[0030] like Figures 1-5 As shown, an embodiment of this utility model provides a riding device, including a frame 100 and a bicycle 200. The bicycle 200 includes a frame 210, which is disposed inside the frame 100. The frame 210 includes a bottom bracket 211 and a rear fork 212. At least two fixing components 300 are spaced apart along the length direction inside the frame 100, and the fixing components 300 are fixedly connected to the opposite sides of the bottom bracket 211 and the rear fork 212, respectively. A roller 400 is provided at the bottom of the frame 100.

[0031] In this embodiment, the frame 100 is made of metal tubing, providing sufficient strength to stabilize the bicycle 200. Rollers 400 are installed at the bottom of each corner of the frame 100. The fixing components 300 are fixedly connected to the opposite sides of the bottom bracket 211 and rear fork 212 of the frame 210, respectively; that is, each fixing point uses a clamping and fixing method from opposite sides. This design of fixing from opposite sides forms a stable support structure, effectively preventing the bicycle 200 from swaying laterally or tipping over during riding.

[0032] Specifically, the fixing components 300 are spaced apart along the length of the frame 100, and include at least two sets of fixing components 300: one set for connecting the bottom bracket 211 of the bicycle 200, and the other set for connecting the rear fork 212 of the bicycle 200. The fixing component 300 for fixing the bottom bracket 211 includes support structures extending from the left and right sides of the frame 100 and fixedly connected to the left and right sides of the bottom bracket 211, respectively; similarly, the fixing component 300 for fixing the rear fork 212 also includes support structures extending from the left and right sides of the frame 100 and fixedly connected to the left and right sides of the rear fork 212, respectively. This fixing method forms a stable support, enabling the bicycle 200 to remain stable on the riding device and preventing lateral tilting.

[0033] When the riding device is in use, the rollers 400 at the bottom of the frame 100 and the wheels of the bicycle 200 are both in a rolling state. The main function of the frame 100 is to prevent the bicycle 200 from tilting during riding through the fixing component 300, rather than to completely bear the weight of the bicycle 200. The rollers 400 are designed to allow external vehicles or manual pulling of the frame 100 to propel the bicycle 200 forward, thus simulating the effect of the bicycle 200 moving forward in real life.

[0034] This design solves the problems of traditional solutions that rely on stunt doubles or post-production special effects, resulting in high costs and unrealistic effects. This embodiment, through the combined design of the frame 100 and the bicycle 200, particularly the use of fixing components 300 that secure the center axle 211 and rear fork 212 from opposite sides, and the cooperation of bottom rollers 400, effectively solves the problems of existing technologies such as incompatibility with tandem bicycles, lack of stability, and inability to realistically represent forward movement.

[0035] With fixed connections on both sides, this riding device ensures that even actors who cannot ride can safely and stably simulate real riding scenes. When the actor sits on the bicycle 200 and is pulled by an external vehicle or manually, the wheels of the bicycle 200 and the rollers 400 of the frame 100 roll simultaneously, achieving a realistic feeling of forward movement. The fixed connections on both sides ensure stability and safety throughout the process, significantly improving the efficiency and effect of film and television shooting.

[0036] In one embodiment, the frame 100 includes two horizontal bars 110 arranged opposite each other, and multiple connecting rods 120 are spaced apart between the horizontal bars 110 along the length direction. The connecting rods 120 and the horizontal bars 110 together form multiple accommodating spaces 130, which are used to accommodate the wheels and pedals of the bicycle 200.

[0037] In this embodiment, two crossbars 110 are arranged in parallel. The crossbars 110 are made of high-strength metal material and have sufficient strength. The crossbars 110 are connected by multiple connecting rods 120, which are arranged perpendicular to the crossbars 110 and spaced apart along the length of the crossbars 110. The crossbars 110 and the connecting rods 120 are fixed by welding or bolting to ensure a firm connection.

[0038] The connecting rod 120 and the crossbar 110 together form multiple accommodating spaces 130. These accommodating spaces 130 are designed to accommodate both the wheels and pedals of the bicycle 200, providing the actor with a natural riding environment. The wheels and pedals can rotate freely within their respective accommodating spaces 130, while the frame 100 is fixedly connected to the bicycle frame 210 of the bicycle 200 via a fixing component 300 to prevent the bicycle 200 from tipping over.

[0039] In actual use, when the actor pedals the bicycle 200, the wheels and pedals rotate in their respective or the same accommodating space 130, while the rollers 400 at the bottom of the frame 100 also roll at the same time, enabling the entire riding device to move forward, thereby achieving a realistic riding effect.

[0040] The structural design of this frame 100 solves the problem of existing technologies being unable to adapt to tandem bicycles. By rationally designing the length of the crossbar 110 and the position of the connecting rod 120, it can adapt to tandem bicycles of different models and sizes, improving the versatility of the riding device. At the same time, the design of multiple accommodating spaces 130 ensures the free rotation of each moving part of the bicycle 200. Combined with the rollers 400 at the bottom of the frame 100, it realizes the realistic forward movement function of the riding device, significantly enhancing the realism and effect of film and television shooting.

[0041] In addition, the frame structure formed by the crossbar 110 and the connecting rod 120 provides good stability, preventing the bicycle 200 from swaying or tipping over during riding, ensuring the safety of the actors, and also ensuring the smooth progress of the filming process.

[0042] In one embodiment, the crossbar 110 includes an outer tube portion 111, an inner tube portion 112, and a locking mechanism. The inner tube portion 112 is slidably disposed within the outer tube portion 111, and the locking mechanism is used to lock the inner tube portion 112 and the outer tube portion 111 in a predetermined position.

[0043] In this embodiment, the crossbar 110 adopts a telescopic structure design, and the outer tube portion 111 and the inner tube portion 112 can slide relative to each other. By adjusting the extension length of the inner tube portion 112 in the outer tube portion 111, the total length of the crossbar 110 can be adjusted. The locking mechanism is used to fix the inner tube portion 112 and the outer tube portion 111 in the desired position, thereby determining the length of the crossbar 110.

[0044] By adjusting the length of the crossbar 110, the size of the accommodating space 130 also changes, accommodating the wheel spacing of different models of tandem or multi-person bicycles 200. For longer multi-person bicycles 200, the crossbar 110 can be adjusted to its maximum length; for standard tandem bicycles, the crossbar 110 can be adjusted to a medium length; and for smaller tandem bicycles, the crossbar 110 can be adjusted to a shorter length.

[0045] This adjustable design enhances the applicability of the riding device. Since different models and brands of tandem or multi-person bicycles 200 vary in wheel spacing, a fixed-length crossbar 110 may not be suitable for all types of bicycles 200. However, by employing a slidable inner tube portion 112 and outer tube portion 111, the riding device of this embodiment can be adjusted according to the specific size of the bicycle 200, ensuring that the wheels of the bicycle 200 are precisely positioned within the accommodating space 130, achieving optimal fixation and riding experience.

[0046] In addition, the adjustable length design of the crossbar 110 facilitates the storage and transportation of the riding device. When not in use, the inner tube 112 can be completely or partially slid into the outer tube 111, reducing the overall size of the device and making it convenient for storage and carrying, especially suitable for frequent movement and location changes during outdoor shooting.

[0047] In one specific embodiment, taking a crossbar 110 as an example, it includes two outer tube portions 111 arranged opposite to each other, and an inner tube portion 112 is arranged between the two outer tube portions 111. The connecting rod 120 can be connected to the outer tube portions 111 by means of bolts or other fixing methods to avoid hindering the expansion and contraction of the inner tube portion 112 relative to the outer tube portions 111.

[0048] In one embodiment, the locking mechanism includes a plurality of positioning holes 113 provided on the outer tube portion 111 and the inner tube portion 112, and a locking bolt 114. The locking bolt 114 passes through the positioning holes 113 that communicate on the outer tube portion 111 and the inner tube portion 112 to fix the inner tube portion 112 and the outer tube portion 111 in a predetermined position.

[0049] In this embodiment, the crossbar 110 is provided with a plurality of positioning holes 113, and the inner tube portion 112 and the outer tube portion 111 are correspondingly provided with positioning holes 113. By passing the locking bolt 114 through the selected positioning hole 113, the inner tube portion 112 and the outer tube portion 111 can be fixed in the required position, thereby determining the length of the crossbar 110.

[0050] In practical use, first, loosen the locking bolt 114; then, adjust the position of the inner tube 112 within the outer tube 111 according to the wheel spacing of the bicycle 200; finally, pass the locking bolt 114 through the appropriate positioning hole 113 and tighten it to fix the length of the crossbar 110. The entire adjustment process does not require professional tools and can be quickly completed on-site, greatly improving work efficiency.

[0051] Multiple positioning holes 113 are provided along the length of the outer tube portion 111 and the inner tube portion 112, providing a variety of length options to allow the riding device to adapt to the size requirements of different bicycle models 200. The locking bolt 114 can be a combination of a standard bolt and nut for easy and quick installation and removal.

[0052] When the locking bolt 114 passes through the positioning hole 113 connecting the outer tube part 111 and the inner tube part 112 and is tightened, the inner tube part 112 and the outer tube part 111 are firmly locked together, ensuring that the crossbar 110 will not change length during use, thus guaranteeing the stability and safety of the entire riding device.

[0053] With the design of this positioning hole 113 and locking bolt 114, the riding device can adapt to the size requirements of different bicycles 200, while ensuring the ease of adjustment and the safety of use.

[0054] In other embodiments, the crossbar 110 includes a plurality of crossbar segments 115 and connectors 116, each of the two ends of the crossbar segment 115 having a mating structure, and the connectors 116 being used to detachably connect the mating structures of adjacent crossbar segments 115.

[0055] In this embodiment, the crossbar 110 adopts a modular design, including multiple standard-length crossbar segments 115 and connectors 116. Each crossbar segment 115 has threaded interfaces at both ends for mating, allowing for secure connection via the connectors 116. The connectors 116 use bolts to firmly connect adjacent crossbar segments 115, ensuring they do not loosen during use, and also allowing for disassembly by removing the bolts when necessary. The riding device can be assembled using different numbers of crossbar segments 115 as needed. By increasing or decreasing the number of crossbar segments 115, the length of the accommodating space 130 varies, thereby adapting to the wheel spacing requirements of different types of bicycles 200.

[0056] In one embodiment, the fixing component 300 includes two first support rods 310 spaced apart along the width direction of the frame 100. The bottom end of the first support rod 310 is fixedly connected to the frame 100, and the top end is fixedly connected to the opposite sides of the central axle 211 and the rear fork 212 of the frame 210, respectively.

[0057] In this embodiment, each first support rod 310 is inclined, with its bottom end fixed to the frame 100 and its top end fixedly connected to the corresponding component (bottom bracket 211 or rear fork 212) of the bicycle 200. The two first support rods 310 are distributed along the width direction of the frame 100, forming a support structure similar to the shape of the number eight. This design increases the stability and strength of the support.

[0058] The first support rod 310 is made of a sturdy and durable metal material, with sufficient strength to withstand the weight of the bicycle 200 and the rider, as well as various stresses generated during exercise. The length and tilt angle of the first support rod 310 are designed according to the height and width of the bicycle frame 210, ensuring that the bicycle 200 can be effectively secured and preventing it from tilting or wobbling during use.

[0059] For the fixing assembly 300 that fixes the bottom bracket 211, two first support rods 310 extend obliquely upwards from the left and right sides of the frame 100, respectively, and their top ends are fixedly connected to the opposite sides of the bottom bracket 211. Similarly, for the fixing assembly 300 that fixes the rear fork 212, two first support rods 310 also extend obliquely upwards from the left and right sides of the frame 100, and their top ends are fixedly connected to the opposite sides of the rear fork 212. Here, the fixed connection is achieved by connecting the threaded holes at the top of the first support rods 310 with the threaded holes on the bottom bracket 211 and the rear fork 212, and then tightening them with bolts or other fasteners.

[0060] This design, by using inclined first support rods 310 on opposite sides to form a triangular stabilizing structure, enables the bicycle 200 to maintain balance during riding and effectively resists possible swaying and tilting from all directions.

[0061] In one embodiment, the bottom end of the first support rod 310 is provided with a plurality of first fixing holes 311 along the width direction of the frame 100, and the top surface of the frame 100 is provided with a second fixing hole (not shown in the figure) along the width direction. A fixing screw (not shown in the figure) passes through the first fixing hole 311 and the second fixing hole.

[0062] In this embodiment, the bottom end of the first support rod 310 is designed to be flat, and a plurality of first fixing holes 311 are provided along the width direction of the frame 100. These first fixing holes 311 are arranged in a straight line, providing multiple possible fixing positions. The top surface of the frame 100 (crossbar 110) is also provided with corresponding second fixing holes along the width direction, and these second fixing holes correspond to the first fixing holes 311.

[0063] The fixing screw is used to connect the first support rod 310 and the frame 100. Specifically, the fixing screw is passed through the selected first fixing hole 311 and the second fixing hole, and then tightened with a nut to achieve a firm connection.

[0064] This design with multiple first fixing holes 311 provides flexibility in the installation position of the first support rod 310, allowing for the selection of a suitable fixing position based on the size requirements of different bicycle models 200. For example, for a wider bicycle frame 200, the first fixing hole 311 located on the outer side can be selected; while for a narrower bicycle frame 200, the first fixing hole 311 located on the inner side can be selected.

[0065] By adjusting the fixing position of the first support rod 310 on the frame 100, it can be adapted to bicycles 200 of different widths and models, improving the versatility and adaptability of the riding device. At the same time, the selection of multiple fixing positions also allows the support structure to be optimized for a specific bicycle 200, providing the best support effect.

[0066] This adjustable mounting system enhances the adaptability of the riding device, enabling it to better accommodate different types of tandem bicycles and providing more flexible and practical support for film and television shooting.

[0067] In one embodiment, at least two fixing components 300 include a first fixing component, which includes a main body portion 320, a U-shaped buckle 321, and a locking member 322. The main body portion is fixed to the frame 100, the U-shaped buckle 321 is disposed in the middle of the main body portion, the U-shaped buckle 321 has an opening portion for receiving the central shaft 211, and the locking member 322 is detachably connected to both ends of the U-shaped buckle 321 for locking the central shaft 211 in the U-shaped buckle 321.

[0068] In this embodiment, the first fixing component is disposed at the top of the frame 100 for fixing the central axle 211 of the bicycle 200. The U-shaped buckle 321 in the middle of the first fixing component adopts a U-shaped component design, which can surround and fix the central axle 211 from below.

[0069] The opening of the U-shaped component is designed to accommodate the bottom bracket 211 of the bicycle 200, while the bottom of the U-shaped component is connected to the main body of the first fixing assembly. The inner side of the U-shaped component may be provided with an anti-slip pad layer (not shown in the figure) to increase friction and protect the surface of the bottom bracket 211 from scratches.

[0070] Locking element 322 is used to securely connect the U-shaped component to the central shaft 211. Locking element 322 can be a combination of screws and nuts. Locking element 322 passes through threaded holes at both ends of the U-shaped component, and by tightening, the U-shaped component tightly surrounds the central shaft 211, achieving a stable connection.

[0071] The advantage of this U-shaped buckle 321 design is that the installation and disassembly process is simple and quick. During installation, simply align the opening of the U-shaped component with the central axis 211, and then secure it using the locking element 322; during disassembly, simply release the locking element 322 to release the U-shaped component. This design greatly improves work efficiency and is particularly suitable for situations requiring rapid device changes or adjustments on set.

[0072] In one embodiment, at least two fixing components 300 further include a second fixing component, which includes two second support rods 331. The bottom ends of the two second support rods 331 are fixed to the frame 100, and the top ends are fixedly connected to the left and right sides of the rear fork 212, respectively.

[0073] In this embodiment, the second fixing component is disposed at the top of the frame 100, behind the first fixing component, and is used to fix the rear fork 212 of the bicycle 200. The main structure of the second fixing component is two second support rods 331, which are distributed at intervals along the width direction of the frame 100 and are fixedly connected to the left and right sides of the rear fork 212 respectively.

[0074] Specifically, the second support rod 331 is inclined, with its bottom end fixed to the frame 100 and its top end fixedly connected to the left and right sides of the rear fork 212 respectively. The two second support rods 331 form a support structure similar to the figure eight, which increases the stability and strength of the support and can effectively prevent the bicycle 200 from swaying or tilting during use.

[0075] The second fixing component works in conjunction with the first fixing component to ensure the stability of the bicycle 200 on the riding device. The first fixing component fixes the bottom bracket 211 with a U-shaped buckle 321, while the second fixing component fixes the rear fork 212 with two second support rods 331. This two-point fixing method ensures that the bicycle 200 remains stable during riding and does not wobble or shift.

[0076] This design solves the problem of unstable fixation in existing tandem bicycles. Because tandem bicycles are relatively long, fixing only the bottom bracket 211 may cause the rear to wobble. By adding a second fixing component to secure the rear fork 212, the entire bicycle 200 is effectively supported, greatly improving the stability and safety of the riding process.

[0077] In practical applications, this two-point fixing method is particularly suitable for the fixing needs of tandem or multi-person bicycles 200. The combination of the first and second fixing components allows for adaptation to various sizes and models of bicycles 200, improving the versatility and practicality of the riding device.

[0078] In one embodiment, a pull rod 500 is provided at the front end of the frame 100, and a universal joint 510 is provided between the pull rod 500 and the frame 100.

[0079] In this embodiment, the pull rod 500 is installed at the front end of the frame 100 and is used to pull the entire riding device forward. The top of the pull rod 500 is equipped with a non-slip handle (not shown in the attached diagram) for easy gripping and application of force by the operator. The length of the pull rod 500 is moderate, ensuring that the operator can maintain an appropriate distance when pulling, without interfering with the shooting footage.

[0080] The tie rod 500 is connected to the frame 100 via a universal joint 510. The universal joint 510 is a connecting device that allows for multi-directional rotation, enabling a certain degree of rotational freedom between the tie rod 500 and the frame 100, thus making the traction direction more flexible.

[0081] In practical applications, the combined use of lever 500 and universal joint 510 allows the riding device to flexibly change its direction of travel according to shooting needs, simulating various riding scenarios such as straight riding, turning, and detouring, greatly enriching shooting possibilities. At the same time, since lever 500 is located at the front end of frame 100, the point of application of traction force is more reasonable, ensuring the stability and balance of the entire riding device during movement.

[0082] In this embodiment, the front end of the frame 100 refers to the side facing the forward direction of the riding device, which is also the end corresponding to the front wheel of the bicycle 200. The pull rod 500 is installed on this front end of the frame 100, specifically at the center of the front end of the frame 100, roughly aligned with the front wheel of the bicycle 200, to facilitate linear traction and balanced force distribution.

[0083] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
