[0024] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0025] Example 1: This utility model provides an automatic lifting and lifting device, which includes a frame 1, a steering mechanism 2, wheels 3, and a braking mechanism 4. The frame 1 is rectangular, the wheels 3 are located at the bottom of the frame 1 and are driven by a motor, the bottom of the frame 1 is provided with a lifting mechanism, the lifting mechanism is located at both ends of the frame 1, the steering mechanism 2 is located at the top of the frame 1, and the braking mechanism 4 includes a handbrake 41 and a foot brake 42. The foot brake 42 is located on one side of the steering mechanism 2, and the handbrake 41 is located on the frame 1.
[0026] The frame 1 includes a crossbeam 11, a main beam 12, and a secondary beam 13. The main beam 12 and the secondary beam 13 are located on both sides of the crossbeam 11. The main beam 12 is located on the side of the crossbeam 11 away from the steering mechanism 2 and is fixedly connected to the crossbeam 11 at both ends. The secondary beam 13 is located on the side of the crossbeam 11 closer to the steering mechanism 2 and is fixedly connected to the crossbeam 11 at both ends. The crossbeam 11, the main beam 12, and the secondary beam 13 are all hollow structures. The crossbeam 11 has a first square tube 111 that is slidably connected on both sides. The main beam 12 at both ends has a second square tube 121 that is slidably connected on the side away from the crossbeam 11. The secondary beam 13 at both ends has a third square tube 131 that is slidably connected on the side away from the crossbeam 11. The secondary beam 13 is connected to the crossbeam 11 by a reinforcing rib 14.
[0027] Multiple fourth square tubes 122 are provided between the two main beams 12, and the two sides of the fourth square tubes 122 are fixedly connected to the two main beams 12. Multiple fifth square tubes 132 are provided between the two secondary beams 13, and the two sides of the fifth square tubes 132 are fixedly connected to the secondary beams 13.
[0028] During use, the lifting mechanism supports both ends of the body-in-white, allowing the sides of the body-in-white to be secured to the frame 1. By adjusting the height of the lifting mechanism, vehicles of different heights can be secured to the frame 1. Depending on the vehicle model, the crossbeam 11, main beam 12, and sub-beam 13 are extended through the first square tube 111, the second square tube 121, and the third square tube 131, respectively. By traction of the frame 1 or rotation of the drive shaft of the wheel 3 driven by the motor, the position of the body-in-white is adjusted under the action of the wheel 3, realizing the transfer of the body-in-white. At the same time, it cooperates with the steering mechanism 2 to adjust the direction during the transfer. After the transfer is completed or the position is adjusted, the frame 1 is braked by the handbrake 41 or the foot brake 42 to solve the problems of existing technology where movement is controlled by the limit column and the ground, requiring two operations to lock the position, and the lack of hand operation space.
[0029] Compared with existing technologies, the lifting mechanism at the bottom of the frame 1 can automatically raise and lower to support body-in-white of different heights. This allows the device to adapt to various vehicle models, improving versatility and flexibility. The crossbeam 11 has a slidingly connected first square tube 111 on both sides, the main beam 12 has a second square tube 121 on the side away from the crossbeam 11, and the sub-beam 13 has a third square tube 131 on the side away from the crossbeam 11. This allows the frame 1 to be expanded according to the size of the vehicle model, enhancing the adaptability of the device. The expandable frame structure can more flexibly adapt to body-in-white of different sizes. The steering mechanism 2 is located on the top of the frame 1. Together with the motor-driven wheels 3, it achieves precise adjustment of the body-in-white position. The motor drives the drive shaft of the wheels 3 to rotate. Combined with the steering mechanism 2, directional adjustment during transportation can be easily achieved. Moreover, compared with the method of controlling movement through the limit column and the ground, which requires two operations to lock the position, the handbrake 41 and foot brake 42 provide dual braking protection, which is more direct and reliable, and provides ample hand operating space.
[0030] Example 2: In the above examples, the process of expanding the frame 1 through the first square tube 111, the second square tube 121, and the third square tube 131 can easily lead to instability in the position of the body-in-white during the support process. Therefore, this application example optimizes the frame 1 based on the above examples.
[0031] In this embodiment, positioning components 5 are provided on the crossbeam 11, main beam 12, and secondary beam 13. The crossbeam 11, main beam 12, and secondary beam 13 limit and fix the first square tube 111, the second square tube 121, and the third third tube 131 respectively through the positioning components 5. The first square tube 111, the second square tube 121, and the third third tube 131 are all provided with a first sliding groove 15. The first square tube 111, the second square tube 121, and the third third tube 131 are slidably connected to the crossbeam 11, the main beam 12, and the secondary beam 13 respectively through the first sliding groove 15.
[0032] The positioning component 5 includes a first positioning frame 51 and a screw 52. The first positioning frame 51 is fixedly connected to the crossbeam 11, the main beam 12, and the secondary beam 13 respectively. The screw 52 passes through the first positioning frame 51 and is connected to the first positioning frame 51 by a thread. The screw 52 is provided with a positioning plate that is slidably connected to the first slide groove 15.
[0033] The crossbeam 11, main beam 12, and secondary beam 13 are all equipped with slidingly connected positioning blocks 6. The positioning block 6 includes a second positioning frame 61. The bottom of the second positioning frame 61 is provided with a first opening 62. Threaded holes and bolts 64 corresponding to the threaded holes are provided on both sides of the first opening 62 at the bottom of the second positioning frame 61. The top of the second positioning frame 61 is provided with a second opening 63, which is trapezoidal.
[0034] In use, the frame 1 is expanded by moving the first square tube 111, the second square tube 121, and the third square tube 131 within the crossbeam 11, the main beam 12, and the sub-beam 13, respectively. The first sliding grooves 15 on the first square tube 111, the second square tube 121, and the third square tube 131 slide along their corresponding positioning plates. After expanding to the appropriate position, rotating the screw 52 causes the positioning plate to contact the inner wall of the first sliding groove 15, thus limiting the corresponding first square tube 111, second square tube 121, and third square tube 131, thereby controlling the movement of the first square tube 111. 11. The positions of the second square tube 121 and the third third tube 131 are precisely adjusted and fixed to ensure the stability of the frame 1. During the process of using the frame 1 to support the body-in-white, the corresponding positioning block 6 is slid. The positioning block 6 slides on the corresponding crossbeam 11, main beam 12, sub-beam 13, and the first square tube 111, second square tube 121, and third third tube 131. When it slides to the corresponding position, the second positioning frame 61 is clamped and fixed through the first opening 62 at the bottom. The bottom of the body-in-white is limited and fixed by the second opening 63 on the corresponding second positioning frame 61.
[0035] Compared with existing technologies, the positioning component 5 limits and fixes the first square tube 111, the second square tube 121, and the third square tube 131. A screw 52 passes through the first positioning frame 51 and is connected to a positioning plate, which is slidably connected to the first groove 15 on the square tube. After being extended to the appropriate position, the screw 52 is rotated to make the positioning plate tightly contact the inner wall of the first groove 15, achieving precise adjustment and fixation of the square tube, thereby ensuring the stability of the frame 1. The positioning block 6 is slid to the corresponding position, and the second positioning frame 61 is clamped and fixed through the first opening 62 at the bottom and the bolt 64, ensuring the stability of the body-in-white during the support process.
[0036] Example 3: In the above examples, when the body-in-white is positioned or fixed, it may rely on only a single fixing point, which may easily lead to unstable fixing and displacement during processing or transportation. Therefore, this application example optimizes the second positioning frame 61 based on the above examples.
[0037] In this embodiment, the second opening 63 is provided with hinged first limiting plates 65 on both sides. The top of the first limiting plate 65 is hinged to the inner wall of the second opening 63. The bottom of the first limiting plate 65 is connected to the second opening 63 by a first spring 67. The first limiting plate 65 has a concave portion in the middle. The first limiting plate 65 has a second limiting plate 66 on one side. The bottom of the second limiting plate 66 is hinged to the first limiting plate 65. The top of the first limiting plate 65 is located at the corresponding position of the concave portion and is connected to the concave portion by a second spring 68.
[0038] During use, when the body-in-white is inserted into the second opening 63 on the second positioning frame 61, the bottom of the body-in-white presses against the first limiting plate 65. Under the action of the first spring 67, the first limiting plate 65 contacts the bottom of the body-in-white, limiting and fixing it. Simultaneously, the second limiting plate 66, compressed by the second spring 68, rotates around the hinge point between its bottom and the first limiting plate 65, causing the second limiting plate 66 to contact both sides of the bottom of the body-in-white, further limiting and fixing it. Both the first limiting plate 65 and the second limiting plate 66 are connected by springs, possessing a certain degree of elasticity to adapt to body-in-whites of different sizes and shapes. When the size of the body-in-white changes slightly, the spring's elasticity ensures that the limiting plates always maintain close contact with the body-in-white. The concave portion on the first limiting plate 65 effectively prevents the top of the second limiting plate 66 from contacting the body-in-white during the process of being limited and fixed by the second limiting plate 66.
[0039] Compared to existing technologies, the second positioning frame 61 has hinged first limiting plates 65 on both sides of the second opening 63. The bottom of the first limiting plates 65 is connected to the second opening 63 via a first spring 67. When the car body is stuck in the second opening 63, its bottom presses against the first limiting plate 65, and the first limiting plate 65, under the action of the first spring 67, makes tight contact with the bottom of the car body, thus initially limiting and fixing the car body. Furthermore, a second limiting plate 66 is provided on one side of the first limiting plate 65. The bottom of the second limiting plate 66 is hinged to the first limiting plate 65 and connected to the concave portion at the top of the first limiting plate 65 via a second spring 68. Under the pressure of the second spring 68, the second limiting plate 66 flips to contact both sides of the bottom of the car body, further limiting and fixing the car body. This multi-point fixing method significantly enhances the stability of the fixation.
[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
