Description

Technical Field

[0001] This utility model relates to the field of automotive body technology, and in particular to a sheet metal sealing structure for the side of a charging port. Background Technology

[0002] New energy vehicles are categorized into pure electric vehicles, range-extended electric vehicles, plug-in hybrid electric vehicles, and non-plug-in hybrid electric vehicles. Plug-in hybrid electric vehicles combine the advantages of gasoline and electric vehicles and are increasingly favored by the market. In addition to a gasoline filler cap, plug-in hybrid electric vehicles also have a power outlet for connecting an external cable to charge the battery.

[0003] Charging ports are primarily located in the front grille, front fender, or rear side panel. For plug-in hybrid electric vehicles, since the combustion engine is located in the front compartment, the charging port is generally located on the right rear side panel, corresponding to the fuel filler cap. Currently, most charging port boxes use an external drainage system, with a few using an internal drainage system. Externally drained charging port boxes have a sloping bottom, allowing rainwater to drain through the sloping surface. The vehicle body requires a tight seal between the charging port box and the charging base. Internally drained charging port boxes have additional drainage holes connected to a drain pipe, allowing water inside the box to drain to the outside of the vehicle.

[0004] With the integration and development of technology, hybrid vehicles on the market are now equipped with integrated fast and slow charging. The charging port is approximately 150mm in size. Existing internal and external drainage-type charging port box structures, due to size limitations, cannot effectively seal the new charging port, thus affecting the vehicle's corrosion resistance. Therefore, it is necessary to invent a sheet metal sealing structure for the charging port sidewall. Utility Model Content

[0005] The purpose of this invention is to provide a sheet metal sealing structure for the side of the charging port, which is used to waterproof and seal large-sized charging sockets, ensuring the corrosion resistance of the vehicle body.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A sheet metal sealing structure for a charging port side panel includes a sealing seat fixedly connected between the outer wheel arch panel and the outer side panel. The sealing seat is fitted onto the charging port box. A connecting boss is provided on the side of the sealing seat facing outwards from the vehicle. A first charging port groove is provided on the connecting boss. A sealing groove is provided around the first charging port groove. Sealing adhesive is provided in the sealing groove and fixedly connected to the inner side of the outer side panel. The side of the sealing seat facing inwards from the vehicle is fixedly connected to the outer wheel arch panel.

[0008] Preferably, in conjunction with the above scheme, a charging base fixing plate is fixedly connected to the outer plate of the wheel cover, and the charging base fixing plate is used to fix the charging base.

[0009] Preferably, in conjunction with the above scheme, the charging base fixing plate is provided with a second charging port slot.

[0010] Preferably, in conjunction with the above scheme, the charging base fixing plate is fixedly connected to the outer plate of the wheel cover by welding.

[0011] Preferably, in conjunction with the above scheme, the sealing seat is fixedly connected to the outer plate of the wheel cover by welding.

[0012] Preferably, in conjunction with the above scheme, a drainage hole is provided at the bottom of the charging port box on the side facing the inside of the vehicle.

[0013] Preferably, in conjunction with the above scheme, a charging port is provided on the outer side panel at the position corresponding to the first charging port slot.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a sheet metal sealing structure for the charging port side panel. By setting a sealing seat between the outer wheel arch panel and the outer side panel, and using a sealing groove on the sealing seat to glue and seal it to the outer side panel, a sealed space is formed to prevent water from entering the sheet metal cavity inside the vehicle body. Water inside the charging port box can be directly discharged through the drainage holes of the outer wheel arch panel, solving the drainage and sealing problems in a limited space.

[0015] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] like Figures 3 to 7 The diagram illustrates a sheet metal sealing structure for a charging port side panel. A sealing seat 3 is fixedly connected between the outer wheel arch panel 1 and the outer side panel 2. The sealing seat 3 is fitted onto the charging port box 5. A connecting boss 31 protrudes from the side of the sealing seat 3 facing outwards, and a first charging port groove 32 is provided on the connecting boss 31 to facilitate the insertion and positioning of the charging head. A sealing groove 33 is provided around the first charging port groove 32, and a sealant 34 is provided in the sealing groove 33 and fixedly connected to the inner side of the outer side panel 2. The sealing seat 3 is fixedly connected to the outer wheel arch panel 1 from the side facing inwards. The sealant 34 can be a commercially available sealing expansion adhesive or a thermosetting shock-absorbing expansion adhesive. After electrophoresis and heating, it expands and bonds the outer side panel 2 and the sealing seat 3 together, preventing collision and vibration between the two rigid materials while ensuring a sealing effect. This sealant can be provided by Hubei Huitian New Material Co., Ltd., and the model can be 7150 (HT805).

[0024] To facilitate the installation of the fast and slow charging dock, a charging dock fixing plate 4 is fixedly connected to the outer plate 1 of the wheel cover. The charging dock fixing plate 4 is used to fix the charging dock 5. The charging dock fixing plate 4 is fixedly connected to the outer plate 1 of the wheel cover by welding through three sets of connecting edges.

[0025] To facilitate the insertion and positioning of the charging head, the charging base fixing plate 4 is provided with a second charging port slot 41.

[0026] To ensure the stability of the connection between the charging base fixing plate 4 and the wheel cover outer plate 1, the charging base fixing plate 4 is fixedly connected to the wheel cover outer plate 1 by welding.

[0027] To ensure the stability of the connection between the sealing seat 3 and the outer plate of the wheel cover 1, the sealing seat 3 is fixedly connected to the outer plate of the wheel cover 1 by welding.

[0028] To better seal and drain the charging port box 5, a drain hole 51 is provided on the bottom side of the charging port box 5 facing the inside of the vehicle. Water is drained through the drain hole 51 towards the vehicle's mudguard. The charging port box 5 is snap-fitted to the outer side panel 2.

[0029] To facilitate the insertion and positioning of the charging head and the installation of the charging port cover, a charging port 21 is provided on the outer side panel 2 at the position corresponding to the first charging port slot 32.

[0030] This utility model is applicable to the charging port box installation structure for both internal and external drainage, and can effectively seal the side panel and wheel arch panel, forming a sealed space that can prevent water vapor from entering the vehicle body.
