[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0029] The utility model provides a center-added magnet switch structure, comprising a base and a button. The base is provided with an oil storage tank with an open top and a closed bottom. The oil storage tank is arranged around the outer periphery of a guide column of the base. A slideway for the button to slide is arranged in the oil storage tank.

[0030] The utility model provides an oil storage tank with an open top and a closed bottom on the base, which makes it convenient to add lubricating oil into the base. The oil storage tank can effectively store the lubricating oil without overflowing. The lubricating oil can form an oil film on the button and the slideway, effectively reducing the sliding friction between the button and the slideway, reducing wear, ensuring that the sliding action of the button runs stably and smoothly, and improving the feel of use. The utility model is particularly suitable for axis notebook computers and computer keyboard buttons.

[0031] Furthermore, there are two slideways, which are symmetrically arranged in the oil storage tank. The height of the slideway is greater than the height of the oil storage tank to ensure that the sliding action of the button runs stably and smoothly.

[0032] As an optional embodiment, it also includes an upper cover, which is detachably buckled on the base and forms a cavity for the button to slide between the upper cover and the base.

[0033] Furthermore, first fasteners are respectively provided on two parallel side walls of the outer side wall of the base, and a second fastener engaged with the first fastener is provided on the upper cover. The upper cover and the base are fastened together by the engagement of the first fastener and the second fastener, which facilitates assembly and disassembly, and prevents foreign matter from entering the cavity, affecting use or causing damage to the button, thereby extending the service life of the button and ensuring that the switch structure can operate stably for a long time. The first fastener and the second fastener adopt the existing technology, which will not be described in detail here.

[0034] As an optional implementation, a pressing portion is provided on the upper part of the button, a positioning column is provided on the lower part of the button, a positioning groove is provided at the center of the positioning column, a magnet is embedded in the positioning groove, and the positioning column can drive the magnet to slide back and forth along the guide hole of the guide column.

[0035] In the cavity, the button passes through the top of the upper cover, and the positioning column is embedded in the guide hole and can slide back and forth along the axial direction of the guide hole. Applying external force to the pressing part of the button drives the positioning column to drive the magnet to move downward, and the magnet approaches the PCB board located under the base. The components on the PCB board can sense the magnetic field changes of the magnet, thereby making the circuit conductive.

[0036] As an optional implementation, a spring is arranged between the base and the button, a first end of the spring is sleeved with the positioning column, and a second end of the spring is sleeved with the guide column.

[0037] Furthermore, the second end of the spring is located in the oil storage tank, which effectively reduces the sliding friction between the spring and the guide column and reduces wear.

[0038] The spring can provide a reset force for the button. Applying external force to the pressing part of the button drives the positioning column to move the magnet downward, and the magnet approaches the PCB board under the base. The components on the PCB board can sense the magnetic field changes of the magnet, thereby making the circuit conductive. At this time, the spring is in a compressed state.

[0039] When the external force disappears, the reset action of the spring drives the button to automatically reset upward, so that the magnet is away from the PCB board, and the circuit is in a disconnected state.

[0040] As an optional implementation, a protrusion is provided on the inner peripheral wall of the positioning groove, and the number of the protrusions is plural and extends in an axial direction parallel to the positioning groove.

[0041] The function of the protrusion is to increase the friction between the magnet and the positioning groove, thereby ensuring the stability and reliability between the magnet and the positioning groove.

[0042] As an optional implementation, a sliding portion is provided on the outer side wall of the button, and the sliding portion is slidably matched with the slideway.

[0043] Furthermore, there are two sliding parts, which are respectively arranged on two parallel side walls of the outer side wall of the button. The sliding action of the button is realized through the sliding cooperation between the sliding part and the slideway.

[0044] As an optional implementation, the sliding portion includes a mounting groove and a silicone member. The mounting groove is arranged on the outer wall of the button and is plugged into and matched with the silicone member. A accommodating cavity for accommodating the silicone member is opened on the mounting groove, and a raised first rib is arranged on the outer wall of the mounting groove.

[0045] Furthermore, there are two mounting grooves, which are respectively arranged on two parallel side walls of the outer side wall of the button. After the silicone piece is assembled into the accommodating cavity, the silicone piece protrudes from the mounting groove. During the button resetting process, the silicone piece first contacts the structure of the upper shell, which greatly reduces the sound of the button hitting the upper cover during the button resetting process, and has a good mute effect.

[0046] The thickness of the first rib increases gradually in the direction toward the base, so that the contact area between the first rib and the slideway is small, the sliding friction is small, and the sliding action of the button is ensured to be stable and smooth.

[0047] As an optional implementation, the sliding portion includes a sliding member, the sliding member and the button are integrally formed, the outer wall surface of the sliding member is provided with a raised second rib, and the top surface of the sliding member is provided with a raised third rib.

[0048] Furthermore, the thickness of the second rib increases gradually in the direction toward the base, so that the contact area between the second rib and the slideway is small, the sliding friction is small, and the sliding action of the button is ensured to be stable and smooth.

[0049] During the button reset process, the third rib first contacts the structure of the upper shell, effectively reducing the sound caused by the button hitting the upper cover when it is reset.

[0050] Embodiment 1:

[0051] like Figure 1-5 As shown, the utility model provides a center-magnet switch structure, including a base 1 and a button 2. The base 1 is provided with an oil storage tank 11 with an open top and a closed bottom. The oil storage tank 11 is arranged around the outer periphery of a guide column 12 of the base 1. A slideway 13 for the button 2 to slide is arranged in the oil storage tank 11.

[0052] The utility model is provided with an oil storage tank 11 with an open top and a closed bottom on the base 1, so that it is convenient to add lubricating oil into the base 1. The oil storage tank 11 can effectively store the lubricating oil without overflowing. The lubricating oil can form an oil film on the button 2 and the slide 13, effectively reducing the sliding friction between the button 2 and the slide 13, reducing wear, ensuring that the sliding action of the button 2 runs stably and smoothly, and improving the feel of use. The utility model is particularly suitable for axis notebook computers and computer keyboard buttons.

[0053] Further, such as Figure 2 , 3 As shown, there are two slideways 13 symmetrically arranged in the oil storage tank 11 , and the height of the slideway 13 is greater than the height of the oil storage tank 11 to ensure that the sliding action of the button 2 is stable and smooth.

[0054] As an optional implementation, Figure 1 As shown, it also includes an upper cover 3, which is detachably buckled on the base 1 and forms a cavity between the upper cover 3 and the base 1 for the button 2 to slide.

[0055] Furthermore, first snap fasteners are respectively provided on two parallel side walls in the outer side wall of the base 1, and a second snap fastener is provided on the upper cover 3 to be snap-connected with the first snap fastener. Through the snap-fit ​​cooperation of the first snap fastener and the second snap fastener, the snap-fit ​​connection between the upper cover 3 and the base 1 is achieved, which facilitates assembly and disassembly, and prevents foreign matter from entering the cavity, affecting use or causing damage to the button 2, thereby extending the service life of the button 2 and ensuring that the switch structure can operate stably for a long time.

[0056] As an optional implementation, a pressing portion 21 is provided on the upper portion of the button 2, and a positioning column 22 is provided on the lower portion of the button 2. A positioning groove 221 is provided at the center of the positioning column 22, and a magnet 5 is embedded in the positioning groove 221. The positioning column 22 can drive the magnet 5 to slide back and forth along the guide hole 121 of the guide column 12.

[0057] In the cavity, the button 2 passes through the top of the upper cover 3, and the positioning column 22 is embedded in the guide hole 121 and can slide back and forth along the axial direction of the guide hole 121. When an external force is applied to the pressing portion 21 of the button 2, the positioning column 22 is driven to drive the magnet 5 to move downward, and the magnet 5 is close to the PCB board located below the base 1. The components on the PCB board can sense the change in the magnetic field of the magnet 5, thereby making the circuit conductive.

[0058] As an optional implementation, Figure 2 As shown, a spring 4 is arranged between the base 1 and the button 2 , a first end of the spring 4 is sleeved with the positioning column 22 , and a second end of the spring 4 is sleeved with the guide column 12 .

[0059] Furthermore, the second end of the spring 4 is located in the oil storage tank 11, which effectively reduces the sliding friction between the spring 4 and the guide column 12 and reduces wear.

[0060] The spring 4 can provide a reset force for the button 2. When an external force is applied to the pressing portion 21 of the button 2, the positioning column 22 is driven to drive the magnet 5 to move downward, and the magnet 5 is close to the PCB board located below the base 1. The components on the PCB board can sense the magnetic field changes of the magnet 5, thereby making the circuit in a conducting state. At this time, the spring 4 is in a compressed state.

[0061] When the external force disappears, the reset action of the spring 4 drives the button 2 to automatically reset upward, so that the magnet 5 is away from the PCB board, and the circuit is in a disconnected state.

[0062] As an optional implementation, Figure 4 As shown, a protrusion 222 is provided on the inner peripheral wall of the positioning groove 221 . The number of the protrusions 222 is plural and they extend in a direction parallel to the axial direction of the positioning groove 221 .

[0063] The function of the protrusion 222 is to increase the friction between the magnet 5 and the positioning groove 221 , thereby ensuring the stability and reliability between the magnet 5 and the positioning groove 221 .

[0064] As an optional implementation, a sliding portion is provided on the outer side wall of the button 2 , and the sliding portion is slidably matched with the slideway 13 .

[0065] Furthermore, there are two sliding parts, which are respectively arranged on two parallel side walls of the outer side wall of the button 2. The sliding action of the button 2 is achieved through the sliding cooperation between the sliding part and the slideway 13.

[0066] As an optional implementation, Figure 4 , 5 As shown, the sliding part includes a sliding member 6 , which is integrally formed with the button 2 , the outer wall surface of the sliding member 6 is provided with a second rib 61 with a protrusion 222 , and the top surface of the sliding member 6 is provided with a third rib 63 with a protrusion 222 .

[0067] Furthermore, the sliding member 6 is integrally formed with the button 2 by injection molding. The thickness of the second rib 61 increases gradually toward the base 1, so that the contact area between the second rib 61 and the slideway 13 is small, the sliding friction is small, and the sliding action of the button 2 is ensured to be stable and smooth.

[0068] During the reset process of the button 2 , the third rib 63 first contacts the structure of the upper shell, effectively reducing the sound caused by the button 2 hitting the upper cover 3 when being reset.

[0069] Embodiment 2:

[0070] The difference between Example 2 and Example 1 is that: Figure 6As shown, the sliding part includes a mounting groove 7 and a silicone member 8. The mounting groove 7 is arranged on the outer wall of the button 2 and is plugged into the silicone member 8. A receiving cavity for accommodating the silicone member 8 is opened on the mounting groove 7, and a first rib 71 with a protrusion 222 is arranged on the outer wall of the mounting groove 7.

[0071] Furthermore, there are two mounting grooves 7 , which are respectively arranged on two parallel side walls of the outer side wall of the button 2 .

[0072] The silicone member 8 can be arranged in an I-shaped structure, and a receiving cavity adapted to the silicone member 8 is provided on the mounting groove 7, so as to improve the stability and reliability of the connection between the silicone member 8 and the mounting groove 7. After the silicone member 8 is assembled into the receiving cavity, the silicone member 8 protrudes from the mounting groove 7. During the reset process of the button 2, the silicone member 8 first contacts the structure of the upper shell, which greatly reduces the sound generated by the button 2 hitting the upper cover 3 during the reset process, and has a good mute effect.

[0073] The thickness of the first rib 71 increases gradually in the direction toward the base 1 , so that the contact area between the first rib 71 and the slideway 13 is small, and the sliding friction is small, thereby ensuring that the sliding action of the button 2 runs stably and smoothly.
