Description

Technical Field

[0001] The present invention relates to the technical field of land surfing skateboards, in particular to a skateboard easy-to-swing front bracket and a land surfing skateboard. Background Art

[0002] Land surfing skateboard, as the name suggests, is a skateboard that simulates surfing on the sea, or a surfing trainer, which allows surfers to glide infinitely on land, saying goodbye to the traditional skateboard that relies on pushing the ground with the feet, and relies on left and right tilt changes to move forward.

[0003] A land surfing skateboard primarily comprises a front wheel rotating bracket, a skateboard body, and a rear wheel bracket, with the front wheel rotating bracket and the rear wheel bracket being mounted at the front and rear ends of the skateboard body, respectively. The front wheel rotating bracket comprises a front support base, a front support bridge rod, and a front shock absorber soft boot assembly, with the front support bridge rod being rotatably connected to the front support base. The front shock absorber soft boot assembly is disposed between the front support base and the front support bridge rod, and the front shock absorber soft boot assembly abuts against the front support base and the front support bridge rod, respectively. The front support base is mounted at the front end of the skateboard body.

[0004] When the user swings his body, the front support bridge rod rotates left and right to achieve an S-shaped movement, simulating the effect of surfing on the sea. However, on the one hand, the user's swinging will cause the sliding body and the front support base to swing, causing the front support base to squeeze the front shock absorber soft cover assembly, causing the front shock absorber soft cover assembly to generate rotational resistance to the front support bridge rod, reducing the steering flexibility of the front support bridge rod. On the other hand, the friction between the front shock absorber soft cover assembly and the front support bridge rod and the front support base increases due to deformation. As the deformation of the front shock absorber soft cover assembly increases, the rotational resistance of the front support bridge rod also increases. According to the actual situation of the user, when the applied downward force is less than or equal to the maximum static friction force, the front support bridge rod can no longer rotate, thereby reducing the rotation angle of the support bridge rod. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a skateboard easy-to-swing front bracket and a land surfing skateboard with high rotation flexibility and increased rotation angle of the bracket bridge rod.

[0011] In one embodiment, a front gasket of each front shock-absorbing soft cover assembly is formed with a receiving groove, and a portion of the front shock-absorbing cover of each front shock-absorbing soft cover assembly is received in the corresponding receiving groove.

[0012] In one embodiment, the periphery of the front gasket of each front shock-absorbing soft cover assembly is arranged around the corresponding front shock-absorbing cover.

[0013] In one embodiment, the skateboard's easy-to-swing front bracket further includes a fastener, which is sleeved on the front mounting center column shaft, and the fastener also abuts against another front shock-absorbing soft cover assembly.

[0014] In one embodiment, the fastener is threadedly connected to the front mounting center column shaft.

[0017] In one embodiment, the rolling friction pressure-dividing intervention component also includes a first rotation limit plate, which is rotatably connected to one side of the restraining member, and the first rotation limit plate is also rollingly connected to each of the planar rolling members. The first rotation limit plate is also connected to the force-bearing end of the front shock-absorbing soft cover assembly, so that the force-bearing end of the front shock-absorbing soft cover assembly is connected to the planar rolling member through the first rotation limit plate.

[0018] In one embodiment, the rolling friction pressure-dividing intervention component also includes a second rotation limit plate, which is rotatably connected to one side of the restraint member, and the second rotation limit plate is also connected to the front support base so that the planar rolling member is connected to the front support base through the second rotation limit plate.

[0024] 1. When the board body swings, the front support base swings and squeezes the front shock absorber soft sleeve assembly. When the front shock absorber soft sleeve assembly is compressed to a certain extent, the front shock absorber soft sleeve assembly will push the flat rolling element to roll relative to at least one of the force-bearing end of the front shock absorber soft sleeve assembly and the front support base, thereby causing the front shock absorber soft sleeve assembly to rotate with the front bracket bridge rod while being compressed, thereby reducing the resistance to the rotation of the front bracket bridge rod, improving the steering flexibility of the front bracket bridge rod, and making sliding smoother.

[0025] 2. Since the front shock absorber soft sleeve assembly rotates with the front bracket bridge rod while being under pressure, the friction on the front shock absorber soft sleeve assembly is reduced, thereby increasing the service life of the front shock absorber soft sleeve assembly.

[0026] 3. Since the resistance to the rotation of the front bracket bridge rod is small, the maximum static friction force is small, which allows the user to drive the bracket bridge rod to rotate at a larger angle, that is, increases the rotation angle of the bracket bridge rod and makes sliding easier.

[0039] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] The present application provides a front bracket of a skateboard that is easy to swing, comprising a front support base, a front bracket bridge rod, a front shock-absorbing soft sleeve assembly and a front mounting center column shaft, the front mounting center column shaft being sequentially passed through the front support base, the front shock-absorbing soft sleeve assembly and the front bracket bridge rod, the front bracket bridge rod being further provided with a front center column support shaft rotatably connected to the front support base, the front bracket of the skateboard that is easy to swing also comprises a rolling friction pressure-dividing intervention assembly, the rolling friction pressure-dividing intervention assembly comprises: a restraining member and at least one planar rolling member, the restraining member being sleeved outside the planar rolling member, the planar rolling member being respectively connected to the force-bearing end of the front shock-absorbing soft sleeve assembly and the front support base, the planar rolling member being used to roll relative to the force-bearing end of the front shock-absorbing soft sleeve assembly and / or the front support base, the force-releasing end of the front shock-absorbing soft sleeve assembly being connected to the front bracket bridge rod.

[0043] The present application also provides a land surfing skateboard, including a skateboard body and a skateboard rear bracket. The land surfing skateboard also includes the above-mentioned skateboard easy-to-swing front bracket, the front support base is fixedly connected to the front end of the skateboard body, and the skateboard rear bracket is installed at the rear end of the board body.

[0044] In the above-mentioned easy-to-swing front bracket of the skateboard and the land surfing skateboard, when the board body swings, the front support base swings and squeezes the front shock-absorbing soft sleeve assembly. When the front shock-absorbing soft sleeve assembly is compressed to a certain extent, the front shock-absorbing soft sleeve assembly will push the flat rolling element to roll relative to at least one of the force-bearing end of the front shock-absorbing soft sleeve assembly and the front support base, thereby causing the front shock-absorbing soft sleeve assembly to rotate with the front bracket bridge rod while being compressed, reducing the resistance to the rotation of the front bracket bridge rod, improving the steering flexibility of the front bracket bridge rod, and making sliding smoother. Moreover, since the front shock-absorbing soft sleeve assembly rotates with the front bracket bridge rod while being compressed, the friction on the front shock-absorbing soft sleeve assembly is reduced, thereby increasing the service life of the front shock-absorbing soft sleeve assembly. In addition, since the resistance to the rotation of the front bracket bridge rod is small, the maximum static friction force is small, thereby allowing the user to drive the bracket bridge rod to rotate at a larger angle, that is, to increase the rotation angle of the bracket bridge rod, while making sliding easier.

[0045] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:

[0046] like Figure 1 and Figure 2 As shown, a land surfing skateboard 10 of an embodiment includes a skateboard body 100, a skateboard easy-to-swing front bracket 200 and a skateboard rear bracket 300, and the skateboard easy-to-swing front bracket 200 and the skateboard rear bracket 300 are respectively installed at the front and rear ends of the skateboard body 100.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the easy-to-swing front bracket 200 of the skateboard includes a front support base 210, a front bracket bridge rod 220, a front shock-absorbing soft cover assembly 230 and a front mounting center column shaft 240. The front mounting center column shaft 240 is sequentially arranged through the front support base 210, the front shock-absorbing soft cover assembly 230 and the front bracket bridge rod 220, that is, the front support base 210, the front shock-absorbing soft cover assembly 230 and the front bracket bridge rod 220 are all sleeved on the front mounting center column shaft 240, so that the front support base 210 and the front bracket bridge rod 220 are rotatably connected through the front mounting center column shaft 240. In addition, the front shock-absorbing soft cover assembly 230 is arranged between the front support base 210 and the front bracket bridge rod 220, so that the front shock-absorbing soft cover assembly 230 has a shock-absorbing effect. The front bracket bridge rod 220 is also provided with a front center column support shaft 221 rotatably connected to the front support base 210 , so that the front bracket bridge rod 220 has two rotatable connections with the front support base 210 to improve the rotation stability of the front bracket bridge rod 220 .

[0048] like Figure 4As shown, the skateboard's easy-to-swing front bracket 200 further includes a rolling friction pressure-dividing intervention component 250. The rolling friction pressure-dividing intervention component 250 includes a restraining member 251 and at least one planar rolling member (not shown). The restraining member 251 is sleeved outside the planar rolling member (not shown) to restrict the planar rolling member (not shown) from rolling within the restraining member 251. The planar rolling member (not shown) is respectively connected to the force-bearing end of the front shock-absorbing soft cover assembly 230 and the front support base 210. The planar rolling member (not shown) is used to roll relative to the force-bearing end of the front shock-absorbing soft cover assembly 230 and / or the front support base 210. The force-releasing end of the front shock-absorbing soft cover assembly 230 is connected to the front bracket bridge rod 220. In this embodiment, a planar rolling element (not shown) rolls relative to at least one of the force-bearing end of the front shock-absorbing soft cover assembly 230 and the front support base 210. When a user uses the land surfing skateboard 10, the user steps on the board 100 with both feet and swings the body left and right to slide the land surfing skateboard 10. It is understood that the planar rolling element (not shown) can be a cylindrical structure, a spherical structure, or other existing rolling structures.

[0049] The above-mentioned skateboard has an easy-to-swing front bracket 200. When the board body 100 swings, the front support base 210 swings and squeezes the front shock-absorbing soft cover assembly 230. When the front shock-absorbing soft cover assembly 230 is compressed to a certain extent, the front shock-absorbing soft cover assembly 230 will push the flat rolling element (not shown) to roll relative to at least one of the force-bearing end of the front shock-absorbing soft cover assembly 230 and the front support base 210, thereby causing the front shock-absorbing soft cover assembly 230 to rotate with the front bracket bridge rod 220 while being compressed, reducing the resistance to the rotation of the front bracket bridge rod 220, improving the steering flexibility of the front bracket bridge rod 220, and making the sliding smoother. Moreover, since the front shock-absorbing soft cover assembly 230 rotates with the front bracket bridge rod 220 while being compressed, the friction on the front shock-absorbing soft cover assembly 230 is reduced, thereby increasing the service life of the front shock-absorbing soft cover assembly 230. In addition, since the resistance to the rotation of the front support bridge rod 220 is small, the maximum static friction force is small, which allows the user to drive the support bridge rod to rotate at a larger angle, that is, increases the rotation angle of the support bridge rod and makes sliding easier.

[0050] like Figure 4 As shown, in one embodiment, a flat rolling element (not shown) is used to roll relative to the force-bearing end of the front shock-absorbing soft cover assembly 230 and the front support base 210 .

[0051] like Figure 4As shown, in one embodiment, there are two front shock-absorbing soft sleeve assemblies 230, both of which are sleeved on the front mounting center column shaft 240. The two front shock-absorbing soft sleeve assemblies 230 are respectively connected to opposite sides of the front support bridge rod 220, and one of the front shock-absorbing soft sleeve assemblies 230 is also connected to a flat rolling element (not shown). In this embodiment, the two front shock-absorbing soft sleeve assemblies 230 are arranged on opposite sides of the front support bridge rod 220, which improves the shock absorption effect of the land surfing skateboard 10, while increasing the swing amplitude of the front support base 210, thereby improving the rotational flexibility of the front support bridge rod 220.

[0052] like Figure 4 As shown, in one embodiment, each front shock absorber soft cover assembly 230 includes a front shock absorber cover 231 and a front gasket 232. The front shock absorber cover 231 of each front shock absorber soft cover assembly 230 is sleeved on the front mounting center column shaft 240. The front shock absorber covers 231 of the two front shock absorber soft cover assemblies 230 are respectively connected to the opposite sides of the front bracket bridge rod 220. The front gasket 232 of each front shock absorber soft cover assembly 230 is respectively connected to the side of the corresponding front shock absorber cover 231 away from the front bracket bridge rod 220. The front gasket 232 of one of the front shock absorber soft cover assemblies 230 is also connected to a plane rolling member (not shown). In this embodiment, the front gasket 232 of one of the front shock-absorbing soft cover assemblies 230 is connected to the flat rolling member (not shown), so that the front shock-absorbing soft cover assembly 230 and the flat rolling member (not shown) are in hard contact, thereby avoiding the situation where the force-bearing end of the front shock-absorbing soft cover assembly 230 is concave and hinders the rolling of the flat rolling member (not shown), that is, the flat rolling member (not shown) can roll smoothly, thereby ensuring that the flat rolling member (not shown) can play its role.

[0053] like Figure 4 As shown, in one embodiment, the front gasket 232 of each front shock-absorbing soft cover assembly 230 is formed with a receiving groove 2321, and part of the front shock-absorbing cover 231 of each front shock-absorbing soft cover assembly 230 is received in the corresponding receiving groove 2321, so that the front shock-absorbing cover 231 of each front shock-absorbing soft cover assembly 230 is limited in the corresponding receiving groove 2321, thereby improving the stability of the installation position of the front shock-absorbing cover 231.

[0054] like Figure 4 As shown, in one embodiment, the periphery of the front gasket 232 of each front shock-absorbing soft cover assembly 230 is arranged around the corresponding front shock-absorbing cover 231, so that the front shock-absorbing cover 231 of each front shock-absorbing soft cover assembly 230 is limited to deform at the corresponding position.

[0055] like Figure 4As shown, in one embodiment, the skateboard easy-to-swing front bracket 200 further includes a fastener 260 , which is sleeved on the front mounting center column shaft 240 , and the fastener 260 also abuts against another front shock-absorbing soft cover assembly 230 . In this embodiment, the front-mounted center column shaft 240 is sequentially passed through the front support base 210, the rolling friction pressure-dividing intervention component 250, one of the front shock absorber soft cover components 230, the front bracket bridge rod 220 and the other front shock absorber soft cover component 230, and the first end of the front-mounted center column shaft 240 abuts against the front support base 210, the fastener 260 is sleeved on the second end of the front-mounted center column shaft 240, and the fastener 260 also abuts against the other front shock absorber soft cover component 230, so that the front support base 210, the rolling friction pressure-dividing intervention component 250, one of the front shock absorber soft cover components 230, the front bracket bridge rod 220 and the other front shock absorber soft cover component 230 abut in sequence, thereby making the front support base 210, the rolling friction pressure-dividing intervention component 250, the front bracket bridge rod 220 and the two front shock absorber soft cover components 230 installed on the front-mounted center column shaft 240.

[0056] like Figure 4 As shown, in one embodiment, the fastener 260 is threadedly connected to the front mounting center column shaft 240, so that the fastener 260 is detachably connected to the front mounting center column shaft 240, improving the convenience of disassembly and assembly. In this embodiment, the tightness of the fastener 260 can be adjusted by twisting the fastener 260, thereby adjusting the downward force required to rotate the front support bridge rod 220.

[0057] In one embodiment, there are multiple planar rolling elements (not shown) to better reduce the rotational resistance of the front bracket bridge rod 220.

[0058] In one embodiment, the restraining member 251 is formed with at least one rolling groove, and each planar rolling member (not shown) rolls in the corresponding rolling groove to avoid the problem of each planar rolling member (not shown) deviating from the restraining member 251, thereby ensuring that each planar rolling member (not shown) can perform its function.

[0059] like Figure 4As shown, in one embodiment, the rolling friction pressure-dividing intervention component 250 further includes a first rotation limiting plate 252, which is rotationally connected to one side of the restraining member 251. The first rotation limiting plate 252 is also rollingly connected to each planar rolling member (not shown). The first rotation limiting plate 252 is also connected to the force-bearing end of the front shock-absorbing soft cover component 230, so that the force-bearing end of the front shock-absorbing soft cover component 230 is connected to the planar rolling member (not shown) through the first rotation limiting plate 252. In this embodiment, when the front support bridge rod 220 rotates, that is, when the plate body 100 and the front support base 210 swing, the first rotation limiting plate 252 rotates, and each planar rolling member (not shown) is rollingly connected to the first rotation limiting plate 252, so that the rolling friction pressure-dividing intervention component 250 plays the effect of reducing the rotational resistance of the front support bridge rod 220. Since the first rotation limit plate 252 is rotationally connected to one side of the restraining member 251, the first rotation limit plate 252 restrains the rolling position of each planar rolling member (not shown in the figure), inhibits each planar rolling member (not shown in the figure) from escaping from the corresponding rolling groove, improves the position stability of each planar rolling member (not shown in the figure), and further ensures that each planar rolling member (not shown in the figure) has the effect of reducing the rotation resistance of the front bracket bridge rod 220.

[0060] like Figure 4 As shown, in one embodiment, the rolling friction pressure-dividing intervention component 250 further includes a second rotation limiting piece 253, which is rotationally connected to one side of the restraining member 251. The second rotation limiting piece 253 is also connected to the front support base 210, so that the flat rolling element (not shown) is connected to the front support base 210 through the second rotation limiting piece 253. In this embodiment, when the front support bridge rod 220 rotates, that is, when the plate body 100 and the front support base 210 swing, the second rotation limiting piece 253 rotates, and each flat rolling element (not shown) is rollingly connected to the second rotation limiting piece 253, so that the rolling friction pressure-dividing intervention component 250 plays the effect of reducing the rotational resistance of the front support bridge rod 220. Since the second rotation limit plate 253 is rotationally connected to one side of the restraining member 251, the second rotation limit plate 253 restrains the rolling position of each planar rolling member (not shown in the figure), inhibits each planar rolling member (not shown in the figure) from escaping from the corresponding rolling groove, improves the position stability of each planar rolling member (not shown in the figure), and further ensures that each planar rolling member (not shown in the figure) has the effect of reducing the rotation resistance of the front bracket bridge rod 220.

[0061] like Figure 4 As shown, in one embodiment, front wheel axles 222 are symmetrically protruded on opposite sides of the front support bridge rod 220 , and each front wheel axle 222 is located on one side of the front mounting center column axis 240 adjacent to the middle of the plate body 100 .

[0062] like Figure 5 and Figure 6As shown, in one embodiment, the rear bracket 300 of the skateboard includes a rear support base 310, a rear bracket bridge rod 320, a rear shock absorber soft cover assembly 330 and a rear mounting center column shaft 340. The rear mounting center column shaft 340 is sequentially passed through the rear support base 310, the rear shock absorber soft cover assembly 330 and the rear bracket bridge rod 320. The rear bracket bridge rod 320 is also provided with a rear center column support shaft 311 rotatably connected to the rear support base 310. The rear shock absorber soft cover assembly 330 is respectively abutted against the rear support base 310 and the rear bracket bridge rod 320.

[0063] like Figure 6 As shown, in one embodiment, rear wheel axles 321 are symmetrically protruded on opposite sides of the rear support bridge rod 320, and each rear wheel axle 321 is located on one side of the rear mounting center column axis 340 adjacent to the center of the board body 100. In this embodiment, when the user swings the board, the synchronous rotation of the rear support bridge rod 320 and the front support bridge rod 220 makes the land surfing board 10 more effortless, smoother and more stable.

[0064] like Figures 7 to 9 As shown, in one embodiment, a first annular guide groove 2521 is formed on one side of the first rotation-limiting piece 252 adjacent to the restraining member 251. A first annular guide bar 2511 is protrudingly provided on one side of the restraining member 251 adjacent to the first rotation-limiting piece 252. The first annular guide bar 2511 is rotatably disposed in the first annular guide groove 2521. Furthermore, a first engaging portion 2512 is protrudingly provided on the first annular guide bar 2511 for guiding. A first engaging groove 2522 is formed on the first rotation-limiting piece 252 within the first annular guide groove 2521. The first engaging portion 2512 is engaged with the first engaging groove 2522, so that the first rotation-limiting piece 252 is rotatably connected to one side of the restraining member 251.

[0065] In order to improve the smoothness of the first rotation limiting piece 252 rotating on the restraining member 251, as shown in FIG. Figure 9 As shown, in one embodiment, the rolling friction pressure-dividing intervention component 250 also includes a plurality of first rolling balls 254, and the plurality of first rolling balls 254 are arranged in the first annular guide groove 2521, and each first rolling ball 254 is respectively rollingly connected to the first rotation limit plate 252 and the restraining member 251, so that the first rotation limit plate 252 is rollingly connected to the restraining member 251 through the plurality of first rolling balls 254, thereby reducing the friction between the first rotation limit plate 252 and the restraining member 251, improving the smoothness of the rotation of the first rotation limit plate 252, reducing the rotation resistance of the front bracket bridge rod 220, improving the steering flexibility of the front bracket bridge rod 220, and making the sliding smoother.

[0066] like Figure 8 and Figure 9As shown, in one embodiment, a second annular guide bar 2531 is protruding from a side of the second rotation-limiting piece 253 adjacent to the restraining member 251. A second annular guide groove 2513 is formed on a side of the restraining member 251 adjacent to the second rotation-limiting piece 253. The second annular guide bar 2531 is rotatably disposed in the second annular guide groove 2513. Furthermore, a second engaging portion 2532 is protruding from the second annular guide bar 2531. A second engaging groove 2514 is formed in the second annular guide groove 2513 of the restraining member 251. The second engaging portion 2532 engages with the second engaging groove 2514, thereby rotatably connecting the second rotation-limiting piece 253 to a side of the restraining member 251.

[0067] In order to improve the smoothness of the second rotation limiting piece 253 rotating on the restraining member 251, as shown in FIG. Figure 8 As shown, in one embodiment, the rolling friction pressure-dividing intervention component 250 also includes a plurality of second rolling balls 255, and the plurality of second rolling balls 255 are arranged in the second annular guide groove 2513, and each second rolling ball 255 is respectively rollingly connected to the second rotation limit plate 253 and the restraining member 251, so that the second rotation limit plate 253 is rollingly connected to the restraining member 251 through the plurality of second rolling balls 255, thereby reducing the friction between the second rotation limit plate 253 and the restraining member 251, improving the smoothness of the rotation of the second rotation limit plate 253, reducing the rotation resistance of the front bracket bridge rod 220, improving the steering flexibility of the front bracket bridge rod 220, and making the sliding smoother.

[0068] like Figure 8 As shown, in one embodiment, a first annular rolling groove 2523 is formed on one side of the first rotation limit plate 252 adjacent to the front shock absorber soft cover assembly 230, and a second annular rolling groove 2301 is formed on the corresponding front shock absorber soft cover assembly 230. The first rotation limit plate 252 abuts against the corresponding front shock absorber soft cover assembly 230 and closes the first annular rolling groove 2523 and the second annular rolling groove 2301 to form an annular rolling cavity. The rolling friction pressure-dividing intervention assembly 250 also includes a plurality of third rolling balls 256. The plurality of third rolling balls 256 are arranged in the annular rolling cavity, and each third rolling ball 256 is respectively connected to the first rotation limit plate 252 and the corresponding front shock absorber soft cover assembly 240 in a rolling manner, thereby reducing the friction between the first rotation limit plate 252 and the corresponding front shock absorber soft cover assembly 240, thereby reducing the rotation resistance of the front bracket bridge rod 220, improving the steering flexibility of the front bracket bridge rod 220, and making the sliding smoother.

[0069] In one embodiment, the front shock-absorbing cover 231 is a PU structure, that is, the front shock-absorbing cover 231 is made of PU material, so that the front shock-absorbing cover 231 has sufficient hardness and supporting force.

[0070] It can be understood that when the front bracket bridge rod 220 rotates, the front shock absorber sleeve 231 is compressed and twisted. Since the front shock absorber sleeve 231 is a PU structure, the strength of the front shock absorber sleeve 231 is relatively high, which makes the front shock absorber sleeve 231 resist the torsion force relatively large. This torsional resistance will hinder the rotation of the front bracket bridge rod 220 and become resistance.

[0071] In order to reduce the torsional resistance of the front shock-absorbing sleeve 231, as shown in FIG. Figure 10 and Figure 11 As shown, in one embodiment, a hollow groove 2311 is formed inside each front shock-absorbing sleeve 231 along the extension direction of the front mounting center column shaft 240, that is, a hollow groove 2311 is formed inside each front shock-absorbing sleeve 231 along the extension direction. In this embodiment, when each front shock-absorbing sleeve 231 is subjected to torsion, each front shock-absorbing sleeve 231 will deform into the hollow groove 2311, reducing the force of each front shock-absorbing sleeve 231 to resist torsion, thereby reducing the resistance to rotation of the front support bridge rod 220, improving the flexibility of rotation of the front support bridge rod 220, and making sliding more stable and smooth. Furthermore, each hollow groove 2311 runs through the corresponding front shock-absorbing sleeve 231, making the force of each front shock-absorbing sleeve 231 to resist torsion smaller.

[0072] It can be understood that since each front shock absorber sleeve 231 is sleeved on the front mounting center column shaft 240, there is friction between each front shock absorber sleeve 231 and the front mounting center column shaft 240. When each front shock absorber sleeve 231 twists, the corresponding friction force will generate resistance to the twisting of the corresponding front shock absorber sleeve 231, and then generate resistance to the rotation of the front bracket bridge rod 220.

[0073] In order to reduce the friction between each front shock-absorbing sleeve 231 and the front mounting center column shaft 240, as shown in FIG. Figure 11 As shown, in one embodiment, a drag reducing groove 2312 is formed on the inner wall of each front shock absorber sleeve 231 to reduce the contact area between each front shock absorber sleeve 231 and the front mounting center column shaft 240, thereby reducing the friction between each front shock absorber sleeve 231 and the front mounting center column shaft 240, thereby reducing the torsional resistance of each front shock absorber sleeve 231, reducing the rotational resistance of the front bracket bridge rod 220, and improving the rotational flexibility of the front bracket bridge rod 220.

[0074] like Figure 11 As shown, further, the drag reduction groove 2312 of each front shock absorber sleeve 231 is an annular groove, and the drag reduction groove 2312 of each front shock absorber sleeve 231 is arranged around the extension direction of the corresponding front shock absorber sleeve 231, so that the contact area between each front shock absorber sleeve 231 and the front mounting center column shaft 240 is smaller, thereby making the rotation flexibility of the front bracket bridge rod 220 higher.

[0075] like Figure 11As shown, in one embodiment, the drag reduction groove 2312 is used to accommodate lubricating liquid so that the lubricating liquid contacts the outer wall of the front mounting center column shaft 240, thereby allowing the lubricating liquid to flow to the entire outer wall of the front mounting center column shaft 240, thereby reducing the friction between each front shock absorber sleeve 231 and the front mounting center column shaft 240, thereby reducing the torsional resistance of each front shock absorber sleeve 231, and thereby reducing the rotational resistance of the front bracket bridge rod 220, thereby improving the rotational flexibility of the front bracket bridge rod 220.

[0076] like Figure 11 As shown, in one embodiment, the drag reducing groove 2312 is an arc-shaped groove, so as to improve the adsorption effect of the drag reducing groove 2312 on the lubricating fluid, reduce the leakage of the lubricating fluid, and improve the lubricating effect of the lubricating fluid.

[0077] Compared with the prior art, the present invention has at least the following advantages:

[0078] 1. When the plate body 100 swings, the front support base 210 swings and squeezes the front shock-absorbing soft cover assembly 230. When the front shock-absorbing soft cover assembly 230 is compressed to a certain extent, the front shock-absorbing soft cover assembly 230 will push the flat rolling element (not shown) to roll relative to the force-bearing end of the front shock-absorbing soft cover assembly 230 and at least one of the front support base 210, thereby causing the front shock-absorbing soft cover assembly 230 to rotate with the front bracket bridge rod 220 while being compressed, thereby reducing the resistance to the rotation of the front bracket bridge rod 220, improving the steering flexibility of the front bracket bridge rod 220, and making sliding smoother.

[0079] 2. Since the front shock absorber soft cover assembly 230 rotates with the front bracket bridge rod 220 while being compressed, the friction on the front shock absorber soft cover assembly 230 is reduced, thereby increasing the service life of the front shock absorber soft cover assembly 230.

[0080] 3. Since the resistance to the rotation of the front support bridge rod 220 is small, the maximum static friction force is small, which allows the user to drive the support bridge rod to rotate at a larger angle, that is, increases the rotation angle of the support bridge rod and makes sliding easier.

[0081] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
