Description

Automobile trunk torsion bar spring free of paint dropping

Technical Field

The utility model relates to an automobile assembling technical field especially relates to an exempt from car trunk torsion bar spring of lacquer.

Background

The torsion bar spring of the trunk is a product which is used for providing power for opening and keeping the opening state of the trunk in the trunk opening and closing mechanism of the three-compartment vehicle.

The prior art is that the copper bush is installed at the contact point position of the contact with the torsion bar spring on the trunk hinge to reduce friction abnormal sound and abrasion of the torsion bar and the hinge in the relative motion process, but in the actual production, the copper bush is installed on the hinge in the opening and closing process of the trunk, but the copper bush can shift in the long-term relative operation friction, so the problem of paint falling can occur even at the position of the copper bush installed on the hinge, the problem of paint falling of the torsion bar spring at the contact position of the torsion bar spring and the hinge is more serious, and the problems of abrasion and abnormal sound exist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an exempt from car trunk torsion bar spring that falls lacquer, it can solve among the prior art torsion bar spring wearing and tearing fall the problem of lacquer.

A paint-dropping-free torsion bar spring of an automobile trunk comprises a torsion bar spring, a hinge base and a hinge bracket, wherein the hinge bracket is arranged on the hinge base, and the torsion bar spring is respectively connected with the hinge base and the hinge bracket; and a sheath is arranged at the joint of the torsion bar spring and the hinge base and the hinge support, and the sheath is L-shaped.

Furthermore, a copper bushing is further installed at the joint of the torsion bar spring and the hinge base and/or the hinge support. The copper bush can protect the torsion bar spring, and under the combined action of the copper bush and the sheath, the torsion bar spring can be further protected, and the torsion bar spring is more effectively prevented from being abraded in long-term use.

Further, the sheath is installed on the torsion bar spring and is located between the torsion bar spring and the copper bush. The sheath is installed between torsion bar spring and copper bush can make the more inseparable fixed with torsion bar spring of sheath, avoids the condition that the sheath removed.

The hinge comprises a torsion bar spring, a hinge base and a hinge bracket, wherein the hinge bracket is arranged on the hinge base, and the torsion bar spring is respectively connected with the hinge base and the hinge bracket; the protective sleeve is arranged at the joint of the torsion bar spring, the hinge base and the hinge support, and is L-shaped, and the joint of the torsion bar spring, the hinge base and the hinge support is arranged at the turning part of the torsion bar spring, so that the L-shaped protective sleeve can effectively protect the joint of the torsion bar spring, the hinge base and the hinge support, the problem of abrasion and paint dropping in long-term use is prevented, and the L-shaped protective sleeve can be prevented from shifting.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Referring to fig. 1 to 4, the torsion bar spring of the automobile trunk without paint dropping provided by the embodiment of the application comprises a torsion bar spring 2, a hinge base 3 and a hinge bracket 4, wherein the hinge bracket 4 is installed on the hinge base 3, and the torsion bar spring 2 is respectively connected with the hinge base 3 and the hinge bracket 4; and a sheath 1 is arranged at the joint of the torsion bar spring 2 and the hinge base 3 and the hinge support 4, and the sheath 1 is L-shaped.

In a preferred embodiment, a copper bushing 5 is further installed at a connection point of the torsion bar spring 2 and the hinge base 3 and/or the hinge bracket 4. Copper bush 5 can protect torsion bar spring 2, under the combined action of copper bush 5 and sheath 1, can further protect torsion bar spring 2, more effectual torsion bar spring 2 of avoiding produces wearing and tearing in long-term the use.

Further preferably, the sheath 1 is mounted on the torsion bar spring 2 and is located between the torsion bar spring 2 and the copper bushing 5. The sheath 1 is arranged between the torsion bar spring 2 and the copper bush 5, so that the sheath can be more tightly fixed with the torsion bar spring 2, and the situation that the sheath 1 moves is avoided.
