Description

Technical Field

[0001] The utility model relates to a charging power connection assembly inside an electric vehicle, in particular to a non-wire power connection assembly that matches the vehicle body. Background Art

[0002] New energy vehicles (electric vehicles) usually have a battery pack configured at the bottom of the vehicle body, and a charging socket is provided on the vehicle shell adjacent to the tire. The charging socket and the battery pack are connected to each other through copper wires arranged inside the vehicle body to form a power transmission line. Since copper wires are relatively heavy and costly, and the cost per unit of driving range is an important indicator for new energy vehicles. In order to improve the driving range and reduce costs, lightweight design is an inevitable trend. Since aluminum can achieve a 40% weight reduction and save about 30% of the cost under equivalent current transmission conditions, replacing the original copper wires with aluminum bars is a feasible alternative.

[0003] However, the aluminum bar itself is rigid, and its assembly also needs to match the shape of the vehicle body, and it is necessary to minimize the occupied space and facilitate assembly. At the same time, the safety during high-voltage power transmission must also be taken into account. To meet the above conditions, it is necessary to seek a positive and feasible implementation plan for the application of aluminum bars. Summary of the Utility Model

[0004] Therefore, the main purpose of the utility model is to provide a non-wire power connection assembly that matches the vehicle body. It uses aluminum bars as the power transmission medium, and combines the flattened design with the vehicle body shape matching technology, so that the aluminum bars can closely fit the vehicle body, significantly improving the space utilization rate of the vehicle and the convenience of assembly.

[0005] To achieve the above purpose, the non-wire power connection assembly that matches the vehicle body of the utility model includes: two flattened aluminum bars, the aluminum bars include flat bending sections, vertical bending sections, and torsion bending sections, and an inner isolation layer is provided on the surface of the aluminum bars.

[0006] The aluminum bars are rigid and are shaped through flat bending sections, vertical bending sections, and torsion bending sections to match and closely fit the shape of the vehicle body. Each of the two aluminum bars has an inner isolation layer to isolate each other. The above design not only meets the transmission requirements of the charging power in terms of electrical characteristics, but also can achieve the purpose of lightweight and cost reduction, and at the same time has the advantages of reducing the occupied space and facilitating assembly.

[0012] The following, in conjunction with the drawings and the preferred embodiments of the present utility model, further elaborates the technical means adopted by the present utility model to achieve the intended utility model purpose.

[0013] Please refer to Figure 1 As shown, a non-wire power connection assembly 10 of a preferred embodiment of the present utility model includes two aluminum bars 11, 12. The two aluminum bars 11, 12 can be made of 6101T64 magnesium-silicon aluminum alloy. The two aluminum bars 11, 12 are both long and narrow and flat. The two aluminum bars 11, 12 include flat bending sections 111, 121, vertical bending sections 112, 122, and torsion bending sections 113, 123. The flat bending sections 111, 121 refer to a section of the aluminum bar 11, 12 that is bent in a surface-to-surface direction; the vertical bending sections 112, 122 refer to a section of the aluminum bar 11, 12 that is bent in a direction parallel to the surface; the torsion bending sections 113, 123 refer to a section of the aluminum bar 11, 12 that is twisted by one edge and the other edge in opposite directions. It must be particularly noted that: the two aluminum bars 11, 12 are respectively composed of flat bending sections 111, 121, vertical bending sections 112, 122, and torsion bending sections 113, 123. Among them, the flat bending sections 111, 121, vertical bending sections 112, 122, and torsion bending sections 113, 123 are not limited to one section. That is to say, the two aluminum bars 11, 12 can be respectively composed of one or more flat bending sections 111, 121, one or more vertical bending sections 112, 122, and one or more torsion bending sections 113, 123; in this embodiment, both ends of the two aluminum bars 11, 12 respectively have a vertical bending section 112, 122. One of the vertical bending sections 112, 122 at one end is connected to a torsion bending section 113, 123, and the torsion bending section 113, 123 is connected to the flat bending section 111, 121.

[0014] Furthermore, inner isolation layers 114, 124 are respectively provided on the surfaces of the two aluminum bars 11, 12. The inner isolation layers 114, 124 adopt EMS10991PA12 modified materials, have a high wear resistance level, strong adhesion to the conductor, and have characteristics such as waterproof, resistant to mechanical friction, resistant to bending, and resistant to bumping. Please refer to Figure 2 、 Figure 3As shown in the figure, except for the two ends, the two aluminum bars 11 and 12, which are respectively coated with the inner spacer layers 114 and 124, are overlapped with each other in an insulated manner to reduce the occupied space. The overlapping section of the two aluminum bars 11 and 12 is jointly coated with an outer isolation layer 13 to form an insulated isolation from the vehicle body.

[0015] Since the two aluminum bars 11 and 12 are flat, the waterproof requirement is relatively high after long-term use. Therefore, as Figure 3 shown, in the present utility model, the two side edges of the two aluminum bars 11 and 12 form a full-round R corner, whereby they will fit better with the inner isolation layers 114 and 124 to meet the high-standard waterproof requirement.

[0016] Please refer to Figure 4 shown in the figure, which is a schematic diagram of the use state of the non-wire power connection assembly 10 of the present utility model assembled on a vehicle body 20. The vehicle body 20 particularly refers to the wheel housing part provided with a charging socket 31. One end of the two aluminum bars 11 and 12 of the non-wire power connection assembly 10 is electrically connected to the charging socket 30, and the other end is connected to a high-voltage distribution box 33 through a high-voltage connector 32.

[0017] Please refer to Figure 5 shown in the figure, one end of the two aluminum bars 11 and 12 is connected to the charging socket 31 in an interleaved manner through the transition connection of the torsion bending sections 113 and 123 and the vertical bending sections 112 and 122 from the overlapped state, whereby the space utilization rate at the bottom of the charging socket 31 can be improved.

[0018] Since the two aluminum bars 11 and 12 of the non-wire power connection assembly 10 are composed of the flat bending sections 111 and 121, the vertical bending sections 112 and 122, and the torsion bending sections 113 and 123, through the transition connection of the flat bending sections 111 and 121, the vertical bending sections 112 and 122, and the torsion bending sections 113 and 123, the non-wire power connection assembly 10 can be fully routed in accordance with the shape of the vehicle body 20. Due to the above design, the non-wire power connection assembly 10 can be matched and as close as possible to the vehicle body 20. Considering the vibration of the non-wire power connection assembly 10 caused by the wheel running, the distance between the non-wire power connection assembly 10 and the vehicle body 20 must be greater than or equal to 3 mm.

[0019] Please refer to Figure 4As shown, the non-wire power connection assembly 10 only needs to use a few fixing brackets to firmly mount the non-wire power connection assembly 10 on the vehicle body 20. In this embodiment, three fixing brackets 40 are used. One fixing bracket 40 is located at one end of the non-wire power connection assembly 10 close to the charging socket 30, and another fixing bracket 40 is located in the middle section of the non-wire power connection assembly 10. The fixing bracket 40 includes a coupling portion 41 and a fixing portion 42. The coupling portion 41 has an opening for accommodating the non-wire power connection assembly 10 therein, and fixing holes are formed on the fixing portion 42 for fixing to the vehicle body 20. A fixing bracket 40 is also provided at the other end of the non-wire power connection assembly 10 adjacent to the high-voltage connector 32. Since it is adjacent to the high-voltage end, the coupling portion of the fixing bracket 40 provided at this end is coated with a rubber layer to enhance the insulation and isolation effect.

[0020] As can be seen from the above, the present utility model uses a rigid aluminum row as the charging wire routing for new energy vehicles. The two aluminum rows are transitionally connected through flat bending sections, vertical bending sections, and torsion bending sections to match and be as close as possible to the vehicle body. This design not only meets the transmission requirements of the charging power in terms of electrical characteristics, but also achieves the purpose of lightweight and cost reduction, and at the same time has the advantages of reducing the occupied space and facilitating assembly.

[0021] The above are only the preferred embodiments of the present utility model and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
