The plane perpendicular to the front-rear direction is the third plane. The two first bending portions 1131a are projected on the third plane in the front-rear direction in an "eight" shape.

In this arrangement, the projection angle α is within a suitable range, so that a suitable strength can be provided, and the length of the support frame assembly 113 can be limited as much as possible to achieve light weight. It can be appreciated that when the projection angle α is set to be greater than this range, the length of the support frame assembly 113 is too small to meet the installation requirement; when the ratio of the projection angle α is smaller than this range, the length of the support frame assembly 113 is too long, which is unfavorable for light weight, and easy to shake, and the installation strength is easily affected.

Specifically, the first mounting plate 1431 and the second mounting plate 1432 are fixed to the seat cushion 141 and the seat barrel 142 by bolts, and the first mounting portion 1431a and the second mounting portion are respectively provided with a plurality of mounting holes for connection, and the inner contour of the mounting holes corresponds to the inner contour and the number of the mounting holes provided on the seat cushion 141 and the seat barrel 142. The first connecting portion 1431b and the second connecting portion are fixed by a pin 1433, and the seat cushion 141 and the seat barrel 142 are rotatably connected. The pin 1433 includes a pin head 1433a and the projection 1411 is disposed in abutment with the assembled pin head 1433 a. In assembly, the first mounting plate 1431 and the second mounting plate 1432 are first connected by a pin. And the first mounting plate 1431 is connected with the seat barrel 142 through bolts, and finally the second mounting plate 1432 is connected with the seat cushion 141 through bolts, so that after the assembly is completed, the protruding part 1411 is just abutted with the pin shaft head 1433a, and the axial movement of the pin shaft 1433 is blocked. In this arrangement, the protrusions 1411 prevent the pin 1433 from being disengaged without the need for a nut or cotter pin.

As shown in fig. 9, the seat cushion apparatus 14 further includes a seat cushion lock assembly 144, and the seat cushion lock assembly 144 is configured to lock the seat cushion 141 such that the seat cushion 141 and the seat bucket 142 form a relatively closed space. Specifically, the cushion lock assembly 144 includes a switch 1441, a lock member 1442, and a cushion cable 1443. The seat cushion 141 includes a first state locked to the frame 11 and a second state unlocked from the frame 11. The lock member 1442 is fixed to the frame 11, and the seat cushion 141 is connected to the frame 11 via the lock member 1442, so that the seat cushion 141 is maintained in the first state. One end of the cushion cable 1443 is connected to the lock member 1442, and the other end of the cushion cable 1443 is connected to the switch 1441, and the lock member 1442 can disconnect the cushion 141 from the lock member 1442 in response to the trigger of the switch 1441, so that the cushion 141 is switched from the first state to the second state. A switch 1441 is provided at the front of the electric two-wheeled vehicle 100 to facilitate the operation of the driver.

As an alternative embodiment, cushion cable 1443 includes a first protective layer 1443a, a second protective layer 1443b, a cable wire 1443c, and a cable head (not shown). The first protective layer 1443a is provided on the outermost layer, and the first protective layer 1443a is a waterproof material layer. The second protective layer 1443b is disposed outside the cable 1443c and inside the first protective layer 1443 a. The second protective layer 1443b is provided as a straight type low spiral wound wire. The pull cord 1443c is disposed at the innermost layer and is displaceable relative to the second protective layer 1443 b. The pull cord 1443c is made of metal and is not easy to deform. The cable head sets up at the end of cable rope 1443, and the cable head is used for cooperating locking piece 1442 to lock and unblank. The seat cushion further includes a connecting member (not shown), one end of the locking member 1442 is connected to a cable head, and the cable head is capable of disconnecting the connecting member from the locking member 1442 in response to a trigger of the switch 1441, so that the seat cushion 141 is switched from the first state to the second state.

Specifically, the cable 1443c extends, and the cable head is locked with the locking member 1442 at a fixed distance or longer from the end of the second protection layer 1443 b. The pull rope 1443c is retracted into the second protection layer 1443b, and the end of the pull rope head and the end of the second protection layer 1443b are smaller than or equal to the unlocking distance, so that the locking piece 1442 is unlocked. Wherein, fixed distance is greater than the unblock distance. When the driver is locked by the switch 1441, the guy rope 1443c is extended, and the guy rope head extends out of the fixed distance of the second protection layer 1443 b; when the driver unlocks with the switch 1441, the cable 1443c is pulled, the length of the cable 1443c extending out of the second protection layer 1443b is reduced, and when the distance that the cable 1443c extends out of the second protection layer 1443b is smaller than the unlocking distance, the cushion lock assembly 144 is released. In this unlocking mode, the cushion cable 1443 is bent by an external force, for example, by bending by hand, so that the second protection layer 1443b will not become longer, and when the cushion 141 is in the first state, even if the cushion cable 1443 is bent, the length of the second protection layer 1443b is still less than or equal to the initial length of the second protection layer 1443b, that is, the length of the cable 1443c extending out of the second protection layer 1443b will not decrease. At this time, the portion of the stay 1443c extending out of the second protection layer 1443b is not smaller than the unlocking distance without using the switch 1441. Therefore, with this arrangement, the cushion cable 1443 is not unlocked even if the exposed portion is bent by an external force, improving the safety of the cushion lock assembly 144, and reducing the requirements for the arrangement position of the cushion cable 1443.

As shown in fig. 12 and 13, the illumination mechanism 16 includes a front illumination assembly 161 and a rear illumination assembly 162. The front lighting assembly 161 is provided at the front of the electric two-wheeled vehicle 100, and the front lighting assembly 161 integrates functions of position lamps and left and right turn lamps provided at left and right sides. The front lighting assembly 161 of the conventional electric two-wheeled vehicle 100 has left and right turn lamps separately provided on both sides. Thus, the integration level of the front car lamp of the vehicle is lower, and the wiring is more complicated. Meanwhile, the left steering lamp and the right steering lamp are independently arranged on two sides to easily generate the problems of collision damage and the like, so that the service lives of the left steering lamp and the right steering lamp are low, frequent replacement is needed, and the use cost is increased. In this arrangement, the front lighting assembly 161 is more compact, space efficient, and less prone to damage.

As an alternative embodiment, front lighting assembly 161 includes a first lighting area 1611, a second lighting area 1612, a third lighting area 1613, and a control module (not shown). On a first plane perpendicular to the left-right direction, the electric two-wheeled vehicle 100 is substantially bilaterally symmetrical about the first plane. The front lighting assembly 161 extends in a left-right direction of the electric two-wheeled vehicle, a first lighting region 1611 is provided in a middle portion of the front lighting assembly 161, a second lighting region 1612 and a third lighting region 1613 are provided at both ends of the front lighting assembly 161, respectively, and the second lighting region 1612 and the third lighting region 1613 are substantially bilaterally symmetrical about a first plane.

The first illumination region 1611 is provided with position lights, and the second illumination region 1612 and the third illumination region 1623 are each provided with position lights and turn lights. The electric two-wheeled vehicle 100 includes a normal running state and a steering state. When the electric two-wheeled vehicle 100 is in a normal running state, the lamp of the front lighting assembly 161 is turned off; when the electric two-wheeled vehicle 100 is in the normal running state, the position lamps of the first illumination region 1611, the second illumination region 1612, and the third illumination region 1623 are turned on; when the electric two-wheeled vehicle 100 is in the steering state, the position light of the first illumination region 1611 is turned on, and the second illumination region 1612 or the third illumination region 1623 is turned on. On the second illumination area 1612 or the third illumination area 1613, the position lamp and the turn lamp share an illumination area, and the light emission forms of the position lamp and the turn lamp are that light such as position source light is reflected by a reflecting bowl firstly and then is emitted by a thick-wall piece light distribution pattern; the light of the position lamp and the steering lamp is reflected and transmitted out through different parts of the same reflecting bowl and the thick-wall part, so that two optical functions of the same area are realized.

As an alternative embodiment, front lighting assembly 161 further includes an operating member 1614. The control module includes a control unit and an output unit, the operating member 1614 is capable of transmitting a control instruction to the control unit in response to an external force, and the control unit is capable of determining an indication result for the first, second, and third illumination areas 1611, 1612, and 1613 according to the control instruction from the key. Wherein the indication result can indicate that the output unit controls different lights of the first, second and third illumination areas 1611, 1612 and 1613. Specifically, the control unit can be connected to the manipulation member by a cable, and when the driver manipulates the manipulation member 1614, the control unit can receive an instruction transmitted from the manipulation member and determine the result of the instruction of the driver for the first, second, and third illumination areas 1611, 1612, and 1613 according to the instruction. The operating element 1614 may be configured as a key, and the key generates a control command in response to a force applied by a driver in a manner of touching, pressing, or the like the key and transmits the command to the control unit, and determines a result of indication of the driver for the first illumination region 1611, the second illumination region 1612, and the third illumination region 1613, for example, an indication of "the first illumination region 1611 is switched to the position light", "the second illumination region 1612 is switched to the turn light", "the second illumination region 1612 is switched to the position light", "the third illumination region 1613 is switched to the turn light", or "the third illumination region 1613 is switched to the position light", or the like, according to the command.

As an alternative embodiment, the projected area of the first illumination region 1611 on the third plane in the front-rear direction is S1, the projected area of the front illumination assembly 161 on the third plane in the front-rear direction is S2, and the ratio of S1 to S2 is set within a certain range, more specifically, the ratio of S1 to S2 may be 0.20 or more and 0.50 or less; as an alternative embodiment, the ratio of S1 to S2 may be 0.25 or more and 0.45 or less; as an alternative embodiment, the ratio of S1 to S2 may be 0.30 or more and 0.40 or less. In this arrangement, the ratio of S1 to S2 is in a suitable range, so that the vehicle signal can be displayed to meet the lighting requirement, and the size of the front lighting assembly 161 can be limited as much as possible to achieve light weight. It can be appreciated that when the ratio of S1 to S2 is set to be greater than this range, the area of the second illumination area 1612 or the third illumination area 1613 is too small, and the left and right turn lights are too small to clearly display the vehicle signal; when the ratio of S1 to S2 is set to be smaller than this range, the first illumination area 1611 is too small and the illumination intensity of the position lamp is insufficient. It is understood that S1 and S2 may be 0.22, 0.28, 0.34, 0.42, etc.

As shown in fig. 12 and 13, the back lighting assembly 162 is disposed rearward of the seat pan 142 and below the seat cushion 141. The seating bucket 142 includes a mounting portion 1421, and the backlight assembly 162 is disposed at the mounting portion 1421 by bolts. The rear lighting assembly 162 integrates the functions of a position light, a brake light, and a rear turn light. The rear lighting assembly 162 of the conventional electric two-wheeled vehicle 100 often has a low integration level and a more complicated wiring because the position light, the brake light and the rear turn light are independently installed. The rear lighting assembly 162 includes a first lighting area 1621, a second lighting area 1622, and a third lighting area 1623, the rear lighting assembly 162 extends in the left-right direction, the middle of the rear lighting assembly 162 is provided as the first lighting area 1621, and both ends of the rear lighting assembly 162 are provided as the second lighting area 1622 and the third lighting area 1623, respectively. The first illumination area 1621 includes a position light and a stop light, the brightness of the position light being less than the brightness of the stop light. The second and third illumination areas 1622 and 1623 are each provided with a turn signal. The electric two-wheeled vehicle 100 includes a normal running state, a braking state, and a steering state. When the electric two-wheeled vehicle 100 is in a normal running state, the position light of the first illumination area 1621 is turned on, and the turn lights of the second illumination area 1622 and the third illumination area 1623 are turned off; when the electric two-wheeled vehicle 100 is in a braked state, the brake lamps of the first illumination region 1621 are turned on, and the turn lamps of the second illumination region 1622 and the third illumination region 1623 are turned off; when the electric two-wheeled vehicle 100 is in the steering state, the position light of the first illumination area 1621 is turned on, and the steering light of the second illumination area 1622 or the third illumination area 1623 is turned on. In this arrangement, the rear lighting assembly 162 integrates multiple lamps, and the arrangement is more compact and space efficient. The position lamp and the brake lamp part reflect light source light through the reflecting bowl and then penetrate through the light distribution inner cover, so that the brightness required by the brake lamp is realized; the steering lamp part refracts light source light through a very small thick-wall part, so that the requirement of the spacing distance of the steering lamp is met.

As an alternative embodiment, the overlapping area of the projection of the back illumination assembly 162 on the second plane and the projection of the seat cushion 141 on the second plane in the up-down direction is S3, the projection area of the back illumination assembly 162 on the second plane is S4, and the ratio of S3 to S4 is set within a certain range, more specifically, the ratio of S3 to S4 may be 0.50 or more and 0.92 or less; as an alternative embodiment, the ratio of S3 to S4 may be 0.60 or more and 0.85 or less; as an alternative embodiment, the ratio of S3 to S4 may be 0.70 or more and 0.80 or less. In this arrangement, the ratio of S3 to S4 is in a suitable range, and the rear lighting assembly 162 is compact and can display vehicle signals. It can be appreciated that when the ratio of S3 to S4 is set to be greater than this range, the rear lighting assembly 162 is too much hidden under the seat cushion 141 to meet the lighting requirement; when the ratio of S3 to S4 is set to be smaller than this range, the overlapping degree of the illumination device 162 and the seat cushion 141 is too low, and the space utilization ratio is not high, as viewed in the up-down direction of the electric two-wheeled vehicle 100. It is understood that the ratio of S3 to S4 may be 0.55, 0.62, 0.75, etc.

As shown in fig. 10 and 14, the rear wheel 132 further includes a tire 1322, a rim 1323, spokes 1324, and a valve 1325. The tire 1322 is used to store gas. A valve 1325 is provided on the tire 1322 for inflating and deflating the tire 1322. Specifically, the valve 1325 is provided on the rim 1323 on the side that contacts the spoke 1324, and the valve 1325 is inclined to the side that is away from the running mechanism 13. The valve 1325 is substantially overlapped with the rear wheel 132 when viewed from the up-down direction of the electric two-wheeled vehicle 100. The rim 1323 is provided with a mounting surface 1323a for connection with the valve 1325, and the valve 1325 is provided substantially perpendicular to the mounting surface 1323 a. The angle γ between the mounting face 1323a and the second plane is set to 20 ° or more and 40 ° or less. In this arrangement, since the included angle between the mounting surface 1323a and the second plane is set within a specific angle range, the valve 1325 is set to be linear, and no bending is required, so that the cost is saved while the convenience of inflation is satisfied.

As an alternative embodiment, the electric two-wheeled vehicle 100 further includes a brake mechanism (not shown), and the brake mechanism is disposed on one side of the rear wheel 132, so as to avoid the valve 1325 from adversely affecting the disposition and installation of the brake mechanism, and simultaneously to facilitate inflation of the running gear 13, so that the valve 1325 and the brake mechanism are disposed on both sides of the rear wheel 132, respectively. As another implementation, the included angle γ between the mounting face 1323a and the second plane is set to 25 ° or more and 35 ° or less. As another implementation, the included angle γ between the mounting face 1323a and the second plane is set to 28 ° or more and 32 ° or less. In this arrangement, the included angle γ between the mounting surface 1323a and the second plane is set to be in a suitable range, so that the inflation requirement can be met, interference with other mechanisms can be avoided as much as possible, and an attractive effect is achieved. It will be appreciated that when the angle γ between the mounting face 1323a and the second plane is set to be greater than this range, the valve 1325 is too far from the rim 1323, and is exposed to damage and aesthetic effects. When the angle γ between the mounting surface 1323a and the second plane is set to be smaller than this range, the valve 1325 is too close to the rim 1323 and the spoke 1324, and is liable to interfere with each other when inflated, which is inconvenient. It is understood that the included angle γ between the mounting face 1323a and the second plane may be set to 26 °, 32 °, 34 °, 37 °, or the like.
