Description

Technical Field

[0001] This invention relates to the field of transportation and amusement equipment technology, and in particular to a go-kart, its frame, and a control method thereof. Background Technology

[0002] Self-balancing scooters, also known as hoverboards, operate on the principle of "dynamic stabilization." They utilize internal gyroscopes and accelerometers to detect changes in the scooter's posture and employ a servo control system to precisely drive the motors to make corresponding adjustments, maintaining system balance. They are a new type of green and environmentally friendly product used by modern people for transportation and leisure. Based on different control methods, self-balancing scooters on the market are mainly divided into two categories: poleless self-balancing scooters and pole-mounted self-balancing scooters. Poleless self-balancing scooters are characterized by flexible handling and high playability, but due to their electric balancing principle, they pose certain safety risks during use. Traditional pole-mounted electric self-balancing scooters or skateboards are generally used for transportation and lack entertainment value.

[0003] Therefore, power sources that use self-balancing scooters for go-karts have gradually appeared on the market.

[0004] In the initial design, the front of the go-kart frame was directly connected to the central pivot of the self-balancing scooter via a circular clamp. The operator sat behind and placed their feet on the footrests of the self-balancing scooter. In this type of go-kart, the weight of the front part of the frame was directly pressed onto the central pivot of the self-balancing scooter via the circular clamp, which caused the pivot to be subjected to very large flexural forces, potentially leading to deformation or breakage.

[0005] Another type of go-kart includes a frame with a self-balancing scooter attached to the bottom of one end of the frame. An electronically controlled steering wheel is located on the upper part of the frame near the self-balancing scooter. The electronically controlled steering wheel is wirelessly connected to the self-balancing scooter via a first wireless transmission module. At least one wheel is located at the bottom of the other end of the frame. This type of go-kart effectively solves the aforementioned technical problems by using electronic control, but it has poor versatility, requires a specific self-balancing scooter to use, and also requires a mobile app to set up the self-balancing scooter and frame controller, resulting in higher costs. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to overcome the shortcomings of the prior art by providing a go-kart, its frame, and a control method. This frame does not require the use of a mobile app to configure the balance scooter and frame controller, resulting in low cost.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0034] A method for controlling a go-kart, using a go-kart as described above; wherein:

[0035] When both the left and right control pedals are pressed and the car tilts forward, the go-kart has forward speed.

[0036] When both the left and right control pedals are pressed and tilted backward, the go-kart has a backward speed.

[0037] When the left and right control pedals are pressed and the tilt angles are different or the tilt directions are opposite, the go-kart enters the steering state.

[0040] 2) In this technical solution, the left control pedal controls the left half of the balance car, and the right control pedal controls the right half of the balance car. This allows the go-kart frame to make full use of the performance of the balance car, that is, to use the characteristics of the balance car itself to achieve the go-kart turning, thereby eliminating the need for the steering wheel part of the go-kart. It is highly maneuverable and also allows people with disabilities who have no hands to enjoy the fun of go-karting. Attached Figure Description

[0059] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0060] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more, unless explicitly defined otherwise.

[0062] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In this invention, "parallel" is not limited to theoretical absolute parallelism, but also allows for an error of ±3°; and "coaxial" is not limited to theoretical absolute coaxiality, but also allows for an error of ±5mm.

[0065] Example 1:

[0066] like Figure 1-3 The go-kart shown includes a go-kart frame and a self-balancing scooter 400, which is mounted at the rear end of the go-kart frame to serve as a power source for the go-kart's movement.

[0067] The self-balancing scooter 400 utilizes an internal gyroscope and accelerometer to detect changes in the scooter's posture and employs a servo control system to precisely drive the motors for corresponding adjustments, maintaining system balance. It is a new type of green and environmentally friendly product used by modern people for transportation and leisure. Generally, its operation method is as follows:

[0068] A person can turn on the self-balancing scooter 400 by placing their feet on the left footrest 401 and the right footrest 402 respectively, and put the self-balancing scooter 400 into a driving state. Alternatively, the self-balancing scooter 400 can be turned on by pressing the switch button on the self-balancing scooter 400, and then put into a driving state by placing their feet on the left footrest 401 and the right footrest 402 respectively.

[0069] Then, by controlling the left foot pedal 401 and the right foot pedal 402 with the person's two feet, the left wheel 403 and the right wheel 404 of the balance vehicle 400 can be tilted forward or backward, so that the left wheel 403 and the right wheel 404 of the balance vehicle 400 can move forward, accelerate, move backward, decelerate and turn.

[0070] Depending on whether the left foot pedal 401 and the right foot pedal 402 on the self-balancing scooter 400 can twist relative to each other, the self-balancing scooter 400 can be divided into a regular self-balancing scooter 400 and a twist self-balancing scooter 400; the go-kart frame in this embodiment is applicable to both regular self-balancing scooters 400 and twist self-balancing scooters 400.

[0071] like Figure 1-3 As shown, the go-kart frame includes a frame body, an assembly mechanism 100, and a control mechanism. At least one wheel is mounted on the front end of the frame body. The assembly mechanism 100 is located in the rear half of the frame body and is fixedly connected to the self-balancing vehicle 400. The assembly mechanism 100 is provided with a left contact member 101 for contacting the left foot pedal 401 of the self-balancing vehicle 400 and a right contact member 102 for contacting the right foot pedal 402 of the self-balancing vehicle 400. The left and right sides of the assembly mechanism 100 are hinged to the frame body through a left pivot 103 and a right pivot 104, respectively. Both the left pivot 103 and the right pivot 104 are located on the outside of the self-balancing vehicle 400. The control mechanism is used to control the tilt of the assembly mechanism 100, thereby controlling the go-kart's forward movement, acceleration, backward movement, deceleration, and steering.

[0072] In this way, the go-kart frame has no circuit control board, does not require the installation of batteries, does not require downloading a mobile APP, and does not require Bluetooth pairing or the installation of any communication cables; during installation, simply place the poleless self-balancing scooter 400 into the power assembly mechanism 100.

[0073] It should be noted that when the left turning axle 103 and the right turning axle 104 are both located on the outside of the self-balancing vehicle 400, it means that the left turning axle 103 is located on the left side of the left wheel 403 of the self-balancing vehicle 400, and the right turning axle 104 is located on the right side of the right wheel 404 of the self-balancing vehicle 400.

[0074] In other embodiments, the self-balancing scooter 400 can also be installed at the front end of the go-kart frame, and the corresponding assembly mechanism 100 is also located in the front half of the frame body.

[0075] In this embodiment, the main body of the frame includes a main support frame 501, a seat portion 502, and a connecting frame 503. The wheels and the main support frame 501 are respectively installed at the front and rear ends of the connecting frame 503. The seat portion 502 is fixedly installed above the main support frame 501. The left and right sides of the assembly mechanism 100 are hinged to the main support frame 501 through a left pivot 103 and a right pivot 104, respectively. More preferably, two wheels are installed at the front end of the connecting frame 503. The wheels are omnidirectional wheels. In other embodiments, only one wheel may be installed at the front end of the connecting frame 503.

[0076] In this embodiment, the assembly mechanism 100 includes a left assembly frame 105, a right assembly frame 106, a left fixing member 107, and a right fixing member 108;

[0077] The left fixing member 107 is installed on the left assembly frame 105 and is fixedly connected to the left platform of the self-balancing vehicle 400; the left contact member 101 is installed on the left assembly frame 105; the right fixing member 108 is installed on the right assembly frame 106 and is fixedly connected to the right platform of the self-balancing vehicle 400; the right contact member 102 is installed on the right assembly frame 106.

[0078] The left assembly frame 105 is hinged to the main support frame 501 via a left pivot 103, and the right assembly frame 106 is hinged to the main support frame 501 via a right pivot 104.

[0079] It should be noted that the left rotating shaft 103 can be fixedly connected to or integrally formed with the left assembly frame 105, or fixedly connected to or integrally formed with the main support frame 501; the right rotating shaft 104 can be fixedly connected to or integrally formed with the right assembly frame 106, or fixedly connected to or integrally formed with the main support frame 501; and;

[0080] Considering that the left rotating shaft 103 and the right rotating shaft 104 are the main load-bearing components, the left rotating shaft 103 and the right rotating shaft 104 have high strength.

[0081] In this embodiment, the central axis of the left rotating shaft 103 is parallel to the ground and its height above the ground is H1; the rotation center axis of the left wheel 403 of the balance vehicle is parallel to the ground and its height above the ground is H2; the central axis of the right rotating shaft 104 is parallel to the ground and its height above the ground is H3; and the rotation center axis of the right wheel 404 of the balance vehicle is parallel to the ground and its height above the ground is denoted as H4.

[0082] Where H1≤H2+3cm, H3≤H4+3cm.

[0083] Furthermore, the central axis of the left turning shaft 103 is parallel to the rotation center axis of the left wheel 403 of the self-balancing scooter, and the distance between the projection line of the central axis of the left turning shaft 103 on the horizontal plane and the projection line of the rotation center axis of the left wheel 403 on the horizontal plane is less than or equal to 3 cm; the central axis of the right turning shaft 104 is parallel to the rotation center axis of the right wheel 404 of the self-balancing scooter, and the distance between the projection line of the central axis of the right turning shaft 104 on the horizontal plane and the projection line of the rotation center axis of the right wheel 404 on the horizontal plane is less than or equal to 3 cm.

[0084] Alternatively; the distance between the central axis of the left swivel 103 and the rotation center axis of the left wheel 403 of the balance vehicle 400 shall not exceed 3cm, and the distance between the central axis of the right swivel 104 and the rotation center axis of the right wheel 404 of the balance vehicle 400 shall not exceed 3cm; in this way, compared with existing go-karts of the same type, the distance between the central axis of the swivel and the rotation center axis of the wheel of the balance vehicle 400 is reduced by at least 3cm, thereby reducing the interference caused by the balance vehicle 400 swinging and the overall movement of the frame; more preferably, the distance between the central axis of the left swivel 103 and the rotation center axis of the left wheel 403 of the balance vehicle 400 shall not exceed 1cm; the distance between the central axis of the right swivel 104 and the rotation center axis of the right wheel 404 of the balance vehicle 400 shall not exceed 1cm; in this way, the interference caused by the balance vehicle 400 swinging and the overall movement of the frame is greatly reduced.

[0085] The projection of the line connecting the center point of the left pivot 103 and the rotation center point of the left wheel 403 of the self-balancing vehicle 400 onto the side view of the vehicle body is parallel to the Earth's gravity line; the projection of the line connecting the center point of the right pivot 104 and the rotation center point of the right wheel 404 of the self-balancing vehicle 400 onto the side view of the vehicle body is parallel to the Earth's gravity line.

[0086] As the most preferred embodiment, the central axis of the left rotating shaft 103 is coaxial with the rotation center axis of the left wheel 403 of the self-balancing vehicle 400; the central axis of the right rotating shaft 104 is coaxial with the rotation center axis of the right wheel 404 of the self-balancing vehicle 400.

[0087] This design is due to structural limitations in current go-karts that use a self-balancing scooter 400 as the rear-mounted drive system. The swing axis of the assembly mechanism 100 and the rotation axis of the self-balancing scooter 400 wheel are often more than 5cm apart. Since the assembly mechanism 100 and the self-balancing scooter 400 are fixedly connected as a single unit, two rotation axes appear when the assembly mechanism 100 swings. These two axes cause motion interference between the swing of the assembly mechanism 100 and the swing of the self-balancing scooter 400. The greater the distance between the two rotation axes, the stronger the motion interference. Currently, go-karts mainly rely on… The go-kart's operation is greatly hampered by the forceful twisting of the entire vehicle and its 1073 connecting parts, resulting in significant wear and tear on the components. However, when the swing center axis of the assembly mechanism 100 is coaxial with the rotation center axis of the wheels, the swinging motion of the go-kart does not cause changes in the height and horizontal position of the frame's center of gravity. This avoids the need to overcome gravity to maintain the balance during operation and prevents interference and conflict between the swinging motion of the go-kart and the overall movement of the frame. This makes the go-kart more agile and minimizes wear on the components.

[0088] It's worth noting that for the same self-balancing scooter 400, the positions of the left axle 103 and right axle 104 could be designed to be coaxial with the left and right wheels 404 of the scooter 400. However, the most common self-balancing scooters 400 on the market are 6.5-inch, 8.5-inch, and 10-inch models. Since the mounting mechanism 100 is fixed to the self-balancing scooter 400 by clamping, the left axle 103 and right axle 104 are not coaxial with the wheels of the self-balancing scooter 400 in the horizontal direction. The axle alignment does not change due to variations in the size of the self-balancing scooter 400. To ensure the coaxiality of the left and right axles 103 and 104 with the wheels of the self-balancing scooter 400 in the vertical direction, in this embodiment, the assembly mechanism 100 further includes an adjustment component 109 for adjusting the height of the assembly mechanism 100 from the ground. This allows the left and right axles 103 and 104 to each have three different mounting positions, corresponding to 6.5-inch, 8.5-inch, and 10-inch self-balancing scooters 400, respectively. Two different implementation methods are also provided.

[0089] The first embodiment: The adjustment component 109 includes two vertically arranged rows of holes on the left and right and two spring pins on the left and right. The holes and spring pins cooperate to allow the left rotating shaft 103 and the right rotating shaft 104 to have multiple installation positions at different heights.

[0090] The left and right rows of insertion holes are located on the left assembly frame 105 and the right assembly frame 106 respectively, and the two spring pins are located on the left and right sides of the main support frame 501 respectively. The left rotating shaft 103 and the right rotating shaft 104 are fixedly connected to the two spring pins or integrally formed.

[0091] In other embodiments, the left and right rows of insertion holes may also be located on the left assembly frame 105 and the right assembly frame 106 respectively, and the two spring pins may be located on the left fixing member 107 and the right fixing member 108 respectively; in other embodiments, the left and right rows of insertion holes may also be located on the left fixing member 107 and the right fixing member 108 respectively, and the two spring pins may be located on the left assembly frame 105 and the right assembly frame 106 respectively.

[0092] The second implementation method: as follows Figure 7-9 As shown, the adjustment assembly 109 includes two screws, left and right; wherein, the left fixing member 107 and the right fixing member 108 are respectively installed on the left assembly frame 105 and the right assembly frame 106 in a manner that allows them to move up and down via the left and right screws, and have multiple stopping positions, so that the left rotating shaft 103 and the right rotating shaft 104 each have multiple installation positions at different heights; or, the left rotating shaft 103 and the right rotating shaft 104 are respectively installed on the left assembly frame 105 and the right assembly frame 106 in a manner that allows them to move up and down via the left and right screws, and have multiple installation positions at different heights.

[0093] Patent documents with publication numbers CN106218781A, CN109533152A, CN110239650A, CN110281783A, CN205675154U, CN205737869U, and CN209833773U disclose specific structures for fixed connection with a self-balancing scooter 400. Generally, it is fixed to the self-balancing scooter 400 by clamping the front and rear sides of the self-balancing scooter 400 and abutting against the upper surface of the self-balancing scooter 400. This obviously touches the left foot pedal 401 and the right foot pedal on the self-balancing scooter 400. The footrest 402 keeps the self-balancing scooter 400 in the open state, which can easily cause the scooter to slip when people get on. Therefore, in this embodiment, the left fixing member 107 and the right fixing member 108 are added with a stepped structure based on the above-mentioned patent documents to prevent the left fixing member 107 and the right fixing member 108 from contacting the left footrest 401 and the right footrest 402 on the self-balancing scooter 400. At the same time, the left contact member 101 is movably mounted on the left mounting frame 105 in a way that allows it to move up and down, and the right contact member 102 is movably mounted on the right mounting frame 106 in a way that allows it to move up and down.

[0094] Specifically, such as Figure 13As shown, the left fixing member 107 includes a front fixing part 1071, a rear fixing part 1072, and a connecting part 1073 for connecting the front fixing part 1071 and the rear fixing part 1072. The front fixing part 1071 and the rear fixing part 1072 have a stopping position clamping the front and rear sides of the self-balancing vehicle 400, and a stopping position away from the front and rear sides of the self-balancing vehicle 400, respectively, through the connecting part 1073. The front and rear ends of the connecting part 1073 extend downward to form a front step and a rear step, respectively. The bottom surfaces of the steps and the rear steps abut against the platform of the self-balancing vehicle 400, thus causing the middle part of the connecting part 1073 to be suspended above the self-balancing vehicle 400. In this way, the weight of the frame and the rider will not directly press on the foot pedal of the self-balancing vehicle 400, and the weight of the frame and the rider will not trigger the foot pedal switch of the self-balancing vehicle 400. This will prevent the go-kart from continuing to move after the rider has not gotten on or off the vehicle, and will also prevent the go-kart from running away before the rider is ready to get on.

[0095] The right fixing member 108 and the left fixing member 107 have the same structure, and will not be described in detail here.

[0096] It should be noted here that, in this application, the platform on the self-balancing scooter 400 refers to one end face of the self-balancing scooter 400 having the left foot pedal 401 and the right foot pedal 402; and

[0097] The left and right fixing parts can be slidably mounted on the connecting part 1073; alternatively, the connecting part 1073 itself can have two swingable connecting rods, and the left and right fixing parts are fixedly mounted on both ends of the connecting part 1073; thus, the front fixing part 1071 and the rear fixing part 1072 can have a stopping position clamping the front and rear sides of the self-balancing vehicle 400, and a stopping position away from the front and rear sides of the self-balancing vehicle 400, through the connecting part 1073; and

[0098] In other embodiments, the left fixing member 107 and the right fixing member 108 may also be fasteners such as clamps or a clamping device; and

[0099] In other embodiments, it is also possible for the middle portion of the connecting part 1073 to make contact with the platform of the self-balancing scooter 400 through other soft materials.

[0100] In this embodiment, as Figure 3 and Figure 8As shown, a switching mechanism is also provided for controlling whether the left contact 101 contacts the left foot pedal 401 and whether the right contact 102 contacts the right foot pedal 402. Specifically, the left contact 101 is mounted on the left mounting bracket 105 or the left fixing member 107 in a way that allows it to move up and down, and the right contact 102 is mounted on the right mounting bracket 106 or the right fixing member 108 in a way that allows it to move up and down. The switching mechanism is used to control the left contact 101 and the right contact 102 to move up and down and have a first stopping position and a second stopping position with different heights. The left and right contact members 101 and 102 are respectively moved upward from the first stop position to the second stop position, and the left and right contact members 101 and 102 disengage from the left and right foot pedals 401 and 402 respectively, so that the self-balancing vehicle 400 exits the driving state; when the left and right contact members 101 and 102 are respectively moved downward from the second stop position to the first stop position, the left and right contact members 101 and 102 abut against the left and right foot pedals 401 and 402 respectively, so that the self-balancing vehicle 400 enters the driving state.

[0101] In this way, the stepping action of a person getting on and off the self-balancing vehicle 400 on the left foot pedal 401 and the right foot pedal 402 can be simulated, which can trigger or not trigger the foot pedal switch of the self-balancing vehicle 400. Specifically, when the go-kart rider is ready, the switch mechanism is operated to move the left contact 101 and the right contact 102 from the second stop position to the first stop position, so that the self-balancing vehicle 400 can enter the driving state. This can effectively avoid the phenomenon that the go-kart runs away as soon as the rider gets on the vehicle but is not ready.

[0102] It is worth noting that in other embodiments, the left contact 101 and the right contact 102 can also be mounted on the main support frame 501 in a vertically movable manner.

[0103] In this embodiment, the switching mechanism includes a control handle 110, two guide rods 111 on the left and right, and two mounting plates 112 on the left and right. The control handle 110 is rotatably mounted on the main support frame 501. The two mounting plates 112 are fixedly connected to the left assembly frame 105 and the right assembly frame 106 respectively or are integrally formed. The mounting plates 112 are provided with guide holes. The bottom end of the guide rod 111 passes through the guide hole and is fixedly connected to the left contact member 101 and the right contact member 102 respectively or is integrally formed. The top end of the guide rod 111 is connected to the control handle 110 through a movable connecting assembly 113. Rotating the control handle 110 causes the guide rod 111 to move up and down in the guide hole.

[0104] In this embodiment, the bottom surface of the left contact 101 includes at least a plane, and when the left contact 101 abuts against the left foot pedal 401 of the balance vehicle 400, the bottom surface of the left contact 101 can at least cover the sensitive area of ​​the foot pedal trigger switch in the area of ​​the left foot pedal 401.

[0105] The bottom surface of the right contact 102 includes at least a plane, and when the right contact 102 abuts against the right foot pedal 402 of the balance vehicle 400, the bottom surface of the right contact 102 can at least cover the sensitive area of ​​the foot pedal trigger switch in the area of ​​the right foot pedal 402.

[0106] Among them, the "foot pedal trigger switch sensitive area" refers to the area on the surface of the left foot pedal 401 and the right foot pedal 402 of the balance bike 400 that can trigger the balance bike 400 to enter the normal driving mode when stepped on by the rider.

[0107] This design can simulate the stepping action of a person getting on and off the self-balancing scooter 400 on the left foot pedal 401 and the right foot pedal 402 to the greatest extent, avoiding the situation where the self-balancing scooter 400 cannot enter the driving state even if the left contact 101 and the right contact 102 are respectively against the left foot pedal 401 and the right foot pedal 402.

[0108] In this embodiment, two buffer components are also provided, which are respectively attached and fixed to the bottom surface of the left contact 101 and the bottom surface of the right contact 102; thus, when the bottom surfaces of the left contact 101 and the right contact 102 respectively abut against the left foot pedal 401 and the right foot pedal 402, they play a buffering role; wherein, the material of the buffer component is preferably a soft material, such as a colloid material.

[0109] In this embodiment, the movable connection assembly 113 uses a linkage, cam, or gear to control the up and down movement of the guide rod 111.

[0110] In other embodiments, the movable connection assembly 113 uses a cable 213 to control the up and down movement of the guide rod 111; more preferably, it is also provided with two left and right spring members 114, which are respectively sleeved on the left and right guide rods 111, the top of the spring member 114 abuts against the mounting plate 112, and the bottom of the spring member 114 abuts against the left contact member 101 / right contact member 102.

[0111] It should be noted that the left assembly frame 105 and the right assembly frame 106 can be two independent components with no connection between them. Alternatively, the left assembly frame 105 and the right assembly frame 106 can be fixedly connected, integrally formed, or formed into a whole through a connector.

[0112] The left assembly frame 105 and the right assembly frame 106 can be fixedly connected to the connector or integrally formed to form a whole. Additionally, as... Figure 10 As shown, the left assembly frame 105 and the right assembly frame 106 can also be movably connected with the connector to form a whole, so that the distance between the left assembly frame 105 and the right assembly frame 106 can be adjusted to accommodate balance vehicles 400 of different sizes.

[0113] In the first embodiment, the left assembly frame 105 and the right assembly frame 106 can be considered as two independent components, with no connection between them. Specifically:

[0114] like Figure 1-3 As shown, the left mounting frame 105 includes a first left mounting part 115 and a second left mounting part 116 that are fixedly connected or integrally formed. The left side of the first left mounting part 115 is hinged to the go-kart frame via a left pivot 103, and the second left mounting part 116 is fixedly connected to the left platform of the balance vehicle 400 via a left fixing part 107.

[0115] The right mounting bracket 106 includes a first right mounting component 120 and a second right mounting component 117 that are fixedly connected or integrally formed. The right side of the first right mounting component 120 is hinged to the go-kart frame via a right pivot 104, and the second right mounting component 117 is fixedly connected to the right platform of the balance vehicle 400 via a right fixing member 108.

[0116] Wherein, the first left mounting part 115 is an L-shaped frame or a three-sided frame located around the left platform of the balance vehicle 400, and the second left mounting part 116 includes a left cantilever beam for installing the left fixing part 107. The left cantilever beam is in the front-back direction or the left-right direction, and the left cantilever beam is located above the first left mounting part 115.

[0117] The first right mounting component 120 is an L-shaped frame or a three-sided frame located around the right platform of the self-balancing scooter 400. The second right mounting component 117 includes a right cantilever beam for mounting the right fixing component 108. The right cantilever beam is located above the first right mounting component 120 and is in the front-back or left-right direction.

[0118] In this way, the first left mounting accessory 115 and the first right mounting accessory 120 can surround the self-balancing scooter 400, preventing damage to the self-balancing scooter 400 in the event of a collision with the go-kart.

[0119] The control mechanism includes a left control component and a right control component. The left control component includes a left control pedal 201 and a control connection component 202. The left control pedal 201 is rotatably mounted on the connecting frame 503 and controls the rotation of the left assembly frame 105 through the control connection component 202. More preferably, the control connection component 202 uses a linkage mechanism to control the rotation of the left assembly frame 105. Specifically, it includes a first link and a second link. The rear end of the first link is fixedly connected to the left control pedal 201 or integrally formed. The front end of the first link is hinged to the front end of the second link, and the rear end of the second link is hinged to the front end of the left support frame.

[0120] The right control component has the same structure as the left control component, and will not be described in detail here.

[0121] In other embodiments, the structure of the left assembly rack 105 and the right assembly rack 106 can be further optimized to save materials, specifically, such as... Figure 9 As shown,

[0122] The first left mounting part 115 is a single beam located on the left side of the balance vehicle 400, and the second left mounting part 116 includes a left cantilever beam for mounting the left fixing part 107, wherein the left cantilever beam is in the front-back direction or the left-right direction.

[0123] The first right mounting component 120 is a single beam located on the right side of the self-balancing scooter 400, and the second right mounting component 117 includes a right cantilever beam for mounting the right fixing component 108, wherein the right cantilever beam is in the front-back direction or the left-right direction.

[0124] The specific control method for go-karts is as follows:

[0125] When the left control pedal 201 is subjected to the force applied by the operator's left foot, the left control pedal 201 will generate a tilting deflection stroke in a corresponding direction. This swing stroke is transmitted to the assembly mechanism 100 through the control connection component 202, causing the left assembly frame 105 to generate a corresponding tilting deflection. The left assembly frame 105 then drives the left platform of the balance vehicle 400 component to generate a corresponding tilting deflection angle, thereby controlling the left wheel of the balance vehicle 400 component to output a corresponding rotation direction and rotation speed.

[0126] When the right control pedal 203 is subjected to the force applied by the operator's right foot, the right control pedal 203 will generate a tilting deflection stroke in a corresponding direction. This swing stroke is transmitted to the assembly mechanism 100 through the control connection component 202, causing the right assembly frame 106 to generate a corresponding tilting deflection. The right assembly frame 106 then drives the right platform of the balance vehicle 400 component to generate a corresponding tilting deflection angle, thereby controlling the right wheel of the balance vehicle 400 component to output a corresponding rotation direction and rotation speed.

[0127] Further preferred, when the left control pedal 201 and the right control pedal 203 are pressed and tilted forward by the same angle, the left platform and the right platform of the self-balancing vehicle 400 produce the same tilt angle, the self-balancing vehicle 400 components output torque forward, and the go-kart moves forward. The greater the angle of the left control pedal 201 and the right control pedal 203 tilting forward, the faster the go-kart moves forward.

[0128] When the left control pedal 201 and the right control pedal 203 are pressed and tilted backward by the same angle, the left platform and the right platform of the self-balancing vehicle 400 will produce corresponding tilting angles. The self-balancing vehicle 400 components output torque backward, and the go-kart moves backward. The greater the tilting angle of the left control pedal 201 and the right control pedal 203, the faster the go-kart moves backward.

[0129] In a further preferred embodiment, when the left control pedal 201 and the right control pedal 203 are pressed and tilted at different angles or in opposite directions, the left platform and the right platform of the self-balancing vehicle 400 will have different tilt angles, resulting in the left and right wheels 404 of the self-balancing vehicle 400 outputting different rotation speeds or different rotation directions. The speed difference between the left and right wheels 404 drives the go-kart to turn.

[0130] Further optimization shows that when the left control pedal 201 and the right control pedal 203 are pressed simultaneously in the opposite direction to the go-kart's direction of travel, the self-balancing vehicle 400 component outputs a reverse torque, causing the go-kart to decelerate; when the left control pedal 201 and the right control pedal 203 are pressed in the same direction as the go-kart's direction of travel, the self-balancing vehicle 400 component outputs a positive torque, causing the go-kart to accelerate.

[0131] In the second embodiment, the left assembly frame 105 and the right assembly frame 106 are fixedly connected or integrally formed to form a non-rotatable whole. Specifically:

[0132] The first left mounting component 115 is fixedly connected to or integrally formed with the first right mounting component 120; or, the second left mounting component 116 and the second right mounting component 117 are fixedly connected to or integrally formed.

[0133] This configuration causes the left and right platforms of the self-balancing scooter 400 to swing at the same angle, thus making the self-balancing scooter 400 no longer have autonomous steering function. Therefore, a steering wheel 204 component needs to be installed on the go-kart to control the steering of the go-kart. The specific structure can be found in the structure of the steering wheel 204 in the publication number CN110281783A.

[0134] The control mechanism can be a linkage mechanism with the same structure as the first case, or it can be a cable 213 or a chain mechanism.

[0135] In this embodiment, the specific control method of the go-kart can be similar to that of the first embodiment, that is, the left control pedal 201 and the right control pedal 203 can swing forward or backward when pressed. Specifically:

[0136] When the left control pedal 201 or the right control pedal 203 is pressed and tilted forward, the left platform and the right platform of the self-balancing vehicle 400 produce the same tilt angle, which gives the go-kart forward acceleration. The greater the angle of the left control pedal 201 or the right control pedal 203 tilting forward, the greater the forward speed of the go-kart.

[0137] When the left control pedal 201 or the right control pedal 203 is pressed and tilted backward, the left platform and the right platform of the self-balancing vehicle 400 generate corresponding tilting angles, giving the go-kart a backward acceleration. The greater the backward tilting angle of the left control pedal 201 or the right control pedal 203, the greater the backward speed of the go-kart.

[0138] When the left control pedal 201 and the right control pedal 203 can only be pressed to swing forward, the specific control method of the go-kart in this embodiment can also be:

[0139] When the left control pedal 201 is pressed and tilted forward, the assembly mechanism 100 tilts forward, giving the go-kart forward acceleration. The greater the angle of tilting forward when the left control pedal 201 is pressed, the greater the forward speed of the go-kart.

[0140] When the right control pedal 203 is pressed and tilted forward, the assembly mechanism 100 tilts backward, giving the go-kart a backward acceleration. The greater the forward tilt of the left control pedal 201, the greater the backward speed of the go-kart.

[0141] It is worth noting that the switch structure and control structure in this embodiment can also be used in the go-karts built into the left turn shaft 103 and the right turn shaft 104.

[0142] Example 2:

[0143] Compared with Embodiment 1, the control mechanism in this embodiment no longer controls the go-kart's forward, backward, acceleration, and deceleration through the left control pedal 201 and the right control pedal 203; instead, it controls the go-kart's forward, backward, acceleration, and deceleration through the steering wheel 204 assembly. Of course, the steering wheel 204 assembly can still be used to control the go-kart's steering.

[0144] In this embodiment, the left assembly frame 105 and the right assembly frame 106 are fixedly connected or integrally formed, or are formed into a whole by a connector.

[0145] like Figure 4-8 as well as Figure 10-15 As shown, the steering wheel 204 assembly includes a steering wheel 204, a steering link 205, and a steering mechanism. The steering wheel 204 is fixedly connected to the steering link 205. The steering link 205 is movably mounted on the connecting frame 503 and can rotate around itself and swing back and forth. The steering link 205 controls the steering of the go-kart's front wheels through the steering mechanism. The steering link 205 drives the assembly mechanism 100 to swing back and forth by manipulating the connecting assembly 202.

[0146] In this way, the forward and backward movement and speed of the go-kart are controlled by pushing or pulling the steering wheel 204 forward or backward. The pushing and pulling action of the steering wheel 204 controls the tilting direction and angle of the balance vehicle 400 located below the rear of the frame through the power control linkage 210 and the assembly mechanism 100. The greater the forward or backward movement of the steering wheel 204, the greater the tilting angle of the balance vehicle 400 located below the rear of the frame.

[0147] Preferably, the control connection assembly 202 includes a power control link 210, and the direction link 205 is connected to the assembly mechanism 100 through the power control link 210. The front end of the power control link 210 is directly or indirectly movably connected to the direction link 205, and the rear end of the power control link 210 is directly or indirectly hinged to the assembly mechanism 100. The direction link 205 swings forward to drive the assembly mechanism 100 to swing forward, and the direction link 205 swings backward to drive the assembly mechanism 100 to swing backward.

[0148] Preferably, the control connection assembly 202 further includes a power control lever 207, and the directional link 205 is also provided with a mounting base 216 with a first axial elongated hole 2160. The bottom end of the power control lever 207 is hinged to the connecting frame 503, and the top end of the power control lever 207 is movably installed in the first axial elongated hole 2160 by a fixing pin 225 and can move along the first axial elongated hole 2160. The front end of the power control link 210 is hinged to the middle part of the power control lever 207.

[0149] It is worth noting that in other embodiments, it is also feasible to replace the first axial elongated hole 2160 with a groove-like structure.

[0150] In a further preferred embodiment, the main support frame 501 is provided with a limiting hole 504, and the power control link 210 extends into the limiting hole 504; in this way, the limiting of the swing of the power control link 210 is realized to limit the entire control mechanism.

[0151] In a further preferred embodiment, a left-right hinge rod 209 is also provided, with the left and right ends of the hinge rod 209 being fixedly connected to the left assembly frame 105 and the right assembly frame 106 respectively, and the rear end of the power control linkage 210 being hinged to the middle part of the hinge rod 209.

[0152] Preferably, a steering rod 206 is also provided, which is mounted on the connecting frame 503 in a manner that allows it to rotate around itself. The steering link 205 and the steering rod 206 form an obtuse angle. The front end of the steering link 205 is fixedly connected to the steering wheel 204, and the rear end of the steering link 205 is movably connected to the top end of the steering rod 206 so that the steering link 205 can swing back and forth. The steering rod 206 controls the steering of the go-kart's front wheels through a steering mechanism.

[0153] In a further preferred embodiment, the bottom end of the directional link 205 is connected to the top end of the steering link 206 via a universal joint.

[0154] In this way, the steering linkage 205 can swing back and forth on the steering rod 206 to drive the assembly mechanism 100 to swing back and forth, and at the same time, the steering linkage 205 can rotate around itself to drive the steering rod 206 to rotate around itself to drive the front wheels of the go-kart to steer.

[0155] It should be noted that the specific structure of the steering mechanism can be found in the contents disclosed in CN110239650A, CN209833773, and CN110281783A regarding the steering wheel 204 controlling the steering of the two front wheels of the go-kart.

[0156] In this embodiment, a locking mechanism is also provided to prevent the manipulation connection assembly 202, steering wheel 204 assembly or assembly mechanism 100 from swinging back and forth.

[0157] One embodiment of the locking mechanism is to prevent the power control lever 207 in the control connection assembly 202 from swinging back and forth, thereby keeping the steering wheel 204 assembly and the mounting mechanism 100 in a locked state, such as... Figure 14-17 As shown, its specific structure includes a locking element 211, a locking cover 212, a cable 213, a tension spring 214, and a first locking rod 215.

[0158] The locking cover 212 is mounted on the mounting base 216 and cooperates with the mounting base 216 to form a sliding cavity that can accommodate the sliding of the locking member 211;

[0159] The sliding direction of the locking member 211 in the sliding cavity is perpendicular to the first axial elongated hole 2160; the locking member 211 has a first notch 2110 on the side near the first axial elongated hole 2160 that cooperates with the fixing pin 225.

[0160] The bottom end of the cable 213 passes through the locking cover 212 and is connected to the locking member 211, and the top end of the cable 213 is connected to the first locking rod 215.

[0161] The tension spring 214 is sleeved on the cable 213, and the tension spring 214 is located between the locking member 211 and the locking cover 212;

[0162] The first locking lever 215 is movably mounted on the steering wheel 204, giving the locking member 211 a third stopping position and a fourth stopping position. During the process of the first locking lever 215 moving the locking member 211 from the third stopping position to the fourth stopping position, the first locking lever 215 pulls the cable 213 to move the locking member 211 away from the first axial elongated hole 2160, thereby making the power control lever 207 in the unlocked state. During the process of the first locking lever 215 moving the locking member 211 from the fourth stopping position to the third stopping position, the locking member 211 slides towards the first axial elongated hole 2160 under the action of the tension spring 214 until the fixing pin 225 is located in the first notch 2110, thereby making the power control lever 207 in the locked state.

[0163] Further preferably, both sides of the first notch 2110 are provided with rounded corners; this arrangement facilitates the entry of the fixing pin 225 into the first notch 2110.

[0164] It is worth noting that the main function of the locking mechanism is to lock the stationary go-kart. At this time, the balance car 400 is in a horizontal state, and the corresponding fixing pin 225 is also located in a specific position in the first axial elongated hole 2160. At this time, the fixing pin 225 can be locked by the locking member 211.

[0165] Furthermore, considering installation and manufacturing errors, the exact position of the fixing pin 225 when the go-kart is locked cannot be precisely determined. Therefore, in this embodiment, the locking cover 212 has multiple mounting positions on the mounting base 216. Specifically, a fine-tuning screw 226 and at least one bolt assembly are also provided. The mounting base 216 has a second axial elongated hole 2161 parallel to the first axial elongated hole 2160. The fine-tuning screw 226 is mounted on the side of the mounting base 216. Rotating the fine-tuning screw 226 allows the locking cover 212 to move along the second axial elongated hole 2161. When it moves to a position that can cooperate with the fixing pin 225, the locking cover 212 is fixed to the mounting base 216 by the bolt assembly.

[0166] In this embodiment, the steering wheel 204 is also provided with a horizontal through hole, and a third link 217, a fourth link 218 and a fifth link 219 are also provided. The third link 217 is rotatably mounted on the steering wheel 204. The cable 213 passes through the horizontal through hole and is connected to the outer end of the third link 217. The inner end of the third link 217 is hinged to one end of the fourth link 218. The other end of the fourth link 218 is hinged to one end of the fifth link 219. The other end of the fifth link 219 is rotatably mounted on the steering wheel 204. The first locking rod 215 is mounted on the fourth link 218 and the fifth link 219 and is located at the hinge of the fourth link 218 and the fifth link 219.

[0167] like Figure 16 As shown, the go-kart is currently in the unlocked state. Due to the action of the tension spring 214, the cable 213 exerts a horizontal force to the right on the outer end of the third link 217, causing the third link 217 to tend to rotate clockwise, which in turn causes the fourth link 218 to tend to rotate clockwise. However, the angle of the fifth link 219 prevents the fourth link 218 from rotating clockwise, thus preventing the third link 217 from rotating clockwise. This allows the first locking lever 215 to be in the third stopping position and keeps the go-kart in the unlocked state.

[0168] like Figure 17 As shown, the go-kart is in a locked state at this time. At this time, there is no force on the third link 217, that is, the first locking lever 215 can be in the third stop position and keep the go-kart in a locked state.

[0169] A second implementation of the locking mechanism prevents the assembly mechanism 100 from swinging back and forth, thereby locking the steering wheel 204 assembly and the operating connection assembly. Figure 12 and Figure 13 As shown, its specific structure includes two mounting brackets 220 fixedly mounted on the main body of the vehicle frame; each of the two mounting brackets 220 is provided with a first elongated hole 2200;

[0170] And locking rods 221 that are movable within the two first elongated holes 2200 on the left and right sides;

[0171] And a shift fork 222 rotatably mounted on two mounting brackets 220 on the left and right sides, the shift fork 222 being hinged to the power control linkage 210, the rear half of the shift fork 222 being movably connected to the assembly mechanism 100; the shift fork 222 is provided with a second notch 2220, and when the go-kart is stationary, the second notch 2220 is parallel to the first elongated hole 2200;

[0172] And a second locking lever 223 is movably mounted on the left and right mounting brackets 220. The second locking lever 223 causes the locking lever 221 to have a fifth stop position and a sixth stop position. During the process of the second locking lever 223 driving the locking lever 221 to move from the fifth stop position to the sixth stop position, the second locking lever 223 drives the locking lever 221 to move within the first elongated hole 2200 to move out of the second notch 2220, thereby making the go-kart unlocked. During the process of the second locking lever 223 driving the locking lever 221 to move from the sixth stop position to the fifth stop position, the second locking lever 223 drives the locking lever 221 to move within the first elongated hole 2200 to move into the second notch 2220, thereby making the go-kart locked.

[0173] Preferably, the assembly mechanism 100 includes a first connecting rod 118, which is fixedly connected to the left assembly frame 105 and the right assembly frame 106. The rear half of the shift fork 222 has a second elongated hole 2221 through which the first connecting rod 118 passes. More preferably, the first connecting rod 118 is a U-shaped rod, with its two ends fixedly connected to the left assembly frame 105 and the right assembly frame 106 respectively. The middle part of the first connecting rod 118 is located in front of the left assembly frame 105 and the right assembly frame 106, and passes through the second elongated hole 2221. This configuration allows the assembly mechanism 100 to swing back and forth with less force.

[0174] Preferably, the shift fork 222 includes a first connecting plate and a second connecting plate that are perpendicular to each other and integrally formed. The connection between the first and second connecting plates is rotatably mounted on two left and right mounting brackets 220 via a pivot. The second elongated hole 2221 is located on the first connecting plate, and the second notch 2220 is located at the top of the second connecting plate. The power control linkage 210 is hinged to the bottom end of the second connecting plate. This configuration makes operation more effortless and direct, and lowers the height of the seat 502, resulting in a more stable ride.

[0175] Preferably, a pusher 224 is also provided, which is fixedly installed on the second locking rod 223 and located between the left and right mounting brackets 220. The pusher 224 is provided with a third elongated hole, through which the locking rod 221 passes. Thus, rotating the second locking rod 223 can drive the locking rod 221 to move within the first elongated hole 2200.

[0176] Further preferably, the second locking rod 223 is an L-shaped rod, including a second connecting rod and a third connecting rod that are perpendicular to each other and integrally formed. The second connecting rod is horizontally and rotatably mounted on the left and right mounting brackets 220. The second connecting rod is located in front of the locking rod 221. The pushing member 224 is fixedly mounted on the second connecting rod. The third connecting rod is located on the outside of the left and right mounting brackets 220.

[0177] When the second locking lever 223 is in the sixth stopping position, the locking lever 221 is at the top of the first elongated hole 2200, and the third connecting lever is horizontal; thus, the third connecting lever has a downward tendency, which in turn makes the locking lever 221 have an upward tendency, and the first elongated hole 2200 simultaneously restricts the upward movement of the locking lever 221, thereby enabling the go-kart to maintain the unlocked state.

[0178] When the second locking lever 223 is in the fifth stop position, the locking lever 221 is located at the bottom end of the first elongated hole 2200, and the third connecting rod is vertical; in this way, the go-kart can maintain the locked state.

[0179] The specific control method for the go-kart in this embodiment is as follows:

[0180] When the steering wheel 204 is pushed forward, the steering linkage 205 swings forward, thereby causing the assembly mechanism 100 to tilt and deflect forward, giving the go-kart forward speed. The greater the forward push of the steering wheel 204, the greater the forward speed of the go-kart.

[0181] When the steering wheel 204 is pulled backward, the steering linkage 205 swings backward, thereby causing the assembly mechanism 100 to tilt and deflect backward, giving the go-kart a backward speed. The greater the backward pull of the steering wheel 204, the greater the backward speed of the go-kart.

[0182] It is worth noting that, such as Figure 13-15 The control structure in this embodiment can also be used in a hand-controlled go-kart with the left turning shaft 103 and the right turning shaft 104 built in; wherein, the left turning shaft 103 and the right turning shaft 104 being built in means that the left turning shaft 103 and the right turning shaft 104 are located inside the left wheel and the right wheel of the balance vehicle.

[0183] The locking structure in this embodiment can also be used in the foot-controlled go-kart in Embodiment 1.
