[0046] The vehicle body comprises a vehicle body shell 1 surrounded by a plate, and an installation space 104 is formed in the vehicle body shell 1;
[0047] The power system is arranged in the installation space 104 and is used to provide power for the motorcycle;
[0048] The front wheel 10 is installed on the front frame 9, and the front part of the vehicle body is connected with the front frame 9;
[0049] The rear wheel 11 is connected with the vehicle body through a flat fork assembly.
[0050] In the present embodiment, the plate is directly used as the vehicle body shell 1 to realize the connection of the front frame 9 and the flat fork assembly. Compared with the prior art, the vehicle body in the present application is directly formed by the plate, and the vehicle body does not need to be formed by welding multiple pipes or the combination of multiple pipes and sheet metal. The structure is simpler, but the overall performance is better due to the overall integrated forming of the vehicle body. The consistency and uniformity of the vehicle body are better, and the weight of the vehicle body is reduced. In particular, the lightweight performance of off-road vehicles and racing cars is improved.
[0051] In the embodiment, the whole vehicle body structure is directly surrounded by the plate material, and the vehicle body is not formed by welding multiple tubes, so that the manufacturing process is optimized, the manufacturing cost of the vehicle body is reduced, the manufacturing efficiency of the vehicle body is higher, meanwhile, the process of assembling the vehicle body to the vehicle body is simplified, and the assembly efficiency is improved.
[0052] In the embodiment, the power system is directly installed into the mounting space 104 formed in the vehicle body shell 1 through the vehicle body shell 1 surrounded by the plate material, and the vehicle body shell 1 can cover the power system, compared with the power system exposed in the prior art, the power system is protected, the service life of the power system is prolonged, and the normal operation of the power system is ensured.
[0053] It is worth noting that in the embodiment, the vehicle body is connected with the front frame 9 and the flat fork assembly, so that the whole motorcycle can be assembled, specifically, the front end of the vehicle body has a fixing part 103, which is fixed by welding with the front frame 9 to realize the stable connection between the front frame 9 and the vehicle body, and the flat fork assembly is fixed with the vehicle body shell 1 by detachable connection in the mounting space 104, and since the whole vehicle body structure is a plate structure in the embodiment, the connection with the flat fork assembly is more convenient, and the assembly efficiency is improved.
[0054] It is also worth noting that in the embodiment, the plate material is cold formed by high-strength high-alloy sheet metal parts, specifically, the vehicle body shell 1 in the embodiment is formed by double-phase steel stamping, which guarantees the smoothness and machining precision of the surface of the plate material, and the overall appearance is better than that of hot forming, and the machining precision is also higher, for example, the material of the plate material in the embodiment can be cold formed by HC / DPD double-phase steel, which has high strength, high rigidity and light weight, and can meet the lightweight demand of the motorcycle and guarantee the strength and rigidity of the vehicle body.
[0055] It is also worth noting that in the embodiment, in addition to the above-mentioned materials, other materials with the same or similar properties can also be used for processing to achieve the same structural strength.
[0056] In an example embodiment, the plate material includes left and right forming plates 101 and 102 arranged left and right, and the left and right forming plates 101 and 102 are welded to form the vehicle body shell 1.
[0057] In the embodiment, the vehicle body shell 1 is connected and formed by two forming plates 101 and 102, and the two forming plates 101 and 102 surround the vehicle body shell 1 and form the mounting space 104.
[0058] Exemplarily, the left forming plate 101 and the right forming plate 102 in the embodiment are two same sheet metal stamping plates, and can be improved according to the requirements of the motorcycle to realize the connection with various parts.
[0059] Exemplarily, in the embodiment, the front ends of the left forming plate 101 and the right forming plate 102 are connected to form a fixing part 103, the front end of the fixing part 103 is arranged obliquely upward, and is used to be connected with the front frame 9. Specifically, the fixing part 103 is a continuously arranged connecting edge, the connecting edge includes a first edge and a second edge, the first edge is a straight edge, and the second edge is a circular arc edge to adapt to the front frame 9.
[0060] Exemplarily, in the embodiment, the left forming plate 101 and the right forming plate 102 are welded and fixed through the fixing part 103, and laser welding is adopted. When welding, the top and the bottom of the left forming plate 101 and the right forming plate 102 are fixed, so that the first forming plate and the second forming plate are fixed. Therefore, the welding process time is short, and the first forming plate and the second forming plate can be quickly connected.
[0061] It is worth noting that, in the embodiment, in order to simplify the process flow, the left forming plate 101 and the right forming plate 102 are not connected at other positions except the fixing part 103, which is more convenient for the assembly of the vehicle body, and is also convenient for the installation of other parts in the vehicle body shell 1, thereby improving the assembly efficiency.
[0062] In another embodiment, in addition to the vehicle body shell 1, the left forming plate 101 and the right forming plate 102 are provided with a lower surrounding plate 105, the lower surrounding plate 105 is integrally arranged with the vehicle body plate, the arrangement mode is integrally formed, a through opening 106 is formed between the lower surrounding plate 105 and the left forming plate 101 and the right forming plate 102, the through opening 106 is communicated with the mounting space 104, and meanwhile, the vehicle body shell 1 is also provided with a cladding structure 2, the cladding structure 2 includes a cladding plate 203 and a connecting frame 201, the connecting frame 201 is fixed on the plate, the cladding plate 203 is fixedly connected with the connecting frame 201, the cladding plate 203 and the connecting frame 201 cover the through opening 106, and the connecting frame 201 is provided with a plurality of fixing strips 202. The cladding structure 2 arranged in the embodiment can also improve the aesthetic performance of the whole vehicle body.
[0063] In the embodiment, since the connecting frame 201 is fixed on the lower surrounding plate 105, the fixing strips 202 are arranged on the connecting frame 201, and the fixing strips 202 on the connecting frame 201 are welded with each other, so that the connection strength between the left forming plate 101 and the right forming plate 102 can be further improved.
[0064] It should be noted that in the embodiment, the plate can also be welded and fixed by a larger number of shaped plates after stamping, and the number of plates can be increased or decreased according to the required conditions of the motorcycle body.
[0065] In an exemplary embodiment, the power system includes a battery 3, a motor 5 and a controller 4 mounted on the body shell 1, and the body shell 1 is provided with a heat dissipation channel in the front-rear direction, and at least one of the battery 3, the motor 5 and the controller 4 is located on the heat dissipation channel.
[0066] In the embodiment, by providing the heat dissipation channel on the body shell 1, the power system can be cooled during operation. Since in the embodiment, the body shell 1 is only connected at the fixed part 103, and the other parts are not connected, when the motorcycle moves forward, air will quickly pass through the mounting space 104 from the front of the body shell 1 and be discharged from the rear of the body shell 1, so this path forms a heat dissipation channel, which is beneficial to the cooling of the power system of the motorcycle.
[0067] For example, in the embodiment, the motor 5 is located directly below the battery 3 and is arranged close to the battery 3, the controller 4 is located on the front side of the battery 3 and the motor 5, the controller 4 is located on the side of the body close to the front wheel 10 and at the inlet end of the heat dissipation channel, the body shell 1 is formed with an exposed groove 108, when the controller 4 is installed, the heat dissipation side 401 (i.e. the front side) of the controller 4 mainly used for heat dissipation is passed out from the exposed groove 108, so that it is exposed outside the exposed groove 108, when the motorcycle moves forward, cold air directly contacts the controller 4 and directly cools the controller 4. In the front part of the body shell 1, an air inlet 107 is provided below the fixed part 103, the air inlet 107 is arranged upwardly and communicates with the mounting space 104, in the embodiment, the inlet end of the heat dissipation channel is the mouth of the exposed groove 108 and the air inlet 107, since the rear part of the body shell 1 is open and can directly communicate with the external environment, the outlet end is the rear part of the body shell 1. Air can enter the mounting space 104 through the air inlet 107 and finally be discharged from the tail of the body shell 1 to improve the air intake of the heat dissipation channel, and the battery 3 and the motor 5 in the mounting space 104 can be continuously cooled during the movement of the motorcycle.
[0068] It is worth mentioning that in the embodiment, since the motor 5 is arranged directly below the battery 3 and close to the bottom of the battery 3, the gap between the battery 3 and the motor 5 should be as small as possible during installation, and the battery 3 is arranged with the longest side in the front-rear direction of the motorcycle during installation, for example, the battery 3 is a cuboid structure, and the longest side is arranged in the front-rear direction of the motorcycle. This layout can reduce the overall height of the motorcycle body, thereby reducing the overall center of gravity of the motorcycle, reducing the seat height, reducing air resistance, and also increasing the distance between the bottom of the motorcycle body and the ground, improving the passing performance of the motorcycle, especially in racing.
[0069] The connecting frame 201 is provided with a mudguard 204, which seals the front and bottom of the vehicle body shell 1 to prevent excessive dust and mud from entering the inside of the vehicle body shell 1. The mudguard 204 and the connecting frame 201 form a heat dissipation cavity 206, which is in the shape of "L" as a whole. The heat dissipation cavity 206 is in communication with the exposed groove 108, and the exposed groove 108 is used to install the controller 4. Therefore, one end of the heat dissipation cavity 206 is in direct contact with the controller 4, and the other end of the heat dissipation cavity 206 leads to the tail of the vehicle body shell 1 and is in communication with the external environment. Therefore, the heat dissipation cavity 206 can also achieve direct heat dissipation of the radiator.
[0070] In the embodiment, the communication grooves 205 are arranged between the adjacent fixed strips 202, which can communicate the heat dissipation cavity 206 and the installation space 104 inside the vehicle body shell 1, thereby dissipating heat for the battery 3 and the motor 5 inside the vehicle body shell 1.
[0071] It is also worth mentioning that in the embodiment, the exposed groove 108, the heat dissipation cavity 206, and the air inlet 107 can improve the heat dissipation effect of the motorcycle. Compared with the three-electric system in the prior art which is directly in contact with the external environment for heat dissipation, the cooperation of the three in the embodiment can achieve the same heat dissipation effect. At the same time, most of the power system is located inside the installation space 104, which can avoid direct contact between the power system and the external environment to protect the power system and improve the dirt resistance of the power system during the operation of the motorcycle.
[0072] It is also worth mentioning that in the embodiment, since an integrated load-bearing vehicle body is adopted, an installation environment is provided for the controller 4. Compared with the controller 4 installed on the battery 3 or the vehicle frame in the prior art, the radiator in the embodiment can dissipate heat by using the airflow when the motorcycle moves forward, which has better heat dissipation effect, thereby ensuring the normal work of the controller 4 and improving the service life of the controller 4, the battery 3, and the motor 5.
[0073] It should be noted that the first mounting frame is used to connect the motor 5 and the controller 4, and the second mounting frame is used to fix the motor 5.

The bolt passes through the second connecting portion 308 and the second positioning hole and is connected with the nut. The nut fixes the pressing plate 307 on the second connecting piece 309 and presses the battery 3 tightly on the support frame 301.
[0077] In an exemplary embodiment, since the battery 3 is a cuboid structure laid horizontally, the support frame 301 in the embodiment is in the shape of "X" as a whole, so as to stably support the bottom of the battery 3. The pressing plate 307 is similar to the shape of "big" character, so as to realize the function of fixing the battery 3.
[0078] In an exemplary embodiment, the support frame 301 is provided with a limiting seat 306, which can be used for positioning the outer edge of the battery 3.
[0079] It is worth mentioning that a limiting assembly is further arranged between the battery 3 and the pressing plate 307, and through the limiting assembly, the battery 3 can be further fixed with the pressing plate 307, so as to avoid dislocation between the top of the battery 3 and the pressing plate 307.

[0081] In an exemplary embodiment, the flat fork assembly comprises a flat fork shaft 7 and a flat fork body 6, wherein the flat fork body 6 is provided with a pressing sleeve 603, the flat fork shaft 7 is fixedly connected to the vehicle body, and the two ends of the flat fork shaft 7 are provided with combined bearings, and the flat fork body 6 is rotatably connected to the flat fork shaft 7 through the combined bearings.
[0082] In this embodiment, the flat fork assembly is an important part of the motorcycle, which is a suspension component. The flat fork is rotatably connected to the motorcycle axle through the flat fork shaft 7. In the prior art, the shaft tube of the steel welded flat fork is rotatably connected to the axle through a bearing, such as a needle bearing. This has the advantages of small rotational resistance and controllable radial clearance. However, the axial clearance is difficult to control, and a single bearing such as a needle bearing cannot be used to position the shaft tube axially. In order to avoid structural interference with the frame, an axial gap is left between the flat fork shaft 7 and the vehicle body during design. Therefore, when the flat fork main body 6 is subjected to axial and radial forces (such as during turning), the existing bearing cannot support the radial load of the motorcycle. After the flat fork system is subjected to the radial load, the flat fork main body 6 may move axially, causing wear to the vehicle body and a decrease in the synchronization of the front and rear wheels 11.
[0083] In this embodiment, the flat fork assembly can support and fix the rear wheel 11, and the combined bearing can act on the axial and radial directions of the flat fork shaft 7.
[0084] For example, the flat fork shaft 7 is provided with a shaft sleeve 701, the shaft sleeve 701 is provided with a first positioning seat 802 and a second positioning seat 803 for positioning the bearing assembly 8, the first positioning seat 802 abuts against the end face of the first bearing 801, the bearing assembly 8 includes the first bearing 801, the second bearing 804, and the third bearing 805, the first bearing 801 is sleeved on the shaft sleeve 701 and located between the first positioning seat 802 and the second positioning seat 803, the first bearing 801 is pressed on the shaft sleeve 701 by the pressing sleeve 603, the first bearing 801 is pressed on the first positioning seat 802 by the pressing sleeve 603, and the second bearing 804 is pressed on the second positioning seat 803 by the pressing sleeve 603. The first shaft sleeve 701 has a first acting part 8011 and a second acting part 8012, the first acting part 8011 is sleeved on the shaft sleeve 701 and acts on the axial direction of the flat fork shaft 7, and the second acting part 8012 acts on the radial direction of the flat fork shaft 7. The second bearing 804 has a third acting part 8041, and the third bearing 805 has a fourth acting part 8051, both the third acting part 8041 and the fourth acting part 8051 act on the radial direction of the flat fork shaft 7, and the third acting part 8041 and the fourth acting part 8051 are arranged opposite to each other. In this embodiment, the second bearing 804 and the third bearing 805 also act on the radial direction of the flat fork shaft 7, thereby further improving the support of the radial load. Specifically, when the flat fork shaft 7 is subjected to a radial load, the radial load is transmitted to the shaft sleeve 701, and the second bearing 804 and the third bearing 805 bear the radial load respectively. The second bearing 804 and the third bearing 805 are arranged on both sides of the first bearing 801, and the third acting part 8041 and the fourth acting part 8051 are arranged opposite to each other. Therefore, in the case of left turning and right turning of the motorcycle, the radial load can be supported.
[0085] Exemplary, in this embodiment, the pressing sleeve 603 has a first pressing part 6031 and a second pressing part 6032, the first pressing part 6031 presses the first bearing 801 on the shaft sleeve 701, the second pressing part 6032 presses the second bearing 804 on the first positioning seat 802, and the second pressing part 6032 presses the third bearing 805 on the second positioning seat 803. The cross section of the pressing sleeve 603 is "T" shaped as a whole, the middle downward part is the first pressing part 6031, the first bearing 801 is clamped to press the first bearing 801 on the shaft sleeve 701, and the top horizontal part is the second pressing part 6032, the second pressing part 6032 synchronously presses the second bearing 804 and the third bearing 805, therefore, the three bearings can be pressed at the same time through the pressing sleeve 603 on the fork body 6, and the fixing effect is better.
[0086] Exemplary, the left and right ends of the fork shaft 7 are rotatably connected to the vehicle body, the fixed sleeve 702 is arranged between the shaft sleeves 701 arranged at the two ends of the fork shaft 7, and the mounting gap is arranged between the shaft sleeve 701 and the fixed sleeve 702. The shaft sleeve 701 and the fixed sleeve 702 arranged can protect the fork shaft 7, to a certain extent, can avoid damage to the fork shaft 7, and can also be used for positioning of the second positioning seat 803. Specifically, the second positioning seat 803 is "T" shaped, during installation, the second positioning seat 803 is first installed on the fork shaft 7, so that the end surface of the second positioning seat 803 abuts against the fixed sleeve 702, then the shaft sleeve 701, the third bearing 805 and the shaft sleeve 701 are installed, then the first bearing 801 is sleeved on the shaft sleeve 701, then the first positioning seat 802 and the second bearing 804 are installed, and finally the pressing sleeve 603 is clamped on the first bearing 801, so that the installation of the bearing assembly 8 is realized.
[0087] Exemplary, in this embodiment, the fork shaft 7 is provided with a stop block 806, and the stop block 806 is connected with the vehicle body. Because the stop block 806 is arranged, even if the bearing fails and the fork shaft 7 produces axial movement, the fork shaft 7 will rub against the stop block 806, and will not rub against the vehicle body, and the stop block 806 can be replaced
[0088] Exemplary, the fork body 6 includes a left fork 601 support and a right fork 602 support, the left fork 601 support and the right fork 602 support are both provided with a pressing sleeve 603, and the left fork 601 support and the right fork 602 support are provided with a connecting block for mutual connection.
[0089] In the embodiment, the flat fork body 6 is a left flat fork 601 and a right flat fork 602, and both are provided with a pressing sleeve 603, so the bearing assembly 8 is two, which are respectively arranged on the pressing sleeve 603 of the left flat fork 601 and the right flat fork 602, and the bearing assembly 8 on the left flat fork 601 and the bearing assembly 8 on the right flat fork 602 are symmetrically arranged, so that the flat fork shaft 7 can be supported in the axial and radial directions when the motorcycle turns left and right, to avoid the circumferential movement of the flat fork shaft 7.
[0090] For example, a plurality of reinforcing ribs 604 are arranged on the left flat fork 601 and the right flat fork 602. The reinforcing ribs 604 can improve the structural strength of the left flat fork 601 and the right flat fork 602.
[0091] It is worth noting that the combined bearing in the embodiment adopts the structure described above, and three bearings are used in cooperation to act on the axial and radial directions of the flat fork shaft 7. In the case that the flat fork body 6 bears axial force and radial force, the axial direction of the flat fork shaft 7 is supported and limited, and the radial direction of the flat fork shaft 7 is also supported and limited, avoiding the axial movement of the flat fork shaft 7 and improving the consistent performance of the front and rear wheels 11.
[0092] It is also worth noting that other structures of the combined bearing can also be used in the embodiment, and the specific structure of the combined bearing is not limited, but it needs to meet the requirements of limiting the axial direction of the flat fork shaft 7 and limiting the radial direction of the flat fork shaft 7, such as additionally arranging a fixing structure on the flat fork body 6 to fix the combined bearing on the flat fork body 6, supporting and limiting the flat fork body 6.
[0093] In an exemplary embodiment, the motorcycle also has a shock absorber 13, and the motorcycle also has a tail stand 12, the tail stand 12 is provided with a cushion, and the tail stand 12 is installed on the top of the vehicle body shell 1.
[0094] In summary, the integrated load-bearing vehicle body structure is adopted in the utility model, the vehicle body shell 1 is directly processed and formed by a plate material, the lightweight performance of the motorcycle is improved, the manufacturing process is optimized, the manufacturing cost of the vehicle body is reduced, the manufacturing efficiency is increased, and the assembly process flow is simplified, and at the same time, the overall vehicle body shape is more beautiful, so the integrated load-bearing vehicle body improves the comprehensive performance of the motorcycle.
