[0034] Combine the following Figures 1 to 5 The battery module clamping structure 10 provided in this embodiment is described in detail.

[0035] Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides a battery module clamp structure 10, including a hollow cylinder 200, a movable shaft 300 and at least two clamps 400. The side wall of the hollow cylinder 200 is provided with at least two openings 210 along the circumferential direction, and the hollow cylinder 200 is used to extend into the module shell hole 110; the movable shaft 300 is axially slidably arranged in the hollow cylinder 200; at least two clamps 400 are respectively arranged between the movable shaft 300 and the outer wall of the hollow cylinder 200 along the circumferential direction, and the at least two clamps 400 correspond to the positions of the at least two openings 210 respectively; the at least two clamps 400 are used to approach each other during the axial sliding process of the movable shaft 300 to retreat into the opening 210, or to move away from each other to protrude from the opening 210, thereby supporting the module shell hole 110.

[0036] One end of the hollow cylinder 200 is for the movable shaft 300 to extend into, and the other end of the hollow cylinder 200 can be closed or not. In this embodiment, the other end of the hollow cylinder 200 is closed, which can prevent foreign debris from entering the hollow cylinder 200 on the one hand, and can also limit the axial movement of the movable shaft 300 on the other hand, preventing the movable shaft 300 from extending out of the hollow cylinder 200 from the other end. The number of the clamping jaws 400 is at least two, and the clamping jaws 400 can be set to two, three or four. At least two clamping jaws 400 are arranged in the hollow cylinder 200 around the outer circumference of the movable shaft 300, and the movable shaft 300 slides in the axial direction, which can push the clamping jaws 400 to move closer to or away from each other, thereby adjusting the diameter size surrounded by the clamping jaws 400 to achieve the effect of exiting the module shell hole 110 and being stuck in the module shell hole 110. The opening 210 provided on the hollow cylinder 200 is used to limit the position of the clamping jaw 400 , and at the same time allows the clamping jaw 400 to protrude outward to press against the module housing hole 110 .

[0037] The cylindrical design of the hollow cylinder 200 can be inserted into the module housing hole 110, and there are two to three groups of protruding jaws 400 inside it. The jaws 400 fit with the movable shaft 300. The movable shaft 300 is in the hollow cylinder 200. When the movable shaft 300 rises, the jaws 400 will be driven by the movable shaft 300 to rise due to the unique design, and will also extend outward from the opening 210, squeeze the module housing hole 110, and firmly lock with the module 100, so that the module 100 can be moved; the movable shaft 300 drops, thereby driving the jaws 400 to return. In other embodiments, the movable shaft 300 can also rise, the jaws 400 return, the movable shaft 300 drops, and the jaws 400 extend outward, which is specifically set according to the matching situation of the movable shaft 300 and the jaws 400.

[0038] Reference Figure 1 and Figure 2 In this embodiment, a tapered portion 310 is formed at one end of the movable shaft 300; the tapered portion 310 is used to slide with at least two clamping jaws 400 to push at least two clamping jaws 400 away from or closer to each other.

[0039] The diameter of the tapered portion 310 gradually increases from one end to the other end. During the sliding cooperation between the clamping jaw 400 and the tapered portion 310, the clamping jaw 400 gradually moves away to extend out of the opening 210, or gradually moves closer to return to its original position. In this embodiment, the diameter of the tapered portion 310 gradually increases from the open end to the closed end of the hollow cylinder 200. Figure 1 and Figure 2 The relative position in FIG. 2 is introduced, and the diameter of the tapered portion 310 gradually increases from top to bottom.

[0040] Reference Figure 1 and Figure 2 In this embodiment, a threaded portion 421 is provided on one side of the clamping jaw 400 facing the opening 210 ; the threaded portion 421 is used to be located in the opening 210 during the sliding process of the movable shaft 300 , or to protrude from the opening 210 and abut against the module housing hole 110 .

[0041] The threaded portion 421 can increase the friction between the clamping jaw 400 and the module shell hole 110, so that when the clamping jaw 400 is expanded outward to press against the module shell hole 110, the battery module clamping jaw structure 10 and the module shell hole 110 can be firmly clamped, making it easier to lift or move the module 100.

[0042] When the clamping jaw 400 is not unfolded, the threaded portion 421 is located in the opening 210, and the circumferential movement of the threaded portion 421 and the entire clamping jaw 400 can be limited by the side wall of the opening 210, thereby preventing the clamping jaw 400 from moving circumferentially along the hollow cylinder 200. Specifically, the bottom end of the clamping jaw 400 has a blocking piece, which can be inserted into the inner wall of the hollow cylinder 200 to prevent the clamping jaw 400 from running out of the opening 210 and to limit the clamping jaw 400 along the radial direction of the hollow cylinder 200.

[0043] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the battery module clamp structure 10 also includes a fixing seat 500 and a fixing plate 600; the fixing plate 600 is provided with a mounting hole 610, the hollow cylinder 200 is fixed to the fixing plate 600, and the hollow cylinder 200 is coaxially arranged with the mounting hole 610; the fixing plate 600 is fixed to the fixing seat 500, and the movable shaft 300 is slidably arranged in the mounting hole 610 and the hollow cylinder 200 at the same time. The fixing seat 500 is fixed to the fixing seat 500 through the fixing plate 600, the movable shaft 300 is slidably arranged on the fixing seat 500, and the movable shaft 300 is movably arranged through the mounting hole 610. The fixing seat 500 and the fixing plate 600 are used for structural installation. Specifically, the fixing seat 500 is rectangular and the fixing plate 600 is circular.

[0044] Specifically, the fixing seat 500 includes an upper fixing seat and a lower fixing seat, the upper fixing seat and the lower fixing seat are fixed, the upper fixing seat is provided with a mounting cavity, and the lower fixing seat is provided with a mounting groove.

[0045] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the fixing seat 500 is provided with a mounting groove 510, the fixing plate 600 seals the mounting groove 510, and the mounting hole 610 corresponds to the mounting groove 510; the clamping jaw 400 includes a transverse portion 410 and a vertical portion 420 arranged at an angle; the vertical portion 420 is arranged between the movable shaft 300 and the outer wall of the hollow cylinder 200, and the transverse portion 410 moves through the mounting hole 610 and is located in the mounting groove 510. Specifically, a threaded portion 421 is arranged on the side of the vertical portion 420 facing the opening 210.

[0046] The transverse portion 410 of the clamping jaw 400 is installed in the installation groove 510, and the installation hole 610 of the fixing plate 600 passes through the vertical portion 420 of the clamping jaw 400 and is fixed to the fixing seat 500, and seals the installation groove 510. The transverse portion 410 is blocked by the fixing plate 600 and will not exit the installation groove 510, so that the clamping jaw 400 is installed. When pushed by the movable shaft 300, the clamping jaw 400 moves as a whole along the radial direction of the installation hole 610 to approach or move away from each other.

[0047] In this embodiment, the battery module clamp structure 10 also includes a first spring 700 ; the first spring 700 is disposed between the bottom of the mounting groove 510 and the transverse portion 410 of the clamp 400 , and the first spring 700 has a movement tendency to push the transverse portion 410 to move toward the hollow cylinder 200 .

[0048] by Figure 1The relative position in the figure is introduced, the first spring 700 is flexible and will not affect the radial movement of the clamping jaws 400 along the mounting hole 610, that is, it will not affect the clamping jaws 400 moving away from and close to each other in the lateral direction. Because the first spring 700 has a movement tendency to move the clamping jaws 400 downward, it can reduce the distance that the clamping jaws 400 move upward. When the movable shaft 300 moves upward, it will drive the clamping jaws 400 to move upward and outward, so that the movable shaft 300 can normally drive multiple clamping jaws 400 to move closer to and away from each other.

[0049] Reference Figure 1 and Figure 2 In this embodiment, the fixed seat 500 is also provided with an installation cavity 520; a movable plug 320 is formed at one end of the movable shaft 300, and the movable plug 320 is slidably arranged in the installation cavity 520 along the axial direction of the movable shaft 300; the middle part of the movable shaft 300 moves through the installation groove 510 and the installation hole 610.

[0050] The movable plug 320 is disposed in the installation cavity 520, and various driving mechanisms can be used to drive the movable plug 320 to move. The installation cavity 520 limits the movement of the movable plug 320 to prevent the movable shaft 300 from moving in an oblique manner.

[0051] Reference Figure 1 and Figure 2 In this embodiment, the movable plug 320 divides the installation cavity 520 into an upper chamber 521 and a lower chamber 522; the fixed seat 500 is provided with a release air supply port 530 connected to the upper chamber 521 and a clamping air supply port 540 connected to the lower chamber 522; the clamping air supply port 540 and the release air supply port 530 are used to alternately supply gas to push the movable plug 320 to reciprocate in the installation cavity 520, so as to push the movable shaft 300 to slide axially.

[0052] Reference Figure 1 , the air supply port 540 is clamped to allow air to enter, pushing the movable plug 320 upward, the entire movable shaft 300 upward, the tapered portion 310 pushing the clamping jaw 400 outward and upward, compressing the first spring 700 to achieve locking with the hole; refer to Figure 2 , the air supply port 530 is released to allow air to enter, pushing the movable plug 320 downward, the entire movable shaft 300 downward, the tapered portion 310 downward, and the clamping jaw 400 returning to its original position. By alternately supplying air to the upper chamber 521 and the lower chamber 522 through the release air supply port 530 and the clamping air supply port 540, the movable plug 320 can be reciprocated up and down.

[0053] Reference Figure 1 and Figure 2In this embodiment, the battery module clamping structure 10 also includes a second spring 710; the second spring 710 is arranged in the upper chamber 521, and the second spring 710 is supported between the top wall of the upper chamber 521 and the movable plug 320, and the second spring 710 has a movement tendency for pushing the movable plug 320 to move toward the hollow cylinder 200.

[0054] The second spring 710 has a movement tendency for moving the movable plug 320 downward. When neither the clamping air supply port 540 nor the releasing air supply port 530 supplies air, the second spring 710 drives the movable plug 320 to move downward, causing the conical portion 310 to move downward, thereby resetting the clamping jaw 400 back into the opening 210 and disengaging from the module housing hole 110.

[0055] According to a battery module clamp structure 10 provided in this embodiment, the working principle of the battery module clamp structure 10 is:

[0056] The hollow cylinder 200 is a cylindrical design that can be inserted into the module shell hole 110. There are two to three groups of extendable jaws 400 inside it. The jaws 400 are fitted with the movable shaft 300. The movable shaft 300 is located in the closed hollow cylinder 200. When air pressure is input into the clamping air supply port 540, the movable shaft 300 rises. The jaws 400 will be driven up by the movable shaft 300 due to its unique design and will also extend outward to squeeze the inner wall of the module shell hole 110, thereby firmly locking the module 100. When the air pressure of the clamping air supply port 540 is withdrawn and air pressure is input into the release air supply port 530, the movable shaft 300 descends, thereby driving the jaws 400 to return to their original position.

[0057] 2. The robot 21 moves the transport module 100 to the designated area, slowly descends until the module 100 is placed stably, withdraws the air pressure from the clamping air supply port 540, releases the air pressure input from the air supply port 530, and the clamping jaw 400 returns to its original position and separates from the module 100. The robot 21 then slowly lifts the clamping jaw 400 out of the hole in the shell. The robot 21 returns to its original position and the entire module 100 transport movement is completed.

[0058] The battery module clamp structure 10 provided in this embodiment has at least the following advantages:

[0059] The hollow cylinder 200 can be inserted into the module housing hole 110, and the movable shaft 300 moves to push the clamping claw 400 to extend out of the opening 210, squeeze the module housing hole 110, and lock with the module 100, so as to realize the transportation of the module 100; the movable shaft 300 moves in the opposite direction, the clamping claw 400 resets, and withdraws from the module housing hole 110, so as to complete the transportation of the module 100. The structure is more compact, and the clamping and releasing actions of the clamping claw 400 only occupy one surface of the module 100, with less interference with the surrounding of the module 100; the clamping action is fast, and the clamping and releasing actions of the module 100 can be quickly realized, reducing the operation time.

[0060] Reference Figure 4 and Figure 5 The embodiment of the utility model further provides a battery module handling device 20. The battery module handling device 20 includes a robot 21, a handling tool 22 and at least one battery module clamping structure 10, the handling tool 22 is connected to the robot 21, and the battery module clamping structure 10 is fixed on the handling tool 22.

[0061] Two or four battery module clamp structures 10 are fixed on a handling tool 22, and the handling tool 22 is installed on a robot 21. When the module 100 arrives at the workstation, the robot 21 moves the tool to accurately place the clamp 400 in the module shell hole 110 through the positioning system. The clamping air supply port 540 inputs air pressure, and the clamp 400 extends out to squeeze the inner wall of the module shell hole 110, thereby firmly locking the module 100. The battery module handling device 20 can realize automatic module 100 handling without manual intervention.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
