The battery 9 is electrically connected to the linear brake 5. In the preferred embodiment, the linear brake 5 is a pressure operated power cylinder, which may be a pneumatic or hydraulic cylinder.In the preferred exemplary embodiment, the two ends of the two linkage arrangements 6 are each connected between the front structure 1 and the rear structure 2, wherein the respective linkage arrangement 6 forms a pedal of the electric motor. The linkage assembly 6 includes a front connecting rod 61, a rear connecting rod 62, a first upper connecting rod 63, a second upper connecting rod 64, a lower connecting rod 65, a base 66, a rear support arm 67, a lower tie rod 68, and an upper tie rod 69.As shown in FIG. 3, the front connecting rod 61 is vertically disposed on the front body, and the rear connecting rod 62 is vertically disposed between the front connecting rod 61 and the rear body 2. The first upper connecting rod 63 is horizontally disposed between the rear connecting rod 62 and the front connecting rod 61, and the rear end 632 of the first upper connecting rod 63 is rotatably supported at the upper end 621 of the rear connecting rod 62. The second upper connecting rod 64 is horizontally disposed between the first upper connecting rod 63 and the front connecting rod 61, the rear end 642 of the second upper connecting rod 64 is rotatably supported at the front end 631 of the first upper connecting rod 63, and the front end 641 of the second upper connecting rod 64 is rotatably supported at the upper end 611 of the front connecting rod 61. The lower connecting rod 65 is horizontally disposed between the rear connecting rod 62 and the front connecting rod 61 and is located below the first upper connecting rod 63 and the second upper connecting rod 64, the rear end 652 of the lower connecting rod 65 is rotatably supported at the lower end 622 of the rear connecting rod 62, and the front end 651 thereof is rotatably supported at the lower end 612 of the front connecting rod 61. The front end 511 of the push rod 51 of the linear brake 5 is rotatably supported on the upper end 621 of the rear connecting rod 62.The base 66 is disposed between the front connecting rod 61 and the rear body 2, and the lower end 622 of the rear connecting rod 62 and the rear end 652 of the lower connecting rod 65 are rotatably supported at the lower end 661 of the base 66.The rear support arm 67 is horizontally disposed between the rear structure 2 and the base 66, the rear end 672 of the rear support arm 67 being fixed to the rear structure 2, the base 66 being fixed to the front end 671 of the inner support arm 67. Further, a lifting profile 673 is arranged on the rear support arm 67.As shown in FIGS. 3 and 4, the rear end 682 of the lower tie rod 68 is slidably disposed in the stroke profile 673, and the front end 681 thereof is rotatably supported on the rear end 642 of the second upper connecting rod 64. The upper end 691 of the upper tie rod 69 is rotatably supported on the support assembly 7 and the lower end 692 thereof is rotatably supported on the rear end 682 of the lower tie rod 68.In a possible embodiment, a plurality of support arrangements 7 are provided, which are arranged on both sides of the rear structure 2, respectively. The respective support assembly 7 includes a link 71, a front support 72, and a rear support 73.As shown in FIG. 3, the front end 711 of the link 71 is rotatably supported on the front end 71 of the lower part of the seat 4. The front bracket 72 is rotatably supported between the front end 21 of the rear body 2 and the front end 711 of the link 71, and the upper end 691 of the upper tie rod 69 is rotatably supported in the central portion of the front bracket 72. The rear support 73 is rotatably supported between the rear end 22 of the rear structure 2 and the rear end 712 of the link 71, the front support 72 and the rear support 73 being parallel to each other.As shown in FIGS. 3 to 6, in use of the electric automobile, the battery 9 supplies power to the linear brake 5 so that the push rod 51 of the linear brake 5 drives the upper end 621 of the rear connecting rod 62 so that the push rod 51 of the linear brake 5 swings the upper end 621 of the rear connecting rod 62 toward the front body 1 (see FIGS. 3 and 4 ) to drive the first upper connecting rod rod 63 eand the second upper connecting rod 64 to push the upper end 611 of the front connecting rod 61. By the second upper connecting rod 64 increasing the angle of folding, the lower end 612 of the front connecting rod 61 makes the lower connecting rod 65 push the lower end 622 of the rear connecting rod 62 toward the rear end 2 (see FIGS. 5 and 6 ) to swing the rear end 642 of the second upper connecting rod 64 and the rear end 652 of the lower connecting rod 65 upward, so that the front end 1 is folded toward and along with the rear end 2.At the same time, the push rod 51 of the linear brake 5 drives the rear end 682 of the lower pull rod 68 via the rear end 642 of the second upper connecting rod 64 such that the rear end 682 of the lower pull rod 68 slides in the lifting profile 673 in the direction of the front structure 1. This causes the upper tie rod 69 to swing the support assembly 7, the front support 72 and the seat 4 toward the front structure 1, thereby folding the back structure 2 toward and with the front structure 1. During this, the lower end 622 of the rear connecting rod 62 and the lower end 612 of the front connecting rod 61 may serve as auxiliary support points for collapsing the linkage assembly 6 to pivot the front connecting rod 61, the first upper connecting rod 63, the second upper connecting rod 64, and the rear support arm 67 upwardly and thus collapse.As can be seen from the above-mentioned designations, the linkage arrangement 6 forms a pedal of the electric motor vehicle according to the invention. By means of the linkage arrangement 6, the front structure 1 and the rear structure 2 can be folded upwards and folded together, so that the upper space of the electric motor vehicle is filled with the linkage arrangement 6 and the seat 4. In this way, the electric motor vehicle can be folded together easily, easily and quickly. In the folded state, the distance between the front structure 1 and the rear structure 2 is reduced, so that the overall length of the electric motor vehicle is adjusted in order to reduce the required area and the space connected thereto for parking the folded electric motor vehicle. Furthermore, the front wheel 11 and the rear wheels 23 of the folded electric motor vehicle remain in horizontal contact with the ground, so that the user grasps the handlebar 3 and thus pulls the electric motor vehicle comfortably. This position can also prevent tilting of the electric motor vehicle. Further, when folding the electric automobile with the rear body 2 and the rear support arm 67, the battery 9 is pivoted toward the rear side of the electric automobile, and the seat 4 is automatically folded up, so that the user can easily take out and change the battery 9. Thus, the taken-out battery 9 can be brought to a charging place for charging and protected from theft.When the push rod 51 of the linear brake 5 counter-swings the upper end 621 of the rear connecting rod 62 toward the rear 2, the rear connecting rod 62 will move the first upper connecting rod 63, the second upper connecting rod 64, the front connecting rod 61, the lower connecting rod 65, the rear support arm 67, the lower pull rod 68, the upper pull rod 69, and the support assembly 7 and thereby bring them to the respective original position. Once the upper connecting rod 63, the second upper connecting rod 64, and the rear support arm 67 are in the horizontal position, the electric motor vehicle can be inserted.For a further possible embodiment, reference is made to FIGS. 2 and 3. It is conceivable to additionally arrange a guide channel 24 on the lower part of the rear structure 2, which guide channel extends in the direction of the front structure 1. The linear brake 5 is slidably disposed in the guide groove 24. At the rear end 52 of the linear brake 5, a positioning hole 53 is disposed. On the lower part of the rear structure 2, a lever 25 is rotatably supported, on which a fixing pin 26 is disposed, the fixing pin 26 being inserted into the positioning hole 53 at the rear end 52 of the linear brake 5 to fix the linear brake 5 to the rear part of the rear structure 2.It can also be seen from FIG. 7 that, when the electric motor vehicle is unfolded, the user can manually fold over the lever 25 if the battery 9 does not have any current or the linear brake 5 is defective. The lever 25 makes the fixing pin 26 to disengage from the positioning hole 53 at the rear end 52 of the linear brake 5 to release the linear brake 5, so that the linear brake 5 can freely slide in the guide groove 24. In this way, the user can manually fold up the linkage arrangement 6 such that the push rod 51 of the linear brake 5 is thereby caused to move by the linkage arrangement 6, such that the linear brake 5 is displaced in the guide channel 24 in the direction of the front structure 1. The electric motor vehicle is thus folded together manually.Moreover, it is possible to arrange the front wheel 11 in the form of an independent suspension structure at the lower part of the front body 1 and the rear wheels 23 also in the form of an independent suspension structure at the lower part of the rear body 2. This increases the damping of the electric motor vehicle.Although the present invention has been described in detail with reference to an exemplary embodiment, it is obvious to a person skilled in the art that the invention is not limited to this exemplary embodiment, but rather that modifications are possible in such a way that individual features can be omitted or other combinations of features can be realized, as long as the scope of protection of the appended claims is not left. The disclosure of the present invention includes all combinations of the individual features presented.List of reference characters1 Front body 11 Front wheel 2 Rear body 21 Front end 22 Rear end 23 Rear wheel 24 Guide groove 25 Lever 26 Fixing pin 3 Steering rod 4 Seat 41 Front end 5 Linear brake 51 Push rod 511 Front end 52 Rear end 53 Positioning hole 6 Link assembly 61 Front connecting rod 611 Upper end 612 Lower end 62 Rear connecting rod 621 Upper end 622 Lower end 63 First upper connecting rod 631 Front end 632 Rear end 64 Second upper connecting rod 641 Front end 642 Rear end 65 Lower connecting rod 651 Front end 652 Rear end 66 Base 661 Lower end 67 Rear support arm 671 Front end 672 Rear end 673 Stroke profile 68 Lower pull rod 681 Front end 682 Rear end 69 Upper pull rod 691 Upper end 692 Lower end 7 Support assembly 71 Link 711 Front end 712 Rear end 72 front bracket 73 rear bracket 8 motor 9 battery
