[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0052] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0053] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0055] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0056] In related technologies, to meet the lightweight requirements of vehicle battery mounting structures, the size of the battery mounting structure is small, and the number of batteries installed is small, sometimes even just one battery. This results in a smaller battery capacity and a poorer driving range. Furthermore, the battery mounting structure in these technologies also makes the vehicle more prone to tilting, which is detrimental to safe driving.

[0057] Therefore, this application provides a battery frame structure 10 to solve one of the above-mentioned defects in battery fixing structures in the related art.

[0058] Figure 1 This is a schematic diagram of the battery frame structure in one embodiment of this application.

[0059] See Figure 1 The battery frame structure 10 includes three frame units 11 spaced apart along a first direction X, each frame unit 11 for mounting one battery. The battery frame structure 10 also includes at least two first connectors 12, wherein at least one first connector 12 connects two adjacent frame units 11 at one end along a second direction Y, and the other end is used to connect to one of the vehicle's longitudinal beams (not shown); wherein at least another first connector 12 connects two more adjacent frame units 11 at one end along the second direction Y, and the other end is used to connect to another longitudinal beam of the vehicle. The first direction X and the second direction Y are perpendicular to each other.

[0060] The aforementioned battery frame structure 10, by setting three frame units 11 spaced apart along the first direction X, and each frame unit 11 can install one battery, can increase the number of batteries, thereby increasing the overall battery capacity of the vehicle and improving the vehicle's range. By setting at least two first connectors 12, one end of the first connector 12 along the second direction Y is used to connect two adjacent frame units 11, and the other end is used to connect one of the vehicle's longitudinal beams, so that the battery frame structure 10 can be symmetrically arranged on the longitudinal beams, in order to improve the situation where the vehicle tilts due to the setting of the battery frame structure 10.

[0061] To facilitate a clear description of the technical solution of this application, the structure of the first connector 12 will be described in detail first, so as to clearly understand the specific connection relationship between the various structures.

[0062] Figure 2 This is a schematic diagram of the structure of the first connector in one embodiment of this application.

[0063] See Figure 2 and combined Figure 1In some embodiments, the first connector 12 includes a first connecting portion 121, a second connecting portion 122, and a third connecting portion 123. Specifically, the first connecting portion 121 extends along a second direction Y, with one end of the first connecting portion 121 connecting two adjacent frame units 11 along the second direction Y, and the other end used to connect to one of the longitudinal beams of the vehicle. The second connecting portion 122 is disposed on one side surface of the first connecting portion 121 along a first direction X, and the second connecting portion 122 connects to the first bracket 112 of one of the frame units 11. The third connecting portion 123 is disposed on the other side surface of the first connecting portion 121 along the first direction X, and the third connecting portion 123 connects to the first bracket 112 of the frame unit 11 adjacent to the frame unit 11 connected to the second connecting portion 122. That is, along the first direction X, the first connector 12 is located between two adjacent frame units 11, and the second connector 122 and the third connector 123 are provided on the surfaces of the first connector 121 on opposite sides along the first direction X, and respectively connect the first bracket 112 of the two adjacent frame units 11.

[0064] The first connecting part 121 has four first mounting holes b1 spaced apart at one end of the longitudinal beam. The longitudinal beam has mounting holes corresponding to the first mounting holes b1 one by one, and the first connecting part 121 and the longitudinal beam are connected by fasteners such as bolts (not shown in the figure). The second connecting part 122 has second mounting holes b2 spaced apart, and the first connecting part 121 also has two second mounting holes b2 spaced apart between the first mounting holes b1 and the second connecting part 122. The second connecting part 122 and a first bracket 112 of the corresponding frame unit 11 are connected by fasteners such as bolts. The third connecting part 123 has four third mounting holes b3 spaced apart, and the third connecting part and a first bracket 112 of the corresponding frame unit 11 are connected by fasteners such as bolts.

[0065] It is understood that the position and number of mounting holes in this application are set according to needs. Of course, the position and number of the first mounting hole b1, the second mounting hole b2 and the third mounting hole b3 are not limited to this application. In addition to fastener connection, other connection methods can also be used, and no further restrictions are imposed here.

[0066] Thus, by setting the first connector 12, which includes a first connecting part 121, a second connecting part 122 and a third connecting part 123, the first connector 12 can simultaneously connect the longitudinal beam and two adjacent frame units 11, making the connection method of the battery frame structure 10 simple, and the fastener connection also helps to improve the strength and stability of the battery frame structure 10.

[0067] It should be noted that the first connector 12 connects the longitudinal beam and the two adjacent frame units 11 by setting three connecting parts, rather than directly connecting the frame unit 11 and the longitudinal beam. This design is for two reasons: first, to adapt to the overall structure of the longitudinal beam, to avoid interference caused by direct connection between the frame unit 11 and the longitudinal beam as much as possible, and to facilitate the connection between the frame unit 11 and the longitudinal beam; second, by setting the first connector 12 to indirectly connect the frame unit 11 and the longitudinal beam, the first connector 12 acts as an intermediary. When either of the two adjacent frame units 11 and the longitudinal beam is subjected to force, the force will be transmitted to the first connector 12 first, thereby effectively reducing the force transmission to the other two structures. This is beneficial to improving the swaying of the battery frame structure 10 due to force, and further improving the strength and stability of the battery frame structure 10.

[0068] Figure 3 As shown in one embodiment of this application Figure 1 A partially enlarged schematic diagram of the first connector at point A in the middle; Figure 4 For this application Figure 3 A schematic diagram of the structure of the first connecting component.

[0069] See Figure 3 and Figure 4 and combined Figure 1 In some embodiments, a first connector 12 located at one end of frame unit 11 along the third direction Z (in conjunction with) Figure 1 (As described below, there are a total of eight first connecting members 12). At the end of the first connecting member 12 that connects to the longitudinal beam, a first clearance structure a1 and a second clearance structure a2 are respectively provided on opposite sides along the first direction X. The first clearance structure a1 and the second clearance structure a2 are used together to clear the traction seat connecting member of the longitudinal beam. The traction seat connecting member is used to connect the vehicle's cab and cargo box.

[0070] Continue reading Figure 1 , Figure 3 and Figure 4 In some embodiments, four first connectors 12 (combined with) are connected to two adjacent frame units 11. Figure 1 (As described below, there are a total of eight first connecting members 12). Each connecting member has a first clearance structure a1 and a second clearance structure a2 on opposite sides along the first direction X at one end connected to the longitudinal beam. The first clearance structure a1 and the second clearance structure a2 are used to clearance the traction seat connecting member of the longitudinal beam.

[0071] Continue reading Figure 1It is understood that the battery frame structure 10 has a total of eight first connectors 12, of which three first connectors 12 do not have a clearance structure, while the other five first connectors 12 have a first clearance structure a1 and a second clearance structure a2. Since the longitudinal beam has a traction seat connector, interference will occur between the first connecting part 121 and the traction seat connector when the battery frame structure 10 is installed. Therefore, a first clearance structure a1 and a second clearance structure a2 are provided on the corresponding first connecting part 121 to avoid the traction seat connector. For different types and models of vehicles, the specific structure of the longitudinal beam and the specific structure and position of the traction seat connector may be different. The shape and position of the clearance structure can be adjusted accordingly, and no further restrictions are imposed here.

[0072] Continue reading Figure 3 and Figure 4 In some embodiments, the first clearance structure a1 is configured as a notch on one side surface of the first connecting portion 121 along the first direction X, and the second clearance structure a2 is configured as a groove on the other side surface of the first connecting portion 121 along the first direction X, and the second clearance structure a2 is U-shaped. (Continue reading) Figure 1 The first clearance structure a1 connecting the first connection portion 121 of the first connector 12 connecting two adjacent frame units 11 and the first clearance structure a1 connecting the first connection portion 121 of another two adjacent frame units 11 are arranged opposite to each other.

[0073] Thus, by setting the first clearance structure a1 and the second clearance structure a2, the first connector 12 can be assembled with the longitudinal beam, thereby enabling the battery frame structure 10 to be installed and used normally.

[0074] Continue reading Figure 1 In some embodiments, the frame unit 11 includes a first mounting bracket 111 extending along a third direction Z and at least one first bracket 112. One surface of the first mounting bracket 111 along a second direction Y is used for mounting a battery, and all the first brackets 112 are spaced apart from the first mounting bracket 111 along the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0075] Thus, by setting the first mounting bracket 111 and the first bracket 112, it is convenient to install and support the battery. Furthermore, setting the first bracket 112 also helps to improve the strength of the frame unit 11 and supports the battery.

[0076] Figure 5 This is a schematic diagram of the structure of the first mounting bracket in one embodiment of this application; Figure 6 This is a schematic diagram of the structure of the first sub-part in one embodiment of this application; Figure 7 This is a schematic diagram of the structure of the second sub-part in one embodiment of this application.

[0077] See Figures 5 to 7 and combined Figure 1 In some embodiments, the first mounting bracket 111 includes two first sub-parts 1111 spaced apart along a first direction X. One end of the first bracket 112 is disposed in one of the first sub-parts 1111, and the other end is disposed in the other first sub-part 1111. The first mounting bracket 111 also includes at least two second sub-parts 1112 spaced apart along a third direction Z. One end of each second sub-part 1112 is disposed in one of the first sub-parts 1111, and the other end is disposed in the other first sub-part 1111. The battery is mounted on the first sub-parts 1111 and the second sub-parts 1112, and all the second sub-parts 1112 and all the first brackets 112 are spaced apart along a third direction Z.

[0078] Continue reading Figures 5 to 7 In some embodiments, both the first sub-part 1111 and the second sub-part 1112 are provided with a first threaded hole c1 and a second threaded hole c2, which are used to connect the battery mounting bracket. Because the battery is relatively heavy, it needs to be transferred to the battery frame structure 10 via the battery mounting bracket, and then the battery mounting bracket is removed after the battery is installed on the battery frame structure 10. Optionally, the first threaded hole c1 is the internal threaded hole of a nut welded into the frame unit 11, and the second threaded hole c2 is the internal threaded hole of a sleeve welded into the frame unit 11. It is understood that the specific formation method and number of the first threaded hole c1 and the second threaded hole c2 can be set as needed, and are not limited in detail here.

[0079] Figure 8 This is a schematic diagram of the structure of the first bracket in one embodiment of this application.

[0080] See Figure 8 and combined Figure 1 In some embodiments, along the first direction X, the first bracket 112 of the two frame units 11 located at both ends includes a first mounting portion 1121 and a second mounting portion 1122. The first mounting portion 1121 extends along the second direction Y, and one end of the first mounting portion 1121 is connected to a first connecting member 12 adjacent to the same first mounting bracket 111, that is, the first mounting portion 1121 is connected to the second connecting portion 122 of the first connecting member 12. The second mounting portion 1122 extends along the first direction X and is constructed in a "U" shape. One end of the second mounting portion 1122 along the first direction X is connected to the other end of the first mounting portion 1121, and the second mounting portion 1122 is disposed between the two first sub-parts 1111 of the same first mounting bracket 111. The connection between the first mounting portion 1121 and the second mounting portion 1122 is constructed as an arc connection.

[0081] Among them, see Figures 5 to 8 The second mounting portion 1122 of the first bracket 112 is provided with a plurality of sixth mounting holes b6 at intervals, and the first sub-part 1111 is provided with mounting holes (not shown in the figure) that correspond one-to-one with the sixth mounting holes b6. Fasteners such as bolts are inserted through the corresponding mounting holes to connect the first bracket 112 and the first sub-part 1111. It is understood that the position and number of the sixth mounting portions can be set as needed, and the first bracket 112 and the first sub-part 1111 can also be connected by other connection methods, and are not limited to this application.

[0082] Thus, by providing mounting holes and fasteners to connect the first bracket 112 and the first sub-part 1111, and by using fasteners as connectors, the strength and stability of the connection can be improved, thereby improving the overall strength and stability of the battery frame structure 10.

[0083] Figure 9 This is a schematic diagram of the structure of the first bracket in another embodiment of this application.

[0084] See Figure 9 and combined Figure 1 In some embodiments, along the first direction X, the first bracket 112 of the middle frame unit 11 extends along the first direction X. The first bracket 112 is disposed between two first sub-parts 1111 of the same first mounting bracket 111, and the first bracket 112 is also disposed between two first connectors 12 spaced apart along the first direction X. It can be understood that in this embodiment, the first bracket 112 is also provided with a sixth mounting hole b6, and the connection method is the same as the connection method of the first bracket 112 in the embodiments described above, so it will not be described again here; moreover, the first bracket 112 with different shapes and structures is also to accommodate the connection between different structures, and the specific shape and structure of the first bracket 112 can also be designed as needed, and is not limited thereto.

[0085] Continue reading Figure 1 In some embodiments, four first brackets 112 are provided, and all the first brackets 112 are arranged at equal intervals along the third direction Z. It is understood that the number of first brackets 112 can also be set as needed, and is not limited to four.

[0086] Thus, by setting multiple first brackets 112 to increase the contact surface with the battery, it is beneficial to improve the stability of the battery.

[0087] Continue reading Figure 1In some embodiments, eight first connectors 12 are provided. Four of the first connectors 12 are spaced apart along the third direction Z, and one end of each first connector 12 along the second direction Y connects to two adjacent frame units 11. The other four first connectors 12 are spaced apart along the third direction Z, and one end of each first connector 12 along the second direction Y connects to two other adjacent frame units 11. It is understood that the number of first connectors 12 can be set as needed, and is not limited to eight as in this application, and the specific shape of the first connectors 12 can also be designed as needed, without further limitation here.

[0088] Figure 10 This is a schematic diagram of the structure of the second connector in one embodiment of this application.

[0089] See Figure 10 And continue to refer to Figure 1 In some embodiments, six frame units 11 are provided, and all frame units 11 are arranged in a rectangular array of two rows and three columns. Each row has three frame units 11 spaced apart along the first direction X, and each column has two frame units 11 spaced apart along the second direction Y. The battery frame structure 10 also includes at least two second connectors 13, wherein at least one second connector 13 is connected at its opposite ends along the second direction Y to one first bracket 112 in each of the two rows of frame units 11 located at one end of the first direction X, and at least another second connector 13 is connected at its opposite ends along the second direction Y to one first bracket 112 in each of the two rows of frame units 11 located at the other end of the first direction X.

[0090] Thus, by setting up six frame units 11, the battery frame structure 10 can accommodate six batteries, thereby further increasing the number of batteries, increasing battery capacity, and thus improving the vehicle's range.

[0091] It should be noted that although adding frame units 11 can increase the number of batteries, the number of frame units 11 cannot be increased indefinitely due to the limited installation space of the vehicle. Moreover, when setting up the battery frame structure 10, the overall structure of the vehicle must be taken into account. Therefore, this application sets up six frame units 11 based on the actual situation.

[0092] Continue reading Figure 1 and Figure 10 The second connector 13 includes a connecting body 131 and two connecting structures 132 respectively located at opposite ends of the connecting body 131. The two connecting structures 132 respectively connect to one first bracket 112 in each of the two rows of frame units 11.

[0093] Thus, by setting the second connector 13, the two rows of frame units 11 are connected.

[0094] Continue reading Figure 1 In some embodiments, the first connector 12 further includes a fourth connecting portion 124 and a fifth connecting portion 125. The functions of the fourth connecting portion 124 and the fifth connecting portion 125 are exactly the same as those of the second connecting portion 122 and the third connecting portion 123. The fourth connecting portion 124 is provided with a fourth mounting hole b4 for connecting to the corresponding first bracket 112, and the fifth connecting portion 125 is provided with a fifth mounting hole b5 for connecting to the corresponding first bracket 112. Since the structure and connection method of the second connecting portion 122 and the third connecting portion 123 have been described in detail above, they will not be repeated here.

[0095] It should be noted that the specific shape and structure of the fourth connecting part 124 and the fifth connecting part 125, as well as the number and position of the mounting holes, can be set according to needs and are not limited to this application.

[0096] Continue reading Figure 1 In some embodiments, eight second connectors 13 are provided. Four of the second connectors 13 are spaced apart along the third direction Z and connect two rows of frame units 11 at one end along the first direction X; the other four second connectors 13 are spaced apart along the third direction Z and connect two rows of frame units 11 at the other end along the first direction X. That is, the second connectors 13 and the first brackets 112 are correspondingly provided. It can be understood that the second connectors 13 and the first brackets 112 may have corresponding mounting holes, and can be connected by fasteners such as bolts passing through the corresponding mounting holes. This connection method has been described in detail above, so it will not be repeated here; of course, the second connectors 13 and the first brackets 112 can also be connected by other connection methods, which are not limited here.

[0097] Thus, by setting multiple second connectors 13, it is beneficial to enhance the stability of the connection between the two rows of frame units 11.

[0098] Continue reading Figure 1 In this application, two rows of second connectors 13 are provided. Along the second direction Y, the row of second connectors 13 located upstream is mainly used to connect the working platform plate and the battery frame structure 10. The working platform plate is provided to connect other related structures and is not the battery frame structure 10 to be protected in this application, so it will not be described in detail here.

[0099] Figure 11 This is a schematic diagram of the structure of the first bracket in another embodiment of this application.

[0100] Combination Figure 1 , Figure 9 and Figure 11 , Figure 9 and Figure 11 The specific structure of the first bracket 112 is basically the same, the difference being that Figure 9 Excess mounting holes Figure 11 The mounting holes are mainly due to differences in the connection structure and position, and the specific shape and structure of the first bracket 112 and the mounting holes can also be customized as needed. Furthermore, along the second direction Y, Figure 9 The first bracket 112 is located in Figure 11 Downstream of the first bracket 112, that is, Figure 9 The first bracket 112 is located in the middle of the lower row of frame unit 11. Figure 11 The first bracket 112 is located in the middle of the upper row of frame unit 11.

[0101] This application also provides a vehicle including two longitudinal beams and the battery frame structure 10 described in any of the above embodiments. All first connectors 12 connected to two adjacent frame units 11 are connected at one end along a second direction Y to one of the longitudinal beams, and all first connectors 12 connected to the other two adjacent frame units 11 are connected at one end along the second direction Y to the other longitudinal beam.

[0102] In summary, because the battery mounting structure needs to meet certain strength and lightweight requirements, and the battery must be installed on the battery mounting structure, the limited space in the vehicle makes it difficult to arrange the battery mounting structure symmetrically on the vehicle. This leads to unbalanced forces on the vehicle, making it more prone to tilting. To improve this situation, this application provides a battery frame structure 10 and a vehicle, taking into account the vehicle's layout and structure. The battery frame structure 10 has six frame units 11 arranged in a rectangular array of two rows and three columns. A first connector 12 with five connecting parts connects the frame units 11 to the left and right longitudinal beams of the vehicle. Since the left and right longitudinal beams of the vehicle are symmetrically arranged, the first connecting part 121 connects to the longitudinal beams, and the other four connecting parts connect to the frame units 11. The specific shape, size, and mounting holes of each connecting part are designed to accommodate various loads. The structure adapted to the connection part allows the battery frame structure 10 to be symmetrically arranged on the vehicle; and the battery is also symmetrically mounted on the frame unit 11. This allows the battery frame structure 10 with the battery installed to be symmetrically arranged on the vehicle, so as to improve the situation where the vehicle tilts due to the installation of the battery frame structure 10; and when the vehicle is subjected to unbalanced forces due to uneven road surface or other conditions, the first connector 12, as a connector between the frame unit 11 and the longitudinal beam, can reduce the transmission of force between the frame unit 11 and the longitudinal beam, thereby helping to reduce the risk of vehicle tilting.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
