Description

Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to an adaptive spring-loaded visor type variable jaw guard helmet. Background Technology

[0002] Drivers of motor vehicles, boats, and aircraft must wear helmets to protect their heads while operating vehicles. A typical helmet consists of a main shell, visor, visor, and chin guard, among other components. The chin guard provides effective protection for the driver's chin and other areas in the event of an accidental collision.

[0003] During use, drivers sometimes need to flip up the chin guard, allowing it to extend across the visor and fit snugly at the back of the helmet. At this point, the helmet transforms from a full-face helmet to a half-face helmet. If necessary, the chin guard can be flipped back from the half-face position across the visor, returning to a full-face helmet configuration. Helmets that can flexibly switch between full-face and half-face configurations are called variable chin guard helmets. They cleverly combine the high safety of a full-face helmet with the flexibility of a half-face helmet, making them highly popular among drivers.

[0004] While variable chin guard helmets, combining the safety of a full-face helmet with the flexibility of a half-face helmet, are popular among riders, they still have significant shortcomings in practical use. When a rider needs to flip the chin guard to switch between a full-face and half-face helmet configuration, the operation is quite laborious. This means that in emergency situations requiring a quick change in helmet shape, the rider cannot complete the operation in time, greatly reducing the user experience.

[0005] To effectively solve this problem, we propose an adaptive spring-loaded visor type variable jaw guard helmet. Utility Model Content

[0006] The purpose of this invention is to provide an adaptive spring-loaded variable chin guard helmet, which has the advantages of convenient operation, reliable positioning, and adaptive reset air, and solves the technical problems of traditional variable chin guard helmets such as difficult operation for switching states, slow response in emergency situations, and insufficient structural stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adaptive spring-loaded visor type variable chin guard structure helmet, including a helmet body, a chin guard assembly and a positioning assembly, wherein the helmet body is provided with a mounting ring, and the mounting ring is provided with a first positioning hole and a second positioning hole;

[0008] The chin guard assembly is rotatably connected to the helmet body via a pivot, and the chin guard assembly can switch between full-face helmet and half-face helmet modes;

[0009] The positioning component includes a pin and an elastic element. The pin can be inserted into the first positioning hole or the second positioning hole under the action of the elastic element to fix the chin guard component in a full-face helmet state or a half-face helmet state.

[0010] Preferably, the positioning assembly further includes a mounting bracket for supporting and mounting the pin and the elastic element.

[0011] In the design, the mounting bracket added to the positioning component provides stable support and installation for the pin and elastic element, ensuring that the pin is accurately inserted into the first or second positioning hole under the action of the elastic element, thereby enhancing the structural stability and reliability of the positioning component and providing a solid foundation for the stable fixation of the chin guard component in full-face and half-face helmet states.

[0012] Preferably, the jaw protection assembly includes a jaw protection plate and a connecting frame, the connecting frame being connected to the rotating shaft, and the jaw protection plate being fixedly connected to the connecting frame.

[0013] In the design, the chin guard assembly adopts a combination design of chin guard plate and connecting frame. The connecting frame is connected to the rotating shaft, and the chin guard plate is fixed to the connecting frame, which realizes the flexible rotation of the chin guard assembly and the effective function of the chin guard plate in protecting the driver's chin, making the chin guard assembly stable and reliable when switching between different states.

[0014] Preferably, the helmet body is also provided with ventilation holes for ventilation and air permeability.

[0015] The helmet's design incorporates ventilation holes, allowing for airflow inside and effectively alleviating the wearer's stuffiness and discomfort, significantly improving comfort and making it particularly suitable for extended work sessions.

[0016] Preferably, the jaw protector assembly further includes a torsion spring structure, which assists in the flipping and resetting of the jaw protector assembly.

[0017] The torsion spring structure includes a torsion spring body and a torsion spring positioning hole. The torsion spring body is mounted on the helmet body, and the torsion spring positioning hole is disposed on the connecting frame. The torsion spring positioning hole is used to install and position the torsion spring body.

[0018] In the design, the chin guard assembly incorporates a torsion spring structure. By utilizing the cooperation between the torsion spring body and the torsion spring positioning hole, the chin guard assembly can be flipped and reset, making the chin guard assembly switch between full-face and half-face helmet states more smoothly, reducing the difficulty of operation, and enabling a rapid response in emergency situations.

[0019] Preferably, the positioning assembly further includes a pull rod, which is fixedly installed with the pin. The pull rod is used to manually operate the pin to release or fix the pin in the first positioning hole or the second positioning hole.

[0020] In the design, the added lever and pin of the positioning component are fixedly installed, which realizes the manual operation of the pin. The wearer can easily release or fix the pin through the lever. The operation is intuitive and convenient, and meets the needs of switching helmet status in different scenarios.

[0021] Preferably, the connecting frame is further provided with positioning mounting holes for installing and fixing the positioning component.

[0022] In the design, the positioning mounting holes on the connecting frame enable convenient installation and fixation of the positioning components, which not only ensures the accuracy of the positioning component installation, but also facilitates the later maintenance and replacement of the positioning components, thereby improving the overall maintainability of the helmet.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This invention features a chin guard assembly that is rotatably connected to the helmet body via a pivot, allowing the chin guard assembly to easily switch between full-face and half-face helmet modes. This achieves convenient operation and solves the problem of laborious operation when switching modes in traditional variable chin guard helmets. Users only need to rotate the chin guard assembly to complete the mode switching without complicated operations.

[0025] This invention features a positioning component, including a pin and an elastic element. The pin, under the action of the elastic element, can be inserted into a first or second positioning hole to secure the chin guard assembly in either a full-face or half-face helmet configuration, achieving reliable positioning. In both full-face and half-face helmet configurations, the pin is firmly inserted into the positioning hole under the action of the elastic element, preventing accidental movement of the chin guard assembly. This solves the problem of insufficient stability in traditional helmet structures and ensures the user's safety in different situations.

[0026] This invention, through the cooperation of an elastic element and a pin, allows the pin to quickly insert into the corresponding positioning hole during the transition of the chin guard assembly, achieving an adaptive reset effect. In emergency situations, it can quickly respond and complete the state transition, solving the problem of slow response in emergency situations with traditional variable chin guard helmets. The elastic element enables the pin to be quickly positioned, improving safety and timeliness of use. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0034] like Figures 1 to 5 As shown, one embodiment of the present invention is provided: an adaptive spring-loaded visor type variable chin guard structure helmet, including a helmet body 1, a chin guard assembly 4 and a positioning assembly 2. The helmet body 1 is provided with a mounting ring 12, and the mounting ring 12 is provided with a first positioning hole 121 and a second positioning hole 122.

[0035] The chin guard assembly 4 is rotatably connected to the helmet body 1 via a pivot 3, and the chin guard assembly 4 can switch between full-face helmet and half-face helmet modes.

[0036] The positioning component 2 includes a pin 21 and an elastic element 23. The pin 21 can be inserted into the first positioning hole 121 or the second positioning hole 122 under the action of the elastic element 23 to fix the chin guard component 4 in the full-face helmet state or the half-face helmet state.

[0037] Specifically, by setting the chin guard assembly 4 to be rotatably connected to the helmet body 1 via the pivot 3, the chin guard assembly 4 can be easily switched between full-face and half-face helmet states, achieving the effect of convenient operation and solving the problem of laborious operation when switching states in traditional variable chin guard helmets. Users only need to rotate the chin guard assembly 4 to complete the state switching without complicated operations.

[0038] By setting a positioning component 2, which includes a pin 21 and an elastic element 23, the pin 21 can be inserted into the first positioning hole 121 or the second positioning hole 122 under the action of the elastic element 23, so as to fix the chin guard component 4 in the full-face helmet position or the half-face helmet position, achieving a reliable positioning effect. In the full-face helmet or half-face helmet position, the pin 21 can be firmly inserted into the positioning hole under the action of the elastic element 23, preventing the chin guard component 4 from moving accidentally, solving the problem of insufficient stability of traditional helmet structures, and ensuring the safety of users in different situations.

[0039] By cooperating with the elastic element 23 and the pin 21, the elastic element 23 assists the pin 21 in quickly inserting into the corresponding positioning hole when the chin guard assembly 4 changes state, achieving an adaptive reset effect. In emergency situations, it can quickly respond and complete the state transition, solving the problem of slow response in emergency situations in traditional variable chin guard helmets. The elastic element 23 enables the pin 21 to be quickly positioned, improving the safety and timeliness of use. Example 2

[0040] To achieve stable support for the positioning components and a modular design for the jaw protection components, such as Figure 2 and Figure 4 As shown, in this embodiment, the positioning component 2 further includes a mounting bracket 22, which is used to support and install the pin 21 and the elastic element 23.

[0041] Specifically, the mounting bracket 22 added to the positioning component 2 provides stable support and installation for the pin 21 and the elastic element 23, ensuring that the pin 21 is accurately inserted into the first positioning hole 121 or the second positioning hole 122 under the action of the elastic element 23, thereby enhancing the structural stability and reliability of the positioning component 2 and providing a solid foundation for the stable fixation of the chin guard component 4 in full-face and half-face helmet states.

[0042] Furthermore, the jaw protection assembly 4 includes a jaw protection plate 41 and a connecting frame 42. The connecting frame 42 is connected to the rotating shaft 3, and the jaw protection plate 41 is fixedly connected to the connecting frame 42.

[0043] Specifically, the chin guard assembly 4 adopts a combination design of chin guard plate 41 and connecting frame 42. The connecting frame 42 is connected to the rotating shaft 3, and the chin guard plate 41 is fixed to the connecting frame 42, which realizes the flexible rotation of the chin guard assembly 4 and the effective function of the chin guard plate 41 in protecting the driver's chin, making the chin guard assembly 4 stable and reliable when switching between different states.

[0044] Furthermore, the helmet body 1 is also provided with ventilation holes 11 for ventilation and air permeability.

[0045] Specifically, the ventilation holes 11 on the helmet body 1 enable ventilation inside the helmet, effectively improving the wearer's stuffiness and discomfort, and greatly enhancing the comfort of wearing the helmet, especially suitable for long-term work scenarios. Example 3

[0046] To achieve adaptive flipping and rapid state switching of the jaw protector assembly, such as Figure 3 and Figure 5 As shown, in this embodiment, the jaw protection assembly (4) also includes a torsion spring structure, which is used to assist the jaw protection assembly (4) in flipping and resetting;

[0047] The torsion spring structure includes a torsion spring body 13 and a torsion spring positioning hole 421. The torsion spring body 13 is mounted on the helmet body 1, and the torsion spring positioning hole 421 is provided on the connecting frame 42. The torsion spring positioning hole 421 is used to install and position the torsion spring body 13.

[0048] Specifically, the chin guard assembly 4 incorporates a torsion spring structure. By utilizing the cooperation between the torsion spring body 13 and the torsion spring positioning hole 421, the chin guard assembly 4 is able to achieve the auxiliary function of flipping and resetting. This makes the chin guard assembly 4 smoother when switching between full-face and half-face helmet states, reduces the difficulty of operation, and enables a rapid response in emergency situations.

[0049] Furthermore, the positioning assembly 2 also includes a pull rod 24, which is fixedly installed with the pin 21. The pull rod 24 is used to manually operate the pin 21 to release or fix the pin 21 in the first positioning hole 121 or the second positioning hole 122.

[0050] Specifically, the added lever 24 of the positioning component 2 is fixedly installed with the pin 21, which enables manual operation of the pin 21. The wearer can easily release or fix the pin 21 through the lever 24. The operation is intuitive and convenient, meeting the needs of switching helmet states in different scenarios.

[0051] Furthermore, the connecting bracket 42 is also provided with a positioning mounting hole 422, which is used to install and fix the positioning component 2.

[0052] Specifically, the positioning mounting hole 422 provided in the connecting bracket 42 enables convenient installation and fixation of the positioning component 2, which not only ensures the accuracy of the installation of the positioning component 2, but also facilitates the later maintenance and replacement of the positioning component 2, thereby improving the overall maintainability of the helmet.

[0053] When using this invention, the helmet body 1 is worn on the head, and the ventilation holes 11 can ensure ventilation inside the helmet, improving wearing comfort.

[0054] When you need to switch from a full-face helmet to a half-face helmet:

[0055] Manually operate the lever 24 to make the pin 21 overcome the force of the elastic element 23 and pull it out of the first positioning hole 121.

[0056] Rotate the chin guard assembly 4. At this time, the torsion spring body 13 in the torsion spring structure cooperates with the torsion spring positioning hole 421 to assist the chin guard assembly 4 in flipping. The chin guard assembly 4 rotates around the rotating shaft 3, changing from the full-face helmet state to the half-face helmet state.

[0057] When the chin guard assembly 4 is flipped to the half-helmet position, the pull rod 24 is released, and the pin 21 is inserted into the second positioning hole 122 under the action of the elastic element 23, thus fixing the chin guard assembly 4 in the half-helmet position.

[0058] When you need to switch from a half-helmet configuration to a full-face helmet configuration:

[0059] Manually operate the lever 24 again to make the pin 21 overcome the force of the elastic element 23 and pull it out of the second positioning hole 122.

[0060] Rotate the chin guard assembly 4, and the torsion spring structure assists the chin guard assembly 4 in flipping to the full-face helmet position. The chin guard assembly 4 rotates around the pivot 3.

[0061] When the chin guard assembly 4 is flipped to the full-face helmet position, the lever 24 is released, and the pin 21 is inserted into the first positioning hole 121 under the action of the elastic element 23, thus fixing the chin guard assembly 4 in the full-face helmet position.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
