However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0024] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 The shown structure is an intelligent knob structure that moves on a car screen, including a central control screen 1, a knob switch 2, a lower slide rail 3 and an upper slide rail 4 fixed to the central control screen 1. The upper slide rail 4 and the lower slide rail 3 are arranged up and down. A sliding seat 5 is provided at the bottom of the knob switch 2, and the sliding seat 5 is slidably connected to the lower slide rail 3. The knob switch 2 includes a knob body 6 and a PCB board 7. A display screen 20 is provided on the top of the knob body 6. A bayonet 8 is provided on the side of the knob body 6 facing the upper slide rail 4. The upper slide rail 4 slides in cooperation with the bayonet 8. The bayonet 8 has a blocking surface 9 and a guide inclined surface 10 connected to the blocking surface 9 and inclined downward. The upper slide rail 4 enters the bayonet 8 from the side and the side wall and bottom wall of the upper slide rail 4 are respectively fitted with the blocking surface 9 and the guide inclined surface 10.

[0026] Slide the knob body 6 onto the lower slide rail 3, align the bayonet 8 of the knob body 6 with the upper slide rail 4 from the side and insert it. The blocking surface 9 and the guide slope 10 in the bayonet 8 fit with the side and bottom surfaces of the upper slide rail 4 respectively. The installation accuracy requirement is low and the positioning installation can be achieved quickly.

[0027] A layer of damping pad 11 is fixed to the inner wall of the bayonet 8. The damping pad 11 includes two damping surfaces connected as one and respectively fitted with the blocking surface 9 and the guide slope 10. The damping pad 11 is arranged in the bayonet 8. The damping pad 11 is preferably made of rubber. When the knob body 6 slides, a damping force is generated to prevent the knob body 6 from being accidentally moved. At least a certain thrust is required from the finger.

[0028] A support frame 12 for installing the knob body 6 is provided on the top of the sliding seat 5. The knob body 6 is connected to the support frame 12 by snapping, plugging or screwing. It is designed according to actual conditions. The PCB board 7 is connected to the side wall of the support frame 12, and the knob body 6 is connected to the top of the support frame 12. The lower sliding rail 3 includes two connecting plates 13 and guide bars 14 fixed between the two connecting plates 13 and arranged at intervals. The knob body 6 and the sliding seat 5 are located at the upper and lower ends of the guide bar 14. The upper surface of the sliding seat 5 is provided with a slide groove 15 that slides with the guide bar 14. A movable distance is left between the lower end of the knob body 6 and the guide bar 14.

[0029] Specific method: Since there is a distance between the knob body 6 and the sliding seat 5, the sliding seat 5 on which the knob body 6 is installed is installed into the lower rail 3 from the side. The sliding seat 5 is located below the guide bar 14. After the slide groove 15 is aligned with the guide bar 14, the sliding seat 5 is pushed upward to make the two fit together. The knob body 6 is installed into the upper slide rail 4 from the side, and finally the lower rail 3 is fixed. The knob body 6 can be limited between the upper slide rail 4 and the lower slide rail 3, and the positioning installation can be quickly achieved.

[0030] A support ear 16 is provided on one side of the two connections close to each other. The support ear 16 is perpendicular to the connecting plate 13 and a through hole 17 is provided on the support ear 16 .

[0031] A slot 18 is provided on the side of the upper slide rail 4 corresponding to the central control screen 1. The slot 18 is pre-buried with multiple magnets 19 arranged in the NS direction along the length direction. The PCB board 7 is parallel to the magnet 19 and a Hall sensor is provided on the PCB board 7.

[0032] When the knob switch 2 reaches different positions, it switches to the corresponding function synchronously, that is, the same knob switch 2 is used in different operating positions to realize the function of the corresponding position to control different components. The display screen 20 will also switch to the corresponding value, such as volume, wind speed, temperature, etc. The volume adjustment, wind speed adjustment, temperature adjustment and other functions can be realized by opening the components, and when different functions are realized in different positions, the knob switch 2 will generate different gears and damping forces to avoid misoperation. By pre-embedding multiple magnets 19 and Hall sensors in the upper slide rail 4, the final phase difference pulse signal is used to determine the moving distance or left and right position of the knob relative to the central control screen 1. This is an existing technology, and no specific explanation is given on how to realize the switching.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
