Description

Technical Field

[0001] This utility model belongs to the field of vehicle outriggers, and more specifically, relates to an outrigger for motorhomes. Background Technology

[0002] RVs are a type of fashionable vehicle imported from abroad. The home furnishings on the vehicle include: bedding, stove, refrigerator, cabinets, sofa, dining table and chairs, washing facilities, air conditioning, television, audio equipment and other furniture and appliances. They can be divided into driving area, living area, bedroom area, bathroom area, kitchen area, etc. RVs are a fashionable product that integrates "clothing, food, housing and travel", realizing "living while traveling and traveling while living".

[0003] Currently, the outriggers used in vehicles on the market are hydraulic outriggers. Their function is to raise the vehicle by lifting it up, thereby raising the vehicle to complete subsequent maintenance or other work.

[0004] Unlike regular vehicles, small motorhomes serve a different purpose: outdoor rest. Therefore, ensuring vehicle stability and minimizing shaking to guarantee sleep quality outdoors (especially in inclement weather) is a crucial issue. Simply transferring traditional hydraulic outriggers to a motorhome not only increases its load capacity but also makes the addition of hydraulic outriggers, which are similar in size to a regular 7-seater van, seem out of place. Furthermore, even when the outriggers are retracted, they increase the distance between the vehicle and the ground, increasing the risk of collisions while driving. Utility Model Content

[0005] To address the above deficiencies, this utility model provides a motorhome outrigger, comprising a fixed plate connected to the vehicle chassis, a crossbeam fixed to the bottom of the fixed plate for load-bearing, and a drive mechanism for driving the outrigger. The drive mechanism is installed at the left end of the crossbeam and includes a drive motor and a gearbox. The gearbox is welded to the crossbeam and has a communication port. A lead screw is installed inside the gearbox, and a matching nut is threaded onto the outer surface of the lead screw. The bottom end of the nut is hinged to the outrigger via a pin, and a through groove is provided at the bottom end of the crossbeam for the outrigger to move left and right.

[0006] The front and rear sides of the left end of the crossbeam are hinged with connecting rods by connecting pins. The two connecting rods located on the front and rear sides are respectively hinged to the front and rear sides of the support leg by connecting pins. The bottom end of the support leg is hinged with a ground plate by connecting pins.

[0007] Furthermore, a Hall switch for calculating the number of rotations of the lead screw is installed at the gearbox, and the drive motor is a forward and reverse motor, whose working cycle is when the lead screw nut moves from the left end to the right end.

[0008] Furthermore, the right end of the crossbeam is provided with a waist-shaped hole I for connecting with the connecting plate.

[0009] Furthermore, symmetrical waist-shaped holes II are also provided on the front and rear sides of the right end of the crossbeam.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] Unlike traditional vehicle outriggers, this outrigger abandons the structure of hydraulic outriggers. When installed on a small RV, it can be retracted to the bottom of the vehicle when not in use, without affecting normal vehicle driving. When in use, it can extend outwards to contact the ground and form a stable triangle with the connecting rod. The four outriggers installed at the bottom of the vehicle, together with the car tires, create a more stable state. Even in windy weather, it can reduce vehicle swaying and ensure that the user is in a comfortable sleeping environment. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example

[0020] like Figures 1 to 5As shown, this embodiment provides a motorhome outrigger, including a fixed plate 3 connected to the vehicle chassis, a crossbeam 1 fixed to the bottom of the fixed plate 3 for load-bearing, and a drive mechanism for driving the outrigger 10. The drive mechanism is installed at the left end of the crossbeam 1 and includes a drive motor 4 and a gearbox 5. It should be noted that the gearbox 5 is equipped with a bearing for fixing the position of the lead screw 7, and the output end of the drive motor 4 is fixed with a small gear (and equipped with a reducer). The end of the lead screw 7 is fixed with a large gear 6, and the small gear and the large gear 6 mesh and transmit power (both are bevel gears, realizing the work of the drive motor 4 driving the lead screw 7 to rotate). The gearbox 5 is welded to the crossbeam 1 and has a communication port. The lead screw 7 is installed inside the gearbox 5, and the outer surface of the lead screw 7 is threaded with a matching nut 8. The bottom end of the nut 8 is hinged to the outrigger 10 through a pin 9. In order to ensure the stability of the lead screw 7, two bearings are also installed in the crossbeam 1 and sleeved at both ends of the lead screw 7 (where there are threads, there may be...). Figure 5 As can be seen from the image (which will not be elaborated here), the bottom end of the crossbeam 1 has a through groove for the support leg 10 to move left and right. A Hall switch for calculating the number of rotations of the lead screw 7 is installed at the gearbox 5. It should be noted that the drive motor 4 is a forward and reverse motor. Its working cycle is determined by the number of rotations of the lead screw 8 from the left end to the right end of the lead screw 7, which can be determined by the number of rotations calculated by the Hall switch. This will not be elaborated here.

[0021] The front and rear sides of the left end of the crossbeam 1 are hinged with connecting rods 12 via connecting pins. The two connecting rods 12 on the front and rear sides are respectively hinged to the front and rear sides of the support leg 10 via connecting pins. The bottom end of the support leg 10 is hinged with a base plate 11 via a connecting pin, thus enabling the deployment and retraction of the support leg 10. Figure 3 and Figure 4 As shown.

[0022] Additionally, the right end of the crossbeam 1 is provided with a waist-shaped hole I for connecting with the connecting plate 2, and the front and rear sides of the right end of the crossbeam 1 are also provided with symmetrical waist-shaped holes II. The purpose of these holes is to make the RV legs on both sides more stable when connected through the connecting plate 2.

[0023] The RV support legs described in this embodiment require four legs for use, positioned between the four wheels of the RV. The left and right support legs, aligned in a straight line, are connected by a connecting plate 2 and reinforced to the bottom of the RV (e.g., ...). Figure 2 As shown), the other two RV outriggers are similar. It should be noted that the four drive motors 4 should work synchronously.

[0024] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
