Description

Pop-up device

The present invention relates to a pop-up mechanism, and more particularly, to a pop-up mechanism for raising or lowering the arm rest installed in the center console box or the rear console box of a vehicle.

In general, a console box with a space inside is provided between the driver's seat and the passenger seat for storing small items, and the upper part of the console box opens and closes the space, and in general, an armrest that the driver can put his arm on is provided. It is installed.

The armrest at this time serves to assist the driver to drive in a comfortable position.

Since the armrest of such a console box is designed with the height and size corresponding to the most standard in automobile production, it cannot cope with all the various body structures of the driver, and this causes inconvenience to some drivers because the height and position of the armrest are not correct. Can cause.

In order to solve this problem, recently, a technique of installing a popup mechanism that moves up and down by button operation on an arm rest of a console box and appropriately raising the height of the arm rest has been proposed.

The conventional pop-up mechanism, as shown in Figures 6 and 7, the airway member (110a), 110b, which is spaced at a predetermined interval on the cover 100 of the console box as a gas, the airway (起) Iv) attachably attachable, and connect the armrest 120 to the upper end of the airway members 110a and 11b to be rotatable to form a link mechanism, and cover the airway members 110a and 110b. A torsion spring 130 is installed at the connection portion 100 to support the airway members 110a and 110b in an upright direction, and also maintain the standing or doppled state of the airway members 110a and 110b. To this end, the lock piece 140 and the hook 150 are formed on the armrest 120 and the cover 100, respectively.

Accordingly, in the case of using the armrest 120, by pressing the front button 160 to release the hook 150, the airway members 110a, 110b stand up by the force of the torsion spring 130. By rotating in the direction, the armrest 120 is raised and the lock piece 140 is locked to the one airway member 110b side with this, so that the popup state of the armrest 120 is fixed.

On the contrary, when the armrest 120 is not in use, lightly pressing the upper surface of the armrest 120 downward while the locking piece 140 is released by the operation of the button 160, the airway member 110a, At the same time as the 110b is folded, the armrest 120 is caught by the hook 150, so that the armrest 120 can be returned to the folded state.

However, the conventional pop-up mechanism as described above has a large number of components and is not only complicated in structure, but is also configured to support the load by the airway member, so that the airway member, the cover, the airway member, and the armrest can withstand the load. A metal shaft must be used for the connecting shaft to connect, which causes a reduction in weight, causes an increase in cost, complexity of assembly work, and the like.

In addition, since the load is supported by the airway member in a vertically standing state, a large force may be applied in the direction in which the airway member is rotated, depending on the direction of the load. In the state, a large load is applied to the locking part, and the related parts, in particular, a lock piece that is caught by the concave structure has a disadvantage of being easily broken.

Accordingly, the present invention has been made in view of the above, and a stable supporting structure exhibited by a block-type moving block in a pop-up state and a locking mechanism of lock locking the moving block in a surface contact manner while interlocking with a button By implementing a new type of pop-up system to include, it is possible to simplify the overall structure, and in particular, to provide a pop-up mechanism that can be reduced in weight, cost reduction, and assembly workability by securing a stable support structure and a rigid locking structure. The purpose is.

In order to achieve the above object, the pop-up mechanism provided in the present invention includes a lower plate installed on the cover side of the console box, a pair of front and rear moving blocks connected to the upper surface of the lower plate so as to be rotatable, and the armrest side and are movable. An upper plate that is rotatably installed on the upper end of the block, a spring that elastically supports the moving block in one direction, and a button that is installed to move back and forth along the upper plate and is held in a hook on the lower plate to maintain a folded state. And, interlocked with the button and installed on the upper plate to move up and down structure and includes a lock for maintaining a pop-up state while walking the rear surface of the upper end of the moving block in the form of a contact surface facing the direction of rotation of the moving block. It features.

Here, the lock is preferably supported so as to be sandwiched around the button to move up and down by contact with the inclined surface on the button.

In addition, the upper plate preferably further comprises a guide for guiding the up and down movement of the lock while contacting one side of the lock.

The popup mechanism provided by the present invention has the following advantages.

First, in the pop-up state, the moving block made of the left and right integral blocks can support the load in a solid posture, so that the pop-up state can be stably maintained even when a large force is applied in the direction of rotating the moving block according to the direction of the load. .

Second, in the case of the lock for locking and releasing the pop-up state, the moving block can be hung or released by the surface contact method while operating up and down in conjunction with the button. Concerns such as being completely eliminated.

As a result, the above points can simplify the overall structure of the pop-up mechanism, and can increase the selection and design freedom of the components constituting the pop-up mechanism. Therefore, it is possible to reduce the weight, reduce the cost, and improve the assembly workability. You can expect the effect.

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

1 and 2 are perspective views showing a folded state and a pop-up state of the pop-up mechanism according to an embodiment of the present invention.

As shown in Figure 1 and 2, the pop-up mechanism is assembled between the cover of the console box and the armrest installed on the upper portion of the cover, the lower plate 10 fixed to the cover side, and the lower A pair of front and rear moving blocks 11a and 11b rotatably attached to the plate 10 and an upper plate rotatably connected to upper ends of the moving blocks 11a and 11b and to which the armrest is attached. (12) and the like.

The lower plate 10 is formed of a substantially flat substrate, and four shaft holders 19a, one hook 14, and two block receiving portions 20 are formed on an upper surface of the substrate.

In this case, the shaft holder 19a is formed to protrude from the substrate, and is located at four corners of the substrate, and is a portion capable of fitting the pins 22, which are pivoting center axes of the moving blocks 11a and 11b.

In addition, the hook 14 has a hooked end portion, and is a portion for hooking the button 15 assembled to the upper plate 10.

In addition, the block receiving portion 20 is a portion for receiving the moving blocks (11a, 11b) to collapse in a folded state, and serves to lower the overall height of the pop-up mechanism when folded.

The moving block 11a positioned at the front of the pair of moving blocks 11a and 11b is a front moving block connecting the front end of the lower plate 10 and the front end of the upper plate 12 and positioned at the rear side. The moving block 11b is a rear moving block connecting the rear end of the lower plate 10 and the rear end of the upper plate 12.

The moving blocks 11a and 11b are formed of a substantially rectangular block body, and a pair of protrusion pieces 21 are formed at both upper and lower ends of the block body, and the protrusion pieces 21 at this time are the lower plate ( The pins 22 are horizontally coupled together in a state in which they are located in the shaft holder 19a in 10 and the shaft holder 19b of the upper plate 12 described later, so that the moving blocks 11a and 11b The link structure is complete.

In addition, a spring 13, for example, a torsion spring is attached to the pin coupling portion of the lower plate 10 side of the moving blocks 11a and 11b, and the torsion springs move the moving blocks 11a and 11b. ) Can always have the power to rotate forward.

The upper plate 12 is formed of a substantially flat substrate, and four shaft holders 19b positioned at four corners are formed on the lower surface of the substrate, whereby the moving blocks 11a and 11b are formed. Combined into a pin structure.

In addition, the upper plate 12 has a slide groove portion 23 extending along the middle line of the width to accommodate the button 15 is formed, whereby the button 15 is guided in the slide groove portion 23 Can be moved back and forth.

The button 15 is a part which the user manipulates by hand, has a long bar shape, and is integrally installed in the slide groove 23 of the upper plate 12 in a slidable structure.

Here, the button 15 is elastically supported by a spring (not shown) of the rear end, and thus has a property of always moving forward in a state where no external force is applied.

Of course, although not shown in the drawings, after the button is drawn to some extent by the force of the spring, the locking state for preventing the removal may be maintained.

In addition, the button 15 has a hole 24 is formed in the middle of approximately the length can be caught with the hook 14 of the lower plate 10 through this.

That is, since the hook 14 penetrates the hole 24 and is caught on the upper surface around the hole, the folded state of the entire armrest including the button 15 and the upper plate 12 can be maintained.

In addition, the upper surface of the button 15 is formed with an inclined surface 17 inclined downward from the front to the rear, the inclined surface 17 at this time to move the lock 16 to be described later through the contact up and down Play a role.

In particular, the present invention provides a lock 16 to maintain a stable and solid pop-up state even when a high load according to the load is applied.

To this end, the lock 16 is formed in the shape of a rectangular plate with a substantially empty center, and is positioned in the slide groove 23 in the upper plate 12 in the width direction while being fitted around the button 15. That is, the button 15 is installed in the form of penetrating the empty part of the lock 16.

Accordingly, the lock 16 can be moved in the form of being lifted up or down by its own weight in contact with the inclined surface 17 when the button 15 is moved back and forth.

In addition, since the lock 16 can be guided while its one side is in contact with the guide portion 18 formed on the upper plate 12, the lock 16 can be accurately operated.

The lock 16 installed as described above can be moved up and down while contacting the inner wall surface of the slide groove 23, and in the lowered position, the upper side of the upper portion of the moving block 11a is opposed to the rotational direction of the moving block 11a. You can walk in the form of surface contact.

Thus, one side of the lock 16 and one side of the moving block 11a are formed in a face-to-face contact manner so that the locking structure of the structure in which the moving block 11a is engaged with the direction to rotate for the folded state is achieved. As a result, even when a large load is applied to the lock 16 side, a locked state for maintaining a stable pop-up state can be secured without fear of damage.

Therefore, looking at the operating state of the pop-up mechanism of the present invention configured as described above are as follows.

3 and 4 are side views showing the folded state and the pop-up state of the pop-up mechanism according to an embodiment of the present invention.

The pop-up mechanism is assembled between the cover of the console box and the arm rest installed thereon.

That is, by fixing the lower plate 10 on the cover and attaching the armrest on the upper plate 12 is assembled between the cover and the armrest.

In addition, as shown in FIG. 3, the hook 14 of the button 15 is in a folded state in which the moving blocks 11a and 11b fall down on the lower plate 10 against the elastic force of the torsion spring. It is locked by being engaged with the hole 24.

In this state, when using the armrest by raising the upper plate 12, first, the button 15 is pressed.

In this way, the button 15 slides backward, and at the same time, the locking state is released while the hook 14 held at one side of the hole 24 of the button 15 is released.

Accordingly, the moving blocks 11a and 11b are rotated to the front side by the force of the spring 13, so that the entire upper plate 12 including the armrest is raised by the action of the link mechanism and is moved forward. To the side.

Then, when the moving blocks 11a and 11b are rotated to a predetermined angle, the bottom surface of the block touches the upper surface of the lower plate 10 so that the rotation of the moving blocks 11a and 11b is stopped. It becomes a popup state as shown in 4.

At this time, as shown in Fig. 5, the lock 16, which is lowered from the button 15 side, hangs the rear of the upper end of the front moving block 11a, so that the pop-up state is fixed.

In this way, when the upper plate 12 is popped up and used as an armrest, in the pop-up mechanism of the present embodiment, most of the loads on the upper plate 12 in the popped-up state are in contact with each other. Since it is supported by the lower end surface of the block body and the upper surface of the lower plate 10, no heavy load is applied to both the moving blocks 11a, 11b and the locking portion of the lock 16. Even when a load is applied in the direction in which the 11 and 11b are to be folded, the lock 16 and the moving block 11a are hung in a surface contact manner so that the lock and the like are not damaged.

In addition, when lowering the upper plate 12 in the pop-up state shown in FIG. 4 to return to the folded state of FIG. 3, by pressing the button 15, as shown in FIG. And the locking state in the pop-up state is released while the locking state between the moving block 11a and the moving block 11a is released.

In this state, the armrest is slightly pushed to the rear and slightly pressed downward to move the moving blocks 11a and 11b to the rear side and at the same time, the upper plate 12 including the armrest is lowered, and together with the upper plate ( Since the hook 14 in 12) is caught in the hole edge after entering the hole 24 of the button 15, the folded state is fixed.

On the other hand, the pop-up mechanism of the present invention is employed as a lifting device of the arm rest formed on the console box of the vehicle as in the above embodiment, but the use of the pop-up mechanism of the present invention is not limited to this, and various It is possible to use it as a mechanism for changing the relative positional relationship with the need to change the relative positional relationship between the lower plate and the parts attached to the lower plate according to the armrest of the chair and the state of use.
