DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the production personnel in the art, the utility model will be further described below in combination with the embodiments and drawings, and the content mentioned in the implementation manner is not a limitation of the utility model.

[0025] Please refer to Figures 1 to 6 The low-cost staggered magnet assembly of the utility model, as shown in the figure, comprises a first magnetic component 1, the first magnetic component 1 comprises a first magnetic block 101 and a second magnetic block 102, the first magnetic block 101 and / or the second magnetic block 102 are permanent magnets, the number of the first magnetic block 101 and the second magnetic block 102 is multiple, and the first magnetic block 101 and the second magnetic block 102 are staggered.

[0026] In the embodiment, the first magnetic block 101 and the second magnetic block 102 are staggered to present that there is a second magnetic block 102 between any two adjacent first magnetic blocks 101, and there is a first magnetic block 101 between any two adjacent second magnetic blocks 102.

[0027] In actual use, the production personnel assembles the first magnetic assembly 1 by assembling the first magnetic blocks 101 and the second magnetic blocks 102 in an interlaced manner. Specifically, there is one second magnetic block 102 between any two adjacent first magnetic blocks 101, and there is one first magnetic block 101 between any two adjacent second magnetic blocks 102. Since the length, width or thickness of the first magnetic blocks 101 and the second magnetic blocks 102 are obviously different, the production personnel can quickly distinguish the first magnetic blocks 101 and the second magnetic blocks 102 and assemble them in the interlaced arrangement. In the conventional magnet assembly, the length, width and thickness of the first magnetic blocks 101 and the second magnetic blocks 102 are similar, so that the production personnel cannot distinguish the first magnetic blocks 101 and the second magnetic blocks 102 in the production and assembly process, which may cause mixing and low assembly efficiency. By interlacing the first magnetic blocks 101 and the second magnetic blocks 102, the production personnel can quickly distinguish the first magnetic blocks 101 and the second magnetic blocks 102 and assemble them in the interlaced arrangement, which can effectively improve the production efficiency and reduce the labor cost. The interlaced arrangement of the first magnetic blocks 101 and the second magnetic blocks 102 can form a more stable magnetic field of the first magnetic assembly 1, which can appropriately reduce the requirement for the magnet material and effectively reduce the production cost.

[0028] Specifically, the low-cost misaligned magnet assembly further includes a second magnetic assembly 2 for being attached to the first magnetic assembly 1. The two ends of the second magnetic assembly 2 are aligned with the two ends of the first magnetic assembly 1, and the central axis of the second magnetic assembly 2 coincides with the central axis of the first magnetic assembly 1. The width and thickness of the second magnetic assembly 2 are smaller than the width and thickness of the first magnetic assembly 1. The second magnetic assembly 2 includes a plurality of third magnetic blocks 104 and fourth magnetic blocks 105, which are interlaced with each other. The third magnetic blocks 104 and / or the fourth magnetic blocks 105 are permanent magnets.

[0029] In this embodiment, the two ends of the second magnetic assembly 2 are aligned with the two ends of the first magnetic assembly 1, and the central axis of the second magnetic assembly 2 coincides with the central axis of the first magnetic assembly 1, which can form a more uniform and stable magnetic field between the first magnetic assembly 1 and the second magnetic assembly 2, and is conducive to the magnetic attachment of the second magnetic assembly 2 close to the first magnetic assembly 1. The third magnetic blocks 104 and the fourth magnetic blocks 105 are interlaced with each other, and any two adjacent third magnetic blocks 104 have one fourth magnetic block 105 therebetween, and any two adjacent fourth magnetic blocks 105 have one third magnetic block 104 therebetween. The length, width or thickness of the third magnetic blocks 104 and the fourth magnetic blocks 105 are obviously different.

[0030] In actual use, the production staff assembles the second magnetic component 2 by staggering the third magnetic block 104 and the fourth magnetic block 105 at intervals. There is a fourth magnetic block 105 between any two adjacent third magnetic blocks 104, and there is a third magnetic block 104 between any two adjacent fourth magnetic blocks 105. Since the length, width or thickness of the third magnetic block 104 and the fourth magnetic block 105 are significantly different, the production staff can quickly identify and distinguish the third magnetic block 104 and the fourth magnetic block 105 and install the staggered arrangement of the magnetic blocks to assemble them. It can effectively improve production efficiency and reduce labor costs. The staggered arrangement of the first magnetic block 101 and the second magnetic block 102 enables the first magnetic component 1 to form a more stable magnetic field, which can appropriately reduce the requirements for the magnet material and effectively reduce production costs.

[0031] Specifically, the first magnetic block 101 is a permanent magnet, and the second magnetic block 102 is a magnetic conductive block 201 .

[0032] In this embodiment, the magnetic block 201 is made of a magnetic material, which can be an iron block. The third magnetic block 104 and the fourth magnetic block 105 are both permanent magnets. The second magnetic block 102 can be arranged opposite the third magnetic block 104 or the fourth magnetic block 105, and the third magnetic block 104 or the fourth magnetic block 105 can be used to attract the second magnetic block 102. The magnetic fields of the first magnetic component 1 and the second magnetic component 2 interact with each other, causing the first magnetic component 1 and the second magnetic component 2 to attract each other. By setting the second magnetic block 102 as the magnetic block 201, the number of permanent magnets used can be reduced, effectively reducing production costs.

[0033] Specifically, the length of the first magnetic block 101 is greater than the length of the second magnetic block 102. In actual use, production personnel can quickly identify and distinguish the first and second magnetic blocks 101 and 102 based on the length difference. This helps production personnel quickly assemble the first magnetic block 101 according to the staggered arrangement of the magnetic blocks, effectively improving production efficiency and reducing labor costs.

[0034] Specifically, the third magnetic block 104 is a permanent magnet, the fourth magnetic block 105 is a magnetic conductive block 201 , the first magnetic block 101 is used to attract the fourth magnetic block 105 , and the third magnetic block 104 is used to attract the second magnetic block 102 .

[0035] In this embodiment, the first magnetic block 101 and the fourth magnetic block 105 have the same length, the second magnetic block 102 and the third magnetic block 104 have the same length, the first magnetic block 101 corresponds to the fourth magnetic block 105, and the second magnetic block 102 corresponds to the third magnetic block 104, so that the magnetic fields of the first magnetic block 101 and the third magnetic block 104 fully act on the second magnetic block 102 and the fourth magnetic block 105, which is beneficial for the first magnetic block 101 to attract the fourth magnetic block 105, and the third magnetic block 104 to attract the second magnetic block 102.

[0036] In actual use, if the first magnetic block 101 is arranged relative to the fourth magnetic block 105, and the second magnetic block 102 is arranged relative to the third magnetic block 104, the magnetic fields of the first magnetic component 1 and the second magnetic component 2 interact with each other, causing the first magnetic component 1 and the second magnetic component 2 to attract each other. If the first magnetic block 101 and the fourth magnetic block 105 are not arranged relative to each other, that is, the second magnetic block 102 and the fourth magnetic block 105 are arranged relative to each other, no magnetic field interaction is generated between the second magnetic block 102 and the fourth magnetic block 105, which will cause the attraction between the first magnetic component 1 and the second magnetic component 2 to decrease. Therefore, during production and assembly, production personnel need to install according to the positional relationship of the first magnetic block 101 corresponding to the fourth magnetic block 105 and the second magnetic block 102 corresponding to the third magnetic block 104. By setting the second magnetic block 102 and the fourth magnetic block 105 as the magnetic conductive block 201, the number of permanent magnets used can be reduced, and production costs can be more effectively reduced.

[0037] Specifically, the first magnetic component 1 and the second magnetic component 2 are both provided with a magnetic conductive sheet 103 , which extends along the length direction or width direction of the magnetic component and is located on both sides of the first magnetic component 1 and the second magnetic component 2 away from each other.

[0038] In this embodiment, the magnetic conductive sheet 103 is a 0.1 mm thick iron sheet. In actual use, production personnel can glue or hot-press the magnetic conductive sheet 103 onto the two sides of the first and second magnetic components 1 and 2 that are separated from each other. The magnetic conductive sheet 103 serves to shield the magnetic field on the side where the magnetic components are mounted, thereby strengthening the magnetic field on the side where the first and second magnetic components 1 and 2 are close to each other, thereby enhancing the attractive force between the first and second magnetic components 1 and 2.

[0039] Specifically, the magnetic poles of the multiple magnetic blocks in the first magnetic assembly 1 and the multiple magnetic blocks in the second magnetic assembly 2 are arranged in a Halbach array.

[0040] In this embodiment, when the first magnetic block 101, the second magnetic block 102, the third magnetic block 104 and the fourth magnetic block 105 are permanent magnets. Figure 4 and Figure 6 , the magnetic pole directions of the first magnetic block 101 and the second magnetic block 102 intersect with each other, the magnetic pole directions of the third magnetic block 104 and the fourth magnetic block 105 intersect with each other, the magnetic pole directions of any two adjacent first magnetic blocks 101 or / and third magnetic blocks 104 are opposite, and the magnetic pole directions of any two adjacent second magnetic blocks 102 or / and fourth magnetic blocks 105 are opposite. When the first magnetic block 101 and the third magnetic block 104 are permanent magnets, and the second magnetic block 102 and the fourth magnetic block 105 are magnetic conductive blocks 201. Figure 3 and Figure 5, the magnetic pole directions of any two adjacent first magnetic blocks 101 or / and third magnetic blocks 104 are opposite. The magnetic pole arrangement of the first magnetic assembly 1 and the second magnetic assembly 2 is in a Halbach array, which can strengthen the magnetic field on the two sides of the first magnetic assembly 1 and the second magnetic assembly 2 close to each other, and effectively improve the utilization rate of the magnetic field.

[0041] Specifically, the first magnetic block 101 is a neodymium iron boron magnet, and the second magnetic block 102 is a ferrite magnet. In this embodiment, the neodymium iron boron magnet has extremely high magnetic performance and can generate a strong magnetic field. Although the magnetic performance of the ferrite magnet is relatively weak compared to the neodymium iron boron magnet, it has the advantages of high stability, low cost, and corrosion resistance. In actual use, the first magnetic block 101 is mainly responsible for providing strong magnetic attraction to realize the function of the first magnetic assembly 1 attracting and closely approaching the second magnetic assembly 2. The second magnetic block 102 in combination with the first magnetic block 101 can play a role in stabilizing the magnetic field and compensate for the possible magnetic field fluctuations of the neodymium iron boron magnet. When the first magnetic assembly 1 and the second magnetic assembly 2 are magnetically attracted, the second magnetic block 102 can also serve as a communication bridge for the third magnetic block 104 or the fourth magnetic block 105 to attract the second magnetic block 102. By setting the first magnetic block 101 as a neodymium iron boron magnet and the second magnetic block 102 as a ferrite magnet, the stability of the magnetic field of the first magnetic assembly 1 can be effectively improved, and the cost can be reduced.

[0042] N55H neodymium iron boron material has good coercive force, and is generally suitable for application environments with certain requirements for temperature stability, with a maximum working temperature of generally 100°C. N55M neodymium iron boron material has better coercive force and higher temperature stability, with a maximum working temperature of generally 120°C. Production personnel can choose appropriate neodymium iron boron material models to make magnets according to the requirements of the working environment.

[0043] The first magnetic block 101 and the second magnetic block 102 are arranged in a rectangular array or a ring array. In actual use, the magnetic assembly presents different arrangement modes according to different application environments. When the magnetic assembly is applied in a rectangular profile environment, the first magnetic block 101 and the second magnetic block 102 are arranged in a rectangular array. When the magnetic assembly is applied in a circular profile or a ring profile, the first magnetic block 101 and the second magnetic block 102 are arranged in a ring array. For example, a permanent magnet stator in a motor.

[0044] Specifically, the first magnetic assembly 1 and the second magnetic assembly 2 have a gap of 1.5 mm. In actual use, the first magnetic assembly 1 and the second magnetic assembly 2 maintain a gap of 1.5 mm, which can maintain good magnetic attraction between the first magnetic assembly 1 and the second magnetic assembly 2. If the first magnetic assembly 1 and the second magnetic assembly 2 are attached to each other, it is not conducive to the user to disassemble.

[0045] Specifically, the low-cost staggered magnet assembly also includes a magnetic frame 203, which is made of a magnetic conductive material. The magnetic frame 203 is provided with a receiving groove 204 for accommodating the magnetic assembly. The magnetic frame 203 is used to concentrate the magnetic fields of the first magnetic assembly 1 and the second magnetic assembly 2 on the exposed side. In this embodiment, the magnetic frame 203 can serve as a magnetic field shield to block the magnetic field of the magnetic assembly covered by the magnetic frame 203 from diverging and concentrate it on the uncovered plane. During actual use, the magnetic frame 203 accommodates the first magnetic assembly 1 and the second magnetic assembly 2, and the magnetic frame 203 exposes the two sides where the first magnetic assembly 1 and the second magnetic assembly 2 are close to each other. The magnetic frame 203 is conducive to enhancing the magnetic field on both sides where the first magnetic assembly 1 and the second magnetic assembly 2 are close to each other, thereby improving the utilization rate of the magnetic field. In addition, the requirements for the magnet material can be appropriately reduced, thereby reducing production costs.

[0046] The above content is only a preferred embodiment of the present invention. For ordinary production personnel in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation of the present invention.
