Description

Technical Field

[0001] The present invention relates to the field of camera technology, and in particular to a sliding shaft type VCM motor structure and electronic equipment. Background Art

[0002] VCM motor, or Voice Coil Motor, is a special form of direct-drive motor. VCM motor is based on Lorenz's law. When the carrier coil is in a magnetic field, the energized coil will generate a magnetic field, which interacts with the permanent magnetic field, thereby driving the load device (such as the lens) to perform linear reciprocating motion. Changing the strength and direction of the current can change the size and direction of the magnetic field, thereby controlling the linear motion frequency and distance of the load device. In short, after the current is supplied to the coil, the magnetic field in the VCM motor is used to generate a force to push the carrier coil (lens), and the precise movement of the lens is controlled by controlling the size and direction of the coil current.

[0003] The main structural components of the existing VCM motor include an outer shell, a spring, a lens carrier, a magnet and a base. Among them, the traditional VCM motor uses spring technology to achieve the stability of the VCM motor's Z-direction movement, but the traditional spring pulls the lens carrier due to the influence of magnetic force during use, thereby driving the lens carrier to move along the Z direction. However, since the overall mass of the lens carrier and the lens mounted on the lens carrier is larger than that of the spring, this causes the spring to often deform, break and other undesirable conditions during use. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1 to 7 The sliding shaft type VCM motor structure of the present invention comprises a base 1 having a mounting cavity 11 thereon, a carrier 2 movably mounted in the mounting cavity 11, a housing 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 pass out of the housing 3, and a single-sided magnetic group 5 connected to one of the outer side walls of the carrier 2 corresponding to a coil group 6 arranged on the base 1 by the single-sided magnetic group. The housing 3 and the base 1 are buckled with each other to play a fixed supporting role; the carrier 2 is used to screw into the lens 4; the single-sided magnetic group 5 is used to generate a fixed magnetic field, and the single-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 to achieve the focusing of the lens 4.

[0028] In this embodiment, the base 1 is a rectangular parallelepiped structure having a length, a width, and a height, and the length and the width are similar or the same and are roughly square. With the height of the base 1 as the Z direction as a reference, the direction in which the length of the base 1 is located is configured 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 configured as the top surface and the bottom surface of the base 1. A mounting cavity 11 with a shape similar to that of the base 1 and in a rectangular parallelepiped shape is opened on the base 1 along the Z direction from the top surface, and the mounting cavity 11 penetrates the base 1 along the Z direction. When the structure of the present invention is used in a camera, light is emitted from one side of the top surface of the base 1 to one side of the bottom surface of the base 1 along the Z direction. The side of the mounting cavity 11 opening toward the top surface is defined as the open side 111, and the carrier 2 is installed in the mounting cavity 11 from the open side 111. The housing 3 is installed on the base 1 from the open side 111 and blocks the open side 111 to prevent the carrier 2 from escaping from the open side 111. In order to prevent the carrier 2 from escaping from the mounting cavity 11, a boss 112 is formed on the side of the mounting cavity 11 away from the open side 111 along the Z direction, that is, the side of the mounting cavity 11 facing the bottom surface and along the edge of the inner wall of the mounting cavity 11. The boss 112 is a square frame structure as a whole and has four side frames. The four side frames are jointly arranged to form a hole channel 113 on the inside that connects the mounting cavity 11 and the outside of the base 1 along the Z direction. The length and width of the hole channel 113 are smaller than the length and 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 and prevent the carrier 2 from escaping from the mounting cavity 11 from the bottom surface of the base 1. Since the entire base 1 is relatively small, especially when the present invention is used in the field of mobile phone cameras, in order to ensure the quality of the boss 112, a 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, each side frame of the boss 112 is provided with a pinhole 115 connected along the Z direction, and the pinhole 115 intersects with the cavity where the reinforcing rib 114 is located in the boss 112, so that the reinforcing rib 114 can be moved by inserting a needle-like object therein, thereby adjusting the position of the reinforcing rib 114. In order to reduce the wear between the carrier 2 and the boss 112, the four corners of the boss 112 are protruding toward the open side 111 to form an end platform 116, and the height of the end platform 116 is slightly higher than the height of other parts of the boss 112, so that when the carrier 2 moves toward the hole channel 113 along the Z direction, the carrier 2 contacts the end platform 116 so that the end platform 116 plays a lower limit role for the carrier 2, and the pinhole 115 is located on the boss 112 outside the end platform 116. In this embodiment, the end platform 116 can be made of elastic materials such as silicone, which can reduce the risk of the motor hitting the chip while limiting the lower position. Correspondingly, the entire boss 112 is made of elastic material, so it is necessary to set the reinforcing rib 114 to ensure the elastic support of the end platform 116 to the carrier 2.Since the entire sliding shaft VCM motor structure is used in electronic equipment assembly, some modules of the electronic equipment may need to extend from the hole channel 113 into the installation cavity 11. Therefore, an avoidance groove 117 connected along the Z direction and toward one side of the hole channel 113 is provided at the corresponding module position of the boss 112 as needed, thereby reducing material usage while avoiding the module and saving costs to a certain extent.

[0029] In this embodiment, the shape of the carrier 2 is similar to that of the mounting cavity 11 and both are rectangular parallelepiped structures, 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 can be movably 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, and an assembly hole 21 that passes through the top surface and the bottom surface of the carrier 2 is opened in the Z direction on the carrier 2, and the lens 4 is assembled in the assembly hole 21, so that the carrier 2 carries the lens 4 and when the single-sided magnetic group 5 cooperates with the coil group 6, the lens 4 moves with the carrier 2 for focusing and distance adjustment. Among them, the assembly hole 21 is located at the center of the carrier 2, and grooves 22 are concavely provided at the four corners of the top surface and the bottom surface of the carrier 2 to save material and prevent the deformation of the carrier 2.

[0030] In this embodiment, the carrier 2 has four outer side walls, one of which is located along the X direction as the first side wall 23, and the other three outer side walls are configured as the second side wall 24. The single-sided magnetic group 5 is installed on the first side wall 23. In order to correspond to the single-sided magnetic group 5, one of the four cavity walls of the installation cavity 11 that is directly opposite to the single-sided magnetic group 5 is defined as the first cavity wall 1181, and the other cavity walls of the installation cavity 11 are defined as the second cavity wall 1182. The coil group 6 is arranged on the first cavity wall 1181. After the single-sided magnetic group 5 is installed in the installation cavity 11 along with the carrier 2, the coil group 6 and the single-sided magnetic group 5 are directly opposite 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 power-on can push the carrier 2 to move, each outer wall of the carrier 2 and each cavity wall of the installation 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 both located in the first gap 251. An extension platform 231 is convexly provided on the first side wall 23 corresponding to the single-sided magnetic group 5, and the first side wall 23 is respectively close to the two sides of the second side wall 24 (the two sides of the first side wall 23 along the Y direction) The part is concave relative to the extension platform 231 and is 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, a mating plane is provided on a side surface of the extension platform 231 away from or facing away from the carrier 2, and a first groove 233 is concavely provided on the mating plane, and the single-sided magnetic group 5 is installed in the first groove 233. In order to facilitate the installation of the single-sided magnetic group 5, the first groove 233 penetrates the bottom surface of the carrier 2 along the Z direction, so that the single-sided magnetic group 5 can be installed in the first groove 233 from one side of the bottom surface of the carrier 2 along the Z direction.

[0031] A guide slide shaft 7 is arranged between the carrier 2 and the cavity wall of the installation cavity 11. The guide shaft is cylindrical and is used to guide and support the carrier 2 after the single-sided magnetic group 5 and the coil group 6 are energized, so that the carrier 2 slides along the Z direction. The guide slide shafts 7 are set to at least two and can be arranged in the first gap 251 and / or the second gap 252. In this embodiment, the guide slide shafts 7 are set to two and are both arranged in the first gap 251. In order to avoid the guide slide shaft 7 affecting the coordination between the coil group 6 and the single-sided magnetic group 5, the two guide slide shafts 7 are respectively arranged on both sides of the extension platform 231 and are spaced apart from the concave surface 232. Among them, the two guide slide shafts 7 are arranged along the Z direction and connected to the boss 112. The guide slide shaft 7 can be screwed to the boss 112 and the guide slide shaft 7 in sequence by gluing or using screws to fix the guide slide shaft 7. A V-shaped or semicircular second guide groove 1183 is recessed at the position of the first cavity wall 1181 directly opposite to the guide slide shaft 7. The second guide groove 1183 is open toward the carrier 2 to connect to the installation cavity 11, and the second guide groove 1183 is connected to the base 1 along the Z direction toward the side away from the boss 112. The middle part of the second guide groove 1183 is recessed toward the side away from the installation cavity 11. A first guide groove 234 is recessed at the positions directly opposite to the second guide groove 1183 and the guide slide shaft 7 on the two concave surfaces 232. The shape of the first guide groove 234 can be mirror-symmetrical with the second guide groove 1183, or can be other shapes. Any first guide groove 234 and the second guide groove 1183 directly opposite to it are jointly surrounded to form a guide cavity, and the guide slide shaft 7 is located in the guide cavity and the side facing away from the second guide groove 1183 is located in the first guide groove 234. In this embodiment, one of the first guide grooves 234 is V-shaped, and the other first guide groove 234 is L-shaped. The L-shaped first guide groove 234 is also open toward one side of the guide slide shaft 7 and connected along the Z direction, and the L-shaped first guide groove 234 is also open toward the side away from the V-shaped first guide groove 234. The V-shaped first guide groove 234 precisely positions the guide slide shaft 7, ensures the relative position between the guide slide shaft 7 and the base 1 and the carrier 2, and enables the secondary guide slide shaft 7 to guide the carrier 2 along the Z direction while allowing the carrier 2 to bear on the guide slide shaft 7 in a line contact manner. Similarly, the carrier 2 only needs to bear on the guide slide shaft 7 to complete the guidance. The L-shaped first guide groove 234 only needs to bear on the carrier 2 to roughly position the carrier 2 and limit the rotation of the carrier 2. In this way, the carrier 2 is guided by the first guide groove 234 and the guide slide shaft 7 in the Z direction, thereby replacing the traditional spring guide method and improving the service life. The inlet guide slide shaft 7 is in friction with the first guide groove 234 in a suitable line contact manner, but in order to further reduce the wear of the carrier 2, avoidance grooves are recessed at the middle positions of the two first guide grooves 234 along the Z direction, so that the avoidance groove part will not contact the guide slide shaft 7, but can maintain the cooperation between the guide slide shaft 7 and the carrier 2.

[0032] In the content defined in this embodiment, in order to increase the stability of the carrier 2, a limiting portion 26 is provided in each second gap 252. Two spaced limiting portions 26 are provided in each second gap 252, and each limiting portion 26 includes a first limiting protrusion 261 convexly provided on the second side wall 24 and a second limiting protrusion 262 convexly provided on the second cavity wall 1182 just opposite to the first limiting protrusion 261, and the first limiting protrusion 261 and the second limiting protrusion 262 are close to the second limiting protrusion 262 at the same installation height, and the first limiting block and the second limiting protrusion 262 are not in direct contact but leave a gap, the gap enables the carrier 2 to move along the Z direction, but when the carrier 2 moves in the X direction and the Y direction, the first limiting protrusion 261 will bear on the corresponding second limiting protrusion 262, thereby limiting the carrier 2 and reducing the risk of collision and chipping of the carrier 2.

[0033] In this embodiment, the housing 3 is also a rectangular parallelepiped structure and is used to cover the outside of the base 1. On the outer wall of the base 1 and at the four corners, there are convex support platforms 1194, and at the four corners of the housing 3, there are concave L-shaped grooves riveted to the support platforms 1194. A through hole 31 is provided on the housing 3 at a position directly facing the lens 4 for the lens 4 to pass through.

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

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

[0036] In this embodiment, the coil group 6 includes a circuit board 61, a magnetic magnet 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 slot 1191 for the circuit board 61 to pass through is opened on the first cavity wall 1181 along the X direction, and a second slot 1192 is opened along the horizontal direction from the side of the first slot 1191 away from the first side wall 23. The size of the second slot 1192 is larger than the size of the first slot 1191, that is, the length of the second slot 1192 is larger than the length of the first slot 1191, and the width of the second slot 1192 is larger than the width of the first slot 1191. For this reason, the second slot 1192 is formed with a step surface around the outside of the first slot 1191 relative to the first slot 1191, and the circuit board 61 is connected to the step surface. The coil 63 is connected to the side of the circuit board 61 facing the first slot 1191 and extends into the first slot 1191 and close to the magnet 52.

[0037] In the content defined in this embodiment, the circuit board 61 uses FPC (flexible circuit board 61), and the side of the circuit board 61 facing away from the coil 63 is connected to the magnetic iron sheet 62. In order to prevent the circuit board 61 from falling off easily during assembly and increase the difficulty, a protrusion 1193 extending along the X direction is protruded on both sides of the step surface and along the Y direction, and a side groove 64 is provided on the circuit board 61 and the steel plate for the protrusion 1193 to pass through along the X direction. The side groove 64 is U-shaped and its width is greater than the diameter of the protrusion 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 for connection, and then the side groove 64 of the circuit board 61 is aligned with the protrusion 1193 so that the protrusion 1193 passes through the side groove 64 until the circuit board 61 contacts the step area to complete the installation of the coil group 6, the coil 63 is directly opposite the magnet 52, and there is a movable space between the coil 63 and the magnet 52, so that the circuit board 61 generates an electromagnetic force to drive the carrier 2 to move in the Z direction after the coil 63 is energized. Among them, the magnet 52 and the magnetic iron sheet 62 generate suction, so that the connected carrier 2 is closely attached to the guide slide shaft 7 at this time, and the verticality of the guide slide shaft 7 as a whole is relied on to ensure the horizontality of the carrier 2, so as to avoid the tilt of the carrier 2 to a certain extent. It should be noted that a capacitor 65 and a driver IC (driver chip 66) are arranged on the side of the circuit board 61 facing the magnet and located inside the coil 63, which can detect the position of the carrier 2 to achieve a closed loop.

[0038] The invention provides an electronic device including a sliding shaft type VCM motor structure.

[0039] Compared with the prior art, the sliding shaft VCM motor structure and electronic equipment of the present invention generate driving force through the magnet 52 and the coil 63, but magnetic interference will be generated between the magnets 52 and 52, which may cause the magnet 52 to fail in severe cases. The single magnet 52 and coil 63 design of the present invention can better avoid interference from the magnet 52 on the other three sides. At the same time, the design of the single-sided magnet 52 can reduce the spacing between the other sides, greatly saving space and reducing the volume, thereby reducing production costs.
