Description

Technical Field

[0001] This application relates to the field of battery pack technology, and in particular to an output terminal base and a battery pack. Background Technology

[0002] The battery cells inside the battery pack conduct electrical energy to the vehicle's motor or other electrical equipment through the output terminals, thereby enabling the battery pack to supply energy to the vehicle. Since the output terminals are usually made of copper, a material with high electrical conductivity, they are relatively soft and easily twist and deform with the bumps and swaying of the vehicle. Therefore, an output terminal base is required to fix the output terminals in place.

[0003] However, the output terminal base is usually an injection molded part. Due to the different heights of different cells or spatial arrangement issues, different battery packs need to be matched with different output terminal bases, which is not conducive to improving the versatility of the output terminal base. Utility Model Content

[0004] In view of this, this application aims to provide an output electrode base to improve the versatility of the output electrode base.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] An output electrode base for fixing the electrodes of a battery pack includes a base body with inserts and a mounting portion detachably connected to the base body.

[0007] The insert is used to fix the output terminal of the battery pack;

[0008] The base body is detachably mounted on the mounting base of the battery pack via the mounting part.

[0009] Furthermore, the base body is provided with a first through hole, and the mounting part is provided with a first claw;

[0010] The free end of the first claw can pass through the first through hole and hook onto the base body, enabling the mounting part to be snapped into contact with the base body.

[0011] Furthermore, the mounting part includes a first mounting body with the first claw, and a second mounting body detachably connected to the first mounting body, wherein the mounting part is detachably connected to the mounting base through the second mounting body.

[0012] Furthermore, the first mounting body is provided with a second through hole, and the second mounting body has a second claw. The free end of the second claw can pass through the second through hole and hook onto the first mounting body, so that the second mounting body can be snapped together with the first mounting body.

[0013] Furthermore, the base body is provided with a third through hole, and the free end of the second claw can pass through the third through hole and hook onto the base body, so that the second mounting body can be snapped and connected to the base body.

[0014] Furthermore, the first claw is provided with at least one pair, and the hooking directions of the first claws in the same pair are opposite.

[0015] Furthermore, the second claw is provided with at least one pair, and the hooking directions of the second claws in the same pair are opposite.

[0016] Furthermore, the mounting part is plugged into and connected to the mounting base.

[0017] Furthermore, the insert includes a nut insert fitted onto the base body;

[0018] The nut insert is connected to an external fastener, which can press the output electrode onto the nut insert.

[0019] Furthermore, a limiting groove is provided on one side of the base body. The limiting groove is recessed into the base body itself and extends in a preset direction, so that the output electrode can pass through the limiting groove in the preset direction.

[0020] Compared with related technologies, this application has the following advantages:

[0021] (1) The output electrode base described in this application is provided with a detachable mounting part, thereby allowing the base body and the mounting part to be modularly designed separately. Under the premise that the base body can fix the output electrode, different mounting parts and mounting bases can be connected to realize the adaptation of the output electrode base to battery packs with different output electrode positions, enriching the usage scenarios of the output electrode base and improving the versatility of the output electrode base.

[0022] (2) By setting a first through hole on the base body and a first clip on the mounting part, the base body and the mounting part can be snapped together without the need for additional tools. The connection operation is convenient, and the snapping is more secure and reliable because the first clip passes through the first through hole.

[0023] (3) Setting the mounting part to be connected to the first mounting body and the second mounting body can further improve the modular and platform design of the output pole base, making the structure of the mounting part more flexible. In the actual production and assembly process, the first mounting body and the second mounting body can be designed and adjusted according to different usage requirements and the characteristics of the mounting base. When the connection form between the second mounting body and the mounting base is determined, the position of the base body can be adjusted by replacing the first mounting body when the output pole base is used in the position of the output pole of different battery packs.

[0024] (4) By setting a second through hole on the first mounting body and a second claw on the second mounting body, the first mounting body and the second mounting body can be connected without the need for additional tools. The connection operation is convenient, and the second claw passes through the second through hole to make the connection more secure and reliable.

[0025] (5) By opening a third through hole on the base body, the second mounting body can be directly connected to the base body, eliminating the need for the first mounting body between the base body and the second mounting body, adapting to the battery pack at the corresponding output pole position, and further improving the versatility of the output pole base.

[0026] (6) Set at least one pair of first claws and set the first claws of the same pair to hook in opposite directions. This can not only improve the locking strength of the first claws, but also facilitate the disassembly of the first mounting body; set at least one pair of second claws and set the second claws of the same pair to hook in opposite directions. This can not only improve the locking strength of the second claws, but also facilitate the disassembly of the second mounting body.

[0027] (7) The mounting part is plugged into the mounting base. The plug-in method is characterized by quick installation and accurate positioning. During the installation process, the mounting part can be quickly and accurately connected to the mounting base, which improves the assembly efficiency. In addition, the plug-in connection also facilitates the disassembly of the output pole base, which is beneficial for subsequent maintenance and replacement operations.

[0028] (8) The nut insert can firmly connect the base body and withstand a large tightening force to provide a stable screw base for external fasteners, prevent the output pole from loosening or shifting during use, and ensure the stability of the battery pack electrode connection.

[0029] (9) The limiting groove provides installation guidance and positioning for the output electrode, enabling the output electrode to be accurately installed in the predetermined position, ensuring the consistency and accuracy of electrode installation; at the same time, the limiting groove plays a certain limiting and protection role for the output electrode, reducing the offset or shaking of the output electrode during installation or use, which is conducive to improving the stability and reliability of the fit between the output electrode base and the output electrode.

[0030] This application also proposes a battery pack having the aforementioned output terminal base.

[0031] The battery pack described in this application, by setting the aforementioned output pole base, has a detachable mounting part, which enables the modular design of the base body and the mounting part. The same base body can be connected to multiple mounting parts of different specifications. Under the premise that the base body can fix the output pole, the output pole base can be adapted to the output pole at different positions. This is conducive to the platform design of the components in the battery pack, improves the utilization rate of components, and reduces design and development costs. Attached Figure Description

[0048] 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. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0050] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. 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.

[0052] 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.

[0053] 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.

[0054] An embodiment of the first aspect of this application provides an output electrode base.

[0055] In related technologies, the battery cells inside the battery pack conduct energy to the vehicle's motor or other electrical equipment through the output electrode, thereby enabling the battery pack to supply energy to the vehicle. Since the output electrode is usually made of copper, a material with high conductivity, it is relatively soft and easily twists and deforms with the bumps and swaying of the vehicle. Therefore, an output electrode base is needed to fix the output electrode in place.

[0056] However, the output terminal base is usually an injection molded part. Due to the different heights of different cells or spatial arrangement issues, different battery packs need to be matched with different output terminal bases, resulting in poor versatility of the output terminal base.

[0057] In view of this, and to overcome the shortcomings of related technologies, in the output electrode base for fixing the battery pack electrodes in this embodiment, a combination is made... Figures 1 to 4 In terms of content and overall design, it includes a base body 1 with inserts and a mounting part 2 that is detachably connected to the base body 1.

[0058] The insert is used to fix the output terminal 3 of the battery pack. The base body 1 is detachably mounted on the mounting base of the battery pack via the mounting part 2.

[0059] Therefore, the output electrode base of this embodiment, by providing a detachable mounting part 2, allows for modular design of the base body 1 and the mounting part 2 respectively. Under the premise that the base body 1 can fix the output electrode 3, different mounting parts 2 can be connected with the mounting base to realize the adaptation of the output electrode base to battery packs at different output electrode 3 positions, enriching the usage scenarios of the output electrode base and improving the versatility of the output electrode base.

[0060] Based on the above overview, specifically, the electrodes of the battery pack refer to the conductor connection terminals that electrically connect the battery pack to external devices. These include the output electrode 3 and the connecting piece 6. The output electrode 3 is used for wiring the battery pack to external equipment or systems, while the connecting piece 6 is used to connect the copper busbars that conduct current within the battery pack. The insert provides a base for fixing the output electrode 3 and the connecting piece 6, facilitating secure mounting. The mounting base within the battery pack can be the battery pack housing 4, the end plate, or other internal components that provide mounting points.

[0061] Continue to combine Figures 1 to 4 In some exemplary embodiments shown, the base body 1 has a first through hole 102, and the mounting part 2 has a first latch 201. The free end of the first latch 201 can pass through the first through hole 102 and hook onto the base body 1, enabling the mounting part 2 to be snapped into place with the base body 1. By providing the first through hole 102 on the base body 1 and the first latch 201 on the mounting part 2, the base body 1 and the mounting part 2 can be snapped together without the need for additional tools, making the connection operation convenient. Furthermore, the snapping method of the first latch 201 passing through the first through hole 102 ensures a relatively firm and reliable connection.

[0062] It is understandable that the detachable connection between the mounting part 2 and the base body 1 can be achieved through screwing, bolting, or plugging. When bolting is used, a bolt can be threaded through the mounting part 2 and screwed onto the base body 1, with the bolt nut pressing the mounting part 2 firmly onto the base body 1. When plugging is used, a socket can be provided on the mounting part 2, and a plug can be provided on the base body 1. The output electrode base is installed through an interference fit between the plug and the socket.

[0063] Based on the first through hole 102 on the base body 1 and the first claw 201 on the mounting part 2, referring to Figure 2 and Figure 3 As shown, in some exemplary embodiments, the mounting part 2 includes a first mounting body 202 with a first claw 201 and a second mounting body 203 detachably connected to the first mounting body 202. The mounting part 2 is detachably connected to the mounting base through the second mounting body 203.

[0064] This configuration, where the first mounting body 202 and the second mounting body 203 are detachably connected, further enhances the modular and platform-based design of the output electrode base, making the structure of the mounting part 2 more flexible. During actual production and assembly, the first mounting body 202 and the second mounting body 203 can be designed and adjusted according to different usage requirements and the characteristics of the mounting base. When the connection method between the second mounting body 203 and the mounting base is determined, and the output electrode base is used at different battery pack output electrode 3 positions, the position of the base body 1 can be adjusted by replacing the suitable first mounting body 202.

[0065] Reference Figure 2 and Figure 4 Based on the content described above, the mounting part 2 includes a first mounting body 202 and a second mounting body 203. In some exemplary embodiments, the first mounting body 202 has a second through hole 2021, and the second mounting body 203 has a second claw 204. The free end of the second claw 204 can pass through the second through hole 2021 and hook onto the first mounting body 202, enabling the second mounting body 203 to be snapped into place with the first mounting body 202. By providing the second through hole 2021 on the first mounting body 202 and the second claw 204 on the second mounting body 203, the snapping of the first mounting body 202 and the second mounting body 203 can be achieved without the need for additional tools, making the connection operation convenient. Furthermore, the snapping method of the second claw 204 passing through the second through hole 2021 ensures a more secure and reliable connection.

[0066] It should be noted that the detachable connection between the first mounting body 202 and the second mounting body 203 can also be in the form of screw connection, bolt connection, or plug connection. When using a bolt connection, a bolt can be passed through the second mounting body 203 and screwed to the first mounting body 202, with a nut pressing the second mounting body 203 tightly onto the base body 1. When using a plug connection, a socket can be provided on the second mounting body 203, and a plug can be provided on the first mounting body 202. The assembly of the mounting part 2 is achieved through the interference fit between the plug and the socket.

[0067] See Figure 2 , Figure 4 and Figure 5 Based on the premise that the second mounting body 203 is provided with a second claw 204, in some exemplary embodiments, the base body 1 is provided with a third through hole 103. The free end of the second claw 204 can pass through the third through hole 103 and hook onto the base body 1, enabling the second mounting body 203 to be snapped into place with the base body 1. By providing a third through hole 103 on the base body 1, the second mounting body 203 can be directly snapped into place with the base body 1, eliminating the need for a first mounting body 202 between the base body 1 and the second mounting body 203. This adapts to battery packs at the corresponding output pole 3 position, further improving the versatility of the output pole base.

[0068] It is worth noting that when the second mounting body 203 is snapped into connection with the base, the mounting part 2 can also be understood as including only the second mounting body 203. At this time, the mounting part 2 uses the second claw 204 to connect with the base body 1 through the third through hole 103. This is equivalent to the aforementioned mounting part 2 using the first claw 201 to connect with the base body 1 through the first through hole 102. The two forms achieve basically the same effect.

[0069] Still refer to Figure 2 , Figure 4 and Figure 5 Based on the premise that the first mounting body 202 has a first claw 201 and the second mounting body 203 has a second claw 204, in some exemplary embodiments, the first claw 201 is provided in at least one pair, and the hooking directions of the first claw 201 in the same pair are opposite. Providing at least one pair of first claws 201, and setting the hooking directions of the first claws 201 in the same pair in opposite directions, not only improves the locking strength of the first claws 201, but also facilitates the disassembly of the first mounting body 202.

[0070] Preferably, two pairs of first claws 201 are provided, respectively arranged on both sides of the first mounting body 202. The free ends of the same pair of first claws 201 extend in opposite directions, specifically in the form of triangular claw heads, which facilitates the insertion of the first claws 201 into the first through hole 102.

[0071] Accordingly, in some exemplary embodiments, the second claw 204 is provided in at least one pair, with the hooking directions of the same pair of second claws 204 being opposite. Providing at least one pair of second claws 204 and setting the hooking directions of the same pair of second claws 204 in opposite ways can not only improve the locking firmness of the second claws 204, but also facilitate the disassembly of the second mounting body 203.

[0072] Preferably, two pairs of second claws 204 are provided, respectively arranged on both sides of the second mounting body 203. The free ends of the same pair of second claws 204 extend in opposite directions, specifically in the form of triangular claw heads, which facilitates the insertion of the second claws 204 into the second through hole 2021 or the third through hole 103. The first mounting body 202 is provided with a receiving groove 2022, and the second through hole 2021 is located at the bottom of the receiving groove 2022. The second claws 204 pass through the opening of the second through hole 2021 and hook onto the bottom of the receiving groove 2022, so that the second claws 204 do not protrude from the surface of the first mounting body 202.

[0073] Continue to refer to Figure 2 and Figure 3 In some exemplary embodiments, the mounting part 2 is plugged into the mounting base. The plug-in connection method features rapid installation and accurate positioning. During installation, the mounting part 2 can be quickly and accurately aligned with the mounting base, improving assembly efficiency. Furthermore, the plug-in connection facilitates the disassembly of the output electrode base, which is beneficial for subsequent maintenance and replacement operations.

[0074] For example, a plug-in end 2031 may be provided on the side of the second mounting body 203 facing away from the second claw 204. The plug-in end 2031 adopts a rectangular cross-section column shape and has a chamfer at the end head to facilitate insertion.

[0075] Based on the condition that the mounting part 2 is inserted into the mounting base, combined with Figure 2 and Figure 3 In some exemplary embodiments, the insert includes a nut insert 101 fitted onto the base body 1. The nut insert 101 connects to the external fastener 5, pressing the output electrode 3 against the nut insert 101. The nut insert 101 securely connects to the base body 1 and can withstand significant tightening forces, providing a stable screw base for the external fastener 5, preventing loosening or displacement of the output electrode 3 during use, and ensuring the stability of the battery pack electrode connection.

[0076] Specifically, the base body 1 can be manufactured using injection molding. During the molding process, a nut insert 101 is pre-installed, so that the base body 1 is fixedly connected to the nut insert 101 after molding, resulting in good bonding strength. The fastener 5 can be a bolt. Specifically, through mounting holes can be made on the output pole 3 and the connecting piece 6. After the bolt passes through the mounting holes of the output pole 3 and the connecting piece 6, it is tightened onto the nut insert 101. The bolt nut can simultaneously press and fix the output pole 3 and the connecting piece 6 onto the nut insert 101.

[0077] Based on the use of nut insert 101 as an insert, referring to Figure 1 and Figure 2 As shown, in some exemplary embodiments, a limiting groove 104 is provided on one side of the base body 1. The limiting groove 104 is recessed into the base body 1 and extends in a preset direction, allowing the output electrode 3 to pass through the limiting groove 104 in the preset direction. The limiting groove 104 provides installation guidance and positioning for the output electrode 3, enabling the output electrode 3 to be accurately installed in the predetermined position, ensuring the consistency and accuracy of electrode installation. At the same time, the limiting groove 104 plays a certain limiting and protection role for the output electrode 3, reducing the displacement or shaking of the output electrode 3 during installation or use, which is beneficial to improving the stability and reliability of the fit between the output electrode base and the output electrode 3. The preset direction is the direction in which the output electrode 3 needs to be led out of the battery pack.

[0078] For example, the base body 1 can be set as a cuboid with an open top, and a limiting groove 104 can be provided on one side wall of the base body 1 so that the output electrode 3 can pass through the limiting groove 104. The base body 1 is provided with a limiting groove 104 on the corresponding side wall, and a through groove 105 is provided on the other side wall. The connecting piece 6 enters the base body 1 through the through groove 105 and connects with the output electrode 3.

[0079] At the same time, a weight-reducing groove 106 can be provided at the bottom of the base body 1. The first through hole 102 and the second through hole 2021 are both located at the bottom of the weight-reducing groove 106, so that the weight-reducing groove 106 can not only reduce the weight of the base body 1, but also shorten the length required for the first claw 201 and the second claw 204.

[0080] It is worth noting that, regarding the output terminal base of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still [constructed by...]. Figures 1 to 4 As shown, it may include, for example, a base body 1 with a nut insert 101 and a mounting portion 2 with a first through hole 102.

[0081] The mounting part 2 includes a first mounting body 202 and a second mounting body 203. The first mounting body 202 is provided with a first claw 201 and a second through hole 2021. The first mounting body 202 is hooked onto the mounting part 2 by the first claw 201 passing through the first through hole 102. The second mounting body 203 is provided with a second claw 204. The second mounting body 203 is hooked onto the first mounting body 202 by the second claw 204 passing through the second through hole 2021, so that the base body 1, the first mounting body 202 and the second mounting body 203 are sequentially hooked and connected in the vertical direction.

[0082] The first claw 201 has two pairs, with the first claw 201 of the same pair hooking in opposite directions. The second claw 204 has two pairs, with the second claw 204 of the same pair hooking in opposite directions.

[0083] The second mounting body 203 is provided with a plug-in end 2031, which is vertically inserted into the battery pack housing 4.

[0084] The insert is a nut insert 101, which is screwed to the bolt so that the nut of the bolt presses the output pole 3 and the connecting piece 6 onto the nut insert 101.

[0085] In the above preferred embodiments, the specific configuration and arrangement of the base body 1 and the mounting part 2 can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the base body 1 and the mounting part 2 can also be referred to the descriptions in the above exemplary embodiments.

[0086] The output electrode base of this embodiment adopts the above design. By setting a detachable mounting part 2, the base body 1 and the mounting part 2 can be modularly designed. Under the premise that the base body 1 can fix the output electrode 3, different mounting parts 2 can be connected with the mounting base to realize the adaptation of the output electrode base to battery packs at different output electrode 3 positions, which enriches the usage scenarios of the output electrode base and helps to improve the versatility of the output electrode base.

[0087] An embodiment of the second aspect of this application provides a battery pack having an output terminal base as described in the first aspect of this application.

[0088] Among them, reference Figure 3 As shown, the mounting part 2 is inserted into the battery pack housing 4, the output pole 3 and the connecting piece 6 are stacked in sequence, the fastener 5 is a bolt, which passes through the connecting piece 6 and the output pole 3 from top to bottom and is screwed into the nut insert 101, and presses the connecting piece 6 and the output pole 3. A protective cover 7 is snapped onto the base body 1. The protective cover 7 is used to protect the mounting points of the bolt, the output pole 3, the connecting piece 6 and the nut insert 101.

[0089] The battery pack described in this application, by setting the above-mentioned output pole base, has a detachable mounting part 2, which enables the modular design of the base body 1 and the mounting part 2. The same base body 1 can be connected to multiple mounting parts 2 of different specifications. Under the premise that the base body 1 can fix the output pole 3, the output pole base can be adapted to the output pole 3 at different positions, which is conducive to the platform design of the components in the battery pack, improves the utilization rate of components, and reduces design and development costs.
