[0001] The utility model relates to the technical field of battery compartments for electric vehicles, in particular to a battery compartment assembly for a two-wheeled electric vehicle. Background Art

[0002] Two-wheeled electric vehicles are a type of personal transportation vehicle powered by electricity, usually including electric bicycles, electric motorcycles and electric mopeds. They are composed of electric motors, batteries, controllers, display instrument systems and other components, and can provide a zero-emission clean travel mode, suitable for a variety of purposes such as urban commuting, short-distance travel and express delivery. Two-wheeled electric vehicles are designed to provide convenient, economical and environmentally friendly transportation solutions. With the development of technology, modern two-wheeled electric vehicles have significantly improved in terms of endurance, intelligence level and user experience.

[0003] At present, in order to increase battery capacity and improve driving range, the battery shell of electric two-wheeled vehicles tends to be larger, and higher requirements are placed on the size of the entire vehicle. Due to the compact layout, most electric two-wheeled vehicles can only place the battery in the seat bucket, sacrificing most of the storage space and destroying the center of gravity layout of the entire vehicle, which has a great impact on the commercial quality. If the battery is placed in the middle pedal position, a complex opening structure needs to be placed, which has general stability and cumbersome operation. In addition, since the battery needs to be pressed down by external force to prevent jumping, the battery cover is deformed upward by the reaction force, resulting in cracks in the decorative panel, affecting the appearance of the entire vehicle. At the same time, the large width of the vehicle will affect driving comfort. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 and 7 As shown, the utility model provides a battery compartment assembly for a two-wheeled electric vehicle, comprising a front decorative panel 1 and a rear decorative panel 13 mounted on an electric vehicle frame 2, wherein the front decorative panel 1 is located in front of the rear decorative panel 13, the front decorative panel 1 is mounted at the front of the two-wheeled electric vehicle, and the rear decorative panel 13 is mounted at the body of the two-wheeled electric vehicle;

[0028] An upper battery compartment 5 is provided below the front decorative panel 1 and the rear decorative panel 13, a lower battery compartment 7 is fixed to the bottom of the upper battery compartment 5, two pairs of battery support bars 8 are fixed to the outer wall of the lower battery compartment 7, the battery support bars 8 are fixed to the electric vehicle frame 2, and are used to reinforce and fix the lower battery compartment 7 to the electric vehicle frame 2 to improve the firmness of the structure, a battery compartment cover lining plate 15 is rotatably connected to the front side of the rear decorative panel 13 through a latch B12, a battery compartment cover 14 is fixed to the top of the battery compartment cover lining plate 15, and a lock hook 3 is fixed to the middle of the bottom of the battery compartment cover lining plate 15 close to the front decorative panel 1;

[0029] Moreover, a battery pressure strip 16 is rotatably connected to one side of the top of the upper battery compartment 5 near the rear decorative plate 13 through a latch A11, and the latch A11 and the latch B12 are staggered in the radial direction. The battery pressure strip 16 is located at the bottom of the battery compartment cover inner lining plate 15, as shown in FIG. Figure 5 As shown, a rubber rope 151 is fixed between the battery pressure strip 16 and the battery compartment cover lining plate 15, so that the opened battery compartment cover lining plate 15 drives the battery pressure strip 16 to be opened synchronously through the rubber rope 151; a lock plate 4 is provided on the top of the upper battery compartment 5, and the lock plate 4 is fixed on the electric vehicle frame 2, and is used to lock the lock hook 3 to fix the position of the battery compartment cover 14, the battery compartment cover lining plate 15 and the battery pressure strip 16 when the battery compartment cover 14, the battery compartment cover lining plate 15 and the battery pressure strip 16 are covered on the upper battery compartment 5.

[0030] like Figure 2 and 3 As shown, the lock plate 4 is composed of an upper lock tongue 41 and a lower lock tongue 42. When locked, as shown in FIG. Figure 2 As shown, the upper lock tongue 41 hooks the lock hook 3, and the lower lock tongue 42 presses the battery pressure strip 16, and the battery compartment cover 14 and the battery pressure strip 16 are fixed at the same time; because there is a sufficient gap between the battery pressure strip 16 and the battery compartment cover inner lining plate 15, the deformation caused by the reaction force when the battery pressure strip presses the battery A6 and the battery B10 will not affect the battery compartment cover 14 and the battery compartment cover inner lining plate 15, and no crack will be generated in appearance. Figure 3As shown, the upper locking tongue 41 and the lower locking tongue 42 simultaneously release the limiting effect on the battery compartment cover 14 and the battery pressure strip 16, and the battery compartment cover 14 pops up; when the user opens the battery compartment cover 14 and makes a circular motion along the axis of the latch B12, the rubber rope 151 drives the battery pressure strip 16 to make a circular motion along the axis of the latch A11, thereby realizing the synchronous opening of the battery compartment cover 14 and the battery pressure strip 16. At the same time, since the battery compartment cover 14 and the battery pressure strip 16 do not share a common rotation axis, the latch A11 and the latch B12 are staggered in the radial space, which effectively utilizes the redundant space and suppresses the enlargement of the body width of the two-wheeled electric vehicle.

[0031] like Figure 5-7 As shown, when opened to the extreme position, the battery compartment cover 14 and the battery pressure strip 16 interfere with the rear decorative panel 13, and at the same time, the center of gravity of the battery compartment cover 14 and the battery pressure strip 16 all exceed the 90° normal, so that the two can be positioned without being subjected to external force; because a magnet 161 is fixed to the side of the battery pressure strip 16 close to the battery compartment cover inner lining plate 15, and an iron gasket 152 is fixed to the side of the battery compartment cover inner lining plate 15 close to the battery pressure strip 16, so when the battery compartment cover 14 and the battery pressure strip 16 are rotated to the above-mentioned position, the magnet 161 fixed on the battery pressure strip 16 and the iron gasket 152 fixed on the battery compartment cover inner lining plate 15 are attracted to each other, thereby preventing the two from moving relative to each other in the open state.

[0032] like Figure 1 and 5 As shown, after the opening action is completed, the battery B10 can be directly extracted upwards and taken out. In order to facilitate the removal of the battery A6, a battery partition 9 that can rotate is provided in the middle of the lower battery compartment 7. The battery partition 9 divides the interior of the lower battery compartment 7 into two independent cavities. The battery A6 and the battery B10 are placed in the two cavities respectively. Moreover, the battery A6 in the utility model can rotate with the battery partition 9. The specific operation is: pull the battery A6, and the battery A6 rotates around the battery partition 9 and the lower battery compartment under the limiting action of the battery partition 9. 7 is rotated clockwise to the extreme position, at which time the battery separator 9 and the limit groove of the lower battery compartment 7 fit each other, and the center of gravity of the battery A6 at this angle exceeds the 90-degree axis, so the battery A6 will not return counterclockwise to the original upright state; the user can extract the battery A6 obliquely upward along the direction of the battery separator 9; during this operation, the user only needs to complete the upward extraction action of the battery, and there is no need to move the battery horizontally. The battery A6 and the battery B10 will not generate excess friction with the lower battery compartment 7, making the user operation more convenient.

[0033] When putting the battery back, the user first places the battery A6 in an inclined direction along the battery partition 9, pushes the battery A6 counterclockwise to drive the battery partition 9 back to a vertical state; then places the battery B10 vertically into the lower battery compartment 7; at this time, the user can directly push the battery compartment cover 14 in the opposite direction, and under the influence of gravity, the battery compartment cover 14 will drive the other moving parts to make a counterclockwise circular motion under the action of gravity and thrust until the upper lock tongue 41 hooks the lock hook 3 and the lower lock tongue 42 presses the battery pressure strip 16, completing the locking, and no other operations are required. At this time, the battery pressure strip 16 is bent and deformed upward by the reaction force of the battery A6 and the battery B10, and all the components in the lower battery compartment 7 are fixed and limited; during driving, the battery A6 and the battery B10 will not jump upward when subjected to impact force, and the lock plate 4 separates and fixes the battery compartment cover 15 and the battery pressure strip 16, thereby preventing the battery compartment cover 15 from being affected by the deformation of the battery pressure strip 16; in addition, since the battery compartment cover 15 and the battery pressure strip 16 have their own independent rotating shafts and locking tongues, the battery compartment cover 15 will not be unable to be opened due to damage to the rotating shaft or the locking tongue, which greatly reduces the failure rate of the entire mechanism.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
