Abstract
Description
Technical Field
[0001] This utility model relates to a pass-through cabin for a Type C motorhome, belonging to the field of motorhome components. Background Technology
[0002] A Class C motorhome consists of two parts: a chassis and a body. The chassis includes the main beam 3 and the driver's cab. There is a passageway between the driver's cab and the body called a drive-through compartment, which facilitates access from the living area to the driver's cab and also serves as a safety passage.
[0003] Traditional Class C motorhomes use a fixed connection between the cab and the body. During driving, uneven roads and varying elevations can cause torsional stress between the cab and the body, leading to deformation of the vehicle. This torsional stress also causes abnormal noises and deformation among the internal components, affecting the overall quality of the motorhome. Furthermore, it hinders engine ventilation and heat dissipation during driving. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a pass-through cabin for Class C motorhomes, solving the problems of connecting the driver's cab and the motorhome cabin, as well as the energy-saving issues of air conditioning after the connection.
[0005] To achieve the above objectives, the technical solution adopted by this utility model includes:
[0006] A pass-through compartment for a Class C motorhome, wherein an opening on the rear side of the driver's cab serves as a connection port to the driver's cab, and an opening on the front side of the motorhome's passenger compartment serves as a connection port to the passenger compartment.
[0007] Its features include rigid connecting compartments, flexible retractable curtains, and RV cabin connecting seats;
[0008] The RV cabin connecting seat is installed on the RV cabin connecting hole, the rigid connecting compartment is fixed on the cab connecting hole, and the flexible telescopic curtain is a rectangular tube with its front end connected to the rigid connecting compartment and its rear end connected to the RV cabin connecting seat.
[0009] The pass-through compartment for a Type C motorhome is characterized in that the rigid connecting compartment is a rectangular cylindrical structure made of metal.
[0010] According to the described through-cabin for C-type motorhomes, the motorhome cabin connecting seat is equipped with a sliding window, and the sliding window is equipped with two sets of sliding doors. When they are staggered, they close the driver's cab and the motorhome cabin, and when they overlap, they connect the motorhome cabin and the driver's cab.
[0011] According to the described pass-through compartment for a Class C motorhome, the rear side opening of the cab extends upward to the top of the cab, and the rigid connecting compartment covers the opening at the top of the rear side of the cab.
[0012] According to the described drive-through cabin for Type C motorhomes, the flexible retractable curtain has a rubber laminate structure.
[0013] According to the described pass-through compartment for a Class C motorhome, the rigid connecting compartment is welded to the cab connection hole.
[0014] The pass-through compartment for a Class C motorhome also includes a cab connecting seat, which is mounted on a cab connecting hole, and the rigid connecting compartment is fixed to the cab connecting seat.
[0015] The advantages of this utility model are:
[0016] This structure can eliminate torsional stress between the cab and the RV body, improving the stability of product quality.
[0017] This structure can eliminate abnormal noises between various components in the living area inside the RV.
[0018] Because the cab is affected by the high temperature outside in summer, the temperature inside the cab can be high. A sliding door can be used to isolate the cab from the living quarters, so that the living quarters are not affected by the high temperature and the temperature inside the living quarters can be kept constant. Air conditioning can be used to achieve energy saving.
[0019] Because the cab temperature is low in winter due to the influence of low outside temperatures, a sliding door can be used to isolate the cab from the living quarters, so that the living quarters are not affected by the low temperature and the temperature in the living quarters can be kept constant. Using a heater can achieve energy saving.
[0020] It can also serve as a safe escape route. Attached Figure Description

[0026] The specific details of this utility model are further described below:
[0027] This utility model is used for the pass-through compartment of a Type C motorhome, such as... Figure 1 The rear side opening of the cab serves as the cab connection hole, and the front side opening of the RV compartment 5 serves as the compartment connection hole. This through-cabin includes a rigid connecting compartment 1, a flexible retractable curtain 2, and an RV compartment connecting seat 4.
[0028] The RV cabin connecting seat 4 of this device is installed on the RV cabin connecting hole, the rigid connecting compartment 1 is fixed on the cab connecting hole, and the flexible telescopic curtain 2 is a rectangular tube with its front end connected to the rigid connecting compartment 1 and its rear end connected to the RV cabin connecting seat 4.
[0029] The rigid connecting compartment 1 is a rectangular cylindrical structure made of metal.
[0030] The RV cabin connecting seat 4 of this device is equipped with a sliding window 6, which has two sets of sliding doors. When staggered, the doors close the driver's cab and the RV cabin 5; when overlapping, one side is pushed open to connect the RV cabin 5 and the driver's cab. The purpose of this structure is to achieve energy conservation. When in the driver's cab, the driver's cab air conditioner can be turned on for cooling or insulation; when living in the RV cabin, the living area air conditioner can be turned on for cooling or insulation.
[0031] The opening on the rear side of the cab extends upward to the top of the cab, and the rigid connecting compartment 1 covers the opening at the top of the rear side of the cab.
[0032] The flexible telescopic curtain 2 of this device has a rubber layered structure. When there is a slight relative displacement between the cab and the RV compartment, the flexible telescopic curtain 2 can stretch with the distance between the two, avoiding damage, deformation and misalignment caused by hard connection.
[0033] The rigid connecting compartment 1 of this device is fixed by welding to the cab connection hole, or by setting a cab connection seat on the cab connection hole, with the cab connection seat installed on the cab connection hole and the rigid connecting compartment 1 fixed on the cab connection seat. After connection, the gap between the rigid connecting compartment 1 and the cab should be sealed to prevent air and water leakage.
[0034] This device is used in Class C motorhomes for connecting the driver's cab and the motorhome body. It employs a flexible connection between the connecting compartment 5 and the body to eliminate torsional stress between the cab and the body, improving product quality and stability. A sliding door separates the driver's cab from the living area, promoting energy conservation during motorhome use. It also eliminates noise between the motorhome body and the driver's cab and serves as a safe escape route.
