Description

Technical Field

[0001] This utility model relates to a seat bucket, specifically a quick-release seat mechanism suitable for tricycles. Background Technology

[0002] Currently, most three-wheeled motorcycle buses use a rear-mounted engine structure to reduce noise and vibration and improve passenger comfort. While this has certain advantages in layout and performance, it does have drawbacks in terms of maintenance convenience. This is usually addressed by adding a rear access door. Although this structure provides some convenience for engine inspection and maintenance, the limited space in the engine compartment, the complexity of transmission system maintenance, and the difficulty of maintaining the lubrication and cooling systems make this rear-opening layout extremely inconvenient. Furthermore, with the engine rear-mounted and the front of the vehicle obstructed by the seat bucket and other front-mounted mechanisms, the engine's heat can only accumulate under the seat bucket, slowly dissipating during driving. Prolonged exposure to this environment can easily lead to engine overheating and shutdown.

[0003] Currently, a utility model patent with publication number CN203094291U discloses a fuel tank assembly structure for a hybrid electric tricycle, including a range extender, a seat bucket, and a fuel tank. The range extender is fixed to the frame below the seat bucket by a range extender mounting bracket. One bottom side of the seat bucket has a through hole. The fuel tank is located on one side of the through hole in the seat bucket, with its lower end passing through the through hole and fixed to the frame by a fuel tank bracket. The fuel tank is positioned above the range extender's power unit. The lower end of the seat bucket is connected to the front upper tube of the frame via a seat bucket hinge, forming a structure that can be flipped open to expose the fuel tank. A seat bucket cover is rotatably connected to the top of the seat bucket. This utility model has advantages such as a simple and compact structure, reasonable layout, and ease of range extender maintenance.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN203094291U connects the lower end of the seat bucket to the front top tube of the frame via a seat bucket hinge, forming a structure that can be flipped open to expose the fuel tank, thereby providing a window for maintenance. However, this patent can only open the seat bucket part, which means that during maintenance, the staff can only access the window in the area directly below the seat bucket. In actual maintenance, the window space is relatively small, making operation inconvenient. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a quick-release seat mechanism suitable for tricycles, which can provide a relatively large inspection window to reduce the difficulty of maintenance and can effectively guide airflow through the engine to improve heat dissipation efficiency.

[0006] To achieve the above objectives, this utility model is applicable to a quick-release seat mechanism for tricycles, including a seat cushion, a fixing hook, a guide cone hole, a fixing tail plate, a rear limiting plate for the upper seat bucket, a reinforcing plate, a lower seat bucket, a frame, a buckle, and a deflector. The lower seat bucket is fixedly installed on the pedal of the frame. A maintenance upper seat bucket that can be flipped forward is installed at the front of the lower seat bucket via a pivot. The maintenance upper seat bucket and the lower seat bucket are locked by a buckle. The joint between the maintenance upper seat bucket and the lower seat bucket is lower at the front and higher at the back. A fixing hook hole is opened at the front of the upper surface of the maintenance upper seat bucket. A guide cone is fixedly installed at the rear of the upper surface of the maintenance upper seat bucket. The fixing hook at the bottom of the seat cushion is inserted into the fixing hook hole. The guide cone is fitted into the guide cone hole at the bottom of the seat cushion. A spring pin on the fixing tail plate at the rear of the seat cushion is inserted into the pin hole at the rear of the maintenance upper seat bucket.

[0007] In addition, the quick-release seat mechanism for tricycles proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, a guide plate is provided at the front of the lower seat bucket.

[0009] As a further improvement of this utility model, a reinforcing plate is fixedly installed on the inner side of the inspection upper seat bucket directly below the seat cushion.

[0010] As a further improvement of this utility model, the upper seat bucket rear limiting plate is fixedly installed at the rear of the upper seat bucket. When the upper and lower seat buckets are closed, the upper seat bucket rear limiting plate is stuck on the outside of the lower seat bucket.

[0011] As a further improvement of this utility model, a heat dissipation window is provided at the rear of the lower seat bucket.

[0012] As a further improvement of this utility model, the upper edge of the lower seat barrel is provided with a groove corresponding to the maintenance of the lower edge of the upper seat barrel.

[0013] By employing the above-described solution, this utility model possesses at least the following advantages: By separating the traditional seat bucket into an upper and lower inspection seat bucket, and ensuring the seam between the upper and lower inspection seat buckets is lower at the front and higher at the back, a larger engine inspection window can be exposed when the upper inspection seat bucket is folded forward, reducing the difficulty of maintenance. Simultaneously, the deflector located at the front of the lower seat bucket redirects the airflow under the vehicle while it is in motion, directing it directly at the engine, effectively improving the engine's operating environment and enhancing heat dissipation efficiency. Furthermore, the easily removable seat cushion significantly reduces the difficulty of replacement, making maintenance more convenient. Attached Figure Description

[0021] The quick-release seat mechanism for tricycles according to this utility model is described below with reference to the accompanying drawings.

[0022] In Embodiment 1 of this application, as Figures 1 to 5 As shown, this quick-release seat mechanism for tricycles (hereinafter referred to as "the present invention") includes a seat cushion 1, an upper seat bucket 2, a lower seat bucket 3, a frame 4, a buckle 5, and a deflector 6. The lower seat bucket 3 is fixedly installed on the pedal of the frame 4. The upper seat bucket 2, which can be flipped forward, is installed at the front of the lower seat bucket 3 via a pivot. The upper seat bucket 2 and the lower seat bucket 3 are locked by the buckle 5. The joint between the upper seat bucket 2 and the lower seat bucket 3 is lower at the front and higher at the back. A fixing hook hole 21 is opened at the front of the upper surface of the upper seat bucket 2. A guide cone 22 is fixedly installed at the rear of the upper surface of the upper seat bucket 2. The fixing hook 11 at the bottom of the seat cushion 1 is inserted into the fixing hook hole 21. The guide cone 22 is sleeved in the guide cone hole 12 at the bottom of the seat cushion 1. The spring pin 14 on the fixed tail plate 13 at the rear of the seat cushion 1 is inserted into the pin hole at the rear of the upper seat bucket 2.

[0023] The utility model patent CN203094291U discloses a fuel tank assembly structure for a hybrid electric tricycle (hereinafter referred to as "the patent"). This patent connects the lower end of the seat bucket to the front upper tube of the frame via a seat bucket hinge, forming a structure that can be flipped open to expose the fuel tank, thus providing a window for maintenance. However, this patent can only open the seat bucket part, meaning that during maintenance, the staff can only access the window in the area directly below the seat bucket. In actual maintenance, the window space is relatively small, making operation inconvenient. In contrast, this invention separates the traditional seat bucket into an upper seat bucket 2 and a lower seat bucket 3 for maintenance, and makes the joint between the upper seat bucket 2 and the lower seat bucket 3 lower at the front and higher at the back. This allows the upper seat bucket 2 to be folded forward, exposing a larger engine maintenance window and reducing the difficulty of maintenance.

[0024] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 5 and Figure 6 As shown, a deflector 6 is installed at the front of the lower seat bucket 3. With the help of the deflector 6 at the front of the lower seat bucket 3, the airflow under the vehicle can be redirected during driving, directing it directly towards the engine, effectively improving the engine's operating environment and enhancing heat dissipation efficiency.

[0025] To further optimize the working efficiency of this application and improve the strength of the maintenance upper seat 2, a reinforcing plate 24 is fixedly installed on the inner side of the maintenance upper seat 2 directly below the seat cushion 1. To ensure a more stable closure between the maintenance upper seat 2 and lower seat 3 and reduce the pressure on the pivot between them, a rear limiting plate 23 is fixedly installed at the rear of the maintenance upper seat 2. When the maintenance upper seat 2 and lower seat 3 are closed, the rear limiting plate 23 is engaged with the outer side of the lower seat 3. To further optimize the airflow, a heat dissipation window is provided at the rear of the lower seat 3. To further improve the stability when the maintenance upper seat 2 and lower seat 3 are closed, a groove corresponding to the lower edge of the maintenance upper seat 2 is provided on the upper edge of the lower seat 3. Multiple reinforcing beams are provided on the inner sides of the maintenance upper seat 2 and lower seat 3.

[0026] When in use, simply install the quick-release seat mechanism suitable for tricycles, and the equipment is ready for use.

[0027] When this utility model is used, its specific operation is as follows:

[0028] When maintenance is required, simply open latch 5 and push the upper maintenance seat 2 forward. The upper maintenance seat 2 will fold forward along the pivot, revealing a large maintenance window. Because the lower maintenance seat 3 is lower in the front and higher in the back, maintenance personnel can better observe the front of the engine. After maintenance is completed, pull the upper maintenance seat 2 back to its original position, and then use latch 5 to lock the upper maintenance seat 2 and the lower maintenance seat 3.

[0029] In summary, the quick-release seat mechanism for tricycles according to this utility model separates the traditional seat bucket into an upper inspection seat bucket 2 and a lower inspection seat bucket 3, and makes the seam between the upper and lower inspection seat buckets 2 and 3 lower at the front and higher at the back. This allows a larger engine inspection window to be exposed when the upper inspection seat bucket 2 is folded forward, reducing the difficulty of maintenance. Simultaneously, the air deflector 6 located at the front of the lower inspection seat bucket 3 redirects the airflow under the vehicle during driving, directing it directly at the engine, effectively improving the engine's operating environment and enhancing heat dissipation efficiency. Furthermore, the easily removable seat cushion 1 significantly reduces the difficulty of replacement, making maintenance more convenient.
