[0074] To better understand the structure and effects of this utility model, the following description is provided in conjunction with the accompanying drawings.

[0075] First, please refer to Figure 2 As shown, the battery structure of the electric motorcycle of this utility model is illustrated. The electric vehicle 2 of this utility model is exemplified by an electric straddle-type vehicle. The electric vehicle 2 has a frame unit 3, with a head tube 31 at the front. A steering mechanism 311 is located above the head tube 31, and a front fork unit (front shock absorber) 32 is connected below the steering mechanism 311. A front wheel FW is pivotally mounted below the front fork unit 32. A main tube 33 extends from the head tube 31 towards the rear and downwards of the vehicle body from the frame unit 3. A pair of side frame tubes 34 extend from the main tube 33 towards the rear of the vehicle body. Each side frame tube 34 includes a pair of footrest tubes 341 adjacent to the main tube 33, a pair of riser sections 342 extending upwards from the footrest tubes 341 towards the rear of the vehicle body, and a... The vehicle has a pair of left and right rear frame sections 343; a horizontal tube 344 is provided between the riser section 342 and the foot pedal section 341, and a rear wheel RW is provided at the lower rear of the rear frame section 343; a drive motor 4, which serves as a power source, is pivotally provided at the rear of the riser section 342 of the side frame tube 34, and the drive motor 4 drives the rear wheel RW through a transmission member 41, thereby propelling the electric vehicle 2 forward; a controller 5 that can control the operation of the drive motor 4 is provided on the rear frame section 343 of the side frame tube 34, and a battery 7 that provides the power source required for the operation of the drive motor 4 is installed between the riser sections 342 of the side frame tube 34; a seat section 35 is provided on the rear frame section 343 behind the steering mechanism 311 and above the rear wheel RW, and the seat section 35 is spaced apart from the steering mechanism 311.

[0076] The electric vehicle 2 is provided with a body cover unit 6 on its outer periphery. The body cover unit 6 has a front cover 61 covering the steering mechanism 311, a front panel 62 located below the front cover 61 and covering the front of the vehicle body, and a knee cover 63 located behind the front panel 62. A foot pedal 64 is located below the steering mechanism 311 and the seat 35. A bottom cover 641 is provided below the foot pedal 64. The electric vehicle 2 has side body covers 65 on both sides below the seat 35. A central body cover 66 is provided below the front of the seat 35. A storage box 36 is provided below the seat 35. The top of the storage box 36 is covered by the seat 35.

[0077] like Figure 2 , 3 As shown, the electric vehicle 2 has a battery 7 installed in front of the storage compartment 36 or below the foot pedal 64. This case illustrates the example of installing the battery 7 in front of the storage compartment 36 and below the seat 35. The battery 7 has a housing 71, a top cover 72 on top of the housing 71, and a bottom cover 73 on bottom of the housing 71. The battery 7 is electrically connected to the drive motor 4, thereby enabling the drive motor 4 to obtain the power source required for operation.

[0078] like Figure 3 , 4 As shown in Figure 5, the housing 71 is a rectangular barrel, and a battery cell 8 is provided inside the housing 71. The battery cell 8 can store electrical energy. The bottom end of the battery cell 8 is provided with a power output terminal 81. In the implementation of this utility model, the housing 71 and the battery cell 8 can be integrally formed into an integrated unit.

[0079] like Figure 3 , 4 As shown in Figure 5, the top cover 72 is located at the upper end of the housing 71, thereby sealing the upper end of the housing 71. The top cover 72 has a recessed portion 721 in the center. The top cover 72 is provided with at least one vent hole 722, which passes through the top cover 72 and connects to the interior of the housing 71. On both sides of the vent hole 722, there are venting channels 723 that are recessed and connected to the vent hole 722. The venting channels 723 on both sides connect the outer side of the top cover 72 and the recessed portion 721. A one-way venting valve 9 is installed in the vent hole 722, so that the heat generated by the battery cell 8 inside the housing 71 during operation can be discharged from the battery 7 through the one-way venting valve 9 upwards and through the venting channel 723, thereby avoiding the accumulation of too much heat inside the battery 7 and affecting the service life of the battery cell 8.

[0080] like Figure 3 , 4As shown in Figure 5, a handle cover 74 is provided at the upper end of the top cover 72. The handle cover 74 is engaged with the top cover 72 by a locking or hook mechanism, with hook mechanism A being used as an example in the figure. A decorative cover portion 741 is provided around the handle cover 74, which is used to lock the handle cover 74 to the top edge of the top cover 72. The decorative cover portion 741 is provided with a pressing mechanism 742 corresponding to the vent 722 of the top cover 72. The pressing mechanism 742 can press against the one-way vent valve 9, thereby enabling the one-way vent valve 9 to achieve a stable positioning effect. When the pressing mechanism 742 of the decorative cover portion 741 presses against the one-way vent valve 9, the decorative cover portion 741 can cover the one-way vent valve 9. Since the battery cell 8 inside the housing 71 is operating... The heat generated during operation can be discharged from the battery 7 through the one-way vent valve 9 and the venting channel 723. Therefore, the one-way vent valve 9 is not visible when viewed from above the battery 7. Thus, it does not affect the discharge of heat generated by the battery cell 8 during operation, and it can also enhance the overall appearance and commercial value of the battery 7. The handle cover 74 is provided with a handle 743 that spans both sides of the cover portion 741 and protrudes slightly upwards towards the battery 7 in an arc shape. More specifically, the handle 743 spans the recessed portion 721 of the top cover 72. The space formed by the recessed portion 721 and the upward protrusion of the handle 743 allows the driver to easily hold the handle 743 to remove the battery 7 from the electric motorcycle 2.

[0081] like Figure 3 , 6As shown in Figures 7 and 8, the bottom cover 73 is locked onto the bottom end of the housing 71, thereby sealing the bottom end of the housing 71. Near the center of the bottom cover 73 is a power input / output port 731, which allows the power input / output terminal 81 of the battery cell 8 to be installed. Through this port 731, external power is input into the battery cell 8 for storage, and the stored power can also be output to supply the power required for the operation of the drive motor 4 of the electric motorcycle 2. The bottom cover 73 is used to install the power input / output port... A pair of engaging mechanisms 732 are provided on both sides of the connector 731. These engaging mechanisms 732 are recessed into the bottom cover 73, providing a stable locking position when the battery 7 is installed on the electric motorcycle 2. The bottom cover 73 has at least one vent 733 that penetrates the housing 71. The vent 733 extends through the bottom cover 73 and connects to the interior of the housing 71. A venting channel 734 is recessed on one side of the vent 733 and connects to the engaging mechanism 732. The vent 733 can also be fitted with a one-way vent. The air valve 9 is installed so that some of the heat generated by the battery cell 8 inside the housing 71 during operation can be discharged through the vent 733 and the one-way vent valve 9, then downwards through the vent channel 734 into the locking mechanism 732, and finally out of the battery 7. This prevents excessive heat buildup inside the battery 7 from affecting the lifespan of the battery cell 8. The bottom cover 73 has a protective pad 735 on the outer side relative to the housing 71. This protective pad 735 is implemented with a soft pad body, thereby reducing friction or collision between the bottom cover 73 and the vehicle body components. The protective pad 735 has a through hole 7. 36. A stop mechanism 737 and a pair of through holes 738 are provided. The through hole 736 is correspondingly provided with the power input / output port 731, so that the power input / output port 731 is exposed in the through hole 736. The stop mechanism 737 is correspondingly provided with the vent hole 733 and the one-way vent valve 9, so that the stop mechanism 737 can stop the one-way vent valve 9, thereby enabling the one-way vent valve 9 to obtain a stable positioning effect. The through hole 738 is correspondingly provided with the locking mechanism 732, that is, the locking mechanism 732 is exposed in the through hole 738, so as not to hinder the locking mechanism 732 from performing the locking action.

[0082] like Figure 2 , 3As shown in Figures 4, 5, 6, 7, and 8, this utility model uses the above-described structure to cover the outer end of the one-way vent valve 9 of the battery 7 by the external components of the battery 7 (the decorative cover portion 741 of the handle cover 74 and the protective pad 735). That is, the upper part of the battery 7 is provided with a vent hole 722 and a venting connecting channel 723, and the one-way vent valve 9 is installed on the vent hole 722. The lower part of the battery 7 is provided with a vent hole 733 and a venting connecting channel 734, and the one-way vent valve 9 is installed on the vent hole 733. The one-way vent valve 9 located above the battery 7 is covered by the decorative cover portion 741 of the handle cover 74, and the one-way vent valve 9 located below the battery 7 is covered by the protective pad 735. In this way, on the one hand, the heat generated by the battery cell 8 during operation is not affected, and on the other hand, the overall appearance and commercial value of the battery 7 are improved.

[0083] The main feature of this invention is that the battery 7 has a housing 71, a top cover 72 located above the housing 71, and a bottom cover 73 located below the housing 71. The housing 71 contains a battery cell 8. The battery 7 is provided with vent holes 722 and 733 for venting internal heat. The vent holes 722 and 733 are connected to venting channels 723 and 734. One-way venting valves 9 are installed on the vent holes 722 and 733. The outer end of the one-way venting valves 9 is covered by the outer components of the battery 7. In this way, the venting of heat generated by the battery cell 8 during operation is not affected, and the overall appearance and commercial value of the battery 7 are improved.

[0084] In summary, the present invention, through the above-described structure, can improve upon known deficiencies and achieve the claimed purpose, and has indeed improved upon existing technologies, thus possessing novelty, practicality, and inventiveness.
