Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, and in particular to a chassis and a complete vehicle of an extended-range trailer recreational vehicle. Background Art

[0002] With the improvement of social productivity and the growth of people's living standards, the use of RVs is increasing. RVs are a combination of the functions of a house and a car.

They are very suitable for use in travel, location shooting, temporary accommodation, etc., and can provide greater convenience.

[0003] The Chinese utility model patent with publication number CN216102395U discloses a RV chassis frame. When the RV is driving, the stabilizing device retracts the output end, the output end is separated from the top frame, and the top frame is supported by the shock-absorbing device. The top frame can be shock-absorbed by the shock-absorbing device. The pulleys 2-1 around the top frame slide up and down in the slide rail 6-1, and the baffle blocks the horizontal displacement of the top frame, so that the top frame can effectively absorb shock and prevent damage to items inside the RV or even danger; when the RV is parked, the stabilizing device extends the output end, and the output end contacts the top frame, bearing the weight of the top frame and the RV compartment, so that the shock-absorbing device is not subjected to force and will not absorb shock, thereby extending the service life of the shock-absorbing device.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, a chassis of a range-extended trailer caravan comprises: a chassis body 1, a moving assembly arranged at the bottom of the chassis body 1 for realizing the towing movement of the chassis body 1, and a plurality of energy storage batteries 2 and a plurality of translation assemblies arranged inside the chassis body 1; a range extender 21 for realizing the charging function of the energy storage battery 2 is arranged inside the chassis body 1; the translation assembly comprises: an opening and closing plate 3 arranged on one side of the chassis body 1, a plurality of fixing plates 31 fixed on the inner side of the chassis body 1, and a plurality of fixing plates 31 arranged on the plurality of fixing plates 31. 1; a rotating shaft 33 is rotatably connected to the fixed plate 31, a gear 34 is fixed to one end of the rotating shaft 33 facing the translation plate 32, and a plurality of teeth 35 are fixed to the top of the translation plate 32 near one side; the top of the translation plate 32 is fixed to the bottom of the energy storage battery 2, the gear 34 is engaged with the plurality of teeth 35, a power source for providing rotational force to the rotating shaft 33 is provided between adjacent fixed plates 31, and a sliding member for providing sliding limit when the translation plate 32 moves is provided at the bottom of the translation plate 32.

[0030] It should be noted that the range extender 21 is composed of a generator and an engine. The generator is electrically connected to the energy storage battery 2, and the engine is electrically connected to the generator. The range extender 21 is used to charge the energy storage battery 2, thereby improving the endurance of the energy storage battery 2 and ensuring the power supply efficiency of the RV. A number of teeth 35 are evenly distributed on the top of the translation plate 32 in a linear array. After the energy storage battery 2 is fixed on the translation plate 32 located between the number of fixed plates 31, the opening and closing plate 3 is closed on one side of the chassis body 1, and the enclosed space can be used to provide storage and protection space for the energy storage battery 2. When needed When the energy storage battery 2 is stored and repaired, the opening and closing plate 3 is flipped to one side of the chassis body 1 and opened. The rotating shaft 33 is driven to rotate by the power source, which can drive the gears 34 at both ends of the rotating shaft 33 to rotate synchronously. Since the gear 34 is engaged with the several teeth 35 on the top of the translation plate 32, when the gear 34 rotates, the translation plate 32 can be driven to translate toward the outside of the chassis body 1. With the cooperation of the sliding part, the translation plate 32 and the energy storage battery 2 on the top can be smoothly moved out, thereby facilitating the energy storage and repair operations for the energy storage battery 2, thereby improving practicality.

[0044] It should be noted that the power system and power system in the whole vehicle are electrically connected to several energy storage batteries 2 respectively, and the connection between the power system and the power system and the energy storage battery 2, voltage conversion, etc. all adopt the system structure of the existing technology. For example, the connection between the power system and the energy storage battery 2 requires the use of inverters, transformers, etc., which will not be described in detail here; after the power system and power system in the whole vehicle are electrically connected to several energy storage batteries 2 respectively, on the one hand, it can provide daily electricity for daily necessities in the RV, and on the other hand, it can also provide power for the new energy RV, thereby increasing its cruising range.

[0045] When the present invention is used, after the energy storage battery 2 is fixed on the translation plate 32 located between the plurality of fixed plates 31, the groove 6 is manually pulled, and the bottom of the opening and closing plate 3 can be driven to close on one side of the chassis body 1 with the hinge point on one side of the chassis body 1 as the center of the circle, so that the enclosed space can be used to provide storage and protection space for the energy storage battery 2. When the energy storage battery 2 needs to be stored and repaired, the opening and closing plate 3 is flipped to one side of the chassis body 1 and opened, and the servo motor 4 is started to drive the worm 41 at the output end to rotate. Since the worm gear 42 is engaged with the worm gear 41, the worm gear 42 and the inner fixed shaft 33 can be driven to rotate, and the gears 34 at both ends of the shaft 33 can be driven to rotate synchronously. Since the gear 34 is engaged with the plurality of gears at the top of the translation plate 32 The teeth 35 are engaged, and when the gear 34 rotates, the translation plate 32 can be driven to translate toward the outside of the chassis body 1.
