Therefore, the kart frame is not provided with a circuit control board, a battery is not required to be installed, a mobile phone APP is not required to be downloaded, and Bluetooth pairing or any communication line is not required to be installed; the rodless balance car 400 may be placed into the power assembly mechanism 100 during installation.

Here, that the left rotating shaft 103 and the right rotating shaft 104 are both located on the outer side of the balance vehicle 400 means that the left rotating shaft 103 is located on the left side of the left wheel 403 of the balance vehicle 400, and the right rotating shaft 104 is located on the right side of the right wheel 404 of the balance vehicle 400.

In other embodiments, the balance car 400 can also be installed at the front end of the kart frame, and the corresponding assembly mechanism 100 is also located at the front half section of the frame body.

In this embodiment, the frame body includes a main support frame 501, a seat 502 and a connecting frame 503, the wheels and the main support frame 501 are respectively mounted at the front and rear ends of the connecting frame 503, the seat 502 is fixedly mounted above the main support frame 501, and the left and right sides of the assembly mechanism 100 are respectively hinged to the main support frame 501 through a left rotating shaft 103 and a right rotating shaft 104; further preferably, two wheels are mounted at the front end of the connecting frame 503, and the wheels are universal wheels, and in other embodiments, only one wheel may be mounted at the front end of the connecting frame 503.

In this embodiment, the mounting mechanism 100 includes a left mounting bracket 105, a right mounting bracket 106, a left fixing member 107, and a right fixing member 108;

the left fixing piece 107 is installed on the left assembly frame 105 and is fixedly connected with the left platform of the balance car 400, and the left contact piece 101 is installed on the left assembly frame 105; the right fixing piece 108 is installed on the right assembly frame 106 and is fixedly connected with the right platform of the balance car 400, and the right contact piece 102 is installed on the right assembly frame 106;

the left mounting bracket 105 is hinged with the main support frame 501 through a left rotating shaft 103, and the right mounting bracket 106 is hinged with the main support frame 501 through a right rotating shaft 104.

It should be noted that, the left rotating shaft 103 may be fixedly connected to or integrally formed with the left mounting bracket 105, or may be fixedly connected to or integrally formed with the main supporting frame 501; the right rotating shaft 104 can be fixedly connected with or integrally formed with the right assembly frame 106, and also can be fixedly connected with or integrally formed with the main support frame 501; and;

considering the left and right rotation shafts 103 and 104 as main force receiving members, the left and right rotation shafts 103 and 104 have high strength.

In this embodiment, the central axis of the left rotating shaft 103 is parallel to the ground and its height from the ground is H1, the central axis of rotation of the left wheel 403 of the balance car is parallel to the ground and its height from the ground is H2, the central axis of the right rotating shaft 104 is parallel to the ground and its height from the ground is H3, the central axis of rotation of the right wheel 404 of the balance car is parallel to the ground and its height from the ground is H4;

wherein H1 is less than or equal to H2+3cm, and H3 is less than or equal to H4+3cm.

The central axis of the left rotating shaft 103 is distributed in parallel with the rotating central axis of the balance car left wheel 403, and the distance between the projection line of the central axis of the left rotating shaft 103 on the horizontal plane and the projection line of the rotating central axis of the balance car left wheel 403 on the horizontal plane is less than or equal to 3cm; the central axis of the right rotating shaft 104 is parallel to the rotating central axis of the right wheel 404 of the balance car, and the distance between the projection line of the central axis of the right rotating shaft 104 on the horizontal plane and the projection line of the rotating central axis of the right wheel 404 of the balance car on the horizontal plane is less than or equal to 3cm.

Or; the distance between the central axis of the left rotating shaft 103 and the rotating central axis of the left wheel 403 of the balance car 400 is not more than 3cm, and the distance between the central axis of the right rotating shaft 104 and the rotating central axis of the right wheel 404 of the balance car 400 is not more than 3cm; compared with the existing karts of the same type, the distance between the central axis of the rotating shaft and the rotating central axis of the wheels of the balance car 400 is at least reduced by more than 3cm, so that the interference between the balance car 400 and the whole motion of the frame during swinging is relieved; further preferably, the distance between the central axis of the left rotating shaft 103 and the rotating central axis of the left wheel 403 of the balance car 400 is not more than 1cm; the distance between the central axis of the right rotating shaft 104 and the rotating central axis of the right wheel 404 of the balance car 400 is not more than 1cm; thus, the interference generated by the overall motion of the balance car 400 and the frame when the balance car swings is greatly reduced.

The projection line of the connecting line between the central point of the left rotating shaft 103 and the rotating central point of the left wheel 403 of the balance car 400 on the side view plane of the car body is parallel to the gravity line of the earth; the projection line of the connecting line between the central point of the right rotating shaft 104 and the rotating central point of the right wheel 404 of the balance car 400 on the side view plane of the car body is parallel to the gravity line of the earth.

Most preferably, the central axis of the left rotating shaft 103 is distributed coaxially with the rotation central axis of the left wheel 403 of the balance vehicle 400; the central axis of the right rotating shaft 104 and the rotating central axis of the right wheel 404 of the balance car 400 are distributed coaxially;

the arrangement is that in the current kart adopting the balance car 400 as the rear driving force, due to structural limitation, the swing central axis of the assembly mechanism 100 and the rotation central axis of the wheels of the balance car 400 are often spaced by more than 5cm, and the assembly mechanism 100 and the balance car 400 are fixedly connected to form a whole, so that two rotation central axes appear when the assembly mechanism 100 is operated to swing, the two rotation axes can cause motion interference between the swing of the assembly mechanism 100 and the swing of the balance car 400, and the larger the distance between the two rotation axes is, the stronger the motion interference is; the existing kart mainly depends on strong force to twist the whole balance car 400 and the connecting part 1073 to eliminate movement interference, so that the operation resistance of the kart is very large, and parts of the balance car 400 are seriously abraded; when the swing central shaft of the assembly mechanism 100 and the rotation central shaft of the wheels of the balance car 400 are coaxially distributed, the change of the height of the gravity center of the frame and the horizontal position cannot be caused when the balance car 400 is operated to swing back and forth, the problem that the gravity needs to be overcome to do work due to the change of the height of the gravity center of the frame during operation is avoided, the interference and the conflict between the swing of the balance car 400 and the overall motion of the frame are avoided, the operation of the kart car is most flexible, and the abrasion to the parts of the balance car 400 is minimum.

It should be noted that, for the same type of balance car 400, the positions of the left rotating shaft 103 and the right rotating shaft 104 can be completely designed to be coaxial with the left and right wheels 404 of the adapted balance car 400, but the balance cars 400 commonly found on the market at present mainly include three types of 6.5 inch balance cars 400, 8.5 inch balance cars 400 and 10 inch balance cars 400, and since the assembly mechanism 100 is fixedly mounted on the balance car 400 by clamping, the coaxiality of the left rotating shaft 103 and the right rotating shaft 104 with the wheels of the balance car 400 in the horizontal direction does not change due to the change of the size of the balance car 400, and in order to ensure the coaxiality of the left rotating shaft 103 and the right rotating shaft 104 with the wheels of the balance car 400 in the vertical direction, in this embodiment, the assembly mechanism 100 further includes an adjusting assembly 109 for adjusting the height of the assembly mechanism 100 from the ground, so that the left rotating shaft 103 and the right rotating shaft 104 both have three mounting positions with different heights to respectively correspond to the right wheels 404 and the 6.5 inch balance cars 400 and 8.5 inch balance cars 400 and 10 inch balance cars 400; and has two different embodiments:

Specifically, as shown in fig. 13, the left fixing member 107 includes a front fixing portion 1071, a rear fixing portion 1072, and a connecting portion 1073 for connecting the front fixing portion 1071 and the rear fixing portion 1072, the front fixing portion 1071 and the rear fixing portion 1072 having a staying position for clamping the front and rear sides of the balance car 400 by the connecting portion 1073 and a staying position away from the front and rear sides of the balance car 400; the front end and the rear end of the connecting part 1073 respectively extend downwards to form a front step and a rear step, the bottom surface of the front step and the bottom surface of the rear step are both abutted against the platform of the balance car 400, and the middle part of the connecting part 1073 is suspended above the balance car 400; thus, the weight of the frame and the rider cannot directly press the pedal part of the balance car 400, and the weight of the frame and the rider cannot trigger the pedal switch of the balance car 400, so that the phenomenon that the rider still runs after the kart is not parked or dismounted is avoided, and the phenomenon that the rider runs just after the kart is parked but not prepared.

The right fixing member 108 has the same structure as the left fixing member 107, and is not described in detail here.

It should be noted that, in the present application, the platform on the balance vehicle 400 refers to an end surface of the balance vehicle 400 having the left footrest portion 401 and the right footrest portion 402; and

With this arrangement, the left and right stepping portions 401 and 402 can be maximally stepped by the dummy in the process of getting on and off the balance car 400, and the balance car 400 can not enter the running state even if the left and right contact members 101 and 102 abut against the left and right stepping portions 401 and 402, respectively.

It should be noted here that the left mounting bracket 105 and the right mounting bracket 106 may be two independent components, there is no connection relationship between the two, and the left mounting bracket 105 and the right mounting bracket 106 may also be fixedly connected or integrally formed through a connecting member to form a whole;

in addition, as shown in fig. 10, the left mounting bracket 105 and the right mounting bracket 106 can be movably connected with the connecting member to form a whole, so that the distance between the left mounting bracket 105 and the right mounting bracket 106 can be adjusted to adapt to balance cars 400 with different sizes.

In the first embodiment, the left mounting bracket 105 and the right mounting bracket 106 can be two independent components without connection relationship, specifically:

as shown in fig. 1 to 3, the left mounting bracket 105 includes a first left mounting member 115 and a second left mounting member 116, which are fixedly connected or integrally formed, a left side of the first left mounting member 115 is hinged to the kart frame through a left rotating shaft 103, and the second left mounting member 116 is fixedly connected to a left platform of the balance car 400 through a left fixing member 107;

In this way, the first left fitting part 115 and the first right fitting part 120 cooperate to enclose the balance car 400 therein, so as to prevent the kart car from damaging the balance car 400 in case of collision.

The control mechanism comprises a left control assembly and a right control assembly, the left control assembly comprises a left control pedal 201 and a control connecting assembly 202, the left control pedal 201 is rotatably arranged on the connecting frame 503, and the left assembling frame 105 is controlled to rotate through the control connecting assembly 202; further preferably, the manipulating connecting assembly 202 uses a link mechanism to control the rotation of the left mounting bracket 105; specifically, the left support frame comprises a first connecting rod and a second connecting rod, wherein the rear end of the first connecting rod is fixedly connected with or integrally formed with the left operating pedal 201, the front end of the first connecting rod is hinged with the front end of the second connecting rod, and the rear end of the second connecting rod is hinged with the front end of the left support frame;

the right manipulating component and the left manipulating component have the same structure and are not described in detail here.

In other embodiments, the structure of the left and right mounting brackets 105, 106 may be further optimized to save material, and in particular, as shown in figure 9,

the first left assembly member 115 is a single beam positioned on the left side of the balance car 400, and the second left assembly member 116 comprises a left cantilever beam for mounting the left fixing member 107, wherein the left cantilever beam is in a front-back direction or a left-right direction;

the first right assembly 120 is a single beam located at the right side of the balance car 400, and the second right assembly 117 includes a right cantilever beam for mounting the right fixing member 108, and the right cantilever beam is in a front-back direction or a left-right direction.

The specific control method of the kart comprises the following steps:

when the left operating pedal 201 is subjected to an acting force applied by the left foot of an operator, the left operating pedal 201 can generate an inclined deflection stroke in a corresponding direction, the swing stroke is transmitted to the assembly mechanism 100 through the operating connection assembly 202, so that the left assembly frame 105 generates corresponding inclined deflection, the left assembly frame 105 drives the left platform of the balance car 400 assembly to generate a corresponding inclined deflection angle, and therefore the left wheel of the balance car 400 assembly is operated to output a corresponding rotating direction and a corresponding rotating speed;

when the right operating pedal 203 is acted by the right foot of the operator, the right operating pedal 203 generates a tilting deflection stroke in a corresponding direction, the swinging stroke is transmitted to the assembly mechanism 100 through the operating connecting component 202, so that the right assembly frame 106 generates corresponding tilting deflection, the right assembly frame 106 drives the right platform of the balance vehicle 400 component to generate a corresponding tilting deflection angle, and therefore the right wheel of the balance vehicle 400 component is operated to output a corresponding rotating direction and a corresponding rotating speed.

Further preferably, when the left operating pedal 201 and the right operating pedal 203 are stepped on to be inclined forwards and deflected by the same angle, the left platform of the balance car 400 and the right platform of the balance car 400 generate the same inclined deflection angle, the components of the balance car 400 output torque forwards, the kart runs forwards, and the larger the angle of inclined forward deflection of the left operating pedal 201 and the right operating pedal 203 is, the faster the kart runs;

when the left operating pedal 201 and the right operating pedal 203 are stepped on to tilt backwards by the same angle, the left platform of the balance vehicle 400 and the right platform of the balance vehicle 400 generate corresponding tilt deflection angles, the components of the balance vehicle 400 output torque backwards, and the kart runs backwards, wherein the larger the angle of the left operating pedal 201 and the right operating pedal 203 which tilt backwards is, the faster the kart runs backwards.

Further preferably, when the left operating pedal 201 and the right operating pedal 203 are stepped on by different tilt deflection angles or in opposite tilt deflection directions, the left platform of the balance vehicle 400 and the right platform of the balance vehicle 400 generate different tilt deflection angles to cause the left and right wheels 404 of the components of the balance vehicle 400 to output different rotation speeds or different rotation directions, and the speed difference of the left and right wheels 404 drives the kart to steer.

Further preferably, when the left operating pedal 201 and the right operating pedal 203 are simultaneously stepped on in the direction opposite to the driving direction of the kart, the balance car 400 assembly outputs reverse torque, and the kart decelerates; when the left operating pedal 201 and the right operating pedal 203 are stepped in the same direction as the driving direction of the kart, the balance car 400 assembly outputs positive torque, and the kart is accelerated.

In the second embodiment, the left mounting bracket 105 and the right mounting bracket 106 are fixed or integrally formed to be a non-rotatable whole, and specifically:

the first left assembly member 115 is fixedly connected with or integrally formed with the first right assembly member 120; alternatively, the second left fitting 116 and the second right fitting 117 are fixedly connected or integrally formed.

The arrangement enables the left platform and the right platform of the balance car 400 to swing only along the same angle, so that the balance car 400 does not have the autonomous steering function any more, and therefore, a steering wheel 204 assembly is required to be arranged on the kart to control steering of the kart, and the specific structure of the kart can refer to the structure of the steering wheel 204 in the publication No. CN 110281783A.

The control mechanism can adopt a link mechanism with the same structure as that of the first case, and can also adopt a pull rope 213 or a chain mechanism;

the specific control method of the kart in this embodiment may be similar to that in the first embodiment, that is, the left operating pedal 201 and the right operating pedal 203 are stepped on to swing forward or backward, specifically:

when the left operating pedal 201 or the right operating pedal 203 is treaded to tilt forwards, the left platform of the balance vehicle 400 and the right platform of the balance vehicle 400 generate the same tilting deflection angle, so that the kart has forward acceleration, and the greater the tilting deflection angle of the left operating pedal 201 or the right operating pedal 203 is, the greater the forward speed of the kart is;

when the left operating pedal 201 or the right operating pedal 203 is stepped on to deflect backwards, the left platform of the balance vehicle 400 and the right platform of the balance vehicle 400 generate corresponding inclined deflection angles, so that the kart has backward acceleration, and the backward speed of the kart is higher as the left operating pedal 201 or the right operating pedal 203 deflects backwards by a larger angle.

When the left operating pedal 201 and the right operating pedal 203 can only be stepped on to swing forwards, the specific control method of the kart in the embodiment can also be as follows:

when the left operating pedal 201 is turned forward forwards, the assembling mechanism 100 tilts forwards and deflects, so that the kart has forward acceleration, and the larger the amplitude of the forward tilting deflection of the left operating pedal 201 is, the larger the forward speed of the kart is;

when the right operating pedal 203 is stepped on to deflect forwards, the assembly mechanism 100 deflects backwards so that the kart has a backward acceleration, and the greater the magnitude of the forward deflection that the left operating pedal 201 is stepped on, the greater the backward speed of the kart.

It should be noted that the switch structure and the operation structure in this embodiment can also be used for a kart with a left rotating shaft 103 and a right rotating shaft 104 built therein.

The second embodiment:

compared with the first embodiment, the control mechanism in the embodiment does not control the advance, the retreat, the acceleration and the deceleration of the kart through the left control pedal 201 and the right control pedal 203 any more; but controls the advance, retreat, acceleration and deceleration of the kart through the steering wheel 204 component; of course, the steering wheel 204 assembly may still be used to control steering of the kart;

and the left mounting bracket 105 and the right mounting bracket 106 in the present embodiment are fixedly connected or integrally formed by a connecting member.

Further preferably, a limiting hole 504 is formed in the main support frame 501, and the power control connecting rod 210 extends into the limiting hole 504; therefore, the swing of the power control connecting rod 210 is limited, and the whole operation control mechanism is limited.

the first locking lever 215 is movably mounted on the steering wheel 204 and causes the locking member 211 to have a third rest position and a fourth rest position; in the process that the first locking lever 215 drives the locking piece 211 to move from the third stop position to the fourth stop position, the first locking lever 215 pulls the pull cable 213 to drive the locking piece 211 to slide in the direction away from the first axial long hole 2160, so that the power control swing rod 207 is in an unlocked state; in the process that the first locking lever 215 drives the locking member 211 to move from the fourth stop position to the third stop position, the locking member 211 slides toward the first axial long hole 2160 under the action of the tension spring 214 until the fixing pin 225 is located in the first notch 2110, so that the power control swing link 207 is in the locked state.

Further preferably, both sides of the first notch 2110 are provided with a round corner; such an arrangement can facilitate entry of the retaining pin 225 into the first notch 2110.
