[0001] This invention belongs to the field of energy storage power supply technology, and specifically relates to an energy storage power supply module. Background Technology

[0002] Currently, energy storage power supplies are generally integrated energy storage power supplies. The so-called integrated vehicle-mounted energy storage power supply adopts the form of an integrated energy storage power supply cabinet. Due to the capacity requirements of vehicle-mounted power supplies, the weight of the energy storage power supply cabinet is generally 1 to 2 tons. This type of vehicle-mounted energy storage power supply is extremely difficult to install, disassemble, and maintain. Moreover, once a problem occurs, it is often necessary to disassemble and repair the entire energy storage power supply cabinet, which involves a very large amount of work.

[0003] Therefore, it is necessary to invent an energy storage power module to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an energy storage power module to solve the issues raised in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An energy storage power module includes multiple parallel energy storage units placed side-by-side inside a module frame. A cover plate is provided on the top of the module frame, with fastening components securing the four corners of the cover plate to the top of the module frame. Protective components are provided at two notches in the module frame. Each protective component includes a baffle, a screw, a mounting bracket, a crossbar, and a movable part. Two baffles are provided at the notches in the module frame. The screw spirally penetrates the top of the baffle, and the mounting bracket is located inside the baffle. When multiple energy storage units are placed correspondingly inside the module frame, the mounting bracket is positioned between the energy storage units and the baffles. The inner end of the screw is inserted into the outer end of the mounting bracket, and the inner end of the screw is aligned with the end face of the energy storage unit. The inner end of the mounting bracket is sleeved onto the surface of the crossbar. The center of the crossbar connects to the bottom of the movable part, and the movable part vertically penetrates the cover plate.

[0007] Furthermore, two bottom grooves are provided on the side of the module frame, and the two bottom grooves correspond one-to-one with two baffles. An inner rod is embedded inside the bottom groove, and an insert rod is fixed to the bottom of the inner side of the baffle. The insert rod is inserted into the bottom groove, and the inner end of the insert rod is sleeved on the surface of the inner rod.

[0008] Furthermore, a round tube is fixed to the inner end of the mounting bracket, and the end of the crossbar is inserted into the round tube. The horizontally moving baffle uses a screw to drive the mounting bracket to move on the surface of the crossbar.

[0009] Furthermore, when the horizontally moving baffle uses a screw to detach the mounting bracket from the crossbar, the moving parts cause the crossbar to move upward.

[0010] Furthermore, the movable component includes: a vertical rod, an elastic element, a bottom ring, and a bottom rod; the top end of the vertical rod passes through the cover plate, the bottom end of the vertical rod is fixed with a bottom ring, and the bottom ring is correspondingly sleeved at the center of the horizontal rod; an elastic element is sleeved on the surface of the vertical rod, the bottom end of the elastic element is connected to the top of the bottom ring, the top end of the elastic element is connected to the bottom surface of the cover plate, the top end of the bottom rod spirally passes through the bottom of the bottom ring, and the surface of the horizontal rod is provided with an insertion hole, the top end of the bottom rod is inserted into the insertion hole.

[0011] Furthermore, two opposing fixing rods are fixed to the surface of the vertical rod, and a stop bar is fixed to the outer end of the fixing rod. Multiple tooth grooves are opened on the bottom surface of the outer end of the stop bar, and multiple teeth are provided on the outer end of the bracket, and the teeth mesh with the tooth grooves.

[0012] Furthermore, the fastening assembly includes: two arc-shaped plates and a threaded sleeve; the two arc-shaped plates are arranged opposite each other, and the bottom end of the arc-shaped plates is fixed to the top surface of the cover plate. A support rod is fixed to the top surface of the module frame, the support rod vertically penetrates the cover plate, and the support rod is located between the two arc-shaped plates. The concave surface of the arc-shaped plates fits against the outer circumferential surface of the support rod. The threaded sleeve is rotatably sleeved on the outside of the two arc-shaped plates, and the threaded sleeve is spirally sleeved on the outside of the support rod.

[0013] Furthermore, multiple bottom sleeves are fixed to the bottom surface of the cover plate, and the multiple bottom sleeves correspond one-to-one with multiple support rods. The fastening assembly ensures that when the cover plate is fixed to the top of the module frame, the bottom surface of the bottom sleeves fits into the top surface of the module frame.

[0014] Furthermore, the bottom of the cover plate is provided with multiple support bars, each with a socket at both ends. The top surface of the energy storage unit is fixed with two connecting ends, which are inserted into the sockets of the support bars. The top of the cover plate is fixed with multiple connectors, each corresponding to one of the support bars. Two adjacent energy storage units are electrically connected using the connectors.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention uses a fastening component to move the cover plate up until the socket of the rack strip is separated from the connection end, which facilitates the replacement of the damaged energy storage unit and the placement of the new energy storage unit inside the module frame. The fastening component is then used to move the cover plate down until the socket of the rack strip is fitted onto the top of the connection end, thus completing the rapid replacement of the energy storage unit.

[0017] 2. In this invention, the inner end of the screw is squeezed by the screw, and the baffle squeezes multiple energy storage units on the inner side of the module frame through the bracket and the movable parts.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] This invention provides an energy storage power module, such as Figures 1 to 8As shown, the module includes multiple parallel energy storage units 1, which are configured as energy storage power sources. The multiple energy storage units 1 are placed side by side inside the module frame 2. The top of the module frame 2 is provided with a cover plate 3. The four corners of the cover plate 3 are all installed on the top of the module frame 2 using fastening components. The two notches of the module frame 2 are provided with protective components. The protective components include: baffles 4, screws 5, mounting brackets 6, crossbars 7, and movable parts. Two baffles 4 are provided at the notches of the module frame 2. The screws 5 spirally penetrate the top of the baffles 4, and the mounting brackets 6 are located inside the baffles 4. When the multiple energy storage units 1 are placed inside the module frame 2, the mounting brackets 6 are located between the energy storage units 1 and the baffles 4. The inner end of the screws 5 is inserted into the outer end of the mounting brackets 6, and the inner end of the screws 5 is aligned with the end face of the energy storage units 1. The inner end of the mounting brackets 6 is sleeved on the surface of the crossbar 7. The center of the crossbar 7 is connected to the bottom of the movable part, and the movable part vertically penetrates the cover plate 3. The bottom of the cover plate 3 is provided with multiple support strips 19, each with a socket at both ends. Two connection ends 20 are fixed to the top surface of the energy storage unit 1, and these connection ends 20 are inserted into the sockets of the support strips 19. Multiple connectors 21 are fixed to the top of the cover plate 3, and each connector 21 corresponds one-to-one with a support strip 19. Two adjacent energy storage units 1 are electrically connected using connectors 21. When the cover plate 3 is placed on top of multiple energy storage units 1, the connection ends 20 of the tops of two energy storage units 1 are inserted into the sockets of a single support strip 19. Connectors 21 are installed on top of the cover plate 3, and each connector 21 contains a built-in wire. The top of the connection end 20 of the energy storage unit 1 is connected to the connector 21. At this time, two adjacent energy storage units 1 are electrically connected using connectors 21.

[0029] Multiple energy storage units 1 are arranged side by side inside the module frame 2. A cover plate 3 is placed on top of the module frame 2. The bottom surface of the cover plate 3 corresponds to the top of the connecting end 20 through the insertion of the frame bar 19. The connector 21 is fixed to the top surface of the cover plate 3. When the cover plate 3 is fixed to the top of the module frame 2 using the fastening components, two adjacent energy storage units 1 are connected by the connector 21. The cover plate 3 locks the connecting end 20 on the top of the energy storage unit 1 through the insertion of the frame bar 19 to prevent the energy storage unit 1 from shifting inside the module frame 2.

[0030] exist Figures 1 to 4In this design, a round tube 10 is fixed to the inner end of the mounting bracket 6, and the end of the crossbar 7 is inserted into the round tube 10. The horizontally moving baffle 4 uses a screw 5 to drive the mounting bracket 6 to move on the surface of the crossbar 7, and the center of the baffle 4 is connected to the cylinder output end. The movable parts include: a vertical rod 11, an elastic element 12, a bottom ring 13, and a bottom rod 14. The elastic element 12 is set as a spring. The top end of the vertical rod 11 passes through the cover plate 3, and the bottom end of the vertical rod 11 is fixed with a bottom ring 13, which is correspondingly sleeved at the center of the crossbar 7. The surface of the vertical rod 11 is sleeved with the elastic element 12, the bottom end of the elastic element 12 is connected to the top of the bottom ring 13, and the top end of the elastic element 12 is connected to the bottom surface of the cover plate 3. The top end of the bottom rod 14 spirally passes through the bottom of the bottom ring 13, and the surface of the crossbar 7 is provided with an insertion hole. The top end of the bottom rod 14 is inserted into the insertion hole, and the bottom rod 14 prevents the crossbar 7 from rotating and moving inside the bottom ring 13. When the horizontal bar 7 is pulled down, the lowered horizontal bar 7 uses the bottom ring 13 to pull the vertical bar 11 down. The vertical bar 11 moves down at the bottom of the cover plate 3, and the lowered bottom ring 13 cooperates with the elastic element 12 to pull down until the end of the horizontal bar 7 corresponds to the round tube 10. The round tube 10 is sleeved on the end of the horizontal bar 7 by horizontal movement. At this time, the baffle 4 cooperates with the screw 5 to facilitate the attachment frame 6 to pull the horizontal bar 7.

[0031] Two opposing fixing rods 111 are fixed to the surface of the vertical rod 11. A stop bar 112 is fixed to the outer end of the fixing rod 111. Multiple tooth grooves 113 are opened on the bottom surface of the outer end of the stop bar 112. Multiple teeth 601 are provided on the outer end of the bracket 6, and the teeth 601 mesh with the tooth grooves 113. After the cover plate 3 is installed, the cylinder is started. The cylinder output causes the baffle 4 to move horizontally. The moving baffle 4 gradually approaches the vertical rod 11 until the teeth 601 on the outer end of the rotating frame 6 contact the outer end of the baffle 112. Since the vertical rod 11 is connected to the baffle 112 by the fixed rod 111, the baffle 112 is limited by the teeth 601, which causes the mounting bracket 6 to rotate on the inner end surface of the screw 5. The rotating mounting bracket 6 causes the teeth 601 to enter the tooth groove 113 until the rotating mounting bracket 6 is in a horizontal state. The baffle 4 continues to move inward, causing the mounting bracket 6 to move on the bottom surface of the baffle 112, and the outer end of the teeth 601 of the mounting bracket 6 contacts the bottom surface of the baffle 112.

[0032] At this time, the crossbar 7 is pulled down, causing the movable part to move down until the end of the crossbar 7 corresponds to the mounting bracket 6. The moving baffle 4 uses the screw 5 to drive the mounting bracket 6 closer to the crossbar 7. At this time, the round tube 10 on the inner end of the mounting bracket 6 is gradually sleeved on the end of the crossbar 7. The baffle 4 limits the mounting bracket 6 through the screw 5. The baffle 4 and the energy storage unit 1 limit the mounting bracket 6, and the horizontally set crossbar 7 uses the round tube 10 to keep the mounting bracket 6 in a horizontal state.

[0033] After both baffles 4 are secured to the mounting brackets 6 by screws 5, the mounting brackets 6 are then connected to the ends of the crossbars 7 by round tubes 10. The baffles 4 secure the crossbars 7 by the mounting brackets 6, facilitating the pulling of the movable parts by the crossbars 7. At this time, the movable parts protect the top of the energy storage unit 1, and the two baffles 4 protect the bottom of the energy storage unit 1, preventing external parts from directly impacting the energy storage unit 1. Tightening the screws 5 causes the inner end of the screws 5 to press against the energy storage unit 1, and the baffles 4, through the mounting brackets 6 and the movable parts, press against multiple energy storage units 1 on the inner side of the module frame 2. The module frame 2 uses two protective components to clamp the energy storage units 1. The module frame 2, the two protective components, and the multiple energy storage units 1 form an integrated unit, preventing the energy storage units 1 from shifting due to external impacts and avoiding bending of the connecting end 20 due to movement of the energy storage units 1.

[0034] exist Figure 1 , Figure 2 and Figures 6 to 8 In this module frame 2, two bottom grooves are provided on the side, each corresponding to one of the two baffles 4. An inner rod 8 is embedded inside the bottom groove. A plug rod 9 is fixed to the bottom of the inner side of each baffle 4, inserted into the bottom groove, with its inner end sleeved on the surface of the inner rod 8. When the baffle 4 is pushed horizontally, its inner side fits against the side of the module frame 2. The moving baffle 4 moves within the bottom groove using the plug rod 9, which slides on the surface of the inner rod 8. The inner rod 8 limits the plug rod 9, preventing the baffle 4 from detaching from the module frame 2.

[0035] The cylinder output end causes the baffle 4 to move away from the vertical rod 11, and the mounting bracket 6 moves on the bottom surface of the baffle 112. When the horizontally moving baffle 4 uses the screw 5 to cause the mounting bracket 6 to disengage from the horizontal rod 7, the movable part causes the horizontal rod 7 to move upward. When the baffle 4 moves away from the movable part, the moving baffle 4 slides on the surface of the inner rod 8 using the insert rod 9, and the baffle 4 pulls the mounting bracket 6 horizontally through the screw 5. The mounting bracket 6 slides on the surface of the horizontal rod 7 using the round tube 10. When the round tube 10 separates from the horizontal rod 7, the mounting bracket 6 slides on the bottom surface of the baffle 112 until the teeth 601 of the mounting bracket 6 correspond to the tooth groove 113. The outer end of the mounting bracket 6, which continues to move outward, rotates on the inner end surface of the screw 5 until the round tube 10 is vertically downward. At this time, the movable part pulls the horizontal rod 7 upward.

[0036] The outward movement of the baffle 4 aligns the inner end of the screw 5 with the outermost energy storage unit 1, and the mounting bracket 6 is in a vertical position. The cover plate 3 is moved upward by the fastening assembly. The upward-moving cover plate 3 drives the crossbar 7 to move upward synchronously with the moving parts until the insertion port of the rack 19 separates from the connecting end 20. The cover plate 3 stops moving upward. At this time, the energy storage unit 1 is pushed to move inside the module frame 2 until the energy storage unit 1 separates from the module frame 2, making it easy to replace the damaged energy storage unit 1. The new energy storage unit 1 is then placed back inside the module frame 2. The cover plate 3 is moved downward by the fastening assembly until the insertion port of the rack 19 is fitted onto the top of the connecting end 20, completing the quick replacement of the energy storage unit 1.

[0037] exist Figure 1 , Figures 5 to 7 In this assembly, the fastening components include two arc-shaped plates 15 and a threaded sleeve 16. The two arc-shaped plates 15 are arranged opposite each other, with the bottom ends of the arc-shaped plates 15 fixed to the top surface of the cover plate 3. A support rod 17 is fixed to the top surface of the module frame 2, vertically penetrating the cover plate 3 and positioned between the two arc-shaped plates 15. The concave surface of the arc-shaped plates 15 is in contact with the outer circumferential surface of the support rod 17. The threaded sleeve 16 is rotatably sleeved on the outside of the two arc-shaped plates 15 and screwed onto the outside of the support rod 17. When the threaded sleeve 16 is turned, since the cover plate 3 uses the two arc-shaped plates 15 to limit the threaded sleeve 16, the rotating threaded sleeve 16 rotates on the surface of the support rod 17. The rotating threaded sleeve 16 uses the two arc-shaped plates 15 to drive the cover plate 3 to move up and down.

[0038] Multiple bottom sleeves 18, made of rubber, are fixed to the bottom surface of the cover plate 3. Each bottom sleeve 18 corresponds to a support rod 17. The fastening assembly ensures that when the cover plate 3 is fixed to the top of the module frame 2, the bottom surface of the bottom sleeve 18 is in contact with the top surface of the module frame 2. When the cover plate 3 moves down until the bottom surface of the bottom sleeve 18 is in contact with the top surface of the module frame 2, the connecting end 20 of the energy storage unit 1 is inserted into the socket of the frame bar 19. Continue to tighten the screw sleeve 16. The moving cover plate 3 and the module frame 2 cooperate to press the bottom sleeve 18 until the top of the connecting end 20 contacts the connector 21. Stop turning the screw sleeve 16. At this time, the multiple energy storage units 1 form an integrated power module using the multiple connectors 21.

[0039] Working principle of this invention:

[0040] Reference Figures 1 to 8 As shown, multiple energy storage units 1 are arranged side-by-side inside the module frame 2. A cover plate 3 is placed on top of the module frame 2, with the bottom surface of the cover plate 3 corresponding to the top of the connecting end 20 via the insertion port of the support bar 19. Tightening the screw sleeve 16 causes it to rotate on the surface of the support rod 17, as the cover plate 3 uses two arc-shaped plates 15 to constrain the screw sleeve 16. The rotating screw sleeve 16, through the two arc-shaped plates 15, drives the cover plate 3 to move up and down.

[0041] When the cover plate 3 moves down until the bottom surface of the bottom sleeve 18 is in contact with the top surface of the module frame 2, the connecting end 20 of the energy storage unit 1 is inserted into the socket of the frame bar 19. Continue to tighten the screw sleeve 16, and the moving cover plate 3 and the module frame 2 cooperate to press the bottom sleeve 18 until the top of the connecting end 20 contacts the connector 21. Stop rotating the screw sleeve 16. At this time, multiple energy storage units 1 form an integrated power module using multiple connectors 21.

[0042] After the cover plate 3 is installed, the cylinder is started. The cylinder output causes the baffle 4 to move horizontally. The moving baffle 4 gradually approaches the vertical rod 11 until the teeth 601 on the outer end of the rotating frame 6 contact the outer end of the baffle 112. Since the vertical rod 11 is connected to the baffle 112 by the fixed rod 111, the baffle 112 is limited by the teeth 601, which causes the mounting bracket 6 to rotate on the inner end surface of the screw 5. The rotating mounting bracket 6 causes the teeth 601 to enter the tooth groove 113 until the rotating mounting bracket 6 is in a horizontal state. The baffle 4 continues to move inward, causing the mounting bracket 6 to move on the bottom surface of the baffle 112, and the outer end of the teeth 601 of the mounting bracket 6 contacts the bottom surface of the baffle 112. Pull the crossbar 7 down, and the crossbar 7 will cause the movable part to move down until the end of the crossbar 7 corresponds to the inner end of the round tube 10. The inwardly moving baffle 4 uses the screw 5 to drive the sticker 6 to approach the crossbar 7. At this time, the round tube 10 at the inner end of the sticker 6 is gradually sleeved on the end of the crossbar 7. Then, the round tube 10 at the inner end of another sticker 6 is sleeved on the other end of the crossbar 7, and the tension applied to the crossbar 7 is released.

[0043] After both baffles 4 are secured to the mounting brackets 6 by screws 5, the mounting brackets 6 are then connected to the ends of the crossbars 7 by round tubes 10. The baffles 4 secure the crossbars 7 by the mounting brackets 6, facilitating the pulling of the movable parts by the crossbars 7. At this time, the movable parts protect the top of the energy storage unit 1, and the two baffles 4 protect the bottom of the energy storage unit 1, preventing external parts from directly impacting the energy storage unit 1. Tightening the screws 5 causes the inner end of the screws 5 to press against the energy storage unit 1, and the baffles 4, through the mounting brackets 6 and the movable parts, press against multiple energy storage units 1 on the inner side of the module frame 2. The module frame 2 uses two protective components to clamp the energy storage units 1. The module frame 2, the two protective components, and the multiple energy storage units 1 form an integrated unit, preventing the energy storage units 1 from shifting due to external impacts and avoiding bending of the connecting end 20 due to movement of the energy storage units 1.

[0044] The cylinder output end causes the baffle 4 to move away from the vertical rod 11, and the mounting bracket 6 moves on the bottom surface of the baffle 112. When the horizontally moving baffle 4 uses the screw 5 to cause the mounting bracket 6 to disengage from the horizontal rod 7, the movable part causes the horizontal rod 7 to move upward. When the baffle 4 moves away from the movable part, the moving baffle 4 slides on the surface of the inner rod 8 using the insert rod 9, and the baffle 4 pulls the mounting bracket 6 horizontally through the screw 5. The mounting bracket 6 slides on the surface of the horizontal rod 7 using the round tube 10. When the round tube 10 separates from the horizontal rod 7, the mounting bracket 6 slides on the bottom surface of the baffle 112 until the teeth 601 of the mounting bracket 6 correspond to the tooth groove 113. The outer end of the mounting bracket 6, which continues to move outward, rotates on the inner end surface of the screw 5 until the round tube 10 is vertically downward. At this time, the movable part pulls the horizontal rod 7 upward.

[0045] The outward movement of the baffle 4 aligns the inner end of the screw 5 with the outermost energy storage unit 1, and the mounting bracket 6 is in a vertical position. The cover plate 3 is moved upward by the fastening assembly. The upward-moving cover plate 3 drives the crossbar 7 to move upward synchronously with the moving parts until the insertion port of the rack 19 separates from the connecting end 20. The cover plate 3 stops moving upward. At this time, the energy storage unit 1 is pushed to move inside the module frame 2 until the energy storage unit 1 separates from the module frame 2, making it easy to replace the damaged energy storage unit 1. The new energy storage unit 1 is then placed back inside the module frame 2. The cover plate 3 is moved downward by the fastening assembly until the insertion port of the rack 19 is fitted onto the top of the connecting end 20, completing the quick replacement of the energy storage unit 1.

[0046] When the inner end of the bracket 6, the round tube 10, is always fitted onto the surface of the crossbar 7, the cover plate 3 moves upward through the fastening assembly. The upward-moving cover plate 3 moves onto the surface of the vertical bar 11, and pulls on the elastic element 12 on the surface of the vertical bar 11. The extended elastic element 12 improves the buffering effect of the entire moving part, preventing the impact force of external components from being applied to the energy storage unit 1 through the moving part. The cover plate 3 moves downward through the fastening assembly, locking the connection end 20 at the top of the energy storage unit 1 through the insertion port of the bracket 19. This prevents the energy storage unit 1 from shifting inside the module frame 2, improving the stability of the energy storage unit 1 inside the module frame 2, and preventing the entire power module from failing to supply power due to the shifting of the energy storage unit 1.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
