Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention.

With the implementation of the new specifications of electric bicycles and the requirement that the electric bicycle needs to wear a helmet, the helmet becomes a necessary article for people to go out, and the electric bicycle under the new specifications has no space for placing the helmet, so that the helmet is difficult to store, and the helmet is difficult to store; there is a need to design a helmet lock suitable for an electric vehicle under new regulations.

Referring to fig. 1, a schematic view of an exemplary helmet and a helmet lock when not engaged with each other is shown, the invention designs a helmet having an anti-theft function, and specifically, a structure engaged with the helmet lock is arranged on the surface of a helmet shell of the helmet close to a back head scoop, so as to achieve an anti-theft effect.

Example 1

Referring to fig. 2 to 4, the helmet includes a helmet shell 1, and is characterized in that: the surface of helmet shell is equipped with a locking groove 10 at least, locking groove 10 link up with helmet shell's lower terminal surface, during the use, helmet from the top down motion, the locking of helmet lock is protruding to be inserted into the locking inslot of helmet, after the helmet passes through the locking groove with the helmet lock and is connected, the helmet can only follow the length direction motion in locking groove, the helmet can only move at the length direction in locking groove promptly, unable length direction along the locking groove takes place to rotate and perpendicular length direction's removal, still including the locking structure 2 of restriction helmet along locking groove length direction motion, locking structure is used for and helmet lock cooperation, the motion of length direction along the locking groove is restricted to the helmet, reach the effect of locking theftproof.

In the embodiment, the surface of the helmet shell is provided with two locking grooves 10, and the two locking grooves are symmetrically arranged by taking the locking structure as a center; the locking groove 10 comprises a guide groove 101 arranged on the surface of the helmet shell and a limiting groove 102 communicated with the guide groove 101, the limiting groove enables the helmet to move only along the guide groove, the limiting groove further limits the freedom degree of the helmet, and the helmet cannot rotate around the locking groove and move in the vertical length direction.

Furthermore, the limiting groove 102 is a groove body arranged at an included angle with the guide groove and communicated with the guide groove, in this embodiment, a limiting groove is arranged on one side of the guide groove, the limiting groove and the guide groove are arranged at an included angle, so that the intersection of the limiting groove and the guide groove is ensured, and the preferred limiting groove is perpendicular to the guide groove; according to actual need, can also all set up the restriction groove in the both sides of guide way, when cooperating with the helmet lock, both joint strength are better, are difficult to by the violence destruction, have more reliable theftproof effect.

The locking structure 2 is a locking hole on the helmet shell, a locking rod in the helmet lock can be inserted into the locking hole to lock the helmet along the movement of the locking groove, and the anti-theft effect is achieved.

Example 2

Referring to fig. 5, the helmet includes a helmet shell 1, and is characterized in that: the surface of helmet shell is equipped with a locking groove 10 at least, locking groove 10 link up with helmet shell's lower terminal surface, during the use, helmet from the top down motion, the locking of helmet lock is protruding to be inserted into the locking inslot of helmet, after the helmet passes through the locking groove with the helmet lock and is connected, the helmet can only follow the length direction motion in locking groove, the helmet can only move at the length direction in locking groove promptly, unable length direction along the locking groove takes place to rotate and perpendicular length direction's removal, still including the locking structure 2 of restriction helmet along locking groove length direction motion, locking structure is used for and helmet lock cooperation, the motion of length direction along the locking groove is restricted to the helmet, reach the effect of locking theftproof.

The limiting groove 102 in this embodiment is a cylindrical groove body communicated with the guide groove, and further, the diameter of the cylindrical groove body is larger than the width of the guide groove, so that the structure embedded in the locking groove cannot be separated from the guide groove.

Example 3

The difference from embodiment 2 is that the structure of the locking groove of this embodiment is changed, as shown in fig. 6, the limiting groove 102 is a variable cross-section groove body communicated with the guide groove, and the width of the limiting groove far away from the guide groove is greater than that of the limiting groove near the guide groove, so as to ensure that the structure embedded in the locking groove cannot be separated from the guide groove.

Example 4

Referring to fig. 7, the helmet includes a helmet shell 1, and is characterized in that: the surface of helmet shell is equipped with a locking groove 10 at least, locking groove 10 link up with helmet shell's lower terminal surface, during the use, helmet from the top down motion, the locking of helmet lock is protruding to be inserted into the locking inslot of helmet, after the helmet passes through the locking groove with the helmet lock and is connected, the helmet can only follow the length direction motion in locking groove, the helmet can only move at the length direction in locking groove promptly, unable length direction along the locking groove takes place to rotate and perpendicular length direction's removal, still including the locking structure 2 of restriction helmet along locking groove length direction motion, locking structure is used for and helmet lock cooperation, the motion of length direction along the locking groove is restricted to the helmet, reach the effect of locking theftproof.

In the embodiment, a locking groove is arranged, and the locking structure vertically penetrates through the locking groove; the structure is simpler, but the structural strength of one locking groove may be relatively weak and there is a possibility of being violently broken, compared to the three embodiments described above.

To sum up, the utility model discloses following beneficial effect has:
