Description

Wire connecting mechanism and wiring structure for two-wheeled electric vehicle

Technical Field

The invention relates to an electric vehicle, in particular to a foldable two-wheel electric vehicle.

Background

Along with the increasing severity of the modern urban traffic conditions, the electric vehicle is accepted by the masses more and more with the advantages of convenience, green environmental protection and the like. The traditional electric vehicle is large in size, heavy in weight and inconvenient to carry, and is unfavorable for conversion in public transportation and road surface running. At this time, portable folding electric vehicles are emerging as alternatives that can be carried to public transportation such as subways.

The existing folding electric vehicle is mainly used for directly folding the handle and the vehicle body together, however, the traditional folding mode has some defects. For example, the folded car body needs to carry one end of the wheel by hand to move the electric car, but because the electric car is provided with a battery pack and other devices, the electric car is too heavy and inconvenient to carry. Moreover, in the conventional folding manner, the length of the folded vehicle body is unchanged, and a large space is required for transportation means such as subways, etc., so that if the wheels are stained, the clothes of other people are easily stained. In addition, the transmission line used for transmitting signals/power on the folded vehicle body of the traditional electric vehicle is unreasonable in arrangement, so that the folded vehicle body occupies a larger space, and the transmission line is easy to damage when the electric vehicle is carried.

There is thus a need for a folding electric vehicle with an improved folding mechanism that overcomes the drawbacks of conventional folding electric vehicles.

fig. 1A, 1B, 1C, 1D and 1E show a two-wheeled electric vehicle 100 of the present invention as a whole. The two-wheeled electric vehicle 100 of the present invention has a front vehicle body 101 and a rear vehicle body 102, the front vehicle body 101 being connected to front wheels 161, and the rear vehicle body 102 being connected to rear wheels 162. The two-wheeled electric vehicle 100 of the present invention is foldable, and the relative positional relationship between the front vehicle body 101 and the rear vehicle body 102 is different in the folded state and the driving state of the two-wheeled electric vehicle 100 of the present invention. In the driving state, the front vehicle body 101 and the rear vehicle body 102 are fixedly connected with respect to each other such that the rear vehicle body 102 is substantially perpendicular to the front vehicle body 101, and the front wheels 161 and the rear wheels 162 are arranged front-to-back. When folding is required, the front body 101 and the rear body 102 can be separated (displaced) with respect to each other, so that after folding, the front body 101 and the rear body 102 can be abutted together side by side, and the front wheel 161 and the rear wheel 162 are folded together, i.e., the front wheel 161 and the rear wheel 162 are abutted on one side by side.

Since the two-wheeled electric vehicle 100 of the present invention needs to be switched between the driving state and the folded carrying state described above, how to separate and fix the front vehicle body 101 from the rear vehicle body 102 becomes an important subject of the present invention. The present invention provides a fixing structure to be described in detail below to achieve separation and fixation of the front vehicle body 101 from the rear vehicle body 102.

In addition, the two-wheeled electric vehicle 100 of the present invention can adopt a hidden line in addition to the folding method described above. That is, the route of the two-wheeled electric vehicle is hidden in the vehicle body from outside, both in the driving state of the two-wheeled electric vehicle and in the folded carrying state of the two-wheeled electric vehicle. Therefore, how to realize the above two state switching and simultaneously make the use of the hidden line possible is also an important subject of the present invention. Of course, the protection scope of the present invention is not limited to adopting the folding manner and the hidden line at the same time, and any technical solution adopting one of the folding manner and the hidden line falls within the protection scope of the present invention. The present invention realizes a hidden circuit by a wire connection mechanism and a wiring structure which will be described in detail below.

In the following, how to separate and fix the front body 101 from the rear body 102 will be specifically described with reference to the drawings.

As shown in fig. 1A, the front body 101 of the two-wheeled electric vehicle 100 includes a faucet bar 103, the upper end of the faucet bar 103 is a faucet portion 116, the lower end of the faucet bar 103 is provided with a front body cover 107, and the lower end of the front body cover 107 is connected to front wheels 161 via front wheel arms 164. The rear vehicle body 102 includes a platform-type rear frame 115 in its middle portion, and rear ends of the platform-type rear frame 115 are connected to rear wheels 162. The front end of the platform-type rear frame 115 is connected with a support rod 104, and the front end of the support rod 104 is connected with a rear car body sleeve 108. The rear body sleeve 108 has an interior cavity 306 (see fig. 3A-1, 3C-1) shaped to match the exterior shape of the front body sleeve 107 so that the front body sleeve 107 can nest within the interior cavity 306 of the rear body sleeve 108. The front end of the support rod 104 is provided with a locking mechanism 320 (see fig. 3B-1 and 3B-2) at a position adjacent to the rear body cover 108, and the locking mechanism 320 can lock the rear body cover 108 and the front body cover 107 together to prevent relative up-and-down movement, lateral shaking, etc. between the front body cover 107 and the rear body cover 108, so that the front body 101 and the rear body 102 of the two-wheeled electric vehicle 100 can be connected into a stable integral structure to realize safe running.

The support rod 104 is externally provided with a pulling mechanism 130 connected with the locking mechanism 320, and the pulling mechanism 130 is used for changing the working state of the locking mechanism 320 to be in a locking position or a releasing position so as to realize locking or releasing between the front vehicle body 101 and the rear vehicle body 102. The locked position of the trigger mechanism 130 is shown in fig. 1A.

Further, steering handles 171 and 172 are provided at both ends of the faucet portion 116. The twist steering handle 171 can control the speed of the two-wheeled electric vehicle, and the twist steering handle 172 can control the braking of the two-wheeled electric vehicle, etc. The outer surfaces of the middle parts of the steering handles 171 and 172 are provided with display devices for displaying vehicle running state information such as vehicle speed, battery power and the like.

The rear vehicle body 102 is provided with a power source, a motor, a braking device, etc. in addition to the rear wheels 162 (see fig. 2A to 2D for schematic block diagrams of these devices). A power source (e.g., a battery) is provided inside the platform rear frame 115.

Fig. 1B is a structural view of the two-wheeled electric vehicle of the present invention when the front body and the rear body are separated. As described above, the two-wheeled electric vehicle 100 of the present invention can be folded for convenience of carrying. Fig. 1B shows a case where the front body 101 and the rear body 102 are separated during folding of the two-wheeled electric vehicle 100. At this time, the pulling mechanism 130 is oriented in the horizontal direction, the lock mechanism 320 is in the release position, the fixed connection between the rear body cover 108 and the front body cover 107 is released, the front body cover 107 is pulled out of the rear body cover 108, and the rear body cover 108 moves upward along the tap lever 103. The rear body cover 108 is still nested on the faucet shank 103 at this point. Thus, reference to the separation of the front body 101 and the rear body 102 in the present invention refers to the relative separation between the two, and more specifically to the fact that the two can be moved up and down relative to each other to effect folding therebetween, but not completely disengaged from each other.

In a state where the front vehicle body 101 and the rear vehicle body 102 are separated as shown in fig. 1B, the front vehicle body 101 and the rear vehicle body 102 can rotate relative to each other, and fig. 1C is a structure diagram of the front vehicle body rotated 180 ° in fig. 1B. Because the shape of the inner cavity 306 of the rear body cover 108 matches the shape of the outer wall of the front body cover 107, the rear body cover 108 cannot rotate relative to the front body cover 107 when nested thereon. The outside diameter of the tap stem 103 is smaller than the inside diameter of the inner cavity 306 of the rear body sleeve 108 so that when the rear body sleeve 108 is separated from the front body sleeve 107 and the rear body sleeve 108 is moved up to fit over the tap stem 103 as shown in fig. 1B, the front body sleeve 107 can be rotated relative to the rear body sleeve 108. The front wheel arm 164 shown in fig. 1C is turned to the other side with respect to the rear vehicle body 102, as compared to that shown in fig. 1B. It can also be seen from fig. 1C that steering handles 171, 172 can also be folded individually and retracted for reducing the folded width of the two-wheeled electric vehicle.

Fig. 1D and 1E show block diagrams of the trigger mechanism of the present invention in a locked position and a released position, respectively. Fig. 1D shows the two-wheeled electric vehicle 100 of fig. 1A in a driving state, in which the pulling mechanism 130 is directed downward, and the locking mechanism 320 is in a locking position, locking the rear body cover 108 and the front body cover 107. To fold the two-wheeled electric vehicle 100 to the state shown in fig. 1B, the pulling mechanism 130 is twisted to be oriented in the horizontal direction (as shown in fig. 1E), so that the locking mechanism 320 is in the release position, and the rear body cover 108 and the front body cover 107 are released by the locking mechanism 320, so that the front body cover 107 can be pulled out from the rear body cover 108, and the state shown in fig. 1B is achieved.

Next, in connection with the wiring structure of the two-wheeled electric vehicle 100 of the present invention shown in fig. 2A, 2B, 2C and 2D, how the two-wheeled electric vehicle 100 of the present invention realizes electrical connection with a hidden circuit will be specifically described.

Fig. 2A is a schematic view of a wiring structure module according to a first embodiment of the present invention. The faucet 116 is used to control the running of the electric vehicle 100 while the electric vehicle is driving. As described above, some control functions of the two-wheeled electric vehicle 100 can be achieved by twisting the steering handles 171, 172. According to the embodiment of the present invention, the steering handles 171 and 172 are provided with an acceleration control device, a brake control device, a horn button, a cruise button, etc., and the steering handles 171 and 172 are screwed to control the control mechanism 205 to transmit a vehicle control signal, and the control mechanism 205 includes a speed control device 207, a brake control device 208, a horn control device 206, a cruise control device 209, etc. Meanwhile, as described above, the outer surface of the faucet 116 is provided with a display device 204 for displaying vehicle running status information such as vehicle speed, battery power, etc. The transmission of the control signal of the front vehicle body and the reception of the vehicle running information are performed by a first control circuit 203 provided inside the front vehicle body 101, and the first control circuit 203 is connected to a speed control device 207, a brake control device 208, a horn control device 206 (e.g., a horn button), a cruise control device 209 (e.g., a cruise button), a display device 204, and the like, respectively, and receives and transmits their respective control signals and display signals.

As mentioned earlier, the rear vehicle body 102 is provided with a power supply 223, a motor 224, a brake device 225, and the like in addition to the rear wheels 162. The charge/discharge signal of the power supply 223, the cruise mode control signal of the motor 224, the deceleration signal of the brake device 225, and the like are processed and transmitted by the second control circuit 222 provided inside the platform-type rear frame 115 of the rear vehicle body 102. The first control circuit 203 and the second control circuit 222 are integrated circuit boards having digital-to-analog conversion, data calculation, and data transmission/reception functions. The second control circuit 222 processes and transmits the charge/discharge signal, the cruise mode control signal, the deceleration signal, and the like to the first control circuit 203, so that the first control circuit 203 processes the above signals and transmits them to the display device 204, and the display device 204 displays battery information, cruise mode information, speed information, and the like. The first control circuit 203 processes and transmits the control signal sent by the control mechanism 205 to the second control circuit 222, so that the second control circuit 222 processes and controls the actions of the corresponding components (e.g., the motor 224, the brake 225).

As an example, 4 front wires 211 are provided inside the front vehicle body 101, which are a positive power supply line 211.1, a negative power supply line 211.2, and 2 signal lines 211.3, 211.4, respectively, the positive and negative power supply lines 211.1 and 211.2 being used for transmission of an operating voltage, and the signal lines 211.3 and 211.4 being used for transmission of signals. One end of the 4 front wires 211 is connected to the first control circuit 203, and the other end is connected to the front vehicle body wire connection device 201 provided in the front vehicle body cover 107.

In the present embodiment, 4 rear conductors 231 are provided in the rear vehicle body 102 in cooperation with the front conductors 211, and are respectively a positive power supply line 231.1, a negative power supply line 231.2, and 2 signal lines 231.3, 231.4, and the rear conductors 231 function identically to the front conductors 211. One end of the signal wires 231.3, 231.4 of the two rear wires 231 is connected with the second control circuit 222, and the other end is connected with the rear car body wire connecting device 221 arranged in the rear car body sleeve 108; the signal wires of the two rear conductors 231 are connected with the positive power supply wire 231.1 and the negative power supply wire 231.2, one end of which is connected with the power supply 223, and the other end of which is connected with the rear vehicle body conductor connecting device 221.

The front body wire connection device 201 and the rear body wire connection device 221 may be connected together such that the front wire 211 in the front body 101 and the rear wire 231 of the rear body 102 communicate.

Fig. 2B and 2C are schematic block diagrams of the wiring structure according to the first embodiment of the present invention shown in fig. 2A, when the front body wire connecting device and the rear body wire connecting device are conducted and separated, respectively. As shown in fig. 2B, when the two-wheeled electric vehicle 100 needs to enter a driving state, the rear vehicle body cover 108 is nested on the front vehicle body cover 107 and locks the two mutually, and at least four contacts on the front vehicle body wire connecting device 201 and at least four front contact pins on the rear vehicle body wire connecting device 221 are pressed and contacted mutually, so that 4 front wires 211 are electrically connected with 4 rear wires 231, and communication between power and signals is realized.

It should be noted that the front body wire connecting device 201 and the rear body wire connecting device 221 are in press contact with each other, not in plug-in contact, so that the front body wire connecting device and the rear body wire connecting device can be easily separated when the two-wheeled electric vehicle 100 needs to be brought into the folded state. The specific structure of the front car body wire connecting device 201 and the rear car body wire connecting device 221 will be described in detail below.

As shown in fig. 2C, when the two-wheeled electric vehicle 100 needs to enter the folded state, the front body cover 107 and the rear body cover 108 are moved apart up and down with respect to each other, thereby achieving mutual separation, and the contacts on the front body wire connecting device 201 and the front contact pins on the rear body wire connecting device 221 are also separated accordingly, so that the 4 front wires 211 are disconnected from the 4 rear wires 231, and the power transmission and signal communication of the front body 101 and the rear body 102 are interrupted.

Fig. 2D is a schematic diagram of a wiring structure module according to a second embodiment of the present invention. In the wiring structure according to the first embodiment of the present invention as shown in fig. 2A, the operating voltage of the components and circuits in the front vehicle body 101 needs to be supplied from the power supply 223 in the rear vehicle body 102, and thus one positive power supply lines 211.1 and 231.1 and one negative power supply line 211.2 and 231.2 are required in the front and rear wires 211 and 231 for power transmission. In fact, if the independently powered battery 227 is provided within the front body 101, the operating voltages of the components and circuits within the front body 101 may be independently supplied by the battery 227 without being provided by the power supply 223 within the rear body 102, and thus without the need for positive and negative power supply lines for transmitting power from the front and rear conductors 211, 231.

Further, in the wiring structure according to the first embodiment of the present invention as shown in fig. 2A, the front wire 211 and the rear wire 231 employ two signal wires 211.3, 211.4, 231.3, and 231.4 as connection wires for signal transmission, but signal transmission can be realized using one wire in fact.

Thus, in the wiring structure according to the second embodiment of the present invention as shown in fig. 2D, a separate battery 227 is provided in the front vehicle body 101, the battery 227 is connected to the first control circuit 203, and the first control circuit 203 is connected to the control mechanism 205 (including the speed control device 207, the brake control device 208, the horn control device 206, the cruise control device 209) and the display device 204, and provides power and signal transmission thereto. The first control circuit 203 is connected to the front vehicle body wire connection device 201 through 1 front wire 211. In the rear vehicle body 102, the second control circuit 222 is connected to the rear vehicle body wire connection device 221 via 1 rear wire 231.1. Other wiring structures in the rear vehicle body 102 are the same as those in fig. 2A, and are not described here.

At this time, at least 1 contact is required to be provided on the front body wire connecting device 201, at least 1 contact pin is required to be provided on the rear body wire connecting device 221, and when the front body wire connecting device 201 and the rear body wire connecting device 221 are brought into close contact with each other, the 1 contact pin and the 1 contact point are brought into contact with each other, so that the 1 front wire 211 communicates with the 1 rear wire 231, thereby achieving signal communication of the front body 101 and the rear body 102.

In fact, a plurality of redundant contacts and contact pins are provided on the front body wire connection 201 and the rear body wire connection 221 for ensuring the reliability of the contact connection.

In addition, fig. 2A and 2D show only two embodiments of the present invention as illustrative examples. Whether several signal wires are used, whether power wires are provided in the front body or not, or any combination thereof, are within the scope of the present invention.

In the following, it will be specifically described how the locking and releasing of the front body 101 and the rear body 102, and the connection and disconnection of the front body wire connecting device 201 and the rear body wire connecting device 221 are achieved in connection with the structure of the rear body cover 108 of the present invention and the related components thereof shown in fig. 3A-1 to 3G.

FIGS. 3A-1 and 3A-2 are perspective views of the rear car body cover of the trigger mechanism of the present invention in the release position and the lock position, respectively. FIG. 3C-1 is a top plan view of the rear body cover of the present invention, and FIG. 3C-2 is a cross-sectional view taken along line C-C' of FIG. 3C-1. As shown in these several figures, a rear body cover 108 of the two-wheeled electric vehicle 100 is provided at the front end of the support bar 104 (the upper portion of the support bar 104 in the figure is defined as the front end). The front side of the front end of the support rod 104 is a planar front side engagement plane 308 (see fig. 3C-2 in detail), and the rear body cover 108 extends from both side edges of the front side engagement plane 308 to form a tubular inner cavity 306, and one side (rear side) of the inner cavity 306 is the front side engagement plane 308. The interior cavity 306 may be adapted to nestingly receive the front body sleeve 107. Since the shape of the front body cover 107 is matched with the shape of the inner cavity 306, the front body cover 107 is tightly matched with the inner cavity 306 after being inserted into the inner cavity 306, and the cross section of the inner cavity 306 is non-circular due to the front side engagement plane 308, even if the front body cover 107 and the rear body cover 108 are not locked, the front body cover 107 and the rear body cover 108 do not rotate and shake relatively (but the front body cover 107 can be pulled out from the rear body cover 108).

As shown in fig. 3C-2, the front engaging plane 308 is rectangular, and two openings are provided on the front engaging plane 308, a first engaging window 318 above, and a second engaging window 322 below. As will be described in detail below, the locking mechanism 320 is movable through the first and second snap windows 318, 322 to a locked position interacting with the front body sleeve 107 located within the rear body sleeve 108 and a released position separated from each other with the front body sleeve 107 located within the rear body sleeve 108.

The front end of the support rod 104 is also provided with a locking mechanism cavity 310 adjacent the rear body cover 108 for receiving the locking mechanism 320 previously mentioned. One side of the locking mechanism cavity is provided with a mounting window 312 (see fig. 3G in detail) for the assembly and disassembly of the locking mechanism 320, and a window cover 150 for closing the mounting window 312. The pulling mechanism 130 is detachably installed at the outer side of the window cover 150.

The locking mechanism 320 is used to lock and release both the front body sleeve 107 and the rear body sleeve 108 as previously described. The lock mechanism 320 also enables connection and disconnection of the front body wire connecting device 201 and the rear body wire connecting device 221. As can be seen from fig. 3A-1, the trigger mechanism 130 for controlling the locking and releasing of the locking mechanism 320 is now oriented in a horizontal direction (as in fig. 1E) to release the locking mechanism 320, while the trigger mechanism 130 is oriented in a vertical direction (as in fig. 1D) in fig. 3A-2 to effect locking of the locking mechanism 320.

Fig. 3B-1 is a cross-sectional view of fig. 3A-1 taken along line A-A, fig. 3B-2 is a cross-sectional view of fig. 3A-2 taken along line B-B, and fig. 3B-1 and 3B-2 are used primarily to illustrate the distinction between the locking and release positions of the locking mechanism 320. As shown in fig. 3B-1 and 3B-2, the locking mechanism 320 basically includes a locking press block 314, a locking slide 324 (see fig. 3D-1-3D-3 in detail) and a drive shaft 330 (see fig. 3E-1-3E-3 in detail). The locking tab 314 may be pushed through a first engagement window 318 on the front engagement plane 308 to press against a rear engagement plane 311 of the front body shell 107 located in the rear body shell 108 (as will be described in detail below with reference to fig. 3I-1 through 3I-4), while the locking tab 324 may be pushed through a second engagement window 322 on the front engagement plane 308 to engage in a recess 313 on the rear engagement plane 311 of the front body shell 107 located in the rear body shell 108 (see fig. 3I-1 in detail) to lock the front body shell 107 with the rear body shell 108 such that the front body shell 107 and the rear body shell 108 are fully secured against relative up-down movement therebetween. Meanwhile, the locking slider 324 is engaged in the groove 313 to also enable connection of the front body wire connecting device 201 and the rear body wire connecting device 221, thereby enabling electrical connection of the front body 101 and the rear body 102, which will be described later.

The driving shaft 330 is connected to the pulling mechanism 130 through the window cover 150 of the locking mechanism accommodating cavity 310, and the driving shaft 330 is rotated by the pulling mechanism 130 to drive the locking press block 314 and the locking slide block 324 to move to lock and release the front car body cover 107, and to connect and disconnect the front car body wire connecting device 201 and the rear car body wire connecting device 221.

A cam mechanism is provided on the drive shaft 330 for driving the movement of the locking press 314 and the locking slide 324. Fig. 3E-1 to 3E-3 are multi-angle perspective structure views of the driving shaft 330. As shown in fig. 3E-1-3E-3, the cam mechanism includes a drive surface 332 and fingers 331. The driving surface 332 cooperates with the locking block 314 to move the locking block 314 in response to rotation of the driving shaft 330, and the fingers 331 cooperate with the locking slide 324 to move the locking slide 324 in response to rotation of the driving shaft 330, as will be described in detail below.

The distal end 305 of the drive shaft 330 is inserted into a hole (not shown) in the inner wall of the locking mechanism cavity 310 and the proximal end 307 of the drive shaft 330 is passed through the through hole 152 in the window covering 150 (as shown in fig. 3G) and connected to the trigger mechanism 130 such that the drive shaft 330 rotates with the trigger mechanism 130 when the trigger mechanism 130 is rotated by pulling.

Locking detent 314 and locking detent 324 are described below in conjunction with FIGS. 3B-1,3B-2,3D-1,3D-2,3D-3 and 3G. Wherein, fig. 3D-1 is a perspective structural view of the locking slide of the present invention, fig. 3D-2 is a sectional view of an inner structure of the locking slide of the present invention, fig. 3D-3 is an exploded structural view of the locking slide of the present invention, and fig. 3G is an exploded structural view of the support bar of fig. 3B-1 of the present invention.

As shown (particularly in fig. 3G), the locking pressing block 314 is a cube-shaped swing block, the top end 315 of the locking pressing block 314 is rotatably sleeved on a fixed shaft 317, and both ends of the fixed shaft 317 are fixed on the inner wall of the locking mechanism cavity 310, so that the locking pressing block 314 can swing around the fixed shaft 317 by rotating a certain angle. The side of the locking pressing block 314 facing the rear car body cover 108 is a locking plane 316, and the back surface of the locking plane 316 contacts with a driving surface 332 (see fig. 3E-1 to 3E-3) of the driving shaft 330, and when the driving shaft 330 rotates in a first rotation direction (e.g., clockwise), a clockwise rotation pushing force is provided to the locking pressing block 314 to push the locking pressing block 314 to swing toward a rear side engagement plane 311 of the front car body cover 107 located in the rear car body cover 108 and pass through the first engagement window 318 to reach a locking position (as shown in fig. 3B-2), so that the rear side engagement plane 311 is pressed by the locking pressing block 314 to prevent relative up-down movement between the front car body cover 107 and the rear car body cover 108 and/or lateral shaking between the front car body cover 107 and the rear car body cover 108. And when the drive shaft 330 is rotated in a second rotational direction (e.g., counterclockwise), the locking tab 314 is released such that the locking tab 314 can be withdrawn from the first engagement window 318.

The fixed shaft 317 is further sleeved with a return spring 319 (see fig. 3G), and the return spring 319 is a torsion spring, one end of which is fixed on the inner wall of the locking mechanism cavity 310, and one end of which is fixed on the locking pressing block 314. The return spring 319 is configured to provide a torsion force that swings the locking weight 314 counterclockwise, thereby swinging the locking weight 314 away from the rear engagement plane 311 of the front body cover 107 to the release position (as shown in fig. 3B-1) after the pushing force of the drive shaft 330 is released. In addition, when the driving shaft 330 is in the release position, the torsion of the return spring 319 makes the locking pressing block 314 not swing at will, thereby avoiding interference with other components.

The lock slide 324 is a slidable contact block that is movable in the left-right direction in the drawing between a lock position and a release position. As shown in fig. 3D-1 to 3D-3, the lock slider 324 has a substantially cubic structure and is hollow. The upper side edge of the locking slider 324 is provided with a catch 325, and the catch 325 is formed by catch arms 347 and 348. The fingers 331 of the drive shaft 330 are inserted into the notches 325 such that, as the drive shaft 330 rotates, the fingers 331 always abut against the inside of the retaining arms 347 or 348 (i.e., the sides adjacent to the notches 325) to generate a driving force for the back and forth movement of the lock slide 324. When the drive shaft 330 is rotated in a first rotational direction (e.g., clockwise), the fingers 331 push the locking slide 324 through the second engagement windows 322 on the front engagement plane 308 to engage in the grooves 313 on the rear engagement plane 311 of the front body shell 107 (see fig. 3I-1 for details) such that no relative up-and-down movement is possible between the front body shell 107 and the rear body shell 108. When the driving shaft 330 rotates in the second rotation direction (e.g., counterclockwise), the pawl 331 dials the locking slider 324 to the release position, so that the locking pressing block 314 can be withdrawn from the second locking window 322.

As shown in fig. 3D-3, the head of the locking slider 324 houses a trolley terminal block 385 with a plurality of front contact pins 386 integrated into the trolley terminal block 385 and the trolley terminal block 385 has a rear trolley contact plane 390. The front contact pins 386 are resiliently mounted to ensure effective electrical contact. The front end of the front stylus 386 protrudes outside the rear car contact plane 390. The rear end of the front contact pin 386 is connected to a plurality of rear conductors 231 as shown in fig. 3D-2. The trolley terminal block 385 with the front contact pins 386 constitutes the rear body wire connection device 221 described above. The rear body wire connecting device 221 is received by the locking slider 324 and moves with the locking slider 324, thereby achieving connection and disconnection of the rear body wire connecting device 221 from the front body wire connecting device 201. The locking slide 324 is also provided with identical guide ribs 327, 329 on both sides as shown in fig. 3D-2. The guide rib 327 is inserted into the guide groove 337 provided on the inner wall of the locking mechanism cavity 310 and the window covering 150 (see the guide groove 337 on the window covering 150 shown in fig. 3G, the guide groove on the inner wall is not shown) so that the locking slider 324 can be smoothly and accurately inserted into the groove of the connecting plate 361 when sliding, to achieve the contact connection of the rear body wire connecting device 221 with the front body wire connecting device 201.

A bushing is also provided between the front body sleeve 107 and the rear body sleeve 108 according to an embodiment of the present invention, and fig. 3F shows a perspective view of the bushing of the present invention. In the present invention, the front body cover 107 and the rear body cover 108 are both made of metal materials, and wear is large when they are directly nested, so that a plastic or rubber bushing, such as the bushing 340 shown in the figure, is added between them. As shown in fig. 3F, the shape and size of the bushing 340 matches the shape of the inner cavity 306 of the rear body cover 108 (and also matches the shape of the outer wall of the front body cover 107), the bushing 340 is generally cylindrical and tubular, but one side wall is a planar bushing engagement flat surface 341, the bushing engagement flat surface 341 matching the shape of the front side engagement flat surface 308 of the rear body cover 108.

To facilitate the interaction of the locking tab 314 and the locking slide 324 with the front body cover 107, a bushing through hole 342 is provided in the bushing engagement plane 341, the bushing through hole 342 being shaped and positioned to correspond to the second engagement window 322, and the locking slide 324 being pushed out of the bushing through hole 342 into contact with the front body cover 107. The bushing engagement plane 341 is further provided with a hinge curtain 343, and the upper end of the hinge curtain 343 is integrally connected with the bushing 340, so that the hinge curtain 343 can slightly swing around its upper end with the locking press 314 at a small angle. The hinge curtain 343 is positioned corresponding to the first engagement window 318 and is disposed between the locking press 314 and the rear engagement surface 311 of the front body cover 107, and the locking press 314 is pressed against the rear engagement surface 311 of the front body cover 107 by the hinge curtain 343 to enhance friction.

FIGS. 3H-1 and 3H-2 illustrate the faucet of the present invention and its internal structure. Wherein FIG. 3H-1 is a perspective view of the structure of the faucet shank of the present invention, showing the components inside the faucet shank in perspective. Fig. 3H-2 is an exploded view of the structure of the tap lever of the present invention.

As shown in fig. 3H-1 and 3H-2, the faucet lever 103 includes a tubular lever 109 having a hollow interior, the lower end of the faucet lever 103 is coupled to a front body cover 107, and the upper end of the faucet lever 103 has a telescoping portion 105 coupled to the tubular lever 109. As shown in fig. 1A, the upper end of the telescoping portion 105 is connected to a faucet portion 116. The telescoping portion 105 can be inserted into the tubular lever 109 or pulled out of the tubular lever 109, thereby enabling the length of the tap lever 103 to be adjusted to reduce the folded length of the two-wheeled electric vehicle 100. The interior of the tubular wand 109 accommodates a front wire 211, one end of the front wire 211 being connected to the tap portion 116 and the other end being connected to a front vehicle body wire connection device 201 (described in detail below) provided in the front vehicle body cover 107. Accordingly, to accommodate the length adjustability of the faucet shank 103, the front wire 211 has a telescoping screw 387 to change the length of the front wire 211 as the length of the faucet shank 103 changes. Providing the retractable front wire 211 inside the faucet bar 103 can avoid excessively long wires from being formed when the two-wheeled electric vehicle 100 is folded, and thus, the two-wheeled electric vehicle is wound around the vehicle body, which is difficult to fold, as compared with providing a non-retractable (but long enough) wire outside the faucet bar 103. As mentioned previously, to achieve connection of the front wire 211 inside the tap lever 103 with the rear wire 231 inside the rear vehicle body 102, front and rear vehicle body wire connection devices 201 and 221 are provided inside the front and rear vehicle body jackets 107 and 108, respectively, to achieve signal and power conduction when the front and rear vehicle body jackets 107 and 108 are locked.

In addition, as described above, the front conductor 211 is a cable with multiple conductors, which can transmit multiple signals or power.

The tap lever 103 further includes a tap shaft 106 connected to the lower end of the tubular lever 109, and the tap lever 103 is connected to the front body cover 107 via the tap shaft 106 at the lower end. The upper end of the tap shaft 106 is fixedly fitted inside the tubular lever 109, and the lower end of the tap shaft 106 is fitted inside the front body cover 107. The front body cover 107 is connected to the lower end of the faucet shaft 106 at both ends thereof via bearings 352 and 354, so that the front body cover 107 is movably mounted on the faucet lever 103 so as to be rotatable relative to the faucet lever 103.

A steering limiter 350 is attached to the lower end of the faucet shaft 106. Fig. 3J shows a perspective structure of the steering limiter 350. As shown in fig. 3J, the steering stopper 350 is provided with a steering stopper groove 357, and the steering stopper groove 357 extends along the circumferential direction of the tap shaft 106 and covers a range of the circumferential direction of the tap shaft 106. It can also be seen that the steering limiter 350 is a semi-annular structure that can be secured to the faucet shaft 106 by fasteners.

When the tap shaft 106 is fitted inside the front body cover 107, the steering limiter 350 is located inside the front body cover 107. The purpose of the steering limiter 350 having the steering limit groove 357 is to limit the rotation angle of the front body cover 107 with respect to the tap lever 103. In order to achieve this, in addition to the steering stopper 350 having a steering stopper groove, a stopper pin 351 is provided, which cooperates with the steering stopper groove 357, and the stopper pin 351 is in the form of a bolt having a nut at one end. A position on the front body cover 107 corresponding to the steering limit groove 357 is provided with a limit pin hole 355 (see fig. 3I-1 for details), and an end of the limit pin 351 opposite to the nut is inserted into the limit pin hole from the outside of the front body cover 107 and enters the limit groove after passing through the limit pin hole 355. The stop pin 351 thus cooperates with the stop slot to limit the rotation angle of the front body sleeve 107 relative to the tap lever 103 within the extension of the steering stop slot, whereas the rear body sleeve 108 also rotates relative to the tap lever 103 within the angular range defined by the extension of the steering stop slot, as the front body sleeve 107 and the rear body sleeve 108 can be fixedly connected together. The angle range is a steering angle range of the two-wheeled electric vehicle 100, and is approximately 48 degrees.

The lower end of the tap shaft 106 is further sleeved with a plurality of brush slip rings 365, the plurality of brush slip rings 365 being spaced apart from each other, each brush slip ring 365 being connected to one of the signal or power wires of the front conductor 211, respectively, and a surface of the brush slip ring 365 being adapted to electrically contact a rear contact pin 326 (the front body conductor connection 201 and its rear contact pin 326, which will be described later in detail with reference to fig. 3I-3 and 3I-4) of the front body conductor connection 201 to connect the front conductor 211 to the front body conductor connection 201. When the tap shaft 106 is fitted inside the front body cover 107, the brush slip ring 365 is located inside the front body cover 107. Since the rear vehicle body 102 can rotate relative to the front vehicle body 101 within the range defined by the steering stopper 350 to achieve steering of the two-wheeled electric vehicle, in order to ensure electric communication and signal communication between the rear vehicle body 102 and the front vehicle body 101 during steering, each brush slip ring 365 also extends along the circumferential direction of the tap shaft 106 as the steering stopper groove 357, and the extending range of the brush slip ring 365 is also substantially the same as that of the steering stopper groove 357. Furthermore, each brush slip ring 365 has a surface over its extension that can be electrically connected to the rear contact pin 326.

The mating relationship of the steering limit groove 357 to the limit pin 351, and the mating relationship of the rear contact pin 326 to the brush slip ring 365 can also be seen in fig. 3K, which omits the front body sleeve 107 and the connecting plate 361, which will be described in detail later, for clarity.

The specific construction of the front body cover 107 and the front body wire connection 201 mounted to the front body cover 107 will now be described in connection with FIGS. 3H-2,3I-1,3I-2,3I-3 and 3I-4. Fig. 3I-1 and 3I-2 are perspective structural views of the front body cover of the present invention, and fig. 3I-3 and 3I-4 are front and rear structural exploded views of the front body wire connecting device 201 of the present invention, respectively.

As shown in fig. 3I-1 and 3I-2, the front body cover 107 is generally cylindrical with an interior cylindrical cavity 111 therein, and the faucet shaft 106 is received within the cylindrical cavity 111. One side of the front body cover 107 is the aforementioned rear engagement plane 311, and the rear engagement plane 311 is provided with the front body wire connection device 201. The front body wire connection device 201 may be integrally formed with the front body cover 107 or may be formed separately as in the case shown in fig. 3H-2. Specifically, as shown, the rear engagement surface 311 of the front body cover 107 is provided with an opening 321 for receiving the front body wire connecting device 201, the opening 321 being positioned opposite to the brush slip ring 365 mounted on the tap shaft 106 inside the front body cover 107, and the front body wire connecting device 201 being mounted in the opening 321 so that the front body wire connecting device 201 can be electrically connected to the brush slip ring. A limit pin hole 355 for receiving the limit pin 351 is provided above the opening 321.

As shown in fig. 3I-3 and 3I-4, the front car body wire connection device 201 includes a connection plate 361, a front car contact plane 363 is provided on the connection plate 361, a plurality of contacts 362 are provided on the front face of the front car contact plane 363, and the rear contact pins 326 are in conductive communication with the plurality of contacts 362 from the rear face (back face) of the front car contact plane 363.

Specifically, the front surface of the connecting plate 361 is provided with the aforementioned groove 313 for receiving the front end of the inserted locking slider 324 to prevent the relative movement of the front body cover 107 and the rear body cover 108 in the vertical direction. The bottom of the groove 313 forms a front car contact plane 363, and a plurality of contacts 362 are provided in the front car contact plane 363 for contacting with a front contact pin 386 on a rear car contact plane 390 of the lock slider 324, so that the rear wire 231 in the rear car body 102 is connected with the front car wire 211 of the front car body, and the display device 204 in the front car body 101 is in signal and power communication with the control device 205 and the motor 224, the brake device 225, the power supply 223 and other components in the rear car body 102.

The back surface of the connecting plate 361 is provided with a back contact pin terminal block 389, and the back contact pin terminal block 389 is provided with a back contact pin 326 facing the inner cylindrical cavity 111 of the front body cover 107. The rear contact pin 326 is in contact with the brush slip ring 365 for electrical communication, and the rear contact pin 326 maintains sliding contact with the brush slip ring 365 as it rotates with the front body sleeve 107. The rear contact pin 326 is mounted within the rear contact pin terminal block 389 by a resilient structure that ensures that the rear contact pin 326 is always in resilient contact with the brush slip ring 365. The rear contact pin terminal block 389 may be integrally formed with the connection plate 361, or may be formed separately from the connection plate 361 as in the case shown in fig. 3I-3 and 3I-4, and detachably mounted on the connection plate 361.

In this embodiment, the brush slip ring 365 has four slip rings, with which 4 rows of rear contact pins 326 are provided, each row of rear contact pins 326 sliding on one brush slip ring 365, which is suitable for the design of 4 front conductors 211 and 4 rear conductors 231 in the first embodiment of the wiring structure shown in fig. 2A of the present invention. If the second embodiment of the wiring structure shown in fig. 2D has 1 front conductor 211 and 1 rear conductor 231, the brush slip ring 365 may have at least one slip ring, and the rear contact pins 326 may have at least one row of rear contact pins. In all embodiments, each row of rear contact pins 326 may be provided with two rear contact pins, and the two rear contact pins 326 conduct a signal at the same time and slide on a brush slip ring 365 at the same time, so as to form redundant electrical connection, and ensure effective conduction of the signal.

The rear contact pins 326 are wired to the contacts 362 via circuit boards within the connection plate 361 so that each signal is also communicated to the front contact pins 386 of the lock slide 324 via the plurality of contacts 362 to ensure effective communication of the wiring in the front body 101 and rear body 102 of the two-wheeled electric vehicle 100.

To further illustrate the wiring structure of the present invention, fig. 3M-1 and 3M-2 show a side sectional view and a front structural view, respectively, of the rear body of the two-wheeled electric vehicle of the present invention. As can be seen in fig. 3M-1, the front contact pin 386 in the lock slide 324 is connected to the rear wire 231, and the rear wire 231 passes through the interior of the support bar 104 and then enters the interior of the rear vehicle body 102 from the aperture 388 at the front end of the rear vehicle body 102 to be connected to the second control circuit 222 of the rear vehicle body 102. The aperture 388 at the front end of the platform-type rear frame 115 of the rear body 102 can be seen in fig. 3M-2.

In addition, a similar structure to the front body cover 107 may be provided at the upper end of the tap lever 103, so that the locking of the rear body to the front body can be achieved by the structure, the rear body cover 108 and the locking mechanism 320 when the rear body cover 108 is moved to the upper end of the tap lever 103 (i.e., when the folded position is reached). The locking does not need to be communicated with the circuit structure of the front car body and the rear car body, and only the front car body and the rear car body are locked in a folding state, so that the electric car is more convenient to carry.

The process of mechanically locking and electrically connecting the front body 101 and the rear body 102 for driving the two-wheeled electric vehicle, and mechanically releasing and electrically separating the front body 101 and the rear body 102 for folding the two-wheeled electric vehicle will be described below with reference to fig. 3L-1 and 3L-2. Fig. 3L-1 and 3L-2 are sectional views of the front vehicle body 101 and the rear vehicle body 102 of the present invention when mechanically released and electrically separated, and mechanically locked and electrically connected, respectively. For clarity, only the structure at the location of the front body cover 107 and the rear body cover 108 is shown in these two figures.

In order to drive a two-wheeled electric vehicle, it is first necessary to mechanically lock and electrically connect the front vehicle body 101 and the rear vehicle body 102. As mentioned previously, the mechanical locking and electrical connection, and mechanical release and electrical separation of the front body 101 and the rear body 102 are achieved by locking and releasing the front body cover 107 and the rear body cover 108 with the locking mechanism 320. To do so, the trigger mechanism 130 is first twisted to face the vertical direction, and the trigger mechanism 130 rotates the drive shaft 330 clockwise, thereby driving the locking press 314 and the locking slide 324 into their locking positions (shown in fig. 3L-2) that interact with the front car body cover 107, where the locking mechanism 320 effects mechanical locking and electrical connection of the front car body 101 and the rear car body 102.

In order to fold the two-wheeled electric vehicle, the pulling mechanism 130 is first turned to face the horizontal direction, and the pulling mechanism 130 drives the driving shaft 330 to rotate counterclockwise, so as to drive the locking pressing block 314 and the locking sliding block 324 into their release positions (as shown in fig. 3L-1) separated from the front vehicle body sleeve 107, where the mechanical locking of the front vehicle body 101 and the rear vehicle body 102 is released, and the electric connection is separated, so that the folding of the two-wheeled electric vehicle can be achieved.

Although the invention has been described with reference to the specific embodiments shown in the drawings, it should be understood that various changes can be made in the various mechanisms of the invention and the various embodiments of the invention can be combined with one another to form solutions not described in detail in the specification of the invention without departing from the spirit and scope and the background of the teachings of the invention. Those of ordinary skill in the art will also recognize that there are different ways to alter the parameters, such as the size, shape, type of elements or materials, in the disclosed embodiments of the invention, which fall within the spirit and scope of the invention and the claims.
