[0013] Compared with related technologies, this application has the following advantages: (1) The battery pack housing structure described in this application comprises a housing body, a cover plate, and a connecting portion between the two. The housing body has an open-end cavity and a mounting portion for mounting the housing body onto an external carrier. The cover plate can seal the opening of the cavity, and the connecting portion can connect the cover plate to the housing body. The connection between the cover plate and the housing can be completed without tools, simply by sliding and snapping together, facilitating the installation of the cover plate and the housing body. Simultaneously, the elastic element continuously pushes the connecting block into the connecting groove, preventing loosening due to vibration or impact, thus improving the reliability of the connection between the cover plate and the housing body.

[0014] (2) By setting a cavity-filled insert at the bottom of the connecting post, and the connecting block slidingly mounted on the insert and extending out of the cavity, with the elastic element located inside the cavity, a stable sliding guide can be provided for the connecting block, reducing jamming during the sliding process and facilitating the installation of the cover plate. At the same time, the cavity can also constrain the position of the elastic element, limiting its offset or tilt in the non-working direction, which is beneficial to improving the connection reliability between the cover plate and the housing body.

[0015] (3) The connecting block includes a column inserted into the block and a clamp head located at one end of the column. The groove wall of the connecting groove is provided with a groove adapted to the clamp head. Under the push of the elastic element, the clamp head is locked in the groove, which can limit the displacement of the connecting block in the height direction of the battery pack housing structure and improve the reliability of the cover plate connection. At the same time, the elastic element can continuously push the clamp head to fit against the inner wall of the groove, which can prevent the column from falling out of the groove due to vibration or impact, which is conducive to further improving the reliability of the cover plate connection.

[0016] (4) By setting a mounting block on the base plate and a mounting cavity on the mounting block, the mounting part includes a clamping plate located in the mounting cavity and a locking pin connected to the clamping plate and screwed onto the mounting cavity. The housing body can be clamped onto the external carrier by the clamping plate and the mounting block. Its structure is simple and the connection is reliable. The clamping force of the clamping plate can be adjusted by the locking pin, and the fixing strength can be controlled according to the requirements to avoid displacement of the housing due to vibration and bumps, thereby improving the fixing reliability of the battery pack housing structure. At the same time, it can achieve stepless adjustment, so as to adapt to external carriers of different thicknesses.

[0017] (5) By setting a fixing block on the top of the base plate and setting a connecting groove on the fixing block and an operating hole connected to the connecting groove, the operating hole is set in correspondence with the connecting block. A tool can be inserted through the operating hole to push the connecting block to compress the elastic element, thereby realizing the disassembly of the cover plate and the housing, which facilitates the disassembly of the cover plate.

[0018] (6) The projection of the main body in its own height direction is located within the projection of the cover plate. The cover plate can completely cover the opening edge and surrounding area of ​​the main body, preventing dust and rainwater from seeping into the cavity from the gap between the main body and the cover plate, which is conducive to improving the sealing of the battery pack.

[0019] (7) By providing a wiring section on the cover plate for arranging the wiring harness of the battery pack, it is possible to avoid the wiring harness from being tangled in the battery pack, reduce the damage to the insulation layer caused by the wire harness due to compression and friction, reduce the risk of short circuit, and improve the reliability of the battery pack.

[0020] (8) The cable routing section includes a cable routing drum mounted on the cover plate. The cable routing drum can isolate the cable harness from external dust and moisture, prevent the insulation layer of the cable harness from being damaged due to friction, and reduce the risk of short circuit. Multiple cable routing rollers are spaced apart inside the cable routing drum, as well as tension roller assemblies between two adjacent cable routing rollers. These assemblies can guide the direction of the cable harness and compensate for tension fluctuations caused by temperature changes or vibrations. This prevents the cable harness from shaking and tangling due to being too loose, or from breaking due to being too tight, thus ensuring transmission stability.

[0021] (9) The tensioning wheel assembly includes an adjusting post screwed onto the cable reel, a mounting post on the adjusting post, and a tensioning wheel on the mounting post. The adjusting post has an adjusting end located outside the cable reel and a mounting end extending into the cable reel. The mounting post is rotatably mounted on the mounting end, which facilitates the adjustment of the tension of the cable harness, thereby adapting to cable harnesses of different lengths and with different tension requirements. At the same time, the adjusting post screwed onto the cable reel can also achieve stepless adjustment, thereby adjusting and controlling the displacement of the tensioning wheel, avoiding over- or under-tension adjustment, which is beneficial to improving the reliability of the battery pack.

[0022] Another object of this application is to provide a battery pack having a battery pack housing structure as described in any one of the above descriptions.

[0023] The battery pack described in this application, by providing the battery pack housing structure as described in any one of the above-mentioned methods, facilitates the installation and disassembly of the battery pack, thereby improving the production efficiency and maintenance convenience of the battery pack. It also enhances the reliability of the battery pack. Attached Figure Description

[0025] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a battery pack housing structure disposed within a battery pack, which, through its innovative structural design, facilitates the installation of the battery pack housing.

[0032] In related technologies, against the backdrop of the rapid development of new energy technologies, battery packs, as core components of energy storage, are widely used in new energy vehicles, portable energy storage devices, smart homes, and other fields. The battery pack casing, as a key structure protecting the internal cells, circuits, and other core components, directly affects the safety, reliability, and lifespan of the battery pack. However, traditional battery pack casing designs generally suffer from difficulties in assembly.

[0033] In view of this, in order to overcome the shortcomings of the related technology, the battery pack housing structure of this embodiment combines... Figures 1 to 6 In terms of overall design, it includes a housing body 100, a cover plate 200, and a connecting part 400 between the two.

[0034] The housing body 100 has a receiving cavity with an opening at one end, and a mounting part 300 is provided on the housing body 100 for mounting the housing body 100 on an external carrier. The connecting part 400 can connect the cover plate 200 to the housing body 100 and block the opening of the receiving cavity with the cover plate 200. The connecting part 400 includes a connecting groove 4011 provided on the housing body 100, a connecting block 403 slidably provided on the cover plate 200, and an elastic member 404 provided between the connecting groove 4011 and the connecting block 403. Under the push of the elastic member 404, the connecting block 403 can be engaged in the connecting groove 4011.

[0035] Therefore, by providing a housing body 100, a cover plate 200, and a connecting portion 400 between them, and by providing a receiving cavity with one open end on the housing body 100, and a mounting portion 300 for mounting the housing body 100 on an external carrier, and by enabling the cover plate 200 to seal the opening of the receiving cavity, and by enabling the connecting portion 400 to connect the cover plate 200 to the housing body 100 together, the connection between the cover plate 200 and the housing can be completed without tools, simply by sliding and snapping together, which facilitates the installation of the cover plate 200 and the housing body 100 and helps to improve production efficiency. At the same time, the elastic element 404 continuously pushes the connecting block 403 into the connecting groove 4011, which can prevent loosening caused by vibration or impact, and helps to improve the connection reliability between the cover plate 200 and the housing body 100.

[0036] Based on the above general introduction, specifically, the housing body 100 and related structures not mentioned in this embodiment can refer to the related structures of battery housings known to those skilled in the art, and this embodiment does not make any improvements thereto.

[0037] Furthermore, it is worth mentioning that the external carrier described in this embodiment can be a vehicle, as is well known to those skilled in the art. Of course, it is not limited to vehicles; it can also be installed in carriers or equipment such as energy storage power stations, outdoor monitoring equipment, and conveyor belt supports of automated production lines, which will not be elaborated upon here.

[0038] Combination Figures 1 to 4 As shown, in some exemplary embodiments, the cover plate 200 includes a cover plate body 201 for sealing the opening, a connecting post 202 disposed on the cover plate body 201, and an insert block 402 disposed at the bottom of the connecting post 202. The insert block 402 has a cavity, the connecting block 403 is slidably disposed on the insert block 402 and extends out of the cavity, and the elastic member 404 is disposed in the cavity.

[0039] This design provides a stable sliding guide for the connecting block 403, reducing jamming during sliding and facilitating the installation of the cover plate 200. Simultaneously, the cavity also constrains the position of the elastic element 404, limiting its offset or tilting in non-working directions, which helps improve the reliability of the connection between the cover plate 200 and the housing body 100.

[0040] In specific implementation, the connecting posts 202 in this embodiment are located on both sides of the cover plate body 201 in the width direction, and are spaced apart along the length direction of the cover plate body 201. Preferably, three are spaced apart along the length direction of the cover plate body 201 to ensure the reliability of the connection between the cover plate body 201 and the housing body 100 while reducing costs. Of course, the specific number and arrangement of the connecting posts 202 in this embodiment can be adapted to the actual situation, and will not be elaborated here. In addition, it is worth mentioning that the above-mentioned elastic element 404 can be a spring well known to those skilled in the art, and will not be described in detail here.

[0041] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, the connecting block 403 includes a post 4031 inserted into the insert block 402, and a locking head 4032 disposed at one end of the post 4031. The groove wall of the connecting groove 4011 is provided with a groove 4012 adapted to the locking head 4032, and the locking head 4032 is engaged in the groove 4012 under the pushing of the elastic member 404.

[0042] The advantage of this design is that it can limit the displacement of the connecting block 403 in the height direction of the battery pack housing structure, thereby improving the reliability of the cover plate 200 connection. At the same time, the elastic element 404 can continuously push the clip 4032 to fit against the inner wall of the groove 4012, which can prevent the column 4031 from falling out of the groove 4012 due to vibration or impact, further improving the reliability of the cover plate 200 connection.

[0043] In specific implementation, the card head 4032 is mushroom-shaped and can be made of silicone material familiar to those skilled in the art. In this way, the elasticity and deformation ability of silicone can be utilized so that when the card head 4032 is engaged with the groove 4012, it can fit tightly against the inner wall of the groove 4012 through its own slight deformation, thereby improving the reliability of the engagement and preventing the cover plate 200 from shifting due to vibration or impact.

[0044] Combination Figure 1 as well as Figure 5 As shown, in some exemplary embodiments, the housing body 100 includes a main body 101 with a receiving cavity, a base plate 102 disposed at the bottom of the main body 101, and a mounting block 103 disposed on the base plate 102. The mounting block 103 has a mounting cavity, and the mounting part 300 includes a clamping plate 301 disposed in the mounting cavity, and a locking pin 302 connected to the clamping plate 301 and screwed to the mounting cavity. The housing body 100 can be clamped to an external carrier by the clamping plate 301 and the mounting block 103.

[0045] This design allows for a simple and reliable connection of the mounting block 103, and the clamping force of the clamping plate 301 can be adjusted via the locking pin 302. The fixing strength can be controlled as needed, preventing displacement of the casing due to vibration or bumps, thus improving the fixing reliability of the battery pack casing structure. Furthermore, it allows for stepless adjustment, enabling it to adapt to external carriers of varying thicknesses.

[0046] In specific implementation, the mounting blocks 103 of this embodiment are located on both sides of the base plate 102 along its length, and two sets are arranged at intervals along the width of the base plate 102. Each set includes a pair of mounting blocks 103 corresponding to each other on both sides of the base plate 102 along its length. Of course, there can also be three, four or more sets. The specific number and arrangement can be adjusted according to the actual situation, which will not be elaborated here. However, as the number increases, the manufacturing cost may increase and the installation of the mounting blocks 103 with the external carrier may become more difficult.

[0047] In this embodiment, the mounting block 103 has one end connected to the base plate 102, and the other end is provided with a threaded through hole 1031 for the locking pin 302 to pass through, a threaded sleeve 305 coaxially arranged with the threaded through hole 1031 for guiding the locking pin 302, and a locking nut 303 located outside the mounting cavity and screwed onto the locking pin 302. The locking pin 302 includes a locking pin body 3021, a first protrusion 3022 located at the end of the locking pin body 3021 connected to the clamping plate 301 and protruding radially along the locking pin body 3021, and a pressure plate 304 screwed to the clamping plate 301. The pressure plate 304 has a cavity for accommodating the first protrusion 3022 and a first connecting through hole that cooperates with the locking pin body 3021 for the locking pin 3021 to pass through. In this way, the locking pin 302 and the clamping plate 301 can be rotated together, thereby enabling the adjustment of the clamping plate 301.

[0048] Additionally, it should be mentioned that the external carrier described in this embodiment can be a vehicle, test bench, or other similar device familiar to those skilled in the art, and will not be described in detail here.

[0049] Combination Figures 3 to 4 As shown, in some exemplary embodiments, the housing body 100 includes a fixing block 401 disposed on the top of the base plate 102. The fixing block 401 is provided with a connecting groove 4011 and an operating hole 4013 communicating with the connecting groove 4011, and the operating hole 4013 is correspondingly disposed with the connecting block 403. The advantage of this arrangement is that a tool can be inserted through the operating hole 4013 to push the connecting block 403 to compress the elastic member 404, thereby realizing the disassembly of the cover plate 200 from the housing, which facilitates the disassembly of the cover plate 200.

[0050] In specific implementation, the fixing block 401 in this embodiment is correspondingly set with the connecting column 202. The specific number and arrangement can be referred to the number and arrangement of the connecting column 202 mentioned above, and will not be repeated here.

[0051] Combination Figure 1 As shown, in some exemplary embodiments, the projection of the body 101 in its height direction lies within the projection of the cover 200. This arrangement allows the cover 200 to completely cover the opening edge and surrounding area of ​​the body 101, preventing dust and rainwater from seeping into the receiving cavity through the gap between the body 101 and the cover 200, thus improving the battery pack's sealing performance.

[0052] Combination Figure 1 As shown, in some exemplary embodiments, the cover plate 200 is provided with a wiring section 500 for arranging the wiring harness of the battery pack. This prevents the wiring harness from becoming tangled and messy within the battery pack, reduces insulation damage caused by compression and friction, lowers the risk of short circuits, and improves the reliability of the battery pack.

[0053] In a specific implementation, the wiring section 500 of this embodiment is disposed on the wiring section bracket 203. The wiring section bracket 203 includes a first extension section 2031 extending away from the cover plate 200 at one end along the length direction of the cover plate 200, and a second extension section 2032 disposed at the end of the first extension section 2031 away from the cover plate 200 and extending along the height direction of the battery pack housing structure. The wiring section 500 is disposed at the end of the second extension section 2032 away from the first extension section 2031 and extends along the length direction of the battery pack housing structure.

[0054] Furthermore, in this embodiment, the wiring sections 500 are located on both sides of the battery pack housing structure along its length, and three sets are arranged at intervals along the width of the battery pack housing structure. Each set includes a pair of wiring sections 500 correspondingly located on both sides of the base plate 102 along its length. Of course, there can also be two, four, five, or more sets. The specific number and arrangement can be adjusted according to the actual situation, and will not be elaborated here. However, as the number increases, the manufacturing cost may rise.

[0055] Combination Figure 6 As shown, in some exemplary embodiments, the cable section 500 includes a cable reel 501 disposed on the cover plate 200, a plurality of cable pulleys 502 spaced apart within the cable reel 501, and a tensioning pulley assembly 503 disposed between two adjacent cable pulleys 502.

[0056] Thus, by setting up the cable tray 501, external dust and moisture can be isolated from the corrosion of the wire harness, preventing damage to the insulation layer caused by friction and reducing the risk of short circuits. Multiple cable guide rollers 502 are spaced apart inside the cable tray 501, and a tensioning roller assembly 503 is located between adjacent cable guide rollers 502. This guides the wire harness and compensates for tension fluctuations caused by temperature changes or vibrations, preventing the wire harness from shaking and tangling due to excessive looseness or breaking due to excessive tightness, thus ensuring transmission stability.

[0057] In detail, the cable guide rollers 502 in this embodiment include two arranged at intervals along the axial direction of the cable guide tube 501, and a tensioning roller assembly 503 is provided between the two cable guide roller 502 assemblies. Of course, in specific implementations, the number of cable guide rollers 502 in this embodiment can also be three, four or more, and the specific number can be adaptively adjusted according to actual usage needs. However, more cable guide rollers 502 may lead to a more complex cable guide section 500 structure and an increase in the cost of the battery pack housing structure.

[0058] The tensioning wheel assembly 503 includes an adjusting post 5031 screwed onto the cable reel 501, a mounting post 5032 rotatably mounted on the adjusting post 5031, and a tensioning wheel 5033 rotatably mounted on the mounting post 5032. The adjusting post 5031 has an adjusting end 50311 located outside the cable reel 501 and a mounting end 50312 extending into the cable reel 501. The mounting post 5032 is rotatably mounted on the mounting end 50312.

[0059] This design facilitates tension adjustment of the wiring harness, adapting to harnesses of different lengths and tension requirements. Simultaneously, the adjusting pin 5031, screwed onto the cable reel 501, can also adjust and control the displacement of the tensioning wheel 5033, preventing over- or under-tension adjustment and improving battery pack reliability.

[0060] In specific implementation, the adjusting end 50311 of this embodiment is located at the end of the adjusting column 5031 away from the cable tray 501, and the diameter of the adjusting end 50311 is larger than the diameter of the mounting end 50312, so as to facilitate the adjustment of the adjusting column 5031 and to limit the adjustment column 5031, preventing the adjusting column 5031 from falling into the cable tray 501. In addition, the mounting column 5032 in this embodiment has a circular cross-section and is screwed to the adjusting column 5031. The middle of the end of the two mounting columns 5032 away from the adjusting column 5031 is provided with a receiving groove for accommodating the tensioning wheel 5033. The receiving groove is arranged in the radial direction of the mounting column 5032 and extends in the axial direction of the mounting column 5032. The end of the mounting column 5032 away from the adjusting column 5031 is provided with a rotating shaft, and the tensioning wheel 5033 is rotatably mounted on the rotating shaft.

[0061] It is worth noting that, regarding the battery pack housing structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 6 As shown, it may include, for example, a housing body 100, a cover plate 200, and a connecting portion 400 disposed between the two.

[0062] The housing body 100 has a receiving cavity with an opening at one end, and a mounting part 300 is provided on the housing body 100 for mounting the housing body 100 on an external carrier. The connecting part 400 can connect the cover plate 200 to the housing body 100 and block the opening of the receiving cavity with the cover plate 200. The connecting part 400 includes a connecting groove 4011 provided on the housing body 100, a connecting block 403 slidably provided on the cover plate 200, and an elastic member 404 provided between the connecting groove 4011 and the connecting block 403. Under the push of the elastic member 404, the connecting block 403 can be engaged in the connecting groove 4011.

[0063] The cover plate 200 includes a cover plate body 201 for sealing the opening, a connecting post 202 disposed on the cover plate body 201, and an insert block 402 disposed at the bottom of the connecting post 202. The insert block 402 has a cavity, and a connecting block 403 is slidably disposed on the insert block 402 and extends out of the cavity. An elastic member 404 is disposed in the cavity.
