Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a backrest fan mounting structure and an automotive seat. Background Technology

[0002] In the automotive seating industry, backrest fans are widely used as a common ventilation device to improve passenger comfort, especially seat ventilation performance. The installation structure of the backrest fan has a crucial impact on its stability, ease of installation, and the rational utilization of the interior space of the car seat. Traditional backrest fan installation methods have many drawbacks. Currently, traditional backrest fans are usually fixed to the backrest frame using sheet metal parts, such as... Figure 1 As shown. Specifically, during installation, the sheet metal parts first need to be welded to the backrest frame. This welding process requires not only specialized welding equipment and technicians, but also inherent labor costs. After welding, the backrest fan is then fixed to the sheet metal parts with screws. From a cost perspective, adding sheet metal parts increases material costs, and the welding process also incurs additional labor costs. Furthermore, due to the volume and thickness of the sheet metal parts, the installation space required for adding them is substantial, further complicating the already limited interior space of the backrest and hindering the rational arrangement of other components, thus limiting the effective utilization of the car seat's interior space. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a backrest fan installation structure and a car seat to solve the problems of complex installation operation, high cost and large space occupation of traditional backrest fan installation structures.

[0004] To achieve the above objectives, this utility model proposes a backrest fan installation structure, including a fan, a fan bag, and a backrest foam. The back of the fan bag has a fan connection port, and a plastic plate is built into the fan bag corresponding to the fan connection port. The plastic plate has an installation hole communicating with the fan connection port. The fan is snapped into the installation hole by an inverted structure, thereby fixing it to the plastic plate and then to the back of the fan bag. After the left and right ends of the fan bag are sealed, they extend outward to form fixing lugs. Steel wires are pre-embedded in the backrest foam at the positions corresponding to the fixing lugs, and the fixing lugs are fixed to the corresponding steel wires by C-shaped nails.

[0005] In the above solution: the left and right ends of the air bag extend outward to form two fixed ears with vertical spacing. The fixed ears are provided with nail holes. By fixing at multiple points, the air bag is more firmly fixed on the backrest foam, reducing the possibility of shaking and displacement, and ensuring the overall stability of the fan and air bag system.

[0006] In the above scheme: a steel wire is pre-embedded in each of the fixed lugs corresponding to the backrest foam. The steel wire is a rectangular steel wire joined end to end, and the fixed lugs at both ends are fixed to the left and right ends of the steel wire with C-shaped nails. The joined rectangular steel wires form a closed loop structure. This structure has high strength and rigidity. When the air bag is subjected to external force, the steel wire can effectively bear and transmit these forces, distributing the local force to the entire steel wire loop, thereby improving the load-bearing capacity of the entire backrest fan installation structure. In addition, the rectangular steel wire also has a certain supporting effect on the backrest foam.

[0007] In the above solution, the plastic plate is pasted or sewn onto the inner wall of the back of the air bag, which has a simple structure and is easy to install.

[0008] In the above solution: the air bag includes a top part and a main part that are connected to each other. The fan is fixed on the top part of the air bag, and the fixing ears are located at both ends of the top part. The main part of the air bag is fixed to the backrest frame with screws. The structure is simple and easy to install.

[0009] This utility model also proposes an automobile seat, including the aforementioned backrest fan mounting structure.

[0010] The beneficial effects of this utility model are:

[0011] 1. The overall installation structure is simple in design, using a plastic sheet as the intermediate connecting component to connect the fan and the air bag. This not only secures the fan but also simplifies the installation process, reducing installation difficulty and cost. Simultaneously, the air bag extends outwards from both sealed ends to form fixing lugs, which are secured to the steel wires pre-embedded in the foam backrest using C-shaped nails. This connection method is simple, direct, and easy to operate. 2. Due to the use of snap-fit ​​and C-shaped nail fixing, disassembly is relatively easy when the fan needs maintenance or replacement, reducing maintenance time and cost. 3. It eliminates the need for sheet metal parts required in traditional installation methods, using only low-cost materials such as plastic sheets and C-shaped nails, effectively reducing material costs while meeting installation requirements. 4. No sheet metal welding is required, reducing the labor input of welding workers and further reducing labor costs. 5. The overall structure is compact, reducing the space occupied by the installation structure and providing more space for the arrangement of other components inside the car seat backrest, which is conducive to the rational planning and optimization of the seat's interior space.

[0012] Figure 1 It is a traditional backrest fan installation structure.

[0013] Figure 2 This is an assembly diagram of the fan and air bag.

[0014] Figure 3This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0015] like Figure 2 As shown in Figure 3, a backrest fan installation structure mainly consists of a fan 1, an air bag 2, and a backrest foam 3.

[0016] The back of the air bag 2 has a fan connection port. Inside the air bag 2, corresponding to the fan connection port, there is a plastic plate that is fixed in place. The plastic plate has mounting holes that communicate with the fan connection port. The fan 1 is snapped into the mounting holes by an inverted snap structure, thereby fixing it to the plastic plate and then to the back of the air bag 2.

[0017] After the left and right ends of the air bag 2 are sealed, it extends outward to form a fixed support ear 4. A steel wire is pre-embedded in the backrest foam 3 at the position corresponding to the fixed support ear 4. The fixed support ear 4 is fixed to the corresponding steel wire by C-shaped nails.

[0018] Ideally, the air bag 2 extends outward at both ends to form two fixed supports 4 with vertical spacing. The fixed supports 4 are provided with nail holes. By fixing at multiple points, the air bag 2 is more firmly fixed on the backrest foam 3, reducing the possibility of shaking and displacement, and ensuring the overall stability of the fan 1 and air bag 2 system.

[0019] Ideally, a steel wire should be pre-embedded within the backrest foam 3, corresponding to each fixed bracket 4. This steel wire is a rectangular wire joined end-to-end, with the fixed brackets 4 at both ends secured to the left and right ends of the wire using C-shaped nails. The joined rectangular steel wires form a closed-loop structure, which possesses high strength and rigidity. When the air bag 2 is subjected to external force, the steel wire can effectively bear and transmit these forces, distributing the localized stress across the entire wire loop. This improves the load-bearing capacity of the entire backrest fan installation structure, and the rectangular steel wire also provides some support for the backrest foam 3.

[0020] Ideally, the plastic sheet should be glued or sewn onto the inner back wall of the air bag 2, which is simple in structure and easy to install.

[0021] Preferably, the air bag 2 includes a top part 21 and a main body part 22 that are connected to each other. The fan 1 is fixed to the top part 21 of the air bag 2, and the fixing lugs 4 are located at both ends of the top part 21. The main body part 22 of the air bag 2 is fixed to the backrest frame by screws. The structure is simple and easy to install.

[0022] A car seat, including the aforementioned backrest fan mounting structure.
