Description

Lock-assembly for armrest box of automobile}

The present invention relates to a lock-assembly of the storage unit cover built in the armrest installed in the rear seat of a passenger vehicle, that is, a fixing device, and easy operation through an opening button in opening and closing the cover of the storage unit formed inside the armrest. At the same time, the lock assembly of the cover composed of an open button, a fixed hook, and the like is composed of a link structure in which rotation and linear motion are combined, thereby improving operation efficiency and durability.

A rear seat armrest is installed in the center of the rear seat of the passenger car to allow the passenger to take a more comfortable posture.The armrest includes a storage unit for storing the belongings of the passenger or an air conditioner and a console for operating audio. It is common for convenience devices to be constructed.

A cover installed in the armrest is generally installed with a hinge connected to the hinge (Hinge), a lock is configured between the cover and the main body of the housing, and the cover is opened and closed by a user operating the cover.

The locking device is configured to control the locking state of the main body and the lid, that is, the lid is fixed to the housing in a closed state, and the housing can be opened by releasing the fixed state according to the user's operation. Operation means such as a button is installed on the front side of the cover to facilitate operation while the arm is in an extended state, and the lock state of the cover is secured while the fixing hook installed at the lower part of the cover is separated from the locking jaw at the upper end of the cover according to the user's operation. It is released and the opening of a housing is enabled.

In this locking device, the operation direction of the opening button is the linear movement in the front and rear, that is, the horizontal direction, whereas the ultimate movement of the fixed hook is a rotational movement for deviating from the locking jaw, so that a fixed rotating shaft is usually installed inside the fixed hook. And the upper part of the fixed hook is rotated as the opening button is operated to achieve the desired rotational movement, there was a lot of restrictions in connecting the upper part and the opening button of the fixed hook.

That is, in order to rotate the upper end of the fixed hook, it is impossible to fix the upper end of the fixed hook and the open button in any form when the opening button is in a completely straight motion, and the open button is operated by sliding on the upper end of the fixed hook. It can only be configured.

On the other hand, in the case of connecting the upper end of the opening button and the fixed hook by the hinge, the opening button is bound to the circular motion (후크) like the hook.

Therefore, in the conventional armrest storage part cover fixing method, there is a limit in terms of durability, ease of operation, and miniaturization in configuring the locking device.

The present invention was conceived in view of the above-mentioned problems, and in connecting the open button and the fixed hook, by connecting each of them in a link structure of a combination of rotation and linear motion, the complete linear motion of the open button and the smooth rotation of the fixed hook This is to be achieved at the same time.

The operation of the opening button and the fixed hook is a hook shaft groove and a cross rod hole formed on the side wall behind the opening button, and the hook shaft hole and a cross rod groove formed on the top of the fixed hook are connected by the hook shaft and the cross rod, respectively, The shaft is moved along the transverse rod groove formed in the fixed hook, and the shaft coupled to the fixed hook is made possible by moving along the hook shaft groove formed in the opening button.

The detailed configuration and operation principle of the present invention will be described with reference to the accompanying drawings.

First, Figure 1 shows the armrest 10 to which the present invention is applied, is installed in the center of the rear seat so that the occupant of the rear seat of the passenger car can take a comfortable posture, it may be configured to be stored in the back of the back seat as needed.

FIG. 2 is a cross-sectional view of the housing 20 in an open state in FIG. 1, and one end of the housing 20 and the cover 21 are connected to each other by a hinge, and the other end of the cover 21 is the same. As can be seen in the enlarged part of the garden, a lock-assembly consisting of a fixed hook 34 or the like is installed, and the fixed hook 34 is coupled to the engaging jaw 22 of the housing 20. It can be seen that the lock state of the cover 21 is fixed and released as it is separated.

Here, the fixing hook 34 is rotated by operating the opening button 32 installed in front of the cover 21, the detailed coupling relationship and operation principle of these fixing hook 34 and the opening button 32 as follows. same.

3 is an excerpt perspective view of the lock assembly (lock-assembly) of the present invention, that is, the open button 32 and the fixed hook 34, etc. are combined, and FIG. 4 is a semi-transparent view of FIG. Pressing the opening button 32 coupled to the hook, the hook hook (41) is rotated in the counterclockwise direction on the drawing in the shaft, and when the external force is removed by the built-in spring (50) Will be restored.

5 is an exploded perspective view clearly showing the coupling relationship between the components of the present invention, the opening button 32 having a pair of side walls 33 formed in the rear reciprocating longitudinally, that is, horizontal direction to the button housing 31 It is coupled as possible, and the fixing hook 34 is coupled between the pair of side walls (33).

On the other hand, both sidewalls 33 of the open button 32, the hook shaft groove 35 and the cross rod hole 36 is formed in the upper and lower, respectively, and the hook shaft hole 37 in the upper and center portions of the fixed hook 34, respectively And a cross rod groove 38 and a hook shaft 41 and a cross rod hole 36 and a cross rod groove which penetrate the hook shaft groove 35 and the hook shaft hole 37 and are fixed to the button housing 31. It is connected by a cross bar 42 penetrating through 38, and has a link structure in which a hinge and a roller are mechanically combined.

Therefore, when the opening button 32 is moved horizontally, the fixing hook 34 is rotated to the axis of the hook shaft 41, the position of which is fixed to the button housing 31, coupled to the opening button 32 The cross bar 42 is moved along the cross bar groove 38 of the fixed hook (34).

This, the operation of the fixed hook 34 of the present invention is shown as a schematic diagram for each operation step in Figure 6, thereby achieving efficient rotation of the fixed hook 34 in the state that each operating body is firmly coupled in the minimum operating space. Will be.

As a result, the technical gist of the present invention is a lock-assembly installed at the cover 21 of the housing 20 embedded in the armrest 10 for automobiles and fixing it, and a pair of side walls 33 at the rear side. The open button 32 is formed is coupled to the horizontal reciprocating in the button housing 31, the fixing hook 34 is fastened to the engaging jaw 22 formed in the receiving portion 20 in the armrest 10 A hook shaft groove 35 and a cross rod hole 36 are provided between the sidewalls 33, and the upper and lower sides of the sidewalls 33 of the open button 32 are elongated horizontally with the moving direction of the open button 32, respectively. ) Is formed, and the hook shaft hole 37 and the cross bar groove 38 are formed in the upper and center portions of the fixed hook 34, respectively, the hook shaft 41 coupled to the hook shaft groove 35 and the hook shaft hole 37. The button housing 31 is installed to be coupled to, the cross bar hole 36 and the cross bar groove 38, the cross bar 42 is coupled, the opening button 32 is forward and backward As the fixed hook 34 rotates the hook shaft 41 to the axis and ascends and retracts along the trajectory coinciding with the cross bar groove 38, the lower portion thereof is fastened and detached from the locking jaw 22. It is a lock assembly for a car armrest storage part.

Through the present invention, the locking device of the armrest storage unit for a passenger car can be manufactured more firmly and compactly, thereby securing the competitiveness of the related automobile industry and improving the customer's satisfaction.
