Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically, to a surface protection mechanism for a handheld PDA. Background Technology

[0002] The risk of drops. These devices are typically designed to be lightweight and portable, but precisely because of their small size and light weight, they are easily damaged by accidental slips, bumps, or drops during user operation. Although many PDA devices are equipped with robust casings and some shock resistance, these protective measures are often not entirely sufficient to prevent serious damage from drops due to friction and impacts during long-term use. Especially in high-intensity use environments, such as industrial sites, hospitals, or outdoor work, drop accidents are more frequent, leading to limited or complete malfunction of the device and causing significant inconvenience to users.

[0003] However, existing PDA devices still have significant shortcomings in terms of protective technology. Although some brands and models have launched devices with drop, water, and dust resistance, these protective measures often cannot cover all possible usage scenarios. For example, in highly complex or extreme environments, traditional protective designs may not be effective in dealing with stronger impacts or irregular drop trajectories. Furthermore, while some handheld PDA devices prioritize aesthetics in their design, their drop resistance may not be adequate. This lack of protective design often results in users incurring high repair costs or the financial burden of replacing the device in the event of an accidental drop. Therefore, improving the drop resistance of devices and ensuring their safe use in various environments has become an important issue in current technological development. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a surface protection mechanism for a handheld PDA, which has the following beneficial effects:

[0017] This handheld PDA's surface protection mechanism, through its innovative airbag system and mechanical adjustment mechanism, effectively improves the device's impact resistance during drops, providing significant protection. First, the airbag system has two airbags on both sides of the device. When the device is dropped or subjected to external impact, the airbags can react quickly, mitigating the direct impact of the external force through gas compression and transfer. This airbag structure, by increasing the contact area with the ground, can effectively disperse the impact force, reduce damage to the device, and ensure its safety. The gas flow mechanism between the airbags ensures that when one airbag is impacted, the other airbag automatically absorbs and adjusts the pressure, thus forming a continuous protection process.

[0018] Secondly, the spring system and adjustable pressure mechanism in the equipment further enhance the flexibility and adaptability of the protection. When the equipment is subjected to drops of varying intensities, the adjustment mechanisms at the top and bottom can automatically adjust the pressure according to the magnitude of the external force. This adjustment is achieved through the deformation of the springs, providing flexible protection in different industry environments and adapting to various working intensities. By adjusting the length of the internal springs, the trigger pressure of the protection mechanism can be precisely controlled, ensuring that the equipment remains stable even under significant impact. In addition, by rotating the magnetic ring, users can easily adjust the spring stiffness coefficient to achieve the ideal protective effect. This adjustment function further enhances the versatility of the equipment and the user's operating experience.

[0019] Overall, this protective mechanism design not only effectively reduces equipment damage in drop accidents but also provides personalized protection adjustments based on user needs. Whether in high-intensity work environments or during daily use, this innovative protective system significantly improves equipment durability and safety, providing users with more reliable protection.

[0029] Please see Figure 1-5A surface protection mechanism for a handheld PDA includes a housing 1, on which a protective mechanism is provided. The protective mechanism includes two airbags 2, which are respectively installed on both sides of the housing 1. Each airbag 2 is connected to a vertical tube 3. A vertical groove 4 is opened on the housing 1, and the vertical tube 3 is installed in the vertical groove 4. A middle tube 5 is coaxially arranged between the two vertical tubes 3. Connecting sleeves 6 are provided at both ends of the middle tube 5, and the two connecting sleeves 6 are respectively connected to the two vertical tubes 3. A top sleeve 17 and a bottom sleeve 18 are respectively installed on the inner wall of the middle tube 5. The top sleeve 17 and the bottom sleeve 18 are coaxially arranged. A top rod 7 is slidably installed in the top sleeve 17, and a bottom rod 19 is slidably installed in the bottom sleeve 18. A middle rod 20 is installed between the top rod 7 and the bottom rod 19. Round corners 8 are opened on the top rod 7 and the bottom rod 19. Round grooves 9 are opened on the top sleeve 17 and the bottom sleeve 18. The intermediate tube 5 has a threaded ring 10 inside, and a magnetic ring 11 is rotatably mounted on the outer wall of the intermediate tube 5. Multiple magnetic rods 12 are mounted on the inner wall of the threaded ring 10. Multiple anti-slip grooves 13 are evenly spaced on the outer wall of the magnetic ring 11. A spring 14 is provided between the top rod 7 and the bottom rod 19. Multiple intermediate discs 15 are evenly spaced on the spring 14. Each intermediate disc 15 has a through groove 16. The multiple through grooves 16 are slidably connected to the intermediate rod 20. An inner ring 21 is installed inside the threaded ring 10 and is threadedly connected to the intermediate disc 15.

[0030] In this embodiment, the handheld operating terminal needs to be protected on its exterior during use. Two airbags 2 are set to protect the safety of the housing 1. When a drop occurs, one airbag 2 will pressurize the gas into the other airbag 2, thereby increasing the contact area and reducing the impact force, thus ensuring the safety of use. When one of the airbags 2 is impacted, the air pressure will increase, which will then provide pressure to the top rod 7, and compress the spring 14 between the top rod 7 and the inner ring 21. This will release the seal between the top rod 7 and the top sleeve 17, allowing the gas to circulate. The bottom sleeve 18 and the bottom rod 19 will also undergo the corresponding process, thus completing the adjustment process.

[0031] More specifically, when it is necessary to change the opening pressure between the top sleeve 17 and the top rod 7, it is only necessary to change the length of the spring 14 between the top rod 7 and the inner ring 21 to change the corresponding stiffness coefficient. Therefore, the opening pressure can be changed. The rotation of the magnetic ring 11 can drive the magnetic rod 12 to rotate accordingly. Since the threaded ring 10 is threadedly connected to the intermediate tube 5, it will cause it to slide on the intermediate tube 5. And the inner disc can be threadedly connected to different intermediate discs 15 as it rotates, thereby changing the stiffness coefficient of the spring 14, and thus completing the adjustment process.

[0032] In summary, during the use or operation of the overall equipment: the handheld operating terminal needs external protection. Two airbags 2 are used to protect the shell 1. In the event of a drop, one airbag 2 will pressurize the gas into the other airbag 2, increasing the contact area and reducing the impact force, thus ensuring safety. When one airbag 2 is impacted, the air pressure will increase, which will then provide pressure to the top rod 7, compressing the spring 14 between the top rod 7 and the inner ring 21. This will release the seal between the top rod 7 and the top sleeve 17, allowing the gas to circulate. The bottom sleeve and bottom rod 19 will also undergo corresponding processes, thus completing the adjustment process.

[0033] When it is necessary to change the opening pressure between the top sleeve 17 and the top rod 7, it is only necessary to change the length of the spring 14 between the top rod 7 and the inner ring 21 to change the corresponding stiffness coefficient. Therefore, the opening pressure can be changed. The rotation of the magnetic ring 11 can drive the magnetic rod 12 to rotate accordingly. Since the threaded ring 10 is threadedly connected to the intermediate tube 5, it will slide on the intermediate tube 5. And the inner disc can be threadedly connected to different intermediate discs 15 as it rotates, thereby changing the stiffness coefficient of the spring 14, and thus completing the adjustment process.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
