Description

A kind of unlatching holding meanss of the luggage-boot lid for vehicle

Technical field

Of the invention and a kind of unlatching holding meanss of the luggage-boot lid for vehicle are used for vehicle row more particularly to one kind The friction retention devices of the opening hinge of boot cover.

Background technique

In the existing vehicles, as shown in Figure 1, being equipped with hinge 4 on the rear bulkhead 3 in the rear side vehicle body 1 of vehicle One end, the other end of hinge 4 are installed on luggage-boot lid 2.Hinge 4 is on the hinge base 5 of rear bulkhead 3.For existing For baggage-compartment release system, when deck-lid release and closing, the articulate arm 6 of gooseneck tubulose is in hinge base 5 It is upper to generate friction torque to resist the quick unlatching of the luggage-boot lid under torsional spring effect and quick closedown, but existing hinge is living The articulated structure of swing arm 6 and hinge base 5 simply by the casing being fixedly connected with articulate arm 6 inner surface and and hinge Friction between the outer surface for the bushing that axis is fixedly connected provides friction torque, cannot then generate sufficiently large friction and turns round Square so that luggage-boot lid under the effect of torsion spring be easy to appear quickly open and quick closedown, to bring danger.

Summary of the invention

The technical problem to be solved by the invention is above-mentioned defect existing in the prior art is overcome, propose a kind of for opening The open system of the torsion spring type of vehicle trunk lid is opened, sufficiently large friction torque can be generated, is being turned round to avoid luggage-boot lid Quick unlatching and quick closedown under spring effect, so as to improve the safety of open system, while being easier to control open system Maneuvering performance, it is easier to achieve the effect that Customer Satisfaction.

According to an aspect of the invention, it is proposed that a kind of unlatching holding meanss of the luggage-boot lid for vehicle, comprising: peace Hinge base on the rear bulkhead of the rear of vehicle；One end is hingedly attached to the articulate on the hinge base The other end of arm, the articulate arm is connected to the luggage-boot lid of vehicle；It is fixedly attached to the two side walls of hinge base On hinge axis, the bushing being fixedly installed on hinge axis, the casing being slidably mounted on the outside of bushing, the hinge Lever arm is fixedly connected with casing, and casing is rotated with the rotation of articulate arm and relative to bushing, is mounted on the hinge The outer surface of the limiting device of the inside of pedestal, the limiting device and described sleeve pipe formed frictional fit and shape cooperation to So that luggage-boot lid is able to maintain the position opened at one.

Preferably, the limiting device includes that the limited block shell being fixedly attached on the hinge base and setting exist The spring and sliding block of the limited block enclosure interior, one end of the spring are resisted against on the inner surface of limited block shell, spring The other end be resisted against on the inner surface of sliding block, so that spring generates outside biasing force to sliding block, so that sliding block The appearance face bonding of outer end face and casing.

Preferably, the limited block shell is fixed on the roof of hinge base by fastener.

Preferably, be arranged on the outer surface of described sleeve pipe it is fluted, when casing is suitable as articulate arm turns to When position, the groove of casing is engaged with the outer end face of sliding block, so that a counter stopper is formed, so that luggage case is reliably Stop is maintained on an open position.

Preferably, the outer end face of the sliding block has coarse outer surface.

Preferably, opposite limiting device there are two being respectively set in the two sides of casing.

Preferably, the articulate arm is gooseneck.

According to another aspect of the invention, it is proposed that a kind of motor vehicles, including the above-mentioned luggage-boot lid for vehicle Open holding meanss.

Specific embodiment

Fig. 2-4 shows the hinge means according to the present invention for luggage-boot lid, the hinge of the gooseneck tubulose of hinge means Chain lever arm 6 is hingedly mounted on hinge base 5, and wherein hinge axis 8, which is permanently connected, is supported on two sides of hinge base 5 On wall, it is fixedly installed bushing 11 in hinge axis 8, a casing 9 is slidably mounted in the outside of bushing 11, the hinge of gooseneck shape Chain lever arm 6 is fixedly connected with casing 9, and such casing 9 is rotated with the rotation of articulate arm 6 and relative to bushing 11, in Be articulate arm 6 an end with and the articulated structure of hinge base 5 pass through the casing that is fixedly connected with articulate arm 6 Friction between 9 inner surface and the outer surface for the bushing 11 being fixedly connected with hinge axis 8 provides friction torque, due to casing Manufacture build-up tolerance and abrasion between 9 and bushing 11, so that the two cannot often generate sufficiently large friction torque, thus So that luggage-boot lid under the effect of torsion spring be easy to appear quickly open and quick closedown, to bring danger.Then, according to this A limiting device 7 is fixedly mounted in the inside of hinge base 5 in one embodiment of invention, the limiting device 7 and rotatable The outer surface of casing 9 forms a frictional fit, to provide an additional sufficiently large friction torque to articulate arm 6 To resist the quick unlatching and quick closedown of the lower luggage-boot lid of torsional spring effect, thus avoid luggage-boot lid it is quick open with fastly It is dangerous that speed closes bring.

In conjunction with shown in Fig. 5-6, the specific structure of limiting device 7 according to the present invention is more specifically shown, wherein The two sides of casing 9 are respectively set there are two opposite limiting device, and limiting device includes limited block shell 13, spring 14, sliding block 15 and fastener 16, wherein limited block shell 13 is fixedly attached on hinge base 5 by fastener 16, and sliding block 15 and spring 14 are pacified Mounted in the inside of limited block shell, one end of spring 14 is resisted against on the inner surface of limited block shell 13, the other end of spring 14 It is resisted against on the inner surface of sliding block 15, so that spring 14 generates an outside biasing force, the outer end of sliding block 15 to sliding block 15 Face and the outer surface of casing 9 form frictional fit, specific as shown in Figure 4.In addition, on a position of the outer surface of casing 9 It is additionally provided with groove 91, as shown in fig. 7, when casing 9 turns to suitable position with articulate arm 6, the groove 91 of casing 9 It is engaged with the outer end face of sliding block 15, so that a counter stopper is formed, as shown in figure 8, so that luggage case reliably stops It is maintained on an open position.

According to one embodiment of present invention, the surface of the outer end face of sliding block 15 is coarse, to increase limiting device The outer end face of sliding block and the outer surface of casing between friction torque.

According to another embodiment of the invention, protrusion also can be set on the outer surface of casing so that casing 9 with When articulate arm 6 turns to suitable position, the protrusion of casing 9 is engaged with the outer end face of sliding block 15, to form a backstop Cooperation, is maintained on an open position so that luggage-boot lid reliably stops.

Although the present invention has been shown and described relative to embodiment, it will be appreciated by those of skill in the art that The scope of the present invention can not departed from and make a variety of changes and improve.
