This embodiment proposes an electric vehicle 1, for example, a carrying tool moving on a track 9 or other road surface, which can be used to carry people, tools, and goods, etc., and thus can be used as a construction vehicle or truck. However, the present invention is not based on this. Limited.

As shown in the figure, the electric vehicle 1 includes a frame 110, four wheel bodies 120, a motor 130, a seat 140a1, a seat 140a2, a steering mechanism 150a, a steering mechanism 150b, a controller 160, A console 170 and two battery boxes 180.

The wheel bodies 120 are coupled to the left and right sides of the frame 110 in pairs, so that the frame 110 can be disposed on the track 9 via the wheel body 120. However, the present invention is not limited to the structure of the track 9 and the number of wheel bodies 120. For example, in other embodiments, the track 9 may be changed to other types of tracks, and the number of the wheel bodies 120 may be adjusted according to the design of the track and the frame. .

The electric motor 130 is mounted on the frame 110 and can be connected through a transmission mechanism (not labeled) and drives the wheel body 120 to rotate. In this embodiment, the motor 130 can rotate in the opposite direction according to the received electric signal to change the rotation direction of the wheel body 130, and then change the running direction of the electric vehicle 1.

The seat 140a1 and the seat 140a2 are juxtaposed on the frame 110, and among these two seats, the seat 140a1 is a driver's seat and the seat 140a2 is a front passenger seat. In this embodiment, the steering mechanism 150a is connected between the driver's seat 140a1 and the frame 110, and the steering mechanism 150b is connected between the passenger's seat 140a2 and the frame 110. The driver's seat 140a1 and the passenger's seat 140a2 can be movably disposed on the frame 110 via the steering mechanism 150a and the steering mechanism 150b, respectively, and can be rotated relative to the frame 110 toward the first direction D1 or the second direction D2 or other directions. The first direction D1 and the second direction D2 described herein refer to directions in which the driver's seat 140a1 or the passenger's seat 140a2 faces. In addition, it is reminded that the front passenger seat 140a2 and the steering mechanism 150b are selected and have similar structures to the driver seat 140a1 and the steering mechanism 150a, respectively.

The controller 160 is disposed on the frame 110, and can be electrically connected to the motor 130, the console 170, and the battery box 180 to transmit signals with the motor 130, the console 170, and the battery box 180.

The console 170 is fixed to the driver's seat 140a1, and can be rotated relative to the vehicle frame 110 along with the driver's seat 140a1. In this embodiment, the console 170 is a device equipped with a handle (not labeled), a display panel (not labeled), and a gear switching unit (not shown). The handle can be held and rotated by the driver to drive the vehicle. . The display panel can display the information of the electric vehicle 1 to the user. The gear switching unit may be, but is not limited to, a double-cut button switch, which is adapted to send a forward signal and a backward signal to the controller 160. However, it is reminded that the gear switching unit may also be a virtual button integrated into the display panel. In addition, the design of the control platform 170 is not limited to this. For example, in other embodiments, the control platform 170 may be replaced with an operation lever that can be dialed back and forth, and the vehicle is operated by pushing or pulling the operation lever forward. Or, the console 170 may be omitted and the aforementioned gear switching unit may be set on the driver's seat 140a1.

The battery box 180 is disposed on the frame 110, and a battery (not shown) is disposed therein, which can provide electric power required for the components such as the motor 130, the controller 160, and the console 170 to operate. However, it should be stated that the present invention is not limited to the number of the battery box 180 and the batteries therein. As long as the basic operation of the electric vehicle can be maintained, the number of these components can be increased or decreased as required.

Next, please refer to FIGS. 3 to 4. FIG. 3 is a partially enlarged view of the electric vehicle of FIG. 2, and FIG. 4 is a partially enlarged exploded view of the electric vehicle of FIG. 2. It is worth noting that, in this embodiment, the electric vehicle 1 further includes a first signal switch 181 and a second signal switch 182 provided in the steering mechanism 150a, which can be used as the controller 160 to change the rotation of the output shaft of the motor 130 One of the factors determining the direction.

Specifically, the steering mechanism 150a includes a first member 151, a second member 152, an elastic member 153, and a positioning module 154.

The first member 151 includes a base 1511 and a stop portion 1512. The base 1511 is fixed on the frame 110, and the stop portion 1512 protrudes from the surface of the base 1511 away from the frame 110. The base 1511 has a positioning groove 15111 and a positioning groove 15112, which are located on opposite sides of the base 1511, and the openings of the positioning groove 15111 and the positioning groove 15112 are located on one side of the base 1511 facing the driver's seat 140a1. The blocking portion 1512 has a first blocking surface 15121 and a second blocking surface 15122, which are located on opposite sides of the blocking portion 1512, respectively. The positioning groove 15111 and the positioning groove 15112 are adjacent to the first stop surface 15121 and the second stop surface 15122, respectively. The first signal switch 181 and the second signal switch 182 are electrically connected to the controller 160 and are respectively disposed on the first stop surface 15121 and the second stop surface 15122 of the stop portion 1512.

The second member 152 includes a base 1521, a rotation pivot 1522 and a positioning post 1523. The base 1521 is fixed below the driver's seat 140a1, and the rotation pivot 1522 and the positioning post 1523 extend from the base 1521 toward the first member 151 and maintain a distance from each other. The rotation pivot 1522 passes through the base 1511 of the first member 151. In addition to the rotation pivot 1522 being able to pivot relative to the base 1511, the rotation pivot 1522 can also perform linear movements toward or away from the frame 110 with respect to the base 1511. Therefore, the driver's seat 140a1 can The rotary pivot 1522 is pivoted relative to the frame 110 or makes a linear movement toward or away from the frame 110. The positioning post 1523 may be selected to abut the first stop surface 15121 or the second stop surface 15122 of the stop portion 1512 during the rotation of the driver seat 140a1. Wherein, when the positioning post 1523 abuts against the first stop surface 15121 of the stopping part 1512, the positioning post 1523 can trigger the first signal switch 181 and its position corresponds to the positioning groove 15111 of the base 1511; When the second stop surface 15122 of the stop portion 1512 is located, the positioning post 1523 can trigger the second signal switch 182 and its position corresponds to the positioning groove 15112 of the base 1511. In addition, since the stopper portion 1512 of the steering mechanism 150a can stop the positioning post 1523, the stopper portion 1512 can limit the driver's seat 140a1 relative to the frame while the driver's seat 140a1 is turned to the first direction D1 or the second direction D2. The rotation range of 110, if it can only be rotated 180 degrees in a single direction, thereby avoiding the problem that the driver ’s seat 140a1 or the lines associated with it are excessively pulled or broken when the driver ’s seat 140a1 is rotated substantially occur.

The elastic member 153 is a spring, which is sandwiched between the base 1521 of the second member 152 and the base 1511 of the first member 151 and is penetrated by the rotation pivot 1522 of the second member 152. The elastic member 153 can normally generate an elastic force on the driver's seat 140a1 via the second member 152 to push the driver's seat 140a1 away from the frame 110. By selecting the appropriate elastic member 153, when the driver's seat 140a1 is loaded, if the passenger applies his weight to the driver's seat 140a1, the passenger can overcome the elastic force of the elastic member 153 by his weight, forcing the driver's seat 140a1 to approach the vehicle. The direction of the rack 110 is displaced.

In addition, in design, the length of the positioning post 1523 is approximately equal to the distance between the base 1521 and the base 1511 when the driver's seat 140a1 is not loaded. Therefore, when the positioning post 1523 has not abutted against the first stop surface 15121 or the second stop surface 15122, even if the driver's seat 140a1 is loaded, the driver's seat 140a1 will not be able to approach the frame because the driver 15a is pressed against the base 1511. Displacement in the direction of 110; and when the positioning post 1523 abuts the first stop surface 15121 or the second stop surface 15122 so that the position of the positioning post 1523 corresponds to the positioning groove 15111 or 15112, the positioning post 1523 will follow the loaded driver's seat 140a1 is displaced toward the frame 110 and inserted into the positioning groove 15111 or the positioning groove 15112 to achieve the effect of positioning the driving seat 140a1. As shown in FIG. 5, the positioning column 1523 of FIG. 2 is inserted into the positioning with the weighted driving seat 140a1 A partially enlarged schematic view of the groove 15111. Therefore, the positioning slot 15111, the positioning slot 15112, and the positioning post 1523 constitute the positioning module 154.

Next, as an example of the use situation, please refer to Figs. 6-7, which are schematic side views of the operation of the electric vehicle of Fig. 1. Among them, for the convenience of description, Fig. 6-7 omit the front passenger seat 140a2 and its steering. Agency 150b. First, as shown in FIG. 6, when the driver's seat 140a1 faces the first direction D1, for a driver who wants to ride, the forward direction is the first direction D1, and the backward direction is the second direction D2. According to the foregoing description, in this case, the positioning post 1523 abuts the first stop surface 15121 of the stop portion 1512 to trigger the first signal switch 181 but not the second signal switch 182. Therefore, if the driver wants to move the electric vehicle 1 along the track 9 in the first direction D1 (forward direction), the driver can send a forward signal to the controller 160 via the gear switching unit of the console 170, so that the controller 160 causes the motor The output shaft (not labeled) of 130 is rotated in the first rotation direction (as shown by the solid line in the figure) to drive the electric vehicle 1 to move in the first direction D1. Conversely, if the driver wants to move the electric vehicle 1 along the track 9 to the second direction D2 (backward direction) when the driver's seat 140a1 is facing the first direction D1, he can use the gear switching unit of the console 170 to The controller 160 sends a back signal so that the controller 160 causes the output shaft of the motor 130 to rotate in the second rotation direction (as shown by the dotted line in the figure) to drive the electric vehicle 1 to move in the second direction D2. The first rotation direction is opposite to the second rotation direction.

Next, as shown in FIG. 7, if the driver wants to steer the electric vehicle 1, he can get up and rotate the driver's seat 140 a 1 180 degrees by the steering mechanism 150 a to face the second direction D 2. When the driver's seat 140a1 faces the second direction D2, for the driver, the forward direction becomes the second direction D2, and the backward direction becomes the first direction D1. It can be known from the foregoing description that the positioning post 1523 changes to abut the second stop surface 15122 of the stop portion 1512 and triggers the second signal switch 182 instead of the first signal switch 181. Therefore, at this time, if the driver wants to move the electric vehicle 1 along the track 9 in the second direction D2 (forward direction), the forward signal is also sent to the controller 160 via the gear switching unit of the console 170, but at this time the control The device 160 is changed so that the output shaft of the motor 130 is rotated in the second rotation direction (as shown by the solid line in the figure), and the wheel body 120 is driven to move the electric vehicle 1 in the second direction D2. Conversely, if the driver wants to move the electric vehicle 1 along the track 9 in the first direction D1 (reverse direction), the driver 160 also sends a back signal to the controller 160 via the gear switching unit of the console 170, but the controller 160 will cause the output shaft of the motor 130 to rotate in the first rotation direction (as shown by the dotted line in the figure), and the driving wheel body 120 will drive the electric vehicle 1 to move in the first direction D1.

It can be seen that the operation of the electric vehicle 1 during steering is convenient, and the user only needs to get up and rotate the seat to position, which solves the traditional problem that a person needs to use a jack to lift the entire vehicle and then rotate the vehicle body manually. Problems, reducing manpower consumption and the probability of generating work safety.

In addition, the controller can automatically determine the direction currently facing the driver according to the state of the signal switch to adaptively adjust the rotation direction of the output shaft of the driving motor. Therefore, even if the driver's seat is turned, the driver can continue to operate the electric vehicle with the same operating habits. In other words, the driver does not need to remember the corresponding relationship between the vehicle and the motor after the steering, and can avoid the problem of work safety caused by artificially issuing forward / backward signals.

Next, please refer to FIGS. 8 to 9. FIG. 8 is a schematic diagram of the electrical connection of the electric vehicle of FIG. 1, and FIG. 9 is a flowchart of a control method of the electric vehicle of FIG. 1. The control method of the aforementioned electric vehicle 1 will be explained below to more specifically understand the relationship between the controller and related components when the seat is turned.

Generally, in this embodiment, the electric vehicle 1 further includes a forward / reverse gear position sensor 161 electrically connected to the controller 160 to receive the forward signal and the reverse signal of the gear switching unit. In addition, when the first signal switch 181 is triggered, the first signal switch 181 sends a first trigger signal to the controller 160, and when the second signal switch 182 is triggered, the second signal switch 182 sends a second trigger signal to the control器 160。 160. In this way, the controller 160 can learn the conditions of the first signal switch 181 and the second signal switch 182 being triggered, and can also use the signal sent by the gear shift unit as a judgment of the rotation direction of the output shaft of the drive motor 130 in accordance with. It can also be said that the state of the signal received by the controller 160 can control the rotation direction of the output shaft of the motor 130 accordingly.

In detail, starting at step S01, it is determined that the forward / reverse gear position sensor 161 receives a forward signal or a reverse signal. If it is determined that the forward / reverse gear position sensor 161 receives the forward signal, it proceeds to step S02 to determine whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, go to step S03 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is also triggered, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 is invalid. Then, in step S04, the controller 160 sends an error signal to the console 170 to report the error condition. Give back to the driver.

If it is determined in the foregoing step S03 that the second signal switch 182 is not triggered, it can be determined that the position of the driver's seat 140a1 is facing the first direction D1 (that is, as shown in FIG. 6). Then, in step S05, the controller 160 causes the output shaft of the motor 130 to The first rotation direction rotates to drive the electric vehicle 1 in a first direction D1 facing the driver's seat 140a1.

If it is determined in the foregoing step S02 that the first signal switch 181 is not triggered, it proceeds to step S06 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is triggered, it can be determined that the driver's seat 140a1 is facing the second direction D2 (that is, as shown in FIG. 7). Then, in step S07, the controller 160 rotates the output shaft of the motor 130 in the second rotation direction, The electric vehicle 1 is driven to advance in the second direction D2 facing the driver's seat 140a1.

If it is determined in the foregoing step S06 that the second signal switch 182 has not been triggered, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 has failed, or that the driver's seat 140a1 is not yet positioned and the correct signal switch is not triggered. Based on safety considerations, the process proceeds to step S08, and the controller 160 sends an error signal to the console 170 to feedback the situation to the driver.

If it is determined in the foregoing step S01 that the forward / reverse gear position sensor 161 receives the reverse signal, it proceeds to step S09 to determine whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, it proceeds to step S10 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is also triggered, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 has failed, then go to step S11, the controller 160 sends an error signal to the console 170 to feedback the error situation To the driver.

If it is determined in the foregoing step S10 that the second signal switch 182 is not triggered, it can be determined that the position of the driver's seat 140a1 is facing the first direction D1 (that is, as shown in FIG. 6). Then, in step S12, the controller 160 causes the output shaft of the motor 130 to The second rotation direction rotates to drive the electric vehicle 1 to move in the second direction D2.

If it is determined in the foregoing step S09 that the first signal switch 181 is not triggered, it proceeds to step S13 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is triggered, it can be judged that the position of the driver's seat 140a1 is facing the second direction D2 (as shown in FIG. 7). Then, in step S14, the controller 160 rotates the output shaft of the motor 130 in the first rotation direction , To drive the electric vehicle 1 to move in the first direction D1.

If it is determined in the foregoing step S13 that the second signal switch 182 is also not triggered, it may be determined that at least one of the first signal switch 181 and the second signal switch 182 is disabled, or the driver ’s seat 140a1 is not yet positioned and the correct signal switch is not triggered. Based on safety considerations, go to step S15, the controller 160 sends an error signal to the console 170 to report the situation to the driver.

Understandably, the driver cannot drive the motor 130 when the first trigger signal and the second trigger signal are triggered at the same time or neither is triggered (that is, when an error signal is received). In addition, it should be stated that the present invention is not limited to the determination order of the forward / reverse gear position sensor 161, the first signal switch 181, and the second signal switch 182 in FIG.

In addition, as shown in FIG. 8, in addition to the aforementioned forward / reverse gear position sensor 161, the electric vehicle 1 further includes an accelerator opening sensor 162 and a battery sensor electrically connected to the controller 160.测 器 163 and a brake sensor 164. The accelerator opening sensor 162 can send an accelerator opening signal to the controller 160 according to the degree of the driver turning the handle, so that the controller 160 can adjust the rotation speed of the output shaft of the motor 130 according to the accelerator opening signal. The battery sensor 163 can detect the power storage or temperature status of the battery box 180. The brake sensor 164 can be used to detect a braking condition of the vehicle.

In addition, please refer to FIGS. 1 to 2 and refer to FIGS. 10 to 11 again. FIGS. 10 to 11 are schematic side views of the operation of the brake mechanism of FIG. 1. In this embodiment, the electric vehicle 1 further includes a braking mechanism 190. However, it needs to be stated that, for the purpose of clarity, only one of the wheel bodies 120 is shown in FIGS. 10 to 11.

In this embodiment, the brake mechanism 190 is coupled to the driver's seat 140a1 via the rotation pivot 1522 of the steering mechanism 150a, and can separately contact the wheel body 120. The braking mechanism 190 is mainly composed of a cable member 191 and a braking device 192. The braking device 192 is installed inside the wheel body 120. The cable member 191 is, for example, a steel cable, which has a seat end 1911 and a brake end 1912 opposite to each other. The seat end 1911 is hooked on the rotation pivot 1522 of the steering mechanism 150a to move up and down with the rotation pivot 1522. The braking end 1912 is hooked on the braking device 192 to drive the braking device 192.

As shown in FIG. 10, when the driver's seat 140a1 is not loaded, for example, after the driver gets up, the driver's seat 140a1 can be pushed away by the elastic force of the elastic member 153 and is slightly away from the frame 110 because the driver no longer bears the weight, so that the rotation pivot 1522 is lifted upward to tighten the cable member 191, and then the brake device 192 is tightened, so that the brake device 192 clamps the wheel axle with a brake belt (not labeled) to prevent the wheel body 120 from continuing to rotate, that is, the brake on the wheel body 120 is generated. effect. This can avoid the work safety problem caused by accidentally sending the forward signal or the backward signal when the driver's seat 140a1 turns, instead of moving the electric vehicle 1 unexpectedly. As shown in FIG. 11, when the driver's seat 140a1 is loaded, for example, after the driver sits back in the driver's seat 140a1, the loaded driver's seat 140a1 will move slightly toward the frame 110, so that the rotation pivot 1522 is downwardly displaced and relaxed. The cable member 191 releases the braking effect of the braking device 192 on the wheel body 120.

Moreover, please refer to FIGS. 1 to 2 and refer to FIG. 12 again. FIG. 12 is a schematic diagram of the first lamp of FIG. 1. In this embodiment, the electric vehicle 1 further includes two first lamps 210 and two second lamps 220. The first lamp 210 and the second lamp 220 are electrically connected to the controller 160 and are installed on the front and rear sides of the frame 110 opposite to each other. Since the first light fixture 210 and the second light fixture 220 are similar in structure, FIG. 10 is only described with the first light fixture 210.

The first lamp 210 and the second lamp 220 each include a lamp body 200, a plurality of first light-emitting units 201, and a second light-emitting unit 202 surrounded by the first light-emitting unit 201. The lamp body 200 is movably disposed on the frame 110. The first light emitting unit 201 and the second light emitting unit 202 are disposed in the lamp body 200 and may be, but are not limited to, a light bulb or an LED lamp. The first light-emitting unit 201 and the second light-emitting unit 202 are respectively used to emit light of different colors, so that the first lamp 210 and the second lamp 220 can each have a front light mode and a rear light mode. The so-called headlight mode is, for example, a light-emitting mode generated when the first light-emitting unit 201 of the first lamp 210 or the second lamp 220 is turned on, but the second light-emitting unit 202 is turned off; and the back-light mode is, for example, the first lamp 210 or the first lamp 210. The first light-emitting unit 201 of the two lamps 220 is turned off, but the light-emitting mode generated when the second light-emitting unit 202 is turned on. However, the headlight mode and the rear light mode are not limited to this. For example, in other embodiments, the on / off status of the lighting unit of each lamp in the front light mode and the rear light mode can be designed according to actual needs. Arrangement of light emitting units. In addition, the present invention is not limited to the number and arrangement of the first light-emitting units 201 and the second light-emitting units 202, for example, in other embodiments, the number of the first light-emitting units 201 and the second light-emitting units 202 in each lamp The arrangement and arrangement can be adjusted according to actual needs.

In this embodiment, the mode switching of the first lamp 210 and the second lamp 220 is determined based on the triggering conditions of the first signal switch 181 and the second signal switch 182. Please refer to FIG. 13A, which is a flowchart of a control method of the first lamp and the second lamp of FIG.

First, in step S21, it is determined whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, go to step S22 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is also triggered, as described above, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 is invalid. Then, step S23 is performed, and the controller 160 sends an error signal.

If it is determined in the foregoing step S22 that the second signal switch 182 is not triggered, the process proceeds to step S24, and the controller 160 causes the first lamp 210 to switch to the front lamp mode and the second lamp 220 to switch to the rear lamp mode.

If it is determined in the foregoing step S21 that the first signal switch 181 is not triggered, it proceeds to step S25 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is triggered, the process goes to step S26, the controller 160 causes the first lamp 210 to switch to the rear lamp mode and causes the second lamp 220 to switch to the front lamp mode.

If it is determined in the foregoing step S25 that the second signal switch 182 has not been triggered, as described above, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 has failed, or the driver's seat 140a1 has not yet been positioned and has not been triggered correctly. Based on the safety considerations, the signal switch of step 2 goes to step S27, and the controller 160 sends an error signal.

It can be known that the first light fixture 210 and the second light fixture 220 adjust the light emitting mode according to the direction of the driver's seat 140a1 (that is, the direction the driver is currently facing), which helps the onlookers to understand the current state of the vehicle.

However, it is reminded that although the electric vehicle of the foregoing embodiment has lamps on the front and back sides, the present invention is not limited thereto. For example, in other embodiments, the electric vehicle may have only the first lamp 210 disposed on one side of the electric vehicle. In this case, the method for controlling a lamp may refer to FIG. 13B, which is a flowchart of a method for controlling a first lamp of an electric vehicle according to an embodiment of the present invention.

Beginning in step S31, it is determined whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, go to step S32 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is also triggered, as described above, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 has failed, then go to step S33, and the controller 160 sends an error signal.

If it is determined in the foregoing step S32 that the second signal switch 182 is not triggered, the process proceeds to step S34 and the controller 160 causes the first lamp 210 to switch to the headlight mode.

If it is determined in the foregoing step S31 that the first signal switch 181 is not triggered, it proceeds to step S35 to determine whether the second signal switch 182 is triggered. If the second signal switch 182 is triggered, the process proceeds to step S36, and the controller 160 causes the first lamp 210 to switch to the rear lamp mode.

If it is determined in the foregoing step S35 that the second signal switch 182 has not been triggered, as described above, it can be determined that at least one of the first signal switch 181 and the second signal switch 182 has failed, or the driver's seat 140a1 has not yet been positioned and has not been triggered correctly. If the signal switch is on, go to step S37, and the controller 160 sends an error signal.

Next, please refer to FIG. 14, which is a schematic diagram of an electric vehicle according to another embodiment of the present invention. This embodiment proposes an electric vehicle 2 that is different from the electric vehicle 1 of the previous embodiment in that the seat 240a1 and the seat 240a2 of the electric vehicle 2 are movably disposed on the frame through the same steering mechanism 250 230 on. In this case, the two seats can be rotated to the first direction D1 or the second direction D2 or other directions relative to the frame 230 at the same time. However, the design of the steering mechanism 250 is similar to the aforementioned steering mechanism 150a. Therefore, the description of the operation manner of the electric vehicle 2 in this embodiment and the like will not be repeated here.

For another example, please refer to FIGS. 15A to 15B, which are operation schematic diagrams of an electric vehicle according to another embodiment of the present invention. This embodiment proposes an electric vehicle 3, which differs from the electric vehicle 1 of the previous embodiment in the design of the driver's seat and the steering mechanism and the position of the signal switch.

As shown in the figure, in this embodiment, the seat 340 includes a seat cushion portion 341 and a seat back portion 342. The seat cushion portion 341 is fixed to the frame 310, and the seat back portion 342 is pivotally connected to the seat cushion portion 341 via the steering mechanism 350, so that the seat back portion 342 can swing relative to the seat cushion portion 341 via the steering mechanism 350 to switch the seat 340 to face the first direction D1 or second direction D2. In addition, in this embodiment, the positions of the first signal switch 181 and the second signal switch 182 are changed to the lower sides of the steering mechanism 350.

As shown in FIG. 15A, when the seat back 342 swings relative to the seat cushion portion 341 via the steering mechanism 350 toward the first direction D1, one end of the steering mechanism 350 relative to the seat back 342 will trigger the first signal switch 181; on the other hand, as shown in FIG. 15B, when the seat back 342 swings relative to the seat cushion portion 341 via the steering mechanism 350 and faces the second direction D2, the end of the steering mechanism 350 relative to the seat back 342 triggers the second signal switch 182. Therefore, it can be understood that this embodiment is similar to the manner in which the vehicle is operated in the foregoing embodiment, so please repeat it here.

In addition, the electric vehicle in the foregoing embodiment has two signal switches as one of the determining factors for the controller to change the rotation direction of the output shaft of the driving motor, but the invention is not limited thereto. For example, in other embodiments, the aforementioned electric vehicle may not have a second signal switch. In this case, please refer to FIG. 16, which is a flowchart of a control method of an electric vehicle according to still another embodiment of the present invention. The judgment method of the controller driving the motor is:

In step S41, it is determined whether the first signal switch is triggered. If the first signal switch is triggered, go to step S42 to determine whether the forward / reverse position sensor receives a forward signal or a backward signal. If it is determined that the forward / reverse position sensor receives a forward signal, go to step S43, the controller The output shaft of the motor is rotated in the first rotation direction to drive the electric vehicle to advance in the first direction facing the driver's seat. If it is judged in the foregoing step S42 that the forward / reverse gear position sensor receives the reverse signal, then to step S44, the controller causes the output shaft of the motor to rotate in the second rotation direction to drive the electric vehicle along the opposite side of the driver's seat. Move back in the first direction (that is, move the electric vehicle in the second direction).

If it is determined in the foregoing step S41 that the first signal switch is not triggered, go to step S45 and then determine that the forward / reverse position sensor receives the forward signal or the backward signal. If it is determined that the forward / reverse position sensor receives the forward signal, then To step S46, the controller causes the output shaft of the motor to rotate in the second rotation direction to drive the electric vehicle to advance in the second direction facing the driver's seat. If it is determined in the foregoing step S45 that the forward / reverse gear position sensor receives the reverse signal, then to step S47, the controller causes the output shaft of the motor to rotate in the first rotation direction to drive the electric vehicle along the opposite side of the driver's seat. Move back in the second direction (that is, move the electric vehicle in the first direction).

Here, please refer to FIG. 17, which is a flowchart of a control method of the first lamp of the electric vehicle of FIG. 16 to describe a method of the controller controlling the lamp in this embodiment.

First, in step S51, it is determined whether the first signal switch is triggered. If yes, go to step S52, the controller causes the first lamp to switch to the headlight mode. If not, go to step S53, the controller causes the first lamp to switch to the rear lamp mode.

Even in other embodiments, for example, the electric vehicle may not have the aforementioned second signal switch 182 and the gear switching unit. In this case, please refer to FIG. 18, which is a flowchart of a control method of an electric vehicle according to still another embodiment of the present invention to understand the control method of the controller in this embodiment. In step S61, it is determined whether the first signal switch is triggered. If yes, go to step S62, the controller makes the output shaft of the motor rotate in the first rotation direction; if not, go to step S63, the controller makes the output shaft of the motor rotate in the second rotation direction. It can be understood that the control method of the electric vehicle for the lamp according to the embodiment of FIG. 18 is similar to the control method of the electric vehicle for the lamp described in FIG. 17, so the details are omitted here.

In summary, the control method of the electric vehicle and the electric vehicle described above, through the design of the steering mechanism, makes the operation of the seat convenient when turning. The user only needs to get up and rotate the seat to position, which solves the traditional problem. The problem that the personnel need to use a jack to lift the whole vehicle and then rotate the car body by manpower reduces the manpower consumption and the probability of generating work safety.

In the operation of the steering process, the stopper can limit the rotation range of the seat relative to the frame. For example, it can only be rotated 180 degrees in a single direction, thereby avoiding the surrounding of the seat or the line that is associated with it. The problem of excessive pulling or breaking of the seat due to the large rotation of the seat occurs.

In addition, when the seat is facing different directions, the triggering condition of the signal switch can be changed by the steering mechanism, so that the controller can automatically determine the direction the driver is currently facing according to the state of the signal switch to adaptively adjust the output shaft of the driving motor. Direction, so even if the driver ’s seat is turned, the driver can continue to operate the electric vehicle with the same operating habits. It can also be said that the driver does not need to remember the corresponding relationship between the vehicle and the motor after turning, which can avoid the occurrence of work safety problems caused by human error of forward / backward signals.

At the same time, with the aforementioned safety mechanism, the controller will return an error to the driver when the signal switch fails, to avoid unexpected results and work safety problems when the component fails.

In addition, through the positioning module, the seat can reach the positioning effect due to the load when positioning, which helps maintain the state of the signal switch being triggered.

In addition, the brake mechanism can produce a braking effect on the wheel body when the seat is not loaded, which can avoid the driver's safety problems caused by accidentally sending a forward signal or a reverse signal when the seat is turned, instead of moving the electric vehicle unexpectedly.

Furthermore, switching the lighting mode of the lamp by changing the triggering condition of the signal switch helps the onlookers to know the current driving condition of the electric vehicle.
