[0029] The following description provides specific application scenarios and requirements of this specification, with the purpose of enabling those skilled in the art to make and use the contents of this specification. Various local modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but to the widest scope consistent with the claims.

[0030] In the description of the present application, it should be noted that, unless otherwise expressly specified and limited, the terms "longitudinal", "transverse", "radial", "length", "width", "thickness", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. These terms are mainly for better describing the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0031] Secondly, the terms "first", "second" and similar words do not indicate any order, quantity or importance, but are only used to distinguish different components and should not be understood as limitations on the embodiments of the present application.

[0032] In addition, the terms "installed", "set", "provided with", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements or components.

[0033] For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] Regarding the drawings of the present application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0035] Traditional sliding switches usually rely on guide grooves to control their movement trajectory. During use, the guide grooves are prone to wear, which will cause the switch to operate unsmoothly. Secondly, the pre-load reset mechanism usually uses rubber or springs. The springs feel stiff during use, lack delicate feedback, and are easily touched by mistake, affecting the safety and operational accuracy of the equipment. At the same time, rubber materials are prone to feel degradation after long-term use, and their durability is relatively low, resulting in unclear feedback during switch operation, affecting the user's operating experience.

[0036] In order to solve the above problems, Figures 1 to 10 As shown, the present specification provides a long-life, low-friction smooth sliding switch, including a sliding member 1 and a fixed member 2, wherein the sliding member 1 is slidingly arranged relative to the fixed member 2, a sliding magnet 3 is arranged on the sliding member 1, and a fixed magnet 4 is arranged on the fixed member 2, wherein the sliding magnet 3 and the fixed magnet 4 are permanent magnets, preferably neodymium iron boron magnets, and in particular, the magnets have no complex structure and can be used directly as finished products without customization.

[0037] In this specification, by setting the relative position and magnetic pole orientation of the sliding magnet 3 and the fixed magnet 4, the sliding magnet 3 is subjected to the attractive force and repulsive force of the fixed magnet 4, the attractive force causes the sliding member 1 to achieve pre-tightening and reset movement, and the repulsive force causes a movement gap between the sliding member 1 and the fixed member 2. Specifically, the two magnetic poles of the sliding magnet 3 are arranged horizontally along the moving direction of the sliding member 1, and the two magnetic poles of the fixed magnet 4 are arranged vertically. Fig. 9 , which is the setting state of the sliding magnet 3 and the fixed magnet 4 in the present sliding switch.

[0038] With this arrangement, the function and feel are achieved through the attraction of magnets, and the performance is stable and reliable. In particular, it can provide clear and perceptible operation feedback and a smoother feel. It also avoids the problem of feel degradation of traditional rubber or springs after long-term use.

[0039] In some embodiments, the length of the sliding magnet 3 in the horizontal direction is greater than the length of the fixed magnet 4 in the horizontal direction. It can be understood that the sliding magnet 3 and the fixed magnet 4 are rectangular permanent magnets of the same specification, and their setting positions and magnetic pole orientations are referenced to Fig. 9 Such arrangement provides many beneficial effects. First, the longer lateral length of the sliding magnet 3 can provide a wider magnetic induction area. When the sliding magnet 3 moves above or near the fixed magnet 4, the area of ​​action of the magnetic field is larger, which helps to position more accurately.

[0040] Secondly, the longer sliding magnet provides a wider magnetic induction area and stronger magnetic attraction, reducing the risk of misalignment. At the same time, the longer sliding magnet 3 can maintain a larger contact area and stronger magnetic attraction during movement, which helps to improve the stability and vibration resistance of the system, especially under dynamic operating conditions.

[0041] In addition, because the sliding magnet 3 is longer, the change of the magnetic force will be smoother, so that during the sliding process of the sliding member 1, the operating feel will be more uniform and comfortable, reducing the discomfort caused by sudden changes.

[0042] In addition, it can compensate for manufacturing errors and ensure the reliability of the overall system performance.

[0043] like Fig. 9 As shown, when the sliding magnet 3 moves along the F direction following the sliding member 1 , the fixed magnet 4 generates an attractive force F1 and a repulsive force F2 on the sliding magnet 3 .

[0044] like Fig.10As shown, after magnetic simulation analysis, the sliding magnet 3 and the fixed magnet 4 adopt the setting method of the present application, and the magnetic force change curves of the two are smoother, especially when the switch is turned off, there will be no broken line magnetic lines, therefore, the sliding switch has a better feel.

[0045] In some embodiments, the number of the sliding magnets 3 is the same as the number of the fixed magnets 4, which can achieve a better magnetic force balance and uniform magnetic force change, so that the operator can feel a consistent operating feel during the switch sliding process.

[0046] In some embodiments, there are at least two sliding magnets 3 and fixed magnets 4, and adjacent sliding magnets 3 are magnetically connected in sequence, and adjacent fixed magnets 4 are magnetically connected in sequence. Fig. 9 As shown, for example, there are two sliding magnets 3 and two fixed magnets 4. Such an arrangement and reasonable arrangement of multiple magnets can adapt to switches of more specifications, as well as the hysteresis phenomenon, so that a stable and reliable magnetic field is formed, so that the attraction and repulsion of the sliding magnet 3 by the fixed magnet 4 are more stable.

[0047] In some embodiments, a first mounting groove 5 is provided on the sliding member 1, a second mounting groove 6 is provided on the fixing member 2, the sliding magnet 3 is embedded or bonded in the first mounting groove 5, and the fixing magnet 4 is embedded or bonded in the second mounting groove 6. It should be understood that other connection structures such as snap-on, bolt connection or one-piece injection molding are also possible, but the use of embedding and bonding not only ensures the connection strength but also facilitates future maintenance and replacement of parts.

[0048] In some embodiments, a sliding structure is provided between the sliding member 1 and the fixed member 2, and the sliding structure includes an optical axis 7 and a ball 8 provided along the sliding direction of the sliding member 1. The sliding member 1 and the fixed member 2 realize rolling contact with the optical axis 7 through the ball 8. Compared with the traditional guide groove structure, the relative movement between the optical axis 7 and the ball 8 is realized, the contact surface is small, the friction is low, and the service life of the switch can be greatly increased. Secondly, a buffer zone is formed by magnetic elements that repel each other but are not completely attached together, so that there is no contact and friction between the fixed blocks of the magnetic elements, and the friction force generated is only the friction between the optical axis and the roller, which further increases the service life of the switch and reduces the operating noise.

[0049] In some embodiments, the balls 8 are disposed on the upper and lower sides of both ends of the optical axis 7 . For example, the balls 8 are grouped in pairs, and at least one group is disposed at each end of the optical axis 7 .

[0050] In some embodiments, the balls 8 are staggered up and down along the axial direction of the optical axis 7 .

[0051] In some embodiments, openings 200 are provided on both sides of the fixing member 2, mounting arms 100 are provided on both sides of the sliding member 1, the mounting arms 100 are slidably provided in the openings 200, and a track plate 9 is provided on the mounting arms 100. A specific connection structure is: the track plate 9 is fixed to the mounting arms 100 by means of a screw, and the optical axis 7 is provided on the track plate 9 along the sliding direction of the sliding member 1. The optical axis 7 and the sliding member 1 can be integrated, such as integrally injection molded, or can be separately connected. The balls 8 are provided on both sides of the opening 200 of the fixing member 2 and on the upper and lower sides corresponding to both ends of the optical axis 7. For example, the fixing member 2 is in an I-shape. Such a configuration can make the entire switch structure compact, which is conducive to the miniaturization of the product.

[0052] Secondly, if Figure 5 As shown, the fixing member 2 is provided with a groove 201 adapted to the ball 8 , and fixing arms 202 are provided on both sides of the groove 201 . The two fixing arms 202 limit the ball 8 in the groove 201 , and the ball 8 can roll in the groove 201 .

[0053] In some embodiments, it also includes a shell 10 and an operating member 11, wherein the shell 10 fixing member 2 is arranged in the shell 10, and the operating member 11 is connected to the sliding member 1. It should be understood that the two can be integrated or connected separately. Generally, it is preferred to be connected separately to facilitate the installation of the sliding magnet 3. A raised operating end is provided on the operating member 11. The operating member 11 and the shell 10 are combined to form a switch housing, and the sliding member 1 and the fixing member 1 are arranged in the switch housing.

[0054] In some embodiments, a trigger end is provided on the sliding member 1, and the trigger end moves with the sliding member 1. The trigger end can cooperate with a micro switch, etc. When the operating member 11 moves, it will drive the sliding member 1 to move, and at the same time, the micro switch is triggered by the trigger end to realize the switching function.
