Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, specifically to an actuator foot support plate with a bushing. Background Technology

[0002] In the field of automotive actuator footrests, these are adjustable foot support devices with integrated electric actuators, typically installed under the seat. They can be adjusted for extension or angle via a motor to accommodate different passenger needs and improve comfort. The assembly and connection between the footrest body and the bushing is a core structural element, requiring welding to ensure support stability. This directly affects the footrest's load-bearing capacity and lifespan, and this connection method is the mainstream solution in the industry.

[0003] Existing welding structures mostly employ spot welding or partial full welding designs, which have some drawbacks. For example, the welding process is prone to stress concentration, and when the footrest plate is subjected to long-term pressure from the legs of drivers and passengers, cracks or even breakage can easily occur at the weld points, affecting safety. These factors shorten the overall durability of the components and limit the performance improvement of the actuator footrest plate. Therefore, the welding structure at the assembly points of vehicle components needs further optimization. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an actuator foot plate with a bushing.

[0005] To solve the above problems, this utility model provides an actuator foot support plate with a bushing. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: An actuator foot support plate with a bushing includes: a support plate; a bushing, which sequentially includes a first shaft segment, a flange segment, and a second shaft segment along a unidirectional axis, wherein the diameter of the flange segment is larger than the diameter of the second shaft segment, the first shaft segment has an internally threaded hole, the support plate has a through hole for assembling the second shaft segment, and one end of the flange segment abuts against the support plate; wherein the opening edge of the through hole has a first chamfer, the shaft end of the first shaft segment has a second chamfer, and the first chamfer and the second chamfer together form an annular groove; a first weld connects the edge of the flange segment and the support plate, and a second weld fills the space between the first chamfer and the second chamfer.

[0006] As a further improvement of this utility model, the side of the flange segment includes a convex curved surface and a chamfered surface, with two convex curved surfaces and two chamfered surfaces arranged alternately, the two chamfered surfaces being parallel to each other, and the first weld being located on the convex curved surface.

[0007] As a further improvement of this utility model, there are two first welds, each with a C-shaped trajectory, and the two first welds are arranged symmetrically to each other; the axis of symmetry of the two first welds is perpendicular to the length direction of the support plate.

[0008] As a further improvement of this utility model, the chamfer size of the first chamfer and the chamfer of the second chamfer are equal, the chamfer angle of the first chamfer and the chamfer of the second chamfer are equal, and the cross-sectional profile of the annular groove is V-shaped.

[0009] As a further improvement of this utility model, the cross-section of the pallet component is L-shaped.

[0010] As a further improvement of this utility model, the shaft length of the second shaft segment is equal to the shaft length of the through hole.

[0011] As a further improvement of this utility model, the diameter of the first shaft segment is greater than the diameter of the second shaft segment, and the shaft length of the first shaft segment is greater than the shaft length of the second shaft segment.

[0012] The beneficial technical effects of using the bushing-equipped actuator foot plate of this application are: The bushing is assembled with the support plate through the through hole of the second shaft section, and one end of the flange section abuts against the support plate, which can achieve precise pre-positioning of the bushing and the support plate, avoid relative displacement during subsequent welding, and lay a stable foundation for the welding process.

[0013] The connection strength is enhanced by incorporating a double-weld structure. The first weld connects the flange edge to the support plate, fixing their radial relative positions. The second weld fills the annular groove formed by the first and second chamfers, further strengthening the connection between the bushing and the support plate. This design distributes stress, reducing stress concentration issues that are common with single welds, thereby improving the load-bearing capacity and fatigue resistance of the foot plate.

[0014] The annular groove formed by the first and second chamfers provides precise filling space for the second weld, allowing the second weld to fill the groove perfectly, preventing the weld from bulging outwards, and effectively ensuring the flatness of the footplate surface.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, an actuator foot support plate with a bushing is provided, comprising: a support plate 1; and a bushing 2, as shown in the figure. Figure 1 , Figure 2 As shown, along a unidirectional axis, it sequentially includes a first shaft segment 202, a flange segment 203, and a second shaft segment 204. The diameter of the flange segment 203 is larger than the diameter of the second shaft segment 204. The first shaft segment 202 has an internally threaded hole 201. The support plate 1 has a through hole 101 for the second shaft segment 204 to pass through. One end face of the flange segment 203 abuts against one side of the support plate 1. Wherein, as... Figure 3 As shown, the opening edge of the through hole 101 has a first chamfer 102, and the shaft end of the first shaft segment 202 has a second chamfer 207, as... Figure 6 As shown, the first chamfer 102 and the second chamfer 207 are joined together to form an annular groove 4. The edge of the flange section 203 is connected to the support plate 1 by a first weld 3, and the space between the first chamfer 102 and the second chamfer 207 is filled by a second weld 5.

[0019] From an axial perspective, both the first chamfer 102 and the second chamfer 207 are annular, with the first chamfer 102 located on the outer ring of the second chamfer 207. The first weld 3 is the weld at the right-angled inside corner, while the second weld 5 fills the annular groove 4. Furthermore, the second weld 5 needs to be ground smooth after welding to prevent any false welds. Figure 4 The first weld 3 is shown using a fish-scale pattern, while the annular groove 4 is clearly visible. Figure 6The second weld 5 is not shown in the image.

[0020] The beneficial effects of adopting the above technical solution are: the internal threaded hole 201 of the bushing 2 provides a place for threaded assembly, and this application mainly focuses on how to improve the connection strength at this point. First, one end of the bushing 2 is inserted into the support plate 1 for pre-fixation. Then, two welds with different positions and shapes are used to improve the tightness of the connection. The first weld 3 can have a weldable right-angled inside corner. The annular groove 4 formed by the two chamfers can fill the space of the second weld 5, which not only provides the welding position of the second weld 5, but also prevents the second weld 5 from protruding after welding, ensuring the flatness at this point.

[0021] In some other embodiments of the present invention, the side of the flange section 203 includes a convex curved surface 205 and a chamfered surface 206. The two convex curved surfaces 205 and the two chamfered surface 206 are arranged alternately, and the two chamfered surface 206 are parallel to each other. The first weld 3 is located on the convex curved surface 205.

[0022] The beneficial effects of adopting the above technical solution are: the planar part 206 is to narrow the local roughness of the flange section 203 so that the flange section 203 does not protrude from the surface of the support plate 1, while ensuring that the first weld 3 of the convex curved part 205 has sufficient length and the radius of curvature can also be large.

[0023] like Figure 4 As shown, in some other embodiments of this utility model, there are two first welds 3, each with a C-shaped trajectory, and the two first welds 3 are arranged symmetrically to each other. The axis of symmetry of the two first welds 3 is perpendicular to the length direction of the support plate 1.

[0024] The beneficial effects of adopting the above technical solution are: the two symmetrically arranged C-shaped first welds 3 make the welding force distribution uniform, enhance the stability and symmetry of the connection between the bushing 2 and the support plate 1, reduce welding deformation, and improve the overall structure and durability.

[0025] In some other embodiments of this utility model, the chamfer size of the first chamfer 102 and the chamfer size of the second chamfer 207 are equal, the chamfer angle of the first chamfer 102 and the chamfer angle of the second chamfer 207 are equal, and the cross-sectional profile of the annular groove 4 is V-shaped.

[0026] The beneficial effects of adopting the above technical solution are: the equal size and angle of the first chamfer 102 and the second chamfer 207 form a regular V-shaped annular groove 4, which provides a consistent filling space for the second weld 5, ensuring that the weld is uniform and firm, and improving the welding quality and connection strength.

[0027] In some other embodiments of this utility model, the pallet 1 is composed of two integral flat plates, the pallet 1 is a bent piece, and the cross-section of the pallet 1 is L-shaped.

[0028] The beneficial effects of adopting the above technical solution are: the L-shaped cross section of the pallet component 1 simplifies the structural design, facilitates bending processing, enhances the rigidity and installation adaptability of the pallet component 1, and improves the overall stability of the foot support.

[0029] In some other embodiments of this utility model, the shaft length of the second shaft segment 204 is equal to the shaft length of the through hole 101.

[0030] The beneficial effects of adopting the above technical solution are: the shaft length of the second shaft section 204 is equal to the shaft length of the through hole 101, so as to achieve a tight fit between the bushing 2 and the support plate 1, eliminate assembly gaps, and improve positioning accuracy and connection stability.

[0031] In some other embodiments of this utility model, the diameter of the first shaft segment 202 is greater than the diameter of the second shaft segment 204, and the axial length of the first shaft segment 202 is greater than the axial length of the second shaft segment 204.

[0032] The entire bushing 2 is treated to prevent it from being baked.

[0033] The beneficial effects of adopting the above technical solution are: the diameter and shaft length of the first shaft section 202 are greater than those of the second shaft section 204, which enhances the overall structural strength of the bushing 2, especially the load-bearing capacity of the internal threaded hole 201 area, and ensures the reliability and durability of the threaded connection.
