Technical Problem

[0005]常见扩展舱体因为要能够从主舱体的内部滑动至两侧,为了确保扩展舱体外展后的稳定性,一般都会在扩展舱体的底部增加多根支撑用的工字钢,且该工字钢还需要能够滑动装配于主舱体的地板上,故而主舱体的地板上必须开设适配工字钢滑动的滑槽,当扩展舱体收纳时上述滑槽还能被工字钢适当遮挡,但是当扩展舱体外展后,上述滑槽会直接与外界连通,密封性非常差,不仅透光、透风影响使用者休息睡眠等,舱体内部开空调调节室温时,还会造成制冷/制热效果不佳

Benefits of technology

[0018] When the expansion box is in the retracted state, the sealing component, along with the I-beam and roller guide rail assembly, is concealed in the installation cavity under the floor. When the expansion box is in the extended state, the roller guide rail assembly drives the I-beam and sealing component to slide outward together. The sealing component then slides against the lower surface of the floor until it covers and seals the groove on the floor, significantly improving the sealing performance and effectively preventing light and air leakage. This can improve the user's rest and sleep environment. Furthermore, when the air conditioner is turned on inside the main compartment to regulate the room temperature, it can effectively prevent cold or hot air from escaping from the groove, indirectly improving the cooling/heating effect inside the cabin.

Description

Technical Field

[0001] This application relates to the field of camper vehicle structure technology, and in particular to a camper vehicle extension compartment with a ground-mounted, interlocking sealing mechanism. Background Technology

[0002] Camping vans are used for picnics or outings, providing high-quality sleeping spaces, comfortable living and sleeping environments, and leisure areas for multiple people camping in the wild. Custom-designed camping vans for specific industries integrate personnel transportation and rest. This model effectively solves the contradiction between the limited passenger capacity of all-sleeper vans and the inconvenience of rest in all-seat vans, perfectly meeting the needs of military and police systems and improving the comfort of transportation and camping. When using camping vans, the issue of vehicle expansion needs to be considered.

[0003] For example, Chinese patent application number CN201621315428.6 discloses a new type of camping vehicle, including a chassis of a Class II vehicle. A main cabin is provided on the chassis. The main cabin is divided into a front living area, a middle rest area, and a rear working area. The middle rest area includes a part of the main cabin and left and right extension cabins on both sides of the main cabin. The middle rest area is equipped with multiple folding beds and a bedside table next to each folding bed. Extension mechanisms are provided on both sides of the main cabin near the rear of the chassis. The main cabin is extended to the left and right extension cabins through the extension mechanisms. Side support legs are provided below the left and right extension cabins.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist:

[0005] Because common extendable cabins need to slide from inside the main cabin to the sides, multiple supporting I-beams are usually added to the bottom of the extendable cabin to ensure stability after it extends. These I-beams also need to be able to slide onto the floor of the main cabin. Therefore, the floor of the main cabin must have grooves to accommodate the sliding of the I-beams. When the extendable cabin is stored, these grooves can be partially covered by the I-beams. However, when the extendable cabin extends, these grooves will be directly connected to the outside, resulting in very poor sealing. This not only allows light and air to pass through, affecting the user's rest and sleep, but also causes poor cooling / heating performance when the air conditioner is turned on inside the cabin to regulate the room temperature. Utility Model Content

[0006] This application provides a trench-mounted, interlocking extended compartment for a campervan to address the following technical issues:

[0007] The floor of a typical main cabin must have a sliding groove for the I-beams to slide. When the extended cabin is extended, the above-mentioned groove will be directly connected to the outside, resulting in very poor sealing. Not only does it allow light and air to pass through, affecting the user's rest and sleep, but it will also cause poor cooling / heating performance when the air conditioner is turned on inside the cabin to regulate the room temperature.

[0008] This application provides a trench-type, interlocking, and sealable extended compartment for a camping vehicle, employing the following technical solution:

[0009] A type of extendable camper van with a ground-mounted, interlocking design includes a main body and two sets of extension boxes. The main body has notches on both sides in its width direction. A horizontally arranged floor is located at the bottom of the main body, flush with the bottom of the notches. An installation cavity is formed between the floor and the inner bottom wall of the main body. A roller guide rail assembly is installed within the installation cavity. The two sets of extension boxes are slidably mounted on both sides of the main body in its width direction via the roller guide rail assembly. Multiple horizontally arranged I-beams are spaced apart between the bottom of each extension box and the roller guide rail assembly. A sliding groove is provided on the floor for the I-beams to slide. A horizontally arranged sealing component is connected to the inner end of each I-beam. When the extension box is extended outwards, the sealing component slides along with the I-beams and covers the sliding groove from the bottom.

[0010] In one feasible technical solution of this application, the sealing assembly includes a connecting seat and a strip sealing plate, the ends of the connecting seat and the strip sealing plate are fixedly connected, and the connecting seat is detachably assembled with the inner end of the I-beam.

[0011] In one feasible technical solution of this application, the connecting seat includes an L-shaped connecting plate and a bolt group. The inner end of the web of the I-beam is provided with a vertically arranged oval hole. The L-shaped connecting plate is provided with a hole through which the bolt group passes. The bolt group passes through the hole and the oval hole in sequence and clamps and fixes the L-shaped connecting plate and the web of the I-beam.

[0012] In one feasible technical solution of this application, the cross-section of the strip sealing plate is U-shaped, and the opening of the strip sealing plate is arranged downwards.

[0013] In one feasible technical solution of this application, a horizontally arranged reinforcing plate is welded to the lower opening at the inner end, the lower opening at the middle part, and the lower opening at the outer end of the strip-shaped sealing plate.

[0014] In one feasible technical solution of this application, the floor is a bamboo plywood or a wooden board, and aluminum alloy edging profiles are snapped onto both sides of the sliding groove.

[0015] In one feasible technical solution of this application, the roller guide rail assembly includes multiple sets of rollers arranged at intervals, a sliding rail and a roller mounting beam. The sliding rail is arranged horizontally and fixed to the lower surface of the I-beam. The sliding rail is an I-beam structure. The roller sets are rotatably mounted on the roller mounting beam. The roller sets roll freely between the upper and lower flanges of the sliding rail.

[0016] In one feasible technical solution of this application, the two corresponding I-beams at the bottom of the two sets of expansion boxes are staggered, that is, the two corresponding sliding grooves on the left and right are staggered and parallel to avoid mutual interference between the two adjacent sets of sealing components when they are not extended.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When the expansion box is in the retracted state, the sealing component, along with the I-beam and roller guide rail assembly, is concealed in the installation cavity under the floor. When the expansion box is in the extended state, the roller guide rail assembly drives the I-beam and sealing component to slide outward together. The sealing component then slides against the lower surface of the floor until it covers and seals the groove on the floor, significantly improving the sealing performance and effectively preventing light and air leakage. This can improve the user's rest and sleep environment. Furthermore, when the air conditioner is turned on inside the main compartment to regulate the room temperature, it can effectively prevent cold or hot air from escaping from the groove, indirectly improving the cooling / heating effect inside the cabin.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses an extended compartment for a trench-type camping vehicle with a linked, sealable design. (See also...) Figure 1-6 The ground-mounted, interlocking, and sealing-type camping vehicle extension compartment includes a main body 1 and two sets of extension boxes 2. The main body 1 has notches on both sides in the width direction. The bottom of the main body 1 has a horizontally arranged floor 3, which is flush with the bottom of the notches. An installation cavity is provided between the floor 3 and the inner bottom wall of the main body 1. A roller guide rail assembly 4 is provided in the installation cavity. The two sets of extension boxes 2 are slidably mounted on both sides of the main body 1 in the width direction via the roller guide rail assembly 4. Multiple horizontally arranged I-beams 5 are spaced apart between the bottom of the extension box 2 and the roller guide rail assembly 4. The floor 3 has a sliding groove 31 for the I-beams 5 to slide. The inner end of the I-beams 5 is also connected to a horizontally arranged sealing component 6. When the extension box 2 is unfolded outward, the sealing component 6 slides along with the I-beams 5 and blocks the sliding groove 31 from the bottom.

[0039] The two sets of expansion boxes 2 are staggered between the corresponding two I-beams 5 at the bottom (see...). Figure 4 That is, the two corresponding sliding grooves 31 on the left and right are staggered and parallel to avoid the two adjacent sets of sealing components 6 from colliding and interfering with each other when they are not extended.

[0040] In this embodiment, the sealing assembly 6 includes a connecting seat 61 and a strip-shaped sealing plate 62. The ends of the connecting seat 61 and the strip-shaped sealing plate 62 are fixedly connected, and the connecting seat 61 is detachably assembled with the inner end of the I-beam 5. The connecting seat 61 includes an L-shaped connecting plate 611 and a bolt assembly 612. The inner end of the web of the I-beam 5 is provided with a vertically arranged oval hole 51. The L-shaped connecting plate 611 is provided with a hole for the bolt assembly 612 to pass through. The bolt assembly 612 passes through the hole and the oval hole 51 in sequence and clamps and fixes the L-shaped connecting plate 611 and the web of the I-beam 5.

[0041] Furthermore, the strip sealing plate 62 has a U-shaped cross-section, and the opening of the strip sealing plate 62 is arranged downwards. A horizontally arranged reinforcing plate 63 is welded to the lower opening at the inner end, the lower opening at the middle part, and the lower opening at the outer end of the strip sealing plate 62.

[0042] The sealing component 6 designed above has a simple and robust structure, is not easily bent or deformed under gravity, is easy and stable to install, and has a good sealing effect on the slide groove 31.

[0043] The floor 3 is made of bamboo plywood or wood board. To prevent the I-beam 5 from contacting and rubbing against and damaging the bamboo plywood or wood board during repeated sliding, aluminum alloy edging profiles 32 are snapped onto both sides of the slide groove 31.

[0044] In this embodiment, the roller guide rail assembly 4 includes multiple sets of spaced roller assemblies 41, sliding rails 42, and roller mounting beams 43. The sliding rails 42 are horizontally arranged and fixed to the lower surface of the I-beam 5. The sliding rails 42 are I-beam structures. The roller assemblies 41 are rotatably mounted on the roller mounting beams 43, and the roller assemblies 41 roll freely between the upper and lower flanges of the sliding rails 42. The roller guide rail assembly 4 designed above operates stably, has a significant guiding effect, and is less likely to cause the expansion box 2 to deviate or shake during frequent sliding.

[0045] The beneficial technical effects of the trench-linkable sealing type extended car body of the camping vehicle according to the embodiments of this application are roughly as follows:

[0046] When the expansion box 2 is in the retracted state, the sealing component 6, together with the I-beam 5 and the roller guide rail assembly 4, is stored in the installation cavity under the floor 3. When the expansion box 2 is in the extended state, the roller guide rail assembly 4 drives the I-beam 5 and the sealing component 6 to slide outward together. Then, the sealing component 6 slides against the lower surface of the floor 3 until it covers and seals the groove 31 on the floor 3. The sealing performance is significantly improved, effectively preventing light and air leakage. This can improve the rest and sleep environment for users. In addition, when the air conditioner is turned on to adjust the room temperature inside the main box 1, it can also effectively prevent cold or hot air from escaping from the groove 31, indirectly improving the cooling / heating effect inside the car.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
