Description

Technical Field

[0001] This utility model belongs to the field of stacking device technology and relates to an energy storage battery stacking device. Background Technology

[0002] An energy storage battery is an integrated unit consisting of a battery energy storage device, a PCS (Power Control System), and a filtering stage. Since an energy storage battery is a single, monolithic structure, laying it flat in the production area would occupy a large space, leading to overcrowding. Therefore, stacking devices are needed to stack and store energy storage batteries.

[0003] A new energy battery stacking rack disclosed in Chinese patent CN221758287U includes a base plate, a load-bearing frame fixedly installed around the perimeter of the base plate, a lower support structure fixedly installed at each of the four corners of the load-bearing frame, an upper support structure movably installed at the upper end of the lower support structure, blocks fixedly installed on the upper surface of the load-bearing frame near the sides and front and rear surfaces, and anti-collision pads fixedly installed on the upper surface of the load-bearing frame near the front and rear surfaces.

[0004] When in use, the support rod is flipped up and pulled upwards, then engaged with the upper end of the concave rod by a triangular limiting block; when not in use, the support rod is rotated to the top of the rubber pads. This results in a fixed distance between the two rubber pads after stacking, which wastes space when placing smaller new energy batteries.

[0005] A battery module stacking rack disclosed in Chinese patent CN221353039U includes multiple support plates. Rectangular sleeves are fixedly installed at the four corners of the top of each support plate. Insert rods are installed inside each rectangular sleeve. Support grooves are provided on the left and right sides of the opening at the top of each rectangular sleeve. Locking blocks that engage with the support grooves are provided on the left and right sides of each insert rod. Grounding feet are fixedly connected to the four corners of the bottom of each support plate.

[0006] When using this stacking rack, rotate and pull down the insert rod to engage the locking block and the support slot, then place the battery on the support plate. However, the distance between the two support plates after stacking is fixed, which wastes space when placing smaller new energy batteries.

[0007] To address the aforementioned problems, this utility model proposes an energy storage battery stacking device. Utility Model Content

[0008] To address the problems existing in the background technology, this utility model proposes an energy storage battery stacking device.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a placement plate, and hollow cylinders are fixedly connected to the four corners of the placement plate. A sliding rod is slidably arranged inside each hollow cylinder. Two sets of snap-fit ​​parts are symmetrically arranged on the outer surface of the sliding rod. Two slots are symmetrically opened on the top surface of the hollow cylinder, and the snap-fit ​​parts are movably arranged in the corresponding slots.

[0010] Each hollow cylinder has a base fixedly connected to its bottom surface, and each slide bar has a stacking cap fixedly connected to its top surface. Each base has a stacking groove on its bottom surface that is compatible with the stacking cap.

[0011] Furthermore, the inner wall of the hollow cylinder is provided with several annular height limiting grooves spaced apart from top to bottom, and two connecting grooves are symmetrically opened on the inner wall of the hollow cylinder. The connecting grooves are arranged vertically and pass through all the height limiting grooves. The connecting grooves and the slots correspond one-to-one.

[0012] Two support blocks are symmetrically fixedly connected to the outer surface of the bottom of the slide bar. The support blocks are slidably set in the corresponding connecting grooves, and a support block can slide in each height limiting groove.

[0013] Furthermore, each set of the snap-fit ​​components includes several snap-fit ​​blocks distributed at intervals from top to bottom, and several sliding grooves are provided on the outer surface of the slide rod. The number of sliding grooves is equal to the number of snap-fit ​​blocks and corresponds one-to-one. The snap-fit ​​blocks are slidably disposed in the corresponding sliding grooves and are movable in the snap-fit ​​slots.

[0014] The width of the card block is greater than the width of the connecting slot, and the height of the card block is greater than the height of the height limiting slot;

[0015] Each block has a first spring fixedly connected to one end, and the other end of the first spring is fixedly connected to the inner wall of the corresponding slide groove.

[0016] Furthermore, a limiting groove is provided on the bottom surface of the middle part of the height limiting groove that is divided into two sections by the connecting groove. The height of the limiting groove is less than the distance between the two height limiting grooves, and each support block can be slidably set in the limiting groove.

[0017] Furthermore, a turntable is coaxially rotatably connected to the bottom surface of the slide rod, and a second spring is fixedly connected to the bottom of the turntable. The bottom end of the second spring is fixedly connected to the inner bottom surface of the hollow cylinder.

[0018] Furthermore, positioning plates are fixedly connected to the four sides of the top surface of the placement plate, and buffer rubber blocks are fixedly connected to one side of each positioning plate near the center of the placement plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This energy storage battery stacking device is equipped with a sliding rod, which is slidably installed inside a hollow cylinder. By sliding the sliding rod up or down, two support blocks slide within corresponding connecting slots. When a support block slides to a suitable height-limiting slot, the sliding rod is rotated horizontally to rotate the support block into the corresponding height-limiting slot. The height-limiting slot prevents the sliding rod from sliding up or down and simultaneously causes a locking block to rotate. When the locking block rotates to the locking slot, the inner wall of the hollow cylinder no longer obstructs the locking block. At this point, a first spring pushes the locking block into the locking slot, preventing the sliding rod from rotating horizontally and positioning the sliding rod inside the hollow cylinder. This allows for adjustment of the height of the sliding rod and the distance between the two placement plates after stacking, making it suitable for stacking energy storage batteries of different sizes and maximizing space utilization.

[0021] 2. The energy storage battery stacking device is equipped with a turntable, which is rotatably connected to the bottom surface of the slide rod. When the slide rod is pulled upward, it will drive the turntable to move together, which will stretch the second spring. When the slide rod moves to a suitable height and the locking block is rotated into the locking groove, the support blocks are respectively located in the corresponding limiting grooves. When the slide rod is released, the second spring will pull the slide rod downward, causing the locking block and support block to move downward, locking the locking block in the bottom end of the locking groove and locking the support block in the limiting groove, thereby fixing the slide rod and increasing its stability.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: an energy storage battery stacking device includes a placement plate 7, with hollow cylinders 1 fixedly connected to each of the four corners of the placement plate 7. The placement plate 7 is located in the middle of the outer surface of the hollow cylinders 1. A sliding rod 2 is slidably arranged inside each hollow cylinder 1.

[0032] The inner wall of the hollow cylinder 1 is provided with several annular height-limiting grooves 103 spaced apart from top to bottom. Two connecting grooves 102 are symmetrically opened on the inner wall of the hollow cylinder 1, and the connecting grooves 102 are arranged vertically. The connecting grooves 102 penetrate all the height-limiting grooves 103, so that the connecting grooves 102 divide the height-limiting grooves 103 into two equal sections.

[0033] Two support blocks 8 are symmetrically fixedly connected to the outer surface of the bottom of the slide bar 2. The support blocks 8 are slidably disposed in the corresponding connecting grooves 102. Each height limiting groove 103 can have a support block 8 sliding in it, allowing the support blocks 8 to slide through the connecting grooves 102 to different height limiting grooves 103.

[0034] Two sets of snap-fit ​​components are symmetrically arranged on the outer surface of the slide rod 2. Two slots 101 are symmetrically opened on the top surface of the hollow cylinder 1, and the snap-fit ​​components are movably disposed in the corresponding slots 101. The connecting groove 102 corresponds vertically to the slots 101.

[0035] Each set of latching components includes several latching blocks 9 spaced apart from top to bottom. Several grooves 201 are formed on the outer surface of the slide rod 2, the number of which is equal to and corresponds one-to-one with the number of latching blocks 9. The latching blocks 9 are slidably disposed within their corresponding grooves 201 and movably disposed within slots 101. The widths of the latching blocks 9 and slots 101 are equal. When a latching block 9 is located within a slot 101, it positions the slide rod 2 on the hollow cylinder 1, preventing the slide rod 2 from rotating.

[0036] The width of the locking block 9 is greater than the width of the connecting groove 102, and the height of the locking block 9 is greater than the height of the height limiting groove 103. When the locking block 9 is located inside the hollow cylinder 1, the inner wall of the hollow cylinder 1 will squeeze the locking block 9, so that the entire locking block 9 is located inside the sliding groove 201.

[0037] Each locking block 9 has a first spring 10 fixedly connected to one end, and the other end of the first spring 10 is fixedly connected to the inner wall of the corresponding slide groove 201. When the first spring 10 is in its natural state, it will push the locking block 9 to the outside of the slide groove 201.

[0038] Each hollow cylinder 1 has a base 4 fixedly connected to its bottom surface. Each slide bar 2 has a stacking cap 3 fixedly connected to its top surface, and each base 4 has a stacking groove on its bottom surface that matches the stacking cap 3. When two placement plates 7 are stacked, the stacking groove allows the base 4 to be secured to the corresponding stacking cap 3, facilitating installation and removal.

[0039] Positioning plates 5 are fixedly connected to the four sides of the top surface of the placement plate 7, and buffer rubber blocks 6 are fixedly connected to one side of each of the four positioning plates 5 near the middle of the placement plate 7.

[0040] Working principle:

[0041] When in use, place the energy storage battery on top of the placement plate 7, between the four positioning plates 5. The buffer rubber block 6 protects the energy storage battery.

[0042] When adjusting the height of the slide bar 2 inside the hollow cylinder 1 according to the size of the energy storage battery, first push the slide bar 2 upward or downward to move the stacking cap 3 upward or downward. This allows the support block 8 to slide inside the connecting groove 102. When the support block 8 is slid to a suitable height limiting groove 103, two of the locking blocks 9 will move to the same horizontal position as the locking groove 101. Rotate the slide bar 2 horizontally to rotate the support block 8 into the height limiting groove 103. At this point, the slide bar 2 can no longer slide up or down, thus limiting the slide bar 2 in the vertical direction.

[0043] The slide bar 2 will drive the locking block 9 to move. When the locking block 9 moves, due to the compression of the inner wall of the hollow cylinder 1, the locking block 9 is always located in the slide groove 201, and the first spring 10 is always in a compressed state.

[0044] When the locking block 9 is rotated to the corresponding slot 101, the first spring 10 pushes the locking block 9 into the slot 101. At this time, the slide rod 2 can no longer rotate, thus limiting the slide rod 2 in the horizontal direction. This fixes the slide rod 2 onto the hollow cylinder 1.

[0045] After adjustment, when stacking the two placement plates 7, ensure that the two placement plates 7 are aligned vertically, so that the base 4 on the upper placement plate 7 is engaged with the stacking cap 3 on the lower placement plate 7.

[0046] Example 2: As Figures 6-7 As shown, the difference between this embodiment and Embodiment 1 is that: Limiting grooves 104 are provided on the bottom surface of the middle part of the height-limiting groove 103, which is divided into two sections by the connecting groove 102. The height of the limiting groove 104 is less than the distance between the two height-limiting grooves 103. The limiting groove 104 does not connect adjacent height-limiting grooves 103. Each support block 8 can be slidably disposed within the limiting groove 104. The width of the limiting groove 104 is less than the width of the locking block 9. When the locking block 9 moves to the limiting groove 104, it will still be pressed into the sliding groove 201.

[0047] The bottom surface of the slide rod 2 is coaxially rotatably connected to the turntable 11, allowing the slide rod 2 to rotate on the top of the turntable 11. A second spring 12 is fixedly connected to the bottom of the turntable 11, and the bottom end of the second spring 12 is fixedly connected to the inner bottom surface of the hollow cylinder 1. When the support block 8 is located at the bottommost end of the connecting groove 102, the second spring 12 is in a stretched state, causing the second spring 12 to exert a downward force on the turntable 11.

[0048] Working principle:

[0049] In use, when adjusting the height of the slide rod 2 inside the hollow cylinder 1, first slide the slide rod 2 upwards, causing the support block 8 to slide upwards inside the connecting groove 102. This drives the turntable 11 to move upwards, further stretching the second spring 12.

[0050] When the support block 8 is slid into a suitable height-limiting groove 103, two of the locking blocks 9 will move to the same horizontal position as the groove 101. The slide rod 2 is then rotated horizontally to move the support block 8 into the height-limiting groove 103. At this point, the slide rod 2 can no longer slide up or down, thus limiting its vertical movement. The slide rod 2 will then rotate at the top of the turntable 11.

[0051] The slide bar 2 will drive the locking block 9 to move. When the locking block 9 is rotated to the corresponding slot 101, the first spring 10 will push the locking block 9 into the slot 101, and at the same time the support block 8 will move to the limiting slot 104.

[0052] When the slide rod 2 is released, the second spring 12 pulls the slide rod 2 downwards, causing the support block 8 to slide downwards into the corresponding limiting groove 104. This continues until the locking block 9 is at the bottom of the locking groove 101, at which point the slide rod 2 can no longer rotate. This horizontally limits the slide rod 2, thus fixing it to the hollow cylinder 1.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
