Main cabin door; 2. Positioning frame plate; 3. Operating door; 4. Electromagnetic lock switch assembly; 5. Sealing stop; 6. Support plate; 41. Magnet part; 42. Main unit. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Example: Reference Figure 1This embodiment provides a city bus door structure; it includes a main door 1 installed on the bus; a battery installed inside the main door 1; a window is opened on the main door 1 at a position opposite to the battery switch; a ring-shaped positioning frame plate 2 is installed at the main window; an openable and closable operating door 3 is hinged to the middle of the positioning frame plate 2; when the operating door 3 is opened, the operator can operate the battery through the auxiliary window; a pair of cooperating electromagnetic lock switch assemblies 4 are installed inside the positioning frame plate 2 and the operating door 3; the electromagnetic lock switch assemblies 4 are connected to the vehicle's electrical system via cables, and their operation is controlled by the electrical system; sealing stops 5 are provided between the positioning frame plate 2 and the main door 1, and between the operating door 3 and the positioning frame plate 2.

[0019] The sealing stop 5 is made of high-temperature resistant and aging-resistant silicone material; the sealing stop has an embedded waterproof groove to further enhance waterproof performance. The choice of silicone material ensures that the seal maintains good elasticity and sealing performance under extreme high and low temperature environments that buses may encounter, as well as under long-term outdoor exposure conditions, avoiding the risk of leakage due to material aging. The embedded waterproof groove design can form multiple barrier layers when the sealing surfaces are in contact, significantly improving the effect of preventing splashing and capillary seepage.

[0020] Support plates 6 are installed on the inner sides of both the positioning frame plate 2 and the operating door 3. The support plate 6 is a cantilevered flat plate component with positioning holes. The electromagnetic lock switch assembly 4 is installed on the corresponding support plate 6 at the positioning holes using bolt assemblies. The cantilevered support plate design provides sufficient rigidity and installation space, and the positioning holes ensure the accuracy and consistency of the installation position of the electromagnetic lock switch assembly. The bolt assembly connection method allows for fine-tuning when necessary to optimize the alignment and sensitivity of the electromagnetic lock switch assembly.

[0021] The positioning frame 2 is embedded in the window of the main cabin door 1. The embedded installation method allows the positioning frame to form a smooth transition with the outer surface of the main cabin door, improving the overall appearance.

[0022] The electromagnetic lock switch assembly 4 includes a magnet part 41 and a main unit part 42. The magnet part 41 is mounted on the operating door 3; the main unit part 42 is mounted on the positioning frame plate 2; the main unit part 42 is connected to the housing of the vehicle's electrical system via a wiring harness. The housing used in the electromagnetic lock switch assembly is an Amp.282104-1 type housing; the electromagnetic lock switch assembly in this embodiment is a GS-M type miniature electromagnetic lock switch manufactured by Keyence. The non-contact triggering method provided by the electromagnetic lock switch assembly completely eliminates the risks of wear, poor contact, or accidental activation caused by repeated pressing of traditional mechanical switches, greatly improving the reliability and lifespan of the system.

[0023] The vehicle's electrical system includes a display located on the driver's dashboard; the display shows the operating status of the electromagnetic lock switch assembly 4; and a remote switch for controlling the operation of the electromagnetic lock switch assembly 4.

[0024] In the actual installation of the utility model device in this embodiment, it is only necessary to first fix the main cabin door to the side frame of the city bus; then, hinge the operating door to the positioning frame plate accordingly, and then embed the assembled positioning frame plate into the window position of the main cabin door, ensuring that its connection with the main cabin door is tight; then, install sealing stops on the positioning frame plate and the edge of the operating door, and test its waterproof performance; finally, install the electromagnetic lock switch assembly accordingly through the bracket, and connect its main unit to the electrical system of the whole vehicle through the wiring harness and sheath.

[0025] When the operating door needs to be opened, the driver or maintenance personnel can control the electromagnetic lock switch assembly to open it via a remote switch on the electrical system, without direct contact.

[0026] The on / off status of the electromagnetic lock switch assembly can be viewed in real time on the in-vehicle display screen.

[0027] After the small door is closed, the sealing stop automatically closes, ensuring that the external environment does not affect the vehicle's internal systems.

[0028] This invention is applicable to all types of urban buses, especially new energy electric buses. By introducing a bracket and a small sealed door, it not only improves the vehicle's safety and intelligence but also simplifies daily maintenance procedures. In the future, this design can be further extended to other types of commercial vehicles, showing broad application prospects.
