Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0043] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0044] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0045] The applicant, through creative labor, discovered that in the relevant technology, such as Figure 1 As shown, in existing bicycle front-end assemblies, the main body of the front-end is mostly "L"-shaped, meaning it includes a horizontal connecting tube 101 and a vertical connecting tube 102 that are perpendicular to each other or at a certain angle. The horizontal connecting tube 101 extends horizontally, while the vertical connecting tube 102 extends vertically. The horizontal tube 200 passes through the horizontal connecting tube 101 to connect the horizontal tube 200 to the front-end main body, while the vertical connecting tube 102 connects to the frame seat tube. This structure has the following problems: it occupies a large amount of space and has a relatively complex structure, which is not conducive to reducing the volume of the front-end assembly and lowering production costs.

[0046] To address the aforementioned technical problems in the related technologies, this application provides the following embodiments to make the structure of the forehead assembly 10 simpler and more compact.

[0047] like Figure 2 and Figure 3 As shown, this application embodiment provides a forehead assembly 10, which includes a forehead body 1 and a horizontal tube 2.

[0048] The front body 1 includes a first cylinder 11 and a second cylinder 12 that are interconnected and coaxially arranged. Both the first cylinder 11 and the second cylinder 12 extend along the first direction Y and are joined in the first direction Y. The second cylinder 12 is adapted to connect to the frame riser tube 20.

[0049] The inner cavity of the first cylinder 11 is used to house the instrument panel, display screen, wiring harness, and other components. When the front assembly 10 is applied to an electric scooter, the second cylinder 12 is used to connect to the top of the frame riser 20 of the electric scooter. For example... Figure 10 As shown, the frame riser 20 is vertically and diagonally positioned at the front of the electric scooter and close to the front wheel assembly 30.

[0050] Both the first cylindrical body 11 and the second cylindrical body 12 are hollow cylindrical structures. The cross-sectional shapes of the first cylindrical body 11 and the second cylindrical body 12 can be the same or different. The cross-sectional shapes of the first cylindrical body 11 and the second cylindrical body 12 can be circular, elliptical, rectangular, pentagonal, or other polygonal shapes. This embodiment uses a circular cross-sectional shape for both the first cylindrical body 11 and the second cylindrical body 12 as an example. It should be noted that the cross-sections of the first cylindrical body 11 and the second cylindrical body 12 are obtained by cutting with a plane perpendicular to the first direction Y. Figure 4 As shown, both the first cylinder 11 and the second cylinder 12 are cylindrical structures and are coaxially arranged.

[0051] Compared to existing technologies Figure 1The forehead body shown is L-shaped. The forehead body 1 provided in this application embodiment is generally a straight cylinder extending along the first direction Y. The structure is more concise, occupies less space, and has a simpler and more beautiful appearance.

[0052] The horizontal tube 2 is passed through the first cylinder 11 and is arranged to intersect with the forehead body 1. The horizontal tube 2 is extended along the second direction X, wherein the second direction X is perpendicular to the first direction Y.

[0053] The two ends of the horizontal tube 2 along its length are used to install handlebars for users to grip and control the steering of the bicycle. The horizontal tube 2 is a hollow cylindrical structure, and its inner cavity can accommodate components such as wiring harnesses.

[0054] Specifically, such as Figure 4 As shown, the first cylindrical body 11 has a third through hole 111 and a fourth through hole 112 arranged opposite to each other along the second direction X, and the horizontal tube 2 is connected to the forehead body 1 through the third through hole 111 and the fourth through hole 112.

[0055] Optionally, the central axis of the horizontal tube 2 intersects with the central axis of the forehead body 1, that is, the horizontal tube 2 passes through the central axis of the forehead body 1; or, the central axis of the horizontal tube 2 is staggered with the central axis of the forehead body 1.

[0056] In existing technologies, such as Figure 1 As shown, the horizontal tube 200 is connected to the first end of the horizontal connecting tube 101, and the vertical connecting tube 102 is connected to the second end of the horizontal connecting tube 101. This results in a large horizontal distance between the horizontal tube 200 and the vertical connecting tube 102, and the forehead assembly 10 occupies a large horizontal space.

[0057] The forehead assembly 10 provided in this application embodiment has a first cylindrical body 11 and a second cylindrical body 12 arranged coaxially, and a horizontal tube 2 passes through the first cylindrical body 11 to be arranged to cross the forehead body 1, which greatly reduces the lateral distance between the horizontal tube 2 and the second cylindrical body 12, so that the space occupied by the forehead assembly 10 in the lateral direction is greatly reduced, and the structure is more compact and simple.

[0058] The front end assembly 10 provided in this application embodiment, by setting the first cylinder 11 and the second cylinder 12 to be arranged and extended along the first direction Y, and by passing the horizontal tube 2 through the first cylinder 11 along the second direction X, greatly reduces the lateral distance between the horizontal tube 2 and the second cylinder 12, and correspondingly reduces the lateral distance between the horizontal tube 2 and the frame upright tube 20, effectively reducing the space occupied by the front end assembly 10, making the structure of the front end assembly 10 more compact and simple; at the same time, the structure of the front end body 1 is simpler, which not only makes the appearance of the front end assembly 10 more concise and beautiful, but also facilitates manufacturing and helps to reduce manufacturing costs.

[0059] In an optional embodiment, the horizontal tube 2 is a separate pipe, which passes sequentially through the third through hole 111 and the fourth through hole 112 of the first cylinder 11, and a portion of the horizontal tube 2 is located in the inner cavity of the first cylinder 11.

[0060] In another alternative embodiment, the horizontal tube 2 includes a first horizontal tube and a second horizontal tube (not shown in the figure), which are respectively connected to the two sides of the first cylinder 11 in the second direction X.

[0061] In this embodiment, the horizontal tube 2 is composed of two separate pipes. The first horizontal tube and the second horizontal tube are coaxially arranged and connected one-to-one to the third through hole 111 and the fourth through hole 112 of the first cylinder 11. This arrangement ensures that the horizontal tube 2 does not occupy the space inside the first cylinder 11, which helps to reduce the size of the first cylinder 11 and improve the space utilization rate of the inner cavity of the first cylinder 11.

[0062] In one embodiment, the cross-sectional dimension of the first cylinder 11 is larger than the cross-sectional dimension of the second cylinder 12.

[0063] For example, such as Figure 4 As shown, both the first cylindrical body 11 and the second cylindrical body 12 are cylindrical, and the diameter of the first cylindrical body 11 is larger than the diameter of the second cylindrical body 12. The forehead body 1 is made by expanding or shrinking the tube to form a cylindrical structure with variable cross-sections at the top and bottom.

[0064] It is understood that the end face of the first cylinder 11 near the second cylinder 12 can be planar or conical; this application does not impose a specific limitation. For example... Figure 4 As shown, the lower end face of the first cylinder 11 is conical, so that the first cylinder 11 transitions evenly to the second cylinder 12.

[0065] In this embodiment, by setting the cross-sectional dimension of the first cylinder 11 to be larger than that of the second cylinder 12, the first cylinder 11 is guaranteed to have sufficient internal volume to accommodate the components, while reducing the space occupied by the second cylinder 12 and the amount of material used in the second cylinder 12, which helps to reduce the volume of the front assembly 10 and reduce the material cost of the front assembly 10.

[0066] In one embodiment, such as Figure 5 As shown, the forehead assembly 10 also includes an instrument cluster 3 and an instrument cover 4. The instrument cluster 3 is installed inside the first cylinder 11, and the instrument cover 4 is sealed at the opening of the first cylinder 11 with adhesive backing.

[0067] Instrument cluster 3 is an important information display device for the vehicle, used to display information such as drive gear, battery level, driving speed, and mileage, showing the vehicle's working status and driving information, and helping users to better control the vehicle.

[0068] The instrument cover 4 is made of a semi-transparent or transparent material to facilitate viewing the various information displayed by the instrument assembly 3. The instrument cover 4 is used to close the opening at the end of the first cylinder 11 that is away from the second cylinder 12.

[0069] The instrument cover 4 is glued to the opening of the first cylinder 11 with adhesive backing. This not only makes the operation simple, but also improves the sealing effect of the first cylinder 11, which plays a role in sealing and waterproofing, preventing water from entering the instrument assembly 3 and causing damage.

[0070] In a further embodiment, such as Figure 5 As shown, the instrument assembly 3 includes a housing 31 and an instrument panel 32. The housing 31 has a receiving cavity 311, and the instrument panel 32 is housed within the receiving cavity 311, as shown. Figure 6 As shown, the end of the housing 31 facing away from the instrument cover 4 has a mounting hole 312 communicating with the receiving cavity 311. The front assembly 10 also includes a sealing plug 5, which is inserted into the mounting hole 312, as shown. Figure 7 As shown, the sealing plug 5 has a wire harness hole 51 for allowing the wire harness to pass through.

[0071] The instrument panel 32 includes a circuit board and electronic components mounted on the circuit board. By providing a receiving cavity 311 in the housing 31, the instrument panel 32 is completely enclosed within the cavity design, which helps to improve the waterproof performance of the instrument assembly 3 and prevents water ingress into the instrument panel 32, thus preventing malfunctions.

[0072] The sealing plug 5 is a sealing element. For example, the sealing plug 5 is made of rubber or silicone material, which has good resilience, corrosion resistance, and sealing effect. By inserting the sealing plug 5 into the mounting hole 312, the end of the instrument assembly 3 away from the instrument cover 4 is sealed. Since the sealing plug 5 also has a wire harness hole 51, the wire harness of the instrument assembly 3 can be led out from the wire harness hole 51, which facilitates wire threading and management.

[0073] In this embodiment, the end of the instrument assembly 3 near the instrument cover 4 is sealed and waterproofed through the instrument cover 4 and the adhesive layer, while the end of the instrument assembly 3 away from the instrument cover 4 is sealed and waterproofed through the sealing plug 5. Both sides of the instrument assembly 3 have a good sealing effect, thus achieving bidirectional waterproofing of the instrument assembly 3.

[0074] In a further embodiment, the forehead assembly 10 also includes a wire plug 6 and a mating terminal 7. The wire plug 6 is installed inside the first cylinder 11 and has a mounting groove 61 extending along the first direction Y. The mating terminal 7 is installed in the mounting groove 61 and both ends of the mating terminal 7 in the first direction Y are used to connect wire harnesses.

[0075] For example, when a portion of the horizontal tube 2 is located inside the cavity of the first cylinder 11, the wire plug 6 can be installed on the horizontal tube 2 by means of welding, bonding, or fixing block connection; when the horizontal tube 2 is located outside the first cylinder 11, the wire plug 6 can be installed on the inner wall of the first cylinder 11 by means of welding, bonding, or interference fit.

[0076] Optionally, the wire plug 6 has a hollow structure, which helps reduce the weight and material cost of the forehead assembly 10. For example... Figure 9 As shown, the wire plug 6 also has a tapered tube 62 in the middle. The inner diameter of the tapered tube 62 gradually narrows from the end near the instrument assembly 3 to the end away from the instrument assembly 3. The tapered tube 62 is used to allow the wire harness of the instrument assembly 3 led out from the sealing plug 5 to pass through. Optionally, the tapered tube 62 has multiple elastic grooves 621, which can improve the elastic deformation capability of the tapered tube 62 so that the tapered tube 62 can adapt to wire harnesses of different sizes.

[0077] The mating terminal 7 is inserted into the mounting slot 61. The end of the mating terminal 7 closest to the instrument assembly 3 is used for electrical connection with the wiring harness of the instrument assembly 3, and the end of the mating terminal 7 away from the instrument assembly 3 is used for electrical connection with other wiring harnesses such as signal control lines and throttle lines.

[0078] In this embodiment, by setting the wire plug 6 and the docking terminal 7, the electrical connection between the instrument component 3 wiring harness and other wiring harnesses can be realized, making the arrangement of the wiring harness more reasonable, neat and clear, avoiding the messy tangling of multiple wire harnesses, which affects use and maintenance.

[0079] Furthermore, such as Figure 8 As shown, the horizontal tube 2 has a first through hole 21 and a second through hole 22. The first through hole 21 and the second through hole 22 are arranged opposite to each other along the first direction Y. Both the first through hole 21 and the second through hole 22 are used to allow the wire harness to pass through.

[0080] For example, the first through hole 21 is located closer to the instrument cluster 3 than the second through hole 22. The wire harness leading out from the instrument cluster 3 can pass through the first through hole 21 and the second through hole 22 in sequence to enter the inner cavity of the second cylinder 12, facilitating connection to the vehicle controller through the second cylinder 12; the wire harness contained in the horizontal tube 2 can pass through the second through hole 22 and be connected to the end of the mating terminal 7 away from the instrument cluster 3, thereby achieving electrical connection with the wire harness of the instrument cluster 3.

[0081] In one embodiment, there are multiple mounting slots 61, which are distributed along the edge region of the plug 6.

[0082] like Figure 9 As shown, there are six mounting slots 61, and each mounting slot 61 corresponds to a mating terminal 7. The six mounting slots 61 are spaced apart from each other and are all located on the edge of the plug.

[0083] By setting multiple mounting slots 61, multiple docking terminals 7 can be installed to facilitate electrical connection between multiple wire harnesses. By setting multiple mounting slots 61 on the edge area of ​​the wire plug 6, the wire harness contained in the horizontal tube 2 can pass through the second through hole 22 and bypass the horizontal tube 2 to connect to the lower end of the docking terminal 7, making the wiring of the wire harness more reasonable and clear.

[0084] In one embodiment, the plug 6 is interference-fitted with the inner wall of the first cylinder 11 and the plug 6 has elastic deformation capability.

[0085] Specifically, the wire plug 6 is made of highly elastic polymers such as silicone and rubber, which has good elastic deformation capability. By setting an interference fit between the wire plug 6 and the inner wall of the first cylinder 11, not only can the stable connection between the wire plug 6 and the first cylinder 11 be guaranteed, but the waterproof effect of the wire plug 6 is also improved.

[0086] In one embodiment, the first cylinder 11 is welded to the horizontal tube 2.

[0087] By welding the first cylinder 11 and the horizontal tube 2 together, not only is the operation simple, but the connection strength between the first cylinder 11 and the horizontal tube 2 is also improved, and the waterproof effect of the front assembly 10 is also improved.

[0088] This application also provides a vehicle, which includes the front end assembly 10 provided in any of the above embodiments.

[0089] Among them, vehicles can be cars, mobility scooters, scooters, balance bikes, two-wheeled vehicles, electric bicycles, and other equipment.

[0090] like Figure 10 As shown in the embodiments of this application, an electric scooter is also provided. The electric scooter includes the front assembly 10 provided in any of the above embodiments, and also includes a frame riser 20, a front wheel assembly 30, a front fork assembly 40, a rear wheel assembly 50, and a pedal assembly 60.

[0091] The top of the frame riser tube 20 is fixedly connected to the second cylinder 12 of the front assembly 10.

[0092] The front fork assembly 40 is connected to the frame seat tube 20 and the front wheel assembly 30 respectively.

[0093] The pedal assembly 60 is connected to the front fork assembly 40 and the rear wheel assembly 50 respectively, with the front wheel assembly 30 and the rear wheel assembly 50 located at both ends of the pedal assembly 60.

[0094] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0095] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein.
