Description

Technical Field

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

[0002] In the design and manufacturing of seats, especially automotive seats, the installation structure of the fan module and wiring harness module has a crucial impact on the overall performance, space utilization, and safety of the seat. In traditional seats, the fan module and wiring harness module are typically installed using an integrated large bracket design. Specifically, the fan bracket and wiring harness bracket are arranged on the same plane and integrated into a single large bracket structure. While this design achieves centralized installation of components to some extent, it introduces significant space occupation problems. Because the large bracket itself occupies a large area, the entire module installation structure appears bulky under the seat, severely affecting the effective utilization of the space. Furthermore, the traditional structure lacks effective protective measures for the fan installation. Since there is no shielding structure under the fan, foreign objects under the seat can easily impact it. This not only affects the normal operating performance and lifespan of the fan, but in severe cases, it may even damage the fan, thus affecting the overall function of the seat, causing inconvenience and potential safety hazards to the user. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a cushion fan installation protection structure to solve the problems of large space occupation and insufficient protection of the fan in the existing installation structure.

[0004] To achieve the above objectives, this utility model proposes a seat cushion fan installation and protection structure, including a seat basin, a fan module, and a wiring harness module. The fan module includes a fan and a fan bracket, and the wiring harness module includes a seat wiring harness and a wiring harness bracket. The fan bracket is mounted on the bottom surface of the seat basin via a vertical foot plate. The fan is fixed to the bottom surface of the fan bracket. A ventilation hole is provided on the fan bracket at the position corresponding to the fan. The wiring harness bracket is mounted on the bottom surface of the fan bracket via a vertical foot plate and covers the area below the fan. The seat wiring harness is fixed to the bottom surface of the wiring harness bracket during routing.

[0005] In the above scheme: the fan bracket is fixed to the bottom of the basin by three vertical foot plates. The three vertical foot plates are set on the edge of the fan bracket and are spaced apart. The spaced foot plates can make the force between the fan bracket and the bottom of the basin more uniform and effectively disperse the vibration and stress generated during the operation of the fan.

[0006] In the above scheme: the plane area of ​​the wire harness bracket is smaller than the plane area of ​​the fan bracket. The wire harness bracket is fixed to the bottom surface of the fan bracket by two vertical foot plates, and the two vertical foot plates are respectively set on the left and right edges of the wire harness bracket. The structure is simple and easy to process.

[0007] In the above solution: both the vertical base plates of the fan bracket and the vertical base plates of the wiring harness bracket have horizontal bending sections at their ends. The vertical base plates of the fan bracket are welded to the bottom surface of the basin through their horizontal bending sections, and the vertical base plates of the wiring harness bracket are fixed to the fan bracket with screws through their horizontal bending sections. The horizontal bending sections provide a flat and regular connection surface for installation, which is easier to position and operate during welding or screw fixing compared to direct connection of the vertical base plates.

[0008] In the above solution: the fan is fixed to the bottom surface of the fan bracket by multiple rubber rivets. The rubber rivets have good elasticity and buffering performance, which can significantly absorb the vibration generated when the fan is working. This not only reduces the transmission of fan vibration to the fan bracket and the seat, but also avoids loosening or wear of various connecting parts caused by long-term vibration, extends the service life of the structure, and improves the quietness and comfort of the user when riding.

[0009] In the above solution: the wiring harness bracket is provided with multiple clip holes, and the seat wiring harness is connected to each clip hole one by one by multiple Christmas tree clips when it is routed, making the installation process simple and quick.

[0010] In the above solution, the fan bracket is also equipped with several clips that match the Christmas tree clips. For some low-end models, or in scenarios where customers do not require a seat cushion fan, this design demonstrates extremely high flexibility and practicality. In this case, the fan bracket can be directly converted into a wiring harness bracket without the need for an additional wiring harness bracket. This ingenious structural design not only effectively reduces costs but also simplifies the installation process.

[0011] The beneficial effects of this utility model are as follows: 1. By using vertical foot plates to install the fan bracket and wire harness bracket in layers, with the fan bracket installed on the bottom surface of the seat and the wire harness bracket installed on the bottom surface of the fan bracket and covering the area below the fan, a three-dimensional layered structure is formed. This changes the traditional layout where the fan bracket and wire harness bracket are integrated on the same plane. This design significantly reduces the area occupied on the plane, making more efficient use of the space under the seat frame and effectively solving the problems of bulky and cramped space in traditional structures. 2. The wire harness bracket covering the area below the fan can effectively block the impact of foreign objects under the seat on the fan, protecting the fan from damage, thereby ensuring the normal working performance and service life of the fan.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 This is an exploded schematic diagram of this utility model. Detailed Implementation

[0014] like Figure 1 As shown in Figure 2, a seat cushion fan installation and protection structure mainly consists of a seat basin 1, a fan module, and a wiring harness module. The fan module includes a fan 2 and a fan bracket 3, and the wiring harness module includes a seat wiring harness and a wiring harness bracket 4.

[0015] The fan bracket 3 is mounted on the bottom surface of the seat basin 1 via vertical foot plates. The fan 2 is fixed to the bottom surface of the fan bracket 3. The fan bracket 3 is provided with ventilation holes 31 corresponding to the positions of the fan 2. The wiring harness bracket 4 is mounted on the bottom surface of the fan bracket 3 via vertical foot plates and covers the area below the fan 2. When routing the seat wiring harness, it is fixed to the bottom surface of the wiring harness bracket 4.

[0016] Ideally, the fan bracket 3 is fixed to the bottom of the basin by three vertical foot plates. The three vertical foot plates are set on the edge of the fan bracket 3 and are spaced apart. The spaced foot plates can make the force between the fan bracket 3 and the bottom of the basin 1 more uniform and effectively disperse the vibration and stress generated by the fan 2 during operation.

[0017] Ideally, the plane area of ​​the wire harness bracket 4 is smaller than that of the fan bracket 3. The wire harness bracket 4 is fixed to the bottom surface of the fan bracket 3 by two vertical foot plates, and the two vertical foot plates are respectively set on the left and right edges of the wire harness bracket 4. The structure is simple and easy to process.

[0018] Ideally, both the vertical base plates of the fan bracket 3 and the vertical base plates of the wiring harness bracket 4 should have horizontal bends at their ends. The vertical base plate of the fan bracket 3 is welded to the bottom surface of the basin 1 via its horizontal bend, and the vertical base plate of the wiring harness bracket 4 is fixed to the fan bracket 3 with screws via its horizontal bend. The horizontal bends provide a flat and regular connection surface for installation, which is easier to position and operate during welding or screw fixing compared to direct connection of the vertical base plates.

[0019] Ideally, the fan 2 is fixed to the bottom surface of the fan bracket 3 by multiple rubber rivets. The rubber rivets have good elasticity and cushioning performance, which can significantly absorb the vibration generated by the fan 2 when it is working. This not only reduces the transmission of the vibration of the fan 2 to the fan bracket 3 and the seat 1, but also avoids the loosening or wear of the connecting parts caused by long-term vibration, extends the service life of the structure, and improves the quietness and comfort of the user when riding.

[0020] Ideally, the wiring harness bracket 4 should have multiple clip holes 5. When routing the seat wiring harness, multiple Christmas tree clips should be used to snap it into each clip hole 5, making the installation process simple and quick.

[0021] Ideally, the fan bracket 3 also has several clip holes 5 that match the Christmas tree clips. For some lower-spec models, or in scenarios where customers do not require a seat cushion fan, this design demonstrates high flexibility and practicality. In this case, the fan bracket 3 can be directly converted into a wiring harness bracket 4 without the need for an additional wiring harness bracket 4. This ingenious structural design not only effectively reduces costs but also simplifies the installation process.
