Filters are used to select specific wavelengths of light to meet different application requirements. Traditional filter switchers typically employ independent motor-driven systems, switching filters by rotation or translation. However, existing technologies suffer from the following major problems:

[0003] Existing filter switching devices often employ a discrete design, with the motor, filter holder, and control system installed separately. This leads to complex assembly and maintenance, and installation errors can affect the final optical performance. Furthermore, the overall stability of the device is greatly affected by the external environment, which is not conducive to long-term use.

[0014] Furthermore, the second connector includes an upper connecting portion and a lower connecting portion arranged alternately. The shape of the connection points between the upper connecting portion and the lower connecting portion and the synchronous shaft is semi-circular. The lower end of the upper connecting portion is slidably connected to the synchronous shaft, and the upper end of the lower connecting portion is slidably connected to the synchronous shaft.

[0015] Furthermore, the integrated bracket has buckles on both sides of its bottom, and slots are provided on both sides of the bottom frame. The integrated bracket is fastened to the slots on both sides of the bottom frame by the buckles on both sides.

[0017] Furthermore, both the air inlet and the air outlet are equipped with filters.

[0018] The beneficial effects of this utility model are:

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] Reference Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides an integrated device for a filter switcher and a motor, which can realize the integrated design of the motor assembly 5 and the filter switching assembly 3, thereby improving the integration degree. It includes a bottom frame 1, an integrated bracket 2 detachably connected to the upper end of the bottom frame 1, a motor assembly 5 provided at the upper end of the integrated bracket 2, a filter switching assembly 3 provided inside the integrated bracket 2, and a lens placement port 4 opened in the bottom frame 1. The lens placement port 4 is located directly below the motor assembly 5 and aligned with the center of the motor assembly 5.

[0029] Motor assembly 5 includes a motor housing, multiple motor magnets, a motor coil, and a carrier. The carrier is disposed inside the motor housing, the motor coil is wound around the outside of the carrier, and each motor magnet is disposed between the motor housing and the carrier.

[0030] The filter switching assembly 3 includes a rotary drive component 31, a rotating shaft 32, a spiral connecting strip 33, a synchronous shaft 34, a filter bracket 35, and a filter 36. The rotary drive component 31 and the synchronous shaft 34 are fixed inside the integrated bracket 2. The filter 36 is fixedly embedded in the filter bracket 35. The filter bracket 35 has a first connector 6 and a second connector 7 on both sides. The spiral connecting strip 33 is fixedly wound around the rotating shaft 32. The output shaft of the rotary drive component 31 is coaxially fixedly connected to the rotating shaft 32. The end of the rotating shaft 32 away from the rotary drive component 31 is rotatably connected to the inner side of the integrated bracket 2. The synchronous shaft 34 is parallel to the rotating shaft 32. The first connector 6 is engaged and rotatably connected to the spiral connecting strip 33. The second connector 7 is slidably limited and connected to the synchronous shaft 34.

[0031] When the rotating drive component 31 drives the rotating shaft 32 to rotate, the spiral connecting bar 33 rotates, causing the filter 36 on the filter bracket 35 to move towards the lens placement port 4 to directly above or away from the lens placement port 4.

[0032] Specifically, in this embodiment, the bottom frame 1 is made of metal or high-strength engineering plastic to provide a stable support structure. The upper end of the bottom frame 1 is detachably connected to the integrated bracket 2 for easy installation and maintenance of the device. The bottom frame 1 is provided with a lens placement port 4, which is located directly below the motor assembly 5 and aligned with the center of the motor assembly 5 to ensure that the filter 36 is accurately aligned with the optical path.

[0033] Motor assembly 5 consists of a motor housing, motor magnets, motor coils, and a carrier. The carrier is located inside the motor housing, the motor coils are wound around the outside of the carrier, and multiple motor magnets are positioned between the motor housing and the carrier to achieve stable electromagnetic drive.

[0034] The filter switching assembly 3 consists of a rotary drive component 31, a rotating shaft 32, a spiral connecting bar 33, a synchronous shaft 34, a filter holder 35, and a filter 36. The rotary drive component 31 is fixed inside the integrated bracket 2, and its output shaft is coaxially connected to the rotating shaft 32 to ensure stable transmission. The spiral connecting bar 33 is fixedly wound around the rotating shaft 32 and drives the filter 36 on the filter holder 35 to perform precise linear motion. The filter holder 35 has a first connecting member 6 and a second connecting member 7 on both sides, wherein:

[0035] The first connector 6 is engaged and rotatably connected to the spiral connecting bar 33, thereby converting the rotary drive into linear motion.

[0036] The second connector 7 is slidably limited and connected to the synchronous shaft 34 to ensure that the movement direction of the filter bracket 35 (together with the filter 36) is stable and does not deviate.

[0037] Working principle of Example 1:

[0038] When the rotation drive component 31 drives the rotating shaft 32 to rotate in the forward direction: the spiral connecting bar 33 rotates in the forward direction, pushing the filter bracket 35 (through the first connecting member 6) to move towards the lens placement port 4 until the filter 36 is precisely located directly above the lens optical axis.

[0039] When the rotary drive component 31 drives the rotating shaft 32 to rotate in the opposite direction, the spiral connecting bar 33 rotates in the opposite direction, causing the filter bracket 35 (along with the filter 36) to move away from the lens mounting opening 4 and exit the optical path. The sliding limit of the second connecting piece 7 on the synchronous shaft 34 ensures the linearity and stability of the movement process.

[0040] This embodiment is applicable to optical equipment such as microscopes, spectrometers, and imaging systems, enabling multispectral switching. It can be used in fields such as industrial inspection, biomedical imaging, and remote sensing measurement, improving the flexibility and adaptability of optical systems.

[0041] This embodiment provides an efficient, accurate, and stable filter switching solution through a compact and integrated structural design. It solves the shortcomings of traditional filter switching devices in terms of integration, accuracy, and maintainability, and has broad application prospects.

[0042] Preferably, the rotary drive component 31 is a drive motor.

[0043] Specifically, in this embodiment, compared with ordinary mechanical drive, the drive motor can provide more precise rotation angle control, thereby improving the positioning accuracy, stability and response speed of filter 36 switching.

[0044] More specifically, a high-precision stepper motor or brushless DC motor can be selected to achieve more stable, low-noise, and long-life operation, ensuring the precise positioning and repeatability of the filter 36.

[0045] Preferably, a PCB circuit board 8 is provided on the side of the bottom frame 1 for managing the power supply and signal transmission of the drive motor (rotation drive component 31) and the motor assembly 5. A pair of metal connecting pieces 9 are inserted into the motor housing and arranged opposite each other. One end of the metal connecting piece 9 is electrically connected to the motor coil, and the other end is electrically connected to the PCB circuit board 8 through a connecting wire. The metal connecting piece 9 is used to provide a stable electrical connection for the motor coil, simplify wiring, and improve assembly efficiency and reliability.

[0046] The two ends of the drive motor (rotary drive component 31) are electrically connected to the PCB circuit board 8 via connecting wires to ensure stable power supply and control signal transmission for the drive motor, avoid the problems of loose connection or breakage that may occur with traditional soldering connection methods, and improve the overall reliability of the system.

[0047] Preferably, the bottom frame 1 is made of a thermally conductive material (such as aluminum alloy), and the inner side of the PCB circuit board 8 is provided with a thermally conductive pad 10 made of a flexible material (such as silicone-based thermally conductive material). The two sides of the thermally conductive pad 10 are respectively attached to and abut against the PCB circuit board 8 and the bottom frame 1.

[0048] Specifically, in this embodiment, the bottom frame 1 is made of aluminum alloy or other high thermal conductivity composite materials, enabling the device to efficiently conduct and dissipate the internal heat (mainly from the motor assembly 5 and drive motor) during long-term operation, preventing overheating from affecting performance and lifespan. The function of the flexible material thermal pad 10 is:

[0049] Improve the heat dissipation capacity of PCB circuit board 8: conduct the heat generated by the electronic components on PCB circuit board 8 to the bottom frame 1.

[0050] Excellent filling and bonding: Utilizing its flexible properties, it effectively fills the tiny gaps and unevenness between the PCB circuit board 8 and the bottom frame 1, reducing contact thermal resistance and significantly improving heat dissipation efficiency.

[0051] The installation method of the thermal pad 10 ensures that its two sides are fully and tightly fitted against the PCB circuit board 8 and the bottom frame 1 respectively, forming an efficient heat conduction path and ensuring long-term stable operation of the system.

[0052] Preferred, Reference Figure 3 The second connector 7 includes an upper connecting portion 71 and a lower connecting portion 72 arranged in an alternating manner. The connection points of the upper connecting portion 71 and the lower connecting portion 72 with the synchronous shaft 34 are both semi-circular, which better encloses the synchronous shaft 34, ensuring smooth sliding and providing sufficient constraint to prevent misalignment or loosening, thus improving the accuracy of filter 36 switching. The lower end of the upper connecting portion 71 is slidably fitted onto the synchronous shaft 34, and the upper end of the lower connecting portion 72 is also slidably fitted onto the synchronous shaft 34.

[0053] Specifically, in this embodiment, the staggered semi-circular design allows the second connector 7 to form a stable sliding pair with the synchronous shaft 34. When the rotary drive component 31 drives the rotating shaft 32 to rotate, the spiral connecting bar 33 drives the filter bracket 35 to move through the first connector 6. The second connector 7, through a precise sliding connection with the synchronous shaft 34, strictly restricts the filter bracket 35 to move only in a straight line parallel to the synchronous shaft 34 (i.e., parallel to the rotating shaft 32), effectively avoiding any swaying or tilting that may occur during the movement of the filter bracket 35, thereby ensuring that the filter 36 is always precisely aligned.

[0054] Preferably, the integrated bracket 2 has buckles 11 on both sides of its bottom (the buckles 11 may have an elastic structure or be designed with fastening features), and slots 12 are provided on both sides of the bottom frame 1 (the size and shape of the slots 12 are designed to match the buckles 11 to achieve a stable and reliable fastening). The integrated bracket 2 is fastened to the slots 12 on both sides of the bottom frame 1 by the buckles 11 on both sides.

[0055] Specifically, in this embodiment, during installation, simply align the buckle 11 at the bottom of the integrated bracket 2 with the slots 12 on both sides of the bottom frame 1, and then press down. The buckle 11 will elastically deform and engage with the slots 12, locking in place. This achieves quick and secure assembly without the need for additional fasteners (such as screws), greatly improving assembly efficiency. When disassembly and maintenance are required, the buckle 11 can be elastically deformed and released by applying external force in a specific direction using a tool, allowing the integrated bracket 2 to detach from the slots 12.

[0056] This snap-fit ​​installation method makes the assembly and disassembly of the entire device faster and more efficient, making it particularly suitable for mass production line operations and on-site equipment maintenance. Meanwhile, the well-designed snap-fit ​​11 and slot 12 structure ensures a secure connection between the integrated bracket 2 and the bottom frame 1, effectively resisting vibrations or unexpected external forces during use, preventing loosening, and significantly improving the overall structural stability and reliability of the device.

[0057] Example 2, refer to Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a fan assembly 15 and a filter 16, which optimizes the heat dissipation and dust prevention performance of the device to improve long-term operational stability and reliability.

[0058] The bottom frame 1 has an air inlet 13 and an air outlet 14 on its side, and a fan assembly 15 is located near the air inlet 13. The fan assembly 15 includes a fan bracket 151, a fan motor 152, and fan blades 153. The fan motor 152 is fixed inside the fan bracket 151, and the fan blades 153 are fixedly sleeved on the output shaft of the fan motor 152. The fan motor 152 is used to drive the fan blades 153 to rotate so as to blow air towards the air inlet 13 (i.e., to force the introduction of external cold air into the device through the air inlet 13).

[0059] Preferably, both the air inlet 13 and the air outlet 14 are equipped with filters 16.

[0060] Working principle of Example 2:

[0061] To prevent the filter switcher and motor assembly 5 from overheating during long-term high-load operation, which would affect accuracy and lifespan, this embodiment designs an air inlet 13 and an air outlet 14 on the side of the bottom frame 1, and equips it with a fan assembly 15 to enhance airflow and achieve active and efficient heat dissipation.

[0062] Structural design: The bottom frame 1 has an air inlet 13 and an air outlet 14 on its side, forming an air convection channel. A fan assembly 15 is installed near the air inlet 13 to force external cold air into the device, flow through the heat-generating area (mainly the motor assembly 5, drive motor 31, and PCB circuit board 8), and push the hot air out of the air outlet 14.

[0063] Composition of fan assembly 15:

[0064] Fan bracket 151: Used to securely mount the fan assembly 15 onto the bottom frame 1 to ensure its stable operation.

[0065] Fan motor 152: Installed inside the fan bracket 151, it provides rotational power for the fan blades 153.

[0066] Fan blade 153: It is fixedly sleeved on the output shaft of fan motor 152. The motor drives the blade to rotate at high speed to generate airflow.

[0067] When the fan motor 152 starts, it drives the fan blades 153 to rotate, forcefully drawing outside air into the device through the air inlet 13. After the cold air flows through the motor assembly 5 and the filter switching assembly 3 (carrying away heat), it becomes hot air and is finally discharged from the air outlet 14 under the action of air pressure difference. Through this forced convection method, the temperature of key components inside the device is effectively reduced, ensuring that the equipment can maintain stable operation under high-intensity working environments or in confined spaces.

[0068] Both the air inlet 13 and the air outlet 14 are equipped with filters 16 to filter impurities such as dust, hair, fibers and particulate matter in the air and prevent them from entering the equipment.

[0069] To prevent dust from accumulating on the filter 36 and the lens (placed at the lens mounting port 4), and to avoid a decline in optical performance (such as reduced light transmittance, increased scattering, and blurred images).

[0070] To prevent dust from entering the motor assembly 5 or adhering to moving parts such as the spiral connecting bar 33 and the synchronous shaft 34, thus avoiding increased friction, wear, or jamming, which would affect motion accuracy and lifespan.

[0071] Filter 16 design: The filter 16 is removable (such as snap-on or magnetic type), which makes it easy for users to regularly clean accumulated dust or replace it, keeping the air inlet 13 and outlet 14 unobstructed. The filter 16 can be made of high-density fiber mesh, non-woven fabric or metal wire mesh, balancing good filtration effect with low ventilation resistance.

[0072] Beneficial effects of Example 2:

[0073] This embodiment incorporates an air inlet 13 and an air outlet 14 on the side of the bottom frame 1, along with a fan assembly 15 and a filter 16, forming a highly efficient ventilation, heat dissipation, and dust prevention system. This design:

[0074] Significantly improves heat dissipation: Active forced convection effectively reduces internal operating temperature, ensuring the long-term stability and lifespan of core components (motor, drive motor, PCB).

[0075] Effective dust prevention: Filter 16 blocks external contaminants from entering, protecting precision optical components (filter 36, lens) and motion mechanisms (spiral connecting bar 33, synchronous shaft 34, second connecting member 7) from contamination and wear, maintaining optical performance and mechanical precision.

[0076] Improved reliability: The passive heat dissipation of the thermally conductive frame (bottom frame 1) and thermally conductive pad 10, combined with the active heat dissipation of the fan assembly 15, constitutes a multi-level thermal management solution, which greatly improves the reliability and service life of the equipment in harsh environments.

[0077] This solution is particularly suitable for applications requiring high heat dissipation and cleanliness, such as precision optical instruments, industrial automated online testing equipment, and laboratory optical systems that operate for extended periods. It can meet the stringent requirements for high-precision optical switching and long-term operational stability.

[0078] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
