Description

Technical Field

[0001] This application belongs to the field of battery technology, specifically relating to a battery module and electronic device. Background Technology

[0002] In related technologies, the main body of an electronic device is electrically connected to the connector of a battery module via a connection terminal, thereby achieving an electrical connection between the main body of the device and the battery module.

[0003] In related technologies, the battery cover is connected to the frame of the battery module and covers the circuit board of the battery module to protect and fix the circuit board. However, since the battery cover covers at least part of the connector and connection terminal, the operator can only judge whether the connector and connection terminal are properly mated by personal feeling, which can easily lead to mismatch between the connector and connection terminal and poor connection between the battery module and the main body of the equipment. Utility Model Content

[0004] The purpose of this application is to provide a battery module and electronic device that can solve the problem in the related art where connectors and connection terminals are easily mismatched, resulting in poor connection between the battery module and the device body.

[0005] In a first aspect, embodiments of this application provide a battery module, the battery module comprising:

[0006] A battery cover, wherein an observation window is provided on the battery cover, the observation window penetrating the battery cover along the thickness direction of the battery cover;

[0007] A circuit board, on which connectors are provided;

[0008] A connection terminal, wherein the connection terminal is used for electrical connection with the main body of the electronic device, and the connection terminal is electrically connected to the connector;

[0009] The observation window is positioned opposite to the connection point of the connector and the connection terminal.

[0010] Secondly, this application also provides an electronic device, which includes a device body, a connecting line, and the aforementioned battery module. The device body is electrically connected to the connecting terminal of the battery module via the connecting line.

[0011] In this embodiment, since the observation window is positioned opposite to the connection points of the connector and the connection terminals on the circuit board, when the connection terminals and the connector are mated together, the user can observe the degree of mating between the connection terminals and the connector through the observation window. This allows for precise adjustment of the connection degree between the connection terminals and the connector, effectively improving the mating accuracy between the connection terminals and the connector. This helps prevent poor connection between the connection terminals and the connector, thereby ensuring the performance of the electronic device. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The battery module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0030] refer to Figures 1-11 This application provides a battery module that may include a battery cover 400, a circuit board 300, and a connection terminal 500. The battery cover 400 can cover the circuit board 300 to protect and fix the circuit board 300. A connector 310 is provided on the circuit board 300, and the connection terminal 500 is used for electrical connection with the main body of an electronic device. The connection terminal 500 is electrically connected to the connector 310, thus realizing the electrical connection between the battery module and the main body of the device.

[0031] Among them, such as Figure 2 and Figure 3 As shown, an observation window 410 is provided on the battery cover 400. The observation window 410 can penetrate the battery cover 400 along the thickness direction of the battery cover 400. The observation window 410 is positioned opposite to the connection point of the connector 310 and the connection terminal 500 of the circuit board 300.

[0032] In this embodiment, since the observation window 410 is positioned opposite to the connection points of the connector 310 and the connection terminal 500 of the circuit board 300, when the connection terminal 500 and the connector 310 are mated together, the user can observe the degree of mating between the connection terminal 500 and the connector 310 through the observation window 410. This allows for precise adjustment of the connection degree between the connection terminal 500 and the connector 310, effectively improving the mating accuracy between the connection terminal 500 and the connector 310. This helps prevent poor connection between the connection terminal 500 and the connector 310, thereby ensuring the performance of the electronic device.

[0033] In one alternative embodiment of this application, such as Figure 3 As shown, the battery cover 400 has a first edge 401, and an observation window 410 is disposed on the battery cover 400 near the first edge 401. In this embodiment, the observation window 410 does not penetrate the first edge 401, making the structure of the battery cover 400 near the connector 310 more continuous and complete. This helps to enhance the overall structural strength of the battery cover 400, enabling it to better withstand external pressure and impact, thereby providing more reliable protection for the connector 310. At the same time, the size of the observation window 410 can be reduced, making the channel between the battery cover 400 and the connector 310 smaller, reducing the possibility of dust or debris entering the battery module.

[0034] In another optional embodiment of this application, the observation window 410 may extend through the first edge 401 of the battery cover 400 along the insertion direction of the connection terminal 500 and the connector 310. This arrangement, on the one hand, expands the observation range, which helps to monitor the connection status of the connector 310 and the connection terminal 500 more comprehensively and accurately; on the other hand, it facilitates the processing of the observation window 410 and helps to reduce the processing difficulty.

[0035] It should be noted that the first edge 401 of the battery cover 400 can be the edge of the slot 3111 of the connector 310 near the battery cover 400.

[0036] In an optional embodiment of this application, the battery module may further include a cover plate, which can be connected to the battery cover plate 400. The cover plate can cover the observation window 410, and the cover plate can be a transparent structure. In this embodiment, the cover plate effectively prevents dust or impurities from entering the battery module through the observation window 410, reducing the possibility of internal component failure due to dust or impurity accumulation, and helping to extend the battery module's lifespan. Furthermore, the transparent structure of the cover plate does not affect the observation of the connection status of the connector 310 and the connection terminal 500 through the observation window 410, while also providing a covering function.

[0037] Of course, in other embodiments, the battery module may not include a cover plate.

[0038] In an optional embodiment, the side of the cover plate near the connector 310 may be provided with an anti-fog coating. Since the battery module may generate heat and humidity changes during operation, the anti-fog coating in this embodiment can effectively prevent moisture from condensing into droplets on the cover plate, avoiding blurred vision and allowing the operator to always clearly observe the connection status between the connector 310 and the connection terminal 500 through the observation window 410. Optionally, the anti-fog coating can be made of nanocomposite materials or fluorocarbon resin materials; nanocomposite materials may include nano-titanium dioxide, nano-zinc oxide, etc.

[0039] Of course, the side of the cover plate closest to connector 310 may not have an anti-fog coating.

[0040] In an optional embodiment of this application, the cover plate can be detachably connected to the battery cover plate 400. In this embodiment, when it is necessary to observe the connection between the connector 310 and the connection terminal 500, the cover plate can be removed to facilitate observation by the operator. After the observation is completed, the cover plate can be installed to close the observation window 410, thereby preventing external dust or impurities from entering the interior of the battery module through the observation window 410.

[0041] Of course, in other embodiments, the cover plate may also be non-detachably connected to the battery cover plate 400.

[0042] Alternatively, the cover plate can be slidably or rotatably connected to the battery cover plate 400. When it is necessary to observe the connection between the connector 310 and the connection terminal 500, the cover plate can be slid or rotated to expose the observation window 410.

[0043] In an optional embodiment, the cover can be switched between a first position and a second position.

[0044] When the cover is in the first position, the cover covers the observation window 410. This setting can effectively prevent dust or impurities from entering the battery module through the observation window 410, reducing the possibility of internal components of the battery module malfunctioning due to the accumulation of dust or impurities, and helping to extend the service life of the battery module.

[0045] With the cover plate in the second position, the cover plate avoids the observation window 410, allowing the observation window 410 to be exposed. In this embodiment, the operator can switch the cover plate to the second position at any time as needed, exposing the observation window 410 to observe the connection between the connection terminal 500 and the connector 310.

[0046] Of course, in other embodiments, the cover plate can also be fixedly connected to the battery cover plate 400, that is, the cover plate cannot switch between the first position and the second position.

[0047] In optional embodiments, such as Figure 3 As shown, a notch 420 may be provided at the first edge 401 of the battery cover 400. The notch 420 may be opposite to the connector 310. This arrangement facilitates the insertion and removal of the connection terminal 500.

[0048] In an optional embodiment, the battery module may further include a frame 100, a circuit board 300 may be disposed within the frame 100, and a battery cover 400 may be connected to the frame 100.

[0049] Furthermore, the battery module may also include a battery cell 200, which is disposed within the frame 100 and can be electrically connected to the circuit board 300. The electrical energy of the battery cell 200 can be transmitted to the main body of the electronic device through the circuit board 300.

[0050] In an optional embodiment, the battery module may include at least two battery cells 200, each of which can be electrically connected to the circuit board 300. This configuration reduces the number of circuit boards 300 used, thereby reducing costs and the space occupied by the circuit boards 300, making the battery module structure more compact. This helps to reduce the overall size and weight of the battery module. Furthermore, all battery cells 200 can be uniformly detected and managed through a single circuit board 300, enabling more accurate balanced control and parameter adjustment of each battery cell 200, ensuring consistency of each battery cell 200 during charging and discharging, and thus extending the overall service life of the battery module.

[0051] In optional embodiments, such as Figure 1 and Figure 5 As shown, the battery module may include four battery cells 200, which can be distributed in pairs on both sides of the circuit board 300. This arrangement allows the four battery cells 200 to be rationally distributed on both sides of the circuit board 300, making full use of the internal space of the battery module and making the structure of the entire battery module more compact. Furthermore, this distribution method allows for a more rational circuit layout on the circuit board 300, facilitating the connection of each battery cell 200.

[0052] In an optional embodiment of this application, the battery cover 400 may be provided with scale markings. The scale markings may be positioned close to the observation window 410 and may be positioned along the insertion direction of the connection terminal 500. With this configuration, the operator can observe the size of the exposed portion 520 of the connection terminal 500 at the observation window 410 through the scale markings, thereby determining the insertion depth of the connection terminal 500 and whether the connection terminal 500 is inserted in place.

[0053] In optional embodiments of this application, such as Figure 9 As shown, connector 310 may include a retaining shell 311 and a pin 312. The retaining shell 311 can be connected to circuit board 300. The retaining shell 311 may be provided with a slot 3111 for at least a portion of the connecting terminal 500 to be inserted. The pin 312 may be located in the slot 3111 and electrically connected to circuit board 300. The connecting terminal 500 may be provided with a socket 510 for the pin 312 to be inserted. In this embodiment, the electrical connection between connector 310 and connecting terminal 500 can be achieved by inserting the socket 510 of connecting terminal 500 into the pin 312 of connector 310.

[0054] like Figure 9 As shown, an opening 3112 may be provided on the side wall of the fixing housing 311 near the battery cover 400. The opening 3112 can communicate with the slot 3111, and the end of the opening 3112 away from the groove of the slot 3111 can be flush with the end of the pin 312 away from the groove of the slot 3111. Figure 11 As shown, the connecting terminal 500 may also be provided with a plug portion 520. One end of the plug portion 520 away from the slot 3111 can be flush with one end of the socket 510 away from the slot 3111. The plug portion 520 can be inserted into the opening 3112, and the plug portion 520 can contact the side wall of the opening 3112 away from the slot 3111. In this embodiment, the cooperation between the plug portion 520 of the connecting terminal 500 and the opening 3112 ensures that the connecting terminal 500 is accurately aligned with the pin 312 when inserted into the slot 3111 of the connector 310, avoiding misalignment or displacement, thereby ensuring that the pin 312 can be smoothly inserted into the socket 510 of the connecting terminal 500, achieving a reliable electrical connection. Furthermore, the opening 3112 and the insertion part 520 allow the operator to directly observe the mating status of the connection terminal 500 and the connector 310 without removing the battery cover 400, thus facilitating monitoring whether the connection terminal 500 is properly inserted. Here, since the end of the opening 3112 facing away from the slot 3111 is flush with the end of the pin 312 facing away from the slot 3111, when the insertion part 520 contacts the side wall of the opening 3112 facing away from the slot 3111, it indicates that the connection terminal 500 and the connector 310 are properly mated.

[0055] Optionally, both the insertion portion 520 and the opening 3112 can be strip-shaped structures. Both the insertion portion 520 and the opening 3112 can extend along the insertion direction of the connecting terminal 500 and the connector 310. Furthermore, the opening 3112 and the insertion portion 520 can achieve a guiding engagement, which provides a guiding function for the insertion portion 520. By guiding the insertion portion 520, a good guiding effect can be achieved on the connecting terminal 500.

[0056] like Figure 2 and Figure 3 As shown, in the direction from the battery cover 400 to the circuit board 300, the orthogonal projection of the observation window 410 covers one end of the opening 3112 away from the slot 3111. This arrangement allows the operator to directly observe whether the insertion part 520 of the connection terminal 500 is in contact with the side of the opening 3112 away from the slot 3111 without removing the battery cover 400, thereby determining whether the connection terminal 500 is inserted correctly.

[0057] Of course, in other embodiments, the orthographic projection of the observation window 410 in the direction from the battery cover 400 to the circuit board 300 may not cover the end of the opening 3112 that is away from the slot 3111.

[0058] In optional embodiments, such as Figure 2 and Figure 3 As shown, the mounting housing 311 may have at least two openings 3112 on its side wall near the battery cover 400. These openings 3112 are spaced apart along the width of the circuit board 300. The connecting terminal 500 may have at least two insertion portions 520, each inserted into a corresponding opening 3112. This arrangement allows multiple connection points to be formed between the connecting terminal 500 and the mounting housing 311, thereby improving the connection stability between the connecting terminal 500 and the connector 310. This ensures a stable connection between the connecting terminal 500 and the connector 310 during the use of the battery module, reducing issues such as poor contact.

[0059] Of course, the fixed housing 311 may also have only one opening 3112 on the side wall near the battery cover 400, and the connection terminal 500 may also have only one plug-in part 520.

[0060] Optionally, the battery cover 400 may be provided with at least two observation windows 410, each of which may correspond one-to-one with each opening 3112. In this embodiment, each observation window 410 corresponds to one opening 3112, allowing operators to directly and accurately observe the fit between each plug part 520 of the connection terminal 500 and each opening 3112 through the observation window 410. For example, they can check whether each plug part 520 is fully inserted, whether there is any looseness or deformation, etc., thus enabling individual monitoring of each connection point. This ensures the reliability of the connection between the connector 310 and the connection terminal 500 and prevents misalignment of the connection terminal 500. Furthermore, compared to providing only one observation window 410 that covers the end of all openings 3112 away from the slot opening of the slot 3111, the size of each observation window 410 corresponding to one opening 3112 is relatively smaller, which better prevents dust or impurities from entering the interior of the battery module.

[0061] Of course, in other embodiments, the battery cover 400 may also have only one observation window 410, and in the direction from the battery cover 400 to the circuit board 300, the orthogonal projection of the observation window 410 covers one end of all openings 3112 away from the slot of the slot 3111.

[0062] Based on the battery module provided in the embodiments of this application, the embodiments of this application also provide an electronic device. The electronic device may include a device body, a connecting line, and the battery module described in any of the above embodiments. The device body can be electrically connected to the connecting terminal 500 of the battery module through the connecting line.

[0063] Alternatively, the electronic device can be a laptop or other device.

[0064] The beneficial effects achieved by the electronic device provided in this application embodiment are consistent with the beneficial effects achieved by the battery module provided in this application embodiment, and will not be repeated here.

[0065] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
