BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rudder tray cover durability test apparatus.

For example, a wagon-type vehicle or a sports-type multipurpose vehicle (RV, SUV, MPV) that has become popular in recent years is provided with a cargo loading space capable of accommodating various cargoes behind the rear seats. The floor of the cargo loading space, that is, the lower part of the floor, is provided with a luggage rack for receiving a lightening tool and various other necessary items.

The floor covering the luggage trays functions as a floor of the cargo carrying space and serves as a lid for the luggage trays. Therefore, the luggage train can be opened by lifting and holding the handle provided on the cover.

1 is a view for explaining a mounting structure of a luggage rack installed in a conventional RV type vehicle.

Referring to the drawings, it can be seen that a luggage rack 11 is installed at the bottom of a cargo loading space B provided at the rear of a seat of a vehicle A. Particularly, the cover 13 of the luggage rack 11 serves as a flat floor on the floor of the cargo loading space B. A handle 13f is provided at the outer end of the cover 13 so as to lift the cover 13 by holding the handle 13f.

FIG. 2 is a perspective view of the luggage train shown in FIG. 1; FIG.

As shown in the figure, the luggage rack 11 includes a storage tray 15 for providing a storage space, a cover (not shown) provided on the storage tray 15 for covering the storage tray 15 13).

The cover 13 takes a planar shape of a rectangular plate and has a fixing part 13c divided into two parallel folding lines x1 and x2 and a first opening part 13a and a second opening part 13b . The folding line means a portion folded at an angle of 90 degrees or less.

The fixing portion 13c is a portion fixed to the bottom plate of the vehicle. To this end, concave rectangular coupling grooves 13d are provided at both ends in the width direction of the fixing portion 13c. A screw hole 13e is formed in the inner bottom surface of the coupling groove 13d so that the fixing portion 13c can be fixed to the bottom surface of the vehicle using a screw (not shown).

The second opening 13b is a portion connecting the folding line x2 to the fixing portion 13c along the boundary line. The first opening 13a is connected to the second opening 13b. A folding line x1 is provided between the first opening 13a and the second opening 13b to provide the first opening 13a with respect to the second opening 13b, Can be folded. In addition, the first opening 13a is provided with a handle 13f to lift the first opening 13a in the direction of the arrow p.

FIGS. 3A to 3D are views sequentially showing the manner in which the riding trays shown in FIG. 2 are opened.

3A shows a state in which the cover 13 covers the storage tray 15. Fig. The cover 13 serves as a bottom plate of the vehicle and can open the storage tray 15 by holding the handle 13f in the direction of the arrow p if necessary.

Further, the fixing portion 13c is fixed to the vehicle and does not cover the storage tray 15. It is already mentioned that the fixing portion 13c is fixed to the floor of the vehicle through the coupling groove (13d in Fig. 2).

When the handle 13f is continuously lifted in the direction of the arrow p in the state of FIG. 3a, the first opening 13a and the second opening 13b finally pass through the process of FIGS. 3b and 3c, And the front edge portion of the first opening 13a is brought into contact with the fixing portion 13c. Of course, when the storage tray 15 is not required to be opened as a whole, that is, when a small object is simply inserted or removed, the first and second openings 13a and 13b need not be completely lifted as described above.

The folding line (x1, x2) repeatedly bends and spreads repeatedly even if the folding line (x1, x2) is within a slight angle range. This means that, in one cover 13, the folding lines (x1, x2) can be broken most quickly.

Accordingly, the manufacturing factory of the luggage rack 11 is required to repeatedly perform the opening / closing durability test for the cover 13 after the cover 13 is manufactured.

However, since there is no separate dedicated device for the repeated opening / closing durability test of the cover in the past, a very inefficient method of repeating folding by hand has been employed. It is practically impossible to do tensile fold tensile test by hand, so we had to finish the durability test of the product through at least several dozen repetitive tests. As a result, the durability of the manufactured products can not be grasped, and the durability data can not be accurately stored in the database, which can not be used to improve the performance of the luggage trays.

The present invention has been made in order to overcome the above problems, and it is possible to sufficiently perform the repeated opening / closing durability test of the cover covering the luggage trays, so that the durability of the produced cover can be accurately grasped and reflected in the product design, The present invention provides a durability test apparatus for a luggage train tray cover which enables a durability test.

In order to achieve the above object, the present invention provides a luggage compartment cover for a luggage rack installed at a lower portion of a floor, serving as a floor of a cargo loading space provided behind a seat in a vehicle, , The durability of the cover made of the opening portion adjacent to the fixing portion at the boundary of the folding line and pivoting to the upper portion if necessary to open the luggage tray is tested to provide an area for spreading the cover to be tested thereon A table horizontally fixing the fixing portion of the cover; An actuator installed at one side of the table and provided with an operating rod that is linearly moved in the longitudinal direction by receiving external pressure; A rack gear mounted on an end of the operation rod and linearly reciprocating in the longitudinal direction according to an operation of the actuator; A pinion gear engaged with the rack gear and rotated by an operation of the rack gear and having a rotation axis fixed to the rotation center;

The table also includes a pivot shaft spaced apart from the pinion gear so as to place the cover to be tested between the pinion gear and the pinion gear and having the same center of rotation as that of the pinion gear; A bearing rotatably supporting the pivot shaft; A second arm having a rear end fixed to the pivot shaft and pivotally moving in accordance with rotation of the pivot shaft and extending parallel to the first arm; A holder installed on the second arm and coupled to the opening of the cover to connect the opening and the second arm; And a connecting rod connecting the first arm and the second arm to each other to allow the second arm to follow the first arm and turn simultaneously.

In addition, the holder is configured to receive and fix the side edge portion of the cover opening portion in the inside thereof, and is rotatable about the pin in a pin connection with the arm.

In addition, the opening portion may include a second opening portion adjacent to the fixing portion, which is divided into two through one folding line, and a first opening portion adjacent to the second opening portion, And is fixed to both end portions.

The table is provided with a mounting block for horizontally fixing the stationary portion of the cover to the upper portion of the table, and a folding line for partitioning the stationary portion and the second opening portion is provided between the mounting block and the rotary shaft of the pinion gear .

The test apparatus may further include an output unit for displaying the number of operations of the actuator and the speed of the operation rod.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

4 is a perspective view illustrating a rugged tray cover durability testing apparatus according to an embodiment of the present invention.

Referring to the drawings, a cover durability testing apparatus 31 according to the present embodiment includes a table 33 provided with a horizontal surface on which a cover 13 to be tested is deployed, A controller 51 for controlling the driving unit, a driving unit for turning the first and second openings 13a and 13b of the cover 13 upward or downward as shown in FIG. 3, And an output unit 53 connected to the controller 51 and displaying the operation contents of the driving unit.

First, on the upper surface of the table 33, two mounting blocks 49 are fixed in a state of being spaced apart from each other in the width direction of the cover 13. The mounting block 49 provides an upper surface having a predetermined height from the upper surface of the table 33 and fixes the coupling groove 13d of the fixing portion 13c thereon. The cover 13 is spaced a predetermined height from the upper surface of the table 33 by the mounting block 49.

The driving unit includes an actuator 35 horizontally installed on one side of the table 33 and a plurality of actuators 35 fixed to the actuating rod 35b of the actuator 35 and reciprocating in the longitudinal direction by the operation of the actuating rod 35b A guide block 43 for slidably supporting the rack gear 37 and a pinion gear 39 disposed on the rack gear 37 and meshing with the rack gear 37, A rotating shaft 39a which is fixed to the both-side rotation center shaft portion of the pinion gear 39 and extends to the outside and a rear end portion of which is fixed to the rotating shaft 39a and which rotates by the rotation of the pinion gear 39; And includes an arm 45.

The actuator 35 is a conventional pneumatic actuator including a cylinder 35a supplied with air from the outside and an operating rod 35b extending outward from the cylinder 35a and reciprocating in the longitudinal direction . Although the actuator 35 is horizontally positioned on the support 59 in this embodiment, the mounting orientation of the actuator 35 can be changed as long as the pinion gear 39 can be rotated.

The rack gear 37 fixed to the end of the actuating rod 35b is a rack gear which is generally formed as a tooth on one side of a square pillar and has a guide groove 43 43a. The rack gear 37 is supported by the guide block 43 and reciprocates longitudinally in a horizontal state.

The pinion gear 39 rotates in the direction of arrow a or in the opposite direction by the operation of the actuator 35 in a state where the pinion gear 39 meshes with the rack gear at the top of the rack gear 37. A rotary shaft 39a fixed to both surfaces of the pinion gear 39 is rotatably supported by a bearing 41. [

In particular, the rotating shaft 39a is located between the folding lines x1 and x2. This will be described later.

The first arm 45 is a straight member extending in parallel to the rim of the side of the cover 13 with its rear end fixed to the rotation shaft 39a. Needless to say, the first arm 45 and the rotary shaft 39a are perpendicular to each other.

A holder 47 is provided at the end of the first arm 45. The holder 47 is a member having a substantially C shape and accommodates the side end portion of the first opening portion 13a therein. To this end, the holder 47 is provided with a fixing bolt 47a. The fixing bolt 47a serves to fix the first opening portion in the holder 47 by tightening the first opening portion 13a accommodated in the holder 47. [

Further, the holder 47 is connected to the pin 45a with respect to the first arm 45. Therefore, the holder 47 is rotatable in the direction of arrow c or the opposite direction.

On the other hand, a second arm 46 is provided on the opposite side with the cover 13 therebetween. The rear end of the second arm 46 is supported on the bearing 41 through the pivot shaft 57. The second arm 46 has the same size and structure as the first arm 45 and has a holder 47 at its distal end.

Particularly, in order to transfer the rotational force of the first arm 45 to the second arm 46, the first arm 45 and the second arm 45 are rotated so that the second arm 46 rotates simultaneously with the first arm 45, The arm 46 is connected by a connecting rod 55. The connection of the connecting rod 55 to the first and second arms 45 and 46 is possible by welding or bolting.

The first arm 45 and the second arm 46 are pivoted simultaneously from both sides with the cover 13 interposed therebetween and the cover 13 is lifted or retracted by the first and second openings 13a and 13b, It is possible to perform a more accurate durability test because it maintains the horizontal state in the width direction without being inclined to either side in the width direction.

The controller 51 is installed under the table 33 to control the operation of the actuator 35 and to check the operation characteristics of the actuator in real time through various sensors (not shown) installed in the actuator. The number of repeated opening / closing operations of the cover, the operation speed of the actuator, and the like are built in the controller 51, and can be output later.

The output unit 53 is connected to the controller 51 and indicates the number of times the cover 13 is repeatedly opened and closed, the current operation speed of the actuator, and the like.

5 is a side view schematically showing the durability test of the cover using the test apparatus shown in FIG.

As shown in the figure, in a state in which the actuating rod 35b of the actuator 35 is fully drawn out (in this state, the first and second arms 45 and 46 are horizontally positioned and the cover 13 is also horizontally As the pinion gear 39 is pulled in the direction of the arrow f, the pinion gear 39 rotates in the direction of the arrow a, and the first and second arms 45 and 46 rotate in the direction of the arrow b.

As described above, since the center of rotation of the rotary shaft 39a is located between the folding lines x2 and x1, when the first and second arms 45 and 46 rotate in the direction of arrow b, 2 opening portion 13b. In this state, when the rack gear 37 is moved in the opposite direction, the first and second arms 45 and 46 rotate in the direction opposite to the direction of arrow b, and the cover 13 is unfolded again.

As a result, by controlling the operation of the actuator 35 through the controller 51, the cover 13 can be repeatedly folded and folded to test the durability of the cover 13. The number of cumulative tests of the current cover and the like are displayed through the output unit 53 during the repetitive test.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

Since the durability test of the cover for covering the luggage trays can be sufficiently performed, the durability of the produced cover can be accurately grasped and reflected in the product design, Thereby improving the performance of the system.
