Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to an electric truck battery frame and an electric truck battery assembly. Background Technology

[0002] In recent years, with the increasing awareness of global climate change and environmental protection, new energy vehicles have gradually become a hot area in the global automotive industry. Among them, electric trucks are playing an increasingly important role in urban logistics and urban construction. However, due to their limited driving range, the application of electric trucks in long-distance transportation and other fields has been restricted. To solve this problem, new energy heavy-duty truck technology centered on "battery swapping" has emerged in recent years.

[0003] The frame battery assembly is a new type of battery module. Compared with traditional battery modules, its biggest advantage lies in its ability to be quickly installed and removed. This feature makes the frame battery assembly an important component of battery swapping technology for electric trucks. Traditional electric trucks use integrated battery packs. When the battery pack fails or runs out of power, the entire battery pack needs to be replaced, requiring a long downtime and replacement period, which negatively impacts logistics and transportation efficiency. However, with the frame battery assembly, the battery pack can be divided into multiple modules, making the battery pack more flexible and allowing for partial replacement as needed. This shortens replacement time, improves battery swapping efficiency, and reduces transportation costs.

[0004] Existing frame battery assemblies still have some drawbacks. For example, when swapping batteries in electric trucks, the batteries need to be installed in designated locations on the electric trucks. These designated locations have connecting parts, and during battery swapping, these connecting parts need to be aligned one by one, making it difficult to install the batteries in the designated locations on the electric trucks. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an electric truck battery frame and an electric truck battery assembly to solve the problem mentioned in the background art that it is difficult to install the battery in the designated position of the electric truck during battery swapping.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An electric truck battery frame, comprising:

[0008] A frame, wherein at least one bracket is provided inside the frame, and the battery pack is disposed inside the bracket;

[0009] A base for supporting the frame, the frame being disposed at the upper end of the base in the height direction;

[0010] A limiting component includes a mounting plate, an elastic sheet, and a fixing plate. The mounting plate is fixedly disposed at the upper end of the base in the height direction and extends into the interior of the frame. The fixing plate is fixedly disposed at the lower end of the frame in the height direction. The mounting plate and the fixing plate are opposite to each other. The two ends of the elastic sheet are fixedly disposed on the side of the mounting plate in the height direction, and the middle part of the elastic sheet protrudes towards the fixing plate to form an arch shape. The protrusion of the elastic sheet is in close contact with the fixing plate.

[0011] Preferably, the limiting components are grouped in pairs, and the limiting components in the same group are perpendicular to each other.

[0012] Preferably, the mounting plate is located at a corner of the base.

[0013] Preferably, the mounting plate and the fixing plate are parallel to each other.

[0014] Preferably, a fixing angle iron is fixedly provided at the upper end of the base in the height direction.

[0015] Preferably, a connecting angle iron is fixedly provided at the lower end of the frame in the height direction corresponding to the fixed angle iron, and the fixed angle iron and the connecting angle iron are detachably connected.

[0016] Preferably, a mounting bracket is fixedly provided at the upper end of the base in the height direction, and a cooling water connector and a cable connector are provided at the upper end of the mounting bracket in the height direction.

[0017] Preferably, a guide rod is provided at the upper end of the mounting bracket in the height direction, and a guide hole is provided on the frame corresponding to the guide rod, with the guide rod extending into the guide hole.

[0018] Preferably, a support frame is fixedly provided at the lower end of the base in the height direction.

[0019] An electric truck battery assembly, including the electric truck battery frame.

[0020] In summary, this utility model has the following beneficial effects: By setting a limiting component, which includes a mounting plate, an elastic sheet, and a fixing plate, and with the elastic sheet located between the mounting plate and the fixing plate, when swapping batteries, the frame is moved onto the base. Since the limiting component is located at the upper end of the base in the height direction, and its upper end protrudes beyond the upper end of the base, only the frame needs to be moved to roughly align the mounting plate with the fixing plate. Due to the presence of the elastic sheet, which has a certain elasticity, a spring force is generated when the elastic sheet contacts the fixing plate. This not only limits the frame but also allows for some movement of the frame, adjusting its relative position and aligning the connecting parts. This solves the problem in the prior art where aligning the connecting parts one by one makes it difficult to install the battery in the designated position on the electric truck.

[0030] This utility model provides a battery frame for an electric truck.

[0031] Please see Figures 1-5 The electric truck battery frame provided by this utility model includes: a frame 1, with at least one bracket 101 disposed inside the frame 1, and a battery pack disposed inside the bracket 101; a base 2, which supports the frame 1, and the frame 1 is disposed at the upper end of the base 2 in the height direction; and a limiting component 3, which includes a mounting plate 301, an elastic piece 302, and a fixing plate 303. The mounting plate 301 is fixedly disposed at the upper end of the base 2 in the height direction and extends into the interior of the frame 1. The fixing plate 303 is fixedly disposed at the lower end of the frame 1 in the height direction, and the mounting plate 301 and the fixing plate 303 are opposite to each other. The two ends of the elastic piece 302 are fixedly disposed on the side of the mounting plate 301 in the height direction, and the middle part of the elastic piece 302 protrudes toward the fixing plate 303 to form an arch, and the protrusion of the elastic piece 302 is in close contact with the fixing plate 303.

[0032] The electric truck battery frame provided by this utility model features a limiting component 3, which includes a mounting plate 301, an elastic sheet 302, and a fixing plate 303. The elastic sheet 302 is located between the mounting plate 301 and the fixing plate 303. During battery swapping, the frame 1 is moved onto the base 2. Since the limiting component 3 is located at the upper end of the base 2 in the height direction, its upper end protrudes beyond the upper end of the base 2. At this time, it is only necessary to move the frame 1 to roughly align the mounting plate 301 with the fixing plate 303. Due to the presence of the elastic sheet 302, which has a certain elasticity, a spring force is generated when the elastic sheet 302 contacts the fixing plate 303. This not only limits the frame 1 but also allows for some movement of the frame 1, adjusting its relative position and aligning the connecting parts. This solves the problem in the prior art where it is difficult to install the battery in the designated position on the electric truck because each connecting part needs to be aligned individually.

[0033] See Figure 2 and Figure 5 In one embodiment of this utility model, the limiting components 3 are grouped in pairs, and the limiting components 3 in the same group are perpendicular to each other.

[0034] In this embodiment, since the lower end of the frame 1 and the upper end of the base 2 are usually rectangular, the limiting components 3 are arranged in pairs so that the limiting components 3 in the same group are perpendicular to each other, in order to accommodate the installation of the frame 1 with a rectangular bottom.

[0035] See Figure 2 and Figure 5 In one embodiment of this utility model, the mounting plate 301 is located at the corner of the base 2.

[0036] In this embodiment, since the lower end of the frame 1 and the upper end of the base 2 are usually rectangular, the mounting plate 301 is placed at the corner of the base 2, which can effectively limit the frame 1.

[0037] See Figure 4 In one embodiment of this utility model, the mounting plate 301 and the fixing plate 303 are parallel to each other.

[0038] In this embodiment, during the battery swapping process, the frame 1 moves onto the frame 2 and continues to move along the parallel mounting plate 301 and fixing plate 303, thus limiting the movement of the frame 1.

[0039] See Figure 2 In one embodiment of this utility model, a fixed angle iron 4 is fixedly provided at the upper end of the base 2 in the height direction.

[0040] In this embodiment, after installation, bolts can be installed on the fixed angle iron 4 to fix the frame 1.

[0041] See Figure 1 and Figure 4 In one embodiment of this utility model, a connecting angle iron 5 is fixedly provided at the lower end of the frame 1 in the height direction corresponding to the fixed angle iron 4, and the fixed angle iron 4 and the connecting angle iron 5 are detachably connected.

[0042] In this embodiment, the connecting angle iron 5 and the fixing angle iron 4 are provided with corresponding through holes. After installation, the bolts are inserted into the through holes and the nuts are tightened to complete the connection between the frame 1 and the base 2. At least two fixing angle irons 4 are provided on the long side of the base 2 and at least one fixing angle iron 4 is provided on the short side.

[0043] See Figure 2 In one embodiment of this utility model, a mounting bracket 6 is fixedly provided at the upper end of the base 2 in the height direction, and a cooling water connector 7 and a cable connector 8 are provided at the upper end of the mounting bracket 6 in the height direction.

[0044] In this embodiment, the frame 1 is equipped with a quick-connect coolant connector and a female cable connector corresponding to the coolant connector 7 and the cable connector 8. The cable connector 8 has the following model numbers: base 2 end: PFSC-KYA-BS3670, frame 2 end: PFSC-KYA-CP3670, manufacturer: Suzhou Ruikeda Connection System Co., Ltd. The coolant connector 7 has the following model numbers: DY131 / DY101, manufacturer: Ningbo Daya Auto Parts Co., Ltd.

[0045] See Figure 2 In one embodiment of this utility model, a guide rod 9 is provided at the upper end of the mounting bracket 6 in the height direction. The height of the guide rod 9 is less than the height of the limiting component 3 and greater than the height of the cooling water connector 7 and the cable connector 8. A guide hole is provided on the frame 1 corresponding to the guide rod 9, and the guide rod extends into the guide hole.

[0046] In this embodiment, four guide rods 9 are provided, all located at the middle of the upper part of the long side of the base 2. They can effectively limit the frame placed on the upper part of the base 2, preventing it from being misaligned and also preventing it from shaking.

[0047] See Figure 1 and Figure 2 In one embodiment of this utility model, a support frame 10 is fixedly provided at the lower end of the base 2 in the height direction.

[0048] In this embodiment, there are two support frames 10. The two support frames 10 are symmetrically arranged along the middle of the base 2. Each support frame includes a horizontal bar and two diagonal bars. The horizontal bar, the two diagonal bars and the base form a triangle. By utilizing the principle that triangles have high stability, the stability of the base 2 is improved and deformation of the base 2 is prevented.

[0049] This utility model also provides an electric truck battery assembly, including the electric truck battery frame described above. The specific structure of the electric truck battery frame is as described in the above embodiments. Since this electric truck battery frame adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
