Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a compact template mounting structure located below the seat frame. Background Technology

[0002] In the design and manufacturing of seats, especially automotive seats, the installation structure design of the fan module, wiring harness module, and ECU control 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 impacting the effective utilization of the space. Simultaneously, in traditional installation methods, the ECU control module needs to be fixed to the aforementioned large bracket using a separate mounting bracket. This not only increases installation difficulty but also adds to the overall weight of the seat. In the current automotive industry's increasing demands for lightweight design, this weight-increasing design is clearly not in line with development trends and will adversely affect the vehicle's energy consumption and other performance aspects. Furthermore, the installation of the fan in traditional structures lacks effective protective measures. Since there is no shielding structure under the fan, foreign objects under the seat can easily impact the fan. This can not only affect the normal operation and service life of the fan, but in severe cases, it may even damage the fan, thereby affecting the overall function of the seat, causing inconvenience and potential safety hazards to users. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a compact template installation structure located below the seat frame, so as to solve the problems of large space occupation, excessive weight and insufficient protection of the fan in the existing module installation structure.

[0004] To achieve the above objectives, this utility model proposes a compact template installation structure located below the seat frame, including a seat basin and a seat frame side panel, as well as a fan module, a wiring harness module, and an ECU control 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 vertical foot plates. The fan is fixed to the bottom surface of the fan bracket, and ventilation holes are provided on the fan bracket at the corresponding fan position. The wiring harness bracket is mounted on the bottom surface of the fan bracket via vertical foot plates and covers the fan. The seat wiring harness is fixed to the bottom surface of the wiring harness bracket during routing. The ECU control module has a box-shaped structure, which is located on the side of the fan bracket, and mounting ears are formed on both its left and right ends. The mounting ear on the side closer to the fan bracket is fixed to the fan bracket, and the mounting ear on the other side is fixed to the corresponding side panel of the seat frame.

[0005] In the above solution: the fan bracket is installed on the left end of the bottom surface of the basin, and the ECU control module is located on the right side of the fan bracket. This left-right distribution ensures that the components are arranged in an orderly manner under the basin, avoiding the problem of limited local space caused by the concentrated accumulation of components.

[0006] 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.

[0007] 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.

[0008] In the above solution: a connecting lug is welded to the inner wall of the seat frame side plate at the position corresponding to the mounting lug, and the seat frame side plate is fixedly connected to the mounting lug through the connecting lug. Welding the connecting lug at a specific position in advance provides a clear and fixed connection point for the installation of the ECU control module, which facilitates the positioning operation during installation.

[0009] In the above solution, the connecting lug and the corresponding mounting lug, and the fan bracket and the other mounting lug are all fixedly connected by screws, which is simple in structure and convenient for disassembly, assembly and maintenance.

[0010] In the above solution, the seat wiring harness is fixed to the wiring harness bracket by multiple Christmas tree clips, making the installation process simple and quick.

[0011] The beneficial effects of this utility model are as follows: 1. By using vertical foot plates to install the fan bracket and wiring harness bracket in layers, with the fan bracket installed on the bottom surface of the seat and the wiring harness bracket installed on the bottom surface of the fan bracket and covering the fan, a three-dimensional layered structure is formed, changing the traditional layout where the fan bracket and wiring 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 space-constrained traditional structural layouts. 2. The ECU control module is directly fixed to the fan bracket and the side plate of the seat frame through its own formed mounting ears, eliminating the need for additional mounting brackets and reducing the number of parts. 3. This structural design replaces the traditional large bracket integrated structure, avoiding the material consumption of the large bracket, reducing not only the overall manufacturing cost but also the weight of the seat. 4. The wiring harness bracket, covering the fan, can effectively block the impact of foreign objects under the seat on the fan, protecting the fan from damage and thus ensuring the normal working performance and service life of the fan.

[0014] Figure 3 This is an exploded schematic diagram of this utility model. Detailed Implementation

[0015] like Figure 1 As shown in Figure 3, a compact template installation structure located below the seat frame mainly consists of a seat basin 1, a seat frame side plate 2, a fan module, a wiring harness module, and an ECU control module 3.

[0016] The fan module includes a fan 4 and a fan bracket 5, and the wiring harness module includes a seat wiring harness and a wiring harness bracket 6. The fan bracket 5 is mounted on the bottom surface of the seat basin 1 via a vertical foot plate, and the fan 4 is fixed to the bottom surface of the fan bracket 5. Ventilation holes 51 are provided on the fan bracket 5 at positions corresponding to the fan 4. The wiring harness bracket 6 is mounted on the bottom surface of the fan bracket 5 via a vertical foot plate and covers the area below the fan 4. The seat wiring harness is fixed to the bottom surface of the wiring harness bracket 6 during routing.

[0017] The ECU control module 3 has a box-shaped structure and is located on the side of the fan bracket 5. Both its left and right ends are formed with mounting ears 31. The mounting ear 31 on the side closer to the fan bracket 5 is fixed to the fan bracket 5, and the mounting ear 31 on the other side is fixed to the side plate 2 of the corresponding side seat frame.

[0018] Ideally, the fan bracket 5 should be installed on the left side of the bottom surface of the basin 1, and the ECU control module 3 should be located on the right side of the fan bracket 5. This left-right distribution ensures that the components are arranged in an orderly manner under the basin 1, avoiding the problem of local space constraints caused by the concentrated accumulation of components.

[0019] Ideally, both the vertical base plates of the fan bracket 5 and the vertical base plates of the wiring harness bracket 6 have horizontal bends at their ends. The vertical base plate of the fan bracket 5 is welded to the bottom surface of the basin 1 through its horizontal bend, and the vertical base plate of the wiring harness bracket 6 is fixed to the fan bracket 5 with screws through 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.

[0020] Ideally, the fan 4 is fixed to the bottom surface of the fan bracket 5 by multiple rubber rivets. The rubber rivets have good elasticity and cushioning performance, which can significantly absorb the vibration generated when the fan is working. This not only reduces the transmission of the vibration of the fan 4 to the fan bracket 5 and the seat, 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.

[0021] Ideally, a connecting lug 21 is welded to the inner wall of the seat frame side plate 2 at the position corresponding to the mounting lug 31, and the seat frame side plate 2 is fixedly connected to the mounting lug 31 through the connecting lug 21. Welding the connecting lug 21 at a specific position in advance provides a clear and fixed connection point for the installation of the ECU control module 3, which facilitates the positioning operation during installation.

[0022] Ideally, the connecting lug 21 and the corresponding mounting lug 31, and the fan bracket 5 and the other mounting lug 31 are all fixedly connected by screws, which makes the structure simple and easy to disassemble, assemble and maintain.

[0023] Ideally, the seat wiring harness should be secured to the harness bracket 6 using multiple Christmas tree clips, making the installation process simple and quick.
