[0025] It should be noted that in the description of the present application, the meaning of "and / or" is to include three parallel solutions, for example, "A and / or B" includes A solution, or B solution, or A and B solution.

[0026] The following refers to Figures 1-12 The joint assembly 20, the ventilation system 1000 and the seat 10000 according to the embodiments of the present application are described.

[0027] The joint assembly 20 can be used in the ventilation system 1000 with the ventilation pipe 10. The application scenarios of the ventilation system 1000 are very wide, which can be used in many types of equipment that need to connect air ducts or guide air flow. Exemplary application scenarios include but are not limited to: air conditioner indoor unit or outdoor unit, household or industrial fan, air purifier, fresh air system, warm air machine, dehumidifier, exhaust device, and other air handling equipment with air ducts or connected with air ducts.

[0028] As Figures 1-3 shown, the joint assembly 20 according to the first aspect of the present application comprises: an adapter pipe 21 and a secondary door bolt 23. The two ends of the adapter pipe 21 are pipe one end 2-a and pipe two end 2-b respectively, the adapter pipe 21 is used for connecting the ventilation pipe 10 at the pipe one end 2-a, and the adapter pipe 21 is used for connecting a component interface at the pipe one end 2-a. The specific component is not limited. The inner wall of the adapter pipe 21 is provided with a clamping part 215, and the clamping part 215 is used for clamping a device inserted into the interface of the pipe two end 2-b.

[0029] The inner wall of the adapter pipe 21 is provided with a plurality of locking members 22. One end of the locking member 22 is arranged on the inner wall of the adapter pipe 21, and the other end of the locking member 22 is arranged towards the pipe one end 2-a of the adapter pipe 21.

[0030] The function of the locking member 22 is to lock and fix the ventilation pipe 10 in the adapter pipe 21, so as to prevent it from loosening under the action of air flow or vibration, and therefore it is defined as the locking member 22.

[0031] Specifically, one end of each locking member 22 is arranged on the inner wall of the adapter pipe 21, and the other end is a free end. These locking members 22 can be elastically deformed inside the adapter pipe 21 to facilitate the locking or releasing function.

[0032] The joint assembly 20 is arranged at at least one end of the ventilation pipe 10, and the end of the ventilation pipe 10 is detachably inserted into the gap between the adapter pipe 21 and the locking member 22.

[0033] In this embodiment, when the secondary door bolt 23 is inserted into the adapter pipe 21, the free end of the locking member 22 is pushed to rotate, thereby completing the locking action.

[0034] The secondary door bolt 23 is tubular, and the secondary door bolt 23 is inserted into the adapter pipe 21 from the pipe end 2-b of the adapter pipe 21 and holds the locking member 22 to rotate, so that the end of the locking member 22 is clamped to the inner wall of the ventilation pipe 10. That is, the secondary door bolt 23 is pressed against the inner side of the locking member 22 to make the locking member 22 rotate and be clamped to the inner wall of the ventilation pipe 10.

[0035] Here, the shape and size of the secondary door bolt 23 are adapted to the inner profile of the locking member 22, so that when the secondary door bolt 23 is inserted into the adapter pipe 21 and pressed against the inner side of the locking member 22, a uniform radial pressure can be applied to the locking member 22, prompting the locking member 22 to rotate outward around its connection end with the adapter pipe 21, so that the outer side of the locking member 22 is reliably abutted and clamped to the inner wall of the ventilation pipe 10, achieving stable mechanical locking.

[0036] Such a locking mode does not need to rely on the setting of bosses, grooves or other special structures on the end of the ventilation pipe 10, reduces the requirements for the machining precision and structural form of the ventilation pipe 10, and realizes the adaptability of the joint assembly to different types or specifications of ventilation pipes 10.

[0037] Since the locking action is automatically triggered and pressed when the secondary door bolt 23 is inserted into the adapter pipe 21, the operator only needs to perform the plugging operation to achieve locking.

[0038] Moreover, no additional tools are needed in the process of connecting the ventilation pipe 10, improving the installation convenience.

[0039] At the same time, this locking mode can effectively resist the impact of airflow and equipment vibration during equipment operation, preventing the ventilation pipe 10 from loosening or air leakage, thereby improving the sealing performance and operation stability of the system.

[0040] Optionally, the secondary door bolt 23 can be inserted into the adapter pipe 21 by axial sliding, rotating and pushing or screwing, etc.

[0041] In some technical solutions, the outer side of the locking member 22 is provided with an anti-slip structure for increasing the friction with the inner wall of the ventilation pipe 10. Specifically, the anti-slip structure can include protrusions, teeth, rubber pads or anti-slip coatings, etc. to enhance the friction.

[0042] In some alternative embodiments, an annular sealing ring can be arranged between the ventilation pipe 10 and the adapter pipe 21 to further improve the air tightness of the connection and prevent air leakage.

[0043] The joint assembly 20 can be arranged at one end or both ends of the ventilation pipe 10. This arrangement can improve the adaptability to different connection scenarios.

[0044] In summary, by arranging the joint assembly 20 including the adapter pipe 21, the rotatable locking member 22, and the tubular secondary door bolt 23, and arranging the joint assembly 20 at the end of the ventilation pipe 10, the end of the ventilation pipe 10 is inserted into the adapter pipe 21, and the secondary door bolt 23 is pressed against the inner side of the locking member 22, which causes the outer side of the locking member 22 to tightly clamp the inner wall of the ventilation pipe 10, thereby achieving reliable mechanical locking without the need for external protrusions or special structures of the ventilation pipe 10. This joint assembly 20 not only simplifies the processing requirements of the ventilation pipe 10, improves the assembly convenience and connection stability, but also effectively resists vibration and airflow impact during equipment operation, prevents loosening and air leakage, and enhances the adaptability and flexibility of the ventilation system.

[0045] Optionally, the clamping part 215 can be a clamping protrusion or a clamping hole. The adapter pipe 21 is used to connect a component interface at one end 2-a of the pipe, and the component interface is provided with a corresponding clamping structure, for example, as shown in Figure 1 The adapter interface 201 of the fan 200 is used to connect the one end 2-a of the pipe of the adapter pipe 21, and the adapter interface 201 of the fan 200 is provided with a clamping ring 202 clamped on the clamping part 215.

[0046] As shown in Figure 4 In some embodiments, the adapter pipe 21 includes a first pipe segment 211, a wire plate 214, a second pipe segment 212, and a limiting protruding ring 213. The limiting protruding ring 213 is connected between the first pipe segment 211 and the second pipe segment 212.

[0047] Specifically, the first pipe segment 211, the limiting protruding ring 213, and the second pipe segment 212 are connected in sequence. The end of the first pipe segment 211 constitutes the one end 2-a of the pipe, the end of the second pipe segment 212 constitutes the two end 2-b of the pipe, and the clamping part 215 is arranged on the inner wall of the second pipe segment 212.

[0048] The first pipe segment 211 and the wire plate 214 form a groove 211-1, and the end of the ventilation pipe 10 is inserted and held in the groove 211-1.

[0049] In this way, the end of the ventilation pipe 10 can be stably embedded in the groove 211-1, improving the stability of the connection.

[0050] The second pipe segment 212 is connected to the first pipe segment 211 on the side away from the ventilation pipe 10. The end of the ventilation pipe 10 abuts against the limiting convex ring 213. One end of the locking member 22 is connected to the limiting convex ring 213. The secondary door bolt 23 is inserted into the first pipe segment 211 from the second pipe segment 212 and abuts against the limiting convex ring 213.

[0051] Here, the limiting convex ring 213 functions to limit the insertion depth of the ventilation pipe 10, ensuring that the end thereof abuts against the same position each time the assembly is performed, so that the locking member 22 can stably and reliably act on the predetermined region of the inner wall of the ventilation pipe 10, effectively preventing locking failure caused by insufficient or excessive insertion.

[0052] The limiting convex ring 213 simultaneously serves as a mounting base of the locking member 22, providing a stable connection point for the locking member 22, so that the locking member 22 can effectively turn outward and tightly abut against the inner wall of the ventilation pipe 10 when subjected to the pressure applied by the secondary door bolt 23, achieving reliable mechanical locking.

[0053] The secondary door bolt 23 is inserted into the second pipe segment 212 and abuts against the limiting convex ring 213, thereby effectively limiting the axial position thereof, preventing locking failure possibly caused by excessive insertion of the secondary door bolt 23, and further ensuring the stability of the connection and the reliability of the sealing.

[0054] Optionally, the first pipe segment 211, the second pipe segment 212, and the limiting convex ring 213 can be formed by one-time processing. For example, the first pipe segment 211, the second pipe segment 212, and the limiting convex ring 213 can be integrally injection molded. Of course, the present application is not limited thereto, and the limiting convex ring 213 can be processed on the basis of one-time processing of the first pipe segment 211 and the second pipe segment 212, such as by machining, grinding, or other processing procedures.

[0055] Further, the adapter pipe 21 further comprises a wire plate 214, which is located in the first pipe segment 211 and connected to the limiting convex ring 213. The wire plate 214 is multiple and arranged at intervals along the limiting convex ring 213, and the inner wall surface of the ventilation pipe 10 is in contact with the wire plate 214.

[0056] In the above technical solution, the multiple circumferentially spaced wire plates 214 can function to center and guide the inserted ventilation pipe 10 in the radial direction, ensuring that the ventilation pipe 10 maintains coaxiality during the insertion process, and avoiding uneven force or ineffective clamping of the locking member 22 caused by deflection.

[0057] Meanwhile, the wire plate 214 can adapt to different specifications or cross-sectional shapes of the ventilation pipe 10 for centering and guiding, that is, even if the ventilation pipe 10 has a certain tolerance in the inner diameter size or roundness, the wire plate 214 arranged in the circumferential direction can be in point and / or line contact with the inner wall of the ventilation pipe 10 to realize automatic centering, so as to ensure that the locking member 22 always acts on the effective position, maintain the reliability of the connection, improve the compatibility of the joint assembly for various specifications of the ventilation pipe, and enhance the versatility and flexibility of the ventilation system 1000.

[0058] In addition, the contact between the wire plate 214 and the inner wall of the ventilation pipe 10 can limit the slight rotation or shaking of the ventilation pipe 10 in the radial direction, improve the stability of the connection, and especially when the equipment is running, it helps to maintain the stability of the interface.

[0059] Optionally, the wire plate 214 can include a cantilever beam or an arc-shaped elastic sheet with elasticity. In this way, the elasticity of the material automatically adapts to ventilation pipes of different inner diameters, improving the adaptability to the ventilation pipe 10.

[0060] Further optionally, a tapered slope is arranged on the inner wall of the first pipe section 211 to guide the automatic centering of the ventilation pipe 10 and improve the installation convenience.

[0061] In some technical solutions, the wire plate 214 can be multiple and uniformly or non-uniformly distributed in the circumferential direction.

[0062] As shown in Figure 6 and Figure 7 , the wire plate 214 is arranged to extend obliquely away from the limiting convex ring 213 and towards the axis L of the adapter pipe 21.

[0063] In this way, the wire plate 214 forms a converging guide structure. The oblique arrangement allows the inner wall of the ventilation pipe 10 to contact the inclined surface of the wire plate 214 and be guided radially during the insertion process, so as to automatically adjust the position and center on the central axis of the adapter pipe 21, improving the smoothness of the insertion and the assembly efficiency.

[0064] According to some optional embodiments of the present application, the locking member 22 is integrally formed on the adapter pipe 21.

[0065] For example, the locking member 22 and the adapter pipe 21 are integrally injection molded. The integrally injection molded part does not require additional assembly or connection process, improves production efficiency, and reduces production cost. At the same time, it avoids the possible connection looseness and improves the structural stability of the ventilation system 1000.

[0066] The end of the locking member 22 connected to the adapter pipe 21 is a thin rod, so that the locking member 22 can rotate.

[0067] Specifically, the cross-sectional dimension of the connecting portion of the adapter pipe 21 is significantly smaller than that of the main body portion of the locking member 22, so as to ensure the structural continuity and impart sufficient torsional or bending flexibility.

[0068] Such a structure is conducive to forming a flexible connection portion, so that the locking member 20 can rotate or elastically swing relative to the adapter pipe 21.

[0069] Further, the locking member 22 comprises a connecting strip 225 and a clamping protrusion 226. One end of the connecting strip 225 is connected to the adapter pipe 21. The clamping protrusion 226 is located at the other end of the connecting strip 225 and is connected to the side of the connecting strip 225 facing the outer wall surface of the adapter pipe 21. In the natural state, the connecting strip 225 is inclinedly arranged towards the axis L of the adapter pipe 21 from the end connected to the adapter pipe 21 to the clamping protrusion 226. The secondary door bolt 23 is inserted from the end connected to the adapter pipe 21.

[0070] In combination Figure 5 and Figure 6 , after the ventilation pipe 10 is inserted into the adapter pipe 21, the secondary door bolt 23 is inserted into the end of the adapter pipe 21 and pushed axially, and the inner wall of the secondary door bolt 23 acts on the inner side of the connecting strip 225 to exert an outward pushing force on the connecting strip 225. Under the action, the connecting strip 225 elastically deforms or rotates about the connecting portion as the fulcrum, driving the clamping protrusion 226 to swing outward, so as to abut against the inner wall of the ventilation pipe 10, thereby achieving reliable mechanical locking. Such an arrangement improves the locking efficiency and contact pressure and enhances the anti-disengagement performance.

[0071] In some alternative technical solutions, as shown in Figure 5 , a plurality of guide ribs 231 are arranged on the outer wall surface of the secondary door bolt 23 and extend along the direction of the axis L of the adapter pipe 21.

[0072] A guide groove 232 is formed between two guide ribs 231 in a group, and the locking member 22 is clamped in the guide groove 232.

[0073] The guide ribs 231 cooperate with the locking member 22 to guide the locking member 22 to rotate towards the outer peripheral wall of the adapter pipe 21 during the insertion of the secondary door bolt 23, so as to avoid the situation that the locking member 22 is skewed or broken due to contact with the secondary door bolt 23 during the insertion of the secondary door bolt 23. Thus, not only the smoothness and positioning accuracy of the operation of the secondary door bolt 23 are improved, but also the locking failure caused by skewing or jamming is avoided, which is conducive to maintaining the locking accuracy and uniform stress of the locking member 22 and improving the reliability and service life of the overall connection.

[0074] The ventilation pipe 10 comprises a guide inner pipe 11 and a spring 12. The inner wall surface of the guide inner pipe 11 is smooth. The spring 12 is arranged on the guide inner pipe 11, and the locking piece 22 is clamped on the spring 12 after extruding the guide inner pipe 11.

[0075] The smooth inner wall surface of the guide inner pipe 11 helps to reduce air flow resistance, reduce wind noise, and improve ventilation efficiency.

[0076] The guide inner pipe 11 is a plastic material piece and has a deformable characteristic. When the clamping protrusion 226 of the locking piece 22 extrudes outward, the guide inner pipe 11 locally elastically deforms, so that the clamping protrusion 226 is clamped on the spring 12 after extruding the guide inner pipe 11, and reliable locking is achieved.

[0077] Meanwhile, the spring 12 also has a certain locking reaction force, which not only improves the vibration resistance and durability of the connection, but also protects the guide inner pipe 11 from continuous stress damage and prolongs the service life of the ventilation pipe 10.

[0078] According to the ventilation system 1000 of the second aspect of the present application, the ventilation system 1000 comprises a fan 200, a ventilation pipe 10 and a joint assembly 20. The fan 200 has a rotating interface 201. The joint assembly 20 is the joint assembly 20 in the first aspect of the present application. The joint assembly 20 is connected between the rotating interface 201 of the fan 200 and the ventilation pipe 10.

[0079] By adopting the improved joint assembly 20, the ventilation system 1000 can realize quick and reliable connection between the ventilation pipe 10 and the fan 200, without relying on the special structure of the end of the ventilation pipe 10, reducing the assembly difficulty and manufacturing cost. At the same time, the locking structure in the ventilation system 1000 can effectively resist the vibration and air flow impact during operation, prevent loosening, and thus improve the operation stability of the whole machine.

[0080] According to the vehicle of the third aspect of the present application, the ventilation system 1000 of the above-mentioned embodiments can be provided. The ventilation system 1000 can be provided in the air conditioning device of the vehicle, or can be provided in other positions requiring ventilation.

[0081] For example, as shown in Figure 8 The seat 10000 comprises a backrest 2000, a seat cushion 3000 and a ventilation system 1000. The back surface of the backrest 2000 is provided with a backrest air bag interface 2001. The back surface of the seat cushion 3000 is provided with a seat cushion air bag interface 3001. The ventilation system 1000 is the ventilation system 1000 of the above-mentioned embodiments. Among them, the fan 200 is connected to one of the backrest air bag interface 2001 and the seat cushion air bag interface 3001, and the end of the ventilation pipe 10 away from the fan 200 is connected to the other one of the backrest air bag interface 2001 and the seat cushion air bag interface 3001.

[0082] Specifically, the ventilation system 1000 is provided with a joint assembly 20 at each end of the ventilation pipe 10. The ventilation pipe 10 is connected to the adapter interface 201 of the fan 200 at one end through a joint assembly 20. The ventilation pipe 10 is connected to a wind bag 400 at the other end through another joint assembly 20. Here, the wind bag 400 can be connected to the backrest 2000 or the backrest 2000. The wind bag 400 is provided with a wind bag interface 410, which is one of the backrest wind bag interface 2001 and the seat cushion wind bag interface 3001.
