Description
Technical Field
The invention relates to an unlocking mechanism, in particular to a battery pack horizontal button unlocking mechanism, and also relates to a battery pack adopting the mechanism, belonging to the technical field of battery power supply devices.
Background
Battery powered power devices such as power tools are commonly provided with a battery pack that is inserted through a kinematic pair and then positively locked by means of a latching mechanism. In the prior art, the latch mechanism is mainly of two types, and a typical structure of the first type is disclosed in Chinese patent No. ZL200910207248.4, wherein the latch which tends to lift and lock is controlled by a vertically operated button to lower and unlock; a second type of typical construction is disclosed in U.S. patent No. US6168881, which discloses a latch that tends to lock in a cantilever fashion by a horizontally operated button to control the release of the cantilever. The former has simple structure and reliable control; the unlocking of the latter is coordinated with the action of pinching the battery pack for drawing and disassembling, and the operation is convenient.
In addition, there is a latch mechanism having a different direction of application of force from the direction of unlocking, and the structure is disclosed in chinese patent No. 200510093985.8: one end of the lock latch is horizontally hinged, the other end of the lock latch tends to be lifted and locked, two sides of the lock latch are respectively combined with two lever type buttons hinged vertically at the middle part through inclined planes, and when the two lever type buttons swing around the hinged supporting points respectively in the horizontal direction, the lock latch is pressed down through the inclined plane pair to unlock, so that the lifting action of the lock latch can be controlled by horizontal force application. However, the lever type button structure is mainly designed for realizing that the lever swings to automatically push out the battery pack, so that the inclined plane pair cannot keep stable surface contact in the unlocking process, and the swing displacement of the button and the lifting displacement of the lock bar have nonlinear relation, so that the control hand feeling is poor.
In addition, the battery pack is generally "one pack with multiple machines" -that is, the same vertical unlocking structure is adopted for all the hosts of various electric tools, once the unlocking structure needs to be changed into a horizontal driving, the structure disclosed by 200510093985.8 needs to be changed into the corresponding adapting structure of the host at the same time, which cannot be realized for the host which has been put into the market in a large number.

The inclined plane pair formed by the latch and the unlocking button in the latter two forms is a high pair, and the method is also feasible.
When unlocking, the left unlocking button and the right unlocking button are oppositely kneaded, and the lifting trend of the lock latch can be overcome through the inclined plane pair which is always attached, so that the lock latch is lowered and unlocked. In the process, the inclined plane pair always keeps the linear relation between the horizontal displacement of the unlocking button and the lifting displacement of the lock latch, so that the operation is stable and flexible. In particular, the structure of the invention can keep the adaptation with various original hosts, thereby solving the adaptation problem of the battery pack after modification and the products in the market.
The invention is further perfected as follows:
The lock latch consists of a pair of left lock button and right lock button, and the lower parts of the left lock button and the right lock button are respectively provided with a boss which forms a vertical moving pair with the left guide post and the right guide post through a center hole.
The boss is internally provided with a vertical ring groove for accommodating the lock button spring, the bottom of the guide post is fixed on the base plate in the shell, and the lower end of the lock button spring is propped against the base plate of the shell.
The left and right lock buttons respectively form lower inclined planes extending from the corresponding bosses.
The outer end of the lower inclined surface is provided with a groove hook head which is upwarp to form a limit groove, the unlocking inclined surface is attached to the opposite lower inclined surface, and the lower end of the unlocking inclined surface is restrained in the limit groove.
The upper parts of the inner sides of the left unlocking button and the right unlocking button respectively extend inwards to form a left unlocking convex and a right unlocking convex which are provided with horizontal holes and are provided with unlocking inclined planes at the inner ends.
Guide pins are inserted into opposite horizontal holes of the left unlocking button and the right unlocking button, and the inner sides of the left guide bulge and the right guide bulge respectively lean against a reset spring sleeved on the guide pins.
