Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle technology, and specifically to an electric motorcycle battery mounting structure. Background Technology

[0002] Electric motorcycles, also known as electric motor motorcycles, primarily use batteries as their power source and convert electrical energy into mechanical energy through an electric motor.

[0003] In existing technologies, electric motorcycle batteries are usually installed under the seat or in a pre-reserved battery slot inside the frame. Regardless of the installation method, the size of the battery is limited by the preset installation location, making it impossible to replace with a larger capacity battery. This results in a single battery configuration option for electric motorcycles, and users cannot flexibly replace batteries of different capacities later, which greatly limits the usage scenarios of motorcycles. Utility Model Content

[0004] In view of this, the present invention provides a battery mounting structure for electric motorcycles, which can replace batteries of different capacities as needed.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An electric motorcycle battery mounting structure includes a frame body and a battery, characterized in that the battery is fixedly mounted on the lower front side of the frame body in a suspended position.

[0007] By adopting the above structure and suspending the battery in mid-air, the installation space for the battery is no longer limited, thus allowing for the replacement of batteries with different capacities as needed.

[0008] Preferably, the battery is a rectangular block structure and is fixedly installed at an angle on the lower front side of the vehicle frame body.

[0009] Preferably, the battery is secured to the lower front side of the vehicle frame body by bolts extending along the width of the frame body. This structure simplifies the installation of the battery to the vehicle frame body.

[0010] Preferably, the lower front side of the frame body has two inclined support tubes, and the upper side of the battery has an upwardly protruding mounting boss located between the two support tubes. The mounting boss and the two support tubes are fixedly connected by threaded fasteners. This structure allows for a tighter connection between the battery and the frame body, thus ensuring the strength of the connection.

[0011] Preferably, the mounting boss has a central hole extending along the width of the battery, and both support tubes have mounting holes coaxially opposite the central hole. The threaded fastener includes a bolt and a nut. The bolt passes through the central hole and the mounting holes of the two support tubes, with the bolt head located in the mounting hole of one support tube and the nut located in the mounting hole of the other support tube. This structure ensures a stable connection between the battery and the vehicle frame body through the threaded fastener.

[0012] Preferably, the width of the mounting boss is smaller than the width of the battery, so that both ends of the battery abut against the lower side of the support tube. This structure further ensures a tighter fit between the battery and the vehicle frame.

[0013] Preferably, the battery has two sets of mounting bosses on its upper side, and both sets of mounting bosses are fixedly connected to the two support tubes by threaded fasteners. With this structure, the battery is more stably mounted on the vehicle frame body using two sets of threaded fasteners.

[0014] Preferably, the frame body has a hollow structure in the area corresponding to the upper side of the battery. This structure facilitates better heat dissipation from the battery.

[0015] Preferably, the frame body has a rearwardly extending seat support frame in the middle, and a reinforcing rod connects the rear end of the seat support frame to the rear end of the frame body. The frame body, seat support frame, and reinforcing rod form a triangular mounting area, and a controller associated with the battery is installed within this triangular mounting area. This structure further avoids affecting battery heat dissipation and also prevents the controller from overheating and malfunctioning.

[0016] Preferably, a motor is mounted at the bottom of the vehicle frame, near the lower end of the battery. Protective shells are provided on the lower side of both the battery and the motor. This structure, with its protective shells, provides support and protection for the battery and motor, preventing deformation of the threaded fasteners that could affect the disassembly and replacement of batteries of different capacities.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The electric motorcycle battery mounting structure provided by this utility model allows the battery to be installed in a suspended manner, thus freeing the battery installation space from being limited. Different capacity batteries can be used during the production of electric motorcycles, or users can flexibly replace batteries of different capacities or shapes during later use, greatly improving the flexibility of electric motorcycle production and use.

[0019] 2. The battery can be fixedly installed under the frame body using two sets of threaded fasteners, making the overall installation method very simple and stable.

[0020] 3. The controller is installed in a location away from the battery, which facilitates better heat dissipation from the battery and also prevents the controller from overheating and malfunctioning.

[0021] 4. The bottom of the frame body is equipped with a protective shell, which can support and protect the battery, and also prevent the screw from being deformed by stress after replacing with a large-capacity battery. Attached Figure Description

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, an electric motorcycle battery mounting structure includes a frame body 1 and a battery 2, wherein the battery 2 is fixedly mounted on the lower front side of the frame body 1 in a suspended manner. In this embodiment, the battery 2 is a rectangular block structure and is fixedly mounted on the lower front side of the frame body 1 in an inclined manner.

[0030] This design, by suspending the battery 2 in mid-air, eliminates the limitation on the installation space of the battery 2. Different capacity batteries 2 can be used during the production of electric motorcycles, or users can flexibly replace the batteries 2 with different capacities or shapes during later use, which greatly improves the flexibility of electric motorcycle production and use.

[0031] In this embodiment, the battery 2 is fastened to the lower front side of the frame body 1 by bolts 3 extending along the width direction of the frame body 1.

[0032] Specifically, such as Figures 2 to 5As shown, there are two inclined support tubes 1a on the lower front side of the frame body 1, and an upwardly protruding mounting boss 2a is formed on the upper side of the battery 2. The mounting boss 2a is located between the two support tubes 1a, and the mounting boss 2a is fixedly connected to the two support tubes 1a by threaded fasteners. This design allows for a tighter and more secure connection between the battery 2 and the frame body 1.

[0033] Furthermore, such as Figures 3 to 5 As shown, the mounting boss 2a has a central hole 2b extending through the width of the battery 2. Both support tubes 1a have mounting holes 1b coaxially opposite the central hole 2b. The threaded fasteners include a bolt 3 and a nut 7. The bolt 3 passes through the central hole 2b and the mounting holes 1b of both support tubes 1a, with the bolt head located in one of the mounting holes 1b of the support tube 1a, and the nut 7 located in the mounting hole 1a of the other support tube 1a. This design, through the threaded engagement of the bolt 3 and nut 7, allows the battery 2 to be stably mounted under the frame body 1, and also simplifies the connection between the battery 2 and the frame body 1.

[0034] In this embodiment, the width of the mounting boss 2a is smaller than the width of the battery 2, so that both ends of the battery 2 can abut against the lower side of the support tube 1a, thereby making the battery 2 and the frame body 1 more tightly and securely installed.

[0035] like Figure 5 As shown, in this embodiment, two sets of mounting bosses 2a are formed on the upper side of the battery 2, and both sets of mounting bosses 2a are fixedly connected to the two support tubes 1a by threaded fasteners. With this design, the battery 2 can be more securely mounted on the vehicle frame body 1 by the two sets of threaded fasteners.

[0036] like Figure 2 and Figure 3 As shown, a rubber plug 8 is fitted on the outer end of each mounting hole 1b. The rubber plug 8 ensures that the bolt 3 and nut 7 will not fall off after they become loose and separate, effectively preventing the battery 2 from separating from the frame body 1 during the use of the electric motorcycle.

[0037] like Figure 2 As shown, the upper part of the frame body 1 is a hollow area corresponding to the battery 2. This design facilitates heat dissipation of the battery 2.

[0038] like Figure 2 and Figure 6As shown, the frame body 1 has a rearwardly extending seat support frame 1c in the middle. The top of the seat support frame 1c is used to fix the motorcycle seat. A reinforcing rod 1d connects the rear end of the seat support frame 1c to the rear end of the frame body 1. The frame body 1, seat support frame 1c, and reinforcing rod 1d form a triangular mounting area. A controller 4 associated with the battery 2 is installed within the triangular mounting area. This design, by installing the controller 4 away from the battery 2, facilitates better heat dissipation for the battery 2 and also avoids overheating and overload of the controller 4, thus preventing malfunction.

[0039] For example Figure 2 As shown, a motor 5 is mounted at the bottom of the frame body 1, near the lower end of the battery 2. A protective shell 6 is installed on the lower side of both the battery 2 and the motor 5. This design, through the protective shell 6, provides support and protection for the battery 2 and the motor 5. It also prevents the bolts 3 from deforming due to stress after replacing the battery 2 with a larger capacity one, thus avoiding interference with the normal disassembly and replacement of the battery 2. When replacing the battery 2 with one of different capacities, only the corresponding protective shell 6 needs to be replaced.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
