Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic equipment, and more particularly to an assembling unit and a display device. BACKGROUND

[0002] In the related art, a display device includes a plurality of assembling units (such as display units), each assembling unit including a plurality of first components (such as display modules) and a second component (such as a mounting frame), and the plurality of first components and the second component are fixedly connected by magnetic attraction assemblies that magnetically attract each other.

[0003] However, when assembling the first components using the above structure, the first components have a risk of falling, resulting in poor safety of the first components. SUMMARY

[0004] The purpose of the embodiments of the present application is to provide an assembling unit and a display device, aiming to solve the problem of the risk of falling of the first components in the related art.

[0005] To achieve the above-mentioned purpose, according to one aspect of the present application, an assembling unit is provided, including a plurality of first components, a second component, a plurality of first anti-falling pieces, and a second anti-falling piece, the first component is provided with a first connecting piece, the second component is provided with a second connecting piece, the first component is connected with the second component through cooperation of the first connecting piece and the second connecting piece; the first component is provided with at least one first anti-falling piece, and the second anti-falling piece is arranged on the second component; the plurality of first anti-falling pieces are synchronously connected with the second anti-falling piece.

[0006] The plurality of first anti-falling pieces and the second anti-falling piece used in cooperation not only enable the plurality of first components to be firmly mounted on the second component, but also play a role in preventing falling, reduce the risk of falling of the first components, and improve the safety of the first components. At the same time, in the present application, the plurality of first anti-falling pieces and the second anti-falling piece can be synchronously connected, and this structural design has multiple advantages; on the one hand, no separate operation is required for each first anti-falling piece during assembly, which reduces the assembly time and improves the assembly efficiency; on the other hand, the structural design of synchronous connection can ensure that the anti-falling state of each first component is consistent, effectively reducing the risk of falling due to the omission of operation of a single first anti-falling piece. In addition, the plurality of first anti-falling pieces and the second anti-falling piece used in cooperation reduce the number of second anti-falling pieces, and reduce the overall weight and cost of the assembling unit.

[0007] Optionally, one of the first anti-falling piece and the second anti-falling piece is provided with a connecting space, and the other is provided with a connecting structure, the number of the connecting space and the connecting structure is the same, and the plurality of connecting structures are respectively arranged in one-to-one correspondence with the plurality of connecting spaces; the plurality of first anti-falling pieces are respectively synchronously arranged in the plurality of connecting spaces through the plurality of connecting structures and synchronously connected with the second anti-falling piece.

[0008] The use of multiple connection structures and multiple connection spaces not only improves the convenience of synchronous connection of multiple first anti-detachment components and second anti-detachment components, but also reduces the manufacturing difficulty of the first anti-detachment components and the second anti-detachment components, as well as the manufacturing cost of the assembly unit.

[0009] Optionally, multiple first anti-detachment components are spaced apart around a preset axis, and second anti-detachment components are rotatably disposed in the second component around the preset axis, so that multiple connecting structures are synchronously rotated and inserted into multiple connecting spaces.

[0010] When all connecting structures need to be simultaneously inserted into multiple connecting spaces, it is only necessary to rotate the second anti-detachment component around a preset axis on the second component. This drives all connecting structures to align synchronously and insert into the corresponding connecting spaces, thereby achieving synchronous connection between multiple first and second anti-detachment components. Simultaneously, the structural design of the second anti-detachment component rotating around the preset axis allows multiple first and second anti-detachment components to be integrated within the same radial space, contributing to a compact design of the assembly unit and thus saving on the overall volume of the assembly unit.

[0011] Optionally, the first anti-detachment component is a connecting hook. The first anti-detachment component is inserted into the internal space of the connecting hook through a connecting structure and connected to the second anti-detachment component. The internal space of the connecting hook is a connecting space. The connecting space has a hook surface and a hook opening. The hook surface is located on the side of the hook opening away from the reference plane in a preset direction. The preset direction is parallel to the direction of the preset axis. The connecting structure enters and exits the connecting space through the hook opening. The second anti-detachment component has a hook position. When the second anti-detachment component is in the hook position, the connecting structure is inserted into the connecting space and contacts the hook surface to prevent the first anti-detachment component from moving towards the reference plane in the preset direction.

[0012] In one aspect, the connecting structure is in direct contact with the hooking surface after penetrating into the inner space of the connecting hook through the hooking opening, which can prevent the first anti-disengagement element from moving towards the reference surface in the preset direction. This design forms a rigid constraint through surface contact, which can effectively prevent accidental displacement of the first anti-disengagement element in this direction, thereby enhancing the stability of the connection between the first and second anti-disengagement elements and significantly improving the reliability of the anti-disengagement performance. On the other hand, the hooking opening clearly defines the access path of the connecting structure, and in combination with the limiting effect of the hooking surface, the anti-disengagement direction is more accurate, reducing invalid constraints in non-target directions and improving structural stability. In yet another aspect, the core structure of the connecting hook only needs a hooking surface, a hooking opening, and a connecting space, without complex linkage components, which is convenient for manufacturing and processing. At the same time, the cooperation between the connecting structure and the connecting hook relies on geometric positioning, which has higher tolerance for processing tolerances, reducing manufacturing difficulty and cost, and also reducing the risk of jamming during assembly. In addition, the connecting structure enters and exits the connecting space through the hooking opening, combined with the rotation design of the second anti-disengagement element around the preset axis, only the second anti-disengagement element needs to be driven to rotate, which can make all connecting structures enter the corresponding connecting space through the hooking opening and contact the hooking surface simultaneously, without the need for individual alignment operation, greatly improving the assembly and maintenance efficiency.

[0013] Optionally, the second anti-disengagement element also has an entering initial position, when the second anti-disengagement element is in the entering initial position, the connecting structure enters the connecting space through the hooking opening; the assembly unit further comprises a driving element, the driving element is used to push the second anti-disengagement element to switch from the entering initial position to the hooking position.

[0014] The driving element not only enables the second anti-disengagement element to automatically switch from the entering initial position to the hooking position, avoiding the uncertainty of relying on manual alignment or gravity natural positioning; at the same time, it also integrates a locking function, so that the second anti-disengagement element can be stably kept in the hooking position, preventing accidental resetting caused by external forces such as vibration and impact, further reducing the risk of falling of the first component.

[0015] Optionally, the assembly unit further comprises a mounting element, the mounting element is arranged along the preset axis on the second component, the second anti-disengagement element is rotatably sleeved on the mounting element around the preset axis and can reciprocally slide along the preset direction; the driving element is an elastic element, the driving element is sleeved on the mounting element, and the two ends of the driving element are respectively in contact with the second anti-disengagement element and the second component.

[0016] On the one hand, the elastic force provided by the driving element can ensure that the connecting structure is closely attached to the hooking surface, avoiding loosening caused by vibration and impact and enhancing the anti-disengagement reliability. On the other hand, the mounting element is arranged along the preset axis, the second anti-disengagement element is rotatably sleeved and reciprocally slides on the mounting element, and the elastic element is synchronously sleeved on the mounting element; the above three share the same axis and mounting space, avoiding the space occupation of dispersed structures and making the overall layout of the assembly unit more compact.

[0017] Optionally, the mounting member has a first limiting structure, the second anti-dropping member has a second limiting structure, the second limiting structure is located on a side of the reference surface in the preset direction, and one end of the driving member is in contact with the second limiting structure; when the connecting structure is located outside the connecting space, the driving member applies a pushing force to the second limiting structure, and the first limiting structure blocks the second limiting structure from moving towards the side away from the reference surface.

[0018] The above structure design balances mechanical limiting and elastic force, avoids the second anti-dropping member from moving or deviating due to elastic force in a non-working state, significantly enhances the structural stability of the second anti-dropping member, and effectively reduces the risk of the second anti-dropping member falling off the mounting member or the second component.

[0019] Optionally, one of the second anti-dropping member and the second component is provided with a guide protrusion, and the other is provided with a guide groove around the preset axis, and the guide protrusion is arranged in the guide groove.

[0020] On the one hand, the guide groove is arranged around the preset axis, and the trajectory thereof matches the rotating path of the second anti-dropping member; when the guide protrusion is arranged in the guide groove, the movement direction of the second anti-dropping member can be restricted, so that the second anti-dropping member can only rotate circumferentially around the preset axis, and radial deviation or skewing caused by assembly error, vibration and other factors can be avoided. On the other hand, the guide protrusion and the guide groove used in cooperation provide a positioning reference for the initial installation of the second anti-dropping member: during assembly, the guide protrusion only needs to be aligned with the guide groove and arranged therein, so that the coaxiality of the second anti-dropping member and the preset axis can be ensured, and subsequent rotating jamming caused by installation skewing can be avoided.

[0021] Optionally, the guide protrusion comprises a guide body and a limiting body, the limiting body is arranged on the guide body, the guide body is arranged on the second anti-dropping member, and the projection of the limiting body on the projection surface of the second anti-dropping member covers the projection of the guide body on the projection surface of the second anti-dropping member; the guide groove comprises a first guide groove segment and a limiting groove segment arranged in sequence around the preset axis and in communication with each other, the guide protrusion is used for reciprocating sliding in the first guide groove segment in the preset direction, the guide body is used for reciprocating sliding in the limiting groove segment in the preset direction, and the groove wall of the limiting groove segment is used for blocking the limiting body from entering or leaving the limiting groove segment in the preset direction; during the process that the second anti-dropping member switches from the initial position to the hooking position, the guide protrusion slides in the first guide groove segment in the preset direction; during the process that the second anti-dropping member enters from outside the connecting space into the connecting space, the guide body slides in the limiting groove segment around the preset axis, and the limiting body is located outside the limiting groove segment.

[0022] The guide protrusion and the first guide groove segment used in cooperation provide a guiding effect for the sliding of the guide protrusion; at the same time, the guide protrusion, the first guide groove segment and the limiting groove segment used in cooperation also have a limiting effect, so that the connecting structure can only switch from the initial position to the hooking position, and the reliability of the connecting operation of the first anti-dropping member and the second anti-dropping member is improved.

[0023] Optionally, the guide groove further comprises a second guide groove segment, the first guide groove segment, the limiting groove segment and the second guide groove segment are sequentially arranged and communicated around the preset axis, and the guide protrusion is used for reciprocally sliding in the second guide groove segment along the preset axis; the second anti-dropping piece further has an external initial position, when the second anti-dropping piece is in the external initial position, the connecting structure is located outside the connecting space, and the guide protrusion can slide in the second guide groove segment along the preset direction.

[0024] In one aspect, the structure design that the first guide groove segment, the limiting groove segment and the second guide groove segment are sequentially communicated allocates independent guide paths for different action stages of the second anti-dropping piece: when the second anti-dropping piece is in the external initial position, the guide protrusion slides in the second guide groove segment along the preset direction, ensuring the axial stability of the anti-dropping piece in the non-working state and avoiding accidental displacement due to vibration; in the process that the second anti-dropping piece enters from outside the connecting space into the connecting space, the guide body rotates in the limiting groove segment, and the limiting body slides outside the limiting groove segment, thereby restricting the rotation track of the second anti-dropping piece; when the second anti-dropping piece is in the hooking position, the guide protrusion slides in the first guide groove segment, thereby completing the hooking action. The above segmented guide mechanism makes the track of each movement stage independently controllable, avoids mutual interference of different actions, and greatly improves the operation accuracy. In another aspect, when the second anti-dropping piece is in the external initial position, the connecting structure is located outside the connecting space, and at this time, the guide protrusion can slide in the second guide groove segment; this structure design provides guide constraint for the non-working reference position of the anti-dropping piece, and ensures that the second anti-dropping piece can be stably reset to the same initial position after each separation.

[0025] Optionally, the first connecting piece and the second connecting piece are magnetically attracted to each other; and / or, one of the first component and the second component is provided with a connecting rope, and the other is provided with a connecting hole, the connecting rope being hooked into the connecting hole.

[0026] The first connecting piece and the second connecting piece used in cooperation not only can realize the main connection function of the first component and the second component, but also facilitate the separation of the first component and the second component. The connecting rope and the connecting hole used in cooperation not only have simple structure, low cost and strong adaptability, but also are convenient to operate. In addition, the connecting rope and the connecting hole can also be used as redundant connection and play the role of anti-lost insurance. In addition, the flexible property of the connecting rope can realize buffer protection and reduce damage between components caused by collision or pulling.

[0027] According to another aspect of the present application, a display device is provided, comprising a plurality of the above assembly units, the first component in the assembly unit being a display module, and the second component in the assembly unit being a mounting frame.

[0028] When a single display module malfunctions, the locking can be quickly released by separating the first connector from the second connector and the first anti-detachment component from the second anti-detachment component on the corresponding assembly unit, allowing the faulty display module to be disassembled individually without disassembling the entire assembly unit.

[0029] The beneficial effects of the assembly unit provided in this application are as follows: the multiple first anti-detachment components and the second anti-detachment component used in conjunction not only serve to prevent detachment and reduce the risk of the first component falling off, but also improve the safety of the first component. Furthermore, in this application, the multiple first anti-detachment components and the second anti-detachment component can be synchronously connected, a structural design with multiple advantages. On the one hand, it eliminates the need for individual operation of each first anti-detachment component during assembly, reducing assembly time and improving assembly efficiency. On the other hand, the synchronous connection design ensures that the anti-detachment state of each first component is consistent, effectively reducing the risk of falling due to the omission of operation of a single first anti-detachment component. In addition, the use of multiple first anti-detachment components and the second anti-detachment component reduces the number of second anti-detachment components, thus reducing the overall weight and cost of the assembly unit.

However, when assembling the first component using the above structure, the first component has the risk of falling, resulting in poor safety of the first component.

[0053] Reference Figures 1 to 7 In order to solve the above problems, according to one aspect of the present application, the embodiments of the present application provide an assembly unit, which includes a plurality of first components 100, a second component 200, a plurality of first anti-falling components 300 and a second anti-falling component 400. The first component 100 is provided with a first connecting piece 110, the second component 200 is provided with a second connecting piece 210, and the first component 100 is connected with the second component 200 through cooperation of the first connecting piece 110 and the second connecting piece 210. The first component 100 is provided with at least one first anti-falling component 300, and the second anti-falling component 400 is arranged on the second component 200. The plurality of first anti-falling components 300 are used to be connected with the second anti-falling component 400 synchronously.

[0054] In the embodiments of the present application, the first component 100 is a display module, the second component 200 is a mounting frame, and the assembly unit is a display unit. It can be understood that the first component 100 can also be a heat dissipation module, the second component 200 is a mounting bracket, and the assembly unit is a heat dissipation unit. Alternatively, the first component 100 can also be a camera module, the second component 200 is a mounting bracket, and the assembly unit is a camera unit. The number of the first components 100 is two, and the two first components 100 are arranged at intervals along the length direction of the first component 100. It can be understood that the number of the first components 100 can also be three, four or more, which is not limited here according to actual needs.

[0055] The first connecting piece 110 can be a connecting screw, and the second connecting piece 210 is a connecting screw hole. The first connecting piece 110 can also be a connecting column, and the second connecting piece 210 is a connecting hole 810 for the connecting column to be inserted with interference. The first anti-disengagement piece 300 is fixedly installed on the corresponding first component 100 by a connecting screw, and each first component 100 is provided with one anti-disengagement piece. It can be understood that the number of the first anti-disengagement pieces 300 provided on each first component 100 can also be two, three or more. The second anti-disengagement piece 400 is fixedly installed on the second component 200 by a connecting screw. The first anti-disengagement piece 300 can be a protrusion with a hole, and the second anti-disengagement piece 400 can be an anti-disengagement rod penetrating all the first anti-disengagement pieces 300. A plurality of first anti-disengagement pieces 300 are synchronously connected with the second anti-disengagement piece 400 by synchronously inserting the second anti-disengagement piece 400 into the holes of all the first anti-disengagement pieces 300. Alternatively, the first anti-disengagement piece 300 can be an iron sheet, and the second anti-disengagement piece 400 can be a permanent magnet. A plurality of first anti-disengagement pieces 300 are synchronously connected with all the first anti-disengagement pieces 300 by the second anti-disengagement piece 400 synchronously approaching all the first anti-disengagement pieces 300 and magnetically attracting all the first anti-disengagement pieces 300.

It can also be placed horizontally, that is, the length direction of the first component 100 is parallel to the horizontal direction. It can also be placed obliquely, that is, the length direction of the first component 100 is arranged at an angle with the vertical direction and the horizontal direction.

[0057] The plurality of first anti-dropping pieces 300 and the second anti-dropping piece 400 used in cooperation not only enable the plurality of first components 100 to be firmly mounted on the second component 200, but also play a role in preventing falling, reduce the risk of falling of the first component 100, and improve the safety of the first component 100. At the same time, in the present application, the plurality of first anti-dropping pieces 300 and the second anti-dropping piece 400 can be synchronously connected, and this structural design has multiple advantages. On the one hand, it is not necessary to operate each first anti-dropping piece 300 individually during assembly, which reduces assembly time and improves assembly efficiency. On the other hand, the synchronous connection design can ensure that the anti-dropping state of each first component 100 is consistent, effectively reducing the risk of falling due to the omission of the operation of a single first anti-dropping piece 300. In addition, the plurality of first anti-dropping pieces 300 and the second anti-dropping piece 400 used in cooperation reduce the number of second anti-dropping pieces 400, and reduce the overall weight and cost of the assembly unit.

[0058] With reference to Figures 5 to 9 In an embodiment, one of the first anti-dropping piece 300 and the second anti-dropping piece 400 is provided with a connection space 310, and the other is provided with a connection structure 410. The number of connection spaces 310 and the number of connection structures 410 are the same, and a plurality of connection structures 410 are respectively arranged in one-to-one correspondence with a plurality of connection spaces 310. A plurality of first anti-dropping pieces 300 are respectively synchronously inserted into a plurality of connection spaces 310 through a plurality of connection structures 410 to be synchronously connected with the second anti-dropping piece 400.

[0059] In the present embodiment, the first anti-dropping piece 300 is provided with a connection space 310, and the number of connection spaces 310 is the same as the number of first anti-dropping pieces 300. The connection structure 410 is a connecting protruding column, and a plurality of connection structures 410 are arranged at intervals around a predetermined axis on the second anti-dropping piece 400. A plurality of connection structures 410 can be synchronously released by pressing the release switch on the second anti-dropping piece 400, so as to be synchronously inserted into a plurality of connection spaces 310. It can be understood that the first anti-dropping piece 300 can also be provided with a connection structure 410, and the number of connection structures 410 is the same as the number of first anti-dropping pieces 300. The second anti-dropping piece 400 is provided with a plurality of connection spaces 310. In addition, in order to facilitate manufacturing and processing, the plurality of connection structures 410 and the second anti-dropping piece 400 are an integral part.

[0060] The plurality of connection structures 410 and the plurality of connection spaces 310 used in cooperation not only improve the convenience of synchronous connection of the plurality of first anti-dropping pieces 300 and the second anti-dropping piece 400, but also reduce the manufacturing difficulty of the first anti-dropping piece 300 and the second anti-dropping piece 400 and the manufacturing cost of the assembly unit.

[0061] With reference to Figures 5 to 12In an embodiment, the plurality of first anti-disengagement members 300 are arranged at intervals around the preset axis, and the second anti-disengagement member 400 is arranged to rotate around the preset axis on the second component 200, so that the plurality of connecting structures 410 are synchronously arranged to pass through the plurality of connecting spaces 310.

[0062] In the embodiment, the number of the first anti-disengagement members 300 is two, and the two first anti-disengagement members 300 are arranged on the two first components 100 respectively; the plurality of first anti-disengagement members 300 are arranged at intervals around the second anti-disengagement member 400, and the first anti-disengagement members 300 can be anti-disengagement hooks. The connecting space 310 is the internal space of the first anti-disengagement member 300. After the connecting structure 410 passes through the connecting space 310, the anti-disengagement plate or the anti-disengagement tongue on the first anti-disengagement member 300 blocks the connecting structure 410 from disengaging from the connecting space 310.

[0063] When all the connecting structures 410 need to be synchronously arranged to pass through the plurality of connecting spaces 310, only the second anti-disengagement member 400 needs to be driven to rotate around the preset axis on the second component 200, so that all the connecting structures 410 are synchronously arranged to align and pass through the corresponding connecting spaces 310, thereby realizing the synchronous connection of the plurality of first anti-disengagement members 300 and the second anti-disengagement member 400.

[0064] Meanwhile, the structure design that the second anti-disengagement member 400 is arranged to rotate around the preset axis enables the plurality of first anti-disengagement members 300 and the second anti-disengagement member 400 to be integrated in the same radial space, which is helpful to realize the compact design of the assembly unit, thereby saving the overall volume of the assembly unit.

[0065] Reference Figures 5 to 12 In an embodiment, the first anti-disengagement member 300 is a connecting hook, and the first anti-disengagement member 300 is connected with the second anti-disengagement member 400 by the connecting structure 410 passing through the internal space of the connecting hook, and the internal space of the connecting hook is the connecting space 310. The connecting space 310 has a hooking surface 311 and a hooking opening 312. The hooking surface 311 is located on the side of the hooking opening 312 away from the reference surface in the preset direction, and the preset direction is parallel to the direction in which the preset axis is located. The connecting structure 410 enters and exits the connecting space 310 through the hooking opening 312.

[0066] The second anti-disengagement member 400 has a hooking position. When the second anti-disengagement member 400 is in the hooking position, the connecting structure 410 passes through the connecting space 310 and contacts the hooking surface 311, so as to block the first anti-disengagement member 300 from moving towards the reference surface in the preset direction.

[0067] In the embodiment, the plurality of connecting structures 410 are arranged at intervals around the preset axis on the second anti-disengagement member 400. The reference surface is a plane arranged on the side of the first component 100 away from the second component 200 in the preset direction. In addition, the directions in which the hooking openings 312 of the two first anti-disengagement members 300 face are oppositely arranged.Figure 1 The second anti-disengagement piece 400 in the hooking position.

[0068] In one aspect, the connecting structure 410 enters the inner space of the connecting hook through the hooking opening 312 and directly contacts the hooking surface 311, which can prevent the first anti-disengagement piece 300 from moving in the preset direction towards the reference surface. This design forms a rigid constraint through surface contact, which can effectively prevent accidental displacement of the first anti-disengagement piece 300 in this direction, thereby enhancing the stability of the connection between the first anti-disengagement piece 300 and the second anti-disengagement piece 400 and significantly improving the reliability of the anti-disengagement performance.

[0069] On the other hand, the hooking opening 312 defines the access path of the connecting structure 410, and in combination with the limiting effect of the hooking surface 311, the anti-disengagement direction is more accurate, the invalid constraint in the non-target direction is reduced, and the structural stability is improved.

[0070] On the other hand, the core structure of the connecting hook only needs the hooking surface 311, the hooking opening 312, and the connecting space 310, without complex linkage components, which is convenient for manufacturing and processing. At the same time, the cooperation between the connecting structure 410 and the connecting hook relies on geometric positioning, which has higher tolerance for processing tolerances, reduces the manufacturing difficulty and cost, and also reduces the risk of jamming during assembly.

[0071] In addition, the connecting structure 410 enters and exits the connecting space 310 through the hooking opening 312, and in combination with the rotation design of the second anti-disengagement piece 400 around the preset axis, only the second anti-disengagement piece 400 needs to be driven to rotate, which can make all connecting structures 410 enter the corresponding connecting space 310 through the hooking opening 312 and contact the hooking surface 311 simultaneously, without the need for individual alignment operation, which greatly improves the assembly and maintenance efficiency.

[0072] Referring to Figures 5 to 12 In one embodiment, the second anti-disengagement piece 400 also has an entering initial position, when the second anti-disengagement piece 400 is in the entering initial position, the connecting structure 410 enters the connecting space 310 through the hooking opening 312; the assembly unit further includes a driving member 500, which is used to push the second anti-disengagement piece 400 from the entering initial position to the hooking position.

[0073] In this embodiment, when the second anti-disengagement piece 400 is in the entering initial position, the connecting structure 410 has just entered the connecting space 310 through the hooking opening 312, and at this time the connecting structure 410 has not moved towards the hooking surface 311. The driving member 500 can be a manually driven component (such as a manual wheel, a manual lever, a manual push rod), an automatically driven component (a motor + gear set, an air cylinder, a linkage mechanism), or an elastic driving component (such as a spring).

[0074] When the second anti-falling piece 400 is connected with the first anti-falling piece 300, the operation steps are divided into two stages: first, the connecting structure 410 arranged on the second anti-falling piece 400 is made to enter the connecting space 310 through the hooking opening 312, at this time, the second anti-falling piece 400 is in an entering initial position; then, the connecting structure 410 is driven by the driving piece 500 to contact the hooking surface 311, so that the second anti-falling piece 400 is switched from the entering initial position to the hooking position; the above step-by-step operation does not need to consider the alignment and locking at the same time in the process of the connecting structure 410 penetrating, which simplifies the assembly process and reduces the operation threshold.

[0075] The driving piece 500 arranged can not only automatically switch the second anti-falling piece 400 from the entering initial position to the hooking position, but also avoid the uncertainty of relying on manual alignment or gravity natural alignment; at the same time, the driving piece 500 also integrates the locking function, so that the second anti-falling piece 400 can be stably kept in the hooking position, preventing accidental resetting caused by external forces such as vibration and impact, and further reducing the risk of falling of the first part 100.

[0076] Reference Figures 5 to 12 In an embodiment, the assembly unit further comprises a mounting piece 600, the mounting piece 600 is arranged along a preset axis on the second part 200, the second anti-falling piece 400 is rotatably sleeved on the mounting piece 600 around the preset axis and can reciprocally slide along a preset direction; the driving piece 500 is an elastic piece, the driving piece 500 is sleeved on the mounting piece 600, and two ends of the driving piece 500 are respectively in contact with the second anti-falling piece 400 and the second part 200.

[0077] In the embodiment, the second anti-falling piece 400 is provided with a mounting through hole along the preset axis, and the mounting piece 600 is arranged in the mounting through hole; the mounting piece 600 is a mounting screw, and the second part 200 is provided with a screw hole, and the mounting piece 600 is screwed into the screw hole.

[0078] When the second anti-falling piece 400 is connected with the first anti-falling piece 300, the operation process is as follows: first, the second anti-falling piece 400 is pressed towards the reference surface along the preset direction, in this process, the driving piece 500 is compressed under force; then, the second anti-falling piece 400 is rotated around the preset axis, in this process, the connecting structure 410 will penetrate into the connecting space 310 through the hooking opening 312, at this time, the second anti-falling piece 400 is in an entering initial position; then, the second anti-falling piece 400 is released, the connecting structure 410 moves towards the hooking surface 311 under the elastic restoring force of the driving piece 500, and stops moving until it contacts the hooking surface 311, at this time, the second anti-falling piece 400 is in a hooking position.

[0079] When the first anti-disengagement piece 300 is separated from the second anti-disengagement piece 400, the second anti-disengagement piece 400 only needs to be pushed to approach the reference surface along the preset direction, so that the connecting structure 410 is disengaged from the hooking surface 311; then the second anti-disengagement piece 400 is driven to rotate around the preset axis, and the connecting structure 410 can be rotated out of the connecting space 310 through the hooking opening 312.

[0080] The entire connection and separation process described above does not need tool assistance, is simple and convenient to operate, and greatly shortens the time for installing, maintaining or replacing the first component 100.

[0081] In one aspect, the elastic force provided by the driving piece 500 can ensure that the connecting structure 410 is tightly combined with the hooking surface 311, avoid loosening caused by vibration and impact, and enhance the anti-disengagement reliability.

[0082] On the other hand, the mounting piece 600 is arranged along the preset axis, the second anti-disengagement piece 400 is rotationally sleeved and reciprocally slides on the mounting piece 600, and the elastic piece is synchronously sleeved on the mounting piece 600; the three share the same axis and mounting space, which avoids the space occupation of the dispersed structure and makes the overall layout of the assembly unit more compact.

[0083] Referring to Figures 9 to 12 In one embodiment, the mounting piece 600 has a first limiting structure 620, the second anti-disengagement piece 400 has a second limiting structure 420, the second limiting structure 420 is located on the side of the second anti-disengagement piece 400 that approaches the reference surface in the preset direction, and one end of the driving piece 500 is in contact with the second limiting structure 420; when the connecting structure 410 is located outside the connecting space 310, the driving piece 500 applies a pushing force to the second limiting structure 420, and the first limiting structure 620 blocks the second limiting structure 420 from moving toward the side of the second anti-disengagement piece 400 that is away from the reference surface.

[0084] In the embodiment, the first limiting structure 620 is a limiting cap, the mounting piece 600 includes a mounting body 610 and the first limiting structure 620, the first limiting structure 620 is coaxially arranged with the mounting body 610 and located on the side of the mounting body 610 that is away from the second component 200, and the diameter of the first limiting structure 620 is greater than that of the mounting body 610; the second limiting structure 420 is a limiting ring, the second limiting structure 420 is located in the mounting through hole, the second limiting structure 420 is provided with a limiting hole, and the mounting body 610 is arranged in the limiting hole.

[0085] When the connecting structure 410 does not enter the connecting space 310, the driving member 500 always applies an elastic pushing force to the second anti-falling member 400 away from the reference surface; at this time, the first limiting structure 620 directly offsets the elastic pushing force of the driving member 500 by blocking the second limiting structure 420 from moving away from the reference surface, thereby stably limiting the second anti-falling member 400 on the second component 200. The above structure design balances mechanical limiting and elastic force, avoids the second anti-falling member 400 from moving or deviating due to the elastic pushing force in a non-working state, significantly enhances the structural stability of the second anti-falling member 400, and effectively reduces the risk of the second anti-falling member 400 falling from the mounting member 600 or the second component 200.

[0086] With reference to Figure 9 and Figures 12 to 15 In an embodiment, one of the second anti-falling member 400 and the second component 200 is provided with a guide protrusion 430, and the other is provided with a guide groove 220 around a preset axis, and the guide protrusion 430 is inserted into the guide groove 220.

[0087] In this embodiment, the guide protrusion 430 is arranged on the second anti-falling member 400 and located on the side of the second anti-falling member 400 close to the reference surface; and the guide groove 220 is arranged on the second component 200. It can be understood that the second component 200 can also be provided with the guide protrusion 430, and the guide groove 220 is arranged on the second anti-falling member 400. In addition, in order to facilitate manufacturing and processing, the guide protrusion 430 and the second anti-falling member 400 are an integral part.

[0088] On the one hand, the guide groove 220 is arranged around a preset axis, and the trajectory thereof matches the rotation path of the second anti-falling member 400; when the guide protrusion 430 is inserted into the guide groove 220, the movement direction of the second anti-falling member 400 can be constrained, so that the second anti-falling member 400 can only rotate circumferentially around the preset axis, thereby avoiding radial deviation or skewing due to factors such as assembly error and vibration.

[0089] On the other hand, the guide protrusion 430 and the guide groove 220 used in cooperation provide a positioning reference for the initial installation of the second anti-falling member 400: during assembly, the guide protrusion 430 only needs to be aligned with the guide groove 220 and inserted, so as to ensure the coaxiality of the second anti-falling member 400 and the preset axis, thereby avoiding subsequent rotation jamming due to installation skewing.

[0090] In addition, in order to ensure the smoothness of rotation, the number of guide protrusions 430 is two, and the two guide protrusions 430 are arranged at intervals around the preset axis; the number of guide grooves 220 is the same as that of the guide protrusions 430, and the two guide grooves 220 are arranged at intervals around the preset axis, the arc of the guide groove 220 is less than 180°, and the two guide protrusions 430 are respectively inserted into the two guide grooves 220.

[0091] With reference to Figure 9 And Figures 12 to 15 In an embodiment, the guide protrusion 430 comprises a guide body 431 and a limiting body 432, the limiting body 432 is arranged on the guide body 431, the guide body 431 is arranged on the second anti-falling member 400, the limiting body 432 projects to the projection face of the second anti-falling member 400 and covers the projection face of the guide body 431 to the second anti-falling member 400; the guide groove 220 comprises a first guide groove segment 221 and a limiting groove segment 222 which are arranged in sequence and communicate with each other around the preset axis, the guide protrusion 430 is used for reciprocating sliding in the first guide groove segment 221 along the preset direction, the guide body 431 is used for reciprocating sliding in the limiting groove segment 222 along the preset direction, and the groove wall of the limiting groove segment 222 is used for blocking the limiting body 432 from entering or leaving the limiting groove segment 222 along the preset direction.

[0092] In the process of switching the second anti-falling member 400 from the initial position to the hooking position, the guide protrusion 430 slides in the first guide groove segment 221 along the preset direction; in the process of entering the connecting space 310 from outside the connecting space 310, the guide body 431 slides in the limiting groove segment 222 around the preset axis, and the limiting body 432 is located outside the limiting groove segment 222.

[0093] In the embodiment, the guide body 431 is a guide rod, the limiting body 432 is located on the side of the guide body 431 away from the second anti-falling member 400 and is arranged coaxially with the guide body 431, and the diameter of the limiting body 432 is greater than the diameter of the guide body 431; the groove width of the first guide groove segment 221 is greater than the diameter of the limiting body 432, the groove width of the limiting groove segment 222 is greater than the diameter of the guide body 431 and less than the diameter of the limiting body 432. In addition, the groove bottom of the guide groove 220 is provided with a sliding groove 230 extending to the outside of the second component 200, the sliding groove 230 is arranged around the preset axis, and the groove width of the sliding groove 230 is greater than the diameter of the limiting body 432, so that the limiting body 432 can slide in the sliding groove 230 around the preset direction.

[0094] When the second anti-falling member 400 enters the connecting space 310 from outside the connecting space 310, the guide body 431 slides in the limiting groove segment 222 around the preset axis, and the limiting body 432 is blocked outside by the groove wall of the limiting groove segment 222; this structural design restricts the second anti-falling member 400 to complete the rotating action first, effectively avoids the second anti-falling member 400 from rebounding towards the direction away from the reference face under the action of the driving member 500, and ensures the smooth operation of the operation of the connecting structure 410 into the connecting space 310.

[0095] After the second anti-dropping piece 400 is switched to the initial position, the guide protrusion 430 slides in the first guide groove section 221 under the driving of the driving piece 500 towards the side away from the reference surface; the guide protrusion 430 and the first guide groove section 221 are used in cooperation to provide a guide for the sliding of the guide protrusion 430; meanwhile, the guide protrusion, the first guide groove section 221 and the limiting groove section 222 used in cooperation also play a limiting role, ensuring that the connecting structure 410 can only be switched from the initial position to the hooking position, thereby improving the reliability of the connecting operation of the first anti-dropping piece 300 and the second anti-dropping piece 400.

[0096] With reference to Figure 9 and Figures 12 to 15 In an embodiment, the guide groove 220 further comprises a second guide groove section 223, the first guide groove section 221, the limiting groove section 222 and the second guide groove section 223 are sequentially arranged around the preset axis and are in communication with each other, and the guide protrusion 430 is used for reciprocally sliding in the second guide groove section 223 along the preset axis.

[0097] The second anti-dropping piece 400 further has an external initial position, when the second anti-dropping piece 400 is in the external initial position, the connecting structure 410 is located outside the connecting space 310, and the guide protrusion 430 can slide in the second guide groove section 223 along the preset direction.

[0098] In the embodiment, the groove width of the second guide groove section 223 is greater than the diameter of the limiting body 432, and the sliding groove 230 is in communication with the second guide groove section 223. Figure 2 The second anti-dropping piece 400 in the external initial position, Figure 10 The second anti-dropping piece 400 in the external initial position.

[0099] In one aspect, the structure design that the first guide groove section 221, the limiting groove section 222 and the second guide groove section 223 are sequentially in communication allocates independent guide paths for different action stages of the second anti-dropping piece 400: when the second anti-dropping piece 400 is in the external initial position, the guide protrusion 430 slides in the second guide groove section 223 along the preset direction, ensuring the axial stability of the anti-dropping piece in the non-working state and avoiding accidental displacement due to vibration and the like; in the process that the second anti-dropping piece 400 enters from outside the connecting space 310 to inside the connecting space 310, the guide body 431 rotates in the limiting groove section 222, and the limiting body 432 slides outside the limiting groove section 222, thereby constraining the rotation track of the second anti-dropping piece 400; when the second anti-dropping piece 400 is in the hooking position, the guide protrusion 430 slides in the first guide groove section 221, thereby completing the hooking action. The above segmented guide mechanism makes the track of each movement stage independently controllable, avoids mutual interference of different actions, and greatly improves the operation accuracy.

[0100] In another aspect, when the second anti-disengagement member 400 is in the external initial position, the connecting structure 410 is located outside the connecting space 310, and the guide protrusion 430 can slide in the second guide groove segment 223; this structure design provides guide constraint for the non-working reference position of the anti-disengagement member, and ensures that the second anti-disengagement member 400 can be stably reset to the same initial position after each separation.

[0101] With reference to Figure 3 and Figure 4 In an embodiment, the first connecting member 110 and the second connecting member 210 are magnetically attracted to each other.

[0103] The first connecting member 110 and the second connecting member 210 used in cooperation not only can realize the main connecting function of the first component 100 and the second component 200, but also facilitate the separation of the first component 100 and the second component 200.

[0104] In addition, in order to strengthen the connecting strength of the first component 100 and the second component 200, the number of the first connecting member 110 is multiple, and the multiple first connecting members 110 are arranged at intervals; the number of the second connecting member 210 is the same as that of the first connecting member 110, and the multiple second connecting members 210 are arranged in one-to-one correspondence with the multiple first connecting members 110.

It can be understood that the connecting rope 700 can also be hooked into the connecting hole 810 by knotting fixation or hole winding fixation, etc.

In addition, the connecting rope 700 and the connecting hole 810 can also be used as a redundant connection to prevent loss and play a role of insurance. In addition, the flexible characteristic of the connecting rope 700 can realize buffer protection and reduce damage caused by collision or pulling between components.

[0109] In the embodiment, the connecting seat 800 is pivotally connected to the first component 100 through a pivot shaft. When the connecting seat 800 is in the use position, the extension direction of the connecting hole 810 is parallel to the preset direction, and at this time, the connecting hook can be directly inserted into the connecting hole 810 along the preset direction and hooked, without the need of adjusting the angle or offsetting the deviation. When the connecting seat 800 is in the storage position, the extension direction of the connecting hole 810 is perpendicular to the preset direction, and the connecting seat 800 as a whole can be folded or attached to the surface of the first component 100 through the pivoting action, greatly reducing the occupation of the surrounding space.
