Description

Technical Field

[0001] This utility model relates to the technical field of folding devices, and more particularly to a folding device and a folding vehicle. Background Technology

[0002] Folding bikes, as a portable mode of transportation, are widely used in daily commutes and short-distance trips due to their compact structure and ease of carrying. Existing folding bikes typically need to ensure driving safety and structural stability when unfolded, while also being easy to transport and store when folded. Therefore, achieving reliable locking and smooth switching of the bike's structure under different working conditions is a key technical challenge in folding bike design.

[0003] Existing folding bike locking mechanisms generally suffer from poor structural compatibility, insecure locking, complex operation, and insufficient security, making it difficult to simultaneously meet the comprehensive requirements of structural strength, ease of operation, and security for folding bikes in both folded and unfolded states. Therefore, there is an urgent need for a folding bike locking device with a reasonable structure, reliable locking, simple operation, and the ability to independently control the folding and unfolding states, in order to improve the overall performance and user experience of folding bikes. Utility Model Content

[0004] One objective of this invention is to provide a folding device and a folding vehicle to solve the safety problem of folding vehicles.

[0005] To achieve the above objectives, the present invention provides a solution as follows: the folding device includes a base, a movable component, a first locking component, and a second locking component; the movable component is rotatably connected to the base; the first locking component is connected to the movable component, and when the folding device is in the unfolded state, the first locking component locks and fixes the base and the movable component; the second locking component is connected to the movable component, and when the folding device is in the folded state, the second locking component locks and fixes the base and the movable component.

[0006] To achieve the above objectives, another solution provided by this utility model is: a folding vehicle includes: a front wheel assembly, a rear wheel assembly, and a folding device, wherein the front wheel assembly is connected to a movable component, and the rear wheel assembly is connected to a base.

[0007] The beneficial effects of this utility model are as follows: Through the above-described structural design, the folding vehicle of this embodiment can bring significant technical benefits in actual use. First, since the first locking component is specifically designed to lock the unfolded state, it can effectively prevent accidental folding caused by insecure locking during operation, significantly improving the safety and structural stability of the product. Second, the second locking component is specifically designed to lock the folded state, ensuring that the vehicle body structure is compact after folding, facilitating transportation and storage, while preventing accidental unfolding due to loosening, thus improving ease of use. Third, the first and second locking components work independently, avoiding problems such as poor compatibility and complex operation of a single locking mechanism, achieving independent and reliable control of folding and unfolding, and reducing the risk of misoperation. Compared with the single locking mechanism commonly found in the prior art, this embodiment effectively solves the technical problem that folding vehicles cannot simultaneously balance structural strength and operational convenience in different states through a dual-locking structure. Finally, the folding and unfolding operations are smoother and clearer, improving the user experience, while the secure locking of the vehicle also extends the product's service life. In summary, this embodiment achieves reliable locking of the folding bike in both folded and unfolded states by setting two independent locking components in the folding bike, which improves safety, ease of operation and overall product stability, and effectively solves the problems of poor locking compatibility and complicated operation of existing folding bikes.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Generally, folding bikes use a single locking mechanism, typically employing a hook or latch to lock in both folded and unfolded states. While relatively simple in structure, this design has several shortcomings. First, a single locking mechanism often struggles to simultaneously meet the requirements of structural strength and ease of operation when accommodating both folding and unfolding functions. For example, a loose lock during the unfolded riding process could lead to accidental folding, posing a significant safety hazard. Second, in the folded storage state, a single locking mechanism is prone to loosening or wear, causing the bike to unfold unexpectedly, affecting both transport convenience and increased risk. Furthermore, complex linkage structures or auxiliary locking components are used to improve locking effectiveness, increasing manufacturing costs and maintenance difficulty, and potentially leading to cumbersome operation and a higher probability of misoperation, impacting user experience. Some technologies use springs or friction to assist locking, but these solutions are prone to performance degradation after long-term use, failing to consistently guarantee the security and reliability of the lock.

[0024] Please see Figures 1 to 6 As shown, Figure 1 This is a structural schematic diagram of the folding vehicle provided in the embodiment of this utility model in its unfolded state. Figure 2 This is a cross-sectional schematic diagram of the folding vehicle provided in the embodiment of this utility model in its unfolded state. Figure 3 This is provided by the embodiment of the present utility model. Figure 2 Enlarged diagram of region A in the middle.

[0025] This embodiment provides a folding bicycle, the structure of which includes a front wheel assembly 200, a rear wheel assembly 300, and a folding device 100. The front wheel assembly 200 is connected to the folding device 100 via a movable member 20, and the rear wheel assembly 300 is fixedly connected to a base 10. The folding device 100 specifically includes a base 10, a movable member 20, a first locking component 30, and a second locking component 40, wherein the movable member 20 is rotatably connected to the base 10, realizing the conversion between the unfolded state and the folded state of the folding bicycle. In the unfolded state, the first locking component 30 is connected to the movable member 20, which can firmly lock the base 10 and the movable member 20, ensuring the stability of the overall structure and safety during use; in the folded state, the second locking component 40 is connected to the movable member 20, at which time the second locking component 40 locks the base 10 and the movable member 20, thereby preventing the structure from loosening or accidentally unfolding after folding. It should be emphasized that the first locking component 30 and the second locking component 40 are set independently and do not interfere with each other. Each locking component only functions in its corresponding state, thus achieving independent and reliable control over the folding and unfolding states of the folding vehicle.

[0026] Through the above structural design, the folding vehicle of this embodiment delivers significant technical benefits in practical use. First, since the first locking component 30 is specifically designed to lock the unfolded state, it effectively prevents accidental folding due to loose locking during operation, significantly improving product safety and structural stability. Second, the second locking component 40 is specifically designed to lock the folded state, ensuring a compact vehicle structure after folding, facilitating transport and storage, while also preventing accidental unfolding due to loosening, thus enhancing ease of use. Third, the first locking component 30 and the second locking component 40 operate independently, avoiding the problems of poor compatibility and complex operation associated with single locking mechanisms, achieving independent and reliable control of folding and unfolding, and reducing the risk of misoperation. Compared to the single locking mechanism commonly found in existing technologies, this embodiment, through its dual-locking structure, effectively solves the technical challenge of folding vehicles simultaneously achieving both structural strength and operational convenience in different states. Finally, the folding and unfolding operations are smoother and more intuitive, improving the user experience, while the secure locking also extends the product's lifespan. In summary, this embodiment achieves reliable locking of the folding bike in both folded and unfolded states by setting two independent locking components in the folding bike, which improves safety, ease of operation and overall product stability, and effectively solves the problems of poor locking compatibility and complicated operation of existing folding bikes.

[0027] This embodiment provides an improved first locking component 30 for the locking structure of a folding bicycle. The first locking component 30 includes a first reset member 31 and a first locking member 32, wherein one end of the first reset member 31 is connected to the first locking member 32, and the other end is connected to the movable member 20. When the folding bicycle is in the unfolded state, the first reset member 31, through its own elasticity, pushes the first locking member 32 to maintain connection with the base 10, thereby achieving reliable locking of the base 10 and the movable member 20. Specifically, the first reset member 31 can be made of a spring or other elastic material, and its structural design ensures that it can continuously apply elastic force to the first locking member 32 in the unfolded state, keeping it in the locked position. Thus, even under external vibration or impact, the first locking member 32 is less likely to automatically detach from the base 10, effectively improving the stability of the folding bicycle structure in the unfolded state.

[0028] Through the above structural design, this embodiment achieves the following technical effects: First, the first reset member 31 enables the first locking member 32 to automatically maintain its connection with the base 10 without external force, avoiding structural instability or safety hazards caused by loose locking members or inconvenient operation in traditional technologies. Second, utilizing the elastic properties of the first reset member 31, pressure can be continuously applied to the first locking member 32, making the first locking member 32 more firmly embedded in the base 10, further improving the reliability of locking. Third, this solution can effectively solve the problem of accidental folding caused by loose locking structure or untimely reset in existing folding vehicles during operation, ensuring the safety and stability of the folding vehicle in the unfolded state. In summary, this embodiment, through the cooperative design of the first reset member 31 and the first locking member 32, achieves automatic reset and continuous locking of the locking structure, improves the structural safety and reliability of the folding vehicle in the unfolded state, and solves the problem of poor stability in the unfolded state in existing technologies.

[0029] This embodiment proposes a movable component 20 structure for the locking structure of a folding bicycle, which facilitates installation and ensures reliable locking. As shown in the figure, the movable component 20 has an assembly cavity 21 inside, which is a space for accommodating the first locking component 32. An assembly opening 22 is provided at one end of the movable component 20 along its length, communicating with the assembly cavity 21, for conveniently assembling the first locking component 32 into the assembly cavity 21. Furthermore, a locking opening 23 is provided on the peripheral sidewall of the movable component 20, also communicating with the assembly cavity 21. During the assembly of the folding bicycle, the first locking component 32 can be directly inserted into the assembly cavity 21 through the assembly opening 22 to complete the assembly of the component; when the folding bicycle is unfolded, the first locking component 32 can cooperate with the base 10 through the locking opening 23 to effectively lock the movable component 20 to the base 10. The location and size of the locking opening 23 are rationally designed to ensure that the first locking component 32 can be stably connected to the base 10 when locked, thereby improving the stability and safety of the overall structure.

[0030] Through the above structural design, this embodiment effectively solves the technical problems of complex assembly and insufficient locking reliability of the locking components in existing folding bicycles. Firstly, by providing an assembly port 22 at one end of the movable part 20, the assembly process of the first locking part 32 is simplified, allowing it to be easily and quickly embedded into the assembly cavity 21, reducing production difficulty and improving assembly efficiency. Secondly, the locking port 23 design on the peripheral sidewall ensures that the first locking part 32 can accurately and firmly engage with the base 10 when the vehicle is unfolded, preventing the first locking part 32 from loosening under vibration or impact, thus enhancing the safety and stability of the folding bicycle during use. Furthermore, the reasonable distribution of the assembly port 22 and the locking port 23 effectively avoids mutual interference between the assembly and locking processes, making the structure more reasonable and the operation simpler. In summary, this embodiment, by optimizing the structural design of the movable part 20, achieves convenient assembly and efficient locking of the first locking component 30, improving production efficiency while ensuring the safety and reliability of the folding bicycle in the unfolded state, achieving the desired technical effect.

[0031] This embodiment addresses the assembly and locking problem of the folding device 100 by proposing a sliding engagement locking structure. As shown in the figure, one of the first locking member 32 and the movable member 20 is provided with a sliding part. For example, the outer side of the first locking member 32 is provided with a protruding sliding part, and the movable member 20 is provided with a corresponding sliding groove in the axial direction of its assembly opening 22. The sliding groove extends along the axial direction of the assembly opening 22, and its internal dimensions are adapted to the sliding part. During assembly, the sliding part can be inserted from the assembly opening 22 and slide into the assembly cavity 21 along the sliding groove direction, realizing the sliding engagement between the first locking member 32 and the movable member 20. In this way, the first locking member 32 can be easily moved along the sliding groove direction, which is convenient for both assembly and subsequent locking operations. When the first locking member 32 slides to a predetermined position, it can be securely locked to the base 10 by the first reset member 31.

[0032] Through the above structural design, this embodiment effectively solves the technical problems in the prior art, such as the difficulty in assembling the first locking member 32, inaccurate positioning, and loose fit between the first locking member 32 and the movable member 20. Specifically, the sliding fit between the sliding part and the sliding groove enables the first locking member 32 to move smoothly and accurately along a predetermined trajectory, avoiding misalignment or damage of components during assembly and improving assembly efficiency and accuracy. On the other hand, the sliding fit structure enhances the tightness of the connection between the first locking member 32 and the movable member 20, preventing the first locking member 32 from loosening or shifting due to vibration or other external forces during use, thereby significantly improving the reliability and safety of the locking structure. At the same time, this technical solution also simplifies the structure, facilitates mass production, and helps reduce manufacturing costs. Therefore, this embodiment achieves efficient assembly and reliable locking of the first locking member 32 and the movable member 20 through the sliding fit between the sliding part and the sliding groove, improving assembly convenience and usage stability, and achieving the technical effects of simple structure, efficient assembly, and reliable locking.

[0033] This embodiment relates to a structural design for locking the movable part 20. As shown in the figure, one of the first locking member 32 and the base 10 is provided with a hook portion 12, and the other is provided with a locking portion 34. Specifically, for example, in this embodiment, the end of the first locking member 32 is formed with a locking portion 34, and the base 10 is provided with a matching hook portion 12. When the folding structure is unfolded or assembled, the first locking member 32 moves along a predetermined path, and the locking portion 34 aligns and contacts the hook portion 12 on the base 10. Subsequently, under the action of the first reset member 31, the locking portion 34 is locked inside the hook portion 12, thereby realizing the locking engagement between the first locking member 32 and the base 10.

[0034] In practical applications, the hook 12 can be a hook-shaped structure extending inward or outward, and the locking part 34 can be a protrusion, step, hole, or other structure that corresponds to the shape of the hook 12. By rationally designing the structural dimensions and positions of the hook 12 and the locking part 34, it can be ensured that the two can smoothly engage during assembly and are difficult to disengage after locking, thus guaranteeing the locking effect.

[0035] This embodiment effectively solves the technical problems of unreliable locking, easy loosening, and cumbersome operation in traditional locking structures by setting a hook 12 and a locking part 34 engaging between the first locking member 32 and the base 10. Specifically, this technical solution utilizes the snap-fit ​​engagement of the hook 12 and the locking part 34 to form a mechanical interlock after assembly, greatly enhancing the bonding strength between the first locking member 32 and the base 10, thereby improving the overall stability and safety of the structure and preventing locking failure due to external forces such as vibration and impact. At the same time, this structure is simple in design, enabling rapid assembly and unlocking, improving product assembly efficiency and ease of use, and reducing manufacturing and maintenance costs. Therefore, this embodiment achieves a stable lock between the first locking member 32 and the base 10 through the engagement of the hook 12 and the locking part 34, achieving the technical effects of simple operation, reliable locking, and high security.

[0036] The first locking element 32 and the base 10 can also be fixed to each other by means of pins, screws, etc.

[0037] This embodiment proposes an improved design to improve the stability and uniform force distribution of the first locking component 30. In this embodiment, the first locking member 32 and the base 10 are respectively provided with multiple hooks 12 and multiple locking parts 34. The multiple hooks 12 are distributed on one side or at multiple positions of the base 10, and the multiple locking parts 34 are distributed at corresponding positions on the first locking member 32. Each hook 12 cooperates with one locking part 34 to form a multi-point locking structure.

[0038] For example, the base 10 has two evenly spaced hooks 12 on one side along its length, and the first locking member 32 has two locking parts 34 at corresponding positions that are adapted to the structure of the hooks 12. During assembly, when the first locking member 32 moves to the predetermined position of the base 10, the two hooks 12 engage with the two locking parts 34 simultaneously, achieving multi-point simultaneous locking. The structure and dimensions of the multiple hooks 12 and locking parts 34 can be adjusted according to actual needs to meet different requirements for stress and structural strength.

[0039] This embodiment effectively solves the technical problems of uneven force distribution, easy loosening or rotation, and poor overall structural stability caused by single-point locking by increasing the number of hooks 12 and locking parts 34 to achieve multi-point engagement. The distributed structural design of multiple hooks 12 and multiple locking parts 34 allows the locking force to be evenly distributed at multiple locations, thereby significantly improving the overall strength and vibration and impact resistance of the locking structure. Even if some locking points are damaged or fail, the remaining locking points can still maintain basic locking function, significantly improving safety and reliability. In addition, multi-point locking can also prevent deflection or shaking between the first locking member 32 and the base 10, ensuring the structural accuracy and long-term stability after assembly. Therefore, this embodiment achieves multi-point uniform locking through the cooperation of multiple hooks 12 and multiple locking parts 34, significantly improving the stability and reliability of the locking structure, and achieving the technical effects of uniform structural force distribution, firm locking, and safe use.

[0040] This embodiment provides a structural design for limiting the rotation of the movable component 20. Specifically, an overlapping groove 25 is provided on the outer peripheral surface of the movable component 20. The overlapping groove 25 is a recessed groove structure along the outer peripheral surface of the movable component 20. When the movable component 20 rotates from the retracted state to the unfolded state, a part of the base 10 (such as the flange, protrusion, or edge of the base 10) can be inserted into or overlapped in the overlapping groove 25. At this time, the base 10 and the overlapping groove 25 are mechanically limited, thereby preventing the movable component 20 from continuing to rotate, and realizing the positioning and limiting of the movable component 20 at the required unfolding angle.

[0041] For example, the movable component 20 may be a flap, a pivot, or a hinged rod, with an annular or partial overlapping groove 25 machined on its outer circumferential surface. When the base 10 is assembled with the movable component 20, its structural design ensures that when the movable component 20 rotates to a predetermined position (such as the fully unfolded position), the edge of the base 10 naturally enters and embeds into the overlapping groove 25, achieving a locking and limiting action. In this way, the movable component 20 can no longer continue to rotate in the same direction, ensuring the reliability of the unfolded state and the safety of use.

[0042] This embodiment effectively solves the technical problems in the prior art, such as the difficulty in accurately limiting the movable part 20 after unfolding, and the ease with which it can continue to rotate due to external forces, leading to misoperation or damage, by setting an overlapping groove 25 on the outer peripheral surface of the movable part 20 and utilizing the overlapping relationship between the base 10 and the overlapping groove 25. The mechanical limiting cooperation between the overlapping groove 25 and the base 10 can automatically limit the movable part 20 when it rotates to the target angle, preventing the movable part 20 from continuing to rotate beyond the predetermined position. This not only ensures the stability of the movable part 20 during use, but also improves the safety and reliability of the device. At the same time, the structure is simple in design, easy to manufacture and assemble, does not add extra operating steps, and is easy to mass-produce. Therefore, this technical solution, through the limiting cooperation between the overlapping groove 25 and the base 10, achieves effective limiting of the movable part 20 in the unfolded state, achieving the technical effects of preventing excessive rotation, improving safety, and ensuring a simple and reliable structure.

[0043] Please see Figures 1 to 8 As shown, Figure 7 This is provided by the embodiment of the present utility model. Figure 4 Schematic diagram of the cross section along the IV-IV direction. Figure 8 This is provided by the embodiment of the present utility model. Figure 7 A magnified view of a portion of region C.

[0044] This embodiment relates to a structural design for limiting and locking a movable part 20, specifically including a second locking assembly 40. The second locking assembly 40 includes a mounting block 41, a second reset member 42, and a second locking member 43. The mounting block 41 is connected to the movable part 20, for example, fixed to a suitable position on the movable part 20 by screws or snap-fits. A through channel 411 is provided inside the mounting block 41, and the second reset member 42 (such as a spring) is assembled within the channel 411, providing elastic thrust. The second locking member 43 is columnar or pin-shaped, connected to the second reset member 42, and can move along the direction of the channel 411 under the elastic force of the reset member. A fixing hole 14 is provided on the base 10 to cooperate with the second locking member 43. When the movable part 20 is in a folded state, the mounting block 41 is positioned relative to the base 10, causing the second locking member 43 to automatically insert into the fixing hole 14 of the base 10 under the push of the second reset member 42, thereby locking the movable part 20 in the folded state. When the movable part 20 needs to be unfolded, the second locking part 43 is disengaged from the fixing hole 14 by external force or a special operation button. The second locking part 43 then retracts into the channel 411. At this time, there is no locking constraint between the movable part 20 and the base 10, and the movable part 20 can be unfolded smoothly. The second locking part 43 is separated from the fixing hole 14, avoiding obstruction to the unfolding action.

[0045] This technical solution integrates the second locking component 40 between the movable part 20 and the base 10, achieving automatic switching and reliable limiting of the movable part 20 in both folded and unfolded states. This effectively solves the technical problems in existing technologies where the movable part 20 is not securely locked in the folded state and is easily accidentally unfolded due to vibration or external force. Specifically, the second reset component 42 provides continuous elasticity to the second locking component 43, allowing it to automatically enter or exit the fixing hole 14 without manual intervention, thus automatically locking or releasing, improving operational convenience and structural safety. Furthermore, this structure is simple and compact, with mature manufacturing and assembly processes, and can adapt to various scenarios involving the combination of the movable part 20 and the base 10. Through this solution, the movable part 20 can be reliably fixed in the folded state, preventing misoperation or accidental unfolding; while when unfolding is required, it can be smoothly released, ensuring flexibility and safety in use, achieving the technical effects of structural stability, convenient operation, and reliable safety.

[0046] This embodiment relates to an installation structure that facilitates assembly and fixation. Specifically, the mounting block 41 includes a first block 412 and a second block 413. The first block 412 has a mounting groove for accommodating the second block 413, which is assembled into the mounting groove, forming a channel 411 between them. The movable part 20 has an assembly cavity 21 inside. In addition, an assembly port 22 communicating with the assembly cavity 21 is provided at one end of the movable part 20 along its length, facilitating the assembly of the mounting block 41. During assembly, the first block 412 and the second block 413 are inserted into the assembly cavity 21 through the assembly port 22 at the end of the movable part 20. The peripheral sidewalls of the assembly cavity 21 tightly clamp and fix the first block 412 and the second block 413, thereby achieving a stable connection between the mounting block 41 and the movable part 20. Through the above structural design, the first block 412 and the second block 413 can be reliably positioned within the assembly cavity 21 of the movable part 20.

[0047] This technical solution effectively solves the problems of cumbersome assembly, unstable fixing, and limited functional expansion when combining the mounting block 41 and the movable part 20 in the prior art. Firstly, by setting an assembly port 22 at one end of the movable part 20 and using the side wall of the assembly cavity 21 for clamping and fixing, the mounting block 41 component can be installed quickly and accurately, simplifying the assembly process and improving production efficiency. Secondly, the mating structure between the first block 412 and the second block 413 ensures the overall strength and stability of the mounting block 41, avoiding the risk of component loosening or falling off, and improving the product's durability and reliability. Furthermore, the channel 411 formed by the mounting groove on the first block 412 and the second block 413 after assembly provides space support for the subsequent assembly of other functional parts 442, enhancing the scalability of the structure. Therefore, this technical solution, through reasonable structural design, achieves an efficient and stable connection between the mounting block 41 and the movable part 20, significantly improving assembly convenience and structural safety, and meeting the technical requirements for efficient assembly and secure connection in practical applications.

[0048] This embodiment relates to an improved structure of a second locking component 40, characterized in that the second locking component 40 further includes a safety helmet 44. Specifically, the safety helmet 44 is designed as a structural component capable of engaging with the fixing hole 14 of the base 10. During assembly, the safety helmet 44 is assembled into the fixing hole 14 of the base 10 by means of insertion, screwing, or snapping, and achieves a reliable connection with the base 10. The safety helmet 44 covers and protects the opening of the fixing hole 14 after the second locking member 43 is inserted into the fixing hole 14, thereby preventing foreign objects from entering the fixing hole 14 and also preventing the second locking member 43 from falling off or malfunctioning due to improper operation. The structure of the safety helmet 44 can be optimized according to actual needs, such as by setting a limiting step, reinforcing ribs, or an anti-slip structure to improve its connection strength with the base 10 and its service life.

[0049] This technical solution effectively solves the safety hazards and reliability problems caused by the exposed fixing hole 14 in the prior art. Firstly, by adding a safety cap 44 to the fixing hole 14, external foreign objects such as dust, debris, or liquids can be effectively prevented from entering the fixing hole 14, avoiding obstruction or malfunction of the locking mechanism due to foreign object accumulation, thereby improving the operational reliability and stability of the second locking assembly 40. Secondly, the safety cap 44 protects and reinforces the opening of the fixing hole 14, preventing wear, deformation, or damage to the opening due to long-term use, thus improving the product's durability. Furthermore, the safety cap 44 also prevents the locking mechanism from accidentally falling off or popping out during operation, ensuring safety during use. In summary, this technical solution, by adding a safety cap 44 to the second locking assembly 40, achieves effective protection of the fixing hole 14 and improves the safety of the locking mechanism, significantly enhancing the overall structural protection performance and operational reliability, thereby achieving the technical effects of structural safety, convenient operation, and long-term stability.

[0050] This embodiment provides a novel safety helmet 44 structure, which includes a deformable part 441 and a functional part 442. The functional part 442 is connected to the deformable part 441, and the two together form a deformable cavity 443. The functional part 442 is positioned towards the second locking member 43 to abut against it. The distal end of the deformable part 441 is connected to the base 10, allowing the entire safety helmet 44 to be securely mounted on the base 10. In use, when it is necessary to release the second locking member 43, the operator only needs to press the functional part 442 of the safety helmet 44. Under the action of external force, the functional part 442 will move inward, thereby generating greater resistance to the second locking member 43, causing it to gradually separate from the fixing hole 14, achieving rapid release of the second locking member 43. After the operation is completed and the external force is removed, due to the good elasticity or recoverable deformation characteristics of the deformable part 441, the deformable part 441 will automatically return to its original shape, thereby driving the functional part 442 back to its initial position.

[0051] This technical solution achieves efficient control of the second locking member 43 by designing the safety helmet 44 to include a deformable part 441 and a functional part 442, which together form a deformable cavity 443. On one hand, the functional part 442 can directly hold and release the second locking member 43. The user only needs to press the functional part 442 to easily separate the locking member without the need for additional tools, greatly simplifying the operation process and improving work efficiency. On the other hand, relying on the elastic properties of the deformable part 441, the functional part 442 can be automatically pushed back to its original position after the external force is removed, achieving rapid system reset.

[0052] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0053] Furthermore, when an element is referred to as 'fixed to' or 'set on' another element, it may be directly attached to that element, or there may be other intervening elements between them. When an element is referred to as 'connected to' another element, it can be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0054] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, the designation of features such as "first" and "second" can either explicitly express or imply the presence of at least one such feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
