The brake caliper 1718e is fixed to the reduction gear 174, specifically, to the third cover plate 1718, by at least two bolts. In the prior art, for the assembly direction, the fixing bolt between the third cover plate and the housing is generally assembled from the third cover plate side to the housing side, but when the brake caliper is directly mounted on the third cover plate, the brake caliper may affect the mounting of the bolt between the third cover plate and the housing. If the bolt is mounted from the right to the left in the first direction, i.e. in a direction opposite to the fourth direction, the head of the bolt is now located between the third cover plate of the reduction gear and the brake caliper. In order to seat the head of the bolt, there is at least a gap between the third cover plate and the brake caliper, which can accommodate the head of the bolt, so that the distance between the third cover plate and the brake caliper is undoubtedly increased, which is not favorable for realizing the compact structure. To counteract this adverse effect while still maintaining the drive assembly 17 in a compact relationship with the brake caliper 1718e, or the reduction unit 174 in a compact relationship with the brake caliper 1718e, at least one of the bolts in the bolt set is assembled in the fourth direction 102 from the side of the housing 171 toward the side of the third cover plate 1718. When the bolts that secure the drive housing 171 to the third cover 1718 are installed in the fourth direction 102, the heads of the bolts are not located between the third cover 1718 and the brake caliper 1718e, and there is no space between the third cover 1718 and the brake caliper 1718e, and the distance between the third cover 1718 and the brake caliper 1718e can be further reduced, thereby making the entire structure more compact. The bolts that are assembled from the case 171 side toward the third cover 1718 side in the fourth direction 102 are fixed by through holes or blind holes provided in the third cover 1718 with internal threads. The end of the threaded rod of the bolt is located inside the third cover 1718, so that at the corresponding position of the brake calliper 1718e there are no parts protruding from the third cover 1718 and interfering with and affecting the brake calliper 1718 e.

A wheel housing 123 is provided on the rear wheel 122 on the side remote from the drive assembly 17. The rear wheel 122 of the motorcycle is the driving wheel of the vehicle, and one side thereof is connected to the driving unit 17, while the other side is normally completely exposed. During the running process of the vehicle, dust, muddy water and even sand and stones which are occasionally splashed can damage the wheel from one side, and the muddy water and the sand and stones can also penetrate through the spoke of the wheel to damage the driving assembly or the braking device on the other side, so that the driving assembly 17 or the braking device fails or the driving assembly 17 or the braking device is damaged. The above conditions can cause damage to the vehicle in different degrees, influence the service life of each part in the vehicle, and then influence the service life of the vehicle, or directly cause direct influence on the running safety of the vehicle. The wheel cover 123 is arranged on one side of the wheel opposite to the driving assembly 17, so that certain isolation effect can be achieved between dust, muddy water, sand and stone and the interior of the wheel, the wheel is protected from being influenced and damaged by the factors, the service life of the wheel and related parts is guaranteed, and the running safety of the vehicle is also guaranteed.

As shown in fig. 12 and 13, a fixing ball 1221 is disposed on a surface of the rear wheel 122 contacting the wheel housing 123, and a fixing ball seat 1231 corresponding to the fixing ball 1221 is disposed on the wheel housing 123. The retaining bulb 1221 is provided on the hub 1222, rim 1223 or spokes 1224 of the rear wheel 122. The wheel housing 123 is fixedly connected to the wheel in a detachable manner. In a normal situation, the wheel housing 123 is fixedly connected with the rear wheel 122, and when necessary, for example, when the wheel is overhauled, the wheel housing 123 can be detached, so that the wheel can be conveniently inspected and maintained, and the wheel housing 123 can be conveniently replaced. The wheel housing 123 may also be provided with a plurality of openings 1232, which reduces the weight of the wheel housing 123 and enables better control of the weight of the entire vehicle. Meanwhile, the opening 1232 is provided to facilitate the user to partially observe the inside of the rear wheel 122 and even the usage of the driving assembly 17 without disassembling the wheel housing 123.

Meanwhile, the detachable connection mode can facilitate users to change the styles or patterns of the wheel covers 123 according to own preferences, so that the vehicle-using requirements of occasions where the vehicles do not pass are met, and more choices are provided for the users. As an implementation manner, at least three fixed ball heads 1221 are arranged on the wheel, and a fixed ball seat 1231 matched with the fixed ball heads 1221 is correspondingly arranged on the wheel housing 123.

The wheel housing 123 is detachably and fixedly connected with the wheel through a fixed ball head 1221 and a fixed ball seat 1231 which are matched with each other. The fixing ball 1221 is disposed on the wheel, and may be disposed on any one of the hub 1222, the spoke 1224, or the rim 1223, and in order to ensure the stability of the connection, the fixing ball 1221 is disposed on the wheel at equal intervals along the wheel axis. In order to ensure stability, the number of the fixed ball heads 1221 on the wheels is not less than three. The arrangement of five fixed bulbs 1221 on the wheel is a better choice, so that the fixing stability cannot be influenced due to the small number of the fixed points, the cost cannot be increased due to the excessive number of the fixed points, and the difficulty in disassembly cannot be caused. As shown in fig. 11, the fixing ball seat 1231 is formed of a pair of half ball seats which are oppositely arranged. In the fixing ball seat 1231 formed of the pair of hemispherical seats, the opening size is smaller than that of the fixing ball head 1221. The pair of hemispherical seats form a cavity for accommodating the ball head, and the size of the cavity is larger than or equal to that of the ball head. The wheel housing 123 and the wheel are detachably and fixedly connected in a way that the fixed ball head 1221 and the fixed ball seat 1231 are matched with each other. A pair of half-ball seats are oppositely arranged to form a spherical cavity with a certain size capable of accommodating the fixing ball head 1221, the spherical cavity is provided with an opening for the fixing ball head 1221 to pass through, and the size of the opening is smaller than that of the fixing ball head 1221. Since the fixing ball seat 1231 is formed of a pair of relatively independent hemispherical seats, the fixing ball seat 1231 has a certain deformability. When the wheel house 123 is installed, the opening part of the fixed ball seat 1231 is extruded by the fixed ball head 1221, deformation occurs between the two half ball seats, the fixed ball head 1221 enters the cavity of the fixed ball seat 1231, the fixed ball seat 1231 limits the fixed ball head 1221, and the fixed ball head 1221 is prevented from being separated from the fixed ball seat 1231. The connection between the fixed ball head 1221 and the fixed ball seat 1231, that is, the connection between the wheel housing 123 and the rear wheel 122, is realized.

Some conventional electric bicycles have a vehicle control unit, but most vehicles only have partial units in the vehicle control unit in the implementation mode, and can only realize simple vehicle control functions, such as control of a vehicle lighting system and motor control. And secondly, the integration level of the whole vehicle controller of most vehicles is low, the whole vehicle controller only has two to three functions in the whole vehicle controller of the vehicle in the implementation mode, other functions are not equipped or dispersed in other devices of the vehicle, integrated unified management cannot be carried out, and the problems that the information processing speed is low, the vehicle control delay is large, the dispersed parts occupy large space and the dispersed parts consume high energy are solved. In this implementation manner, the micro control unit 181, the sound effect control unit 185, the CAN communication unit 1861, the wireless communication unit 186, and the information output unit 184 are integrated into one vehicle controller 18, and the vehicle controller has the advantages of high integration level, fast information processing, fast vehicle control, small occupied area, low energy consumption, and the like. Meanwhile, the integration level is high, the device can be modularly used for various vehicle types, the units and the modules do not need to be rearranged due to different vehicle types, and the research and development cost can be reduced.

As one implementation, as shown in fig. 15 and 16, the lighting assembly 14 includes a headlight assembly 141, and the headlight assembly 141 integrates a high beam 1411, a low beam 1412, and left and right turn lamps 1413 provided on left and right sides. In a conventional electric scooter, the headlight assembly 141 is often integrated with only a high beam 1411 and a low beam 1412, and the left and right turn lights 1413 are separately provided near left and right handlebars, respectively. Although the space requirement of the headlight unit 141 can be satisfied, the integration level of the headlight of the vehicle is low, and the wiring is more complicated. Simultaneously, control indicator 1413 sets up near the handlebar alone, has intensity lower, the easy problem such as damage of colliding with that takes place, can cause about indicator 1413's life lower, need change frequently, increase use cost.

In the present embodiment, the headlight unit 141 and the front body cover 131 are assembled in advance to form a front unit, and the assembled front unit is fixed to the front frame 111. The existing common mounting mode of the headlamp assembly and the front automobile body covering part is that the headlamp assembly and the front automobile body covering part are respectively mounted on a front automobile frame, the headlamp assembly and the front automobile body covering part need to be accurately matched in pairs when mounted on the front automobile frame, the headlamp assembly and the front automobile frame need to be perfectly matched, the front automobile body covering part and the front automobile frame need to be perfectly matched, so that the headlamp assembly and the front automobile body covering part can be perfectly matched, and gaps are uniform. The headlamp assembly and the front automobile body covering part are respectively installed, so that the difficulty in production and manufacturing of the two parts of assemblies can be reduced, but perfect assembly can be realized only by the fact that the headlamp assembly and the front automobile body covering part have high processing progress and assembly progress.

Due to the fact that errors exist in manufacturing, the headlamp assembly or the front automobile body covering piece cannot completely meet the design requirements in manufacturing, and the headlamp assembly and the front automobile body covering piece cannot be assembled completely and accurately when being mounted on a front frame, and the problem that gaps are not uniform between the headlamp assembly and the front automobile body covering piece after assembly is caused. The problem that gaps are inconsistent often exists after the headlamp assembly and the front automobile body covering part are respectively installed on a front automobile frame, the attractiveness of an automobile is affected due to the problem, meanwhile, the performance of water resistance and the like of the automobile is adversely affected, the problem that water enters the front automobile body easily due to the fact that gaps of parts of matching positions are too large exists, and potential safety hazards exist. The headlamp assembly is assembled with the front body cover, and then the front assembly assembled by the headlamp assembly and the front body cover is mounted to the frame. Because the headlamp assembly and the front automobile body covering part are installed in advance, the installation gap between the headlamp assembly and the front automobile body covering part can be controlled in the assembling process, and the gap is uniformly distributed. Meanwhile, only the assembling relation between the headlamp assembly and the front automobile body covering part needs to be considered during the assembling process, and the assembling difficulty is reduced. When the front assembly is assembled with the frame, only the assembling relation between the front assembly and the front frame, namely the assembling relation between the front body covering part and the frame, needs to be considered.

In the implementation mode, the headlamp assembly 141, the front body cover 131 and the front frame 111 can be assembled only by considering the assembly relationship between the headlamp assembly 141 and the front body cover 131 and the relationship between the front body cover 131 and the front frame 111 in sequence, and the effects of the two assemblies can be directly obtained in the assembly process and timely adjusted. In the assembling mode that the headlamp assembly 141 and the front body cover 131 are respectively installed on the front frame 111, the assembling effect between the headlamp assembly 141 and the front body cover 131 can only be obtained after the headlamp assembly is completely installed, and cannot be obtained in time in the assembling process, and in case that a problem occurs in the previous assembling stage, the problem cannot be corrected in time, and the adjustment cost is relatively high.

In this embodiment, the headlight unit 141 may be fixedly connected to the front body cover 131 by a bolt or may be fixedly connected by a snap connection. The connection manner between the headlight unit 141 and the front body cover 131 is not necessarily limited to the above connection manner, and may be any connection manner capable of connecting the headlight unit 141 and the front body cover 131 together. In the present embodiment, a front unit, which is assembled from the headlight unit 141 and the front body cover 131, is attached to the front frame 111, and the fixing points thereof to the front frame 111 are located on the headlight unit 141 and the front body cover 131, respectively. The inner side of the headlight assembly 141 is further provided with a positioning chute 1414, and a guide block 1111 is provided at a corresponding position of the front frame 111. Headlamp assembly 141 may be assembled under the force of gravity with the cooperation of positioning runner 1414 and guide block 1111. After the assembly is completed, the mounting holes in the front body cover 131 are aligned with the corresponding mounting holes of the front frame 111, so that the subsequent fixed connection of devices such as bolts can be conveniently carried out. The arrangement of the positioning chute 1414 and the guide block 1111 plays a role in fixing the headlamp assembly 141 or the front assembly, and also plays a role in positioning the mounting site between the front automobile body covering part 131 and the front automobile frame 111, so that the positioning can be conveniently and accurately performed, the matching of the positioning chute 1414 and the guide block 1111 has bearing capacity, the fixed assembly between the front automobile body covering part 131 and the front automobile frame 111 can be completed without supporting operation after the assembly, the labor can be saved, and the efficiency can be improved.

As an implementation manner, a USB interface is disposed on the front body cover 131, and an interface cover assembly 134 is disposed on the USB interface, as shown in fig. 17 and 18, the interface cover assembly 134 includes an interface cover base 1341 for accommodating the USB interface and an interface cover 1342 for covering the USB interface. Interface cover base 1341 is sleeved on the outer side of the USB interface, and interface cover base 1341 is fixedly connected with the USB interface. As shown in fig. 19, the interface cover base 1341 is provided with a limiting hole 1341a, and the interface cover 1342 is provided with a limiting post 1342a matching with the limiting hole 1341 a. The end of the limiting post 1342a on the interface cover 1342 is provided with an anti-drop structure, and after the limiting post 1342a is matched with the limiting hole 1341a, the limiting post 1342a cannot be separated from the limiting hole 1341a without the action of external force. After the interface cover plate 1342 is mated with the interface cover base 1341, the interface cover plate 1342 can rotate about the axial line of the retaining posts 1342 a. With the coming of the era of vehicle intelligence, along with the wide application of smart devices such as mobile phones, the smart devices are always charged in the traveling process, and the charging interfaces are increasingly required to be paid attention to when the smart devices are used by electric vehicles, so that the charging interfaces such as corresponding USB (universal serial bus) are generally selected to be arranged on fuel vehicles or electric vehicles. In the driving process of a vehicle, especially when the USB interface is in an idle state, a protective cover is often disposed on the USB interface to protect the USB interface.

In the prior art, a USB interface protective cover is directly covered on a USB interface, and the USB interface protective cover is separated from a USB interface or a component where the USB interface is located after being opened. The other type of the interface protection cover is that a connecting part is arranged between the interface protection cover and the USB interface or a component where the USB interface is located, the interface protection cover still keeps connection with the USB interface or the component where the USB interface is located after being opened, the risk that the interface protection cover is lost is reduced, and the problem that the connecting part is easy to damage still exists. Meanwhile, the connecting part of the protective cover has certain elasticity after the interface protective cover is opened, so that the interface protective cover has a covering trend, and great inconvenience exists when the connector protective cover is used by one hand. In this implementation, the interface cover assembly 134 includes an interface cover base 1341 sleeved outside the USB interface and an interface cover plate 1342 mutually matched with the interface cover base 1341. Interface cover 1342 is provided with a limiting post 1342a, interface cover base 1341 is provided with a limiting hole 1341a, and limiting post 1342a and limiting hole 1341a are mutually matched, so that interface cover 1342 is connected with interface cover base 1341. The end of the limiting post 1342a on the interface cover 1342 is provided with an anti-falling mechanism 1342b, so that the limiting post 1342a cannot easily fall off from the limiting hole 1341a after being matched with the limiting hole 1341a, that is, the interface cover 1342 cannot easily fall off after being matched with the interface cover base 1341, and thus, the interface cover 1342 can still be connected with the interface cover base 1341 after being opened, and the problem that the interface cover 1342 is lost is solved. Meanwhile, due to the arrangement of the limiting posts 1342a and the limiting holes 1341a, the interface cover 1342 may rotate along the axial line of the limiting posts 1342a, that is, the interface cover 1342 may rotate around the limiting holes 1341a in the interface cover base 1341. After the interface cover plate 1342 is opened, the interface cover plate 1342 is opened at a certain angle manually or under the action of gravity, so that the USB interface can be used conveniently, and the USB interface can be used conveniently by one hand. The top of interface cover base 1341 is flush with or slightly above the top of the USB interface. However, when the top of the USB interface is higher than the interface cover base 1341, the structure of the protruding portion of the USB interface needs to be protected by the interface cover 1342, which undoubtedly increases the thickness of the interface cover 1342, and further increases the weight of the interface cover 1342, the interface cover 1342 is connected with the interface cover base 1341 through the matching structure of the limiting post 1342a and the limiting hole 1341a, and the anti-drop structure is kept connected in the open state of the interface cover 1342 through the anti-drop structure at the end of the limiting post 1342a, and the increase of the weight of the interface cover 1342 increases the pressure of the anti-drop structure, so that the weight of the interface cover 1342 is reduced as much as possible, and the service life of the anti-drop structure can be correspondingly prolonged. Meanwhile, the USB interface is not higher than the interface cover base 1341, and the purpose of protecting the USB interface can be better achieved under the use state of the USB interface.

The inside of the side wall of the interface cover 1342 is provided with a fixing protrusion, and the outside of the side wall of the interface cover base 1341 is provided with a fixing buckle matched with the fixing protrusion.
