The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] The present disclosure provides a battery energy storage box for a battery, comprising a box body, a handle and a clamping assembly, the box body having a containing cavity, the containing cavity being used to accommodate a battery module, the handle being connected to the box body, the box body being provided with a first avoiding hole, the handle being movably arranged in the first avoiding hole, each of the clamping assemblies comprising a transmission member, a clamping member and an elastic member, the transmission member being respectively connected to the handle and the clamping member, one end of the elastic member being connected to the clamping member, the other end of the elastic member being movably connected to the inner wall of the box body, the box body being provided with a sliding channel, at least a part of the clamping member being slidably arranged through the sliding channel, and an end of the clamping member away from the transmission member being used for clamping with a clamping position of an electrical device.

[0033] In the battery energy storage box for the above-mentioned battery, the handle is movably arranged in the first avoidance hole, the transmission member is respectively connected to the handle and the clamping member, one end of the elastic member is connected to the clamping member, and the other end of the elastic member is movably connected to the inner wall of the box body. When the handle is in the initial position, the elastic member is in a relaxed state, and at this time, the end of the clamping member away from the transmission member protrudes out of the sliding channel, so that the clamping member is clamped and fixed at the clamping position of the electrical equipment; when the user pulls the handle upward, the transmission member drives the clamping member to slide in the sliding channel, so that the end of the clamping member away from the transmission member no longer protrudes out of the sliding channel, thereby disengaging the clamping position of the box body from the electrical equipment. In this way, through the mutual cooperation of the handle, the transmission member, the clamping member and the elastic member, the quick disassembly and assembly function of the box body is realized, that is, there is no need to use additional auxiliary tools for fixing, which improves the convenience of disassembly and assembly of the battery energy storage box.

[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0035] like Figures 1 to 6 As shown, a battery energy storage box 10 for a battery in one embodiment includes a box body 100, a handle 200 and a snap-on assembly 300, the box body 100 has a receiving cavity 110, the receiving cavity 110 is used to accommodate a battery module, the handle 200 is connected to the box body 100, the box body 100 is provided with a first avoidance hole 120, and the handle 200 is movably arranged in the first avoidance hole 120. The snap-on assembly 300 includes a transmission member 310, a snap-on member 320 and an elastic member 330. The transmission member 310 is connected to the handle 200 and the snap-on member 320, respectively. One end of the elastic member 330 is connected to the snap-on member 320, and the other end of the elastic member 330 is movably connected to the inner wall of the box body 100. Specifically, the other end of the elastic member 330 can abut against the inner wall of the box body 100. The box body 100 is provided with a sliding channel 130. At least a portion of the snap-on member 320 slides through the sliding channel 130. The end of the snap-on member 320 away from the transmission member 310 is used for snapping with the snap-on position of the electrical equipment.

[0036] In this embodiment, there are two snap-in assemblies 300, which are respectively connected to the two sides of the handle 200, so that when the handle 200 moves, the snap-in parts 320 of the snap-in assemblies 300 on both sides move, so that the box 100 is fixed to or detached from the electrical equipment. Specifically, when the handle 200 is in the initial position, that is, when the handle 200 is stationary, the sum of the compression forces of the two elastic members 330 is greater than the total weight of the handle 200, the transmission member 310 and the clamping member 320, that is, the two elastic members 330 are in a relaxed state, so that the two elastic members 330 respectively push one end of the corresponding clamping member 320 out of the sliding channel 130, thereby making the clamping member 320 engage with the clamping position of the electrical equipment; when the user pulls the handle 200 upward, the sum of the travel compression forces of the two elastic members 330 is less than the weight of the battery energy storage box, so that the handle 200 moves upward and drives the clamping member 320 to slide in the sliding channel 130 through the transmission member 310, so that the two elastic members 330 are in a compressed state, thereby making the ends of the two clamping members 320 no longer protrude outside the sliding channel 130, so as to separate the box body 100 from the electrical equipment.

[0037] In the battery energy storage box 10 for the above-mentioned battery, the handle 200 is movably arranged in the first avoidance hole 120, the transmission member 310 is respectively connected to the handle 200 and the clamping member 320, one end of the elastic member 330 is connected to the clamping member 320, and the other end of the elastic member 330 is movably connected to the inner wall of the box body 100. When the handle 200 is located in the initial position, the elastic member 330 is in a relaxed state. At this time, the end of the clamping member 320 away from the transmission member 310 protrudes out of the sliding channel 130, so that the clamping member 320 is clamped and fixed at the clamping position of the electrical equipment; when the user pulls the handle 200 upward, the transmission member 310 drives the clamping member 320 to slide in the sliding channel 130, so that the end of the clamping member 320 away from the transmission member 310 no longer protrudes out of the sliding channel 130, thereby causing the box body 100 to be disengaged from the clamping position of the electrical equipment. In this way, through the cooperation of the handle 200, the transmission member 310, the clamping member 320 and the elastic member 330, the box body 100 can be quickly disassembled and assembled, that is, no additional auxiliary tools are needed for fixing, thereby improving the convenience of disassembly and assembly of the battery energy storage box.

[0038] like Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the transmission member 310 is movably connected to the handle 200 and the clamping member 320 respectively, and the transmission member 310 is used to drive the clamping member 320 away from or close to the clamping position when the handle 200 is pulled up or lowered. In this embodiment, the transmission member 310 is movably connected to the handle 200 and the clamping member 320 respectively, so that when the handle 200 moves in the vertical direction, the clamping member 320 is driven by the transmission member 310 to move in the horizontal direction, thereby achieving the fixing and separation of the box 100 and the electrical equipment.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the transmission member 310 is a first rotating shaft, one end of the first rotating shaft is movably connected to the handle 200, and the other end of the first rotating shaft is movably connected to the clamping member 320, the first rotating shaft is respectively arranged to be inclined relative to the handle 200 and the clamping member 320, the handle 200 and the clamping member 320 intersect in a direction perpendicular to the inner wall of the box body 100, and the center of the first rotating shaft is located on the side of the clamping member 320 away from the first avoidance hole 120. In this embodiment, the transmission member 310 is a first rotating shaft, and the two ends of the first rotating shaft are respectively a first connecting portion and a second connecting portion, the first connecting portion is connected to the handle 200, and the second connecting portion is connected to the clamping member 320, the first rotating shaft is respectively arranged to be inclined with the handle 200 and the clamping member 320, the handle 200 and the clamping member 320 intersect in a direction perpendicular to the inner wall of the box body 100, the center of the first rotating shaft is located on a side of the clamping member 320 away from the first avoiding hole 120, that is, the first rotating shaft is inclined, and the second connecting portion is located above the first connecting portion, when the handle 200 moves upward, the first connecting portion moves upward together, at this time, the first connecting portion forms a horizontal and inward component force on the second connecting portion, that is, the second connecting portion drives the end of the clamping member 320 to move in a direction away from the clamping position of the electrical equipment, so that the elastic member 330 is compressed, and then the clamping member 320 is disengaged from the clamping position of the electrical equipment. Furthermore, when the user releases the handle 200, the handle 200 falls, and the first connection part falls together. At this time, the second connection part no longer has a horizontal inward component force on the clamping member 320, and the elastic member 330 relaxes to make the end of the clamping member 320 protrude outside the sliding channel 130, thereby making the clamping member 320 engage with the clamping position of the electrical device. In this embodiment, the first rotating shaft is movably connected to the clamping member 320 and the handle 200 through a pin and a screw respectively.

[0040] like Figure 4As shown, in one embodiment, the transmission member 310 is a second rotating shaft, one end of the second rotating shaft is movably connected to the handle 200, and the other end of the second rotating shaft is movably connected to the clamping member 320, and the second rotating shaft is located between the handle 200 and the clamping member 320. In this embodiment, one end of the second rotating shaft is movably connected to the handle 200, and the other end of the second rotating shaft is movably connected to the clamping member 320, and the second rotating shaft is located between the handle 200 and the clamping member 320, that is, the clamping member 320, the second rotating shaft and the handle 200 are connected in sequence. When the handle 200 moves upward, the end of the second rotating shaft connected to the handle 200 is pulled and moves upward together, so that the second rotating shaft is tilted. At this time, the end of the second rotating shaft connected to the clamping member 320 generates a horizontal inward component force on the clamping member 320, thereby causing the end of the clamping member 320 to move in a direction away from the clamping position of the electrical equipment, causing the elastic member 330 to be compressed, thereby causing the clamping member 320 to be disengaged from the clamping position of the electrical equipment. Furthermore, when the user releases the handle 200, the handle 200 falls, and the first connection part falls together. At this time, the second connection part no longer has a horizontal inward component force on the clamping member 320, and the elastic member 330 relaxes to make the end of the clamping member 320 protrude outside the sliding channel 130, thereby making the clamping member 320 engage with the clamping position of the electrical device. In this embodiment, the second rotating shaft is movably connected to the clamping member 320 and the handle 200 through a pin and a screw respectively.

[0041] like Figure 5 As shown, in one embodiment, the transmission member 310 is a transmission gear, which is rotatably arranged on the box body 100, the handle 200 is provided with a first transmission tooth, and the handle 200 is meshed and connected with the transmission gear through the first transmission tooth, and the clamping member 320 is provided with a second transmission tooth, and the clamping member 320 is meshed and connected with the transmission gear through the second transmission tooth. In this embodiment, the transmission member 310 is a transmission gear, and the transmission gear is meshed and connected with the handle 200 and the clamping member 320 respectively. When the handle 200 moves in the vertical direction, the handle 200 drives the transmission gear to rotate, and the transmission gear drives the clamping member 320 to move in the horizontal direction, that is, the vertical movement of the handle 200 is converted into the horizontal movement of the clamping member 320 through the transmission gear, thereby realizing the fixing or separation of the box body 100 and the electrical equipment.

[0042] like Figure 3As shown, in one embodiment, the clamping member 320 includes a connecting rod 321 and a clamping block 322, one end of the connecting rod 321 is connected to the transmission member 310, the other end of the connecting rod 321 is connected to the clamping block 322, the clamping block 322 is slidably penetrated in the sliding channel 130, one end of the elastic member 330 is connected to the clamping block 322, and the other end of the elastic member 330 is movably connected to the inner wall of the box body 100. In this embodiment, the connecting rod 321 and the block 322 are an integrally formed structure, the connecting rod 321 is connected to the transmission member 310, and the elastic member 330 is located between the block 322 and the inner wall of the box body 100. When the handle 200 moves upward, the transmission member 310 drives the connecting rod 321 to move inward. At this time, the elastic member 330 is in a compressed state, so that the block 322 no longer protrudes out of the sliding channel 130, thereby causing the box body 100 to be separated from the electrical equipment; when the handle 200 falls, the transmission member 310 no longer generates an inward force on the connecting rod 321. At this time, the elastic member 330 relaxes to push the block 322 out of the sliding channel 130, thereby causing the block 322 to be clamped and fixed to the electrical equipment.

[0043] like Figure 2 and Figure 3 As shown, in one embodiment, the elastic member 330 is sleeved on the connecting rod 321 so that the elastic member 330 is located between the block 322 and the inner wall of the box 100. In this embodiment, the elastic member 330 is a spring, which is sleeved on the connecting rod 321 so that the spring is located between the block 322 and the inner wall of the box 100. When the spring is in a relaxed state, the block 322 is located outside the sliding channel 130 so that the block 322 is engaged with the engaging position of the electrical device. When the spring is in a compressed state, the block 322 retracts into the sliding channel 130 so that the box 100 is separated from the electrical device. Further, in other embodiments, the elastic member 330 can also be other elastic materials such as rubber or silicone.

[0044] like Figure 6 As shown, in one embodiment, the inner wall of the box body 100 is provided with a limit column 140, and the limit column 140 is movably connected with the elastic member 330. In this embodiment, the inner wall of the box body 100 is provided with a limit column 140, and the limit column 140 is provided with a avoidance groove 141, the connecting rod 321 passes through the avoidance groove 141 and is connected with the block 322, and the elastic member 330 is located between the limit column 140 and the block 322, so that the block 322 is close to or away from the clamping position of the electrical equipment.

[0045] like Figure 6As shown, in one embodiment, a clamping column 150 is protruding from the inner wall of the box body 100, and the clamping column 150 is provided with a second avoidance hole 151, and part of the connecting rod 321 is movably inserted into the second avoidance hole 151. It can be understood that part of the structure of the connecting rod 321 is located in the clamping hole of the clamping column 150, so that the clamping column 150 plays a role in limiting and supporting the connecting rod 321.

[0046] like Figure 6 As shown, in one embodiment, a reinforcing rib 160 is convexly provided on the inner side surface of the box body 100, and the reinforcing rib 160 is arranged opposite to the sliding channel 130 so that the reinforcing rib 160 abuts against the block 322. In this embodiment, there are multiple reinforcing ribs 160, and multiple reinforcing ribs 160 are arranged at intervals on the inner side surface of the box body 100 to enhance the structural strength of the box body 100, and the bottom of each reinforcing rib 160 abuts against the block 322 to support the block 322.

[0047] like Figure 1 and Figure 6 As shown, in one embodiment, the box body 100 includes a front shell 100a and a bottom shell 100b, the front shell 100a and the bottom shell 100b are detachably connected, the front shell 100a and the bottom shell 100b together form the accommodating cavity 110, and the first avoidance hole 120 is opened in the front shell 100a. In this embodiment, the front shell 100a and the bottom shell 100b are locked by screws to make the disassembly and assembly of the front shell 100a and the bottom shell 100b more convenient.

[0048] like Figure 1 As shown, in one embodiment, a side of the surface shell 100a away from the bottom shell 100b is provided with a receiving groove 170, the receiving groove 170 is connected to the first avoidance hole 120, and part of the structure of the handle 200 is located in the receiving groove 170. It can be understood that the handle 200 is located in the receiving groove 170, so that the handle 200 is hidden, and the top structure of the battery energy storage box is flatter, thereby making the appearance of the battery energy storage box more beautiful. Furthermore, there is a gap between the handle 200 and the groove wall around the receiving groove 170, so that the human hand can better reach into the receiving groove 170 to grab the handle 200.

[0049] In order to further improve the convenience of battery energy storage box assembly, such as Figure 7As shown, in one embodiment, a guiding slope 322a is provided at one end of the card block adjacent to the card hole, and the guiding slope 322a is used to abut against the groove wall of the card slot of the external electronic device. It can be understood that when the handle is in the initial position, the elastic member is in a relaxed state, so that the card block protrudes out of the card hole. At this time, it is necessary to compress the elastic member by pulling the handle to retract the card block into the card hole, and then release the handle to make the card block snap into the card slot of the external electronic device, thereby completing the fixation of the battery pack. The assembly steps of such a box are still relatively cumbersome. In this embodiment, a guiding slope 322a is provided at one end of the card block adjacent to the card hole, and the guiding slope 322a is used to abut against the groove wall of the card slot of the external electronic device. When the battery pack is assembled, the battery pack is directly placed vertically into the external electronic device. The battery pack is subjected to gravity or pressure applied by the user in the vertical direction, so that when the guiding slope 322a abuts against the groove wall of the card slot, the guiding slope 322a is subjected to a force in the horizontal direction, so that the elastic member is compressed, and then the card block is retracted into the card hole to complete the fixation of the battery pack. That is to say, when the battery pack is assembled, there is no need to pull the handle to operate, and the battery pack assembly can be completed by the gravity of the battery pack or the pressure applied by the user, which further improves the convenience of battery pack assembly.

[0050] It is understandable that when the handle moves to the highest position, the compression of the elastic member reaches the maximum. At this time, the user releases the handle, and the elastic member elastically resets to push the card block out of the card hole. However, due to the excessive elastic force of the elastic member, the card block is quickly pushed out of the card hole, causing the card block to violently collide with the card slot of the external electronic device, especially the end of the card block guide slope 322a collides more violently with the slot wall, which is easy to cause the card block to break after long-term use, thereby reducing the service life of the battery pack. Therefore, in order to reduce the interaction force between the card block and the card slot and increase the service life of the battery pack, as shown in FIG. Figure 7As shown, in one embodiment, the end of the card block adjacent to the card hole is provided with a first arc surface 322b and a second arc surface 322c connected end to end with the guiding inclined surface 322a, and the surface of the first arc surface 322b is provided with an elastic buffer layer (not shown). In this embodiment, the first arc surface 322b is located above the guiding inclined surface 322a, and the second arc surface 322c is located below the guiding inclined surface 322a. When the battery pack is directly placed in the card slot of the electronic device, the second arc surface 322c first abuts against the groove wall of the card slot. Due to the arc setting of the second arc surface 322c, the force when the second arc surface 322c abuts against the groove wall is small, so as to avoid the problem of the card block being damaged due to the large force. Furthermore, if the user pulls the handle to engage the battery pack with the electronic device, since the first curved surface 322b is located above the guiding inclined surface 322a, and the guiding inclined surface 322a is inclined, that is, the first curved surface 322b is located at the outermost side of the card block, when the user releases the handle, the first curved surface 322b first abuts against the groove wall of the card slot, and since the surface of the first curved surface 322b is provided with an elastic buffer layer, when the first curved surface 322b collides with the groove wall, the elastic buffer layer plays a role in reducing the impact force, further avoiding the problem of the card block being damaged due to excessive impact force. Furthermore, the elastic buffer layer can be made of silicone or rubber material and fixed to the surface of the first curved surface 322b by bonding.

[0051] The present application also provides a battery pack, including a battery module and a battery energy storage box 10 for the battery described in any of the above embodiments, wherein the battery module is located in the accommodating cavity 110 and connected to the box body 100 .

[0052] Compared with the prior art, the present invention has at least the following advantages:

[0053] In the battery energy storage box 10 for the above-mentioned battery, the handle 200 is movably arranged in the first avoidance hole 120, the transmission member 310 is respectively connected to the handle 200 and the clamping member 320, one end of the elastic member 330 is connected to the clamping member 320, and the other end of the elastic member 330 is movably connected to the inner wall of the box body 100. When the handle 200 is located in the initial position, the elastic member 330 is in a relaxed state. At this time, the end of the clamping member 320 away from the transmission member 310 protrudes out of the sliding channel 130, so that the clamping member 320 is clamped and fixed at the clamping position of the electrical equipment; when the user pulls the handle 200 upward, the transmission member 310 drives the clamping member 320 to slide in the sliding channel 130, so that the end of the clamping member 320 away from the transmission member 310 no longer protrudes out of the sliding channel 130, thereby causing the box body 100 to be disengaged from the clamping position of the electrical equipment. In this way, through the cooperation of the handle 200, the transmission member 310, the clamping member 320 and the elastic member 330, the box body 100 can be quickly disassembled and assembled, that is, no additional auxiliary tools are needed for fixing, thereby improving the convenience of disassembly and assembly of the battery energy storage box.
