Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, specifically to a modular mobile energy storage module that is easy to stack and store. Background Technology

[0002] A portable power bank is a device that can store electrical energy and provide a stable power output. It typically consists of a storage battery and a power conversion and control unit. The storage battery in a portable power bank generally uses a high-energy-density lithium-ion battery or a lithium polymer battery, which can store a large amount of electrical energy and has a long service life. Furthermore, the lithium-ion battery in a portable power bank converts chemical energy into electrical energy, and its characteristics include high efficiency, cleanliness, environmental friendliness, and reusability, making it a promising choice for a wide range of applications.

[0003] For example, patent document CN222620718U discloses a split-type energy storage mobile power supply device. In use, the main unit is assembled onto the power supply unit, and charging is then achieved through a connection area. By incorporating a splitting device and a foot pedal assembly, when the main unit and power supply unit need to be separated, rotating the pedal to be perpendicular to the moving frame causes a positioning block to press against the moving frame. The user then steps on the pedal, which moves a guide rod and a ball within the positioning post. Once spring one is in motion to its designated position, the guide rod and ball lose their restraint on the pressing block. Spring two then moves a limiting rod and the pressing block back to their original positions, allowing the limiting rod to be pulled out of the inner wall of the insertion block. The user can then remove the main unit by lifting their hands upwards for disassembly. This splitting device facilitates quick and stable disassembly of the split-type energy storage mobile power supply device through hand-foot coordination, demonstrating significant advantages in practical applications and greatly simplifying the disassembly of the main unit and power supply unit. However, existing technologies generally employ a step-by-step operation mode of "connecting power first and then fixing" or "fixing first and then connecting power": when connecting power first and then fixing, the pulling of the power supply body during the fixing process can easily lead to loosening of the interface and poor contact; when fixing first and then connecting power, the fixing structure may restrict the alignment of the interface, increasing the difficulty of docking. At the same time, most solutions only use single-sided or single-structure fixing, which has weak anti-tipping ability and is prone to displacement of stacked units in vibration environments (such as vehicle transportation). Summary of the Invention

[0004] The purpose of this invention is to provide a modular mobile energy storage module that is easy to stack and store, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular mobile energy storage module that is easy to stack and store, comprising a main body and a docking support assembly. The docking support assembly is installed on the side of the main body. The docking support assembly includes a vertical arm that limits rotation on the side of the main body. A rotating ring is coaxially fixed at the top of the vertical arm, and a busbar is fixedly installed in the inner opening of the vertical arm. The cross-section of the busbar is convex. A locking hole is opened at the bottom of the busbar, and bushings are embedded at equal intervals at the top of the busbar. A telescopic current collector rod slides axially inside the bushing through a spring.

[0006] Furthermore, a synchronous drive assembly is installed inside the vertical arm. The synchronous drive assembly includes an isolation cavity located in the gap between the busbar and the side wall of the vertical arm. A rotating shaft is rotatably installed inside the isolation cavity, and the axis of the rotating shaft is parallel to the Z-axis direction of the busbar.

[0007] Furthermore, the synchronous drive assembly also includes a knob coaxially fixed to the top of the rotating shaft, and cams are axially and equally spaced at the middle of the rotating shaft, with the outer edge of the cams tightly fitted to the tail pin of the telescopic current collector.

[0008] Furthermore, the synchronous drive assembly also includes a support block coaxially fixed to the bottom end of the rotating shaft. The support block is rotatably mounted on the outside of the bottom end of the vertical arm, and the length of the support block is consistent with that of the vertical arm.

[0009] Furthermore, a trunnion is fixedly installed on the side of the main body, and a button is axially slidably installed outside the trunnion via a spring. A limit block is symmetrically fixed at the tail end of the button, and the limit block is matched with the groove at the corresponding position of the inner ring of the rotating ring.

[0010] Furthermore, several power supply units are stacked and installed below the main body, and the adjacent power supply units are of the same specifications. The bottom of each power supply unit is fixed with protruding feet around its perimeter, and the top of each power supply unit is provided with grooves around its perimeter. The protruding feet and grooves of the adjacent power supply units are inserted into each other.

[0011] Furthermore, positioning frames are fixedly installed on both sides of the power supply body, and the size of the positioning frame cavity matches the shape of the vertical arm. An electrical connection window is opened on the inner side of the positioning frame cavity, and the electrical connection window is electrically connected to the corresponding telescopic current collector rod in contact.

[0012] Furthermore, a sliding adapter assembly is installed between the two vertical arms. The sliding adapter assembly includes a crossbeam that is slidably installed between the two vertical arms. A male connector is installed at the middle end of the crossbeam and is electrically connected to the female connector at the bottom of the main body.

[0013] Furthermore, the sliding adapter also includes notches at both ends of the crossbeam. The crossbeam engages with the convex structure of the adjacent side busbar through the notches at both ends, and the crossbeam is connected to the corresponding power source through the telescopic current collector on the busbar.

[0014] Furthermore, the sliding adapter also includes a second knob rotatably mounted in the middle of the crossbeam. The second knob has a gear coaxially connected inside, and the two ends of the gear are meshed with a rack. The rack is slidably mounted on a track, and the track is fixedly mounted inside the crossbeam cavity. The end of the rack is fixedly connected with a locking pin, and the locking pin is inserted into a locking hole on the corresponding side busbar.

[0015] This invention provides a modular mobile energy storage module that is easy to stack and store, and has the following advantages; 1. In use, the current of all power sources is connected to the busbar through the telescopic collector rod at the power connection window of each power source. The current of all power sources is collected through the busbar to the crossbeam, which serves as the top-level adapter plate, and then connected to the main interface of the main body, forming a complete parallel circuit of single power source → telescopic collector rod → busbar → crossbeam adapter plate → main body. There are no current conflict points. Through the coaxial design of the cam and the support block, when the shaft is rotated into place, the cam pushes the telescopic collector rod to insert into the power connection window on the side of the power source. At the same time, the support block unfolds synchronously, forming a linkage logic that is stable upon power connection. This avoids the loosening of the interface caused by power connection in an unfixed state. The busbar is built into the hanging arm, which can prevent dust and accidental contact, reducing the risk of short circuit. At the same time, after installation on both sides, a dual-path parallel conduction is formed. Even if the contact on one side fails, the other side can still ensure power supply, improving circuit redundancy.

[0016] 2. When this application is in use, during the insertion of the vertical arm along the positioning frames on both sides of the stacked power supply body, the power supply body pushes the crossbeam to slide and rise along the vertical arm through physical contact. During this process, the crossbeam is guided and constrained by both sides of the vertical arm and can only move in the vertical direction until the male plug is automatically inserted into the female plug interface. There is no need for the user to manually adjust the position of the crossbeam, realizing the blind operation effect of insertion and docking. The entire electrical connection process relies on the forced guidance and limitation of the mechanical structure. The user does not need to look down to observe the interface position. The docking can be completed by simply judging the insertion depth of the vertical arm and the sliding state of the crossbeam by touch, which significantly improves the operation efficiency.

[0017] 3. The U-shaped frame in this device, consisting of two hanging arms and a crossbeam connecting them, has a dual practical function. Normally, when the user needs to move the main unit, the U-shaped frame is flipped upwards and used as a handle. When in use, the U-shaped frame serves another function: connecting the power supply unit. At this time, the interior of the U-shaped frame becomes the key area for connecting the power supply unit. The internal dimensions of the U-shaped frame are cleverly designed, not only precisely matching the external dimensions of the power supply unit, but also allowing the hanging arms to penetrate all the positioning frames on the sides of the stacked power supply units during insertion, thus fixing the stacked units as a whole from the side, improving anti-tipping ability, and achieving a stable connection between the main unit and the power supply unit.

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Please see Figures 4 to 5This invention provides a technical solution: a modular mobile energy storage module that is easy to stack and store, including a main body 1 and a docking support component 2. The docking support component 2 is installed on the side of the main body 1. The docking support component 2 includes a hanging arm 201 that limits rotation at the side of the main body 1. A rotating ring 202 is coaxially fixed at the top of the hanging arm 201. A busbar 203 is fixedly installed in the inner opening of the hanging arm 201. The cross-section of the busbar 203 is convex. A lock hole 204 is opened at the bottom of the busbar 203. A bushing 205 is embedded at equal intervals at the top of the busbar 203. A telescopic current collector 206 slides axially inside the bushing 205 through a spring. A trunnion 4 is fixedly installed on the side of the main body 1. A button 5 is axially slidable outside the trunnion 4 through a spring. A limit block 6 is symmetrically fixed at the tail end of the button 5. The limit block 6 is limited and engaged with the groove at the corresponding position of the inner ring of the rotating ring 202. The specific operation is as follows: During the flipping process of the vertical arm 201 located at the trunnion 4 on the side of the main body 1 via the rotating ring 202, the limiting block 6 symmetrically fixed at the tail end of the button 5 and the corresponding groove of the inner ring of the rotating ring 202 are used to ensure that the position of the male plug 1202 of the crossbeam 1201 after flipping accurately corresponds to the position of the female plug interface at the bottom of the main body 1, avoiding interface misalignment caused by the flipping angle deviation, and laying the foundation for blind operation. At this time, during the insertion of the vertical arm 201 along the positioning frames 10 on both sides of the stacked power supply body 7, the power supply body 7 is physically connected... The touch pushes the crossbeam 1201 to slide and lift along the vertical arm 201. During this process, the crossbeam 1201 is guided and constrained by both sides of the vertical arm 201 and can only move in the vertical direction until the male plug 1202 is automatically inserted into the female plug interface. The user does not need to manually adjust the position of the crossbeam 1201, achieving a blind operation effect of insertion and docking. The entire electrical connection process relies on the forced guidance and limit of the mechanical structure. The user does not need to look down to observe the interface position. The docking can be completed by simply judging the insertion depth of the vertical arm 201 and the sliding state of the crossbeam 1201 by touch, which significantly improves the operation efficiency. Please see Figures 6 to 7 The drooping arm 201 is equipped with a synchronous drive assembly 3. The synchronous drive assembly 3 includes an isolation cavity 301 located in the gap between the busbar 203 and the side wall of the drooping arm 201. A rotating shaft 302 is rotatably installed inside the isolation cavity 301, and the axis of the rotating shaft 302 is parallel to the Z-axis direction of the busbar 203. The synchronous drive assembly 3 also includes a knob 303 coaxially fixed to the top of the rotating shaft 302. Cams 304 are axially and equally spaced at the middle end of the rotating shaft 302, and the outer edge of the cams 304 is tightly fitted with the tail pin of the telescopic current collector 206. The synchronous drive assembly 3 also includes a support block 305 coaxially fixed to the bottom end of the rotating shaft 302. The support block 305 is rotatably installed outside the bottom end of the drooping arm 201, and the length of the support block 305 is the same as that of the drooping arm 201. The specific operation is as follows: After the power supply unit 7 is installed in place, rotate the knob 303 on the side of the vertical arm 201 and drive the rotating shaft 302 to rotate. The rotating shaft 302 has a cam 304 and a support block 305 coaxially integrated. Rotating the knob 303 can simultaneously achieve two actions: First, when the rotating shaft 302 rotates, it drives the bottom support block 305 to rotate around the axis, changing from a folded state to a horizontal support, further enhancing the stability of the device in the stacked state; Second, when the cam 304 rotates with the rotating shaft 302, its eccentric contour squeezes the tail pin of the telescopic current collector 206, thereby causing the telescopic current collector 206 to extend out of the bushing 205 embedded in the busbar 203 and insert into the power connection window 11 on the side of the power supply unit 7 in a straight line. After the power connection window 11 on each power supply unit 7 is connected to the busbar 203 through the telescopic current collector 206, all power supply units 7 The current is collected through the busbar 203 and fed to the crossbeam 1201, which serves as the top-level adapter plate, and then connected to the main interface of the main body 1, forming a complete parallel circuit of single power supply body 7 → telescopic collector rod 206 → busbar 203 → crossbeam 1201 adapter plate → main body 1, with no current conflict points. This application uses the coaxial design of cam 304 and support block 305. When the rotating shaft 302 is rotated into place, cam 304 pushes telescopic collector rod 206 to insert into the power connection window 11 on the side of power supply body 7. At the same time, support block 305 unfolds synchronously, forming a linkage logic that is stable upon power connection, avoiding interface loosening caused by power connection in an unfixed state. The busbar 203 is built into the hanging arm 201, which can prevent dust and accidental contact, reducing the risk of short circuit. At the same time, after installation on both sides, a dual-path parallel conduction is formed. Even if the contact on one side fails, the other side can still ensure power supply, improving circuit redundancy. Please see Figures 1 to 7Several power supply units 7 are stacked below the main body 1, with adjacent power supply units 7 having the same specifications. Each power supply unit 7 has protruding feet 8 fixed around its bottom edge and recesses 9 around its top edge. The protruding feet 8 and recesses 9 of adjacent power supply units 7 are inserted into each other. Positioning frames 10 are fixedly installed on both sides of the power supply unit 7, and the cavity size of the positioning frame 10 matches the shape of the vertical arm 201. A power connection window 11 is opened inside the cavity of the positioning frame 10, and the power connection window 11 is electrically connected to the corresponding telescopic current collector rod 206. A sliding adapter assembly 12 is installed between the two vertical arms 201. The sliding adapter assembly 12 includes a crossbeam 1201 slidably installed between the two vertical arms 201. A male connector 1202 is installed in the middle of the crossbeam 1201, and the male connector 1202 is electrically connected to the female connector at the bottom of the main body 1. The adapter assembly 12 also includes recesses 1203 at both ends of the crossbeam 1201. The crossbeam 1201 is engaged with the "convex" structure of the adjacent side busbar 203 through the recesses 1203 at both ends. The crossbeam 1201 is connected to the corresponding power source 7 through the telescopic current collector rod 206 on the busbar 203. The sliding adapter assembly 12 also includes a knob 1204 rotatably installed in the middle of the crossbeam 1201. A gear 1205 is coaxially connected inside the knob 1204. A rack 1206 is meshed at both ends of the gear 1205. The rack 1206 is slidably installed on the track 1207. The track 1207 is fixedly installed inside the cavity of the crossbeam 1201. A locking pin 1208 is fixedly connected to the end of the rack 1206. The locking pin 1208 is inserted into the locking hole 204 on the corresponding side busbar 203. The specific operation is as follows: The U-shaped frame in this device, composed of two hanging arms 201 and a crossbeam 1201 connecting them, has a dual practical function. Normally, when the user needs to move the main body 1, the U-shaped frame is flipped upwards to serve as a handle. At this time, the locking pins 1208 at both ends of the crossbeam 1201 are inserted into the locking holes 204 on the corresponding side busbars 203 to lock the position, making it convenient for the user to hold the crossbeam 1201 and lift the main body 1 for movement. When in use, the U-shaped frame also serves as a connection to the power supply 7. In this case, the user needs to rotate the knob 1204. Gear 1205, and then under the meshing action of gear 1205 and the toothed rods 1206 at both ends, drives the locking pins 1208 on both sides to exit the locking hole 204 simultaneously. Then, press button 5 and flip the U-shaped frame downwards. At this time, the inside of the U-shaped frame becomes the key area for connecting the power supply body 7. The internal dimensions of the U-shaped frame are cleverly designed. Not only are the dimensions precisely matched with the external dimensions of the power supply body 7, but the vertical arm 201 can penetrate through the positioning frames 10 on the sides of all stacked power supply bodies 7 during insertion, fixing the stacked units as a whole from the side, improving the anti-tipping ability, and realizing a stable connection between the main body 1 and the power supply body 7.

[0021] In summary, when using this modular mobile energy storage module that is easy to stack and store: Firstly, the U-shaped frame in this device, composed of two hanging arms 201 and a crossbeam 1201 connecting them, has a dual practical function. Normally, when the user needs to move the main body 1, the U-shaped frame is flipped upwards to serve as a handle. At this time, the locking pins 1208 at both ends of the crossbeam 1201 are inserted into the locking holes 204 on the corresponding side busbars 203 to lock the position, making it convenient for the user to hold the crossbeam 1201 and lift the main body 1 for movement. When in use, the U-shaped frame also serves as a connection to the power supply 7. In this case, the user needs to rotate the gear using knob 1204. 1205, and then under the meshing action of gear 1205 and the toothed rods 1206 at both ends, the locking pins 1208 on both sides are driven to exit the locking hole 204 simultaneously. Then, press button 5 and flip the U-shaped frame downwards. At this time, the inside of the U-shaped frame becomes the key area for connecting the power supply body 7. The internal dimensions of the U-shaped frame are cleverly designed. Not only are the dimensions precisely matched with the external dimensions of the power supply body 7, but the vertical arm 201 can penetrate through the positioning frame 10 on the side of all stacked power supply bodies 7 during insertion, fixing the stacked unit as a whole from the side, improving the anti-tipping ability, and realizing a stable connection between the main body 1 and the power supply body 7. Secondly, during the flipping process of the vertical arm 201 located on the side trunnion 4 of the main body 1 via the rotating ring 202, the limiting block 6 symmetrically fixed at the tail end of the button 5 and the corresponding groove of the inner ring of the rotating ring 202 ensure that the position of the male plug 1202 of the crossbeam 1201 accurately corresponds to the position of the female plug interface at the bottom of the main body 1 after flipping, avoiding interface misalignment caused by the flipping angle deviation, and laying the foundation for blind operation. At this time, during the insertion of the vertical arm 201 along the positioning frames 10 on both sides of the stacked power supply body 7, the power supply body 7 is pushed by physical contact. The moving crossbeam 1201 slides and rises along the vertical arm 201. During this process, the crossbeam 1201 is guided and constrained by both sides of the vertical arm 201 and can only move in the vertical direction until the male plug 1202 is automatically inserted into the female plug interface. The user does not need to manually adjust the position of the crossbeam 1201, achieving a blind operation effect of insertion and docking. The entire electrical connection process relies on the forced guidance and limit of the mechanical structure. The user does not need to look down to observe the interface position. The docking can be completed by simply judging the insertion depth of the vertical arm 201 and the sliding state of the crossbeam 1201 by touch, which significantly improves the operation efficiency. Finally, after the power supply unit 7 is installed in place, rotate the knob 303 on the side of the vertical arm 201 to rotate the shaft 302. The shaft 302 has a cam 304 and a support block 305 coaxially integrated. Rotating the knob 303 can simultaneously achieve two actions: First, when the shaft 302 rotates, it drives the bottom support block 305 to rotate around the shaft, changing from a folded state to a horizontal support, further enhancing the stability of the device in the stacked state; Second, when the cam 304 rotates with the shaft 302, its eccentric contour presses against the tail pin of the telescopic current collector 206, causing the telescopic current collector 206 to extend out of the bushing 205 embedded in the busbar 203 and insert into the power connection window 11 on the side of the power supply unit 7 in a straight line. After the power connection window 11 on each power supply unit 7 is connected to the busbar 203 through the telescopic current collector 206, the power of all power supply units 7 is connected. The current flows through the busbar 203 to the crossbeam 1201, which serves as the top-level adapter plate, and then connects to the main interface of the main body 1, forming a complete parallel circuit of single power supply body 7 → telescopic collector rod 206 → busbar 203 → crossbeam 1201 adapter plate → main body 1. There are no current conflict points. This application uses the coaxial design of cam 304 and support block 305. When the rotating shaft 302 is rotated into place, cam 304 pushes telescopic collector rod 206 to insert into the power connection window 11 on the side of power supply body 7. At the same time, support block 305 unfolds synchronously, forming a linkage logic that is stable upon power connection. This avoids the interface loosening caused by power connection in an unfixed state. The busbar 203 is built into the hanging arm 201, which can prevent dust and accidental contact, reducing the risk of short circuit. At the same time, after installation on both sides, a dual-path parallel conduction is formed. Even if the contact on one side fails, the other side can still ensure power supply, improving circuit redundancy.
