Description

Technical Field

[0001] This invention relates to a non-fixed vehicle roof with a sliding roof panel, specifically a movable vehicle roof. Background Technology

[0002] Car roofs or sunroofs are widely used in various vehicle types such as trucks, SUVs, and sedans. However, existing car roofs and sunroofs offer limited visibility and low efficiency, failing to meet user needs. Summary of the Invention

[0003] The purpose of this invention is to provide a movable car roof that fundamentally solves the above-mentioned problems. It has the advantages of simple and compact structure and convenient and quick use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: the movable car roof includes a roof frame, a pair of guide rails, a fixed panel mounted between the guide rails, a pair of mechanical assemblies that are slidably limited within the guide rails, and a sliding panel that can overlap the fixed panel. Its key technical features are:

[0005] The mechanical assembly includes three slider assemblies, three lifting arm assemblies, a panel bracket riveted to and supported by each lifting arm assembly, and connecting rods that are staggered between adjacent slider assemblies via front and rear connecting ends;

[0006] The front slider assembly is provided with a front slider front groove and a front slider rear groove that are symmetrically arranged. The starting and ending sections of the front slider front groove are set horizontally and smoothly transition from low to high.

[0007] The middle slider assembly is provided with a middle slider groove that smoothly transitions from low to high. The starting section of the middle slider groove is horizontal, the middle section arches upward, and the key section smoothly transitions downward.

[0008] The rear slider assembly is provided with a front slide groove and a rear slide groove of the rear slider arranged from front to back. The starting section of the front slide groove of the rear slider is set horizontally and transitions downward. The starting and ending sections of the rear slide groove of the rear slider are set horizontally and transition from low to high.

[0009] Furthermore, the panel bracket is alternately provided with riveting parts and protruding mounting holes along its length. The sections where the riveting parts and mounting holes are located are respectively arranged in a concave and convex manner on the inner and outer sides of the surface where the main body of the panel bracket is located, and the riveting parts are located at the front and rear outer ends of the panel bracket.

[0010] Furthermore, the connecting rod includes a straight body and T-shaped connecting portions at the front and rear ends of the body. The connecting portions are recessed inward on the side facing the slider assembly, and the connecting portions at both ends are arranged in a relatively convex manner.

[0011] Furthermore, the upper surface of the strip-shaped main body of the connecting rod is provided with a notch along the width direction.

[0012] The beneficial effects of this invention are as follows: In terms of the overall technical solution, a mechanical assembly guided by a guide rail located on the outside of the fixed panel is adopted, thereby achieving movement of a larger sliding panel area and providing a wider overhead view. When the sliding panel is opened or closed, the entire sliding panel moves upward or downward, resulting in higher operational efficiency. The car's movable roof or sunroof glass can open from front to back or from back to front, offering strong adaptability to various vehicle types. It is not limited to car movable roofs and sunroofs but is also suitable for car trunks, tailgates, etc.

[0013] With the effective support of multiple boom components, greater load-bearing capacity can be provided, which can then be used for larger movable roofs or sunroofs to meet the need for a wide field of vision.

[0014] In terms of specific structure, a mechanical assembly consisting of three slider components and three lifting arm components is adopted. At the same time, the panel support is riveted to the three lifting arm components, which improves the buffering characteristics of the panel support.

[0015] Each lifting arm assembly slides within the groove of its corresponding slider assembly via its support portion, thereby driving the panel support to rise and fall when the slider assembly is driven along the slide rail.

[0016] The connecting rod has T-shaped connecting parts at both ends that mate with the ends of the slider assembly. The relative arrangement of the outer and inner sides of the T-shaped structure at both ends ensures the force balance of the slider assembly during its forward and backward movement, preventing the connecting rod from coming off the connecting part of either slider assembly.

[0017] Each connecting part and the corresponding side of the slider assembly adopts a concave structure, effectively improving elasticity. Meanwhile, because the stiffness of the T-shaped connecting part and the extension in the same direction as the connecting rod is significantly less than that of the connecting rod as a whole, when the slider assembly moves along the guide rail...

[0018] The slider assembly located at the lower position of the slide rail presses down on the connecting rod, causing the T-shaped connecting part to deflect within the connecting part of the slider. This extension is the first to bend under force, and the downward pressure continues to be transmitted to the entire connecting rod through the extension. Combined with the elastic force generated by the porous structure inside the connecting rod and the transverse notch on the connecting rod, the slider assembly bends to a certain extent, thereby adapting to the guide rail in the length direction. This ensures that the slider assembly is stably supported within the guide rail while providing sufficient bending toughness. Attached Figure Description

A middle slider groove 1225 is provided in the middle of the main structure. The front part of the middle slider groove 1225 is horizontal and the rear part is arched upward. The arched part of the middle slider groove 1225 protrudes outward, and the protruding edge cooperates with the limiting parts 1223 and 1224 at its front and rear. A middle slider locking part 1226 is also provided at the rear of the middle slider groove 1225.

[0044] like Figure 3e As shown, the rear slider assembly 123 includes a strip-shaped main structure. The front side of the main structure has a rear slider connecting part 1237 that mates with the rear connecting part 152 of the rear connecting rod 15. The top and bottom sides of the main structure are respectively provided with a rear slider front sliding part 1231, a rear slider front limiting part 1233, a rear slider rear sliding part 1232, and a rear slider rear limiting part 1234.
