Description

[Technical field]

[0001] The present application relates to the technical field of battery swapping, and in particular to a lifting battery swapping transport vehicle. [Background technology]

[0002] Energy conservation, environmental protection, and safety are the main themes in the development of automobiles, and electrification, smartification, internet connectivity, and sharing are the means to achieve them. However, the current driving range of electric vehicles is short, and the number of charging stations is small, which has some impact on the popularization and application of electric vehicles.

[0003] In the prior art, some solutions meet the charging needs by increasing the number of charging stations, while others adopt removable and replaceable driving batteries. The former is a good technical solution for passenger cars with a relatively short daily driving distance because the charging time is too long, but is not suitable for commercial vehicles such as heavy vehicles that require a large driving battery capacity. The latter is suitable for both passenger cars and commercial vehicles, but the center of gravity of the driving battery is too high, the installation reliability is low, and it is difficult to replace it quickly. For example, in the Chinese patent "Truck with Battery Exchange and Charging Function and Its Power Supply Method" of Shanghai Jiuhang Energy Technology Co., Ltd. of the People's Republic of China, a rectangular battery box is fixed to the vehicle, but the battery box has a problem that the center of gravity is too high and unstable. The Chinese patent "Hoisting Battery Exchange Type Container AGV Transport Vehicle" discloses that a battery box frame is installed above two battery division boxes, and the battery frame is further installed on a side member by a positioning mechanism, but both the battery box structure and the positioning structure are too complicated, costly, and the installation stability is insufficient. Summary of the Invention [Problem to be solved by the invention]

[0014] Furthermore, the first locking portion includes a plurality of first locking members, and the plurality of first locking members are disposed surrounding an outer surface of the middle portion.

[0015] The second locking portion includes a plurality of second locking members, and the plurality of second locking members are provided in one-to-one correspondence with the plurality of first locking members.

[0016] Furthermore, the locking device further includes a fastening member.

[0017] The first locking member includes a lock through-hole, and the second locking member includes a lock pillar that fits into the lock through-hole, and the lock pillar can pass through the lock through-hole and fit into the fastening member to connect.

[0021] The first lock body has a lock cavity that fits with the lock assembly, and the protruding steel pillar and the two lock steel pillars are both installed in the lock cavity. The lock cavity has a first opening and a second opening opposite the first opening.

[0022] The first lock body can extend into the second lock body, and the drive rod can extend into a lock cavity to control the position of the protruding steel post.

[0023] The position of the protruding steel pillar is controlled by the driving rod, so that the protruding steel pillar protrudes from the first opening and the second opening, respectively, and engages with the inner wall of the second lock body to realize locking; or the position of the protruding steel pillar is controlled by the driving unit to keep the two locking steel pillars within the second lock body to realize unlocking.

[0031] The embodiment of the present application discloses a hoisting battery exchange type transport vehicle equipped with a battery box 1. With reference to Figs. 1 to 3, Fig. 1 is a structural schematic diagram of the battery box 1, and Fig. 2 is a plan view of the battery box. Fig. 3 is a perspective schematic diagram of the battery box. As shown in Figs. 1 to 3, the battery box 1 has an inverted concave-shaped cross section, and is attached in a saddle-like manner to a side member 2 of the transport vehicle via a locking device. The battery box 1 includes a battery and a battery frame. Among them, the saddle-like shape means that the concave-shaped battery box is turned upside down and placed on the side member, and the concave portion of the battery box is supported by the side member. As shown in Fig. 4, Fig. 4 is a schematic diagram of the engagement between the battery box and the side member according to the embodiment of the present application. The battery box 1 has an inverted concave-shaped structure, and is configured so that the middle part of the inverted concave-shaped structure is connected to the top of the side member 2, and both sides of the middle part are connected to the side parts of the side member 2. Compared to the prior art (shown in FIG. 5) in which the battery box has a rectangular parallelepiped structure and is entirely attached to the body, this configuration effectively lowers the center of gravity of the battery box 1, thereby increasing the stability of the battery box 1.
