Furthermore, the handle structure 340 may include a handle bar connected between the first links 332 of the two push rod link structures 330 at both sides, and the handle bar may facilitate simultaneous push-pull rotation of the first links 332 of the two push rod link structures 330. Further, the handle bar may be connected between the top ends of the two first links 332 (referring to the end of the first link 332 away from the guide rail 310). In addition, the handle structure 340 may further include a first rotating shaft connected between the first connecting rods 332 at two sides, and the second connecting rods 334 of the push rod connecting rod structures 330 at two sides are respectively rotatably connected to two ends of the first rotating shaft, so that the first connecting rods 332 and the second connecting rods 334 of the push rod connecting rod structures 330 at two sides are hinged through the first rotating shaft, and the connection is more stable. Moreover, the second connecting rods 334 of the push rod connecting rod structures 330 on both sides are also hinged through the second rotating shaft, i.e. the two second connecting rods 334 are respectively rotatably disposed at both ends of the second rotating shaft. And the first rotating shaft and the second rotating shaft are fixedly connected through an intermediate connecting rod. Therefore, the stress on the second connecting rod 334 and the pin 332 on the two sides is more balanced, and the pin 332 on the two sides can be pushed and pulled more stably and reliably by the handle.
In addition, the invention further provides a new energy automobile which comprises the new energy automobile battery fixing structure. The new energy automobile with this battery fixed knot constructs can realize power battery's quick replacement, accords with future new energy automobile development direction.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
