Description

Technical Field

[0001] This invention relates to the field of scooter technology, and more specifically to an inflatable hydrogen fuel cell electric scooter. Background Technology

[0002] Compared to conventional batteries, hydrogen fuel cells replace the charging process with a gas filling process, allowing for faster energy replenishment. Compared to fuel-powered devices, they are quieter, less polluting, and produce no exhaust fumes. To a certain extent, they combine the advantages of fuel-powered devices and batteries. With the miniaturization of hydrogen fuel cells, they can also be applied to devices such as drones and scooters.

[0003] When folding, existing electric scooters typically bend the handlebar to a position close to the footboard, changing the entire device from an L-shape to a long, narrow shape. When carrying them, you need to hold the handlebar and lift the entire device. Although electric scooters are relatively lightweight, they still weigh over ten kilograms, making them quite strenuous to lift and carry. Furthermore, when lifted, the front and rear wheels are at thigh or knee height and protrude forward, making it easy to bump into other pedestrians when navigating through areas with heavy foot traffic, which is quite inconvenient. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide an inflatable hydrogen fuel cell electric skateboard. Through the arrangement of the support components, when folded for carrying, it comprises an M-shaped folding base plate 1, base plate 2, base plate 3, and base plate 4. The bottom surface of base plate 1 is attached to the bottom surface of base plate 2, the top surface of base plate 2 is attached to the top surface of base plate 3, and the bottom surface of base plate 3 is attached to the bottom surface of base plate 4. This allows the front and rear wheels to be staggered and coaxial. The handlebars are disengaged from the fork, the handlebars are deflected downwards, and the handlebars are limited, achieving overall folding. When folded, the skateboard resembles a rolling suitcase. During movement, the front and rear wheels are on the ground, and pulling the handlebars propels the skateboard forward, allowing it to be dragged along the ground for easy carrying and transport. Furthermore, with both wheels on the ground, compared to a lift-type skateboard where both wheels are suspended in the air, it is less likely to scratch other pedestrians, making it more convenient.

[0005] The objective of this invention can be achieved through the following technical solutions: An inflatable hydrogen fuel cell electric skateboard includes a support assembly. The support assembly includes a base plate one, a base plate two rotatably connected to one end of the base plate one, a base plate three rotatably connected to one end of the base plate two, and a base plate four rotatably connected to one end of the base plate three. A rear wheel is mounted on the other end of the base plate one. The rotation axis between the base plate one and the base plate two is located on the bottom side of the base plate one, the rotation axis between the base plate two and the base plate three is located on the top side of the other end of the base plate two, and the rotation axis between the base plate three and the base plate four is located on the bottom side of one end of the base plate three. A battery box is fixedly connected to the top surface of the base plate four. A control component is provided at one end of the base plate four. The control component includes a connecting plate. A sleeve is fixedly connected to one end of the connecting plate. A front fork is rotatably connected to the inner wall of the sleeve. A front wheel is installed at the bottom end of the front fork. The other end of the connecting plate is fixedly connected to one end of the base plate four. A handlebar is provided above the top of the front fork. An air tank cavity is opened at the bottom end of the handlebar. An air tank is fixedly connected to the inner wall of the air tank cavity. The air tank is provided with an inflation port and an output end. The output end of the air tank is connected to the battery box. A flexible hose connects the air intakes. A connecting module is connected between the bottom of the handlebar and the top of the fork. The battery box drives the front wheel, which houses a hub motor. Hydrogen is supplied to the battery box from a gas tank. The battery box consumes hydrogen to generate electricity, driving the front wheel to rotate and move forward. When folded for carrying purposes, it folds into an M-shape with base plates one, two, three, and four. The bottom surface of base plate one fits against the bottom surface of base plate two, the top surface of base plate two fits against the top surface of base plate three, and the bottom surface of base plate three fits against the bottom surface of base plate four, thus enabling… With the front and rear wheels offset from each other and coaxial, the handlebars are disengaged from the fork and tilted downwards. Through the connection module, the handlebars move laterally to one side while tilting downwards, thus moving the handlebars above the position between the front and rear wheels and limiting the position of the handlebars, achieving overall folding. When moving, the front and rear wheels are on the ground, and pulling the handlebars propels the whole thing forward, making it easy to carry and transport. When placed, the top of the fork is in contact with the ground, and together with the front and rear wheels, it can be placed upright, making it even more convenient to carry and use.

[0006] Furthermore, one end of the second base plate, both ends of the third base plate, and the other end of the fourth base plate are all inclined sides, and the inclination angles of each inclined side are the same, so that the second base plate, the third base plate, and the fourth base plate form an N-shape after folding, and the side of the second base plate is parallel to and misaligned with the side of the fourth base plate, thereby making the front wheel and the rear wheel pass through the shaft and are misaligned after folding.

[0007] Furthermore, the following features are provided: a cavity is formed on one side wall of the first base plate, and an insert plate is slidably connected to the inner wall of the first cavity; side grooves are slidably connected to the inner walls of both sides of the first cavity; a cavity is formed on one end of the second base plate, and an insert plate is slidably connected to the inner wall of the second cavity; side grooves are slidably connected to the inner walls of the second cavity; a cavity is formed on one end of the third base plate, and side grooves are slidably connected to the inner walls of the third cavity; and the middle of the sides of the insert plates one, two, and three are provided with... Each position is fixedly connected to a slider, and a return spring is fixedly connected to one end of each slider. A limit rod is fixedly connected to the inner sidewall of one end of each side groove 2 and side groove 3. A cavity 4 is opened on the other sidewall of the base plate 4. When the insert plate 1 moves to the right, the insert plate 1 pushes the insert plate 2 and the insert plate 3 to move to the right, so that the insert plate 1 is inserted into the base plate 2, the insert plate 2 is inserted into the base plate 3, and the insert plate 3 is inserted into the base plate 4. The slider is driven to move to the left by the return spring, and the leftward movement position of the insert plate 2 and the insert plate 3 is limited by the limit rod to prevent the other end of the insert plate 2 from being exposed on the base plate 2.

[0008] Furthermore, the base plate has through slots on both outer side walls, a shaft is rotatably inserted into the middle of the insert plate, and clamps are fixed to both ends of the shaft. Stops are fixed to both sides of the base plate at one end of the through slot. Moving the shaft causes the insert plate to move to the right, thereby causing the clamps to interfere with the stopes and preventing the insert plate from retracting, thus limiting the position of the insert plate.

[0009] Furthermore, magnetic blocks are embedded and fixedly connected to the bottom surfaces of the base plates 1, 2, 3, and 4, and the top surfaces of the base plates 2 and 3. The magnetic blocks on the bottom surface of the base plate 1 attract each other, the magnetic blocks on the bottom surface of the base plate 2 attract each other, the magnetic blocks on the bottom surface of the base plate 3 attract each other, and the magnetic blocks on the top surface of the base plate 2 attract each other, thereby maintaining the M-shaped shape of the base plates 1, 2, 3, and 4 after folding.

[0010] Furthermore, the connecting module includes an arc rod, one end of which is fixedly connected to the top side of the outer wall of the fork, and the other end of which is fixedly connected to a torsion rail. A slider is fixedly connected to the bottom outer wall of the handlebar, and the slider is slidably connected to the torsion rail. A locking block is fixedly connected to the bottom outer wall of the handlebar, and a retaining sleeve is rotatably connected to the other side of the outer wall of the sleeve. The torsion rail and the fork are integrated by means of the arc rod. The spiral shape of the torsion rail allows the handlebar to deflect downwards. The handlebar slides along the torsion rail via the slider. The torsion rail allows the handlebar to move laterally to one side while deflecting downwards, thus moving the handlebar to a position above the position between the front and rear wheels. This ensures that the handlebar is centered after folding, rather than still being directly above the front wheel, making the movement of the entire unit more coordinated when the handlebar is pulled.

[0011] Furthermore, a second connecting rod is fixedly connected to the outer wall of the connecting plate, and a pin is slidably inserted into one end of the second connecting rod. A first connecting rod is fixedly connected to one side of the bottom end of the outer wall of the handle. The first connecting rod and the second connecting rod are inserted together by the pin, thereby limiting the position of the handle.

[0012] Furthermore, the axes of both the rear wheel and the front wheel are located below the base plate, which makes it easier for the axes of the rear wheel and the front wheel to be on the same straight line after folding.

[0013] The beneficial effects of this invention are: 1. Through the setting of the support components, when it is necessary to carry and fold, it folds into an M-shape with base plates one, two, three, and four. The bottom surface of base plate one is attached to the bottom surface of base plate two, the top surface of base plate two is attached to the top surface of base plate three, and the bottom surface of base plate three is attached to the bottom surface of base plate four. This makes the front and rear wheels staggered and coaxial, disengaging the handlebar from the front fork, deflecting the handlebar downward, and limiting the handlebar to achieve overall folding. When folded, the whole thing is close to a suitcase shape. When moving, the front and rear wheels are on the ground. Pulling the handlebar propels the whole thing forward, making it easy to drag on the ground. It is convenient to carry and transport. Moreover, with two wheels on the ground, compared to the two wheels being suspended in the air when carrying from above, it is less likely to scratch other pedestrians, which is more convenient. 2. By setting the connecting module, the handlebar is deflected downwards. The handlebar slides along the torsion rail via the slider. The torsion rail causes the handlebar to move laterally to one side while deflecting downwards, thus moving the handlebar above the position between the front and rear wheels. This ensures that the handlebar is centered after folding, instead of still being directly above the front wheel, making the movement of the whole unit more coordinated when pulling the handlebar.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-10As shown, an inflatable hydrogen fuel cell electric skateboard includes a support assembly 100. The support assembly 100 includes a base plate 110, a base plate 120 rotatably connected to one end of the base plate 110, a base plate 130 rotatably connected to one end of the base plate 120, a base plate 140 rotatably connected to one end of the base plate 130, and a rear wheel 160 mounted on the other end of the base plate 110. The rotation axis between the base plate 110 and the base plate 120 is located on the bottom side of the base plate 110, and the rotation axis between the base plate 120 and the base plate 130 is located at the other end of the base plate 120. On the top side, the rotation shaft between base plate three 130 and base plate four 140 is located on the bottom side of one end of base plate three 130. A battery box 150 is fixedly connected to the top surface of base plate four 140. A control component 200 is provided at one end of base plate four 140. The control component 200 includes a connecting plate 230. A sleeve 231 is fixedly connected to one end of the connecting plate 230. A front fork 240 is rotatably connected to the inner wall of the sleeve 231. A front wheel 260 is installed at the bottom end of the front fork 240. The other end of the connecting plate 230 is fixedly connected to one end of base plate four 140. A handlebar 210 is provided above the top of the front fork 240. The bottom end of the handlebar 210 has a gas tank cavity 220, and a gas tank is fixed to the inner wall of the gas tank cavity 220. The gas tank is provided with an inflation port and an output end. A hose connects the output end of the gas tank to the air inlet of the battery box 150. A connecting module 250 is connected between the bottom end of the handlebar 210 and the top end of the front fork 240. The battery box 150 is used to drive the front wheel 260. A hub motor is installed in the front wheel 260. The gas tank supplies hydrogen to the battery box 150. The battery box 150 consumes hydrogen to generate electrical energy to drive the front wheel 260 to rotate, thus moving forward. When it needs to be folded for carrying, it folds into an M-shape. The system comprises four stacked base plates: base plate 110, base plate 220, base plate 3130, and base plate 4140. The bottom surface of base plate 110 is attached to the bottom surface of base plate 220, the top surface of base plate 220 is attached to the top surface of base plate 3130, and the bottom surface of base plate 3130 is attached to the bottom surface of base plate 4140. This arrangement causes the front wheel 260 and rear wheel 160 to be staggered and coaxial. The handlebar 210 is disengaged from the front fork 240, and the handlebar 210 is deflected downwards. Through the connection module 250, the handlebar 210 is simultaneously deflected downwards and moved laterally to one side, thus allowing the handlebar 210 to... Move it above the position between the front wheel 260 and the rear wheel 160, and limit the handlebar 210 to achieve overall folding. When moving, the front wheel 260 and the rear wheel 160 are on the ground. Pull the handlebar 210 to drive the whole forward, which is convenient for carrying and transporting. When placed, the top of the front fork 240 is in contact with the ground. Together with the front wheel 260 and the rear wheel 160, it can be placed upright, which is more convenient for carrying and use.

[0019] One end of base plate 2 120, both ends of base plate 3 130, and the other end of base plate 4 140 are all inclined, and the inclination angles of each inclined edge are the same. This makes base plate 2 120, base plate 3 130, and base plate 4 140 form an N-shape after folding. The side of base plate 2 120 is parallel to and offset from the side of base plate 4 140, so that the front wheel 260 and the rear wheel 160 are connected by a shaft and offset from each other after folding. One end of base plate 110 has a cavity 111, and the inner wall of cavity 111 is slidably connected to an insert plate 117. The inner walls of both sides of cavity 111 are slidably connected to side grooves 112. One end of base plate 2 120 has a cavity 2 121, and the inner wall of cavity 2 121 is slidably connected to... There is a second insert plate 124. The inner walls of both sides of the cavity 121 are slidably connected to side grooves 122. One end of the base plate 130 has a cavity 131, and the inner walls of both sides of the cavity 131 have side grooves 132. Slider blocks 118 are fixedly connected to the middle positions of both sides of the insert plates 117, 124, and 133. One end of the slider 118 is fixedly connected to a return spring 119. Limit rods 123 are fixedly connected to the inner walls of one end of the side grooves 122 and 132. The other end of the base plate 140 has a cavity 141. When the insert plate 117 moves to the right, it pushes the insert plates 124 and 133 to move to the right, causing the insert plate 117 to connect with the base plate 120. Insertion plate 2 124 is inserted into base plate 3 130, and insertion plate 3 133 is inserted into base plate 4 140. The slider 118 is driven to move to the left by the reset spring 119, and the leftward movement position of insertion plate 2 124 and insertion plate 3 133 is limited by the limit rod 123 to prevent the other end of insertion plate 2 124 from being exposed to base plate 2 120.

[0020] Both outer side walls of the base plate 110 have through slots 113. A shaft 114 is rotatably inserted into the middle of the insert plate 117. Both ends of the shaft 114 are fixedly connected to clamps 115. Both outer side walls of the base plate 110 are fixedly connected to stops 116 at one end of the through slots 113. Moving the shaft 114 causes the insert plate 117 to move to the right, thereby causing the clamps 115 and stops 116 to interfere, preventing the insert plate 117 from retracting, thus limiting the position of the insert plate 117. (Base plate 110, base plate 2, base plate 120, base plate 3, base plate 130) Magnetic blocks 170 are embedded and fixed on the bottom surface of base plate 140 and the top surfaces of base plate 2 120 and base plate 3 130. Magnetic blocks 170 on the bottom surface of base plate 110 and base plate 2 120 attract each other. Magnetic blocks 170 on the bottom surface of base plate 3 130 and base plate 4 140 attract each other. Magnetic blocks 170 on the top surface of base plate 2 120 and base plate 3 130 attract each other. Thus, after folding, the M-shaped shape of base plate 110, base plate 2 120, base plate 3 130 and base plate 4 140 is maintained.

[0021] The connecting module 250 includes an arc rod 251. One end of the arc rod 251 is fixedly connected to the top of the outer side wall of the fork 240, and the other end of the arc rod 251 is fixedly connected to a torsion rail 252. A slider 253 is fixedly connected to the outer side wall of the bottom end of the handlebar 210, and the slider 253 is slidably connected to the torsion rail 252. A locking block 254 is fixedly connected to the outer side wall of the bottom end of the handlebar 210, and a retaining sleeve 255 is rotatably connected to the other side of the outer side wall of the sleeve 231. The torsion rail 252 and the fork 240 are connected as one unit by the arc rod 251. The spiral shape of the torsion rail 252 causes the handlebar 210 to deflect downwards. The handlebar 210 slides along the torsion rail 252 via the slider 253. The torsion rail 252 causes the handlebar 210 to move laterally to one side while deflecting downwards, thereby allowing the handlebar 210 to... The handlebar 210 is moved to a position above the area between the front wheel 260 and the rear wheel 160, so that the folded handlebar 210 is centered instead of still being directly above the front wheel 260. This makes the movement of the entire unit more coordinated when pulling the handlebar 210. A connecting rod 257 is fixedly connected to the outer wall of the connecting plate 230. A pin 258 is slidably inserted into one end of the connecting rod 257. A connecting rod 256 is fixedly connected to one side of the bottom of the outer wall of the handlebar 210. The connecting rod 256 and the connecting rod 257 are inserted together by the pin 258, thereby limiting the position of the handlebar 210. The axes of the rear wheel 160 and the front wheel 260 are both located below the base plate 110, so that the axes of the rear wheel 160 and the front wheel 260 are on the same straight line after folding.

[0022] Working principle: During use, hydrogen gas is supplied to the battery box 150 from the gas tank. The battery box 150 consumes hydrogen gas to generate electrical energy to drive the front wheel 260 to rotate, thus moving forward. When folding is required, slide the axle 114 to the right, causing the locking piece 115 to disengage from the stop block 116. Rotate the locking piece 115 to change from a vertical to a horizontal position, releasing the axle 114. The return spring 119 drives the slider 118 to move to the left, causing the first insertion plate 117, the second insertion plate 124, and the third insertion plate 133 to move to the left. The first insertion plate 117 completely retracts into the first cavity 111, the second insertion plate 124 retracts into the second cavity 121, and the third insertion plate 133 retracts into the third cavity 131, forming an M-shaped folding bottom plate 110, the second insertion plate 120, the third insertion plate 130, and the fourth insertion plate 140. The bottom surface of base plate 110 is in contact with the bottom surface of base plate 2120, the top surface of base plate 2120 is in contact with the top surface of base plate 3130, and the bottom surface of base plate 3130 is in contact with the bottom surface of base plate 4140. Through the setting of magnetic blocks 170, the two surfaces in contact are attracted and fixed by corresponding magnetic blocks 170, thus maintaining an M-shaped fold between base plate 110, base plate 2120, base plate 3130, and base plate 4140. At this time, the front wheel 260 and the rear wheel 160 are staggered and coaxial. Moving the sleeve 255 disengages the sleeve 255 from the locking block 254, causing the handlebar 210 to deflect downwards. The handlebar 210 slides along the torsion rail 252 via the slider 253. Through the setting of the torsion rail 252, the handlebar 210 moves laterally to one side while deflecting downwards, thus allowing the handlebar 210 to... Move it above the position between the front wheel 260 and the rear wheel 160, and connect the connecting rod 256 and the connecting rod 257 together through the pin 258, thereby limiting the handlebar 210 and realizing the overall folding. When moving, the front wheel 260 and the rear wheel 160 are on the ground. Pull the handlebar 210 to drive the whole forward, which is convenient for carrying and transporting. When placed, the top of the front fork 240 is in contact with the ground. At the same time, with the front wheel 260 and the rear wheel 160, it can be placed upright, which is more convenient for carrying and use. When you need to unfold it, simply reverse the folding order.
