[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown, an intelligent digital display steering wheel includes a control panel 1. The length of the control panel 1 is greater than its width, and the overall structure is similar to a rectangle. The top and both ends of the control panel 1 are convex arc edges, with the arc at both ends being greater than that at the top. The bottom of the control panel 1 is a concave arc edge, with the arc at the bottom being greater than that at both ends. The corners are rounded, making the overall shape smooth and aesthetically pleasing.

[0026] like Figure 5 As shown, the control panel 1 has handles 103 at both ends, and vertical strip-shaped grips 4 on both sides of the handles 103. The grips 4 are positioned close to the edges of the handles 103 to increase the operator's grip comfort and facilitate gripping force. A digital control screen 7 is installed in the middle of the control panel 1, displaying information such as speed, mileage, gear position, and SOC, enabling real-time monitoring of driving status. A bottom cover 3 is installed at the bottom of the control panel 1, which is fixed to the main control panel by five hexagonal head screws. Figure 3 As shown, the bottom cover 3 houses the main control board 10, which is fixed to the control panel 1. The bottom of the display screen is located inside the bottom cover 3.
