Description

Lock mechanism for glove box

Technical Field

The invention belongs to the field of automobile parts, and particularly relates to a lock mechanism for a glove box.

Background

With the improvement of living standard and the increase of economic income of people, the household vehicle is more and more popular. In the automobile structure, the storage box that can open that is located front passenger seat is the glove box, and the glove box space is not big, can be used to place some little articles commonly used, and the practicality is very strong. The glove box door plate is fixed on the structure of the front part of the automobile by the glove box lock, and the door plate can be conveniently opened by loosening the wrench on the door plate by hand when the glove box lock is needed.

At present, in a lock mechanism of a common glove box, a lock tongue is separated from a lock piece by turning a handle, and the glove box is opened, so that the structure is simple. However, in the structure, the glove box is easy to have a virtual buckle phenomenon in the closing operation, and when the virtual buckle is buckled, the bolt is contacted with the locking piece, but the bolt does not completely enter the locking piece to be locked. Under the condition, when the automobile shakes and jolts, the door panel falls off to be in an open state, which is troublesome and even causes accidents.

Therefore, in order to solve the above problems, the present invention provides a glove box lock structure in the prior art, which is further researched and improved, and can eliminate the phenomenon of false buckling through simple structural improvement.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the lock mechanism for the glove box, which is simple in structure, low in cost and capable of well avoiding the phenomenon of virtual buckling through the arrangement of the elastic sheets.

In order to solve the above technical problems, the present invention is solved by the following technical solutions.

A latch mechanism for a glove box comprises a handle assembly and a support assembly which are arranged on a door plate of the glove box, wherein the handle assembly and the support assembly rotate relatively; the glove box is characterized in that a lock tongue mounting seat is arranged in the support assembly, a lock tongue is arranged in the lock tongue mounting seat, the lower end of the lock tongue is abutted to a spring arranged in the lock tongue mounting seat, the upper end of the lock tongue is matched with a lock piece in the glove box, and the lock tongue is pressed down by a pressing plate on the handle assembly when the handle assembly rotates.

Among the prior art, the phenomenon of virtual knot is produced easily with the latch fitting to the spring bolt on the glove box, in this application, through setting up this phenomenon of fine elimination of shell fragment. When closing, the shell fragment offsets with the latch fitting, produces to interfere the latch fitting and breaks the state that spring bolt and latch fitting virtual were buckled, and the user can discover to lock at this moment, can reuse power to close the door plant and go up the position to locking.

Preferably, a cavity is formed in one side, facing the handle assembly, of the lock tongue, and the pressure plate extends into the cavity and abuts against a bottom plate of the cavity. This compact structure rotates the handle subassembly when opening the door plant, makes the clamp plate down press the spring bolt, makes spring bolt and latch fitting contact locking, reaches the purpose of opening the door.

Preferably, the pressing plate is covered with a cushion layer, such as a cloth layer or a non-woven fabric layer, to reduce noise generated by touch.

Preferably, the spring plate is provided with a bolt hole for fixing.

Preferably, both ends of the bracket component are provided with rotating shafts extending outwards, both sides of the handle component are provided with side plates, and the side plates are provided with rotating shaft holes matched with the rotating shafts. In the structure, the relative rotation of the bracket component and the handle component is realized after the rotating shaft and the rotating shaft hole are assembled together.

Compared with the prior art, the invention has the following beneficial effects: the utility model provides a latch mechanism for glove box, through the fine phenomenon of virtual knot of having avoided of setting up of shell fragment, simple structure, it is with low costs.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 6, the latch mechanism for the glove box, which is disclosed by the invention, comprises a handle assembly 1 and a support assembly 3 which are arranged on a door panel 2 of the glove box, wherein the handle assembly 1 and the support assembly 3 rotate relatively, a pressure plate 11 is arranged on the handle assembly 1, a spring plate mounting seat 14 is arranged on the pressure plate 11, a spring plate 4 is arranged in the spring plate mounting seat 14, and a bolt hole 41 is arranged on the spring plate 4; the glove box is characterized in that a bolt mounting seat 71 is arranged in the bracket component 3, a bolt 6 is arranged in the bolt mounting seat 71, the lower end of the bolt 6 abuts against a spring 7 arranged in the bolt mounting seat 71, the upper end of the bolt 6 is matched with a locking piece 37 in the glove box, and the bolt 6 is pressed down by a pressing plate 11 on the handle component 1 when the handle component 1 rotates.

In this embodiment, as shown in fig. 2, one side of the latch bolt 6 facing the handle assembly 1 is provided with a cavity 62, the pressing plate 11 extends into the cavity 62 and abuts against the cavity bottom plate 61, the pressing plate 11 is covered with the cushion layer 5, the structure is compact, the handle assembly 1 is rotated when the door panel is opened, the pressing plate 11 presses the latch bolt 6 downwards, the latch bolt 6 is locked by contacting with the locking piece 37, and the purpose of opening the door is achieved.

In addition, in this application, the both ends of bracket component 3 are equipped with the pivot 31 that outwards stretches out, the both sides of handle subassembly 1 are equipped with curb plate 13, are equipped with the pivot hole that matches with pivot 31 on this curb plate 13, realize bracket component 3 and handle subassembly 1's relative rotation after pivot 31 and the assembly of pivot hole together.

Fig. 4 to 6 show the schematic diagram of the latch mechanism under different states, and in fig. 4, the glove box door panel 2 is in the closed state, and the spring bolt 6 enters into the latch fitting 37 and is in the dead state of buckling this moment, and spring 7 jacks up the spring bolt 6, and the upper end of shell fragment 4 offsets with the tip of latch fitting 37, and is overall stable, and shell fragment 4 produces the interference thrust, makes the latch fitting 37 difficult deviate from. In fig. 5, the schematic diagram in the virtual buckle state is an unstable state, and it can be seen from the diagram that the top of the lock tongue 6 abuts against the lower edge of the end of the lock piece 37, but does not enter the dead lock area, and will spring open with a slight shock, so that the elastic piece 4 in this application abuts against the end of the lock piece 37 to generate a thrust, which destroys the virtual buckle state, so that the lock tongue 6 cannot buckle, and the user closes the door again. In fig. 6, in the state of lacking the elastic sheet 4, the top of the latch 6 abuts against the lower edge of the end of the locking piece 37 to be in a virtual buckling state, and in this state, when the automobile shakes and bumps, the door panel falls off to be in an open state, which is troublesome and even causes accidents.

Above, among the prior art, the phenomenon of virtual knot is produced easily with the latch fitting to the spring bolt on the glove box, in this application, through this phenomenon of fine elimination of setting up of shell fragment 4. When closing, shell fragment 4 offsets with latch fitting 37, produces to interfere to latch fitting 37 and breaks the state that spring bolt 6 and latch fitting 37 were detained in vain, and the user can discover to lock at this moment, can put down the door plant with strength again and go up the position to locking. Low cost and good effect.

The scope of the present invention includes, but is not limited to, the above embodiments, and the present invention is defined by the appended claims, and any alterations, modifications, and improvements that may occur to those skilled in the art are all within the scope of the present invention.
