Description

A waterproof keyboard and its installation method

technical field

The invention belongs to the technical field of keyboards, in particular to a waterproof keyboard and an installation method thereof.

Background technique

The keyboard is the most commonly used and also the most important input device for the computer. The English letters, numbers, punctuation marks, etc. are input into the computer through the keyboard, so as to input data and issue instructions to the computer.

See the patent No. CN202021210567 for details, and the technical solution is (exclusive item): see Figure 1-Figure 15, including keyboard lower case 1, circuit board 2, waterproof membrane 3, pressure frame 4, keycap sliding part 5, keyboard Panel 6 and key cap 7, wherein, there is circuit board 2 inside the keyboard lower case 1, and there is a waterproof membrane 3 above the circuit board 2, and the pressure frame 4 is arranged on the top of the waterproof membrane 3, and is fixed to the keyboard lower case 1 by screws The key cap sliding part 5 is embedded in the upper end of the keyboard lower case 1; the keyboard panel 6 is fastened on the top of the key cap sliding part 5, and fixed with the keyboard lower case 1 by screws; Buckled on the keycap sliding fitting part 5.

The problem solved by the comparative technical solution: water entering into the keyboard will cause the circuit board of the keyboard to short circuit and burn out.

The commercially available desktop keyboard of prior art has two kinds, and a kind of is to be commonly called as " crater keyboard ", and another kind is " mechanical keyboard ".

The existing commercially available "crater keyboard" belongs to the middle and low-end keyboard: due to the high cost of PCB board 2-4 (circuit board 2 adopts PCB circuit board), it is abandoned by "crater keyboard". The circuit board 2 of the "keyboard" all adopts a flexible circuit sheet 2-1; the flexible circuit sheet 2-1 is composed of three layers of films, and the silver paste is printed on the two films respectively to form two 'circuit films', and then the three layers The films are bonded together, wherein the isolation film is located between two 'circuit films', and the silver paste switch contacts on the two 'circuit films' correspond to the isolation round holes on the isolation film. When a switch is triggered , the upper film is elastically deformed, and a 'silver paste contact' on the upper layer enters the isolation hole to contact and conducts with a 'silver paste contact' on the lower layer. When the external force is removed, the upper film resets, and the two 'silver paste contacts' Separation; the biggest advantage of the flexible circuit sheet 2-1 is its ultra-thin thickness and low cost.

The existing commercially available "mechanical keyboards" are high-end keyboards: the "mechanical keyboard" circuit boards 2 all use PCB boards 2-4 with a thickness of about 2mm. Taking the "mechanical keyboard" with 104 keys as an example, the PCB boards 2-4 There are 104 independent 'mechanical switches' welded on it, and a keycap is connected to each mechanical switch. It is obvious that the existing "mechanical keyboard" is not suitable for installing a waterproof membrane 3 .

An in-depth analysis of three detailed comparative technical options that can be implemented:

Referring to Fig. 1, the keyboard panel 6 is fixedly connected with the keycap sliding part 5, wherein the keycap sliding part 5 is located in the space inside the keyboard panel 6, the keycap 7 is slidably fitted with the keycap sliding part 5, and the pressing frame 4 The waterproof membrane 3 is tightly pressed on the lower keyboard case 1 by screws, the keyboard panel 6 is fixedly connected to the lower keyboard case 1 by screws, and the circuit board 2 is located in the space inside the lower keyboard case 1 .

Referring to Fig. 2-Fig. 9, the keyboard lower case 1 is provided with a ring-shaped cover 1-2, a casing connection hole 1-3, a pressure frame hole 1-4, a pressure frame connection column 1-5, and a ring-shaped vertical edge 1-9, Wherein, the annular cover 1-2 is a plane, and the inner side of the annular cover 1-2 is a downwardly concave sealing space (concave The space can accommodate the circuit board 2), the outer side of the annular cover 1-2 is connected to the annular vertical edge 1-9, and the lower surface of the annular cover 1-2 is provided with a pressure frame connecting column 1- 5. The pressure frame hole 1-4 runs through the upper surface of the ring cover 1-2. It should be ensured that the pressure frame hole 1-4 is located in the pressure frame connecting column 1-5 and is concentric with it. The inner side of 1-2 is set; the keyboard panel 6 is provided with a panel connection boss 6-1 and a panel connection hole 6-3, wherein the panel connection hole 6-3 is located in the panel connection boss 6-1 and is concentric with it.

Refer to Fig. 5, Fig. 7, Fig. 9, Fig. 13. Compared with the technical solutions, the connection holes 1-3 of the shell must be located outside the pressure frame 4 (that is, the connection holes 1-3 of the shell are located outside the pressure frame holes 1-4); the keyboard A plurality of cylindrical panel connecting bosses 6-1 are arranged around the edge of the panel 6, and the screws penetrate through the shell connecting holes 1-3 on the lower surface of the keyboard lower case 1 and connect with the panel on the panel connecting boss 6-1. The connecting hole 6-3 is fixedly connected, and the panel connecting boss 6-1 is located outside the pressure frame 4.

The waterproof membrane 3 is made of rubber, and a plurality of elastic Dome3-1 are arranged on the plane of the waterproof membrane 3. Under the action of elastic force, the Dome3-1 pushes the keycap 7 to the upper limit position; in order to improve the rigidity of the pressure frame 4 , to ensure that the waterproof membrane 3 is reliably sealed. The connection between the pressure frame 4 and the keyboard lower case 1 uses small M2 self-tapping screws. The diameter of the pressure frame holes 1-4 on the pressure frame 4 is 2.2mm, and the width of the pressure frame 4 is 6mm. , the left and right width of the pressure frame 4 near the pressure frame holes 1-4 is 1.9mm, and the height of the pressure frame 4 is 1.8mm. The increase in the size of the pressure frame 4 can improve the rigidity of the pressure frame 4 and reduce the M2 self-tapping screw. Quantity, but this will increase the length and width of the keyboard, and the height of the pressing frame 4 is limited by the space in the keyboard.

Referring to Fig. 5, Fig. 7, Fig. 9, and Fig. 14, the dimension L from the keycap of the keyboard to the four edges of the keyboard panel 6 is 7.5mm (the outer diameter of the connecting column 1-5 of the pressing frame) + 7.5mm (the panel connecting Outer diameter of boss 6-1)+6mm (width of press frame 4)+0.5mm (gap between press frame 4 and panel connecting boss 6-1)+0.8mm (panel connects boss 6-1 and Gap between ring-shaped vertical sides 1-9)+2.5mm (the wall thickness of ring-shaped vertical sides 1-9)=24.8mm; Compared with existing commercially available keyboards, the setting scheme of independent pressure frame 4 makes key The dimension L from the cap to the edge of the keyboard panel 6 has more than doubled. The existing commercially available keyboards generally use 2mm self-tapping screws to connect the plastic keyboard panel 6 and the plastic keyboard lower shell 1. In order to ensure reliable connection, the frame connecting column 1- 5. The outer diameter of the panel and the boss 6-1 are all >7.5mm. Detailed comparison of technical solution a: see Figure 3 and Figure 5. The existing keyboard and keyboard lower shells 1 are all produced by injection molding. There is a downwardly concave sealed space; the bottom of the sealed space is provided with a large plane 1-1 of the lower case, and the circuit board 2 adopts a flexible circuit sheet 2-1, and the flexible circuit sheet 2-1 is connected with the large plane 1-1 of the lower case, and connected The method is adhesive connection or screw connection, but the adhesive connection is considered to be the best; since the concave lower case large plane 1-1 is set on the inner side of the sealing surface 1-5 of the keyboard lower case 1, the keyboard lower case is in a shell shape The thickness of 1 is very thin, compared with the technical solution a keyboard lower case 1 has extremely poor rigidity and is not practical.

Detailed comparison of technical solution b: see Fig. 6-Fig. 7, the circuit chip support 1-6 is arranged on the keyboard lower case 1, the number of the circuit chip support 1-6 is the same as the number of the keycap, and the upper end surface of the circuit chip support 1-6 One-to-one correspondence with the elastic Dome3-1 and the 'silver paste contacts' on the flexible circuit sheet 2-1, wherein the upper end faces of the many circuit sheet pillars 1-6 are located on the same plane, and the flexible circuit sheet 2-1 is It is fixedly connected to the upper end surfaces of many circuit chip pillars 1-6, and the rest are the same as technical scheme a; comparing Fig. 5 and Fig. 7 to show It is easy to see that the rigidity of the lower keyboard case 1 of the technical solution b is better than that of the lower keyboard case 1 of the technical solution a, but the rigidity of the lower keyboard case 1 of the technical solution b is still not fast, and is still not practical.

Detailed comparison technical scheme c: see Fig. 8-Fig. 9, arrange vertically and horizontally arranged circuit chip support ribs 1-7, circuit chip connection platform 1-8, the upper end surface of circuit chip support ribs 1-7, circuit The upper end surfaces of the sheet connection table 1-8 are all on the same plane. When installing, the flexible circuit sheet 2-1 is stacked on the upper surface of the steel plate, and the flexible circuit sheet 2-1 and the steel plate and the circuit sheet connection table 1- 8. Fixed connection, so that the flexible circuit sheet 2-1 and the steel plate are connected with the keyboard lower case 1 to form a rigid whole. This scheme has the best rigidity, but due to the large length and width of the keyboard, its rigidity is poor, and the injection molding material shrinks after cooling. , and the injection molding precision of large-sized shell-shaped parts is low. From the perspective of purchasing the keyboard, even if the steel plate is added, at least three screw holes need to be set near the middle of the keyboard along the length direction. 1 is fixedly connected with the keyboard panel 6, and the three screws need to pass through the waterproof membrane 3, and the three openings of the waterproof membrane 3 will definitely destroy the waterproof effect of the waterproof membrane 3, and the rest are the same as technical solution a.

See Fig. 10-Fig. 13. The installation process of the comparison technical solution is: first place the circuit board 2 in the sealed space of the keyboard lower case 1, and fix the circuit board 2 in the keyboard lower case, and then screw the pressure frame 4 It is fixed with the keyboard lower case 1, so that the pressure frame 4 can press-seal the waterproof membrane 3 on the keyboard lower case 1; in summary, with this technical solution, it is impossible for the circuit board 2 to be connected with the keycap sliding part 5 or the keyboard panel 6, It can only be fixedly connected with the keyboard lower case.

Referring to Fig. 14-Fig. 17, the technical solution of the present invention is compared with the keyboard shape view of the comparative technical solution, wherein Fig. 14-Fig. The front 3D diagram and the reverse 3D diagram of the keyboard of the technical solution of the present invention.

Problems in comparing technical solutions:

1. Compared with technical solutions, the cost of the keyboard increases

(1) The length and width of the keyboard have increased by about 12mm (conventional keyboard) --- 19mm (compact keyboard)

The material cost of the upper and lower key shells of the keyboard is increased and the cost of the injection mold for producing the upper and lower key shells is increased due to the increase of the mold;

(2) The comparative technical scheme adopts the independent press frame 4 parts, and adopts the screws for fixing the press frame 4;

Increased the processing technology cost and installation process cost of the independent press frame 4 parts;

Increase the material cost of the screw, especially increase the screw installation process cost;

(3) In order to ensure reliable sealing of the waterproof membrane, due to the low rigidity of the pressure frame 4, reliable sealing must be achieved by increasing the number of screws;

Increase the material cost of 28 screws, especially increase the installation process cost of 28 screws;

(4), the keycap sliding part 5 and the keyboard panel 6 are designed as two independent parts, which increases the process cost;

2. Compared with technical solutions, the appearance of the keyboard is very ugly, and the appearance structure is complicated, which increases the difficulty of cleaning the keyboard (not practical)

(1) The dimension L from the keyboard keycap to the edge of the keyboard panel 6 is greatly increased, and the distance is increased by about 6mm (the width of the pressure frame 4 is 6mm), The dimension L has been increased by about 1 times, and the appearance of the keyboard is out of proportion, see Figure 14-Figure 17;

(2) A large number of ring-shaped pressure frame connecting columns 1-5 are added to the lower surface of the keyboard lower case 1, resulting in a complex appearance structure of the keyboard lower case 1 and increasing the difficulty of cleaning the keyboard (see Figures 14-17);

3. Comparing the technical solutions - the consistency of the keyboard feel and the poor sensitivity of the keyboard

Since the lower shells of the keyboard are processed by injection molding, the lower shells of the keyboard are shell-shaped (the wall thickness is about 2.5mm). At the same time, the size of the lower shell of the keyboard is relatively large (taking a 104-key keyboard as an example, its length and width are about 440mm*140mm ), after the injection molding process is completed, the deformation of the lower shell of the keyboard is relatively large and the injection molding precision is low; The distance H (see Figure 5) of the lower end surface of the cap sliding part 5 is inconsistent, so that the feel of the keycaps at both ends of the keyboard in the length direction is obviously inconsistent with the feel of the keycaps in the middle of the keyboard; the prior art solution (commercially available keyboard) is further To solve the problem of inconsistent hand feel, when the upper keyboard panel is connected to the lower keyboard shell 1 (thin film circuit sheet 2-1 lower lining steel plate), generally 16 screws need to be installed, of which about 12 screws are arranged around the keyboard, and around the middle of the keyboard along the length Arrange about 4 screws in the direction; generally, about 23 screws need to be installed when the keyboard lower case is connected with the upper keyboard panel (when no steel plate is installed), of which about 12 screws are arranged around the keyboard, and about 11 screws are arranged around the keyboard ; Because the size of the keyboard panel 6 and the keyboard lower case 1 is relatively large, after the keyboard is installed, the deformation of the keyboard lower case 1 causes the distance H between the keycap 7 and the middle part of the keyboard lower case 1 and the keycap 7 to the keyboard lower case 1. The size error is large, causing the keycap 7 in the middle of the keyboard to feel inconsistent with the keycap 7 on the edge of the keyboard; the keyboard of the commercially available prior art solution generally uses a rigid plate (steel plate) to connect with the keyboard lower case 1 to increase the keyboard lower case 1 The rigidity is near the middle of the keyboard lower case 1, and several screws are used to fix the keyboard panel 6 and the keyboard lower case 1;

4. The waterproof effect is poor (compared with the technical solution, the keyboard can only achieve limited waterproofing)

a. Compared with technical solutions, due to the limitation of the size of the keyboard and the structure of the keyboard, the size of the pressure frame 4 is poor, and the rigidity of the pressure frame 4 is poor, and the effect of compressing and sealing the surroundings of the waterproof membrane 3 through the pressure frame 4 is relatively poor;

b. Comparing the technical scheme with no keyboard indicator light waterproof technical scheme;

c. Comparing technical solutions with waterproof technical solutions without ubs line (electrical connection 8) or ps2 line (electrical connection 8);

d. In order not to damage the waterproof effect of the waterproof membrane 3, the keyboard of the comparative technical solution can only be realized: the connection between the keyboard panel 6 and the keyboard lower case 1 is only connected by screws around the keyboard, and in the inner range of the frame 4, the keyboard panel 6 and the keyboard lower case 1 are connected by screws. The keyboard lower shell 1 has no connection, therefore, it is very necessary to invent a keyboard with low cost, good hand feeling and better water resistance (can be soaked in water for cleaning).
