Description
Technical Field
The invention relates to the technical field of battery replacement of new energy vehicles, in particular to a side surface mounting and fixing device for a battery box of a heavy truck.
Background
In recent years, the electric replacement of new energy electric heavy trucks is a trend, and the problem that the economic benefit of heavy trucks is influenced by long battery charging time is well solved. In order to not occupy the limited space of the container, batteries are arranged on two sides of the bottom of the container, so that the trend of replacing the batteries is realized. In addition, the current structure design of the heavy truck is limited, and the space for arranging the battery box on the side surface is limited; therefore, how to fix and lock the battery box on the heavy truck quickly and reliably is a practical problem which needs to be solved urgently at present.
Disclosure of Invention
The battery box is fixedly installed by adopting a simple and reliable structure, so that the volume of the battery box is large enough, the cruising ability of the heavy truck is improved, and the design requirement of automatic replacement of the heavy truck can be met.
The invention achieves the aim through the following technical scheme: a heavy truck battery box side mounting fixture, comprising: the battery box comprises a battery box bracket, a battery box frame, a positioning pin, a limiting block driving cylinder and a limiting block; the battery box frame is connected with the battery box bracket; the locating pin passes through the screw fixation on the battery box support, and the stopper drives actuating cylinder and passes through the screw fixation on the battery box support, and the stopper passes through the spout shape and connects on the battery box support to it links to each other with the extension bar that the stopper drove actuating cylinder.
Preferably, the battery box bracket is provided with a guide port, a support plate and a limit plate; the supporting plate is respectively connected with the guide port and the limiting plate in a welding mode.
Preferably, the battery box frame is provided with a positioning block, and the positioning block is provided with a positioning hole.
Preferably, the battery box support has two, arranges respectively in battery box mounted position's two survey, and battery box support is whole to be welded and is formed, links with the heavy truck girder, forms a stable whole.
Preferably, the battery box support has a simple structure and occupies a small space, and more arrangement space is reserved for the battery box frame under the limit of total space fixation.
The invention has the beneficial effects that: (1) according to the invention, the battery box bracket and the heavy truck chassis girder are fixed, so that the battery box bracket and the heavy truck form a stable whole, and the stability of the battery box is improved; (2) the invention adopts a mode of supporting two sides of the battery box, reduces the space occupation of the battery box bracket and reserves the whole disassembly and assembly space of the battery box.

Detailed Description
The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto:
example (b): as shown in fig. 1, 2, 3 and 4, a heavy truck battery box side mounting and fixing device is composed of a battery box bracket 1 and a battery box frame 2. In the battery box support 1, a guide opening 3, a support plate 4 and a limiting plate 5 are designed, and the guide opening 3, the support plate 4 and the limiting plate 5 are connected in a welding manner. In above-mentioned battery box support 1, be equipped with locating pin 6, stopper and drive actuating cylinder 7, stopper 8, locating pin 6 passes through the screw fixation on battery box support 1, the stopper drives actuating cylinder 7 and passes through the screw fixation on battery box support 1, stopper 8 passes through the spout shape and installs on battery box support 1 to drive the extension bar of actuating cylinder 7 with the stopper and link to each other, drive under actuating cylinder 7's the drive at the stopper, do locking and unblock action in the spout. In the battery box frame 2, a positioning block 9 is designed, and a positioning hole 10 is designed on the positioning block 9.
When the battery box frame 2 is used, the battery bracket 1 is inserted into the battery box frame 2 along the direction of the guide opening 3 by the positioning block 9 in a bottom support or side support mode, after the battery box frame is inserted in place, the positioning block 9 is limited by the limiting plate 5 and cannot be inserted continuously, the battery box frame 2 is moved downwards by an external mechanism, the positioning hole 10 and the positioning pin 6 are mutually guided and matched, the battery box frame 2 is accurately positioned, and the horizontal movement and the rotation freedom degree of the battery box frame 2 are limited. After the positioning block 9 contacts the supporting plate 4, the integral installation action of the battery box frame 2 is completed, the limiting block driving cylinder 7 drives the limiting block 8 to move forwards, the space of the battery box frame 2 moving upwards is locked, the freedom degree of the battery box frame 2 moving vertically downwards is limited, and the locking action of the battery box frame 2 is completed.
According to the invention, the batteries are arranged on the side surface of the heavy truck in a manner of the battery box bracket, so that the space of a container is prevented from being occupied; the left side and the right side are provided with the brackets, so that the battery can be disassembled and replaced, the operation space at the bottom and the side surface is reserved, and the replacement operation of the battery body is convenient; through the mechanisms of the supporting plate, the limiting plate, the positioning pin and the limiting block, the battery box frame is fixed in the battery box support, and the safety and stability of the battery body when the heavy truck runs are guaranteed.
While the invention has been described in connection with specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
