located on the side of the first flow channel 31. By setting four flow channels 3 at different positions, during the injection molding process, the melt can be made to fill the mold cavity more evenly, reducing the generation of dead flow zones and air bubbles, thereby improving the quality and consistency of the injection molded product. Furthermore, the specific position and size of the flow channels 3 can be set according to the shape of the product.

[0033] Furthermore, the cross-sectional shape of the turbulence channel 3 is trapezoidal, the opening length of the turbulence channel 3 is 0.3-0.5mm (as shown by symbol a in the figure), the bottom length is 0.1-0.25mm (as shown by symbol b in the figure), and the width of the turbulence channel 3 is between 0.3-0.6mm.

[0034] Furthermore, the included angle formed by the two sides of the turbulence channel 3 is 90 degrees.

[0035] In some implementations, the upper surface of the carrier body 1 is provided with multiple dispensing holes 11, and the sides of the dispensing holes 11 are provided with interconnected arc-shaped grooves. During dispensing and fixing, excess glue will enter the arc-shaped grooves on the sides to prevent excess glue from overflowing, while also ensuring a firm adhesive bond and facilitating the installation of the spring clips on both sides. The lower surface is provided with multiple dispensing grooves 17.

[0036] In some implementations, multiple winding posts 21 are provided on both sides of the coil slot 2. The winding posts 21 are provided with a blocking surface, which is on the same plane as the side of the coil slot 2. The winding posts 21 serve to support the coil, so that the coil will not move in the coil slot 2, and no additional fixing method is required, which facilitates installation.

[0037] Furthermore, the carrier body 1 has multiple protrusions 12 on its side, which are located on both sides of the coil groove 2 and can be changed according to usage requirements. The protrusions 12 collide with the motor housing, providing good protection and preventing internal damage.

[0038] Furthermore, the included angle formed by the two sides of the turbulence groove 3 is 90 degrees.

[0039] In some implementations, the anti-collision platform 13 protrudes entirely from the carrier body 1, with a flat top. The anti-collision platform 13 is positioned on both the upper and lower surfaces of the carrier body 1, protruding symmetrically and with rounded corners. During use, the carrier moves up and down, colliding with the motor base and housing surface. The anti-collision platform 13 provides cushioning and protection, ensuring the internal lens is not damaged.

[0040] Furthermore, the carrier body 1 has an outwardly protruding corner 15, and the processed weld line 16 is formed at the corner 15, located between the second turbulence groove 32 and the third turbulence groove 33.

[0041] The advantage of adopting the above technical solution is that by setting multiple turbulence grooves 3, the position of the fusion line 16 is located at the corner 15 where the strength and thickness are both greater, thus ensuring the strength of the entire product, ensuring product quality, and improving service life.

[0042] During injection molding, an eight-cavity mold can be used. The overall structure and working principle of the mold are the same as existing technologies. Only appropriate bosses need to be set in the injection cavity and corresponding to the turbulence channel to complete the processing. At the same time, Mold Flow tests can be carried out during the trial processing stage to verify the location of the weld line.

[0043] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
