Description

Technical Field

[0001] This utility model relates to the field of battery pack hoisting technology, and in particular to a stable structure for a telescopic mechanism. Background Technology

[0002] In the production and maintenance of new energy vehicles, the battery pack hoisting process plays a crucial role, and its importance cannot be overstated. As the core energy storage unit of a vehicle, the internal structure of the battery pack is incredibly sophisticated. It contains numerous high-energy-density battery modules, which are key components for energy storage and release. These modules are manufactured with meticulous processes and are extremely sensitive to environmental and external impacts. Simultaneously, it is equipped with complex electrical components responsible for precisely controlling the battery's charging and discharging process, monitoring battery status, and other vital functions.

[0003] However, during hoisting, even the slightest instability can lead to serious consequences. Even a slight sway could cause the battery pack to rub against surrounding equipment or the hoisting device. If the battery pack casing is damaged by friction, the sealing of the internal battery modules will be compromised, potentially causing bulging. This not only poses a serious threat to the safety of nearby operators but also damages expensive equipment. This patent provides a stabilizing structure for a telescopic mechanism to alleviate the aforementioned technical problems in the prior art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. During hoisting, even the slightest instability can lead to serious consequences. Even minor shaking can cause the battery pack to collide with surrounding equipment or the hoisting device. If the battery pack casing is damaged by collision, the sealing of the internal battery modules will be compromised, potentially causing bulging. This poses a serious threat to the safety of nearby operators and can also damage expensive equipment. Therefore, this invention proposes a stabilizing structure for the telescopic mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stabilizing structure for a telescopic mechanism includes a protective box and a lifting block. A fixed tube is fixedly connected to the bottom of the lifting block. An internal rack is provided inside the fixed tube. The internal rack is meshed with a column-side gear. The column-side gear is driven by a connecting rod. The end of the connecting rod away from the supporting column is driven by a box-side gear. The box-side gear is meshed with a narrow rack. A sliding plate is provided at the bottom of the narrow rack. A stabilizing mechanism for preventing battery impact is provided inside the protective box. The stabilizing mechanism includes an internal rack in the plate at the bottom of the protective box. The internal rack is meshed with an internal gear in the slot. The internal gear in the slot is driven by a rotating bar. A first bending bar is meshed with one side of the rotating bar. The first bending bar is rotatably connected to a first sliding block. A semicircular plate is slidably connected to the first sliding block. A second sliding block is slidably connected to the side of the semicircular plate away from the first sliding block. The second sliding block is rotatably connected to a second bending bar. The side of the second bending bar away from the second sliding block is rotatably connected to the rotating bar.

[0007] The above technical solution further includes:

[0008] The column-side gear is driven by a column-side belt. The end of the column-side belt away from the column-side gear passes through the support column and is driven by a connecting rod. The end of the connecting rod away from the support column is driven by a box-side belt. The end of the box-side belt away from the connecting rod is driven by a box-side gear. The box-side gear is rotatably connected to the protective box. The sliding plate is slidably connected to the protective box. The gear in the groove is rotatably connected to a short plate. The short plate is fixed to one side of the lowering U-shaped plate. The gear in the groove is driven by a connecting belt. The end of the connecting belt away from the gear in the groove is driven by a rotating bar. The side of the semi-circular plate is fixedly connected to an installation block. The installation block is fixed to the bottom of the lowering U-shaped plate.

[0009] The side of the downward-moving U-shaped plate has a square groove for placing the gear inside the slot.

[0010] The first sliding block has memory foam on its side for restoring elasticity, and the second sliding block also has memory foam on its side near the first sliding block for restoring elasticity.

[0011] The protective box is equipped with a block on top for rotating with the connecting rod.

[0012] The bottom of the semicircular plate is provided with a protrusion for the first sliding block and the second sliding block to slide.

[0013] The surface of the sliding plate is provided with soft padding to prevent the battery pack from falling and getting bumped.

[0014] A support column is fixedly connected to the top of the protective box, and the side of the support column is provided with a groove for the transmission of the column-side belt. This ensures the structural stability of the protective box during movement, battery pack grabbing, and hoisting, prevents the protective box from detaching from the hoisting mechanism, effectively avoids the risk of the battery pack falling due to unstable connection of the protective box, and greatly improves the safety of the entire hoisting operation.

[0015] The support column is rotatably connected to a connecting rod. When it is necessary to adjust the angle or position of the protective box during hoisting, the slotted joint with the transmission of the belt on the column side ensures the accuracy and continuity of the operation, avoids operational errors caused by belt slippage or misalignment, and enhances the control precision and reliability of the hoisting system.

[0016] The fixed tube is slidably connected to a support column. When it is necessary to adjust the vertical distance between the protective box and the battery pack, the support column can smoothly slide up and down within the fixed tube through the meshing of the gear on the column side and the rack inside the fixed tube, moving the protective box closer to or away from the battery pack. This sliding connection method ensures the stability and accuracy of the protective box's vertical movement, preventing the protective box from swaying or shifting during lifting, thereby ensuring accurate positioning when grabbing the battery pack and improving the precision and safety of the hoisting operation.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the lifting blocks move precisely along the track, which, in conjunction with the support columns, drives the protective box to rise and fall smoothly. A precision transmission system composed of gears, belts, and other components ensures that the protective box is accurately positioned above the battery pack before hoisting and firmly holds the battery pack during transport, greatly reducing battery pack swaying. This prevents collisions with surrounding equipment or hoisting devices caused by swaying, effectively protecting the battery pack casing.

[0019] 2. In this invention, during hoisting, the coordinated action of opening and closing the bottom holes of the protective box, the downward movement of the U-shaped plate, and the sliding block can firmly secure the battery pack. Even in complex production environments, it can resist external interference and prevent the battery pack from shaking or falling. This not only eliminates the serious threat to the lives of surrounding operators but also avoids casualties caused by battery pack accidents. Attached Figure Description

[0028] Please see Figures 1-6 As shown, this utility model is a stabilizing structure for a telescopic mechanism, including a protective box 1 and a lifting block 2. A fixed tube 3 is fixedly connected to the bottom of the lifting block 2. An internal rack 24 is provided inside the fixed tube 3. The internal rack 24 is meshed with a column-side gear 4.

A stabilizing mechanism for preventing battery impact is provided inside the protective box 1. The stabilizing mechanism includes components installed in the protective box. 1. A rack 13 is located at the bottom of the plate. The rack 13 is meshed with a gear 14 in the slot. The gear 14 in the slot is connected to a rotating bar 20. One side of the rotating bar 20 is meshed with a first bent bar 21. The first bent bar 21 is rotatably connected to a first sliding block 18. The first sliding block 18 is slidably connected to a semicircular plate 16. The side of the semicircular plate 16 away from the first sliding block 18 is slidably connected to a second sliding block 19. The second sliding block 19 is rotatably connected to a second bent bar 22. The side of the second bent bar 22 away from the second sliding block 19 is rotatably connected to the rotating bar 20.

[0029] In one embodiment, for the aforementioned column-side gear 4, the column-side gear 4 is driven by a column-side belt 5. The end of the column-side belt 5 away from the column-side gear 4 passes through the support column 10 and is driven by a connecting rod 6. The end of the connecting rod 6 away from the support column 10 is driven by a box-side belt 7. The end of the box-side belt 7 away from the connecting rod 6 is driven by a box-side gear 8. The box-side gear 8 is rotatably connected to the protective box 1. The sliding plate 11 is slidably connected to the protective box 1. The slot gear 14 is rotatably connected to a short plate 23. The short plate 23 is fixed to one side of the downward U-shaped plate 12. The slot gear 14 is driven by a connecting belt 15. The end of the connecting belt 15 away from the slot gear 14 is driven by a rotating bar 20. The side of the semi-circular plate 16 is fixedly connected to an mounting block 17. The mounting block 17 is fixed to the bottom of the downward U-shaped plate 12.

[0030] In one embodiment, the lowering U-shaped plate 12 has a square groove on its side for placing the gear 14 inside the slot.

[0031] In one embodiment, the first sliding block 18 is provided with memory foam for restoring elasticity on its side, and the second sliding block 19 is also provided with memory foam for restoring elasticity on the side close to the first sliding block 18.

[0032] In one embodiment, for the aforementioned protective box 1, a block is provided on top of the protective box 1 for rotatably connecting with the connecting rod 6.

[0033] In one embodiment, the bottom of the semicircular plate 16 is provided with a protrusion for sliding between the first sliding block 18 and the second sliding block 19.

[0034] In one embodiment, the surface of the sliding plate 11 is provided with soft cotton to prevent the battery pack from falling and getting bumped.

[0035] In one embodiment, the support column 10 is fixedly connected above the protective box 1, and the side of the support column 10 is provided with a groove for the column-side belt 5 to drive the transmission.

[0036] In this embodiment, the structural stability of the protective box 1 is ensured during the movement, grabbing of the battery pack and hoisting process, preventing the protective box 1 from detaching from the hoisting mechanism, effectively avoiding the risk of the battery pack falling due to the unstable connection of the protective box 1, and greatly improving the safety of the entire hoisting operation.

[0037] In one embodiment, the support column 10 is rotatably connected to the connecting rod 6.

[0038] In this embodiment, when the angle or position of the protective box 1 needs to be adjusted during the hoisting process, the transmission of the slotted belt 5 on the column side can ensure the accuracy and continuity of the action, avoid operational errors caused by belt slippage or misalignment, and enhance the control precision and reliability of the hoisting system.

[0039] In one embodiment, the fixed tube 3 is slidably connected to a support column 10.

[0040] In this embodiment, when it is necessary to adjust the vertical distance between the protective box 1 and the battery pack, the support column 10 can smoothly slide up and down within the fixed tube 3 through the meshing of the column-side gear 4 and the rack 24 inside the fixed tube 3, thereby moving the protective box 1 closer to or away from the battery pack. This sliding connection method ensures the stability and accuracy of the protective box 1's vertical movement, preventing the protective box 1 from shaking or shifting during lifting, thus ensuring accurate positioning when grabbing the battery pack and improving the precision and safety of the hoisting operation.

[0041] The working principle of the stabilizing structure for the telescopic mechanism in this utility model is as follows: First, the lifting block 2 moves along the track for transporting the battery pack. Then, when it reaches a position where it can grab the battery pack, the column-side gear 4 is rotated. The rotation of the column-side gear 4 engages with the rack 24 inside the fixed tube 3, thereby causing the support column 10 to move the protective box 1 downward. When it moves to a relatively close distance above the battery pack, the rotation of the column-side gear 4 simultaneously drives the connecting rod 6 to rotate via the column-side belt 5. The rotation of the connecting rod 6 then drives the box-side gear 8 to rotate via the box-side belt 7. At this moment, when the protective box 1 is close to the battery pack, the side gear 8 engages with the narrow rack 9, exposing the hole at the bottom of the protective box 1. Then, the gear 14 inside the slot rotates, engaging with the rack 13 inside the plate of the protective box 1, causing the lower U-shaped plate 12 to move downwards. Simultaneously, the rotation of the gear 14 inside the slot drives the rotating bar 20 to rotate via the connecting belt 15. The rotation of the rotating bar 20 twists one side of the first bent bar 21 and the second bent bar 22, respectively. Figure 5 For example, when the end of the first bent strip 21 closest to the rotating strip 20 is twisted, the end of the first bent strip 21 away from the rotating strip 20 will cause the first sliding block 18 to move away from the side of the second sliding block 19. At the same time, while the rotating strip 20 twists the first bent strip 21, it will also twist one side of the second bent strip 22, so that the second bent strip 22 will cause the second sliding block 19 to move away from the side of the first sliding block 18 during the rotation process.

[0042] When the downward-moving U-shaped plate 12 moves down to both sides of the bottom of the battery pack, the gear 14 in the reverse control slot rotates. The rotation of the gear 14 in the slot drives the connecting belt 15 in the reverse direction. The connecting belt 15 then drives the rotating bar 20 to twist in the reverse direction, causing the first sliding block 18 and the second sliding block 19 to move closer to each other under the twisting of the first bending bar 21 and the second bending bar 22. Memory foam is placed on the sides of both the first sliding block 18 and the second sliding block 19, which gradually tightens during the clamping of the battery pack. When the gear 14 in the slot meshes with the rack 13 in the plate, it drives the downward-moving U-shaped plate 12 to move upward, thus holding the battery pack and entering the interior of the lifting block 2. At this time, the column-side gear 4 continues to rotate. The rotation of the column-side gear 4 then drives the connecting rod 6 to rotate in the reverse direction using the column-side belt 5. The connecting rod 6 then drives the box-side gear 8 to rotate in the reverse direction using the box-side belt 7, thus meshing with the narrow rack 9 and causing the sliding plate 11 to block the bottom of the protective box 1, thereby preventing the battery pack from falling.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
