It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] The traditional battery module hoist usually consists of a main beam and a hook arranged on the main beam. The problem is that the length of the main beam is fixed, and there is a risk of unhooking when hoisting a battery module that does not match the length of the main beam. In this regard, the prior art provides a hoist for a battery module, wherein two movable rods are respectively installed on both sides of the support rod, and a connecting seat is provided at one end of any movable rod extending out of the support rod, and the connecting seat is provided with a fixed component for connecting the battery module. The two movable rods are respectively extended and retracted along the length direction of the support rod, thereby changing the total length of the support rod and the movable rod, and then changing the distance between the two fixed components to achieve the hoisting of battery modules of different lengths. However, the problem is that the connecting seat is fixedly arranged on the movable rod, resulting in the need to continuously adjust the relative positions of the two fixed components through the movable rod during the installation of the battery module so that the battery module can be stably installed on the fixed component, which is inconvenient to operate.

[0039] In view of the above problems, this embodiment provides a battery module hanger to solve the problem that the hanger in the prior art needs to continuously adjust the relative positions of the two fixed components through a movable rod during the installation of the battery module, which is inconvenient to operate. The hanger can be used in the field of hanger technology.

[0040] Reference Figure 1-Figure 3 The battery module hoist is used to lift the battery module 10, and specifically includes a main beam 1, a telescopic beam 2 and a hook assembly 3. Two telescopic beams 2 are provided, and the two telescopic beams 2 are respectively provided at both ends of the main beam 1, and both can be telescoped relative to the main beam 1 along the length direction of the main beam 1, so as to adjust the total length of the main beam 1 and the telescopic beam 2. Two hook assemblies 3 are provided, and the two hook assemblies 3 are connected to the two telescopic beams 2 in a one-to-one correspondence. The hook assembly 3 includes a hook connector 31 rotatably provided on the telescopic beam 2 and a hook 32 provided on the hook connector 31. The hook 32 is used to install the battery module 10, so as to lift the battery module 10. Optionally, the hook 32 can directly install the battery module 10 for lifting, and when the battery module 10 is a long module, a lifting belt can also be installed on the hook 32, and the lifting belt is connected to the battery module 10 to prevent the battery module 10 from tilting. In the battery module hanger, the total length of the main beam 1 and the telescopic beam 2 is adjustable, so as to adapt to battery modules 10 of different lengths. In addition, the hook connector 31 is rotatably arranged on the telescopic beam 2. During the installation of the battery module 10, the installation between the hooks 32 at both ends and the battery module 10 can be quickly completed by rotating the hook connector 31, which is convenient for operation.

[0041] Continue to refer to Figure 1-Figure 3, the extension of the two telescopic beams 2 relative to the main beam 1 is always equal, so as to keep the center of the battery module hoist stable during the lifting process and avoid the battery module 10 from tilting during the lifting process. Optionally, the main beam 1 is provided with two receiving grooves along its length direction, and the two telescopic beams 2 are respectively arranged in the two receiving grooves of the main beam 1, so that the main beam 1 can provide certain protection for the telescopic beam 2 to avoid damage to the telescopic beam 2.

[0042] Specifically, both telescopic beams 2 are provided with racks, and the main beam 1 is rotatably provided with gears, which mesh with the two racks at the same time, so that the two racks can be driven to move at the same time by rotating the gears, thereby driving the two telescopic beams 2 to move, and during the movement, the extension amount of the two telescopic beams 2 relative to the main beam 1 is always equal.

[0043] As an alternative solution, two cylinders can be provided, with the fixed ends of the two cylinders being provided on the main beam 1, and the telescopic ends of the two cylinders being connected to the two telescopic beams 2 respectively, and the two cylinders being configured to move synchronously so that the movement amounts of the telescopic ends of the two cylinders relative to the fixed ends are the same, thereby ensuring that the extension amounts of the two telescopic beams 2 relative to the main beam 1 are equal.

[0044] Continue to refer to Figure 1-Figure 3 The battery module hanger also includes a limiter 4. The telescopic beam 2 can be extended relative to the main beam 1 and has a maximum extension position. When the telescopic beam 2 is at the maximum extension position, the limiter 4 abuts against the telescopic beam 2 along the length direction of the main beam 1 to prevent the telescopic beam 2 from extending relative to the main beam 1, thereby limiting the movement of the telescopic beam 2 when the telescopic beam 2 moves to the maximum extension position to prevent the telescopic beam 2 from moving excessively. Among them, one or two limiters 4 can be set. It can be understood that since the extension amount of the two telescopic beams 2 relative to the main beam 1 is always equal, limiting one of the telescopic beams 2 can simultaneously prevent the movement of the two telescopic beams 2. In order to improve the limiting effect, two limiters 4 can be set. When any telescopic beam 2 is at the maximum extension position, the two limiters 4 abut against the two telescopic beams 2 respectively.

[0045] Continue to refer to Figure 1-Figure 3 The telescopic beam 2 is provided with a groove 21 extending along the length direction of the main beam 1, and the stopper 4 is slidably arranged in the groove 21. When the telescopic beam 2 is at the maximum extension position, the stopper 4 abuts against the groove wall of the groove 21, so that the telescopic beam 2 is limited by the cooperation of the stopper 4 and the groove wall of the groove 21, thereby preventing the telescopic beam 2 from moving excessively. In addition, the structure of the telescopic beam 2 can be simplified by the groove.

[0046] Continue to refer to Figure 1-Figure 3The battery module hoist also includes a locking member 5, which is used to lock or unlock the relative position of the telescopic beam 2 and the main beam 1, so that when the extension amount of the telescopic beam 2 relative to the main beam 1 is adjusted, the relative position of the two can be locked by the locking member 5, so as to avoid the movement of the telescopic beam 2 relative to the main beam 1 during the hoisting process, resulting in the problem of unstable hoisting. When it is necessary to adjust the extension amount of the telescopic beam 2 relative to the main beam 1, the two can be unlocked by the locking member 5. In this embodiment, the locking member 5 is a locking screw threadedly connected to the main beam 1, which passes through the main beam 1 and can be pressed against or separated from one of the telescopic beams 2, thereby completing the locking or unlocking of the telescopic beam 2.

[0047] Continue to refer to Figure 1-Figure 3 The telescopic beam 2 is rotatably connected to the hook assembly 3 via a pin 6, and the pin 6 is connected to a retaining spring, which is used to prevent the pin 6 from moving along the axial direction of the pin 6 relative to the telescopic beam 2, thereby preventing the pin 6 from coming out along the axial direction thereof. Optionally, the hook connector 31 is provided with two connecting plates 311, which are respectively provided on both sides of the telescopic beam 2, and the two connecting plates 311 are respectively abutted against the side walls of the telescopic beam 2, and the pin 6 passes through one of the connecting plates 311, the telescopic beam 2, and the other connecting plate 311 in sequence, so that only the hook connector 31 is allowed to rotate relative to the telescopic beam 2, and the hook connector 31 is prevented from falling off, so that the hook connector 31 can be stably installed on the telescopic beam 2.

[0048] Continue to refer to Figure 1-Figure 3 The hook 32 is J-shaped and includes a connecting end 321, an extension section 322 and a lifting end 323 which are connected in sequence. The connecting end 321 is connected to the hook connector 31, and the lifting end 323 is used to install the battery module 10. The connecting end 321 and the lifting end 323 are located on the same side of the extension section 322, so as to facilitate the installation of the battery module 10 and stabilize the connection between the hook 32 and the battery module 10 to prevent the battery module 10 from falling.

[0049] Continue to refer to Figure 1-Figure 3 Any hook assembly 3 includes two hooks 32 to increase stability during lifting. In addition, the hook assembly 3 also includes a reinforcing rod 33 that connects the two hooks 32 at the same time. The reinforcing rod 33 can strengthen the structural strength between the two hooks 32.

[0050] Continue to refer to Figure 1-Figure 3 The main beam 1 is provided with two lifting rings 7, which are respectively located at the two end portions of the main beam 1 along the length direction, to replace the solution of only providing a lifting ring at the center position of the main beam 1 in the prior art, and can ensure that a balanced state is maintained when hoisting a battery module 10 with a long length, and avoid tilting of the battery module 10 due to uneven force.

[0051] Continue to refer to Figure 1-Figure 3In the actual hoisting process, the lower end of the main beam 1 may collide with the battery module 10 due to careless operation. In this regard, an anti-collision strip 8 is provided at the lower end of the main beam 1. The anti-collision strip 8 can provide a buffer for the collision between the lower end of the main beam 1 and the battery module 10 to protect the main beam 1 and the battery module 10. Optionally, the anti-collision strip 8 is made of insulating material to increase safety.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
