Description

Technical Field

[0001] The invention relates to a vehicle instrument, in particular to a display instrument used for an electric vehicle. Background Art

[0002] As the functions of electric bicycles become more and more abundant, it is common to install a meter or dashboard on the handlebars of electric bicycles. The meter or dashboard is connected to the mobile phone via Bluetooth to display the electric bicycle's speed, mileage, navigation and other information. Most dashboards in the prior art are fixedly connected to the handlebars. In this way, the content displayed on the dashboard can only be presented in one format, and sometimes screen information is wasted. For example, the space occupied by information such as driving speed and mileage is very small, but other areas in the horizontal / vertical direction will be wasted; sometimes the screen information is not fully displayed, for example, the navigation display needs to show as much information about the surrounding area as possible, but this cannot be achieved because the screen is fixed. In general, the current dashboard on electric bicycles is inefficient and cannot meet the needs of various working conditions. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing technical defects and provide a display instrument for electric vehicles which has higher use efficiency and can be applied to more working conditions.

[0004] The technical solution of the present invention is to provide a display instrument for electric vehicles with the following structure: it includes an instrument panel and a base, the base includes a vertical section and an arc section that are interconnected, a square block is connected to the instrument panel, the cross-sectional shape of the square block is square, the square block slides linearly in the vertical section in the base, and the square block rotates 90° in the arc section of the base; the square block is provided with a first slide rail and a second slide rail that are perpendicular to each other and intersecting, the first slide rail and the second slide rail both extend outward from the center point of the square block as a starting point and penetrate the side wall of the square block along their own length direction, the arc section of the base is connected to a rotating shaft, and when the square block rotates 90° in the arc section of the base, the intersection section where the first slide rail and the second slide rail on the square block intersect with the rotating shaft on the arc section of the base is pressed against and rotates around the rotating shaft.

[0005] After adopting the above structure, compared with the prior art, the square block of the present invention can maintain a horizontal or vertical state in the vertical section, and after the square block slides from the vertical section into the arc section, it can complete a 90° turning action in the arc section, thereby expanding the application occasions of the instrument panel fixed on the square block: in the scenario where navigation is required, the instrument panel can maintain a horizontal state, display as much surrounding map information as possible, and highlight the terrain information; when it is necessary to display the cruising range and vehicle speed, it can maintain a vertical state and highlight the text size. In summary, the present invention provides a display instrument for electric vehicles that is more efficient and applicable to more working conditions.

[0006] As a preferred embodiment of the present invention, the vertical section, the arc section and the base form a shell structure, the vertical section opening width is equal to the length of the square block section, the vertical section length is greater than the length of the square block section, the arc section diameter is greater than the diagonal length of the square block section, and the arc section center coincides with the axis center. Through this preferred embodiment, the square block can be limited in the vertical section and can also be rotated in the arc section.

[0007] As a preferred embodiment of the present invention, the inner walls of the vertical section in three directions are provided with sliding grooves, the outer walls of the square block are provided with horizontal convex strips, and the horizontal convex strip on the outer wall of one side of the square block is located in the sliding groove on the inner wall of one side of the vertical section in contact with it. Through this preferred embodiment, a guide can be provided for the square block to slide in the vertical section to prevent the square block from escaping from the vertical section.

[0008] As an improvement of the present invention, a buckle is provided in the slide groove at the bottom of the vertical section, and two adjacent horizontal ridges among the four horizontal ridges on the outer wall of the square block are provided with through holes for cooperating with the buckle, and one of the two horizontal ridges with through holes is located on the side wall of the square block away from the first slide rail, and the other of the two horizontal ridges with through holes is located on the side wall of the square block away from the second slide rail. According to this preference, when the square block is in a horizontal / vertical state, the through hole on the square block can be engaged with the buckle on the vertical section, thereby preventing the square block from sliding randomly in the vertical section during the driving of the vehicle, that is, the buckle can play a fixing role on the square block.

[0009] As an improvement of the present invention, the first slide rail on the square block is perpendicular to the side wall of its opening, and the second slide rail on the square block is perpendicular to the side wall of its opening; the cross section of the intersection of the first slide rail and the second slide rail on the square block is an arc transition, and the diameter value of the arc transition of the intersection is equal to the diameter value of the rotating shaft on the arc section of the base. Through this optimization, the rotation of the square block around the rotating shaft can be made more stable, and the cooperation between the arc transition of the intersection and the rotating shaft can guide the rotation of the square block.

[0010] As an improvement of the present invention, the square block is connected with a support column, and the support column is fixedly connected to the instrument panel. Through this optimization, the support column can provide space for the direct layout of the instrument panel and the base.

[0011] As an improvement of the present invention, the symmetry axis of the circular arc segment on the base coincides with the symmetry axis of the vertical segment on the base. Through this optimization, the movement of the square block in the vertical segment and the circular arc segment is more stable.

[0012] As an improvement of the present invention, the first slide rail opening has rounded corners, and the second slide rail opening has rounded corners. Through this optimization, it is convenient for the rotating shaft of the arc segment to enter the first slide rail or the second slide rail when the square block enters the arc segment.
