[0002] In power battery modules, the output terminal base is a key component at the high-voltage output terminal, and its stability is paramount. During battery pack use, the output terminal base must fit tightly with related components to ensure that the output terminal of the battery module does not experience short circuits or other malfunctions when the vehicle is subjected to impacts and vibrations. In traditional output terminal base fixing schemes, the structure of the output terminal base and module end plate is complex, the installation operation is relatively complicated, and the connection stability is poor, making it difficult to cope with impact and vibration conditions. Utility Model Content

[0003] In view of this, this application aims to provide an output electrode base mounting structure to facilitate the installation of the output electrode base and to provide good installation stability.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: An output electrode base mounting structure is suitable for mounting an output electrode base on a module end plate, including an insertion part and a snap-fit ​​part disposed between the module end plate and the output electrode base; The insertion part can insert the output electrode base and the module end plate together in the first direction, and at least restrict the displacement of the output electrode base in the second direction. As the output electrode base and the module end plate are inserted, the snap-fit ​​part can snap the output electrode base and the module end plate together, and restrict the displacement of the output electrode base in the first direction.

[0005] Furthermore, the insertion part includes a mounting groove at one end of the module end plate and a plug on the output electrode base; the side wall of the mounting groove is provided with a slot extending along the first direction, and the plug is inserted into the slot.

[0006] Furthermore, one end of the module end plate is provided with two mounting blocks arranged opposite to each other, and the mounting groove is formed by the two mounting blocks; each of the two mounting blocks is provided with the slot, and the two opposite ends of the output electrode base are provided with the insertion block.

[0007] Furthermore, the insert includes a connecting arm cantilevered on the output electrode base, and a protrusion at the free end of the connecting arm, the protrusion protruding outward from the output electrode base along the second direction, the protrusion being inserted into the slot; and / or, at least one of the mounting blocks is provided with a limiting block, the limiting block being used to restrict the insert from dislodging from the slot along the first direction.

[0008] Furthermore, the snap-fit ​​portion includes a snap-fit ​​groove disposed at the bottom of the mounting slot and a snap-fit ​​block disposed at the bottom of the output electrode base; in the first direction, the snap-fit ​​groove is flush with the end of the slot.

[0009] Furthermore, the output electrode base includes a base body and a protective cover covering the base body; the insertion part and the snap-fit ​​part are both located between the base body and the protective cover.

[0010] Furthermore, a first insertion structure and a second insertion structure are provided between the protective cover and the base body; the first insertion structure connects the protective cover to the base body along the first direction, and the second insertion structure connects the inserted protective cover to the base body along a third direction.

[0011] Furthermore, the first insertion structure includes a post disposed on the top of the base body and an insertion groove disposed on the protective cover; the post is interference-fitted into the insertion groove and can restrict the protective cover from being dislodged from the base body in the third direction.

[0012] Furthermore, the second insertion structure includes an insertion protrusion on the base body and an insertion hole on the protective cover; the insertion protrusion and the insertion post are respectively located at both ends of the base body in the second direction, and the insertion protrusion is inserted into the insertion hole.

[0013] Compared with the prior art, this application has the following advantages: (1) The output electrode base mounting structure of this application provides an insertion part and a snap-fit ​​part between the module end plate and the output electrode base, and the insertion part can insert the output electrode base and the module end plate together in the first direction, and at least limit the displacement of the output electrode base in the second direction. As the output electrode base and the module end plate are inserted, the snap-fit ​​part can snap the output electrode base and the module end plate together, and limit the displacement of the output electrode base in the first direction, so that the output electrode base can be convenient to install and also has good installation stability.

[0014] (2) The insertion part includes a mounting groove at one end of the module end plate and an insertion block on the output electrode base. The side wall of the mounting groove is provided with a slot extending in the first direction, and the insertion block is inserted into the slot. This structure is simple, easy to design and implement, and thus helps to improve production efficiency.

[0015] (3) Two mounting blocks are arranged opposite each other at one end of the module end plate. The mounting groove is formed by the two mounting blocks. Each mounting block is provided with a slot. Each opposite end of the output electrode base is provided with a plug. The mounting blocks facilitate the construction of the mounting groove on the module end plate. At the same time, the slots on both mounting blocks and the plugs on each opposite end of the output electrode base can avoid structural deformation or damage caused by excessive force on one side, thereby improving the reliability of the output electrode mounting structure.

[0016] (4) The insert includes a connecting arm cantilevered on the output electrode base and a protrusion at the free end of the connecting arm. The protrusion protrudes outward from the output electrode base in a second direction and is inserted into a slot. At least one mounting block has a limiting block for limiting the insert from exiting the slot in a first direction. Thus, the connecting arm cantilevered on the output electrode base has a certain elasticity, allowing the protrusion to abut tightly against the side wall of the slot, thereby ensuring the limiting of the output electrode base and the module end plate in a third direction, and thus improving the connection stability between the module end plate and the output electrode base. At the same time, the connecting arm can also absorb a certain amount of vibration and impact, making the connection between the output electrode base and the module end plate more stable. The limiting block on the mounting block can limit the insert from exiting the slot in the first direction while also facilitating the installation and positioning of the insert.

[0017] (5) The snap-fit ​​part includes a snap-fit ​​groove at the bottom of the mounting slot and a snap-fit ​​block at the bottom of the output electrode base. In the first direction, the snap-fit ​​groove is flush with the end of the slot. This structure is simple and easy to design and implement. By setting the snap-fit ​​groove and the end of the slot flush, the snap-fit ​​structure can be realized at the end of the insertion path, which can have a better installation effect and can prevent over-insertion, which would make it difficult to achieve snap-fit. The snap-fit ​​groove structure is simple and easy to install, which can reduce the installation difficulty and help improve production efficiency.

[0018] (6) The output terminal base includes a base body and a protective cover covering the base body. The insertion part and the snap-fit ​​part are both located between the base body and the protective cover. In this way, by setting a protective cover covering the base body, the output terminal electrical connector can be isolated from the outside, preventing short circuits and leakage, which is beneficial to improving the safety of the battery pack. At the same time, the protective cover can effectively prevent dust and other impurities from entering the interior of the output terminal base, protecting the internal components from corrosion, extending their service life, and also preventing damage to the internal components caused by vibration or external impact, further improving its safety.

[0019] (7) A first insertion structure and a second insertion structure are provided between the protective cover and the base body. The first insertion structure connects the protective cover to the base body along a first direction, and the second insertion structure connects the inserted protective cover to the base body along a third direction. In this way, by setting the first and second insertion structures, the reliability of the connection between the protective cover and the base body can be ensured, and the displacement of the protective cover due to impact or vibration can be avoided, thereby improving the safety of the battery pack. At the same time, the insertion structure is simple to install and easy to operate, which also helps to improve production and assembly efficiency.

[0020] (8) The first plug-in structure includes a plug post located on the top of the base body and a plug-in groove located on the protective cover. The plug post is interference-fitted into the plug-in groove and can prevent the protective cover from dislodging from the base body in a third direction. With this configuration, the plug post and the plug-in groove are interference-fitted, which can effectively prevent loosening caused by vibration or external force and ensure the reliability of the connection between the protective cover and the base body in a third direction. At the same time, the plug-in structure is easy to install and also helps to improve production efficiency.

[0021] (9) The second insertion structure includes an insertion protrusion on the base body and an insertion hole on the protective cover. The insertion protrusion and the insertion post are respectively located at both ends of the base body in the second direction, and the insertion protrusion is inserted into the insertion hole. In this way, the insertion protrusion is inserted into the insertion hole, so that the second insertion structure can limit the protective cover in one direction, ensuring the reliability of the connection between the protective cover and the base body in the first direction. The insertion protrusion and the insertion post are respectively located at both ends of the base body in the second direction, which can realize the limitation of the protective cover and the base body in the second direction, thereby further ensuring the reliability of the connection between the protective cover and the base body, avoiding the displacement of the protective cover due to impact or vibration, and thus helping to improve the safety of the battery pack.

[0022] This application also proposes a battery pack, which has an output terminal base mounting structure as described above.

[0023] The battery pack of this application, by setting the output terminal base mounting structure as described above, enables the output terminal base to effectively withstand impact and vibration conditions, thereby improving the connection stability between the module end plate and the output terminal base, reducing the risk of loose electrical connections or short circuits caused by vibration, and thus improving the reliability and safety of the entire battery pack. At the same time, the aforementioned output terminal base mounting structure also simplifies the installation process of the output terminal base, thereby improving production efficiency and facilitating the large-scale application of the battery pack.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. 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 an output electrode base mounting structure, which is suitable for mounting the output electrode base on a module end plate. It is mainly used to connect the output electrode base and the module end plate. Furthermore, the output electrode base mounting structure of this embodiment utilizes its innovative structural design to make the output electrode base easy to install while also effectively coping with impact and vibration conditions, thereby improving the connection stability between the module end plate and the output electrode base.

[0032] In power battery modules, the output terminal base is a key component at the high-voltage output terminal, and its stability is paramount. During battery pack use, the output terminal base must fit tightly with related components to ensure that the output terminal of the battery module does not experience short circuits or other malfunctions when the vehicle is subjected to impacts and vibrations. In traditional output terminal base fixing schemes, the structure of the output terminal base and module end plate is complex, the installation operation is relatively complicated, and the connection stability is poor, making it difficult to cope with impact and vibration conditions.

[0033] In view of this, in order to overcome the shortcomings of the prior art, in the output electrode base 2 mounting structure of this embodiment, which is suitable for mounting the output electrode base 2 on the module end plate 1, combined with Figures 1 to 8 As shown, the overall design includes an insertion part and a snap-fit ​​part located between the module end plate 1 and the output electrode base 2.

[0034] The insertion part can insert the output electrode base 2 and the module end plate 1 together in the first direction, and at least restrict the displacement of the output electrode base 2 in the second direction. As the output electrode base 2 and the module end plate 1 are inserted, the snap-fit ​​part can snap the output electrode base 2 and the module end plate 1 together, and restrict the displacement of the output electrode base 2 in the first direction.

[0035] Therefore, by providing an insertion part and a snap-fit ​​part between the module end plate 1 and the output electrode base 2, the insertion part can insert the output electrode base 2 and the module end plate 1 together in the first direction and at least limit the displacement of the output electrode base 2 in the second direction. As the output electrode base 2 and the module end plate 1 are inserted, the snap-fit ​​part can snap the output electrode base 2 and the module end plate 1 together and limit the displacement of the output electrode base 2 in the first direction. Thus, the output electrode base 2 can be installed conveniently while also having good installation stability.

[0036] Based on the above general introduction, specifically, the module end plate 1 in this embodiment is manufactured by die casting. The specific material selection, as well as other related structures in the module end plate 1 not mentioned in this embodiment, can all refer to the relevant structures in the existing module end plate 1, and will not be described in detail here.

[0037] Combination Figure 1 , Figure 2 , Figure 4 as well as Figure 6As shown, in some exemplary embodiments, the module end plate 1 is rectangular, with a first direction parallel to its thickness, a second direction parallel to its length, and a third direction parallel to its height. The insertion part includes a mounting groove 11 at one end of the module end plate 1 and an insertion block 211 on the output electrode base 2. A slot 11111 extending along the first direction is provided on the side wall of the mounting groove 11, and the insertion block 211 is inserted into the slot 11111. This structure is simple, easy to design and implement, and thus helps improve production efficiency.

[0038] Continue to combine Figure 1 , Figure 2 , Figure 4 as well as Figure 6 As shown, in some exemplary embodiments, one end of the module end plate 1 is provided with two mounting blocks 1111 arranged opposite each other, and the mounting groove 11 is formed by the two mounting blocks 1111. Each of the two mounting blocks 1111 has a slot 11111, and each of the two opposite ends of the output electrode base 2 has a plug 211. Thus, it can be understood that the mounting blocks facilitate the construction of the mounting groove on the module end plate. At the same time, the slots 11111 on both mounting blocks 1111 and the plugs 211 at each of the two opposite ends of the output electrode base 2 can prevent structural deformation or damage caused by excessive force on one side, thereby improving the reliability of the output electrode mounting structure.

[0039] In practical implementation, the insertion block 211 and the mounting block 1111 can not only be set on two opposite sides of the output electrode base 2, but their number is also not limited to two; there can be three, four, or more. Different numbers and arrangements can be designed according to requirements, as long as they can fix the output electrode base 2 on the module end plate 1.

[0040] Combination Figures 6 to 7 As shown, in some exemplary embodiments, the plug 211 includes a connecting arm 2111 cantilevered on the output electrode base 2 and a protrusion 2112 at the free end of the connecting arm 2111. The protrusion 2112 protrudes outward from the output electrode base 2 in a second direction and is inserted into the slot 11111.

[0041] Thus, the connecting arm 2111, cantilevered on the output electrode base 2, possesses a certain degree of elasticity, allowing the protrusion 2112 to tightly abut against the side wall of the slot 11111. This helps ensure the limiting position of the output electrode base 2 and the module end plate 1 in the third direction, thereby improving the connection stability between the module end plate 1 and the output electrode base 2. Simultaneously, the connecting arm 2111 can absorb some vibration and impact, making the connection between the output electrode base 2 and the module end plate 1 more stable. In specific implementation, such as... Figure 7 As shown, in this embodiment, the connecting arm 2111 is U-shaped, with one end connected to the output electrode base 2 and integrally formed with it. The free end has a protrusion 2112 extending outwards from the output electrode base 2 along a second direction. Thus, the U-shaped connecting arm 2111 has a certain degree of elasticity, capable of absorbing some vibration and impact, making the connection between the output electrode base 2 and the module end plate 1 more stable. The integral forming method also reduces the risk of structural damage due to fatigue at the connection point, improves the fatigue resistance of the entire structure, and extends its service life. It should be noted that the connecting arm 2111 in this embodiment can be not only U-shaped, but also other elastic cantilever arms that can achieve the same function; further details will not be provided here.

[0042] At least one of the mounting blocks 1111 is provided with a limiting block 11112, which is used to restrict the insertion block 211 from dislodging from the slot 11111 in the first direction. In this way, the limiting block 11112 on the mounting block 1111 can both restrict the insertion block 211 from dislodging from the slot 11111 in the first direction and facilitate the installation and positioning of the insertion block 211.

[0043] In detail, in this embodiment, at least one of the mounting blocks 1111 is provided with a limiting block 11112, meaning that the limiting block 11112 can be provided on either of the two mounting blocks 1111, or the limiting block 11112 can be provided on both mounting blocks 1111. Preferably, in the output electrode base 2 mounting structure of this embodiment, the limiting block 11112 is provided on both mounting blocks 1111.

[0044] Continue to combine Figure 4 And to Figure 7 As shown, in some exemplary embodiments, the snap-fit ​​portion includes a snap-fit ​​groove 12 disposed at the bottom of the mounting groove 11 and a snap-fit ​​block 212 disposed at the bottom of the output electrode base 2, wherein in a first direction, the snap-fit ​​groove 12 is flush with the end of the slot 11111.

[0045] This design is simple and easy to implement. Aligning the ends of the snap-fit ​​groove 12 and the slot 11111 with each other allows for simultaneous snap-fit ​​at the end of the insertion path, resulting in better installation and preventing over-insertion that would hinder snap-fit. Furthermore, the snap-fit ​​groove 12's simple structure and ease of installation reduce installation difficulty and improve production efficiency.

[0046] In practical implementation, it should be noted that the number of the card slot 12 and the card block 212 can be designed and arranged in other directions according to the requirements, as long as the output pole base 2 can be fixed on the module end plate 1.

[0047] Combination Figures 5 to 8 As shown, in some exemplary embodiments, the output terminal base 2 includes a base body 21 and a protective cover 22 covering the base body 21. Both the insertion portion and the snap-fit ​​portion are located between the base body 21 and the protective cover 22. Thus, by providing the protective cover 22 covering the base body 21, the output terminal electrical connector can be isolated from the outside environment, preventing short circuits and leakage, which is beneficial to improving the safety of the battery pack. At the same time, the protective cover 22 can effectively prevent dust and other impurities from entering the interior of the output terminal base 2, protecting internal components from corrosion, extending their service life, and preventing damage to internal components due to vibration or external impact, further improving its safety.

[0048] Continue to combine Figures 5 to 8 As shown, in some exemplary embodiments, a first insertion structure and a second insertion structure are provided between the protective cover 22 and the base body 21. The first insertion structure connects the protective cover 22 to the base body 21 along a first direction, and the second insertion structure connects the inserted protective cover 22 to the base body 21 along a third direction. Thus, by providing the first and second insertion structures, the reliability of the connection between the protective cover 22 and the base body 21 can be ensured, preventing displacement of the protective cover due to impact or vibration, thereby improving the safety of the battery pack. At the same time, the insertion structure is simple to install and easy to operate, which also helps to improve production and assembly efficiency.

[0049] Combination Figure 5 , Figure 6 as well as Figure 8 As shown, in some exemplary embodiments, the first plug-in structure includes a plug 213 disposed on the top of the base body 21 and a plug groove 221 disposed on the protective cover 22. The plug 213 is interference-fitted into the plug groove 221 and is able to restrict the protective cover 22 from dislodging from the base body 21 in a third direction.

[0050] This design, with the insertion post 213 and the insertion slot 221 using an interference fit, effectively prevents loosening due to vibration or external force, ensuring the reliable connection between the protective cover 22 and the base body 21 in the third direction. At the same time, the insertion structure is easy to install and also helps improve production efficiency.

[0051] In specific implementation, the insertion post 213 located on the top of the base body 21 in this embodiment includes a first part 2131 connected to the base body 21, and a second part 2132 protruding radially along the insertion post 213. The second part 2132 is located at the end of the insertion post 213 away from the base body 21. When the insertion post 213 is interference-fitted into the insertion groove 221, the first part 2131 is interference-fitted with the insertion groove 221, and the second part 2132 can abut against the end face of the insertion groove 221 to prevent the protective cover 22 from dislodging from the base body 21 in a third direction. In addition, it should be noted that the insertion post 213 and the insertion groove 221 in this embodiment can also be designed in other forms, as long as the reliability of the connection between the protective cover and the base body 21 can be ensured, which will not be elaborated further.

[0052] Continue to combine Figure 5 , Figure 6 as well as Figure 8 As shown, in some exemplary embodiments, the second insertion structure includes an insertion protrusion 214 on the base body 21 and an insertion hole 222 on the protective cover 22. The insertion protrusion 214 and the insertion post 213 are respectively located at both ends of the base body 21 in the second direction, and the insertion protrusion 214 is inserted into the insertion hole 222.

[0053] Thus, the insertion protrusion 214 is inserted into the insertion hole 222, allowing the second insertion structure to limit the protective cover 22 in one direction, ensuring the reliability of the connection between the protective cover 22 and the base body 21 in the first direction. The insertion protrusion 214 and the insertion post 213 are respectively located at both ends of the base body 21 in the second direction, enabling the protective cover 22 and the base body 21 to be limited in the second direction, thereby further ensuring the reliability of the connection between the protective cover 22 and the base body 21, preventing displacement of the protective cover due to impact or vibration, and thus improving the safety of the battery pack.

[0054] In specific implementation, the insert protrusion 214 can be a wedge-shaped post to ensure the reliability of the connection between the protective cover 22 and the base body 21, reducing the risk of the protective cover 22 becoming dislodged due to impact or vibration, thus preventing safety hazards. The insert protrusion 214 can also be any design other than a wedge-shaped post, as long as it ensures the reliability of the connection between the protective cover and the base body 21.

[0055] In addition, it should be noted that the insertion protrusion 214 and the insertion post 213 in this embodiment can be two respectively located at both ends of the base body 21 in the second direction, or they can be arranged in different numbers and other directions according to the design, as long as the connection reliability between the protective cover and the base body 21 can be ensured.

[0056] In this embodiment, the output electrode base 2 mounting structure is specifically designed such that, during installation, the protrusion 2112 on the output electrode base 2 is inserted along the first direction into the slot 11111 on the mounting block 1111 until the protrusion 2112 abuts against the limiting block 11112 on the mounting block 1111. At this time, the snap-fit ​​block 212 on the output electrode base 2 will snap into the snap-fit ​​groove 12 on the module end plate 1, completing the connection between the output electrode base 2 and the module end plate 1.

[0057] When the protective cover 22 needs to be installed, the insertion slot 221 on the protective cover 22 is engaged with the insertion post 213 on the base body 21 along the first direction. At this time, the first part 2131 of the insertion post 213 is interference-fitted with the insertion slot 221, and the second part 2132 can abut against the end face of the insertion slot 221 to prevent the protective cover 22 from coming out of the base body 21 along the third direction. Then, the insertion hole 222 on the protective cover 22 is aligned with the insertion protrusion 214 on the base body 21, and the insertion protrusion 214 is pressed by hand until it is installed in place, and the protective cover 22 and the base body 21 will be firmly engaged.

[0058] It is worth noting that, regarding the output electrode base 2 mounting structure suitable for mounting the output electrode base 2 on the module end plate 1 in this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still based on... Figures 1 to 8 As shown, it includes an insertion part and a snap-fit ​​part disposed between the module end plate 1 and the output electrode base 2.

[0059] The insertion part can insert the output electrode base 2 and the module end plate 1 together in a first direction, and at least restrict the displacement of the output electrode base 2 in a second direction. As the output electrode base 2 and the module end plate 1 are inserted, the snap-fit ​​part can snap the output electrode base 2 and the module end plate 1 together, and restrict the displacement of the output electrode base 2 in the first direction. The insertion part includes a mounting groove 11 provided at one end of the module end plate 1, and an insertion block 211 provided on the output electrode base 2. The side wall of the mounting groove 11 is provided with a slot 11111 extending in the first direction, and the insertion block 211 is inserted into the slot 11111.

[0060] The module end plate 1 has two mounting blocks 1111 arranged opposite each other at one end. The mounting groove 11 is formed by the two mounting blocks 1111, and each mounting block 1111 has a slot 11111. The output electrode base 2 has two opposite ends with insertion blocks 211. The insertion block 211 includes a connecting arm 2111 cantilevered on the output electrode base 2 and a protrusion 2112 at the free end of the connecting arm 2111. The protrusion 2112 protrudes outward from the output electrode base 2 in a second direction and is inserted into the slot 11111. Each mounting block 1111 has a limiting block 11112, which is used to limit the insertion block 211 from dislodging from the slot 11111 in a first direction.

[0061] The snap-fit ​​portion includes a snap-fit ​​groove 12 located at the bottom of the mounting groove 11 and a snap-fit ​​block 212 located at the bottom of the output electrode base 2.
