[0052] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0053] The technical solutions in the present application will be described below with reference to the drawings. Embodiments

[0054] A shaft body with adjustable pressing force and force coefficient, referring to Figure 1 and Figure 2 , comprising a shell 1, a button 2 slidingly arranged on the shell 1, and at least one reset component 3 for driving the button 2 to reset. The shell 1 comprises a base 11 and an upper cover 12 which is adapted to the base 11, and the upper cover 12 is located on one side of the base 11. In the present embodiment, a PCB board 8 is connected to the base 11, and the PCB board 8 faces away from the upper cover 12. In addition, the sliding direction of the button 2 is the direction in which the base 11 and the upper cover 12 face each other.

[0055] Referring to Figure 2 and Figure 3The button 2 has two ends: one end is a sliding shaft end 21, and the other end is a pressing end 22. The sliding shaft end 21 is in the shape of a long, round rod and extends along the sliding direction of the button 2. The base 11 has a long slot 5 on the side facing the upper cover 12. The long slot 5 extends along the sliding direction of the button 2. The sliding shaft end 21 and the long slot 5 are adapted to each other and slide in conjunction with each other along the length of the long slot 5. The upper cover 12 is provided with a limiting chute 6, which is also distributed along the sliding direction of the button 2 and passes through the upper cover 12. The limiting chute 6 is connected to the long slot 5, and the pressing end 22 and the limiting chute 6 are adapted to each other, so that the pressing end 22 and the limiting chute 6 slide and cooperate along the length direction of the limiting chute 6, and the limiting chute 6 limits the sliding distance of the pressing end 22, that is, when the pressing end 22 slides in the limiting chute 6, the pressing end 22 extends into or partially extends out of the upper cover 12. When the button 2 is driven to slide, the sliding shaft end 21 slides along the length direction of the long slot 5, and the pressing end 22 slides along the length direction of the limiting chute 6, thereby making the sliding process more stable and causing the pressing end 22 to extend into or partially extend out of the upper cover 12.

[0056] Reference Figure 2 and Figure 3 The base 11 further defines a mounting groove 7 on the side facing the upper cover 12. The mounting groove 7 is arranged along the sliding direction of the button 2 and is connected to the limiting slide 6. In this embodiment, the reset component 3 is a spring. There is only one reset component 3, which is also arranged along the sliding direction of the button 2. One end of the reset component 3 abuts the pressing end 22, while the other end of the reset component 3 is located within the mounting groove 7 and connected to the bottom of the mounting groove 7. The sliding shaft end 21 and the long slot 5 are both located within the reset component 3. Therefore, when the button 2 is driven to slide, the sliding shaft end 21 slides along the length of the long slot 5, and the pressing end 22 slides along the length of the limiting slide 6. The pressing end 22 compresses the reset component 3. When the button 2 is released, the reset component 3 releases its elastic force, thereby resetting the button 2. The use of a spring for the reset component 3 has the characteristics of a simple structure and easy installation.

[0057] In addition, refer to Figure 3 The housing 1 is further provided with an adjustment component 4 for adjusting the pressing force and the force coefficient, and the adjustment component 4 is provided with at least one group. Specifically, the adjustment component 4 is provided with one group, and the adjustment component 4 includes a first magnetic member 41 and a second magnetic member 42.

[0058] Reference Figure 2 and Figure 3The first magnetic member 41 is in the shape of a cylinder, and is arranged along the sliding direction of the button 2. The first magnetic member 41 extends into and is connected to the sliding shaft end 21. The first magnetic member 41 is a permanent magnet, which can provide long-term effective magnetic field strength, and the magnetic stability of the permanent magnet is not easily affected by external factors such as current and temperature changes. The second magnetic member 42 is an electromagnet, that is, the second magnetic member 42 adjusts the magnetic force and the direction of the magnetic force through the input current. The second magnetic member 42 is arranged in the mounting groove 7, and is located on one side of the reset component 3. The pin of the second magnetic member 42 is electrically connected to the PCB 8 through the base 11, so that the input current of the second magnetic member 42 can be conveniently adjusted through the PCB 8. The first magnetic member 41 and the second magnetic member 42 are arranged in a mutually attractive or repulsive manner, and the force between the first magnetic member 41 and the second magnetic member 42 can provide a component force in the sliding direction of the button 2. When the button 2 is driven to slide in the sliding direction, the first magnetic member 41 moves away from or approaches the second magnetic member 42.

[0059] Therefore, by extending the first magnetic member 41 into and connecting to the sliding shaft end 21, and fixing the second magnetic member 42 to the mounting groove 7, the collision and wear of the first magnetic member 41 during the sliding process of the button 2 are prevented, and the stability of the long-term use of the first magnetic member 41 is ensured.

[0060] When in a natural state, the pressing force and the force coefficient during the pressing process of the button 2 are affected by the force of the reset component 3, the first magnetic member 41 and the second magnetic member 42 in the sliding direction of the button 2. Based on the limiting effect of the reset component 3 and the limiting sliding groove 6, the position of the first magnetic member 41 in the natural state is ensured. By adjusting the input current of the second magnetic member 42 through the PCB 8, the magnetic force and the direction of the magnetic force of the second magnetic member 42 can be adjusted, so that the force between the first magnetic member 41 and the second magnetic member 42 is adjusted, and the component force in the sliding direction of the button 2 is further adjusted, thereby adjusting the pressing force and the force coefficient during the pressing process of the button 2. Embodiment

This arrangement makes the force between the first magnetic member 41 and the second magnetic member 42 more explicit and concentrated, which is conducive to reducing the electrical loss of the second magnetic member 42. Embodiment

[0063] The difference between this embodiment and embodiment one is that the position of the second magnetic member 42 is different.

The second magnetic member 42 is directly electrically connected with the PCB 8, and the current of the second magnetic member 42 is adjusted through the PCB 8, so that the second magnetic member 42 does not need to pass through the base 11, which is beneficial to simplify the installation of the second magnetic member 42. Embodiment

[0065] The difference between this embodiment and the first embodiment is that the position of the second magnetic member 42 is different.

Embodiment

[0067] The difference between this embodiment and the first embodiment is that the position of the second magnetic member 42 is different.

[0068] Referring to Figure 7 and Figure 8 , in this embodiment, the button 2 includes three ends, the first end of the button 2 is the sliding shaft end 21, the second end is the pressing end 22, and the third end is the linkage end 23. Among them, the sliding shaft end 21 and the pressing end 22 of the button 2 are consistent with the first embodiment, and are not repeated. The first magnetic member 41 is a permanent magnet, and the first magnetic member 41 is in the form of a ring. The first magnetic member 41 is sleeved on the sliding shaft end 21 and close to the pressing end 22. The upper cover 12 is provided with a communication groove 9, the communication groove 9 is communicated with the limiting sliding groove 6 and the mounting groove 7, and the linkage end 23 is slidably connected with the communication groove 9 along the sliding direction of the button 2.

The fourth magnetic member 32 is an electromagnet, that is, the fourth magnetic member 32 adjusts the magnetic force and the direction of the magnetic force through input current, the fourth magnetic member 32 is arranged in the mounting groove 7, the pin of the fourth magnetic member 32 is electrically connected to the PCB 8 through the base 11, and the input current of the fourth magnetic member 32 can be conveniently adjusted through the PCB 8. The third magnetic member 31 is a permanent magnet, the third magnetic member 31 and the fourth magnetic member 32 are arranged along the sliding direction of the button 2, and the third magnetic member 31 and the fourth magnetic member 32 are arranged in repulsion, so that repulsion is formed between the third magnetic member 31 and the fourth magnetic member 32, and when the button 2 is driven to slide along the sliding direction, the third magnetic member 31 is close to or away from the fourth magnetic member 32.

[0070] Therefore, when the button 2 is pressed, the button 2 slides along the shell 1, the third magnetic member 31 is driven to be close to the fourth magnetic member 32, and when the button 2 is released, the button 2 can be reset through the repulsion force formed between the third magnetic member 31 and the fourth magnetic member 32, so that the third magnetic member 31 and the fourth magnetic member 32 are adopted to prevent fatigue and performance degradation of the spring caused by long-term use, thereby prolonging the service life of the shaft body.

[0071] The second magnetic member 42 is located in the long groove 5, so that the first magnetic member 41 and the second magnetic member 42 are arranged along the sliding direction of the button 2.

[0072] When in a natural state, the pressing force and the force coefficient in the pressing process of the button 2 are affected by the force of the reset component 3, the first magnetic member 41 and the second magnetic member 42 along the sliding direction of the button 2. The current input to the second magnetic member 42 and the fourth magnetic member 32 is adjusted through the PCB 8, so that the magnetic force and the direction of the magnetic force of the second magnetic member 42 and the fourth magnetic member 32 are adjusted, thereby the component force along the sliding direction of the button 2 is adjusted, and the pressing force and the force coefficient in the pressing process of the button 2 are adjusted.
