Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a saddle and a two-wheeled electric vehicle. Background Technology

[0002] Two-wheeled electric vehicles are a popular and convenient mode of transportation. Currently, the saddles of two-wheeled electric vehicles on the market consist of a plastic base, foam, and leather. These materials are highly flammable; therefore, in the event of a fire, the saddle of a two-wheeled electric vehicle will burn rapidly, not only exacerbating the spread of the fire but also potentially producing toxic and harmful gases, posing a serious threat to people's lives.

[0003] Therefore, consumer demand is gradually shifting towards reducing flammable materials on vehicles. Furthermore, the "Safety Technical Specifications for Electric Bicycles," which will officially come into effect on September 1, 2025, stipulates that the total mass of plastic parts in the vehicle must not exceed 5.5% of the total vehicle mass, and all plastic parts must have flame-retardant properties.

[0004] In response to changing consumer demands and regulations, this application provides a new saddle structure. Utility Model Content

[0005] To address the aforementioned problems, embodiments of this application provide a saddle and a two-wheeled electric vehicle, which at least partially solve the problems described above.

[0006] In a first aspect, this application provides a saddle for a two-wheeled electric vehicle, comprising: Metal base The decorative part includes a ring-shaped body, a connecting ear plate, and a clearance opening provided on the ring-shaped body. The ring-shaped body is connected to the lower part of the metal base, and the connecting ear plate is provided on the lower surface of the ring-shaped body for connecting to the frame of the two-wheeled electric vehicle. The adapter includes an adapter portion and a snap-fit ​​portion, the adapter portion being located at the upper end of the adapter and connected to the metal base via the clearance opening. The snap-fit ​​part is located at the lower end of the adapter. When the saddle is installed on the frame of the two-wheeled electric vehicle, the snap-fit ​​part is used to snap into the frame of the two-wheeled electric vehicle via the clearance opening.

[0007] Secondly, this application provides a two-wheeled electric vehicle, which includes a frame and the aforementioned saddle. The frame includes a first bracket and a second bracket. The first bracket includes a slot with a rearward opening. The snap-fit ​​portion is inserted into the slot in a rear-to-forward direction. The ring-shaped body is stacked on the upper surfaces of the first bracket and the second bracket. The connecting ear plate is located on the rear side of the second bracket and is detachably connected to the rear side of the second bracket.

[0008] In the saddle structure provided in this application, by setting a ring-shaped main body and a clearance opening on the decorative part, on the one hand, the existence of the clearance opening reduces the amount of material used in the decorative part, thereby reducing the proportion of material used in the decorative part in the entire saddle. Since the decorative part is mostly made of plastic, the proportion of plastic used in the entire saddle can be reduced. Moreover, when the adapter is connected to the frame, the ring-shaped main body surrounding the adapter can serve to cover the decoration. On the other hand, the metal base can be directly connected to the frame of the two-wheeled electric vehicle through the adapter and the clearance opening, and the decorative part can be directly connected to the frame of the two-wheeled electric vehicle through the connecting ear plate, making the connection between the entire saddle and the frame more reliable.

Detailed Implementation

[0021] To provide a clearer understanding of the technical features, objectives, and effects of the embodiments of this application, the specific implementation methods of the embodiments of this application will now be described with reference to the accompanying drawings.

[0022] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0023] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown as one or more, or only one or more are labeled.

[0024] In one aspect, this application provides a saddle with a structure that not only reduces the proportion of plastic but also facilitates the assembly of the saddle onto the frame of a two-wheeled electric vehicle.

[0025] It needs to be clarified that, for ease of description, this application defines a frame orientation system based on the two-wheeled electric vehicle being ridden. "Up" and "down" are defined according to the direction of gravity, "front" and "rear" are defined based on the handlebars and saddle of the two-wheeled electric vehicle, with the handlebars in front and the saddle in the rear, and "left" and "right" are based on the rider's left hand side being left and right hand side being right when riding the two-wheeled electric vehicle. Then, the orientation of each part of the saddle is described according to the defined frame orientation system.

[0026] For details, please refer to Figures 1 to 3 ,as well as Figure 5 and Figure 6 The saddle provided in this application includes a metal base 10, a decorative part 20, and an adapter 30. The decorative part 20 includes a ring-shaped body 21, a connecting ear plate 22, and a clearance opening 23 disposed on the ring-shaped body 21. The ring-shaped body 21 is connected to the lower part of the metal base 10. The connecting ear plate 22 is disposed on the lower surface of the ring-shaped body 21 and is used to connect with the frame of the two-wheeled electric vehicle. The adapter 30 includes an adapter part 32 and a snap-fit ​​part 33. The adapter part 32 is located at the upper end of the adapter 30 and is connected to the metal base 10 via the clearance opening 23. The snap-fit ​​part 33 is located at the lower end of the adapter 30. When the saddle is installed on the frame of the two-wheeled electric vehicle, the snap-fit ​​part 33 is used to snap-fit ​​with the frame of the two-wheeled electric vehicle via the clearance opening 23.

[0027] In the saddle structure provided in this application, by providing a ring-shaped main body 21 and a clearance opening 23 on the decorative part 20, on the one hand, the presence of the clearance opening 23 reduces the material used in the decorative part 20, thereby reducing the material proportion of the decorative part 20 in the entire saddle. Since the decorative part 20 is mostly made of plastic, the material proportion of plastic in the entire saddle can be reduced. Moreover, when the adapter 30 is connected to the frame, the ring-shaped main body 21 surrounding the adapter 30 can play a role in concealing the decoration. On the other hand, the metal base 10 can be directly connected to the frame of the two-wheeled electric vehicle through the adapter 30 and the clearance opening 23, and the decorative part 20 can be directly connected to the frame of the two-wheeled electric vehicle through the connecting ear plate 2, making the connection between the entire saddle and the frame more reliable.

[0028] Furthermore, when assembling the saddle onto the frame, the adapter 30, trim piece 20, metal base 10, and flexible seat 40 can be assembled together to form the saddle. The saddle is then fitted onto the corresponding mounting component of the frame through the clearance slot 23. The saddle can then be pushed to engage the snap-fit ​​portion 33 of the adapter 30 with the frame. Finally, the connecting lug 22 is connected to the frame. Clearly, compared to the traditional process of sequentially installing the metal base and trim piece onto the frame, this assembly process of first assembling the entire saddle and then installing it onto the frame is simpler and more efficient, and also facilitates saddle replacement or repair for the user.

[0029] To improve user comfort, refer to Figure 2 and Figure 3 The saddle may also include a flexible seat cushion 40, which is connected to the metal base 10 and / or the trim piece 20. The flexible seat cushion 40 at least covers the upper surface of the metal base 10. In this way, the rider sits directly on the flexible seat cushion 40 while riding, which can effectively improve riding comfort.

[0030] In addition, the flexible seat 40 is connected to the metal base 10 and / or the trim piece 20, covering at least the upper surface of the metal base 10, which can provide riders with a comfortable riding experience and also increase the durability of the saddle to a certain extent.

[0031] To improve the aesthetics of the saddle, in one example, the outer contour of the ring-shaped body 21 matches the outer contour of the metal base 10. This makes the overall structure more harmonious and enhances the saddle's appearance. In another example, the ring-shaped body 21 can be constructed as a one-piece molded ring structure, thus making the outer surface of the ring-shaped body 21 smoother and cleaner, improving the appearance of the decorative part 20. Correspondingly, the connecting ear plate 22 can be connected to the ring-shaped body 21 by welding, threaded connection, or other methods. In one example, the snap-fit ​​portion 33 of the adapter 30 can extend into the clearance opening 23 without protruding beyond the clearance opening 23. The snap-fit ​​connection between the snap-fit ​​portion 33 and the frame can be located exactly within the clearance opening 23, thus allowing the decorative part 20 to cover and decorate the snap-fit ​​connection.

[0032] In addition, the decorative part 20 itself can be constructed as a one-piece structure, that is, the ring-shaped main body 21 and the connecting ear plate 22 are one-piece molded.

[0033] To ensure a more stable and reliable load-bearing capacity for the saddle on the frame, in one possible embodiment, the adapter 30 further includes a connecting body 31. An adapter portion 32 and a snap-fit ​​portion 33 are respectively connected to the upper and lower ends of the connecting body 31, and the snap-fit ​​portion 33 is connected to the front side of the connecting body 31. When the snap-fit ​​portion 33 snaps into the frame of the two-wheeled electric vehicle, the lower surface of the connecting body 31 can overlap the upper surface of the frame. Based on this embodiment, since the metal base 10 can be directly snapped into the frame via the adapter 30 and the clearance opening 23, and the snap-fit ​​portion 33 is connected to the front side of the connecting body 31, it can provide clearance, allowing the lower surface of the connecting body 31 to overlap the upper surface of the frame, thus enabling the metal base 10 to be directly supported by the frame via the adapter 30. In this way, the adapter 30 can both provide a snap-fit ​​and limit function and transmit load-bearing force, allowing the saddle to be installed more stably and reliably on the frame.

[0034] In one possible implementation, refer to Figures 5 to 7The adapter 30 includes a locating protrusion 321 and an adapter hole 322. The metal base 10 has a first locating hole 11 and a first connecting hole 12. The locating protrusion 321 is inserted into the first locating hole 11 in a vertically aligned manner. The saddle also includes a first fastener 51, which passes through the first connecting hole 12 on the metal base 10 and is threaded into the adapter hole 322. Based on this technical solution, the adapter 30 achieves positioning and assembly with the metal base 10 through the locating protrusion 321, thus limiting the relative position between the adapter 30 and the metal base 10 in a plane perpendicular to the vertical direction. Furthermore, the first fastener 51 ensures a stable connection with the metal base 10.

[0035] Indicatively, the first fastener 51 may be a self-tapping screw.

[0036] In one possible embodiment, reference Figure 2 ,as well as Figures 6 to 8 The adapter 30's adapter portion 32 also includes a hook 323, and the metal base 10 is also provided with a snap-fit ​​groove 13. The hook 323 is inserted into the snap-fit ​​groove 13 in the vertical direction and hooks onto the rear edge of the snap-fit ​​groove 13. Based on this technical solution, the hook 323 can be inserted into the snap-fit ​​groove 13 first in the vertical direction, and then pushed in the front-to-back direction so that the hook 323 can hook onto the rear edge of the snap-fit ​​groove 13. After the hook 323 hooks onto the rear edge of the snap-fit ​​groove 13, the positioning protrusion 321 can be aligned and inserted into the positioning hole. Since the hook 323 hooks onto the metal base 10, the adapter 30 will not fall off the metal base 10. At this time, the first fastener 51 can be threaded onto the metal base 10 after passing through the adapter hole 322. Therefore, by providing the hook 323, the positioning and assembly between the adapter 30 and the metal base 10 can be facilitated.

[0037] In one example, reference Figure 8 and Figure 9 The snap-fit ​​groove 13 includes a first cavity 13a and a second cavity 13b distributed along the front-to-back direction. The inner diameter of the first cavity 13a is larger than the inner diameter of the second cavity 13b. The snap hook 323 is inserted into the first cavity 13a and can slide from the first cavity 13a to the second cavity 13b in the front-to-back direction. The snap hook 323 hooks onto the rear edge of the second cavity 13b. Thus, by setting the first cavity 13a to be larger, it is convenient to insert the snap hook 323, while the second cavity 13b with a smaller inner diameter ensures that the snap hook 323 and the rear edge of the snap-fit ​​groove 13 can be reliably hooked, that is, it ensures that the snap hook 323 and the metal base 10 can be reliably hooked.

[0038] The number of hooks 323 can be multiple, and the locking slots 13 and hooks 323 can correspond one-to-one. For example, there can be three hooks 323, which are arranged in a triangle.

[0039] The number of positioning protrusions 321 can be multiple, and each positioning protrusion 321 can correspond to a positioning hole. For example, there can be two positioning protrusions 321, which are spaced apart in the left-right direction.

[0040] In one example, two positioning protrusions 321 are located in front of three hooks 323.

[0041] In one example, the adapter hole 322 may be surrounded by multiple hooks 323.

[0042] To facilitate the engagement between the latching part 33 and the frame, in one possible implementation, refer to... Figure 2 and Figure 7 The latching part 33 includes a latch tongue for inserting into a slot on the frame of the two-wheeled electric vehicle. The upper surface of the latch tongue can extend obliquely downwards and forwards. This obliquely downwards and forwards acting as a guide when inserting the latch tongue into the slot on the frame (e.g., slot 61 below), directs the latch tongue in a direction from the rear-upwards to the lower-frontwards, reducing assembly difficulty and improving assembly efficiency. Simultaneously, after insertion into the slot, the latch tongue can be contained within it, with its upper surface and the slot abutting against each other in both vertical and horizontal directions, thus limiting the saddle's movement in these directions. In practical applications, the inner surface of the slot can form an inclined surface that mates with the upper surface of the latching part 33. When the saddle needs to be disassembled, the wedge-shaped structure formed by the inclined surface and the inclined surface of the slot allows for quick separation by applying a small force upwards and backwards, significantly reducing maintenance difficulty.

[0043] In one example, reference Figures 5 to 6 The connecting body 31 of the adapter 30 is provided with a rearward-opening weight-reducing groove 311. The portions of the connecting body 31 located on the left and right sides of the weight-reducing groove 311 overlap the upper surface of the first bracket 60. In this way, the weight of the adapter 30 can be reduced by setting the weight-reducing groove 311, thereby reducing the weight of the entire saddle. At the same time, it can ensure that the portions of the connecting body 31 located on the left and right sides of the weight-reducing groove 311 have sufficient area to overlap the upper surface of the first bracket 60, ensuring the connection stability between the connecting body 31 and the first bracket 60, so that the first bracket 60 can stably support the connecting body 31.

[0044] Indicatively, the weight-reducing groove 311 can extend through the vertical direction of the connecting body 31, that is, the weight-reducing groove 311 is a through groove, which can reduce the weight of the adapter 30 to the greatest extent.

[0045] Schematic, the latch is only provided on the lower half of the front side of the connecting body 31, the upper half of the front side of the connecting body 31 can abut against the end face of the opening of the adjacent slot 61 of the first bracket 60, and the upper surface of the latch can abut against the inner surface of the slot 61.

[0046] In one possible implementation, refer to Figure 4 and Figure 10 The circular body 21 includes a circular side plate 211 and a circular middle plate 212. The circular side plate 211 extends generally in the vertical direction, and the circular middle plate 212 is connected to the upper edge of the circular side plate 211. The circular middle plate 212 is generally perpendicular to the vertical direction and extends toward the middle area of ​​the circular side plate 211. The clearance opening 23 is provided on the circular middle plate 212, and the connecting ear plate 22 is connected to the lower surface of the circular middle plate 212. When the saddle is installed on the frame of the two-wheeled electric vehicle, the circular middle plate 212 is used to stack between the upper surface of the frame of the two-wheeled electric vehicle and the metal base 10.

[0047] Through the above technical solution, in the circular body 21 of the decorative part 20, the circular side plate 211 can surround the adapter 30 to serve as a decorative cover. The circular middle plate 212 can be supported by the frame, thereby supporting the metal base 10, resulting in a larger surface area of ​​the saddle directly supported by the frame, which helps to ensure that the saddle has sufficient load-bearing capacity.

[0048] Schematic, the saddle can be supported by the frame via the connecting body 31 of the adapter and the circular center plate 212 of the decorative piece 20.

[0049] In one possible implementation, refer to Figure 4The metal base 10 and the decorative piece 20 each have a plurality of second positioning holes 14 on one side and a plurality of positioning posts 24 on the other side. The second positioning holes 14 and the positioning posts 24 correspond one-to-one, and the positioning posts 24 can be inserted into the second positioning holes 14 in a shape-fitting manner. The plurality of positioning posts 24 are distributed at intervals around the clearance opening 23. The metal base 10 and the decorative piece 20 each have a plurality of second connecting holes 15 on one side and a plurality of third connecting holes 210 on the other side. The plurality of third connecting holes 210 are distributed at intervals around the clearance opening 23. The saddle also includes a second fastener 52, which passes through the second connecting hole 15 and is connected to the third connecting hole 210, or the second fastener 52 passes through the third connecting hole 210 and is connected to the second connecting hole 15. Thus, through this technical solution, the one-to-one insertion of the positioning posts 24 and the second positioning holes 14 allows for rapid positioning of the metal base 10 and the decorative part 20 during assembly. The second fastener 52 then reliably connects the metal base 10 and the decorative part 20 together, improving assembly efficiency. Furthermore, the multiple positioning posts 24, spaced apart around the clearance opening 23, ensure a more stable connection between the metal base 10 and the decorative part 20, resulting in more even force distribution and preventing loosening or damage due to excessive localized stress.

[0050] Schematic, the third connecting hole 210 can be provided on the circular middle plate 212 of the decorative piece 20, so that the metal base 10 and the circular middle plate 212 can be directly connected.

[0051] Schematic, the second fastener 52 can be a self-tapping screw.

[0052] To facilitate the connection of the connecting lug 22 to the frame, and to ensure that the saddle 22 can be reliably positioned on the frame, a fourth connecting hole 220 can be provided on the connecting lug 22, and the fourth connecting hole 220 extends through the connecting lug 22 in the front-to-back direction. Thus, for reference... Figure 10 Through size design, after the adapter 30 is snapped onto the vehicle frame, the connecting lug 22 is located on the rear side of the frame, and a third fastener 53 enables a detachable connection between the connecting lug 22 and the rear side of the frame. For example, refer to... Figure 3 , Figure 4 and Figure 10 The third fastener 53 can be a bolt and nut assembly. The frame has a second bracket 70, and a threaded connection hole 701 is provided on the rear side of the second bracket 70. After the third fastener 53 passes through the fourth connection hole 220 of the connecting ear plate 22, it is threaded into the threaded connection hole 701 of the second bracket 70, so as to achieve a stable connection between the connecting ear plate 22 and the second bracket 70. When disassembly is required, simply unscrew the bolt.

[0053] Secondly, based on such a saddle structure, this application also provides a two-wheeled electric vehicle, which includes a frame and the aforementioned saddle. The frame includes a first bracket 60 and a second bracket 70. The first bracket 60 includes a slot 61 with an opening facing rearward. A snap-fit ​​portion 33 is inserted into the slot 61 in a rear-to-forward direction. A ring-shaped body 21 is stacked on the upper surfaces of the first bracket 60 and the second bracket 70. A connecting ear plate 22 is located on the rear side of the second bracket 70 and is detachably connected to the rear side of the second bracket 70.

[0054] Based on the above technical solution, by inserting the snap-fit ​​portion 33 of the adapter 30 into the slot 61 of the first bracket 60 of the frame in a rear-to-forward direction, the front side of the connecting body 31 can abut against the first bracket 60, thereby restricting the adapter 30 from moving forward further. The slot 61 can restrict the degree of freedom of the snap-fit ​​portion 33 in the vertical and horizontal directions. Furthermore, with the assistance of the connecting ear plate 22 and the second bracket 70, the saddle is reliably positioned on the frame. In addition, the first bracket 60 and the second bracket 70 can support the ring-shaped body 21 of the decorative piece 20, thereby indirectly supporting the metal base 10 and ensuring the saddle's load-bearing capacity. This allows the saddle to be reliably installed on the frame. Therefore, the first bracket 60 and the second bracket 70 can reliably and stably install the saddle on the frame and facilitate its removal from the frame.

[0055] Furthermore, based on the aforementioned beneficial effects of the saddle, the two-wheeled electric vehicle provided in this application has the following beneficial effects: This reduces the proportion of plastic used in the vehicle, not only decreasing flammable materials and lowering the fire risk, but also complying with the "Electric Bicycle Safety Technical Specifications" regarding the total mass and flame-retardant performance of plastic components, thus improving vehicle safety and compliance. It also simplifies the assembly and disassembly process of the saddle and frame, improving production efficiency and making it easier for users to replace or repair the saddle.

[0056] Schematic illustration: the first support 60 can be located in front of the second support 70. There can be one first support 60 and two second supports 70, so that the saddle can be stably supported by the three supports.

[0057] In one possible implementation, refer to Figure 5 and Figure 6The first support 60 includes an abutment portion 62 and two load-bearing portions 63. A slot 61 is disposed on the abutment portion 62, and the two load-bearing portions 63 are connected to the rear side of the abutment portion 62 and are located on the left and right sides of the slot 61, respectively. The upper surface of the locking portion 33 contacts the abutment portion 62, and the adapter 30 is stacked on the upper surfaces of the two load-bearing portions 63. Through this technical solution, the abutment portion 62 can cooperate with the locking portion 33 of the adapter 30 through the slot 61, restricting the movement of the adapter 30 in the left-right, front-back, and up-down directions. The two load-bearing portions 63 support the adapter 30 from the left and right sides, making the force on the adapter 30 more even and enhancing the stability of the connection between the saddle and the frame. This structural design allows the saddle to more effectively distribute the force to the frame when bearing the rider's weight, reducing local stress concentration and improving the overall durability and reliability of the structure.

[0058] As described above, the adapter 30 may also include a connecting body 31. Therefore, schematically, when the snap-fit ​​part 33 snaps into the frame of the two-wheeled electric vehicle, the lower surface of the connecting body 31 can overlap the upper surface of the first bracket 60. In this way, the first bracket 60 can not only support the metal base 10 through the adapter 30, but also restrict the degrees of freedom of the adapter 30 in the front-back, left-right, and up-down directions. Schematally, the connecting body 31 overlaps the upper surfaces of the two load-bearing parts 63 of the first bracket 60.

[0059] In one possible implementation, refer to Figure 10 and Figure 11 The second bracket 70 includes a first mounting plate 71, a second mounting plate 72, and a third mounting plate 73. Both the first and second mounting plates 71 and 72 extend vertically and are connected in an L-shape. The third mounting plate 73 is perpendicular to the vertical direction and is also connected in an L-shape to both the first and second mounting plates 71 and 72. The upper surface of the third mounting plate 73 supports the saddle (e.g., the ring-shaped body 21 of a load-bearing saddle). The first mounting plate 71 connects to the connecting lug 22 of the saddle. That is, the rear side of the first mounting plate 71 is the rear side of the second bracket 70. Through this technical solution, the first mounting plate 71, the second mounting plate 72, and the third mounting plate 73 support each other, resulting in greater structural strength for the second bracket 70, while also providing installation space for the connection between the connecting lug 22 of the saddle and the rear surface of the second bracket 70.

[0060] In one example, the two-wheeled electric vehicle also includes a battery and an electric motor. The battery can be repeatedly charged and discharged, the electric motor is electrically connected to the battery to obtain electrical energy, and the electric motor is drive-connected to the wheels to drive the wheels to rotate.
