Specifically, the battery assembly comprises a battery box arranged on the frame and a battery arranged in the battery box. The electric carrier vehicle is reasonable in design, reliable in structure and mainstream in the market.

However, as the user's demand for battery life increases, the drawbacks of this structure begin to manifest themselves. Specifically, the volume of the battery is larger and larger to meet the requirement of battery endurance time. When the battery needs to be maintained, replaced and the like, the battery needs to be taken out, however, in the conventional structure, the mode of taking out the battery box from the bottom to the top is increasingly difficult due to the increase of the volume and the weight of the battery. In addition, the design of the entire vehicle is often more compact due to the design concept of reducing the weight and size of the vehicle body. For better space utilization, components originally placed on the outside, such as a hydraulic assembly and a charger assembly, are often placed above the battery box. This makes removal of the battery box more difficult.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment 1, a lightweight transportation vehicle, as shown in fig. 1, includes a main frame 1, and the main frame 1 is driven by a lift-up unit such as a hydraulic system (not shown) to be lifted up and down in a vertical direction. The main frame 1 is connected at its front end, i.e. in a direction away from the forks 2, to drive wheels, handles or the like. The driving wheel, the handle and the jacking assembly can be the same as those in the prior art, and the invention is not modified and is not described again.

The rear side of the main frame 1 is connected with two forks 2, and the two forks 2 are used for loading cargoes. The main frame 1 has the shape of a rectangular box body including a partition plate 11, as shown in fig. 1 and 2, dividing the rectangular box body into upper and lower two accommodation areas, i.e., a lower main accommodation chamber 13 and an auxiliary accommodation chamber 14. The main container 13 is provided with a vertically extending connecting plate 16 which connects the bottom surface of the main container 13 and the partition 11. This is because the main frame 1 needs to have a certain structural strength as a stressed member, and the connecting plate 16 plays a role in strengthening the stress in the jacking process. The main accommodating chamber 13 is used for accommodating the batteries 4, and due to the influence of the connecting plate 16, in the present case, two batteries 4 are provided and are respectively arranged in the spaces at two sides of the connecting plate 16.

In the sub-accommodation chamber 14, components such as a hydraulic pump station, a charger, a fuse, and an electric wire harness can be placed.

As shown in fig. 2, the rear side of the main frame 1, i.e., the side close to the forks 2, is provided with an opening 15. When the battery needs maintenance or repair, the user puts or takes out the battery 4 through the opening 15. Under this kind of design, battery 4 no longer goes up and down through vertical direction and gets into body frame 1, and this has avoided the inconvenience that heavy weight bulky battery goes up and down to bring promptly, can not bring the interference to the article of putting on baffle 11 and baffle 11 either. Even if the battery 4 is taken out in the horizontal direction, it is taken out from the rear side of the main frame 1, not from the side. This is because the light weight, miniaturized vehicle design, it is required that the vehicle possess less automobile body length to its turning radius is littleer, in order to adapt to the requirement of narrow tunnel. When the main frame 1 is taken out from the side, the main frame must be enlarged in the longitudinal direction of the vehicle body to facilitate the operation, and the turning radius must be increased.

In the present embodiment, since the battery 4 is taken out from the rear side of the main frame 1, the user can obtain a good operation space without affecting the length of the vehicle body because the width of the vehicle is large, that is, the width of the main housing compartment 13 is large.

As shown in fig. 2 and 3, the cover plate 3 is used to cover the opening 15 in a normal state. The cover plate 3 is hinged with the main frame 1 and overturns in the vertical direction. When the cover plate 3 is turned down, the cover plate directly rests on the upper surfaces of the two forks 2, and one surface of the cover plate 3 close to the main frame 1 is designed into a flat resting plane 31. When the battery 4 needs to be taken out for maintenance, the battery 4 only needs to be taken out and placed on the laying plane 31, the battery 4 does not need to be completely detached and kept away from the vehicle, and therefore the working efficiency is greatly improved.

The left and right sides position of apron 3 is equipped with the upset strip 33 of vertical direction extension. As shown in fig. 3, the main frame 1 is provided with a pin 6 extending in the horizontal direction. The turning strip 33 is provided with a matching hole 34 for being sleeved in the pin shaft 6. The whole turning plate 3 is turned over in the vertical direction by taking the pin shaft 6 as an axis. A gap 341 is formed in the fitting hole 34, which makes it easier to mount or dismount the cover plate 3. For example, during the installation process, the user only needs to forcibly buckle the cover plate 3 down so that the pin 6 enters the fitting hole 34 from the notch 341. The installation of the components is avoided by performing actions such as rotary plugging and unplugging on the pin shaft 6 in a narrow space.

As shown in fig. 4 and 5, a buffer block 32 made of an elastic material is included on a surface of the cover plate 3 adjacent to the main frame 1, and when the cover plate 3 is closed by a user, the front side surface of the battery 4 abuts against the main frame 1 and the rear side surface abuts against the buffer block 32, so that the battery 4 has a good flexible abutting retention effect.

A connecting plate 16 is connected to the partition 11, and extends in a vertical direction, so that a user can connect the cover plate 3 to the connecting plate 16 using an upper fixing member 5, and the upper fixing member 5 may be a common fixing member such as a bolt.
