It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0032] See also Figure 1 , Figure 1 It is an exploded view of an implementation method of a backup power supply of the present application.

[0033] In this embodiment, the backup power supply 1 includes a battery mounting mechanism 10 and a plurality of battery cells 20 , and the plurality of battery cells 20 are connected to the battery mounting mechanism 10 .

[0034] It is worth noting that the backup power supply 1 can specifically be a BBU, a functional component for providing emergency power support, mainly used to prevent data loss and business interruption caused by mains failure. The BBU provides a short power supply to the system when the power is interrupted, ensuring that key equipment can continue to operate or shut down safely, thereby protecting the integrity of data and the system.

[0035] BBU will automatically take over the power supply task when the power is interrupted, usually within a few minutes. It can be used in core IT (Information Technology) equipment such as servers, data centers, and communication base stations to ensure that data and systems can still operate normally when power problems occur. BBU is usually used in combination with UPS (Uninterruptible Power Supply), diesel generators and other equipment to form a multi-level backup power solution to meet different time and power requirements; it can be embedded in the server cabinet in a distributed manner and flexibly configured as needed.

[0036] Among them, multiple battery cells 20 constitute the core energy storage unit of the backup power supply 1, providing the required power support; the battery mounting mechanism 10 provides physical support and fixing structure for the battery cells 20; multiple battery cells 20 are connected to the battery mounting mechanism 10 in a specific manner to form a modular pack assembly, namely the backup power supply 1.

[0037] For details, please refer to Figure 2-Figure 4 ,in, Figure 2 yes Figure 1 A schematic diagram of the structure of an embodiment of a positive electrode support and a negative electrode support in a parallel support of a backup power supply, Figure 3 yes Figure 2 Schematic diagram of the structure of the positive electrode bracket and the negative electrode bracket from another perspective. Figure 4 yes Figure 2 A schematic structural diagram of the positive electrode support from another perspective. In this embodiment, the battery mounting mechanism specifically includes at least one parallel bracket 11.

[0038] Among them, a battery installation mechanism 10 provided in the present application is applied to a backup power supply 1, such as a BBU of a server, and is specifically used to arrange multiple battery cells 20 in a specific manner to form a modular pack assembly. Of course, in other embodiments, the battery installation mechanism 10 can also be specifically used in a backup power supply of a communication device, a medical device, or any other reasonable electronic device, and this embodiment does not limit this.

[0039] Specifically, each parallel bracket 11 consists of two parts, namely a positive electrode bracket 111 and a negative electrode bracket 112 that can be detachably connected to the positive electrode bracket 111, so that when maintenance or replacement of the battery is required, the negative electrode bracket 112 can be easily removed to access or remove the battery cell 20.

[0040] The positive electrode support 111 is provided with two rows of first receiving holes 1101, and the corresponding negative electrode support 112 is provided with corresponding second receiving holes 1102. Each set of corresponding first receiving holes 1101 and second receiving holes 1102 is intended to accommodate the positive and negative electrodes of a single battery cell 20. This means that the battery cell 20 will be placed between the two supports, with its positive and negative electrodes respectively located in their respective receiving holes.

[0041] Among them, the line connecting the center points of two adjacent first accommodating holes 1101 in different rows on the positive electrode bracket 111 forms a set angle a with the first direction y, so as to form a first air duct 1103 on the parallel bracket 11 to provide a heat dissipation channel for each battery cell 20.

[0042] It is worth mentioning that the angle in this article refers to the minimum positive angle formed by the intersection of two straight lines, which is called the angle between the two straight lines (or vectors), usually recorded as ∠α. The range of the angle ∠α between the two straight lines is 0≤∠α≤90 degrees.

[0043] The set angle a specifically refers to the angle between the straight line where the center points of two adjacent first accommodating holes 1101 in different rows on the positive electrode support 111 are connected and the straight line where the first direction y is located. The set angle a is greater than 0, that is, the battery cells 20 are not arranged at right angles, but are arranged at a certain tilt angle, and specifically in the first direction y, such as the height direction, each layer of battery cells 20 is staggered according to a certain height difference, and is not parallel to the first direction y.

[0044] It is understandable that each second accommodating hole 1102 on the negative electrode support 112 will also correspond to the specific corresponding features of each first accommodating hole 1101, that is, the line connecting the center points of two adjacent second accommodating holes 1102 in different rows will also form a set angle a with the first direction y.

[0045] In the above scheme, each layer of battery cells 20 is staggered with a certain height difference in the first direction y by the battery installation mechanism 10, so as to arrange more battery cells 20 more closely in a limited space and effectively reduce the overall height of the product, so as to be applied to any reasonable electronic equipment with limited spatial structure layout, especially in any reasonable electronic equipment with a standard cabinet unit height of 1U such as server cabinets, distribution cabinets, communication equipment, etc., and the application range is wider; and because the negative electrode bracket 112 is detachable, when it is necessary to repair or replace a single battery cell 20 in the battery module, the operation is more convenient; arranging the battery cells 20 at a certain inclination angle helps to improve the cooling effect, reduce mechanical stress or simplify the manufacturing process; non-vertically arranged battery cells 20 are also conducive to air circulation or heat sink arrangement, thereby improving the heat dissipation performance of the entire battery module; the detachable design provides the possibility of flexible configuration, and the number and arrangement of the battery cells 20 can be adjusted according to different application requirements. The battery cell 20 mounting mechanism is particularly suitable for data centers, communication base stations, industrial automation systems, medical equipment vehicles, energy storage systems and other applications that require efficient management and arrangement of multiple battery cells. It not only supports large-scale production and automated assembly lines, but also provides convenience for subsequent product services and support.

[0046] It is worth mentioning that electronic equipment with a standard cabinet unit height of 1U is widely used in data centers, communication base stations, server rooms and other occasions. These devices are usually compactly designed to maximize space utilization and comply with industry standards for easy installation and maintenance. The following are several common 1U height electronic equipment:

[0071] Medical equipment interface module: used to connect and integrate data transmission between hospital information systems and other medical equipment.

[0072] Summary 1U height electronic equipment has become an indispensable part of data centers and various professional environments due to its compact design and standardized installation method. They not only save valuable physical space, but also improve the scalability and maintainability of the system. With the advancement of technology, more and more functions are integrated into smaller spaces, which makes the application scope of 1U equipment continue to expand.

[0073] In some embodiments, the set angle a between the line connecting the center points of two adjacent first accommodating holes 1101 in different rows and the first direction y can be specifically 0-45 degrees, and preferably 1-30 degrees, so that when each battery cell 20 is of standard size, the maximum distance between two rows of battery cells 20 in the first direction y, that is, the height of two layers of battery cells 20 can be maintained within 37.9 mm, so that the overall height of the modular pack assembly formed by each battery cell 20 fixedly installed by a plurality of parallel brackets 11 is within the range of 1U, and at the same time, gap air ducts are formed between each battery cell 20 in the pack assembly, which is conducive to air convection heat dissipation.

[0074] In some embodiments, multiple parallel brackets 11 are arranged along the second direction x, and among two adjacent parallel brackets 11, the positive electrode bracket 111 of one parallel bracket 11 is detachably connected to the negative electrode bracket 112 of another parallel bracket 11 to ensure that a series or parallel circuit can be formed between the battery cells 20, while providing a flexible electrical connection solution.

[0075] The second direction x is perpendicular to the first direction y, that is, a plurality of parallel brackets 11 are arranged along two mutually perpendicular directions to form a grid structure, so that the battery module can compactly arrange a large number of battery cells 20 on a plane, thereby improving space utilization.

[0076] Adjacent parallel-group brackets 11 are interconnected through the detachable connection between the positive electrode bracket 111 and the negative electrode bracket 112 , which not only simplifies the electrical connection between the battery cells 20 , but also facilitates the operation of maintaining and replacing the battery cells 20 .

[0077] It can be understood that the several battery cells 20 arranged by the parallel group bracket 11 are grouped or together, and the positive and negative directions of the battery cells 20 in the group are respectively consistent, but opposite to the positive and negative directions of the front or rear group of battery cells 20 arranged by another adjacent parallel group bracket 11. They are arranged side by side, and the adjacent parallel groups are connected end to end. Multi-stage series connection is achieved by extending along the axial direction of the battery cell 20, that is, the second direction x.

[0078] The cells 20 in each parallel group are staggered at a certain height difference and fixed by a positive electrode bracket 111 and a negative electrode bracket 112. The positive electrode bracket 111 and the negative electrode bracket 112 are detachably connected, and then each parallel group is detachably connected to each other to form a whole.

[0079] In some embodiments, the positive electrode bracket 111 and the negative electrode bracket 112 in each parallel bracket 11 are specifically connected by a clamping portion. Among them, the positive electrode bracket 111 is provided with at least one first clamping portion 1111, and the negative electrode bracket 112 is provided with a second clamping portion 1121 to cooperate with the first clamping portion 1111 on the positive electrode bracket 111. Each first clamping portion 1111 in the same parallel bracket 11 is configured to be able to be accurately buckled with a second clamping portion 1121 to ensure a stable connection between the positive electrode bracket 111 and the negative electrode bracket 112, and also facilitate disassembly and maintenance.

[0080] In some embodiments, the positive electrode bracket 111 is provided with first clamping portions 1111 on opposite sides along the third direction z, and the negative electrode bracket 112 is provided with second clamping portions 1121 on opposite sides along the third direction z, respectively. The first clamping portions 1111 in the same parallel bracket 11 correspond one to one with the second clamping portions 1121 of the negative electrode bracket 112, ensuring that each first clamping portion 1111 can be tightly fastened with each corresponding second clamping portion 1121 to form a stable connection, thereby realizing the connection between the positive electrode bracket 111 and the negative electrode bracket 112 in the same parallel bracket 11, and can also form a clamp from the opposite sides of each parallel bracket 11, further stabilizing the connection between the positive electrode bracket 111 and the negative electrode bracket 112, simplifying the assembly process, providing the possibility of quick disassembly and assembly, and facilitating the maintenance and replacement of the battery cell 20.

[0081] The third direction z, the second direction x and the first direction y are perpendicular to each other.

[0082] It is understandable that the snap-on design allows the operator to quickly connect or separate the positive electrode bracket 111 and the negative electrode bracket 112, reducing assembly time and complexity. The design of the snap-on portion ensures a reliable mechanical connection between the positive and negative electrode brackets 112, and remains stable even under vibration or impact conditions. This connection method supports modular battery assembly, and the size and shape of the battery module can be flexibly adjusted according to demand. When a specific battery cell 20 needs to be repaired or replaced, the target battery cell 20 can be easily removed or replaced by loosening the corresponding snap-on portion without affecting other parts. The design of the snap-on portion can adapt to different sizes and specifications, and is suitable for various types of battery cells 20, increasing the versatility and flexibility of the system. The battery cell 20 installation mechanism with a snap-on structure significantly improves the design and application efficiency of the battery module by providing the characteristics of quick assembly, stable connection and easy maintenance.

[0083] In some embodiments, the number of the first clamping parts 1111 in each positive electrode bracket 111 can be any reasonable number such as 2, 3 or 6, and the number of each second clamping part 1121 can also be any reasonable number such as 2, 3 or 6; and the structure of different first clamping parts 1111 can be the same or different, and the structure of the corresponding second clamping parts 1121 can be the same or different, and can be specifically in the form of matching snap-fits, and / or one of them is a column of any reasonable shape such as partial triangular prism, partial cylinder or partial elliptical cylinder, and the other is in the form of a matching groove or blind hole, which is not limited in the present application.

[0084] In some embodiments, a first positioning protrusion 1115 is provided on the positive electrode support 111, and a first positioning groove 1125 corresponding to the first positioning protrusion 1115 is provided on the negative electrode support 112 to ensure accurate alignment between the positive electrode support 111 and the negative electrode support 112. When the positive electrode support 111 and the negative electrode support 112 of the same parallel support 11 are clamped, the first positioning protrusion 1115 extends into the first positioning groove 1125 to ensure accurate alignment of the two in the horizontal direction. At the same time, the first clamping portion 1111 passes through the first positioning protrusion 1115 and is buckled with the second clamping portion 1121 to ensure a stable connection in the vertical direction.

[0085] It is understandable that the design of the first positioning protrusion 1115 and the first positioning groove 1125 ensures the precise alignment between the positive electrode bracket 111 and the negative electrode bracket 112, avoiding the risk of poor contact or short circuit due to misalignment. Through the cooperation of the first positioning protrusion 1115 and the first positioning groove 1125, and the snap fit of the first clamping portion 1111 and the second clamping portion 1121, a multi-dimensional stable connection is achieved, reducing the possibility of loosening or falling off. The positioning and clamping design allows the positive electrode bracket 111 and the negative electrode bracket 112 to be quickly connected or separated, greatly simplifying the assembly and maintenance process. The clear positioning structure reduces possible errors during assembly and improves production efficiency and product quality. Precise alignment and stable connection help maintain good electrical contact, reduce resistance losses, and improve the overall performance of the system.

[0086] In some embodiments, the positive electrode support 111 is provided with first positioning portions 1116 on opposite sides along the first direction y, and the negative electrode support 112 is provided with second positioning portions 1126 on opposite sides along the first direction y, which correspond to the first positioning portions 1116 on the positive electrode support 111, and are used to achieve precise alignment of the two. The first positioning portion 1116 is provided with a second positioning protrusion 1117, and the second positioning portion 1126 is provided with a second positioning protrusion 1117, which is used to match the second positioning protrusion 1117 on the positive electrode support 111, and is used to receive and fix the second positioning protrusion 1117. When the positive electrode support 111 and the negative electrode support 112 in the same parallel support 11 are clamped, the first positioning portion 1116 and the second positioning portion 1126 will abut against each other, and the second positioning protrusion 1117 will extend into the second positioning protrusion 1117, so as to ensure the precise alignment of the positive electrode support 111 and the negative electrode support 112 in the horizontal direction, and provide an additional mechanical locking function to prevent accidental loosening.

[0087] It is understandable that the design of the first positioning portion 1116 and the second positioning portion 1126 ensures the precise alignment between the positive electrode support 111 and the negative electrode support 112, avoiding the risk of poor contact or short circuit caused by misalignment. And because the positioning portions are arranged on both sides of the positive electrode support 111 and the negative electrode support 112, multiple points of contact are formed during connection, which enhances the overall stability of the connection. Through the cooperation of the second positioning protrusion 1117 and the second positioning protrusion 1117, and the abutment of the first positioning portion 1116 and the second positioning portion 1126, a multi-dimensional stable connection is achieved, reducing the possibility of loosening or falling off. The positioning and clamping design allows the positive electrode support 111 and the negative electrode support 112 to be quickly connected or separated, greatly simplifying the assembly and maintenance process. The clear positioning structure reduces possible errors during assembly and improves production efficiency and product quality. Accurate alignment and stable connection help maintain good electrical contact, reduce resistance loss, and improve the overall performance of the system.

[0088] Furthermore, in some embodiments, the first positioning portion 1116 on the positive electrode bracket 111 is provided with positioning arc surfaces (not shown) on both sides along the third direction z, and the second positioning portion 1126 on the negative electrode bracket 112 is also provided with positioning arc surfaces on both sides along the third direction z, respectively. The positioning arc surfaces are used to wrap the battery cells when the battery cells are installed in the battery mounting mechanism to provide additional fixation and support.

[0089] It is understandable that when the positive pole bracket 111 and the negative pole bracket 112 in the same parallel bracket 11 are clamped, the first positioning portion 1116 and the second positioning portion 1126 are abutted, and the second positioning protrusion 1117 extends into the second positioning protrusion 1117. At the same time, the positioning arc surface wraps the battery cell to ensure the stable position of the battery cell in the installation mechanism. Since the positioning arc surface is arranged on both sides of the first positioning portion 1116 and the second positioning portion 1126, multiple points of contact and wrapping are formed when the battery cell is installed, which enhances the fixing effect of the battery cell and provides better mechanical protection. The design of the positioning arc surface can significantly improve the fixing effect and connection reliability of the battery cell in the battery installation mechanism. And the close contact formed between the positioning arc surface and the battery cell is conducive to heat conduction, combined with appropriate heat dissipation design, it can effectively improve the heat dissipation performance of the battery cell.

[0090] In some embodiments, the positive pole support 111 and the negative pole support 112 are also provided with heat dissipation holes (not shown in the figure), wherein the heat dissipation holes in the positive pole support 111 are located between two adjacent first receiving holes 1101, and are intended to promote the transfer of heat from the battery cell to the outside air. The heat dissipation holes in the negative pole support 112 are located between two adjacent second receiving holes 1102, and are also intended to promote the transfer of heat from the battery cell to the outside air. The heat dissipation holes on the positive pole support 111 and the negative pole support 112 are aligned and connected along the second direction x to form a continuous second air duct 1104 to ensure that the airflow can smoothly pass through the entire support structure from one side to take away the heat generated by the battery cell, thereby achieving efficient heat dissipation.

[0091] It is understandable that through the design of the heat dissipation through-holes, heat can be quickly conducted from the surface of the battery cell to the bracket, and carried away by the external airflow through the second air duct 1104, avoiding local overheating. The heat dissipation through-holes are distributed between adjacent accommodation holes to ensure that each battery cell can obtain a uniform cooling effect and prevent problems caused by poor heat dissipation in certain areas. The existence of the heat dissipation through-holes does not weaken the overall structural strength of the bracket. On the contrary, the rigidity of the bracket can be further enhanced through reasonable design, such as adding support ribs and other measures. The design of the heat dissipation through-holes usually adopts stamping or mold forming processes, which is easy to mass produce and quality control, and reduces manufacturing costs. Effective heat dissipation design extends the service life of the battery cells and other components, reduces the failure rate caused by overheating, and improves the reliability and safety of the entire system. The presence of the heat dissipation through-holes provides a way for heat to be quickly conducted, and the second air duct 1104 optimizes the airflow path and improves the heat dissipation efficiency.

[0092] In some embodiments, at least one slot 1112 is provided on the positive electrode bracket 111, and a clamping portion 1122 corresponding to the slot 1112 is provided on the negative electrode bracket 112 to ensure a stable connection between two adjacent parallel brackets 11. In the same parallel bracket 11, the clamping portion 1122 on the negative electrode bracket 112 can be clamped into the slot 1112 in another adjacent parallel bracket 11 to connect the two adjacent parallel brackets 11, thereby realizing a quick connection of multiple parallel brackets 11 through a simple plug-in action.

[0093] It is understandable that the design of the card slot 1112 and the clamping portion 1122 allows two adjacent parallel brackets 11 to be quickly connected or separated, greatly simplifying the assembly and maintenance process. Through the cooperation of the card slot 1112 and the clamping portion 1122, multi-point contact is achieved, the possibility of loosening or falling off is reduced, and the stability and reliability of the connection are ensured. This design allows the battery system to be flexibly expanded according to demand, and the newly added parallel bracket 11 can be easily integrated with the existing structure, improving the scalability of the system. The clear position of the card slot 1112 and the clamping portion 1122 reduces possible errors during the assembly process and improves production efficiency and product quality. The presence of the card slot 1112 and the clamping portion 1122 provides a simple and effective solution for connection, ensuring that multiple parallel brackets 11 can be quickly and firmly connected together, suitable for a variety of application scenarios and technical requirements.

[0094] Furthermore, in some embodiments, the positive electrode bracket 111 in each parallel bracket 11 is provided with a clamping groove 1112 on opposite sides along the second direction x, and the negative electrode bracket 112 is provided with a clamping portion 1122 protruding along the second direction x corresponding to the position of the clamping groove 1112 on the positive electrode bracket 111. The clamping groove 1112 on a parallel bracket 11 corresponds one to one with the clamping portion 1122 on the adjacent parallel bracket 11, that is, the clamping portion 1122 can be tightly fitted into the clamping groove 1112 of the positive electrode bracket 111 to ensure that the two adjacent parallel brackets 11 are firmly connected.

[0095] Among them, the clamping portion 1122 of the negative electrode bracket 112 in the parallel bracket 11 is clamped into the clamping groove 1112 of the positive electrode bracket 111 in another adjacent parallel bracket 11 to achieve the connection between the two adjacent parallel brackets 11, ensuring the firmness of the mechanical connection, and forming a clamp from the opposite sides of each parallel bracket 11, further stabilizing the connection between the two adjacent parallel brackets 11, and allowing disassembly and assembly, which is convenient for maintenance and replacement of the battery cell 20.

[0096] It is understandable that the design of the slot 1112 and the clamping portion 1122 allows the positive electrode bracket 111 and the negative electrode bracket 112 to be quickly engaged or separated, reducing assembly time and complexity and improving production efficiency. The tightly fitting slot 1112 and the clamping portion 1122 provide a reliable mechanical connection that remains stable even under vibration or impact conditions, reducing the risk of loosening. The design of the slot 1112 and the clamping portion 1122 can adapt to different sizes and specifications, and is suitable for various types of battery cells 20, increasing the versatility and flexibility of the system.

[0097] Among them, the outer shape of the parallel bracket 11 composed of the connected positive bracket 111 and the negative bracket 112 can be specifically a rectangular parallelepiped, and the corresponding first clamping portion 1111 and the second clamping portion 1121 can be specifically arranged on the opposite side surfaces of one pair of the parallel bracket 11, and the clamping groove 1112 and the clamping portion 1122 are arranged on the opposite side surfaces of the other pair.

[0098] In some embodiments, the number of the slots 1112 in each positive electrode bracket 111 can be any reasonable number such as 2, 4 or 6, and the number of each clamping portion 1122 can also correspond to any reasonable number such as 2, 4 or 6; and the structures of different clamping portions 1122 can be the same or different, and can be any reasonable shape such as a triangular prism, a partial cylinder or a partial elliptical cylinder, and the corresponding slots 1112 are in the form of matching grooves or blind holes; and each clamping portion 1122 and the slot 1112 can also be in the form of matching snap-fits, which is not limited in the present application.

[0099] Please continue to refer to Figure 5 , Figure 5 yes Figure 1 A structural schematic diagram of an implementation example of a battery connecting piece in a parallel bracket of a backup power supply.

[0100] In some embodiments, the parallel bracket 11 also includes a battery connecting plate 113, the battery connecting plate 113 includes a positive connecting plate 1131 and a negative connecting plate 1132, the positive connecting plate 1131 is arranged on the side of the positive bracket 111 facing the negative bracket 112, corresponding to each first accommodating hole 1101 in the positive bracket 111, the positive connecting plate 1131 is provided with a positive connecting portion 11311 for connecting the positive electrode of each battery cell 20.

[0101] The negative electrode connecting piece 1132 is disposed on one side of the negative electrode support 112 facing the positive electrode support 111 . Corresponding to each second receiving hole 1102 in the negative electrode support 112 , the negative electrode connecting piece 1132 is provided with a negative electrode connecting portion 11321 for connecting the negative electrode of each battery cell 20 .

[0102] It is understandable that each positive electrode connection portion 11311 and its corresponding negative electrode connection portion 11321 in the parallel bracket 11 are respectively used to set the positive electrode and negative electrode of a battery cell 20. In this way, the positive electrode connection sheet 1131 can connect the positive electrodes of all battery cells 20 together, while the negative electrode connection sheet 1132 is responsible for connecting the negative electrodes of all battery cells 20, thereby forming a unified electrical connection network.

[0103] Among them, several battery cells 20 form a group, and the positive and negative directions of the battery cells 20 in the group are respectively consistent; the battery cells 20 in the group are connected together by the positive and negative connecting plates 1131 and the negative connecting plates 1132 to form a parallel group; the positive and negative directions of several adjacent battery cells 20 are respectively consistent, but opposite to the positive and negative directions of the battery cells 20 in the previous group, and are arranged side by side; the positive and negative electrodes of adjacent parallel groups are connected together by battery connecting plates 113 to achieve multi-stage series connection.

[0104] Through the dedicated positive electrode connecting piece 1131 and the negative electrode connecting piece 1132, the positive and negative electrodes of all battery cells 20 can be efficiently connected, reducing the complexity and time required for traditional wiring methods. The design of the connecting piece provides a more stable electrical connection, reduces the risk of poor contact or looseness, and improves the reliability of the entire system. When a battery cell 20 needs to be replaced or repaired, just disconnect the corresponding connecting piece, which is easy to operate and will not affect the operation of other battery cells 20. The connection mode (such as series, parallel or mixed connection) can be adjusted according to actual needs to meet the voltage and current requirements in different application scenarios. The design of the separated positive electrode connecting piece 1131 and the negative electrode connecting piece 1132 helps prevent short circuits and increases the safety of the system. Reasonable arrangement of the connecting pieces can help improve air circulation or coolant flow path, which is beneficial to the thermal management of the entire battery module. The battery cell 20 installation mechanism with battery connecting piece 113 significantly improves the design and application efficiency of the battery module by providing simplified electrical connections, improved reliability and easy maintenance.

[0105] In some embodiments, the battery connector 113 specifically also includes a positive electrode gasket 1133 and a negative electrode gasket 1134. The positive electrode gasket 1133 is arranged on the side of the positive electrode connector 1131 facing the negative electrode connector 1132, and is used to connect the positive electrode of each battery cell 20; the negative electrode gasket 1134 is arranged on the side of the negative electrode connector 1132 facing the positive electrode connector 1131, and is used to connect the negative electrode of each battery cell 20, so that the positive electrode gasket 1133 and the negative electrode gasket 1134 can be used to make the battery cell 20 and the positive electrode connector 1131 and the negative electrode connector 1132 achieve better conductive connection, and reliably connect the positive and negative electrodes of the battery cells 20 in each group.

[0106] In some embodiments, the battery connecting plate 113 specifically also includes a cascade gasket 1135, which is arranged in two adjacent parallel brackets 11, between the positive connecting plate 1131 of one parallel bracket 11 and the negative connecting plate 1132 of the other parallel bracket 11, so as to electrically connect the positive and negative electrodes of two adjacent groups of battery cells 20 to achieve multi-stage series connection.

[0107] In some embodiments, the battery mounting mechanism 10 also includes a positioning plate 12, which is connected to one side of the multiple parallel brackets 11 and extends from one end of the multiple parallel brackets 11 to the other end thereof along the second direction x, and is used to ensure that the parallel brackets 11 and other components maintain a precise positional relationship during the assembly process, thereby improving assembly accuracy and efficiency.

[0108] Further, in some embodiments, each positive electrode bracket 111 and / or each negative electrode bracket 112 is provided with a positioning buckle 1113 protruding toward the third direction z. The positioning buckle 1113 is designed to ensure that the positive electrode bracket 111 and the negative electrode bracket 112 can be accurately aligned during the assembly process to prevent position displacement. The positioning plate 12 is provided with a positioning hole 121 corresponding to each positioning buckle 1113, and each positioning buckle 1113 is embedded in the corresponding positioning hole 121, thereby ensuring that the positioning plate 12 can be firmly fixed on the parallel bracket 11, providing additional mechanical support and precise positioning, and enhancing the structural stability of the entire system, especially under vibration or impact conditions. The cooperation between the positioning buckle 1113 and the positioning hole 121 also ensures the accurate positioning of all components during the assembly process, reduces errors, and improves assembly efficiency and quality.

[0109] In some embodiments, the battery mounting mechanism 10 also includes a circuit board 13, which is connected to the other side of the multiple parallel brackets 11 and extends from one end of the multiple parallel brackets 11 to the other end thereof along the second direction x to cover one side of the entire battery module and provide electrical connection and signal transmission functions.

[0110] Among them, the circuit board 13 is connected to the positive electrode connecting plate 1131 and the negative electrode connecting plate 1132 through pins, welding or other connection methods to ensure that the positive and / or negative electrodes of all battery cells 20 can be effectively connected to the circuit board 13, so that the circuit board 13 can be used to monitor the working status (such as voltage, current, temperature, etc.) of each battery cell 20 in real time, and transmit the data to the external management system through the communication interface.

[0111] In addition, the circuit board 13 may also integrate protection circuits, such as overcurrent protection, short circuit protection and other functions, to improve the safety of the entire system.

[0112] It is understandable that the positioning plate 12 ensures the accurate positioning of all components during the assembly process, reduces errors, and improves assembly efficiency and quality. The design of the circuit board 13 simplifies electrical connections, reduces the complexity and time required for traditional wiring methods, and provides a more reliable connection path. Through the sensors and controllers integrated on the circuit board 13, real-time monitoring and management of the battery module can be achieved, abnormal situations can be discovered and handled in a timely manner, and battery life can be extended. The integrated protection circuit improves the safety of the system and prevents damage or accidents caused by problems such as overcurrent and short circuit. The battery installation mechanism 10 with a positioning plate 12 and a circuit board 13 significantly improves the design and application efficiency of the battery module by providing high-precision assembly, efficient electrical connection, real-time monitoring and management, and enhanced safety.

[0113] In some embodiments, each positive electrode connecting piece 1131 and / or each negative electrode bracket 112 is provided with a first connecting portion 1114 protruding in the opposite direction of the third direction z. The circuit board 13 is provided with a first connecting hole 131 corresponding to each first connecting portion 1114, and each first connecting portion 1114 is embedded in the corresponding first connecting hole 131, thereby ensuring that the circuit board 13 can be tightly connected to the positive electrode connecting piece 1131 and / or the negative electrode bracket 112, providing a reliable electrical connection.

[0114] In some embodiments, each positive electrode bracket 111 and / or each negative electrode bracket 112 is provided with a second connection portion 1124 protruding in the opposite direction of the third direction z. The circuit board 13 is provided with a second connection hole 132 corresponding to each second connection portion 1124, and each second connection portion 1124 is embedded in the corresponding second connection hole 132, thereby further enhancing the connection between the circuit board 13 and the parallel bracket 11, ensuring the reliability and stability of the electrical connection. The design of the first connection portion 1114 and the second connection portion 1124 simplifies the electrical connection, reduces the complexity and time required for the traditional wiring method, and provides a more reliable connection path.

[0115] In some embodiments, the battery mounting mechanism 10 also includes a fan mounting bracket 14, which is connected to one end of multiple parallel brackets 11 to ensure that its position is fixed and stable, and allows the fan to effectively correspond to the heat dissipation gap setting, provide directional airflow, and help heat dissipation.

[0116] When the battery cells 20 are arranged in a plurality of parallel brackets 11 , heat dissipation gaps extending and connected along the second direction x are formed between the battery cells 20 . These heat dissipation gaps provide circulation paths for cooling air, thereby promoting heat dissipation.

[0117] The cooling fan 30 is installed on the fan mounting bracket 14 at a position corresponding to the cooling gap, and can accelerate the air flow by forced convection, effectively remove the heat generated by the battery cell 20, and keep the operating temperature of the battery module within a safe range.

[0118] It is understandable that the design of the heat dissipation gap and the heat dissipation fan 30 significantly enhances the heat dissipation performance of the battery module, helps to maintain the battery cell 20 operating at a suitable operating temperature, prolongs the service life, and improves the system efficiency. The heat dissipation gap extends and connects along the second direction x, ensuring effective heat dissipation even in a compact layout, making full use of limited space. When the heat dissipation fan 30 needs to be cleaned or replaced, just disconnect the fan mounting bracket 14, which is easy to operate and will not affect other parts. The heat dissipation fan 30 can be adjusted according to the actual working environment (such as temperature and humidity) to adapt to different usage conditions. The battery mounting mechanism 10 with the fan mounting bracket 14 significantly improves the design and application efficiency of the battery module by providing efficient heat dissipation performance.

[0119] In some embodiments, the battery mounting mechanism 10 further includes a housing 15, which is an external packaging structure of the entire battery mounting mechanism 10, providing physical protection and environmental isolation. A housing 15 is provided inside the housing for accommodating a plurality of parallel brackets 11 and other components. The plurality of parallel brackets 11 are arranged in the housing cavity, and the height in the first direction y is not greater than the set height, thereby ensuring that the overall size of the battery module meets specific requirements, helping to maintain the compactness of the battery module, adapting to different installation space requirements, and facilitating transportation and installation.

[0120] In some embodiments, the set height may be specifically 37.9 mm, 40 mm, or any other reasonable height not greater than 1U, and this application does not impose any limitation on this.

[0121] It is understandable that the shell 15 provides protection against the external environment, such as dustproof, waterproof, shockproof, etc., which extends the service life of the battery module. The height limit ensures the compactness of the battery module, enabling it to adapt to various installation environments, especially where space is limited. The design of the shell 15 allows the battery module to be installed and disassembled as a whole, which simplifies the installation process and facilitates maintenance and replacement. The shell 15 can be customized according to different usage environments, such as using a higher level of protection in harsh environments. The unified shell 15 design makes the appearance of the battery module more neat and beautiful, while facilitating standardized production and reducing manufacturing costs.

[0122] Different from the prior art, the parallel bracket in the battery mounting mechanism provided by the present application includes a positive pole bracket and a negative pole bracket detachably connected to the positive pole bracket, and two rows of first accommodating holes are arranged at intervals in the first direction on the side of the positive pole bracket facing the negative pole bracket, and a line connecting the center points of two adjacent first accommodating holes in different rows forms a set angle with the first direction to form a first air duct on the parallel bracket, and the set angle is greater than 0; a second accommodating hole is provided on the side of the negative pole bracket facing the positive pole bracket corresponding to each first accommodating hole, and each first accommodating hole and its corresponding second accommodating hole in the parallel bracket are respectively used to set the positive and negative poles of a battery cell, so that each layer of battery cells can be staggered in the first direction, that is, the height direction, with a certain height difference, so as to be more spaced in a limited space. More cells can be arranged closely and the overall height of the product can be effectively reduced, so that it can be applied to any reasonable electronic equipment with limited spatial structure layout, especially server cabinets, power distribution cabinets, communication equipment, etc., with a standard cabinet unit height of 1U, and the application range is wider; and because the negative pole bracket is detachable, it is more convenient to repair or replace a single cell in the battery module; arranging the cells at a certain tilt angle can help improve the cooling effect, reduce mechanical stress or simplify the manufacturing process; non-vertically arranged cells are also conducive to air circulation or heat sink layout, thereby improving the heat dissipation performance of the entire battery module; the detachable design provides the possibility of flexible configuration, and the number and arrangement of cells can be adjusted according to different application requirements.
