Description

Technical Field

[0001] This invention relates to the field of battery rack installation technology, specifically to a floating claw-type locking hook for locking battery racks. Background Technology

[0002] For heavy-duty trucks with automatic battery swapping, a locking mechanism is needed to lock the battery rack (battery system assembly) to the vehicle base. When the battery needs to be replaced, the locking mechanism is unlocked, and then a fully charged battery can be replaced. Currently used locking mechanisms mainly include wedge block push locking mechanism, flat integrated locking hook, flat hinge locking hook, and arc hinge locking hook.

[0003] However, all of these methods have certain drawbacks in their use, for example:

[0004] 1. Wedge-shaped block push-locking mechanism: Poor tolerance to manufacturing errors, prone to jamming after clamping, resulting in inability to unlock; 2. Planar integrated lock hook: Poor tolerance to manufacturing errors, prone to jamming after clamping, resulting in inability to unlock; 3. Planar hinge lock hook: Improved tolerance to manufacturing errors, but jamming still occurs, resulting in inability to unlock; 4. Arc-faced hinge lock hook: The hinged part must participate in movement and bear the locking force; high precision requirements for components, complex structure, and high processing and manufacturing costs. Therefore, there is an urgent need to design a floating claw lock hook for battery rack locking to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a floating claw-type locking hook for locking battery holders, so as to solve the problems mentioned in the background art.

The limiting block 11 is fixedly installed on the connecting plate 10 by bolts. At the front end, the two ends of the rotating adjusting column 12 are rotatably engaged between the middle of the limiting block 11. The bottom inner side of the rotating adjusting column 12 is fixedly installed with the connecting drive arm 13, and the connecting shaft 15 is rotatably inserted into the bottom of the connecting drive arm 13. The fixed chuck 18 is evenly secured to the rotating adjusting column 12 by bolts. The upper part of the outer end of the fixed chuck 18 is fixedly connected with a floating claw 8. The battery rack lock uses a floating claw 8 type lock hook. The working surface of the horizontal pressure plate 9 connected to the upper end of the floating claw 8 adopts an arc structure design. In actual use, the locking and unlocking operations are smooth and there will be no jamming. It is more convenient to use. The battery rack lock uses a floating claw 8 type lock hook. The floating claw 8 and the horizontal pressure plate 9 are connected by a pin shaft. In actual processing and manufacturing, the tolerance is strong, which reduces the difficulty of processing. The floating claw 8 bears the main locking force, and the moving parts do not bear the locking force, which improves the service life of the parts. The structure is simple and reduces the manufacturing cost.

[0033] The upper bottom of the floating claw 8 is rotatably connected to a horizontal pressure plate 9 via a pin 7, making it easy to replace the horizontal pressure plate 9.

[0034] The fixing column 14 is fixedly installed inside the mounting frame 3 by bolts.

[0038] Two floating claws 8 and a horizontal pressure plate 9 are distributed on the upper part of each end of the battery 2, so that the floating claws 8 and the horizontal pressure plate 9 can press and fix the four corners of the upper end of the battery 2, making the battery 2 firmly fixed. Specific Implementation Example 2

[0040] A floating claw-type locking hook for battery rack locking includes an electrical device 1, a battery 2, a mounting frame 3, a fixing connecting plate 4, and placement slots 5. The electrical device 1 is fixedly mounted on the upper end of the mounting frame 3 by bolts. The fixing connecting plate 4 is fixedly connected to the bottom end of the mounting frame 3. Placement slots 5 are evenly distributed inside the mounting frame 3. The battery 2 is fixedly placed inside the placement slots 5. An adjustment and control device 6 is fixedly mounted inside the mounting frame 3. Pressing and limiting devices 19 are evenly fixedly mounted on both sides of the mounting frame 3. The pressing and limiting devices 19 include a floating claw block 26, a horizontal pressure plate 23, a first tension spring 22, a second tension spring 28, a second cylinder 27, a first pin 21, a second pin 24, a first cotter pin 20, a second cotter pin 25, and a first pin 25. The floating claw block 26 can float up and down within a certain range relative to the horizontal pressure plate 23. The upper working surface of the floating claw block 26 is arc-shaped, and the lower working surface is flat. Bearing the main locking force, the horizontal pressure plate 23 is rotatably connected to the front end of the second cylinder 27. The first tension spring 22 and the second tension spring 28 are distributed on both sides of the horizontal pressure plate 23. The floating claw block 26 is fixedly installed at both ends of the horizontal pressure plate 23 through the second pin 24 and the first pin 21. The second cylinder 27 uses the horizontal pressure plate 23 to press the floating claw block 26 onto the battery 2, thereby fixing and limiting the battery 2. The battery rack lock uses a floating claw type lock hook. The working surface of the floating claw block 26 adopts an arc structure design, which makes the locking and unlocking operations smooth in actual use without jamming, making it more convenient to use. The floating claw type lock hook of the battery rack, with the floating claw block 26 connected to the horizontal pressure plate through two pins, has strong tolerance in actual processing and manufacturing, thus reducing the difficulty of processing. The floating claw block 26 bears the main locking force, while the moving parts do not bear the locking force, which improves the service life of the parts. The structure is simple and reduces the manufacturing cost.

[0041] Working principle: The battery 2 in the mounting frame 3 can be removed and replaced through the bottom of the electrical device 1. During replacement, each cylinder 16 is activated simultaneously, causing the front end of each cylinder 16 to retract. At this time, the retracted cylinder 16 pulls the connecting drive arm 13 and the rotating adjusting column 12 through the connecting shaft 15, causing them to rotate. The rotating adjusting column 12, through the fixed chuck 18, drives each floating claw 8 to rotate synchronously. At this time, the upper end of the floating claw 8 and the horizontal pressure plate 9... The upper edge of the battery 2 will not be squeezed and fixed, so the battery 2 can be easily removed from the placement slot 5 for replacement. After the battery 2 is replaced, the cylinder 16 is activated again to extend the front end of the cylinder 16 forward and reset. At this time, by connecting the drive arm 13 and rotating the adjusting column 12, the floating claw 8 and the horizontal pressure plate 9 can be reset, so that the floating claw 8 and the horizontal pressure plate 9 press on both sides of the upper end of the battery 2, so that the battery 2 is firmly fixed in the placement slot 5. During the use of this device, the battery 2 can be replaced quickly and conveniently, and the battery 2 can be firmly fixed and pressed in the placement slot 5.

[0042] The second cylinder 27, using the horizontal pressure plate 23, allows the floating claw block 26 to press against the battery 2, thus fixing and limiting the battery 2. The battery rack uses a floating claw type locking hook, and the working surface of the floating claw block 26 adopts an arc-shaped structure design. In actual use, the locking and unlocking operations are smooth and there will be no jamming, making it more convenient to use. The floating claw type locking hook connects the floating claw block 26 to the horizontal pressure plate through two pins, which has strong tolerance in actual processing and manufacturing, thereby reducing the difficulty of processing. The floating claw block 26 bears the main locking force, while the moving parts do not bear the locking force, improving the service life of the parts. The structure is simple and reduces the manufacturing cost.
