[0031] The specific embodiments of the present application will be further described below with reference to the accompanying drawings.

[0032] An embodiment of the present application provides a waterproof method of a second-row seat plug-in part. As shown in Figures 1 to 4As shown, the waterproof method includes the following steps: S01, performing a water spraying test to determine the wet area and dry area on the second-row seat 100; S02, judging whether the insert 1 can be set to the dry area according to the characteristics of the insert 1; S03, according to the judgment result, setting the insert 1 to the dry area for the insert 1 that can be set to the dry area, and setting the insert 1 to a modified dry area formed by modifying the wet area for the insert 1 that cannot be set to the dry area. According to the present application, the insert 1 is finally placed in the dry area and the modified dry area according to the water spraying test structure, the risk of water entering the insert is reduced, water entering is avoided, and the safety of use of the insert is ensured.

[0033] In the waterproof method, first, a water spraying test is performed to determine the wet area and dry area on the second-row seat 100 to provide a position basis for subsequent installation of the insert 1. In the present application, by analyzing the structural characteristics of the second-row seat 100, it can be found that water can enter through the installation support 4 at the gap between the seat cushion 2 and the backrest 3 of the second-row seat 100, and the ISOFIX 5, or can penetrate through the seat tail joint 6. Therefore, the test includes spraying water on the second-row seat, and the water enters through the installation support 4 at the gap between the seat cushion 2 and the backrest 3 of the second-row seat 100, and the ISOFIX 5. The test also includes spraying water on the trunk, and the water penetrates through the seat tail joint 6 and flows along the sound insulation pad 7 to the area below the seat cushion 2. In Figure 2 The water flow direction in the test is indicated by the dashed line in the upper part of FIG. 2 and the upper part of FIG. 3. Referring to Figure 2 and 3 The positions through which water flows and the positions where water accumulates in the water spraying test can be determined as the wet area, and vice versa. It should be noted that the second-row seat 100 mainly includes the seat cushion 2, the backrest 3, and the Y-directionally extending installation support 4 arranged between the seat cushion 2 and the backrest 3. Among them, the seat cushion 2 includes a seat cushion framework 21 and a seat cushion soft body 22 arranged on the seat cushion framework 21. The second-row seat 100 is further provided with a sound insulation pad 7 below the seat cushion 2.

[0034] After determining the wet area and dry area on the second-row seat 100, it is judged whether the insert 1 can be set to the dry area according to the characteristics of the insert 1. The insert on the second-row seat 100 mainly includes: a first connector, a second connector, a third connector, and a fourth connector. Among them, the fourth connector is three, specifically a connector 11 for the butt joint of the SBR (pressure-sensitive connector) and the heating pad; the first connector is a second-row seat and vehicle body butt joint connector 12; the second connector is a 60% backrest and seat cushion butt joint connector 13; the third connector is a 40% backrest and seat cushion butt joint connector 14. The characteristics of the insert 1 mainly include the relationship between the wire harness and the volume of the insert 1 itself.

[0035] For the three connectors 11 that interface between the SBR and the heating pad, considering the wiring harness connection relationship and their own size, they can be allowed to be installed on the seat frame 21 below the seat cushion soft body 22. That is to say, there is no obstacle to the wiring harness layout, and their own size in this position will not cause interference with other components, so the connectors 11 that interface between the SBR and the heating pad can be installed on the seat frame 21.

[0036] Figure 4 The upper diagram serves as a comparative example, showing that the connector 11, where the SBR mates with the heating pad, is relatively close to the sound insulation pad 7 after being fixed. This connector 11 poses a risk of water ingress. Therefore, for this type of plug-in 1, its placement can be changed by... Figure 4 The arrowed lines indicate areas away from wet areas. Specifically, such as... Figure 4 As shown in the diagram below, by raising the Z-axis position of plug 1 (with reference to the vehicle, consistent with the vehicle's height direction), plug 1 is ensured to be located in the dry zone. That is, plug 1 is positioned in the dry zone at a first Z-axis height from the sound insulation pad 7. Preferably, the first height is 5-13 mm, for example, 10 mm. This setting effectively ensures that plug 1 is within the dry zone, thus preventing water ingress. It should be noted that during the raising of plug 1's fixed position, interference with the seat cushion soft body 22 may occur. Therefore, a clearance space 23 can be provided on the seat cushion soft body 22 to ensure the installation position of the corresponding plug. It is easy to understand that the three SBR connectors 11 that interface with the heating pad are spaced apart in the Y-axis (with reference to the vehicle, consistent with the vehicle's left-right direction) of the seat cushion frame 21 of the second-row seat 100. The remaining SBR connectors 11 are arranged as follows... Figure 4 The layout of connector 11, which connects the SBR to the heating pad.

[0037] Regarding the three connectors 1—the second-row seat-to-body connector 12, the 60% backrest-to-seat cushion connector 13, and the 40% backrest-to-seat cushion connector 14—the wiring harness connection restricts their placement below the seat cushion soft body 22, but they can be placed behind the seat cushion soft body 22 (with reference to the vehicle). However, if... Figure 2 The above image and Figure 3 The above diagram shows that the connectors 11 (for the second-row seats and body), 12 (for the second-row seats), 13 (for the 60% backrest and seat cushion), and 14 (for the 40% backrest and seat cushion) are obviously at risk of water ingress. Therefore, modifications are needed to position connector 1 within a modified dry zone. For example, this can be achieved by installing a water-blocking component 8 to create a modified dry zone.

[0038] by Figure 3 Taking the second-row seat and body docking connector 12 as an example, Figure 3As shown in the diagram above, if the second-row seat-to-body connector 12 is located near the sound insulation pad 7, water can easily enter and damage the connector 1. Therefore, it is necessary to modify the wet area to transform it into a modified dry area. The second-row seat-to-body connector 12 can then be placed within this modified dry area, as shown below. Figure 3 The image below is shown.

[0039] In one embodiment, a water-blocking component 8 can be provided to protect the insert 1. Specifically, as shown in the example... Figure 3 As shown in the lower figure, the water-blocking component 8 is an L-shaped bent sheet metal component, including a first side 81 and a second side 82. The first side 81 of the bent component is connected to the mounting bracket 4 of the second-row seat, for example, by welding. The second side 82 of the bent component is located at the lower end of the first side 81, and the free end of the second side 82 extends towards the front end of the second-row seat 100 relative to the fixed end. The second-row seat and body docking connector 12 is fixed to the second side 82 and is located in the space inside the back side of the water-blocking component 8 (here, the back side refers to the side opposite to the side facing the water inflow). Thus, after installation, the second side 82 is located upstream of the water flow corresponding to the second-row seat and body docking connector 12, and the second side 82 serves to protect the second-row seat and body docking connector 12. Additionally, a flange 83 extending away from the second side 82 is provided on the first side 81. The flange 83 presses against the cushion soft body 22 of the second-row seat 100 to form a seal-like structure, preventing water from flowing through the gap between the first side 81 and the cushion soft body 22 to the second-row seat and body docking connector 12.

[0040] Preferably, the cushion soft body 22 of the second-row seats is pressurized against the mounting bracket 4. This arrangement also prevents water from flowing through the gap between the cushion soft body 22 and the mounting bracket 4 to the second-row seat and the vehicle body docking connector 12, thereby ensuring the safety of the cushion soft body 22 of the second-row seats.

[0041] It is easy to understand that the width of the water-blocking component 8, especially the width of the second side 82, should protrude beyond the second-row seat and vehicle body connector 12 in the Y direction. Therefore, the L-shaped design of the water-blocking component 8, with the second side 82 facing the direction of water flow, can achieve Z-direction waterproofing; through the pressure contact between the seat cushion soft body 22 and the mounting bracket 4, and the pressure contact between the flange 83 and the seat cushion soft body 22, X-direction waterproofing can be achieved; and the width of the water-blocking component 8 itself can achieve a water-blocking effect in the Y direction. It is evident that the above design ensures the working environment of the corresponding plug-in 1.

[0042] In addition, the waterproof method of the 60% backrest and cushion interface connector 13 and the 40% backrest and cushion interface connector 14 is the same as or similar to the waterproof method of the second-row seat and vehicle interface connector 12, that is, a water-blocking member 8 is arranged to form a modified dry area for ensuring the installation environment, which will not be described here. Considering the convenience of wiring harness connection and economy, the second-row seat and vehicle interface connector 12 is located at the middle part of the installation support of the second-row seat in the Y direction; the 60% backrest and cushion interface connector 13 is located at the middle part of the installation support of the second-row seat in the Y direction and adjacent to the second-row seat and vehicle interface connector; and the 40% backrest and cushion interface connector 14 is located at one end of the installation support of the second-row seat in the Y direction.

[0043] In addition, the size of the plug-in 1 itself and the installation space also need to be compared. If the installation space is relatively small and the size of the plug-in is relatively large, for example, the second-row seat and vehicle interface connector 12 as shown in Figure 3 is relatively close to the sound insulation pad 7 at the installation position. If there is a lot of water in the vehicle cabin, the water will accumulate on the sound insulation pad 7, and the second-row seat and vehicle interface connector 12 also has the risk of water ingress. Therefore, in order to improve the water-proofing ability of the plug-in 1, a drainage groove 71 can be arranged on the sound insulation pad 7, as shown in the lower part of Figure 2 . The drainage groove 71 is a groove shape for collecting water flow and guiding water flow. The arrowed dashed line in the figure represents the direction of water flow. In addition, the drainage groove 71 is used to communicate with the opening 72 arranged on the sound insulation pad 7 in the safety belt buckle installation area or the opening 72 of the sound insulation pad 7 in the seat installation foot area, for draining the accumulated water out of the sound insulation pad 7, avoiding the accumulation of water affecting the second-row seat and vehicle interface connector 12.

[0044] The present application also relates to a second-row seat 100 and a vehicle comprising the same. As shown in Figures 2 to 4 , the second-row seat 100 is divided into a dry area and a wet area according to the results of the water spray test. As described above, in the water spray test, the position where water flows through or the position where water accumulates is the wet area, and the position where water does not flow through and the position where water does not accumulate is the dry area. The wet area can also be modified to block the water flow to form a modified dry area. The second-row seat 100 is provided with a plug-in 1. The plug-in 1 is arranged in the dry area or the modified dry area to prevent water from entering the plug-in 1 and ensure safety. The plug-in 1 comprises a first connector, a second connector, a third connector and a fourth connector. The fourth connector is three, specifically the SBR (pressure-sensitive connector) and heating pad interface connector 11; the first connector is the second-row seat and vehicle interface connector 12; the second connector is the 60% backrest and cushion interface connector 13; and the third connector is the 40% backrest and cushion interface connector 14.

[0045] In a specific embodiment, the SBR and heating pad interfacing connector 11 is arranged in the dry zone at a first height from the soundproofing pad 7Z. Furthermore, three SBR and heating pad interfacing connectors 11 are arranged in the Y direction at intervals on the seat cushion framework 21 of the seat cushion 2 of the second-row seat 100. The second-row seat and vehicle body interfacing connector 12 is arranged in the Y direction at the middle portion of the mounting bracket 4 of the second-row seat 100 and is arranged in the modified dry zone formed by the water-blocking member 8. The 60% backrest and seat cushion interfacing connector 13 is arranged in the Y direction at the middle portion of the mounting bracket 4 of the second-row seat 100 and is adjacent to the second-row seat and vehicle body interfacing connector 12, and is arranged in the modified dry zone formed by the water-blocking member 8. The 40% backrest and seat cushion interfacing connector 14 is arranged in the Y direction at one end of the mounting bracket 4 of the second-row seat 100 and is arranged in the modified dry zone formed by the water-blocking member 8.

[0046] The present application optimizes the arrangement of the insert 1 on the second-row seat 100 by the waterproof method of the second-row seat insert, ensures that the insert 1 is in the dry zone or the modified dry zone, avoids water entering the insert 1, ensures the safety of the use of the insert 1, and improves the use range of the vehicle.

[0047] In addition, in the present application, the X direction is consistent with the front-rear direction of the vehicle, the Y direction is consistent with the left-right direction of the vehicle, and the Z direction is consistent with the up-down direction of the vehicle. In addition, the orientation terms "front", "rear", and the like are all referenced to the orientation of the vehicle itself.

[0048] The above is only the principles and preferred embodiments of the present application. It should be noted that, for those skilled in the art, on the basis of the principles of the present application, a number of other variants can also be made, which should also be considered as falling within the scope of protection of the present application.
