Description

Technical Field

[0001] The invention relates to the technical field of computer equipment, in particular to a multifunctional wireless keyboard. Background Art

[0002] A keyboard is a device for inputting commands and data to operate computer equipment. It also refers to a group of function keys that are arranged by the system to operate a machine or device. It includes two different styles: wired keyboards and wireless keyboards. Among them, wireless keyboards are more convenient to use because they eliminate the wiring harness design and are quite popular among young people.

[0003] In the prior art, a Chinese patent document with a publication number of CN112363630B proposes a multifunctional computer keyboard, which can generate and store electricity by arranging a key body, a rubber elastic sleeve, a sliding plate, a first electrode, a connecting rod 1, a spring 2, a friction layer, a second electrode, a fixing, a storage battery, a fan and a nozzle. The electricity in the storage battery can be used to power the fan after long-term use. The fan can remove dust and impurities in the gaps between the keys of the keyboard body through the nozzle, thereby keeping the keyboard clean and tidy. In addition, the temperature of people's hands can be reduced when it is hot, so as to avoid the user's hands from sweating and causing poor use experience. In actual use, although this type of keyboard has many functions, it is consistent with the traditional wireless keyboard in that the main keyboard area on the keyboard is fixedly connected to the numeric keypad area. Usage experience shows that since there is an editing key area containing direction keys between the numeric keypad area and the main keyboard area, the distance between the numeric keypad area and the main keyboard area is larger. For novice users, their eyes need to switch back and forth between the main keyboard area and the numeric keypad area, and the fixed relative position will cause inconvenience in use, and eyes fatigue will occur over time. Therefore, the present application discloses a multifunctional wireless keyboard to meet the demand for convenient use of wireless keyboards. Summary of the invention

[0018] Compared with the prior art, the present invention provides a multifunctional wireless keyboard, which has the following beneficial effects:

[0019] 1. For the "veterans" who are proficient in operating the keyboard, if the keyboard needs to be used as a whole, the main keyboard and the small keyboard are connected. The detailed operation is to align the connecting piece with the connecting slot and push the connecting piece into the connecting slot. During this period, the connecting piece extending into the connecting slot has a rounded corner, so that it first contacts the hemisphere. Under the guidance of the vertical guide rod, the hemisphere is forced to move downward. When the connecting piece continues to be pushed forward, the hemisphere is under the elastic force of the vertical spring, so that the shift block moves up with the vertical guide rod and pushes the hemisphere into the corresponding limit hole, so that under the pulling force of the horizontal spring, the slider remains relatively fixed, and then the limit operation of the connecting piece is completed, which is very convenient for novice users. When using the keyboard, one is often not familiar with the specific positions of the keys on the keyboard and needs to constantly lower his head to observe. Therefore, the distance between the small keypad and the main keyboard should be as small as possible to facilitate operation. At this time, by pulling down the dial block and pulling the hemisphere out of the limit hole, the limiting effect on the limit hole and even the connecting piece is released, thereby facilitating the separation of the small keypad from the main keyboard, so that the small keypad can be moved to a position adjacent to the main keyboard, shortening the distance between the main keyboard and the small keypad, and facilitating observation and operation. In addition, the sealing ring and sealing groove are provided to improve the sealing inside the connecting piece.

[0020] 2. The multifunctional wireless keyboard, when the keyboard is used as a whole, after the main keyboard and the small keyboard are connected, the connecting piece is connected to the slider through the hemisphere, and the rotating rod is pressed to rotate downward, thereby releasing the limiting effect of the second ratchet block on the ratchet wheel, and cooperating with the elastic force of the second torsion spring, the first ratchet block has a one-way limiting effect on the ratchet wheel, so that along with the intermittent reciprocating downward rotation operation of the rotating rod by hand, the ratchet wheel is engaged by the edge of the rotating rod, and the ratchet wheel is driven to drive the rotating shaft to rotate intermittently and wind the elastic band, so that the slider is moved a distance away from the small keyboard through the traction effect of the elastic band, and then the connecting piece is driven by the slider to move in the direction close to the main keyboard, so as to improve the extrusion resistance strength between the sealing ring and the sealing groove, and can compensate for the shrinkage deformation of the rubber sealing ring after long-term and multiple uses, so as to ensure the connection sealing strength between the main keyboard and the small keyboard under normal use at all times, so as to improve the service life of the electronic components inside the keyboard and improve the practicality of the entire wireless keyboard.

For new When using the keyboard with hands, users are often not familiar with the specific positions of the keys on the keyboard and need to constantly lower their heads to observe. Therefore, the distance between the small keyboard 2 and the main keyboard 1 should be as small as possible to facilitate operation. At this time, by pulling down the dial block 11 and pulling the hemisphere 10 out of the limit hole 13, the limiting effect on the limit hole 13 and even the connecting member 3 is released, thereby facilitating the separation of the small keyboard 2 from the main keyboard 1, so that the small keyboard 2 can be moved to a position adjacent to the main keyboard 1, reducing the distance between the main keyboard 1 and the small keyboard 2, and facilitating observation and operation.

The elastic band 16 is used to pull the slider 8 away from the keypad 2, and then the slider 8 drives the connector 3 to move toward the main keyboard 1, thereby increasing the extrusion resistance between the sealing ring 5 and the sealing groove 6, and compensating for the shrinkage deformation of the rubber sealing ring 5 after long-term and multiple uses, thereby ensuring the connection sealing strength between the main keyboard 1 and the keypad 2 under normal use at all times, thereby increasing the service life of the electronic components inside the keyboard and improving the practicality of the entire wireless keyboard.
