Description

Technical Field

[0001] The utility model relates to the technical field of railways, in particular to an integrated door frame waterproof undercarriage box. Background Art

[0002] With the continuous growth of my country's urban population, the number of private vehicles has increased, bringing a series of problems to urban traffic, increased environmental pollution, and energy crises. With the emergence of subways, their convenient and fast operation mode has been favored by more and more cities.

[0003] With the continuous development of subway trains, the requirements for train quality are becoming increasingly higher. For traditional undercarriage electrical boxes, sealing, interchangeability, and maintainability are extremely important. As a result, research on subway undercarriage boxes has increased. The current challenge is how to design an undercarriage electrical box that is simple to manufacture and has a good sealing structure. The core of this technology is to study how to simplify the structure of the undercarriage electrical box while improving its sealing effect.

[0004] In subway trains, most of the components inside the box are installed at the bottom of the box, which means that impurities such as water vapor and debris may damage the components inside the box if the box is not well sealed. Especially in scenarios with heavy rainfall, it is very likely to cause leakage and seepage in the box. Moreover, for some undercar boxes that are limited in height due to space issues but still need to install pipe joints, the use of an integrated door frame is more flexible and can avoid the installation of pipe joints to meet the required standards. Currently in the relevant technology, the sealing structure between the box and the box cover is relatively simple, and the solution is single. It is easy for water vapor and impurities to enter the interior of the box, causing component failure and vehicle operation failure. Secondly, the use of existing undercar box door frames is not applicable to the installation of all undercar boxes, which increases the difficulty of operation during installation and complicates the process.

[0005] The existing technology suffers from a relatively simple sealing structure between the box and lid, resulting in inadequate waterproofing and sealing. During train operation, if there is heavy rainfall, the box is very likely to leak water, potentially affecting components and wiring within, leading to operational malfunctions. Even though some boxes have limited height due to space constraints, fittings are still required to thread the wiring harness through the box, making the process more difficult, time-consuming, and labor-intensive.

[0006] For this reason, we urgently need to provide a kind of integrated door frame waterproof vehicle lower box. Utility Model Content

[0007] The purpose of the utility model is to provide an integrated door frame waterproof vehicle lower box to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: an integrated door frame waterproof undercarriage box, comprising a body plate and a cover plate, wherein the cover plate is arranged at the bottom end of the body plate, and a sealing mechanism and a reinforcement mechanism are arranged at the top end of the body plate.

[0009] The sealing mechanism includes an integrated door frame, a fixed plate, a folding part one, a folding part two, a folding part three and a fixing bolt. The integrated door frame is installed on the top of the body plate. The fixed plate, the folding part one, the folding part two, and the folding part three are arranged above the integrated door frame. The fixing bolt is connected to the inside of the fixed plate.

[0010] Preferably, the reinforcement mechanism includes a fixing frame, a connecting bolt, a rotating rod, a rotating handle and a reinforcement plate, the fixing frame is arranged on the side of the body plate, the connecting bolt is connected to the fixed end of the fixing frame, the rotating rod is connected to the inside of the top of the fixing frame, the rotating handle is installed at the top of the rotating rod, and the reinforcement plate is connected to the bottom end of the rotating rod.

[0011] Preferably, the integrated door frame is made of stainless steel by bending the stainless steel material multiple times, so that the door frame is integrated, thereby improving the sealing performance of the device, and the integrated door frame is welded to the top of the body plate by a welding device, so that the integrated door frame is installed more firmly.

[0012] Preferably, the cover plate is fixed to the bottom end of the body plate by screws, thereby facilitating installation and fixation of the cover plate and also facilitating replacement of the cover plate. The fixing bolt is connected to the internal thread of the fixing plate, thereby improving the sealing stability of the device.

[0013] Preferably, the reinforcement mechanism is symmetrically distributed on both sides of the integrated door frame, thereby improving the reinforcement performance of the device. The fixing frame is fixed to the side of the body plate by a connecting bolt, which makes it easy to install and disassemble the fixing frame at any time and has a certain convenience.

[0014] Preferably, the outer wall of the rotating rod is connected to the internal thread of the top of the fixing frame. Through the rotation of the rotating rod, the reinforcement plate further reinforces the integrated door frame. The connecting end of the reinforcement plate is hinged to the bottom end of the rotating rod to prevent the rotation of the rotating rod from driving the reinforcement plate to rotate, thereby improving the reinforcement efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This integrated doorframe waterproof undercarriage box utilizes a sealing mechanism and a post-weld gluing method to effectively enhance the box's waterproof seal, thereby reducing risks and ensuring train safety. Furthermore, the use of sealing strips on the box body not only enhances the box's sealing effectiveness but also provides a certain degree of cushioning, preventing deformation caused by excessive jolting during train operation. This addresses the issues raised in the background art.

[0017] 2. The integrated door frame is waterproof undercarriage. The integrated frame in the device is simple to manufacture, which can effectively reduce the use cost and the difficulty of manufacture. It provides a better option for undercarriages with limited box height due to insufficient space. The integrated frame adds notches to effectively avoid pipe joints. The use of sealing strips increases the sealing of the box and prevents deformation caused by collision between the box and the cover due to bumps in the vehicle. In addition, by setting a reinforcement mechanism, the integrated door frame is installed more firmly. BRIEF DESCRIPTION OF THE DRAWINGS
