Description

Technical Field

[0001] This utility model relates to the technical field of sports equipment, and in particular to a sports skateboard. Background Technology

[0002] Skateboarding, as a representative of extreme sports, is very popular among young people. Specifically, skateboarding uses the twisting of the body (waist, hips, etc.) and feet, as well as the swinging of the hands, to propel forward, achieving the purpose of fitness. Patent document CN221014450U discloses a swivel-wheel skateboard, which, through the arrangement of a first link, a second link, and a first elastic element between the front and rear pedals, enables the swivel-wheel skateboard to have good forward torque in active board mode. However, this swivel-wheel skateboard has a complex structure, high production costs, and a relatively large overall weight, making it inconvenient for daily carrying. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a sports skateboard that uses a combination of chain and coil spring. This not only provides users with greater forward torque but also simplifies the structure, facilitates subsequent manufacturing, and reduces weight, making it easier for people to carry around in daily life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sports skateboard includes: a set of omnidirectional wheels, a front pedal and a rear pedal spaced apart above the set of omnidirectional wheels, a first mounting tube on the lower end face of the front pedal, a second mounting tube on the lower end face of the rear pedal, a chain connecting the first mounting tube and the second mounting tube, a helical spring on the outside of the chain, one end of the helical spring being located on the first mounting tube, and the other end of the helical spring being located on the second mounting tube.

[0006] Furthermore, each end of the chain is connected to a mounting block, which is movably inserted into one end of the first mounting tube or the second mounting tube. Both the first mounting tube and the second mounting tube are provided with a first locking hole with the opening facing upwards. Each mounting block is provided with a second locking hole, and the first locking hole and the corresponding second locking hole are connected by a first pin.

[0007] Furthermore, the chain includes multiple outer chain plates, a second pin, and an inner chain plate arranged in the same direction. The outer chain plates are rotatably connected to the inner chain plates via the second pin, which extends vertically.

[0008] Furthermore, the mounting block is a third mounting tube, one end of which is inserted into the first mounting tube or the second mounting tube, and the chain is welded between the two third mounting tubes.

[0009] Furthermore, one end of the first mounting tube and the second mounting tube are tightly fitted with the inner wall of the helical spring, and the first pin abuts against a portion of the helical spring.

[0010] Furthermore, it also includes two pipe clamps, which are connected to the front pedal or the rear pedal by bolts, and the pipe clamps have cavities for clamping the first mounting pipe or the second mounting pipe.

[0011] Furthermore, the pipe clamp includes a U-shaped plate, with mounting plates connected to both sides of the U-shaped plate. The bolt is disposed on the mounting plate, and the U-shaped plate is provided with a limiting rod. The first mounting pipe and the second mounting pipe are provided with third locking holes, and the limiting rod is inserted into the corresponding third locking hole.

[0012] Furthermore, both the front pedal and the rear pedal include two oppositely arranged side surfaces, with an arc-shaped convex surface and an arc-shaped concave surface connecting the two side surfaces.

[0013] Furthermore, the caster assembly includes four casters arranged in a rectangular pattern, with two casters each on the front pedal and the rear pedal.

[0014] Compared with existing technologies, this utility model has the following beneficial effects:

[0015] 1. This utility model uses a combination of chain and helical spring, which simplifies the existing structure that uses connecting rod, facilitates subsequent manufacturing, and reduces weight, making it easier for people to carry in daily life.

[0016] 2. The helical spring of this utility model is set in the first mounting tube and the second mounting tube, thereby forming a structure similar to a lever arm, which is conducive to the front pedal and the rear pedal driving the helical spring to generate better swing deformation, thereby providing the user with greater forward torque.

[0017] 3. This utility model incorporates a chain inside the helical spring, which better matches the swing amplitude of the helical spring, thereby better coordinating the movement of the front and rear pedals. Attached Figure Description

[0027] See Figures 1 to 3 A sports skateboard includes: a set of omnidirectional wheels, a front pedal 100 and a rear pedal 200 spaced apart above the set of omnidirectional wheels, a first mounting tube 110 provided on the lower end surface of the front pedal 100, a second mounting tube 210 provided on the lower end surface of the rear pedal 200, a chain 300 connecting the first mounting tube 110 and the second mounting tube 210, a helical spring 400 provided on the outside of the chain 300, one end of the helical spring 400 being provided on the first mounting tube 110, and the other end of the helical spring 400 being provided on the second mounting tube 210.

[0028] The above-described sports skateboard, employing a chain 300 and a coil spring 400, simplifies existing linkage structures, facilitating subsequent manufacturing and reducing the overall weight of the product, making it easier for people to carry. The coil spring 400 is positioned within the first mounting tube 110 and the second mounting tube 210, forming a lever-like structure. This allows the front pedal 100 and rear pedal 200 to better drive the coil spring 400 to produce oscillating deformation, thereby providing greater forward torque for the user. Furthermore, by incorporating the chain 300 within the coil spring 400, the chain 300 can better match the oscillation amplitude of the coil spring 400, thus better coordinating the movement of the front pedal 100 and rear pedal 200.

[0029] In use, the user places both feet on the front pedal 100 and the rear pedal 200 respectively, and controls the swinging of the front pedal 100 or the rear pedal 200, or both, by twisting their body. This allows the skateboard to generate a forward torque through changes in angle, driving the omnidirectional wheels and enabling the skateboard to move forward in an S-shape. During the swinging of the front pedal 100 and the rear pedal 200, the coil spring 400 and the chain 300 generate corresponding swing amplitudes. The elastic force of the coil spring 400 drives the front pedal 100 or the rear pedal 200 to quickly return to its original position. This not only makes it easier for the user to swing the front pedal 100 or the rear pedal 200 individually, reducing the difficulty of operation, but also further increases the speed of the skateboard by increasing the swing frequency of the front pedal 100 or the rear pedal 200.

[0030] See Figures 1 to 3 Furthermore, each end of the chain 300 is connected to a mounting block 310. The mounting block 310 is movably inserted into one end of the first mounting tube 110 or the second mounting tube 210. Both the first mounting tube 110 and the second mounting tube 210 are provided with an upward-facing first locking hole 111, and each mounting block 310 is provided with a second locking hole 311. The first locking hole 111 and the corresponding second locking hole 311 are connected by a first pin 112. Specifically, by inserting the first pin 112 into the corresponding first locking hole 111 and second locking hole 311, the chain 300 can be detachably connected between the first mounting tube 110 and the second mounting tube 210, thereby simplifying the installation of the chain 300 and facilitating subsequent disassembly and replacement of the chain 300.

[0031] See Figures 1 to 3 Furthermore, the chain 300 includes multiple outer chain plates 301, a second pin 302, and an inner chain plate 303 arranged in the same direction. The outer chain plates 301 are rotatably connected to the inner chain plates 303 via the second pin 302, which extends vertically. Specifically, the multiple mutually rotatably connected outer chain plates 301 and inner chain plates 303 form multiple swingable links in the chain 300, which helps the chain 300 better match the swing deformation of the coil spring 400, thereby better coordinating the movement of the front pedal 100 or the rear pedal 200. The second pin 302 extends vertically, allowing the outer chain plates 301 and inner chain plates 303 to swing in the horizontal plane, thus better matching the swing of the front pedal 100 and the rear pedal 200.

[0032] See Figures 1 to 3 Furthermore, the mounting block 310 is a third mounting tube, one end of which is inserted into the first mounting tube 110 or the second mounting tube 210, and the chain 300 is welded between the two third mounting tubes. Specifically, the outer diameter of the third mounting tube is smaller than the inner diameter of the first mounting tube 110 and the second mounting tube 210, thereby facilitating the rotation of the third mounting tube so that the first locking hole 111 can be aligned with the corresponding second locking hole 311.

[0033] See Figures 1 to 3Furthermore, one end of the first mounting tube 110 and the second mounting tube 210 is tightly fitted with the inner wall of the coil spring 400, and the first pin 112 abuts against a portion of the coil spring 400. Specifically, during installation, the mounting block 310 at one end of the chain 300 is first inserted into the first mounting tube 110, then one end of the coil spring 400 is tightly fitted onto the outside of the first mounting tube 110, and finally the first pin 112 is used to lock into the corresponding first locking hole 111 and second locking hole 311. This facilitates the use of the first pin 112 to restrict the coil spring 400 from disengaging from the first mounting tube 110, thereby completing the engagement of the chain 300 and the coil spring 400 with the first mounting tube 110. Similarly, the mounting block 310 at the other end of the chain 300 is inserted into the second mounting tube 210, and one end of the coil spring 400 is tightly fitted onto the outside of the second mounting tube 210. Finally, another first pin 112 is used to complete the engagement between the second mounting tube 210 and the corresponding mounting block 310. With the above structure, the chain 300 and the coil spring 400 are detachably connected to the first mounting tube 110 and the second mounting tube 210. The overall installation is convenient and quick, which is beneficial for subsequent maintenance or replacement of the chain 300 or the coil spring 400.

[0034] See Figures 1 to 3 Furthermore, it also includes two pipe clamps 500, which are connected to the front pedal 100 or the rear pedal 200 via bolts 600. Each pipe clamp 500 has a cavity for clamping the first mounting pipe 110 or the second mounting pipe 210, thereby providing the mounting position for the first mounting pipe 110 or the second mounting pipe 210. It is understood that in some embodiments, the pipe clamp 500 can be replaced with a block. The block has a through hole through which the first mounting pipe 110 or the second mounting pipe 210 can pass. The block has a threaded hole in the vertical direction, and the threaded hole has a screw with a third locking hole at one end, thereby quickly fixing the first mounting pipe 110 or the second mounting pipe 210.

[0035] See Figures 1 to 3 Furthermore, the pipe clamp 500 includes a U-shaped plate 501, with mounting plates 502 connected to both sides of the U-shaped plate 501. Bolts 600 are mounted on the mounting plates 502. The U-shaped plate 501 is provided with limiting rods 503. The first mounting tube 110 and the second mounting tube 210 are provided with third locking holes, and the limiting rods 503 are inserted into the corresponding third locking holes. Specifically, during installation, the first mounting tube 110 and the second mounting tube 210 are placed inside the U-shaped plate 501, then the limiting rods 503 are inserted into the third locking holes, and finally the bolts 600 are mounted on the mounting plate 502 and the front pedal 100 or the rear pedal 200, thereby using the limiting rods 503 to restrict the detachment of the first mounting tube 110 or the second mounting tube 210.

[0036] See Figures 1 to 3Furthermore, both the front pedal 100 and the rear pedal 200 include two oppositely arranged sides, with an arc-shaped convex surface and an arc-shaped concave surface connecting the two sides, thereby facilitating a larger swing space between the front pedal 100 and the rear pedal 200.

[0037] See Figures 1 to 3 Furthermore, the swivel wheel 700 set includes four rectangularly distributed swivel wheels 700, with two swivel wheels 700 each on the front pedal 100 and the rear pedal 200. Specifically, compared to existing skateboards that only have two swivel wheels 700, the four swivel wheels 700 not only provide greater torque for skateboard movement but also improve the smoothness of skateboard movement, making it safer and more stable.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
