This structure ensures stable installation between the connecting base and the crossbeam.

[0010] Preferably, a positioning observation hole is provided on the top of the crossbeam, and the bolt is placed inside the upper chamber through the positioning observation hole and locked in the threaded mounting hole. The above structure can facilitate the bolt installation between the second protrusion and the crossbeam.

[0011] Preferably, the first protrusion and the second protrusion are distributed in a stepped manner, and the end of the partition is placed inside the crossbeam. With the above structure, it is possible to ensure that the crossbeam can be sheathed outside the connecting seat.

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0019] like Figure 1 and Figure 2As shown, a limit bracket installation structure for a new energy battery box includes a battery box, the battery box has a vertically connected side beam 1 and a cross beam 2, a connecting seat 3 is installed on the side of the side beam 1, and the end of the cross beam 2 is fixedly mounted on the connecting seat 3. In this embodiment, a limit bracket 5 is installed on the upper side of the end of the cross beam 2, and the limit bracket 5 has a horizontal mounting section 5a and a limit section 5b extending vertically downward from one end of the horizontal mounting section 5a. The horizontal mounting section 5a is supported on the upper side area of ​​the cross beam 2 corresponding to the connecting seat 3, and the horizontal mounting section 5a, the cross beam 2 and the connecting seat 3 inside the cross beam 2 are locked together by bolts 4 penetrated from top to bottom. The limit section 5b is a block structure, and its two inner sides perpendicular to each other are respectively against the side of the side beam 1 and the cross beam 2.

[0020] With this design, the limiting bracket 5 is cleverly fixed to the upper side of the beam 2 with the help of bolts 4 and the connecting seat 3. Compared with the traditional welding fixing method, it greatly reduces the installation difficulty, speeds up the installation, and also saves welding costs.

[0021] In this embodiment, the limiting bracket 5 is made by a stamping process, and can also be mass-produced by a casting process, so that the installation accuracy of each limiting bracket 5 can be consistent.

[0022] like Figure 1 As shown, extensions 3a extend from both sides of the connecting base 3 along the length of the side beam 1. The extensions 3a are secured to the side beam 1 via screws 6. This ensures that the connecting base 3 can be stably mounted on the side of the side beam 1, thereby ensuring the stable installation of the crossbeam 2. In this embodiment, the extensions 3a on either side are secured to the side beam 1 via four screws 6. When the limiting bracket 5 is mounted on the crossbeam 2, one side of the limiting segment 5b can abut against the extension 3a of the connecting base 3.

[0023] like Figure 3 As shown, a partition 2a is formed inside the beam 2, and the partition 2a extends along the length direction of the beam 2. The partition 2a divides the interior of the beam 2 into an upper chamber 2b and a lower chamber 2c. The connecting seat 3 is respectively provided with a first protrusion 3b and a second protrusion 3c corresponding to the upper chamber 2b and the lower chamber 2c, and the top of the first protrusion 3b and the second protrusion 3c are both provided with a threaded mounting hole 3d. With such a design, the beam 2 can be further stably mounted on the connecting seat 3 by passing two bolts 4 between the beam 2 and the connecting seat 3 for fixing.

[0024] In this embodiment, the connecting seat 3 is integrally formed, the first protrusion 3b and the second protrusion 3c are distributed in a stepped manner, and the end of the partition 2a is formed inside the beam 2 to ensure that the second protrusion 3c can be inserted into the lower chamber 2c.

[0025] Furthermore, a positioning observation hole 2d is formed on the top of the crossbeam 2, and the bolt 4 is placed inside the upper chamber 2b through the positioning observation hole 2d and is used to connect the second protrusion 3c and the partition 2a.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
