DETAILED DESCRIPTION

[0026] The utility model will be further described below with reference to the drawings.

[0027] Please refer to Figures 1 to 7 The utility model discloses a slide shaft type VCM motor structure, which comprises a base 1 provided with a mounting cavity 11, a carrier 2 movably mounted in the mounting cavity 11, a shell 3 buckled on the base 1 and blocking the carrier 2, a lens 4 mounted on the carrier 2 and passing through the mounting cavity 11 to extend out of the shell 3, and a one-sided magnetic group 5 connected to one of the outer side walls of the carrier 2 and arranged on the base 1 corresponding to a coil group 6 arranged on the base 1 in a one-sided magnetic resistance mode. The shell 3 and the base 1 are mutually buckled to play a fixed supporting role. The carrier 2 is used for rotating into the lens 4. The one-sided magnetic group 5 is used for generating a fixed magnetic field. The one-sided magnetic group 5 cooperates with the coil group 6 to generate a magnetic field loop, so that the carrier 2 moves along the Z direction, and the focusing of the lens 4 is realized.

[0028] In the embodiment, the base 1 is cuboid-shaped structure with length, width and height, the length of the length and the width are approximately or the same, and the base 1 is approximately square. With the height of the base 1 as the Z direction as the reference, the direction of the length of the base 1 is arranged as the X direction, the width direction of the base 1 is matched to the Y direction, and the two sides of the base 1 along the Z direction are arranged as the top surface and the bottom surface of the base 1. The mounting cavity 11 is formed on the base 1 from the top surface along the Z direction, and the shape of the mounting cavity 11 is similar to the shape of the base 1 to be cuboid-shaped. The mounting cavity 11 penetrates the base 1 along the Z direction. When the structure of the utility model is applied in the camera, the light is emitted from the top surface side of the base 1 to the bottom surface side of the base 1 along the Z direction. The side of the mounting cavity 11 opening towards the top surface side is defined as the open side 111, and the carrier 2 is mounted in the mounting cavity 11 from the open side 111. The shell 3 is mounted on the base 1 from the open side 111 side and blocks the open side 111 to prevent the carrier 2 from separating from the open side 111. In order to prevent the carrier 2 from separating from the mounting cavity 11, the boss 112 is formed inwardly protruding on the side of the mounting cavity 11 away from the open side 111 along the Z direction, that is, on the side of the mounting cavity 11 towards the bottom surface and along the edge of the inner wall of the mounting cavity 11. The boss 112 is a square frame-shaped structure as a whole and has four side frames. The four side frames are collectively arranged to form a hole passage 113 on the inside along the Z direction to communicate the mounting cavity 11 and the outside of the base 1. The length and the width of the hole passage 113 are smaller than the length and the width of the carrier 2, so that the carrier 2 can be supported on the boss 112, and the boss 112 can block the carrier 2 to prevent the carrier 2 from separating from the mounting cavity 11 on the bottom surface of the base 1. Since the entire base 1 is small, especially when the utility model is applied in the field of mobile phone cameras, in order to ensure the quality of the boss 112, the reinforcing rib 114 is embedded in the boss 112. In order to facilitate the adjustment of the position of the reinforcing rib 114 in the boss 112 and ensure that the reinforcing rib 114 plays a better role in increasing the strength, the thimble hole 115 is formed on each side frame of the boss 112 and communicates along the Z direction. The thimble hole 115 intersects the cavity in which the reinforcing rib 114 is located in the boss 112, so that the reinforcing rib 114 is adjusted by using a needle-shaped object to pick up the reinforcing rib 114, thereby adjusting the position of the reinforcing rib 114. In order to reduce the wear between the carrier 2 and the boss 112, the end table 116 is formed protruding towards the open side 111 at the four corners of the boss 112. The height of the end table 116 is slightly higher than the height of the other parts of the boss 112, so that when the carrier 2 moves along the Z direction towards the hole passage 113 side, the carrier 2 contacts the end table 116 to play a lower limiting role on the carrier 2. The thimble hole 115 is located on the boss 112 outside the end table 116. In the embodiment, the end table 116 can be made of elastic materials such as silica gel, which can reduce the risk of motor impact and debris while limiting the lower position. Correspondingly, the entire boss 112 is made of elastic material, and the reinforcing rib 114 needs to be arranged to ensure the elastic support of the end table 116 on the carrier 2.Since the whole slide shaft type VCM motor structure is in the electronic device assembly, the part module of the electronic device may need to extend into the mounting cavity 11 from the hole channel 113. Therefore, the avoidance groove 117 is opened at the corresponding module position of the boss 112 according to the need, which is communicated along the Z direction and communicated to the side of the hole channel 113. While avoiding the module, the material is reduced, and the cost is saved to a certain extent.

[0029] In the embodiment, the shape of the carrier 2 is similar to the shape of the mounting cavity 11, which is a cuboid structure, and the length and width of the carrier 2 are slightly smaller than the length and width of the mounting cavity 11, so that the carrier 2 is placed in the mounting cavity 11, and the height of the carrier 2 is smaller than the depth of the mounting cavity 11, so that the carrier 2 can move relative to the mounting cavity 11 along the Z direction. The carrier 2 also has a top surface and a bottom surface in the Z direction, respectively, and the assembly hole 21 is opened through the top surface and the bottom surface of the carrier 2 in the Z direction, and the lens 4 is assembled in the assembly hole 21, so that the carrier 2 carries the lens 4 and moves with the carrier 2 when the single-sided magnetic group 5 cooperates with the coil group 6. The lens 4 is used for focusing and distance adjustment. Among them, the assembly hole 21 is located at the center position of the carrier 2, and the slot 22 is recessed at the four corners of the top surface and the bottom surface of the carrier 2, so as to save material and prevent the carrier 2 from deforming.

[0030] In the embodiment, the carrier 2 has four outer side walls, one of the outer side walls along which the carrier 2 lies in the X direction is configured as a first side wall 23, and the other three outer side walls are configured as second side walls 24. The single-sided magnetic group 5 is mounted on the first side wall 23, and in correspondence with the single-sided magnetic group 5, one of the four cavity walls of the mounting cavity 11 opposite to the single-sided magnetic group 5 is defined as a first cavity wall 1181, and the other cavity walls of the mounting cavity 11 are defined as second cavity walls 1182. The coil group 6 is arranged on the first cavity wall 1181, and after the single-sided magnetic group 5 is mounted in the mounting cavity 11 along with the carrier 2, the coil group 6 is distributed opposite to the single-sided magnetic group 5 and can cooperate with each other. In order to ensure that the electromagnetic force generated by the single-sided magnetic group 5 and the coil group 6 after being energized can push the carrier 2 to move, each outer side wall of the carrier 2 and each cavity wall of the mounting cavity 11 are spaced apart, wherein the gap between the first side wall 23 and the first cavity wall 1181 is configured as a first gap 251, and the gap between each second side wall 24 and each second cavity wall 1182 is configured as a second gap 252, and the single-sided magnetic group 5 and the coil group 6 are located in the first gap 251. The first side wall 23 is provided with an extension platform 231 corresponding to the single-sided magnetic group 5, and the part of the first side wall 23 close to the two sides of the second side wall 24 (the two sides of the first side wall 23 along the Y direction) is recessed relative to the extension platform 231 to be configured as a concave surface 232, and the extension platform 231 is located between the two concave surfaces 232. As a part of the first side wall 23, the extension platform 231 has a matching plane on the side away from or facing away from the carrier 2, and the first recess 233 is recessed on the matching plane, and the single-sided magnetic group 5 is mounted in the first recess 233. In order to facilitate the installation of the single-sided magnetic group 5, the first recess 233 penetrates the bottom surface of the carrier 2 along the Z direction, so that the single-sided magnetic group 5 can be mounted in the first recess 233 from the side of the bottom surface of the carrier 2 along the Z direction.

[0031] The guiding slide shaft 7 is arranged between the carrier 2 and the cavity wall of the mounting cavity 11, and is in a cylindrical shape and used for guiding and supporting the carrier 2 after the single-sided magnetic group 5 and the coil group 6 are powered on, so that the carrier 2 slides along the Z direction. The guiding slide shaft 7 is arranged as at least two and can be arranged in the first gap 251 and / or the second gap 252. In the embodiment, the guiding slide shaft 7 is arranged as two and both are arranged in the first gap 251. In order to avoid the guiding slide shaft 7 affecting the cooperation between the coil group 6 and the single-sided magnetic group 5, the two guiding slide shafts 7 are separately arranged on the two sides of the extension platform 231 and are spaced apart and respectively face the concave surface 232. The two guiding slide shafts 7 are both arranged along the Z direction and are connected to the boss 112. The guiding slide shaft 7 can be fixed to the boss 112 and the guiding slide shaft 7 by pasting or sequentially screwing the boss 112 and the guiding slide shaft 7 by using screws. The second guiding groove 1183 in a V shape or a semicircle is concavely arranged on the first cavity wall 1181 and faces the position of the guiding slide shaft 7, opens towards the side of the mounting cavity 11 to communicate with the mounting cavity 11, and communicates with the base 1 along the Z direction away from the boss 112. The middle part of the second guiding groove 1183 is concavely arranged away from the mounting cavity 11. The first guiding groove 234 is concavely arranged on the two concave surfaces 232 and respectively faces the position of the second guiding groove 1183 and the guiding slide shaft 7. The shape of the first guiding groove 234 can be mirror-symmetrically arranged with the second guiding groove 1183, or can be other shapes. Any first guiding groove 234 and the second guiding groove 1183 facing it together form a guiding cavity, and the guiding slide shaft 7 is located in the guiding cavity and the side away from the second guiding groove 1183 is located in the first guiding groove 234. In the embodiment, one first guiding groove 234 is in a V shape, and the other first guiding groove 234 is in an L shape. The L-shaped first guiding groove 234 also opens towards the side of the guiding slide shaft 7 and communicates along the Z direction, and the L-shaped first guiding groove 234 also communicates and opens towards the side away from the V-shaped first guiding groove 234. The V-shaped first guiding groove 234 precisely positions the guiding slide shaft 7, ensures the relative position between the guiding slide shaft 7 and the base 1 and the carrier 2, enables the guiding slide shaft 7 to guide the carrier 2 along the Z direction, and enables the carrier 2 to abut on the guiding slide shaft 7 in a linear contact manner. Similarly, the carrier 2 only needs to abut on the guiding slide shaft 7 to complete the guiding. The L-shaped first guiding groove 234 only needs to abut on the carrier 2 to coarsely position the carrier 2 and limit the rotation of the carrier 2, etc. In this way, the carrier 2 is guided by the sliding cooperation between the first guiding groove 234 and the guiding slide shaft 7 along the Z direction, thereby replacing the traditional elastic sheet guiding mode and improving the service life. The guiding slide shaft 7 is in linear contact with the first guiding groove 234 when in contact, which is suitable for friction. In order to further reduce the wear of the carrier 2, the avoiding groove is concavely arranged at the middle part of the first guiding groove 234 along the Z direction, so that the avoiding groove part does not contact the guiding slide shaft 7, but can maintain the cooperation between the guiding slide shaft 7 and the carrier 2.

[0032] In the content defined by the embodiment, in order to increase the stability of the carrier 2, a limiting part 26 is arranged in each second gap 252. Two limiting parts 26 are arranged in each second gap 252, each limiting part 26 comprises a first limiting protrusion 261 protruding from the second side wall 24 and a second limiting protrusion 262 protruding from the second cavity wall 1182 opposite to the first limiting protrusion 261, and the first limiting protrusion 261 and the second limiting protrusion 262 are arranged at the same height relative to the second limiting protrusion 262, and the first limiting protrusion 261 and the second limiting protrusion 262 are not in direct contact but have a gap, which allows the carrier 2 to move in the Z direction, but when the carrier 2 moves in the X direction and the Y direction, the first limiting protrusion 261 abuts against the corresponding second limiting protrusion 262, thereby limiting the carrier 2 and reducing the risk of the carrier 2 colliding with the debris.

[0033] In the embodiment, the shell 3 is also a cuboid structure and is used to cover the outside of the base 1, and a bearing platform 1194 is protruded from the outer side wall of the base 1 at the four corners, and an L-shaped groove is recessed at the four corners of the shell 3 and riveted with the bearing platform 1194. A through hole 31 is arranged on the shell 3 opposite to the lens 4 for the lens 4 to pass through.

[0034] In the embodiment, the lens 4 is a conventional VCM motor lens 4 mounted in the assembly hole 21, which will not be described in detail here.

[0035] In the embodiment, the single-sided magnetic group 5 comprises a steel sheet 51 connected in the first groove 233 and a magnet 52 connected to the steel sheet 51.

[0036] In the embodiment, the coil group 6 comprises a circuit board 61, a magnetic iron sheet 62 connected to the circuit board 61, and a coil 63 connected to the circuit board 61 and magnetically matched with the magnet 52. In order to facilitate the circuit arrangement of the circuit board 61, a first groove 1191 is formed in the first cavity wall 1181 along the X direction for the circuit board 61 to pass through, and a second groove 1192 is formed in the first cavity wall 1181 away from the first side wall 23 along the transverse direction, the size of the second groove 1192 is larger than the size of the first groove 1191, that is, the length of the second groove 1192 is larger than the length of the first groove 1191, and the width of the second groove 1192 is larger than the width of the first groove 1191. Therefore, the second groove 1192 forms a step surface around the first groove 1191 relative to the first groove 1191, the circuit board 61 is connected to the step surface, and the coil 63 is connected to the side of the circuit board 61 facing the first groove 1191 and extends into the first groove 1191 to be close to the magnet 52.

[0037] In the content defined by the embodiment, the circuit board 61 is selected as FPC (flexible circuit board 61), and the magnetic iron sheet 62 is connected on the side of the circuit board 61 facing away from the coil 63. In order to avoid easy falling during the assembly process of the circuit board 61 and increase the difficulty, the protruding column 1193 extending along the X direction is protruded on the two sides along the Y direction on the stepped surface, and the side groove 64 for the protruding column 1193 to pass through along the X direction is formed on the circuit board 61 and the steel plate, and the side groove 64 is U-shaped and the width is greater than the diameter of the protruding column 1193. The magnetic iron sheet 62 is located on the outside of the circuit board 61. During assembly, the side groove 64 on the magnetic iron sheet 62 is aligned with the circuit board 61, and then the side groove 64 of the circuit board 61 is aligned with the protruding column 1193 so that the protruding column 1193 passes through the side groove 64, until the circuit board 61 contacts the stepped surface to complete the installation of the coil assembly 6, the coil 63 is opposite to the magnet 52, and the coil 63 and the magnet 52 are spaced apart to form a movable space, so that the circuit board 61 generates electromagnetic force to drive the carrier 2Z to move after the coil 63 is electrified. Among them, the magnetic force is generated between the magnet 52 and the magnetic iron sheet 62, so that the carrier 2 is tightly attached to the guide slide shaft 7 at this time, and the verticality of the guide slide shaft 7 is used to ensure the levelness of the carrier 2, so as to avoid the inclination of the carrier 2 to a certain extent. It should be noted that the capacitor 65 and the Drive IC (driving chip 66) are arranged on the side of the circuit board 61 facing the magnet and inside the coil 63, which can detect the position of the carrier 2 to realize closed loop.

[0038] The utility model provides a kind of electronic equipment including slide shaft type VCM motor structure.

[0039] Compared with prior art, the slide shaft type VCM motor structure and electronic equipment of the utility model, the carrier 2 generates propulsive force through the magnet 52 and the coil 63, but magnetic interference will occur between the magnet 52 and the magnet 52, and the magnet 52 will be disabled in severe cases. The single magnet 52 and the coil 63 in the utility model can better avoid interference from other three magnets 52, and the design of single-sided magnet 52 allows the spacing between other sides to be reduced, greatly saving space and reducing volume, thereby reducing production costs.
