[0031] The following further describes the specific embodiments of the present invention with reference to the drawings.

[0032] An embodiment of the present invention provides a waterproof method for the second-row seat plug-ins. As Figures 1 to 4As shown in the figure, the waterproof method includes the following steps: S01, conduct a sprinkling test to determine the wet area and dry area on the second-row seat 100; S02, based on the characteristics of the plug 1, determine whether the plug 1 can be set in the dry area; S03, according to the judgment result, for the plug 1 that can be set in the dry area, set it in the dry area, and for the plug 1 that cannot be set in the dry area, set it in the transformed dry area formed by transforming the wet area. According to the present application, based on the structure of the sprinkling test, finally, the plug 1 is placed in the dry area and the transformed dry area, reducing the risk of water ingress into the plug, avoiding water ingress, and ensuring the safe use of the plug.

[0033] In the waterproof method, first of all, a sprinkling test needs to be carried out to judge the wet area and dry area on the second-row seat 100, so as to provide a location basis for the subsequent installation of the plug 1. In the present application, by analyzing the structural characteristics of the second-row seat 100, it can be obtained that water can enter through the mounting bracket 4 and ISOFIX (the area where the child seat is connected to the vehicle seat system) 5 at the seam between the seat cushion 2 and the backrest 3 of the second-row seat 100, or it can penetrate through the seat tail connection 6. Therefore, the test includes sprinkling water on the second-row seat, and the water enters through the mounting bracket 4 and ISOFIX 5 at the seam between the seat cushion 2 and the backrest 3 of the second-row seat 100. The test also includes sprinkling water in the trunk, and the water penetrates through the seat tail connection 6 and flows forward along the sound insulation pad 7 to the lower area of the seat cushion 2. In Figure 2 the upper figures of the above figure and Figure 3, the dotted lines mark the water flow directions in the test. Refer to Figure 2 and 3 , the positions where the water flows through and the positions where the water accumulates in the sprinkling test can be judged as the wet area, and vice versa as the dry area. It should be noted that the second-row seat 100 mainly includes a seat cushion 2, a backrest 3, and a Y-direction extending mounting bracket 4 arranged between the two. Among them, the seat cushion 2 includes a seat cushion skeleton 21 and a seat cushion soft body 22 arranged on the seat cushion skeleton 21. A sound insulation pad 7 is also arranged under the seat cushion 2 of the second-row seat 100.

[0034] After determining the wet area and dry area on the second-row seat 100, according to the self-characteristics of the plug 1, determine whether the plug 1 can be set in the dry area. The plugs on the second-row seat 100 mainly include: the first connector, the second connector, the third connector, and the fourth connector. Among them, there are three fourth connectors, specifically the connector 11 where the SBR (pressure sensing connector) is docked with the heating pad; the first connector is the connector 12 for docking the second-row seat with the vehicle body; the second connector is the connector 13 for docking the 60% backrest with the seat cushion; the third connector is the connector 14 for docking the 40% backrest with the seat cushion. The self-characteristics of the plug 1 mainly include the routing relationship of the wire harness and the volume of the plug 1 itself.

[0035] For the three connectors 11 for docking the SBR with the heating pad, considering the wiring harness connection relationship and its own volume, it can be allowed to be set on the seat cushion frame 21 under the seat cushion soft body 22. That is to say, there is no obstacle in the wiring harness layout, and its own volume does not cause interference with other components at this position, then the connector 11 for docking the SBR with the heating pad can be set on the seat cushion frame 21.

[0036] Figure 4 The upper figure in [[ ]] is used as a comparative example, showing that the connector 11 for docking the SBR with the heating pad is relatively close to the sound insulation pad 7 after being fixed, and there is a risk of water ingress for this connector 11 for docking the SBR with the heating pad. Therefore, for this type of plug 1, the layout position of the plug 1 can be changed, as indicated by the arrowed line in [[ ]], and away from the wet area. Specifically, as shown in the lower figure in [[ ]], by raising the Z-direction (referring to the vehicle, consistent with the height direction of the vehicle) position of the plug 1, it is ensured that the plug 1 is located in the dry area. That is to say, the plug 1 is set in the dry area at the first Z-height from the sound insulation pad 7. Preferably, the size of the first height is 5 - 13 mm, for example, 10 mm. This setting can effectively ensure that the plug 1 is within the dry area range, thereby avoiding water ingress. It should be noted that during the process of raising the fixing position of the plug 1, interference may occur with the seat cushion soft body 22, and thus an avoidance space 23 can be set on the seat cushion soft body 22 to ensure the installation position of the corresponding plug. It is easy to understand that the three connectors 11 for docking the SBR with the heating pad are spaced apart in the Y-direction (referring to the vehicle, consistent with the left-right direction of the vehicle) of the seat cushion frame 21 of the second-row seat 100. The layout of the remaining connectors 11 for docking the SBR with the heating pad refers to the layout of the connector 11 for docking the SBR with the heating pad in [[ ]]. Figure 4 The arrowed line in [[ ]] indicates, and away from the wet area. Specifically, as Figure 4 shown in the lower figure in [[ ]], by raising the Z-direction (referring to the vehicle, consistent with the height direction of the vehicle) position of the plug 1, it is ensured that the plug 1 is located in the dry area. That is to say, the plug 1 is set in the dry area at the first Z-height from the sound insulation pad 7. Preferably, the size of the first height is 5 - 13 mm, for example, 10 mm. This setting can effectively ensure that the plug 1 is within the dry area range, thereby avoiding water ingress. It should be noted that during the process of raising the fixing position of the plug 1, interference may occur with the seat cushion soft body 22, and thus an avoidance space 23 can be set on the seat cushion soft body 22 to ensure the installation position of the corresponding plug. It is easy to understand that the three connectors 11 for docking the SBR with the heating pad are spaced apart in the Y-direction (referring to the vehicle, consistent with the left-right direction of the vehicle) of the seat cushion frame 21 of the second-row seat 100. The layout of the remaining connectors 11 for docking the SBR with the heating pad refers to the layout of the connector 11 for docking the SBR with the heating pad in [[ ]]. Figure 4 the layout of the connector 11 for docking the SBR with the heating pad in [[ ]].

[0037] For the three plugs 1, namely the connector 12 for docking the second-row seat with the vehicle body, the connector 13 for docking the 60% backrest with the seat cushion, and the connector 14 for docking the 40% backrest with the seat cushion, the wiring harness connection relationship restricts that they cannot be set under the seat cushion soft body 22, but can be set at the rear side (referring to the vehicle) of the seat cushion soft body 22. However, if the plugs 1 are set as shown in the upper figure in [[ ]] and the upper figure in [[ ]], the connector 12 for docking the second-row seat with the vehicle body, the connector 13 for docking the 60% backrest with the seat cushion, and the connector 14 for docking the 40% backrest with the seat cushion obviously have a risk of water ingress. Then, artificial modification is required to make the plug 1 located in the modified dry area. For example, a modified dry area can be constructed by setting a water-blocking member 8. Figure 2 the upper figure in [[ ]] and Figure 3 the upper figure in [[ ]] to set the plug 1, the connector 12 for docking the second-row seat with the vehicle body, the connector 13 for docking the 60% backrest with the seat cushion, and the connector 14 for docking the 40% backrest with the seat cushion obviously have a risk of water ingress. Then, artificial modification is required to make the plug 1 located in the modified dry area. For example, a modified dry area can be constructed by setting a water-blocking member 8.

[0038] Taking Figure 3 the connector 12 for docking the second-row seat with the vehicle body in [[ ]] as an example, as Figure 3As shown in the upper figure in [reference], if the second-row seat-to-body docking connector 12 is arranged close to the sound insulation pad 7, it is very easy for water to enter and cause damage to the plug 1. Therefore, it is necessary to transform the wet area into a modified dry area, and then the second-row seat-to-body docking connector 12 can be arranged in the modified dry area, as Figure 3 shown in the lower figure in [reference].

[0039] In one embodiment, a water-blocking member 8 can be provided to protect the plug 1. Specifically, as Figure 3 shown in the lower figure in [reference], the water-blocking member 8 is an L-shaped plate bending member and includes a first side 81 and a second side 82. The first side 81 of the bending member is connected to the mounting bracket 4 of the second-row seat, for example, by welding. The second side 82 of the bending member is arranged 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-to-body docking connector 12 is fixed to the second side 82 and is located in the inner space on the back side (here, the back side refers to the side opposite to the side facing the inflow of water) of the water-blocking member 8. Thus, after installation, the second side 82 is located upstream of the water flow for sprinkling relative to the second-row seat-to-body docking connector 12, and the second side 82 plays a role in protecting the second-row seat-to-body docking connector 12. In addition, a flanging 83 extending away from the second side 82 is provided on the first side 81, and the flanging 83 is in pressure contact with the seat cushion soft body 22 of the seat cushion 2 of the second-row seat 100 to form a structure similar to a seal to prevent flowing water from flowing through the gap between the first side 81 and the seat cushion soft body 22 to the second-row seat-to-body docking connector 12.

[0040] Preferably, the seat cushion soft body 22 of the second-row seat is in pressure contact with the mounting bracket 4. By this setting, it can also prevent flowing water from flowing through the gap between the seat cushion soft body 22 and the mounting bracket 4 to the second-row seat-to-body docking connector 12, thereby ensuring the safety of the seat cushion soft body 22 of the second-row seat.

[0041] It is easy to understand that the self-width of the water-blocking member 8, especially the width of the second side 82, should protrude from the second-row seat-to-body docking connector 12 in the Y direction. Thus, the L-shaped setting of the water-blocking member 8 with the second side 82 facing the flowing water direction can form waterproofing in the Z direction; through the pressure contact between the seat cushion soft body 22 and the mounting bracket 4, and the pressure contact between the flanging 83 and the seat cushion soft body 22, waterproofing in the X direction can be formed, and the self-width of the water-blocking member 8 can achieve a water-blocking effect in the Y direction. It can be seen that through the above settings, the working environment of the corresponding plug 1 can be ensured.

[0042] In addition, the waterproofing methods for the 60% backrest and seat cushion docking connector 13 and the 40% backrest and seat cushion docking connector 14 are the same as or similar to the waterproofing method for the second-row seat and body docking connector 12, both of which are to set up a water-blocking member 8 to construct a modified dry area to ensure the installation environment, which will not be elaborated here. Considering the convenience and economy of wire harness connection, the second-row seat and body docking connector 12 is located in the middle part of the mounting bracket of the second-row seat in the Y direction; while the 60% backrest and seat cushion docking connector 13 is located in the middle part of the mounting bracket of the second-row seat in the Y direction and is adjacent to the second-row seat and body docking connector; the 40% backrest and seat cushion docking connector 14 is located at one end of the mounting bracket of the second-row seat in the Y direction.

[0043] In addition, it is also necessary to compare the size of the plug 1 itself and the installation space. If the installation space is relatively small and the volume of the plug itself is relatively large, for example, as Figure 3 shown by the second-row seat and body docking connector 12, its installation position is relatively close to the sound insulation pad 7. If there is a relatively large amount of water entering the carriage and the water accumulates on the sound insulation pad 7, this second-row seat and body docking connector 12 also has a risk of water ingress. Therefore, in order to improve the water ingress prevention ability of a similar plug 1, a drain groove 71 can be provided on the sound insulation pad 7, as shown in the lower figure of Figure 2 . The drain groove 71 is in the shape of a groove, used to collect water flow and guide the water flow. The dotted line with an arrow in the figure represents the direction of water flow. In addition, the drain groove 71 is used to communicate with the opening 72 on the sound insulation pad 7 provided in the seat belt buckle installation area or the opening 72 of the sound insulation pad 7 in the seat mounting foot area, so as to drain the accumulated water from the sound insulation pad 7 and prevent the water from accumulating and affecting the second-row seat and body docking connector 12.

[0044] This application also relates to a second-row seat 100 and a vehicle including the second-row seat 100. Among them, as shown in Figures 2 to 4 , a dry area and a wet area are formed on the second-row seat 100 according to the sprinkler test results. Among them, as described above, in the sprinkler test, the position where the water flows through or the position where the water accumulates is the wet area, while the position where the water does not flow through and 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. A plug 1 is provided on the second-row seat 100. The plug 1 is arranged in the dry area or the modified dry area to prevent the plug 1 from getting water and ensure safety. The plug 1 includes a first connector, a second connector, a third connector and a fourth connector. Among them, there are three fourth connectors, specifically the connector 11 for the SBR (pressure sensing connector) to dock with the heating pad; the first connector is the second-row seat and body docking connector 12; the second connector is the 60% backrest and seat cushion docking connector 13; the third connector is the 40% backrest and seat cushion docking connector 14.

[0045] In a specific embodiment, the connector 11 for docking the SBR with the heating pad is arranged in a dry area at a first height in the Z direction from the sound insulation pad. Moreover, the three connectors 11 for docking the SBR with the heating pad are distributed at intervals in the Y direction on the seat cushion frame 21 of the seat cushion 2 of the second-row seat 100. The connector 12 for docking the second-row seat with the vehicle body is located in the middle part of the mounting bracket 4 of the second-row seat 100 in the Y direction and is arranged in the modified dry area formed by the water baffle 8. The connector 13 for docking 60% of the backrest with the seat cushion is located in the middle part of the mounting bracket 4 of the second-row seat 100 in the Y direction, is adjacent to the connector 12 for docking the second-row seat with the vehicle body, and is arranged in the modified dry area formed by the water baffle 8. The connector 14 for docking 40% of the backrest with the seat cushion is located at one end of the mounting bracket 4 of the second-row seat 100 in the Y direction and is arranged in the modified dry area formed by the water baffle 8.

[0046] In this application, the layout of the plug 1 on the second-row seat 100 is optimized by the waterproof method of the second-row seat plug-ins, ensuring that the plug 1 is in a dry area or a modified dry area, preventing the plug 1 from getting waterlogged, guaranteeing the use safety of the plug 1, and expanding the scope of use of the vehicle.

[0047] In addition, in this 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. Moreover, orientation terms such as "front" and "rear" are referenced based on the vehicle's own orientation.

[0048] The above are only the principles and preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, based on the principles of the present invention, several other variations can also be made, which should also be regarded as the protection scope of the present invention.
