Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an electric two-wheeled vehicle. Background Technology

[0002] With the increasing emphasis on environmental protection and energy conservation in society, electric two-wheelers, as a green, energy-saving, and emission-reducing mode of transportation, are playing an increasingly important role in public transportation.

[0003] In the design of electric two-wheelers, the front fender is a crucial functional component, primarily used to block mud, gravel, and other debris kicked up by the front wheel during driving, thus protecting the vehicle structure and improving driving safety. In related technologies, the front fender is typically bolted to the front of the frame. Its size is limited by the support strength of the mounting point and the layout of the vehicle structure, resulting in a relatively small protection area and inadequate protection. Since the front of the frame is far from the front wheel, extending the front fender to improve protection would increase its weight and make vibration transmission more pronounced, leading to instability in the fender installation and seriously affecting driving safety. Utility Model Content

[0004] This application provides an electric two-wheeled vehicle whose front mudguard can improve the protection effect while ensuring installation stability.

[0005] This application provides an electric two-wheeled vehicle, including a frame, a running system, a suspension system, a power system, and a front fender. The frame includes a front frame, a mid-frame located behind the front frame, and a first front support member; the running system includes a front wheel, at least partially located below the front frame; the suspension system includes a lower connecting plate connected to the front frame, and the first front support member is mounted on the lower connecting plate; the power system is supported by the mid-frame; the front fender forms a cover space, and a portion of the front wheel and the first front support member are located within the cover space; wherein, the ground clearance of the lowest position of the front fender is less than the ground clearance of the front wheel axle; the first front support member includes two support arms, which support the front fender on both sides in the width direction of the electric two-wheeled vehicle and extend downwards towards the electric two-wheeled vehicle; the length of the support arms is L1, and the distance between the highest and lowest points of the front fender is the length L2 of the front fender, where L1 > L2 / 2.

[0006] In at least one embodiment, the first front support includes a connecting portion connected between two support arms, the connecting portion being mounted on the lower connecting plate and supporting the upper part of the front fender.

[0007] In at least one embodiment, one end of the support arm is connected to the connecting portion, and the other end is provided with a support arm connector, which detachably connects the front fender and the support arm.

[0008] In at least one embodiment, the suspension system includes two front shock absorbers connected to the lower connecting plate and the axle of the front wheel. The two front shock absorbers are arranged opposite to each other and parallel in the left-right direction of the electric two-wheeler. When viewed from the left side of the electric two-wheeler, the front fender covers the front shock absorbers.

[0009] In at least one embodiment, the support arm is disposed on the side of the front shock absorber facing the front of the electric two-wheeler and extends away from the front shock absorber.

[0010] In at least one embodiment, an angle is formed between the extension direction of the support arm and the extension direction of the front shock absorber, the angle ranging from 10 degrees to 30 degrees.

[0011] In at least one embodiment, the front fender includes at least two detachable, interlocking shields.

[0012] In at least one embodiment, the front fender includes four baffles, namely a first baffle, a second baffle, a third baffle, and a fourth baffle.

The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0024] like Figure 1 and Figure 2 As shown, this application provides an electric two-wheeled vehicle 100, which includes a frame 10, a body panel 20, a running gear 30, a suspension system 40, and a power system 50. It is understood that... Figure 1 The electric two-wheeler 100 shown is an electric-powered motorcycle.

[0025] The body panel 20 at least partially covers the frame 10. The running gear 30 is at least partially disposed under the frame 10, and includes front wheels 31 and rear wheels 32. The suspension system 40 connects the front wheels 31 and rear wheels 32 to the frame 10. The power system 50 is supported by the frame 10, connected to the running gear 30, and used to drive the running gear 30. For example, the power system 50 drives the rear wheels 32 to rotate.

[0026] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 and Figure 2The directions shown are front, back, left, right, up, and down. In this embodiment, the front, back, left, right, up, and down directions refer to the directions when the electric two-wheeled vehicle 100 is on a horizontal plane. The front-back direction refers to the length direction of the electric two-wheeled vehicle 100 provided in this application. The left-right direction refers to the width direction of the electric two-wheeled vehicle 100 provided in this application. The up-down direction refers to the height direction of the electric two-wheeled vehicle 100 provided in this application.

[0027] As one implementation method, such as Figure 2 As shown, the frame 10 includes a front frame 11, a middle frame 12, and a rear frame 13 connected in sequence. Viewed along the length of the electric two-wheeler 100, the frame 10 is substantially symmetrical about its central axis.

[0028] In some embodiments, the front frame 11 includes a head tube 111 and a main tube 112, with the main tube 112 connected to the middle portion of the head tube 111. The front wheel 31 is connected to the head tube 111 via a suspension system 40, specifically, the suspension system 40 includes a front shock absorber 41, through which the front wheel 31 is connected to the head tube 111.

[0029] Please see Figure 2 In some embodiments, the mid-frame 12 includes a pair of longitudinal beams 121 extending along the front-rear direction of the electric two-wheeler 100 and a crossbeam 122 extending along the width direction of the electric two-wheeler 100 and connecting the two longitudinal beams 121. Exemplarily, the two longitudinal beams 121 are disposed on the left and right sides of the electric two-wheeler 100, with one end of each beam connected to the left and right sides of the lower part of the front frame 11, and the other end connected to the rear frame 13. The longitudinal beams 121 and the crossbeam 122 enclose an accommodating space 123. Specifically, the power system 50 includes a battery assembly 51, which is disposed within the accommodating space 123.

[0030] In some embodiments, the mid-frame 12 includes a pair of sub-beams 124 extending along the longitudinal direction of the electric two-wheeler 100. The two sub-beams 124 are disposed on the left and right sides of the electric two-wheeler 100 and below the longitudinal beam 121. One end of the sub-beam 124 is connected to the bottom of the main beam 112, and the other end of the sub-beam 124 is connected to the rear frame 13.

[0031] Please see Figure 1 , Figure 3 and Figure 4 As one implementation, the body panel 20 includes a front fender 21, which covers the front wheel 31. The front fender 21 partially covers the left and right sides of the front wheel 31, and the ground clearance of the lowest position of the front fender 21 is lower than the ground clearance of the axle 311 of the front wheel 31.

[0032] The suspension system 40 includes a lower control plate 42, which is connected to the front frame 11. For example, the lower control plate 42 is connected to the head tube 111, and the front shock absorber 41 is connected to the head tube 111 via the lower control plate 42.

[0033] The frame 10 includes a first front support member 14 mounted on the lower connecting plate 42. A front fender 21 forms a cover space. A portion of the front wheel 31 and the first front support member 14 are located within the cover space, and the first front support member 14 is supported below the front fender 21. (See reference...) Figure 3 and Figure 5 The first front support member 14 includes two support arms 141, which are supported on both sides of the front fender 21 in the width direction of the electric two-wheeler 100. One end of each support arm 141 is connected to one side of the front fender 21 in the width direction of the electric two-wheeler 100 and extends downward toward the lower side of the electric two-wheeler 100, while the other end extends toward the lower connecting plate 42. The length of each support arm 141 is L1, which is the straight-line distance between its two opposite ends. The length of the front fender 21 is the distance between its highest and lowest points, and is L2, where L1 > L2 / 2.

[0034] The lowest position of the front fender 21 is positioned below the axle 311 of the front wheel 31, increasing the size of the front fender 21 to increase the coverage area of ​​the front fender 21 over the front wheel 31, thereby improving the protection of the front wheel 31 by the front fender 21. By setting the length of the support arm 141 to be greater than half the length of the front fender 21, the support distance for the front fender 21 is increased, thereby improving the stability of the front fender 21. The two support arms 141 can support the left and right sides of the front fender 21, improving the problem of easy swaying caused by the large size of the left and right sides of the front fender 21, improving the installation stability of the front fender 21 and the driving safety of the electric two-wheeled vehicle 100.

[0035] See Figure 3 and Figure 5 In some embodiments, the first front support member 14 includes a connecting portion 142, which connects between two support arms 141. The connecting portion 142 is mounted on the lower connecting plate 42 and supports the upper part of the front fender 21. The two support arms 141 are mounted on the lower connecting plate 42 via the connecting portion 142, and the connecting portion 142 can support the upper part of the front fender 21. Thus, in cooperation with the two support arms 141, the left and right sides and the upper part of the front fender 21 are supported, improving the stress stability of the front fender 21.

[0036] The fixing method between the connecting part 142 and the lower connecting plate 42 may include, but is not limited to, welding, bolting, screwing, and snap-fit ​​fixing. For example, the connecting part 142 may be detachably connected to the lower connecting plate 42 by means of bolts and nuts.

[0037] In some embodiments, there is a gap between the middle part of the support arm 141 and the front mudguard 21, that is, the middle part of the support arm 141 does not contact the front mudguard 21. The first front support member 14 supports and fixes the front mudguard 21 only through a section of the support arm 141 and the connecting part 142. This can reduce the friction and wear between the support arm 141 and the front mudguard 21, so that the front mudguard 21 has a certain deformation margin when the vehicle vibrates during driving, reducing the risk of the front mudguard 21 breaking.

[0038] See Figure 3 In some embodiments, one end of the support arm 141 facing the lower connecting plate 42 is connected to the connecting part 142, and the other end is provided with a support arm connector 143, which detachably connects the front fender 21 and the support arm 141.

[0039] The support arm connector 143 can fix the end of the support arm 141 away from the connector 142 to the front mudguard 21, thereby further improving the support stability of the support arm 141 on the front mudguard 21 and reducing the situation where the support arm 141 sways on bumpy road sections, causing the front mudguard 21 to be unstable under force.

[0040] In some embodiments, the support arm connector 143 is a screw that passes through and connects the support arm 141 and the front fender 21; or the support arm connector 143 includes a bolt and a nut, with the bolt passing through the support arm 141 and the front fender 21 and locked with the nut.

[0041] In some embodiments, the first front support 14 is a sheet metal part, which has good structural strength compared to plastic parts.

[0042] See Figure 1 and Figure 4 In some embodiments, two front shock absorbers 41 are provided. The front shock absorber 41 connects the lower connecting plate 42 and the axle 311 of the front wheel 31. The two front shock absorbers 41 are arranged opposite to each other and parallel to each other in the left and right direction of the electric two-wheeled vehicle 100. When viewed from the left side of the electric two-wheeled vehicle 100, the front mudguard 21 covers the front shock absorber 41.

[0043] The front mudguard 21 shields the front shock absorber 41 from the side of the electric two-wheeler 100, thereby protecting the front shock absorber 41 and reducing the impact of debris such as gravel and mud kicked up by the front wheel 31 on the front shock absorber 41 during driving.

[0044] See Figure 2 and Figure 3 In some embodiments, the support arm 141 is disposed on the side of the front shock absorber 41 facing the front of the electric two-wheeler 100 and extends away from the front shock absorber 41.

[0045] When the electric two-wheeler 100 is in motion, the front part of the front fender 21 is subjected to significant airflow impact. The support arm 141 supports the portion of the front fender 21 located in front of the front shock absorber 41, thereby improving the structural strength of the front part of the front fender 21 and enhancing its resistance to airflow impact. Furthermore, the support arm 141 is positioned away from the front shock absorber 41, thus avoiding interference with its normal operation.

[0046] See Figure 2 and Figure 3 In some embodiments, an angle B is formed between the extending direction of the support arm 141 and the extending direction of the front shock absorber 41, with the angle B ranging from 10 degrees to 30 degrees. Specifically, viewed from the left or right side of the electric two-wheeled vehicle 100, the extending direction of the support arm 141 is the extending direction of the line P1 connecting the fixing point of the support arm 141 and the front fender 21 to the connection point of the support arm 141 and the connecting part 142, and the extending direction of the shock absorber is the direction of the shock absorber's axis P2. This allows the support arm 141 to form a certain gap with the front shock absorber 41, making it less likely to rub against or collide with the front shock absorber 41, thus reducing the impact on the front shock absorber 41.

[0047] See Figure 3 In some embodiments, the front fender 21 includes at least two detachable and interlocking baffles 211. Specifically, the different baffles 211 can be connected by snap-fit ​​or screws. Compared to a single unit, the modular design of the front fender 21 facilitates its installation and removal, improving maintainability.

[0048] See Figure 3 In some embodiments, the front mudguard 21 includes four baffles 211, namely a first baffle 2111, a second baffle 2112, a third baffle 2113, and a fourth baffle 2114. The first baffle 2111 and the second baffle 2112 are arranged opposite to each other in the front-rear direction of the electric two-wheeled vehicle 100. The third baffle 2113 is located on the left side of the front wheel 31 and covers the left side of the axle 311 of the front wheel 31. The fourth baffle 2114 is located on the right side of the front wheel 31 and covers the right side of the axle 311 of the front wheel 31.

[0049] Specifically, the first baffle 2111 partially covers the left and right sides of the front wheel 31, and partially covers the upper and front sides of the front wheel 31; the second baffle 2112 partially covers the left and right sides of the front wheel 31, and partially covers the upper and rear sides of the front wheel 31.

[0050] The first baffle plate 2111 and the second baffle plate 2112 can partially block the front and rear sides of the front wheel 31, while the third baffle plate 2113 and the fourth baffle plate 2114 can partially block the left and right sides of the front wheel 31. This reduces the amount of debris kicked up by the front wheel 31 from entering the axle 311 of the front wheel 31, thus improving driving safety. Furthermore, individual baffle plates 211 can be replaced, which helps reduce maintenance costs.

[0051] See Figure 1 and Figure 3 In some embodiments, when viewed from the left side of the electric two-wheeler 100, a portion of the projection of the third shield 2113 overlaps with a portion of the projection of one of the front shock absorbers 41. When viewed from the right side of the electric two-wheeler 100, a portion of the projection of the fourth shield 2114 overlaps with a portion of the projection of the other front shock absorber 41.

[0052] The third baffle plate 2113 and the fourth baffle plate 2114 cover positions corresponding to one of the front shock absorbers 41. When maintenance or replacement is required, simply remove the third baffle plate 2113 or the fourth baffle plate 2114 to expose the corresponding front shock absorber 41, which facilitates the maintenance and replacement of the front shock absorber 41.

[0053] See Figure 3 In some embodiments, the end of the support arm 141 away from the lower connecting plate 42 is fixed to the left and right sides of the first baffle plate 2111 by the support arm connector 143.

[0054] See Figure 3 and Figure 5 In some embodiments, the frame 10 includes a second front support member 15, which is connected to the lower connecting plate 42 and supports the rear of the front fender 21. For example, the second front support member 15 supports the second shield 2112. The second front support member 15 provides support for the rear of the front fender 21 and works in conjunction with the two support arms 141 to support the left and right sides and the rear of the front fender 21, thereby improving the overall structural strength of the front fender 21.

[0055] The method of fixing the second front support member 15 to the lower connecting plate 42 may include, but is not limited to, welding, bolting, screwing, and snap-fit ​​fixing. For example, the second front support member 15 may be detachably connected to the lower connecting plate 42 by means of bolts and nuts.

[0056] In some embodiments, the second front support 15 is a sheet metal part, which has good structural strength compared to plastic parts.

[0057] In addition, those skilled in the art may make other changes within this application. Of course, all such changes made in accordance with this application should be included within the scope disclosed in this application.
