[0019] A frame reinforcement plate matching structure and a box frame provided by an embodiment of the utility model are described in detail below in conjunction with the accompanying drawings.

Figure 1 to Figure 4As shown, a frame reinforcement plate matching structure provided by an embodiment of the utility model is suitable for structural reinforcement of a power battery frame tube beam structure to further improve the connection strength of the frame. The material of the frame tube beam is generally steel or aluminum alloy or other metals; the frame reinforcement plate matching structure provided by an embodiment of the utility model mainly includes: a tube beam crossbeam 1, a first vertical beam 2, a second vertical beam 3, and a reinforcement plate 4, wherein the first vertical beam 2 and the second vertical beam 3 are located on the upper and lower sides of the tube beam crossbeam 1 and are cross-connected with the tube beam crossbeam 1 by welding, and the reinforcement plate 4 is arranged at the cross-connection position of the first vertical beam 2, the second vertical beam 3 and the tube beam crossbeam 1 and are respectively welded to the first vertical beam 2, the second vertical beam 3, and the tube beam crossbeam 1 to realize frame structure reinforcement, which effectively increases the strength of the power battery frame tube beam structure and has better reliability and safety. More specifically, the reinforcement plate 4 is provided with a first flange 4-1 and a second flange 4-2, wherein the first flange 4-1 is limitedly fitted to the tube beam crossbeam 1 and connected by welding, and the first flange 4-1 effectively limits the position of the tube beam crossbeam 1, and at the same time increases the length of the weld, effectively enhancing the connection strength between the tube beam crossbeam 1 and the first vertical beam 2 and the second vertical beam 3 in the frame; wherein the second flange 4-2 is limitedly fitted to one of the first vertical beam 2 and the second vertical beam 3 and connected by welding, and the second flange 4-2 effectively limits the position of the first vertical beam 2 and / or the second vertical beam 3, and at the same time increases the length of the weld, effectively enhancing the connection strength between the tube beam crossbeam 1 and the first vertical beam 2 and the second vertical beam 3 in the frame. Of course, by changing the setting position of the first flange 4-1 on the reinforcing plate 4, the first flange 4-1 can also be limited and fitted with one of the first vertical beam 2 and the second vertical beam 3 and connected by welding. At this time, the corresponding second flange 4-2 is limited and fitted with the pipe beam cross beam 1 and connected by welding, which can achieve the same effect, and is not specifically limited here. It is worth noting that the reinforcing plate 4 can also be set to have a structural form of 3 or 4 flanges, and each flange is limited and fitted with one or more of the pipe beam cross beam 1, the first vertical beam 2, and the second vertical beam 3 at the corresponding position and welded.

[0021] In a frame reinforcement plate matching structure provided by an embodiment of the utility model, as a further improvement, the tube beam cross beam 1 is provided with a first opening 1-1 and a second opening 1-2, wherein the first opening 1-1 and the second opening 1-2 are respectively located on both sides of the tube beam cross beam 1, wherein the cross-sectional shape of the first vertical beam 2 is adapted to the first opening 1-1, so that the first vertical beam 2 is matched with the first opening 1-1 to achieve a matching connection, one end of the first vertical beam 2 extends into the first opening 1-1 and is mechanically connected to the tube beam cross beam 1 by welding, and the length of one end of the first vertical beam 2 extending into the first opening 1-1 is at least 1 cm, so as to ensure the necessary assembly length, and ensure To ensure the position constraint and positioning of the first vertical beam 2, the first vertical beam 2 and the first opening 1-1 are mechanically connected and fixed at the joint gap by circumferential welding. In this way, the first opening 1-1 can be used to position the first vertical beam 2 during welding, reducing the use of complex tooling, effectively ensuring the accuracy of its welding position, and reducing manufacturing costs. Compared with most of the direct butt welding of frames currently seen on the market, an auxiliary positioning structure of the first opening 1-1 on the tubular beam crossbeam 1 is added to ensure welding strength and accuracy, reduce welding stress concentration at the weld, improve the frame welding strength, and reduce weld cracking. Similarly, the cross-sectional shape of the second vertical beam 3 is adapted to the second opening 1-2, one end of the second vertical beam 3 extends into the second opening 1-2 and is mechanically connected to the tube beam cross beam 1 by welding, and the length of the second vertical beam 3 extending into the second opening 1-2 is at least 1 cm to ensure the necessary assembly length and to ensure the position constraint and positioning of the second vertical beam 3; the second vertical beam 3 and the second opening 1-2 are mechanically connected and fixed by circumferential welding at the joint gap, so that the second vertical beam 3 can be positioned when welded by the second opening 1-2, and the welding and positioning effects are as described in the first opening 1-1, and will not be repeated here. The tube beam cross beam 1 is generally a hollow structure, which reduces the weight while ensuring the necessary strength.

[0022] It is worth noting that the first vertical beam 2 and the second vertical beam 3 can also be the same vertical beam, or two vertical beams of the same or different specifications, which are not specifically limited here; the first opening 1-1 and the second opening 1-2 can be fully open or half open, as long as they can adapt to the shape of the corresponding vertical beam connected thereto and can achieve positioning.

[0023] On the other hand, the frame reinforcement plate matching structure provided by the embodiment of the utility model is not only applicable to the battery frame of new energy vehicles, but can also be applied to similar frame structures in other technical fields such as ships, aerospace, etc., and has a wide range of adaptability.

[0024] Some embodiments of the present application also provide a box frame, Figure 5The figure shows an overall three-dimensional structure diagram of a box frame provided by another embodiment of the utility model. The box frame can be used to accommodate power batteries or other products, wherein the box frame is provided with a frame reinforcement plate matching structure of the above embodiment. The frame reinforcement plate matching structure is adopted at multiple connection positions of the reinforcement plates 4, the tube beam cross beam 1 and the first vertical beam 2 and / or the second vertical beam 3 on multiple surfaces of the box frame, thereby greatly enhancing the overall strength of the box frame.

[0025] Compared with the prior art, in the frame reinforcement plate matching structure and the box frame provided by the embodiment of the utility model, the welding connection strength between the tube beam cross beam 1 and the vertical beam is improved by adaptive structural design improvement of the tube beam cross beam 1 and the reinforcement plate 4 with a flanging structure.
