[0030] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] See Figure 1 , for the sake of clarity, Figure 1 The X direction represents the length direction of the carrier 3 .

[0032] An embodiment of the present application provides a tool cart, which can be mainly used for installing and removing battery packs 10. The tool cart includes a lifting mechanism 2 and a carrier 3. The carrier 3 and the lifting mechanism 2 are slidably connected. The carrier 3 can be selectively extended or retracted to the lifting mechanism 2. The lifting mechanism 2 is used to adjust the height of the carrier 3. The carrier 3 is formed with a first opening 31, which is used for allowing materials to enter and leave the carrier 3.

[0033] In actual application, the carrier 3 can adopt a rectangular frame structure, and the carrier 3 and the lifting mechanism 2 are slidably connected to facilitate adjustment of the horizontal distance of the carrier 3 relative to the battery pack 10 (battery cabinet). Specifically, taking the placement of the battery pack 10 on a tool cart as an example, the operator moves the tool cart to the position where the battery pack 10 needs to be removed; then, the height of the carrier 3 is adjusted by the lifting mechanism 2 so that the height of the carrier 3 matches the height of the battery pack 10 that needs to be taken out and transported; then, the operator controls the carrier 3 to slide on the lifting mechanism 2, so that the carrier 3 moves horizontally on the lifting mechanism 2, and the carrier 3 extends from the lifting mechanism 2 and approaches the battery pack 10 until the first port 31 of the carrier 3 is aligned with the battery pack 10. The battery pack 10 is seamlessly docked (or nearly seamlessly docked), so the operator can directly move the battery pack 10 to the carrier 3 through the first port 31, and then retract the carrier 3 to the lifting mechanism 2, and the loading of the battery pack 10 is completed; then, the tool cart is moved to the predetermined installation position of the battery pack 10 (such as a battery cabinet), and the lifting mechanism 2 is used again to adjust the height of the carrier 3 so that it is consistent with the height of the predetermined installation position on the battery cabinet, and the carrier 3 is moved again so that it extends from the lifting mechanism 2, and the first port 31 is seamlessly docked (or nearly seamlessly docked) with the predetermined installation position of the battery cabinet. In this way, the operator can directly push the battery pack 10 in the carrier 3 out and push it into the battery cabinet to complete the entire installation process.

[0034] Compared with the prior art, the carrier 3 and the lifting mechanism 2 of the present application are slidably connected, and the lifting mechanism 2 can realize position adjustment of the carrier 3 and the battery pack 10 in the vertical direction, so that the carrier 3 and the battery pack 10 are aligned in the height direction to meet the height requirements of different battery packs 10; in addition, the carrier 3 can slide relative to the lifting mechanism 2, and the lateral sliding of the carrier 3 can realize seamless docking of the carrier 3 with the battery pack 10 or the battery cabinet, thereby improving the accuracy of docking and effectively avoiding the occurrence of gaps between the carrier 3 and the cabinet. The operator does not need to repeatedly adjust the overall position of the tool cart, but only needs to slide the carrier 3 after the lifting mechanism 2 has adjusted the height to realize precise docking of the carrier 3 and the battery pack 10, thereby greatly improving work efficiency, reducing labor intensity, and reducing bumps and damage to the battery pack 10 during loading and unloading.

[0035] See again Figure 1 The tool cart includes a moving seat 1, and a lifting mechanism 2 is connected to the moving seat 1.

[0036] In practical applications, the mobile base 1 serves as the bottom support structure of the entire tool cart and has sufficient stability to bear the weight of the battery pack 10. A plurality of universal wheels are provided at the bottom of the mobile base 1, so that the tool cart can be flexibly moved to a desired position.

[0037] See Figure 2The lifting mechanism 2 includes a support plate 21 and a sliding portion 24. The support plate 21 is formed with a U-shaped groove 211. The support plate 21 is connected to the sliding portions 24 on opposite sides of the U-shaped groove 211. The sliding portions 24 at least partially extend out of the U-shaped groove 211. The supporting member 3 is slidably connected to the sliding portion 24. The supporting member 3 can be selectively extended or retracted into the U-shaped groove 211.

[0038] In actual applications, the width of the U-shaped groove 211 can be slightly larger than the width of the carrier 3. The function of the U-shaped groove 211 is to provide installation space for the carrier 3, and the U-shaped groove 211 is formed with an opening, which facilitates the carrier 3 to slide out of the support plate 21, so that the carrier 3 can be precisely aligned with the battery pack 10.

[0039] The sliding portion 24 can be a rectangular strip, extending beyond the support plate 21 to allow the carrier 3 to slide a greater distance. The sliding portion 24 is provided with a slide groove 241. A slider is provided on the side of the carrier 3 to engage with the slide groove 241. The slider slides within the slide groove 241 to extend and retract the carrier 3 from the support plate 21. The closed ends of the slide groove 241 limit the maximum extension and retraction distances of the carrier 3, preventing it from falling off the support plate 21.

[0040] See again Figure 2 The lifting mechanism 2 includes a support frame 22, and multiple support plates 21 are arranged in sequence along the height direction of the lifting mechanism 2. A support frame 22 is connected between any two adjacent support plates 21, and the support frame 22 is used to adjust the height between the two adjacent support plates 21; the bearing member 3 is located in the U-shaped groove 211 of one or more support plates 21.

[0041] In actual application, the lifting mechanism 2 includes three support plates 21 as an example. The lifting mechanism 2 includes three support plates 21: a first support plate 21, a second support plate 21, and a third support plate 21. The first support plate 21 is located at the bottom and is connected to the movable base 1. The third support plate 21 is located at the top and is used to support the load-bearing member 3 and is slidably connected to the load-bearing member 3. The second support plate 21 is located between the first and third support plates 21. A support frame 22 is connected between the first and second support plates 21, and a support frame 22 is connected between the second and third support plates 21.

[0042] Taking the height adjustment between the first support plate 21 and the second support plate 21 as an example, the lifting mechanism 2 further includes a power member 23. The support frame 22 may include a first rod 221 and a second rod 222. The first rod 221 and the second rod 222 are connected to each other in a cross shape. The first end of the first rod 221 is rotatably connected to the first support plate 21, and the second end of the first rod 221 is slidably connected to the second support plate 21. The first end of the second rod 222 is slidably connected to the first support plate 21, and the second end of the second rod 222 is rotatably connected to the second support plate 21. The driving end of the power member 23 is connected to the first rod 221 or the second rod 222. The power member 23 drives the movement of the first rod 221 or the second rod 222 to slide the first rod 221 and the second rod 222, thereby adjusting the height of the second support plate 21. The power member 23 may be a linear actuator.

[0043] It should be noted that the support frame 22 may also directly adopt a telescopic structure, and the height of the support plate 21 can be adjusted by the telescopic movement of the support frame 22 itself.

[0044] Each support plate 21 is provided with a U-shaped groove 211. The U-shaped groove 211 provides space for the carrier 3 during the raising and lowering of the support plate 21, thereby preventing interference between the carrier 3 and the support plate 21. When the support frame 22 adjusts the height between two adjacent support plates 21, the carrier 3 can be positioned within the U-shaped groove 211 of one or more support plates 21, enabling barrier-free raising and lowering of the carrier 3.

[0045] See again Figure 2 The carrying member 3 includes a fixed frame 33, a chassis 34 and a telescopic member 35. The fixed frame 33, the telescopic member 35 and the chassis 34 enclose a first opening 31. The fixed frame 33 is slidably connected to the lifting mechanism 2. The fixed frame 33 is connected to the telescopic member 35. The driving end of the telescopic member 35 is connected to the chassis 34. The telescopic member 35 is used to adjust the height between the fixed frame 33 and the chassis 34. The chassis 34 is used to carry materials.

[0046] In actual application, the fixing frame 33 and the support plate 21 are slidably connected, and a connecting seat can be provided on each of the four corners of the fixing frame 33 for connecting the telescopic member 35. The telescopic member 35 can be an electric hydraulic cylinder, which is respectively installed on the four connecting seats of the fixing frame 33. The cylinder body of the telescopic member 35 is connected to the fixing frame 33, and the piston rod is connected to the chassis 34. The telescopic member 35 can achieve precise height adjustment of the chassis 34 relative to the fixing frame 33. First, the height of the bearing member 3 is roughly adjusted by the lifting mechanism 2, and then the height of the chassis 34 is roughly adjusted so that the position of the chassis 34 is roughly aligned with the position of the battery pack 10; then the height of the chassis 34 is finely adjusted by the telescopic member 35 so that the height of the chassis 34 is accurately matched with the height of the installation or removal position of the battery pack 10, which facilitates the installation and removal of the battery pack 10.

[0047] See again Figure 2 The carrier 3 includes a plurality of rollers 38, which are rotatably connected to the chassis 34 in sequence, and are used to carry materials.

[0048] In practical applications, the roller 38 can be cylindrical in shape, with a length equal to or approximately equal to the width of the chassis 34. A bearing can be provided at each end of the roller 38, mounted on the side of the chassis 34, allowing the roller 38 to rotate freely on the chassis 34. Multiple rollers 38 are evenly distributed on the chassis 34 to evenly bear the weight of the battery pack 10. The surface of the roller 38 is smooth and has a low coefficient of friction, making it easy for the battery pack 10 to slide on it. The direction of rotation of the roller 38 is consistent with the direction of movement of the battery pack 10, reducing the friction when the battery pack 10 moves, allowing the battery pack 10 to more easily enter or exit the carrier 3.

[0049] See again Figure 2 The carrier 3 is formed with a first opening 31 and a second opening 32 which are oppositely arranged along its length direction. The first opening 31 and the second opening 32 are both used for allowing materials to enter and leave the carrier 3.

[0050] In actual applications, the space for transporting the battery pack 10 is usually relatively small, and the tool cart often has difficulty in turning. In order to solve this problem, the carrier 3 of the present application forms a first port 31 and a second port 32 that are relatively set. The first port 31 and the second port 32 can both be used for the battery pack 10 to enter and exit. In other words, the battery pack 10 can enter and exit both opposite sides of the tool cart. Therefore, when installing and removing the battery pack 10 at different positions, the tool cart does not need to turn, and only needs to move in a straight line in a small space to complete the transfer, which significantly improves the convenience and safety of operation, is suitable for a variety of complex scenarios, and optimizes the transportation process of the battery pack 10.

[0051] See Figure 3 The tool cart includes a first driving member 4 and a first traction member (not shown in the figure). The first driving member 4 is connected to the lifting mechanism 2. The driving end of the first driving member 4 is connected to the first traction member. The first traction member is used to pull the material into the carrier 3 from the first port 31 and pull out the carrier 3 from the second port 32.

[0052] In actual use, the first driving member 4 can be installed at one end of the support plate 21 near the second opening 32. When the battery pack 10 needs to be transported to the carrier 3, the first traction member is wound out from the driving end of the first driving member 4, extends to the first opening 31, and then passes through the first opening 31 and connects to the battery pack 10. When the first driving member 4 is activated, the first traction member winds up, pulling the battery pack 10 from the first opening 31 into the carrier 3. When the battery pack 10 needs to be removed from the carrier 3, the first driving member 4 continues to be activated, and the first traction member continues to wind up, pulling the battery pack 10 toward the second opening 32 until the battery pack 10 is completely separated from the carrier 3 and removed from the second opening 32. This design does not require the tool cart to be turned around; the tool cart only needs to adjust its height and translation position to achieve the transportation of the battery pack 10.

[0053] The first driving member 4 may be a winch or other structure, and the first traction member may be a traction rope. It should be noted that the height at which the first driving member 4 is installed should be lower than the height of the chassis 34 .

[0054] See again Figure 3 The tool cart includes a second driving member 5 and a second traction member (not shown in the figure). The second driving member 5 is connected to the carrier 3 and is located at the opposite ends of the carrier 3 with the first driving member 4. The driving end of the second driving member 5 is connected to the second traction member. The second traction member is used to pull the material into the carrier 3 from the second port 32 and pull the carrier 3 out from the first port 31.

[0055] In actual application, the second driving member 5 can be installed at one end of the carrier 3 close to the first port 31, and the second traction member is wound around the second driving member 5, extended to the second port 32, passed through the second port 32 and connected to the battery pack 10. When the second driving member 5 is started, the second traction member is wound to pull the battery pack 10 into the carrier 3 from the second port 32; when the battery pack 10 needs to be pulled out of the carrier 3, the second driving member 5 is continued to be started, and the second traction member continues to wind to pull the battery pack 10 toward the first port 31 until the battery pack 10 is completely detached from the carrier 3 and moved out from the first port 31.

[0056] The second driving member 5 can be a winch or other structure, and the second traction member can be a traction rope. It should be noted that the installation height of the second driving member 5 should be lower than the height of the chassis 34.

[0057] By cooperating with the first drive member 4 and the second drive member 5, the tool cart can achieve bidirectional movement of the battery pack 10 within the carrier 3, increasing the flexibility and applicability of the tool cart. The two drives can be controlled independently or work in conjunction to meet different operational requirements.

[0058] See again Figure 3The tool cart includes a baffle 6, and the carrier 3 is provided with a plurality of fixing holes 36 along its length direction. The baffle 6 is inserted into some of the fixing holes 36, and the baffle 6 is used to limit the movement of materials along the length direction of the carrier 3.

[0059] In practical applications, the baffle 6 can be a rectangular plate with a width approximately equal to that of the carrier 3. The baffle 6 is provided with multiple locating pins at its bottom. The diameter of the locating pins matches the diameter of the fixing holes 36 on the carrier 3. The locating pins are inserted into the fixing holes 36 to secure the baffle 6 to the carrier 3. The carrier 3 has multiple fixing holes 36 uniformly defined along its length. The baffle 6 can be inserted into any of the fixing holes 36. The position of the baffle 6 can be adjusted according to the length of the battery pack 10 to restrict the movement of the battery pack 10 along the length of the carrier 3.

[0060] See again Figure 3 The tool cart includes a limiting member 8, and the carrier 3 is provided with a plurality of insertion holes 37 along its circumference. The limiting member 8 is inserted into the insertion holes 37, and the limiting member 8 is used to limit the material.

[0061] In practical applications, the stopper 8 can be cylindrical, with a diameter slightly smaller than the insertion hole 37. Once inserted into the insertion hole 37, the stopper 8 prevents lateral movement of the battery pack 10. The insertion holes 37 are evenly distributed around the carrier 3. The stopper 8 can be flexibly adjusted according to the width of the battery pack 10, limiting its position and movement along the width of the carrier 3. The combination of the baffle 6 and the stopper 8 effectively secures the battery pack 10 on the carrier 3, preventing displacement during movement and improving the safety and reliability of the tool cart.

[0062] See Figure 4 The tool cart includes a support plate 9, which is slidably arranged with the support plate 9 and the support member 3 along the length direction of the support member 3; the support plate 9 extends toward the support member 3, and along the length direction of the support member 3, the projection area of ​​the support plate 9 at least partially covers the first opening 31 and / or the second opening 32.

[0063] In actual applications, since the first traction member or the second traction member can only exert a pulling force on the battery pack 10, when the battery pack 10 needs to be placed in the carrier 3, the first traction member or the second traction member can pull the battery pack 10 completely into the carrier 3, but when the battery pack 10 needs to be pushed out of the carrier 3, the distance that the first traction member or the second traction member can pull the battery pack 10 is limited, and the battery pack 10 cannot be completely pulled out of the carrier 3. Only most of the battery pack 10 can be pulled out of the carrier 3, and the remaining part needs to be completely pulled out manually or mechanically.

[0064] Based on this, the present application provides a push plate 9, and the supporting member 3 and the push plate 9 are slidingly arranged to achieve the movement of the push plate 9 relative to the supporting member 3. When the battery pack 10 needs to be pushed out from the first port 31 or the second port 32, the push plate 9 is pushed to move relative to the supporting member 3. At this time, the push plate 9 pushes the battery pack 10 to move until the battery pack 10 is pushed out from the first port 31 or the second port 32. The sliding design of the push plate 9 ensures the smoothness and accuracy of the push of the battery pack 10, further improving the operational convenience and work efficiency of the tool vehicle. The projected area of ​​the push plate 9 at least partially covers the first port 31 and / or the second port 32, ensuring that the push plate 9 can contact the battery pack 10, thereby pushing the battery pack 10 to move.

[0065] It should be noted that the sliding setting of the support plate 9 and the supporting member 3 can adopt a sliding connection between the support plate 9 and the supporting member 3, or a fixed connection between the support plate 9 and the support plate 21, both of which can achieve relative sliding of the support plate 9 and the supporting member 3.

[0066] See Figure 5 The tool cart includes a third driving member 7, which is connected to the support plate 21. The driving end of the third driving member 7 is connected to the carrier 3, and the third driving member 7 is used to drive the carrier 3 to extend or retract to the support plate 21.

[0067] In practice, the third drive element 7 can be an electro-hydraulic cylinder mounted at one end of the support plate 21. The cylinder body of the electro-hydraulic cylinder is fixedly connected to the support plate 21, and the piston rod is connected to the carrier 3. This third drive element 7 allows the operator to easily control the extension and retraction of the carrier 3, eliminating the need for manual pushing and pulling of the carrier 3. This reduces operator workload and improves work efficiency. Furthermore, the precise control capabilities of the electro-hydraulic cylinder ensure smoother and more accurate extension and retraction of the carrier 3, enhancing the tool cart's operational performance and safety.

[0068] See again Figure 5 The carrier 3 includes an abutting boss 341 . The carrier 3 is provided with an abutting boss 341 on one side of the first opening 31 and / or the second opening 32 . The abutting boss 341 extends in a direction away from the carrier 3 and beyond the carrier 3 .

[0069] In actual application, the abutment boss 341 is connected to the chassis 34, and the abutment boss 341 extends in the direction away from the carrier 3. The abutment boss 341 protrudes from the carrier 3. The abutment boss 341 should usually be close to the height of the chassis 34 and should not be lower than the chassis 34. The main function of the abutment boss 341 is to push the battery pack 10 to the predetermined position and provide a transition platform for the battery pack 10 to facilitate the battery pack 10 to enter or leave the carrier 3 more stably.

[0070] When the battery pack 10 needs to be transported to the carrier 3, the abutment boss 341 is aligned with the height of the battery pack 10 through dual adjustment of the lifting mechanism 2 and the telescopic member 35, and then the carrier 3 is driven to slide by the third driving member 7, and the horizontal distance between the abutment boss 341 and the battery pack 10 is adjusted, and then the battery pack 10 is pulled into the carrier 3 by the first traction member or the second traction member. The abutment boss 341 provides a transition contact surface, and the battery pack 10 is first pulled onto the abutment boss 341, and the battery pack 10 can smoothly enter the carrier 3 through the abutment boss 341.

[0071] When the battery pack 10 needs to be pushed out of the carrier 3 and into the battery rack, the position of the carrier 3 is adjusted so that the abutment boss 341 and the battery rack are aligned in height and in contact with each other. The first traction member (or second traction member or abutment plate 9) is used to pull (push) the battery pack 10 from the carrier 3 to the abutment boss 341. The abutment boss 341 provides a transitional contact surface, allowing the battery pack 10 to accurately and smoothly enter the battery rack through the abutment boss 341. Since the first traction member or the second traction member cannot completely push the battery pack 10 into the battery rack, only a large part of the battery pack 10 enters the battery rack. At this time, the abutment boss 341 can be moved to push the battery pack 10 into the battery rack.

[0072] Specifically, after the battery pack 10 partially enters the battery rack, it is primarily supported by the battery rack. Therefore, the carrier 3 can be moved to disengage it from the battery pack 10. The height of the carrier 3 is then adjusted so that the abutment boss 341 can abut against the battery pack 10. The third drive member 7 then drives the carrier 3 toward the battery pack 10, causing the abutment boss 341 to abut against the battery pack 10, thereby completely pushing the battery pack 10 into the battery rack. The ingenious design of the abutment boss 341 not only simplifies the operation process but also ensures the stability of the battery pack 10 during movement, preventing damage from collisions.

[0073] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.

[0074] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0075] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
