Technical Field
[0001] The mechanical keyboard of the present utility model relates to the technical field, and particularly relates to a mechanical keyboard that is convenient for assembly. Background Art
[0002] A mechanical keyboard is generally formed by snap-fitting a bottom cover, a middle plate equipped with a number of mechanical shafts, a back plate, and an upper cover. Therefore, when the mechanical shafts are pluggable shafts, at least four sets of plastic films need to be opened for the production of the mechanical keyboard, which are respectively used for producing the bottom cover, the middle plate, the back plate, and the upper cover. Or a 1+1 cavity structure is adopted to simultaneously produce an upper cover and a middle plate in a set of plastic molds. The mold structure is complex, which is likely to affect the production efficiency and the yield rate, and the production cost of plastic parts is relatively high. On the other hand, in the assembly process, it is necessary to arrange personnel to manually snap the upper cover onto the middle plate, or install an independent feeding mechanism + assembly mechanism on the assembly equipment to snap the upper cover and the middle plate, which increases the labor cost or the assembly process on the assembly equipment, and increases the failure shutdown rate of the assembly equipment, directly affecting the production efficiency. Content of the Utility Model

[0018] For ease of understanding, Figure 1 FIG. shows a schematic structural diagram of the current conventional keyboard upper cover and the middle plate. The two are independent individuals and are made of metal or plastic materials. They need to be independently formed during production. During assembly, the middle plate needs to be sleeved on the key assembly that has not been assembled with keycaps and is fixed on the bottom cover first, and then the upper cover is buckled on. The assembly process is relatively cumbersome, and the production cost and assembly cost of the keyboard components are both relatively high. To reduce costs, the present utility model makes the following improvements.
[0019] As Figures 2-4As shown in the figure, this embodiment discloses a mechanical keyboard that is convenient for assembly, including a bottom cover 20, a back plate 30, a key component 40, and a composite upper cover 10.
[0020] As Figures 2-3 shown, the composite upper cover 10 is an integrally formed structure, including an outer frame 1 with a frame structure and an inner frame 2 provided inside it. A number of hole slots 3 adapted to the keys on the keyboard are provided on the inner frame 2. To ensure a stable connection between the composite upper cover 10 and the bottom cover 20 and the back plate 30, a number of snap - fitting positioning parts 4 are provided on the outer wall of the rear wall of the outer frame 1 and the inner wall of the front wall of the outer frame 1. In addition, to prevent the inner frame 2 from deforming and ensure the shape and position accuracy of each hole slot 3, the bottom end of the inner frame 2 faces the bottom cover 20 and a number of key positioning parts 5 are provided on it. Each key positioning part 5 is provided beside one or more hole slots 3 or between a number of hole slots 3. In this embodiment, each key positioning part 5 is a hole column, with a simple structure, which is not only convenient for positioning with other structural parts, but also can be used as a reinforcing rib to strengthen the strength of the inner frame 2 and prevent the inner frame 2 from deforming or breaking. A number of first positioning parts 6 adapted to the snap - fitting positioning parts 4 are respectively provided on the bottom cover 20 and the back plate 30, a number of second positioning parts 7 adapted to the key positioning parts 5 one by one are provided on the key component 40, and a number of plug - in key shafts 43 that can be adapted to the hole slots 3 one by one are provided on the key component 40.
[0021] It can be understood that there are two fixing methods for the key shafts of commonly used mechanical keyboards at present. One is welding fixation, and the other is plug - in fixation. When using plug - in key shafts, that is, plug - in key shafts, there is no need to weld with the middle plate during assembly. Using a composite upper cover with an integrated upper cover and middle plate can not only meet the normal use of the keys, but also simplify the assembly process, reduce the number of components of the keyboard, and can reduce the production of a pair of plastic molds or simplify the mold structure, reducing the production cost and assembly cost of the keyboard.
[0022] In this embodiment, the key component 40 includes a circuit board 41, a mounting plate 42, a number of plug - in key shafts 43, and a number of keycaps 44. The circuit board 41 is mounted on the inner wall of the bottom cover 20, the mounting plate 42 is mounted on the circuit board 41 and a number of second positioning parts 7 are provided on it. Each plug - in key shaft 43 is slidably mounted on the mounting plate 42 through a support. Its lower end passes through the mounting plate 42 and extends above the circuit board 41, and its upper end passes through a hole slot 3 and extends above the inner frame 2. A keycap 44 is detachably fixed to the upper end of each plug - in key shaft 43.
[0023] During assembly, first embed the key component 40 without the keycap 43 into the inner cover 2 of the composite upper cover 10, so that the end of each key shaft 43 passes through a hole slot 3. After completion, fix the circuit board at the bottom end of the key component 40 on the bottom cover 20, and finally assemble the back plate 30 and each keycap 44.
[0024] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
