Description

Technical Field

[0001] This invention relates to the field of electric bicycle accessories technology, and in particular to an electric bicycle panel with LED display function. Background Technology

[0002] As an important means of modern green travel, electric bicycles are becoming increasingly popular. The control panel, as the core component for information interaction between electric bicycles and users, not only displays basic instrument data, but is also gradually developing towards intelligent and personalized graphic and text display, integrating more and more display modules and communication components.

[0003] As the functions of the display panel become more diverse, the ease of disassembly and assembly as well as the stability of the connection become particularly important when the internal electronic components of the device malfunction and need to be repaired, or when users need to upgrade to a new type of display panel. However, most existing electric bicycle panels are assembled and connected to the base of the vehicle body using traditional methods such as bolt drilling and locking or rigid plastic clips forcibly pressing.

[0004] Panels fixed with traditional bolts require specific hardware tools for installation and removal, making the process cumbersome, time-consuming, and labor-intensive. Furthermore, in the context of long-term outdoor riding of electric bicycles, the threaded structure is prone to stripping or loosening due to high-frequency vibration. Panels fixed with ordinary rigid clips lack dynamic elastic buffering and a deep physical self-locking anti-fall-off mechanism. When subjected to severe impacts from the road surface, the clips are prone to breakage or failure, resulting in unstable overall panel connection. This makes it difficult to simultaneously meet the dual requirements of tool-free quick disassembly and assembly and high-strength, stable locking.

[0005] Therefore, this invention proposes an electric bicycle panel with LED display function to overcome the shortcomings of the prior art. Summary of the Invention

[0006] To overcome the above shortcomings, the present invention provides an electric bicycle panel with LED display function, which aims to improve the problem that some existing electric bicycle panels with LED display function use traditional bolts and ordinary rigid buckles for assembly and fixation, resulting in the need for specific hardware tools and time-consuming and laborious operation during installation and disassembly.

[0007] This invention provides an electric bicycle panel with LED display function, including a protective shell and a bottom shell fixedly connected to the bottom end face inside the protective shell, and including a matching base and a plug shell as a movable docking structure. The plug shell has a built-in elastic avoidance and self-locking linkage structure. The plug shell is vertically fixedly connected to the bottom outer end face of the bottom shell. The base is slidably fitted onto the outer side surface of the plug shell. The base has a groove formed on its inner vertical wall. Furthermore, a pressing column is slidably connected to the inside of the plug shell along the vertical direction. The vertical side wall of the plug shell slides through... A limiting ball is provided, and the inner end face of the limiting ball is physically linked to the outer side surface of the extrusion column by mutual abutment. The outer end face of the limiting ball extends outward into the groove of the base, and the outer contact surface of the limiting ball and the inner surface of the groove of the base form a mechanical dead angle limiting by mutual sliding engagement. In addition, a spring is fixedly connected to the top horizontal end face of the extrusion column along the vertical direction. The end of the spring away from the extrusion column is fixedly connected to the inner horizontal top wall of the insert, forming an internal force-bearing module for dynamic force storage and reset ejection.

[0008] Preferably, a display unit is fixedly connected to the internal support surface of the protective shell, and Bluetooth is electrically connected to the external side of the display unit. The spatial layout combined with the electrical structure establishes the hardware foundation for the panel to receive image data and perform real-time visualization with an external smart terminal.

[0009] Furthermore, a charging cable is electrically connected to the outer surface of the Bluetooth device, and a charging port is electrically connected to the end of the charging cable away from the Bluetooth device. The charging port is fixedly connected to the outer vertical wall of the protective shell. The outer insulating surface of the charging cable is tightly attached to the inner vertical sidewall of the protective shell. This close-fitting wiring structure plays an auxiliary protective role in preventing the internal communication and power supply lines from becoming messy, tangled, or broken due to friction under long-term vibration.

[0010] Preferably, the outer vertical sidewall of the extrusion column is parallel to the inner vertical sidewall of the insert housing, and the outer vertical sidewall of the extrusion column slides in contact with the inner vertical sidewall of the insert housing. At the same time, the vertical central axis of the spring coincides with the vertical central axis of the extrusion column, and the outer edge surface of the spring is parallel to the inner vertical sidewall of the insert housing. The tight dimensional fit and spatial coaxiality design provide a physical guiding basis to ensure that the extrusion column yields smoothly under force and to prevent the spring from bending and becoming unstable under pressure.

[0011] Furthermore, the bottom edge of the protective shell abuts against the top edge of the bottom shell, and the bottom edge of the protective shell is parallel to the top edge of the bottom shell. This large-area parallel abutment splicing eliminates assembly gaps and significantly improves the sealing, dustproof, and waterproof performance of the entire machine in complex outdoor weather conditions.

[0012] Preferably, the top horizontal end face of the base is parallel to the bottom horizontal end face of the bottom shell, and the top horizontal end face of the base abuts against the bottom horizontal end face of the bottom shell. The rigid planar fitting structure provides an extremely stable support surface after quick installation, effectively resisting vertical bumps and impacts during riding.

[0013] The present invention has the following beneficial effects: 1. This invention, by vertically fixing an insert shell to the outside of the base shell, and setting an interlocking extrusion column, a limiting ball, and a spring inside the insert shell, causes the limiting ball to slide inward under pressure when inserted into the base, pushing the extrusion column to compress the spring and store force. When it reaches the groove of the base, the spring releases its potential energy to push the extrusion column to reset and push the limiting ball outward to lock into the groove. This solves the problems of time-consuming and laborious panel installation and disassembly and unstable mechanical connection in the prior art, and achieves the technical effect of instantly completing the stable locking and quick disassembly of the panel without professional tools.

[0014] 2. This invention solves the problems of limited functionality and lack of intelligent information display structure in existing electric bicycle panels by fixing a display unit inside the protective shell, electrically connecting Bluetooth to the side of the display unit, and providing a charging cable and charging port. It achieves the technical effect of receiving graphic and textual data commands sent by external smart terminals for real-time intuitive display and providing stable and safe power supply for internal electronic components.

[0015] 3. This invention solves the problems of poor water and dust resistance of the lower panel in outdoor complex weather, and the easy tangling and wear and breakage of the internal wiring harness under long-term vibration environment. It achieves the technical effects of eliminating structural assembly gaps, building a highly stable rigid load-bearing defense line, improving the shock and impact resistance of the whole machine, and extending the service life of internal electrical components. By making the bottom edge of the protective shell abut against the top edge of the bottom shell and the top horizontal end face of the base abut against the bottom horizontal end face of the bottom shell over a large area, and tightly attaching the internal charging cable to the vertical side wall inside the protective shell, this invention solves the problems of poor water and dust resistance of the lower panel in outdoor complex weather, and the easy tangling and wear and breakage of the internal wiring harness under long-term vibration environment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Reference Figures 1 to 5 The present invention provides an electric bicycle panel with LED display function, which aims to solve the problems of time-consuming and laborious installation and disassembly of the panel and the lack of intelligent information display structure support in the prior art.

[0020] like Figure 1 and Figure 2As shown, the device includes a protective shell 1 and a bottom shell 2 fixedly connected to the bottom surface inside the protective shell 1. The protective shell 1 serves as external protection and a load-bearing space for the internal electronic components, while the bottom shell 2 serves as a bottom support base and provides a downward-facing load-bearing foundation. A plug shell 8 is vertically fixedly connected to the outer bottom surface of the bottom shell 2. A base 7 is slidably fitted onto the outer side surface of the plug shell 8. The base 7 is pre-installed in the electric bicycle frame as a fixed load-bearing base. The plug shell 8, as a movable docking structure, is inserted downward into the base 7 for guidance and positioning. A groove is provided on the inner vertical wall of the base 7, providing a mechanical dead angle to limit the upward detachment of external components. The interior of the plug shell 8 is along... A compression column 9 is slidably connected in the vertical direction. The compression column 9 receives the horizontal force and converts the lateral force into a vertical mechanical displacement. A limiting ball 10 is slidably inserted through the vertical side wall of the insert shell 8. The limiting ball 10 acts as a movable locking tongue. When it is compressed, it retracts inward and pops outward after reaching the designated position. The inner end face of the limiting ball 10 abuts against the outer side surface of the compression column 9. The outer end face of the limiting ball 10 extends outward into the groove of the base 7. The outer contact surface of the limiting ball 10 slides and engages with the inner surface of the groove of the base 7. The physical compression and engagement cooperation allows the panel body and the pre-embedded fixing end to quickly lock the structure.

[0021] A spring 11 is fixedly connected to the top horizontal end face of the extrusion column 9 along the vertical direction. The end of the spring 11 away from the extrusion column 9 is fixedly connected to the inner horizontal top wall of the insert shell 8. When the extrusion column 9 slides upward, the spring 11 undergoes elastic compression deformation and accumulates potential energy for downward release. When the limiting ball 10 reaches the groove position, it releases a rebound thrust to press the extrusion column 9 down to reset, thereby pushing the limiting ball 10 outward and firmly locking it into the groove.

[0022] Reference Figure 1 and Figure 3 The protective shell 1 has a display unit 6 fixedly connected to its internal support surface. The display unit 6 receives external data commands and displays images and text information to the outside world. The bottom end face of the display unit 6 is fixedly attached to the top horizontal surface of the bottom shell 2. The bottom shell 2 provides a stable support structure for the display unit 6 and prevents the display unit 6 from shifting due to vibration under various road conditions. The external side of the display unit 6 is electrically connected to a Bluetooth 4. The Bluetooth 4 establishes a wireless communication connection with an external smartphone device and is responsible for transmitting the received image and text data to the display unit 6 in real time for display. The outer end face of the Bluetooth 4 is fixedly connected to the internal side wall of the protective shell 1. The physical position limitation ensures that the stability of the Bluetooth 4 signal transmission is not interfered with by other internal mechanical structures. The bottom outer end of the Bluetooth 4 is electrically connected to a charging cable 3, which guides and safely transmits externally input electrical energy.

[0023] Reference Figure 1 and Figure 2The end of the charging cable 3 furthest from the Bluetooth 4 is electrically connected to a charging port 5. The charging port 5 is directly plugged into an external power connector and obtains the power required for the continuous operation of the internal electronic components. The outer surface of the charging port 5 is fixedly connected to the outer side wall of the protective shell 1. The outer insulating surface of the charging cable 3 is tightly attached to the inner vertical side wall of the protective shell 1. The close-fitting cable routing method avoids the cable bundle from becoming messy and tangled inside the protective shell 1. The bottom edge surface of the protective shell 1 and the outer edge surface of the bottom shell 2 are attached to each other and sealed together. The sealed connection method and the physical splicing structure of the bottom edge end face of the protective shell 1 and the top edge end face of the bottom shell 2 abutting against each other and being parallel to each other significantly improve the outdoor dustproof and waterproof protection capability.

[0024] Reference Figure 4 and Figure 5 The outer vertical sidewall of the extrusion column 9 is parallel to the inner vertical sidewall of the insert shell 8, and the outer vertical sidewall of the extrusion column 9 and the inner vertical sidewall of the insert shell 8 slide against each other. The vertical central axis of the spring 11 coincides with the vertical central axis of the extrusion column 9, and the outer edge surface of the spring 11 is parallel to the inner vertical sidewall of the insert shell 8. The tight dimensional fit ensures that the extrusion column 9 smoothly retracts along a straight trajectory when under force and prevents the spring 11 from bending laterally and losing its energy storage and rebound ability when compressed. The top horizontal end face of the base 7 is parallel to the bottom horizontal end face of the bottom shell 2, and the top horizontal end face of the base 7 and the bottom horizontal end face of the bottom shell 2 abut against each other. The large area of ​​rigid surface abutment provides an extremely stable support section after quick installation and effectively resists the bumps and impacts during riding.

[0025] The bottom edge of the protective shell 1 abuts against the top edge of the bottom shell 2, and the bottom edge of the protective shell 1 is parallel to the top edge of the bottom shell 2. The top horizontal end face of the base 7 is parallel to the bottom horizontal end face of the bottom shell 2, and the top horizontal end face of the base 7 abuts against the bottom horizontal end face of the bottom shell 2. The large-area parallel abutting design of multiple end faces completely eliminates assembly gaps and builds a highly stable rigid load-bearing defense line. The outer insulating surface of the charging cable 3 is tightly attached to the inner vertical side wall of the protective shell 1, and the charging port 5 is fixedly connected to the outer vertical wall of the protective shell 1. The tightly attached wall-mounted cable layout effectively avoids messy tangling of internal communication and power supply lines.

[0026] The working principle is as follows: When the bottom shell 2 with the insert shell 8 is aligned with the base 7 and pressed downwards into the interior of the base 7 in the vertical direction, the outer side surface of the insert shell 8 moves downwards inside the base 7. During the downward sliding process, the inner vertical wall of the base 7 exerts an inward physical pressure on the outer contact surface of the limiting ball 10. The limited ball 10, under pressure, slides inwards along the vertical side wall of the insert shell 8 in the horizontal direction. The inner spherical surface of the inwardly sliding limited ball 10 is tangentially attached to the outer side surface of the extrusion column 9 and extrudes the outer side surface of the extrusion column 9. The tangential arc surface cooperation converts the horizontal thrust into a vertically upward component force. The extrusion column 9, under the thrust, slides upwards in the vertical direction inside the insert shell 8 and compresses the spring 11 upwards. The spring 11 undergoes elastic compression deformation under the vertically upward pressure and accumulates elastic potential energy for downward rebound. When the insert shell 8 is inserted downwards to reach the finger... When the outer contact surface of the limiting ball 10 slides to the groove position inside the base 7 at a fixed depth, the pressure resistance of the inner vertical wall of the base 7 against the outer contact surface of the limiting ball 10 disappears. At this time, the elastically deformed spring 11 releases elastic potential energy downward and generates a vertically downward rebound force. The rebound force presses down on the top horizontal end face of the extrusion column 9. The extrusion column 9, which is pushed down, slides and resets vertically inside the insert shell 8. The extrusion column 9, which slides down and resets, pushes the inner spherical surface of the limiting ball 10 horizontally outward. The outer end face of the pushed limiting ball 10 extends outward into the groove of the base 7. Finally, the outer contact surface of the limiting ball 10 and the inner surface of the groove of the base 7 form a firm mutual sliding and locking state. The instantaneous locking of mechanical and physical linkage completely solves the problems of time-consuming and laborious panel installation and unstable connection in the prior art.

[0027] After the mechanical and physical fixation is completed, the external power connector inputs electrical energy through the charging port 5 connected to the outer vertical wall of the protective shell 1. The electrical energy is transmitted along the charging cable 3 that is tightly attached to the inner vertical side wall of the protective shell 1. The transmitted electrical energy provides operating power for the display unit 6 and Bluetooth 4 connected to the inner support surface of the protective shell 1. After being powered on, Bluetooth 4 receives graphic data commands sent by external smart terminals through wireless signals. Bluetooth 4 transmits the received data commands to the display unit 6 in real time through the electrically connected lines. The display unit 6 receives the command data and displays text and images to the outside world. The complete electrical signal transmission and display process greatly satisfies the intelligent information display needs of the panel in the riding environment.
