In this embodiment, the housing 1 includes a case body 1-1 and a case cover 1-2, where the case body 1-1 and the case cover 1-2 are detachably and fixedly connected or integrally and fixedly connected; the inner cavity of the box body 1-1 is provided with a mounting groove 1-11 for mounting the electric control lock body 5-2 and a mounting cavity 1-12 for mounting the rotating plate 3, the bottom of the mounting groove 1-11 is provided with an opening 1-13 for penetrating out the magnetic suction rod 5-1 of the electric control lock, the opening 1-13 is communicated with the mounting cavity 1-12, and the blocking block 4 is fixed on the inner side surface of the box cover 1-2.

Referring to fig. 2, 7 and 8, in this embodiment, the bottom 2-1 of the lock rod is a plane, the head 2-2 of the lock rod is a semicircle, and a telescopic spring 9 is disposed at the bottom 2-1 of the lock rod, the bottom end of the telescopic spring 9 is fixedly connected with the bottom of the lock rod positioning slot 3-1, and the top end of the telescopic spring 9 is fixedly connected with the bottom 2-1 of the lock rod.

Because most of the locks of the helmets used by the users of the electric vehicle are a Japanese-shaped buckle and a multi-section helical-tooth buckle (at least 2 sections of helical teeth are adopted, such as three sections of buckles, five sections of buckles, seven sections of buckles, ten sections of buckles and the like which are commercially available at present), in order to realize that the helmet anti-theft device can be suitable for the lock catch connection of most helmets used for the electric vehicle, in the embodiment, the rod body 2-3 of the lock rod is a cylinder, and the outer diameter sizes of the head 2-2 of the lock rod and the rod body 2-3 of the lock rod are matched with the opening of the Japanese-shaped eye-splice 10 (shown in the combination of fig. 11 and 13), and the so-called matching is that the outer diameter sizes of the head 2-2 of the lock rod and the rod body 2-3 of the lock rod can ensure that the opening of the conventional Japanese-shaped eye-splice 10 can be easily sleeved into and separated from the lock rod 2. In addition, referring to fig. 8, 16 and 17, in this embodiment, a fixing post 2-4 capable of being used for hooking and fixing the helical tooth 11-1 on the multi-section helical tooth-shaped eye-splice 11 is further protruding on the head 2-2 of the lock rod, the fixing post 2-4 is protruding on the inner side of the head 2-2 of the lock rod, an inward arc guide angle 2-41 is provided on the outer top of the fixing post 2-4, and an outward arc guide angle 2-42 is provided on the inner top of the fixing post 2-4, so that the design can enable the lock rod 2 to be simultaneously suitable for fixing the multi-section helical tooth-shaped eye-splice 11, thereby enabling the helmet anti-theft device of the present application to have good versatility and wide application value.

Referring to fig. 12 and 15 again, in this embodiment, the opening width of the U-shaped opening 3-2 is greater than or equal to (preferably slightly greater than) the maximum horizontal distance for the turning plate 3 to deflect rightward, so as to ensure that in the power-off state of the electric vehicle (when the electric control lock 5 is in the power-off state, the magnetic attraction rod 5-1 of the electric control lock is inserted into the U-shaped opening 3-2), when the helmet buckle is inserted into the buckle insertion hole 8, under the action of inward pushing force, the magnetic attraction rod 5-1 of the electric control lock can still be positioned in the U-shaped opening 3-2 along with the turning plate 3 to deflect rightward, and the turning plate 3 is not blocked from deflecting rightward.

Referring to fig. 14 and 18 again, in this embodiment, the opening depth of the U-shaped opening 3-2 is smaller than or equal to (preferably slightly smaller than) the maximum contraction distance of the magnetic rod 5-1 of the electric control lock, so as to ensure that the magnetic rod 5-1 of the electric control lock can be contracted and lifted out of the U-shaped opening 3-2 in the power-on state of the electric vehicle (when the electric control lock 5 is in the power-on state), thereby releasing the constraint of leftward deflection of the rotating plate 3, and enabling the rotating plate 3 to deflect leftward when the helmet buckle is pulled outwards by the buckle jack 8, so as to facilitate the separation and unlocking between the helmet buckle and the lock rod 2.

Referring again to FIG. 6, the length dimension of the hypotenuse face 4-1 of the stop block 4 is equal to the sum of the radius dimension of the scallop groove and the width dimension of the flange, and the width dimension of the hypotenuse face 4-1 of the stop block 4 is equal to the depth dimension of the scallop groove. This design ensures that the blocking piece 4 can resist the bottom of the rotating plate 3 when the rotating plate 3 deflects to the right (as shown in fig. 12), and ensures that the top of the blocking piece 4 can enter the sector groove 3-3 of the rotating plate 3 when the rotating plate 3 deflects to the left, so that the leftward deflection of the rotating plate 3 is not blocked (as shown in fig. 14).

In this embodiment, the electric control lock 5 is a small-sized round bar electric control lock with 12V dc working voltage for unlocking and locking by power-on/off, for example: commercially available OTL-DS03 type round bar electric control lock. The structure and the working principle of the electric control lock 5 are known technologies, and are not described herein.

Please refer to fig. 9 and 10 again: the anti-theft device for the helmet further comprises a mounting bracket 12, wherein the mounting bracket 12 comprises a connecting part A12-1 connected with the shell 1 and a connecting part B12-2 connected with the handlebar tube 13, the connecting part A12-1 is detachably fixedly connected or integrally fixedly connected with the back surface of the shell 1, and the connecting part B12-2 is detachably fixedly connected or integrally fixedly connected with the handlebar tube 13.

As a preferred solution, the helmet anti-theft device of the present utility model is invisible installed inside an outer shell (not shown in the figure) of an electric vehicle, and only the buckle insertion hole 8 is embedded in the outer surface of the outer shell (not shown in the figure), so that the design can further improve the anti-theft performance, does not affect the appearance of the whole electric vehicle, and can simplify the manufacturing requirements of the helmet anti-theft device, for example: under the design, the box body 1-1 and the box cover 1-2 can be detachably and fixedly connected, so that the assembly operation of the helmet anti-theft device is convenient, and accessories in the helmet anti-theft device can be conveniently maintained and replaced in the later period; in this design, the connection part A12-1 and the back of the housing 1 are preferably connected by a detachable fixing connection, and the connection part B12-2 and the handle bar tube 13 may be connected by a detachable fixing connection or an integral fixing connection.

Because in the existing electric vehicle design, in order to achieve attractive appearance of an integral vehicle model, tidy wiring and safety of necessary components, the power supply wiring and the important components are designed in a concealed installation mode, the application only needs to select a proper installation position on an outer shell around an existing electric vehicle handle pipe, an opening matched with a buckle jack 8 is reserved or formed in the electric vehicle outer shell at the installation position, and an inner cavity of the electric vehicle outer shell at the installation position can accommodate the lower shell 1 to realize concealed installation of the helmet anti-theft device.

In addition, fig. 11 to 14 show the process of locking and unlocking the helmet by adopting the helmet anti-theft device provided by the utility model when the helmet buckle is a Chinese character 'ri' shaped buckle, and the specific working process is as follows:

because the continuous power-on time of the electric control lock 5 during unlocking is usually less than 10 seconds, the time is very short, although the electric control lock products capable of being electrified for a long time exist in the prior art, the products are generally unnecessary and unnecessary, and because the electric control lock products electrified for a long time are used, the cost is very high, the service life is short, and faults are easy to occur; therefore, the electric control lock 5 used in the present application is preferably a common electric control lock product, and does not require continuous energization for a long time; that is, the magnetic attraction rod 5-1 of the electric control lock in the application only needs to be in an electrified and contracted state when being unlocked, namely: the magnetic attraction rod 5-1 of the electric control lock is only in a state of being contracted and lifted out of the U-shaped opening 3-2 when being unlocked, and the magnetic attraction rod 5-1 of the electric control lock is released and inserted into the U-shaped opening 3-2 in the rest conditions. Therefore, after the user of the electric vehicle rides to the destination, no matter whether the electric vehicle power supply is in a power-off state or not, the helmet anti-theft device provided by the utility model is in the initial state characteristics shown in fig. 11:

1-0) the telescopic spring 9 at the bottom of the lock rod is in an original stretching state;

2-0) the magnetic suction rod 5-1 of the electric control lock is released and inserted into the U-shaped opening 3-2 and is positioned at the right limit position of the U-shaped opening 3-2;

3-0) the rotating plate 3 is in an undeflected original state;

4-0) the torsion spring 7 is also in the original state;

when the Chinese character 'ri' shaped eye-splice 10 fixed on the helmet strap is inserted into the buckle jack 8 and touches the head 2-2 of the lock rod, the Chinese character 'ri' shaped eye-splice 10 will exert downward pressure on the head 2-2 of the lock rod along with inward pushing, so that the telescopic spring 9 is compressed and the rotating plate 3 deflects towards the pushing direction (i.e. the right direction in fig. 12) under the action of the inward pushing force; because the opening width of the U-shaped opening 3-2 is larger than or equal to (preferably slightly larger than) the maximum horizontal distance for the turning plate 3 to deflect rightwards, the magnetic suction rod 5-1 of the electric control lock can still be positioned in the U-shaped opening 3-2 along with the turning plate 3 to deflect rightwards, and the turning plate 3 is not blocked from deflecting rightwards; in addition, since the lower part of the rotating plate 3 is rotationally connected with the housing 1 through the pin shaft 6, the right fixing arm 7-1 of the torsion spring sleeved on the pin shaft 6 is fixedly connected with the flange 3-4 of the fan-shaped groove 3-3, and the left fixing arm 7-2 of the torsion spring is fixedly connected with the bevel edge surface 4-1 of the blocking block 4 fixed on the inner side surface of the box cover 1-2, when the rotating plate 3 deflects rightward, the torsion spring 7 is in a stretched state, so that the state characteristics of the locking process as shown in fig. 12 can be generated:

1-1) the telescopic spring 9 positioned at the bottom of the lock rod is in a compressed state;

2-1) the magnetic suction rod 5-1 of the electric control lock is still inserted into the U-shaped opening 3-2, but the position in the U-shaped opening 3-2 is shifted leftwards;

3-1) the rotating plate 3 deflects rightward, and the blocking block 4 plays a role in resisting the bottom of the rotating plate 3;

4-1) the torsion spring 7 is in a stretched state;

the outer diameter dimensions of the head 2-2 of the lock rod and the shaft 2-3 of the lock rod are designed to be matched with the opening of the japanese-shaped eye-splice 10, that is, the outer diameter dimensions of the head 2-2 of the lock rod and the shaft 2-3 of the lock rod can ensure that the opening of the existing japanese-shaped eye-splice 10 can be easily sleeved into and separated from the lock rod 2, in addition, the head 2-2 of the lock rod is designed to be hemispherical, and the outer top of the fixed column 2-4 is provided with an inward arc lead angle 2-41, so that the head 2-2 of the lock rod can easily penetrate out of the opening of the japanese-shaped eye-splice 10 and is not subjected to downward acting force any more along with inward pushing of the japanese-shaped eye-splice 10, so that the opening of the japanese-shaped eye-splice 10 is sleeved into the shaft 2-3 of the lock rod, and the rotating plate 3 is not subjected to rightward pushing force any more, so that the rotating plate 3 is reset to an initial undeflected state under the restoring force of the torsion spring 7, and thus the locked state shown in fig. 13 is generated.

1-2) the telescopic spring 9 at the bottom of the lock rod is in an original stretching state;

2-2) the magnetic suction rod 5-1 of the electric control lock is inserted into the U-shaped opening 3-2 and is positioned at the right limit position of the U-shaped opening 3-2;

3-2) the rotating plate 3 is in an undeflected original state;

4-2) the torsion spring 7 is also in the original state;

when the electric bicycle is ready to be ridden, the electric bicycle power supply is started by the electric bicycle key, the electric control lock 5 in the helmet anti-theft device can be electrified, so that the magnetic attraction rod 5-1 of the electric control lock is contracted and lifted, and the opening depth H of the U-shaped opening 3-2 is smaller than or equal to (preferably smaller than) the maximum contraction distance of the magnetic attraction rod 5-1 of the electric control lock, so that the magnetic attraction rod 5-1 of the electric control lock is contracted and lifted and then separated from the U-shaped opening 3-2, and the constraint on left deflection of the rotating plate 3 is released, and therefore, as the helmet buckle is pulled outwards, the rotating plate 3 is driven to deflect leftwards, the Chinese character 'ri' shaped eye-splice 10 is displaced from the rod body 2-3 of the lock rod to the head 2-2 of the lock rod, as the pulling outwards is continued, the Chinese character 'ri' shaped eye-splice 10 generates a downward pressure effect on the head 2-2 of the lock rod, and the telescopic spring 9 is in a compressed state, so that the state characteristic of an unlocking process as shown in fig. 14 is generated:

1-3) the telescopic spring 9 positioned at the bottom of the lock rod is in a compressed state;

2-3) the magnetic suction rod 5-1 of the electric control lock is lifted to be separated from the U-shaped opening 3-2;

3-3) the rotating plate 3 deflects leftwards, and the top of the blocking block 4 enters the sector groove 3-3 of the rotating plate 3;

4-3) the torsion spring 7 is in a compressed state;

with further outward pulling and under the guiding action of the outward arc guide angles 2-42, the Chinese character 'ri' -shaped eye-splice 10 is easily separated from the lock rod 2 so as to be unlocked and taken out;

once the zigzag buckle 10 is unlocked and taken out, the lock lever 2 is reset under the restoring force of the extension spring 9, and the rotating plate 3 is reset under the restoring force of the torsion spring 7, thereby restoring to the original state feature shown in fig. 11.

Fig. 15 to 19 show the process of locking and unlocking the helmet by adopting the helmet anti-theft device provided by the utility model when the helmet buckle is a multi-section oblique tooth-shaped eye-splice, and the specific working process is as follows:

when the multi-section helical gear buckle 11 fixed on the helmet belt is inserted into the buckle jack 8 and touches the head 2-2 of the lock rod, the multi-section helical gear buckle 11 will exert downward pressure on the head 2-2 of the lock rod along with inward pushing, so that the telescopic spring 9 is compressed and the rotating plate 3 deflects towards the pushing direction (i.e. the right direction in fig. 15) simultaneously, and the state characteristics of the locking process shown in fig. 15 are generated:

1-1') the telescopic spring 9 at the bottom of the lock rod is in a compressed state;

2-1') the magnetic suction rod 5-1 of the electric control lock is still inserted into the U-shaped opening 3-2, but the position in the U-shaped opening 3-2 is shifted leftwards;

3-1') the rotating plate 3 deflects rightward, and the blocking block 4 plays a role in blocking the bottom of the rotating plate 3;

4-1') the torsion spring 7 is in a stretched state;

as the multi-section helical gear shaped eye-splice 11 is pushed further inwards, the helical gear 11-1 will pass over the top of the fixed column 2-4 under the guiding action of the inward arc guide angle 2-41 to hook the fixed column 2-4 (please refer to fig. 16 and 17), so that the multi-section helical gear shaped eye-splice 11 is hooked and fixed; and thus the inward pushing force has disappeared, the rotating plate 3 is restored to the original undeflected state by the restoring force of the torsion spring 7, thereby generating the locked state feature shown in fig. 16:

1-2') the telescopic spring 9 at the bottom of the lock rod is still in a compressed state;

2-2') the magnetic suction rod 5-1 of the electric control lock is inserted into the U-shaped opening 3-2 and is positioned at the right limit position of the U-shaped opening 3-2;

3-2') the rotating plate 3 is in an undeflected original state;

4-') the torsion spring 7 is also in the original state;
