Technical Field
[0001] The utility model relates to the technical field of recreational vehicles, in particular to a sealing and waterproof structure for a side expansion space of a recreational vehicle. Background Art
[0002] A recreational vehicle, also known as a motorhome, is a mobile travel tool integrating the functions of a house and a vehicle, which has the dual attributes of a transportation means and a temporary residence, and its core is to meet people's travel needs of living while traveling. It takes a motor vehicle as the basic carrier, and the interior is integrated with basic facilities required for home life, so that short-term independent residence can be realized without relying on external supplies. Common facilities include beds for rest, kitchens for cooking (including stoves and sinks), toilets for washing, as well as power supply, water supply, heating / cooling systems. Some high-end models are also equipped with refrigerators, wardrobes, desks, etc., which can meet daily needs such as diet, sleep and washing.
[0003] When the expansion compartment of the recreational vehicle in the prior art is retracted and stored, a rigid sealing strip design is mostly adopted. When a slight change occurs in the gap due to the installation deviation of the expansion compartment, the rigid sealing strip cannot deform accordingly for fitting, which easily forms a sealing dead angle, may cause rainwater to penetrate into the interior of the recreational vehicle, and reduces its sealing effect. Contents of the Utility Model
[0004] To solve the above technical problems, the utility model provides a sealing and waterproof structure for a side expansion space of a recreational vehicle.
[0005] The utility model is realized by adopting the following technical solution: a sealing and waterproof structure for a side expansion space of a recreational vehicle, comprising a carriage, wherein a sealing assembly is arranged on the inner wall of the carriage, and a locking assembly is arranged on the inner wall of the carriage; The sealing assembly comprises a support plate, the support plate is fixedly connected to the inner wall of the carriage, a sealing groove is formed inside the support plate, a sliding groove is formed on the inner wall of the support plate, a sliding block is slidably connected to the outer wall of the sliding groove, an expansion compartment is fixedly connected to the outer wall of the sliding block, and a sealing sheet is fixedly connected to the outer wall of the expansion compartment.
[0006] Through the above technical solution, the sealing sheet on the outer wall of the expansion compartment is in close contact with the sealing groove inside the support plate, and the flexible sealing characteristic of the sealing sheet is utilized to fill the gap between the expansion compartment and the support plate, which can completely block the infiltration of rainwater and other impurities, effectively protect the internal facilities of the carriage from moisture and pollution. The flexible characteristic of the sealing sheet can adapt to the slight change of the gap, avoid the problem of poor fitting caused by rigid sealing, maintain a stable sealing effect after long-term use, and ensure the dry and clean internal living environment.
[0007] As a further improvement of the above solution, the locking assembly comprises a locking groove, the locking groove is formed inside the support plate, and a locking rod is slidably connected to the outer wall of the locking groove.
[0008] As a further improvement to the above solution, the locking rod is slidably connected inside the slider, and a fixing plate is slidably connected to the outer wall of the locking rod.
[0009] As a further improvement to the above solution, the fixing plate is fixedly connected to the bottom of the inner wall of the expansion compartment, and a limiting piece is fixedly connected to the outer wall of the end of the locking rod near the slider.
[0010] As a further improvement to the above solution, a spring is sleeved on the outer wall of the locking rod, and a push plate is fixedly connected to the outer wall of the end of the locking rod away from the limiting piece.
[0011] As a further improvement to the above solution, a fixing rod is fixedly connected inside the end of the locking rod near the push plate, and a hook is rotatably connected to the outer wall of the fixing rod.
[0012] As a further improvement to the above solution, a connecting plate is fixedly connected to the top of the fixing plate, and a support rod is fixedly connected inside the connecting plate.
[0013] Through the above technical solution, the spring recovers its elastic deformation, pushes the limiting plate to drive the locking rod to slide in the opposite direction, so that the locking rod is inserted into the corresponding locking groove, completing the position locking of the expansion compartment. This allows personnel to quickly complete the process without professional tools, with only one person required. The elastic force of the spring can provide a continuous and uniform thrust to the locking rod, making the locking rod and the locking groove fit tightly. Combined with the limiting effect of the limiting plate, it can effectively prevent the locking rod from falling off due to bumps and vibrations during vehicle operation, ensuring the absolute stability of the expansion compartment during use and avoiding safety hazards caused by displacement and shaking.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention involves pushing the expansion compartment during storage, causing its slider to slide smoothly along the groove on the inner wall of the support plate until the expansion compartment is fully retracted into the vehicle compartment. At this point, a locking component locks it in place. The sealing sheet on the outer wall of the expansion compartment fits tightly against the sealing groove inside the support plate. Utilizing the flexible sealing properties of the sealing sheet, the gap between the expansion compartment and the support plate is filled, completely preventing the infiltration of rainwater and other impurities. This effectively protects the interior facilities of the vehicle compartment from moisture and contamination. The flexible nature of the sealing sheet can adapt to slight changes in the gap, avoiding the problem of loose fit caused by rigid sealing. It can maintain a stable sealing effect even after long-term use, ensuring a dry and clean interior living environment.
[0015] This invention utilizes a push plate to drive a locking rod to slide along the inner wall of a fixed plate. The locking rod simultaneously slides within the slider and the expansion compartment, compressing a spring via a limiting plate. Once the locking rod disengages from its locking groove, the limiting state is released. The hook is then rotated, causing it to rotate around the fixed rod and attach to the outer wall of the support rod. The connecting plate and support rod maintain the locking rod in the unlocked position. After the expansion compartment is fully extended, the hook is released from the support rod, allowing the spring to regain its elasticity and push the limiting plate to drive the locking rod to slide in the opposite direction, inserting it into the corresponding locking groove. This completes the locking of the expansion compartment, eliminating the need for specialized tools and allowing for quick operation by a single person. The spring's elastic force provides a continuous and uniform thrust to the locking rod, ensuring a tight fit between the locking rod and the locking groove. Combined with the limiting plate's function, this effectively prevents the locking rod from falling off due to bumps and vibrations during vehicle operation, ensuring the expansion compartment remains absolutely stable during use and preventing safety hazards caused by displacement or shaking.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example
[0019] Please combine Figure 1-6This embodiment provides a sealed and waterproof structure for the side expansion space of a motorhome, including a vehicle compartment 1, a sealing component 2 and a locking component 3 provided on the inner wall of the vehicle compartment 1. The sealing assembly 2 includes a support plate 201, which is fixedly connected to the inner wall of the carriage 1. A sealing groove 202 is provided inside the support plate 201, and a sliding groove 203 is provided on the inner wall of the support plate 201. A slider 204 is slidably connected to the outer wall of the sliding groove 203. An expansion compartment 205 is fixedly connected to the outer wall of the slider 204, and a sealing sheet 206 is fixedly connected to the outer wall of the expansion compartment 205.
[0020] Pushing the expansion compartment 205 causes the slider 204 to slide smoothly along the groove 203 on the inner wall of the support plate 201 until the expansion compartment 205 is stored inside the carriage 1. At this time, the locking component 3 locks it. The sealing plate 206 on the outer wall of the expansion compartment 205 fits tightly with the sealing groove 202 inside the support plate 201. Utilizing the flexible sealing characteristics of the sealing plate 206, the gap between the expansion compartment 205 and the support plate 201 is filled, which can completely block the infiltration of rainwater and other impurities, effectively protecting the internal facilities of the carriage 1 from moisture and pollution. The flexible characteristics of the sealing plate 206 can adapt to the slight changes in the gap, avoiding the problem of loose fit caused by rigid sealing. It can still maintain a stable sealing effect after long-term use, ensuring the dryness and cleanliness of the internal living environment.
[0021] The locking component 3 includes a locking groove 301, which is formed inside the support plate 201, and a locking rod 302 is slidably connected to the outer wall of the locking groove 301.
[0022] The locking rod 302 is slidably connected inside the slider 204, and the outer wall of the locking rod 302 is slidably connected to the fixing plate 303.
[0023] The fixing plate 303 is fixedly connected to the bottom of the inner wall of the expansion compartment 205, and the locking rod 302 is fixedly connected to the outer wall of the end near the slider 204 by a limiting piece 304.
[0024] A spring 305 is sleeved on the outer wall of the locking rod 302, and a push plate 306 is fixedly connected to the outer wall of the end of the locking rod 302 away from the limiting piece 304.
[0025] A fixing rod 307 is fixedly connected to the end of the locking rod 302 near the push plate 306, and a hook 308 is rotatably connected to the outer wall of the fixing rod 307.
[0026] A connecting plate 309 is fixedly connected to the top of the fixing plate 303, and a support rod 310 is fixedly connected inside the connecting plate 309.
[0027] The push plate 306 drives the locking rod 302 to slide along the inner wall of the fixed plate 303. The locking rod 302 slides synchronously inside the slider 204 and the expansion box 205. The locking rod 302 synchronously drives the limiting plate 304 to compress the spring 305. When the locking rod 302 disengages from the locking groove 301, the limiting state is released. Then, the hook 308 is rotated so that it rotates around the fixed rod 307 and hooks onto the outer wall of the support rod 310. Through the fixing action of the connecting plate 309 and the support rod 310, the locking rod 302 is kept in the unlocked position. After unfolding to the full extent, the connection between the hook 308 and the support rod 310 is released, and the spring 305 returns to its elasticity. The deformation pushes the limiting piece 304 to cause the locking rod 302 to slide in the opposite direction, so that the locking rod 302 is inserted into the corresponding locking groove 301, completing the position locking of the expansion box 205. This allows personnel to quickly complete the process without professional tools, with only one person required. The elastic force of the spring 305 provides a continuous and uniform pushing force to the locking rod 302, making the locking rod 302 tightly fitted into the locking groove 301. Combined with the limiting effect of the limiting piece 304, this effectively prevents the locking rod 302 from falling off due to bumps and vibrations during vehicle operation, ensuring the absolute stability of the expansion box 205 during use and avoiding safety hazards caused by displacement and shaking.
[0028] The implementation principle of the sealing and waterproof structure of the RV side extension space in this embodiment is as follows: When personnel need to unfold or store the RV side extension space, they first push the push plate 306 to drive the locking rod 302 to slide along the inner wall of the fixed plate 303. The locking rod 302 slides synchronously inside the slider 204 and the extension box 205. The locking rod 302 simultaneously drives the limiting plate 304 to compress the spring 305. When the locking rod 302 disengages from the locking groove 301, the limiting state is released. Then, the hook 308 is rotated so that it rotates around the fixed rod 307 and is hooked onto the outer wall of the support rod 310. The connection plate 309 is fixed to the support rod 310. To use, keep the locking lever 302 in the unlocked position. After unfolding to the full extent, disconnect the hook 308 from the support rod 310. The spring 305 returns to its elastic deformation, pushing the limiting plate 304 to cause the locking lever 302 to slide in the opposite direction, allowing the locking lever 302 to insert into the corresponding locking groove 301, thus completing the position locking of the expansion compartment 205. This allows for quick operation by a single person without the need for specialized tools. The elastic force of the spring 305 provides a continuous and uniform thrust to the locking lever 302, ensuring a tight fit between the locking lever 302 and the locking groove 301. Combined with the limiting effect of the limiting plate 304, this effectively prevents the locking lever from slipping while the vehicle is in motion. The bumps and vibrations caused the locking rod 302 to fall off, ensuring that the expansion compartment 205 is absolutely stable during use and avoiding safety hazards caused by displacement and shaking. The four locking slots 301 are set symmetrically with the support plate 201 as the center. The locking slot 301 near the middle of the compartment 1 is responsible for locking the expansion compartment 205 when it retracts, and the locking slot (301) away from the middle of the compartment (1) is responsible for locking the expansion compartment (205) when it unfolds. When the expansion compartment 205 is stored, push the expansion compartment 205 to make it drive the slider 204 to slide smoothly along the slide groove 203 on the inner wall of the support plate 201 until the expansion compartment 205 is fully extended. 05. When stored inside the compartment 1, the locking component 3 locks it in place. The sealing plate 206 on the outer wall of the expansion compartment 205 fits tightly with the sealing groove 202 inside the support plate 201. Utilizing the flexible sealing properties of the sealing plate 206, the gap between the expansion compartment 205 and the support plate 201 is filled, which can completely block the infiltration of rainwater and other impurities, effectively protecting the interior facilities of the compartment 1 from moisture and pollution. The flexible properties of the sealing plate 206 can adapt to the slight changes in the gap, avoiding the problem of loose fit caused by rigid sealing. It can maintain a stable sealing effect even after long-term use, ensuring a dry and clean internal living environment.
