Description

Technical Field

[0001] This utility model relates to the field of trailer technology, and more specifically, to a multi-functional travel trailer. Background Technology

[0002] A tow truck is typically attached to the rear of a tractor unit and can be used for travel, engineering maintenance, emergency rescue, and other fields. Currently, with increasingly stressful urban life, people tend to seek relaxation in nature during their leisure time. For example, people can use a tractor unit to attach a caravan (a type of tow truck) for outdoor camping. However, currently used caravans are limited by lane width, restricting their width. This is generally achieved by lengthening the tow truck, which obviously results in the caravan occupying a large space, increasing traffic restrictions, and causing inconvenience. This utility model proposes a new solution to these problems. Utility Model Content

[0026] L-shaped guide grooves 8 are symmetrically arranged on the upper and lower sides of the connection port between the front expansion compartment 5 and the carriage 4. A partition 9 is inserted into the L-shaped guide groove 8. The partition 9 divides the carriage 4 and the front expansion compartment 5 into relatively independent spaces. A locking mechanism 10 is provided on the L-shaped guide groove 8. The working end of the locking mechanism 10 is inserted into the partition 9.

[0027] The side extension compartment 6 is inserted into the vehicle body 1, and a bottom support mechanism 11 is provided inside the vehicle body 1. The movable end of the bottom support mechanism 11 is installed at the bottom of the side extension compartment 6. A light-transmitting glass window 12 is provided on the outside of the side extension compartment 6. An openable window sash 13 is provided on the light-transmitting glass window 12. A protective plate 14 is connected to the top of the outside of the light-transmitting glass window 12 by a hinge. A support rod 15 is rotatably connected to the bottom of the inner side of the protective plate 14. An insertion hole 16 is provided on the frame of the light-transmitting glass window 12. The insertion hole 16 is configured to cooperate with the support rod 15.

[0028] The bottom of the carriage 4 is symmetrically equipped with storage cabinets 17, and drawers 18 are provided on the rear end face of the storage cabinets 17. A folding bed board 19 is also placed in the carriage 4.

[0029] The design of the front extension compartment 5 and the side extension compartment 6 increases the usable space of the carriage 4. In particular, after the vehicle body 1 is parked, the users can temporarily live in the carriage 4, which has more space and is more comfortable. During the vehicle's operation, the side extension compartment 6 is stored in the carriage 4, making the space occupied by the vehicle smaller and reducing traffic restrictions.

[0030] In this embodiment, the locking mechanism 10 includes a locking rod 1001, a handle 1002, a spring 1003, a mounting base 1004, and a bar-shaped lock head 1005. The mounting base 1004 is fixed on the L-shaped guide groove 8. The locking rod 1001 passes through the mounting base 1004 and the L-shaped guide groove 8, and the locking rod 1001 is rotatably connected to the mounting base 1004. The handle 1002 is fixed to one end of the locking rod 1001. The spring 1003 is sleeved on the locking rod 1001, and one end of the spring 1003 is rotatably connected to the mounting base 1004. On the base 1004, the other end of the spring 1003 is fixed to the locking rod 1001, and the bar-shaped lock head 1005 is fixed to the other end of the locking rod 1001. A bar-shaped lock groove 20 is provided on the partition 9 corresponding to the position of the bar-shaped lock head 1005. A bar-shaped lock groove 21 is provided on the inner side of the L-shaped guide groove 8. The bar-shaped lock groove 20 and the bar-shaped lock groove 21 form a 90° angle. By pulling and rotating the locking rod 1001, the locking mechanism 10 is opened, thereby pulling the partition 9, which facilitates the disassembly and installation of the partition 9.

[0031] In this embodiment, a handle 22 is provided on the partition 9; the handle 22 facilitates the operation of the partition 9.

[0032] In this embodiment, the bottom support mechanism 11 includes a diagonal brace 1101, a base 1102, and a top seat 1103. The base 1102 is fixed on the carriage 4, and the top seat 1103 is slidably connected to the bottom of the side extension compartment 6. The bottom spherical joint of the diagonal brace 1101 is connected to the base 1102, and the top spherical joint of the diagonal brace 1101 is connected to the top seat 1103. When the side extension compartment 6 is pulled outward and is in the open state, the top seat 1103 slides, and the diagonal brace 1101 supports the bottom of the side extension compartment 6.

[0033] In this embodiment, a hanging ring 23 is provided on the top of the side expansion compartment 6, and a luggage rack 24 is fixed on the top of the vehicle body 1. The luggage rack 24 can be used to place luggage. When the side expansion compartment 6 is pulled outward and in the open state, one end of a rope can be tied to the luggage rack 24 and the other end of the rope can be tied to the hanging ring 23. The rope, in conjunction with the bottom support mechanism 11, supports the side expansion compartment 6, increasing the safety of use.

[0034] In this embodiment, ladders 25 are symmetrically arranged on the left and right side walls of the vehicle body 1, and the top of the ladders 25 is fixedly connected to the luggage rack 24; items can be conveniently placed on the luggage rack 24 through the ladders 25.

[0035] In this embodiment, the inside of the side extension compartment 6 is connected to the storage cabinet 17 via a buckle 26; the buckle 26 ensures that the side extension compartment 6 will not be thrown out of the compartment 4 during driving.

[0036] The working process of this utility model is as follows:

[0037] Once the vehicle is stationary, when needed, open door 7, remove the folding bed board 19, open the buckle 26, and pull out the side extension compartment 6. After the side extension compartment 6 is pulled out, unfold the folding bed board 19 and place it in the area formed by the carriage 4 and the side extension compartment 6. Then, tie one end of the rope to the luggage rack 24 and the other end of the rope to the hanging ring 23. The rope, in conjunction with the bottom support mechanism 11, supports the side extension compartment 6. At this time, the vehicle can be used for users to sleep and rest. Before starting the vehicle, simply reset all components. The design of the front extension compartment 5 and the side extension compartment 6 increases the usable space of the carriage 4. Especially after the vehicle body 1 is parked, the user can temporarily live in the carriage 4, which provides more space and greater comfort. During vehicle operation, the side extension compartment 6 is stored inside the carriage 4, making the space occupied during vehicle operation smaller and reducing traffic restrictions.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
