"Inner, outer" refers to the inner and outer contours of the corresponding components, and in addition, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have sequentiality and importance.

[0061] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "arranged", "connected", "linked", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0062] As shown in Figures 1 to 7 The present disclosure provides a battery pack mounting bracket 100, which comprises a bracket body 10, the bracket body 10 is provided with a first mounting portion 30 and a second mounting portion 20, the first mounting portion 30 is used for connecting a battery pack 3000, and the second mounting portion 20 is used for connecting with a vehicle body main body 200, wherein the battery pack mounting bracket 100 and a battery pack mounting beam 201 on the vehicle body main body 200 are used together for mounting the battery pack 3000, that is, the battery pack mounting bracket 100 and the battery pack mounting beam 201 jointly serve as a mounting structure for mounting the battery pack 3000, and the battery pack 3000 is connected with the battery pack mounting bracket 100 and the battery pack mounting beam 201.

[0063] By the above technical solution, since the first mounting portion 30 on the support body 10 of the battery pack mounting support 100 can be used to connect the battery pack 3000, and the second mounting portion 20 on the support body 10 can be connected with the vehicle body main body 200, therefore, the battery pack mounting support 100 can be mounted on the vehicle body main body 200 and cooperates with the battery pack mounting beam 201 on the vehicle body main body 200 to jointly install a size of battery pack 3000 (for example, a battery pack 3000 with larger size and longer endurance mileage), while the battery pack mounting beam 201 itself can be used to install another size of battery pack 3000 (for example, a battery pack 3000 with smaller size and shorter endurance mileage), thereby allowing the battery pack mounting beam 201 to be used when installing battery packs 3000 of different sizes and endurance mileage, which is beneficial to improve the multiplicity of the battery pack mounting beam 201.

[0064] In addition, compared with the technical solution in the prior art that a separate mounting structure is arranged to install a size of battery pack 3000, since the battery pack mounting beam 201 can be used together with the battery pack mounting support 100 to install the battery pack 3000 and bear the load of the battery pack 3000, thereby allowing the size and volume of the battery pack mounting support 100 to be designed to be smaller than the mounting structure used to install the battery pack 3000 alone, that is, under the condition that the reliability of the connection between the battery pack 3000 and the vehicle body main body 200 is met, the size and volume of the battery pack mounting support 100 are designed to be smaller and the mass is lighter, thereby being beneficial to save cost and being beneficial to the lightweight of the vehicle body structure 2000.

[0065] As an embodiment, the battery pack mounting support 100 and the battery pack mounting beam 201 on the vehicle body main body 200 can be used together to install a first size of battery pack 3000 (as shown in Figure 5 The battery pack mounting beam 201 can be used to install a second size of battery pack 3000 different from the first size (as shown in Figure 3 .

[0066] It can be understood that the difference between the first size of battery pack 3000 and the second size of battery pack 3000 can be the difference in size along the front-rear direction of the vehicle body main body 200, can be the difference in size along the left-right direction of the vehicle body main body 200, or can be the difference in size along the front-rear direction of the vehicle body main body 200 and the difference in size along the left-right direction of the vehicle body main body 200, which is not limited in the present disclosure. For example, the second size of battery pack 3000 as shown in Figure 3 and the first size of battery pack 3000 as shown in Figure 5 , the difference between the two battery packs 3000 is the difference in size along the front-rear direction of the vehicle body main body 200.

[0067] Here, the first size can be greater than the second size, and the first size can also be smaller than the second size, and the present disclosure does not limit this. In an exemplary embodiment provided by the present disclosure, the length of the battery pack 3000 of the first size is greater than the length of the battery pack 3000 of the second size.

[0068] In the present disclosure, the second mounting portion 20 can be connected to the vehicle body main body 200 in any suitable manner, and can be fixedly connected (such as welding, riveting, etc.), or can be detachably connected, and the present disclosure does not limit this. As an embodiment of the present disclosure, the second mounting portion 20 can be detachably connected to the vehicle body main body 200.

[0069] Since the second mounting portion 20 can be detachably connected to the vehicle body main body 200, whether to install the battery pack mounting bracket 100 on the vehicle body main body 200 can be selected according to the size of the battery pack 3000, that is, whether to add a battery pack 3000 mounting point (i.e. the battery pack mounting bracket 100) on the vehicle body main body 200 in addition to the battery pack mounting beam 201 can be selected according to the size of the battery pack 3000.

[0070] For example, for a battery pack 3000 of a smaller size and shorter range (such as a battery pack 3000 of the second size), the battery pack mounting bracket 100 can not be installed on the vehicle body main body 200, and the battery pack 3000 can be installed through the battery pack mounting beam 201 on the vehicle body main body 200. For a battery pack 3000 of a larger size and longer range (such as a battery pack 3000 of the first size), the battery pack mounting bracket 100 can be installed on the vehicle body main body 200 to increase the mounting point of the battery pack 3000, and the battery pack 3000 can be installed through the battery pack mounting beam 201 and the battery pack mounting bracket 100.

[0071] That is, the battery pack mounting bracket 100 provided by the present disclosure can be selectively installed on the vehicle body main body 200, and used in cooperation with the battery pack mounting beam 201 when installed on the vehicle body main body 200, so that the battery pack mounting beam 201 can participate in the installation of battery packs 3000 of multiple sizes, thereby facilitating the improvement of the reuse rate of the battery pack mounting beam 201, and facilitating the reduction of unnecessary battery pack 3000 mounting members on the vehicle body main body 200 (such as when the vehicle body main body 200 needs to be configured with a battery pack 3000 of a smaller size, the battery pack mounting bracket 100 can not be installed on the vehicle body main body 200), thereby facilitating the lightweight of the vehicle body structure 2000.

[0072] Optionally, the above-mentioned battery pack mounting beam 201 and battery pack mounting bracket 100 can be arranged at the bottom of the vehicle body main body 200, such as below the floor of the vehicle 1000.

That is, the second threaded hole 31 can be configured by the nut 32 mounted on the bracket body 10, which is beneficial to the second threaded hole 31 having sufficient thread length on the one hand, and is beneficial to the second threaded hole 31 and the bracket body 10 having different physical properties respectively, so as to be beneficial to the bracket body 10 and the second threaded hole 31 having different advantages respectively, for example, it can be beneficial to the lightweight of the bracket body 10, and it is beneficial to the second threaded hole 31 having sufficient structural strength to avoid damage to the second threaded hole 31.

[0093] As another implementation, the second threaded hole 31 can be formed on the bracket body 10.

[0094] Optionally, the hardness of the nut 32 can be greater than the hardness of the bracket body 10. In this way, the second threaded hole 31 on the nut 32 has sufficient structural strength, thereby avoiding the situation that the threads of the second threaded hole 31 are damaged, causing the second fastener to slip, unable to be disassembled, and the like. Moreover, the material of the bracket body 10 can be made of a material with lighter quality, thereby facilitating the lightening of the battery pack mounting bracket 100. For example, the nut 32 can be made of steel, and the bracket body 10 can be made of aluminum.

[0095] In order to facilitate the connection of the second fastener and the second threaded hole 31, as an implementation, the nut 32 is movably installed on the bracket body 10. When connecting the battery pack 3000 and the second threaded hole 31, the position of the second threaded hole 31 can be changed by moving the nut 32, eliminating the tolerances of each component itself and the assembly tolerances, thereby ensuring that the second threaded hole 31 can be aligned with the second fastener on the battery pack 3000 and connected, not only facilitating the reduction of the connection difficulty of the second fastener and the second threaded hole 31, but also facilitating the guarantee of the installation accuracy of the battery pack 3000.

[0096] Here, the nut 32 can be directly movably connected with the bracket body 10, or indirectly movably connected with the bracket body 10 through other structures, which is not limited in the present disclosure. In an exemplary implementation provided by the present disclosure, as shown in Figure 1 The first mounting portion 30 further includes a sliding member 33, the nut 32 is installed on the sliding member 33, the bracket body 10 has a first sliding portion 41, the sliding member 33 has a second sliding portion 42, the first sliding portion 41 and the second sliding portion 42 are in sliding cooperation, so that the nut 32 can be driven to slide when the sliding member 33 slides, thereby adjusting the position of the second threaded hole 31.

[0097] Optionally, the sliding member 33 can be formed in a plate shape, and the plate-shaped sliding member 33 and the nut 32 together constitute a nut 32 plate.

[0098] The present disclosure does not limit the specific position of the first sliding portion 41 on the bracket body 10, the specific position of the second sliding portion 42 on the sliding member 33, the specific shape of the first sliding portion 41 and the second sliding portion 42, and the specific number of the first sliding portion 41 and the second sliding portion 42. For example, one of the first sliding portion 41 and the second sliding portion 42 can be a sliding groove, and the other of the first sliding portion 41 and the second sliding portion 42 can be a sliding block.

[0099] In an example embodiment provided in the present disclosure, the first sliding part 41 comprises a first sliding groove 15 and a second sliding groove 16, the first sliding groove 15 and the second sliding groove 16 are oppositely arranged, the sliding member 33 is provided with a second sliding part 42 on both sides, and the second sliding parts 42 on both sides of the sliding member 33 are respectively in sliding cooperation with the first sliding groove 15 and the second sliding groove 16. Since the second sliding parts 42 on both sides of the sliding member 33 are respectively in sliding cooperation with the first sliding groove 15 and the second sliding groove 16, the stability of the movement of the sliding member 33 can be improved. It can be understood that, when the second fastener is connected with the second threaded hole 31, the sliding member 33 can move axially along the second threaded hole 31, so as to abut against the groove walls of the first sliding groove 15 and the second sliding groove 16, and the nut 32 is fixed to the bracket body 10.

[0100] Optionally, the bracket body 10 is provided with an avoiding opening 17, the avoiding opening 17 is located between the first sliding groove 15 and the second sliding groove 16, and the nut 32 is movably located in the avoiding opening 17. Since the two sides of the sliding member 33 are respectively in sliding cooperation with the first sliding groove 15 and the second sliding groove 16, and the nut 32 is movably located in the avoiding opening 17, the nut 32 installed on the sliding member 33 can move in the avoiding opening 17 along the extension direction of the first sliding groove 15 and the second sliding groove 16.

[0101] In order to facilitate the disassembly and assembly between the sliding member 33 and the bracket body 10, as an example, as shown in Figure 1 , one end of the first sliding groove 15 is a first open end 151, one end of the second sliding groove 16 is a second open end 161, and the first open end 151 and the second open end 161 are used for inserting the second sliding parts 42 on both sides of the sliding member 33 into the first sliding groove 15 and the second sliding groove 16.

[0102] Since the sliding member 33 can be inserted into the first sliding groove 15 and the second sliding groove 16 through the first open end 151 and the second open end 161, the sliding member 33 and the nut 32 can be machined with the bracket body 10 respectively, and then assembled, so as to facilitate to reduce the machining difficulty of the battery pack mounting bracket 100, and when the nut 32 and the sliding member 33 are damaged, the nut 32 and the sliding member 33 can be replaced separately.

[0103] Optionally, as shown in Figure 7 , the bracket body 10 is formed with a through hole 18, the through hole 18 is used for passing the second fastener to be connected with the second threaded hole 31, and the hole diameter of the through hole 18 is greater than the hole diameter of the second threaded hole 31.

[0104] Since the second fastener can pass through the through hole 18 and be connected with the second threaded hole 31, when the second fastener is screwed, the battery pack 3000 and the nut 32 can jointly clamp the bracket body 10, so as to realize the fixation of the nut 32 on the bracket body 10. Moreover, since the diameter of the through hole 18 is larger than the diameter of the second threaded hole 31, even if the axis of the through hole 18 is not opposite to the axis of the second threaded hole 31, the connection of the second fastener with the second threaded hole 31 will not be hindered, so as to play a role in absorbing tolerance and facilitate the reduction of the machining precision requirement of the corresponding components.

[0105] The material of the bracket body 10 is not limited in the present disclosure, and as an embodiment, the bracket body 10 can be made of aluminum. The bracket body 10 made of aluminum can have a lighter weight on the one hand, thereby facilitating the lightweight of the vehicle body main body 200 provided with the bracket body 10, and on the other hand, the bracket body 10 can have good corrosion resistance, avoiding the problem of insufficient strength of the battery pack 3000 mounting point caused by part corrosion.

[0106] Alternatively, the bracket body 10 can be made of cast aluminum A380, so that the bracket body 10 has a lighter weight and good corrosion resistance.

[0107] In the present disclosure, the bracket body 10 can be provided with any suitable thickness, which is not limited in the present disclosure, and as an embodiment, the thickness of the bracket body 10 can be greater than or equal to 3 mm, for example, the thickness of the bracket body 10 can be 5 mm. The thickness of the bracket body 10 meets the above range, which is advantageous to ensure that the bracket has sufficient rigidity and strength, and avoid the shaking of the battery pack 3000 after installation.

[0108] According to a second aspect of the present disclosure, a vehicle body structure 2000 is provided, comprising a vehicle body main body 200, a battery pack mounting beam 201 and the above-mentioned battery pack mounting bracket 100, the battery pack mounting beam 201 and the battery pack mounting bracket 100 are both connected to the vehicle body main body 200, wherein the battery pack mounting bracket 100 and the battery pack mounting beam 201 on the vehicle body main body 200 are used together to install the battery pack 3000.

[0109] Since the vehicle body main body 200 of the vehicle body structure 2000 is provided with both the battery pack mounting beam 201 and the battery pack mounting bracket 100, the vehicle body main body 200 can jointly install, for example, a battery pack 3000 with a larger size (for example, a battery pack 3000 with a first size) through the battery pack mounting bracket 100 and the battery pack mounting beam 201, and can also separately install, for example, a battery pack 3000 with a smaller size (for example, a battery pack 3000 with a second size) through the battery pack mounting beam 201.

[0110] According to a third aspect of the present disclosure, there is provided a vehicle body structure comprising a vehicle body main body 200 and a battery pack mounting beam 201 provided on the vehicle body main body 200, the vehicle body main body 200 being configured to be capable of accommodating the battery pack mounting bracket 100 described above, wherein the battery pack mounting bracket 100 and the battery pack mounting beam 201 on the vehicle body main body 200 are used in common to mount the battery pack 3000. In this vehicle body structure, the battery pack mounting bracket 100 is not included, and the vehicle body main body 200 is only required to be capable of accommodating the battery pack mounting bracket 100, i.e., the vehicle body main body 200 can provide a mounting region, a mounting point, or a mounting position for mounting the battery pack mounting bracket 100, so that the battery pack mounting bracket 100 can be subsequently mounted to the vehicle body main body 200.

[0111] Since the vehicle body main body 200 of this vehicle body structure 2000 is provided with the battery pack mounting beam 201 and is configured to be capable of accommodating the battery pack mounting bracket 100 described above, when a battery pack 3000 of a small size (e.g., a battery pack of the second size) is required to be arranged, the vehicle body main body 200 can be selected not to be provided with the battery pack mounting bracket 100, and only the battery pack mounting beam 201 is used to mount the battery pack 3000 of a small size, so that the lightweight of the vehicle body main body 200 can be improved. When a battery pack 3000 of a large size (e.g., a battery pack of the first size) is required to be arranged, the battery pack mounting bracket 100 can be selected to be mounted to the vehicle body main body 200, so that the vehicle body main body 200 has the capability of mounting the battery pack 3000 of a large size.

[0112] The present disclosure does not limit the connection manner of the battery pack mounting beam 201 to the vehicle body main body 200 and the battery pack 3000, for example, the battery pack mounting beam 201 can be fixed (e.g., by welding) to the vehicle body main body 200 and connected to the battery pack 3000 by fasteners, or the battery pack 3000 can be detachably connected to the vehicle body main body 200 and connected to the battery pack 3000 by fasteners.

[0113] The present disclosure does not limit the arrangement manner of the battery pack mounting bracket 100 and the battery pack mounting beam 201 on the vehicle body main body 200, and as an embodiment, as shown in FIG. 2, the battery pack mounting beam 201 and the battery pack mounting bracket 100 can be arranged in a spaced manner along the front-rear direction of the vehicle body main body 200. In this way, the battery pack mounting bracket 100 and the battery pack mounting beam 201 can be used in common to mount a battery pack 3000 of a length in the front-rear direction of the vehicle body main body 200 (e.g., a battery pack of the first size as shown in FIG. 3). Figure 2 Figure 5

[0114] ​​As another implementation, the battery pack mounting bracket 100 and the battery pack mounting beam 201 can also be arranged in a left-right direction of the vehicle body main body 200, thereby facilitating the battery pack mounting bracket 100 and the battery pack mounting beam 201 to jointly mount the battery pack 3000 with a wider width in the left-right direction of the vehicle body main body 200.

[0115] In order to facilitate the connection of the battery pack mounting bracket 100 and the vehicle body main body 200, as an implementation, as shown in Figure 4 and Figure 6 , the vehicle body main body 200 can be provided with a bracket connecting portion 202, which is used to connect with the second mounting portion 20 of the battery pack mounting bracket 100. Here, the bracket connecting portion 202 can be a connecting surface (such as a welding surface) for connecting with the second mounting portion 20, or a connecting structure (such as the first threaded hole 2021, the stud 2022, a clamping groove, a clamping block, etc.) for connecting with the second mounting portion 20, which is not limited in the present disclosure.

[0116] By providing the bracket connecting portion 202 on the vehicle body main body 200, when the battery pack mounting bracket 100 is mounted on the vehicle body main body 200, the positioning time of the battery pack mounting bracket 100 on the vehicle body main body 200 can be shortened, and the positioning accuracy of the battery pack mounting bracket 100 on the vehicle body main body 200 can be improved, thereby improving the efficiency of the battery pack mounting bracket 100 mounted on the vehicle body main body 200, and improving the reliability of the vehicle body main body 200 mounting the battery pack 3000 through the battery pack mounting bracket 100.

[0117] The present disclosure does not limit the connection mode of the bracket connecting portion 202 and the second mounting portion 20, and as an implementation, the bracket connecting portion 202 and the second mounting portion 20 can be detachably connected, thereby facilitating the selective installation of the battery pack mounting bracket 100 on the vehicle body main body 200. For example, the bracket connecting portion 202 can include the first threaded hole 2021 and the stud 2022 provided on the vehicle body main body 200 as mentioned above, thereby cooperating with the first fastener and the mounting hole on the bracket body 10 to achieve detachable connection of the bracket connecting portion 202 and the second mounting portion 20.

[0118] As another implementation, the bracket connecting portion 202 can also be connected with the second mounting portion 20 by welding.

[0119] Optionally, as shown in Figure 3 and Figure 4 , the bracket connecting portion 202 and the battery pack mounting beam 201 are arranged in a front-rear direction of the vehicle body main body 200. In this way, the battery pack mounting bracket 100 connected to the bracket connecting portion 202 can be arranged in the front-rear direction of the vehicle body main body 200.

[0120] The present disclosure does not limit the specific position of the bracket connecting portion 202 on the vehicle body main body 200, and as an embodiment, as shown in Figures 2 to 7 The vehicle body structure 2000 includes longitudinal beams 203, and the bracket connecting portion 202 can be arranged on the longitudinal beams 203. Since the longitudinal beams 203 have good rigidity and strength, arranging the bracket connecting portion 202 on the longitudinal beams 203 is beneficial to improve the connection reliability of the battery pack mounting bracket 100 and the vehicle body main body 200.

[0121] Alternatively, the above-mentioned longitudinal beams 203 can be front floor longitudinal beams 203, rear floor longitudinal beams 203, or middle floor longitudinal beams 203, and the present disclosure does not limit this.

[0122] Alternatively, as shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the vehicle body main body 200 has a recessed space 204, the battery pack mounting beam 201 is arranged outside the recessed space 204, and the bracket connecting portion 202 is located in the recessed space 204. By arranging in this way, at least part of the battery pack mounting bracket 100 can be accommodated in the recessed space 204, thereby avoiding the battery pack mounting bracket 100 from extending downward too much, which affects the installation position of the battery pack 3000.

[0123] In addition, due to the limitation of the recessed space 204, the length of the battery pack mounting beam 201 cannot be further extended, thereby limiting the size of the battery pack 3000 that can be installed by the battery pack mounting beam 201, and the battery pack mounting bracket 100 provided by the present disclosure can be installed in the recessed space 204, thereby through the joint use of the battery pack mounting bracket 100 and the battery pack mounting beam 201, it is beneficial to install a larger size battery pack 3000 on the vehicle body main body 200, thereby improving the endurance of the vehicle 1000.

[0124] Here, the recessed space 204 can be located between two longitudinal beams 203 arranged along the left-right direction of the vehicle body main body 200.

[0125] Alternatively, the above-mentioned recessed space 204 can be an accommodation space for accommodating the fuel tank of the vehicle 1000.

[0126] The present disclosure does not limit the structure of the bracket connecting portion 202, and alternatively, as shown in Figure 6 , the bracket connecting portion 202 can include a first threaded hole 2021 and / or a stud 2022.

[0127] For example, the bracket connecting portion 202 can include one first threaded hole 2021 and at least two threaded studs 2022, the first fastener can pass through the first mounting hole 211 and be connected with the first threaded hole 2021, and the at least two threaded studs 2022 can pass through the corresponding second mounting holes 212 respectively.

[0128] Optionally, the vehicle body main body 200 can be provided with a projection welding nut, and the projection welding nut has a first threaded hole 2021. In addition, the at least two threaded studs 2022 can be projection welding studs 2022 provided on the vehicle body main body 200.

[0129] In the present disclosure, whether the battery pack mounting bracket 100 is installed on the vehicle body main body 200 can be selected according to the size of the battery pack 3000. As an embodiment, the vehicle body structure 2000 can include the above-mentioned battery pack mounting bracket 100, so that the vehicle body structure 2000 has the ability to install a larger size battery pack 3000.

[0130] Optionally, as shown in Figure 1 The size of the battery pack mounting beam 201 in the front-rear direction of the vehicle body main body 200 can be greater than the size of the battery pack mounting bracket 100 in the front-rear direction of the vehicle body main body 200. In this way, a larger part of the weight of the battery pack 3000 can be borne by the battery pack mounting beam 201 fixedly connected with the vehicle body main body 200, and a smaller part of the weight of the battery pack 3000 can be borne by the battery pack mounting bracket 100 detachably connected with the vehicle body main body 200, thereby facilitating to ensure the connection reliability of the battery pack 3000 and the vehicle body main body 200.
