[0002] As the number of battery life increases, the mileage of the prior art electric scooters also increases. However, because the design requirements are light or extremely light, the structure to protect the battery is also very important. For example, the patent number CN2023102180794 discloses a scooter body, including: a frame body, the upper end of which is concave downward to form a receiving cavity; a cover plate, the front end of which is connected to the front side of the receiving cavity through a hinge assembly, and the rear end of the cover plate is movably connected to the rear end of the receiving cavity to seal the receiving cavity; wherein the hinge assembly has at least: a rotating seat 1, which is installed on the upper inner wall of the receiving cavity, and a sliding space is provided on the rotating seat 1; a rotating seat 2, which is installed on the front inner wall of the cover plate; the rotating seat 2 is connected to the sliding space of the rotating seat 1 through an anti-slip rotating structure. The present invention utilizes the cooperation between the rotating seat 1 and the rotating seat and the anti-slip rotating structure to reduce the amplitude of shaking, ensure stability during use, and can achieve built-in installation, so that the hinge assembly cannot be seen on the outside of the vehicle body, and the aesthetics are guaranteed. Although this structure greatly improves the protection of the battery, this battery protection structure is very bulky. It is purely a matter of piling up thickness and replacing stronger materials on the main metal frame of the scooter frame. This increased thickness increases the overall weight of the scooter, which reduces the scooter's operational flexibility and reduces the cruising range. Replacing stronger metal materials will increase production costs, reduce market application and promotion capabilities, and reduce competitiveness. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides an electric scooter with a side protection structure, which is provided with an installable and replaceable side protection bar structure, which can improve the protection of the scooter frame body and its internal battery without increasing the thickness of the scooter frame body metal frame and the overall weight of the scooter.

[0004] The utility model is realized through the following contents: an electric scooter with a side protection structure comprises a front wheel frame, a vehicle main frame and a rear wheel frame, wherein the front wheel frame is longitudinally arranged at the head end of the vehicle main frame, and the rear wheel frame is connected and arranged at the tail end of the vehicle main frame, wherein: the vehicle main frame comprises a box frame, a box cover and a box protection shell, the box frame is arranged inside the box protection shell, and the box cover is arranged on the box frame; the box protection shell is connected to an outer lining protection plate, and the outer lining protection plate is provided with a protection bar.

[0005] By adopting the above technology, the pure iron box structure of the owner's frame in the prior art is improved, and a three-layer structure of a split anti-collision box frame, a box protective shell, and an outer lining protection plate with excellent functions is added. The buffering capacity is strong, and the electronic structure and battery arranged inside the box frame are well protected, so that the electric scooter can use lithium-ion batteries, polymer lithium batteries, etc. more safely. Compared with increasing the thickness and strength of the box structure related to the entire owner's frame, the cost does not increase in comparison, which improves the market application promotion and competitiveness. The protective bar has a better ability to resist impact, and it can be replaced and replaced very conveniently.

[0006] Preferably, the box protective shell includes a bottom plate and side panels bent upward on both sides to form a concave-shaped structure, and the top and bottom of the side panels are provided with fixed slide grooves, and the outer lining protective plate is inserted into the fixed slide grooves and fixedly connected to the outer wall of the side panels.

[0007] Preferably, the outer lining protection plate includes a hard outer plate and a buffer inner plate, the hard outer plate is square, trapezoidal, triangular or polygonal, and at least one connecting rod slot is arranged on the outer side, the protection rod is inserted into the connecting rod slot, and the buffer inner plate is arranged on the inner wall of the hard outer plate. The combination of hard and soft can resist collision and have very good buffering ability, and the internal buffer inner plate can prevent the battery from being broken and squeezed after being hit and squeezed.

[0008] Preferably, the protection bar is a solid or hollow square tube or round tube. When the protection bar is a hollow structure, the minimum tube diameter is 8 cm and the minimum tube thickness is 2 cm. The solid square tube or round tube can greatly increase the ability of the protection bar to resist impact, and because it is set at the outermost end of the outer lining protection plate, that is, the outermost position of the side of the entire main frame, it can resist impact in the first place. If the protection bar is a hollow structure, it can play a role in the side opening and ventilation to form a jet tube structure, which can reduce wind resistance.

[0009] Preferably, the head and tail ends of the outer lining protection plate are also provided with anti-collision air guide connectors, and the anti-collision air guide connectors are provided with ventilation holes. The head and tail ends of the protection bar are inserted into the ventilation holes of the anti-collision air guide connectors for fixing and being protected by the anti-collision air guide connectors. The anti-collision air guide connectors are mainly used to protect the front of the main frame of the vehicle.

[0010] Preferably, the anti-collision air guide connector is made of plastic or rubber, which has low cost, excellent anti-collision performance, and can well protect the side of the head and tail sections.

[0011] Preferably, the thickness of the anti-collision air guide connector is greater than the thickness of the outer lining protection plate. This structure can make the anti-collision air guide connector protrude outward as reasonably as possible, resist oblique impact, prevent the protection bar from being directly impacted, and avoid large displacement when impacted.

[0012] Preferably, the protection bar is L-shaped. The L-shaped protection bar can prevent stabbing if it protrudes backwards in the case of a direct impact from the front side.

[0013] Preferably, a wind shield is inserted into the ventilation hole, and the wind shield is connected to the protection bar. The main function of the wind shield is to fix the solid protection bar, and when the protection bar is a hollow structure, it directly prevents it from having a wind guiding effect.

[0014] Preferably, the surface of the protection bar is also affixed with a reflective rubber strip, which can protect against some minor scratches and can also serve as a warning and decoration during use.

[0015] Preferably, a bar slot is provided on the hard outer plate of the outer lining protection plate, which is used to fix and position the protection bar, as close to the protection bar as possible, so that the soft and hard parts and the protection bar work together.

[0016] Compared with the prior art, the utility model has the following beneficial effects: 1. It improves the pure iron box structure of the vehicle owner frame of the prior art, adds a three-layer structure of a split anti-collision box frame, a box protection shell, and an outer lining protection plate, which has excellent functions, has strong buffering capacity, and well protects the electronic structure and battery set inside the box frame, so that the electric scooter can use lithium-ion batteries, polymer lithium batteries, etc. more safely. Compared with increasing the thickness and strength of the box structure related to the entire vehicle owner frame, the cost does not increase, which improves the market application promotion and competitiveness;

[0017] 2. The outer lining protection plate is a double-layer structure, combining soft and hard, which can resist collision and have very good buffering ability. The internal buffer inner pad can prevent the battery from being broken and squeezed after being hit;

[0018] 3. The protection bar has a relatively good ability to resist impact, and it can be replaced and is very convenient to replace. Because it is set at the outermost end of the outer lining protection plate, which is the outermost position on the side of the entire vehicle main frame, it can resist impact in the first time. If the protection bar is a hollow structure, it can play a role in side ventilation to form a jet pipe structure, which can reduce wind resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The main embodiment of an electric scooter with a side protection structure is realized by the following contents: An electric scooter with a side protection structure, as in the prior art, is mainly as follows Figure 1-2 As shown, it includes a front wheel frame 1, a main frame 2, and a rear wheel frame 3. The front wheel frame 1 is longitudinally arranged at the head end of the transversely arranged main frame 2, and is respectively provided with a direction rod 19 for controlling the direction, and a front wheel 20 arranged at the bottom of the direction rod 19. The rear wheel frame 3 is provided with a rear wheel 22 and is connected to the tail end of the main frame 2. The main frame 2 is mainly provided with a core circuit control structure and a power supply structure, mainly a battery 21, wherein: Figure 3-5 As shown, the vehicle main frame 2 includes a box frame 4, a box cover 5, and a box protection shell 6. The box frame 4 is arranged inside the box protection shell 6, and the box cover 5 is arranged on the box frame 4;

[0028] like Figure 5As shown, the box protective shell 6 includes a bottom plate 9 and side panels 10 bent upward on both sides to form a concave shape structure, and the top and bottom of the side panels 10 are provided with fixed slide grooves 11, and the outer lining protection plate 7 is inserted into the fixed slide grooves 11 and fixedly connected to the outer wall of the side panels 10.

[0029] like Figure 5 As shown, the outer lining protection plate 7 includes a hard outer plate 12 and a buffer inner pad 13. The hard outer plate 12 is square, trapezoidal, triangular or polygonal, and at least one connecting rod slot 13 is provided on the outer side. The connecting rod slot 13 is inserted into the protection bar 8, and the buffer inner pad 13 is provided on the inner wall of the hard outer plate 12. The combination of soft and hard can not only resist collision, but also have very good buffering ability. The internal buffer inner pad can also prevent the battery from being crushed and squeezed after being hit. The box protective shell 6 is connected to the outer lining protection plate 7, and the outer lining protection plate 7 is provided with a protection bar 8.

[0030] Continue watching Figure 5 The protection bar 8 is a solid or hollow square tube or round tube. Two types are shown in the figure. The square tube is mainly to fit the shape of the bar slot, while the round tube has low procurement cost and is easy to make. When the protection bar 8 is a hollow structure, the diameter of the tube body is 8cm and the thickness of the tube body is 2cm. The anti-collision degree can reach the same level as the 5~3cm thick side panel 10. If it is a solid tube body, it can play the same anti-collision ability. The solid square tube or round tube can greatly increase the ability of the protection bar to resist impact, and because it is set at the outermost end of the outer lining protection plate, that is, the outermost position on the side of the entire vehicle main frame, it can resist impact in the first time.

[0031] By adopting the above technology, the pure iron box structure of the owner's frame in the prior art is improved, and a three-layer structure of a split anti-collision box frame, a box protective shell 6, and an outer lining protection plate with excellent functions is added. The buffering capacity is strong, and the electronic structure and battery arranged inside the box frame are well protected, so that the electric scooter can use lithium-ion batteries, polymer lithium batteries, etc. more safely. If the thickness and strength of the box body structure related to the entire owner's frame are increased, the cost does not increase by comparison, which improves the market application promotion and competitiveness. The protective bumper has a better ability to resist impact. Once the bumper is damaged, we can replace it like a car, and the replacement is very convenient and the cost is low.

The anti-collision air guide connectors are mainly used to protect the front of the main frame of the vehicle, and the protection bar is a hollow structure. After the electric vehicle starts running, the side air will be concentrated by the anti-collision air guide connectors into the hollow bumper, and the air is ventilated to form a jet tube structure, which can reduce wind resistance.

[0033] Preferably, the anti-collision air guide connector 14 is made of plastic or rubber, which has low cost, excellent anti-collision performance, and can well protect the side of the head and tail sections.

[0034] Preferably, the thickness of the anti-collision air guide connector 14 is greater than the thickness of the outer lining protection plate 7. This structure can protrude the anti-collision air guide connector as far as possible to resist oblique impact, prevent the protection bar from being directly impacted, and avoid large displacement when impacted.

[0035] Preferably, the protection bar 8 is L-shaped. The L-shaped protection bar 8 can not cause stabbing if it is directly hit by the front side, even if it protrudes backward.

[0036] Preferably, a wind shield 16 is inserted into the ventilation jack 15, and the wind shield 16 is connected to the protection bar 8. The main function of the wind shield is to fix the solid protection bar, and when the protection bar is a hollow structure, it directly prevents it from having a wind guiding effect.

[0037] As a preferred embodiment, the surface of the protection bar 8 is also affixed with a reflective rubber strip 17. The reflective rubber strip can protect some small scratches and can also play a warning and decorative role in use.

[0038] Preferably, the hard outer plate 12 of the outer lining protection plate 7 is provided with a bar slot 18. It is used to fix and position the protection bar, as close to the protection bar as possible, so that the soft and hard parts and the protection bar work together.
