DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1-3 , the utility model provides a technical solution: an intelligent locking device for a car steering wheel frame, comprising: a lower support frame, a column 6, and an electric telescopic rod 5;

[0025] The lower support frame is located on the lower side, and a PLC controller 4 is arranged on the lower support frame. The columns 6 are longitudinally arranged on both sides of the upper surface of the lower support frame, and the upper ends of the columns 6 are connected with support arms 12. The adjacent sides of the support arms 12 on both sides extend downward to form pressure blocks 13. The electric telescopic rod 5 is installed on both sides of the lower support frame, and the electric telescopic rod 5 on both sides is located between the columns 6 on both sides. The upper side of the telescopic end of the electric telescopic rod 5 is connected with a lower support block 8, and the lower support block 8 corresponds to the position of the pressure block 13. The upper surface of the lower support block 8 is recessed to form a steering wheel skeleton clamping groove 9, and a pressure sensor 10 is arranged on the lower side of the steering wheel skeleton clamping groove 9. The signal output end of the pressure sensor 10 is connected to the PLC controller 4, and the signal output end of the PLC controller 4 is connected to the electric telescopic rod 5.

[0026] Analysis of the above content: When in use, the telescopic end of the electric telescopic rod 5 first descends to drive the lower support block 8 to descend, and the outer ring of the steering wheel frame is placed in the steering wheel frame clamping groove 9 of the lower support block 8. Then the electric telescopic rod 5 pushes the lower support block 8 to approach the pressure block 13. At the same time, the pressure sensor 10 detects the pressure on the upper part to judge the degree of clamping and tightening of the outer ring. The pressure is set within a safe range to ensure that the outer ring is clamped and avoid damage to the outer ring. The pressure safety range value is stored in the PLC controller 4, and the pressure value detected by the pressure sensor 10 is transmitted to the PLC controller 4, and the detected pressure value is compared with the pressure safety range value. When the detected pressure value is less than the pressure safety range value, the lower support block 8 continues to push up until the detected pressure value is within the pressure safety range value.

[0027] Embodiment 2:

[0028] See also Figure 1-3 The utility model provides a technical solution based on the first embodiment: the lower support frame includes a base plate 1 and a support platform 3 connected to the upper side of the base plate 1, the columns 6 are connected to both sides of the upper surface of the support platform 3, the PLC controller 4 is arranged on the lower surface of the support platform 3, the electric telescopic rod 5 is connected to both sides of the support platform 3, and a connecting bracket 2 is arranged between the base plate 1 and the support platform 3.

[0029] Analysis of the above content: Through the combination of the base plate 1 and the support platform 3, the whole is lifted.

[0030] Embodiment three:

[0031] See also Figure 1-3 The utility model provides a technical solution based on the first embodiment: a sleeve 7 is slidably connected to the outer wall of the column 6, the sleeve 7 is fixedly connected to the side wall of the lower support block 8, the side of the sleeve 7 away from the lower support block 8 is connected to the support plate 11, the arm 12 is rotatably connected to the top of the pillar 6 through a pin, and the end of the arm 12 away from the pressing block 13 corresponds to the position of the support plate 11. The end of the arm 12 away from the pressing block 13 is rotatably connected to the support roller 14 through a pin, and the upper surface of the support plate 11 is in contact with the support roller 14. The upper end of the side wall of the column 6 is connected to an elastic support member 15, and the other end of the elastic support member 15 is connected to the end of the arm 12 close to the pressing block 13.

[0032] Analysis of the above content: When in use, the telescopic end of the electric telescopic rod 5 pushes the sliding sleeve 7, the lower support block 8, and the support plate 11 to rise. Since in this embodiment, the support arm 12 can rotate relative to the pillar 6, the support plate 11 rises and pushes the support arm 12 to rotate, so that the pressure block 13 and the lower support block 8 are close to each other, and the outer ring is clamped. In order to maintain the stability of the inner spokes, a structure for supporting the inner spokes can be set on the upper surface of the support platform 3 (not shown in the figure, because after the outer ring is stable, the inner spokes can be easily fixed and welded. When necessary, the existing support blocks or clamps matching the inner spokes can be used to support or clamp the inner spokes).
