The RV body is installed on the chassis of the RV, and bedding, refrigerator, cabinet air conditioner, TV, stereo and other furniture and electrical appliances are installed inside the RV body;

[0003] Among them, in order to ensure the stability of the RV itself during the situation, people usually need to consider that the bearing capacity of the left and right sides of the RV is basically the same when installing furniture and electrical appliances. When the bearing capacity of the left and right sides of the RV is similar, the stability of the RV during driving will be better;

[0004] However, in the actual use of RVs, when people travel, they need to prepare a lot of supplies with them, considering the different places they travel to. When the supplies with them are piled up in the storage room inside the RV, because the storage room inside the RV is usually set on the left or right side of the RV, when a large amount of supplies with them are piled up in the storage room, the left-right balance of the RV itself will be destroyed. When the left-right balance in the RV is destroyed, when the RV is driving and turning, the body of the car tends to tilt to the heavier side, which will affect driving safety to a certain extent.

[0005] Therefore, it is necessary to design a self-balancing device for balancing the gravity on the left and right sides of the RV box body. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be combined with the technical solution in the embodiments of the utility model for a clear and complete description. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] refer to Figure 1-4 As shown, it includes a motorhome floor 1, which is composed of a plurality of cross beams 11 and longitudinal beams 12. A trough body 2 is retained on both sides of the motorhome floor 1. A plurality of balancing components 3 are arranged at the bottom of the motorhome floor 1, and the balancing components 3 are located on both sides of the trough body 2. The balancing component 3 includes a mounting plate 31, and an adjusting component 32 is fixedly installed at the bottom of the mounting plate 31. The adjusting component 32 includes a motor 321 connected to the bottom of the mounting plate 31, and a screw rod 322 is connected to the output end of the motor 321. A screw rod nut 323 is matched with the outside of the screw rod 322. Two symmetrically arranged slide grooves 324 are provided at the bottom of the screw rod nut 323, and auxiliary components 33 are matched in the two slide grooves 324. The two auxiliary components 33 are connected to the bottom of the mounting plate 31, and a hook 325 for suspending a gravity member is provided at the bottom of the screw rod nut 323, and the hook 325 is located between the two auxiliary components 33.

[0024] A balancing assembly 3 is provided at the bottom of the RV floor 1, wherein the output end of the motor 321 in the balancing assembly 3 can drive the screw rod 322 to rotate, and during the rotation of the screw rod 322, the screw nut 323 will move linearly along the screw rod 322, and the screw nut 323 will gradually drive the gravity weight to the edge of the RV floor 1 during the movement, wherein the gravity weight can be used to perform gravity ratio on the left or right side of the RV, so that the gravity on the left and right sides of the RV is relatively within the same or similar range, thereby ensuring the stability of the RV itself during driving;

[0025] In this embodiment, when the gravity weight is not in use, the gravity weight will be on the central axis of the RV floor 1, and the gravity weight beside the central axis will not only not affect the weight on the left and right sides of the RV floor 1, but will also increase the weight at the central axis of the RV floor 1, and the increased weight in the middle of the RV will not affect the left and right balance of the RV, and when the gravity weight gradually moves away from the central axis, the weight will be increased on the side opposite to the direction of movement of the gravity weight;

[0026] In this embodiment, the setting of the hook 325 can be used to suspend and fix the gravity weight. Among them, the gravity weight is fixed by hanging, which can be convenient for users to replace the gravity weight, so that gravity weights of different weights can be used to ensure the balancing of the RV.

[0027] Preferably, reference Figure 3 and Figure 4 The auxiliary component 33 includes at least two connecting rods 331, the inner sides of the two connecting rods 331 are provided with support rods 332, the top of the support rods is provided with an auxiliary track 333 that matches the slide groove 324, the inner side of the connecting rod 331 is provided with an inclined support plate 334, and the other end of the inclined support plate 334 is connected to the bottom of the connecting rod 331;

[0028] The setting of the auxiliary component 33 can support the downward gravity of the screw nut 323 and make the sliding of the screw rod 322 more precise. Specifically, the slide rail set on the support rod 332 cooperates with the slide groove 324 opened on the screw nut 323, which can not only limit the sliding range of the gravity weight, but also make the sliding of the gravity weight more stable; the setting of the connecting rod 331 can provide a basis for the installation of the support rod 332 and the slide rail, and the support rod 332 cooperates with the inclined support plate 334 to disperse the downward gravity of the screw nut 323 and realize multi-point support of the screw nut 323. The multi-point support design can effectively reduce the force of the gravity weight on the screw rod 322, thereby protecting the screw rod 322 and increasing the service life of the screw rod 322.

[0029] It should be noted that due to the setting of the gravity weight, when the gravity weight is hung, the gravity of the gravity weight itself will act on the screw nut 323, which will cause the gravity of the screw nut 323 to increase. The auxiliary component 33 is mainly used to support the lower end of the screw nut 323 and protect the screw 322.

[0030] Preferably, limit blocks 34 are provided on both sides of the bottom of the mounting plate 31, and an inner groove 341 is provided on the limit block 34 for the end of the screw rod 322 to be inserted. The setting of the limit block 34 can limit the movement range of the screw rod nut 323, and the inner setting can provide a basis for the installation of the other end of the screw rod nut 323, thereby ensuring the use of the screw rod 322.

[0031] Preferably, two blocking blocks 35 are arranged on the top of the support rod 332 , and the two blocking blocks 35 are respectively connected to the two ends of the slide rail. The setting of the blocking blocks 35 can further limit the sliding limit of the screw nut 323 .

[0032] Preferably, reference Figure 2 There are four balancing components 3. The advantage of adopting four balancing components 3 is that the stability of the unilateral or bilateral counterweights of the RV can be achieved; specifically, the four balancing components 3 are respectively arranged on both sides of the two trough bodies 2, and the retention of the trough bodies 2 provides a basis for the installation of the wheels. By counterweighting both sides of the vehicle, the gravity of the counterweights will act on the wheels, which can further increase the grip of the vehicle itself and increase the stability of the vehicle during driving.

[0033] Preferably, reference Figure 1The top of the mounting plate 31 is connected with a plurality of reinforcing beams 4, and the plurality of reinforcing beams 4 are located between the two cross beams 11 close to the groove. The arrangement of the reinforcing beams 4 can fix the middle position of the top of the mounting plate 31, which can not only avoid the occurrence of the bare phenomenon above the mounting plate 31, but also increase the force strength of the mounting plate 31 after installation.

[0034] For those that require instructions, the power supply and opening and closing control technologies for the electric motor are all existing technologies, so they are not described in detail in this application document. For example, connecting the electric motor to the battery of the RV and controlling the electric motor wirelessly or by wire are all existing technologies.

[0035] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
