Description

Technical Field

[0001] This utility model relates to the field of positioning tags, and more particularly to a shell for a positioning tag for a safety helmet and a positioning tag containing the same. Background Technology

[0002] A safety helmet is a hat designed to protect the head from injuries caused by falling objects and other specific factors. A safety helmet consists of a shell, liner, chin strap, and accessories.

[0003] The helmet shell is the main component of a safety helmet, generally employing an elliptical or hemispherical thin-shell structure that undergoes pressure deformation under impact. Due to the rigidity of the material, it absorbs and disperses stress, and its smooth surface and circular curves allow impacting objects to slide away, reducing impact time. Depending on the needs and to enhance the strength of the helmet shell, it can be manufactured in various forms, such as smooth top, top rib, with a brim, or without a brim.

[0004] With increased awareness of safe construction practices, wearing safety helmets during work is of paramount importance. Therefore, for management purposes, safety helmets are now often fitted with positioning tags that provide location tracking.

[0005] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0006] Currently, positioning tags are often fixed to safety helmets by pasting or binding. However, the outer shell of the positioning tag is flat, while the shape of the safety helmet is curved. The positioning tag can easily fall off due to vibration, collision, or other reasons, thus affecting its normal operation.

[0007] Therefore, there is a need for a housing for a positioning tag for a safety helmet and a positioning tag containing therein, in order to at least partially solve the above-mentioned technical problems. Utility Model Content

[0008] This utility model provides a shell for a positioning tag on a safety helmet and a positioning tag containing the shell, which can solve the problem of positioning tags easily falling off.

[0009] In a first aspect, this utility model provides a housing for a positioning tag on a safety helmet, the housing comprising:

[0010] The shell body has a contact portion on its bottom surface in the vertical direction for fitting to the shell of the safety helmet;

[0011] The contact portion includes a concave surface that is adapted to the outer curved surface of the helmet shell. The concave surface is constructed as a smooth curved surface structure that is low in the middle and high at both ends along a first horizontal direction and low at one end and high at the other end along a second horizontal direction.

[0012] According to the outer shell of this utility model, a contact part for attaching to the shell of the safety helmet is specially provided on the bottom surface of the shell body in the vertical direction. The concave surface of the contact part is adapted to the outer curved surface of the safety helmet shell, so that the surface can be tightly attached to the shell of the safety helmet. Thus, after the positioning label is attached to the shell of the safety helmet, it can be made not to fall off.

[0013] Optionally, the contact portion is configured as a protrusion protruding outward relative to the bottom surface of the shell body, and the concave surface is recessed into the bottom surface of the protrusion in the vertical direction.

[0014] According to this solution, by setting a concave surface through a protrusion protruding from the shell body, it will not affect the shell body itself and is easy to manufacture.

[0015] Optionally, the shell body also has connecting portions on both sides along the first direction, the connecting portions being detachably connected to a safety helmet or human wrist via a connector.

[0016] According to this solution, the connecting part enables detachable connection to the safety helmet or human wrist, facilitating assembly and disassembly.

[0017] Optionally, the connecting portion is configured as a connecting lug protruding outward relative to the shell body, the connecting lug having a through hole through which the connecting member passes.

[0018] According to this solution, the connecting part adopts a connecting ear type with through holes, which has a simple structure and good performance.

[0019] Optionally, a push-button switch is also provided on the top surface of the shell body. The positioning tag has a control unit and an alarm unit. The control unit is electrically connected to the push-button switch and the alarm unit respectively. The control unit is used to control the alarm unit to issue a warning when the push-button switch is pressed down to conduct.

[0020] According to this solution, the alarm function is achieved by locating the tag through push-button switches, alarm units, etc.

[0021] Secondly, this utility model also provides a positioning tag for safety helmets, including the outer shell of the above-mentioned technical solution.

[0022] According to the positioning tag of this utility model, since it has an outer shell that can be tightly attached to the shell of the safety helmet, it is not easy to fall off after being attached to the shell of the safety helmet.

[0023] The beneficial effects that can be obtained by utilizing the technical solution according to the embodiments of this utility model are at least as follows:

[0024] 1. The outer shell of this utility model has a contact part for attaching to the shell of the safety helmet, which is additionally provided on the bottom surface of the shell body. The concave surface of the contact part achieves a tight surface-to-surface fit on the shell of the safety helmet, making it difficult for the positioning tag to fall off after it is attached to the shell of the safety helmet.

[0025] 2. The outer shell of this utility model can be quickly and detachably connected to the safety helmet through the connecting ear with through hole, and the fixing method between it and the safety helmet is simple and quick;

[0026] 3. The outer shell of this utility model has a simple structure and is easy to manufacture.

[0049] The objectives and functions of this invention, as well as the methods for achieving these objectives and functions, will be clarified by referring to exemplary embodiments. However, this invention is not limited to the exemplary embodiments disclosed below; it can be implemented in various forms. The purpose of this specification is merely to help those skilled in the art to comprehensively understand the specific details of this invention.

[0050] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0051] The ordinal numbers such as "first" and "second" used in this invention are merely identifiers and have no other meaning, such as a specific order. Furthermore, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0052] It should be noted that the terms “up,” “down,” “front,” “back,” “left,” “right,” “inner,” “outer,” and similar expressions used in this article are for illustrative purposes only and are not intended to be limiting.

[0053] This invention provides a housing 100 for a positioning tag on a safety helmet. The housing 100 can be applied, for example, to positioning tags such as UWB tags, and can solve the problem that existing positioning tags easily detach from safety helmets.

[0054] It should be noted that, for ease of description, this embodiment uses a positioning tag on a safety helmet (not shown) for illustration. This is only one specific embodiment and does not imply limitation. It can also be other targets with curved surface fitting structures, as well as the wrist of a person, which will not be listed here.

[0055] The positioning tag in this application embodiment can be, for example, a UWB tag. UWB (Ultra Wide Band) technology is a carrier-free communication technology that uses nanosecond-level non-sinusoidal narrow pulses to transmit data, thus occupying a very wide frequency spectrum. Traditional positioning techniques determine object location based on signal strength, which is greatly affected by external factors, resulting in a large error between the located object's position and the actual position, leading to low positioning accuracy. UWB positioning, however, uses broadband pulse communication technology, possessing strong anti-interference capabilities, reducing positioning errors. The emergence of UWB positioning technology fills a gap in the field of high-precision positioning, offering advantages such as insensitivity to channel fading, low transmitted signal power spectral density, low interception capability, low system complexity, and centimeter-level positioning accuracy. Commonly used UWB positioning methods include three main types: Time Difference of Arrival (TDOA), Time of Flight (TOF), and Angle of Arrival (AOA). The first two can generally be used independently, while AOA is usually fused with TOF or TDOA for positioning. Generally speaking, a UWB positioning system includes a positioning base station and a positioning terminal (such as a positioning tag) set on the target being located. Therefore, UWB tags are more suitable for scenarios where wearing a safety helmet is required.

[0056] Of course, it is understandable that the location tag can also be other types of location tags, such as GPRS chips, Beidou positioning chips, etc.

[0057] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, where Figure 1 This is a schematic diagram of the outer shell of a positioning tag for a safety helmet according to an embodiment of the present invention; Figure 2 for Figure 1 The diagram shows a bottom view of the outer casing;

[0058] Figure 3 for Figure 1 A side view of the outer casing shown; Figure 4 for Figure 1 This is a schematic diagram of another side of the housing. The housing 100 may include a housing body 110 and a contact portion.

[0059] The shell body 110 serves as the housing for the positioning tag itself and is used to install devices related to the positioning tag. The contact portion, as an important component of this application, is used to achieve a surface-to-surface fit with the helmet shell.

[0060] Specifically, the shell body 110, as the shell structure of the positioning tag itself, can be a cuboid shell, a cylindrical shell, or a frustum-shaped shell, etc., as needed, and its shape is not limited.

[0061] refer to Figure 2 , Figure 3 and Figure 4 The shell body 110 has a contact portion on its bottom surface along the vertical direction L3 for fitting to the helmet shell. The contact portion may include a concave surface 121 adapted to the outer curved surface of the helmet shell. The concave surface 121 is a smooth curved surface structure with a lower middle and higher ends along the first horizontal direction L1 and a lower end and higher end along the second horizontal direction L2, so as to achieve a close surface-to-surface fit between the concave surface 121 and the outer curved surface of the helmet shell, and improve the stability during fitting.

[0062] The specific position of the concave surface 121 relative to the shell body 110 is not limited.

[0063] For example, the concave surface 121 can be part of the bottom surface of the shell body 110 and recessed therein. That is, the contact part and the concave surface 121 are of the same structure. This design makes the entire positioning tag structure relatively simpler and smaller, but the concave surface 121 will wear down after long-term use, which will also shorten the service life of the positioning tag shell body 110.

[0064] For example, refer to Figure 5 and Figure 6 Preferably, the contact portion can be a protrusion 120 that protrudes outward relative to the bottom surface of the shell body 110. In this case, the concave surface 121 is recessed into the bottom surface of the protrusion 120 along the vertical direction L3.

[0065] In this way, by providing a concave surface 121 through the protrusion 120 protruding from the shell body 110, even if the concave surface 121 is worn, it will not affect the shell body 110 itself, and this solution is also convenient for manufacturing the concave surface 121.

[0066] Furthermore, the protrusion 120 and the shell body 110 can be an integral structure or a separate structure.

[0067] According to the outer shell 100 of this utility model, a contact part for attaching to the shell of the safety helmet is specially designed on the bottom surface of the shell body 110 along the vertical direction L3. The concave surface 121 of the contact part is adapted to the outer curved surface of the helmet shell, so that the surface can be tightly attached to the helmet shell. Thus, after the positioning tag is attached to the helmet shell, it can be prevented from falling off.

[0068] To achieve a secure connection between the positioning tag and the safety helmet, the shell body 110 may also have connecting portions on both sides along the first direction L1. The connecting portions are used for detachable connection to the safety helmet via connectors.

[0069] According to this design, the shell body 110 is detachably connected to the safety helmet via a connecting part, facilitating assembly and disassembly. The specific type of the connecting part is not strictly limited. For example, the connecting part can be a hook, connecting ring, or buckle. Correspondingly, the connecting component can be a matching binding rope, strap, or a connecting rope or strap with a buckle.

[0070] refer to Figure 1 and Figure 2 In a preferred embodiment, the connecting portion may be a connecting lug 130 that protrudes outward relative to the housing body 110. The connecting lug 130 has a through hole 131 through which a connector passes.

[0071] According to this solution, the connecting part adopts a connecting ear 130 with a through hole 131. One or both ends of the detachable connector are connected to the through hole 131, and then it is sleeved or connected to the target being positioned. The connection method is simple and quick.

[0072] Regarding the through hole 131 on the connecting ear 130, it can be a long strip through hole 131 or multiple spaced through holes 131.

[0073] Preferably, the two connecting ears 130 can be symmetrically arranged on both sides of the shell body 110. The specific positions of the connecting ears 130 on both sides of the shell body 110 are not strictly limited. For example, the two connecting ears 130 can be located on the side walls of the shell body 110, or at a suitable position on the top surface of the shell body 110, or at a suitable position on the bottom surface of the shell body 110 where they do not interfere with the contact portion or concave surface 121.

[0074] In the illustrated embodiment, the connecting lug 130 can be horizontally positioned on both side walls of the housing body 110, flush with the bottom surface of the housing body 110. This makes the connection point between the connector and the connecting lug 130 lower than the housing body 110, resulting in stronger connection stability.

[0075] It is understandable that the connection between the ear 130 and the shell body 110 can be an integral structure or a separate structure.

[0076] In addition, to ensure a more secure fit between the positioning label and the outer curved surface of the helmet shell, the concave surface 121 may also be provided with anti-slip texture (not shown) or anti-slip pad to improve friction during the fit.

[0077] For example, refer to Figure 5 When the connector is a wrist strap 200, both ends of the wrist strap 200 are detachably (e.g., fastened) to the through hole 131, allowing the shell body 110 to easily switch from helmet wearing mode to wrist strap 200 wearing mode. The wrist strap 200 is made of a soft, breathable material to ensure comfort even during extended wear. The length of the wrist strap 200 is adjustable to fit different wrists. The wrist strap 200 uses an existing wrist strap 200 structure, which will not be detailed here.

[0078] refer to Figure 6 When the connector is a name tag clip 300, the user can detachably (e.g., snap it on) one end of the name tag clip 300 to the through hole 131, and clip the other end to the edge of a pocket or to clothing on the chest. Other small items, such as work ID cards or access cards, can also be hung on the name tag clip 300, improving usability. The name tag clip 300 can also adopt an existing name tag clip 300 structure.

[0079] Optionally, a push-button switch 140 may also be provided on the top surface of the housing 110. The positioning tag has a control unit and an alarm unit. The control unit is electrically connected to the push-button switch 140 and the alarm unit respectively, and the control unit is used to control the alarm unit to issue an alarm when the push-button switch 140 is pressed down to conduct.

[0080] According to this solution, the alarm function is achieved by locating the tag through a push-button switch 140, an alarm unit, etc. The push-button switch 140, the control unit, and the alarm unit are all existing technology devices; their interconnections and functional implementations are based on existing technology and do not involve any improvements to the computer program.

[0081] In summary, according to the outer shell 100 of this utility model, by providing an additional contact portion on the bottom surface of the shell body 110 for attaching to the helmet shell, the concave surface 121 of the contact portion achieves a tight surface-to-surface fit with the helmet shell, making it difficult for the positioning tag to fall off after being attached to the helmet shell; in addition, the connecting ear 130 with a through hole 131 enables quick and detachable connection to the helmet, and the fixing method between the helmet and the helmet is simple and quick; overall, the outer shell 100 of this utility model has a simple structure, good performance, and is easy to manufacture.

[0082] Secondly, this utility model also provides a positioning tag, including the outer shell 100 of the above embodiment.

[0083] Since the positioning tag according to the present utility model embodiment includes the outer shell 100 of the above embodiment, it includes all the features and effects of the outer shell 100, which will not be repeated here.

[0084] Other embodiments of the present invention will be readily conceived and understood by those skilled in the art in conjunction with the description and practice disclosed herein. The description and embodiments are to be considered exemplary only, and the true scope and spirit of the invention are defined by the claims.
