Description

Technical Field

[0001] This utility model relates to the field of vehicle frame reinforcement technology, and in particular to a protective reinforcement structure for a semi-trailer vehicle frame. Background Technology

[0002] A semi-trailer is a trailer with its axle positioned behind the vehicle's center of gravity and equipped with a coupling device that transmits horizontal and vertical forces to the tractor. Uneven stress on the semi-trailer frame is one of the main causes of frame deformation, torsion, and fatigue fracture. During operation, the weight and distribution of the cargo carried by the semi-trailer will change, resulting in uneven load distribution on the frame and generating additional bending and torque moments. Therefore, the frame needs to be reinforced with protective and strengthening structures.

[0003] Chinese Patent Publication No. CN214607408U discloses a semi-trailer frame reinforcement structure, including a main body with a connecting plate fixedly connected to the front side of the main body. This invention utilizes a combination of a connecting plate, a fixing plate, a support plate, a fixing block, a slot, a square through hole, a storage groove, a through hole, and a fixing device. When the through hole at the top of the fixing block aligns with the slot at the bottom of the main body, rotating the rotating rod causes the limiting plate to align with the square through hole. Releasing the rotating rod causes the tension spring to elastically deform, pulling the pull plate back to its original position. The pull plate then moves, causing the locking rod to pass through the through hole into the slot, thus reinforcing the connection between the main body and the fixing plate. This solves the problem that existing semi-trailer frames lack reinforcement devices for the rear protective plate, making it easy for rear-end collisions on highways to break the protective plate down to the bottom of the semi-trailer frame. This semi-trailer frame reinforcement structure offers the advantages of strengthening and reinforcing, and is worthy of promotion.

[0004] When using a traditional semi-trailer frame protection reinforcement structure, if the bottom of the frame cannot form an angular support, it will affect the support strength of the protection reinforcement structure, which may lead to deformation of the protection reinforcement structure. In addition, since the outer side of the protection reinforcement structure lacks a fastening structure, its bracket may come loose. Utility Model Content

[0005] The main purpose of this utility model is to provide a protective reinforcement structure for a semi-trailer frame, which can effectively solve the problem that if the bottom of the frame cannot form an angular support member, the support strength of the protective reinforcement structure will be affected, which may lead to deformation of the protective reinforcement structure. In addition, since the outer side of the protective reinforcement structure lacks a fastening structure, its bracket may detach.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] As a further embodiment of this utility model, the stable support structure includes a positioning head, a fixing foot, a bearing joint, a fixing frame, and a diagonal rod. The positioning head is fixed at the bottom center of the support beam, the fixing foot is fixed at the top of the reinforcing beam, the bearing joint is snapped onto the outer surface of the positioning head, the fixing frame is fixed at the bottom of the bearing joint, and the diagonal rod is fixed between the bearing joint and the fixing foot.

[0009] As a further embodiment of this utility model, the bottom of the fixing frame is flush with the top of the reinforcing beam, and the positioning head, fixing foot, bearing joint, fixing frame and diagonal bar are combined to form an angled support.

[0010] As a further embodiment of this utility model, a first fixing pin is connected between the receiving joint and the positioning head, and a second fixing pin is connected between the inclined rod and the fixing foot. The receiving joint is fixedly connected to the positioning head through the first fixing pin, and the inclined rod is fixedly connected to the fixing foot through the second fixing pin.

[0011] As a further embodiment of this utility model, a fixing plate is fixedly connected to the outer surface of the column, and a fastening frame is provided in the outer groove of both the first bracket and the second bracket, and the fastening frame is arranged parallel to the fixing plate.

[0012] As a further embodiment of this utility model, a fastening rod is fixedly connected to the outer surface of the fastening frame. The fastening rod passes through the interior of the column and the fixing plate, and a locking head is connected between the fastening rod and the fixing plate.

[0013] The beneficial effects of this utility model are as follows: by setting a stable support structure, an angular support member can be formed at the bottom of the semi-trailer frame, which can improve the support strength of the protective reinforcement structure and prevent the protective reinforcement structure from deforming.

[0014] By setting up a fixing plate, a fastening frame, and a fastening rod, the structure can be fastened to the outside, preventing the support of the protective reinforcement structure from coming loose. Attached Figure Description
