[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A stackable modular household energy storage device, such as Figure 1-6 As shown, it includes a mounting plate 100, a push plate 110 is fixedly mounted on one side of the upper end of the mounting plate 100, two groups of first limit plates 120 are mounted on both sides of the upper end of the mounting plate 100, multiple groups of power module bodies 130 are arranged between each group of first limit plates 120, a self-clamping limit assembly 140 is arranged at a position where one end of the first limit plate 120 contacts the surface of the power module body 130, and an expansion assembly 150 is arranged on the outer walls of both ends of the push plate 110;

[0027] The self-clamping limit assembly 140 includes a moving block 141 slidably installed in the side wall cavities of the two groups of first limit plates 120, and each group of moving blocks 141 is penetrated by a positioning rod 142 fixed to the inner end of the side wall cavity of the first limit plate 120. The outer wall of the positioning rod 142 is sleeved with a first telescopic spring 143, and one end of the first telescopic spring 143 is fixed to the inner end of the cavity of the first limit plate 120. A travel block 144 is fixedly installed on one side of the upper end of the moving block 141, and a travel groove 149 is opened on the side wall of the travel block 144. A connecting plate 145 is slidably provided on the inner wall of the travel groove 149, and a pushing block 146 extending from the outside of the first limit plate 120 is installed on the other end of the connecting plate 145. A limiting block 147 at a position in contact with the surface of the connecting plate 145 is fixedly installed on the side wall of the first limit plate 120, and a power wiring block 148 is fixedly installed on the upper end of the power module body 130.

[0028] When multiple groups of power module bodies 130 are quickly installed and stacked, the power module bodies 130 are first slid and placed on the moving block 141 set at the bottom. After being blocked by the long plate fixedly installed between the two groups of first limit plates 120 at one end of the installation plate 100, the pushing action on the power module body 130 is released, so that the power module body 130 falls to the moving block 141. At this time, the moving block 141 is affected by the gravity of the power module body 130, which prompts the moving block 141 to move downward, and at the same time, the travel block 144 fixedly installed at the upper end is driven to slide in the travel groove 149 provided at one end of the travel block 144 when the travel block 144 moves downward synchronously. The connecting plate 145 moves outwardly to cause the pushing block 146 installed at one end of the connecting plate 145 to clamp and fix the side wall of the power module body 130 slidably placed on the upper end of the moving block 141, thereby facilitating the installation work between the power module bodies 130, so that the power wiring blocks 148 installed between each group of power module bodies 130 can be positioned, installed and stacked. When disassembling, the topmost power module body 130 is disassembled first, and then the two groups of power wiring blocks 148 below are lifted and pulled outward in turn, so that the placed power module bodies 130 can be self-clamped and fixed, saving the installation time between multiple groups of power module bodies 130, and indirectly improving the efficiency of installation and disassembly.

[0029] Please refer to Figure 5 and Figure 6 The unfolding assembly 150 includes two groups of L-shaped blocks 151 rotatably mounted on the outer wall of the first limiting plate 120, two groups of toggle rods 152 are rotatably mounted on the outer wall of the first limiting plate 120 at positions contacting the surfaces of the L-shaped blocks 151, a second limiting plate 153 is fixedly mounted on the outer wall of the first limiting plate 120 at positions contacting the surfaces of the toggle rods 152, a fixing rod 154 close to one side of the second limiting plate 153 is fixedly mounted on one end of the first limiting plate 120, and the outer side of the fixing rod 154 is fixedly mounted on the outer wall of the first limiting plate 120. A tension spring 155 fixed to the end of the toggle rod 152 is fixedly installed on the wall, a circular rod 156 is rotatably installed on the side wall of the toggle rod 152, a fixing plate 157 is fixedly installed on the rear end of the L-shaped block 151, a telescopic circular guide rod 158 is rotatably installed on one end of the fixing plate 157, a sliding block 159 is rotatably installed on the other end of the telescopic circular guide rod 158, a sliding rod 1591 is installed inside the sliding block 159, and a second telescopic spring is sleeved on the outer wall of the sliding rod 1591.

[0030] When stabilizing the multiple groups of power module bodies 130 installed on the upper end of the mounting plate 100, the figure shows the storage state. After the Vientiane self-locking wheel is locked, one end of the toggle rod 152 is rotated to install the circular rod 156 and pull it downward, so that the toggle rod 152 is tilted at an angle, so that the two groups of symmetrically arranged toggle rods 152 lose the blocking and limiting position of the L-shaped block 151. The second telescopic spring sleeved on the outer wall of the sliding block 159 can cause the telescopic circular guide rod 158 to maintain a certain inclination angle with the L-shaped block 151, so that the L-shaped block 151 is elastically expanded and contacts the ground, avoiding free contact of the L-shaped block 151. By increasing the contact area between the two sides of the mounting plate 100 and the ground, the mounting plate 100 is stably supported to avoid the mounting plate 100 being hit and tipping over, thereby causing damage to the power module body 130.

[0031] Please refer to Figure 1 and Figure 2 A plurality of slide grooves are provided on a side of the side wall of the first limiting plate 120 close to the power module body 130 , and the shape of the slide grooves matches the moving block 141 .

[0032] After the power module body 130 slides between the two sets of first limiting plates 120 and is placed on the upper end of the moving block 141 , the gravity of the power module body 130 causes the moving block 141 to move downward along the slide groove.

[0033] Please refer to Figure 3 and Figure 4 One end of the limiting block 147 is provided with a through groove at a position in contact with the surface of the connecting plate 145 , and the size of the through groove is consistent with the size of the connecting plate 145 .

[0034] When the limiting block 147 moves downward, it causes the connecting plate 145 to slide horizontally along the through groove provided inside the limiting block 147 , thereby limiting the movement of the connecting plate 145 .

[0035] Please refer to Figure 4 A wiring block is fixedly installed at the bottom end of the power module body 130 at a position in contact with the surface of the power wiring block 148.

[0036] The multiple groups of power wiring blocks 148 are connected through the provided power wiring blocks 148 and the plug-in blocks, so as to complete the stacking of the multiple groups of power module bodies 130 .

[0037] Please refer to Figure 1 Two sets of handles are rotatably installed at one end of the push plate 110, and the outer wall of each set of handles is sleeved with a non-slip rubber sleeve. Four sets of universal self-locking wheels are installed at the bottom end of the mounting plate 100, and each set of universal self-locking wheels is fixed to the bottom end of the mounting plate 100 by bolts.

[0038] When the mounting plate 100 is pushed as a whole, after holding the handle, the push plate 110 and the mounting plate 100 can be pushed and moved.

[0039] When in use, when multiple groups of power module bodies 130 are quickly installed and stacked, the power module bodies 130 are first slid and placed on the moving block 141 set at the bottom. After being blocked by the long plate fixedly installed between the two groups of first limit plates 120 at one end of the mounting plate 100, the pushing action on the power module body 130 is released, so that the power module body 130 falls to the moving block 141. At this time, the moving block 141 is affected by the gravity of the power module body 130, prompting the moving block 141 to move downward, and at the same time, the travel block 141 fixedly installed at the upper end is moved downward. 4. When the travel block 144 moves downward synchronously, the connecting plate 145 slidingly arranged in the travel groove 149 at one end of the travel block 144 is driven to move outward, so that the pushing block 146 installed at one end of the connecting plate 145 clamps and fixes the side wall of the power module body 130 slidingly placed on the upper end of the moving block 141, which facilitates the installation work between the power module bodies 130, so that the power wiring blocks 148 installed between each group of power module bodies 130 are installed and stacked in a positioned manner. When disassembling, the topmost power module body 130 is disassembled first, and then the topmost power module body 130 is disassembled according to the arrangement. The two groups of power wiring blocks 148 at the bottom are lifted and pulled outwards, so that the placed power module main body 130 can be self-clamped and fixed, which saves the installation time between multiple groups of power module main bodies 130, and improves the efficiency of installation and removal in disguise. When the multiple groups of power module main bodies 130 installed on the upper end of the mounting plate 100 are stabilized, the figure shows the storage state. After the universal self-locking wheel is locked, one end of the toggle rod 152 is rotated to install the circular rod 156 and pull it downward, so that the toggle rod 152 is tilted at an angle, so that the two groups of symmetrically arranged toggle rods 152 lose the alignment with L The blocking limit of the L-shaped block 151 and the second telescopic spring sleeved on the outer wall of the sliding block 159 can cause the telescopic circular guide rod 158 to maintain a certain inclination angle with the L-shaped block 151, so that the L-shaped block 151 can be elastically expanded and contacted with the ground, avoiding free contact of the L-shaped block 151, and by increasing the contact area between the two sides of the mounting plate 100 and the ground, the mounting plate 100 is stably supported to avoid the mounting plate 100 being hit and tipped over, thereby causing damage to the power module main body 130. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
