Detailed Implementation
[0025] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.
[0028] To address the problems existing in the background technology, this application proposes the following technical solution: including a bottom shell 1, an upper shell 2 detachably mounted on the bottom shell 1, a keyboard body 3 disposed between the bottom shell 1 and the upper shell 2, a PCB board 18 fixedly connected to the bottom of the keyboard body 3, a lower contact 6 disposed on the bottom shell 1, a connecting block 7 fixedly mounted on the PCB board 18, an upper contact 8 fixedly connected to the connecting block 7, and the upper contact 8 and the lower contact 6 being adapted to each other.
[0029] The bottom shell 1 houses power supply and control modules. After the keyboard body 3 is placed on the bottom shell 1, the connecting block 7 on the PCB board 18 contacts the lower contact 6 on the bottom shell 1, electrically connecting the power supply and control modules in the bottom shell 1 to the PCB board 18 under the keyboard body 3. The keyboard body 3 is fixed between the bottom shell 1 and the top shell 2 by being detachably installed on the bottom shell 1. The contact connection replaces the traditional keyboard ribbon cable connection, allowing for instant separation when disassembling and replacing the keyboard body 3 without worrying about damage to the ribbon cable. The operation is simple and convenient, and the internal structure of the keyboard is also more concise and aesthetically pleasing, improving the user experience.
[0030] Furthermore, a positioning block 4 is fixedly installed on the bottom shell 1, and a connecting groove 5 is provided on the positioning block 4, which is compatible with the connecting block 7.
[0031] When the keyboard body 3 is placed on the bottom shell 1, the position of the connecting block 7 is aligned with the connecting groove 5 and then the connecting block 7 is inserted into the connecting groove 5, which ensures the accuracy of the contact between the lower contact 6 and the upper contact 8. At the same time, the connecting groove 5, together with the connecting block 7, plays a guiding and limiting role for the PCB board 18 and the keyboard body 3, so that the keyboard body 3 is placed stably on the bottom shell 1.
[0032] Furthermore, a magnet 9 is fixedly installed at the bottom of the connecting block 7, and the magnet 9 can be attached to the positioning block 4.
[0033] The positioning block 4 is made of ferromagnetic material. The lower contact 6 passes through the positioning block 4 and is located in the connecting groove 5 without contacting the positioning block 4. After the connecting block 7 is inserted into the connecting groove 5, the magnet 9 is attracted to the positioning block 4, which further improves the stability of the keyboard body 3 placed on the bottom shell 1. At the same time, it ensures the contact between the lower contact 6 and the upper contact 8, avoids poor contact and open circuit, and improves the stability of the keyboard during use.
[0034] To further explain, a ball-bearing head 10 is fixedly installed on the lower part of the upper shell 2, and a bottom block 12 is fixedly connected to the lower shell 1. A slot 17 is provided on the bottom block 12, and the slot 17 is adapted to the ball-bearing head 10.
[0035] When the upper shell 2 is installed on the bottom shell 1, the lower end of the ball bearing head 10 is inserted into the connecting block 7 of the bottom block 12 to position the upper shell 2 and improve the accuracy of the upper shell 2 during installation.
[0036] Furthermore, the bottom block 12 has an installation groove 13, in which an installation plate 14 is fixedly installed. A spring 15 is fixedly installed on one side of the installation plate 14, and a ball 16 is fixedly connected to one end of the spring 15.
[0037] During the insertion of the ball head 10 into the slot 17, the ball head 10 contacts and presses against the ball 16, pushing the ball 16 towards the mounting plate 14. The ball 16 compresses and deforms the spring 15, and the spring force of the spring 15 pushes the ball 16, causing the ball 16 to apply pressure to the ball head 10, thus fixing the ball head 10 in the slot 17 (as shown in the attached diagram). Figure 6 As shown in the figure, the upper shell 2 is then connected to the lower shell 1 via the ball head 10 and the bottom block 12. When the user applies a certain external force, the upper shell 2 moves the ball head 10 to remove it from the slot 17, thus separating the upper shell 2 from the lower shell 1. This allows for maintenance or replacement of the keyboard body 3, achieving a detachable connection between the lower shell 1 and the upper shell 2 without the need for tools, making it more convenient and faster.
[0038] Furthermore, the ball head 10 is provided with a positioning part 11, which is adapted to the ball 16.
[0039] After the positioning part 11 is inserted into the slot 17, the spring 15 pushes the ball 16 to the position of the slot 17. The slot 17 cooperates with the ball 16 to make the positioning part 11 more accurately and firmly connected to the bottom block 12, thereby improving the accuracy and stability of the connection between the bottom shell 1 and the upper shell 2.
[0040] For specific usage instructions, please refer to the following: When installing the keyboard body 3, place the keyboard body 3 on the bottom shell 1, align the position of the connecting block 7 with the connecting groove 5, insert the connecting block 7 into the connecting groove 5, and the magnet 9 will be attracted to the positioning block 4. The connecting block 7 on the PCB board 18 will contact the lower contact 6 on the bottom shell 1, making the power supply and control modules in the bottom shell 1 electrically connected to the PCB board 18 under the keyboard body 3. Then, place the upper shell 2 on the bottom shell 1 and press it down. The striker head 10 will be inserted into the slot 17. During this process, the striker head 10 will contact and press the ball 16, pushing the ball 16 towards the mounting plate 14. The ball 16 will compress and deform the spring 15. The elastic force of the spring 15 will push the ball 16, causing the ball 16 to apply pressure to the striker head 10, fixing the striker head 10 in the slot 17. This will cause the upper shell 2 to be snapped and fixed on the bottom shell 1. To disassemble the keyboard, the user can apply a certain amount of external force to remove the upper shell 2 and the keyboard body 3 from the bottom shell 1 in sequence.
