[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0037] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0038] like Figure 1 and Figure 2As shown, the pliers for clamping a battery in an embodiment of the present application include two clamping rods 10 and a shielding member 20. Each clamping rod 10 has a first section 11, a second section 12 and a third section 13, and the second section 12 is connected between the first section 11 and the third section 13; the first section 11 is provided with a clamping portion 111, and the third section 13 is provided with an operating portion 131. The two second sections 12 are hinged, and a space S for clamping a battery is formed between the two clamping portions 111. At least one of the two third sections 13 is provided with a shielding member 20, and the position where the third section 13 is connected to the shielding member 20 is closer to the clamping portion 111 than the operating portion 131.

[0039] It is understandable that the pliers of the embodiment of the present application are used to remove the battery that has thermal runaway and transfer the battery. For example, after the battery in the charging cabinet or storage box has thermal runaway, the pliers can be used to promptly remove the battery and transfer it to a bucket of water to extinguish the fire and prevent the further spread of the fire.

[0040] When in use, the operator applies force to the two operating parts 131 to remove the battery through the two clamping parts 111 and transfer the battery. In addition, the pliers of the embodiment of the present application are also provided with a shielding member 20, which can effectively prevent the high temperature or flame generated by the battery with thermal runaway from spreading to the operator to a certain extent, thereby protecting the operator and reducing the risk of personal injury.

[0041] Therefore, the operator can use the pliers of the embodiment of the present application to timely transfer the battery that has thermal runaway, thereby extinguishing the fire and preventing the fire from spreading further. At the same time, when the operator is clamping and transferring the battery, the shielding member 20 can protect the operator and reduce the risk of personal injury.

[0042] In one embodiment, the overall length of the pliers may be between 1000 mm and 1400 mm, such as 1000 mm, 1100 mm, 1200 mm, 1300 mm, and 1400 mm. The overall length of the pliers is between 1000 mm and 1400 mm, which can provide a safe clamping distance for the operator to avoid injury to the operator when the operator is too close to the battery when clamping the battery.

[0043] like Figure 1 and Figure 2 As shown, at least one of the two third sections 13 is provided with a hanging portion 30, which is connected to the end surface of the third section 13 away from the second section 12. When the pliers are not needed, the pliers can be hung on a wall, a side panel of a cabinet or other suitable location through the hanging portion 30, which is conducive to the storage of the pliers.

[0044] In the embodiment of the present application, the hanging portion 30 is an arc-shaped hook, and one of the two third sections 13 is provided with the hanging portion 30, while the other is not provided with the hanging portion 30. The hanging portion 30 can be connected to the end surface of the third section 13 away from the second section 12, but is not limited thereto.

[0045] Of course, in other embodiments, the hanging portion 30 may also be a belt-shaped object, and both ends of the belt-shaped object are respectively connected to the two third sections 13 .

[0046] like Figure 1 and Figure 2 As shown, the pliers further include at least three sheaths 40 , at least one sheath 40 is sheathed around the operating portion 131 of one of the two clamping rods 10 , and at least two sheaths 40 are sheathed around the operating portion 131 of the other one, and the at least two sheaths 40 are spaced apart along the axial direction of the third section 13 .

[0047] The sheath 40 may be made of insulating and heat-insulating materials, such as rubber, plastic, etc. When the operator operates the clamping rod 10, the operator may hold the sheath 40 on the operating portion 131 to prevent the operator's hand from directly contacting the operating portion 131, thereby preventing the operator from being burned by the high temperature conducted by the clamping rod 10 or accidentally getting an electric shock.

[0048] In addition, at least two spaced-apart protective covers 40 are provided on one of the third sections 13 , so that when transferring the battery, the operator can apply force to the operating portion 131 of the same third section 13 with both hands, which facilitates the operator to apply greater force.

[0049] In the embodiment of the present application, one operating portion 131 is covered with one sheath 40 , and another operating portion 131 is covered with two sheaths 40 , but the present invention is not limited thereto. For example, in other embodiments, each operating portion 131 is covered with two sheaths 40 .

[0050] like Figure 2 As shown, each clamping portion 111 has an anti-slip structure 1111 on one side facing the space S. By providing the anti-slip structure 1111, the friction between the clamping portion 111 and the battery can be increased to prevent the battery from accidentally slipping from between the two clamping portions 111 during the battery transfer process.

[0051] It can be understood that, in one embodiment, the anti-slip structure 1111 can be integrally formed on the side surface of the clamping portion 111 facing the space S, for example, the anti-slip structure 1111 is an uneven surface; in another embodiment, the anti-slip structure 1111 is a separate layer, the layer is made of anti-slip material, and is laid on the side surface of the clamping portion 111 facing the space S.

[0052] Please continue reading Figure 2At least one of the two clamping parts 111 is provided with a hook part 1112. For example, when the battery is located in a narrow space, the clamping part 111 is not convenient for clamping the battery. At this time, the battery can be hooked out and transferred by the hook part 1112. Therefore, the pliers implemented in the present application can perform both clamping and hooking actions, thereby improving the applicability of the pliers.

[0053] In the embodiment of the present application, each clamping portion 111 is provided with a hook portion 1112 .

[0054] like Figure 1 As shown, the pliers further include a collar 50, which is sleeved on the outer circumference of the two third sections 13 of the two clamping rods 10, and is used to lock the two clamping rods 10 when the pliers are in the retracted state. By providing the collar 50, the two clamping rods 10 can be prevented from accidentally opening when the pliers are not in use. On the one hand, it is more convenient to hang the pliers on the wall for storage; on the other hand, it prevents the opened clamping rods 10 from bumping against passers-by.

[0055] like Figure 1 As shown, the two second sections 12 are hinged in a cross shape, and when the pliers are in the retracted state, the two second sections 12 can form an X shape.

[0056] A second target angle α2 is formed between the axis of the first section 11 and the axis of the second section 12, and a third target angle α3 is formed between the axis of the second section 12 and the axis of the third section 13. α2 and α3 are obtuse angles, for example, α2 may be between 140° and 160°, and α3 may be between 140° and 160°.

[0057] The length of the third section 13 of each clamping rod 10 is much greater than the length of the second section 12 and much greater than the length of the first section 11, so that the pliers form a force-saving lever, which is convenient for the operator to clamp heavier batteries with less force.

[0058] like Figure 2 and Figure 3 As shown, each third section 13 is provided with a shielding member 20. Each shielding member 20 includes a baffle 21 and a fence 22, the baffle 21 is in a flat plate shape; the baffle 21 is perpendicular to the axis of the third section 13 and is connected to the third section 13; each baffle 21 has a first side 211 and a second side 212, and when the pliers are in the retracted state, the two first side 211 of the two baffles 21 are arranged face to face; the fence 22 is connected to the second side 212 of the baffle 21, and extends from the baffle 21 in a direction away from the operating portion 131 and presenting a first target angle α1 with the axis of the third section 13.

[0059] In the embodiment of the present application, the provision of the enclosure 22 can further prevent the high temperature and flame generated by the battery in thermal runaway from spreading to the operator.

[0060] It is understandable that the present application does not specifically limit the shape of the baffle 21, for example, the baffle 21 can be a semicircular plate, a rectangular plate, a triangular plate, etc. When the baffle 21 is a semicircular plate, the first side 211 is a straight side of the semicircular plate, and the second side 212 is an arcuate side of the semicircular plate; when the baffle 21 is a rectangular plate, the first side 211 is one of the sides of the rectangular plate, and the second side 212 is the remaining three sides of the rectangular plate; when the baffle 21 is a triangular plate, the first side 211 is one of the sides of the triangular plate, and the second side 212 is the remaining two sides of the triangular plate.

[0061] The enclosure 22 is connected to the second side 212 of the baffle 21 but not to the first side 211 , so as to avoid interference between the enclosures 22 of the two shielding members 20 when the pliers are in the retracted state.

[0062] In one embodiment, the first target angle α1 is an acute angle, for example, α1 may be between 30° and 60°.

[0063] like Figure 3 As shown, the baffle 21 includes a frame 213 and a transparent plate 214. The frame 213 is connected to the third section 13, and the frame 213 encloses a window 215. The outer periphery of the frame 213 has a first side edge 211 and a second side edge 212. The transparent plate 214 is made of a transparent material and is limited in the window 215. By providing the transparent plate 214, it is convenient for the operator to observe the state of the two clamping parts 111 clamping the battery through the transparent plate 214, so as to adjust the clamping force at any time.

[0064] For example, transparent materials include, but are not limited to, resin, glass, transparent aluminum, and the like.

[0065] In one embodiment, the frame 213 and the enclosure 22 are an integrated structure, but the present invention is not limited thereto.

[0066] like Figure 4 As shown, as a modified embodiment, the number of the shielding member 20 can also be one, and the shielding member 20 is connected to the third section 13 of one of the clamping rods 10. The shielding member 20 is provided with a slide groove 23, and when the pliers are switched between the retracted state and the open state, the third section 13 of the other clamping rod 10 can move along the slide groove 23.

[0067] In summary, the pliers for clamping a battery according to the embodiment of the present application have at least the following advantages and beneficial effects:

[0068] The operator can use the pliers of the embodiment of the present application to timely transfer the battery that has thermal runaway, thereby extinguishing the fire and preventing the fire from spreading further. At the same time, the shielding member 20 can protect the operator during the process of clamping and transferring the battery, reducing the risk of personal injury.
