[0033] Example

[0034] This embodiment addresses the common problem in existing technologies where the steering system (including the front fork, handlebars, and front frame) and pedal area often lack a rigid linkage structure. When the vehicle travels over bumpy roads or at high speeds, the front end is prone to high-frequency vibrations and lateral swaying due to the cantilever effect, severely impacting handling stability and driving comfort. Therefore, referring to... Figs. 1-2 As shown, a detachable and installable front-end reinforcement device is provided. By rigidly connecting the front frame and the foot pedal frame, an efficient force transmission path is formed to eliminate front-end vibration while ensuring that the user's foot space is not encroached upon.

[0035] Reference Figs. 1-2 As shown, a vehicle front reinforcement device includes: a base plate connector 100, a fixing component 200, and a vehicle front connector 300.

[0036] The base plate connector 100 is used to connect with the foot pedal frame of the electric vehicle; the top of the base plate connector 100 is provided with a first connecting part 120; the bottom of the fixing part 200 is detachably connected to the first connecting part 120.

[0037] The front connector 300 is used to connect with the front frame of the electric vehicle. The front connector 300 is provided with a second connecting part 310, which is detachably connected to the top of the fixed part 200.

[0038] Reference Figs. 1-2 As shown, in some embodiments, the fixing component 200 includes a first connecting plate 201, a second connecting plate 202, and a first fastener 400. The bottom of both the first connecting plate 201 and the second connecting plate 202 is provided with a first bending portion 210, which is used to connect with the first connecting portion 120. The middle portions of the first connecting plate 201 and the second connecting plate 202 are connected by the first fastener 400. In a pre-tightened state, the first fastener 400 can cause deformation of the first connecting plate 201 and the second connecting plate 202, narrowing the gap between them to pull the ends together, so that the first connecting plate 201 and the second connecting plate 202 are in a taut state.

[0039] In some embodiments, both the first connecting plate 201 and the second connecting plate 202 are provided with at least one travel groove 230 so that the middle part of the first fastener 400 can pass through at least one travel groove 230.

[0040] Reference Figs. 1-2 As shown, in some embodiments, the bottom plate connector 100 has a second bend 130 at the end near the front of the vehicle. It should be noted that the bending angle of the second bend 130 is adapted to the arc bending direction of the electric vehicle pedal connecting to the front of the vehicle, so that the second bend 130 can fit the outer contour of the connection, making the overall appearance more aesthetically pleasing and also enhancing the rigidity of the bottom plate connector 100.

[0041] Reference Figs. 1-2 As shown, in some embodiments, the bottom plate connector 100 has through-hole receiving windows 140 on both sides, which can accommodate the user's foot. For example, the receiving window 140 is a U-shaped cutout, which is suitable for shoe widths of 44-46.

[0042] In some embodiments, the front connector 300 has a U-shaped cross-section, with the two side walls of the U-shape forming second connecting portions 310. The inner sides of the U-shape are respectively connected to the top of the fixing component 200 via second fasteners 500. Exemplarily, the front connector 300 is made of bent steel plate, with the U-shaped opening width matching the top of the fixing component 200. The front connector 300 has several holes in its center, which are bolted to the front frame. For example, the front of an electric vehicle may have pre-drilled hook connection holes, which are used to connect the front connector 300. Exemplarily, the second connecting portions 310 are symmetrically arranged connecting lugs on the inner side of the U-shape, each with a Φ6.5mm hole, which are locked to the third bent portion 220 at the top of the fixing component 200 via second fasteners 500, such as M6 hexagonal bolts.

[0043] In some embodiments, the top of both the first connecting plate 201 and the second connecting plate 202 is provided with a third bend 220, which is used to connect with the front connecting member 300; and one side of the first connecting plate 201 and the second connecting plate 202 abuts against the inner sidewall of the electric vehicle front. In some embodiments, a rubber damping layer is added to the outer side of the plate, which, after pre-tightening, presses against the inner sidewall of the front to form a friction damping interface.

[0044] For example, the first connecting plate 201 and the second connecting plate 202 are arranged parallel to each other with a gap, allowing the first fastener 400 to slide within the travel groove 230 for a stroke of 3mm. The travel groove 230 is a strip-shaped groove. When the first fastener 400 is tightened, the middle part of the two plates is compressed and undergoes elastic deformation, the gap narrows, and the two ends of the plates are pulled in opposite directions, so that the bottom first bend 210 and the top third bend 220 are in a tensioned state.

[0045] Reference Figs. 1-2 As shown, in some embodiments, the base plate connector 100 includes: a base plate body 110, the base plate body 110 being provided with a plurality of mounting holes 150, the mounting holes 150 being connected to the foot pedal frame of the electric vehicle via a third fastener 600; and at least one transfer connecting plate 160, the at least one transfer connecting plate 160 being protruding from or integrally formed on the top of the base plate body 110 to form a first connecting portion 120.

[0046] In some embodiments, the corners of the base plate connector 100 are rounded.

[0047] It should be noted that the force transmission path of the front reinforcement device is as follows: front vibration energy → front frame → front connector 300 → second fastener 500 → top of fixing component 200 → bottom plate connector 100 → foot pedal frame, forming a closed-loop load-bearing structure. This converts the cantilever vibration energy into overall frame load-bearing capacity, suppressing high-frequency vibration and lateral sway.

[0048] It should be noted that the pre-tightening mechanism, with the first fastener 400 cooperating with the travel groove 230, causes the two connecting plates to elastically deform and the gap to narrow when tightened, so that the bottom first bend 210 and the top third bend 220 are in a continuous tension state, thereby increasing rigidity.

[0049] It should be noted that the U-shaped 140-degree accommodating window ensures that the user's feet are placed naturally, avoiding the potential danger of traditional reinforcements encroaching on the pedal area. The fully rounded corner transition design eliminates the risk of scratches and meets ergonomic requirements.

[0050] It should be noted that this device features adaptive installation and high compatibility, with a detachable modular structure: each connection part is assembled with fasteners, supporting quick assembly and disassembly.

[0051] The electronic devices provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
