[0036] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0037] Combine the following Figure 1-Figure 4, describes the vibration tooling crossbeam provided in the embodiment of the present application, including a beam body 100 and a pressing portion 200, the pressing portion 200 is arranged on the beam body 100, and the pressing portion 200 is used to press against the beam body 100 along a preset direction, and the preset direction is the height direction of the beam body 100; at least part of the beam body 100 and / or the pressing portion 200 is a hollow structure 300. In some specific embodiments, the pressing portion 200 is welded to the beam body 100. The pressing portion 200 and the beam body 100 are integrally installed on the base of the vibration tooling, and the battery pack is arranged between the beam body 100 and the base of the vibration tooling, and the pressing portion 200 presses against the beam body 100 to press and fix the battery pack between the beam body 100 and the base of the vibration tooling.

[0038] By utilizing the technical solution of the above-mentioned embodiment of the present application, by providing the beam body 100 and the pressing portion 200, the pressing portion 200 can press against the beam body 100 along the height direction of the beam body 100. When the battery pack is installed between the vibration tooling base and the vibration tooling crossbeam, the pressing portion 200 can press against the beam body 100 to make the beam body 100 press against the battery pack, thereby ensuring that the battery pack can be firmly fixed on the vibration tooling and avoiding displacement or friction of the battery pack during the vibration test.

[0039] By designing at least part of the beam body 100 and / or the pressing part 200 as a hollow structure 300, the overall weight of the vibration tooling beam can be reduced to achieve lightweight. By combining the pressing part 200 with the hollow structure 300, the weight of the vibration tooling beam is effectively reduced while ensuring the strength of the vibration tooling beam, so that the battery pack can maintain installation reliability while reducing the risk of battery pack vibration failure.

[0040] Reference Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of the present application, the beam body 100 includes a substrate 110, a first vertical plate 120 and a second vertical plate 130, the substrate 110 has a first edge and a second edge arranged opposite to each other; the first vertical plate 120 is arranged at the first edge, and the first vertical plate 120 is vertically connected to the substrate 110; the second vertical plate 130 is arranged at the second edge, parallel to the first vertical plate 120, and the second vertical plate 130 is vertically connected to the substrate 110. In some specific embodiments, the substrate 110 is arranged horizontally, the first vertical plate 120 and the second vertical plate 130 are arranged vertically, the first vertical plate 120 is welded to the first edge of the substrate 110, and the second vertical plate 130 is welded to the second edge of the substrate 110. In this way, the space formed between the first vertical plate 120, the second vertical plate 130 and the substrate 110 is used to set the pressing part 200, and the pressing part 200 presses the beam body 100 to make the beam body 100 press against the battery pack, thereby ensuring that the battery pack can be firmly fixed on the vibration tooling.

[0041] Reference Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of the present application, the pressing portion 200 includes a pressing plate 210 and a third vertical plate 220, the pressing plate 210 is an arc-shaped plate bent toward the substrate 110, the pressing plate 210 is arranged between the first vertical plate 120 and the second vertical plate 130, and the opposite sides of the pressing plate 210 are respectively connected to the first vertical plate 120 and the second vertical plate 130; the third vertical plate 220 is arranged between the first vertical plate 120 and the second vertical plate 130, parallel to the first vertical plate 120, one end of the third vertical plate 220 is connected to the side of the pressing plate 210 close to the substrate 110, and the other end of the third vertical plate 220 is vertically connected to the substrate 110. In some specific embodiments, the pressing plate 210 is a steel plate that has been subjected to a press-bending process, and the pressing plate 210 is welded to the side surfaces of the first vertical plate 120 and the second vertical plate 130 that are arranged opposite to each other; the upper edge of the third vertical plate 220 is arc-shaped, and the pressing plate 210 is attached to the upper edge of the third vertical plate 220 after being pressed and bent, and the upper end of the pressing plate 210 is fixed to the upper edge of the third vertical plate 220 by welding, and the lower end of the pressing plate 210 is fixed to the base plate 110 by welding, and the pressing plate 210 that has a certain elastic deformation after being pressed and bent is fixed to the first vertical plate 120 and the second vertical plate 130, and The pressing plate 210 is connected to the substrate 110 through the third vertical plate 220. Due to the arc structure of the pressing plate 210 itself, the pressing plate 210 has a tendency to restore elastic deformation, that is, the two ends of the pressing plate 210 tend to open outward, and due to the welding limit, the middle part of the pressing plate 210 has downward pressure, so that the pressing plate 210 will press down the substrate 110 through the third vertical plate 220. When the battery pack is placed on the vibration fixture for vibration testing, the substrate 110 can press the battery pack tightly on the vibration fixture to ensure that the battery pack can be firmly fixed on the vibration fixture to avoid displacement or friction.

[0042] Reference Figure 1 As shown, in some embodiments of the present application, the length of the substrate 110 is greater than the length of the pressing portion 200. In some embodiments, the pressing portion 200 is disposed in the middle of the beam body, so both ends of the beam body protrude from the pressing portion 200. Specifically, the length of the substrate 110 is equal to the length of the first vertical plate 120 and the length of the second vertical plate 130, and the length of the pressing plate 210 is equal to the length of the third vertical plate 220, so both ends of the substrate 110 protrude from the pressing plate 210, thereby facilitating fixing the two ends of the substrate 110 on the base of the vibration tooling.

[0043] Specifically, mounting holes 111 are provided near both ends of the base plate 110 , and the base plate 110 is fixed to the base of the vibration tooling by bolts.

[0044] Reference Figure 1As shown, in some embodiments of the present application, the hollow structure 300 is a honeycomb structure. On the one hand, the honeycomb structure has a strong bearing capacity and can disperse the external forces from all directions, so that the honeycomb structure can withstand a large pressure from the battery pack; on the other hand, the honeycomb structure can reduce the weight of the vibration tooling because it has holes, and realize the lightweight design of the middle crossbeam of the vibration tooling.

[0045] Reference Figure 4 As shown, in some embodiments of the present application, at least one of the first vertical plate 120, the second vertical plate 130, and the third vertical plate 220 is provided with a honeycomb hole 310, the longitudinal section of the honeycomb hole 310 is a regular hexagon, and a plurality of honeycomb holes 310 form a honeycomb structure. Specifically, the honeycomb hole 310 is not provided at the edges of the first vertical plate 120, the second vertical plate 130, and the third vertical plate 220, so that the edges of the first vertical plate 120, the second vertical plate 130, and the third vertical plate 220 can be conveniently welded to the pressing plate 210, respectively, to ensure the strength of the welds.

[0046] Reference Figure 1 As shown, in some embodiments of the present application, the diameter of the honeycomb hole 310 is the diameter of the circumscribed circle of the regular hexagon, and the spacing between two adjacent honeycomb holes 310 is 1 / 4 of the diameter of the honeycomb hole 310. In this way, the honeycomb structure has high strength and rigidity, and can also reduce the overall weight of the vibration tooling.

[0047] In some specific embodiments, L is the total length of the vibration tooling beam, W is the total width of the vibration tooling beam, H is the total height of the vibration tooling beam, t is the thickness of the first vertical plate 120, the second vertical plate 130, the third vertical plate 220, the substrate 110, and the pressure plate 210; a is the distance from the edge of the honeycomb hole 310 to the edge of the third vertical plate 220, g is the distance from the end face of the third vertical plate 220 to the end face of the first vertical plate 120 or the second vertical plate 130; b is the distance from the edge of the honeycomb hole 310 to the substrate 110, c is the distance between two adjacent honeycomb holes 310, d is the diameter of the honeycomb hole 310, e is the height of the two ends of the first vertical plate 120 or the second vertical plate 130, and f is the distance between two adjacent mounting holes 111.

[0048] In the embodiment of the present application, the total length L of the vibration tooling beam is (1.2-1.3) × the width of the battery pack, the total width W of the vibration tooling beam is 0.1 × L, and the total height H of the vibration tooling beam is 1.5 × W; the diameter d of the honeycomb hole 310 is (1 / 10-1 / 5) × H, the spacing a = b = 0.5 × d, the spacing c between two adjacent honeycomb holes 310 is 0.25 × d, and the inner angle of the honeycomb hole 310 is 60°; the first vertical plate 120, the second vertical plate 130, the third vertical plate 220, the substrate 110, and the pressing plate 21 0's thickness t=0.5×d; the height of both ends of the first vertical plate 120 or the second vertical plate 130 is e=0.5×H. By decreasing the height of the first vertical plate 120 and the second vertical plate 130 along the length direction, the use of materials can be reduced while ensuring the strength of the tooling; the spacing between two adjacent mounting holes 111 is f=W / (4-6); the distance from the end face of the third vertical plate 220 to the end face of the first vertical plate 120 or the second vertical plate 130 is g=(0.05-0.1)×L, thereby facilitating the installation of the overall tooling and reducing the use of materials.
