Abstract

The invention discloses an integrated cross-bar-free support for mounting a roof luggage frame of an automobile. The installation cost can be obviously reduced, and a cross bar is not required to be installed; the wind resistance is reduced during driving, and the obstacles that the panoramic sunroof cannot be opened are eliminated; the stress structure is optimized, and the connection rigidity is increased; the connecting piece has good concealment and safe use, and can prevent hooking; simple structure, easy assembly and disassembly, and no change of the luggage frame structure.

Description

Novel horizontal pole support is exempted from with integration to installation of car roof frame

Technical Field

The invention relates to a connecting component for a roof luggage frame and a vehicle body longitudinal rod of an automobile, which ensures that the roof luggage frame does not need to be provided with a cross rod and a fixed support does not need to be welded on the roof luggage frame.

Background

Many off-road vehicle users like to install luggage frames on the vehicle roof, and the storage space and the function are expanded. Traditional roof luggage frame's installation, need rely on roof vertical pole and horizontal pole, at first adorn the horizontal pole dress on the vertical pole, then the roof frame is connected with the horizontal pole through corresponding component, it is many to cause the atress node, installation connection rigidity is lower, the roof frame easily displaces, rock, the abnormal sound easily takes place, adopt this kind of mode simultaneously, place the roof frame in because of the horizontal pole under, the windage is great, there is the motorcycle type in panorama skylight, the horizontal pole still can hinder opening in skylight, in addition, because of horizontal pole and vertical pole connecting piece, the vertical pole links to each other with roof frame connecting piece, the bolt of connecting piece and connecting piece exposes, there is the hook, hang the phenomenon, easily lead to operating personnel injured or deposit article and hang bad problem.

Disclosure of Invention

The invention provides an integrated cross-bar-free support, which directly combines and fixedly connects a luggage frame on the top of an automobile with a longitudinal bar on the top of the automobile, realizes the functions of replacing a cross bar, connecting the cross bar with the longitudinal bar and connecting the cross bar with the top frame, and directly fixes the luggage frame on the longitudinal bar, thereby reducing stress nodes, leading the stress to be more reasonable, increasing the connection rigidity, reducing the windward area due to the cancellation of the cross bar, theoretically reducing the wind resistance and solving the problem of blocking the opening of a skylight. Connecting components are reduced, and hidden bolts prevent articles from being hooked. The support connection mode does not need to weld auxiliary components such as a support and the like on the roof frame, does not need to change the structure of the luggage frame, and has simple connection, easy operation and beautiful form.

The scheme adopted by the invention is as follows: the support body of the support member with the square cross section and the width slightly wider than the roof cross bar and the roof frame bearing pipe is made of steel, the upper end of the support body is cut into a longitudinally through clamping groove according to the cross section appearance and the width of the bearing pipe of the roof frame, the lower end of the support body is correspondingly cut into a longitudinally through clamping groove consistent with the cross section of the roof cross bar, a steel strip-shaped locking belt extends from the upper end and the lower end of the support member, the steel strip-shaped locking belt respectively surrounds the upper side of the roof frame bearing pipe and the bottom of the roof longitudinal bar and then meets the inner side of the support body, the support body is locked by two countersunk hexagon socket head bolts, the roof luggage frame and the roof longitudinal bar.

The invention has the beneficial effects that: the installation cost is reduced, and a cross bar is not required to be installed; the wind resistance is reduced during driving, and the obstacles that the panoramic sunroof cannot be opened are eliminated; the stress structure is optimized, and the connection rigidity is increased; the connecting piece has good concealment and safe use, and can prevent hooking; simple structure, easy assembly and disassembly, and no change of the luggage frame structure.

Drawings

The invention is further illustrated by the following figures and examples

FIG. 1 is an example of a stent

FIG. 2 is a view showing a mounting structure of a bracket

FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2

In the figure, 1, a support body, 2, an upper extension locking belt, 3, a lower extension locking belt, 4, a locking bolt, 5, a roof luggage frame, 6 and a roof longitudinal rod

The specific implementation mode is as follows:

the clamping groove at the upper end of the support supporting body shown in the figure 2 (1) clamps the roof luggage frame (5), the clamping groove at the lower end clamps the roof longitudinal rod (6), the upward extending locking belt (2) upwards bypasses the roof luggage frame (5) and the downward extending locking belt (3) downwards bypasses the roof longitudinal rod (6), and then the upward extending locking belt and the downward extending locking belt meet at the inner side of the support supporting body (1) and the lower part of the roof luggage frame (5), and are locked and fixed by the locking bolt (4). (1) The support supporting body enables the roof frame to be jacked away from the roof longitudinal rod (6) by a certain distance, and the opening requirement of the panoramic sunroof is met.

As shown in fig. 3, the support body has a rectangular cross section.

In the example of the rack shown in fig. 1, four racks are used for each luggage frame.

Claims

1. The utility model provides a novel horizontal pole support is exempted from with integration to installation of car roof luggage frame, characterized by: the clamping grooves at the upper end of the support supporting body clamp the roof frame, the clamping grooves at the lower end clamp and support the roof longitudinal bar, and the upper extension locking belt and the lower extension locking belt respectively surround the upper side of the roof luggage frame and the bottom of the roof longitudinal bar and then meet the inner side of the support and are locked and fixed by bolts.

2. The integrated crossbar-free bracket of claim 1, wherein: the cross section of the support supporting body is a rectangular rigid body with the width slightly larger than the width of the longitudinal rod and the width of the cross section of the longitudinal bearing pipe of the roof frame, the upper end of the support supporting body is cut into longitudinally-communicated clamping grooves according to the shape and the size of the cross section of the bearing pipe of the roof frame, and the corresponding lower end of the support supporting body is cut into longitudinally-communicated clamping grooves consistent with the cross section of the roof cross bar and is responsible for connecting and supporting the main gravity of the roof.

3. The integrated crossbar-free bracket of claim 1, wherein: last prolong and the locking band of downwardly extending be banded structure, extend from the supporter lateral surface, at the inboard locking that converges of supporter, it is fixed to be responsible for the locking, prevents to take place the displacement and rock between luggage frame and support and roof longitudinal bar.

4. The integrated crossbar-free bracket of claim 1, wherein: the support mounting can be completed only by locking the locking bolts on the upper extension belt and the lower extension belt, no hole or pressure groove is needed on the roof luggage frame, and no auxiliary components such as accessories and welding supports are needed to be mounted.
