Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing, and more specifically, to a snap-fit ​​structure and a vehicle. Background Technology

[0002] In the automotive manufacturing field, especially in the design of vehicle body side panels, the fixing and sealing of water pipes have always been key aspects affecting assembly efficiency and cost. Traditional solutions typically involve separate plugs and clips. The plugs are used to seal pre-drilled holes on the vehicle body to prevent external moisture intrusion, while the clips are used to secure the water pipes, ensuring their stability and safety during vehicle operation.

[0003] However, this separate design has obvious drawbacks: in order to install the clips, additional holes must be drilled in the sheet metal parts of the vehicle body side panel, and the installation process of the separate plugs and clips is complicated and requires multiple operations, which makes the assembly line less efficient.

[0004] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0005] This application provides a snap-fit ​​structure and vehicle, which aims to improve the low assembly efficiency of fixing water pipes and sealing holes in the prior art.

[0006] According to one aspect of the embodiments of this application, a snap-fit ​​structure is provided, including: a snap-fit ​​member, one end of which is provided with a locking structure for locking a water pipe, and the other end of which is provided with a sealing structure for sealing a leak hole in the vehicle body.

[0007] The embodiments of this application achieve the following technical effects: by integrating the locking structure and the sealing structure onto the buckle, the problem of requiring separate installation of independent components in the prior art is avoided, the number of parts is reduced, the complexity of assembly and potential errors are reduced, the assembly efficiency is improved, and the problem of low assembly efficiency of fixing water pipes and sealing holes in the prior art is solved.

[0008] Furthermore, the sealing structure includes: an installation section connected to a locking structure, with a limiting space formed between a portion of the installation section and a portion of the locking structure, the installation section being detachably connected to a body leakage hole; and a seal connected to the installation section, the seal being arranged circumferentially along the installation section and disposed within the limiting space; wherein, when the installation section is connected to the body leakage hole, the seal blocks the body leakage hole.

[0009] The above-mentioned optional embodiments of this application achieve the following technical effects: the mounting section is connected to the locking structure, ensuring that while the water pipe is fixed by the clip, it can also form a detachable connection with the body drain hole. A limiting space is formed between the mounting section and the locking structure, and the seal is positioned within the limiting space. When the mounting section is connected to the body drain hole, the seal is compressed and tightly fits against the hole wall, forming an effective waterproof seal to prevent moisture, dust, and other external substances from entering the vehicle body, thereby protecting the vehicle's electronic system and internal components from damage.

[0010] Furthermore, the seal is detachably connected to the mounting section, or the seal is integrally formed with the mounting section.

[0011] The optional embodiments described above achieve the following technical effects: When the seal needs to be replaced due to wear, aging, or damage, the detachable connection allows for individual seal replacement without replacing the entire snap-fit ​​assembly, reducing maintenance costs and time and improving the maintenance efficiency of the device. Simultaneously, replacing the seal without affecting the structural integrity of the mounting section helps extend the service life of the entire snap-fit ​​assembly. Furthermore, the integrated design allows the seal to be positioned synchronously with the mounting section during installation, avoiding problems such as misalignment, twisting, or uneven compression that may occur with independent seals, thus ensuring optimal sealing performance. This design prevents leakage of media such as water and air from the pores, ensuring the safety and comfort of the vehicle.

[0012] Furthermore, the installation section includes: an installation section body, which is connected to the locking structure; and a limiting protrusion, one end of which is connected to the installation section body, and the other end of which extends away from the installation section body, forming a limiting space between the limiting protrusion and part of the locking structure.

[0013] The above-described optional embodiments of this application achieve the following technical effects: one end of the limiting protrusion is connected to the mounting section body, while the other end extends outward, forming a limiting space together with part of the locking structure. The function of the limiting protrusion is to provide precise guidance and restriction for the correct position and compression of the seal when the fastener is installed at the body leakage hole. This structure can prevent the seal from shifting or being over-compressed during assembly, ensuring that its sealing effect within the limiting space reaches the optimal state.

[0014] Furthermore, the limiting protrusion is made of an elastic material.

[0015] The optional embodiments described above achieve the following technical effects: The elastic limiting protrusion can adaptively adjust to slight differences in orifice diameter. Even if there are manufacturing tolerances in the body leakage holes, the limiting protrusion can ensure tight contact between the sealing structure and the hole wall through its own elastic deformation, thereby achieving a more reliable and uniform sealing effect. The limiting protrusion made of elastic material effectively reduces friction during installation, making it easier for the fastener to embed into the body leakage holes and reducing the risk of component damage due to improper assembly. The elastic material has good shock absorption and impact resistance properties, helping the fastener resist stress caused by uneven road surfaces and vehicle vibrations during vehicle operation, maintaining the stability and integrity of the sealing structure, and extending the service life of the overall device.

[0016] Furthermore, there are multiple limiting protrusions, which are spaced apart circumferentially along the mounting section body. The cross-sectional area of ​​the limiting protrusions in the axial direction of the mounting section body gradually decreases in the direction away from the mounting section body.

[0017] The optional embodiments described above achieve the following technical effects: The design of multiple limiting protrusions increases the structural strength of the mounting section body, especially under conditions of significant external pressure or vibration. These limiting protrusions, acting as reinforcement points, effectively disperse external forces, reducing the risk of body breakage or deformation, thereby extending the service life of the snap-fit ​​device. The cross-sectional area of ​​the limiting protrusions gradually decreases, forming a cone-like structure. When the snap-fit ​​is installed into the body's leakage hole, the gradually decreasing cross-sectional area guides the seal to form a progressive contact with the hole wall, ensuring that the seal is uniformly compressed after the snap-fit ​​is fully embedded, forming a tight sealing ring. This design effectively prevents water, gas, or other liquids from leaking from the pores, ensuring excellent sealing performance.

[0018] Furthermore, the locking structure includes: a first locking section; a second locking section, wherein a first end of the second locking section is connected to a first end of the first locking section, the first locking section is rotatably disposed relative to the second locking section, a second end of the first locking section has a locking engagement with a second end of the second locking section to lock the position of the water pipe, and a second end of the first locking section has a disengagement from a second end of the second locking section to release the disengaged position of the water pipe, a third end of the second locking section is connected to the mounting section, and a limiting space is formed between the limiting protrusion and a portion of the second locking section.

[0019] The above-mentioned optional embodiments of this application achieve the following technical effects: By rotating the first locking section, the relative position between the second end of the first locking section and the second locking section can be changed. The second end of the second locking section has a mechanism for engaging with the second end of the first locking section, together forming a structure for locking the water pipe, realizing the function of locking or releasing the water pipe, and ensuring the stable fixation of the water pipe under different conditions. The second locking section also participates in the formation of the limiting space, working in conjunction with the limiting protrusion to restrict the movement of the water pipe and ensure the stability of the water pipe in a fixed position.

[0020] Furthermore, the second locking section includes: a second locking section body; a limiting section, one end of which is connected to the second locking section body, and the other end of which extends away from the mounting section along the radial direction of the mounting section and toward the end of the mounting section away from the second locking section body, forming a limiting space between the limiting protrusion and the limiting section.

[0021] The above-described optional embodiments of this application achieve the following technical effects: During assembly, the water pipe is first placed in the groove of the second locking section, and then the first locking section is rotated so that the second end of the first locking section engages with the second end of the second locking section, thereby completing the locking of the water pipe. The cooperation between the limiting section and the limiting protrusion ensures that after the water pipe is installed into the drain hole of the vehicle body through the snap fastener, it can maintain a good fixed state even if it encounters vibration or impact during vehicle operation.

[0022] Furthermore, the maximum distance between the end of the limiting segment furthest from the mounting segment body and the outer surface of the mounting segment body is L1, and the maximum distance between the end of the limiting protrusion furthest from the mounting segment body and the outer surface of the mounting segment body is L2, where L1 > L2.

[0023] The above-described optional embodiments of this application achieve the following technical effects: the L1>L2 design ensures that the limiting section protrudes further from the outer surface of the mounting section body than the limiting protrusion. When the water pipe is fixed in the snap-fit, the limiting section can provide a wider radial limit, preventing the seal from swinging or displacing along the axial direction of the mounting section body, thereby enhancing the connection stability of the water pipe and reducing the risk of water pipe loosening or falling off due to vibration or impact. According to another aspect of the embodiments of this application, a vehicle is provided, including the above-described snap-fit ​​structure.

[0024] The embodiments of this application achieve the following technical effects: The vehicle includes a body and a water pipe. The entire snap-fit ​​component, through the setting of a locking structure and a sealing structure, achieves the simultaneous fixation of the water pipe and sealing of the (vehicle leakage hole) hole without adding new mounting holes on the body sheet metal. In practical applications, this snap-fit ​​structure can be used as a pre-installed sub-assembly component, directly integrated with the water pipe 30, and then quickly installed as a whole in the vehicle final assembly stage, which greatly improves the efficiency of the production line and reduces the various costs and risks caused by the installation of independent components.

[0041] In the automotive manufacturing industry, securing and sealing water pipes and holes in the vehicle door sill area is a common technical requirement. Traditional solutions typically include separate plugs and clips. The plugs seal the holes to prevent water or foreign objects from entering the vehicle, while the clips secure the water pipes, ensuring their stability and safety during vehicle operation. However, existing solutions have numerous limitations and drawbacks, especially in multi-model platform production environments.

[0042] 1) Independent plug and clip solution: Currently, the most common solution on the market is an independent plug and clip assembly. The plug is usually a ring-shaped structure made of EPDM material, used to block the sheet metal hole, while the clip is a fixing device used to securely fix the water pipe to the vehicle body. This type of independent component design not only increases the number of parts in the automobile manufacturing process, but also makes the assembly process more complex, requiring multiple operations to complete the fixing of the water pipe and the sealing of the hole.

[0043] 2) Multi-model adaptability challenges: When multiple models are produced on the same production line, different models may have different requirements. This necessitates designing, producing, and storing corresponding plugs and clips for each model, significantly increasing management costs and inventory pressure. Furthermore, if existing parts need to be reused in new models, seamless conversion is often impossible due to differences in hole diameter, further increasing production costs and design complexity.

[0044] 3) Inadequate sealing performance and fixing strength: Existing plugs and clips, being independently designed, struggle to provide both good sealing performance and sufficient fixing strength. Especially when the vehicle travels on bumpy roads or after prolonged use, the independent plugs are prone to loosening, leading to seal failure, while the independent clips may detach due to vibration, failing to effectively secure the water pipe. This can cause problems such as water pipe swaying and leakage, and even threaten vehicle safety.

[0045] 4) High cost of sheet metal derivative processing: In traditional solutions, additional clip holes need to be added to the side sheet metal to install and fix the water pipes. This process involves a series of processes such as stamping and laser cutting, which not only increases the production cost of sheet metal, but also requires additional error prevention measures during the subsequent welding and assembly process to prevent improper or missing clip installation. This further increases the final assembly cost. It is estimated that the cost increase per vehicle can reach more than 660,000 yuan.

[0046] 5) Complex and inefficient assembly process: The installation process for independent plugs and clips is cumbersome, requiring multiple positioning and operations to complete, increasing assembly time and potential human error. Especially on an assembly line, each additional step leads to a decrease in assembly efficiency and also increases the requirements for operators, thus raising labor costs.

[0047] Given the problems with the existing technologies, especially in terms of cost control, assembly efficiency, and functional integration, there is an urgent need for an innovative solution that can meet the expansion needs of multiple vehicle platforms, improve sealing performance and fixing strength, and reduce processing costs and assembly complexity, in order to address the urgent needs of the modern automotive manufacturing industry for efficient, low-cost, and multifunctional integration.

[0048] Combination Figures 1 to 7As shown, a specific embodiment of this application provides a solution.

[0049] The present application provides a snap-fit ​​structure including a snap-fit ​​member 10. One end of the snap-fit ​​member 10 is provided with a locking structure 11 for locking the water pipe 30, and the other end of the snap-fit ​​member 10 is provided with a sealing structure 12 for sealing the leakage hole of the vehicle body.

[0050] Compared to the closest prior art, the entire snap-fit ​​component 10, through the setting of the locking structure 11 and the sealing structure 12, achieves both the fixation of the water pipe 30 and the sealing of the (vehicle leakage hole) hole without the need to add new mounting holes on the vehicle body sheet metal. In practical applications, this snap-fit ​​structure can be used as a pre-installed sub-assembly component, directly integrated with the water pipe 30 (in combination with...). Figure 5 As shown in the figure, it is then quickly installed as a whole during the vehicle assembly stage, which greatly improves the efficiency of the production line and reduces the various costs and risks caused by the installation of independent components.

[0051] Combination Figure 1 and Figure 2 As shown, the locking structure 11 is located at one end of the clip 10 and is used to lock and secure the water pipe 30 in the vehicle. The locking structure 11 can securely and stably fix the water pipe 30 to the vehicle sill or other locations where the water pipe 30 needs to be installed without adding additional holes in the vehicle body panels. The sealing structure 12 is located at the other end of the clip 10 and is used to seal leak holes on the vehicle body, preventing moisture, dust, or other foreign objects from entering the vehicle body and damaging the vehicle's electronic systems or causing corrosion. The sealing structure 12 typically includes EPDM (ethylene propylene diene monomer) foam gaskets or other materials with high elasticity and weather resistance to ensure a reliable seal under various environmental conditions. This design not only improves sealing performance but also reduces the number of individual parts required for assembly, thereby reducing manufacturing costs and simplifying the assembly process.

[0052] Furthermore, the sealing structure 12 includes an mounting section 121 and a sealing element 122. The mounting section 121 is connected to the locking structure 11, and a limiting space 123 is formed between a portion of the mounting section 121 and a portion of the locking structure 11. The mounting section 121 is used for detachable connection with the body leakage hole. The sealing element 122 is connected to the mounting section 121 and is arranged along the circumference of the mounting section 121. The sealing element 122 is disposed within the limiting space 123. When the mounting section 121 is connected to the body leakage hole, the sealing element 122 blocks the body leakage hole.

[0053] The mounting section 121 is connected to the locking structure 11, ensuring that while the water pipe 30 is fixed by the clip 10, it can also form a detachable connection with the body drain hole. A limiting space 123 is formed between the mounting section 121 and the locking structure 11, and the seal 122 is positioned within the limiting space 123. When the mounting section 121 is connected to the body drain hole, the seal 122 is compressed and tightly fits against the hole wall, forming an effective waterproof seal to prevent moisture, dust, and other external substances from entering the body, thereby protecting the vehicle's electronic system and internal components from damage.

[0054] Furthermore, the mounting section 121 includes a mounting section body 1210 and a limiting protrusion 1211. The mounting section body 1210 is connected to the locking structure 11. One end of the limiting protrusion 1211 is connected to the mounting section body 1210, and the other end of the limiting protrusion 1211 extends away from the mounting section body 1210, forming a limiting space 123 between the limiting protrusion 1211 and part of the locking structure 11.

[0055] Combination Figure 2 and Figure 3 As shown, one end of the limiting protrusion 1211 is connected to the mounting section body 1210, while the other end extends outward, forming a limiting space 123 together with part of the locking structure 11. The function of the limiting protrusion 1211 is to provide precise guidance and restriction for the correct position and compression of the seal 122 when the snap-fit ​​is installed at the body leakage hole. This structure can prevent the seal 122 from shifting or being over-compressed during assembly, ensuring that its sealing effect within the limiting space 123 reaches the optimal state. Through the synergistic effect of the limiting protrusion 1211 and the limiting space 123, the stability and sealing performance of the sealing structure 12 are significantly enhanced, making the snap-fit ​​structure more practical and economical while meeting functional requirements.

[0056] Furthermore, the limiting protrusion 1211 is made of an elastic material.

[0057] In this embodiment, the elastic limiting protrusion 1211 can adaptively adjust to the slight differences in orifice diameters. Even if there are manufacturing tolerances in the body leakage hole, the limiting protrusion 1211 can ensure that the sealing structure 12 is in close contact with the hole wall through its own elastic deformation, thereby achieving a more reliable and uniform sealing effect. The limiting protrusion 1211 made of elastic material can effectively reduce friction during installation, making it easier for the snap fastener 10 to be embedded in the body leakage hole. After being squeezed, it elastically returns to its original position and is tightly connected to the hole wall. This design reduces the force required during assembly, improves assembly efficiency, and reduces the risk of component damage due to improper assembly. The elastic material has good shock absorption and impact resistance properties, which helps the snap fastener 10 resist the stress caused by uneven road surfaces and vehicle vibrations during vehicle operation, maintain the stability and integrity of the sealing structure 12, and extend the service life of the overall device.

[0058] Specifically, the limiting protrusion 1211 may be made of, but is not limited to, EPDM rubber, silicone rubber, polyurethane, nitrile rubber or thermoplastic elastomer (TPE).

[0059] Furthermore, there are multiple limiting protrusions 1211, which are arranged at intervals along the circumference of the mounting section body 1210.

[0060] In this embodiment, multiple limiting protrusions 1211 are evenly distributed around the circumference of the mounting section body 1210, ensuring a tight fit of the seal 122 across the entire aperture perimeter, forming a more uniform and stable sealing surface. This multi-point contact design effectively disperses pressure, preventing seal failure due to excessive pressure at a single point, while also enhancing the friction between the seal and the aperture wall, improving the reliability and durability of the seal.

[0061] Combination Figure 3 As shown, there are two limiting protrusions 1211, which are symmetrically arranged to increase the structural strength of the mounting section body 1210, especially under the condition of being subjected to large external pressure or vibration. These limiting protrusions 1211, as reinforcement points, can effectively disperse external forces, reduce the risk of body breakage or deformation, and thus extend the service life of the fastener 10.

[0062] Furthermore, the cross-sectional area of ​​the limiting protrusion 1211 in the axial direction of the mounting section body 1210 is set to gradually decrease in the direction away from the mounting section body 1210.

[0063] Combination Figure 6 and Figure 7As shown, in this embodiment, the cross-sectional area of ​​the limiting protrusion 1211 gradually decreases, forming a cone-shaped structure. When the snap-fit ​​member 10 is installed into the vehicle body's leakage hole, the gradually decreasing cross-sectional area of ​​the limiting protrusion 1211 guides the seal 122 to form a progressive contact with the hole wall, ensuring that the seal 122 can be uniformly compressed after the snap-fit ​​member 10 is fully embedded, forming a tight sealing ring. This design effectively prevents water, gas, or other liquids from leaking from the pores, ensuring good sealing performance.

[0064] Furthermore, the seal 122 is detachably connected to the mounting section 121.

[0065] In one embodiment of this application, when the seal 122 needs to be replaced due to wear, aging, or damage, the detachable connection allows the seal 122 to be replaced separately without replacing the entire snap-fit ​​assembly 10, reducing maintenance costs and time and improving the maintenance efficiency of the device. At the same time, replacing the seal 122 without affecting the structural integrity of the mounting section 121 helps extend the service life of the entire snap-fit ​​assembly 10.

[0066] Furthermore, the seal 122 is integrally formed with the mounting section 121.

[0067] In one embodiment of this application, the integrated design combines the seal 122 and the mounting section 121 into one unit, eliminating seams and connection points between them. During installation and use, the sealing performance or stability will not be affected by loosening or damage at the connection points. This enhanced overall structure improves the reliability of the device.

[0068] Furthermore, the locking structure 11 includes a first locking section 111 and a second locking section 112. The first end of the second locking section 112 is connected to the first end of the first locking section 111. The first locking section 111 is rotatably disposed relative to the second locking section 112. The second end of the first locking section 111 has a locking engagement with the second end of the second locking section 112 to lock the position of the water pipe 30, and the second end of the first locking section 111 has a disengagement from the second end of the second locking section 112 to release the disengaged position of the water pipe 30. The third end of the second locking section 112 is connected to the mounting section 121. A limiting space 123 is formed between the limiting protrusion 1211 and a portion of the second locking section 112.

[0069] Combination Figure 6 and Figure 7As shown, by rotating the first locking section 111, the relative position between the second end of the first locking section 111 and the second locking section 112 can be changed. The second end of the second locking section 112 has a mechanism for engaging with the second end of the first locking section 111, together forming a structure for locking the water pipe, realizing the function of locking or releasing the water pipe 30, and ensuring the stable fixation of the water pipe under different conditions. The second locking section 112 also participates in the formation of the limiting space 123, working in conjunction with the limiting protrusion 1211 to restrict the movement of the water pipe 30 and ensure the stability of the water pipe 30 in the fixed position.

[0070] Furthermore, the second locking section 112 includes a second locking section body 1120 and a limiting section 1121. One end of the limiting section 1121 is connected to the second locking section body 1120, and the other end of the limiting section 1121 extends away from the mounting section 121 along the radial direction of the mounting section 121 and toward the end of the mounting section 121 away from the second locking section body 1120. A limiting space 123 is formed between the limiting protrusion 1211 and the limiting section 1121.

[0071] During assembly, the water pipe 30 is first placed in the groove of the second locking section 112, and then the first locking section 111 is rotated so that the second end of the first locking section 111 engages with the second end of the second locking section 112, thereby locking the water pipe 30. The fit between the limiting section 1121 and the limiting protrusion 1211 ensures that after the water pipe 30 is installed into the drain hole of the vehicle body 40 through the buckle 10, it can maintain a good fixed state even if it encounters vibration or impact during vehicle operation.

[0072] Furthermore, the maximum distance between the end of the limiting segment 1121 away from the mounting segment body 1210 and the outer surface of the mounting segment body 1210 is L1, and the maximum distance between the end of the limiting protrusion 1211 away from the mounting segment body 1210 and the outer surface of the mounting segment body 1210 is L2, wherein L1 > L2.

[0073] The L1>L2 design ensures that the limiting section 1121 protrudes further from the outer surface of the mounting section body 1210 than the limiting protrusion 1211. When the water pipe 30 is secured in the clip 10, the limiting section 1121 provides a wider radial limit, preventing the seal 122 from swinging or displacing along the axial direction of the mounting section body 1210, thereby enhancing the connection stability of the water pipe 30 and reducing the risk of the water pipe 30 loosening or falling off due to vibration or impact.

[0074] Furthermore, the maximum distance between the end of the limiting segment 1121 away from the mounting segment body 1210 and the outer surface of the mounting segment body 1210 is L1, and the maximum distance between the end of the limiting protrusion 1211 away from the mounting segment body 1210 and the outer surface of the mounting segment body 1210 is L2, wherein L1 / L2 > 3.

[0075] The setting of L1 / L2>3 further enables the limiting section 1121 to prevent the seal 122 from swinging or displacing along the axial direction of the installation section body 1210, thereby enhancing the connection stability of the water pipe 30 and reducing the risk of the water pipe 30 loosening or falling off due to vibration or collision.

[0076] According to another aspect of the embodiments of this application, a vehicle is provided, including the above-described snap-fit ​​structure.

[0077] Specifically, the snap-fit ​​structure includes a snap-fit ​​member 10. One end of the snap-fit ​​member 10 is provided with a locking structure 11 for locking the water pipe 30, and the other end of the snap-fit ​​member 10 is provided with a sealing structure 12 for sealing the body leakage hole. The vehicle includes a body 40 and a water pipe 30. The body 40 has a body leakage hole on its sheet metal parts. The snap-fit ​​member 10, by setting the locking structure 11 and the sealing structure 12, achieves both fixing the water pipe 30 and sealing the hole (vehicle leakage hole) without adding new mounting holes to the body sheet metal. In practical applications, this snap-fit ​​structure can be used as a pre-installed sub-assembly component, directly integrated with the water pipe 30 (in combination with...). Figure 5 As shown), and then quickly installed as a whole during the vehicle assembly stage (in combination with...). Figure 1 As shown in the figure, this greatly improves the efficiency of the production line and reduces the various costs and risks caused by the installation of independent components.

[0078] Combination Figure 1 and Figure 2 As shown, the locking structure 11 is located at one end of the clip 10 and is used to lock and secure the water pipe 30 in the vehicle. The locking structure 11 can securely and stably fix the water pipe 30 to the vehicle sill or other locations where the water pipe 30 needs to be installed without adding additional holes in the vehicle body panels. The sealing structure 12 is located at the other end of the clip 10 and is used to seal leak holes on the vehicle body, preventing moisture, dust, or other foreign objects from entering the vehicle body and damaging the vehicle's electronic systems or causing corrosion. The sealing structure 12 typically includes EPDM (ethylene propylene diene monomer) foam gaskets or other materials with high elasticity and weather resistance to ensure a reliable seal under various environmental conditions. This design not only improves sealing performance but also reduces the number of individual parts required for assembly, thereby reducing manufacturing costs and simplifying the assembly process.

[0079] Terminology Explanation

[0080] In this application, "multiple" refers to two or more.

[0081] In this application, unless otherwise expressly defined, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0082] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0083] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0084] Unless otherwise specified, all steps in this application may be performed sequentially or randomly. For example, if the method includes steps A and B, it means that the method may include steps A and B performed sequentially, or it may include steps B and A performed sequentially. For example, if the method may also include step C, it means that step C may be added to the method in any order. For example, the method may include steps A, B, and C, or it may include steps A, C, and B, or it may include steps C, A, and B, etc.
