AI Technical Summary
The cross member of the frame assembly restricts the luggage compartment space when the trunk is lowered, resulting in limited luggage compartment space that cannot be increased by traditional means.
A forward-moving frame crossbeam structure is designed to enlarge the trunk of a bus. By improving the structure and installation method of the support, the rear crossbeam can be moved forward to provide more storage space while ensuring that the position of the fuel tank remains unchanged.
Without changing the position of the fuel tank, the rear cross member is moved forward 60mm, expanding the space of the rear storage box and improving installation stability.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bus trunks, and particularly relates to a forward-moving structure of a frame crossbeam for enlarging a bus trunk. Background Art
[0002] Since the crossbeam of the frame assembly limits the space of the luggage box when the trunk is sunken, and the space of the luggage box when the trunk is sunken is one of the important parameters of a station wagon, increasing the space of the luggage box is something that needs to be considered a lot. The original crossbeam position limits the position of the frame assembly, restricts the forward movement of the trunk when the trunk is sunk, resulting in limited space and the position of the fuel tank cannot be moved, so it needs to be adapted through a new structure.
[0003] Based on this, in order to increase the luggage compartment space, it is necessary to move the crossbeam forward, so this design proposes a frame crossbeam forward movement structure to increase the size of the bus trunk. Utility Model Content
[0004] The utility model aims to provide a vehicle frame crossbeam forward moving structure for enlarging a bus trunk.
[0005] A forward-moving frame crossbeam structure for enlarging the trunk of a passenger bus comprises: a main beam, a fuel tank, a front crossbeam, a rear crossbeam, and a support. The main beams are two in number and are installed in parallel. The main beams are installed at both ends of the front crossbeam and the rear crossbeam. The front crossbeam is parallel to the rear crossbeam. Supports are symmetrically installed on the rear crossbeam, the fuel tank is installed on the support, and a crossbar is installed at the bottom of the fuel tank.
[0006] Preferably, the support includes: a rib plate, a connecting plate, and a support plate fixing hole. The support plate structure is an "L"-shaped structure. A rib plate is fixed on the left side of the upper part of the support plate, a fixing hole is provided on the right side of the upper part of the support plate, a connecting plate is fixed on the left side of the lower part of the support plate, and an installation hole is provided at the bottom of the support plate.
[0007] Preferably, the fixing hole is installed on the rear cross beam, and the connecting plate is connected to the oil tank.
[0008] The beneficial effects of the above scheme are:
[0009] 1. The utility model shortens the support by combining the particularity of the crossbeam and ensuring that the fuel tank does not move, so that the rear crossbeam can be moved forward. During the migration process, more space is provided for the rear trunk, which greatly increases the storage space of the rear trunk. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.
[0017] according to Figure 1 and Figure 2 As shown, the utility model is a frame crossbeam forward moving structure for enlarging the trunk of a bus, comprising: a main beam 1, a fuel tank 2, a front crossbeam 3, a rear crossbeam 4, and a support 5. The main beam 1 is in two pieces and is installed in parallel. The main beam 1 is installed at both ends of the front crossbeam 3 and the rear crossbeam 4. The front crossbeam 3 is parallel to the rear crossbeam 4, wherein the rear crossbeam 4 is symmetrically installed with supports 5, the fuel tank 2 is installed on the supports 5, and a cross bar is installed at the bottom of the fuel tank 2. The installation of the supports 5 ensures that the position of the fuel tank 2 remains stationary while helping the rear crossbeam 4 to move forward.
[0018] according to Figures 3 to 5 As shown, specifically, the support 5 includes: a rib plate 51, a connecting plate 52, a support plate 53, and a fixing hole 54. The support plate 53 has an "L"-shaped structure. The rib plate 51 is fixed to the left side of the upper part of the support plate 53, and a fixing hole 54 is provided on the right side of the upper part of the support plate 53. The connecting plate 52 is fixed to the left side of the lower part of the support plate 53, and the bottom of the support plate 53 is provided with a mounting hole. The support 5 adds the rib plate 51 and the connecting plate 52 to the support plate 53 to improve the strength of the support 5. At the same time, the connecting plate 52 can also be used to install the oil tank 2, which shortens the installation distance and improves the stability of the installation.
[0019] Specifically, the fixing hole 54 is installed on the rear cross beam 4 , and the connecting plate 52 is connected to the fuel tank 2 .
[0020] During assembly, since the length of the support 5 is shortened and the support 5 is structurally improved, the rear cross beam 4 can be moved forward 60 mm. During the forward movement of the rear cross beam 4, a length of 60 mm is provided for the rear storage box, further expanding the space of the rear storage box. At the same time, the improved bracket can bring better stability to the vehicle.
