Abstract
Description
Technical Field
[0001] The embodiments of the present utility model relate to the field of household appliances, and more specifically, to a flip seat for a rear bucket of a tricycle. Background Art
[0002] With increasing urban traffic pressure and heightened environmental awareness, electric tricycles are becoming an increasingly popular choice due to their convenience and environmental friendliness. They are widely used for short-distance transportation and in family life. However, when carrying passengers or cargo, existing tricycles lack proper protection on the rear seat edge, which can cause damage to passengers or cargo.
[0003] The reversible rear seat of an existing tricycle includes: a main support plate, which stands upright in the tricycle's compartment; a top plate, which is parallel to the tricycle's compartment and connected to the main support plate; and a side plate assembly, which includes a first side support plate and a second side support plate, which are respectively fixedly connected to the main support plate on both sides along the length direction, the first side support plate and the second side support plate are both fixedly connected to the top plate, and the main support plate and the compartment are connected in a hinged manner. When the tricycle is carrying people, the main support plate, the first side support plate and the second side support plate support the top plate, and the front area of the tricycle's compartment serves as a leg-accommodating space for the passengers; when the tricycle is carrying cargo, the main support plate is laid flat until it abuts the bottom wall of the compartment, and the first side support plate, the second side support plate, the top plate and the rear area of the compartment together constitute the cargo area.
[0004] To reduce the risk of damage to passengers or cargo during use, existing tricycles typically weld metal sheets to the edges of the rear seats to form protective edge guards. While this method provides a certain level of structural strength, it also has several drawbacks. First, the welding process can cause deformation, affecting the smoothness and aesthetics of the edge guards. Second, welded joints are prone to rust, impacting the product's corrosion resistance and service life. Furthermore, the high cost of the welding process hinders large-scale production and cost reduction. Utility Model Content

The provision of reinforcing ribs also improves structural durability, reducing fatigue damage under long-term loads.
[0009] In one embodiment, the top panel and the side panel components are made of stainless steel, aluminum, wood, engineering plastics or high-strength plastics.
[0010] In one embodiment, the edge protection formed by the curling of the first side branch plate and the second side branch plate includes the following shapes: circle, rectangle, chamfer, bevel, arc, polygon or a combination of at least two of the above shapes.
[0011] In one embodiment, the first side support plate includes a first straight edge fixedly connected to the inner side wall of the top plate, a second straight edge fixedly connected to the inner side wall of the main support plate, and a first arc edge formed between the first straight edge and the second straight edge; the second side support plate includes a third straight edge fixedly connected to the inner side wall of the top plate, a fourth straight edge fixedly connected to the inner side wall of the main support plate, and a second arc edge formed between the third straight edge and the fourth straight edge.

[0015] In one embodiment, at least one locking hole is provided on the top plate for installing a locking member for fixing the top plate and the compartment side wall.
[0016] In one embodiment, a hydraulic or pneumatic power assist system is further included to assist the flipping action of the top plate.
[0017] The flip seat of the rear bucket of a three-wheeled vehicle provided above, which uses a first side support plate and a second side support plate edge guard formed by a curling process, significantly improves the corrosion resistance of the flip seat of the rear bucket of the three-wheeled vehicle compared to traditional welding methods.

DETAILED DESCRIPTION
[0023] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0024] The present invention provides a flip seat 100 for a rear bucket of a tricycle, Figure 1 Among them, the flip-up design of the rear seat of a tricycle is widely used because it takes into account the two most commonly used functions in life: carrying cargo and carrying people.
[0025] Reference Figure 1 and Figure 2 The flip plate edge guard 4 includes a main support plate 1 erected in the compartment of the tricycle, a top plate 2, a top plate 2 parallel to the compartment of the tricycle and connected to the main support plate 1 by a rounded corner, and a side plate assembly 3. The side plate assembly 3 includes a first side support plate 31 and a second side support plate 32 respectively fixedly connected to both sides of the main support plate 1 along the length direction, and the first side support plate 31 and the second side support plate 32 are both fixedly connected to the top plate 2. Among them, the main support plate 1 and the compartment are connected in a hinged manner, and the edges of the first side support plate 31 and the second side support plate 32 are both formed with edge guards 4 by curling (refer to Figure 3 ). Preferably, the top plate 2, the first side support plate 31, and the second side support plate 32 are all made of stainless steel, aluminum, wood, engineering plastic, or high-strength plastic. To further enhance corrosion resistance, the surfaces of the main support plate 1, the top plate 2, and the first side support plate 31 and the second side support plate 32 are coated with an anti-corrosion coating such as epoxy resin coating, polyurethane coating, acrylic coating, or inorganic zinc silicate coating.
[0026] The use process of the flip plate of the tricycle in the two states of carrying people and loading cargo is as follows: when the tricycle is carrying people, the main support plate 1, the first side support plate 31 and the second side support plate 32 support the top plate 2, and the front area of the tricycle's compartment serves as the leg accommodation space for the passengers; when the tricycle is carrying cargo, the main support plate 1 needs to be laid flat until the main support plate 1 and the bottom wall of the compartment are in contact with each other. At this time, the first side support plate 31, the second side support plate 32, the top plate 2 and the rear area of the compartment together constitute the cargo area.
[0027] Based on the above description, by forming the edge guards 4 on the first side support plate 31 and the second side support plate 32 using a crimping process, compared to traditional welding methods, welding points can be eliminated, thereby avoiding the problem of welding points serving as starting points for corrosion. This improves the corrosion resistance of the improved flip seat 100, enhances the service life of the flip seat 100, and enhances the passenger experience. Furthermore, processing the edge guards 4 using a crimping process improves processing efficiency compared to traditional welding processes, reduces the potential for defects during welding, and reduces the workload during subsequent corrections, thereby reducing manufacturing costs and improving work efficiency.
[0028] The first side support plate 31 and the second side support plate 32 edge guard 4 formed by the hemming process significantly improve the corrosion resistance of the flip seat 100 of the rear bucket of the three-wheeled vehicle compared to traditional welding methods. This innovative design effectively eliminates welding points, thereby reducing the risk of welding points serving as a starting point for corrosion, enhancing the durability and reliability of the rear seat, extending the service life of the product, and significantly improving the passenger experience. In addition, the hemming process demonstrates higher efficiency in processing the edge guard 4. Compared with traditional welding processes, the hemming process simplifies the production process, reduces defects that may occur during welding, and reduces the need for subsequent correction work. This not only reduces material waste, but also shortens the production cycle, reduces manufacturing costs, and improves overall work efficiency.
[0029] In this embodiment, the main support plate 1 is provided with a first hinge and a mounting hole 11 for mounting the first hinge. A second hinge is provided within the vehicle compartment, cooperating with the first hinge to enable the main support plate 1 to flip. Compared to other hinged connections, this hinged connection occupies less space, whether the rear seat is folded flat or open. Furthermore, the hinged connection is more convenient to install and maintain, while also offering lower manufacturing costs, facilitating large-scale manufacturing and widespread adoption.
[0030] Preferably, the main support plate 1, top plate 2, and side panel assembly 3 are all equipped with reinforcing ribs on the side facing the vehicle compartment. These ribs enhance the strength and rigidity of the entire rear seat structure, while also improving its stability and reducing deformation and vibration during use, thereby ensuring passenger comfort and safety. The ribs also enhance structural durability, reducing fatigue damage under long-term loads.
[0031] In this embodiment, the first side support plate 31 includes a first straight edge 311 fixedly connected to the inner sidewall of the top plate 2, a second straight edge 312 fixedly connected to the inner sidewall of the main support plate 1, and a first arc edge 313 formed between the first straight edge 311 and the second straight edge 312. The second side support plate 32 includes a third straight edge 321 fixedly connected to the inner sidewall of the top plate 2, a fourth straight edge 322 fixedly connected to the inner sidewall of the main support plate 1, and a second arc edge 323 formed between the third straight edge 321 and the fourth straight edge 322.
[0032] The first arc edge 313 can connect the first straight edge 311 and the second straight edge 312 in a relatively smooth manner, and the second arc edge 323 can also connect the third straight edge 321 and the fourth straight edge 322 in a relatively gentle manner, so that the first side support plate 31 and the second side support plate 32 can provide a softer transition when contacting with cargo or passengers, thereby significantly reducing the damage that the first side support plate 31 and the second side support plate 32 may cause to the cargo or the potential harm to the passengers when the tricycle is carrying cargo or passengers.
[0033] In this embodiment, the curling of the first and second side support plates 31 and 32 is performed by die curling or rolling. Preferably, the edge guard 4 formed by the curling of the first and second side support plates 31 and 32 includes the following shapes: circular, rectangular, chamfered, beveled, arc, polygonal, or a combination of at least two of the above shapes. Die curling is achieved by using a die and a press to bend the edge along the length of the component, while rolling curling is achieved by using a curling roller controlled by an industrial robot. The present application preferably adopts die curling, which allows multiple components to be formed at one time, and the size and shape after forming are easy to control, which is conducive to large-scale production and cost reduction.
[0034] Preferably, the top panel 2 has at least one locking hole 5 for mounting a locking member that secures the top panel 2 to the side wall of the vehicle compartment. For example, the locking member may be a removable structure such as a buckle or a lock. When the tricycle needs to switch between carrying passengers and cargo, the locking member is released. Once the state transition is complete, the top panel 2 and the side wall of the vehicle compartment are locked together by the locking member.
[0035] In this embodiment, the flip seat 100 further includes a hydraulic or pneumatic power assist system for assisting the flipping of the top plate 2. Since tricycles are mainly used in daily life, the addition of a hydraulic or pneumatic power assist system can effectively reduce the force required by the user to flip the top plate 2, thereby facilitating the operation.
[0036] To sum up, the manufacturing process of the flip seat 100 of the rear bucket of a tricycle mentioned above is simpler and faster, and has better corrosion resistance. It is not only conducive to reducing the manufacturing difficulty and cost of the edge guard 4 of the rear seat flip plate of the tricycle, but also can improve the service life of the edge guard 4 of the rear seat flip plate of the tricycle.
