[0010] By adopting the above technical solution, the first spring applies elastic force to the push block, and under the push of the push block, the battery pack is subjected to a thrust, thereby achieving the buckling of the buckling piece and the ejection of the battery pack.

[0012] By adopting the above technical solution, the second spring applies a restoring elastic force to the slider. When the fastening piece slides into the fastening groove, the slider can slide and adjust itself as the fastening piece moves, so that the fastening piece can have a corresponding displacement space and finally move to a position where it is fastened with the fastening groove, thereby realizing the fastening action of the fastening piece.

[0014] By adopting the above technical solution, in the process of placing the battery pack into the accommodating groove, the fastening piece can slide into the first inclined section and slide and cooperate with the first inclined section. At this time, the slider is pushed to move to make way, and the second spring is gradually compressed until the fastening block is close to the fastening section. Under the push of the second spring, the slider is reset, and the fastening piece is fastened to the fastening section to achieve mutual fastening with the slider, and the battery pack is fixedly installed.

[0015] Preferably, the reset groove includes a second inclined section and a loose section, one end of the second inclined section is connected to the snap-fit ​​groove, the other end of the second inclined section extends toward the bottom of the accommodating groove and is inclined toward the side away from the second spring, one end of the loose section is connected to one end of the second inclined section away from the snap-fit ​​groove, and the other end of the loose section extends to the side of the notch of the slider toward the accommodating groove and is opened.

[0016] By adopting the above technical solution, when the battery pack needs to be removed from the mounting base, the battery pack is pressed again to move the snap block to the second inclined section.

[0040] Reference Figure 1 and Figure 2 The mounting base 1 includes a base body 11, and the base body 11 is used for mounting the battery pack 2. The base body 11 specifically includes a built-in module 111. In this embodiment, the built-in module 111 is in the shape of a rectangular parallelepiped, and the outer shell 112 is also in the shape of a rectangular parallelepiped. The inner part of the outer shell 112 is hollow and the top is open. The bottom of the outer shell 112 is integrally connected with a plurality of reinforcing ribs 1121 arranged in sequence along the length direction of the outer shell 112. The opening size of the outer shell 112 is larger than the outline size of the built-in module 111.

[0041] The built-in module 111 is fixedly connected to the shell 112, and the built-in module 111 is accommodated in the shell 112. When the built-in module 111 and the shell 112 are fixed to each other, a plurality of plug-in blocks 1111 can be integrally arranged at the periphery of the built-in module 111, and a plurality of slots 1122 adapted to the plug-in blocks 1111 are recessed at the inner side wall of the shell 112. When the built-in module 111 is placed in the shell 112, the bottom of the built-in module 111 abuts against the reinforcing ribs 1121 at the bottom of the shell 112 to form a gap. At the same time, an annular gap is formed between the periphery of the built-in module 111 and the inner wall of the shell 112. The plug-in block 1111 is plugged into the slot 1122 at this time. By fixing the plug-in block 1111 to the shell 112 with screws, the fixed installation of the built-in module 111 can be achieved. The built-in module 111 is detachably connected, which is convenient for later disassembly, replacement and maintenance.

[0042] The mounting base 1 has a plurality of receiving grooves 1112 for the battery pack 2 to be inserted and placed. Specifically, the receiving grooves 1112 are recessed from the outside to the inside and are arranged on the built-in module 111. The openings of the plurality of receiving grooves 1112 are all located on the side surface of the built-in module 111 facing away from the outer shell 112. The number of receiving grooves 1112 can be set accordingly according to actual needs, for example, it can be four, eight or sixteen, etc. The plurality of receiving grooves 1112 are arranged in an array, and the opening contour of the receiving grooves 1112 is adapted to the outer contour of the battery pack 2. The battery pack 2 can be inserted into the receiving grooves 1112. Here, the movement direction of the battery pack 2 inserted into the receiving grooves 1112 is defined as the depth direction of the receiving grooves 1112.

[0043] Reference Figure 3 and Figure 4 In order to improve the stability of the battery pack 2 during installation, the energy storage power supply also includes a pop-up component 4 and an elastic snap-fit ​​component 5, wherein the elastic snap-fit ​​component 5 is movably arranged on the mounting seat 1 and is located on one side of the accommodating groove 1112, the pop-up component 4 is arranged at the bottom of the accommodating groove 1112, and the elastic snap-fit ​​component 5 has a snap-fit ​​groove 511 and a reset groove 512 that are interconnected. The pop-up component 4, the snap-fit ​​groove 511 and the reset groove 512 cooperate with each other to realize the locking and unlocking of the battery pack 2.

[0044] Specifically, the pop-up assembly 4 abuts against the battery pack 2. The pop-up assembly 4 includes a first spring 41 and a push block 42. The outer edge contour of the push block 42 is adapted to the opening contour of the accommodating groove 1112. The push block 42 is inserted into the accommodating groove 1112, and the periphery of the push block 42 slides and abuts against the side wall of the accommodating groove 1112. The push block 42 can slide back and forth along the depth direction of the accommodating groove 1112.

[0045] In addition, the first spring 41 is located between the push block 42 and the bottom of the accommodating groove 1112, one end of the first spring 41 is fixedly installed on the bottom of the accommodating groove 1112, and the other end of the first spring 41 is fixedly connected to the push block 42. After the battery pack 2 is placed into the accommodating groove 1112, the bottom of the battery pack 2 abuts against the push block 42. Then, if the battery pack 2 is pressed into the accommodating groove 1112 until the surface of the battery pack 2 is flush with the surface of the built-in module 111, the first spring 41 is in a compressed state. If the battery pack 2 is released, the first spring 41 can push the push block 42 and pop the battery pack 2 out of the accommodating groove 1112.

[0046] In order to lock and fix the battery pack 2, a buckle 21 is integrally connected to the battery pack 2. The buckle 21 is cylindrical in this embodiment. A recessed groove for the buckle 21 to slide into is provided on the side wall of the receiving groove 1112. The recessed groove extends along the depth of the receiving groove 1112. At the same time, the elastic buckle assembly 5 includes a slider 51 and a second spring 52. The slider 51 is slidably provided on the side wall of the receiving groove 1112. A slide groove is recessed from the outside to the inside at the side wall of the receiving groove 1112. The length direction of the slide groove is perpendicular to the depth direction of the receiving groove 1112. The slider 51 is received in the slide groove and slides against the groove wall of the slide groove. Under the guidance of the slide groove, the moving direction of the slider 51 is perpendicular to the depth direction of the receiving groove 1112.

[0047] In addition, the second spring 52 is accommodated in the slide groove, and the two ends of the second spring 52 are fixedly connected to the slider 51 and the mounting seat 1 respectively. The snap-fit ​​groove 511 and the reset groove 512 are recessed from the outside to the inside and are arranged on one side surface of the slider 51 close to the accommodating groove 1112. The reset groove 512 is closer to the bottom of the accommodating groove 1112 than the snap-fit ​​groove 511.

[0048] Continue to refer to Figure 4Specifically, in order to realize the mutual engagement between the snap-fitting groove 511 and the snap-fitting member 21, the snap-fitting groove 511 includes a first inclined section 5111 and a snap-fitting section 5112. One end of the first inclined section 5111 is opened on the side of the notch of the slider 51 facing the receiving groove 1112, and is directly opposite to the end of the giving way groove extending into the receiving groove 1112. At the same time, the other end of the first inclined section 5111 extends toward the bottom of the receiving groove 1112 and is inclined toward the side away from the second spring 52. The first inclined section 5111 and the snap-fitting member 21 are connected to each other. 21 slides and abuts. In the process of inserting the battery pack 2 into the accommodating groove 1112, the buckle 21 is inserted into the make way groove, and under the guidance of the make way groove, it enters the first inclined section 5111 at one end of the notch of the first inclined section 5111 toward the accommodating groove 1112, and as the buckle 21 continues to move toward the bottom of the accommodating groove 1112, under the guidance of the first inclined section 5111, the buckle 21 pushes the slider 51 to slide, and the slider 51 compresses the second spring 52. At this time, the battery pack 2 is also squeezing the first spring 41 at the same time.

[0049] The length extension direction of the buckling section 5112 is consistent with the moving direction of the slider 51. The buckling section 5112 is located on the side of the first inclined section 5111 close to the second spring 52. One end of the buckling section 5112 is connected to the end of the first inclined section 5111 extending to the middle of the slider 51, and the other end of the buckling section 5112 extends toward the position close to the second spring 52. Here, when the buckling member 21 slides to the end of the first inclined section 5111 close to the buckling section 5112, the second spring 5 The slider 51 is pushed to return to its original position, so that the fastening member 21 slides into the fastening section 5112 until the second spring 52 returns to its natural state; at this time, under the action of the push block 42 and the first spring 41, the groove wall on one side of the fastening section 5112, which is opposite to the notch of the accommodating groove 1112, abuts against the fastening member 21, and the fastening section 5112 and the fastening member 21 are fastened to each other, and the fastening member 21 is fastened to the fastening groove 511, so that the battery pack 2 is fixedly installed, and the first spring 41 remains in a compressed state.

[0050] Continue to refer to Figure 4In order to unlock the battery pack 2, the reset groove 512 includes a second inclined section 5121 and a loose section 5122. One end of the second inclined section 5121 is connected to the end of the buckling section 5112 away from the first inclined section 5111. The second inclined section 5121 is located just in front of the buckling section 5112 along the pressing direction of the battery pack 2. The other end of the second inclined section 5121 extends toward the bottom of the accommodating groove 1112 and is inclined toward the side away from the second spring 52. The battery pack 2 continues to be pressed toward the inside of the accommodating groove 1112, and the first spring 41 further contracts. At the same time, the buckling member 21 moves into the second inclined section 5121, and the buckling member 21 slides and abuts against the groove wall of the second inclined section 5121. Under the guidance of the second inclined section 5121, the buckling member 21 pushes the slider 51 to slide again and compresses the second spring 52, so that the slider 51 gives way to the buckling block.

[0051] In addition, the setting direction of the loosening section 5122 is consistent with the depth direction of the accommodating groove 1112, one end of the loosening section 5122 is connected to the end of the second inclined section 5121 away from the snap-fit ​​groove 511, and the other end of the loosening section 5122 extends to the side of the notch of the slider 51 facing the accommodating groove 1112, and is opened; at this time, the battery pack 2 is released, the first spring 41 applies elastic force to the push block 42, the push block 42 pushes the snap-fitting part 21 in the battery pack 2 out of the loosening section 5122, the snap-fitting part 21 and the slider 51 are loosened from each other, and the battery pack 2 is disassembled, and during this process, the reset groove 512 and the snap-fitting part 21 slide and abut against each other, guiding the snap-fitting part 21 to loosen the elastic snap-fitting component 5.

[0052] Reference Figure 5 In order to realize the output of power supply, the energy storage power supply also includes a conductive component 6, which includes a plurality of wires. The number of wires is matched with the number of accommodating grooves 1112. Access pins 61 and output pins 62 are formed at both ends of the wires. The wires are fixedly installed on the mounting base 1. The output pins 62 of the plurality of wires are connected to the power control system at the same time, and the plurality of access pins 61 extend into the plurality of accommodating grooves 1112 respectively. A through hole communicating with the accommodating groove 1112 can be penetrated on the built-in module 111, and the wires are passed through and penetrated into the accommodating groove 1112.

[0053] In addition, a through hole for passing the wire is opened at the side wall of the control groove so that the pin of the conductive component 6 extends to the side wall of the accommodating groove 1112. There is an interface on the side wall of the battery pack 2. When the fastening piece 21 and the fastening groove 511 are fastened to each other, the interface on the battery pack 2 abuts and cooperates with the access pin 61 of the conductive component 6, thereby realizing the connection between the battery and the power control system, and then realizing the output of power.

[0054] In conventional installation, in order to achieve contact between the battery pack 2 and the access pin 61, the contact point is usually set at the end of the battery pack 2. However, in this solution, the contact of the battery pack 2 cannot be achieved, and there are technical obstacles to the connection of the battery pack 2. Here, the contact point between the battery pack 2 and the access pin 61 is set on the side wall of the accommodating groove 1112, which can well overcome the technical obstacles during connection.

[0055] Furthermore, in order to realize flexible regulation of power, a battery discharge module and a common output module can be set in the power control system. The power discharge module is set to multiple groups, and at least two groups of battery discharge modules are coupled in parallel with the common output module. Each group of power discharge modules includes a switch submodule, a battery input submodule and an automatic identification submodule. The battery input submodule is respectively connected to the output pin 62 of the wire and the common output module. The common output module is connected to the socket, thereby realizing conduction between the battery and the socket.

[0056] The automatic identification submodule is connected to the battery input submodule and the switch submodule respectively. The automatic identification submodule is used to identify whether there is a reverse current. If it is identified that there is a reverse current, a disconnection drive signal is output; if it is identified that there is no reverse current, a conduction drive signal is output; the switch submodule is connected to the battery input submodule. The switch submodule is used to perform an operation of disconnecting the battery input submodule from the common output module based on the received disconnection drive signal, or to perform an operation of connecting the battery input submodule to the common output module based on the received conduction drive signal.

[0057] Among them, if there is a voltage difference between different battery packs 2 connected to different battery discharge modules, the automatic identification submodule corresponding to the battery pack 2 with relatively low voltage controls the switch submodule to disconnect, so that the battery pack 2 is disconnected from the common output module and the power supply is stopped. This protects the battery pack 2 with relatively low voltage and extends the service life of the battery pack 2.

[0058] As for the remaining battery packs 2 with relatively high voltages, their voltages gradually decrease during discharge. When the voltages of the remaining battery packs 2 decrease to the same level as the batteries with relatively low voltages, the automatic identification submodule corresponding to the battery packs 2 with relatively low voltages controls the corresponding switch submodules to turn on, and automatically selects multiple battery packs 2 with consistent voltages to continuously supply power to the electrical products. When the electrical products are not powered off, the battery packs 2 can be switched manually without manual operation, thereby meeting the power supply and endurance requirements of the electrical products and achieving flexible regulation of power.

[0059] Reference Figure 6In order to improve the applicability of the energy storage power supply in different scenarios, the mounting base 1 also includes a cover plate 12, which is rotatably connected to the shell 112 of the base body 11. Usually, the rotatable installation of the cover plate 12 can be achieved by setting a hinge. The size of the cover plate 12 is adapted to the opening size of the shell 112, and the cover plate 12 can be rotatably covered with the opening of the shell 112.

[0060] At the same time, look back Figure 1 The mounting base 1 also includes a locking member 13, which is arranged on the outer shell 112 of the base body 11, and the locking member 13 is located on the side of the mounting base 1 away from the hinge. The locking member 13 is used to fix the cover 12 to the base body 11, thereby improving the stability of the cover 12 when it is closed. The locking member 13 can be made of fasteners such as buckles or spring buckles; when the cover 12 is fixed to the base body 11, the cover 12 covers a plurality of accommodating grooves 1112, and the cover 12 is used to protect the battery pack 2.

[0061] Continue to refer to Figure 6 Here, the gap between the built-in module 111 and the housing 112 is defined as a water-proof cavity 14. The inner wall of the cover plate 12 is respectively fixedly mounted with a first waterproof ring 121 and a second waterproof ring 122. The size of the second waterproof ring 122 is smaller than the size of the first waterproof ring 121. The size of the first waterproof ring 121 is adapted to the outer edge contour size of the housing 112. The size of the second waterproof ring 122 is adapted to the outer edge contour size of the built-in module 111. When the cover plate 12 is covered on the mounting seat 1, the first waterproof ring 1 21 abuts against the periphery of the housing 112, the second waterproof ring 122 abuts against the built-in module 111, and the watertight cavity 14 is located between the first waterproof ring 121 and the second waterproof ring 122. The first waterproof ring 121 and the second waterproof ring 122 have a double-layer waterproof effect, and the waterproof performance of the product under outdoor conditions is improved. At the same time, if the water flow breaks through the first waterproof ring 121, the excess water flow will flow into the watertight cavity 14, reducing the water flow splashing to the second waterproof ring 122, and the waterproof performance of the energy storage power supply is further improved.

[0062] Furthermore, a plurality of drain outlets 1123 are horizontally penetrated through the side wall of the outer shell 112, and a first valve 7 connected to the drain outlet 1123 is fixedly installed on the outer shell 112. The first valve 7 can open and close the first drain outlet 1123. If there is a lot of external water in the water-proof chamber 14, the first valve 7 can be opened to discharge the water. In order to increase the water discharge rate, the first drain outlet 1123 and the first valve 7 can be arranged in multiple groups, such as four groups, eight groups or ten groups, etc. The multiple groups of first drain outlets 1123 and the first valve 7 are evenly arranged along the circumference of the outer shell 112, and the water discharge rate is improved.

[0063] In addition, the cover plate 12 is provided with a heat dissipation hole 123. When the cover plate 12 is covered on the shell 112, the heat dissipation hole 123 is opposite to the water-proof cavity 14, and the heat dissipation hole 123 is connected to the water-proof cavity 14. The cover plate 12 is fixedly installed with a second valve 8 connected to the heat dissipation hole 123. Here, the energy storage power supply is easy to dissipate heat during use, which affects the life of the battery. The heat dissipated by the battery can be added to the air in the water-proof cavity 14. By opening the first valve 7 and the second valve 8, the hot air can be discharged from the heat dissipation hole 123 according to the chimney effect. At the same time, the cold air can be added to the water-proof cavity 14 from the drainage hole to achieve heat dissipation. The process can be repeated. Accordingly, there can be multiple heat dissipation holes 123, and the multiple heat dissipation holes 123 are evenly arranged along the circumference of the water-proof cavity 14. The multiple heat dissipation holes 123 improve the heat dissipation rate of the battery.

[0064] The implementation principle of a portable energy storage power supply capable of achieving capacity expansion in an embodiment of the present application is as follows: if it is necessary to increase the overall capacity of the battery, first insert the battery pack 2 into the accommodating groove 1112. During this process, the fastener 21 slides into the fastening groove 511, and the battery pack 2 abuts against the pop-up component 4. The pop-up component 4 applies an elastic force to the battery pack 2, so that the fastener 21 is fastened to the fastening groove 511, and the battery pack 2 is fixedly installed; when it is necessary to reduce the battery capacity and the overall weight of the battery, press the battery pack 2 again to move the battery pack 2 toward the accommodating groove 1112. At this time, the fastener 21 can enter the reset groove 512, and then the battery pack 2 is released. Under the guidance of the reset groove 512, the fastener 21 loosens the elastic fastening component 5, the battery pack 2 is unlocked, and the capacity of the power supply is conveniently expanded.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
