DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. Embodiment one

[0029] Please refer to Figures 1-3, by setting the battery pack 7 under the seat cushion in the middle of the vehicle body 1, and by setting the motor 8 that drives the tire rotation in the bottom of the vehicle body 1 to promote the vehicle body 1 forward, the front of the vehicle body 1 is provided with the control handle 4 that controls the front wheel steering and the motor 8 driving, and the display screen 3 for displaying the riding state is set in the front of the vehicle body 1, and the on-off switch 5 for starting the vehicle is set on the vehicle body 1, and the placement slot 100 is opened in the front of the vehicle body 1 and below the display screen 3, and the placement rod 19 that is adapted to the placement slot 100 is set in the bottom of the safety helmet 2, the shape of the placement rod 19 is cylindrical, the angle between the center line of the placement slot 100 and the bottom of the vehicle body 1 is thirty to seventy-five degrees, so that the safety helmet 2 is directly inserted into the placement slot 100 during taking and placing, so that it is easy to take and place, reduces the storage space occupied by the safety helmet 2, and makes it easy for the rider to carry, and the placement slot 100 is inclined to place, so that the outside of the safety helmet 2 is on the outside, and the inner wall of the safety helmet 2 is downward and towards the vehicle body 1, and the rain and dust on the outside will directly fall on the outside of the safety helmet 2 when falling from above, so that the inside of the safety helmet 2 will not be contaminated, so that the rider will not be difficult to wear because the safety helmet 2 is too dirty during wearing, and the placement rod 19 set in the bottom of the safety helmet 2 will cause the center of gravity of the safety helmet 2 to be relatively far away from the direction of the placement rod 19, so that after the safety helmet 2 is inserted into the placement slot 100, the safety helmet 2 will always have an inside-down direction due to the shift of its own center of gravity, which ensures that the safety helmet 2 will automatically change to a state of protecting the inside without manual intervention after being placed. Example two

[0030] Based on the basis of example one, please refer to Figure 2 and Figure 3 , by setting the adjusting magnetic block 18 in the bottom of the placement slot 100, and fixing the coil 9 outside the placement slot 100 on the inner wall of the vehicle body 1, and the coil 9 is on one side of the adjusting magnetic block 18, and the placement rod 19 is made of metal rod, which ensures that the coil 9 generates a magnetic force repelling the adjusting magnetic block 18 by being electrified during the starting process of the on-off switch 5, and the placement rod 19 is a metal rod that can concentrate magnetic force, so that the placement rod 19 concentrates the magnetic force generated by the coil 9 after being inserted into the inside of the coil 9, which promotes the repelling magnetic force between the placement rod 19 and the adjusting magnetic block 18, which makes the adjusting magnetic block 18 and the placement rod 19 push the placement rod 19 out of the placement slot 100 under the action of magnetic repulsion, and because there is no place on the vehicle body 1 to place the safety helmet 2, the safety helmet 2 will be pushed out first before the vehicle body 1 needs to be started, forcing the rider to wear the safety helmet 2, which ensures that the rider must wear it during riding because the safety helmet 2 cannot be placed.

[0031] Please refer to Figures 2-4 , by fixing and installing anti-off spring 17 at one end of the adjusting magnetic block 18, and by the elastic force of the anti-off spring 17, the adjusting magnetic block 18 is pushed to the direction of the placement rod 19, the inner wall of the vehicle body 1 and located on one side of the placement rod 19 is hinged with an anti-off pusher 16, the side wall of the adjusting magnetic block 18 is fixedly provided with a guide rod, and by opening a guide groove 160 on the anti-off pusher 16, the top of the guide rod is slid in the guide groove 160 by setting a cylindrical rod, and according to the inclined arrangement of the guide groove 160, when the adjusting magnetic block 18 moves the guide rod to the direction of the placement rod 19, it will make the anti-off pusher 16 move to the direction close to the placement rod 19, and for the same reason, when the adjusting magnetic block 18 moves away from the placement rod 19, the guide rod outside the adjusting magnetic block 18 will make the anti-off pusher 16 deflect away from the placement rod 19 by moving in the guide groove 160, and the inner wall of the anti-off pusher 16 is movably installed with a movable frame 10, and the inner wall of the movable frame 10 is movably installed with a locking top rod 14, and the end of the locking top rod 14 is fixedly installed with an ejection spring 11 in the inner cavity of the movable frame 10, and an anti-off groove 190 is opened on the side wall of the placement rod 19, so that the locking top rod 14 will be pushed in the anti-off groove 190 by the elastic force of the ejection spring 11, so as to ensure that when the on-off switch 5 is started, the placement rod 19 and the adjusting magnetic block 18 will generate repulsive magnetic force, so that the placement rod 19 is separated, and because the adjusting magnetic block 18 is moved to the direction of the placement rod 19 by the elastic force of the anti-off spring 17, the anti-off pusher 16 is forced to deflect to the direction of the placement rod 19, and the locking top rod 14 is blocked by the coil 9 when it moves in the anti-off groove 190, so that the placement rod 19 cannot be pushed out, and because there is still magnetic repulsion force between the placement rod 19 and the adjusting magnetic block 18, the adjusting magnetic block 18 will compress the anti-off spring 17, and when the adjusting magnetic block 18 compresses the anti-off spring 17, the anti-off pusher 16 will deflect away from the placement rod 19, until the locking top rod 14 is separated from the placement rod 19, the placement rod 19 will be magnetized to make the safety helmet 2 separate from the vehicle body 1, and after the whole vehicle is powered off, the locking top rod 14 will always press on the placement rod 19, so that the placement rod 19 cannot be separated from the vehicle body 1 during power-off, ensuring that the safety helmet 2 will not be stolen even during the power-off process of the whole vehicle.

[0032] In the application, the number of movable racks 10 is set to two, both of which are movably installed on the same side of the anti-falling push rack 16, and a detection spring 13 is fixed between the two movable racks 10. Thus, the two movable racks 10 are pushed by the display screen 3, and it is ensured that the movable racks 10 cannot be close to each other. A limiting groove for limiting the movement range of the movable racks 10 is arranged on the side wall of the anti-falling push rack 16, so that the movable racks 10 can only move within the fixed range of the side wall of the anti-falling push rack 16 during actual use. The locking top rods 14 are movably installed in the two movable racks 10, the locking top rods 14 are arc-shaped cylinders with different diameters, and the difference between the diameters of the two locking top rods 14 is three to six times. An electric contact 15 is fixedly installed on one side of the movable rack 10, and a corresponding power receiving contact 150 is arranged on the other side of the movable rack 10. When the locking top rods 14 are in contact with the electric contact 15 and the power receiving contact 150, the circuit is connected. Since there are two electric contacts 15 and power receiving contacts 150, one electric contact 15 and power receiving contact 150 form a group, and the power receiving contact 150 and the electric contact 15 in the group are alternatively arranged on one movable rack 10. Thus, two switches are formed by the two movable racks 10. The electrically isolated parts 140 are arranged on the middle and arc-shaped end of the locking top rod 14. The electrically isolated part 140 at the end ensures that there is no conduction phenomenon during contact with the placing rod 19. When the electrically isolated part 140 passes through the electric contact 15 and the power receiving contact 150, the electric contact 15 and the power receiving contact 150 will not be connected in circuit. The triangular pyramid blocks 191 are fixedly arranged in the anti-falling groove 190 on the side wall of the placing rod 19, and the number of triangular pyramid blocks 191 is at least twelve. The triangular pyramid blocks 191 are arranged at equal angles on the side of the placing rod 19. At the same time, the arc-shaped end of one locking top rod 14 is on the outside top of the triangular pyramid block 191, and the other locking top rod 14 is on the triangular pyramid block 191. At this time, the two electrically isolated parts 140 are in contact with the electric contact 15 and the power receiving contact 150, which ensures that the safety helmet 2 has a certain damping during rotation, avoids the phenomenon that the safety helmet 2 repeatedly rotates due to external wind force, and avoids the phenomenon that the safety helmet 2 is contaminated when it swings. Even if the locking top rod 14 inserted between the triangular pyramid blocks 191 is pushed upward, the electric contact 15 and the power receiving contact 150 will not be connected. Thus, during subsequent use, the user can insert the safety helmet 2 into the placing groove 100 through the placing rod 19. Only when both locking top rods 14 are in the anti-falling groove 190, the electrically isolated parts 140 on the locking top rods 14 will block the electric contact 15 and the power receiving contact 150. The simultaneous disconnection of the two electric contacts 15 and power receiving contacts 150 realizes the disconnection of the whole vehicle. Thus, it is ensured that the whole vehicle can be disconnected only when the safety helmet 2 is placed and located in the external position.Avoid the phenomenon of the safety helmet 2 after riding randomly placed and lost.

[0033] Please see Figure 3 , The alarm switch 12 is fixedly installed on the inner wall of the movable frame 10 between the two movable frames 10, and the alarm bell 6 is fixedly installed on the front of the vehicle body 1. When the alarm switch 12 is connected, the alarm bell 6 connected with the alarm switch 12 will sound, so as to ensure that the safety helmet 2 will sound through the alarm bell 6 for alarm when it is forcibly taken out during placement, warning that the safety helmet 2 is being stolen at this time.

[0034] And a step groove 193 is formed in the inner wall of the placing rod 19, which is communicated with the anti-extraction groove 190, and a disengagement groove 194 is formed in the side wall of the placing rod 19, which ensures that the placing rod 19 and the adjusting magnetic block 18 repel each other when the placing rod 19 is ridden, and when the locking top rod 14 near the adjusting magnetic block 18 passes through the step groove 193, the anti-extraction pusher 16 will be deflected outward and the locking top rod 14 will not be able to pass through the step groove 193, and when the safety helmet 2 is placed downward inside, the disengagement groove 194 will follow downward, and the locking top rod 14 will be blocked by the inner wall of the placing rod 19, so that the locking top rod 14 is not easy to output, and after the two movable frames 10 press the detection spring 13, the alarm switch 12 is connected to make the alarm bell 6 sound, at this time, if the user does not take out the safety helmet 2, the alarm bell 6 will continue to sound, and only after the user rotates the safety helmet 2 by one hundred and eighty degrees, the disengagement groove 194 will be rotated upward, so that the locking top rod 14 will be output from the disengagement groove 194, so that the safety helmet 2 is easy to take out, avoiding the phenomenon that the safety helmet 2 is pushed out by magnetic repulsion between the placing rod 19 and falls to the ground, so that the safety helmet 2 is not clean.

[0035] At the same time, the alarm lamp 300 is arranged in the display screen 3, so as to ensure that the safety helmet 2 will frequently flash in the display screen 3 when it is not taken out during riding, so as to visually remind the rider, and if the vehicle is moved temporarily, the safety helmet 2 can be moved without being pulled out, and at this time, the alarm bell 6 will continue to sound, and the short-term sound will not affect the operator due to the short-term movement of the vehicle.

[0036] Please see Figure 2 , Figure 3 and Figure 5, one of the two blades of the on-off switch 5 is connected with the positive pole of the battery group 7, the on-off switch 5 is a double-blade three-contact switch, the on-off switch 5 has two blades and three contacts, the two blades of the on-off switch 5 move simultaneously, the coil 9 is connected through one contact of the on-off switch 5, and the other end of the coil 9 is connected with the other contact and the other blade of the on-off switch 5, at the same time, the contact of the on-off switch 5 is connected with the alarm switch 12 and the power contact 15 simultaneously, and the alarm switch 12 and the power contact 15 are connected in parallel, since the number of the power contact 15 is two, the two power contacts 15 and the alarm switch 12 are connected in parallel, and the alarm lamp 300 is arranged at one end of the alarm switch 12, and the alarm lamp 300 is connected through the fuse and the negative pole of the battery group 7, and the delay opening switch is connected in parallel on the alarm lamp 300, the timing of the delay opening switch is adjustable, generally set to five to ten seconds, and the alarm bell 6 is connected in series with the delay opening switch, and the power receiving contact 150 connected with the power contact 15 is connected to the negative pole of the battery group 7 through the fuse after the display screen 3, and the control handle 4 and the motor 8 are connected in parallel with the display screen 3, and one end of the control handle 4 is connected with the other contact of the on-off switch 5, so that it can be known that one blade of the on-off switch 5 is connected with the positive pole of the battery group 7, the other blade of the on-off switch 5 is connected with one contact of the on-off switch 5, and the contact is connected with another contact while connecting the coil 9, one end of the coil 9 is connected with the contact, the alarm switch 12 and the power contact 15, and the combination Figure 2 、 Figure 3 and the on-off switch 5 can be known that when the safety helmet 2 is placed on the vehicle body 1, at this time:

[0037] If you want to start moving the vehicle body 1, turn the on-off switch 5, so that the two blades of the on-off switch 5 will be connected respectively Figure 5At the two contacts above, on the one hand, the positive terminal of battery pack 7 is connected to coil 9 via the blade of switch 5 and one contact of switch 5. The other end of coil 9 is connected to switch 5 via the blade of switch 5 and another contact of switch 5. At this time, switch 5 will directly connect control handle 4 and motor 8. Control handle 4 can work by controlling motor 8, and display screen 3 will work at the same time. On the other hand, because one contact of switch 5 is connected, this contact will activate alarm switch 1. 2 and the energizing contact 15 enter the circuit, while the safety helmet 2 is installed on the vehicle body 1 at this time, which causes the energizing contact 15 and the receiving contact 150 to be disconnected when the locking rod 14 is pressed against the anti-detachment groove 190. The alarm switch 12 is disconnected due to the elastic force of the detection spring 13 causing the movable frame 10 to move away, and the coil 9 generates magnetism that repels the adjusting magnetic block 18, which in turn concentrates the magnetism through the placement rod 19, forcing the placement rod 19 to move outward, and the adjusting magnetic block 18 compresses the anti-detachment spring 17, deflecting the anti-detachment push frame 16, and at the release When the release lever 19 moves outward, the locking rod 14 near the adjusting magnet 18 presses against the stepped groove 193. This, in turn, causes the alarm switch 12 to activate due to the outward movement of the release lever 19. At this time, even if the energizing contacts 15 and energizing contacts 150 are connected, it will not affect the operation of the control handle 4 and the motor 8. When the alarm switch 12 is activated, the alarm light 300 will illuminate first. At this time, the rider can rotate the safety helmet 2 180 degrees and remove it based on the warning from the alarm light 300. If the rider does not remove the helmet, the timer on the delayed-on switch will end, causing the alarm bell 6 to remain on. The alarm bell 6 will continuously sound to warn the rider to remove and wear the safety helmet 2. Once the user removes the safety helmet 2, the alarm switch 12 will turn off again. Due to the release of the spring 11, the locking rod 14 will connect the power contact 15 and the power receiving contact 150, allowing them to work together.

[0038] If you have finished cycling, please refer to Figure 5 When the switch 5 is closed, only one blade of the switch 5 will connect to the lowest contact. At this time, the positive terminal of the battery pack 7 can only be connected through the power contact 15 and the power receiving contact 150 via the switch 5 and the coil 9, so that the control handle 4 and the motor 8 are still in working state. Only when the placement rod 19 on the safety helmet 2 is inserted into the placement slot 100, the current direction on the coil 9 changes, causing the coil 9 to attract the placement rod 19 to the adjusting magnetic block 18, making it easier for the placement rod 19 to pass through until the movable frame 10 is fully engaged in the anti-detachment slot 190. At this time, the electrical isolation part 140 disconnects the power contact 15 and the power receiving contact 150, thereby completely disconnecting the control handle 4 and the motor 8, realizing the phenomenon that the whole machine is powered off only after the safety helmet 2 is placed.

[0039] If the safety helmet 2 is stolen, the safety helmet 2 is pulled out, the locking top rod 14 is not compressed, the movable frame 10 is pulled out, the alarm switch 12 is turned on, the alarm switch 12 is turned on, the coil 9 is turned on, the coil 9 is turned off, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil 9 is turned on, the coil
