Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame technology, and in particular to a frame that is easy to fold. Background Technology

[0002] Currently, with the acceleration of urbanization and the diversification of personal travel needs, convenient and environmentally friendly transportation tools are receiving increasing attention. Electric vehicles, in particular, have become an important choice for short-distance travel due to their cleanliness and efficiency. However, the issues of parking and carrying electric vehicles are becoming increasingly prominent, especially for users who need to store or carry their vehicles in limited space. Traditional electric vehicle frame designs lack sufficient flexibility and portability. Furthermore, existing frame designs have shortcomings in folding mechanisms, space occupation, and user experience, necessitating a new frame design to improve the portability and practicality of electric vehicles. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a foldable frame to solve the problem that the existing electric vehicle frames occupy a lot of space and are not portable.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A foldable vehicle frame includes a frame body and a main beam. A seat is provided at the upper end of the frame body, and a base is provided at the lower end of the frame body. A battery box is provided on the base and located below the seat. A rear wheel is provided at the intersection of the base and the frame body. A handlebar assembly is provided at the upper end of the main beam, and a front wheel assembly is provided at the lower end of the main beam. A first folding assembly and a second folding assembly are provided between the frame body and the main beam.

[0006] To achieve the above technical solution, when needed, the frame body and main beam are unfolded, locking the first and second folding components between them to ensure a stable connection. When not in use, the frame body and main beam are folded together using the first and second folding components, forming a compact structure that saves space and facilitates carrying and storage. The seat is positioned at the top of the frame body, while the battery box is located on the base below the seat. This layout helps maintain the frame's balance and low center of gravity, improving stability. The first and second folding components between the frame body and main beam allow the frame to fold when not in use, reducing space occupation. By operating the first and second folding components, the frame body and main beam can be folded close together, achieving a compact storage or carrying configuration, forming a compact structure that saves space.

[0007] In one embodiment of the present invention, the first folding assembly includes a first pivot connecting the left and right sides of the frame body, two crossbeams symmetrically arranged on both sides of the main beam and rotating on the first pivot, and a fixed shaft located outside the main beam connected to the side of the two crossbeams away from the frame body.

[0008] To achieve the above technical solution, when the frame needs to be folded, the crossbeam rotates around the first pivot, causing the crossbeam to move from the unfolded position to a position parallel to or close to the frame body, thus achieving frame folding; the fixed pivot provides support and fixation when the crossbeam is unfolded to its limit position, ensuring structural stability after unfolding and preventing accidental folding of the crossbeam. The design of the first folding component simplifies the folding mechanism and provides good folding and unfolding performance.

[0009] In one embodiment of the present invention, the second folding assembly includes a second rotating shaft connecting the left and right sides of the frame body and located below the first rotating shaft, and two rotating plates symmetrically arranged on both sides of the main beam and rotatably mounted on the second rotating shaft. The two rotating plates are bent upward on the side away from the frame body and connected to a pull rod.

[0010] To achieve the above technical solution, the side of the two rotating plates away from the main body of the frame is bent upward and connected to a pull rod. This design allows the rotating plates to rotate around the second axis by pulling the pull rod upward, so that the rotating plates can move from the unfolded position to a position parallel to or close to the main body of the frame, thereby realizing the folding of the frame. The frame can also be quickly unfolded by pulling the pull rod, which improves the convenience of folding and unfolding the frame.

[0011] In one embodiment of the present invention, a mounting cover located on the outer periphery of the main beam is hinged to the middle of the rotating plate, and a lighting lamp is provided at the front end of the mounting cover.

[0012] To achieve the above technical solution, a light is installed at the front of the mounting cover. This configuration places the light at the front of the frame, providing illumination for the rider on the road ahead. The mounting cover can also rotate along the hinge point in the middle of the swivel plate, making it easy to store.

[0013] In one embodiment of the present invention, the front wheel assembly includes pedals symmetrically arranged on the left and right sides of the main beam, a front wheel frame disposed at the lower end of the main beam, and a front wheel rotatably disposed on the front wheel frame.

[0014] To achieve the above technical solution, the pedals are symmetrically positioned on the left and right sides of the main beam, providing riders with a stable foothold. The design of the front wheel assembly allows the frame to occupy less space when folded, and the optimized folding mechanism of the frame makes the folding process smoother and more reliable.

[0015] In one embodiment of the present invention, the grip assembly includes a curved rod disposed on the upper end of the main beam, a handle disposed on the curved rod, and grip sleeves sleeved on the left and right sides of the handle.

[0016] To achieve the above technical solution, the design of the bend bar and handlebars allows riders to control the vehicle's direction more precisely, and the bend design is also allowed at the connection between the bend bar and the main beam, thereby reducing the space occupied by the handlebar assembly in the folded state.

[0017] In one embodiment of the present invention, the seat includes a seating portion and a backrest portion, and the backrest portion is provided with a pull ring.

[0018] To achieve the above technical solution, the seat consists of two parts: a seating section and a backrest section, which respectively provide the functions of a seat cushion and a backrest. A pull ring is provided on the backrest section, which can be used to pull the seat to unfold the battery box when folding or transporting. The design of the pull ring takes into account the transport of the vehicle frame, allowing the user to easily adjust the position of the vehicle frame.

[0019] As described above, the foldable frame of this utility model has the following advantages: The design of the first and second folding components allows the frame to be folded into a compact structure when not in use, greatly reducing space occupation and facilitating carrying and storage; the design of the first and second folding components makes the folding and unfolding process of the frame simpler and faster, improving user convenience; the seat is located at the upper end of the frame body, and the battery box is located on the base and below the seat; this layout helps maintain the frame's balance and low center of gravity, improving stability during driving; the design of the first and second folding components ensures the structural stability of the frame in the unfolded state, avoiding safety hazards caused by the folding mechanism during use; this application, through optimized structural design, solves the problems existing in the prior art, providing a space-saving, convenient, stable, durable, and environmentally friendly frame with high market competitiveness and promotional value.

Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1 to 2 This utility model provides a foldable vehicle frame, including a frame body 1 and a main beam 2. The frame body 1 has a seat 3 at its upper end and a base 4 at its lower end. The base 4 has a battery box 5 located below the seat 3. A rear wheel 6 is located at the intersection of the base 4 and the frame body 1. The main beam 2 has a handlebar assembly at its upper end and a front wheel 17 assembly at its lower end. A first folding assembly and a second folding assembly are provided between the frame body 1 and the main beam 2.

[0026] When needed, the frame body 1 and main beam 2 are unfolded, locking the first and second folding components between them to ensure a secure connection. When not in use, the frame body 1 and main beam 2 are folded together using the first and second folding components, forming a compact structure that saves space and facilitates carrying and storage. The seat 3 is positioned at the top of the frame body 1, while the battery box 5 is located on the base 4 below the seat 3. This layout helps maintain the frame's balance and low center of gravity, improving stability. The first and second folding components between the frame body 1 and main beam 2 allow the frame to be folded when not in use, reducing space requirements. By operating the first and second folding components, the frame body 1 and main beam 2 can be folded close together, achieving a compact storage or carrying configuration and saving space.

[0027] The first folding assembly includes a first pivot 7 connecting the left and right sides of the frame body 1, two crossbeams 8 symmetrically arranged on both sides of the main beam 2 and rotating on the first pivot 7, and a fixed shaft 9 located on the outside of the main beam 2 connected to the side of the two crossbeams away from the frame body 1.

[0028] When the frame needs to be folded, the crossbeam 8 rotates around the first pivot 7, moving the crossbeam 8 from the unfolded position to a position parallel to or close to the frame body 1, thus folding the frame. The fixed pivot 9 provides support and fixation when the crossbeam 8 is unfolded to its limit position, ensuring structural stability after unfolding and preventing the crossbeam 8 from folding accidentally. The design of the first folding component simplifies the folding mechanism and provides good folding and unfolding performance.

[0029] The second folding assembly includes a second pivot 10 connecting the left and right sides of the frame body 1 and located below the first pivot 7, and two pivot plates 11 symmetrically arranged on both sides of the main beam 2 and rotatably mounted on the second pivot 10. The two pivot plates 11 are bent upward on the side away from the frame body 1 and connected to a pull rod 12.

[0030] The two rotating plates 11 are bent upward on the side away from the frame body 1 and connected to the pull rod 12. This design allows the rotating plates 11 to rotate around the second rotating axis 10 when the pull rod 12 is pulled upward, so that the rotating plates 11 can be moved from the unfolded position to a position parallel to or close to the frame body 1, thereby realizing the folding of the frame. The frame can also be quickly unfolded through the pull rod 12, which improves the convenience of folding and unfolding the frame.

[0031] The rotating plate 11 is hinged to a mounting cover 13 located on the outer periphery of the main beam 2 at the middle. The front end of the mounting cover 13 is provided with a light 14. The mounting cover 13 is equipped with a light 14 at the front end, which makes the light 14 located at the front of the frame to provide illumination for the rider on the road ahead. The mounting cover 13 can also rotate along the hinge point in the middle of the rotating plate 11, so as to facilitate storage.

[0032] The front wheel 17 assembly includes pedals 15 symmetrically arranged on the left and right sides of the main beam 2, a front wheel 17 frame 16 located at the lower end of the main beam 2, and a front wheel 17 rotatably mounted on the front wheel 17 frame 16. The pedals 15, symmetrically arranged on the left and right sides of the main beam 2, provide a stable foothold for the rider. The design of the front wheel 17 assembly allows the frame to occupy less space when folded, optimizing the folding mechanism and making the folding process smoother and more reliable.

[0033] The grip assembly includes a bend bar 18 mounted on the upper end of the main beam 2, a handlebar 19 mounted on the bend bar 18, and handlebar grips 20 fitted on the left and right sides of the handlebar 19. The design of the bend bar 18 and the handlebar 19 allows the rider to control the vehicle direction more precisely, and the connection between the bend bar 18 and the main beam 2 also allows for bending, thereby reducing the space occupied by the grip assembly in the folded state.

[0034] The seat 3 includes a seating section 31 and a backrest section 32, with a pull ring 33 provided on the backrest section 32. The seat 3 consists of two parts, the seating section 31 and the backrest section 32, which respectively provide the functions of a seat cushion and a backrest. The pull ring 33 is provided on the backrest section 32. This pull ring 33 can be used to pull the seat 3 to unfold the battery box 5 when folding or transporting. The design of the pull ring 33 takes into account the transport of the frame, allowing the user to easily adjust the position of the frame.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
