DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , a motorized lifting frame for a motorhome, comprising a vertical steel bar 1 and horizontal steel bars 2 fixed to the upper and lower ends of the vertical steel bar 1. A fixed frame 3 is slidably arranged up and down between the vertical steel bars 1. A lifting member is arranged between the lower end of the upper horizontal steel bar 2 and the fixed frame 3, and the other end of the lifting member is fixedly connected to the fixed frame 3. A support frame 12 is fixedly connected to the outer end of the fixed frame 3. An adjustable connecting member is arranged at one end of the lower horizontal steel bar 2 away from the support frame 12.
[0022] Specific working principle and implementation method: Both the vertical steel bar 1 and the horizontal steel bars 2 are made of C-shaped steel. A rectangular frame is formed by the vertical steel bar 1 and the horizontal steel bars 2. The connection ends between the vertical steel bar 1 and the horizontal steel bars 2 are welded. A lifting member is arranged between the horizontal steel bar 2 and the fixed frame 3. The fixed frame 3 is driven to move up and down in the vertical steel bar 1 by the lifting member. The support frame 12 is driven to move up and down by the fixed frame 3. An adjustable connecting member is arranged at the lower end of the fixed frame 3. The connecting member is connected to the bumper at the rear end of the vehicle. The adjustable setting can adapt to different vehicle models. The advantage of such a design is that the support frame 12 and the fixed frame 3 are lifted up and down by the lifting member after being installed and connected to the bumper of the vehicle through the adjustable connecting member. When lifting up and down, goods can be carried, which is convenient for the loading and unloading and transportation of goods.
[0023] Such as Figure 2 and Figure 3As shown in the figure, the lifting member includes a first guide wheel 4 fixed to the lower end surface of the upper cross bar 2. Symmetric second guide wheels 5 are fixedly connected to the lower end of the fixed frame 3. A third guide wheel 7 is fixedly connected to the lower end of the cross bar 2 on one side of the first guide wheel 4. A regulator 6 is fixedly connected to the lower end of the cross bar 2 on the other side of the first guide wheel 4. A steel wire 9 is fixedly connected to the end of the regulator 6. The steel wire 9 is arranged passing through the first guide wheel 4, the second guide wheel 5 and the third guide wheel 7. A secondary beam 11 is fixedly connected to the outer end of the fixed frame 3. A winch 8 is rotatably connected between the secondary beams 11. A drive motor 10 is fixedly connected to the inner end of the secondary beam 11. The output end of the drive motor 10 is fixedly connected to the winch 8. The end of the steel wire 9 is fixed on the winch 8. The regulator 6 can tighten and adjust the end of the steel wire 9. The secondary beam 11 is used for connection and fixation. The winch 8 is rotatably connected between the secondary beams 11. The steel wire 9 is wound and guided through the upper and lower positions of the first guide wheel 4, the second guide wheel 5 and the third guide wheel 7. The drive motor 10 drives the winch 8 to rotate so that the steel wire 9 is wound around the winch 8. The rotation of the winch 8 drives the steel wire 9 to contract and release for adjustment. The operation is convenient and fast. And the operation of the drive motor 10 is facilitated by the first guide wheel 4, the second guide wheel 5 and the third guide wheel 7.
[0024] As Figure 1 shown in the figure, connecting plates 13 are symmetrically and fixedly connected inside the support frame 12. A support plate 14 is fixedly connected to the upper end of the connecting plate 13. Support frames 15 are fixedly connected to both ends of the support plate 14. The support plate 14 is fixed on the connecting plate 13. Support frames 15 are fixed at both ends of the support plate 14. A motorcycle can be stored between the two support frames 15, so that the motorcycle can be carried out.
[0025] As Figure 1 shown in the figure, a fixing rod 20 is fixedly connected to one end of the support frame 12 close to the vertical bar 1. A spare tire rack 21 is fixedly connected to the fixing rod 20. The fixing rod 20 is fixed on the upper end surface of the support frame 12 and is arranged at one of the vertical bars 1. The spare tire rack 21 is fixed on the fixing rod 20. A spare tire can be stored through the spare tire rack 21. There is a distance of the support frame 12 between the spare tire rack 21 and the support plate 14, so that they do not interfere with each other.
[0026] As Figure 4 shown in the figure, the connecting member includes a connecting rod 18. The connecting rod 18 is L-shaped. A connecting hole 19 is opened at the end of the connecting rod 18. A through perforation 17 is opened in the lower cross bar 2. The connecting rod 18 and the cross bar 2 are fixedly connected by bolts. The connecting rod 18 slides on the lower cross bar 2 and is adjusted according to the distance between the vehicle bumpers. After adjustment, the connecting rod 18 and the cross bar 2 are fixedly connected by bolts, which increases the overall practicality.
[0027] As Figure 2As shown in the figure, both sides of the upper end of the support frame 12 are fixedly connected with connecting frames 16. A plurality of mounting holes are provided in the connecting frames 16. The provision of the mounting holes in the connecting frames 16 can fix the toolbox on the connecting frames 16. The connecting frames 16 are symmetrically fixed at both ends of the support frame 12, which can increase the storage space.
[0028] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention.
