An oil chamber for accommodating hydraulic oil is formed between the first piston plate 17 and the bottom plate of the oil reservoir 3. The first piston plate 17 can be driven to move up and down in the oil reservoir 3 when the telescopic part is telescopic, so that hydraulic oil is pressed out of the oil reservoir 3 or hydraulic oil is sucked into the oil reservoir 3.
The oil path pipe 2 is arranged on the base 1, and the oil path pipe 2 specifically comprises a vertical pipe and a horizontal pipe. The vertical pipe and the horizontal pipe are mutually communicated to form an L shape. The mouth of the horizontal pipe is communicated with the oil storage tank 3, a second piston plate 18 is arranged in the vertical pipe, the second piston plate 18 is in sealing fit with the vertical pipe, the second piston plate 18 has a blocking effect on hydraulic oil, and the hydraulic oil is prevented from leaking out through the mouth of the vertical pipe. The second piston plate 18 is connected to the movable rod 7. One end of the movable rod 7 extends out of the vertical pipe and is connected with the top plate 8. A battery rack 15 is provided on the top plate 8.

In this way, the connecting beam 14, the middle plate 5 and the side wing plate 6 are connected as a whole, thereby improving the stability of supporting the telescopic device and the stability of limiting the oil pipe 2.
The middle plate 5 is far away from one end of the base 1, or the top end of the middle plate 5 is provided with a guide hole part, a first guide hole is arranged in the guide hole part, a first guide rod 13 is arranged on the surface of the top plate 8 facing the base 1, and the first guide rod 13 is matched in the first guide hole.

The provision of the diagonal portion allows the connecting beam 14 to be connected at any height on the diagonal portion. The provision of the bevel portion thus increases the application range of the middle plate 5. The length of the connecting beam 14 also needs to be changed when adjusting the height of the connecting beam 14 according to the telescopic means to ensure that both ends of the connecting beam 14 can be connected to the bevelled portions of the two middle plates 5.
The oil storage tank 3, the oil pipe 2, the first piston plate 17, the second piston plate 18, the connecting beam 14, the middle plate 5, the side wing plates 6 and the movable rod 7 form a height rough adjusting mechanism. The height of the top plate 8 and the battery rack 15 thereon are adjusted by the height adjusting mechanism. Next, fine adjustment of the height of the battery holder 15 will be described.
The fine adjustment mechanism comprises a bracket 9, a motor 10, a screw rod 11 and an internal threaded square tube 16. Specifically, the bracket 9 is provided on the side of the top plate 8 facing the base 1, or the bracket 9 is provided on the bottom surface of the top plate 8. The bracket 9 is provided with a motor 10. The top plate 8 forms a suspension for the bracket 9 and the bracket 9 forms a support for the motor 10. The motor 10 is vertically arranged, the motor 10 shaft of the motor 10 is connected with a screw rod 11, and an internal thread square tube 16 is in threaded fit with the screw rod 11. The top plate 8 is provided with square through holes which are matched with the internal thread square pipes 16. The internally threaded square tube 16 is arranged vertically. The top end of the internally threaded square tube 16 is connected to the battery holder 15. The bracket 9 is generally of an upwardly open C-shaped configuration. Two flanging plates of the bracket 9 are welded on the bottom surface of the top plate 8, and an internally threaded square pipe extends out of the opening of the bracket 9.
The motor 10 shaft can drive the lead screw 11 to rotate, and the internal thread square tube 16 in threaded fit with the lead screw 11 cannot rotate along with the lead screw 11 due to square fit relation with the through hole, so that the internal thread square tube 16 can move up and down, thereby driving the battery frame 15 to move up and down, and realizing fine adjustment of the height of the battery frame 15.
In the embodiment of the utility model, the outer wall of the internal thread square tube 16 is provided with a strip-shaped convex rib 161, and correspondingly, the inner wall of the through hole of the top plate 8 is provided with a through groove, and the convex rib 161 is in sliding fit in the through groove. When the internally threaded square pipe 16 moves up and down, the bead 161 moves up and down in the through groove. The cooperation of the ribs 161 and the through grooves ensures the stability of the upward and downward movement of the internally threaded square tube 16, and thus the stability of the upward and downward movement of the battery frame 15.
Further, in the embodiment of the present utility model, a bead 161 is respectively disposed on four outer walls of the internally threaded square tube 16, and a through groove is respectively disposed on four inner walls of the via hole of the top plate 8.

The second guide bar 12 is fitted into the second guide hole. During the up-and-down movement of the battery frame 15, the second guide bar 12 moves up and down along the second guide hole, and the battery frame 15 moves up and down stably due to the cooperation of the second guide bar 12 and the second guide hole.
Specifically, the second guide bars 12 may be provided in four, two second guide bars 12 of the four second guide bars 12 are provided at one side of the battery frame 15, and the other two second guide bars 12 are provided at the other side of the battery frame 15.
The principle of the height adjusting device of the battery rack 15 in the utility model is as follows: first, rough adjustment of the height of the battery rack 15 is performed: the hydraulic cylinder 4 is started, the hydraulic cylinder 4 pushes the first piston plate 17 to move downwards, hydraulic oil in the oil storage tank 3 is pressed into the oil path pipe 2, the hydraulic oil entering the oil path pipe 2 pushes the movable rod 7 and the top plate 8 to move upwards through the second piston plate 18, and the battery rack 15 arranged on the top plate 8 moves upwards along with the movable rod. Thus, coarse adjustment of the height of the battery rack 15 is achieved.
The battery rack 15 is then fine-tuned in height: the motor 10 is started, so that the motor 10 drives the screw rod 11 to rotate, the screw rod 11 drives the internal threaded square pipe 16 to move up and down, and the internal threaded square pipe 16 drives the battery rack 15 to move up and down. Fine adjustment of the height of the battery frame 15 can be achieved by controlling the angle of rotation of the motor 10.
