DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

For example, some operations / steps can be further decomposed, combined or partially merged, so that the actual execution order can be changed according to the actual situation.

When an element is referred to as being “connected” to another element, it can be directly connected to the other element or indirectly connected to the other element through a middle element.

[0035] The terminology used in the present application specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in this application, the terms "first", "second", etc. are only used for describing particular embodiments and do not imply or connote relative importance or a number of indicated technical features. Thus, features defined with "first", "second" etc. can include at least one of the features.

[0036] It should also be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations and includes these combinations.

[0037] With the rapid development of high-tech industries such as batteries, photovoltaics, semiconductors, etc., motor modules are widely used in production lines of various industries to improve production automation, ensure production efficiency and process quality. However, for production lines with high requirements for the accuracy and stability of machining, assembly and other processes, the mechanical spring buffer mechanism used in traditional motor modules may have problems such as fatigue and elastic decay during long-term use. Magnetic springs do not rely on mechanical contact and spring expansion to generate elastic force, so they have better reliability and durability, and can output stable, reliable and easy-to-control buffer force as part of the buffer mechanism while effectively protecting the mechanical structure and components of the motor module.

[0038] With the upgrading of the manufacturing industry such as aerospace, marine power, engineering machinery, etc., the traditional automation equipment also puts forward higher requirements for the range and load capacity of the motor module and the buffer mechanism. However, due to the physical limitations of the material and the limited structural strength of the internal integrated magnetic steel and other permanent magnets of the magnetic spring, increasing the total stroke of the magnetic spring can easily reduce the mechanical structural strength of the permanent magnet itself, thereby reducing the load capacity of the magnetic spring and affecting the reliability and durability of the buffer mechanism and even the entire motor module. The process difficulty and cost of producing and processing the permanent magnet will also be increased. How to effectively improve the range, load capacity and reliability of the magnetic spring through improved manufacturing methods and improved structural design has become a problem to be solved.

[0039] After extending the length of the magnetic steel and permanent magnet inside the magnetic spring, the problem of low adhesive connection assembly strength in the traditional magnetic spring manufacturing process or structural design will be exposed due to the change of internal structure and the improvement of strength requirements, thereby making it a problem to be solved how to improve the structural strength through structural improvement and process improvement to ensure the reliability and stability of the long-stroke magnetic spring in actual application and long-term use under extreme temperature and pressure, long-term use, impact and vibration, etc. Industrial environment.

[0040] In particular, the traditional magnetic spring often directly bonds the terminal assembly to the corresponding port of the hollow shaft tube of the magnetic spring. Once the bonding point is affected by physical weathering, chemical corrosion and other factors, it will cause the connection to loosen and other problems, and then easily cause stability decline, durability deficiency and other situations in long-term use, extreme load and other scenarios, even cause the terminal assembly to be delaminated, loosened and other negative consequences, reduce production efficiency and affect safe production.

Wherein the magnetic spring 100 can include a hollow shaft tube 11, a terminal assembly 12, a magnetic assembly 13 and a working piece 14. Wherein the hollow shaft tube 11 can be provided with a first port 11a and a second port 11b along the axial direction. The terminal assembly 12 can include a first joint 12a and a second joint 12b, the first joint 12a is crimped to the first port 11a, the second joint 12b is crimped to the second port 11b, and the first joint 12a, the second joint 12b and the hollow shaft tube 11 can cooperate to form a mounting cavity 12c.

[0043] Exemplarily, the first joint 12a is installed in the first port 11a by crimping, adhesive connection or combination of the two, or the second joint 12b is installed in the second port 11b by crimping, adhesive connection or combination of the two.

[0044] It can be understood that the crimping connection is a kind of physical connection, which is more reliable, durable, material and process cost saving than traditional adhesive, and can indirectly facilitate the installation of the hollow shaft tube 11, without the need to additionally set external threads, buckles and other connecting components at the end, saving material and process cost.

[0045] It can be further understood that the crimping part 17 on the hollow shaft tube 11 can be used as a mounting part to facilitate the installation of the magnetic spring 100 and the assembly of related mechanisms, devices and equipment applied to the magnetic spring 100, for example, the crimping part 17 can be connected to the load, base and / or limiting piece as a mounting part.

[0046] The working piece 14 can be arranged on the hollow shaft tube 11, wherein the working piece 14 is movable along the axial direction of the hollow shaft tube 11, the working piece 14 is provided with a mounting part, the mounting part can be used to connect the load, the fixing seat and / or the limiting piece, and the working piece 14 can interact with the magnetic piece to generate magnetic force.

[0047] In other embodiments, the magnetic force spring 100 can include a hollow shaft tube 11, an end assembly 12, a magnetic assembly 13, a working piece 14, and a filling body 15. The hollow shaft tube 11 can be provided with a first port 11a and a second port 11b along an axial direction thereof.

[0048] In some embodiments, the first port 11a and / or the second port 11b provided along the axial direction of the hollow shaft tube 11 can be further provided with external threads for connecting a fixing base or a load.

[0049] It can be understood that the hollow shaft tube 11 can be further provided with other ports to facilitate electrical, liquid, or gas communication between the internal components of the hollow shaft tube 11 and external devices.

[0050] The end assembly 12 can include a first joint 12a and a second joint 12b. The first joint 12a can be mounted to the first port 11a, and the second joint 12b can be mounted to the second port 11b. The first joint 12a, the second joint 12b, and the hollow shaft tube 11 can cooperate to form a mounting cavity 11c.

[0051] In some embodiments, the first joint 12a can be provided with a rivet groove 16, and the first joint 12a can be riveted to the hollow shaft tube 11 through the rivet groove 16; and / or, the second joint 12b can be provided with a rivet groove 16, and the second joint 12b can be riveted to the hollow shaft tube 11 through the rivet groove 16.

[0052] For example, the hollow shaft tube 11 can be provided with a riveting portion 17, and the peripheral side of the end assembly 12 can be provided with a rivet groove 16 corresponding to the riveting portion 17 of the hollow shaft tube 11. The rivet groove 16 of the end assembly 12 can be riveted to the riveting portion 17 of the hollow shaft tube 11 through a press ring riveting process.

[0053] It can be understood that riveting the end assembly 12 to the hollow shaft tube 11 through the rivet groove 16 can avoid the problems of limited connection strength, unstable properties, and easy weathering and falling caused by adhering the end assembly 12 to the hollow shaft tube 11 in traditional technical solutions.

[0054] It can be further understood that the end assembly 12 can be mounted to the corresponding port of the hollow shaft tube 11 through a riveting process such as press ring riveting, rivet connection, and hot riveting.

[0055] In some embodiments, the first joint 12a and / or the second joint 12b can be provided with a mounting hole 12c, which can be used to connect a load, a fixing base, or a limiting piece.

[0056] The magnetic assembly 13 can be arranged in the mounting cavity 11c, and the magnetic assembly 13 includes a plurality of magnetic pieces.

[0057] In some embodiments, the magnetic assembly 13 comprises at least a first magnetic piece 13a and a second magnetic piece 13b, and the first magnetic piece 13a and the second magnetic piece 13b are bonded and / or magnetically attracted to each other along the corresponding surfaces perpendicular to the axial direction of the hollow shaft tube 11.

[0058] In some embodiments, the magnetic assembly 13 comprises at least a first magnetic piece 13a, a second magnetic piece 13b, a third magnetic piece 13c, and a fourth magnetic piece 13d, and the magnetic assembly 13 is arranged in the mounting cavity 11c.

[0059] In some embodiments, please refer to Figure 5 As shown in Figures 1 to 5 the first magnetic piece 13a and the fourth magnetic piece 13d are bonded and magnetically repelled to each other along the corresponding surfaces perpendicular to the axial direction of the hollow shaft tube 11, and the second magnetic piece 13b and the third magnetic piece 13c are bonded and magnetically repelled to each other along the corresponding surfaces perpendicular to the axial direction of the hollow shaft tube 11.

[0060] For example, the first magnetic piece 13a and the fourth magnetic piece 13d can be bonded to each other along the corresponding surfaces perpendicular to the axial direction of the hollow shaft tube 11 by using epoxy magnetic steel adhesive, acrylic magnetic steel adhesive, or other magnetic steel adhesives.

[0061] For example, the second magnetic piece 13b and the third magnetic piece 13c can be bonded to each other along the corresponding surfaces perpendicular to the axial direction of the hollow shaft tube 11 by using epoxy magnetic steel adhesive, acrylic magnetic steel adhesive, or other magnetic steel adhesives.

[0062] It can be understood that by connecting the surfaces magnetically repelled to each other, on the one hand, the shape and position of the magnetic assembly 13 can be kept stable, and the overall rigidity of the magnetic assembly 13 can be enhanced, and on the other hand, the magnetic field distribution can be optimized to form a stable force field, so that the magnetic force spring 100 can provide stable and strong counterforce when subjected to external force.

[0063] In some embodiments, the surfaces of the first magnetic piece 13a and the fourth magnetic piece 13d perpendicular to the axial direction of the hollow shaft tube 11 can be magnetically attracted to the corresponding surfaces of the third magnetic piece 13c and the second magnetic piece 13b.

[0064] It can be understood that by magnetically attracting the surfaces of the first magnetic piece 13a and the fourth magnetic piece 13d perpendicular to the axial direction of the hollow shaft tube 11 to the corresponding surfaces of the third magnetic piece 13c and the second magnetic piece 13b, the traditional integrated magnetic steel can be split into multiple small pieces along the surfaces perpendicular to the axial direction of the hollow shaft tube 11, so that the volume of the magnetic steel raw material can be smaller, on the one hand, the cost of raw materials can be reduced, and the resource consumption in the production, processing, transportation, and other links can be reduced, and on the other hand, the problems of structural brittleness and limited strength caused by the physical and chemical properties of the magnetic steel material when the volume of the magnetic steel is too large can be alleviated, and the overall reliability and durability of the magnetic force spring 100 can be improved.

[0065] It can be further understood that, by improving the arrangement and bonding of the magnetic components in the magnetic assembly 13, the magnetic force spring 100 can have good linear force-displacement characteristics, and the use performance of the magnetic force spring 100 can be improved.

[0066] In some embodiments, the second magnetic component 13b is close to the second port 11b, the third magnetic component 13c is away from the second port 11b, the first magnetic component 13a and the third magnetic component 13c have equal lengths along the axial direction of the hollow shaft tube 11, and the second magnetic component 13b and the fourth magnetic component 13d have equal lengths along the axial direction of the hollow shaft tube 11.

[0067] It can be understood that, the first magnetic component 13a and the second magnetic component 13b being close to the second port 11b means that, compared with the third magnetic component 13c and the fourth magnetic component 13d, the first magnetic component 13a and the second magnetic component 13b are closer to the second port 11b.

[0068] Further, the third magnetic component 13c and the fourth magnetic component 13d being away from the second port 11b means that, compared with the first magnetic component 13a and the second magnetic component 13b, the third magnetic component 13c and the fourth magnetic component 13d are farther away from the second port 11b.

[0069] In some embodiments, the sum of the lengths of the first magnetic component 13a and the fourth magnetic component 13d along the axial direction of the hollow shaft tube 11 is equal to the sum of the lengths of the third magnetic component 13c and the second magnetic component 13b along the axial direction of the hollow shaft tube 11.

[0070] In some embodiments, at least one face of the first magnetic component 13a and the second magnetic component 13b perpendicular to the axial direction of the hollow shaft tube 11 is flush, and at least one face of the third magnetic component 13c and the fourth magnetic component 13d perpendicular to the axial direction of the hollow shaft tube 11 is flush.

[0072] In some embodiments, the lengths of the first magnetic component 13a and the third magnetic component 13c along the axial direction of the hollow shaft tube 11 can be greater than the lengths of the second magnetic component 13b and the fourth magnetic component 13d along the axial direction of the hollow shaft tube 11.

[0073] It can be understood that, through the cross-stacked arrangement, the structural rigidity of the magnetic assembly 13 can be further improved, and the reliability, durability and safety of the magnetic force spring 100 product as a whole can be improved, avoiding uneven stress leading to deformation of the magnetic assembly 13, destroying the buffering performance of the magnetic force spring 100, and other problems.

[0074] It can be further understood that, the cross-stacked arrangement and the bonding method of the magnetic members, including but not limited to the arrangement of only four magnetic members, can be further expanded according to the method, by changing the total length and / or outer diameter of the magnetic assembly, to adapt to the user's demand for different stroke lengths and / or the user's demand for different magnetic force sizes.

[0075] In some embodiments, each magnetic member in the magnetic assembly 13 is a cylinder. The circumferential side of the cylinder can be provided with a connecting surface 13f, which can be attracted and / or bonded to the corresponding connecting surface 13f of other magnetic members.

[0076] For example, the end surface of the cylinder of the magnetic member can be semicircular, wherein the cylindrical surface corresponding to the straight edge of the semicircle is the mounting surface, and the cylindrical surface corresponding to the arc edge of the semicircle can be fitted with the inner wall of the hollow shaft tube 11.

[0078] The filler 15 can include a first filler 15a, which can be disposed in the hollow shaft tube 11 and close to the first port 11a.

[0079] The first filler 15a close to the first port 11a can be understood as the position of the first filler 15a being closer to the first port 11a than to the second port 11b. For example, the filler 15 can also include an elastomer and / or a colloid.

[0080] For example, a resin, polyurethane or other filling glue can be used to form the filler 15 in the hollow shaft tube 11; and / or an elastomer such as rubber or TPE can be used for filling, thereby preventing the magnetic assembly 13 from shifting during use of the magnetic force spring 100.

[0081] It can be understood that, by providing the first filler 15a, the filler 15 is provided in the hollow shaft tube 11, thereby preventing the magnetic assembly 13 from vibrating or shifting during use of the magnetic force spring 100.

[0083] It can be understood that by providing the second filler 15b, it is possible to adjust the relative position of the magnetic assembly 13 in the total stroke of the magnetic force spring 100, which is beneficial for users to reasonably design the magnetic field distribution according to simulation or calculation, and further improve the use performance of the magnetic force spring 100.

[0090] S101, a joint in the terminal assembly 12 is installed on the corresponding port of the hollow shaft pipe 11.

[0091] For example, the first joint 12a can be installed on the first port 11a through a press ring riveting process, an adhesive process, or a combination of the two, or the second joint 12b can be installed on the second port 11b through a press ring riveting process, an adhesive process, or a combination of the two.

[0092] It can be understood that the installation of the terminal assembly 12 to the corresponding port of the hollow shaft tube 11 through the ring riveting process, the gluing process or the combination of the two can improve the firmness of the connection point of the terminal assembly 12 and the hollow shaft tube 11, especially the installation of the terminal assembly 12 to the corresponding port of the hollow shaft tube 11 through the ring riveting process or the combination of the ring riveting process and the gluing process. On the one hand, the physical riveting has better corrosion and weather resistance than the chemical gluing, and can still maintain good firmness of the connection under the environment of long-term use, temperature and pressure changes and vibration impact, thereby improving the mechanical strength and reliability, durability, accuracy and other use performances of the magnetic spring 100 as a whole.

[0100] The one end of the second filler 15b can abut or be connected to the terminal assembly 12, and the other end of the second filler 15b can abut or be connected to the magnetic assembly 13.

[0101] It can be understood that the first filler 15a and the second filler 15b can be arranged in the same mounting cavity, and if the hollow shaft tube 11 can form a plurality of mounting cavities after the magnetic assembly 13 is arranged, the second filler 15b can be arranged in a different mounting cavity from the first filler 15a.

[0102] It can be further understood that by arranging the filler 15, the magnetic assembly 13 can be prevented from being displaced, and the structural strength thereof can be improved.

[0103] S104, another joint in the terminal assembly 12 is arranged in the corresponding port of the hollow shaft tube 11.

[0104] For example, the first joint 12a is arranged in the first port 11a by a press ring riveting process, a gluing process, or a combination of the two, or the second joint 12b is arranged in the second port 11b by a press ring riveting process, a gluing process, or a combination of the two.

[0105] For example, the first joint 12a exerts an axial pressure on the magnetic assembly 13 and the filler 15 along the hollow shaft tube 11, and the first joint 12a is arranged in the first port 11a by a press ring riveting process; or,

[0106] The second joint 12b exerts an axial pressure on the magnetic assembly 13 and the filler 15 along the hollow shaft tube 11, and the second joint 12b is arranged in the second port 11b by a press ring riveting process.

[0107] It can be understood that by exerting the pressure, the magnetic assembly 13 and the filler 15 can be more compact, which helps to improve the structural strength of the filler 15, the colloid air-drying consolidation contained in the magnetic assembly 13, and the entire machine assembly of the magnetic force spring 100.

[0108] It can be further understood that the press ring riveting process can utilize the force-displacement law of the magnetic force spring 100 to maintain the pressure exerted during the manufacturing process by riveting, further ensuring the tightness between the inside of the magnetic assembly 13 and the magnetic assembly 13 and the filler 15, thereby improving the mechanical structural strength of the magnetic force spring 100 and enhancing the reliability, durability, and stability of the magnetic force spring 100.

[0109] The embodiment of the present application proposes a buffering mechanism, which can include the magnetic force spring 100 in any embodiment of the present application.

[0110] The embodiment of the present application proposes a motor module, which can include the buffering mechanism in any embodiment of the present application and / or the magnetic force spring 100 in any embodiment of the present application.

[0111] Those skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples without contradiction.

[0112] The above merely describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements shall be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
