Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please see Figures 1 to 10This utility model provides a screen field force driven inductive retractable electric device, including an upper shell 1 and a lower shell 2. A fixing plate 3 is provided at the bottom inner part of the lower shell 2. A drive shaft 4 is rotatably mounted on the middle of the fixing plate 3. A track disk 5 is provided above the drive shaft 4. Two fixed track grooves 6 are symmetrically arranged on the upper end surface of the track disk 5, and two lifting track grooves 7 are symmetrically arranged on the lower end surface of the track disk 5. The drive shaft 4 is driven by a motor 8. A fixing seat 9 is provided above the fixing plate 3, and the track disk 5 is located within the fixing seat 9. A first claw 10 and a second claw 11 are symmetrically slidably arranged between the track disk 5 and the fixing seat 9. A charging head is provided on the second claw 11. Both 11 extend to both ends of the lower housing 2. One end of the first claw 10 and one end of the second claw 11 are provided with a fixed sliding shaft 12, and the fixed sliding shaft 12 extends into the corresponding fixed track groove 6. Two sliders 13 are symmetrically slidably arranged in the fixed plate 3. Each slider 13 is provided with a lifting sliding shaft 14, and the lifting sliding shaft 14 extends into the corresponding lifting track groove 7. A first telescopic rod 15 is hinged in each slider 13. A second telescopic rod 16 is hinged on the first telescopic rod 15. A third telescopic rod 17 is hinged on the second telescopic rod 16. The upper housing 1 is hinged to the corresponding third telescopic rod 17 and is located on the two third telescopic rods 17, and is also located in the lower housing 2.

[0027] In this embodiment, by combining the cooperation of the upper housing 1, the lower housing 2, the drive shaft 4, the track disk 5, the first claw 10, and the second claw 11, the screen's magnetic induction automatic adsorption, fixation, charging, and extension functions are realized. This innovative design effectively solves the problem of complex layout in the central control area caused by too many rear electronic control physical buttons. At the same time, it provides a detachable screen system, allowing users to flexibly adjust and maintain it according to their personal needs, significantly improving the convenience and sense of ceremony of operation, and reducing the usage cost and time cost when the screen fails or is upgraded.

[0028] Furthermore, the upper end face of the upper housing 1 is provided with a magnet 19 adapted to the magnetic suction end 18 on the back of the screen. There are multiple magnets 19, and the multiple magnets 19 are arranged in a distributed manner.

[0029] In this embodiment, the distributed arrangement of the magnets 19 ensures a stable adsorption between the screen and the upper housing 1. At the same time, the magnets 19 are asymmetrical, which avoids the problem of charging interface mismatch caused by the screen being placed backwards. This design enhances the reliability of screen fixation and prevents device damage that may be caused by misoperation, thereby improving the overall safety and convenience of use.

[0030] Furthermore, a magnetic sensor 20 is provided on the upper end face of the upper housing 1, and the magnetic sensor 20 is located among the plurality of magnets 19.

[0031] In this embodiment, the magnetic sensor 20 can accurately sense the placement state of the screen and automatically trigger the motor 8 to move when the screen is correctly placed, thereby achieving automatic screen fixation and charging. The magnetic sensor acts as the "nerve endings" and "decision-making brain" of the force-driven sensing system. Through high-precision magnetic field sensing, it converts force, position, and velocity information from the physical world into digital signals, driving the electromagnetic actuator to move precisely. Simultaneously, closed-loop feedback and fault diagnosis mechanisms ensure reliable system operation. In scenarios such as automotive central control screens, wireless charging, and magnetic levitation bearings, the performance of the magnetic sensor directly determines the response speed, control accuracy, and user experience of the force-driven system, becoming a crucial bridge connecting the "physical world of force" and the "digital control world."

[0032] Furthermore, one of the fixed trajectory grooves 6 is groove A 21 and groove B 22, and the other fixed trajectory groove 6 is groove C 23 and groove D 24. Groove A 21 and groove C 23 are grooves where the first claw 10 and the second claw 11 retract, and groove B 22 and groove D 24 are grooves where the first claw 10 and the second claw 11 unfold.

[0033] In this embodiment, the fixed trajectory groove 6 achieves synchronous retraction and expansion of the first claw 10 and the second claw 11 by precisely dividing the groove segments. The A segment groove 21 and the C segment groove 23 are responsible for the retraction of the claws, which facilitates the removal of the screen; the B segment groove 22 and the D segment groove 24 are responsible for the expansion of the claws, which ensures the screen is firmly fixed. This design makes the placement and removal of the screen smoother and more reliable.

[0034] Furthermore, one of the lifting trajectory grooves 7 is E-segment groove 25 and F-segment groove 26, and the other lifting trajectory groove 7 is G-segment groove 27 and H-segment groove 28. The E-segment groove 25 and the H-segment groove 28 are the groove segments for the retraction of the upper shell 1, and the F-segment groove 26 and the G-segment groove 27 are the groove segments for the lifting of the upper shell 1.

[0035] In this embodiment, the lifting trajectory groove 7 drives the retraction of the upper housing 1 through the E-segment groove 25 and the H-segment groove 28, and drives the lifting of the upper housing 1 through the F-segment groove 26 and the G-segment groove 27, thereby realizing the flexible switching of the screen between the protection state and the use state. This design not only protects the screen from external damage, but also improves the user experience in different usage scenarios.

[0036] Furthermore, both ends of the fixing plate 3 are provided with fixing blocks 29, and the first claw 10 and the second claw 11 respectively abut against the corresponding fixing blocks 29.

[0037] In this embodiment, the fixing block 29 provides stable support and limit for the first claw 10 and the second claw 11, ensuring the accuracy and stability of the claws during movement.

[0038] Furthermore, multiple positioning rods 30 are provided at both ends of the lower housing 2, and multiple positioning sleeves 31 are provided at the other end of the first claw 10 and the other end of the second claw 11, and the multiple positioning rods 30 are located inside the corresponding positioning sleeves 31.

[0039] In this embodiment, the positioning rod 30 and the positioning sleeve 31 work together to provide precise guidance and positioning for the first claw 10 and the second claw 11.

[0040] In this embodiment, it should be noted that, in the initial state, the fixed sliding shafts 12 of the first claw 10 and the second claw 11 are respectively located in the B-segment groove 22 and the D-segment groove 24 of the track disk 5, and the lifting sliding shafts 14 of the two sliders 13 are respectively located in the F-segment groove 26 and the G-segment groove 27 of the track disk 5. At this time, the first claw 10 and the second claw 11 are in the unfolded state and the upper housing 1 is in the lifted state. When the screen with the magnetic suction end 18 is brought close to the upper housing 1, multiple magnets 19 distributed at the bottom of the upper housing 1 attract the magnetic suction end 18 on the back of the screen. At the same time, the magnetic sensor 20 located between the magnets 19 detects the change in magnetic field and triggers the motor 8 to start. The motor 8 drives the track disk 5 to rotate through the drive shaft 4. When the fixed sliding shafts 12 of the first claw 10 and the second claw 11 are respectively located in the B-segment groove 22 and the D-segment groove 24 of the track disk 5, the screen is rotated. Within slots A and C; the lifting shafts 14 of the two sliders 13 are respectively located within slots B and D of the track disk 5. At this time, the first claw 10 and the second claw 11 retract inward and fix the screen and the charging head plugged into the charging port of the screen. Simultaneously, the two sliders 13 are linked with the first telescopic rod 15, the second telescopic rod 16 and the third telescopic rod 17 respectively, controlling the upper housing 1 to descend into the lower housing 2 for protection. When the screen needs to be removed, the user triggers the screen button, the motor 8 rotates the track disk 5 in the opposite direction, the first claw 10 and the second claw 11 unfold, and the two sliders 13 are linked with the first telescopic rod 15, the second telescopic rod 16 and the third telescopic rod 17 respectively to lift the upper housing 1, allowing the user to easily remove the screen. The entire process achieves non-destructive and rapid installation and removal of the screen through the precise cooperation of magnetic induction and mechanical structure.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
