Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, specifically to a modular and detachable child safety helmet. Background Technology

[0002] A safety helmet is a type of hat with a hard shell, which includes not only safety helmets used to protect against specific dangers or for special scenarios, but also helmets for cycling and other types.

[0003] One type of safety helmet for children typically has a hard shell and detachable goggles. In some commercial settings, to attract children's attention and encourage them to wear the helmets, merchants attach decorative ears such as rabbit ears or unicorn ears to the shell. Currently, these decorative ears are usually fixed or inserted into the outside of the helmet through a simple connecting structure. The former method prevents the structure from being changed according to the child's preferences, while the latter makes it easy for the ear to detach after insertion. Furthermore, when multiple connecting structures are used, unused connecting structures leave exposed holes or rod-like structures on the helmet, which is not aesthetically pleasing. Utility Model Content

[0027] like Figure 1-5 As shown, a modular and detachable child safety helmet includes a helmet shell 1, a connecting pressure plate 2 on the helmet shell 1, a plurality of disassembly units on the connecting pressure plate 2, and a plurality of guide holes 3 on the connecting pressure plate 2. Each disassembly unit corresponds to the position of one of the guide holes 3. At least one guide hole 3 is inserted into a decorative ear 4, and a positioning notch 5 is formed on the decorative ear 4. The disassembly unit includes a stop plate 6 that rotates on the back side of the connecting pressure plate 2. An insert end 7 is formed on the stop plate 6. The disassembly unit also includes a positioning protrusion 8 that is fixed on the connecting pressure plate 2 and located on one side of the stop plate 6. An elastic member 9 is provided between the positioning protrusion 8 and the side of the adjacent stop plate 6 away from the insert end 7. The connecting pressure plate 2 is also equipped with a control unit, which includes a control end 10 that is slidably connected to one side of the connecting pressure plate 2, and a pull rope 11 that is fixed to one side of the stop plate 6. One end of the multiple pull ropes 11 is fixed to the control end 10.

[0028] In this embodiment, by pulling the control end 10 outward, each pull rope 11 changes from slack to taut and is pulled along with one end fixed to the control end 10. When the other end moves, it applies force to the connected stop plate 6, causing the stop plate 6 to rotate around the rotation center, so that the insert 7 inserted into the positioning notch 5 disengages from the positioning notch 5. At this time, the decorative ear 4 can be easily taken out from the corresponding guide hole 3. The decorative ear 4 is set in several types according to the different structures formed on it. Children can insert their favorite decorative ear 4 into their own hat shell 1, thereby realizing a modular disassembly scheme. In this scheme, the insertion and removal of the decorative ear 4 is relatively simple and can be completed by the child. Moreover, after the decorative ear 4 is fixed, it will not be easily removed from the hat shell 1, which improves the stability of the decorative ear 4 after it is fixed.

[0029] like Figure 5 As shown, optionally, a through hole is formed on the blocking plate 6, and a hole-blocking post 12 is slidably connected in the through hole. A disc edge 13 is formed on the hole-blocking post 12, and a spring 14 is sleeved on the outside of the hole-blocking post 12. The two ends of the spring 14 are fixed to the disc edge 13 and one side of the adjacent blocking plate 6, respectively. When one end of the hole-blocking post 12 is flush with the outer end face of the guide hole 3, the spring 14 is in a stretched state, and the outer end face of the hole-blocking post 12 is provided with a rounded corner.

[0030] In this embodiment, if the decorative ear 4 is not inserted into the guide hole 3, the blocking plate 6 will rotate under the action of the elastic member 9 to make the insert 7 pass over the guide hole 3 and align the through hole on the blocking plate 6 with the guide hole 3. When the two are aligned, under the elastic force of the spring 14, one end of the hole-blocking post 12 will move outward, enter the guide hole 3 through the through hole and block the surface of the guide hole 3, thus blocking the passage here. In this way, by opening multiple guide holes 3 on the connecting pressure plate 2, it is convenient for children to install different decorative ears 4 in different positions they like. For the guide hole 3 where no decorative ear 4 is installed, it can be blocked by the pop-out hole-blocking post 12 to avoid the gap being directly exposed, so that the disassembly structure on the cap 1 is aesthetically pleasing when in use.

[0031] like Figure 5 As shown, optionally, the elastic member 9 includes a fixed edge fixed to one side of the positioning protrusion 8, a bent edge is formed on the fixed edge, the bent edge forms a certain angle with the fixed edge, and the bent edge abuts against one side of the adjacent stop plate 6.

[0032] In this embodiment, the elastic element 9 is set as a spring sheet. The spring sheet's rebound direction makes the included angle between the bent edge and the fixed edge tend to increase, which makes it convenient to reset the stop plate 6 through the elastic element 9 when the pull rope 11 is not pulled, thus facilitating the reuse of the disassembly unit.

[0033] like Figure 5 As shown, optionally, a channel is formed on the positioning protrusion 8, through which the adjacent pull rope 11 passes.

[0034] In this embodiment, the channel and the axis of the pull rope 11 are located on the same horizontal plane, so that when the force applied to the pull rope 11 by the control end 10 is applied to the stop plate 6, it will not generate a component force tilted to the plane of the stop plate 6, thus avoiding bending and damage to the stop plate 6 after long-term use and improving the service life of the structure.

[0035] like Figure 4 As shown, optionally, a guide ring 15 is formed on the decorative ear 4, the outer diameter of the guide ring 15 matches the inner diameter of the guide hole 3, and the positioning notch 5 is located on the guide ring 15.

[0036] In this embodiment, the guide ring 15 is used to position the guide hole 3 to facilitate the insertion of the decorative ear 4, and the positioning notch 5 can fix the decorative ear 4 to the cap shell 1 by cooperating with the insert end 7.

[0037] Optionally, the distance between the axis of the guide hole 3 and the rotation center of the adjacent stop plate 6 is the same as the distance between the axis of the hole-blocking post 12 and the rotation center of the adjacent stop plate 6, and the outer diameter of the hole-blocking post 12 matches the inner diameter of the guide hole 3.

[0038] In this embodiment, the spacing is fixed, which makes it easier for the blocking plate 6 to rotate. At a certain moment, the hole-blocking post 12 can be coaxially aligned with the corresponding guide hole 3, so that the hole-blocking post 12 can be inserted into the corresponding guide hole 3 under the action of the spring 14, thereby improving the installation accuracy and ensuring the complete use of the function.

[0039] like Figure 5 As shown, optionally, the insert 7 includes an arc-shaped groove formed on one side of the stop plate 6, the inner diameter of the arc-shaped groove being smaller than the inner diameter of the guide hole 3.

[0040] In this embodiment, the arc-shaped groove can increase the contact area between the insert end 7 and the corresponding positioning notch 5 when the insert end 7 is engaged, which helps to improve the stability when fixing the decorative ear 4.

[0041] like Figure 1-3 As shown, optionally, the connecting pressure plate 2 is a shell structure, and a cavity is formed between it and the cap shell 1, with the disassembly unit located inside the cavity.

[0042] In this embodiment, the housing structure connecting the pressure plate 2 can be easily injection molded, and the resulting cavity provides space for the installation of the disassembly unit, which helps to protect the relevant structures in the disassembly unit and improves structural safety.

[0043] like Figure 1-3 As shown, optionally, the connecting pressure plate 2 has three ends, wherein the ends on both sides are mirror-distributed along the axis of the guide hole 3 on the middle end, and the guide hole 3 corresponds to the number of ends and is opened on the corresponding ends.

[0044] In this embodiment, three ends are provided to facilitate children to install the single horn and the two diagonal ends on both sides, giving more options for the installation method of the decorative ear 4 and increasing the target audience of the structure.

[0045] like Figure 2 and Figure 4 As shown, optionally, the decorative ear 4 has a disc body, the outer diameter of which is larger than the inner diameter of the guide hole 3.

[0046] In this embodiment, the disc is used to position the depth to which the bottom of the decorative ear 4 is inserted into the guide hole 3, so that the user can know when it is installed in place and use it conveniently.

[0047] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
