Detailed Description

The invention will be further described with reference to the following examples.

The utility model discloses a two locking mechanical system's of handrail case that open door of car embodiment, as shown in fig. 1 to 5, including button 2, spring bolt 3, base 1 and rotatable clutch 4. Base 1 is the setting of L type, and install in the top of base 1 spring bolt 3 slidable, specifically can be through setting up the sand grip in the both sides of spring bolt 3, makes to form the sliding tray between two sand grips. Button 2 slidable ground is installed in the below of base 1, specifically can realize through the mode of pegging graft, and button 2 is equipped with the dog that extends up, the dog orientation base 1 extends fixed column 22, and base 1 sets up the through-hole that supplies fixed column 22 to wear out, just so can realize fixed mounting promptly and also can realize the slip of button 2. Referring to fig. 2, a rotating shaft 5 is disposed in the middle of the clutch member 4, two end portions of the rotating shaft 5 are fixedly mounted on the base 1, and the clutch member 4 can rotate relative to the rotating shaft 5.

As an improvement, please refer to fig. 2 to 5, a first swing arm 41 and a second swing arm 42 are formed at the outer peripheral side of the clutch 4 and are arranged at intervals along the circumferential direction of the clutch 4, and in a most preferable scheme, an included angle between the first swing arm 41 and the second swing arm 42 is greater than 90 degrees, the greater the included angle between the two swing arms is, the smaller the force required for unlocking is, and the faster the unlocking amplitude or speed is. The first swing arm 41 and the second swing arm 42 of the clutch 4 are arranged along the circumferential direction of the clutch 4, and are matched with the layered structure of the lock tongue 3 and the button 2, so that the structure is compact, the mechanical strength is high, the occupied space is small, and the excessive space area of the armrest box can not be occupied.

In the present embodiment, referring to fig. 2 to 5, the end of the push button 2 near the clutch 4 abuts against the first swing arm 41. Specifically, in order to save the installation space and to have a sufficient swing range when pushing the first swing arm 41, the end of the button 2 close to the clutch member 4 extends obliquely downward to the push arm 21 to abut against the first swing arm 41, and in this embodiment, the push arm 21 is arranged obliquely downward in a step shape, but of course, the button can also be in other shapes such as an inclined surface. In order to make the structure more compact, a slot 411 for inserting the push arm 21 is formed on the surface of the first swing arm 41 close to the push arm 21.

Referring to fig. 3, in the present embodiment, the second swing arm 42 abuts against the latch bolt 3, in order to make the structure more compact, a groove 31 is formed on the bottom surface of the latch bolt 3, and the end of the second swing arm 42 is inserted into the groove 31.

Referring to fig. 5, in order to enable the button 2 and the clutch member 4 to automatically return after the locking mechanism is unlocked, an elastic return member for driving the latch 3 to move in the upward locking direction is disposed between the base 1 and the latch 3, and preferably, the elastic return member is a return spring 81. The fixing post 22 is sleeved with a limiting spring 82 which abuts against the base 1.

Referring to fig. 4-5, when unlocking, an external horizontal pressing is applied to the button 2, the button 2 horizontally moves to abut against the first swing arm 41 to drive the first swing arm 41 to rotate, and the limiting spring 82 is in a compressed state after the button 2 horizontally moves. When the first rotating arm 41 rotates, the clutch part 4 and the second rotating arm 42 can be driven to rotate at the same time, the second rotating arm 42 abuts against the groove wall of the groove 31 of the bolt 3, the second rotating arm 42 rotates to drive the bolt 3 to move in the direction opposite to the horizontal movement of the button 2, after the bolt 3 moves, the reset spring 81 is in a compression state, the bolt 3 is enabled to be separated from a lock hole of an external box cover, and the box cover is opened by a torsional spring of the box cover, so that unlocking is achieved. When the external force applied to the button 2 is released, the compressed return spring 81 drives the latch bolt 3 to return, and the limit spring 82 also drives the button 2 to return, so that the locking mechanism is in a locked state. It should be noted that the limiting spring 82 is arranged to reduce the load of the return spring 81, so as to avoid the need for the return spring 81 to return the latch 3 and the button 2, thereby prolonging the service life of the locking mechanism.

When the box cover is completely closed, the reset spring 81 can drive the end part of the bolt 3 to be inserted into the lock hole of the box cover, so that locking is realized. It should be noted that, because button 2 and spring bolt 3 carry out the linkage through clutch 4 to, the direction of motion of button 2 and spring bolt 3 is opposite during the unblock, consequently, the case lid supports the in-process that locks the removal of spring bolt 3, no matter whether button 2 is in the state of pressing or button 2 has foreign matter or foreign matter to block and can't remove, can not influence the motion of locking of spring bolt 3, consequently, can smoothly close the case lid, the structure is ingenious practical.

Compared with the prior art, through adopting the mode of horizontal direction operation unblock to come the unblock handrail case, improve the operation and feel, promote user and use experience, simple structure, it is easy and simple to handle, more be fit for the driver and open the handrail case, and clutch 4 turns into the level removal to the right with the level removal left, and more laborsaving when clutch 4's setting can make the unblock.

It should be noted that the above locking mechanism is suitable for a side-opening single-door armrest box, and in order to be suitable for a double-door armrest box, in this embodiment, two lock tongues 3 are provided, two lock tongues 3 are arranged at intervals, two second swing arms 42 of the clutch member 4 are also provided, and the two second swing arms 42 respectively abut against one lock tongue 3. To facilitate the preparation and assembly of clutch 4, a first swing arm 41 is located in the middle of clutch 4, and first swing arm 41 is located between two second swing arms 42. Through the second swing arms 42 arranged at intervals, the button 2 can synchronously open the two box covers during unlocking, so that the opening process of the armrest box is smoother.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
