[0038] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention and are not intended to limit the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0039] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0040] Embodiment 1

[0041] Please refer to Figure 1 the first structural schematic diagram of a ventilation connector for fixing a fan provided in this embodiment shown in

[0042] The ventilation connector body 1, the ventilation connector body 1 includes: a mutually cooperating first connection part 2 and a first clamping part 3; the first connection part 2 has a first axis, and the first clamping part 3 has a second axis; the first axis and the second axis are arranged in a staggered manner in the first direction;

[0043] The first connection part 2 is used to connect with the fan 4, and the first clamping part 3 is used to connect with the automotive seat structure to complete the fixation of the fan 4 to the automotive seat structure.

[0044] In order to solve the problem that when the fan 4 is connected to the automotive seat structure, the positions of the fan connection hole 41 and the mounting hole 51 on the automotive seat structure are different (see Figure 11In the shown situation), the adapter structure is frequently used to achieve the eccentric connection between the fan 4 and the vehicle seat structure. In this way, it will cause the problem of time-consuming and laborious in the assembly process. In the embodiment of the present application, the first connection portion 2 and the first clamping portion 3 which are arranged offset in the first direction in the ventilation connector body 1 can be used to conveniently and quickly complete the eccentric connection between the fan 4 and the vehicle seat structure.

[0045] Specifically, in combination with Figure 3 、 Figure 4 、 Figure 6 、 Figure 13 and Figure 14 it can be known that the ventilation connector body 1 is a component for realizing the eccentric / misaligned connection between the fan 4 and the vehicle seat structure. The first axis and the second axis of the first connection portion 2 and the first clamping portion 3 in the ventilation connector body 1 are arranged offset in the installation direction of the fan 4 and the vehicle seat structure, that is, the first connection portion 2 and the first clamping portion 3 are eccentrically arranged. The offset distance between the two axes is not specifically limited. When the positions of the fan connection hole 41 and the installation hole 51 are different and cannot be directly connected, the eccentric design of the first connection portion 2 and the first clamping portion 3 can well overcome this problem and realize the rapid fixation of the fan 4 and the vehicle seat structure.

[0046] Regarding the "first direction", it can also be understood as the "installation direction of the fan 4 and the vehicle seat structure" or can further refer to the vertical direction in Figure 4 . Because the ventilation connector body 1 is used to solve the misaligned connection between the two, the first connection portion 2 and the first clamping portion 3 naturally need to be eccentric along the direction in which they need to be installed to complete the corresponding assembly operation. This structure can not only stably and reliably install the fan 4 on the vehicle seat structure, but also realize the commonality of most products.

[0047] It should be explained that the offset distance between the first axis and the second axis corresponding to the first connection portion 2 and the first clamping portion 3 can be designed according to the actual situation, and the specific distance is not specifically limited.

[0048] In a preferred embodiment, referring to Figure 2 and Figure 5 , the first connection portion 2 and the first clamping portion 3 are integrally formed structures.

[0049] Among them, the first connection portion 2 and the first clamping portion 3 can be an integral elastic structure. For example, materials such as rubber or silicone are used. Such material selection can facilitate the fixation and force of the ventilation connector body 1. Of course, it can also be a combination form of a rigid structure and a flexible structure; specifically, referring to Figure 1Alternatively, the ventilation connector body 1 shown in Fig. 2 is an integral elastic structure. The design of the elastic structure can further absorb the position offset between the fan connection hole 41 and the mounting hole 51 through its own elastic characteristics; see Figure 5 The ventilation connector body 1 shown is a combination of a rigid structure and a flexible structure.

[0050] In a preferred embodiment, see Figure 2 , a first groove 21 is formed in the first connecting portion 2 along its circumferential direction, and the first groove 21 is used for engaging with the fan 4.

[0051] The first groove 21 is the position where the first connecting portion 2 engages with the fan connection hole 41 after passing through the fan connection hole 41; the first groove 21 is a groove structure formed in the first connecting portion 2 and distributed along its circumferential direction. When connecting with the fan connection hole 41, the limiting protrusions formed on both sides of the first groove 21 are exactly located on both sides of the fan connection hole 41, forming an engagement with the fan 4. Here, relying on the deformable amount of the elastic structure of the first connecting portion 2, it can be directly inserted into the fan connection hole 41.

[0052] In a preferred embodiment, see Figure 1 and Figure 2 , a second groove 31 is formed in one end of the first clamping portion 3 close to the first connecting portion 2 along its circumferential direction; the second groove 31 is used for engaging with the automotive seat structure.

[0053] For the same principle as described above, since the first clamping portion 3 needs to be connected to the automotive seat structure, a groove structure distributed along the circumferential direction of the first clamping portion 3 is also provided at one end of the first clamping portion 3 close to the first connection 2, that is, the second groove 31. The second groove 31 is shorter than the first groove 21 along the length direction of the ventilation connector body 1. This is because the automotive seat structure is often a seat frame 5, a supporting sheet metal or plastic plate, etc., and the thickness of the seat frame 5 itself is smaller than the outer shell of the fan 4. However, the actual structural design of the first groove 21 and the second groove 31 needs to be adjusted according to the actual situation; in addition, during the specific connection process, after the first clamping portion 3 passes through the mounting hole 51 on the seat frame 5, the limiting protrusions formed on both sides of the second groove 31 will be clamped on both sides of the mounting hole 51, forming a fixed connection with the seat frame 5.

[0054] In a preferred embodiment, see Figure 2 , Figures 7 - 10 , the first clamping portion 3 includes: an end clamping portion 32 and a clamping main body portion 33; the end clamping portion 32 and the clamping main body portion 33 together form the second groove 31;

[0055] One side of the end clamping portion 32 is connected to the clamping main body portion 33, and the other side is connected to the first connecting portion 2.

[0056] Specifically, the first clamping part 3 includes an end clamping part 32 and a clamping main body part 33. Among them, the second axis of the first clamping part 3 is determined according to the clamping main body part 33, and the end clamping part 32 is equivalent to a misaligned connecting part shared by the first clamping part 3 and the first connecting part 2. The clamping main body part 33 and the first connecting part 2 are arranged on both sides of the end clamping part 32.

[0057] Combined with the above content, during the actual installation process, the clamping main body part 33 will pass through the installation hole 51 on the sheet metal or plastic part of the seat frame 5, and finally the installation hole 51 falls into the second groove 31. At this time, the end clamping part 32 and the clamping main body part 33 are respectively on both sides of the seat frame 5; while the first connecting part 2 will pass through the fan connecting hole 41, and finally the fan connecting hole 41 falls into the first groove 21. At this time, the end clamping part 32 and the second limiting part 22 are respectively on both sides of the fan connecting hole 41. In this way, the fan 4 and the seat frame 5 are separated by the end clamping part 32, which can effectively prevent abnormal noise caused by collision between the fan 4 and the seat frame 5, and reduce the vibration transmission of the fan 4 to the human body in the seat direction.

[0058] It should be noted that, referring to Figures 7 - 9 and Figure 10 for comparison, the end clamping part 32 can have different thicknesses, which is equivalent to that the height of the end clamping part 32 in the vertical direction can be different. A wider end clamping part 32 can absorb more pressure acting on the fan 4 and the automotive seat structure, while a slightly narrower end clamping part 32 can make the ventilation connecting piece body 1 have the advantage of light weight. Therefore, the design specifications of the end clamping part 32 can be adjusted according to the actual situation.

[0059] In a preferred embodiment, the axis of the clamping main body part 33 in the direction perpendicular to the end clamping part 32 forms a second axis; the direction of the clamping main body part 33 perpendicular to the end clamping part 32 is arranged parallel to the first direction.

[0060] When the first clamping part 3 includes an end clamping part 32 and a clamping main body part 33, the axis of the clamping main body part 33 in the direction perpendicular to the end clamping part 32 is the second axis. Then, combined with the above description, it can be known that the eccentric / misaligned setting at this time is based on the relative distribution positions of the first connecting part 2 and the clamping main body part 33. During the actual design process, the misaligned settings of the two on both sides of the end clamping part 32 are various. For specific examples, reference can be made to Figure 7 、 Figure 9 for the various structures shown.

[0061] It should be noted that the axis of the clamping main body 33 in the direction perpendicular to the end clamping part 32 is defined as the second axis here. However, in actual processing, process errors also need to be considered. In other words, a certain included angle (within ±15 degrees) between the second axis and the end clamping part 32 does not affect the use effect of the embodiment of the present application. Correspondingly, there may also be a certain angular deviation (within ±15 degrees) between the direction perpendicular to the end clamping part 32 of the clamping main body 33 and the first direction, and it is not strictly set parallel.

[0062] In a preferred embodiment, the clamping main body 33 further includes at least one first limiting part 34, and the first limiting part 34 is a convex structure, an aircraft clip or an inverted thorn structure.

[0063] See Figure 1 and Figure 2 , here the first limiting part 34 is a convex structure, and the first limiting part 34 is used to form the edge structure of the second groove 31 away from the first connecting part 2. The transverse cross-sectional length of the first limiting part 34 gradually increases along the direction of the clamping main body 33 approaching the end clamping part 32.

[0064] The design of the first limiting part 34 is first based on the generation of the second groove 31. The first limiting part 34 is equivalent to a convex structure on the clamping main body 33. At this time, a second groove 31 distributed circumferentially along the end of the clamping main body 33 can be formed between the convex structure and the end clamping part 32.

[0065] At the same time, the transverse cross-sectional length of the first limiting part 34 gradually increases along the direction of the clamping main body 33 approaching the end clamping part 32, which means that when the first clamping part 3 is clamped with the mounting hole 51, the first convex part 34 will more easily pass through the mounting hole 51, and it is more labor-saving during assembly.

[0066] It should be noted that the structure of the first limiting part 34 is not limited to the illustrated structure. Existing aircraft clips or inverted thorn structures can also achieve the limiting effect, and at the same time, the connection strength between the first clamping part 3 and the vehicle seat structure can be further enhanced. Therefore, the design form and quantity of the first limiting part 34 can be adjusted according to actual situations. For example Figure 2 as shown, two first limiting parts 34 are arranged at intervals. Regarding the material of the first limiting part 34, when the first limiting part 34 is an aircraft clip or an inverted thorn structure, preferably, the first limiting part 34 is made of flexible rubber or silica gel material, or can also be a hard plastic material, a material with a certain deformation amount, which is more conducive to installation.

[0067] In addition, the first connecting part 2 further includes at least one second limiting part 22, and the second limiting part 22 is a convex structure, an aircraft clip or an inverted thorn structure.

[0068] The second limiting portion 22 can cooperate with the end clamping portion 32 to form the edge structures on both sides of the first groove 21; preferably, the transverse cross-sectional length of the second limiting portion 22 gradually increases in the direction close to the end clamping portion 32.

[0069] For the same principle as described above, refer to Figure 1 , there are two second limiting portions 22 provided on the first connecting portion 2. The second limiting portions 22 are equivalent to the protruding structures on the first connecting portion 2. Based on these two protruding structures, the first groove 21 on the first connecting portion 2 is formed. The first groove 21 is used for clamping with the fan connection hole 41. For the convenience and labor-saving of clamping, the transverse cross-sectional length of the second limiting portion 22 is designed to gradually increase in the direction close to the end clamping portion 32. In this way, it will be more labor-saving when the first connecting portion 2 is inserted into the fan connection hole 41 vertically from top to bottom. Similarly, in addition to the structure shown in the figure, the second limiting portion 22 can also adopt an aircraft clip or an inverted thorn structure, and the specific description will not be elaborated here.

[0070] In a preferred embodiment, refer to Figure 5 , there is a clamping groove 35 provided on the first clamping portion 3; the first clamping portion 3 is clamped with the vehicle seat structure through the clamping groove 35;

[0071] The opening of the clamping groove 35 is arranged in the second direction, and the second direction is perpendicular to the extending direction of the second axis; a plurality of clamping segments 36 are arranged in the clamping groove 35, and the clamping segments 36 are used to assist in fixing the clamping groove 35 with the vehicle seat structure.

[0072] As Figure 6 shown, in order to ensure the connection stability, here the first clamping portion 3 can be selected in the structural form with a sheet metal clamping seat, so that it has a certain clamping force. Therefore, at this time, the ventilation connector body 1 can adopt a split structure based on different materials, that is, the combination of the sheet metal clamping seat and the first connecting portion 2 and the first clamping portion 3 made of rubber or silicone materials. In such a design, since the ventilation connector body 1 is a split structure with different materials, when in use, the structural carrier of the clamping groove 35 needs to be installed on the clamping main body portion 33.

[0073] It should be explained that the second direction defined here is the horizontal direction, and the opening direction of the clamping groove 35 and the extending direction of the second axis are not strictly perpendicular. Similarly, considering the process error, the specific deviation within ±10 degrees will not affect the use effect of the embodiments of the present application.

[0074] In addition, as Figure 5 , Figure 6 , Figure 13 and Figure 14As shown, the engaging groove 35 formed by the first engaging portion 3 is the portion where the first engaging portion 3 is engaged with the car seat structure. At the same time, a plurality of engaging sections 36 are also arranged in the engaging groove 35. Taking the car seat structure as a seat frame 5 as an example, the thickness of the seat frame 5 needs to match the engaging groove 35 along the vertical direction to ensure that the seat frame 5 can be clamped when it is extended into the engaging groove 35. At the same time, an engaging section 36 is also arranged in the engaging groove 35. Under the split structure, the engaging section 36 is generally made of metal to provide a greater clamping force and improve the connection strength between the fan 4 and the seat frame 5.

[0075] It needs to be explained that if the first clamping portion 3 is in the form of a sheet metal socket, a layer of flexible pad 8 can be added to the surface of the fan 4 close to the internal structure of the seat. In this way, the first clamping portion 3 formed by the sheet metal socket will not directly contact the upper surface of the fan 4 after assembly, thereby avoiding scratches and wear between the two.

[0076] Example 2

[0077] See also Figure 4 , based on a ventilation connector for fixing a fan in Embodiment 1, the embodiment of the present application proposes a car seat comprising: a car seat structure and a fan 4 arranged on the car seat structure;

[0078] The automobile seat structure includes: a seat frame 5 and a foam 6 arranged on the seat frame 5; a ventilation component 7 is arranged between the seat frame 5 and the foam 6; the seat frame 5 is connected to the fan 4 through the ventilation connector body 1 to achieve air circulation between the ventilation component 7 and the surface of the foam 6.

[0079] During the assembly process of the fan 4 and the automobile seat structure, it is found that the mounting hole 51 on the seat frame 5 and the fan connection hole 41 on the fan 4 are located at different positions (see Figure 11 ), when the holes cannot be matched, the connection can be made through the ventilation connector body 1. Since the first connecting portion 2 and the first clamping portion 3 of the ventilation connector body 1 are eccentrically arranged, they can well adapt to the misalignment of the mounting hole 51 and the fan connecting hole 41, which greatly overcomes the time-consuming and labor-intensive problem caused by using a switching structure to achieve an eccentric connection between the fan 4 and the seat frame 5.

[0080] In addition, based on the use of the ventilation connector body 1, the fan 4 and the seat frame 5 can be separated by the end clamping portion 32 of the ventilation connector body 1 after the connection is completed, thereby effectively preventing abnormal noise caused by collision between the fan 4 and the seat frame 5, and reducing the transmission of vibration generated by the fan 4 to the human body in the direction of the seat.

[0081] After the fan 4 and the seat frame 5 are installed, the fan 4 can be connected to the foam 6 through the ventilation member 7 to achieve the connection of the air path, so as to ensure that the fan 4 can suck air or blow air to the surface of the car seat, providing a comfortable seating environment for the user sitting on the car seat.

[0082] The above description is only the preferred embodiment of the present application and the description of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
