Description

Technical Field

[0001] The utility model belongs to the technical field of sling grabbing technology, and in particular relates to a sling grabbing mechanism for a battery swap station. Background Art

[0002] A battery swap station is a facility that provides power battery replacement services for electric vehicles. Its main functions include centralized storage, charging and rapid replacement of batteries. A battery swap station is usually equipped with multiple power battery storage cabinets and has equipment and operating space for battery replacement. At the battery swap station, the power battery of an electric vehicle can be removed from the vehicle and charged or replaced to meet the vehicle's driving needs.

[0003] In battery swap stations, for heavier battery modules, manual handling is inconvenient and there are certain safety hazards, so a grabbing mechanism is usually used to lift the battery modules. However, the existing grabbing mechanism has relatively simple functionality during use and cannot adjust the number of grabs according to specific usage requirements. Either the grabbing mechanism can only grab one battery module at a time, or the grabbing mechanism can grab multiple battery modules at a time. In this way, two grabbing mechanisms need to be equipped during use, which not only takes up space but also needs to be disassembled and installed during use, reducing the flexibility of the grabbing mechanism during use and making the use scenario of the grabbing device relatively limited. Utility Model Content

[0004] The purpose of the present invention is to provide a grabbing mechanism for a battery swap station spreader with a simple structure and reasonable design in order to solve the above problems.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 、 Figure 2As shown, a grabbing mechanism for a battery swap station spreader includes a mounting box 1, and a mounting frame 2 installed on both sides of the mounting box 1 and located on the top of the mounting box 1. Both sides of the mounting box 1 are provided with a first grabbing mechanism that cooperates with each other, and the first grabbing mechanism includes a mounting plate 8 and two first clamping claws 9 installed at the bottom of the mounting plate 8. The interior of the mounting box 1 is rotatably connected with a bidirectional threaded rod 15, and the external threads of the bidirectional threaded rod 15 are connected to two threaded sleeves 16 sleeved in the mounting box 1. Since the threaded sleeves 16 are sleeved in the interior of the mounting box 1 and fit against the inner wall of the mounting box 1, the threaded sleeves 16 can be limited. A movable plate 7 is installed on one side of the two mounting plates 8, and one end of the two movable plates 7 extends into the interior of the mounting box 1 and is fixedly connected to one side of the two threaded sleeves 16 respectively. A rotating motor for driving the bidirectional threaded rod 15 to rotate is installed on one side of the mounting box 1.

[0024] It should be noted that this type of battery swap station hoist grasping mechanism can adjust the distance between the two first grasping mechanisms according to the width of the battery module when in use. During adjustment, the rotating motor will drive the bidirectional threaded rod 15 to rotate. At this time, the two threaded sleeves 16 threadedly connected to the outside of the bidirectional threaded rod 15 will move toward each other or away from each other. Driven by the two threaded sleeves 16, the two movable plates 7 will drive the two mounting plates 8 to move toward each other or away from each other, thereby causing the first clamping claw 9 installed at the bottom of the mounting plate 8 to move toward each other or away from each other, so that battery modules of different widths can be fixed, and only one battery module can be fixed during fixing.

[0025] Example 2

[0026] The difference between this embodiment and embodiment 1 is that two second gripping mechanisms are provided on the outside of the installation box 1 to cooperate with the two first gripping mechanisms respectively. The second gripping mechanism includes a sleeve plate 3 mounted on the outside of the installation box 1, and two second clamping jaws 6 rotatably connected to both sides of the sleeve plate 3. A fixing mechanism for fixing the second clamping jaws 6 is installed on the outside of the sleeve plate 3. The fixing mechanism includes a bracket 4, two limit blocks 5 mounted on the bottom of the bracket 4, and a limit groove 23 opened at the bottom of the limit block 5 and used in conjunction with the second clamping jaws 6. The bracket 4 is covered on the outside of the sleeve plate 3, and the two sides of the sleeve plate 3 are fixed to the second clamping jaws 6. The sides are provided with sliding components connected to the bracket 4, and both sides of the bracket 4 are provided with fixing components for fixing the bracket 4 on the sleeve plate 3. The sliding component includes a strip groove opened on one side of the sleeve plate 3, a limit rod 20 installed inside the strip groove, a limit sleeve 21 and a spring 22 sleeved on the outside of the limit rod 20, one side of the limit sleeve 21 is fixedly connected to the inner side wall of the bracket 4, and the two ends of the spring 22 are respectively fixedly connected to the bottom of the limit sleeve 21 and the inner wall of the strip groove. The fixing component includes a second bolt 18, a first fixing hole 17 opened on one side of the bracket 4, and a second fixing hole 17 opened on the side wall of the sleeve plate 3. The fixing hole 19, the first fixing hole 17 and the second fixing hole 19 are used in conjunction with the second bolt 18. Two fixing plates 10 are installed on the top of the installation box 1. The two fixing plates 10 are installed on the side close to each other with hydraulic cylinders 11. The output ends of the two hydraulic cylinders 11 are respectively fixedly connected to one side of the two sleeve plates 3. The installation box 1 is provided with a limiting mechanism for accommodating the second clamping jaw 6. The limiting mechanism includes a first bolt 13, a first threaded hole 12 opened on the outside of the installation box 1, and a second threaded hole 14 opened on the second clamping jaw 6. The first threaded hole 12 and the second threaded hole The holes 14 are used in conjunction with the first bolt 13; when a battery module needs to be grasped, the second bolt 18 screwed into the first fixing hole 17 and the second fixing hole 19 is removed. At this time, the bracket 4 will move upward under the action of the elastic force of the spring 22. At this time, the limit block 5 will separate from the second clamping jaw 6. At this time, the second clamping jaw 6 can be rotated to make the second clamping jaw 6 in a horizontal state, and then the first bolt 13 is screwed into the first threaded hole 12 and the second threaded hole 14 to fix the second clamping jaw 6, preventing the second clamping jaw 6 from interfering with the operation of the two first clamping mechanisms;

[0027] The further improved feature of this embodiment is that: when it is necessary to grab two battery modules at the same time, the first bolt 13 screwed in the first threaded hole 12 and the second threaded hole 14 is taken out, and then the second clamping jaw 6 is rotated to make the second clamping jaw 6 in a vertical state, and then the bracket 4 is pressed downward. At this time, the limiting sleeve 21 will slide on the outside of the limiting rod 20 and squeeze the spring 22 downward. When the bracket 4 is in contact with the sleeve plate 3, the limiting groove 23 will cover the outside of the second clamping jaw 6, and the second bolt 18 will be screwed into the inside of the first fixing hole 17 and the second fixing hole 19 to fix the bracket 4 to the sleeve plate 3, preventing the bracket 4 from being moved during the operation. During the grabbing operation, the second jaw 6 moves. At this time, the adjacent first jaw 9 and the second jaw 6 are used in conjunction to place the battery module between the first jaw 9 and the second jaw 6. At this time, the hydraulic cylinder 11 and the rotating motor will work. At this time, the first jaw 9 will move toward the side close to the second jaw 6. The hydraulic cylinder 11 will drive the sleeve plate 3 to move outside the installation box 1, so that the second jaw 6 moves toward the side close to the first jaw 9, thereby fixing the battery module between the first jaw 9 and the second jaw 6. In this way, two battery modules can be grabbed at one time, thereby improving the flexibility of the device.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
