Detailed Description

The present application will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present application more apparent.

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

Meanwhile, it should be understood that the sizes of the respective parts shown in the drawings are not drawn in actual scale for convenience of description.

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

It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present application belongs. The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

As shown in fig. 2, the electric vehicle 1000 may include an electric wheelchair, a scooter, or the like. The rocker device is arranged on one side armrest of the electric wheelchair, and a user controls the electric wheelchair to run by pulling a remote rod in the remote rod device.

However, applicants have found that on the one hand, controlling the travel of electric vehicle 1000 by controlling the joystick with one hand does not meet the conventional driving experience; on the other hand, the user is difficult to accurately control steering through the remote rod, so that the driving route does not meet the expectations of the user, and the use experience of the user is reduced. In addition, the remote rod is often disposed on the left hand side or the right hand side of the electric vehicle 1000, and the operation habits of the user on the left hand side or the right hand side are different, so that the installation of the remote rod needs to adapt to the operation habits of the user, and the installation of the remote rod of the electric vehicle 1000 of different users may be different, resulting in an increase of the production cost.

In view of this, as shown in fig. 1 and 2, an embodiment of the present application provides an electric vehicle control assembly applied to an electric vehicle 1000 including a carrying mechanism 200, the carrying mechanism 200 is used for carrying a user, and the electric vehicle control assembly includes: a connection mechanism 110 connected to the carrying mechanism 200; the steering mechanism 500 is connected to the connecting mechanism 110, and the steering mechanism 500 is used for controlling the steering of the electric carrier 1000; wherein the connection mechanism 110 has a first state in which the steering mechanism 500 is positioned in front of the user.

When the user is located on the carrying mechanism 200, the connection mechanism 110 may be in the first state, and the steering mechanism 500 connected to the connection mechanism 110 is located at a front middle position of the user.

Illustratively, the steering mechanism 500 may be located directly in front of the user.

The user can operate through the steering mechanism 500 that is located its place ahead to order about electric carrier 1000 to turn to, compare in traditional electric carrier and carry out directional control through the remote lever device that sets up on the handrail, more accord with conventional use habit, make the rotation angle that the user can accurately control electric carrier unanimous with expected rotation angle, improved user experience. In addition, the steering mechanism 500 and the direction mechanism do not need to be arranged according to the operation habit of the user, so that the cost is reduced.

It should be appreciated that the user's front may refer to a direction in front of the user and is not limited to just in front of the user, as long as it is not just to the right of the user's left Fang Huozheng.

As shown in fig. 3, in some embodiments, the connection mechanism 110 includes a first end 1103 that is removably connected to the carrier mechanism 200; when the connection mechanism 110 is in the first state, the first end 1103 is connected to the carrying mechanism 200; the connection mechanism 110 also has a second state in which the first end 1103 is away from the carrier 200.

For example, when the connection mechanism 110 is in the first state, the first end 1103 thereof may be located at one side of the carrying mechanism 200.

The connection mechanism 110 may be in the first state when a user is located on the carrying mechanism 200 or outside the electric vehicle 1000. When the user needs to leave the carrying mechanism 200 or enter the electric vehicle 1000, the connection mechanism 110 may be switched to the second state and maintained. At this time, since the first end 1103 of the connection mechanism 110 is far away from the carrying mechanism 200, a channel for the user to move can be formed between the first end 1103 and the carrying mechanism 200, and no blocking is caused to the movement of the user.

As shown in fig. 3, in some embodiments, the connection mechanism 110 includes a second end 1102 remote from the first end 1103, the second end 1102 being rotatably or removably coupled to the carrier mechanism 200.

The manner in which the second end 1102 is detachably connected to the carrying mechanism 200 may be the same as the manner in which the first end 1103 is detachably connected to the carrying mechanism 200, which is not described herein.

Illustratively, the bearing mechanism 200 may be provided with a sleeve structure or a shaft hole structure, and the second end 1102 may be provided with a shaft structure capable of being inserted into the sleeve structure or the shaft hole structure; alternatively, the connection mechanism 110 may be provided with a sleeve structure or a shaft hole structure, and the bearing mechanism 200 may be provided with a shaft structure capable of being inserted into the sleeve structure or the shaft hole structure.

Illustratively, the second end 1102 may be rotatably coupled to one side of the carrier 200 and the coupling mechanism 110 may be rotatable laterally about the end or may be reversible longitudinally about the end.

When the connection mechanism 110 may be in the first state, the second end 1102 and the first end 1103 of the connection mechanism 110 may be located at two sides of the carrying mechanism 200, and the connection mechanism 110 may be in a fence structure in front of the user.

The connection mechanism 110 may be actuated (e.g., manually actuated or actuated by a drive mechanism such as a trigger motor, telescoping cylinder, etc.) to rotate about the second end 1102 as the connection mechanism 100 is switched from the first state to the second state. At this time, since the first end 1103 of the connection mechanism 110 is far away from the carrying mechanism 200, that is, the connection mechanism 110 is integrally located on one side of the carrying mechanism 200 (the side is the side where the carrying mechanism 200 is rotatably connected to the second end 1102 of the connection mechanism 110), the front of the carrying mechanism 200 can form a channel for the user to move.

As shown in fig. 3, in some embodiments, the electric vehicle control assembly includes a first connecting seat 120 disposed on one side of the carrying mechanism 200, and a second end 1102 is rotatably connected to the first connecting seat 120.

For example, the first connection base 120 and the carrying mechanism 200 may be fixedly connected or detachably connected.

The first connection base 120 and the carrying mechanism 200 may be connected by plugging, clamping, adhesive connection, welding or fastening.

Illustratively, the rear end (along the traveling direction of the electric vehicle) of the first connecting seat 120 is connected to the carrying mechanism 200, and the front end is rotatably connected to the second end 1102 of the connecting mechanism 110.

In the present embodiment, the first connecting seat 120 can be designed with structural adaptability to the carrying mechanism 200, and the first connecting seat 120 can provide a rotational connection foundation for the connecting mechanism 110, so that the structural design of the connecting mechanism 110 is not limited to the structure of the carrying mechanism 200 of the electric vehicle 1000, and the structural design of the connecting mechanism 110 is more flexible.

As shown in fig. 3, in some embodiments, the first coupling seat 120 is provided with a rotational coupling hole 1201; the second end 1102 is provided with a rotation shaft 1104, and the rotation shaft 1104 is provided to pass through the rotation connection hole 1201 so that the connection mechanism 110 can rotate about the axis of the rotation connection hole 1201.

Illustratively, the axis direction of the rotational coupling hole 1201 is a horizontal direction; the connection mechanism 110 is capable of being turned longitudinally about the axis of the rotational connection hole 1201 in the direction of the arrow shown in fig. 2. Compared with the transverse rotation mode, the connecting mechanism 110 can be longitudinally overturned to save space, and the problem that the connecting mechanism 110 cannot rotate in place due to insufficient space in front of the electric carrier 1000, so that the electric carrier 1000 is blocked for users to go up and down is avoided.

The structure of the rotary connecting hole 1201 needs to have a larger external dimension, and the first connecting seat 120 is disposed on one side of the carrying mechanism 200, and even if the external dimension is larger, the external dimension will not prevent the user from entering and exiting from the front of the electric vehicle 1000, so the rotary connecting hole 1201 is disposed on the first connecting seat 120 in this embodiment. Meanwhile, since the first connection base 120 needs to bear the entire weight of the connection mechanism 110 when the connection mechanism 110 is switched to the second state, in order for the first connection base 120 to have a large strength, it is also required to have a certain material thickness and a large external dimension.

If the external dimension of the connection mechanism 110 is too large, the connection mechanism occupies the front space of the electric vehicle 1000 when in the second state, thereby blocking the user from loading and unloading the electric vehicle 1000. Therefore, in the present embodiment, the rotation shaft 1104 having a relatively small external dimension is disposed at the second end 1102 of the connection mechanism 110, so that the external dimension of the connection mechanism 110 is not necessarily limited by the rotational connection structure between the connection mechanism 110 and the carrying mechanism 200.

As shown in fig. 3, in some embodiments, the circumferential wall of the rotary shaft 1104 is provided with an annular groove 1105, and a stopper structure extending into the annular groove 1105 is provided in the rotary connection hole 1201.

Illustratively, the cross-sectional shape of the rotational shaft 1104 may be circular or polygonal.

Illustratively, annular groove 1105 is near the end of rotary shaft 1104.

The annular groove 1105 includes two cell walls that set up along the axis interval of axis of rotation 1104, and limit structure is located between two cell walls, and cell wall and limit structure mutually support can restrict the axis direction's of rotation 1104 removal, avoid coupling mechanism 110 to separate with first connecting seat 120 when rotating.

As shown in fig. 4, in some embodiments, the first connecting seat 120 is provided with a latch hole 1202 communicating with the rotation connecting hole 1201, and the electric vehicle control assembly further includes a limit clip 130 inserted into the first connecting seat 120 through the latch hole 1202, and the limit clip 130 extends into the annular groove 1105 when inserted into the latch hole 1202.

Illustratively, the latch hole 1202 is disposed at the bottom of the first coupling seat 120 and is disposed along the radial direction of the rotation coupling hole 1201.

The limiting clip 130 is illustratively a plate-like structure.

Illustratively, the stop clip 130 can be positioned within the latch hole 1202 of the first connector base 120 by an adhesive connection, a snap fit, a weld, or the like.

Illustratively, the end of the stop clip 130 facing the rotational coupling hole 1201 is in the shape of a concave arc having a size corresponding to the size of the groove bottom of the annular groove 1105.

In assembly, the rotating shaft 1104 of the connecting mechanism 110 is first inserted into the rotating connecting hole 1201 of the first connecting seat 120, and the annular groove 1105 on the rotating shaft 1104 is aligned with the latch hole 1202 of the first connecting seat 120. Then, the limiting clip 130 is inserted into the latch hole 1202 until the end thereof extends into the annular groove 1105 as a limiting structure to limit the connecting shaft.

As shown in fig. 4, in some embodiments, the electric vehicle control assembly includes a second connection seat 140, where the second connection seat 140 is disposed on a side of the carrying mechanism 200 away from the first connection seat 120; the second connecting seat 140 is provided with a limiting part 1401, and the connecting mechanism 110 is in contact with the limiting part 1401 when in the first state; the connection mechanism 110 is separated from the stopper 1401 when in the second state.

The connection manner between the second connection base 140 and the carrying mechanism 200 is the same as the connection manner between the first connection base 120 and the carrying mechanism 200, and will not be described herein.

Illustratively, the stop 1401 is a block-like structure.

When the connection mechanism 110 is in the first state, the second end 1102 of the connection mechanism is supported by the first connection seat 120, and the first end 1103 is abutted against the limiting portion 1401 of the second connection seat 140, i.e. the limiting portion 1401 supports the first end 1103 of the connection mechanism 110, so as to ensure that the connection mechanism 110 in the first state can be stably positioned in front of a user.

As shown in fig. 3 and 4, in some embodiments, a bottom portion of the connection mechanism 110 is provided with a limiting groove 1106 penetrating to the first end 1103, and when the connection mechanism 110 is in the first state, the connection mechanism 110 is plugged against the limiting portion 1401 of the second connection seat 140 through the limiting groove 1106.

Illustratively, the limiting portion 1401 is located at an end of the second connecting seat 140 away from the carrying mechanism 200.

When the connection mechanism 110 is switched from the second state to the first state through the longitudinal rotation, the connection mechanism 110 gradually approaches the second connection seat 140 from top to bottom until the limit portion 1401 on the second connection seat 140 is inserted into the limit groove 1106 of the first end 1103 of the connection mechanism 110 to abut against the groove bottom of the limit groove 1106, and the connection mechanism 110 stops rotating. At this time, the stopper 1401 is configured to support the first end 1103 of the connection mechanism 110, and the connection mechanism 110 can be maintained in the first state.

As shown in fig. 3 and 4, in some embodiments, the limiting portion 1401 is provided with a limiting longitudinal groove 1402 penetrating through the top and the bottom, the notch of the connecting mechanism 110 near the first end 1103 is provided with a limiting piece 1107 in the limiting groove 1106, and when the connecting mechanism 110 is in the first state, the limiting piece 1107 is plugged with the limiting portion 1401 through the limiting longitudinal groove 1402.

Illustratively, the stopper 1401 includes a root fixedly coupled to the other portion of the second connecting seat 140, and an end portion remote from the root. The stopper longitudinal groove 1402 is provided at the root of the stopper 1401.

Illustratively, the spacing pod 1402 is symmetrically disposed about the axis of the spacing portion 1401.

The spacing longitudinal groove 1402 is provided with two cell walls along the axis interval of spacing portion 1401, and when coupling mechanism 110 is from top to bottom near second connecting seat 140 gradually, when spacing portion 1401 inserts spacing groove 1106, spacing piece 1107 inserts between two cell walls of spacing longitudinal groove 1402 to realize the location to coupling mechanism 110, avoid coupling mechanism 110's first end 1103 to remove along the axis direction of spacing portion 1401.

As shown in fig. 1, in some embodiments, the electric vehicle control assembly further includes a direction mechanism 700, the direction mechanism 700 being used to control the electric vehicle to advance or retract.

Illustratively, the steering mechanism 700 may include a linear trigger device. For example: buttons, finger throttle, etc.

The direction mechanism 700 may generate a direction signal based on a trigger operation by a user, and the electric vehicle 1000 may be advanced or retracted according to the direction signal.

In some embodiments, steering mechanism 500 includes a tele-lever mechanism, a handlebar mechanism, or a steering wheel mechanism.

For example, the steering mechanism 700 may be provided on the steering mechanism 500, as in fig. 1.

For example, steering mechanism 700 may be disposed on the same object as steering mechanism 500, e.g., steering mechanism 700 and steering mechanism 500 may both be disposed on the same handle.

For example, the steering mechanism 700 may be disposed on a different object than the steering mechanism 500, for example, the steering mechanism 500 is disposed in a hand operation area, and the steering mechanism 700 is disposed in a foot operation area of the user, and then the user may operate the steering mechanism 500 by hand and trigger the steering mechanism 700 by foot.

In some embodiments, when the steering mechanism 700 is triggered in a first manner, a signal (hereinafter referred to as a forward signal) is generated that controls the forward motion of the electric vehicle 1000; when the direction mechanism 700 is triggered in the second mode, a signal (hereinafter referred to as a back signal) for controlling the back of the electric vehicle 1000 is generated.

In some embodiments, the direction mechanism 700 includes a lever, wherein the first mode includes toggling the lever in a first direction and the second mode includes waving the lever in a second direction, the first direction being different from the second direction;

Or the steering mechanism 700 includes a twist grip throttle, wherein the first mode includes rotating the twist grip throttle in a third direction and the second mode includes rotating the twist grip throttle in a fourth direction, the third direction being opposite the fourth direction.

Wherein the direction mechanism 700 may be a single operating mechanism, the user changing the state of the direction mechanism 700 by different triggering operations, thereby generating different signals. The first direction and the second direction may refer to opposite directions, for example, an up-down direction, a left-right direction. The third direction and the fourth direction may refer to opposite directions, such as front-to-back directions. In particular, the direction mechanism 700 may be a lever that a user may toggle to the left to generate a forward signal; the thumb lever may be toggled to the right to generate a back signal; or the user may toggle the lever to the right to generate a forward signal; the lever may be toggled to the left to generate a back signal. In the example, the steering mechanism 700 may be a twist grip throttle, and the user may rotate the twist grip throttle forward to generate a forward signal; the throttle of the twist grip can be rotated rearward to generate a reverse signal.

The direction mechanism 700 may be a plurality of operation mechanisms, and the user may trigger different operation mechanisms to generate different signals.

As shown in fig. 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 including one of a dial throttle, a twist grip throttle, or a pressure sensor, the second steering mechanism 720 being of the same type as the first steering mechanism 710; wherein the first direction mechanism 710 and the second direction mechanism 720 are disposed at the same side, two sides or middle position of the steering mechanism 500.

Illustratively, the first and second steering mechanisms 710, 720 are symmetrically disposed on the steering mechanism 500. Specifically, as shown in fig. 3, the middle position of the steering mechanism 500 may be provided with a shaft structure such that the steering mechanism 500 is rotatably provided to the connection mechanism 110, and the first direction mechanism 710 and the second direction mechanism 720 are symmetrically provided with respect to the middle position of the steering mechanism 500. Thus, the steering mechanism 500 and the steering mechanism 700 can be conveniently and rapidly operated by a user, so that the user can accurately adjust the steering angle of the electric vehicle, and the user experience is improved.

For example, the first and second direction mechanisms 710, 720 may each be a dial throttle, and as shown in fig. 3, the first direction mechanism 710 may be a forward dial throttle that generates a forward signal when triggered by a user. The second direction mechanism 720 may be a reverse finger throttle that generates a reverse signal when triggered by a user.

And

Acquiring a voltage signal or a current signal from an angle sensor arranged in a matched manner with a steering mechanism of the electric vehicle in response to the steering mechanism of the electric vehicle being triggered;

As shown in fig. 8, the electric vehicle control assembly may further include a control device (not shown) coupled to the angle sensor and the direction mechanism 700 for generating a heading angle signal based on the current signal or the voltage signal and generating a driving signal based on the direction signal and the heading angle signal to drive the electric vehicle 1000 to move. For example, the control device may comprise a processor (e.g. an MCU, micro control unit). The drive signal may include a forward rotation or a 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 device transmitting the drive signal to the drive mechanism.

Illustratively, the electric vehicle 1000 may further include a driving mechanism (not shown) electrically connected with the control device and the driving wheel 400 for controlling the rotation of the driving wheel 400 based on a driving signal generated by the control device; and a driving actuator (not shown) coupled to the driving mechanism for driving the rotation of the driving wheel 400 based on the driving force of the driving mechanism to move the electric vehicle 1000.

Specifically, the user may operate the steering mechanism 500 and trigger the steering mechanism 700, the angle sensor detects the rotation angle of the steering mechanism 500 and outputs a responsive voltage signal, and the steering mechanism 700 emits a forward signal or a backward signal. The control device converts the voltage signal output by the angle sensor into a course angle signal.

Specifically, for a differential chassis with double rear drive motors, course control and forward and backward control can be realized through the differential speed of the rear wheels and the double motors; for a single-motor-driven and electric control ackerman steering chassis, steering control is realized by controlling front wheel ackerman steering through the steering mechanism, and the double rear wheels respond to turning and control forward and backward through the cooperation of a single motor and mechanical differential; for the chassis with four Mecanum wheels independently driven, turning, advancing, backing and the like are realized through the control of four-wheel steering.

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

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

Specifically, when a user takes an electric vehicle, the steering mechanism can be controlled by one or both hands, and when the steering mechanism is rotated, the angle sensor detects the rotation angle alpha of the steering mechanism and outputs a corresponding current signal or voltage signal. The user may also manually activate a steering mechanism, such as by manually toggling a finger throttle, manually toggling a lever, manually activating a pressure sensor, manually turning a twist grip throttle forward (e.g., clockwise) or backward (e.g., counter-clockwise), or by foot controlling a foot throttle, etc., to generate a corresponding forward signal or reverse signal. The control device converts the current signal or the voltage signal into a course angle signal with respect to the rotation angle α, and converts the forward signal or the backward signal into a driving signal in combination with the course angle signal. The control device sends the driving signal to the driving mechanism, a motor and a differential mechanism in the driving mechanism control driving wheels based on the driving signal, and the driving executing mechanism cooperates with the driving mechanism to execute forward or backward steering of the electric carrier by rotating the rotating angle of the steering mechanism by a user.
