It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0041] Combination Figures 1 to 4 As shown, according to a specific embodiment of the utility model, a power battery frame is provided.

[0042] Specifically, Figure 1 , Figure 2 As shown, a power battery frame comprises: a plurality of bracket assemblies 1, the plurality of bracket assemblies 1 are arranged at intervals, each bracket assembly 1 comprises a longitudinal beam portion 11 and a transverse beam portion 12, the longitudinal beam portion 11 is connected to one end of the transverse beam portion 12, the longitudinal beam portion 11 is connected to a vehicle frame 10, a power battery 100 is connected to the top of the transverse beam portion 12, the transverse beam portion 12 comprises a first support plate 121, an extension direction of the first support plate 121 is arranged at an angle to an extension direction of the longitudinal beam portion 11, and the first support plate 121 is fixedly connected to the bottom of the power battery 100 via a fixing member.

[0043] In this embodiment, multiple bracket assemblies 1 are arranged at intervals, and each bracket assembly 1 includes a longitudinal beam portion 11 and a cross beam portion 12. The cross beam portion 12 is used to support and connect the power battery, and only the bottom of the power battery is supported and fixed. This arrangement has a simple structure and occupies a small space. At the same time, the bracket assemblies 1 are arranged at intervals to evenly distribute the weight of the power battery 100, thereby improving the stability of the power battery. In addition, the connection method between the longitudinal beam portion 11 and the cross beam portion 12 can enhance the overall rigidity of the bracket assembly 1 and improve the stability and safety of the entire power battery frame. Therefore, this power battery frame has the advantages of simple structure, stability and reliability, and easy installation.

[0044] Furthermore, the cross beam 12 also includes at least two second support plates 122, which are respectively connected to both sides of the first support plate 121, and are arranged opposite to each other, and at least two second support plates 122 are extended along the height direction of the longitudinal beam 11. By setting the first support plate 121 and the at least two second support plates 122, the power battery can be effectively fixed to prevent shaking or falling off during driving, thereby ensuring the safety of the power battery. The overall structure is simple, the manufacturing cost is low, it is easy to install and maintain, and it has good practicality and economy.

[0045] like Figure 3 As shown, the longitudinal beam portion 11 includes: a first connecting plate 111, the first connecting plate 111 is connected to one end of the first supporting plate 121, and the first connecting plate 111 is arranged along the height direction of the frame 10; at least two second connecting plates 112, at least two second connecting plates 112 are respectively connected to the two sides of the first connecting plate 111, at least two second connecting plates 112 are arranged at an angle to the first connecting plate 111, and at least two second connecting plates 112 are arranged opposite to each other. Specifically, the connection method and angle setting of the longitudinal beam portion 11 and the cross beam portion 12 can make the bracket assembly 1 have better structural strength and stability, ensuring that the power battery will not loosen or fall off during the operation of the vehicle. On the whole, this power battery frame can effectively improve the performance and safety of the battery.

[0046] Furthermore, each second support plate 122 is provided with a notch 123 in the direction of the longitudinal beam portion 11, and the second support plate 122 is clamped with the second connecting plate 112 through the notch 123. Specifically, such a configuration can increase the stability and firmness of the connection, and can also reduce the amount of material used, thereby improving the overall performance of the structure. The provision of the notch 123 can make the second support plate 122 and the second connecting plate 112 more closely connected together, thereby increasing the bearing capacity and stability of the overall structure. At the same time, by reducing the amount of material used, the cost can also be reduced, thereby improving the economy of the structure.

[0047] Specifically, at least two second support plates 122 are provided with through slots 124, and the through slots 124 are triangular in shape. Providing the through slots 124 reduces the weight of the second support plates 122, further reduces the amount of material used, and can also reduce costs.

[0048] In this embodiment, the through slot 124 is configured as a triangular structure. In other embodiments, the structure of the through slot 124 is not limited thereto, and may also be circular, rectangular, square, etc.

[0049] Furthermore, the longitudinal beam portion 11 further includes: at least two third connecting plates 113, each of which is connected to each of the second connecting plates 112, and each of the third connecting plates 113 is arranged at an angle to each of the second connecting plates 112, and the third connecting plates 113 are connected to the vehicle frame 10. This arrangement enhances the stability of the longitudinal beam portion 11. By adding the third connecting plates 113, the stress on the longitudinal beam portion can be effectively dispersed, and local stress concentration can be reduced, thereby improving the load-bearing capacity and service life of the entire frame battery.

[0050] Specifically, a connecting hole is provided on the third connecting plate 113 , and the third connecting plate 113 is connected to the vehicle frame 10 through a fixing piece passing through the connecting hole.

[0051] Furthermore, each second connecting plate 112 is provided with a vacant portion 114, which is located below the third connecting plate 113 and is a curved surface structure. This arrangement is to enhance the stability and load-bearing capacity of the second connecting plate 112. The curved surface structure of the vacant portion 114 can effectively disperse the pressure, reduce the stress concentration of the longitudinal beam portion 11, and thus improve the overall performance and service life of the longitudinal beam portion 11. At the same time, the design of the vacant portion 114 can also reduce the weight of the longitudinal beam portion 11, save the layout space of the lower part of the frame 10, and reduce the cost.

[0052] Furthermore, each second connecting plate 112 is provided with a plurality of through holes 115, and the plurality of through holes 115 are arranged at intervals. The plurality of through holes 115 are used to reduce the weight of the battery frame and reduce the cost.

[0053] In this embodiment, the shape of the through hole 115 is circular. In other embodiments, the shape of the through hole 115 is not limited thereto, and may also be triangular, rectangular, or the like.

[0054] Further, the distance between at least two second support plates 122 is greater than the distance between at least two second connecting plates 112. By setting the distance between the second support plates 122 to be greater than the distance between the second connecting plates 112, at least two second support plates 122 can be snapped with the second connecting plates 112 through the notches 123, and at least two second support plates 122 can be snapped on the outside of at least two second connecting plates 112 and then further fixed by welding, so that the structure is simple, cost-saving, and no extra space is required.

[0055] like Figure 4 As shown, the first support plate 121 is tilted relative to the horizontal plane, and the cross section of the second support plate 122 is a triangular structure. This arrangement increases the stability and load-bearing capacity of the crossbeam 12. The tilted arrangement of the first support plate 121 can improve the anti-rolling ability of the first support plate 121, making it more stable. The triangular structure of the second support plate 122 can increase the load-bearing capacity of the first support plate 121, so that it can better support the pressure and weight of the power battery 100. Such technical effects can make the crossbeam 12 more reliable and safe in practical applications.

[0056] Furthermore, the upper structure of the longitudinal beam portion 11 is a "J"-shaped cross-section structure, which ensures that the frame structure has sufficient strength and rigidity in the vertical direction. The cross-section of the cross-beam portion 12 is U-shaped and the side is triangular. The triangular structure gives the cross-beam portion 12 sufficient rigidity and fixing strength.

[0057] In this embodiment, the bracket assembly 1 is provided in two groups. In other embodiments, the number of bracket assemblies 1 is not limited thereto. The number of groups can be adaptively adjusted according to the weight of the power battery and installation requirements. The power battery 100 can exceed the bracket assembly 1 and is not subject to the restrictions of a similar "outsourcing" structure.

[0058] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: while meeting the installation and fixation of the power battery of the hybrid light truck, the structure and related processes are simple, thus having the advantages of lightweight and low cost. With its simple structural characteristics, it is beneficial to expand its application in other adaptive vehicle models, greatly saving the development time of the power battery frame.

[0059] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0060] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in conjunction with any embodiment, it is claimed that the realization of such feature, structure or characteristic in conjunction with other embodiments also falls within the scope of the present utility model.
