Detailed Description
This example is a preferred embodiment of the present invention, and other principles and basic structures are the same as or similar to those of this example, and all fall within the scope of the present invention.
An embodiment of an infrared lens shutter adopting a split type threaded connection structure of the present invention is shown with reference to fig. 1-6, and includes a driving arm 24 and a light shielding blade 3 connected by a screw, a connection boss 322 is provided on the light shielding blade 3, and a driving arm connection hole 321 is provided in the connection boss 322. The driving arm connecting hole 321 comprises a threaded connection half hole 3211 and a locking half hole 3212, an inner thread is arranged on the inner wall of the threaded connection half hole 3211 and used for being connected with an external thread of a screw, and the locking half hole 3212 is used for installing the connecting convex part 242. The connection protrusion 242 is arranged at the position where the driving arm 24 is connected with the shading blade 3, the connection protrusion 242 extends into the driving arm connection hole 321, and one side of the connection protrusion is connected with the external screw thread of the screw in a matching way. The coupling protrusion 242 is inserted into the locking half hole 3212 of the coupling hole 321, the female screw of the coupling protrusion 242 and the female screw of the inner wall of the threaded coupling half hole 3211 of the coupling hole 321 are formed into a screw hole, and the screw is fitted into the screw hole to fix the coupling protrusion 242 and the coupling hole 321 together, and the driving arm 24 is connected to the light shielding blade 3. The method for connecting the shading blade 3 and the driving arm 24 can avoid the situation that the driving arm 24 bursts in use and the action of the shutter is invalid because the driving arm 24 is very slim and the screw hole is formed at the top end of the driving arm; secondly, the split type screw threads are used, so that the thickness of the threaded connecting piece is reduced, the effective length of the threaded connection is increased, and the screw is more firmly installed; finally, the problems of possible glue overflow and action failure caused by ageing of the glue dispensing part in the prior art are avoided by connecting the shading blade 3 and the driving arm 24 by using a glue dispensing method. In order to further strengthen the strength of the connection part between the shading blade 3 and the driving arm 24, prevent the shading blade 3 from deforming, prolong the service life of the shutter, and provide a connection boss 322 for preventing the shading blade at the periphery of the connection hole from deforming on the shading blade 3, in this embodiment, the shading blade 3 is provided with a connection hole 321, so the connection boss 322 is provided on the anti-deformation driving connection arm 32, and the connection boss 322 is a boss provided along the edge of the connection hole 321 with the connection hole 321 as the center.
The shading blade 3 comprises a shading baffle 31 made of metal for shading light, a shading baffle supporting arm 311 for supporting the shading baffle is arranged on the shading baffle 31, and an anti-deformation driving connecting arm 32 made of plastic is connected to the shading baffle supporting arm 311. The light shielding blade thus provided can transfer the receiving position at the time of shutter operation to the relatively strong deformation-preventing drive connection arm 32, thereby preventing deformation of the light shielding blade 3 after long-term use. In order to make the connection between the shading baffle 31 and the deformation-preventing driving connecting arm 32 more firm, the invention adopts an insert injection molding process to connect two components together, wherein the shading baffle 31 is an insert. The light shielding barrier 31 is placed in a mold during injection molding, and a material for manufacturing the deformation-preventing driving connection arm 32 is injected, so that the light shielding barrier support arm 311 is embedded in the deformation-preventing driving connection arm 32. The light shielding baffle support arm 311 is also provided with an elliptical fixing hole, so that the connection of the anti-deformation drive connecting arm 32 can be firmer.
The infrared lens shutter of the embodiment of the invention further comprises a shutter base 1, wherein a series of mounting positions are arranged on the shutter base 1, and fine auxiliary parts such as wires are mounted. The shutter base 1 is also provided with a driving motor assembly 2 for driving the shutter to open and close, the driving motor assembly 2 comprises a driving motor shell 21, and the driving motor shell 21 is a cylindrical iron. The driving coil 22 is installed in the driving motor housing 2, and the driving coil 22 in this embodiment is wound on the coil base 25 and the driving motor installation end cover 26 by using enameled wires, and other kinds of suitable coils can be adopted in actual production. The driving coil 22 is internally provided with a permanent magnet rotating member 23, the permanent magnet rotating member 23 is a cylindrical permanent magnet, and a driving arm connecting and mounting hole 231 is arranged in the middle. The drive arm attachment mounting hole 231 is a through hole in which the drive arm 24 is mounted. The driving arm 24 includes a driving arm body mounted in the driving arm connection mounting hole 231, and a driving arm body extending out of the driving arm connection mounting hole 231. The driving arm 24 in this embodiment is in a tuning fork shape, and the arm body of the driving arm is in an L shape, and two driving arms are symmetrically arranged at two sides of the same end of the driving arm body. In actual production, the driving arm 24 is changed into other shapes and structures according to the convenience of production and use. The permanent magnet rotating piece 23 is provided with an anti-slip limiting structure, which is an anti-slip limiting groove 232 arranged on the bottom surface of the permanent magnet rotating piece 23, and the transverse line part of the L-shaped driving arm body is arranged in the anti-slip limiting groove 232, so that the driving arm 24 can be driven when the permanent magnet rotating piece 23 rotates. The vertical line portion of the L-shaped driving arm body is connected to the light shielding blade 3 of the shutter, and when the driving arm 24 is driven by the permanent magnet rotor 23, the light shielding blade 3 is also driven to open and close. In order to prevent the permanent magnet rotator 23 and the driving arm 24 from moving at will when rotating in the coil base 25, the driving arm 24 is provided with a fixing shaft mounting hole 241 in its main body, a fixing shaft 27 is mounted in the fixing shaft mounting hole 241, the fixing shaft 27 is inserted in the coil base 25, and the permanent magnet rotator 23 and the driving arm 24 are pivoted around the fixing shaft 27 when rotating. In production applications, the drive motor mounting end cap 26 may also be integrally molded to the shutter base 1 in order to avoid mounting errors and reduce mounting procedures. When in installation, the permanent magnet rotating piece 23 is firstly installed in the coil base 25, then the coil base 25 is installed on the integrally formed driving motor installation end cover 26, the installed components are put on a winding machine together to install the driving coil 22, and finally the driving motor shell 21 is sleeved.
The invention avoids the direct impact of the shading blade and the shutter base, reduces the acting force received by the shading blade in the shutter opening and closing process, and the invention arranges a buffer gasket mounting bracket 12 on the shutter base 1, and installs a buffer gasket 11 made of buffer material in the buffer gasket mounting bracket 12. Since the shutter needs to perform two actions of opening and closing, the deformation-preventing driving connection arm 32 receives impact forces in two different directions, so that two cushion mounting brackets 12 are provided for the door opening and closing, namely a door opening cushion bracket 121 for the door opening action and a door closing cushion bracket 122 for the door closing action. The door opening bumper bracket 121 is provided at a position of the shutter base 1 close to the driving motor group 2, and the door opening impact bumper 111 is installed in the door opening bumper bracket 121. The shutter charge cushion bracket 122 is provided at a position of the shutter base 1 away from the driving motor group 2, and the shutter impact charge cushion 112 is mounted in the shutter charge cushion bracket 122. Corresponding to the impact buffer mechanism on the shutter base 1, the drive connection arm 32 is provided with an impact-preventing protrusion 323, and the impact-preventing protrusion 323 is also provided with a door opening impact-preventing protrusion 3232 and a door closing impact-preventing protrusion 3231 for opening and closing door actions. In this embodiment, the door opening anti-collision protrusion 3232 corresponds to the door opening buffer gasket bracket 121 on the shutter base 1, is disposed on the edge of the opposite surface of the driving connection arm 32 to the shutter base 1, and is a protrusion protruding toward the shutter base 1, and is close to the position of the driving motor unit 2; the door-closing collision preventing projection 3231 corresponds to the door-closing cushion pad bracket 122 on the shutter base 1, is provided on the edge of the drive connection arm 32, and is a projection on the side of the drive connection arm 32 at a position away from the drive motor unit 2. Since the shutter opening and closing operations are very frequent, if the same set of impact buffer mechanisms is used for the opening and closing operations, the buffer mechanisms are relatively easy to damage, and the drive connection arm 32 is also easy to deform due to the stress of the same point for a long time, so the present embodiment provides corresponding buffer mechanisms for different operations. In the door opening action, the door opening anti-collision bulge 3232 collides with the door opening collision buffer pad 111 arranged in the door opening buffer pad bracket 121, the door opening collision buffer pad 111 effectively buffers collision force, and the stress of the driving connecting arm 32 is reduced. In the door closing operation, the door closing collision preventing protrusion 3231 collides with the door closing collision buffer pad 112 mounted in the door closing buffer pad holder 122, the door closing collision buffer pad 112 buffers the collision force, and the force applied to the driving connection arm 32 during the operation is reduced.
When the light-shielding blade is mounted, the connection convex part 242 on the driving arm 24 is inserted into the locking half hole 3212 of the connection hole 321, and then the screw is mounted into the screw hole to fix the connection convex part 242 and the connection hole 321 together, so that the driving arm 24 and the light-shielding blade 3 can be firmly connected together without using glue or the like for bonding.
When the sliding shutter is used, the lead wire arranged on the shutter base 1 is connected with the driving motor component 2, the driving motor component 2 is electrified, the permanent magnet rotating piece 23 starts to rotate under the action of the magnetic field of the driving coil 22, the driving arm 24 arranged in the driving arm connecting mounting hole 231 is driven to rotate, and the limiting groove 232 clamps the arm body position of the driving arm 24, so that the driving arm 24 is ensured not to slip in rotation. The driving arm 24 drives the shading blade 3 to switch between the door opening state and the door closing state, and the light entering the camera is replaced. The connecting convex part 242 on the driving arm 24 is strong enough, and the situation that the driving arm 24 bursts in use and the shutter action fails due to the fact that the screw hole is formed in the top end of the driving arm 24 directly does not occur.
The split threaded connection structure adopts screw connection, so that the falling problem caused by ageing of plastics in a welding or dispensing fixing mode can be avoided; secondly, the thickness of the threaded connecting piece is reduced and the effective length of the threaded connection is increased by using split threads; meanwhile, as the threads are respectively arranged on the two connecting pieces, screw holes are not required to be formed on the two connecting pieces, and when the screw is used on some tiny workpieces such as infrared shutter parts, the probability of damage of the connecting parts of the parts can be reduced.
