[0002] The existing patent for Hall element magnetic shaft keyboard key switch, patent number 2024223061297, discloses a Hall element magnetic shaft keyboard key switch. Specifically, it discloses that the keyboard key switch function is achieved by moving the magnet and adjusting the distance between the magnet and the Hall element. However, vertically, the Hall element is not directly below the magnet. When the magnet is moved downward by the pressing device, the shaking affects the voltage, which in turn affects the stability of the key switch. Summary of the Invention

[0003] In view of the shortcomings in the prior art, the present invention provides a novel Hall element magnetic shaft keyboard key switch, and overcomes the above-mentioned defects.

[0004] The technical solution adopted by this invention to solve its technical problem is: a novel Hall element magnetic shaft keyboard key switch, including a top cover, a pressing device, a base, and an electronic assembly. The electronic assembly includes a connecting terminal, an auxiliary block, a circuit board, and a Hall element disposed on the circuit board. One end of the connecting terminal is connected to the auxiliary block, and the other end passes through the circuit board and the base in sequence. The pressing device forms a guide with the top cover, and pressing realizes relative longitudinal movement. The magnet is fixed on the pressing device, the auxiliary block has a clearance notch, the Hall element corresponds to the notch, and the magnet is located above the Hall element.

[0005] The connecting terminal includes a body and a connecting auxiliary part. The connecting auxiliary part has barbs and a connecting end extending downward from the connecting auxiliary part. The connecting end is parallel to the body. The auxiliary block has a fixing groove for accommodating the connecting auxiliary part and the body. The body and the connecting auxiliary part are integrally formed.

[0006] The auxiliary block is provided with a fixing groove, and the circuit board is provided with through holes and connection holes for the main body and the connection end to pass through.

[0007] The pressing device includes a pressing body, a pressing part, a guide strip and a magnet receiving block disposed on the side wall of the pressing body, and an elastic element (not shown in the figure) is provided between the pressing device and the base.

[0008] The upper cover is provided with a through hole, and the side wall of the through hole is provided with a guide groove corresponding to the guide bar.

[0009] The inner wall of the guide groove and the inner wall of the through hole are provided with ribs, and the guide ribs are provided with grooves.

[0010] The guide groove extends toward the base.

[0011] The magnet receiving block is provided with a receiving groove for receiving magnets, and the side wall of the receiving groove is provided with ribs.

[0012] A manufacturing process for a novel Hall element magnetic shaft keyboard key switch includes the following steps: Step 1: First, fix the connecting terminals on the auxiliary block, and at the same time, apply solder paste to points 1, 2, 3, 4, 5, and 6 on the circuit board; Step 2: Place the Hall element at positions 1, 2, and 3 on the circuit board with solder paste applied using the nozzle, and secure it firmly. Step 3: Insert the connecting terminals from Step 1 into the holes or slots on the circuit board, and then use high temperature to cure them with solder paste to achieve electrical connection between the connecting terminals and the circuit board. Step 4: Install the completed electronic assembly into the base; specifically, the connecting terminals pass through the bottom of the base. Step 5: At the same time, connect the pressing device to the top cover. The pressing device is inserted into the top cover from below, with the guide strip corresponding to the guide groove and the pressing body passing through the through hole. Step 6: The top cover and the base are snapped together, with an elastic element between the pressing device and the base.

[0013] By adopting the above technical solution, the problem of existing magnetic axis keyboard key switches where the Hall element is placed on the side of the magnet, causing it to wobble during the up-and-down movement of the magnet and thus affecting the stability of the key switch, is effectively improved. By placing the magnet above the Hall element, the stability of the key switch is enhanced. Attached Figure Description

[0023] refer to Figure 1-9 As can be seen, the present invention discloses a novel Hall element magnetic shaft keyboard key switch, including an upper cover 1, a pressing device 2, a base 3, and an electronic assembly 4. The electronic assembly 4 includes a connecting terminal 5, an auxiliary block 6, a circuit board 7, and a Hall element 73 disposed on the circuit board 7. One end of the connecting terminal 5 is connected to the auxiliary block 6, and the other end passes through the circuit board 7 and the base 3 in sequence. The pressing device 2 forms a guide with the upper cover 1, and pressing realizes relative longitudinal movement. The pressing device 2 is provided with a magnet 8, the auxiliary block 6 is provided with a clearance notch 61, the Hall element 73 corresponds to the notch 61, and the magnet 8 is located above the Hall element 73.

[0024] The connecting terminal 5 includes a body 51 and a connecting auxiliary part 52. The connecting auxiliary part 52 is provided with barbs 521 and a connecting end 522 extending downward from the connecting auxiliary part 52. The connecting end 522 is parallel to the body 51. The auxiliary block 6 is provided with a fixing groove 62 for accommodating the connecting auxiliary part 52 and the body 51.

[0025] The auxiliary block 6 is provided with a fixing groove 62, and the circuit board 7 is provided with a through hole 71 and a connection hole 72 for the main body 51 and the connecting end 522 to pass through, as shown in the attached figure. Figure 7 As shown, solder paste is applied to the connection hole 72 to complete the electrical connection between the circuit board 7 and the connection terminal 5. The auxiliary block 6 is used to firmly fix the connection terminal 5, because the thickness of the bottom of the base 3 and the thickness of the circuit board 7 alone cannot ensure the installation firmness of the connection terminal 5.

[0026] The main body 51 and the connecting auxiliary part 52 are integrally formed, as shown in the attached figure. Figure 9 As shown.

[0027] The pressing device 2 includes a pressing body 21, a pressing part 22, a guide strip 23 disposed on the side wall of the pressing body 21, and a magnet receiving block 24. An elastic element (not shown in the figure) is provided between the pressing device 2 and the base 3. (See attached figure) Figure 2 As shown, the top of the pressing body 21 is provided with a groove 211, the pressing part 22 is placed in the groove 211, the pressing body 21 passes through the through hole 11, and the through hole 11 is provided with a rib 9.

[0028] The upper cover 1 is provided with a through hole 11, and the side wall of the through hole 11 is provided with a guide groove 12 corresponding to the guide bar 23. The inner wall of the guide groove 12 and the inner wall of the through hole 11 are provided with ribs 9, as shown in the attached figure. Figure 3As shown, the end of the rib 9 located in the guide groove 12 facing the base 3 is set with an inclined surface 91, which facilitates the guide bar 23 to slide into the guide groove 12. The guide bar 23 is provided with a groove 231, which is combined with the attached... Figure 2 As shown, this design increases the tight fit between the guide bar 23 and the guide groove 12 while reducing friction between them. The groove 231 provides space for the guide bar 23 to deform. Preferably, most of the guide bars 23 are made of plastic.

[0029] The guide groove 12 extends toward the base 3. (See attached image) Figure 2-3 As shown, a sufficiently long forming track is provided for the guide bar 23.

[0030] The magnet receiving block 24 is provided with a receiving groove 241 for receiving the magnet 8, and the side wall of the receiving groove 241 is provided with ribs 9, as shown in the attached figure. Figure 4 As shown, the magnet 8 is placed in the receiving groove 241 by means of the reinforcing bar 9, or is fixedly connected to the receiving groove 241 by means of the magnet 8 adhesive, or is fixed in the receiving groove 241 by means of both the reinforcing bar 9 and adhesive.

[0031] A manufacturing process for a novel Hall element magnetic shaft keyboard key switch includes the following steps: Step 1: First, fix the connecting terminals on the auxiliary block, and at the same time, apply solder paste to points 1, 2, 3, 4, 5, and 6 on the circuit board; Step 2: Place the Hall element at positions 1, 2, and 3 on the circuit board with solder paste applied using the nozzle, and secure it firmly. Step 3: Insert the connecting terminals from Step 1 into the holes or slots on the circuit board, and then use high temperature to cure them with solder paste to achieve electrical connection between the connecting terminals and the circuit board. Step 4: Install the completed electronic assembly into the base; specifically, the connecting terminals pass through the bottom of the base. Step 5: At the same time, connect the pressing device to the top cover. The pressing device is inserted into the top cover from below, with the guide strip corresponding to the guide groove and the pressing body passing through the through hole. Step 6: The top cover and the base are snapped together, with an elastic element between the pressing device and the base.

[0032] Specifically, as shown in the attached document Figure 9 As shown, firstly, the connecting terminal 5 is fixedly connected to the auxiliary block 6. The end of the auxiliary part 52 is inserted into the fixing groove 62, and the barbs 521 make the connecting auxiliary part 52 and the fixing groove 62 firmly connected. Preferably, the auxiliary block is made of adhesive-free material; then, combined with the attached... Figure 7 As shown, the inserted connector 5 body 51 and connector 522 are inserted into the through hole 71 and connector 72 of the circuit board 7, respectively. The Hall element 73 corresponds to the notch 61. The connected state is shown in the attached figure. Figure 8 As shown. (Attached) Figure 8The assembled electronic assembly 4 is connected to the base 3, and then... Figure 6 As shown, the connecting terminal 5 passes through the bottom of the base 3, and finally... Figure 5 Filling as shown; combined with attachments Figure 2-4 As shown, the pressing device 2 with magnet 8 is connected to the upper cover 1, that is, the guide strip 23 cooperates with the guide groove 12. An elastic element (not shown in the figure) is provided between the pressing device 2 and the base 3. Finally, the upper cover 1 is connected to the base 3 to complete the assembly. In this application, the pressing device 2 cooperates with the upper cover 1, and the upper cover 1 is connected to the base 3. Compared with the original structure where the upper cover, base, and pressing device cooperate with each other, the installation tolerance of this application is smaller, improving the user experience. Furthermore, the Hall element 73 is a point, and the magnet 8 is a surface. The magnet 8, located directly above the Hall element 73, moves downward to reduce the impact of shaking during the pressing process on the voltage, thereby enhancing the stability of the Hall switch. By setting the auxiliary block 6, the Hall element 73 is placed near the bottom of the base 3, providing sufficient space in the small volume of the Hall element magnetic axis keyboard key switch so that the Hall element 73 and the magnet 8 are arranged vertically in an up-down structure.

[0033] This invention effectively improves upon the problem in existing magnetic shaft keyboard key switches where the Hall element 73 is placed on the side of the magnet 8, causing the magnet 8 to wobble during vertical movement and thus affecting the stability of the key switch. By positioning the magnet 8 above the Hall element, the stability of the key switch is enhanced.

[0034] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
