Description
Technical Field
The utility model belongs to the technical field of vehicle-mounted battery replacement equipment, and particularly relates to an automatic gap compensation device for a heavy truck top replacement battery box.
Background
With the development of new energy electric vehicles, according to the actual needs of large electric vehicles and other trucks, the country proposes to gradually adopt a power conversion mode to meet the actual needs of the electric vehicles for quickly supplementing energy; in the current market, most of battery packs are placed on top of battery packs, and when the vehicle runs, the battery packs can be in front-back, left-right swing and jolt up and down states along with the starting, braking, turning, uneven road and other working conditions of the vehicle. Especially front-back, side-to-side, is the most dangerous for the vehicle. Because the battery box is replaced, the battery box can be installed and fixed on the vehicle by the locks at the four corners on the base and fixedly connected with the base, and the base is fixed on the vehicle girder by bolts. However, due to machining deviation, gaps exist between the battery box and the base, and thus the battery box for battery replacement tends to swing forwards and backwards and leftwards and rightwards in vehicle-mounted running.
Disclosure of Invention
The technical scheme is as follows: in order to solve the technical problems, the utility model provides the automatic gap compensation device which can reduce the shaking of the automatic gap compensation device and ensure the running safety of a battery-changing vehicle, and particularly provides the automatic gap compensation device for the heavy-duty top-replacement battery box, comprising the heavy-duty top-replacement battery box, a base, a steel ball, a rollaway nest and a pit track; the bottom of the heavy truck top replacement electric battery box is of an inverted trapezoid structure; the base is of an opening structure matched with the inverted trapezoid structure, and the bottom of the base is fixed on a girder of the vehicle through bolts; the roller path is arranged at the bottom of the heavy truck top replacement electric battery box; the pit track is in a plurality of arc pit structures and is distributed on a base stress surface where the base is contacted with the heavy truck top replacement electric battery box at intervals; the steel ball is placed in a gap between the heavy truck top replacement electric battery box and the base after the heavy truck top replacement electric battery box is contacted with the base.
As an improvement, when the heavy truck top replacement electric battery box is contacted with the base, the steel balls can roll down from the gap into the pit track or/and the rollaway nest.
The roller path is arranged at the bottom of the heavy truck top replacement electric battery box in a welding mode.
As an improvement, the cross section of the pit track is an arc pit, and the diameter of the pit track is slightly larger than that of the steel ball.
The beneficial effects are that: according to the gap automatic compensation device for the heavy truck top replacement electric battery box, provided by the utility model, the gap between the battery box and the support is automatically supplemented by utilizing the dead weight through the balls below the battery box, when the battery box is laterally rocked, the rocking force of the battery box is transferred to the balls, the force of the steel balls is supported by the pits of the base, the rocking force of the battery box is transferred to the base, the battery box is prevented from rocking, the rocking is reduced, and the stability of the battery box is ensured.

FIG. 3 is a schematic view of the force applied to a steel ball according to the present utility model.
In the figure: the heavy truck top replacement electric battery box 1, the base 2, the steel ball 3 and the pit track 4.
Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.
The automatic gap compensation device of the heavy truck top replacement electric battery box comprises a heavy truck top replacement electric battery box 1, a base 2, a steel ball 3, a roller path and a pit track 4; the bottom of the heavy truck top replacement electric battery box is of an inverted trapezoid structure; the base is of an opening structure matched with the inverted trapezoid structure, and the bottom of the base is fixed on a girder of the vehicle through bolts; the roller path is arranged at the bottom of the heavy truck top replacement electric battery box; the pit track is in a plurality of arc pit structures and is distributed on a base stress surface where the base is contacted with the heavy truck top replacement electric battery box at intervals; the steel ball is placed in a gap between the heavy truck top replacement electric battery box and the base after the heavy truck top replacement electric battery box is contacted with the base.
As shown in fig. 1, the steel balls are placed in the gap between the heavy truck top replacement electric battery box 1 and the base 2. As shown in fig. 2, the battery box shakes during the running process of the vehicle, and the steel ball 3 rolls down along the inclined surface of the base due to gravity and falls into the pit track 4 or continues to roll down until in the raceway.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
