Description

Technical Field

[0001] The utility model relates to the technical field of locomotive helmets, and particularly to a helmet with a detachable inner lining. Background Art

[0002] A helmet is a device that can protect the head. It is mostly semi-circular and mainly consists of a shell, an inner lining, and a suspension device. The inner lining of the helmet cannot be removed from the shell during factory production. Although there are a few types of helmets with removable inner linings, professional disassembly skills and tools are required, and ordinary people cannot operate them.

[0003] With the accelerating pace of economic development, people have a deeper understanding of health. Safe travel is the top priority. Therefore, wearing a helmet is an essential tool. The inner lining of the helmet, which comes into long-term contact with the human body, is particularly important. Due to long-term wearing, sweat and dirt will remain on the surface of the inner lining, making it impossible to clean, increasing the discomfort of the wearer. If a new helmet is purchased, it will increase the cost and is not environmentally friendly. For the very few helmets with removable inner linings, they are expensive and have high disassembly requirements, making them impossible to popularize. Summary of the Utility Model

[0004] Aiming at the technical problems existing in the prior art, the utility model provides a helmet with a detachable inner lining. Through the combination of magnetic principles and structural design, it is convenient to remove the inner lining of the helmet for cleaning. The disassembly and assembly technical requirements are low, and it is suitable for popularization.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A helmet with a detachable inner lining includes a shell body, an inner lining, and a positioning member for detachably connecting the shell body and the inner lining;

[0006] The positioning member includes a lower layer plate connected to the shell body and an upper layer plate connected to the inner lining. The shell body and the inner lining are connected by the magnetic force between the upper layer plate and the lower layer plate.

[0007] As a further technical solution, a plurality of first grooves are provided at intervals on the surface of the lower layer plate facing the upper layer plate, and first magnets are fixed in the first grooves.

[0008] As a further technical solution, a plurality of protruding portions are provided at intervals on the surface of the lower layer plate facing away from the upper layer plate. The protruding portions are cavity structures with openings facing the upper layer plate. The first grooves extend to and communicate with the protruding portions, so that after the first magnets are fixed in the cavities of the protruding portions, their tops are exposed at the bottom end surfaces of the first grooves;

[0009] The opening area of the protruding portion is smaller than the area of the surface of the first magnet facing the first groove.

[0010] As a further technical solution, a protruding second magnet is provided on the side of the upper layer plate facing the lower layer plate. The second magnet is adapted to be inserted into the first groove and attracted to the first magnet to fix the shell body and the inner lining.

[0011] As a further technical solution, the area of the side of the second magnet facing the lower layer plate is equal to the opening area of the protruding part.

[0012] As a further technical solution, the outer shapes of the first groove and the second magnet are both frustum-cylindrical. When the second magnet is placed in the first groove, there is a gap between the circumferential surface of the second magnet and the side wall of the first groove.

[0013] As a further technical solution, the lower layer plate is adapted to be disposed along the front edge of the buffer layer in the shell body; the upper layer plate is adapted along the front edge of the inner lining so that the upper layer plate and the lower layer plate are correspondingly connected.

In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present utility model can be implemented without the use of these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present utility model with unnecessary details. Therefore, the present utility model is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0032] This embodiment provides a helmet with a detachable inner lining to solve the technical problem that the inner lining 2 of the helmet is not detachable or has high technical requirements for disassembly, and the inner lining 2 cannot be cleaned, so as to improve the comfort and experience when wearing the helmet. Refer to Figures 1 - 3 , which specifically includes a shell body 1, an inner lining 2, and a positioning member 3 for detachably connecting the shell body 1 and the inner lining 2; the positioning member 3 includes a lower layer plate 31 connected to the shell body 1 and an upper layer plate 32 connected to the inner lining 2, and the shell body 1 and the inner lining 2 are connected by the magnetic force between the upper layer plate 32 and the lower layer plate 31.

[0033] In this embodiment, when it is necessary to remove the inner lining 2 from the helmet for cleaning or replacement, just pull the upper layer plate 32 off the lower layer plate 31 by hand, and the inner lining 2 can be removed from the shell body 1. When the removed inner lining 2 is cleaned and dried, the upper layer plate 32 and the lower layer plate 31 can be made to attract each other by magnetic force.

[0034] In the specific implementation process, refer to Figure 5 、 Figure 6 , a plurality of first grooves 311 are provided at intervals on the surface of the lower layer plate 31 facing the upper layer plate 32, and first magnets 312 are fixed in the first grooves 311, so that the first magnets 312 attract the upper layer plate 32 to connect and fix the inner lining 2 and the shell body 1.

[0035] Furthermore, refer to Figure 3 、 Figure 6, on the side of the lower layer board 31 facing away from the upper layer board 32, there are a number of protruding parts 313 arranged at intervals. The protruding part 313 is a cavity structure with an opening on the side facing the upper layer board 32. The first groove 311 extends to the protruding part 313 and communicates with it, so that after the first magnet 312 is fixed in the cavity of the protruding part 313, its top end is exposed on the bottom end surface of the first groove 311; the opening area of the protruding part 313 is smaller than the area of the surface of the first magnet 312 facing the first groove 311, to prevent the first magnet 312 from detaching from the lower layer board 31; one first groove 311 corresponds to one protruding part 313 and one first magnet 312.

[0036] For example, the protruding part 313 is a six-sided box structure, and there is an opening on the side facing the upper layer board 32, and the first magnet 312 is accommodated in this six-sided box structure, and the part exposed from the opening is magnetically attracted to the upper layer board 32. Another example is that there is also an opening on the side of the six-sided box structure facing away from the opening, but the opening area of this side is smaller than the area of the corresponding surface of the first magnet 312, as long as the first magnet 312 does not fall out from the side opening, which can reduce the overall weight of the helmet to a certain extent.

[0037] Correspondingly, referring to Figure 4 , on the side of the upper layer board 32 facing the lower layer board 31, there is a protruding second magnet 321. The second magnet 321 is inserted into the first groove 311 in a matching manner and attracted to the first magnet 312 to fix the shell body 1 and the inner lining 2. That is, the connection between the upper layer board 32 and the lower layer board 31 is formed by the attraction between the first magnet 312 and the second magnet 321, and one first magnet 312 corresponds to one second magnet 321. To make the connection between the inner lining 2 and the shell body 1 more stable, the area of the side of the second magnet 321 facing the lower layer board 31 is equal to the opening area of the protruding part 313.

[0038] For example, the outer shapes of the first groove 311 and the second magnet 321 are both frustum-shaped columns, and when the second magnet 321 is placed in the first groove 311, there is a gap between the circumferential surface of the second magnet 321 and the side wall of the first groove 311, which is convenient for the disassembly of the inner lining 2 and the shell body 1.

[0039] In the specific implementation process, referring to Figure 1 、 Figure 2 , the lower layer board 31 is adaptively arranged along the front edge of the buffer layer 11 inside the shell body 1; the upper layer board 32 is adapted along the front edge of the inner lining 2 so that the upper layer board 32 and the lower layer board 31 are correspondingly connected.

[0040] For example, the upper layer plate 32 and the lower layer plate 31 are both arranged at the position corresponding to the forehead on the helmet. For the convenience of disassembly, the lower layer plate 31 is adaptively arranged along the thickness direction of the edge of the buffer layer 11, and the width of the lower layer plate 31 is less than or equal to the thickness of the buffer layer 11, so that the cross-section of the lower layer plate 31 is arc-shaped to be adapted to the buffer layer 11, that is, the protruding part 313 extends into the position where the buffer layer 11 has a depression. At this time, the opening of the first groove 311 is arranged downward. Correspondingly, the upper layer plate 32 has a structure that is stacked and adapted to the lower layer plate 31, that is, the cross-sectional arcs of the two are the same, and the inner edge 21 of the upper layer plate 32 and the outer edge of the inner lining 2 can be fixedly connected, such as by sewing.

[0041] For the convenience of disassembly, a first depression section 314 is arranged between adjacent first grooves 311 on the lower layer plate 31. Correspondingly, a second depression section 322 is arranged between adjacent second magnets 321 on the upper layer plate 32. The first depression section 314 is recessed in a direction away from the upper layer plate 32, and the second depression section 322 is recessed in a direction away from the lower layer plate 31. The first depression section 314 and the second depression section 322 are opposite to each other so that there is a gap between them, which is convenient for the operator to hold the upper layer plate 32 by hand from the gap and peel it off the lower layer plate 31.

[0042] Furthermore, to avoid slipping of the hand during peeling, see Figure 3 、 Figure 4 , at least one support piece 323 is arranged on the surface of the second depression section 322 facing the first depression section 314, and the support piece 323 abuts against the end face of the first depression section 314.

[0043] Correspondingly, see Figure 3 , the part of the lower layer plate 31 where the first depression section 314 is not arranged overlaps with the part of the upper layer plate 32 where the second depression section 322 is not arranged.

[0044] In the specific operation process, see Figure 2 、 Figure 7, to enhance the connection stability between the inner lining 2 and the buffer layer 11, the positioning member 3 further includes a connecting piece 33 provided on the other side of the inner lining 2. The connecting piece 33 is provided on the side of the inner lining 2 facing the buffer layer 11, and a plurality of third magnets 331 are arranged at intervals on the connecting piece 33; a plurality of second grooves 111 with built-in fourth magnets 112 are provided on the buffer layer 11, so that after the third magnets 331 are inserted into the second grooves 111, they attract the fourth magnets 112 to fix the buffer layer 11 and the inner lining 2; the upper plate 32 and the connecting piece 33 are respectively located at the upper and lower parts of the inner lining 2; that is, the upper plate 32 is provided on the arc section of the helmet close to the forehead, and the connecting piece 33 is located at the position of the helmet covering the neck.

[0045] For example, the depth of the second groove 111 is greater than the thickness of the fourth magnet 112, and preferably the part of the second groove 111 for inserting the third magnet 331 is adapted to the shape of the third magnet 331. Preferably, the shape of the third magnet 331 is a conical column, and the end with a small circular area on the conical column is inserted into the second groove 111 to attract the fourth magnet 112; for example, a card slot for engaging the fourth magnet 112 is provided on the side of the second groove 111 facing away from the third magnet 331. After the fourth magnet 112 is engaged in the card slot, the third magnet 331 is inserted into the second groove 111 to magnetically attract the fourth magnet 112.

[0046] In the specific implementation process, the upper plate 32, the lower plate 31, and the connecting piece 33 are all made of polypropylene material.

[0047] This embodiment is implemented as follows:

[0048] When the inner lining 2 needs to be removed from the helmet, hold the upper plate 32 and pull it off to separate the first magnet 312 and the second magnet 321, and then hold the other end of the inner lining 2 to separate the third magnet 331 and the fourth magnet 112, and the inner lining 2 can be removed from the helmet for subsequent processing, such as cleaning;

[0049] When the inner lining 2 needs to be installed on the helmet, put the inner lining 2 into the helmet, and then align the second magnet 321 with the first magnet and the third magnet 331 with the fourth magnet to complete the installation of the inner lining 2.

[0050] This embodiment has a simple structure, is convenient for disassembly and assembly, has low technical requirements for operators, and the inner lining 2 can be removed from the helmet at any time for cleaning or replacement.

[0051] It should be noted that in the above embodiments, the descriptions of the respective embodiments have their own emphases. For the parts not described in detail in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0052] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
