[0002] The energy storage power supply of the relevant technology includes multiple battery cells, two brackets, a lower shell, a left decorative panel, and a right decorative panel. During assembly, multiple battery cells are fixedly connected by the upper and lower brackets to form a battery module. The battery module is then assembled into the lower shell, and then the left and right decorative panels are assembled into the lower shell or the battery module to form the energy storage power supply. This process involves numerous components and is complex. Utility Model Content

[0003] This application provides an energy storage power source to solve at least one of the aforementioned technical problems.

[0004] The energy storage power source according to the embodiments of this application includes: A first housing, wherein a plurality of first fixing grooves are formed on the inner wall of the first housing; Multiple battery cells, each battery cell having a first end and a second end facing away from each other, the first end being fixed in the first fixing slot; The bracket is fixedly connected to the first housing. The bracket is provided with a plurality of second fixing slots, which are arranged opposite to the first fixing slots. The second end of the battery cell is fixed in the first fixing slot. The bracket is provided with a first side and a second side at both ends along a first direction. The ventilation housing assembly includes a second housing and a third housing disposed opposite to each other, the second housing and the third housing being detachably connected to the first side and the second side, respectively.

[0005] The energy storage power supply provided in this application pre-assembles the bracket, second housing, and third housing into a single unit. During assembly, multiple battery cells only need to be installed inside the first housing, and then the pre-assembled bracket, second housing, and third housing are installed on the first housing. This effectively secures the battery cells, reducing the number of assembly steps and components involved. Furthermore, using the first housing to secure the battery cells saves the need for a lower bracket for fixing the cells, thus improving the space utilization rate of the energy storage power supply.

[0006] In some embodiments, the first housing is a lower housing, and the inner wall is an inner bottom wall.

[0007] In this way, defining the first housing as the lower housing and the inner wall as the inner bottom wall facilitates the assembly and placement of the battery cells, which helps to improve the stability of battery cell installation and the assembly efficiency of energy storage power supply.

[0008] In some embodiments, the second end of the battery cell is provided with a positive electrode and a negative electrode, and the second fixing slot is provided with a clearance hole, through which the positive electrode and the negative electrode are exposed.

[0009] Thus, by using single-sided welding of the battery cell and setting the first end as an empty end and the second end as a tab end, it is beneficial to simplify the battery cell structure and reduce welding complexity, and facilitate the unified connection and management of the tabs in the future.

[0010] In some embodiments, the energy storage power supply further includes an electrical connector disposed on the side of the bracket away from the battery cell, the electrical connector connecting the positive and negative electrodes of adjacent battery cells via the clearance hole.

[0011] In this way, by setting an electrical connector on the side of the bracket away from the battery cell and electrically connecting it to the electrode tab, efficient integration of the battery cell and circuit module is achieved, which facilitates centralized arrangement and maintenance of electrical connections.

[0012] In some embodiments, the energy storage power supply further includes an inverter that is electrically connected to the battery cell.

[0013] In this way, by setting up an inverter that is electrically connected to the battery cell, the function of converting the DC power of the energy storage power supply into AC power is realized, which facilitates the power supply of various AC electrical equipment and expands the application range of the energy storage power supply.

[0014] In some embodiments, the inverter is fixedly mounted on the bracket.

[0015] In this way, by fixing the inverter on the bracket, it is beneficial to make full use of the bracket structure for support and positioning, save internal space, optimize the overall structural layout, and make the electrical connections more centralized and orderly.

[0016] In some embodiments, the bracket is detachably connected to the second and third housings by fasteners.

[0017] Thus, by using fasteners to make the bracket detachably connected to the second and third housings, modular assembly and quick disassembly are achieved, which facilitates later maintenance or replacement of battery cell components.

[0018] In some embodiments, the second housing and the third housing are respectively disposed on opposite sides of the energy storage power source, and ventilation holes are provided on the second housing and the third housing.

[0019] Thus, by setting ventilation holes on the second and third housings, air circulation between the inside and outside of the cavity is achieved, which is beneficial for cell heat dissipation and temperature management, and improves system safety.

[0020] In some embodiments, the energy storage power supply further includes a fourth housing, which is detachably connected to the first housing or the bracket. The first housing, the second housing, the third housing, and the fourth housing enclose a receiving cavity, and the plurality of battery cells and the bracket are all disposed within the receiving cavity.

[0021] Thus, by adding a fourth housing that is detachably connected to the first housing and together forming a receiving cavity, the fully enclosed protection of the battery cell and the bracket is achieved, which helps to improve the overall structure's protectiveness and compactness.

[0022] In some embodiments, the first housing and the fourth housing are connected to form two notches, and the second housing and the third housing are respectively accommodated in the two notches. The peripheral wall of the notch is provided with a slot, and the outer edges of the second housing and the third housing are engaged in the slot to fix the second housing and the third housing to the notch.

[0023] Thus, by setting a notch and slot structure at the connection between the first and fourth housings, the second and third housings can be quickly snapped together and fixed, which helps to simplify the assembly process and enhance the reliability of the housing connection.

[0031] The energy storage power supply of the related technology includes multiple battery cells, two brackets 31, a lower shell, a left decorative panel, and a right decorative panel. During assembly, multiple battery cells are fixedly connected by the upper and lower brackets 31 to form a battery module. The battery module is assembled into the lower shell, and then the left and right decorative panels are assembled into the lower shell or the battery module to form the energy storage power supply. It not only has many parts but also a complex assembly process.

[0032] Please see Figure 1 The energy storage power supply 100 of this application includes a first housing 10, a plurality of battery cells 20, a bracket 31, and a ventilation housing assembly. The inner wall of the first housing 10 forms a plurality of first fixing grooves 11. The battery cell 20 includes a first end 21 and a second end 22 facing away from each other. The first end 21 is fixed in the first fixing groove 11. The bracket 31 is fixedly connected to the first housing 10. The bracket is provided with a plurality of second fixing grooves 311. The second fixing grooves 311 are arranged opposite to the first fixing grooves 11. The second end of the battery cell 20 is fixed in the first fixing groove. The bracket 31 is provided with a first side and a second side at both ends along a first direction. The ventilation housing assembly includes a second housing 32 and a third housing 33 arranged opposite to each other. The second housing 32 and the third housing 33 are detachably connected to the first side and the second side, respectively.

[0033] The energy storage power supply 100 provided in this application pre-assembles the bracket 31, the second housing 32, and the third housing 33 into a single unit. During assembly, multiple battery cells 20 only need to be installed inside the first housing 10, and then the pre-assembled bracket 31, the second housing 32, and the third housing 33 are installed on the first housing 10. This effectively fixes and installs the battery cells 20, reducing the number of assembly steps and components involved in the assembly process. Furthermore, using the first housing 10 to fix the battery cells 20 saves the need for a lower bracket for fixing the battery cells 20, thus improving the space utilization rate of the energy storage power supply 100.

[0034] For details, please refer to Figures 1 to 5 The energy storage power supply 100 is a device that can store electrical energy and release it when needed. Its main function is to provide a stable and reliable power supply. When the system needs to store electrical energy, the controller charges the battery cell 20, which converts the electrical energy into chemical energy for storage. When the system needs to use electrical energy, the controller first converts the DC electrical energy stored in the battery cell 20 into AC electrical energy before outputting it.

[0035] Please see Figure 1 and Figure 4 In this embodiment, the first housing 10 forms an array of first fixing slots 11 in the horizontal direction, with each battery cell 20 corresponding to one slot, thereby achieving a neat arrangement of battery cell groups 20 within the receiving cavity 50. During the specific assembly of the energy storage power supply 100, multiple battery cells 20 are first sequentially placed in the receiving cavity 50 formed by the first housing 10 of the main housing. The first end 21 of the battery cell 20 is embedded in the first fixing slot 11 to achieve preliminary positioning and mechanical limiting, while the second end 22 of the battery cell 20 is positioned upwards.

[0036] Please see Figure 3 and Figure 5 In some embodiments, the bracket 31 is further provided with a second fixing groove 311, the clearance hole 312 is provided at the bottom of the second fixing groove 311, and the second end 22 is fixed in the second fixing groove 311.

[0037] Thus, by setting a second fixing groove 311 in the bracket 31 and placing the clearance hole 312 at its bottom, a double limit is achieved on the second end 22 of the battery cell 20, which is beneficial to enhancing the shock resistance and overall structural stability of the battery cell 20.

[0038] Specifically, in this embodiment, one end of the battery cell 20 is inserted into the first fixing groove 11 and the other end is inserted into the second fixing groove 311. The cooperation of the first fixing groove 11 and the second fixing groove 311 achieves the fixing of the battery cell 20.

[0039] In this embodiment of the application, the battery cell 20 is cylindrical. Correspondingly, the first fixing groove 11 and the second fixing groove 311 should be set as circular grooves that cooperate with the battery cell 20 to ensure the stability of the battery cell 20.

[0040] In some embodiments, the battery cell 20 may also be in the form of a sheet or a block. Correspondingly, the first fixing groove 11 and the second fixing groove 311 should be set as square grooves that cooperate with the battery cell 20 to ensure the stability of the battery cell 20.

[0041] In other examples, the battery cell 20 can also be in other shapes. Correspondingly, the first fixing groove 11 and the second fixing groove 311 should be set as grooves that cooperate with the battery cell 20 to ensure the stable placement of the battery cell 20. No specific restrictions are made here.

[0042] Please see Figure 5 In this embodiment, the first housing 10, the bracket 31, the second housing 32, and the third housing 33 can be made of insulating, heat-resistant, and appropriately rigid plastic materials. When the bracket 31, the second housing 32, and the third housing are installed in place, the second end 22 of the battery cell 20 is inserted into the corresponding second fixing groove 311, thereby limiting and fixing the upper end of the battery cell 20. This, together with the first fixing groove 11 at the bottom, forms a bidirectional constraint on the battery cell 20, which can significantly improve the overall rigidity and vibration resistance of the battery cell 20 assembly.

[0043] In this embodiment, when the second end 22 of the battery cell 20 is inserted into the second fixing slot 311 of the bracket 31, the second housing 32 and the third housing 33 are installed on opposite sides of the battery cell 20 group and connected to the first housing 10. At this time, the first housing 10, the second housing 32, the third housing 33 and the bracket 31 together form a covering structure for the battery cell 20. This can enhance the sealing and protection level of the overall structure, improve assembly efficiency and optimize the utilization of internal space, and is particularly suitable for high energy density energy storage systems with multiple battery cells 20 connected in series and parallel.

[0044] Please see Figures 1 to 3 In some embodiments, the first housing 10 is a lower housing, and the inner wall is an inner bottom wall.

[0045] Thus, defining the first housing 10 as the lower housing and defining the inner wall as the inner bottom wall facilitates the assembly and placement of the battery cell 20, which helps to improve the stability of the battery cell 20 installation and the assembly efficiency of the energy storage power supply 100.

[0046] Specifically, in this embodiment, the first housing 10 is the lower housing, which serves as the basic support for the energy storage power supply 100. Its inner bottom wall provides a stable placement surface for the battery cell 20. The first fixing groove 11 is provided on the inner bottom wall. Due to the flatness of the inner bottom wall, the battery cell 20 can be placed stably, reducing shaking or tilting caused by unstable placement, thereby improving the stability of the battery cell 20 installation. For example, during large-scale assembly on a production line, this stable placement method can greatly improve assembly efficiency and reduce the time required for readjustment due to deviations in the position of the battery cell 20.

[0047] In this embodiment, a support portion is provided on the side of the first housing 10 away from the battery cell 20, and an anti-slip structure is provided on the support portion. Optionally, the anti-slip structure can be an anti-slip silicone pad, an anti-slip rubber pad, or an anti-slip pattern provided on the support portion.

[0048] In other embodiments, a fixing groove may also be provided on the side of the first housing 10 away from the battery cell 20, and a thicker anti-slip pad may be provided in the fixing groove. The material of the anti-slip pad may be selected according to actual needs and is not limited here.

[0049] Please see Figure 1 and Figure 4 In some embodiments, the battery cell 20 is configured with a positive electrode 221 and a negative electrode 222, and the second fixing groove is provided with a clearance hole 312, through which the positive electrode 221 and the negative electrode 222 are exposed.

[0050] Thus, by adopting single-sided welding of the battery cell 20 and setting the first end 21 as an empty end and the second end 22 as a tab end, it is beneficial to simplify the structure of the battery cell 20 and reduce the welding complexity, which facilitates the unified connection and management of the tabs in the future.

[0051] Specifically, the structure of the single-sided welded cell 20 is relatively simple. Compared to the double-sided welded cell 20, it reduces the number of welding points and welding processes, thus lowering the welding complexity. In the production process, fewer welding processes mean a shorter production cycle and lower production costs. For example, in mass production, reducing each welding point saves significant time and labor costs. Furthermore, the single-sided welded cell 20 design also facilitates heat dissipation, as the reduced number of welding points lowers the internal resistance of the cell, reducing heat generation and contributing to improved performance and stability.

[0052] In some embodiments, the energy storage power supply 100 further includes an electrical connector disposed on the side of the bracket 31 away from the battery cell 20. The electrical connector is electrically connected to the positive electrode 221 and negative electrode 222 of the adjacent battery cell 20 via a clearance hole 312.

[0053] Thus, by setting an electrical connector on the side of the bracket 31 away from the battery cell 20 and electrically connecting it to the electrode tab, efficient integration of the battery cell 20 and the circuit module is achieved, facilitating centralized arrangement and maintenance of electrical connections.

[0054] Specifically, in this embodiment, the electrical connector can sequentially and alternately connect the positive terminal 221 and the negative terminal 222 of at least one battery cell 20, so that the positive terminal 221 and the negative terminal 222 connected to the two ends of the electrical connector are positive and negative terminals, respectively. That is, the electrical connector is connected in series with at least one battery cell 20, so that at least one battery cell 20 forms a high-voltage output power supply, thereby ensuring that the user's power demand is met.

[0055] Electrical connectors are sheet metal parts. Sheet metal parts refer to metal products manufactured through specific sheet metal processes. These processes primarily target thin metal sheets (typically below 6mm) and include a series of integrated cold working procedures such as shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. A significant characteristic of sheet metal parts is the consistent thickness of the same component. Sheet metal parts are lightweight, high-strength, have good electrical conductivity (suitable for electromagnetic shielding), low cost, and are suitable for mass production. Sheet metal parts typically possess high tensile and compressive strength, which helps extend the service life of electrical connectors, and their high processing efficiency helps shorten processing cycles.

[0056] In this embodiment of the application, the electrical connector can also be formed by stamping in one step, and the burrs that may occur during the processing are removed, and the sharp corners of the electrical connector are rounded to prevent the electrical connector from injuring the operator's hands during assembly or maintenance.

[0057] In some embodiments, the electrical connectors can be formed by cutting and bending. The specific sheet metal process can be selected according to actual needs and is not limited here.

[0058] In some embodiments, the electrical connectors are made of galvanized sheet.

[0059] Thus, galvanized steel sheets have relatively high strength and durability, which helps to extend the service life of electrical connectors.

[0060] Specifically, galvanized steel sheet refers to steel sheet with a layer of metallic zinc coated on its surface to prevent corrosion and extend its service life.

[0061] It is important to note that before sheet metal processing, the surface of the galvanized sheet must be clean and free of oil, rust, and impurities. These impurities can affect processing accuracy and product quality. Additionally, the galvanized layer should be checked for uniformity and absence of peeling. An uneven galvanized layer can affect the product's corrosion resistance and appearance.

[0062] When galvanized steel sheets are processed into sheet metal, the tool marks produced during the punching process should meet safety requirements (not to cut hands) and part dimensional tolerances, generally not exceeding 10% to 20% of the sheet thickness. The depth of the tool marks produced during the bending process should be controlled within 0.3mm.

[0063] In some embodiments, the energy storage power supply 100 further includes an inverter that is electrically connected to the battery cell 20.

[0064] In this way, by setting up an inverter that is electrically connected to the battery cell 20, the DC power of the energy storage power supply 100 is converted into AC power, which facilitates power supply for various AC electrical devices and expands the applicability of the energy storage power supply 100.

[0065] In this embodiment, the energy storage power supply 100 further includes an inverter, which is disposed in the housing cavity 50 and electrically connected to the battery cell 20 via an electrical connector.

[0066] In some embodiments, the inverter is fixedly mounted on the bracket 31.

[0067] In this way, by fixing the inverter on the bracket 31, it is beneficial to make full use of the structure of the bracket 31 for support and positioning, save internal space, optimize the overall structural layout, and make the electrical connections more centralized and orderly.

[0068] Please see Figure 1 In some embodiments, the bracket 31 is detachably connected to the second housing 32 and the third housing 33 by fasteners.

[0069] Thus, by using fasteners to make the bracket 31 detachably connected to the second housing 32 and the third housing 33, modular assembly and quick disassembly are achieved, which facilitates later maintenance or replacement of the battery cell 20 assembly.

[0070] Specifically, in the embodiments of this application, the bracket 31 is detachably connected to the second housing 32 and the third housing 33 by fasteners, so as to realize the modular assembly and quick disassembly of the bracket 31 to the second housing 32 and the third housing 33.

[0071] In this embodiment, screws can be used as fasteners. In other embodiments, bolts or clips can also be used as fasteners. Specifically, operators can choose appropriate fasteners according to specific needs. For example, if frequent disassembly and assembly of the energy storage power supply 100 is required, a clip connection can be selected, which does not require tools and is convenient and quick to operate. If higher connection strength is required, screws or bolts can be selected, which can provide a more robust connection.

[0072] Please see Figure 1 and Figure 5In some embodiments, the second housing 32 and the third housing 33 are respectively disposed on the left and right decorative panels on opposite sides of the energy storage power supply 100, and ventilation holes 60 are provided on the second housing 32 and the third housing 33.

[0073] Thus, by providing ventilation holes 60 on the second housing 32 and the third housing 33, air circulation is achieved inside and outside the housing 50, which is beneficial for heat dissipation and temperature management of the battery cell 20 and improves system safety.

[0074] Specifically, in this embodiment, the second housing 32 and the third housing 33 are respectively the left and right decorative panels disposed on opposite sides of the energy storage power supply 100, the bracket 31 is disposed between the second housing 32 and the third housing 33, and the second housing 32 and the third housing 33 are respectively connected to the two opposite sides of the first housing 10.

[0075] In this embodiment, ventilation holes 60 are provided on the left and right decorative panels, and a heat dissipation duct is formed in the cavity 50. The heat dissipation duct is connected to the ventilation holes 60, so that air can circulate inside and outside the cavity 50. Furthermore, the energy storage power supply 100 also includes a cooling fan, which is set in the heat dissipation duct to accelerate the air circulation speed in the heat dissipation duct, thereby further improving the heat dissipation efficiency.

[0076] In this embodiment, the left and right decorative panels can be made into louvers to further improve heat dissipation.

[0077] In some embodiments, a dustproof mesh or waterproof cover can be installed at the ventilation hole 60 to prevent dust and moisture from entering the housing cavity 50 and affecting the performance and safety of the battery cell 20. In addition, the design of the ventilation hole 60 can also be coordinated with the overall appearance of the energy storage power supply 100, without affecting the aesthetics of the energy storage power supply 100.

[0078] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, the energy storage power supply 100 further includes a fourth housing 40, which is detachably connected to the first housing 10 or the bracket 31. The first housing 10, the second housing 32, the third housing 33 and the fourth housing 40 enclose a receiving cavity, and multiple battery cells 20 and the bracket 31 are all disposed in the receiving cavity.

[0079] Thus, by adding a fourth housing 40 that is detachably connected to the first housing 10 and together forming a receiving cavity, the fully enclosed protection of the battery cell 20 and the bracket 31 is achieved, which is beneficial to improving the protection and compactness of the overall structure.

[0080] Specifically, in the embodiments of this application, the first housing 10, the second housing 32, the third housing 33 and the fourth housing 40 form the outer shell of the energy storage power supply 100, realizing full-enclosed protection for the battery cell 20 and the bracket 31, and providing higher protection and compactness for the overall structure of the energy storage power supply 100.

[0081] In this embodiment, the first housing 10 and the fourth housing 40 are both integrally formed structures. The fourth housing 40 can be made of the same material as the first housing 10. The fourth housing 40 and the first housing 10 can be detachably connected by screws, buckles or hinges.

[0082] In this embodiment of the application, a handle is provided on the fourth housing 40, which is used for moving and transporting the energy storage power supply 100.

[0083] In some embodiments, the handle is made of metal. Specifically, the handle can be made of aluminum alloy with a hollow interior, which helps to reduce the weight of the energy storage power supply 100. In addition, the aluminum alloy handle has high strength and durability, which helps to increase the reliability of the handle and extend its service life.

[0084] In this embodiment, the energy storage power supply 100 also includes an expansion socket, which is a socket device designed to solve the problem of insufficient number of power sockets. The expansion socket is installed on the left and right side panels.

[0085] In other embodiments, the expansion socket may also be provided on at least one of the first housing 10, the second housing 32, the third housing 33, or the fourth housing 40. The specific configuration can be determined according to actual needs and is not limited here.

[0086] In other embodiments, the two clearance slots may also be provided corresponding to the front and rear side plates respectively.

[0087] In other embodiments, the handle may also be made of other materials, which can be set according to actual needs and are not limited here.

[0088] In other embodiments, the handle may also be configured as a flexible handle, which has good adaptability and flexibility, and provides better comfort and tactile feel.

[0089] Please see Figure 3 and Figure 5 In some embodiments, the first housing 10 includes a plurality of first connecting posts 13, and the second housing 32 includes a plurality of second connecting posts 313. When the first housing 10 is connected to the second housing 32, the first connecting posts 13 are connected to the second connecting posts 313.

[0090] Thus, the first connecting post 13 and the second connecting post 313 are used to connect the first housing 10 and the second housing 32. The first connecting post 13 is beneficial to improving the structural strength of the first housing 10, and the second connecting post 313 is beneficial to improving the structural strength of the second housing 32.

[0091] In some embodiments, the first connecting post 13 is disposed on the inner bottom wall of the first housing 10. Multiple first connecting posts 13 can be arranged in a multi-row, multi-column array, and a first fixing groove 11 is defined between two adjacent rows and two columns of first connecting posts 13. The array arrangement of multiple first connecting posts 13 realizes the interval setting of the first fixing groove 11.

[0092] Similarly, the second connecting post 313 is set on the bracket 31. Multiple second connecting posts 313 can be arranged in a multi-row, multi-column array, and a second fixing slot 311 is defined between two adjacent rows and two columns of second connecting posts 313. The array arrangement of multiple first connecting posts 13 realizes the placement of the first fixing slot 11 at intervals.

[0093] Furthermore, the first connecting post 13 and the first housing 10 are integrally formed, and the second connecting post 313 and the fourth housing 40 are integrally formed.

[0094] In other embodiments, the first fixing groove 11 and the second fixing groove 311 may also be other shapes, such as rectangles, to ensure that the battery cells 20 of different shapes are placed stably. No specific restrictions are made here.

[0095] In some embodiments, due to the relatively long lengths of the first connecting post 13 and the second connecting post 313, a first reinforcing rib 14 is further provided on the first housing 10 to enhance its structural strength. The first reinforcing rib 14 is triangular or trapezoidal, with one end connected to the inner bottom wall and the other end connected to the first connecting post 13. Similarly, a second reinforcing rib 314 is also provided on the bracket 31. The second reinforcing rib 314 is triangular or trapezoidal, with one end connected to the bracket 31 and the other end connected to the second connecting post 313.

[0096] Furthermore, each first connecting post 13 is connected to a plurality of first reinforcing ribs 14, and similarly, each second connecting post 313 is connected to a plurality of second reinforcing ribs 314. In this embodiment of the application, each first connecting post 13 is connected to at least three first reinforcing ribs 14, and similarly, each second connecting post 313 is connected to at least three second reinforcing ribs 314.

[0097] Furthermore, to further enhance the structural strength of the first connecting post 13, the first reinforcing rib 14 between two adjacent first connecting posts 13 located on the outside of the battery cell 20 is connected. Similarly, the second reinforcing rib 314 between two adjacent second connecting posts 313 located on the outside of the battery cell 20 is also connected.

[0098] In some embodiments, the energy storage power supply 100 further includes a plurality of fasteners, which are respectively fastened to the corresponding first connecting post 13 and second connecting post 313, so that the first housing 10 is connected to the bracket 31.

[0099] Thus, using fasteners to achieve a detachable connection between the first connecting post 13 and the second connecting post 313 helps to reduce the maintenance difficulty of the energy storage power supply 100.

[0100] Specifically, in this embodiment, the first connecting post 13 on the first housing 10 extends toward the bracket 31 along the height direction of the energy storage power supply 100, and the second connecting post 313 on the bracket 31 extends toward the first housing 10 along the height direction of the energy storage power supply 100. Both the first connecting post 13 and the second connecting post 313 are hollow inside and have threaded holes at their opposite ends. The interior of the second connecting post 313 is provided with fasteners that can be screwed into the threaded holes, and the first connecting post 13 and the second connecting post 313 are detachably connected through threaded connection.

[0101] In other embodiments, fasteners that can be screwed into threaded holes may also be disposed inside the first connecting post 13.

[0102] In other embodiments, the first connecting post 13 and the second connecting post 313 can also be detachably connected by means of snap-fit, pin, etc.

[0103] Please see Figure 3 and Figure 6 In some embodiments, after the first housing 10 and the fourth housing 40 are connected, two notches are formed. The second housing 32 and the third housing 33 are respectively accommodated in the two notches. The peripheral wall of the notch is provided with a slot. The outer edges of the second housing 32 and the third housing 33 are engaged in the slot to fix the second housing 32 and the third housing 33 in the notch.

[0104] Thus, by setting a notch and a slot structure at the connection between the first housing 10 and the fourth housing 40, the second housing 32 and the third housing 33 can be quickly snapped together and fixed, which helps to simplify the assembly process and enhance the reliability of the housing connection.

[0105] Specifically, the notch may include a first notch 12 and a second notch 41. The first notch 12 is located in the first housing 10, and the second notch 41 is located in the fourth housing 40. The first housing 10 and the fourth housing 40 are connected so that the first notch 12 and the second notch 41 are connected to form a notch. Taking the second housing 32 as an example, a part of the second housing 32 is accommodated in the first notch 12 on the side wall of the first housing 10, and another part of the second housing 32 is accommodated in the second notch 41 on the side wall of the fourth housing 40. The peripheral wall of the notch is provided with a groove, and the outer edge of the second housing 32 is adapted to the groove, so that the outer edge of the second housing 32 or the third housing 33 can be engaged in the groove, so that the second housing 32 or the third housing 33 is fixed to the notch, thereby fixing the second housing 32 or the third housing 33 to the first housing 10 and the fourth housing 40.

[0106] Optionally, the shapes of the first notch 12 and the second notch 41 are adapted to the shapes of the second housing 32 and the third housing 33, so that the second housing 32 and the third housing 33 can be smoothly embedded in the notches and fit tightly against the sidewalls of the first housing 10 and the fourth housing 40.
