Description

Technical Field

[0001] The utility model relates to the technical field of go-kart accessories, in particular to a high-strength anti-collision frame for go-karts. Background Art

[0002] A go-kart is a miniature sports car. Because its chassis is extremely low (only 4 centimeters off the ground), the driver's perceived speed is 2-3 times higher than the actual speed, meaning it feels like 300 kilometers per hour. Especially on curves, the lateral acceleration is 3-4 times that of gravity, giving the driver a thrill not possible in a typical race car. Go-karts are extremely popular in Europe, Japan, and other countries due to their simple structure, high safety, and exceptional racing characteristics.

[0003] Existing devices primarily enhance vehicle safety by adding an external anti-collision frame to the outer ring of the frame. Much of the existing technology resembles a new type of kart anti-collision beam. Patent number CN217705720U includes an anti-collision rubber ring wrapped around the periphery of the kart body, and a front anti-collision beam and an arc-shaped electromagnet mounted on the front and rear ends of the kart, respectively. The front anti-collision beam is arc-shaped and has a buffer assembly between it and the front end of the kart. The anti-collision rubber ring and the ends of the front anti-collision beam also have a common extrusion assembly, which is used to buffer the impact force on both ends of the front anti-collision beam. Compared to existing technologies, this application improves the kart's collision buffering capacity and optimizes the kart's safety issues, but the device still has room for improvement.

[0004] The existing device mainly installs an integrated anti-collision outer package on the outside of the frame, which makes it difficult to separately assemble the anti-collision components of the frame side wings and rear of some devices, resulting in some devices needing to replace the entire set of anti-collision frames. At the same time, some devices mainly fix the curved bumper on the front side of the frame, making it difficult for some devices to effectively absorb the kinetic energy of the kart collision, resulting in greater harm from the collision accident and reducing the safety and practicality of the device. Therefore, in order to solve the above problems, a high-strength anti-collision frame for karts is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength anti-collision frame for karts, so as to solve the problem that the existing devices in the prior art mentioned in the above background technology are mainly to install an integrated anti-collision outer package on the outside of the frame, making it difficult for some devices to separately assemble the anti-collision components of the frame side wings and rear, thereby causing some devices to need to replace the entire set of anti-collision frames. At the same time, some devices mainly fix the front side of the frame with an arc-shaped bumper, making it difficult for some devices to effectively absorb the kinetic energy of the kart collision, thereby causing greater harm in collision accidents.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-strength crash cage for a go-kart, comprising a frame, crash frames provided on the side wings and rear of the frame, a rotating column movably connected to the inner wall of the crash frame, a damping telescopic rod fixedly connected to the right side of the top of the frame, and a right side of the damping telescopic rod fixedly connected to a bumper;

[0007] An assembly mechanism is provided at the side and rear of the frame, and the assembly mechanism includes a fixing seat, the bottom of the fixing seat is fixedly connected to the side and rear of the top of the frame, and an energy absorbing mechanism is provided at the front of the frame, and the energy absorbing mechanism includes a limiting rod, and the left side of the limiting rod is fixedly connected to the middle of the right side of the frame.

[0008] Preferably, a bolt is inserted into the inner wall of the fixing seat, and the end of the bolt passes through the fixing seat and is threadedly connected with a fixing nut.

[0009] Preferably, the outer wall of the bolt is located inside the fixing seat and is sleeved with a connecting tube, and the outer wall of the connecting tube is fixedly connected to the upper outer side of the anti-collision frame.

[0010] Preferably, a card slot is fixedly connected to the lower outer side of the anti-collision frame, and a limiting strip is provided on the inner wall of the card slot, and the top of the limiting strip is fixedly connected to the bottom of the vehicle frame.

[0011] Preferably, sliding sleeves are sleeved on both sides of the outer wall of the limiting rod, and a spring is fixedly connected to the outer ring of the limiting rod between the side walls of the sliding sleeves.

[0012] Preferably, a traction rod is movably connected to the right side of the outer wall of the sliding sleeve, and the right end of the traction rod is movably connected to the left side of the safety rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model realizes the assembly of the anti-collision frame through the structures of the fixing seat, bolts, connecting tube, fixing nut, card slot and limit strip in the assembly mechanism, and the card slot is sleeved on the outer wall of the limit strip by moving the anti-collision frame, and the connecting tube is placed inside the fixing seat, and then the bolt is passed through the fixing seat and the connecting tube, and the fixing nut is sleeved on the end of the outer wall of the bolt, so that some devices can be assembled with the anti-collision components of the frame side wings and the rear separately, effectively avoiding the need for a full set of anti-collision frames, and improving the convenience and practicality of the device.

[0015] 2. The utility model uses the limit rod, sliding sleeve, spring and traction rod in the energy absorption mechanism. The safety bar hits the compression damping telescopic rod and drives the right end of the traction rod to slide to the left. The left end of the traction rod drives the sliding sleeve to slide symmetrically. The sliding sleeve compresses the spring, and the spring cooperates with the damping telescopic rod to absorb and buffer the kinetic energy of the impact, thereby realizing the energy absorption of the safety bar. The partial device can effectively absorb the kinetic energy of the kart collision, effectively reducing the harm of the collision accident, and improving the protection and practicality of the device.

[0024] The side and rear of the frame 11 are provided with an assembly mechanism 2, which includes a fixing seat 21, the bottom of the fixing seat 21 is fixedly connected to the side and rear of the top of the frame 11, and a bolt 22 is inserted into the inner wall of the fixing seat 21. The end of the bolt 22 passes through the fixing seat 21 and is threadedly connected with a fixing nut 24. Through this design, the bolt 22 is fixedly inserted on the inner wall of the fixing seat 21, and the outer wall of the bolt 22 is located inside the fixing seat 21 and is sleeved with a connecting tube 23. The outer wall of the connecting tube 23 is fixedly connected to the upper outer side of the anti-collision frame 12. Through this design, the connection tube 23 and the upper part of the anti-collision frame 12 are limited. A card slot 25 is fixedly connected to the lower outer side of the anti-collision frame 12, and a limit strip 26 is provided on the inner wall of the card slot 25. The top of the limit strip 26 is fixedly connected to the bottom of the frame 11. Through this design, stable limitation of the lower part of the anti-collision frame 12 is achieved.

[0025] An energy absorbing mechanism 3 is provided in front of the frame 11, and the energy absorbing mechanism 3 includes a limit rod 31. The left side of the limit rod 31 is fixedly connected to the middle part of the right side of the frame 11, and sleeves 32 are provided on both sides of the outer wall of the limit rod 31. A spring 33 is fixedly connected to the outer ring of the limit rod 31 between the side walls of the sleeve 32. Through this design, the sleeve 32 can slide in a limited position on the outer wall of the limit rod 31 and stretch the spring 33.

[0027] When the safety bar 15 needs to absorb energy, the safety bar 15 first hits the compression damping telescopic rod 14 and drives the right end of the traction rod 34 to slide to the left. The left end of the traction rod 34 drives the sliding sleeve 32 to slide symmetrically. The sliding sleeve 32 compresses the spring 33. The spring 33 cooperates with the damping telescopic rod 14 to absorb the kinetic energy of the buffer impact, thereby realizing the energy absorption operation of the safety bar 15. The operation ends here.
