[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0022] Combined with Figures 1 to 4 As shown, this embodiment provides an expansion compartment device, including a main body 1, an expansion compartment 2 slidably engaged with the expansion channel of the main body 1, and a driving mechanism 3 for driving the expansion compartment 2 to slide back and forth along the length direction of the expansion channel 21; preferably, taking a motorhome as an example, the main body 1 in this embodiment can be understood as the compartment of the motorhome, or can be understood as an independent expansion compartment module installed in the motorhome compartment.

[0023] More specifically, in this embodiment, water guide grooves 11 are provided along the length direction on the opposite sides of the lower bottom surface of the expansion channel 21 opened in the main body 1. One end of the water guide groove 11 facing the inner port of the expansion channel 21 is closed, that is, a water baffle 14 is provided at one end of the water guide groove 11 facing the inner port of the expansion channel 21. In this way, when the expansion compartment 2 is unfolded and rainwater seeps into the water guide groove 11 along the expansion compartment 2, the rainwater can flow out of the water guide groove 11 unidirectionally along the water guide groove 11, thereby effectively preventing the rainwater from flowing towards the inner port end of the expansion channel 21.

[0024] Further preferably, in order to prevent rainwater from seeping in after the expansion compartment 2 is retracted, in this embodiment, a sealing strip 4 is provided at the edge of the outer port of the expansion channel 21. Specifically, a receiving groove is provided at the edge of the outer port of the expansion channel 21, and the sealing strip 4 is embedded in the receiving groove. Further, in order to facilitate the rainwater flowing into the water guide groove 11 to flow out, a gap is provided between the end face of the sealing strip 4 and one side wall of the water guide groove 11 in this embodiment.

[0025] Furthermore, in order to prevent the expansion compartment 2 from detaching from the main body 1 and also to play a certain water blocking effect after the expansion compartment 2 is unfolded, in this embodiment, a limiting flange 22 extends outwards at the edge of the opening end of the expansion compartment 2, and the limiting flange 22 is matched with the end face of the inner port of the expansion channel 21.

[0026] In addition, in order to facilitate the sliding connection between the expansion compartment 2 and the main body 1, in this embodiment, protrusions 23 are provided along the length direction on the opposite sides of the lower bottom surface of the expansion compartment 2 and are matched with the water guide grooves 11. A multi-stage slide rail 5 is provided between the protrusions 23 and the opposite side walls of the water guide grooves 11 to realize the retraction and expansion of the expansion compartment 2. Preferably, in order to prevent the rainwater in the water guide groove 11 from soaking the multi-stage slide rail 5 and causing damage to the multi-stage slide rail 5, a gap is provided between the multi-stage slide rail 5 and the lower bottom surface of the water guide groove 11 in this embodiment, and this gap can effectively prevent the rainwater seeping into the water guide groove 11 from soaking the multi-stage slide rail 5.

[0027] Furthermore, in order to realize the automatic retraction and extension of the expansion chamber 2, the lower bottom surface of the expansion channel 21 in this embodiment is provided with a first storage chamber 12 along the width direction, and a driving mechanism 3 is set in the first storage chamber 12. Specifically, the driving mechanism 3 is set along the width direction of the lower bottom surface of the expansion channel 21, and the driving mechanism 3 includes a motor 31, a transmission shaft 32 fastened to the driving shaft of the motor 31, and gears 33 set at both ends of the transmission shaft 32. Furthermore, racks meshing with the corresponding gears 33 are set on opposite sides of the lower bottom surface of the expansion chamber 2 along the length direction. In this way, the expansion chamber 2 is driven to move back and forth along the expansion channel 21 by the drive of the motor 31.

[0028] In addition, in order to facilitate the positioning of the expansion chamber 2 and prevent movement between the main body 1 during driving, the present embodiment is provided with a plurality of positioning holes 13 at the front and rear ends of the two side walls of the expansion channel 21, and the positioning holes 13 cooperate with the positioning mechanism provided on the side wall of the expansion chamber 2. Preferably, the positioning mechanism in the present embodiment can be set as a lock such as an electromagnetic lock or a manual lock, so that the lock tongue of the above lock cooperates with the positioning hole 13 to achieve the positioning of the expansion chamber 2. The specific settings of the lock are commonly used in the relevant technology and will not be described in detail here.

[0029] In the present embodiment, in order to facilitate the smooth introduction of rainwater that penetrates through the expansion bin 2 into the water gutter 11, it is preferred that a side wall of the water gutter 11 is coplanar with the vertical wall of the expansion channel 21, and the intersections of the bottom of the water gutter 11 and the vertical wall of the expansion channel 21, as well as the vertical wall of the expansion channel 21 and the horizontal wall above the expansion channel 21 are all provided with rounded corners, so as to reduce structural stress while allowing continuous bending of sealing strips of the same cross-section without cutting corners and turning, making the sealing effect of the sealing strip more reliable.

[0030] The present embodiment also provides a motorhome, including the above-mentioned expansion compartment 2 device. Preferably, the expansion compartment 2 device can be installed in the car body as a separate module, or can be slidably matched with the car body with the car body as the car body, so as to effectively improve the waterproof effect of the motorhome and then improve the user experience of the motorhome.
