Technical Field
[0001] The utility model relates to the technical field of skateboard frames, in particular to a lightweight skateboard frame. Background Art
[0002] An electric skateboard is a vehicle based on a traditional human-powered skateboard with an electric power kit. Electric skateboards are generally divided into two-wheel drive or single-wheel drive, and the most common transmission methods are hub motors and belt drives respectively. Its main power source is a lithium battery pack.
[0003] The existing electric skateboards have complex structures and relatively large self-weights. When carrying and transporting them, it is quite laborious. Moreover, due to the low chassis, the shock absorption effect is poor when encountering bumps.
[0004] Therefore, we propose a lightweight skateboard frame to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problems in the prior art that the self-weight of an electric skateboard is relatively large, it is quite laborious to carry and transport, and the shock absorption effect is poor, and to propose a lightweight skateboard frame.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A lightweight skateboard frame includes a battery box. Support pipes are fixedly connected to both the front and rear sides of the battery box. An inclined pipe is arranged on the left side of the battery box. The upper end of the inclined pipe is fixedly connected to a head pipe. The left ends of the two support pipes are both fixedly connected to the inclined pipe. The right ends of the two support pipes are fixedly connected to the same U-shaped plate. A cover body is fixedly covered on the upper end of the U-shaped plate. A tail fork is rotatably connected inside the U-shaped plate. A buffer mechanism for buffering the tail fork is arranged inside the U-shaped plate.
[0008] Preferably, both ends of the support pipe are bent towards the same side.
[0009] Preferably, a step is arranged at the lower end of the tail fork.
[0010] Preferably, the buffer mechanism includes a rotating plate rotatably connected to the inner side wall of the U-shaped plate. Two buffer rods are slidably penetrated through the rotating plate. A resisting piece is fixedly connected to the left end of the buffer rod. A spring is sleeved outside the buffer rod. The two ends of the spring are respectively fixedly connected to the resisting piece and the rotating plate. A pulling plate is fixedly connected to the right end of the buffer rod. The same rotating rod is rotatably penetrated through the two pulling plates. Both ends of the rotating rod are rotatably connected to the inner side wall of the step.
[0011] Preferably, a rotating shaft is arranged above the rotating rod. Both ends of the rotating shaft are rotatably penetrated through the tail fork and rotatably connected to the inner side wall of the U-shaped plate.
[0012] Preferably, rear wheel mounting grooves are provided on both arms of the tail fork.
[0013] Preferably, the battery box includes two fixing rods, and a plurality of U-shaped rods are fixedly connected between the two fixing rods.
[0014] Preferably, the plurality of U-shaped rods are evenly distributed in an array, and a footrest mounting plate is fixedly connected to the side wall of one of the U-shaped rods.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. By providing the inclined tube and the battery box, the battery box is assembled with simple fixing rods and U-shaped rods, and the overall structure is simple. The inclined tube is a hollow tube with a small weight, which greatly reduces its own weight, making it more labor-saving when carrying and transporting the scooter.
[0017] 2. By providing the buffer mechanism, when the scooter bumps, the tail fork rotates around the rotating shaft relative to the U-shaped plate. During the rotation, the rotating rod generates a position offset, the rotating rod pulls the buffer rod, and the buffer rod compresses the spring, thereby achieving a shock-absorbing effect. When the vibration amplitude is large, the inner wall of the step of the tail fork will contact the two pull plates, preventing the vibration amplitude from further increasing and avoiding the battery box contacting the ground due to too large a vibration amplitude. On the one hand, the shock-absorbing effect on the scooter is better, and on the other hand, the battery box can be protected to avoid the battery box colliding with the ground due to vibration.
[0018] The present utility model has a light self-weight, is more labor-saving in carrying and transporting, and has a good shock-absorbing effect, and can protect the battery box. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0025] Refer to Figures 1-4 , a lightweight skateboard frame, including a battery box 1. It should be noted that the battery box 1 includes two fixing rods 18. A plurality of U-shaped rods 19 are fixedly connected between the two fixing rods 18. Support tubes 2 are fixedly connected to both the front and rear sides of the battery box 1. Specifically, both ends of the support tube 2 are bent towards the same side. An inclined tube 3 is provided on the left side of the battery box 1. The upper end of the inclined tube 3 is fixedly connected to a head tube 4. The left ends of the two support tubes 2 are both fixedly connected to the inclined tube 3. The right ends of the two support tubes 2 are fixedly connected to the same U-shaped plate 5.
[0026] In the present invention, a cover body 6 is fixedly covered on the upper end of the U-shaped plate 5. A tail fork 7 is rotatably connected inside the U-shaped plate 5. Further, rear wheel mounting grooves 17 are provided on both arms of the tail fork 7. It is worth mentioning that a step 9 is provided at the lower end of the tail fork 7. A buffer mechanism 8 for buffering the tail fork 7 is provided inside the U-shaped plate 5. It should be noted that the buffer mechanism 8 includes a rotating plate 10 rotatably connected to the inner side wall of the U-shaped plate 5. Two buffer rods 11 are slidably penetrated through the rotating plate 10. An abutting piece 12 is fixedly connected to the left end of the buffer rod 11.
[0027] In the present invention, a spring 13 is sleeved outside the buffer rod 11. The two ends of the spring 13 are respectively fixedly connected to the abutting piece 12 and the rotating plate 10. A pulling plate 14 is fixedly connected to the right end of the buffer rod 11. It should be noted that the left edge of the step 9 is located above the pulling plate 14. The same rotating rod 15 is rotatably penetrated through the two pulling plates 14. It should be noted that a rotating shaft 16 is provided above the rotating rod 15. Both ends of the rotating shaft 16 are rotatably penetrated through the tail fork 7 and rotatably connected to the inner side wall of the U-shaped plate 5. Both ends of the rotating rod 15 are rotatably connected to the inner side wall of the step 9. It is worth mentioning that the plurality of U-shaped rods 19 are evenly distributed in an array. A footrest mounting plate 20 is fixedly connected to the side wall of one of the U-shaped rods 19.
[0028] In the present utility model, when the scooter jolts, the rear fork 7 rotates relative to the U-shaped plate 5 with the rotating shaft 16 as the center. During the rotation, the position of the rotating rod 15 is offset. The rotating rod 15 pulls the buffer rod 11, and the buffer rod 11 compresses the spring 13, thereby achieving the effect of shock absorption. When the vibration amplitude is large, the inner wall of the step 9 of the rear fork 7 will come into contact with the two pull plates 14, preventing the vibration amplitude from further increasing and avoiding the battery box 1 contacting the ground due to too large a vibration amplitude.
[0029] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, should be covered within the protection scope of the present utility model.
