Abstract
The utility model discloses a fatigue test device for a vehicle trunk lid. The fatigue test device comprises a trunk lid body, a frame connecting rod, an opening mechanism and an actuating element. The frame connecting rod is arranged on the trunk lid. The actuating element is used for pushing the frame connecting rod to move. The opening mechanism comprises a rope, a clamping jaw and a column. The clamping jaw comprises a clamping portion and a handle portion. One end of the rope is fixed on the frame connecting rod, while the other end of the same is fixed on the handle portion of the clamping jaw. The clamping portion of the clamping jaw clamps a rubber roll tightly, and the rubber roll is fixedly connected to the trunk lid body. The fatigue test device for the vehicle trunk lid has the feasibility of being tested under conditions of either a high or a low temperature since a sucker in the prior art is omitted; and the trunk lid is not directly pushed open by the actuating element, so protective function of the trunk lid under the condition that a first lever lock is unlocked is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of automobile test device, particularly a kind of fatigue experimental device of car boot cover.
Background technology
Along with the raising of people's living standard, automobile is also more and more closely bound up with people's life, and people are also more and more harsher to the performance requirement of automobile.According to the actual needs that people require the automobile various aspects of performance, the testing requirements of car boot cover also progressively improving, must be tested by car bonnet before automobile dispatches from the factory, and satisfies " hommization " requirement, and just anthropomorphic dummy's state designs.
Luggage-boot lid fatigue experimental device of the prior art has: 1, use sucker, utilize the opening procedure of the special construction realization luggage case of sucker, still this mechanism can only test at normal temperatures, can not satisfy the requirement of carrying out thermocycling; 2, directly push luggage-boot lid open with actuation element, but because it is bigger to open the force rate of luggage-boot lid needs, and then need actuation element can produce bigger thrust, if the situation that the lock of the one-level on the luggage-boot lid is not opened, actuation element will cause very big injury to car bonnet.
Summary of the invention
At the problems referred to above that the fatigue experimental device of luggage-boot lid in the prior art exists, the utility model provides a kind of simple in structure, dependable performance and is convenient to the fatigue experimental device that is used for opening car boot cover of installation and maintenance.
The technical solution of the utility model is:
A kind of car boot cover fatigue experimental device, comprise: luggage-boot lid, be arranged at framework connecting link on the luggage-boot lid, opening mechanism, be used for promoting the actuation element of framework connecting link motion, described opening mechanism comprises rope, jaw and cylinder, one end of described rope is fixed on the framework connecting link, the other end is fixed on the jaw, jaw tightly clamps cylinder, and described cylinder is fixedly connected on the luggage-boot lid.
As further improvement of the utility model, described cylinder is the cylindrical structure of rubber material.
As further improvement of the utility model, described jaw is held on the middle part of cylinder.
As further improvement of the utility model, described jaw comprises clamping part and shank, and an end of described rope is fixed on the framework connecting link, and the other end is fixed in the shank of jaw, and the clamping part of jaw tightly clamps cylinder.
The beneficial effects of the utility model are:
1, owing to avoid using employed sucker in the prior art, a kind of car boot cover fatigue experimental device of the utility model has the feasibility of testing under high low temperature condition;
2, owing to directly do not push luggage case open by actuation element, a kind of car boot cover fatigue experimental device of the utility model has effectively guaranteed under the situation that the one-level lock is not opened the protective effect to luggage-boot lid.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of luggage-boot lid fatigue experimental device of the prior art as shown in Figure 1.
The opening mechanism of this luggage-boot lid is to promote framework connecting link 3 with actuation element 4 to move in a circle, and because luggage-boot lid 1 links to each other by sucker 8 with framework connecting link 3, and then luggage-boot lid 1 is moved in a circle.Sucker 8 is a kind of sealing lip limits of being with, and forms a provisional seal cavity contacting the back with the absorbate body, by taking away or the air of thin seal cavity the inside, produces the external and internal pressure difference and a kind of pneumatic apparatus of carrying out work.Wherein the principle of work of sucker 8 is because the special construction of sucker 8, with can form a provisional confined space after object contact, by pneumatic line or certain device, take away or thin confined space inside air.Like this, the air pressure of confined space the inside just has been lower than an extraneous atmospheric pressure.So the external and internal pressure difference has produced.The atmospheric pressure of outside can press together luggage-boot lid 1 and sucker 8 firmly.But there is its limitation in this mechanism, can only test at normal temperatures, can not satisfy the requirement of carrying out thermocycling.
The fatigue experimental device of another kind of luggage-boot lid as shown in Figure 2 in the prior art.
The fatigue experimental device of this luggage-boot lid directly is fixed on actuation element 4 in the luggage-boot lid 1, directly carries out boot cover 1 with actuation element 4 and realizes opening This move.Though it is simple that this mechanism seems, but exist a lot of problems: because it is bigger to open the force rate of luggage-boot lid needs, and then need actuation element can produce bigger thrust, if the situation that the lock of the one-level on the luggage-boot lid is not opened, actuation element will cause very big injury to car bonnet.
The structure of a kind of car boot cover fatigue experimental device of the utility model as shown in Figure 4, it uses constitutional diagram as shown in Figure 3.
A kind of car boot cover fatigue experimental device of the utility model comprises: luggage-boot lid 1, be arranged at framework connecting link 3 on the luggage-boot lid 1, opening mechanism 2, be used for promoting the actuation element 4 of framework connecting link 3 motions, described opening mechanism 2 comprises rope 5, jaw 6 and cylinder 7, described jaw 6 comprises clamping part and shank, one end of described rope 5 is fixed on the framework connecting link 3, the other end is fixed in the shank of jaw, the clamping part of jaw 6 tightly clamps cylinder 7, and described cylinder 7 is fixedly connected on the luggage-boot lid 1.Cylinder 7 can adopt the cylindrical structure of non-metallic material (for example rubber).Jaw 6 is held on the cylinder 7.
The implementation procedure of a kind of car boot cover fatigue experimental device of the utility model is as follows:
Jaw 6 is clamped on the rubber volume, the rubber volume is fixed together with luggage-boot lid 1, rope 5 wherein is fixed on above the framework connecting link 3.Its working method is: promote framework connecting link 3 with actuation element 4 and move in a circle, because an end of rope 5 is connected on the framework connecting link 3, the other end of rope 5 is connected with jaw 6, and jaw 6 tightly is clamped on the cylinder 7 that is fixed on the luggage-boot lid 1, framework connecting link 3 will drive boot cover 1 and do the concentric circles motion with framework connecting link 3, thereby realized that actuation element 4 drives luggage-boot lid 1 and moves in a circle, and then realized opening the purpose of luggage-boot lid 1.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
