[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 6 As shown, the utility model provides an engineering vehicle body that is easy to maintain, including a vehicle body 1, a maintenance window 2 is provided on the vehicle body 1, a maintenance door 3 is provided in the maintenance window 2, the maintenance door 3 is connected to the vehicle body 1 through a suspension rocker assembly 4, and a sealing docking assembly 5 is provided between the maintenance door 3 and the inner wall of the maintenance window 2;

[0030] The suspension rocker arm assembly 4 includes a correspondingly arranged first-level rocker arm 41 and a second-level rocker arm 42. The two ends of the first-level rocker arm 41 and the second-level rocker arm 42 are respectively rotatably connected to the vehicle body 1 and the inspection door 3. The corresponding position of the first-level rocker arm 41 is rotatably connected to a gas spring device 43. The end of the gas spring device 43 away from the first-level rocker arm 41 is rotatably connected to the vehicle body 1. The inspection door 3 is fixed in two positions by applying pressure through the gas spring device 43, and the inspection door 3 can be moved under the action of the first-level rocker arm 41 and the second-level rocker arm 42, which is beneficial to the maintenance work of the maintenance personnel.

[0031] Specifically, the sealing docking assembly 5 includes a corresponding first-level baffle 51 and a second-level baffle 52. The first-level baffle 51 and the second-level baffle 52 are respectively arranged on the inspection door 3 and the inner wall of the inspection window 2. The first-level baffle 51 and the second-level baffle 52 are respectively connected to the first-level magnet bar 53 and the second-level magnet bar 54 on the opposite sides.

[0032] Furthermore, a first-level buffer pad 55 and a second-level buffer pad 56 are respectively connected to the opposite sides of the first-level magnet bar 53 and the second-level magnet bar 54. The structures of the first-level buffer pad 55 and the second-level buffer pad 56 match each other, which can improve the sealing and connection strength between the inspection door 3 and the inner wall of the inspection window 2, prevent external water from entering through the gap position of the inspection door 3 to protect internal equipment, and prevent collision and wear between the inspection door 3 and the vehicle body 1.

[0033] Furthermore, the lower ends of the primary rocker arm 41 and the secondary rocker arm 42 are respectively connected to the primary rotating shaft 6 and the secondary rotating shaft 7, and the primary rotating shaft 6 and the secondary rotating shaft 7 are both fixed on the inspection door 3.

[0034] It is worth noting that the upper ends of the primary rocker arm 41 and the secondary rocker arm 42 are respectively connected to the primary bearing 8 and the secondary bearing 9, and the primary bearing 8 and the secondary bearing 9 are respectively connected to the primary fixing seat 10 and the secondary fixing seat 11, and the primary fixing seat 10 and the secondary fixing seat 11 are both fixed on the vehicle body 1.

[0035] It is worth noting that one end of the gas spring device 43 is connected to the first-stage rocker arm 41 through the third-stage bearing 12 , and the other end is connected to the vehicle body 1 through the third-stage rotating shaft 13 .

[0036] It is worth mentioning that a handle 14 is fixedly connected to the side of the inspection door 3 away from the vehicle body 1. A protective cover is provided on the handle 14.

[0037] The gas spring device 43 is a prior art and will not be described in detail.

[0038] Working principle and process: The maintenance personnel hold the handle 14 and pull it outward. At this time, the first-level rocker arm 41 and the second-level rocker arm 42 rotate around the first-level bearing 8 and the second-level bearing 9. Under the action of the first-level rocker arm 41 and the second-level rocker arm 42, the maintenance door 3 moves outward a certain distance and then moves upward, forming an arc-shaped motion trajectory as a whole. At this time, the maintenance door 3 is located at the upper position outside the maintenance window 2 to completely expose the maintenance window 2, and the maintenance door 3 is fixed under the pushing force of the gas spring device 43. After maintenance, the operation can be reversed to make the maintenance door 3 located in the maintenance window 2. At this time, the sealing docking assembly 5 is structurally matched, which can improve the sealing and connection strength between the maintenance door 3 and the inner wall of the maintenance window 2, and prevent external water from entering through the gap position of the maintenance door 3 to protect internal equipment, and prevent collision and wear between the maintenance door 3 and the vehicle body 1.
