Detailed Description

In order to make the technical solution of the present invention better understood, the technical solution of the present invention in the specific embodiment will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1, an electric scooter 100 includes a frame 11, a suspension system 12, a traveling system 13, and a three-electric system 14. The running system 13 is connected with the vehicle frame 11 through the suspension system 12, and the three-electric system 14 is at least partially arranged on the vehicle frame 11. Specifically, the frame 11 includes a mounting frame 111, a supporting frame 112 and a fixing bracket 113, the mounting frame 111, the supporting frame 112 and the fixing bracket 113 are integrally formed, and the mounting frame 111 and the fixing bracket 113 are respectively disposed at the front side and the rear side of the supporting frame 112. The mounting brackets 111 are substantially disposed in the up-down direction of the electric scooter 100, and the supporting brackets 112 are substantially disposed in the front-rear direction of the electric scooter 100. The traveling system 13 includes front wheels 131 and rear wheels 132, the front wheels 131 being connected to the mounting frame 111 through the suspension system 12, and the rear wheels 132 being connected to the fixed bracket 113 through the suspension system 12. The three-electric system 14 comprises a power battery 141, wherein the power battery 141 is at least partially arranged on the supporting frame 112, and the power battery 141 is in transmission connection with the rear wheel 132. In order to clearly illustrate the technical scheme of the present application, the upper side, the lower side, the left side, the right side, the front side and the rear side shown in fig. 1 are also defined.

As shown in fig. 2, specifically, on a symmetry plane 101 perpendicular to the left-right direction of the electric scooter 100, the electric scooter 100 is substantially symmetrically disposed about the symmetry plane 101. When the power battery 141 is at least partially disposed on the supporting frame 112, the power battery 141 is substantially disposed symmetrically with respect to the symmetry plane 101. The support frame 112 is provided with pedals 114, and the pedals 114 are respectively arranged on the left and right sides of the power battery 141.

As shown in fig. 2 and 3, further, the power battery 141 can extend beyond the end surface of the step plate 114 and toward the upper side of the step plate 114, and the power battery 141 is disposed in a standing transverse manner. The number of the power batteries 141 is at least two, and the adjacent power batteries 141 are arranged in a front-back distribution manner, so that the space occupied by the power batteries 141 in the front-back direction of the electric scooter 100 can be reduced to the maximum extent while the center of gravity of the electric scooter 100 is improved. Thereby making the spatial layout of the electric scooter 100 more compact.

Specifically, since the power battery 141 is substantially cubic, when the power battery 141 is disposed in a standing transverse manner, the shortest side of the power battery 141 is substantially parallel to the front-back direction of the electric scooter 100, so as to reduce the total length of at least two power batteries 141 distributed along the front-back direction, thereby making the entire vehicle layout of the electric scooter 100 more compact. And the longest side of the power battery 141 is substantially parallel to the up-down direction of the electric scooter 100, thereby lifting the center of gravity of the electric scooter 100 to provide better maneuverability to the electric scooter 100.

As shown in fig. 2 and 3, as an alternative implementation, the electric scooter 100 further includes a seat cushion 15, and the seat cushion 15 is detachably disposed on the fixed bracket 113. A storage box 16 is provided on the underside of the seat cushion 15. By providing the power battery 141 on the support bracket 112, more space can be provided for the arrangement of the storage box 16 in the electric scooter 100.

Compared to the related art, since the power battery 141 is disposed substantially at the lower side of the seat cushion 15, in order to protect the power battery 141, the seat cushion 15 can completely cover the power battery 141, i.e., the width of the seat cushion 15 in the left-right direction is set to be greater than the width of the power battery 141 in the left-right direction. It is understood that when the width of the seat cushion 15 is excessively large, the riding experience of the driver is affected and it is inconvenient for the driver to support the electric scooter 100 with both legs.

As shown in fig. 2, in the present embodiment, since the power battery 141 is provided on the support frame 112, it is possible to improve the comfort of the driver driving the electric scooter 100 by reducing the width of the seat cushion 15. The seat cushion 15 includes a front end near the power battery 141, and a ratio between a width L1 of the front end of the seat cushion 15 and a width L2 of the electric scooter 100 is set to 0.6 or more and 0.9 or less. Alternatively, the ratio between the width L1 of the front end of the seat cushion 15 and the width L2 of the electric scooter 100 is set to 0.65 or more and 0.85 or less. Specifically, the ratio between the width L1 of the front end of the seat cushion 15 and the width L2 of the electric scooter 100 is set to 0.7 or more and 0.8 or less. More specifically, the ratio between the width L1 of the front end of the seat cushion 15 and the width L2 of the electric scooter 100 is set equal to 0.75. With the above arrangement, it is avoided that the width L1 of the front end of the seat cushion 15 is too large to facilitate the support of the electric scooter 100 by both legs of the driver. Further, it is avoided that the width L1 of the front end of the seat cushion 15 is excessively small to affect the comfort of the driver sitting on the seat cushion 15.

It will be appreciated that the electric scooter 100 further comprises a steering system 17, the steering system 17 is connected to the mounting bracket 111, and due to the limited length of the pedal 114 in the fore-and-aft direction, interference of the power battery 141 with the arrangement of the steering system 17 is avoided.

As shown in fig. 3 and 4, the three-electric system 14 further includes a driving motor 142 and a motor controller 143 as an implementation. When the power battery 141 is disposed on the support bracket 112, the power battery 141, the motor controller 143, and the driving motor 142 are sequentially arranged in the front-rear direction of the electric scooter 100. When the power battery 141 is disposed on the support bracket 112, the power battery 141 can extend beyond the end surface of the step 114 and toward the upper side of the step 114. The height of the power battery 141 beyond the pedal 114 in the up-down direction of the electric scooter 100 is set to H1. The height H1 of the power battery 141 above the step plate 114 is set to 160mm or more and 240mm or less. Specifically, the height H1 of the power battery 141 above the step plate 114 is set to 180mm or more and 230mm or less. More specifically, the height H1 of the power battery 141 above the step plate 114 is set equal to 200mm. In the above arrangement, it is avoided that the driving experience of the driver is affected by the fact that the height H1 of the power battery 141 exceeding the pedal 114 is too large. In addition, avoiding that the height H of the power battery 141 exceeding the stepping plane is too small results in that the volume of the power battery 141 is too small to meet the endurance requirement of the electric scooter 100.

As shown in fig. 3, as one implementation, the power battery 141 includes a first end surface close to the front wheel 131 and a second end surface far from the front wheel 131, wherein the first end surface of the power battery 141 and the second end surface of the power battery 141 are perpendicular to the front-rear direction of the electric scooter 100. A distance between the first end surface of the power battery 141 and the rotation axis of the front wheel 131 distributed in the front-rear direction of the electric scooter 100 is set to D1, and a distance between the second end surface of the power battery 141 and the rotation axis of the front wheel 131 distributed in the front-rear direction of the electric scooter 100 is set to D2. The distance D1 between the first end surface of the power battery 141 and the rotational axis of the front wheel 131 is set to 300mm or more and 460mm or less. The distance D2 between the second end face of the power cell 141 and the rotation axis of the front wheel 131 is set to 660mm or more and 1000mm or less. Specifically, the distance D1 between the first end surface of the power battery 141 and the rotation axis of the front wheel 131 is set to 340mm or more and 430mm or less. The distance D2 between the second end face of the power cell 141 and the rotation axis of the front wheel 131 is set to 750mm or more and 920mm or less. More specifically, the distance D1 between the first end surface of the power battery 141 and the rotational axis of the front wheel 131 is set equal to 380mm. The distance D2 between the second end face of the power cell 141 and the rotation axis of the front wheel 131 is set equal to 840mm. With the above arrangement, interference with the steering system 17, and/or the suspension system 12, caused by an excessively small distance between the power battery 141 and the front wheels 131, is avoided. In addition, the power battery 141 occupying the space of the storage box 16 caused by the overlarge distance between the power battery 141 and the front wheel 131 is avoided.

In summary, compared with the related art, the power battery 141 is disposed below the pedal 114, or the power battery 141 is disposed at the lower side of the seat cushion 15. In the present embodiment, the power battery 141 is at least partially disposed on the support frame 112. More space is provided for the power battery 141 without raising the pedal 114. As shown in fig. 2, on a projection plane 102 perpendicular to the front-rear direction of the electric scooter 100, the power battery 141 and the pedal 114 have a substantially "convex" shape in the contour projected on the projection plane 102 along the front-rear direction of the electric scooter 100. Through the above arrangement, while providing a layout space for other electrical components of the electric scooter 100, the gravity center height of the electric scooter 100 is raised, so that the maneuverability and flexibility of the electric scooter 100 are higher.

It is understood that the stacking manner of the power cells 141 is not limited to the above-described embodiment. The stacking manner of the power cells 141 can be adjusted according to actual conditions based on the external shape of the power cells 141. Specifically, embodiments that are disposed on the supporting frame 112 and can extend toward the upper side of the pedal 114 to increase the space for the storage box 16 are within the scope of the present application.

As shown in fig. 3, as one implementation manner, in addition to the pedals 114, a mounting portion 115 is further disposed on the supporting frame 112, and the mounting portion 115 is disposed between the left and right pedals 114 and is used for covering the power battery 141, so as to prevent the power battery 141 from being exposed outside the electric scooter 100, and to protect the power battery 141.

Specifically, an end surface of the mounting portion 115 facing the upper side of the electric scooter 100 is provided with an opening (not shown). Wherein the opening is arranged to be opened or closed, thereby facilitating the replacement of the power battery 141. It can be understood that, through the opening of the mounting portion 115, in case that the remaining capacity of the power battery 141 is insufficient or the power battery 141 is damaged, the battery replacement operation of the electric scooter 100 can be realized.

Further, the mounting portion 115 and the pedal 114 form a receiving space 116 for disposing the power battery 141 around the supporting bracket 112, wherein the width of the receiving space 116 distributed in the left-right direction of the electric scooter 100 is greater than the width of the power battery 141 distributed in the left-right direction of the electric scooter 100. So that other parts of the electric scooter 100, such as the wiring harness 144, the junction box 19, etc., can be disposed in the accommodating space 116 in addition to the power battery 141. Thereby improving the space utilization of the electric scooter 100 and making the space layout of the electric scooter 100 more compact.

As shown in fig. 3, more specifically, the electric scooter 100 further includes a heat dissipation system 18, the heat dissipation system 18 includes cooling ducts (not shown) extending in the front-rear direction, the cooling ducts can be inserted into the accommodation space 116, that is, the cooling ducts are disposed at the lower side of the pedal 114, and the cooling ducts are distributed at the left and right sides of the power battery 141. By providing the accommodation space 116 for accommodating the cooling duct, interference of the power battery 141 with the arrangement of the cooling duct is avoided. In addition, since the power battery 141, the motor controller 143 and the driving motor 142 are arranged substantially in the front-rear direction, in order to realize the cooling effect of the motor controller 143 and the driving motor 142, the extending direction of the cooling duct is substantially parallel to the front-rear direction of the electric scooter 100, thereby shortening the length of the cooling duct and reducing the production cost of the electric scooter 100.

As shown in fig. 2 and 3, as an implementation manner, the power battery 141 includes a cover surface 1411 on which a handle can be disposed, and the handle grasping the power battery 141 can carry the power battery 141. When the power battery 141 is disposed on the supporting bracket 112, a cover surface 1411 of the power battery 141 is substantially perpendicular to the up-down direction of the electric scooter 100. And the height of the cover surface 1411 of the power battery 141 from the ground is set to H2 in the up and down direction of the electric scooter 100. The height H2 of the covering surface 1411 of the power battery 141 from the ground is set to be greater than or equal to 400mm and less than or equal to 600mm. Specifically, the height H2 of the cover surface 1411 of the power battery 141 from the ground is set to be 450mm or more and 550mm or less. More specifically, the height H2 of the covering surface 1411 of the power battery 141 from the ground is set equal to 500mm. Therefore, the difficulty in assembling and disassembling the power battery 141 caused by the fact that the ground clearance H2 of the covering surface 1411 of the power battery 141 is too large is avoided, and the convenience in replacing the power battery 141 is improved.

As shown in fig. 3 and 4, as one implementation, the motor controller 143 is disposed at a rear side of the power battery 141, and the motor controller 143 is disposed at a front side of the driving motor 142. The electric scooter 100 further includes a storage box 16 disposed at a lower side of the seat cushion 15, and the motor controller 143 is disposed at a front lower side of the storage box 16 to prevent the motor controller 143 from interfering with a possibility that the storage box 16 is distributed in a front-rear direction and an up-down direction. Thereby making the arrangement of the three electrical systems 14 in the electric scooter 100 more compact.

Further, the motor controller 143 includes a bottom surface 1431, wherein the bottom surface 1431 of the motor controller 143 is set as a side end surface where the area of the motor controller 143 is the largest. The bottom surface 1431 of the motor controller 143 is disposed toward the power battery 141, i.e., the bottom surface 1431 of the motor controller 143 is substantially perpendicular to the front-rear direction of the electric scooter 100, so that the arrangement space occupied by the motor controller 143 in the front-rear direction is reduced to make the arrangement between the motor controller 143 and the power battery 141 more compact.

As shown in fig. 3 and 4, as one implementation, the driving motor 142 is disposed at the rear side of the motor controller 143, and the driving motor 142 is disposed at the front side of the rear wheel 132. Specifically, the electric scooter 100 further includes a transmission (not shown) through which the driving motor 142 is connected with the rear wheel 132. Thereby increasing the distance between the driving motor 142 and the rear wheel 132 in the front-rear direction of the electric scooter 100. In the case where the driving motor 142 is connected to the rear wheel 132 through a transmission, the driving motor 142 is a center motor. The torque of the driving motor 142 can be increased and the output power of the driving motor 142 can be reduced by the middle motor. Thereby improving the cruising ability of the electric scooter 100.

As shown in fig. 5, further, the driving motor 142, the motor controller 143 and the power battery 141 are distributed along the front-rear direction of the electric scooter 100 to have a total length D3 of the three-electric system 14. The total length D3 of the three electric systems 14 is set to 530mm or more and 800mm or less. Specifically, the total length D3 of the three-electric system 14 is set to 600mm or more and 730mm or less. More specifically, the total length D3 of the three-electric system 14 is set equal to 670mm. Through the arrangement, the total length of the three-electric system 14 in the whole vehicle arrangement is shortened, and more storage spaces are reserved for the electric scooter 100.

As one implementation, in order to reduce the layout space occupied by the three-electric system 14 in the forward and rearward directions of the electric scooter 100, a layout space is provided for other components of the electric scooter 100, such as the storage compartment 16. The distance between the rotation axis of the front wheel 131 and the rotation axis of the rear wheel 132 in the forward and backward direction of the electric scooter 100 is set to the wheel base D4 of the electric scooter 100. The ratio between the overall length D3 of the three-wire system 14 and the wheelbase D4 of the electric scooter 100 is equal to or greater than 0.43 and equal to or less than 0.53. Specifically, the ratio between the total length D3 of the three-electric system 14 and the wheelbase D4 of the electric scooter 100 is equal to or greater than 0.46 and equal to or less than 0.5. More specifically, the ratio between the overall length D3 of the three-electric system 14 and the wheelbase D4 of the electric scooter 100 is equal to 0.48. With the above arrangement, it is avoided that the span of the three-electric system 14 distributed in the front-rear direction of the electric scooter 100 is excessively large to occupy more space in the entire vehicle arrangement. So that the electric scooter 100 can have more space for arranging the storage compartment 16. Further, the three-electric system 14 is prevented from occupying an excessive space in the storage box 16 due to the overlapping in the vertical direction.

As shown in fig. 5, specifically, suspension system 12 includes an upper link plate 121 and a lower link plate 122, upper link plate 121 being disposed between steering system 17 and frame 11, and lower link plate 122 being disposed between frame 11 and suspension system 12. The upper link plate 121 and the lower link plate 122 cooperate to enable steering control of the steering system 17 to be transmitted to the front wheels 131 along the suspension system 12, thereby controlling the direction of movement of the front wheels 131. Further, a center circular hole is formed in the upper connecting plate 121, and when the steering system 17 rotates, the upper connecting plate 121 can rotate around the axis of the center circular hole of the upper connecting plate 121, that is, the center of the center circular hole of the upper connecting plate 121 is set as the rotation center of the upper connecting plate 121. A line connecting the rotation center of the upper link plate 121 and the ground point of the rear wheel 132 is set to a first preset straight line 103. The lower connecting plate 122 is provided with a central circular hole, and when the steering system 17 rotates, the lower connecting plate 122 can rotate around the axis of the central circular hole of the lower connecting plate 122, that is, the center of the central circular hole of the lower connecting plate 122 is set as the rotation center of the lower connecting plate 122. A line connecting the rotation center of the lower link plate 122 and the ground point of the rear wheel 132 is set to the second preset straight line 104. In the above arrangement, the center of gravity of the electric scooter 100 is substantially set within the included angle formed by the first preset straight line 103 and the second preset straight line 104.

In summary, the power battery 14 is disposed on the supporting frame 112 to move the center of gravity of the electric scooter 100 forward. And a power battery 141 capable of extending to an upper side of the step 114 is provided to raise the center of gravity of the electric scooter 100, so that the electric scooter 100 has better maneuverability and flexibility.

It is understood that the center of gravity of the electric scooter 100 can be shifted based on the arrangement position change of the three-electric system 14. By adjusting the position of the center of gravity of the electric scooter 100, the electric scooter 100 can travel more stably, and the maneuverability of the electric scooter 100 is improved.

As one implementation, the center of gravity 105 of the electric scooter 100 is also shown in fig. 4, and the length between the rotation axis of the front wheel 131 and the center of gravity 105 of the electric scooter 100 is set to a front shaft length D5 and the length between the rotation axis of the rear wheel 132 and the center of gravity 105 of the electric scooter 100 is set to a rear shaft length D6 in the front-rear direction of the electric scooter 100. The ratio between the front shaft length D5 and the rear shaft length D6 is 0.7 or more and 1 or less. Specifically, the ratio between the front shaft length D5 and the rear shaft length D6 is 0.8 or more and 0.95 or less. More specifically, the ratio between the front shaft length D5 and the rear shaft length D6 is equal to 0.9. Through the above arrangement, the phenomenon that the electric scooter 100 accelerates to raise the head due to the fact that the gravity center 105 of the electric scooter 100 leans backwards is avoided because the ratio between the front shaft length D5 and the rear shaft length D6 is too large. Furthermore, situations are avoided where the ratio between the front shaft length D5 and the rear shaft length D6 is too small, resulting in a forward center of gravity 105 of the electric scooter 100, which may cause steering difficulties. In conclusion, the driving experience of the driver is improved by adjusting the center of gravity 105 of the electric scooter 100 to enable the electric scooter 100 to have better maneuverability.

As shown in fig. 3 and 4, as one implementation, in order to increase the volume of the storage compartment 16, the electric scooter 100 has a larger storage space. The driving motor 142 and the motor controller 143 are both disposed at the lower side of the storage box 16, and both the driving motor 142 and the motor controller 143 do not exceed the covering surface 1411 of the power battery 141 along the up-down direction of the electric scooter 100. In the present embodiment, the heights of the power battery 141, the motor controller 143, and the driving motor 142 from the ground are substantially the same. Thereby avoiding the drive motor 142 and the motor controller 143 from occupying an excessive arrangement space in the up-down direction. By providing the drive motor 142 and the motor controller 143 at substantially the same height from the ground, the volume V of the storage compartment 16 is increased.

Specifically, the storage compartment 16 may be used to store a battery backup (not shown) to increase the range of the electric scooter 100. The volume V of the storage box 16 is set to be not less than 26dm ³ And is not more than 40dm ³ . Further, the volume V of the storage box 16 is set to 30dm or more ³ And is not more than 37dm ³ . More specifically, the volume V of the storage box 16 is set equal to 33dm ³ . In the above arrangement, it is avoided that the capacity V of the storage box 16 is too small to accommodate the backup battery. In addition, because the electric scooter 100 has no possibility of expanding the height in the up-down direction and the width in the left-right direction, the driving experience of the driver is prevented from being influenced by the overlarge volume V of the storage box 16.

It will be appreciated that the range and speed capabilities of the electric scooter 100 are enhanced by the compact arrangement of the three-electric system 14 such that the storage compartment 16 has a larger storage space to accommodate the battery backup. Specifically, when the backup battery is provided in the storage box 16, the backup battery can be electrically connected to the motor controller 143 and the driving motor 142.
