Description

Technical Field

[0001] This application relates to the field of building space safety facilities technology, and in particular to a modular combination wide-angle lens based on the concept of accessibility. Background Technology

[0002] In densely populated building environments such as schools, hospitals, rehabilitation centers, nursing homes, homes, and hotels, there are numerous blind spots, including corners, behind doors, corridor bends, and stairwell junctions. When people, especially children and teenagers prone to recklessness, the hearing impaired, the elderly with mobility difficulties, and other special groups, walk or move quickly in these areas, they are unable to anticipate people or objects coming from the other side of the blind spot, greatly increasing the risk of head-on collisions and posing a serious safety hazard. This common hazard directly reflects the shortcomings in visual accessibility design in public spaces.

[0003] To address the aforementioned issues, existing technologies disclose several wide-angle reflectors, such as circular convex wide-angle mirrors commonly used in road traffic or large warehouse environments. However, these wide-angle mirrors are typically designed for outdoor or industrial environments, and their structures are generally bulky, large in size, and relatively complex to install, requiring the use of expansion bolts for fixation. Placing them directly on the ground using poles or similar methods poses safety hazards; while fixing them directly to walls with bolts presents challenges in terms of ease of replacement and maintenance.

[0004] Furthermore, current indoor and outdoor wide-angle lenses on the market are typically one-piece structures with fixed sizes and shapes, resulting in poor adaptability and limited functionality. This manifests in two main ways: firstly, single-specification products often fail to perfectly match different corners or walls; secondly, users cannot expand or adjust the lens body according to actual site needs. This forces manufacturers to develop and produce a variety of different specifications to meet diverse market demands, increasing production and warehousing costs while also limiting user choice and installation flexibility.

[0005] Therefore, existing wide-angle lens products generally cannot simultaneously meet the comprehensive needs of modern indoor environments for safety, ease of installation, and structural adaptability. There is an urgent need for a new type of wide-angle lens solution that can be flexibly combined, conveniently installed, and adaptable to diverse scenarios. Utility Model Content

[0006] To address the aforementioned issues, this application aims to provide a modular wide-angle lens based on the concept of accessibility. Through the design of one or more standardized lens bodies and multiple connecting mechanisms on the lens bodies, it provides a wide-angle lens solution that can be standardized to produce a single lens body, flexibly combined, and adapted to diverse scenarios.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: A modular wide-angle lens based on the concept of accessibility includes one or more lens bodies and multiple connecting mechanisms; the multiple connecting mechanisms are located on the lens bodies; wherein, the lens bodies are connected to the wall through the connecting mechanisms, and the multiple lens bodies are connected to each other through the connecting mechanisms.

[0008] This design allows multiple mirror units to be assembled using a connecting mechanism to fit different walls and functions, or to be directly connected to the wall using a connecting assembly mechanism. Multiple identical mirror units and connecting mechanisms can be prefabricated, enabling multi-functional and multi-scenario applications.

[0009] Furthermore, the connection mechanism includes a plug-in assembly and a plug-in tube; the plug-in assembly is located on the outside of the lens body; the plug-in tube is disposed inside the lens body and is configured in conjunction with the plug-in assembly.

[0010] With this design, when multiple mirror bodies are spliced ​​together, the plug-in component and the plug-in cylinder are fitted together on two adjacent mirror bodies. Through the cooperation of the connecting component and the plug-in cylinder, a seamless or micro-seam connection of multiple mirror bodies can be achieved. When it is necessary to connect the mirror body to a wall, the plug-in cylinder is pre-set in the wall, and the corresponding plug-in component is set on the mirror body. In some embodiments, a plug-in cylinder and a plug-in component are respectively set on both sides of the mirror body, and the positions of the plug-in cylinder and the plug-in component on both sides are opposite, which can achieve standardized manufacturing of mirror bodies and good splicing.

[0011] Furthermore, the insertion assembly includes an outer cylinder and an inner cylinder; the outer cylinder is connected to the mirror body and is used to fit into the insertion cylinder; the inner cylinder is slidably sleeved inside the outer cylinder, and an elastic element is provided between the inner cylinder and the outer cylinder; wherein, the inner cylinder is provided with multiple spring pins, the outer cylinder is provided with a limit trigger, the limit trigger is used to release the inner cylinder; the spring pins are used to limit the insertion assembly and the insertion cylinder.

[0012] This design clarifies the implementation of the plug-in assembly. The outer cylinder mates with the plug-in tube and can be directly inserted into it. Once the outer cylinder is inserted, a limit trigger is activated, releasing the limit on the inner cylinder, which then pops out under the action of the elastic element. After the inner cylinder pops out, since there is no limit on the inner wall of the outer cylinder, multiple spring pins pop out, limiting the end of the plug-in tube. This achieves the limiting of both the plug-in assembly and the plug-in tube. The entire process simply requires inserting the plug-in assembly directly into the plug-in tube.

[0013] Furthermore, the limit trigger includes a limit rod and a trigger block; the limit rod is rotatably connected to the outer cylinder and a torsion spring is provided between the limit rod and the outer cylinder, and a limit head for limiting the inner cylinder is provided at one end of the limit rod; the trigger block is slidably disposed on the outer cylinder and is configured to cooperate with the limit rod to release the limit rod from limiting the inner cylinder.

[0014] This design clarifies the implementation of the limit trigger. The limit head at one end of the limit rod limits the rear end of the inner cylinder, overcoming the elastic force of the elastic element and keeping the inner cylinder inside the outer cylinder, thus limiting the inner cylinder. When the trigger block is pressed down by the pressure of the inner wall of the insertion cylinder, the trigger block further presses down on the other end of the limit rod, overcoming the elastic force of the torsion spring, causing the limit rod to rotate, thereby releasing the fit between the limit head and the rear end of the inner cylinder, thus releasing the limit.

[0015] Furthermore, the wide-angle lens also includes multiple reset mechanisms, which are located on the lens body and correspond one-to-one with multiple connecting mechanisms.

[0016] This design provides a reset function for the connection mechanism, allowing the connection between multiple mirrors, as well as the connection between a mirror and a wall, to be released via the reset mechanism.

[0017] Furthermore, the reset mechanism includes a reset rod and multiple connecting ropes; the reset rod is slidably disposed on the mirror body; one end of each of the multiple connecting ropes is connected to the reset rod, and the other end is connected to multiple spring pins in a corresponding manner; wherein, the connecting ropes are provided with a through-plug assembly.

[0018] This design clarifies the implementation of the reset mechanism. Pulling the reset rod retracts multiple spring pins via connecting ropes; once the spring pins retract, the limit between the insertion assembly and the insertion cylinder is released, allowing the insertion assembly to be removed. Simultaneously, the trigger block and limit rod of the limit trigger reset. Continuing to pull the reset rod pulls the inner cylinder back into the outer cylinder, and the rear end of the inner cylinder re-engages with the limit head at the end of the limit rod, thus resetting the corresponding connecting mechanism.

[0019] Preferably, both the mirror body and the connector assembly are equipped with pulleys for changing the direction of the connecting rope.

[0020] This design makes pulling the connecting rope easier and reduces wear.

[0021] In summary, this application has at least one of the following beneficial effects: 1. This application endows the wide-angle lens with modular characteristics by setting a unified connection mechanism that can be used for both wall connection and lens-to-lens connection. This not only allows individual lenses to be installed and used independently, but also allows multiple lenses to be arbitrarily combined according to actual needs, thus flexibly adapting to different corners or special layouts. This facilitates standardized production of lenses and connection mechanisms, thereby reducing manufacturing costs, improving the versatility and replaceability of components, and greatly enhancing the product's multifunctionality and market adaptability.

[0022] 2. The connecting mechanism employs a plug-in assembly and a plug-in cylinder, with a cleverly designed self-locking structure within the plug-in assembly consisting of inner and outer cylinders, an elastic element, a spring pin, and a limit trigger. During installation, simply pushing the plug-in assembly into the plug-in cylinder automatically triggers the locking mechanism, eliminating the need for additional tools or complex operations. This significantly simplifies the installation process and greatly improves installation efficiency. Furthermore, the reliable engagement between the spring pin and the plug-in cylinder ensures a stable and secure connection.

[0023] 3. By setting up a reset mechanism that corresponds one-to-one with the connecting mechanism, the problem of inconvenient disassembly of self-locking connections is solved. By operating a simple reset rod and connecting rope, the locking spring pin can be retracted, easily releasing the connection between mirrors or between a mirror and the wall. This not only makes the disassembly, replacement, or rearrangement of mirrors convenient and quick, but also enables the reusability of the connecting mechanism and allows it to be quickly restored to its initial standby state, improving the practicality and maintenance convenience of the entire system.

[0024] 4. A wide-angle mirror device with flexible structure, easy installation and adaptability to various indoor corner shapes is provided to eliminate blind spots, improve safety of movement, and especially meet the spatial perception needs of children, hearing-impaired people, the elderly and other special groups.

[0027] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "front end", "rear end", "inner side", "outer side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Reference Figures 1 to 7 This invention provides a modular wide-angle mirror based on accessibility principles, comprising one or more mirror bodies 1 and multiple connecting mechanisms; the connecting mechanisms are mounted on the mirror body 1. The mirror body 1 can be connected to a wall via the connecting mechanisms, and multiple mirror bodies 1 can also be interconnected via the connecting mechanisms. This modularity allows the wide-angle mirror to not only be used independently by fixing a single mirror body 1 to a wall via the connecting mechanisms, but also to be easily assembled and combined to adapt to different corners or specific wall shapes. Furthermore, this modular configuration, while meeting the accessibility design requirements of indoor or partially outdoor spaces, allows for the pre-standardized, mass-produced mirror bodies 1 and connecting mechanisms with uniform specifications. This not only helps reduce production costs and improve the versatility and replaceability of components, but also enables flexible functional combinations and scenario applications at the installation site according to actual needs.

[0031] Specifically, in some applications, the mirror body 1 is a 1 / 8 sphere, which can be spliced ​​into a 2 / 8 sphere or a 3 / 8 sphere to adapt to different wall locations; for example, a 1 / 8 sphere can be used for inner right-angle bends in corridors; a 2 / 8 sphere can be used for straight sections of corridors; and a 3 / 8 sphere can be used for outer right-angle bends in straight sections of corridors. These applications can effectively broaden the field of vision and improve indoor safety according to actual application scenarios. It should be noted that the above specific applications should not limit the scope of protection of this utility model, but are only application examples; applications that can be obviously conceived by those skilled in the art under the technical means and concepts of this utility model.

[0032] In one specific implementation, the connecting mechanism includes a plug-in component 2 and a plug-in tube 3. The plug-in component 2 is located on the outside of the mirror body 1, while the plug-in tube 3 is disposed inside the mirror body 1 and is positioned to cooperate with the plug-in component 2. When multiple mirror bodies 1 need to be spliced, the plug-in component 2 on one mirror body 1 can be inserted into the corresponding plug-in tube 3 of the adjacent mirror body 1. Through the plug-in cooperation of the two, a stable and almost seamless connection between multiple mirror bodies 1 can be achieved, ensuring the overall aesthetics. When it is necessary to fix the mirror body 1 to the wall, one or more plug-in tubes 3 that are compatible with the plug-in component 2 on the mirror body 1 can be pre-embedded or fixed in the wall. Then, the plug-in component 2 of the mirror body 1 can be inserted into them to complete the installation, simplifying the complexity of wall installation. In a preferred embodiment, each mirror body 1 may be symmetrically or staggeredly provided with a plug-in component 2 and a plug-in tube 3 on both sides, for example, the left side is the plug-in component 2 and the right side is the plug-in tube 3. In this way, all mirror bodies 1 can be manufactured according to a uniform standard, which aims to achieve a natural end-to-end connection when splicing, thereby improving the convenience of production and installation.

[0033] In some embodiments, to achieve reliable locking and convenient triggering, the insertion assembly 2 may specifically include an outer cylinder 21 and an inner cylinder 22. The outer cylinder 21 is fixedly connected to the lens body 1, and its outer diameter is adapted to the inner diameter of the insertion cylinder 3 for smooth insertion into the insertion cylinder 3. The inner cylinder 22 is slidably fitted into the internal cavity of the outer cylinder 21, and an elastic element 23 (e.g., a compression spring) is provided between the inner cylinder 22 and the outer cylinder 21. In its natural state, the elastic element 23 applies an elastic thrust to the inner cylinder 22, causing it to move outward from the outer cylinder 21. A plurality of radially retractable spring pins 221 are provided on the outer wall of the inner cylinder 22, while a limit trigger is provided on the outer cylinder 21. The limit trigger is used to release the inner cylinder 22 in the initial state, preventing it from accidentally popping out under the action of the elastic element 23. At the same time, the spring pins 221, in the extended state, are used to engage with the end of the insertion cylinder 3 (or, in other configurations, an internal slot engagement), thereby locking the relative position of the entire insertion assembly 2 and the insertion cylinder 3.

[0034] Thus, in the initial state, the limit trigger locks the inner cylinder 22 inside the outer cylinder 21, and the spring pin 221 is confined by the inner wall of the outer cylinder 21 and is in a retracted state. When the outer cylinder 21 is pushed into the plug-in cylinder 3, the inner wall or end face of the plug-in cylinder 3 acts on the limit trigger, triggering it and releasing the limit on the inner cylinder 22. At this time, the inner cylinder 22 quickly pops out axially under the drive of the elastic element 23. As the inner cylinder 22 moves, the spring pin 221 on it is no longer constrained by the inner wall of the outer cylinder 21, and thus automatically pops out under its own elastic force and gets stuck in the end of the plug-in cylinder 3 (or the preset limit hole / slot). This process realizes automatic and rapid locking between the plug-in assembly 2 and the plug-in cylinder 3, and the entire installation action can be completed with only one simple insertion operation.

[0035] In some embodiments, to make the limit trigger structure more reliable, it may specifically include a limit rod 211 and a trigger block 212. The limit rod 211 is rotatably connected to the outer cylinder 21 via a rotating shaft, and a torsion spring is provided between the limit rod 211 and the outer cylinder 21, which drives the limit rod 211 to always tend towards the limit position. One end of the limit rod 211 is provided with a limit head 2111 for holding or abutting the rear end of the inner cylinder 22. The trigger block 212 is slidably disposed through the wall of the outer cylinder 21 and cooperates with the other end of the limit rod 211.

[0036] Thus, in the initial locked state, the torsion spring holds the limiting rod 211 at a specific angle, and the limiting head 2111 at one end extends into the slot at the rear end of the inner cylinder 22 for engagement, thereby overcoming the elastic force of the elastic element 23 between the inner cylinder 22 and the outer cylinder 21, so that the inner cylinder 22 is reliably locked inside the outer cylinder 21. When the insertion assembly 2 is pushed into the insertion cylinder 3, the outer side of the trigger block 212 contacts the end face or inner wall of the insertion cylinder 3 and is subjected to pressure, which causes it to slide inward. The sliding of the trigger block 212 further pushes the non-limiting end of the limiting rod 211, thereby overcoming the torque of the torsion spring and causing the entire limiting rod 211 to rotate around its axis. As the limiting rod 211 rotates, the limiting head 2111 at its other end will release from the latching groove at the rear end of the inner cylinder 22, no longer obstructing the inner cylinder 22, thus instantly releasing the limiting of the inner cylinder 22 and triggering the subsequent ejection of the inner cylinder 22 and locking action of the spring pin 221.

[0037] In some embodiments, to enable the connection structure to be repeatedly disassembled and reassembled, the wide-angle lens may also include multiple reset mechanisms. These reset mechanisms are located on the lens body 1 and correspond one-to-one with each of the multiple connection mechanisms. The reset mechanisms provide unlocking and resetting functions for the connection mechanisms. Whether connecting lens bodies 1 to each other or connecting lens body 1 to a wall, the locking can be easily released by operating the corresponding reset mechanism, thereby enabling the disassembly, replacement, or rearrangement of the lens body 1.

[0038] In one specific implementation, the reset mechanism may include a reset rod 41 and multiple connecting ropes 42. The reset rod 41 is slidably mounted on the lens body 1, with a portion exposed outside the lens body 1 for easy gripping and operation by the user. One end of each of the multiple connecting ropes 42 is connected to the reset rod 41, while the other end passes through the internal channel of the insertion assembly 2 and is connected to each spring pin 221.

[0039] Thus, when unlocking is required, the user pulls or pushes the reset lever 41 in a specific direction. The movement of the reset lever 41 simultaneously pulls multiple spring pins 221 connected to it inward through multiple connecting ropes 42, causing them to overcome their own elasticity and retract into the inner cylinder 22. Once all the spring pins 221 have retracted, their limiting effect on the plug-in cylinder 3 is released, and the entire plug-in assembly 2 can then be smoothly pulled out of the plug-in cylinder 3. During the pulling process, since it is no longer under the pressure of the inner wall of the plug-in cylinder 3, the limit lever 211 of the limit trigger will automatically return to the initial limit preparation state under the action of the torsion spring, and at the same time, the other end of the limit lever 211 will push the trigger block 212 out again. After the plug-in assembly 2 is completely pulled out, the reset rod 41 can be pulled back to the outer cylinder 21 via the connecting rope 42 until the rear end of the inner cylinder 22 is locked again by the limiting head 2111 of the limiting rod 211, thus completing the reset operation of the entire connection mechanism and preparing it for the next plug-in locking.

[0040] As a preferred technical solution, to ensure smooth sliding of the connecting rope 42 within the complex internal space and reduce wear, guide pulleys are provided at locations within the mirror body 1 and the insertion assembly 2 where the direction of the connecting rope 42 needs to be altered. The pulleys transform the sliding friction of the connecting rope 42 into rolling friction, which not only significantly reduces the pulling force required to operate the reset mechanism, making the unlocking process more effortless, but also effectively reduces wear between the connecting rope 42 and internal components, thereby improving the durability and long-term reliability of the entire reset mechanism.
