Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame technology, specifically to a straddle-type electric vehicle frame. Background Technology

[0002] The electric vehicle frame is the core load-bearing structure of the entire vehicle, and its design directly affects the vehicle's safety, handling, and range.

[0003] For example, the Chinese authorized patent CN208882007U (A Frame for Easy Battery Storage and Retrieval in a Straddle-Type Electric Vehicle) includes a frame body and a seat frame and locking mechanism located above the frame body. A space for accommodating the battery is provided between the frame body and the seat frame. One end of the seat frame is detachably connected to the frame body via the locking mechanism, and the other end is rotatably connected to the frame body. The straddle-type electric vehicle frame provided by this utility model allows for quick battery storage and retrieval without removing the seat frame. The seat frame can be locked in place via the locking mechanism, ensuring driving safety. It features a simple structure, easy assembly and disassembly, and is suitable for industrial production.

[0004] However, most existing electric vehicle frames have side guards that are welded and fixed. When inspecting items installed inside the enclosure, the welded side guards can obstruct the inspection, making it inconvenient and difficult to remove. Furthermore, the welded fixing method makes it difficult to effectively protect different locations and is not suitable for installations of different sizes and structures. Therefore, it does not meet the current needs. To address this, we have proposed a straddle-type electric vehicle frame. Utility Model Content

[0005] The purpose of this utility model is to provide a straddle-type electric vehicle frame to solve the problems mentioned in the background art, where the side guards of most existing electric vehicle frames are welded and fixed. When inspecting objects installed in the enclosed interior space, the welded side guards can easily obstruct the inspection, making it inconvenient to inspect and remove them. Furthermore, the welded fixing method is not suitable for effectively protecting different positions and is not applicable to objects of different sizes and structures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straddle-type electric vehicle frame, comprising: a head seat, side connecting plates welded to both sides of the head seat, a support frame disposed between the two side connecting plates, and the support frame welded and fixed to the side connecting plates and the head seat, a vertical pole welded to the lower end of the side connecting plates, a base disposed at the lower end of the support frame, extension frames welded to both sides of the bend of the support frame, a reinforcing frame welded between the extension frames and the base, and a protective component disposed between one side of the vertical pole and the support frame.

[0007] Preferably, the protective component includes a protective plate, one end of the front surface of the protective plate is provided with a knob hole, and the knob hole penetrates the protective plate. Both sides of the support frame are provided with threaded holes corresponding to the knob hole. A fixing knob is inserted into one end of the knob hole, and one end of the fixing knob passes through the knob hole and is threadedly connected to the threaded hole. The protective plate rotates along the fixing knob through the knob hole.

[0008] Preferably, an adjustment plate is provided at the other end of the protective plate, and a groove is provided on the front surface of the adjustment plate, and the groove extends through the adjustment plate.

[0009] Preferably, a positioning post is inserted inside the chute, and one end of the positioning post is welded and fixed to the upright, while the other end of the positioning post is provided with a limiting seat.

[0010] Preferably, the protective assembly further includes a reinforcing plate, the upper surface of which is provided with a connecting slot, the connecting slot penetrating the protective plate, and the reinforcing plate being inserted along the connecting slot.

[0011] Preferably, the inner walls on both sides of the connecting slot are provided with bolt through grooves, and the bolt through grooves penetrate the protective plate. The front surface of the reinforcing plate is provided with an adjustment groove, and the adjustment groove penetrates the reinforcing plate. A fixing bolt is inserted into one end of the bolt through groove, and the other end of the fixing bolt passes through the bolt through groove and the adjustment groove and is then threaded and fixed with a nut.

[0012] Preferably, a stabilizing frame is welded between the bottom two sides of the upright and the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides a protective component between one side of the upright and the support frame. When installing the protective component, the protective plate is connected to the support frame through a fixing knob. Without tightening the fixing knob, the protective plate rotates along the fixing knob through the knob hole to protect different positions, rather than protecting only one position. This improves the range of protection adjustment and flexibility, and is suitable for electric vehicle objects of different sizes and structures. When rotating the protective plate, it slides along the outside of the positioning post through the sliding groove, and the limiting seat prevents one end of the protective plate from slipping off the positioning post, improving the stability of the protective plate installation. Even if the fixing knob falls off, the protective plate will not fall off, improving stability and safety. This solves the problem that most of the side protective frames of existing electric vehicle frames are welded and fixed. When inspecting objects installed in the inner space of the enclosure, the welded side protective frame is easy to block the inspection, making it inconvenient to remove. Furthermore, the welded fixing makes it inconvenient to effectively protect different positions and is not suitable for installation objects of different sizes and structures.

[0015] (2) By setting a vertically penetrating connecting slot on the upper surface of the protective plate, the reinforcing plate is inserted into the connecting slot, and the adjusting slot and the bolt penetrating slot are aligned. The plate is then fixed by fixing the bolt with an external nut. Multiple reinforcing plates can be installed, thereby increasing the protective range of the protective plate and improving safety.

A fixed knob 20 is inserted into one end of the threaded hole 22 and the knob hole 21. One end of the fixed knob 20 passes through the knob hole 21 and is threadedly connected to the threaded hole 22. The protective plate 10 rotates along the fixed knob 20 through the knob hole 21. One end of the fixed knob 20 passes through the knob hole 21 and is threadedly connected to the threaded hole 22, thus connecting the protective plate 10 to the support frame 2. Without tightening the fixed knob 20, the protective plate 10 can rotate along the fixed knob 20 through the knob hole 21 to adjust the angle of the protective plate 10, providing protection for different positions instead of just one position. This improves the range of protection adjustment and flexibility, making it suitable for electric vehicle parts of different sizes and structures. When the fixed knob 20 is tightened, a shock-absorbing pad is provided to reduce the possibility of loosening due to high-frequency vibration.

[0023] An adjustment plate 13 is provided at the other end of the protective plate 10. A sliding groove 14 is provided on the front surface of the adjustment plate 13, and the sliding groove 14 passes through the adjustment plate 13. A positioning post 16 is inserted inside the sliding groove 14, and one end of the positioning post 16 is welded and fixed to the upright 3. A limit seat 15 is provided at the other end of the positioning post 16. When the protective plate 10 is rotated, it slides along the outside of the positioning post 16 through the sliding groove 14, and the limit seat 15 prevents one end of the protective plate 10 from sliding off the positioning post 16, thereby improving the stability of the installation of the protective plate 10. Even if the fixing knob 20 is not installed, the protective plate 10 will not fall off, thus improving stability and safety.

[0024] The protective assembly 9 also includes a reinforcing plate 12. A connecting slot 11 is provided on the upper surface of the protective plate 10, penetrating the protective plate 10. The reinforcing plate 12 is inserted along the connecting slot 11. Bolt through grooves 19 are provided on both inner walls of the connecting slot 11, penetrating the protective plate 10. An adjustment groove 17 is provided on the front surface of the reinforcing plate 12, penetrating the reinforcing plate 12. A fixing bolt 18 is inserted into one end of the bolt through groove 19, and one end of the fixing bolt 18 passes through the bolt through groove 19 and the adjustment groove 17 before being fixed with a connecting nut and a shock-absorbing washer. The shock-absorbing washer improves the shock resistance of the fixing bolt 18, preventing loosening due to high-frequency vibration and improving connection stability. The reinforcing plate 12 is inserted into the connecting slot 11, with the adjustment groove 17 and bolt through groove 19 aligned, and fixed with an external nut attached to the fixing bolt 18. Figure 2 As shown, multiple reinforcing plates 12 can be installed to increase the protection range of the protective plate 10 and improve safety.
