TECHNICAL FIELD
[0001] The application relates to the technical field of keyboards, in particular to a buffer structure for co-vibration of a boat shell keyboard. BACKGROUND
[0002] In today's competitive and diversified keyboard market pattern, the boat shell structure mechanical keyboard stands out and occupies a place. It is concerned because of its many outstanding characteristics. Compared with the traditional keyboard architecture, its overall layout is more regular and simple, without too many complicated splicing and gaps. This not only makes the keyboard visually give people a delicate and small impression, but also shows great convenience in actual carrying and storage process, which can easily adapt to various use scenarios, whether on a small office table or packed into a backpack for outdoor use, it will not occupy too much space.
[0003] However, most of the existing boat shell keyboards adopt the design method that the positioning plate is in direct contact with the boat (bottom) shell, and the two are in a hard connection state. When the user strikes the keyboard key, the up and down movement of the key shaft body produces an impact force. Since the positioning plate is directly and rigidly connected with the boat shell, the impact force is transmitted between the two without any buffering. On the one hand, this will cause the keyboard to produce obvious co-vibration tremor when in use, especially in a quiet environment. This noise not only interferes with the user's own concentration, but also may affect the people around. CONTENT OF THE UTILITY MODEL
[0004] In order to solve the above problems, the application provides a buffer structure for co-vibration of a boat shell keyboard.
[0005] The buffer structure for co-vibration of the boat shell keyboard provided by the application adopts the following technical scheme:

[0007] The buffer silica gel sleeve is used to reduce the co-vibration tremor generated when the metal hard positioning plate and the connecting column of the metal boat shell are in contact.
[0008] By the above technical scheme, the buffer silica gel sleeve fundamentally changes the transmission mode of vibration, so that the high-frequency, harsh and co-vibration tremor sound originally generated by the hard collision between the metal hard positioning plate and the metal hull is greatly inhibited. When using the keyboard in a quiet environment such as an office or a library, the sound produced by tapping the keyboard becomes soft and low, which does not interfere with the user's own concentration and does not cause noise disturbance to the surrounding people, thereby improving the applicability of the use scene.

[0010] Further, the metal hard positioning plate and the metal hull are connected through a screw.
[0011] Further, the inner wall thickness of the buffer silica gel sleeve decreases from bottom to top.
[0012] By the above technical scheme, the lower thicker inner wall of the buffer silica gel sleeve can form a tighter and more stable fit with the connecting column after being installed in place, because the thicker silica gel layer provides more elastic deformation space, and when being extruded by the connecting column, it can generate greater holding force, so as to ensure that the buffer silica gel sleeve will not be loosened or displaced due to slight vibration or external force impact in daily use.
[0013] Further, the top end of the buffer silica gel sleeve is provided with a cavity, and a plurality of cylinders are fixedly connected to the bottom of the cavity, and a buffer cavity is formed in the inside of each cylinder.
[0014] Further, a connecting rod is slidingly connected to the inside of each cylinder, and a first magnet is fixedly connected to the bottom of each connecting rod.
[0015] Further, a second magnet is arranged in each cylinder, and each first magnet is slidingly connected to the corresponding buffer cavity.
[0016] Further, each first magnet is located above the corresponding second magnet.
[0017] Further, each first magnet repels the corresponding second magnet.
[0018] By the above technical scheme, the magnetic force buffer and the silica gel elastic buffer are combined to form a multi-stage and multi-level buffer system, which can cope with a wider range of impact forces compared to a single silica gel buffer structure. Whether it is a soft key operation or a high-strength impact generated by a hard keyboard, it can be effectively buffered, greatly reducing the generation of co-vibration tremor sound, and creating a quiet use environment for users.
[0019] Further, the number of cylinders is at least six.
[0020] In summary, the present application includes at least one of the following beneficial technical effects:
[0021] (1) The utility model discloses a buffer silica gel cover is set up, fundamentally change the transmission mode of vibration, make the high frequency, irritating common vibration tremor that will produce between metal hard positioning board and metal ship shell because of hard collision originally get the great inhibition. When using the keyboard in the quiet environment such as office, library, the sound produced by knocking the keyboard becomes soft, low, does not disturb the concentration of user itself, also does not cause the noise trouble to the surrounding personnel, greatly improves the applicability of use scene.
[0022] (2) The utility model discloses a magnetic force buffer and silica gel elastic buffer are combined, form a multi-stage, multi-level buffer system. Compared with single silica gel buffer structure, this design can cope with more extensive range of impact force, whether it is soft key operation or the high-strength impact produced by the heavy knock of keyboard, can be effectively buffered, greatly reduces the generation of common vibration tremor, creates a quiet use environment for the user.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application;Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments;Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0030] Embodiment one
[0031] Reference Figures 1-2 A buffer structure for the co-vibration of a ship shell keyboard, comprising a metal hard positioning plate 1, a metal ship shell 4 arranged below the metal hard positioning plate 1, the metal hard positioning plate 1 being arranged on the inner side of the metal ship shell 4, a buffer silica gel sleeve 3 arranged between the metal hard positioning plate 1 and the metal ship shell 4, and a connecting column arranged on the top of the metal ship shell 4, the buffer silica gel sleeve 3 being sleeved on the outer wall of the connecting column.
[0032] The buffer silica gel sleeve 3 is used to reduce the co-vibration sound generated when the metal hard positioning plate 1 and the connecting column of the metal ship shell 4 are in contact.
[0033] When a user strikes a key of the ship shell keyboard, the key shaft body drives the metal hard positioning plate 1 to move up and down. Since the metal hard positioning plate 1 and the metal ship shell 4 are no longer in direct hard contact but are connected through the buffer silica gel sleeve 3, the impact force transmitted by the metal hard positioning plate 1 first acts on the buffer silica gel sleeve 3. The buffer silica gel sleeve 3 will be elastically deformed under the action of the impact force due to its high elasticity and good flexibility. This deformation process can effectively absorb and disperse the energy transmitted by the metal hard positioning plate 1, avoiding the direct transmission of energy to the connecting column of the metal ship shell 4 in the form of rigid collision. When the impact force is processed by the buffer silica gel sleeve 3 and then transmitted to the metal ship shell 4, its strength has been greatly weakened, thereby blocking the strong vibration conduction path caused by hard contact and greatly reducing the source of co-vibration sound.
[0034] Through the arrangement of the buffer silica gel sleeve 3, the transmission mode of the vibration is fundamentally changed, so that the high-frequency and harsh co-vibration sound originally generated between the metal hard positioning plate 1 and the metal ship shell 4 due to hard collision is greatly inhibited. When using the keyboard in a quiet environment such as an office or a library, the sound produced by striking the keyboard becomes soft and low, which does not interfere with the user's own concentration and does not cause noise disturbance to the surrounding people, thereby improving the applicability of the use scene.
[0035] Reference Figures 1-2 The metal hard positioning plate 1 is internally provided with a threaded hole 2, the connecting column of the metal ship shell 4 is internally provided with a mounting hole, and the metal hard positioning plate 1 and the metal ship shell 4 are connected through screws.
[0036] Reference Figures 1-3 The thickness of the inner wall of the buffer silica gel sleeve 3 decreases from bottom to top.
[0037] The thicker inner wall of the lower part of the buffer silica gel sleeve 3 can form a tighter and more stable fit with the connecting column after being installed in place, because the thicker silica gel layer provides more elastic deformation space, and when subjected to extrusion by the connecting column, it can generate greater holding force, ensuring that the buffer silica gel sleeve 3 will not loosen or shift during daily use due to slight vibrations or external force impacts.
[0038] Embodiment two
[0039] Referring to Figure 3 Figure 5 The top end of the buffer silica gel sleeve 3 is provided with a cavity 7, and the bottom of the cavity 7 is fixedly connected with a plurality of cylinders 5. The interiors of the plurality of cylinders 5 are each provided with a buffer cavity 10. The interiors of each of the cylinders 5 are slidably connected with a connecting rod 6. The bottom of each of the connecting rods 6 is fixedly connected with a first magnet 8. Each of the cylinders 5 is provided with a second magnet 9. Each of the first magnets 8 is slidably connected with a corresponding buffer cavity 10. Each of the first magnets 8 is located above a corresponding second magnet 9. Each of the first magnets 8 repels the corresponding second magnet 9. The number of the cylinders 5 is at least six.
[0040] When the key is struck, the metal hard positioning plate 1 moves downward to generate an impact force and transmits it to the buffer silica gel sleeve 3. At this time, the structure located in the top end cavity 7 begins to play a role. Since each of the cylinders 5 is provided with repelling first and second magnets 8 and 9, and the first magnet 8 is fixedly connected with the connecting rod 6 and can slide in the buffer cavity 10, when the impact force is transmitted to the cavity 7 area, in the initial stage, the impact force causes the connecting rod 6 to drive the first magnet 8 to move downward. Due to the magnetic force of the same polarity repelling each other, when the first magnet 8 approaches the second magnet 9, it will be subjected to a strong repulsive force. This repulsive force will resist the downward trend of the first magnet 8, which is equivalent to providing a reverse buffer force for the impact force, slowing down the speed of the impact force acting on the bottom of the buffer silica gel sleeve 3 and the metal hull 4, and converting part of the energy into magnetic potential energy for temporary storage. As the impact force continues, the first magnet 8 continues to move downward under the dual action of overcoming the magnetic force and its own gravity, compressing the air in the buffer cavity 10. The compressed air, like a spring, generates a spring force opposite to the direction of the impact force, further assisting the buffer silica gel sleeve 3 to disperse and absorb energy.
[0041] Through the combination of magnetic force buffering and the elastic buffering of silica gel itself, a multi-stage and multi-level buffering system is formed. Compared with the single silica gel buffering structure of embodiment one, this design can cope with a wider range of impact forces, whether it is a soft key operation or a high-intensity impact generated by a hard strike on the keyboard, which can be effectively buffered, reducing the generation of common tremor sound and creating a quiet use environment for users.
[0042] Working principle: when the user hits the hull keyboard key action occurs, due to the metal hard positioning plate 1 below the close set with buffer silica gel sleeve 3, and the buffer silica gel sleeve 3 is located outside the metal hull 4 connecting column, metal hard positioning plate 1 transmission of the impact force first on the buffer silica gel sleeve 3. With the unique high elasticity and flexibility of silica gel material, buffer silica gel sleeve 3 responds quickly, begin to occur elastic deformation, this deformation process can effectively absorb and disperse the energy from the metal hard positioning plate 1, avoid the energy directly with rigid collision way to the connecting column of the metal hull 4. When the impact force after the buffer processing of buffer silica gel sleeve 3, and then transmitted to the metal hull 4, its strength has been greatly weakened, thus breaking the strong vibration caused by the strong vibration transmission path, greatly reducing the generation of the root cause of the common tremor.
[0043] The above are the preferred embodiments of the present application, not limited by the protection scope of the present application, therefore: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
