Description

Technical Field

[0001] The utility model relates to a driving chassis structure, in particular to a driving chassis structure suitable for a mobile charging pile. Background Art

[0002] At present, the mobile charging piles on the market adopt the shell envelope design, and the motor is located inside the whole machine. When the mobile charging pile fails on the road and breaks down, the motor is in a locked state. The shell of the whole vehicle wraps the motor. For external users, in order to beautify the appearance of the whole machine and ensure the waterproof level of the internal components of the whole machine, the motor and other components are in a wrapped and hidden design. In addition, the shell of the mobile charging piles on the market is mostly made of pure sheet metal or a combination of composite materials and thin sheet metal, which ensures the waterproofness of the whole machine on the one hand and reduces the weight of the whole machine on the other.

[0003] As the weight of the mobile charging pile increases with the increase of the power of the whole machine, when the mobile charging pile is in a state of collapse, the outer shell of the whole machine has no fulcrum. If force is applied directly to the outer shell, the outer shell will be deformed to varying degrees, affecting the shape of the whole machine. In addition, because the ground clearance of the whole machine chassis is small, the forklift forks cannot enter on some uneven parking lot roads, and the vehicle can only be moved after the relevant personnel have repaired the vehicle. The handling process of this problem seriously reduces the efficiency of the whole machine charging vehicle on the one hand, and may cause congestion in the parking lot on the other hand.

[0004] In view of the design problems of mobile charging pile models on the market before, the utility model proposes a driving chassis structure suitable for the mobile charging pile, so that the mobile charging pile can be both dragged and forked and moved. Utility Model Content

[0031] It should be noted that the above structures are formed by mutual welding, and the welding forms include spot welding, filled spot welding and reinforcement welding of the welds at the cross-contact parts of the corresponding components. On the one hand, the reliability of the mutual connection is guaranteed, and on the other hand, the bearing strength of the driving chassis frame 1 is guaranteed. Technical personnel in this field can determine the welding form according to actual needs, so this application does not limit it.

[0032] Preferably, there are two rear wheel brackets 25, which are respectively mounted on the two corners of the driving chassis frame 1 on the side close to the tail beam 17, and a dragging hole 27 is also provided on the rear wheel bracket 25; there are two auxiliary wheel fixing plates 26, which are respectively mounted on the two corners of the driving chassis frame 1 on the side close to the outer shell fixing plate 19; the motor mounting plate 20 is located between the two auxiliary wheel fixing plates 26, so that the correspondingly installed rear wheel assembly 14, auxiliary wheel 15, and motor wheel 12 can cooperate in movement to enable the driving chassis frame 1 to have a mobile function. In addition, it should be noted that the rear wheel assembly 14 includes a wheel axle, bearings, sleeves, and flanges. The above features are not original technical features of the present application, and therefore are not marked and displayed, and are hereby explained.

[0033] Preferably, the lateral housing fixing plate 18 extends in the same direction as the side beam 16 , and the lateral housing fixing plate 18 is used to support the housing 4 at the edge position of the driving chassis frame 1 .

[0037] A housing electronic lock fixing bracket 24 is also installed on the side of the driving chassis frame 1, and the upper bearing surface of the driving chassis frame 1 has flatness.

[0038] Preferably, the upper part of the driving chassis skeleton 1 carries a battery cluster frame 3, and a plurality of battery packs 13 are placed on the battery cluster frame 3. An upper pile 2 installed on the battery cluster frame 3 is provided directly above the uppermost battery pack 13. The battery cluster frame 3 is connected and installed to the driving chassis skeleton 1 through a bolt assembly. The installation of the battery cluster frame 3, the battery pack 13 and the upper pile 2 is also limited on one side, and fixed on the other side through a bolt assembly and holes.

[0039] The upper part of the driving chassis frame 1 carries a battery cluster frame 3 , on which a plurality of battery packs 13 are placed, and an upper pile 2 mounted on the battery cluster frame 3 is provided just above the uppermost battery pack 13 .
