Abstract

The utility model relates to the field of parts of cars, in particular to a car trunk lid hinge. The car trunk lid hinge comprises arch-shaped hinge bodies arranged between a trunk body and a trunk lid. Each arch-shaped hinge body is composed of an arch-shaped hinge and a hinge base, wherein the arch-shaped hinge and the hinge base are hinged through an articulated shaft. The arch-shaped hinge bodies are two in number and are arranged coaxially. Two torsion bars are symmetrically arranged between the two arch-shaped hinge bodies. An adjustable spring is arranged between one arch-shaped hinge and one hinge base. Due to the arrangement of the adjustable springs, under the situation that the torsion of the torsion bars decreases, additional compensating torque is provided for assisting in the opening of the trunk lid. Due to the fact that the adjustable springs can be adjusted, the adjustment of the adjustable springs is conducted according to the decreasing degree of the torsion of the torsion bars, the torque for the opening of the trunk lid is increased through the increase of the tensile force of the adjustable springs, namely appropriate compensating torque can be provided, and the car trunk lid hinge is quite convenient and reliable to use. Meanwhile, the car trunk lid hinge is also very simple in structure and easy to realize.

Description

The car trunk cover hinge

Technical field

The utility model relates to the auto parts and components field, particularly a kind of car trunk cover hinge.

Background technology

The direct opener of luggage-boot lid of the prior art mainly comprises the arc hinge that arranges between boot casing and the luggage-boot lid, as shown in Figure 1, the arc hinge 1 that constitutes arc hinge is hinged by jointed shaft 3 with hinge base 2, two of arc hinge coaxial arrangement, between two arc hinge A, the

B torsion bar

4,5 is set,

torsion bar

4,5 two ends link to each other with two arc hinge A, B respectively, and the moment of torsion that closes that

torsion bar

4,5 pretwist torsion constitute the moment of torsion that rotates in the same way orders about luggage-boot lid and makes opening movement.The concrete structure of arc hinge 1 as shown in the figure, it is arc bend pipe, one end of arc hinge 1 links to each other with hinge base 2, the other end and luggage-boot lid are connected, one end hook head button of torsion bar 4 is not on the arc hinge 1 of a side, the other end gib head button of torsion bar 4 not on the hinge base 2 of opposite side, the arrangement symmetry of the arrangement of torsion bar 5 and torsion bar 4.

This baggage compartment lid hinge is simple in structure, saves installing space; But because the luggage-boot lid most of the time all is in closed condition, this moment,

torsion bar

4,5 was under the acrotorque state, and this makes torsion bar 4, the decay of 5 torsion very fast.Use torsion bar 4 after a period of time, 5 torsion deficiency, luggage-boot lid be difficult to open or open after under external force (as wind) fall easily, cause and use inconvenience, even personnel's injury.

The utility model content

The purpose of this utility model is to provide a kind of car trunk cover hinge, and is simple in structure, uses reliable.

For realizing above purpose, the technical solution adopted in the utility model is: a kind of car trunk cover hinge, comprise the arc hinge that arranges between boot casing and the luggage-boot lid, constitute arc hinge, the hinge base of arc hinge, hinged by jointed shaft, described arc hinge coaxial arrangement has two, and two torsion bars of symmetric arrangement are provided with adjustable springs between arc hinge and hinge base between two arc hinges.

Compared with prior art, there is following technique effect in the utility model:

The setting of adjustable springs, under the situation of torsion bar torsion decline, provide extra compensation torque the auxiliary luggage-boot lid of opening, because adjustable springs is adjustable, implement the adjusting of adjustable springs according to torsion bar torsion degree of damping, increase the moment of torsion of the unlatching of luggage-boot lid by the pulling force that improves adjustable springs, namely can provide the suitable compensation moment of torsion, very easy to use reliable; It is structurally also very simple to be somebody's turn to do design simultaneously, realizes easily.

Fig. 2 is the utility model car trunk cover hinge three-dimensional structure diagram;

Fig. 3 is the local enlarged diagram of Fig. 2.

The specific embodiment

Below in conjunction with Fig. 2, Fig. 3, the utility model done being described in further detail:

Consult Fig. 2, a kind of car trunk cover hinge, comprise the arc hinge 10 that arranges between boot casing and the luggage-boot lid, constitute arc hinge 11, the hinge base 12 of arc hinge 10, hinged by jointed shaft 13, described arc hinge 10 coaxial arrangement have two, symmetric arrangement two torsion bar 20a, 20b between two arc hinge 10a, 10b, and 12 of arc hinge 11 and hinge bases are provided with adjustable springs 30.When torsion weakened, the elastic force of spring can be regulated, and still can open luggage-boot lid by failure-free; Simultaneously, the spring force of adjustable springs 30 is adjustable, and like this, the adjusting according to torsion bar torsion degree of damping enforcement adjustable springs 30 can provide the suitable compensation moment of torsion, makes the dynamics of opening luggage-boot lid keep stable.

Consult Fig. 3, in the present embodiment, described adjustable springs 30 comprises coil spring 31, its stressed mode of operation is state of tension, be extension spring, an end captive joint hinge base 12 of described coil spring 31, the other end captive joint threaded block 32 of coil spring 31, screw thread in the threaded block 32 cooperates with the thread segment shaft of screw rod 33, and the rod head end of described screw rod 33 is fixedly connected on the shaft of arc hinge 11.By the axial location of adjusting screw(rod) 33 in threaded block 32, can realize the adjusting of spring length.Need to prove, if with the arc hinge 11 of an end captive joint of coil spring 31, screw rod 33 rod head end captive joint hinge bases 12, such setting also can meet the demands.

For the ease of connecting and changeing certain part, coil spring 31 is processed into hook-shaped with the end that hinge base 12 is fixed; The rod head end of described screw rod 33 is fixedly connected on connection hole on the arc hinge 11 by coupling link 34.

For guaranteeing stressed the best of spring, the shaft core line of described threaded block 32, screw rod 33 overlaps layout with the shaft core line of coil spring 31.

At the use initial stage, the pulling force of adjustable springs is reduced or do not produce pulling force, only depend on torsion bar 20a, 20b to realize the unlatching of luggage-boot lid; When torsion is decayed to some extent, when deck-lid release slowly maybe can't be opened, shorten the length of adjustable springs gradually, allow it provide suitable pulling force to drive the moment of torsion that arc hinge 11 rotates to increase, guarantee that boot cover is stable, realize breakdown action reliably.
