Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, and more specifically to an automatic leveling outrigger for a recreational vehicle. Background Art

[0002] RV is a vehicle that combines chassis and housing functions, also known as camper or mobile home. It is usually a small car or truck chassis with a residential house, including bedrooms, bathrooms, kitchens and living rooms. RV can provide travelers with independent accommodation and living space, and also allow people to get closer to nature and enjoy outdoor life.

[0003] After parking, the RV is supported on the ground by tires, which is prone to shaking. Therefore, many RVs now install outriggers at the bottom of the car. However, when the outriggers need to support the ground, the operator needs to squat and manually adjust the lowering of each leg and its lowering height to meet the RV's stable parking needs. The entire adjustment operation process is complicated; and adaptive leveling adjustments cannot be made for bumpy ground, which causes the supported RV to tilt, affecting the user experience. Utility Model Content

The starting motor drives the driving gear to rotate, and the threaded rod is driven to rotate through the meshing action with the driven gear. Under the thread thrust of the threaded rod, the threaded block drives the telescopic leg to move downward along the inner side of the fixed leg, so that the support block is supported on the ground, thereby completing the automatic support of the leg without manual operation.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The automatic leveling RV legs involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0020] Reference Figure 1-Figure 4 The utility model provides an automatic leveling RV outrigger, comprising an installation beam 1, fixed legs 2 are fixedly connected on both sides of the bottom of the installation beam 1, a telescopic leg 201 is installed at the bottom of the inner side of the fixed leg 2, a support block 202 is fixedly connected to the bottom of the telescopic leg 201, a square block 203 is fixedly connected to the inner side of the fixed leg 2, a threaded rod 204 is movably sleeved on the top of the square block 203, a threaded block 205 is fixedly connected to the inner side of the telescopic leg 201, the threaded block 205 is threadedly sleeved with the threaded rod 204, a fixing component 3 is installed in the middle of the bottom of the installation beam 1, and a leveling component 4 is installed on the inner side of the fixing component 3.

[0021] In the embodiment of the present application, when the outrigger needs to be supported on the ground, the starting motor 207 drives the driving gear 208 to rotate, and through the meshing action with the driven gear 206, drives the threaded rod 204 to rotate. Under the thread thrust of the threaded rod 204, the threaded block 205 drives the telescopic leg 201 to move downward along the inner side of the fixed leg 2, so that the support block 202 is supported on the ground, thereby completing the automatic support of the outrigger without manual operation. Starting the LED light 406 can illuminate the inside of the protective frame 401, and the position collector 405 can identify the bubble position inside the liquid bubble indicator 403. The position of the bubble is determined by an algorithm. The position collector 405 is a prior art and will not be described in detail. When the bubble inside the liquid bubble indicator 403 is located between the two marking lines 404, it indicates that the heights of both ends of the mounting beam 1 are the same and the RV remains horizontal. When the bubble is not between the two marking lines 404, the position collector 405 transmits a signal to the motor 207 of the leg in the direction of the bubble offset through the control system, so that the motor 207 continues to drive the telescopic leg 201 to extend downward, thereby increasing the height of the leg on this side, until the bubble is located between the two marking lines 404, thereby completing the automatic leveling of the leg.

[0022] In a preferred embodiment, a driven gear 206 is fixedly sleeved on the top of the outer side of the threaded rod 204, a motor 207 is fixedly connected to the top of the side of the fixed leg 2, and a driving gear 208 is fixedly connected to the output shaft of the motor 207. The driving gear 208 and the driven gear 206 are meshed with each other, and the diameter of the driving gear 208 is smaller than the diameter of the driven gear 206. When the motor 207 drives the driving gear 208 to rotate forward, the telescopic leg 201 extends from the inner side of the fixed leg 2. When the motor 207 drives the driving gear 208 to rotate reversely, the telescopic leg 201 retracts into the inner side of the fixed leg 2.

[0023] In a preferred embodiment, the fixing assembly 3 includes a first fixing block 301, the top of the first fixing block 301 is fixedly connected to the bottom of the mounting beam 1, the side of the first fixing block 301 is movably sleeved with a latch rod 302, the end of the latch rod 302 away from the leveling assembly 4 is fixedly connected with a handle rod 303, the outer side of the latch rod 302 is fixedly sleeved with a connecting block 304, the outer side of the latch rod 302 is movably sleeved with a spring 305, and the spring 305 is located between the first fixing block 301 and the connecting block 304. A fixing groove 411 is provided on both sides of the protection frame 401, and the fixing groove 411 is adapted to the latch rod 302. The spring 305 generates a thrust on the connecting block 304, so that the latch rod 302 is inserted into the inner side of the fixing groove 411, thereby completing the fixation of the protection frame 401. The protection frame 401 protects the LED lamp 406, the position collector 405 and the liquid bubble indicator 403 from external pollution, thereby preventing the position collector 405 from identifying the liquid bubble indicator 403.

[0024] In a preferred embodiment, the leveling component 4 includes a protective frame 401, a position collector 405 and a second fixed block 402. A liquid bubble indicator 403 is fixedly connected to the inner side of the second fixed block 402. A marking line 404 is provided on the outer side of the liquid bubble indicator 403. The LED light 406 serves as lighting, so that the position collector 405 can easily collect and identify the image of the liquid bubble indicator 403.

[0025] In a preferred embodiment, the LED lamp 406, the position collector 405 and the top of the second fixed block 402 are all fixedly connected to the bottom of the mounting beam 1, and the position collector 405 is electrically connected to the motor 207 through the control system. The position collector 405 uses computer vision technology and image processing algorithms to extract the position of the bubbles inside the liquid bubble indicator 403. When the bubble position is offset, the corresponding motor 207 is controlled to adjust the operation.

[0026] The working principle of the utility model is as follows: when the outrigger needs to be supported on the ground, the starting motor 207 drives the driving gear 208 to rotate, and through the meshing action with the driven gear 206, the threaded rod 204 is driven to rotate. Under the thread thrust of the threaded rod 204, the threaded block 205 drives the telescopic leg 201 to move downward along the inner side of the fixed leg 2, so that the support block 202 is supported on the ground, thereby completing the automatic support of the outrigger without manual operation. Starting the LED light 406 can illuminate the inside of the protective frame 401, and the position collector 405 can identify the bubble position inside the liquid bubble indicator 403. The position of the bubble is determined by an algorithm. The position collector 405 is a prior art and will not be described in detail. When the bubble inside the liquid bubble indicator 403 is located between the two marking lines 404, it indicates that the heights of both ends of the mounting beam 1 are the same and the RV remains horizontal. When the bubble is not between the two marking lines 404, the position collector 405 transmits a signal to the motor 207 of the leg in the direction of the bubble offset through the control system, so that the motor 207 continues to drive the telescopic leg 201 to extend downward, thereby increasing the height of the leg on this side, until the bubble is located between the two marking lines 404, thereby completing the automatic leveling of the leg.
