Description

Technical Field

[0001] The utility model relates to the technical field of bus outer shells, in particular to a streamlined and lightweight bus outer shell. Background Art

[0002] The bus shell mainly plays a supporting and protective role for the whole bus, making its structure lighter and stronger, which is beneficial to driving economy and protection effect.

[0003] After searching, I found prior art (publication number: CN118790352A), which describes a "body structure and bus," including an underframe, hanging beams, and a body frame. The underframe includes a keel frame and crossbeams. A battery rack is located in the center of the keel frame, with multiple protective beams staggered on either side. The battery rack is equipped with multiple placement plates for battery packs. A fixed shaft and a rotating shaft are vertically disposed at the other end of the hanging beam. The battery rack has a raised portion on the side for mounting the fixed and rotating shafts. The raised portion has a cutting edge on the edge of the shaft hole at the fixed shaft. When the side of the bus encounters a large impact force, the brittle fixed shaft can be easily severed by the cutting edge, allowing the protective beam to rotate about the rotating shaft and the hinge shaft, creating a swinging force-relieving effect. This provides a buffering force-relieving effect at the battery rack, preventing deformation of the frame and squeezing of the batteries, thereby providing protection."

[0004] Although the bus shell in the existing technology can achieve the effects of protection and easy partial disassembly, it still has some shortcomings: the existing bus shell generally has only one layer of anti-collision beam structure, and the overall width of the front of the bus is relatively small compared to the body, which has a long-distance energy absorption effect, resulting in a deviation in the protection effect when encountering a larger impact. Secondly, the buses involved generally use air conditioning to cool the interior, but when the external temperature is not very hot, turning on the air conditioning at this time will lose some power, and the windows cannot be opened for ventilation when driving on the highway. Utility Model Content

[0005] In order to overcome the defects of the existing technology, a streamlined lightweight bus shell is provided to solve the problems that the existing bus shell has a deviation in protection effect and cannot achieve natural wind heat dissipation on highways.

[0006] To achieve the above-mentioned purpose, a streamlined lightweight passenger car shell is provided, comprising: a frame body, the frame body including a front air guide frame, and the rear side of the air guide frame is connected to the roof, and the inner top wall of the roof is provided with an inner air outlet, the front side of the frame body is provided with an upper anti-collision beam, and the upper anti-collision beam is located on the lower side of the air guide frame, and the lower side of the upper anti-collision beam is provided with a lower anti-collision beam, the rear side of the lower anti-collision beam is connected to a side panel, and the lower end of the side panel is provided with a wheel hub groove, and a structural beam is connected between the side panel and the roof.

[0007] Furthermore, the guide frame is configured as a V-shaped structure, and the guide frame includes an upper guide plate on the upper side and a lower guide plate connected to the lower side, and the connection ends of the upper guide plate and the lower guide plate face outward.

[0008] Furthermore, the upper anti-collision beam includes two upper and lower arc-shaped cross beams, and a reinforcing rod connected between the cross beams, and vertical beams are connected to the left and right ends of the cross beam.

[0009] Furthermore, the lower anti-collision beam includes a hollow cross beam at the front end, and the upper ends of the hollow cross beam are connected to diagonal rods, and the rear end of the hollow cross beam is connected to a diagonal support rod, while the upper end of the diagonal rod is connected to the bottom of the upper anti-collision beam.

[0010] Furthermore, an air inlet is provided at the front end of the roof, an inner cavity is provided behind the air inlet and inside the roof, and an inner air outlet is provided at the bottom of the inner cavity.

[0011] Furthermore, a diamond mesh plate is provided on the rear side of the air inlet, an activated carbon mesh plate is provided on the rear side of the diamond mesh plate, and a sponge filter element is connected to the rear end of the activated carbon mesh plate.

[0012] Furthermore, the structural beams are arranged at equal intervals along the length direction of the frame body, and the upper and lower ends of the structural beams are respectively connected to the roof and the side panels by welding.

[0013] The beneficial effects of the present invention are:

[0014] 1. The anti-collision structure formed by the upper and lower anti-collision beams increases the anti-collision area of ​​the front end of the frame body. At the same time, the hollow crossbeam, diagonal rods and diagonal braces included in the lower anti-collision beam enhance the energy absorption and buffering effect of the structure, thereby enhancing the overall protection effect;

[0015] 2. The upper and lower deflectors included in the deflector frame can be used to divert the airflow hitting the front of the vehicle horizontally and vertically when driving at high speed, thereby reducing the wind resistance of the bus shell. At the same time, part of the air diverted upward can enter the inner cavity of the roof through the air inlet;

[0016] 3. By utilizing the air inlet and inner cavity at the front end of the roof, when driving at high speed and the windows cannot be opened, the external air flow can be introduced into the interior of the roof. During the process, the air is filtered through the diamond mesh plate, activated carbon plate and sponge filter element, and then output into the cabin through the internal air outlet, thereby accelerating the air flow inside the cabin and achieving cooling without turning on the air conditioner, thereby reducing the power loss of the bus and improving fuel economy.
