[0002] During the battery swapping process of electric vehicles, the movement of the battery in the swapping cabinet is mainly realized by a swapping trolley. For some existing swapping trolleys, the movement of the battery is achieved by driving the battery with multiple rollers. At least two sets of roller devices need to be set up, one for longitudinal driving and one for lateral driving, and the relative height of the two sets of roller devices is adjusted according to the change of the required driving direction. The non-operating roller device descends below the operating roller device, and the roller is driven by a motor and the rotation direction of the roller is controlled to control the movement of the battery; for the other part, a battery pushing and pulling structure is arranged at the top inside the swapping trolley, and the battery is moved by the buckle of the pushing and pulling structure clamping the outer shell of the battery.

[0003] However, in the method of driving the battery by rollers, since the rollers drive the battery to move by relying on the friction with the battery, and the rotation of the rollers is stopped by using an induction device after detecting that the battery is in place. Once the induction device fails, the rollers will continuously drive the battery to move to one side, and some rollers will also have faults such as jamming, which will hinder the movement of the battery. The overall stability and reliability of the structure need to be improved.

[0004] In the method of driving the battery by a battery pushing and pulling structure, the buckle structure will have unstable performance, and there will be phenomena such as not being clamped in place or not being clamped firmly.

[0049] To better understand the purpose, structure, and function of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings. Embodiment 1

[0050] Refer to Figures 4 - 6 As shown, a two-way hook structure provided in this embodiment includes an upper sliding member 1-1 and a lower fixing member 1-2. Both the upper sliding member 1-1 and the lower fixing member 1-2 are "U"-shaped structures. The upper sliding member 1-1 with its opening facing downward is sleeved inside the lower fixing member 1-2 with its opening facing upward and is in sliding cooperation with the lower fixing member 1-2;

[0051] The length of the upper sliding member 1-1 is greater than the length of the lower fixing member 1-2;

[0052] Two long strip-shaped sliding grooves 1-8 are respectively formed on both side walls of the upper sliding member 1-1;

[0053] The two long strip-shaped sliding grooves 1-8 on one side wall of the upper sliding member 1-1 correspond to the two long strip-shaped sliding grooves 1-8 on the other side wall of the upper sliding member 1-1 in pairs;

[0054] Two rotating shafts 1-3 are penetrated through the side wall of the lower fixing member 1-2 along the direction perpendicular to the length of the lower fixing member 1-2. The two rotating shafts 1-3 are respectively located at both ends of the lower fixing member 1-2 and pass through the two long strip-shaped sliding grooves 1-8;

[0055] A left hook 1-4 and a right hook 1-5 are respectively sleeved on the two rotating shafts 1-3. The left hook 1-4 and the right hook 1-5 are arranged oppositely;

[0056] A torsion spring 1-6 is also sleeved on the rotating shaft 1-3;

[0057] The upper end face of the upper sliding member 1-1 is provided with a notch 1-7, and the left hook 1-4 and the right hook 1-5 are both located at the notch 1-7.

[0058] It should be noted that when the right end of the upper sliding member 1-1 is aligned with the right end of the lower fixing member 1-2, the left hook 1-4 extends from the notch 1-7 driven by the acting force of the torsion spring 1-6, and the right hook 1-5 is squeezed by the upper sliding member 1-1 and located below the notch 1-7; when the left end of the upper sliding member 1-1 is aligned with the left end of the lower fixing member 1-2, the right hook 1-5 extends from the notch 1-7 driven by the acting force of the torsion spring 1-6, and the left hook 1-4 is squeezed by the upper sliding member 1-1 and located below the notch 1-7.

[0059] Specifically, by changing the position of the upper sliding member 1-1 relative to the lower fixing member 1-2, the extension and retraction of the left hook 1-4 and the right hook 1-5 can be realized. The left hook 1-4 and the right hook 1-5 are arranged oppositely, and under the limiting action of the upper sliding member 1-1, the left hook 1-4 and the right hook 1-5 will not extend simultaneously, and can adapt to the two moving directions of the battery entering and exiting. Embodiment 2

[0060] Refer to Figures 1 - 7 As shown in the figure, a battery driving device provided in this embodiment includes a frame 2, a driving mechanism, and the bidirectional hook structure 1 provided in Embodiment 1;

[0061] The driving mechanism includes two sets of transmission components 3;

[0062] The two sets of transmission components 3 are symmetrically arranged at the bottom end inside the frame 2 relative to the bidirectional hook structure 1;

[0063] Each set of transmission components 3 includes a motor 3-1, a driving wheel 3-2, a driven wheel 3-3, and a conveyor belt 3-4;

[0064] The motor 3-1 is located at one end of the frame 2, and the driving wheel 3-2 is sleeved on the output shaft of the motor 3-1;

[0065] The driven wheel 3-3 is arranged at the other end of the frame 2, and the conveyor belt 3-4 is sleeved between the driving wheel 3-2 and the driven wheel 3-3;

[0066] Flanking horizontal plates 1-9 are respectively arranged on both side walls of the lower fixing member 1-2, and a belt fixing plate 1-10 is arranged at the lower end of the flanking horizontal plate 1-9;

[0067] The upper belt body of the conveyor belt 3-4 passes through between the flanking plate and the belt fixing plate 1-10, and the flanking plate and the belt fixing plate 1-10 cooperate with each other to clamp the conveyor belt 3-4;

[0068] A left baffle 3-5 is provided at a position between the two conveyor belts 3-4 close to the driving wheel 3-2, and a right baffle 3-6 is provided at a position between the two conveyor belts 3-4 close to the driven wheel 3-3. Both the left baffle 3-5 and the right baffle 3-6 correspond to the position of the upper sliding member 1-1.

[0069] Specifically, the motor 3-1 drives the driving wheel 3-2 to rotate. With the cooperation of the driving wheel 3-2 and the driven wheel 3-3, the conveyor belt 3-4 can also move, thereby driving the entire double-hook structure 1 to move. When the double-hook structure 1 hooks the groove provided at the bottom end of the battery or the side wall in the length direction of the battery, the battery also moves together with the double-hook structure 1.

[0070] Specifically, by providing the left baffle 3-5 and the right baffle 3-6, the double-hook structure 1 can be driven to collide with the left baffle 3-5 or the right baffle 3-6 under the movement of the conveyor belt, so that the upper sliding member 1-1 first collides with the left baffle 3-5 or the right baffle 3-6 to change the position of the upper sliding member 1-1 relative to the lower fixing member 1-2, realizing the extension and retraction of the left hook 1-4 or the right hook 1-5.

[0071] It should be noted that after the driving mechanism and the double-hook structure 1 cooperate with each other to move the battery to the designated position of the battery driving device, the double-hook structure 1 can move to the outside of the side end of the battery under the drive of the conveyor belt, that is, the double-hook structure 1 is not only located at the bottom of the battery, but can also move to the outside of the battery. This is to adapt to the left hook 1-4 or the right hook 1-5 being able to hook the side wall in the length direction of the battery to drag the battery, and also to ensure that the battery can smoothly move horizontally in and out of the battery driving device (that is, the battery moves along the direction perpendicular to the movement direction of the double-hook structure 1), ensuring that the left hook 1-4 or the right hook 1-5 in the double-hook structure 1 does not block the movement of the battery.

[0072] Specifically, the transmission assembly 3 further includes a slide rail 3-7;

[0073] The two slide rails 3-7 are respectively arranged on the opposite sides of the two conveyor belts 3-4 and are parallel to the conveyor belts 3-4;

[0074] A slider 1-11 is further provided at the lower end of the flank horizontal plate 1-9, and the belt fixing plate 1-10 is located between the slider 1-11 and the side wall of the lower fixing member 1-2;

[0075] The slider 1-11 is slidably engaged with the slide rail 3-7.

[0076] Specifically, by providing the slider 1-11 and the slide rail 3-7, the movement of the double-hook structure 1 can be guided, and the stability of the double-hook structure 1 during the movement is further ensured.

[0077] It should be noted that the transmission assembly 3 further includes a driving end mounting bracket 3-8 and a driven end mounting bracket 3-9;

[0078] The two motors 3-1 are arranged on the driving end mounting bracket 3-8. The output shafts of the two motors 3-1 respectively pass through the two opposite side walls of the driving end mounting bracket 3-8 and are sleeved with the driving wheels 3-2. The output shafts of the two motors 3-1 are the same shaft to achieve synchronous transmission of the motors;

[0079] A driven shaft 3-10 is arranged between the two opposite side walls of the driven end mounting bracket 3-9. The two driven wheels 3-3 are both sleeved on the driven shaft 3-10 to achieve synchronous rotation of the driven wheels.

[0080] It should be noted that the driving mechanism can also adopt a structural form of one motor 3-1, one driving wheel 3-2, one driven wheel 3-3 and one conveyor belt 3-4 to drive the bidirectional hook structure 1. Only need to adjust the two belt fixing plates 1-10 at the lower end of the wing horizontal plate 1-9 into one piece, and set the belt fixing plate 1-10 at the bottom of the lower end fixing part 1-2. In addition, arrange the two slide rails 3-7 on both sides of the conveyor belt 3-4, and keep the sliders 1-11 at the lower ends of the two wing horizontal plates 1-9, then the bidirectional hook structure 1 can be driven to move by one conveyor belt 3-4.
