Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of door panels, specifically a transparent adjustable combined door panel and production process. BACKGROUND

[0002] The production process of door panels generally includes the following steps:

[0003] Raw material preparation: First, the raw materials for the door panel need to be prepared, usually using wood materials such as density board, shaving board or fiber board. These raw materials need to be cut and processed according to design requirements; Surface treatment: The surface of the door panel usually needs to be treated, such as skinning, sanding and repairing, etc. This step can make the door panel surface smooth and flat, and repair any defects or damage. Pattern engraving (optional): If the door panel needs to have patterns or patterns, a carving machine or numerical control engraving machine can be used for pattern engraving. This step is usually done on the surface of the door panel to create a decorative effect. Splicing and bonding: splice the cut wood boards and bond them together using glue or nails. This step needs to ensure that the door panel has sufficient strength and stability. Processing and shaping: further processing and shaping of the door panel through milling machines, drilling machines, etc. This may include corner trimming, slotting, drilling and shape cutting, etc. Painting and spraying: paint and spray the door panel to protect the wood material and give it the desired color and appearance. Painting can be done using brushing or spraying methods. Assembly and accessory installation: according to the needs, assemble the door panel with other components (such as door frame, hinges, locks, etc.) and install the necessary accessories. Inspection and quality control: during production, the door panel is inspected and quality controlled to ensure that it meets design requirements and relevant standards.

[0004] As the main component of the door, the door panel has the following main functions:

[0005] Isolation and protection: the door panel can isolate the indoor and outdoor environment, providing privacy and security. It can block noise, dust, wind, rain and other external factors from entering the room, while maintaining the temperature, humidity and other factors in the room within a suitable range. Safety and protection: as part of the door, the door panel can provide physical safety and protection. It can prevent theft, intrusion and protect personal and property safety. The material and structural design of the door panel determines its protection performance.

[0006] Decoration and aesthetics: the door panel plays a decorative role in indoor and outdoor spaces, affecting the overall aesthetics and style. Through different materials, patterns and color designs, the door panel can coordinate with the surrounding environment and highlight specific decorative intentions and style requirements.

[0007] Energy saving and heat insulation: reasonable selection of door panel material and structure design, can achieve the effect of energy saving and heat insulation. For example, the door panel with good thermal insulation performance can reduce the loss of energy, improve the temperature maintaining capacity of indoor, reduce the energy consumption of heating and refrigeration. Vibration reduction and noise reduction: the door panel can play the role of vibration reduction and noise reduction through its structure design and material selection. For example, adding sound insulation material or adopting multi-layer composite material structure in the door panel can reduce the transmission of sound and vibration, and provide a more quiet indoor environment

[0008] As a kind of space separating movable part, door is generally transparent or completely opaque, but with the continuous improvement of people's demand, door is only used as a kind of space isolation, sometimes it also needs to be used as a kind of reminding function, for example, in some cases, the door needs to change different light transmittance to remind the outside personnel whether there is a person in the space behind the door, and when the door is installed in some sunny position, sometimes it needs strong light, and sometimes it needs to weaken the intensity of light, so a kind of door panel capable of changing transparency is needed. SUMMARY

[0009] In order to make up for the shortcomings of the prior art, a kind of transparent adjustable combination door panel and production process are provided. The present application is mainly used to solve the problem that the transparency of the existing door body is not convenient to change.

[0010] The technical scheme adopted by the present application to solve its technical problems is: a kind of transparent adjustable combination door panel, including face plate and middle frame, the two sides of the middle frame are fixedly connected with face plate, the side of the middle frame is provided with lock hole, the face plate is made of transparent material, the middle part of the middle frame is hollow, the cavity formed by the face plate and the middle frame is filled with transparent medium, the transparent medium is mixed with magnetic particles, the lower part of the middle frame is provided with mixing component for mixing the magnetic particles and transparent medium, the side edge of the middle frame is provided with magnetic attraction component, the magnetic attraction component is used for adsorbing and fixing the magnetic particles, the top of the middle frame is respectively provided with filling hole and exhaust hole, the filling hole and exhaust hole are both screw connected with plug.

[0011] When the transparency of the door panel needs to be changed, the magnetic attraction part is removed from the magnetic particles in the cavity, and the magnetic particles fall. Then, the mixing part is driven to flow the transparent medium in the cavity, so as to drive the magnetic particles in the transparent medium to diffuse, so that the transparent medium becomes turbid, thereby reducing the transparency of the door panel. When the transparency of the door panel needs to be improved, the mixing part is stopped, and the magnetic particles slowly fall under the action of gravity due to the density of the magnetic particles being greater than the density of the transparent medium, thereby improving the transparency of the door panel. When the transparency of the door panel needs to be improved more quickly, the magnetic attraction part is controlled to work, so as to quickly attract the magnetic particles to one side close to the magnetic attraction part, thereby quickly improving the transparency of the door panel. The efficiency of changing the transparency is improved, and the practicality of the door panel is improved.

[0012] As a first preferred solution of the mixing part in the present solution, the mixing part comprises a spiral cylinder, the lower part of the middle frame is uniformly and spaced apart to provide mounting holes, the spiral cylinder is clamped and matched with the mounting holes on the middle frame, a top rod is slidably connected inside the spiral cylinder, a spiral groove is formed on the spiral cylinder, a limiting protrusion is fixedly connected on the top rod, the limiting protrusion passes through the spiral groove and is slidably connected with the spiral groove, the upper end of the top rod extends to the inside of the cavity through the middle frame, a impeller is fixedly connected to the upper end of the top rod, a baffle is fixedly connected to the top rod inside the mounting hole, a reset spring is sleeved on the top rod, one end of the reset spring is fixedly connected with the baffle, and the other end is abutted with the top of the mounting hole, and the other end of the top rod is provided as an inclined surface.

[0013] When the door is closed, the lower part of the top rod abuts on the step on the ground. Since the top rod is provided as an inclined surface, the top rod is pushed to move in the vertical direction as the door body is gradually closed. The limiting column on the top rod is located inside the spiral groove, so that the top rod rotates while moving upward. The rotation of the top rod drives the impeller to rotate, which stirs the transparent medium in the cavity, so that the magnetic particles in the cavity are driven and uniformly mixed, thereby reducing the transparency of the door body. Since the transparency is reduced in this way, the stirring action is combined with the action of closing the door, thereby reducing the additional step of adjusting the transparency, so that the convenience of adjusting the transparency is improved, and the convenience of using the door body is improved. At the same time, no additional power supply is needed during the adjustment, so that the use cost of the door body is reduced.

[0014] Preferably, the particle size of the magnetic particles includes three specifications of 1-2mm, 3-4mm and 4-5mm.

[0015] After the internal magnetic particles are mixed, the magnetic particles gradually settle under the action of gravity, thereby realizing the change of transparency; and in the present scheme, the internal magnetic particles are arranged in different specifications, and thus in the settling process of the magnetic particles, due to the inconsistent gravity of the magnetic particles, some particles settle quickly and some slowly, thereby different transparency stages appear in the settling process of the magnetic particles, so as to realize the change of transparency in more ways, so as to present different visual effects, thereby realizing the diversity of the door plate in use, and different settling stages can present different time stages, so as to increase the playability of the door plate, thereby improving the use scenarios of the door plate.

[0017] By arranging the magnetic piece in the sliding groove, when the transparency of the door body is reduced, the hand screw bolt is rotated to move the hand screw bolt outward, thereby moving the wedge block two outward, and under the action of the limiting spring, the wedge block one moves outward, thereby moving the magnetic piece away from the cavity, so as to increase the magnetic attraction force between the magnetic piece and the internal magnetic particles, thereby the movement of the magnetic particles in the cavity is not affected by the magnetic force; when the transparency of the door body needs to be improved, the hand screw bolt is reversely rotated, so as to move the wedge block two into the sliding groove, thereby pushing the wedge block one to move downward, and thereby moving the magnetic piece close to the cavity, so as to increase the adsorption force on the internal magnetic particles, and with the flow of the internal medium, the magnetic particles suspended in the medium are reduced more quickly, so as to improve the transparency more quickly; by adjusting the distance between the magnetic piece and the magnetic particles, the adsorption force on the magnetic particles is adjusted, thereby realizing the speed of adjusting the transparency; the adjustment is realized by the above mechanical structure, so as to ensure that the door body can still be normally used in the case of power failure, improve the application scenarios of the door body, and reduce the use cost of the door body.

[0018] As a second preferred scheme of the mixing component in the present scheme, the mixing component comprises a motor, the bottom of the middle frame is provided with grooves, the grooves are uniformly and fixedly connected with the motor, the output shaft of the motor extends to the inside of the cavity through the middle frame, and the end of the output shaft of the motor is fixedly connected with an impeller.

[0019] The rotation of the motor drives the rotation of the impeller, the time of the rotation of the impeller is more durable, the opacity is maintained for a longer time, the more diversified use is adapted, the mixing degree of the magnetic particles in the transparent medium is more uniform through the driving of the motor, the consistency of the transparency is realized, and the appearance of the door body is improved. Meanwhile, the movement of the medium in the door body is smoother through the rotation of the motor, the operation of the door body in a colder environment is adapted, and the adaptability of the door body is improved.

[0022] Preferably, the magnetic particles are multi-angled thorn spherical.

[0023] The magnetic particles are set to be multi-angled thorn spherical, when the magnetic particles are uniformly mixed in the cavity, the light entering the cavity contacts the magnetic particles and is reflected and refracted at multiple angles, the light can pass through the door body well, the protection property of the door is ensured, the mutual embedding relationship between the magnetic particles is increased through the multi-angled thorn spherical structure, a better stable state is maintained after mixing, the local transparency is reduced, and the uniformity of the transparency of the door body is improved.

[0027] By arranging the arc-shaped plates on both sides of the impeller, when the impeller agitates the transparent medium in the cavity, the flow direction of the transparent medium is guided by the impact of the transparent medium on the arc-shaped plates, so that the flow direction of the medium is more extensive, the flow property of the internal medium is increased, the uniformity of the mixed magnetic powder is improved, the consistency of the transparency of the door body is improved, the quality of the transparency adjustment is improved, and the quality of the door body is improved.

[0028] A production process of a combined door panel, comprising the following steps:

[0029] S1: the raw materials are cut according to the designed size, and the cut middle frame is engraved to process the corresponding mounting positions of each component;

[0030] S2: the surface of the middle frame is roughened, then the sealing ring is installed in the ring groove of the middle frame, the adhesive glue is coated on the surface of one side of the middle frame, the panel on the side is adhered to the middle frame, then a pressure of not less than 10KN is applied thereon for 10 minutes;

[0031] S3: whether there is a glue defect in the adhesive position of the middle frame and the panel is checked, if there is a glue defect, the glue is repaired by drilling a hole in the panel, the glue repairing surface is flush with the surface of the panel, and the glue is cured after standing;

[0032] S4: then the adhered panel and the middle frame are placed horizontally, then water is filled in the middle part of the middle frame, and whether there is water seepage at the connection between the middle frame and the panel is observed, if there is water seepage, a hole is drilled in the panel to repair the water seepage;

[0035] S7: Fill the inside of the middle frame with magnetic particles, then apply glue to the other side of the middle frame and attach the panel on that side. Then apply a pressure of not less than 15KN for not less than 20 minutes. Then seal the vent hole and fill the cavity with air from the filling inlet. At the same time, observe the air tightness of the cavity. If there is any leakage, drill a hole in the panel to repair it. After the repair is completed, repeat the air tightness check until the air tightness of the cavity meets the standard.

[0036] S8: Once the airtightness of the cavity meets the standard, fill the cavity with a transparent medium through the filling inlet until the transparent medium is discharged from the exhaust port. Then seal the filling inlet and the exhaust port.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. In this invention, when it is necessary to change the transparency of the door panel, the magnetic attraction force of the magnetic components on the internal magnetic particles is first removed, causing the magnetic particles to fall. Then, the mixing component drives the flow of the transparent medium inside the cavity, thereby causing the internal magnetic particles to diffuse in the transparent medium, making the transparent medium turbid, thus reducing the transparency of the door panel. When it is necessary to increase the transparency of the door panel, the stirring of the mixing component can be stopped. Since the density of the magnetic particles is greater than the density of the transparent medium, the magnetic particles will slowly fall under the action of gravity, thus increasing the transparency of the door panel. When it is necessary to increase the transparency of the door panel more quickly, the magnetic attraction component can be controlled to apply a magnetic attraction force to the magnetic particles inside the cavity, quickly attracting the magnetic particles to the side close to the magnetic attraction component, thus rapidly increasing the transparency of the door panel. This improves the efficiency of transparency change and enhances the practicality of the door panel.

[0039] 2. In this invention, when the door is closed, the lower part of the push rod abuts against the step on the ground. Because it is designed as an inclined surface, as the door gradually closes, it pushes the push rod to move vertically. The limiting post on the push rod is located inside the spiral groove. During the upward movement of the push rod, it rotates simultaneously. This rotation causes the impeller to rotate, which in turn agitates the transparent medium inside the cavity. This agitates the magnetic particles inside the cavity, causing them to mix evenly, thus reducing the transparency of the door. Since this method of reducing transparency is used, considering that the actual need for transparency reduction is after the door is closed, the agitation action is combined with the closing action, reducing the need for additional transparency adjustment steps and thus improving the convenience of transparency adjustment. This also improves the ease of use of the door. Furthermore, no additional power supply is required during adjustment, thus reducing the operating cost of the door.

[0040] 3. In the present application, by setting the internal magnetic particles to different specifications, and then in the process of settling of the magnetic particles, due to the inconsistent gravity of the magnetic particles, some particles will settle quickly, and some will settle slowly, and then different transparency stages will appear in the process of settling of the magnetic particles, so as to realize more kinds of transparency changes, so as to present different visual effects, and then the diversity of the door plate can be realized, and different settling stages can present different time stages, so as to increase the playability of the door plate, and then the use scene of the door plate is improved.

[0041] 4. In the present application, by arranging the magnetic part in the chute, when the transparency of the door body is reduced, the hand screw bolt is moved outwardly from the door body by rotating the hand screw bolt, and then the wedge block two is moved outwardly, and then the wedge block one is moved outwardly under the action of the limiting spring, and then the magnetic part is moved away from the cavity, so as to increase the magnetic attraction between the magnetic part and the internal magnetic particles, and then the movement of the magnetic particles in the cavity is not affected by the magnetic force; when the transparency of the door body needs to be improved, the hand screw bolt is reversely rotated, so that the wedge block two is moved into the slide, and then the wedge block one is pushed downward, and then the magnetic part is moved towards the cavity, so as to increase the adsorption force on the internal magnetic particles, and then the magnetic particles suspended in the medium are reduced more quickly with the flow of the internal medium, so as to realize faster improvement of the transparency; by adjusting the distance between the magnetic part and the magnetic particles, the adsorption force on the magnetic particles is adjusted, and then the speed of adjusting the transparency is realized; the adjustment is realized by the above mechanical structure, so as to ensure that the door body can still be normally used in the case of power failure, the application scene of the door body is improved, and the use cost of the door body is reduced.

DETAILED DESCRIPTION

[0052] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application will be further described below in combination with specific embodiments.

[0053] As Figures 1 to 3 shown, a transparent adjustable combined door panel, comprising a panel 1 and a middle frame 2; the two sides of the middle frame 2 are respectively fixedly connected with the panel 1; one side of the middle frame 2 is provided with a lock hole; the panel 1 is made of transparent material; the middle part of the middle frame 2 is hollow; the cavity formed by the panel 1 and the middle frame 2 is filled with transparent medium; the inside of the transparent medium is mixed with magnetic particles 3; the lower part of the middle frame is provided with a mixing component for mixing the magnetic particles 3 with the transparent medium; the side edge of the middle frame 2 is provided with a magnetic attraction component; the magnetic attraction component is used for adsorbing and fixing the magnetic particles 3; the top part of the middle frame 2 is respectively provided with a filling hole 4 and an exhaust hole 5; the filling hole 4 and the exhaust hole 5 are respectively threadedly connected with plugs 6.

[0054] When working, the door is an active component for separating space, which is mostly transparent or completely opaque, but as people's demand continues to improve, the door only has the function of separating space, and sometimes also needs to have the function of reminding the user, for example, the door needs to change different light transmittance in some cases to remind the outside personnel whether there is a person in the space behind the door, and when the door is installed in some sunny positions, sometimes strong light is needed, and sometimes the intensity of light needs to be weakened, so a door panel capable of changing light transmittance is needed.

[0055] When the transparency of the door plate needs to be changed, the magnetic attraction part is removed from the magnetic particles 3 in the cavity, and the magnetic particles 3 fall. Then, the mixing part is driven to flow the transparent medium in the cavity, so that the magnetic particles 3 in the cavity are diffused in the transparent medium, and the transparent medium becomes turbid, so that the transparency of the door plate is reduced. When the transparency of the door plate needs to be improved, the mixing part is stopped, and the magnetic particles 3 slowly fall under the action of gravity, so that the transparency of the door plate is improved. When the transparency of the door plate needs to be improved more quickly, the magnetic attraction part is controlled to work, so that the magnetic particles 3 are quickly attracted to one side close to the magnetic attraction part, so that the transparency of the door plate is quickly improved. Therefore, the efficiency of changing the transparency is improved, and the practicability of the door plate is improved.

[0056] The transparent medium can be transparent glue or silicon oil, and the kinematic viscosity of the transparent medium is between 100 centistokes and 250 centistokes. The kinematic viscosity is an index for measuring the internal resistance of the fluid, and describes the difficulty of the fluid flowing under the action of external force. The kinematic viscosity can be used to measure the flow characteristics of the liquid under shear stress. Therefore, by controlling the kinematic viscosity, the magnetic particles 3 can be suspended in the transparent medium for a longer time, so that the transparency can be maintained for a longer time under the condition of natural falling after mixing. At the same time, the temperature stability of the silicon oil is relatively good, and the door plate can adapt to more variable environmental temperatures, so that the use effect of the door plate in different seasons is ensured.

[0057] Secondly, the connection relationship between the door body and the middle frame 2 is fixed connection. In order to ensure the sealing performance and the particularity of the material, the panel 1 can be made of transparent acrylic material, and the middle frame 2 can be made of high molecular plastic material. The middle frame 2 and the panel 1 can be bonded by glue. The surface of the middle frame 2 is ground at the bonding surface to increase the precision of the connection. A ring groove is formed in the middle frame 2, and a sealing ring 24 is filled in the ring groove. After the middle frame 2 and the panel 1 are connected, the sealing ring 24 is compressed to realize the sealing performance of the panel 1 and the middle frame 2, and the reliability of the door body is improved.

[0058] Because the door body is filled with medium, the mass of the door body is large, so the inner edge of the middle frame 2 is rounded, so as to avoid the stress concentration at the inner corner of the middle frame 2, and cause damage to the door body. Therefore, the use structure strength of the door body is increased, and the service life of the door body is improved.

[0059] As the first embodiment of the mixing part in the application, as shown in Figure 4And Figure 7 As shown, the mixing component includes a spiral cylinder 7; the lower part of the middle frame 2 is uniformly spaced apart to provide a mounting hole; the spiral cylinder 7 is clamped with the mounting hole on the middle frame 2; the inside of the spiral cylinder 7 is slidingly connected with a top rod 8; the spiral cylinder 7 is provided with a spiral groove 9; the top rod 8 is fixedly connected with a limiting protrusion 10; the limiting protrusion 10 passes through the spiral groove 9 and is slidingly connected with the spiral groove 9; the upper end of the top rod 8 extends to the inside of the cavity through the middle frame 2; the upper end of the top rod 8 is fixedly connected with an impeller 11; the inside of the mounting hole is fixedly connected with a baffle 13; the top rod 8 is sleeved with a reset spring 12; one end of the reset spring 12 is fixedly connected with the baffle 13, and the other end is abutted with the top of the mounting hole; the other end of the top rod 8 is provided as an inclined surface.

[0060] In work, generally when it is needed to reduce the transparency of the door body, after the door body is closed, in this scheme, the top rod 8 is arranged at the lower part of the middle frame 2, and the lower part of the top rod 8 is provided as an inclined surface, and a step is arranged at the ground under the lower part of the door body in order to increase the sealing performance of the door during installation; in this scheme, when the door is closed, the lower part of the top rod 8 abuts against the step on the ground, and since it is provided as an inclined surface, as the door body is gradually closed, the top rod 8 is pushed to move in the vertical direction, and since the limiting column on the top rod 8 is located inside the spiral groove 9, the top rod 8 is rotated while moving upward, and since the top rod 8 is rotated, the impeller 11 is also rotated, and as the impeller 11 is rotated, the transparent medium inside the cavity is stirred, and the magnetic particles 3 inside are driven and uniformly mixed in the cavity, so as to reduce the transparency of the door body; since the transparency is reduced in this form, considering that the requirement of reducing the transparency in the actual use scenario is to close the door, the stirring action is combined with the action of closing the door, so as to reduce the step of additionally adjusting the transparency, so as to realize the convenience of adjusting the transparency, and improve the convenience of using the door body; and since no additional power supply is needed during the adjustment, the use cost of the door body is reduced.

[0061] Since the number of rotations of the impeller 11 is limited during the closing of the door, the ability of the impeller 11 to stir the transparent medium is relatively weak, and therefore when the mixing is performed in this form, the thickness of the cavity is reduced, so as to reduce the amount of the transparent medium inside the cavity, and according to the height of the step under the door body, the thickness of the cavity is set to be not more than 6 mm.

[0062] The particle size of the magnetic particles 3 includes three specifications of 1-2 mm, 3-4 mm and 4-5 mm.

[0063] During operation, after the internal magnetic particles 3 are mixed evenly, they gradually settle under the influence of gravity, thereby changing the transparency. In this solution, by setting the internal magnetic particles 3 to different specifications, during the settling process, due to the inconsistent gravity of the magnetic particles 3, some particles settle quickly while others settle slowly. This results in different transparency stages during the settling process of the magnetic particles 3, achieving a wider variety of transparency variations and presenting different visual effects. This allows for diverse uses of the door panel, and different settling stages can represent different time periods, thus increasing the playability of the door panel and expanding its application scenarios.

[0064] As a first embodiment of the magnetic attraction component in this invention; such as Figure 3 As shown, the magnetic attraction component includes a magnetic element 14; a sliding groove is provided on one side of the middle frame 2; the magnetic element 14 is slidably connected in the sliding groove; a limiting spring 15 is fixedly connected to the side of the magnetic element 14 near the cavity; one end of the limiting spring 15 abuts against the bottom of the sliding groove; a wedge block 16 is fixedly connected to the side of the magnetic element 14 away from the middle frame 2; a hand-tightening bolt 18 is threadedly connected to the side of the middle frame 2; the hand-tightening bolt 18 passes through the panel 1 and is threadedly connected to the middle frame 2 in sequence, and a wedge block 17 is fixedly connected to the end of the hand-tightening bolt 18 located in the sliding groove; the wedge block 16 abuts against the wedge block 17.

[0065] During operation, a magnetic component 14 is installed inside the slide rail. When reducing the transparency of the door, the hand-tightening bolt 18 is rotated, causing it to move outward. This moves the second wedge 17 outward, and under the action of the limiting spring 15, the first wedge 16 moves outward. This causes the magnetic component 14 to move away from the cavity, increasing the magnetic attraction between the magnetic component 14 and the internal magnetic particles 3. This ensures that the movement of the magnetic particles 3 inside the cavity is not affected by the magnetic force. When it is necessary to increase the transparency of the door, the hand-tightening bolt 18 is rotated in the opposite direction, moving the second wedge 17 inward into the slide rail. This pushes the wedge 16 downwards, causing the magnetic component 14 to move closer to the cavity, thereby increasing the attraction force on the internal magnetic particles 3. With the flow of the internal medium, this allows for a faster reduction of the magnetic particles 3 suspended in the medium, thus achieving a faster increase in transparency. By adjusting the distance between the magnetic component 14 and the magnetic particles 3, the attraction force on the magnetic particles 3 can be adjusted, thereby adjusting the speed of transparency adjustment. This adjustment is achieved through the above mechanical structure, ensuring that the door can still be used normally in the event of a power outage, thus expanding the application scenarios of the door and reducing its operating costs.

[0066] As a second embodiment of the mixing component in the application; as Figure 6 As shown in the figure, the mixing component includes a motor 19; the bottom of the middle frame 2 is provided with a groove; the groove is uniformly and fixedly connected with the motor 19; the output shaft of the motor 19 extends to the inside of the cavity through the middle frame 2; the end of the output shaft of the motor 19 is fixedly connected with the impeller 11.

[0067] In operation, the rotation of the motor 19 drives the rotation of the impeller 11, which can last longer, thereby maintaining the opacity for a longer period of time, thereby adapting to more diversified use. Meanwhile, the driving of the motor 19 can make the mixing of the magnetic particles 3 in the transparent medium more uniform, thereby achieving more consistent transparency and improving the aesthetic appearance of the door body. Meanwhile, the rotation of the motor 19 can make the movement of the medium inside the door body more smooth, thereby adapting to the operation of the door body in a colder environment, thereby improving the adaptability of the door body.

[0068] The above-mentioned motor 19 is equipped with a controller and is electrically connected with an external power supply box to realize the control of the motor 19.

[0069] As a second embodiment of the magnetic attraction component in the application; as Figure 6 As shown in the figure, the magnetic attraction component includes an electromagnet 20; one side of the middle frame 2 is provided with a chute; the chute is fixedly connected with the electromagnet 20; one side of the electromagnet 20 is provided with a current regulator 21; the current regulator 21 is electrically connected with the electromagnet 20; the electromagnet 20 and the current regulator are electrically connected with an external power supply.

[0070] In operation, Ampere's law indicates that the magnetic field generated by the current through a conductor is proportional to the current. Specifically, when the current passes through the coil of the electromagnet 20, a magnetic field is generated. The strength of this magnetic field depends on the size of the current. When the current increases, the strength of the magnetic field also increases; when the current decreases or disappears, the strength of the magnetic field also decreases or disappears.

[0071] The strength of the magnetic field generated by the electromagnet 20 can be calculated using Ampere's loop theorem. According to Ampere's loop theorem, the total magnetic field strength through the coil of the electromagnet 20 is equal to the sum of the currents on all closed paths around the coil. Therefore, increasing the size of the current will increase the strength of the magnetic field.

[0072] Therefore, in the present solution, the size of the magnetic attraction force can be controlled by controlling the size of the current. When the transparency needs to be changed, the user controls the adsorption force of the electromagnet 20 to achieve the adsorption of magnetic particles 3 of different particle sizes. In this way, the number of active magnetic particles 3 in the cavity can be reduced or increased, thereby achieving the effect of changing the transparency of the door body. By controlling the size of the current to control the magnetic attraction force, faster adjustment can be achieved, and more accurate adjustment can be achieved, thereby achieving fast and accurate transparency adjustment. In this way, the simplicity of door transparency adjustment is improved.

[0073] The current regulator 21 described above is a adjustable current source that can provide adjustable current output as needed. Adjustable current source can be applied in many scenarios, such as laboratory research, electronic device testing and industrial production, etc. It is usually composed of a constant current circuit, a current control element and an adjustment circuit. By adjusting the parameters of the current control element, the adjustment of the current output can be realized

[0074] As shown in Figure 8 , the magnetic particles 3 are multi-angled thorn spherical.

[0075] When working, by setting the magnetic particles 3 as multi-angled thorn spherical, when the magnetic particles 3 are mixed in the cavity, the light entering the cavity will be reflected and refracted at multiple angles after contacting the magnetic particles 3, thereby better placing the light through the door body, thereby ensuring that the door body is in an opaque state when the magnetic particles 3 are mixed, thereby ensuring the protection characteristics of the door. At the same time, by setting the multi-angled thorn spherical, the mutual embedding relationship between the magnetic particles 3 can be increased, thereby maintaining a better stable state after mixing, reducing the occurrence of local transparency; thereby improving the uniformity of the transparency of the door body.

[0076] As shown in Figure 4 , the upper inner side of the middle frame 2 is fixedly connected with a light source 22; the light source 22 is electrically connected with an external power supply.

[0077] When working, since the internal magnetic particles 3 are multi-angled thorn spherical structures, when the light shines on the magnetic particles 3, it will produce multiple angle reflections, thereby increasing the brightness on the door body, making the door body more beautiful, thereby improving the ornamental value of the door body; to improve the use experience of the door body.

[0078] As shown in Figures 2 to 6 , the opposite sides of the panel 1 are uniformly and spacedly provided with arc-shaped plates 23; the arc-shaped plates 23 are fixedly connected with the panel 1; the arc-shaped plates 23 are arranged on both sides of the impeller 11.

[0079] In operation, by setting the arc-shaped plate 23 on both sides of the impeller 11, and further when the impeller 11 agitates the transparent medium in the cavity, the transparent medium hits the arc-shaped plate 23 to guide the flow direction of the transparent medium, so that the impeller 11 can make the medium flow in a more extensive direction, thereby increasing the flow of the internal medium, and further improving the uniformity of the mixed magnetic powder, and further improving the consistency of the transparency of the door body, and further improving the quality of the transparency adjustment, and further improving the quality of the door body.

[0080] For the above two embodiments of the mixing assembly and the magnetic assembly, in actual products, they can be randomly combined and used, or multiple forms are considered for use to achieve better mixing effect and magnetic purification effect.

[0082] S1: The raw materials are cut according to the designed size, and the middle frame 2 after cutting is engraved to process the corresponding installation position of each component;

[0083] S2: The surface of the middle frame 2 is roughened, then the sealing ring 24 is installed inside the ring groove on the middle frame 2, the surface on one side of the middle frame 2 is coated with adhesive, and the panel 1 on that side is adhered to the middle frame 2, then a pressure of not less than 10KN is applied for 10 minutes;

[0084] S3: Check whether there is a glue defect in the adhesive position of the middle frame 2 and the panel 1, if there is a glue defect, drill a hole in the panel 1 to supplement the glue, the supplemented glue surface is flush with the surface of the panel 1, and the glue is cured after standing;

[0085] S4: Then place the adhered panel 1 and middle frame 2 horizontally, then fill water in the middle of the middle frame 2, and observe whether there is water seepage at the connection between the middle frame 2 and the panel 1, if there is water seepage, drill a hole in the panel 1 to repair the water seepage by supplementing the glue;

[0086] S5: Remove the water in the middle frame 2, then vibrate the middle frame 2 and the adhered panel 1 for 10 minutes, then repeat the above S4 step;

[0087] S6: After completing the S5 step, install the mixing component, the magnetic component and the light source 22, and test the running condition of the mixing component and the magnetic component; if it is not smooth, repair it;

[0088] S7: and fill the middle frame 2 inside with magnetic particles 3, then coat the other side of the middle frame 2 with glue, and adhere the panel 1 on this side, then apply a pressure of no less than 15KN for no less than 20 minutes, then plug the exhaust hole 5, and fill the cavity with air from the filling inlet, while observing the air tightness of the cavity, if there is air leakage, drill a hole in the panel 1 for repair, and after repair, repeat the air tightness check until the cavity air tightness meets the standard;

[0089] S8: when the cavity air tightness meets the standard, fill the cavity with transparent medium through the filling inlet until the transparent medium is discharged from the exhaust hole 5, then plug the filling inlet and the exhaust hole 5.

[0090] When working, when the transparency of the door panel needs to be changed, the magnetic attraction part is removed from the magnetic particles 3 inside, which will make the magnetic particles 3 fall, then the mixing part is set to drive the flow of the transparent medium inside the cavity, so as to drive the magnetic particles 3 inside to diffuse in the transparent medium, so as to make the transparent medium become turbid, so as to reduce the transparency of the door panel, when the transparency of the door panel needs to be improved, the mixing part can be stopped, because the density of the magnetic particles 3 is greater than the density of the transparent medium, under the action of gravity, the magnetic particles 3 will slowly fall, so as to realize the improvement of the transparency of the door panel; when the transparency of the door panel needs to be improved more quickly, the magnetic attraction part can be controlled to work, so as to exert magnetic attraction force on the magnetic particles 3 inside the cavity, so as to quickly attract the magnetic particles 3 to one side close to the magnetic attraction part, so as to quickly improve the transparency of the door panel; thereby improving the efficiency of the change of the transparency; thereby improving the practicability of the door panel.
