[0055] It should be noted that the embodiments and technical features in the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as the explanation and illustration of the purpose of the present application, and should not be regarded as improper limitation of the present application.

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the specific technical solutions of the present application will be further described in detail below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0057] Please refer to Figures 1-2 , Figure 1 the structure of the battery top cover provided by the embodiments of the present application is shown in the drawings. Figure 2 the partial cross-sectional structure of the battery top cover provided by the embodiments of the present application is shown in the drawings.

[0058] As shown in Figure 1 , the battery top cover includes a top cover plate 1, a transmission member 2, a sensor mechanism 3 and a communication mechanism 4.

[0059] In the present application, the top cover plate 1 is used to be installed on the top of the battery. The top cover plate 1 is also integrated with the transmission member 2, the sensor mechanism 3 and the communication mechanism 4.

[0060] The top cover plate 1 can be provided in a plate structure, and can be made of metal materials, such as aluminum materials, stainless steel or other metal alloys.

[0061] Please refer to Figure 2 , the transmission member 2 is provided through and sealed on the top cover plate 1, the inner end of the transmission member 2 is provided on the inner side of the top cover plate 1, and the outer end of the transmission member 2 is provided on the outer side of the top cover plate 1. The transmission member 2 is provided with a conductive connecting post 7, such as a connecting post 7 made of copper alloy or aluminum alloy. The signal or electric energy is transmitted through the connecting post 7, so that the inner side and the outer side of the top cover plate 1 can realize conduction and communication through the transmission member 2.

[0062] In some embodiments, the transmission member 2 can be welded on the opening 11 of the top cover plate 1 and tightly abutted with the top cover plate 1 to achieve sealing. In other embodiments, the transmission member 2 and the top cover plate 1 can also be connected by sealing means such as gluing. The sealing connection between the transmission member 2 and the top cover plate 1 can avoid the leakage of liquid and gas inside the battery. Alternatively, the transmission member 2 can be integrally formed with the top cover plate 1, that is, as a part of the top cover plate 1.

[0063] The sensor mechanism 3 on the battery top cover is detachably connected to the inner end of the transmission member 2. The sensor mechanism 3 can be detachably connected to the transmission member 2 by plug-in, screwing or other detachable fixing means. The sensor mechanism 3 can monitor the temperature and pressure data of the battery from the inside of the battery by being connected to the inner end of the transmission member 2, thereby facilitating the transmission of the temperature and pressure data of the battery to the battery management system.

[0064] The communication mechanism 4 on the battery top cover is detachably connected to the outer end of the transmission member 2. The communication mechanism 4 can be detachably connected to the transmission member 2 by plug-in, screwing or other detachable fixing means. The communication mechanism 4 can communicate and transmit the data signals collected by the sensor mechanism 3 through the transmission member 2 by being connected to the outer end of the transmission member 2, thereby transmitting the data collected by the sensor mechanism 3 to the battery management system. The communication mechanism 4 can transmit data signals in wired or wireless communication mode.

[0065] In the specific installation mode of the battery top cover, the transmission member 2 can be installed on the top cover plate 1 by welding, and then the sensor mechanism 3 and the communication mechanism 4 are respectively installed on the inner end and the outer end of the transmission member 2 and electrically connected to the transmission member 2, thereby realizing the transmission of the data signals of the sensor mechanism 3 to the communication mechanism 4 through the transmission member 2, and then transmitting signals to the battery management system by using the communication mechanism 4, so that the battery management system can analyze and manage according to the data signals collected by the sensor mechanism 3.

[0066] Moreover, since the detachable connection mode is provided, the sensor mechanism 3 and the communication mechanism 4 can be fixed by welding, which can simplify the installation process of the battery top cover, improve the production efficiency and reduce the installation and production cost. In addition, the detachable design enables the battery top cover to replace different sensor mechanisms 3 or communication mechanisms 4 according to different actual needs, thereby improving the applicability and maintainability of the battery top cover and reducing the maintenance cost.

[0067] In some embodiments, the sensor mechanism 3 and the communication mechanism 4 each include a plug-in part that is plug-in fixed with the transmission part 2. The plug-in part is internally provided with a terminal 6 that is electrically connected with the transmission part 2. The sensor mechanism 3 can include a sensor that is electrically connected with the terminal 6 and the transmission part 2 through the terminal 6. The communication mechanism 4 further includes a communication module that is electrically connected with the terminal 6 and the transmission part 2 through the terminal 6.

[0068] For ease of description, the plug-in part of the communication mechanism 4 can be defined as a first plug-in part 41, and the plug-in part of the sensor mechanism 3 can be defined as a second plug-in part 31. The terminal 6 internally provided in the plug-in part can be electrically connected with the connecting column 7 of the transmission part 2, so as to realize the transmission of signals or electric energy between the plug-in part and the connecting column 7. The number of the terminal 6 can be matched with the number of the connecting column 7, so that the terminal 6 can be matched and plug-in with the connecting column 7 on the transmission part 2. By setting the plug-in fixed mode of the plug-in part and the transmission part 2, the sensor mechanism 3, the communication mechanism 4 and the transmission part 2 can be quickly disassembled and assembled, so as to improve the production and maintenance efficiency of the battery top cover. Of course, the sensor can include but is not limited to common pressure sensors, temperature sensors and the like, and the specific type of the sensor can be determined according to actual needs. In some embodiments, the sensor can be arranged inside the sensor mechanism 3, or can be connected to the top cover plate 1 or the shell of the battery through the wire 5.

[0069] In some embodiments, the communication module of the communication mechanism 4 can include a wireless communication module that can use wireless transmission protocols including but not limited to Bluetooth for wireless communication. The wireless communication module can be connected with an external battery management system, so as to obtain the pressure, temperature and other data collected by the sensor mechanism 3. The above connection mode enables the data inside the battery to be transmitted to the outside of the battery through the transmission part 2, and then communicated through the wireless communication module, which can avoid the interference of the metal shell of the battery on the wireless signal reception and transmission, and improve the transmission reliability of the data. Moreover, the wireless communication module can reduce the use of wire harnesses, improve the assembly efficiency, and also avoid the problem of occupying space caused by too many wire harnesses.

[0070] The wireless communication module can be built-in in the communication mechanism 4, or fixed to the top cover plate 1 or other positions of the battery and electrically connected with the communication mechanism 4 through the wire 5. Of course, the specific implementation mode can be determined according to actual conditions.

[0071] Specifically, the transmission member 2 comprises a plug-in sleeve, the plug-in member is inserted into the plug-in sleeve and sealed against the plug-in sleeve and / or the top cover plate 1. For the convenience of description, the plug-in sleeve connected with the first plug-in member 41 of the transmission member 2 is defined as the first plug-in sleeve 21, and the plug-in sleeve connected with the second plug-in member 31 of the transmission member 2 is defined as the second plug-in sleeve 22. Specifically, the plug-in sleeve can be arranged around the connecting column 7, that is, the connecting column 7 can be arranged inside the plug-in sleeve. The structure of the plug-in sleeve can be matched with the plug-in member, and structures such as cylindrical, triangular or polygonal cross sections can be adopted to realize the positioning and installation between the plug-in member and the plug-in sleeve. Moreover, through the unified plug-in structure, different sensor mechanisms 3 or communication mechanisms 4 can be replaced and installed, so as to meet different use requirements and improve the applicability of the battery top cover. In addition, the plug-in member is sealed against the plug-in sleeve and / or the top cover plate 1, which can improve the sealing performance and effectively prevent the leakage of gas inside the plug-in sleeve.

[0072] Further, in order to improve the anti-loosening effect, the plug-in member is provided with a first clamping structure, the plug-in sleeve is provided with a second clamping structure, and the first clamping structure is clamped with the second clamping structure. The first clamping structure and the second clamping structure are clamped together, which can realize the clamping and fixing between the transmission member 2 and the communication mechanism 4 and the sensor mechanism 3, so as to avoid the communication mechanism 4 and the sensor mechanism 3 from easily falling off from the transmission member 2 under the action of vibration or external force, and improve the connection reliability.

[0073] Please refer to Figure 3 , which shows the structure of the communication mechanism 4 provided by the embodiment of the application.

[0074] Combined with Figures 1-2 In some embodiments, the first clamping structure comprises at least two oppositely arranged clamping arms 411, the second clamping structure comprises a clamping table 211 which is arranged outwardly along the radial direction of the plug-in sleeve, and one end of the clamping arm 411 is provided with a clamping portion 412 which is clamped with the clamping table 211.

[0075] Specifically, the clamping arm 411 is arranged on the first plug-in member 41 of the communication mechanism 4, and the clamping table 211 is arranged on the first plug-in sleeve 21 at the upper end of the transmission member 2. One end of the clamping arm 411 can be provided with a clamping portion 412 arranged in the direction of the first plug-in member 41, and the first plug-in sleeve 21 is provided with a clamping table 211 which protrudes outwardly along the radial direction of the first plug-in sleeve 21. By buckling the clamping portion 412 of the clamping arm 411 to the lower end of the clamping table 211, the clamping portion 412 is tightly abutted with the lower end of the clamping table 211, so as to realize the clamping and fixing between the communication mechanism 4 and the outer end of the transmission member 2.

[0076] When the communication mechanism 4 is installed with the transmission member 2, the clamping portion 412 of the clamping arm 411 can be pressed towards the clamping platform 211 of the transmission member 2, and the communication mechanism 4 is pressed towards the transmission member 2, at this time, the clamping portion 412 extrudes the upper end of the clamping platform 211, the clamping portion 412 is deformed outwardly under the interaction of the extrusion force, until the clamping portion 412 is clamped into the lower end of the clamping platform 211, and the quick installation without welding is realized. When the communication mechanism 4 is disassembled with the transmission member 2, an outward force can be applied to the clamping arm 411 to make the clamping portion 412 disengage from the clamping platform 211 to complete the quick disassembly, thereby improving the installation and disassembly efficiency between the communication mechanism 4 and the transmission member 2, and reducing the production and maintenance costs.

[0077] It can be understood that the clamping arm 411 can also be arranged on the second plug-in member 31 of the sensor mechanism 3, and the clamping platform 211 can also be arranged on the second plug-in sleeve 22 at the lower end of the transmission member 2, so as to realize the clamping between the sensor mechanism 3 and the transmission member 2.

[0078] In one implementation, in order to facilitate disassembly while ensuring clamping reliability, the other end of the clamping arm 411 extends to form a pressing portion 42 for facilitating the disengagement of the clamping portion 412 from the clamped state. By pressing the pressing portion 42, the clamping portion 412 of the clamping arm 411 can be deformed outwardly by the lever principle, so that the clamping portion 412 is disengaged from the clamping state with the clamping platform 211, and the communication mechanism 4 and the transmission member 2 are smoothly separated, or the sensor mechanism 3 and the transmission member 2 are smoothly separated, thereby improving the disassembly efficiency and reducing the maintenance cost.

[0079] Further, referring to the enlarged portion in Figure 2 , the pressing portion 42 and the first plug-in member 41 can be provided with a clamping ring 43 for preventing the clamping portion 412 from disengaging from the clamped state. During the installation of the communication mechanism 4 or the sensor mechanism 3, after the clamping portion 412 is clamped to the clamping platform 211, the clamping ring 43 can be sleeved in the gap between the pressing portion 42 and the first plug-in member 41. When the clamping ring 43 is installed between the pressing portion 42 and the plug-in member, the pressing portion 42 can be supported, avoiding the pressing portion 42 from being pressed by mistake to cause the plug-in member to be loose, thereby improving the connection reliability.

[0080] Please refer to Figure 4 , which shows the structure of the transmission member 2 and the sensor mechanism 3 provided by the embodiments of the present application.

[0081] In combination with Figures 1-2 , in some other embodiments, the first clamping structure includes a clamping member 311, and the second clamping structure includes a clamping hole 221, and the clamping member 311 is clamped into the clamping hole 221, so as to realize the clamping and fixation between the plug-in member and the plug-in sleeve.

[0082] Specifically, the clamping piece 311 is arranged on the second plug-in piece 31 of the sensor mechanism 3, and the clamping hole 221 is arranged on the second plug-in sleeve 22 at the lower end of the transmission piece 2. The clamping piece 311 can be provided with a buckle protrusion, and the clamping hole 221 is arranged through the second plug-in sleeve 22, thereby forming a structure that can be used for clamping and fixing the clamping piece 311. The buckle protrusion on the clamping piece 311 is arranged corresponding to the clamping hole 221, and the buckle protrusion on the clamping piece 311 can pass into the clamping hole 221 from the inside of the second plug-in sleeve 22, thereby realizing clamping and fixing between the sensor mechanism 3 and the transmission piece 2. Of course, the clamping mode between the clamping piece 311 and the clamping hole 221 can be adjusted according to requirements, and the present application does not limit this.

[0083] It can be understood that the clamping piece 311 can also be arranged on the first plug-in piece 41 of the communication mechanism 4, and the clamping hole 221 can also be arranged on the first plug-in sleeve 21 at the upper end of the transmission piece 2, thereby realizing clamping and fixing between the communication mechanism 4 and the transmission piece 2.

[0084] In one of the implementation manners, the plug-in piece is provided with an avoiding groove 32 on the inside of the clamping piece 311, which facilitates the deformation of the clamping piece 311 away from the clamping hole 221 under external force, thereby realizing the disengagement of the plug-in piece and the plug-in sleeve from the clamping state. At the same time, the avoiding groove 32 also improves the deformation ability of the clamping piece 311, thereby facilitating the clamping of the clamping piece 311 into the clamping hole 221, improving the disassembly efficiency, and reducing the maintenance cost of the communication mechanism 4 or the sensor mechanism 3.

[0085] Please refer to Figure 1 In order to improve the sealing effect between the plug-in piece and the plug-in sleeve, and / or between the plug-in piece and the top cover plate 1, a sealing gasket 8 is arranged at the abutting position between the plug-in piece and the plug-in sleeve, and / or at the abutting position between the plug-in piece and the top cover plate 1. The sealing gasket 8 can be a ring-shaped structure and is composed of rubber or other high-molecular materials with deformation ability. By arranging the sealing gasket 8 at the abutting position between the plug-in piece and the plug-in sleeve, and / or at the abutting position between the plug-in piece and the top cover plate 1, the sealing gasket 8 with certain deformation ability not only plays a role in improving the sealing performance and effectively preventing the leakage of gas inside the plug-in sleeve, but also improves the reliability of clamping and fixing, so that the abutting between the plug-in piece and the plug-in sleeve, and / or between the plug-in piece and the top cover plate 1 is more compact, thereby avoiding loosening.

[0086] Please refer to Figure 5 Another structure of the transmission piece 2 provided by the embodiment of the present application is shown in the figure.

[0087] As Figure 5As shown, the transmission component 2 may include a mounting base 23, and the connecting post 7 may be disposed on the mounting base 23. Furthermore, an insulating sleeve 24 may be provided between the connecting post 7 and the mounting base 23. The insulating sleeve 24 may be made of common insulating sintered materials such as silicates and alumina, which can not only avoid signal interference of the top cover plate 1 to the connecting post 7, but also form an effective fixing structure, playing a certain role in fixing and sealing.

[0088] Please see Figure 6 The figure shows the inner structure of the battery top cover provided in an embodiment of this application.

[0089] like Figure 6 As shown, combined with Figure 1 The battery top cover also includes a terminal post 12, which is disposed through and sealed on the top cover plate 1. The terminal 6 and / or the transmission element 2 are electrically connected to the terminal post 12 via a wire 5.

[0090] The electrode post 12 can be electrically connected to the terminal 6 or the transmission component 2 via the wire 5, providing power to the sensor in the sensor mechanism 3 and the communication module of the communication mechanism 4. This is particularly beneficial for sensors located inside the battery. Traditionally, if a sensor is located inside the battery, it needs to be connected to an external power source via the transmission component 2 to power the sensor and ensure its normal operation. If the terminal 6 and / or the transmission component 2 are electrically connected to the electrode post 12 via the wire 5, an external power source is unnecessary, reducing the use of wiring harnesses and thus reducing space requirements.

[0091] In another embodiment, the battery top cover also includes an insulating member 9, which is disposed on the inner side of the top cover plate 1. An avoidance hole 91 is provided on the insulating member 9 at the position corresponding to the sensor mechanism 3, and a protective sleeve 92 is provided on the insulating member 9 around the avoidance hole 91.

[0092] Specifically, the clearance hole 91 can be positioned opposite to the opening 11 of the top cover plate 1, and its size is comparable to that of the opening 11 of the top cover plate 1, thereby facilitating the passage of the transmission component 2 or the sensor mechanism 3. The protective sleeve 92 can be integrally formed with the insulating component 9, or it can be separately installed. The protective sleeve 92 can prevent the sensor mechanism 3 from becoming loose due to misoperation, thus preventing loosening and improving the connection stability of the sensor mechanism 3.

[0093] Please see Figure 7 The figure shows the structure of the battery provided in an embodiment of this application.

[0094] like Figure 7As shown, the battery includes a housing 10, an electrode assembly 20, and a battery top cover 30. Specifically, the housing 10 includes a receiving cavity with an opening, and the electrode assembly 20 is installed in the receiving cavity. The battery top cover 30 closes onto the opening, so that the battery top cover 30, the electrode assembly 20, and the housing 10 together constitute a complete battery.

[0095] The battery top cover 30 is used to mount on the top of the battery. The battery top cover 30 also integrates a transmission component, a sensor mechanism, and a communication mechanism. The electrode assembly 20 is connected to the terminals on the battery top cover 30 and can be electrically connected to the transmission component via wires to power the sensor mechanism and the communication mechanism.

[0096] Meanwhile, the battery top cover 30 may include the battery top cover 30 of any of the above embodiments, and the structural implementation of the battery top cover 30 will not be described in detail in this application.

[0097] The battery in this application features a transmission component mounted on the top cover of the battery cover, with a sensor mechanism detachably connected to the inner end of the transmission component and a communication mechanism detachably connected to the outer end of the transmission component. This detachable connection eliminates the need for welding the sensor and communication mechanisms, simplifying the battery cover installation process, improving production efficiency, and reducing installation costs. Furthermore, the detachable design allows for the replacement of different sensor or communication mechanisms to meet varying needs, thereby enhancing the battery's applicability and maintainability while reducing maintenance costs.

[0098] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0099] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings.
