[0007] The present invention further describes that the bottom of the placement groove is provided with a sliding groove, the adaptation component includes a trapezoidal block, a base, four sliding rods and four springs, the placement cavity includes a left cavity and a right cavity, the left cavity and the right cavity are separated from each other and located at the bottom of the placement groove, and the inner sides of the two are connected by a pin; the trapezoidal block is slidably connected in the sliding groove, and its upper surface is fixed to the bottom surface of the left cavity; through holes are provided on both the left and right sides of the placement groove, a slider is fixed at the bottom of the placement groove, a hole is provided in the middle of the slider, and a connecting rod is slidably connected in the hole; the right end of the connecting rod is fixed to the left side of the trapezoidal block.

[0008] The present invention further describes that the base is located below the battery cavity, the battery cavity is provided with sliding holes around its perimeter, and four sliding rods are slidably connected in the sliding holes. The bottom ends of the four sliding rods are fixed to the upper surface of the base, and four springs are respectively sleeved on the outside of the four sliding rods. The upper ends of the four sliding rods are provided with limiters. A top rod is fixed in the middle of the base, the upper end of the top rod is in contact with the lower surface of the trapezoidal block, and the upper end of the top rod is spherical.

[0009] The present invention further illustrates that the interior of the trapezoidal block is hollow, the interior of the connecting rod is provided with a threaded hole, and the threaded hole communicates with the interior of the trapezoidal block; a threaded shaft is threadedly connected to the threaded hole, and a top plate is connected to the right end of the threaded shaft by a bearing; the bottom of the trapezoidal block is provided with several small holes, and a round rod is slidably connected inside; each of the round rods is provided with a limit block at its upper end.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention installs an integrated battery compartment in the crane remote control. When the stored power in the lithium battery is depleted, the internal lithium battery is replaced, a spare battery is installed, and the removed battery is charged, thereby ensuring that the crane remote control can be used continuously. During the battery replacement process, the non-tightening quick disassembly and assembly are used to replace the battery. The movement of the push rod is based on the lever principle, which is more labor-saving and easier to operate, while generating a sufficiently large thrust. It can achieve IP68 protection in a limited space. The battery or other electrical connections are reliable, and the protection is reliable.

[0014] For lithium batteries of different lengths, it can adapt to the length of the lithium battery so that the battery can be smoothly inserted into the mounting cavity, ensuring the adaptability of the battery compartment and guaranteeing the application range. Moreover, the mounting cavity drives the battery to move, so that the right side of the lithium battery is separated from the right side of the inner wall of the mounting groove, reducing the friction between the lithium battery and the inner wall of the mounting groove when removing the lithium battery, thereby reducing wear and improving the battery's service life.

[0015] When lithium batteries expand after long-term use, they are relatively difficult to remove. When the push rod rubs against the bottom surface of the trapezoidal block, it contacts the boss, which generates a vibration. This vibration can loosen the expanded lithium battery from the mounting cavity, making it easier to remove the expanded lithium battery without damaging it, thus protecting the lithium battery.

[0028] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-10 The present invention provides a technical solution: a quick-disassembly protective integrated battery compartment, including a battery cavity 1. Positioning blocks 2 are fixedly installed on both the front and rear sides of the battery cavity 1 by bolts. A push rod 3 is connected to the inner side of the front positioning block 2 by a pin shaft. A snap-fit ​​block 4 is connected to the rear side of the push rod 3 by a pin shaft. A snap-fit ​​rod 5 is fixed to the inner wall of the rear positioning block 2. The snap-fit ​​block 4 and the snap-fit ​​rod 5 are snap-fitted and fixed to each other.

[0030] A mounting groove 6 is provided in the middle of the battery cavity 1. A lithium battery 7 is placed inside the mounting groove 6. Three countersunk holes are provided on the left side of the mounting groove 6, and each countersunk hole is slidably connected to an electric shaft 8. The electric shaft 8 is electrically connected to the output end of the lithium battery 7. A groove is provided on the outer side of the left end of each of the three electric shafts 8, and a connecting sleeve 81 is fitted inside the groove. The three connecting sleeves 81 are fixedly connected to each other. A mounting cavity is provided at the bottom of the inner wall of the mounting groove 6, and an adaptation component is provided at the bottom of the mounting cavity.

[0031] The integrated battery compartment is installed in the gantry crane remote control. When the stored power in the lithium battery 7 is depleted, the internal lithium battery 7 is replaced, a spare battery is installed, and the removed battery is charged to ensure the continuous use of the gantry crane remote control. During the battery replacement process, the latch block 4 is opened to disengage it from the latch rod 5. Then, the push rod 3 is opened, and the depleted lithium battery 7 is removed. The fully charged lithium battery 7 is then placed into the mounting slot 6 and embedded in the mounting cavity. The output end of the lithium battery 7 is connected to the power shaft 8 for conduction, so as to power the gantry crane remote control. The battery is replaced by a non-tightening quick disassembly and assembly. The movement of the push rod 3 is based on the lever principle, which is more labor-saving and easier to operate. At the same time, it generates a large enough thrust to achieve IP68 protection in a limited space. The battery or other electrical connections are reliable, and the protection is reliable.

[0032] A screw 82 is fixed to the left end of the energized shaft 8. A conductive cavity 83 is fixed to the left side of the inner wall of the battery cavity 1. A hydraulic plate 831 is slidably connected to the inner wall of the conductive cavity 83. A threaded sleeve 832 is fixed to the right side of the hydraulic plate 831, and an electrolyte solution is filled on the left side. The threaded sleeve 832 is threadedly connected to the screw 82. The conductive cavity 83 is electrically connected to the external drive component.

[0033] After the lithium battery 7 is placed in the mounting slot 6, its left output end is in contact with the energized shaft 8. The energized shaft 8 is subjected to force and slides to the left through the countersunk hole, driving the screw 82 to move to the left. It also drives the hydraulic plate 831 to slide to the left along the inner wall of the conductive cavity 83 through the threaded sleeve 832. The electrolyte solution is squeezed and generates a reaction force, which in turn holds the lithium battery 7 in place through the energized shaft 8, increasing the clamping force on the battery, improving the stability of the battery after placement, and preventing it from falling off. This battery compartment can be used for lithium batteries 7 of different models and lengths, with a wide range of applications and strong adaptability. The electrolyte solution conducts electricity to ensure that the external drive components are powered smoothly to drive the operation of the crane remote control.

[0034] The bottom of the mounting groove 6 is provided with a sliding groove. The fitting components include a trapezoidal block 61, a base 62, four sliding rods 63 and four springs 64. The mounting cavity includes a left cavity 65 and a right cavity 66. The left cavity 65 and the right cavity 66 are separated from each other and located at the bottom of the mounting groove 6. The inner sides of the two are connected by a pin.

[0035] The trapezoidal block 61 is slidably connected in the groove, and its upper surface is fixed to the bottom surface of the left cavity 65. The left and right sides of the mounting groove 6 are provided with through holes. The bottom of the mounting groove 6 is fixed with a slider 67. The middle of the slider 67 is provided with a hole, and a connecting rod 68 is slidably connected in the hole. The right end of the connecting rod 68 is fixed to the left side of the trapezoidal block 61.

[0036] The base 62 is located below the battery cavity 1. Sliding holes are provided around the battery cavity 1, and four sliding rods 63 are slidably connected in the sliding holes. The bottom ends of the four sliding rods 63 are fixed to the upper surface of the base 62. Four springs 64 are respectively sleeved on the outside of the four sliding rods 63. Limiting devices are provided at the upper ends of the four sliding rods 63. A top rod 69 is fixed in the middle of the base 62. The upper end of the top rod 69 is in contact with the lower surface of the trapezoidal block 61, and the upper end of the top rod 69 is spherical.

[0037] For lithium batteries 7 of different lengths, while the power shaft 8 adapts to the lithium battery 7, the operator can press the battery cavity 1 to apply force. The slide rod 63 slides through the sliding hole, the spring 64 deforms under force, and at the same time the push rod 69 moves relative to the battery cavity 1. The push rod 69 pushes against the trapezoidal block 61, causing it to move to the left. The trapezoidal block 61 drives the connecting rod 68 to slide in the hole of the slider 67, and at the same time drives the left cavity 65 to move to the left, so that the placement cavity moves to the left to adapt to the length of the lithium battery 7, so that the battery can be smoothly inserted into the placement cavity, ensuring the adaptability of the battery compartment and guaranteeing the application range.

[0038] When removing the lithium battery 7, press the battery cavity 1. The push rod 69 pushes against the trapezoidal block 61 and moves to the left, thereby moving the placement cavity to the left. The placement cavity moves the lithium battery 7 to the left, and the lithium battery 7 squeezes the energized shaft 8. The push rod 69 continues to squeeze until the trapezoidal block 61 reaches the left side of the push rod 69. Then, continue pressing the battery cavity 1. The push rod 69 pushes against the bottom of the right cavity 66, causing the right cavity 66 to rotate through the shaft and lift up, thereby lifting the right side of the lithium battery 7. At the same time, as the placement cavity moves to the left, the right end of the right cavity 66 disengages from the through hole on the right side of the placement groove 6, so that the lithium battery 7 can be easily removed. The movement of the battery by the placement cavity also causes the right side of the lithium battery 7 to disengage from the right side of the inner wall of the placement groove 6, reducing friction between the lithium battery 7 and the inner wall of the placement groove 6 when removing the lithium battery 7, thereby reducing wear and improving the battery's service life.

[0039] The interior of the trapezoidal block 61 is hollow, and the interior of the connecting rod 68 is provided with a threaded hole, which is connected to the interior of the trapezoidal block 61.

[0040] A threaded shaft 681 is connected to the threaded hole by an internal thread. The right end of the threaded shaft 681 is connected to a top plate 682 by a bearing. Several small holes are provided at the bottom of the trapezoidal block 61, and a round rod 611 is slidably connected inside. Limiting blocks are provided at the upper end of the round rod 611.

[0041] The lower end of the round rod 611 is flush with the bottom surface of the trapezoidal block 61, the upper end of the round rod 611 is in contact with the top plate 682, and the left end of the threaded shaft 681 is fixed with a gear plate 683.

[0042] When the lithium battery 7 is removed, if the lithium battery 7 does not expand, the bottom end of the round rod 611 is flush with the bottom surface of the trapezoidal block 61. The bottom surface of the trapezoidal block 61 is a smooth plane, making it easy to remove the lithium battery 7 with low wear and relatively increased service life of the structure.

[0043] When the lithium battery 7 expands after long-term use, it becomes relatively difficult to remove. The operator can rotate the toothed disc 683 to drive the threaded shaft 681 to rotate. The threaded shaft 681 moves to the right while rotating through the threaded hole, thereby moving the top plate 682 to the right until the top plate 682 contacts the upper end of the round rod 611, thus pushing the round rod 611 out of the small hole. At this time, a boss is formed on the bottom surface of the trapezoidal block 61. When the bottom surface of the trapezoidal block 61 rubs against the upper end of the top rod 69, the upper end of the top rod 69 repeatedly contacts and separates from the boss, thus generating a vibration. This vibration can shake the expanded lithium battery 7, loosening it from the mounting cavity, so as to remove the expanded lithium battery 7 without damaging it, thus protecting the lithium battery 7.

[0044] A gear 821 is fixed to the outside of the screw 82, and the gear 821 meshes with the gear disk 683.

[0045] The thickness of the gear disk 683 is greater than the thickness of the gear 821;

[0046] When the gear 683 rotates, it drives the gear 821 to rotate through meshing. The gear 821 drives the screw 82 to rotate, causing it to rotate and move to the right inside the threaded sleeve 832. The threaded sleeve 832 drives the hydraulic plate 831 to move relative to it, thereby reducing the force of the electrolyte solution on the hydraulic plate 831 and reducing the squeezing force on the lithium battery 7. After the lithium battery 7 expands, the squeezing force on it is reduced when it is removed, so that the battery can be removed more quickly. The wear on the lithium battery 7 is further reduced, which significantly improves the battery's service life. Since the thickness of the gear 683 is greater than that of the gear 821, they will not disengage when they mesh and rotate, and the structure can operate smoothly.
