[0035] The embodiments of this utility model are described in detail below, with examples of the embodiments shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1 to 9 As shown, the electric vehicle seat 100 of this embodiment includes a frame 1, a foam layer 2, and a covering layer 3. The frame 1 includes a metal plate 11 and an annular plastic frame 12, which surrounds the edge of the metal plate 11 and is connected to it. The covering layer 3 covers the outside of the frame 1 and is connected to the plastic frame 12. The foam layer 2 is fixed between the frame 1 and the covering layer 3.

[0037] Among them, the foam layer 2 can be a sponge layer, and the covering layer 3 can be a leather layer, which covers and fixes the sponge layer and the skeleton 1.

[0038] The electric vehicle seat 100 of this embodiment of the utility model forms a frame 1 by connecting a metal plate 11 and a plastic frame 12, so that the material of the frame 1 includes not only plastic but also metal, thereby reducing the proportion of flammable materials in the frame 1. By setting the plastic frame 12 around the edge of the metal plate 1, the covering layer 3 can be connected to the plastic frame 12, and the foam layer 2 is covered and fixed between the frame 1 and the covering layer 3. As a result, the proportion of flammable materials in the electric vehicle seat 100 can be reduced, improving the fire resistance and flame retardant performance of the electric vehicle and enhancing its safety.

[0039] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 As shown, the metal plate 11 is provided with a reinforcing structure 111.

[0040] By providing a reinforcing structure 111 on the metal plate 11, the structural strength of the reinforcing plate 11 can be improved, thereby improving the structural strength of the frame 1 and the structural strength of the electric vehicle seat 100.

[0041] Optionally, the reinforcing structure 111 includes protrusions and / or recesses provided on the metal plate 11.

[0042] The protrusion can be formed by stamping a portion of the metal plate 11, and the recess can be formed by stamping a portion of the metal plate 11.

[0043] By making the reinforcing structure 111 a protrusion and / or a recess, the structure of the frame 1 can be simplified, making it easier to process and manufacture the electric vehicle seat 100.

[0044] Of course, in other embodiments, reinforcing ribs may also be provided on the metal plate 11, forming a reinforcing structure 111.

[0045] To make the technical solution of this utility model easier to understand, the following description further illustrates the technical solution of this utility model, taking the example that the height direction of the electric vehicle seat 100 is consistent with the vertical direction. Wherein, the vertical direction is as follows... Figure 1 , Figures 3 to 5 , Figures 7 to 9 As shown.

[0046] For example, a foam layer 2 is disposed on the upper side of the skeleton 1, and a covering layer 3 is disposed on the upper side of the foam layer 2. A portion of the metal plate 11 is pressed downward to form a recess, which forms a reinforcing structure 111.

[0047] Optionally, the metal plate 11 is a sheet metal part, which is integrally stamped.

[0048] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the metal plate 11 is provided with a first flange 114, and the plastic frame 12 is connected to the first flange 114.

[0049] For example, the first flange 114 is annular, the first flange 114 is provided corresponding to the plastic frame 12, and the first flange 114 and the plastic frame 12 are stacked and connected.

[0050] By setting the first flange 114, it is beneficial to increase the connection area between the plastic frame 12 and the metal plate 11, improve the reliability of the frame 1, and thus improve the reliability of the electric vehicle seat 100.

[0051] In some embodiments, the plastic frame 12 is provided with a second flange 125, and the covering layer 3 is connected to the second flange 125.

[0052] For example, the second flange 125 is annular, and a portion of the covering layer 3 wraps around and connects to the second flange 125. The covering layer 3 and the second flange 125 can be connected by rivets.

[0053] By setting the second flange 125, it is convenient to connect the covering layer 3 to the plastic frame 12, which helps to improve the assembly efficiency of the electric vehicle seat 100.

[0054] In some embodiments, the metal plate 11 and the plastic frame 12 are integrally injection molded.

[0055] For example, the plastic frame 12 is fixed to the edge of the metal plate 11, so that the edge of the metal plate 11 is covered by a plastic frame.

[0056] By integrally injection molding the metal plate 11 and the plastic frame 12, it is convenient to connect the metal plate 11 and the plastic frame 12, and to facilitate the processing and manufacturing of the skeleton 1.

[0057] Optionally, such as Figure 4 As shown, the metal plate 11 is provided with an injection hole 112, and the plastic frame 12 is provided with an embedding part 121, which is embedded in the injection hole 112.

[0058] For example, the first flange 114 is provided with an injection hole 112, and the plastic frame 12 is connected to the first flange 114. When the plastic frame 12 and the metal plate 11 are integrally injection molded, a portion of the injection molding material flows into the injection hole, and this portion of the injection molding material solidifies to form the insert 121.

[0059] By providing injection holes 112 in the metal plate 11 and embedding the insert portion 121 of the plastic frame 12 in the injection holes 112, the bonding force between the metal plate 11 and the plastic frame 12 can be improved, the connection reliability between the metal plate 11 and the plastic frame 12 can be improved, and the reliability of the electric vehicle seat 100 can be improved.

[0060] Optionally, there may be multiple injection holes 112, which are spaced apart around the edge of the metal plate 11.

[0061] By setting multiple injection holes 112, the bonding force between the metal plate 11 and the plastic frame 12 can be further improved, thereby enhancing the reliability of the electric vehicle seat 100.

[0062] Optionally, such as Figure 4 As shown, the plastic frame 12 includes a first injection molding layer 122 and a second injection molding layer 123 arranged at intervals, and a portion of the metal plate 11 is embedded between the first injection molding layer 122 and the second injection molding layer 123.

[0063] For example, the first injection layer 122 is disposed on the upper side of the second injection layer 123, and the first flange 114 is embedded between the first injection layer 122 and the second injection layer 123.

[0064] By embedding a portion of the metal plate 11 between the first injection molding layer 122 and the second injection molding layer 123, the connection area between the metal plate 11 and the plastic frame 12 can be increased, the connection reliability between the metal plate 11 and the plastic frame 12 can be improved, and the reliability of the electric vehicle seat 100 can be improved.

[0065] In some embodiments, such as Figure 5 and Figure 6 As shown, the electric vehicle seat 100 also includes a fastener 4, and the metal plate 11 and the plastic frame 12 are connected by the fastener 4.

[0066] For example, the first flange 114 is connected to the plastic frame 12 by a fastener 4. The fastener 4 can be a bolt, screw, or self-tapping screw, etc.

[0067] The metal plate 11 and the plastic frame 12 are connected by fasteners 4. The metal plate 11 and the plastic frame 12 can be processed and manufactured separately first, and then the metal plate 11 and the plastic frame 12 can be connected and fixed. This allows the processing and manufacturing of the metal plate 11 and the plastic frame 12 to be independent of each other, which facilitates the processing and manufacturing of the frame 1.

[0068] Optionally, such as Figure 5 As shown, fastener 4 extends along the height direction of electric vehicle seat 100.

[0069] For example, the metal plate 11 has a first connecting hole, the plastic frame 12 has a second connecting hole, and the fastener 4 passes through the first connecting hole and is connected to the second connecting hole. Both the first and second connecting holes extend vertically, and the fastener 4 extends vertically as well.

[0070] Understandably, to ensure the structural strength of the connection between the metal plate 11 and the plastic frame 12, the cross-sectional area of ​​the metal plate 11 and the plastic frame 12 in the direction perpendicular to the height of the electric vehicle seat 100 should be relatively large to prevent cracking of the metal plate 11 and the plastic frame 12 after the fastener 4 passes through. To ensure the load-bearing area of ​​the electric vehicle seat 100, the cross-sectional area of ​​the metal plate 11 and the plastic frame 12 in the direction perpendicular to the height of the electric vehicle seat 100 is typically set to be relatively large.

[0071] Therefore, by setting the fastener 4 to extend along the height direction of the electric vehicle seat 100, the connection strength of the metal plate 11 and the plastic frame 12 can be guaranteed without increasing the other dimensions of the metal plate 11 and the plastic frame 12, which is beneficial to improving the reliability of the electric vehicle seat 100.

[0072] In some embodiments, the plastic frame 12 is thermally fused to the metal plate 11.

[0073] By hot-melting the plastic frame 12 to the metal plate 11, the reliability of the connection between the plastic frame 12 and the metal plate 11 is improved, thereby improving the reliability of the electric vehicle seat 100.

[0074] Optionally, such as Figure 9 As shown, the plastic frame 12 is provided with a hot-melt column 124, and the metal plate 11 is provided with a fixing hole 113. The hot-melt column 124 is inserted and fixed in the fixing hole 113.

[0075] For example, such as Figure 9 As shown, after the hot melt column 124 is inserted into the fixing hole 113, the hot riveting gun 200 or the ultrasonic welding gun heats the hot melt column 124, causing the hot melt column 124 to melt and deform. After the hot melt column 124 cools down, it forms a limiting protrusion, which clamps the metal plate 11 between the plastic frame 12 and the limiting protrusion, thereby achieving the connection and fixation between the metal plate 11 and the plastic frame 12.

[0076] By setting hot-melt pillars 124 in the plastic frame 12 and fixing holes 113 in the metal plate 11, the hot-melt pillars 124 are inserted and fixed in the fixing holes 113, which facilitates the hot-melt connection between the plastic frame 12 and the metal plate 11 and helps to improve the assembly efficiency of the electric vehicle seat 100.

[0077] Optionally, the hot-melt column 124 and the fixing hole 113 both extend along the height direction of the electric vehicle seat 100.

[0078] Understandably, to ensure the structural strength of the connection between the metal plate 11 and the plastic frame 12, the cross-sectional area of ​​the metal plate 11 in the direction perpendicular to the height of the electric vehicle seat 100 should be relatively large to avoid cracking at the fixing hole 113. To ensure the load-bearing area of ​​the electric vehicle seat 100, the cross-sectional area of ​​the metal plate 11 in the direction perpendicular to the height of the electric vehicle seat 100 is typically set relatively large.

[0079] Therefore, by setting the hot melt column 124 and the fixing hole 113 to extend along the height direction of the electric vehicle seat 100, the connection strength between the metal plate 11 and the plastic frame 12 can be guaranteed without increasing other dimensions of the metal plate 11, thereby improving the reliability of the electric vehicle seat 100.

[0080] The electric vehicle of this utility model embodiment includes the electric vehicle seat 100 described in any of the above embodiments. The electric vehicle can be an electric bicycle or an electric tricycle, etc.

[0081] In this embodiment of the electric vehicle, by designing the frame 1 of the electric vehicle seat 100 to include a metal plate 11 and a plastic frame 12, the proportion of plastic material in the electric vehicle seat 100 can be reduced. For example, the proportion of plastic material in the electric vehicle seat 100 can be reduced by 60% to 70%, that is, the proportion of flammable material in the electric vehicle seat 100 can be reduced by 60% to 70%. This improves the fire resistance and flame retardancy of the electric vehicle and enhances its safety performance.
