DETAILED DESCRIPTION

[0017] A new energy vehicle battery box installation and positioning structure, see Figure 1-Figure 3 :It includes a battery box 1, and two rows of parallel rollers 2 are arranged at the bottom of the battery box 1. The arrangement direction of each row of rollers 2 is arranged along the front and rear direction of the battery box 1. It also includes a slide rail seat 3, which is fixed to the installation bottom plate of the corresponding electric box space of the new energy vehicle. The slide rail seat 3 is arranged below the bottom position of the corresponding battery box 1. The slide rail seat 3 includes a front end stop rod 31 and guide rods 32 on both sides. At least one guide block 4 is fixed at the corresponding position of the facing end faces of the guide rods 32 on both sides. The guide blocks 4 at the corresponding positions of different guide rods 32 are arranged in pairs. The guide blocks 4 are symmetrically arranged about the length mid-vertical plane of the front end stop rod 31, and the inner end surface of each guide block 4 includes a front guide bevel 41, a middle guide plane 42, and a rear guide bevel 43. The spacing between the middle guide planes 42 of the paired guide blocks 4 is the width occupied by the two rows of rollers 2. At least one column hole 5 is provided in the height direction of the front end stop rod 31, and a protruding column 6 is provided at the corresponding position of the column hole 5 at the bottom front end of the battery box 1. After the battery box 1 is installed in place, the column 6 is clamped in the column hole 5, and the column 6 is tightly matched with the corresponding column hole 5.

[0018] Each row of rollers 2 is installed at intervals on a roller frame 7, and the roller frame 7 is fixed to the corresponding position of the bottom plate of the battery box 1. The lower end surface of the roller frame 7 is open, and the rollers 7 in the working state are supported on the installation bottom plate corresponding to the battery box space. The length of the middle guide plane 42 of each guide block 4 at least covers the distance between two rollers 7, ensuring the guiding effect of the guide block 4;

[0019] The corresponding guide blocks 4 are fixedly mounted at the middle positions of the length direction of the facing end faces of the guide rods 32 on both sides. The arrangement of a pair of guide blocks 4 makes the cost of the whole structure low and ensures the effect of being in place.

[0020] Two clamping column holes 5 are arranged in the height direction of the front end stop rod 31, and the position of each clamping column hole 5 corresponds to the corresponding position of the roller frame 7. The front end of each roller frame 7 is respectively provided with a forward protruding clamping column 6, which ensures that the entire structure can be installed quickly and conveniently;

[0021] A vertical locking threaded hole 8 is provided at the rear end of the guide rod 32, a locking connecting plate 9 is fixedly connected to the bottom plate of the battery box 1, and a corresponding locking hole 10 is provided at the rear end of the locking connecting plate 9. After the battery box 1 is pushed into place, a locking screw (not shown in the figure, belonging to the existing mature structure) passes through the locking hole 10 and is locked in the locking threaded hole 8; it further ensures that the installation of the battery box is stable and reliable, and the structure is simple; in the specific embodiment, the locking threaded hole 8 is a through hole, and the locking hole 10 is a long slot hole, which ensures size adjustment with slight errors.

[0022] Its working principle is as follows: the battery box is transported to the battery box space of the new energy vehicle by an electric forklift. As long as the rollers at the bottom of the battery box are slightly aligned through the guide block, the battery box can be easily pushed in. Moreover, since the inner end surface of the guide block includes a front guide bevel, a middle guide plane, and a rear guide bevel, the battery box can be automatically guided and easily pushed in. The battery box will not shake left and right, front and back, or up and down, and the vibration during the operation of the new energy vehicle will not cause the battery box to loosen. Since at least one column hole is provided in the height direction of the front end stop rod of the slide rail seat, the bottom front end of the battery box is aligned with the guide block. A protruding post should be set at the corresponding position of the post hole. After the battery box is installed in place, the post is clamped in the post hole, and the post is tightly matched with the corresponding post hole. This design is because when the battery box is pushed into the position of the new energy bus battery box, we cannot fix it with our hands, so we will design the post and the post hole to fit tightly to ensure that the battery box is firmly fixed on the new energy vehicle body; in addition, after the battery box is pushed into place, the locking screw passes through the locking position and is locked in the locking threaded hole, so that the battery box can be easily and accurately positioned in the corresponding battery box space of the new energy vehicle, and the position of the battery box is firm and reliable.

[0023] The above is a detailed description of the specific embodiments of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
