DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] Reference Figure 1-Figure 4 A new energy vehicle start-stop battery with a protective device comprises a start-stop battery body 1 and a safety valve 2. The start-stop battery body 1 is detachably connected to the safety valve 2. The safety valve 2 comprises an outer tube 201, a lower assembly 202, and an upper assembly 203. The start-stop battery body 1 refers to a valve-regulated lean glass fiber battery (AGM battery) or an enhanced flooded battery (EFB battery), which mainly meets the needs of the vehicle start-stop system. The start-stop battery body 1 has the characteristics of larger battery capacity, fast charging and discharging, and longer service life. The start-stop battery body 1 of a new energy vehicle is usually incompatible with its own power battery, and the two are independent of each other. New energy vehicles accelerate quickly and move in the city. They often need to stop and wait at traffic lights. Therefore, the start-stop battery body 1 needs to be used multiple times. The number of times it is used is large, and it is also easy for excessive pressure to occur inside.

[0023] It should be noted that the outer tube 201 is divided into an upper tube and a lower tube, the lower tube is fixedly mounted on the outer shell of the start-stop battery body 1, the upper tube is rotatably connected to the lower tube, and a lower assembly 202 is inserted into the outer tube 201. Specifically, a D-shaped frame 2011 is installed in the outer tube 201, and the D-shaped frame 2011 and the inner wall of the outer tube 201 are surrounded to form a plurality of plug-in grooves 2012.

The top of the trapezoidal plate 2021 is provided with an inclined surface, and a lower positioning groove 2013 cooperating with the trapezoidal plate 2021 is provided in the outer tube 201. The lower assembly 202 is provided with a plurality of plug-in parts that match the plug-in groove 2012. A spring 2022 is installed between the trapezoidal plate 2021 and the inner wall of the lower installation groove. The spring 2022 is used to apply a force to move the trapezoidal plate 2021 to the inner side of the lower installation groove (i.e., a force away from the inner wall of the outer tube 201); the D-shaped frame 2011 and the inner wall of the outer tube 201 are surrounded to form four plug-in grooves 2012. Correspondingly, four plug-in parts are provided at the bottom of the lower assembly 202, and a lower installation groove and other components are provided at one of the plug-in parts to fix the relative position between the outer tube 201 and the lower assembly 202;

[0024] In a further embodiment, an insertion rod 2032 is inserted into the upper assembly 203, and a cavity is provided in the upper assembly 203 to allow the insertion rod 2032 to move up and down. The end of the insertion rod 2032 is set to be flush with the inclined surface of the trapezoidal plate 2021, and the insertion rod 2032 is slidably connected to the lower assembly 202. It should be noted that a plurality of auxiliary rods 2031 are installed at the lower end of the upper assembly 203, and the auxiliary rods 2031 are slidably connected to the lower assembly 202;

[0025] In a further embodiment, an upper plug block 2033 is provided in the upper assembly 203, and a vertical groove 2014 and an annular groove 2015 are provided in the outer tube 201 corresponding to the upper plug block 2033. The vertical groove 2014 is connected to the annular groove 2015, and the upper plug block 2033 can slide up and down relative to the vertical groove 2014, and it can rotate relative to the annular groove 2015. An upper positioning block 2034 is installed on the top of the upper assembly 203, and the upper positioning block 2034 can slide up and down along the inner wall of the lifting groove in the upper assembly 203. The outer tube 201 is provided at the position corresponding to the upper positioning block 2034. An upper positioning groove 2016 is provided, two upper positioning blocks 2034 are provided, and the two upper positioning blocks 2034 are evenly spaced and arranged in a circumferential array on the upper assembly 203, the top of the upper positioning block 2034 is fixedly connected to a lifting rod 2035, and the tops of the two lifting rods 2035 are both connected to a pull rod 2036, more specifically, one of the lifting rods 2035 is connected to the upper assembly 203 by a thread, and the other lifting rod 2035 is slidably connected to the upper assembly 203, and the lifting rod 2035 connected to the upper assembly 203 by a thread is rotatably connected to the pull rod 2036;

[0026] The upper assembly 203 is provided with a valve assembly 2037, which includes a valve plate 20371. The valve plate 20371 is rotatably connected to the upper assembly 203. A lower crescent plate 20372 is provided on the lower side of the valve plate 20371, and an upper crescent plate 20373 is provided on the upper side. An elastic component is provided between the upper crescent plate 20373 and the valve plate 20371, and the elastic component can give the valve plate 20371 a force to rotate downward. The upper crescent plate 20373 and the lower crescent plate 20373 are connected to each other. 20372 are aligned up and down; the valve plate 20371 can rotate around the middle valve core, and its lower side is blocked by the lower crescent plate 20372 and cannot rotate, and can only rotate upward. The upper crescent plate 20373 on the upper side applies pressure to it through the elastic component. When the internal pressure of the start-stop battery body 1 is too high, the valve plate 20371 is squeezed to rotate upward, and the gas inside is discharged, which can prevent the battery from expanding due to excessive pressure. Conversely, the valve plate 20371 will close the outlet.

[0027] When installing the safety valve 2, first, insert the lower assembly 202 from top to bottom into the bottom of the outer tube 201, and move it down to the position of the D-shaped frame 2011. Then, insert the upper plug block 2033 in the upper assembly 203 into the upper tube in the outer tube 201 along the vertical groove 2014. After inserting it to the height of the annular groove 2015, rotate the upper tube to allow the upper plug block 2033 to be inserted into the annular groove 2015. Then, insert the upper positioning block 2034 into the upper positioning groove 2016 to complete the installation of the entire safety valve 2. The three connected components are multi-locked at the connection points and will not fall off.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
