In order to make the electric vehicle beautiful as a whole, a plate-shaped decorative plate is provided on the outside of the frame, and the decorative plate makes the electric vehicle round as a whole. The decorative plate is usually made of plastic material, such as PP, ABS, ASA, POM, PA, PC, PE and other materials. The outer peripheral surface of the existing electric vehicle is basically fully covered with plastic decorative plates. Electric vehicles covered with all plastic will have problems such as low support strength, poor anti-collision effect and short service life during use.

[0003] A Chinese patent document (authorization announcement number: CN 204452631U) discloses an aluminum alloy body frame of an electric vehicle and an electric vehicle, wherein the aluminum alloy body frame includes a roof frame, a side frame, and a reinforcing beam; wherein the side frame includes a plurality of side columns extending in the vertical direction, and the roof frame includes a roof cross beam; wherein the side columns and the roof cross beam are both fixedly assembled on the reinforcing beam; wherein a window is provided on the side frame, and the window includes a side window upper longitudinal beam and a side window lower longitudinal beam fixed on the side column; and a waist reinforcing beam is also provided in the middle of the side frame. Its structure is more reasonable and can enhance the structural strength of the frame.

[0004] This type of electric vehicle uses an aluminum alloy frame, and its periphery still needs to be covered with plastic decorative panels to make the electric vehicle appear perfectly presented as a whole. However, electric vehicles covered entirely with plastic will also bring the above-mentioned technical problems during use. Summary of the invention

[0005] The technical problem to be solved by the present invention is: to provide an electric vehicle with a metal shell, which can effectively reduce the proportion of vehicle-mounted plastic parts in the entire vehicle and effectively improve the anti-collision effect and service life of the electric vehicle during use.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: an electric vehicle with a metal shell, comprising a frame, the frame comprising a faucet pipe arranged at the front end, and a sunken pedal portion formed at the middle position of the frame, characterized in that it includes: A connecting seat, the connecting seat is supported by the faucet pipe; The front enclosure is located above and obliquely behind the front wheel of the electric vehicle, and includes a front enclosure plate, the front enclosure plate has two lower extensions arranged in parallel and extending downward, the outer surfaces of the lower extensions mainly constitute the side surfaces of the front enclosure, the upper sides of the two lower extensions are connected together by a connecting portion, and the connecting portion is connected to the connecting seat; The side strips are two plate-shaped bodies, which are respectively arranged on opposite sides of the width direction of the pedal part, the outer surface of the side strips is exposed, and the length of the side strips is at least equal to the length of the pedal part; A seat cushion support portion, used to support the seat cushion, comprising side panels arranged on two opposite sides, wherein the outer surfaces of the side panels mainly constitute the side surfaces of the seat cushion support portion; The front panel, side strips and side panels are made of metal.

[0007] The metal material can be aluminum alloy, stainless steel or iron sheet, but aluminum alloy is generally preferred. These metal parts are made into plate-shaped bodies, and their outer surfaces serve as the main part of the overall outer surface of the electric vehicle. The side strips generally cannot cover all sides of the pedal part of the electric vehicle, and a part of plastic parts needs to be set on the lower side of the side strips to adapt to the arc coverage.

[0008] Furthermore, it also includes a cylindrical upper protective tube, which is also made of metal, and the lower end of the upper protective tube is connected to the connection seat, and the upper protective tube is wrapped around the outer periphery of the lower part of the faucet of the electric vehicle, and the outer peripheral surface of the upper protective tube is exposed. The upper side of the front enclosure and the lower part of the faucet are covered by the upper protective tube, which can well meet the full covering decoration requirements of the electric vehicle.

[0009] Furthermore, the upper protective tube is formed by buckling two arc-shaped monomers together, which facilitates the installation and removal of the upper protective tube and can effectively reduce the parts that need to be removed when repairing the lower part of the faucet.

[0010] Furthermore, a connection groove and a connection convex body are respectively provided at the buckle joint positions of the two monomers, and the connection convex body is inserted into the connection groove in a matching manner. The two monomers can be assembled and disassembled in a straight-insertion manner, and the operation is very convenient.

[0011] Furthermore, the monomer, the front panel, the side strips and the side panels are all extruded parts, and the direction of their outer surfaces is the same as their respective extrusion directions during the molding process; a number of connecting strips are formed on their inner surfaces, and the connecting strips extend along their respective extrusion directions during the molding process. After molding, these metal parts only need to be directly cut into the required size, and no subsequent bending process is performed to adapt to the arc surface coverage of the electric vehicle, which can effectively improve the working efficiency. The arc surface coverage of the electric vehicle can be compensated by setting some plastic parts.

[0012] Furthermore, the upper end of the upper protective tube, the front and rear ends of the front panel, and the front and rear ends of the two side panels are respectively provided with sealing pieces, which are fixed by screws connected to the ends of the corresponding connecting strips. These sealing pieces are generally made of plastic, rubber or other non-metallic materials, so that a relatively closed space can be formed inside these metal parts, which can effectively protect the safety of some wire connectors on the electric vehicle.

[0013] Furthermore, the front panel includes an inverted L-shaped left panel and a right panel, the left panel and the right panel are symmetrically arranged, and the upper parts of the left panel and the right panel are connected together to form the connecting part. This facilitates the preparation of the front panel and makes the preparation of the front panel efficient.

[0014] Furthermore, the connection seat is annular, the connection seat is sleeved on the outer periphery of the faucet pipe, a protruding connection frame is fixedly connected to the faucet pipe, and the connection seat is connected to the connection frame. By providing the annular connection seat, it can well adapt to the setting of the cylindrical upper casing, and conveniently provide stable connection support for the upper casing.

[0015] Furthermore, the connection seat is supported on the fixing block, which is arc-shaped. The fixing block is fixedly connected to the faucet pipe through the connection frame. An arc-shaped cushion block is provided at the position corresponding to the fixing block on the outside of the connection seat, and the outer side of the cushion block is adapted to be covered with an exterior panel. The connection seat is supported by the setting of the fixing block; the cushion block is provided to adapt to the inclined setting of the upper casing relative to the connection seat, and the gap generated by the inclined setting of the upper casing can be effectively filled to achieve stable support for the upper casing; the exterior panel is provided to play a decorative and sealing role.

[0016] Furthermore, the lower end of the lower extension of the front panel is connected to the front end of the corresponding side strip, and the rear end of the connecting strip is connected to the lower end of the corresponding side panel. Combined with the setting of the connecting seat, the upper protective tube, the front panel, the side strip and the side panel can be connected as a whole, so that these components support each other in strength, thereby forming a stable external protection system on the electric vehicle, which can effectively improve the anti-collision performance of the electric vehicle and the overall strength of the electric vehicle is high.

[0017] Compared with the prior art, the present invention has the beneficial effect that the metal parts are arranged on the electric vehicle, thereby effectively reducing the use of plastic exterior parts of the electric vehicle as a whole, and effectively reducing the proportion of plastic parts in the electric vehicle as a whole. The use of these metal parts makes the overall appearance of the electric vehicle present a metallic texture, which can be distinguished from the shape of ordinary electric vehicles. The metal parts play a decorative role in the appearance of the electric vehicle. Compared with plastic parts, metal parts are more resistant to external corrosion and have a long-lasting effect. The use of metal parts can effectively improve the overall strength of the electric vehicle. When it is subjected to external impact, it is usually only manifested in deformation, and it is not easy to be broken and need to be replaced in time. BRIEF DESCRIPTION OF THE DRAWINGS

The front enclosure plate 41 has two downward-extending parts 411 arranged in parallel, and the upper sides of the two downward-extending parts 411 are connected together through a connecting part 412. The front enclosure plate 41 shown in the figure is in a "冂" shape, but it does not exclude that the lower ends of the two downward-extending parts 411 on the front enclosure plate 41 are flared outward. The connecting part 412 is generally connected to the connecting seat 11 through connecting bolts, and the connecting part 412 can also be fixed to the connecting seat 11 through other intermediate transition parts. Figure 1 As shown, the front enclosure plate 41 wraps around the outside of the front enclosure part 4, the outer surface of the downward-extending part 411 is exposed, the outer surface of the downward-extending part 411 mainly constitutes the side surface of the front enclosure part 4, and the upper surface of the connecting part 412 mainly constitutes the top surface of the front enclosure part 4.

[0028] On the opposite sides in the width direction of the pedal part 6, two side strips 5 made of aluminum alloy are respectively arranged. The side strips 5 are plate-shaped bodies, the outer surfaces of the side strips 5 are exposed, the side strips 5 constitute a part of the side of the pedal part 6, and the length of the side strips 5 is at least equal to the length of the pedal part 6.
