Description
Technical Field
The invention relates to an automobile seat lock structure, in particular to a two-gear seat lock for an automobile, and belongs to the technical field of automobile lock structures.
Background
ZL200710002704.2 discloses a car seat lock, comprising: a striker fixed to the vehicle body and including a first engagement portion and a second engagement portion, a first base member fixed in the seat back, a second base member connected to the first base member and fixed in the seat back, a first pivot fixed to the first and second base members between the first and second base members, a first spring wound on the first pivot, a hook member pivotally fixed on the first pivot against a force of the first spring wound around the first pivot, and including a first arm, a second arm and a pivot portion, a first engagement groove formed between the first arm and the second arm, a second engagement groove formed between the second arm and the pivot portion, a buffer portion formed on a rear edge of the pivot portion facing the second engagement groove, the buffer portion being molded of resin, the striker engaging the first engagement portion in the hook member when the first engagement portion enters the hook member engagement groove, the first arm engages the first seat back, the buffer portion engaging the first seat back in the first engagement groove, and the striker engaging the first seat back in the first engagement groove if the first engagement portion is engaged by the first engagement groove, and the striker is engaged by the second engagement groove.
However, in the saddle lock, because the whole bottom of the clamping groove of the clamping plate for one gear is a transition arc section, when the lock pin is impacted downwards to pass through the arc section, the impact force requirement on the lock pin is strict, and the impact force is insufficient, so that the locking operation cannot be completed; and once the impact force is too large, the lock pin is very easy to slide to the second gear along the transition arc section of the first gear clamping groove, so that the operation of the second gear lock is disabled. Meanwhile, the first pivot plays a role of connecting the first base component and the second mechanism component, and simultaneously provides pivoting for the hook component and the first spring, the fixing of the integral lock and the seat backrest is realized through the mounting holes on the first base component and the second base component, and when the seat lock is locked, the outward opening acting force of the lock pin does not pass through the fixing mounting points of the seat lock and the backrest, but acts on the mounting holes of the first base component and the second base component, so that adverse effects are easily caused on the lock body component for a long time, and the integral lock strength is lower. Secondly, carry out amortization through moulding the whole package of cardboard in the above-mentioned lock body, in the in-service use, can take place package plastic layer wearing and tearing and drop, consequently lead to amortization inefficacy problem.
Disclosure of Invention
The invention aims to solve the problems that the force applied by the existing two-gear locking lock pin is difficult to control, the locking cannot be completed due to too small force, and the lock pin with too large force directly rushes through a first gear to enter a second gear; the second aim is to solve the problem of low integral locking strength of the existing two-gear seat lock; thirdly, the locking buffer is insufficient and the noise is large; the invention solves the three main problems one by one through structural adjustment, and provides the two-gear seat lock for the automobile, which has the advantages of structural optimization, high integral locking strength, stable and reliable locking operation and good silencing effect.
In order to solve the problems, the invention adopts the following technical scheme:
the two-gear seat lock for the automobile comprises a lock body, and a clamping plate 2 and an opening arm 3 which are respectively arranged in the lock body in a pivoting manner and mutually matched to realize locking/unlocking, and is characterized in that a first locking clamping groove 2-1 and a second locking clamping groove 2-2 which are respectively matched with a lock pin 7 to realize two-gear locking are arranged on the clamping plate 2, and a straight line section 2-1a corresponding to the falling position of the lock pin 7 is arranged at the bottom of the first locking clamping groove 2-1; compared with the original arc section, the straight section 2-1a has the function of resisting the impact force of the lock pin and preventing the lock pin from directly punching into the second gear locking position. When the lock pin 7 impacts downwards, the lock pin 7 pushes the clamping plate to rotate and move downwards to the straight line section 2-1a beyond the clamping plate head, and the straight line section 2-1a counteracts a certain impact force and blocks the lock pin on the straight line section.
The lock body comprises a base plate 1 and a cover plate 6 for providing mounting support, wherein the base plate 1 is provided with a shaft hole 1-1 corresponding to the mounting hole of the clamping plate 2, and a clamping plate shaft sleeve 10 penetrates through a clamping plate torsion spring 9 and the clamping plate mounting hole and is then fixed on the shaft hole of the base plate 1; the lock body mounting bolt penetrates through the hollow structure 10-1 of the clamping plate shaft sleeve 10 to fix the whole lock on the seat backrest; the clamping plate shaft sleeve 10 provides a pivot center for the clamping plate 2 and simultaneously serves as a whole lock mounting hole, so that the fixing effect of the original whole lock mounting hole is replaced by the structural change, and the outward opening acting force of the lock pin is transmitted to the lock body mounting bolt through the clamping plate shaft sleeve; the original lock body structure is simplified, and meanwhile, the whole lock strength is optimized.
In order to reduce noise caused by the impact of the lock pin, one of the schemes adopted by the invention is that a buffer block is arranged at the locking port part of the base plate 1 or the cover plate 6; another alternative is to design a non-metallic over-molding layer on the locking pin.
The clamp plate 2 and the opening arm 3 are both arranged in the lock body in a pivoting manner, wherein the clamp plate 2 and the clamp plate torsion spring 9 are arranged in a pivoting manner through the clamp plate shaft sleeve 10, the opening arm 3 and the opening arm torsion spring 8 are arranged on one side of the clamp plate 2 through the opening arm shaft 4, the opening arm 3 is controlled by an external opening device, and the opening arm 3 pushes the clamp plate opening shaft 5 arranged on the clamp plate 2 in the rotating process of the opening arm 3 so as to drive the clamp plate 2 to rotate through the clamp plate opening shaft 5.
The substrate is provided with a turning riveting structure, and the cover plate and the substrate can be further fixedly connected by using a turning riveting process.
According to the two-gear seat lock for the automobile, the cambered surface structure at the bottom of the first-gear locking groove of the original clamping plate is changed into the planar structure, so that the locking pin is effectively blocked by the planar structure when falling into the lock, and cannot slide down to the second-gear locking position directly, and the operability and stability of locking are improved; the shaft sleeve structure capable of fixing the whole lock on the vehicle body replaces the original riveting shaft, so that the riveting shaft which only provides the pivot center of the clamping plate originally has the function of installing the whole lock, and the outward opening acting force of the lock pin is effectively transferred from the lock body to the vehicle body installation bolt, thereby greatly improving the strength and the service life of the whole lock. In addition, in order to solve the problem that cardboard package plastic abrasion amortization inequality, change cardboard are with high costs, this application provides removable buffer block, installs the buffer block on base plate or apron, can play the same buffering amortization effect to but low-cost change buffer block after the wearing and tearing, convenient and practical.
