Description

Electric vehicle

The present invention relates to a carrier, and more particularly to an electric vehicle.

Rail transportation is convenient and has a high single-load capacity. Whether it is passenger or transportation goods, it is more rapid, convenient and economical than general road transportation. It is the most efficient system known for land transportation. Therefore, rail transportation has not only become one of the important infrastructures in modern society, but has also been listed as a key development project in countries around the world.

In order to avoid the long-term train wear and tear and affect the driving safety, the inspection, maintenance, repair and replacement of the rails become more and more important. Usually, the maintenance or staff will take the track construction vehicle along the track route one by one. However, due to the limitation of the track, the construction vehicle cannot directly turn the steering head like a normal car. Therefore, the traditional method will attach a jack to the car. When the vehicle needs to be turned, the jack will be jacked up and then the whole car will be rotated 180 degrees by human force. However, because the weight of the railcar is heavier, it usually takes at least two people to complete the action of rotating the vehicle, and the human burden is heavy. In addition, the construction vehicle often carries a large number of tools or materials, which increases the difficulty of steering the vehicle. Not only that, this kind of attendance work is usually carried out at night or when it is difficult to rescue. The environment with insufficient light or high pressure is very likely to cause misoperation and cause work safety problems.

In view of this, the present invention provides an electric vehicle to solve the problem of steering of a vehicle in the prior art.

An electric vehicle according to an embodiment of the present invention includes a frame, at least one wheel body, an electric motor, a controller, a first signal switch, a steering mechanism, and One less seat. At least one wheel body is coupled to the frame. The motor is mounted to the frame. The motor is configured to drive the at least one wheel to rotate. The controller is electrically connected to the motor and is adapted to indicate that the motor is rotating. The first signal switch is electrically connected to the controller. The steering mechanism is movably disposed on the frame. At least one seat is disposed on the steering mechanism to be movable toward the first direction or the second direction via the steering mechanism relative to the frame. The steering mechanism triggers the first signal switch when the at least one seat faces the first direction. The steering mechanism does not trigger the first signal switch when the at least one seat faces the second direction. The direction of rotation of one of the output shafts of the motor is associated with whether the first signal switch is triggered.

The electric vehicle disclosed in the above, by the design of the steering mechanism, makes the operation of the seat convenient when the steering is performed, and the user only needs to get up and rotate the seat to the positioning, thereby solving the problem that the traditional personnel need to use the jack. The problem caused by the human body rotating the car body from the roof of the car reduces the labor consumption and the probability of generating safety.

Moreover, when the seat faces in different directions, the triggering condition of the signal switch can be changed by the steering mechanism, so that the controller can automatically determine the current direction of the driver according to the state of the signal switch to adaptively adjust the rotation of the output shaft of the driving motor. Direction, therefore, even if the driver's seat is turned, the driver can continue to operate the electric vehicle in 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 steering after the steering, and can avoid the problem of the work safety caused by the human error in the forward/reverse signal.

The above description of the disclosure and the following description of the embodiments are intended to illustrate and explain the spirit and principles of the present invention, and to provide further explanation of the scope of the patent application of the present invention.

Unless specifically defined, these terms are not to be construed as too idealistic or formal.

First, please refer to FIG. 1 to FIG. 2 , which are schematic perspective views of an electric vehicle according to an embodiment of the present invention.

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

As shown, 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 compartments 180.

The wheel bodies 120 are coupled to the left and right sides of the frame 110 in groups, 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 the wheel bodies 120. For example, in other embodiments, the track 9 can be changed to other forms of tracks, and the wheel body 120 can be adjusted according to the design of the track and the frame. .

The motor 130 is mounted on the frame 110 and is connectable and driven to rotate by the wheel body 120 via a transmission mechanism (not numbered). In the embodiment, the motor 130 can rotate in the opposite direction according to the received electrical signal to change the rotation direction of the wheel body 130, thereby changing the traveling direction of the electric vehicle 1.

The seat 140a1 and the seat 140a2 are juxtaposed on the frame 110, and in the two In the seat, the seat 140a1 is a driver's seat, and the seat 140a2 is a passenger's seat. In the present embodiment, the steering mechanism 150a is coupled between the driver's seat 140a1 and the frame 110, and the steering mechanism 150b is coupled between the passenger's seat 140a2 and the frame 110. The driver's seat 140a1 and the passenger's seat 140a2 are movably disposed on the frame 110 via the steering mechanism 150a and the steering mechanism 150b, respectively, and are rotatable relative to the frame 110 in 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 a direction in which the driver's seat 140a1 or the passenger's seat 140a2 faces. Further, it is noted that the passenger seat 140a2 and the steering mechanism 150b are optional and have a similar structure to the driver seat 140a1 and the steering mechanism 150a, respectively.

The controller 160 is disposed on the frame 110 and electrically connected to the motor 130, the console 170 and the battery case 180 for signal transmission with the motor 130, the console 170 and the battery case 180.

The console 170 is fixed to the driver's seat 140a1 and is rotatable relative to the frame 110 along with the driver's seat 140a1. In this embodiment, the console 170 is a device configured with a handle (not labeled), a display panel (not labeled), and a gear shifting unit (not shown). The handle is for the driver to hold and rotate to drive the vehicle. . The display panel can display information of the electric vehicle 1 to the user. The gear shifting unit can be, but is not limited to, a double-cut button switch, and is adapted to send a forward signal and a back signal to the controller 160. However, it is reminded that the gear shifting unit can also be a virtual button and integrated into the display panel. In addition, the design of the console 170 is not limited thereto. For example, in other embodiments, the console 170 can be replaced with a front and rear toggle lever, and the vehicle can be operated by pushing forward or pulling the lever backward. Alternatively, the console 170 may be omitted, and the aforementioned gear shifting unit may be disposed on the driver's seat 140a1.

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

Next, please refer to Figures 3~4, and Figure 3 is a partial enlargement of the electric vehicle of Figure 2. Figure 4 is a partially enlarged exploded view of the electric vehicle of Figure 2; It should be noted that, in this embodiment, the electric vehicle 1 further includes a first signal switch 181 and a second signal switch 182 disposed in the steering mechanism 150a, and 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 to the frame 110, and the stopping portion 1512 protrudes from the surface of the base 1511 away from the frame 110. The base 1511 has a positioning slot 15111 and a positioning slot 15112 respectively on opposite sides of the base 1511, and the opening of the positioning slot 15111 and the positioning slot 15112 is located on one side of the base 1511 toward the driver seat 140a1; The blocking portion 1512 has a first stopping surface 15121 and a second stopping surface 15122 respectively on opposite sides of the stopping portion 1512. The positioning groove 15111 and the positioning groove 15112 are respectively adjacent to the first stopping surface 15121 and the second stopping surface 15122. 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 stopping portion 1512.

The second member 152 includes a base portion 1521, a rotating pivot 1522 and a positioning post 1523. The base portion 1521 is fixed below the driver's seat 140a1, and the rotation pivot 1522 and the positioning post 1523 extend from the base portion 1521 toward the first member 151 and are kept at a distance from each other. The rotating pivot 1522 is disposed through the base 1511 of the first member 151. The pivot 1522 can be moved relative to the base 1511 to move away from or away from the frame 110, so that the driver seat 140a1 can be The linear motion of pivoting or pivoting relative to the frame 110 by the pivoting pivot 1522. The positioning post 1523 can be selected to abut against the first stop surface 15121 or the second stop surface 15122 of the stop portion 1512 as the driver seat 140a1 rotates. Wherein, when the positioning post 1523 abuts against the first stopping surface 15121 of the stopping portion 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; and when the positioning post 1523 abuts When the second stop surface 15122 of the stop portion 1512, the positioning post 1523 can trigger the second The signal switch 182 and its position corresponds to the positioning groove 15112 of the base 1511. Moreover, since the stopping portion 1512 of the steering mechanism 150a can stop the positioning post 1523, the stopping portion 1512 can restrict the driver seat 140a1 relative to the frame during the turning of the driver seat 140a1 into the first direction D1 or the second direction D2. The range of rotation of 110 can only be rotated 180 degrees in a single direction, thereby avoiding the problem of excessive pulling or tearing of the circuit around or between the driver's seat 140a1 as the driver's seat 140a1 is rotated greatly. occur.

The elastic member 153 is a spring that is interposed between the base portion 1521 of the second member 152 and the base 1511 of the first member 151 and is bored by the rotating pivot 1522 of the second member 152. The elastic member 153 can normally generate an elastic force to the driver's seat 140a1 via the second member 152 to push the driver's seat 140a1 away from the frame 110. By selecting a suitable elastic member 153, when the driver's seat 140a1 is loaded, if a passenger applies its weight to the driver's seat 140a1, the passenger can overcome the elastic force of the elastic member 153 by its weight, forcing the driver's seat 140a1 toward the vehicle. The direction of the frame 110 is displaced.

Moreover, 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 yet abutted against the first stop surface 15121 or the second stop surface 15122, even if the driver seat 140a1 is loaded, the driver seat 140a1 may not be approached to the frame due to the positioning post 1523 pressing against the base 1511. The direction of displacement of 110; and when the positioning post 1523 abuts the first stop surface 15121 or the second stop surface 15122 to position the positioning post 1523 corresponding to the positioning slot 15111 or 15112, the positioning post 1523 will follow the weight of the driver's seat The 140a1 is displaced toward the frame 110 and inserted into the positioning slot 15111 or the positioning slot 15112 to achieve the effect of positioning the driver's seat 140a1. As shown in FIG. 5, the positioning post 1523 of FIG. 2 is inserted and positioned with the weighted driver's seat 140a1. A partially enlarged schematic view of the slot 15111. Therefore, the positioning groove 15111, the positioning groove 15112 and the positioning post 1523 constitute the positioning module 154.

Next, as an example of using the situation, please refer to FIG. 6-7, which is a schematic side view of the operation of the electric vehicle of FIG. 1. For the purpose of convenience of description, FIG. 6-7 omits the passenger seat 140a2 and its steering. Mechanism 150b. First, as shown in FIG. 6, when the driver's seat 140a1 faces the first In one direction D1, for the driver to ride, the direction of advancement is the first direction D1, and the direction of retreat is the second direction D2. As can be seen from 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 does not trigger 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 forward signal can be sent to the controller 160 via the gear shifting unit of the console 170, so that the controller 160 makes the motor The output shaft (not numbered) of 130 is rotated in a first rotational direction (as indicated by the solid line in the drawing) to drive the electric vehicle 1 to move in the first direction D1. In reverse, if the driver wants to move the electric vehicle 1 along the track 9 in the second direction D2 (reverse direction) when the driver's seat 140a1 faces the first direction D1, the gear shifting unit can be operated via the console 170. The controller 160 transmits a back signal such that the controller 160 rotates the output shaft of the motor 130 in a second rotational direction (as indicated by the dashed line in the drawing) to drive the electric vehicle 1 to move in the second direction D2. Wherein, 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, it is possible to get up and rotate the driver's seat 140a1 by 180 degrees toward the second direction D2 by the steering mechanism 150a. When the driver's seat 140a1 faces the second direction D2, the forward direction becomes the second direction D2 for the driver, and the reverse direction becomes the first direction D1. As can be seen from the foregoing description, the positioning post 1523 is adapted to abut the second stop surface 15122 of the stop portion 1512 and trigger the second signal switch 182 without triggering the first signal switch 181. Therefore, 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 shifting unit of the console 170, but this time the control is performed. The device 160 is modified to rotate the output shaft of the motor 130 in the second rotational direction (as indicated by the solid line in the figure), and the drive wheel 120 drives the electric vehicle 1 to move in the second direction D2. In reverse, if the driver wants to move the electric vehicle 1 along the track 9 in the first direction D1 (reverse direction), the controller 160 also sends a back signal via the gear shifting unit of the console 170, but the controller 160 will rotate the output shaft of the motor 130 in the first direction of rotation (as indicated by the dashed line in the drawing), and drive the wheel body 120 to move the electric vehicle 1 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 the positioning, which solves the problem that the traditional personnel need to use the jack to lift the whole vehicle and then rotate the vehicle body by human power. The problem reduces the labor consumption and the chance of generating safety.

Moreover, the controller can automatically determine the direction that the driver is currently facing according to the state of the signal switch to adaptively adjust the rotation direction of the output shaft of the drive motor. Therefore, even if the driver's seat is turned, the driver can continue to operate the electric vehicle with the same operating habits. That is to say, the driver does not need to remember the corresponding relationship between the vehicle and the motor steering after the steering, and can avoid the problem of the work safety caused by the human error in the forward/reverse signal.

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 flow chart of the control method of the electric vehicle of FIG. The control method of the aforementioned electric vehicle 1 will be explained below to more specifically understand the relationship between the controller and the related elements when the seat is turned.

Generally, in the embodiment, the electric vehicle 1 further has a forward/reverse gear position sensor 161 electrically connected to the controller 160 for receiving the forward signal and the backward signal of the gear shifting 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. 160. Thereby, the controller 160 can know that the first signal switch 181 and the second signal switch 182 are triggered, and the signal sent by the gear shifting unit can be used as the judgment of the rotation direction of the output shaft of the driving motor 130. in accordance with. It can also be said that the state of the signal received by the controller 160 can control the direction of rotation 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 the forward signal or the backward signal. If it is determined that the forward/reverse gear position sensor 161 receives the forward signal, then to step S02, it is determined whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, then to step S03, it is determined whether the second signal switch 182 is triggered. If the second signal switch 182 is also triggered, it can be determined that the first signal switch 181 and the second signal switch 182 are at least If one of them fails, then to step S04, the controller 160 sends an error signal to the console 170 to feed back the wrong condition to the driver.

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

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

If the foregoing step S06 determines that the second signal switch 182 is also not triggered, it can 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 only yet positioned and does not trigger the correct signal switch. Based on the security considerations, then to step S08, the controller 160 sends an error signal to the console 170 to feed the situation back to the driver.

If the foregoing step S01 determines that the forward/reverse gear position sensor 161 receives the back signal, it proceeds to step S09 to determine whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, then to step S10, it is determined 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 disabled. Then, in step S11, the controller 160 sends an error signal to the console 170 to feedback the error. To the driver.

If the foregoing step S10 determines that the second signal switch 182 is not triggered, it can be determined that the driver's seat 140a1 is facing the first direction D1 (ie, as shown in FIG. 6), then to 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 the foregoing step S09 determines that the first signal switch 181 is not triggered, then the step In step S13, it is determined whether the second signal switch 182 is triggered. If the second signal switch 182 is triggered, the position of the driver's seat 140a1 toward the second direction D2 (ie, as shown in FIG. 7) can be determined. Then, to step S14, the controller 160 rotates the output shaft of the motor 130 in the first rotation direction. The electric vehicle 1 is driven to move in the first direction D1.

If the foregoing step S13 determines that the second signal switch 182 is also not triggered, it can 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 only yet positioned and does not trigger the correct signal switch. Based on the security considerations, then to step S15, the controller 160 sends an error signal to the console 170 to feed the situation back to the driver.

Understandably, the driver cannot drive the motor 130 when the first trigger signal and the second trigger signal are both triggered or not triggered (ie, when an error signal is received). In addition, it should be noted 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 foregoing forward/reverse position sensor 161, the electric vehicle 1 further has an accelerator opening sensor 162 electrically connected to the controller 160, and a battery sense. The detector 163 is coupled to a brake sensor 164. The accelerator opening sensor 162 can send an accelerator opening signal to the controller 160 according to the degree to which the driver turns the handle, so that the controller 160 can adjust the rotational speed of the output shaft of the motor 130 according to the accelerator opening signal. Battery sensor 163 can be used to detect the storage or temperature conditions of battery compartment 180. The brake sensor 164 can be used to detect the braking condition of the vehicle.

In addition, please refer to FIGS. 1~2 and FIG. 10~11 again, and FIG. 10-11 is a schematic side view of the operation of the braking mechanism of FIG. In the embodiment, the electric vehicle 1 further includes a brake mechanism 190. However, it should be noted that for the purpose of clear explanation, only one of the wheel bodies 120 is illustrated in FIGS.

In the present embodiment, the braking mechanism 190 is coupled to the driver's seat 140a1 via the rotating pivot 1522 of the steering mechanism 150a, and can separately contact the wheel body 120. The brake mechanism 190 is mainly composed of a cable member 191 and a brake device 192. The brake device 192 is mounted on the wheel body 120 Inside. The cable member 191 is, for example, a cable having a seat end 1911 and a brake end 1912 opposite to each other, and the seat end 1911 is hooked to the pivot pivot 1522 of the steering mechanism 150a to move up and down with the rotary pivot 1522. The brake end 1912 is hooked to the brake device 192 to drive the brake 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 against the frame 110 slightly by the elastic force of the elastic member 153 because it is no longer loaded, so that the pivot is pivoted. The 1522 is lifted up to tighten the cable member 191, thereby tightening the brake device 192, so that the brake device 192 clamps the axle with the brake belt (not labeled) to prevent the wheel body 120 from continuing to rotate, that is, the brake device 120 is braked. effect. Thereby, it is possible to avoid the safety problem caused by accidentally sending the forward signal or the reverse signal when the driver's seat 140a1 is turned instead of moving the electric vehicle 1 in anticipation. As shown in FIG. 11, when the driver's seat 140a1 is loaded, for example, after the driver sits back on the driver's seat 140a1, the weighted driver's seat 140a1 moves slightly in the direction of the frame 110, so that the rotation pivot 1522 is displaced downward and relaxed. The cable member 191 further releases the braking effect of the braking device 192 on the wheel body 120.

Furthermore, please refer to FIG. 1 to 2 and please refer to FIG. 12 again. FIG. 12 is a schematic diagram of the first lamp of FIG. In the embodiment, the electric vehicle 1 further includes two first lamps 210 and two second lamps 220. The first luminaire 210 and the second luminaire 220 are electrically connected to the controller 160 and are mounted on the front and rear sides of the frame 110 opposite to each other. Since the first luminaire 210 is similar in structure to the second luminaire 220, FIG. 10 is only illustrated by the first luminaire 210.

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 bulb or an LED lamp. The first light emitting unit 201 and the second light emitting unit 202 are respectively configured to emit light of different colors, so that the first light fixture 210 and the second light fixture 220 can each have a headlight mode and a backlight mode. The so-called headlight mode, for example, the first light-emitting unit 201 of the first light fixture 210 or the second light fixture 220 is turned on, but the second light-emitting unit 202 is turned off. The illumination mode generated when the time is closed; and the backlight mode is, for example, the illumination mode generated when the first illumination unit 201 of the first luminaire 210 or the second luminaire 220 is turned off, but the second illumination unit 202 is turned on. However, the headlight mode and the backlight mode are not limited thereto. For example, in other embodiments, the opening/closing states of the light-emitting units of the lamps in the headlight mode and the backlight mode may be designed according to actual needs, and in each of the lamps. The arrangement of the light units. In addition, the present invention is not limited to the number of the first light emitting unit 201 and the second light emitting unit 202 and their arrangement configuration.

It can be seen that the first lamp 210 and the second lamp 220 adjust the lighting mode according to the direction of the driver's seat 140a1 (ie, the direction in which the driver is currently facing), which helps the bystander to know the state of the current vehicle.

However, it is to be noted that although the electric vehicle of the foregoing embodiment has lamps on both front and rear sides, the present invention is not limited thereto. For example, in other embodiments, the electric vehicle may also have only the first luminaire 210 disposed on one side of the electric vehicle. In this case, the control method of the luminaire can be, for example, referring to FIG. 13B, which is a flowchart of a control method of the first luminaire of the electric vehicle of one embodiment of the present invention.

Beginning at step S31, it is determined whether the first signal switch 181 is triggered. If the first signal switch 181 is triggered, then to step S32, it is determined 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, in step S33, the controller 160 sends an error signal.

If the foregoing step S32 determines that the second signal switch 182 is not triggered, then to step S34, the controller 160 causes the first luminaire 210 to switch to the headlight mode.

If the foregoing step S31 determines that the first signal switch 181 is not triggered, then to step S35, it is determined whether the second signal switch 182 is triggered. If the second signal switch 182 is triggered, then to step S36, the controller 160 causes the first luminaire 210 to switch to the backlight mode.

If the foregoing step S35 determines 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 as described above, or the driver's seat 140a1 is only yet positioned and not triggered correctly. The signal switch goes to step S37, and the controller 160 sends an error signal.

The seat cushion portion 341 is fixed to the frame 310, and the seat back 342 is pivotally connected to the seat cushion portion 341 via the steering mechanism 350, so that the seat back 342 can be swung relative to the seat cushion portion 341 via the steering mechanism 350 to switch the seat 340 toward the first direction. D1 or the 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 be disposed on the lower sides of the steering mechanism 350.

As shown in FIG. 15A, when the seat back 342 is swung relative to the seat cushion portion 341 via the steering mechanism 350 toward the first direction D1, the steering mechanism 350 triggers the first signal switch 181 with respect to one end of the seat back 342; 15B, when the seat back 342 is swung relative to the seat cushion portion 341 via the steering mechanism 350 toward the second direction D2, the second signal switch 182 is triggered by the end of the steering mechanism 350 relative to the seat back 342. Therefore, it can be understood that the embodiment is similar to the manner of operating the vehicle in the foregoing embodiment, so that details are not described herein.

In addition, the electric vehicle of the foregoing embodiment has two signal switches as one of the determining factors for changing the direction of rotation of the output shaft of the driving motor, but the present invention is not limited thereto. For example, in other embodiments, the aforementioned electric vehicle may not have a second signal switch. In this case, referring to FIG. 16 , which is a flowchart of a control method of the electric vehicle according to still another embodiment of the present invention, the controller driving the motor is determined by: step S41, determining whether the first signal switch is trigger. If the first signal switch If it is triggered, then to step S42, it is determined that the forward/reverse gear position sensor receives the forward signal or the backward signal. If it is determined that the forward/reverse gear position sensor receives the forward signal, then to step S43, the controller causes the output shaft of the motor. Rotating in a first direction of rotation to drive the electric vehicle to advance in a first direction that the driver's seat faces. If the foregoing step S42 determines that the forward/reverse gear position sensor receives the back signal, then to step S44, the controller rotates the output shaft of the motor in the second rotation direction to drive the electric vehicle to face the opposite of the driver's seat. The first direction is backward (ie, the electric vehicle is moved in the second direction).

If the foregoing step S41 determines that the first signal switch is not triggered, then to step S45, it is determined that the forward/rear gear position sensor receives the forward signal or the backward signal, and if it is determined that the forward/reverse gear sensor receives the forward signal, Go to step S46, the controller rotates the output shaft of the motor in the second rotation direction to drive the electric vehicle to advance in the second direction facing the driver's seat. If the foregoing step S45 determines that the forward/reverse gear position sensor receives the back signal, then to step S47, the controller rotates the output shaft of the motor in the first rotation direction to drive the electric vehicle to face the opposite of the driver's seat. The second direction is backward (ie, the electric vehicle is moved in the first direction).

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

First, in step S51, it is determined whether the first signal switch is triggered. If so, then to step S52, the controller causes the first luminaire to switch to the headlight mode. If not, then to step S53, the controller causes the first lamp to switch to the backlight mode.

Even in other embodiments, for example, the electric vehicle may not have the aforementioned second signal switch 182 and the gear shifting unit. In this case, referring to FIG. 18, a flow chart of a control method of the electric vehicle according to still another embodiment of the present invention is used to understand the control mode of the controller of the embodiment. In step S61, it is determined whether the first signal switch is triggered. If so, then to step S62, the controller causes the output shaft of the motor to rotate in the first rotational direction; if not, then to step S63, the controller rotates the output shaft of the motor in the second rotational direction. It can be understood that the electric vehicle of the embodiment of FIG. 18 has a control method similar to that of the electric vehicle described in FIG. For the control method of the luminaire, please do not repeat them.

According to the design of the steering mechanism, the operation of the steering mechanism facilitates the operation of the seat during the steering, and the user only needs to get up and rotate the seat to the positioning, thereby solving the problem that the traditional personnel need to use the jack to complete the vehicle. The problem of jacking up and rotating the car body by manpower reduces the labor consumption and the probability of generating safety.

In the operation of the steering process, since the stop portion can limit the range of rotation of the seat relative to the frame, such as only 180 degrees of rotation in a single direction, thereby avoiding the line around or along with the seat The problem that the seat is rotated a lot and is excessively pulled or broken.

Moreover, when the seat faces in 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 that the driver is currently facing according to the state of the signal switch to adaptively adjust the output shaft of the driving motor. Direction, therefore, even if the driver's seat is turned, the driver can continue to operate the electric vehicle in 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 steering after the steering, and can avoid the problem of the work safety caused by the human error in the forward/reverse signal.

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 the result of the component failure and the expected result and the safety problem.

In addition, with the positioning module, the seat can achieve the positioning effect due to the load when the positioning is reached, which helps maintain the state in which the signal switch is triggered.

In addition, the braking mechanism can generate a braking effect on the wheel body when the seat is not loaded, which can avoid the driver's safety problem caused by the driver accidentally sending the forward signal or the backward signal when the seat is turned instead of moving the electric vehicle in anticipation.

Furthermore, switching the lighting mode of the luminaire by changing the trigger condition of the signal switch helps the bystander to know the current driving condition of the electric vehicle.
