Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a high-voltage box and a battery box. Background Technology

[0002] A battery box typically includes a battery pack, a high-voltage box, a top frame, and a bottom frame. The top and bottom frames are spaced vertically apart, with the battery pack positioned between them, and the high-voltage box mounted on the bottom frame. In previous designs, such as the battery box described in patent application number 202410201848.4, the bottom frame was relatively tall, with a large internal space. An installation opening was created on the side wall of the bottom frame, allowing the high-voltage box to be inserted into the bottom frame. The connecting lugs on the periphery of the high-voltage box then overlapped with corresponding structures within the bottom frame, and bolts were used to secure it. However, in the new design, the bottom frame height has been reduced, making it impossible to create an installation opening on the side wall. The high-voltage box can only be installed on one side of the bottom of the battery box. However, the connecting lugs of the current high-voltage box are horizontal, requiring vertical bolting for fixation. Furthermore, the connecting lugs have a short extension, making quick and efficient assembly with the bottom frame of the battery box difficult. Utility Model Content

[0052] Example 1

[0053] See Figures 1 to 11As shown, this application embodiment provides a high-voltage box 4 for a battery box. The high-voltage box 4 includes a high-voltage box body 41 and an adapter frame. A connecting ear 411 is provided on the edge of the high-voltage box body 41, and an ear hole 4111 is provided on the connecting ear 4111. The adapter frame is located around the high-voltage box body 41 and is detachably connected to the connecting ear 411. An adapter hole 4221 is provided on the adapter frame, and the extending direction of the adapter hole 4221 is perpendicular to the extending direction of the ear hole 4111, for detachable connection with the frame 1.

[0054] The battery box 100 typically includes a battery pack 2, a high-voltage box 4, a top frame 12, and a bottom frame 11. The top frame 12 and the bottom frame 11 are spaced vertically apart. The battery pack 2 is positioned between the top frame 12 and the bottom frame 11, and the high-voltage box 4 is mounted on the bottom frame 11. In previous designs, the bottom frame 11 was relatively tall, resulting in a large internal space. An installation opening was created on the side wall of the bottom frame 11, allowing the high-voltage box 4 to be inserted into the bottom frame 11. The connecting lugs 411 around the high-voltage box 4 then overlapped with corresponding structures within the bottom frame 11, and the high-voltage box 4 was secured with bolts. The bolts extended along the height of the battery box 100. However, in the new design, the height of the bottom frame 11 has been reduced, making it impossible to create an installation opening on the side wall of the bottom frame 11. Therefore, the high-voltage box 4 is mounted from the bottom side of the battery box 100. This means that when assembling the high-voltage box 4, the battery box 100 needs to be lifted, and then the high-voltage box 4 is assembled from bottom to top. However, in the prior art, the connecting ears 411 of the high-voltage box 4 are horizontally positioned. The ear holes 4111 on the horizontal structure allow bolts to be fixed only vertically (in the height direction of the battery box 100), and the extension dimension of the connecting ears 411 is short, making it difficult or impossible to quickly and effectively assemble them with the bottom frame 11 of the battery box 100. To solve this technical problem, the high-voltage box body 41 of the high-voltage box 4 provided in this application embodiment is connected to an adapter frame via the connecting ears 411. The extension direction of the adapter hole 4221 on the adapter frame is perpendicular to the extension direction of the ear hole 4111, changing the installation direction. That is, the bolts can extend horizontally to fix the high-voltage box 4, thereby facilitating the transfer and assembly of the high-voltage box 4 onto the battery box 100, simplifying the assembly structure, and significantly improving assembly efficiency. It should be noted that in this application, the extension direction of the hole can be understood as the thickness direction of the corresponding carrier, or the extension direction of the internal channel of the hole.

[0055] In some possible implementations, the adapter frame is provided with connection holes, and fasteners pass through the connection holes and the ear holes 4111 on the connection ears 411 to connect and fix the high voltage box body 41 and the adapter frame.

[0056] Specifically, the connecting hole has an internal thread, and the fastener has a stud and a cap. The stud passes through the ear hole 4111 of the connecting ear 411 and is threaded into the connecting hole. The cap is confined within the connecting ear 411. The fastener can be a bolt. The bolt and the adapter bracket increase the edge size of the high-voltage box 4, allowing the adapter bracket to extend to the corresponding structure on the bottom frame 11 of the battery box 100, facilitating the connection and fixation of the adapter bracket and the corresponding structure on the bottom frame 11.

[0057] In some possible implementations, such as Figures 3 to 6 As shown, the adapter frame includes two adapter beams 42, which are respectively located on both sides of the high-voltage box body 41, and the adapter beams 42 are connected to corresponding connecting ears 411. The adapter beams 42 are provided with adapter holes 4221. The two adapter beams 42 are fixed to the bottom frame 11 by fasteners to stably and effectively assemble the high-voltage box body 41.

[0058] In some possible implementations, the transition beam 42 has a hollow cavity and an operating hole 4231, both of which are connected to the hollow cavity. The transition hole 4221 is exposed to the operating hole 4231, and the fastener 1113 can be connected to the frame 1 by passing through the operating hole 4231 and the transition hole 4221 in sequence.

[0059] The operation hole 4231 serves to avoid the fasteners, allowing the fasteners to pass through the operation hole 4231 and smoothly connect the adapter beam 42 to the bottom frame 11 of the battery box 100.

[0060] In some possible implementations, the transition beam 42 includes a first strip 421, a second strip 422, and a third strip 423. The first strip 421 and the second strip 422 are vertically connected, and the third strip 423 is connected to the first strip 421 and the second strip 422 respectively. A sleeve 424 is provided on the first strip and the third strip. The sleeve 424 has a connecting hole, and a fastener 1113 can pass through the ear hole 4111 of the connecting ear 411 and be threaded into the connecting hole of the sleeve 424 to connect and fix the high-voltage box body 41 and the transition beam 42. The second strip has a transition hole 4221, and the third strip has an operating hole 4231.

[0061] like Figure 4 As shown, the cross-section of the transition beam 42 is a right-angled triangle. Two reinforcing beams 117 can be spaced apart on the inner side of the bottom frame 11. The high-voltage box 4 is located between the two reinforcing beams 117, and both sides of the high-voltage box body 41 are connected to the corresponding reinforcing beams 117 via transition frames. That is, fasteners are threaded onto the reinforcing beams 117 through the transition holes 4221.

[0062] In some possible implementation schemes, combined Figures 3 to 5As shown, the high-voltage box 4 includes a support member 44, the high-voltage box body 41 has a bottom surface, an electrical connector 43 is provided on the bottom surface, the support member 44 is connected to the high-voltage box body 41, and the support member 44 protrudes from the electrical connector 43 in the direction perpendicular to the bottom surface.

[0063] When the high-voltage box 4 is supported on the support surface, the support member 44 directly contacts the support surface, while there is a gap between the electrical connector 43 and the support surface to avoid the electrical connector 43 and the support surface directly abutting each other, which would cause damage and deformation to the electrical connector 43 and result in economic losses.

[0064] In some possible implementations, the support member 44 includes a support plate extending along the periphery of the electrical connector 43, which can be directly connected to the bottom surface or periphery of the high-voltage box body 41. The support plate is provided with a weight-reducing groove 441. The weight-reducing groove 441 serves to reduce weight and prevent the high-voltage box body 41 from becoming excessively heavy.

[0065] In some possible implementations, such as Figure 4 As shown, at least a portion of the support plate includes a main plate 442 and a bent plate 443. The main plate 442 is connected to the high-voltage box body 41, and the bent plate 443 is fitted to the main plate 442, formed by bending the main plate 442. The bent plate 443 increases the thickness of the lower edge of the support plate, improving its structural strength. The bent plate 443 also makes the lower edge of the support plate smooth, preventing sharp edges from easily cutting or damaging the external structure.

[0066] In this embodiment, the battery box 100 includes: a frame 1 and the aforementioned high-voltage box 4. A battery pack 2 is disposed on the frame 1. The adapter frame of the high-voltage box 4 is detachably connected to the frame 1 through an adapter hole 4221. The high-voltage box body 41 of the high-voltage box 4 is electrically connected to the battery pack 2.

[0067] The frame 1 may include a top frame 12 and a bottom frame 11, which are spaced apart vertically. The battery pack 2 is disposed between the top frame 12 and the bottom frame 11, and the high-voltage box 4 is mounted on the bottom frame 11. The specific assembly structure of the high-voltage box 4 and the frame 1 has been described in detail above, and will not be repeated here.

[0068] Example 2

[0069] See Figures 1 to 11 As shown, this application embodiment provides a precision positioning device 111 for a battery box 100, such as... Figure 9As shown, it includes: an aluminum block 1111 and a wear-resistant component 1112. The aluminum block 1111 has a slot 11111 and is used for connection and fixation. The wear-resistant component 1112 has a connecting plate 11121 and a positioning sleeve 11122. The connecting plate 11121 is attached to the surface of the aluminum block 1111 and is detachably connected to the aluminum block 1111. The positioning sleeve 11122 is connected to the connecting plate 11121 and is inserted into the slot 11111. The connecting plate 11121 has an insertion port communicating with the positioning sleeve 11122.

[0070] When the battery box 100 equipped with the precision positioning device 111 is placed on the battery box base 200, the guide post on the battery box base 200 can be inserted into the positioning sleeve 11122 through the insertion port and fit against the inner wall of the positioning sleeve 11122. The guide post and the slot 11111 of the aluminum block 1111 do not make direct contact, thereby avoiding wear on the aluminum block 1111.

[0071] Wear-resistant part 1112 can be made of steel or nylon sleeves, etc. It has extremely high wear resistance, can withstand frequent friction, is not easily worn, and thus extends its service life. Wear-resistant part 1112 performs excellently overall and can maintain stable performance in various harsh environments.

[0072] The precision positioning device 111 of this application comprises two parts: an aluminum block 1111 for welding to or connecting to the aluminum frame 1 via fasteners, and a wear-resistant part made of wear-resistant material that can rub against the guide posts on the battery box base 200 for a long time without being severely worn, thereby extending the service life of the precision positioning device 111. When replacing the precision positioning device 111, only the wear-resistant part 1112 needs to be disassembled and replaced, making the operation relatively convenient.

[0073] In some possible implementations, the connecting plate 11121 is provided with a plurality of connecting holes 11121a, which are spaced apart sequentially along the circumference of the insertion port. A plurality of fasteners 1113 are connected to the aluminum block 1111 by passing one end through the corresponding connecting hole 11121a, while the other end of the fasteners 1113 is confined to the connecting plate 11121. When it is necessary to replace the wear-resistant part 1112, the wear-resistant part 1112 can be easily replaced by removing each fastener 1113.

[0074] In some possible implementations, the aluminum block 1111 is provided with multiple threaded grooves, which are arranged sequentially at intervals along the circumference of the slot 11111. The fastener 1113 has a screw and a cap. The screw passes through the connecting hole 11121a and is threaded into the threaded groove, and the cap is confined to the connecting plate 11121. The fastener 1113 is a bolt, which is relatively convenient for disassembly and assembly.

[0075] In some possible implementations, the slot 11111 penetrates the aluminum block 1111, so that the top of the slot 11111 is open to the atmosphere, thus preventing the top of the slot 11111 from being blocked, which would cause compressed air during the insertion of the guide post into the slot 11111, thus affecting the fit between the guide post and the precision positioning device 111.

[0076] In some possible implementations, the extension length of the positioning sleeve 11122 is less than the extension length of the slot 11111, which is sufficient to meet the insertion fit with the guide post, saving materials and facilitating the disassembly and assembly of the wear-resistant part 1112 and the aluminum block 1111.

[0077] In some possible implementations, the aluminum block 1111 is approximately a cube with multiple flat surfaces. A slot 11111 is provided on one of these flat surfaces, and a connecting plate 11121 covers the flat surface with the slot. The connecting plate 11121 is designed to match the area of ​​the flat surface with the slot as closely as possible, thereby fully covering the side of the aluminum block 1111 facing the battery box base 200. This increases the contact area between the wear-resistant part 1112 and the battery box base 200, which is beneficial for the stable fit between the battery box 100 and the battery box base 200.

[0078] This application embodiment also provides a battery box 100, including: a frame 1 and the above-mentioned precision positioning device 111, the battery box 100 is disposed on the frame 1, and the precision positioning device 111 is disposed on the frame 1.

[0079] As the battery box 100 gradually settles onto the battery box base 200 from top to bottom, the guide post on the battery box base 200 can be inserted into the positioning sleeve 11122 through the insertion port and fit against the inner wall of the positioning sleeve 11122. The guide post on the battery box base 200 and the slot 11111 of the aluminum block 1111 do not directly contact each other, thereby avoiding wear on the aluminum block 1111.

[0080] In some possible implementations, the frame 1 is an aluminum frame 1, and the aluminum block 1111 of the precision positioning device 111 is welded to the aluminum frame 1. The aluminum frame 1 and the aluminum block 1111 are made of the same material, which can be easily welded and fixed.

[0081] The aluminum block 1111 has a circumferentially extending side surface around the slot 11111 and a top surface and a bottom surface respectively located at both ends of the circumferentially extending side surface. The bottom surface and the top surface are provided with slots that communicate with the slot 11111. The connecting plate 11121 covers the bottom surface, with the bottom surface facing the battery box base 200. The circumferentially extending side surface of the aluminum block 1111 is welded to the aluminum frame 1.

[0082] In some possible implementations, the peripheral side has a plurality of straight sides arranged in sequence, with two adjacent sides perpendicular to each other, the frame 1 has a right-angle region, the aluminum block 1111 is located in the right-angle region, and two adjacent sides of the aluminum block 1111 are respectively attached and welded to the two boundary surfaces of the right-angle region of the frame 1.

[0083] In some possible implementations, such as Figure 5 As shown, an electrical connector 43 is provided at the bottom of the frame 1, and the battery box 100 has multiple precision positioning devices 111, each located around the electrical connector 43. An electrical connector 43 is also provided on the battery box base 200, and multiple guide posts are also provided on the battery box base 200 around its electrical connector. By providing precision positioning devices 111 around the electrical connector 43, it is beneficial to ensure that the electrical connector 43 on the battery box 100 can be accurately aligned and reliably connected with the electrical connector on the battery box base 200 when the battery box 100 is seated.

[0084] Example 3

[0085] See Figures 1 to 12 As shown, this application embodiment provides a battery box 100 with a locking engagement part, including: a frame 1, a battery pack 2, and a locking tongue engagement platform 112. A battery mounting space is formed inside the frame 1, and a locking engagement groove 1153 is provided on the frame 1. The battery pack 2 is disposed within the battery mounting space. The locking tongue engagement platform 112 is disposed within the locking engagement groove 1153. The locking tongue engagement platform 112 has a first body 1121 and a second body 1122. The first body 1121 is connected to the inner wall of the locking engagement groove 1153, and the second body 1122 covers the first body 1121 and is detachably connected to the first body 1121. When the locking tongue 210 of the locking mechanism is inserted into the locking engagement groove 1153, the locking tongue 210 abuts against the second body 1122 of the locking tongue engagement platform 112.

[0086] In this embodiment, a latch mating platform 112 is provided in the locking groove 1153 of the battery box 100, which can directly contact and engage with the latch 210 of the locking mechanism on the battery box base 200 to prevent damage to the main structure of the frame 1. The latch mating platform 112 is made of wear-resistant material, such as steel, for a long service life. The latch mating platform 112 includes a first body 1121 and a second body 1122. The second body 1122 is detachable for easy replacement, eliminating the need to replace the first body 1121 and saving materials.

[0087] In some possible implementations, the first body 1121 is provided with threaded grooves, and the two ends of the second body 1122 are respectively provided with connecting holes. Two first fasteners 1123 are threaded at one end through the corresponding connecting holes and connected to the threaded grooves on the first body 1121, while the other end of the first fasteners 1123 is confined to the second body 1122. The first fasteners 1123 can be bolts, and the second body 1122 can be easily disassembled and assembled by tightening the bolts. The first fasteners 1123 are only connected to the first body 1121 and are not used to connect the frame 1, resulting in a simple structure and easy disassembly and assembly.

[0088] like Figure 12 As shown, in some possible implementations, the side of the second body 1122 facing away from the first body 1121 is provided with an inclined surface 11221, and the end of the inclined surface 11221 near the inner side of the frame 1 (bottom frame) is lower than the end of the inclined surface 11221 near the outer side of the frame 1.

[0089] like Figure 12 As shown, at least part of the upper surface of the second body 1122 is an inclined platform, and the locking tongue 210 of the locking mechanism is a rotary swing type locking tongue 210. When the locking tongue 210 swings, it is inserted into the locking mating groove 1153 from the inner side of the frame 1. The locking tongue 210 directly abuts against the inclined platform. The inclined platform and the rotary swing type locking tongue 210 are more compatible, and the locking force of the locking tongue 210 is greater, which can effectively and reliably lock the battery box 100.

[0090] In some possible implementations, the first body 1121 is connected to the frame 1 at both ends along its length by second fasteners 1124, and the second body 1122 is located between the two second fasteners 1124. The second body 1122 is directly fixed to the frame 1 by fasteners, and the first body 1121 is not easily disassembled, so that the first body 1121 can maintain a stable and reliable assembly relationship with the frame 1.

[0091] In some possible implementations, such as Figure 11 As shown, the frame 1 includes an outer frame plate with a locking groove 1153. A cylindrical member 1125 is provided inside the outer frame plate. The cylindrical member 1125 has a threaded groove. One end of the second fastener 1124 passes through the first body 1121 and is threadedly connected to the threaded groove of the cylindrical member 1125. The other end of the second fastener 1124 is limited to the first body 1121.

[0092] The outer frame plate can be made of pure aluminum profile with a certain thickness, sufficient to accommodate the locking tongue mating platform 112 after the locking groove 1153 is opened. An accommodating space is provided inside the outer frame plate, and the cylindrical component 1125 is embedded in and fixed within this space. The cylindrical component 1125 is an internally threaded cylinder, and the second fastener 1124 is a bolt. The bolt's stud can be threaded into the internally threaded cylinder, while the bolt's head is confined to the first platform 1121. The second platform 1122 is located between the two second fasteners 1124 and will not interfere with the second fasteners 1124.

[0093] In some possible implementations, the locking groove 1153 extends through the outer frame plate along the thickness direction of the outer frame plate.

[0094] Specifically, the outer frame plate includes a profile plate and a sealing plate. A cylindrical component 1125 is provided inside the profile plate, and the sealing plate covers the profile plate. The locking groove 1153 includes a through opening provided on the profile plate and an observation opening provided on the sealing plate.

[0095] The observation port allows for easy observation of whether the latch 210 and the latch mating platform 112 are properly engaged. In the event of a malfunction where the latch 210 cannot retract, the observation port allows for easy application of external force to the latch 210 using an external structure to release the latch 210's locking mechanism.

[0096] In some possible implementations, such as Figure 10 As shown, a vertical rib 1161 is provided in the inner cavity of the plate segment below the locking groove 1153 of the profile plate, and the vertical rib 1161 extends along the height direction of the battery box 100. A horizontal rib 1162 is provided in the inner cavity of the plate segment below the locking groove 1153 of the profile plate, and the horizontal rib 1162 is vertically connected to the vertical rib 1161. The provision of the vertical rib 1161 can increase the vertical support structure strength of the profile plate and can withstand the downward pressure applied by the locking tongue 210. The provision of the horizontal rib 1162 can connect the vertical rib 1161, increase the structural strength of the vertical rib 1161, and prevent the vertical rib 1161 from being skewed under force, which would weaken the vertical support effect.

[0097] In some possible implementations, such as Figure 11 As shown, a pad 113 is provided at the lower edge of the frame 1 corresponding to the locking groove 1153. The force between the lower edge of the frame 1 corresponding to the locking groove 1153 and the support surface is the greatest. By adding the pad 113 at this location, the pad 113 will directly contact the support surface, protecting the pure aluminum frame 1 structure and preventing the frame 1 structure from deforming under external force.

[0098] Example 4

[0099] See Figures 1 to 12As shown in the embodiment of this application, the frame 1 of the battery box 100 is described in detail, which includes: a bottom frame 11, a middle frame 13 and a top frame 12. The bottom frame 11 includes a plurality of outer frame plates, which are connected to each other and form a bottom cavity. The top frame 12 and the bottom frame 11 have a gap. The middle frame 13 is located between the bottom frame 11 and the top frame 12 and is connected to the top frame 12 and the bottom frame 11 respectively. A battery mounting space is formed between the top frame 12 and the bottom frame 11. The outer frame plates are hollow plates. The end of the outer frame plate near the battery mounting space has a solid part 1142. The solid part 1142 has a threaded groove for connecting the battery pack 2 and / or the middle frame 13.

[0100] In this application, the outer frame plate is a hollow structure, which is beneficial for weight reduction. The top of the outer frame plate has a solid structure, and the solid part has a threaded groove to facilitate connection and fixation with the battery pack 2 and / or the middle frame 13. While reducing weight, it ensures that the connection structure between the battery pack 2 and / or the middle frame 13 and the bottom frame 11 has high strength and good stability.

[0101] In some possible implementations, such as Figure 10 and Figure 11 As shown, the outer frame plate has a first plate segment 114 near the battery mounting space. The first plate segment 114 has a hollow groove 1141 and a solid part 1142. The solid part 1142 and the hollow groove 1141 are arranged sequentially along the thickness direction of the first plate segment 114.

[0102] The first plate segment 114 is the top segment of the outer frame plate. The first plate segment 114 is not entirely a solid structure, but one side along the thickness direction is a solid structure to facilitate the opening of threaded grooves. The other side of the first plate segment 114 is a hollow groove 1141, which has the effect of weight reduction and will not affect the connection between the solid part 1142 and the battery pack 2 or the middle frame 13.

[0103] In some possible implementations, the outer frame panel has a second segment 115 connected to the side of the first segment 114 opposite to the battery mounting space. The second segment 115 includes two outer side panels 1151 and multiple stiffeners 1152. The two outer side panels 1151 are spaced apart and arranged parallel to each other, and each stiffener 1152 is disposed between the two outer side panels 1151. The two outer side panels 1151 are connected to the two stiffeners 1152 on both sides, forming multiple cavities between the two outer side panels 1151 and each stiffener 1152. The second segment 115 and the first segment 114 are a single piece, and the entire outer frame panel can be made of aluminum alloy profile. The second segment 115 has a large number of hollow cavities inside, resulting in a significant weight reduction effect.

[0104] In some possible implementations, each stiffener 1152 is inclined and the stiffener 1152 divides the space between the two outer side plates 1151 to form a plurality of triangular prism-shaped cavities.

[0105] In this implementation scheme, the second plate segment 115 is located at the midpoint of the outer frame plate of the bottom frame 11 along its height, making it susceptible to impacts from external structures. The cross-section of the second plate segment 115 has a large number of triangular structures, which gives it extremely high stability. It can withstand various forces and external forces while remaining stable, significantly improving the overall stability of the structure and reducing the risk of deformation and damage.

[0106] In some possible implementations, a locking groove 1153 is provided on the second plate segment 115, and the locking groove 1153 extends along the thickness direction of the second plate segment 115. When the battery box 100 with the frame 1 is unloaded onto the battery box base 200, the locking tongue 210 of the locking mechanism on the battery box base 200 can be inserted into the locking groove 1153 to fix the frame 1.

[0107] In some possible implementations, the outer frame plate has a third plate segment 116, which is located on the side of the second plate segment 115 away from the first plate segment 114, and a vertical rib 1161 is provided in the cavity of the third plate segment 116. A horizontal rib 1162 is provided in the cavity of the third plate segment 116, and the horizontal rib 1162 is vertically connected to the vertical rib 1161.

[0108] Vertical ribs 1161 extend along the height of frame 1. The vertical ribs 1161 increase the vertical support structure strength of the profile plate and can withstand the downward pressure applied by the locking tongue 210. Horizontal ribs 1162 connect to the vertical ribs 1161, increasing the structural strength of the vertical ribs 1161 and preventing the vertical ribs 1161 from becoming skewed under stress, which would weaken the vertical support effect.

[0109] In some possible implementations, the frame 1 of the battery box 100 includes a latch mating platform 112, a locking groove 1153 is provided on the lower edge of the second plate segment 115, the latch mating platform 112 is located in the locking groove 1153, and the latch mating platform 112 is connected to the third plate segment 116 by fasteners.

[0110] The battery box 100 has a locking groove 1153 with a locking tongue mating platform 112 that can directly contact and engage with the locking tongue 210 of the locking mechanism to prevent damage to the main structure of the frame 1. The locking tongue mating platform 112 is made of wear-resistant material; if steel can be used, it will have a long service life.

[0111] In some possible implementations, such as Figure 11As shown, the frame 1 of the battery box 100 includes a cylindrical member 1125, which is disposed within the third plate segment 116. The cylindrical member 1125 has a threaded groove. One end of a fastener passes through the locking tongue mating platform 112 and is threadedly connected to the threaded groove of the cylindrical member 1125, while the other end of the fastener is confined to the locking tongue mating platform 112. The fastener can be a bolt, with the stud of the bolt passing through the locking tongue mating platform 112 and threadedly connected to the cylindrical member 1125, and the head of the bolt confined to the locking tongue mating platform 112.

[0112] This embodiment also provides a battery box 100, including the aforementioned frame 1 and battery pack 2. The battery pack 2 is disposed within the battery mounting space, with one end of a fastener passing through the battery pack 2 and threadedly connected to a threaded groove on the outer frame plate, and the other end of the fastener confined within the battery pack 2. The middle frame 13 can also adopt the same mounting method; for example, one end of a fastener passes through the middle frame and is threadedly connected to a threaded groove on the outer frame plate, and the other end of the fastener confined within a corresponding structure on the middle frame.

[0113] Example 5

[0114] See Figures 1 to 12 As shown in the embodiment of this application, the bottom frame 11 of the battery box 100 is described in detail, which includes: a bottom peripheral frame, a high-voltage box 4, and a plurality of reinforcing beams 117. The bottom peripheral frame encloses to form a bottom cavity, the reinforcing beams 117 are located inside the bottom cavity, and both ends of the reinforcing beams 117 are respectively connected to the bottom peripheral frame. A cable passage 1173 is provided on the reinforcing beams 117. The high-voltage box 4 is located inside the bottom cavity, and the high-voltage box is located between two adjacent reinforcing beams 117. The high-voltage box 4 is connected to two reinforcing beams 117, and a cable is connected to the high-voltage box 4, with the cable passing through the cable passage 1173.

[0115] like Figure 8 As shown, this application provides a reinforcing beam 117 in the bottom cavity of the bottom frame 11, which enhances the strength of the bottom peripheral frame structure and facilitates the installation of the high voltage box 4. The reinforcing beam 117 is provided with a wire passage 1173, which facilitates the lead wire from the high voltage box 4 to the outside. The reinforcing beam 117 will not interfere with the electrical connection between the high voltage box 4 and other external devices.

[0116] In some possible implementations, the reinforcing beams 117 on both sides of the high-voltage box 4 are provided with cable passages 1173. Cables are connected to both sides of the high-voltage box 4, and the cables on both sides extend through the corresponding cable passages 1173. The cables on both sides of the high-voltage box 4 can pass smoothly through the cable passages 1173 on the corresponding reinforcing beams 117, making cable arrangement convenient and neat. In addition to strengthening the structural strength of the bottom frame 11, the two reinforcing beams 117 also serve to connect and fix the high-voltage box 4.

[0117] In some possible implementations, the reinforcing beam 117 includes an outer shell wall and a plurality of reinforcing ribs. The outer shell wall has a shell cavity, and each reinforcing rib is disposed within the shell cavity and connected to the inner wall of the outer shell wall.

[0118] The reinforcing beam 117 has multiple reinforcing ribs inside, forming numerous hollow cavities between adjacent ribs or between the ribs and the outer shell wall. This reduces weight, while the multiple ribs increase the structural strength of the reinforcing beam 117, preventing it from easily deforming. The reinforcing beam 117 can be made of aluminum profile. The bottom peripheral frame can also be made of aluminum profile.

[0119] In some possible implementation schemes, combined Figure 8 As shown, the bottom frame 11 of the battery box 100 includes a sealing plate 1174, a reinforcing beam 117 which is plate-shaped, and a cable passage 1173 that extends through the reinforcing beam 117 along its thickness direction. The sealing plate 1174 covers the thickness end face of the cable passage 1173 of the reinforcing beam 117, thereby sealing the cavity located on one side of the cable passage 1173. The sealing plate 1174 not only enhances the structural strength of the reinforcing beam 117, but also covers the side of the cavity of the bottom frame 11 near the cable passage 1173, preventing external impurities from entering the cavity through the cable passage 1173 and making cleaning difficult. Simultaneously, the sealing plate 1174 can make smooth contact with the cable, preventing the cable from being cut or damaged by the outer casing wall.

[0120] In some possible implementations, the sealing plate 1174 includes two longitudinal plates 11741 and two transverse plates 11742. The two longitudinal plates 11741 are located on both sides of the cable passage 1173 along the horizontal direction, and the two transverse plates 11742 are located on both sides of the cable passage 1173 along the vertical direction. The longitudinal plates 11741 are smoothly connected to the two transverse plates 11742. The smooth connection of the two longitudinal plates 11741 and the two transverse plates 11742 forms a closed loop, which facilitates cable passage and prevents cable damage.

[0121] In some possible implementations, both ends of the longitudinal sheet 11741 along the height direction are provided with curved pieces, and the curved pieces are smoothly connected to the transverse sheet 11742. The longitudinal sheet 11741 has the function of supporting the reinforcing beam 117 along the longitudinal (height direction), which helps to enhance the structural strength of the reinforcing beam 117 at the wiring opening 1211 and reduce or avoid deformation of the reinforcing beam 117.

[0122] In some possible implementations, adapter frames are connected to both sides of the high-voltage box 4, and the adapter frames on both sides of the high-voltage box 4 are respectively connected to the corresponding reinforcing beams 117 by fasteners. The high-voltage box 4 of this application is installed from the bottom side of the bottom frame 11. By adding adapter frames to both sides of the high-voltage box 4, the high-voltage box 4 can be easily installed on the two reinforcing beams 117. The adapter frames can be bolted to the reinforcing beams 117.

[0123] In some possible implementations, such as Figure 3 As shown, the bottom frame 11 may include a precision positioning device 111, which is located within the right angle formed between the reinforcing beam 117 and the bottom peripheral frame, and is fixed to the reinforcing beam 117. The precision positioning device 111 is provided with a positioning groove.

[0124] When the battery box 100 with the bottom frame 11 is placed on the battery box base 200, the guide post on the battery box base 200 can be inserted into the positioning groove to achieve precise positioning of the battery box 100.

[0125] In some possible implementations, a locking groove 1153 is provided on the bottom peripheral frame. When the battery box 100 with the bottom frame 11 is unloaded onto the battery box base 200, the locking tongue 210 of the locking mechanism on the battery box base 200 can be inserted into the locking groove 1153 to fix the bottom frame 11 of the battery box 100.

[0126] The battery box 100 provided in this embodiment includes a top frame 12, a middle frame 13, and a bottom frame 11. The top frame 12 is located on top of the bottom frame 11, and the middle frame 13 is located between the bottom frame 11 and the top frame 12. The middle frame 13 connects the top frame 12 and the bottom frame 11, forming a battery mounting space between the top frame 12 and the bottom frame 11. The battery pack 2 is disposed within the battery mounting space, and the cables of the high-voltage box 4 are electrically connected to the battery pack 2. Through the above structural design, the bottom frame 11 is sufficient to bear the weight of the battery pack 2 and the top frame 12, and the frame 1 of the battery box 100 has high structural strength, good stability, and durability.
