Description

Technical Field

[0001] This application relates to the field of wearable device design, and more specifically to a host flip structure. Background Technology

[0002] In existing electronic devices, the main unit and the base are typically connected by a long, integrated hinge running through both sides of the main body. While this structure is straightforward in design, it has significant shortcomings in practical applications. Due to limited internal space, the installation of the long hinge requires extremely high assembly standards, increasing the complexity of manufacturing and assembly. Furthermore, if the long hinge experiences localized wear and deformation during long-term use, it must be completely disassembled and replaced, making maintenance inconvenient. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this application is to provide a host flipping structure, which is beneficial to improving the assembly efficiency and maintainability of the rotary connection structure.

[0010] In some embodiments, the mating protrusion is a radially protruding columnar structure, and the mating recess is a groove structure that fits into the mating protrusion. The mating recess has a first insertion hole and a second insertion hole on its opposite side walls along its axial direction.

[0013] In some embodiments, the first limiting portion further includes a connecting segment, which is axially connected between the two partition segments, thereby the connecting segment and the two partition segments together form a U-shaped bent body.

[0014] In some embodiments, the limiting structure further includes an anti-rotation structure, which is provided corresponding to the first through hole and / or the second through hole;

[0015] Wherein, the outer contour of the anti-rotation structure is adapted to at least a portion of the outer contour of the first shaft and / or the second shaft, so that when the first shaft and / or the second shaft is assembled to the first docking structure, at least a portion of the structure is fitted into the anti-rotation structure to prevent the first shaft and / or the second shaft from circumferentially deflecting relative to the first docking structure.

[0016] In some embodiments, the anti-rotation structure includes a limiting groove, which is disposed adjacent to the first through hole, such that the limiting groove and the first through hole together form an integral whole. The outer peripheral wall of the first rotating shaft is provided with a limiting segment that protrudes radially, and the contour of the limiting segment is adapted to the contour of the limiting groove. When the first rotating shaft passes through the first through hole, the limiting segment is embedded in the limiting groove.

[0017] And / or, the outline of the second through hole is a non-circular outline, thereby forming the anti-rotation structure located at the position of the second through hole. The second rotating shaft includes a first segment and a second segment connected in sequence. The outline of the second segment is consistent with the outline of the second through hole. After assembly, the first segment can be rotatably inserted into the second mating structure, and the second segment is inserted into the second through hole.

[0018] In some embodiments, the host flipping structure further includes a fastening structure, which includes a first fastening part and a second fastening part. The first fastening part is disposed on the outer peripheral wall of the first rotating shaft, and the second fastening part is disposed on the first docking structure.

[0022] And / or, the first docking structure is disposed on the base, and the second docking structure is disposed on the device host.

[0023] Compared with the prior art, the host flipping structure provided in this application has at least the following advantages:

[0024] By setting a first and a second rotating shaft separately within the assembly cavity, the rotary connection no longer relies on a long rotating shaft running through the entire structure, thus significantly reducing the requirements for hole position accuracy during assembly and simplifying the assembly process. The first limiting part in the limiting structure can effectively prevent axial movement of the two rotating shafts, ensuring a smooth and stable flipping process; the second limiting part closes the mounting opening in a detachable manner, which not only provides a sealing and protection function but also facilitates later maintenance and replacement.

[0045] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] In existing technologies, a single, long, integrated rotating shaft running through both sides of the main body of the device is commonly used to achieve rotation and flipping between the main unit and the base. While this type of long rotating shaft structure is relatively simple in concept, it has revealed a series of technical defects in practical applications.

[0047] First, due to the compact and complex internal space of electronic equipment, the long rotating shaft needs to precisely penetrate the structures on both sides. This requires extremely high precision in machining the shaft hole positions during assembly, significantly increasing assembly difficulty and process costs. Second, during long-term daily use, the long rotating shaft is prone to stress concentration during repeated rotations. Localized parts may deform or loosen after continuous wear, affecting the overall rotational stability and lifespan of the machine. Furthermore, replacing parts is inconvenient.

[0048] In one embodiment, refer to the appendix to the specification. Figure 1 The present application provides a host flipping structure, which is set in a wearable device. The wearable device includes a host device 4 and a base 3, which are connected by a mating structure.

[0049] Specifically, such as Figures 2 to 4 As shown, the docking structure of the base 3 or the docking structure of the main unit 4 is provided with an assembly cavity 100; wherein, the docking structure with the assembly cavity 100 is the first docking structure 1, and the docking structure without the assembly cavity 100 is the second docking structure 2, so as to facilitate the explanation and clarification of the scope of protection.

[0050] As attached Figures 5 to 7As shown, the assembly cavity 100 extends axially to form a first through hole 101 and a second through hole 102, and has a mounting opening 103 on its side. The second mating structure 2 cooperates with the first mating structure 1 to accommodate the inserted portions of the first rotating shaft 51 and the second rotating shaft 52. During assembly, the first rotating shaft 51 and the second rotating shaft 52 are typically inserted into the assembly cavity 100 sequentially through the mounting opening 103, passing through the first through hole 101 and the second through hole 102 respectively. Then, the limiting structure 6 (described later) provides axial limitation, allowing the ends of the two rotating shafts to simultaneously extend into the corresponding holes of the second mating structure 2, thereby forming a rotational connection between the first mating structure 1 and the second mating structure 2.

[0051] In another assembly method, one of the rotating shafts (such as the second rotating shaft 52) ​​can be selected to enter the assembly cavity 100 through the mounting port 103 and pass through to the second mating structure 2, while the other rotating shaft (such as the first rotating shaft 51) is pre-installed in the first mating structure 1 and directly snaps into the corresponding hole in the second mating structure 2 during assembly. This method is more flexible in actual process layout, especially suitable for situations where space is limited or step-by-step operations are required; in some cases, both rotating shafts can also be selected to be directly inserted into the first mating structure 1 and the second mating structure 2 from the outside.

[0052] It should be noted that assembly gaps are involved in the assembly process. The size of the assembly gaps can be designed according to the actual situation. The main purpose is to effectively compensate for machining and assembly errors during the docking operation, and to ensure that there is a certain margin when docking, so that the ends of the two rotating shafts can be smoothly inserted into the corresponding holes of the second docking structure 2, thereby ensuring the smoothness of the overall assembly process.

[0053] In addition, when the second docking structure 2 is made of plastic or other materials with a certain degree of elasticity, its moderate deformation during the assembly process can be used to assist the insertion of the shaft, and it can be restored to its original shape after assembly.

[0054] Based on the above structure, the host flipping structure also includes a limiting structure 6, such as... Figure 2 and Figure 3 As shown, the limiting structure 6 is disposed within the assembly cavity 100 to ensure the stable positioning of the first rotating shaft 51 and the second rotating shaft 52 during use. The first limiting part 61 extends into the mounting port 103 and is axially arranged between the first rotating shaft 51 and the second rotating shaft 52, effectively limiting their axial displacement. The second limiting part 62 is detachably connected to the first docking structure 1 to close the mounting port 103 and protect the internal structure, ensuring both the stability and reliability of the rotating shafts and providing convenient conditions for subsequent maintenance and replacement.

[0055] Thus, the separate design of the first rotating shaft 51 and the second rotating shaft 52 reduces assembly difficulty and minimizes rotational instability and abnormal noise caused by misalignment. Simultaneously, the limiting structure 6 suppresses axial movement of the rotating shaft, making the flipping process smoother and more stable. Furthermore, the detachable design of the second limiting part 62 allows for localized treatment through the open mounting port 103 when wear or maintenance is required after long-term use, significantly improving maintainability and service life.

[0056] In a further embodiment, the first limiting part 61 can be designed as a sheet or a block according to actual needs. The second limiting part 62 can be connected to the first docking structure 1 by means of a snap-fit ​​structure, a screw fixing structure or a sliding fitting structure, so as to select an appropriate connection method according to the assembly process requirements of different products, and ensure a balance between installation stability and ease of disassembly and assembly.

[0057] In one implementation, the first docking structure 1 is disposed on the base 3, and the second docking structure 2 is disposed on the main unit 4. The main unit 4 achieves a stable rotational connection through the second docking structure 2 that cooperates with the first docking structure 1.

[0058] Specifically, the first docking structure 1, as the main body of the assembly cavity 100, not only houses the main structures of the first rotating shaft 51 and the second rotating shaft 52, but also includes a limit structure 6 and an anti-rotation structure. Therefore, after assembly, the base 3 can provide a reliable support point for the rotation of the main unit 4. Correspondingly, the second docking structure 2 on the main unit 4 mainly forms mating insertion holes or grooves for engaging with the rotating shafts on the first docking structure 1, thereby enabling the main unit to be rotatably mounted on the base 3.

[0059] Understandably, the first docking structure 1 is centrally located on the base 3, so that the main stress point during the flipping motion is located on one side of the base 3. This facilitates the base 3 to maintain overall stability through its own weight and structural strength, while also reducing the complex stress borne by the main unit 4 and extending its service life. Secondly, this embodiment can provide sufficient space utilization for the rational configuration of the main unit flipping structure under the requirements of miniaturization and lightweight design of the equipment, avoiding the increase in the number of parts and processing difficulty caused by having complex docking structures on both sides of the main unit 4 and the base 3.

[0060] In one embodiment, such as Figure 3 and Figure 4 As shown, the docking structure is specifically configured as a docking protrusion 31 and a docking recess 41 that cooperate with each other, and the two are respectively set at the hinge point between the base 3 and the main unit 4.

[0061] The assembly cavity 100 is formed inside the mating protrusion 31, and the first through hole 101 and the second through hole 102 are distributed on opposite sides of the mating protrusion 31. During assembly, the first rotating shaft 51 and the second rotating shaft 52 are inserted through the assembly cavity 100 and pass through the first through hole 101 and the second through hole 102 respectively. Part of their structure further penetrates the mating protrusion 31 and extends into the corresponding mating recess 41, thereby achieving a plug-in fit and rotational connection between the mating protrusion 31 and the mating recess 41.

[0062] The base 3 and the main unit 4 can be respectively equipped with mating protrusions 31 or mating recesses 41 according to specific design requirements, and the two maintain mutual correspondence and matching in structure. Thus, in this design, through the geometric embedding between the mating protrusions 31 and the mating recesses 41, preliminary limiting and positioning can be achieved before the structure is fully positioned by the rotating shaft, allowing the base 3 and the main unit 4 to maintain a relatively stable posture during assembly. Simultaneously, the convex-concave fit provides a self-correcting effect; as the mating protrusion 31 gradually enters the mating recess 41, it can guide the axis of the rotating shaft to align with the through hole to a certain extent, thereby improving the smoothness of assembly.

[0063] Thus, during long-term use of the equipment, the engagement of the mating protrusion 31 and the mating recess 41 not only shares part of the load borne by the rotating shaft, but also prevents relative slippage of the components. In other words, the convex-concave fit adds an extra layer of structural support, making the overall connection more stable and effectively reducing the risk of wear and loosening caused by excessive stress on the rotating shaft.

[0064] In a further embodiment, the shapes of the mating protrusion 31 and the mating recess 41 can be designed according to the equipment space and strength requirements. For example, a cylindrical, elliptical, or polygonal structure with reinforcing ribs can be adopted to improve structural strength and torsional resistance. In another embodiment, the mating clearance between the mating protrusion 31 and the mating recess 41 can be adjusted appropriately to ensure smooth assembly when the shaft is inserted and provide sufficient rotational stability during use.

[0065] In one embodiment, based on the above embodiments, the mating protrusion 31 is designed as a radially protruding columnar structure, while the corresponding mating recess 41 is a grooved structure that fits into it. This interlocking method of the columnar and grooved parts allows a clear spatial fit between the base 3 and the device host 4, improving the limiting effect and guiding function of the structure.

[0066] Furthermore, in the axial direction (axial direction of the shaft) of the mating recess 41, a first insertion hole 411 and a second insertion hole 412 are respectively provided on its opposite side walls, so that the first shaft 51 and the second shaft 52 can enter the mating recess 41 from different holes, forming a double-point support after assembly, which improves the stress stability of the shaft during use.

[0067] Understandably, in this embodiment, on the one hand, the interlocking action of the mating protrusion 31 and the mating recess 41 allows for the initial positioning of the base 3 and the main unit 4 before the rotating shaft is inserted, reducing assembly difficulty; on the other hand, the two insertion holes correspond to the two rotating shafts respectively, enabling the two rotating shafts to achieve independent insertion and engagement in the same groove structure, making the assembly more targeted.

[0068] Moreover, the first insertion hole 411 only needs to be matched with the first through hole 101 and the first rotating shaft 51, and the second insertion hole 412 only needs to be matched with the second through hole 102 and the second rotating shaft 52. If a long rotating shaft design is adopted, the rotating shaft itself must correspond to the size of at least four connection holes, which requires high machining accuracy. Through the design of this application, the machining difficulty can be effectively reduced, and the assembly of the structure can be improved to a certain extent.

[0069] In one embodiment, please refer to the appendix to the specification. Figure 8 The first limiting part 61 includes two partition sections 611, which are respectively fixed to the second limiting part 62, and the extension direction of each partition section 611 is perpendicular to the axial direction. After assembly, the first rotating shaft 51 is located at one end of the assembly cavity 100 and can abut against the corresponding partition section 611 in the axial direction, thereby achieving a clear limiting in that direction; similarly, when the second rotating shaft 52 is located at the other end of the assembly cavity 100, it can also abut against the other partition section 611 in the axial direction, ensuring its stability in the axial position.

[0070] Therefore, by setting the two partition sections 611 relative to each other, the two rotating shafts can be independently limited without adding complex parts, so that the rotating shafts are not prone to axial slippage or loosening in the working state after assembly.

[0071] Furthermore, a preset interval is reserved between the two partition sections 611, providing a margin of movement for the insertion and adjustment of the first rotating shaft 51 and / or the second rotating shaft 52 during assembly. This facilitates the operator in smoothly and accurately guiding the rotating shaft into the corresponding assembly cavity 100 during assembly, avoiding assembly difficulties caused by part tolerances or slight positional deviations. On the other hand, this margin also acts as a buffer during structural operation, preventing excessive constraint caused by temperature changes, stress deformation, and other factors, thereby improving the durability and reliability of the overall connection.

[0072] Understandably, through the design of this embodiment, firstly, the rigid limiting effect of the partition section 611 ensures that the end position of the rotating shaft is always effectively constrained, preventing the problem of axial movement of the split rotating shaft during long-term operation; secondly, by designing a preset interval between the partition sections 611, not only can the production assembly efficiency be improved, but the subsequent maintenance and disassembly needs can also be taken into account.

[0073] In actual implementation, the partition section 611 can be designed as an integral part of the second limiting part 62 according to actual needs, or it can be fixed to the second limiting part 62 by welding, screwing or other means. In addition, the width of the preset interval can be optimized according to factors such as the length of the first rotating shaft 51 and the second rotating shaft 52, so as to minimize the ineffective gap while ensuring reliable limiting.

[0074] Optionally, in some cases, a buffer pad or wear-resistant material may be added to the surface of the partition section 611 to reduce wear caused by direct metal contact and absorb some impact force when needed, thereby further extending the service life of the device.

[0075] Based on the above embodiments, in one embodiment, the first limiting part 61 includes not only two partition sections 611, but also a connecting section 612. The connecting section 612 is connected between the two partition sections 611 in the axial direction, so that the entire first limiting part 61 presents a U-shaped bent structure.

[0076] With this structural arrangement, the two partition sections 611 are no longer completely independent separate components, but are stably connected through the connecting section 612, thereby improving the overall structural strength and resistance to deformation while ensuring the limiting effect. Especially during the repeated rotation and stress of the rotating shaft, the connecting section 612 can play an effective supporting and force-sharing role, preventing the partition section 611 from shifting or loosening due to independent stress.

[0077] Understandably, since the connecting segment 612 connects the two partition segments 611 axially, it forms a continuous frame-like limiting structure 6 after assembly. This not only ensures that the first rotating shaft 51 and the second rotating shaft 52 have reliable limiting support at their respective ends, but also provides better overall stability than two separately set partition segments 611. On the other hand, the presence of the connecting segment 612 can further standardize the size and position of the preset interval, avoiding asymmetrical arrangement between the partition segments 611 due to assembly or processing errors, thereby ensuring a more balanced limiting effect of the rotating shaft in the axial direction.

[0078] Furthermore, the U-shaped structure also facilitates assembly and maintenance. During assembly, the operator only needs to insert the first rotating shaft 51 and the second rotating shaft 52 into the corresponding through hole positions through the mounting port 103. During the pushing process, the partition sections 611 at both ends of the bent body naturally abut against the corresponding rotating shaft to form a limit, preventing the rotating shaft from continuing to slide out of the assembly cavity 100. When disassembly is required, the operator only needs to remove the second limiting part 62 as a whole to release the U-shaped bent body and the rotating shaft together, which not only ensures the reliable limiting of the structure, but also does not cause additional burden to the maintenance operation.

[0079] In one embodiment, the limiting structure 6 further includes an anti-rotation structure disposed in the first through hole 101 and / or the second through hole 102, the outer contour of which is adapted to at least a portion of the outer contour of the first shaft 513 and / or the second shaft.

[0080] When the first shaft 513 and / or the second shaft are inserted into the first mating structure 1 and engage with the corresponding through holes, the anti-rotation structure can form a fitting relationship with the corresponding outer shape of the shaft, thereby effectively preventing the shaft from rotating freely in the circumferential direction relative to the first mating structure 1 after the structure is assembled. This structural arrangement ensures that the shaft maintains a preset posture throughout the machine's operation, thus preventing the rotational stability between the base 3 and the main unit 4 from being affected by shaft rotational misalignment.

[0081] When the user opens, closes, or adjusts the angle, the main unit 4 of the device rotates relative to the base 3 via a pivot. If there is no anti-rotation structure to restrain it, the pivot may deflect circumferentially during the flipping action, causing relative sliding between the pivot and the hole wall of the first docking structure 1. This may result in abnormal noise or wear, and may also affect the overall flipping smoothness and structural stability.

[0082] In this embodiment, by setting an anti-rotation structure through geometric fitting, the rotating shaft is circumferentially locked in a fixed position, ensuring that the force during the rotation process is always transmitted along a preset trajectory, thereby significantly improving the accuracy and reliability of the rotary connection. In specific implementations, the anti-rotation structure can be integrally formed with the first through hole 101 and the second through hole 102 to reduce the number of parts and improve assembly accuracy.

[0083] In one embodiment, based on the above, such as Figure 5 As shown, the anti-rotation structure includes a limiting groove 71, which is arranged adjacent to the first through hole 101, so that the limiting groove 71 and the first through hole 101 together form an integral structure.

[0084] Among them, such as Figure 9 As shown, a limiting segment 511 is provided on the outer peripheral wall of the first rotating shaft 51. The limiting segment 511 protrudes outward in the radial direction, and its outline is adapted to the shape of the limiting groove 71. When the first rotating shaft 51 is inserted into the first through hole 101, the limiting segment 511 can be smoothly embedded into the limiting groove 71, thereby forming a relative fit after assembly, limiting the deflection of the first rotating shaft 51 relative to the first docking structure 1 in the circumferential direction, realizing the anti-rotation positioning of the first rotating shaft 51, and ensuring the center alignment and stability of the base 3 and the main unit 4 during the flipping process.

[0085] Understandably, due to the relative engagement of the limiting segment 511 and the limiting groove 71, the first rotating shaft 51 will not experience circumferential slippage during the rotation of the device host 4. For wearable devices, users can always experience a smooth and stable rotation when frequently adjusting the angle of the device host 4 in daily life.

[0086] For further details, please refer to the appendix. Figure 4 and Figure 11 The outline of the second through hole 102 is designed to be non-circular. The non-circular outline can form an anti-rotation structure that matches the second through hole 102 to prevent unnecessary rotation of the second rotating shaft 52 during use.

[0087] Specifically, the second rotating shaft 52 includes a first segment 521 and a second segment 522 connected in sequence. The outer contour of the second segment 522 is consistent with the contour of the second through hole 102, so that the second segment 522 and the second through hole 102 can form a stable anti-rotation fit in the assembled state.

[0088] During the assembly process, the first segment 521 is rotatably inserted into the second mating structure 2 (inside the second insertion hole 412). In other words, the second insertion hole 412 is a round hole, and the first segment 521 is a cylindrical structure corresponding to the second insertion hole 412, so that the second rotating shaft 52 can rotate. The second segment 522 is inserted into the second through hole 102 to form an anti-rotation structure, thereby limiting and preventing the rotating shaft from rotating at this position.

[0089] Through this design, this application not only ensures that the second rotating shaft 52 can smoothly complete the rotational engagement, but also further avoids the problem caused by the second rotating shaft 52 spinning freely at the position of the second through hole 102, thereby significantly improving the reliability and service life of the overall assembly.

[0090] In practical applications, the aforementioned non-circular contours can be rectangular, elliptical, or polygonal to meet the needs of different structural strengths and assembly precisions.

[0091] In one embodiment, the host flipping structure is further provided with a fastening structure, such as... Figure 6 and Figure 9 As shown, the fastening structure includes a first fastening part 81 and a second fastening part 82, wherein the first fastening part 81 is arranged on the outer peripheral wall of the first rotating shaft 51, and the second fastening part 82 is disposed on the first docking structure 1.

[0092] During the assembly process, the first fastening part 81 and the second fastening part 82 form a fixed connection, so that the first rotating shaft 51 can be constrained in the preset installation position after assembly, avoiding structural loosening caused by axial movement or radial shaking of the rotating shaft.

[0093] It should be noted that the design of the fastening structure enables this application to achieve the main unit's flipping function while further improving the reliability and load-bearing capacity of the shaft connection. In actual use, when the main unit 4 of the equipment is flipped multiple times or operated for a long period of time, the shaft, as the main load-bearing component, is prone to loosening or displacement due to external forces. If there are no effective fastening measures, it will affect the smoothness of the overall flipping action and may even cause the shaft to fall off.

[0094] This application strengthens the connection between the first rotating shaft 51 and the first mating structure 1 by introducing a fastening structure, thereby significantly extending the service life of the equipment. In some specific embodiments, the first fastening part 81 can be a flange, ring, or snap-fit ​​structure provided on the outer periphery of the first rotating shaft 51, while the second fastening part 82 can be a corresponding groove, slot, or clamping member. The two are fixed by means of engagement, threaded fit, or interference fit.

[0095] For example, in one embodiment, the first fastening part 81 adopts an annular flange, and the second fastening part 82 forms a corresponding annular groove on the first mating structure 1. After assembly, the flange and the groove are engaged to achieve firm positioning and fastening.

[0096] Based on the above, please refer to the appendix to the instruction manual. Figure 10In one embodiment, the first rotating shaft 51 includes a first bushing 512 and a first shaft body 513. One end of the first shaft body 513 is inserted into the second docking structure 2. The first bushing 512 is sleeved on the outer periphery of the first shaft body 513 and arranged in the first through hole 101. The first shaft body 513 and the first bushing 512 are both circular in cross-section, so that they can rotate relative to each other, ensuring the smoothness of the host flipping process.

[0097] Furthermore, a first fastening part 81 is provided radially on the first bushing 512, and a sliding groove 1010 adjacent to the first through hole 101 is formed in the first mating structure 1 for inserting the first fastening part 81 during the assembly process.

[0098] Both the first fastening part 81 and the second fastening part 82 include connecting hole structures. During assembly, they can be concentrically positioned and connected to each other by fasteners 83, thereby achieving relative fixation between the first bushing 512 and the first mating structure 1. This embodiment design ensures both the rotational fit between the first shaft 513 and the first bushing 512 and provides effective limiting and fastening effects through the fasteners 83, avoiding loosening of the connection due to prolonged use or frequent rotation.

[0099] It should be noted that in this embodiment, one end of the first shaft 513 is inserted into the second mating structure 2, for example, inserted into the first insertion hole 411 mentioned above. In one implementation, please refer to the appendix. Figure 4 and Figure 10 The first insertion hole 411 can be designed as a non-circular structure, and the insertion end 5131 of the first shaft 513 that mates with it is also machined into the same non-circular contour. This non-circular insertion method can effectively prevent the first shaft 513 from rotating relative to each other at this point, thus avoiding any discomfort in the relative rotation between the main unit 4 and the base 3.

[0100] This embodiment can be combined with the anti-rotation structure in the above embodiment. Therefore, when the main unit 4 and the base 3 are flipped, the rotation process can be concentrated between the first shaft 513 and the first bushing 512. The maintenance cost and difficulty of the components are relatively low, and the flipping performance can be better maintained after long-term use, thereby improving the durability and reliability of the overall structure.

[0101] In one embodiment, such as Figure 2 , Figure 3 , Figure 6 and Figure 8As shown, the second limiting part 62 is a cover plate 621, which is fixedly disposed on the first docking structure 1 and covers the mounting opening 103 to provide reliable limiting and protection for the internal components after assembly. Specifically, the cover plate 621 has at least one first screw hole 6210, and the first docking structure 1 has a second screw hole 11 opposite to the first screw hole 6210 at the corresponding position.

[0102] During assembly, screws 9 can pass through the first screw hole 6210 and be further screwed into the second screw hole 11, thereby securing the cover plate 621 firmly to the first mating structure 1. This ensures a tight fit between the cover plate 621 and the first mating structure 1, preventing loosening during use. Furthermore, as shown in the attached drawings, the cover plate 621 effectively covers the fasteners 83 on its inner side, providing shielding and protection. This prevents the components from being affected by the external environment, such as water, dust, or other impurities, during equipment rotation, thus improving the overall stability and durability of the structure.

[0103] Meanwhile, since the cover plate 621 is an independent component, it can be removed simply by unscrewing screw 9 when maintenance or repair is required. This allows operators to quickly access the internal components and reduces the difficulty of maintenance. Overall, this design not only improves the reliability and safety of the structure during use but also ensures ease of subsequent maintenance.

[0104] In a further embodiment, the cover plate 621 can take on various shapes, such as rectangle, arc or polygon, depending on the different structural layouts. Its edges can be bent or folded according to the shape of the first docking structure 1 to ensure fit and consistency of overall appearance.

[0105] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
