Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an electric motorcycle. Background Technology

[0002] Electric motorcycles are becoming increasingly popular among consumers as a type of vehicle. They are mainly used for personal travel, leisure, and other purposes; especially in some mountainous cities, electric motorcycles are a preferred choice for commuting and carrying goods due to their strong climbing ability and load-bearing capacity.

[0003] Existing electric motorcycles have limited space due to the constraints of their frame structure; and because the weight of the power battery is concentrated in one part of the vehicle, there are also high requirements for the rigidity of the frame.

[0004] The existing battery compartment is located on the vehicle frame, and the battery is located inside the battery compartment. Due to the limited load-bearing capacity of the vehicle frame, the placement of the battery is also limited. Utility Model Content

[0005] In view of this, this application provides an electric motorcycle with a lighter battery compartment, which allows the frame to support a larger capacity battery.

[0006] An embodiment of this application provides an electric motorcycle, including: a frame, a body panel, a running gear system, and a power system. The frame includes a front frame, a chassis frame, and a rear frame connected in sequence. The body panel at least partially covers one of the front frame, chassis frame, and rear frame. The running gear system is at least partially disposed below the front frame and rear frame. The power system includes a power battery and a drive motor. The power battery is electrically connected to the drive motor and supplies power to the drive motor to drive the running gear system. The power system also includes a battery compartment supported by the chassis frame. The battery compartment includes a front compartment and a rear compartment, which together form an accommodating space. The power battery is installed in the accommodating space. The front compartment is a plastic part located at the front of the chassis frame, and the rear compartment is a sheet metal part located at the rear of the chassis frame.

[0007] Furthermore, the front compartment and the rear compartment are detachably connected.

[0008] Furthermore, the front compartment has a front connecting portion, and the rear compartment includes a first support section, a second support section, and a third support section. The first support section is supported below the front connecting portion, and the second support section and the third support section are respectively located on both sides of the first support section along the width direction of the vehicle frame, and cover the outer surfaces of both sides of the front connecting portion in the width direction.

[0009] Furthermore, the first support segment, the second support segment, and the third support segment together form a connector, and the front connecting part is inserted into the connector along the front-rear direction of the electric motorcycle.

[0010] Furthermore, the rear compartment is welded to the underframe and / or the rear frame.

[0011] Furthermore, the underframe includes several battery compartment support frames, which are attached to the underside of the underframe. The battery compartment support frames and the underframe together form a battery compartment mounting area. The battery compartment is disposed in the battery compartment mounting area, and the battery compartment support frames support the battery compartment.

[0012] Furthermore, the battery compartment support frame includes a first connecting section, a second connecting section, and a third connecting section in sequence. The first connecting section and the third connecting section are attached to both sides of the chassis frame in the width direction, and the second connecting section is supported under the battery compartment. The first connecting section, the second connecting section, and the third connecting section face the surface of the battery compartment and are in contact with the outer surface of the battery compartment.

[0013] Furthermore, the body panel also includes a foot pedal, which at least partially covers the front compartment and the rear compartment and partially encloses the accommodating space.

[0014] Furthermore, the body panel includes a flange, which is connected to both sides of the front compartment in the width direction and extends along the front-rear direction of the electric motorcycle, and the chassis portion is supported by the flange.

[0015] Furthermore, multiple power batteries are provided, and the multiple power batteries are distributed sequentially along the front-rear direction of the electric motorcycle. The body panel includes a seat assembly, which is mounted on the rear frame. In the height direction of the motorcycle, the seat assembly is at least partially disposed above the battery compartment.

[0016] By dividing the battery compartment into a front and rear section, and using a plastic component for the front section, which is lighter than sheet metal, the overall weight of the battery compartment can be reduced. Without changing the load-bearing capacity of the chassis, reducing the weight of the battery compartment provides more space for battery installation, allowing for the installation of larger capacity batteries.

[0025] 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.

[0026] like Figures 1 to 4 As shown, this application provides an electric motorcycle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, and a power system 15.

[0027] The body panel 12 includes a seat assembly 121 and at least partially covers the frame 11. The running system 13 is at least partially disposed under the frame 11 and includes front wheels 131 and rear wheels 132. A suspension system 14 connects the front wheels 131 and rear wheels 132 to the frame 11. A power system 15 is supported by the frame 11 and drives the running system 13.

[0028] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1The front, rear, left, right, top, and bottom sides are shown. In this embodiment, the front, rear, left, right, top, and bottom directions refer to the directions when the electric motorcycle 100 is on a horizontal plane. The front-rear direction refers to the length direction of the electric motorcycle 100 provided in this application, the left-right direction refers to the width direction of the electric motorcycle 100 provided in this application, and the up-down direction refers to the height direction of the electric motorcycle 100 provided in this application.

[0029] As one implementation method, such as Figure 2 As shown, the frame 11 includes a front frame 111, a chassis frame 112, and a rear frame 113 connected in sequence. A body panel 12 at least partially covers one of the front frame 111, chassis frame 112, and rear frame 113, and the running gear 13 is at least partially disposed below the front frame 111 and rear frame 113. Viewed along the length of the electric motorcycle 100, the frame 11 is substantially symmetrical from left to right.

[0030] In this embodiment, the front frame 111 includes a head tube 1111 and a main tube 1112. The main tube 1112 is connected to the middle of the head tube 1111, and the main tube 1112 is substantially perpendicular to the horizontal plane. There is an angle between the axis of the head tube 1111 and the axis of the main tube 1112. The front wheel 131 is connected to the head tube 1111 through a suspension system 14. Specifically, the suspension system 14 includes a front fork, and the front wheel 131 is connected to the head tube 1111 through the front fork.

[0031] It should be noted that the descriptions of "horizontal" and "vertical" in this embodiment are not strictly "horizontal" or "vertical" in the mathematical sense. They may have a certain angular error, for example, 5°~10°.

[0032] Please see Figure 2In this embodiment, the chassis frame 112 includes a main support 1121, a secondary support 1122, and a bottom support 1123. The main support 1121 is connected to both sides of the lower part of the front chassis 111. Exemplarily, the main support 1121 includes two main supports, left and right, with one end of each main support 1121 connected to the left and right sides of the lower part of the front chassis 111, respectively. Specifically, the main supports 1121 on both sides include a first pipe segment 1121a, a second pipe segment 1121b, and a third pipe segment 1121c connected in sequence; wherein, one end of the first pipe segment 1121a is connected to the lower side of the front chassis 111, and the other end of the first pipe segment 1121a extends substantially to the side of the electric motorcycle 100. One end of the second pipe segment 1121b is connected to the other end of the first pipe segment 1121a, and the other end of the second pipe segment 1121b extends substantially downwards from the electric motorcycle 100. One end of the third pipe segment 1121c is connected to the other end of the second pipe segment 1121b, and the other end of the third pipe segment 1121c extends substantially towards the rear of the electric motorcycle 100. The pipe segments are smoothly connected by curved bends.

[0033] One end of the sub-support 1122 is connected to the second pipe segment 1121b, and the other end of the sub-support 1122 is connected to the rear frame 113. For example, the connection point between the sub-support 1122 and the second pipe segment 1121b is located in the middle of the second pipe segment 1121b, and the connection point between the sub-support 1122 and the rear frame 113 is located at the lower part of the rear frame 113; the sub-support 1122 and the third pipe segment 1121c are arranged substantially parallel to each other.

[0034] The middle part of the bottom bracket 1123 is connected to the bottom of the front frame 111, and the two ends of the bottom bracket 1123 are respectively connected to the second pipe segment 1121b of the main bracket 1121 on the left and right sides. For example, the middle part of the bottom bracket 1123 is connected to the bottom of the main pipe 1112. The connection point between the bottom bracket 1123 and the second pipe segment 1121b and the connection point between the auxiliary bracket 1122 and the second pipe segment 1121b can be the same, or one connection point can be higher than the other connection point. This embodiment does not limit this.

[0035] In this embodiment, the bottom bracket 1123 is provided, which can effectively improve the rigidity of the frame 11 and enhance the stability of the vehicle handling.

[0036] As one implementation method, such as Figure 3 , Figure 4 and Figure 5 As shown, the power system 15 includes a power battery 151 and a battery compartment 152, with the power battery 151 installed in the battery compartment 152.

[0037] The chassis frame 112 also includes several battery compartment support frames 1124, which are attached to the underside of the chassis frame 112. Each battery compartment support frame 1124 includes a first connecting section 1124a, a second connecting section 1124b, and a third connecting section 1124c in sequence. The first connecting section 1124a and the third connecting section 1124c are attached to both sides of the chassis frame 112 in the width direction. The second connecting section 1124b is supported under the battery compartment 152. The first connecting section 1124a, the second connecting section 1124b, and the third connecting section 1124c face the surface of the battery compartment 152 and are in contact with the outer surface of the battery compartment 152.

[0038] The battery compartment 152 is supported by the second connecting section 1124b, and the position of the battery compartment 152 is restricted by the first connecting section 1124a and the third connecting section 1124c, thereby improving the installation stability of the battery compartment 152.

[0039] Please see Figure 3 , Figure 4 and Figure 5 In some embodiments, the battery compartment support frame 1124 consists of three strip-shaped support brackets. The two ends of the battery compartment support frame 1124 are respectively attached to the lower part of the third pipe section 1121c on the left and right sides, and the battery compartment support frame 1124 is distributed along the length direction of the electric motorcycle 100.

[0040] The battery compartment support frame 1124 and the chassis frame 112 together form a battery compartment mounting area, with the battery compartment support frame 1124 supporting the battery compartment 152. For example, a battery compartment mounting area is formed between the battery compartment support frame 1124, the main support 1121, and the secondary support 1122. The battery compartment 152 is disposed in the battery compartment mounting area and is fixedly connected to the battery compartment support frame 1124. For example, the battery compartment support frame 1124 is provided with a plurality of bolt holes, and the battery compartment 152 is fixed to the battery compartment support frame 1124 by bolt connection.

[0041] Furthermore, along the length of the electric motorcycle 100, at least the connection point between the main pipe 1112 and the base bracket 1123 is higher than the top end face of the power battery 151. This arrangement allows for the placement of a large-capacity battery within a compact space, enabling the vehicle to balance the high maneuverability of its short wheelbase with the long range of its large-capacity battery.

[0042] Please see Figure 3In one implementation, one end of the rear frame 113 is connected to the rear of the third pipe segment 1121c, and the other end of the rear frame 113 extends rearward and upward. In the width direction of the electric motorcycle 100, the lower part of the rear frame 113 overlaps with the battery compartment 152, meaning the rear frame 113 spans across both sides of the battery compartment 152. This arrangement further expands the battery installation space inside the vehicle, allowing for the installation of a large-capacity battery within a compact, short-wheelbase vehicle, balancing high operability and long range.

[0043] Please see Figure 1 and Figure 2 As one implementation, the rear frame 113 includes a seat bucket support frame 1131, and the seat assembly 121 includes a seat bucket 1211 and a seat cushion 1212. The seat bucket 1211 and the seat cushion 1212 are rotatably connected to form a storage space, and the seat bucket 1211 is mounted on the seat bucket support frame 1131.

[0044] In the height direction of the motorcycle, the seat assembly 121 is at least partially disposed above the battery compartment 152. Exemplarily, in the height direction of the motorcycle, the under-seat storage compartment 1211 is at least partially disposed above the battery compartment 152. With this arrangement, a large storage space for the under-seat storage compartment 1211 can be obtained in a compact installation space; exemplaryly, the under-seat storage compartment 1211 can accommodate at least one full-face helmet.

[0045] Please see Figure 2 In one embodiment, the rear frame 113 also includes a reinforcing bracket 1132, the bottom of which is connected to the main bracket 1121.

[0046] The frame 11 configuration in this embodiment, in a vehicle with a short wheelbase, compact design, and limited space, not only provides strong frame rigidity but also allows for the installation of a large-capacity battery and a large under-seat storage space 1211. It offers both flexible and stable handling performance as well as long range.

[0047] As one implementation method, such as Figure 3 , Figure 4 and Figure 5 As shown, the battery compartment 152 includes a front compartment 1521 and a rear compartment 1522, which are connected to form an accommodating space 1523. The power battery 151 is installed in the accommodating space 1523. The front compartment 1521 is a plastic part and is located at the front of the chassis 112, while the rear compartment 1522 is a sheet metal part and is located at the rear of the chassis 112.

[0048] By dividing the battery compartment 152 into a front compartment 1521 and a rear compartment 1522, and making the front compartment 1521 a plastic part, which is lighter than sheet metal parts, the overall weight of the battery compartment 152 can be reduced. While maintaining the same load-bearing capacity of the frame 11, reducing the weight of the battery compartment 152 provides more space for battery installation, allowing for the installation of larger capacity batteries.

[0049] In some embodiments, the front compartment 1521 and the rear compartment 1522 are detachably connected. This detachable connection facilitates the installation of the front compartment 1521 and the rear compartment 1522 within the battery compartment mounting area. Compared to a fixed connection, this embodiment allows for a smaller installation space for the battery compartment 152 when designing the electric motorcycle 100, thus improving the structural compactness of the electric motorcycle 100.

[0050] Please see Figure 3 , Figure 4 and Figure 5 In some embodiments, the front compartment 1521 has a front connecting portion 1521a, which is generally U-shaped. The rear compartment 1522 includes a first support section 1522a, a second support section 1522b, and a second support section 1522c. The first support section 1522a is supported below the front connecting portion 1521a. The second support sections 1522b and 1522c are located on both sides of the first support section 1522a along the width direction of the frame 11 and cover the outer surfaces of both sides of the front connecting portion 1521a in the width direction. For example, the first support section 1522a extends along the width direction of the electric motorcycle 100, and the second support sections 1522b and 1522c extend along the height direction of the electric motorcycle 100.

[0051] The first support section 1522a can provide support for the front connecting part 1521a in the height direction of the electric motorcycle 100, and the second support sections 1522b and 1522c provide a limit for the front connecting part 1521a in the width direction of the electric motorcycle 100, restricting the front connecting part 1521a from moving relative to the front compartment 1521 in the width direction of the electric motorcycle 100, thereby realizing the connection between the front compartment 1521 and the rear compartment 1522.

[0052] Please see Figure 5 and Figure 6 In some embodiments, the first support section 1522a, the second support section 1522b, and the second support section 1522c together form an insertion interface, and the front connecting part 1521a is inserted into the insertion interface along the front-rear direction of the electric motorcycle 100. This arrangement facilitates the quick assembly and disassembly of the front connecting part 1521a and the front compartment 1521.

[0053] For example, the connector is flared, which facilitates the insertion of the front connector 1521a into the connector. Furthermore, after the front connector 1521a is inserted into the connector, the inner surface of the front compartment 1521 is flush with the inner surface of the rear compartment 1522, which facilitates the stable installation of the power battery 151.

[0054] In some embodiments, the rear compartment 1522 is welded to the underframe 112 and / or the rear frame 113 to improve the installation stability of the rear compartment 1522 on the frame 11.

[0055] Please see Figure 1 In some embodiments, the body panel 12 further includes a foot pedal 122, which covers the front compartment 1521 and the rear compartment 1522 and partially covers the accommodating space 1523. The foot pedal 122 not only cooperates with the front compartment 1521 and the rear compartment 1522 to form a space for accommodating the power battery 151, but also provides a place for the driver's feet. The foot pedal 122, together with the front compartment 1521 and the rear compartment 1522, separates the external environment from the power battery 151, thereby effectively blocking mud and water.

[0056] Please see Figure 4 In some embodiments, the body panel 12 includes a flange 123, which is connected to both sides of the front compartment 1521 in the width direction and extends along the longitudinal direction of the electric motorcycle 100. The underframe 112 is partially supported by the flange 123. Exemplarily, a sub-support 1122 is supported under the flange 123. The side of the flange 123 facing the sub-support 1122 has an opening. During the installation of the front compartment 1521 in the battery compartment mounting area, the sub-support 1122 enters the flange 123 through the opening, such that the flange 123 covers part of the outer surface of the sub-support 1122 and is supported by the sub-support 1122.

[0057] Please see Figure 4 In some embodiments, multiple power batteries 151 are provided, and the multiple power batteries 151 are distributed sequentially along the front-rear direction of the electric motorcycle 100. For example, two power batteries 151 are provided. By providing multiple power batteries 151, the range of the electric motorcycle 100 is improved.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
