As shown in fig. 1-5, the utility model provides a technical solution: the automatic ejecting centrally-mounted battery box comprises a centrally-mounted battery box body 1, a driving motor shaft 2, a centrally-mounted battery 3 and a battery lock 4 are fixedly mounted inside the centrally-mounted battery box body 1 respectively, the battery lock 4 can lock the centrally-mounted battery 3, the centrally-mounted battery 3 is electrically connected with the driving motor shaft 2, a battery cavity 101 is formed inside the centrally-mounted battery box body 1, the battery cavity 101 is matched with the centrally-mounted battery 3, an ejection mechanism 5 is fixedly mounted at the bottom of the battery cavity 101, the ejection mechanism 5 is abutted to the bottom of the centrally-mounted battery 3, the centrally-mounted battery 3 comprises a battery bottom shell 302, a battery block 303 is mounted inside the battery bottom shell 302, a battery top cover 301 capable of sealing the battery block 303 is further fixedly mounted at the top of the battery bottom shell 302, a sealable charging port 304 and a USB port 305 are fixedly mounted at the top of the battery top cover 301 respectively, the charging port 304 and the USB port are electrically connected with the battery block 303 respectively, the battery lock 4 comprises a telescopic lock tongue 401, the lock tongue 401 can extend into the battery cavity 101, a lock groove 306 matched with the lock tongue 401 is formed in one side of the battery top cover 302, and an ejection groove 307 is arranged at the bottom of the battery shell 302.

As shown in fig. 6 and 7, in the present embodiment, the ejection mechanism 5 includes a fixed tube 501, a sliding tube 502 is slidably connected inside the fixed tube 501, one end of the sliding tube 502 penetrates through a top wall of the fixed tube 501 and extends to the outside of the fixed tube 501, a telescopic spring 503 is further placed inside the fixed tube 501, two ends of the telescopic spring 503 respectively abut against a bottom wall of the fixed tube 501 and a bottom of the sliding tube 502, a weight reduction cavity 504 is opened inside the sliding tube 502, the weight of the sliding tube 502 is light due to the weight reduction cavity 504, so that a large ejection force can be provided when the telescopic spring 503 is ejected, the fixed tube 501 and the sliding tube 502 are both made of hard alloy tubes, and the fixed tube 501 and the sliding tube 502 are both made of hard alloy tubes, so that the fixed tube 501 and the sliding tube 502 have good wear resistance and good strength, the fixed tube 501 and the sliding tube 502 are not easily deformed and damaged during long-term use, and the service life of the ejection mechanism 5 is further prolonged.

Meanwhile, it should be noted that although only one ejection mechanism 5 and one ejection slot 307 are provided in the present embodiment, in order to better eject the centrally-mounted battery 3 in centrally-mounted battery cases 1 of different sizes and models, a plurality of ejection mechanisms 5 may be reasonably provided at the bottom of the battery cavity 101 in the centrally-mounted battery case 1, and a plurality of ejection slots 307 adapted to the ejection mechanisms 5 are provided at the bottom of the battery bottom case 302, thereby facilitating the top of the centrally-mounted battery 3.

Meanwhile, it should be noted that, as shown in fig. 4, in the actual production process, the battery bottom case 302 and the battery top cover 301 of the center-set battery 3 are fixedly connected through fastening screws, and when the ejecting slot 307 is arranged at the bottom of the battery bottom case 302, the ejecting slot may be preferably arranged at the bottom of the threaded hole on the battery bottom case 302, because the threaded hole has a relatively thick thickness and has a fastening screw reinforcing reason, the strength of the position of the battery bottom case 302 at the bottom of the threaded hole is relatively good, so that when the ejecting mechanism 5 ejects the center-set battery 3, the center-set battery 3 hardly deforms, and therefore, the center-set battery 3 can be protected, and the service life of the center-set battery 3 is prolonged.

The battery lock 4 adopted in the embodiment is the most common spring lock on the market, the bolt 401 can retract when a key is used for screwing, when the key is not used for screwing, the bolt 401 can automatically eject, therefore, when the middle battery 3 needs to be taken out from the middle battery box body 1, only the key needs to be inserted into the battery lock 4, when screwing is carried out, the bolt 401 retracts into the battery lock 4 from the locking groove 306, further, due to the lack of the limiting function of the bolt 401, the sliding pipe 502 applies thrust to the threaded hole at the bottom of the middle battery 3 under the elastic force of the telescopic spring 503, then the middle battery 3 ejects out of the battery box body 1 under the action of the middle thrust, when the middle battery 3 needs to be installed into the middle battery box body 1, only the middle battery 3 needs to be pressed down along the track coinciding with the battery cavity 101, when the middle battery 3 applies pressure to the sliding pipe 502 under the pressing, the telescopic spring 503 is compressed, when the middle battery 3 is pressed to the bottom, the bolt 401 ejects into the locking groove 306, then the bolt can limit the middle battery 3 can limit the middle battery cavity 101, and the middle battery 3 can not shake when the middle battery box body is pressed, and the middle battery 3 can not generate larger tolerance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
