Description

Refrigerated and frozen storage device with magnetic field module

[0001] This application is based on and claims priority to Chinese Patent Application No. 202410961679.4, filed on July 17, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cold storage technology, and in particular to a cold storage device with a magnetic field module. Background Technology

[0003] The preservation and storage performance of household refrigeration and freezing equipment such as refrigerators has become an important indicator for evaluating the performance of such equipment. Fresh meat, fish, and shrimp are prone to loss of juices during storage, leading to a decline in taste and a darkening of color.

[0004] Traditional refrigerated and frozen storage devices primarily rely on precise temperature control and accelerated refrigeration or lowering of storage temperature (deep freezing) to improve food preservation. These temperature-based preservation methods are costly and complex to control. In recent years, those skilled in the art have actively explored other preservation technologies.

[0005] Current research has found that magnetic fields also have a certain impact on the preservation and storage of food. A magnetic field is a physical field with energy that affects the bonding and breaking of hydrogen bonds in water molecules. It promotes the breaking of hydrogen bonds, causing water molecules to clump together into larger clusters, altering the clustering phenomenon and forming smaller water molecule clusters, or even individual water molecules. Under the influence of a magnetic field, small water molecule clusters or ice nuclei formed by individual water molecules are less likely to aggregate and grow into large ice crystals, appearing as micro-ice crystals. This not only accelerates the phase transition stage of the freezing process but also reduces the damage to food cells caused by ice crystals. Therefore, introducing a suitable magnetic field into refrigerated and frozen storage devices can help improve the preservation and storage of food.

[0006] However, the related technology places the magnetic field components inside the refrigeration and freezing equipment for a long time, which makes them susceptible to the effects of low temperature, humidity, food residue, etc. The surface is easily corroded and damaged, resulting in a decrease in the reliability of the magnetic field components.

[0007] Any prior art mentioned in the specification does not imply confirmation or suggestion that such prior art constitutes part of the general common knowledge in any jurisdiction, or that it can be reasonably expected that such prior art will be understood, regarded as relevant and / or combined with other prior art by a person skilled in the art. Summary of the Invention

[0008] In view of the above problems, this application proposes a refrigerated and frozen storage device with a magnetic field module that at least partially solves the above problems and improves the reliability of the magnetic field component.

[0009] A further objective of this application is to ensure that the magnetic field module is installed correctly, and to ensure that the magnetic pole direction and the position of the magnetic source are correct.

[0010] Another further objective of this application is to ensure that the magnetic source component and the magnetic conductive plate in the magnetic field module are in close contact, thereby improving the preservation effect of the magnetic field.

[0011] This application provides a refrigerated and frozen storage device with a magnetic field module, comprising:

[0012] The container has a defined storage compartment inside;

[0013] The first magnetic field module and the second magnetic field module are arranged at intervals relative to each other inside the storage room, thereby forming a fresh-keeping storage space with a magnetic field between the first magnetic field module and the second magnetic field module.

[0020] The first magnetic field module is located above the second magnetic field module.

[0021] Optionally, the enclosure includes: a first housing and a second housing disposed on the first housing, the first housing and the second housing together defining the installation space;

[0022] The first housing and the second housing are provided with a plurality of mutually cooperating peripheral connecting parts, and the middle part of the first housing and the middle part of the second housing are respectively provided with mutually cooperating middle limiting structures.

[0023] Optionally, the first magnetic field module and the second magnetic field module are respectively configured as square plates;

[0024] The peripheral connecting parts are snap-fit ​​connection structures and / or screw connection structures.

[0025] Optionally, the position of the central limiting structure of the first magnetic field module relative to the geometric center of the first magnetic field module is different from the position of the central limiting structure of the second magnetic field module relative to the geometric center of the second magnetic field module; and,

[0026] The magnetic source component and the magnetic guide plate are provided with through holes at the positions corresponding to the central limiting structure, so that the central limiting structure can pass through.

[0027] Optionally, each central limiting structure includes:

[0028] The first limiting part is disposed on the inner surface of the first housing and extends toward the second housing;

[0029] The second limiting part is disposed on the inner surface of the second housing at a position opposite to the first limiting part, and the first limiting part and the second limiting part are connected by a snap-fit ​​structure to limit the distance between the inner surface of the first housing and the inner surface of the second housing.

[0030] Optionally, each central limiting structure includes:

[0031] Screw posts are disposed on the inner surface of the first housing or the second housing;

[0032] A connecting screw is attached to the screw post from the opposite side to the screw post to define the distance between the inner surface of the first housing and the inner surface of the second housing.

[0033] Optionally, the inner surfaces of the first housing and the inner surfaces of the second housing are respectively provided with supporting ribs in the areas opposite to the magnetic source or the magnetic guide plate. The supporting ribs are configured to abut against the magnetic source or the magnetic guide plate, so that the magnetic guide plate and the magnetic source are in close contact.

[0034] Optionally, the support ribs are configured as annular rings surrounding the central limiting structure, and there are multiple support ribs. The minimum distance between adjacent support ribs is set to be less than the sum of the thicknesses of the magnetic guide plate and the magnetic source component.

[0035] The width of the top surface of the support rib is set to be greater than the sum of the thicknesses of the magnetic guide plate and the magnetic source component.

[0036] Optionally, the housing is provided with guide and fixing structures on the lateral sides of the first magnetic field module and the second magnetic field module respectively, and the position and / or shape and / or size of the guide and fixing structures of the first magnetic field module and the second magnetic field module are set to be different;

[0037] The first magnetic field module and the second magnetic field module are equipped with matching structures at their respective positions with the corresponding guide fixing structures to ensure the position of the first magnetic field module and the second magnetic field module relative to the storage room.

[0038] The beneficial effects of this application are as follows:

[0039] The refrigerated and frozen storage device with a magnetic field module provided in this application comprises a first magnetic field module and a second magnetic field module, which are arranged relatively spaced apart inside the storage compartment. This creates a magnetic field-based preservation storage space between the first and second magnetic field modules, applying magnetic field preservation technology to household refrigerated and frozen storage devices such as refrigerators. By applying a magnetic field that meets the requirements of a preservation environment, the preservation effect of stored food and other items is improved. The first and second magnetic field modules utilize encapsulated shells to seal and protect the internal magnetic source components and magnetic conductive plates, preventing them from being exposed to the preservation storage space and thus avoiding contamination or corrosion. This extends the service life of the magnetic field components and improves their reliability.

[0040] The refrigerated and frozen storage device with a magnetic field module disclosed in this application has an encapsulation shell configured to bring the magnetic source component closer to the storage space relative to the magnetic guide plate, ensuring the accurate direction of the magnetic field of the magnetic source component. Addressing the characteristic that magnetic field strength gradually decreases with distance, the encapsulation shell optimizes the installation space structure to ensure the magnetic source component is closer to the storage space, fully utilizing the magnetic field released by the magnetic source component.

[0041] The refrigerated and frozen storage device with a magnetic field module of this application optimizes the limiting structure of the packaging shell of the first magnetic field module and the second magnetic field module, and sets a peripheral connecting part and a central limiting structure to avoid deformation of the packaging shell, ensure that the magnetic source and the magnetic plate can be reliably located in the set position, avoid the occurrence of local voids, ensure uniform distribution of the magnetic field, and reduce the loss of magnetic field strength.

[0042] The refrigerated and frozen storage device with a magnetic field module of this application also provides support ribs on the inner surface of the first shell and the inner surface of the second shell in the areas opposite to the magnetic source or magnetic guide plate. The support ribs abut against the magnetic source or magnetic guide plate, so that the magnetic guide plate and the magnetic source are tightly fitted, which further improves the structural stability of the encapsulated shell.

[0043] The above and other objects, advantages and features of this application will become more apparent to those skilled in the art from the following detailed description of specific embodiments of this application in conjunction with the accompanying drawings.

[0044] The term “comprise” as used herein, and variations thereof such as “comprises”, “comprised”, “comprising”, “including”, and “containing”, do not exclude other features, components, elements, or steps unless the context clearly requires otherwise. Attached Figure Description

[0061] Those skilled in the art should understand that the embodiments described below are merely a part of the embodiments of this application, and not all of the embodiments of this application. These partial embodiments are intended to explain the technical principles of this application and are not intended to limit the scope of protection of this application. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort should still fall within the scope of protection of this application.

[0062] In the description of this embodiment, it should be understood that the terms "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. For example, unless otherwise explicitly defined, for a refrigerator-type refrigeration and freezing device, the direction of the cabinet towards the door is front, the direction relative to the door towards the cabinet is rear, the direction towards the supporting ground is down, and the direction opposite to the ground is up.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] Furthermore, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" in this application should be interpreted broadly. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0065] This embodiment provides a refrigerated and frozen storage device with a magnetic field module. This refrigerated and frozen device is a storage device including a refrigeration system, one embodiment of which is a refrigerator. The refrigeration system can be a common compression refrigeration system, which provides cooling to the storage compartment through, for example, direct cooling and / or air cooling, to maintain the desired storage temperature in the storage compartment.

[0066] The refrigerated and frozen storage device 10 of this embodiment generally includes a cabinet 12, a door 11, and a refrigeration system (not shown in the figure). The cabinet 12 may define at least one front-opening storage compartment 121, and typically multiple compartments, such as a refrigerated storage compartment, a frozen storage compartment, a variable-temperature storage compartment, etc. The specific number and function of the storage compartments can be configured according to pre-defined needs. The refrigerated and frozen storage device 10 of a four-door refrigerator shown in Figure 1 is merely an example; those skilled in the art can configure the specific number, function, and layout of the storage compartments according to their needs. The storage compartment 121 can be divided into spaces using shelves, drawers, etc., to achieve corresponding storage functions, such as chilled, frozen, and dried storage. In some embodiments, one or more preservation storage containers 123 can be arranged within the storage compartment 121. A magnetic field is applied inside the preservation storage container 123 to enhance the preservation effect.

[0067] The food preservation storage container 123 is arranged inside the storage compartment 121 and can be a drawer-type storage container or a storage container with other structures. Magnetic field modules 140 and 150 are installed on the inner or outer side or side wall of the food preservation storage container 123.

[0068] In some embodiments, the magnetic field module includes a first magnetic field module 140 and a second magnetic field module 150, which are arranged relatively apart inside the storage compartment 121, thereby forming a fresh-keeping storage space with a magnetic field between the first magnetic field module 140 and the second magnetic field module 150. The fresh-keeping storage space is used to place the stored items. The first magnetic field module 140 and the second magnetic field module 150 can be arranged vertically or horizontally opposite each other, thereby forming a fresh-keeping storage space between the first magnetic field module 140 and the second magnetic field module 150.

[0069] Each magnetic field module 140 and 150 may include: a housing, magnetic source components 143 and 153, and magnetic conductive plates 142 and 152. The housing defines an installation space, protecting the magnetic source components 143 and 153 and the magnetic conductive plates 142 and 152 from corrosion damage and extending their service life. The magnetic source components 143 and 153 are disposed within the installation space and are used to generate a magnetic field. The magnetic source components 143 and 153 are constructed as permanent magnet sheets capable of uniform magnetization. These permanent magnet sheets can be made of a flexible permanent magnet material, such as a flexible rubber magnetic sheet made by calendering a composite of bonded ferrite magnetic powder and synthetic rubber.

[0070] Magnetic guide plates 142 and 152 are disposed within the installation space and are abutted against magnetic source components 143 and 153 to adjust the magnetic field distribution of magnetic source components 143 and 153. Magnetic guide plates 142 and 152 are made of a material with low coercivity and high permeability, and their area can be slightly larger than that of magnetic source components 143 and 153. The tight fit between magnetic guide plates 142 and 152 and magnetic source components 143 and 153 achieves a zero-gap fit, improving the uniformity of the magnetic field. Testing has shown that magnetic guide plates 142 and 152 can make the magnetic field more uniform and expand its coverage area.

[0071] The encapsulation shell is configured to bring the magnetic source components 143 and 153 closer to the food preservation storage space relative to the magnetic guide plates 142 and 152, while also ensuring accurate magnetic field direction. Specifically, the internal mounting space of the encapsulation shell has different structures to limit the relative positions of the magnetic source components 143 and 153 with respect to the magnetic guide plates 142 and 152, ensuring that the magnetic source components 143 and 153 are closer to the food preservation storage space relative to the magnetic guide plates 142 and 152.

[0072] To address the characteristic that magnetic field strength gradually decreases with distance, the encapsulation shell optimizes the installation space structure to fully utilize the magnetic fields released by magnetic source components 143 and 153. The opposing magnetic poles of the first magnetic field module 140 and the second magnetic field module 150 are opposite poles; for example, the poles facing the magnetic field preservation space can be set as S and N poles respectively; or the poles facing the magnetic field preservation space can be set as N and S poles respectively. This further ensures the uniformity of the magnetic field. That is, the direction of the magnetic field lines is from the first magnetic field module 140 to the second magnetic field module 150; or from the second magnetic field module 150 to the first magnetic field module 140.

[0073] The first magnetic field module 140 and the second magnetic field module 150 can be configured as plates with different structures for easy differentiation. An example is provided where the first magnetic field module 140 is positioned above the second magnetic field module 150, with a vertical spacing between them. Those skilled in the art can implement other configurations based on this, such as the first magnetic field module 140 being positioned horizontally or vertically between the first and second magnetic field modules 150.

[0074] The first magnetic field module 140 includes, from the outside to the inside, the following components according to their relative positions to the preservation and storage space: a first housing 141, a magnetic plate 142, a magnetic source component 143, and a second housing 144. The second housing 144 is interlocked with the first housing 141 (or the second housing 144 is covered by the first housing 141), together defining the space for accommodating the magnetic plate 142 and the magnetic source component 143.

[0075] The second magnetic field module 150 includes, from the outside to the inside, the following components according to their relative positions to the preservation and storage space: a first housing 151, a magnetic source component 153, a magnetic guide plate 152, and a second housing 154. The second housing 154 is interlocked with the first housing 151 (or the second housing 154 is covered by the first housing 151), together defining the space for accommodating the magnetic guide plate 152 and the magnetic source component 153.

[0076] Magnetic field mounting structures 310 are respectively provided on the side walls of the storage compartment 121 on both sides. The two sides of the first magnetic field module 140 and the two sides of the second magnetic field module 150 are respectively mounted on the magnetic field mounting structures 310 to generate a magnetic field that promotes the formation of a fresh-keeping storage environment. In some embodiments, the magnetic field mounting structures 310 are directly provided on the side wall of the inner liner of the box or on the vertical partition of the box, that is, directly formed on the side wall of the storage compartment 121. In other embodiments, when the fresh-keeping storage container 123 is a drawer-type storage container, the magnetic field mounting structures 310 can also be provided on the storage drawer slide rail device on the side wall of the inner liner of the box or on the vertical partition of the box; that is, the magnetic field mounting structures 310 are formed on the storage drawer slide rail device.

[0077] The magnetic field mounting structure 310 may include a slide 312 and a limiting component. The slide 312 can be arranged along the front-rear direction of the housing 12, and the sides of the first magnetic field module 140 and the sides of the second magnetic field module 150 are respectively retractably disposed within the slide 312. That is, the slide 312 has an opening facing the interior of the storage compartment 121, and the two side edges of each magnetic field module 140 and 150 are disposed within the slide 312. The limiting component is disposed on the bottom wall and / or side wall of the slide 312, and limits the position of the magnetic field modules 140 and 150 relative to the slide 312 by abutting against the magnetic field modules 140 and 150. When needed, the user can remove the magnetic field modules 140 and 150 for cleaning.

[0078] The limiting components may include a first limiting member 311, a second limiting member 314, and a limiting rib 313, to limit the magnetic field modules 140 and 150 in multiple directions, ensuring that the magnetic field modules 140 and 150 are installed in the correct position. The first limiting member 311 is disposed on the bottom wall of the slide groove 312 and is used to abut against the sides of the magnetic field modules 140 and 150. The first limiting member 311 may have a guide surface that gradually protrudes towards the magnetic field modules 140 and 150 from front to back, thereby gradually generating elastic deformation during the insertion of the magnetic field modules 140 and 150. That is, the guide surface of the first limiting member 311 is inclined inward from front to back, reducing the resistance during the insertion of the magnetic field modules 140 and 150, and applying limiting pressure from both sides after the magnetic field modules 140 and 150 are installed in place.

[0079] In some embodiments, each groove 312 is provided with a plurality of first limiting members 311. The plurality of first limiting members 311 are spaced apart along the front-back direction of the groove 312 to apply a more uniform limiting pressure. Figure 7 shows an embodiment with two first limiting members 311 at the front and back. Those skilled in the art can provide a greater number of first limiting members 311 based on this.

[0080] The second limiting member 314 is disposed on the upper side wall of the slide groove 312, for abutting against the top of the magnetic field modules 140 and 150. Limiting notches 1411 and 1511 are also provided on the top wall of the magnetic field modules 140 and 150 near the side, corresponding to the second limiting member 312, and configured so that the magnetic field modules 140 and 150 are mounted in the magnetic field mounting structure 310 to accommodate and limit the second limiting member 314. The second limiting member 314 may have a guide surface that gradually slopes downwards from front to back, thereby gradually generating elastic deformation during the insertion of the magnetic field modules 140 and 150, and ultimately engaging with the limiting notches 1411 and 1511.

[0081] The slide 312 is also provided with a limiting rib 313 at the rear end. The limiting rib 313 is used to abut against the rear side of the magnetic field module, thereby limiting the front and rear positions of the magnetic field modules 140 and 150.

[0082] The limiting components on both sides of each magnetic field module 140 and 150 can be symmetrically arranged. The positions of the limiting components on both sides of the first magnetic field module 140 and the second magnetic field module 150 can be set differently to avoid incorrect insertion of the first magnetic field module 140 and the second magnetic field module 150; for example, the number and front-to-back position of the first limiting member 311 configured for the first magnetic field module 140 and the second magnetic field module 150 can be set differently, and the number and length of the limiting ribs 313 can also be set differently. Correspondingly, the positions of the limiting notch 1411 of the first magnetic field module 140 and the limiting notch 1511 of the second magnetic field module 150 are also configured accordingly, so as to cooperate with the first limiting member 311.

[0083] If the first magnetic field module 140 and the second magnetic field module 150 are inserted incorrectly or in reverse, the installation will be hindered or restricted by the limiting components, prompting the installer to adjust the installation method promptly. Specifically, the housing 12 has guide and fixing structures on both sides of the first magnetic field module 140 and the second magnetic field module 150. Furthermore, the positions and / or shapes and / or dimensions of the guide and fixing structures for the first magnetic field module 140 and the second magnetic field module 150 are different. The first magnetic field module 140 and the second magnetic field module 150 have mating structures corresponding to their respective guide and fixing structures to ensure their proper position within the storage compartment 121.

[0084] In the embodiment where the first magnetic field module 140 is arranged above the magnetic field preservation space, the first housing 141 may be the upper half of the encapsulation shell of the first magnetic field module 140, and the second housing 144 may be the lower half of the encapsulation shell of the first magnetic field module 140. The first housing 141 and the second housing 144 are respectively provided with a plurality of mutually cooperating peripheral connecting portions 163 and 164 near their peripheral walls, and the middle portions of the first housing and the second housing are also respectively provided with mutually cooperating central limiting structures 161 and 162.

[0085] In an embodiment where the first magnetic field module 140 is configured as a square plate, the peripheral connecting portions 163 and 164 include snap-fit ​​connection structures and / or screw connection structures. Figures 8 and 9 show that the first housing 141 has snap-fit ​​openings 164 near its edges, while the second housing 144 has claws 163 near its edges that engage with the snap-fit ​​openings 164. In this snap-fit ​​connection embodiment, the peripheral connecting portion includes the snap-fit ​​opening 164 and the cooperating claws 163. Those skilled in the art can design various types of snap-fit ​​connection structures according to specific fixing requirements. The peripheral connecting portions 163 and 164 ensure reliable peripheral connection and fixing of the first magnetic field module 140 and reliably press the magnetic source component 143 and the magnetic guide plate 142 together.

[0086] The first magnetic field module 140 is set up in a low-temperature operating environment of refrigeration and freezing for a long time. Relying solely on the peripheral connecting parts 163 and 164 cannot guarantee that the encapsulation shell can press the magnetic source component 143 and the magnetic guide plate 142 together. This may cause local voids, resulting in increased magnetic resistance in local areas and uneven magnetic field.

[0087] In the field of magnetic fields, those skilled in the art generally believe that ensuring a uniform magnetic field distribution requires ensuring the integrity of the surface of the magnetic source component 143. However, in the magnetic field module 140 of this embodiment, the inventors creatively realized that when the magnetic source component 143 and the magnetic conductive plate 142 are arranged simultaneously, the flatness of their adhesion has a greater impact on the uniformity of the magnetic field. To address this issue, the inventors also attempted to use adhesives to bond the magnetic source component 143 and the magnetic conductive plate 142. However, the thickness of the adhesive is difficult to control, and it will age over long-term use, making it difficult to achieve a flat and even fit between the magnetic source component 143 and the magnetic conductive plate 142.

[0088] Based on the above problems, this embodiment provides a central limiting structure that mutually cooperates with each other in the middle of the first housing 141 and the middle of the second housing 144. The central limiting structure may include a first limiting part 161 and a second limiting part 162. The first limiting part 161 is disposed on the inner surface of the first housing 141 and extends toward the second housing 144. The second limiting part 162 is disposed on the inner surface of the second housing 144 at a position opposite to the first limiting part 161, and the first limiting part 161 and the second limiting part 162 can be connected by a snap-fit ​​structure to limit the distance between the inner surface of the first housing 141 and the inner surface of the second housing 144. That is, the inner middle parts of the first housing 141 and the inner middle parts of the second housing 144 extend relative to each other, cooperate with each other, and are connected at their ends by a snap-fit ​​structure. The magnetic source component 143 and the magnetic guide plate 142 are provided with through holes at positions corresponding to the respective central limiting structures, allowing the central limiting structures to pass through. The central limiting structure can press the central area of ​​the magnetic source component 143 and the magnetic guide plate 142 together, and with the peripheral connecting parts 163 and 164, the magnetic source component 143 and the magnetic guide plate 142 can be tightly fitted together.

[0089] In other embodiments, the central limiting structure may also use other methods, such as including a screw post and a connecting screw. The screw post is disposed on the inner surface of the first housing 141 or the second housing 144. The connecting screw is connected to the screw post from the opposite side to define the distance between the inner surface of the first housing 141 and the inner surface of the second housing 144.

[0090] The enclosure of the second magnetic field module 150 can have a similar structure. In an embodiment where the second magnetic field module 150 is spaced below the first magnetic field module 140, the first housing 151 can be the upper half of the enclosure of the second magnetic field module 150, and the second housing 154 can be the lower half of the enclosure of the second magnetic field module 140.

[0091] The first housing 151 and the second housing 154 are each provided with a plurality of mutually cooperating peripheral connecting parts near their peripheral walls, and each also has a mutually cooperating central limiting structure. The peripheral connecting parts can use snap-fit ​​connection structures and / or screw connection structures. The central limiting structures of the first housing 151 and the second housing 154 also have mutually cooperating central limiting structures, which can use mutually extending and cooperating snap-fit ​​structures. The magnetic source component 153 and the magnetic guide plate 152 are reliably pressed together as a whole to achieve a tight fit.

[0092] The position of the central limiting structure of the first magnetic field module 140 relative to the geometric center of the first magnetic field module 140 is different from the position of the central limiting structure of the second magnetic field module 150 relative to the geometric center of the second magnetic field module 150. For example, the offset method of the central limiting structure of the first magnetic field module 140 in the front-back direction or the left-right lateral direction is different from the offset method of the central limiting structure of the second magnetic field module 150. Accordingly, the magnetic source component 143 and the magnetic guide plate 142 of the first magnetic field module 140 and the magnetic source component 153 and the magnetic guide plate 152 of the second magnetic field module 150 are respectively set differently, which can ensure that the above components will not be mis-assembled.

[0093] The sizes of the first magnetic field module 140 and the second magnetic field module 150 can also be set to be the same or different depending on the space constraints of the housing 12 they are in, and their relative arrangement can be roughly opposite. For example, in some embodiments, the first magnetic field module 140 may be set to be slightly smaller than the second magnetic field module 150 due to the limitation of the cooling air duct or other components.

[0094] Support ribs 181 are provided on the inner surface of the first housing 141 of the first magnetic field module 140, in the area opposite to the magnetic conductive plate 142. Support ribs 181 are also provided on the inner surface of the second housing 144, in the area opposite to the magnetic source component 143. The support ribs 181 abut against the magnetic conductive plate 142 and the magnetic source component 143, so that the magnetic conductive plate 142 and the magnetic source component 143 are tightly fitted together.

[0095] The support ribs 181 can be arranged in a ring shape around the central limiting structures 161 and 162. Multiple support ribs 181 can be provided, and the minimum distance between adjacent support ribs 181 is set to be less than the sum of the thicknesses of the magnetic guide plate 142 and the magnetic source component 143. That is, by limiting the density of the support ribs 181, voids are prevented at the spacing between the support ribs 181. The width of the top surface of the support rib 181 (as the contact surface abutting the magnetic guide plate 142 or the magnetic source component 143) is set to be greater than the sum of the thicknesses of the magnetic guide plate 142 and the magnetic source component 143. The support ribs 181 can also improve the structural strength of the encapsulation shell, and in conjunction with the peripheral connecting parts 163 and 164 and the central limiting structures 161 and 162, achieve long-term structural stability. The minimum distance between the aforementioned support ribs 181 and the width of the top surface of the support ribs 181 are improvements made by the inventors after in-depth research on the structure and material characteristics of the magnetic plate 142 and the magnetic source component 143. After physical verification of the samples, the results exceeded expectations and far surpassed the fit effect when the plane abuts against the magnetic plate 142 or the magnetic source component 143.

[0096] The structure of the support ribs 181 and their relative positions are set according to the situation of the magnetic plate 142 and the magnetic source component 143. On the one hand, this improves the structural strength and stability, and on the other hand, it ensures that the magnetic plate 142 and the magnetic source component 143 are reliably attached.

[0097] The first housing 141 includes a first outer housing panel 1412 and a first outer housing peripheral wall 1413 disposed at the edge of the first outer housing panel 1412. The inner surface of the first outer housing panel 1412 is provided with a first positioning structure 172 for fixing the magnetic conductive plate 142 and a second positioning structure 171 for fixing the magnetic source component 143. The first positioning structure 172 and the second positioning structure 171 together maintain the relative position of the magnetic conductive plate 142 and the magnetic source component 143.

[0098] The first positioning structure 172 includes positioning ribs protruding from the wall surface. The shape formed by the positioning ribs and / or their extensions is adapted to the outer peripheral contour of the magnetic guide plate 142, thereby confining the magnetic guide plate 142 within the area enclosed by the positioning ribs and / or their extensions. That is, after the magnetic guide plate 142 is installed, it snaps into the area defined by the positioning ribs. When the size of the magnetic guide plate 142 is larger than that of the magnetic source member 143, the magnetic guide plate 142 has an extended region on the outer periphery of the area abutting against the magnetic source member 143.

[0099] The second positioning structure 171 includes a protrusion extending from the positioning rib towards the central region of the wall. The outer region of the magnetic plate 142 has a positioning notch at a corresponding position on the protrusion, and the protruding length matches the width of the outer region, thereby causing the end of the protrusion to abut against the magnetic source component 143, thus positioning the magnetic source component 143. The magnetic source component 143 and the magnetic plate 142 are both generally square, and multiple sides of the positioning rib are provided with one or more protrusions. That is, the second positioning structure 171 is arranged at the notch position of the magnetic plate 142, and after the magnetic source component 143 is installed, it is engaged in the area defined by the second positioning structure 171.

[0100] The first positioning structure 172 and the second positioning structure 171 described above can ensure that the magnetic plate 142 and the magnetic source component 143 are installed in the correct manner, and will not be installed backwards or incorrectly.

[0101] The installation process of the first magnetic field module 140 is as follows: the inner side of the first housing 141 is arranged upwards; the magnetic plate 142 is embedded in the first positioning structure 172 on the inner surface of the first outer shell panel 1412 of the first housing 141; then the magnetic source component 143 is arranged on the magnetic plate 142, cooperating with the second positioning structure 171 on the inner surface of the first outer shell panel 1412; the second housing 144 is fastened to the first housing 141, so that the peripheral connecting parts 163 and 164 and the central limiting structures 161 and 162 are reliably connected. Finally, the entire assembly is flipped over to obtain the first magnetic field module 140.

[0102] Since the second housing 154 of the second magnetic field module 150 is similar in structure to the first housing 141 of the first magnetic field module 140, and the support ribs 181 on the plates of the first housing 151 and the second housing 154 that abut against the magnetic source component 153 and the magnetic guide plate 152 are similar in structure to the support ribs 181 of the first magnetic field module 140, no further details will be provided.

[0103] The positioning structure in the first housing 151 of the second magnetic field module 150 is similar to the first positioning structure 172 and the second positioning structure 171 of the first housing 141 of the first magnetic field module 140. The positioning structures respectively limit the magnetic source component 153 and the magnetic guide plate 152. The first housing 151 includes a first outer shell panel 1512 and a first outer shell peripheral wall 1513 disposed on the edge of the first outer shell panel 1512.

[0104] The first outer casing panel 1512 abuts against the side of the magnetic source component 153 opposite to the magnetic guide plate 152. The first outer casing panel 1512 is provided with a first positioning rib 173. The shape formed by the extension lines of the first positioning rib 173 is adapted to the outer peripheral contour of the magnetic source component 153, thereby confining the magnetic source component 153 within the area enclosed by the extension lines of the first positioning rib 173. The height of the first positioning rib 173 is configured such that, when the magnetic source component 153 is mounted on the first outer casing panel, the top of the first positioning rib 173 is flush with or lower than the magnetic source component 153. The magnetic guide plate 152 is larger than the magnetic source component 153, and the above structure can avoid structural interference with the magnetic guide plate 152.

[0105] The first outer casing panel 1512 is further provided with a second positioning rib 174 on the outside of the first positioning rib 173. The height of the second positioning rib 174 is configured such that when the magnetic source member 153 is mounted on the first outer casing panel 1512, the top of the second positioning rib 174 is higher than the magnetic source member 153, and the shape formed by the extension line of the second positioning rib 174 is adapted to the outer peripheral contour of the magnetic guide plate 152, thereby confining the magnetic guide plate 152 within the area enclosed by the extension line of the second positioning rib 174.

[0106] The magnetic source component 153 and the magnetic guide plate 152 are generally square with one corner missing. The shape formed by the extension lines of the first positioning rib 173 and the shape formed by the extension lines of the second positioning rib 174 are also set to have one corner missing, so as to avoid incorrect installation direction.

[0107] The installation process of the second magnetic field module 150 is as follows: The inner side of the first housing 151 is arranged upwards; the magnetic source component 153 is embedded into the first positioning rib 173 on the inner surface of the first outer shell panel 1512 of the first housing 151; then, the magnetic guide plate 152 is arranged on the magnetic source component 153, cooperating with the second positioning rib 174 on the inner surface of the first outer shell panel 1512. The second housing 144 is then fastened onto the first housing 141, ensuring a reliable connection between the peripheral connecting portion and the central limiting structure. Finally, the entire assembly is flipped over to obtain the second magnetic field module 150.

[0108] The second magnetic field module 150 uses two positioning ribs of different heights to position and install two components of different sizes, namely the magnetic source component 153 and the magnetic guide plate 152.

[0109] In one embodiment, the magnetic field module provides another fixed connection structure for the first magnetic field module 140. Multiple screw posts extend from the inner side of the first housing 141, serving as a central limiting structure and a peripheral connecting portion, respectively. Multiple screw holes are provided on the second housing 144, and screws 145 connect and fix the first housing 141 and the second housing 144, as well as limiting their height, through the screw holes and screw posts.
