[0025] This invention primarily addresses the problem of existing door hinge boxes that only cover and decorate the door pump, leaving the door hinge and its fasteners exposed, resulting in poor aesthetics. The basic inventive concept of this invention is: the back of the door hinge box body is designed as an open structure, and a clearance portion for the door hinge's swing arm assembly and a door hinge clearance groove for the door hinge to pass laterally are designed on the door hinge box body. This allows the door hinge box body to be fastened to the outside of the door hinge and door pump, completely covering and decorating the door pump and door hinge except for the parts that must be exposed, thereby greatly improving aesthetics while providing both coverage and protection for the door pump and door hinge.

[0026] Based on the above inventive concept, the features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0027] Embodiments of the door hinge box of this utility model:

[0028] like Figure 1-2As shown, the door hinge box includes a door hinge box body with an open back. The inner cavity of the door hinge box body is used to accommodate the door hinge and door pump. The door hinge box body has a segmented structure, including an upper box body 1, a middle box body 2, a lower box body 3, and connecting sections between adjacent box bodies. There is a clearance part 4 between the upper box body 1 and the middle box body 2 to avoid the upper swing arm assembly on the door hinge. There is a clearance part 4 between the middle box body 2 and the lower box body 3 to avoid the lower swing arm assembly on the door hinge. Door hinge clearance grooves 5 with their openings facing the back are respectively provided on the bottom plate of the upper box body 1, the top plate and bottom plate of the middle box body 2, and the top plate of the lower box body 3. The door hinge clearance grooves 5 are U-shaped grooves with a rounded bottom surface. The groove width is slightly larger than the diameter of the door hinge to ensure that the door hinge can pass laterally. The door hinge box body is made of ABS vacuum forming, which makes it lightweight and forms a three-section integrated door hinge box in one piece.

[0029] The door hinge box body is provided with a mounting structure for fixing the door hinge box to a mounting surface inside the vehicle. Specifically, such as... Figure 2 As shown, a mushroom-shaped latch 6 is fixedly connected to the back of the hinge box body, securing the hinge box to the mounting surface. The mushroom-shaped latch 6 can be adhesively attached to the hinge box body. The hinge box is secured to the mounting surface via the mushroom-shaped latch 6, which has a simple structure, reliable connection, and is not prone to loosening and causing abnormal noise. Furthermore, if the hinge box is damaged, the mushroom-shaped latch 6 can be easily opened to replace it with a new hinge box, making the installation and removal of the hinge box very convenient.

[0030] The mushroom-shaped latches 6 are arranged in two rows on the left and right side panels of the door hinge box body, respectively. Each row includes three mushroom-shaped latches 6, which are arranged vertically at intervals within the same row. The three mushroom-shaped latches 6 in the same row are fixedly connected to the side panels of the upper section box 1, the middle section box 2, and the lower section box 3, respectively. The mushroom-shaped latches 6 on the left and right side panels of the same section box are arranged facing each other. This arrangement of the mushroom-shaped latches 6 provides multi-point fixation for the door hinge box, ensuring the reliability of the door hinge box's fixation on the vehicle's interior mounting surface.

[0031] The adjacent panels of the door hinge box are all rounded. Since the door hinge box is next to the step, and passengers step on the step when getting on and off the vehicle, the door hinge box is right next to the passengers' feet. If the door hinge box has sharp corners, it is easy to scratch passengers. Designing the adjacent panels of the door hinge box to have rounded transitions can prevent sharp corners from scratching passengers, thus improving safety, and also improve the overall aesthetics.

[0032] During installation, pre-fix the mushroom-shaped hook-and-loop fasteners 6 on the corresponding mounting surface inside the vehicle. Attach the door hinge box to the outside of the door hinge and door pump, securing the door hinge box to the mounting surface using the mushroom-shaped hook-and-loop fasteners 6. The two clearance parts 4 of the door hinge box allow space for the upper and lower swing arm assemblies on the door hinge to move. The door hinge passes laterally through the opening of the door hinge clearance groove 5 and enters the door hinge clearance groove 5. The door hinge clearance groove 5 is fastened to the outside of the door hinge. Except for the parts that must be exposed, the door pump and other parts of the door hinge are fully covered and decorated, greatly improving the aesthetics while providing protection for both the door pump and the door hinge.

[0033] Of course, this utility model is not limited to the embodiments described above.

[0034] For example, in the above embodiment, a mushroom-shaped fastener is fixedly connected to the back of the door hinge box body, and the door hinge box is fixedly installed to the vehicle interior mounting surface via the mushroom-shaped fastener. In other embodiments, a snap-fit ​​can be provided on the door hinge box body, and a corresponding slot can be provided on the vehicle interior mounting surface, and the door hinge box can be fixedly installed to the vehicle interior mounting surface via the snap-fit. In other embodiments, a dedicated mounting structure may not be provided on the door hinge box, and the door hinge box can be glued and fixed to the vehicle interior mounting surface during installation.

[0035] For example, the above embodiments only provide one arrangement of the mushroom-shaped hooks. In actual applications, the arrangement of the mushroom-shaped hooks can be flexible and varied. The mushroom-shaped hooks can be arranged in one row, two rows, three rows, or more rows. For example, when the mushroom-shaped hooks are arranged in one row, they can be placed in the middle of the width direction of the hinge box body, and mushroom-shaped hooks can be set on the top and bottom plates of each section of the box body. When the mushroom-shaped hooks are arranged in three rows, one row of mushroom-shaped hooks can be set on the left and right side plates of the hinge box body, and another row of mushroom-shaped hooks can be set in the middle of the width direction of the hinge box body. The number of mushroom-shaped hooks in each row can also be changed, and can be one, two, three, or more. In addition to setting mushroom-shaped hooks on the left and right side plates of the hinge box body, mushroom-shaped hooks can also be set on the top and bottom plates of the hinge box body, as long as it can ensure that the hinge box is securely fixed to the mounting surface. In other embodiments, the mushroom-shaped fasteners on each section of the box can be staggered in the vertical direction, instead of being required to be directly aligned horizontally; when the door hinge box body is divided into multiple sections, mushroom-shaped fasteners can be provided on some sections, instead of being required to be provided on every section, as long as the reliability of the door hinge box can be guaranteed.

[0036] For example, in the above embodiment, the adjacent panels of the door hinge box body have a rounded transition. Of course, in other embodiments, the adjacent panels of the door hinge box body can also have a right-angle transition. In this case, corner protectors can be attached at the right-angle positions to prevent passengers from being scratched.

[0037] This utility model also provides an embodiment of a passenger vehicle.

[0038] The bus includes a passenger door, which includes a door panel, a door hinge, and a door pump. The door pump is connected to the door hinge to drive the door hinge to rotate.
