On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0032] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0033] At present, from the perspective of market development, the application of electronic products is becoming more and more extensive, especially computer devices that require peripheral devices, such as desktop computers, portable computers, and tablet computers. With the popularization of mobile computing devices and the growth of portability requirements, the mouse, as an important component of computer input devices, has become a focus of user attention for its portability. A type of mouse design that aims to optimize portability has emerged in the current market. This type of design achieves the goal of compact carrying by significantly reducing the size of the mouse or adopting an innovative special-shaped structure. These portable mice are widely used in laptops, tablet computers, and other lightweight work scenarios to meet the needs of users for efficient operation anytime, anywhere.

[0034] The inventor of the present application has found that the mouse that has been miniaturized through physical shape changes has brought challenges in ergonomic design. Since the reduced size may not be able to adapt to the curve and force distribution of the natural grip of the human hand, long-term use of such a small mouse will cause the user's hand fatigue to increase and the operating comfort to drop significantly. In addition, the mechanical button structure is easily damaged when it is impacted by external forces or collides with other objects during carrying, thereby affecting the functional stability and service life of the mouse. In order to solve the above technical problems at the same time, the following technical solutions need to be implemented.

[0036] Specifically, in the technical solution adopted by the present application, the shell 1 is a substrate for carrying the first structure. When the first structure is in the first form, the shell 1 can be used as a substrate for accommodating the first structure, so that the input device is in the volume of the shell 1 when not in use; and when the first structure is in the second form, the shell 1 can be used as a head structure of the input device, so that the input device can be used, specifically, gas is filled in the first structure to make its structure expand and change, and it can be used to support human tissue, such as: human hand. The technical point of the present application is that a sensing module is provided on the input device, which is respectively distributed on the shell 1 and the first structure and other target structures that can be inflated and expanded. The corresponding indication signal can be determined according to the pressure size and the pressure change of the first structure and / or the target structure, so that when the input device of the present application is a mouse, the first air cushion 11 and the second air cushion 12 can be used to replace the mechanical structure of the left / right button on the mouse, and the indication operation acting on the first air cushion 11 and the second air cushion 12 is conveyed through pressure sensing as an indication signal output to the electronic device.

The input device is also equipped with a printed circuit board 9, which is used to receive and process instruction signals and then send them to the target electronic device, so that various indication operations can be realized through pressure sensing.

[0037] It should be noted that the keys that can be triggered on the input device in the present application are replaced by pressure areas with pressure sensing characteristics. Therefore, the input device can be stored and unfolded, and because the first structure and / or the target structure have gas support inside when in use, it can prevent the pressure area from malfunctioning or failing due to collision.

[0039] Specifically, in the technical solution adopted by the present application, a first air cushion 11 and a second air cushion 12 in a normalized expansion state are provided in the input device. It can be understood that the first air cushion 11 and the second air cushion 12 are irrelevant to the storage and expansion of the first structure. In one embodiment, the first air cushion 11 and the second air cushion 12 can be arranged on the housing 1, preferably on the upper surface of the housing 1, to form a set of pressure areas on the input device. When in use, the first air cushion 11 and / or the second air cushion 12 can be pressed to change the gas pressure inside it, and the sensing module determines and sends a corresponding indication signal by sensing the pressure change; the first air cushion 11 and the second air cushion 12 can be designed as an integrated design, but the space containing the gas inside it needs to be separated. In a preferred embodiment of the present application, the first air cushion 11 and the second air cushion 12 can be used as the left / right key command in the input device. And pressing the first air cushion 11 and the second air cushion 12 at the same time can also generate other commands, which can be set to slide up and down the page or adjust the display ratio according to personal habits.

In the present application, the left key instruction can be defined as the first indication signal, and the right key instruction can be defined as the second indication signal, wherein the first sensing component 13 senses the change in the first air cushion 11 and transmits it to the printed circuit board 9, and then it is processed into the first indication signal by the printed circuit board 9; the second sensing component 14 senses the change in the second air cushion 12 and transmits it to the printed circuit board 9, and then it is processed into the second indication signal by the printed circuit board 9.

[0043] Specifically, in the technical solution adopted by the present application, in the first embodiment of the first structure proposed in the present application, the first structure includes at least one first airbag 3, the first airbag 3 can be filled and discharged with gas medium through the air nozzle component 6 configured in the shell 1, when the gas medium is discharged from the first airbag 3, it is in a first state that can be accommodated in the cavity of the shell 1, and when there is sufficient gas medium in the first airbag 3, it is in a second state that can support human tissue after expansion. When the first airbag 3 is in the first state, it can be loaded into the cavity in the shell 1, so that the first airbag 3 can be accommodated in the shell 1, so as to reduce the volume of the portable input device; when the first airbag 3 is in the second state, it can support human tissue, so that the input device can be used normally, and its operation difficulty will not be increased and the ergonomic shape of the input device will not be affected.

[0044] Further, see Figures 1 to 3 As shown, in some embodiments, the first structure also includes: a second airbag 4, in which a gas medium can be filled and discharged, the second airbag 4 is isolated from the internal space of the first airbag 3, and is located on one side of the first airbag 3; the sensing module determines the third indication signal by sensing the pressure change in the second airbag 4.

[0045] Specifically, in the technical solution adopted by the present application, the second implementation of the first structure is proposed in the present application. Compared with the first implementation, the second airbag 4 is further included on the basis of the first structure formed by the first airbag 3. Similar to the first airbag 3, the second airbag 4 also has the function of filling and discharging the gas medium into the interior thereof through the air nozzle component 6, that is, the second airbag 4 can also be accommodated in the cavity of the housing 1. The internal spaces of the second airbag 4 and the first airbag 3 are independent of each other. In a further preferred embodiment of the second implementation, the second airbag 4 can be arranged on one side of the first airbag 3. The sensing module can determine the third indication signal acting on the target electronic device by sensing the pressure change in the second airbag 4.

[0046] Further, see Figure 4 As shown, in some embodiments, the sensing module includes: a third sensing component 41 , which is disposed in the inner space of the second airbag 4 and is used to sense the pressure change in the second airbag 4 .

[0047] Specifically, in the technical solution adopted by the present application, in the second implementation of the first structure, the sensing module also includes a third sensing component 41, which can be a pressure sensor configured in the second airbag 4 and connected to the printed circuit board 9, so as to be able to sense the pressure change of the gas medium in the second airbag 4 and transmit it to the printed circuit board 9 for processing, and the printed circuit board 9 processes the pressure change signal into a third indication signal and sends it to the target electronic device. In one embodiment, the first air cushion 11 and the second air cushion 12 complete the corresponding left / right button indication command of the mouse, and the indication command completed by the second airbag 4 and the third sensing component 41 can be set according to the industry needs.

[0048] Further, see Figures 1 to 3 As shown, in some embodiments, the first structure also includes: a third airbag 5, which is located on the side of the first airbag 3 away from the second airbag 4, and the third airbag 5 is isolated from the internal space for storing gas medium in the first airbag 3 and the second airbag 4 respectively; the sensing module determines the fourth indication signal by sensing the pressure change in the third airbag 5.

[0049] Further, see Figure 4 As shown, in some embodiments, the sensing module further includes: a fourth sensing component 51 , which is disposed in the inner space of the third airbag 5 and is used to sense pressure changes in the third airbag 5 .

[0050] Specifically, in the technical solution adopted by the present application, in a preferred embodiment of the present application, the third airbag 5 can be arranged on the side of the first airbag 3 away from the second airbag 4 to form left / right side buttons on both sides of the first airbag 3, and the internal space of the third airbag 5 is separated from the internal space of the first airbag 3 and the second airbag 4, respectively, and has the function of filling and discharging gas medium through the air nozzle component 6, so that the sensing module can determine the fourth indication signal acting on the target electronic device based on the pressure change in the third airbag 5.

[0051] In the preferred embodiment of this implementation mode, similar to the above-mentioned embodiment, the fourth sensing component 51 also adopts a pressure sensor, and the fourth indication signal can also set the indication command that the third airbag 5 can complete according to the different needs of the industry, so that the input device has more shortcut instructions and combined triggering methods.

[0052] Further, see Figure 4 As shown, in some embodiments, the sensing module includes: a fifth sensing component 31, which is arranged in the internal space of the first airbag 3 to be able to sense the pressure change in the first airbag 3 as a fifth indication signal.

[0053] Specifically, in the technical solution adopted by the present application, the fifth sensing component 31 is configured in the first airbag 3 and connected to the printed circuit board 9. Its function and the fifth indication signal that can be transmitted are the same as those in the above embodiment, so no detailed description is given. It should be noted that the input device of the present application currently provides five pressure areas, and each pressure area can respectively realize different indication commands acting on the target electronic device, and in the embodiment of the present application, it can also be used in combination through programming. For example, the pressure area composed of the first air cushion 11 and the second air cushion 12 is pressed at the same time, or the first air cushion 11, the second air cushion 12 and the first airbag 3 are pressed in combination, or the second airbag 4 and the third airbag 5 are pressed in combination, etc., that is, all the pressing areas on the input device can be freely combined to form different pressure changes, and different specific indication commands can be issued to the target electronic device through the printed circuit board 9. It can be freely set according to different needs. For example, squeezing the first airbag 3 to make the fifth sensor component 31 react can be a downward scrolling instruction for controlling the electronic device page, while triggering the pressure area of ​​the first air cushion 11 and the second air cushion 12 at the same time can be a upward scrolling instruction for controlling the electronic device page, that is, the input device of the present application can complete the upward and downward scrolling instructions of the electronic device page through the first air cushion 11, the second air cushion 12 and the first airbag 3. It should be noted that other airbags can also be set with the required functional combination in this way, and the present application does not set any restrictions on this function.

[0054] In some embodiments, an anti-skid pad 7 can also be set on both sides of the rear of the first airbag 3 on the first structure and / or on the second airbag 4 and the third airbag 5. The outer surface of the anti-skid pad 7 is set to a granular structure or a rough surface to increase the friction between the first structure and human tissue.

[0055] Further, see Figures 1 to 4 As shown, in some embodiments, it further includes: a cover body 2, which is arranged on a side of the first structure away from the shell 1, and is used to cover the shell 1 when the first structure is in the first form.

[0056] Specifically, in the technical solution adopted by the present application, the cover body 2 is embedded or bonded to the outer surface of the first airbag 3. During use, when the first airbag 3 is in the first form, and after the first airbag 3 is stored in the cavity of the shell 1, the cover body 2 can cover the opening of the cavity to complete the storage operation. In the embodiment of the present application, since the cover body 2 is a hard material, the internal area of ​​the first airbag 3 covered by the cover body 2 can be configured with the battery component 8 of the mouse, and the input device in the storage state can stand on a flat surface or a charging device with a charging groove through the cover body 2 to facilitate wireless charging.

[0057] In some embodiments, when the first structure is composed of only the first airbag 3, the air nozzle component 6 has at least one air inlet and an air outlet, and the air inlet is preferably arranged on the side of the housing 1 away from the first airbag 3, and the air outlet is connected to the internal space of the first airbag 3. When the first structure is composed of the first airbag 3 and the second airbag 4, the air nozzle component 6 is a two-way component with one air inlet and two air outlets, and the two air outlets are respectively connected to the first airbag 3 and the second airbag 4 separated from each other in the internal space. When the first structure is composed of the first airbag 3, the second airbag 4 and the third airbag 5, the air nozzle component 6 is a three-way component with one air inlet and one air outlet, and the two outlets are respectively connected to the first airbag 3, the second airbag 4 and the third airbag 5 separated from each other in the internal space. In this embodiment, the operation of filling and discharging the gas medium into the first airbag 3 and / or the second airbag 4 and / or the third airbag 5 is realized through the air nozzle component 6.

[0058] After adopting the input device of the present application, since the input device integrates an adjustable air cushion / air bag system with inflation and deflation, the system can be adaptively adjusted according to the user's hand size and usage scenario. In the carrying state, the exposed pressure area is also composed of an air cushion with a gas medium inside, which greatly improves the device's anti-collision ability and effectively avoids the problem that traditional hard material input devices are easily damaged during carrying. When the input device enters the use state, the built-in air bag will be inflated according to the preset or user-customized settings, thereby forming an ergonomic curved surface, providing better grip comfort and support.

[0059] Through the inflation and deflation function of the airbag, the input device can be reduced in size when carried, reduce space occupied, and enhance the protection against accidental impacts and bumps, thereby extending the service life of the input device. The dynamically adjustable airbag structure can adapt to the holding habits and hand shapes of different users, provide a support surface that fits the palm more closely, reduce fatigue after long-term use, and significantly improve the operating comfort. The use of pressure sensing technology to replace traditional mechanical buttons allows the input device to show higher accuracy and response speed when performing fine control tasks, especially in the fields of graphic design, film and television editing, etc., it can reach or even exceed the work efficiency of traditional input devices, and meet the stringent requirements of professionals for high-precision control. In short, the airbag pressure sensing input device proposed in the utility model not only innovates the design concept and technical path of the input device, but also realizes the effective combination of portability, ergonomic characteristics and control accuracy, providing users with a new, efficient and comfortable use experience.
