Description

Technical Field

[0001] The utility model relates to the field of tricycle frame structures, and particularly to a tricycle frame with a headstock and a carrying pole. Background Art

[0002] When a tricycle is running, due to the whole vehicle colliding or running for a long time, the frame is prone to be damaged, the safety factor is low, and the structural stability is poor. At present, most tricycle frames adopt a common structure, including a bumper and two auxiliary beam pipes. Such a frame structure has poor stability. When the tricycle is running and collides at the headstock or runs for a long time, the headstock structure is prone to be damaged, resulting in casualties. Therefore, it is necessary to provide a frame with stable structure and certain impact resistance. Content of the Utility Model

[0003] The utility model aims to provide a tricycle frame with a headstock and a carrying pole to provide a frame with stable structure and certain impact resistance.

[0004] To achieve the above object, the utility model adopts the following technical scheme: The utility model aims to provide a tricycle frame with a headstock and a carrying pole to provide a frame with stable structure and certain impact resistance.

The driving frame includes a main beam pipe. A headstock pipe is welded to the top of the main beam pipe. A baffle structure is welded to the front of the main beam pipe. The baffle structure is in a shape of a Chinese character 'tian'. Arc-shaped pipes are arranged on both sides of the baffle structure. A carrying pole is arranged between the two arc-shaped pipes for connection. The middle of the carrying pole is connected to the headstock pipe through a connecting pipe.

[0006] The beneficial effects of this scheme are as follows: In this technical scheme, a baffle structure is welded to the front of the main beam pipe. The baffle structure is in a shape of a Chinese character 'tian'. The baffle structure in the shape of a Chinese character 'tian' has high structural strength and can withstand a certain impact force without deformation. Arc-shaped pipes are arranged on both sides of the baffle structure, which plays a role in strengthening the overall stability of the baffle structure. At the same time, a carrying pole is arranged between the two arc-shaped pipes for connection. The carrying pole structure connects the two arc-shaped pipes and plays a supporting role for them. When the vehicle collides, it can effectively reduce the impact force of the vehicle body tipping over, prevent or reduce the harm caused by the tricycle body tipping over to the driver. At the same time, the structure is simple, the manufacturing cost is low and the installation is convenient. In addition, the middle of the carrying pole is connected to the headstock pipe through a connecting pipe, which further strengthens the structural stability of the driving frame and fixes the position of the headstock pipe, preventing the headstock pipe from shifting or breaking during impact, resulting in operation problems caused by the disconnection of internal pipelines.

[0007] Preferably, as an improvement, the included angle between the headstock pipe and the vertical line of the ground is 20±2°.

[0008] The beneficial effects are: this angle design helps to disperse the force from the front direction of the vehicle, so that during the steering process, the force distribution of the front of the vehicle is more even, thereby improving the stability of the vehicle during driving; by adjusting the head tube and angle, it is convenient to install the steering wheel and the steering wheel control line later, which can effectively improve the vehicle's handling performance, allowing the driver to control the vehicle more accurately and flexibly during driving, making the overall frame structure more compact and reasonable, and facilitating the integration of more functional components in a limited space.

[0010] The beneficial effects are as follows: by welding the reinforcing plate, on the one hand, the connection strength between the arc tube and the retaining tube structure can be increased, and at the same time, the reinforcing plate can play a role in wind protection. The aluminum alloy reinforcing plate can support and protect the retaining tube structure and the arc tube structure in the event of a collision, and the reinforcing plate can prevent splashing objects from splashing onto the driver. The reinforcing plate surface is stamped with reinforcing grooves, which can increase the structural strength of the reinforcing plate on the one hand, and guide the wind when driving on the other hand.

[0012] The beneficial effects are as follows: the connection method of the main load-bearing beam of the car body is adjusted from being fixed to the cab to being fixed in the cab, which can increase the connection strength between the car body and the cab and avoid the wear of the connection and possible rust in the later stage caused by the traditional method. Now the connection is transferred to the inside of the cab, and the first longitudinal beam and the second longitudinal beam are at the junction of the head and the car body, which is not easy to be damaged. Therefore, the connection strength between the frame and the cab can be increased. At the same time, even when carrying more heavy objects, it is not easy to be damaged in turning and the like. On the other hand, the first longitudinal beam and the second longitudinal beam are fixed to the middle part of the cab tray by supporting beams, and the car seat cushions and the like can be placed on the first longitudinal beam and the second longitudinal beam. The above connection method can increase the integrity of the car body.

[0014] The beneficial effects are: the first longitudinal beam and the second longitudinal beam are supported by the support rod, so that the load-bearing capacity of the frame is improved, and the connection strength between the frame and the cab is improved.

[0015] Preferably, as an improvement, the arc tubes are all U-shaped, and both ends of the arc tubes are welded to the retaining tube structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The embodiment is basically as follows Figure 1-Figure 3 As shown, Figure 1 and Figure 2 The front of the vehicle is shown as a flat frame, including a driving frame and a load bracket fixedly connected, the driving frame includes a main beam tube 1, a head tube 3 is welded on the top of the main beam tube 1, and a pipe blocking structure 2 is welded on the front of the main beam tube 1. Figure 3The shown baffle tube structure 2 is in a cross shape. Arc-shaped tubes 4 are provided on both sides of the baffle tube structure 2. The arc-shaped tubes 4 are both U-shaped. Both ends of the arc-shaped tubes 4 are welded to the baffle tube structure 2. A crossbar 5 is provided between the two arc-shaped tubes 4 for connection. The middle of the crossbar 5 is connected to the head tube 3 through a connecting tube 6.

At the same time, a crossbar 5 is provided between the two arc-shaped tubes 4 for connection. The crossbar 5 structurally connects the two arc-shaped tubes 4 and supports them. When the vehicle collides, it can effectively reduce the impact force of the vehicle body tipping. The angle between the head tube 3 and the vertical line of the ground is 20±2°. This angle helps to disperse the force from the head direction through experiments, making the force distribution on the head more uniform during the turning process, thereby improving the stability of the vehicle during driving. A reinforcing plate 7 is welded between the arc-shaped tube 4 and the baffle tube structure 2. The reinforcing plate 7 is made of aluminum alloy, and reinforcing grooves 8 are stamped on the surface of the reinforcing plate 7. By welding the reinforcing plate 7, on the one hand, the connection strength between the arc-shaped tube 4 and the baffle tube structure 2 can be increased, and at the same time, the reinforcing plate 7 can play a role in wind protection.
