[0024] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] It is understandable that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular or equal to each other. For example, combined with numerical description, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0028] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel. For example, in numerical terms, parallel can refer to the angle between two straight lines within the range of 180° ± 10°, the dihedral angle between two planes within the range of 180° ± 10°, or the angle between a straight line and a plane within the range of 180° ± 10°. The two components described as "parallel" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is straight or plane, the component can be considered a "straight line" or "plane".

[0029] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please refer to the following: Figure 1 and Figure 2The electric motorcycle 100 includes a frame 11, a body panel 12, a motor 200, a power battery 13, an electronic control system (not shown), a running system 15, and a suspension assembly 16. The frame 11 forms the basic framework of the electric motorcycle 100 and supports other components. The body panel 12 is at least partially mounted on the frame 11 and protects the internal parts of the electric motorcycle 100. The power battery 13 supplies power to the motor 200. The electronic control system includes a motor control assembly 14, which is electrically connected to the motor 200 and primarily controls the motor 200. The running system 15 is connected to the motor 200 and receives driving force from the motor 200 to propel the electric motorcycle 100. The running gear system 15 includes a front running wheel 151 located at the front of the electric motorcycle 100 and a rear running wheel 152 located at the rear of the electric motorcycle 100. At least a portion of the front running wheel 151 and at least a portion of the rear running wheel 152 are located below the frame 11, and the front running wheel 151 and the rear running wheel 152 are rotatably connected to the front and rear ends of the frame 11, respectively. The suspension system 16 includes a front suspension assembly 161 and a rear suspension assembly 162. The front suspension assembly 161 connects the front running wheel 151 to the frame 11, and the rear suspension assembly 162 connects the rear running wheel 152 to the frame 11.

[0032] For ease of expression, the definitions in this application are as follows: Figure 3 The directions shown are front, back, left, right, up, and down. The front-back direction refers to the length of the frame 11 of the electric motorcycle 100, the left-right direction refers to the width of the frame 11, and the up-down direction refers to the height of the frame 11. In this embodiment, the front, back, left, right, up, and down directions are based on the electric motorcycle 100 traveling on a level road surface, not on a sloping road surface.

[0033] Please see Figure 2 In one implementation, the frame 11 includes an upper crossbeam 111 and a lower crossbeam 112. Both the upper crossbeam 111 and the lower crossbeam 112 can be optionally composed of support tubes distributed on the left and right sides of the electric motorcycle 100. A horizontal tube is also provided between the left and right support tubes to achieve a fixed connection between the left and right support tubes. Observing the frame 11 in the left-right direction, a receiving space 101 is formed between the upper crossbeam 111 and the lower crossbeam 112. The power battery 13 is installed in the receiving space 101. The power battery 13 includes an upper end face 131 and a lower end face 132. The upper end face 131 is connected to the upper crossbeam 111, and the lower end face 132 is connected to the lower crossbeam 112.

[0034] The frame 11 also includes a vertical connecting section 118, which is located behind the power battery 13 and connects between the upper crossbeam 111 and the lower crossbeam 112. The vertical connecting section 118 can be composed of support tubes distributed on the left and right sides of the electric motorcycle 100, and a horizontal tube is also provided between the left and right support tubes to achieve a fixed connection between the left and right support tubes.

[0035] Please see Figure 4 The vehicle body panel 12 includes a seat 121, which is mounted on top of the frame 11 for the driver to sit on. The connection between the frame 11 and the seat 121 forms a mounting space 102 below the seat 121. A power connector 133 is located on the top of the power battery 13, on its upper surface 131, and is electrically connected to the motor control assembly 14 via a wiring harness. The mounting space 102 communicates with the receiving space 101, and the power connector 133 extends into the mounting space 102. The electric motorcycle 100 also includes an electrical system 18, which includes a fuse box 181, a relay 182, and an on-board diagnostic interface 183, all located within the mounting space 102. By placing the power connector 133, fuse box 181, relay 182 and vehicle automatic diagnostic interface 183 in the installation space 102, the power connector 133, fuse box 181 and relay 182 can be disassembled and maintained simply by removing the seat 121, which facilitates the later maintenance of the electric motorcycle 100.

[0036] The frame 11 also includes a rear connecting section 117, which can be composed of support tubes distributed on the left and right sides of the electric motorcycle 100. A cross tube is also provided between the left and right support tubes to achieve a fixed connection between the left and right support tubes. The rear connecting section 117 is connected to the rear end of the upper crossbeam 111 and is located above the rear wheel 152. The seat 121 connects the upper crossbeam 111 and the rear connecting section 117. The mounting space 102 includes a front space 1021 and a rear space 1022. The front space 1021 is located below the part of the seat 121 that connects to the upper crossbeam 111, and the rear space 1022 is located below the part of the seat 121 that connects to the rear connecting section 117. The power connector 133 is located in the front space 1021, while the fuse box 181, relay 182 and on-board automatic diagnostic interface 183 are located in the rear space 1022, so as to isolate the power connector 133 from other electrical devices and improve the safety performance of the electric motorcycle 100.

[0037] The vertical connecting section 118 includes a first connecting segment 1181 and a second connecting segment 1182. One end of the first connecting segment 1181 is connected to the junction of the upper crossbeam 111 and the rear connecting section 117, and the other end is connected to the rear end of the lower crossbeam 112. One end of the second connecting segment 1182 is connected to the upper part of the first connecting segment 1181, and the other end is connected to the rear end of the rear connecting section 117. The end of the second connecting segment 1182 connected to the first connecting segment 1181 is lower than the end of the rear connecting section 117 connected to the first connecting segment 1181. This arrangement improves the strength of the frame 11, especially the spatial stability of the rear space 1022. In one implementation, viewed from left to right, the area enclosed by the second connecting segment 1182, the first connecting segment 1181, and the rear connecting segment 117 overlaps with at least a portion of the rear space 1022. Specifically, the area enclosed by these three segments can be entirely within the rear space 1022, or the main body of the area enclosed by these three segments can be within the rear space 1022. This main body refers to the portion used to house the various electrical components. A mounting base (not shown) can also be installed within the rear space 1022. The mounting base is used to fix the components to the second connecting segment 1182 and to support the electrical components within the rear space 1022. This arrangement provides lateral protection for the fuse box 181, relay 182, and on-board diagnostic interface 183, provides a mounting base for these components, and protects them from debris and mud below the mounting base moving upwards and affecting them. In one specific implementation, the end of the second connecting segment 1182 that is away from the first connecting segment 1181 bends backward and upward to avoid the rear travel wheel 152.

[0038] Please refer to the following: Figure 4 and Figure 5 In one implementation, the seat 121 includes a seat body 1211 and an upper connecting assembly 1212 connected to the lower part of the seat body 1211. The frame 11 includes a lower connecting assembly 119, which is connected to the upper connecting assembly 1212 to improve the stability of the connection between the seat 121 and the frame 11 and to facilitate the removal of the seat 121.

[0039] The upper connecting assembly 1212 includes a first upper connecting member 1212A, a second upper connecting member 1212B, and a third upper connecting member 1212C arranged sequentially from front to back on the seat body 1211. The lower connecting assembly 119 includes a first lower connecting member 1191, a second lower connecting member 1192, and a third lower connecting member 1193. The first lower connecting member 1191 is fixedly connected to the front end of the upper crossbeam 111, the second lower connecting member 1192 is fixedly connected to the rear end of the upper crossbeam 111, and the third lower connecting member 1193 is fixedly connected to the rear end of the rear connecting section 117. The first upper connecting member 1212A is correspondingly connected to the first lower connecting member 1191, the second upper connecting member 1212B is correspondingly connected to the second lower connecting member 1192, and the third upper connecting member 1212C is correspondingly connected to the third lower connecting member 1193, thereby increasing the connection points between the seat 121 and the frame 11 and improving the stability of the connection between the seat 121 and the frame 11.

[0040] The first upper connector 1212A has a latch 1212D and abutments 1212E arranged on both sides of the latch 1212D in the left-right direction. The front side of the latch 1212D has an opening. The first lower connector 1191 has a front sheet metal 1191A and a latch 1191B fixed to the front sheet metal 1191A. The thickness direction of the front sheet metal 1191A is basically perpendicular to the extension direction of the upper crossbeam 111. The end of the latch 1191B away from the front sheet metal 1191A is bent backward and upward relative to the front sheet metal 1191A. The latch 1191B extends into the opening on the front side of the latch 1212D and engages with the latch 1212D. The abutments 1212E abut downward against the front sheet metal 1191A to stably fix the front end of the seat cushion 121 to the frame 11. In one specific implementation, the abutment 1212E is a rubber pad to increase the friction between the abutment 1212E and the front sheet metal 1191A, so that the front sheet metal 1191A can better support the abutment 1212E.

[0041] The first lower connector 1191 also has a connecting portion 1191C fixed to the front sheet metal 1191A. The connecting portion 1191C is snapped into and / or bolted to the power battery 13 to improve the stability of the connection between the power battery 13 and the frame 11. In one specific implementation, the end of the connecting portion 1191C away from the front sheet metal 1191A is bent backward and downward relative to the front sheet metal 1191A.

[0042] The second upper connector 1212B is provided with a hook 1212F, the end of which is away from the seat body 1211 and bends forward and downward relative to the seat body 1211. The second lower connector 1192 includes a transverse support 1192A and a clamping member 1192B. The transverse support 1192A supports the support tubes on the left and right sides of the upper crossbeam 111, and the thickness direction of the transverse support 1192A is substantially perpendicular to the extension direction of the upper crossbeam 111. The left and right ends of the clamping member 1192B are fixed to the transverse support 1192A, and the middle part of the clamping member 1192B is arched and forms a through hole with the transverse support 1192A. The hook 1212F passes through the through hole from back to front and abuts against the clamping member 1192B to stably fix the middle part of the seat 121 to the frame 11.

[0043] The third upper connector 1212C has two pins 1212G, a locking rod 1212J, and a locking ring 1212K. The two pins 1212G are arranged in the left-right direction. The locking rod 1212J is located behind the two pins 1212G. The locking ring 1212K is sleeved on the locking rod 1212J and threadedly connected to the locking rod 1212J. The third lower connector 1193 has a rear sheet metal 1193A. The thickness direction of the rear sheet metal 1193A is basically perpendicular to the extension direction of the rear connecting section 117. The rear sheet metal 1193A has two insertion holes 1193B. Each pin 1212G is inserted into a socket 1193B. The locking rod 1212J is located at the rear edge of the rear panel 1193A, and the locking ring 1212K is located below the rear edge of the rear panel 1193A. By rotating the locking ring 1212K, the locking ring 1212K abuts against the lower part of the rear panel 1193A, so that the rear end of the seat 121 is stably fixed to the frame 11.

[0044] In one implementation, the power connector 133 is located in the front space 1021 and between the first lower connector 1191 and the second lower connector 1192 to reduce the risk of interference between the power connector 133 and the frame 11.

[0045] Please see Figure 6 The body panel 12 includes a side guard plate 123, which is disposed on the left and right sides of the frame 11. At least part of the side guard plate 123 covers the receiving space 101 and the placement space 102 to protect the structure located in the receiving space 101 and the placement space 102.

[0046] The side guard plate 123 has side ventilation holes 1231 on the left and right sides, and the power battery 13 is exposed from the side ventilation holes 1231 on the left and right sides respectively, so as to facilitate the heat dissipation of the power battery 13.

[0047] The upper side of the side guard plate 123 is provided with an abutment portion 1232, which is located between the frame 11 and the seat cushion 121 body to improve the stability of the connection between the body panel 12 and the frame 11. The abutment portion 1232 is provided with a mounting port 1232A, through which the first lower connector 1191, the second lower connector 1192, and the third lower connector 1193 are exposed to facilitate the connection between the lower connecting assembly 119 and the upper connecting assembly 1212. The power connector 133, the fuse box 181, and the relay 182 are also exposed through the mounting port 1232A to facilitate the disassembly and maintenance of the electrical system 18.

[0048] In one specific implementation, when the axle distance between the front drive wheel 151 and the rear drive wheel 152 is between 1000mm and 1100mm, the motor power in the motor 200 can be selected from 1kW to 3kW. This configuration makes the electric motorcycle 100 suitable for off-road use by teenagers. It should be noted that the wheelbase of the electric motorcycle 100 is the distance between the rotation center of the front drive wheel 151 and the rotation center of the rear drive wheel 152.

[0049] Optionally, the wheel axle spacing between the front traveling wheel 151 and the rear traveling wheel 152 can be any one or any combination of two of the following: 1000mm, 1010mm, 1020mm, 1030mm, 1040mm, 1050mm, 1060mm, 1061mm, 1062mm, 1063mm, 1064mm, 1065mm, 1066mm, 1067mm, 1068mm, 1069mm, 1070mm, 1080mm, 1090mm, and 1100mm.

[0050] Optionally, the motor power in motor 200 can be any one or any combination of two of the following: 1kW, 1.1kW, 1.2kW, 1.3kW, 1.4kW, 1.5kW, 1.6kW, 1.7kW, 1.8kW, 1.9kW, 2kW, 2.1kW, 2.2kW, 2.3kW, 2.4kW, 2.5kW, 2.6kW, 2.7kW, 2.8kW, 2.9kW, and 3kW.

[0051] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
