Description

Technical Field

[0001] This utility model relates to the field of cargo handling vehicle technology, and more specifically, to a battery cover opening and closing structure for a cargo handling vehicle. Background Technology

[0002] A cargo handling vehicle is a transport device used to move goods. Currently, the battery cover installed on the frame of a cargo handling vehicle is fastened to the frame with bolts. When it is necessary to inspect the battery located on the frame, the maintenance personnel need to remove the bolts used to fix the battery cover and remove the battery cover from the frame, which is inconvenient for battery maintenance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a battery cover opening and closing structure for a transport vehicle, wherein the battery cover inside can be rotated and opened relative to the vehicle frame without removing the battery cover from the vehicle frame, thereby facilitating the maintenance process of the battery.

[0004] This utility model provides a battery cover opening and closing structure for a transport vehicle, including a frame and a battery cover; the frame is provided with a battery compartment with an opening at the top, the front side of the battery cover is rotatably connected to the frame, and the rear side of the battery cover forms a free end; when the free end of the battery cover abuts against the frame, the battery cover is used to cover the opening at the top of the battery compartment; two symmetrical iron blocks are fixed on the inner side of the free end of the battery cover, and magnets corresponding to the two iron blocks are fixed on the frame, each magnet magnetically attracting the corresponding iron block to lock the battery cover onto the frame.

[0005] By adopting the above-described structure, the front of the battery cover is rotatably connected to the frame, and the rear of the battery cover is locked to the frame by the magnetic attraction of an iron block and a magnet. Therefore, when it is necessary to inspect the battery located in the battery compartment, the battery cover can be rotated open relative to the frame without removing the battery cover from the frame, which facilitates the battery inspection process. In addition, since the rear of the battery cover is locked to the frame by the magnetic attraction of an iron block and a magnet, it has the advantage of easy locking of the battery cover to the frame.

[0006] In one possible implementation, the battery cover opening and closing structure of the transport vehicle further includes two mounting seats; each magnet is embedded in the upper end of one of the mounting seats, and a screw is coaxially provided at the lower end of each mounting seat. The screw is threaded onto the frame, and a locking nut threaded onto the screw is fitted onto the screw, with the locking nut tightly abutting against the frame. With this structure, the magnet can be reliably fixed to the frame by the mounting seats, and the locking nut, due to its tight abutment against the frame, prevents the screw from rotating freely relative to the frame, thus reliably fixing the mounting seats and magnets to the frame.

[0007] In one possible implementation, the battery cover opening and closing structure of the transport vehicle further includes a rotating arm; one end of the rotating arm is fixed to the middle of the front side of the battery cover, and the other end of the rotating arm is rotatably connected to the vehicle frame; by adopting this structure, the front side of the battery cover can be reliably rotatably connected to the vehicle frame under the action of the rotating arm.

[0008] In one possible implementation, one end of the rotating arm extends into the interior of the front side of the battery cover, and a connecting plate is welded and fixed to one end of the rotating arm. The connecting plate is fixed to the inner wall of the front side of the battery cover. With this structure, one end of the rotating arm can be reliably fixed to the inner wall of the front side of the battery cover by the connecting plate. In addition, the connecting plate is fixed to the inner wall of the front side of the battery cover by several screws.

[0009] In one possible implementation, a rotating sleeve is welded and fixed to the other end of the rotating arm. The two ends of the rotating sleeve abut against the frame. Two bolts that are symmetrically arranged on the left and right are threaded onto the frame. The threaded parts of the two bolts are axially inserted into one end of the rotating sleeve. The inner walls of the two ends of the rotating sleeve are respectively attached to and rotatably engaged with the outer wall of the threaded part of one of the bolts. With this structure, under the action of the two bolts, the rotating sleeve can be reliably rotatably connected to the frame, that is, the other end of the rotating arm can be reliably rotatably connected to the frame.

[0010] In one possible implementation, a handle is provided at the center of the outer top of the battery cover; by providing a handle at the center of the outer top of the battery cover, when the battery cover needs to be rotated open relative to the vehicle frame, the battery cover can be pulled by the handle, thereby facilitating the rotation of the battery cover relative to the vehicle frame.
