Technical Field
[0001] This utility model relates to the field of camera technology, and in particular to a magnetic induction encoding camera device. Background Technology
[0002] Currently, with the continuous development of portable electronic products, cameras, capable of both taking photos and recording videos, are becoming increasingly popular. In existing technologies, focusing or zooming is achieved through light sensing. A light sensor is used; rotation is detected by a light grid to determine whether it's a left or right turn. An algorithm then determines the rotation angle and uses light-generated signals for identification. The drawback of this existing technology is its high sensitivity to light, making it susceptible to interference and errors.
[0003] Magnetoelectric encoders are a type of angular displacement sensor that has gradually emerged in recent years. Their main structure includes a ring magnet and a Hall element. Due to their simple structure, small space requirement, and strong anti-disturbance capability, they are now widely used in many fields such as motor control, machinery manufacturing, wind power generation, shipbuilding, aviation, radar, and military industry. However, they have not yet been applied in the field of cameras.
[0004] The application number is 202420711444.5, entitled "A Magnetic Induction Encoding Focusing or Zooming Device". It discloses magnetic induction encoding focusing or zooming, but its drawback is that it does not combine focusing and zooming, and cannot achieve focusing and zooming at the same time.
[0005] In view of this, there is a need to provide a magnetic induction encoding camera device to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is to provide a magnetic induction encoding camera device that has a simple structure, small space requirement, strong anti-disturbance ability, low cost, good reliability, and can simultaneously achieve focusing and zooming.
[0007] To address the aforementioned technical problems, this utility model provides a magnetic induction encoding camera device, comprising a fixed bracket, a zoom lens mounted in the fixed bracket, a focusing bracket mounted on the front side of the fixed bracket, a focusing ring pressure plate mounted on the front side of the focusing bracket, a zoom ring sleeved on and rotatably connected to the fixed bracket, a focusing ring sleeved on and rotatably connected to the focusing bracket, the focusing ring being positioned between the focusing ring pressure plate and the zoom ring, a sensor plate mounted on the fixed bracket, a sensor provided on the front side of the sensor plate, and a magnetic ring mounted on the focusing ring and sensing the sensor on the front side of the sensor plate.
[0008] A further improvement of this utility model is that a zoom switch is provided on the reverse side of the sensor plate, and a boss that abuts against the zoom switch is provided inside the zoom ring.
[0009] A further improvement of this utility model is that the number of zoom switches and bosses is two.
[0010] A further improvement of this utility model is that a reset device is provided on both sides of the zoom ring.
[0011] A further improvement of this utility model is that the reset device adopts a reset spring, and the reset spring elastically abuts against the zoom ring and the fixed bracket.
[0012] A further improvement of this invention is that the reset spring is replaced by a tension spring.
[0013] A further improvement of this utility model is that it also includes a processor, and the zoom lens, the sensor on the front of the sensor board, and the zoom switch are electrically connected to the processor.
[0014] A further improvement of this invention is that the magnetic ring includes a bottom ring and a plurality of magnets mounted on the bottom ring.
[0015] A further improvement of this invention is that the number of magnets is 8 to 60.
[0016] A further improvement of this invention is that the number of magnets is 30.
[0017] Compared to existing technologies, the advantages of this invention are as follows: The sensor and magnetic ring generate signals, which are then transmitted to the processor. After processing, the signals are sent to the zoom lens, which adjusts its focus accordingly. A protrusion within the zoom ring abuts against the zoom switch, generating a signal that is also transmitted to the processor. This signal is then processed and sent to the zoom lens, which adjusts its zoom accordingly. A reset spring allows the zoom ring 5 to automatically reset after rotation. This invention features a simple structure, requires little space, has strong anti-disturbance capabilities, low cost, high reliability, and can simultaneously achieve focusing and zooming. Light and electricity cannot interfere with the magnetic ring, thus providing strong anti-disturbance capabilities. Attached Figure Description

[0049] like Figure 1-6As shown, this utility model provides a magnetic induction encoding camera device, which includes a fixed bracket 1, a zoom lens 2, a focusing bracket 3, a focusing ring pressure plate 4, a zoom ring 5, a focusing ring 6, a sensor plate 7, a magnetic ring 8, a zoom switch 9, a reset device 10, and a decorative plate 20.
[0050] Specifically, such as Figure 1-6 As shown, the fixing bracket 1 is an integral circular ring with a hollow interior. The fixing bracket 1 has four fasteners 11 and one through hole 12. The zoom lens 2 is placed in the hollow part of the fixing bracket 1 and fixedly connected to it with screws. The focusing bracket 3 is fixedly installed on the front side of the fixing bracket 1 with screws. The focusing ring pressure plate 4 is fixedly installed on the front side of the focusing bracket 3 with screws. The decorative plate 20 is fixedly installed on the front side of the focusing ring pressure plate 4.
[0051] Specifically, such as Figure 1-6 As shown, the zoom lens 2 is an optical zoom lens. Optical zoom lenses are existing technology and are available on the market, so they will not be described in detail here.
[0052] Specifically, such as Figure 1-6 As shown, the focusing bracket 3 is an integral circular ring with a hollow interior. The focusing ring pressure plate 4 is an integral circular ring with a hollow interior. The decorative plate 20 is an integral circular ring with a hollow interior.
[0053] Specifically, such as Figure 1-6 As shown, the zoom ring 5 is an integral circular ring with a hollow interior. The zoom ring 5 has a boss 51 that contacts the zoom switch 9. The zoom ring 5 is fitted onto the fixed bracket 1 and rotates with the fixed bracket 1. Four fasteners 11 on the fixed bracket 1 are used to hold the zoom ring 5 in place, preventing axial movement of the zoom ring 5. There are two bosses 51.
[0054] Specifically, such as Figure 1-6 As shown, the focusing ring 6 is an integral circular ring with a hollow interior. The focusing ring 6 is positioned between the focusing ring pressure plate 4 and the zoom ring 5, and is sleeved on the focusing bracket 3 and rotatably connected to the focusing bracket 3.
[0055] Specifically, such as Figure 1-6 As shown, the sensor board 7 is a PCB board. Two sensors 71 are mounted on the front of the sensor board 7, and two zoom switches 9 are mounted on the back of the sensor board 7. The sensor board 7 is fixedly mounted to the mounting bracket 1 with screws. The through hole 12 on the mounting bracket 1 is used for the wires of the sensors 71 and zoom switches 9 to pass through. The sensors 71 are Hall sensors.
[0056] Specifically, such as Figure 1-6As shown, the magnetic ring 8 includes a bottom ring 81 and a plurality of magnets 82 mounted on the bottom ring 81. The number of magnets 82 is 8 to 60, specifically 30 magnets 82.
[0057] Specifically, such as Figure 1-6 As shown, a reset device 10 is provided on both sides of the zoom ring 5. The reset device 10 is a reset spring, which elastically abuts against the zoom ring 5 and the fixed bracket 1. The reset spring can be replaced by a tension spring.
[0058] This utility model also includes a processor. The zoom lens 2, the sensor 71 on the front of the sensor board 7, and the zoom switch 9 are all electrically connected to the processor. The sensor 71 induces a current signal with the magnetic ring 8, which belongs to the field of magneto-electric encoder technology and is existing technology, so it will not be described in detail here. The zoom switch 9 sends a signal to the processor, and the processor then sends a signal to the zoom lens 2 to zoom. How zooming is achieved is also existing technology and will not be described in detail here.
[0059] Assembly of this utility model: The zoom lens 2 is placed in the fixed bracket 1 and secured with three screws. A return spring is placed inside the zoom ring 5, and the zoom ring 5 is then fastened to the fixed bracket 1, with the return spring elastically pressing against the zoom ring 5 and the fixed bracket 1. Four fasteners 11 on the fixed bracket 1 secure the zoom ring 5, preventing axial movement. The focusing bracket 3 and sensor plate 7 are respectively fixed to the fixed bracket 1 with screws. The wires of sensor 71 and zoom switch 9 are electrically connected to the processor through the through hole 12 on the fixed bracket 1. A magnetic ring 8 is fixedly installed inside the focusing ring 6, and the focusing ring 6 with the magnetic ring 8 is rotated and placed on the focusing bracket 3. The focusing ring pressure plate 4 is then fixed to the focusing bracket 3 with screws, preventing axial movement of the focusing ring 6, allowing only rotation. The return spring allows the zoom ring 5 to automatically reset after rotation.
[0060] Working principle: Rotating the focus ring 6 causes the magnetic ring 8 to rotate as well. The sensor 71 on the front of the sensor plate 7 senses the magnetic ring 8, generating a current signal. The processor receives the signal from the sensor 71, processes it, and then sends it to the zoom lens 2. The zoom lens 2 adjusts its focus accordingly based on the signal from the processor. Rotating the zoom ring 5 causes the protrusion 51 inside the zoom ring 5 to contact the zoom switch 9, generating a signal. This signal is then sent to the processor, which processes it and sends it to the zoom lens 2. The zoom lens 2 adjusts its zoom accordingly based on the signal from the processor.
[0061] The beneficial effects of this utility model are as follows: Sensor 71 and magnetic ring 8 sense and generate a signal, which is then transmitted to the processor. After processing, the signal is sent to zoom lens 2, which makes corresponding focus adjustments based on the signal sent by the processor. The protrusion 51 inside zoom ring 5 abuts against zoom switch 9 to generate a signal, which is also transmitted to the processor. After processing, the signal is sent to zoom lens 2, which makes corresponding zoom adjustments based on the signal sent by the processor. A reset spring allows zoom ring 5 to automatically reset after rotation. This utility model features a simple structure, requires little space, has strong anti-disturbance capability, low cost, high reliability, and can simultaneously achieve focusing and zooming; light and electricity cannot interfere with the magnetic ring, thus providing strong anti-disturbance capability.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
