Description

A modular truck body mounting structure Technical Field

[0001] This utility model relates to the field of truck body technology, and in particular to a modular truck body installation structure. Background Technology

[0002] Freight trucks, generally referred to as cargo trucks or lorries, include dump trucks, tractor-trailers, off-road trucks for off-highway and roadless areas, and various vehicles manufactured for special needs. They are primarily used for transporting goods, and sometimes also refer to vehicles capable of towing other vehicles, falling under the category of commercial vehicles. They are generally classified into heavy-duty and light-duty trucks based on their weight. The vast majority of freight trucks are powered by diesel engines, but some light-duty trucks use gasoline, LPG, or natural gas.

[0003] Most truck body structures on the market consist of a base and a body. The base is fixed to the truck body, and the body is installed on the base by welding or fasteners. However, this type of truck body structure has the following shortcomings in actual use: the installation, replacement, or maintenance of the body requires operators to use tools and equipment, which makes the entire installation and disassembly operation more labor-intensive and difficult, and inconvenient for actual use, thus reducing the convenience and efficiency of the body installation and disassembly operation.

[0004] In view of this, it is of particular importance to design and manufacture a truck body installation structure that enables tool-free quick installation and disassembly between the body and the base, thereby improving the convenience and efficiency of truck body installation and disassembly. This structure is particularly important in the design, manufacturing and practical use of truck bodies. Summary of the Invention

[0005] The purpose of this utility model is to propose a modular truck body installation structure to solve the problems of traditional truck bodies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular truck body installation structure includes a base, a body disposed on the base, and side beams symmetrically fixed to the left and right sides of the lower end of the body and interlocking with the base. A molding mechanism for tool-free fixing of the body to the base is provided between the four corners of the base and the body.

[0008] As a further description of the above technical solution:

[0009] The molding mechanism includes a fixing column fixed at the four corners of the lower end of the box body and extending downward through the base, a square locking block fixed at the lower end of the fixing column, a first square hole opened at the four corners of the base and matching the square locking block, and a rotating locking part disposed between the base, the fixing column and the square locking block.

[0010] As a further description of the above technical solution:

[0011] The rotary locking part includes rotary grooves opened at the four corners of the base and connected to the first square hole, a rotary table rotatably installed inside the rotary groove, a second square hole opened in the middle of the rotary table and corresponding to the first square hole, and a rotary handle fixed outside the rotary table and located inside the rotary groove.

[0012] As a further description of the above technical solution:

[0013] The handle and the second square hole are vertically arranged, and a locking part is provided between the handle and the base.

[0014] As a further description of the above technical solution:

[0015] The locking part includes an external stud that is screwed onto the handle, an internal threaded hole that is opened on the side of the base and corresponds to the external stud, and a knob fixed on the outer end of the external stud.

[0016] As a further description of the above technical solution:

[0017] Both the front and rear ends of the side beam are rotatably fitted with baffles covering the rotary grooves on the side facing the rotary table.

[0018] As a further description of the above technical solution:

[0019] Rubber pads are installed at the four corners of the upper end of the base, above the first square hole.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, a rotating groove, a first square hole, a rotating platform, a rotating handle, and a second square hole are provided at the four corners of the base. Simultaneously, a fixing post and a square locking block are provided at the four corners of the lower end of the body. When the rotating handle is rotated 90° outward to exit the rotating groove, the second square hole on the rotating platform can be adjusted to coincide with the first square hole on the base. At this time, the fixing post and square locking block on the body can be positioned downward and inserted between the first and second square holes. After the body and base are engaged, when the rotating handle is rotated 90° inward to return to the rotating groove, the second square hole can be rotated to be perpendicular to the first square hole and the square locking block. This prevents the body, fixing post, and square locking block from moving upward on the base. This structure enables tool-free quick installation and disassembly between the base and the body, effectively reducing the workload and difficulty of body installation and disassembly operations, thereby improving the convenience and efficiency of body installation and disassembly operations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1-3. This utility model provides a technical solution: a modular truck body installation structure, including a base 1, a body 2 set above the base 1, and side beams 201 symmetrically fixed on the left and right sides of the lower end of the body 2 and fastened to the base 1. A molding mechanism for tool-free fixing of the body 2 to the base 1 is provided between the four corners of the base 1 and the body 2.

[0029] Specifically, as shown in Figures 1-3, the molding mechanism includes a fixing post 202 fixed at the four corners of the lower end of the box body 2 and penetrating downward through the base 1, a square locking block 203 fixed at the lower end of the fixing post 202, a first square hole 102 opened at the four corners of the base 1 and matching the square locking block 203, and a rotating locking part disposed between the base 1, the fixing post 202 and the square locking block 203.

[0030] The rotary locking part includes rotary grooves 101 opened at the four corners of the base 1 and connected to the first square hole 102, a rotary table 3 rotatably installed inside the rotary groove 101, a second square hole 302 opened in the middle of the rotary table 3 and corresponding to the first square hole 102, and a rotary handle 301 fixed outside the rotary table 3 and located inside the rotary groove 101. On the one hand, it is convenient for the operator to hold and rotate the rotary table 3. On the other hand, it can form a lever structure on the rotary table 3, which can make the rotation and adjustment of the rotary table 3 more effortless.

[0031] Specifically, as shown in Figures 1-3, the handle 301 and the second square hole 302 are vertically arranged, so that when the handle 301 is rotated outward by 90°, the second square hole 302 can be rotated and adjusted to coincide with the first square hole 102, which facilitates the subsequent positioning and sliding of the fixing post 202 and the square locking block 203 into the space between the first square hole 102 and the second square hole 302. A locking part is provided between the handle 301 and the base 1. The locking part includes an outer stud 4 that is screwed onto the handle 301, an inner threaded hole 103 that is opened on the side of the base 1 and corresponds to the outer stud 4, and a knob 401 fixed on the outer end of the outer stud 4, which facilitates the operator's gripping and rotation adjustment of the outer stud 4.

[0032] Specifically, as shown in Figures 1-3, the front and rear ends of the side beam 201 are rotatably mounted with baffles 204 covering the swivel groove 101 on the side facing the rotating table 3, which can prevent the swivel groove 101 from being directly exposed to the external environment, thereby hiding and protecting the molding mechanism between the base 1 and the side beam 201.

[0033] Specifically, as shown in Figure 1, rubber pads 5 are installed at the four corners of the upper end of the base 1 above the first square hole 102. On the one hand, this can effectively reduce the rigid impact force on the base 1 when the box 2 is installed. On the other hand, it improves the stability of the base 1 and the box 2 after assembly, and can reduce the occurrence of shaking, displacement and abnormal noise after the box 2 is installed on the base 1.

[0034] Working principle: When using the truck, after the base 1 is fixed to the truck body, to install the cargo box 2 onto the truck, the operator can pre-rotate the handle 301 on the base 1 90° outward from the groove 101, and simultaneously rotate the baffle 204 between the cargo box 2 and the side beam 201 outward by 90°. At this time, the first square hole 102 on the base 1 can be rotated to coincide with the second square hole 302 on the rotating platform 3, allowing the cargo box 2 to be lifted as a whole. Then, the fixing post 202 and the square locking block 203 at the lower corner of the cargo box 2 are inserted downward into the first square hole 102 of the base 1. When the lower end of the cargo box 2 is in contact with the upper end of the base 1, the square locking block 203 can be moved through the rotating platform 3. The second square hole 302 on the base 1 is then opened. The handle 301 is then held and rotated inward by 90° to return it to the groove 101. At this point, the second square hole 302 on the rotating platform 3 can be rotated to be perpendicular to the square locking block 203. The rotating platform 3 can then prevent the square locking block 203 from moving upward between the first square hole 102 and the second square hole 302. Then, the knob 401 is held and rotated to screw the outer stud 4 inward into the inner screw hole 103 of the base 1. At this point, the rotating platform 3 and the handle 301 can be stably locked and fixed inside the groove 101. Finally, the baffle 204 is rotated inward by 90° to fit against the side wall of the base 1, thus covering and protecting the groove 101 part of the base 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
