Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 6 As shown, a parking support device in one embodiment of the present invention includes: a suspension 1, a folding and storage component 2, and a multi-angle support and positioning component 3.

[0031] like Figures 1 to 3 As shown, the folding and storage assembly 2 is mounted on the front end of the suspension 1. The folding and storage assembly 2 includes a drive rod 201, both ends of which are rotatably connected to the suspension 1. The drive rod 201 provides support and fixation for the fixing block 202.

[0032] It is worth noting that the actual diameter of the drive rod 201 can be adaptively adjusted according to the weight changes of the suspension 1 and the RV cabin 4, thereby ensuring the support strength of the drive rod 201.

[0033] like Figures 2 to 5 As shown, a fixing block 202 is fixedly sleeved on the outer side of the drive rod 201. The fixing block 202 serves to support and fix the gearbox 301. A drive gear 203 is fixedly connected to one end of the drive rod 201 located outside the suspension 1. The drive rod 201 is rotated by driving the drive gear 203, thereby allowing the multi-angle support and positioning assembly 3 to be folded and stored.

[0034] like Figures 2 to 5As shown, a locking bolt 204 is threadedly connected to the upper part of the drive gear 203. One end of the locking bolt 204, located inside the fixing block 202, contacts the outer surface of the drive rod 201. The fixing block 202 is locked and positioned by pressing the fixing bolt 204 against it.

[0035] like Figures 2 to 3 As shown, an assembly frame 205 is fixedly connected to the outer side of the suspension 1, and the drive rod 201 is rotatably connected to the assembly frame 205. The assembly frame 205 serves as an assembly limit for the drive rod 201. A driven gear 206 meshes with one side of the drive gear 203. The drive gear 203 is synchronously rotated by controlling the rotation of the driven gear 206.

[0036] like Figure 2 As shown, a drive shaft 207 is fixedly connected inside the driven gear 206, and the drive shaft 207 is rotatably connected to the mounting frame 205. The drive shaft 207 serves to support and fix the driven gear 206 and drive its rotation.

[0037] Specifically, in practical applications, the drive shaft 207 can be connected to an external drive handwheel or electric motor, and the driven gear 206 can be synchronously driven by rotating the drive shaft 207.

[0038] like Figures 2 to 3 As shown, the multi-angle support and positioning assembly 3 is fixedly mounted below the drive rod 201. The multi-angle support and positioning assembly 3 includes a gearbox 301, which is fixedly mounted below the fixing block 202. The gearbox 301 provides support and fixation for the fixed support column 302. At the same time, the gearbox 301 provides assembly and operating space for the worm gear 307 and the worm 308.

[0039] like Figures 2 to 3 As shown, a fixed support column 302 is fixedly connected to the lower part of the gearbox 301, and a retractable inner rod 303 is slidably fitted below the fixed support column 302. The suspension 1 can be adjusted and limited by the telescopic cooperation between the fixed support column 302 and the retractable inner rod 303.

[0040] like Figures 4 to 5 As shown, a lifting threaded rod 306 is rotatably mounted inside the fixed support 302, and the lifting threaded rod 306 is threadedly connected to the retractable inner rod 303. By controlling the rotation of the lifting threaded rod 306, the retractable inner rod 303 can move up and down with the rotation of the lifting threaded rod 306 under the action of the internal and external threads.

[0041] like Figures 4 to 5 As shown, a worm gear 307 is fixedly connected to one end of the lifting threaded rod 306 located inside the gearbox 301. The rotation of the lifting threaded rod 306 is driven by controlling the rotation of the worm gear 307.

[0042] like Figures 4 to 5 As shown, a worm 308 is meshed on one side of the worm gear 307, and both ends of the worm 308 are rotatably connected to the gearbox 301. The worm 308 drives the rotation of the worm gear 307 and locks and limits its movement.

[0043] Specifically, the lead angle of the worm 308 is smaller than the equivalent friction angle of the worm wheel 307, which enables the worm wheel 307 and the worm 308 to have a self-locking function, thereby improving the stability of the rotational drive of the lifting threaded rod 306 through the worm wheel 307 and the worm 308.

[0044] like Figure 2 As shown, a lifting handwheel 309 is fixedly connected to one end of the worm gear 308 outside the gearbox 301. The worm gear 308 is driven to rotate by controlling the rotation of the lifting handwheel 309.

[0045] like Figures 4 to 6 As shown, a guide shrinkage groove is provided at the lower end of the inner shrinkage rod 303, and the support rod 304 is inserted and assembled in the guide shrinkage groove. The guide shrinkage groove is used to guide and limit the shrinkage of the support rod 304.

[0046] like Figures 4 to 6 As shown, a support rod 304 is slidably inserted below the retractable inner rod 303. The support rod 304 serves to support, fix, and guide the lifting and lowering of the support ball seat 310.

[0047] like Figures 4 to 6 As shown, a support leg 305 is hinged to the lower end of the support rod 304. The support leg 305 provides support and limits the movement of the support rod 304.

[0048] like Figures 4 to 6 As shown, a support ball seat 310 is fixedly connected to the lower end of the support rod 304. The support ball seat 310 and the spring 311 cooperate to connect the support rod 304 and the support leg 305 in a universal joint, so that the support leg 305 can support the ground with poor flatness.

[0049] like Figures 4 to 6 As shown, a spring 311 is sleeved on the outer side of the support rod 304, and the spring 311 is arranged between the support rod 304 and the support ball seat 310. The contraction and return of the spring 311 provides support and limit for the support ball seat 310.

[0050] like Figures 4 to 6 As shown, a limiting support 312 is fixedly connected above the support leg 305, and the limiting support 312 is hinged to the support ball seat 310. The limiting support 312 limits the hinged connection between the support ball seat 310 and the support leg 305.

[0051] like Figures 4 to 6As shown, several evenly distributed positioning pins 313 are slidably inserted into the lower part of the support leg 305. By inserting the positioning pins 313 into the ground, the support leg 305 can be anti-slip and limited, thereby improving the stability of supporting the suspension 1.

[0052] like Figure 1 As shown, a motorhome includes a parking support device and a motorhome compartment 4, which is fixedly mounted above the suspension 1.

[0053] In practical use, the driven gear 206 can be driven to rotate by driving the drive shaft 207. The drive rod 201 can drive the fixed block 202 to rotate synchronously under the meshing action of the drive gear 203 and the driven gear 206. By controlling the rotation of the drive shaft 207, the fixed block 202 can drive the multi-angle support and positioning component 3 to rotate 90°, so that the multi-angle support and positioning component 3 can support and limit the drive rod 201 and the suspension 1.

[0054] Subsequently, according to the actual support height requirements, the worm gear 308 can be driven to rotate by controlling the rotation of the lifting handwheel 309. The lifting threaded rod 306 can rotate under the meshing action of the worm gear 308 and the worm wheel 307, so that the retractable inner rod 303 can move in and out under the action of the internal and external threads. Thus, the suspension 1 at different heights can be supported and limited by the cooperation of the fixed support 302 and the retractable inner rod 303.

[0055] When the outrigger 305 supports and limits the suspension 1, the outrigger 305 can provide multi-angle support for the retractable inner rod 303 through the contraction of the spring 311 and the combined action of the support ball seat 310 and the limiting support 312. In addition, depending on the ground hardness, the anti-slip performance of the outrigger 305 can be improved by inserting several positioning pins 313 at the bottom of the outrigger 305, thus ensuring the support stability of the outrigger 305.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
