[0001] This utility model relates to the field of go-kart frame technology, specifically a modular go-kart frame with adjustable length. Background Technology
[0002] Go-karts are miniature sports cars with a simple structure, consisting of a frame, a small engine, and four independent wheels. They combine racing and entertainment and are known as the cradle of Formula 1 racing. The main component of a go-kart is the frame, which is a miniature racing car skeleton welded from lightweight steel pipes. It is mainly used to support the weight of the car and transmit power. The frame is made of high-strength steel pipes, making it lightweight and strong. Compared with other racing cars, it is simpler, retaining only the necessary support structure.
[0003] The production and installation process of go-kart frames only involves assembling, transporting, and storing the entire frame. The large size of the go-kart frame easily increases or decreases space requirements. It's impossible to disassemble the frame for smaller transport and storage, and workers cannot quickly adjust the frame length during installation to accommodate different sizes of go-karts. During use, excessive impact forces can easily injure personnel and increase the damage to the frame. The system cannot mitigate impact forces, and impacts can easily damage mounting points on the frame. Furthermore, damaged mounting points cannot be quickly replaced. Therefore, this utility model is proposed to solve these problems. Utility Model Content

[0018] Example: Reference Figures 1-8 The diagram shows a modular go-kart frame with an adjustable length, comprising:
[0019] As a preferred embodiment of this example, Figures 2 to 8As shown, a frame base plate 1 has a frame beam 2 inserted into its upper surface. An extension rod 3 is slidably connected to one end of the frame beam 2. An extension groove is formed at the end of the frame beam 2 near the extension rod 3, and the extension rod 3 is slidably connected inside the extension groove. An extension hole is formed on the inner side wall of the extension groove, and an extension threaded hole is formed on the surface of the extension rod 3. The extension rod 3 is installed inside the extension groove via an extension bolt. A backrest frame 4 is sleeved onto one end of the extension rod 3. An adjustment assembly 5 is inserted inside the backrest frame 4. The adjustment assembly 5 includes a fixed base 501, an adjustment rod 502, an adjustment seat 503, a push rod seat 504, and an adjustment push rod 505. An adjusting rod 502 is slidably connected inside the fixed seat 501. One end of the adjusting rod 502 is sleeved with an adjusting seat 503. A push rod seat 504 is inserted into one side of the adjusting seat 503. An adjusting push rod 505 is installed on one side of the push rod seat 504. A fixing groove is formed on the upper surface of the fixed seat 501. The adjusting rod 502 is slidably connected inside the fixing groove. A fixing hole is formed on the inner side of the fixing groove. An adjusting threaded hole is formed on one side of the adjusting rod 502. The adjusting rod 502 is installed inside the fixed seat 501 by fixing bolts. A push rod threaded groove is formed on the side of the push rod seat 504 near the adjusting push rod 505. One end of the adjusting push rod 505... A fixed thread is provided, and the internal thread of the push rod thread groove passes through the fixed thread. An operating lever 6 is installed on the surface of the frame beam 2. A steering component 7 is installed inside the frame base plate 1. A front bumper connector 8 is installed on the lower surface of the frame base plate 1. A frame front bumper 9 is inserted into the front bumper connector 8. A mating seat 10 is sleeved on the surface of the frame front bumper 9. A front bumper seat 11 is installed on one side of the mating seat 10 by a mating bolt. A crash protection component 12 is inserted into one side of the front bumper seat 11. The crash protection component 12 includes a crash protection bolt 121, a crash protection seat 122, a crash protection spring 123, a spring seat 124, and a damper 125. The crash protection bolt 121... One end of the anti-collision seat 122 is threaded through, and one end of the anti-collision seat 122 is inserted with an anti-collision spring 123. One end of the anti-collision spring 123 is sleeved with a spring seat 124. One end of the spring seat 124 is inserted with a damper 125. One end of the anti-collision assembly 12 is inserted with an anti-collision rubber plate 13. A support seat 14 is inserted into the surface of the frame beam 2. An installation plate 15 is installed inside the support seat 14. Support threaded holes are opened on the inner bottom and inner side wall of the support seat 14. The installation plate 15 is installed inside the support seat 14 by support bolts. A frame plate 101 is provided on the lower surface of the frame base plate 1. A support rod 16 is inserted into the inside of the support seat 14.During use, the extension bolt is removed by rotating it, thus releasing it from the fixation of the extension rod 3 and the frame beam 2. The extension rod 3 is then slid back and forth within the extension groove of the frame beam 2 by pulling the back frame 4 to adjust its length. After the frame beam 2 and back frame 4 are adjusted, the extension bolt is screwed into the corresponding extended threaded hole in the extension hole, fixing the extension rod 3 and frame beam 2 in place. Rotating the extension bolt allows for quick installation and removal of the back frame 4 from the extension rod 3. This facilitates transportation and storage after production, reducing the space occupied by the larger frame size during transportation and storage, and allowing workers to quickly install the frame. The system allows for easy adjustment of the frame length and quick replacement of the frame in case of collision damage, reducing the need for complete frame replacement and increasing costs. By rotating and removing the fixing bolts, the fixing bolts are released from their attachment to the adjusting rod 502 and the fixing seat 501. Pulling the adjusting seat 503 allows the adjusting rod 502 to slide within the fixing groove to adjust its length. After adjustment, the fixing bolts are screwed into the adjusting threaded holes to secure the adjusting rod 502 and the fixing seat 501. The adjusting push rod 505 moves the adjusting seat 503 back and forth for adjustment. This allows workers to quickly adjust the equipment according to the installation position during frame installation, enabling rapid and efficient operation. The adjustment facilitates installation by workers. By rotating the connecting bolts, the front bumper mount 11 can be quickly installed and removed from one side of the connecting seat 10. In the event of an impact, the anti-collision rubber plate 13 collides with the impacting object. The backward movement of the anti-collision rubber plate 13 causes the anti-collision spring 123 and damper 125 to compress, relatively weakening the impact force generated by the anti-collision rubber plate 13. This effectively reduces the impact force transmitted from the anti-collision rubber plate 13 to the chassis floor 1 and chassis beam 2, minimizing the impact force that could cause injury or damage to the chassis. When the anti-collision rubber plate 13 collides with the impacting object, it causes damage to the front bumper 9 and chassis plate 101. When replacing the front bumper 9 after damage, the damaged frame plate 101 is cut using a cutting device. The mounting plate 15 is rotated from horizontal to vertical and installed into the support seat 14 by rotating the support bolts. The support rod 16 is removed and installed into the support seat 14 for support. After the mounting plate 15 is installed from horizontal to vertical, the new front bumper 9 is installed under the frame base plate 1. This allows workers to quickly install the new front bumper 9 under the frame base plate 1, reducing the risk of not being able to replace the front bumper 9 after an impact that damages the frame plate 101, thus reducing the impact on normal use and the increased maintenance costs that would require replacing the entire frame plate 101 after damage.
[0020] The working principle of this practical application is as follows: During use, the worker rotates and removes the extension bolt, releasing it from the fixation of the extension rod 3 and the frame beam 2. Pulling the backrest frame 4 allows the extension rod 3 to slide back and forth within the extension groove of the frame beam 2 to adjust its length. After adjustment, the extension bolt is screwed into the corresponding extension threaded hole in the extension hole, fixing the extension rod 3 and frame beam 2. Rotating the extension bolt allows the backrest frame 4 to be quickly installed and removed from the extension rod 3, facilitating transportation and storage after production. The worker then rotates and removes the fixing bolt, releasing it from the fixation of the adjusting rod 502 and the fixing seat 501. Pulling the adjusting seat 503 allows the adjusting rod 502 to slide within the fixing groove to adjust its length. After adjustment, the fixing bolt is screwed into the adjusting threaded hole to fix the adjusting rod 502 and the fixing seat 501. The adjusting push rod 505 moves the adjusting seat 503 back and forth for adjustment. This allows workers to quickly adjust the frame according to the installation position during frame installation. In the event of an impact, the anti-collision rubber plate 13 collides with the impacting object. The backward movement of the anti-collision rubber plate 13 compresses the anti-collision spring 123 and damper 125, relatively weakening the impact force generated by the anti-collision rubber plate 13. This effectively reduces the impact force transmitted from the anti-collision rubber plate 13 to the chassis floor plate 1 and chassis beam 2. If the front bumper 9 and chassis plate 101 are damaged during the collision between the anti-collision rubber plate 13 and the impacting object, the worker can quickly rotate the connecting bolts to allow the front bumper mount 11 to be repositioned. The damaged frame plate 101 is cut by using a cutting device when replacing the front bumper 9 of the frame. The mounting plate 15 is changed from horizontal to vertical by rotating the support bolt and installed into the support seat 14. The support rod 16 is removed and installed into the support seat 14 for support. After the mounting plate 15 is changed from horizontal to vertical, the new front bumper 9 of the frame is installed under the frame base plate 1, which makes it convenient for workers to quickly install the new front bumper 9 of the frame under the frame base plate 1.
