Description

Technical Field

[0001] This disclosure specifically discloses a fan connection element; a fan connection structure using the fan connection element; and an automotive seat using the fan connection structure. Background Technology

[0002] To improve ride comfort, existing car seats are usually equipped with active ventilation structures to provide a continuous airflow from the direction of the car seat to the occupant during hot seasons, carrying away the heat generated by the contact area between the occupant and the car seat, thereby improving the overall comfort of the car seat.

[0003] However, in existing car seat structures, the seat frame at the bottom of the seat cushion or on the backrest has various curved shapes, such as: seat springs made of steel wires with different shapes; seat suspension plates made of a single sheet of metal with multiple mounting holes; seat suspension plates made of a single sheet of plastic with multiple mounting holes; and seat springs made of steel wires with different shapes and plastic parts partially wrapped around the steel wires. Given these diverse seat frame structures, it is difficult to have standardized mounting components or methods in existing fan mounting structures, especially in newly developed product structures. Often, it is necessary to create new molds to manufacture the corresponding fan connecting elements and mounting structures. Over time, this not only reduces production efficiency but also increases production costs.

[0004] In existing technologies, fan adapter mounting brackets are often used for fan mounting. First, the fan is fixed to the adapter mounting bracket, and then the adapter mounting bracket is fixed to the receiving bracket, thus achieving a preliminary unified installation method. However, this also brings new problems. On the one hand, the adaptability of the adapter mounting bracket cannot cover most product categories; on the other hand, the adapter mounting bracket increases the space occupied by the fan mounting location, which is not conducive to the integrated design of car seats, and urgently needs improvement.

[0014] This technical solution specifically discloses a specific structure for a fan connecting element. In this technical solution, the fan body connecting part is used to connect with the fan body; the frame connecting part is used to fix to the rod-shaped component or the hole-shaped part. Specifically, the rod-shaped component or the hole-shaped part corresponds to different structures of the seat frame, wherein: the rod-shaped component corresponds to the seat suspension spring made of steel wire; the hole-shaped part corresponds to the mounting holes provided on the whole piece of plastic material or metal sheet. Based on the above design, this technical solution can quickly and conveniently realize the connection between the fan and the seat frame.

In specific use, after selecting the mating angle between the two, the fan body connecting part and the transfer connecting part are fixedly connected. On the other hand, the frame connecting part can move along the length direction of the transfer connecting plate. During the mating process, when the frame connecting part is moved along the length direction of the transfer connecting plate to the preset installation position, the transfer connecting plate and the frame connecting part are fixedly connected to achieve installation between the frame connecting part and the transfer connecting plate.

[0046] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Please refer to Figure 1a One embodiment of a fan connection element 100 is shown.

[0049] The fan connecting element includes: a fan body connecting part 101 and a frame connecting part 102; the fan body connecting part 101 is provided with a first clip 103 that can be fixedly connected to the fan; the frame connecting part 102 may be provided with a second clip 104 that can be fixedly connected to a rod-shaped component; or a third clip 105 that can be fixedly connected to a hole-shaped part.

[0050] in:

[0051] The fan body connecting part 101 is used to connect to the fan; in order to facilitate the connection with the fan, the fan body connecting part 101 is provided with a first clip 103 that can be fixedly connected to the fan.

[0052] The frame connecting part 102 is used to fix to the rod-shaped component or the hole-shaped part on the seat frame 300. When the seat frame 300 is a seat suspension spring made of steel wire, the steel wire has a rod-shaped structure, and the frame connecting part 102 has a second locking member 104 that can be fixed to the rod-shaped component. When the seat frame 300 is made of a single piece of plastic material or a single piece of metal sheet and has mounting holes, the frame connecting part 102 has a third locking member 105 that can be locked or inserted into the hole-shaped part.

[0053] Figure 1a 101 points to the fan body connection part, and 102 points to the frame connection part, which are located at both ends. Among them, 101 is connected to the fan body and 102 is connected to the seat frame 300.

[0054] Specifically, the fan body is designed with a fixed mounting point, and the first clip 103 on the fan body connecting part 101 and the fixed mounting point of the fan are fixedly connected by means of overlapping, snapping, welding, bonding, etc.

[0055] Specifically, when the seat frame 300 is a seat suspension spring made of steel wire, the steel wire has a rod-shaped structure. The second clip on the frame connecting part 102 is connected to the seat frame 300 by snapping, plugging, or hanging, forming a fixed connection relationship.

[0056] When the seat frame 300 is made of a single piece of plastic material or a single piece of metal sheet and has mounting holes, the third clip on the frame connecting part 102 is connected to the seat frame 300 by snap-fit, plug-in, or hook-fit, forming a fixed connection relationship.

[0057] Optionally, the number of the first card, the second card, and the third card may be one or more.

[0058] Specifically, the specific structures of the first, second, and third clips are not limited here, as long as they can form a fixed connection with the fan body or the seat frame.

[0059] Please refer to Figure 1b This illustration shows one embodiment of a fan connecting element 100. The dimensions of the portions welded or bonded together between the fan body connecting portion 101 and the frame connecting portion 102 may not be exactly the same. Furthermore, when the two are fixed together, their centers may be offset from each other.

[0060] Based on the above design, this specific embodiment can quickly and conveniently connect the fan to the seat frame. Compared with the existing technology that uses an adapter frame, this technical solution replaces the sheet-like or block-like adapter frame with a fan fixing device, realizing point-like installation instead of sheet-like installation. This allows for stable and reliable installation of the fan body using the first clip, or the seat frame using the second or third clip; at the same time, it does not limit the specific structure of the first, second, or third clip, enabling installation structures adaptable to most product categories. More importantly, the single-point installation structure itself does not occupy a large space.

[0061] Please refer to Figure 2a This illustrates one embodiment of a fan connection element.

[0062] The fan body connecting part 101 and the frame connecting part 102 are rotatably connected; and the fan body connecting part 101 can be fixedly connected to the frame connecting part 102 at a selectable angle.

[0063] In specific production scenarios, the fan body connecting part and the frame connecting part are manufactured separately.

[0064] Figure 2a In the diagram, the arrow indicates that the fan-shaped connecting part and the frame connecting part can rotate relative to each other. During the connection process, the two parts are designed to be rotatable.

[0065] In practical use, after selecting the mating angle between the two, the fan body connecting part is fixedly connected to the frame connecting part.

[0066] Please refer to Figure 2b and Figure 2c This illustrates one embodiment of a fan connection element.

[0067] The frame connecting part 102 can move along the length direction of the fan body connecting part 101; and the frame connecting part 102 can be selectively fixed to the fan body connecting part 101.

[0068] The frame connecting part of this technical solution is designed to be movable along the length direction of the fan body connecting part. Optionally, the base plate of the fan body connecting part has a rectangular structure.

[0069] Figure 2b In the diagram, the dashed lines represent state one, and the solid lines represent state two. Based on... Figure 2b In the design, the fan body connecting part can move relative to the frame connecting part, and this is achieved by making the frame connecting part move along the length direction of the fan body connecting part.

[0070] Based on this design, during the assembly process, when the frame connecting part is moved along the length of the fan body connecting part to the preset installation position, the fan body connecting part and the frame connecting part are fixed together, so as to achieve staggered installation between the frame connecting part and the fan body connecting part. Please refer to [reference needed]. Figure 2c The final installation state is shown.

[0071] Alternatively, please refer to Figure 2c The fan body connecting part 101 has a first track groove 1011 extending along its length direction on the side opposite to the frame connecting part 102, and the frame connecting part

[0072] 102 can move along the length of the first track groove 1011.

[0073] Please refer to Figure 3a and 3b This illustrates one embodiment of a fan connection element.

[0074] It also includes: transfer connecting plate 106. Based on the design of the transfer connecting plate, the connection mode between the frame connecting part and the fan body connecting part can be more diverse.

[0075] On one hand, the fan body connecting part can rotate relative to the transfer connecting plate. In specific use, after selecting the mating angle between the two, the fan body connecting part and the transfer connecting part are fixedly connected. That is, the first side of the transfer connecting plate 106 is rotatably connected to the fan body connecting part 101; and the fan body connecting part 101 is fixedly connected to the transfer connecting plate 106 at a selectable angle. Figure 3a As shown, Figure 3a The direction indicated by the rotating arrow shows that the transfer connecting plate can be in different positions. At the same time, the frame connecting part installed with the transfer connecting plate can also have different relative mating angles with the fan body connecting part, so that the connecting element can adapt to more application scenarios.

[0076] On the other hand, the frame connecting part can move along the length direction of the transfer connecting plate. During the mating process, when the frame connecting part is moved along the length direction of the transfer connecting plate to a preset installation position, the transfer connecting plate and the frame connecting part are fixedly connected, so that the frame connecting part and the transfer connecting plate can be installed. That is, the second side of the transfer connecting plate 106 is connected to the frame connecting part 102, and the frame connecting part 102 can move along the length direction of the transfer connecting plate 106; and the frame connecting part 102 can be selectively fixedly connected to the transfer connecting plate 106. Figure 3b As shown, the horizontal arrow points to the direction in which the frame connecting part can move along the length of the transfer connecting plate, so that the frame connecting part can be installed at different positions on the transfer connecting plate.

[0077] In combination with the overall design of the transfer connection plate, on the one hand, the transfer connection plate allows the fan body connection part and the frame connection part to present different relative mating angles; on the other hand, the transfer connection plate allows the relative distance between the fan body connection part and the frame connection part to be adjustable. Therefore, the design of the transfer connection plate allows the connecting element to adapt to more application scenarios and present more different usage states.

[0078] Alternatively, please refer to Figure 3c This illustrates one embodiment of a fan connection element. A second track groove 1061 extending along its length is provided on the second side of the transfer connection plate 106, and the frame connection portion 102 is movable along the length direction of the second track groove 1061. Figure 3c The diagram shows a three-dimensional structural schematic of a connecting element with a transfer connecting plate. Figure 3c The connection between the frame connecting part and the transfer connecting plate is defined in the design. The transfer connecting plate 106 has a second track groove 1061 extending along its length on its second side. Optionally, the frame connecting part has a mating block that mates with the second track groove. Specifically, the two ends of the second track groove can limit the movement position of the mating block.

[0079] Please refer to Figure 4a In one embodiment of the first locking component shown, the first locking component 103 includes: a first locking seat 1031 and two first locking claws 1032 symmetrically disposed on one side of the first locking seat 1031. The first locking seat 1031 can be rotated to any angle and then fixedly connected to the frame connecting part 102 or the transfer connecting plate 106.

[0080] In order to apply the specific implementation structure of the first clip, when the fan is provided with a fixed mounting post, specifically, the two first clips can clamp the fixed mounting point, such as the fixed mounting post, to realize the connection between the first clip and the fan, that is, the connection between the fan body connecting part and the fan.

[0081] Please refer to Figure 4b In one embodiment of the first locking component shown, the first locking component 103 includes: a second locking seat 1033, a first locking post 1034 disposed in the center of the second locking seat 1033, and a curved first locking plate 1035 surrounding the first locking post 1034. Two second locking claws 1036 are symmetrically arranged on both sides of the first locking plate 1035, and curved outer edges 1037 are symmetrically arranged on the free ends of the two second locking claws 1036 respectively. The second locking seat 1033 can be rotated to any angle and then fixedly connected to the frame connecting part 102 or the transfer connecting plate 106.

[0082] To implement the specific structure of the first clip mentioned above, when the fan is provided with a mounting ring, the hole in the center of the mounting ring is aligned with the first clip post, and the outer wall of the hole ring is inserted into the curved first clip plate, so as to fix the first clip to the fan.

[0083] Alternatively, please refer to Figure 4c Two reinforcing plates 1038 are symmetrically provided on the side walls of the two second claws 1036 that are relatively far apart.

[0084] Please refer to Figure 5a In one embodiment of the second locking component shown, the second locking component 104 includes: a third locking seat 1041, a locking post 1045 fixed to one side of the third locking seat 1041 and having a curved longitudinal section, and transition plates 1042 symmetrically disposed on both sides of the locking post 1045; one of the two transition plates 1042 has a buckle at its free end and a card that can engage with the buckle at its other free end; when the card engages with the buckle, a space is formed between the third locking seat 1041 and the two transition plates 1042 that can accommodate the rod-shaped component; the side of the third locking seat 1041 that is relatively away from the transition plate 1042 is connected to the fan body connecting part 101 or the transfer connecting plate 106.

[0085] Specifically, the locking post has a columnar structure with a slot extending along its length, giving it a curved longitudinal section. The locking post engages with the steel wire of the seat suspension spring.

[0086] Two transition plates are symmetrically provided on the two edges of the clamping column. These transition plates are used to close the free ends of the two transition plates.

[0087] The rod-shaped component is confined within the space formed between the clamping post and the two transition plates 1052 to achieve a fixed connection between the frame connecting part and the seat frame of the seat suspension structure.

[0088] Specifically, one of the two transition plates has a latch at its free end and a card at its other free end that can engage with the latch. Optionally, the card extends horizontally toward the latch.

[0089] Please refer to Figure 5b In one embodiment of the second locking component shown, the second locking component 104 includes: a fourth locking base 1043 and two L-shaped elastic hooks 1044 symmetrically disposed on the fourth locking base 1043, with the free ends of the two elastic hooks 1044 in contact with each other; a rod-shaped component can be accommodated between the two elastic hooks 1044 and a rod-shaped component that enters between them can be prevented from falling off between them; the side of the fourth locking base 1043 that is relatively far away from the elastic hooks 1044 is connected to the fan body connecting part 101 or the transfer connecting plate 106.

[0090] Optionally, the two elastic hooks are L-shaped, and the free ends of the two hooks are in contact with each other, so that a space is formed between the two elastic hooks that can accommodate the rod-shaped component.

[0091] In specific application scenarios, the rod-shaped component is pressed between two elastic hooks. After it is inserted, the free ends of the elastic hooks can return to their initial state, stably confining the rod-shaped component between the two elastic hooks to form a space that can accommodate the rod-shaped component.

[0092] Please refer to Figure 6a One embodiment of the third locking component shown is that the third locking component 105 includes: a fifth locking seat 1051, a first central support column disposed in the center of the fifth locking seat 1051, and a plurality of rings 1052 distributed along the axial direction of the first central support column that can be locked with the hole-shaped portion; a conical locking cover 1053 is provided on one end of the first central support column that is relatively close to the fan body connecting portion 101.

[0093] Optionally, the first central support column has a columnar structure with multiple ring clips on it. The ring clips enter the mounting holes on the corresponding whole piece of plastic or metal sheet to fix the third clip to the seat frame.

[0094] Optionally, the ring card has a ring structure.

[0095] Optionally, the longitudinal section of the ring card has an inverted conical structure.

[0096] Based on the above design, in specific application scenarios, the first intermediate support column and its ring clamp can be fixed to the hole-shaped part by means of the ring clamp.

[0097] Optionally, the cross-sectional structure of the first intermediate support column is elliptical to match the structure of the elliptical hole-shaped part.

[0098] Optionally, the first intermediate support column includes two separately arranged semi-column-shaped structures, and a longitudinal retaining plate of rectangular structure is provided between the two separately arranged semi-column-shaped structures.

[0099] Please refer to Figure 6b One embodiment of the third locking component shown is that the third locking component 105 includes: a fifth locking seat 1051 and a second locking post 1054 disposed in the center of the fifth locking seat 1051 and capable of engaging with the hole-shaped portion; a conical locking cover 1053 is provided on one end of the second locking post 1054 relative to the end near the fan body connecting portion 101.

[0100] In this embodiment, the second locking pin can be locked to the perforated portion, and optionally, the two can be interference-fitted.

[0101] Please refer to Figure 6cOne embodiment of the third locking component shown is that the third locking component 105 includes: a sixth locking base 1055 and two L-shaped locking claws 1056 symmetrically arranged on one side of the sixth locking base 1055; the free ends of the two L-shaped locking claws 1056 are far apart from each other; a stop ring 1057 is provided on the end of the L-shaped locking claw 1056 that is relatively close to the sixth locking base 1055; a space is formed between the free end of the L-shaped locking claw 1056 and the stop ring 1057 that can lock the hole-shaped part.

[0102] The sixth card holder has two L-shaped claws symmetrically arranged, with the free ends of the two L-shaped claws being far apart from each other.

[0103] Optionally, a stop ring is provided on the first end of the sixth card holder.

[0104] The L-shaped claw and the stop ring form a space that can clamp the hole-shaped part.

[0105] In specific application scenarios, the perforated part is inserted into the outer wall of the two L-shaped jaws until the jaws and the stop ring clamp the edge of the perforated part.

[0106] Optionally, the claw includes: a support portion extending axially along the sixth card seat and a snap-fit ​​portion integrally formed with the support portion and extending away from the sixth card seat.
