[0024] This application provides a battery frame 1, which is used in a battery case 2 in practical applications. The battery frame 1 of this application will be described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-15 This application provides a battery frame 1, which includes: a main frame 11, the main frame 11 including a first side 111 and a second side 112 disposed opposite to each other along a first direction Z; and a first bracket 12, the first bracket 12 being connected to the main frame 11 and disposed close to the second side 112; wherein, the first bracket 12 is provided with a forklift hole 121 on one side along a second direction X, the forklift hole 121 penetrating the first bracket 12 along the second direction X, the forklift hole 121 being used to cooperate with the forks of the battery swapping equipment to pick up the battery frame 1, the first direction Z being the height direction of the battery frame 1, and the second direction X being perpendicular to the first direction Z.

[0026] Specifically, the first direction Z is as follows Figure 1 The Z-axis direction is shown, and the second direction X is as follows: Figure 1 The X-axis direction is shown, where the first direction Z is the height direction of the battery frame 1, and the second direction X is the length direction of the battery frame 1. The first direction Z and the second direction X are perpendicular to each other.

[0027] The main frame 11 is a cuboid main frame structure. The main frame 11 is composed of several rectangular tubes connected together. The main frame 11 is used to install multiple battery packs 23 of the battery box 2. The material of the main frame 11 can be 700 high-strength steel, which has high strength and light weight, so as to reduce the weight of the main frame 11 to the minimum while improving the strength of the main frame 11.

[0028] The first bracket 12 is also a rectangular frame structure composed of several rectangular tubes connected together. The dimensions of the first bracket 12 correspond to those of the main frame 11. The first bracket 12 is used to install the thermal management unit 24 and control box 25 of the battery module. The material of the first bracket 12 can also be 700 high-strength steel, which is high in strength and light in weight, so as to improve the strength of the first bracket 12 while minimizing its overall weight.

[0029] Both the main frame 11 and the first support 12 are made of 700 high-strength steel, which can improve the overall strength of the battery frame 1 while reducing the overall weight of the battery frame 1.

[0030] The main frame 11 includes a first side 111 and a second side 112 arranged opposite to each other along the first direction Z, wherein the first side 111 is the bottom of the main frame 11, the second side 112 is the top of the main frame 11, a first bracket 12 is arranged close to the second side 112, and the first bracket 12 is connected to the main frame 11.

[0031] The first bracket 12 is provided with a forklift hole 121 on one side along the second direction X. The forklift hole 121 penetrates the first bracket 12 along the second direction X. The cross-section of the forklift hole 121 can be any shape such as rectangle or circle. The size of the forklift hole 121 is larger than the size of the forks of the battery swapping equipment. When it is necessary to disassemble or assemble the battery frame 1, the forks of the battery swapping equipment are inserted into the forklift hole 121 from the side of the first bracket 12 along the second direction X along the second direction X. The battery replacement operation of the battery box 2 on the vehicle 3 is realized by the battery swapping equipment picking up the battery frame 1.

[0032] In this embodiment, the battery frame 1 includes a main frame 11 and a first bracket 12. A forklift hole 121 is provided on one side of the first bracket 12 along the second direction X. The forklift hole 121 penetrates the first bracket 12 along the second direction X. Thus, when the battery box 2 needs to be replaced, the battery swapping device can be inserted into the forklift hole 121 from the side of the main frame 11 along the second direction X. That is, the battery swapping device can pick up the battery box 2 from the side of the battery frame 1 along the second direction X, thereby increasing the contact area between the battery swapping device and the battery frame 1. This can improve the stability of the battery box 2 during replacement and reduce the occurrence of problems such as the battery box 2 being bumped.

[0033] Optionally, there are at least two forklift holes 121, and at least two forklift holes 121 are spaced apart along a third direction Y on the first bracket 12, with the third direction Y being perpendicular to the first direction Z and the second direction X.

[0034] Specifically, the third party to Y is as follows: Figure 1 The Y-axis direction shown is the width direction of the battery frame 1. The third direction Y, the first direction Z, and the second direction X are perpendicular to each other.

[0035] There can be at least two forklift holes 121, which are spaced apart along a third direction Y on the first bracket 12. Correspondingly, there are also at least two forks in the power swapping equipment, with one fork inserted into one forklift hole 121. For example, as shown... Figures 1-3 As shown, there are two forklift holes 121, which are respectively located on both sides of the first bracket 12 along the third direction Y.

[0036] In practical applications, by setting at least two forklift holes 121, when the battery box 2 needs to be replaced, at least two forks of the battery swapping device can be inserted into at least two forklift holes 121 from the side of the main frame 11 along the second direction X, which further increases the contact area between the battery swapping device and the battery frame 1, thereby further improving the stability of the battery box 2 during replacement and reducing the occurrence of problems such as the battery box 2 being bumped.

[0037] Optionally, the first bracket 12 is disposed at the lower part of the second side 112 along the first direction Z, and the first bracket 12 is fixedly connected to the inside of the main frame 11, and the forklift hole 121 is located inside the main frame 11.

[0038] Specifically, such as Figure 1 As shown, the first bracket 12 is located at the lower part of the second side 112 of the main frame 11, and the first bracket 12 is welded to the inside of the main frame 11. That is, the first bracket 12 is located in the internal space of the top of the main frame 11 along the first direction Z. At this time, the forklift hole 121 is located inside the main frame 11. In this way, the first bracket 12 does not need to occupy the extra space outside the main frame 11, reducing the size of the battery box 2, thereby reducing the installation space of the vehicle 3 occupied by the battery box 2 and improving the space utilization rate.

[0039] Optionally, the first bracket 12 is disposed on the upper part of the second side 112 along the first direction Z and is fixedly connected to the second side 112, and the forklift hole 121 is located outside the main frame 11.

[0040] like Figures 4-5 As shown, the first bracket 12 is located at the top of the second side 112 along the first direction Z, and the bottom surface of the first bracket 12 along the first direction Z is welded to the second side 112. That is, the first bracket 12 is located on the top surface of the main frame 11 along the first direction Z. At this time, the forklift hole 121 is located outside the main frame 11. In this way, when replacing the battery box 2, since the forklift hole 121 is located outside the main frame 11, the forklift space of the battery swapping equipment is larger and the operation is easier.

[0041] Optionally, it also includes two X-shaped reinforcing brackets 13, which are fixedly connected to the main frame 11, and the two reinforcing brackets 13 are respectively disposed inside the main frame 11 on both sides along the second direction X.

[0042] like Figure 1 and Figure 7As shown, the reinforcing bracket 13 consists of two reinforcing rods arranged in a cross shape, making the reinforcing bracket 13 X-shaped. One reinforcing bracket 13 is located inside the left side of the main frame 11 along the second direction X, and the other reinforcing bracket 13 is located inside the right side of the main frame 11 along the second direction X. The ends of the two reinforcing brackets 13 are welded to the main frame 11. The reinforcing bracket 13 can also be made of 700 high-strength steel.

[0043] In this embodiment, reinforcing brackets 13 are fixedly connected to both sides of the main frame 11 along the second direction X. The reinforcing brackets 13 can strengthen the main frame 11, improve the overall rigidity and strength of the main frame 11, and extend the service life of the battery frame 1.

[0044] Optionally, it also includes a skin 14, which is fixedly connected to the outer surface of the main frame 11, or the skin 14 covers the outer surfaces of the main frame 11 and the first support 12.

[0045] Specifically, such as Figures 8-11 As shown, the skin 14 is connected to the outer periphery of the main frame 11 by fasteners, or, as... Figure 4 and Figure 6 As shown, the skin 14 is connected to the outer periphery of the main frame 11 and the first bracket 12 by fasteners. The skin 14 has a small thickness; for example, the thickness of the skin 14 can be 1 mm. The material of the skin 14 can be Q235A, SPCC, glass fiber composite material, etc.

[0046] The skin 14 may include a first skin 141, a second skin 142, a third skin 143, and a fourth skin 144. The first skin 141 and the second skin 142 have the same size and are respectively disposed on both sides of the main frame 11 along the second direction X. The third skin 143 and the fourth skin 144 have the same size and are respectively disposed on both sides of the main frame 11 along the third direction Y.

[0047] In practical applications, by providing a skin 14 on the outer surface of the battery frame 1, the skin 14 can serve as an outer cover, which can improve the aesthetics of the battery frame 1 and protect the various components inside the battery frame 1.

[0048] It is understandable that the skin 14 has a mounting hole 140 at the position corresponding to the forklift hole 121. The shape and size of the mounting hole 140 are the same as those of the forklift hole 121, so that the forks of the power swapping equipment can pass through the mounting hole 140 on the skin 14 and extend into the forklift hole 121.

[0049] like Figure 8As shown, in some embodiments, a heat dissipation grid 145 may be provided on the skin 14 at the location of the thermal management unit 24. The heat dissipation grid 145 consists of a plurality of evenly arranged heat dissipation holes, which can enhance heat dissipation efficiency.

[0050] Optionally, it also includes a top cover 15, which is detachably connected to the second side 112, or the top cover 15 is detachably connected to the top surface of the first bracket 12 along the first direction Z.

[0051] Specifically, such as Figure 8 and Figure 9 As shown, the top cover 15 can be connected to the second side 112 of the main frame 11 by means of snap-fit, magnetic connection, or other detachable connection methods, or as... Figure 4 and Figure 5 As shown, the top cover 15 can be detachably connected to the top surface of the first bracket 12 along the first direction Z by means of snap-fit, magnetic attraction, or other detachable connection. In this way, by setting the top cover 15, the internal components of the battery frame 1 can be protected. The top cover 15 is detachably connected to the main frame 11 or the first bracket 12, which facilitates the disassembly and maintenance of the battery box 2.

[0052] In some embodiments, the top cover 15 can be made of steel Q345, which makes the top cover 15 stronger and thus allows the top cover 15 to resist the impact of falling rocks in the mining area, and better protect the internal components of the battery frame 1.

[0053] Optionally, it also includes a second bracket 16, which is fixedly connected to the first side 111; wherein, the second bracket 16 is provided with a plurality of locking blocks 162, which are used to cooperate with the locking structure 321 of the vehicle base 32 of the vehicle 3.

[0054] Specifically, such as Figure 12 As shown, the second bracket 16 is a rectangular frame formed by connecting several rectangular tubes. The second bracket 16 is welded to the first side 111 of the main frame 11. The second bracket 16 is used to install the charging plug and the first connector. The material of the second bracket 16 can also be 700 high-strength steel.

[0055] like Figure 12 As shown, the second bracket 16 is provided with multiple locking blocks 162 on both sides along the third direction Y. The locking blocks 162 correspond to the locking structure 321 of the vehicle base 32. In this way, when the battery box 2 is installed, the locking blocks 162 cooperate with the locking structure 321 to lock the battery box 2, restricting the degree of freedom of the battery box 2 in the first direction Z, the second direction X and the third direction Y, and firmly fixing the battery box 2 on the vehicle base 32, thereby improving the reliability of the connection between the battery box 2 and the vehicle base 32.

[0056] In some embodiments, the second bracket 16 is further provided with a plurality of positioning blocks on both sides along the third direction Y. The positioning blocks are provided with positioning holes 161. The positioning holes 161 correspond to the positions of the positioning pins 322 of the vehicle base 32. When the battery box 2 is installed on the vehicle base 32, the positioning pins 322 are inserted into the positioning holes 161 to achieve precise positioning of the battery box 2.

[0057] Optionally, such as Figure 2 As shown, the main frame 11 includes two side supports 113 and multiple intermediate supports 114; the two side supports 113 are spaced apart along the third direction Y, and the two ends of the two side supports 113 along the first direction Z are respectively connected to the first support 12 and the second support 16, and the multiple intermediate supports 114 are arranged between the two side supports 113 along the first direction Z; wherein, the third direction Y is perpendicular to the first direction Z and the second direction X.

[0058] Specifically, the third party to Y is as follows: Figure 1 The Y-axis direction shown is the width direction of the battery frame 1. The third direction Y, the first direction Z, and the second direction X are perpendicular to each other.

[0059] like Figure 13 As shown, the side support 113 is a rectangular frame formed by connecting several rectangular tubes. The two side supports 113 have the same structure. The rectangular tubes on the side support 113 can form V-shaped and / or X-shaped supports to improve the strength of the side support 113.

[0060] like Figure 14 As shown, the intermediate support 114 is a rectangular frame formed by connecting several rectangular tubes, and the multiple intermediate supports 114 have the same structure. Each intermediate support 114 is provided with multiple battery pack 23 mounting positions, and the battery packs 23 are installed in the battery pack 23 mounting positions. The intermediate support 114 and the side support 113 can both be made of 700 high-strength steel.

[0061] The two side supports 113 are welded to the first support 12 at their top ends along the first direction Z, and to the second support 16 at their bottom ends along the first direction Z. The two side supports 113 are spaced apart along the third direction Y, and a plurality of intermediate supports 114 are arranged between the two side supports 113 along the first direction Z, and the plurality of intermediate supports 114 are welded to the side supports 113.

[0062] In this embodiment, the main frame 11 is divided into two side supports 113 and multiple intermediate supports 114. The intermediate supports 114 and the side supports 113 can be welded separately and then assembled, which reduces the amount of manual welding during the overall welding process, improves manufacturing efficiency, and ensures welding accuracy.

[0063] In some embodiments, the overall outline dimensions of the battery frame 1 can be 3600*1400*1700mm (length*width*height), the extended version can be 4200*1400*1700mm, and the corresponding height versions can be 3600*1400*2000mm and 4200*1400*2000mm respectively, with a dimensional error of ±50mm. The extension and height are mainly for matching the dimensions of electric vehicles with different load capacities.

[0064] In summary, the battery frame 1 provided in this application embodiment has at least the following advantages: In this embodiment, the battery frame 1 includes a main frame 11 and a first bracket 12. A forklift hole 121 is provided on one side of the first bracket 12 along the second direction X. The forklift hole 121 penetrates the first bracket 12 along the second direction X. Thus, when the battery box 2 needs to be replaced, the battery swapping device can be inserted into the forklift hole 121 from the side of the main frame 11 along the second direction X. That is, the battery swapping device can pick up the battery box 2 from the side of the battery frame 1 along the second direction X, which can improve the stability of the battery box 2 during replacement and reduce the occurrence of problems such as the battery box 2 being bumped.

[0065] This application embodiment also provides a battery box 2, which includes a battery frame 1 as described in any of the above embodiments, a charging socket 21, a first connector 22, multiple battery packs 23, a thermal management unit 24, and a control box 25 installed on the battery frame 1. The thermal management unit 24 is connected to the battery packs 23, the control box 25 is electrically connected to the battery packs 23, the first connector 22 is electrically connected to the control box 25, and the charging socket 21 is electrically connected to the control box 25.

[0066] Specifically, such as Figures 15-17 As shown, the charging socket 21 is fixedly connected to the second bracket 16 of the battery frame 1, and the charging socket 21 can be located on the side of the second bracket 16 along the second direction X. The first connector 22 is fixedly connected to the second bracket 16 of the battery frame 1, and the first connector 22 can be located in the middle of the second bracket 16, corresponding to the position of the second connector 33 on the vehicle base 32. The battery pack 23 is fixedly connected to the intermediate bracket 114 of the battery frame 1, and multiple battery packs 23 are arranged on multiple intermediate brackets 114. The number of battery packs 23 is not specifically limited in this embodiment. The thermal management unit 24 is fixedly connected to the first bracket 12 of the battery frame 1, and there can be at least two thermal management units 24, which are spaced apart on the first bracket 12 along the second direction X. The control box 25 is fixedly connected to the first bracket 12 of the battery frame 1, and the control box 25 can be located between two thermal management units 24.

[0067] Battery pack 23 (e.g.) Figure 20As shown, the smallest unit of the battery is a single battery pack 23. For example, the capacity of a single battery pack 23 can be 35-50 kWh, and the outline dimensions can be 1210 mm * 640 mm * 250 mm. The voltage and capacity required by the battery box 2 can be achieved by connecting multiple battery packs 23 in series and / or in parallel.

[0068] Thermal management unit 24 (e.g.) Figure 21 As shown, the thermal management unit 24 is connected to multiple battery packs 23 via cooling pipes. It contains a low-temperature resistant coolant to cool the battery packs 23, preventing overheating or even spontaneous combustion during prolonged use. The thermal management unit 24 also includes a heating module that activates when the vehicle is cold to heat the battery packs 23, thus preventing a significant reduction in discharge efficiency due to low temperatures affecting the battery packs 2. For example, the thermal management unit 24 has a cooling capacity of 10 kW and a heating capacity of 24 kW.

[0069] Control box 25 (e.g.) Figure 22 (as shown) is electrically connected to the wiring harness of multiple battery packs 23 in series and / or parallel, and to the first connector 22 (as shown) Figure 19 As shown, via electrical connections using wiring harnesses, the control box 25 can integrate the series and / or parallel wiring harnesses of multiple battery packs 23 and transmit them uniformly to the first connector 22. The first connector 22 is used to electrically connect to the second connector 33 on the vehicle's mounting base 32. Thus, the first connector 22 can transmit the current and voltage from the control box 25 to the second connector 33, and then to the entire vehicle 3 via the second connector 33. For example, the first connector 22 may have 36 low-voltage pins, 4 high-voltage positive and negative pins, and 2 ground pins.

[0070] Charging socket 21 (e.g.) Figure 18 As shown, the battery pack 23 is electrically connected to the control box 25 via a wiring harness. An external charging device, such as a charging gun, can be plugged into the charging socket 21 to charge the battery pack 23. For example, the charging current can be 300A.

[0071] It should be noted that in this embodiment, the structure of the battery frame 1 is the same as that of the battery frame 1 described in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.

[0072] This application embodiment also provides a vehicle 3, which includes the battery box 2, vehicle base 32 and vehicle body 31 described in the above embodiment. The vehicle base 32 is connected to the vehicle body 31, and the battery box 2 is connected to the vehicle base 32. The vehicle base 32 is provided with a plurality of locking structures 321, and the locking structures 321 are connected to the locking block 162 of the battery frame 1.

[0073] Specifically, such as Figure 23 and Figure 24 As shown, vehicle 3 can be an electric mining truck or other electric vehicle 3. The vehicle base 32 is connected to the frame above the cab of the vehicle body 31, and the battery box 2 is connected to the top of the vehicle base 32.

[0074] like Figure 25 As shown, the vehicle base 32 can be a rectangular frame made of multiple rectangular steel pieces. A second connector 33 is connected to the top of the vehicle base 32 along the first direction Z. The second connector 33 corresponds to the position of the first connector 22. When the battery box 2 is installed on the vehicle base 32, the second connector 33 and the first connector 22 are plugged in. Then, the first connector 22 can transmit the current and voltage of the control box 25 to the second connector 33, and then transmit them to the entire vehicle 3 through the second connector 33.

[0075] Multiple locking structures 321 are provided at intervals on both sides of the vehicle base 32 along the third direction Y. The locking structures 321 correspond to the locking blocks 162 on the battery frame 1. When the battery box 2 is installed on the vehicle base 32, the locking structures 321 are connected to the locking blocks 162 to lock the battery box 2, restricting the freedom of the battery box 2 in the first direction Z, the second direction X and the third direction Y, and firmly fixing the battery box 2 on the vehicle base 32, thereby improving the reliability of the connection between the battery box 2 and the vehicle base 32.

[0076] Optionally, such as Figure 25 and Figure 26 As shown, the vehicle base 32 has multiple positioning pins 322 on both sides along the third direction Y. The positioning pins 322 correspond to the positioning holes 161 on the battery frame 1. When the battery box 2 is installed on the vehicle base 32, the positioning pins 322 are inserted into the positioning holes 161 to achieve precise positioning of the battery box 2. Furthermore, the vehicle base 32 has coarse positioning blocks 323 on both sides along the second direction X. The top of the coarse positioning blocks 323 along the first direction Z has a guide slope. When the battery box 2 is installed on the vehicle base 32, the guide slope of the coarse positioning blocks 323 enters the interior of the battery frame 1 to achieve coarse positioning of the battery frame 1. Through the coarse positioning blocks 323 and multiple positioning pins 322, quick guidance and positioning can be achieved, improving the safety of the battery box 2 during installation, and enabling the first connector 22 and the second connector 33 to be precisely inserted.

[0077] In some alternative embodiments, such as Figure 27 and Figure 28As shown, the locking structure 321 may include a locking seat 3211, a driving member 3212, a first connecting rod 3213, a second connecting rod 3214, and a locking tongue 3215. The locking seat 3211 is connected to the vehicle base 32 and has a receiving cavity. The power output end 32121 of the driving member 3212 extends into the receiving cavity, and the power output end 32121 of the driving member 3212 is connected to one end of the first connecting rod 3213. A portion of the locking tongue 3215 is located inside the receiving cavity, and the other portion extends out of the receiving cavity. The second connecting rod 3214 is fixedly connected to the cavity wall of the receiving cavity. The portion located in the receiving cavity is connected to the other end of the first connecting rod 3213, and the portion of the locking tongue 3215 located in the receiving cavity is rotatably connected to the second connecting rod 3214. The power output end 32121 of the driving member 3212 extends and retracts, driving the first connecting rod 3213 to move. The first connecting rod 3213 drives the locking tongue 3215 to rotate relative to the second connecting rod 3214, causing the locking tongue 3215 to abut against or separate from the locking block 162, thereby locking or unlocking the battery box 2. This increases the locking force of the locking structure 321, thereby improving the reliability of the connection between the battery box 2 and the vehicle base 32. Furthermore, the driving member 3212 can be a linear drive cylinder, hydraulic cylinder, etc.

[0078] In some optional embodiments, the vehicle base 32 is uniformly provided with a plurality of pads at the top along the first direction Z. The pads can be made of soft materials such as rubber or silicone. By providing the pads, the pads can absorb the tolerances and provide a buffer force in bad road conditions, so that the battery frame 1 will not directly hit the vehicle base 32, thereby reducing the impact of bad road conditions on the battery frame 1 and the vehicle base 32, protecting the battery frame 1 and the vehicle base 32, and extending the service life of the battery frame 1 and the vehicle base 32.

[0079] It should be noted that in this embodiment, the structure of the battery box 2 is the same as that of the battery box 2 described in the above embodiment, and its beneficial effects are also similar, so it will not be described again here.
