Description

Technical Field

[0001] This application belongs to the field of recreational vehicle technology, and more specifically, relates to a lying-down running-assisted drift vehicle. Background Technology

[0002] A drift car is a common recreational vehicle, typically with three or four wheels. The front wheels are active steering wheels, while the rear wheels are swivel wheels. When in use, the operator drives the drift car forward. Once the car reaches a certain speed, the operator controls the front wheels to steer. Because the rear wheels are swivel wheels, the car will then drift and perform a fishtail maneuver, achieving a certain entertainment effect.

[0003] Currently, drift cars are mainly divided into two types: one driven by an electric motor and the other driven by foot pedals. Drift cars driven by electric motors are more expensive, while drift cars driven by foot pedals are cheaper, but driving the vehicle by foot pedals still requires a certain learning curve, especially for children. If they are not skilled, their feet may get stuck on the pedals, posing a safety risk. In addition, the operator's sense of speed is not as intuitive. Utility Model Content

[0004] In view of this, this application provides a prone-mounted running-assisted drift car to solve the technical problems existing in the prior art, which require a certain learning cost to drive the vehicle by pedals and the operator's perception of vehicle speed is not intuitive.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: On the one hand, a prone-mounted, assisted drift vehicle is provided, including: Frame; An active steering wheel is located at the front of the vehicle frame; Two follow-up steering wheels are located on both sides of the rear of the vehicle frame; The support section, located on the frame, is designed to allow the operator to lean forward, and a rearward support space is provided to facilitate the operator's leg movement.

[0006] In some embodiments, the rear portion of the frame includes two rearwardly extending rear control arms, each of which is provided with a follow-up steering wheel at its end, and the booster space is located between the two rear control arms.

[0007] In some embodiments, each of the two rear arms is provided with a support portion adapted to support the legs or feet of the operator in a prone position.

[0008] In some embodiments, the support portion is connected to the rear support arm via an adjustment structure for adjusting the front-rear position and / or height position of the support portion.

[0009] In some embodiments, the support extends into the booster space.

[0010] In some embodiments, the support is a tray, and the surface of the tray is in contact with the front of the lower leg of the operator who is lying face down on the support.

[0011] In some embodiments, in the vertical direction, the control portion of the active steering wheel is not higher than the portion of the support portion that supports the chest.

[0012] In some embodiments, the frame is an arch shape with a central upward convexity in the front-rear direction; a folding mechanism is provided between the front and rear of the frame, and the front and rear of the frame can be folded by compressing the inner space of the frame through the folding mechanism.

[0013] In some embodiments, the frame is provided with a storage basket, and in the longitudinal direction, the opening of the storage basket is located between the control part of the active steering wheel and the support part.

[0014] In some embodiments, the portion of the frame located between the active steering wheel and the support includes two front control arms, which are spaced apart along the width of the frame, and the storage basket is located between the two front control arms.

[0015] The beneficial effects of the prone running-assisted drift car provided in this application embodiment are as follows: Compared with the prior art, the prone running-assisted drift car in this application embodiment abandons the traditional straddle-riding method of drift cars, and instead adopts a forward-leaning riding method on the support, and provides the operator's legs with propulsion space, so that the operator can push the prone running-assisted drift car by walking or running, further reducing the learning cost, making it easier to control the speed, more intuitive to feel, and easier to use.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", 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 application 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 application.

[0022] Furthermore, in the description of this application, "multiple" and "several" mean two or more, unless otherwise explicitly defined; "front" refers to the direction in which the prone running-assisted drift car is normally moving, "rear" refers to the opposite direction of "front", and "sides" refers to both sides in the width direction of the prone running-assisted drift car, unless otherwise explicitly defined.

[0023] It is worth noting that because prone-assisted drift cars are inherently dangerous, users should be mindful of the circumstances in which they are used and comply with relevant laws and regulations to avoid causing harm to themselves or others. Children should generally be accompanied by a guardian when using them.

[0024] Please refer to the following: Figures 1 to 4The following describes the prone-type running-assisted drift vehicle provided in the embodiments of this application. A prone-type running-assisted drift vehicle includes: Frame; The active steering wheel is located at the front of the chassis. Two follow-up steering wheels are located on both sides of the rear of the frame; The support section, located on the frame, is designed to allow the operator to lean forward, while the rear provides a support space for the operator's legs to move.

[0025] Compared with the prior art, the prone running-assisted drift car of this application embodiment abandons the traditional straddle-riding method of drift cars and instead adopts a forward-leaning riding method on the support, and provides the operator's legs with propulsion space, so that the operator can push the prone running-assisted drift car by walking or running, further reducing the learning cost, making it easier to control the speed, more intuitive to feel, and easier to use.

[0026] In this embodiment, the frame serves as the main skeleton of the prone-running drift car. Its structural design ensures the overall stability of the prone-running drift car and provides mounting and positioning for other parts. In specific implementations, the frame structure can refer to the frame structure of traditional drift cars, or it can adopt the structure of other embodiments of this application.

[0027] In this embodiment, the active steering wheel can be controlled by the operator to change the direction of travel, causing the front of the prone running-assisted drift car to steer, thereby creating a tail-swing drift at the rear. The active steering wheel typically includes rollers, a steering column, and a control unit (usually handlebars or a steering wheel), and is rotatably mounted on the front of the frame, allowing the operator to control the steering. More specifically, the active steering wheel typically has one or two rollers, although more are not excluded. The position of the support and the active steering wheel on the frame is chosen so that when the operator is leaning forward on the support, their arms can just reach the handlebars or steering wheel of the active steering wheel.

[0028] In this embodiment, viewed from above, the follow-up steering wheel can freely deflect a certain angle to the left or right from directly behind. When the rear of the frame swings to the side due to inertia, the follow-up steering wheel can follow the steering, thus achieving the most basic unidirectional drift to the left or right. Typically, the steering angle of the follow-up steering wheel can be a 360° rotation, or it can be limited to a certain angle range, such as deflecting a certain angle to the left or right from directly behind, specifically 30°, 45°, etc. More specifically, the follow-up steering wheel can be a common omnidirectional wheel, or other roller structures capable of freely changing the direction of travel.

[0029] In this embodiment, the support section is used to support the operator who is leaning forward, allowing the operator to easily maintain a leaning position on the frame. It typically supports the operator's chest and / or abdomen, and may also provide some support to the shoulders and thighs. The support section can be a single component or a combination of multiple components supporting different parts of the operator. In practice, the support section is usually plate-shaped, providing large-area support for the operator. The support section may have some undulations to conform to the operator's body; for example, viewed from the front-back direction, the support surface (i.e., the top surface) of the support section is a concave arc shape, thus conforming to the operator's chest and / or abdomen and preventing the operator from slipping off the sides of the support section. More specifically, the support section can be a single plate-shaped piece, or it can be composed of multiple parallel strips, or multiple intersecting strips. The strips can be woven soft strips or injection-molded rigid strips.

[0030] Typically, this embodiment can be used in the following two ways: The first method: The operator can lie face down on the support, control the active steering wheel with their hands (usually the handlebars or steering wheel), and use their legs to push off the ground through the boost space to generate thrust. Once the vehicle reaches a certain speed, the operator lifts their legs off the ground and can then turn the vehicle by operating the active steering wheel, thus achieving a drift.

[0031] The second method involves the operator running within the booster space behind the support, holding and pushing the vehicle. As the vehicle gradually accelerates, the operator leans forward onto the support. Once the vehicle reaches a certain speed, the operator lifts their legs off the ground and can then steer by operating the active steering wheels, thus achieving a drift. This method requires ensuring the vehicle's direction doesn't deviate too much during the booster process, and it is relatively difficult to operate, requiring training before use.

[0032] It should be noted that the above are merely two possible specific usage methods of this embodiment, and it does not preclude the possibility that the product of this embodiment can be used in other ways.

[0033] Furthermore, those skilled in the art should understand that in this embodiment, the operator typically propels the vehicle by pushing off the ground with their legs in the booster space. However, it is not excluded that other drive devices may be installed on the prone running-assisted drift vehicle. These other drive devices can serve as auxiliary drives or as primary drives.

[0034] Please see Figures 1 to 4 As a specific embodiment of the prone running-assisted drift car provided in this application, the rear of the frame includes two rearwardly extending rear control arms, each rear control arm having a follow-up steering wheel at its end, and the boost space being located between the two rear control arms.

[0035] In this embodiment, the two rear support arms extend rearward from both sides of the boost space, making the boost space closer to the support part, and the follow-up steering wheel will not intrude into the boost space.

[0036] In practice, the frame extends rearward to form two rear control arms. The size of the space between the two control arms is typically designed to accommodate the operator's legs and facilitate running. The two rear control arms can be parallel and spaced apart, or they can be at an angle. The angled control arms can be arranged in a figure-eight shape or connected in a V-shape. Each control arm can be made from a single steel tube or composed of multiple parts.

[0037] Please see Figure 1 and 4 As a specific embodiment of the prone running-assisted drift vehicle provided in this application, each of the two rear support arms is provided with a support part, which is suitable for supporting the legs or feet of the operator in a prone position.

[0038] In this embodiment, a support part is provided on the rear support arm. When the operator leans forward on the support part and completes the push, the raised leg or foot can be placed on the support part.

[0039] In practical implementation, the support can be an independent component fixed to the rear outrigger, such as a rod-shaped or plate-shaped component installed on the support by means of bolting or welding; the support can also be processed from the rear outrigger, for example, the rear outrigger is made of steel pipe, and the steel pipe can be bent into a concave or convex shape for the operator's legs or feet to rest.

[0040] Please see Figures 1 to 4 As a specific embodiment of the prone running-assisted drift vehicle provided in this application, the support part and the rear support arm are connected by an adjustment structure, which is used to adjust the front-to-back position and / or height position of the support part.

[0041] In this embodiment, the front-to-back position and / or height position of the support can be adjusted according to the operator's body shape for ease of use. The adjustment structure can be used to adjust the front-to-back position or height position of the support, or to adjust both the front-to-back position and height position simultaneously.

[0042] In practical implementation, the rear outrigger can be a section of inclined steel pipe extending rearward and downward. The support unit is mounted on the inclined steel pipe via an adjustment mechanism, allowing the support unit to be adjusted along the inclined steel pipe, thus simultaneously adjusting its front-to-back and height positions. Alternatively, the rear outrigger can be a horizontal steel pipe, with the support unit mounted on it via an adjustment mechanism, allowing the support unit to be adjusted along the horizontal steel pipe, thus adjusting its front-to-back position. The rear outrigger can also be a vertical steel pipe, with the support unit mounted on it via an adjustment mechanism, allowing the support unit to be adjusted along the vertical steel pipe, thus adjusting its height position. The aforementioned inclined, horizontal, and vertical steel pipes can be the steel pipes constituting the rear outrigger, or they can be steel pipes specifically installed on the rear outrigger for adjustment.

[0043] The adjustment structure can be a common type of adjustment structure such as a pipe clamp or a sliding sleeve. For example, when using a pipe clamp, the support part can be adjusted along the steel pipe by loosening the pipe clamp. After adjustment, the screws are tightened to lock the pipe clamp. When using a sliding sleeve, a set screw or a pin is set on the sliding sleeve for locking. After the sliding sleeve is adjusted to the right position, the set screw is used to tighten the steel pipe or the pin is used to pass through the sliding sleeve and the steel pipe to achieve locking.

[0044] Please see Figure 1 and 4 As a specific embodiment of the prone running-assisted drift vehicle provided in this application, the support extends into the boost space (also known as the avoidance space).

[0045] In this embodiment, the support is closer to the clearance space, so that after the operator leans forward on the support and completes the push, his legs or feet can be easily placed on the support.

[0046] In practice, the support can be installed on the inside of the rear outrigger, thereby extending into the clearance space.

[0047] Please see Figure 1 and 4 As a specific embodiment of the prone running-assisted drift vehicle provided in this application, the support part is a tray, and the surface of the tray is in contact with the front of the lower leg of the operator who is lying prone on the support part.

[0048] In this embodiment, the support part adopts a tray, which can support the front of the operator's lower leg and distribute the pressure on the lower leg.

[0049] In practical implementation, the surface of the pallet can be designed based on the shape of the front side of the human lower leg. After the pallet is installed on the rear support arm, the angle of the pallet surface should be such that when the operator lies prone on the support, the front side of the lower leg can fit in close contact with the pallet surface.

[0050] Please see Figure 2 As a specific embodiment of the prone running-assisted drift car provided in this application, in the vertical direction, the control part of the active steering wheel is not higher than the part of the support part that supports the chest.

[0051] In this embodiment, the operator can more easily operate the control unit of the active steering wheel after lying prone on the support.

[0052] In specific implementations, the support unit can support the operator's chest as well as the operator's abdomen, shoulders, and other areas. In this case, the control part of the active steering wheel is not higher than the part of the support unit that supports the chest. In some cases, when the operator leans forward on the support unit, the area of ​​the support unit corresponding to the operator's chest may be missing or hollowed out. In this case, the missing or hollowed-out area should be filled in. If the control part of the active steering wheel is not higher than the part of the support unit that supports the chest after the filling in, this situation still falls under the scope of this embodiment.

[0053] Please see Figures 1 to 4 As a specific embodiment of the prone running-assisted drift car provided in this application, the frame is an arch shape with a central upward convexity in the front-rear direction; a folding mechanism is provided between the front and rear of the frame, and the front and rear of the frame can be folded by compressing the inner space of the frame through the folding mechanism.

[0054] In this embodiment, the front and rear of the frame are arched when unfolded via the folding mechanism, allowing for normal use (e.g., Figure 2 When the front and rear of the frame are folded down via the folding mechanism, the internal space of the frame can be compressed (e.g., ...). Figure 3 This reduces the overall size of the prone-mounted running drift car, minimizing its space occupation and making it easier to carry and store.

[0055] In practice, the main body of the frame is an arched structure, while allowing for additional structures extending beyond the arch. The arch is not limited to a smooth curve; it can also be a zigzag arch with distinct bends, such as an inverted V or U shape. The support is mounted on the frame, typically at the top. It can be directly fixed to the top of the frame or secured using other intermediate structures. Generally, the active steering wheel is mounted at the front of the arch, and the follow-up steering wheel at the rear.

[0056] The division between the front and rear sections of the frame can be in front of the support section, behind the support section, or overlap with the support section; correspondingly, the folding mechanism on the frame can be in front of the support section, behind the support section, or overlap with the support section. When the folding mechanism overlaps with the support section, the support section can fold along with the front and rear sections of the frame, or it can remain folded.

[0057] More specifically, the folding mechanism can be based on existing bicycle folding mechanisms, which can lock the frame in both the unfolded and folded states. For example, the folding mechanism can be structured such that the front and rear of the frame are connected by a pivot, with positioning holes near the pivot on both sides. When the front and rear of the frame are unfolded, the positioning holes on the front and rear sides face each other, and locking pins can be inserted into these opposing positioning holes to lock the frame. When the front and rear of the frame are folded, another pair of positioning holes on the front and rear sides face each other, and locking pins can be inserted into these opposing positioning holes to lock the frame.

[0058] Please see Figures 2 to 4 As a specific embodiment of the prone running-assisted drift car provided in this application, the frame is equipped with a storage basket, and in the front-rear direction, the opening for taking out and putting in the storage basket is located between the control part and the support part of the active steering wheel.

[0059] In this embodiment, the space between the control part and the support part of the active steering wheel is fully utilized to set up the access port of the storage basket, making it convenient to retrieve the items in the storage basket.

[0060] In practical implementation, the lower part of the active steering wheel is a roller, and the upper part is the control unit (steering wheel or handlebars). The support unit is located behind the active steering wheel control unit, and there is a certain distance between the two. The access port is set in this space, which can make full use of this space and facilitate the retrieval of items in the storage basket. As an example, generally, the access port will not be higher than the support unit and the control unit; commonly, the access port will be lower than the lower of the support unit and the control unit.

[0061] The main part of the storage basket for storage can be set in any open position on the frame. For example, it can be set between the control part and the support part of the active steering wheel, or it can be set on one or both sides of the frame. When an arched frame is used, it can also extend into the arch space of the frame.

[0062] Please see Figures 1 to 4 As a specific embodiment of the prone running-assisted drift car provided in this application, the part of the frame between the active steering wheel and the support includes two front control arms, which are spaced apart along the width of the frame, and a storage basket is located between the two front control arms.

[0063] In this embodiment, the two front support arms are spaced apart to make room for the storage basket, ensuring the volume of the storage basket, while the two front support arms provide a certain degree of protection for the storage basket.

[0064] The part of the chassis located between the active steering wheel and the support is the part of the chassis between the location where the support is installed and the location where the active steering wheel is installed.

[0065] In practice, the front ends of the two front arms are connected to each other, forming an overall shape that approximates a V or U (e.g., ...). Figure 4 The two front control arms are angled downwards at their front ends and rotate to mount the steering column, which houses the active steering wheel. The rear ends of the two front control arms are angled upwards to connect to the support unit.

[0066] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
