Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to an electric vehicle sliding column connecting bracket. Background Technology

[0002] With urban traffic congestion, high oil prices, and exhaust pollution, small electric vehicles are becoming increasingly popular. Traditional car front suspensions take up a lot of space, which is not conducive to their installation in small electric vehicles. The structure of the sliding strut assembly, which is connected to the steering knuckle through a connecting bracket, is conducive to miniaturization design, thereby achieving a compact structure that is easy to arrange and install.

[0003] For example, patent CN207711740U discloses a sliding column aluminum alloy lower mounting bracket structure, which includes a cylindrical body with an outer peripheral wall and an inner peripheral wall. The inner peripheral wall of the cylindrical body defines a central hole for cooperating with the cylinder of a shock absorber. A gap is provided on the cylindrical body that penetrates the outer peripheral wall and the inner peripheral wall of the cylindrical body. The gap extends from the upper surface to the lower surface of the cylindrical body. First and second clamping arms with bolt mounting holes are provided on the outer peripheral walls on both sides of the gap. The cost is relatively high and the structural stability needs to be improved. Utility Model Content

[0011] A bottom sealing plate is welded to the bottom of the outward-turning flat plate structure to seal the bottom end of the connecting sleeve. The bottom sealing plate is welded to the lower surface of the outward-turning flat plate structure.

[0012] The bottom sealing plate has an avoidance notch at the opening of the corresponding opening sleeve.

[0013] The inner sealing connecting plate has a groove on its body that matches the raised rib on the outer edge of the sliding column.

[0014] Compared with the prior art, this utility model has the following advantages: The electric vehicle sliding column connecting frame has a reasonable structural design. The connecting sleeve is an open sleeve, and the opening is folded to form a connecting support plate. The opening of the open sleeve is provided with an inner sealing connecting plate.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0020] like Figures 1 to 5 As shown, the electric vehicle slide column connecting frame 2 includes a connecting sleeve 201 for connecting to the lower end of the slide column assembly 1. A connecting support plate for connecting to the steering knuckle 3 is provided on one side of the connecting sleeve. A connecting hole is provided on the connecting support plate. The connecting arm of the steering knuckle is hinged to the connecting hole on the connecting support plate by a pin.

[0021] The connecting sleeve 201 is a side-opening sleeve, with the opening folded over to form a connecting support plate. An inner sealing connecting plate 202 is provided at the opening of the sleeve. The folded portion of the inner sealing connecting plate fits snugly against the connecting support plate to form a connection part that connects to the steering knuckle. Corresponding connecting holes are provided on the folded portions of the connecting support plate and the inner sealing connecting plate. The folded portion of the inner sealing connecting plate is welded to the connecting support plate to form a stable and reliable connection structure.

[0022] The edges of the connecting support plate have a wavy arc structure. Furthermore, the inner sealing connecting plate includes a main body and a pair of folded portions located on both sides of the main body. The folded portions are inner plates, which are welded to the connecting support plate in a shape that is consistent with the main body, effectively improving the structural strength. By strengthening the structure through its own structural form, the cost is relatively low.

[0023] The outer edge of the connecting sleeve is provided with side bracket I203 and side bracket II204. The two side brackets are bent structures and are used to fix the hose and wheel speed sensor respectively. The side bracket includes a connecting plate and a fixing plate. The connecting plate and the fixing plate are formed by stamping. The connecting plate is an arc plate that fits the outer edge of the connecting sleeve and is welded to the outer edge of the connecting sleeve.

[0024] The upper edge of the connecting sleeve is provided with an outward-turned flange structure, and the bottom end of the connecting sleeve is provided with an outward-turned flat plate structure. The structural strength is improved through the corresponding flange structures.

[0025] A bottom sealing plate 205 is welded to the bottom of the outward-turning plate structure to seal the bottom end of the connecting sleeve. The bottom sealing plate is welded to the lower surface of the outward-turning plate structure to improve the structural strength and fix the lower end of the sliding column assembly. Furthermore, the bottom sealing plate is provided with fixing holes that connect to the lower end of the sliding column assembly.

[0026] The bottom sealing plate has a clearance notch at the opening of the corresponding opening sleeve, which will not interfere with the connecting arm of the steering knuckle, and the structure is stable and reliable.

[0027] The inner sealing connecting plate has a groove on its body that matches the raised rib on the outer edge of the sliding column, which facilitates the assembly and welding of various parts to form an assembly. The lower end of the sliding column assembly is inserted into the connecting sleeve, and the inner sealing connecting plate is placed into the opening of the connecting sleeve. Positioning is achieved by the groove on the inner sealing connecting plate matching the raised rib. The folded inner plate of the inner sealing connecting plate is aligned with the connecting support plate and welded together. Then the sliding column assembly is welded together with the connecting sleeve.

[0028] This utility model electric vehicle sliding column connecting frame has a reasonable structural design. The connecting sleeve is an open sleeve, and the opening is folded to form a connecting support plate. The opening of the open sleeve is provided with an inner sealing connecting plate. The folded part of the inner sealing connecting plate fits with the connecting support plate to form a connection. The structure is stable and reliable, and the cost is low.

[0029] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.
