[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0045] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0046] refer to Figures 1 to 8 The embodiment of the present application discloses a battery, which can be a steel shell battery. Of course, it can also be other types, and the type of battery is not limited here. The disclosed battery includes a battery cell 10, a frame 20, a protective plate 30 and a connector 40, such as Figure 1 shown.

[0047] The frame 20 is a basic component that provides an installation base for components such as the battery cell 10, the protective plate 30, and the connector 40. In some embodiments, the frame 20 is provided with a storage space, and the battery cell 10 and the protective plate 30 are respectively arranged in the storage space. In this way, the frame 20 can accommodate the battery cell 10 and the protective plate 30, and limit the battery cell 10 and the protective plate 30 to ensure that the relative position between the battery cell 10 and the protective plate 30 is fixed to achieve a stable connection. Optionally, the frame 20 can surround the outside of the battery cell 10 and the protective plate 30, and to a certain extent, it can also provide a certain degree of protection for the battery cell 10 and the protective plate 30.

[0048] Exemplarily, the frame 20 can be a polygonal frame, a circular frame, etc., and can also be other shapes, which can be set according to the shape of the battery as required. In addition, the frame 20 can be made of a non-metal material, for example, a plastic material, a rubber material, etc., to play a certain insulation role.

[0049] The connecting piece 40 electrically connects the battery cell 10 and the protection plate 30 to transmit electric energy between the battery cell 10 and the protection plate 30 through the connecting piece 40. The connecting piece 40 can be arranged between the battery cell 10 and the protection plate 30 to facilitate the connection of the battery cell 10 and the protection plate 30.

[0050] In addition, the connecting piece 40 is fixedly connected with one of the battery cell 10 and the protection plate 30, and is detachably connected with the other one, so that the battery cell 10 and the protection plate 30 can be more easily separated during the dismounting process, facilitating the dismounting. The specific connection mode includes that the connecting piece 40 is fixedly connected with the battery cell 10, and the connecting piece 40 is detachably connected with the protection plate 30; or the connecting piece 40 is detachably connected with the battery cell 10, and the connecting piece 40 is fixedly connected with the protection plate 30.

[0051] Optionally, the fixed connection mode can be welding, riveting, bonding, etc., as long as it can ensure stable mechanical connection and electrical connection, and the specific mode is not limited. The detachable connection mode can be plug-in connection, clamping connection, screw connection, abutting connection, hooking connection, etc., as long as it can ensure stable mechanical connection and electrical connection, and the specific mode is not limited.

[0052] In some more specific embodiments, the connecting piece 40 is fixedly connected with the battery cell 10 by welding, and abuts against the protection plate 30.

[0053] In the embodiment of the present application, the frame 20 can provide an installation base for the battery cell 10, the protective plate 30, and the connector 40, and can limit the battery cell 10 and the protective plate 30 to prevent them from separating from each other. The battery cell 10 and the protective plate 30 can be connected via the connector 40 to facilitate signal transmission between the battery cell 10 and the protective plate 30, such as power signal transmission, control signal transmission, detection signal transmission, etc. The connector 40 is fixedly connected to one of the battery cell 10 and the protective plate 30 and detachably connected to the other. In this way, the battery cell 10 can be directly separated from the protective plate 30 during battery disassembly. Compared to the method of fixedly connecting the battery cell 10 and the protective plate 30 by welding, the embodiment of the present application can facilitate the disassembly and maintenance of the battery cell 10 and the protective plate 30, and can avoid deformation of the battery cell 10, the protective plate 30, etc. caused by large disassembly force, which may affect the normal use of the battery. In addition, the presence of welding defects that affect the stable and efficient transmission of signals between the battery cell 10 and the protection board 30 can be avoided, thereby preventing poor contact between the battery cell 10 and the protection board 30.

[0054] refer to Figure 6 In some embodiments, the connector 40 may include a first connecting piece 41, a second connecting piece 42, and a third connecting piece 43 connected in sequence. For example, the first connecting piece 41, the second connecting piece 42, and the third connecting piece 43 may all be polygonal conductive pieces. Of course, other shapes are also possible and are not specifically limited here.

[0055] The first connecting piece 41 and the second connecting piece 42 form a first angle, so that the first connecting piece 41 and the second connecting piece 42 can form an angled structure. This design method can help increase the thickness of the connector 40, thereby adapting to the scene where the distance between the battery cell 10 and the protective plate 30 is large. Of course, the angle range of the first angle can be set accordingly according to the distance between the battery cell 10 and the protective plate 30.

[0056] A second angle is formed between the third connecting piece 43 and the second connecting piece 42. This allows the connection between the second connecting piece 42 and the third connecting piece 43, or the third connecting piece 43, to contact the battery cell 10 or the protective plate 30, thereby increasing contact strength and stability. Furthermore, the range of the second angle can be set according to actual needs.

[0057] In the embodiment of the present application, the first connecting piece 41 is fixedly connected to one of the battery cell 10 and the protective plate 30, which can help increase the area of ​​the connection area, thereby improving the connection stability and preventing the current from passing through a smaller contact area and causing heating problems; the connection between the second connecting piece 42 and the third connecting piece 43 or the third connecting piece 43 abuts against the other of the battery cell 10 and the protective plate 30, which can help increase the contact strength and contact stability and ensure a stable connection between the connector 40 and the battery cell 10 or the protective plate 30.

[0058] In some embodiments, the first angle may range from 10° to 80°, including, for example, 10°, 30°, 45°, 50°, 60°, 75°, 80°, etc. Of course, it may also be other degrees, which are not specifically limited here. Based on this, the angle range of the first angle may be set accordingly according to the distance between the battery cell 10 and the protective plate 30. For example, when the distance is large, the angle range of the first angle may be increased so that the connector 40 has a larger thickness dimension, thereby meeting the scenario where the battery cell 10 and the protective plate 30 have a larger distance; conversely, when the distance is small, the angle range of the first angle may be reduced so that the connector 40 has a smaller thickness dimension, thereby meeting the scenario where the battery cell 10 and the protective plate 30 have a smaller distance.

[0059] The second angle may range from 100° to 170°, including, for example, 100°, 110°, 120°, 135°, 140°, 150°, 160°, 170°, etc. Of course, it may also be other degrees, which is not specifically limited here.

[0060] It should be noted that the second angle can be somewhat correlated with the first angle. The sum of the first and second angles can be no greater than 180°. This arrangement can better ensure that the first connecting piece 41 is fixedly connected to one of the battery cell 10 and the protective plate 30, and that the connection between the second connecting piece 42 and the third connecting piece 43 abuts the other, without causing the first connecting piece 41 and the third connecting piece 43 to be connected to the battery cell 10 and the protective plate 30, respectively.

[0061] In some specific embodiments, the end of the third connecting piece 43 facing away from the second connecting piece 42 can extend toward the first connecting piece 41. Of course, the third connecting piece 43 and the first connecting piece 41 can also be arranged parallel to each other. In the embodiments of the present application, the relative relationship between the first connecting piece 41 and the third connecting piece 43 is not specifically limited.

[0062] Continue to refer Figure 6In some embodiments, the first connecting piece 41 and the second connecting piece 42 can be connected by a first connecting arc 44, so as to relieve the stress concentration at the connection, thereby effectively relieving the problem of fracture of the connection due to stress concentration; and the connection can also avoid scratching the battery cell 10, the protection plate 30, the frame 20 and other components.

[0063] In addition, the second connecting piece 42 and the third connecting piece 43 can be connected by a second connecting arc 45, so as to relieve the stress concentration at the connection, thereby effectively relieving the problem of fracture of the connection due to stress concentration; and the connection can also avoid scratching the battery cell 10, the protection plate 30, the frame 20 and other components. Of course, the second connecting arc 45 can also increase the contact area between the connecting piece 40 and one of the battery cell 10 and the protection plate 30, so that a larger current can pass without heating problems.

[0064] Reference Figures 1 to 3 In some embodiments, the battery cell 10 can include two tabs 11, i.e., a positive tab and a negative tab, for transmitting electrical energy; accordingly, the battery pack can include two connecting pieces 40, which are respectively fixed to the corresponding tabs 11 and abut against the protection plate 30. Based on this arrangement, the electrical connection between the two tabs 11 and the protection plate 30 can be achieved by the two connecting pieces 40, which can ensure the stability of the connection and facilitate the disassembly of the battery cell 10 and the protection plate 30; in addition, the two connecting pieces 40 are spaced apart to avoid short circuit.

[0065] For example, the battery cell 10 can be a steel shell battery cell. In this case, the shell of the steel shell battery cell can serve as a negative electrode, and a positive tab is separately provided. In this case, one of the connecting pieces 40 can be connected to the shell of the steel shell battery cell, and the other connecting piece 40 can be connected to the positive tab.

[0066] In addition, the positive tab and the negative tab can each be in the form of a sheet or a pole, and can also be in other forms, which are not limited here.

[0067] To further improve the reliability and stability of the connection, the connecting piece 40 can be an elastic connecting piece that can be elastically deformed. Based on this, during assembly of the battery, the connecting piece 40 can be elastically deformed to store elastic potential energy, and the connecting piece 40 can be elastically contacted with one of the battery cell 10 and the protection plate 30, so that a pre-tightening force can be generated between the connecting piece 40 and the other of the battery cell 10 and the protection plate 30, thereby ensuring the reliability and stability of the connection.

[0068] Exemplarily, the connecting piece 40 can be a metal spring piece, such as a stainless steel spring piece, a copper spring piece, an aluminum spring piece, etc., and of course, can also be of other shapes and other materials, which are not specifically limited here.

[0069] In some more specific embodiments, the connection between the second connecting piece 42 and the third connecting piece 43, or the third connecting piece 43, can elastically abut against the other one of the battery cell 10 and the protection plate 30, to ensure the reliability and stability of the contact.

[0070] It should be noted here that, since the connecting piece 40 is an elastic connecting piece, it can generate an elastic force on the battery cell 10 and the protection plate 30. In the embodiments of the present application, the frame 20 can limit the battery cell 10 and the protection plate 30, respectively, to prevent them from being separated from each other under the elastic force, thereby ensuring the reliability of the connection between the battery cell 10 and the protection plate 30.

[0071] Reference Figures 1 to 5 To achieve the installation of the battery cell 10, the protection plate 30 and the connecting piece 40, the accommodation space can include a first installation space 21 and a second installation space 22, and the first installation space 21 and the second installation space 22 are in communication. Among them, the battery cell 10 is detachably arranged in the first installation space 21, the protection plate 30 is detachably arranged in the second installation space 22, and the connecting piece 40 is arranged in the communication region of the first installation space 21 and the second installation space 22 to connect the battery cell 10 and the protection plate 30.

[0072] Based on the structure of the frame 20 described above, the installation of the battery cell 10 and the protection plate 30 can be achieved to ensure the stability of the installation, the disassembly and assembly of the battery cell 10 and the protection plate 30 can be facilitated to facilitate the maintenance or replacement of the battery cell 10 and the protection plate 30, and the interference with the connecting piece 40 can be avoided to ensure that the battery cell 10 and the protection plate 30 can be connected through the connecting piece 40.

[0073] Exemplarily, the second installation space 22 can be located at one end of the first installation space 21, so that the protection plate 30 can be located at one end of the length or width of the battery cell 10, which can reduce the thickness of the battery to a certain extent.

[0074] In some embodiments, the frame 20 penetrates through both sides in the thickness direction of the battery in the region of the first installation space 21, thereby providing a larger installation space for the battery cell 10 to facilitate increasing the capacity of the battery cell 10 under the same thickness. Of course, the frame 20 can also penetrate through one side and block the other side in the thickness direction of the battery in the region of the first installation space 21, so as to limit the battery cell 10 on the other side to prevent the battery cell 10 from moving randomly.

[0075] In addition, the frame 20 is penetrated on both sides of the second installation space 22 along the thickness direction of the battery to provide a larger installation space for the protection plate 30. Of course, it is also possible that the frame 20 is penetrated on one side of the second installation space 22 along the thickness direction of the battery and the other side is blocked to limit the protection plate 30 on the other side to prevent it from moving freely.

[0076] refer to Figures 2 to 5 To further enhance the installation stability of the battery cell 10, the inner circumferential wall of the frame 20 facing the first installation space 21 may be provided with multiple first clips 23. Correspondingly, the outer circumferential edge of the battery cell 10 may be provided with multiple second clips 12. Thus, when the battery cell 10 is installed in the first installation space 21, the multiple first clips 23 engage with the multiple second clips 12. This arrangement effectively prevents the battery cell 10 from moving relative to the frame 20 along the thickness direction of the battery, thereby ensuring the stability of the battery cell 10 and facilitating assembly and disassembly of the battery cell 10.

[0077] In other embodiments, the battery cell 10 may be restricted from leaving the first installation space 21 by frictional resistance between the outer peripheral edge of the battery cell 10 and the side wall of the frame 20 facing the first installation space 21 .

[0078] For example, the plurality of first clips 23 may be distributed on the plurality of inner peripheral walls along the extension direction of the frame 20 , so as to increase the area of ​​the clipping region for the battery cell 10 and further improve the installation stability of the battery cell 10 .

[0079] In order to further improve the installation stability of the protection plate 30, the inner peripheral wall of the frame 20 facing the second installation space 22 can be provided with a limiting protrusion 24 protruding from the inner peripheral wall, such as Figures 2 to 5 As shown, in this way, when the protection plate 30 is installed in the second installation space 22 , the limiting protrusion 24 limits the protection plate 30 to prevent the protection plate 30 from being separated from the second installation space 22 .

[0080] For example, the limiting protrusion 24 can be provided on the inner peripheral wall of the frame 20 facing the second installation space 22 and adjacent to the first installation space 21. Of course, it can also be provided at other positions, which is not specifically limited here.

[0081] In other embodiments, the protection plate 30 may be restricted from leaving the second installation space 22 by frictional resistance between the protection plate 30 and the inner peripheral wall of the frame 20 facing the second installation space 22 .

[0082] refer to Figure 8In some embodiments, the battery can further include a through sleeve 50 at both ends, and the battery cell 10 is a steel shell battery cell. The frame 20 and the battery cell 10 and the protection plate 30 mounted to the frame 20 are all arranged in the sleeve 50. Therefore, the battery cell 10, the protection plate 30 and the frame 20 and other structures can be shielded by the sleeve 50, which can improve the appearance of the battery to some extent, and can also limit and protect the battery cell 10, the protection plate 30 and the frame 20 and other structures to some extent.

[0083] Exemplarily, the sleeve 50 can be a trademark sleeve, so as to present the parameters of the battery.

[0084] In some embodiments, one end of the frame 20 can be provided with a avoiding hole 25, as shown in Figure 4 、 Figure 5 and Figure 8 , the avoiding hole 25 is in communication with the second mounting space 22; correspondingly, the protection plate 30 can be provided with an electrical connecting piece 31, which is arranged opposite to the avoiding hole 25, and one end of the frame 20 is not shielded by the sleeve 50, so that the electrical connecting piece 31 is exposed, so as to connect the electrical connecting piece 31 with other electrical structures.

[0085] Exemplarily, the electrical connecting piece 31 can be a gold finger, a metal flexible plate or the like.

[0086] In the embodiment of the application, the assembly process of the battery is as follows:

[0087] The connecting piece 40 is fixedly connected to the battery cell 10; the protection plate 30 is mounted to the frame 20, the battery cell 10 with the welded connecting piece 40 is mounted to the frame 20, and the connecting piece 40 abuts against the protection plate 30 to form a power loop; finally, the sleeve 50 (such as a trademark sleeve) is mounted.

[0088] In summary, the battery in the embodiment of the application can be disassembled separately from the solid battery cell 10 and the protection plate 30, which is convenient for maintenance or replacement, and will not cause the battery to deform and affect the normal use of the battery.

[0089] The embodiments of the application are described above in combination with the drawings, but the application is not limited to the above specific embodiments, which are only illustrative but not limiting, and those skilled in the art can make many forms under the inspiration of the application without departing from the scope of the application and the protection scope of the claims.
