Description

Technical Field

[0001] This application relates to the field of battery pack activation testing technology, and in particular to an activation testing fixture for battery packs. Background Technology

[0002] Once the battery pack is off the production line, its built-in MOSFET switch is usually disconnected to prevent accidental conduction during transportation or storage, ensuring that the battery pack remains powered off during transportation or storage.

[0003] During the vehicle assembly process, the battery pack needs to be connected to the vehicle's electrical system. However, since the MOSFET switches inside the battery pack are still in the off state, the communication port of the battery pack needs to be electrically connected to the terminal block to activate it before or during the connection process, thereby closing the MOSFET switches inside the battery pack.

[0004] In related technologies, assembly personnel currently rely mainly on listening to sounds or silently counting time to determine whether the battery pack has been successfully activated during the activation process. However, these methods have problems such as being unintuitive, susceptible to environmental interference, and having low reliability, which increases the risk of misjudging battery pack activation. Utility Model Content

[0005] This application provides an activation detection fixture for battery packs, which solves the problems of unintuitive judgment, susceptibility to environmental interference, and low reliability of judgment, and helps to reduce the risk of false judgment of battery pack activation.

[0008] The indicator light is mounted on the PCB board, the first connector is used for electrical connection with the communication port, and the second connector is used for electrical connection with the terminal block.

[0009] According to the embodiment of this application, the activation detection fixture for a battery pack has a first connector for electrical connection to a communication port and a second connector for electrical connection to a terminal block. This configuration enables pre-connection activation of the battery pack between the communication port and the terminal block. After the communication port and the terminal block are pre-connected, the indicator light status can provide assembly personnel with an intuitive and visual basis for judgment. For example, when the indicator light is on, it indicates successful activation, and when the indicator light is off, it indicates failed activation. This solves the problems of unintuitive judgment, susceptibility to environmental interference, and low reliability of judgment, and helps to reduce the risk of misjudgment of battery pack activation.

[0011] Optionally, the communication port has a first limiting part, and the first connector has a second limiting part that mates with the first limiting part;

[0012] Along the insertion direction of the first connector, the first connector is restricted from moving further by the limiting assembly between the first limiting part and the second limiting part, so that the first connector is limited to the insertion fixed position that is assembled with the communication port.

[0013] Optionally, one of the first limiting part and the second limiting part is configured as a limiting groove, and the other is configured as a limiting protrusion.

[0014] Optionally, the communication port has a first guide portion, and the first connector has a second guide portion that mates with the first guide portion. Through the guiding engagement of the first guide portion and the second guide portion, the first connector can be moved relative to the communication port along the insertion direction of the first connector.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0040] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0043] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0044] It should be noted that after the battery pack is produced, in order to prevent the battery pack from being accidentally turned on during transportation or storage, its built-in MOSFET switch is usually disconnected to ensure that the battery pack is always in a power-off state during transportation or storage.

[0045] During the vehicle assembly process, the battery pack needs to be connected to the vehicle's electrical system. However, since the MOSFET switches inside the battery pack are still in the off state, the communication port of the battery pack needs to be electrically connected to the terminal block to activate it before or during the connection process, thereby closing the MOSFET switches inside the battery pack.

[0046] In related technologies, assemblers currently rely mainly on the following two subjective judgment methods to confirm whether the battery pack has been successfully activated and powered.

[0047] The first method is by listening: When the MOSFET switch inside the battery pack is closed, it will produce a mechanical clicking sound. Assembly personnel need to listen to this sound to make a judgment.

[0048] However, this method has significant drawbacks. Environmental noise in the production site (such as equipment operation noise and personnel conversation noise) can easily mask or interfere with the identification of the closing sound, which makes it impossible for assembly personnel to accurately perceive the closed state of the MOSFET switch, thus causing misjudgment or omission of the battery pack's power-on status.

[0049] The second method is the silent timing method: This method sets the theoretical time from when the tooling contacts the battery pack to when the MOSFET switch closes to complete activation to approximately 5 seconds. The assembler must silently count the seconds; once the predetermined time is reached, activation is considered successful.

[0050] However, this method also has serious shortcomings. On the one hand, the actual activation time may deviate from the theoretical value due to fluctuations in factors such as contact resistance, battery status, or ambient temperature. On the other hand, assembly personnel are easily disturbed in noisy, high-pressure production environments, leading to counting errors.

[0051] In summary, both of the above methods suffer from problems such as lack of intuitiveness in judgment, susceptibility to environmental interference, and low reliability, which increase the risk of misjudgment of battery pack activation.

[0052] Based on this, this application proposes an activation detection fixture 100 for a battery pack 200. The first connector 1 of the activation detection fixture 100 is used to electrically connect to the communication port 210, and the second connector 4 is used to electrically connect to the terminal 220. This configuration enables the pre-connection activation of the battery pack 200 between the communication port 210 and the terminal 220. After the communication port 210 and the terminal 220 are pre-connected, the indicator light 3 can provide assembly personnel with an intuitive and visual judgment basis. For example, when the indicator light 3 is lit, it indicates that the activation is successful, and when the indicator light 3 is off, it indicates that the activation has failed. This solves the problems of unintuitive judgment, susceptibility to environmental interference, and low reliability of judgment, and helps to reduce the risk of misjudgment of the activation of the battery pack 200.

[0053] The activation detection fixture 100 for a battery pack 200 proposed in this application is described below with reference to the accompanying drawings.

[0054] like Figures 1-6 As shown, the activation detection fixture 100 according to the first aspect embodiment of this application includes: a first connector 1, a PCB board 2, an indicator light 3, and a second connector 4. The first connector 1, the PCB board 2, and the second connector 4 are connected in sequence. The indicator light 3 is disposed on the PCB board 2. The first connector 1 is used to electrically connect to the communication port 210 of the battery pack 200, and the second connector 4 is used to electrically connect to the terminal block 220 of the battery pack 200.

[0055] Specifically, such as Figures 4-6 As shown, the battery pack 200 includes a communication port 210 and a terminal 220. It should be noted that in some embodiments of this application, the communication port 210 and the terminal 220 of the battery pack 200 are pre-connected to transmit an activation signal in order to perform a specific activation operation of the battery pack 200. Optionally, the terminal 220 can be a negative terminal or a positive terminal, depending on the activation requirements of the battery pack 200.

[0056] For example, if the preset activation strategy inside the battery pack 200 is to pre-connect the communication port 210 to the negative terminal, then the activation detection fixture 100 will be used to pre-connect the communication port 210 of the battery pack 200 to the negative terminal. Alternatively, if the preset activation strategy inside the battery pack 200 is to pre-connect the communication port 210 to the positive terminal, then the activation detection fixture 100 will be used to pre-connect the communication port 210 of the battery pack 200 to the positive terminal.

[0057] Please refer to Figure 1 , Figures 4-6As shown, the activation detection fixture 100 has a first connector 1 and a second connector 4 at both ends. The first connector 1, the PCB board 2, and the second connector 4 are connected in sequence. This application takes the pre-connection activation of the communication port 210 and the negative terminal of the battery pack 200 as an example. When the first connector 1 is electrically connected to the communication port 210 of the battery pack 200 and the second connector 4 is electrically connected to the terminal 220 of the battery pack 200, the activation detection fixture 100 acts as the activation signal transmission line between the communication port 210 and the negative terminal, and the battery pack 200 is activated according to the internal preset activation strategy.

[0058] Since there is an indicator light 3 on the PCB board 2, if the battery pack 200 is successfully activated, the MOSFET switch inside the battery pack 200 will be closed and the battery pack 200 will be powered normally. In this way, the battery pack 200 can supply power to the indicator light 3 on the PCB board 2 and the indicator light 3 will light up. If the battery pack 200 fails to activate, the MOSFET switch inside the battery pack 200 will remain in the open state. Therefore, the battery pack 200 cannot supply power to the indicator light 3 on the PCB board 2 and the indicator light 3 will turn off.

[0059] With this configuration, when assembly personnel use the activation detection fixture 100 in this application to determine the activation status of the battery pack 200, the light status of the indicator light 3 on the activation detection fixture 100 can provide assembly personnel with an intuitive and visual basis for judgment. This not only avoids interference from the external environment, but also ensures high reliability of the judgment, greatly reducing the risk of misjudging the activation of the battery pack 200. At the same time, it can also reduce the rework rate caused by misjudgment, ensuring the normal operation of the battery pack 200 and the reliability of the overall vehicle quality.

[0060] In summary, the activation detection fixture 100 for the battery pack 200 proposed in this application embodiment has a first connector 1 for electrical connection with the communication port 210 and a second connector 4 for electrical connection with the terminal block 220. This configuration enables the pre-connection activation of the battery pack 200 between the communication port 210 and the terminal block 220. After the communication port 210 and the terminal block 220 are pre-connected, the indicator light 3 can provide assembly personnel with an intuitive and visual basis for judgment. For example, when the indicator light 3 is lit, it indicates successful activation, and when the indicator light 3 is off, it indicates failed activation. This solves the problems of unintuitive judgment, susceptibility to environmental interference, and low reliability of judgment, and helps to reduce the risk of misjudgment of battery pack 200 activation.

[0061] In some embodiments of this application, the first connector 1 is plugged into the communication port 210.

[0062] In other words, both the first connector 1 and the communication port 210 of the battery pack 200 are configured as plug-in structures. For example, the first connector 1 can be configured as a male plug and the communication port 210 can be configured as a female plug. The male plug can be any one of USB male plug, RJ45 plug, USB-C male plug, M12 connector, or D-Sub (DB9 / DB25) plug. The female plug can be a USB-A female plug, RJ45 port, USB-C female plug, M12 port, or D-Sub port. For example, if the first connector 1 is an RJ45 plug, then the communication port 210 is an RJ45 port.

[0063] With this configuration, the first connector 1 and the communication port 210 can be quickly connected and disconnected through the plug-in assembly. After the current battery pack 200 is activated and tested, the first connector 1 can be quickly disconnected from the current battery pack 200 and inserted into the next battery pack 200 to be tested, thus improving the activation and testing efficiency of the battery pack 200.

[0064] In some embodiments of this application, such as Figure 2 and Figure 6 As shown, the communication port 210 has a first limiting part 211, and the first connector 1 has a second limiting part 11 that is fitted with the first limiting part 211. Along the insertion direction X of the first connector 1, the first connector 1 is restricted from continuing to move by the limiting assembly between the first limiting part 211 and the second limiting part 11, so that the first connector 1 is limited to the insertion fixed position fitted with the communication port 210.

[0065] Specifically, such as Figure 6 As shown, the communication port 210 has a first limiting part 211, such as Figure 2 As shown, the first connector 1 has a second limiting part 11 that is fitted to the first limiting part 211. When the first connector 1 is inserted into the communication port 210, the first connector 1 can move to the insertion fixed position that is fitted to the communication port 210. When the first connector 1 is in the insertion fixed position, the first limiting part 211 and the second limiting part 11 abut against each other along the insertion direction X of the first connector 1. Thus, the first limiting part 211 can restrict the second limiting part 11 from continuing to move, thereby restricting the first connector 1 in the insertion fixed position from continuing to move along the insertion direction X of the first connector 1.

[0066] This design serves two purposes: firstly, it alerts the assembly personnel that the first connector 1 has been properly inserted, ensuring the stability of signal transmission; secondly, when the first connector 1 is disassembled in the direction opposite to the insertion direction X, the first limiting part 211 does not restrict the movement of the first connector 1, facilitating the disassembly and replacement of the first connector 1.

[0067] In some embodiments of this application, one of the first limiting part 211 and the second limiting part 11 is configured as a limiting groove, and the other is configured as a limiting protrusion.

[0068] In other words, when the first limiting part 211 is constructed as a limiting groove, the second limiting part 11 is constructed as a limiting protrusion; when the first limiting part 211 is constructed as a limiting protrusion, the second limiting part 11 is constructed as a limiting groove. As a specific example, refer to... Figure 2 and Figure 6 As shown, the first limiting part 211 is a limiting protrusion, and the second limiting part 11 is a limiting groove.

[0069] This configuration, through the limiting cooperation between the limiting groove and the limiting protrusion, not only achieves the insertion limit between the first connector 1 and the communication port 210, but also simplifies the limiting structure, making the processing simpler and the cost lower.

[0070] In some embodiments of this application, such as Figure 2 and Figure 6 As shown, the communication port 210 has a first guide portion 212, and the first connector 1 has a second guide portion 12 that is fitted with the first guide portion 212. Through the guiding fit between the first guide portion 212 and the second guide portion 12, the first connector 1 can be moved relative to the communication port 210 along the insertion direction X of the first connector 1.

[0071] Specifically, such as Figure 6 As shown, the communication port 210 has a first guide portion 212, such as Figure 2 As shown, the first connector 1 has a second guide portion 12 that mates with the first guide portion 212. It can be understood that both the first guide portion 212 and the second guide portion 12 extend along the insertion direction X of the first connector 1. When the first connector 1 is inserted into the communication port 210, the first connector 1 moves relative to the communication port 210 along the insertion direction X of the first connector 1. The first guide portion 212 can guide the second guide portion 12. This arrangement can prevent the first connector 1 from shifting when it moves along the insertion direction X of the first connector 1, thus ensuring the stability of the movement of the first connector 1 during installation.

[0072] It should be noted that when the first connector 1 is disassembled in a direction opposite to the insertion direction X of the first connector 1, the first guide part 212 can also guide the second guide part 12, further ensuring the stability of the movement of the first connector 1 during disassembly.

[0073] In some embodiments of this application, one of the first guide portion 212 and the second guide portion 12 is configured as a guide rail, and the other is configured as a guide groove.

[0074] In other words, when the first guide portion 212 is configured as a guide rail, the second guide portion 12 is configured as a guide groove; when the first guide portion 212 is configured as a guide groove, the second guide portion 12 is configured as a guide rail. As a specific example, refer to... Figure 2 and Figure 6 As shown, the first limiting part 211 is a guide rail, and the second limiting part 11 is a guide groove. This arrangement, through the guiding cooperation between the guide rail and the guide groove, not only ensures the stability of the first connecting member 1 during movement, but also simplifies the guiding structure, making processing simpler and less expensive.

[0075] In some embodiments of this application, the second connector 4 is snapped onto the terminal 220. Specifically, the second connector 4 may be provided with a resilient buckle, resilient clip, or other structure. Through the snap-fit ​​assembly between the second connector 4 and the terminal 220, the second connector 4 and the terminal 220 can be quickly installed or removed, which is beneficial to further improve the activation detection efficiency of the battery pack 200.

[0076] In some embodiments of this application, such as Figures 3-5 As shown, the second connector 4 has a snap-fit ​​portion 41, which is constructed as a semi-cylindrical groove that matches the outer peripheral surface of the terminal 220.

[0077] Specifically, such as Figure 5 As shown, the terminal 220 is cylindrical, and the snap-fit ​​part 41 of the second connector 4 is a semi-cylindrical groove. The diameter of the semi-cylindrical groove is equal to or slightly smaller than the diameter of the terminal 220. When the second connector 4 and the terminal 220 are assembled, the semi-cylindrical groove is directly snapped onto the outer circumference of the terminal 220. This arrangement utilizes the elastic force formed by the semi-cylindrical groove and the terminal 220 to achieve relative fixation between them. At the same time, the semi-cylindrical groove can also position the terminal 220 along its axial direction. When it is necessary to disassemble and activate the testing fixture 100, the second connector 4 can be directly pulled off the terminal 220. Installation and disassembly are both convenient. Moreover, the semi-cylindrical groove is designed to fit the terminal 220, eliminating the need for a fixing structure on the terminal 220. This reduces the number of parts. In addition, the semi-cylindrical groove is easy to manufacture and has a lower cost.

[0078] In some embodiments of this application, the indicator light 3 is constructed as a surface-mount LED indicator light. Specifically, the surface-mount LED indicator light can be directly soldered onto the PCB board 2, making the installation simple and reliable. The core advantages of the surface-mount LED indicator light are its small size and low height, which significantly saves space on the PCB board 2, contributing to the miniaturization and thinning of the device. The surface-mount LED indicator light has excellent heat dissipation performance and mechanical stability, with better heat conduction through large-area solder pads, stronger resistance to vibration and shock, and improved reliability and lifespan. The surface-mount LED indicator light has high design flexibility, can be freely arranged on the board surface, and has a simple and beautiful appearance. At the same time, the surface-mount LED indicator light has lower parasitic inductance and overall cost advantages, making it the preferred solution for indicator lights 3 in modern electronic devices.

[0079] In some embodiments of this application, a flexible wire harness 5 is also included, wherein the first connector 1, the PCB board 2, and the second connector 4 are connected sequentially via the flexible wire harness 5.

[0080] Specifically, the flexible wire harness 5 can be bent. The first connector 1, PCB board 2, and second connector 4 are connected sequentially through the flexible wire harness 5, which can maximize the flexibility of the activation detection fixture 100. For example, when the activation detection fixture 100 is installed with the battery pack 200, the bending angle of the flexible wire harness 5 can be adjusted as needed, so that the first connector 1 and the communication port 210 and the second connector 4 and the terminal 220 can maintain reliable electrical contact, thereby improving the reliability of the activation judgment of the activation detection fixture 100 and further reducing the risk of false activation judgment of the battery pack 200.

[0081] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0082] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
