Description

Technical Field

[0001] This utility model relates to the field of magnet installation technology, and in particular to a magnet installation structure and mechanical equipment. Background Technology

[0002] Installing magnets on products serves to fix, position, attract, and reinforce them. For example, in automotive components such as electric water pump drives, EGR valves, and fuel shut-off valves, magnets can help improve equipment performance and reliability. The traditional method of fixing magnets to plastic products is through an interference fit, where the magnet is pressed into a hole in the plastic part using a crimping machine. However, magnets fixed in this way are prone to falling off due to significant vibrations and frequent temperature changes causing thermal expansion and contraction of the plastic part. Utility Model Content

[0003] Therefore, it is necessary to provide a magnet mounting structure and mechanical device to address the problem that magnets are prone to falling off due to large vibrations or frequent high and low temperature changes.

[0004] A magnet mounting structure includes: a housing assembly having a receiving space; a magnetic element disposed on the housing assembly and located in the receiving space; and a limiting element disposed on the housing assembly and adjacent to the receiving space, the limiting element and the receiving space being located on the same side of the housing assembly, the limiting element being used to cooperate with the magnetic element.

[0005] The first aspect of this application discloses a magnet mounting structure that provides a precise mounting position for the magnetic component on the housing assembly through the configuration of a receiving space. When the device is subjected to external factors such as vibration, the receiving space ensures that the magnetic component remains in the preset position and will not shift due to vibration. By cooperating with a limiting component, this fixing method further enhances the stability of the magnetic component. Even if frequent high and low temperature changes cause thermal expansion and contraction of the housing assembly, the limiting and blocking effect of the limiting component prevents the magnetic component from falling out of the receiving space. This design forms a dual fixing mechanism of "spatial constraint + mechanical limiting," resulting in excellent fixing performance. Furthermore, it eliminates the need for additional connecting parts such as bolts and riveting tools, reducing assembly difficulty and making assembly simpler, more convenient, and more reliable. Compared with traditional riveting techniques for fixing magnets, the product as a whole will not be damaged during installation, and the magnet can be disassembled and reinstalled if it is not installed correctly the first time, making it more practical.

[0006] In one embodiment, one of the housing assembly and the magnetic component is provided with a limiting structure, and the other of the housing assembly and the magnetic component is provided with an adapter groove, the limiting structure being adapted to the adapter groove. The adaptation of the limiting structure to the adapter groove further improves the assembly stability of the magnetic component and the housing assembly. This design provides positioning for the installation of the magnetic component; the assembly process only requires aligning the limiting structure with the adapter groove and inserting it to complete the installation of the magnetic component, eliminating the need for complex alignment operations and simplifying the assembly process.

[0007] In one embodiment, the magnetic component is provided with the adapter groove, and the housing assembly has the limiting structure formed thereon, which is a rib that mates with the adapter groove. The adapter groove provides precise guidance for the insertion of the rib. During installation, the rib can smoothly enter the predetermined position along the adapter groove, ensuring accurate installation of the magnetic component on the housing assembly. This design enables precise installation while further securing the position of the magnetic component.

[0008] In one embodiment, the receiving space includes a first adapting space and a second adapting space, which are connected. The magnetic component includes a first magnetic part and a second magnetic part. The first magnetic part is disposed on the housing assembly and located in the first adapting space, and the second magnetic part is disposed on the first magnetic part and located in the second adapting space. The limiting member can cooperate with the second magnetic part. The stepped receiving space and the magnetic component achieve a tight fit and a stable connection. This tight-fitting structural design makes the connection between the magnetic component and the housing assembly more secure, effectively preventing the magnetic component from loosening or falling off during use. Furthermore, the strict matching of the shapes of the receiving space and the magnetic component, along with the communication between the first and second adapting spaces, ensures that the magnetic component can only be placed in a specific direction and position during installation, effectively avoiding misalignment caused by installation angle deviations or inaccurate positioning.

[0009] In one embodiment, the first magnetic part is adapted to the first adapting space. This tight fit between the first magnetic part and the first adapting space—that is, the first magnetic part abutting against the cavity wall of the first adapting space—makes the connection between the magnetic component and the housing assembly more secure, effectively preventing the magnetic component from loosening or falling off during use.

[0010] In one embodiment, the second magnetic part is adapted to the second adapting space. By adapting the second magnetic part to the second receiving cavity, i.e., by abutting against the cavity wall of the second adapting space, this tightly fitted structural design makes the connection between the magnetic component and the housing assembly more secure, effectively preventing the magnetic component from loosening or falling off during use.

[0011] In one embodiment, the magnetic component is provided with an adapter groove that mates with the housing assembly, the adapter groove surrounding the first magnetic part. By surrounding the first magnetic part with the adapter groove, the ribs of the housing assembly can comprehensively restrict the degrees of freedom of the magnetic component, resulting in better stability and effectively preventing loosening or detachment during use. Furthermore, the magnetic component experiences more uniform force, leading to a better restraint effect.

[0012] In one embodiment, there are multiple limiting members, all disposed on the housing assembly and located on the same side of the housing assembly. Each limiting member is used to cooperate with the magnetic component. By distributing multiple limiting members along the edge of the magnetic component, an enclosing limiting assembly is formed. Each limiting member applies an independent constraint force to different areas of the magnetic component, such as the corners, center, or easily displaced parts, collectively constructing a multi-point fixing system. This design allows the magnetic component to maintain overall stability under complex stress scenarios such as oblique impacts and high-frequency vibrations, avoiding the risk of loosening due to the failure of a single limiting point.

[0013] In one embodiment, the limiting member is detachably mounted on the housing assembly. This detachable mounting of the limiting member simplifies and facilitates the installation of the magnetic component. Furthermore, it allows for rapid adaptation to different magnetic components, improving the product's versatility and flexibility. This design also simplifies the assembly process and increases assembly efficiency.

[0014] In one embodiment, the limiting member includes a support portion and a latching portion. The support portion is disposed on the housing assembly and adjacent to the receiving space. The latching portion is disposed on the support portion and located at the end of the support portion, and the latching portion can abut against the magnetic component. The support portion provides a stable support base for the latching portion. Through the coordinated action of the support portion and the latching portion, the magnetic component can be limited and fixed from multiple directions. For example, the support portion supports and restricts the movement of the magnetic component in the horizontal direction, while the latching portion applies a certain pressure to the magnetic component in the vertical direction, making the magnetic component fit tightly against the receiving space.

[0015] In one embodiment, a first side facing the magnetic component is formed on the support portion, and a second side facing the magnetic component is formed on the latching portion. The first side and the second side intersect to form an angle α. The magnetic component can abut against the limiting component. When the magnetic component abuts against the limiting component, the magnetic component is located at or near the angle α. By positioning the magnetic component at or near the angle α when it abuts against the limiting component, the magnetic component can be more effectively limited and fixed from multiple directions, resulting in a better limiting effect of the limiting component on the magnetic component.

[0016] In one embodiment, the included angle α is 120 degrees. With an included angle α of 120 degrees, the disassembly and positioning of the limiting component are more effective. The 120-degree included angle α formed by the intersection of the first and second sides allows for more effective positioning and fixing of the magnetic component from multiple directions.

[0017] In one embodiment, the first side can abut against the magnetic element. This abutment of the first side improves the secure mounting of the magnetic element. This stable support helps improve the stability of the fit between the magnetic element and the receiving space, ensuring the magnet can function continuously and stably.

[0018] In one embodiment, the second side can abut against the magnetic element. This abutment of the second side improves the secure mounting of the magnetic element. This stable support helps improve the stability of the fit between the magnetic element and the receiving space, ensuring the magnet can function continuously and stably.

[0019] A mechanical device comprising: the aforementioned magnet mounting structure.

[0020] The second aspect of this application discloses a mechanical device in which the aforementioned magnet mounting structure allows magnetic components, such as magnets, to be installed without the need for fixtures or equipment, enabling quick manual installation with low assembly difficulty. This installation method prevents magnets from falling off due to vibration or thermal expansion and contraction, and allows for repeated installation even if the magnetic component is not installed correctly the first time, without damaging the product. This makes installation more convenient and saves on process and labor costs. Attached Figure Description

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] Example 1

[0036] like Figure 1-2 and Figure 4-5 As shown, this embodiment discloses a magnet mounting structure, including: a housing assembly 1, the housing assembly 1 having a receiving space 101; a magnetic element 2, the magnetic element 2 being disposed on the housing assembly 1 and located at the receiving space 101; and a limiting element 3, the limiting element 3 being disposed on the housing assembly 1 and adjacent to the receiving space 101, the limiting element 3 and the receiving space 101 being located on the same side of the housing assembly 1, the limiting element 3 being used to cooperate with the magnetic element 2.

[0037] The first aspect of this application discloses a magnet mounting structure, in which the accommodating space 101 provides a precise mounting position for the magnetic component 2 on the housing assembly 1. When the device is affected by external factors such as vibration, the accommodating space 101 ensures that the magnetic component 2 always remains in the preset position and will not shift due to vibration. The fixing method further enhances the stability of the magnetic component 2 by cooperating with the limiting component 3. Even if frequent high and low temperature changes cause thermal expansion and contraction of the housing assembly 1, the limiting and blocking effect of the limiting component 3 prevents the magnetic component 2 from falling out of the accommodating space 101. This design forms a dual fixing mechanism of "spatial constraint + mechanical limiting," resulting in good fixing effect. Furthermore, it eliminates the need for additional connecting parts such as bolts and riveting tools, reducing assembly difficulty and making assembly simpler, more convenient, and more reliable. Compared with traditional riveting techniques for fixing magnets, the product as a whole will not be damaged during installation, and the magnet can be disassembled and reinstalled if it is not installed correctly the first time, making it more practical.

[0038] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one of the housing assembly 1 and the magnetic component 2 is provided with a limiting structure 11, and the other of the housing assembly 1 and the magnetic component 2 is provided with an adapter groove 201, wherein the limiting structure 11 is adapted to the adapter groove 201. By adapting the limiting structure 11 to the adapter groove 201, the assembly stability of the magnetic component 2 and the housing assembly 1 is further improved. This design provides positioning for the installation of the magnetic component 2; the assembly process only requires aligning the limiting structure 11 with the adapter groove 201 and inserting it to complete the installation of the magnetic component 2, eliminating the need for complex alignment operations and reducing assembly difficulty.

[0039] like Figure 2 , Figure 3 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the magnetic component 2 is provided with the adapter groove 201, and the housing assembly 1 is formed with the limiting structure 11, the limiting structure 11 being a rib, the rib being adapted to the adapter groove 201. The configuration of the adapter groove 201 provides precise guidance for the insertion of the rib. During installation, the rib can smoothly enter the predetermined position along the adapter groove 201, ensuring that the installation position of the magnetic component 2 on the housing assembly 1 is accurate. This design enables precise installation while further fixing the position of the magnetic component 2.

[0040] like Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the accommodating space 101 includes a first adapting space 1011 and a second adapting space 1012, the first adapting space 1011 and the second adapting space 1012 are connected, the magnetic component 2 includes a first magnetic part 21 and a second magnetic part 22, the first magnetic part 21 is disposed on the housing assembly 1 and located at the first adapting space 1011, the second magnetic part 22 is disposed on the first magnetic part 21 and located at the second adapting space 1012, and the limiting member 3 can cooperate with the second magnetic part 22. The stepped accommodating space 101 and the magnetic component 2 can achieve a tight fit to form a stable connection. This tight-fitting structural design makes the connection between the magnetic component 2 and the housing assembly 1 more secure, effectively preventing the magnetic component 2 from loosening or falling off during use. Furthermore, the shapes of the accommodating space 101 and the magnetic component 2 are strictly matched, and the first adapting space 1011 and the second adapting space 1012 are connected, so that the magnetic component 2 can only be placed in a specific direction and position during the installation process, effectively avoiding misalignment installation problems caused by installation angle deviation or inaccurate position.

[0041] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first magnetic part 21 is adapted to the first adaptation space 1011. By adapting the first magnetic part 21 to the first adaptation space 1011, that is, by abutting the cavity wall of the first adaptation space 1011, this tightly fitted structural design makes the connection between the magnetic component 2 and the housing assembly 1 more secure, effectively preventing the magnetic component 2 from loosening or falling off during use.

[0042] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second magnetic part 22 is adapted to the second adaptation space 1012. By adapting the second magnetic part 22 to the second receiving cavity, that is, by abutting the cavity wall of the second adaptation space 1012, this tightly fitted structural design makes the connection between the magnetic component 2 and the housing assembly 1 more secure, effectively preventing the magnetic component 2 from loosening or falling off during use.

[0043] like Figure 2 , Figure 3 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the magnetic component 2 is provided with an adapter groove 201 that mates with the housing assembly 1, and the adapter groove 201 is arranged around the first magnetic part 21. By arranging the adapter groove 201 around the first magnetic part 21, the protruding ribs of the housing assembly 1 can comprehensively restrict the degrees of freedom of the magnetic component 2, resulting in better stability of the magnetic component 2 and effectively preventing loosening or detachment during use. Furthermore, the magnetic component 2 experiences more uniform force, resulting in a better restraining effect.

[0044] like Figure 1 , Figure 4 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of limiting members 3 is multiple, all of which are disposed on the housing assembly 1 and located on the same side of the housing assembly 1, and all of which are used to cooperate with the magnetic member 2. By distributing multiple limiting members 3 along the edge of the magnetic member, an enclosing limiting assembly is formed. Each limiting member 3 applies an independent constraint force to different areas of the magnetic member 2, such as the four corners, the center, or easily displaced parts, jointly constructing a multi-support fixing system. This design enables the magnetic member 2 to maintain overall stability in complex stress scenarios such as oblique impacts and high-frequency vibrations, avoiding the risk of loosening due to the failure of a single limiting point.

[0045] In addition to the features of the above embodiments, this embodiment further specifies that the limiting member 3 is detachably disposed on the housing assembly 1. By detachably disposing the limiting member 3 on the housing assembly 1, the installation of the magnetic member 2 becomes simpler and more convenient. Furthermore, it allows for rapid adaptation to different magnetic members 2, improving the product's versatility and flexibility. This design simplifies the assembly process and increases assembly efficiency.

[0046] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting member 3 includes a support portion 31 and a latching portion 32. The support portion 31 is disposed on the housing assembly 1 and is adjacent to the receiving space 101. The latching portion 32 is disposed on the support portion 31 and is located at the end of the support portion 31. The latching portion 32 can abut against the magnetic member 2. The configuration of the support portion 31 provides a stable support foundation for the latching portion 32. Through the coordinated action of the support portion 31 and the latching portion 32, the magnetic member 2 can be limited and fixed from multiple directions. For example, the support portion 31 supports and restricts the movement of the magnetic member 2 in the horizontal direction, while the latching portion 32 applies a certain pressure to the magnetic member 2 in the vertical direction, so that the magnetic member 2 is tightly fitted with the receiving space 101.

[0047] like Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first side surface 301 facing the magnetic component 2 is formed on the support portion 31, and a second side surface 302 facing the magnetic component 2 is formed on the latching portion 32. The first side surface 301 and the second side surface 302 intersect to form an angle α. The magnetic component 2 can abut against the limiting member 3. When the magnetic component 2 abuts against the limiting member 3, the magnetic component 2 is located at the angle α or close to the angle α. By having the magnetic component 2 located at the angle α or close to the angle α when it abuts against the limiting member 3, the magnetic component 2 can be more effectively limited and fixed from multiple directions, thereby improving the limiting effect of the limiting member 3 on the magnetic component 2.

[0048] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the included angle α is 120 degrees. With the included angle α being 120 degrees, the disassembly and positioning effect of the limiting member 3 is better. By forming a 120-degree included angle α through the intersection of the first side surface 301 and the second side surface 302, the magnetic member 2 can be more effectively fixed and positioned from multiple directions.

[0049] In addition to the features of the above embodiments, this embodiment further specifies that the first side surface 301 can abut against the magnetic component 2. Because the first side surface 301 can abut against the magnetic component 2, the installation of the magnetic component 2 is more secure. This stable support helps improve the stability of the fit between the magnetic component 2 and the receiving space 101, ensuring that the magnet can continuously and stably perform its function.

[0050] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second side 302 can abut against the magnetic element 2. Because the second side 302 can abut against the magnetic element 2, the installation of the magnetic element 2 is more secure. This stable support helps improve the stability of the fit between the magnetic element 2 and the receiving space 101, ensuring that the magnet can continuously and stably perform its function.

[0053] The second aspect of this application discloses a mechanical device in which the magnetic component 2, such as a magnet, can be installed quickly and manually without the need for fixtures, thanks to the aforementioned magnet mounting structure. This installation method makes the magnet less likely to fall off due to vibration or thermal expansion and contraction, and allows for repeated installation even if the magnetic component 2 is not installed correctly the first time, without damaging the product. This makes installation more convenient and saves on process and labor costs.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
