Description

Electric vehicle control component, electric vehicle control method, and electric vehicle Technical Field

[0001] The present application relates to the technical field of vehicles for assisted travel, and in particular to an electric vehicle control component, an electric vehicle control method, and an electric vehicle. Background Art

[0002] Electric vehicles can assist users in getting around. However, existing electric vehicles typically use a joystick device mounted on a side armrest, which the user turns by toggling. This single-handed, side-controlled steering method is not compatible with the driving habits of most users. It is difficult to accurately determine the desired direction using the joystick device, resulting in a driving route that does not meet the user's expectations and a reduced user experience.

[0003] Summary of the Invention

[0004] In view of this, the purpose of this application is to propose an electric vehicle control component, an electric vehicle control method and an electric vehicle, so as to solve the problem that the steering method using one hand and side control does not conform to the driving habits of the general public.

[0005] Based on the above-mentioned purpose, the first aspect of the present application provides an electric vehicle control component, which is applied to an electric vehicle including a carrying mechanism, wherein the carrying mechanism is used to carry a user, and the electric vehicle control component includes: a connecting mechanism, connected to the carrying mechanism; a steering mechanism, connected to the connecting mechanism, and the steering mechanism is used to control the steering of the electric vehicle; wherein the connecting mechanism has a first state in which the steering mechanism is located in front of the user.

[0006] Based on the same inventive concept, the second aspect of the present application also provides an electric vehicle control component, which is applied to an electric vehicle, including: a steering mechanism for controlling the steering of the electric vehicle; an angle sensor, matched with the steering mechanism, for detecting the rotation angle of the steering mechanism to generate an electrical signal identifying the rotation angle; a direction mechanism, for generating a direction signal based on a user's trigger operation; a control module, connected to the angle sensor and the direction mechanism, for generating a heading angle signal based on the electrical signal; and generating a drive signal based on the direction signal and the heading angle signal to drive the electric vehicle to move.

[0007] Based on the same inventive concept, the third aspect of this application also provides an electric vehicle control method, including: obtaining the direction signal and heading angle signal of the electric vehicle; generating a driving signal based on the direction signal and the heading angle signal; and driving the electric vehicle to move based on the driving signal.

[0008] Based on the same inventive concept, the fourth aspect of the present application also provides an electric vehicle, comprising the electric vehicle control component as described in the first aspect or the second aspect.

[0009] As can be seen from the above, the electric vehicle control assembly and electric vehicle provided by this application can, when the connection mechanism is in the first state, the steering mechanism can be located in the middle position in front of the user. Compared with the direction control of traditional electric vehicles through the remote control device set on the armrest, this is more in line with conventional usage habits, allowing users to accurately control the rotation angle of the electric vehicle to be consistent with the desired rotation angle, thereby improving the user experience. In addition, there is no need to set the steering mechanism according to the user's operating habits, which reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0023] It should be noted that the relative arrangement of the components, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise.

[0024] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0025] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0026] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] As shown in FIG2 , the electric vehicle 1000 may include an electric wheelchair or a mobility scooter, etc. In an electric wheelchair, a rocker device is usually provided on one side armrest of the electric wheelchair, and a user controls the electric wheelchair by toggling a rocker in the rocker device.

[0028] However, the applicant discovered that, on the one hand, controlling the electric vehicle 1000 with a joystick controlled by one hand does not conform to the conventional driving experience; on the other hand, it is difficult for the user to accurately control the steering with the joystick, resulting in a driving route that does not meet the user's expectations and reducing the user's experience. In addition, the joystick is often located on the left or right hand side of the electric vehicle 1000, and users have different left-handed or right-handed operating habits. This requires the installation of the joystick to adapt to the user's operating habits. The joystick installation of the electric vehicle 1000 may be different for different users, resulting in increased production costs.

[0029] In view of this, as shown in Figures 1 and 2, an embodiment of the present application provides an electric vehicle control component, which is applied to an electric vehicle 1000 including a carrying mechanism 200, the carrying mechanism 200 is used to carry a user, and the electric vehicle control component includes: a connecting mechanism 110, connected to the carrying mechanism 200; a steering mechanism 500, connected to the connecting mechanism 110, the steering mechanism 500 is used to control the steering of the electric vehicle 1000; wherein, the connecting mechanism 110 has a first state in which the steering mechanism 500 is located in front of the user.

[0030] When the user is located on the carrying mechanism 200 , the connecting mechanism 110 may be in the first state, and the steering mechanism 500 connected to the connecting mechanism 110 is located in the middle position in front of the user.

[0031] For example, the steering mechanism 500 may be located directly in front of the user.

[0032] The user can operate the steering mechanism 500 located in front of the electric vehicle 1000 to steer. Compared to conventional electric vehicles that use a joystick device on the armrest to control the direction, this is more in line with common usage habits, allowing the user to accurately control the rotation angle of the electric vehicle to match the desired rotation angle, thereby improving the user experience. In addition, there is no need to configure the steering mechanism 500 and the steering mechanism according to the user's operating habits, which reduces costs.

[0033] It should be understood that the front of the user may refer to a direction in front of the user, and is not limited to the front of the user, as long as it is not the left or right of the user.

[0034] As shown in Figure 3, in some embodiments, the connecting mechanism 110 includes a first end 1103 that is detachably connected to the supporting mechanism 200; wherein, when the connecting mechanism 110 is in a first state, the first end 1103 is connected to the supporting mechanism 200; the connecting mechanism 110 also has a second state in which the first end 1103 is away from the supporting mechanism 200.

[0035] Exemplarily, when the connecting mechanism 110 is in the first state, the first end 1103 thereof may be located on one side of the supporting mechanism 200 .

[0036] When the user is on the supporting structure 200 or outside the electric vehicle 1000, the connecting mechanism 110 can be in the first state. When the user needs to leave the supporting structure 200 or enter the electric vehicle 1000, the connecting mechanism 110 can be switched to the second state and maintained there. In this state, since the first end 1103 of the connecting mechanism 110 is away from the supporting structure 200, a passage for the user's movement is formed between the first end 1103 and the supporting structure 200, without hindering the user's movement.

[0037] As shown in FIG. 3 , in some embodiments, the connecting mechanism 110 includes a second end 1102 away from the first end 1103 , and the second end 1102 is rotatably connected or detachably connected to the supporting mechanism 200 .

[0038] The manner in which the second end 1102 is detachably connected to the supporting mechanism 200 and the manner in which the first end 1103 is detachably connected to the supporting mechanism 200 may be the same, and will not be described in detail herein.

[0039] For example, the supporting mechanism 200 may be provided with a shaft sleeve structure or a shaft hole structure, and the second end 1102 may be provided with a shaft structure that can be passed through the shaft sleeve structure or the shaft hole structure; or, the connecting mechanism 110 may be provided with a shaft sleeve structure or a shaft hole structure, and the supporting mechanism 200 may be provided with a shaft structure that can be passed through the shaft sleeve structure or the shaft hole structure.

[0040] For example, the second end 1102 can be rotatably connected to one side of the supporting mechanism 200 , and the connecting mechanism 110 can be laterally rotated around the end or can be flipped longitudinally around the end.

[0041] When the connection mechanism 110 is in the first state, the second end 1102 and the first end 1103 of the connection mechanism 110 are respectively located on both sides of the supporting mechanism 200 , and the connection mechanism 110 as a whole may be a fence-like structure in front of the user.

[0042] When the connecting mechanism 100 switches from the first state to the second state, the connecting mechanism 110 can be driven (for example, manually or by triggering a driving mechanism such as a motor or a telescopic cylinder) to rotate about the second end 1102. At this time, since the first end 1103 of the connecting mechanism 110 is away from the supporting mechanism 200, that is, the connecting mechanism 110 is entirely located on one side of the supporting mechanism 200 (the side where the supporting mechanism 200 is rotatably connected to the second end 1102 of the connecting mechanism 110), a passage for users to move can be formed in front of the supporting mechanism 200.

[0043] As shown in FIG. 3 , in some embodiments, the electric vehicle control assembly includes a first connection base 120 disposed on one side of the supporting mechanism 200 , and the second end 1102 is rotatably connected to the first connection base 120 .

[0044] For example, the first connecting seat 120 and the supporting mechanism 200 may be fixedly connected or detachably connected.

[0045] For example, the first connecting seat 120 and the supporting mechanism 200 can be connected by plugging, snapping, gluing, welding or fastener connection.

[0046] Exemplarily, the rear end of the first connecting seat 120 (along the travel direction of the electric vehicle) is connected to the supporting mechanism 200 , and the front end is rotatably connected to the second end 1102 of the connecting mechanism 110 .

[0047] In this embodiment, on the one hand, the first connecting seat 120 can be designed to be structurally adaptable with the supporting mechanism 200, and on the other hand, the first connecting seat 120 can provide a rotational connection basis for the connecting mechanism 110. Therefore, the structural design of the connecting mechanism 110 does not need to be limited by the structure of the supporting mechanism 200 of the electric vehicle 1000, making the structural design of the connecting mechanism 110 more flexible.

[0048] As shown in Figure 3, in some embodiments, the first connecting seat 120 is provided with a rotating connecting hole 1201; the second end 1102 is provided with a rotating shaft 1104, and the rotating shaft 1104 is passed through the rotating connecting hole 1201 so that the connecting mechanism 110 can rotate around the axis of the rotating connecting hole 1201.

[0049] For example, the axis of the rotating connection hole 1201 is horizontal; the connection mechanism 110 can be rotated longitudinally around the axis of the rotating connection hole 1201, and its rotation direction is shown by the arrow in Figure 2. Compared with horizontal rotation, longitudinal rotation of the connection mechanism 110 saves more space and avoids the problem that the connection mechanism 110 cannot be rotated into place due to insufficient space in front of the electric vehicle 1000, which would hinder the user from getting on and off the electric vehicle 1000.

[0050] The structure with the rotating connection hole 1201 needs to have relatively large dimensions. However, the first connection base 120 is disposed on one side of the supporting mechanism 200. Even if its dimensions are relatively large, it will not hinder the user from entering or exiting the front of the electric vehicle 1000. Therefore, in this embodiment, the rotating connection hole 1201 is disposed on the first connection base 120. At the same time, because the first connection base 120 needs to bear the entire weight of the connecting mechanism 110 when the connecting mechanism 110 is switched to the second state, in order to ensure greater strength, it also needs to have a certain material thickness and relatively large dimensions.

[0051] If the connecting mechanism 110 is too large, it will occupy the space in front of the electric vehicle 1000 when in the second state, thereby hindering the user from getting on and off the electric vehicle 1000. Therefore, in this embodiment, a relatively small rotating shaft 1104 is disposed at the second end 1102 of the connecting mechanism 110, so that the external dimensions of the connecting mechanism 110 are not limited by the rotational connection structure between the connecting mechanism 110 and the supporting mechanism 200.

[0052] As shown in FIG. 3 , in some embodiments, an annular groove 1105 is provided on the peripheral wall of the rotating shaft 1104 , and a limiting structure extending into the annular groove 1105 is provided in the rotating connection hole 1201 .

[0053] For example, the cross-sectional shape of the rotating shaft 1104 may be circular or polygonal.

[0054] Illustratively, the annular groove 1105 is close to the end of the rotating shaft 1104 .

[0055] The annular groove 1105 includes two groove walls spaced apart along the axis of the rotating shaft 1104, and the limiting structure is located between the two groove walls. The groove walls and the limiting structure cooperate with each other to limit the movement of the rotating shaft 1104 along its axial direction, thereby preventing the connecting mechanism 110 from separating from the first connecting seat 120 during rotation.

[0056] As shown in Figure 4, in some embodiments, the first connecting seat 120 is provided with a pin hole 1202 connected to the rotating connecting hole 1201, and the electric vehicle control assembly also includes a limit card 130 connected to the first connecting seat 120 through the pin hole 1202, and the limit card 130 extends into the annular groove 1105 when inserted into the pin hole 1202.

[0057] Exemplarily, the latch hole 1202 is disposed at the bottom of the first connecting seat 120 and is arranged along the radial direction of the rotating connecting hole 1201 .

[0058] Exemplarily, the limiting clamp 130 is a plate-shaped structure.

[0059] For example, the limiting clamp 130 can be positioned in the pin hole 1202 of the first connecting seat 120 by means of adhesive connection, clamping or welding.

[0060] Exemplarily, the end of the limiting clamp 130 facing the rotating connection hole 1201 is concave arc-shaped, and the size of the concave arc corresponds to the size of the bottom of the annular groove 1105.

[0061] During assembly, first insert the rotating shaft 1104 of the connecting mechanism 110 into the rotating connection hole 1201 of the first connecting base 120, and align the annular groove 1105 on the rotating shaft 1104 with the latch hole 1202 of the first connecting base 120. Then, insert the limiting clamp 130 into the latch hole 1202 until its end, acting as a limiting structure, extends into the annular groove 1105 to limit the position of the connecting shaft.

[0062] As shown in Figure 4, in some embodiments, the electric vehicle control assembly includes a second connecting seat 140, which is arranged on a side of the supporting mechanism 200 away from the first connecting seat 120; the second connecting seat 140 is provided with a limiting portion 1401, which abuts against the limiting portion 1401 when the connecting mechanism 110 is in the first state; and is separated from the limiting portion 1401 when the connecting mechanism 110 is in the second state.

[0063] Illustratively, the connection method between the second connecting base 140 and the supporting mechanism 200 is the same as the connection method between the first connecting base 120 and the supporting mechanism 200, and will not be described in detail here.

[0064] Illustratively, the limiting portion 1401 is a block structure.

[0065] When the connecting mechanism 110 is in the first state, its second end 1102 is supported by the first connecting seat 120, and the first end 1103 is in contact with the limiting portion 1401 of the second connecting seat 140, that is, the limiting portion 1401 supports the first end 1103 of the connecting mechanism 110 to ensure that the connecting mechanism 110 in the first state can be stably located in front of the user.

[0066] As shown in Figures 3 and 4, in some embodiments, a limiting groove 1106 is provided at the bottom of the connecting mechanism 110 and extends through the first end 1103. When the connecting mechanism 110 is in the first state, the connecting mechanism 110 is plugged into and abutted against the limiting portion 1401 of the second connecting seat 140 through the limiting groove 1106.

[0067] Exemplarily, the limiting portion 1401 is located at the end of the second connecting seat 140 away from the supporting mechanism 200 .

[0068] When the connecting mechanism 110 switches from the second state to the first state through longitudinal rotation, the connecting mechanism 110 gradually approaches the second connecting base 140 from top to bottom until the limiting portion 1401 on the second connecting base 140 is inserted into the limiting groove 1106 of the first end 1103 of the connecting mechanism 110 and abuts against the bottom of the limiting groove 1106, and the connecting mechanism 110 stops rotating. At this time, the limiting portion 1401 supports the first end 1103 of the connecting mechanism 110, and the connecting mechanism 110 can remain in the first state.

[0069] As shown in Figures 3 and 4, in some embodiments, the limiting portion 1401 is provided with a limiting longitudinal groove 1402 running through the top and the bottom, and the connecting mechanism 110 is provided with a limiting plate 1107 at the notch of the limiting groove 1106 near the first end 1103. When the connecting mechanism 110 is in the first state, the limiting plate 1107 is plugged into the limiting portion 1401 through the limiting longitudinal groove 1402.

[0070] Exemplarily, the limiting portion 1401 includes a root portion 14011 fixedly connected to other parts of the second connecting seat 140 and an end portion 14012 away from the root portion. The limiting longitudinal groove 1402 is provided at the root portion 14011 of the limiting portion 1401 .

[0071] Exemplarily, the limiting longitudinal groove 1402 is symmetrically arranged relative to the axis of the limiting portion 1401 .

[0072] The limiting longitudinal groove 1402 is provided with two groove walls spaced apart along the axis of the limiting portion 1401. When the connecting mechanism 110 gradually approaches the second connecting seat 140 from top to bottom, while the limiting portion 1401 is inserted into the limiting groove 1106, the limiting plate 1107 is inserted between the two groove walls of the limiting longitudinal groove 1402, thereby realizing the positioning of the connecting mechanism 110 and preventing the first end 1103 of the connecting mechanism 110 from moving along the axial direction of the limiting portion 1401.

[0073] As shown in FIG1 , in some embodiments, the electric vehicle control assembly further includes a direction mechanism 700 , which is used to control the electric vehicle to move forward or backward. Specifically, the direction mechanism 700 may generate a direction signal based on a user's triggering operation.

[0074] For example, the steering mechanism 700 may include a linear trigger device, such as a button, a finger-operated throttle, a pressure sensor, etc.

[0075] The direction mechanism 700 can generate a direction signal based on a trigger operation by the user, and the electric vehicle 1000 can move forward or backward according to the direction signal.

[0076] In some embodiments, the steering mechanism 500 includes a joystick mechanism, a handlebar mechanism, or a steering wheel mechanism.

[0077] For example, the direction mechanism 700 may be provided on the steering mechanism 500 , as shown in FIG. 1 .

[0078] For example, the direction mechanism 700 and the steering mechanism 500 may be provided on the same object, for example, the direction mechanism 700 and the steering mechanism 500 may be provided on the same handle.

[0079] For example, the steering mechanism 700 and the steering mechanism 500 can be set on different objects. For example, the steering mechanism 500 is set in the hand operation area and the steering mechanism 700 is set in the user's foot pedal area, so that the user can operate the steering mechanism 500 with his hands and trigger the steering mechanism 700 with his feet.

[0080] In some embodiments, when the steering mechanism 700 is triggered in a first manner, a direction signal (hereinafter referred to as the forward signal) is generated to control the electric vehicle 1000 to move forward; when the steering mechanism 700 is triggered in a second manner, a direction signal (hereinafter referred to as the backward signal) is generated to control the electric vehicle 1000 to move backward.

[0081] In some embodiments, the direction mechanism 700 includes a lever, wherein the first mode includes moving the lever in a first direction, and the second mode includes moving the lever in a second direction, the first direction being different from the second direction;

[0082] Alternatively, the steering mechanism 700 includes a throttle, wherein the first mode includes rotating the throttle in a third direction, and the second mode includes rotating the throttle in a fourth direction, the third direction being opposite to the fourth direction.

[0083] The direction mechanism 700 may be a single operating mechanism, and the user changes the state of the direction mechanism 700 through different trigger operations, thereby generating different signals. The first direction and the second direction may refer to opposite directions, such as up and down, left and right. The third direction and the fourth direction may refer to opposite directions, such as front and back. Specifically, the direction mechanism 700 may be a lever, and the user may move the lever to the left to generate a forward signal; the user may move the lever to the right to generate a backward signal; or the user may move the lever to the right to generate a forward signal; the user may move the lever to the left to generate a backward signal. For example, the direction mechanism 700 may be a throttle, and the user may turn the throttle forward to generate a forward signal; the user may turn the throttle backward to generate a backward signal.

[0084] In addition, the direction mechanism 700 may also be a plurality of operating mechanisms, and the user generates different signals by triggering different operating mechanisms.

[0085] As shown in Figure 3, in some embodiments, the steering mechanism 700 includes a first steering mechanism 710 and a second steering mechanism 720, the first steering mechanism 710 includes one of a finger-operated throttle, a handlebar throttle, or a pressure sensor, and the second steering mechanism 720 is of the same type as the first steering mechanism 710; wherein the first steering mechanism 710 and the second steering mechanism 720 are arranged on the same side, on both sides, or in the middle of the steering mechanism 500.

[0086] For example, the first steering mechanism 710 and the second steering mechanism 720 are symmetrically arranged on the steering mechanism 500. Specifically, as shown in FIG3 , an axis-like structure can be provided in the middle of the steering mechanism 500 so that the steering mechanism 500 can be rotatably arranged on the connecting mechanism 110. With the middle of the steering mechanism 500 as the center, the first steering mechanism 710 and the second steering mechanism 720 are symmetrically arranged. This allows users to conveniently and quickly operate the steering mechanism 500 and the steering mechanism 700, allowing users to accurately adjust the steering angle of the electric vehicle, thereby improving the user experience.

[0087] For example, the first direction mechanism 710 and the second direction mechanism 720 may both be finger-type throttles. As shown in FIG3 , the first direction mechanism 710 may be a forward finger-type throttle. When the user triggers the forward finger-type throttle, a forward signal is generated. The second direction mechanism 720 may be a reverse finger-type throttle. When the user triggers the reverse finger-type throttle, a reverse signal is generated. For another example, the first direction mechanism 710 and the second direction mechanism 720 may both be handlebar throttles. When the user turns one handlebar throttle, a forward signal is generated; when the user turns the other handlebar throttle, a reverse signal is generated. For another example, the first direction mechanism 710 and the second direction mechanism 720 may both be pressure sensors. When the user triggers one pressure sensor, a forward signal is generated; when the user triggers the other pressure sensor, a reverse signal is generated.

[0088] As shown in Figures 5, 6 and 7, in some embodiments, the steering mechanism 500 includes: a steering mechanism body 510, which is provided with a steering longitudinal axis 520; a supporting platform 1101 is provided in the middle of the connecting mechanism 110, and a steering through hole 1108 is provided on the top of the supporting platform 1101, which passes through the bottom of the connecting mechanism 110, and the steering longitudinal axis 520 is passed through the steering through hole 1108 to enable the steering mechanism body 510 to be rotatably connected to the connecting mechanism 110; a follower mechanism 530, which is connected to the end of the steering longitudinal axis 520 passing through the steering through hole 1108, and the follower mechanism 530 rotates with the steering mechanism body 510.

[0089] For example, in addition to the steering mechanism 500 and the steering mechanism 700, the electric vehicle control assembly may further include an angle sensor (not shown) configured to match the steering mechanism 500 (e.g., disposed within the steering mechanism 500) and configured to detect the rotation angle of the steering mechanism 500 and generate an electrical signal indicating the rotation angle, such as a current signal or a voltage signal indicating the rotation angle. For example, the angle sensor may include a contactless Hall effect device.

[0090] In an embodiment of the present disclosure, the electric vehicle 1000 can achieve steering according to the electrical signal indicating the rotation angle.

[0091] In order to enable the electric vehicle 1000 to turn according to the electrical signal indicating the rotation angle, the electric vehicle control assembly may further include: a control module (not shown) connected to the angle sensor and the steering mechanism 700, configured to generate a heading angle signal based on the electrical signal indicating the rotation angle; and to generate a driving signal based on the heading angle signal and the heading angle signal generated by the steering mechanism 700 to drive the electric vehicle 1000 to move.

[0092] In some embodiments, the control module may include a processor (e.g., a microcontroller unit (MCU)). The control module may convert the electrical signal indicating the rotation angle output by the angle sensor into a heading angle signal, thereby generating a drive signal. The drive signal may include forward or reverse rotation of the drive wheel, a first rotational speed of the left drive wheel, and a second rotational speed of the right drive wheel. The control module transmits the drive signal to the drive device.

[0093] For example, the steering mechanism body 510 may be a steering wheel or a bar handle.

[0094] For example, the cross-sectional shape of the end portion of the steering longitudinal shaft 520 passing through the steering through-hole 1108 is polygonal, and the top portion of the follower mechanism 530 is provided with a groove 531 that matches the polygonal end portion 521 of the steering longitudinal shaft 520, as shown in FIG3 . The polygonal end portion 521 of the steering longitudinal shaft 520 is inserted into the groove 531, as shown in FIG5 , to enable the follower mechanism 530 to rotate along with the steering mechanism body 510.

[0095] Exemplarily, the end of the steering longitudinal axis 520 passing through the steering through hole 1108 can be provided with at least two protrusions, and the top of the follower mechanism 530 can be provided with grooves corresponding to the protrusions one by one, and the protrusions are inserted into the grooves to enable the follower mechanism 530 to rotate with the steering mechanism body 510.

[0096] Exemplarily, the steering mechanism body 510 and the follower mechanism 530 are connected by fasteners such as bolts.

[0097] The user can drive the electric vehicle 1000 to change its moving direction by rotating the steering mechanism 500. The rotation direction of the steering mechanism 500 is the same as the changing direction of the moving direction of the electric vehicle 1000, and the rotation angle of the steering mechanism 500 corresponds to the changing angle of the moving direction of the electric vehicle 1000.

[0098] As shown in Figures 3 and 5, in some embodiments, the steering mechanism 500 includes a reset elastic member 540, which is arranged between the steering mechanism body 510 and the connecting mechanism 110; or, the reset elastic member 540 is arranged between the follower mechanism 530 and the connecting mechanism 110.

[0099] Exemplarily, the reset elastic member 540 may be a reset torsion spring.

[0100] When the steering mechanism 500 rotates under the external force of the user, the reset elastic member 540 can generate elastic force. When the external force no longer acts on the steering mechanism 500, the steering mechanism 500 will rotate back to the initial position under the elastic force of the reset elastic member 540.

[0138] Communication mechanism, used to realize communication with external devices.

[0139] Among them, the user can interact with the electric vehicle through the interactive mechanism. Specifically, the user can control the operation of the electric vehicle by controlling the trigger mechanism. For example, the control trigger mechanism can be a control button for controlling the state switching, power on or off, speed switching, etc. of the electric vehicle. The electric vehicle can also display the real-time operating parameters of the electric vehicle through a display mechanism. For example, the display mechanism can be a display screen, and the display screen can display one or more of the residual current, real-time speed or current speed gear. Prompt information, such as abnormal alarm information, can also be output through a sound mechanism (such as a voice speaker). The interactive mechanism can be integrated into a device and can be distributed on the electric vehicle. The interactive mechanism can be arranged together with the steering mechanism. For example, both are arranged on the steering wheel or handle; the interactive mechanism and the steering mechanism can also be arranged separately, which is suitable for the user to watch and operate.

[0140] Based on the same inventive concept and in combination with the description of the electric vehicle 1000 in each of the above embodiments, this embodiment provides a method for controlling an electric vehicle.

[0141] FIG10 shows a control method for an electric vehicle according to an embodiment of the present disclosure. As shown in FIG10 , the control method for an electric vehicle may include:

[0142] Step S910: Acquire the direction signal and heading angle signal of the electric vehicle.

[0143] In some embodiments, acquiring the direction signal and the heading angle signal further includes:

[0144] In response to the direction mechanism of the electric vehicle being triggered, obtaining a direction signal; the direction signal includes a forward signal or a reverse signal; and,

[0145] In response to a steering mechanism of the electric vehicle being triggered, obtaining an identification rotation angle from an angle sensor matched with the steering mechanism;

[0146] Convert the electrical signal into a heading angle signal.

[0147] As shown in FIG8 and as described above, the electric vehicle control assembly may further include a control module (not shown), which is connected to the angle sensor and the direction mechanism 700, and is used to generate a heading angle signal based on the above-mentioned electrical signal, and to generate a drive signal based on the direction signal and the heading angle signal to drive the electric vehicle 1000 to move. For example, the control module may include a processor (such as an MCU, a micro control unit). The above-mentioned control module may also be arranged inside the above-mentioned rotating mechanism 500. The drive signal may include forward or reverse rotation of the drive wheel, a first speed of the left drive wheel, and a second speed of the right drive wheel, and the control module sends the drive signal to the drive mechanism.

[0148] Exemplarily, the electric vehicle 1000 may further include a drive mechanism (not shown) electrically connected to the control module and the drive wheel 400, for controlling the rotation of the drive wheel 400 based on the drive signal generated by the control module; and a drive actuator (not shown) connected to the drive mechanism, for driving the rotation of the drive wheel 400 based on the driving force of the drive mechanism to move the electric vehicle 1000. The above-mentioned drive mechanism and drive actuator may also be provided on the rear support frame. Specifically, the drive wheel 400 may be electrically connected to the drive mechanism, and the drive mechanism controls the rotation of the drive wheel 400 based on the drive signal. When the drive mechanism controls the drive wheel 400 to rotate in a first direction (e.g., forward or reverse), the drive wheel 400 can drive the electric vehicle 1000 forward; when the drive mechanism controls the drive wheel 400 to rotate in a second direction (e.g., reverse or forward), the drive wheel 400 can drive the electric vehicle 1000 backward, wherein the second direction is opposite to the first direction. It should be understood that the electric vehicle may include two wheels, in which case the two wheels may be driving wheels; the electric vehicle may also include three wheels or more wheels, which is not limited here.

[0149] Specifically, the user can operate the steering mechanism 500 and trigger the direction mechanism 700. The angle sensor detects the rotation angle of the steering mechanism 500 and outputs a corresponding voltage signal, and the direction mechanism 700 issues a forward signal or a reverse signal. The control component converts the voltage signal output by the angle sensor into a heading angle signal.

[0150] For example, the driving mechanism may include a motor. Specifically, the motor drives the left driving wheel to rotate at a first speed and the right driving wheel to rotate at a second speed based on a driving signal to control the electric vehicle to move according to the steering angle desired by the user.

[0151] In some embodiments, the drive mechanism includes dual drive motors, and the drive actuator includes a differential chassis; or, the drive mechanism includes a single drive motor, and the drive actuator includes an electronically controlled Ackerman steering chassis; or, the drive mechanism includes four drive motors, and the drive actuator includes a four-wheel independent drive chassis.

[0152] Specifically, for a dual rear-drive motor differential chassis, heading control and forward and reverse control can be achieved through the differential speed of the dual rear-wheel motors. For a single-motor drive, electronically controlled Ackerman steering chassis, steering control is achieved by electrically controlling the front-wheel Ackerman steering through the steering mechanism, and the dual rear wheels respond to turns and control forward and backward movement through a single motor combined with a mechanical differential. For a chassis with four independently driven Mecanum wheels, turning, forward and reverse movement can be achieved through four-wheel steering control. It should be understood that the above-mentioned drive mechanisms and drive actuators are merely examples and are not intended to be limiting. The drive actuators may also include other four-wheel or three-wheel motion chassis capable of steering, forward and reverse movement.

[0153] In step S920 , a driving signal is generated based on the direction signal and the heading angle signal.

[0154] In step S930 , the electric vehicle is driven to move based on the driving signal.

[0155] Specifically, when a user rides an electric vehicle, he or she can control the steering mechanism with one hand or both hands. When the steering mechanism is turned, the angle sensor detects the rotation angle α of the steering mechanism, and the angle sensor outputs a corresponding current signal or voltage signal. The user can also trigger the steering mechanism with his or her hands, such as by turning the throttle with his or her hands, by turning the lever with his or her hands, by triggering the pressure sensor with his or her hands, by turning the throttle forward (e.g., clockwise) or backward (e.g., counterclockwise) with his or her hands, or by controlling the foot throttle with his or her feet, etc., to generate a corresponding forward signal or reverse signal. The control module converts the current signal or voltage signal into a heading angle signal about the rotation angle α, and combines the forward signal or reverse signal with the heading angle signal to convert it into a drive signal. The control module sends the drive signal to the drive mechanism, and the motor and differential in the drive mechanism control the drive wheel based on the drive signal, and the drive actuator cooperates with the drive mechanism to execute the forward or reverse steering of the electric vehicle at the rotation angle of the steering mechanism turned by the user.

[0156] It can be seen that compared to the electric vehicles in the related art, the electric vehicle of the embodiment of the present disclosure uses electrical signals to control the movement of the electric vehicle, eliminating the mechanical transmission mechanism between the steering mechanism and the front wheels in the electric vehicles in the related art, and reducing the volume of the vehicle body. In addition, the user steers through the steering mechanism set in front of the user (especially located directly in front of the user, for example, when the user operates the steering mechanism, the steering mechanism is in the middle position in front of the user). Compared with the electric vehicles in the related art that use a remote control device set on the armrest to control the direction, it is more in line with conventional usage habits, allowing the user to accurately control the rotation angle of the electric vehicle to be consistent with the desired rotation angle, thereby improving the user experience.
