Detailed Description
The technical solution of the present invention will be further clearly and completely described below with reference to the accompanying drawings and examples.
Examples
Please refer to fig. 3 to fig. 6: the utility model provides a pair of buckle formula fixed establishment that is used for electric motor car to sit bucket interior battery apron, including sitting bucket 1, sit and be equipped with group battery 2 in the bucket 1, the top of group battery 2 has and is used for charging discharging's plug 21, the top of group battery 2 is equipped with battery apron 3, battery apron 3's rear end passes through battery apron swivel pin axle 4 and sits bucket 1 rotatable coupling, the left and right sides of battery apron 3 is equipped with lift-draw formula buckle 5, the one end of lift- draw formula buckle 5 and 3 separable connections of battery apron, the other end of lift-draw formula buckle 5 passes through buckle swivel pin axle 6 and sits bucket 1 lateral wall rotatable coupling, the cover is equipped with buckle swivel spring 7 on the buckle swivel pin axle 6.
Referring to fig. 3 and 5, in the present embodiment, the battery cover plate 3 is provided with a limiting hole 31 adapted to the plug 21 of the battery pack, so that when in use, the plug 21 of the battery pack passes through the limiting hole 31 to limit and fix the battery cover plate 3. In addition, the battery cover plate 3 is provided with engaging portions 32 on both left and right sides thereof, which are adapted to the pull-up type buckle 5, and the battery cover plate 3 and the pull-up type buckle 5 can be detachably connected by the engaging portions 32.
In addition, the cushion of the electric vehicle is clamped with the seat barrel 1 through the battery upper and lower limiting rubbers, and therefore, the front end of the seat barrel 1 is provided with a buckling part used for clamping the battery upper and lower limiting rubbers. The length of the battery cover plate 3 in the embodiment can be equal to that of the sitting barrel 1, and can also be smaller than the inner length of the sitting barrel 1; when the length of the battery cover plate 3 is equal to that of the sitting barrel 1, the front end of the battery cover plate 3 is provided with a through hole for passing through the battery upper and lower limiting rubber like the traditional battery cover plate, so that the cushion is clamped with the sitting barrel 1; when the length of battery apron 3 was less than the internal length of sitting bucket 1, the front end of battery apron 3 can not cover the buckling parts of sitting bucket 1, and at this moment, the front end of battery apron 3 need not to be equipped with the via hole, and spacing rubber about the battery on the cushion can with sit bucket 1 block.
Referring to fig. 6 again, in the present embodiment, the bottom of the pull-up buckle 5 is an inclined surface 51 to have a guiding function, so that when the pull-up buckle 5 is pushed downward, the pull-up buckle 5 is pushed downward.
Referring to fig. 4 and 6, in the present embodiment, one end of the latch rotating spring 7 sleeved on the latch rotating pin 6 extends transversely toward the battery cover plate 3, and the other end of the latch rotating spring 7 extends downwardly.
In this embodiment, the pull-up type buckle 5 and the buckle rotating spring 7 may be commercially available products.
A application method that is used for buckle formula fixed establishment of battery apron in electric motor car seat bucket as follows:
fig. 3 is a state diagram of the battery cover plate 3 when it is clamped and fixed, at this time, the battery cover plate 3 is fixed above the battery pack 2 by the pull-up type buckle 5, one end of the buckle rotary spring 7 is lapped between the battery cover plate 3 and the pull-up type buckle 5, and the other end of the buckle rotary spring 7 hangs down;
when the battery cover plate 3 needs to be opened, the lifting type buckle 5 is lifted upwards in the arrow direction in fig. 4, the lifting type buckle 5 rotates along the buckle rotating shaft pin 6, the buckle rotating spring 7 is compressed under the stress, so that the lifting type buckle 5 is separated from the battery cover plate 3, and the battery cover plate 3 can be controlled by hands to rotate upwards along the battery cover plate rotating shaft pin 4, so that the battery cover plate 3 is opened;
when battery apron 3 is fixed well to needs, bulldoze the lift-draw formula buckle 5 downwards hard, buckle rotating spring 7 atress tightens up, stops the application of force, and buckle rotating spring 7 kick-backs, so, lift-draw formula buckle 5 can block in the both sides of battery apron 3, and battery apron 3 can be by the chucking.
From the above, the battery cover plate 3 is fixed by the lifting type buckle 5 and the buckle rotating spring 7, and the battery cover plate 3 is not fixed by the battery up-and-down limiting rubber 5' on the electric vehicle cushion as shown in fig. 1 and fig. 2, so that the battery cover plate 3 is not limited by the electric vehicle cushion, and can be in a fixed state no matter whether the electric vehicle cushion is opened or not, thereby effectively increasing the safety of battery storage and the reliability of the whole electric vehicle; and, this application only need upwards carry and draw or bulldoze the draw formula buckle 5 downwards and can open or close battery apron 3, has advantages such as easy operation, convenient to use, consequently, the utility model discloses relative prior art has obvious practicality and progressive.
It is finally necessary to point out here: the above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
