[0035] One of the core components of electric vehicles is the battery pack. A battery pack is a single unit assembled from multiple battery modules, used to store and deliver electrical energy. It is a higher-level component in the battery system, typically consisting of several battery modules, connectors, a battery management system, a cooling system, electrical interfaces, and a housing.

[0036] Battery packs often encounter the following emergency situations during manufacturing: thermal runaway, explosion, fire, and gas leaks. These situations necessitate relocation of the battery pack. However, due to the cumbersome operation of hoists, operators typically use clamps to relocate battery packs in critical situations. However, existing clamps lack adjustable clamping spacing, making them incapable of handling battery packs of varying sizes.

[0037] To address the above-mentioned issues, the disclosed embodiments provide an emergency clamp with adjustable clamping distance. By bringing the operating ends of the two force-applying rods closer together, the clamping ends of the two force-applying rods are brought closer together, driving the two clamping members to clamp the battery pack to be transferred. An angle limiting mechanism can change and limit the angle between the clamping members and the clamping rods, allowing the two clamping members to clamp battery packs of different sizes while also maintaining the clamping members in a vertical clamping position, thereby improving the clamping effect on the battery pack.

[0038] Figure 1 The figure shows the overall structure of the emergency clamp with adjustable clamping distance in the embodiment of the present disclosure. Figure 1In the example, the emergency clamp with adjustable clamping spacing includes a pair of force rods 10, a pair of clamping members 20, and an angle limiting mechanism 30. The middle portions of the pair of force rods 10 are hinged. The pair of clamping members 20 are respectively hinged to the clamping ends 11 of the two force rods 10 so that the angle between them and the hinged force rods 10 is adjustable. The angle limiting mechanism 30 is provided between each of the clamping members 20 and the force rod 10 to which it is hinged, and fixes the relative position between the clamping members 20 and the force rod 10 to limit the angle, so that the pair of clamping members 20 can maintain a vertical state and clamp objects of different sizes.

[0039] The advantage of this arrangement is that by bringing the operating ends of the two force-applying rods 10 closer together, the clamping ends 11 of the two force-applying rods 10 are brought closer together, driving the two clamping members 20 to clamp the battery pack to be transferred. The angle limiting mechanism 30 can change and limit the angle between the clamping members 20 and the clamping rods, allowing the two clamping members 20 to clamp battery packs of different sizes while also maintaining the clamping members 20 in a vertical clamping position, thereby improving the clamping effect of the clamping members 20 on the battery pack.

[0040] Figure 2 The embodiment of the present disclosure is shown in Figure 1 Schematic cross-sectional view of AA. Figure 3 , a cross-sectional view of an emergency clamp with adjustable clamping distance according to an embodiment of the present disclosure is shown. For example, the angle limiting mechanism 30 includes a plurality of adjustment portions 31 corresponding to different relative positions between the clamping member 20 and the force rod 10, and a snap-fitting member 32 for snapping into one of the adjustment portions 31; one of the force rod 10 and the clamping member 20 forms the plurality of adjustment portions 31, and the other is provided with the snap-fitting member 32. Figure 2 and Figure 3 In the example, the clamping end 11 of the force application rod 10 is hinged to the clamping member 20 via a hinge shaft. The clamping end 11 of the force application rod 10 forms the multiple adjustment portions 31 spaced apart along the circumference of the hinge shaft, and the engaging member 32 is passed through the clamping member 20. A through hole (not shown in the figure) is formed on the clamping member 20 for the engaging member 32 to pass through. Exemplarily, the adjustment portion 31 is implemented as an adjustment hole, and the engaging member 32 is implemented as a engaging rod. Further exemplarily, the adjustment hole is adapted to the size of the engaging rod to reduce the gap between the adjustment portion 31 and the engaging member 32.

[0041] Those skilled in the art will appreciate that when a battery pack of a certain length needs to be clamped, the operator first disengages the engaging member 32 from the adjusting portion 31. After the two clamping members 20 have clamped the battery pack of that length and are in a vertical position, the operator reengages the engaging member 32 with the adjusting portion 31 at the corresponding position to define the angle between the clamping member 20 and the operating rod. This operation allows the two clamping members 20 to maintain a vertical clamping position when clamping battery packs of different sizes, thereby improving the clamping effect of the clamping members 20 on the battery pack.

[0042] For example, the engaging member 32 can maintain a state of being engaged with the adjusting portion 31. Figure 2 In this example, the engaging member 32 is threadedly engaged with the adjusting portion 31. For example, an inner wall of the adjusting portion 31, which is implemented as an adjusting hole, is formed with an internal thread (not shown in the figure), and an outer edge surface of the engaging member, which is implemented as the engaging rod, is formed with an external thread (not shown in the figure) that is threadedly engaged with the internal thread.

[0043] Figure 4 The embodiment of the present disclosure is shown in Figure 1 A cross-sectional view of another embodiment of AA is shown in FIG. Figure 4 In this example, the emergency clamp with adjustable clamping distance further includes an elastic member 33, whose ends are respectively connected to the engaging member 32A and the clamping member 20 or the force-applying rod on which the engaging member 32A is mounted. In this embodiment, the elastic member 33 is implemented as a spring, with one end connected to the side wall of the clamping member 20 and the other end connected to the side wall of the engaging member 32A. This ensures that the engaging member 32A remains engaged with the adjusting portion 31A under the elastic force of the elastic member 33.

[0044] In another embodiment, the clamping member forms the plurality of adjustment portions spaced apart along the circumference of the hinge shaft, and the engaging member is provided on the force application rod.

[0045] In another embodiment, the angle limiting mechanism is implemented as a telescopic member, one end of which is hinged to the force application rod and the other end is hinged to the clamping member. It is understood that the angle between the clamping member and the force application rod can be adjusted by changing the length of the telescopic member. Exemplarily, the telescopic member is implemented as a pneumatic cylinder or an oil cylinder.

[0046] Back to Figure 1In this example, the emergency clamp with adjustable clamping distance further includes a locking mechanism 40, disposed between the pair of force application rods 10, to lock the angle between the pair of clamping ends 11. The locking mechanism 40 includes a locking member 41 and a plurality of mating portions 42. One of the force application rods 10 is provided with at least one mating portion 42, and the other force application rod 10 is provided with at least two mating portions 42. The locking member 41 includes a first locking portion 411 and a second locking portion 412, which are respectively locked with one mating portion 42 on each of the pair of force application rods 10.

[0047] Figure 5 The embodiment of the present disclosure is shown in Figure 1 Schematic cross-sectional view of the BB. Figure 6 The embodiment of the present disclosure is shown in Figure 1 A cross-sectional view of another state of BB. Figure 1 、 Figure 5 and Figure 6 In this example, the pair of force application rods 10 are provided as a first force application rod 10A and a second force application rod 10B. The first force application rod 10A forms one mating portion 42, while the second force application rod 10B forms multiple mating portions 42 spaced apart along its length. The first locking portion 411 of the locking member 41 engages with the mating portion 42 on the first force application rod 10A, and the second locking portion 412 engages with one of the mating portions 42 on the second force application rod 10B.

[0048] It will be understood by those skilled in the art that the initial state is Figure 6 As shown, the first locking portion 411 of the locking member 41 is engaged with the matching portion 42 on the first force rod 10A, and the second locking portion 412 is not engaged with the matching portion 42 on the second force rod 10B. After the two clamping members 20 clamp the battery pack and the angle between them and the force rod 10 is limited, the operator moves the locking member 41 to the position of the second limiting portion 412 corresponding to one of the matching portions 42 on the second force rod 10B, and then pushes the locking member 41 to the second limiting portion 412 to lock and engage with the matching portion 42 (as shown in FIG. Figure 5 As shown). In this way, the first force applying rod 10A, the first force applying rod 10B, and the locking member 41 form a "triangle". The stability of the triangle ensures that when two operators lift the sling and transfer it, the angle between the pair of clamping ends 11 will not change due to inconsistent steps of the two operators, thereby ensuring the clamping effect of the clamp on the battery pack and preventing the battery pack from falling off the clamp.

[0049] Exemplarily, the force rod 10 is implemented as a circular tube, and the mating portion 42 is implemented as two fixing holes formed in the outer wall of the circular tube along the radial direction of the circular tube. Further exemplarily, the fixing holes are sized to match the first locking portion 411 and the second locking portion 412 to prevent the two force rods 10 from loosening due to excessive gaps between the fixing holes and the first locking portion 411 and the second locking portion 412.

[0050] exist Figure 5 and Figure 6 In this example, an anti-dropout portion 413 is provided at the end of the first locking portion 411 of the locking member 41. The anti-dropout portion 413 can prevent the locking member 41 from falling off the force application rod 10 when the second limiting portion 412 of the locking member 41 is not engaged with the matching portion 42.

[0051] In another embodiment, a plurality of adjustment portions are formed on each of the first force applying rod and the second force applying rod, thereby further increasing the range of the angle between the pair of clamping ends locked by the locking mechanism and further improving the applicability of the clamp.

[0052] Figure 7 The figure shows the overall structure of the clamping member in the embodiment of the present disclosure. Figure 3 and Figure 7 In the example, the clamping member 20 includes: a clamping plate 21 for clamping against the object to be clamped, a plurality of penetration portions 211 corresponding to different positioning positions formed on the clamping plate 21, and a positioning member 22 that can be detachably provided on the plurality of penetration portions 211 and can be switched between the plurality of penetration portions 211, and the positioning member 22 is combined with the positioning portion on the object to be clamped to position the object to be clamped. It will be understood by those skilled in the art that by changing the different clamping positions of the positioning member 22 on the clamping plate 21 to adapt to battery packs with different positioning portion positions on the clamped end surface, the clamping effect of the clamping member 20 is further improved.

[0053] For example, the plurality of penetration portions 211 are threadedly connected to the positioning member 22. For example, the shape and size of the penetration portion 211 can be adjusted according to actual needs. In another embodiment, the plurality of penetration portions are plug-connected to the positioning member.

[0054] Back to Figure 1 In this example, the other end of each force-applying rod 10 away from the clamping end 11 is an operating end 12, and the operating end 12 is covered with an insulating sleeve 121. The provision of the insulating sleeve 121 can prevent the operator from being injured by battery pack leakage, thereby improving the safety factor of the operator.

[0055] In summary, an embodiment of the present disclosure provides an emergency clamp with adjustable clamping spacing, comprising a pair of force-applying rods, a pair of clamping members, and an angle limiting mechanism. The pair of force-applying rods are hinged at their midpoints. The pair of clamping members are respectively hinged to the clamping ends of the two force-applying rods, so that the angle between them and the hinged force-applying rods is adjustable. The angle limiting mechanism is disposed between each clamping member and the force-applying rod to which it is hinged, fixing the relative position between the clamping member and the force-applying rod to define the angle, so that the pair of clamping members can maintain a vertical position and clamp objects of different sizes. By bringing the operating ends of the two force-applying rods closer together, the clamping ends of the two force-applying rods are brought closer together, driving the two clamping members to clamp the battery pack to be transferred. The angle limiting mechanism can change and limit the angle between the clamping member and the clamping rod, so that the two clamping members can maintain a vertical position when clamping battery packs of different sizes, thereby improving the clamping effect of the clamping members on the battery pack.

[0056] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, any equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be encompassed by the scope of protection of this disclosure.
