Detailed implementation manners
[0035] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation to the protection scope of the present invention.
[0036] Please refer to Figure 1-10 , the present invention provides a technical solution: a storage device that is easy to install and its installation method, including an energy storage box 1, a concave block 7 is fixedly installed at the bottom of the energy storage box 1, a supporting slider 6 is slidably connected inside the concave block 7, a moving base 4 is fixedly installed at the top of the supporting slider 6, an energy storage battery 2 is arranged at the top of the moving base 4, a motor 17 is fixedly installed on one side of the energy storage box 1, a threaded rod 18 is fixedly installed at the output end of the motor 17, a moving block 19 is threadedly connected to the surface of the threaded rod 18, and the top of the moving block 19 is fixedly connected to the bottom of the moving base 4.
[0037] Start the motor 17, which in turn drives the threaded rod 18 to rotate, and then drives the moving block 19 to move, causing the moving base 4 to slide inside the energy storage box 1. At the same time, the support slider 6 will slide inside the concave block 7, and then move the energy storage battery 2 to the outside of the energy storage box 1. When installing the energy storage battery 2 into the energy storage box 1, place the energy storage battery 2 on the moving base 4, start the motor 17 in reverse, so that the motor 17 drives the threaded rod 18 to rotate in reverse, and then drives the moving block 19 to move towards the inside of the energy storage box 1. Then, the support slider 6 slides inside the concave block 7, and then moves the energy storage battery 2 to the inside of the energy storage box 1. This makes it convenient to move the energy storage battery 2 into the energy storage box 1, facilitates the installation of the energy storage battery 2, improves the convenience of installing the energy storage battery 2, and enables the staff to directly install the energy storage battery 2 from the outside, reducing the difficulty of installing the energy storage battery 2 into the energy storage box 1.
[0038] A connecting seat 24 is fixedly installed at the bottom of the moving base 4. A connecting rotating shaft 25 is rotatably connected inside the connecting seat 24. A support leg 27 is fixedly sleeved on the surface of the connecting rotating shaft 25. A second torsion spring 26 is movably sleeved on the surface of the connecting rotating shaft 25. Both ends of the second torsion spring 26 are fixedly connected to the connecting seat 24 and the support leg 27 respectively.
[0039] When the moving base 4 moves to the outside of the energy storage box 1, the support leg 27 will no longer be blocked by the inner wall of the energy storage box 1. Then, the support leg 27 is reset by the torsion of the second torsion spring 26, and the support leg 27 is vertically downward, thus realizing the support of the moving base 4. When the moving base 4 moves towards the inside of the energy storage box 1, due to the support leg 27 being blocked by the energy storage box 1, the support leg 27 rotates around the connecting rotating shaft 25 and blocks, and the support leg 27 drives the connecting rotating shaft 25 to block, causing the second torsion spring 26 to deform, and then the support leg 27 is retracted into the energy storage box 1, facilitating the support of the moving base 4, and preventing the moving base 4 from tilting, improving the load-bearing capacity of the moving base 4.
[0040] A sliding extrusion rod 20 is slidably connected inside the moving base 4. One end of the sliding extrusion rod 20 is rotatably connected to a sliding wheel 21. An inclined slideway 5 is provided on the inner wall of the energy storage box 1. The sliding wheel 21 is slidably connected inside the inclined slideway 5. The sliding extrusion rod 20 slides through the moving base 4 and extends to one side of the moving base 4. A clamping plate 3 is fixedly installed at one end of the sliding extrusion rod 20. A fixed sliding plate 23 is fixedly sleeved on the end of the sliding extrusion rod 20 located inside the moving base 4. The fixed sliding plate 23 is slidably connected inside the moving base 4. A spring 22 is movably sleeved on the sliding extrusion rod 20. One end of the spring 22 close to the fixed sliding plate 23 is fixedly connected to the fixed sliding plate 23, and the other end of the spring 22 away from the fixed sliding plate 23 is fixedly connected to the inner wall of the moving base 4.
[0041] When the moving base 4 moves outwards of the energy storage box 1, the sliding wheel 21 will slide inside the inclined slideway 5. Since the shape of the inclined slideway 5 consists of a horizontal shape and an inclined shape, the sliding wheel 21 will gradually slide towards the inclined surface, and then the sliding extrusion rod 20 will be reset by the elastic force of the spring 22, so that the clamping plate 3 no longer clamps the energy storage box 1. When the moving base 4 enters the inside of the energy storage box 1, the sliding wheel 21 will slide upwards along the inclined surface of the inclined slideway 5, and then the sliding extrusion rod 20 will slide into the inside of the moving base 4, and the fixed sliding plate 23 will squeeze the spring 22, so that the clamping plate 3 squeezes the energy storage battery 2, thereby realizing the fixation of the energy storage battery 2, facilitating the fixation of the energy storage battery 2, and improving the convenience of fixing the energy storage battery 2.
[0042] Four fixed guide rods 8 are fixedly installed on the top of the moving base 4. An extrusion plate 10 is slidably connected to the four fixed guide rods 8. A top plate 11 is fixedly installed on the four fixed guide rods 8. Elastic force springs 9 are movably sleeved on the four fixed guide rods 8. The upper ends of the four elastic force springs 9 are fixedly connected to the bottom of the top plate 11, and the lower ends of the four elastic force springs 9 are fixedly connected to the top of the extrusion plate 10. A rotating shaft 12 is rotatably connected to the inner wall of the energy storage box 1. A winding wheel 14 is fixedly sleeved on the rotating shaft 12. A first torsion spring 13 is movably sleeved on the rotating shaft 12. The two ends of the first torsion spring 13 are fixedly connected to the winding wheel 14 and the energy storage box 1 respectively. A winding rope 15 is wound on the winding wheel 14. One end of the winding rope 15 is fixedly connected to the extrusion plate 10. A transmission wheel 16 is arranged on the top of the top plate 11, and the winding rope 15 is in surface transmission connection with the transmission wheel 16.
[0043] When the moving base 4 moves outwards, the top plate 11 and the fixed guide rods 8 move following the top plate 11, and then one end of the winding rope 15 is pulled to move, and then the winding rope 15 drives the winding wheel 14 and the rotating shaft 12 to rotate, causing the first torsion spring 13 to deform. Then when the moving base 4 is about to completely move out of the energy storage box 1, all the winding rope 15 on the winding wheel 14 will be released, and then the winding rope 15 will no longer be pulled, and the winding rope 15 will pull the extrusion plate 10 to slide on the fixed guide rods 8, thereby squeezing the elastic force spring 9, so that the extrusion plate 10 no longer squeezes the energy storage battery 2. When the moving base 4 moves into the inside of the energy storage box 1, the extrusion plate 10 will move downwards, and the extrusion plate 10 will squeeze the energy storage battery 2, thereby fixing the energy storage battery 2 and preventing the energy storage battery 2 from moving up and down inside the energy storage box 1, improving the stability of the energy storage battery 2 inside the energy storage box 1.
[0044] The setting of the first torsion spring 13 and the winding wheel 14 can wind up the winding rope 15 to avoid winding and knotting inside.
[0045] An energy storage device convenient for installation and its installation method, including the following steps:
[0046] First step: Start the motor 17, so that the motor 17 drives the threaded rod 18 to rotate, and then drives the moving block 19 to move, so that the moving base 4 moves inside the energy storage box 1. At the same time, the support slider 6 slides inside the concave block 7, and then moves the energy storage battery 2 to the outside of the energy storage box 1. When installing the energy storage battery 2 into the energy storage box 1, place the energy storage battery 2 on the moving base 4, reverse-start the motor 17, so that the motor 17 drives the threaded rod 18 to rotate in the reverse direction, and then drives the moving block 19 to move towards the inside of the energy storage box 1, and then makes the support slider 6 slide inside the concave block 7, and then moves the energy storage battery 2 into the energy storage box 1, which is convenient for moving the energy storage battery 2 into the energy storage box 1 and facilitating the installation of the energy storage battery 2;
[0047] Second step: After the moving base 4 enters the energy storage box 1, the sliding wheel 21 slides upward along the inclined surface of the inclined slideway 5, and then the sliding extrusion rod 20 slides into the moving base 4, and the fixed slide plate 23 squeezes the spring 22, and then the clamping plate 3 squeezes the energy storage battery 2, so as to fix the energy storage battery 2;
[0048] Third step: When the moving base 4 moves towards the inside of the energy storage box 1, the extrusion plate 10 moves downward, and the extrusion plate 10 squeezes the energy storage battery 2, so as to fix the energy storage battery 2.
[0049] Working principle:
[0050] Start the motor 17, which in turn drives the threaded rod 18 to rotate, and then drives the moving block 19 to move, causing the moving base 4 to move inside the energy storage box 1. At the same time, the support slider 6 slides inside the concave block 7, and then moves the energy storage battery 2 to the outside of the energy storage box 1. When installing the energy storage battery 2 into the energy storage box 1, place the energy storage battery 2 on the moving base 4, reverse-start the motor 17, so that the motor 17 drives the threaded rod 18 to rotate in the reverse direction, and then drives the moving block 19 to move towards the inside of the energy storage box 1. Then, the support slider 6 slides inside the concave block 7, and then moves the energy storage battery 2 to the inside of the energy storage box 1, which is convenient for moving the energy storage battery 2 into the energy storage box 1 and facilitating the installation of the energy storage battery 2. When the moving base 4 moves to the outside of the energy storage box 1, the support leg 27 will no longer be blocked by the inner wall of the energy storage box 1. Then, the support leg 27 is reset by the torsion force of the second torsion spring 26, so that the support leg 27 is vertically downward, thus realizing the support for the moving base 4. When the moving base 4 moves towards the inside of the energy storage box 1, due to the support leg 27 being blocked by the energy storage box 1, the support leg 27 rotates around the connecting rotating shaft 25 and is blocked, so that the support leg 27 drives the connecting rotating shaft 25 to be blocked, and then the second torsion spring 26 deforms, and the support leg 27 is contracted into the inside of the energy storage box 1, which is convenient for supporting the moving base 4.
[0051] When the moving base 4 moves towards the outside of the energy storage box 1, the sliding wheel 21 slides inside the inclined slideway 5. Since the shape of the inclined slideway 5 consists of a horizontal shape and an inclined shape, the sliding wheel 21 will gradually slide towards the inclined surface, and then the sliding extrusion rod 20 is reset by the elastic force of the spring 22, so that the clamping plate 3 no longer clamps the energy storage box 1. After the moving base 4 enters the inside of the energy storage box 1, the sliding wheel 21 slides upward along the inclined surface of the inclined slideway 5, and then the sliding extrusion rod 20 slides towards the inside of the moving base 4, and the fixed slide plate 23 squeezes the spring 22, so that the clamping plate 3 squeezes the energy storage battery 2, thus realizing the fixation of the energy storage battery 2.
[0052] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
