Description
Technical Field
[0001] This utility model relates to the field of transportation technology, and in particular to a flip-up seat cushion storage box and an electric tricycle. Background Technology
[0002] Electric tricycles, with their advantages of energy conservation, environmental protection, high load-bearing capacity, and low operating costs, are widely used in short-distance transportation and cargo transport for urban and rural residents, becoming an important means of transportation to improve travel efficiency and convenience. In the structural design of electric tricycles, for ease of storage, existing electric tricycles typically employ a seat cushion and seat bucket structure. The seat cushion serves as the opening and closing cover of the seat bucket, and the seat cushion and seat bucket are welded and fixed together by a hinge, allowing the seat cushion to rotate around the hinge axis to open and close the seat bucket. However, when the rider needs to place or remove items from the seat bucket, the seat cushion must be flipped upwards to rotate around the hinge to the open position. Furthermore, the seat cushion tends to fall downwards under its own weight. To prevent the seat cushion from falling back and closing, the rider must always use one hand to support the seat cushion to maintain its open position while using the other hand to retrieve or place items. This makes operation very inconvenient and may even cause the seat cushion to fall rapidly due to accidental loosening of the hand, resulting in hand injuries and other safety hazards. Utility Model Content
[0003] The purpose of this utility model is to provide a flip-up seat cushion storage box and an electric tricycle to solve the problems existing in the prior art, improve the convenience of the flip-up seat cushion storage box, and reduce safety hazards.
[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a flip-up seat cushion storage box, including a seat cushion, a seat bucket, and a connecting support assembly. The seat cushion and the seat bucket have an opening on the top surface. The tops of the seat cushion and the seat bucket are rotatably connected around a virtual axis. The tops of the seat cushion and the seat bucket are also connected by a lock body, and there is a distance between the lock body and the virtual axis. The connecting support assembly is connected to the seat cushion and the seat bucket respectively. When the lock body is closed and the seat cushion is in a first position, the seat cushion can cover the top of the seat bucket. When the lock body is open, the connecting support assembly can allow the seat cushion to rotate around the virtual axis and support the seat cushion so that it can stay in a second position, thereby opening the top opening of the seat bucket.
[0005] In some embodiments, the connecting support assembly includes a spring hinge, which includes a first leaf plate and a second leaf plate, a spindle, and an elastic element. The first leaf plate is fixedly connected to the seat cushion, and the second leaf plate is fixedly connected to the seat bucket. Sleeves are provided on adjacent edges of the first and second leaf plates. The spindle is collinear with the virtual axis and passes through the sleeves of the first and second leaf plates to rotatably connect the first and second leaf plates around the spindle. The elastic element is coaxially sleeved on the spindle, and has a first torsion arm and a second torsion arm at both ends. The first torsion arm abuts against the first leaf plate, and the second torsion arm abuts against the second leaf plate. When the first and second leaf plates rotate around the spindle and approach each other, the elastic force of the elastic element can prevent the first and second leaf plates from approaching each other further.
[0006] In some embodiments, the connecting support assembly includes a gas spring, the cylinder end of which is rotatably connected to the seat bucket, and the piston end of which is rotatably connected to the seat cushion. When the lock is open, the gas spring enables the seat cushion to rotate about the virtual axis and supports the seat cushion so that it can remain in the second position.
[0007] In some embodiments, the lock body includes a lock hook and a lock tongue, the lock hook being fixedly connected to the bottom surface of the seat cushion; the bottom end of the lock tongue is rotatably connected to the inner wall of the seat bucket; when the lock body is closed and the seat cushion is in the first position, the top end of the lock tongue can hook the lock hook; when the lock body is open, the top end of the lock tongue rotates around the bottom end of the lock tongue, and the top end of the lock tongue disengages from the lock hook.
[0008] In some embodiments, when the cushion is in the second position, the elastic force of the elastic element is the same as the weight of the cushion.
[0009] In some embodiments, a limiting mechanism is also included, the limiting mechanism comprising a connecting rope, one end of which is fixedly connected to the seat cushion and the other end of which is fixedly connected to the inner wall of the seat bucket. When the angle between the seat cushion and the top surface of the seat bucket reaches 90°, the connecting rope is tightened to prevent the seat cushion from rotating further around the spindle.
[0010] In some embodiments, the number of spring hinges is two, and the two spring hinges are symmetrical about the center line of the edge of the cushion that is parallel to the virtual axis.
[0011] In some embodiments, the surfaces of the first and second leaf plates are coated with an anti-rust coating.
[0012] In some embodiments, the surface of the elastic element and the mandrel are coated with lubricating grease.
[0013] This utility model also provides an electric tricycle, including a frame, a handlebar at the front end of the frame, and a flip-up seat storage box as described in any of the above. The flip-up seat storage box is installed in the middle and rear of the frame.
[0014] The present invention achieves the following technical advantages over the prior art: This utility model provides a flip-up seat cushion storage box and an electric tricycle. The tops of the seat cushion and the seat bucket are rotatably connected around a virtual axis. A lock body connects the tops of the seat cushion and the seat bucket, with a distance between the lock body and the virtual axis. A connecting support assembly connects the lock body to the seat cushion and the seat bucket respectively. When the lock body is closed and the seat cushion is in a first position, the seat cushion covers the top of the seat bucket. When the lock body is open, the connecting support assembly allows the seat cushion to rotate around the virtual axis and supports the seat cushion to remain in a second position. This eliminates the need for manual flipping of the seat cushion to open the seat bucket. After opening the seat bucket, the connecting support assembly supports the seat cushion in the second position, preventing it from falling back to the first position under gravity. This eliminates the need for the driver or passenger to support the seat cushion, improving the convenience of the flip-up seat cushion storage box and reducing safety hazards caused by the seat cushion falling back quickly.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] The purpose of this utility model is to provide a flip-up seat cushion storage box and an electric tricycle to solve the problems existing in the prior art, improve the convenience of the flip-up seat cushion storage box, and reduce safety hazards.
[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Example 1 This embodiment provides a flip-up seat cushion storage box, including: a seat cushion 1, a seat bucket 2, and a connecting support assembly 3. The top surface of the seat bucket 2 is open. The tops of the seat cushion 1 and the seat bucket 2 are rotatably connected around a virtual axis. The tops of the seat cushion 1 and the seat bucket 2 are also connected by a lock body 4, which is spaced from the virtual axis. The connecting support assembly 3 is connected to the seat cushion 1 and the seat bucket 2 respectively. When the lock body 4 is closed and the seat cushion 1 is in a first position, the seat cushion 1 can cover the top of the seat bucket 2. When the lock body 4 is open, the connecting support assembly 3 can make the seat cushion 1 rotate around the virtual axis and support the seat cushion 1 to stay in a second position. Thus, the top opening of the seat bucket 2 can be opened without manually flipping the seat cushion 1. After the seat bucket 2 is opened, the connecting support assembly 3 can support the seat cushion 1 to stay in the second position. The seat cushion 1 will not fall back to the first position under the action of gravity. Thus, the driver and passenger do not need to hold the seat cushion 1, which improves the convenience of the flip-up seat cushion storage box and reduces the safety hazards caused by the seat cushion 1 falling back quickly.
[0021] Specifically, when the seat cushion 1 is in the first position, the seat cushion 1 covers the top of the seat bucket 2, and the seat bucket 2 is in a closed state. When the seat cushion 1 is in the second position, the top of the seat cushion 1 and the seat bucket 2 are separated, and the seat bucket 2 is in an open state.
[0022] In some embodiments, the connecting support assembly 3 includes a spring hinge, which includes a first leaf plate 31, a second leaf plate 32, a spindle 33, and an elastic element 34. The first leaf plate 31 is fixedly connected to the seat cushion 1, and the second leaf plate 32 is fixedly connected to the seat bucket 2. Sleeves are provided on the adjacent edges of the first leaf plate 31 and the second leaf plate 32. The spindle 33 is collinear with the virtual axis and passes through the sleeves of the first leaf plate 31 and the second leaf plate 32 to rotatably connect the first leaf plate 31 and the second leaf plate 32 around the spindle 33. The elastic element 34 is coaxially sleeved on the spindle 33, and both ends of the elastic element 34 are... The device has a first torsion arm 341 and a second torsion arm 342. The first torsion arm 341 abuts against the first leaf plate 31, and the second torsion arm 342 abuts against the second leaf plate 32. When the lock body 4 is closed, the elastic force of the elastic element 34 is at its maximum. When the lock body 4 is open, the elastic force of the elastic element 34 can cause the seat cushion 1 to spring open and rotate around the spindle 33, allowing the seat bucket 2 to be opened without manual flipping of the seat cushion 1. Furthermore, the elastic force of the elastic element 34 can prevent the first leaf plate 31 and the second leaf plate 32 from getting closer together, thus supporting the seat cushion 1 and keeping it in the second position, preventing it from falling back to the first position under the action of gravity. Specifically, the elastic element 34 is a torsion spring. When the lock body 4 is closed, the torsion spring undergoes elastic deformation, converting the mechanical energy of the seat cushion 1 covering the seat bucket 2 into the elastic potential energy of the torsion spring. When the lock body 4 is open, the elastic potential energy of the torsion spring is converted into the mechanical energy to open the seat cushion 1, causing the seat cushion 1 to spring open and rotate around the spindle 33.
[0023] In some embodiments, the lock body 4 includes a hook 41 and a latch 42. The hook 41 is fixedly connected to the bottom surface of the seat cushion 1 and is close to the second side 12. The bottom end of the latch 42 is rotatably connected to the inner wall of the seat bucket 2 near the fourth side 22. When the lock body 4 is closed and the seat cushion 1 is in the first position, the top end of the latch 42 can hook the hook 41 so that the seat cushion 1 covers the seat bucket 2. When the lock body 4 is open, the top end of the latch 42 rotates around the bottom end of the latch 42, and the top end of the latch 42 separates from the hook 41. Under the elastic force of the elastic hinge, the seat cushion 1 rotates around a virtual axis to open the seat bucket 2, which is convenient for passengers to put or take items into or out of the seat bucket 2. Specifically, a lock cylinder is provided on the side wall of the seat bucket. The bottom end of the latch is fixedly connected to the lock cylinder. After the key is inserted into the lock cylinder, the lock cylinder can drive the latch to rotate around the axis of the lock cylinder to open the lock body.
[0024] In some embodiments, when the seat cushion 1 is in the second position, the elastic force of the elastic element 34 is the same as the weight of the seat cushion 1, and the seat cushion 1 is in a state of force balance. Specifically, when the seat cushion 1 is in the second position, the angle between the seat cushion 1 and the top surface of the seat bucket 2 is 60°. By setting the angle between the first leaf plate 31 and the second leaf plate 32 to 60°, a suitable opening size for the seat bucket 2 is provided for the driver and passenger. In some embodiments, the flip-up seat cushion storage box also includes a limiting mechanism. The limiting mechanism includes a connecting rope, one end of which is fixedly connected to the seat cushion 1, and the other end of which is fixedly connected to the inner wall of the seat bucket 2. When the angle between the seat cushion 1 and the top surface of the seat bucket 2 reaches 85°, the connecting rope is tightened to prevent the seat cushion 1 from rotating further around the spindle 33, thus avoiding excessive rotation angle of the seat cushion 1 from impacting the outer wall of the seat bucket 2 or causing impact on the connection point of the first leaf plate 31 and the second leaf plate 32 of the spring hinge rotating around the spindle 33.
[0025] In some embodiments, there are two spring hinges, which are symmetrical about the center line of the edge of the cushion 1 that is parallel to the virtual axis. The two symmetrically arranged spring hinges provide uniform support force to the cushion 1, so that the cushion 1 is balanced by force and maintains the stability of the cushion 1.
[0026] In some embodiments, the first torsion arm 341 is fixedly connected to the first page plate 31, and the second torsion arm 342 is fixedly connected to the second page plate 32, so as to prevent the elastic force of the elastic element 34 from causing the first torsion arm 341 to separate from the first page plate 31, or the second torsion arm 342 to separate from the second page plate 32, when the lock body 4 is opened.
[0027] In some implementations, the surface of the spring hinge is coated with an anti-rust coating to prevent rainwater from penetrating and causing corrosion, which would affect the smoothness of the spring hinge's rotation.
[0028] In some embodiments, the surface of the elastic element 34 and the spindle 33 are coated with lubricating grease to improve the smoothness of the spring hinge rotation and ensure the smoothness of the elastic element 34 torsion.
[0029] Example 2 The difference between this embodiment and embodiment one is that the connecting support assembly 3 includes a gas spring. The cylinder end of the gas spring is rotatably connected to the seat bucket 2, and the piston end of the gas spring is rotatably connected to the seat cushion 1. When the lock body 4 is closed and the seat cushion 1 is covered on the seat bucket 2, the piston rod is pressed into the cylinder body, and the gas inside the cylinder body is highly compressed, thereby storing potential energy. When the lock body 4 is opened, the high-pressure gas inside the cylinder body expands, generating a continuous outward pushing force on the piston rod, so that the seat cushion 1 rotates around the virtual axis to support the seat cushion 1 so that it stays in the second position.
[0030] Example 3 This embodiment provides an electric tricycle, including a frame, a handlebar at the front of the frame, and a flip-up seat storage box as described in Embodiment 1 or Embodiment 2. The flip-up seat storage box is installed in the middle and rear of the frame. The flip-up seat storage box in the middle of the frame is used for the driver to sit, and the flip-up seat storage box at the rear is used for the passenger to sit. By using the flip-up seat storage box as described in Embodiment 1 or 2 on the tricycle seat, when the storage box is opened, the connecting support component 3 can keep the seat 1 in the second position. The seat 1 will not fall back to the first position under the action of gravity, so that the driver and passenger do not need to hold the seat 1, which improves the convenience of the flip-up seat storage box and reduces the safety hazards caused by the seat 1 falling back quickly.
[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
