[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] Please refer to Figure 1 and Figure 2 The energy storage battery box includes a tray 1, a back plate 2, and a protective cover 3. The battery module is placed in the tray 1. The female connector end 4 is fixedly mounted on the side wall of the tray 1 and electrically connected to the battery module. The male connector end 5 and the electronic components are both mounted on the back plate 2. The two opposite sides of the protective cover 3 are respectively bent and extended to form a flip edge 31. The two opposite sides of the back plate 2 are respectively formed with a card slot 21. The flip edge 31 is fixed in the card slot 21 so that the protective cover 3 can be plugged into the back plate 2 in a pluggable manner and form a whole with the back plate 2. The back panel 2 is mounted on the tray 1 via a suspension mechanism 6, which passes through the back panel 2 and the side walls of the tray 1 to fix the back panel 2 on the tray 1. Therefore, by forming a separation mode between the back panel 2 and the tray 1 and then creating a detachable connection with the tray 1 via the suspension mechanism 6, when removing the battery module, the suspension mechanism 6 is first removed, and the back panel 2 and the protective cover 3 are removed at the same time. After installing the replaced battery module, the back panel 2 and the protective cover 3 are installed together on the tray 1 without disassembling connectors and other electronic components. This structure is easy to disassemble and assemble, saves time and effort, and is highly efficient.

[0025] It is worth mentioning that the tray 1 is square in shape and is made of welded steel plates, and its two opposite side plates are hollow structures to reduce the overall weight of the tray 1.

[0026] like Figure 2 and Figure 3As shown, specifically, in this embodiment, the hanging mechanism 6 includes a hanging rod 61 and a stop ring 63. The end of the hanging rod 61 is provided with a non-return hook 611. One end of the hanging rod 61 with the non-return hook 611 passes through the back plate 2 and the side wall of the tray 1. The non-return hook 611 is stopped on the inner side surface of the tray 1. The stop ring 63 is axially mounted on the hanging rod 61 and is located on the side surface of the back plate 2. A through hole is formed on the side wall of the tray 1 close to the back plate 2. The back plate 2 also has a through hole. After the end of the hanging rod 61 with the non-return hook 611 is inserted into the through hole, it is rotated 90 degrees counterclockwise or clockwise so that the non-return hook 611 hooks the inner wall surface of the side wall of the tray 1. Finally, the stop ring 63 is fixed to position the hanging rod 61.

[0027] See also Figure 3 Furthermore, the hanging rod 61 is L-shaped. The non-return hook 611 and the rod body of the hanging rod 61 form an L-shaped whole, wherein the hanging rod 61 is formed by bending.

[0028] Furthermore, the end of the suspension rod 61 and the stop ring 63 are connected by threads. Specifically, the end of the suspension rod 61 away from the non-return hook 611 is threaded, and the stop ring 63 is a nut. The nut is screwed on the screw to fix it on the back plate 2.

[0029] The backplane 2 is made of steel plate. A battery energy network card, NBMU, fan, and connector male end 5 are provided on the backplane 2. The backplane 2 and tray 1 are separated. The backplane 2 is detachably fixed to the tray 1 through the suspension mechanism 6. The connector female end 4 is installed on the tray 1. The connector integrates the acquisition interface and the power interface. The power interface connects the positive and negative poles of the battery module, and the acquisition interface connects the temperature and voltage acquisition harness of the battery module. This type of electrical connection scheme for electronic devices can achieve electrical connection with the battery module even when the backplane is separated. The card slot 21 is integrally formed with the backplane 2. The card slot 21 is formed by bending the side of the backplane 2. Specifically, the card slot 21 is U-shaped. The interior of the U-shaped slot has a certain installation space so that the flip edge can be inserted into the card slot 21. In this way, the protective cover 3 can be connected to the backplane 2 as a whole, and installation and removal are more convenient. When replacing the battery module, simply remove the suspension mechanism 6 and take off the back plate 2. After installing the new battery, install the back plate 2 and the protective cover 3 together on the side wall of the tray 1 through the suspension mechanism 6.

[0030] It should be noted that in this embodiment, the slot 21 and the flip edge 31 are formed by an interference fit. Of course, in another preferred embodiment, a baffle is further provided at the bottom of the slot 21, and the flip edge 31 is supported on the baffle. The baffle is installed at the bottom of the slot 21. When the protective cover 3 is inserted into the back plate 2, the baffle further secures the protective cover 3 to prevent it from falling.

[0031] like Figure 2 As shown, as another preferred embodiment of this embodiment, in order to make the female and male ends of the connector smoother when inserted and connected, a guide sleeve 7 is further installed on the outer periphery of the female end 4 of the connector, and a guide insert ring 8 is installed on the outer periphery of the male end 5 of the connector. When the male end 5 of the connector is assembled with the female end 4 of the connector, the guide insert ring 8 is inserted into the guide sleeve 7. Therefore, when the male end of the connector is inserted into the female end, the guide sleeve 7 and the guide insert ring 8 can play a guiding role, thereby improving the installation and connection speed.

[0032] Specifically, the protective cover 3 effectively isolates the electronic components on the back panel 2. Made of a transparent material, the protective cover 3 clearly displays the electronic components mounted on the back panel 2 and the connection status of the connector male end 5. Preferably, the protective cover 3 is made of acrylic. Acrylic is an insulating material and provides a certain safety benefit. It is worth noting that, since a fan is installed on the back panel 2 to cool the batteries, several ventilation holes are provided on the protective cover 3 at positions corresponding to the fan.

[0033] Please refer to Figure 4 and Figure 5 The present invention also provides a battery box rack, comprising the above-mentioned battery box, a support frame 10, a plurality of brackets 20 and a support plate 30 mounted on the support frame 10, wherein the tray 1 of the battery box is supported on the support plate 30 and is detachably mounted on the bracket 20. Multiple battery boxes can be placed on the support frame 10 to improve the convenience of large energy storage requirements.

[0034] Furthermore, two opposite sides of the tray 1 are connected to a positioning edge 11, and a limiting groove 201 is provided on the bracket 20. The positioning edge 11 is inserted into the limiting groove 201 to form a detachable connection between the tray 1 and the tray 1. In this way, the number of battery boxes installed on the battery rack can be flexibly changed according to the energy storage requirements, which is more convenient to use.

[0035] The energy storage battery box and battery box rack provided by the embodiment of the present invention are configured such that the back plate 2 and the tray 1 are separated and then detachably connected to the tray 1 through a suspension mechanism 6. When disassembling the battery module, the suspension mechanism 6 is first removed, and the back plate 2 and the protective cover 3 are removed at the same time. After installing the replaced battery module, the back plate 2 and the protective cover 3 are installed together on the tray 1 without the need to disassemble the connector and other electronic components. This structure is easy to assemble and disassemble, saves time and effort, and is highly efficient.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
